Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a river ecological slope protection structure. Background Art

[0002] Traditional river slope protection projects mostly use concrete and stone masonry structures. However, these slope protection structures have two major drawbacks: first, they cut off the connection between aquatic and terrestrial organisms in plane, resulting in a lack of transitional areas between the two; second, they cut off the intercommunication between gas, precipitation and bank soil in space, ignoring the existence of biological communities around the river bank and the organic connection between the water ecosystem, which greatly limits the living space of animals, plants and microorganisms in the bank soil, destroying the natural landscape and ecological balance.

[0003] For example, the patent with publication number CN 219298119U discloses a river slope protection masonry and river slope protection, including a placement plate, including a plurality of evenly distributed blocks, the top of the blocks are provided with an upper groove, the bottom of the blocks are provided with a lower groove, the upper groove and the lower groove are matched, and the top side wall of the blocks is provided with two symmetrically arranged first guide grooves. However, the device still has the following problems:

[0004] When used in the rainy season, due to the heavy rain, the slope surface will be directly rained and form water on the slope surface. For light rain weather, the height of the blocks is too high, which is easy to form water accumulation and is not conducive to water flow. For heavy rain weather, the height of the blocks is not enough and it is impossible to achieve water retention;

[0005] When water flows against the slope, it usually carries garbage, which can easily accumulate on the blocks, thus affecting the water retaining effect and being detrimental to slope protection. When there is a lot of garbage, it will flow into the river with the water flow, easily polluting the river. Utility Model Content

[0006] In order to solve the problems existing in the above-mentioned prior art, a river ecological slope protection structure is provided. The device has a reasonable structure and can achieve water stopping in rainy weather, effectively reduce the excessive soil washed away by rainwater, reduce soil erosion, and at the same time intercept garbage, reduce pollution to the river, and achieve ecological slope protection.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] The utility model proposes a river channel ecological slope protection structure, comprising a plurality of filter plates arranged on a slope for filtering water flow, a water retaining plate which moves vertically and blocks the water flow is arranged on the back surface of the filter plate, and a scraper which moves horizontally and cleans the filter plate is arranged on the front surface of the filter plate; the water retaining plate can be lifted up by the buoyancy of water, and when the water retaining plate is lifted up, the scraper can be driven to move horizontally to clean the filter plate.

[0012] Preferably, the slope is provided with a plurality of independently arranged water distribution pipes, one end of the water distribution pipe is connected to the drainage pipe, and the other end of the water distribution pipe is connected to the middle part of the water collection tank.

[0013] Preferably, a stop block is fixedly connected to the upper end of the baffle plate, and a protrusion matched with the stop block is fixedly connected to one side of the water baffle plate. When the water baffle plate drives the protrusion to rise, the baffle plate can be pulled upward by the stop block.

[0014] Preferably, the scraper is connected with a slide rod, the filter plate is provided with a slide groove arranged in a horizontal direction, the slide rod is slidably arranged in the slide groove, and one end of the scraper close to the filter plate is detachably connected with a brush.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model is provided with a water retaining plate which can move vertically to achieve water retaining. In rainy weather, as the amount of rainfall increases, the water retaining plate can be driven to rise so that the height of the water retaining plate can be adapted to the amount of rainfall. The utility model has a reasonable structure and can better achieve water stopping in rainy weather, effectively reducing the amount of soil washed away by rainwater and reducing soil erosion.

[0020] 2. The utility model is provided with a water diversion pipe.

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Embodiment 1

[0032] like Figure 1-Figure 5 As shown, this embodiment proposes a river ecological slope protection structure, including a plurality of filter plates 3 arranged on a slope 1 for water filtering, the filter plate 3 is detachably connected with a filter screen 18, and the filter screen 18 can be detachably connected to the filter plate 3 by means of bolts. When the filter screen 18 is used for too long, it can be disassembled by bolts to achieve replacement of the filter screen 18.

[0033] The filter 18 can intercept garbage in the water flow. The aperture of the filter 18 is adapted to the environment in which the device is used. For rivers with high sediment content, a filter 18 with a larger aperture can be used to effectively reduce the blockage of the filter 18. By selecting an aperture of appropriate size, garbage can be intercepted without affecting water flow.

[0034] The back surface of the filter plate 3 is provided with a water baffle 6 which moves vertically and blocks the water flow, and the front surface of the filter plate 3 is provided with a scraper 8 which moves horizontally and cleans the filter plate 3. The scraper 8 is used to clean the surface of the filter plate 3, and the water baffle 6 is used to block the water passing through the filter plate 3.

