Description

Technical Field

[0001] This utility model belongs to the field of water storage devices, and in particular relates to a water storage device for mine ecological restoration. Background Technology

[0002] Currently, the main method for ecological restoration of revegetable areas in mining areas, such as mine end steps, industrial squares, and crushing platforms, involves covering the end steps with soil, planting trees, shrubs, grasses, and climbing vines, and then maintaining the vegetation. The natural growth of the plants covers the exposed soil and rock, achieving a revegetation effect. However, at present, many mine ecological restoration projects fail due to poor vegetation management and the harsh natural environment and water scarcity in the mines. The soil becomes waterlogged, cracks, and the plants die, directly leading to the failure of the ecological restoration. Therefore, to ensure the successful implementation of ecological restoration projects in revegetable areas of mines, artificial watering is necessary in the early stages of vegetation restoration. This requires the installation of necessary water supply facilities, among which water storage devices are a crucial component.

[0003] Existing water storage devices mainly consist of waterwheels or water tanks. Waterwheels are more commonly used in areas with poor conditions and have significant limitations. Water tanks, on the other hand, rely on water supply pipelines to obtain water and cannot utilize the water source from the mine's drainage and flood discharge system. This results in a heavy dependence on municipal water supply or reservoir water supply and also leads to the waste of water resources. Utility Model Content

[0004] The purpose of this invention is to provide a water storage device for mine ecological restoration, which has dual water source supply guarantee and improves the efficiency of water resource utilization.

[0005] The aforementioned water storage device for mine ecological restoration includes a water storage tank with a water supply pipe. A filter box is installed above the water storage tank, and a filter assembly for multi-stage filtration of rainwater and automatic cleaning of impurities is installed inside the filter box. An inlet pipe for introducing filtered rainwater into the water storage tank is installed on the top of the water storage tank. A T-junction is installed on one side of the water storage tank. One end of the T-junction is connected to a water intake assembly for introducing water from the water storage tank into the T-junction. The other two ends of the T-junction are respectively connected to a first drain pipe and a second drain pipe. Valves are installed on both the first drain pipe and the second drain pipe.

[0006] Furthermore, the water filter box has a structure that is higher on the left and lower on the right. The top left side of the water filter box has an inlet groove for rainwater to enter the water filter box, and the right side wall at the bottom of the water filter box has an outlet groove for filtered rainwater to flow out.

[0007] Furthermore, the filter assembly includes a first filter screen, a second filter screen, and a third filter screen that are distributed vertically and whose filtration accuracy and length increase sequentially. The first filter screen, the second filter screen, and the third filter screen are all fixed to the left inner side wall of the water filter tank with a left-high and right-low tilt, and the right end of the third filter screen is fixed to the right inner side wall of the water filter tank.

[0008] Furthermore, one end of the water inlet pipe is fixed inside the water outlet trough of the water filter tank, and the other end is located inside the upper end of the water storage tank.

[0009] Furthermore, the upper right side wall of the water filter box is provided with a channel for removing impurities filtered out from the rainwater inside the water filter box.

[0010] Furthermore, a cleaning plate for temporarily placing impurities filtered out from rainwater is fixed to the right side wall of the water filter tank.

[0011] Furthermore, the water intake assembly includes a water pump, with an outlet pipe connected to the inlet end of the water pump. The other end of the outlet pipe is located inside the lower end of the water storage tank, and the outlet pipe of the water pump is connected to one of the ports of a three-way pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a first, second, and third filter screen to perform three-stage filtration of rainwater containing impurities entering the filter tank. After filtration, the rainwater flows into a storage tank through an outlet channel on the right side wall of the filter tank. This allows rainwater from the mine to be stored for subsequent irrigation of vegetation, providing a dual water source guarantee for mine vegetation irrigation and effectively improving the utilization efficiency of natural precipitation resources. Furthermore, the filtration precision and length of the first, second, and third filter screens increase sequentially. The first, second, and third filters are all fixed to the left inner wall of the filter tank with a left-high, right-low tilt. Therefore, impurities of various sizes will be collected at the right end of the third filter under the action of water flow and gravity, and can be removed by workers from the through groove on the right side wall of the filter tank. This utility model also uses the first and second drain pipes with valves to irrigate the vegetation around the location of the water storage tank, and to pump the water resources in the water storage tank to higher altitude areas in the mine, thus achieving the effect of multi-stage water supply.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0018] This embodiment describes a water storage device for mine ecological restoration, including a water storage tank 7 with a water supply pipe, such as... Figure 1 As shown, a water supply pipe is installed on top of the water storage tank 7. This water supply pipe is used to temporarily store municipal water or reservoir water into the water storage tank 7.

[0019] A water filter tank 1 is installed above the water storage tank 7, such as... Figure 1 As shown, the water filter box 1 has a structure that is higher on the left and lower on the right. The top left of the water filter box 1 has an inlet groove for rainwater to enter the water filter box 1, and the right side wall at the bottom of the water filter box 1 has an outlet groove for filtered rainwater to flow out. Since the water filter box 1 has a structure that is higher on the left and lower on the right, rainwater enters from the inlet groove at the top left of the water filter box 1, is filtered, and then flows out from the outlet groove on the right side wall of the water filter box 1.

