Description

Technical Field

[0001] The invention relates to the technical field of desilting underground water tanks in mines, in particular to an automatic desilting system for underground water tanks in mines. Background Art

[0002] During the mining process, underground water will flow into the water tank mixed with a large amount of solid particulate matter such as silt, ore debris, and coal dust. Over time, if these silts are not cleaned in time, they will continue to accumulate at the bottom of the water tank. For example, if a water tank with a designed volume of 1,000 cubic meters is not cleared for a long time, hundreds of cubic meters of space may be occupied by silt, which greatly reduces the effective water storage capacity of the water tank. When the effective volume of the water tank decreases, its ability to buffer the mine water inrush will also decrease. In the case of a sudden increase in the amount of water inrush in the mine (such as heavy rain weather causing a large amount of surface water to flow into the mine), the water tank may not be able to accommodate the excess water, which will cause mine flooding and threaten the safe production of the mine.

[0003] The automatic dredging system can remove the silt in the water tank in time to ensure that the water tank always maintains a sufficient volume to store mine water. In order to facilitate dredging at different locations in the water tank, a movable tracked dredging robot is set on the automatic dredging system to walk inside the underground water tank of the mine and suck and collect the silt. In the process of the crawler dredging robot sucking and collecting the silt, the silt is in liquid state and the ground in the water tank is uneven. When the crawler dredging robot walks inside the underground water tank of the mine and sucks and collects the silt, the collected silt will shake violently inside the crawler dredging robot as the robot moves, affecting the stability of the crawler dredging robot's dredging, collection and moving. For this reason, we propose an automatic dredging system for underground water tanks in mines. Summary of the invention

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

[0029] Example 1

[0030] See also Figure 1-Figure 7 The automatic desilting system for underground water tanks in the mine shown in the figure includes:

[0031] Tracked silt removal robot, used to walk inside the underground water tank of the mine and suck and collect silt;

[0032] The sand-water separator is used to separate the collected silt into water and sand and gravel;

[0034] It should be noted here that during the operation of the automatic dredging system for underground mine water tanks, a crawler dredging robot is placed inside the underground mine water tank. After the placement is completed, the crawler dredging robot walks inside the underground mine water tank and sucks in and collects the silt. The collected silt is transported to the inside of the sand-water separator, and the silt water and sand and gravel are separated by the sand-water separator. After separation, the silt water is raised to the surface of the water tank through the driving action of the sewage pump and the connection action of the steel wire hose, thereby completing the dredging operation inside the underground mine water tank.

[0035] Preferably, the crawler dredging robot comprises a crawler chassis 101, a mounting seat 102 is fixed to the upper end of the crawler chassis 101, a collecting barrel 103 is fixed to the mounting seat 102, a buoyancy pressure plate 2 for squeezing the collected sludge water is arranged inside the collecting barrel 103, the buoyancy pressure plate 2 and the interior of the collecting barrel 103 are matched with each other, an extrusion component for squeezing and pushing the buoyancy pressure plate 2 is arranged on the mounting seat 102, and a feeding component for auxiliary feeding and a discharging component for auxiliary discharging are arranged between the buoyancy pressure plate 2 and the collecting barrel 103;

[0036] It should be noted here that: when the tracked dredging robot walks inside the underground water tank of the mine and sucks in and collects silt, the feeding assembly, the extrusion assembly and other components cooperate with each other, so that it can not only collect silt at different positions, but also generate extrusion pressure on the silt collected inside the collection tube 103 after collection, so as to avoid the strong shaking of the collected silt due to the bumpy walking of the tracked dredging robot, thereby ensuring the stability of the tracked dredging robot in silt collection and mobile driving, and further ensuring the dredging effect.

[0037] Preferably, two groups of extrusion components are provided between the buoyancy pressure plate 2 and the mounting seat 102, and the two groups of extrusion components are provided in a mutually symmetrical state;

[0040] It should be noted here that: during the process of collecting the sucked sludge inside the collecting barrel 103, as the sludge flows into the collecting barrel 103 and the sludge and the buoyancy pressure plate 2 push each other, the buoyancy pressure plate 2 moves upward inside the collecting barrel 103 synchronously with the collection of the sludge inside the collecting barrel 103. During the upward movement of the buoyancy pressure plate 2, the L-shaped frame 901 is pushed to slide on the T-shaped rod 902, and the first spring 903 is deformed by force to generate elastic force. Through the squeezing and pushing action of the first spring 903 on the L-shaped frame 901 and the buoyancy pressure plate 2, an extrusion force is generated on the sludge collected inside the collecting barrel 103.

