Description

Technical Field

[0001] The utility model relates to the technical field of protective clothing, in particular to a cooling protective clothing for mine rescue personnel. Background Art

[0002] A mine usually refers to a place where useful mineral resources are mined on the surface or underground. Since mines are deep underground, major disasters such as collapses often occur in mines. At this time, mine rescue teams are needed to rescue the people. However, since the victims are unconscious or lack physical strength, it is difficult for them to lie steadily on the backs of the rescuers, and they may slip and sway from side to side. In addition, due to the inertial impact between the two people during the carrying process, the victims with fractures are prone to secondary injuries.

[0003] Based on the above problems, the existing patent announcement number CN211751904U discloses a protective clothing for mine rescue. By unfastening the shoulder straps, waist belt and several branch belts inserted on the fixed block, and then squatting, the companions help the victim onto the backpack, so that the victim sits on the fixed connection between the bag cloth and the main body of the garment. After successfully helping the victim onto the backpack, the shoulder straps, waist belt and several branch belts are respectively inserted and fixed in the fixed block, so that the rescuers can perform other actions while carrying the rescuer. At the same time, the victim can lie stably on the rescuer's back to avoid slipping and swaying left and right. Since the back of the main body of the garment is provided with an air bag, the mutual inertial impact of the two people can be weakened during the carrying process, so that the victims with fractures will not suffer secondary injuries.

[0004] However, when implementing the above-mentioned protective clothing for mine rescue, it was found that there were at least the following problems: fires are very likely to occur in mines, especially in some coal mines. At this time, it can often be found that before going down into the mine, the rescuers will first wear protective clothing, and then wet the protective clothing by spraying with a high-pressure water gun to prevent the rescuers from being affected by the high temperature during the mine rescue. Although the protective clothing can isolate most of the heat, the protective clothing cannot cool down by itself, and the high temperature will still make the rescuers feel uncomfortable. Therefore, the protective clothing will be wetted before the rescue. However, the protective clothing is generally coated with a waterproof coating, which also results in the wet protective clothing being unable to maintain for a long time, and its cooling effect is not good. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a cooling protective clothing for mine rescue personnel, which can enable the protective clothing to maintain the cooling effect for a longer period of time, so as to solve the problem in the prior art that the protective clothing wetted by spraying with a high-pressure water gun cannot be maintained for a long time due to the influence of the waterproof coating, resulting in poor cooling effect.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a cooling protective suit for mine rescue personnel, comprising: a protective suit body, a water-absorbing layer sandwiched inside the protective suit body; a water storage backpack, the water storage backpack is sewn on both sides of the chest of the protective suit body, the water storage backpack extends along the shoulders of the protective suit body to the back of the protective suit body, a water connecting pipe is fixed on the water storage backpack, a pressure water source can inject water into the water storage backpack through the water connecting pipe, and the water storage backpack is connected to the water-absorbing layer; drainage holes are provided at the hem of the protective suit body and the cuffs of the protective suit body, drainage buckles are provided on the drainage holes, drainage buckles are buckled with drainage mother buckles, the drainage mother buckles are fixed to the connecting belt, and the connecting belt is sewn to the protective suit body.

[0007] Optionally, exhaust holes are provided on the shoulders and elbows of the protective suit body.

[0008] Optionally, the protective clothing body includes an outer waterproof layer, a middle insulating layer and an inner interior layer, and the water-absorbing layer is located between the waterproof layer and the insulating layer.

[0009] Optionally, the water-absorbing layer is made of fiber cloth.

[0010] Optionally, the water-absorbing layer and the water storage backpack weigh less than 5 kg after storing water.

[0011] Optionally, a first reflective strip is provided on the back of the protective suit body and on the cuffs of the protective suit body.

[0012] Optionally, a second reflective strip is provided on the back of the protective clothing body.

[0013] Optionally, the protective clothing body and the second reflective strip are bonded by Velcro.

