Abstract
Description
Technical Field
[0001] This invention relates to the field of geological prediction technology, specifically to a geological prediction detector and its installation auxiliary equipment. Background Technology
[0002] A geophone is a device that detects useful information from seismic waves. In tunnel engineering, geophones are installed by drilling holes behind the tunnel face, and shot points are set behind the geophones as seismic sources. By detecting seismic waves with the geophones, signal recorders can record the corresponding signals, which technicians can then use to analyze the geological conditions ahead.
[0003] Before installation, a coupling agent such as mud or grease needs to be inserted into the borehole to tightly couple the detector to the surrounding rock. However, poor coupling may cause the detector and coupling agent to loosen, affecting the detector's reception of seismic wave signals and ultimately impacting geological prediction results. Therefore, we propose a geological prediction detector and its installation auxiliary equipment. Summary of the Invention
[0004] (i) In view of the shortcomings of the prior art, the present invention provides a geological prediction detector and its installation auxiliary equipment, which overcomes the problem of loosening between the detector and the coupling agent in the prior art, ensures the reception of seismic wave signals, and ensures the accuracy of geological prediction results.
[0005] (II) To achieve the above objectives, the present invention is implemented through the following technical solution: a geological prediction detector, comprising a detector body and a communication cable, wherein the detector body is connected to a signal splitter via the communication cable, and the signal splitter is connected to a signal recorder via the communication cable.
[0006] The present invention also provides an auxiliary device for installing a geological prediction geophone. The auxiliary device includes an expansion mechanism for stably supporting the geophone body. The expansion mechanism includes a sleeve for mounting the geophone body. The sleeve has a notch and multiple annular airbags are used on the sleeve. Each of the multiple annular airbags is connected to a connecting hose. The other end of the multiple connecting hoses is connected to the same shunt hose. The other end of the shunt hose is connected to a connector. The connector is connected to a pressure relief pipe with a sealing cap. The auxiliary device also includes a compression section for inflation.
[0007] The compression unit includes a pedal and a circular shell. A compression airbag and multiple elastic telescopic rods are installed between the pedal and the circular shell. An air inlet pipe with a one-way valve is connected to the circular shell, and an inflation pipe with a one-way valve is also connected to the circular shell. The inflation pipe and the connector are threaded together. A filter cartridge is threaded onto the air inlet pipe.
[0008] Preferably, a quick-connect mechanism for communication is provided between the connector and the inflation tube. The quick-connect mechanism includes a sealing ring fixed inside the connector, a sealing plate abutting against the sealing ring, and two elastic telescopic rods symmetrically fixed on the sealing plate. The two elastic telescopic rods are installed inside the connector, and a push rod for opening the sealing plate is fixed inside the inflation tube. A support block is also provided between the two elastic telescopic rods and the connector, and the support block is fixed inside the connector and fixed to the two elastic telescopic rods.
[0009] Preferably, the installation auxiliary equipment includes two sets of assemblable sealing mechanisms. Each set of sealing mechanisms includes a semi-connecting column, a semi-circular plug fixed on the semi-connecting column, and a semi-rotating handle fixed on the semi-circular plug. The semi-connecting column, the semi-circular plug, and the semi-rotating handle are provided with the same semi-wire hole.
[0010] Preferably, one set of the sealing mechanism has two positioning rods fixed on its half-rotating handle, and the other set of the sealing mechanism has positioning holes that are adapted to the positioning rods on its half-rotating handle.
[0011] Preferably, the installation auxiliary equipment further includes a mechanism for adsorbing and extracting the detector body. The extraction mechanism includes an extraction cylinder, one end of which is connected to a suction cup. A piston is slidably installed inside the extraction cylinder, and a rod is fixed to the piston and slidably installed with the extraction cylinder. A handle is fixed to the other end of the rod, and a locking part is provided between the rod and the extraction cylinder. The locking part includes a connecting rod slidably installed on the extraction cylinder. A pull plate is fixed to the top end of the connecting rod, and an arc-shaped locking block is fixed to the bottom end of the connecting rod. Multiple locking holes are provided on the rod to engage with the arc-shaped locking block. A fan-shaped hole is provided at the end of the extraction cylinder near the handle.
