Description

Technical Field

[0001] This utility model relates to the field of rescue and protection technology, and in particular to a protective device for mine rescue. Background Technology

[0002] Mining operations are fraught with risks, potentially leading to various accidents that pose serious threats to miners' lives, company property, and social stability. When a mine accident occurs, miners may be trapped underground, facing dangers such as oxygen deprivation, exposure to toxic gases, water inrush, and roof collapses. Therefore, mine rescue teams are needed to quickly rescue trapped personnel, provide them with necessary medical assistance, and minimize casualties. Due to the presence of multiple hazardous factors at mine accident sites, such as toxic gases, roof collapses, explosive shocks, high temperatures, and dust, protective equipment is essential to ensure the safety and health of rescue personnel, enabling them to complete rescue missions in harsh environments.

[0003] However, while existing protective devices protect the eyes and face from injury, the protective lenses are prone to fogging due to temperature changes, affecting vision. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a protective device for mine rescue, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a protective device for mine rescue, including a protective goggle worn on the head of a rescuer. A protective lens for protecting the goggles is fixedly installed inside the goggle. Temperature sensors are provided on both the inner and outer sides of the protective lens. The temperature sensors are signal-connected to a micro-control unit for automated control. The micro-control unit is signal-connected to a closed partition for isolation. A purification filter cloth for filtering harmful gases is provided on one side of the closed partition. A guide vane for guiding airflow to the protective lens is fixedly installed at one end of the purification filter cloth. Fastening plates are fixedly installed at both ends of the guide vane for securing it. A sealing gasket for sealing is fixedly installed at one end of the closed partition. A gas chamber for containing gas is provided on one side of the sealing gasket. One end of the gas chamber is connected to a gas guide groove for guiding gas flow.

[0006] Preferably, one of the above embodiments is that a tightening strap made of elastic material is provided in the middle of one end of the protective goggles, a frame for fixing the protective lens is provided inside the protective goggles, the temperature sensor is fixedly installed inside the protective goggles, and a vent hole penetrating the protective goggles is provided on the inner side of the protective lens.

[0007] The above technical solution is adopted: the elastic band in the middle of one end of the protective goggles can fit tightly to the rescuer's head, ensuring that the protective goggles are worn securely and will not easily shift in complex rescue environments. The internal frame provides stable support for the protective lenses, making them firmly installed. The ventilation holes on the inside of the protective lenses, together with the overall structure, ensure air circulation inside the protective goggles, improve wearing comfort, and lay the foundation for subsequent air exchange and anti-fog functions.

[0008] Preferably, in any of the above embodiments, the enclosed partition includes an electrically operated telescopic rod connected to a micro control unit and a movable isolation plate. The electrically operated telescopic rod is fixedly installed inside the protective goggles, and one end of the electrically operated telescopic rod is fixedly installed with an isolation plate that moves inside the protective goggles.

[0009] The above technical solution involves an electrically operated telescopic rod controlled by a microcontroller unit installed inside the protective goggles. When a temperature sensor detects an excessive temperature difference between the inside and outside of the protective lens, the microcontroller unit controls the telescopic rod to extend or retract, causing the isolation plate to move within the goggles. By adjusting the position of the isolation plate, airflow between the inside and outside of the goggles can be controlled. When necessary, the isolation plate can be released to allow purified air from outside to enter, balancing the temperature and preventing fogging of the lenses.

[0010] Preferably, in any of the above embodiments, the air guide plate is inserted into the interior of the protective goggles, the interior of the air guide plate has a plurality of air guide holes for gas conduction, the purification filter cloth is located at the top of the air guide holes, the purification filter cloth is located between the isolation plate and the air guide plate, and the air guide holes and the ventilation holes are connected.

[0011] The above technical solution is adopted: the purification filter cloth is located at the top of the air vent and between the isolation plate and the guide plate, which can effectively filter the incoming harmful gases and ensure the breathing safety of rescuers. The air vent is connected to the ventilation hole, so that the purified air can smoothly reach all parts of the protective goggles and achieve effective air circulation. At the same time, it can also blow a certain amount of airflow on the protective lens to reduce the possibility of fogging.

[0012] Preferably, in any of the above embodiments, the fastening piece is made of an elastic metal material and is snapped into the interior of the protective goggles.

