Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a distance measuring device for an unmanned aerial vehicle of a transmission line. Background Technique

[0002] With the rapid development of social economy and the accelerating pace of urbanization, the demand for electricity in all walks of life is increasing. Therefore, a national interconnected power grid with ultra / extra-high voltage transmission lines as the main framework has emerged as the times require. However, due to the rapid expansion of the power grid scale and voltage level, the ultra / extra-high voltage transmission lines have high voltage levels, long transmission distances, taller towers than before, and more complex terrains to cross. The planning of line routes and the layout of tower positions are becoming more and more complex. Therefore, in the power system, the transmission line is an indispensable part connecting the power station and users. Ensuring its safe and stable operation is crucial for the entire power grid.

[0003] After a natural mountain fire disaster occurs, the mountain fire will affect the transmission line and cause a power outage. Due to the unclear situation and complex terrain, it is impossible to measure the distance of the affected transmission line manually. Therefore, in order to solve the above problems, unmanned aerial vehicles are currently used for patrol inspection and measurement. The unmanned aerial vehicle can quickly measure the distance of the affected transmission line, evaluate the damage degree, and provide data support for the repair work. Through the data measured by the unmanned aerial vehicle, the emergency response team can quickly formulate a specific repair plan, reduce the power outage time, and restore the power supply capacity of the power grid as soon as possible;

[0004] However, after the mountain fire is over, when using an unmanned aerial vehicle to measure the distance of the affected transmission line, the high temperature generated by the mountain fire will form a strong updraft, which will affect the flight stability and safety of the unmanned aerial vehicle. Moreover, the high-temperature updraft contains soot and dust, which will cover the measurement sensor lens of the unmanned aerial vehicle, resulting in inaccurate measurement. Content of the Utility Model

[0005] The purpose of the utility model is to provide a distance measuring device for an unmanned aerial vehicle of a transmission line to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A distance measuring device for an unmanned aerial vehicle of a transmission line includes a four-wheel drive unmanned aerial vehicle, an integrated cooling and protection component, and a cleaning component for cleaning the outside of the distance measuring lens of the four-wheel drive unmanned aerial vehicle. The four-wheel drive unmanned aerial vehicle includes an unmanned aerial vehicle body and spiral blades connected around the unmanned aerial vehicle body;

[0008] The integrated cooling and protection component includes a cooling water tank, an integrated collision protection and cooling frame, and a four-way pipe. The cooling water tank is located at the top of the unmanned aircraft body. The integrated collision protection and cooling frame is arranged in a circular ring structure and is distributed outside each of the spiral blades. One side of the integrated collision protection and cooling frame is connected to the outer wall of the unmanned aircraft body. A number of cooling water outlet holes are uniformly and penetratingly formed at the bottom of the integrated collision protection and cooling frame. A cooling water inlet is penetratingly arranged at the top of the integrated collision protection and cooling frame near the unmanned aircraft body side.

[0009] As a preferred solution of the present utility model, a delivery pump is arranged on the inner wall of the cooling water tank. The water inlet of the delivery pump extends into the cooling water tank through a pipeline. The water outlet of the delivery pump is connected to the top of the four-way pipe in a penetrating manner. The four water outlets of the four-way pipe are respectively connected to the cooling water inlets close to them in a penetrating manner.

[0010] As a preferred solution of the present utility model, a cooling and heat conduction aluminum plate is arranged at the bottom of the cooling water tank, and the cooling and heat conduction aluminum plate abuts against the top shell of the control main board inside the unmanned aircraft body.

[0011] As a preferred solution of the present utility model, the cleaning component includes a protective shell located outside the distance measurement lens. A cleaning rod is arranged outside the protective shell. A cleaning plate wiper is clamped on the cleaning rod. One end of the cleaning rod away from the cleaning plate wiper is connected to a cleaning motor, and the cleaning motor is embedded on the unmanned aircraft body inside the protective shell.

[0012] As a preferred solution of the present utility model, the delivery pump is electrically connected to the control main board inside the unmanned aircraft body through a wire.

[0013] As a preferred solution of the present utility model, the cleaning motor is electrically connected to the control main board inside the unmanned aircraft body through a wire.

[0014] As a preferred solution of the present utility model, the integrated collision protection and cooling frame is a hollow structure with a through interior.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. In view of the problems raised in the background art, when measuring the distance of the affected transmission lines by drones after a wildfire occurs, the strong updrafts caused by the high temperature generated by the wildfire, as well as the accompanying smoke and dust, affect the flight stability and measurement accuracy of the drones. In this application, an integrated collision protection and cooling frame is connected to the outside of the spiral blades of the drone body. On the one hand, the integrated collision protection and cooling frame prevents the spiral blades from colliding with other objects during flight, which may affect stability or cause a crash. On the other hand, the integrated collision protection and cooling frame has a hollow structure with a through hole at the bottom, and a water spraying method is set around the bottom of the drone body. During flight, water mist can be sprayed onto the ground or into the air. When the water evaporates, it can absorb heat, thereby theoretically reducing the air temperature and weakening the intensity of the updrafts. At the same time, the water mist can capture dust and smoke in the air, reduce the pollution of the sensor lens, and the weakened updrafts can reduce the disturbance of the drone during flight, improving flight stability and safety.

