[0035] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 9 As shown:

[0037] Embodiment 1: The present invention provides an inspection drone with a photovoltaic panel cleaning function, including a drone component 1, wherein the drone component 1 includes a drone body 101 and a cleaning water tank 102, wherein the cleaning water tank 102 is fixedly mounted on the top of the drone body 101, and a cleaning water pump is provided inside the cleaning water tank 102; and further includes a cleaning component, wherein the cleaning component is composed of a flow channel mechanism 2, an adjustment mechanism 3, and an opening and closing mechanism 4;

[0038] The flow channel mechanism 2 includes a main flow channel seat 201 and two secondary flow channel seats 202. The main flow channel seat 201 is fixedly installed inside the cleaning water tank 102, and the two secondary flow channel seats 202 are symmetrically plugged into the two sides of the main flow channel seat 201; the adjustment mechanism 3 includes a driving motor 301 and a positioning rod 302. The driving motor 301 is fixedly installed on the side of the main flow channel seat 201, and the positioning rod 302 is rotatably connected to the inside of the main flow channel seat 201, and the rotating shaft of the driving motor 301 and the middle part of the rod body of the positioning rod 302 are connected through a bevel gear set; the opening and closing mechanism 4 includes a control seat 401 and a trigger seat 402. The control seat 401 is rotatably connected to the inside of the secondary flow channel seat 202, and the trigger seat 402 is plugged into the bottom of the secondary flow channel seat 202, and the bottom of the control seat 401 is plugged into the top of the trigger seat 402.

[0039] In the embodiment of the present disclosure, the outer surface of the rod body of the positioning rod 302 is provided with threads, and the positioning rod 302 is screwed inside the secondary flow channel seat 202 through the threads on the rod body. During use, the adjusting mechanism 3 can adjust the effective use length of the flow channel mechanism 2. When the driving motor 301 rotates, the rotating shaft of the driving motor 301 can drive the positioning rod 302 to rotate through bevel gears. When the positioning rod 302 rotates, it can drive the two secondary flow channel seats 202 to move synchronously and in opposite directions through the threads on the rod body, thereby changing the effective use length of the flow channel mechanism 2. When the two secondary flow channel seats 202 are at the minimum use spacing, the two secondary flow channel seats 202 will be hidden inside the main flow channel seat 201, reducing the occupied space and facilitating portability and use.

[0040] In the embodiment of the present disclosure, a normally open flow channel 2011 is provided inside the main flow channel seat 201, and the normally open flow channel 2011 is connected to a cleaning water pump inside the cleaning water tank 102 through a hose. A cleaning nozzle 5 is provided at the bottom of the normally open flow channel 2011. During use, the opening and closing mechanism 4 can automatically perform opening and closing control according to the actual use position of the secondary flow channel seat 202. Only the opening and closing mechanism 4 that exposes the main flow channel seat 201 will open to spray water for cleaning, while the opening and closing mechanism 4 that does not expose the main flow channel seat 201 will automatically be in the closed state. The normally open flow channel 2011 inside the main flow channel seat 201 is designed to be normally open, that is, when the cleaning water pump works, water can be sprayed out through the normally open flow channel 2011 and the cleaning nozzle 5 at its bottom to clean the photovoltaic panel, which is convenient for cleaning and using the photovoltaic panel.

[0041] In the embodiments of the present disclosure, a selection flow channel 2021 is provided inside the auxiliary flow channel seat 202, and the two selection flow channels 2021 are respectively connected to the cleaning water pump inside the cleaning water tank 102 through independent hoses. A radially arranged opening and closing flow channel 4011 is provided at the top of the control seat 401, and the opening and closing flow channel 4011 is arranged inside the selection flow channel 2021. During use, the opening and closing mechanism 4 that does not expose the main flow channel seat 201 will be in a closed state. At this time, the opening and closing flow channel 4011 at the top of the control seat 401 is misaligned with the selection flow channel 2021, so the water source will not enter the inside of the water distribution channel 4012 at this time, and thus the cleaning nozzle 5 at the bottom of the connection channel 4021 will not receive the water source supply. An axially arranged water distribution channel 4012 is provided at the bottom of the opening and closing flow channel 4011, and a connection channel 4021 is provided inside the trigger seat 402. The water distribution channel 4012 and the connection channel 4021 are connected, and a cleaning nozzle 5 is provided at the bottom of the connection channel 4021. After adjusting the effective use length of the flow channel mechanism 2, the opening and closing mechanism 4 exposed inside the main flow channel seat 201 will automatically open, thereby extending the effective spraying and cleaning length of the flow channel mechanism 2. When the opening and closing mechanism 4 exposes the main flow channel seat 201, the seat body of the main flow channel seat 201 loses the abutting effect on the abutting plate 4022. Thus, under the action of the opening top spring 4023, the trigger seat 402 will move downward. A helically arranged opening and closing groove 4013 is provided outside the control seat 401, and an opening and closing protrusion 4024 is provided inside the trigger seat 402. The opening and closing protrusion 4024 is inserted into the opening and closing groove 4013. When the trigger seat 402 moves downward, the opening and closing protrusion 4024 can drive the control seat 401 to rotate through the opening and closing groove 4013. After the control seat 401 rotates, the opening and closing flow channel 4011 and the selection flow channel 2021 are communicated with each other. At this time, the opening and closing flow channel 4011 can supply water to the subsequent opening and closing mechanism 4, and at the same time, the water source can sequentially enter the inside of the connection channel 4021 through the selection flow channel 2021, the opening and closing flow channel 4011, and the water distribution channel 4012 of this group of opening and closing mechanisms 4, and finally be sprayed out through the cleaning nozzle 5 at the bottom of the connection channel 4021 to realize the cleaning operation of the photovoltaic panel. This design enables changing the effective use length of the flow channel mechanism 2 to change the effective spraying length of the device, which can adapt to the cleaning operations of photovoltaic panels with different widths and is flexible to use.

