Description

Technical Field

[0001] This utility model relates to the field of groundwater drainage technology, and in particular to an emergency groundwater drainage device for mining. Background Technology

[0002] Groundwater drainage systems are equipment used to remove groundwater and ensure operational safety. They mainly include drainage pumps and related facilities. Due to the complex geological conditions in mines, seepage and water accumulation are very likely to occur. Therefore, groundwater drainage systems are an essential component of mine operation.

[0003] During mining operations, large amounts of gravel and sand are typically generated. This debris falls into the water and mixes with it. When groundwater drainage systems pump out water, this debris and sediment are often drawn into the systems along with the water, easily causing blockages and disrupting their normal operation. Therefore, effectively preventing these blockages is a crucial issue that needs to be addressed in the design of emergency groundwater drainage systems for mines. Utility Model Content

[0004] This utility model provides an emergency groundwater drainage device for mines to solve the problem that gravel and silt can easily clog groundwater drainage devices.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides an emergency drainage device for groundwater in mines, including a mine pump, and further comprising: a drain pipe fixedly installed on the top of the mine pump, and the mine pump being connected to a filter housing through an inlet pipe;

[0007] A filter structure, wherein the filter structure is disposed inside the filter housing;

[0008] A blocking structure is disposed on both sides of the filter structure;

[0009] A limiting structure is provided on the sealing structure, and the limiting structure restricts the rotation of the sealing structure.

[0010] Preferably, a water pumping pipe is fixedly installed on the top side wall of the filter housing, and a first shielding door and a second shielding door are rotatably connected to the side wall of the filter housing.

[0011] In this technical solution, water is pumped out through a water pipe, and the debris and mud can be cleared by opening the first and second shielding doors.

[0012] Preferably, the filter structure includes a first filter screen, a second filter screen, a first baffle, and a second baffle. The first baffle and the second baffle are both fixedly connected to the bottom inner sidewall of the filter housing. One sidewall of the first filter screen is fixedly connected to the inner sidewall of the filter housing, and the other sidewall of the first filter screen is fixedly connected to the top of the sidewall of the second baffle. One sidewall of the second filter screen is fixedly connected to the sidewall of the first baffle, and the other sidewall of the second filter screen is fixedly connected to the top of the sidewall of the second baffle.

[0013] In this technical solution, filter screen one and filter screen two filter larger stones and silt mixed in the water. The filtered stones and silt fall into the cavities on both sides of baffle one and baffle two under the flushing of the water flow and are collected. As the water flowing into the cavities of stones and silt gradually accumulates, when the water level in the cavities is higher than that of baffle one and baffle two, it will overflow from baffle one and baffle two and fall into the middle cavity for discharge.

[0014] Preferably, both filter screen one and filter screen two are inclined.

[0015] Preferably, the first filter screen and the second filter screen are tilted in opposite directions.

[0016] In this technical solution, the filtered gravel and silt roll down under the scouring of the water flow.

[0017] Preferably, the filter structure includes a first baffle, a second baffle, a third baffle, and a fourth baffle. The first baffle and the third baffle are fixedly connected to the side walls of the first baffle and the second baffle, respectively. The second baffle and the fourth baffle are fixedly connected to the side walls of both sides of the filter housing. The top side walls of the first baffle, the second baffle, the third baffle, and the fourth baffle are all inclined. The bottom side walls of the first baffle and the second baffle are at the same height as each other. The bottom side walls of the third baffle and the fourth baffle are at the same height as each other.

[0018] Preferably, the sealing structure includes a sealing plate, a rotating block, a sliding groove, and a threaded rod. Two sealing plates are rotatably connected to the inner wall of the filter housing. The sealing plates are located on the left side of the first baffle and the right side of the second baffle, respectively. The rotating shaft at one end of the sealing plate extends out of the side wall of the filter housing and is fixedly connected to the rotating block. A sliding groove is provided on the side wall of the rotating block, and a threaded rod is fixedly connected to the inner wall of the sliding groove.

[0019] In this technical solution, rotating the rotating block causes the baffle plate to rotate, so that the baffle plate is tightly attached to the bottom side wall of baffle one, baffle two or baffle three and baffle four, sealing the top of baffle one and baffle two, and preventing the continuous flow of gravel, mud and water from above during cleaning.

