Description

Technical Field

[0001] This invention relates to the field of ecological riverbank structure technology, specifically to a drawdown zone vegetation enhancement system and its control method. Background Technology

[0002] Large lakes and reservoirs often develop a drawdown zone as water levels rise and fall. As water levels continue to drop, the drawdown zone becomes more prominent, sometimes leading to serious ecological crises. The drawdown zone is a phenomenon unique to rivers, lakes, and reservoirs. After a lake forms or a reservoir is built, the high water level in winter and the lower flood control level in summer expose the land beneath the water level difference; this is the drawdown zone.

[0003] The drawdown zone, also known as the drawdown area, refers to the area where the land submerged in a reservoir periodically emerges from the water surface due to seasonal rises and falls in water level. Vegetation restoration in the drawdown zone has always been a difficult research topic both domestically and internationally, and is a world-class problem. It requires finding amphibious plants that are drought-resistant in summer, flood-resistant in winter, and erosion-resistant, while also finding ways to retain a certain amount of soil for the plants to take root and grow.

[0004] The management of drawdown zones is a crucial part of lake or reservoir ecological protection. Once a drawdown zone forms, most plants that originally grew in this area struggle to survive due to nearly six months of submersion. With the erosion of river water, this area becomes barren, even completely desolate. Its previous environmental protection functions are largely lost, and more pollutants enter the water, exacerbating eutrophication in the reservoir area. Without vegetation barriers, soil erosion along the reservoir banks becomes increasingly severe. From the perspective of aquatic ecological environment, the management and improvement of drawdown zones are essential. Summary of the Invention

[0005] This invention primarily addresses the shortcomings of existing technologies, such as soil erosion, poor ecological environment, and resource waste, by providing a vegetation enhancement system for drawdown zones and its control method. This system features a compact structure, high ecological protection, and high resource utilization. It also solves the problem of soil erosion caused by river embankments being easily washed away by river water.

[0006] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions:

[0007] A water level rise system for vegetation enhancement includes an ecological floating bed. The floating bed has wave-damping components on three sides. The floating bed comprises several interconnected floating bed frame rods forming a frame structure. Connecting joints are provided between adjacent floating bed frame rods. An aquatic plant fixing net is installed within each floating bed frame rod and is wound and fixed to it. A movable connecting shaft is located at the upper end of each floating bed frame rod. The movable connecting shaft is connected and fixed to the floating bed frame rod by bolts and clamps. Both ends of the movable connecting shaft are equipped with fixing piles that are movably limited and sleeved with the shaft. When the water level rises, the water flow or waves can cause erosion and damage to the aquatic plants on the fixing net. The wave-damping components protect the aquatic plants from damage caused by rising water levels.

[0008] Preferably, the ecological floating bed is equipped with a water pump on its outer side, with an inlet pipe at one end and a supply pipe at the other end. The ecological floating bed is equipped with a drip irrigation pipe connected to the supply pipe. The drip irrigation pipe is a connecting hose and has several drip nozzles that are evenly spaced and connected to the drip irrigation pipe.

[0009] Preferably, the side of the water pump is provided with a solar battery that is connected to the circuit of the water pump, the upper end of the solar battery is provided with a solar panel, a steering bracket is provided between the solar panel and the solar battery, and an external cable is provided between the solar battery and the water pump.

[0010] Preferably, the fixed pile includes a wooden pile, the upper end of which is provided with a rotating shaft seat that is movably limited and sleeved with the movable connecting shaft. The rotating shaft seat and the wooden pile are fixed by a threaded connection. Ground nails are provided on both outer sides of the wooden pile. Fixed ear nails are provided on both sides of the wooden pile and are threadedly inserted and fixed to the wooden pile. A steel wire is provided between the fixed ear nails and the ground nails.

[0011] Preferably, the wave-breaking component includes an inflatable wave-breaking guardrail, with an inflatable component facing the water flow on the side of the inflatable wave-breaking guardrail, an air supply pipe between the inflatable component and the inflatable wave-breaking guardrail, several air inlet pipes between the air supply pipe and the inflatable wave-breaking guardrail, a one-way valve between the air supply pipe and the inflatable component, an air release valve at the lower end of the inflatable wave-breaking guardrail, and both side walls of the inflatable wave-breaking guardrail being made of corrugated overlapping wave-breaking rubber walls.