[0013] The above technical solution allows the fastening plate to firmly fix the guide plate, ensuring that it will not shake or fall off during use. Moreover, the properties of the elastic metal material give the fastening plate a certain degree of flexibility, making it easy to install and remove the guide plate. It can also adapt to the slight deformation of the protective goggles under different usage conditions and maintain a good fastening effect.

[0014] Preferably, in any of the above embodiments, the sealing gasket is larger than the size of the isolation sheet, and the sealing gasket is located inside the protective goggles.

[0015] The above technical solution is adopted: the sealing gasket is larger than the isolation plate and is located inside the protective goggles. When the isolation plate of the sealing partition moves, the sealing gasket moves with it. This not only enhances the sealing of the inside of the protective goggles and prevents harmful gases from leaking in, but also adjusts the space of the air chamber during the movement. The air is compressed in the air chamber to form an airflow, which blows air onto the inside of the protective lens, further playing the role of anti-fogging and protection.

[0016] Preferably, in any of the above embodiments, the air cavity and the air guide groove are formed inside the protective goggles, the air guide groove and the air guide hole are connected, and the air guide groove is located below the purification filter cloth.

[0017] The above technical solution is adopted: when the sealing gasket moves and squeezes the air chamber, the gas enters the air guide hole through the air guide groove, forming a local rapid airflow. On the one hand, it can blow air to protect the protective lens, and on the other hand, it can help accelerate the air circulation inside the protective goggles, better realize the functions of heat dissipation, ventilation and anti-fogging, and improve the overall performance of the protective device.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. Temperature sensors are installed on both the inner and outer sides of the protective lens to detect the temperature in real time. Based on the temperature data, the temperature difference between the inside and outside of the protective lens is determined. The movement of the sealing partition is controlled according to the temperature difference. When the temperature difference is high, the isolation between the inside and outside of the protective goggles can be released, allowing the air outside the protective goggles to be purified by the filter cloth and then interact with the air inside the protective goggles. This dissipates heat and ventilates the inside of the protective goggles, reduces the temperature difference between the inside and outside of the protective goggles, prevents the protective lens from fogging, and ensures the safety and stability of the protective device.

[0020] 2. An air chamber and air guide groove are opened inside the protective goggles. During the movement of the sealing plate, the sealing gasket will move and shift. By adjusting the internal space of the air chamber by the displacement of the sealing gasket, a certain amount of gas can be compressed, forming a local rapid airflow inside the protective goggles. This is beneficial for blowing air onto the inside of the protective lens and providing a certain degree of protection for the lens.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0030] like Figure 1-5 As shown in the figure, a protective device for mine rescue according to an embodiment of the present invention includes a protective goggle 1 worn on the head of a rescuer.

[0032] The above technical solution is adopted: the elastic band 12 in the middle of one end of the protective goggles 1 can fit tightly to the head of the rescuer, ensuring that the protective goggles are worn securely and will not easily shift in complex rescue environments. The internal frame provides stable support for the protective lens 2, making it securely installed. The ventilation holes 13 on the inside of the protective lens 2, together with the overall structure, ensure air circulation inside the protective goggles, improve wearing comfort, and lay the foundation for subsequent air exchange and anti-fog functions.

[0033] Preferably, in any of the above embodiments, the enclosed partition 4 includes an electric telescopic rod 41 connected to a micro control unit and an movable isolation plate 42. The electric telescopic rod 41 is fixedly installed inside the protective goggles 1, and one end of the electric telescopic rod 41 is fixedly installed with the isolation plate 42 that moves inside the protective goggles 1.

[0034] The above technical solution employs a microcontroller-controlled electric telescopic rod 41, installed inside the protective goggles 1. When the temperature sensor 3 detects an excessive temperature difference between the inside and outside of the protective lens 2, the microcontroller-controlled electric telescopic rod 41 extends or retracts, causing the isolation plate 42 to move within the protective goggles 1. By adjusting the position of the isolation plate 42, the airflow between the inside and outside of the protective goggles 1 is controlled. When necessary, the isolation is released, allowing purified air from the outside to enter, balancing the temperature and preventing the lens from fogging.

[0035] Preferably, in any of the above schemes, the guide plate 6 is inserted into the interior of the protective goggles 1, and the interior of the guide plate 6 has a plurality of air guide holes 11 for conducting gas. The purification filter cloth 5 is located at the top of the air guide holes 11 and is located between the isolation plate 42 and the guide plate 6. The air guide holes 11 and the ventilation holes 13 are connected.

