Description

Technical Field

[0001] This invention relates to the field of swimming pool lining equipment technology, specifically an automatic heat preservation and moisture retention device for large swimming pools. Background Technology

[0002] With the improvement of living standards, swimming has become a popular and healthy form of exercise, and the number of heated pools is increasing. These heated pools are used during the day and are typically covered with a special swimming pool insulation film at night. This serves two purposes: firstly, to prevent dust from falling into the pool, keeping the water clean, reducing water evaporation, and mitigating the corrosive effects of water vapor on the swimming pool and equipment; secondly, to minimize the drop in pool water temperature, saving energy consumed during daytime heating and thus reducing operating costs. However, currently, the insulation film is stacked on one side of the pool during the day and manually pulled and covered at night, which is labor-intensive.

[0003] An existing patent application (application number 201520566585.3) describes an automatic covering device for a constant-temperature swimming pool insulation film. It includes a first gear, a first rack, a second gear, a second rack, a stainless steel tube, and an insulation film. The first and second gears are connected by the stainless steel tube. The first and second racks are arranged in parallel, and the first and second gears mesh with the first and second racks respectively. The insulation film is wound around the stainless steel tube, and in use, one end is fixed to one end of the swimming pool. The advantages of this invention are: the device has a simple structure and is easy to use; it saves space occupied by stacking insulation film during the day and greatly reduces the labor intensity of manually covering the insulation film, thus improving the level of modern pool management. However, it is not convenient to adjust the height of the covering roller, affecting the flexibility of the covering application. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic heat preservation and moisture retention device for large swimming pools, so as to solve the problem in the prior art that it is inconvenient to adjust the height of the coating roller, which affects the flexibility of coating application.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic heat preservation and moisture retention device for a large swimming pool, comprising a film-coated heat preservation base frame and a pusher. A film storage roller is rotatably mounted on the upper side of the film-coated heat preservation base frame via a vertical frame and a first rotating shaft. One end of the first rotating shaft is connected to a first motor via a gear set. A lifting slider is mounted on the inner wall of the vertical frame via a lead screw, and a lifting bracket is mounted between the two lifting sliders. A pressing roller, a film-coating roller, and an auxiliary traveling roller are mounted on the lower part of the lifting bracket. Push rollers are mounted at both ends of the film-coating roller, and a second rotating shaft at one end of the film-coating roller is connected to a second motor via a first belt flywheel set.

[0006] Furthermore, the leaf-covered insulation base is equipped with pulleys at the four corners on the lower side, and the pulleys are omnidirectional wheels.

[0007] Furthermore, the lead screw includes a lead screw rotatably disposed in a limiting slide groove on the side wall of the upright, and the lifting slider is threadedly connected to the lead screw, and a servo motor is drivenly connected to one end of the lead screw.

[0008] Furthermore, the outer diameter of the push roller is equal to the outer diameter of the coating roller, and the push roller is provided with anti-slip protrusions on its exterior.

[0009] Furthermore, the first motor is fixedly mounted on the outer wall of the support frame, and the second motor is fixedly mounted on the outer wall of the lifting bracket.

[0010] Furthermore, the pressing roller is disposed above the coating roller and the auxiliary traveling roller, and the upper side of the pressing roller is mounted on the top of the lifting bracket through a support frame and a cylinder.

[0011] Furthermore, the actuator includes a floating plate on the water surface. One end of the floating plate is equipped with a propeller that rotates through a connecting arm and a drive shaft. One end of the drive shaft is connected to a drive motor through a second belt flywheel assembly. The upper side of the floating plate is also equipped with a film end fixing bracket and a battery. The battery is electrically connected to the drive motor through wires and a switch. The upper part of the film end fixing bracket is equipped with a fixing bracket that slides longitudinally through a screw. The lower end of the fixing bracket is equipped with a positioning clamp, which can be adjusted by rotating the screw to raise and lower the positioning clamp, thereby facilitating the fixing of one end of the film to the floating plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This invention utilizes a film storage roller mounted on the upper side of a film-coated insulation base frame via a vertical frame and a first rotating shaft to store insulation film rolls. The inner wall of the vertical frame is equipped with a lifting slider and a lifting bracket via a lead screw. The lower part of the lifting bracket is equipped with a pressure roller, a film-coating roller, and an auxiliary traveling roller. One end of the insulation film is partially wrapped around the outside of the film-coating roller via the pressure roller. The film-coating roller is driven to rotate and move by a second motor and a first belt flywheel assembly to perform automatic film coating. The film coating efficiency is high, and the operation is convenient and quick.

[0014] 2. The present invention includes a lead screw that is rotatably installed in a limiting groove on the side wall of the upright frame, and the lifting slider is threadedly connected to the lead screw. One end of the lead screw is connected to a servo motor. Two sets of lead screws are arranged in parallel longitudinal directions, so that the lifting slider and the lifting bracket can be adjusted by the lead screw, thereby adjusting the working height of the coating roller and the auxiliary traveling roller. Moreover, when the coating roller and the auxiliary traveling roller are not in use, they can be moved upward and retracted into the lifting bracket, which improves the flexibility of coating use.

