Abstract
The utility model discloses an underwater switch. The solutions are as follows. The switch comprises a sliding switch plate made from ferromagnetic materials and insulating materials; the sliding switch is sealed in the vacuum housing of the switch. The sliding switch plate is further provided with a sliding contact; at the outer part of the vacuum housing is arranged a sliding permanent magnet which is sleeved on the housing and can slide around. On one wall of the vacuum housing is fixedly provided with a fixed contact which is connected with an electric cable. The underwater switch of the utility model is safe for use, convenient for operations and does not get burned or damaged at the contact. The underwater switch is suitable for use on an underwater power supply.
Description
Technical field
The utility model provides the circuit breaker of appliance field, the underwater switch device specifically turn-offing for underwater power source.
Background technology
At present the power supply of submerged cable is controlled on ground conventionally, therefore, in the time of operation under water, cannot turn-off and opening power.
Summary of the invention
Open under water and power cutoff in order to realize, the utility model provides underwater switch device.This derailing switch departs from by permanent magnet driving switch contact or contact contact, realizes the Push And Release of power supply, solves the technical problem of power supply underwater switch.
The scheme that the utility model technical solution problem adopts is:
The slide switch plate that ferromagnetic material and insulating material are made is housed in the vaccum case of sealing, on slide switch plate, there is sliding contact, be set with slip permanent magnet in vaccum case slide outside, on the wall of vaccum case one side, be fixed with fixed contact, fixed contact is connected with cable.
Good effect, the utility model is convenient to underwater switch power supply, therefore, has safety, easy to operate, can not produce the drawback of pitting of contact.The suitable application of the derailing switch as underwater power source switch.
Brief description of the drawings
Fig. 1 is the utility model structure chart
In figure, 1. vaccum case, 2. slip permanent magnet, 3. slide switch plate, 3.1. sliding contact, 4. cable, 4.1. fixed contact.
Embodiment
According to the figure, the slide switch plate 3 that ferromagnetic material and insulating material are made is housed in the vaccum case 1 of sealing, on slide switch plate, there is sliding contact 3.1, be set with slip permanent magnet 2 in vaccum case slide outside, in vaccum case, on the wall of a side, be fixed with fixed contact 4.1, fixed contact is connected with cable 4.
Vaccum case is cylindric or rectangular-shaped.
Slip permanent magnet is Nd-Fe-B permanent magnet or ferrite permanent magnet.
Sliding contact is fixed on the insulated part of slide switch plate.
Slide switch plate is ferrimagnet, as carbon steel or stainless steel.
Cable is single core, two cores or three-core cable, and the end of each core conductor connects a fixed contact.
Work of the present utility model and use procedure:
In the time that needs switch on power, by slip permanent magnet strip, to cable one side, under the adhesive effect of magnetic field of permanent magnet, slide switch plate moves to fixed contact direction, connects cable, and circuit is logical.
In the time of needs power cutoff, by slip permanent magnet strip, to away from cable one side, under the adhesive effect of magnetic field of permanent magnet, slide switch plate moves to departing from fixed contact direction, breaking circuit, and circuit is disconnected.
The utility model uses for the cable switch of boats and ships or Underwater Engineering operation, or application in a humid environment.
