Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-rise building escape equipment, and particularly relates to a self-rescue escape equipment for high-rise building fire fighting. BACKGROUND

[0002] After a fire occurs in a high-rise building, personnel located in the high-rise building are difficult to be rescued. The existing fire fighting equipment is difficult to implement rescue for the personnel in the high-rise building in a short time, and can only rely on personnel self-rescue. The existing high-rise slow descending device adopts a centrifugal weight to form a friction force to brake to control the descending speed. When descending, a rope releases to drive an internal weight to rotate, a rotating object generates a centrifugal force to press on an inner surface of a shell to form a friction force, and the centrifugal force and the friction force have a friction coefficient relationship. Because the centrifugal force is proportional to the square of the angular velocity, when the descending drives the weight to rotate to a certain degree, the centrifugal force on the weight forms a normal pressure and further generates a friction force which is also increased to a certain degree, so that the descending speed cannot continue to increase, thereby achieving a uniform descending state.

[0003] The slow descending device has the following deficiencies: 1. a sudden descending process exists in the initial descending stage, so that the user has fear in heart; 2. the user cannot autonomously select to stop in the middle of the descending process to enter a balcony or a window of a lower floor, and the user cannot complete the escape in time; 3. the existing slow descending device only fixes the human body by using a safety belt, and the human body is exposed to the outside in the descending process. When a fire occurs in a high-rise building, the temperature around the human body is rapidly increased. If the human body does not wear a protective device to escape, the human body is easily roasted by high temperature to cause dehydration and death. Therefore, the temperature of the human body needs to be cooled to improve the escape probability. SUMMARY

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present application provides a self-rescue escape equipment for high-rise building fire fighting. In order to solve the problems that a sudden descending process exists in the initial descending stage, so that the user has fear in heart; the user cannot autonomously select to stop in the middle of the descending process to enter a balcony or a window of a lower floor, and the user cannot complete the escape in time; and the existing slow descending device only fixes the human body by using a safety belt, and the human body is exposed to the outside in the descending process.

[0016] The beneficial effects achieved by the above structure are as follows:

[0017] 1、The protective clothing body is arranged, after the escape personnel wears the protective clothing body, the outside fire is resisted, the activated carbon adsorption particle bag is placed in the anti-toxic filter cartridge, so that harmful substances in the air can be adsorbed, and the anti-toxic effect is achieved.

[0018] 2. In the main body of the descent device, the rope pulls the rope reel to rotate, which in turn drives the rotating rod to rotate, thereby driving the rotating disk to rotate. This causes the guide wheel to roll in the wave-shaped guide groove. The guide rod drives the piston rod on the damper to move back and forth. Due to the damping effect of the damper, the piston rod on the damper moves slowly, thereby slowing down the rotation of the rotating disk. This achieves the purpose of the rotating disk rotating at a uniform and slow speed, preventing a sudden drop in the initial stage of descent that could cause fear in the user.

[0019] 3. In the cooling component, the rotation of the rotating disk causes the second guide wheel to roll in the wave-shaped guide groove. The second guide rod drives the push rod to move back and forth, which in turn drives the piston to move back and forth in the extrusion cylinder. This continuously draws water from the water storage box into the extrusion cylinder through the suction pipe, and then sprays it out through the spray pipe, connecting pipe, annular pipe and nozzle. The water is sprayed onto the protective suit and the area around it, which helps to reduce the temperature around the escapee and thus increases the chances of survival.

[0020] 4. In the braking assembly, pressing down on the operating handle rotates the control arm, which in turn rotates the connecting arm and the swing arm. This causes the brake disc to contact the circumferential side wall of the rotating disc, generating friction and thus limiting the rotation of the rotating disc. This allows for deceleration and braking of the rotating disc at any time. Through the meshing of two sets of sector gears, both braking assemblies can work simultaneously, allowing escapees to choose to stop midway during the descent to access balconies or windows on lower floors, facilitating their escape.

[0021] 5. The backpack body is used to secure the descent device, and the backpack body and the protective clothing body are connected as one piece, which makes it convenient and quick to put on, saves dressing time, and increases the chance of escape.

