TECHNICAL FIELD

[0001] The application relates to the technical field of downhole detection, in particular to a mine water downhole sampling and detection device. BACKGROUND

[0002] The core function of the downhole water quality detection device is to conduct in-situ, real-time and continuous water quality parameter monitoring at the key nodes of mine underground water flow, so as to provide data support for safety production and environmental protection.

[0003] In the downhole operation environment, efficient management and safety monitoring of underground water are key links to ensure production safety. Due to the complex geological conditions in the mine, underground water often exists in the form of multiple tributaries. These tributaries will eventually converge at a specific location and form a concentrated flow with a certain flow direction, which will eventually lead to the downhole sump. However, it is this complex converging flow area (hereinafter referred to as "complex converging water") before the tributaries converge and flow to the sump that brings difficulties to real-time and accurate detection of water quality.

[0004] The existing detection device is prone to form a dense sulfate crystalline film or floating material on the surface of the flowing water body under the disturbance of the converging flow and the evaporation effect due to the rich sulfate and other minerals in the underground water. These substances have strong adhesion and will affect the sampling accuracy when sampling the water, resulting in inaccurate data. The downhole water inflow is significantly affected by geological structures, mining activities, rainfall infiltration and other factors, and the water flow at the converging point may fluctuate significantly in a short time (from a trickle to a sudden flood). The device is difficult to adapt to such extreme instability. SUMMARY

[0035] The inside of the isolation net 411 is fixedly connected with the rope body 402 at the shaft part.

[0036] As Figure 2 and Figure 6As shown, the device is installed on the wall of the catchment area at the confluence of the tributaries, the lowest point of the screw jack 100 does not contact the ground surface of the catchment area, the tributary area arrow is a flow guide diagram of the confluence of the tributaries, after the tributary area is concentrated through the catchment area, the flow direction is unified to the downhole sump, since fewer people are active in the catchment area, during installation, the baffle 306 is partially oriented towards the tributary flow area, from which the installation guide is completed, due to the particularity of the complex catchment flow area before the flow to the sump, under normal flow conditions, the carrier 301 is higher than the water surface, the motor 305 works to drive the gear 302 to work, the gear 302 drives the chain 303 to run, at this time the chain 303 drives the auxiliary mechanism 400 inside the carrier 301 to move downward towards the confluence of the tributaries, the L rod 401 gradually lowers on the surface of the chain 303, when the L rod 401 drives the water storage cylinder 410 to run to the guide block 304 inside the carrier 301, the water storage cylinder 410 tilts, at the same time the end of the water storage cylinder 410 starts to contact the water surface, at this time due to the gravity of the water storage cylinder 410, the annular ring 405 on the surface of the blocking ball 404 fits the end of the water storage cylinder 410, at the same time the isolation net 411 inside the water storage cylinder 410 is in a relatively horizontal state at this time, it has not been stretched, when the water storage cylinder 410 contacts the water surface while tilting, the end of the water storage cylinder 410 is less contaminated by the sulfate salt crystallization film or floating objects on the surface of the water body, at the same time, the movable piece 413 is similar in shape to the tapered port of the water storage cylinder 410, but its radius is larger than that of the tapered port of the water storage cylinder 410, when the water storage cylinder 410 tilts into the water, the movable piece 413 is oriented towards the tributary flow direction, further protecting the end of the water storage cylinder 410, the clumps of floating objects in front of the movable piece 413 are broken up, floating objects will be adsorbed on the surface of the movable piece 413 due to viscous drag, and turbulent wakes will be generated behind, breaking up large floating objects such as crystallization films under the action of turbulent shear force, making it more difficult for impurities on the turbulent water surface to enter the interior of the water storage cylinder 410, when the water storage cylinder 410 tilts into the water body, the blocking ball 404 and the annular ring 405 are separated from the water end of the water storage cylinder 410 and sink towards the lower layer of the tributary, when the chain 303 pulls the water storage cylinder 410 back into the carrier 301, the annular ring 405 will fit the end of the water storage cylinder 410 to seal it, at this time the end of the water quality sensor 412 contacts the sampled water, at this time, due to the movement of the annular ring 405 towards the water quality sensor 412, the isolation net 411 gradually changes from a stretched umbrella shape to a flat shape, when the isolation net 411 is completely reset, the middle gap becomes smaller, and under the recovery condition, it assumes the shape of a spider web, isolating large rocks that enter the water storage cylinder 410, reducing damage to the vulnerable parts of the water quality sensor 412 when the water storage cylinder 410 moves, the data detected by the water quality sensor 412, such as cleanliness, pH, etc., is received by the input module of the PLC, then the PLC transmits the signal to the remote computer,The data is uniformly collected by personnel.

[0037] Second working principle: That is, referring to Figure 3 As shown, Figure 3 In the environment of large groundwater inflow, the water flow of the catchment area fluctuates greatly, and the turbulent water flow will impact the baffle 306 on the surface of the carrier 301. In the case of excessive water flow, the lead screw elevator 100 drives the bottom plate 201 to immerse the opening below the carrier 301 in the tributary water body. The carrier 301 retains air inside, and the motor 305 works to send the auxiliary mechanism 400 into the water body collected by the tributary, so that it still performs sampling and detection processing on the lower layer of water in the case of turbulent water flow and large water inflow. The auxiliary mechanism 400 moves from the water to the water-free space inside the carrier 301 to collect data, improving the accuracy of detection. If the underground tributary contains a large amount of viscous silt, the surface of clay minerals is negatively charged, and by adsorbing Ca²⁺ / Mg²⁺ cations in water, it forms an "ion bridge" to make the particles coalesce into a network structure. The U-shaped part of the movable piece 413 will contact the rope body 402, causing the movable piece 413 to be limited by the annular ring 405 on the blocking ball 404 when the rope body 402 is lifted. At this time, the blocking ball 404 and the water storage cylinder 410 chamber are in an open state. When the water storage cylinder 410 enters the inside of the carrier 301, there is no detection water in the inside of the water storage cylinder 410, and the water quality sensor 412 cannot detect data. The water quality sensor 412 transmits the signal to the PLC controller, and then the PLC controller transmits the data to the remote computer. After the personnel know the situation, they will take emergency measures to deal with the underground water.

[0038] The contents not described in detail in the description belong to the prior art known to those skilled in the art, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
