Description

Technical Field

[0001] This invention relates to the field of coal mine drainage technology, and in particular to a drainage device for water accumulation on a flat surface in an open-pit coal mine. Background Technology

[0002] In open-pit coal mining, the flatbed, as an important component of bench mining, often accumulates water due to rainfall or groundwater seepage. The presence of water not only affects the efficiency of mining operations but may also cause problems such as slope instability and equipment corrosion. To ensure production safety, a drainage system is usually required to guide the water accumulated on the flatbed to a sump or drainage ditch in an orderly manner.

[0003] Traditional drainage methods often employ open ditches or pipes, but the complex environment of open-pit coal mines means that rocks, silt, and other impurities rolling down slopes can easily clog drainage channels, reducing drainage efficiency. Traditional ditch drainage structures are simple and ineffective at intercepting and separating particles of different sizes, leading to frequent blockages and low cleaning efficiency. Regular manual cleaning of accumulated silt and gravel increases maintenance costs. Therefore, a new open-pit coal mine flatbed water diversion device is needed to address the shortcomings of existing systems. Summary of the Invention

[0004] The purpose of this invention is to provide a drainage device for accumulated water in open-pit coal mines. This device can efficiently drain accumulated water from open-pit coal mines and can effectively intercept and separate particles of different sizes, avoiding blockage of drainage channels and achieving high cleaning efficiency.

The two sets of driving rods are symmetrically arranged at both ends of the guide channel. The surface of the driving rod is provided with external threads. The two driving rods pass through the connecting block and are threadedly connected to it. The driving rods can drive the connecting block to move along it, thereby causing the two sets of first pushing frames and the two sets of second pushing frames to move closer or further away from each other, so that the first pushing frames and the second pushing frames can move into the receiving frame and drop the material screened by the second screen plate onto the lifting plate.

One end of the control block is fixedly connected to the pusher plate, and the other end is fixedly connected to the outer side of the chain belt, enabling it to rotate around the two sets of sprockets.

[0013] Preferably, a third servo motor is fixed to the top of the receiving block, and the output end of the third servo motor is fixedly connected to the shaft of one of the sprockets. The chain belt is movably disposed inside the receiving block. The inside of the sewage channel is connected to the inside of the receiving frame, and both ends of the sewage channel are arc-shaped opening structures.

[0014] Preferably, the disc is a flat disc, and a groove is formed on the disc near the slope. Multiple sets of devices are continuously installed in the groove through the transition channel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, through the setting of the pushing component, can push the material screened by the first screen plate and the second screen plate into the receiving frame on different sides, thereby moving small particles, fine particles and mud-like materials to the lifting plate in a unified manner, and efficiently processing the material screened in the diversion channel. It can be applied to the scenario when there is a large amount of water accumulation in open coal mines, so that the diversion channel can maintain the ability to drain water. 2. The present invention, through the lifting component, can drive the lifting plate to move upward inside the receiving frame until the lifting plate moves to the inside of the sewage channel. At this time, all the dirty materials in the drainage channel are lifted up, preventing them from staying and accumulating at the bottom of the drainage channel, which helps to keep the water flowing smoothly at the bottom of the drainage channel. 3. The present invention, through the control components, pushes the dirt on the lifting plate along the inside of the drain channel, and all the dirt is pushed out from the opening at one end of the drain channel. When the lifting plate is raised again, the pusher moves in the opposite direction, so that the material can be pushed out from the opening at the other end of the drain channel. This allows the material to be piled up at different positions outside the diversion channel, which is convenient for subsequent unified cleaning, thereby improving the overall cleaning efficiency and preventing large particles, small particles, fine particles and mud from clogging the diversion channel. This allows materials of different sizes and types to be intercepted and discharged. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figure 1-8 As shown, this invention provides a drainage device for open-pit coal mine flatbed drainage, comprising: a drainage channel 1, which is a trough-type structure with an open top; transition channels 2 connected to the front and rear ends of the drainage channel 1 along its length; and adjacent drainage channels 1 connected by transition channels 2, thereby allowing the drainage device to be extended as needed to meet the actual needs of flatbed drainage. Receiving frames 3 are connected to both the left and right sides of the drainage channel 1, and receiving blocks 4 are connected to the outer sides of the receiving frames 3. A sewage discharge channel 5 is fixed to the top of the receiving blocks 4, which is used to discharge small particles and sludge. The side of the sewage discharge channel 5 is fixedly connected to the side of the drainage channel 1. A first screen plate 6 is provided at the top of the drainage channel 1 to prevent larger stones from falling into the interior of the drainage channel 1. A second screen plate 7 is fixed inside the drainage channel 1, which intercepts smaller particles and allows mud or fine particles to fall to the bottom of the drainage channel 1. A pushing component 8 is provided inside the diversion channel 1, and the pushing component 8 is movably connected to the second screen plate 7. It is used to push the material on the second screen plate 7 and the bottom of the diversion channel 1 into the receiving frame 3. A lifting plate 9 is slidably connected inside the receiving frame 3. A lifting component 10 is provided inside the receiving block 4. The lifting component 10 is fixedly connected to the lifting plate 9. The lifting component 10 is used to transfer the material falling onto the lifting plate 9 into the sewage discharge channel 5. The lifting plate 9 is L-shaped. A pushing plate 11 is movably connected inside the sewage discharge channel 5. A control component 12 is provided inside the receiving block 4, and the control component 12 is fixedly connected to the pushing plate 11. It is used to push the material on the lifting plate 9 out of the sewage discharge channel 5.

