Description

Technical Field

[0001] The invention belongs to the technical field of formation wave velocity testing and vibration monitoring in civil engineering, mining and traffic engineering, and specifically relates to a recyclable installation device and an installation method for an in-hole vibration sensor. Background Art

[0002] In civil engineering, mining and transportation engineering, formation wave velocity testing and vibration monitoring can obtain parameters such as wave velocity, vibration frequency and amplitude of formation rock and soil. These parameters are crucial for evaluating the mechanical properties, stiffness and elastic modulus of rock and soil. Accurately obtaining these parameters can provide a basis for engineering design and geological disaster risk warning.

[0003] In the process of implementing formation wave velocity testing and rock and soil vibration monitoring, the installation method of the sensor is crucial to the accuracy and practicality of data collection. Traditional in-hole sensor installation mostly uses pouring curing agent for permanent installation, which not only increases the workload, the number and cost of sensors, but also limits the reuse and flexibility of mobile installation of sensors. In addition, when installing traditional in-hole sensors, the drilled holes used generally do not have casings, which can easily cause problems such as hole collapse, diameter reduction, or loose pouring of curing agent during sensor installation, making it impossible to install the sensor or causing abnormalities in the collected vibration data. In view of the many shortcomings of traditional vibration sensor installation technology, it is necessary to invent a recyclable and reliable installation device and method for in-hole vibration sensors. Summary of the invention

[0004] In order to solve the problems existing in the background technology, the purpose of the present invention is to provide a recyclable installation device and installation method for a vibration sensor in a hole. The hydraulic controller controls the push-out and retraction of the support sheet of the installation device, so that the vibration sensor and the borehole wall are in a coupling and detaching state, and the ring buckle on the installation device is used to protect the cable of the sensor; the sensor and the installation device can be recycled and reused, overcoming the shortcomings of the traditional vibration sensor installation technology.

[0005] The technical solution adopted by the present invention is as follows:

[0006] 1. A recyclable installation device for an in-hole vibration sensor:

[0007] It includes a hydraulic cabin, a support plate, a hydraulic system, a cover plate assembly and a telescopic assembly; the hydraulic cabin is a hollow cabin structure with openings at both ends, the hydraulic cabin is used to store hydraulic oil, and cover plate assemblies are installed at both ends of the hydraulic cabin, the two cover plate assemblies are symmetrically arranged at both ends with the vertical middle of the hydraulic cabin as the center, and the hydraulic cabin and the cover plate assembly are both connected to an external vibration sensor; the support plate can be movably connected to the side wall of the hydraulic cabin through the telescopic assembly, and the hydraulic system is connected to the hydraulic cabin for injecting or extracting hydraulic oil into the hydraulic cabin and then adjusting the oil pressure in the hydraulic cabin.

[0008] The telescopic assembly includes a piston, a connecting rod, a spring, a hydraulic connecting rod, a tooth pair and a limit plate; a piston hole and a connecting rod hole are spaced apart on one side of the hydraulic cabin, one end of the piston can be installed in the piston hole of the hydraulic cabin so as to be movable forward and backward along the radial direction of the hydraulic cabin, and the other end of the piston is fixedly connected to the support plate through a connecting rod; one end of the hydraulic connecting rod can be arranged in the connecting rod hole so as to be movable forward and backward along the radial direction of the hydraulic cabin, and the other end of the hydraulic connecting rod is fixedly connected to a tooth piece in the tooth pair; the other tooth piece in the tooth pair is fixedly connected to the support plate, the hydraulic connecting rod is arranged obliquely, and the tooth pair is arranged along the radial direction of the hydraulic cabin; the limit plate is located between the hydraulic connecting rod and a tooth piece of the tooth pair, and the limit plate is fixedly connected to the outer wall of the hydraulic cabin; the outer wall of the hydraulic cabin and the support plate are also connected by a spring that can be telescoped along the radial direction of the hydraulic cabin.

