Description

Technical Field

[0001] This utility model relates to the technical field of geological structure detection devices, specifically, to a geological structure detection device based on drilling and seismic detection. Background Technology

[0002] Abroad, as early as 1936, Weatherby proposed the idea of ​​using drill bit vibration as a seismic source to image underground structures. Since the 1980s, Seismic While Drilling (SWD) has gradually developed. In the 1990s, SWD transitioned from theoretical exploration to engineering applications, forming a complete set of technologies and beginning to provide services. These systems are still being continuously improved. It uses the vibration generated by the drill bit breaking rock during drilling operations as an underground seismic source. Sensors installed on the derrick and drill pipe top collect the drill bit vibration signals transmitted from the drill pipe, and detectors on the ground survey line collect the direct and reflected wave maps of the drill bit signals propagating through the formation. This allows for real-time prediction of details of the formation structure ahead of the drill bit, abnormal formation pore fluid pressure, and reduced drilling risks.

[0003] Currently, in geological exploration systems for drilling and seismic detection, the installation of sensors is particularly important. In existing technologies, sensors are mostly installed by mounting them on the mounting surface using mounting brackets. However, sensors are prone to falling off during long-term use, which affects their actual use. Utility Model Content

[0004] The purpose of this invention is to provide a geological structure detection device based on drilling and seismic detection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A geological structure detection device based on drilling and seismic detection includes a component sensor, which is mounted by a mounting assembly. The mounting assembly includes a mounting base with a mounting hole for inserting the component sensor, a limiting component for limiting the component sensor in the mounting hole, and a cooling component for cooling the component sensor in the mounting hole.

[0007] Furthermore, the mounting base has an annular groove along its circumference, and the top wall of the annular groove has a sliding groove that communicates with the mounting hole along the radial direction of the mounting base; the limiting component includes a drive ring rotatably disposed in the annular groove and a sliding block slidably disposed in the sliding groove. The side wall of the drive ring has an arc-shaped drive groove corresponding to the sliding block, and the sliding block has a drive post that slides in the drive groove. The drive ring rotates in both directions to drive one end of the sliding block to extend into or disengage from the mounting hole. The outer side wall of the component sensor has an insertion hole for one end of the corresponding sliding block to extend into.

[0008] Furthermore, the upper end of the mounting base is provided with a threaded column portion that fits over the component sensor. The upper side of the mounting base is provided with a strip groove that connects to the sliding groove along its radial direction. A slot is provided on the outer wall of the threaded column portion that connects to the corresponding strip groove. The sliding block is provided with a locking pin that passes through the strip groove and can be locked into the slot. A plug cap for limiting the locking pin to the slot is connected to the external thread of the threaded column portion.

[0009] Furthermore, the outer wall of the component sensor is provided with a mounting ring that overlaps the top of the threaded column, and the mounting ring is fixed to the top of the threaded column by screws.

[0010] Furthermore, a cooling chamber is provided circumferentially within the mounting base, and the cooling assembly includes a cooling pipe located outside the mounting base and communicating with the cooling chamber, the cooling pipe being used to allow coolant to flow through the cooling chamber.

[0011] Furthermore, the outer wall of the mounting base is provided with heat-conducting fins extending into the cooling cavity along its circumference, and multiple heat-conducting fins are arranged.

[0014] 1. In this utility model, by setting a limiting component, the limiting component can limit the component sensor when it is inserted into the mounting hole, thereby preventing the component sensor from detaching from the mounting base during long-term use and affecting the use of the component sensor.

