[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figures 1-5 The rain test platform for a flat-plate solar collector shown includes a base plate 1, a collection pool 2 fixedly installed on the top of the base plate 1, a fixing component for fixing the flat-plate solar collector is installed inside the collection pool 2, and a limit cover 6 is raised and lowered directly above the collection pool 2. The limit cover 6 is connected to the base plate 1 through the lifting component.

[0018] The fixing components include a hollow placement platform 9, which is inclined. Support rods 8 are fixedly installed at the four corners of the bottom of the hollow placement platform 9, and the support rods 8 are fixedly connected to the collection pool 2. Fixing rods 11 are fixedly installed on all four sides of the hollow placement platform 9. A first sliding groove 12 is formed inside the fixing rod 11, and a movable rod 13 is slidably installed inside the first sliding groove 12. Limiting grooves 14 are formed on both sides of the first sliding groove 12, and a fixing shaft 15 is fixedly installed inside the limiting groove 14. A limiting block 16 is slidably installed on the outer circumference of the fixing shaft 15. The movable rod 13 is fixedly connected to the limit block 16. Springs 17 are fixedly installed on both sides of the limit block 16. The other end of the spring 17 is fixedly connected to the inner wall of the limit groove 14. The spring 17 is movably sleeved on the outer ring of the fixed shaft 15. An L-shaped clamping block 19 is installed inside the movable rod 13 through the adjustment component. The L-shaped clamping block 19 fits against the side of the flat plate solar collector. A rope 18 is fixedly installed at the end of the movable rod 13. A rotating shaft is rotatably installed in the middle of the hollow placement platform 9. The other end of the rope 18 extends into the interior of the hollow placement platform 9 and is fixedly connected to the rotating shaft.

[0019] The hollow placement platform 9 is equipped with a power assembly at its bottom. The power assembly includes a housing 10, which is fixedly installed in the middle of the bottom of the hollow placement platform 9. A motor is fixedly installed inside the housing 10, and the output end of the motor extends into the interior of the hollow placement platform 9 and is fixedly connected to the rotating shaft.

[0020] The adjustment component includes a second slide groove, which is located inside the movable rod 13. An L-shaped clamping block 19 is slidably disposed inside the second slide groove. An adjustment groove is provided inside the L-shaped clamping block 19. A movable plate is movably engaged at the bottom of the second slide groove. A bolt 20 is fixedly disposed at the top of the movable plate. A nut 21 is threadedly connected to one end of the bolt 20 that moves through the adjustment groove.

[0021] Specifically, in the process of using this utility model, after placing the flat-plate solar collector on the hollow placement platform 9, the motor is started, driving the rotating shaft to rotate, and then the rope 18 is wound around the rotating shaft, causing the four movable rods 13 to move synchronously, and then the four L-shaped clamping blocks 19 to move synchronously, clamping the flat-plate solar collector on the hollow placement platform 9. After the test is completed, the motor is started in reverse. At this time, the spring 17 restores its elasticity, driving the movable rods 13 to reset, and then driving the L-shaped clamping blocks 19 to move, releasing the flat-plate solar collector, thus facilitating the fixing and disassembly of the flat-plate solar collector.

[0022] When the flat-plate solar collectors are of different models, turn the nut 21 to loosen the L-shaped clamping block 19, push the L-shaped clamping block 19 to move inside the second slide groove, and at the same time push the movable plate and bolt 20 to move. After moving to the appropriate position, tighten the nut 21 to fix the L-shaped clamping block 19 and the movable rod 13, so as to fix flat-plate solar collectors of different models and sizes.

[0023] In summary, this utility model improves the efficiency of fixing and disassembling flat-plate solar collectors by installing fixing and adjusting components, and can fix flat-plate solar collectors of different sizes and models. It solves the problem that existing solar collector rain test devices are inconvenient to fix and disassemble flat-plate solar collectors of different sizes and models during use, which reduces the convenience of the device.

[0024] Furthermore, the lifting assembly includes two symmetrically distributed columns 3, with lifting grooves inside the columns 3.

[0025] Furthermore, a number of evenly distributed nozzles are fixedly installed on the inner wall of the top of the limiting cover 6, and a water inlet pipe 7 is fixedly installed on the side of the limiting cover 6. The water inlet pipe 7 is connected to the nozzles through branch pipes.

[0026] Specifically, after fixing the flat-plate solar collector, the hydraulic cylinder 4 is activated, causing the limiting cover 6 to move downwards, so that the limiting cover 6 covers the outside of the flat-plate solar collector. Water is then supplied to the water inlet pipe 7 and sprayed onto the flat-plate solar collector through the nozzle for a rain test. Under the restriction of the limiting cover 6, all the water falls into the inside of the collection tank 2 for collection. Since the side of the collection tank 2 is fixedly equipped with a drain pipe 22, the water is finally discharged from the drain pipe 22 and can be recycled, improving the practicality of the device.

[0027] Furthermore, the upper surfaces of the hollow placement platform 9, the fixed rod 11, and the movable rod 13 are all on the same plane. This arrangement ensures that the hollow placement platform 9, the fixed rod 11, and the movable rod 13 can all support the flat plate solar collector, guaranteeing the stability of the flat plate solar collector.

[0028] Working Principle: In use, after placing the flat-plate solar collector on the hollow placement platform 9, the motor is started, driving the rotating shaft to rotate. This causes the rope 18 to be wound around the rotating shaft, causing the four movable rods 13 to move synchronously. Consequently, the four L-shaped clamping blocks 19 move synchronously, clamping the flat-plate solar collector onto the hollow placement platform 9. The hydraulic cylinder 4 is then activated, causing the limiting cover 6 to move downwards, covering the outside of the flat-plate solar collector. Water is supplied through the inlet pipe 7 and sprayed onto the flat-plate solar collector through nozzles for a rain test. Under the constraint of the limiting cover 6, all the water falls into the collection tank 2 for collection. Since a drain pipe 22 is fixedly installed on the side of the collection tank 2, the water... The contents are then discharged through drain pipe 22 and can be recycled. After the test is completed, the limit cover 6 is reset and the motor is started in reverse. At this time, the spring 17 recovers its elasticity, drives the movable rod 13 to reset, and then drives the L-shaped clamping block 19 to move, loosening the flat plate solar collector, which facilitates the disassembly of the flat plate solar collector. When the flat plate solar collector is of different models, turn the nut 21 to loosen the L-shaped clamping block 19, push the L-shaped clamping block 19 to move inside the second slide groove, and at the same time push the movable plate and bolt 20 to move. After moving to the appropriate position, tighten the nut 21 to fix the L-shaped clamping block 19 and the movable rod 13, so as to fix flat plate solar collectors of different models and sizes.

[0029] The wiring diagrams of the hydraulic cylinder 4 and the motor in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the hydraulic cylinder 4 and the motor will not be explained in detail.
