Description

Technical Field

[0001] The utility model relates to the technical field of mine drainage, in particular to an automatic water pumping device for a mine tunnel water tank. Background Art

[0002] In a mining environment, water accumulation in tunnels is a significant problem. Its formation is typically due to a variety of factors. Groundwater infiltration is a common cause. Excavation of mine tunnels can disrupt the subsurface hydrogeological structure, allowing groundwater to flow continuously into the tunnels through rock fissures or loose strata. Furthermore, rainfall is a significant factor, particularly in shallow mines or areas with loosely sealed wellheads. Rainwater can flow into the tunnels through wellheads, ventilation ducts, or rock fissures. Water use in some aspects of the mine production process, such as cooling mining equipment and dust suppression sprays, can also lead to water accumulation in tunnels if the drainage system is inadequate.

[0003] Water accumulation in tunnels can pose numerous serious hazards to mine operations. First, large amounts of accumulated water can flood the working area, directly hindering normal mining operations and leading to production halts. Second, accumulated water can soak the tunnel walls and floor, weakening the rock formation's stability and increasing the risk of roof collapse, spalling, and other accidents. Furthermore, accumulated water can come into contact with metal equipment and rails within the tunnel, accelerating corrosion and rusting, shortening equipment lifespan and increasing maintenance costs and replacement frequency. Furthermore, accumulated water can mix with coal dust and rock dust within the tunnel to form slurry, deteriorating the working environment and affecting miners' vision and respiratory health. It also places an additional burden on the ventilation system, impacting underground air quality and airflow stability. Accumulated water in the tunnels tends to flow primarily into the water sump dug at the tunnel's base, and once the sump is full, it flows into the tunnel itself. Therefore, timely drainage of accumulated water from the sump is crucial.

[0004] In the prior art, a manually controlled water pump is usually used to discharge the accumulated water in the water tank. Although this method can solve the problem of water accumulation in the lane, the use of manually controlled water pumps to drain water is labor-intensive and not timely enough.

[0029] It should be noted that in the description of this utility model, “upper”, “lower”, “top”, “bottom”, orientation or position relationship is based on the attached Figure 1 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0030] In one embodiment, Figure 1 As shown, Figure 1This is one of the structural schematic diagrams of the automatic pumping device for mine tunnel water tank provided by an embodiment of the utility model. The automatic pumping device for mine tunnel water tank of this embodiment includes a drainage component and a control component for controlling the working condition of the drainage component according to the water level of the water tank.

[0031] The drainage assembly is provided with a drainage pipe 6 and a water pump 4 connected to the drainage pipe 6 and installed at the bottom of the water tank.

[0032] One end of the drain pipe 6 is connected to the water pump 4, and the other end of the drain pipe 6 is located on the ground. A check valve is installed between the drain pipe 6 and the water pump 4 to prevent water in the drain pipe 6 from flowing back into the water pump 4. The ultimate purpose of the check valve is to prevent water in the drain pipe 6 from returning to the water tank after the water pump 4 is turned off.

[0033] Specifically, the water pump 4 is a centrifugal pump or a submersible pump.

[0034] In this embodiment, a pressure water interface can also be set at the water outlet of the water pump 4, and pressure water can be added to the water pump 4 through the interface at any time to ensure that no air enters the pump housing of the water pump 4.

[0035] The control component is provided with a two-button 1, a first pressing component and a second pressing component that can press the two buttons of the two-button 1 according to the water level of the water tank respectively, and a QJZ-80 vacuum magnetic starter 2 that can control the start and stop of the water pump 4 according to the button pressing conditions of the two-button 1; the QJZ-80 vacuum magnetic starter 2 is electrically connected to the external power supply 3 and the water pump 4.

[0036] The two-link button 1 includes a first interface, a second interface, a third interface, a first button 11 that can connect the first interface and the second interface after pressing, and a second button 12 that can connect the second interface and the third interface after pressing. The first interface is connected to the 1# terminal of the QJZ-80 vacuum magnetic starter 2, the second interface is connected to the 2# terminal of the QJZ-80 vacuum magnetic starter 2, and the third interface is connected to the 9# terminal of the QJZ-80 vacuum magnetic starter 2.

[0037] The button pressing conditions of the dual button 1 include pressing the first button 11 , pressing the second button 12 , and pressing the first button 11 and the second button 12 simultaneously.

[0038] The QJZ-80 vacuum magnetic starter has five control line terminals, namely 1#, 2#, 8#, 13# and 9#, among which 1# line is the power line, 2# line is the self-protection line, and 9# line is the stop line. When 1# line and 2# line are connected, the QJZ-80 vacuum magnetic starter prepares to start. Then, when 2# line and 9# line are connected, the QJZ-80 vacuum magnetic starter controls the water pump 4 to start pumping water; when 1# line and 2# line are disconnected, the QJZ-80 vacuum magnetic starter performs self-protection and the water pump 4 continues to pump water; when 2# line and 9# line are disconnected, the QJZ-80 vacuum magnetic starter controls the water pump 4 to stop pumping water.

