A single rib helical spring leaf

Abstract

The invention discloses a single reinforcement spiral spring piece and particularly relates to the field of geophones. The single reinforcement spiral spring piece is applied to a hanging system of a geophone and characterized by comprising process reinforcement in an Archimedes helix shape and arranged between an inner circular ring and an outer circular ring. The process reinforcement rotates from outside to inside with the rotation angle being 689-738 degrees, and the width of the process reinforcement is decreased from 0.854 mm-0.884 mm to 0.756 mm-0.786 mm from outside to inside. According to the single reinforcement spiral spring piece, the data collecting requirement of high-resolution exploration is met, the natural frequency of the geophone is reduced, seismic exploration deep-layer and low-frequency effective information is effectively picked up, and the fidelity of seismic wave data collecting is improved. By means of the single reinforcement spiral spring piece, the natural frequency of the geophone can reach 1 Hz, and accordingly field usage is more convenient.

Description

technical field [0001] The invention relates to a geophone, specifically designing a single-rib helical spring sheet. Background technique [0002] The spring sheet of the geophone before 2003 was composed of three simple ribs, and the angle between the three ribs was 120 degrees. However, the accuracy of the geophone was not high at that time, and the distortion degree was ≤0.2%, and the false frequency was ≥ 200 is enough. [0003] With the improvement of exploration accuracy, various manufacturers also made different improvements. Later, the spring piece was changed to two process ribs in the inner ring at 180 degrees to each other, and three process ribs in the outer ring at 120 degrees to each other. Improved but insignificant. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method that meets the data acquisition requirements of high-resolution exploration, reduces the natural frequency of the geophone t...