[0017] 2. By setting a protective shell outside the distance measurement lens, dust and smoke are prevented from entering the inside of the distance measurement lens. By setting a cleaning rod and a cleaning plate outside the protective shell to clean the protective shell outside the distance measurement lens, it is beneficial to improve the accuracy of data measurement.

[0018] 3. A cooling and heat conduction aluminum plate is set on the shell of the control main board inside the drone body. The top of the cooling and heat conduction aluminum plate abuts against the bottom of the cooling water tank. The cooling water in the cooling water tank is used in cooperation with the cooling and heat conduction aluminum plate to cool the control main board inside the drone body, preventing the components inside the drone body from overheating and affecting the operation efficiency of the drone and the service life of the electronic components. Through this cooling system, the operation stability and safety of the drone in a high-temperature environment can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Furthermore, when measuring the distance of the affected power transmission line by the drone after a wildfire occurs, the strong updraft caused by the high temperature generated by the wildfire, as well as the accompanying soot and dust, will cover and contaminate the sensor lens. By providing a protective shell 31 outside the distance measurement lens, it is possible to prevent dust and soot from entering the inside of the distance measurement lens.

[0030] Please refer to Figure 2 , 3And 4, the integrated cooling and protection component 2 includes a cooling water tank 21, an integrated collision protection and cooling frame 22, and a four-way pipe 23.

A cooling water inlet 222 is throughly arranged near one side of the unmanned aircraft body 11 at the top of the integrated collision protection and cooling frame 22; a delivery pump 24 is arranged on the inner wall of the cooling water tank 21. The water inlet of the delivery pump 24 extends into the interior of the cooling water tank 21 through a pipeline. The water outlet of the delivery pump 24 is connected to the top of the four-way pipe 23 throughly. The four-way pipe 23 is fixed at the bottom of the unmanned aircraft body 11 between the four integrated collision protection and cooling frames 22.

The cooling and heat conduction aluminum plate 211 abuts against the top shell of the control main board inside the unmanned aircraft body 11; the delivery pump 24 is electrically connected to the control main board inside the unmanned aircraft body 11 through a wire.

[0031] It should be noted that in this embodiment, by connecting and arranging the integrated collision protection and cooling frame 22 outside the spiral blade 12 of the unmanned aircraft body 11, on the one hand, the integrated collision protection and cooling frame 22 prevents the spiral blade 12 from colliding with other objects during flight, which may affect stability or cause a crash problem. On the other hand, the integrated collision protection and cooling frame 22 is a hollow structure with a through interior, and cooling water outlet holes 221 are throughly opened at the bottom.

[0033] Furthermore, a cooling and heat conduction aluminum plate 211 is arranged on the shell of the control main board inside the unmanned aircraft body 11. The top of the cooling and heat conduction aluminum plate 211 abuts against the bottom of the cooling water tank 21. The cooling and heat conduction aluminum plate 211 cooperates with the cooling water inside the cooling water tank 21 to cool the control main board inside the unmanned aircraft body 11, preventing the components inside the unmanned aircraft body 11 from overheating, which may affect the operation efficiency of the drone and the service life of the electronic components. Through this cooling system, the operation stability and safety of the drone in a high-temperature environment can be improved.

The cooling water is cooled through the cooling water outlet holes 221 at the bottom of the integrated collision protection and cooling frame 22, and the water mist is sprayed to capture dust and soot in the air, reducing the pollution of the sensor lens. The weakened updraft can reduce the disturbance of the drone during flight, improving the flight stability and safety. The controller controls the cleaning motor to drive the cleaning plate 312 on the cleaning rod 311 to clean the soot and dust outside the protective shell 31. According to the known power transmission line layout and the scope of fire impact, pre-plan the flight route of the drone to maximize the coverage area and ensure safety. Before actual flight, predict the performance of the drone on the predetermined route through simulation software and adjust the flight plan to cope with possible airflow instability and other dangers. During the flight process, the operator monitors the flight data and video feed of the drone in real time, and is ready to adjust the flight parameters or path at any time to adapt to the actual situation, ensuring that all collected data is accurately recorded, including video recordings, photos and 3D scan data. Use software to process the collected images and scan data to generate an accurate 3D model of the damaged area, analyze the specific damage situation, and compile a detailed report based on the analysis results, outlining the damage degree of the power transmission line, the areas that need to be repaired and the recommended repair measures. The report should include all key data and high-definition images to support decision-making.

At this time, the internal controller controls the delivery pump 24 to work. The delivery pump 24 conveys the cooling water located in the cooling water tank 21 to the inside of the four-way pipe 23 through a pipeline, and conveys the cooling water to the inside of the integrated collision protection and cooling frame 22 through the four-way pipe 23. Cooling water cooling is carried out through the cooling water outlet holes 221 at the bottom of the integrated collision protection and cooling frame 22. The sprayed water mist captures dust and soot in the air, reduces the pollution of the sensor lens, and the weakened updraft can reduce the disturbance suffered by the drone during flight, improving the flight stability and safety. The controller controls the cleaning motor to drive the cleaning plate 312 on the cleaning rod 311 to clean the soot and dust on the outside of the protective shell 31.