[0020] refer to Figure 1 and Figure 2The water filter tank 1 is equipped with a first filter screen 2, a second filter screen 3, and a third filter screen 4 arranged vertically with increasing filtration precision and length. The first filter screen 2, the second filter screen 3, and the third filter screen 4 are all fixed to the left inner wall of the water filter tank 1 with a left-high, right-low tilt, and the right end of the third filter screen 4 is fixed to the right inner wall of the water filter tank 1. (The first filter screen 2, the second filter screen 3, and the third filter screen 4 together constitute the filter assembly used for multi-stage filtration of rainwater and automatic cleaning of impurities. The length of the first filter screen 2 can be the same as the length of the second filter screen 3, but both are shorter than the length of the third filter screen 4.) In this embodiment, the first filter screen 2, the second filter screen 3, and the third filter screen 4 can perform three-stage filtration of rainwater containing impurities entering the water filter tank 1, preventing dead branches and leaves from entering the water storage tank 7, while also... The filtration precision and length of the first filter screen 2, the second filter screen 3, and the third filter screen 4 increase sequentially. Since the first filter screen 2, the second filter screen 3, and the third filter screen 4 are all fixed to the left inner wall of the water filter tank 1 with a left-high, right-low tilt, impurities of various sizes will collect at the right end of the third filter screen 4 under the action of water flow and gravity. The first filter screen 2 has a pore size of 5-10mm, uses stainless steel mesh or high-density polyethylene mesh, and is mainly used to intercept large floating objects or debris such as leaves, branches, and plastic bags. The second filter screen 3 has a pore size of 1-3mm, uses stainless steel wire mesh or nylon filter cloth, and is mainly used to intercept large suspended particles such as sand and gravel. The third filter screen 4 has a pore size of 0.1-0.5mm, uses polyester fiber filter cloth or ceramic filter screen, and is mainly used to intercept small particulate impurities such as fine sand and silt.

[0021] The top of the water storage tank 7 is equipped with an inlet pipe 6 for guiding filtered rainwater into the tank. The filtered rainwater flows out from the outlet trough and into the water storage tank 7 along the inlet pipe 6. This allows rainwater in the mine to be stored for later use in irrigating the mine's vegetation, thus providing a dual water source guarantee for irrigation and effectively improving the utilization efficiency of natural precipitation resources. Figure 1 and Figure 2 As shown, one end of the inlet pipe 6 is fixed in the outlet trough of the filter tank 1, and the other end is located in the upper part of the storage tank 7.

[0022] like Figure 1 As shown, a channel is provided on the right side wall at the upper end of the water filter box 1 for removing impurities filtered from rainwater inside the water filter box 1. Workers can use this channel to remove dead branches, fallen leaves, sand particles, etc. that have gathered at the right end of the third filter screen 4 from the water filter box 1.

[0023] refer to Figure 1A three-way pipe 12 is provided on one side of the water storage tank 7, and a water pump 13 is provided on the other side of the water storage tank 7. One of the pipe ports of the three-way pipe 12 is connected to and communicates with the water outlet of the water pump 13. The water inlet of the water pump 13 is connected to a section of the water outlet pipe 8, and the other end of the water outlet pipe 8 is located inside the lower end of the water storage tank 7. (The water pump 13 and the water outlet pipe 8 in this section constitute the water intake component used to introduce water from the water storage tank 7 into the three-way pipe 12. In actual application, the water pump 13 can also be a submersible pump and placed inside the water storage tank 7.) In this embodiment, the water resources in the water storage tank 7 can be extracted for use when it is necessary to irrigate the mine vegetation through the water pump 13 and the water outlet pipe 8.

[0024] The other two ports of the tee pipe 12 are connected to the first drain pipe 9 and the second drain pipe 11, respectively. Valves 10 are installed on both the first drain pipe 9 and the second drain pipe 11. Figure 1 As shown, in this embodiment, the first drain pipe 9 and the second drain pipe 11 with valve 10 can irrigate the vegetation around the location of the water storage tank 7, and can also pump the water resources in the water storage tank 7 to areas at higher altitudes in the mine, thus achieving the effect of multi-level water supply.

[0025] In this embodiment, rainwater from the intercepting ditch, collecting ditch, rapid flow channel, and drainage ditch is first diverted through pipes to the inlet of the filter tank 1, allowing the rainwater containing impurities to flow into the filter tank 1. Then, the rainwater passes through the first filter screen 2, the second filter screen 3, and the third filter screen 4, where dead leaves, large particles of sand, and small particles of sand are filtered out, respectively. Since the first filter screen 2, the second filter screen 3, and the third filter screen 4 are all fixed to the left inner wall of the filter tank 1 with a left-high, right-low tilt, impurities of various sizes will collect at the right end of the third filter screen 4 under the action of water flow and gravity. At this point, the operator can then remove the impurities from the filter tank. The channel on the right side wall cleans the filtered impurities from the water filter tank 1, while the filtered rainwater flows out from the outlet channel and into the water storage tank 7 along the inlet pipe 6. When it is necessary to irrigate the vegetation in the mine, the staff opens the corresponding water pump 13 and the valve 10 on the second drain pipe 11 according to the location of the water storage tank 7, and then the vegetation can be irrigated. Finally, if the water resources in the water storage tank 7 in the higher altitude area of ​​the mine are relatively scarce, the water pump 13 in the lower altitude area and the valve 10 on the first drain pipe 9 are opened to pump the water in the water storage tank 7 in the lower altitude area to the water storage tank 7 in the higher altitude area for irrigation of the vegetation. Example

[0026] This embodiment further illustrates the technology. The right side wall of the filter tank 1 is fixed with a cleaning plate 5 for temporarily holding impurities filtered from rainwater. Figure 1 As shown, the cleaning plate 5 is used to temporarily place dead branches, leaves, sand and gravel particles filtered out from the rainwater, which can further facilitate the staff to clean these impurities.