[0009] The cover plate assembly includes a threaded column, a ring and a nut; a threaded column is installed at the opening position of the end of the cover plate assembly, and a ring is connected to the side of the threaded column close to the hydraulic cabin through a nut, and the ring is connected to the cable of the vibration sensor; the hydraulic system includes a hydraulic pipe and a hydraulic controller; one side of the threaded column is connected to the hydraulic controller through the hydraulic pipe; the hydraulic controller adjusts the oil pressure in the hydraulic cabin through the hydraulic pipe and the threaded column.

[0010] The latching tooth pair is composed of two latching tooth pieces, each of which is provided with a latching tooth structure arranged in a row, and the two latching tooth pieces are symmetrically arranged up and down, so that the latching tooth structures in the two latching tooth pieces can be connected by latching;

[0011] When the oil pressure in the hydraulic chamber increases, the hydraulic connecting rod extends outward, thereby driving one of the latching teeth in the latching teeth pair to move, and causing the two latching teeth in the latching teeth pair to disengage; at the same time, the piston extends outward as the oil pressure increases, driving the support sheet to be pushed outward;

[0012] When the oil pressure in the hydraulic chamber decreases, the hydraulic connecting rod retracts inward, thereby driving one of the latching teeth to move synchronously; at the same time, the piston retracts inward as the oil pressure decreases, driving the support plate and the other latching tooth to retract inward, and the two latching teeth contact and close and lock. The vibration sensor and the support plate are located on both sides of the hydraulic chamber in the radial direction.

[0013] A fin is connected to the side of the hydraulic cabin away from the telescopic assembly, and the fin is arranged along the axial direction of the hydraulic cabin; a plurality of fixing holes are opened on the fin, and the vibration sensor is connected to the side wall of the hydraulic cabin through the fin.

[0014] The installation device includes two telescopic components, through which the support plate can be connected to the side wall of the hydraulic cabin so as to move forward and backward along the radial direction of the hydraulic cabin. The two telescopic components are symmetrically arranged at both ends with the vertical middle of the hydraulic cabin as the center.

[0015] The hydraulic cabin shell and the support plate are both made of metal materials. The compressive strength of the hydraulic cabin shell material is not less than 200 MPa, and the bending strength of the support plate material is not less than 200 MPa.

[0016] 2. A recyclable installation method for an in-hole vibration sensor comprises the following steps:

[0017] Step 1: First, manually press the support sheet inwards, and after the support sheet compresses the spring, the two latching teeth in the latching teeth are closed and locked, so that the distance between the support sheet and the outer wall of the hydraulic chamber reaches the distance threshold;

[0018] Step 2: Connect the threaded column at one end of the hydraulic cabin to the hydraulic controller through the hydraulic pipe, point the threaded column at the other end of the hydraulic cabin upward, start the hydraulic controller, and inject hydraulic oil into the hydraulic cabin. When the hydraulic oil begins to overflow from the threaded column at the lower end of the hydraulic cabin, turn off the hydraulic controller and seal the threaded column at the lower end of the hydraulic cabin to prevent the hydraulic oil from leaking out.

[0019] Step 3: Start the hydraulic controller, apply oil pressure to the hydraulic compartment and stabilize the pressure for 10 minutes, and observe whether the oil pressure value displayed by the hydraulic controller is stable:

[0020] If the oil pressure value is stable, it means that the installation device is well sealed;

[0021] If the oil pressure value decreases, it indicates that there is leakage at the threaded column position at the end of the hydraulic compartment. Refill the hydraulic oil and seal the threaded column until the installation device is well sealed;

[0022] Step 4: Manually press the support sheet inward again so that the distance between the support sheet and the outer wall of the hydraulic compartment reaches the distance threshold; place the vibration sensor close to the fin on the side wall of the hydraulic compartment, and use a wire tie to pass through the fixing hole on the fin to fix the vibration sensor to the fin;