[0041] Preferably, the feed assembly includes a first mounting frame 301 fixed to the outside of the collecting barrel 103, a feed pump 302 is mounted on the first mounting frame 301, a first conveying hose 303 is mounted at the discharge end of the feed pump 302, one end of the first conveying hose 303 is connected to the bottom of the buoyancy pressure plate 2, a mounting pipe 304 is arranged on the mounting seat 102, the mounting pipe 304 is connected to the feed end of the feed pump 302 through a first accordion pipe 305, a moving assembly for moving the mounting pipe 304 and a guiding assembly for guiding during the movement are arranged on the mounting seat 102, and a protective assembly for feeding protection is arranged at the front end of the mounting pipe 304;

[0042] It should be noted here that: when the tracked dredging robot walks inside the underground water tank of the mine and sucks in and collects the sludge, the feed head 401 at the front end of the tracked dredging robot is inserted into the interior of the sludge. After the feed head 401 is inserted, through the driving action of the suction pump 302 and the connection action of the first conveying hose 303, the mounting pipe 304 and the first organ pipe 305, the sludge enters the interior of the feed head 401 from the various groups of through grooves 403 on the annular groove 402 and is transported and falls into the interior of the collecting cylinder 103 for collection.

[0043] Preferably, the protection component includes a feed head 401 arranged at the front end of the mounting tube 304, the feed head 401 and the mounting tube 304 are connected by a second accordion pipe 405, a telescopic component for assisting the feed head 401 to be telescopically connected is arranged between the mounting tube 304 and the feed head 401, an annular groove 402 is provided on the outside of the feed head 401, a plurality of groups of through grooves 403 are provided between the annular groove 402 and the inside of the feed head 401, each group of through grooves 403 is arranged in a state of an annular array, a plurality of groups of blocking rods 404 for blocking foreign matter in the feed are fixed inside the annular groove 402, each group of blocking rods 404 is arranged in a state of an annular array, and a conical surface 5 is provided at the front end of the feed head 401 for assisting the transmission against foreign matter;

[0044] It should be noted here that: in the process of the feed head 401 moving to perform dredging and collection at different positions in the horizontal direction, when the conical surface 5 on the feed head 401 abuts against the foreign matter at the dredging position, the feed head 401 is forced to retract toward the mounting tube 304 through the pushing effect of the conical surface 5 and the foreign matter. The retraction movement of the feed head 401 facilitates the automatic retraction of the feed head 401 when encountering an obstacle during the mobile dredging and collection process, thereby reducing the probability of the feed head 401 being damaged by encountering an obstacle during the dredging and collection process, and facilitating stable dredging and collection operations.

[0045] Preferably, the telescopic assembly includes an annular plate 604 sleeved and fixed on the outside of the mounting tube 304, a plurality of sleeves 601 are fixed to the end of the feed head 401, a slide rod 602 is slidably connected to the sleeve 601, one end of the slide rod 602 is fixed to the annular plate 604, a second spring 603 is sleeved on the outside of the sleeve 601, and both ends of the second spring 603 are respectively connected to the end of the feed head 401 and the annular plate 604;

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

[0047] Preferably, the moving assembly includes a mounting sleeve 701 sleeved and fixed on the outside of the mounting tube 304, a fixing plate 702 is fixed on the mounting sleeve 701, a threaded sleeve 703 is fixed on the fixing plate 702, two sets of fixing frames 704 are fixed on the upper end of the mounting seat 102, a screw rod 705 is rotatably connected between the two sets of fixing frames 704, the screw rod 705 and the threaded sleeve 703 are meshed with each other, and a driving motor 706 for rotating the screw rod 705 is installed on the fixing frame 704; the guide assembly includes a plurality of guide holes 801 provided on the fixing plate 702, each set of guide holes 801 is slidably connected to a guide rod 802, and the guide rod 802 is fixed between the two sets of fixing frames 704;

[0048] It should be noted here that: the screw rod 705 is driven to rotate by the driving motor 706. During the rotation of the screw rod 705, the screw rod 705 and the threaded sleeve 703 on the fixed plate 702 are mutually engaged and driven to drive the fixed plate 702 and the mounting sleeve 701 to move under force. During the force movement of the fixed plate 702 and the mounting sleeve 701, the fixed plate 702 and the mounting sleeve 701 are reciprocated between the two groups of fixed frames 704 through the sliding guiding effect of each group of guide holes 801 and each group of guide rods 802. The movement of the mounting sleeve 701 drives the mounting pipe 304 and the feed head 401 to move synchronously. The movement of the feed head 401 facilitates the crawler dredging robot to perform dredging, collection and processing of different positions in the horizontal direction while moving.