[0035] The water retaining plate 6 can rise upward due to the buoyancy of water. When the rainfall increases, the height of the water retaining plate 6 will rise higher. The height of the water retaining plate 6 is adapted to the rainfall, so that the water flow will not be affected due to the height being too high, and the water will not be unable to be blocked due to the height being too low.

[0036] When the water baffle plate 6 rises upward, the scraper 8 can be driven to move horizontally through the corresponding transmission mechanism to clean the filter plate 3. The horizontal movement of the scraper 8 can be coordinated with the vertical movement of the water baffle plate 6. The transmission mechanism can be a gear rack or other structure to convert the vertical movement of the water baffle plate 6 into the horizontal movement of the scraper 8.

[0037] The slope body 1 is provided with a plurality of independently arranged water collecting grooves 9, in which the water retaining plates 6 are slidably arranged, and the water retaining plates 6 can slide vertically in the water collecting grooves 9. The number of the water collecting grooves 9 is the same as the number of the water retaining plates 6. The water collecting grooves 9 can be used to collect water, thereby driving the water retaining plates 6 located therein to rise under the action of buoyancy.

[0038] The slope 1 is provided with a plurality of drainage pipes 7 which are interconnected. A water inlet 20 is provided at the bottom of the water collecting trough 9. The water inlet 20 is connected to the drainage pipe 7. The number of drainage pipes 7 is the same as the number of water collecting troughs 9. The plurality of water collecting troughs 9 are independently arranged. The plurality of drainage pipes 7 are interconnected. The drainage pipe 7 located at the bottom is connected to the river channel. Therefore, the water in the water collecting trough 9 can eventually flow into the river channel.

[0039] The water collecting trough 9 is slidably connected with a connecting rod 10 that moves in the vertical direction. The connecting rod 10 can only slide in the vertical direction. The bottom end of the connecting rod 10 is fixedly connected with a baffle 12 that can block the water inlet 20. The baffle 12 is provided with a water hole 14 for water to flow through.

[0040] In the initial state, under the action of gravity, the baffle 12 and the bottom end of the sump 9 are in contact, the baffle 12 can block the water inlet 20, and the water in the sump 9 can flow into the drain pipe 7 through the water hole 14. The size of the water hole 14 is suitable enough to facilitate water discharge. Only when the rainfall is greater than the water discharge of the water hole 14 will the baffle 6 rise. Therefore, the baffle 6 will not affect the normal water flow, and will only rise when it rains to achieve water blocking.

[0041] In rainy weather, as the rainfall increases, the water retaining plate 6 can be driven to rise, so that the height of the water retaining plate 6 can be adapted to the rainfall. The structure is reasonable, and in rainy weather, water can be stopped better, effectively reducing the erosion of excessive soil by rainwater and reducing soil erosion.

[0042] The slope is provided with a plurality of independently arranged water distribution pipes 13, one end of which is connected to the drainage pipe 7, and the other end of which is connected to the middle part of the water collecting tank 9. The number of the water distribution pipes 13 is the same as the number of the water collecting tanks 9, and each water collecting tank 9 has a corresponding water distribution pipe 13.

[0043] A stop block 11 is fixedly connected to the upper end of the baffle 12, and a protrusion 17 that cooperates with the stop block 11 is fixedly connected to one side of the water baffle 6. When the water baffle 6 drives the protrusion 17 to rise, the baffle 12 can be pulled upward by the stop block 11. When the baffle 12 moves upward, the baffle 12 no longer blocks the water inlet 20, which can effectively increase the amount of water entering the drain pipe 7 from the sump 9.

[0044] As the amount of rainfall increases, the water retaining plate 6 can also drive the baffle 12 to rise, further increasing the water output, so that part of the water can be discharged from the drain pipe 7. At this time, the increase in the water inlet 20 increases the water output. At the same time, part of the water can flow out through the water diversion pipe 13, which can play a role in water diversion, and this part of the water can directly flow into the river channel to reduce soil erosion.

[0045] Since the rainfall is unstable, the setting of the water distribution pipe 13 also increases the water output. Therefore, only when the rainfall reaches a sufficient intensity will the water baffle 6 rise further. When the rainfall fluctuates, the water baffle 6 will not rise until the rainfall reaches a certain level, that is, the water inflow is greater than the water output of the water distribution pipe 13 and the water hole 14 at the same time, so that the water baffle 6 will not affect the normal passage of water flow, which is conducive to drainage.

