[0037] Reference Figure 4The driving mechanism 2 includes a mounting seat 202, which is fixedly connected to the top outer wall of the outer wall 1. The driving mechanism 2 can be fixed to the top of the outer wall 1 through the mounting seat 202. A groove 204 is opened on the inner wall of the mounting seat 202. The groove 204 is provided with three groups, and corresponds to the three groups of protrusions 306 on the slide bar 302 respectively. The top outer wall of the mounting seat 202 is fixedly connected to the motor 201, and the output shaft of the motor 201 is fixedly connected to the pulley A203. When the motor 201 is started, the output shaft of the motor 201 rotates and drives the pulley A203 to rotate synchronously.
[0038] Reference Figure 4 The outer wall of the pulley A203 is connected to the pulley B301 through a belt drive. When the pulley A203 rotates, the pulley B301 can be driven to rotate synchronously through the belt. The outer wall of the mounting seat 202 is provided with a transmission component, and the sleeve rod 307 can be driven to rotate through the transmission component, so that the thermal insulation quilt 401, the ventilation membrane 402 and the thermal insulation film 403 can be rolled up or unfolded for use.

[0039] Reference Figure 4-Figure 6 The transmission assembly includes a pulley B301, and the inner wall of the pulley B301 is provided with multiple groups of slide grooves A305. The protrusion 306 can be engaged with the inner wall of the slide groove A305 to drive the corresponding slide bar 302 to rotate through the pulley B301. The outer wall of the pulley B301 is connected with a pulley C309 through a belt transmission. The pulleys B301 and C309 are both rotatably connected to the outer wall of the mounting seat 202.

The slide groove B308 contacts the outer wall of the protrusion 306, so that when the pulley C309 rotates, the corresponding slide bar 302 can be driven to rotate.
[0040] Reference Figure 4-Figure 6The inner wall of the mounting seat 202 contacts with a slide bar 302, and the slide bar 302 can rotate on the inner wall of the mounting seat 202 and move horizontally left and right. The inner walls of the pulleys B301 and C309 are in contact with the outer wall of the slide bar 302. When the protrusion 306 contacts the inner walls of the slide grooves A305 and B308, the pulleys B301 and C309 can drive the slide bar 302 to rotate synchronously, and the protrusion 306 is disengaged from the slide grooves A305 and B308 by moving the slide bar 302 horizontally, so that the pulleys B301 and C309 cannot drive the slide bar 302 to rotate. The outer wall of the slide bar 302 is rotatably connected with a rotating block 303. When the slide bar 302 rotates, the rotating block 303 can limit the slide bar 302, so that the slide bar 302 cannot move horizontally, but can still rotate.
[0041] Reference Figure 4-Figure 6 The outer walls of the slide bar 302 and the rotating block 303 are both provided with a slot 304. When the limit block 503 is engaged with the slot 304 on the slide bar 302, the slide bar 302 cannot rotate, and when the limit block 503 is engaged with the slot 304 on the rotating block 303, the rotating block 303 cannot rotate, and the slide bar 302 can be driven to rotate by the pulley B301 or the pulley C309, and the slide bar 302 is limited so that the slide bar 302 cannot move laterally. The top outer wall of the slide bar 302 is fixedly connected with a protrusion 306, and the protrusion 306 is provided with three groups, and each group of slide bars 302 is provided with a group of protrusions 306. The protrusions 306 on the upper two groups of slide bars 302 can be engaged with the slide groove A305, and the protrusions 306 on the lower group of slide bars 302 can be engaged with the slide groove B308, and each group of protrusions 306 can be engaged with the groove 204.
[0042] Reference Figure 4-Figure 6 The outer wall of the slide bar 302 is slidably connected with a sleeve rod 307, a block is provided on the top outer wall of the slide bar 302, a square groove is provided on the inner wall of the sleeve rod 307, the block is kept in contact with the inner wall of the square groove, the right side of the sleeve rod 307 is rotatably connected with the top outer wall of the outer wall 1, and the sleeve rod 307 can be driven to rotate synchronously when the slide bar 302 rotates through the contact between the block and the inner wall of the square groove. The sleeve rod 307 is provided with three groups, and the outer wall of the first group of sleeve rods 307 is fixedly connected with a heat preservation quilt 401, and the heat preservation quilt 401 is provided on the topmost group of sleeve rods 307 The thermal insulation quilt 401 can keep the inside of the greenhouse warm, and sunlight cannot enter the greenhouse after the thermal insulation quilt 401 is unfolded. The outer wall of the second set of sleeve rods 307 is fixedly connected with a ventilation membrane 402, and the ventilation membrane 402 is arranged on the middle set of sleeve rods 307, and has multiple sets of ventilation holes, which can achieve better ventilation effect. The outer wall of the third set of sleeve rods 307 is fixedly connected with a thermal insulation film 403, and the thermal insulation film 403 is arranged on the bottom set of sleeve rods 307, which can allow sunlight to enter the greenhouse and also achieve a certain thermal insulation effect.
