[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-7 , the present invention provides a new technical solution: a dust-proof road security monitoring camera, including an installation box 1, a monitoring camera 13 is fixedly installed inside the installation box 1, the front end of the monitoring camera 13 penetrates through the front surface of the installation box 1, a dust-proof component, the dust-proof component is arranged on the installation box 1, and the dust-proof component includes a circular sleeve 11 and two rectangular protective boxes 7; Among them, the circular sleeve 11 is fixedly connected to the front surface of the installation box 1, the lens of the monitoring camera 13 is located inside the circular sleeve 11, rectangular boxes 10 are fixedly installed on the left and right inner walls inside the circular sleeve 11, and arc-shaped air outlet boxes 12 communicated with their interiors are fixedly connected to the opposite surfaces of the two rectangular boxes 10; Among them, both arc-shaped air outlet boxes 12 are inclined, the arc-shaped air outlet box 12 on the left is used for air outlet, and the arc-shaped air outlet box 12 on the right is used for air intake; Among them, two rectangular protective boxes 7 are respectively fixedly connected to the left and right sides of the installation box 1, and installation grooves 17 communicated with their interiors are opened on the upper surfaces of the two rectangular protective boxes 7.

[0023] Furthermore, protective boxes 5 are fixedly installed on the opposite surfaces of the two rectangular protective boxes 7, and bidirectional threaded rods 21 are rotatably connected to the front and rear inner walls inside the two protective boxes 5; Among them, turbine 19 is fixedly sleeved on the outer walls of the two bidirectional threaded rods 21, and worm 20 is arranged on the opposite surfaces of the two turbines 19.

[0024] Furthermore, the two worms 20 are respectively meshed with the corresponding turbines 19, and the two worms 20 are respectively rotatably connected to the inner walls of the corresponding protective boxes 5; Among them, the upper ends of the two worm gears 20 respectively penetrate through the upper surfaces of the corresponding protective boxes 5 in a rotating manner, and connecting heads are fixedly connected to the upper ends of the two worm gears 20.

[0025] Furthermore, two moving sleeves 22 are threadedly sleeved on the outer walls of the two bidirectional threaded rods 21, and L-shaped moving plates 6 are fixedly connected to the upper surfaces of the two moving sleeves 22; Among them, one ends of the four L-shaped moving plates 6 away from the moving sleeves 22 respectively slide through the outer surfaces of the corresponding protective boxes 5.

[0026] Furthermore, clamping plates 23 are slidably clamped on the inner walls of the four installation grooves 17, rectangular installation grooves 25 are formed in the two clamping plates 23, and filter nets 26 are fixedly installed on the inner walls of the two rectangular installation grooves 25.

[0027] Furthermore, mounting plates 2 are fixedly connected to the upper surfaces of the two clamping plates 23, rectangular plates 4 are fixedly connected to the lower surfaces of the two mounting plates 2, and clamping grooves 24 are formed in the four rectangular plates 4.

[0028] Furthermore, mounting pipes 8 communicated with the interiors thereof are fixedly installed on the front surfaces of the two rectangular protective boxes 7, and an exhaust fan is fixedly installed inside the mounting pipe 8 on the left side; Among them, an intake fan is fixedly installed inside the mounting pipe 8 on the right side; Among them, first air delivery pipes 9 communicated with the interiors thereof are fixedly connected to the front surfaces of the two mounting pipes 8, the two first air delivery pipes 9 are respectively fixedly connected to the corresponding arc-shaped air outlet boxes 12, and the two first air delivery pipes 9 are respectively communicated with the corresponding arc-shaped air outlet boxes 12.

[0032] Further, when using this dust-proof road security monitoring camera, first rotate the worm 20 through the connector. The worm 20 meshes with the turbine 19 to drive the bidirectional threaded rod 21 to rotate.

At the same time, the suction fan in the right installation pipe 8 starts synchronously to generate negative pressure, and sucks the dust and air into the interior of the rectangular protection box 7 on the right through the arc-shaped air outlet box 12 and the first air pipe 9 on the right; Among them, it is discharged after being filtered by another group of filter nets 26 to prevent dust from accumulating on the lens surface; Among them, the ventilation holes 18 of the partition plate 16 ensure the flow of air in the installation box 1, realizing passive heat dissipation while preventing dust, and avoiding the generation of condensed water on the lens due to temperature difference; Among them, when it is necessary to clean the filter net 26, rotate the connector in the reverse direction to make the clamping plate 23 slide out of the installation groove 17, and remove the installation plate 2 to take out the filter net 26 for cleaning. The modular design is convenient for maintenance; Among them, the coordinated operation of the exhaust fan and the suction fan forms a positive pressure air curtain on the lens surface. Combined with the filtering system, it effectively prevents pollutants such as dust and haze from adhering, ensuring that the monitoring picture is clear and stable for a long time; Among them, by setting the dust-proof component, active dust-proof protection of the monitoring camera is realized, adapting to the high-dust and multi-pollution environment in the road security scenario, reducing the manual cleaning frequency, improving the reliability of the equipment. At the same time, the air flow circulation is used to take into account the heat dissipation function, avoiding lens blurring or equipment failure caused by dust accumulation, and ensuring the continuous and effective operation of the monitoring system.
