Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher filling, and in particular to a filling device for water-based fire extinguishers. Background Technology

[0002] Water-based fire extinguishers, as a new type of environmentally friendly fire extinguisher, are filled with a water-based extinguishing agent containing flame retardants, surfactants, and other additives. They feature high extinguishing efficiency, environmental friendliness, non-toxicity, and excellent anti-reignition effects, effectively extinguishing Class A fires. The production of water-based fire extinguishers requires the use of filling equipment because it allows for precise control of the filling volume, ensuring each extinguisher meets the prescribed filling standards, guaranteeing consistent and reliable extinguishing performance; it improves production efficiency, meeting the needs of large-scale production; it ensures filling quality, guaranteeing the purity and uniformity of the extinguishing agent; and it possesses comprehensive safety protection devices, effectively preventing accidents and protecting the safety of production personnel and equipment.

[0003] Existing water-based fire extinguisher filling equipment is divided into fully automatic and semi-automatic types. Their working principles are generally similar. Fully automatic equipment first transports the bottles to be filled from the inlet to the filling station and positions them precisely via a chain conveyor. Then, it automatically extracts water, flame retardant, surfactant, and other components according to a preset formula ratio and mixes them in a mixing tank. The filling pump then accurately fills the extinguishing agent through the filling head according to the set amount and metering device. Subsequently, inert gases such as nitrogen are filled at the aeration station to reach the specified pressure. Finally, the bottle head valve or sealing cap is installed and sealed at the capping station. Semi-automatic equipment requires manual placement and positioning of the bottles. Manual assistance may be required during liquid preparation. Filling relies on manual control of time or observation of liquid level. Aeration and capping also involve more manual participation. Both types are based on the precise metering, mixing, filling, positioning, aeration, and capping of the extinguishing agent to efficiently and accurately produce water-based fire extinguishers that meet quality and performance standards.

[0004] In the current practical application scenarios of water-based fire extinguisher filling equipment, a significant problem urgently needs to be solved. Water-based fire extinguishers on the market come in various sizes and specifications, but the existing filling equipment lacks versatility. This leads to the need to frequently change to specialized equipment adapted to different sizes of fire extinguishers during filling operations. Each equipment change involves cumbersome processes such as equipment debugging, installation, and disassembly, consuming a lot of time and manpower, greatly reducing production efficiency, seriously affecting the efficient operation that water-based fire extinguisher filling equipment should have, and hindering the smooth progress of the entire production process. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-based fire extinguisher filling device, which aims to improve the problem of needing to use different devices to fill fire extinguishers of different sizes during the use of the equipment.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a water-based fire extinguisher filling device, including a filling machine, a liquid outlet pipe fixedly connected to one side of the filling machine, an operating component provided on one side of the filling machine, a fire extinguisher fixedly connected to one end of the liquid outlet pipe, a support plate slidably connected to the top of the fire extinguisher, multiple support columns fixedly connected to the bottom of the support plate, multiple sliding grooves opened inside the support plate, and multiple moving components provided inside the support plate;

[0007] Each of the moving components includes a sliding block, multiple sliding columns, and a fixing ring. The outer wall of each sliding block is slidably connected to the inside of the support plate. One end of each sliding column is fixedly connected to one side of the sliding block. The bottom of each fixing ring is fixedly connected to the top of the sliding block. One side of each sliding block is provided with a spring.

[0008] As a further description of the above technical solution:

[0009] The operating components include a pressure gauge and multiple buttons. One side of the pressure gauge is electrically connected to one side of the filling machine, and one side of each button is electrically connected to one side of the filling machine.

[0010] As a further description of the above technical solution:

[0011] An explosion-proof box is fixedly connected to the outer wall of the support plate, and a rotating shaft is rotatably connected to one side of the explosion-proof box.

[0012] As a further description of the above technical solution:

[0013] A box door is rotatably connected to the outer wall of the rotating shaft, and a handle is fixedly connected to one side of the box door.

