Description

Technical Field

[0001] The utility model relates to the technical field of geophysical seismic drop hammer source, in particular to a geophysical seismic drop hammer source. Background Art

[0002] The geophysical seismic drop hammer source is a seismic source device commonly used in seismic exploration and geological surveys. It generates vibration waves by letting the drop hammer fall freely and hit the ground to detect underground structures and stratum characteristics. The working principle of the geophysical seismic drop hammer source is to use the impact force generated by the drop hammer hitting the ground to make the ground vibrate. These vibration waves will propagate through the earth's crust and be reflected, refracted or absorbed by different underground media (such as rocks, soil, groundwater, etc.). By receiving and recording the reflection and propagation information of these vibration waves, the properties and structure of the underground strata can be inferred. For example, application number :202322899572.5 discloses a geophysical seismic drop hammer source, which relates to the technical field of geophysical exploration equipment, and comprises a base, a plurality of round iron pads are placed on the top of the base; a telescopic mechanism is assembled on the top of the base; a vertical plate is assembled on the movable end of the telescopic mechanism, and a test drop hammer mechanism is arranged on the side of the vertical plate; wherein the drop hammer mechanism comprises a support panel fixedly arranged on the side end of the vertical plate, the support panel is provided with two bidirectional threaded rods through a pair of vertical bars, the side ends of the two bidirectional threaded rods are connected by a transmission belt, and the side of the vertical bar is provided with The invention is equipped with a motor for driving a bidirectional threaded rod, and two movable plates are arranged at the middle of the two bidirectional threaded rods at the same time. A through hole for placing a round iron pad is opened at the top center of the support panel, so that the placement of round iron pads of different weight grades can be completed, and the structure is mostly detachable assembly, which is convenient for users to carry it. The device is arranged by placing the round iron pad in the through hole in the support panel and supporting it by two movable plates. When a bidirectional threaded rod is driven to rotate by the motor, the rotation of the bidirectional threaded rod causes the other bidirectional threaded rod to rotate through a transmission belt, so that the two bidirectional threaded rods rotate synchronously, and then the two movable plates on the two bidirectional threaded rods move closer to each other or away from each other, and the two movable plates move away from each other, so that the round iron pad falls freely from the through hole to the ground to generate sufficiently strong artificial seismic waves. If the energy is insufficient or too strong, the weight of the decomposable round iron pad can be arbitrarily increased or decreased. Through the structural design, the placement of round iron pads of different weight grades can be completed. The round iron pad is placed on two movable plates, so that the risk of the round iron pad automatically falling can be avoided, and the structure is mostly detachable assembly, which is convenient for users to carry it;

[0003] The geophysical seismic drop hammer source disclosed in the above patent can support and release the support of the round iron pad by means of two movable plates. When the support is released, the round iron pad falls freely from the through hole to the ground to generate sufficiently strong artificial seismic waves. However, there are still some shortcomings in its use: 1. After the round iron pad falls to the ground, when the drop hammer operation is required again, the round iron pad needs to be picked up manually and put into the round hole for the operation again. This manual picking method requires a large amount of manpower and is more laborious when the round pad hammer is heavy, which cannot meet the use requirements. Based on the above situation, we propose a geophysical seismic drop hammer source. Utility Model Content

[0028] Working principle: When in use, the entire device can be moved by the U-shaped handle and the four walking wheels, and a conventional mobile power supply can be used in conjunction with a plug-in plate to power the first electric slide rail 2, the second electric slide rail 3, the third electric slide rail 10, the electric telescopic rod 11 and the drive motor 16. After moving to the required position, the four T-shaped anchor rods 15 are rotated forward, and the T-shaped anchor rods 15 are moved downward and inserted into the ground while rotating. The four T-shaped anchor rods 15 are used to fix the entire device. By fixing the entire device, the stability during the drop hammer detection process can be improved;

