[0002] Photovoltaic power generation is based on the photovoltaic effect, and uses solar cell modules to directly convert solar energy into electrical energy. Among the sunlight irradiated on the surface of the photovoltaic cell, except for a part that is reflected, only a part of the light entering the solar cell can cause electron transitions to generate photocurrent, and the rest is mostly dissipated in the form of heat energy. In order to improve the utilization efficiency of solar energy, it is necessary to use a photovoltaic / thermal hybrid collector device to utilize this part of heat energy.

[0048] Further, the first screw rod 51 is threadedly connected to the bracket 2 and passes through the bracket 2; the first knob 52 is fixedly arranged on one side of the first screw rod 51.

[0049] In this embodiment, the meshing block 4 has a through hole adapted to the first screw rod 51. By screwing the first screw rod 51, the first screw rod 51 can be inserted into the through hole to lock the meshing block 4. The first knob 52 is used to facilitate screwing the first screw rod 51.

[0050] Further, the second screw rod 61 is threadedly connected to the bracket 2 and passes through the bracket 2; the second knob 62 is fixedly arranged on one side of the second screw rod 61.

[0051] In this embodiment, the engaging block 4 has a through hole adapted to the second screw rod 61. By turning the second screw rod 61 and inserting the second screw rod 61 into the through hole, the engaging block 4 can be locked. The second knob 62 is used to facilitate turning the second screw rod 61.

[0052] Further, the plate body 91 is located on one side of the heat conducting shell 7; the adaptor sealing gasket 92 is fixedly arranged on one side of the plate body 91 for sealing the gap between the plate body 91 and the heat conducting shell 7 and the gaps between the plate body 91 and the plurality of partition plates 8.

[0053] In this embodiment, the plate body 91 is detachably mounted on the heat conducting shell 7 by a plurality of the screws 10. The adaptor sealing gasket 92 is used for sealing the gap between the plate body 91 and the heat conducting shell 7 and the gaps between the plate body 91 and the plurality of partition plates 8 to prevent water leakage.

[0054] Further, a plurality of electric telescopic rods 1301 are respectively fixedly arranged on the mounting frame 3; the guiding frame 1302 is fixedly arranged at the output ends of the plurality of electric telescopic rods 1301; the guide rail 1303 is slidably arranged on the guiding frame 1302; the lead screw 1304 is rotatably connected to the guiding frame 1302, threadedly connected to the guide rail 1303 and passes through the guide rail 1303; the first motor 1305 is fixedly arranged on one side of the guiding frame 1302; the output end of the first motor 1305 is fixedly connected to the lead screw 1304; the mounting box 1306 is slidably arranged on the guide rail 1303; the mounting shaft 1307 is rotatably arranged on the mounting box 1306; the second motor 1308 is fixedly arranged on one side of the mounting box 1306; the output end of the second motor 1308 is fixedly connected to the mounting shaft 1307; the rack 1310 is fixedly arranged on the guide rail 1303 and passes through the mounting box 1306; the gear 1309 is fixedly arranged on the mounting shaft 1307 and meshes with the rack 1310.

[0055] In this embodiment, a plurality of the electric telescopic rods 1301 can drive the guide frame 1302 to approach or move away from the water flow channel 15, and finally drive the cleaning brush mechanism 14 to approach or move away from the water flow channel 15. When approaching, it can extend into the water flow channel 15; the guide frame 1302 is used for slidably mounting the guide rail 1303. When the first motor 1305 drives the lead screw 1304 to rotate, the guide rail 1303 can be driven to slide along the guide frame 1302, and finally drive the cleaning brush mechanism 14 to move along the direction of the guide frame 1302; the guide rail 1303 is used for slidably mounting the mounting box 1306. When the second motor 1308 drives the mounting shaft 1307 to rotate, the mounting shaft 1307 drives the gear 1309 to rotate. The gear 1309 meshes with the rack 1310. While the gear 1309 rotates along the rack 1310, it also moves in the length direction of the rack 1310. The length direction of the rack 1310 is the same as the length direction of the guide rail 1303. Therefore, the mounting box 1306 slides along the guide rail 1303, and finally drives the cleaning brush mechanism 14 to move along the direction of the guide rail 1303; in this way, the cleaning brush mechanism 14 can extend into the water flow channel 15 and move out along the same route as the water flow channel 15, and can move along the water flow channel 15 for cleaning.

[0058] Further, the rotating shaft 141 is rotatably arranged on the mounting box 1306 and passes through the mounting box 1306; the cylindrical brush 142 is fixedly arranged on the rotating shaft 141; the driving bevel gear 143 is fixedly arranged on the mounting shaft 1307; the driven bevel gear 144 is fixedly arranged on the rotating shaft 141 and meshes with the driving bevel gear 143.

[0059] In this embodiment, the end and the side of the cylindrical brush 142 away from the rotating shaft 141 are both provided with bristles. When the mounting shaft 1307 rotates, it will drive the driving bevel gear 143 to rotate. The driving bevel gear 143 drives the driven bevel gear 144 to rotate, and the driven bevel gear 144 drives the rotating shaft 141 to rotate, and finally drives the cylindrical brush 142 to rotate. While rotating, the cylindrical brush 142 moves along the flowing water channel 15 for cleaning.

[0060] In a solar thermal and photovoltaic hybrid heat collection device according to this embodiment, during normal use, the two first locking mechanisms 5 lock the two engaging blocks 4, the mounting frame 3 remains in an inclined state, and the photovoltaic panel 1 also remains in an inclined state to better receive sunlight for power generation. Water enters from the water inlet pipe 11, and when passing through the flowing water channel 15, it exchanges heat with the photovoltaic panel 1 through the heat conducting shell 7 and becomes hot water flowing out from the water outlet pipe 12. This can not only lower the temperature of the photovoltaic panel 1, but also take away and utilize the heat energy absorbed by the photovoltaic panel 1. When cleaning is required, the two first locking mechanisms 5 release the two engaging blocks 4, rotate the mounting frame 3 to drive the photovoltaic panel 1 to a vertical state, and lock the two engaging blocks 4 with the two second locking mechanisms 6. Diluted pickling solution is introduced from the water outlet pipe 12 to clean the scale in the flowing water channel 15. Then, a plurality of screws 10 are unscrewed, the sealing plate 9 is removed, the sealing plate 9 is cleaned, and the moving mechanism 13 is started to drive the cleaning brush mechanism 14 to extend into the flowing water channel 15 and move along the flowing water channel 15 for cleaning, thereby solving the problem that the existing solar thermal and photovoltaic hybrid heat collection device is inconvenient to clean.
