Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gratings, in particular to an infrared grating radiation protection device. Background Art
[0002] When the scale is in use, light barriers are set up on both sides to automatically detect whether the vehicle has been weighed through the working principle of infrared radiation. However, the existing light barrier installation method is directly exposed to the outside world and is easily damaged by external forces.
[0003] A Chinese patent discloses a safety grating protection mechanism (authorization announcement number CN220853861U). This patented technology uses a support module to wrap the mounting module, so that the detection grating installed on the mounting rail is wrapped by the column. At the same time, the detection grating is protected by the protection module. The support module and the protection module work together to effectively reduce the possibility of external forces impacting the detection grating and reduce the possibility of damage to the monitoring grating.
[0004] However, after long-term use, dust easily accumulates on the surface of the protective plate of the grating, which can easily affect the transmission and reception of light. A Chinese patent discloses a diffuse reflection safety grating (authorization announcement number 2178434555U). This patented technology solves the problem of dust accumulation on the surface of existing diffuse reflection safety gratings by providing a dust cleaning structure. The dust cleaning structure is provided with a high-pressure air pipe and a nozzle. The high-pressure air pipe is used to transport gas and cooperates with the nozzle to blow dust from the grating surface, avoiding the impact of long-term dust accumulation on the grating and ensuring the safe and normal operation of the grating.
[0005] However, it has certain disadvantages: its cleaning structure sprays air from top to bottom, and the wind force gradually decreases from top to bottom, so it can only clean a small area on the upper end of the high-transmittance glass. The lower part of the high-transmittance glass cannot be effectively exposed to the airflow, and thus cannot be fully cleaned. Utility Model Content

Two bumpers 9 are installed on the left and right sides of the column 7, and support rods 10 are installed between the column 7 and the left and right bumpers 9 and between the front and rear bumpers 9.

[0028] The concave base 3 is a solid metal sphere with a spherical lower end and a flat upper end. The counterweight 5 is sufficiently heavy. The inner surface of the concave base 3 movably fits the outer surface of the hemispherical base 4. The concave base 3, the hemispherical base 4, and the counterweight 5 form a structure based on the principle of a tumbler. Therefore, when the protective cover 1 is hit, it will tilt and then reset, thereby cushioning the protective cover 1 and preventing it from being directly deformed by the collision.