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0026] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0027] like Figure 1As shown, this embodiment of a geological structure detection device based on drill-and-surge seismic analysis includes a component sensor 100, which is installed using mounting components. It also includes a geophone and an explosion-proof geological sidewall detector main unit. Specifically, the geophone, component sensor 100, and explosion-proof geological sidewall detector main unit all adopt the structure described in announcement number CN104749637B. The geophone is placed at the tail end of the drill string to receive the waves emitted by the drill bit; the component sensor 100 group is placed on the sidewall of the tunnel, and the component sensor 100 can simultaneously detect direct waves and reflected waves; when the drilling rig is started, the geophone transmits the vibration signal transmitted by the drill bit source through the drill string via... The wireless transmission module sends data to the host of the explosion-proof geological sidewall detector. The component sensor 100 transmits the received direct wave and / or reflected wave to the host of the explosion-proof geological sidewall detector via the wireless transmission module. The host of the explosion-proof geological sidewall detector analyzes and processes the received data. Therefore, in this embodiment, the vibration generated by the drill bit breaking rock during drilling operations is used as an underground seismic source. The component sensor 100 collects the drill bit vibration signal transmitted from the drill pipe, and the component sensor 100 installed on the sidewall of the roadway simultaneously detects the direct wave and reflected wave of the drill bit signal propagating through the strata. This allows for real-time prediction of the details of the strata structure ahead of the drill bit and prediction of abnormal strata pore fluid pressure.

[0028] Combination Figure 2 As shown, in this embodiment, the mounting assembly includes a mounting base 110, which has a mounting hole 200 for inserting a component sensor 100, and a limiting component for limiting the component sensor 100 in the mounting hole 200. The mounting base 110 also has a cooling component for cooling the component sensor 100 in the mounting hole 200.

[0029] In this embodiment, the mounting base 110 is disc-shaped, and its bottom wall extends outward to form a flange 111, so that in actual use, the flange 111 is fixedly installed on the roadway sidewall, derrick and drill pipe top and other mounting surfaces by bolts, thereby realizing the fixed installation of the mounting base 110.

[0030] The component sensor 100 is inserted into the mounting hole 200 by setting the mounting hole 200, so that the component sensor 100 can be installed and removed from the mounting base 110.

[0031] In this embodiment, by setting the limiting component, when the component sensor 100 is installed in the mounting hole 200, the limiting component can limit the component sensor 100, thereby preventing the component sensor 100 from detaching from the mounting base 110 during long-term use. That is, the component sensor 100 installed on the mounting base 110 is not easy to detach, which is beneficial to the actual use of the component sensor 100.

[0032] The cooling component allows the component sensor 100 to be cooled down when the ambient temperature is high, ensuring its normal operation.

[0033] Combination Figure 3 and Figure 4 As shown, in this embodiment, the mounting base 110 has an annular groove 201 along its circumference, and the top wall of the annular groove 201 has a sliding groove 202 that communicates with the mounting hole 200 along the radial direction of the mounting base 110; the limiting component includes a drive ring 210 rotatably disposed in the annular groove 201 and a sliding block 220 slidably disposed in the sliding groove 202. The side wall of the drive ring 210 has an arc-shaped drive groove 301 corresponding to the sliding block 220. The sliding block 220 has a drive post 311 that slides in the drive groove 301. The drive ring 210 rotates in both directions to drive one end of the sliding block 220 to extend into or out of the mounting hole 200. The outer side wall of the component sensor 100 has an insertion hole for one end of the corresponding sliding block 220 to extend into.

[0034] In practical use, to facilitate the installation of the limiting component within the mounting base 110, the opening of the annular groove 201 faces upwards, and a cover plate 320 is welded to its opening. A sliding groove 202 is radially disposed along the mounting base 110 on the lower end face of the cover plate 320. When the cover plate 320 is installed on the mounting base 110, it presses the drive ring 210 into the annular groove 201, while simultaneously limiting the sliding block 220 within the sliding groove 202. The arrangement of the drive groove 301 and the drive post 311 ensures that the drive ring 210 is positioned within the annular groove 201. The forward and reverse rotation within 01 causes the sidewall of the drive groove 301 to press against the drive column 311, thereby driving the sliding block 220 to extend and retract within the drive groove 301. This controls the sliding block 220 to extend into or out of the mounting hole 200. When the sliding block 220 extends into the mounting hole 200 and is inserted into the insertion hole, it limits the component sensor 100 inserted into the mounting hole 200. When the sliding block 220 retracts into the sliding groove 202, it disengages from the insertion hole, releasing the limitation on the component sensor 100, thus facilitating the installation and removal of the component sensor 100 from the mounting base 110.

