Description

Technical Field

[0001] This utility model belongs to the technical field of water inrush monitoring and relates to a water inrush early warning and monitoring device for underground coal mines. Background Technology

[0002] Mine water inrush refers to the sudden influx of large amounts of groundwater into coal mine shafts due to factors such as tunnel breaches, water-rich karst caves, or water-accumulated old tunnels. It is one of the major hazards in coal mine production. If not handled promptly, the inrush can flood the mine shafts in a short time, endangering the safety of underground workers and severely damaging mine production equipment. Therefore, it is necessary to monitor changes in underground water sources and promptly investigate and address the risk of water inrush.

[0003] Conventional water inrush monitoring technology is mainly contact monitoring technology, which includes monitoring and analyzing indicators such as water pressure, water quality, and stress of mine water sources. This buys time for mine water hazard prevention and control and has the characteristics of being fast, accurate, and economical.

[0004] CN204202655U discloses a real-time multi-parameter measurement device for mine water, comprising: an electrical signal measurement module, a laser measurement module, and a signal processing module. The electrical signal measurement module includes a temperature sensor, a pH sensor, a conductivity sensor, and a water flow rate sensor placed at the water inflow point, as well as an amplifier circuit for amplifying weak electrical signals. The laser measurement module includes a laser, a fluorescence probe, and a fluorescence spectrometer for generating and receiving fluorescence spectral signals. The signal processing module is an STM32 processor for processing the received electrical signals.

[0005] CN211328314U discloses a coal mine underground water inrush early warning and monitoring device, including an early warning and monitoring device body. The early warning and monitoring device body includes a cylinder and multiple sensors fixed and inserted into the cylinder. A filter is fixedly connected to one end of the cylinder. A circular groove is opened on the other side of the cylinder, and an internal gear ring is rotatably fitted in the circular groove. A filter screen is fixedly connected to the side of the internal gear ring away from the filter. A shielding box with an open bottom is fixedly connected to the bottom inner wall of the cylinder, and a drive motor is fixedly installed on one inner wall of the shielding box.

[0006] However, existing detection equipment for monitoring coal mine water inrush is prone to errors due to impurities in the water flow, reducing the accuracy of monitoring results. It can also easily lead to equipment blockage or even damage, failing to guarantee long-term effective detection efficiency and potentially causing major accidents in water inrush disaster prevention. Therefore, how to further improve the accuracy of water inrush monitoring has become an urgent problem to be solved. Utility Model Content

They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Those skilled in the art should understand that this utility model necessarily includes the necessary pipelines, conventional valves and general pump equipment for achieving complete process, but the above content is not the main improvement of this utility model. Those skilled in the art can add layouts based on the process flow and equipment structure selection. This utility model does not make any special requirements or specific limitations in this regard.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] In one specific embodiment, this utility model provides a coal mine underground water inrush early warning and monitoring device, including a detection cylinder, a fixed support, and a monitoring host. The detection cylinder is connected to the fixed support, which fixes the entire monitoring device in the area to be monitored, and the position of the detection cylinder is adjusted so that it is fully immersed in the water source. The detection cylinder is internally equipped with a filtration component and a flow guiding component. The filtration component divides the detection cylinder into a raw water zone and a filtered water zone arranged sequentially along the axial direction. The flow guiding component passes through the raw water zone and the filtered water zone sequentially, so that after the water enters the detection cylinder, it first passes through the raw water zone under the action of the flow guiding component, is filtered and purified by the filtration component, and then enters the filtered water zone before being discharged. A first water quality detection component and a second water quality detection component are respectively installed in the raw water zone and the filtered water zone for independently monitoring the water quality in the respective zones. An alarm component and an image acquisition component are installed on the fixed support. The alarm component is used to issue a water inrush early warning. The image acquisition component is used to acquire image information so that personnel can comprehensively analyze the environmental status of the area to be monitored and the water inrush situation. The monitoring host is communicatively connected to the first water quality detection component, the second water quality detection component, the alarm component, and the image acquisition component. The first water quality detection component, the second water quality detection component, and the image acquisition component upload various types of detection data to the monitoring host to determine whether a sudden water inrush has occurred and trigger the alarm component to issue a corresponding alert.

