[0038] Please refer to the attached document. Figures 1-5 This application provides a water spraying component 100, which is applied to a photovoltaic cleaning robot and is used to spray water onto the roller brush 32 or the surface of the photovoltaic module.

[0039] Please refer to the attached document. Figures 1-5In this embodiment, the water spray assembly 100 includes a robot body 10, a water inlet module 20, and a roller brush module 30. The robot body 10 is provided with a support base 11. The water inlet module 20 includes a connecting seat 21 and a water inlet pipe 22. The connecting seat 21 is detachably connected to the support base 11 and can be quickly connected or disconnected from the support base 11. The water inlet pipe 22 is connected to the connecting seat 21. The roller brush module 30 includes a bracket 31, a roller brush 32, and at least one water spray element 33. The bracket 31 is connected to the robot body 10. The roller brush 32 is rotatably connected to... The bracket 31 is used to clean the photovoltaic module; the water spray component 33 is located on one side of the roller brush 32 and is connected to the water inlet pipe 22 through the water pipe; the water spray component 33 is used to spray water onto the roller brush 32 or the surface of the photovoltaic module to achieve quick disassembly of the connecting seat 21, thereby facilitating the quick disassembly of the water inlet module 20 relative to the robot body 10 through the cooperation of the connecting seat 21 and the support seat 11, avoiding the water inlet module 20 being connected to the robot body 10 by welding and thus unable to be quickly disassembled, improving the ease of installation and removal of the water inlet module 20 of the water spray component 100.

[0040] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the robot body 10 serves as a supporting component of the water spray assembly 100. The robot body 10 is used to support the water inlet module 20 and the roller brush module 30. The robot body 10 is provided with a support base 11.

[0041] The water inlet module 20 includes a connecting seat 21 and a water inlet pipe 22. The connecting seat 21 is located on the upper side of the support seat 11 and is detachably connected to the support seat 11. The connecting seat 21 can be quickly connected or disconnected from the support seat 11. The water inlet pipe 22 is connected to the connecting seat 21 to enable quick disconnection of the connecting seat 21. This facilitates the quick disconnection of the water inlet module 20 relative to the robot body 10 through the cooperation of the connecting seat 21 and the support seat 11. This avoids the water inlet module 20 being connected to the robot body 10 by welding, which would prevent quick disconnection and improves the ease of installation and removal of the water inlet module 20 of the water spray assembly 100.

[0042] The roller brush module 30 includes a bracket 31, a roller brush 32, and at least one water spraying component 33. The bracket 31 is located on the front side of the robot body 10 and is connected to the robot body 10 so that the roller brush module 30 can be connected to the robot body 10 through the bracket 31. The roller brush 32 is rotatably connected to the bracket 31 so as to adjust the position of the roller brush 32 relative to the bracket 31. The roller brush 32 is used to clean the photovoltaic module and ensure the cleanliness of the photovoltaic module. The water spraying component 33 is located outside the roller brush 32 and is connected to the water inlet pipe 22 through a water pipe. The water spraying component 33 is used to spray water onto the roller brush 32 or the surface of the photovoltaic module so that the water output from the water inlet pipe 22 can flow to the water spraying component 33 through the water pipe, thereby facilitating the water spraying component 33 to rinse the roller brush 32 or the photovoltaic module.

[0043] Please refer to the attached document. Figures 1-4 In this embodiment, the support base 11 is provided with a first quick-release part 111, and the connecting base 21 is provided with a first quick-release hole 211. When the connecting base 21 is connected to the support base 11 in a quick-release manner, the first quick-release hole 211 allows the first quick-release part 111 to pass through, and the end 111b of the first quick-release part 111 can contact the surface of the connecting base 21 to limit the disconnection of the connecting base 21. This allows the connecting base 21 to cooperate with the first quick-release part 111 through the first quick-release hole 211 to achieve quick disconnection with the support base 11, thereby facilitating the quick disconnection of the water inlet module 20. This avoids the water inlet module 20 being connected to the robot body 10 by welding and thus unable to be quickly disconnected, improving the ease of installation and removal of the water inlet module 20 of the water spray assembly 100.

[0044] Please refer to the attached document. Figures 1-4 In this embodiment, the first quick-release hole 211 includes a first through hole 2111 and a first elongated hole 2112; the first elongated hole 2112 communicates with the first through hole 2111 and extends along the length direction of the connecting seat 21; the end portion 111b of the first quick-release part 111 passes through the first through hole 2111, and the connecting seat 21 moves along the length direction of the support seat 11, so that the main body portion 111a of the first quick-release part 111 passes through the first elongated hole 2112. At the same time, the end portion 111b of the first quick-release part 111 restricts the disengagement of the connecting seat 21, so that the first quick-release part 111 can enter the first elongated hole 2112 through the first through hole 2111, thereby facilitating the inner sidewall of the first elongated hole 2112 to restrict the position of the first quick-release part 111, so as to realize the installation of the connecting seat 21 relative to the support seat 11. When the first quick-release part 111 moves from the first elongated hole 2112 to the first through hole 2111, the connecting seat 21 is lifted upward to disengage from the first quick-release part 111, so as to realize the quick release of the connecting seat 21 relative to the support seat 11.

