Description

Technical Field

[0001] This utility model relates to the field of cable accessories technology, and in particular to a fire extinguishing device based on a cable joint. Background Technology

[0002] Due to the limited length of cables, there are always several joints in the middle of a power cable line. Only by connecting all the power cables can they work normally. The cable joint is a key component in the power system that connects two sections of cable. Its design, installation and maintenance directly affect the reliability and security of the power grid.

[0003] With the increase in electricity demand, the frequency of use of cable joints has gradually increased. However, due to factors such as aging of cable joints, improper installation, or external environmental influences, during the transmission of current in the wires, resistance will cause a certain amount of energy loss and heat generation. If there is a poor connection at the joint or the current at the connection point is too large, a high temperature effect will be generated, which may lead to a fire.

[0004] Therefore, this application provides a fire extinguishing device based on a cable connector to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to propose a fire extinguishing device based on a cable joint.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A fire extinguishing device based on a cable connector includes: an outer sheath, a mounting base, a connecting block, a flange seat, an installation pipe, a sealing plug, a limiting plate, a fire extinguishing agent storage bottle, a container valve, a nozzle, a temperature-sensitive glass bulb, a thermally sensitive connector, a stamped fire detection tube, and a pressure gauge. One end of the outer sheath is integrally provided with a connector. A mounting base is welded to the outer side of the outer sheath at the outer end of the connector. A connecting block is welded to the lower end of the outer sheath at the mounting base. A flange seat is welded to the end of the outer sheath away from the connector. An installation pipe is welded to the side of the outer sheath. A sealing plug is embedded in the opening of the installation pipe. A limiting plate is embedded in the other end of the installation pipe. A fire extinguishing agent storage bottle is welded to the other end of the limiting plate. A container valve is integrally provided at the lower end of the fire extinguishing agent storage bottle. A nozzle is provided at the end of the container valve. A temperature-sensitive glass bulb is embedded in the front end of the nozzle opening. A thermally sensitive connector is provided on the left side of the container valve. A stamped fire detection tube is installed at the end of the thermally sensitive connector. A pressure gauge is provided at the lower right end of the container valve.

[0008] Preferably, the outer sheath is a split design, consisting of two sets of outer shells joined together.

[0009] Preferably, the mounting base and the mating block are both welded to the two sets of outer shell joints of the outer sheath, and the mounting tube is located away from the joint of the outer shell and on the side of one set of outer shells.

[0010] Preferably, the mounting tube is provided in two sets, and the two sets of mounting tubes are horizontally welded to the side of the outer sheath, and the mounting tubes are connected to the outer sheath.

[0011] Preferably, the limiting plate is disc-shaped, fits snugly with the mounting pipe, and the diameter of the extinguishing agent storage bottle is larger than the diameter of the limiting plate.

[0012] Preferably, the extinguishing agent storage cylinder is installed laterally inside the outer sheath via a limiting plate.

[0013] Preferably, the stamped fire detection tube is adhered to the inner wall of the outer sheath by tape, and the stamped fire detection tube extends around the inner wall of the outer sheath to the joint and the flange seat respectively.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above scheme, an installation pipe is welded to the side of the outer sheath. Inside the installation pipe, a fire extinguishing agent storage bottle is installed via a limiting plate. The pressurized fire detection tube on the fire extinguishing agent storage bottle is attached to the inner wall of the outer sheath with tape. When the cable connected inside the cable joint catches fire, the pressurized fire detection tube softens and bursts at the point of highest temperature when it encounters fire. The pressure drop in the pressurized fire detection tube activates the container valve, and the dry powder in the fire extinguishing agent storage bottle is released through the release pipe to the nozzle to extinguish the fire. The dry powder fills the interior of the outer sheath, enabling the fire in the cable to be extinguished quickly. The fire is extinguished at its source, effectively suppressing the spread of the fire and reducing the losses caused by the cable fire.

[0016] In the above solution, by setting a stamped fire detection tube to be adhered to the inner wall of the outer sheath with tape, and extending the stamped fire detection tube around the inner wall of the outer sheath to the joint and flange seat respectively, the thermal sensing detection range of the stamped fire detection tube can be ensured to cover the outer end of the cable inside the outer sheath, increase the contact area with the ignition point, avoid dead angles, and make the detection more sensitive and faster.
