Description

Technical Field

[0001] The invention belongs to the technical field of deep surrounding rock detection, and in particular relates to an automatic monitoring device for surrounding rock relaxation depth. Background Art

[0002] In the process of underground engineering excavation, in order to analyze the stability of the surrounding rock, it is often necessary to determine the changes in the relaxation depth of the surrounding rock during the rock mass excavation process to provide a data basis for the stability analysis. Under actual engineering conditions, the relaxation depth of the surrounding rock is affected by multiple factors such as the properties of the surrounding rock, ground stress, and excavation methods. The mechanism and process of its formation and development are very complex, and it is difficult to make accurate judgments with existing theoretical calculations and numerical simulations. Therefore, in engineering practice, it is often necessary to use a variety of on-site monitoring methods to realize the monitoring of the relaxation depth of the surrounding rock. Among them, borehole video technology and acoustic wave testing are two of the more commonly used monitoring methods for monitoring the relaxation depth of the surrounding rock. At the same time, because the two have certain similarities in the monitoring process, for example, the two usually use the same borehole in the monitoring process, and the monitoring equipment has a certain degree of repeatability. After research, it was found that the current monitoring equipment for borehole imaging technology and acoustic wave detection methods is relatively large, and some of the equipment is repeated. For example, the equipment for acoustic wave detection technology mainly includes acoustic wave probes, cables, probes, and acoustic wave collectors; the equipment for borehole video technology mainly includes camera probes, cables, probes, tripods, depth lines, and borehole video collectors. In the process of using borehole imaging technology and acoustic wave detection methods to monitor rock masses, the movement of the probe and cable in the borehole is mainly to manually push and pull the probe after connecting the probe rod.

[0003] That is, in terms of the technology for detecting the relaxation depth inside the surrounding rock through drilling, the problem is solved by combining acoustic detection and video detection, but there are technical disadvantages of complex equipment, equipment overlap, high repetition, and low automation of the detection process.

[0070] The technical scheme of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0071] At the same time, in the embodiments of this specification, when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in the embodiments of this specification are for illustrative purposes only and are not intended to limit the present invention.

[0072] Before explaining the present application through the first embodiment, it should be noted that in the process of studying the relaxation depth of surrounding rock, acoustic wave testing and borehole video technology are two research methods that are widely used and have relatively accurate test results. The acoustic wave testing method is based on the different propagation characteristics of sound waves in different media. When the density of the rock mass changes or joints and cracks appear, the speed and amplitude of the sound wave will respond, and then the development of the rock damage zone is judged by the change in the wave velocity of the sound wave. The acoustic wave testing method is widely used because of its fast and convenient characteristics. Using the acoustic wave testing technology, the relaxation depth of the surrounding rock and its changes under the time effect conditions can be accurately obtained. Borehole video technology uses the principle of optical imaging to display the detailed features inside the borehole, and interprets the distribution of cracks or discontinuities observed through technical interpretation to summarize and evaluate the development law of the relaxation depth of the surrounding rock. It has the characteristics of clarity and intuition, and is of great significance for understanding the development and changes of cracks or discontinuities inside the surrounding rock.

[0073] At present, the joint monitoring of the relaxation depth of surrounding rock through the acoustic test method and borehole camera technology has been widely used in actual projects. However, through field measurements, it is found that there are still areas for improvement in the current monitoring equipment. Through the on-site use of the monitoring equipment, it is found that the current monitoring equipment mainly has the following problems that can be improved:

[0074] 1) The current monitoring equipment for borehole imaging technology and acoustic wave detection methods is relatively large, and some of the equipment is repeated. For example, the equipment for acoustic wave detection technology mainly includes acoustic wave probes, cables, probes, and acoustic wave collectors; the equipment for borehole video technology mainly includes video probes, cables, probes, tripods, depth lines, and borehole video collectors. Therefore, in view of the reality that there are multiple duplicates in the monitoring equipment of both, how to streamline and improve the monitoring equipment while ensuring the monitoring results is a key issue that needs to be solved urgently.

