[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.

[0050] As Figures 1-10 shown, it shows a seismic detector for three-dimensional seismic exploration in an embodiment of the present application,

[0051] In some examples, including:

[0052] The central cover 1 is fixedly connected with a magnet 2 at the bottom end inside the central cover 1, a mounting cylinder is sleeved on the outer side of the top end of the magnet 2, a coil 3 is wound on the outer side of the mounting cylinder, and a spring sheet 4 is arranged between the top end of the mounting cylinder and the central cover 1.

[0053] The wire passing shell 5 is provided with a lead cylinder 6 at the middle of each end, an extension seat 7 is fixedly connected to the inner wall of one end of the wire passing shell 5, and a lock hole 8 is formed at one end of the extension seat 7.

[0054] Two protection assemblies 9 are respectively assembled at the two ends of the wire passing shell 5, the protection assembly 9 is used for cooperating with the wire passing shell 5 to form protection of the central cover 1, and a plug 10 is arranged between the bottom ends of the two protection assemblies 9.

[0055] For example, as Figure 3 shown, an insulating ring 38 is arranged at the inner edge of the central cover 1, and a plurality of sealing rings 39 are fixedly connected to the outer side of the insulating ring 38.

[0056] In more detail, the material of the insulating ring 38 can be:

[0057] Polytetrafluoroethylene: a kind of high temperature resistant, chemical corrosion resistant material, with excellent insulation and low temperature aging resistance. It can still maintain softness and elasticity at low temperature;

[0058] Polyimide: a kind of high temperature resistant, chemical resistant thermoplastic polymer, with very good mechanical properties and insulation characteristics, which can still maintain its mechanical strength and elasticity at low temperature;

[0059] For example, as shown in Figure 5 Two protective components 9 each include:

[0060] The carrier frame 11 is slidingly connected to the bottom end of the wire passing shell 5, and the top of one end of the carrier frame 11 is fixedly connected with a positioning seat 12, the inner side of the positioning seat 12 is rotatably connected with a supporting shaft 13, and the outer side of the supporting shaft 13 is fixedly connected with a blocking plate 14 for blocking the top of the wire passing shell 5;

[0061] The protective cover 15 is fixedly connected to the bottom end of the carrier frame 11, and the protective 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;

[0062] The positioning strip 17 is fixedly connected to the edge of one side of one of the protective covers 15, and the end of the positioning strip 17 away from the protective cover 15 is fixedly connected with a clamping strip 18, the side of the other protective cover 15 close to the clamping strip 18 is provided with a quick mounting through slot 20, and the end of the quick mounting through slot 20 is provided with a quick mounting slot 19, and the clamping strip 18 is connected with the quick mounting slot 19 in a clamping manner;

[0063] The stop component 21 is assembled at one end of one of the blocking plates 14, and is used to cooperate with the lock hole 8 to form the normal locking of the blocking plate 14.

[0064] In this embodiment, the material of the protective cover 15 can be plastic, and the protective cover 15 can be deformed to a certain extent when the clamping strip 18 is extruded into the quick mounting slot 19, so that the clamping strip 18 can be clamped into the quick mounting slot 19;

[0065] For example, as shown in Figure 4 The bottom of one end of the wire passing shell 5 is fixedly connected with a guide strip 40, the end of the carrier frame 11 close to the guide strip 40 is provided with a guide groove 41, and the guide strip 40 is also slidingly connected in the inside of the guide groove 41.

[0066] In more detail, through the connection of the guide strip 40 and the guide groove 41, when the carrier frame 11 is connected with the wire passing shell 5, first, the guide strip 40 is corresponded with the guide groove 41, and the protective cover 15 is pushed, so that the carrier frame 11 is installed at the wire passing shell 5 in a sliding manner under the limiting of the guide strip 40;

[0067] For example, as shown in Figure 5 and Figure 7 One end of the other blocking plate 14 is fixedly connected with a linkage rod 43, one of the blocking plates 14 is provided with a linkage hole 44 near one end of the linkage rod 43, and the linkage rod 43 is also inserted and connected inside the linkage hole 44.

[0068] In more detail, through the structure cooperation of the linkage rod 43 and the linkage hole 44, when the two blocking plates 14 are close to each other, the linkage rod 43 will be inserted into the linkage hole 44, thereby realizing the linkage between the two blocking plates 14, and when any one of the blocking plates 14 is subsequently pulled, it can drive the two blocking plates 14 to flip synchronously.

[0069] In this embodiment, the edges of the bottom ends of the two blocking plates 14 and the edges of the sides close to each other are fixedly connected with sealing strips, and through the setting of the sealing strips, the gaps between the two blocking plates 14 and between the blocking plates 14 and the wire passing shell 5 can be blocked, so as to avoid water vapor and dust entering the wire passing shell 5 through the gaps.