[0023] Step 5: Connect the cable of the vibration sensor to the ring buckle, and adjust the position of the fixed end of the ring buckle so that the outer edge of the ring buckle does not exceed the outer edge of the vibration sensor;

[0024] Step 6: Lower the vibration sensor and the installation device along the borehole to the target position, turn on the hydraulic controller, apply oil pressure to the hydraulic cabin, and the hydraulic connecting rod extends outward, thereby driving one of the toothed pieces in the tooth pair to move, so that the two toothed pieces in the tooth pair are disengaged; at the same time, the piston extends outward as the oil pressure increases, and the spring also pops outward, driving the support plate to move toward one side of the borehole wall; the telescopic assembly drives the vibration sensor and the hydraulic cabin to move toward the other side of the borehole wall until the support plate and the vibration sensor are both in close contact with the borehole wall, and the vibration sensor is fixed in the borehole;

[0025] Step 7: Next, close the hydraulic controller, and under the outward thrust of the spring, the vibration sensor is fixedly coupled to the borehole wall;

[0026] Step 8. Open the hydraulic controller and pump back the hydraulic oil in the hydraulic cabin. The hydraulic connecting rod retracts inward, thereby driving one of the gear pieces in the gear pair to move. At the same time, the piston retracts inward as the oil pressure decreases, driving the support plate and the other gear piece to retract inward. The two gear pieces come into contact and close and lock, and the spring is compressed. After the vibration sensor falls off from the borehole wall, lift the vibration sensor and the installation device out of the borehole, and recover the vibration sensor and the installation device.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The installation device of the present invention uses a hydraulic control system to change the working state of the support plate, thereby achieving rapid coupling or separation between the vibration sensor and the borehole wall, and improving the signal collection quality.

[0029] 2. The installation device of the present invention uses a buckle to fix the cable, thereby preventing the cable from being damaged when the vibration sensor is coupled to the hole wall, thereby achieving protection of the vibration sensor cable.

[0030] 3. The installation device of the present invention is simple and convenient to operate, and can realize the recovery and reuse of the vibration sensor and the installation device, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1-Figure 2 As shown, the device includes a hydraulic cabin 1, a support plate 4, a hydraulic system, a cover plate assembly and a telescopic assembly; the hydraulic cabin 1 is a hollow cabin structure with openings at both ends, the hydraulic cabin 1 is used to store hydraulic oil, and cover plate assemblies are installed at the upper and lower ends of the hydraulic cabin 1.

[0039] The telescopic assembly includes a piston 2, a connecting rod 3, a spring 5, a hydraulic connecting rod 7, a tooth pair 8 and a limit plate 9; a piston hole and a connecting rod hole are provided at intervals on one side of the hydraulic cabin 1, one end of the piston 2 can be installed in the piston hole of the hydraulic cabin 1 so as to be movable forward and backward along the radial direction of the hydraulic cabin 1, and the other end of the piston 2 is fixedly connected to the support plate 4 through the connecting rod 3; one end of the hydraulic connecting rod 7 can be arranged in the connecting rod hole 6 so as to be movable forward and backward along the radial direction of the hydraulic cabin 1, and the other end of the hydraulic connecting rod 7 is fixedly connected to a tooth piece in the tooth pair 8, and the tooth piece is connected to the side wall of the hydraulic cabin 1 so as to be movable up and down; the other tooth piece in the tooth pair 8 is fixedly connected to the support plate 4, the hydraulic connecting rod 7 is arranged obliquely, and the tooth pair 8 is arranged along the radial direction of the hydraulic cabin 1; the limit plate 9 is located between the hydraulic connecting rod 7 and a tooth piece of the tooth pair 8, and the limit plate 9 is fixedly connected to the outer wall of the hydraulic cabin 1; the outer wall of the hydraulic cabin 1 and the support plate 4 are also connected by a spring 5 which can be telescopic along the radial direction of the hydraulic cabin 1.

