Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, in particular to an antifreeze and heat preservation device for greenhouses. Background Art

[0002] A greenhouse is a frame-covered structure with excellent thermal insulation performance. Its appearance allows people to eat off-season vegetables. Generally, vegetable greenhouses use a bamboo or steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space.

[0003] A greenhouse antifreeze and heat preservation device in the prior art (Announcement No.: CN219939114U) is slidably installed inside the L-shaped frame by setting a connecting pin, and the connecting pin is inserted into the connecting groove of another antifreeze and heat preservation cover, so that the staff can select the appropriate number of antifreeze and heat preservation covers for splicing according to needs. However, multiple greenhouses often require sealing gaskets at the splicing points to make the splicing points more sealed. However, the sealing gaskets are prone to aging and damage after long-term exposure to wind and sun, and need to be replaced. When replacing the equipment, the corresponding greenhouses need to be moved and separated first. This will cause the two greenhouses to be connected after the sealing gaskets are replaced, resulting in poor sealing at the splicing points. Therefore, it is urgent to design a greenhouse antifreeze and heat preservation device that is easy to replace the sealing gaskets. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that after replacing the sealing pads at the joints of two greenhouses, the two greenhouses are prone to splicing deviation when they are connected again, which is not conducive to the subsequent insulation function of the greenhouses. A greenhouse antifreeze and insulation device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A greenhouse antifreeze and heat preservation device comprises two supporting beams, a top plate is fixedly installed on the top between the two supporting beams, two winding mechanisms are symmetrically arranged on the top of the top plate, a first connecting frame and a second connecting frame are respectively fixedly installed on the far sides of the two supporting beams, a sliding groove is provided on the near sides of the first connecting frame and the second connecting frame, a docking groove is provided on the other side of the first connecting frame, a sealing gasket is bonded to the inner wall surface of the docking groove, a docking block adapted to the docking groove is fixedly installed on the other side of the second connecting frame, a screw rod and a positioning pin are provided above the first connecting frame, and two connecting plates are symmetrically fixedly installed on the surface of the second connecting frame.

[0007] As a further technical solution of the utility model, the screw rod and the positioning pin are symmetrically distributed, the screw rod is rotatably installed on one side of one of the support beams, and the positioning pin is fixedly installed on the surface of the corresponding support beam.

[0008] As a further technical solution of the utility model, guide holes matched with the positioning pins and threaded holes matched with the screw rods are respectively opened on the surfaces of the two connecting plates.

[0009] As a further technical solution of the utility model, a second motor is fixedly mounted on the surface of the support beam, and an output end of the second motor is fixedly mounted to a rotation center of one end of the screw rod.

[0010] As a further technical solution of the utility model, the winding mechanism includes a thermal insulation curtain and a reel, the thermal insulation curtain is rolled up on the surface of the reel, and the two sides of the movable end of the thermal insulation curtain are respectively slidably installed in the slide grooves opened in the first connecting frame and the second connecting frame.

[0011] As a further technical solution of the utility model, a driving gear and a driven pulley are fixedly sleeved on the same end surface of the two reels, a first motor is fixedly installed on one side of the support beam, and a first belt is sleeved between the output end of the first motor and one of the reels.

[0012] As a further technical solution of the utility model, a driven gear is rotatably installed on one side of the support beam, a driving pulley is fixedly installed on one side of the driven gear, the driven gear is meshed with the driving gear, and a second belt is sleeved between the driving pulley and the driven pulley.

[0013] The beneficial effects of the utility model are:

[0014] 1. By setting up the first connecting frame and the second connecting frame for use together, a docking block on the surface of the second connecting frame of a greenhouse is embedded in the docking groove on one side of the first connecting frame of another fixed greenhouse, and the sealing gasket is bonded to the docking groove of the first connecting frame. This can provide good protection for the sealing gasket, reduce weathering damage, and increase the service life of the sealing gasket. At the same time, the docking is more precise and deviation in the docking is avoided.

[0015] 2. By setting the positioning pins and docking plates, it is convenient to position the two greenhouses when docking. A screw rod is set, which can be rotated and threadedly connected to the docking plate to achieve locking after docking, thereby improving the stability of the equipment after docking. In addition, through the positioning pins and screw rods, when replacing the sealing gasket, the greenhouse that is freed from the surface restrictions can be separated from the fixed greenhouse under the reverse rotation of the screw rod, which further facilitates the operation of replacing the sealing gasket and effectively solves the problem of inaccurate docking of the two greenhouses when docking after separation.
