Description

Technical Field

[0001] The utility model relates to the technical field of coal mine water prevention and control devices, in particular to a coal mine geological engineering water prevention and control device. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine; when the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines are reasonable spaces excavated by humans when digging geological strata rich in coal. They usually include tunnels, shafts, and mining faces, etc. Nowadays, groundwater infiltration and other phenomena often occur during coal mining, resulting in flooding accidents in coal mines, which will threaten the lives of coal miners. Therefore, prevention and control work is of great importance and urgent practical significance.

[0003] After searching, the publication number CN214303942U proposes a coal mine geological engineering water prevention and control device, which is first placed at the flooded area of ​​the mine, and the set screws are tightened to fix the fixing plate to fix the device, and then the rotating handle is turned to rotate the screw rod, which can drive the power supply component to move up and down along the guide direction. The position of the power supply component corresponds to the scale on the transparent plate, and the dangerous water level of the alarm can be set accordingly. When the water at the flooded area of ​​the mine enters the sleeve from the water inlet, the floating plate in the sleeve floats up under the action of buoyancy. When the water level in the sleeve rises to the dangerous water level, the conductor on the floating plate contacts the power supply component, and the electrical circuit formed by the power supply component, the power line and the alarm light is connected, so that the alarm light flashes, and the water pump can be turned on to drain water. After a period of time, the water level drops below the dangerous water level, causing the floating plate to drop, the conductor to separate from the power supply component, and the alarm light goes out, and the water pump can be turned off at this time.

[0004] In the above patent, mine water enters the sleeve through the water inlet, but no filter is installed at the water inlet. Since the mine seepage water contains more impurities, when the impurities enter the sleeve, it is easy to cause the drainage pipe to be blocked and the water pump to be damaged during drainage, which is not conducive to people's use. Therefore, we propose a coal mine geological engineering water prevention and control device to solve the problems raised in the above background technology. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 to Figure 4 In the embodiment of the utility model, a coal mine geological engineering water control device includes a device shell 1, and mounting plates 7 are welded to the bottom ends of both sides of the device shell 1. One end of the mounting plate 7 is connected to a ground cone 8 by a thread. When in use, the coal mine geological engineering water control device is placed at a specified position, and then the ground cone 8 is rotated to make its cone section pass through the mounting plate 7 and fixed into the ground, so that the device shell 1 is stably fixed to the ground through the mounting plate 7. The bottom end of the side wall of the device shell 1 away from the mounting plate 7 is fixedly connected to a water inlet pipe 9 connected to the inside thereof. A transparent window 10 located at the top of the water inlet pipe 9 is installed on one side of the device shell 1, and scale lines are set on the surface of the transparent window 10. By observing the scale lines on the transparent window 10, the height of the water level in the mine at this time can be judged. A transparent observation window 11 is fixedly connected to one end of the top of the water inlet pipe 9, and the staff can view the precipitation of impurities inside the water inlet pipe 9 through the transparent observation window 11.

[0024] A filtering mechanism for filtering impurities in the mine water is provided at the end of the water inlet pipe 9, and the filtering mechanism includes an isolation cylinder 21 and a first filter screen 22.

The fixed rod 31 is rotatably connected to the middle of the side of the fixed rod 31 close to the first filter screen 22 through a bearing. One end of the rotating rod 32 passes through the first filter screen 22 and extends between the first filter screen 22 and the isolation cylinder 21. The surfaces of the rotating rod 32 on both sides of the first filter screen 22 are symmetrically provided with fixed The scraping brushes 34 are welded to both ends of the side walls of the ring 33 and the fixed ring 33, and the brush surfaces of the scraping brushes 34 are in contact with the side surfaces of the first filter screen 22. A rotating fan blade 35 located on the surface of the rotating rod 32 is welded to the side of one of the scraping brushes 34 close to the fixed rod 31. The surface of the rotating rod 32 is rotatably connected to the inside of the first filter screen 22.

[0026] During use, when the mine water flows through the first filter screen 22 to the rotating blades 35, the rotating blades 35 rotate under the impact of the mine water. The rotating blades 35 rotate, and the rotating rod 32 drives the scraping brush 34 to rotate accordingly, so that the scraping brush 34 continuously scrapes off the impurities attached to the surface of the first filter screen 22, so that the first filter screen 22 can maintain a stable filtering effect without manual cleaning, further improving the operating efficiency of the first filter screen 22 in filtering impurities in the mine water, thereby improving the practicability of the coal mine geological engineering water prevention and control device.

