Description

Technical Field

[0001] This invention relates to the field of underground mine water tank dredging technology, specifically to an automatic dredging system for underground mine water tanks. Background Technology

[0002] During mining operations, underground water carrying large amounts of silt, ore fragments, coal dust, and other solid particles flows into the water tank. Over time, if this silt is not cleaned in a timely manner, it will accumulate at the bottom of the water tank. For example, in a water tank designed for a volume of 1,000 cubic meters, if silt is not removed for a long period, hundreds of cubic meters of space may be occupied by silt, significantly reducing the effective water storage capacity of the water tank. When the effective volume of the water tank decreases, its ability to buffer mine water inflow also decreases. In the event of a sudden increase in mine water inflow (such as during heavy rain causing a large influx of surface water into the mine), the water tank may be unable to hold the excess water, leading to a mine flood and threatening safe production.

[0003] An automatic sludge removal system can promptly remove sludge from water tanks, ensuring that the tanks always maintain sufficient volume to store mine water. To facilitate sludge removal at different locations within the water tank, the automatic sludge removal system incorporates a mobile tracked sludge removal robot. This robot moves within the mine's underground water tank and collects the sludge. However, during the sludge collection process, due to the liquid state of the sludge and the uneven surface of the water tank, the collected sludge experiences strong shaking within the robot, affecting its stability during sludge collection and movement. Therefore, we propose an automatic sludge removal system for underground mine water tanks. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1-7 The automatic sludge removal system for the underground water tank in the mine, as shown in the diagram, includes:

[0031] Tracked sludge removal robot is used to walk inside underground water tanks in mines and suck up and collect sludge;

[0032] A sand-water separator is used to separate the collected sludge from the sludge and water, and from the sand and gravel.

[0033] The cleaning pump is used to guide the separated sludge upwards to the ground of the underground water tank in the mine. The inlet of the cleaning pump is connected to the sludge-water mixture separated on the sand-water separator through a steel wire hose.

[0034] It should be noted that during the operation of the automatic sludge removal system for underground mine water tanks, a tracked sludge removal robot is placed inside the mine water tank. After placement, the tracked sludge removal robot moves inside the mine water tank and sucks up and collects sludge. The collected sludge is then transported to the sand-water separator, where the sludge-water mixture is separated from the sand and gravel. After separation, the sludge-water mixture is raised to the surface of the water tank by the driving action of a cleaning pump and the connection of a steel wire hose, completing the sludge removal operation inside the mine water tank.

[0035] Preferably, the tracked dredging robot includes a tracked chassis 101, a mounting base 102 is fixed to the upper end of the tracked chassis 101, a collection cylinder 103 is fixed on the mounting base 102, a buoyancy pressure plate 2 is provided inside the collection cylinder 103 for squeezing the collected sludge and water, the buoyancy pressure plate 2 is matched with the interior of the collection cylinder 103, a squeezing component is provided on the mounting base 102 for squeezing and pushing the buoyancy pressure plate 2, and a feeding component for assisting feeding and a discharging component for assisting discharging are provided between the buoyancy pressure plate 2 and the collection cylinder 103.

[0036] It should be noted that during the process of the tracked sludge dredging robot moving inside the underground water tank of the mine and sucking up and collecting sludge, the cooperation of components such as the feeding component and the extrusion component can not only collect sludge from different locations, but also exert extrusion pressure on the sludge collected inside the collection cylinder 103 after collection. This prevents the collected sludge from shaking violently due to the bumpy movement of the tracked sludge dredging robot, ensuring the stability of the sludge dredging robot in sludge collection and movement, and further ensuring the sludge dredging effect.

[0037] Preferably, two sets of extrusion assemblies are provided between the buoyancy pressure plate 2 and the mounting base 102, and the two sets of extrusion assemblies are arranged symmetrically to each other;

[0038] It should be noted here that the extrusion effect is ensured by using two sets of extrusion components.

