Description

Technical Field

[0001] This application relates to the technical field of fire extinguisher inflation, and in particular to an inflation device for ultrafine dry powder fire extinguishers. Background Technology

[0002] Ultrafine dry powder fire extinguishers are highly efficient fire-fighting devices. Their extinguishing medium consists of extremely fine dry powder that quickly covers the burning surface, cutting off the contact between the burning material and oxygen, thus effectively extinguishing the fire. Compared to traditional fire extinguishers, ultrafine dry powder fire extinguishers extinguish fires faster, rapidly suppressing the fire source and reducing the possibility of fire spread. Furthermore, the extremely small particles of ultrafine dry powder can penetrate deep into the fire source, providing a wide coverage area, making them suitable for extinguishing fires in complex structures or hard-to-reach locations.

[0003] In related technologies, during the production and processing of ultrafine dry powder fire extinguishers, production personnel need to inflate the extinguisher with gas. During inflation, personnel need to connect the inflation nozzle (connected to the gas source) to the inflation port on the ultrafine dry powder fire extinguisher, and then start the air pump to inject gas into the extinguisher through the inflation nozzle. However, during inflation, the connection between the inflation nozzle and the extinguisher may detach due to pressure fluctuations. Therefore, before inflation, operators need to repeatedly check the firmness of the connection. However, some fire extinguishers may have manufacturing defects in the inflation port, which may further increase the risk of detachment, and could even cause the extinguisher to be blown away by the pressure during inflation, potentially posing a safety threat to surrounding personnel and hindering practical use.

[0004] Therefore, those skilled in the art have provided an air-filling device for ultrafine dry powder fire extinguishers to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the issue raised in the background art that some fire extinguishers may have manufacturing defects in their inflation ports during production, which could cause the fire extinguisher to be blown away by air pressure during inflation, potentially posing a safety threat to surrounding personnel, this application provides an inflation device for ultrafine dry powder fire extinguishers.

[0006] The technical solution provided in this application for an air-charging device for ultrafine dry powder fire extinguishers is as follows:

[0007] An inflation device for an ultrafine dry powder fire extinguisher includes an explosion-proof box, inside which is placed a rack on which the ultrafine dry powder fire extinguisher body is placed. A limiting component is disposed inside the explosion-proof box and located at the top of the ultrafine dry powder fire extinguisher body. A hydraulic cylinder is fixedly disposed on the top of the inner wall of the explosion-proof box, and the output end of the hydraulic cylinder is fixedly connected to the upper surface of the limiting component for driving the limiting component to move up and down. An inflation component is disposed inside the explosion-proof box, and one end of the inflation component passes through the limiting component and is connected to the top of the ultrafine dry powder fire extinguisher body for inflating the ultrafine dry powder fire extinguisher body.

[0008] By adopting the above technical solution, the ultrafine dry powder fire extinguisher body is placed into the explosion-proof box for protection using a placement rack. The hydraulic cylinder is activated to control the lowering of the limiting component, causing one end of the inflation component to connect with the ultrafine dry powder fire extinguisher body. Activating the inflation component can inflate the ultrafine dry powder fire extinguisher body. During the inflation process, the placement rack and the limiting component work together to further limit and protect the ultrafine dry powder fire extinguisher body, thereby enhancing the safety of surrounding operators.

[0009] Preferably, the explosion-proof box includes a rectangular box, and the placement rack, the ultra-fine dry powder fire extinguisher body, the limiting component, the inflation component and the hydraulic cylinder are all located inside the rectangular box. A protective door is movably connected to one side of the rectangular box via a hinge. The protective door has an opening through which the protective door passes, and the interior of the opening is provided with explosion-proof glass.

[0010] By adopting the above technical solution, the inflation space can be isolated between the protective door and the rectangular box when the door is closed, and the viewing port, in conjunction with the explosion-proof glass, allows personnel to easily check the inflation status of the ultrafine dry powder fire extinguisher.

[0011] Preferably, the placement rack includes a rectangular block located inside the rectangular box, the upper surface of the rectangular block is provided with a placement groove, the bottom of the ultrafine dry powder fire extinguisher body is located inside the placement groove, and the side of the rectangular block near the protective door is provided with a push-pull groove.

[0012] By adopting the above technical solution, the placement groove can restrict the placement position of the ultrafine dry powder fire extinguisher body on the rectangular block, and the push-pull groove can facilitate the user to control the movement of the rectangular block.

