Description

A kind of intelligent wearable equipment for coal occupational disease protection

technical field

The utility model relates to an intelligent wearing equipment for coal occupational disease protection, which is a kind of protective equipment, and is a kind of equipment for protecting human health and preventing occupational diseases in coal.

Background technique

The environment in the mine is very harsh. A large amount of dust, harmful gases, noise of working machinery and high temperature and humidity have formed the "four hazards" of underground work. The four hazards seriously endanger the health of underground workers and must be prevented. The traditional ways to prevent and control the four pests are:

(1) Filtering face mask or mask. The disadvantage is that the mask or mask needs to be tightly fixed with the head, and the wearing comfort is poor; the coal application scene is extremely harsh, especially the dust concentration in the air of the working face is very large, the dustproof effect is not ideal, and the incidence of pneumoconiosis cannot be effectively reduced; It cannot effectively filter harmful gases such as carbon monoxide, methane, hydrogen sulfide, sulfur dioxide, nitrogen oxides, etc., and the protective effect of harmful gases is weak, and it cannot effectively prevent the harm caused by harmful gases to the human body.

(2) Isolated face mask or mask, supporting breathing air supply system. The disadvantage of the isolation mask or mask is that the isolation effect is not good, and it cannot completely isolate the dust and harmful gases in the external environment. There are three main types of breathing air supply systems matched with isolated masks or masks: 1. Portable compressed oxygen cylinders or chemical oxygen reaction generators, which provide higher concentrations of oxygen to supply human breathing needs. The disadvantage is that long-term breathing of higher concentrations of oxygen, It will cause oxygen poisoning or other diseases to the human body, so this breathing oxygen supply system is often used as temporary emergency rescue equipment and cannot be popularized in long-term continuous operations; 2. Portable compressed air bottle, providing pure air to supply human breathing needs , due to the limited volume of the portable compressed air bottle, and the oxygen volume fraction in the air is only about 21%, in fact, the amount of oxygen carried each time is very limited, so the continuous operation time is short, which is limited in application; three 、Fixed compressed air bottle, providing pure air to supply human breathing needs, the fixed compressed air bottle can store a larger capacity of pure air, the disadvantage is that the fixed compressed air bottle and the operator need to use a long breathing tube connection, so the personnel The work can only be carried out within a short distance near the stationary compressed air bottle, and the maneuverability is limited.

(3) Completely isolated mouthpiece and nose clip, supporting the breathing air supply system. Completely isolated mouthpiece and nose clip Use the nose clip to close the channel for breathing through the nose, and only breathe with the mouthpiece, which can completely isolate the dust and harmful gases in the external environment, but it violates human breathing habits, so it needs to be used before use. Carry out special training and are often used as temporary emergency rescue equipment. There are mainly three types of respiratory air supply systems matched with completely isolated mouthpieces and nose clips, which are exactly the same as those matched with isolated face masks or masks, and will not be repeated.

(4) Equipped with earplugs to protect against noise, which can isolate noise, but it also isolates the way of information communication with other people, which is extremely inconvenient to use.

The existing technical solutions are mainly aimed at the protection of the breathing process, and mainly for the protection of dust. Most of the equipment is powerless against harmful gases, and completely unable to protect the human body from the impact of high temperature and humidity. "Four pests" play a technical solution for comprehensive protection.

Detailed ways

Example 1:

This embodiment is an intelligent wearable equipment for coal occupational disease protection, as shown in Figures 1, 2, and 3. This embodiment includes: a protective suit 2 with a helmet 1 and an inner space, a pure oxygen source 4 communicated with the helmet through an oxygen valve 3; an air source 6 communicated with the inner space of the protective suit through an air valve 5, the said The electrical control ends of the air valve and the oxygen valve are electrically connected to the controller 7, and the controller is electrically connected to the oxygen concentration sensor 8 arranged in the helmet. The protective suit is also provided with an air circulation device 9, the air circulation device includes an air inlet 901 communicating with the inner space of the protective suit, and the air inlet passes through a pipeline (the thick solid line in FIG. 2). Represents the pipeline) in turn with the filter 902 of the air circulation device, the air circulation pump 903 (the part of the dotted line frame in FIG. 2 ) and the air outlet 904 communicated with the inner space of the protective clothing; the lower part of the protective clothing is also There is a pressure relief valve 10 in which the inner space of the protective suit communicates with the atmosphere, as shown in FIG. 2 .

