Description

Technical Field

[0001] This utility model belongs to the field of geological exploration equipment technology, and in particular relates to a positioning device for ensuring the consistency of geophones in seismic exploration. Background Technology

[0002] Seismic exploration is the work of investigating and exploring geology through various means and methods. In field seismic exploration operations, it is necessary to ensure that each geophone has a qualified signal triggering capability. Therefore, before the start of seismic exploration, it is usually necessary to test the signal triggering capability of the geophones to ensure that their working condition is stable and qualified, so as to avoid affecting the exploration results.

[0003] Currently, the existing method for detecting detector signal tripping involves inserting the detector onto a designated circular line stretched with nylon thread on a relatively flat surface, and then striking the center of the circle with a sledgehammer or similar excitation device. Ideally, since the detectors are distributed in a ring around the striking point, the spacing should be equal. However, in reality, the spacing between each detector and the striking point often deviates due to factors such as terrain and the irregularity of the nylon thread's circular trajectory, which can affect the detector testing. Therefore, there is an urgent need to overcome and improve the existing methods to provide a positioning device for ensuring detector consistency in seismic exploration. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a well-designed, simple, easy-to-operate, and more accurate positioning device for geophone consistency in seismic exploration, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning device for ensuring detector consistency in seismic exploration includes an outer scale and a rotating connecting assembly. Multiple outer scales are installed at equal angles on the outside of the rotating connecting assembly. A first positioning plate is fixedly provided at the bottom of the end of the outer scale closest to the rotating connecting assembly, and a positioning bolt is threaded onto the outer wall of the end of the outer scale furthest from the rotating connecting assembly. An inner scale is slidably engaged inside the outer scale, and a second positioning plate is fixedly provided at the bottom of the end of the inner scale outside the outer scale. The second positioning plate and the first positioning plate are symmetrically arranged, and a limit component is installed between two adjacent outer scales.

[0007] In a preferred embodiment, the rotary connection assembly includes a central vertical shaft, a limiting disk, and supporting rods. The limiting disks are fixed at both the upper and lower ends of the central vertical shaft. The multiple supporting rods are distributed in a rotating stepped manner around the central vertical shaft, and each of the multiple supporting rods is located between two limiting disks.

[0008] In one preferred embodiment, the plurality of support links correspond one-to-one with the plurality of outer scales, one end of each support link is rotatably connected to the central vertical axis, and the other end of each support link is fixedly connected to the corresponding outer scale.

[0009] In a preferred embodiment, the top outer wall of the inner ruler is engraved with scale lines, and both the first positioning plate and the second positioning plate are inverted right-angled triangular structures.

[0010] In a preferred embodiment, the limiting component includes a first arc-shaped rod, a second arc-shaped rod, a third arc-shaped rod, a first guide groove, and a second guide groove. The second arc-shaped rod and the third arc-shaped rod are sequentially engaged and slidably installed on the inner side of the first arc-shaped rod. The centers of the first arc-shaped rod, the second arc-shaped rod, and the third arc-shaped rod are on the same vertical line as the center of the central vertical axis. The bottom end of the first arc-shaped rod has a first guide groove, and the bottom end of the second arc-shaped rod has a second guide groove.

[0011] In a preferred embodiment, the ends of the first and third arc-shaped rods that are far apart from each other are fixedly connected to two adjacent outer rulers, the bottom of one end of the second arc-shaped rod is provided with a first protrusion, which is engaged and slidably located in the first guide groove, and the bottom of one end of the third arc-shaped rod is provided with a second protrusion, which is engaged and slidably located in the second guide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In the solution of this utility model:

[0014] Multiple sets of limiting components facilitate the control of multiple outer scales to rotate and unfold in a ring around the central vertical axis. Scale markings ensure that the extension length of each inner scale is completely consistent. Tightening the positioning bolts positions the inner scales. Then, the device is inserted into the soil surface via the first and second positioning plates. Multiple geophones are then attached to the ends of the inner scales and installed on the ground, ensuring that the distance between each geophone and the central vertical axis is consistent. During impact testing, this effectively reduces test errors caused by distance and significantly improves the accuracy of geophone test data.

[0015] The first guide groove, the second guide groove, the first protrusion, and the second protrusion facilitate the stable extension and retraction of the limiting component. Moreover, after the work is completed, the device can be rotated and retracted to reduce its size and make it easy to carry. The device is simple to operate and moves quickly to the next excitation point, which is beneficial for use in field seismic exploration. Attached Figure Description

[0025] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0026] like Figure 1-6 As shown, the positioning device for geophone consistency in seismic exploration includes an outer ruler 1 and a rotating connecting assembly 2. Multiple outer rulers 1 are installed at equal angles on the outside of the rotating connecting assembly 2. A first positioning plate 3 is fixedly provided at the bottom of the end of the outer ruler 1 closest to the rotating connecting assembly 2. A positioning bolt 4 is threadedly installed on the outer wall of the end of the outer ruler 1 away from the rotating connecting assembly 2. An inner ruler 5 is slidably engaged inside the outer ruler 1. A second positioning plate 7 is fixedly provided at the bottom of the end of the inner ruler 5 outside the outer ruler 1. The second positioning plate 7 and the first positioning plate 3 are arranged symmetrically. A limit component 8 is installed between two adjacent outer rulers 1.