[0013] Preferably, the limiting component includes a mounting plate fixedly connected to the output end of the hydraulic cylinder. Several springs are uniformly fixedly connected to the upper surface of the mounting plate, and limiting blocks are fixedly connected to the lower end faces of the springs. A limiting groove is provided on the limiting block to pass through the limiting block, and the top of the ultrafine dry powder fire extinguisher body is located inside the limiting groove.

[0014] By adopting the above technical solution, when the hydraulic cylinder is started, it can drive the limiting block to move downward through the cooperation of the mounting plate and several springs. When the limiting block moves downward, the body of the ultrafine dry powder fire extinguisher can be located inside the limiting groove. The limiting groove can restrict the placement position of the body of the ultrafine dry powder fire extinguisher. Furthermore, the continuous downward movement of the mounting plate can control one end of the inflation component to dock with the body of the ultrafine dry powder fire extinguisher.

[0015] Preferably, a sliding rod is fixedly connected to one side of the inner wall of the rectangular box, and a sliding groove is provided on one side of the rectangular block, with the sliding rod located inside the sliding groove.

[0016] By adopting the above technical solution, the stability of the rectangular block can be enhanced when it is moved by personnel pulling it, through the cooperation of the sliding rod and the sliding groove.

[0017] Preferably, the inflation assembly includes an inflation pump fixedly connected to one side of the inner wall of the rectangular box. One end of the inflation pump is fixedly connected to an air extraction pipe, and the end of the air extraction pipe away from the inflation pump passes through the rectangular box. The other end of the inflation pump is fixedly connected to an air supply pipe, and the end of the air supply pipe away from the inflation pump passes through the mounting plate and is fixedly connected to an inflation nozzle. The bottom end of the inflation nozzle is connected to the top end of the ultrafine dry powder fire extinguisher body.

[0018] By adopting the above technical solution, when the air pump is started, it can draw air from the air source through the air extraction pipe and then transport the gas to the air filling nozzle through the air delivery pipe. The gas can then be transported into the body of the ultra-fine dry powder fire extinguisher through the air filling nozzle.

[0019] Preferably, a number of guide rods are uniformly fixedly connected to the lower surface of the mounting plate, and a number of guide grooves are uniformly opened on the upper surface of the limiting block, with the bottom end of the guide rod located inside the guide groove.

[0020] By adopting the above technical solution, after the limiting block comes into contact with the body of the ultrafine dry powder fire extinguisher, the movement between the mounting plate and the limiting block can be guided by the cooperation of the guide rod and the guide groove.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. This inflation device for ultrafine dry powder fire extinguishers, through the set placement rack, allows the ultrafine dry powder fire extinguisher body to be placed into the explosion-proof box. Activating the hydraulic cylinder controls the downward movement of the limiting component, which controls one end of the inflation component to connect with the ultrafine dry powder fire extinguisher body. Activating the inflation component allows the ultrafine dry powder fire extinguisher body to be inflated. During the inflation process, the placement rack and limiting component work together to further limit and protect the ultrafine dry powder fire extinguisher body, thereby minimizing the possibility of the ultrafine dry powder fire extinguisher body being blown away by air pressure during inflation due to the connection between the inflation component and the ultrafine dry powder fire extinguisher body detaching. This enhances the safety of surrounding operators.

[0023] 2. The inflation device for ultrafine dry powder fire extinguishers features a protective door that isolates the inflation space from the rectangular box when closed. The viewing port, in conjunction with the explosion-proof glass, allows personnel to easily observe the inflation status of the ultrafine dry powder fire extinguisher. The placement slot restricts the placement position of the ultrafine dry powder fire extinguisher on the rectangular block. The push-pull slot facilitates the movement of the rectangular block by the user. When the user pulls the rectangular block, the sliding rod and sliding slot enhance the stability of the rectangular block during movement.

