Abstract

The invention relates to a light air-pressure type shallow water area earthquake wave full-automatic trigger which comprises a framework and a shocking hammer body (5), wherein the framework is arranged in a ship body (1), the upper end of the framework is connected with a cylinder (12) which is connected with an air source through a pipeline, a lifting hook (10) is connected with a piston rod (11) of the cylinder (12) in a hinged mode, and the shocking hammer body (5) is matched with the lifting hook (10) in a connecting mode. Overturning is produced when the lifting hook (10) contacts with a limiting plate (8), and then the shocking hammer body (5) falls off and is matched with a cushion plate (3) arranged on the bottom of the ship body in a colliding mode, and earthquake waves are produced. According to the light air-pressure type shallow water area earthquake wave full-automatic trigger, the earthquake waves produced are moderate in energy and frequency band, low in noise waves, and adjustable and fixable in the energy and impacting frequency. Meanwhile, the light air-pressure type shallow water area earthquake wave full-automatic trigger is light, portable, convenient to carry due to the fact that total weight of the trigger is less than 60 k, and is suitable for being used in shallow water areas and sites without hoisting devices.

Description

technical field [0001] The invention relates to a seismic wave generating device, in particular to a light air pressure type automatic trigger for shallow water seismic waves. Background technique [0002] Existing seismic wave generating devices mainly contain the following types: spark source, air gun source, seismic gun source, shock source and explosive source. [0003] (1) Spark source [0004] The principle of the spark source is a device that uses the discharge effect of high-voltage electrodes in water to excite earthquakes. Before excitation, the high-voltage rectifier circuit first charges the high-voltage capacitor to tens of kilovolts, and the high-voltage capacitor is connected to a pair of electrodes placed in seawater through a discharge cable and a discharge switch. When excited, the discharge switch is turned on, the electrodes suddenly obtain a high voltage of tens of kilovolts, and a discharge current of hundreds of thousands of amperes is formed in the ...
