Description

Technical Field

[0001] The invention relates to the technical field of tailings pond restoration, and in particular to a tailings pond land restoration device. Background Art

[0002] With the mining of the mining area, land resources will be destroyed. At the same time, after the mineral processing, a large amount of abandoned land such as tailings ponds will be generated. Since the land of the tailings pond is barren and the ecological degradation is serious, it is easy to cause ecological and environmental problems. Therefore, it is necessary to repair the land of the tailings pond to avoid soil erosion. The existing repair of the tailings pond is mainly through covering with foreign soil, and combined with bacteria, vegetation and other means for repair. However, for the slope of the tailings pond, due to the large slope of this location, after the foreign soil is covered, it is easy to be washed away before the vegetation grows, resulting in soil erosion. The survival rate of vegetation is low, making this location difficult to repair. For this reason, people have designed a variety of repair devices. For example, the Chinese patent with application number 202223227548.9 discloses a mine ecological restoration device, including a mine, the slope of the mine is provided with evenly distributed planting troughs, the slope of the mine is provided with a protective slope, and the protective slope is provided with evenly distributed rectangular through grooves. Through the setting of the protective slope, the protective slope is provided with evenly distributed rectangular through grooves, and the through grooves are connected to the planting The troughs are interconnected, where the planting troughs are used for planting green vegetation, and are connected to the rectangular frame at the protective slope through connecting rods, and the side ends of the rectangular frame are connected to the sprinkler through connecting pipes, where nutrient solution is sprayed on the green vegetation through the sprinkler, thereby watering and fertilizing the green vegetation, thereby ensuring the good survival of the vegetation, thereby achieving the greening and restoration effect on the ecological environment of the mine. However, in actual use, since the irrigation system of the structure is relatively complicated and easily blocked, and the tailings pond is usually far away from the urban area, it is difficult to maintain in the later stage. Therefore, a tailings pond land restoration device is needed, which can effectively maintain the moisture of the plants on the slope of the tailings pond, and the irrigation structure is simple and effective, not easy to be blocked, reliable, and easy to maintain.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] like Figures 1 to 4 As shown, an embodiment of the present invention provides a tailings pond land restoration device, including: a tailings pond slope 1, a slope protection board 2, a water storage tank 3, and a water storage pool 4. The slope protection board 2 is set on the tailings pond slope 1 by casting, and the slope protection boards 2 form square vegetation troughs 5 with each other; a mounting hole is opened on the tailings pond slope 1, and the water storage tank 3 is buried in the mounting hole along the tailings pond slope 1, and an opening is provided on the upper part of the water storage tank 3; the water storage pool 4 is installed at the bottom of the tailings pond slope 1, and the water inlet of the water storage pool 4 is set at the lower edge of the vegetation trough 5.

[0028] When repairing the tailings pond slope, first dig a trench, and then use a template to cast a slope protection board 2 on the tailings pond slope 1. The slope protection board 2 divides the tailings pond slope 1 into multiple vegetation troughs 5, which can stabilize the tailings pond slope 1 and reduce the erosion of rainwater on the tailings pond slope 1. When pouring the slope protection board 2, it is also necessary to drive multiple soil nails into the tailings pond slope 1, and then pour the soil nails together with the steel bars of the slope protection board 2 to increase the connection strength between the slope protection board 2 and the tailings pond slope 1. After the slope protection board 2 is set, an installation hole is opened on the tailings pond slope 1, and a water storage tank 3 is placed in the installation hole. After a cloth strip 9 is placed in the water storage tank 3, a guest soil layer 6 is laid in the vegetation trough 5. After sowing vegetation seeds in the guest soil layer 6, a non-woven fabric layer 7 is laid on the guest soil layer 6, and the four corners of the non-woven fabric layer 7 are nailed into the tailings pond slope 1 by nails. The non-woven fabric layer 7 can reduce the scouring of the guest soil layer 6 by rainwater, and can absorb part of the water through the non-woven fabric layer 7 to accelerate the germination of seeds. Before the vegetation grows, the non-woven fabric layer 7 protects the guest soil layer 6, and after the vegetation grows, the non-woven fabric layer 7 naturally degrades, so as not to affect the growth of plants. When it rains, the excess rainwater seeps through the guest soil layer 6 and is collected in the water storage tank 3. Then, through the capillary action of the cloth strip 9, the water in the water storage tank 3 moistens the vegetation trough 5 to provide water for the growth of plants. After the rain, the excess rainwater also collects at the bottom of the tailings pond slope 1 and flows into the water storage tank 4 for use by plants when the rainfall is insufficient.

[0029] When rainfall is insufficient, the battery 13 drives the water pump 14 to replenish the water in the water storage pool 4 into each water storage tank 3 to ensure that the plants have sufficient water. At the same time, nutrient solution can be added to the water storage pool 4 to provide nutrients required for plant growth, so that the plants can grow rapidly on the barren tailings pond. After the plants grow, their roots will penetrate into the guest soil layer 6 and the tailings pond slope 1, thereby resisting the erosion of the tailings pond slope 1 by rainwater, avoiding landslides of the tailings pond slope 1, and repairing the ecology of the tailings pond slope 1.