[0015] 3. In this invention, a pressing roller is set on the upper part of the coating roller and the auxiliary traveling roller, and the upper side of the pressing roller is installed in the top of the lifting bracket through a support frame and a cylinder. This allows the pressing roller to be pressed obliquely above the coating roller by the cylinder, which can press the heat-insulating and moisture-retaining film on the outside of the coating roller, thus improving the coating accuracy.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4In this embodiment of the invention, an automatic heat preservation and moisture retention device for a large swimming pool includes a film-coated heat preservation base frame 1 and a pusher. A film storage roller 4 is rotatably mounted on the upper side of the film-coated heat preservation base frame 1 via a stand 2 and a first rotating shaft 3 for storing heat preservation film rolls. One end of the first rotating shaft 3 is driven by a first motor 6 via a gear set 5, facilitating the unwinding of the film via the first motor 6 and the gear set 5. A lifting slider 9 is mounted on the inner wall of the stand 2 via a lead screw 8, and a lifting bracket 7 is mounted between the two lifting sliders 9. A pressing roller 20, a film-coating roller 11, and an auxiliary walking roller 17 are mounted on the lower part of the lifting bracket 7. Push rollers 12 are mounted at both ends of the film-coating roller 11, and a second rotating shaft 16 at one end of the film-coating roller 11 is driven by a second motor 14 via a first belt flywheel set 13. The first motor 6 is fixedly mounted on the outer wall of the stand 2, and the second motor 14 is fixedly mounted on the outer wall of the lifting bracket 7, so that the film-coated roller 11 can be rotated by the second motor 14 and the first belt flywheel set 13, enabling the film-coated heat preservation base frame 1 to move and automatically perform film coating.

[0024] like Figure 1 and Figure 2 As shown, in order to facilitate the overall movement and handling of the equipment, pulleys 15 are also provided at the four corners of the underside of the leaf-covered insulation base frame 1. The pulleys 15 are omnidirectional wheels, which facilitates the overall movement and handling of the equipment when it is not in use.

[0025] like Figure 1 and Figure 3 As shown, in order to adjust the working height of the coating roller 11, the lead screw 8 includes a lead screw rotatably disposed in the limiting slide groove 10 on the side wall of the upright frame 2, and the lifting slider 9 is threadedly connected to the lead screw. One end of the lead screw is connected to a servo motor. Two sets of lead screws are arranged in parallel longitudinally, so that the lifting slider 9 and the lifting bracket 7 can be driven to lift and adjust through the lead screw 8, thereby adjusting the working height of the coating roller 11 and the auxiliary traveling roller 17. Moreover, when the coating roller 11 and the auxiliary traveling roller 17 are not in use, they can be moved upward and retracted into the lifting bracket 7, which improves the flexibility of coating use.

[0026] like Figure 2 and Figure 3 As shown, in order to prevent slippage during the lamination process, the outer diameter of the push roller 12 is equal to the outer diameter of the lamination roller 11, and the push roller 12 is provided with anti-slip protrusions 18 on the outside, which increases the anti-slip properties of the outer sides of both ends of the lamination roller 11 and prevents slippage during the lamination process.

[0027] like Figure 1 and Figure 3As shown, in order to press the heat-insulating and moisture-retaining film tightly onto the outside of the coating roller 11, the pressing roller 20 is set on the upper part of the coating roller 11 and the auxiliary traveling roller 17. The upper side of the pressing roller 20 is installed on the top of the lifting bracket 7 through the support frame 19 and the cylinder 21, so that the pressing roller 20 is pressed on the outside of the coating roller 11 by the cylinder 21, which can press the heat-insulating and moisture-retaining film tightly onto the outside of the coating roller 11, thus improving the coating accuracy.

[0028] like Figure 4 As shown, in order to realize the film covering and film taking-up operations on the water surface, the propeller also includes a water surface suspension plate 22. One end of the water surface suspension plate 22 is rotatably equipped with a propeller 25 through a connecting arm 23 and a drive shaft 24. One end of the drive shaft 24 is connected to a drive motor 28 through a second belt flywheel assembly 27. The upper side of the water surface suspension plate 22 is also equipped with a film end fixing bracket 30 and a storage battery 29. The storage battery 29 is electrically connected to the drive motor 28 through wires and a switch, so that one end of the film is fixed on the water surface suspension plate 22. The drive motor 28 and the second belt flywheel assembly 27 drive the propeller 25 to rotate at a uniform speed, thereby enabling the film end to move on the water surface, thus realizing the film covering and film taking-up operations on the water surface.

[0029] like Figure 4 As shown, in order to fix one end of the membrane to the water surface suspension plate 22, a fixing bracket 31 is longitudinally slidably inserted into the upper part of the membrane end fixing bracket 30 through a screw 26. The lower end of the fixing bracket 31 is provided with a positioning clamp 32, so that the positioning clamp 32 can be raised and lowered by rotating the screw 26, thereby facilitating the fixing of one end of the membrane to the water surface suspension plate 22.

[0030] The working principle and usage process of this invention are as follows: When in use, the film to be kept warm and moist is wound around the film storage roller 4, and then one end of the heat-insulating film is pressed and partially wound around the outside of the coating roller 11 by the pressure roller 20. The film is unwound by the first motor 6 and the gear set 5, and at the same time, the coating roller 11 is driven to rotate and move by the second motor 14 and the first belt flywheel set 13 to perform automatic coating. The coating efficiency is high and the operation is convenient and quick.
