Utility model content
The purpose of this utility model be propose a kind of cause danger in inside situation time, the safe power distribution box of distribution box door can be easy to open.
Safe power distribution box of the present utility model comprises casing and chamber door, and key is that the side sidewall of described casing is provided with mounting cylinder, and described mounting cylinder is towards the one end open of chamber door, and the sidewall of mounting cylinder is provided with fixing hole; Described chamber door is provided with hinge, described hinge is made up of the rotating shaft of rotation support portion, fixed support portion and connection of rotating support portion, fixed support portion, described chamber door is fixedly connected with rotation support portion, described fixed support portion is provided with erection column, described erection column is inserted in mounting cylinder by the openend of mounting cylinder, the position of the corresponding fixing hole of erection column is provided with pin hole, and erection column utilizes through fixing hole and the iron pin be inserted in pin hole is fixedly connected with erection column; The spring of compressive state is folded with between the head of a nail of described pin and the outer wall of mounting cylinder; Described casing is provided with electromagnet at the opposite place of fixing hole, and described electromagnet is connected with a controller, and described controller is connected with Smoke Sensor and/or current sensor.
The operation principle of above-mentioned safe power distribution box is as follows:
Distribution box Power supply normal and there is no overcurrent in distribution box, the situation such as to catch fire time, controller controls electromagnet energising, the magnetic of electromagnet applies suction to iron pin, pin is made to overcome the elastic force of Compress Spring and be stable in pin hole, now erection column cannot be deviate under the effect of pin, thus the rotation support portion of hinge is fixedly connected with wall box, chamber door can only with opening box door lock, rotate the mode of chamber door and open.
When the situation such as occur overcurrent in distribution box, catch fire, controller controls electromagnet power-off, the magnetic of electromagnet disappears, pin is deviate under the elastic force effect of Compress Spring in pin hole, erection column is without the restriction of pin, freely can deviate from mounting cylinder, now chamber door can directly be extracted together with hinge and open, and without using key operated box door lock.
When power-off appears in the power supply in distribution box, electromagnet nature is without magnetic, and now chamber door can directly be extracted together with hinge and open, and without using key operated box door lock.
Specifically, described controller comprises single-chip microcomputer and relay, a control end ground connection of described relay, and another control end is connected with the output pin of corresponding single-chip microcomputer; A lead-out terminal of relay is used for being connected with power supply, and another lead-out terminal is by electromagnet ground connection.Whether single-chip microcomputer by output low level or high level signal, carrys out control relay whether adhesive, thus control the electromagnet that this relay connects and be energized.
Further, described mounting cylinder is provided with anti-delinking part at the side of fixing hole, and described anti-delinking part is made up of one section of closed cell body, and described cell body connects with fixing hole; The head of a nail and the Compress Spring of described pin are all positioned at cell body.When losing magnetism when electromagnet power-off, Compress Spring by pin in pin hole to outer promotion, until the blind end of lug cap and cell body offsets, so just while releasing pin is to the restriction of erection column, pin can be avoided to be bound to other position and to cause new dangerous situation.
Further, for ease of observing the inner case of distribution box, described chamber door has part at least for transparent.
Safe power distribution box of the present utility model by improving hinge, can catch fire in distribution box, the dangerous situation such as overcurrent or power loss time, chamber door can being opened without the need to opening box door lock, improve the time of preciousness for recovering, there is good fail safe.
