[0024] In specific implementation, the solar collector has a high light energy absorption rate and good heat transfer performance, but the tempered glass 2 on the surface of the solar collector is easy to get dirty, and it is troublesome for personnel to clean it. Therefore, the knob 13 can be loosened, and the scraper 15 can be pulled or pushed. When the bottom of the scraper 15 is at a specified position away from the surface of the tempered glass 2, the knob 13 can be tightened. When the knob 13 is tightened, the scraper 15 can be squeezed and limited. At this time, the motor 9 can be started. When the motor 9 is running, the stainless steel threaded rod 8 can be driven to rotate. When the stainless steel threaded rod 8 rotates, it can drive the first slider 1 0 performs threaded sliding. When the first slider 10 threadedly slides, it can drive the moving block 11 to move. When the moving block 11 moves, it can drive the second slider 12 to move. When the second slider 12 moves, it can slide through the connecting block 6. When the moving block 11 moves, it can drive the scraper 15 and the cleaning cloth block 14 to move. At this time, the scraper 15 can scrape the foreign matter on the surface of the tempered glass 2, and the cleaning cloth block 14 can clean the scraped position. When the foreign matter on the surface of the tempered glass 2 is cleaned, the personnel can sweep the foreign matter on the surface of the tempered glass 2 away.
[0025] See also Figure 1 , Figure 2 and Figure 3 It can be seen that, through this simple and convenient method, foreign objects on the surface of the tempered glass 2 can be quickly cleaned, so that when cleaning foreign objects on the surface of the tempered glass 2, personnel do not need to work at height for a long time, thereby reducing the workload of personnel.
[0026] See also Figure 1 , Figure 2 , Figure 4 and Figure 5It can be seen that mounting blocks 16 are installed at both ends of the outer frame body 1, a rotating groove 17 is opened inside the mounting block 16, a fixing rod 18 is installed inside the mounting block 16, a clamping block 19 is movably connected to the outer side of the fixing rod 18, a spring 20 is connected between the clamping block 19 and the mounting block 16, a lever 21 is connected to the outer side of the clamping block 19, a connecting column 22 is welded on the top of the mounting frame 5, and a rotating structure is formed between the clamping block 19 and the fixing rod 18.
[0027] In specific implementation, during the installation of the solar collector panel, the four corners of the outer frame body 1 need to be placed on the mounting frame 5 and fixed with screws using tools. This fixing method is relatively time-consuming. For this purpose, the two sets of levers 21 can be pushed toward each other. When the lever 21 moves, the block 19 can be driven to move. When the block 19 moves, it can be rotated by the fixing rod 18. When the block 19 rotates, the spring 20 can be stretched. When the spring 20 is stretched to a specified degree, the outer frame body 1 can be placed on the surface of the mounting frame 5. At this time, the connecting column 22 can pass through the mounting block 16, so that the two sets of levers 21 can be loosened. When the lever 21 is loosened, the block 19 can be reset by the spring 20. When the block 19 is reset, its end can move to the inside of the connecting column 22. At this time, the outer frame body 1 can be quickly installed on the surface of the mounting frame 5.
[0028] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be seen that the outer frame body 1 can be quickly installed and fixed through this simple and convenient method, thereby improving the installation efficiency.
[0029] In summary, when the water-circulating solar thermal collector is used in an agricultural greenhouse, when sunlight irradiates the tempered glass 2, the heat collector body 3 can absorb the heat energy generated by the sunlight and transfer the absorbed heat energy to the water inside the water pipe 4, thereby heating the water, and transporting the heated water to the water storage tank in the greenhouse. In this way, the temperature inside the greenhouse can be changed, thereby accelerating the growth of crops. The water-circulating solar thermal collector is a prior art and will not be described in detail here. When the foreign matter on the surface of the tempered glass 2 is cleaned up, the personnel can remove the tempered glass. Foreign objects on the surface of the tempered glass 2 can be swept off. Through this simple and convenient method, foreign objects on the surface of the tempered glass 2 can be quickly cleaned, so that when personnel clean foreign objects on the surface of the tempered glass 2, there is no need to perform long-term high-altitude operations, thereby reducing the workload of personnel. When the block 19 is reset, its end can be moved to the inside of the connecting column 22. At this time, the outer frame body 1 can be quickly installed on the surface of the mounting frame 5. Through this simple and convenient method, the outer frame body 1 can be quickly installed and fixed.
