Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological restoration, and particularly relates to a re-greening device for mine ecological restoration. BACKGROUND

[0002] After mining, due to the removal of vegetation, the exposed rock wall is prone to water and soil loss, resulting in frequent occurrence of problems such as landslides and mudslides, which destroys the original natural ecosystem, and thus it is necessary to restore the ecology of the mine, restore the vegetation on the rock wall, and realize the sustainable development of the ecological environment.

[0003] There are various ways of ecological restoration of mines, such as slope drilling greening, net hanging and spraying greening, and vegetation concrete greening, which need to be adapted to local conditions and select appropriate restoration methods according to different slopes and environments. For the northwest region, due to the influence of windy weather, it is difficult to achieve the fixation and protection of the primary green plants by using the methods of net hanging and spraying greening and vegetation concrete greening, so some primary green plants are easily blown away. Therefore, it is generally necessary to drill planting grooves on the slope to plant green plants, and the planting grooves are used to protect the green plants to avoid the influence of strong winds in the early stage.

[0004] When using planting grooves to plant green plants for ecological restoration, the green plants need to be irrigated in addition to relying on their own water absorption in rainy days to ensure their growth. Currently, there are two ways of irrigation. One is to manually irrigate the green plants by using a spraying device. For mines, the area to be sprayed is large, and the wall surface is steep, so the spraying construction is difficult. The other way is to set a rainwater collecting device near the green plants, and use the rainwater collecting device to collect the rainfall in rainy days to supply water to the green plants in dry weather. However, since the green plants are in the early growth stage, the slope of the mine is still in a bare state and is easily exposed to direct sunlight. The rainwater collecting device is affected by sunlight and dry environment, causing some of the stored rainwater to evaporate and be lost. Especially during a long period without rainfall, the stored rainwater is exhausted in advance, which makes it difficult to effectively supply water to the green plants in time and reduces the survival rate of the green plants.

[0042] In the embodiment of the present application, in rainy days, the annular plate 3 and the plurality of baffles 5 are rotated around the inner barrel body 2 by the rotating part 6 when the water is collected by the outer barrel body 1, the plurality of baffles 5 are rotated and are dislocated with the plurality of groups of water collecting holes 31, so that the plurality of groups of water collecting holes 31 are opened, at this time, part of the falling rainwater can enter the outer barrel body 1 to be stored through the plurality of groups of water collecting holes 31, and part of the falling rainwater can enter the inner barrel body 2 to directly supply water to the planted plants, when the rainfall ends, the rotating part 6 drives the plurality of baffles 5 to rotate reversely and moves to the positions directly below the plurality of groups of water collecting holes 31, so that the plurality of groups of water collecting holes 31 are shielded, and the barrel opening of the outer barrel body 1 is closed, in the subsequent non-rainy and dry weather, the stored rainwater is prevented from evaporating and losing, and the planted plants in the inner barrel body 2 are continuously supplied with water through the water diversion assembly, so that the survival rate of the green plants is improved.

[0043] The rotating part 6 comprises a box 61, a moving frame 63, a screw-nut transmission pair, a lever 66, a rotating column 67 and an elastic reset member 68. The box 61 is fixed on the outer wall of the barrel opening of the outer barrel 1. A row of first water inlets 611 are formed on the top of the box 61. The inside of the box 61 is divided into an upper cavity and a lower cavity by a partition plate 62. The partition plate 62 is close to one end of the outer barrel 1 and a first opening 621 is formed on the partition plate 62. A second opening 622 is formed between the lower cavity and the outer barrel 1. The moving frame 63 is slidingly arranged in the upper cavity of the box 61 and is located directly below the row of first water inlets 611. The screw-nut transmission pair comprises a screw 64 and a nut 65. One end of the screw 64 is fixed opposite to the side wall of the outer barrel 1 of the moving frame 63. The screw 64 is arranged along the radial direction of the outer barrel 1. One end of the nut 65 is connected with the other end of the screw 64. The other end of the nut 65 is rotationally connected with the inner wall of the box 61 through a bearing. One end of the lever 66 is fixed with the bottom of the nut 65. The other end of the lever 66 extends into the lower cavity through the first opening 621. A slot 661 is formed on the lever 66 along the length direction of the lever 66. One end of the rotating column 67 is slidingly connected in the slot 661. The other end of the rotating column 67 is fixed with the side wall of one of the baffles 5 through the second opening 622. The elastic reset member 68 is connected between the moving frame 63 and the box 61 and is located directly above the screw 64. The elastic reset member 68 is used to reset the moving frame 63 to move along the axial direction of the screw 64.