[0012] Preferably, the inflatable assembly includes an inflatable frame with a drive shaft inside. The drive shaft has several water wheels that are nested and fixed to it with spring clips. Bearing seats are located between both ends of the drive shaft and the inner wall of the inflatable frame. One end of each bearing seat has a large drive gear isolated from water. The upper end of the large drive gear has a small driven gear that meshes with it. The small driven gear has a driven shaft that is nested and fixed to it with spring clips. A vacuum pump is located between the driven shaft and a one-way valve. The upper end of the vacuum pump has several suction pipes connected to the air supply pipes. The vacuum pump generates vacuum pressure, which pressurizes air and forces it into the inflatable wave-damping guardrail through the suction pipes.

[0013] Preferably, the connecting joints are two-way, three-way, or four-way depending on the connection position of the floating bed frame rod.

[0014] A control method for a drawdown zone vegetation lifting system includes the following steps: When the water level rises to the drawdown zone on the shore, the water pump does not operate. The ecological floating bed uses fixed piles and movable connecting shafts as fixed fulcrums, allowing the aquatic plant fixing net with aquatic plants to float on the water surface along with the frame structure composed of the floating bed skeleton and connecting joints. Because the ecological floating bed floats on the water surface, the wave-damping components around the ecological floating bed drive the water wheel through the turbulent water flow or wave impact, which in turn drives the large driving gear and the small driven gear on the drive shaft to mesh and transmit power. This allows the driven shaft to provide power to the vacuum pump, allowing the air intake pipe to pass through a one-way valve, an air supply pipe, and an air inlet pipe, finally inflating the inflatable wave-damping guardrail. This causes the corrugated overlapping wave-damping rubber wall to inflate and straighten, while the air release valve is closed in the water.

[0015] When the water level drops and the drawdown zone on the shore is exposed, the ecological floating bed attaches to the drawdown zone. The air release valve is released from the seal of the water body to release the air inside the inflatable wave-breaking guardrail. Water is then transported to the water supply pipe through the water pump inlet pipe. Then, through the drip irrigation pipe fixed to the ecological floating bed, the aquatic plants on the aquatic plant fixing net are irrigated by the drip nozzle.

[0016] As a preferred option, when the water level drops and the drawdown zone on the shore is exposed, the ecological floating bed is attached to the drawdown zone. On rainy days, it helps prevent soil erosion in the drawdown zone. On sunny days, solar panels and solar batteries are used to power the water pump. On cloudy days, an external cable is used for power supply.

[0017] Preferably, the connecting joint adopts a two-way structure to connect the floating bed frame at the four corners of the ecological floating bed, the connecting joint adopts a three-way structure to connect the floating bed frame on the four sides of the ecological floating bed, and the connecting joint adopts a four-way structure to connect the other floating bed frames inside the ecological floating bed.

[0018] The present invention can achieve the following effects:

[0019] This invention provides a vegetation enhancement system for drawdown zones and its control method. Compared with existing technologies, it features a compact structure, high ecological protection, and high resource utilization. It solves the problem of soil erosion caused by river embankments being easily washed away by river water. Attached Figure Description

[0028] The technical solution of the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0029] Example: Figure 1-7As shown, a vegetation enhancement system for drawdown zones includes an ecological floating bed 8.

A steering bracket 3 is installed between the solar panel 2 and the solar battery 1. An external cable 4 is installed between the solar battery 1 and the water pump 6. One end of the water pump 6 has an inlet pipe 5, and the other end has a water supply pipe 7. A drip irrigation pipe 9, connected to the water supply pipe 7, is installed on the ecological floating bed 8. The drip irrigation pipe 9 uses a connecting hose and has 168 equally spaced drip nozzles 22 connected to it.

[0030] The ecological floating bed 8 includes 22 floating bed frame rods 15 connected in a frame structure. Connecting joints 14 are provided between two adjacent floating bed frame rods 15, and the connecting joints 14 are either two-way, three-way, or four-way depending on the connection position of the floating bed frame rods 15. An aquatic plant fixing net 16 is provided inside the floating bed frame rod 15 and is wound and fixed to it. A movable connecting shaft 12 is provided at the upper end of the floating bed frame rod 15. The movable connecting shaft 12 is connected and fixed to the floating bed frame rod 15 by bolt clamps 13. Both ends of the movable connecting shaft 12 are provided with fixing piles 11 that are movably limited and sleeved with the movable connecting shaft 12. The fixed stake 11 includes a wooden stake 17. The upper end of the wooden stake 17 is provided with a rotating shaft seat 18 that is movably limited and sleeved with the movable connecting shaft 12. The rotating shaft seat 18 and the wooden stake 17 are fixed by a threaded sleeve. Ground nails 21 are provided on both outer sides of the wooden stake 17. Fixed ear nails 19 are provided on both sides of the wooden stake 17 and are threadedly inserted and fixed to the wooden stake 17. A steel wire 20 is provided between the fixed ear nails 19 and the ground nails 21.

