[0002] The visual early warning smart safety helmet is a new type of construction site safety equipment. Its computer vision-based detection algorithm analyzes real-time video streams, which can overcome the physical limitations of manual supervision, achieve 24 / 7 full-scene coverage, and improve the safety factor of construction site operations.

[0003] Most of the visual warning smart safety helmets currently on the market are similar in overall structure, with the helmet as the main body, a camera mounted on the front, and a speaker for broadcasting. However, they have some functional shortcomings in actual use. For example, the camera lens tilt angle is fixed, and the shooting angle is generally a level view. When people of different heights wear them, the images captured vary greatly. Furthermore, the image capture needs are different in different working environments. For example, when working underground, the blind spot above the head needs to be paid special attention to, while construction site work focuses more on the situation in front. They cannot be flexibly adjusted as needed and do not have the function of easily adjusting the camera tilt angle.

[0004] Now, a new type of visual warning smart safety helmet is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a visual warning smart safety helmet to solve the problem mentioned in the background art that it does not have the function of easily adjusting the camera pitch angle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a visual warning smart safety helmet, comprising a helmet body, a brim fixedly connected to the front end of the helmet body, a main shell fixedly connected to the middle position of the top of the brim, a concave shell fixedly connected to the middle position of the front end of the main shell, a camera module disposed inside the concave shell, speakers respectively installed on both sides of the front end of the main shell, three sets of control buttons disposed on the top of the main shell, a control circuit board fixedly connected to the bottom of the interior of the main shell, a left shell fixedly connected to the left side of the main shell, a right shell fixedly connected to the right side of the main shell, battery compartments fixedly connected to the left and right sides of the helmet body, a charging port disposed on the top of the battery compartment, and an adjustable component for camera angle disposed inside the concave shell.

[0007] The adjustment assembly includes two sets of fixed tube seats, which are respectively fixedly connected to both sides inside the concave shell.

Two sets of camera wiring are respectively provided on both sides of the camera module. Limiting rings are fixedly connected to the outside of the extension tubes.

[0008] As a further technical solution of this utility model, the extension tube passes through the interior of the fixed tube seat and the damping rubber ring and extends into the interior of the main housing, and the inner diameter of the damping rubber ring and the outer diameter of the extension tube are matched.

[0009] As a further technical solution of this utility model, the extension tube can rotate along the inside of the damping rubber ring, and the damping rubber ring is elastic.

[0010] As a further technical solution of this utility model, the fixed tube base is symmetrically distributed about the vertical center line of the camera module, and the camera wiring and control circuit board are electrically connected.

[0011] As a further technical solution of this utility model, a sample cover is fixedly connected to the top of the left side shell, and an infrared temperature sensor is installed at the bottom of the inside of the left side shell. The cap and the sample cover are made of the same material, and the speaker, the infrared temperature sensor, and the control circuit board are electrically connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the visual warning smart safety helmet not only realizes the function of easily adjusting the camera tilt angle, but also realizes the function of temperature monitoring and the function of gas monitoring in the work area;

[0014] (1) By setting up a concave shell, camera module, extension tube, camera wiring, fixed tube seat, damping rubber ring and limit ring, when in use, the helmet body serves as the main body of the safety helmet and is worn on the worker's head. The camera module collects image information of the work area in real time. When violations or safety hazards are discovered, the speaker broadcasts voice reminders. According to the needs of the work scene and the height of the personnel, the pitch angle of the camera module can be adjusted. By bending the camera module, the camera module together with the extension tubes on both sides can rotate along the inside of the fixed tube seat, and the pitch angle can be changed. The damping rubber ring increases the friction between the extension tube and the fixed tube seat, so that it can maintain a relatively stable state after adjustment, thus realizing the function of easy adjustment of the camera pitch angle.

[0015] (2) By setting up a left side shell, a sample cover and an infrared temperature sensor, the infrared temperature sensor monitors the temperature of the sample cover in real time when working outdoors. When the temperature exceeds the preset threshold, it indicates that the outside weather is hot and it is not suitable to continue working. The speaker broadcasts a voice reminder to avoid safety accidents and realizes the function of temperature monitoring.

[0016] (3) By setting up a right side shell, air inlet, gas sensor and negative pressure fan, when working underground, the negative pressure fan at the top of the right side shell will exhaust the air by suction, and the outside air will flow into the right side shell along the air inlet. The gas sensor can detect the air composition in real time. If gas leakage is found, the speaker will broadcast a voice reminder to avoid causing a safety accident, thus realizing the function of gas monitoring in the work area. Attached Figure Description

Limiting rings 10 are fixedly connected to the outside of the extension tubes 6.

[0025] The extension tube 6 passes through the interior of the fixed tube seat 8 and the damping ring 9 and extends into the interior of the main housing 3. The inner diameter of the damping ring 9 is matched with the outer diameter of the extension tube 6. The extension tube 6 can rotate along the interior of the damping ring 9. The damping ring 9 is elastic. The fixed tube seat 8 is symmetrically distributed about the vertical center line of the camera module 5. The camera wiring 7 and the control circuit board 16 are electrically connected to facilitate the adjustment of the camera's pitch angle.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, by bending the camera module 5, the camera module 5, together with the extension tubes 6 on both sides, can rotate along the inside of the fixed tube seat 8, and the pitch angle can be changed. The damping rubber ring 9 increases the friction between the extension tube 6 and the fixed tube seat 8, so that it can maintain a relatively stable state after adjustment.

[0027] A sample cover 14 is fixedly connected to the top of the left shell 13, and an infrared temperature sensor 15 is installed at the bottom inside the left shell 13. The cap 1 and the sample cover 14 are made of the same material. The speaker 11, the infrared temperature sensor 15, and the control circuit board 16 are electrically connected, which can monitor the temperature of the working area in real time.

[0028] Specifically, such as Figure 1 and Figure 2As shown, the infrared temperature sensor 15 monitors the temperature of the sample cover 14 in real time.

The speaker 11, the control circuit board 16, and the gas sensor 19 are electrically connected. This technology is existing technology and will not be described in detail.

[0031] Working Principle: In use, the helmet body 1 serves as the main body of the safety helmet and is worn on the worker's head. The camera module 5 collects real-time image information of the work area. When violations or safety hazards are detected, the speaker 11 broadcasts a voice reminder. The tilt angle of the camera module 5 can be adjusted according to the needs of the work scene and the height of the worker. By turning the camera module 5, the camera module 5, together with the extension tubes 6 on both sides, can rotate along the inside of the fixed tube seat 8, and the tilt angle can be changed. The damping rubber ring 9 increases the friction between the extension tube 6 and the fixed tube seat 8, so that it can maintain a relatively stable state after adjustment. When working outdoors, the infrared temperature sensor 15 monitors the temperature of the sample cover 14 in real time. When the temperature exceeds the preset threshold, it indicates that the outside weather is hot and it is not suitable to continue working. The speaker 11 broadcasts a voice reminder to avoid safety accidents. During underground operations, the negative pressure fan 20 at the top of the right shell 17 draws out air, and the outside air flows into the right shell 17 through the air inlet 18. The gas sensor 19 can detect the air composition in real time. If a gas leak is detected, the speaker 11 will broadcast a voice reminder to avoid causing a safety accident.