[0075] 2) The borehole imaging technology and the acoustic wave detection method have a low degree of automation in the monitoring process. In the process of using the borehole imaging technology and the acoustic wave detection method to monitor the rock mass, the movement of the probe and the cable in the borehole is mainly to connect the probe rod and then push and pull the probe manually. This monitoring method not only consumes manpower and has a large workload, but also the monitoring results are usually unsatisfactory. For example, in the process of borehole photography, in order to ensure the clarity of the result image, the movement of the probe in the borehole is required to be slow and uniform; in the acoustic wave test process, the distance of each probe movement is also required to be kept at 20cm, otherwise the drilling depth may not be obtained accurately enough. These problems are greatly affected by the subjective factors of the operator during manual operation and are difficult to be accurately controlled. Therefore, in order to obtain more accurate monitoring results, how to improve the degree of automation of monitoring equipment is the key to solving this problem.

[0076] 3) In the actual monitoring process, dust is usually deposited in the borehole wall at the construction site, resulting in dust accumulation in the monitored borehole, which affects the monitoring results. Therefore, how to prevent dust from entering the borehole during construction is a key issue in whether the relaxation depth of the surrounding rock can be normally monitored. At the same time, in the process of continuous monitoring of the relaxation depth of the surrounding rock, in order to obtain the evolution process of the relaxation depth of the surrounding rock and conduct continuous research on rock damage, it is usually necessary to conduct multiple continuous monitoring of a borehole. This monitoring method is often time-consuming and labor-intensive. Therefore, how to achieve cyclic monitoring of a borehole at certain time intervals is a key issue in conducting research on the evolution of surrounding rock damage. The following will specifically solve the technical problems summarized in the above background through the implementation method of this embodiment one:

[0077] Embodiment 1:

[0078] like Figure 1-9 As shown, the first embodiment provides an automatic monitoring device for surrounding rock relaxation depth, which is used for deep detection in a borehole. The device includes an acoustic wave acquisition probe and a camera probe 19. The system includes: an acoustic wave acquisition probe and a camera probe 19 integrated into an integrated structure, a pair of mobile devices, a borehole plugging device and a control component;

[0079] The sound wave acquisition probe includes a sound wave transmitting probe 16 and at least one pair of sound wave receiving probes, and a camera probe 19, the sound wave transmitting probe 16 and at least one pair of sound wave receiving probes are arranged at intervals; a pair of mobile devices are correspondingly arranged at both ends of the integrated structure, and are used to drive the integrated structure to move in the borehole; the orifice sealing device is arranged at one end of the integrated structure away from the deep part of the borehole, and is used to temporarily seal the orifice of the borehole after the integrated structure enters the borehole; the control component is electrically connected to the sound wave acquisition probe and the camera probe 19, and is communicatively connected to an external mobile terminal device.

[0080] Specifically, the present invention proposes an automatic monitoring device for the relaxation depth of surrounding rock, which integrates an acoustic wave acquisition probe and a camera probe 19 into an integrated structure, thereby avoiding the technical disadvantages of complex equipment, equipment overlap and high repetition caused by using the two as separate detection components for detection or testing in the prior art. At the same time, a pair of mobile devices arranged at the ends of the integrated structure are used to make the acoustic wave acquisition probe and the camera probe 19 in the integrated structure convenient to move when performing detection or testing. Finally, the orifice of the borehole is temporarily blocked by a hole blocking device to prevent dust from entering the borehole; specifically, by integrating the camera probe 19, the acoustic wave transmitting probe 16 and at least one pair of acoustic wave receiving probes into a whole, the technical problems of equipment overlap and high repetition caused by using separate acoustic wave acquisition devices and camera devices to work in the prior art are solved, as well as the problems of low automation and dust accumulation in the borehole caused by manually pulling the acoustic wave acquisition device and the camera device in and out of the borehole in the prior art are solved.