[0042] In the embodiment of the present disclosure, a contact plate 4022 is provided on the side of the trigger seat 402, and the bottom of the plate body of the contact plate 4022 is inclined. An opening top spring 4023 is provided inside the contact plate 4022, and both ends of the opening top spring 4023 are respectively abutted against the inside of the contact plate 4022 and the auxiliary flow channel seat 202. When the opening and closing mechanism 4 is in a state of not protruding from the main flow channel seat 201, the contact plate 4022 is abutted by the seat body of the main flow channel seat 201, and the trigger seat 402 is hidden inside the auxiliary flow channel seat 202, and the opening and closing flow channel 4011 and the selection flow channel 2021 are misaligned with each other. During use, when the auxiliary flow channel seat 202 is hidden inside the main flow channel seat 201 again, due to the inclined side of the contact plate 4022, when the auxiliary flow channel seat 202 moves and hides, the contact plate 4022 can drive the trigger seat 402 to move upward again so that the opening and closing mechanism 4 returns to the closed state again, and the use is stable.

[0043] Specific usage method and function of this embodiment: In the present invention, the adjusting mechanism 3 can adjust the effective use length of the flow channel mechanism 2. When the driving motor 301 rotates, the rotating shaft of the driving motor 301 can drive the positioning rod 302 to rotate through bevel gears. When the positioning rod 302 rotates, it can drive two sub-flow channel seats 202 to move synchronously and in opposite directions through the rod body thread, thereby changing the effective use length of the flow channel mechanism 2. When the two sub-flow channel seats 202 are at the minimum use spacing, the two sub-flow channel seats 202 will be hidden inside the main flow channel seat 201, reducing the occupied space and also facilitating carrying and use. The opening and closing mechanism 4 can automatically perform opening and closing control according to the actual use position of the sub-flow channel seat 202. Only the opening and closing mechanism 4 exposed outside the main flow channel seat 201 will open to spray water for cleaning use, while the opening and closing mechanism 4 not exposed outside the main flow channel seat 201 will automatically be in the closed state. And the normally open flow channel 2011 inside the main flow channel seat 201 is designed to be normally open, that is, when the cleaning water pump works, the water source can be sprayed out through the normally open flow channel 2011 and the cleaning nozzles 5 at its bottom to clean the photovoltaic panel, facilitating the cleaning and washing of the photovoltaic panel. The opening and closing mechanism 4 not exposed outside the main flow channel seat 201 will be in the closed state. At this time, the opening and closing flow channel 4011 at the top of the control seat 401 and the selection flow channel 2021 are misaligned with each other, so the water source will not enter the inside of the water distribution channel 4012 at this time, and the cleaning nozzles 5 at the bottom of the connection channel 4021 will not obtain water source supply. After adjusting the effective use length of the flow channel mechanism 2, the opening and closing mechanism 4 exposed inside the main flow channel seat 201 will automatically open, thereby extending the effective spraying and cleaning length of the flow channel mechanism 2. When the opening and closing mechanism 4 is exposed outside the main flow channel seat 201, at this time, the seat body of the main flow channel seat 201 loses the resistance to the contact plate 4022. Thus, under the action of the opening spring 4023, the trigger seat 402 will move downward. When the trigger seat 402 moves downward, the opening and closing protrusion 4024 can drive the control seat 401 to rotate through the opening and closing groove 4013. When the control seat 401 rotates, the opening and closing flow channel 4011 and the selection flow channel 2021 are connected to each other. At this time, the opening and closing flow channel 4011 can provide water source supply for the subsequent opening and closing mechanism 4, and at the same time, the water source can sequentially enter the inside of the connection channel 4021 through the selection flow channel 2021, the opening and closing flow channel 4011, and the water distribution channel 4012 of this group of opening and closing mechanisms 4, and finally be sprayed out through the cleaning nozzles 5 at the bottom of the connection channel 4021 to realize the cleaning and washing operation of the photovoltaic panel. This design enables changing the effective use length of the flow channel mechanism 2 to change the effective spraying length of the device, and can adapt to the cleaning and washing operations of photovoltaic panels with different widths. When the sub-flow channel seat 202 is hidden inside the main flow channel seat 201 again, since the side of the contact plate 4022 is inclined, when the sub-flow channel seat 202 moves and hides, the contact plate 4022 can drive the trigger seat 402 to move upward again to make the opening and closing mechanism 4 return to the closed state again.