[0024] 3. The inflation device for ultrafine dry powder fire extinguishers is equipped with a hydraulic cylinder that, when activated, works with a mounting plate and several springs to move a limiting block downwards. As the limiting block moves downwards, the ultrafine dry powder fire extinguisher body is positioned inside a limiting groove. This limiting groove restricts the placement of the ultrafine dry powder fire extinguisher body. The continuous downward movement of the mounting plate controls the connection between one end of the inflation assembly and the ultrafine dry powder fire extinguisher body. A guide rod, in conjunction with a guide groove, guides the movement between the mounting plate and the limiting block. When the inflation pump is activated, it draws gas through an extraction pipe and then delivers the gas to the inflation nozzle through a delivery pipe. The inflation nozzle then delivers the gas into the ultrafine dry powder fire extinguisher body. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses an air-charging device for ultrafine dry powder fire extinguishers. (Refer to...) Figure 1 and Figure 2 An inflation device for an ultrafine dry powder fire extinguisher includes an explosion-proof box 1, a placement rack 2 inside the explosion-proof box 1, an ultrafine dry powder fire extinguisher body 3 placed on the placement rack 2, a limiting component 4 disposed inside the explosion-proof box 1 and located on top of the ultrafine dry powder fire extinguisher body 3, a hydraulic cylinder 6 fixedly disposed on the top of the inner wall of the explosion-proof box 1, the output end of the hydraulic cylinder 6 being fixedly connected to the upper surface of the limiting component 4 for driving the limiting component 4 to move up and down, and an inflation component 5 disposed inside the explosion-proof box 1, one end of the inflation component 5 penetrating the limiting component 4 and engaging with the top of the ultrafine dry powder fire extinguisher body 3 for inflation of the ultrafine dry powder fire extinguisher body 3.

[0032] In this embodiment, the explosion-proof box 1 in the inflation device for the ultra-fine dry powder fire extinguisher provides a dedicated space for inflation of the ultra-fine dry powder fire extinguisher body 3, thereby isolating the inflation process of the ultra-fine dry powder fire extinguisher body 3. A placement rack 2 is placed inside the explosion-proof box 1 to restrict the placement position of the ultra-fine dry powder fire extinguisher body 3 during inflation. Furthermore, a limiting component 4 is installed inside the explosion-proof box 1 via a hydraulic cylinder 6. After the user places the ultra-fine dry powder fire extinguisher body 3 into the explosion-proof box 1 via the placement rack 2, the hydraulic cylinder 6 can be activated to control the limiting component 4 to move downwards. After the limiting component 4 moves downwards, the ultra-fine dry powder fire extinguisher body 3 can be extinguished from above. The main body 3 is engaged and limited. While the limiting component 4 moves downward, it can control one end of the inflation component 5 to dock with the ultra-fine dry powder fire extinguisher body 3. The end of the inflation component 5 away from the ultra-fine dry powder fire extinguisher body 3 is directly connected to the gas source. Thus, by activating the inflation component 5, the ultra-fine dry powder fire extinguisher body 3 can be inflated. During the inflation process, the placement frame 2, in cooperation with the limiting component 4, can further limit and protect the ultra-fine dry powder fire extinguisher body 3. This can minimize the possibility of the ultra-fine dry powder fire extinguisher body 3 being blown away by air pressure during inflation due to the docking part of the inflation component 5 and the ultra-fine dry powder fire extinguisher body 3 detaching. This can enhance the safety of surrounding operators and make this application more conducive to practical use.

[0033] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the explosion-proof box 1 includes a rectangular box 101. The placement rack 2, the ultra-fine dry powder fire extinguisher body 3, the limiting component 4, the inflation component 5, and the hydraulic cylinder 6 are all located inside the rectangular box 101. A protective door 102 is movably connected to one side of the rectangular box 101 via a hinge. An inspection port 103 is provided on the protective door 102, and an explosion-proof glass 104 is installed inside the inspection port 103.

[0034] In this embodiment, the rectangular box 101 and the protective door 102 can be made of steel or aluminum alloy, which gives the rectangular box 101 and the protective door 102 good strength and toughness. This allows the inflation space to be isolated between the protective door 102 and the rectangular box 101 when the door is closed. The viewing port 103, in conjunction with the explosion-proof glass 104, allows personnel to easily check the inflation status of the ultrafine dry powder fire extinguisher body 3. The explosion-proof glass 104 can be made of laminated glass, tempered glass, or bulletproof glass, which can withstand high-energy impacts, thereby enhancing the protection of the explosion-proof box 1.

[0035] In a further preferred embodiment of this utility model, such as Figure 1, Figure 2 and Figure 3 As shown, the limiting component 4 includes a mounting plate 401 fixedly connected to the output end of the hydraulic cylinder 6. Several springs 402 are evenly fixedly connected to the upper surface of the mounting plate 401. Limiting blocks 403 are fixedly connected to the lower end faces of the several springs 402. A limiting groove 404 is provided on the limiting block 403 to pass through the limiting block 403. The top of the ultrafine dry powder fire extinguisher body 3 is located inside the limiting groove 404.