[0081] It should be noted that a built-in power supply is also provided in the integrated structure, and the above-mentioned electrical devices are powered by the built-in power supply. The integrated structure is connected to the mobile device through an external thread connector 21 and an internal thread connector 12; wherein a pair of sound wave receiving probes includes a first sound wave receiving probe 18 and a second sound wave receiving probe 20, which are arranged at an interval;

[0082] In some possible implementations, a pair of mobile devices each include: a first housing; a drive motor 9 disposed in the first housing and arranged along the axial direction of the first housing, a first bevel gear 1 being disposed at a drive end of the drive motor 9; four second bevel gears being disposed in a radial direction of the first housing, each bevel gear being meshed with the first bevel gear 1, and each second bevel gear being connected to a wheel 15 via a transmission assembly; wherein, when the drive motor 9 drives the first bevel gear 1 to rotate clockwise or counterclockwise, the four second bevel gears are driven to rotate synchronously to transmit the rotational force to the wheel 15 via the corresponding transmission assembly to drive the wheel 15 to rotate, so that the integrated structure is displaced in the borehole;

[0083] This is because, when detecting a borehole, the probe is required to move slowly and evenly in the borehole, so the driving motor 9 drives the four second bevel gears meshing with the first bevel gear 1 evenly through the first bevel gear 1, and then the second bevel gear drives the wheel 15 to move slowly and evenly in the borehole. This solves the problem of inaccurate detection or testing caused by the inability to accurately control the displacement frequency of the probe during manual operation in the prior art.

[0084] Further, in some possible embodiments, the transmission assembly includes a transmission rod, one end of which is connected to a telescopic threaded rod 36 2 with an external thread, the telescopic threaded rod 36 2 is adaptably connected to a telescopic tube 5 with an internal thread, and a telescopic controller 3 is arranged between the telescopic threaded rod 36 2 and the telescopic tube 5; a first pressure sensor 4 is arranged in the telescopic tube 5, and the first pressure sensor 4 is connected to the control assembly; a tail end gear 7 is arranged at the other end of the transmission rod; the wheel 15 is arranged on the transmission rod through a wheel fixer 6, and a disc gear 8 is arranged on the wheel 15, and the disc gear 8 is meshed with the tail end gear 7.

[0085] In this way, when the driving motor 9 drives the first bevel gear 1 to rotate clockwise or counterclockwise, the telescopic thread 36 rod 2 is driven to move relative to the telescopic tube 5. When the control component detects that the pressure value is greater than the preset pressure threshold through the first pressure sensor 4, the telescopic controller 3 is controlled to lock the telescopic thread 36 rod 2 and the telescopic tube 5, so that the transmission rod rotates to drive the meshing disc gear 8 to rotate.

[0086] In some possible implementations, the device further includes: a pair of second pressure sensors 14, the pair of second pressure sensors 14 being correspondingly disposed at the ends of both ends of a pair of mobile devices;

[0087] This is to achieve the technical purpose of "automatic" displacement of the integrated structure in the borehole. Specifically, a pair of second pressure sensors 14 arranged at the ends of the mobile device will detect the pressure in real time, that is, when the walking device walks to the end of the hole, it will generate a pressure signal exceeding the preset pressure threshold, thereby determining the position of the integrated structure;

[0088] Further, in some possible implementations, the control component includes a Bluetooth 23 component and a controller, and the Bluetooth 23 component is communicatively connected with the acoustic wave transmitting probe 16, at least one pair of acoustic wave receiving probes, a pair of second pressure sensors 14, a driving motor 9, and an external mobile terminal device;

[0089] When the Bluetooth 23 component is used to receive electronic signals from at least a pair of sound wave receiving probes of the sound wave transmitting probe 16 and a pair of second pressure sensors 14, and send the electronic signals to the controller, the controller then sends control instructions according to the preset control logic. For example, when the controller receives a pressure signal exceeding the preset pressure threshold sent by the second pressure sensor 14, it will determine that one end of the integrated structure has reached the inner end of the borehole, and will control the drive motor 9 to rotate away from the depth direction of the borehole, thereby causing the mobile device to drive the integrated structure to move outside the hole.

