Abstract
Description
Technical Field
[0001] This application relates to the field of downhole observation equipment technology, and in particular to a downhole borehole water inflow hydrological observation device. Background Technology
[0002] Hydrological information such as borehole water inflow and temperature is one of the important factors for assessing the deep hydrogeological conditions of the exploration area and evaluating potential deep water hazards and environmental risks. Anomalies in water inflow and temperature may indicate the presence of water-conducting faults or karst channels in deep rock strata. In most deep mining exploration areas, as the exploration depth increases, water inflow will be revealed during borehole construction. The water flows out of the borehole and along temporary drainage ditches in the roadway to be discharged into the main canal.
[0003] Currently, hydrological observation within the pit mainly involves installing fixed weirs in the main channel (measured using handheld calipers). Borehole water inflow observation typically uses a fixed-volume bucket to collect the water flow, timing the time required to fill the bucket to calculate the water inflow per unit time. This method is labor-intensive, inefficient, and inaccurate, and cannot provide real-time monitoring of borehole water inflow. Utility Model Content
[0004] To address or partially address the problems existing in related technologies, this application provides a downhole borehole water inflow hydrological observation device, applicable to roadways and ditches of different sizes, capable of accurately measuring borehole water inflow, hydrology, and other hydrogeological conditions.
[0005] The first aspect of this application provides a downhole borehole water inflow hydrological observation device, including: a movable trough, a thermometer and a water velocity sensor installed in the movable trough, a movable filter and a scale installed at the water inlet of the movable trough, a set of movable troughs can be stretched or contracted along the length direction through an adjustable connecting mechanism, and after adjustment, they are fixed by locking bolts, and the bottom of the movable trough is provided with fixing rivets.
[0006] The adjustable connection mechanism includes a locking bolt and several connection holes equidistantly opened on the side wall of the movable groove. The movable groove forms a nested structure, and the overlapping area is fixedly connected based on the locking bolt passing through the connection holes.
[0007] The adjustable connection mechanism includes a parallel slide rail installed inside the movable groove and a slider installed on the corresponding edge of another movable groove and matching the parallel slide rail. The slider is embedded in the parallel slide rail and can slide freely along the slide rail. Connection holes are provided on the movable groove of the slide rail and the slider.
[0008] The inner edge of the water inlet is equipped with slots that match the frame of the movable filter screen, and the frame of the movable filter screen is embedded in the slots.
[0009] The movable filter screen has an accordion-style folding structure, and the folded part can expand or contract according to the width of the water inlet, with the maximum stretch matching the maximum width of the water inlet.
[0010] The technical solution provided in this application may include the following beneficial effects:
[0011] This application provides a hydrological observation device for borehole water inflow in underground mines. Through an adjustable connection structure, the width of the device can be flexibly adjusted according to the actual size of the roadway drainage ditch, making it suitable for drainage ditches of different specifications. This improves the applicability of the device in complex underground environments and allows for wide application in various roadway hydrological observation scenarios.

It can be reused at multiple working points, demonstrating good practicality.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0022] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0023] like Figure 1-3 The device shown is a downhole borehole water inflow hydrological observation device, comprising: a first movable slot 1, a second movable slot 2, a movable filter screen 6, a scale 5, fixing rivets 7, a thermometer 3, and a water velocity sensor 4. The first movable slot 1 and the second movable slot 2 are rectangular structures with openings at the top and sides, respectively, and the openings are correspondingly positioned. The first movable slot 1 is fitted over the second movable slot 2 to form a detection box. Handles 8 are provided at both ends of the detection box, and fixing rivets 7 are provided at the bottom for securing the device to the water channel. The detection box has an inlet along the water flow direction, and scales 5 for data reading are installed on both sides of the inlet. A thermometer 3 is installed inside the first movable slot 1 for hydrological measurement, and a water velocity sensor 4 is installed inside the second movable slot 2 for measuring the borehole water inflow velocity.
[0024] The inner edge of the inlet is equipped with slots that match the frame of the movable filter screen 6, and the frame of the movable filter screen 6 is embedded in the slots. The movable filter screen 6 has an accordion-style folding structure. The main body of the filter screen is a metal mesh or a high-strength nylon mesh, and the edge is a metal strip frame. The folded part can expand or contract according to the width of the inlet, and the maximum stretching amount matches the maximum width of the inlet.
[0025] Multiple connecting holes are equidistantly opened on the side walls of the first movable groove 1 and the second movable groove 2, forming a nested structure. When the second movable groove 2 is completely fitted into the first movable groove 1, the device is at its minimum measuring width. The movable groove is stretched along the length direction by the handle 8. After adjustment, the overlapping area is fixedly connected by the locking bolt 9 through the connecting hole.
[0026] Furthermore, to facilitate smoother and more convenient adjustment of the device's extension and retraction, parallel slide rails, specifically U-shaped slide rails, are welded to the two sides of the first movable groove 1. Slider blocks, specifically T-shaped sliders, are welded to the corresponding edges of the second movable groove 2 to match the slide rails. These sliders are embedded within the slide rails and can slide freely along them to achieve spacing adjustment. An anti-detachment structure is provided at the maximum adjustment point of the slide rails to ensure they do not detach during adjustment. Multiple connecting holes are opened on the outer wall of the first movable groove 1, with the spacing set according to the required adjustment precision. A corresponding connecting hole is also opened in the middle of the slider. After adjustment, the slider is fixed by passing a locking bolt 9 through the aligned connecting hole to prevent sliding displacement.
[0027] The specific working process is as follows: 1. Based on the size of the tunnel ditch, the first movable groove 1 and the second movable groove 2 are stretched to ensure that the length of the device is consistent with the width of the ditch. The devices are then locked and secured around the perimeter with fixing rivets 7. 2. A filter screen is installed at the inlet of the movable groove to prevent debris from entering the groove and attaching to the thermometer 3 and water velocity sensor 4, thus affecting the measurement results. 3. The temperature change of the borehole water is monitored daily by observing the reading of the thermometer 3. The increase or decrease in water volume is calculated and monitored using a ruler and water velocity sensor 4. This device can be disassembled and reused at other work sites after the completion of one operation.
[0028] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