[0031] The wave-damping component 10 includes an inflatable wave-damping guardrail 23. The side of the inflatable wave-damping guardrail 23 is provided with an inflatable component 27 facing the water flow. An air supply pipe 25 is provided between the inflatable component 27 and the inflatable wave-damping guardrail 23. Two air inlet pipes 24 are provided between the air supply pipe 25 and the inflatable wave-damping guardrail 23. A one-way valve 26 is provided between the air supply pipe 25 and the inflatable component 27. An air release valve 29 is provided at the lower end of the inflatable wave-damping guardrail 23. The two side walls of the inflatable wave-damping guardrail 23 are made of corrugated overlapping wave-damping rubber walls 28.

[0032] The inflation assembly 27 includes an inflation frame 30, an inflator 35 inside the inflation frame 30, nine water wheels 36 fixedly connected to the inflator 35 in a spring-loaded nesting manner on the inflator 35, bearing seats 37 between the two ends of the inflator 35 and the inner wall of the inflation frame 30, a large inflator 38 isolated from water at one end of the bearing seat 37, a small driven gear 31 meshing with the large inflator 38 at the upper end of the large inflator 38, a driven shaft 32 fixedly connected to the driven shaft 31 in a spring-loaded nesting manner on the driven shaft 31, a vacuum pump 34 between the driven shaft 32 and the one-way valve 26, and five suction pipes 33 connected to the air supply pipe 25 at the upper end of the vacuum pump 34.

[0033] A control method for a drawdown zone plant lifting system includes the following steps: when the water level rises to the drawdown zone on the shore, the water pump 6 does not operate; the ecological floating bed 8 uses fixed piles 11 and movable connecting shafts 12 as fixed fulcrums, so that the aquatic plant fixing net 16 with aquatic plants floats on the water surface along with the frame structure composed of the floating bed frame 15 and connecting joints 14; the connecting joints 14 use a two-way structure to connect the floating bed frames 15 at the four corners of the ecological floating bed 8; the connecting joints 14 use a three-way structure to connect the floating bed frames 15 on the four sides of the ecological floating bed 8; and the connecting joints 14 use a four-way structure to connect the other floating bed frames 15 within the ecological floating bed 8. Since the ecological floating bed 8 floats on the water surface, the wave-proof component 10 around the ecological floating bed 8 drives the water wheel 36 through the turbulent water flow or wave impact to drive the large active gear 38 on the active shaft 35 to mesh with the driven small gear 31, so that the driven shaft 32 provides power to the vacuum pump 34, allowing the air intake pipe 33 to pass air through the one-way valve 26, the air supply pipe 25 and the air inlet pipe 24, and finally inflating the inflatable wave-proof guardrail 23, so that the corrugated overlapping wave-proof rubber wall 28 is inflated and straightened. At this time, the air release valve 29 is in the closed state in the water.

[0034] When the water level drops and exposes the drawdown zone on the shore, the ecological floating bed 8 attaches to the drawdown zone. The air release valve 29 releases the air from the inflatable wave-breaking guardrail 23 by breaking the seal of the water body. Water is then transported to the water supply pipe 7 through the inlet pipe 5 of the water pump 6. The aquatic plants on the aquatic plant fixing net 16 are then irrigated through the drip irrigation pipe 9 fixed to the ecological floating bed 8 and the drip nozzle 22. During rainy days, it helps prevent soil erosion in the drawdown zone. On sunny days, the water pump 6 is powered by solar panels 2 and solar batteries 1. On cloudy days, power is supplied directly by the external cable 4.

[0035] In summary, this vegetation enhancement system and its control method for the drawdown zone are characterized by their compact structure, high ecological protection, and high resource utilization. They effectively solve the problem of soil erosion caused by river embankments being easily washed away by river water.
