Description

Technical Field

[0001] This utility model relates to the field of coal mine rockburst detection technology, specifically to a micro-vibration sensor connector. Background Technology

[0002] In the existing technology, the microseismic monitoring system is a commonly used method for monitoring rockburst in mines. It forms a microseismic monitoring network by deploying multiple microseismic sensors underground to obtain rock fracture signals in and around the monitoring area. Typically, the microseismic sensors are directly fixed to the rock surface with anchor bolts.

[0003] Due to the unique structure of micro-vibration sensors, they can better receive vibration signals when the vibration direction is along the vertical direction of the sensor (i.e., the sensor's central axis). In underground mines, micro-vibration sensors are typically installed on anchor bolts. The installation process for anchor bolts involves manual drilling and installation of the bolts. The angle of the manually drilled holes determines the installation angle of the anchor bolts. Since the angle of the manually drilled holes often cannot guarantee vertical alignment, directly installing the micro-vibration sensor on the anchor bolts cannot ensure the sensor is installed vertically, resulting in the micro-vibration sensor not being able to guarantee vertical installation.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a micro-vibration sensor connector to solve the technical problem that micro-vibration sensors cannot guarantee vertical installation in related technologies.

[0010] Furthermore, the micro-vibration sensor connector includes: an inclination sensor connected to the micro-vibration sensor, the inclination sensor being used to measure the current inclination angle of the micro-vibration sensor; and an angle display meter connected to the inclination sensor signal, the angle display meter being used to display the current inclination angle of the micro-vibration sensor.

[0011] Furthermore, the micro-vibration sensor connector includes a mounting bracket, on which an inclination sensor and an angle display are mounted respectively, and the mounting bracket is connected to the universal joint seat body.

[0012] Furthermore, the mounting bracket includes a first support frame surrounding the universal joint seat body. The extension direction of the first support frame is parallel to the axis of the micro-vibration sensor. A locking hole is provided on the first side wall of the first support frame. A fourth internal thread is provided in the locking hole. A locking bolt is threaded into the locking hole. The end of the locking bolt passes through the locking hole and abuts against the outer surface of the universal joint seat body. The first support frame includes a second side wall disposed opposite to the first side wall. The second side wall is abutting against the universal joint seat body.

[0013] Furthermore, a positioning groove is provided on the outer surface of the universal joint seat body, the positioning groove being used to accommodate at least a portion of the locking bolt, and / or, the positioning groove being used to accommodate at least a portion of the second sidewall.

[0014] Furthermore, the first support frame includes a first opening, which is disposed between the first sidewall and the second sidewall.

[0015] Furthermore, the mounting bracket includes a second support frame connected to the first support frame. The second support frame includes: a first support plate, one end of which is connected to the first support frame, and the other end of which extends away from the first support frame, and an angle sensor is mounted on the first support plate; and a second support plate, which is connected to the first support frame, and extends perpendicularly to the first support plate, and an angle display is mounted on the second support plate.

This allows the micro-vibration sensor and the first universal joint arm to rotate around the second rotating shaft axis. The axes of the first and second rotating shafts are perpendicular to each other, making the two rotational degrees of freedom spatially independent and corresponding to angle adjustments in two orthogonal planes. This enables the micro-vibration sensor to flexibly adjust its orientation in three-dimensional space, allowing for vertical installation of the micro-vibration sensor as much as possible.

By adjusting the relative rotation angle of the micro-vibration sensor and the first universal joint arm, the sensor can rotate in any direction, allowing the attitude of the micro-vibration sensor to be flexibly adjusted. Operators can gradually correct the spatial attitude of the micro-vibration sensor, ultimately aligning its axis with the vertical direction, thereby ensuring that the micro-vibration sensor can be installed vertically, solving the technical problem in related technologies that micro-vibration sensors cannot guarantee vertical installation.