[0090] In some possible implementations, the device further includes: a distance measuring device 10; the distance measuring device 10 is communicatively connected to the Bluetooth 23 component; and further includes a distance measurement control center 11 for receiving and processing distance signals;

[0091] In this way, the displacement of the integrated structure can be measured by the distance measuring device 10, for example, stopping for a fixed time every 20 cm and then moving again to reserve sufficient time for detecting and inspecting the inside of the borehole.

[0092] In some possible embodiments, the plugging assembly includes: a water injection pipe 24, a first mounting portion and a second mounting portion are sleeved outside one end of the water injection pipe 24 extending into the orifice, a pair of first support rods 38 are oppositely arranged on the first mounting portion, one end of the first support rod 38 is hingedly arranged on the first mounting portion, a pair of second connecting rods are oppositely arranged in the length direction of the first support rod 38, one end of the pair of second connecting rods is correspondingly arranged on the rod body of the pair of first support rods 38, and the other end of the second connecting rod is hingedly arranged on the water injection pipe 24;

[0093] In this way, when the water injection pipe 24 extends outward toward the borehole, it pushes the first support rod 38 to move toward the second connecting rod, so that the other end of the second connecting rod pushes the other end of the first support rod 38 toward the wall of the borehole. A telescopic knob 25 is provided at the end of the water injection pipe 24 away from the depth of the borehole, and the water injection pipe 24 is threadedly connected; the water injection port 34 of the water injection pipe 24 is used to inject clean water;

[0094] In some possible embodiments, the orifice plugging device also includes a probe recovery power assembly, which includes: a second shell body sleeved on the outside of the water injection pipe 24, the volume of the second shell body is larger than the volume of the orifice of the borehole, and is located at the orifice; a motor 27 is arranged in the second shell body, and a third bevel gear 33 is arranged at the driving end of the motor 27; a winding drum 28, the winding drum 28 includes a winding portion, and the winding portion is connected through a winding shaft with a fourth bevel gear at one end, and the fourth bevel gear is meshed with the third bevel gear 33, and a cable 42 is arranged on the winding portion, one end of the cable 42 is connected to a power supply, and the other end of the cable 42 is connected to the drive motor 9 and supplies power, and is connected to the integrated structure through the cable 42 to provide energy for the acoustic wave acquisition probe and the camera probe 19 of the integrated structure and to transmit data. The probe power recovery assembly also includes a motor movement control center 29, a data storage center 30, a device control center and a second power supply 32; the side wall of the second shell is also provided with a connecting hole, a telescopic thread 36 is provided in the connecting hole, and the second shell is temporarily fixed to the outer wall of the drill hole through an auxiliary fixing bolt 35 and the telescopic thread 36; a charging hole 41 and a data transmission hole 40 are also provided on the second shell to facilitate charging and data transmission.

[0095] Further, in some possible implementations, a pair of guide rails 26 are provided in the horizontal direction of the motor 27, and the pair of guide rails 26 clamp the motor 27 therein; a mobile control center, and the mobile control center is used to control the displacement of the motor 27 on the guide rails 26;

[0096] Specifically, the cable 42 is wound around the reel portion, and the reel portion is connected to the motor 27 through the third bevel gear 33 and the fourth bevel gear. The motor 27 moves on the guide rail 26 under the control of the mobile control center to achieve the engagement and disconnection of the third bevel gear 33 and the fourth bevel gear, thereby providing power for the recovery of the integrated structure.

[0097] In some possible implementations, a water level sensor 39 and a water injection control valve 37 are also provided on the water injection pipe 24; the water level sensor 39 is provided at a deep position of the water injection pipe 24 close to the borehole; the water injection control valve 37 is provided at a position of the water injection pipe 24 close to the orifice of the borehole;

[0098] This is because when water is injected through the water injection pipe 24, the water level is detected by the water level sensor 39, and when the water level reaches the target water level, the water injection pipe 24 is controlled by the water injection control valve to stop injecting water.

[0099] In another embodiment, the integrated structure, the pair of mobile devices and the orifice plugging device are each provided with a power supply device for supplying power to the respective power-consuming devices, and the power supply device includes: a first power supply 13, a second power supply 32 and a third power supply 22;
