Description
(1) technical field
The utility model relates to a kind of magnet.Be the Overpressure resistant attracted-iron that can under the abyssal environment condition, use specifically.
(2) background technology
Underwater robot or other underwater hiding-machine need carry out regularly, fix a point to lay and grasp in the deep ocean work process some ferromagnetic material.Realize some ferromagnetic material is carried out regularly, fixes a point to lay and grasp, just need by means of inhaling iron.
Traditional electromagnet contains an electromagnet ontology.This electromagnet ontology is cylindric, is processed with annular chamber in it, is wound with the electromagnetic excitation coil in the annular chamber, and the oral area of annular chamber is welded with annular cover plate.Owing in the annular chamber of this electromagnet the electromagnetic excitation coil is only arranged, in addition be exactly gas, under normal circumstances, the inside and outside pressure of its annular chamber equates.But when using at thousands of meters deep-sea, this ambient pressure can make the annular chamber distortion of electromagnetism body even damage as ambient pressure.
And permanent magnet can use under the abyssal environment condition.But it can only be used to grasp the ferromagnetic material in the deep-sea, can't realize the release to the electromagnetism material that has grasped, more can not be implemented in the extracting and the release that under the abyssal environment ferromagnetic material there are control.
Therefore, above-mentioned electromagnet and permanent magnet can only use on land, can't use under the abyssal environment condition, and range of application is not wide.
(3) summary of the invention
The purpose of this utility model is to provide a kind of Overpressure resistant attracted-iron.This suction iron can not only use on land, can also use the range of application broad under the abyssal environment condition.
Above-mentioned purpose of the present utility model is realized by following technical scheme:
Overpressure resistant attracted-iron of the present utility model comprises electromagnet ontology, and annular chamber is arranged in the electromagnet ontology, and the oral area of annular chamber is opened on the lower surface of electromagnet ontology, and the electromagnetic excitation coil is arranged in it.Be characterized in that the electromagnet ontology upper end for blind end, is processed with through hole in the corresponding position of blind end end and annular chamber one side, this through hole is connected with annular chamber, is useful on the watertight cable connector that links to each other with power source in it.Be filled with withstand voltage silica gel in the electromagnetic excitation coil clearance in the annular chamber.The annular chamber oral area has sealing ring, is slip between the interior lateral wall of the inside and outside circle of sealing ring and annular chamber, the sealing shape cooperates.The annular chamber oral area is useful on the spacing back-up ring that blocks sealing ring.Exhaust outlet is arranged at the top of electromagnet ontology, and vent valve is arranged in the exhaust outlet.
Adopt such scheme, have the following advantages:
Owing to be filled with withstand voltage silica gel in the electromagnetic excitation coil clearance in its annular chamber of Overpressure resistant attracted-iron of the present utility model.The annular chamber oral area has sealing ring, is slip between the interior lateral wall of the inside and outside circle of sealing ring and annular chamber, the sealing shape cooperates.The annular chamber oral area is useful on the spacing back-up ring that blocks sealing ring.When it has ambient pressure (such as the dark deep-seas of thousands of rice) when environment uses down, promptly be filled in the pressure of the withstand voltage silica gel in the electromagnetic excitation coil clearance in its annular chamber, understanding increase along with the increase of ambient pressure.Although the modulus of elasticity in comperssion of withstand voltage silica gel is bigger, along with the continuous increase of pressure, its volume still can dwindle gradually.Because exhaust outlet is arranged at the top of electromagnet ontology, vent valve is arranged in the exhaust outlet again, the air in the annular chamber is extracted out in process of production, make annular chamber interior all substantial except that solenoid by withstand voltage silica gel.When the withstand voltage silica gel volume in the annular chamber during with change in pressure, the sealing ring of its oral area also can slide up and down along with the variation of this pressure, to transmit the pressure inside and outside the annular chamber, makes the inside and outside pressure of annular chamber equate all the time.So, even have under the extremely high pressure situation in the external world, electromagnet ontology does not bear external pressure except that bearing the three-dimensional static pressure, thereby makes system can adopt non-withstand voltage design.Therefore, Overpressure resistant attracted-iron of the present utility model not only can use on land, can also use the range of application broad under the high hydraulic pressure environmental condition in deep-sea of any degree of depth.
(4) description of drawings
Accompanying drawing is an Overpressure resistant attracted-iron structural representation of the present utility model.
(5) embodiment
As shown in drawings, Overpressure resistant attracted-iron of the present utility model contains electromagnet ontology 2, this electromagnet ontology is cylindrical, its upper end is a blind end, corresponding position in blind end end and annular chamber one side is processed with through hole, this through hole is connected with annular chamber, is useful on the watertight cable connector 1 that links to each other with power source in it.In the electromagnet ontology 2 annular chamber is arranged.Said annular chamber is along the longitudinal direction processing of electromagnet ontology 2, and its oral area is opened on the lower surface of electromagnet ontology 2, and electromagnetic excitation coil 4 is installed in it.Except that electromagnetic excitation coil 4, also be filled with withstand voltage silica gel 3 in the annular chamber, make in the gap of electromagnetic excitation coil 4 and enrich with withstand voltage silica gel 3.Electromagnet ontology 2 upper ends are blind end, are processed with through hole in the corresponding position of blind end end and annular chamber one side, and this through hole is connected with annular chamber, is useful on the watertight cable connector 1 that links to each other with power source in it.In the lower end of annular chamber is one section of oral area, sealing ring 5 is installed, the width of sealing ring and the width of annular chamber adapt, and sealing ring 5 can be slided up and down in annular chamber.Said sealing ring 5 should have certain thickness, so that process circumferential recess on its cylindrical.Said circumferential recess is embedded with rubber seal 6, has both realized between sealing ring 5 and annular chamber being slidingly matched thereby make, and has realized sealing again.
On the annular chamber oral area madial wall in sealing ring 5 outsides, be processed with circumferential recess, spacing back-up ring 7 is installed in the circumferential recess, skid off annular chamber to prevent sealing ring 5.
Top at electromagnet ontology 2 is processed with steam vent, and this steam vent is anti-" 7 " font, and its inner is connected with the annular chamber upper end, and its outer end is equipped with vent valve 8.Said vent valve is cock.