[0017] 3. The tilt sensor is connected to the micro-vibration sensor, which can sense the tilt angle of the micro-vibration sensor relative to the vertical direction. The angle display is connected to the tilt sensor signal, receiving and displaying the current tilt angle value of the micro-vibration sensor in real time. This allows operators to intuitively and continuously monitor the sensor's attitude changes at the installation site. During the angle adjustment process through the universal joint structure, the operator can control the rotation amplitude of the first and second universal joint arms based on the feedback data from the angle display, gradually adjusting the tilt angle to zero or the preset target value, thereby enabling the micro-vibration sensor to be installed vertically.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] According to an embodiment of this utility model, a micro-vibration sensor connector is provided. Please refer to [link / reference]. Figures 1 to 3 The device includes a universal joint, which comprises: a universal joint seat 1 connected to the micro-vibration sensor 10; a first universal joint arm 2 and a second universal joint arm 3. One end of the first universal joint arm 2 is connected to the universal joint seat 1 via a first rotating shaft 4, and the other end of the first universal joint arm 2 is connected to the second universal joint arm 3 via a second rotating shaft 5. The end of the second universal joint arm 3 away from the first universal joint arm 2 is connected to a fixing device for supporting the micro-vibration sensor 10. The axis of the first rotating shaft 4 is perpendicular to the axis of the second rotating shaft 5.

[0022] Specifically, the universal joint seat 1 is connected to the micro-vibration sensor 10, ensuring a reliable connection with the end of the micro-vibration sensor 10. The universal joint seat 1 is usually detachable or fixedly connected by means of threads, flanges or clips, which ensures connection strength while facilitating on-site installation and replacement.

[0023] Specifically, the first end of the first universal joint arm 2 is hinged to the universal joint seat 1 via the first rotating shaft 4, realizing the rotational degree of freedom of the micro-vibration sensor 10 around the axis of the first rotating shaft 4, thereby allowing for preliminary adjustment of the sensor's pitch angle. The second end of the first universal joint arm 2 is connected to the first end of the second universal joint arm 3 via the second rotating shaft 5, forming a second-stage hinge structure. This allows the micro-vibration sensor 10 and the first universal joint arm 2 to rotate around the axis of the second rotating shaft 5. The axes of the first rotating shaft 4 and the second rotating shaft 5 are perpendicular to each other, making the two rotational degrees of freedom spatially independent and corresponding to angle adjustments in two orthogonal planes. This allows the micro-vibration sensor 10 to flexibly adjust its orientation in three-dimensional space, enabling the micro-vibration sensor to be installed as vertically as possible.

[0024] Specifically, the second end of the second universal joint arm 3 is connected to a fixing device such as an anchor rod for supporting the micro-vibration sensor 10. This fixing device is usually pre-embedded or fixed in the roadway roof or rock mass.

[0025] In the micro-vibration sensor connector of this embodiment, by adjusting the relative rotation angle of the micro-vibration sensor 10 and the first universal joint arm 2, the sensor can rotate in any direction, so that the attitude of the micro-vibration sensor can be flexibly adjusted. The operator can gradually correct the spatial attitude of the micro-vibration sensor 10, and finally align its axis with the vertical direction, so that the micro-vibration sensor can be installed vertically as much as possible, thus solving the technical problem in the related art that the micro-vibration sensor cannot guarantee vertical installation.

[0026] In some embodiments, the universal joint seat 1, the first universal joint arm 2, and the second universal joint arm 3 are all cylindrical structures. At the hinge point between the first universal joint arm 2 and the universal joint seat 1 or at the hinge point between the first universal joint arm 2 and the second universal joint arm 3, the first universal joint arm 2 and the universal joint seat 1 are provided with mutually cooperating clearance grooves, and the first universal joint arm 2 and the second universal joint arm 3 are also provided with mutually cooperating clearance grooves.

[0027] In the micro-vibration sensor connector of this embodiment, see Figure 2-3 The universal joint seat 1 includes: a universal joint seat body 11, which extends along the axial direction of the micro-vibration sensor 10, and a first rotating shaft 4 is provided on the universal joint seat body 11; a connecting rod 12, which is connected to one end of the universal joint seat body 11 near the micro-vibration sensor 10, and the axial direction of the connecting rod 12 is consistent with the axial direction of the universal joint seat body 11, and a first external thread is provided on the outer circumferential surface of the connecting rod 12.

[0028] Specifically, the universal joint seat body 11 and the connecting rod 12 both extend along the axial direction of the micro-vibration sensor 10, and their structural directions are consistent with the central axis of the sensor body, ensuring the coaxiality of the attitude adjustment reference, providing a stable and centered support foundation for the first universal joint arm 2, and also enhancing the structural rigidity of the connection.