[0022] 6. In addition to adjusting the descent speed through the damper, the main body of the descent device is equipped with a braking component. This not only buffers the descent speed in time but also provides a braking function. The descent speed can be manually controlled, allowing escapees to choose to stop halfway through the descent so they can enter the balcony or window of the floor below, thus facilitating their escape.

[0023] 7. The cooling component has a novel activation mechanism: the cooling component rotates synchronously with the rotating disk during the descent, reducing the cumbersome manual operation and enabling water to be sprayed on and around the protective suit, which helps to lower the temperature around the escapee and thus increases the chances of survival.

The water storage box 29 is fixedly arranged on the inner wall of the rear side of the shell 15 and symmetrically arranged on the left and right sides of the top of the box body 17. The squeezing cylinder 30 is arranged through the circumferential inner wall of the box body 17 and located at the top of the box body 17.

[0042] As Figures 8-10As shown, the brake assembly 23 is symmetrically distributed on both sides of the rotating disc 20, and the push-pull device 42 is arranged between the brake assemblies 23. The brake assembly 23 comprises a swing arm 43, a connecting arm 44, a control arm 45, an operation handle 46, a sector gear 47 and a brake disc 48. The sector gear 47 is rotatably arranged on the inner wall of the rear side of the box body 17 and located below the rotating disc 20. An opening 49 is arranged on the bottom of the box body 17. One end of the swing arm 43 is fixedly arranged on the sector gear 47, and the brake disc 48 is fixedly arranged on the other end of the swing arm 43. One end of the connecting arm 44 is fixedly arranged on the swing arm 43. The control arm 45 is rotatably arranged on the inner wall of the rear side of the shell 15. One end of the control arm 45 is hingedly connected to the other end of the connecting arm 44 after passing through the opening 49.

The operation handle 46 is fixedly arranged on the end of the control arm 45 passing through the operation openings 50. The sector gears 47 on the brake assembly 23 are engaged. By pressing the operation handle 46 downward, the control arm 45 is driven to rotate, thereby driving the connecting arm 44 and the swing arm 43 to rotate, and driving the brake disc 48 to contact the circumferential side wall of the rotating disc 20 to generate friction, thereby limiting the rotation of the rotating disc 20, so that the rotating disc 20 can be braked at any time. Through the engagement of the two sets of sector gears 47, the two sets of brake assemblies 23 can work simultaneously, so that the escapee can choose to stop at the halfway to enter the balcony or window of the lower floor during the descending process, and the user can complete the escape conveniently.

[0043] As shown in the drawings, Figures 8-9 The push-pull device 42 comprises a sleeve 51, a pull rod 52 and a spring 53. The pull rod 52 slidably penetrates the inner walls on the upper and lower sides of the sleeve 51. The pull rod 52 is provided with a sliding block 54 on one end located in the sleeve 51, and the sliding block 54 is slidably arranged in the sleeve 51. The spring 53 is located in the sleeve 51 and between the two sliding blocks 54. One end of the pull rod 52 located outside the sleeve 51 is hingedly connected to one end of the swing arm 43 away from the sector gear 47. The sleeve 51 is located in front of the rotating disc 20. Initially, the spring 53 is in a compressed state, and the brake disc 48 is close to the rotating disc 20. When the operation handle 46 is pressed downward, the brake disc 48 contacts the circumferential side wall of the rotating disc 20 at this time. At this time, the spring 53 is continuously compressed. When the operation handle 46 is released, the spring 53 rebounds, the sliding blocks 54 move to both sides, the pull rod 52 moves to both sides, and the brake disc 48 is separated from the circumferential side wall of the rotating disc 20.

[0044] As shown in the drawings, Figures 1-2 , Figure 5As shown, the mounting plate 16 and the rear side wall of the shell 15 are provided with two sets of guide rollers 55, the rope 21 extends upward after passing between the two sets of guide rollers 55, and the top end of the rope 21 is provided with a fixing member 56. The arrangement of the guide rollers 55 allows the rope 21 to shuttle between the two guide rollers 55, so that the rope 21 slides smoothly, reducing the friction on the rope 21 and increasing the service life of the rope 21.

