Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, specifically to a proximity alarm helmet. Background Technology

[0002] With the rapid development of the power industry and the field of high-altitude operations, workers often need to work in complex environments such as high temperature and high voltage, which places higher demands on the performance of safety protection equipment. While traditional safety helmets provide basic head protection, they still have significant shortcomings in practical applications:

[0003] Firstly, the heat dissipation performance is insufficient. Traditional helmets have simple or no ventilation structure, which leads to the accumulation of internal heat when worn for a long time, easily causing the user's head to feel stuffy and seriously affecting work comfort and efficiency.

[0004] Secondly, there is a lack of proactive safety warning functions. In high-voltage working environments, there is a risk of electric shock when personnel approach live equipment. However, existing helmets generally do not integrate proximity warning devices, making it impossible to detect and warn of surrounding voltage hazards in advance, which greatly increases the risk of operational safety. At the same time, the connection between the EPS cushioning pad and the helmet body in existing technologies is mostly fixed, which is inconvenient to disassemble and install, and not conducive to cleaning, maintenance or personalized adjustments.

[0005] Therefore, it is necessary to develop a safety helmet that combines efficient heat dissipation, multi-level proximity warning, and adjustable shock absorption structure to solve the problems of insufficient safety, comfort, and functionality in existing technologies and meet the actual needs in complex working environments. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the shortcomings of the existing technology, this utility model provides a proximity alarm helmet, which solves the technical problems mentioned in the background.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a proximity alarm helmet, comprising a helmet body, an installation groove provided on the front side of the helmet body, and a proximity warning device installed in the installation groove; an EPS cushioning pad provided on the inner side of the helmet body, and a skin-friendly cotton provided on the upper side of the EPS cushioning pad, and the skin-friendly cotton is attached to the Velcro of the inner wall of the helmet body; multiple heat dissipation grooves running from front to back are provided in the EPS cushioning pad, and multiple air guide holes are provided on the bottom side of the heat dissipation grooves; a heat dissipation system is provided on the rear side of the EPS cushioning pad.

[0010] Preferably, the warning voltage of the proximity warning device is adjustable to three levels: 220V, 10KV, and 35KV, and the proximity warning device is equipped with a main switch.

[0011] Preferably, the warning distances of the proximity warning device at the specified levels are 0.45-0.75 meters for V warning, 0.9-1.5 meters for KV warning, and 1.5-2.5 meters for KV warning.

[0012] Preferably, the loudspeaker alarm sound pressure level of the proximity warning device is not less than 70 dB at a distance of meters.

[0013] Preferably, the EPS cushioning pads are distributed on the top and sides inside the helmet body, and the EPS cushioning pads are made of EPS material.

[0014] Preferably, the heat dissipation system includes a small fan and a magnetic base. The small fan is located on the rear side of the EPS cushioning pad and is attached to the magnetic base, which is installed on the rear side of the helmet body.

[0015] Preferably, the rear ends of the heat dissipation slots in the EPS buffer pad are connected together, and the air outlet of the small fan is provided with an air guide pipe connected to the rear ends of the multiple heat dissipation slots.

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This type of proximity alarm helmet has an EPS cushioning pad inside. By opening a mounting slot on the rear side of the helmet and installing an adjustable warning voltage proximity alarm, it achieves real-time monitoring and warning of the surrounding electric field strength. The proximity alarm is close to the ears to ensure the coverage of the speaker alarm sound. The proximity alarm has accurate warning distances at three specified levels: 0.45-0.75 meters for 220V, 0.9-1.5 meters for 10KV, and 1.5-2.5 meters for 35KV, ensuring the accuracy and reliability of the warning.