[0029] Specifically, by setting the connecting rod 12 and the first external thread, a threaded hole and a first internal thread are correspondingly set on the micro-vibration sensor, so that the universal joint seat 1 and the micro-vibration sensor are threadedly connected, thereby facilitating the installation and disassembly of the micro-vibration sensor.

[0030] In the micro-vibration sensor connector of this embodiment, see Figure 1 The second universal joint arm 3 has a connecting hole 31 at the end away from the first universal joint arm 2, and a second internal thread is formed in the connecting hole 31. With the above configuration, by setting the connecting hole 31 and the second internal thread, a threaded rod is set on the fixing device accordingly, so that the fixing device and the connecting hole 31 are threadedly connected, thereby facilitating the installation and disassembly of the micro-vibration sensor connector.

[0031] In some embodiments, a stop surface is provided at the end of the second universal joint arm 3 away from the first universal joint arm 2. The extension direction of the stop surface is parallel to the axial direction of the second universal joint arm 3. The stop surface facilitates clamping the second universal joint arm 3 when rotating it, thereby facilitating the installation and disassembly of the second universal joint arm 3.

[0032] In the micro-vibration sensor connector of this embodiment, see Figure 3 The micro-vibration sensor connector includes a locking nut 41. One end of the first rotating shaft 4 has a bolt head 42, and the outer circumferential surface of the other end of the first rotating shaft 4 has a third external thread. The first rotating shaft 4 is threadedly connected to the locking nut 41. Similarly, the micro-vibration sensor connector includes a locking nut 41. One end of the second rotating shaft 5 has a bolt head 42, and the outer circumferential surface of the other end of the second rotating shaft 5 has a third external thread. The second rotating shaft 5 is threadedly connected to the locking nut 41. After the micro-vibration sensor 10 is kept vertical, the bolt head 42 and the third external thread can be used to lock the universal joint, preventing unnecessary rotation of the first rotating shaft 4 and the second rotating shaft 5, thus keeping the micro-vibration sensor 10 in a relatively fixed position.

[0033] Optionally, the first rotating shaft 4 and the second rotating shaft 5 can directly use bolts from the existing technology.

[0034] In the micro-vibration sensor connector of this embodiment, see Figure 1The micro-vibration sensor connector includes: an inclination sensor 6, which is connected to the micro-vibration sensor 10 and measures the current inclination angle of the micro-vibration sensor 10; and an angle display table 7, which is signal-connected to the inclination sensor 6 and displays the current inclination angle of the micro-vibration sensor 10. Specifically, the inclination sensor 6, connected to the micro-vibration sensor 10, can sense the tilt angle of the micro-vibration sensor relative to the vertical direction. The angle display table 7, signal-connected to the inclination sensor 6, receives and displays the current inclination angle value of the micro-vibration sensor 10 in real time, allowing operators to intuitively and continuously monitor the sensor's attitude changes at the installation site. During angle adjustment via the universal joint structure, the operator can control the rotation amplitude of the first universal joint arm 2 and the second universal joint arm 3 based on the feedback data from the angle display table 7, gradually adjusting the inclination angle to zero or a preset target value, thereby further achieving vertical installation of the micro-vibration sensor 10.

[0035] In addition, during the use of the micro-vibration sensor, the rock strata in the tunnel will continue to deform, which will cause the installation direction of the anchor bolt to change. The micro-vibration sensor connector in this embodiment can also perform position verification of the micro-vibration sensor by the current tilt angle and adjust the angle according to the current tilt angle to ensure that the micro-vibration sensor 10 is always in a vertical installation state.

[0036] In some embodiments, the angle display 7 has a built-in battery and can be fixed by means of magnetism, bolts, etc.

[0037] In the micro-vibration sensor connector of this embodiment, see Figure 1 The micro-vibration sensor connector includes a mounting bracket 8, on which an inclination sensor 6 and an angle display 7 are mounted respectively. The mounting bracket 8 is connected to the universal joint seat body 11. By setting the mounting bracket 8 to support and fix the inclination sensor 6 and the angle display 7, the inclination sensor 6 can maintain the same position and attitude as the micro-vibration sensor 10, thereby enabling the current inclination angle of the micro-vibration sensor 10 to be obtained in real time.

