Description

Technical Field

[0001] The invention relates to the technical field of hydropower generation engineering, in particular to a slope protection device for hydropower generation engineering. Background Art

[0002] Hydropower generation is a science and technology that studies the technical and economic issues of engineering construction and production operation that converts water energy into electrical energy. The water energy used in hydropower generation is mainly the potential energy contained in the water body. In order to realize the conversion of water energy into electrical energy, different types of hydropower stations need to be built. Slope protection needs to be set up on both sides of the hydropower station. Slope protection refers to the general term for various paving and planting on the slope surface to prevent the slope from being eroded.

[0003] Hydropower projects are usually not built in areas with perennial drought. It is necessary to ensure the normal water flow of the reservoir to ensure the normal operation of hydropower generation. The characteristics of the slope protection used in hydropower projects mainly include ecological design principles. The slope protection is usually formed by pouring concrete. At the same time, uniform planting grooves are left in the profile of the slope protection, which are used to plant flowers and plants after filling with soil.

[0004] The existing slope protection planting troughs of hydropower generation projects are usually tilted along with the slope. When the rainfall is heavy and floods occur, as the water level rises, the erosion of rainwater and water bodies will cause the loss of soil in the planting troughs, and at the same time cause water accumulation in the planting troughs. Secondly, when no floods occur, the water level of the water body is usually at the bottom of the slope protection. The planting troughs have not been in contact with water for a long time, which will cause the soil to be dry, which is not conducive to the growth of plants and requires regular manual watering. Summary of the invention

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a slope protection device for a hydropower generation project, comprising a concrete slope body, wherein eco-boxes are arranged vertically upward at equal intervals on the slope of the concrete slope body, and irrigation pipes are arranged at the upper ends of the eco-boxes, and planting troughs that slide with the eco-boxes are arranged inside the eco-boxes, and a first spring is connected between the bottom of the planting trough and the eco-boxes, a siphon is arranged on the concrete slope body, a one-way valve is installed on the outer wall of the siphon located above the eco-box near the top of the slope, and the one-way valve is connected to the irrigation pipe of the eco-box through a pipeline, a water absorption mechanism is arranged between the eco-box near the top of the slope of the concrete slope and the siphon, and a water cut-off mechanism is arranged inside the eco-box near the bottom of the slope of the concrete slope.

[0007] Preferably, the bottom of the eco-box is connected to the irrigation pipe at the upper end of the adjacent eco-box through a pipeline, and irrigation ports are arranged at equal intervals at the bottom of the irrigation pipe. A drainage pipe that runs through the outer wall of the concrete slope is arranged at the bottom of the eco-box near the bottom end of the slope of the concrete slope, and a filter is arranged at the bottom of the planting trough.

[0008] Preferably, the siphon tube is configured as a U-shaped structure, and one end of the siphon tube extends out of the side wall of the concrete slope and is located below the eco-box, and the other end of the siphon tube extends to the side wall of the concrete slope and is located above the eco-box, one end of the siphon tube is provided with a vertically downward water outlet, and the other end of the siphon tube is provided with a vertically downward water suction port, and the end of the water outlet is located above the end of the water suction port.

[0009] Preferably, the water absorption mechanism includes a first cylinder body arranged on the outer wall of the siphon tube, the top of the first cylinder body is arranged as an open structure, the interior of the first cylinder body is arranged with a first piston slidably matched therewith, the bottom of the first piston is connected to a first connecting rod slidably matched with the siphon tube seal, the bottom of the first connecting rod extends to the bottom of the filter screen at the bottom of the corresponding planting trough, the side wall of the eco-box is provided with a cover body, the inner wall of the cover body is connected to a second spring, and the end of the second spring is connected to a pin rod slidably matched with the side wall of the eco-box.

[0010] Preferably, the end of the pin rod is arranged as a conical structure, and a matching pin groove is arranged inside the first connecting rod and outside the conical structure.

