[0031] The following will further describe the present application in detail with reference to the Figure 1-6 accompanying drawings.

[0032] An embodiment of the present application discloses an automatic retractable plastic covering device for a salt pond.

[0033] Referring to Figure 1 and Figure 2 , the automatic retractable plastic covering device for a salt pond includes a hanging track 4, a film covering device 1, and a traction device 3. The hanging track 4 is arranged in parallel on both sides of the salt pond and is used for guiding the film material 2. The film covering device 1 is arranged at one end of the hanging track 4. The film covering device 1 includes a floating drum 101 and a film covering motor 103. The floating drum 101 is used for winding the film material. The film covering motor 103 drives the floating drum 101 to rotate to retract and release the film material 2. The traction device 3 is arranged at the end of the hanging track far from the film covering device 1 and includes a traction rod 301, a traction rope 302, a winch 303, and a traction motor 304. The traction rope 302 is wound around the winch 303 and is connected to the traction rod 301. The traction rod 301 is connected to the end of the film material 2. The traction motor 304 drives the winch 303 to rotate to make the winch 303 retract and release the traction rope 302, so as to drive the traction rod 301 to move.

[0034] Referring to Figure 2 and Figure 4, The hanging track 4 is arranged in parallel on both sides of the salt pond and fixed to the side wall of the salt pond. The hanging rope is fixed and guided through the hanging column and the guide plate, which is used to guide the membrane material 2 to ensure that the membrane material 2 remains stable during the winding and unwinding process and does not deviate from the track. The film covering device 1 is installed at one end of the salt pond and is arranged close to the concrete foundation 7. The film covering device 1 includes a floating drum 101 and a film covering motor 103. The floating drum 101 is used for winding the membrane material 2 and can rotate to wind and unwind the membrane material 2 during the film covering and film winding processes. The film covering motor 103 drives the floating drum 101 to rotate to control the winding and unwinding of the membrane material 2. The floating drum 101 and the film covering motor 103 work together to realize the automatic winding and unwinding of the membrane material 2, ensuring that the membrane material 2 unfolds smoothly during the film covering process and is tightly wound during the film winding process. The traction device 3 includes a traction rod 301, a traction rope 302, a winch 303, and a traction motor 304. The traction rod 301 is connected to the end of the membrane material 2 to traction the membrane material 2 to move on the track. The traction rope 302 is connected to the traction rod 301 and the winch 303. The winch 303 winds and unwinds the traction rope 302 to drive the traction rod 301 to move. The winch 303 drives the winding and unwinding of the traction rope 302 to control the movement of the traction rod 301. The traction motor 304 drives the winch 303 to rotate to control the winding and unwinding of the traction rope 302. The traction device 3 drives the membrane material 2 to move along the hanging track 4 through the movement of the traction rod 301 and the traction rope 302, realizing the film covering and film winding operations. The functions and advantages of this equipment include realizing automatic film covering and film winding, eliminating manual operation, improving the operation efficiency and safety, remote real-time monitoring and control, realizing synchronous film covering of multiple salt fields, reducing the workload and labor intensity of personnel, realizing the automatic winding and unwinding of the membrane material 2 through the floating drum 101 and the film covering motor 103, and the winch 303 and the traction motor 304 control the movement of the traction rod 301 to ensure the continuity and stability of the film covering and film winding processes

