Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and particularly to a vertical takeoff and landing multi-rotor unmanned aerial vehicle platform equipped with a life detection device. Background Technique

[0002] An unmanned aerial vehicle is simply referred to as a "drone". A drone is an unpiloted aircraft controlled by a radio remote control device and a self-provided program control device, or is completely or intermittently autonomously operated by an on-vehicle computer. Compared with a piloted aircraft, drones are often more suitable for tasks that are too "stupid, dirty or dangerous". When drones are used for search and rescue operations, they need to be equipped with life detection devices to search for trapped persons. Any object with a temperature above absolute zero will emit infrared radiation, and the human body is also a natural infrared radiation source. However, the infrared radiation characteristics of the human body are different from those of the surrounding environment. The infrared life detector uses the difference between them to separate the target to be searched from the background in the form of imaging, so as to achieve the purpose of finding trapped persons.

[0003] After retrieval, the patent publication number CN113064163B discloses a drone equipped with a life detection device and a detection method. The detection device includes a sky-end detection radar device and a display control device at the ground end. The sky-end detection radar device includes an antenna, a radio frequency module, and a baseband processing module; the radio frequency module includes a digital frequency synthesizer or a phase-locked loop, a power amplifier, a circulator, a low-noise amplifier, a combiner, a mixer, a band-pass filter, a gain controllable amplifier, a limiter, an analog-to-digital converter, and an antenna. The digital frequency synthesizer or the phase-locked loop, the power amplifier, the circulator, and the antenna constitute a transmission channel; the antenna, the circulator, the low-noise amplifier, the combiner, the mixer, the band-pass filter, the gain controllable amplifier, the limiter, and the analog-to-digital converter constitute a reception channel. The detection device of the present invention is small in size and light in weight, and is carried on a drone to achieve large-area and rapid detection of trapped persons, and has stronger environmental adaptability and application.

[0004] During the use of existing drones, due to the uneven ground on site, after the drone lands on the ground, the detection device will collide with the ground, which will cause damage to the detection device and affect the service life of the detection device. Summary of the Invention

[0005] The purpose of the present invention is to provide a vertical takeoff and landing multi-rotor unmanned aerial vehicle platform equipped with a life detection device to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: a vertical take-off and landing multi-rotor UAV platform equipped with a life detection device, including a UAV body, a connecting cover, a sleeve, a hinge and a cylinder body. One side of the outer wall of the lower end of the UAV body is installed with a connecting cover. First card sleeves are installed on both outer walls of the connecting cover. A cylinder body is rotatably installed inside the first card sleeve. Hinges are installed at the lower ends of both outer walls of the connecting cover, and a protective cover is connected to the connecting cover through the hinges. Sleeves are installed on both sides of the outer wall of the lower end of the UAV body.

[0007] When using a vertical take-off and landing multi-rotor UAV platform equipped with a life detection device in this technical solution, after the UAV body is driven by the rotor body to fly off the ground, the air pump body extracts the gas inside the sleeve and transports it to the inside of the cylinder body through the connecting pipe. The negative pressure state inside the sleeve causes the piston body to move vertically inside the sleeve, achieving the purpose of storing the connecting rod, thereby reducing the overall volume of the device, reducing the wind resistance when the UAV body flies, improving the flight smoothness of the UAV body, and after the gas enters the inside of the cylinder body, one end of the cylinder body extends, thereby driving the protective cover to rotate circumferentially through the second card sleeve, exposing the detection device body, enabling the detection device body to be used normally, and the protective cover achieves the purpose of protecting the detection device body.

[0008] Preferably, rotor bodies are installed on the outer wall of the UAV body in a rectangular array distribution. The rotor bodies can drive the UAV body to move, thereby achieving the purpose of driving the UAV body to fly.

[0009] Preferably, a pan-tilt body is installed on one side of the outer wall of the lower end of the UAV body. The pan-tilt body is located inside the connecting cover;

[0010] A detection device body is installed inside the pan-tilt body. The detection device body can detect trapped persons, and the pan-tilt body can adjust the detection angle of the detection device body to ensure the comprehensiveness of the detection of the detection device body.

[0011] Preferably, a second card sleeve is installed at the lower end of one side of the outer wall of the protective cover. One end of the cylinder body is rotatably installed inside the second card sleeve. During the telescopic process of the cylinder body, it can drive the protective cover to rotate circumferentially through the hinge, thereby exposing the inside of the connecting cover.

[0012] Preferably, silica gel pads are fixedly attached to the outer walls of the two protective covers. One side outer wall of the silica gel pad is in contact with the lower end outer wall of the connecting cover. The silica gel pad ensures the sealing between the protective cover and the connecting cover and ensures the shielding effect on the inside of the connecting cover.

[0013] Preferably, an air pump body is installed on one side of the upper end of the inner wall of the sleeve. A connecting pipe is inserted and installed on the outer wall of one side of the air pump body. The connecting pipe penetrates through the sleeve and is communicated with the cylinder body. The air pump body transports the gas inside the sleeve to the inside of the cylinder body, so that the cylinder body expands and contracts.

[0014] Preferably, a piston body is arranged at the lower end inside the sleeve. The outer wall of the piston body is in contact with the inner wall of the sleeve, which can ensure the sealing performance between the sleeve and the piston body.

[0015] One side of the outer wall of the lower end of the piston body is provided with a connecting rod. The connecting rod penetrates through one end of the outer wall of the sleeve and is provided with a support plate. The sleeve can accommodate the connecting rod, reduce the wind resistance of the UAV body, and ensure the smoothness of the UAV body during flight.

[0016] Preferably, the size after the two protective covers are in contact is consistent with the size of the connecting cover.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the connecting cover, the protective cover and the sleeve, the present invention achieves the effect of protecting the detection device body. The air pump body extracts the gas inside the sleeve and transports it to the inside of the cylinder body through the connecting pipe, so that the piston body moves vertically inside the sleeve, achieving the purpose of accommodating the connecting rod, thereby reducing the overall volume of the device, reducing the wind resistance of the UAV body during flight, and improving the flight smoothness of the UAV body. After the gas enters the inside of the cylinder body, one end of the cylinder body extends, thereby driving the protective cover to rotate circumferentially through the second ferrule, exposing the detection device body and enabling the detection device body to be used normally. The protective cover achieves the purpose of protecting the detection device body, avoiding damage to the detection device body during takeoff and landing, and ensuring the service life of the detection device body.