[0014] As a further description of the above technical solution:

[0015] The explosion-proof box has multiple fixing blocks fixedly connected to one side, and each fixing block has multiple fixing pins slidably connected inside.

[0016] As a further description of the above technical solution:

[0017] Each of the fixed pins is fixedly connected to a limiting plate on its outer wall, and the outer wall of each limiting plate is slidably connected to the inside of the fixed block.

[0018] As a further description of the above technical solution:

[0019] Each of the fixed blocks is provided with multiple springs II inside, one end of each spring II is fixedly connected to the inside of the fixed block, and the other end of each spring II is fixedly connected to one end of the fixing pin.

[0020] As a further description of the above technical solution:

[0021] The fixing pins are arranged in a symmetrical array and slidably connected inside the fixing block, with one end of each fixing pin slidably connected inside the box door.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the fixing ring is first pulled outward, then the fire extinguisher is picked up and its bottom is placed on the top of the support plate. After that, the fixing ring is released so that it retracts inward under the action of the spring, so that the inner wall of the fixing ring fits against the outer wall of the fire extinguisher, thus fixing the fire extinguisher. This achieves the effect of filling fire extinguishers of different sizes during the use of the equipment, avoiding the problem of needing to use different equipment to fill fire extinguishers of different sizes during the use of the equipment, thereby improving the efficiency of a water-based fire extinguisher filling device.

[0024] 2. In this utility model, first, grasp the handle and pull it outward, causing the inner wall of the box door to press the fixing pin and retract into the fixing block, thereby unlocking the box door. Then, place the fire extinguisher into the explosion-proof box, and close the box door using the pivot, allowing the fixing block to enter the box door. When the fixing block enters the innermost part of the box door, the fixing pin pops out under the action of spring two. This achieves the effect of protecting the area around the fire extinguisher during equipment use, preventing excessive pressure from causing the fire extinguisher to explode and injure the operator. It avoids the problem of excessive internal pressure of the fire extinguisher causing it to explode and injure the surrounding operators during equipment use, thereby improving the practicality of a water-based fire extinguisher filling device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a water-based fire extinguisher filling device, including a filling machine 1. A liquid outlet pipe 4 is fixedly connected to one side of the filling machine 1 for discharging liquid. An operating component is provided on one side of the filling machine 1 for operating the filling machine 1. A fire extinguisher 5 is fixedly connected to one end of the liquid outlet pipe 4. The fire extinguisher 5 is the object to be filled. A support plate 6 is slidably connected to the top of the fire extinguisher 5 for supporting the fire extinguisher 5. Multiple support columns 7 are fixedly connected to the bottom of the support plate 6 for supporting the support plate 6. Multiple sliding grooves 8 are opened inside the support plate 6 for accommodating sliding columns 10. Multiple moving components are provided inside the support plate 6 for fixing the fire extinguisher 5.

[0034] Each moving component includes a sliding block 9, multiple sliding columns 10, a spring 11, and a retaining ring 12. The outer wall of each sliding block 9 is slidably connected to the inside of the support plate 6 to connect the retaining ring 12. One end of each sliding column 10 is fixedly connected to one side of the sliding block 9 to limit the movement range of the sliding block 9. The bottom of each retaining ring 12 is fixedly connected to the top of the sliding block 9 to fix the fire extinguisher 5. One side of each sliding block 9 is provided with a spring 11 to provide elastic force to the sliding block 9. One end of each spring 11 is fixedly connected to one side of the sliding block 9, and the other end of each spring 11 is fixedly connected to the inside of the support plate 6. The operating component includes a pressure gauge 2 and multiple buttons 3. One side of the pressure gauge 2 is electrically connected to one side of the filling machine 1 to display pressure data. One side of each button 3 is electrically connected to one side of the filling machine 1 to control the filling machine 1.