[0039] In this embodiment, the first button 11 and the second button 12 are both resettable buttons, which will automatically reset after the pressing force is released.

[0040] The first pressing assembly is used to press the first button 11 , and the second pressing assembly is used to press the second button 12 . The pressing water level of the first pressing assembly pressing the first button 11 is greater than the pressing water level of the second pressing assembly pressing the second button 12 .

[0041] If the first pressing assembly presses the water level high, then when the water level in the water tank rises, the second pressing assembly first presses the second button 12, and then as the water level continues to rise, the first pressing assembly presses the first button 11. When the water level gradually drops after drainage, the first button 11 is reset first, followed by the second button 12.

[0042] The automatic pumping device for the mine tunnel water tank of this embodiment, the QJZ-80 vacuum magnetic starter 2 can control the start and stop of the water pump 4 according to the working condition of the two-link button 1 pressed by the first pressing component and the second pressing component, thereby automatically starting or stopping pumping according to the water level in the water tank, which can reduce the manpower burden and ensure timely drainage.

[0043] In one embodiment, the control assembly is further provided with a U-shaped fixing rod 5 with an opening facing downwards, the U-shaped fixing rod 5 is located on the ground, and the U-shaped bottom of the U-shaped fixing rod 5 is parallel to the horizontal plane.

[0044] It should be noted that the bottom of the U-shaped fixing rod 5 of this embodiment is a cross bar, and there is a certain distance between the cross bar and the water tank in the horizontal direction.

[0045] In one embodiment, the first pressing assembly and the second pressing assembly are both provided with a pull rope 51, a fixed ring 52, a sliding ring 53, a pressing block 54 and a floating block 55 located in the water tank; the sliding ring 53 is fixedly set at the vertical top of the water tank, and the height of the sliding ring 53 and the bottom of the U-shaped fixing rod 5 to the ground is equal; the fixing ring 52 is sleeved on the bottom of the U-shaped fixing rod 5, one end of the pull rope 51 is fixedly connected to the fixing ring 52, and the other end of the pull rope 51 passes through the sliding ring 53 and is fixedly connected to the floating block 55; the pressing block 54 is fixedly connected to the middle of the pull rope 51.

[0046] In this embodiment, the pull rope 51 is a steel wire rope, and the diameter of the pull rope 51 is 5 mm to 7 mm.

[0047] Specifically, the fixed ring 52 can slide along the cross bar, and the height of the sliding ring 53 to the ground is equal to that of the bottom of the U-shaped fixed rod 5. In the initial state, the floating block 55 is not affected by the buoyancy of the accumulated water. Under the gravity of the floating block 55, the pull rope 51 between the fixed ring 52 and the sliding ring 53 is tightened and parallel to the horizontal plane; as the water in the water tank increases, the floating block 55 is affected by the buoyancy of the accumulated water, the floating block 55 rises, the pull rope 51 between the fixed ring 52 and the sliding ring 53 is tightened and loosened, and the pressing block 54 moves downward under the action of gravity; as the water in the water tank decreases, the floating block 55 descends, the pull rope 51 between the fixed ring 52 and the sliding ring 53 is gradually tightened, and the pressing block 54 moves upward.

[0048] It should be noted that in this embodiment, both the first and second pressing assemblies are equipped with a pull cord 51, a fixed ring 52, a sliding ring 53, a pressing block 54, and a floating block 55 located within the water tank. When initially installed, the two pressing blocks 54 must be positioned on top of the two buttons of the dual-button 1. Preferably, in the initial state, the fixed ring 52 and sliding ring 53 of the first pressing assembly and the fixed ring 52 and sliding ring 53 of the second pressing assembly are positioned at the four corners of the same horizontal rectangle. The two pressing blocks 54 are positioned on the two long sides, with their lengthwise width equal to the distance between the first button 11 and the second button 12.

[0049] In one embodiment, the pull cord 51 of the first pressing assembly is shorter than the pull cord 51 of the second pressing assembly; the height of the float 55 of the first pressing assembly within the water tank is greater than the height of the float 55 of the second pressing assembly within the water tank. The distance between the pressing block 54 of the first pressing assembly and the pressing block 54 of the second pressing assembly is equal to the distance between the first button 11 and the second button 12.

[0050] The height of the float 55 in the water tank is controlled by the length of the pull rope, thereby controlling the pressing order of the two buttons by the first pressing assembly and the second pressing assembly.

[0051] This embodiment of the automated pumping device for accumulated water in a mine sump uses a float 55 controlled by the sump water level to control the tension of a pull rope 51, thereby enabling the up and down movement of a pressing block 54, thereby pressing or releasing a double-button 1 and ultimately controlling the water pump via a QJZ-80 vacuum magnetic starter 2. This device fully automatically controls the start and stop of the water pump based on the accumulated water level, enabling timely drainage of the sump while reducing labor consumption.

[0052] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
