Description

Technical Field

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

[0002] In the mine operation environment, water accumulation in the tunnel is a problem that cannot be ignored. Its formation is usually due to a variety of factors. The infiltration of groundwater is one of the common reasons. The excavation of mine tunnels may destroy the underground hydrogeological structure, causing groundwater to flow into the tunnel along the rock cracks or loose strata. In addition, rainfall is also a factor that cannot be underestimated, especially in some shallow mines or areas where the wellhead is not tightly sealed. Rainwater may flow into the tunnel along the wellhead, ventilation ducts or rock cracks. And some water-using links in the mine production process, such as cooling of mining equipment, dust suppression spray, etc., will also cause water to accumulate in the tunnel if the drainage system is not perfect.

[0003] Water accumulation in tunnels can cause many serious hazards to mine production. First, a large amount of water accumulation will flood the working area, directly hinder normal mining work, and cause production stagnation. Secondly, the water accumulation will soak the tunnel wall and floor, weaken the stability of the rock formation, and increase the risk of accidents such as roof collapse and spalling. Furthermore, the contact between the accumulated water and the metal equipment and rails in the tunnel will accelerate the corrosion and rust of the metal, shorten the service life of the equipment, and increase the maintenance cost and replacement frequency of the equipment. Moreover, the accumulated water may also mix with the coal dust, rock dust, etc. in the tunnel to form mud, deteriorate the working environment, affect the miners' vision and respiratory health, and also bring additional burden to the ventilation system, affecting the underground air quality and wind flow stability. The accumulated water in the tunnel will first enter the water tank dug at the bottom of the tunnel, and enter the tunnel after the water tank is full. Therefore, it is very important to discharge the accumulated water in the water tank in time.

[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 the present invention, “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 operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In one embodiment, Figure 1 As shown, Figure 1It is one of the structural schematic diagrams of the automatic pumping device for mine tunnel water tank provided in an embodiment of the present invention. The automatic pumping device for mine tunnel water tank in this embodiment includes a drainage component and a control component for controlling the working condition of the drainage component according to the water level in 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 arranged between the drain pipe 6 and the water pump 4 to prevent the water in the drain pipe 6 from flowing back to the water pump 4. The ultimate purpose of the check valve is to prevent the water remaining 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 provided 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 casing 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 which can press the two buttons of the two-button 1 respectively according to the water level of the water tank, and a QJZ-80 vacuum magnetic starter 2 which 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 being pressed, and a second button 12 that can connect the second interface and the third interface after being pressed.

[0037] The button pressing conditions of the two-link 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 5 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 for starting, and 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, and the resettable buttons 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 pressing water level of the first pressing component is high, when the water level in the water tank rises, the second pressing component first presses the second button 12, and then as the water level continues to rise, the first pressing component presses the first button 11. When the water level gradually decreases after drainage, the first button 11 is reset first, and then the second button 12 is reset.

[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, and then automatically start or stop 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 of the embodiments, 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 arranged at the vertical top of the water tank, and the height from the sliding ring 53 to the ground is equal to that of the bottom of the U-shaped fixing rod 5; 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 is fixedly connected to the floating block 55 after passing through the sliding ring 53; 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 from the bottom of the sliding ring 53 to the ground is equal to that 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 the first pressing assembly and the second pressing assembly in this embodiment 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. When installed to the initial state, it is necessary to ensure that the two pressing blocks 54 are respectively located on the top of the two buttons of the two-linked button 1. Preferably, when the first pressing assembly and the second pressing assembly are in the initial state, the fixed ring 52 and the sliding ring 53 of the first pressing assembly and the fixed ring 52 and the sliding ring 53 of the second pressing assembly are respectively located at the four corners of the same horizontal rectangle. The two pressing blocks 54 are respectively located on the two long sides, and the width in the long direction is equal to the distance between the first button 11 and the second button 12.

[0049] In one embodiment, the length of the pull rope 51 of the first pressing assembly is shorter than the length of the pull rope 51 of the second pressing assembly; the height of the floating block 55 of the first pressing assembly in the water tank is greater than the height of the floating block 55 of the second pressing assembly in 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 realizing the control of the pressing sequence of the two buttons by the first pressing assembly and the second pressing assembly.

[0051] The automatic pumping device for water accumulation in a mine water tank of this embodiment can control the tightness of the pull rope 51 based on the floating block 55 controlled by the water level of the water tank, thereby realizing the up and down movement of the pressing block 54, realizing the pressing or releasing of the two-link button 1, and finally realizing the control of the water pump by the QJZ-80 vacuum magnetic starter 2. The device can fully automatically control the start or stop of the water pump according to the water accumulation in the water tank, can drain the water tank in time and can reduce manpower consumption.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
