Description

Technical Field

[0001] This invention relates to the field of sensor installation and positioning under deep hole testing conditions, and specifically to a positioning and installation device for sensors buried in deep holes. Background Technology

[0002] In existing deep-hole explosion tests, because the explosion point is located at a depth of tens of meters, the explosion wave spreads in all directions and attenuates rapidly in the soil and rock layers. If the sensor is installed by excavation and backfilling, the manpower and material resources required are enormous. If the test sensor is only deployed on the ground, the test effect will be greatly reduced. The most economical and convenient way is to drill holes at suitable locations around the explosion point. The drilling depth and location are determined by the location of the deep-hole explosion. Then, the test sensor is precisely installed and buried in the deep hole. Therefore, how to bury the test sensor in the deep hole is an urgent problem to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a positioning and installation device for sensors buried in deep holes. Its overall structure is scientifically designed, simple in composition, and easy to install and operate. This sensor positioning and installation device solves the problem of convenient and rapid deployment of sensors in deep holes, and effectively improves the convenience of sensor deployment and installation and the effectiveness of data acquisition in deep hole explosion tests.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A positioning and installation device for deep hole buried sensors includes: a base, an in-hole support, and a turntable assembly. The base consists of a chassis body, a steel wire rope, and connecting screws. The steel wire rope is fixedly connected to the chassis body, and the connecting screws are located on the chassis body. An in-hole support is installed on the base, and the chassis in the base is connected to both ends of the in-hole support via the connecting screws. A turntable assembly adapted for sensor installation is installed on the in-hole support, and the bottom of the turntable assembly is securely connected to the in-hole support. The in-hole support is welded from a single metal plate and two upper and lower fixed chassis, wherein the two fixed chassis are respectively welded to both ends of the metal plate.

[0006] Furthermore, the wire rope is joined to the chassis body by welding or pressing, and the length of the wire rope is determined by the depth of the deep hole during actual use.

[0007] Furthermore, a suitable number of weight-reducing holes are distributed in the middle of the support inside the hole.

[0008] Furthermore, the turntable assembly includes a mounting bracket, a rotating platform, fastening bolts, and a hinge. The upper surface of the rotating platform is used for sensor mounting. The bottom of the mounting bracket is mounted on an internal support and connected to the internal support via fastening bolts. A hinge is provided on the mounting bracket, and the rotating platform is mounted on the mounting bracket and hinged to the mounting bracket via the hinge.

[0009] Furthermore, there are scale markings on the curved surfaces of the mounting base and the turntable, which are used to determine the fixed rotation angle of the turntable.

[0010] Furthermore, in the positioning and installation device for deep hole buried sensors, the base, the in-hole support, and the turntable assembly constitute a single component module. The assembly method of the single component module is that the base and the in-hole support are fastened with bolts and nuts, the turntable assembly is installed on the in-hole support, the wire rope and the in-hole support are notched and embedded, and the modules are connected to each other by connecting bolts on the previous module.

[0011] Furthermore, the individual component modules can be spliced ​​and combined according to the depth of the deep hole, and the length and maximum outer diameter of the individual component module are determined according to the hole depth, hole diameter and actual construction conditions.

[0012] Furthermore, the mounting bracket is fixed to the bracket inside the hole with screws, and the sensor is pasted on the upper surface of the rotating disk. The rotation angle of the rotating table relative to the mounting base is calculated based on the relationship between the installation position of each sensor and the position of the explosion point. The corresponding rotation angle is then fixed by tightening the lock nut to ensure that the sensitive surface of the sensor is perpendicular to the explosion point after installation.

[0013] The beneficial effects of this invention are as follows: The overall structure of the positioning and installation device for deep hole buried sensors provided by this invention is scientifically and ingeniously designed. This invention solves the problem of positioning and installing deep hole explosion sensors. The modular design allows operators to assemble the sensors in series according to different working conditions. The base and the hole support are connected by studs and nuts, and the hole support is connected by screws and nuts, which can effectively position the sensors and facilitate rapid assembly. The lightweight design of the hole support facilitates construction operations. At the same time, the rotation angle of the turntable assembly allows for convenient and quick precise installation of the sensors. For the same working condition, all components can be uniformly processed and installed before deep hole burial, making the deep hole explosion testing process more economical, convenient, and efficient. This invention solves the problem of convenient and rapid sensor deployment in deep holes and is suitable for widespread promotion and application. Attached Figure Description