[0030] Preferably, the vegetation trough 5 is covered with a guest soil layer 6, the upper part of the guest soil layer 6 is covered with a non-woven fabric layer 7, and vegetation is planted in the guest soil layer 6. Since the land of the tailings pond is relatively poor in the early stage and is not conducive to the growth of plants, it is necessary to cover the guest soil layer 6 and use bacterial species to improve the soil, continuously improve the fertility of the tailings pond land, and maintain the water and soil of the tailings pond through plants. After a certain period of improvement, the soil of the tailings pond land is suitable for the growth of other plants, thereby achieving ecological restoration. The non-woven fabric layer 7 can reduce rainwater erosion and water evaporation in the early stage of plant growth, thereby improving the survival rate of plant seeds. The non-woven fabric layer 7 is supported by degradable materials and will naturally degrade under the action of ultraviolet rays. At this time, the plant root system has also been developed, so it mainly relies on plants to maintain the water and soil of the tailings pond slope 1.

[0031] Specifically, a cover plate 8 is provided at the opening of the water storage tank 3, and a plurality of water-permeable holes are provided on the cover plate 8. The cover plate 8 can prevent the foreign soil layer 6 from falling into the water storage tank 3. The water storage tank 3 can store part of the rainwater and slowly release it during drought to provide the required moisture for the plants.

[0032] In a specific embodiment, a cloth strip 9 is provided on the cover plate 8, one end of the cloth strip 9 is buried in the guest soil layer 6, and the other end of the cloth strip 9 extends to the bottom of the water storage tank 3 after passing through the cover plate 8. The cloth strip 9 can use capillary action to allow moisture to penetrate from the water storage tank 3 into the guest soil layer 6, thereby providing the required moisture for the plants.

[0033] Preferably, if Figure 2 As shown, there are multiple water storage tanks 3 in the vegetation trough 5 to improve the water storage capacity and ensure that the plants still have enough water during precipitation. When there is a lot of rain, the rainwater will gather at the bottom of the vegetation trough 5 and then flow into the lowest water storage tank 3. The upper edge of the water storage tank 3 in the lower part of the vegetation trough 5 is flush with the upper edge of the slope protection plate 2 at the bottom of the vegetation trough 5, which can ensure that the water in the water storage tank 3 will overflow to the next vegetation trough 5 only after it is full.

[0034] In a preferred embodiment, Figure 3As shown, a sinking trough 10 is provided at the water inlet of the water storage pool 4. The side of the sinking trough 10 is connected to the inner cavity of the water storage pool 4 through a through hole, and a filter screen 11 is provided on the side of the through hole. The sinking trough 10 and the filter screen 11 can reduce the amount of sand and stones falling into the water storage pool 4 and extend the dredging cycle of the water storage pool 4.

[0035] In a preferred embodiment, it also includes a solar panel 12, a battery 13, and a water pump 14. The solar panel 12 is installed on the ground, and the solar panel 12 is connected to the battery 13 through a controller. The water inlet of the water pump 14 is connected to the bottom of the water storage pool 4, and the water outlet of the water pump 14 is connected to the inner cavity of each water storage tank 3 through a pipeline. Photovoltaic power is provided to the water pump 14, so that water in the water storage pool 4 can be pumped into each water storage tank 3 during drought to ensure the growth of plants.

[0036] In a preferred embodiment, Figure 4 As shown, a condenser 15 is provided on the upper part of the water storage tank 4, and the bottom of the condenser 15 is connected to the inner cavity of the water storage tank 4 through a pipe. The condenser 15 is connected to the battery 13. When there is less precipitation and the air humidity is relatively high at night, the condenser 15 can be used to condense the water vapor in the air into small droplets according to the principle of condensation and collect them in the water storage tank 4. At the same time, when there is a lack of water, a water shortage signal can be remotely sent to the server through the controller, so that the staff can use a water truck to replenish the water storage tank 4 with water.

[0037] In a preferred embodiment, a semiconductor refrigeration sheet 16, a condensation plate 17, and a first fan 18 are provided in the condenser 15. The cold end of the semiconductor refrigeration sheet 16 is symmetrically installed in the condenser 15. The condensation plate 17 is installed in parallel between the semiconductor refrigeration sheets 16, and the condensation plate 17 is connected to the semiconductor refrigeration sheet 16 through a heat pipe 19. The first fan 18 is installed on the upper part of the condenser 15. The semiconductor refrigeration sheet 16 adopts an existing semiconductor refrigeration sheet. After power is turned on, the temperature on one side of the semiconductor refrigeration sheet 16 drops, and the temperature on the other side rises. The hot end is cooled by the heat sink and the heat dissipation fan 20, and the cold end is connected to the condensation plate 17 through the heat pipe 19, so that after the temperature of the condensation plate 17 is reduced, the air is blown through the condensation plates 17 by the first fan 18, so that the water vapor in the air is cooled and condensed on the condensation plates 17, and then gathered into droplets and flow into the water storage pool 4, and a part of the water is added to the water storage pool 4 when there is little precipitation.

[0038] In a preferred embodiment, a heat sink is provided at the hot end of the semiconductor refrigeration chip 16, and a cooling fan 20 is provided on the heat sink. The heat generated at the hot end of the semiconductor refrigeration chip 16 is diffused into the atmosphere through the heat sink and the cooling fan 20, thereby achieving continuous cooling of the semiconductor refrigeration chip 16.

[0039] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
