Description

Technical Field

[0001] This invention relates to the field of geophysical exploration technology, specifically to a stratigraphic lithology detection device for geophysical exploration. Background Technology

[0002] Geophysical exploration is one of the commonly used methods in hydrogeological surveys. Its principle is to observe the distribution and changes of various physical fields on Earth using the principles and methods of physics. Geophysical exploration methods mainly include gravity exploration, magnetic exploration, electrical exploration, and seismic exploration.

[0003] Seismic exploration is one of the fastest-developing geophysical methods in modern times. Its principle is to explore underground geological conditions by utilizing the propagation patterns of artificially generated seismic waves within strata with varying elasticity.

[0004] When conducting detection using artificially generated seismic sources, adhering to the principle of minimizing pollution, the method typically involves lifting and releasing a weighted block, which then impacts the ground under gravity to generate vibrations. Generally, a rope is used to lift the weighted block to a certain height to ensure sufficient kinetic energy. However, when releasing the block via rope, the descending weight pulls on the rope, potentially causing overall structural instability and hindering repeated testing. Therefore, this paper proposes an improved stratigraphic lithology detection device for geophysical exploration. Summary of the Invention

A power storage mechanism for storing force on the counterweight column is provided on the lower surface of the mounting block.

[0008] Preferably, the energy storage mechanism includes two symmetrically arranged connecting rods that penetrate the lower surface of the mounting block. A baffle is fixedly connected to the bottom end of each connecting rod. A spring is sleeved on the outer contour of the connecting rod between the mounting block and the baffle. A toothed plate is fixedly connected to the side of the mounting block. A rotating shaft is rotatably connected to the side of the mounting frame near the toothed plate. A missing gear that intermittently meshes with the toothed plate is coaxially fixedly connected to the rotating shaft. A driven gear is coaxially fixedly connected to the outer contour of the rotating shaft near the missing gear. A driving gear that meshes with the driven gear is coaxially fixedly connected to the connecting shaft. The connecting rod abuts against the upper surface of the connecting strip.

[0009] Preferably, the mounting block is provided with a second power storage mechanism, which includes a sliding block that is slidably connected to the surface of the mounting block to store power for the counterweight column. A stop block is fixedly connected to the side of the mounting block near the upper surface. A connecting rod 2 that passes through the stop block and is slidably connected to the top of the sliding block is fixedly connected to the top of the sliding block. A spring 1 is sleeved on the outer contour of the connecting rod 2 between the sliding block and the stop block. The sliding block abuts against the upper surface of the connecting rod.

[0010] Preferably, a mounting plate is fixedly connected to the side of the mounting bracket near the mounting block. A movable rod is fixedly connected to the mounting plate, and a rotating rod is rotatably connected to the movable rod. A torsion spring is sleeved on the outer contour of the movable rod.

A locking block is fixedly connected to the side of the rotating rod near the sliding block, and a locking block is fixedly connected to the surface of the sliding block to cooperate with the locking block and store force.

[0011] Preferably, the side of the stop block near the rotating rod is set with an inclined surface, and the end of the rotating rod near the inclined surface of the stop block is provided with an inclined surface two that cooperates with the stop block. The side of the mounting block near the stop block is fixedly connected with a mounting piece two that limits the rotation angle of the rotating rod.

[0012] Preferably, a connecting plate is fixedly connected to one side of each of the two toothed plates, a connecting column is fixedly connected to the surface of the connecting plate, and a connecting column 2 that cooperates with the connecting column 1 for stable lifting is fixedly connected to the surface of the missing gear.

[0017] 2. By setting up energy storage mechanism one and energy storage mechanism two, the counterweight column can be charged, which can enhance the kinetic energy of the counterweight column without having to lift the entire counterweight column to an excessively high height.

[0018] 3. Inject a fixed amount of water into the mounting base to increase the overall weight of the counterweight column. By injecting water into the mounting base, the overall weight of the counterweight column is changed. By increasing the weight, the overall kinetic energy of the counterweight column is increased, which facilitates subsequent multiple tests using the controlled variable method.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Please see Figures 1 to 7 The present invention provides a technical solution: a geological and physical exploration stratigraphic lithology detection device, including a mounting frame 1 and a fixing frame 2 for supporting and fixing the mounting frame 1. A guide block 3 is fixedly connected to one side of the mounting frame 1. A counterweight column 4 is slidably connected to the guide block 3 through a through groove. A mounting base 8 is fixedly connected to the top of the counterweight column 4. A connecting strip 9 is fixedly connected to the top of the mounting base 8. A lifting mechanism for repeatedly lifting the counterweight column 4 is provided on the surface of the mounting frame 1.