[0014] Compared with the prior art, the utility model provides a cooling protective clothing for mine rescue personnel, which has the following beneficial effects:

[0015] 1. The utility model fills the water storage backpack with water through a water pipe. Due to the water absorption layer and the relatively sealed interior of the protective suit, the water in the water storage backpack can be slowly absorbed by the water absorption layer, so that the water is distributed around the protective suit. Later, when the rescuers are rescuing, the water in the water absorption layer absorbs heat and continuously cools down the rescuers. The cooling effect can be maintained for a longer time than directly wetting the protective suit, which solves the problem in the prior art that the protective suit sprayed with a high-pressure water gun cannot be maintained for a long time due to the influence of the waterproof coating, and the cooling effect is poor;

[0016] 2. The utility model provides exhaust holes on the shoulders and elbows of the protective suit body, so that even if the high temperature evaporates the water, the water vapor can be discharged from the exhaust holes on the shoulders and elbows of the protective suit body, preventing the water vapor from scalding the face or neck of the rescuer;

[0017] 3. The utility model provides a second reflective strip on the back of the protective clothing body, and the protective clothing body and the second reflective strip are bonded by Velcro. The second reflective strip can be tied to the injured arm or held by the injured, so as to observe the movement of the injured during rescue. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 This embodiment provides a cooling protective suit for mine rescue personnel, including a protective suit body 1 and a water storage backpack 3. The protective suit body 1 has a water absorbing layer 2 sandwiched therein. Compared with most protective suits in the prior art that have a waterproof layer or a waterproof coating on the outer layer, in this embodiment, the water absorbing layer is sandwiched in the protective suit body, so that the water absorbed by the water absorbing layer 2 will not flow out of the protective suit body 1 in a short time.

[0025] The water storage backpack 3 is sewn on both sides of the chest of the protective suit body 1, and the water storage backpack 3 extends along the shoulder of the protective suit body 1 to the back of the protective suit body 1, so that the water storage backpack 3 can be more evenly stressed after storing water, and will not cause the rescuer to lean forward or backward. A water receiving pipe 4 is fixed on the water storage backpack 3, and the pressure water source can inject water into the water storage backpack 3 through the water receiving pipe 4. The water storage backpack 3 is connected to the water absorption layer 2. It should be noted that the amount of water filled in the water storage backpack 3 should not be too much, otherwise it will easily affect the rescuer's load-bearing, and the rescuer's reciprocating time is limited, so there is no need to fill too much water, and it can be maintained for 1-2 hours.

[0026] The hem of the protective suit body 1 and the cuffs of the protective suit body 1 are both provided with drainage holes 5, and drainage buckles 6 are provided on the drainage holes 5. The connecting belt 8 is sewn to the protective suit body 1, and the drainage mother buckle 7 is fixed to the connecting belt 8. The drainage buckle 6 is buckled with the drainage mother buckle 7. Through the drainage mother buckle 7 and the drainage buckle 6, part of the water can be discharged after use to accelerate the drying process.

[0027] The cooling protective clothing for mine rescuers using the above structure, when rescue is needed and accompanied by high temperature or open flame, the rescuers can first wear the protective clothing body 1, and then fasten the drainage mother buckle 7 on the connecting belt 8 onto the drainage sub-buckle 6 to close the drainage hole 5, and then fill the water storage backpack 3 with water through the water connecting pipe 4. Due to the water absorption layer 2 and the relatively sealed interior of the protective clothing body 1, the water in the water storage backpack 3 can be slowly absorbed by the water absorption layer 2, so that the water is distributed around the protective clothing body 1. Later, when the rescuers are rescuing, the water in the water absorption layer 2 absorbs heat and continuously cools down the rescuers. The cooling effect can be maintained for a longer time than directly wetting the protective clothing, which solves the problem in the prior art that the protective clothing wetted by spraying with a high-pressure water gun cannot be maintained for a long time due to the influence of the waterproof coating, and its cooling effect is poor.

[0028] Please refer to Figure 2 and Figure 3During the rescue process, due to the influence of water evaporation, if water vapor evaporates along the damaged part of the protective suit body 1 due to heat, it is easy to scald the rescuer's face or neck. Generally, a helmet is worn, and the impact on the head is relatively low. In order to allow the water in the water absorption layer 2 to be discharged in an orderly manner during evaporation, exhaust holes 9 are provided on the shoulders of the protective suit body 1 and the elbows of the protective suit body 1. In this way, even if the high temperature evaporates the water, its water vapor can be discharged from the exhaust holes 9 on the shoulders of the protective suit body 1 and the elbows of the protective suit body 1 to prevent scalding. It should be noted that even if the water in the water absorption layer 2 slowly flows out from the exhaust holes 9, it only shortens the cooling time of the water absorption layer 2. Compared with scalding, the exhaust holes The setting of 9 has more advantages than disadvantages, and the water storage capacity in the water storage backpack 3 will not be too much, and the water slowly flowing out from the exhaust hole 9 will not be too large, and the impact is relatively low. It is particularly important to note that during the rescue process, if the shoulders are carrying injured persons, the injured persons are pressed on the shoulders of the protective clothing body 1 and are less likely to be scalded. Most of the water vapor can be discharged along the exhaust holes 9 on the elbows of the protective clothing body 1, and the temperature of the water vapor discharged from the exhaust holes 9 will not be too high. Under extremely high temperature conditions, if the water vapor discharged from the exhaust holes 9 can reach the level of scalding the injured persons, there is basically no need to consider the scalding problem if the injured persons have no other protective measures, and the life safety of the rescuers is given priority.

