Automatic opening of greenhouse doors: how to make

21-01-2018
Doors

The device of the door in the greenhouse can be quite different. This may be a simple door, and maybe in the form of a window, just the size is chosen large.

It depends on the area of ​​the greenhouse. Sometimes it is extremely important, because overheating will affect the yield. In this article we will describe how to make the doors in the greenhouse with automatic opening. You can watch it on the video that is presented in this article and see all the stages of the work on the photo.

We make automatic hydraulic

The whole structure is quite simple to manufacture and you can do everything with your own hands. Then the price of the design will be low. Next will be offered instructions for doing this work.

Principle of operation

Here everything is done according to the physical properties of the material.

Everything is quite simple:

  • When heated, the plastic container will warm the liquid inside and the air too. Everyone knows that when heated, these components expand;
  • When heated inside the liquid creates pressurewhile the liquid increases and simply flows into another tank, only the second tank should have a smaller volume;
  • Two tanks are connected to each other through the unit. Liquid entering another tank will increase its weight;
  • Through the string, we will have a connection with a window leaf and it will open;
  • When cooling air, and then all the liquid will occur in the opposite direction.

Note: This law of physics can be perfectly applied to automatically open the door. This is especially true if you do not have a large room and the window is simply not provided.

What is needed

The price of this design is quite low, you will all be able to find a house and you will not need to spend it.

So:

  • Any metal container will be useful. By volume, it should be about four liters;
  • Need cork, which should tightly close the container. You can use a simple foam. You can also apply and not the necessary piece of rubber;
  • For the overflow of water, we need a tube. They can be made of plastic and metal. Practically any will suit, as long as there are no holes. At the end of the tube is put on a rubber hose, most importantly, it should not reach the bottom of the container. The tube should be connected to the container tightly. You can even solder. If you want, then you can do it and sealant.

Manufacturing process

Now let's do the manufacturing process together and look at each stage of the work.

So:

  • We take the prepared container and fasten the tube to it. The joint is made airtight;
  • In this capacity we collect liquid about 40 percent. You can pour not only water, but also antifreeze. It will not evaporate;
  • All this tightly close and fasten fasten on the top of the greenhouse. Capacity must be kept tight;
  • Now we take a smaller container. We make a hole in the tube and put the hose there. The connection must also be airtight;
  • Now add the liquid, its level should be above the level of the hole in the tube from the bottom edge, about one cm;
  • Now we take a soft rubber tube and connect both containers, the seam should be completely sealed.

We connect capacities by means of a flexible hose

Make adjustment

Over this issue will need to work and experiment. The heavier the door, the heavier the capacity should be.

Caution: All adjustments must be made at an average temperature. Do not make it too hot and too cold. You can't do it right then.

 So:

  • When adjusting, look at the weight of the door. It can be closed even with a large load, it all depends on the weight of the door itself;
  • If you want the door to close only on its weight, then the lower timber becomes heavier or simply shift the center of rotation by a few cm. This is all regulated in place;

This method is the easiest and most effective. You can use engine oil as a fluid. It will not evaporate and you will not have to periodically add water there.

On our site you can find many articles about door automation. Just for each, you need to pick up your modification. Doors are in any room and it is not always advisable to use expensive electronics.