[0035] Specifically, in order to facilitate the operator to drive the drive ring 210 to rotate outside the mounting base 110, in this embodiment, the outer side wall of the mounting base 110 is provided with a notch 331 that communicates with the drive groove 301, and the side wall of the drive ring 210 is provided with a lever 302 that extends out of the notch 331. Thus, the operator can drive the drive ring 210 to rotate forward and backward by moving the lever 302.

[0036] It should be noted that, in order to ensure that the insertion hole and the corresponding sliding block 220 are aligned, in this embodiment, a limiting groove is formed on the side wall of the mounting hole 200 along its axial direction, and a limiting block is provided on the outer side wall of the component sensor 100, which slides in the limiting groove. Thus, during actual insertion and installation, the limiting block is aligned with the limiting groove, and the component sensor 100 is inserted into the mounting hole 200 so that when the component sensor 100 abuts against the bottom wall of the mounting hole 200, the insertion hole and the corresponding sliding block 220 are aligned, so that the limiting component can be used.

[0037] In this embodiment, the upper end of the mounting base 110 is provided with a threaded post 203 that fits over the component sensor 100. The upper side of the mounting base 110 is provided with a strip groove 321 that connects to the sliding groove 202 along its radial direction. The outer side wall of the threaded post 203 is provided with a slot 322 that connects to the corresponding strip groove 321. The sliding block 220 is provided with a locking post 312 that penetrates the strip groove 321 and can be locked into the slot 322. The threaded post 203 is externally threaded with a plug cap 120 for limiting the locking post 312 in the slot 322.

[0038] In practical use, the threaded post 203 is integrally formed on the upper surface of the cover plate 320. Through this structure, turning the plug cap 120 upwards along the threaded post 203 allows the slot 322 to be exposed. At this time, when one end of the sliding block 220 extends into the mounting hole 200 to limit the component sensor 100, the locking post 312 slides along the strip groove 321 into the slot 322. Turning the plug cap 120 downwards along the threaded post 203 then seals the slot 322, thus limiting the locking post 312 within the slot 322, locking the sliding block 220 and ensuring it always limits the component sensor 100. When it is necessary to release the limitation on the component sensor 100, turning the plug cap 120 upwards along the threaded post 203 allows the slot 322 to be exposed, and the drive ring 210 can be rotated forward and backward by the lever 302. The operation is simple and convenient.

[0039] In this embodiment, in order to fix the component sensor 100 inserted into the mounting hole 200, a mounting ring 230 is provided on the outer wall of the component sensor 100, which overlaps the top end of the threaded post 203. The mounting ring 230 is fixed to the top end of the threaded post 203 by screws, thereby fixing the component sensor 100 inserted into the mounting hole 200. In actual use, the plug cap 120 slides around the component sensor 100. When the plug cap 120 is threaded to the outside of the threaded post 203, it can cover the mounting ring 230 to protect it.

[0040] Combination Figure 5As shown, in this embodiment, a cooling cavity 204 is provided in the mounting base 110 along its circumference. The cooling assembly includes a cooling pipe 130 located outside the mounting base 110 and communicating with the cooling cavity 204. The cooling pipe 130 is used to allow coolant to flow through the cooling cavity 204.

[0041] In this embodiment, the cooling pipe 130 includes a coolant inlet pipe and a coolant outlet pipe, thereby enabling coolant to flow through the cooling chamber 204 through the cooling pipe 130 when the ambient temperature is too high. The mounting base 110 is made of a thermally conductive material, so the coolant flowing in the cooling chamber 204 can absorb the heat on the component sensor 100 through the mounting base 110 to achieve a cooling effect, thereby ensuring the use of the component sensor 100.

[0042] In this embodiment, the outer side wall of the mounting base 110 is provided with heat-conducting fins 140 extending into the cooling cavity 204 along its circumference. Multiple heat-conducting fins 140 are arranged, and the heat-conducting fins 140 are made of heat-conducting material. They can conduct heat from the coolant in the cooling cavity 204 out of the mounting base 110 and dissipate it, thereby improving the cooling effect of the coolant on the component sensor 100.

[0043] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
