Description

Technical Field

[0001] The utility model relates to the technical field of power line inspection, in particular to a camera device for UAV inspection. Background Technique

[0002] The inspection of transmission lines is an important link to ensure the normal operation of the power supply system. Its main purpose is to master the operation status of the lines and timely discover equipment defects and problems threatening the safety of the lines.

[0003] In the prior art, it is very common to use UAVs for transmission line inspection. The UAV cameras in the prior art are generally installed by a gimbal. Subsequently, the gimbal can drive the camera to rotate at a certain angle. However, generally, the shooting is carried out from a top-down perspective. Thus, when using a UAV for transmission line inspection and wanting to see the situation at the lower end of the cable, it is impossible to achieve it only by adjusting the gimbal. Therefore, an improved camera device for UAV inspection is needed to solve this problem. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a camera device for UAV inspection to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A camera device for UAV inspection, including a UAV body. At the four corners of the outer surface of the UAV body, extension rods are fixedly arranged. One end of each extension rod is fixedly provided with a motor. The output shaft end of the motor is fixedly provided with blades through a coupling. On one side of the surface of the UAV body, there is a shooting mechanism for observing the situation of the cable. The shooting mechanism includes a fixed ring, a connecting shaft, a connecting rod, and a camera. On one side of the surface of the UAV body, a fixed ring is fixedly arranged. In the middle of the inner side of the fixed ring, a connecting shaft is movably arranged through a bearing. One end of the connecting shaft is fixedly provided with a connecting rod. The end of the connecting rod away from the fixed ring is fixedly provided with a camera. On the outer surface of the connecting shaft, a worm gear is fixedly arranged. Inside the fixed ring, above the worm gear, a worm is movably arranged through a bearing. The worm gear and the worm are meshed with each other.

[0006] Preferably, a protective lens is fixedly arranged on the outer surface of the camera, which can protect the camera.

[0007] Preferably, the helix angle of the worm is smaller than the friction angle between the worm gear and the worm. In this way, self-locking can be formed between the worm gear and the worm. That is to say, only when the worm rotates can it drive the worm gear to rotate, thereby driving the connecting shaft, the connecting rod, and the camera to rotate. When the worm does not rotate, the angles of the worm gear, the connecting rod, and the camera can be automatically locked without other complex operations; to facilitate fixing the shooting angle of the camera.

[0008] Preferably, a motor is fixedly arranged on one side inside the fixed ring, and the output shaft end of the motor is in transmission connection with the worm through a coupling, so that the motor can conveniently drive the worm to rotate.

[0009] Preferably, a protective ring is fixedly arranged on the surface of the extension rod outside the blade, and the protective ring can play a role in protecting the high-speed rotating blade.

[0010] Preferably, support feet are fixedly arranged at the lower end of the extension rod, and the support feet can provide a stable supporting force for the whole device after it lands.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the motor drives the worm to rotate, so as to drive the worm gear to rotate, and then drive the connecting shaft and the connecting rod to rotate through the worm gear, so as to drive the camera to rotate. Specifically designed for power line inspection, the camera can take parallel shots, which is convenient for the staff to observe the side of the cable, and can also take upward shots, which is convenient for the staff to observe the lower end of the power line. And it can also take top-down shots as in the prior art. In this way, the shooting direction of the device can be significantly improved, facilitating the inspection work of the power line.

[0013] 2. When the worm rotates during the use of the present utility model, it can drive the worm gear to rotate, so as to drive the connecting shaft, the connecting rod and the camera to rotate. When the worm does not rotate, the angles of the worm gear, the connecting rod and the camera can be automatically locked without other complex operations, which is convenient for fixing the shooting angle of the camera.

[0022] The helix angle of the unfolded worm 9 is smaller than the friction angle of the contact between the worm gear 8 and the worm 9, so that self-locking can be formed between the worm gear 8 and the worm 9. That is to say, only when the worm 9 rotates can it drive the worm gear 8 to rotate, so as to drive the connecting shaft 14 and the connecting rod 6 and the camera 7 to rotate. When the worm 9 does not rotate, the angles of the worm gear 8 and the connecting rod 6 and the camera 7 can be automatically locked without other complex operations; to facilitate fixing the shooting angle of the camera 7;

[0025] The lower end of the extension rod 2 is fixedly provided with a support leg 13, and the support leg 13 can provide a stable supporting force for the whole device after it lands on the ground.

[0026] Working principle: When using this device, the device drives the blade 4 to rotate at high speed through the motor, so as to drive the whole device to fly up. At this time, the camera 7 can conveniently take pictures of the cable situation. The camera 7 of this device can rotate at multiple angles. The worm 9 is driven to rotate by the motor 11, so as to drive the worm gear 8 to rotate, and then the connecting shaft 14 and the connecting rod 6 can be driven to rotate by the worm gear 8, so as to drive the camera 7 to rotate. Specifically designed for power line inspection, the camera 7 can take parallel pictures, so as to facilitate the staff to observe the side of the cable, and can also take pictures upward, so as to facilitate the staff to observe the lower end of the power line, and can also take top-down pictures as in the prior art.
