Description

Technical Field

[0001] This utility model relates to the field of safety protection products, specifically to an electrical safety belt. Background Technology

[0002] In daily operations and emergency repairs in the power industry, workers often face numerous complex and dangerous environments. Typically, workers wear electrical safety belts to reduce the risk of falls. However, traditional electrical safety belts are often made of ordinary synthetic fibers or cotton, which are inexpensive. In situations such as fires caused by electrical equipment malfunctions or high-temperature electric arcs, these safety belts are insufficient for protection. They are highly flammable under high temperatures and burn rapidly. Once ignited, they not only fail to protect workers but may also melt and stick to their skin, exacerbating injuries. Especially when temperatures reach 400 degrees Celsius, the strength of ordinary electrical safety belts rapidly decreases, making them unable to support the weight of a person and leading to a fall. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electrical safety belt with high fire resistance and flame retardancy, which effectively reduces the safety risks of workers in fire environments and provides strong protection for life safety.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An electrical safety belt includes a safety belt body for wearing by a worker; its distinguishing feature is that the electrical safety belt also includes a control box, a microcontroller module, a flame sensor, a temperature sensor, an audible and visual alarm module, and a power supply module; the safety belt body has three layers, wherein the outermost layer is a fire-retardant coating, the middle layer is a blended fiber layer, and the innermost layer is a cushioning layer; the control box is disposed on the surface of the safety belt body, the microcontroller module and the power supply module are disposed inside the control box, multiple flame sensors and temperature sensors are disposed thereon on the outer surface of the safety belt body and electrically connected to the microcontroller module; the audible and visual alarm module is disposed on the surface of the control box and is electrically connected to the microcontroller module; the power supply module is used to provide operating voltage.

[0006] Furthermore, the audible and visual alarm module includes a speaker and a flashing light mounted on the surface of the control box.

[0007] Furthermore, the seat belt body is provided with an adjustment buckle.

[0008] Furthermore, the surface of the seat belt body is provided with reflective marking stickers.

[0009] The beneficial effects of this utility model are:

[0010] The electric safety belt provided by this utility model has a fire-retardant coating on its outermost layer. This coating is ultra-thin, transparent, and has strong adhesion. It does not affect the flexibility and strength of the safety belt, and at the same time, it can further improve the fire-retardant performance of the safety belt. When it encounters a fire source, the coating will rapidly expand to form a dense heat insulation layer, preventing heat from being transferred to the inside of the belt and slowing down the burning speed of the belt. In addition, the surface of the safety belt is also equipped with a flame sensor and a temperature sensor. When the flame sensor detects that the safety belt is being burned by a fire source, and when the temperature sensor detects that the temperature of the safety belt exceeds a set value, the microcontroller module will control the sound and light alarm module to issue an alarm to remind the operator to take appropriate safety measures and replace the safety belt in time, thereby effectively reducing the safety risks of operators in fire environments and providing strong protection for life safety.

[0016] The present invention will now be described in conjunction with the accompanying drawings. The specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Various modifications and improvements to the technical solutions of the present invention made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope of the present invention.

[0017] like Figures 1 to 4 As shown, the power safety belt in this embodiment includes a safety belt body 1 for wearing on the worker, and also includes a control box 2, a microcontroller module 3, a flame sensor 4, a temperature sensor 5, an audible and visual alarm module 6, and a power supply module 7.

[0018] In this embodiment, the safety belt body 1 adopts a five-point safety belt structure, including two shoulder straps, two leg straps, and one waist belt. All parts are tightly connected by metal connectors, which can evenly distribute the impact force generated during a fall, ensuring balanced force distribution on all parts of the worker's body. Furthermore, each part of the belt is equipped with an adjustment buckle 8 for adjusting the tightness.

[0019] In addition, each part of the seat belt body 1 is composed of three layers of material: the outermost layer is a fire-retardant coating 11, the middle layer is a blended fiber layer 12, and the innermost layer is a cushioning layer 13. In this embodiment, the fire-retardant coating 11 is a nano-level fire-retardant coating, which is ultra-thin, transparent, and has strong adhesion. It does not affect the flexibility and strength of the seat belt, while further improving its fire-retardant performance. When exposed to a fire source, the coating rapidly expands to form a dense heat-insulating layer, preventing heat transfer to the interior of the belt and slowing down the burning rate. The coating thickness can be set between 0.1 and 0.3 mm.

