Description

Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to an airtight detection device for an integrated fire-fighting device. Background Art

[0002] The technical background of fire-fighting devices is closely related to the development of human society and the need for fire prevention and response. With the progress of society and the increasing complexity of building structures, the danger and destructiveness of fires have been continuously increasing. The Industrial Revolution brought a huge leap in productivity, but also further increased the risk of fires. The emergence of places such as factories and warehouses has prompted people to explore and research more effective fire-fighting means. In the 19th century, the invention of the steam engine provided power for the development of fire pumps, enabling fire-fighting water to be transported to the fire scene more efficiently. At the same time, the development of chemical technology has also created conditions for the innovation of fire extinguishing agents, and new fire extinguishing materials such as foam fire extinguishing agents have emerged.

[0003] An airtight detection device for fire-fighting devices is an important tool for detecting the sealing performance of fire-fighting equipment (such as fire extinguishers, gas cylinders, fire hydrants, etc.). Its working principle is usually to fill a certain pressure of gas into the interior of the fire-fighting device to be detected, and then monitor the change of pressure over a period of time to determine whether there is leakage. The advantage of this detection device is that it can timely detect the sealing problems of fire-fighting devices, ensure their normal operation at critical moments, and effectively play the role of fire extinguishing or rescue. In terms of structure, it generally includes a gas source supply part (such as an air compressor or a high-pressure gas cylinder), a pressure regulation and control unit, a detection cavity, a pressure sensor, a data acquisition and processing system, and a display and alarm unit, etc.

[0004] The existing airtight detection devices for fire-fighting equipment have many deficiencies in terms of operation. Its operation process is relatively complex and cumbersome.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0030] Refer to Figure 1 and Figure 3, an embodiment provided by the present utility model: an integrated airtight detection device for a fire-fighting device, comprising an equipment box 1 and an equipment seat 16. Four corners of the bottom end of the equipment box 1 are rotatably connected to universal columns 2. The outer bottom of the universal column 2 is rotatably connected to a wheel axle 4. The middle of the outer side of the wheel axle 4 is rotatably connected to a roller 3. The middle part of the inner side of the equipment box 1 is fixedly connected to an equipment rack 8. The middle part of the rear of the top end of the equipment rack 8 is fixedly connected to a compression air pump 7. The top of the rear end of the equipment box 1 is fixedly connected to a handle 5. The top of the compression air pump 7 is fixedly connected to an air delivery pipe 9. The other end of the air delivery pipe 9 is fixedly connected to a threaded connector 10. The fire-fighting detector pushes the equipment box 1 through the handle 5, causing the universal columns 2 at the bottom of the equipment box 1 to drive the rollers 3 to move to the fire-fighting pipeline. Then, the detector takes out the air delivery pipe 9 on the compression air pump 7 and threadedly connects the threaded connector 10 on the air delivery pipe 9 to a threaded seat 11.

[0031] Refer to Figure 1 - Figure 2 , the middle part of the rear end of the equipment seat 16 is fixedly connected to a threaded seat 11. The rear end of the threaded seat 11 is fixedly connected to the equipment seat 16. The front part of the inner side of the threaded seat 11 is fixedly connected to a fixed seat 14. The middle part of the inner side of the fixed seat 14 is slidably connected to a moving rod 28. The middle part of the rear end of the moving rod 28 is fixedly connected to a spring seat 12. A return spring 13 is sleeved on the rear part of the outer side of the moving rod 28. The middle part of the front end of the moving rod 28 is fixedly connected to a piston 15. The middle part of the rear of the top end of the equipment seat 16 is fixedly connected to an observation seat 17. The inner side of the observation seat 17 is threadedly connected to an observation tube 18. An air-operated ball 19 is arranged inside the observation tube 18. The middle part of the front end of the equipment seat 16 is fixedly connected to a connecting pipe 22. The front end of the outer side of the connecting pipe 22 is rotatably connected to a fire-fighting buckle 23. The fire-fighting detector holds the equipment seat 16 and docks the connecting pipe 22 on the equipment seat 16 to the fire-fighting interface. Subsequently, the detector starts the compression air pump 7 and pumps the compressed gas into the equipment seat 16. The spring seat 12 on the moving rod 28 drives the piston 15 to seal the air inlet hole under the push of the return spring 13, and keeps the fire-fighting pipeline under pressure for a certain period of time. During this period, observe whether the height of the air-operated ball 19 in the observation tube 18 changes to judge whether the airtightness of the fire-fighting pipeline meets the standard.

[0032] Refer to Figure 1 - Figure 3, on both the left and right sides at the bottom front end of the equipment box 1, there are fixedly connected radiators 27. At the top of the left and right ends of the equipment box 1, there are rotatably connected box covers 6. In the front middle part at the top end of the equipment seat 16, there is fixedly connected an instrument seat 20. Inside the instrument seat 20, there is a pressure gauge 21 connected by threads. On both the left and right ends outside the fire buckle 23, there are fixedly connected fixing claws 24. On both the upper and lower ends outside the fire buckle 23, there are provided fixing slots 26. At the front end of the connecting pipe 22, there is a sealing gasket 25. By turning the fire buckle 23 on the connecting pipe 22, the fixing claws 24 on the fire buckle 23 are connected to the fixing slots 26 on the fire interface, and then it is transported into the fire pipeline. Observe the pressure value on the pressure gauge 21. When the appropriate pressure value is reached, turn off the compressed air pump 7 and keep the fire pipeline under pressure.

[0033] Working principle: The fire detection personnel push the equipment box 1 through the handle 5, causing the universal columns 2 at the bottom of the equipment box 1 to drive the rollers 3 to move to the fire pipeline. Then, the fire detection personnel hold the equipment seat 16 and dock the connecting pipe 22 on the equipment seat 16 to the fire interface. Subsequently, by turning the fire buckle 23 on the connecting pipe 22, the fixing claws 24 on the fire buckle 23 are connected to the fixing slots 26 on the fire interface. Then, the detection personnel take out the air delivery pipe 9 on the compressed air pump 7 and thread the threaded connector 10 on the air delivery pipe 9 with the threaded seat 11. Subsequently, the detection personnel start the compressed air pump 7, pump the compressed gas into the equipment seat 16 and then into the fire pipeline. Observe the pressure value on the pressure gauge 21. When the appropriate pressure value is reached, turn off the compressed air pump 7. The spring seat 12 on the moving rod 28 drives the piston 15 to seal the air inlet hole under the push of the return spring 13, and keep the fire pipeline under pressure for a certain period of time. During this period, observe whether the height of the pneumatic ball 19 in the observation pipe 18 changes to judge whether the air tightness of the fire pipeline meets the standard.
