The utility model discloses in, fix on the mounting panel through the key equipment with the switch to set up the spring in the bottom of mounting panel, the vibrations that produce when the explosion that significantly reduces through the stiffener that sets up have reduced the probability that explosion-proof shell is by extrusion deformation, and through the stand-by power supply who sets up, guarantee that the switch can normally work a period after external power supply is cut off, provide necessary condition for underground and ground communication.
Description
Technical field
This utility model relates to network switch field, particularly relates to a kind of flame proof network switch.
Background technology
EPA has had practical application on the ground, but at underground coal mine but without application. Coal Mine Safety Supervision Bureau of country proposes in formulation " Coal Mine Safety Monitoring Systems safety condition " seminar recently held about leader and expert, use EPA as the backbone transport network of down-hole, fieldbus as the network connecting the field apparatus such as sensor, it may be that the research emphasis of mine transmission network and constructive direction at no distant date. It is contemplated that, the inevitable choice that EPA also will be following mine broadband communication network construction.
But, existing flame proof switch has only done technological processing for explosion protection feature on the shell of switch, at that time down-hole blast accident time, switch is highly susceptible to strenuous vibration and crimp, cause equipment malfunction and damage, and after blast, if external power source is cut off, switch also cannot be properly functioning, ultimately results in ground and down-hole lost contact and rescue work is difficult to situation about carrying out.
For this, it is proposed that a kind of flame proof network switch solves the problems referred to above.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of flame proof network switch proposed.
To achieve these goals, this utility model adopts the technical scheme that
A kind of flame proof network switch, including flameproof enclosure, described flameproof enclosure is provided with an entrance hole and multiple wire hole, the side inwall of described flameproof enclosure is fixed with multiple spring, described spring is fixed with installing plate away from one end of inwall by lock-screw, being provided with the network switch, AC transformer and apparatus for storing electrical energy on described installing plate, described installing plate is provided with circular hole;Described flameproof enclosure inwall is provided with bracing piece; The outfan of described AC transformer connects the network switch and apparatus for storing electrical energy, the outfan of described apparatus for storing electrical energy also with network exchange mechatronics.
Preferably, the both sides of described flameproof enclosure are provided with louvre, and are provided with Air Filter in louvre.
Preferably, bracing piece adopts the steel of high intensity to make.
Preferably, described apparatus for storing electrical energy is made up of inverter and accumulator.
In this utility model, by by the network switch, the key equipment of the switch such as AC transformer and apparatus for storing electrical energy is fixing on a mounting board, and spring is set in the bottom of installing plate, greatly reduce the vibrations that explosion time produces, by the bracing piece arranged, reduce the probability that explosion-resistant enclosure is deformed, protection key equipment is without damage, and the stand-by power supply by arranging, ensure switch energy normal operation a period of time after external power source is cut-off, the condition of indispensability is provided for down-hole and ground communications, rescue work after occurring for accident brings convenience.