[0030] The lifting mechanism includes two toothed plates 7 symmetrically arranged on both sides of the upper surface of the connecting strip 9. The mounting frame 1 is penetrated and rotatably connected to the connecting shaft 5. The outer contours of both ends of the connecting shaft 5 are fixedly connected to the missing gears 6 that mesh with the toothed plates 7. The surface of the mounting frame 1 is slidably connected to the mounting block 14. The lower surface of the mounting block 14 is provided with a power storage mechanism for storing force on the mounting base 8.

[0031] The power mechanism is a drive motor fixed to one side of the mounting frame 1. The output shaft of the drive motor is fixedly connected to the connecting shaft 5. The drive motor drives the connecting shaft 5 to rotate. When the connecting shaft 5 rotates, the missing gear 6, which is coaxially fixedly connected to the outer contour of the connecting shaft 5, rotates. The two toothed plates 7, which are fixedly connected to both sides of the upper surface of the connecting strip 9, mesh with the two missing gears 6 on the connecting shaft 5. This lifts the mounting base 8 and the counterweight column 4, which are fixedly connected to the connecting strip 9, upwards. Through the missing gears 6, when the counterweight column 4 is lifted to its limit position, it can automatically fall and contact the hard ground, thus impacting the ground and generating an artificial seismic wave source. The seismic wave monitoring instrument is set in a suitable position and used in conjunction with other instruments such as the seismic wave monitoring instrument for analysis and use. The collected information is recorded and saved. Compared with the existing method of pulling up and releasing the counterweight with a rope, the counterweight pulls the rope quickly during release, which can easily cause the support frame to become unstable. At the same time, the release method of mechanical clamping requires the counterweight to be re-fixed and clamped, which is inconvenient for repeated experiments.

[0032] Please see Figure 3 , Figure 5 and Figure 7 The power storage mechanism includes two symmetrically arranged connecting rods 19 that penetrate the lower surface of the mounting block 14. A baffle is fixedly connected to the bottom end of the connecting rod 19. A spring 33 is sleeved on the outer contour of the connecting rod 19 between the mounting block 14 and the baffle. A toothed plate 15 is fixedly connected to the side of the mounting block 14. A rotating shaft 10 is rotatably connected to the side of the mounting bracket 1 near the toothed plate 15. A missing gear 16 that intermittently meshes with the toothed plate 15 is coaxially fixedly connected to the rotating shaft 10. A driven gear 18 is coaxially fixedly connected to the outer contour of the rotating shaft 10 near the missing gear 16. A driving gear 17 that meshes with the driven gear 18 is coaxially fixedly connected to the connecting shaft 5. The connecting rod 19 abuts against the upper surface of the connecting strip 9.

[0033] When the counterweight column 4 moves upward and the connecting bar 9 contacts the connecting rod 19, the spring 2 33 on the outer contour of the connecting rod 19 stores energy in the connecting bar 9. When the gear 6 separates from the toothed plate 7, the counterweight column 4 and the mounting base 8 move downward in the vertical direction and, under the action of the energy storage mechanism, enhance the kinetic energy of the counterweight column 4. The counterweight column 4 generates an artificial vibration source by contacting the hard ground. When the connecting shaft 5 rotates, it enables the driving gear 17, which is coaxially fixed to the connecting shaft 5, to rotate and drive the driven gear. Wheel 18 rotates, causing the missing gear 16, which is coaxially fixedly connected to the driven gear 18, to rotate. When the connecting bar 9 contacts the connecting rod 19, the mounting block 14 slides to its highest position on the mounting frame 1. At this time, the missing gear 16 meshes with the toothed plate 15, causing the toothed plate 15 to move downward in the vertical direction. Under the action of the toothed plate 15, the mounting block 14 pushes the spring 33 to be compressed to its limit position. At this time, the missing gear 16 and the toothed plate 7 are in the limit position of disengagement. As the connecting shaft 5 continues to rotate, the counterweight column 4 is quickly released. Energy is stored in the counterweight column 4 by setting the energy storage mechanism.

[0034] Example 2

[0035] Building upon Example 1, the following is a further step:

[0036] Please see Figure 5 , Figure 6 and Figure 7 The mounting block 14 is provided with a second power storage mechanism, which includes a sliding block 20 that is slidably connected to the surface of the mounting block 14 to store power for the counterweight column 4. A stop block 21 is fixedly connected to the side of the mounting block 14 near the upper surface. A connecting rod 22 that passes through the stop block 21 and is slidably connected to the top of the sliding block 20 is fixedly connected to the top of the sliding block 20. A spring 23 is sleeved on the outer contour of the connecting rod 22 between the sliding block 20 and the stop block 21. The sliding block 20 abuts against the upper surface of the connecting strip 9.

[0037] When the connecting bar 9 comes into contact with the lower surface of the sliding block 20, the spring 23 fitted on the outer contour of the connecting rod 22 pushes the sliding block 20 to slide on the mounting block 14 for a limited position, and the sliding block 20 compresses the spring 23 on the connecting rod 22 to further store force.

