[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] Please refer to Figures 1-6 As shown in the figure, a solar large cell panel etching clean water circulation pipeline, including support seat 1, the upper portion of support seat 1 is provided with cleaning water tank 2, the bottom side of cleaning water tank 2 is provided with drain hole, the bottom port of drain hole is provided with pressure structure 8;

[0034] Transfer water tank 3, the bottom side of cleaning water tank 2 is provided with transfer water tank 3, the top of transfer water tank 3 is provided with output pump 4;

[0035] Filter structure 9, the bottom side of cleaning water tank 2 is provided with filter structure 9, the top of filter structure 9 is provided with pressure limiting structure 5;

[0036] Filter cylinder 94, the filter structure 9 includes filter cylinder 94, the filter cylinder 94 is fixed to the bottom side of cleaning water tank 2, the top inner cavity of filter cylinder 94 is provided with fixing seat 93, the fixing seat 93 is hollow structure, the bottom port of filter cylinder 94 is provided with sealing cover 91, the sealing cover 91 and fixing seat 93 are provided with filter element 92;

[0037] Communication cylinder 51, the pressure limiting structure 5 includes communication cylinder 51, the outer side of filter cylinder 94 is provided with communication cylinder 51, the inside of communication cylinder 51 is provided with second piston 57;

[0038] Movable rod 55, a movable rod 55 is movably disposed inside one end of the connecting cylinder 51, one end of the movable rod 55 is connected to one side of the second piston 57, a first electrode ring 52 is fixed to one side of the second piston 57, and a second electrode ring 53 is disposed on the inner wall of the connecting cylinder 51.

[0039] A limiting cap 54 is fixed to the other end of the movable rod 55. A second spring 56 is provided between the limiting cap 54 and the outer wall of the end face of the connecting cylinder 51. The second spring 56 is sleeved on the outside of the movable rod 55.

[0040] A second connecting pipe 58 is connected between the fixed base 93 and the connecting cylinder 51. A warning light 6 is installed on the outside of the cleaning water tank 2. The first electrode ring 52, the second electrode ring 53, the warning light 6 and the power supply are connected in series.

[0041] The filter cartridge 94 is connected to the transfer water tank 3 via a drain pipe 11, and the transfer water tank 3 is connected to the inlet of the output pump 4 via a pump pipe.

[0042] When texturing and cleaning the battery cells, the clean water used needs to be filtered and recycled. During the recycling process, it needs to be filtered through filter element 92. When filter element 92 is in operation for a long time, the filter holes become clogged, which can easily cause the filter pipe to burst due to pressure overload and also cause the pressure pump to burn out.

[0043] To ensure stable pipeline pressure during filtration, the water to be filtered is delivered to the filter cylinder 94 through the first connecting pipe 7. The filtered water is then introduced into the filter element 92. Since the inner cavity of the fixed seat 93 is connected to the inner cavity of the filter element 92, the pressure in the inner cavity of the fixed seat 93 is the same as the pressure in the inner cavity of the filter element 92 during filtration.

[0044] During filtration, water is filtered and discharged through filter element 92. As debris accumulates on the inner wall of filter element 92, the water flow rate decreases, leading to an increase in pressure inside filter element 92. Since the connecting cylinder 51 and the fixed base 93 are connected through the second connecting pipe 58, the pressure inside the connecting cylinder 51 is the same as the pressure inside filter element 92. When the pressure inside filter element 92 increases, it can push the second piston 57 to move. When the pressure inside the cavity is overloaded, the second piston 57 is squeezed, and the first electrode ring 52 and the second electrode ring 53 come into contact, causing the warning light 6 to be powered on and flash. When the warning light 6 flashes, it indicates that filter element 92 can be replaced and maintained to ensure the filtration effect of water circulation and to prevent pipe bursts by ensuring normal pipeline pressure.

[0045] When the pressure inside the filter core 92 increases, the second piston 57 moves to achieve a stretching movement of the second spring 56, and when the second spring 56 returns after filtration, the second piston 57 can be pushed back to reset. The communication barrel 51 provided with an adjustable activity space can buffer the pressure inside the filter core 92 and better protect the filtering structure.

[0046] The pressurizing structure 8 comprises a pressurizing barrel 81 fixed at the bottom side of the cleaning water tank 2, a flow resistance plate 82 provided on the upper inner wall of the pressurizing barrel 81, a guide hole provided at the middle position of the flow resistance plate 82, a first piston 85 movably arranged in the pressurizing barrel 81, a limiting tube 84 vertically fixed at the middle position of the first piston 85, a plug rod 810 movably inserted into the limiting tube 84, a first spring 89 fixed between the plug rod 810 and the bottom inner wall of the limiting tube 84, and a blocking cap 83 fixed at the top of the plug rod 810.

