Description

Technical Field

[0001] This invention relates to the field of water ecological restoration technology, specifically to a water ecological restoration device and method for high-altitude mining areas. Background Technology

[0002] Existing mining areas are equipped with wastewater treatment systems to purify and treat polluted wastewater generated during mining before centralized discharge. However, the water pollution factors within mining areas are highly complex, and some pollutants cannot be centrally managed. Among these, the greatest risk to groundwater ecology comes from goaf water. Goaf water refers to the water that gradually accumulates and stagnates in open mine pits after mining operations. This water reacts with residual ore and tailings over a long period, transforming into highly concentrated acidic water or heavy metal wastewater. Under normal conditions, this polluted water gradually infiltrates the goaf. Rainfall further accelerates this infiltration, ultimately causing groundwater pollution. Therefore, goaf water is one of the main sources of groundwater pollution. To address the problem of water ecology pollution in mining areas at its source and implement water ecology restoration, a series of treatments are needed, including draining the goaf water, laying impermeable layers, and landfilling.

[0003] When draining water from mined-out areas, it is necessary to purify the water. Purification methods include centralized purification and in-situ purification. Centralized purification requires the establishment of a systematic drainage network. However, mined-out areas are widely and scattered within mining areas, with varying sizes, water volumes, and terrain, making the construction of drainage networks difficult, costly, and less applicable. In-situ purification methods are mainly divided into ecological purification and chemical purification. Ecological purification achieves purification by introducing animals or planting plants in the polluted water area. However, this method has high environmental requirements; in high-altitude mining environments, purification conditions are difficult to maintain, and purification efficiency is low. Furthermore, given the closer groundwater is to the surface in high-altitude areas, it cannot quickly address the risk of polluted water seepage. Chemical purification methods are characterized by high efficiency and wide applicability. However, the water in mined-out areas is stagnant, requiring more precise application of chemical purifiers. Only by ensuring a full reaction between the water and the chemical purifier can efficient and comprehensive purification be achieved, placing high demands on operational conditions. In view of existing methods for purifying polluted water in mining subsidence areas, and in order to improve purification efficiency and convenience, and thus achieve source restoration of the water ecology in mining areas, this invention proposes a water ecology restoration device and method for high-altitude mining areas. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for water ecological restoration in high-altitude mining areas in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] This invention provides a water ecological restoration device for high-altitude mining areas, including an onshore module and a floating module. The floating module includes a water supply pipe, an extension water pipe connected to the water supply pipe, and two angle-adjustable floating boxes located on both sides of the water supply pipe. The floating boxes are equipped with independent pumping mechanisms and feeding mechanisms. The onshore module includes a traction mechanism for moving the floating boxes on the water surface and a feeding mechanism for supplying purifying agents to the feeding mechanism.

[0007] The feeding mechanism includes a feed pipe, a primary conveying curtain, a feed pipe, and a secondary conveying curtain connected in sequence. The secondary conveying curtain is used to add purifying agent into the water to purify the water. When the feed pipe rotates, it winds up and unwinds the primary and secondary conveying curtains.

[0008] The pumping mechanism includes a water bladder that expands during the pumping process, and the expansion of the water bladder pushes the conveying pipe to wind up the primary and secondary conveying curtains.

[0009] As a further optimization of the present invention, two symmetrically distributed No. 1 rope winding machines are provided on the water supply pipe, and the free ends of the two suspension ropes pulled out from the No. 1 rope winding machines are respectively fixed to the far ends of the two floating boxes.

[0010] As a further optimization of the present invention, the pumping mechanism also includes a pumping pipe disposed inside the water bladder for pumping water from the water area, a return pipe for injecting water into the water bladder, a drain pipe for connecting the water bladder and the water supply pipe, and a pumping assembly disposed outside the floating box and connected to the pumping pipe. The pumping pipe and the return pipe are connected by a water pump, and an elastic sealing element is provided at the inlet of the drain pipe.

[0011] As a further optimization of the present invention, gears are provided at both ends of the material tube, and a row of teeth that cooperate with the gears are provided in the floating box. Pushing members for resetting the material tube are provided on both sides of the primary conveying curtain. The pushing members include an arc-shaped plate that fits with the material tube, and the arc-shaped plate is elastically slidably connected to the floating box through a spring and a groove at the bottom.

[0012] As a further optimization of the present invention, the feed pipe passes through the floating box, the secondary conveying curtain has evenly distributed discharge ports, and the bottom of the secondary conveying curtain is provided with a counterweight bar, and the bottom of the floating box is provided with a through groove that cooperates with the counterweight bar.

