Description

Technical Field

[0004] The invention relates to the technical field of ecological slope protection, and in particular to an ecological slope protection structure for water conservancy projects. Background Art

[0005] Ecological slope protection is a slope protection technology that integrates basic knowledge of engineering mechanics, soil science, ecology and botany to support slopes or slopes. By planting plants and utilizing the interaction between plants and rocks and soil (such as root anchoring), the surface of the slope is protected and reinforced, so that it can not only meet the requirements for the stability of the slope surface, but also restore the damaged natural ecological environment.

[0006] The most common slope protection is applied to rivers to prevent soil erosion on both sides of the river. The current ecological slope protection uses grass or geotechnical materials. The problem with this type of structure is that the durability is insufficient. This is because the growth of plants is restricted by the environment, especially in some arid areas or dry seasons. The precipitation is low and the water level in the river drops, which cannot provide sufficient water for the plants. Plants are difficult to survive, resulting in a significant reduction in the slope protection effect. Summary of the invention

[0007] The purpose of the present invention is to provide an ecological slope protection structure for water conservancy projects to solve the following technical problems: since the growth of plants is restricted by the environment, especially in some arid areas or dry seasons, the precipitation is less and the water level of the river drops, which cannot provide sufficient water for the plants, making it difficult for the plants to survive, resulting in a significant reduction in the slope protection effect.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] The water tank cap has one end which is connected to the water tank, and the other end is connected to the water tank via a filter.

[0010] As a further solution of the present invention: a planting opening is provided on the slope protection board for planting trees and vegetation.

[0011] As a further solution of the present invention: a guide rod is fixed between the top wall and the bottom wall of the transfer box, and a floating block is slidably connected to the guide rod.

[0012] As a further solution of the present invention: support tubes are symmetrically arranged on the top wall of the water storage tank, support rods are arranged on the top wall of the support tubes, and the top ends of the support rods are fixedly connected to the cross arms.

[0013] As a further solution of the present invention: the support rod is slidably connected to the top wall of the support tube, a plurality of air holes are opened on the top wall of the support tube, a cushion block is fixed to the bottom end of the support rod, an expansion block is arranged in the support tube, and the expansion block is located below the cushion block.

[0014] As a further solution of the present invention: the expansion block is made of water-absorbing and swelling rubber.

[0015] As a further solution of the present invention: sealing columns are symmetrically installed on the bottom wall of the water tank, circular holes are symmetrically opened on the floating plate, two sealing columns are respectively located directly below the two circular holes and have matching sizes, and second absorbent cotton threads are connected to the sealing columns. The two second absorbent cotton threads respectively pass through the two circular holes, the top wall of the water tank and the bottom wall of the support tube and extend into the support tube.

[0016] As a further solution of the present invention: connecting holes are symmetrically opened on the floating plate, an annular magnetic part is fixed to the outside of the connecting hole, an adsorption part is adsorbed on the magnetic part, a spring is connected to the adsorption part, one end of the spring is connected to the top wall of the water tank, and an airbag is fixed on the adsorption part.

[0017] As a further solution of the present invention: support blocks are symmetrically arranged on the bottom wall of the water storage tank.

[0018] Beneficial effects of the present invention:

[0019] (1) The present invention is provided with a water storage tank and a water inlet pipe. In normal seasons, when the rainfall is sufficient and the river water level is normal, the water storage tank will collect water from the river through the connecting pipe; in the dry season, when the river water level drops, the floating plate drops, and the stored water is transported to the planting port on the slope protection plate through the first water-absorbing cotton thread, ensuring that water can be provided to the plants in the dry season, which can effectively deal with the problem of insufficient precipitation in arid areas and improve the durability and ecological effect of the slope protection;

[0020] (2) The present invention supports the cross arm by providing a support tube and a support rod, thereby ensuring the stability of the cross arm. At the same time, due to the provision of an expansion block, in normal seasons, the expansion block absorbs water to increase its volume and supports the support rod. In dry seasons, the expansion block dries and restores its volume, and does not hinder the descent of the floating plate.

[0021] (3) The present invention provides a second absorbent cotton thread to continuously provide moisture to the expansion block in normal seasons. When the floating plate descends, the sealing column will enter the circular hole. At this time, moisture can no longer be supplied to the expansion block, and the expansion block will automatically recover. BRIEF DESCRIPTION OF THE DRAWINGS

In normal seasons, the water level is normal, and the ventilation pipe 5 connects the water tank 1 with the external atmosphere. According to the connecting vessel principle, the water level in the water tank 1 is maintained at the same height, and the floating plate 10 floats on the water surface. When the water level drops in the dry season, the floating plate 10 drops accordingly. When the floating plate 10 drops to the height of the baffles 11 on both sides, the bottom of the floating plate 10 will no longer be connected to the external atmosphere, which can reduce the volatilization of water. Under the action of gravity, the floating plate 10 slowly drops, and the river water at the bottom of the floating plate 10 is sent into the transfer box 6 through the hose 13 and the water inlet pipe 12. The first absorbent cotton thread 7 absorbs the river water in the transfer box 6 to supply water for the plants on the slope protection, which can effectively cope with the problem of insufficient precipitation in arid areas and improve the durability and ecological effect of the slope protection.

[0034] See also Figure 3 and Figure 4 A guide rod 14 is fixed between the top wall and the bottom wall of the transfer box 6, and a floating block 15 is slidably connected to the guide rod 14; when the water volume in the transfer box 6 is sufficient, the floating block 15 rises to block the water inlet of the water inlet pipe 12, which can avoid excessive water volume and reduce the waste of aqueous solution.

