Description

Technical Field

[0002] In the engineering field, drilling is commonly performed and sensors are installed in the boreholes for data collection, safety warnings, and other tasks. However, during long-term monitoring, damage caused by human intervention, animals, and the external environment is particularly prone to occur, which can affect the normal monitoring of the borehole and even cause it to be scrapped.

[0003] Therefore, the biggest challenge for ground drilling is hole mouth protection. If the borehole and hole mouth measuring line are not protected and exposed to the outside, they are easily affected by the sun and rain, thus affecting the normal use of the test system. At the same time, the exposed measuring line is easily damaged by other cross-construction, which is not conducive to theft prevention and reduces the service life of the drilling and test system. At present, hole mouth protection devices are generally covered with concrete bricks or iron barrels for protection, and are fixed. This simple covering prolongs the use of the borehole to a certain extent. However, this type of protection device is difficult to open, which limits the monitoring personnel from removing or inserting the monitoring instrument. In addition, this type of protection device does not have a monitoring and alarm system.

A wiring hole 7 is provided in the middle of the protective cover 2, and a measuring line 17 is passed through the wiring hole 7. The inner top surface of the protective cover 2 is an arc cone, which can prevent water accumulation or upside-down water from appearing on the inner top surface of the protective cover 2.

[0035] like Figure 6-Figure 9 As shown, the protective cover 2 and the inner wall of the upper end of the protective cylinder 1 are detachably connected through a locking device 4, and the locking device 4 includes a ring gear 41, five gears 42 evenly distributed on the inner wall of the protective cover 2, and five racks 43 respectively meshing with the five gears 42. The ring gear 41 extends outward and is provided with a card plate 44. The inner wall of the protective cover 2 is provided with a card groove 45 that cooperates with the card plate 44, and then the ring gear 41 is embedded in the inner wall of the protective cover 2, and the ring gear 41 can rotate relative to the protective cover 2. The gear 42 is connected to the inner wall of the protective cover 2 through a pad 46. The pad 46 is fixedly connected to the inner wall of the protective cover 2, and the gear 42 is rotatably connected to the pad 46. One of the five gears 42 is connected to a driving The motor 47 and the control switch of the driving motor 47 (not shown in the figure) are arranged on the top surface of the protective cover 2. The five gears 42 are all engaged with the ring gear 41 for transmission. The five racks 43 are respectively engaged with the five gears 42. The sides of the five racks 43 are provided with protrusions 48. The lower end of the side wall of the protective cover 2 is provided with five slide grooves 49 that cooperate with the protrusions 48. The five racks 43 are slidably connected to the lower end of the side wall of the protective cover 2 through the cooperation between the protrusions 48 and the slide grooves 49. The lower ends of the five racks 43 are fixedly connected with a first clamping block 410. The upper end ring of the inner wall of the protective tube 1 is provided with a groove 411. The first clamping block 410 cooperates with the groove 411 to fix the protective cover 2.

[0036] When the protective cover 2 needs to be fixed to the upper end of the protective tube 1, the control switch is used to control the driving motor 47 to drive the gear 42 provided on the control motor to rotate, and the five gears 42 are rotated synchronously through the ring gear 41, and the gear 42 drives the rack 43 to move toward the outside of the protective cover 2 in a straight line direction, and the rack 43 drives the first clamping block 410 provided thereon to move, and the first clamping block 410 is finally stuck in the groove 411 provided at the upper end of the inner wall of the protective tube 1, so that the protective cover 2 can be fixed on the protective tube 1; when the protective cover 2 needs to be removed, the control switch is used to control the driving motor 47 to rotate in the opposite direction, and the movement principle of the first clamping block 410 is the same as above, it moves toward the inside of the protective cover 2 in a straight line direction, and then escapes from the groove 411 provided on the protective tube 1, and the protective cover 2 can be removed.

[0037] The protective cover 2 is connected to the protective tube 1 through a locking device 4, and the locking and loosening are both driven by the drive motor 47 controlled by the control switch, making the installation and removal of the protective cover 2 more convenient; the control switch can be equipped with a fingerprint recognition system, which can reduce the possibility of the protective tube 1, the protective cover 2 and the instrument inside the protective tube 1 being stolen.

