Abstract
Description
Technical Field
[0001] This utility model relates to the field of data acquisition technology, and in particular to a fixed device for collecting parameters of water inrush in boreholes in mine floor. Background Technology
[0002] Coal mine floor water inrush is a major underground safety hazard, directly threatening mine production and personnel safety. Firstly, water inrush can rapidly flood the working face, causing equipment damage and even casualties. Secondly, a water inrush requires shutdown for investigation and remediation, with daily losses for a single mine reaching hundreds of thousands of yuan, and the remediation period often lasting several months. Furthermore, water inrush can cause a drop in the groundwater level, affecting surrounding water resources, and highly mineralized water inrush can pollute the underground working environment, increasing subsequent treatment costs. Therefore, one of the core needs of mines is to predict water inrush risks in advance and reduce the probability of accidents. Existing water inrush detection devices are insufficient to meet the comprehensive, stable, and real-time monitoring needs of mines. On the one hand, most devices only monitor water pressure and water level, lacking key parameters such as water quality, lithology, and fissures, making it impossible to comprehensively judge the precursors of water inrush. On the other hand, the high humidity, high dust, and strong electromagnetic environment underground can easily cause sensor signal drift, and most devices do not meet the explosion-proof standards for coal mines, posing safety hazards. In addition, existing devices lack backup power design, resulting in data loss after power failure, and transmission mostly relies on a single wired method. Data cannot be transmitted in real time after the underground wiring is damaged. At the same time, there are no standardized interfaces for each module, requiring modification to adapt to different borehole diameters. Underground maintenance is frequent and costly. Therefore, this utility model improves the existing equipment to address the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example: See Figures 1 to 6 This utility model discloses a fixed device for collecting parameters of water inrush from a borehole in a mine floor. It includes a ground surface 1, a detection hole 2 below the ground surface 1, a hole cover 3 installed and fixed at the opening of the detection hole 2, a support 4 horizontally mounted above the hole cover 3, a through hole on the hole cover 3, and a detection mechanism housing 5 inserted into the through hole. The detection mechanism housing 5 is characterized in that: multiple folding components are evenly spirally installed and fixed from top to bottom inside the detection mechanism housing 5, a group of detector modules are installed and fixed on the folding components, a hoisting component is provided on the support 4, and a sealing component is provided below the hole cover 3.
[0017] In this utility model, to solve the problems of single detection indicators, difficult maintenance, and water seepage safety in existing devices, the following technical solution is adopted: The hoisting assembly includes a reel 6, which is rotatably mounted and fixed to the top of the support 4. A motor 7 is connected and fixed to one side of the reel 6, and the motor 7 is mounted and fixed to one side of the top of the support 4. A steel cable 8 is wound around the outer side of the reel 6, and the lower end of the steel cable 8 is connected to the middle of the top surface of the detection mechanism housing 5. The detector module group includes a water level detection module housing 9, which contains an ultrasonic water level sensor. A bottom lithology detection module housing 10 is located at the lower angle of the water level detection module housing 9. The bottom lithology detection module housing 10 contains a portable gamma ray logging instrument, an acoustic logging probe, and a data acquisition card. A bottom stratum fracture detection module housing 11 is located further below the bottom lithology detection module housing 10 at a certain angle. The bottom stratum fracture detection module housing 11 contains a high-definition borehole imager, an acoustic flaw detector, and an image acquisition device. The data collection and processing unit includes a rock stratum mechanical parameter acquisition module housing 12 located at an angle below the bottom rock stratum fracture detection module housing 11. The rock stratum mechanical parameter acquisition module housing 12 houses a fiber optic strain sensor, a piezoelectric stress sensor, and a signal amplification circuit. Further below the rock stratum mechanical parameter acquisition module housing 12, at a certain angle, is a water quality detection module housing 13. The water quality detection module housing 13 houses an ion-selective electrode array, a conductivity sensor, a glass pH electrode water sample pretreatment unit, and a signal conditioning circuit. Below the water quality detection module housing 13, at an angle, is a water pressure and temperature detection module housing 14. The water pressure and temperature detection module housing 14 houses an immersion-type water pressure sensor, a platinum resistance temperature sensor, and a signal conditioning circuit. This device features multi-parameter fusion analysis capabilities. The data processing module, using an STM32H743 chip, collects and fuses data on lithology, fractures, and water quality for analysis. Compared to existing single-parameter monitoring, this results in a higher accuracy rate for predicting water inrush risks.
