Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle inspection, in particular to an emergency jetting treatment device for unmanned aerial vehicle transmission line inspection. Background Art

[0002] Drone inspection refers to the use of drones to conduct inspection and surveillance activities in various areas or facilities. It can acquire data by carrying various sensors and cameras, and then use image processing, machine learning, artificial intelligence and other technologies to analyze and interpret the data, thereby reducing the manpower requirements for manual inspections in harsh environments.

[0003] After searching, Chinese patent announcement number: CN215155655U discloses an emergency spraying treatment device for UAV power line inspection. The device uses a spray power device to spray the fire extinguishing agent inside the storage bin toward the fire point. The fire extinguishing agent covers the cable to achieve the fire extinguishing and first aid effect. A micro motor is arranged inside the diffusion device. The micro motor drives the connecting rod to rotate, and a water retaining plate at one end of the connecting rod rotates accordingly. When the water retaining plate corresponds to the spraying pipe, the fire extinguishing agent is spread out in a dispersed state and can cover a large area. When the water retaining plate does not correspond to the spraying pipe, the fire extinguishing agent is in a direct current state, which is highly targeted at the fire point and has a good emergency effect. In addition, two different fire extinguishing methods can be selected according to the scope of the fire.

[0004] However, in actual use, since the internal fire extinguishing agent is directly driven by the injection power device to be sprayed out, the contact amount between the fire extinguishing agent and the air is small during the spraying process, making it difficult to fully diffuse during the spraying process. Therefore, an unmanned aerial vehicle transmission line inspection emergency injection processing device is proposed to solve the above problem. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment: an emergency spraying treatment device for UAV power transmission line inspection, comprising a UAV 1, a fire extinguishing agent tank 4 is threadedly connected to the lower end of the UAV 1, a spraying mixing device 2 is arranged outside the fire extinguishing agent tank 4, and a dust blocking device 3 is arranged inside the spraying mixing device 2.

[0034] The jet mixing device 2 includes an air pump 201, a connecting pipe 202 is fixedly connected to the air outlet of the air pump 201, a transfer pipe 203 is fixedly connected to the end of the connecting pipe 202 away from the air pump 201, a guide pipe 204 is connected to the middle of the outer arc surface of the transfer pipe 203, a pressure relief valve 205 is fixedly connected to the end of the guide pipe 204 away from the transfer pipe 203, and a hollow pipe 206 is fixedly connected to the end of the transfer pipe 203 away from the connecting pipe 202.

[0035] A threaded groove is provided on the lower surface of the drone 1, so the fire extinguisher tank 4 can be installed and removed by rotating the thread. The outer surface of the air pump 201 is fixedly connected to the fire extinguisher tank 4 through a connecting frame, so the position stability of the air pump 201 during the flight of the drone 1 can be ensured. A through hole is provided at the lower end of the outer arc surface of the fire extinguisher tank 4, so that it can be connected to the pressure relief valve 205. The interior of the connecting pipe 202 is hollow, and the middle diameter of the transfer pipe 203 is smaller than the diameter of its left and right ends. Therefore, when air flows through the transfer pipe 203, the flow velocity at the center will increase, while the pressure will decrease. The pressure relief valve 205 is low, so a certain pressure difference can be generated at both ends of the pressure relief valve 205. A through hole is provided in the middle of the outer arc surface of the transfer pipe 203, so it can be connected with the guide pipe 204. A plurality of through holes are provided on the upper end of the outer arc surface of the hollow pipe 206, so that external air can flow into the hollow pipe 206. An impact plate 207 is fixedly connected to the lower end of the inner arc surface of the hollow pipe 206. The impact plate 207 is arranged in an inclined shape as a whole, so that the sprayed fire extinguishing agent can fully collide with it and will not be completely blocked. The end of the pressure relief valve 205 away from the guide pipe 204 is connected to the fire extinguishing agent tank 4.

[0036] Reference Figure 1 , Figure 4 as well as Figure 5The dust blocking device 3 includes a blocking plate 301, a fixed shaft 305 is fixedly connected to the inner side of the blocking plate 301, an outer shaft 304 is rotatably connected to the outer arc surface of the fixed shaft 305, a sealing plate 302 is fixedly connected to the outer arc surface of the outer shaft 304, and a limiting plate 303 is fixedly connected to the lower end of the blocking plate 301.

[0037] The outer arc surface of the blocking plate 301 is connected to the transfer tube 203, and a rectangular groove is provided on the inner side of the blocking plate 301, so that the outer shaft 304 and the sealing plate 302 can be accommodated therein. The outer arc surface of the fixed shaft 305 is elastically connected to the outer shaft 304 through a spiral spring, so that when there is no external force or a small external force, the sealing plate 302 can always be tightly attached to the limiting plate 303 due to the elastic force of the spiral spring. A through hole is provided at the center of the inner surface of the outer shaft 304, so that it can be rotatably connected to the fixed shaft 305. The lower end of the sealing plate 302 is set to an arc surface, so that it is not easy to cause motion interference with the transfer tube 203 when it rotates, and the outer surface of the limiting plate 303 is in contact with the sealing plate 302.

[0038] Working principle: During the use of this device, it is necessary to start the air pump 201 to drive the outside air to continuously enter the connecting pipe 202, pass through the transfer pipe 203 and finally be ejected from the hollow pipe 206. At the same time, when the gas flows through the middle of the transfer pipe 203, due to the narrow diameter in the middle, the gas flow rate here will be greater than the gas flow rate on both sides, so that the overall air pressure at the guide pipe 204 is reduced, and a certain air pressure difference is formed with the inside of the fire extinguishing agent box 4. At this time, the pressure relief valve 205 will release the fire extinguishing agent inside the fire extinguishing agent box 4 due to the increase in the air pressure difference on both sides, and drive it to continuously move into the hollow pipe 206 through the flow of air. At this time, since there are more impact plates 207 inside the hollow pipe 206, the ejected fire extinguishing agent can fully collide with the impact plates 207 and be dispersed, and the outside air will also flow into the hollow pipe 206, so that the ejected fire extinguishing agent can be evenly dispersed and ejected at least to the combustion area.

[0039] At the same time, when the device is used up, the volute spring will drive the outer shaft 304 to rotate through its own elastic force, and drive the sealing plate 302 to move toward the limit plate 303 and close to the surface of the limit plate 303, thereby sealing the rectangular groove area inside the blocking plate 301, thereby reducing the risk of a large amount of external dust entering the transfer tube 203 during the subsequent operation of the drone 1 and causing blockage in the smaller diameter area in the middle. During the startup of the air pump 201, since the pressure of the gas ejected by the air pump 201 is greater than the elastic force of the volute spring, the sealing plate 302 can rotate without hindering the normal ejection of the fire extinguishing agent.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
