[0013] The precision positioning power supply intelligent safety helmet of the present invention has the following advantages: A fan is arranged at the position of the buffer sponge pad in the helmet body relative to the first ventilation opening, and a plurality of second ventilation openings are arranged circumferentially on the lower side of the helmet body. When the staff wears this safety helmet to work in a high-temperature environment, the fan is started to draw in the outside air through the first ventilation opening, then blow it towards the staff's head through the fan, and then discharge it through the plurality of second ventilation openings.

The rotation of the rotating shaft is ensured not to rotate through the clamping between the limiting teeth and the clamping teeth, thereby restricting the length of the protective belt and ensuring that the safety helmet will not fall off due to sudden situations such as falling, impact, and bumping when the staff wears this safety helmet, ensuring the safety of the staff. When the staff presses the winding button, the rotating shaft is pushed to slide in the chute through the winding button, so that the clamping teeth are disengaged from the limiting teeth, and the rotating shaft is driven to rotate by the elasticity of the coil spring, winding the protective belt on the rotating shaft, so that the protective belt is tightened and fits the staff's mandible. The staff can freely adjust the length of the protective belt by manual stretching. After releasing the winding button, a plurality of springs push the winding button to reset, driving the rotating shaft to slide in the chute, so that the clamping teeth and the limiting teeth are restored to be clamped, forming a limit on the rotating shaft.

[0024] In order to better understand the purpose, structure and function of the present invention, the present invention of the precision positioning power supply intelligent safety helmet will be further described in detail below with reference to the accompanying drawings.

[0025] As Figures 1-9As shown in the figure, the precision positioning power supply intelligent safety helmet of the present invention includes a helmet body 1; a buffer sponge pad 2 is arranged inside the helmet body 1; a cap band 3 is circumferentially arranged at the lower part of the inner side of the helmet body 1; a headrest 4 is arranged on the upper side of the cap band 3 and extends to the lower part of the buffer sponge pad 2; a plurality of first ventilation openings 5 are arranged on the upper side of the helmet body 1; a fan 6 is arranged at the position of the buffer sponge pad 2 corresponding to the first ventilation openings 5; a plurality of second ventilation openings 7 are arranged on the peripheral part of the lower side of the helmet body 1; a fixed clamping block 8 is arranged on one side of the helmet body 1; a winding clamping block 9 is arranged on the side of the helmet body 1 opposite to the fixed clamping block 8; a protective belt 10 is connected between the fixed clamping block 8 and the winding clamping block 9; a main control unit 11 is arranged between the helmet body 1 and the buffer sponge pad 2; the main control unit 11 is provided with a multi-mode fusion positioning module 12; the main control unit 11 is provided with a communication module 15; the main control unit 11 is provided with a connection module 17; a battery compartment 19 is arranged at the rear part of the helmet body 1; a power supply battery 20 is arranged inside the battery compartment 19; a photographing module 21 is arranged at the front part of the helmet body 1.

[0026] Combined with Figures 1-9 As shown in the figure, when in use, the safety helmet is worn on the head of the staff. During outdoor work, the heat emitted by the staff's head rises and is discharged through the first ventilation openings 5. At the same time, the second ventilation openings 7 introduce external air into the safety helmet, forming a flowing air current to cool the space inside the safety helmet, having a good ventilation and heat dissipation effect. When the outdoor environmental temperature is relatively high, the power supply battery 20 in the battery compartment 19 supplies power to the fan 6, the fan 6 is started, the external air is drawn in through the first ventilation openings 5, then blown towards the staff's head through the fan 6, and then discharged through the plurality of second ventilation openings 7. Blowing air through the fan 6 provides active heat dissipation for the staff's head, can increase the air flow inside the safety helmet, significantly improve the heat dissipation efficiency, reduce the heat stress of the staff, improve the physiological comfort level, and reduce the health hazards of the staff.

[0027] A volatilization cotton 24 is arranged on the upper side of the buffer sponge pad 2 with respect to the fan 6; a volatile liquid tank 25 is arranged at the position of the top of the helmet body 1 corresponding to the volatilization cotton 24; a plurality of wetting strips 35 are arranged on the upper side of the volatilization cotton 24 and connected to the inside of the volatile liquid tank 25. When the external working environment temperature increases and the cooling and heat dissipation effect of the fan 6 decreases, a heat-volatile liquid is added to the volatile liquid tank 25. The volatile liquid is conducted to the volatilization cotton 24 through the wetting strips 35 and blown towards the staff's head through the fan 6. A large amount of heat is absorbed through the evaporation of the liquid, strengthening the cooling effect of the fan 6 blowing air. At the same time, the evaporation of the liquid enhances the subjective sense of coolness of the staff, prolongs the effective working time under high temperature, reduces the risk of heat stroke, and upgrades the health protection.

