Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a safety fire fighting equipment for a power plant. Background Art

[0002] As an important hub of power supply, fire safety is of vital importance in power plants. There are many equipments in power plants. Once a fire occurs, the consequences will be disastrous. Therefore, power plants should be equipped with complete fire-fighting facilities, such as fire extinguishers, fire hydrants, etc., and regularly maintain and inspect them to ensure that they are in good condition.

[0003] In consideration of its high efficiency, rapid and accurate fire extinguishing capability, power plants generally use fire detection type fire extinguishing devices. Power plants have densely packed equipment and numerous power facilities. Once a fire occurs, the fire spreads quickly and traditional fire extinguishing methods may be difficult to quickly control. Fire detection type fire extinguishing devices can directly act on the fire source and quickly extinguish the flames in the early stages of the fire, effectively preventing the fire from spreading. However, the fire detection tube of the fire detection device is coiled and installed in the electrical equipment. However, because the fire detection tube needs to be coiled and installed, it may sometimes be limited by the internal structure of the electrical equipment, resulting in the detection effect at certain specific positions or angles not being as expected. In addition, if there is a more complex wiring or component layout inside the electrical equipment, it may also have a certain impact on the detection and fire extinguishing effect of the fire detection tube. Utility Model Content

[0004] The purpose of the utility model is to provide a power plant safety fire fighting equipment, which can effectively solve the problems in the background technology.

[0022] like Figure 1 As shown, the fire extinguisher 1 is fixedly installed on the outside of the protected equipment through fasteners, and the fire detection main pipe 3 passes through the outer shell of the protected equipment and is installed around the inside of the protected equipment;

[0023] like Figure 2-Figure 3 As shown, two limiting grooves 7 are provided on the outer side of the separation tube 5, and two sealing rings 8 are fixedly installed on one side of the two limiting grooves 7, and the inner cavity of the sealing ring 8 is connected with the inner cavity of the separation tube 5. By means of the setting of the limiting grooves 7 and the sealing rings 8, the angle adjustability of the fire detection auxiliary tube 6 can be guaranteed when the fire detection auxiliary tube 6 is connected to the separation tube 5. The separation tube 5 located between the two sealing rings 8 is provided with a plurality of medium flow grooves 9, and the two ends of the separation tube 5 are fixedly installed on the outer side of the fire detection main pipe 3 by welding, and the inner cavity of the separation tube 5 is connected with the inner cavity of the fire detection main pipe 3. By means of the medium flow grooves 9, the fire extinguishing medium can enter the fire detection auxiliary tube 6 through the medium flow grooves 9. A connecting pipe 10 is fixedly installed at the end, two limiting rings 12 are fixedly installed on the inner side of the connecting pipe 10, two sealing grooves 13 are provided on the connecting pipe 10 on one side of the limiting ring 12, two reinforcing ribs 11 are fixedly connected between the outer side of the fire detection auxiliary pipe 6 and the connecting pipe 10, the connecting pipe 10 is rotatably installed on the outer side of the separation pipe 5, and the limiting ring 12 is rotatably installed in the corresponding limiting groove 7, and the sealing groove 13 is rotatably installed on the outer side of the corresponding sealing ring 8, the connecting pipe 10 is rotatably installed on the outer side of the separation pipe 5 through the limiting ring 12 and the sealing groove 13, so that the sealing ring 8 expands in the sealing groove 13 after being subjected to the pressure of the fire extinguishing medium, thereby sealing the gap between the connecting pipe 10 and the separation pipe 5.

[0024] It should be noted that the utility model is a power plant safety fire fighting equipment. When in use, the fire extinguisher 1 can be first fixedly installed on the outer shell of the protected equipment through fasteners, and then, one end of the fire detection main pipe 3 is fixedly connected to the output end of the container valve 2, and then, the other end of the fire detection main pipe 3 is extended to the inside of the protected equipment through the outer shell of the protected equipment. Then, the fire detection main pipe 3 can be installed in the protected equipment with the help of fixings, and the pressure sensor 4 can be placed at the bottom of the protected equipment. Then, according to the actual structure inside the protected equipment, the corresponding fire detection auxiliary pipe 6 can be rotated on the outside of the corresponding separation pipe 5 with the connecting pipe 10 as the axis, that is, the limiting ring 12 on the inside of the connecting pipe 10 rotates in the limiting groove 7 on the outside of the separation pipe 5, which provides a limit and a certain sealing effect for the rotation of the connecting pipe 10, and the inside of the connecting pipe 10 and the outside of the separation pipe 5 have a certain friction resistance, so that When the fire detection auxiliary pipe 6 is able to rotate on the outside of the separation pipe 5 with the connecting pipe 10 as the axis, the rotation angle of the fire detection auxiliary pipe 6 can be fixed in real time.

At the same time, when the sealing ring 8 expands in the sealing groove 13, it can also connect and seal the connecting pipe 10 and the separation pipe 5 to prevent the fire extinguishing medium from flowing out from the gap between the connecting pipe 10 and the separation pipe 5.

[0025] When a fire occurs in the electrical equipment inside the protected device, the fire point may burn and rupture the fire detection main pipe 3 or the corresponding fire detection auxiliary pipe 6, so that the fire extinguishing medium in the fire extinguisher 1 is ejected from the ruptured fire detection main pipe 3 or the fire detection auxiliary pipe 6, thereby achieving the purpose of quickly extinguishing the fire point inside the protected equipment.
