Description

Technical Field

[0001] The invention relates to the technical field related to tailings ponds, and specifically to a tailings pond drainage device. Background Art

[0002] A tailings pond is a dammed valley or enclosed area used to store tailings or other industrial waste after ore sorting in metal or non-metallic mines. Drainage devices are internal drainage facilities within the dam. The higher the water level within the tailings pond, the worse the dam's stability and the greater the likelihood of earthquake liquefaction. Installing drainage devices within the dam can effectively lower the water level and facilitate the drainage and consolidation of tailings mud, thereby enhancing dam stability.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] Please refer to Figure 1-14 , the invention provides a technical solution:

[0042] A tailings pond drainage device is provided, wherein a drainage ditch 2 is provided around the outer side of the tailings pond 1, and a plurality of drainage devices 3 evenly distributed vertically are provided on the dam of the tailings pond 1 on each side;

[0043] The drainage device 3 includes a drainage channel 4 extending horizontally from the interior of the tailings pond 1 to the drainage ditch 2. The drainage channel 4 is sealed with a drainage valve 5 capable of vertically intercepting the inside of the drainage channel 4, and the upper side of the drainage valve 5 is connected to the dam of the tailings pond 1.

[0044] A vertically arranged gear row 6 is provided on one side above the seepage valve 5, and a drive motor 7 is provided next to the seepage valve 5. A drive gear 8 that is always engaged with the gear row 6 is docked on the rotating shaft of the drive motor 7, and a control box 9 is also provided on one side of the drive motor 7;

[0045] The interior of the drainage valve 5 is equipped with a positioning card seat 10 that is vertically arranged and can move up and down. The two sides of the positioning card seat 10 are respectively provided with mutually symmetrical positioning grooves 11. The interior of the drainage valve 5 is also equipped with a horizontally arranged and movable elastic positioning shaft 12 at the position corresponding to the positioning groove 11. Guide blocks 13 are fixed on both sides of the elastic positioning shaft 12. The guide blocks 13 are through-assembled on the guide shaft 14. The first spring 15 is also nested on the guide shaft 14. A vertically arranged float 16 is fixed to the bottom of the positioning card seat 10. A trigger seat 17 fixed to the interior of the drainage valve 5 is equipped above the positioning card seat 10. The trigger seat 17 is internally equipped with a trigger rod 18 that is vertically arranged and can move up and down. The lower end of the trigger rod 18 is fixed to the positioning card seat 10. The upper end of the trigger rod 18 is fixed with a limit block 19. A vertically arranged trigger head 20 is fixed below the limit block 19. A trigger hole 21 is opened above the trigger seat 17 at the position corresponding to the trigger head 20. A first annular trigger piece 22 and a second annular trigger piece 23 are arranged in upper and lower distributions inside the trigger hole 21. Guide blocks 24 are fixed on both sides of the first annular trigger piece 22. The guide blocks 24 are assembled on the guide shaft 25 through the guide shaft 25. A second spring 26 is also embedded in the guide shaft 25.

[0046] A magnet 27 is also provided in the cavity where the drainage valve 5 is located.

[0047] In the above description, the drainage channel 4 flows from the inside of the tailings pond 1 to the inside of the drainage ditch 2, and a filter screen 28 is provided at the entrance thereof.

[0048] In the above description, the tailings pond 1 can be provided with multiple layers of drainage devices 3 on the dam. The drainage channels 4 in each layer of the drainage devices 3 have different heights. The drainage valve 5 in the lower drainage channel 4 penetrates the upper drainage channel 4. The drainage valve 5 is further provided with an avoidance cavity 29 at the intersection of the upper drainage channel 4.

[0049] When the drainage valve 5 in the drainage channel 4 is closed, the avoidance cavity 29 provided on the drainage valve 5 will be communicated with the drainage channel 4 above.

