Embodiment Construction

[0028] Referring to the accompanying drawings, the present invention will be further described in detail with specific embodiments.

[0029] Such as figure 1 As shown, the low-frequency detector includes a housing 1, an upper cover 2, a lower cover 3, an upper coil frame 4, a lower coil frame 5, a magnetic steel 8, an upper yoke 9, and a lower yoke 10. The upper cover 2 is connected to the housing 1, The lower cover 3 is connected with the shell 1, and the shell 1, the upper cover 2 and the lower cover 3 form a shell; the lower yoke 10 is connected with the inner side of the lower cover 3, the magnetic steel 8 is connected with the lower yoke 10, and the upper yoke 9 is connected with the magnetic The steel 8 is connected; the lower end of the upper bobbin 4 and the upper end of the lower bobbin 5 are connected by an adhesive ring to form a bobbin. The counterweight 7 is connected with the coil frame, and the counterweight 7 can be formed by winding enameled wire.

Abstract

The invention relates to a low-frequency detector and aims at solving the technical problems that an existing mechanical vibration-type low-frequency detector is relatively large in size and weight, high in construction cost, inconvenient to construct and transport and very easy to damage. The low-frequency detector comprises a shell, wherein a coil skeleton, an upper yoke and a lower yoke are arranged in the shell; the upper end of the coil skeleton is connected with the upper yoke through at least two upper leaf springs; and the lower end of the coil skeleton is connected with the lower yokethrough at least two lower leaf springs. The low-frequency detector can be applied to the technical field of exploration and engineering vibration measurement.

Description

technical field [0001] The invention relates to a wave detector, in particular to a low-frequency wave detector. Background technique [0002] As we all know, in the field of exploration and engineering vibration measurement, low-frequency geophones are more and more widely used, and there are more and more demands. From the perspective of market demand, everyone hopes that the natural frequency of the geophone should be as low as possible, and the wider the frequency band, the better. it is good. [0003] Referring to the Chinese utility model patent with the authorized announcement number CN204044374U, the natural frequency of the existing geophone based on the principle of mechanical vibration is determined by factors such as the internal elastic element and the quality of the vibrator, so the geophone must be reduced Natural frequency, the usual practice is to reduce the K value (elastic coefficient) of the elastic element, increase the quality of the vibrator and incre...