[0040] The piston 2 , the connecting rod 3 , the spring 5 , the hydraulic connecting rod 7 , the pair of latch teeth 8 and the limiting plate 9 are all installed on the same side of the hydraulic compartment 1 .

[0041] like Figure 3 As shown, the cover assembly includes a threaded column 10, a ring 11 and a nut 12; the threaded column 10 is installed at the opening position of the end of the cover assembly, and the side of the threaded column 10 close to the hydraulic cabin 1 is connected with the ring 11 through the nut 12, and the ring 11 is connected to the cable 18 of the vibration sensor 17; the hydraulic system includes a hydraulic pipe 15 and a hydraulic controller 16; one side of the threaded column 10 is connected to the hydraulic controller 16 through the hydraulic pipe 15; the hydraulic controller 16 adjusts the oil pressure in the hydraulic cabin 1 through the hydraulic pipe 15 and the threaded column 10.

[0042] The latching tooth pair 8 is composed of two latching tooth pieces, each of which is provided with a row of latching tooth structures, and the two latching tooth pieces are symmetrically arranged up and down, so that the latching tooth structures in the two latching tooth pieces can be connected by latching, that is, the two latching tooth pieces can be disengaged or locked together;

[0043] When the oil pressure in the hydraulic chamber 1 increases, the hydraulic connecting rod 7 extends outward, thereby driving one of the latching teeth 8 to move upward. The latching teeth moving upward are specifically the latching teeth fixedly connected to the hydraulic connecting rod 7, and the two latching teeth in the latching teeth 8 are disengaged. At the same time, the piston 2 extends outward as the oil pressure increases, driving the support sheet 4 to be pushed outward.

[0044] When the oil pressure in the hydraulic chamber 1 decreases, the hydraulic connecting rod 7 retracts inward, thereby driving one of the latching teeth 8 to move downward synchronously; at the same time, the piston 2 retracts inward as the oil pressure decreases, driving the support plate 4 and the other latching teeth to retract inward, and the two latching teeth contact and close and lock. The vibration sensor 17 and the support plate 4 are respectively located on both sides of the hydraulic chamber 1 in the radial direction.

[0045] In a specific implementation, the limiting piece 9 is used to limit the lateral pull-back deformation of the engaging tooth part, and can also limit the vertical movement of the first engaging tooth part.

[0046] A fin 13 is connected to the side of the hydraulic cabin 1 away from the telescopic assembly. The fin 13 is arranged along the axial direction of the hydraulic cabin 1, and the fin 13 and the telescopic assembly are arranged symmetrically on the left and right. A plurality of fixing holes 14 are opened on the fin 13, and the vibration sensor 17 is connected to the side wall of the hydraulic cabin 1 through the fin 13.

[0047] In a specific implementation, the fin 13 is installed on the non-supporting side end of the hydraulic cabin 1 , and the spring 5 is installed on the supporting side end of the hydraulic cabin 1 , and the spring 5 is fixedly connected to the supporting sheet 4 .

[0048] The installation device includes two telescopic components, through which the support plate 4 can be connected to the side wall of the hydraulic cabin 1 so as to move forward and backward radially along the hydraulic cabin 1. The two telescopic components are symmetrically arranged at both ends with the vertical middle of the hydraulic cabin 1 as the center.

[0049] The shell of the hydraulic cabin 1 and the support plate 4 are both made of metal materials. The compressive strength of the shell material of the hydraulic cabin 1 is not less than 200 MPa, and the bending strength of the material of the support plate 4 is not less than 200 MPa.