[0023] Specifically, the surface of the first sieve plate 6 is convex arc-shaped, which can improve its structural strength. Its surface is evenly distributed with sieve holes to prevent large rocks on the slope from falling into the diversion channel 1, while smaller particles can fall into the interior of the diversion channel 1 through the sieve holes. The second sieve plate 7 is flat and has several sieve grooves distributed in a linear array on it. The width of the sieve grooves is smaller than the width of the sieve holes, which is used to intercept smaller particles and allow mud or fine particles to fall to the bottom of the diversion channel 1.

[0024] Specifically, the feeding assembly 8 includes two sets of first push frames 801, two sets of second push frames 802, a connecting plate 803, a connecting block 804, and two sets of drive rods 805. The two sets of first push frames 801 are symmetrically arranged on the surface of the second screen plate 7, and the two sets of second push frames 802 are symmetrically arranged below the second screen plate 7. A connecting plate 803 is fixed to the opposite sides of the two sets of first push frames 801 and the opposite sides of the two sets of second push frames 802, and a connecting block 804 is fixed to both ends of the connecting plate 803. The two connecting blocks 804 are respectively positioned... At both ends of the diversion channel 1, two sets of drive rods 805 are symmetrically arranged at both ends of the diversion channel 1. The surface of the drive rods 805 is provided with external threads. The two drive rods 805 pass through the connecting block 804 and are threadedly connected to it. The rotation of the drive rods 805 can drive the connecting block 804 to move along it, thereby causing the two sets of first push frames 801 and two sets of second push frames 802 to move closer or further away from each other, so that the first push frames 801 and the second push frames 802 can move into the receiving frame 3 and drop the material screened by the second screen plate 7 onto the lifting plate 9. In the initial state, the symmetrical first push frame 801 and the second push frame 802 are fitted together, located exactly inside the drainage channel 1. Small particles fall through the first screen plate 6 to the inside of the first push frame 801, while muddy and fine particles fall through the second screen plate 7 to the inside of the second push frame 802. Both the first push frame 801 and the second push frame 802 are movably connected to the inside of the drainage channel 1. The bottom of the first push frame 801 is movably connected to the top of the second screen plate 7, and the top of the second push frame 802 is movably connected to the bottom of the second screen plate 7. The connecting plate 803 movably passes through the screen groove of the second screen plate 7. The first push frame 801... The first pusher 801 and the second pusher 802 can move away from each other and move to the inside of the receiving frame 3, thereby pushing the small particles inside the first pusher 801 to the inside of the receiving frame 3 and falling onto the lifting plate 9. The second pusher 802 can move away from each other and move to the inside of the receiving frame 3, thereby pushing the mud and fine particles inside the second pusher 802 onto the lifting plate 9. At this time, all the material falling into the inside of the diversion channel 1 is located on the lifting plate 9, and the material is not higher than the bottom of the second pusher 802, so that the first pusher 801 and the second pusher 802 move back into the inside of the diversion channel 1. If there is a lot of material, it will move multiple times into the inside of the receiving frame 3.

[0025] In this embodiment, the two sides of the drainage channel 1 are connected to the inner side of the receiving frame 3. The first push frame 801 is movably connected to the inner side of the receiving frame 3, the second push frame 802 is movably connected to the inner side of the receiving frame 3, the drive rod 805 is movably connected to the transition channel 2 through the rotating shaft, and the connecting block 804 is slidably connected to the inside of the transition channel 2. With the above structure, it is convenient to transfer small particles inside the first push frame 801 to the inner side of the receiving frames 3 on both sides, and it is convenient to transfer mud-like substances and fine particles inside the second push frame 802 to the inner side of the receiving frame 3.