[0070] For example, as shown in Figure 5 The interiors of the two protective covers 15 are fixedly connected with a plurality of retaining frames 42, and one end of each retaining frame 42 is provided with a non-slip pad.

[0071] In more detail, through the setting of the retaining frame 42, after the centralized cover 1 is installed, the centralized cover 1 can be assisted and supported by means of the retaining frame 42, so as to avoid uncontrollable movement of the centralized cover 1 after installation, and greatly ensure the stability of the application of the centralized cover 1.

[0072] For example, as shown in Figure 6 The clamping strip 18 and the quick mounting groove 19 are both circular structures, and the diameter of the clamping strip 18 is smaller than the width of the quick mounting through groove 20.

[0073] In more detail, through the structural characteristics of the clamping strip 18 and the quick mounting groove 19, when the clamping strip 18 contacts the quick mounting through groove 20, the protective cover 15 at the clamping strip 18 is continuously pushed, so as to extrude the quick mounting through groove 20 by means of the clamping strip 18, promote the quick mounting through groove 20 to deform, and until the clamping strip 18 moves into the quick mounting groove 19 through the quick mounting through groove 20. Since the clamping strip 18 moves into the quick mounting groove 19, the quick mounting through groove 20 will lose extrusion, and thus the blocking of the clamping strip 18 can be formed through the recovery of the quick mounting through groove 20.

[0074] For example, as shown in Figure 8 The stop component 21 includes:

[0075] A hollow shaft 22 is vertically rotatably connected to one end of one of the blocking plates 14. A extending 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 extending rod 23, and the locking rod 24 is connected with the lock hole 8.

[0076] A positioning piece 25 is fixedly connected to the middle of the hollow shaft 22. A displacement rod 26 is vertically slidably connected to the middle of the positioning piece 25. A transmission piece 27 is fixedly connected to the top end of the displacement rod 26. A helical spring 28 is fixedly connected between the top of the positioning piece 25 and the transmission piece 27.

[0077] A guide piece 29 is fixedly connected to the bottom end of the displacement rod 26. Four rotation-stopping clamping plates 30 are fixedly connected to the outer side of the guide piece 29. Four avoiding through grooves 31 are formed in the bottom end edge of the hollow shaft 22. The four rotation-stopping clamping plates 30 extend to the outside of the hollow shaft 22 through the four rotation-stopping clamping plates 30, respectively.

[0078] A limiting assembly is assembled at the bottom end of one of the blocking plates 14, and is used to cooperate with the rotation-stopping clamping plates 30 to form the normal rotation-stopping limiting of the hollow shaft 22.

[0079] For example, as shown in Figure 10 The lock hole 8 and the locking rod 24 are both arc-shaped structures.

[0080] In more detail, through the structural characteristics of the lock hole 8 and the locking rod 24, in the process of the rotation of the locking rod 24 following the hollow shaft 22, the smooth connection of the locking rod 24 and the lock hole 8 can be realized in a screwing-in manner, and the stability of the connection of the locking rod 24 and the lock hole 8 can be ensured.

[0081] In this embodiment, an inner hexagonal groove is formed in the top end of the transmission piece 27. Through the arrangement of the inner hexagonal groove, the transmission piece 27 can be conveniently rotated by a person with the aid of a hexagonal wrench.

[0082] At the same time, in this embodiment, a sealing gasket is fixedly connected to the edge of the top end of the transmission piece 27. Through the arrangement of the sealing gasket, in the normal state of the transmission piece 27, the gap between the top end of the transmission piece 27 and the hollow shaft 22 will be blocked by the sealing gasket, so as to avoid the entry of water vapor and dust into the inside of the wire casing 5 through the connecting gap between the transmission piece 27 and the hollow shaft 22.

[0083] For example, as shown in Figure 8 The limiting assembly includes:

[0084] The stabilizing frame 32 is fixedly connected to the bottom end of one of the blocking plates 14, the bottom end of the stabilizing frame 32 is fixedly connected with a stabilizing disc 33, four clamping grooves 34 are formed in the edge of the bottom end of the stabilizing disc 33, and four rotation-stopping clamping plates 30 are clamped and connected in the four clamping grooves 34 respectively, and a limiting sliding groove 35 is formed in the top end of the stabilizing frame 32;

[0085] The limiting plate 36 is fixedly connected to one side of the hollow shaft 22 close to the limiting sliding groove 35, the bottom end of the limiting plate 36 is fixedly connected with a limiting rod 37, and the limiting rod 37 is further movably connected in the limiting sliding groove 35.