[0038] like Figure 1 、 Figure 10 As shown, a mounting seat 11 is provided at the lower end of the protective tube 1 for mounting and fixing on the drill hole; or a thread is provided at the bottom end of the protective tube 1 for mounting and fixing with the thread provided at the drill hole position.

[0039] like Figure 2-Figure 5 As shown, a track 8 is provided on the outer wall of the upper end of the protective tube 1, and a monitoring chamber 9 is detachably connected to the track 8. The monitoring chamber 9 includes a chamber body 91 and a second clamping block 92. The chamber body 91 and the second clamping block 92 are provided at the upper and lower ends of the track 8, and the second clamping block 92 is clamped to the chamber body 91 through a buckle portion 93.

[0040] The buckle portion 93 includes: a button 931 and a hook 932. A protrusion 933 is provided at one end of the button 931. A plurality of L-shaped holes 934 are provided on the side wall of the button 931. A blind hole 935 is provided at the lower end of the bin body 91. A spirally arranged slide 936 is provided on the side wall of the blind hole 935 near its closed end. The button 931 is placed in the blind hole 935, and the protrusion 933 provided thereon is placed in the slide 936. The button 931 is connected to the closed end of the blind hole 935 by a spring 937. A plurality of through holes 938 are provided on the side wall of the blind hole 935. The hook 932 is fixedly connected to the side wall of the second clamping block 92.

[0041] The bin body 91 and the second card block 92 are respectively placed at the upper and lower ends of the track 8, and the hook 932 is inserted into the bin body 91 through the through hole 938, and fixed with the button 931 through the L-shaped hole 934, so that the monitoring bin 9 can be fixed on the track 8; when the detection bin needs to be removed from the track 8, press the button 931 into the blind hole 935, and the protrusion 933 on the button 931 moves along the slide 936. Under the guidance of the slide 936, the button 931 rotates, so that the L-shaped hole 934 is rotated out of the position where the hook 932 is engaged, and the bin body 91 and the second card block 92 can be separated, and then removed from the track 8.

[0042] A driving unit 94 is provided in the warehouse body 91, and the driving unit 94 includes: a driving wheel 941 and a plurality of pulleys 942. The driving wheel 941 and the plurality of pulleys 942 are rotatably connected to the side wall of the warehouse body 91 on the side close to the track 8, and are in contact with the track 8. A first pulley 943 is fixedly connected to the driving wheel 941, and the first pulley 943 is connected to a second pulley 944 through a belt. The second pulley 944 is driven to rotate by a motor 945, and the motor 945 is fixed to the warehouse body 91. The motor 945 drives the driving wheel 941 to rotate through the belt, so that the driving wheel 941 can move along the track 8, driving the monitoring chamber 9 to move along the track 8. The multiple pulleys 942 are used to make the monitoring chamber 9 more stable during movement. The outer wall of the chamber body 91 is provided with a motor controller (not shown in the figure) for controlling the opening and closing of the motor 945, thereby controlling the hovering position of the monitoring chamber 9. The motor controller can also be equipped with a remote control module to enable the monitoring personnel to remotely control the position of the monitoring chamber 9.

[0043] A monitoring module 10 is installed in the warehouse body 91. The monitoring module 10 includes: an infrared detector 101 and a monitor 103. A cover 12 is provided on the warehouse body 91 to protect the monitoring module 10. The monitor 103 observes the surrounding environment of the protective tube 1 so that the monitoring personnel can promptly detect whether the protective tube 1 is at risk of being stolen. A data storage module (not shown in the figure) is also provided in the warehouse body 91 that is electrically connected to the infrared detector 101 and the monitor 103.

