Specific embodiment
The utility model will be further described below with reference to the accompanying drawings, but is not subject in any way to the utility model
Limitation is transformed or replaced based on any made by the utility model introduction, belongs to the protection scope of the utility model.
A kind of trolley multiple spot power supply safety stop valve as shown in Fig. 1, including automatic cut-off mechanism, using insulation make
At mounting base 1 and protection cap 2, mounting base 1 one end setting input wire casing 3, the other end setting output wire casing 4, cut automatically
Breaking mechanism is set in mounting base 1, and protection cap 2 removably covers in mounting base 1, it is characterised in that: the mounting base 1
Middle part is provided with automatic cut-off mechanism with suitable cutting groove 5, is arranged in the either end of cutting groove 5 to battery plate 6, is connected to battery plate 6
Input wire casing 3 is connect, in the other end setting cutting valve block 7 of the cutting groove 5 opposite with battery plate 6 is given, cutting valve block 7 connects output line
Slot 4, the automatic cut-off mechanism are set in cutting groove 5, and are controlled and touched the dynamic cooperation of formula to battery plate 6 and cutting valve block 7；Its
In, the automatic cut-off mechanism includes magnetic control conducting wire 8, resistor 9, magnetic conductance seat 10, electromagnetic coil 11, switches magnetic patch 12, described
Magnetic conductance seat 10 is set in cutting groove 5, and in the external axial setting electromagnetic coil 11 of magnetic conductance seat 10, the electromagnetic coil 11 passes through
Magnetic control conducting wire 8 connects resistor 9, and the corresponding magnetic conductance seat 10 of the switching magnetic patch 12 is set on cutting valve block 7, makes to switch magnetic patch 12
With the dynamic cooperation of magnetic conductance seat 10.
The magnetic conductance seat 10 is in "U" shaped structure setting, is provided on two columns of magnetic conductance seat 10 interconnected
Electromagnetic coil 11.
The magnetic conductance seat 10 is made of permeability magnetic material.
The cutting valve block 7 is arranged to "~" shape structure.
The switching magnetic patch 12 is permanent magnet.
The resistor 9 is by the connection of magnetic control conducting wire 8 input wire casing 3 or gives battery plate 6.
The cutting valve block 7 is made of the elastic material with conducting function.
The inlet portion of the input wire casing 3, output wire casing 4 is respectively arranged with insulated enclosure circle.
Utility model works principle and the course of work: the input line of one end access mounting base 1 of power input line 13
Fixed in slot 3, the other end connects master control valve, and master control valve supply 13 electric current of power input line is defeated, in 1 other end of mounting base
Export fixed access power supply output line 14 in wire casing 4；Master control valve is closed to after the power supply of power input line 13, is in power input
13 one end magnetic control conducting wire 8 of line is transferred to electric current the resistor 9 being attached thereto, and resistor 9 is conveyed to after being adjusted to be connected therewith
The electromagnetic coil 11 connect, the energization of electromagnetic coil 11 make magnetic conductance seat 10 generate magnetism, and according to the principle of homopolar-repulsion, magnetic conductance seat 10 is produced
Magnetisation is identical as the magnetism on switching magnetic patch 12, generates repulsion therebetween, switching magnetic patch 12 is pushed away to opposite direction, thus handle
Switching magnetic patch 12 shifts cutting valve block 7 at battery plate 6, making to cut off the contact of valve block 7 to battery plate 6 onto, forms closure, gives battery plate at this time
6 transmission electric currents give cutting valve block 7, cut off valve block 7 by the way that electric current is then transferred to power supply output line 14.
When master control valve stop supply 13 input current of power input line or the magnitude of current it is smaller, cause electric current can not be from electricity
When resistance device 9 passes through, the electromagnetic coil 11 connecting with resistor 9 must not be electric, and magnetic conductance seat 10 is nonmagnetic, and switches magnetic patch 12 using certainly
The magnetic absorption of body makes to cut off valve block 7 and gives the disconnection of battery plate 6 to magnetic conductance seat 10, no longer powers to cutting valve block 7 to battery plate 6；It gives
Battery plate 6 just can not by cutting valve block 7 to power supply output line 14 power, realize master control valve stop power supply when, circuit no longer to
Upstream device power supply solves the problems, such as that cutting is not thorough caused livewire work.
