Description

Technical Field

[0001] The invention belongs to the technical field of slope protection, and specifically refers to a soil protection structure for mine ecological restoration. Background Art

[0002] After the ecological restoration of the mine, in order to ensure the ecological environment safety and human health after planting trees, it is necessary to wait for enough time to ensure that the heavy metal content in the soil drops to a safe level. During the waiting process, the soil needs to be protected to reduce the chance of soil erosion.

[0003] The existing soil protection structure has the following problems: The existing soil protection structure does not have the ability to accelerate the natural degradation of excessive pollutants remaining in the soil when protecting the soil for ecological restoration, resulting in a long wait time before the slope soil can be restored for vegetation planting, which increases the risk of soil erosion to a certain extent. In addition, the traditional soil protection structure cannot maintain the moisture of the protected soil, resulting in the loss of loose soil on the slope due to wind erosion. Therefore, it cannot meet the existing requirements for the use of soil protection structures. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the existing technology, this scheme provides a soil protection structure for mine ecological restoration that can accelerate the natural degradation of excessive pollutants remaining in the soil, maintain the wettability of the protected soil, and reduce the chance of soil loss due to wind erosion.

[0005] The technical scheme adopted in this scheme is as follows: A soil protection structure for mine ecological restoration proposed in this scheme includes a protection frame, a ground cone, a slider, a groove, a dust-proof wet soil mechanism, an enrichment guide mechanism, a heat-collecting energy supply mechanism and a blocking filter mechanism. Multiple groups of the ground cones are arranged on the bottom wall of the protection frame, the slider is symmetrically arranged on one side of the protection frame, the groove is symmetrically arranged on the side of the protection frame away from the slider, and the groove is open on three sides. The dust-proof wet soil mechanism is arranged on the inner wall of the protection frame, the blocking filter mechanism is arranged at one end of the protection frame close to the enrichment guide mechanism, the enrichment guide mechanism includes an anode mechanism and a cathode mechanism, the anode mechanism is arranged at both ends of the protection frame, and the cathode mechanism is arranged at one end of the protection frame away from the anode mechanism. The heat-collecting energy supply mechanism includes a collecting mechanism and an energy storage mechanism, the collecting mechanism is arranged on the inner wall of the protection frame, and the energy storage mechanism is arranged on the bottom wall of the collecting mechanism.

[0006] As a further preferred embodiment of the present invention, the dust-proof wet soil mechanism includes a protective plate, a wire mesh frame, an arc-shaped wire mesh and a guide groove, a plurality of groups of the protective plates are arranged on the inner wall of the protective frame, the wire mesh frame is arranged on the upper wall of the protective plate, the arc-shaped wire mesh is arranged between the wire mesh frames, a plurality of groups of the guide grooves are arranged between the wire mesh frames and the protective plates, and the guide grooves are opened on three sides.

[0007] When in use, the ground cone is inserted into the soil of the mine slope to be protected. Under the protection of the protective plate, the erosion of the slope soil by wind can be reduced. By using the wire mesh frame and curved wire mesh installed on the upper wall of the protective plate, when the humid air passes through the curved wire mesh, the water vapor in the air will condense into larger water droplets due to collision and adhesion on the surface of the curved wire mesh. The condensed water droplets inside the curved wire mesh fall into the slope soil under the action of gravity and the diversion of the diversion trough, which increases the soil humidity inside the protection area of ​​the protective frame, thereby reducing the chance of soil loss with wind, thereby better protecting the mine slope soil.

[0008] Preferably, the anode mechanism comprises an anode conductive rod, a positive limit plate and an anode spring, and multiple groups of the anode conductive rods are symmetrically arranged at both ends of the protective frame, the anode conductive rods are arranged through the inner wall of the protective frame, the positive limit plate is arranged on the upper wall of the anode conductive rod, the anode spring is arranged between the positive limit plate on the outside of the anode conductive rod and the protective frame, and the anode spring is compressed; the cathode mechanism comprises a cathode conductive rod, a negative limit plate and a cathode spring, and multiple groups of the cathode conductive rods are arranged through the inner wall of one end of the protective frame away from the anode conductive rod, the negative limit plate is arranged on the upper wall of the cathode conductive rod, the cathode spring is arranged between the negative limit plate on the outside of the cathode conductive rod and the protective frame, and the cathode spring is compressed.

[0009] When in use, the anode conductive rod utilizes the deformation of the anode spring to fit the soil surface, pressing the positive limit plate, which drives the anode conductive rod to insert into the slope soil, and pressing the negative limit plate, which drives the cathode conductive rod to insert into the slope soil.

[0010] Specifically, the collection mechanism includes a heat collecting frame, a supporting plate and a photovoltaic panel. The heat collecting frame is arranged on the inner wall of the middle part of the protective frame, the supporting plate is arranged on the upper wall of the heat collecting frame, and the photovoltaic panel is arranged on the upper wall of the supporting plate; the energy storage mechanism includes a rectifier and a battery, and the rectifier and the battery are respectively arranged on the bottom wall of the supporting plate.

[0011] When in use, the heat collecting frame faces the sun's irradiation surface so that the sun can shine on the surface of the photovoltaic panel. The photovoltaic panel will store the generated electricity into the battery after rectification by the rectifier. The current derived from the positive electrode of the battery enters the anode conductive rod, and the current derived from the negative electrode of the battery enters the cathode conductive rod.

