Description

Technical Field

[0001] This invention belongs to the field of mine restoration technology, and more specifically, relates to a lawn water-saving system for mine restoration. Background Technology

[0002] Mining activities can easily cause ecological problems such as soil erosion, desertification, and heavy metal pollution. In order to avoid the impact on the ecological environment around the mine, it is necessary to use turf vegetation to stabilize the soil and conserve water and improve the soil microenvironment, so that the mining area ecosystem can be restored.

[0003] When restoring a mine, soil needs to be backfilled into the restoration area, and then turf is planted on the backfilled soil. Because the backfilled soil has high porosity, when it rains or irrigates, the water will quickly seep into the backfilled soil. This phenomenon makes it difficult for water to be effectively retained in the surface layer where the turf roots are distributed, resulting in low water resource utilization efficiency. Summary of the Invention

[0004] To address the problem of water rapidly seeping down from the backfill soil, this invention proposes a lawn water-saving system for mine restoration, overcoming the aforementioned technical problems of existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention is a lawn water-saving system for mine restoration, comprising a support plate, a restoration layer on the top of the support plate, a water storage tank at the bottom of the support plate, a collection component between the water storage tank and the restoration layer, a separation component inside the water storage tank, an irrigation component on the top of the restoration layer, and a connection end of the irrigation component connected to the bottom of the water storage tank.

[0007] The water storage tank collects the water that seeps down from the repair layer through the collection component. The separation component is used to separate the collected water into solid and liquid components. The connection end of the irrigation component is used to extract the separated water so that the irrigation end can irrigate the repair layer.

[0008] Furthermore, the repair layer includes a vibration isolation layer, which is disposed on top of the support plate. A pad is disposed on top of the vibration isolation layer, and a grass layer is disposed on top of the pad.

[0009] Further, the collecting assembly comprises a tapered groove, which is arranged on the top of the cushion plate, a collecting hole is arranged at the bottom of the tapered groove, the collecting hole penetrates the shock insulation layer and the supporting plate, a collecting pipe is fixedly installed at the bottom of the supporting plate and corresponds to the collecting hole, a converging pipe is fixedly connected to the outer surface of the collecting pipe, one end of the converging pipe is fixedly installed on the top of the water storage tank, and an electric valve is fixedly installed on the outer surface of the collecting pipe.

[0010] Further, the separating assembly comprises a converging hopper, which is fixedly installed on the inner wall of the water storage tank, a feeding pipe is fixedly connected to one side of the water storage tank, the feeding pipe is arranged on the upper side of the converging hopper, a discharging pipe is fixedly connected to the bottom of the converging hopper, and one end of the discharging pipe extends to the outside of the water storage tank.

[0011] Further, the water storage tank is fixedly installed with a pumping pipe, one end of the pumping pipe extends to the inside of the water storage tank, the other end of the pumping pipe is fixedly connected to the front face of the water storage tank, a pumping pump is fixedly installed on the front face of the water storage tank, the pumping pump is connected to the pumping pipe, a lifting pipe is arranged in the pumping pipe, a float is arranged on the outer surface of the lifting pipe, a rubber pad is arranged on the outer surface of the lifting pipe, and the rubber pad is attached to the pumping pipe.

[0012] Further, the water storage tank is fixedly installed with a receiving pipe, a T-shaped guide rod is movably connected in the receiving pipe, the T-shaped guide rod penetrates the water storage tank and is fixedly connected to the float, and springs are fixedly connected between the outer protruding positions of the T-shaped guide rod and the inner walls of the receiving pipe.

[0013] Further, the irrigation assembly comprises an installation cylinder, which penetrates the supporting plate, the shock insulation layer, the cushion plate and the lawn layer, an irrigation pipe is arranged in the installation cylinder, a spray head is fixedly installed at the top end of the irrigation pipe, an irrigation water pump is fixedly connected to the back face of the water storage tank, the bottom end of the irrigation pipe is connected to the irrigation water pump, a connecting pipe is fixedly connected to the bottom of the water storage tank and connected to the irrigation water pump, and a pressure regulating valve is arranged on the outer surface of the connecting pipe.

[0014] Further, the bottom of the supporting plate is fixedly connected with a supporting frame.

