Description

Technical Field

[0001] The embodiments of the present invention relate to the field of seismic exploration technology, specifically to a seismic detector for three-dimensional seismic exploration. Background Technology

[0002] 3D seismic exploration is a geophysical exploration method that utilizes the reflection and refraction properties of seismic waves as they pass through underground rock layers to detect subsurface geological structures and potential mineral resource distributions. Compared to traditional 2D seismic exploration, 3D seismic exploration provides more accurate spatial images, which is particularly important for the discovery and assessment of oil and gas reservoirs. In the process of 3D seismic exploration, seismic wave data needs to be detected by seismic detectors. Since seismic detectors are mostly used in the field and lack effective protective measures, impurities such as water vapor and dust in the field can easily corrode the seismic detectors, affecting their application performance.

[0003] To address these issues, we propose a seismic detector for three-dimensional seismic exploration. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a seismic detector for three-dimensional seismic exploration, which solves the technical problem that the lack of effective protective measures in the prior art makes the seismic detector easily corroded by impurities such as water vapor and dust in the field, thus affecting the application effect of the seismic detector.

Four clearance slots are opened at the bottom edge of the hollow shaft. The four anti-rotation plates extend through the four anti-rotation plates to the outside of the hollow shaft. A limiting component is assembled at the bottom end of one of the sealing plates to cooperate with the anti-rotation plate to form a normal anti-rotation limiting position for the hollow shaft.

[0008] For example, in a three-dimensional seismic detector for seismic exploration provided in at least one embodiment of the present invention, the limiting component includes: A stabilization frame is fixedly connected to the bottom end of one of the sealing plates.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-10 As shown, it illustrates a seismic detector for three-dimensional seismic exploration in one embodiment of the present invention. In some examples, including: A central cover 1 is provided. A magnet 2 is fixedly connected to the bottom of the central cover 1. A mounting cylinder is sleeved on the top of the magnet 2. A coil 3 is wound around the outside of the mounting cylinder. A spring sheet 4 is provided between the top of the mounting cylinder and the central cover 1. The wire guide shell 5 has a wire guide tube 6 at the middle of both ends of the wire guide shell 5. An extension seat 7 is fixedly connected to the inner wall of one end of the wire guide shell 5. A locking hole 8 is opened at one end of the extension seat 7. Two protective components 9 are respectively assembled at both ends of the cable guide shell 5. The protective components 9 are used to cooperate with the cable guide shell 5 to form a centralized cover 1 for protection. A plug 10 is provided between the bottom ends of the two protective components 9.

[0027] For example, such as Figure 3 As shown, an insulating ring 38 is provided on the inner edge of the central cover 1, and multiple sealing rings 39 are fixedly connected to the outer side of the insulating ring 38.

[0028] More specifically, the material of insulating ring 38 can be: Polytetrafluoroethylene (PTFE): A material resistant to high temperatures and chemical corrosion, possessing excellent insulation and resistance to low-temperature aging. It retains its flexibility and elasticity even at low temperatures. Polyimide: a thermoplastic polymer that is resistant to high temperatures and chemicals, has excellent mechanical properties and insulation characteristics, and can maintain its mechanical strength and elasticity even at low temperatures; For example, such as Figure 5 As shown, both protective components 9 include: The support frame 11 is slidably connected to the bottom end of the cable passage shell 5. A positioning seat 12 is fixedly connected to the top of one end of the support frame 11. A support shaft 13 is rotatably connected to the inner side of the positioning seat 12. A sealing plate 14 for sealing the top of the cable passage shell 5 is fixedly connected to the outer side of the support shaft 13. The protective cover 15 is fixedly connected to the bottom end of the support frame 11, and the central cover 1 is assembled between the two protective covers 15. The bottom end of the protective cover 15 is provided with a mounting groove 16, and the plug 10 is assembled between the two mounting grooves 16. Positioning strip 17 is fixedly connected to the edge of one side of one of the protective covers 15. The end of positioning strip 17 away from the protective cover 15 is fixedly connected to a retaining strip 18. The other protective cover 15 has a quick-installation slot 20 on the side near the retaining strip 18. The end of the quick-installation slot 20 has a quick-installation slot 19, and the retaining strip 18 is engaged with the quick-installation slot 19. The stop assembly 21 is mounted on one end of one of the sealing plates 14 and is used to cooperate with the locking hole 8 to form a normal locking of the sealing plate 14.

[0029] In this embodiment, the protective cover 15 can be made of plastic. Due to the material properties of the protective cover 15, when the clip 18 presses the quick-release slot 20, the protective cover 15 can undergo a certain deformation so that the clip 18 can be inserted into the quick-release slot 19. For example, such as Figure 4 As shown, a guide bar 40 is fixedly connected to the bottom of one end of the wire housing 5, and a guide groove 41 is provided at the end of the support frame 11 near the guide bar 40, and the guide bar 40 is also slidably connected inside the guide groove 41.

