The utility model discloses a realize above-mentioned purpose, realize through following technical scheme: an explosion-proof box for a cable joint comprises an upper cover and a lower cover spliced with the upper cover, wherein a magnetic absorption layer is arranged at the spliced part of the upper cover and the lower cover; the fire-retardant chamber of upper cover top portion being equipped with, fire-retardant intracavity is equipped with fire retardant storage jar, is equipped with the injection pipe on the fire retardant storage jar, is equipped with the shower nozzle in the upper cover, and the first end and the fire retardant storage jar intercommunication of injection pipe, the second end and the shower nozzle intercommunication of injection pipe are equipped with the solenoid valve on the injection pipe. The upper cover and the lower cover are fixed by magnetic attraction, so that the installation is convenient, and the glue can be directly filled and sealed after the attraction is in place. The upper cover is internally provided with the flame retardant, so that the flame retardant can be released when the ignition point of the internal cable appears, and the flame retardant property of the explosion-proof box is effectively improved.
Further, still be equipped with the main control unit in the fire-retardant intracavity, the main control unit includes control module, power module and wireless communication module, and control module is connected with power module, wireless communication module and solenoid valve respectively. The automatic control and remote data transmission of the electromagnetic valve are realized through the main control unit.
Furthermore, a temperature sensor is arranged in the upper cover, a humidity sensor is arranged in the lower cover, and the control module is connected with the temperature sensor and the humidity sensor respectively. The temperature and humidity monitoring of the inner part of the explosion-proof box after the installation is finished is realized, and the remote real-time monitoring of the running condition of the cable joint is realized through wireless transmission.
Furthermore, the top of the upper cover is provided with an energy release hole. When the cable middle joint is in short circuit breakdown or explosion, the impact force of explosion can be effectively reduced.
Furthermore, hydrophobic silica gel sealing layers are arranged at the two ends of the upper cover and the lower cover. The sealing performance of the whole explosion-proof box is improved.
Furthermore, a metal hoop used for locking the cable is arranged in the lower cover. Can be fixed cable joint in the lower cover, improved the convenience of installation.
Further, the magnetic attraction layer adopts a magnetic powder and silica gel mixing layer. After the upper cover and the lower cover are attracted and spliced, the tightness of the spliced part reaches the standard of preventing moisture from entering.
Contrast prior art, the utility model discloses beneficial effect lies in: the utility model provides an explosion-proof box of cable joint has adopted the mounting means of magnetism concatenation, simple to operate. Be equipped with temperature sensor and humidity transducer in, can real-time detection cable joint's humiture state to send the remote monitoring end through wireless network, can pass through the early warning measure in advance before the occurence of failure, the very first time reports electric power maintainer and overhauls the position, provides safety guarantee and quality guarantee for electric power staff's work. In addition, a fire retardant storage tank is arranged in the upper cover, and the automatic control of fire retardant release is realized through the control unit. In the use, when cable joint explodes or the temperature is too high, can release the fire retardant automatically, can carry out fire-retardant the very first time, have outstanding fire prevention and fire extinguishing effect.
Therefore, compared with the prior art, the utility model has the substantive characteristics and the progress, and the beneficial effects of the implementation are also obvious.
