Abstract
The utility model discloses a coil for magnetization and demagnetization of a rare-earth seismic detector. The coil is applied to magnetization and demagnetization of the rare-earth seismic detector of petroleum seismic exploration. Two baffle plates are circular plates, namely the baffle plates are provided with central holes; the two baffle plates are parallel and opposite, metal rods are fixed between the two parallel baffle plates, two ends of the metal rods are fixed on the inner walls of the central holes of the baffle plates respectively, and the metal rods form a cylinder; the distance between the two metal rods is 3 to 10 millimeters; and an enameled copper wire is wound outside the cylinder consisting of the metal rods, the enameled copper wire forms the coil, and insulating glue is filled in the coil. The solidified insulating glue has high strength and is not easily broken. A skeleton consisting of the metal rods is adopted at the heat centralized position of the magnetization coil, and the structure has good heat conducting effect and quick heat dissipation; and the insulating glue with high strength is filled in the coil, so that the coil forms a whole after being completely wound, and the magnetization noise is reduced.
Description
Technical field
The utility model relates to the oil seismic exploration technical field, a kind of charging-erasing magnetic coil that uses in particularly a kind of rare earth geophone manufacture process.
Background technology
Rare-earth permanent magnet has high remanent magnetism and high-coercive force, can optimize the use of wave detector in the application of geophone.But the geophone charging-erasing magnetic of being made by rare-earth permanent magnet is than traditional Al-Ni-Co permanent magnet difficulty, this wave detector magnetize need be very high the magnetic field of magnetizing.
At present, traditional rare earth magnet wave detector coil that magnetizes mainly is made of coil rack and the winding that is wrapped on the skeleton, and coil rack is made by the good insulating material of mechanical strength, and coil windings is formed by the enamelled wire coiling.When in winding by enough big magnetizing during electric current, will in the centre bore of coil, form the high magnetic field of magnetizing, the rare earth wave detector is placed on will finish in this magnetic field of magnetizing and magnetizes.The electric current that magnetizes that magnetic field is required because magnetize is very big, so the coil heating that magnetizes is also very big, and the shortcoming of this traditional structure to be the insulating material skeleton be difficult for heat radiation.The enamelled wire winding mainly is an insulating varnish in traditional coil that magnetizes, and these insulating varnish are very crisp, along with the coil lengthening of service time, will become flexible between the enamelled wire, and noise will increase when magnetizing coil working, forms environmental noise and pollutes.
The utility model content
The purpose of this utility model is: a kind of coil that is used for rare earth geophone charging-erasing magnetic is provided, can realizes rare earth geophone charging-erasing magnetic, and have better heat radiating effect, reduce the coil working noise that magnetizes.
The technical solution adopted in the utility model is: be used for the coil of rare earth geophone charging-erasing magnetic, mainly be made up of baffle plate, Metallic rod and coil, it is characterized in that: two baffle plates are the annular plate, and promptly baffle plate has centre bore; Two baffle plates are parallel relative, two parallel baffle center fixed Metallic rod arranged, and the two ends of Metallic rod are separately fixed on the inwall of baffle plate centre bore, and Metallic rod is formed a cylinder bodily form; Spacing between two Metallic rod is between 3～10 millimeters; The cylinder outer felt of forming in Metallic rod is wound with enamel covered wire, and enamel covered wire is formed coil, is perfused with insulating cement in coil.Require insulating cement to solidify back intensity height, be difficult for broken.
On the wall of every Metallic rod, be coated with the heat conductive silica gel of insulation.
Described baffle plate adopts insulating material to make.
The diameter of Metallic rod is between 0.5～2 millimeter.
The beneficial effects of the utility model: the utility model is used for the coil of rare earth geophone charging-erasing magnetic, the skeleton that adopts Metallic rod to form in the position that the coil heat that magnetizes is concentrated, this structure good heat conduction effect, rapid heat dissipation; Pour into the high insulating cement of intensity in the coil, made coil after coiling is finished, become as a whole, reduced the noise that magnetizes.
