[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] Based on the problem of frequent manual winding and unwinding of thermal insulation film in the prior art, which is labor-intensive, the present application provides a greenhouse structure that can replace manual force for winding, so as to make winding and unwinding more labor-saving.

[0021] Figure 1 The schematic diagram of the structure of the cold-proof and heat-insulating device for growing longevity vegetables is shown; Figure 1In the invention, the cold-proof and heat-insulating device for growing longevity vegetables comprises a supporting bridge 110, on the end surface of the supporting bridge 110, a plurality of supporting beams 120 are laid along the track thereof, the plurality of supporting beams 120 can cooperate to form a supporting surface, on the supporting surface, a film cloth 130 is laid, and driving parts are arranged on both sides of the supporting bridge 110, the driving parts comprise a driving motor 140 and a winding roller 150 installed at the output end of the driving motor 140, and the two ends of the film cloth 130 are respectively connected to the two winding rollers 150; the two groups of winding rollers 150 rotate in the same direction to realize winding and / or unwinding; in actual use, the two driving motors are started at the same time, and the film cloth 130 is wound around the two winding rollers 150, and the two winding rollers 150 are ... The machine 140 is used to rotate the two rollers 150 in the same direction, that is, one roller 150 starts to reel in and the other roller 150 starts to unreel in order to change the position of the membrane cloth 130, thereby realizing the storage and laying of the membrane cloth 130, releasing manpower and reducing labor intensity; the support beam 120 is rotatably connected to the support bridge 110; when the membrane cloth 130 slides on the support surface, the support beam 120 can be driven to rotate accordingly, so as to convert the sliding friction between the membrane cloth 130 and the support surface into the rotational friction between the membrane cloth 130 and the support beam 120, thereby reducing the possibility of damage or deformation of the membrane cloth 130 during reeling or laying.

[0022] Figure 2 The schematic diagram of the state structure of the cold-proof and heat-insulating device for growing longevity vegetables is shown; Figure 3 A schematic diagram of the structure at the movable beam 230 is shown; Figure 2 and Figure 3In the embodiment, a movable beam 230 is connected to the junction of the support bridge 110 and the ground, and the membrane cloth 130 passes through the movable beam 230 and is connected to the roller 150; through the movable beam 230, the lowest point of the membrane cloth 130 can be forced to remain in contact with the ground, thereby ensuring the insulation effect in the shed; a slideway 210 is provided on the support bridge 110, and the bottom of the slideway 210 extends to the ground, and the movable beam 230 can be slidably connected to the slideway 210; because the movable beam 230 can be slidably connected in the slideway 210, the movable beam 230 can be slidably connected to the slideway 210. The movable beam 230 slides along the track of the slideway 210 to approach and / or move away from the ground. Under normal conditions, the movable beam 230's own weight can press the membrane cloth 130 to fit the ground to ensure thermal insulation. When rolling or laying the film, first, the two rollers 150 are rotated in opposite directions and both roll up the membrane cloth 130 to make the membrane cloth 130 tight and lift the movable beam 230 away from the ground. Then, the two rollers 150 are forced to rotate in the same direction. At this time, the movable beam 230 is suspended in the air, and the membrane cloth 130 can fit closely to the movable beam 230. The movable beam 230 moves, thereby avoiding damage caused by friction between the membrane cloth 130 and the ground; in summary, the slidable design of the movable beam 230 can not only force the membrane cloth 130 to contact the ground under normal conditions to ensure the thermal insulation effect, but also can separate from the ground when the membrane cloth 130 moves to avoid membrane rupture; a connecting block 220 is slidably connected in the slideway 210, and the movable beam 230 can be rotatably connected to the connecting block 220; the movable beam 230 is rotated to connect the connecting block 220, so that the membrane cloth 130 can be moved when the membrane cloth 130 is in motion. When the movable beam 230 is in motion, the movable beam 230 is driven to rotate so as to reduce the friction between the membrane cloth 130 and the movable beam 230 during relative movement; a spring 240 is connected between the connecting block 220 and the slideway 210. Under normal circumstances, the spring 240 is in a compressed state and drives the movable beam 230 to contact the ground; the squeezing force of the spring 240 on the movable beam 230 is combined with the self-gravity of the movable beam 230, so as to ensure that the movable beam 230 can squeeze the membrane cloth 130 and contact the ground under normal circumstances, thereby ensuring the thermal insulation effect.

[0023] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