[0044] In the embodiment of the present application, the rotating part 6 is actually driven by the gravity of the rainwater to rotate the plurality of baffles 5. In a non-rainy day, the elastic return member 68 is naturally elongated, so that the moving frame 63 is located directly below the first water inlet hole 611, and the plurality of baffles 5 are located directly below the plurality of water collecting holes 31 and shield and close the water collecting holes 31, thereby avoiding the loss of evaporation of rainwater caused by sunlight. In a rainy day, part of the rainwater enters the moving frame 63 through the row of first water inlet holes 611. Since the box body 61 is installed on a slope, it is affected by the gravity of the rainwater. When the rainwater accumulated in the moving frame 63 gradually increases, the moving frame 63 as a whole moves along the axial direction of the lead screw 64 and squeezes the elastic return member 68. The moving frame 63 moves synchronously with the lead screw 64. Since the nut 65 is rotationally connected to the inner wall of the box body 61 through a bearing, it converts the linear motion into rotary motion, thereby squeezing the nut 65 to rotate. The rotation of the nut 65 drives the lever 66 to rotate synchronously. Since one end of the rotating column 67 is slidingly connected in the notch 661 formed on the lever 66, the rotation of the lever 66 drives the rotating column 67 to rotate, so that the rotating column 67 drives the baffle 5 and the annular plate 3 fixedly connected thereto to rotate around the inner drum 2, so that the plurality of baffles 5 are rotated and are out of position with the plurality of water collecting holes 31, thereby opening the plurality of water collecting holes 31. At this time, part of the falling rainwater enters the outer drum 1 through the plurality of water collecting holes 31 for storage. When the rain stops, as the rainwater in the moving frame 63 gradually evaporates through the first water inlet hole 611, the elastic force of the elastic return member 68 is greater than the weight of the moving frame 63 as a whole, thereby driving the moving frame 63 to return to the initial position. In contrast to the above transmission process, the plurality of baffles 5 are reversely rotated to re-shield the plurality of water collecting holes 31.

[0045] Further, as shown in Figure 4 and Figure 7 , the box body 61 is fan-shaped, and the row of first water inlet holes 611 is uniformly arranged along the arc-shaped path on the top of the box body 61. Therefore, the moving frame 63 in the embodiment includes a first arc-shaped plate 631, a second arc-shaped plate 632, and two enclosing plates 633. The first arc-shaped plate 631 is arranged in parallel above the second arc-shaped plate 632, and the two enclosing plates 633 are fixed between the first arc-shaped plate 631 and the second arc-shaped plate 632. The first arc-shaped plate 631 and the second arc-shaped plate 632 are concentrically arranged with the box body 61, and the first arc-shaped plate 631 is arranged in close contact with the side wall of the box body 61 opposite to the box body 61. The end of the lead screw 64 is fixed to the middle side wall of the second arc-shaped plate 632, and the elastic return member 68 is connected between the second arc-shaped plate 632 and the box body 61. In order to adapt to the shape of the box body 61 and the outer drum 1, the shape of the first opening 621 and the shape of the second opening 622 are both arc-shaped.

[0046] By setting the box 61 to be a fan shape, it can be conveniently attached and fixed on the outer wall of the outer barrel body 1, the moving frame 63 is in a fan shape as a whole, which matches the shape of the box 61, so that it can move in the box 61, avoiding the edges and corners of the moving frame 63 from touching the inner wall of the box 61, and in order to adapt to the shape of the moving frame 63, a row of first water inlet holes 611 are evenly distributed in an arc shape, and in this way, the rainwater entering each first water inlet hole 611 can also maintain the same height, avoiding height differences that affect the moving process of the moving frame 63.

[0047] Further, as shown in Figure 1 and Figure 7 , the box 61 is provided with a plurality of second water inlet holes 612 on the side wall opposite to the first arc-shaped plate 631, and the side wall of the box 61 provided with the plurality of second water inlet holes 612 is convex in a mine slope shape, and the second arc-shaped plate 632 is provided with an auxiliary pushing assembly on the end portion on both sides of the lead screw 64, respectively, and the auxiliary pushing assembly is used to push the moving frame 63 to move along the axial direction of the lead screw 64 after the rainwater enters the box 61 through the second water inlet hole 612, and the auxiliary pushing assembly comprises an arc-shaped receiving groove, an arc-shaped plate 71 and an arc-shaped spring 72, the arc-shaped receiving groove is provided on the end portion of the second arc-shaped plate 632 and is concentrically arranged with the second arc-shaped plate 632, one end of the arc-shaped plate 71 is slidably arranged in the arc-shaped receiving groove, the other end of the arc-shaped plate 71 is slidably connected with the inner wall of the box 61, the arc-shaped spring 72 is arranged in the arc-shaped receiving groove, one end of the arc-shaped spring 72 is connected with the other end of the arc-shaped plate 71, and the other end of the arc-shaped spring 72 is connected with the groove wall of the arc-shaped receiving groove.

