Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological restoration, in particular to a mine pit water body restoration system and process based on landscape optimization. BACKGROUND

[0002] As a large coal production and consumption country in the world, China has been carrying out large-scale coal mining for a long time. However, the mining activities have damaged the surface vegetation, leading to geological environmental problems such as ground subsidence and groundwater pollution. Even worse, the mining of coal has left a large number of abandoned mines, forming various sizes of pits, which seriously affect the surrounding environment. Therefore, some regions have begun to carry out ecological restoration and reuse of abandoned mines in various ways.

[0003] One of them is the mine pit water body restoration method based on landscape optimization. The mine pit water body restoration system based on landscape optimization is a system that utilizes landscape design principles and ecological restoration technology to restore mine pit water bodies. It changes the landscape environment around the mine pit, provides suitable ecological conditions, and promotes the natural restoration and ecological recovery of the water body.

[0004] For example, a water ecological restoration system is disclosed in Chinese patent CN109607804A. When submerged plants are needed to restore the water in the mine pit, the submerged plants are planted on the pot body, and the insertion slot on the pot body is matched with the pre-set installation position in the planting net body. The insertion slot and the planting net body are inserted and matched, and the pot body is fixed relative to the planting net body by using the fixing member, reducing the separation of the pot body and the planting net body. The number of submerged plants and containers can be set according to needs. The depth of the planting net body in the water body is determined according to the current water transparency, and the floating member is used to move and maintain the planting net body to the corresponding depth range, so that the depth of the planting net body meets the light intensity required for the growth of submerged plants. The planting net body can be kept at a position below the liquid surface and meet the needs of light intensity required for the growth of submerged plants. The submerged plants can successfully restore the water ecological environment in the mine pit and improve the efficiency of water ecological restoration.

[0005] However, the above-mentioned mine pit water body restoration system still has some deficiencies in actual use:

[0006] 1. In the above-mentioned prior art, the submerged plants are planted on the pot body, and then the pot body is placed on the water surface by the support for water resource restoration. This can effectively improve the efficiency of water ecological restoration, but one plant matches one pot body, and the number of pots required is astonishing, which is easy to produce a large amount of cost. Secondly, the existing pot body is generally made of plastic material, which is not only difficult to degrade, but also causes environmental pollution in the whole mine pit.

[0007] 2. In the above-mentioned existing technologies, it is necessary to use plants to treat the water quality of the mine pit. It takes several years or even more than ten years to effectively clean up the pollution sources inside the mine pit. Therefore, the cleaning time is too long. Moreover, during the long-term placement of the mine pit, a large amount of water will accumulate at the bottom of the mine pit after rainy weather. After this water mixes with the water at the bottom of the mine pit, it will further increase the amount of polluted water.

[0008] 3. Secondly, after a certain amount of water accumulates at the bottom of the mine pit, submerged plants will float on the surface of the water. However, the water in the mine pit does not flow and is in a stagnant state. As a result, a large number of bacteria and decaying matter will accumulate in the water after the plants decay, affecting the restoration of the water at the bottom of the mine pit.

[0009] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing mine water remediation systems. Summary of the Invention

DETAILED DESCRIPTION

[0044] The following will be described in detail in conjunction with the accompanying Figures 1-11 The embodiments of the present application are described in detail, but the present application can be implemented in various different ways limited and covered by the claims.

[0045] The embodiments of the present application disclose a mine pit water body repair system based on landscape optimization, and the mine pit A water body repair system is mainly applied in the abandoned mine pit A, mainly repairs the ecological environment of the mine pit A, and mainly repairs the water body of the mine pit through setting various different vegetation, flowers, trees in the mine pit through the ecological system of the vegetation; in the technical effect, the problem of consuming too many raw materials can be avoided in the process of repairing the mine pit A; especially when planting landscape plants, one plant is matched with one pot, because it not only leads to too low plant planting density, but also the operation of planting plants into the pot is complex and a large amount of materials need to be consumed, and the cost is too large.

