Description

Technical Field

[0001] This application relates to the technical field of fire-fighting equipment, and in particular to a pneumatic crushing device for an externally pressurized heptafluoropropane fire extinguishing system. Background Technology

[0002] Heptafluoropropane fire extinguishing systems are high-efficiency fire extinguishing devices. Their extinguishing agent, HFC-ea, is a colorless, odorless, low-toxicity, highly insulating gas that does not cause secondary pollution, making it beneficial for extinguishing fires.

[0003] Heptafluoropropane fire extinguishing systems are mainly suitable for computer rooms, communication rooms, power distribution rooms, oil-immersed transformers, standby generator rooms, libraries, archives, museums, and document and cultural relic databases. They can be used to extinguish electrical fires, liquid fires, or fires involving fusible solids, solid surface fires, and gas fires where the gas supply can be cut off before extinguishing.

[0004] However, when using a heptafluoropropane fire extinguishing system to extinguish a fire, the firing pin in the pipeline is prone to deflection under the spray of heptafluoropropane when it is stored externally for a long time, resulting in diaphragm residue clogging the nozzle. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, one objective of this application is to provide a pneumatic breaking device for the extinguishing agent in an externally pressurized heptafluoropropane fire extinguishing system. When using heptafluoropropane to extinguish a fire, a pump can use nitrogen from the second pressurized tank to move the heptafluoropropane in the first pressurized tank within the spray pipe. Under the action of several spiral plates on the limiting block, the striking pin can rotate on the ring of the limiting ring and approach the balance diaphragm. When the pump is not working, the spring's elasticity causes the striking pin to automatically retract after breaking the diaphragm. The rotating striking pin pierces the balance diaphragm, preventing fragments from splashing and ensuring the smooth flow of the extinguishing agent.

[0007] To achieve the above objectives, the first aspect of this application provides a pneumatic breaking device for an externally pressurized heptafluoropropane fire extinguishing system, comprising a fixed plate for storing heptafluoropropane, a support plate for storing nitrogen gas disposed on the right side of the fixed plate, a spray pipe for fire extinguishing connected between the fixed plate and the support plate, and a breaking device for breaking the extinguishing agent disposed within the spray pipe; a groove is formed in the cavity of the spray pipe; the breaking device includes a balancing membrane assembly disposed within the groove for restricting the spray pipe, a breaking component for puncturing the balancing membrane assembly disposed on the right side of the balancing membrane assembly, and a support component for restricting the breaking component fixedly installed within the cavity of the spray pipe.

[0008] In addition, the pneumatic crushing device for the extinguishing agent of the externally pressurized heptafluoropropane fire extinguishing system proposed in this application may also have the following additional technical features:

[0009] In one embodiment of this application, the spray pipe is provided with an air pump for spraying heptafluoropropane to extinguish fires, and the air pump is located on the left side of the groove.

[0010] In one embodiment of this application, a pressure storage tank for storing heptafluoropropane is fixedly installed on the top of the fixing plate, and there are three pressure storage tanks. The tank body of the pressure storage tank is provided with a buckle for fixing the pressure storage tank, and a connecting pipe for connecting to the spray pipe is fixedly installed on the top of the pressure storage tank.

[0011] In one embodiment of this application, a second pressure tank for storing nitrogen is fixedly installed at the top of the support plate, and a second connecting pipe for connecting to the spray pipe is provided at the top of the second pressure tank.

[0012] In one embodiment of this application, the balancing membrane assembly includes a fixing frame embedded in a groove, and a balancing membrane is disposed on the frame of the fixing frame.

[0013] In one embodiment of this application, the breaking component includes a striking pin disposed on the right side of the balancing diaphragm for puncturing the balancing diaphragm, and the striking pin penetrates the support component. A limiting block for restricting the striking pin is fixedly installed at the right end of the striking pin.

[0014] In one embodiment of this application, a spiral plate for assisting the rotation of the firing pin is fixedly installed on the block of the limiting block, and there are several spiral plates. A spring is fitted on the rod of the firing pin, and the spring is located on the right side of the support assembly.