[0029] Please refer to Figure 4 In order to further reduce the impact of high temperature on rescuers, the protective clothing body 1 includes an outer waterproof layer 101, a middle insulating layer 102 and an inner interior layer 103. The interior layer 103 is generally suitable for contact with the body. The waterproof layer 101 and the thermal insulation layer 102 are both existing technologies. The specific waterproof and thermal insulation methods are not described in detail here. By locating the water-absorbing layer 2 between the waterproof layer 101 and the thermal insulation layer 102, the waterproof layer 101 will first resist part of the high temperature. After the high temperature passes through the waterproof layer 101, the thermal insulation layer 102 can block the subsequent temperature and reduce the impact of the high temperature on the rescuers.

[0030] Please review Figure 4 Fiber cloth is generally of low cost, and most of the fiber cloth has good water absorption, and is generally used in toiletries, such as towel cloth, non-woven fabrics, etc. By making the water-absorbing layer 2 of fiber cloth, the cost can be reduced, and at the same time, the good water absorption of the water-absorbing layer 2 is ensured. The water-absorbing layer 2 can also be a better water-absorbing material such as sponge, but considering the weight of the protective clothing body 1 after absorbing water, it does not need to have too good water absorption.

[0031] Please review Figure 2 and Figure 3In order to ensure that the weight of the protective suit body 1 after absorbing water does not affect the actions of the rescuers, the weight of the water absorption layer 2 and the water storage backpack 3 after storing water must be less than 5kg. The amount of water poured in can be that after the protective suit body 1 is dried, 5kg of water is poured into the water storage backpack 3 so that the water in the water storage backpack 3 flows into the water absorption layer 2, or the water storage backpack 3 can only hold water weighing 5kg.

[0032] Please review Figure 2 and Figure 3 In order to facilitate observation of the rescue personnel ahead in the dark and prevent them from falling behind, a first reflective strip 10 is provided on the back of the protective suit body 1 and the cuffs of the protective suit body 1.

[0033] Please review Figure 2 and Figure 3 Considering that there is no reflective strip on the injured person's clothes, which makes it inconvenient to observe the injured person during subsequent rescue, a second reflective strip 11 is provided on the back of the protective clothing body 1. The protective clothing body 1 and the second reflective strip 11 are bonded by Velcro 12. The second reflective strip 11 can be tied to the injured person's arm or let the injured person hold it, so as to observe the injured person's movements during rescue.

[0034] When rescue is required in a high temperature or open flame environment, the rescuer first puts on the protective suit body 1, then fastens the drainage mother buckle 7 on the connecting belt 8 onto the drainage sub-buckle 6, closes the drainage hole 5, and then pours an appropriate amount of water into the water storage backpack 3 through the water connecting pipe 4. Due to the presence of the water absorption layer 2 and the relative sealing of the inside of the protective suit body 1, the water will be slowly absorbed by the water absorption layer 2 and evenly distributed around the protective suit body 1. During the rescue process, the heat generated by the rescuer's body is absorbed by the water in the water absorption layer 2, achieving continuous cooling. Compared with directly wetting the protective clothing, this method can maintain a longer cooling effect. At the same time, in order to prevent the water vapor generated by evaporation from scalding the rescuers, exhaust holes 9 are set on the shoulders and elbows of the protective clothing body 1. Water vapor can be discharged in an orderly manner from these exhaust holes 9 to reduce the risk of scalding. The protective clothing body 1 is composed of a waterproof layer 101, a heat-insulating layer 102 and an interior layer 103. The waterproof layer 101 first blocks part of the high temperature. After the high temperature passes through the waterproof layer 101, the heat-insulating layer 102 further blocks the heat to reduce the impact on the rescuers. The water-absorbing layer 2 is made of fiber cloth and other materials, which is low in cost and has good water absorption. In order not to affect the actions of the rescuers, the total weight of the water-absorbing layer 2 and the water storage backpack 3 after water storage is controlled below 5kg. In order to facilitate observation in a dark environment, a first reflective strip 10 is set on the back and cuffs of the protective clothing body 1 to facilitate the observation of the rescuers in front, and the second reflective strip 11 can be used to tie up the injured or let the injured hold it, so as to facilitate the observation of the injured's movements.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