[0030] More specifically, through the connection of guide bar 40 and guide groove 41, when the support frame 11 is connected to the cable guide shell 5, firstly, guide bar 40 is aligned with guide groove 41, and protective cover 15 is pushed, so that the support frame 11 is slidably installed at the cable guide shell 5 under the limit of guide bar 40. For example, such as Figure 5 and Figure 7 As shown, one end of another sealing plate 14 is fixedly connected to a linkage rod 43. One of the sealing plates 14 has a linkage hole 44 at the end near the linkage rod 43, and the linkage rod 43 is also inserted into the interior of the linkage hole 44.

[0031] More specifically, through the structural cooperation between the linkage rod 43 and the linkage hole 44, when the two sealing plates 14 approach each other, the linkage rod 43 will be inserted into the linkage hole 44, thereby realizing the linkage between the two sealing plates 14. When either sealing plate 14 is pulled in the future, the two sealing plates 14 can be rotated synchronously. In this embodiment, sealing strips are fixedly connected to the sides of the two sealing plates 14 that are close to each other and the bottom edge of the sealing plate 14. By setting the sealing strips, the gaps between the two sealing plates 14 and between the sealing plate 14 and the wire passage shell 5 can be sealed, preventing moisture and dust from entering the wire passage shell 5 through the gaps.

[0032] For example, such as Figure 5 As shown, multiple retainers 42 are fixedly connected inside the two protective covers 15, and each retainer 42 has an anti-slip pad at one end. More specifically, by setting up the retainer 42, after the central cover 1 is installed, the retainer 42 can be used to provide auxiliary support for the central cover 1, so as to avoid uncontrollable movement after the central cover 1 is installed, and greatly ensure the stability of the application of the central cover 1.

[0033] For example, such as Figure 6 As shown, both the locking strip 18 and the quick-release slot 19 are circular structures, and the diameter of the locking strip 18 is smaller than the width of the quick-release slot 20. More specifically, through the structural characteristics of the retaining strip 18 and the quick-release slot 19, when the retaining strip 18 comes into contact with the quick-release slot 20, the protective cover 15 at the retaining strip 18 is continuously pushed, so that the retaining strip 18 squeezes the quick-release slot 20, causing the quick-release slot 20 to deform, until the retaining strip 18 moves through the quick-release slot 20 into the quick-release slot 19. Since the quick-release slot 20 will lose its compression after the retaining strip 18 moves into the quick-release slot 19, the quick-release slot 20 can then recover through the quick-release slot 20, forming a blockage of the retaining strip 18.

[0034] For example, such as Figure 8 As shown, the stop assembly 21 includes: Hollow shaft 22 is vertically rotatably connected to one end of one of the sealing plates 14. An extension rod 23 is fixedly connected to one side of the bottom of the hollow shaft 22. A locking rod 24 is fixedly connected to one end of the extension rod 23, and the locking rod 24 is engaged with the locking hole 8. Positioning plate 25 is fixedly connected to the middle of hollow shaft 22. A displacement rod 26 is vertically slidably connected to the middle of positioning plate 25. A transmission plate 27 is fixedly connected to the top of displacement rod 26. A helical spring 28 is fixedly connected between the top of positioning plate 25 and transmission plate 27. The guide plate 29 is fixedly connected to the bottom end of the displacement rod 26. Four anti-rotation plates 30 are fixedly connected to the outer side of the guide plate 29. Four clearance slots 31 are opened at the bottom edge of the hollow shaft rod 22. The four anti-rotation plates 30 extend through the four anti-rotation plates 30 to the outside of the hollow shaft rod 22. A limiting component is installed at the bottom of one of the sealing plates 14 to cooperate with the anti-rotation plate 30 to form a normal anti-rotation limit for the hollow shaft 22.

[0035] For example, such as Figure 10 As shown, both the lock hole 8 and the locking rod 24 are arc-shaped structures; More specifically, through the structural characteristics of the locking hole 8 and the locking rod 24, as the locking rod 24 rotates with the hollow shaft 22, the locking rod 24 can be smoothly connected to the locking hole 8 by screwing in, while ensuring the stability of the connection between the locking rod 24 and the locking hole 8.

[0036] In this embodiment, the top of the transmission plate 27 is provided with an internal hexagonal groove. The internal hexagonal groove allows personnel to easily rotate the transmission plate 27 with the help of a hexagonal wrench. Meanwhile, in this embodiment, a sealing gasket is fixedly connected to the edge of the top of the transmission plate 27. By setting the sealing gasket, under normal conditions, the gap between the top of the transmission plate 27 and the hollow shaft 22 will be sealed by the sealing gasket, so as to prevent moisture and dust from entering the wire housing 5 through the connection gap between the transmission plate 27 and the hollow shaft 22. For example, such as Figure 8 As shown, the limiting component includes: The stabilization frame 32 is fixedly connected to the bottom end of one of the sealing plates 14. The bottom end of the stabilization frame 32 is fixedly connected to the stabilization plate 33. The bottom edge of the stabilization plate 33 is provided with four slots 34, and four anti-rotation plates 30 are respectively engaged and connected inside the four slots 34. The top end of the stabilization frame 32 is provided with a limit sliding groove 35. The limiting plate 36 is fixedly connected to the side of the hollow shaft 22 near the limiting groove 35. The bottom end of the limiting plate 36 is fixedly connected to the limiting rod 37, and the limiting rod 37 is also movably connected inside the limiting groove 35.

