Technical Field
[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a pipeline-type heptafluoropropane gas fire extinguishing device. Background Technology
[0002] With the development of modern industry and technology, the demand for fire safety in various places is increasing. Traditional fire extinguishing methods, such as water spraying and foam extinguishing, may not be able to meet the needs of rapid, effective and residue-free fire extinguishing in certain specific situations. Therefore, gas extinguishing technology has emerged, among which heptafluoropropane extinguishing technology is favored due to its high efficiency, environmental protection and safety characteristics.
[0003] Existing piped heptafluoropropane gas fire extinguishing devices are cumbersome to replace with heptafluoropropane storage cylinders and require professional personnel to operate, increasing maintenance and time costs. In addition, some equipment requires specific tools during disassembly and assembly, increasing the complexity of disassembly and assembly. To solve the above problems, this utility model provides a piped heptafluoropropane gas fire extinguishing device. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pipeline-type heptafluoropropane gas fire extinguishing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pipeline-type heptafluoropropane gas fire extinguishing device includes a storage tank. A partition plate is fixedly connected to the middle of the interior of the storage tank. Support plates are fixedly connected to both sides of the interior of the storage tank. A fixing clamping ring is fixedly connected to one side of the upper surface of the support plate, and a clamping assembly is fixedly connected to the other side of the upper surface of the support plate. A heptafluoropropane storage bottle is provided on the upper surface of the support plate. A connection port is fixedly connected to the upper end of the heptafluoropropane storage bottle. A connection assembly is provided on the upper surface of the storage tank. Protective doors are hinged to both sides of the front of the storage tank.
[0007] As a further improvement of this utility model, the clamping assembly includes a mounting plate fixedly connected to the other side of the upper surface of the support plate. A threaded hole is provided on one side of the mounting plate, and an adjusting bolt adapted to the threaded hole is threadedly connected to one side of the mounting plate. A bearing is rotatably connected to one end of the adjusting bolt, a movable clamping ring is fixedly connected to one side of the bearing, and a handle is fixedly connected to the other end of the adjusting bolt.
[0008] As a further improvement of this utility model, a limiting groove is provided at the upper and lower ends of one side of the mounting plate. Two limiting rods that are adapted to the limiting groove are fixedly connected to the side of the movable clamping ring opposite to the limiting groove. Rubber pads are fixedly connected to the inner walls of both the fixed clamping ring and the movable clamping ring.
[0009] As a further improvement of this utility model, the connecting assembly includes several mounting rings fixedly connected to the upper surface of the storage box. The same connecting pipe is fixedly connected inside the several mounting rings. Two solenoid valves are provided at both ends of the surface of the connecting pipe. One-way valves are fixedly connected to both ends of the connecting pipe. Fire extinguishing pipes are fixedly connected to the opposite ends of the two one-way valves.
[0010] As a further improvement of this utility model, mounting grooves are provided on both sides of the upper surface of the storage box, and a high-pressure hose is fixedly connected inside the mounting groove. The lower end of the high-pressure hose is fixedly connected to the connection port, and the upper end of the high-pressure hose is fixedly connected to the connection pipe.
[0011] As a further improvement of this utility model, both of the protective doors are provided with visible glass at the top of their front sides.
[0012] The beneficial effects of this utility model are:
[0013] By incorporating a clamping assembly, during use, rotating the handle drives the adjusting bolt, which in turn moves the movable clamping ring. This design, combining the fixed and movable clamping rings with the adjustable bolt, allows the heptafluoropropane storage cylinder to be securely and flexibly mounted on the support plate. This not only ensures the stability of the storage cylinder within the system but also facilitates quick and easy securing and release of the cylinder, reducing cylinder replacement time and ensuring the continued effectiveness of the fire extinguishing system.
[0014] By setting a limiting rod, the moving clamping ring can drive the limiting rod to move simultaneously during use. The sliding of the limiting rod in the limiting groove effectively prevents the clamping ring from shifting or shaking, thus ensuring the stability and accuracy of the clamping process. At the same time, the rubber pad on the inner wall of the clamping ring not only increases friction and prevents the storage bottle from slipping, but also reduces damage to the surface of the storage bottle during clamping to a certain extent, extending its service life.
[0015] By setting up connection components, the device can quickly deliver heptafluoropropane gas into the fire extinguishing pipeline through the automatic opening of the solenoid valve when a fire occurs. This reduces the time for human intervention, improves the timeliness of fire extinguishing, helps to quickly control the fire, and reduces the losses caused by the fire. In addition, the one-way valve design prevents gas backflow, further enhancing the reliability and safety of the system.
