The invention relates to structures protected ground, namely the greenhouse.

Known greenhouse, containing the skeleton of arcuate sectors, hinged on the axis, film coating and side panel, and the sectors have arc lengths more than a quarter of a circle, but not less than its half, and sectoral frameworks are on the same axis with the greenhouse and are concentric with the axis of the mounting /see USSR author's certificate No. 852248, class A 01 G 9/14, 1978/.

The lack of analogue is the lack of automatic ventilation of the greenhouse when the undesirable temperature rise in it.

Also known greenhouse, including the frame and translucent floor, and the roof frame made of pipes and installed on the axis of rotation and has a contrast with the rotation limiter of the roof, and the internal cavity of the tube is under vacuum and partially filled with legalassistance liquid, such as ether /see USSR author's certificate No. 463423, class A 01 G 9/14, 1973/.

This greenhouse is closest to the proposed type of drive unit for automatic ventilation of the greenhouse, so it is taken as a prototype.

To the disadvantage of the prototype should include large dimensions and weight of the host for automatic ventilation, so as to ventilate the greenhouse should be able to raise all of the sludge is the part of the roof, the axis of rotation which is in the horizontal plane.

The technical result of the invention is reducing the size and weight of the drive unit automatic ventilation of the greenhouse.

The technical result is achieved in that in a greenhouse, comprising a frame in the form of longitudinal walls, end panels and roof, translucent material in the openings of the frame, part of which is arranged to open and close for ventilation of the greenhouse, and a drive unit for automatic ventilation, consisting of bonded and fixed to rotate in a vertical plane of the tube with a vacuum, partially filled with legalassistance fluid, and an adjustable counterweight, according to the invention, the frame openings to ventilate the greenhouse is made in the form posted on the longitudinal walls or end panels, air vents mostly with a vertical axis of rotation, and a drive unit automatic ventilation is supplied by a system of levers pivotally fastened to each other and doors, air vents and fixed to the fastening element between a tube and counterweight.

In addition, the tube may be made in the form of two cameras, a cavity which is communicated between a pipe of small cross section.

The invention is illustrated in the drawings, which depict:

- figure 1 - offer the Naya greenhouse, open air vents;

- figure 2 is an embodiment of a tube.

The greenhouse includes installed on the Foundation 1 longitudinal wall 2, side panel 3 and the roof 4, made of a skeleton, the openings of which are closed translucent material. In the end panels have flaps 5 and 6 to ventilate the greenhouse, at one side or in side panel/ there is a door 7.

Inside the greenhouse on the roof of the fixed bracket 8 with the axis 9, the latter can be rotated worn bushing 10. The sleeve is rigidly fixed to the upper 11 and lower 12 levers and sealed tube 13, in the lower part of which is filled legalassistance liquid /for example, ether/and in the upper - created vacuum.

To the tube or sleeve/ attached threaded rod 14 with put on him by carving a counterweight 15. To the lever 11 through Werner 16 connected rod 17, which hinge 18 is connected with the window 5. The lever 12 through the hinge 19 is connected rod 20 that is associated with the window 6 by hinge 21. The bracket has a stop 22 that restricts the rotation of the tube - bushing - pivot - levers clockwise.

Tube 13 for a more efficient displacement of its center of gravity when the temperature changes can be performed from the end chambers 23 and 24, the cavity which is communicated between a pipe 25 small section.

The greenhouse is ventilated as follows.

At normal temperature in which Alice fluid in the tube 13 takes up less space the overall center of gravity of the swivel axis 9 of the system is to the left of the point of suspension and the system is rotated along arrow B to the position in which the flaps 5 and 6 are closed.

When the temperature of the liquid in the tube expands, the center of gravity of a liquid is moved to the right while moving and the overall center of gravity of the rotating system to the right. The system rotates along arrow a, the levers 11 and 12 push pull 17 and 20 in the direction of the air vents and the last opened for ventilation. When the temperature drops to normal, the liquid in the tube decreases in volume, its center of gravity moves to the left from the point of suspension /axle 9/, shifting to the left and the center of gravity of the entire system, which is rotated along arrow B and by means of the rod closes the window.

When running the tube 13 in figure 2 the fluid from the chamber 23 through the pipe of small cross section fills the chamber 24 and moves the center of gravity of the tube with liquid to the suspension point /axis 9/.

The temperature at which you want to open or close vents, adjustable by rotation of the counterweight 15 on the threaded rod 14, i.e. by changing the position of the common center of gravity of the system.

Greenhouse, including the frame for longitudinal walls, end panels and roof, translucent material that closes the openings of the frame, part of which is arranged to open to ventilate the greenhouse, and p is the water node for automatic ventilation, consisting of bonded and fixed to rotate in a vertical plane of the tube with a vacuum, partially filled with legalassistance fluid, and a counterweight, wherein the openings of the frame to ventilate the greenhouse is made in the form posted on the longitudinal walls or end panels, air vents mostly with a vertical axis of rotation, and a drive unit automatic ventilation equipped with a system of levers pivotally connected with the window and rigidly connected with the tube, the latter being made in the form of two end chambers, cavities are communicated between a pipe of small cross section.
