Abstract
Description
Technical Field
[0001] This invention relates to the field of pipeline measurement equipment technology, and in particular to a horizontal directional drilling pipeline rotary measuring instrument and its usage method. Background Technology
[0002] During pipeline laying, when the pipeline is driven into the ground, it will twist after being driven into the ground. If the twist angle exceeds a certain degree, it will cause damage to the pipeline due to severe deformation, reducing its service life. Therefore, it is necessary to monitor the rotation angle of the pipeline during pipeline laying. However, in the existing technology, most of the rotation angle detection devices are benchtop detectors, which cannot detect the rotation angle of the buried part of the pipeline.
[0003] Existing horizontal directional drilling (WDD) pipe-crossing rotary measuring instruments are mostly benchtop instruments or instruments installed on the inner wall of the pipe. They cannot detect the rotation angle of the buried part of the pipe and lack a support and limiting structure, resulting in poor protection. This means that the pipe does not have good support and stability when measuring bends, and its pressure resistance is poor. When the medium inside the pipe passes through, the impact force brought by the medium can easily damage the measuring instrument due to excessive pressure, affecting the test results.
[0004] Existing horizontal directional drilling (WDD) pipe-crossing rotary measuring instruments are mostly benchtop models or have measuring devices installed on the inner wall of the pipe. They cannot detect the rotation angle of the buried pipe section and lack a support and limiting structure, resulting in poor protection. This makes the pipe unsupported and unstable when measuring bends, and the pressure resistance is poor. When the medium flows through the pipe, the impact force from the medium can easily damage the measuring instrument due to excessive pressure, affecting the test results. This solution addresses these issues by setting an adjustable support structure that can be adjusted according to the inner diameter of the pipe, fixing the measuring instrument inside the pipe. At the same time, a flow-through pressure-reducing structure is set in the middle of the measuring instrument. When the medium flows in the pipe, it can directly pass through the measuring instrument and the impact force of the flowing medium is reduced, thus effectively protecting the measuring instrument. Summary of the Invention

[0016] As a preferred embodiment, a method for using a horizontal directional drilling pipe-crossing rotary measuring instrument includes the following specific steps: S11: Install the measuring instrument body at the predetermined position on the pipeline, and perform three-stage telescopic adjustment via the electric adjustable telescopic rod: first, perform coarse adjustment to adapt to the pipeline inner diameter range, and then achieve ±0.1mm level precision positioning through the fine adjustment knob. Check that the mounting base and support pad form a 360° circumferential fit. The anti-slip rubber texture improves the fixing friction by 50% through nano-level friction enhancement technology. At the same time, the support indicator light displays the three-color status in real time. S12: The pressure sensor is activated to monitor the support force in real time. The two-stage buffer structure of the pressure-reducing spring telescopic rod achieves lateral impact force attenuation. When the medium flow rate exceeds the threshold, the first-stage spring absorbs 80% of the impact energy, and the second-stage gas-liquid mixing buffer chamber further dissipates the remaining energy. Combined with the gradient screen design of the permeable trough, it intercepts foreign objects while ensuring the flow of medium. S13: The data analyzer completes a three-stage configuration.

The data verification module adopts a dual-redundancy verification mechanism to ensure transmission integrity. Finally, an AES-256 encrypted 5G / LoRa dual-mode transmission channel is established through the wireless communication module. S14: After installing the angle sensor on the support base, the dual-axis gyroscope eliminates the zero bias error through a six-position calibration method. The magnetic field sensor, combined with the geomagnetic compensation algorithm, eliminates the ±3° environmental magnetic field interference. The temperature compensation module achieves wide temperature range accuracy compensation from -40℃ to 120℃ through a thermistor network.