[0039] Preferably, the extrusion assembly includes an L-shaped frame 901 fixed to the buoyancy plate 2, a T-shaped rod 902 slidably connected to the L-shaped frame 901, one end of the T-shaped rod 902 being fixed to the upper end of the mounting base 102, and a first spring 903 being sleeved on the outer side of the T-shaped rod 902, one end of the first spring 903 abutting against the upper end of the L-shaped frame 901, and the other end of the first spring 903 abutting against the T-shaped end of the T-shaped rod 902;

[0040] It should be noted that during the collection of sludge inside the collection cylinder 103, as the sludge flows into the collection cylinder 103 and is pushed against the buoyancy plate 2, the buoyancy plate 2 moves upward inside the collection cylinder 103 in sync with the collection of sludge. During the upward movement of the buoyancy plate 2, it pushes the L-shaped frame 901 to slide on the T-shaped rod 902 and causes the first spring 903 to deform under force and generate elastic force. Through the squeezing and pushing action of the first spring 903 on the L-shaped frame 901 and the buoyancy plate 2, a squeezing force is generated on the sludge collected inside the collection cylinder 103.

[0041] Preferably, the feeding assembly includes a first mounting frame 301 fixed to the outside of the collection cylinder 103, a pump 302 mounted on the first mounting frame 301, a first conveying hose 303 mounted on the discharge end of the pump 302, one end of the first conveying hose 303 being connected to the lower part of the buoyancy pressure plate 2, an installation pipe 304 provided on the mounting base 102, the installation pipe 304 being connected to the feed end of the pump 302 through a first bellows pipe 305, a moving component for moving the installation pipe 304 and a guiding component for guiding the movement, and a protective component for protecting the feed at the front end of the installation pipe 304.

[0042] It should be noted that during the process of the tracked sludge dredging robot moving inside the underground water tank of the mine and sucking up and collecting sludge, the feed head 401 at the front end of the tracked sludge dredging robot is inserted into the sludge. After the feed head 401 is inserted, through the driving action of the pump 302 and the connection action of the first conveying hose 303, the installation pipe 304 and the first bellows pipe 305, the sludge enters from the various sets of through slots 403 on the annular groove 402 into the interior of the feed head 401 and is then conveyed to the interior of the collection cylinder 103 for collection.

[0043] Preferably, the protective component includes a feed head 401 disposed at the front end of the mounting tube 304. The feed head 401 and the mounting tube 304 are connected through a second bellows tube 405. A telescopic component for assisting the telescopic connection of the feed head 401 is disposed between the mounting tube 304 and the feed head 401. An annular groove 402 is provided on the outer side of the feed head 401. Multiple sets of through grooves 403 are provided between the annular groove 402 and the interior of the feed head 401. The through grooves 403 are arranged in a ring array. Multiple sets of blocking rods 404 for blocking foreign objects are fixed inside the annular groove 402. The blocking rods 404 are arranged in a ring array. A conical surface 5 is provided at the front end of the feed head 401 to facilitate the transmission of the material against foreign objects.

[0044] It should be noted that during the process of the feed head 401 moving to different positions in the lateral direction to collect sludge, when the conical surface 5 on the feed head 401 comes into contact with foreign objects at the sludge collection position, the feed head 401 is pushed by the contact between the conical surface 5 and the foreign objects, causing it to retract towards the mounting pipe 304. This retraction movement of the feed head 401 facilitates automatic retraction after encountering obstacles during the mobile sludge collection process, reducing the probability of the feed head 401 being damaged by collisions during sludge collection and ensuring stable sludge collection operation.

[0045] Preferably, the telescopic assembly includes an annular plate 604 sleeved and fixed to the outside of the mounting tube 304, multiple sets of sleeves 601 fixed to the end of the feed head 401, a sliding rod 602 slidably connected to the sleeve 601, one end of the sliding rod 602 being fixed to the annular plate 604, and a second spring 603 sleeved on the outside of the sleeve 601, with both ends of the second spring 603 being connected to the end of the feed head 401 and the annular plate 604 respectively.

[0046] It should be noted that the sleeve 601 and the slide rod 602 facilitate the telescopic connection between the feed head 401 and the mounting tube 304, and the second spring 603 facilitates the reset movement of the feed head 401 after its retraction movement.

[0047] Preferably, the movable component includes a mounting sleeve 701 that is sleeved and fixed to the outside of the mounting tube 304, a fixing plate 702 fixed on the mounting sleeve 701, a threaded sleeve 703 fixed on the fixing plate 702, two sets of fixing brackets 704 fixed to the upper end of the mounting base 102, a lead screw 705 rotatably connected between the two sets of fixing brackets 704, the lead screw 705 and the threaded sleeve 703 being mutually engaged, and a drive motor 706 for driving the rotation of the lead screw 705 is mounted on the fixing brackets 704; the guide component includes multiple sets of guide holes 801 opened on the fixing plate 702, a guide rod 802 slidably connected to each set of guide holes 801, and the guide rod 802 fixed between the two sets of fixing brackets 704;