[0050] The shell of the hydraulic cabin 1 is made of a metal material with high compressive strength and is in the shape of a hexagonal prism; the support plate 4 is made of a metal material with high bending strength and is in the shape of an arc-shaped shell, and its length is 4 / 5 of the hydraulic cabin 1; the spring 5 is made of a fatigue-resistant metal material, and the fatigue strength of the spring 5 material is 200MPa. There are 2 springs, and the stiffness coefficient of the spring needs to be calculated and verified to ensure the stability of the vibration sensor; the piston 2 is sealed to the inner wall of the hydraulic cabin 1, and the sealing protection level is IP68; the hydraulic connecting rod 7 is sealed to the side wall of the connecting rod hole 6 in the hydraulic cabin 1, and the sealing protection level is IP68.

[0051] The buckle 11 has two sets of lock buckles, and the fixed position of the middle part of the buckle is adjustable. The outer length of the buckle 11 is adjusted not to exceed the outer boundary position of the vibration sensor 17 to avoid the buckle hindering the coupling of the vibration sensor 17 with the hole wall. The hydraulic chamber 1 has buckles 11 at both ends. When the number of vibration sensors 17 in the hole is greater than 1, the cable 18 of the deep vibration sensor 17 can be fixed on both sides of the installation device through the buckle 11 to avoid the vibration sensor 17 from squeezing and damaging the cable when coupling with the hole wall. The hydraulic controller 16 has the functions of regulating hydraulic pressure, stabilizing hydraulic pressure, and displaying hydraulic pressure values.

[0052] The method of the present invention comprises the following steps:

[0053] Step 1: First, manually press the support sheet 4 inwards. After the support sheet 4 compresses the spring 5 to a certain extent, the two latching teeth in the latching tooth pair 8 are closed and locked, so that the distance between the support sheet 4 and the outer wall of the hydraulic chamber 1 reaches the distance threshold;

[0054] In a specific implementation, the distance threshold is the minimum value of the distance between the support plate 4 and the outer side wall of the hydraulic compartment 1 during use.

[0055] Step 2: Connect the threaded column 10 at one end of the hydraulic cabin 1 to the hydraulic controller 16 through the hydraulic pipe 15, point the threaded column 10 at the other end of the hydraulic cabin 1 upward, start the hydraulic controller 16, and slowly inject hydraulic oil into the hydraulic cabin 1 through the hydraulic pipe 15 and the threaded column 10. When the hydraulic oil begins to overflow from the threaded column 10 at the lower end of the hydraulic cabin 1, close the hydraulic controller 16 and block the threaded column 10 at the lower end of the hydraulic cabin 1 to prevent the hydraulic oil from leaking out.

[0056] Step 3: Start the hydraulic controller 16, apply oil pressure to the hydraulic compartment 1 and stabilize the pressure for 10 minutes, and observe whether the oil pressure value displayed by the hydraulic controller 16 is stable:

[0057] If the oil pressure value is stable, it means that the installation device is well sealed, and you can go directly to step 4;

[0058] If the oil pressure value decreases, it indicates that there is leakage at the threaded column 10 at the end of the hydraulic chamber 1. Re-inject hydraulic oil and seal the threaded column 10 until the installation device is well sealed before proceeding to step 4.

[0059] Step 4: Manually press the support sheet 4 inward again, so that the distance between the support sheet 4 and the outer wall of the hydraulic cabin 1 reaches the distance threshold; place the vibration sensor 17 close to the fin 13 on the side wall of the hydraulic cabin 1, and use a wire to pass through the fixing hole 14 on the fin 13 to fix the vibration sensor 17 to the fin 13, that is, the vibration sensor 17 is fixed to the side wall of the hydraulic cabin 1 through the fin 13;

[0060] Since the support plate 4 is pushed outwards under the action of the oil pressure during the process of injecting the hydraulic oil in step 2, the state of the support plate 4 should be readjusted at the beginning of step 4 so that the support plate 4 and the hydraulic chamber 1 maintain a minimum distance.

