Abstract
The invention discloses a kind of auto-power-off devices applied in circuit, including soft iron, semi-ring copper pipe, insulating trip and dilval magnet；The inlet wire of semi-ring copper pipe one end and firewire connects, and the output line of the other end and firewire connects；Semi-ring copper pipe is fixed close to output line one end activity of firewire；Soft iron is set to above semi-ring copper pipe, and dilval magnet is set to below semi-ring copper pipe；Insulating trip is set between dilval magnet and semi-ring copper pipe, the upper and lower surface of the insulating trip is contacted with semi-ring copper pipe, dilval magnet respectively；Dilval magnet outer surface is wound by the end of one or two heat-sensitive line.The configuration of the present invention is simple, install convenient；It could be adapted in the line, use cost is small.When a fire, temperature reaches curie point, and dilval magnet loses magnetism, and due to gravity, dilval magnet falls.Meanwhile semi-ring copper pipe also falls so that semi-ring copper pipe is detached from firewire, is automatically powered off.
Description
Technical field
The present invention relates to a kind of auto-power-off devices applied in circuit.
Background technology
When fire occurs, the first reflection of people is all to go to put out a fire with water.But it is ubiquitous due to present electric wire, in fire
When calamity, people goes fire fighting to there is the security risk being electrically shocked with water.
Invention content
To overcome above-mentioned deficiency, it is an object of the present invention to provide a kind of auto-power-off device applied in circuit, the devices
It is arranged in electric wire, it is ensured that when fire occurs, power off in time.
The solution of the present invention is as follows：A kind of auto-power-off device applied in circuit, which is characterized in that including soft iron,
Semi-ring copper pipe, insulating trip and dilval magnet；
The inlet wire of described semi-ring copper pipe one end and firewire connects, and the output line of the other end and firewire connects；Described half
Ring copper pipe is fixed close to output line one end activity of firewire so that semi-ring copper pipe can surround the end and fall；
The soft iron is set to above semi-ring copper pipe, and the dilval magnet is set to below semi-ring copper pipe, and
There are gaps between soft iron, dilval magnet and semi-ring copper pipe；
Insulating trip is set between the dilval magnet and semi-ring copper pipe, the upper and lower surface of the insulating trip is respectively with half
Ring copper pipe, the contact of dilval magnet；
The dilval magnet outer surface is wound by the end of one or two heat-sensitive line.
Further, protective shell is set outside the soft iron, semi-ring copper pipe, insulating trip and dilval magnet, described is soft
In protective shell, the inlet wire and output line of the firewire pass through protective shell for ferropexy.
Soft iron, semi-ring copper pipe, insulating trip and the dilval magnet of the present invention has been combined into an auto-power-off device, soft
It can be magnetized when iron is close to dilval magnet, by the magnetic attraction of soft iron and dilval magnet, by semi-ring copper pipe, insulation
Piece, dilval magnet are relatively fixed, and dilval magnet is connect with heat-sensitive line.When a fire, the sound end of heat-sensitive line
Temperature is passed into dilval magnet, since dilval can lose magnetism in 103 DEG C of curie point or more, at this moment, ferronickel
Alloy magnet does not have magnetic attraction with soft iron, and due to gravity, dilval is fallen.Meanwhile semi-ring copper pipe is also due to gravity
It acts on one end to fall so that semi-ring copper pipe is detached from firewire, is automatically powered off.
The configuration of the present invention is simple, installation are also very convenient；It could be adapted in the line, use cost is small, effect effect
Fruit is good.
Description of the drawings
Fig. 1 is the structural schematic diagram before present invention power-off.
Fig. 2 is the structural schematic diagram after present invention power-off.
Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings.
A kind of auto-power-off device applied in circuit, including soft iron 1, semi-ring copper pipe 2, insulating trip 3 and dilval
Magnet 4；The inlet wire 5 of 2 one end of semi-ring copper pipe and firewire connects, and the output line 6 of the other end and firewire connects；Semi-ring copper pipe 2 is close
Output line one end activity of firewire is fixed so that semi-ring copper pipe 2 can surround the end and fall；Soft iron 1 is set on semi-ring copper pipe 2
Side, dilval magnet 4 are set to the lower section of semi-ring copper pipe 2, and between soft iron 1, dilval magnet 4 and semi-ring copper pipe 2 there are
Gap；Between dilval magnet 4 and semi-ring copper pipe 2 be arranged insulating trip 3, the upper and lower surface of the insulating trip respectively with semi-ring copper pipe
2, dilval magnet 4 contacts；4 outer surface of dilval magnet is wound by the end of one or two heat-sensitive line.
Protective shell is set outside soft iron, semi-ring copper pipe, insulating trip and the dilval magnet of the present invention, the soft iron is fixed
In protective shell, the inlet wire and output line of the firewire pass through protective shell.
As shown in Figure 1, soft iron, semi-ring copper pipe, insulating trip and the dilval magnet of the present invention have been combined into one automatically
Breaker device can be magnetized when soft iron is close to dilval magnet, will be partly by the magnetic attraction of soft iron and dilval magnet
Ring copper pipe, insulating trip, dilval magnet are relatively fixed, and dilval magnet is connect with heat-sensitive line.
As shown in Fig. 2, when a fire, temperature is passed to dilval magnet by the sound end of heat-sensitive line, due to nickel
Ferroalloy can lose magnetism in 103 DEG C of curie point or more, and at this moment, dilval magnet does not have magnetic attraction with soft iron, due to
Gravity, dilval are fallen.Meanwhile semi-ring copper pipe is also due to gravity one end falls so that semi-ring copper pipe and firewire
It is detached from, plays the role of automatically powering off.
Although the detailed description and description of the specific embodiments of the present invention are given above, it should be noted that
We can carry out various equivalent changes and modification to the above embodiment according to the concept of the present invention, and generated function is made
It, should all be within protection scope of the present invention when with the spirit still covered without departing from specification.