The purpose of the intelligent wearing equipment for coal occupational disease protection described in this embodiment is to establish an inner space isolated from the outside in the protective clothing. This internal space has clean air for breathing, is suitable for the temperature and humidity of the human body, and isolates external noise, providing a comfortable environment for underground workers to work for a long time, and can avoid or reduce the occurrence of emergencies. damage equipment. Due to the clean air, personnel can be completely free from silicosis and toxic air, temperature and humidity control can prevent personnel from being troubled by damp heat, and noise isolation can prevent personnel from deafness and other ear diseases.

The difficulty and key of this embodiment is to provide a long-term supply of clean air. The mine is a closed and narrow working environment, and the dust on the working surface is often concentrated and difficult to disperse. If a filter is used, it will soon become blocked in such an environment, making it unusable. If traditional compressed air cylinders are used, it will only last for a short time. If you use pure oxygen compressed gas cylinders, you may face many problems such as oxygen poisoning.

This embodiment provides a technical solution capable of supplying pure air for a long time: a pure oxygen source is used to provide mutually used oxygen, and an air source is used to provide partially clean air to mix the two. The oxygen in the pure air comes from a compressed oxygen bottle or a chemical oxygen generator, and the nitrogen comes from a small compressed air bottle or compressed nitrogen bottle (nitrogen is not consumed in the process of human breathing, so nitrogen can be used in a small gas bottle to adjust the gas supply The ratio of oxygen and nitrogen in the medium to meet the needs of human breathing), the oxygen concentration sensor monitors the oxygen concentration in the breathing air supply system in real time, and transmits the oxygen concentration signal to the processor, and the processor adjusts and controls the oxygen and nitrogen in time according to the oxygen concentration information. The proportion of air supply to make it meet the needs of human breathing. When a person breathes, carbon dioxide is produced. Since oxygen and air or nitrogen must be continuously supplemented in the helmet, the carbon dioxide exhaled by the person can be squeezed out of the helmet, so that the carbon dioxide in the helmet can be maintained at a safe level, while being squeezed by oxygen and air The carbon dioxide coming out of the helmet is filtered out by the filter of the air circulation device in the inner space of the protective clothing, so as to keep the air in the inner space of the protective clothing fresh. To further prevent excessive carbon dioxide, a carbon dioxide concentration sensor 101 (see Figure 3) can be installed in the helmet. When the carbon dioxide in the helmet exceeds a certain limit, the supply of oxygen or air is increased to keep the air in the helmet fresh.

In addition, the pure oxygen gas source and air gas source also need to be equipped with safety components such as pressure gauges, alarms, safety valves, etc., so that the entire system can operate safely and reliably. When the oxygen source is insufficient, the alarm will alarm, reminding to replace the compressed oxygen cylinder or chemical oxygen generator in time. The safety valve sets the upper pressure limit for the compressed oxygen cylinder or chemical oxygen generator and plays a protective role.

An oxygen source and an air source can also be connected to the drug delivery device 401 . The role of the drug delivery device is to add some drugs to clear the lungs in the air, increase the aerosolized drugs, and treat respiratory and skin diseases. The dosing device can be connected to a pure oxygen oxygen source, as shown in FIG. 3 , and a bypass selection valve 402 is added, and the bypass selection valve is electrically connected to the controller.

The main body of this embodiment is a protective suit with a helmet. The body part of the protective clothing is made of soft materials, and has the ability to insulate, as well as considerable toughness, and has a certain ability to resist puncture by sharp substances. The material of the protective clothing must be light enough to allow the person to move freely after wearing the protective clothing. The difference between protective clothing and general clothing is that there is space for air flow inside, which is very important. Only when the air can flow in the protective clothing can it have the ability to take away the heat emitted by the human body. Since the protective clothing is insulated, the external heat cannot enter the protective clothing, and the heat inside cannot be directly released to the outside, but the human body will release heat. If there is no channel for the release of human body heat, people cannot live normally. Not to mention work. Therefore, the key of this embodiment is to provide the inner space of the protective suit allowing air flow.