[0013] As a further optimization of the present invention, the shore module includes two trolleys consisting of a traction mechanism and a feeding mechanism, and the two trolleys correspond one-to-one with the two floating boxes. The feeding mechanism includes a feeding seat equipped with wheels, a material bucket placed on the feeding seat and communicating with the feeding seat, and an extension pipe for communicating with the feeding seat and the feed pipe. The traction mechanism includes a traction rope located at the outer end of the two floating boxes and a second rope winding machine located at the bottom of the feeding seat. The second rope winding machine is used to wind and unwind the traction rope.

[0014] As a further optimization of the present invention, a floating component is rotatably mounted on the floating box.

[0015] As a further optimization of the present invention, the pumping assembly includes two slide rail frames located at the bottom of the floating box, and several movable frames are provided between the two slide rail frames. The movable frames are slidably connected to the slide rail frames by sliders on both sides, and adjacent movable frames are elastically connected by connectors. Several suction pipes are provided on the movable frames, and the inlets of the suction pipes correspond one-to-one with the inlets of the pumping pipes. The movable frames have a U-shaped structure and the openings are covered with filter screens. The inlets of the suction pipes extend to the inside of the movable frames. A floating ring is provided on one of the movable frames that is away from the water supply pipe.

[0016] The present invention also provides a method for water ecological restoration in high-altitude mining areas using the above-mentioned restoration device, comprising the following steps:

[0017] S1. Place the floating module into the goaf with water accumulation problem, pull the extension water pipe to the drainage ditch or reinjection well, and prepare the purification agent and store it in the feeding mechanism of the onshore module.

[0018] S2. Activate the feeding mechanism of the shore module to feed the purifying agent into the feeding mechanism. At the same time, adjust the traction mechanism to move the floating box on the water surface and drive the feeding mechanism to evenly distribute the purifying agent into the water accumulation area.

[0019] S3. After the purifying agent reacts fully with the accumulated water, the pumping mechanism is turned on to drain the accumulated water. The water bladder expands, causing the material pipe in the feeding mechanism to rotate and rewind the primary and secondary material conveying curtains. The pumping mechanism continues to pump water, and the purified accumulated water is discharged along the extended water pipe.

[0020] As a further optimization of the present invention, in S3, during the process of draining the accumulated water, in the later stage of drainage, the angle of the two floating boxes is adjusted so that the floating module is narrowed as a whole to adapt to different pit bottom structures.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. For mined-out areas that are scattered throughout the mine and vary in size, water volume, and topography, the high-altitude mining area water ecological restoration device and restoration method based on the device provided by this invention can perform one-time in-situ restoration of water in each mined-out area. Specifically, it includes a complete process of purification followed by drainage. The purified water can be discharged into nearby recharge wells or drainage ditches. This restoration method is convenient to operate, highly flexible, widely applicable, and low in cost.

[0023] 2. During the restoration process, facing goaf areas with different terrains, ranges, and water accumulation, on the one hand, the vertically deployable secondary conveying curtain, in conjunction with the movement of the floating box, can evenly distribute the purifying agent to various areas and depths of the water, so that the accumulated water can be purified evenly, comprehensively, and efficiently. On the other hand, the floating box can adapt to different pit bottom terrain conditions by unfolding and folding, and can sink into irregular pit bottoms to pump water in the entire range, so as to achieve the effect of emptying the accumulated water as much as possible, reducing the workload of subsequent treatment of the goaf area. Moreover, throughout the restoration process, operators only need to perform onshore operations, making the operation convenient and efficient. Attached Figure Description

Detailed Implementation

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example 1

[0033] like Figure 1-7 As shown, the high-altitude mining area water ecological restoration device of this embodiment includes a shore module and a floating module. The floating module includes a water supply pipe 1, an extension water pipe 21 connected to the water supply pipe 1, and two angle-adjustable floating boxes 2 located on both sides of the water supply pipe 1. The floating boxes 2 are equipped with independent pumping mechanisms and feeding mechanisms. The shore module includes a traction mechanism for moving the floating boxes 2 on the water surface and a feeding mechanism for supplying purification agents to the feeding mechanism.

[0034] The feeding mechanism includes a feed pipe 5, a primary conveying curtain 14, a conveying pipe 12, and a secondary conveying curtain 15 connected in sequence. The secondary conveying curtain 15 is used to add purifying agent into the water to purify the water. When the conveying pipe 12 rotates, it winds up and unwinds the primary conveying curtain 14 and the secondary conveying curtain 15.

[0035] The pumping mechanism includes a water bladder 6 that expands during the pumping process, and the expansion of the water bladder 6 pushes the conveying pipe 12 to wind up the primary conveying curtain 14 and the secondary conveying curtain 15.

[0036] The method for restoring the aquatic ecosystem in high-altitude mining areas using the aforementioned restoration device includes the following steps:

[0037] S1. Place the floating module into the goaf with water accumulation problem, pull the extension water pipe 21 to the drainage ditch or reinjection well, and prepare the purification agent and store it in the feeding mechanism of the onshore module.

