AI Technical Summary
The support rods of traditional surveillance cameras lack shock absorption and stability functions, resulting in vibration transmission caused by vehicle vibration and wind pressure, causing problems such as loosening and falling off internal parts of the camera, and increasing maintenance costs.
A highway toll station surveillance camera shock-absorbing stabilization support rod including rod body, upper and lower section shock absorber, shock absorber, stabilizer, base and bracket is designed. The shock absorber absorbs vertical vibration through the cylinder and piston, and the stabilizer reduces lateral shaking through the steel rope and the lob.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of monitoring auxiliary equipment, in particular to a shock-absorbing and stabilizing support rod for a monitoring camera at a highway toll station with shock-absorbing and stabilizing functions. Background Art
[0002] Contemporary Chinese highways are developing towards the intelligent direction, and gradually forming the scientific and technological concept of "intelligent highways". The intelligent highway proposes to introduce Internet thinking and technologies to reconstruct and recreate the traditional highway electromechanical system and management services. The initial construction task is to improve the operation management level and travel service quality of highways through information exchange and sharing, data fusion and mining, and realize the informatization and intelligence of services such as provincial highway monitoring management, emergency command, auxiliary decision-making, business handling, and travel guidance. Highways have entered the digital age from electronic informatization, starting with ETC free-flow toll collection, and future highways will continue to evolve towards intelligent highways. Digitalization is the foundation of intelligent highways, mainly focusing on the perception + cognition of the road network. On the basis of perception and cognition, an intelligent road network is gradually built, and finally the mutual trust and coordination of people, vehicles, and roads are realized.
[0003] Monitoring cameras are important equipment for building intelligent highways, used to monitor and collect information on passing vehicles. However, due to the large traffic flow on highways and the long-term dense state, the vibrations generated when vehicles pass through the speed bumps at the toll station entrances and exits will be transmitted to the monitoring cameras set beside. At the same time, when vehicles are driving, wind pressure will also be generated. Although the impact of each time is very small, due to the large traffic flow, the cumulative vibration impact over a long time cannot be ignored. In daily maintenance, it is often found that the internal parts of the monitoring cameras are loose, fall off, etc., causing damage to the monitoring cameras and increasing the equipment maintenance cost.
[0004] Currently, the support rods of traditional monitoring cameras are very single in function and design, and can only play a role in fixing and supporting. They lack effective shock-absorbing and stabilizing function designs and cannot prevent the vibrations generated when vehicles pass through the speed bumps at the toll station entrances and exits from being transmitted to the monitoring cameras set beside, thus causing damage to the monitoring cameras. Summary of the Invention
[0005] The problem to be solved by the utility model is the problem that the traditional support rod of the monitoring camera does not have shock-absorbing and stabilizing functions in the design, and provides a shock-absorbing and stabilizing support rod for a monitoring camera at a highway toll station with shock-absorbing and stabilizing functions.
[0006] The shock-absorbing and stabilizing support rod for the monitoring camera at the highway toll station of the present utility model is characterized in that the support rod comprises a rod body, an upper shock-absorbing rod, a lower shock-absorbing rod, a shock absorber, a stabilizer, a base and a bracket. The rod body is a hollow cylinder and is placed on the base. The shock-absorbing rod is arranged inside the rod body, and the outer wall of the shock-absorbing rod contacts the inner wall of the rod body. The shock-absorbing rod is divided into an upper section and a lower section, and the two sections are connected by a shock absorber. The bracket is fixed at the top of the shock-absorbing rod, and the bottom of the shock-absorbing rod is fixed on the base. There is a hollow section inside the lower section of the shock-absorbing rod, and a stabilizer is arranged in the hollow section. Among them:
[0007] The shock absorber includes an oil cylinder and a piston. The piston is arranged inside the oil cylinder. The disc at the bottom of the piston divides the oil cylinder into an upper cavity and a lower cavity. The upper cavity is filled with air, and the lower cavity is filled with hydraulic oil.
[0008] The stabilizer includes a steel wire rope and a hanging ball. The top of the steel wire rope is fixed at the top of the hollow section, and the hanging ball is suspended at the bottom end of the steel wire rope.
[0009] First, fix the base on the platforms on both sides of the lane through ground nails, install the support rod on the base, and fix the monitoring camera on the bracket. When the vehicle passes and causes vertical vibration due to rolling on the road surface or horizontal sway due to wind pressure, the vertical vibration is transmitted to the shock absorber. The piston of the shock absorber slides up and down in the oil cylinder, transmits the vibration force to the oil cylinder, and absorbs the vertical external force through the oil cylinder. When sliding upward, the air in the upper cavity above the disc of the piston is compressed, and at the same time, the hydraulic oil in the lower cavity is pulled. Through the combined action of air and hydraulic oil, the movement of the piston rod is reduced, and at the same time, the piston rod is reset. When sliding downward, the hydraulic oil is compressed and the air is pulled. When horizontal sway occurs due to wind pressure, the swing of the hanging ball reduces the swing of the support rod and the sway of the base, effectively improving the service life of the support rod.
[0010] The shock-absorbing and stabilizing support rod for the monitoring camera at the highway toll station of the present utility model has a reasonable structure, scientific design and convenient use. The shock absorber and stabilizer are arranged inside the support rod. The vertical vibration is reduced through the shock absorber, and the horizontal sway is reduced through the stabilizer, greatly improving the service life of the support rod and at the same time providing a more stable working environment for the monitoring camera.

[0016] First, fix the base on the platforms on both sides of the lane through ground nails, install the support rod on the base, and fix the monitoring camera on the bracket; when the vehicle passes over the road surface and causes vertical vibrations or lateral sway due to wind pressure, the vertical vibrations are transmitted to the shock absorber. The piston of the shock absorber slides up and down in the oil cylinder, transmitting the vibration force to the oil cylinder. The oil cylinder absorbs the vertical external force. When sliding upward, the air in the upper cavity above the disc of the piston is compressed, and at the same time, the hydraulic oil in the lower cavity is pulled. Through the combined action of air and hydraulic oil, the movement of the piston rod is reduced, and at the same time, the piston rod is reset; when sliding downward, the hydraulic oil is compressed and the air is pulled; when there is lateral sway due to wind pressure, the swinging of the hanging ball reduces the sway of the support rod and the sway of the base, effectively improving the service life of the support rod.