[0027] As per the instruction manual Figure 1 As shown, the present invention provides a positioning and installation device for sensors buried in deep holes, comprising: a base 1, an in-hole support 2, and a turntable assembly 3. The base 1 consists of a chassis body 11, a steel wire rope 12, and connecting screws 13. The steel wire rope 12 is fixedly connected to the chassis body 11, and the connecting screws 13 are mounted on the chassis body 11. The in-hole support 2 is mounted on the base 1, and the chassis in the base 1 is connected to both ends of the in-hole support 2 via the connecting screws 13. A sensor mounting adapter is installed on the in-hole support 2. The turntable assembly 3 is fixedly connected to the bottom of the hole support 2. The hole support 2 is welded together from a single metal plate 21 and two upper and lower fixed base plates 22. The two fixed base plates 22 are respectively fixedly welded to the two ends of the metal plate 21. The steel wire rope 12 is combined with the base plate 11 by welding or pressing. The length of the steel wire rope 12 is determined by the depth of the deep hole in actual use. In order to reduce the overall weight of the hole support 2, a suitable number of weight-reducing holes are distributed in the middle of the hole support 2.

[0028] As per the instruction manual Figure 3As shown, the turntable assembly 3 for mounting and supporting the sensor includes a mounting bracket 31, a rotating platform 32, fastening bolts 33, and a hinge 34. The upper surface of the rotating platform 32 is used for sensor mounting. The bottom of the mounting bracket 31 is mounted on the inner hole support 2 and connected to the inner hole support 2 by the fastening bolts 33. The hinge 34 is provided on the mounting bracket 31, and the rotating platform 32 is mounted on the mounting bracket 31 and hinged to the mounting bracket 31 by the hinge 34. Scale markings 35 are provided on the curved surfaces of the mounting base 1 and the rotating platform 32. During use, the scale markings 35 are used to determine the rotation angle of the turntable.

[0029] As per the instruction manual Figure 8 As shown in the attached instruction manual Figure 9 As shown, the positioning and installation device for sensors buried in deep holes is assembled in the following manner: the base 1 and the in-hole support 2 are fastened together with bolts and nuts; the turntable assembly 3 is installed on the in-hole support 2; the wire rope 12 is notched and embedded in the in-hole support 2; and the modules are connected and continued to each other by connecting bolts on the previous module. In use, multiple modules can be spliced ​​and combined according to the depth of the deep hole 4. The length and maximum outer diameter of a single positioning and installation device (single component module) are determined according to the hole depth, hole diameter, and actual construction conditions. During installation, the mounting bracket 31 is fixed to the in-hole support 2 with screws, and the sensor is pasted on the upper surface of the rotating disk. The rotation angle of the rotating table 32 relative to the mounting base 1 is calculated based on the relationship between the installation position of each sensor and the position of the explosion point, and the angle is fixed by locking nuts to ensure that the sensitive surface of the sensor is perpendicular to the explosion point after installation.

[0030] The technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings. This embodiment uses the case of a single deep hole sensor positioning and installation device module of 1m for illustration. Before construction, the maximum outer diameter of the 1-meter hole support 2 is determined according to the hole depth and diameter. The number of turntable components 3 on each combined frame is determined according to the positional relationship between the blast center and the test deep hole and the test plan, and then the rotation angle of each turntable component 3 is determined. Then, the sensor is installed on the turntable component 3 at a specific angle, and the 1-meter hole support 2 is numbered to determine the positional relationship of the 1-meter hole support 2 in the deep hole. During construction, the base 1 and the 1-meter hole support 2 located at the bottom are first combined together with bolts and nuts. The wire rope 12 is tied and fixed in the wire rope 12 groove of the 1-meter hole support 2. The assembled device is placed into the opening of the deep hole 4 (see construction steps). Figure 1 At the opening of the fourth deep hole, the pre-set 1-meter-long internal support bracket is then assembled together using screws, nuts, and steel wire rope 12. Simultaneously, the sensor wiring harness is organized and bundled (see construction steps). Figure 2After installation, lower the entire structure by 1 meter and then install the next 1-meter in-hole assembly bracket (see construction steps). Figure 3 This process continues until all 1-meter borehole support units are installed. At this point, the two steel wire ropes 12 of the base 1 are outside the deep hole, and the orientation of the entire device can be adjusted by lifting the steel wire ropes 12. Finally, deep hole pressure grouting is performed to fill the deep hole with filling material. This invention solves the problem of deep hole explosion sensor installation and positioning. The modular design allows for series assembly according to different working conditions. The base 1 and the borehole support 2 are connected by studs and nuts (see figure: connection between base 1 and assembly), and the borehole support 2 is connected by screws and nuts (see figure: connection between assemblies). This effectively positions the sensor and facilitates rapid assembly. The lightweight design of the borehole support 2 facilitates construction operations. The rotation angle of the turntable assembly 3 allows for convenient and quick precise sensor installation. For the same working condition, all components can be uniformly processed and installed before deep hole filling, making the deep hole explosion testing process more economical, convenient, and efficient. This invention solves the problem of convenient and rapid sensor deployment in deep holes and is suitable for widespread promotion and application.