[0036] The above technical solution is adopted: the purification filter cloth 5 is located at the top of the air duct 11 and between the isolation plate 42 and the guide plate 6, which can effectively filter the incoming harmful gases and ensure the breathing safety of rescuers.

At the same time, it can also blow a certain amount of airflow on the protective lens 2 to reduce the possibility of fogging.

[0037] Preferably, in any of the above embodiments, the fastening piece 7 is made of an elastic metal material and is snapped into the inside of the protective goggles 1.

[0038] The above technical solution is adopted: the fastening plate 7 can firmly fix the guide plate 6, ensuring that it will not shake or fall off during use. Moreover, the properties of the elastic metal material give the fastening plate 7 a certain degree of flexibility, making it easy to install and remove the guide plate 6.

[0040] The above technical solution is adopted: the sealing gasket 8 is larger than the isolation plate 42 and is located inside the protective goggles 1. When the isolation plate 42 of the sealing partition 4 moves, the sealing gasket 8 moves accordingly. This not only enhances the sealing of the inside of the protective goggles and prevents harmful gases from leaking in, but also adjusts the space of the air chamber 9 during the movement. The air chamber 9 is used to compress the gas to form an airflow, which blows air onto the inside of the protective lens 2, further playing the role of anti-fogging and protection.

[0041] Preferably, in any of the above embodiments, the air chamber 9 and the air guide groove 10 are formed inside the protective goggles 1, the air guide groove 10 is connected to the air guide hole 11, and the air guide groove 10 is located below the purification filter cloth 5.

[0042] Using the above technical solution: when the sealing gasket 8 moves to compress the air chamber 9, the gas enters the air guide hole 11 through the air guide groove 10, forming a local rapid airflow. On the one hand, it can blow air to protect the protective lens 2, and on the other hand, it can help accelerate the air circulation inside the protective goggles, better realize the functions of heat dissipation, ventilation and anti-fogging, and improve the overall performance of the protective device.

[0043] The working principle of this utility model for a protective device used in mine rescue is as follows:

[0044] Rescuers first put on the protective goggles 1 using the tightening straps 12. Temperature sensors 3 on both the inner and outer sides of the protective lens 2 monitor the temperature in real time and transmit the data to the micro control unit. When a large temperature difference between the inner and outer sides of the protective lens 2 is detected, which may cause fogging, the micro control unit controls the electric telescopic rod 41 of the sealing partition 4 to extend or shorten, driving the isolation plate 42 to move and release the isolation between the inner and outer sides of the protective goggles 1. At this time, the outside air is filtered by the purification filter cloth 5 and enters the protective goggles 1 through the air guide hole 11 of the guide plate 6, interacting with the internal air, reducing the temperature difference and preventing the protective lens 2 from fogging. During the movement of the sealing partition 4, the sealing gasket 8 is displaced accordingly, squeezing the gas in the air chamber 9 and causing it to flow through the air guide groove 10 to the air guide hole 11, forming a local rapid airflow inside the protective goggles 1, blowing air onto the inner side of the protective lens 2 to further prevent fogging.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] 1. Temperature sensors 3 are installed on both the inner and outer sides of the protective lens 2 to detect the temperature in real time. The temperature difference between the inner and outer sides of the protective lens 2 is determined based on the temperature detection data. The movement of the sealing partition 4 is controlled according to the temperature difference. When the temperature difference is high, the isolation between the inner and outer sides of the protective goggles 1 can be released, allowing the air outside the protective goggles 1 to be purified by the purification filter cloth 5 and then interact with the air inside the protective goggles 1. This dissipates heat and ventilates the inside of the protective goggles 1, reduces the temperature difference between the inner and outer sides of the protective goggles 1, prevents the protective lens 2 from fogging, and ensures the safety and stability of the protective device.

[0047] 2. An air chamber 9 and an air guide groove 10 are opened inside the protective goggles 1. During the movement of the sealing plate 4, the sealing gasket 8 will move and be displaced. The displacement of the sealing gasket 8 can adjust the internal space of the air chamber 9 to compress a certain amount of gas, forming a local rapid airflow inside the protective goggles 1, which is conducive to blowing air onto the inside of the protective lens 2 and providing a certain degree of protection for the protective lens 2.
