Description

Technical Field

[0001] This utility model belongs to the technical field of underground drainage systems in coal mines, specifically relating to a real-time monitoring intelligent underground drainage device for coal mines. Background Technology

[0002] During coal mining, multiple mine water pools are set up to collect and store water accumulated underground in order to ensure the underground environment. However, when the mine water pools are full, manual operation is required to start the motor to pump the water to the surface for discharge.

[0003] Coal mine drainage is a crucial aspect of ensuring safe production. Traditional drainage systems suffer from the following problems: low water level monitoring accuracy, making it impossible to control water levels accurately in real time, which can easily lead to water accumulation in roadways or frequent start-stop of drainage pumps; the start-stop of drainage pumps relies on manual intervention, resulting in slow response times and an inability to quickly address sudden water inrush situations; and high drainage energy consumption, lacking a linkage and adjustment mechanism with dynamic changes in mine water inflow. Utility Model Content

[0014] 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.

[0015] Please see Figures 1-3 As shown, this utility model provides a technical solution: a real-time monitoring intelligent drainage device for underground coal mines, including a drainage component, a monitoring and control component, and a lifting component. The drainage component and the monitoring and control component are both located on top of the lifting component. The lifting component includes a lifting plate 1, a base plate 2, and two sets of scissor lift frames, with the two sets of scissor lift frames located between the lifting plate 1 and the base plate 2. Each set of scissor lift frames includes a first support rod 3 and a second support rod 4. The first support rod 3 and the second support rod 4 are hinged together, and one end of the first support rod 3 and the second support rod 4 are respectively hinged to the lifting plate 1 and the base plate 2, and the other end is slidably connected to the base plate 2 and the lifting plate 1, respectively. A slider 5 is slidably arranged on the adjacent side of the hinged end of each first support rod 3 and the lifting plate 1, and a moving rod 6 is connected between two adjacent sliders 5. A cylinder 7 is arranged on the top of the lifting plate 1 near the monitoring and control component, and the output end of the cylinder 7 is connected to the moving rod 6.

[0016] like Figure 1 As shown, the drainage assembly includes a water pump 8, a water supply pipe 9, and a filter cartridge 10. The input end of the water pump 8 is connected to the water supply pipe 9, which is a flexible hose. The end of the water supply pipe 9 away from the water pump 8 is connected to the filter cartridge 10, and a wireless ball valve 11 is provided at the end of the water supply pipe 9 near the water pump 8. The filter cartridge 10 is provided with filter holes, and the filter cartridge 10 is threadedly connected to the water supply pipe 9, which facilitates the disassembly and cleaning of the filter cartridge 10.

[0017] The filter cartridge 10 is also equipped with a water level sensor. The water level inside the filter cartridge 10 is monitored by the water level sensor and the data is transmitted to the control unit 12 through the wireless communication module. After receiving the water level data, the control unit 12 analyzes and processes it through the processor and determines whether the preset water level line has been reached. When the water level does not reach the preset water level line, the microcontroller controls the cylinder 7 to start and automatically adjust the height of the drainage device to adapt to the liquid level depth of different mine water pools / accumulation points, ensuring that water at different depths can be effectively pumped out, avoiding incomplete drainage or equipment idling.

[0018] like Figure 2As shown, the monitoring and control component includes a control unit 12 and a power supply unit 13. The control unit 12 is located on one side of the power supply unit 13. The power supply unit 13 supplies power to the control unit 12, the water pump 8, the wireless ball valve 11, and the cylinder 7. The control unit 12 includes a microcontroller, a processor, and a wireless communication module. The microcontroller has a built-in intelligent control algorithm and performs logical judgments based on preset high and low water level lines (e.g., low water level line 0.1 meters, high water level line 0.3 meters). The microcontroller is wirelessly connected to the water pump 8 and the wireless ball valve 11 through the wireless communication module. The wireless ball valve 11 consists of a ball valve body, an electric actuator, and a wireless communication module. The output end of the electric actuator is connected to the valve core of the ball valve body, and the electric actuator is wirelessly connected to the control unit 12 through the wireless communication module. The wireless ball valve 11 receives instructions from the control unit 12 and rotates the valve core of the ball valve body through the electric actuator to realize the opening and closing of the water circuit or the flow regulation.

[0019] Both the power supply unit 13 and the power module use rechargeable intrinsically safe power supplies. The cylinder 7, water pump 8, control unit 12 and power supply unit 13 are all equipped with explosion-proof enclosures. The intrinsically safe power supply and explosion-proof enclosure design ensure the safe operation of the device in the mine and eliminate the risk of sparks and explosions.

[0020] The monitoring and control components also include a monitoring unit installed in the mine water tank. The monitoring unit includes a water level sensor and a power module. The water level sensor is wirelessly connected to the control unit 12. The power module supplies power to the water level sensor. The water level sensor monitors the water level of the mine water tank in real time and transmits the data to the control unit 12 through the wireless communication module.

[0021] The wireless communication module uses LoRa technology to realize wireless communication between the water level sensor and the control unit 12, and between the control unit 12 and the wireless ball valve 11.

[0022] The working principle and usage process of this utility model are as follows: During use, a water level sensor monitors the water level in the mine water tank in real time and transmits the data to the control unit 12 via a wireless communication module. After receiving the water level data, the control unit 12 analyzes and processes the data, determining whether the preset high and low water level lines have been reached. When the water level reaches the high water level line, the microcontroller immediately starts the water pump 8, which pumps water to the surface for discharge. The drainage volume is adjusted via a wireless ball valve 11. When the water level drops to the low water level line, the microcontroller stops the water pump 8, and simultaneously, the filter cartridge 10... The water level sensor inside the filter cartridge 10 monitors the water level in real time and feeds it back to the control unit 12. When the water level in the filter cartridge 10 does not reach the preset water level line, the microcontroller controls the cylinder 7 to start. The telescopic end of the cylinder 7 drives the moving rod 6 to move down. The movement of the moving rod 6 will drive the first support rod 3 and the second support rod 4 to unfold through the slider 5, thereby driving the lifting plate 1 to rise. This will adjust the height of the drainage device to adapt to the liquid level depth of different mine water pools / accumulation points, ensuring that water at different depths can be effectively pumped out, avoiding incomplete drainage or equipment idling.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
