Description

Technical Field

[0001] The invention belongs to the technical field of personal protective equipment in mines, and relates to a long-acting refrigeration and cooling suit for individual intelligent protection of miners in high-temperature and high-humidity metal mines. Background Art

[0002] Metal mineral resources are an important guarantee for construction and have an extremely important strategic position. They are the primary consumables for infrastructure construction and are also indispensable raw materials for transportation, energy, chemical industry, aerospace, military industry and other departments. As the output of shallow resources can no longer meet people's needs, more and more mines are turning to deep mining. With the increase in depth, high temperature and high humidity have inevitably become a major problem in the mining of metal mineral resources. High temperature and high humidity environment will have a direct impact on the physiological functions of miners. Working in a hot and humid environment for a long time, miners are prone to heat stress reactions such as heat stroke and heat exhaustion, and in severe cases may even cause fatal diseases such as heart disease and stroke. In addition, high temperature will increase the evaporation of water of miners, leading to dehydration, further aggravating physical discomfort. High humidity environment will slow down the evaporation rate of sweat, making it difficult for miners to effectively dissipate heat through sweating, thereby exacerbating the negative impact of high temperature environment. Therefore, the research on personal protection technology and equipment for heat damage in mines is particularly important. Personal protective cooling clothing is a solution directly for miners. It usually integrates a cooling system in the protective clothing to prevent overheating by absorbing the heat generated by the human body.

[0003] However, there are some problems with current cooling suits, including heavy system weight and bulky equipment, which are inconvenient for miners to move underground; complex system structure, which may cause leakage problems in the harsh environment underground; lack of effective perspiration mechanism, which affects comfort; short duration, frequent replacement of cooling source, which brings additional burden to miners; lack of intelligent control, and inability to automatically adjust according to the actual body temperature and ambient temperature of miners. In order to solve these problems, it is necessary to design intelligent protective equipment that better meets human needs. The application of semiconductor refrigeration technology provides a new idea for solving the cooling problem of miners. By optimizing the combination of refrigeration devices and clothing, the weight can be reduced and the portability and reliability of the system can be improved; phase change cooling suits are widely used due to their simple structure, strong cooling capacity, and low pollution. The surface of the composite phase change material does not change, which can effectively solve the leakage and packaging problems of individual phase change cooling materials for mining. At the same time, the advancement of control technology enables the refrigeration system to be dynamically adjusted according to the actual heat load of the miners to maintain the best thermal comfort.

[0004] In summary, the invention of an intelligent integrated long-term refrigeration and cooling suit that can operate in high temperature and high humidity environments can reduce the limitations of existing cooling suits through technological innovation and optimized design, and ensure the safety and health of miners. This is not only crucial for the welfare of miners, but also an important way to promote safe production and economic benefits in coal mines. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an individual intelligent protective long-term refrigeration and cooling suit for miners in high-temperature and high-humidity metal mines, which can be used to provide good working conditions for miners when working in high-temperature and high-humidity environments in metal mines. The refrigeration suit can use a vital sign detection bracelet to detect various index parameters inside and on the human body, and at the same time monitor the temperature, humidity and toxic and harmful gases in the external environment. When a certain index parameter exceeds the limit, an alarm will be issued; when the human body feels hot or the external temperature is too high, the temperature regulation system will be automatically turned on, mainly including phase change cooling, semiconductor cooling and fan cooling, to adjust the microenvironment on the human body surface to achieve suitable working conditions, and ultimately achieve the purpose of ensuring human health and work safety.

[0008] The helmet has a positioning function and is equipped with a searchlight, goggles, a half-breathing mask and an intercom; the searchlight is located on the outer side of the upper front of the helmet, and the intercom is located on the outer side of the left part of the helmet. Both the searchlight and the intercom are connected to the intelligent controller and have independent power supplies; the half-breathing mask is detachable and has dust and gas prevention functions;

[0009] The collar of the jacket is provided with a fan to accelerate the heat dissipation and ventilation inside the cooling suit; the right shoulder of the jacket is provided with an environmental monitor to monitor the external wind flow, temperature and humidity and the content of various toxic and harmful gases;