[0061] Step 5: Connect the cable 18 of the vibration sensor 17 to the ring buckle 11, and adjust the position of the fixed end of the ring buckle 11 so that the outer edge of the ring buckle 11 does not exceed the outer edge of the vibration sensor 17;

[0062] Step 6: Figure 4 and Figure 5 As shown, the vibration sensor 17 and the mounting device are lowered along the borehole to the target position, the hydraulic controller 16 is turned on, and oil pressure is applied to the hydraulic chamber 1, and the hydraulic connecting rod 7 extends outward, thereby driving one of the latching teeth in the latching teeth pair 8 to move upward, so that the two latching teeth in the latching teeth pair 8 are disengaged; at the same time, the piston 2 extends outward as the oil pressure increases, and the spring 5 also pops outward, driving the support plate 4 to approach one side of the borehole wall 19; the telescopic assembly drives the vibration sensor 17 and the hydraulic chamber 1 to move to the other side of the borehole wall 19 until the support plate 4 and the vibration sensor 17 are both in close contact with the borehole wall 19, and at this time the vibration sensor 17 is fixed in the borehole;

[0063] Step 7: Next, the hydraulic controller 16 is turned off, and under the outward thrust of the spring 5, the vibration sensor 17 is tightly fixedly coupled to the borehole wall 19 for a long time;

[0064] Step 8. After a period of time, open the hydraulic controller 16, pump back the hydraulic oil in the hydraulic chamber 1, and the hydraulic connecting rod 7 retracts inward, thereby driving one of the gear pieces in the gear pair 8 to move downward; at the same time, the piston 2 retracts inward as the oil pressure decreases, driving the support plate 4 and the other gear piece to retract inward, and the two gear pieces contact and close and lock step by step, and the spring 5 is compressed; after the vibration sensor 17 falls off from the borehole wall 19, lift the vibration sensor 17 and the installation device out of the borehole, and recover the vibration sensor 17 and the installation device.

Step 4: Manually press the support plate (4) inward again so that the distance between the support plate (4) and the outer wall of the hydraulic chamber (1) reaches a distance threshold; place the vibration sensor (17) close to the fin (13) on the side wall of the hydraulic chamber (1), and use a wire tie to pass through the fixing hole (14) on the fin (13) to fix the vibration sensor (17) to the fin (13); Step 5: Connect the cable (18) of the vibration sensor (17) to the ring buckle (11), and adjust the position of the fixed end of the ring buckle (11) so that the outer edge of the ring buckle (11) does not exceed the outer edge of the vibration sensor (17); Step 6: Lower the vibration sensor (17) and the installation device along the borehole to the target position, turn on the hydraulic controller (16), apply oil pressure to the hydraulic chamber (1), and the hydraulic connecting rod (7) extends outward, thereby driving one of the latching teeth (8) to move, so that the two latching teeth in the latching teeth (8) are disengaged; at the same time, the piston (2) extends outward as the oil pressure increases, and the spring (5) also pops outward, driving the support plate (4) to move toward one side of the borehole wall (19); the telescopic assembly drives the vibration sensor (17) and the hydraulic chamber (1) to move toward the other side of the borehole wall (19) until the support plate (4) and the vibration sensor (17) are both in close contact with the borehole wall (19), and the vibration sensor (17) is fixed in the borehole; Step 7: Next, the hydraulic controller (16) is closed, and the vibration sensor (17) is fixedly coupled to the borehole wall (19) under the outward thrust of the spring (5); Step 8, open the hydraulic controller (16), pump back the hydraulic oil in the hydraulic chamber (1), and the hydraulic connecting rod (7) retracts inward, thereby driving one of the gear pieces in the gear pair (8) to move; at the same time, the piston (2) retracts inward as the oil pressure decreases, driving the support plate (4) and the other gear piece to retract inward, and the two gear pieces are closed and locked after contact, and the spring (5) is compressed; after the vibration sensor (17) and the borehole wall (19) fall off, lift the vibration sensor (17) and the installation device out of the borehole, and recover the vibration sensor (17) and the installation device.