[0026] like Figure 1, 2 As shown in Figure 6, multiple first through slots 13 are provided at both ends of the second push frame 802, and multiple second through slots 14 are provided at both ends of the diversion channel 1, with the first through slots 13 and the second through slots 14 connected. A through slot 15 is provided through the transition channel 2, and the through slot 15 is connected to the second through slots 14. When the second push frame 802 is completely located inside the diversion channel 1, the first through slots 13, the second through slots 14 and the through slot 15 are interconnected, allowing water to flow normally between different diversion channels 1. Because the mud and fine particles at the bottom of the diversion channel 1 can be cleaned in time, the first through slots 13 and the second through slots 14 can remain unobstructed, maintaining the drainage effect of the diversion channel 1.

[0027] In this embodiment, the feeding assembly 8 also includes a synchronous pulley 806 and a synchronous belt 807. The ends of the two sets of drive rods 805 are fixedly connected to the synchronous pulleys 806. The synchronous belt 807 is installed between the two sets of synchronous pulleys 806, and the synchronous pulleys 806 and the synchronous belt 807 constitute a belt drive structure. A first servo motor 16 is fixed inside a transition channel 2, and the output end of the first servo motor 16 is fixedly connected to one end of the drive rod 805. The first servo motor 16 can control the two drive rods 805 to rotate synchronously, and the drive rods 805 are threadedly connected to the connecting block 804. The transition channel 2 restricts the movement direction of the connecting block 804, thereby causing the connecting blocks 804 to move away from each other, driving the connecting plates 803 to move away from each other, thereby synchronously controlling the two sets of first push frames 801 to move away from each other, and the two sets of second push frames 802 to move away from each other. The first push frames 801 and the second push frames 802 on opposite sides simultaneously enter the receiving frame 3 on different sides, moving small particles, fine particles and mud to the lifting plate 9. It has a fast efficiency in handling dirt inside the diversion channel 1 and can be applied to scenarios where there is a large amount of water accumulation in open-pit coal mines. The diversion channel 1 can maintain the ability to drain water.

[0028] like Figure 7 , 8As shown, the lifting assembly 10 includes two sets of rotating rods 1001, a moving block 1002, a first bevel gear 1003, a second bevel gear 1004, and a synchronizing rod 1005. The two sets of rotating rods 1001 are symmetrically arranged vertically at both ends of the synchronizing rod 1005. The surface of the rotating rod 1001 is provided with external threads, and the rotating rod 1001 is movably connected to the moving block 1002 via threads. The first bevel gear 1003 and the second bevel gear 1004 are respectively driven and installed at the bottom end of the rotating rod 1001 and the outer periphery of the synchronizing rod 1005. The rotating rod 1001 is movably mounted inside the receiving block 4 via a bearing and meshes with the second bevel gear 1004. The moving block 1002 is fixedly connected to the side of the lifting plate 9. A fixing block 17 is provided inside the receiving block 4, and the rotating rod 1001 moves through the fixing block 17. The fixing block 17 is used to support the rotating rod 1001. The synchronizing rod 1005 is movably mounted at the bottom of the receiving block 4 via a rotating shaft. A second servo motor 18 is provided inside the receiving block 4, and the output end of the second servo motor 18 is fixedly connected to one end of the synchronizing rod 1005.

[0029] The second servo motor 18 is started, which drives the synchronous rod 1005 to rotate, causing the two second bevel gears 1004 to rotate synchronously. Since the first bevel gear 1003 meshes with the second bevel gear 1004, the two rotating rods 1001 rotate synchronously. Since the rotating rod 1001 is threadedly connected to the moving block 1002, and the receiving block 4 restricts the direction of movement of the moving block 1002, the moving block 1002 moves upward, driving the lifting plate 9 to move upward inside the receiving frame 3 until the lifting plate 9 moves to the inside of the sewage channel 5. At this time, all the material in the diversion channel 1 is lifted up, preventing it from staying and accumulating at the bottom of the diversion channel 1, which helps to keep the water at the bottom of the diversion channel 1 flowing smoothly.