[0012] (III) The present invention provides a geological prediction detector and its installation auxiliary equipment, which has the following beneficial effects:
[0013] 1. By adding a geophone body and an expansion mechanism, when the tail cone of the geophone body abuts against the surrounding rock, the compression section is controlled to inflate the connector. The annular airbag inflates and begins to expand, which can stably support the casing in the channel. At this time, the geophone body abutting between the casing and the surrounding rock is also stably fixed, which can prevent the geophone body from loosening due to poor coupling effect, ensuring the reception of seismic wave signals and ensuring the accuracy of geological prediction results.
[0014] 2. By incorporating a quick-connect mechanism, the detachable design eliminates the need for a separate airbag and its associated components at each connector, reducing costs and simplifying operation.
[0015] 3. By adding a sealing mechanism, the two sets of sealing mechanisms are assembled and pressed tightly against the orifice to seal the orifice. There is no need to use yellow mud for sealing, and there is no need to clean the yellow mud adhering to the communication cable and the shunt hose later. The operation is also more convenient.
[0016] 4. By adding an extraction mechanism, the suction cup is attached to the detector body. Technicians can pull out the sleeve and extraction cylinder together to remove the detector body without causing wear or damage to the detector body or damaging the communication cable, thus extending its service life.
[0017] 5. By adding a snap-fit part, after the pull rod is pulled out to a suitable distance, the arc-shaped snap-fit block will snap into the snap-fit hole. Even if the technician releases his hand, the pull rod will not move back, making it convenient for the technician to pull out the sleeve and the extraction cylinder at the same time by hand, which is more convenient to operate.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0036] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0037] Example 1
[0038] like Figure 2As shown, a geological prediction detector includes a detector body 1a and a communication cable 1d. The detector body 1a is connected to a signal splitter 1b via the communication cable 1d, and the signal splitter 1b is connected to a signal recorder 1c via the communication cable 1d. Before installing the detector body 1a, multiple channels are drilled on the rear side of the working face. After inserting the detector body 1a into the channels, a coupling agent, such as mud or grease, is used to tightly couple the detector body 1a to the surrounding rock. The seismic source is located on the rear side of the detector body 1a. After the seismic source vibrates, the detector body 1a detects the seismic waves, and the corresponding signals are recorded by the signal recorder 1c.
[0039] Example 2
[0040] like Figures 1-5 As shown, an auxiliary device for installing a geological prediction geophone includes an expansion mechanism 2 for stabilizing and supporting the geophone body 1a. The expansion mechanism 2 includes a sleeve 21 for mounting the geophone body 1a. The sleeve 21 has a notch 22 with an arc-shaped edge to prevent cutting the connecting hose 24. The sleeve 21 is equipped with multiple annular airbags 25, each connected to a connecting hose 24. The other end of the multiple connecting hoses 24 is connected to the same diversion hose 23. The other end of the diversion hose 23 is connected to a connector 26, which is connected to a pressure relief pipe 28 with a sealing cap. The auxiliary device also includes a compression section 27 for inflation. First, coupling agent is inserted into the corresponding channel. Then, the detector body 1a is inserted into one end of the sleeve 21, and the communication cable 1d connected to the detector body 1a is located inside the sleeve 21. Next, the annular airbag 25 is fitted onto the outer surface of the sleeve 21, and the connecting hose 24 connected to the annular airbag 25 is positioned on the notch 22. The shunt hose 23 connected to the connecting hose 24 is located inside the sleeve 21. Then, the sleeve 21 is inserted into the channel until it cannot be inserted any further. At this point, the tail cone of the detector body 1a abuts against the surrounding rock. Then, the compression section 27 is controlled to inflate the connector 26 with air. The gas enters the diversion hose 23 through the connector 26. The gas is diverted by the connecting hose 24 into the annular airbag 25. The annular airbag 25 is inflated and begins to expand until the outer surface of the annular airbag 25 is pressed against the channel. At the same time, the inner surface of the annular airbag 25 is pressed against the outer surface of the casing 21, thus firmly supporting the casing 21 in the channel. At this time, the geophone body 1a, which is pressed against the casing 21 and the surrounding rock, is also firmly fixed, preventing the geophone body 1a from loosening due to poor coupling effect, ensuring the reception of seismic wave signals and ensuring the accuracy of the detection results.