[0050] In the above, the elastic positioning shaft 12 can be assembled in the positioning groove 11 to fix the positioning base 10, wherein the elastic positioning shaft 12 is made of iron material that can be attracted by a magnet;

[0051] When the drainage valve 5 fully opens the drainage channel 4, the elastic positioning shaft 12 follows the drainage valve 5 to reach the position of the magnet 27, and the magnet 27 can adsorb the elastic positioning shaft 12, thereby compressing the first spring 15. At this time, the elastic positioning shaft 12 can be separated from the positioning groove 11, and the positioning base 10 is no longer fixed.

[0052] In the above description, the end of the elastic positioning shaft 12 is an arc head, and the positioning groove 11 is an arc surface groove.

[0053] In the above description, when there is no external force acting on the first annular trigger piece 22 inside the trigger seat 17, the first annular trigger piece 22 will not contact the second annular trigger 23;

[0054] When the float 16 falls to the bottom of the drainage channel 4 , the trigger head 20 can just pass through the trigger hole 21 , pressing the first annular trigger piece 22 so that it contacts the second annular trigger 23 .

[0055] In the above description, the first ring-shaped trigger piece 22 and the second ring-shaped trigger 23 are both conductive, and the trigger head 20 is a non-conductive body.

[0056] In the above, the control box 9 is composed of two time relays and a control switch;

[0057] One of the time relays is electrically connected to the forward steering switch of the drive motor 7, and the start switch of the time relay is electrically connected to the control switch. After the time relay controls the drive motor 7 to start, the drainage valve 5 can move upward, thereby realizing the opening of the drainage valve 5 in the drainage channel 4;

[0058] Another time relay is electrically connected to the reverse steering switch of the drive motor 7. The starting switch of this time relay is connected to the first ring-shaped trigger plate 22 and the second ring-shaped trigger 23 through wires respectively. After this time relay controls the start of the drive motor 7, the drainage valve 5 can move downward, thereby realizing the closure of the drainage valve 5 in the drainage channel 4.

[0059] Working principle of the present invention:

[0060] According to the height of the actual infiltration line, select the drainage channel 4 of appropriate height for drainage;

[0061] When the cam 12 is fully opened, the water in the tailings pond 1 flows into the drainage ditch 2 through the drainage channel 4. At this time, the elastic positioning shaft 12 follows the drainage valve 5 to reach the position of the magnet 27. The magnet 27 can absorb the elastic positioning shaft 12, thereby compressing the first spring 15. At this time, the elastic positioning shaft 12 can be separated from the positioning groove 11. At this time, the positioning base 10 is no longer fixed. Since the bottom of the positioning base 10 is a float 16, there is water flowing in the drainage channel 4, so the float 16 does not contact the bottom of the drainage channel 4.

[0062] When the water in the drainage channel 4 has finished flowing, the float 16 will fall to the bottom of the drainage channel 4 under the action of gravity. When the float 16 falls to the bottom of the drainage channel 4, the trigger head 20 can just pass through the trigger hole 21, pressing the first ring-shaped trigger piece 22 to make it contact with the second ring-shaped trigger 23. Since the first ring-shaped trigger piece 22 and the second ring-shaped trigger 23 are both conductive, the trigger head 20 is non-conductive, and another time relay start switch in the control box 9 is connected to the first ring-shaped trigger piece 22 and the second ring-shaped trigger piece 23 through wires. The trigger piece 22 is connected to the second ring-shaped trigger 23. At this time, the starting switch of the time relay here forms a closed loop and is triggered to start. At this time, the shaft of the drive motor 7 rotates in the opposite direction, and the drive gear 8 and the gear row 5 are driven to realize the downward movement of the drainage valve 5, from until the drainage valve 5 is completely closed in the drainage channel 4. After the drainage valve 5 is completely closed in the drainage channel 4, the elastic positioning shaft 12 returns to its position, and it can be assembled in the positioning groove 11 to fix the positioning seat 10, so as to realize the cycle to realize opening / closing.

[0063] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations that come within the meaning and range of equivalents of the claims are intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