[0038] S2. Activate the feeding mechanism of the shore module to feed the purifying agent into the feeding mechanism. At the same time, adjust the traction mechanism to move the floating box 2 on the water surface and drive the feeding mechanism to evenly distribute the purifying agent into the water accumulation area.

[0039] Specifically, in the initial state, the secondary conveying curtain 15 is in the unfolded state and submerged in water. After the feeding mechanism is turned on, the purifying agent is injected into the feeding mechanism and then passes through the feed pipe 5, the primary conveying curtain 14, the conveying pipe 12 and the secondary conveying curtain 15 in sequence, and finally mixes into the water. During this process, by moving the position of the shore mechanism and adjusting the traction mechanism, the floating box 2 is moved on the water surface, thereby driving the secondary conveying curtain 15 to move in the water, injecting the purifying agent into various directions and depths in the water, so that the purifying agent can fully contact the water and achieve the effect of full-range purification.

[0040] S3. After the purifying agent reacts fully with the accumulated water, the pumping mechanism is turned on to drain the accumulated water. The water bladder 6 expands, causing the conveying pipe 12 in the feeding mechanism to rotate, and the primary conveying curtain 14 and the secondary conveying curtain 15 are rolled up. The pumping mechanism continues to pump water, and the purified accumulated water is discharged along the extension water pipe 21.

[0041] Specifically, after the pumping mechanism is turned on, the water flow first enters the water bladder 6 to make it expand. During the expansion of the water bladder 6, it pushes the conveying pipe 12, causing the conveying pipe 12 to rotate, thereby winding up the primary conveying curtain 14 and the secondary conveying curtain 15.

[0042] Subsequently, the water flows into the water supply pipe 1 and is discharged through the extended water pipe 21 to achieve the effect of clearing the accumulated water. During this process, in the later stage of drainage, after the uneven pit bottom structure of the goaf is exposed, the angle of the two floating boxes 2 can be adjusted to narrow the floating module as a whole, so that the near end of the two floating boxes 2 can be buried in the narrow water pit to continuously pump water, so as to empty the accumulated water in one go as much as possible.

[0043] When using the above-mentioned remediation method to purify and clean up the accumulated water in the goaf of a mining area to achieve the effect of restoring the aquatic ecology of the mining area, on the one hand, the device can be used anywhere without regional limitations and can achieve on-site purification and drainage. It is widely adaptable and flexible in use for goafs characterized by large-scale dispersion, large differences in water volume, and large differences in topography. On the other hand, the remediation device can continuously perform the work of adding purifying agents and pumping out accumulated water. Operators only need to operate on the shore. When adding purifying agents, the deployment of the secondary conveying curtain 15 can achieve a large-scale dynamic addition effect, allowing the purifying agents to be evenly dispersed in the water area, which helps to accelerate the purification speed and improve the purification effect. When pumping out accumulated water, it can pump out accumulated water from top to bottom. Through the rotation and opening and closing of the two floating boxes 2, it can adapt to the irregular terrain of the goaf pit bottom, maximize the drainage effect, and reduce the workload of subsequent goaf backfilling. In summary, using this remediation device can greatly improve the efficiency and convenience of treating accumulated water in goafs.

[0044] Preferably, the water supply pipe 1 is equipped with two symmetrically distributed No. 1 rope winding machines 3. The free ends of the two suspension ropes 4 pulled out from the No. 1 rope winding machine 3 are respectively fixed to the far ends of the two floating boxes 2. In the initial state, the two floating boxes 2 are both in a horizontal state. The No. 1 rope winding machine 3 winds up the suspension ropes 4, which can drive the far ends of the two floating boxes 2 to gradually rise. The included angle between the two floating boxes 2 gradually decreases, and the overall size of the floating module gradually narrows, so that the floating module can sink into the bottom area of ​​pits of different sizes for pumping water.

[0045] Preferably, the pumping mechanism further includes a pumping pipe 7 located inside the water bladder 6 for pumping water from the water area, a return pipe 9 for injecting water into the water bladder 6, a drain pipe 10 for connecting the water bladder 6 and the water supply pipe 1, and a pumping assembly 8 located outside the floating box 2 and connected to the pumping pipe 7. The pumping pipe 7 and the return pipe 9 are connected by a water pump. An elastic sealing element 11 is provided at the inlet of the drain pipe 10. The elastic sealing element 11 can be an elastic sealing plug or an elastic sealing membrane. After the water pump is turned on, under the action of the water pump, the accumulated water in the goaf passes through the pumping assembly 8, the pumping pipe 7, the water pump, and the return pipe 9 in sequence and enters the water bladder 6. Then the water bladder 6 is filled, and the water pressure inside the water bladder 6 gradually increases. Finally, the water pressure breaks open the elastic sealing element 11, and the water flow can enter the water supply pipe 1 through the drain pipe 10. Finally, it is discharged into the drainage ditch or recharge well through the extension water pipe 21.

