[0002] When using a high-definition camera, a height adjustment device is often used to capture a wider range of images, so that the specific conditions of objects can be observed more clearly. However, the existing automatic height adjustment device for high-definition cameras still has certain defects, such as:

[0004] The above-mentioned height-adjustable camera can accurately adjust the height of the camera by means of a sliding block hinged on the push rod. However, when using the device, if the height adjustment position of the camera is not properly controlled, collision is likely to occur, and the camera is easily damaged when it collides. Utility Model Content

[0005] The utility model aims to provide an automatic height adjustment device for a high-definition camera, so as to solve the problem in the above background technology that if the height adjustment position is not properly controlled, collision is likely to occur, and the camera is easily damaged when the collision occurs.

[0006] To achieve the above object, the utility model provides the following technical solutions: an automatic height adjustment device for a high-definition camera, comprising a main box and a fixed rod fixedly installed at the lower end of the main box, wherein a lifting rod is nested inside the fixed rod, and a junction box is arranged at the lower end of the lifting rod, and the lower end of the junction box is connected to the high-definition camera through a ball camera mounting flange, and an obstacle avoidance sensor is installed on the right bolt of the junction box;

[0007] A servo motor is fixedly installed inside the fixed rod, and an automatic adjustment dust removal mechanism is provided at the output end of the servo motor;

[0008] A return spring is fixedly installed at the lower end of the lifting rod, and a junction box is fixedly installed at the lower end of the return spring, and a shock-absorbing protection mechanism is arranged between the lifting rod and the junction box.

[0009] Furthermore, a mounting hole is fixedly installed at the upper end of the main box, and the main box can be bolted to the lower end of the working position through the mounting hole.

[0010] Furthermore, the automatically adjustable dust removal mechanism is provided with a threaded rod, and the upper end of the threaded rod is fixedly mounted on the output end of the servo motor, and a lifting rod is threadedly mounted on the surface of the threaded rod.

[0011] Furthermore, a limiting groove is provided on the inner side of the fixing rod, and limiting blocks are fixedly installed on the left and right sides of the upper end of the lifting rod, and the limiting blocks are connected to the limiting groove in a sliding manner.

[0012] Furthermore, an airbag is provided inside the fixing rod, and the airbag is located inside the limiting groove, and the airbag is elastically provided, and an air guide hose is installed through the outer side of the lower end of the airbag, an air outlet is installed through the lower end of the air guide hose, and the output end of the air outlet is aligned with the lower end of the high-definition camera, a one-way air inlet is installed through the inner side of the lower end of the airbag, and a one-way valve is provided inside the one-way air inlet.

[0013] Furthermore, the shock-absorbing protection mechanism is provided with a damping rod, and the upper end of the damping rod is fixedly mounted inside the lower end of the lifting rod, and the lower output end of the damping rod is fixedly mounted on the upper end of the junction box.

[0014] Furthermore, the lower end of the lifting rod is in the shape of a cross convex block, and the upper end of the junction box is in the shape of a cross concave block, and the lifting rod corresponds to the upper end of the junction box.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. It is equipped with mounting holes that can be installed conveniently. The main box bolts are installed in the corresponding working positions through the mounting holes, so that the fixing rod and the lifting rod at the bottom of the main box can be fixed together. At the same time, the high-definition camera is installed at the bottom of the lifting rod through the junction box. The high-definition camera is installed through a specific ball camera mounting flange, which can realize the monitoring of objects;

[0017] Furthermore, an obstacle avoidance sensor is arranged on the outside of the junction box. Through the arrangement of the sensor, it is possible to sense objects that the high-definition camera is about to contact, avoid collision with the high-definition camera, and give an early warning when the high-definition camera is about to collide;

[0018] 2. A threaded rod capable of adjusting the height of the lifting rod is arranged inside the fixed rod. When the height of the lifting rod and the high-definition camera needs to be adjusted, the servo motor is started to control the threaded rod to rotate. When the threaded rod rotates, it drives the lifting rod connected to the thread on its surface. The lifting rod is limited by the limit block and moves up and down along the limit groove, so that the height of the lifting rod and the high-definition camera at the bottom can be adjusted, which is convenient for capturing images at different positions;

[0019] Furthermore, when the height of the lifting rod is adjusted, the limit block slides along the limit groove to squeeze the airbag, and the airbag is squeezed to transport the internal air to the air outlet through the air guide hose, and the air outlet is aimed at the surface of the high-definition camera to blow out dust, which can effectively prevent dust from accumulating on the surface of the high-definition camera. At the same time, when the limit block rises and stops squeezing the airbag, the airbag expands due to its own elastic force, and the airbag after the collision is inflated through the one-way air inlet, so that it can be used multiple times, which can improve the cleaning effect and prevent the high-definition camera from being cleaned for a long time and dust accumulating on its surface to affect the image capture effect;

[0020] Furthermore, when the staff is unable to respond due to the induction of the obstacle avoidance sensor, the high-definition camera collides with the obstacle. When the high-definition camera is collided, pressure is applied to the junction box, and the junction box squeezes the reset spring upward. The reset spring is used for buffering to prevent the high-definition camera from being damaged by excessive force of hard collision. When the junction box rises, the shape of its upper end corresponds to the shape of the bottom of the lifting rod, which can prevent deviation. At the same time, a damping rod is arranged between the junction box and the lifting rod. The setting of the damping rod prevents the reset spring from vibrating back and forth due to elastic force after buffering. Therefore, the damping rod is required for shock absorption, thereby achieving further protection for the high-definition camera. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing rod 3 is provided with an air bag 13 inside, and the air bag 13 is located inside the limiting groove 12, and the air bag 13 is elastically arranged, and an air guide hose 14 is installed through the outer side of the lower end of the air bag 13, and an air outlet 15 is installed through the lower end of the air guide hose 14, and the output end of the air outlet 15 is aligned with the lower end of the high-definition camera 7, and a one-way air inlet 16 is installed through the inner side of the lower end of the air bag 13, and a one-way valve is arranged inside the one-way air inlet 16;

[0034] In the embodiment, a threaded rod 10 capable of adjusting the height of the lifting rod 4 is arranged inside the fixing rod 3. When the height of the lifting rod 4 and the high-definition camera 7 needs to be adjusted, the servo motor 9 is started to control the threaded rod 10 to rotate. When the threaded rod 10 rotates, it drives the lifting rod 4 threadedly connected on its surface.

[0037] In the embodiment, when the staff cannot react due to the induction of the obstacle avoidance sensor 8, the high-definition camera 7 collides with the obstacle. When the high-definition camera 7 is collided, pressure is applied to the junction box 5, and the junction box 5 squeezes the reset spring 17 upward.
