Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher detection, in particular to a non-pressure storage type perfluorohexanone fire extinguishing agent leakage detection device. Background Art

[0002] Traditional fire extinguishing systems often require a large pressure storage space and complex piping layout, which is undoubtedly a big challenge for the small, complex and hard-to-reach spaces in power facilities. The non-pressure storage perfluorohexanone fire extinguishing device cleverly avoids these problems. It uses pressure release technology to achieve rapid fire extinguishing without pressure storage.

[0003] Publication No. CN219757501U discloses a device for detecting the leakage of heptafluoropropane fire extinguishing agent. The patent detects that the weight of the heptafluoropropane fire extinguishing agent body is still decreasing through a gravity sensor, and then a buzzer sounds to remind people to perform emergency maintenance. This solves the problem in the prior art that the heptafluoropropane fire extinguisher has a partial leakage and the sensor is difficult to detect the gas leakage. However, the patent still has the following problems in actual use:

[0004] When the gravity sensor detects that the weight of the HFC-227ea fire extinguishing agent body is still decreasing, the buzzer sounds to remind people to perform emergency maintenance. However, in actual use, the working principle of the non-pressurized perfluorohexanone automatic fire extinguishing device is to use perfluorohexanone, a high-efficiency fire extinguishing agent, to quickly release it when a fire occurs to achieve the purpose of extinguishing the fire. This fire extinguishing mechanism extinguishes the fire through liquid, which is not convenient for detecting the leakage of the fire extinguishing mechanism. The leaked perfluorohexanone cannot be collected, which is easy to pollute the use environment. In addition, the perfluorohexanone fire extinguishing method is usually used in small spaces such as power cabinets. If the leakage is not collected, it is easy to affect the use of internal electrical components.

[0005] A non-pressure storage type perfluorohexanone fire extinguishing agent leakage detection device is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a non-pressure storage type perfluorohexanone fire extinguishing agent leakage detection device to solve the problem proposed in the above background technology that the weight of the heptafluoropropane fire extinguishing agent body is still decreasing when the gravity sensor is detected, and then the buzzer sounds to remind people to perform emergency maintenance.

The leaked perfluorohexanone cannot be collected, which is easy to pollute the use environment. In addition, the perfluorohexanone fire extinguishing method is usually used in narrow spaces such as power cabinets, and the leakage is not collected, which is easy to affect the use of internal electrical components.

Then the collecting bucket can be directly removed, so that the connecting plate leaves the rectangular sleeve, and the collecting bucket can be cleaned. Conversely, the collecting bucket can be installed and positioned, and the leaked liquid can be collected through the collecting assembly to avoid polluting the use environment and causing damage to other components, thereby improving practicality.