[0035] Specifically, when filling the water-based fire extinguisher 5, if it is necessary to fix the fire extinguisher 5, the operator first holds the fixing ring 12 and slowly pulls it outward. Then, the operator lifts the fire extinguisher 5 and places its bottom steadily on the top of the support plate 6. Immediately afterwards, the operator releases both hands, and the fixing ring 12 quickly contracts inward under the strong elastic force of the spring 11. Instantly, the inner wall of the fixing ring 12 fits tightly against the outer wall of the fire extinguisher 5. In this way, the fire extinguisher 5 is firmly fixed, preparing for the subsequent filling process.

[0036] Reference Figure 4 and Figure 5 An explosion-proof box 13 is fixedly connected to the outer wall of the support plate 6 to enclose the fire extinguisher 5 inside. A rotating shaft 14 is rotatably connected to one side of the explosion-proof box 13 for rotating the box door 15. The box door 15 is rotatably connected to the outer wall of the rotating shaft 14 for closing the explosion-proof box 13. A handle 16 is fixedly connected to one side of the box door 15 for pulling the box door 15. Multiple fixing blocks 17 are fixedly connected to one side of the explosion-proof box 13 for connecting the box door 15. Multiple fixing pins 18 are slidably connected inside each fixing block 17 for fixing the box door 15. The outer wall of each fixing pin 18... Each is fixedly connected to a limiting plate 19 to limit the movement range of the fixing pin 18. The outer wall of each limiting plate 19 is slidably connected to the inside of the fixing block 17. Each fixing block 17 is provided with multiple springs 20 to provide elastic force for the fixing pin 18. One end of each spring 20 is fixedly connected to the inside of the fixing block 17, and the other end of each spring 20 is fixedly connected to one end of the fixing pin 18. The fixing pins 18 are arranged in a symmetrical array and slidably connected to the inside of the fixing block 17. One end of each fixing pin 18 is slidably connected to the inside of the door 15.

[0037] Specifically, during the installation of fire extinguisher 5, before placing it into the explosion-proof box 13, the operator will first grasp the handle 16 and pull it outward slowly and firmly. With this action, the inner wall of the box door 15 contacts the fixing pin 18 and begins to compress it, causing the fixing pin 18 to retract into the fixing block 17. At the same time, the box door 15 is unlocked. Then, the operator picks up the fire extinguisher 5 and places it into the explosion-proof box 13. Subsequently, the operator holds the box door 15 with both hands and, with the help of the smooth rotation of the pivot 14, slowly closes the box door 15. During the closing process, the fixing block 17 slowly enters the box door 15. When the fixing block 17 reaches the innermost part of the box door 15, the spring 20 instantly activates, causing the fixing pin 18 to pop out and lock into the corresponding position. Thus, the explosion-proof box 13 is completely sealed, providing a solid guarantee for the safety of the fire extinguisher 5.

[0038] Working principle: When using the water-based fire extinguisher filling equipment, to secure the fire extinguisher 5, first grasp the handle 16 and pull it outwards, causing the inner wall of the cabinet door 15 to press against the fixing pin 18 and retract into the fixing block 17, thereby unlocking the cabinet door 15. Then, place the fire extinguisher 5 into the explosion-proof box 13, first pull the fixing ring 12 outwards, then pick up the fire extinguisher 5 and place its bottom on the top of the support plate 6. Afterwards, release the fixing ring 12 so that it retracts inwards under the action of the spring 11. The inner wall of the fixing ring 12 is brought into contact with the outer wall of the fire extinguisher 5 to fix the fire extinguisher 5. After the fire extinguisher 5 is fixed, the box door 15 is closed by the pivot 14, so that the fixing block 17 enters the box door 15. When the fixing block 17 enters the innermost part of the box door 15, the fixing pin 18 pops out under the action of the spring 20, thereby completing the sealing of the explosion-proof box 13. Then the liquid outlet pipe 4 is connected to the fire extinguisher 5. Finally, the filling machine 1 is started to start the filling work of the fire extinguisher 5.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
