Description

TECHNICAL FIELD

[0001] The utility model relates to unmanned plane monitoring technical field, concretely is unmanned plane monitoring devices for gas pollution. BACKGROUND

[0002] Unmanned aircraft is called "unmanned plane", which is a kind of unmanned plane controlled by radio remote control equipment and self-provided program control device. There is no cockpit on the plane, but there are devices such as autopilot and program control device. When it is recovered, it can be automatically landed in the same way as the landing process of ordinary aircraft, or it can be recovered by parachute or net through remote control. Because the unmanned plane has a short flight preparation time, it can quickly carry equipment for flight, and then a large number of manufacturers have designed unmanned plane equipment for detecting gas pollution.

[0003] Downwash, also known as rotor downwash, refers to the induced velocity generated by the rotation of the rotor when the helicopter is in hovering state. The induced velocity and the blade element circumferential motion velocity form the blade true velocity, which makes the air flow in the opposite direction of the pulling force. Under this condition, the pressure on the upper surface of the rotor is small, and the pressure on the lower surface is large, which generates lift between the upper and lower surfaces of the rotor. Because the height of the helicopter does not change during flight, the air with large pressure on the lower surface will flow downward, forming downwash.

[0004] The existing unmanned plane monitoring device for gas pollution generally adopts the method of directly installing an air detection device on the top of the unmanned plane. However, when detecting gas leakage in a narrow alley, the unmanned plane will generate downwash during flight. If there is a gas pipeline installation platform nearby, air flow may be bounced back, which may interfere with the detection effect and affect the accuracy of the detection. UTILITY MODEL CONTENT

[0005] Therefore, the utility model aims to provide an unmanned plane monitoring device for gas pollution to solve the technical problem that air flow bounceback may interfere with the detection effect and affect the accuracy of the detection.

[0012] Further, a side top of the air detector is provided with a socket, and the socket is matched with the plug.

[0013] By adopting the technical scheme, the socket matched with the plug is arranged at the side top of the air detector, thereby providing a direct interface for power connection of the air inlet fan, enabling the air inlet fan to be directly connected with the air detector through the plug, and simplifying arrangement and connection mode of the power cord.

[0014] Further, the clamping grooves are arranged in an L-shaped structure, and two clamping grooves are arranged in a ring shape and uniformly arranged.

[0015] By adopting the technical scheme, the clamping grooves are arranged in an L-shaped structure, thereby providing a stable support mode for mounting the air inlet fan, the L-shaped clamping grooves can ensure that the air inlet fan has sufficient stability and support force after being mounted, thereby preventing the air inlet fan from shaking or falling off during flight, and thereby ensuring normal operation of the monitoring device.

[0016] Further, a flexible rod is arranged between the horn mouth and the air detector, and the flexible rod and the bellows are located in the same vertical plane.

[0017] By adopting the technical scheme, the flexible rod is arranged between the horn mouth and the air detector, the flexible rod has certain bending and torsion capacity, it can adapt to different environments and flight conditions, and the position of the horn mouth can be freely adjusted.

[0018] Further, the flexible rod is made of plastic material.

[0019] By adopting the technical scheme, the flexible rod is made of plastic material, the weight of the whole monitoring device is reduced, the plastic material is lighter than metal and other materials, which helps to reduce the load of the unmanned aerial vehicle and improve the flight efficiency and endurance.