[0046] Secondly, the mine pit A is generally in a concave bowl-shaped structure, so when the mine pit A is unattended for a long time, a large amount of rainwater will be collected at the bottom of the mine pit A, and after the rainwater contacts the mine pit A for a long time, the rainwater will be polluted by heavy metals; therefore, various different plants are planted in the mine pit A to ensure that the heavy metals in the rainwater and the heavy metals in the mine pit A are purified through the filtering system of the plants.

[0047] Referring to Figure 1 As shown in the figure, a mine pit water body repair system based on landscape optimization includes an isolation trench 1, which is arranged at the slope of the mine pit A at equal intervals, and the circumference of the isolation trench gradually shortens from inside to outside along the slope of the mine pit A.

[0048] The main purpose of the isolation ditches 1 is to divide the mine pit A into several different areas, and each area can be planted with plants that improve soil stability and prevent soil collapse. Secondly, during rainy weather, they can block rainwater and slow down the flow of rainwater to the bottom of the mine pit A. At the same time, if the loose soil around the mine pit A collapses, the isolation ditches 1 can effectively act as a wall to block the collapsing soil and prevent the danger caused by soil collapse.

[0049] See Figure 1 and Figure 2 As shown, the purification module 2 is connected to the isolation ditch 1 and distributed in a ring. The purification module 2 includes a purification pool 20 and an aquatic plant placement rack 21. The purification pool 20 is located on the slope of the mine pit A along the circumferential direction of the mine pit A and is connected to the isolation ditch 1 around the mine pit A. The aquatic plant placement rack 21 is installed in the purification pool 20.

[0050] Several purification pools 20 are evenly spaced on the isolation ditch 1. Through the cooperation of the purification pools 20 and the isolation ditch 1, the water at the bottom of the mine pit A is circulated and flows, preventing the water at the bottom of the mine pit A from not flowing and causing a large number of bacteria to grow inside.

[0051] Furthermore, during the water circulation process within the isolation ditch 1 and the purification pool 20, a large number of different types of plants are planted in the isolation ditch 1 and the purification pool 20 to achieve filtration and purification of the flowing water through the plants.

[0052] Collection module 3 is used to regularly replace and treat the aquatic plants after the water in mine pit A has been repaired. Collection module 3 is located at the bottom of mine pit A.

[0053] When a large number of plants are planted in mine pit A, the plants will absorb water from mine pit A. At the same time, the heavy metals mixed in the water will also be absorbed by the plants and stored in the plants, resulting in a large amount of heavy metals stored in the plants. In order to prevent mine pit A from being re-polluted by heavy metals after these plants die, this invention also proposes a collection module 3, which can periodically collect and clean the plants on the water in mine pit A.

[0057] Firstly, the water pumping pump 40 is started, the water body at the bottom of the pit A is transported into the purification tank 20 at the side through the water pumping pipe 41 by the water pumping pump 40, then the water body enters the isolation ditches 1 along the purification tank 20 at the side, enters other purification tanks 20 through the isolation ditches 1, and finally the purified water body is sprayed on the slope of the pit A by spraying and other ways, so as to perform water supplement operation on the plants planted on the slope of the pit A, and the purified water body can also be arranged in some landscape, such as waterfall, so as to improve the richness of the beautification of the pit A.

[0058] It should be noted that the power required by the water pumping pump 40 can be ensured by solar power generation to realize self-sufficiency of the pit A, or can be provided by the power grid.

[0059] Referring to Figure 3 and Figure 4 As shown in the structure diagram of purifying the pit A in the embodiment; the purification module 2 further comprises a purification net 22, a purification frame 23, a purification box 24 and an environmental protection film 25; the water inlet and the water outlet are respectively arranged at the two ends of the purification tank 20, the purification net 22 is arranged at the water inlet and the water outlet of the purification tank 20, the purification frame 23 is clamped and installed at the upper end of the isolation ditch 1, the purification box 24 is arranged at the bottom of the purification frame 23, and the inside of the purification box 24 is filled with adsorbed activated carbon.