[0041] When the detection is complete and the detector body 1a needs to be removed, the sealing cap on the pressure relief pipe 28 can be opened. After the gas in the annular airbag 25 is discharged, the sleeve 21 and the detector body 1a can be removed.
[0042] The compression unit 27 includes a pedal 271 and a circular shell 273. A compression airbag 274 and a plurality of elastic telescopic rods 272 are installed between the pedal 271 and the circular shell 273. An air inlet pipe 275 with a one-way valve is connected to the circular shell 273, and an inflation pipe 276 with a one-way valve is connected to the circular shell 273. The inflation pipe 276 and the connector 26 are threaded together. During inflation, the foot pedal 271 is pressed, compressing the air bladder 274 and allowing the gas inside to escape through the inflation tube 276 and enter the connector 26 (during this process, one-way valve one is closed and one-way valve two is open). When the foot pedal 271 is released, under the elastic force of the elastic telescopic rod 272, the foot pedal 271 moves upward, and outside air enters the air bladder 274 through the air inlet tube 275, causing the air bladder 274 to expand (during this process, one-way valve one is open and one-way valve two is closed). Technicians can repeatedly press the foot pedal 271 to inflate the connector 26, making the operation quite convenient.
[0043] In this embodiment, a filter cartridge 29 is threaded onto the air intake pipe 275. The filter cartridge 29 is designed to filter the incoming air and prevent impurities from entering and clogging the pipe.
[0044] Example 3
[0045] refer to Figures 6-8 Based on embodiment 2, a quick-connect mechanism 4 for communication is provided between the connector 26 and the inflation tube 276. The quick-connect mechanism 4 includes a sealing ring 41 fixed inside the connector 26, a sealing plate 42 abutting against the sealing ring 41, and elastic telescopic rods 43 symmetrically fixed on the sealing plate 42. The elastic telescopic rods 43 are installed inside the connector 26. Specifically, a support block 44 is also provided between the elastic telescopic rods 43 and the connector 26. The support block 44 is fixed inside the connector 26 and is fixed to the elastic telescopic rods 43. A push rod 45 for opening the sealing plate 42 is fixed inside the inflation tube 276. When the sleeve 21 and the detector body 1a on it in one of the channels are pressed together, the connector 26 can be rotated to detach the connector 26 from the air filling tube 276. During this process, the push rod 45 gradually separates from the sealing plate 42. Under the elastic force of the elastic telescopic rod 43, the sealing plate 42 moves and abuts against the sealing ring 41 to prevent the filled gas from leaking out from the connector 26.
[0046] At this point, technicians can use the components detached from connector 26 (including pedal 271, elastic telescopic rod 272, air bladder 274, round shell 273, air inlet pipe 275, inflation pipe 276, and push rod 45) on connector 26 in other channels. The specific method is as follows: thread connector 26 from other channels onto inflation pipe 276. During tightening, push rod 45 gradually penetrates and pushes open sealing plate 42, separating sealing plate 42 from sealing ring 41, thus connecting connector 26 to inflation pipe 276. This eliminates the need for a separate air bladder 274 and its connected components on each connector 26, reducing costs and simplifying operation.
[0047] Example 4
[0048] After the detector body 1a is installed, the opening of the channel needs to be sealed with yellow mud to prevent the fluctuations in the tunnel from affecting the detection of the detector body 1a.