[0028] On both sides of the rewinding clamping block 9, there are sliding grooves 26 arranged oppositely; a rotating shaft 27 is slidably arranged in the sliding groove 26; a protective belt 10 is wound around the rotating shaft 27; on both sides of the rotating shaft 27 inside the rewinding clamping block 9, there are engaging teeth 28 arranged oppositely; the rewinding clamping block 9 is provided with limiting teeth 29 opposite to the engaging teeth 28; the engaging teeth 28 and the limiting teeth 29 are connected by clamping; on one side of the rewinding clamping block 9, a rewinding button 30 is slidably arranged; the rotating shaft 27 passes through the rewinding button 30 and a torsion spring 31 is connected between the rotating shaft 27 and the rewinding button 30; a plurality of springs 32 are arranged between the rewinding button 30 and the rewinding clamping block 9. The protective belt 10 connected between the fixed clamping block 8 and the rewinding clamping block 9 assists the staff to fix this safety helmet on the head. The engagement between the limiting teeth 29 and the engaging teeth 28 ensures that the rotating shaft 27 will not rotate, thereby restricting the length of the protective belt 10 and ensuring that the safety helmet will not fall off due to sudden situations such as falling, impact, and bumping when the staff wears this safety helmet, ensuring the safety of the staff. When the staff presses the rewinding button 30, the rotating shaft 27 is pushed by the rewinding button 30 to slide in the sliding groove 26, so that the engaging teeth 28 are disengaged from the limiting teeth 29, and the elastic force of the torsion spring 31 drives the rotating shaft 27 to rotate, winding the protective belt 10 around the rotating shaft 27, so that the protective belt 10 is tightened and fits the staff's mandible. And the staff can freely adjust the length of the protective belt 10 by manual stretching. After releasing the rewinding button 30, the plurality of springs 32 push the rewinding button 30 to reset, driving the rotating shaft 27 to slide in the sliding groove 26, so that the engaging teeth 28 and the limiting teeth 29 are restored to be clamped, forming a limit on the rotating shaft 27 and fixing the protective belt 10.

[0029] The connection module 17 includes a Bluetooth module 18. An alarm light 33 is arranged on the helmet body 1; a loudspeaker 34 is arranged on the helmet body 1; the main control unit 11 is connected to and controls the alarm light 33 and the loudspeaker 34. During use, the main control unit 11 is powered by the power supply battery 20 in the battery compartment 19. The connection module 17 and the Bluetooth module 18 are controlled by the main control unit 11. By scanning the Bluetooth beacons deployed in the operation area and combining the RSSI signal strength indication algorithm, accurate indoor positioning accuracy is achieved, making up for the deficiency of inaccurate positioning of the multi-mode fusion positioning module 12 in the occlusion environment and increasing the positioning accuracy effect of this safety helmet. At the same time, when the operator approaches a dangerous area (such as a high-voltage substation, the edge of a deep pit), the Bluetooth beacon is triggered, and the main control unit 11 controls the alarm light 33 and the loudspeaker 34 to issue an audible and visual alarm in time to remind the staff and other workers to evacuate in time.

[0030] The multi-mode fusion positioning module 12 includes a GPS positioning module 13 and a Beidou positioning module 14. The multi-mode fusion positioning module 12 is controlled by the main control unit 11. The GPS positioning module 13 and the Beidou positioning module 14 are used to accurately position this safety helmet. The positioning accuracy is enhanced through the cooperation of multiple satellite systems, reducing the positioning error caused by signal occlusion. At the same time, the positioning accuracies of the GPS positioning module 13 and the Beidou positioning module 14 are compared and complemented to increase the coverage range and stability within the area.

[0031] The communication module 15 includes a multi-frequency communication module 16. By setting one or more of the NANO or SIM card slots and accessing the operator network, it realizes low-latency data synchronization interaction, data transmission, construction guidance, etc. with the cloud management platform. Moreover, it can locate the trajectory of the staff through real-time data and realize the position sharing among the staff, further increasing the positioning accuracy of this safety helmet.

[0032] The photographing module 21 includes an illuminating headlamp 22 and a camera 23. The working scene illumination is optimized by setting up the illuminating lamp to adapt to the construction in low-light environments such as at night, reducing the misoperation caused by unclear vision. At the same time, the light of the illuminating lamp is used to supplement the light for the camera 23 to ensure the clarity of the video captured by the camera 23. The real-time video of the staff is captured and transmitted back by the camera 23 to form a site record to prevent information omission. At the same time, remote collaboration such as remote expert diagnosis and emergency command can be carried out through the captured images of the camera 23 in cooperation with the information transmission of the communication module 15, facilitating the solution of complex problems.
