Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a cleaning UAV and a cleaning device. Background Technology

[0002] With the continuous improvement of people's living standards and the enhancement of environmental awareness, there are more and more photovoltaic power stations and buildings with glass curtain walls. Since the photovoltaic panels of photovoltaic power stations and the glass curtain walls of buildings are exposed to the outdoors for a long time, they need to be cleaned regularly. At present, the most common cleaning method is manual cleaning. However, manual cleaning has safety hazards, and there are many blind spots that cannot be reached by manual cleaning, so it cannot achieve a good cleaning effect.

[0003] To address the aforementioned issues, the invention patent with publication number CN113953241A proposes a flying device and cleaning method for high-pressure rinsing of photovoltaic panels. This flying device and cleaning method, after completing charging and water refilling at a docking station, fly at a predetermined altitude and route. It uses an image acquisition device to acquire and analyze images of the photovoltaic panels. If stains are detected, the control system controls the rotor to fly above the stain location. The nozzle of the high-pressure water gun is aimed at the stain location, and the high-pressure water gun sprays high-pressure cleaning fluid to complete the cleaning operation of the photovoltaic panel at the location of the stain.

[0004] While the aforementioned device can effectively clean photovoltaic panels, its operation time is limited by the capacity of the water tank, which is required for operation. Furthermore, the water tank and the water it carries significantly increase the device's weight, leading to increased battery power consumption and consequently a substantial reduction in battery operating time. This necessitates frequent charging and refilling of the battery. Additionally, the lack of a protective device at the front of the propeller makes it susceptible to collisions with the object being cleaned, posing a safety hazard. Utility Model Content

[0014] This utility model also provides a cleaning device, including a water pump and a cleaning drone, wherein the water outlet of the water pump is connected to the water inlet connector via a hose.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0016] The cleaning drone and cleaning device provided by this utility model are equipped with an anti-collision mechanism, which can effectively prevent the object being cleaned from colliding with the propeller.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. Example 1

[0025] like Figure 1-5 As shown, a cleaning drone includes a body 1 with several propellers 101 on it, one of which is located at the front end of the body 1. A base frame 6 is located at the bottom of the body 1. A battery 5 is installed on the body. A spraying mechanism 2 is located below the body 1. The spraying mechanism 2 has a water inlet connector 202 and a water outlet connector 201. An anti-collision mechanism 3 is installed at the front end of the body 1, located in front of the propeller 101 at the front end of the body 1.

[0026] In this embodiment, the body 1 uses the technology employed in the body of an existing UAV, which is existing technology, including avionics system, control system, etc., which are well known to those skilled in the art and will not be specifically described here.

[0027] In this embodiment, there are two base frames 6, which are arranged opposite to each other. A fixing frame 405 is connected between the two base frames 6. A base plate 402 is fixedly connected to the fixing frame 405. Two clamping plates 401 are fixedly arranged opposite to each other on the base plate 402. A spraying mechanism 2 is fixedly connected between the two clamping plates 401. A water outlet connector 201 extends out of the front end of the two clamping plates 401, and a water inlet connector 202 extends out of the rear end of the two clamping plates 401.

[0028] The spraying mechanism 2 includes a valve 203. The inlet end 208 of the valve 203 is connected to the inlet connector 202, and the outlet end 207 of the valve 203 is connected to the outlet connector 201. The outlet connector 201 is connected to the quick-release connector 209, and the quick-release connector 209 is connected to the spray pipe 204. The spray pipe 204 is equipped with nozzles 206. The axial direction of the inlet connector 202 is set at an angle to the axial direction of the outlet connector 201, which can be an obtuse angle. The spray pipe 204 can be equipped with different lengths and different specifications such as bends and straight pipes, which can be selected according to the specific cleaning situation.