[0049] Preferably, the discharge assembly includes a second mounting frame 1001 fixed to the outside of the collecting barrel 103, a delivery pump 1002 is installed on the second mounting frame 1001, a second delivery hose 1003 is installed at the feed end of the delivery pump 1002, and one end of the second delivery hose 1003 is connected to the bottom of the buoyancy pressure plate 2;

[0050] It should be noted here that the sludge collected in the collecting barrel 103 can be easily discharged and transported by the driving action of the delivery pump 1002 and the connecting action of the second delivery hose 1003 .

[0051] In this scheme: the automatic silt removal system for underground water tanks in mines includes the following steps:

[0052] During the operation of the automatic silt removal system for underground mine silos, a crawler silt removal robot is placed inside the underground mine silo. After placement, the crawler silt removal robot walks inside the underground mine silo and sucks and collects the silt. The collected silt is transported to the inside of the sand-water separator, and the silt water and sand and gravel are separated by the sand-water separator. After separation, the silt water is raised to the surface of the silo through the driving action of the sewage pump and the connection action of the steel wire hose, completing the silt removal operation inside the underground mine silo.

[0053] While the crawler silt cleaning robot is walking inside the underground water tank of the mine and sucking and collecting the silt, the feed head 401 at the front end of the crawler silt cleaning robot is inserted into the silt. After the feed head 401 is inserted, the silt is driven by the suction pump 302 and connected with the first conveying hose 303, the mounting pipe 304 and the first accordion pipe 305, so that the silt enters the interior of the feed head 401 from each group of through grooves 403 on the annular groove 402 and is conveyed to the interior of the collecting barrel 103 for collection. In the process of collecting the sucked silt inside the collecting barrel 103, as the silt flows into the collecting barrel 103 and the silt and the buoyancy pressure plate 2 are connected, the silt is sucked into the collecting barrel 103. The counteracting pushing action causes the buoyancy pressure plate 2 to move upward inside the collection tube 103 synchronously with the silt being collected inside the collection tube 103. During the upward movement of the buoyancy pressure plate 2, the L-shaped frame 901 is pushed to slide on the T-shaped rod 902, and the first spring 903 is deformed by force to generate elastic force. The first spring 903 pushes the L-shaped frame 901 and the buoyancy pressure plate 2 to squeeze and push, and the silt collected inside the collection tube 103 is squeezed. The silt is prevented from being strongly shaken due to the bumpy walking of the crawler dredging robot, thereby ensuring the stability of the crawler dredging robot in dredging, collecting and moving, and further ensuring the dredging effect.

[0054] In the process of silting and collecting, the crawler type silting robot drives the screw rod 705 to rotate through the driving motor 706. During the rotation of the screw rod 705, the screw rod 705 and the threaded sleeve 703 on the fixed plate 702 are meshed with each other to drive 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 fixed plate 702 and the mounting sleeve 701 are reciprocated between the two sets of fixed frames 704 through the sliding guide effect of each set of guide holes 801 and each set of guide rods 802. The movement of the mounting sleeve 701 drives the mounting pipe 304 and the feed head 401 to move synchronously. Through the movement of the feed head 401, it is convenient for the crawler dredging robot to collect dredging at different positions in the horizontal direction while moving. In the process of the feed head 401 moving to collect dredging at different positions in the horizontal direction, when the conical surface 5 on the feed head 401 abuts against the foreign matter at the dredging position, the feed head 401 is forced to retract toward the mounting pipe 304 through the pushing effect of the abutment between the conical surface 5 and the foreign matter. The retraction movement of the feed head 401 facilitates the automatic retraction of the feed head 401 after encountering an obstacle during the mobile dredging and collection process, thereby reducing the probability of the feed head 401 being damaged by encountering an obstacle during the dredging and collection process, and facilitating stable dredging and collection operations.