[0044] like Figure 11 、 Figure 12 As shown, the scale 3 is set at the position of an arc with a radius of 300 meters to 800 meters and the protective tube 1 as the center. Multiple scales 3 can be set at different positions of the arc. The surface of the scale 3 is a rough surface. Since infrared rays are more sensitive to rough surfaces than to smooth surfaces, the rough surface is convenient for reflecting the infrared light emitted by the infrared detector 101. The scale 3 cooperates with the infrared detector 101 provided in the monitoring chamber 9. The infrared detector 101 emits infrared rays and receives the infrared rays returned by the scale 3, thereby monitoring whether the azimuth angle of the protective tube 1 changes.

[0045] A heating plate can also be installed on the side of the scale 3 with scale markings and connected to an external power supply. Since infrared rays are more sensitive to heat, when it is necessary to detect the offset angle of the protective tube 1, it can indicate the direction for the infrared detector 101, making it convenient for the monitoring personnel to stop the monitoring chamber 9 to the position corresponding to the scale 3.

[0046] like Figure 10As shown, a battery 13 is provided on the inner wall of the protective tube 1. The battery 13 is placed on a bracket 14 provided on the inner wall of the protective tube 1. The battery 13 is used to collect the electric energy produced by the solar panel module 5 and send the electric energy to the sensor system 6, the measuring line 17, the drive motor 47, the motor 945, and the monitoring module 10. The drive system

[0047] Three support rods 15 are evenly distributed in the circumferential direction of the inner wall of the protective tube 1 and extend toward the center of the protective tube 1. The ends of the three support rods 15 away from the inner wall of the protective tube 1 are fixedly connected by a circular frame 16. The circular frame 16 is used to support the measuring line 17 passing through the drill hole. The measuring line 17 can be fixed to the circular frame 16 by means of a tether or the like. A flexible sensor 18 is also provided on the measuring line 17.

[0048] Flexible sensor 18 is a flexible nodal linear sensor, capable of sensing the spatial motion range of its corresponding position, namely, its movement pattern, displacement, and azimuth. The flexible nodal linear sensor consists of a flexible steel wire rope and a nodal sensor. The flexible steel wire rope is equipped with a nodal ring for suspending the nodal sensor; the nodal sensor is connected to the nodal ring via a fixed ring. During installation, the flexible nodal sensor is lowered by lowering the steel wire rope, and the nodal sensor is then installed at different nodal depths. The nodal sensor is then installed with the nodal sensor to the designated depth. Once installed in the designated location, the nodal sensor can dynamically sense the drilling pattern and spatial movement at its location.

[0049] The flexible node linear sensor realizes power supply and data transmission through its own connecting wires, and the data is transmitted to the data analysis terminal (not shown in the figure) set on the circular frame 16 of the ground protection barrel 1. Through the data analysis terminal data decoding, the morphology of different depths of the borehole can be obtained. The morphology result can be obtained through the borehole profile, and the left and front view position data can be obtained. Figure 13-15 As shown in FIG, the deformation trajectory inside the borehole can also be obtained by looking down at the left and front view data.

[0050] Data monitoring of the azimuth angle of protection tube 1:

[0051] Before the coal mining face begins, the ground does not sink. The infrared detector 101 stops and emits infrared rays when it rotates to the position where the monitoring chamber 9 corresponds to the scale 3. The scale 3 receives the infrared rays. At this time, the receiving range of the scale 3 is Acm. The data storage module records this data. The data collected at this time is background data. When the coal mining face begins to be mined, the ground sinks, the protective tube 1 tilts, and the infrared detector 101 also tilts. The monitoring chamber 9 is rotated again to the position corresponding to the scale 3 and stops. The infrared detector 101 reflects infrared rays. At this time, the infrared receiving range on the scale 3 also shifts, and the receiving range becomes Bcm. The data storage module can record and store this data. The monitoring personnel can perform this operation according to a certain period.

[0052] Monitoring personnel can collect data by connecting to the data storage module on site, or they can transmit the data wirelessly to the room through the remote transmission function of the data storage module. Through data decoding and visualization software, a three-dimensional subsidence model is presented, which is combined and corrected with the data from the flexible sensor 18 inside the borehole to present a visual state.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