[0020] Preferably, the limiting structure includes a limiting block, a snap-fit ​​groove, a threaded sleeve, a snap-fit ​​rod, and a connecting ring. An arc-shaped limiting block is fixedly connected to the inner side wall of the filter housing. Two snap-fit ​​grooves are formed on the side wall of the limiting block. The threaded sleeve is threadedly connected to the threaded rod. A connecting ring is rotatably connected to the side wall of the threaded sleeve. A snap-fit ​​rod is fixedly connected to the side wall of the connecting ring.

[0021] In this technical solution, the movement of the threaded sleeve drives the movement of the connecting ring, which in turn drives the movement of the locking rod, causing the locking rod to engage with the corresponding locking groove, thereby restricting the rotation of the rotating block.

[0022] Preferably, the two snap-fit ​​slots are perpendicular to each other.

[0023] In this technical solution, the locking groove can better cooperate with the rotation of the locking rod.

[0024] Preferably, the locking rod and the locking groove cooperate with each other.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] 1. Larger stones and silt mixed in the water are filtered through filter screen one and filter screen two. The filtered stones and silt fall into the cavities on both sides of baffle one and baffle two under the flushing of the water flow, which facilitates better filtration and collection of stones and silt in the water and avoids clogging of the mine pump by stones and silt.

[0028] 2. By rotating the threaded sleeve, the locking rod is disengaged from the locking groove. Rotating the rotating block causes the baffle plate to rotate, making the baffle plate tightly adhere to the bottom side wall of baffle one, baffle two, or baffle three and baffle four, sealing the top of baffle one and baffle two. Then, opening baffle door one and baffle door two allows for the cleaning of gravel and mud. This facilitates the cleaning of collected gravel and mud while preventing the continuous flow of gravel, mud, and water from above during cleaning. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figure 1-5 As shown, the emergency drainage device for groundwater in mines includes a mine pump 1, and further includes: a drain pipe 2 fixedly installed on the top of the mine pump 1, and the mine pump 1 is connected to a filter housing 4 through a water inlet pipe 3.

[0038] Filter structure 8, which is disposed inside filter housing 4;

[0039] A blocking structure 9 is provided on both sides of the filter structure 8;

[0040] A limiting structure 10 is provided on the sealing structure 9, and the limiting structure 10 restricts the rotation of the sealing structure 9.

[0041] A water pumping pipe 5 is fixedly installed on the top side wall of the filter housing 4, and a shielding door 6 and a shielding door 7 are rotatably connected to the side wall of the filter housing 4.

[0042] Water is pumped out through the water pipe 5, and the debris and mud can be cleared by opening the first shield door 6 and the second shield door 7.

[0043] The filter structure 8 includes a first filter screen 801, a second filter screen 802, a first baffle 803, and a second baffle 804. The first baffle 803 and the second baffle 804 are both fixedly connected to the bottom inner sidewall of the filter housing 4. One sidewall of the first filter screen 801 is fixedly connected to the inner sidewall of the filter housing 4, and the other sidewall of the first filter screen 801 is fixedly connected to the top of the sidewall of the first baffle 803. One sidewall of the second filter screen 802 is fixedly connected to the sidewall of the first baffle 803, and the other sidewall of the second filter screen 802 is fixedly connected to the top of the sidewall of the second baffle 804.

[0044] Filter screen 1 801 and filter screen 2 802 filter larger stones and silt mixed in the water. The filtered stones and silt are washed down by the water flow and collected in the cavities on both sides of baffle 1 803 and baffle 2 804. As the stones and silt flow into the cavities, the water gradually accumulates. When the water level in the cavities is higher than baffle 1 803 and baffle 2 804, it overflows through baffle 1 803 and baffle 2 804 and falls into the middle cavity for discharge.

[0045] Both filter screen 801 and filter screen 802 are inclined.

[0046] The first filter screen 801 and the second filter screen 802 are tilted in opposite directions.

[0047] The filtered gravel and silt roll down the water flow.

[0048] The filter structure 8 includes a first block 811, a second block 812, a third block 813, and a fourth block 814. The first block 811 and the third block 813 are fixedly connected to the side walls of the first baffle 803 and the second baffle 804, respectively. The second block 812 and the fourth block 814 are fixedly connected to the side walls on both sides of the filter housing 4, respectively. The top side walls of the first block 811, the second block 812, the third block 813, and the fourth block 814 are all inclined. The bottom side walls of the first block 811 and the second block 812 are at the same height as each other. The bottom side walls of the third block 813 and the fourth block 814 are at the same height as each other.

