Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy power generation engineering, in particular to a water conservancy power generation engineering slope protection device. BACKGROUND

[0002] Hydropower is the science and technology of researching technical and economic issues such as engineering construction and production operation for converting water energy into electric energy. The water energy used by hydropower is mainly the potential energy contained in water bodies. In order to realize the conversion of water energy into electric energy, different types of hydropower stations need to be built, and slope protection needs to be set up on both sides of the hydropower station. Slope protection refers to various paving and planting on the slope surface to prevent erosion.

[0003] Water conservancy power generation engineering is usually not built in areas that are dry all year round, and the water yield of the reservoir needs to be ensured to be normal, thereby ensuring the normal operation of water conservancy power generation. The slope protection used by water conservancy power generation engineering mainly includes the ecological design principle, and the slope protection is usually formed by pouring concrete, and uniform planting grooves are left in the profile of the slope protection for planting flowers and plants after filling soil.

[0004] The existing planting groove of the water conservancy power generation engineering slope is usually inclined with the slope surface. When there is heavy rainfall to form flooding, the growth of the water level will cause the soil in the planting groove to be lost due to the erosion of rainwater and water bodies, and at the same time, the planting groove will form water accumulation. Secondly, when there is no flooding, the water level of the water body is usually at the bottom of the slope protection, and the soil in the planting groove will be dry for a long time without contacting the water source, which is not conducive to the growth of plants and needs to be artificially irrigated regularly.

A first piston 51 is disposed inside the first cylinder 5 and slides therewith. The bottom of the first piston 51 is connected to a first connecting rod 52 that slides therewith in a sealed manner with the siphon tube 3. The bottom of the first connecting rod 52 extends to the bottom of the filter screen at the bottom of the corresponding planting trough 23. A cover 53 is disposed on the side wall of the ecological box 2. A second spring 54 is connected to the inner wall of the cover 53. The end of the second spring 54 is connected to a pin 55 that slides therewith with the side wall of the ecological box 2.

[0026] The end of the pin 55 is set as a conical structure, and the inside of the first connecting rod 52 is provided with a matching pin groove located on the outside of the conical structure.

[0027] The water shut-off mechanism includes a second cylinder 6 located at the bottom of the ecological box 2. Inside the second cylinder 6, there is a second piston 61 that slides with it. The top of the second piston 61 is connected to a second connecting rod 62 that slides with the top of the second cylinder 6. The top of the second connecting rod 62 is connected to a pressure block 63 at the bottom of the filter screen of the planting trough 23. A third spring 64 is connected between the pressure block 63 and the second cylinder 6 and sleeved on the outside of the second connecting rod 62. Inside the siphon tube 3, below the second cylinder 6, there is an air bladder 65. The two ends of the air bladder 65 are fixed to the inner wall of the siphon tube 3, and the air bladder 65 is connected to the second cylinder 6 through a pipe. The top of the second cylinder 6 is provided with an air hole.

[0028] Working principle: When using this slope protection device for hydropower projects, firstly, as follows... Figure 1 As shown, the planting trough 23 is located in the ecological box 2 after being filled with soil with a certain moisture and planted. At this time, the weight of the planting trough 23 compresses the first spring 24 to its maximum stroke. The sum of the weight of the planting trough 23 when the soil moisture is low and the elastic force of the first spring 24 is just less than the elastic force of the first spring 24. Furthermore, the outlet 31 and the suction port 32 of the siphon pipe 3 are both located below the water body.

[0029] Then, during the rainfall period, rainwater falls into the ecological box 2, and since the soil has water permeability, the excess rainwater seeps out through the filter screen at the bottom of the planting groove 23 and is transported to the next ecological box 2 through the pipeline and irrigation pipe 21, and finally is discharged into the water body through the drain pipe 22 at the bottom of the bottommost ecological box 2, ensuring the drainage function of the ecological box 2 and preventing water accumulation. At the same time, the ecological box 2 is vertically distributed in a stepwise manner, and under the scouring of rainwater and the scouring of the water body during flooding, soil loss will not occur, compared with the traditional slope-type planting groove body, which has good water and soil loss prevention effect;

[0030] Finally, during a long period of no rainfall, since the water level of the water body is usually below the bottommost ecological box 2 and cannot contact the water body, as the soil humidity in the planting groove 23 gradually decreases, such as Figure 4As shown, the third spring 64 is in a compressed state, and the air bag 65 is in an inflated state, so that the air bag 65 blocks the siphon pipe 3. After the weight of the planting groove 23 is reduced, the ecological box 2 at the bottom is pushed upward by the compressed first spring 24, the third spring 64 pushes the pressing block 63 to move upward to reset, the pressing block 63 drives the second connecting rod 62 to move upward, and the second connecting rod 62 drives the second piston 61 to slide upward. The gas in the air bag 65 can be pumped into the second cylinder 6 through the pipeline. At this time, the air bag 65 is in a contracted state, the siphon pipe 3 is connected, and when the soil humidity of the planting groove 23 in the ecological box 2 at the top reaches the above-mentioned lower weight, 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. The bottom of the tapered surface at the end of the pin rod 55 is pressed by the pin slot at the lower end of the first connecting rod 52, and the pin rod 55 slides to the right and presses the second spring 54. After the end of the pin rod 55 moves out of the pin slot, the planting groove 23 slides a stroke under the action of the first spring 24, and the planting groove 23 drives the first connecting rod 52 to move upward. The first connecting rod 52 drives the first piston 51 to slide upward in the first cylinder 5. Since the one-way valve 4 can only deliver to the irrigation pipe 21, the sliding of the first piston 51 forms a large suction in the siphon pipe 3. The water outlet 31 and the water inlet 32 of the siphon pipe 3 are both located in the water body, and the water inlet 32 is inserted into the water body at a relatively deep depth. A pressure difference is formed between the water outlet 31 and the water inlet 32, and water is sucked into the siphon pipe 3 through the water inlet 32 and discharged into the water body through the water outlet 31 by using the siphon principle. After the water enters the siphon pipe 3, part of the water flow is delivered to the one-way valve 4, the pipeline and the irrigation pipe 21. The irrigation pipe 21 irrigates the planting groove 23 through the irrigation port at the bottom of the irrigation pipe 21. Under the action of drainage, the soil in the planting groove 23 reaches humidity saturation, and the water is sequentially delivered to the ecological box 2 below. The weight of the planting groove 23 in the ecological box 2 at the top is reduced, the first spring 24 is compressed to the maximum stroke, the first piston 51 and the pin rod 55 are reset, the weight of the planting groove 23 in the ecological box 2 in the middle changes vertically without affecting the delivery of water, and until the weight of the planting groove 23 in the ecological box 2 at the bottom is increased to press the pressing block 63. The second piston 61 inflates the air bag 65 through the pipeline to block the siphon pipe 3, and the water inlet 32 stops pumping water, so that the soil in the planting groove 23 is automatically irrigated and watered when the soil is dry, and the normal growth environment of the plants in the planting groove 23 is ensured.
