Description

Technical Field

[0001] The invention relates to the technical field of coal seam stress monitoring, and in particular to an angle detection device for detecting the installation angle of a borehole stress gauge. Background Art

[0002] As the depth of coal seam mining increases, the mine pressure will increase, and disasters such as rock burst will occur frequently. Therefore, the rock burst problem is essentially a stress problem of the coal body.

[0003] In order to monitor the changes in the relative stress of the coal body in real time, a borehole stress gauge is used for detection to ensure safe production in coal mines. At present, the borehole stress gauge is usually an oil pressure pillow type. In order to monitor the changing trend of the vertical stress of the coal body, the borehole stress gauge must be installed horizontally in the coal body borehole. At the same time, the diameter of the hole is usually small and the depth of the hole is deep. When placing the stress gauge, a wired angle detection device is usually used to blindly push the stress gauge to the preset position, and then the wired angle detection device is used to detect the angle of the stress machine.

[0004] However, when a wired angle detection device faces a relatively deep hole, a large amount of wires need to be put into the hole, so a worker is needed to assist in conveying the wires; and when the wired angle detection device is retrieved from the hole, a worker is also needed to assist in winding the wires, which increases labor costs and operation time, thereby reducing work efficiency. At the same time, since the channel in the hole is not smooth and there are stones, the wires may be worn, resulting in unstable signal transmission or wire breakage, increasing the cost of maintenance and replacement of the wires. In addition, in the case of a small hole diameter, the size of the wired angle detection device and the diameter of the wire may make it very difficult to recover, and sometimes the device may get stuck in the hole and cannot be removed, resulting in equipment loss and additional cleaning or repair work.

[0021] It can be seen that the angle detection device for detecting the installation angle of the borehole stress gauge provided by the present invention is simply provided with a push component 1, a control component 3 and a transceiver component 4, and the control component 3 and the transceiver component 4 are both arranged in the installation cavity 10 of the push component 1, and the control component 3 is electrically connected to the transceiver component 4, and the control component 3 is used to detect the installation angle of the borehole stress gauge, and transmit the detected installation angle of the borehole stress gauge to the transceiver component 4, and the transceiver part of the transceiver component 4 receives and transmits the installation angle of the borehole stress gauge detected by the control component 3 to the external receiver through wireless communication, and the staff can know the installation angle of the borehole stress gauge in the borehole through the external receiver, and then the staff can make real-time adjustments according to the detected current installation angle of the borehole stress gauge, so that the borehole stress gauge is installed horizontally in the coal body borehole. At the same time, the transceiver part of the transceiver component 4 and the external receiver adopt wireless communication, which can effectively eliminate the dependence on wired connection, thereby reducing the time and manpower requirements for wiring and wiring, and making the detection operation faster and more efficient. And the wireless design allows the detection device to move freely in the borehole without worrying about cable restrictions, so the operator can perform detection operations more flexibly, especially in complex or restricted drilling environments. And there is no need for additional personnel to handle the laying and recycling of cables, which reduces labor costs and reduces the cost of maintenance and replacement of wires. In addition, the transceiver part of the transceiver component 4 and the external receiver use wireless communication technology to enable the installation angle data of the drilling stress gauge to be transmitted to the external receiver in real time.

The angle detection device has a simple structure and is easy to operate. It can effectively solve the technical problem in the prior art that when using a wired angle detection device to detect the installation angle of the drilling stress gauge, additional manpower is required, thereby reducing the efficiency of the detection operation.

[0022] Furthermore, the wireless communication technology adopted by the transceiver part of the transceiver component 4 and the external receiver is ultra-wideband wireless carrier technology.

[0023] Optionally, the installation cavity 10 extends along the depth direction of the drill hole, the transceiver component 4 is located on one side of the control component 3 , and the transceiver component 4 and the control component 3 are sequentially arranged along the extension direction of the installation cavity 10 .