[0060] The upper end of the purification frame 23 is provided with small holes at equal intervals, the environmental protection film 25 is arranged in the small holes, and the environmental protection film 25 is recessed inward close to the small holes of the purification frame 23; the purpose is to ensure that the seeds of plants and the seedlings of plants can be quickly settled, when the plants grow, the plants can be pierced through the environmental protection film 25 by the tough root system and penetrated into the water body through the small holes on the purification frame 23 by the characteristics of the plants themselves, and the water body is gradually rich in the interlaced roots, so as to facilitate the repair and filtration of the water body.

[0061] When the water body reciprocating flow along the isolation ditch 1 and purification tank 20, can be planted on the purification frame 23 seed, then the seed on the purification frame 23 on the environmental protection film 25 independent germination, and make it grow, finally the plant root in the process of growth by itself to break environmental protection film 25, down to touch the water in the purification tank 20, it can not only purify the water in the purification tank 20 water flow, but also filter the impurities mixed in the water.

[0062] Second, the isolation ditch 1 is provided with the same environmental protection film 25, ensure the growth of plants.

[0063] When the purification tank 20 in the plant growth, can be taken out, planting to other parts of the mine A, realize the whole mine A plant coverage, greatly guarantee the stability of the whole mine A, until the whole mine A ecological environment is repaired.

[0064] In order to further improve the purification efficiency of water in the purification tank 20, the bottom of the purification tank 20 on the purification frame 23 is provided with purification box 24, and the purification box 24 is provided with activated carbon adsorption, which can filter the water in the flow process.

[0065] With the cooperation of activated carbon and plants, the water in the mine A can be repaired in a certain time.

[0066] Referring to Figure 5 and Figure 6 When the water in the mine A is repaired by the plant through ecological restoration, the plant on the water will absorb a large amount of heavy metal, resulting in the storage of certain harmful substances in the plant. If these plants are not treated regularly, the plants will dry up in place, resulting in the reentry of heavy metals and other harmful substances absorbed by the plants into the soil of the mine A, and finally into the water brought by the rain, and into the water at the bottom of the mine A, resulting in secondary pollution of the water. Therefore, the plants need to be cleaned after a certain period of planting. Therefore, the collecting module 3 is provided in the embodiment.

[0067] The collecting module 3 comprises a driving control shaft 30 connected to the bottom of the pit A, a plurality of horizontal plates 31 are slidably installed on the driving control shaft 30 at equal intervals in the circumferential direction, a sliding groove is formed on the driving control shaft 30 for the installation of the horizontal plates 31, a reset compression spring 32 is fixedly connected between the horizontal plate 31 and the driving control shaft 30, so that the horizontal plate 31 can reciprocate up and down along the driving control shaft 30, a plurality of pairs of collecting frames 33 are fixedly installed on the horizontal plate 31 at equal intervals, the openings of the collecting frames 33 are upwardly distributed, so as to facilitate the collection and treatment of impurities floating on the water at the bottom of the pit A, a blocking mesh plate 34 is also fixedly installed inside the collecting frame 33, the bottom of the blocking mesh plate 34 is sleeved with a mesh cloth 35.

[0068] The bottom of the pit A is provided with the driving control shaft 30 through the base, and the driving control shaft 30 rotates, and the horizontal plate 31 capable of reciprocating up and down is arranged on the driving control shaft 30, when the driving control shaft 30 rotates, the horizontal plate 31 can reciprocate up and down under the action of the driving module 5, the upper end of the horizontal plate 31 is fixedly connected with the collecting frame 33, when the horizontal plate 31 moves upward, the collecting frame 33 can collect the floating impurities on the water surface into the inside, and in the process, the blocking mesh plate 34 and the mesh cloth 35 are fixedly installed inside the collecting frame 33, which can ensure that the floating impurities and some dry and rotten plants are collected by the collecting frame 33, and when these impurities enter the collecting frame 33, they will not flow out of the collecting frame 33 with the water flow, the mesh cloth 35 and the blocking mesh plate 34 can effectively improve the efficiency of the collecting frame 33 in collecting impurities, when the collecting frame 33 collects a certain amount of impurities, the collecting frame 33 can be disassembled, and the impurities in the collecting frame 33 can be disposed of.