[0046] Preferably, gears 13 are provided at both ends of the conveying pipe 12, and the floating box 2 is provided with a row of teeth that cooperate with the gears 13. Pushing members 19 for resetting the conveying pipe 12 are provided on both sides of the primary conveying curtain 14. The pushing member 19 includes an arc-shaped plate that fits against the conveying pipe 12, and the arc-shaped plate is elastically slidably connected to the floating box 2 through a spring and a bottom groove.

[0047] When the material conveying pipe 12 and the gear 13 are connected as a whole and bear the lateral thrust, the gear 13 will move along the tooth row, thereby driving the material conveying pipe 12 to rotate, and then unwinding and rewinding the primary material conveying curtain 14 and the secondary material conveying curtain 15. When pumping water, the secondary material conveying curtain 15 is rolled up, which can prevent the unfolded secondary material conveying curtain 15 from covering the pumping assembly 8 under the suction force, thus affecting the pumping efficiency.

[0048] After the water pumping is completed, the water bladder 6 naturally rebounds, the stored water inside is squeezed out, the water bladder 6 no longer applies a pushing force to the conveying pipe 12, the pusher 19 gradually rebounds, and the conveying pipe 12 returns to its initial position. During the process, the primary conveying curtain 14 and the secondary conveying curtain 15 are also unrolled and restored to their initial state.

[0049] Preferably, the feed pipe 5 passes through the floating box 2, and the secondary conveying curtain 15 has evenly distributed discharge ports 16. The bottom of the secondary conveying curtain 15 is provided with a counterweight bar 17, and the bottom of the floating box 2 is provided with a through groove 18 that cooperates with the counterweight bar 17. The counterweight bar 17 allows the secondary conveying curtain 15 to be vertically unfolded in the water, so as to achieve the effect of simultaneously dispensing purifying agents into waters of different depths. After the secondary conveying curtain 15 is rolled up, the counterweight bar 17 engages with the through groove 18 and is fixed. When unrolling, the counterweight bar 17 pulls the secondary conveying curtain 15 to unfold.

[0050] Preferably, the shore module includes two trolleys consisting of a traction mechanism and a feeding mechanism, and the two trolleys correspond one-to-one with the two floating boxes 2. The feeding mechanism includes a material conveying seat 25 equipped with wheels, a material bucket 26 placed on the material conveying seat 25 and communicating with the material conveying seat 25, and an extension material pipe 22 for communicating with the material conveying seat 25 and the feed pipe 5. The traction mechanism includes a traction rope 23 located at the outer end of the two floating boxes 2 and a second rope winding machine 24 located at the bottom of the material conveying seat 25. The second rope winding machine 24 is used to wind and unwind the traction rope 23.

[0051] Preferably, a float 20 is rotatably mounted on the float box 2. When the angle of the float box 2 is adjusted, the float 20 can rotate automatically and always float on the water surface, ensuring that the float box 2 can always float in the water, and the water pumping component 8 can always be submerged in the water to pump water.

[0052] Preferably, the pumping assembly 8 includes two slide rail frames 801 located at the bottom of the floating tank 2, with a plurality of movable frames 802 between the two slide rail frames 801. The movable frames 802 are slidably connected to the slide rail frames 801 via sliders 803 on both sides, and adjacent movable frames 802 are elastically connected via connectors 804. Each movable frame 802 has a plurality of suction pipes 805, and each suction pipe 805 corresponds one-to-one with the inlet of the pumping pipe 7. The movable frame 802 has a U-shaped structure, and its opening is covered with a filter screen. The inlet extends to the inside of the movable frame 802. A float ring 806 is provided on one of the movable frames 802 that is far away from the water supply pipe 1. When the float box 2 is tilted, the pumping assembly 8 can automatically adapt to the water level conditions under various water level conditions. Specifically, the movable frame 802 connected with the float ring 806 is closest to the water surface, while the remaining movable frames 802 are located at a deeper water level. All the suction ports of the suction pipes 805 will be submerged in the water to draw water, which can prevent the suction pipes 805 from drawing in air and is conducive to maintaining the highest pumping efficiency.

[0053] It should be emphasized that the return pipe 9, the drain pipe 10, the section of the pumping pipe 7 located outside the floating box 2, the extension water pipe 21, and the extension feed pipe 22 all use deformable flexible hoses, preferably elastic telescopic pipes. Furthermore, the water pump and the first rope winding machine 3 are both equipped with remote control switches, and a battery and solar panel for long-term power supply can be configured on the water supply pipe 1. The above embodiments only illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
