Thermal drive for greenhouses: automatic opening and ventilation, hydraulic cylinder with own hands from shock absorber

A comfortable microclimate for plants in the greenhouse can be controlled with the thermal drive . In Russia, fertile lands are located, but in the mid-zone climate is not very favorable, in other words, severe. That spring frosts, then autumn rains, all this can have a detrimental effect on the crop, on seedlings. Given the global warming, the weather is not predictable, and every year it changes, and it was necessary to seek a solution to this problem. Ever since the reign of the tsar, they have found a solution to how to preserve the harvest from the harsh climatic conditions. Then greenhouses were created. Of course, the kings had entire greenhouses. Now in the country or at the manor site, a simpler design is used - so-called greenhouses-greenhouses. These constructions are a great necessity. Naturally, for what grows there, you need attention, in time to ventilate or close, but all the time we can not stay at the greenhouse, for this purpose we created a device like a thermal drive. There are several types of automatic thermal drives, but the principle of operation and the purpose of their use are the same for all.

Opening of the greenhouse in automatic mode: installation of the thermal drive

What is a thermal drive, and how to use it?Any amateur horticulturist has often thought about easing work on the site. To facilitate work, in our time there is already a huge amount of automation.

This device may well provide for the ventilation of the greenhouse in your absence

For example:

• Various sprinklers;
• Pumps;
• And much more automatic equipment and machinery.

One of them is a thermal drive for greenhouses. The thermal drive for greenhouses is a mechanism that allows, without the participation of human efforts, to open or close the ventilation mechanisms of the greenhouse.

Ventilation systems include the process of opening the doors of a greenhouse or a ventilator.

When heated to a certain temperature, the thermal drive itself will ensure the opening of the greenhouse. A person will only have to enjoy this process, which is called automatic.

Ventilation of the greenhouse in automatic mode: operation of the

thermal drive Automation of the ventilation of the greenhouse is necessary. Often a person simply by virtue of his abilities can not always be near her. A good ventilation is necessary, for this purpose there is a thermal drive.

The thermal drive is designed to automatically open( close) the door, window, frame when changing the temperature inside the greenhouse.

For this it is necessary to ventilate:

• To get rid of excess moisture, it is impossible to create conditions for reproduction of unfavorable bacteria;
• For photosynthesis, as fresh air is necessary for all living things;
• Also airing will affect how much plants will be pollinated;
• To ensure a favorable climate for plants.

In other words, in the common people this drive is called an automatic ventilator. This installation is not mechanical, but fully automated. Does not require constant attention or any other intervention. What is good ventilation for greenhouses?Good ventilation is needed to get rid of excess moisture, to reduce the temperature in the greenhouse itself.

Stages of self-assembly of the thermal drive for greenhouses of the shock absorber

The device is so simple that it can be assembled by hand with literally easily accessible means, for example, an automobile shock absorber. You can use the shock absorber and of course from the chair, the mechanism of which lowers and raises it, but we will understand the example of an automobile.

In order to make a thermal drive from a shock absorber and other improvised materials with your own hands, you do not need special knowledge.

Instruction:

• 2 pipes, preferably metal, 1 m long;
• The ends of these pipes require threading to connect them;
• When connecting 2 pipes, use the tee;
• Other ends with blind plugs that are used for plumbing purposes;
• Then take the shock absorber, and cut off the bottom of the hairpin;
• At the bottom we drill a hole, 8 mm in diameter;
• Use the brake hose bolt and nut;
• Bolt drill through;
• We drill the plug in the center, and from inside we insert this bolt, wind the nut.

Paranitic gaskets should be located in all connections. And the final step is to unscrew the cap and fill the oil in the hydraulic element. That's so easy and simple you can make your own machine, which will ensure the ventilation of the greenhouse.

Hydraulic cylinder - this is the 2 pipes that were taken at the very beginning.

So, self-made thermal drives are no less effective than factory ones. But if you compare different systems, then Ufopar has the advantage, due to the quality of assembly, warranty period.

Description of thermal drive brand for greenhouses TP 04

This universal thermal actuator can be installed on any opening or closing mechanism. Since there is no electric drive, it does not need wires, timers and so on. It drives a liquid that is flooded into the cylinder.

The essence of the thermostat is clear from the name, it is designed to regulate the room temperature

When this mechanism is in operation, when the rod starts to slide out, the following occurs:

• Pins;
• Windows;
• Doors. Approximate operating temperature from 23 to 26 ᵒС.

.The installation of this mechanism is very simple. Such automation will help to easily ensure the influx of fresh air and ventilation.

When heated, the liquid expands and the thermal cylinder starts to work.

Reviews of owners of such thermal drives, remain only positive. Satisfied with the purchase of gardeners recommend all the thermal drive, who has greenhouses, cares for the plants inside it and expects a good harvest.

Advantages of thermal drive( TP) of greenhouses

It is not difficult to install the equipment on a greenhouse. It is not necessary to bring electricity to the greenhouse or to acquire a large number of batteries. When heated to the required temperature, the liquid inside is allowed to expand and fill a separate chamber. As it fills, it acts on the rod, which forces the flap to open. The reverse principle of work is quite the opposite of this action. When cooled, the liquid contracts and moves the rod in the opposite direction.

The thermal actuator is designed to control both a raised ceiling frame ideal for ventilation and a swing window, a window, an entrance door.

The advantages of this thermal drive include:

• Reliability, even after the warranty period has expired, He will serve a long time for a long time;
• Easy to handle, such thermal drives, as a rule, do not require any adjustments;
• Easy to install, all the necessary details of fasteners in the kit and nothing extra.

Easy installation, will easily install it on our greenhouse. Before starting the installation, you need to check how easy it is to open the door of the greenhouse. After the installation pencil or marker, you must indicate the place where this mechanism will be fixed.

The bracket directly in the kit must be fastened so that the stem in the other part of the part extends 10 cm.

Drill 2 holes, and attach the rod to the screws to the wall of the greenhouse. The other bracket is attached to the door so that when opening the distance between the centers of the brackets is not more than 45 cm. So, one bracket should be fixed to the frame, the second one on the wall of the greenhouse. Next, fixers are put on the thermal drive, and then on the gas spring itself. The ball supports on the brackets will serve to attach the thermal drive and the gas spring to them. Next we check the efficiency. For curling, the counterweight on the windows is used, without damaging the opener. These thermal drives can be purchased in various stores for gardeners, or, knowing now their design, you can make such a mechanism yourself. The assembly of such a mechanism will be a little less costly than buying it.

So, the dreams of gardeners have been realized. Automation is present almost everywhere, and even a greenhouse is no exception. Such a device can easily take care of plants in the greenhouse during the absence. In the cold it will not freeze, in heavy rain it will not fill the plants, since the opening and closing systems of the ventilation pans will take care of this. At night spring or autumn frosts, will not allow to ruin a crop and will keep the necessary temperature. Do not have to, leaving from the dacha or infield, think about what will happen during the absence. Do not need to ask neighbors to follow the site. The thermal drive will solve the problems and help stop worrying about it. Automatic thermal drive is one of the best solutions to these problems.
