Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] Please refer to Figures 1 to 8 The solar flat plate collector with high-temperature heat dissipation protection function in the embodiment comprises a solar flat plate collector main body 1, the solar flat plate collector main body 1 comprises a solar flat plate collector body 11 and a cooling frame 12, the outside of the cooling frame 12 is fixedly connected with two L-shaped frames 2, the top of the solar flat plate collector body 11 is provided with a cleaning mechanism 3, the lower surface of the cleaning mechanism 3 is provided with an abutting structure 4 for self-adapting abutment, and the outside of the L-shaped frame 2 is provided with an air blowing structure 5 and a transmission mechanism 6 which are linked with the cleaning mechanism 3 and the abutting structure 4 respectively.

[0025] Among them, the solar flat plate collector body 11 is fixedly connected to the inside of the cooling frame 12, and the bottom of the cooling frame 12 is fixedly connected with four supporting legs.

[0026] In the embodiment, the cleaning mechanism 3 comprises a moving block 31 arranged between the two L-shaped frames 2, the bottom of the moving block 31 is hingedly connected with a connecting seat 32, one side of the connecting seat 32 is fixedly connected with a moving plate 33, a double-shaft air cylinder 34 is hingedly connected between the moving block 31 and the moving plate 33, and the lower surface of the moving plate 33 is provided with a cleaning brush 35.

[0027] The top of the cleaning brush 35 is fixedly connected with a limiting rod 36 extending to the upper surface of the moving plate 33, and the outer surface of the top end of the limiting rod 36 is fixedly connected with a limiting sleeve. There are four groups of limiting rods 36, and the top of the cleaning brush 35 abuts against the top of the solar flat plate collector body 11. Under different working conditions, the solar flat plate collector body 11 may have different shapes of stains or dust accumulation. The biaxial air cylinder 34 can adjust the contact angle of the cleaning brush 35 according to the actual situation, so that the cleaning brush 35 better fits the surface of the solar flat plate collector body 11, enhances the cleaning strength, and improves the cleaning quality. At the same time, the biaxial air cylinder 34 also has a certain buffering effect, which can reduce the impact force when the cleaning brush 35 contacts the surface of the solar flat plate collector body 11, and avoid damaging the surface of the solar flat plate collector body 11.

[0028] In the embodiment, the abutting structure 4 includes a plug cylinder 41 fixedly connected to the top of the left L-shaped frame 2 and a mounting cylinder 42 fixedly connected to the top of the cleaning brush 35. The inside of the mounting cylinder 42 is slidably connected with a displacement plate 47, the top of the displacement plate 47 is fixedly connected with a connecting shaft 48 extending to the top of the mounting cylinder 42, the top end of the connecting shaft 48 is fixedly connected with a fixed sheet 49, the fixed sheet 49 is fixedly connected to the bottom of the moving plate 33, and the plug cylinder 41 and the mounting cylinder 42 are fixedly connected with a communication pipe 43. When the moving block 31 drives the connecting seat 32 to move, the connecting seat 32 abuts against one end of the piston rod 44, pushes the piston rod 44 to displace and pressurizes the inside of the plug cylinder 41. The pressure change in the plug cylinder 41 is transmitted to the mounting cylinder 42 through the communication pipe 43, so that the displacement plate 47 and other structures in the mounting cylinder 42 move downward, and in turn drive the cleaning brush 35 to better adapt to abut against the top of the solar flat plate collector body 11, so as to realize automatic adjustment of the contact pressure of the cleaning brush 35 and the surface of the solar flat plate collector body 11, adapt to the cleaning requirements under different working conditions, and ensure the cleaning effect.

[0029] The inside of the plug cylinder 41 is slidably connected with a piston rod 44 extending to the outside thereof, the piston rod 44 is located on one side of the connecting seat 32, the outside of the piston rod 44 is fixedly connected with a connecting ring 45, the connecting ring 45 and the plug cylinder 41 are fixedly connected with a return spring 46, and the return spring 46 is connected around the outside of the piston rod 44.

When the moving block 31 moves reversely, the elastic force of the return spring 46 can quickly reset the piston rod 44, so as to ensure the stability of the reciprocating motion of the abutting structure 4, so that the cleaning brush 35 can continuously and stably adapt to abut against the surface of the solar flat plate collector body 11.

[0030] In this embodiment, the transmission mechanism 6 includes a driving motor 61 fixedly installed on the outside of the left L-shaped frame 2 and a rotating shaft 63 rotatably connected to the inside of the left L-shaped frame 2 and extending to the outside thereof, a transmission gear 62 fixedly connected to the output shaft of the driving motor 61, a rotating disc 64 fixedly connected to the outside of the rotating shaft 63, a toothed disc 65 fixedly installed on the outside of the rotating shaft 63 and engaged with the transmission gear 62, and an adjusting structure 66 provided on the outside of the toothed disc 65.

[0031] The adjusting structure 66 includes a mounting seat 661 fixedly connected to the outside of the rotating disc 64, an adjusting screw 662 rotatably connected to the inside of the mounting seat 661 and extending to the lower surface thereof, a knob 663 fixedly connected to the top end of the adjusting screw 662, a threaded block 664 threadedly connected to the outside of the adjusting screw 662, a crank 665 rotatably connected to the outside of the threaded block 664, and the middle part of the moving block 31.

[0032] The rotating knob 663 drives the adjusting screw 662 to rotate, the threaded block 664 moves up and down on the outside of the adjusting screw 662, and the reciprocating stroke and motion law of the moving block 31 are changed through the crank 665, so that the motion range and intensity of the cleaning brush 35 can be flexibly adjusted according to the actual working condition and cleaning requirement of the solar flat plate collector body 11, and the adaptability and controllability of the equipment are improved.