[0037] In this embodiment, the limiting slide 35 is arc-shaped, and the limiting rod 37 can move within the limiting slide 35 at an angle of 90 degrees. Through the connection between the limiting slide 35 and the limiting rod 37, the rotation angle of the hollow shaft rod 22 does not exceed 90 degrees. When the limiting rod 37 is blocked by the limiting slide 35, the extension rod 23 can be rotated to a designated position to remind the personnel that the locking rod 24 has been connected or disengaged. In this embodiment, the included angle between two adjacent slots 34 is 90 degrees, so that after the hollow shaft 22 rotates, the anti-rotation plate 30 can still correspond to the slot 34, ensuring the connection stability between the anti-rotation plate 30 and the slot 34. Working principle: First, align the guide grooves 41 at the two support frames 11 with the two ends of the guide strip 40 respectively, and place the plug 10 between the two mounting grooves 16. Then, push the protective cover 15 so that the two support frames 11 move closer to each other along the guide strip 40 until the locking strip 18 contacts the quick-connect groove 20. Then, push the two protective covers 15 at the same time to expand the quick-connect groove 20 with the help of the locking strip 18 until the locking strip 18 passes through the quick-connect groove 20 and reaches the inside of the quick-connect groove 19. When the locking strip 18 reaches the quick-connect groove 19, the quick-connect groove 20 loses its compression, and the locking strip 18 can be locked inside the quick-connect groove 19 by the recovery of the quick-connect groove 20. In this way, the two protective covers 15 are assembled and the plug 10 is positioned with the help of the mounting groove 16. The concentrator 1 is installed between two protective covers 15, and the wiring harness of the concentrator 1 is led out through the lead wire tube 6. Then the plug 10 is inserted into the designated detection position. In this embodiment, the magnet 2 has strong magnetism, and the coil 3 is made of copper enameled wire wound on the mounting tube and has two output ends. The spring plate 4 is made of specially made phosphor bronze and has a linear elastic coefficient. It connects the coil 3 and the concentrator 1 together, so that the coil 3 and the concentrator 1 form a relatively moving body. When there is mechanical vibration on the ground, the coil 3 moves relative to the magnet 2 and cuts the magnetic lines of force. According to the principle of electromagnetic induction, an induced electromotive force is generated in the coil 3, and the magnitude of the induced electromotive force is proportional to the relative speed of the coil 3 and the magnet 2. The analog electrical signal output by the coil 3 is consistent with the speed change law of the ground mechanical vibration, thereby realizing three-dimensional seismic exploration. Furthermore, regarding the sealing of the top of the cable pass-through housing 5, before the two protective covers 15 come into contact with each other, the two sealing plates 14 can be pulled upwards, causing the sealing plates 14 to rotate under the support of the support shaft rod 13. When the two protective covers 15 come into contact with each other, the linkage rod 43 will be inserted into the linkage hole 44, thereby connecting the two sealing plates 14. After the two protective covers 15 are joined together, the sealing plates 14 are flipped downwards, causing the sealing plates 14 to completely cover the top of the cable pass-through housing 5, thus sealing the top of the cable pass-through housing 5. Then, with the help of a wrench, the transmission plate 27 is pressed downwards, causing the displacement rod 26 to move vertically under the support of the positioning plate 25, until the anti-rotation plate 30 moves out of the slot 3. 4. Move out to unlock the hollow shaft 22. At the same time, rotate the hollow shaft 22 with a wrench. With the connection between the hollow shaft 22 and the extension rod 23, the extension rod 23 can follow the rotation of the hollow shaft 22, driving the locking rod 24 to rotate towards the locking hole 8 until the locking rod 24 is inserted into the locking hole 8. Then separate the wrench from the transmission plate 27. When the transmission plate 27 is pressed down, the coil spring 28 will deform. Then, when the wrench is disengaged from the transmission plate 27, it can push the transmission plate 27 upward, so that the anti-rotation plate 30 is re-inserted into the slot 34, and finally lock the sealing plate 14 to prevent the sealing plate 14 from rotating uncontrollably. When the centralized cover 1 needs to be inspected and repaired, the locking rod 24 is disengaged from the locking hole 8, and then any one of the sealing plates 14 is pulled upwards, which will cause the two sealing plates 14 to flip synchronously, so as to expose the wire harness and centralized cover 1 inside the wire housing 5 for personnel to carry out inspection and repair work. When a protective cover 15 is damaged, the damaged protective cover 15 can be removed and replaced with a protective cover 15 of the same model.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