[0036] In some embodiments, the fixed bracket is provided with a movably connected lateral adjustment assembly and a longitudinal adjustment assembly. The lateral adjustment assembly includes a first adjustment seat and a plurality of lateral adjustment rods, and the longitudinal adjustment assembly includes a second adjustment seat and a plurality of longitudinal adjustment rods. The first adjustment seat is fixed to the fixed bracket. One end of each lateral adjustment rod is movably connected to the first adjustment seat and the other end is fixedly connected to the second adjustment seat. One end of each longitudinal adjustment rod is movably connected to the second adjustment seat and the other end is fixedly connected to the detection cylinder. In application, the horizontal position of the detection cylinder is first adjusted using the first adjustment seat and the lateral adjustment rods, and then the vertical position of the detection cylinder is adjusted using the second adjustment seat and the longitudinal adjustment rods to reach the target detection position. For example, the lateral adjustment rods and longitudinal adjustment rods in this invention can respectively adopt lateral lead screws and longitudinal lead screws commonly used in the art. The first adjustment seat and the second adjustment seat are independently equipped with drive motors, and the drive motors are connected to the lateral lead screws or longitudinal lead screws in a transmission connection method commonly used by those skilled in the art, for driving the lateral lead screws or longitudinal lead screws to extend or retract, thereby achieving position adjustment. Furthermore, the drive motor can also be remotely controlled using software, hardware, and electromechanical control technologies known to those skilled in the art.

[0037] Furthermore, the outer wall of the detection cylinder is also equipped with a displacement detection component, which is communicatively connected to the monitoring host to upload the displacement data of the detection cylinder during the position adjustment process to the monitoring host. The staff can grasp the position information of the detection cylinder and adjust the detection cylinder to monitor the water quality of water sources at different depths according to actual detection needs.

[0038] In some embodiments, the filtration assembly includes a plurality of filter plates, which are arranged side-by-side at intervals along the axial direction of the detection cylinder and are detachably connected to the inner wall of the detection cylinder. The filter plates can filter out sediment from the purified water source, and after the monitoring work is completed, the filter plates can be disassembled and cleaned to avoid clogging and affecting the detection effect. This invention, by monitoring the water quality of two water samples before and after filtration, can provide a more comprehensive understanding of changes in the water source, reduce errors caused by insignificant changes in the surface water, and improve detection accuracy. This invention does not specifically limit the detachable connection method between the filter plates and the detection cylinder; it can employ common methods used by those skilled in the art, such as snap-fit ​​connections, bolt connections, or keyed connections.

[0039] In some embodiments, the inlet end of the detection cylinder is provided with a flow guide shroud, which has several inlet holes. These inlet holes connect to the raw water zone, allowing water to enter the raw water zone within the detection cylinder through the inlet holes. Under the action of the flow guide assembly, the water flows through the filter assembly into the filtration zone and is then discharged. The flow guide assembly includes a rotating shaft and spiral blades. The rotating shaft passes sequentially through the raw water zone and the filtration zone along the axial direction of the detection cylinder and connects to the inner wall of the detection cylinder. The spiral blades are disposed on the outer periphery of the rotating shaft. The detection cylinder is also necessarily equipped with a drive mechanism necessary for the complete process, used to drive the rotating shaft to rotate, thereby driving the spiral blades to guide the water flow, ensuring a uniform distribution of different water components in the raw water zone and the filtration zone. Then, the first and second water quality detection components are used to detect different parameters of the water source quality to determine whether a sudden water inrush has occurred.

[0040] In some embodiments, the first and second water quality detection components each independently include a plurality of water quality sensors. These sensors are equidistantly spaced on the detection cylinder and extend below the liquid surface in the raw water zone or filtration zone to collect data. Further, the water quality sensors include temperature sensors, pH sensors, conductivity sensors, ion concentration sensors, oxidation-reduction potential sensors, odor sensors, or flow rate sensors. Both the first and second water quality detection components employ combinations of multiple water quality sensors to obtain various water quality parameters, such as water flow temperature, pH value, conductivity, ion concentration, oxidation-reduction potential, water source odor, and water flow rate, etc., to comprehensively and holistically assess changes in the water source quality. The ion concentration of the water source can be Na+, as is well known to those skilled in the art. + K + SO4 2- NO3 + Ca 2+ Mg 2+ or Cl - Plasma concentration.

[0041] In some implementations, the alarm component includes an audible and visual alarm that is immediately triggered upon detecting a sudden influx of water, alerting staff to evacuate promptly and take appropriate measures to ensure the safety of underground workers and the safe operation of equipment.

[0042] In some embodiments, the image acquisition component is covered with a waterproof protective cover to protect it from moisture or damage, enabling it to acquire images for extended periods and ensuring the long-term stability of the monitoring work.

[0043] In some implementations, the monitoring host is equipped with a display that can intuitively display various water quality parameters and image information detected. When no sudden water inrush is detected, the display shows a normal water source indication. Once a sudden water inrush is detected, the display shows a danger warning and simultaneously activates the alarm component to issue a synchronous warning down in the well.