[0018] In this utility model, the water level detection module shell 9, the bottom lithology detection module shell 10, the bottom stratum fracture detection module shell 11, the stratum mechanical parameter acquisition module shell 12, the water quality detection module shell 13, and the water pressure and temperature detection module shell 14 are all fixed with folding components on the back and connected and fixed to the detection mechanism shell 5 through the folding components. The layered installation layout is more reasonable. The modules are arranged in layers according to the parameter acquisition requirements. The bottom layer contacts the water body, the middle layer fixes the stratum, and the upper layer is processed outside the hole. This ensures that the sensor can directly contact the monitored object and avoids the interference of water body and stratum on the data processing / transmission module. At the same time, the movable slide rail design realizes full-section detection of the borehole and adapts to the needs of drilling at different depths.
[0019] In this utility model, the folding assembly includes a triangular plate 15. A front hinge seat 16 is rotatably connected to the acute angle at the bottom of the triangular plate 15, and the telescopic end of a hydraulic rod 17 is rotatably connected to the other acute angle of the triangular plate 15. The triangular plate 15 is provided with a clearance groove to cooperate with the telescopic end of the hydraulic rod 17. The other end of the hydraulic rod 17 is rotatably connected to a rear hinge seat 18. Both the rear hinge seat 18 and the front hinge seat 16 are fixed to the inner side of the outer shell 5 of the detection mechanism. This device adopts a modular and standardized interface design. Each module independently collects specific parameters and is connected to a shielded cable through a standardized interface. Modules can be flexibly added or removed according to the different drilling monitoring needs of the mine without the need for overall replacement, which greatly improves the versatility of the device.
[0020] In this utility model, the sealing assembly includes an outer ring airbag 19, the outer ring surface of which abuts against the inner wall of the detection hole 2. An installation ring is fixedly installed on the inner ring surface of the outer ring airbag 19, and an inner ring airbag 20 is fixedly installed on the inner wall of the installation ring. The inner ring surface of the inner ring airbag 20 abuts against the outer shell 5 of the detection mechanism. Both the outer ring airbag 19 and the inner ring airbag 20 pass through the hole cover 3 through a flexible hose and are connected to the air supply equipment. The airbag on the detection mechanism not only increases the stability of each module in the hole and avoids displacement and tilting, but also prevents water from gushing into the bottom plate due to changes in geological conditions during the operation of the device, thus playing a role in blocking water.
[0021] Working principle: First, power is supplied to the equipment. Then, the outer shell 5 of the detection mechanism is inserted into the detection hole 2. At this time, the folding assembly is in the retracted state. Then, the sealing assembly is inserted into the detection hole 2 and the hole cover 3 is closed. Then, the inflation device is started to inflate the outer ring airbag 19 and the inner ring airbag 20. The outer ring airbag 19 positions the mounting ring in the center position, and the inner ring airbag 20 fixes the outer shell 5 of the detection mechanism in the middle of the detection hole 2. After the device is installed, the hydraulic rod 17 is started, so that its telescopic end extends, thereby driving the triangular plate 15 to rotate around the front hinge seat 16, so that all detector modules extend. Then, all detectors and sensors are started to collect data at a preset frequency (which can be adjusted by ground command, such as water pressure once / minute, slit imaging once / hour), and the data is transmitted to the data center in real time. The processing equipment and data processing module fuse the received multi-parameter data (such as combining lithology and fracture data to determine the water-conducting channel), calibrate and store it to the SD card / Flash, and send it to the monitoring center through the transmission module; if a module fails (such as the sensor has no signal), the data processing module automatically sends a fault alarm to the monitoring center; then maintenance work is carried out. First, the detector module group is retracted according to the working principle of the above-mentioned folding component, and then the inner ring airbag 20 is quickly deflated. Since the inner ring airbag 20 is small in size, the deflation will be fast. Then the motor 7 is started, so that the winding wheel 6 rotates to wind up the steel cable 8, thereby lifting out the entire detection mechanism shell 5, and then quickly carrying out maintenance and replacement; after the device is used up, the power is disconnected, the pressure relief valve of the outer ring airbag 19 is opened, and the entire device can be retracted.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
