A waterproof vibrator for deep soil

Abstract

The invention discloses a waterproof vibration exciter for deep soil, comprising a first shell, a second shell, a third shell, an end cover, a miniature high-speed motor, a speed increase mechanism, a vibration generation mechanism, soil anchors, and a speed regulator. One end of the first shell is fixedly connected with one end of the second shell, the other end of the first shell is fixedly connected with the end cover, and the other end of the second shell is fixedly connected with the third shell. The miniature high-speed motor and the speed increase mechanism are fixedly connected into the first shell, the miniature high-speed motor is connected with the speed increase mechanism, and the miniature high-speed motor is in contact with the end cover. The second shell is shaped as a circular truncated cone, and the vibration generation mechanism is arranged in the second shell. The speed increase mechanism is connected with the vibration generation mechanism. The third shell is cone-shaped, and the two soil anchors are symmetrically arranged on the outer wall of the third shell. The miniature high-speed motor is connected with the speed regulator through a waterproof cable. The waterproof vibration exciter for deep soil of the invention has the advantages of simple structure, smooth working, convenient maintenance, continuously adjustable vibration frequency and vibration intensity within a wide amplitude range, and the like.

Description

technical field [0001] The invention belongs to vibration testing equipment, in particular to a waterproof vibration exciter for deep soil. Background technique [0002] In recent years, with the wide application of vibration measurement and vibration test analysis in mechanical engineering and engineering structure departments, vibrator has also been developed rapidly. According to different excitation principles, the current exciters mainly include the following types: the inertial vibrator that uses the eccentric mass to generate the required excitation force, and the alternating current into the moving coil to make the coil operate at a given Electrodynamic exciters and electro-hydraulic exciters that vibrate under the action of electromagnetic excitation force in the magnetic field. [0003] Although these shakers have good applicability in general environments, it is often difficult for these general-purpose shakers to work effectively for vibration test analysis in s...