[0086] In the embodiment, the limiting sliding groove 35 is arc-shaped, and the angle at which the limiting rod 37 can move in the limiting sliding groove 35 is ninety degrees, through the connection of the limiting sliding groove 35 and the limiting rod 37, the maximum rotation angle of the hollow shaft 22 is not more than ninety degrees, and when the limiting rod 37 is blocked by the limiting sliding groove 35, it can be fed back that the extension rod 23 is rotated to the specified position, so as to remind the personnel to lock the rod 24 has been connected or has been separated;

[0087] In the embodiment, the included angle between the two adjacent clamping grooves 34 is ninety degrees, so that after the hollow shaft 22 is rotated, the rotation-stopping clamping plate 30 can still correspond to the clamping groove 34, and the connection stability of the rotation-stopping clamping plate 30 and the clamping groove 34 is ensured;

[0088] Working principle: first, the guide grooves 41 at the two bearing frames 11 correspond to the two ends of the guide strip 40 respectively, and the plug 10 is placed between the two mounting grooves 16, then the protective cover 15 is pushed, the two bearing frames 11 are pushed towards each other along the guide strip 40, until the clamping strip 18 contacts with the quick-mounting through groove 20, then the two protective covers 15 are pushed at the same time, so that the quick-mounting through groove 20 is expanded by the clamping strip 18, until the clamping strip 18 passes through the quick-mounting through groove 20 and reaches the inside of the quick-mounting groove 19, when the clamping strip 18 reaches the quick-mounting groove 19, the quick-mounting through groove 20 loses the extrusion, and then the clamping strip 18 can be clamped in the quick-mounting groove 19 through the recovery of the quick-mounting through groove 20, so that the positioning of the plug 10 is formed by the mounting groove 16 while the two protective covers 15 are assembled;

[0089] The central cover 1 is installed between the two protective covers 15, and the wire harness of the central cover 1 is led out through the lead-in cylinder 6, and then the plug 10 is inserted into the designated detection position. In the embodiment, the magnet 2 has strong magnetism, the coil 3 is wound on the mounting cylinder by copper enameled wire, and has two output ends, the spring sheet 4 is made of special phosphor bronze and has a linear elastic coefficient, which connects the coil 3 and the central cover 1 together, and makes the coil 3 and the central cover 1 form a relative motion body. When the ground exists mechanical vibration, the coil 3 cuts the magnetic lines of force relative to the magnet 2, according to the principle of electromagnetic induction, an induced electromotive force is generated in the coil 3, and the size of the induced electromotive force is proportional to the relative motion speed of the coil 3 and the magnet 2. The analog electric signal output by the coil 3 is consistent with the speed change law of the ground mechanical vibration, so that three-dimensional seismic exploration is realized.

[0090] And for the plugging of the top end of the wire passing shell 5, the two plugging plates 14 can be pulled upwards before the two protective covers 15 contact each other, so that the plugging plates 14 rotate under the support of the support shaft 13. When the two protective covers 15 contact each other, the linkage rod 43 is inserted into the linkage hole 44, so as to connect the two plugging plates 14. When the two protective covers 15 are combined, the plugging plates 14 are turned down, so that the plugging plates 14 completely cover the top end of the wire passing shell 5, so as to plug the top end of the wire passing shell 5 through the plugging plates 14. Then, the wrench is pressed downward to drive the transmission sheet 27, so that the displacement rod 26 vertically displaces under the support of the positioning sheet 25 until the rotation stopping clamping plate 30 moves out of the clamping groove 34, so as to unlock the hollow shaft 22. At the same time, the wrench is used to rotate the hollow shaft 22, so that the extension rod 23 can rotate with the hollow shaft 22 under the connection of the hollow shaft 22 and the extension rod 23, and drives the locking rod 24 to rotate to the direction of the locking hole 8 until the locking rod 24 is clamped into the locking hole 8. Then, the wrench is separated from the transmission sheet 27. Since the transmission sheet 27 is pressed downward, the spiral spring 28 is deformed, and then when the wrench is separated from the transmission sheet 27, the transmission sheet 27 is pushed upward, so that the rotation stopping clamping plate 30 is clamped into the clamping groove 34 again, so as to lock the plugging plates 14 and prevent the plugging plates 14 from rotating uncontrollably.

[0091] When the central cover 1 needs to be maintained subsequently, the locking rod 24 is separated from the locking hole 8, and then any one of the plugging plates 14 is pulled upwards, so as to drive the two plugging plates 14 to flip synchronously, so as to expose the wire harness in the wire passing shell 5 and the central cover 1, so as to facilitate the maintenance work of personnel. When one of the protective covers 15 is damaged, the damaged protective cover 15 is removed and replaced with the same type of protective cover 15.

[0092] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