S17: Establish a PDCA cycle maintenance system, check the screen permeability monthly, and use ultrasonic cleaning technology to remove deposits; perform zero-point calibration of the angle sensor quarterly, and achieve a calibration accuracy of ±0.01° through a standard angle generator; update the algorithm model of the data analyzer every six months, and improve data fusion efficiency through an online learning mechanism; check the integrity of the nano-hydrophobic coating of the protective bracket annually, and use a contact angle meter to evaluate the hydrophobic performance.
[0017] The beneficial effects of this invention are: 1. Existing horizontal directional drilling (WDD) pipe-crossing rotary measuring instruments are mostly benchtop instruments or have measuring devices installed on the inner wall of the pipe. They cannot detect the rotation angle of the buried part of the pipe and lack a support and limiting structure, resulting in poor protection. This makes the pipe lack good support and stability when measuring bends, and its pressure resistance is poor. When the medium passes through the pipe, the impact force of the medium can easily damage the measuring instrument due to excessive pressure, affecting the test results. This solution sets up an adjustable support structure, which can be adjusted according to the inner diameter of the pipe wall, and fixes the measuring instrument inside the pipe. At the same time, a flow-through pressure-reducing structure is set in the middle of the measuring instrument. When the medium flows in the pipe, it can directly pass through the measuring instrument and reduce the impact force of the flowing medium, thereby effectively protecting the measuring instrument. 2. Existing horizontal directional drilling (WDD) rotary measuring instruments used inside pipelines are susceptible to physical damage from internal wall pressure, friction, and impurities in the medium. The lack of protective measures exposes precision components directly to harsh environments, making them vulnerable to compression, wear, or corrosion, leading to increased equipment failure rates and shortened service life. This solution utilizes carbon fiber reinforced composite materials for the protective bracket, combining high strength with lightweight characteristics. Secure installation is achieved through fixing bolts, and the surface is coated with a nano-hydrophobic coating that effectively resists the erosion of moisture and corrosive media. Through structural innovation, a multi-layered protective barrier is constructed, significantly improving the equipment's resistance to pressure, wear, and corrosion, extending its service life, and ensuring the measurement accuracy and stability of precision components in harsh environments.

At the same time, the support indicator light (205) displays the three-color status in real time. S12: The pressure sensor (210) is activated to monitor the support force in real time. The lateral impact force is attenuated through the two-stage buffer structure of the pressure-reducing spring telescopic rod (209). When the medium flow rate exceeds the threshold, the first-stage spring absorbs 80% of the impact energy, and the second-stage gas-liquid mixing buffer chamber further dissipates the remaining energy. Combined with the gradient screen (208) design of the permeable trough (207), foreign objects are intercepted while ensuring the medium flow rate. S13: The three-stage configuration is completed in the data analyzer (201). First, synchronous data of temperature, pressure and flow are collected through a multi-channel sensor array. The central processing unit executes a noise reduction algorithm based on wavelet transform and data fusion with Kalman filtering. The algorithm acceleration module achieves millisecond-level response through FPGA hardware acceleration. The data verification module adopts a dual-redundancy verification mechanism to ensure transmission integrity. Finally, an AES-256 encrypted 5G / LoRa dual-mode transmission channel is established through the wireless communication module. S14: After installing the angle sensor (302) on the support base (301), the dual-axis gyroscope eliminates the zero bias error through the six-position calibration method, the magnetic field sensor combines the geomagnetic compensation algorithm to eliminate the ±3° environmental magnetic field interference, the temperature compensation module achieves wide temperature range accuracy compensation of -40℃ to 120℃ through the thermistor network, and the water seepage hole (402) of the protective bracket (401) adopts a biomimetic shark skin structure to achieve IP68 waterproof and dustproof rating while ensuring the flow of the medium; S15: After embedding the environmental detector (502) into the limiting slot (501), the three-dimensional environmental monitoring network is started. The temperature and humidity sensor uses a digital SHT35 chip to achieve ±0.1℃ accuracy measurement. The gas detection module monitors the concentration of harmful gases through an electrochemical sensor array. The air quality sensor uses the laser scattering principle to monitor PM2.5 / PM10 in real time. The microprocessor executes environmental trend prediction based on LSTM neural network. The storage module uses ferroelectric memory to ensure that data is not lost for ten years. The wireless module supports NB-IoT and Bluetooth 5.2 dual-mode communication. S16: During pipeline operation, the data analyzer (201) continuously performs multi-source data fusion analysis, achieves millisecond-level anomaly detection through edge computing, the electric adjustable telescopic rod (202) automatically adjusts the support force according to real-time pressure data, the angle sensor (302) detects changes in pipeline rotation angle through a dynamic threshold algorithm, and the environmental detector (502) monitors the operating environment parameters in real time. When an anomaly is detected, the communication and alarm unit triggers a three-level audible and visual alarm. S17: Establish a PDCA cycle maintenance system, check the permeability of the screen (208) monthly, and use ultrasonic cleaning technology to remove deposits; perform zero-point calibration of the angle sensor (302) quarterly, and achieve a calibration accuracy of ±0.01° through a standard angle generator; update the algorithm model of the data analyzer (201) every six months, and improve the data fusion efficiency through an online learning mechanism; check the integrity of the nano-hydrophobic coating of the protective bracket (401) annually, and use a contact angle meter to evaluate the hydrophobic performance.
