[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 disclosed embodiment, the outside of the rod body of the positioning rod 302 is provided with a thread, and the positioning rod 302 is screwed to the inside of the secondary flow channel seat 202 through the rod body thread. During use, the adjustment mechanism 3 can adjust the effective use length of the flow channel mechanism 2. When the drive motor 301 is rotating, the rotating shaft of the drive motor 301 can drive the positioning rod 302 to rotate through the bevel gear. 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 rod body thread, thereby changing the effective use length of the flow channel mechanism 2. When the two secondary flow channel seats 202 are at the minimum usage spacing, the two secondary flow channel seats 202 will be hidden inside the main flow channel seat 201, reducing the occupied space and also making it convenient to carry and use.

[0040] In the disclosed embodiment, 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 the cleaning water pump inside the cleaning water tank 102 through a hose, and 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 is exposed to the main flow channel seat 201 will start to spray water for cleaning, while the opening and closing mechanism 4 that is not exposed to the main flow channel seat 201 will automatically be in a closed state, and the normally open flow channel 201 inside the main flow channel seat 201 is a normally open design, that is, when the cleaning water pump is working, water can be sprayed 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 washing the photovoltaic panel.

[0041] In the embodiment of the present disclosure, a selection flow channel 2021 is provided inside the secondary 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.

At this time, the opening and closing flow channel 4011 on the top of the control seat 401 and the selection flow channel 2021 are mutually misaligned, so that the water source will not enter the water diversion channel at this time. The inside of the opening and closing flow channel 4012, so that the cleaning nozzle 5 at the bottom of the connecting channel 4021 will not obtain water supply, the bottom of the opening and closing flow channel 4011 is provided with an axially arranged water diversion channel 4012, and the inside of the trigger seat 402 is provided with a connecting channel 4021, the water diversion channel 4012 and the connecting channel 4021 are connected, and the bottom of the connecting channel 4021 is provided with a cleaning nozzle 5, when the effective use length of the flow channel mechanism 2 is adjusted, the opening and closing mechanism 4 exposed inside the main flow channel seat 201 will automatically open, thereby extending the effective jet cleaning length of the flow channel mechanism 2, when the opening and closing mechanism 4 is exposed from the main flow channel seat 201, at this time, the seat body of the main flow channel seat 201 loses its resistance to the resistance plate 4022, so that under the action of the opening top spring 4023, the trigger seat 402 will move downward, the control seat 401 is provided with a spiral opening and closing groove 4013 on the outside, and the trigger seat 402 is provided with an opening and closing protrusion 4024 on the inside, and the opening and closing protrusion 4024 is plugged 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. When the control seat 401 rotates, the opening and closing flow channel 4011 and the selection flow channel 2021 are interconnected. At this time, the opening and closing flow channel 4011 can provide water supply for the subsequent opening and closing mechanism 4. At the same time, the water source can also enter the interior of the connecting channel 4021 through the selection flow channel 2021, the opening and closing flow channel 4011, and the water diversion channel 4012 of the opening and closing mechanism 4 in turn, and finally be sprayed out through the cleaning nozzle 5 at the bottom of the connecting channel 4021 to realize the cleaning operation of the photovoltaic panel. This design makes it possible to change 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 operation of photovoltaic panels of different widths and is flexible to use.

In use, when the secondary 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 secondary flow channel seat 202 moves and hides, the contact plate 4022 can drive the trigger seat 402 to move up again so that the opening and closing mechanism 4 is restored to the closed state, and it is stable to use.

[0043] Specific usage and function of this embodiment: In the present invention, the adjustment mechanism 3 can adjust the effective use length of the flow channel mechanism 2. When the drive motor 301 is rotating, the shaft of the drive motor 301 can drive the positioning rod 302 to rotate through the bevel gear. 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 rod body thread, 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 making it convenient to carry and 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, and only the main flow channel seat 202 is exposed. 01 will open the opening and closing mechanism 4 to spray water for cleaning, while the opening and closing mechanism 4 that is not exposed to the main channel seat 201 will automatically be in a closed state, and the normally open flow channel 2011 inside the main channel seat 201 is a normally open design, that is, when the cleaning water pump is working, the water source can be sprayed through the normally open flow channel 2011 and the cleaning nozzle 5 at the bottom thereof to clean the photovoltaic panel, which is convenient for cleaning and washing the photovoltaic panel, and the opening and closing mechanism 4 that is not exposed to the main 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 and the selection flow channel 2021 are misaligned with each other, so that the water source will not enter the interior of the water diversion channel 4012 at this time, so that the cleaning nozzle 5 at the bottom of the connecting channel 4021 will not obtain the water source 4022, the opening and closing mechanism 4023 is used to open the main flow channel seat 201, and the opening and closing mechanism 4024 is used to open the main flow channel seat 201, and the opening and closing mechanism 4021 is used to open the main flow channel seat 201. It is also possible to enter the interior of the connecting channel 4021 through the selection channel 2021, the opening and closing channel 4011, and the water diversion channel 4012 of the opening and closing mechanism 4 in sequence, and finally be sprayed out through the cleaning nozzle 5 at the bottom of the connecting channel 4021 to achieve the cleaning operation of the photovoltaic panel. This design makes it possible to change the effective spraying length of the device by changing the effective use length of the flow channel mechanism 2, and can adapt to the cleaning operation of photovoltaic panels of different widths. When the secondary flow channel seat 202 is hidden inside the main flow channel seat 201 again, since the side of the resistance plate 4022 is designed to be inclined, when the secondary flow channel seat 202 is moved and hidden, the resistance plate 4022 can drive the trigger seat 402 to move upward again, so that the opening and closing mechanism 4 is restored to the closed state.