[0033] Specifically, two guide rods 67 are fixedly connected between the two L-shaped frames 2, two buffer springs 68 are fixedly connected to the outside of the right L-shaped frame 2, and the two buffer springs 68 are sequentially connected to the outside of the two guide rods 67. The guide rods 67 provide accurate guidance for the reciprocating sliding of the moving block 31, ensuring the linearity and accuracy of the movement of the moving block 31. The buffer springs 68 can buffer and absorb the impact when the moving block 31 moves to the extreme position, reduce the impact force between the moving block 31 and the L-shaped frame 2, prolong the service life of the equipment, make the movement of the moving block 31 more stable, and improve the reliability and stability of the entire transmission mechanism 6.

[0034] It should be noted that the moving block 31 is slidably connected to the outside of the two guide rods 67 and abuts against the end of the buffer spring 68 away from the right L-shaped frame 2, the connecting seat 32 is reciprocatingly slidably connected to the outside of the two L-shaped frames 2 through the moving block 31 and abuts against the end of the piston rod 44 away from the plug barrel 41.

[0035] In this embodiment, the blowing structure 5 includes a spray pipe 51 fixedly connected to the top of the cooling frame 12 and a piston cylinder 52 fixedly connected to the top of the right L-shaped frame 2. The inside of the piston cylinder 52 is further connected with a piston block 53. The outside of the piston block 53 is fixedly connected with a plug rod 54 extending into the inside of the piston cylinder 52. The end of the plug rod 54 away from the piston block 53 is fixedly connected with a transmission plate 55 which is slidingly connected to the outside of the top guide rod 67 and fixedly connected with the top buffer spring 68. When the moving block 31 reciprocally slides, the plug rod 54 and the piston block 53 are driven by the transmission plate 55 to reciprocally move in the piston cylinder 52, so that the gas in the piston cylinder 52 is delivered to the spray pipe 51 through the gas delivery pipe 57 and sprayed out.

[0036] The outside of the spray pipe 51 is fixedly connected with a plurality of nozzles in communication with the top surface of the solar flat plate collector body 11. The gas delivery pipe 57 is fixedly connected between the piston cylinder 52 and the spray pipe 51. The top of the piston cylinder 52 is fixedly connected with the gas inlet pipe 56. The inside of each of the gas inlet pipe 56 and the gas delivery pipe 57 is elastically hinged with a check valve. The plurality of nozzles can uniformly spray the gas to the top of the solar flat plate collector body 11, increase the contact area of the gas with the surface of the solar flat plate collector body 11, and improve the heat dissipation efficiency. Meanwhile, the uniform airflow distribution can better remove the dust and stains on the surface of the solar flat plate collector body 11, and cooperates with the cleaning mechanism 3.

[0037] The working principle of the above embodiment is as follows: When heat dissipation and cleaning are needed, the driving motor 61 is started, and the output shaft drives the transmission gear 62 to rotate. The transmission gear 62 is engaged with the toothed disc 65, thereby driving the rotating shaft 63 and the rotating disc 64 to rotate. The rotating knob 663 drives the adjusting screw 662 to rotate, so that the threaded block 664 moves up and down outside the adjusting screw 662. The reciprocating stroke and movement law of the moving block 31 are changed by the crank 665. The moving block 31 reciprocally slides on the two guide rods 67. The guide rods 67 ensure the linearity and accuracy of the movement of the moving block 31. The buffer spring 68 plays a buffering and damping role when the moving block 31 moves to the two end limit positions, thereby reducing the impact force. The moving block 31 drives the connecting seat 32 to reciprocally move. The connecting seat 32 is reciprocally slidingly connected to the outside of the two L-shaped frames 2 by the moving block 31. When the moving block 31 reciprocally moves, the double-shaft air cylinder 34 can adjust the contact angle of the cleaning brush 35 according to the actual situation, so that the cleaning brush 35 better fits the surface of the solar flat plate collector body 11, enhances the cleaning strength, improves the cleaning quality, reduces the impact force, and avoids damaging the surface of the solar flat plate collector body 11. The connecting seat 32 moves and abuts against one end of the piston rod 44, pushes the piston rod 44 to displace in the plug cylinder 41, increases the pressure in the plug cylinder 41, the pressure change is transmitted to the mounting cylinder 42 through the communication pipe 43, and the displacement plate 47 and other structures in the mounting cylinder 42 move downward, drive the cleaning brush 35 to better adapt to abutting against the top of the solar flat plate collector body 11, realize the automatic adjustment of the contact pressure between the cleaning brush 35 and the surface of the solar flat plate collector body 11, and adapt to the cleaning requirement under different working conditions; When the moving block 31 moves and pushes the piston rod 44 to move in the plug cylinder 41, the reset spring 46 is compressed to generate an elastic force, and when the moving block 31 moves reversely, the elastic force of the reset spring 46 makes the piston rod 44 reset quickly, guarantees the stability of the reciprocating movement of the abutting structure 4, and makes the cleaning brush 35 continuously and stably adapt to abutting against the surface of the solar flat plate collector body 11; When the moving block 31 reciprocally slides, the plug rod 54 and the piston block 53 are driven by the transmission plate 55 to reciprocally move in the piston cylinder 52, the gas in the piston cylinder 52 is transported to the spray pipe 51 through the gas conveying pipe 57 and sprayed from multiple nozzles, the multiple nozzles uniformly spray the gas to the top of the solar flat plate collector body 11, increase the contact area between the gas and the surface of the solar flat plate collector body 11, improve the heat dissipation efficiency, and the uniform airflow distribution better removes the dust and stains on the surface of the solar flat plate collector body 11, which cooperates with the cleaning mechanism 3.