[0048] In the embodiment of the application, considering that the speed of moving the moving frame 63 by using the accumulated water entering the moving frame 63 through a row of first water inlet holes 611 alone is relatively slow, a plurality of second water inlet holes 612 are arranged on the side wall of the box 61 opposite to the first arc-shaped plate 631, and it should be noted that when it is not raining, the first arc-shaped plate 631 closes the plurality of second water inlet holes 612 under the elastic force of the elastic return member 68, and since the box 61 is in a fan shape, part of the side wall is convex in a mine slope shape, so that the soil and rock blocks falling from the plants above can be resisted and guided to slide to the two sides, avoiding causing collision damage to the plants, when it is raining, part of the rainwater entering the moving frame 63 through a row of first water inlet holes 611 pushes the moving frame 63 to slide along the slope, so that the first arc-shaped plate 631 no longer closes the plurality of second water inlet holes 612, and therefore part of the rainwater can enter the upper side of the moving frame 63 through the second water inlet hole 612, and as the amount of entering rainwater increases, Figure 7As shown, thereby extruding the upper side of the first arc-shaped plate 631 and the two arc-shaped plates 71, further pushing the moving frame 63 to move downward, and due to the presence of the arc-shaped spring 72, the outer end of the arc-shaped plate 71 can always be in contact with the inner wall of the box body 61 during the moving process, thereby preventing water leakage, maintaining the continuous pressure on the elastic return member 68, and driving the rotating rod 66 to rotate through the screw nut transmission pair, thereby fluctuating the rotating column 67 and rotating the plurality of baffles 5 to open the plurality of groups of water collecting holes 31.

[0049] Further, in order to guide and limit the moving position of the arc-shaped plate 71, a limiting sliding groove 613 is formed on the side wall of the box body 61 opposite to the arc-shaped plate 71, and the limiting sliding groove 613 is arranged along the radial direction of the outer barrel body 1, and the end of the arc-shaped plate 71 is slidably connected with the limiting sliding groove 613.

[0050] Further, in order to facilitate the introduction of part of the rainwater into the inner barrel body 2 for watering, the annular plate 3 is tapered, and the inner ring height of the annular plate 3 is lower than the outer ring height, and the top of the baffle 5 is provided with an inclined surface parallel to the tapered surface of the annular plate 3.

[0051] Further, in order to improve the storage and sealing effect of the rainwater entering the outer barrel body 1 through the water collecting hole 31, the annular cover plate 8 is sleeved and fixed between the outer barrel body 1 and the inner barrel body 2, the lowest part of the annular cover plate 8 is provided with a mounting hole, the water conveying pipe 81 is fixed in the mounting hole, the water conveying pipe 81 is provided with a one-way valve 82, the storage cavity surrounded by the outer barrel body 1 and the inner barrel body 2 is divided into two layers by the annular cover plate 8, and the one-way valve 82 is arranged to enable the rainwater to enter the outer barrel body 1 through the water conveying pipe 81, but cannot be discharged from the water conveying pipe 81, thereby further sealing and storing the rainwater in the lower layer storage cavity below the annular cover plate 8, and the excess rainwater is still stored in the upper layer storage cavity above the annular cover plate 8, so as to be supplemented into the lower layer storage cavity through the water conveying pipe 81 at any time.

[0052] Further, in order to facilitate the introduction of the rainwater falling above the annular cover plate 8 into the water conveying pipe 81, the mounting hole and the end of the water conveying pipe 81 fixed in the mounting hole are both trumpet-shaped, and the water conveying pipe 81 is provided with a trumpet-shaped port, which can better guide the inflow into the water conveying pipe 81.

[0053] Further, the inner barrel body 2 is provided with a planting soil layer for planting plants, wherein the water guide assembly is a cotton bar 9, one end of the cotton bar 9 is fixed on the inner bottom surface of the outer barrel body 1, and the other end of the cotton bar 9 extends into the inner planting soil layer after passing through the inner barrel body 2, and the cotton bar 9 can guide the rainwater stored in the outer barrel body 1 into the planting soil layer in the inner barrel body 2, thereby realizing the automatic watering process and ensuring the growth of the plants.

[0054] Further, in order to also be able to absorb the moisture of the surrounding soil to supply water to the planting soil layer, a plurality of groups of permeation holes 21 are formed on the circumferential barrel wall of the inner barrel 2 outside the outer barrel 1.

[0055] To sum up, the shielding assembly composed of the rotating part, the mounting ring and the plurality of baffles can drive the annular plate and the plurality of baffles to rotate by the rotating part in rainy days, the plurality of baffles are dislocated with the plurality of groups of water collecting holes after rotating, so that the plurality of groups of water collecting holes are opened, part of the falling rainwater enters the outer barrel for storage through the plurality of groups of water collecting holes, when the rainfall ends, the plurality of baffles are reversely rotated by the rotating part and are moved to the directly below the plurality of groups of water collecting holes, so that the plurality of groups of water collecting holes are shielded, the closing process of the barrel mouth of the outer barrel is formed, in the subsequent non-rainy and dry weather, the evaporation loss of the stored rainwater is prevented, and the plants planted in the inner barrel are continuously supplied with water by the water guiding assembly, so that the survival rate of the green plants is improved.