[0027] The device housing 1 is provided with a monitoring mechanism for monitoring the water level in the mine, the monitoring mechanism includes a floating plate 41, a conductor 42, an adjusting screw 43, a power supply 44 and an alarm component. The inner wall of the device housing 1 is symmetrically provided with moving grooves 12, the inside of the moving grooves 12 are both slidably connected to the two sides of the floating plate 41, the top of the floating plate 41 is fixedly connected to the conductor 42, the top surface of the device housing 1 is rotatably connected to the adjusting screw 43, one end of the adjusting screw 43 extends to the top surface of the device housing 1 for welding There is a rotating handle 45, the other end of the adjusting screw 43 extends to the interior of the device housing 1 and is rotatably connected to the top of the power supply 44 located above the conductor 42 through a bearing seat, and an alarm component is installed at one end of the top of the power supply 44. The alarm component includes a power-on wire 51 and an alarm 52. The top end of the power supply 44 is fixedly connected with the power-on wire 51, and the top surface of the device housing 1 is installed with the alarm 52 located on one side of the adjusting screw 43, and the end of the power-on wire 51 away from the power supply 44 passes through the device housing 1 and is electrically connected to the alarm 52.

[0028] During use, the operator rotates the rotating handle 45 to make the adjusting screw 43 move up or down. When the adjusting screw 43 rotates and moves, it drives the power supply 44 to move up or down. Then, according to the needs of use, the moving position of the power supply 44 corresponds to the scale line set on the surface of the transparent window 10, thereby setting the dangerous water level of the alarm. When the water in the mine water enters the device shell 1 through the water inlet pipe 9, the floating plate 41 floats along the moving groove 12 under the action of buoyancy. The water level inside the device shell 1 continues to rise, so that when the floating plate 41 rises to the dangerous water level, the top of the conductor 42 contacts the bottom of the power supply 44. At this time, the electrical circuit formed by the power supply 44, the power supply wire 51 and the alarm 52 is connected, so that the alarm 52 lights up and flashes to alarm.

[0029] The side wall of the device shell 1 away from the water inlet pipe 9 is provided with a drainage mechanism for discharging mineral water, and the drainage mechanism includes a water pump 61 and a drainage pipe 62. The side wall of the device shell 1 away from the water inlet pipe 9 is welded with a rectangularly distributed fixing frame 13, and the inner walls close to the fixing frame 13 are fixedly connected to the side wall of the water pump 61. The two ends of the water pump 61 are connected and installed with the drainage pipe 62. The drainage pipe 62 connected to one end of the water pump 61 extends to the interior of the device shell 1, and the end face of the drainage pipe 62 located inside the device shell 1 is bolted to a second filter screen 63, which is used to prevent fine impurities from entering the water pump 61 and causing damage to the water pump 61 over time.

[0030] During use, when the alarm 52 sounds, the water pump 61 is controlled to start, and the mineral water is pumped out by the drain pipe 62 through the second filter 63, and then discharged to a safe area. After a period of discharge, the water level drops below the dangerous water level. At this time, the floating plate 41 drops with the water level, thereby driving the conductor 42 to disconnect from the power supply 44, and the alarm 52 is extinguished and the water pump 61 is controlled to be closed, ending the drainage. The structure is simple and easy to use.

[0031] Working principle: When preparing to use the coal mine geological engineering water control device, first, the device housing 1 is fixedly installed in the designated position through the cooperation of the ground cone 8 and the mounting plate 7. Then, when the water level needs to be warned, the operator rotates the rotating handle 45 to make the adjusting screw 43 drive the power supply 44 to move upward. During the upward movement of the power supply 44, the scale line set on the surface of the transparent window 10 is observed. When the power supply 44 moves up to the alarm dangerous water level that needs to be set, the rotation of the rotating handle 45 can be stopped. When the mine water enters the water inlet pipe 9 through the filtering mechanism, the isolation cylinder 21 and the first filter screen 22 can filter the impurities in the mine water in turn, and at the same time Under the impact of the mineral water, the scraping mechanism is operated, so that the scraping brush 34 can continuously scrape the side of the first filter screen 22, thereby avoiding impurities from clogging the filter holes. When the mineral water continuously enters the device housing 1 through the water inlet pipe 9, the floating plate 41 floats up under the action of buoyancy. When it drives the conductor 42 to contact the power supply unit 44, the power supply unit 44 and the electric circuit formed by the power supply line 51 and the alarm 52 are connected, so that the alarm 52 sounds an alarm to control the operation of the water pump 61, and the mineral water is pumped out by the drainage pipe 62 through the second filter screen 63, and then discharged to a safe area. It is easy to use, can achieve early warning and drainage, and improve the safety of the coal mine shaft area.