[0011] Preferably, the water cut-off mechanism includes a second cylinder arranged at the bottom of the eco-box, a second piston slidably matched with the second cylinder is arranged inside the second cylinder, the top of the second piston is connected to a second connecting rod slidably matched with the top of the second cylinder, the top of the second connecting rod is located at the bottom of the filter screen of the planting trough and is connected to a pressure block, a third spring sleeved on the outside of the second connecting rod is connected between the pressure block and the second cylinder, an air bag is arranged inside the siphon tube below the second cylinder, both ends of the air bag are respectively fixed to the inner wall of the siphon tube, and the air bag and the second cylinder are connected by a pipeline, and an air hole is arranged on the top of the second cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, during the rainy period, rainwater falls into the eco-box. Since the soil is permeable, excess rainwater seeps out through the filter screen at the bottom of the planting trough and is transported to the next eco-box through the pipeline and the irrigation pipe, and finally discharged into the water body through the drainage pipe at the bottom of the lowest eco-box, thereby ensuring the drainage function in the eco-box and preventing water accumulation. In the present invention, when the water level of the water body increases higher than the eco-box during floods, the eco-box is vertically stepped upward, and no soil loss will be caused by the scouring of rainwater and the scouring of water bodies during floods. Compared with the traditional slope-type planting trough, the present invention has a good effect of preventing and controlling soil and water loss. According to the present invention, when there is no rainfall for a long time, as the soil moisture in the planting trough gradually decreases, the siphon tube is connected under the action of the water cut-off mechanism, and when the soil moisture in the planting trough in the topmost eco-box reaches the above-mentioned lower weight, the planting trough slides up a certain distance under the action of the water absorption mechanism, so that a larger suction force is formed in the siphon tube, wherein the water outlet and the water suction port of the siphon tube are both located in the water body, and the water suction port is inserted into the water body to a greater depth, a pressure difference is formed between the water outlet and the water suction port, and the water body is sucked into the siphon tube through the water suction port and discharged into the water body through the water outlet by utilizing the siphon principle. After the water enters the siphon, part of the water will flow to the one-way valve, pipeline and irrigation pipe, and irrigate the planting trough through the irrigation port at the bottom of the irrigation pipe. Under the drainage effect, after the soil in the planting trough reaches moisture saturation, the water is transported to the ecological box below in turn until the weight of the planting trough in the bottom ecological box increases and presses the pressure block. The second piston inflates the air bag through the pipeline to block the siphon, and the water intake port starts to stop pumping water, so that when the soil in the planting trough is relatively dry, the soil is automatically irrigated and replenished with water. No electric control is required, ensuring the normal growth environment of the plants in the planting trough. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Working principle: When using the slope protection device for hydropower projects, first, Figure 1 As shown, the position of the planting trough 23 in the eco-box 2 is after the soil with a certain humidity is filled and the plants are planted, and the weight of the planting trough 23 at this time compresses the first spring 24 to the maximum stroke, and the sum of the weight of the soil with low humidity in the planting trough 23 and the elastic force of the first spring 24 is just less than the elastic force of the first spring 24, and secondly, the water outlet 31 and the water intake 32 of the siphon 3 are both located under the water body; Then, during the rainy period, rainwater falls into the eco-box 2. Since the soil is permeable, excess rainwater seeps out through the filter screen at the bottom of the planting trough 23 and is transported to the next eco-box 2 through the pipeline and irrigation pipe 21, and finally discharged into the water body through the drainage pipe 22 at the bottom of the bottom eco-box 2, thereby ensuring the drainage function in the eco-box 2 and preventing water accumulation. At the same time, the eco-boxes 2 are vertically stepped upward, and will not cause soil loss under the scouring of rainwater and the scouring of water bodies during floods. Compared with the traditional slope-type planting trough, it has a good effect of preventing and controlling soil and water loss. Finally, when there is no rainfall for a long time, since the water level is usually below the bottom ecological box 2 and cannot contact the water body, as the soil moisture in the planting trough 23 gradually decreases, Figure 4As shown, the third spring 64 is in a compressed state, and the airbag 65 is in an expanded state, so that the airbag 65 blocks the siphon 3. After the weight of the planting trough 23 is reduced, it is located in the bottom ecological box 2, and the compressed first spring 24 pushes the planting trough 23 to slide upward, and the third spring 64 pushes the pressure block 63 to move up and reset, and the pressure block 63 drives the second connecting rod 62 to move up, and the second connecting rod 62 drives the second piston 61 to slide up, and the gas of the airbag 65 can be pumped into the second cylinder 6 through the pipeline. The airbag 65 is in a contracted state at this time, and the siphon 3 is turned on. When the soil moisture in the planting trough 23 in the top ecological box 2 is When the weight reaches the lower level mentioned above, the elastic force of the first spring 24 can push the planting groove 23, and the planting groove 23 drives the first connecting rod 52 to move upward, and the pin groove at the lower end of the first connecting rod 52 squeezes the bottom of the conical surface of the end of the pin rod 55, and the pin rod 55 slides to the right and squeezes the second spring 54. After the end of the pin rod 55 moves out of the pin groove, under the action of the first spring 24, the planting groove 23 slides up a stroke, and the planting groove 23 drives the first connecting rod 52 to move upward, and the first connecting rod 52 drives the first piston 51 to slide up in the first cylinder 5. Since the one-way valve 4 can only be delivered to the irrigation pipe 21, the first piston 51 The sliding of the siphon tube 3 forms a large suction force, wherein the water outlet 31 and the water inlet 32 ​​of the siphon tube 3 are both located in the water body, and the water inlet 32 ​​is inserted into the water body to a greater depth, and a pressure difference is formed between the water outlet 31 and the water inlet 32. By utilizing the siphon principle, the water body is sucked into the siphon tube 3 through the water inlet 32 ​​and discharged into the water body through the water outlet 31. After the water body enters the siphon tube 3, part of the water flow will lead to the one-way valve 4, the pipeline and the irrigation pipe 21, and the irrigation port at the bottom of the irrigation pipe 21 is used to irrigate the planting trough 23. Under the drainage effect, after the soil in the planting trough 23 reaches saturation with moisture, the water body flows to the ecological system below in sequence. The water is transported in the box 2. The weight of the planting trough 23 in the top ecological box 2 slides down with the watering to compress the first spring 24 to the maximum stroke, and the first piston 51 and the pin rod 55 are both reset. The weight change of the planting trough 23 in the middle ecological box 2 will not affect the water transportation when it moves longitudinally, until the weight of the planting trough 23 in the bottom ecological box 2 increases and presses the pressure block 63. The second piston 61 inflates the air bag 65 through the pipeline to block the siphon tube 3, and the water suction port 32 starts to stop pumping water, so that when the soil in the planting trough 23 is relatively dry, the soil is automatically irrigated and replenished with water to ensure the normal growth environment of the plants in the planting trough 23.