[0024] Optionally, in addition to receiving and sending information about the installation angle of the borehole stress gauge detected by the control component 3, the transceiver of the transceiver component 4 can also receive a calibration instruction sent by an external receiver through wireless communication, and send the calibration information to the control component 3, and the control component 3 performs a calibration procedure according to the sent calibration instruction. At the same time, the transceiver of the transceiver component 4 can also receive other instructions according to the working condition design, and send the instructions to the control component 3 or the external receiver.

[0025] Specifically, Figure 2 and Figure 5 As shown, the angle detection device also includes: an energy storage component 2, which is installed in the installation cavity 10, and the energy storage component 2 is located at a side of the control component 3 away from the transceiver component 4; the energy storage component 2 is used to store electric energy and supply power to the angle detection device; wherein the energy storage component 2 is electrically connected to the control component 3; the control component 3 is used to control the charging and discharging of the energy storage component 2. With such a structural setting, the angle detection device is no longer dependent on an external power supply by setting the energy storage component 2, which increases the portability of the device, so that it can work normally in field operations or confined spaces without power access, and improves the flexibility of the detection operation. In addition, the angle detection device can be powered without an external power supply, ensuring that the angle detection device can still work continuously in the event of a sudden power outage or unstable power supply, thereby improving the overall reliability of the system. At the same time, the control component 3 controls the charging and discharging of the energy storage component 2, which can realize intelligent energy management, such as charging when there is sufficient power supply, and using the stored electric energy when there is insufficient power supply or no power supply, which not only saves energy but also reduces the impact on the environment. By controlling the charging and discharging of the energy storage component 2, unnecessary power waste can be avoided, long-term operating costs can be reduced, and potential losses caused by power supply interruptions can be reduced, thereby improving cost-effectiveness.

[0026] Further, the energy storage component 2 is located at one side of the control component 3 .

[0027] Preferably, the energy storage component 2 is an energy storage battery.

[0028] Furthermore, in addition to detecting the installation angle of the drilling stress gauge and controlling the charging and discharging of the energy storage component 2, the control component 3 can also process the electricity input to the control component 3. This satisfies the specific power requirements of different electronic components in the angle detection device and ensures the quality and stability of the power supply.

[0029] Furthermore, the detection unit of the control component 3 is used to detect the installation angle of the drilling stress gauge.

[0030] Preferably, the detection unit of the control component 3 is an angle sensor.

[0031] Furthermore, the control component 3 is a control circuit board.

[0032] Specifically, Figures 1 to 4As shown, a first mounting port 11 connected to the mounting cavity 10 is provided on the side wall of the pushing component 1; the angle detection device also includes: a communication component 6, the communication component 6 is installed on the first mounting port 11, and at least part of the communication component 6 is located in the mounting cavity 10; the communication component 6 is connected to the control component 3, and the communication component 6 is used to receive instructions and exchange information with the control component 3. With such a structural arrangement, the communication component 6 is directly installed on the pushing component 1, which reduces additional connecting cables, makes the entire angle detection device more compact, improves the integration of the device, and is conducive to the miniaturization and portability of the device. In addition, the direct connection between the communication component 6 and the control component 3 simplifies the installation steps of the device and reduces the complexity of maintenance. When the communication component needs to be maintained or replaced, it can be directly carried out through the first mounting port 11 without disassembling the entire device, saving time and cost.

[0033] Specifically, Figures 1 to 4 As shown, the communication component 6 includes: a control switch unit 61, the control switch unit 61 is used to receive power-on instructions and charging instructions; a shutdown unit, the shutdown unit is used to receive shutdown instructions; a communication unit, the control switch unit 61 and the shutdown unit are both connected to the communication unit; and the communication unit is connected to the control component 3, and the communication unit is used to exchange information with the control component 3.

[0034] Furthermore, the communication part is connected to the control switch part 61, the shutdown part and the control component 3 respectively. The instructions received by the control switch part 61 and the shutdown part will be transmitted to the control component 3 through the communication part. At the same time, the control component 3 will feedback some information to the communication part, which will be sent to other corresponding components through the communication part.

[0035] Specifically, the angle detection device also includes: a display component, which is connected to the communication part of the communication component 6 and is arranged on the communication component 6. The display component is used to display the working status of the angle sensor at this time according to the feedback of the information of the control component 3.