[0038] Please see Figure 5 , Figure 6 and Figure 7Mounting plate 25 is fixedly connected to the side of mounting bracket 1 near mounting block 14. Movable rod 26 is fixedly connected to mounting plate 25. Rotating rod 27 is rotatably connected to movable rod 26. Torsion spring 32 is sleeved on the outer contour of movable rod 26. One end of torsion spring 32 is fixedly connected to rotating rod 27. The other end of torsion spring 32 is fixedly connected to mounting plate 25. Locking block 29 is fixedly connected to the side of rotating rod 27 near sliding block 20. Locking block 24, which cooperates with locking block 29 to store force, is fixedly connected to the surface of sliding block 20.

[0039] A locking block 24, which cooperates with the locking block 29 to store force, is fixedly connected to the surface of the sliding block 20. When the connecting bar 9 contacts the lower surface of the sliding block 20, the connecting bar 9 pushes the sliding block 20 to move upward in the vertical direction. As the sliding block 20 moves, the locking block 24 on the sliding block 20 and the locking block 29 on the rotating rod 27 engage with each other, thereby locking the force storage process. Through the torsion spring 32 sleeved on the movable rod 26, the rotating rod 27 can always move closer to the sliding block 20. When the locking block 24 passes through the locking block 29, the rotating rod 27 can automatically reset and remain in contact with the sliding block 20.

[0040] Please see Figure 4 and Figure 6 The side of the stop block 21 near the rotating rod 27 is set with an inclined surface. The end of the rotating rod 27 near the inclined surface of the stop block 21 is provided with an inclined surface second that cooperates with the stop block 21. The side of the mounting block 14 near the stop block 21 is fixedly connected with a mounting plate second 28 that limits the rotation angle of the rotating rod 27.

[0041] The inclined surface of the rotating rod 27 near the stop block 21 is provided with an inclined surface two that cooperates with the stop block 21. When the missing tooth on the missing gear 26 meshes with the tooth plate 25, the missing gear 26 pushes the mounting block 14 to move downward. As the mounting block 14 continues to move downward, when the inclined surface at the end of the rotating rod 27 contacts the inclined surface on the stop block 21, the locking block 29 separates from the locking block 1 24. At this time, the lower surface of the sliding block 20 contacts the connecting strip 9 to further store force.

[0042] Please see Figure 1 and Figure 3 One side of each of the two toothed plates 7 is fixedly connected to a connecting plate 11, and a connecting column 12 is fixedly connected to the surface of the connecting plate 11. The surface of the missing gear 6 is fixedly connected to a connecting column 2 13 that cooperates with the connecting column 12 for stable lifting.

[0043] A connecting column 13, which cooperates with the connecting column 12 for stable lifting, is fixedly connected to the surface of the missing gear 6. As the connecting shaft 5 continues to rotate and the missing gear 6 meshes with the toothed plate 7 again, the connecting column 13 contacts the connecting column 12. As the missing gear 6 rotates, it lifts the connecting column 12 and the connecting plate 11 fixedly connected to the connecting column 12, so that the missing gear 6 can mesh completely with the toothed plate 7. This can effectively improve the stability of the toothed plate 7 in pulling the connecting bar 9 and the counterweight column 4 below the connecting bar 9 to lift them. The experiment can continue, and multiple experiments can improve the accuracy of the experiment.

[0044] Example 3

[0045] Building upon Example 2, the following is a further step:

[0046] Please see Figure 6 The mounting block 14 has a storage chamber 1 for storing water, and the mounting base 8 has a storage chamber 2 for adding counterweight. The upper surface of the mounting base 8 has an opening that communicates with the storage chamber 2. The lower surface of the mounting block 14 is fixedly connected to a connecting pipe 34 that is sealed to the opening on the upper surface of the mounting base 8. The connecting pipe 34 is a retractable corrugated pipe.

[0047] The mounting block 14 has a storage chamber for storing water. When the water in the mounting block 14 is injected into the mounting base 8 through the connecting pipe 34, the weight of the counterweight column 4 is changed by injecting water into the mounting base 8. By increasing the weight, the kinetic energy of the counterweight column 4 is increased, which facilitates subsequent multiple tests by controlling the variable method.

[0048] Please see Figure 4 , Figure 5 and Figure 6 A contact head 31 is fixedly connected to the upper surface of the mounting block 14. A fixing block 30 is fixedly installed on the side of the mounting bracket 1 near the contact head 31. A push switch for injecting water into the mounting base 8 by controlling the connecting pipe 34 is fixedly installed on the lower surface of the fixing block 30.