[0047] A sliding groove 811 is formed in the side inner wall of the pressurizing barrel 81, and a sliding rod 812 is fixed at the top side of the plug rod 810 and slidably arranged in the sliding groove 811.

[0048] A pushing motor 87 is mounted at the top side of the support base 1, a rotating disc 86 is mounted on the output shaft of the pushing motor 87, a push rod 88 is connected to the end face of the rotating disc 86 at an eccentric position, and the top end of the push rod 88 is rotatably connected to the bottom end of the limiting tube 84. When the solar cell panel is cleaned, the cleaned water needs to be circulated, and the waste water needs to be pressurized and delivered during the circulation process.

[0049] When the push rod 88 is at the lowest position and the limiting tube 84 moves downward under the cooperation of the rotating disc 86, the plug rod 810 moves downward, the blocking cap 83 is separated from the guide hole in the middle of the flow resistance plate 82, the waste water enters the middle of the pressurizing barrel 81 through the guide hole, and when the rotating disc 86 continues to move, the push rod 88 is pushed upward and the limiting tube 84 is pushed upward. When the limiting tube 84 is pushed upward for a stage, the blocking cap 83 blocks the guide hole in the flow resistance plate 82.

[0050] When the guide hole is indexed, the first piston 85 is pushed upward when the limiting tube 84 moves upward, and the first spring 89 is squeezed. When the first piston 85 is pushed upward, the waste water in the pressurizing barrel 81 is pressurized and discharged through the first connecting pipe 7, realizing the pressurized delivery of the waste water.

[0051] Through pressurized delivery, the flow speed of the waste water can be accelerated, the accumulation of impurities in the first connecting pipe 7 can be avoided, and the waste water filtering operation can be cooperated.

[0052] One end of the first connecting pipe 7 is connected to the middle part of the pressurizing cylinder 81, and the other end of the first connecting pipe 7 is rotationally connected to the middle part of the sealing cover 91.

[0053] The bottom of the cleaning water tank 2 is connected with a drain pipe, and the top of the intermediate water tank 3 is provided with an air hole, which can facilitate the complete discharge of the waste water and the discharge of the water in the intermediate water tank 3.

[0054] The working principle is that by pushing the motor 87 to move, under the operation of the rotating disc 86, when the push rod 88 is at the lowest position, the limiting pipe 84 is driven to move downward, the plug rod 810 moves downward, the blocking cap 83 is separated from the flow guide hole in the middle part of the flow resistance plate 82, the waste water enters the middle part of the pressurizing cylinder 81 through the flow guide hole, and when the rotating disc 86 continues to move, the push rod 88 is pushed up, the limiting pipe 84 is pushed up, and when the limiting pipe 84 is pushed up for a stage, the blocking cap 83 blocks the flow guide hole in the flow resistance plate 82;

[0055] When the flow guide hole is indexed, the large first piston 85 is pushed up while the first spring 89 is extruded when the limiting pipe 84 is subsequently moved upward, the waste water in the pressurizing cylinder 81 is pressurized and discharged through the first connecting pipe 7 when the first piston 85 is pushed upward, and the pressurized delivery of the waste water is realized;

[0056] The filtered water is delivered to the filter cylinder 94 through the first connecting pipe 7, and the filtered water enters the filter element 92, and because the inner cavity of the fixed seat 93 is communicated with the inner cavity of the filter element 92, the pressure in the inner cavity of the fixed seat 93 is the same as the pressure in the inner cavity of the filter element 92 during filtration;

[0057] During filtration, the water is filtered and discharged through the filter element 92, and as the impurities accumulate on the inner wall of the filter element 92, the water passing speed decreases, causing the pressure in the inner cavity of the filter element 92 to increase, and because the communication cylinder 51 and the fixed seat 93 are communicated through the second connecting pipe 58, the pressure in the communication cylinder 51 is the same as the pressure in the inner cavity of the filter element 92, and when the pressure in the inner cavity of the filter element 92 increases, the second piston 57 is pushed to move, and when the inner cavity pressure is overloaded, the first electrode ring 52 and the second electrode ring 53 are in contact after the second piston 57 is extruded, causing the warning light 6 to flash, and when the warning light 6 flashes, it indicates that the filter element 92 can be replaced and maintained to ensure the filtering effect of the water circulation and to avoid pipe explosion by ensuring normal pipe pressure.
