[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , Figure 2 As shown, a mine water inflow control and regulation device includes a main conveying pipeline 1, which can convey mine water. A branch pipeline 2 is fixedly connected to the side end of the main conveying pipeline 1. An adjustment component is provided at the connection between the main conveying pipeline 1 and the branch pipeline 2. The adjustment component is movably installed inside the main conveying pipeline 1. The adjustment component can adjust the flow rate at the input end of the branch pipeline 2 according to the water pressure. A filter component is detachably connected to the input end of the main conveying pipeline 1, and a valve is fixed on the input end of the main conveying pipeline 1.

[0019] The adjustment assembly includes a sliding block 6 that is fitted and slidably disposed inside the main conveying pipe 1. A compression spring 8 is fixedly connected between one side of the sliding block 6 and the cover plate 7. The cover plate 7 is fixedly connected to the side end of the main conveying pipe 1 by bolts.

[0020] An infrared distance sensor 11 is fixed to the side of the sliding block 6, and a sensor 10 is fixed to the side of the cover plate 7. The infrared distance sensor 11 and the sensor 10 are arranged opposite to each other. A battery pack 9 is fixed on the cover plate 7. The battery pack 9 is electrically connected to the infrared distance sensor 11 and the sensor 10 respectively. The sensor 10 can be wirelessly transmitted and electrically connected to an external alarm.

[0021] When the compression spring 8 is in its natural state, the sliding block 6 can completely seal the input end of the branch pipe 2.

[0022] The filtration assembly includes an outer layer filter 3, a middle layer filter 4, and an inner layer filter 5 arranged sequentially in the direction of water flow within the main delivery pipe 1. The filter screens of the outer layer filter 3, the middle layer filter 4, and the inner layer filter 5 are respectively fixed on a positioning component. The positioning component is detachably connected to the main delivery pipe 1. The gap between the filter screens of the outer layer filter 3, the middle layer filter 4, and the inner layer filter 5 is arranged to decrease sequentially.

[0023] The positioning component includes a positioning ring, in which a filter screen is fixed. The positioning ring can be inserted into the main conveying pipe 1 through a through hole and embedded in an arc-shaped groove. The through hole is fixed on the main conveying pipe 1, and the arc-shaped groove is fixed inside the main conveying pipe 1. An arc-shaped baffle is fixedly provided on the top of the positioning ring. The arc-shaped baffle is fixedly connected to the outer wall of the main conveying pipe 1 by bolts and seals the through hole.

[0024] The outer filter 3 uses a polyurethane elastic grid mesh, which can generate slight vibrations under the impact of water flow to shake off debris. The middle filter 4 uses a titanium alloy coated filter. The inner filter 5 has a nano-coating on its surface.

[0025] In actual work process:

[0026] Install the main delivery pipe 1 in the mine's water inflow channel, ensuring its inlet is located at the source of the mine's water inflow. Secure the cover plate 7 to the side wall of the main delivery pipe 1 with bolts, ensuring the regulating assembly is in place. Install the filter assembly at the inlet of the main delivery pipe 1 and secure it with the positioning assembly, ensuring the outer filter 3, middle filter 4, and inner filter 5 are installed sequentially and correctly positioned.

[0027] Install the flow control valve at the designated location on the side wall of the inlet end of the main delivery pipe 1, ensuring that it is located upstream of the filter assembly.

[0028] Connect the device to the power supply, allowing the battery pack 9 to power the infrared distance sensor 11 and sensor 10. Check that all connections are secure and ensure the device is well-sealed and leak-free. Activate the flow control valve and adjust it to the appropriate opening to prepare for water delivery.

[0029] When mine water enters the main delivery pipeline 1, it first passes through the outer filter 3. The polyurethane elastic grid mesh of the outer filter 3 vibrates slightly under the impact of the water flow, helping to prevent large particles from clogging the mesh and improving filtration efficiency. After this initial filtration by the outer filter 3, the water continues to flow through the middle filter 4, where a titanium alloy-coated filter further intercepts smaller particles. Finally, the water passes through the inner filter 5, where a nano-coated filter effectively removes tiny particles and impurities from the water, ensuring clean water quality.

[0030] When the mine water inflow is small, the water pressure in the main conveying pipe 1 is not enough to completely overcome the elastic force of the compression spring 8. Under the action of water pressure, the sliding block 6 opens a certain opening at the input end of the branch pipe 2 to ensure the delivery of mine water.

[0031] As the mine's water inflow increases, the water pressure in the main conveying pipeline 1 gradually rises. The sliding block 6 begins to slide gradually toward the cover plate 7, and the opening at the input end of the branch pipeline 2 gradually widens, thereby regulating the flow rate of the main conveying pipeline 1.

[0032] Infrared distance sensor 11 monitors the distance between sliding block 6 and sensor 10 in real time and transmits the data to sensor 10. When the detection distance exceeds the preset threshold, sensor 10 triggers an external alarm to remind staff to pay attention to changes in water flow and to intervene manually.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