[0015] In one embodiment of this application, the support assembly includes a limiting ring fitted onto the firing pin, and three support bars are fixedly installed on the ring body for supporting the limiting ring.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] By incorporating an air pump and a rupture device, when using heptafluoropropane to extinguish a fire, the air pump can use nitrogen from the second pressurized tank to move the heptafluoropropane in the first pressurized tank within the spray pipe. Under the action of several spiral plates on the limiting block, the striking pin can rotate on the ring of the limiting ring and approach the balance diaphragm. When the air pump is not working, the spring elasticity allows the striking pin to automatically retract after the diaphragm is ruptured. The rotating striking pin pierces the balance diaphragm, preventing fragments from splashing and ensuring the smooth flow of extinguishing agent.

Detailed Implementation

[0026] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0027] The following description, in conjunction with the accompanying drawings, describes a pneumatically broken extinguishing agent device for an externally pressurized heptafluoropropane fire extinguishing system according to an embodiment of this application.

[0028] like Figures 1-5 As shown in the embodiment of this application, the pneumatic breaking device for the extinguishing agent of the externally pressurized heptafluoropropane fire extinguishing system may include a fixed plate 100 for storing heptafluoropropane, a support plate 200 for storing nitrogen gas on the right side of the fixed plate 100, a spray pipe 300 for fire extinguishing connected between the fixed plate 100 and the support plate 200, and a breaking device 400 for breaking the extinguishing agent disposed within the spray pipe 300; a groove 302 is formed in the cavity of the spray pipe 300; the breaking device 400 includes a balancing membrane assembly 430 disposed within the groove 302 for restricting the spray pipe 300, and a breaking component 410 for puncturing the balancing membrane assembly 430 on the right side of the balancing membrane assembly 430; the spray pipe 300... A support assembly 420 for restricting the rupture component 410 is fixedly installed inside the pipe. Therefore, when using heptafluoropropane to extinguish a fire, the nitrogen gas in the second pressure tank 201 can drive the heptafluoropropane in the first pressure tank 101 to move within the spray pipe 300. Under the action of several spiral plates 414 on the limiting block 413, the striking pin 411 can rotate on the ring of the limiting ring 421 and approach the balance diaphragm 432. When the air pump 301 is not working, the striking pin 411 will automatically retract after the diaphragm is broken by the elastic action of the spring 412. The striking pin 411 rotates and pierces the balance diaphragm 432, preventing fragments of the balance diaphragm 432 from splashing and ensuring the smooth flow of extinguishing agent.

[0029] Example 2

[0030] Reference manual attached Figure 2 It can be seen that the difference between Embodiment 2 and the implementation is that: a pressure storage tank 101 for storing heptafluoropropane is fixedly installed on the top of the fixing plate 100, and there are three pressure storage tanks 101, which are arranged in a linear array on the top of the fixing plate 100; the tank body of the pressure storage tank 101 is provided with a buckle 102 for fixing the pressure storage tank 101, and there are three buckles 102, which are arranged in a linear array and welded to the fixing frame on the fixing plate 100. The buckle 102 uses two semi-ring buckles to clamp the pressure storage tank 101, and the pressure storage tank 101 can be fixed by bolts and the two semi-ring buckles; a connecting pipe 103 for connecting to the spray pipe 300 is fixedly installed on the top of the pressure storage tank 101; the connecting pipe 103 can be connected to the pressure storage tank 101 by threaded connection, so the pressure storage tank 101 can be replaced.

[0031] In one embodiment of this application, such as Figure 2As shown, a second pressure tank 201 for storing nitrogen is fixedly installed on the top of the support plate 200. There are three pressure tanks 201, which are arranged in a linear array on the top of the support plate 200. The top of the pressure tank 201 is provided with a connecting pipe 202 for connecting to the spray pipe 300. Therefore, the nitrogen stored in the pressure tank 201 can be used to carry out the heptafluoropropane stored in the first pressure tank 101, and under the action of the spray pipe 300, the fire can be extinguished.

