Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an inspection unmanned aerial vehicle with a gas leakage detection function. Background Art

[0002] With the rapid development of industrialization, gas leakage accidents occur frequently, posing a serious threat to personnel safety, environmental protection and production stability. Traditional gas leakage detection methods, such as manual inspections and fixed gas detectors, have problems such as low efficiency, limited coverage area and slow response speed. In recent years, the rapid development of drone technology has provided new solutions for gas leakage detection. Drones equipped with high-precision gas sensors can achieve remote, fast and flexible gas detection. However, when a drone is equipped with a gas leak detector for flight, the drone is pushed into the sky by the rotation of the rotor to generate a downward airflow. However, the downward airflow generated by the rotor is easy to disturb the air around the gas leak detector, which makes it easy to blow away the gas around the gas leak detector, making it impossible for the gas leak detector to accurately detect gas leaks, reducing the detection efficiency. Therefore, it is necessary to design a patrol drone with gas leak detection function. Utility Model Content

In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component can be enlarged or reduced.

Any obvious modifications or changes made to the utility model do not depart from the spirit and scope of the utility model.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model proposes a patrol drone with a gas leakage detection function, including a drone component 1, a protection component 2 and a gas detector 5. The drone component 1 includes a body 101 and a rotor arm 102. The gas detector 5 is fixedly installed at the bottom of the body 101, and the rotor arm 102 is fixedly installed on the outside of the body 101. The drone component 1 also includes a motor 103 and a propeller 104. The motor 103 is fixedly installed at one end of the rotor arm 102, and the propeller 104 is installed on the top of the motor 103. The propeller 104 is driven by the motor 103 to rotate to generate lift, which can drive the body 101 to fly. The gas leaked in the air can be detected by the gas detector 5, so that the signal of the detected gas leakage is generated to the terminal equipment on the ground, so that the staff can conveniently understand the gas leakage remotely;

[0023] A protection component 2 is provided on the outer side of the rotor arm 102. The protection component 2 includes an airflow guide cover 201 and an elastic guardrail 202. The airflow guide cover 201 is fixedly connected to the rotor arm 102. The motor 103 is located in the airflow guide cover 201, and the motor 103 can be protected by the airflow guide cover 201. An elastic guardrail 202 is fixedly installed on one side of the airflow guide cover 201. The elastic guardrail 202 is annular and corresponds to the propeller 104. Through the elastic effect of the elastic guardrail 202, it can be conveniently buffered when colliding with an object during flight. The impact force of the collision is reduced, and the propeller 104 can be effectively protected from damage. At the same time, the deformation of the elastic guardrail 202 during buffering will not affect the normal rotation of the propeller 104, avoiding the impact on the flight operation. The airflow guide cover 201 can guide the airflow around the propeller 104, and can effectively block the gas around the gas detector 5, so that the airflow generated by the propeller 104 will not blow away the gas around the gas detector 5, so that the gas detector 5 can more accurately detect the surrounding leaked gas, thereby improving the accuracy of the detection;

[0024] The landing gear assembly 3 is installed on the outer side of the airflow guide cover 201. The landing gear assembly 3 includes a sliding seat 301, a support ring 302 and an anti-sliding block 303. The sliding seat 301 is slidably installed on the outer side of the airflow guide cover 201. The protection assembly 2 also includes a slide groove 203. The airflow guide cover 201 and the sliding seat 301 are slidably installed through the slide groove 203. The sliding seat 301 can be limited by the slide groove 203 so that the sliding seat 301 can slide up and down along the slide groove 203. The bottom of the sliding seat 301 is fixedly installed with a support ring 302, and the bottom of the support ring 302 is equidistantly distributed with anti-sliding blocks 303. The support ring 302 can be synchronously moved up and down by sliding the sliding seat 301 up and down. By driving the support ring 302 to move downward, the support ring 302 can be extended out of the bottom of the airflow guide cover 201, which can play a supporting role during landing. By providing multiple groups of support rings 302, the semicircular ring shape of the support ring 302 can be used to effectively increase the support range, which can avoid the situation where the ground is uneven during landing and cause tilting and tipping. At the same time, during the flight, the support ring 302 can be driven to move upward to shrink, which can avoid affecting the flight operation and effectively improve the use effect.

[0025] A driving assembly 4 is installed between the support ring 302 and the rotor arm 102. The driving assembly 4 includes a driving rod 401 and an active joint 402. The driving rod 401, the rotor arm 102 and the support ring 302 are all movably connected through the active joint 402. The driving rod 401 can be an electric push rod or a hydraulic push rod, which can enable the driving rod 401 to be extended and retracted. The support ring 302 can be pushed up and down by the extension and retraction of the driving rod 401. The active joint 402 can enable the driving rod 401 to perform corresponding flipping activities when it is extended and retracted to avoid motion interference. The drone assembly 1 also includes a mounting seat 105. The mounting seat 105 is fixedly installed on the bottom of the body 101. The mounting seat 105 and the gas detector 5 are fixedly connected through the mounting plate 501. The mounting plate 501 and the mounting seat 105 can be fixed by using bolts, so that the gas detector 5 can be conveniently installed on the bottom of the body 101, so that the gas detector 5 can conveniently detect the gas in the air below during flight.

[0026] The working principle of the inspection drone with gas leakage detection function based on the embodiment is: the propeller 104 is driven to rotate by the motor 103, which can drive the body 101 to fly into the air, and the gas detector 5 can detect the gas in the air. During the flight, the airflow of the propeller 104 can be isolated by the airflow guide cover 201 to blow away the gas around the gas detector 5, so that the gas detector 5 can accurately detect the leaked gas. The propeller 104 can be protected by the elastic guardrail 202 in the event of a collision, thereby improving the safety effect during flight. When the driving rod 401 is contracted, the support ring 302 can be driven to move upward to avoid affecting the flight. The sliding seat 301 can slide along the slide groove 203, so that the support ring 302 can move up and down stably. When landing, the extension of the driving rod 401 can push the support ring 302 to move downward and extend out of the bottom of the airflow guide cover 201, so that it can be supported during landing and can adapt to uneven ground. The anti-sliding block 303 can increase the friction between the ground and avoid sliding.