[0029] A valve core is slidably mounted inside the valve 203. One end of the valve core is provided with an elastic element, specifically a compression spring, between it and the inner wall of the valve. The other end of the valve core is connected to the valve stem 205, which extends out of the valve 203. A servo motor 403 is fixedly mounted on the clamping plate 401. The servo motor 403 is provided with a first swing arm 4031. A second swing arm 406 is hinged on the clamping plate 401 between the servo motor 403 and the valve stem 205. The first swing arm 4031 and the second swing arm 406 cooperate. Specifically, one end of the second swing arm 406 is a hinged end, and the other end is a free end. When the first swing arm 4031 swings, it will squeeze the free end of the second swing arm 406 to make it swing.

[0030] When the servo motor 403 rotates in the forward direction, it drives the first swing arm 4031 to swing in the forward direction. The first swing arm 4031 presses against the free end of the second swing arm 406 and causes it to swing. The free end of the second swing arm 406 presses against the valve stem 205. The valve stem 205 moves into the valve 203 and presses against the elastic element, thus closing the valve 203. When the servo motor 403 rotates in the reverse direction, it drives the first swing arm 4031 to swing in the reverse direction. The first swing arm 4031 disengages from the second swing arm 406. Under the elastic force of the elastic element, the elastic element presses against the valve stem 205, causing the valve stem 205 to move towards extending out of the valve 203. At the same time, it presses the second swing arm 406 back to its original position, thus opening the valve 203.

[0031] In this embodiment, several fixing blocks 404 are fixedly connected to the outer sides of both clamping plates 401 by fasteners. The fixing blocks 404 are fixedly connected to the base plate 402 by fasteners, specifically fastening bolts. Several fixing posts 4011 are respectively provided on both sides of the outlet connector 201 and the inlet connector 202 between the two clamping plates 401. Notches 2031 for accommodating the valve 203 are provided on the two clamping plates 401 at the positions corresponding to the valve 203. The two clamping plates 401 cooperate with the fixing posts 4011 to fix and install the valve 203, the inlet connector 202 and the outlet connector 201.

[0032] In this embodiment, the anti-collision mechanism 3 includes a support rod 301. One end of the support rod 301 is fixedly connected to the body 1, and the other end of the support rod 301 is fixedly connected to a first anti-collision beam 302. A second anti-collision beam 304 is provided above the first anti-collision beam 302. The first anti-collision beam 302 and the second anti-collision beam 304 are fixedly connected by a connecting rod 303. The second anti-collision beam 304 is higher than the propeller 101 at the front end of the body 1. Both the first anti-collision beam 302 and the second anti-collision beam 304 are arc-shaped, with the middle part of the arc protruding forward and located in front of the rotation range of the propeller 101 at the front end of the body 1. This prevents the propeller 101 from colliding with the object to be cleaned when the drone moves during the cleaning process.

[0033] In this embodiment, an illuminator 8 for illumination is fixedly connected to the front end of the body 1, and a sensor 7 for detecting obstacles is fixedly connected to the front end of the mounting bracket 405 to detect the position of the object to be cleaned. This sensor works in conjunction with the control system on the body 1 to facilitate the control of the drone's flight for precise cleaning. Example 2

[0034] like Figure 1 As shown, the cleaning device includes the cleaning drone and water pump 9 in embodiment 1. The water outlet of the water pump 9 is connected to the water inlet connector 202 through a hose 901. In actual use, the water pump is connected to a container for holding cleaning fluid.

[0035] When using the cleaning device provided by this utility model, the outlet end of the water pump 9 is connected to the inlet connector 202 through the hose 901. A suitable spray pipe 204 is installed on the outlet connector 201. The cleaning drone is controlled to fly to the location of the object to be cleaned, the water pump 9 is controlled to run, and the cleaning liquid is delivered to the spraying mechanism. The servo motor on the cleaning drone is controlled to run, and the valve is opened so that the cleaning liquid is sprayed onto the object to be cleaned. After the cleaning is completed, the water pump is controlled to stop running, and the servo motor is controlled to reverse to close the valve.

[0036] This embodiment is equipped with an anti-collision mechanism 3 to prevent the object being cleaned from coming into contact with the propeller 101 and causing damage to the propeller 101 and the object being cleaned. It eliminates the need for a water tank, making the cleaning drone lightweight, which helps to extend the operation time, avoids frequent battery replacements, and improves cleaning efficiency.

[0037] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