[0045] As shown in the drawings, Figures 1-2 The backpack body 2 is provided with a matching port one at the top for the rope 21 and the water spraying pipe 34 to pass through, and the backpack body 2 is provided with a matching port two at the left and right sides for the control arm 45 to pass through. The backpack body 2 wraps around the slow descent device body 3, and the backpack body 2 is integrally connected with the protective clothing body 1, which is convenient and fast to wear.

[0046] As shown in the drawings, Figure 6 The water storage box 29 is provided with a water inlet, and the water inlet is provided with a sealing cover 57.

[0047] As shown in the drawings, Figure 1 The left side of the sealing zipper 9 is sewn with a covering piece 10, the main magic tape 11 is fixed on the covering piece 10, the right side of the sealing zipper 9 is fixed with a secondary magic tape 12, and the main magic tape 11 and the secondary magic tape 12 are adhered to each other. Through the arrangement of the sealing zipper 9 and the covering piece 10, the external toxic gas can be effectively prevented from entering the protective clothing body 1.

[0048] In specific use, first, open the sealing zipper 9, put the feet into the trousers 7 and put on the boot covers 8, put the hands through the sleeves of the upper garment 4 and put on the protective gloves 6, then put on the head cover 5, and then pull up the sealing zipper 9, fix the covering piece 10 through the main magic tape 11 and the secondary magic tape 12. The integrated protective clothing body 1 is convenient and fast to wear, saves the wearing time, and improves the escape probability; then hang the fixing member 56 on the hook installed in advance. When the escapee jumps from a high place, the rope 21 is continuously stretched out, the rope winding disc 22 around the rope 21 is continuously rotated, thereby driving the rotating rod 18 to rotate, and then driving the rotating disc 20 to rotate. The guide wheel one 28 rolls in the wave-shaped guide groove 26, and the guide wheel one 28 can reduce friction. Since the wave-shaped guide groove 26 is a wave-shaped groove, when the rotating disc 20 rotates, the wave-shaped guide groove 26 guides the guide wheel one 28 to move back and forth, thereby driving the piston rod of the damper 19 to move back and forth through the guide rod one 27. Due to the damping effect of the damper 19, the piston rod of the damper 19 moves at a reduced speed, thereby reducing the rotation speed of the rotating disc 20, achieving the purpose of slowly rotating the rotating disc 20, and preventing a sudden drop at the initial stage of descent, so that the user is not afraid.

[0049] When the rotating disc 20 rotates, the guide wheel two 38 also rolls in the wave-shaped guide groove 26, drives the push rod 32 to reciprocate through the guide rod two 37, thereby driving the piston 31 to reciprocate in the extrusion cylinder 30, so as to continuously suck the water in the water storage box 29 into the extrusion cylinder 30 through the water suction pipe 33, and then sprayed out through the water spraying pipe 34, the connecting pipe 40, the annular pipe 35 and the spray head 36, sprayed on the protective clothing body 1 and around the protective clothing body 1, which is conducive to reducing the temperature around the escape personnel, thereby increasing the survival probability of the escape personnel;

[0050] Since the control arm 45 is bent and connected with the rear inner wall of the shell 15 through the rotating shaft at the bent position, when the operation handle 46 is pressed downward, the one end of the control arm 45 is driven to move downward, so that the end of the control arm 45 hinged with the connecting arm 44 is lifted up, thereby driving the end of the connecting arm 44 hinged with the control arm 45 to also lift up, thereby driving the swing arm 43 to rotate, thereby driving the brake disc 48 to contact with the circumferential side wall of the rotating disc 20 to generate friction, so as to limit the rotation of the rotating disc 20, thereby being able to slow down and brake the rotating disc 20 at any time, and through the meshing of the two groups of sector gears 47, the two groups of brake assemblies 23 can work at the same time, so that the escape personnel can autonomously choose to stop in the middle of the way to enter the balcony or window of the lower floor, thereby facilitating the user to complete the escape.