[0035] Refer to Figure 3 , The membrane material 2 is composed of a PVC membrane 201 and a membrane edge hanging rope 202. A rope arranging device 102 is arranged on the floating drum 101, and the membrane edge hanging ropes 202 are arranged on the rope arranging device 102. The membrane edge hanging ropes 202 are wound around the side of the membrane material 2 in the form of a thread package. The rope arranging device 102 arranges the membrane edge hanging ropes 202 on the floating drum 101 and winds the hanging ropes around the side of the membrane material 2 in the form of a thread package. In this way, during the winding and unwinding process of the membrane material 2, the rope arranging device 102 can ensure the uniform arrangement of the hanging ropes, prevent the hanging ropes from being wound or knotted, and thus ensure the smooth and unobstructed winding and unwinding of the membrane material 2. The function of this technical feature is that through the uniform arrangement of the rope arranging device 102 and the winding of the hanging ropes in the form of a thread package, the smooth progress of the membrane material 2 during the winding and unwinding process is ensured, the possible winding problem of the hanging ropes during the winding and unwinding process is avoided, the operation stability and reliability of the equipment are improved, and the film covering and film winding processes are made more efficient and automated

[0036] Refer to Figure 5, the hanging track 4 includes hanging columns 401, guide plates 402 and hanging ropes 404. The hanging columns are used to be fixed on the side wall of the salt pond. A plurality of hanging columns are arranged at intervals along the hanging ropes. The guide plates are fixed on the hanging columns. The hanging ropes are movably threaded through the guide plates. One end of the hanging rope is connected to the film edge hanging rope 202. The hanging columns are arranged at intervals along the side wall of the salt pond to provide a support structure. The guide plates are fixed on the hanging columns. The hanging ropes are threaded through the guide holes of the guide plates and fixed in place. One end of the hanging rope is connected to the film edge hanging rope 202. During the film covering and film retracting processes, by the pulling of the traction device 3, the film material 2 moves smoothly along the hanging track 4. Through the arrangement of the hanging columns and the guide plates, the hanging ropes can provide stable guiding and support, ensuring the smooth operation of the film material 2 during the retracting and releasing processes, preventing the film material 2 from shifting or wrinkling during the movement, thus ensuring the smooth progress of the film covering process and improving the efficiency and accuracy of the film covering and film retracting operations.

[0037] Refer to Figure 5 , a guide tube 403 parallel to the hanging rope is fixed on the guide plate 402. The guide tubes are arranged on the left and right sides of the hanging rope respectively. A guide groove for guiding the film material 2 is formed between the two guide tubes on both sides. By arranging two parallel guide tubes on the guide plate, one on the left side of the hanging rope and one on the right side, when the hanging rope is threaded through the guide plate, the guide tubes can form a stable guide groove, so that the film material 2 always remains in the guide groove during the retracting and releasing processes and will not deviate from the track. Through this design, the film material 2 can be effectively guided and supported during the movement, ensuring the smooth operation of the film material 2, preventing deviation, wrinkling or damage during the movement, thus ensuring the smooth progress of the film covering and film retracting operations and improving the operation stability and efficiency of the whole system.

[0038] The film covering device 1 further includes a motor counterweight frame 104. The film covering motor 103 is installed on the motor counterweight frame 104 to keep the film covering motor 103 floating on the water surface. The motor counterweight frame 104 is designed to be able to float on the water surface. In this way, during the film covering operation, both the film covering motor 103 and the floating drum 101 can maintain a stable floating state and are not affected by the fluctuations of the water surface. The film covering motor 103 drives the floating drum 101 to rotate to retract and release the film material 2. The buoyancy of the counterweight frame ensures that the motor and the floating drum 101 always remain above the water surface, thus avoiding the problems of equipment water ingress or tilting. Through this design, the film covering motor 103 and the floating drum 101 can remain stable during operation, ensuring that the film material 2 is smoothly unwound and wound during the film covering and film retracting processes and will not cause film covering quality problems due to the instability of the equipment. At the same time, the design of the motor counterweight frame 104 floating on the water surface makes the overall operation of the equipment more flexible and reliable, improving the operation efficiency and service life of the equipment