[0020] In this embodiment, the blended fiber layer 12 is made of aramid fiber and basalt fiber blended in a certain ratio (e.g., 7:3), and then woven into the main fabric of the seat belt. The seat belt body 1 is made of aramid fiber, which has excellent high temperature resistance and fire retardant properties. It can withstand temperatures of up to 500°C without melting or burning, and it has high strength, with a breaking strength several times that of ordinary fibers, effectively ensuring the safety of the seat belt under stress.

[0021] In this embodiment, the buffer layer 13 is made of silicone rubber sponge. This material has good elasticity and cushioning properties, and can effectively absorb impact force and reduce injury to the human body in the event of a fall. At the same time, silicone rubber sponge has excellent fire-retardant properties, and can play a certain role in heat insulation and protection in a fire.

[0022] The control box 2 is mounted on the surface of the seat belt body 1. The microcontroller module 3 and the power supply module 7 are located inside the control box 2. Multiple flame sensors 4 and temperature sensors 5 are evenly distributed on the outer surface of the seat belt body 1 and are electrically connected to the microcontroller module 3. The audible and visual alarm module 6 is mounted on the surface of the control box 2 and is electrically connected to the microcontroller module 3. The power supply module 7 is used to provide the operating voltage.

[0023] In this embodiment, the microcontroller module 3 uses an STC15W4K56S4 microcontroller as its core, and the power supply module 7 is a battery. The flame sensor 4 in this embodiment is an infrared receiving transistor, a sensor particularly sensitive to flames. It utilizes the infrared sensitivity of infrared light to flames, using a specially designed infrared receiving tube to detect the flame, and then converts the flame brightness into a level signal for the controller to process. In the circuit, multiple flame sensors 4 are represented by Q10, Q11, Q12… When the seatbelt body 1 is ignited by a fire source, the flame sensor 4 conducts and outputs a detection signal to the input terminal of the microcontroller module 3. The temperature sensor 5 in this embodiment uses a DS18B20 temperature sensor to detect the temperature of the seatbelt body 1 and sends the detection signal to the microcontroller module 3. The audible and visual alarm module 6 in this embodiment includes a speaker and a flashing light mounted on the surface of the control box 2. In the circuit, the speaker is represented by SPEEK, and the flashing light is represented by L.

[0024] In addition, reflective markings 9 are provided on the surface of the safety belt body 1. High-brightness reflective markings 9 are provided in prominent positions on the safety belt. These markings can effectively reflect light in low-light environments, improve the visibility of workers, and make it easier for other personnel to spot them in time. At the same time, in dangerous situations such as fires, they can also help rescuers to quickly locate the target.

[0025] In summary, the outermost layer of the electric safety belt of this utility model is a fire-retardant coating 11. This coating is ultra-thin, transparent, and has strong adhesion. It does not affect the flexibility and strength of the safety belt, and at the same time, it can further improve the fire-retardant performance of the safety belt. When it encounters a fire source, the coating will rapidly expand to form a dense heat insulation layer, preventing heat from being transferred to the inside of the belt and slowing down the burning speed of the belt. The second layer is a blended fiber layer 12, which has excellent high temperature resistance and fire-retardant properties. It can withstand temperatures of up to 500°C or higher without melting or burning, and it has high strength. Its breaking strength is several times that of ordinary fibers, which can effectively ensure the safety of the safety belt under stress.

[0026] In addition, a flame sensor 4 and a temperature sensor 5 are also installed on the surface of the safety belt body 1. When the flame sensor 4 detects that the safety belt body 1 is burning by a fire source, it will send a detection signal to the microcontroller module 3. When the temperature sensor 5 detects that the temperature of the safety belt body 1 exceeds the set value (the microcontroller module 3 has a maximum temperature set, such as 400℃), the microcontroller module 3 will control the sound and light alarm module 6 to issue an alarm (the speaker emits a sound and the flashing light flashes) to remind the workers to take appropriate safety measures and replace the safety belt in time, thereby effectively reducing the safety risks of workers in a fire environment and providing strong protection for life safety.