[0012] Among them, the blocking type filtering mechanism includes a connecting ring plate, an intercepting inner mesh sleeve, an intercepting outer mesh sleeve and activated carbon adsorption particles, the connecting ring plate is arranged on the bottom wall of the protective frame outside the cathode conductive rod, the connecting ring plate is threadedly connected to the protective frame, the intercepting inner mesh sleeve is arranged on the bottom wall of the connecting ring plate outside the cathode conductive rod, the intercepting outer mesh sleeve is arranged on the bottom wall of the connecting ring plate outside the intercepting inner mesh sleeve, and the activated carbon adsorption particles are arranged between the intercepting inner mesh sleeve and the intercepting outer mesh sleeve.

[0013] When in use, after the anode conductive rod and the cathode conductive rod are inserted into the soil, the cathode conductive rod is located at the end of the protective frame away from the anode conductive rod, and the cathode conductive rod is set at the target position, which is convenient for filtering out heavy metals inside the soil. Heavy metal ions are positively charged. Under the action of the electric field, the heavy metal ions move toward the cathode conductive rod and gradually accumulate at the target position. As the cathode conductive rod attracts the heavy metal ions, the heavy metal ions enter the interception inner mesh sleeve and the interception outer mesh sleeve in the process of approaching the cathode conductive rod and are captured by the activated carbon adsorption particles, thereby reducing the content of heavy metals inside the soil.

[0014] Preferably, a controller is provided on an upper wall of one end of the protection frame close to the cathode conductive rod.

[0015] Furthermore, the controller is electrically connected to the photovoltaic panel, the rectifier and the battery respectively.

[0016] Furthermore, the model of the controller is SYC89C52RC-401.

[0017] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, this solution adopts a wire mesh interception method, through the dust-proof wet soil mechanism, enrichment guide mechanism, heat collection energy supply mechanism and blocking filtration mechanism, the arc wire mesh is used to collect water vapor in the air. Under the diversion effect of the diversion trough, on the one hand, the soil surface can be wetted, reducing the probability of slope soil loss under wind erosion, and improving the protective effect of the protection frame and the protective plate on the soil. On the other hand, heavy metal ions migrate under the action of the electric field, mainly through the movement of aqueous solution in the soil pores. When the arc wire mesh collects more water vapor, the number of water droplets dripping from the diversion trough to the inside of the slope soil increases, the humidity inside the soil is increased, the migration path of heavy metal ions is strengthened, and the collection operation of heavy metal ions inside the soil is accelerated, thereby shortening the time for the slope to restore vegetation after repair, and to a certain extent improving the protective effect of the soil after mine ecological restoration.

[0028] A controller 32 is disposed on the upper wall of one end of the protection frame 1 close to the cathode conductive rod 16 .

[0029] The controller 32 is electrically connected to the photovoltaic panel 23 , the rectifier 25 and the battery 26 , respectively.

[0030] The model of the controller 32 is SYC89C52RC-401.

[0031] When in use, multiple sets of protection frames 1 are inserted into the soil of the mine slope to be protected through the ground cone 2. The protection frames 1 are connected by the slider 3 and the groove 4. The heat collecting frame 21 faces the sun's irradiation surface so that the sun can irradiate the surface of the photovoltaic panel 23. The anode conductive rod 12 is in contact with the soil surface by the deformation of the anode spring 14. Under the protection of the protective plate 6, the slope soil can reduce the erosion of the wind on the slope soil. By using the wire mesh frame 7 and the curved wire mesh 8 installed on the upper wall of the protective plate 6, when the moist air passes through the curved wire mesh 8, the water vapor in the air will condense into larger water droplets due to collision and adhesion on the surface of the curved wire mesh 8. The water droplets condensed inside the curved wire mesh 8 fall into the slope soil under the guidance of gravity and the diversion of the diversion groove 9, so that the soil humidity inside the protection area of ​​the protective frame 1 is increased, thereby reducing the probability of soil loss with wind force, so as to better protect the mine slope soil; Secondly, the controller 32 controls the photovoltaic panel 23, the rectifier 25, and the battery 26 to start, manually presses the positive limit plate 13, and the positive limit plate 13 drives the anode conductive rod 12 to be inserted into the inside of the slope soil, and manually presses the negative limit plate 17, and the negative limit plate 17 drives the cathode conductive rod 16 to be inserted into the inside of the slope soil.

The stronger the sunlight, the more electricity the photovoltaic panel 23 generates, and the anode conductive rod 12 and the cathode conductive rod 16 promote the migration speed of heavy metal ions in the soil. The reduction of light intensity will lead to a reduction in the power generation of the photovoltaic panel 23, so that the migration effect of the anode conductive rod 12 and the cathode conductive rod 16 on the heavy metal ions in the soil is weakened; After the anode conductive rod 12 and the cathode conductive rod 16 are inserted into the soil, the cathode conductive rod 16 is located at the end of the protective frame 1 away from the anode conductive rod 12, and the cathode conductive rod 16 is set at the target position. Since the protective frame 1 is inclined, the position of the anode conductive rod 12 is higher than the cathode conductive rod 16, and the heavy metal ions are positively charged. Under the action of the electric field, the heavy metal ions move toward the cathode conductive rod 16 and gradually accumulate at the target position. As the cathode conductive rod 16 attracts the heavy metal ions, the heavy metal ions enter the interception inner mesh sleeve 29 and the interception outer mesh sleeve 30 in the process of approaching the cathode conductive rod 16 and are captured by the activated carbon adsorption particles 31, thereby reducing the content of heavy metals in the soil, thereby achieving the goal of shortening the time for planting trees in the soil after mine restoration; the above operation can be repeated the next time it is used.