[0049] The sealing structure 9 includes a sealing plate 901, a rotating block 902, a sliding groove 903, and a threaded rod 904. Two sealing plates 901 are rotatably connected to the inner wall of the filter housing 4. The sealing plates 901 are located on the left side of the first baffle 803 and the right side of the second baffle 804, respectively. The rotating shaft at one end of the sealing plate 901 extends out of the side wall of the filter housing 4 and is fixedly connected to the rotating block 902. A sliding groove 903 is provided on the side wall of the rotating block 902, and a threaded rod 904 is fixedly connected to the inner wall of the sliding groove 903.

[0050] Rotate the rotating block 902, which will cause the baffle to rotate 90 degrees, so that the baffle is tightly attached to the bottom side wall of baffle 1 803, baffle 2 812 or baffle 3 813 and baffle 4 814, sealing the top of baffle 1 803 and baffle 2 804, and preventing the continuous flow of gravel, mud and water from above during cleaning.

[0051] The limiting structure 10 includes a limiting block 1001, a snap-fit ​​groove 1002, a threaded sleeve 1003, a snap-fit ​​rod 1004, and a connecting ring 1005. An arc-shaped limiting block 1001 is fixedly connected to the inner side wall of the filter housing 4. Two snap-fit ​​grooves 1002 are opened on the side wall of the limiting block 1001. The threaded sleeve 1003 is threadedly connected to the threaded rod 904. The connecting ring 1005 is rotatably connected to the side wall of the threaded sleeve 1003. The snap-fit ​​rod 1004 is fixedly connected to the side wall of the connecting ring 1005.

[0052] The movement of the threaded sleeve 1003 causes the connecting ring 1005 to move, and the connecting ring 1005 causes the locking rod 1004 to move, so that the locking rod 1004 engages with the corresponding locking groove 1002, thereby restricting the rotation of the rotating block 902.

[0053] The two slots 1002 are perpendicular to each other.

[0054] This allows the locking slot 1002 to better cooperate with the rotation of the locking rod 1004.

[0055] The locking rod 1004 and the locking groove 1002 cooperate with each other.

[0056] In use, all electrical components mentioned in this application are connected to an external power supply and control switch. When the water pumping pipe 5 is placed in the water, the mine water pump 1 works to pump water. The water enters the filter housing 4 through the water pumping pipe 5. Rotating the threaded sleeve 1003 causes the threaded sleeve 1003 to rotate and move on the threaded rod 904. The movement of the threaded sleeve 1003 drives the connecting ring 1005 to move. The connecting ring 1005 drives the snap-fit ​​rod 1004 to move, so that the snap-fit ​​rod 1004 disengages from the corresponding snap-fit ​​groove 1002 and no longer restricts the rotation of the rotating block 902.

[0057] Rotating the rotating block 902 causes the sealing plate 901 to rotate downwards by 90 degrees, so that the sealing plate 901 fits against the side walls of the first baffle 803 and the second baffle 804, no longer blocking the top of the first baffle 803 and the second baffle 804. The filter screens 801 and 802 filter out larger stones and silt mixed in the water. The filtered stones and silt fall into the cavities on both sides of the first baffle 803 and the second baffle 804 under the flushing of the water flow and are collected. As the water flows into the cavities, the stones and silt gradually accumulate. When the water level in the cavities is higher than the first baffle 803 and the second baffle 804, it will overflow from the first baffle 803 and the second baffle 804 and fall into the middle cavity for discharge.

[0058] When it is necessary to clean the gravel and mud in the cavities on both sides of baffle 1 803 and baffle 2 804, rotate the threaded sleeve 1003 so that the locking rod 1004 disengages from the locking groove 1002 again. Rotate the rotating block 902 in the opposite direction. The rotating block 902 drives the baffle to rotate 90 degrees, so that the baffle is tightly attached to the bottom side wall of baffle 1 803, baffle 2 812 or baffle 3 813 and baffle 4 814, sealing the top of baffle 1 803 and baffle 2 804. Then open the baffle door 1 6 and baffle door 2 7 to clean the gravel and mud.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
