Problems solved by technology

Therefore, a temperature-sensitive self-starting fire extinguishing device with a fixed fire extinguishing agent cylinder and a built-in siphon cannot be used in a micro-environment with multi-dimensional activities. For example, the wind power field requires an electric control cabinet that rotates at 2-3 latitudes
[0005] 2. Existing fire extinguishing devices are usually composed of detection elements, fire extinguishing agent storage containers, valve mechanisms, release pipelines or nozzles, etc., the structure is relatively complex, and the construction is also more complicated
It cannot be used when the operating environment is below 0°C

Embodiment 1

[0035] see figure 2 , this embodiment is applied to the protection of electrical control cabinets.

[0036] The external dimensions of the electrical control cabinet 6 are 2m(H)×1m(B)×0.5m(D), and there is no air exhaust port. After calculation, according to the requirements of the national standard, in order to achieve the effect of fire extinguishing, 0.7kg of FM200 (heptafluoropropane) gas needs to be injected into the cabinet within 10 seconds after the fire occurs, so as to achieve the effect of fully submerging the fire.

[0037] First, fill 0.7kg of FM200 (heptafluoropropane) fire extinguishing agent 4 and a fire detection tube type tubular temperature-sensing self-starting fire extinguishing device that drives nitrogen. The length is about 10 meters, and they are coiled around the electrical components in the cabinet. The distance between the pipes is 30cm~ About 40cm. The two ends of the device are placed in a high place inside the cabinet and in a position that is...

Embodiment 2

[0039] see image 3 , this embodiment is used to protect the 360-degree rotating frequency conversion electrical control cabinet.

[0040] The external dimensions of the frequency conversion electrical control cabinet 7 are 1.155m (H) × 0.59m (B) × 0.3m (D), IP65 protection level, and does not contain a discharge port. After calculation, according to the requirements of the national standard, in order to achieve the effect of fire extinguishing, it is necessary to inject 0.14kg of FM200 (heptafluoropropane) gas into the cabinet within 10 seconds after the fire occurs, so as to achieve the effect of completely submerging the fire.

[0041] First, fill 0.14kg of FM200 (heptafluoropropane) fire extinguishing agent 4 and the fire detection tube type tubular temperature-sensing self-starting fire extinguishing device that drives nitrogen, with a length of about 5 meters, coiled around the electrical components in the cabinet, and the pipe interval is 20cm to 30cm about. Combined ...

Abstract

The invention discloses a fire exploration pipe-type temperature-sensitive self-startup extinguishing device. The fire exploration pipe-type temperature-sensitive self-startup extinguishing device comprises a sealing container and a fire extinguishing agent sealed in the sealing container. The sealing container is prepared from a heat-sensitive material, the surface of the sealing container can be softened at a high temperature and be broken under the action of inner pressure so that a jet orifice is formed. The fire exploration pipe-type temperature-sensitive self-startup extinguishing device realizes combination of the exploration member, the extinguishing agent storage container and a conveying pipe. The exploration pipe is filled directly with the extinguishing agent and driving gas so that an extinguishing agent steel cylinder is avoided and the whole structure is simple and reliable, has a low failure rate, can be installed flexibly and conveniently and has a high cost performance.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire detection tube type temperature-sensing self-starting fire extinguishing device. Background technique [0002] In the field of fire protection, temperature-sensing self-starting fire extinguishing devices have always played an important role. With years of development, the domestic market basically has a fire-detecting tube-type temperature-sensing self-starting fire extinguishing device, a glass ball-type temperature-sensing self-starting fire extinguishing device and a fusible alloy temperature-sensing self-starting fire extinguishing device. [0003] But the existing temperature-sensing self-starting fire extinguishing device still has the following problems: [0004] 1. At present, the existing micro-environmental temperature-sensitive self-starting fire extinguishing devices require special storage containers (usually with built-in siphons), and most of them ...