[0036] Preferably, the display component is an indicator light.

[0037] Furthermore, when the control switch unit 61 receives a power-on instruction, the power-on instruction is transmitted to the control unit 3 through the communication unit. After receiving the power-on instruction, the control unit 3 controls the energy storage unit 2 to discharge, so that the energy storage unit 2 provides electrical energy for the angle detection device. At the same time, the control unit 3 will feed back the information of executing the power-on process and completing the power-on instruction to the communication unit of the communication unit 6, and the communication unit of the communication unit 6 will feed back to the display unit, so that the display unit located on the communication unit 6 will display accordingly. When the control switch unit 61 receives a charging instruction, the charging instruction will be transmitted to the control unit 3. After receiving the charging instruction, the control unit 3 will control the energy storage unit 2 to charge, and the external power supply will be transmitted to the control unit 3 through the control switch unit 61. The control unit 3 processes the electrical energy provided by the external power supply, and then transmits the processed electrical energy to the energy storage unit 2, so that the energy storage unit 2 is charged. When the shutdown unit receives the shutdown command, the shutdown command is transmitted to the control component 3 through the communication unit. After receiving the shutdown command, the control component 3 executes it and feeds back the result of the execution to the communication unit of the communication component 6. The communication unit of the communication component 6 feeds back to the display component, so that the display component located on the communication component 6 displays accordingly.

[0038] For example, when the control component 3 is in the process of executing the startup process, this information will be fed back to the communication part of the communication component 6, and the communication part will feed back this information to the indicator light, and the indicator light will perform corresponding actions, such as the light flashes at the first preset time or displays the first color. When the control component 3 completes the startup command, the angle detection device is in the on state at this time, and this information will be fed back to the communication part of the communication component 6, and the communication part will feed back this information to the indicator light, and the indicator light will perform corresponding actions, such as the indicator light changes from a flashing state to a constant light state, or changes to a second color. When the control switch part 61 receives the charging instruction, this information will be fed back to the communication part of the communication component 6, and the communication part will feed back this information to the indicator light, and the indicator light will perform corresponding actions, such as the light flashes at the second preset time or displays a third color. When the shutdown part receives the shutdown command, this information will be fed back to the communication part of the communication component 6, and the communication part will feed back this information to the indicator light, and the indicator light will go out. Specifically, the display of the indicator light is designed according to the actual situation.

[0039] Further, the communication component 6 is a communication circuit board, and the control switch part 61 is a magnetic switch. It can be understood that the magnetic switch is a part of the communication circuit board.

[0040] Preferably, the control switch portion 61 is a reed switch. When a magnet (such as a magnet) approaches the reed switch, the ferromagnetic reeds in the reed switch are magnetized and attract each other, thereby closing the contacts inside the reed switch. After the contacts are closed, a closed circuit is formed, which usually triggers the control component 3 to receive a signal. After the control component 3 recognizes this signal, it executes the power-on command and controls the energy storage battery to start discharging to power the angle detection device. And the control component 3 triggers a self-locking mechanism, even if the reed switch is subsequently disconnected, the angle detection device remains in an activated state.

[0042] Furthermore, at least a portion of the communication portion of the communication component 6 is electrically connected to the control component 3 through the connecting hole.

[0043] Furthermore, the outer surface of the mounting seat 5 is arranged flush with the side wall of the pushing component 1 .

[0044] Specifically, the mounting seat 5 includes a first side plate 51, a bottom plate 52, and a second side plate 53 connected in sequence, the first side plate 51 and the second side plate 53 are arranged opposite to each other, and the first side plate 51 and the second side plate 53 are both arranged to protrude from the bottom plate 52, the top surface of the bottom plate 52 is the mounting surface, and the first side plate 51, the bottom plate 52, and the second side plate 53 form a U-shaped groove. At the same time, at least part of the first side plate 51 and the second side plate 53 are located in the mounting cavity 10.

[0045] Further, at least a portion of the communication component 6 protrudes from the mounting groove 50 , and at least a portion of the communication component 6 protruding from the mounting groove 50 is located in the U-shaped groove.