[0049] refer to Figures 9-12 Based on embodiment 3, the installation auxiliary equipment includes two sets of assemblable sealing mechanisms 3. Each sealing mechanism 3 includes a semi-connecting post 31, a semi-circular plug 32 fixed on the semi-connecting post 31, and a semi-rotating handle 33 fixed on the semi-circular plug 32. The semi-connecting post 31, the semi-circular plug 32, and the semi-rotating handle 33 are provided with the same semi-wire hole 34. When the two sets of sealing mechanisms 3 are assembled (e.g....), Figure 10 As shown, the two half-connecting posts 31 can be threaded onto the sleeve 21. By continuously rotating the handle 33, the frustum plug part extends into the channel until the frustum plug is pressed against the opening of the channel. At this time, the shunt hose 2 and the communication cable 14 pass through the wire hole, thus sealing the opening. There is no need to use yellow mud for sealing, and there is no need to clean the yellow mud adhering to the communication cable 1d and the shunt hose 2 later. The operation is also more convenient.
[0050] Furthermore, two positioning rods 36 are fixed on the semi-rotating handle 33 of one set of sealing mechanisms 3, and positioning holes 35 that are adapted to the positioning rods 36 are opened on the semi-rotating handle 33 of the other set of sealing mechanisms 3. During assembly, the positioning rods 36 can be inserted into the corresponding positioning holes 35, and the two sets of sealing mechanisms 3 can be assembled together. The positioning method makes the assembly more convenient.
[0051] Example 5
[0052] Traditionally, when removing a detector, the cable connected to the detector is often pulled outwards, which can easily damage the detector. Moreover, when the detector is pulled out, it will rub against the channel, which will also cause wear and tear on the detector.
[0053] refer to Figures 13-16Based on Embodiment 4, the installation auxiliary equipment further includes an extraction mechanism 5 for adsorbing the detector body 1a. The extraction mechanism 5 includes an extraction cylinder 51. Specifically, a fan-shaped hole is provided at one end of the extraction cylinder 51 near the handle 55. A suction cup 52 is connected to one end of the extraction cylinder 51, and a piston 53 is slidably installed inside the extraction cylinder 51. A pull rod 54 is fixed on the piston 53 and slidably installed with the extraction cylinder 51. The handle 55 is fixed at the other end of the pull rod 54, and a locking part 56 is provided between the pull rod 54 and the extraction cylinder 51. After the detection is completed, the gas in the annular airbag 25 is released and the sealing mechanism 3 is removed. The shunt hose 2 and the communication cable 14 are straightened, and the extraction mechanism 5 is inserted into the sleeve 21 until the suction cup 52 is pressed against the detector body 1a. At this time, the extraction cylinder 51 is held and the extraction rod 54 is pulled outward, which drives the piston 53 to move outward. The suction cup 52 can then be tightly attached to the detector body 1a. At this time, the locking part 56 locks and fixes the extraction rod 54 and the extraction cylinder 51. Then, the technician can pull out the sleeve 21 and the extraction cylinder 51 together, which can take out the detector body 1a without wear or damage to the detector body 1a or damage to the communication cable 1d, thus extending its service life.
[0054] Furthermore, the locking part 56 includes a connecting rod 562 slidably mounted on the extraction cylinder 51. A pull plate 563 is fixed to the top of the connecting rod 562, and an arc-shaped locking block 564 is fixed to the bottom of the connecting rod 562. The pull rod 54 has multiple locking holes 561 that engage with the arc-shaped locking block 564. When the pull rod 54 is pulled outward, after being pulled out to a suitable distance, the arc-shaped locking block 564 will engage in the locking hole 561 under the action of gravity. This prevents the pull rod 54 from shifting back due to negative pressure when the technician releases his hand, which would cause the suction cup 52 to fail to firmly adhere to the detector body 1a. Even if the technician releases his hand, the pull rod 54 will not shift back, making it convenient for the technician to pull out the sleeve 21 and the extraction cylinder 51 together by hand, making the operation more convenient.