[0049] When the connecting strip 9 contacts the mounting block 14 and moves upward, it contacts the press switch on the lower surface of the fixing block 30 through the contact head 31 on the mounting block 14. The press switch is turned on, and the flow control valve located in the mounting block 14 injects a certain amount of water into the mounting seat 8, increasing the overall weight of the counterweight column 4. The water storage chamber in the mounting block 14 is connected to an external water pump through a hose, and the water source is transported to the storage chamber in the mounting block 14 by the external water pump.

[0050] Working principle: This geological and physical exploration stratigraphic lithology detection device is used by turning on the drive motor fixed to one side of the mounting frame 1. The output shaft of the drive motor is fixedly connected to the connecting shaft 5. The drive motor drives the connecting shaft 5 to rotate. When the connecting shaft 5 rotates, the missing gear 6 fixedly connected to the outer contour of the connecting shaft 5 rotates. The two toothed plates 7 fixedly connected to both sides of the upper surface of the connecting strip 9 mesh with the two missing gears 6 on the connecting shaft 5, which can lift the mounting base 8 and the counterweight column 4 fixedly connected to the connecting strip 9 upward. When the counterweight column 4 is lifted to the limit position, it can automatically fall and make contact with the hard ground.

[0051] By having the counterweight column 4 contact the hard ground, an impact is achieved, generating an artificial seismic wave source. A seismic wave monitoring instrument is placed in a suitable location and used in conjunction with other instruments such as the seismic wave monitoring instrument for analysis and use. The collected information is recorded and stored. Compared with the existing method of pulling up and releasing the counterweight with a rope, there is no need to re-fix and clamp the counterweight, and it is also convenient to conduct multiple experiments.

[0052] When the connecting shaft 5 rotates, it enables the driving gear 17, which is coaxially fixedly connected to the connecting shaft 5, to rotate and drive the driven gear 18 to rotate. It also causes the missing gear 16, which is coaxially fixedly connected to the driven gear 18, to rotate. When the connecting bar 9 contacts the connecting rod 19, the mounting block 14 slides on the mounting frame 1 to its highest position. At this time, the missing gear 16 meshes with the toothed plate 15, causing the toothed plate 15 to move downward in the vertical direction. Under the action of the toothed plate 15, the mounting block 14 moves until the spring 33 is compressed to its limit position. At this time, the missing gear 16 and the toothed plate 7 are in the limit position of disengagement. The counterweight column 4 will only be released when the connecting shaft 5 continues to rotate.

[0053] When the counterweight column 4 moves upward and the connecting bar 9 comes into contact with the connecting rod 19, the spring 2 33 on the outer contour of the connecting rod 19 stores energy for the entire connecting bar 9. When the gear 16 separates from the toothed plate 17, the toothed plate 17 is released, and the counterweight column 4 and the mounting base 8 move downward in the vertical direction. Under the action of the energy storage mechanism 2, the kinetic energy of the counterweight column 4 can be enhanced, without having to lift the counterweight column 4 to an excessively high height.

[0054] A locking block 24, which cooperates with locking block 29 to store force, is fixedly connected to the surface of sliding block 20. When connecting bar 9 contacts the lower surface of sliding block 20, connecting bar 9 pushes sliding block 20 to move upward in the vertical direction. As sliding block 20 moves, locking block 24 on sliding block 20 engages with locking block 29 on rotating rod 27, thereby locking the force storage process. Through the torsion spring 32 sleeved on movable rod 26, rotating rod 27 can always move closer to sliding block 20. When locking block 24 passes through locking block 29, the force storage process is locked. At 9 o'clock, the rotating rod 27 can automatically reset and keep in contact with the sliding block 20. The inclined surface of the rotating rod 27 near the stop block 21 is provided with the second inclined surface that cooperates with the stop block 21. When the missing tooth on the missing gear 26 meshes with the tooth plate 25, the missing gear 26 pushes the mounting block 14 to move downward. As the mounting block 14 continues to move downward, when the inclined surface at the end of the rotating rod 27 contacts the inclined surface on the stop block 21, the second locking block 29 separates from the first locking block 24. At this time, the lower surface of the sliding block 20 contacts the connecting strip 9 to further store force.

[0055] As mentioned above, when the mounting block 14 moves to its limit position in the vertical direction, it contacts the press switch on the lower surface of the fixed block 30 through the contact head 31 on the mounting block 14, opening the press switch and causing the flow control valve located inside the mounting block 14 to open, injecting a certain amount of water into the mounting base 8, increasing the overall weight of the counterweight column 4. The water storage chamber in the mounting block 14 is connected to an external water pump through a hose, and the external water pump delivers water to the storage chamber in the mounting block 14. When the water in the mounting block 14 is injected into the mounting base 8 through the connecting pipe 34, the weight of the counterweight column 4 is changed by injecting water into the mounting base 8. By increasing the weight, the kinetic energy of the counterweight column 4 is increased, which facilitates subsequent multiple tests by controlling the variable method.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