[0039] Refer to Figure 6, the automatic retractable plastic covering equipment for the salt pond further includes a drainage device 5 arranged at the drainage outlets at the four corners of the salt pond. The drainage device 5 includes a support frame 501, a lifting screw rod 502, and a drainage box 503. The support frame 501 is used to be fixed above the drainage outlet. The lifting screw rod 502 is installed on the support frame 501 and is used to drive the drainage box 503 to lift and lower. A drainage channel is provided on the drainage box 503. By arranging the drainage device 5 at the four corners of the salt pond, the support frame 501 is fixed above the drainage outlet, the lifting screw rod 502 is installed on the support frame 501, and the drainage box 503 is driven to perform lifting and lowering operations. A drainage channel is provided on the drainage box 503. When drainage is required, the height of the drainage box 503 can be adjusted by the lifting and lowering operation of the screw rod, so that the drainage channel of the drainage box 503 enters or exits the water surface. By driving the lifting and lowering of the drainage box 503 through the lifting screw rod 502, the height of the drainage channel of the drainage box 503 can be flexibly controlled, thereby achieving precise drainage control. After the film covering operation is completed, the drainage box 503 can be lowered to sink its drainage channel into the water to achieve automatic drainage, ensuring that the accumulated water on the film material 2 can be smoothly discharged, preventing water from accumulating on the film material 2 and affecting the subsequent operation.

[0040] A rope receiving track 506 is provided on the support frame 501. A free guiding plate 504 is slidably arranged in the rope receiving track 506. A guiding hole for the hanging rope to pass through is provided on the free guiding plate 504. By providing a rope receiving track 506 on the support frame 501, a free guiding plate 504 is slidably arranged in the track, and a guiding hole for the hanging rope to pass through is provided on the free guiding plate 504. During the operation, the hanging rope passes through the guiding hole of the free guiding plate 504, and the position and tension of the hanging rope can be flexibly adjusted through the sliding free guiding plate 504.

[0041] The rope receiving tracks 506 are symmetrically arranged on both sides of the drainage box 503. By symmetrically arranging the rope receiving tracks 506, the hanging ropes are evenly distributed on both sides of the drainage box 503, ensuring the balance and stability of the film material 2 during the retracting and extending process, preventing the film material 2 from tilting, shifting, or unevenly stressed during the operation, thereby improving the efficiency and quality of film covering and film retracting.

[0042] A clamping device is provided on the drainage box 503. The clamping device includes a fixed baffle, a movable baffle, and a driving component. A clamping space for the plastic covering film to pass through is formed between the fixed baffle and the movable baffle. The driving component is used to drive the movable baffle to approach the fixed baffle to clamp the plastic covering film.

[0043] The driving component includes a slider, a first pull rod, a second pull rod, and a buoyancy plate. A chute is provided horizontally at the bottom of the drainage tank 503. The slider is fixedly connected to the movable baffle and slidably arranged in the chute. One end of the first pull rod is hinged to the slider, and the other end is hinged to the buoyancy plate. One end of the second pull rod is fixed in the chute, and the other end is hinged to the buoyancy plate. The buoyancy plate rises or falls in water under the action of buoyancy, driving the first pull rod and the second pull rod to move. Specifically, when the water level rises, the buoyancy plate rises under the action of buoyancy, and the linkage of the first pull rod and the second pull rod pushes the slider to slide in the chute, thereby driving the movable baffle closer to the fixed baffle to clamp the plastic covering film. When the water level drops, the buoyancy plate descends, pulling the first pull rod and the second pull rod, and the slider slides reversely in the chute, and the movable baffle separates from the fixed baffle to release the clamped plastic covering film. The function of this design is to automatically control the opening and closing of the clamping device by using the buoyancy of water to achieve automatic operation. Through the rise and fall of the buoyancy plate, the position of the movable baffle can be flexibly adjusted to ensure that the plastic covering film can be firmly clamped during the drainage process, avoiding loosening and displacement, and improving the drainage efficiency. At the same time, this design reduces the dependence on electricity and complex mechanical structures, realizes automatic operation through simple physical principles, reduces the maintenance cost and failure rate of the equipment, and improves the reliability and operation convenience of the overall system.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