[0069] As shown in FIGS. Figure 5 , Figure 6 and Figure 8 , it is a structure diagram of driving the driving control shaft 30 to rotate in the embodiment, the bottom of the driving control shaft 30 is also provided with the driving module 5, the driving module 5 comprises a wave ring 50, a reciprocating push rod 51 and a driving motor 52, the wave ring 50 is fixedly installed at the bottom of the pit A, and the wave ring 50 is sleeved on the outer side of the driving control shaft 30, the bottom of the horizontal plate 31 is fixedly connected with the reciprocating push rod 51, one end of the reciprocating push rod 51 away from the horizontal plate 31 abuts against the upper end of the wave ring 50, the driving motor 52 is connected with the driving control shaft 30, and the driving motor 52 is arranged in a waterproof frame arranged at the bottom of the pit A through a motor base.

[0070] In the implementation process, the driving motor 52 drives the main control shaft 30 to rotate, and then the main control shaft 30 drives the external several horizontal plates 31 to rotate at a constant speed. In the process of rotating the horizontal plate 31, the reciprocating push rod 51 at the bottom abuts against the top end of the wave ring 50, and the top end of the wave ring 50 is in a concave-convex wave structure. Therefore, in the process of rotating the main control shaft 30, the reciprocating push rod 51 realizes the up-down reciprocating swing of the horizontal plate 31.

[0071] Referring to Figure 7 and Figure 9 As shown in the figure, the side wall of the wave ring 50 is fixedly installed with several fixed plates 6, and the fixed plates 6 and the isolation trench 1 are both provided with a water spraying assembly 60. The water spraying assembly 60 includes a vertical sleeve 600, an injection plug 601, a pressing rod 602, a pressing tension spring 603, a water suction hole 604, and a spray head 605. The vertical sleeve 600 is installed on the outer wall of the fixed plate 6 and the isolation trench 1. The injection plug 601 is slidingly installed in the vertical sleeve 600.

The pressing tension spring 603 is sleeved on the pressing rod 602. One end of the pressing tension spring 603 is arranged at the upper end of the vertical sleeve 600, and the other end is arranged at the end of the pressing rod 602 away from the vertical sleeve 600.

[0072] The bottom of the vertical sleeve 600 on the fixed plate 6 is fixedly connected with the spray head 605. The side wall of the vertical sleeve 600 on the fixed plate 6 is provided with the water suction hole 604.

[0073] In the implementation process, the vertical sleeves 600 are arranged on the fixed plate 6 and the isolation trench 1. However, the positions and angles of the two vertical sleeves 600 are different. The water outlet of the vertical sleeve 600 on the fixed plate 6 faces downward, and the vertical sleeve 600 on the isolation trench 1 is horizontally distributed along the direction of the slope of the mine pit A.

[0074] When the press bar 602 drives the injection plug 601 to move away from the vertical sleeve 600, the water in the pit A can be absorbed into the vertical sleeve 600 through the water suction hole 604 on the vertical sleeve 600. Then, when the injection plug 601 moves towards the vertical sleeve 600, the water in the vertical sleeve 600 will be sprayed out of the nozzle 605 after the injection plug 601 passes the water suction hole 604. After the water at the bottom of the pit A is sprayed out, it can be sprayed outwards to form a fountain. At this time, under the irradiation of the external sun, the toxic substances mixed in the water can be purified, and the sprayed water forms a fountain, which can form a landscape and enrich the landscape richness of the entire pit A.

[0076] The purpose of the entire linkage traction rope 70 is to ensure that the press bar 602 on the fixed plate 6 and the press bar 602 on the isolation trench 1 can be linked to realize the alternate water spraying of the vertical sleeve 600 on the fixed plate 6 and the vertical sleeve 600 on the isolation trench 1.

[0077] Referring to Figure 11 As shown, it is a flow chart of the pit water body repair process; when working: first, the water at the bottom of the pit A is drawn into the isolation trench 1 through the water suction pipe 41, and then the water is drawn into the purification tank 20 through the isolation trench 1, so as to realize the circulating flow of the water at the bottom of the pit A, avoid the water at the bottom of the pit A in a static state for a long time, and cause the water to breed bacteria.
