Problems solved by technology

[0003] 1) The management of detonators and explosives is very strict, and the seismic team can only use them after the start-up acceptance is completed, which makes the investigation of near-surface structures lag behind and prolongs the construction period
2) There are potential safety hazards and high risks in the storage and transportation of explosives
3) Explosive construction is likely to cause damage to the surrounding surface environment

Embodiment Construction

[0010] A mobile seismic source device according to the present invention includes a car body 1 and a ground anvil 2, the ground anvil 2 is hung on the car body 1, a weight 3 is arranged above the ground anvil 2, and the weight 3 is set by a hydraulic cylinder 5 On the support 4, the support 4 is fixed on the ground cutting board 2, and the hydraulic cylinder 5 is provided with a controller. When working, the controller is turned on to control the weight 3 to impact the ground anvil 2, the ground anvil 2 transmits the vibration signal to the ground, and the seismometer collects the vibration signal reflected from the ground to complete the acquisition and analysis of seismic waves.

Description

technical field [0001] The invention relates to a seismic source device for simulating seismic waves. Background technique [0002] At present, in domestic survey and construction of near-surface structures in oil exploration, seismic wave signals are excited by using explosive sources, which have the advantages of wide signal frequency range and strong energy. However, since the detonators and explosives involved are dangerous goods, there are many problems in management, storage, transportation and construction: [0003] 1) The management of detonators and explosives is very strict, and the seismic team can only use them after the start-up inspection is completed, which makes the investigation of near-surface structures lag behind and prolongs the construction period. 2) There are potential safety hazards and high risks in the storage and transportation of explosives. 3) Explosive construction is likely to cause damage to the surrounding surface environment. 4) The cons...
