Description

Регулировка собственной частоты известных электродинамических сейсмоприемников обычно осуществл етс  путем установки пружин, обладающих необходимой упругостью. Эта операци   вл етс  весьма трудоемкой и требует почти полной разборки и сборки сейсмоприемника. Дл  упрощени  регулировки собственной частоты подвижной системы электродинамического сейсмоприемника предлагаетс , согласно изобретению , на его корпусе и подвижной системе укрепл ть два обращенных друг к другу разноименными полюсами посто нных магнита с зазором , величина которого может регулироватьс .The adjustment of the natural frequency of known electrodynamic seismic receivers is usually carried out by installing springs with the necessary elasticity. This operation is very time consuming and requires almost complete disassembly and assembly of the geophone. In order to simplify the adjustment of the natural frequency of the moving system of an electrodynamic geophone, it is proposed, according to the invention, to fasten two opposite poles of permanent magnet with a gap, the magnitude of which can be adjusted, on its case and the moving system.

На чертеже изображена схема описываемого сейсмоприемника.The drawing shows a diagram of the described seismic receiver.

К корпусу и подвижной системе сейсмоприемника укрепл ютс  два посто нных магнита 1 w 2, обращенных друг к другу разноименными полюсами. Между магнитами устанавливаетс  зазор 3. Благодар  силе прит жени  между магнитами создаетс  нат жение пружины, несущей инертную масс}, и тем самым в систему вводитс  дополнительна  упругость. Дополнительную упругость можно регулировать путем увеличени  или уменьшени  зазоров между магнитами, и тем самым измен ть степень нат жени  пружины сейсмоприемника, а следовательно, и: его собственную частоту.Two permanent magnets 1 w 2, facing each other with opposite poles, are fixed to the body and the moving system of the seismic receiver. A gap 3 is established between the magnets. Due to the force of the attraction between the magnets, a tension is created that carries the inertial mass}, and thus additional elasticity is introduced into the system. The additional elasticity can be adjusted by increasing or decreasing the gaps between the magnets, and thereby changing the tension of the seismic receiver spring, and, consequently, its own frequency.

Предмет изобретени Subject invention

Электродинамический сейсмоприемник, отличающийс  тем, что дл  регулировки его собственной частоты на корпусе и подвижной системе сейсмоприемника укреплены два обращенных друг к другу раз-ноименными полюсами посто нных магнита, зазор между полюсами которых регулируетс .Electrodynamic seismic receiver, characterized in that in order to adjust its own frequency on the case and the moving system of the seismic receiver, there are two opposite poles of permanent magnet facing each other, the gap between the poles of which is adjustable.