[0038] In the micro-vibration sensor connector of this embodiment, see Figure 2 The mounting bracket 8 includes a first support frame 81 surrounding the universal joint seat body 11. The extension direction of the first support frame 81 is parallel to the axis of the micro-vibration sensor 10. A locking hole 812 is provided on the first side wall 811 of the first support frame 81. A fourth internal thread is provided in the locking hole 812. A locking bolt 83 is threaded into the locking hole 812. The end of the locking bolt 83 passes through the locking hole 812 and abuts against the outer surface of the universal joint seat body 11. The first support frame 81 includes a second side wall 813 disposed opposite to the first side wall 811. The second side wall 813 is abutting against the universal joint seat body 11.

[0039] Specifically, the first support frame 81 is arranged around the periphery of the universal joint seat body 11 and extends along the axial direction of the micro-vibration sensor 10, forming a ring-shaped structure around the universal joint seat body 11. The extension direction of the locking bolt 83 is perpendicular to the axial direction of the universal joint seat body 11. The locking bolt 83 is screwed into the fourth internal thread in the locking hole 812, and its end abuts against the outer surface of the universal joint seat body 11, thereby achieving radial locking of the first support frame 81. By tightening the locking bolt 83, the first side wall 811 can be moved away from the universal joint seat body 11, while the second side wall 813, as the opposite support surface, contacts the universal joint seat body 11, forming a two-point clamping structure, thereby firmly fixing the entire mounting bracket 8 to the universal joint seat body 11.

[0040] In the micro-vibration sensor connector of this embodiment, see Figure 2 A positioning groove 111 is provided on the outer surface of the universal joint seat body 11. The positioning groove 111 is used to accommodate at least part of the locking bolt 83 and the positioning groove 111 is used to accommodate at least part of the second side wall 813.

[0041] In some embodiments, the positioning groove 111 includes two positioning grooves that extend along the axial direction of the micro-vibration sensor and are arranged opposite to each other.

[0042] Specifically, the positioning groove 111 provides axial positioning and limiting functions for the locking bolt 83. The positioning groove 111 can accommodate at least part of the second sidewall 813, allowing the second sidewall 813 to be embedded in the groove during installation, thereby achieving circumferential alignment and axial positioning between the mounting bracket 8 and the universal joint seat body 11. This mating structure restricts the degrees of freedom of the first support frame 81 in the circumferential and axial directions of the universal joint seat body 11, preventing relative rotation or axial movement. The positioning groove 111, as a mechanical stop and mating surface, can improve the connection rigidity and stability between the mounting bracket 8 and the universal joint seat body 11.

[0043] In some embodiments, the axial position of the positioning groove 111 can be adjusted according to actual needs. For example, the end of the second sidewall 813 away from the micro-vibration sensor can abut against the sidewall of the positioning groove 111, and the end of the second sidewall 813 close to the micro-vibration sensor can abut against the end of the micro-vibration sensor. This can also achieve the axial positioning of the mounting bracket 8.

[0044] In the micro-vibration sensor connector of this embodiment, see Figure 2 The first support frame 81 includes a first opening 814, which is located between the first side wall 811 and the second side wall 813. By providing the first opening 814, it is convenient to fit the first support frame 81 onto the universal joint seat body 11, thus facilitating the installation and disassembly of the first support frame 81.

[0045] In the micro-vibration sensor connector of this embodiment, see Figure 2 The mounting bracket 8 includes a second support frame 82 connected to the first support frame 81. The second support frame 82 includes: a first support plate 821, one end of which is connected to the first support frame 81, and the other end of which extends away from the first support frame 81. An angle sensor 6 is mounted on the first support plate 821; and a second support plate 822, which is connected to the first support frame 81. The extension direction of the second support plate 822 is perpendicular to the first support plate 821. An angle display table 7 is mounted on the second support plate 822.

[0046] In some embodiments, the first support plate 821 is connected to the end of the second sidewall away from the micro-vibration sensor, the extension direction of the first support plate 821 is perpendicular to the axial direction of the micro-vibration sensor 10, and the extension direction of the second support plate 822 is parallel to the axial direction of the micro-vibration sensor 10.

[0047] By setting the first support plate 821 and the second support plate 822, the tilt sensor 6 and the angle display table 7 can be supported and fixed respectively. The extension direction of the second support plate 822 is perpendicular to the first support plate 821, which makes it convenient for the operator to directly observe the display data of the angle display table 7.
