AI Technical Summary
Existing drone inspection devices lack a structure for adjusting the shooting angle of the inspection camera, making it impossible to shoot from different positions while hovering, and they also lack effective cushioning, shock absorption, and protective measures.
An inspection device based on a drone was designed. The camera angle is adjusted by adjusting the rotating plate and adjusting the lead screw system. The drone's shock absorption effect is achieved by using a buffer sleeve and a damper. The buffer sleeve with support legs and telescopic springs is designed to achieve shock absorption. A protective plate is set on the fan blade support to prevent collision.
It enables flexible adjustment of the camera angle during hovering, improving the applicability of inspection, and enhances the practicality and reliability of the device through buffering, shock absorption, and protective measures.

[0002] Inspection drones are unmanned aerial vehicles equipped with advanced monitoring devices, designed specifically for remote monitoring and data analysis. They provide real-time, high-resolution images and data, making them an important tool for modern inspection work. In today's rapidly developing intelligent era, inspection drones, as a cutting-edge technology, are quietly changing the way industrial inspection and urban management are conducted.
[0003] A search revealed that CN215217664U discloses a cable channel inspection device based on a drone, comprising: a drone body with impeller supports on both sides, a motor on one side of the impeller supports, and an impeller on the output shaft of the motor; multiple protection devices, which are respectively located on the side of the impeller supports away from the drone body, on both sides of the impeller supports and the motor, and on the side of the impeller away from the motor; each protection device includes a protection rod, a spring, and a buffer head connected in sequence.
[0004] The prior art document describes a drone-based cable tunnel inspection device that, while enabling cable tunnel inspection through lighting and preventing collisions with tunnel walls through anti-collision devices, lacks a structure for adjusting the camera's shooting angle, thus failing to capture images of different locations while hovering.
[0005] To address this, we propose an inspection device based on unmanned aerial vehicles (UAVs). Utility Model Content
[0006] The present invention aims to solve the technical problems existing in the prior art and provide an inspection device based on unmanned aerial vehicles (UAVs).
[0007] To achieve the above objectives, this utility model adopts the following technical solution: an inspection device based on a drone, comprising a drone body, an adjustment plate at the bottom of the drone body, an inspection camera fixedly mounted at the bottom of the adjustment plate, first mounting plates on the left and right sides of the rear end of the adjustment plate, the top of each first mounting plate being fixedly mounted on the bottom of the drone body, a first rotating shaft rotatably inserted into the rear end of the adjustment plate, the left and right ends of the first rotating shaft being fixedly inserted into the left and right first mounting plates respectively, a second rotating shaft fixedly inserted into the front end of the adjustment plate, adjusting support rods rotatably mounted on the left and right ends of the second rotating shaft, an adjusting slider between the other ends of the two adjusting support rods, third rotating shafts fixedly mounted on the left and right sides of the adjusting slider, the other ends of the two adjusting support rods being rotatably mounted on the mutually distant ends of the two third rotating shafts, a limit rail fixedly mounted at the bottom of the drone body, and the adjusting slider slidably mounted on the limit rail.
[0008] Furthermore, a second mounting plate is provided on the front and rear sides of the adjusting slider, and the top of each second mounting plate is fixedly installed on the bottom of the drone body. An adjusting screw is provided on the lower side of the limiting slide rail. The front and rear ends of the adjusting screw are respectively rotatably inserted into the front and rear second mounting plates. An adjusting sleeve is threaded on the adjusting screw, and the adjusting slider is fixedly mounted on the adjusting sleeve.
[0009] Furthermore, a drive motor is fixedly mounted on the rear of the second mounting plate at the rear end, and the rear end of the adjusting screw is mounted on the front output end of the drive motor via a rotating shaft.
[0010] Furthermore, buffer sleeves are fixedly installed at the four corners of the bottom of the drone body, and a support leg is slidably inserted into the bottom of each buffer sleeve.
[0011] Furthermore, a damper is provided between the top of each support leg and the bottom of the drone body. The upper and lower ends of the damper are fixedly installed on the bottom of the drone body and the top of the support leg, respectively, and a telescopic spring is sleeved on the damper.
[0012] Furthermore, fan blade brackets are fixedly installed on the left and right sides of each end of the front and rear of the drone body, and a connecting rod is fixedly installed at the opposite end of each pair of fan blade brackets. A protective plate is fixedly installed at the other end of each connecting rod.
[0013] This invention provides an inspection device based on a drone. It has the following beneficial effects:
[0014] 1. This UAV-based inspection device, in use, uses an inspection camera for inspection recording. Activating the drive motor rotates the adjusting screws mounted on two second mounting plates. The adjusting screws, through adjusting sleeves, drive the adjusting slider to slide backward along a limit rail. The adjusting slider, through an adjusting support rod between a third and second rotating shaft, drives an adjusting plate to rotate around a first rotating shaft. The adjusting plate then rotates the inspection camera mounted at its bottom to adjust the camera angle, achieving the effect of capturing targets at different angles during hovering. This facilitates the normal operation of inspection work and effectively improves the applicability of the device.
[0015] 2. This inspection device based on a drone, when the device descends at a high speed, after the bottom of the support leg contacts the ground, the buffer sleeve slides down along the support leg, compressing the damper set between the support leg and the drone body. In conjunction with the telescopic spring set on the damper, the buffering and shock absorption effect is achieved, avoiding damage to the body structure and effectively improving the practicality of the device.
[0016] 3. This drone-based inspection device has a protective plate installed on the fan blade support via a connecting rod to prevent damage to the fan blades during operation, ensuring that the device can complete the inspection work normally and efficiently, and further improving the practicality of the device.