[0010] The recorder is arranged at the left chest of the jacket, and is used to continuously record and store external conditions; the vital sign detection bracelet is arranged at the right cuff of the jacket, and is used to continuously detect life characteristic parameters; the intelligent controller is arranged at the left cuff of the jacket, and is connected to the fan, environmental detector, alarm light, collaborative controller, recorder, and vital sign detection bracelet for synchronous regulation; the collaborative controller and power supply are both arranged at the lower back of the jacket, and the power supply supplies power to the collaborative controller, the intelligent controller, and other electrical equipment; the small oxygen cylinder is arranged on the right side of the pants, and is connected to the half-breathing mask to provide oxygen when necessary;

[0011] Both the top and the pants have a four-layer structure, which are, from the outside to the inside, a buffer layer, a moisture-proof layer, a cooling layer, and a breathable layer. The buffer layer is composed of a buffer material to reduce impact damage; the moisture-proof layer is composed of a porous hygroscopic material to prevent external moisture from reaching the body surface while also being breathable; the cooling layer is composed of a semiconductor cooling sheet and a phase change cooling material to achieve a cooling effect when the body surface temperature is too high; the breathable layer is composed of an affinity breathable material, and a temperature measuring sheet is installed on the side close to the body surface to monitor the body surface temperature.

[0013] Furthermore, the middle of the front of the top is connected by a magnetic button.

[0014] Furthermore, the vital sign detection bracelet is connected to the intelligent controller to display the detection results on the intelligent controller.

[0015] Furthermore, the power source is a new energy battery, and a battery pocket is sewn on the back of the protective clothing for placing the power source; a charging port is opened at the upper right corner of the battery pocket.

[0016] Furthermore, the upper part of the trousers is tightened at the waist by a belt.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention can effectively cope with the harsh environment of high temperature and high humidity in mines through the design of multi-layer structure and the combination of multiple cooling methods. The cooling layer of the clothing adopts a combination of semiconductor cooling sheets and phase change cooling materials, which not only quickly cools down the miners when their body temperature rises, but also maintains the miners' thermal comfort by automatically adjusting the body surface microenvironment. This intelligent temperature regulation capability significantly reduces the health risks of miners such as heat stroke and dehydration caused by the hot environment, and improves the safety of mine operations.

[0021] 2. The present invention significantly reduces the overall weight of the system by using lightweight materials and modular design. At the same time, the protective clothing uses magnetic buttons, and the cuffs and trouser legs are equipped with tightening belts to increase convenience. The design of the buffer layer, moisture-proof layer and breathable layer in the multi-layer structure not only improves the comfort of the protective clothing, but also effectively prevents the entry of external moisture, avoiding discomfort caused by moisture to miners.

[0022] 3. The present invention integrates phase change cooling materials and semiconductor cooling sheets to extend the cooling duration of the cooling suit. Phase change materials have a high cold storage capacity and can provide cooling for miners for a relatively long time, reducing the frequency of changing cooling sources. At the same time, the application of new energy batteries provides continuous and stable power support, ensuring that the equipment can run uninterruptedly during long-term work, meeting the needs of miners working underground for a long time.

[0023] 4. The intelligent control system and vital sign detection bracelet equipped in the present invention can be intelligently controlled according to the miner's vital signs such as body temperature, heart rate, and changes in external temperature and humidity, and automatically start or shut down the cooling system. When the miner is in an overheated or other dangerous state, the system can automatically adjust the cooling power to keep the body temperature stable. In addition, the alarm light can issue an early warning when the miner's vital signs or environmental parameters are detected to be out of limit, providing immediate protection for the miner and reducing safety hazards caused by emergencies.

[0024] 5. The protective clothing of the present invention adopts multi-layer buffer materials in structural design, which can effectively reduce the damage caused by external physical impact to miners. In addition, the positioning device and walkie-talkie and other additional equipment equipped with the helmet provide convenience for miners' communication and positioning underground, help to deal with emergencies in mines, and improve rescue efficiency and safety.

[0025] 6. The present invention utilizes the efficient cold storage characteristics of phase change materials to avoid the high energy consumption problem of traditional refrigeration systems. At the same time, the use of new energy batteries instead of traditional batteries reduces energy consumption and meets the needs of energy conservation and environmental protection. In addition, the material selection of the cooling suit is environmentally friendly and pollution-free, which conforms to the design concept of green environmental protection and meets the requirements of mine environmental protection.

[0026] 7. The recorder of the present invention can store the external environment and physical sign monitoring data in real time, providing data support for subsequent work. Through long-term data accumulation, the law of the impact of high temperature and high humidity environment on the miners' body can be analyzed, the protection design can be further optimized, and a reliable safety basis can be provided for the management department.