[0030] like Figure 7 , 8 As shown, the control component 12 includes two sprockets 1201, a chain belt 1202, and a control block 1203. The two sets of sprockets 1201 are symmetrically arranged at both ends of the sewage channel 5, and the sprockets 1201 are rotatably mounted on the top of the receiving block 4 via a rotating shaft. The chain belt 1202 is driven and sleeved on the outer periphery of the two sprockets 1201, forming a chain drive structure. One end of the control block 1203 is fixedly connected to the push plate 11, and the other end is fixedly connected to the outer side of the chain belt 1202, and can rotate around the two sets of sprockets 1201. A third servo motor 19 is fixed on the top of the receiving block 4, and the output end of the third servo motor 19 is fixedly connected to the shaft of one of the sprockets 1201. The chain belt 1202 is movably disposed inside the receiving block 4. The inside of the sewage channel 5 is connected to the inside of the receiving frame 3, and the two ends of the sewage channel 5 are arc-shaped opening structures, which can be conveniently pushed out by the arc-shaped opening structure for accumulation during the rotation of the pusher plate 11 with the sprocket 1201, which is convenient for subsequent processing.

[0031] In use, the third servo motor 19 is started, driving one sprocket 1201 to rotate. Under the action of the other sprocket 1201, the chain belt 1202 rotates inside the receiving block 4. Since the control block 1203 is connected to the chain belt 1202 and the pusher plate 11 at the same time, the pusher plate 11 needs to move along the inner side of the drain channel 5. The two ends of the drain channel 5 are arc-shaped openings. The pusher plate 11 pushes the material on the lifting plate 9 to move along the inside of the drain channel 5, and all the material is pushed out from the opening at one end of the drain channel 5. When the lifting plate 9 is lifted again, the pusher plate 11 moves in the opposite direction, which can push the material out from the opening at the other end of the drain channel 5. This allows the material to be piled up at different positions outside the diversion channel 1, which is convenient for subsequent unified cleaning. This improves the overall cleaning efficiency and prevents large particles, small particles, fine particles and mud from clogging the diversion channel 1, so that dirt of different sizes and types can be intercepted and discharged.

[0032] like Figure 9 As shown, the application scenario of the drainage device of the present invention is as follows: The disc 20 is a flat disc, and a groove is opened at the position of the disc 20 near the slope 21. Multiple sets of devices are continuously installed in the groove through the transition channel 2. There is a lot of water accumulation at the connection between the disc 20 and the slope 21, and it is easy to drain. Particles or mud and sand can easily roll on the slope 21 and fall onto the device.

[0033] The working principle of this invention is as follows: In operation, water, mud, fine particles, small particles, and large particles will first fall from the coal mine flatbed onto the drainage channel 1. The first screen plate 6 can block the large particles, and the second screen plate 7 can block the small particles. The remaining water, mud, and fine particles will fall to the bottom of the drainage channel 1. Under the action of the synchronous pulley 806 and the synchronous belt 807, the two drive rods 805 can be controlled to rotate synchronously by a single first servo motor 16, and the drive rods 805 are threadedly connected to the connecting block 804. The transition channel 2 restricts the movement direction of the connecting block 804, thereby causing the connecting blocks 804 to move away from each other, which in turn causes the connecting plates 803 to move away from each other. This synchronously controls the two first push frames 801 to move away from each other, and the two second push frames 802 to move away from each other. The first push frames 801 and the second push frames 802 on opposite sides simultaneously enter the receiving frames 3 on different sides, moving small particles, fine particles, and mud-like materials onto the lifting plate 9. Then, the second servo motor 18 is started, driving the synchronizing rod 1005 to rotate, causing the two second bevel gears 10 to rotate. 04. Synchronous rotation: Due to the meshing of the first bevel gear 1003 and the second bevel gear 1004, the two rotating rods 1001 rotate synchronously. Since the rotating rods 1001 are threadedly connected to the moving block 1002, and the receiving block 4 restricts the movement direction of the moving block 1002, the moving block 1002 moves upward, causing the lifting plate 9 to move upward inside the receiving frame 3 until the lifting plate 9 moves to the inside of the sewage channel 5, at which point all the material in the diversion channel 1 is lifted up. Finally, the third servo motor 19 is started, driving a sprocket 1201 to rotate. Under the action of another sprocket 1201, the chain belt 1202 rotates inside the receiving block 4. Since the two ends of the control block 1203 are connected to the chain belt 1202 and the pusher plate 11 respectively, the pusher plate 11 needs to move along the inner side of the sewage channel 5. The two ends of the sewage channel 5 are arc-shaped opening structures. The pusher plate 11 pushes the material on the lifting plate 9 to move along the inside of the sewage channel 5, and all the material is pushed out from the opening at one end of the sewage channel 5. When the lifting plate is lifted again, the pusher plate 11 moves in the opposite direction, so that the material is pushed out from the opening at the other end of the sewage channel 5.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
