Description

Technical Field

[0001] The invention relates to the technical field of engineering blasting, in particular to a source generating device for simulating blasting earthquake surface waves. Background Art

[0002] In the fields of earthquake engineering research, geological exploration and related scientific experiments, the source generator is extremely important for simulating seismic waves. Traditional impact source simulators have been widely used for a long time, but they have many limitations. The seismic waves generated by impact sources have limited energy and a relatively simple waveform, making it difficult to accurately simulate the complex and diverse characteristics of blasting seismic surface waves. This will lead to large data deviations when conducting in-depth studies on the spectrum, amplitude, propagation characteristics, etc. of seismic waves, and cannot meet the needs of high-precision scientific research and engineering analysis. At the same time, with the deepening of research and the expansion of application scenarios, higher requirements are put forward for the energy controllability, waveform diversity and authenticity of simulation effects of the seismic source device. C4 explosives, as an explosive material with excellent performance, have plasticity and can change density through extrusion to enhance the explosive power. If they can be reasonably applied to seismic source devices, they will be able to effectively make up for the shortcomings of traditional impact seismic sources and provide more powerful, more controllable and more realistic seismic source energy for accurate simulation of blasting earthquake surface waves, thereby promoting greater progress and breakthroughs in accuracy and reliability in earthquake-related research and geological exploration technology.

The second connecting circular plate 49 is fixedly connected to the top of the inner wall of the connecting box 48 by a connecting rope 17, and an abutment bar 50 and an electric push rod 6 are fixedly connected to the top of the inner wall of the connecting box 48, and the abutment bar 50 and the electric push rod 6 are located at the left and right ends of the connecting rope 17, and a cutting knife 18 is fixedly connected to the output end of the electric push rod 6, and the cutting knife 18 is adapted to the abutment bar 50.

[0034] The working principle of the present invention is: It is only necessary to place the installation casing 1 at the position where it needs to be installed. At this time, when it is necessary to squeeze the C-4 explosive inside the folding barrel 9, thereby reducing the volume of the folding barrel 9 and increasing the explosive power of the C-4 explosive, it is only necessary to pull the piston 14 upward through the pull handle 10. The abutting disc 15 inside the piston 14 will be closed due to the air pressure, and the abutting discs 15 at the upper and lower ends of the inner wall of the cylinder 11 will open. At this time, air enters the space between the bottom end of the inner wall of the cylinder 11 and the piston 14, and the air between the top end of the inner wall of the cylinder 11 and the piston 14 will enter the folding air sleeve 7. The expansion of the folding air sleeve 7 will drive the abutting air box 8 to squeeze the folding barrel 9. It is worth noting that the installation casing 1 and the multiple groups of connecting rings 23 are folded to the same height. It is assumed that the volume inside the ten groups of connecting rings 23 is equal to half the volume inside the installation casing 1. When the abutting air box 8 drives all the matching tubes 20 to be connected with the corresponding ventilation tubes 24, the gas will push the clamping column 33 to move, and the clamping column 33 drives the moving tube 35 to move. When the moving tube 35 drives the rubber ball 38 to abut against the inside of the limiting ring 25, since the rubber ball 38 is made of rubber material, it can shrink when abutting against the inner wall of the limiting ring 25. When the moving tube 35 moves, it will also drive each group of clamping columns 33 to break away from the abutment with the inner wall of the abutting interface 32. At this time, the gas inside the folding air sleeve 7 will leak out through the ventilation tube 24 and the moving tube 35. When the folding barrel 9 needs to be further squeezed, the folding air sleeve 7 will continue to be inflated. The folding air sleeve 7 drives the matching tube 20 to move through the abutting air box 8. When the gas inside the folding air sleeve 7 becomes weak, the fourth reset spring 31 drives the moving tube 35 to reset. When the moving tube 35 is reset, the rubber ball 38 will be limited by the limiting ring 25 When the second retractable rod 34 is in the position, the rubber ball 38 will pull the second resilient retractable rod 34 through the matching rope 37, and the second resilient retractable rod 34 will become longer. When the outer wall of the second resilient retractable rod 34 abuts against the abutting ball 39, the abutting ball 39 drives the moving frame 41 and the block 29 to move. When the block 29 passes through the first connecting circular plate 27 and the inside of the limiting plate 28, after the moving tube 35 is completely reset at this time, the block 29 will abut against the outer wall of the limiting plate 28, and the moving tube 35 can be limited. Continue to pull the handle 10 again. According to the above working principle, it can be known that the foldable gas sleeve 7 continues to expand. When the foldable gas sleeve 7 continues to expand, at this time, since the moving tube 35 has been limited by the block 29, the foldable gas sleeve 7 can continue to drive the abutting gas box 8 to move downward, and can expand a certain distance each time. The squeezing of explosives will compress the storage space of explosives, thereby increasing the density of explosives and increasing the power when detonated. When it is necessary to detonate the C-4 explosive inside the folding barrel 9, it is only necessary to start the electric push rod 6 through the detonator 5 and the wire 4. The electric push rod 6 drives the cutting knife 18 and the abutment strip 50 to close, and the cutting knife 18 cuts the connecting rope 17. The sixth reset spring 42 drives the second connecting circular plate 49 and the connecting box 48 to move downward rapidly, and the abutment block 47 abuts against the rotating arm 45. The rotating arm 45 will knock the detonator 43 through the knocking ball 44. When the detonator 43 is broken, the C-4 explosive inside the folding barrel 9 is detonated to complete the simulation of the earthquake.
