[0002] Power grid inspection refers to the process of inspecting the operation of line equipment in detail along the line during power grid work, promptly discovering defects and fault points in the equipment, and promptly handling and solving them to ensure the stable operation and work of the power grid.

[0003] During the inspection process, the inspection robot needs to raise and lower the camera to record the surrounding environment. At the same time, the inspection robot also needs to detect the surrounding environment through obstacle avoidance sensors to avoid interference with obstacles. However, the obstacle avoidance sensors of existing inspection robots are usually fixed. When the inspection robot's camera rises to a certain height, the obstacle avoidance sensor cannot detect the real-time environment at a high position, and the camera may collide with obstacles.

[0021] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0022] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides a camera lifting device for an inspection robot, including a base 1, a lifting unit 2, and a camera 3.

[0025] The base 1 is installed on the inspection robot, the lifting unit 2 is installed on the base 1, the camera 3 is installed on the lifting end of the lifting unit 2, the fixed end of the lifting unit 2 is installed with a first obstacle avoidance sensor 4, and the lifting end of the lifting unit 2 is installed with a second obstacle avoidance sensor 5.

[0026] Based on the above structure, when high-position shooting is required, the camera 3 can be raised to a suitable position for shooting by raising the lifting end of the lifting unit 2, and at the same time, the second obstacle avoidance sensor 5 can be driven to rise synchronously, so that the second obstacle avoidance sensor 5 can detect the surrounding environment at a higher position, while the first obstacle avoidance sensor 4 can still detect the surrounding environment at a lower position. Double protection can effectively avoid collisions between the inspection robot and the outside world during movement.

[0027] In this embodiment, the lifting unit 2 may be a cylinder or a screw transmission mechanism as required.

[0028] For example, when the lifting unit 2 is a cylinder, the cylinder is extended and retracted vertically, and the camera 3 can be installed at the retracted end of the cylinder.

[0029] When the lifting unit 2 is a screw transmission mechanism, Figure 2-3As shown, the lifting unit 2 includes an outer cylinder 201, an inner cylinder 202, a motor 203, a screw rod 204, and a nut 205. The inner cylinder 202 and the outer cylinder 201 are both vertically arranged, the inner cylinder 202 is slidably sleeved inside the outer cylinder 201, the motor 203 is installed at the bottom end of the outer cylinder 201, the power output end of the motor 203 is coaxially fixed with the screw rod 204, the nut 205 is threadedly connected to the screw rod 204, the nut 205 is fixedly connected to the inner cylinder 202, and the camera 3 is installed at the top of the inner cylinder 202.

[0030] The inner cylinder 202 is the lifting end of the lifting unit 2, and the outer cylinder 201 is the fixed end of the lifting unit 2. The motor 203 drives the screw rod 204 to rotate, so as to drive the inner cylinder 202 to move up and down, thereby driving the camera 3 to move up and down. At the same time, the outer cylinder 201 can play a protective role, preventing the outside world from interfering with the motor 203, the screw rod 204 and other components, thereby ensuring the stable operation of the device.

[0032] The guide sleeve 207 can slide up and down along the guide rod 206 , that is, the guide rod 206 limits the guide sleeve 207 , thereby effectively improving the stability of the inner cylinder 202 moving up and down.

[0033] The lifting unit 2 includes two guide rods 206 and two guide sleeves 207. The two guide sleeves 207 are respectively slidably mounted on the two guide rods 206. The two guide rods 206 can further improve the stability of the inner cylinder 202 moving up and down.

The four directions of front, back, left, and right can be detected at the same time, and the detection effect is better.

[0035] The lifting end of the lifting unit 2 is equipped with a second sensor support 7, that is, the top of the inner cylinder 202 is equipped with the second sensor support 7, and four second obstacle avoidance sensors 5 are installed on the second sensor support 7, and the four second obstacle avoidance sensors 5 are respectively oriented to the four directions of front, back, left, and right. The four directions of front, back, left, and right can be detected at the same time, and the detection effect is better.