[0046] Furthermore, the mounting groove 50 is a stepped groove, and the groove diameter of each groove of the stepped groove decreases successively along the groove depth of the stepped groove.

[0047] Preferably, the installation groove 50 is a two-step groove, and a connecting hole is provided on the groove close to the installation cavity 10, and the communication component 6 is installed in the groove.

[0048] Specifically, the angle detection device further includes a positioning member 8, which is adapted to a slot away from the mounting cavity 10, and is installed in the slot. The positioning member 8 is used to position the communication component 6 to prevent the communication component 6 from moving or vibrating in the mounting slot 50, thereby ensuring its stability and connection reliability.

[0049] Furthermore, a display hole is provided at the center of the positioning member 8, at least part of the communication component 6 and the display component correspond to the display hole, and the control switch part of the communication component 6 passes through the display hole, which allows the staff to observe the display component and the communication component 6.

[0050] Furthermore, the communication component 6 also includes five program burning interfaces, which are connected to the communication part. The five program burning interfaces correspond to the display holes. The five program burning interfaces are used to connect to external devices to facilitate program changes.

[0051] Specifically, Figure 1 As shown, the angle detection device further includes an observation window 9, which is sleeved on the mounting seat 5 to seal the mounting seat 5. The observation window 9 can protect the communication component 6 and other components to prevent dust from entering the mounting seat 5 and the mounting cavity 10.

[0052] Specifically, the control component 3 is a control circuit board; the transceiver component 4 includes: a transceiver circuit board 41 and a protective member 42, at least part of the transceiver circuit board 41 is arranged on the control circuit board, and the transceiver circuit board 41 forms the transceiver part of the transceiver component 4; a placement groove 420 is provided on the end surface of the protective member 42 close to the control circuit board, and at least part of the control circuit board and at least part of the transceiver circuit board 41 are inserted in the placement groove 420; wherein, the end surface of the protective member 42 close to the control circuit board abuts against the mounting seat 5. With such a structural setting, the transceiver circuit board 41 can be protected by setting the protective member 42, and the transceiver circuit board 41 can be effectively prevented from being physically damaged, such as impact, extrusion or vibration, thereby extending the service life of the circuit board. In addition, the direct contact between the transceiver circuit board 41 and the external environment can be isolated, dust, moisture, corrosive gases, etc. can be prevented from corroding the circuit board, the circuit board can be kept clean and dry, and the stable operation of the circuit board can be ensured.

[0053] Furthermore, the protective member 42 has a metal material or an electromagnetic shielding coating, which can reduce electromagnetic interference (EMI), protect the transceiver circuit board 41 from the influence of external electromagnetic fields, and maintain signal purity and communication quality.

[0054] Furthermore, at least part of the transceiver circuit board 41 is stacked on the control circuit board, and when at least part of the control circuit board and at least part of the transceiver circuit board 41 are inserted into the placement groove 420, the fixing member passes through the protective member 42 and abuts against the transceiver circuit board 41, so that the friction between the fixing member and the transceiver circuit board 41 is increased, thereby fixing the control circuit board and the transceiver circuit board 41. This enhances the stability of the circuit board and prevents the circuit board from moving or vibrating during installation.

[0055] Specifically, Figure 5 As shown, the protective member 42 is provided with a positioning groove, which extends along the circumferential direction of the protective member 42 to form an annular structure. The transceiver component 4 also includes a sealing member 43, which is sleeved on the protective member 42 and located in the positioning groove. The sealing member 43 abuts against the installation cavity 10, so that the sealing member 43 plays a role in sealing the installation cavity 10.

Such a structural setting is adopted to facilitate fixing the control circuit board, and the abutment between the main body 311 and the protective member 42 can also play a role of limiting.

[0057] Furthermore, the transceiver component 4 is located at a side of the control component 3 away from the energy storage component 2 , and when the transceiver component 4 is installed, the protective member 42 abuts against the mounting seat 5 (the protective member 42 abuts against the second side plate 53 ), thereby limiting the protective member 42 .