In addition to expelling the heat released by the human body, the inner space of the protective clothing has a more important role in assisting breathing. The solution for human breathing in this embodiment is to combine air in a limited space with pure oxygen and carbon dioxide exhaled by the human body to form air suitable for human breathing. This limited space has to be large enough to get good air mixing. If only relying on the space in the helmet is not enough, this embodiment combines the helmet and the body part of the protective suit to form a space sufficient to accommodate a certain amount of air, and an exhaust port is set far from the output port of pure oxygen, so that the Part of the air with lower oxygen concentration is expelled, allowing the inner space of the suit to include fresh air.

In order to keep the air fresh in the inner space of the protective clothing, an air circulation device is also provided in this embodiment. In order to keep the air in the inner space of the protective clothing fresh, the air circulation device is equipped with filtration, cooling, dehumidification and other facilities to maintain the small environment in the protective clothing suitable for human activities.

The filter can absorb the bad parts in the air such as carbon dioxide discharged by breathing and odor in the system, and keep the inner space of the protective clothing clean and fresh. The filter can also be used as a redundant setting of the system. In case of special circumstances such as the failure of the internal space seal of the protective clothing, it can absorb the dust entering the internal space of the protective clothing, maintain the breathing air supply function of the system, and wait for repair. Under normal circumstances, because the filter only absorbs some substances with smaller particles, it has a long life and can be reused. After a certain period of time, the filtration efficiency will decrease, and the filter can be restored by heating and baking. capacity, thereby reducing the cost of using protective equipment.

In this embodiment, temperature and humidity sensors 11 and 12 are set. As shown in FIG. 2 , the controller intelligently controls the temperature and humidity of the inner space of the protective clothing according to the temperature and humidity information transmitted by these sensors: when the inner space of the protective clothing is When the humidity exceeds a certain value, the controller will automatically turn on the dehumidification function according to the feedback signal of the humidity sensor, absorb excess water vapor, and keep the air humidity in the system within a certain range, neither too humid nor too dry, so that the The wearer gets a more comfortable feeling.

The dehumidification function can be realized by setting the water vapor separator 905, the water vapor bypass pipeline 906, and the water vapor separation valve 907 and other components, as shown in FIG. 2 . The electric control end of the water vapor separation valve is electrically connected with the controller. When the humidity is too high, the controller controls the water vapor separation valve to select the water vapor separator, so that the circulating air passes through the water vapor separator to filter out the moisture in the air; when the air humidity is suitable, the water vapor separation valve selects the water vapor bypass The pipeline, that is, the circulating air does not pass through the water vapor separator, and directly enters the inner space of the protective clothing to ensure that the air humidity is suitable.

The temperature control function can be achieved by arranging a radiator 910 with a louver 908 and a fan 909 on the air circulation line, as shown in FIG. 2 . The radiator may be a tube bundle heat exchanger. The air passes through the tube bundle and conducts heat to the fins on the tube bundle, which transfer the heat to the atmosphere. The heat dissipation on the heat sink can also be accelerated by the fan, so a fan and a louver can be arranged on the heat exchanger, and the louver is provided with an opener 911 for controlling the opening of the louver (see Figure 2), and the fan and the opening are connected. The shutter is electrically connected with the controller. When the temperature of the inner space of the protective clothing increases, the shutter controls the shutter to open, and if necessary, the fan is turned on to accelerate heat dissipation. A cooling device, such as a semiconductor refrigeration sheet 912 (see Figure 2) or a micro cooling pump, can also be provided on the heat exchanger to make the heat exchanger a refrigerator, so that the inner space of the protective clothing can maintain a suitable temperature for the human body.

A safety helmet is required in the mine, therefore, the helmet described in this embodiment must also have the function of a safety helmet, as well as functions such as communication and lighting, which is different from the usual sealed protective clothing. In order to prevent the impact of heavy objects, the top of the helmet described in this embodiment is made of impact-resistant material lined with buffer material, the face is made of transparent impact-resistant material for heat insulation and sound insulation, and the other parts are impact-resistant materials, lined with heat insulation and sound insulation materials. , the neck is completely integrated with the inner space of the protective clothing. At the same time, the helmet is also provided with a wireless voice communication device 102 and a headlight 103 for lighting, as shown in FIG. 1 .

