Description

Technical Field

[0001] This utility model relates to the field of deep hole engineering measurement and sensor installation technology, and in particular to a deep hole sensor orientation and positioning installation device. Background Technology

[0002] In engineering fields such as geological exploration, mining, underground pipe gallery, dam safety, foundation stability, landslide, displacement, and settlement monitoring, it is often necessary to install sensors in deep holes to achieve long-term monitoring of underground soil conditions, structural stress, and environmental parameters. The installation position accuracy and orientation accuracy of the sensors directly determine the validity of the monitoring data. If the sensors are tilted or oriented, it is easy to cause the monitoring data to be distorted (for example, the directional deviation of displacement sensors will misjudge the displacement direction, and the tilt of stress sensors will affect the stress acquisition and three-dimensional vibration monitoring), thereby affecting the judgment of engineering safety.

[0003] Currently, the orientation accuracy of deep hole sensors is difficult to guarantee during installation. Existing installation schemes mostly rely on a single benchmark (such as ground markings corresponding to the length of the hoisting rope) to determine the sensor orientation, lacking effective verification methods. Magnetic field interference from metal components inside the deep hole and lateral pressure from the soil can easily lead to orientation deviations, and these deviations cannot be detected and corrected in a timely manner.

[0004] Based on the above-mentioned technical problems, this utility model provides a deep hole sensor orientation and positioning installation device. Utility Model Content

[0005] The purpose of this invention is to provide a directional positioning and installation device for deep hole sensors to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a deep hole sensor orientation and positioning installation device, comprising: The frame is a cylindrical structure, and the top inner wall of the frame is provided with several sets of lifting points at equal intervals around the circumference; A spiral frame, which is fixed to the inner wall of the frame; The mounting bracket is located at the center of the frame and is fixed to the frame. The sensor to be installed is mounted on the mounting bracket. The calibration indicator assembly comprises two sets, which are symmetrically installed on both sides of the frame. A calibration element extends into the frame and is used to calibrate the position of the sensor.

[0007] According to the deep hole sensor orientation and positioning installation device provided by this utility model, the top of the frame is symmetrically provided with grooves, and the power device is engaged with the grooves to apply rotational power to the frame.

[0008] According to the deep hole sensor orientation and positioning installation device provided by this utility model, the number of lifting points is three sets, and the three sets of lifting points are arranged at equal intervals around the inner wall of the frame. The lifting points are hoisted by thin lead wire or thin steel wire rope.

[0009] According to the deep hole sensor orientation and positioning installation device provided by this utility model, the calibration indicator component includes an electronic compass and a glow stick, and the electronic compass and the glow stick are respectively mounted on the frame.

[0010] According to the deep hole sensor orientation and positioning installation device provided by this utility model, the mounting bracket and the frame are fixed together by a connecting rod.

[0011] According to the deep hole sensor orientation and positioning installation device provided by this utility model, the calibration component is a high-definition endoscope.

[0012] The present invention discloses the following technical effects: This invention effectively solves the problem of controlling sensor installation accuracy in deep hole environments through the synergistic effect of multiple structures. The cylindrical frame provides a stable installation foundation for the entire device, and the circumferentially spaced lifting points ensure uniform force distribution during hoisting, avoiding initial position deviation of the sensor due to hoisting tilt. Two sets of symmetrical calibration indicator components can provide real-time feedback on the attitude and position information of the device in the deep hole, facilitating timely adjustments by construction personnel and preventing device displacement. The mounting bracket is fixed at the center of the frame, ensuring that the sensor is always in the preset installation center area. Combined with the precise calibration of the calibration components, the error of the sensor installation position can be controlled within a very small range, ensuring that the sensor can accurately collect relevant data in the deep hole, providing reliable hardware support for monitoring work, and avoiding data distortion due to insufficient installation accuracy, which would affect the judgment and analysis of the deep hole environment. Compared to traditional deep-hole sensor installation methods, the structural design of this invention greatly simplifies the construction process. All components can be pre-assembled and tested on the ground, eliminating the need for complex on-site assembly inside the deep hole, thus reducing the difficulty and risks associated with working at heights and in deep holes. The lifting point design at the top of the frame facilitates hoisting; construction personnel only need to use the hoisting equipment in conjunction with the feedback from the calibration indicator component to position and lower the device, without the need for complex positioning equipment and cumbersome procedures. The use of calibration components allows for rapid verification of sensor positions, avoiding the repeated disassembly and adjustment required in traditional calibration methods, and shortening calibration time. Overall, this device integrates and optimizes multiple complex aspects of deep-hole sensor installation, reducing the operational difficulty for construction personnel, minimizing construction time, and significantly improving installation efficiency. It is particularly suitable for batch sensor installations or deep-hole monitoring projects with tight deadlines. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figures 1-2 This utility model provides a deep hole sensor orientation and positioning installation device, comprising: Frame 1, which is a cylindrical structure, has several sets of hanging points 4 evenly spaced around the top inner wall of the frame 1; Spiral frame 2, which is fixed to the inner wall of the frame 1; Mounting bracket 3 is located at the center of the frame 1 and is fixed to the frame 1. The sensor to be installed is mounted on the mounting bracket 3. The calibration indicator assembly comprises two sets, which are symmetrically installed on both sides of the frame 1. A calibration element extends into the frame 1 and is used to calibrate the position of the sensor.