[0015] The present application has the following advantages:

[0016] 1. This invention uses a support plate to block moisture inside the repair layer, ensuring that water remains inside the repair layer during irrigation. When it rains, the collection component can be opened, allowing the water tank to collect the seeping water. Simultaneously, the irrigation component allows the collected rainwater to be used for subsequent irrigation of the repair layer. In summary, this design, which blocks and collects moisture inside the repair layer, significantly improves water resource utilization efficiency during mine restoration.

[0017] 2. This invention uses a spring to pull the T-shaped guide rod downwards, so that the float can always stay on the water surface under the push of the T-shaped guide rod and the buoyancy. This setting allows the float to move downwards normally with the water level when the water level drops. At the same time, with the support of the float, the bottom of the lifting pipe can always be slightly lower than the water surface. This setting allows the lifting pipe to always draw the upper layer of clean water when extracting clean water, effectively preventing the lifting pipe from sucking in the bottom sewage containing solid impurities.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0029] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0030] Please see Figures 1-6 As shown, the present invention is a lawn water-saving system for mine restoration, including a support plate 1, a restoration layer 2 on the top of the support plate 1, a water storage tank 3 at the bottom of the support plate 1, a collection component 4 between the water storage tank 3 and the restoration layer 2, a separation component 5 inside the water storage tank 3, an irrigation component 6 on the top of the restoration layer 2, and the connection end of the irrigation component 6 is connected to the bottom of the water storage tank 3.

[0031] The water storage tank 3 collects the water that seeps down from the repair layer 2 through the collection component 4. The separation component 5 is used to separate the collected water into solid and liquid components. The connection end of the irrigation component 6 is used to extract the separated water so that the irrigation end can irrigate the repair layer 2.

[0032] When it rains, the collection component 4 opens, allowing the water inside the repair layer 2 to seep downwards and flow through the collection component 4 into the water storage tank 3. When it stops raining, the collection component 4 closes. At this time, the separation component 5 inside the water storage tank 3 can perform solid-liquid separation on the collected rainwater. When the water level inside the water storage tank 3 reaches a predetermined threshold, the connection end of the irrigation component 6 can extract the separated clean water, allowing the irrigation end to irrigate the repair layer 2. When the clean water level inside the water storage tank 3 falls below the predetermined threshold, the irrigation component 6 stops working.

[0033] The support plate 1 can block moisture inside the repair layer 2, ensuring that the moisture remains inside the repair layer 2 during irrigation. When it rains, the collection component 4 can be opened, allowing the water storage tank 3 to collect the seeping water. The collected rainwater can then be used for subsequent irrigation of the repair layer 2 via the irrigation component 6. In summary, the design that blocks and collects moisture inside the repair layer 2 significantly improves water resource utilization efficiency during mine restoration.

[0034] In one embodiment, for the aforementioned vibration isolation layer 201, the repair layer 2 includes the vibration isolation layer 201, the vibration isolation layer 201 is disposed on the top of the support plate 1, the top of the vibration isolation layer 201 is provided with a pad plate 202, and the top of the pad plate 202 is provided with a lawn layer 203.

[0035] The isolation layer 201 is composed of gravel, which allows the isolation layer 201 to buffer the force transmitted from the lawn layer 203, and also ensures the support effect of the support plate 1; the pad plate 202 can separate the isolation layer 201 from the lawn layer 203, so that the soil on the lawn layer 203 is not easy to seep into the interior of the isolation layer 201; the pad plate 202 is made of high-density polyethylene, which gives the pad plate 202 a certain strength and durability.

[0036] In one embodiment, for the above-mentioned collection component 4 package, the collection component 4 includes a conical groove 401, which is formed on the top of the pad 202. The bottom of the conical groove 401 has a collection hole 402, which penetrates the vibration isolation layer 201 and the support plate 1. A collection pipe 403 is fixedly installed on the bottom of the support plate 1 corresponding to the collection hole 402. An inlet pipe 404 is fixedly connected to the outer surface of the collection pipe 403. One end of the inlet pipe 404 is fixedly installed on the top of the water storage tank 3. An electric valve 405 is fixedly installed on the outer surface of the collection pipe 403.