[0058] Specifically, Figure 2 and Figure 5 As shown, the angle detection device includes: a fixing component 7, the fixing component 7 is arranged in the installation cavity 10, and the fixing component 7 is located between the energy storage component 2 and the control component 3, and a clamping groove 70 adapted to the control component 3 is provided on the side of the fixing component 7 close to the control component 3, and the control component 3 is clamped and matched with the clamping groove 70. With such a structural setting, the control component 3 can be firmly fixed in the installation cavity 10 through the cooperation of the clamping groove 70 and the control component 3, and the loosening of the control component due to vibration or impact during the transportation or operation of the equipment can be avoided, thereby improving the reliability of the equipment. In addition, the design of the clamping groove 70 can accurately control the installation position of the control component 3, ensure that the electrical connection between it and other components (such as the transceiver component 4 and the energy storage component 2) is stable and reliable, and avoid poor contact or signal interference caused by position offset.

[0059] Furthermore, the fixing component 7 is also provided with an avoidance groove 72, which is connected to the clamping groove 70, and is located on one side of the fixing component 7 close to the control component 3. Specifically, the avoidance groove 72 and the clamping groove 70 are sequentially arranged on the fixing component 7 along the direction from the control component 3 to the energy storage component 2. By designing the avoidance groove 72, the electrical components on the control component 3 (control circuit board) can be avoided. In addition, this layout can make full use of the space in the installation cavity 10, avoid space waste, and contribute to the miniaturization and compact design of the device.

[0060] Specifically, Figure 6 As shown, the fixing component 7 has a receiving space 71, and the receiving space 71 is connected to the clamping groove 70; when the control component 3 is clamped and matched with the clamping groove 70, at least part of the control component 3 is located in the receiving space 71. With such a structural arrangement, the space in the installation cavity 10 can be fully utilized to avoid space waste, which is conducive to the miniaturization and compact design of the device.

[0061] Specifically, the fixing component 7 includes a first connecting plate, a second connecting plate and a third connecting plate connected in sequence, the first connecting plate and the third connecting plate are arranged opposite to each other, and the second connecting plate is located above the first connecting plate and the third connecting plate. The first connecting plate, the second connecting plate and the third connecting plate enclose an accommodating space 71. The first connecting plate and the third connecting plate are respectively provided with a clamping groove 70 and an avoidance groove 72.

[0062] Specifically, Figure 1 As shown, the pushing component 1 includes: a tube body 12 and a connector 13, the tube body 12 has an installation cavity 10, and the two ends of the tube body 12 are respectively provided with a second installation port 121 and a third installation port 122 connected to the installation cavity 10, the energy storage component 2 is close to the second installation port 121, and the transceiver component 4 is close to the third installation port 122; the connector 13 is connected to the tube body 12, and the connector 13 is used to block the second installation port 121; an inserting slot 130 is opened on the end of the connector 13 away from the tube body 12, when the pushing component 1 is connected to the drilling stress gauge, the drilling stress gauge is coaxially inserted into the inserting slot 130. With such a structural setting, the two ends of the tube body 12 are respectively provided with a second installation port 121 and a third installation port 122 connected to the installation cavity 10 for easy assembly, so that the components of the installation cavity 10 can be installed in the installation cavity 10 through the second installation port 121 and the third installation port 122.

[0063] Furthermore, the outer wall of the tube body 12 forms the outer wall of the pushing component 1 .

[0064] Furthermore, a fixed magnetic block is fixed at the bottom of the slot 130, and the fixed magnetic block fixes the borehole stress gauge by magnetic attraction, so that the borehole stress gauge can be inserted into the coal seam borehole together with the pushing component 1, and the pushing component 1 and the borehole stress gauge can be easily separated.