[0035] See also Figure 2 and Figure 3A support tube 17 is symmetrically arranged on the top wall of the water tank 1, and a support rod 18 is arranged on the top wall of the support tube 17, and the top end of the support rod 18 is fixedly connected to the cross arm 16; the support tube 17 and the support rod 18 support the cross arm 16 to ensure the stability of the cross arm 16 and prevent the cross arm 16 from shaking due to normal water level fluctuations.

[0036] See also Figure 3 , Figure 5 and Figure 6 The support rod 18 is slidably connected to the top wall of the support tube 17. A plurality of air holes 19 are provided on the top wall of the support tube 17. A cushion block 20 is fixed to the bottom end of the support rod 18. An expansion block 21 is provided in the support tube 17, and the expansion block 21 is located below the cushion block 20. The expansion block 21 is made of water-absorbing and expanding rubber. Sealing columns 23 are symmetrically installed on the bottom wall of the water storage tank 1. Circular holes are symmetrically provided on the floating plate 10. Two sealing columns 23 are respectively located directly below the two circular holes and have matching sizes. A second water-absorbing cotton thread 22 is connected to the sealing column 23. The two second water-absorbing cotton threads 22 are connected to the sealing column 23. The water cotton thread 22 passes through the two circular holes, the top wall of the water storage tank 1 and the bottom wall of the support tube 17 respectively and extends into the support tube 17; the expansion block 21 is a water-absorbing and expanding rubber, and the second water-absorbing cotton thread 22 supplies water to the expansion block 21. The expansion block 21 absorbs water and its volume increases to support the support rod 18. In the dry season, the water level drops, the moisture in the expansion block 21 gradually evaporates, and at the same time the float 10 drops, the sealing column 23 enters the circular hole of the float 10, and the second water-absorbing cotton thread 22 cannot supply water, so that the volume of the expansion block 21 is restored, thereby not hindering the descent of the float 10.

[0037] See also Figure 3 and Figure 7 , the floating plate 10 is symmetrically provided with connecting holes, an annular magnetic member 24 is fixed to the outside of the connecting hole, an adsorption member 26 is adsorbed on the magnetic member 24, a spring 25 is connected to the adsorption member 26, one end of the spring 25 is connected to the top wall of the water storage tank 1, and an air bag 27 is fixed to the adsorption member 26; support blocks 28 are symmetrically arranged on the bottom wall of the water storage tank 1; when the floating plate 10 descends, the spring 25 will be stretched, and under the action of magnetic force, the magnetic member 24 and the adsorption member 26 will not separate. When the dry season is over, the water level gradually rises, and the river Water will also enter the water tank 1 again, and the river water will first fall on the surface of the floating plate 10. Under the action of buoyancy and the elastic force of the spring 25, the magnetic part 24 and the adsorption part 26 will separate, causing the floating plate 10 to drop and connect with the atmosphere again. The river water can then enter the bottom of the floating plate 10 through the connecting hole, and the floating plate 10 will rise and return to its original position without human intervention.

It is worth mentioning that the magnetic part 24 is a magnet, the adsorption part 26 is made of iron material, and the surface is coated with anti-rust paint.

[0038] The working principle of the present invention is as follows: one end of the connecting pipe 3 is located in the river channel. In normal seasons, the water level is normal, and the ventilation pipe 5 connects the water storage tank 1 with the external atmosphere. According to the connecting vessel principle, the water level in the water storage tank 1 is maintained at the same height, and the floating plate 10 floats on the water surface. In the dry season, the water level drops, and the floating plate 10 drops accordingly. When the floating plate 10 drops to the height of the baffles 11 on both sides, the bottom of the floating plate 10 will no longer be connected to the external atmosphere, which can reduce the volatilization of water. Under the action of gravity, the floating plate 10 slowly drops, and the river water at the bottom of the floating plate 10 is sent into the transfer box 6 through the hose 13 and the water inlet pipe 12. The first absorbent cotton thread 7 absorbs the river water in the transfer box 6 to supply water to the plants on the slope protection, which can effectively deal with the problem of insufficient precipitation in arid areas and improve the durability and ecological effect of the slope protection.

[0039] The support tube 17 and the support rod 18 support the cross arm 16 to prevent the normal water level fluctuation from causing the cross arm 16 to shake, and the second absorbent cotton thread 22 supplies water to the expansion block 21, and the expansion block 21 absorbs water to increase its volume, thereby stably supporting the support rod 18. In the dry season, the water level drops, the water in the expansion block 21 gradually evaporates, and at the same time the floating plate 10 drops, the sealing column 23 enters the circular hole of the floating plate 10, and the second absorbent cotton thread 22 cannot supply water, so that the expansion block 21 recovers its volume, thereby not hindering the descent of the floating plate 10;

[0040] When the floating plate 10 descends, the spring 25 will be stretched. Under the action of magnetic force, the magnetic part 24 and the adsorption part 26 will not separate. After the dry season, the water level of the river channel gradually rises, and the river water will enter the water storage tank 1 again. The river water will first fall on the surface of the floating plate 10. Under the combined action of buoyancy and the elastic force of the spring 25, the magnetic part 24 and the adsorption part 26 will separate, causing the floating plate 10 to descend and connect with the atmosphere again. The river water can then enter the bottom of the floating plate 10 through the connecting hole. The floating plate 10 rises and resets without manual intervention. The function of the support block 28 is to prevent the floating plate 10 from touching the bottom and being difficult to reset.