[0019] 2. This type of proximity alarm helmet, by having multiple heat dissipation grooves and air guide holes on the EPS buffer pad, can form an effective air circulation in conjunction with the heat dissipation system, thereby improving the heat dissipation efficiency inside the helmet. At the same time, the EPS material of the EPS buffer pad has good elasticity, which reduces the impact force on the head after the helmet is subjected to external force, and can also improve the wearing comfort of the helmet.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] like Figure 1 , 2As shown, this utility model provides a technical solution: a proximity alarm helmet, including a helmet body 1. A knob locking system is provided on the rear side of the helmet body 1. When the knob is rotated, it drives internal gears or webbing to tighten / loosen, realizing the adjustment of the helmet's tightness to ensure a proper fit to the head. A mounting groove 2 is provided on the front side of the helmet body 1, and a proximity warning device 3 is installed in the mounting groove 2. The proximity warning device 3 has three adjustable warning voltage levels: 220V, 10KV, and 35KV. The proximity warning device 3 is equipped with a master switch. The proximity warning device 3 is activated at the specified warning level. The warning distances are 0.45-0.75 meters for 220V, 0.9-1.5 meters for 10KV, and 1.5-2.5 meters for 35KV. The speaker alarm sound pressure level of the proximity warning device 3 is not less than 70dB at 1 meter. Depending on the working environment, the warning voltage can be selected from 220V, 10KV, or 35KV via the switch on the proximity warning device 3. After the helmet body 1 is worn, the proximity warning device 3 will be in working condition, operating within a range of 0.45-0.75 meters under 220V voltage. When the helmet is within 0.9-1.5 meters of the helmet at 10KV voltage, and within 1.5-2.5 meters of the helmet at 35KV voltage, the speaker of the proximity warning device 3 will trigger an alarm sound to alert the personnel. An EPS buffer pad 4 is installed inside the helmet body 1. The EPS buffer pad 4 consists of three longitudinally distributed pads, located at the top and sides of the helmet body 1. The EPS buffer pad 4 is made of EPS material, and a slot is provided on the front side of the EPS buffer pad 4 corresponding to the proximity warning device 3 to prevent exposure to the electric shock. The warning device 3 provides a shielding and coverage. The EPS material of the EPS cushioning pad 4 has good elasticity, which reduces the impact force on the head after the helmet is subjected to external force and can improve the wearing comfort of the helmet. The upper side of the EPS cushioning pad 4 is provided with skin-friendly cotton 5, and the skin-friendly cotton 5 is attached to the rough surface of the Velcro 6 on the inner wall of the helmet body 1. The adhesive sheet made of skin-friendly cotton 5 has sufficiently fluffy fibers on its surface, which can be attached to the "hook surface" on the Velcro 6. The EPS cushioning pad 4 has multiple heat dissipation grooves 7 running from front to back, and multiple air guide holes 8 are opened on the bottom side of the heat dissipation grooves 7, which can be used for the heat dissipation of the helmet.

[0029] Example 2

[0030] Based on Embodiment 1, another technical solution is also provided, such as... Figure 3 , 4As shown in Figure 5, a heat dissipation system is provided on the rear side of the EPS cushioning pad 4. The heat dissipation system includes a small fan 9 and a magnetic base 10. The small fan 9 is located on the rear side of the EPS cushioning pad 4 and is attached to the magnetic base 10 for easy removal. The magnetic base 10 is installed on the rear side of the helmet body 1. A button switch is provided on the outside of the shell of the small fan 9, and a battery is integrated inside the shell of the small fan 9. The rear ends of the heat dissipation slots 7 in the three EPS cushioning pads 4 are connected together, and the air outlet of the small fan 9 is provided with an air guide pipe connected to the rear ends of multiple heat dissipation slots 7. By using the button switch on the outside of the shell of the small fan 9, the small fan 9 is turned on. The air outlet of the small fan 9 is connected to multiple heat dissipation slots 7 through the air guide pipe, so that the airflow can be evenly distributed to the entire interior of the helmet through multiple heat dissipation slots 7. The airflow comes into contact with the head through the air guide hole 8, so that the outer and inner sides of the helmet body 1 form an effective air circulation, improve the heat dissipation effect inside the helmet body 1, and thus effectively reduce the temperature of the wearer's head.

[0031] The operational steps for this application are as follows:

[0032] Depending on the working environment, by using the switch on the proximity warning device 3 to select one of the warning voltages of 220V, 10KV, or 35KV, and then wearing the helmet body 1 on the head, the proximity warning device 3 will be in working condition. When the distance is within 0.45-0.75 meters under 220V voltage, within 0.9-1.5 meters under 10KV voltage, and within 1.5-2.5 meters under 35KV voltage, the speaker of the proximity warning device 3 will trigger an alarm sound to warn the staff.

[0033] The small fan 9 is turned on by the button switch on the outside of the small fan 9 housing. The air outlet of the small fan 9 is connected to multiple heat dissipation slots 7 through the air guide tube, so that the airflow can be evenly distributed to the entire interior of the helmet through the multiple heat dissipation slots 7. The airflow comes into contact with the head through the air guide hole 8, so that the outer and inner sides of the helmet body 1 form an effective air circulation, improve the heat dissipation effect inside the helmet body 1, and thus effectively reduce the temperature of the wearer's head.