The protective suit also comes with gloves 201 capable of operating the touch screen and rubber boots 202 with anti-smash, waterproof and insulating capabilities. The gloves and rubber boots described in this embodiment are isolated from the inner space of the protective clothing, that is to say, after the protective clothing is worn, the hands and feet are exposed to the outside, and the inner space of the protective clothing is sealed on the forearm and the calf. This is for operation Other equipment is convenient, unlike most other protective clothing.

The gloves and rubber boots described in this embodiment can be conventional gloves and rubber boots, or can be a heat dissipation pipe connected with the pipeline of the air circulation device, so as to eliminate the excess heat generated by the hands and feet during activities.

In order to make the whole equipment lighter and easier to maintain, some equipment that often needs to be maintained and replaced can be integrated into a backpack 13 (see the part of the dotted box in Figure 2), such as compressed air cylinders or compressed nitrogen cylinders and compressed oxygen cylinders Or chemical oxygen generators, controllers and batteries 14, and circulation pumps, cooling equipment, dehumidification equipment, etc. of the air circulation device.

The overall equipment is made of flame-retardant and anti-static materials, so it has the ability to work in special environments. Therefore, the equipment described in this embodiment can not only be used in the coal industry, but also in the non-coal industry, metal mines, cement, construction It has a significant effect on preventing occupational pneumoconiosis in workplaces with severe dust such as construction sites.

This embodiment has the characteristics of a lightweight portable breathing air supply system, has the ability of complete isolation protection, can prevent four evils, has complete functions, its operation is completely intelligent, and it is very convenient to disassemble, clean, maintain and repair, and has good economy. Take into account the continuous operation and emergency emergencies.

Embodiment 2:

The embodiment is a coal occupational disease protection method using the equipment described in the first embodiment. The method described in this embodiment adopts intelligent wearable equipment for coal occupational disease protection that is completely isolated from the outside world, which is more effective and more stable than the most commonly used filtering protective equipment. The harsh working environment ensures the health of the workers. A set of intelligent wearable equipment for coal occupational disease protection is fully functional, and can play a comprehensive protective role against the "four hazards" of occupational diseases in the coal industry, including dust, harmful gases, noise, and heat hazards. The equipment is completely intelligent, no manual operation is required, and the changes in temperature, humidity and oxygen concentration in the system are intelligently sensed through sensors, and fed back to the processor in time to adjust the speed of the motor and the fan, whether the steam-water separator is connected, and whether the radiator fan is turned on. , the opening of the radiator shutters, and the adjustment and control of the ratio of oxygen and nitrogen in the breathing air supply, etc., to keep the temperature, humidity and oxygen concentration in the system within a more comfortable range. In equipment and system design, factors such as economy are taken into account, such as the reusability of multi-functional filters, etc., so as to reduce the use cost of equipment throughout its life cycle.

The method described in this embodiment includes the following specific steps, and the process is shown in Figure 3:

Step S1, wear equipment: wear protective clothing, airtight the wrists and ankles, put on rubber shoes and gloves, connect the cooling pipes of the rubber shoes and gloves, put on the backpack to connect the pipeline and circuit, and connect the helmet pipeline and circuit.

The process of putting on the equipment is to wear the body part of the protective suit first, and then put on the backpack to connect the pipeline and circuit. The key to donning is the sealing of the arms and legs, which completely isolates the inner space of the suit from the outside. The wearing of protective clothing should be mainly self-wearing, with the help of others to wear, and avoid the design that is completely assisted by others.

Step S2, start the controller: start the controller to perform self-checking of the controller, and detect the status of each valve and sensor, the status of the wireless voice communication device, and the status of the headlight; turn on the air circulation device and detect the working state of the air circulation device.

Since the protective clothing is completely isolated from the outside world after wearing the helmet, the initial detection of the system is very important to communicate internal and external communications. Therefore, the communication methods inside and outside the protective clothing must be redundant, that is, there are several more communication methods, including wireless Communication, wired communication, gestures and other methods are used to ensure that after wearing the helmet, the wearer can fully communicate with the outside world, and can immediately express to the outside world once physical discomfort occurs. The ratio of oxygen and air should be pre-adjusted in the initial process to a level that allows people to breathe normally, so that they can breathe normally after wearing a helmet. However, since the oxygen concentration sensor is exposed to the atmosphere at this time, the dissolved oxygen inside the protective suit cannot be properly monitored, and it can only be used as a reference.