[0037] Multiple support plates 1 can be set, and a single support plate 1 is set on the upper side. Multiple support plates 1 share a water storage tank 3. The modular design of the support plates 1 makes it convenient to install them on the mine. The collection hole 402 can be formed by passing a steel pipe through the vibration isolation layer 201 and the support plate 1. The electric valve 405 will only open when it rains. This design ensures that when the lawn layer 203 is irrigated normally, water will not fall into the water storage tank 3 through the collection pipe 403. In addition, the filter screen set at the collection hole 402 makes it difficult for the soil on the lawn layer 203 to flow into the collection pipe 403 with the water.

[0038] When it rains, the optical rain sensor can control all the electric valves 405 via the controller, so that after the rainwater flows through the conical groove 401 into the collection hole 402, it can flow directly into the water storage tank 3 through the collection pipe 403 and the inlet pipe 404, thus allowing the water storage tank 3 to collect the rainwater. When the rain stops, the optical rain sensor can close all the electric valves 405 via the controller. This setting ensures that when the lawn layer 203 is being irrigated, the water can always remain inside the lawn layer 203. When it rains, the water storage tank 3 can collect the rainwater normally, so that the rainwater can be reused.

[0039] In one embodiment, the separation component 5 includes a collecting hopper 501, which is fixedly installed on the inner wall of the water storage tank 3. A feeding pipe 502 is fixedly connected to one side of the water storage tank 3. The feeding pipe 502 is located on the upper side of the collecting hopper 501. A discharge pipe 503 is fixedly connected to the bottom of the collecting hopper 501, and one end of the discharge pipe 503 extends to the outer side of the water storage tank 3.

[0040] The feeding pipe 502 can be connected to an external flocculant transport pipe, which in turn is connected to a collection box containing the flocculant. When the rainwater collected above the collecting hopper 501 reaches a certain amount, the water level sensor can control the water pump inside the collection box via a controller, allowing the flocculant to flow into the water storage tank 3 in a certain amount. At this point, the flocculant can adsorb impurities in the rainwater, thus enabling solid-liquid separation. The separated solid impurities can settle at the top of the collecting hopper 501 under their own gravity. After solid-liquid separation and extraction of most of the purified water, the valve on the discharge pipe 503 can be opened. The solid impurities at the top of the collecting hopper 501 flow directly into the discharge pipe 503 under the impact of some water and the guidance of the collecting hopper 501. The wastewater inside the discharge pipe 503 can flow directly into the sewage pipe, thus enabling the sewage pipe to discharge wastewater.

[0041] In one embodiment, for the aforementioned water storage tank 3, a suction pipe 504 is fixedly installed on the top of the water storage tank 3. One end of the suction pipe 504 extends into the interior of the water storage tank 3, and the other end of the suction pipe 504 is fixedly connected to the front of the water storage tank 3. A suction pump 505 is fixedly installed on the front of the water storage tank 3. The suction pump 505 is connected to the suction pipe 504. A lifting pipe 511 is provided inside the suction pipe 504. A float 506 is provided on the outer surface of the lifting pipe 511. A rubber pad 507 is provided on the outer surface of the lifting pipe 511. The rubber pad 507 is in contact with the suction pipe 504.

[0042] After solid-liquid separation is completed, the extraction pump 505 is started (the extraction pump 505 can be started a certain time after the flocculant is added, and the start time can be determined by the amount of rainwater collected inside the water storage tank 3). At this time, the extraction pump 505 can extract the purified water to the lower side of the collecting hopper 501 through the extraction pipe 504 and the riser pipe 511, so that the water storage tank 3 can collect the purified water.

[0043] In one embodiment, for the water storage tank 3, a receiving tube 508 is fixedly installed on the top of the water storage tank 3, and a T-shaped guide rod 509 is movably connected inside the receiving tube 508. The T-shaped guide rod 509 passes through the water storage tank 3 and is fixedly connected to the float 506. A spring 510 is fixedly connected between the outward protruding part of the T-shaped guide rod 509 and the inner wall of the receiving tube 508.