[0036] In this embodiment, when the hydraulic cylinder 6 is started, the mounting plate 401, in conjunction with several springs 402, can drive the limiting block 403 to move downward. When the limiting block 403 moves downward, the ultrafine dry powder fire extinguisher body 3 placed therein can be located inside the limiting groove 404. Thus, the limiting groove 404 can restrict the placement position of the ultrafine dry powder fire extinguisher body 3, which can enhance the stability of the position of the ultrafine dry powder fire extinguisher body 3 when it is being inflated. Furthermore, the continuous downward movement of the mounting plate 401 can control one end of the inflation component 5 to dock with the ultrafine dry powder fire extinguisher body 3. At the same time, it can also compress several springs 402 to contract. The elasticity of several springs 402 can enhance the limiting effect of the limiting block 403 on the ultrafine dry powder fire extinguisher body 3.

[0037] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the inflation assembly 5 includes an inflation pump 501 fixedly connected to one side of the inner wall of the rectangular box 101. One end of the inflation pump 501 is fixedly connected to an air extraction pipe 502. The end of the air extraction pipe 502 away from the inflation pump 501 passes through the rectangular box 101. The other end of the inflation pump 501 is fixedly connected to an air supply pipe 503. The end of the air supply pipe 503 away from the inflation pump 501 passes through the mounting plate 401 and is fixedly connected to an inflation nozzle 504. The bottom end of the inflation nozzle 504 is connected to the top end of the ultrafine dry powder fire extinguisher body 3.

[0038] In this embodiment, one end of the air extraction pipe 502 is connected to the gas source. When the air pump 501 is started, the air source can be extracted through the air extraction pipe 502 and then the gas can be transported to the air filling nozzle 504 through the air supply pipe 503. The gas can be transported into the interior of the ultra-fine dry powder fire extinguisher body 3 that is connected to it through the air filling nozzle 504.

[0039] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, several guide rods 7 are uniformly fixedly connected to the lower surface of the mounting plate 401, and several guide grooves 8 are uniformly opened on the upper surface of the limiting block 403, with the bottom end of the guide rod 7 located inside the guide groove 8.

[0040] In this embodiment, after the limiting block 403 contacts the body 3 of the ultrafine dry powder fire extinguisher, as the mounting plate 401 continues to move downward, the guide rod 7 and the guide groove 8 cooperate to guide the movement between the mounting plate 401 and the limiting block 403, thereby enhancing the stability of the position between the mounting plate 401 and the limiting block 403.

[0041] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the placement rack 2 includes a rectangular block 201 located inside the rectangular box 101. A placement groove 202 is provided on the upper surface of the rectangular block 201. The bottom of the ultrafine dry powder fire extinguisher body 3 is located inside the placement groove 202. A push-pull groove 203 is provided on the side of the rectangular block 201 near the protective door 102.

[0042] In this embodiment, the placement slot 202 restricts the placement position of the ultrafine dry powder fire extinguisher body 3 on the rectangular block 201, and the push-pull slot 203 facilitates the movement of the rectangular block 201 by the user, thereby making it easy for the user to place and pick up the ultrafine dry powder fire extinguisher body 3. In addition, a ball bearing is rolled at the bottom of the rectangular block 201, which reduces the friction between the rectangular block 201 and the bottom of the inner wall of the rectangular box 101 when the rectangular block 201 moves.

[0043] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, a sliding rod 9 is fixedly connected to one side of the inner wall of the rectangular box 101, and a sliding groove 10 is provided on one side of the rectangular block 201, with the sliding rod 9 located inside the sliding groove 10.

[0044] In this embodiment, when a user pulls the rectangular block 201 to move it, the sliding rod 9 and the sliding groove 10 cooperate to guide the movement of the rectangular block 201, thereby enhancing the stability of the rectangular block 201 during movement.

[0045] The implementation principle of an air-filling device for an ultrafine dry powder fire extinguisher according to an embodiment of this application is as follows:

[0046] In use, the ultra-fine dry powder fire extinguisher body 3, which needs to be inflated, is placed inside the explosion-proof box 1 via the placement rack 2. Activating the hydraulic cylinder 6 controls the lowering of the limiting component 4, which abuts and limits the ultra-fine dry powder fire extinguisher body 3 from above. Simultaneously, it controls one end of the inflation component 5 to connect with the ultra-fine dry powder fire extinguisher body 3. Activating the inflation component 5 inflates the ultra-fine dry powder fire extinguisher body 3. During inflation, the placement rack 2, in conjunction with the limiting component 4, provides further protection and limit on the ultra-fine dry powder fire extinguisher body 3, minimizing the risk of the fire extinguisher body 3 being blown away by air pressure due to the connection between the inflation component 5 and the ultra-fine dry powder fire extinguisher body 3. This enhances the safety of surrounding personnel and makes the application more practical.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