[0016] In summary, the device of this utility model has a simple structure, is easy to operate, and is simple and quick to maintain and repair, thus reducing maintenance costs. It is suitable for various places that require gas extinguishing and shows significant beneficial effects in terms of fixing mechanism, clamping performance, extinguishing response, operation design and application prospects.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-4 A pipeline-type heptafluoropropane gas fire extinguishing device includes a storage tank 1. A partition plate 2 is fixedly connected to the middle of the interior of the storage tank 1. Support plates 3 are fixedly connected to both sides of the interior of the storage tank 1. A fixing clamping ring 4 is fixedly connected to one side of the upper surface of the support plate 3. A clamping assembly is fixedly connected to the other side of the upper surface of the support plate 3. A heptafluoropropane storage bottle 5 is provided on the upper surface of the support plate 3. A connection port 6 is fixedly connected to the upper end of the heptafluoropropane storage bottle 5. A connection assembly is provided on the upper surface of the storage tank 1. Protective doors 7 are hinged to both sides of the front of the storage tank 1.
[0024] In this invention, the clamping assembly includes a mounting plate 8 fixedly connected to the other side of the upper surface of the support plate 3. A threaded hole 9 is provided on one side of the mounting plate 8, and an adjusting bolt 10 adapted to the threaded hole 9 is threadedly connected to one side of the mounting plate 8. A bearing 11 is rotatably connected to one end of the adjusting bolt 10, and a movable clamping ring 12 is fixedly connected to one side of the bearing 11. A handle 13 is fixedly connected to the other end of the adjusting bolt 10. The handle 13 drives the adjusting bolt 10 to rotate, and the rotation of the adjusting bolt 10 causes the movable clamping ring 12 to move on the mounting plate 8 until the movable clamping ring 12 and the fixed clamping ring 4 secure the heptafluoropropane storage bottle 5. The mounting plate 8 has limit grooves 14 at both the upper and lower ends on one side. The movable clamping ring 12 is fixedly connected to two limit rods 15 that are adapted to the limit grooves 14 on the opposite side of the limit grooves 14. When the movable clamping ring 12 moves, it drives the limit rods 15 to move within the limit grooves 14, thereby making the movement of the movable clamping ring 12 more stable. The inner walls of the fixed clamping ring 4 and the movable clamping ring 12 are fixedly connected with rubber pads 16. The rubber pads 16 not only increase the friction and prevent the heptafluoropropane storage bottle 5 from slipping, but also reduce the damage to the surface of the heptafluoropropane storage bottle 5 during clamping to a certain extent, thus extending its service life.
[0025] The connection assembly includes several mounting rings 17 fixedly connected to the upper surface of the storage tank 1. The same connecting pipe 18 is fixedly connected inside the mounting rings 17. Two solenoid valves 19 are provided at both ends of the surface of the connecting pipe 18. One-way valves 20 are fixedly connected to both ends of the connecting pipe 18. Fire extinguishing pipes 21 are fixedly connected to the opposite ends of the two one-way valves 20. The one-way valves 20 prevent gas backflow and enhance the safety and reliability of the system.
[0026] The storage box 1 has mounting slots 22 on both sides of its upper surface. A high-pressure hose 23 is fixedly connected inside the mounting slot 22. The lower end of the high-pressure hose 23 is fixedly connected to the connection port 6, and the upper end of the high-pressure hose 23 is fixedly connected to the connecting pipe 18. The high-pressure hose 23 makes the device more stable during operation. The upper front of the two protective doors 7 is equipped with a viewing glass 24.
[0027] In use, the heptafluoropropane storage bottle 5 is first placed between the fixed clamping ring 4 and the movable clamping ring 12 on the support plate 3. The adjusting bolt 10 is rotated by the handle 13. As the adjusting bolt 10 rotates, the movable clamping ring 12 moves on the mounting plate 8 until it is secured by the fixed clamping ring 4 and the movable clamping ring 12. Simultaneously, the movement of the movable clamping ring 12 causes the limiting rod 15 to move within the limiting groove 14, thus ensuring more stable movement of the movable clamping ring 12. The rubber pads 16 on the inner walls of the movable clamping ring 12 and the fixed clamping ring 4 can also more securely clamp the heptafluoropropane storage bottle 5. Then, the high-pressure hose 23 is connected to the connection port 6 of the heptafluoropropane storage bottle 5. After installation, the protective door 7 is closed. In case of fire, the solenoid valve 19 on the connecting pipe 18 in the corresponding direction will automatically open. Heptafluoropropane enters the connecting pipe 18 through the high-pressure hose 23, and finally enters the fire extinguishing pipe 21 through the solenoid valve 19 and the one-way valve 20 in the corresponding direction of the fire to extinguish the fire.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
