Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is further embodiment of this invention structural schematic diagram.
Description of symbols: insulation crust 1, water seepage hole 11, upper magnet 2, lower magnet 3, floating body 4, supporter 41, sliding
Column 5, resistance 6, lower binding post 7, upper binding post 8.
Specific embodiment
Technical solution of the present invention is described further below in conjunction with attached drawing.
As shown in Figure 1, the protective device of the anti-electric leakage of paddling of low pressure of the invention includes insulation crust 1, upper magnet 2, lower magnetic
Iron 3, floating body 4, slide post 5, resistance 6, lower binding post 7, upper binding post 8, wherein 1 bottom of insulation crust or surrounding setting are multiple
Water seepage hole 11, for external water to be flowed into insulation crust 1 after external ponding, two slide posts 5 of setting inside insulation crust 1,
Lower magnet 3, floating body 4 is arranged in the insulation crust 1 of 5 lower section of slide post, and lower magnet 3 is arranged above floating body 4, lower 3 He of magnet
Upper magnet 2 is alnico magnets, and the magnetism of 3 top of lower magnet is opposite with the magnetism of upper 2 lower section of magnet.Upper magnet of the invention
2 are arranged above insulation crust 1.The component that lower magnet 3, floating body 4 form can be moved up and down along slide post 5, such as be filled in inside
When entering water, the buoyancy of floating body 4 drives lower magnet 3 to move up.
As shown in Figure 1, being provided with lower binding post 7 under the present invention on magnet 3, binding post is provided with above insulation crust 1
After 8, upper binding post 8 is electrically connected by conducting wire with exchanging, and the component of lower magnet 3, floating body 4 composition moves up, upper binding post 8 with
Lower binding post 7 just contacts.
As shown in Figure 1, present invention available wire between two lower binding posts 7 connects a resistance 6, the resistance of resistance 6
Value can ensure that circuit trips, and such as in alternating current 220V, breaker is 10A tripping, then resistance 6 can choose 0 to 20 ohm
Value, may insure to trip in this way, but preferably 10 to 20 ohm of resistance 6, in this way can be to avoid the generation of circuit spark phenomenon.
As shown in Fig. 2, resistance 6 of the invention also can be set on upper binding post 8.
As shown in Figure 1 and Figure 2,4 lower part of floating body of the invention is preferably provided supporter 41, and supporter 41 and floating body 4 can
Such to be advantageous in that be wholely set, the device of the invention, which may need the several years just after placing, can work once, if by this
A floating body 4 is placed on insulation crust 1, and floating body 4 may be pasted together with insulation crust 1, and after paddling, it cannot float
It is floating, cause the present invention can not work normally.Supporter 41 can be with the contact of less floating body 4 and insulation crust 1, it is ensured that puts the more
Year the device of the invention remains to work normally.
The course of work of the invention is: being possible to be flooded place not, in the place of outside need alternating current, simultaneously will
In upper 8 parallel connection of binding post of two of the present apparatus, and the present apparatus is placed below the side for needing protective device.When equipment is by water
When flooding, floating body 4 pushes lower magnet 3 and lower binding post 7 to move up, when upper magnet 2, lower magnet 3 are closer to, due to polarity
On the contrary, its mutual attraction contacts lower binding post 7, upper binding post 8 reliably, cause current overload, make it is external after
Electric appliance tripping, and then ensure that route powers off, and due to being flooded not, entire route can be in unsafe condition, not to this
When invention device working line repairs, the device of the invention can be always maintained at on-state, it is ensured that the safety of passerby.