[0065] Specifically, the push component 1 has a tube body 12, and the tube body 12 is a rectangular tube body. With such a structural setting, the rectangular tube body has stronger anti-rotation performance than the circular tube body, and is not easy to rotate arbitrarily in the borehole, which is particularly important for the angle detection device, because the device needs to perform accurate measurements at a fixed angle, avoiding measurement errors caused by the self-rotation of the tube body. In addition, the rectangular tube body has a small cutoff frequency, small frequency requirements, and relatively small energy consumption requirements, so that the rectangular tube body can provide better signal transmission performance. At the same time, due to the low frequency requirements, the rectangular tube body also has relatively small energy consumption requirements, which helps to reduce the energy consumption of the entire angle detection device. And designing the tube body as a rectangular tube body can relax the requirements for frequency and energy consumption, so that when selecting other parts of the angle detection device, the designer can consider more types of components, without being limited to those high-frequency response or low-energy consumption high-end components, which directly reduces the manufacturing cost of the device. In addition, when the drilling depth exceeds the length of the push component 1, the length can be increased by splicing other rectangular tubes. The use of rectangular tubes can ensure uniform force at each joint, avoiding the rotation and displacement problems that may be encountered when circular tubes are spliced, and improving the stability and reliability of the entire push structure. The anti-rotation performance and splicing stability of the rectangular tubes make it more convenient for operators to deploy and retrieve the angle detection device in the borehole, reducing the number of adjustments or redeployments required due to component spin or instability, and improving work efficiency.

[0066] Specifically, the angle detection device is a cast-in and intrinsically safe angle detection device.

[0067] Furthermore, the communication component 6 adopts an intrinsically safe design.

[0068] Furthermore, the transceiver component 4 may also adopt an intrinsically safe design.

[0069] In this embodiment, the installation process of the angle detection device is as follows: First, the mounting seat 5 is mounted on the first mounting opening 11 and connected by welding.

[0070] Secondly, place the fixing component 7 into the installation cavity 10 from the second installation opening 121, push the fixing component 7 into the installation cavity 10 with the help of a tool, and make contact with the installation seat 5. Then place the energy storage component 2 into the installation cavity 10 from the second installation opening 121, and push the energy storage component 2 into the installation cavity 10 with the help of a tool. Note that the wire of the energy storage component 2 should be reserved longer at the beginning. When installing the energy storage component 2, first pass the wire of the energy storage component 2 through the accommodating space 71 of the fixing component 7, and then push the energy storage component 2 so that the wire of the energy storage component 2 passes through the third installation opening 122, so that the wire of the energy storage component 2 is located outside the tube body.

[0071] Again, place the assembled control circuit board (i.e., control component 3) and transceiver circuit board 41 in the placement groove 420 of the protective component 42 (the sealing component 43 has been installed on the protective component 42), then connect the wire of the energy storage component 2 to the control circuit board (i.e., control component 3), then enter the assembled control component 3 and transceiver component 4 into the installation cavity 10 from the third installation port 122, and push the control component 3 and transceiver component 4 toward the fixing component 7 with the help of a tool, so that the control circuit board (i.e., control component 3) is clamped in the clamping groove 70 of the fixing component 7, and the protective component 42 is abutted against the mounting seat 5.

[0072] When the control component 3 and the fixing component 7 are assembled, at least a portion of the control component 3 corresponds to the connecting hole of the mounting seat 5. The mounting seat 5 limits the position of the protective member 42 and the fixing component 7.

[0073] Again, the communication component 6 is first connected to the control component 3 through the connecting hole of the mounting seat 5, and then the communication component 6 is installed in the mounting groove 50, and then the observation window 9 is placed on the mounting seat 5. Finally, the liquid material for encapsulation is poured into the mounting cavity 10 through the second mounting port 121 to fix the components of the mounting cavity 10. At the same time, during encapsulation, the encapsulated liquid material will be blocked by the seal 43 so that at least part of the transceiver component 4 will not be encapsulated. The purpose of doing this is that the transceiver component 4 is a key component responsible for wireless communication in the angle detection device, and needs to exchange signals with the outside world. Therefore, its surface must be kept clean and open to prevent the encapsulation material from hindering signal transmission.

[0074] Finally, the connecting member 13 is inserted into the installation cavity 10 through the second installation opening 121 and fixed by bolts or screws.