[0043] Reference Figure 7 The limit assembly includes a fixed block 501, which is fixedly connected to the left outer wall of the mounting seat 202. The inner wall of the fixed block 501 is elastically connected to the limit block 503 through a spring 502. The limit block 503 is engaged with the card slot 304, and the slide bar 302 can be limited. One end of the spring 502 is fixedly connected to the outer wall of the limit block 503, and the other end of the spring 502 is fixedly connected to the inner wall of the fixed block 501. When the limit block 503 corresponds to the position of the card slot 304, Due to its own elastic force, the spring 502 can drive the limit block 503 to pop out and engage with the slot 304, so that the slide bar 302 can be limited. The outer wall of the limit block 503 is slidably connected to the inner wall of the fixed block 501, and the limit block 503 is engaged with the slot 304. The outer wall of the limit block 503 is fixedly connected with a pull rod 504. By pulling the pull rod 504 outward, the limit block 503 can be disengaged from the slot 304, so that the limit of the slide bar 302 can be released and the slide bar 302 can be moved.
[0044] Working principle: The device can be fixed in soft soil through the cone tube 8, and the greenhouse is supported and fixed by multiple sets of steel structures 7. When the insulation quilt 401, ventilation membrane 402 or insulation membrane 403 needs to be used, the operator can go up to the top of the outer wall 1 through the ladder 6. When the ventilation membrane 402 needs to be unfolded for use, the operator can pull out the upper and lower pull rods 504 to disengage the limit block 503 from the slot 304 on the rotating block 303, and move the upper and lower pull rods 504 to the upper and lower pull rods 504. The two groups of slide bars 302 are pulled outward. When the slide bars 302 are pulled out to the position corresponding to the slot 304 and the limit block 503, the elastic force of the spring 502 drives the limit block 503 to pop out and engage with the slot 304, so that the position of the slide bars 302 can be fixed. During this process, the protrusions 306 on the two groups of slide bars 302 are out of contact with the slots A305 and B308 in the top group of pulleys B301, and contact with the inner wall of the groove 204, thereby limiting the slide bars 302.
[0045] At this time, the motor 201 can be started, so that the motor 201 drives the two sets of pulleys B301 and the pulley C309 to rotate through the pulley A203. Since the protrusions 306 on the upper and lower sets of slide bars 302 are out of contact with the corresponding slide grooves A305 and B308, the upper and lower pulleys B301 and the pulley C309 cannot drive the corresponding slide bars 302 to rotate. Only the middle set of pulleys B301 can drive the middle slide bar 302 to rotate, and when the slide bar 302 rotates, the sleeve rod 307 can be driven to rotate synchronously, so that the ventilation membrane 402 on the sleeve rod 307 is unfolded and can be used. Moreover, since there are multiple sets of ventilation holes on the ventilation membrane 402, the ventilation effect is improved. When the ventilation membrane 402 needs to be folded, the motor 201 can be reversed, and the ventilation membrane 402 can be folded by rotating the sleeve rod 307.
[0046] To sum up, when a certain group of thermal insulation quilts 401, ventilation membranes 402 or thermal insulation films 403 needs to be used, it is only necessary to release the limit of the other two groups of slide bars 302, pull the other two groups of slide bars 302 outward, and make the protrusions 306 on the two groups of slide bars 302 contact with the grooves 204, so that the slide bars 302 can be limited, so that the slide bars 302 cannot drive the sleeve rods 307 to rotate, thereby a certain group of thermal insulation quilts 401, ventilation membranes 402 or thermal insulation films 403 can be rolled up or unfolded for use, and this operation only requires one set of motors 201 to complete, which is more cost-effective.
[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