[0044] As purified water is continuously extracted, the float 506 drives the lifting pipe 511 to move downwards, ensuring that the bottom of the lifting pipe 511 remains slightly below the water surface due to the buoyancy of the float 506. This design allows the lifting pipe 511 to extract purified water normally without extracting wastewater containing solid impurities. Furthermore, since the lifting pipe 511 is in contact with the inner wall of the extraction pipe 504 via the rubber gasket 507, the sealing at the connection point is guaranteed, ensuring the effectiveness of both the extraction pipe 504 and the lifting pipe 511 in extracting purified water.

[0045] In one embodiment, for the water storage tank 3, a receiving tube 508 is fixedly installed on the top of the water storage tank 3, and a T-shaped guide rod 509 is movably connected inside the receiving tube 508. The T-shaped guide rod 509 passes through the water storage tank 3 and is fixedly connected to the float 506. A spring 510 is fixedly connected between the outward protruding part of the T-shaped guide rod 509 and the inner wall of the receiving tube 508.

[0046] Spring 510 can pull the T-shaped guide rod 509 downward, thereby pushing the float 506 downward. This setting allows the float 506 to move downward normally with the water level when the water level drops, thus effectively avoiding the phenomenon that the float 506 cannot move downward due to the friction between the extraction pipe 504, the lifting pipe 511 and the rubber pad 507.

[0047] In one embodiment, the irrigation component 6 includes an installation cylinder 601 that penetrates the support plate 1, the vibration isolation layer 201, the pad plate 202, and the lawn layer 203. An irrigation pipe 602 is installed inside the installation cylinder 601, and a nozzle 603 is fixedly installed at the top of the irrigation pipe 602. An irrigation pump 604 is fixedly connected to the back of the water tank 3. The bottom end of the irrigation pipe 602 is connected to the irrigation pump 604. A connecting pipe 605 is fixedly connected to the bottom of the water tank 3 and is connected to the irrigation pump 604. A pressure regulating valve 606 is provided on the outer surface of the connecting pipe 605.

[0048] The pressure regulating valve 606 can qualitatively monitor the water volume of the purified water inside the water storage tank 3. The higher the pressure, the larger the water volume in the tank. Within a reasonable range, the pressure regulating valve 606 is closed. When the threshold is exceeded, the pressure regulating valve 606 automatically opens under water pressure. At this time, the water flows through the connecting pipe 605 to the irrigation pump 604. After the water flow sensor installed at the irrigation pump 604 detects the water flow, it controls the irrigation pump 604 through the controller, so that the irrigation pump 604 draws purified water through the connecting pipe 605. The drawn purified water flows directly to the sprinkler head 603 under the guidance of the irrigation pipe 602, so that the sprinkler head 603 can spray purified water onto the lawn layer 203. When the threshold inside the water storage tank 3 drops to a certain level, the pressure regulating valve 606 closes. The above settings allow the purified water inside the water storage tank 3 to be reused, and at the same time, the water storage tank 3 can always ensure the collection effect of purified water.

[0049] In one embodiment, the support plate 1 is fixedly connected to a support frame 7 at its bottom.

[0050] The support frame 7 can support the support plate 1, so that the components at the bottom of the support plate 1 will not be subjected to excessive compressive force, thus allowing the components at the bottom of the support plate 1 to work normally; at the same time, the support frame 7 is set on the lower side of the mine surface, so that the grass layer 203 can better contact the mine surface under the support of the support frame 7.

[0051] Through the above technical solution, 1) the support plate 1 can block moisture inside the repair layer 2, so that when irrigating the repair layer 2, the moisture can always remain inside the repair layer 2; when it rains, the collection component 4 can be opened, allowing the water storage tank 3 to collect the seeping water, and the irrigation component 6 can then use the collected rainwater for subsequent irrigation of the repair layer 2; in summary, the design that can block and collect moisture inside the repair layer 2 significantly improves the efficiency of water resource utilization during mine restoration. 2. The spring 510 pulls the T-shaped guide rod 509 downwards, so that the float 506 can always stay on the water surface under the push of the T-shaped guide rod 509 and the buoyancy. This setting allows the float 506 to move downwards normally with the water level when the water level drops. At the same time, with the support of the float 506, the bottom of the lift pipe 511 can always be slightly lower than the water surface. This setting allows the lift pipe 511 to always draw the upper layer of clean water when extracting clean water, effectively preventing the lift pipe 511 from sucking in the bottom sewage containing solid impurities.