[0075] Optionally, the angle detection device is used as follows: Step 1: First, coaxially insert the drilling stress gauge into the embedding slot 130 of the pushing component 1; then, turn on the angle detection device; finally, use the angle detection device or the angle detection device spliced ​​with a tube body used to increase the length of the angle detection device to push the drilling stress gauge to a preset position in the borehole.

[0076] Step 2: Use the detection part (i.e., angle sensor) of the control component 3 on the angle detection device to detect the installation angle of the drilling stress gauge in the borehole in real time; and the control component 3 transmits the detected installation angle of the drilling stress gauge to the transceiver part of the transceiver component 4. After receiving the installation angle of the drilling stress gauge, the transceiver part of the transceiver component 4 transmits the data of the installation angle of the drilling stress gauge in the borehole detected in real time by the detection part (i.e., angle sensor) of the control component 3 to an external receiver by wireless communication.

[0077] Step 3: After the external receiver receives the installation angle of the borehole stress gauge in the detection borehole from the angle detection device, the corresponding data will be displayed. After the operator sees the data of the installation angle of the borehole stress gauge in the current borehole, he will adjust the installation angle of the borehole stress gauge in the borehole through the angle detection device or the tube body used to increase the length of the angle detection device until the installation angle of the borehole stress gauge in the borehole displayed by the external receiver is horizontal.

[0078] The present invention provides an angle detection device for detecting the installation angle of a drilling stress gauge, the angle detection device comprising: a pushing component 1, a control component 3 and a transceiver component 4, the pushing component 1 is used to connect with the drilling stress gauge to send the drilling stress gauge to a preset position in a borehole, and an installation cavity 10 is provided in the pushing component 1; the control component 3 is installed in the installation cavity 10, and the control component 3 is used to detect the installation angle of the drilling stress gauge; the transceiver component 4 is installed in the installation cavity 10, the transceiver part of the transceiver component 4 is electrically connected to the control component 3, and the transceiver part of the transceiver component 4 is used to receive and send information on the installation angle of the drilling stress gauge detected by the control component 3; wherein the transceiver part of the transceiver component 4 is wirelessly connected to an external receiver, and the transceiver part of the transceiver component 4 sends the received information on the installation angle of the drilling stress gauge to the external receiver by wireless communication.

[0079] It can be seen that the angle detection device for detecting the installation angle of the borehole stress gauge provided by the present invention is simply provided with a push component 1, a control component 3 and a transceiver component 4, and the control component 3 and the transceiver component 4 are both arranged in the installation cavity 10 of the push component 1, and the control component 3 is electrically connected to the transceiver component 4, and the control component 3 is used to detect the installation angle of the borehole stress gauge, and transmit the detected installation angle of the borehole stress gauge to the transceiver component 4, and the transceiver part of the transceiver component 4 receives and transmits the installation angle of the borehole stress gauge detected by the control component 3 to the external receiver through wireless communication, and the staff can know the installation angle of the borehole stress gauge in the borehole through the external receiver, and then the staff can make real-time adjustments according to the detected current installation angle of the borehole stress gauge, so that the borehole stress gauge is installed horizontally in the coal body borehole. At the same time, the transceiver part of the transceiver component 4 and the external receiver adopt wireless communication, which can effectively eliminate the dependence on wired connection, thereby reducing the time and manpower requirements for wiring and wiring, and making the detection operation faster and more efficient. And the wireless design allows the detection device to move freely in the borehole without worrying about cable restrictions, so the operator can perform detection operations more flexibly, especially in complex or restricted drilling environments. And there is no need for additional personnel to handle the laying and recycling of cables, which reduces labor costs and reduces the cost of maintenance and replacement of wires. In addition, the transceiver part of the transceiver component 4 and the external receiver use wireless communication technology to enable the installation angle data of the drilling stress gauge to be transmitted to the external receiver in real time. The staff can obtain the test results immediately and make decisions quickly, avoiding the problems that may be caused by data delays. The angle detection device has a simple structure and is easy to operate. It can effectively solve the technical problem in the prior art that when using a wired angle detection device to detect the installation angle of the drilling stress gauge, additional manpower is required, thereby reducing the efficiency of the detection operation.