[0045] Please refer to the attached document. Figures 1-4 In this embodiment, the inner wall of the first through hole 2111 and the inner wall of the first elongated hole 2112 are connected by an arc transition. An arc guide surface 2113 is formed between the inner wall of the first through hole 2111 and the inner wall of the first elongated hole 2112. The arc guide surface 2113 is used to guide the main body 111a of the first quick-release part 111 into the first elongated hole 2112, so that the main body 111a of the first quick-release part 111 can enter the first elongated hole 2112 through the first through hole 2111 under the guidance of the arc guide surface 2113. This ensures the smoothness of the assembly and disassembly process of the connecting seat 21 relative to the support seat 11, avoids jamming or damage caused by impact between the first quick-release part 111 and the inner wall of the first elongated hole 2112, and improves the convenience and efficiency of operation.

[0046] Please refer to the attached document. Figures 1-4In this embodiment, the end 111b of the first quick-release part 111 and the first through hole 2111 are both arranged in a circular shape so that the outer contour of the first quick-release part 111 matches the inner contour of the first through hole 2111. The diameter of the end 111b of the first quick-release part 111 is smaller than the diameter of the first through hole 2111 so that the first quick-release part 111 can be directly inserted into the first through hole 2111, improving the convenience of the end 111b of the first quick-release part 111 entering the first through hole 2111. The diameter of the end 111b of the first quick-release part 111 is larger than the width of the first elongated hole 2112 so that the first elongated hole 2112 restricts the range of motion of the end 111b of the first quick-release part 111, ensuring the position of the connecting seat 21 relative to the support seat 11.

[0047] Please refer to the attached document. Figures 1-5 In this embodiment, the support base 11 is further provided with a positioning hole 11a, which is located on one side of the first quick-release part 111; the connecting base 21 is provided with a positioning post 212, which is elastically movable relative to the connecting base 21 so that the positioning post 212 can move up and down in the vertical direction. The positioning post 212 can be inserted into the positioning hole 11a, so that the positioning post 212 and the positioning hole 11a are positioned and connected, so that the inner sidewall of the positioning hole 11a restricts the position of the positioning post 212, thereby facilitating the connecting base 21 to achieve a positioning connection with the support base 11 through the cooperation of the positioning post 212 and the positioning hole 11a, ensuring the positional accuracy of the connecting base 21 relative to the support base 11, and avoiding positional deviation of the connecting base 21 relative to the support base 11.

[0048] Please refer to the attached document. Figures 1-5 In this embodiment, the connecting seat 21 has a protrusion 213, which protrudes outward from the peripheral sidewall of the connecting seat 21. The positioning pin 212 is movably connected to the protrusion 213 and moves in the vertical direction to adjust the height of the positioning pin 212 relative to the protrusion 213, thereby facilitating the vertical movement of the positioning pin 212 relative to the connecting seat 21 through the protrusion 213. The protrusion 213 has a through hole extending along the length of the protrusion 213. The positioning pin 212 passes through the through hole and moves in the vertical direction relative to the through hole. The protrusion 213 has an elastic element 2131 inside. The two ends of the elastic element 2131 are connected to the protrusion 213 and the positioning pin 212, respectively, and apply an elastic force to the positioning pin 212, so that the positioning pin 212 is inserted into the positioning hole 11a under the elastic force, so that the positioning pin 212 can move elastically relative to the protrusion 213 through the elastic element 2131. Optionally, the elastic element 2131 is a spring.

[0049] Please refer to the attached document. Figures 1-4In this embodiment, the water inlet module 20 further includes a rotating seat 23, which is disposed on the upper side of the connecting seat 21. The rotating seat 23 is rotatably connected to the connecting seat 21 to facilitate adjustment of the position of the rotating seat 23 relative to the connecting seat 21. The water inlet pipe 22 is connected to the rotating seat 23 so that the water inlet pipe 22 rotates with the rotation of the rotating seat 23, thus preventing the water inlet pipe 22 from getting tangled in the connecting seat 21. A bearing 24 is provided between the rotating seat 23 and the connecting seat 21. The bearing 24 is installed in the connecting seat 21, and the rotating seat 23 is sleeved in the bearing 24 so that the rotating seat 23 can rotate relative to the connecting seat 21 through the bearing 24, thus ensuring the rotation effect of the rotating seat 23.

[0050] Please refer to the attached document. Figures 1-2 In this embodiment, the support 31 is swayably connected to the robot body 10 and swings vertically relative to the robot body 10 to adjust its vertical position. The roller brush 32 swings with the support 31, allowing it to swing vertically when encountering uneven photovoltaic modules, thus facilitating the advancement of the roller brush module 30. The support 31 is connected to an outer cover 311, and a water sprayer 33 is connected to the outer cover 311, receiving water output from the water inlet pipe 22 via a water pipe. The outer cover 311 prevents water sprayed by the water sprayer 33 from splashing into the external environment. The water sprayer 33 is arranged at an angle to spray water towards the roller brush 32 or the surface of the photovoltaic module.
