Beneficial effect of the present invention: the invention discloses a kind of Deap-sea magnetic triggering swith; automatically the disconnection of controlling contact switch by the relative position between contact switch and the magnet is with closed; in the relative motion of magnet or deep-sea switch; rely on the suction of magnet to form switch motion by tongue tube two pole piece adhesives; realize the automation control of deep-sea switch; can be widely used in that the deep-sea is various to be needed in the system that switch motion finishes observing and controlling; deep-sea of the present invention switch is placed directly in the seawater; need not add the pressure resistence cabin body protection; contact switch is arranged in the can of energy bearing certain pressure; can avoid the infiltration and the compacting of seawater, better work to guarantee contact switch.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the structural representation of a kind of Deap-sea magnetic triggering swith of the present invention.
[embodiment]
Be illustrated in figure 1 as the structural representation of a kind of Deap-sea magnetic triggering swith of the present invention.Comprise contact switch 1, shell 2, dielectric 3, closing component 4 and magnet 5, described contact switch 1 is placed on the inside of shell 2, and described magnet 5 is placed on the outside of shell 2, and described dielectric 3 is filled in the shell 2, and closing component 4 is with shell 2 sealings.Described closing component 4 comprises intramedullary expansion nut 41, external compression nut 42 and sealing medium 43, described intramedullary expansion nut 41 is placed on the open interior of shell 2, external compression nut 42 is placed on the opening outside of shell 2, the opening part that intramedullary expansion nut 41 and external compression nut 42 1 work shell 2 compresses, and sealing medium 43 pours in the intramedullary expansion nut 41 and seals.Described contact switch 1 adopts the reed switch contact switch, tongue tube is the simplest passive switch commonly used, it is by Long Circle glass shell, switch contact, form from double-end pin, the glass shell diameter generally has various models at 3-0.5mm, its major parameter is contact capacity and switching speed, can be used as the index that the tongue tube of deep-sea switch mainly considers is the withstand voltage of glass shell, according to voltage-withstand test, the homemade tongue tube of 1mm external diameter can be used on 50MPa, and the homemade tongue tube of 1.5mm can be used on 30MPa.Design from the angle of deep water switch, be sealed in the deformability compression container of filling the dielectric fluid medium, as compressible flexible pipe and sacculus such as rubber, PVC, the device that can use also has transistor switch, Hall switch, reaches all kinds of relays except that tongue tube, but these switches all need to provide power supply, tongue tube need not powered, so as preferred, the present invention adopts passive tongue tube.Shell 2 adopts the PVC flexible pipe, the PVC flexible pipe is not had specific (special) requirements, but must be the matter material of anti-dielectric and seawater corrosion resistance, and its thickness is elected 1-2mm as and got final product.The purpose of filling dielectric 3 is in the switching tube and pipe external pressure Balance Treatment, if there is not filled media in the pipe, even pipe metal sclerine then, if not in the pressure-bearing scope, under high pressure also can produce irreclaimable elastic deformation, thereby damage device in the pipe.According to pressure balance principle, the medium of filling in pipe is generally fluid or semifluid, because their compressed coefficient is little, deformation range under high pressure is little, like this, the PVC flexible pipe has great internal volume deformation range, and pipe inside is the very little liquid of the compressed coefficient, and this switch under high pressure just can not damage.So long as liquid just can satisfy, still, under extra-high voltage, some reed pipe line output seepages even tube wall break theoretically, and nonisulated liquid will make switch conduction, and it is of the present invention preferred therefore adopting dielectric 3 to adopt transformer oil.Intramedullary expansion nut described in the closing component 4 41 adopts the V-type expanding nut, in the V-type expanding nut, be filled with sealing medium 43, the sealing medium 43 of filling can adopt materials such as plastics, epoxy resin, only need play end face seal, do not allow the dielectric oil seepage get final product, fill as the preferred epoxy resin that adopted, if connecting the other end of lead is low-pressure end, the dielectric oil that is in hyperbaric environment can flow to along heart yearn and connect socket, therefore, connecting socket must be the pressure-resistant seal socket.Contact switch 1 is arbitrarily with the relative movement mode of magnet 5, can be that straight line also can be a curve, as long as guaranteeing the tongue tube contact chip just can in the suction scope of the magnetic field of magnet 5, therefore, relevant with magnet 5 suction sizes, but magnet is excessive, and switching speed can be slow, for example straight line moves, magneticaction distance be 20mm, then when magnet just adhesive during near 20mm, and the switch disconnection 40mm that then must relatively move, therefore, when combine and assemble, need select fine strip shape magnet for use, and make magnetic pole strength parallel with switch contact face, reduce spacing as far as possible, improve the sensitivity of switch.For realizing multichannel control, a plurality of dry-reed tube switch can be installed in PVC flexible pipe inside, on the installation site, carry out integrated, on connection mode, carry out the series and parallel combination, when the suction scope is arrived in the magnet relative motion, when both the magnetic line of force passes each switch contact face, switch motion, so just can expand and be multiconductor, multifunction switch.
Embodiment of the present invention is to further specify of the present invention, is not the unique qualification to its structure or material.
