Problems solved by technology

[0005] There are many types of sources in the engineering seismic exploration industry, including explosive sources, vibrator sources, electric spark sources, air gun sources and artificial sources, etc., but all of them have certain disadvantages. Explosive sources have large excitation energy but are not safe, and the use environment is limited; The vibrator works safely but is expensive, and is not suitable for urban areas with dense buildings; the artificial vibrator is convenient to use, but the excitation energy is small, and the energy output is unstable; the electric spark vibrator and the air gun vibrator are not suitable for use in urban areas with dense buildings.

Abstract

The invention discloses a pneumatic impact seismic source. The pneumatic impact seismic source comprises a machine frame, an impact device and a locking device. The pneumatic impact seismic source haslarge excitation energy, is safe and reliable, has simple operation and stable energy output, is not restricted by use environments and applicable to work in urban areas with dense buildings, and islow in cost. The pneumatic impact seismic source can select to perform vertical impact operation or transverse impact operation according to different use environments. During the vertical impact operation, walking wheels on a bottom plate are down to the ground for support; and during the transverse impact operation, walking wheels on lifting plates are down to the ground for support. When the pneumatic impact seismic source performs the transverse impact operation, overall lifting and lowering of the machine frame, the impact device and the locking device can be realized through the liftingand lowering of the lifting device, and the height of an impact rod can be adjusted to adapt to different impact environments.

Description

[0001] Technical field: [0002] The invention relates to a shock source, in particular to a pneumatic shock source. [0003] Background technique: [0004] Seismic wave detection is an exploration method based on the difference in elasticity and density of underground media, by observing and analyzing the amplitude and travel time of artificially excited seismic waves in the formation, and inferring the shape and properties of the underground correspondingly. It has been widely used in energy, minerals, engineering, and geological disasters and the environment and other social fields and has made brilliant achievements. [0005] There are many types of sources in the engineering seismic exploration industry, including explosive sources, vibrator sources, electric spark sources, air gun sources and artificial sources, etc., but all of them have certain disadvantages. Explosive sources have large excitation energy but are not safe, and the use environment is limited; Vibrators ...
