The inner portion of the electromagnet body is provided with a ring cavity of which inner portion is positioned with an electromagnet actuating coil. The utility model is characterized in that the upper end of the electromagnet body is a sealing end; the portion on the end portion of the sealing end and corresponding to one side of the ring cavity is processed with a through hole. The through hole is communicated with the ring cavity and the inner portion of the through hole is provided with a watertight cable connector used for connecting with the power source. The above portion of the ring cavity which is the electromagnet body is processed with a through hole communicated with the ring cavity. The outlet of the through hole is provided with a joint of which outer end is equipped with a pressure compensating leather bag. The mouth portion of the ring cavity is positioned on the lower end surface of the electromagnet body. The mouth portion is provided with a ring cover plate and in sealing with the ring cover plate. The inner portion of the ring cavity and the inner portion of a pressure compensating device are filled with overpressure resistant oil. The electromagnet of oil filling type can not only be used on land but also can be used in abyssal environment condition and the application range is wide.
Description
(1) technical field
The utility model relates to a kind of magnet.Be the filling type electromagnet 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 electromagnet ontology 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 filling type to inhale iron.This filling type is inhaled iron, can use on land, can use the range of application broad again at the deep-sea.
Above-mentioned purpose of the present utility model is realized by following technical scheme:
Filling type of the present utility model is inhaled iron, comprises electromagnet ontology, and annular chamber is arranged in the electromagnet ontology, and the electromagnetic excitation coil is arranged in the annular chamber.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 to be processed with the through hole that is communicated with annular chamber on the electromagnet ontology above the annular chamber, the outlet of this through hole has joint, and there is the pressure compensation leather bag outer end of joint.Said annular chamber oral area is opened on the electromagnet ontology lower surface, and this oral area has annular cover plate, and sealing mutually between annular chamber oral area and annular cover plate.Also be filled with withstand voltage oil in the said annular chamber and in the pressure compensator.
Adopt such scheme, have the following advantages:
Because filling type of the present utility model is inhaled iron, is to be processed with the through hole that is communicated with annular chamber on the electromagnet ontology above its annular chamber, there is joint in the exit of this through hole, and there is the pressure compensation leather bag outer end of joint.Also be filled with withstand voltage oil in the annular chamber and in the pressure compensator.Inhale iron when filling type of the present utility model and have when using under the situation of ambient pressure (such as abyssal environment), the pressure of the withstand voltage oil of (promptly being filled in the electromagnetic excitation coil clearance) in its annular chamber can increase simultaneously with the increase of ambient pressure.Although the modulus of elasticity in comperssion of withstand voltage oil is bigger, but along with the continuous increase of pressure, its volume can dwindle gradually, and the pressure compensation leather bag is owing to have enough capacity, can constantly in annular chamber, carry out the oil mass compensation, make the inside and outside pressure of annular chamber equate all the time.Thereby annular chamber distortion, the damage of electromagnet ontology have been avoided.Therefore, filling type of the present utility model is inhaled iron and not only be can be used as the land, can also use the range of application broad under the abyssal environment condition of any degree of depth.
(4) description of drawings
Accompanying drawing is that filling type of the present utility model is inhaled the iron construction schematic diagram.
(5) embodiment
As shown in drawings, filling type of the present utility model is inhaled iron and is contained electromagnet ontology 2, and this electromagnet ontology is cylindrical, is processed with annular chamber in it.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 its upper end is a blind end.Along blind end vertically be processed with through hole, this through hole is connected with the upper end of annular chamber, is equipped with in it to be used for the watertight cable connector 1 that is connected with power source.Be processed with anti-" 7 " font through hole on the electromagnet ontology above the annular chamber 2, the inner end of this through hole is connected with annular chamber, and its outer end is that a joint 8 is installed in its traversing section.Said joint is a tubulose, and its outer end is equipped with pressure compensation leather bag 7.
Be provided with annular cover plate 4 in one section of the annular chamber oral area, be processed with internal and external screw thread respectively on the interior circle of annular cover plate 4 and the madial wall of annular chamber oral area, the two spins together by this internal and external screw thread.
For guaranteeing sealing mutually between annular cover plate 4 and annular chamber oral area, on annular chamber oral area madial wall, be processed with circumferential step, and make annular chamber madial wall diameter under the circumferential step greater than the annular chamber madial wall diameter on the circumferential step.A rubber seal 5 is installed on said circumferential step.Simultaneously, on the cylindrical of annular cover plate 4, be processed with two circumferential recess, all be embedded with rubber seal 5 in this two circumferential recess, and make the degree of depth of the radial thickness of rubber seal 5 greater than circumferential recess.Like this, guaranteed eat dishes without rice or wine the sealing between portion of annular cover plate 4 and annular chamber.
In annular chamber, except that electromagnetic excitation coil 3 is installed, also within it and be filled with withstand voltage oily 6 in the pressure compensation leather bag 7.
