DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments 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.

[0041] Please refer to the attached Figure 1-Figure 5 The present invention provides a technical solution: an intelligent tethered drone for photovoltaic panel cleaning and inspection, comprising:

[0042] Unmanned vehicle 1;

[0043] The camera 3 is installed at the front end of the drone body 1 and transmits the image to the ground terminal in real time;

[0044] The jet cleaning mechanism 2 is installed on the belly of the drone body 1. The jet cleaning mechanism 2 is composed of a main body 24, a swing driving mechanism, a pipe clamping assembly 33, and a nozzle 21 installed at the front end of the main body 24. The rear end of the main body 24 is connected with a push cylinder 25. The water injection nozzle 27 of the main body 24 is connected to the ground water supply equipment through a water pipe. The pipe clamping assembly 33 is installed in the water injection nozzle 27. The pipe clamping assembly 33 can intermittently squeeze the water pipe inserted therein, so that the water flow is sprayed in a point-interrupted manner.

[0045] The main body 24 is connected to the drone body 1 via a swing-driving mechanism, and the swing-driving mechanism can drive the main body 24 to swing up and down.

[0046] In this embodiment, the tube clamping assembly 33 includes:

[0047] Two ring bodies 331 are provided and are symmetrically arranged, and each ring body 331 is provided with a protrusion;

[0048] An orienting plate 332 connected between the raised portions of the two ring bodies 331;

[0049] Three connecting plates 333 are provided and arranged in a circumferential array between the two ring bodies 331;

[0050] and pushing components, the number of which is the same as that of the connecting plates 333, each connecting plate 333 is equipped with a pushing component, each pushing component is driven by the moving end of the second pushing cylinder 341 to perform a pushing action, and the fixed end of the second pushing cylinder 341 is fixedly mounted on the fixed seat 340 of the connecting plate 333;

[0051] Specifically, the three push cylinders 341 perform telescopic actions synchronously to drive the three pushing components to perform cooperative squeezing actions on the water pipe, so that the squeezing part of the water pipe can generate a higher local pressure, thereby more effectively penetrating or cleaning the target surface.

[0052] In this embodiment, the pushing assembly includes:

[0053] The slide seat 338 is matched and slidably connected with the second slideway 339 of the connecting plate 333, and the slide seat 338 is driven by the second push cylinder 341;

[0054] The base 335 has two rotating handles 336 on both sides thereof, and both ends of each rotating handle 336 are rotatably connected to the base 335 and the connecting plate 333 respectively;

[0055] There are two push rods 337 , each of which is rotatably connected to the slide seat 338 and the base 335 ; and a pressing block 334 fixed on the base 335 .

[0056] Specifically, when the push cylinder 341 pushes the slide 338 forward, the slide 338 pushes the base 335 through the push rod 337, and the base 335 gradually moves inward under the limit of the rotating handle 336, so that the pressure block 334 presses the extrusion part of the water pipe, making its flow cavity smaller and accumulating pressure. When the push cylinder 341 pulls the slide 338 backward, the pressure block 334 moves to its original position in the same way as above, so that the water pipe is not squeezed, the flow cavity surface at its extrusion part is enlarged, and the pressure is released, which is repeated to form a point-interrupted pressurized jet.

[0057] In this embodiment, the two rotating handles 336 located on the same side are always arranged in parallel.

[0058] In this embodiment, one end of the pressing block 334 is convex, which reduces the pressing area of ​​the pressing block 334 on the water pipe, thereby reducing the pushing force required during the squeezing.

[0059] In this embodiment, the push rod 337 includes:

[0060] A rod 3371, one end of which is rotatably mounted on a slide 338;

[0061] The second rod 3374, one end of which is away from the first rod 3371, is rotatably mounted on the base 335, the other end of the second rod 3374 is provided with a sliding hole, and the side wall of the second rod 3374 is provided with a slideway 3373 connected to the sliding hole;

[0062] The inner rod 3376 has one end connected to the end of the rod 1 3371 away from the slide seat 338, and the other end of the inner rod 3376 slides into the slide hole and is connected to the slide post 3375, and the slide post 3375 slides with the slideway 3 3373;

[0063] and a spring 2 3372 connected between the rod 1 3371 and the rod 2 3374 and wound around the side wall of the inner rod 3376;

[0064] It should be noted that the spring 2 3372 has a certain spring stress to exert an appropriate squeezing effect on the water pipe to avoid excessive squeezing causing excessive pressure in the water pipe and resulting in the water pipe rupture.

[0065] In this embodiment, the swing driving mechanism includes:

[0066] Two fixed handles 23 are provided and symmetrically arranged on both sides of the main body 24. A rotating shaft 22 is connected between the two fixed handles 23, and the rotating shaft 22 can be rotatably inserted into the through hole of the main body 24;

[0067] The pin heads 32 are the same in number as the fixed handles 23 and are respectively connected to the bottoms of the two fixed handles 23, and each pin head 32 is matched and slidably arranged in an arc-shaped slideway 26 of the main body 24;

[0068] A push rod 31, which is disposed in the main body 24 and drivingly connected to the driving end of the push cylinder 25;

[0069] The column head 28 is fixed to the left end of the push rod 31, and the column head 28 is fixedly connected to the rotating shaft 22 by a telescopic rod 29;

[0070] and a spring 1 30 connected between the column head 28 and the rectangular opening wall of the main body 24, the spring 1 30 being wound around the side wall of the push rod 31;

[0071] Specifically, the push cylinder 25 drives the push rod 31 to push and pull, and drives the telescopic rod 29 to flip relative to the rotating shaft 22 through the column head 28, so that the fixed handle 23 is flipped relative to the main body 24, and under the constraints of the slide 26 and the pin head 32, the main body 24 is driven to swing back and forth up and down, thereby increasing the spray range of the spray water flow.

[0072] In this embodiment, the arc-shaped slideway 26 is arranged cocentrically with the rotating shaft 22 , so that the pin head 32 can rotate around the rotating shaft 22 as the center while sliding in the slideway 26 .

[0073] In this embodiment, the telescopic frequency of the second push cylinder 341 is at least three times the telescopic frequency of the first push cylinder 25;

[0074] That is to say, when the push cylinder 1 25 drives the main body 24 to perform an up and down swinging action, the push cylinder 2 341 can perform at least three intermittent spraying actions, thereby increasing the cleaning efficiency of the jet cleaning mechanism.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