[0027] Based on the above structure, the rotary connection assembly 2 includes a central vertical shaft 21, a limiting disk 22, and a support link 23. The upper and lower ends of the central vertical shaft 21 are fixed with the limiting disk 22. Multiple support links 23 are distributed in a rotating stepped manner around the central vertical shaft 21, and multiple support links 23 are located between two limiting disks 22.

[0028] Based on the above structure, multiple support rods 23 correspond one-to-one with multiple outer scales 1. One end of the support rod 23 is rotatably connected to the central vertical axis 21, and the other end of the support rod 23 is fixedly connected to the corresponding outer scale 1.

[0029] In this embodiment, the central vertical shaft 21 and multiple supporting rods 23 are used to facilitate the control of multiple outer scales 1 to rotate and adjust around the same center. Furthermore, two limiting discs 22 are used to limit the multiple supporting rods 23 and prevent the central vertical shaft 21 from disengaging from the supporting rods 23.

[0030] Based on the above structure, the top outer wall of the inner ruler 5 is engraved with scale lines 6, and both the first positioning plate 3 and the second positioning plate 7 are inverted right-angled triangular structures.

[0031] In this embodiment, the scale markings 6 facilitate precise control of the extension and retraction length of each inner ruler 5, and the first positioning plate 3 and the second positioning plate 7 facilitate the positioning and placement of the device on the soil surface.

[0032] Based on the above structure, the limiting component 8 includes a first arc-shaped rod 81, a second arc-shaped rod 82, a third arc-shaped rod 83, a first guide groove 84, and a second guide groove 85. The second arc-shaped rod 82 and the third arc-shaped rod 83 are sequentially engaged and slidably installed on the inner side of the first arc-shaped rod 81. The centers of the three arc-shaped rods 81, 82, and 83 are on the same vertical line as the center of the central vertical axis 21. The first guide groove 84 is opened inside the bottom end of the first arc-shaped rod 81, and the second guide groove 85 is opened inside the bottom end of the second arc-shaped rod 82.

[0033] In this embodiment, multiple sets of limiting components 8 are used to facilitate the control of multiple outer scales 1 to rotate and unfold in a ring around the central vertical axis 21. Then, the scale marks 6 are used to control each inner scale 5 to extend by the same length, so as to ensure that the installation distance of each detector from the central vertical axis 21 is consistent. During the tapping test, the test error caused by the distance can be effectively reduced, and the accuracy of the detector test data can be effectively improved.

[0034] Based on the above structure, the ends of the first arc-shaped rod 81 and the third arc-shaped rod 83 that are far apart from each other are fixedly connected to two adjacent outer rulers 1, the bottom of one end of the second arc-shaped rod 82 is provided with a first protrusion 86, the first protrusion 86 is engaged and slidably located in the first guide groove 84, and the bottom of one end of the third arc-shaped rod 83 is provided with a second protrusion 87, the second protrusion 87 is engaged and slidably located in the second guide groove 85.

[0035] In this embodiment, the first guide groove 84, the second guide groove 85, the first protrusion 86 and the second protrusion 87 are used to facilitate the stable extension and retraction of the limiting component 8, and to reduce the size of the device after the work is completed, so as to achieve the purpose of easy portability.

[0036] The working principle of this utility model is as follows:

[0037] In use, firstly, the scale markings 6 engraved on the top outer wall of the inner ruler 5 are used to control each inner ruler 5 to slide out to the specified length. Then, the positioning bolts 4 are tightened to position the inner ruler 5. Subsequently, multiple sets of limiting components 8 and multiple support rods 23 are used to control multiple outer rulers 1 to rotate and unfold around the central vertical axis 21 in a clockwise direction and to form a ring distribution. Figure 1 In the state shown, the device can be stably placed on the soil surface using the first positioning plate 3 and the second positioning plate 7. Then, multiple detectors are attached to the ends of multiple inner rulers 5 and installed on the ground. This ensures that the distance between each detector and the central vertical axis 21 is consistent, which can effectively reduce the test error caused by distance and effectively improve the accuracy of the detector test data.

[0038] During the tapping test, the device is removed. The slots left on the soil surface by the multiple second positioning plates 7 can then form a small ring as a marker, facilitating the operation of a sledgehammer or other excitation equipment to strike the small ring. This allows for the testing of multiple detectors. After the testing is completed, the device can be rotated and retracted using the limiting component 8. Figure 6 As shown, the device has been miniaturized to make it easy to carry. It is simple to operate and can be moved to the next excitation point quickly, making it suitable for use in field seismic exploration and highly practical.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