Step S3, put on the helmet: put on the helmet, connect the helmet to the protective clothing airtightly, and detect the working state of the entire equipment: open the oxygen valve and the air valve, and the controller adjusts the ratio of oxygen and air in the helmet through the oxygen concentration sensor. The temperature and humidity sensor adjusts the temperature and humidity of the inner space of the protective suit.

After wearing the helmet, the entire equipment is under fully automated monitoring. At this time, temperature, humidity, dissolved oxygen, etc. are under the monitoring of various sensors. In order to avoid danger, the helmet and the body part of the protective suit should be able to be quickly separated, and a safety valve that can be opened quickly is provided on the helmet, so that the wearer or other personnel can quickly communicate the helmet with the outside.

The following steps S4, 5, and 6 are performed at the same time, and the following three steps are the normal working state of the protective clothing:

Step S4, breathing control process: the controller monitors the oxygen concentration in the helmet in real time through the oxygen concentration sensor. Since the outlet of the oxygen tube is a certain distance from the mouth and nose, the human body is not inhaling pure oxygen, but a certain amount of nitrogen and carbon dioxide. Air, when the pure oxygen concentration is too large, input a certain amount of air. Since the outlets of the pure oxygen source and the air source are both set in the helmet, the pressure in the helmet increases and the pressure is output to other parts of the protective clothing. When the pressure in the inner space of the protective clothing is large enough, the pressure relief valve opens to discharge the excess gas in the air inside the protective clothing.

Since the breathing process of people mainly consumes oxygen, and other parts of the air are basically indigestible, this embodiment mainly supplies oxygen during the breathing control process, and at the same time uses the inner space of the protective clothing to provide the opportunity to mix air and oxygen. Provide air with a high oxygen concentration and suitable for breathing, while the air with a low oxygen concentration is discharged out of the protective clothing through the pressure relief valve. The air source is only turned on when the pressure of the inner space of the protective clothing is insufficient, and the shortage of air is supplemented, so it is used very little. Using this principle, both the oxygen consumption and the air consumption are saved, and the two air sources can be relatively reduced, and the lightweight is successfully achieved.

Step S5, temperature control process: the controller monitors the temperature of the inner space of the protective clothing in real time through the temperature sensor, and uses the opening or closing of the shutters, fans, and semiconductor cooling sheets as a strategy for dealing with temperature increases or decreases.

The main function of the inner space of protective clothing is to provide a space for air circulation. In the process of temperature control, air is a heat dissipation medium. Through the circulation of air, heat is taken away from the body and conducted into the atmosphere. The human body will generate heat during activities. If the heat is not dissipated in time, the human body will experience discomfort. The temperature sensor of the air circulation device takes the temperature of the inner space of the protective clothing as the detection object, which is equivalent to detecting the temperature of the human body. Through the controller automatically according to the data detected by the temperature sensor, the shutters are opened in sequence, the fan is further opened, and the cooling sheet is further opened to improve the cooling effect, or on the contrary, the cooling effect is reduced to maintain the temperature inside the protective clothing.

Step S6, humidity control process: the controller monitors the humidity inside the protective clothing in real time through the humidity sensor, and selects a linked water vapor separator or a bypass water vapor separator as a strategy to deal with the increase or decrease of the humidity.

The humidity control process of the inner space of the protective clothing mainly controls whether the circulating air passes through the water vapor separator. When the humidity is low, the circulating air is circulated through the bypass pipe, that is, no water vapor separation is performed.

Step S7, end: firstly open the helmet airtight, take off the helmet, then turn off the pure oxygen source, then turn off the air source, turn off the controller, take off the gloves and rubber boots, then take off the protective clothing, and separate the protective clothing from the backpack.

The end of the process starts with opening the helmet to allow the personnel to breathe natural air to ensure the safety of the personnel.

Finally, it should be noted that the above is only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred arrangement solution, those of ordinary skill in the art should understand that the technical solution of the present invention can be The solution can be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present invention.