[0048] It should be noted that: the drive motor 706 drives the lead screw 705 to rotate. During the rotation of the lead screw 705, the mutual meshing transmission between the lead screw 705 and the threaded sleeve 703 on the fixed plate 702 drives the fixed plate 702 and the mounting sleeve 701 to move under force. During the movement of the fixed plate 702 and the mounting sleeve 701 under force, the sliding guidance effect of each set of guide holes 801 and each set of guide rods 802 causes the fixed plate 702 and the mounting sleeve 701 to reciprocate between the two sets of fixed frames 704. The movement of the mounting sleeve 701 drives the mounting tube 304 and the feed head 401 to move synchronously. The movement of the feed head 401 facilitates the tracked dredging robot to perform dredging and collection processing at different positions in the lateral direction while moving.

[0049] Preferably, the discharge assembly includes a second mounting bracket 1001 fixed to the outside of the collection cylinder 103, a conveying pump 1002 is mounted on the second mounting bracket 1001, a second conveying hose 1003 is mounted on the inlet end of the conveying pump 1002, and one end of the second conveying hose 1003 is connected to the lower part of the buoyancy pressure plate 2.

[0050] It should be noted that the driving action of the conveying pump 1002 and the connecting action of the second conveying hose 1003 facilitate the discharge and conveying operation of the sludge collected inside the collection cylinder 103.

[0051] In this plan, the automatic sludge removal system for underground water tanks in mines includes the following steps:

[0052] During operation, the automatic sludge removal system for underground mine water tanks involves placing a tracked sludge removal robot inside the water tank. Once placed, the robot moves within the tank and collects sludge. The collected sludge is then transported to a sand-water separator, where it separates the sludge and water from the sand and gravel. After separation, the sludge and water are raised to the surface of the water tank via a pump and a connecting steel hose, completing the sludge removal operation inside the underground mine water tank.

[0053] As the tracked sludge dredging robot moves inside the underground water tank of the mine and collects sludge, the feed head 401 at the front of the tracked sludge dredging robot is inserted into the sludge. After the feed head 401 is inserted, driven by the pump 302 and connected by the first conveying hose 303, the installation pipe 304, and the first bellows pipe 305, the sludge enters from the various through slots 403 on the annular groove 402 into the feed head 401 and is then conveyed to the collection cylinder 103 for collection. During the collection process inside the collection cylinder 103, as the sludge flows into the collection cylinder 103 and interacts with the buoyancy plate 2... The opposing pushing action causes the buoyancy plate 2 to move upwards inside the collection cylinder 103 in sync with the collection of sludge. During the upward movement of the buoyancy plate 2, it pushes the L-shaped frame 901 to slide on the T-shaped rod 902 and causes the first spring 903 to deform under force and generate elastic force. Through the squeezing and pushing action of the first spring 903 on the L-shaped frame 901 and the buoyancy plate 2, it generates squeezing force on the sludge collected inside the collection cylinder 103, preventing the collected sludge from shaking violently due to the bumpy walking of the tracked sludge dredging robot, ensuring the stability of the tracked sludge dredging robot in sludge collection and movement, and further ensuring the sludge dredging effect.

[0054] Furthermore, during the dredging and collection process, the tracked dredging robot drives the lead screw 705 to rotate via the drive motor 706. During the rotation of the lead screw 705, the engagement between the lead screw 705 and the threaded sleeve 703 on the fixed plate 702 drives the fixed plate 702 and the mounting sleeve 701 to move under force. During this movement, the fixed plate 702 and the mounting sleeve 701 are guided by the sliding action of the guide holes 801 and the guide rods 802, causing the fixed plate 702 and the mounting sleeve 701 to reciprocate between the two sets of fixed frames 704. The movement of the mounting sleeve 701 then drives the mounting pipe 304 and the feed head 401 to move synchronously. The movement of the feed head 401 facilitates the dredging robot to collect sludge from different locations laterally while moving. During the dredging process, when the conical surface 5 on the feed head 401 comes into contact with foreign objects at the dredging location, the force exerted by the contact between the conical surface 5 and the foreign objects causes the feed head 401 to retract towards the mounting tube 304. This retraction movement of the feed head 401 facilitates automatic retraction after encountering obstacles during the mobile dredging process, reducing the probability of damage from obstacle collisions and ensuring stable dredging operations.
