Abstract
The utility model relates to a switch, in particular to a water sensitive switch for starting a search and rescue system, and discloses a switch for automatically starting a starting search and rescue signal sending device in the case of water entrance. The switch comprises a cuboid switch box and a conductive pin. One end of the conductive pin passes through the switch box and is fixedly connected with the switch box. The other end of the conductive pin is exposed out of the switch box. The position inside the top surface of the switch box relative to the conductive pin is fixedly connected with a spring. The other end of the spring is connected with a movable electroconductive plate. The movable electroconductive plate is hung in the air above the conductive pin. A water swelling layer is filled between the top surface of the switch box and the movable electroconductive plate. The top surface of the switch box is provided with at least one hole. A water swelling waterproof layer is sprayed on the outer surface of the conductive pin which is exposed out of the switch box. The switch for automatically starting the starting search and rescue signal sending device in the case of water entrance has high sensitivity and a simple structure, can be rapidly and automatically started after falling into water and cannot influence the subsequent operation of the search and rescue system.
Description
Technical field
The utility model relates to a kind of switch, relates in particular to a kind of water-sensitive switch that is used to start search and rescue system.
Background technology
When at sea taking place to fall into water accident, can search the wounded and missing crew in the shortest time is to reduce causality loss, saves the inevitable requirement of persons falling in water.Therefore, require personnel, promptly need to start fast search and rescue system, send distress signal in case fall into water.But when accident is fallen into water in general generation, persons falling in water is generally all very nervous, probably can not quick, smooth manually opened search and rescue system, thereby, automatically begin search and rescue system and necessitate, highly sensitive water-sensitive switch promptly becomes and starts the necessary of search and rescue system automatically fast.
The general structure more complicated of existing water-sensitive switch, perhaps sensitivity is lower, if immerse in the water, may influence the operation of follow-up search and rescue system.
Summary of the invention
Have the not high or baroque defective of water-sensitive switch sensitivity at prior art, it is a kind of highly sensitive, simple in structure that the utility model provides, and the switch of search and rescue signal dispensing device is opened in the water inlet that can not influence follow-up search and rescue system operation automatically.
For achieving the above object, the utility model adopts following technical scheme:
The switch of search and rescue signal dispensing device is opened in water inlet automatically, comprise the switch enclosure and the conductive base pin that are shaped as cuboid, one end of described conductive base pin passes and is fixed in switch enclosure, and the other end of conductive base pin exposes switch enclosure, the position affixed spring relative in the switch enclosure end face with conductive base pin, the other end of described spring is connected with movable conductive plate, movable conductive plate is suspended on the conductive base pin top, be the imbibition layer of filling between switch enclosure end face and the movable conductive plate, described switch enclosure end face has at least one hole.When not intaking, movable conductive plate does not contact with conductive base pin under the effect of spring, and switch is conducting not, and after the water inlet, imbibition layer volume high power expands, and the elastic force that overcomes spring makes movable conductive plate contact switch conduction with conductive base pin.
As preferably, the outer surface that exposes the conductive base pin of switch enclosure is coated with the water-swellable water blocking layer.
As preferably, the described water-swellable dope layer that blocks water is the third uncommon sour super-strong moisture absorbing layer.In a single day the third uncommon sour super-strong moisture absorbing layer is met water and can be expanded rapidly, and search and rescue system is carried out water-stop, can not have influence on the operation of follow-up search and rescue system.
It is highly sensitive, simple in structure that the switch of search and rescue signal dispensing device is opened in water inlet of the present utility model automatically, can fast automatic startup after falling into water and can not influence the operation of follow-up search and rescue system.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with Fig. 1,2 and embodiment the utility model is described further.
The switch of search and rescue signal dispensing device is opened in water inlet automatically, as Fig. 1, shown in 2, comprise the switch enclosure 1 and the conductive base pin 21 that are shaped as cuboid, 22, described conductive base pin 21, an end of 22 passes and is fixed in switch enclosure 1 and conductive base pin 21,22 the other end exposes switch enclosure 1, on switch enclosure 1 end face with conductive base pin 21,22 relative affixed two springs 31 in position, 32, described spring 31,32 the other end is connected with movable conductive plate 4, described movable conductive plate 4 is rectangles, with switch enclosure 1 end face homalographic and be suspended on conductive base pin 21,22 tops, be the imbibition layer 5 of filling between described switch enclosure 1 end face and the movable conductive plate 4, described switch enclosure 1 end face has a plurality of holes 6.The outer surface that exposes the conductive base pin 21,22 of switch enclosure 1 is coated with water-swellable water blocking layer 7.Described movable conductive plate 4 is the third uncommon sour super-strong moisture absorbing layer for copper coin, described imbibition layer 5 and water-swellable water blocking layer 7.
Not under the state of Luo Shuiing, the conductive base pin 21,22 that the utility model is coated with the third uncommon sour super-strong moisture absorbing layer is inserted in the switch jack of sender unit of search and rescue system, and the switch and the sender unit of the automatic conducting of water inlet all place on the life vest in the maritime search and rescue. Conductive base pin 21,22 be positioned at switch enclosure 1 part since the elastic force effect of spring do not contact with movable conductive plate 4, can conducting, switch is in off state.
In case the man overboard, seawater enters in the switch enclosure 1 by the hole 6 on switch enclosure 1 end face, and 5 suction of imbibition layer are expanded rapidly, movable conductive plate 4 is ejected with conductive base pin 21,22 contact switch conduction.The third uncommon sour super-strong moisture absorbing layer water-swellable of conductive base pin 21,22 outer sprayings, conductive base pin 21,22 sealings with the switch jack and the switch of the sender unit of search and rescue system, water can not enter in the sender unit of search and rescue system, can not influence the use of sender unit.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model, and all equivalences of doing according to the content of the application's claim change and modify, and all should be technology category of the present utility model.
