[0002] With the rapid development of infrastructure construction in my country, the number of highway construction projects is increasing, and the importance of construction site safety management is becoming increasingly prominent. Ensuring the safety of life and property of construction site personnel has become an urgent problem to be solved. Traditional safety management methods mainly rely on manual inspections and simple video surveillance. These methods have shortcomings such as low efficiency and limited coverage, and are difficult to adapt to the needs of modern construction safety management. Therefore, the development of an intelligent early warning device that can adapt to complex construction environments and achieve accurate early warning is of great significance to improving the level of construction safety management.

[0003] At present, there are two common methods for construction site safety management. The first is the traditional manual inspection, which is to arrange special safety officers to patrol the construction site regularly. This method is costly and prone to omissions, and it is difficult to achieve full coverage and real-time monitoring. The second is a camera-based video surveillance system, which captures the on-site situation through cameras installed at different angles, and then the background staff monitors the screen for abnormalities.

[0004] However, the camera-based video surveillance system has some limitations. For example, in order to obtain a better field of view, the camera is usually installed in the open air at a high place at the intersection. This makes it difficult to clean the camera when it is blocked by foreign objects such as dust in the air, affecting the camera's clarity and reducing safety. Summary of the invention

A cooling fan is fixedly connected to the inside of the air outlet, and a plurality of cooling fins are symmetrically and evenly fixedly connected to one end of the camera host. The cooling fins are installed inside the air inlet, and an air drying component is installed inside the protective shell.

[0015] By adopting the above technical solution, by setting up the air drying component for use with the heat sink fins and the heat sink fan, it is convenient to start the heat sink fan to draw air through the air inlet and the air outlet, and cooperate with the heat sink fins to complete the contact heat exchange with the camera host, and at the same time guide the air to achieve air drying of the water-absorbing sponge, thereby facilitating the reduction of the operating temperature of the camera host and maintaining the shooting stability of the camera host.

[0020] A highway construction intelligent early warning method, the method steps are as follows: S1: First, the camera host is connected to the early warning terminal, and the monitoring information is transmitted to the early warning terminal for analysis in real time, and the images are transmitted to the construction site in real time; S2: When the camera host detects that the image acquisition clarity decreases, the system automatically triggers the cleaning mechanism. At this time, the drive motor is started to drive the positioning roller to drive the drive gear to engage with the drive chain, and the high-definition transparent protective film is circulated with four support rollers as fulcrums, so that the high-definition transparent protective film in front of the image acquisition end of the camera host moves around the support roller to the bottom of the positioning roller inside the cleaning tank, while maintaining the cleanliness of one end of the high-definition transparent protective film in front of the image acquisition end of the camera host; S3: Start the solenoid valve to evenly spray the cleaning liquid inside the material distribution pipe onto the dust-contaminated surface of the high-definition transparent protective film through the nozzle, so as to reduce the adhesion of foreign matter such as dust on the surface of the high-definition transparent protective film; S4: The positioning roller is driven to drive the cross-interference block to rotate synchronously.

The air is first filtered and intercepted by the annular filter to intercept foreign matter such as dust in the air. When the air passes through the air inlet and is discharged through the air outlet, it contacts and exchanges heat with the camera host through the surface of multiple cooling fins, thereby reducing the operating temperature of the camera host.

[0021] In summary, the present application includes at least one of the following beneficial effects: 1. By setting up the coordinated use of the transmission component and the cleaning component, the driving motor can be started to drive the positioning roller to drive the driving gear to engage with the driving chain, thereby driving the high-definition transparent protective film to circulate with four supporting rollers as fulcrums and contact the outside world. One end of the contaminated high-definition transparent protective film bypasses the positioning roller and moves to the inside of the cleaning tank, while one end of the uncontaminated high-definition transparent protective film bypasses the supporting roller and moves to the front of the camera host image acquisition end of the camera host, thereby maintaining the cleanliness of one end of the high-definition transparent protective film in front of the camera host image acquisition end, making the image acquisition of the camera host clearer and improving the safety of the device.

[0022] 2. By setting the reciprocating slide rod and the reciprocating slider, the reciprocating spring and the cross-interference block, the positioning roller is driven to rotate and the cross-interference block is driven to form a conflict with the reciprocating slider. The elastic characteristics of the reciprocating spring are utilized to rebound after being subjected to force to drive the sponge slider to move back and forth along the length direction of the reciprocating slide groove. At the same time, the sponge slider is used in conjunction with the cleaning component to quickly frictionally clean the high-definition transparent protective film that bypasses one end of the positioning roller, so as to achieve rapid cleaning of one end of the high-definition transparent protective film, thereby improving the practicability of the device.

[0023] 3. By setting up the coordinated use of the air guide plate and the air permeable slot, it is convenient to use the air guide plate to guide the air passing through the air inlet and the air outlet, and blow it to one end of the water-absorbing sponge through the air permeable slot, thereby taking away the moisture inside the water-absorbing sponge, so as to maintain the internal dryness of the water-absorbing sponge, improve the water absorption effect of the water-absorbing sponge, and further improve the surface cleaning effect of the device on the high-definition transparent protective film.
