[0029] According to an embodiment of the utility model, a dam body device for an open-pit coal mine dump is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0031] With the help of the above technical scheme, the utility model realizes the protection of the open-air coal yard dump in bad weather under the cooperation of the coal mine dump slope protection 3, grid plate 1 4, barrier trough 5, sedimentation tank 6, slag discharge component 7, adjustment component 8 and gate plate 9, thereby ensuring the safety of the open-air coal yard dump. Under the cooperation of the slag discharge component 7 and the grid plate 2 13, the grid plate 2 13 is used to block the silt in the water, and the slag discharge component 7 is used to discharge the silt to the bottom of the sedimentation tank 6. Under the cooperation of the adjustment component 8 and the gate plate 9, the adjustment component 8 is used to open the gate plate 9 and discharge the silt from the bottom of the sedimentation tank 6, thereby ensuring the safety protection of the dam body.

[0032] In one embodiment, for the above-mentioned slag discharge component 7, the slag discharge component 7 includes an arched diverter slope 701 arranged inside the sedimentation tank 6, a diverter plate 702 is arranged on the surface of the arched diverter slope 701, and a plurality of diverter blocks 703 are evenly arranged at both ends of the surface of the diverter plate 702. The diverter block 703 includes a diverter protrusion 7031 arranged on one side of the diverter plate 702, and a rounded corner 7032 is arranged at the end of the diverter protrusion 7031. The surface of the diverter protrusion 7031 is close to the top of the arched diverter slope 701. One end is inclined, so that under the action of the slag discharge component 7, the silt can be discharged to the bottom end of the sedimentation tank 6, thereby facilitating the subsequent collection of silt and improving the working efficiency of the entire dam body device.

[0033] The working principle of the slag discharge component 7 is as follows: first, the silt in the water blocked by the grid plate 13 will slide to the two ends of the arched diversion slope 701 under the action of the arched diversion slope 701. At the same time, with the cooperation of the diversion plate 702 and the diversion block 703, the design of the rounded corner 7032 reduces the resistance of the silt during the sliding process. The surface of the diversion protrusion 7031 is close to the top of the arched diversion slope 701. One end is inclined, so that the silt can slide smoothly downward along the inclined surface, thereby effectively guiding the silt into the bottom of the sedimentation tank 6.

[0034] In one embodiment, for the above-mentioned adjustment component 8, the adjustment component 8 includes a motor 801 arranged at the top of the base plate 1, a bevel gear 802 is arranged at one end of the output shaft of the motor 801, a bevel gear 802 is arranged at the bottom end of the bevel gear 802 and a bevel gear 803 meshing therewith is arranged, a screw rod 804 is inserted in the middle of the bevel gear 803, and a bearing seat 805 matching with the gate plate 9 is arranged at the bottom end of the screw rod 804; a bearing seat 806 matching with the base plate 1 is arranged at the bottom end of the bevel gear 803, so that under the action of the adjustment component 8, the gate plate 9 can be driven to slide in the vertical direction, and when mud and sand accumulate at the bottom end of the slag discharge component 7, the gate plate 9 is opened to clean out the internal mud and sand, thereby ensuring the stable use of the dam body device.

[0035] The working principle of the adjustment component 8 is as follows: under the control of the external control panel, the motor 801 is controlled and started, and the bevel gear 1 802 is driven to rotate under the positive rotation of the output shaft of the motor 801, and the bevel gear 1 802 is used to drive the meshing bevel gear 2 803 to rotate, and under the action of the bearing seat 2 806, the stability of the bevel gear 2 803 is guaranteed. At the same time, during the rotation of the bevel gear 2 803, the bearing seat 1 805 is used to drive the screw rod 804 to rotate, and the gate plate 9 is moved upward in the vertical direction, thereby opening the gate. Conversely, the output shaft of the motor 801 is controlled to reverse to achieve the closing of the gate plate 9.

[0036] In one embodiment, for the above-mentioned through hole 11 , limiting grooves 1101 cooperating with the gate plate 9 are provided at both ends of the through hole 11 , so that under the action of the limiting grooves 1101 , the stable movement of the gate plate 9 in the vertical direction is guaranteed.

[0037] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0038] In actual application, when the overflowing water and silt flow through the dam of the open-pit coal mine dump, the large particles of silt are blocked by the action of the grid mesh 4, so that the large particles of sand and gravel are collected by the blocking groove 5. When the water and silt pass through the grid mesh 4, the flow rate of the water and silt is blocked by a plurality of strip-shaped buffer baffles on the surface of the coal mine dump slope 3. When the water and silt flow to the grid plate 2 13 on one side of the sedimentation tank 6, the fine silt is blocked by the grid plate 2 13, so that the silt is blocked to the surface of the slag discharge component 7 of the sedimentation tank 6, so that the silt can slide smoothly downward along the inclined surface, thereby effectively guiding the silt into the bottom end of the sedimentation tank 6. At the same time, the control adjustment component 8 drives the gate plate 9 to open and completes the discharge of silt. The screened water flows into the collection tank 14 and is collected.

[0039] The working principles of the slag discharge assembly 7 and the adjustment assembly 8 are as shown above.

[0040] In summary, with the help of the above technical scheme of the utility model, the utility model realizes the protection of the open-air coal yard dump in bad weather under the cooperation of the coal mine dump slope protection 3, the grid plate 1 4, the barrier trough 5, the sedimentation tank 6, the slag discharge component 7, the adjustment component 8 and the gate plate 9, and ensures the safety of the open-air coal yard dump.