[0032] In one embodiment of this application, such as Figure 3 and Figure 4 As shown, the spray pipe 300 is equipped with an air pump 301 for spraying heptafluoropropane to extinguish fires, and the air pump 301 is located on the left side of the groove 302. The air pump 301 can be connected to the spray pipe 300 via bolts.

[0033] In one embodiment of this application, such as Figure 5 As shown, the balancing membrane assembly 430 includes a fixing frame 431 embedded in the groove 302, wherein the fixing frame 431 is made of rubber to facilitate the fixing frame 431 being snapped into the groove 302 in the spray pipe 300; a balancing membrane 432 is provided on the frame of the fixing frame 431; therefore, the balancing membrane 432 can be used to seal the spray pipe 300.

[0034] Furthermore, the breaking assembly 410 includes a striking pin 411 disposed on the right side of the balancing diaphragm 432 for puncturing the balancing diaphragm 432, and the striking pin 411 penetrates the support assembly 420, and the striking pin 411 is a tungsten steel needle; a limiting block 413 for limiting the striking pin 411 is fixedly installed at the right end of the striking pin 411.

[0035] Furthermore, a spiral plate 414 for assisting the rotation of the firing pin 411 is fixedly installed on the block of the limiting block 413, and there are several spiral plates 414, which are welded to the block of the limiting block 413 in a circumferential array; while several spiral plates 414 are welded to the block of the limiting block 413 at an angle; therefore, when the nitrogen gas in the second pressure tank 201 is driven by the air pump 301 to move the heptafluoropropane in the first pressure tank 101 within the spray pipe 300, the firing pin 411 can be rotated and approach the balance diaphragm 432 under the action of several spiral plates 414 on the limiting block 413, causing the balance diaphragm 432 to rotate and break; a spring 412 is fitted on the rod of the firing pin 411, and the spring 412 is located on the right side of the support assembly 420; when the air pump 301 is not working, the elastic action of the spring 412 will cause the firing pin 411 to automatically retract after the diaphragm breaks.

[0036] The support assembly 420 includes a limiting ring 421 fitted onto the firing pin 411, and the firing pin 411 can move left and right on the limiting ring 421; under the action of the limiting block 413, the firing pin 411 is prevented from falling off the limiting ring 421; support bars 422 for supporting the limiting ring 421 are fixedly installed on the ring body of the limiting ring 421, and there are three support bars 422; the three support bars 422 are welded in a circumferential array inside the cavity of the spray pipe 300; therefore, in the application of... When using heptafluoropropane to extinguish a fire, the nitrogen gas in the second pressure tank 201 can be used by the air pump 301 to move the heptafluoropropane in the first pressure tank 101 within the spray pipe 300. Under the action of several spiral plates 414 on the limiting block 413, the firing pin 411 can rotate on the ring of the limiting ring 421 and approach the balance diaphragm 432, so that the firing pin 411 can be automatically retracted after the diaphragm is broken. Therefore, it can prevent the balance diaphragm 432 from causing blockage of the spray pipe 300 after it is broken.

[0037] In summary, the pneumatic breaking device for the extinguishing agent in the externally pressurized heptafluoropropane fire extinguishing system of this application embodiment can, when using heptafluoropropane to extinguish a fire, use the air pump 301 to drive the heptafluoropropane in the pressure tank 101 to move within the spray pipe 300 by using nitrogen gas from the pressure tank 201. Under the action of several spiral plates 414 on the limiting block 413, the striking pin 411 can rotate on the ring of the limiting ring 421 and approach the balance diaphragm 432. When the air pump 301 is not working, the striking pin 411 automatically retracts after the diaphragm is broken by the elastic action of the spring 412. The rotating striking pin 411 pierces the balance diaphragm 432, preventing fragments of the balance diaphragm 432 from splashing and ensuring the smooth flow of the extinguishing agent.