[0029] When performing the drop hammer operation, firstly, the decomposable drop hammer 5 is decomposed according to the detection needs to change its total gravity. When decomposing, the corresponding hammer block 501 can be directly rotated, and the hammer block 501 drives the corresponding threaded block 502 to separate from the hammer block 501. After its total gravity is adjusted, the decomposable drop hammer 5 is placed in the placement box 4 again. At this time, the decomposable drop hammer 5 is located below the middle of the two clamping plates 8. Then, the first electric slide rail 2 is opened in the positive direction, and the sliding end of the first electric slide rail 2 drives the second electric slide rail 3 to move downward, and the sliding end of the second electric slide rail 3 drives the installation box 6 to move downward, and the installation box 6 drives the two clamping plates 8 to move to the decomposable drop hammer through the two screws 7. 5, and then the driving motor 16 is started in the positive direction. The output shaft of the driving motor 16 drives the two screw rods 7 to rotate. Since the threads of the two screw rods 7 are in opposite directions, the two screw rods 7 drive the two clamping plates 8 to move towards each other under the action of the threaded holes on the clamping plates 8. The two clamping plates 8 drive the two anti-skid rubbers 13 to clamp the decomposable drop hammer 5. After clamping, the first electric slide rail 2 is opened in the reverse direction. Similarly, the movement process of the first electric slide rail 2 opening in the positive direction is opposite to that of the first electric slide rail 2, so that the two clamping plates 8 are transformed into moving upward. The two clamping plates 8 drive the decomposable drop hammer 5 to move out of the placement box 4 through the two anti-skid rubbers 13. After moving out, the two clamping plates 8 are synchronously controlled. The switch 12 controls the two electric telescopic rods 11 to open in the forward direction, and the output shaft of the electric telescopic rod 11 drives the support plate 9 to move downward through the corresponding third electric slide rail 10. When the support plate 9 moves downward until its top is flush with the bottom of the decomposable drop hammer 5, the two third electric slide rails 10 can be opened, and the sliding end of the third electric slide rail 10 drives the corresponding support plate 9 to move, and the two support plates 9 move toward each other to support the bottom of the decomposable drop hammer 5. After the support, the first electric slide rail 2 continues to be opened in the reverse direction, so that the decomposable drop hammer 5 continues to move upward. When the decomposable drop hammer 5 moves upward to the required height position, the first electric slide rail can be stopped. 2, then the second electric slide rail 3 is opened in the positive direction, the sliding end of the second electric slide rail 3 drives the installation box 6 to move to the right, the installation box 6 drives the two clamping plates 8 to move to the right through the two screw rods 7, and when the clamping plates 8 drive the decomposable drop hammer 5 to move to the right to the required position, the second electric slide rail 3 can be stopped, and then the driving motor 16 can be started in the reverse direction, so that the two clamping plates 8 are transformed to move away from each other to release the clamping of the decomposable drop hammer 5, and the two third electric slide rails 10 are opened, so that the two support plates 9 are transformed to move away from each other, and the support for the bottom of the decomposable drop hammer 5 is released, so that the decomposable drop hammer 5 falls freely to the ground and generates shock waves;

[0030] When the hammer drop operation is needed again, the first electric slide rail 2 can be started forward again, so that the two clamping plates 8 move downward to the two sides of the decomposable hammer 5 again, and the driving motor 16 can be started forward again, so that the two clamping plates 8 are transformed into moving in the direction of approaching each other again to clamp the decomposable hammer 5. After clamping, the first electric slide rail 2 is started in the reverse direction in the same way as above, so that the decomposable hammer 5 is separated from the ground upward. After separation from the ground, the two electric telescopic rods 11 are started forward again, so that the top of the support plate 9 is flush with the bottom of the decomposable hammer 5. After flushing, the two third electric slide rails 10 are started again, so that the two support plates 9 are moved closer to each other. The bottom support of the decomposable drop hammer 5 is moved in the direction of movement. After the support, the first electric slide rail 2 can be opened again. When the decomposable drop hammer 5 moves upward to the required height, the drive motor 16 and the third electric slide rail 10 can be started in reverse again to release the clamping and support of the decomposable drop hammer 5, and the hammer drop operation can be performed again. When the hammer is dropped again, the decomposable drop hammer 5 is clamped, supported and lifted by electric drive, and there is no need for manual picking operation, which reduces labor intensity. In addition, when the decomposable drop hammer 5 is lifted, the two support plates 9 are used to support it at the bottom, which can effectively reduce the risk of the decomposable drop hammer 5 falling during the lifting process and improve the lifting stability of the decomposable drop hammer 5.