[0019] Before construction, the assembly and debugging of all components of the device are completed. The sensor to be installed is precisely fixed on the mounting bracket 3, ensuring that the sensor is firmly connected to the mounting bracket 3 and that the initial posture meets the installation requirements. At the same time, the sensitivity and accuracy of the two sets of calibration indicator components are checked to ensure that they can normally provide orientation and positioning information. Subsequently, using several sets of lifting points 4 evenly spaced around the inner wall of the top of the frame 1, the entire device is slowly lowered into the deep hole using hoisting equipment. During the hoisting process, the two sets of symmetrically installed calibration indicator components are observed in real time, and the posture and position of the device are adjusted according to the indication information to ensure that the frame 1 remains vertical and the mounting bracket 3 is in the preset center installation area of ​​the deep hole. Once the device is lowered to the designated depth, hoisting is paused and the device position is initially secured. Then, the calibration piece is slowly inserted into frame 1 to precisely verify the position of the sensor mounted on the bracket. If the verification reveals a deviation in the sensor position, the connection structure between the mounting bracket 3 and frame 1 is finely adjusted based on feedback from the calibration indicator component until the calibration piece indicates that the sensor position fully meets the design requirements. Finally, the device is fixed in place, ensuring that the sensor is stably positioned in the deep hole. The entire construction process strictly follows the operating procedures to ensure installation quality and efficiency.

[0020] In a further optimized design, the top of the frame 1 is symmetrically provided with grooves 6, and the power device engages with the grooves 6 to apply rotational power to the frame 1.

[0021] The symmetrical grooves 6 on the top of frame 1 serve as a crucial interface for the precise and stable installation and positioning of the power unit. Once the power unit engages with groove 6, controllable rotational power can be applied to frame 1 via power output components (such as a gear set driven by a small motor or a hydraulic drive shaft). During deep hole sensor installation, if adjustments to the sensor's circumferential angle are needed (e.g., to ensure precise alignment of the sensor's detection direction with the target monitoring area within the deep hole), the power unit can drive frame 1 to rotate synchronously with the mounting bracket 3 and the sensor. Due to the symmetrical design of groove 6, the torque output by the power unit is evenly transmitted to frame 1, preventing frame 1 from tilting due to uneven force. Simultaneously, the engaging structure prevents the power unit from detaching from frame 1 during operation, ensuring the stability and safety of rotational adjustments. Ultimately, this allows for precise fine-tuning of the sensor's circumferential position, meeting the monitoring needs of different directions within the deep hole.

[0022] An angle sensor is installed on the top of frame 1 or on the power unit to monitor the rotation angle of frame 1 in real time and provide feedback to the ground construction personnel via a display screen. This ensures the accuracy of rotation adjustment and avoids inaccurate circumferential positioning of the sensor due to human judgment errors. Simultaneously, mechanical limit blocks or electronic limit switches are installed on both sides of the groove 6. When frame 1 rotates to the preset maximum angle, the power supply to the power unit is automatically cut off or a mechanical lock is triggered to prevent malfunctions due to operational errors.

[0023] In a further optimized design, the number of lifting points 4 is three sets, and the three sets of lifting points 4 are arranged at equal intervals around the inner wall of the frame 1. The lifting points 4 are hoisted by thin lead wire or thin steel wire rope.

[0024] Three sets of lifting points 4 are evenly spaced (120° apart) around the inner wall of frame 1, conforming to the principle of triangular stability and providing balanced lifting support for frame 1. During the lifting process, thin lead wires or thin steel wire ropes connect the three sets of lifting points 4 to the hooks of the lifting equipment. Since the force points of the three sets of lifting points 4 are symmetrically distributed, the weight of frame 1 and the sensor can be effectively distributed, preventing frame 1 from tilting or overturning due to uneven force distribution during single or double-point lifting. Thin lead wires / thin steel wire ropes are flexible and lightweight, which can adapt to the slight bending of the channel that may exist in the deep hole (such as small diameter deviations during deep hole construction), reducing lifting resistance, and can also provide feedback on the force on frame 1 through their own slight deformation (such as abnormal tension of the steel wire rope on one side, which can indicate that frame 1 is tilting).

[0025] In a further optimized design, the calibration indicator component includes an electronic compass and a glow stick 6, which are respectively mounted on the frame 1.

[0026] Adjust the levelness of the sensor using a level bubble.

[0027] An electronic compass is mounted on frame 1, which can monitor the horizontal azimuth and tilt angle of frame 1 in real time. It transmits the data wirelessly to a ground receiving device. Construction personnel use this data to determine if frame 1 is in the preset directional position and adjust the hoisting posture or power unit accordingly to ensure accurate sensor orientation. A glow stick 6 is installed in a conspicuous position on the outside of frame 1. Due to the dim lighting inside the deep hole, the visible light emitted by the glow stick 6 can be observed through a camera at the top of the deep hole or by handheld lighting equipment used by construction personnel. Its main functions are twofold: first, to assist in determining the position of frame 1 within the deep hole; and second, to assist in determining whether frame 1 is tilted by comparing the brightness of the two sets of glow sticks 6. Together with the electronic compass, this forms a dual calibration system of "electronic data + visual observation," improving calibration reliability.

[0028] In a further optimized design, the mounting bracket 3 is fixed to the frame 1 by a connecting rod.

[0029] The solution was further optimized by using a high-definition endoscope as the verification component.

[0030] The high-definition endoscope serves as a calibration tool. Its core function is to allow direct observation of the sensor's installation position and orientation by extending into frame 1 through the top of the deep hole, and to capture images through a high-definition camera and transmit them to a ground display screen for construction personnel to perform precise calibration.