[0046] A collection box 2 for collecting garbage is provided on one side of the filter plate 3. When the scraper 8 cleans the filter plate 3, the garbage can be pushed into the collection box 2. The collection box 2 is an open structure at one end, and the other end of the collection box 2 is lower than the open end, so it is convenient for garbage to enter the collection box 2.

[0047] A limit block is set in the water collecting tank 9, and the limit block is used to limit the movement height of the water baffle 6. When the water baffle 6 rises and contacts the limit block, the water baffle 6 cannot continue to rise under the action of the limit block. At this time, the height of the water baffle 6 can drive the baffle 12 to rise through the connecting rod 10, so that the water inlet 20 is fully opened.

[0048] A planting area 19 is provided between any adjacent filter plates 3. Plants can be planted in the planting area 19 according to actual needs. The plants can play a role in reducing soil erosion. For example, the following plants can be planted:

[0049] Willow: Willow has a well-developed root system that can effectively consolidate the soil and absorb water, and is very effective in curbing soil erosion on slopes.

[0050] Cineraria: Cineraria has a dense root system that can hold the soil tightly, while its lush leaves can also cover and protect the soil.

[0051] Green beans: The root system of green beans is well developed and has a network structure, which can effectively prevent soil erosion and provide organic matter to the soil during the growth process.

[0052] Moso bamboo: Moso bamboo is a tall bamboo plant with a well-developed root system that can stabilize the soil, resist soil erosion, and has a good soil and water conservation effect.

[0053] Yew: Yew is a common coniferous tree whose root system can effectively bind the soil and form a strong protective layer to reduce soil erosion.

[0054] When selecting suitable plants, local climate, soil conditions and project requirements should also be considered to ensure that the selected plants can achieve the expected soil and water conservation effects. Embodiment 2

[0055] Reference Figure 6, other structures are the same as those in the first embodiment, except that, in this embodiment, consideration is given to how to better drive the scraper to move.

[0056] The scraper 8 and the filter plate 3 are slidably connected, the scraper 8 is connected with a slide rod 5, the filter plate 3 is provided with a slide groove 4 arranged in the horizontal direction, the slide rod 5 is slidably arranged in the slide groove 4, and the slide groove 4 limits and guides the movement of the slide rod 5. The slide rod 5 can only move along the length direction of the slide groove 4, thereby ensuring that the scraper 8 can only move in the horizontal direction to achieve the cleaning of the scraper 8.

[0057] One end of the scraper 8 close to the filter plate 6 is detachably connected with a brush, which can clean the surface of the scraper 8. The length of the chute 4 is greater than the length of the filter screen 18, so that the scraper 8 can sweep the garbage into the collection box 2.

[0058] The water baffle plate 6 is provided with a guide groove 15 arranged in an inclined direction, and an opening 16 for the slide bar 5 to slide into is provided at the higher end of the guide groove 15. When the water baffle plate 6 rises, the slide bar 5 can slide into the opening 16. Then, as the water baffle plate 6 continues to rise, the slide bar 5 slides in the guide groove 15, so that when the water baffle plate 6 rises, it can drive the scraper 8 to move in the horizontal direction to achieve the cleaning of the filter screen 18.

[0059] The specific working process is as follows: in rainy weather, rainwater enters the water collecting trough 9, and the water in the water collecting trough 9 flows into the drain pipe 7 through the water hole 14. As the rainfall increases, when the water inflow is greater than the water outflow, the buoyancy of the water drives the water retaining plate 6 to rise to achieve water retaining.

[0060] As the rainfall increases further, when the water level in the sump 9 is higher than the water diversion pipe 13, excess water can flow from the water diversion pipe 13 into the drain pipe 7, thereby further increasing the water output. If the rainfall increases further and the water inflow is greater than the water output of the water hole 14 and the water diversion pipe 13, the water retaining plate 6 rises further to block water. At the same time, the water retaining plate 6 can drive the baffle 12 to rise, so that the water inlet 20 is fully opened. At this time, diversion can be achieved, and part of the water can be discharged through the drain pipe 7, reducing the scouring of the slope 1.

[0061] During the rising process of the water retaining plate 6 , the slide bar 5 slides into the guide groove 15 through the opening 16 . As the slide bar 5 slides in the guide groove 15 , the scraper 8 can be driven to move in the horizontal direction, thereby cleaning the filter plate 3 .

[0062] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
