Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of drainage ditch, specifically relates to a water and soil conservation ecological drainage ditch. BACKGROUND

[0002] In today's society, with the acceleration of urbanization and the continuous expansion of agricultural activities, water and soil conservation has become an important problem to be solved in environmental protection and sustainable development. The traditional drainage ditch design has significant shortcomings in dealing with rainwater discharge and water and soil conservation.

[0003] The drainage ditch used in the past often has a single and simple structure. Most of them are only a simple trench, which lacks a carefully designed layered structure and filtering device inside. Then the water is discharged to the drainage channel or river through the water permeable pipe, but when the rainfall is at a normal level, they can barely undertake the drainage task, but once they encounter extreme heavy rain or long-lasting heavy rain, their drainage speed often cannot keep up with the speed of rainwater collection. This is because the drainage channel size of the traditional drainage ditch is fixed, and it lacks a flexible adjustment mechanism to automatically adjust the drainage capacity according to the actual rainfall.

[0004] When the flow of rainwater exceeds the normal drainage capacity of the drainage ditch, due to the lack of effective pressure regulation and additional drainage channel opening mechanism, the water pressure inside the drainage ditch will rise rapidly. This rapidly increasing water pressure may cause serious damage to the structure of the drainage ditch, such as causing the collapse of the ditch wall and the rupture of the ditch bottom; on the other hand, the high water pressure may also cause the water to flow in the opposite direction, causing the surrounding soil to be excessively soaked, leading to soil erosion, land subsidence and other serious problems, causing great damage to the surrounding ecological environment and infrastructure.

[0005] Therefore, we propose a water and soil conservation ecological drainage ditch. The device has a unique reinforced drainage design, i.e. through the water pressure to push the sealing conical block to open the additional drainage channel, greatly improving the drainage capacity of the drainage ditch, avoiding the occurrence of water accumulation, reducing the risk of various disasters that may be caused by water accumulation, and better maintaining the stability of the surrounding ecological environment.

[0015] The utility model achieves the following technical effects:

[0016] When rainwater or surface water flows through the drain body, it will first enter the groove body, and the rainwater first contacts the filling layer in the groove body, which forms a natural filtering barrier, larger impurities and particles are blocked on the surface of the filling layer, and smaller impurities can be partially intercepted, and the presence of the filling layer increases the resistance of the water flow, so that the water flow speed is significantly slowed down, not only the direct impact force of the water flow on the soil is reduced, the risk of soil erosion is reduced, but also the precipitation of impurities in the water flow is helped, after the preliminary filtration and speed reduction of the filling layer, the water flow continues to flow downward, enters the water inlet shell inside the drainage layer, and the plurality of water permeable pipes arranged in the water inlet shell provide the main discharge channel for the water flow, under normal rainfall, rainwater can flow relatively smoothly through the water permeable pipe and be discharged, however, in the case that the rainfall is too large and exceeds the normal drainage capacity of the water permeable pipe, rainwater begins to accumulate in the water inlet shell, and as the rainwater continues to accumulate, the water pressure in the water inlet shell gradually increases, at this time, the bottom water pressure directly acts on the sealing conical block, the shape of the sealing conical block matches the conical hole, when the water pressure reaches a certain degree, the strong pressure overcomes the elastic force of the elastic adjusting assembly, the elastic adjusting assembly can be composed of elastic components such as springs and is compressed under the action of pressure, and the sealing conical block is displaced in the conical hole, so that the originally sealed conical hole is opened, in this way, the excess rainwater accumulated in the water inlet shell can flow into the reinforced drainage cavity connected with the conical hole, and the reinforced drainage cavity provides additional storage space and discharge path for the excess rainwater, thereby effectively avoiding problems such as waterlogging and excessive soil soaking caused by rainwater accumulation, and ensuring the effect of water and soil conservation and the stability of the surrounding environment.

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, the specific technical solution adopted in this utility model is as follows: a water and soil conservation ecological drainage ditch includes a drainage ditch body 1, a ditch body 2 is constructed on the drainage ditch body 1, and a filling layer 3 and a drainage layer are arranged sequentially from top to bottom in the ditch body 2. The drainage layer includes a water inlet shell 4 connected to the inner wall of the ditch body 2 and multiple water permeable pipes 5 arranged inside the water inlet shell 4, and multiple through holes are opened at the bottom of the water inlet shell 4.

[0025] The drainage ditch body 1 has a reinforced drainage cavity 6 and multiple conical holes 7. The reinforced drainage cavity 6, multiple conical holes 7 and multiple through holes are interconnected. An elastic adjustment component is provided on the bottom inner wall of the reinforced drainage cavity 6. A sealing conical block 8 located inside the conical hole 7 is installed on the elastic adjustment component.

[0026] The filling layer 3 includes a sand layer 9, a gravel layer 10, and a filter layer 11. The sand layer 9, gravel layer 10, and filter layer 11 prevent larger impurities and particles from being trapped on the surface of the filling layer 3, while smaller impurities may be partially retained. Simultaneously, the presence of the filling layer 3 increases the resistance to water flow, significantly slowing down the water flow velocity.

[0027] Meanwhile, the top of the water inlet housing 4 has multiple water permeable holes, through which filtered water can enter the interior of the water permeable housing.

[0028] The tapered hole 7 is narrow at the top and wide at the bottom. This design allows water to flow into the sealed tapered block 8 when it moves downwards, creating a channel between the sealed tapered block 8 and the inner wall of the tapered hole 7.

[0029] The elastic adjusting assembly comprises a hollow plate 12 arranged on the inner wall of the bottom of the reinforced drainage cavity 6, a spring 13 arranged inside the hollow plate 12, a piston plate 14 arranged on the top of the spring 13, a movable plate 15 arranged on the top of the piston plate 14, and the movable plate 15 penetrating through the hollow plate 12 and being connected with the sealing conical block 8. When the water pressure and mass inside the water inlet shell 4 exceed the elastic potential energy of the spring 13, the sealing conical block 8 drives the movable plate 15 to press the piston plate 14, so that the conical hole 7 is opened to allow water to enter the reinforced drainage cavity 6.

[0030] The drainage ditch body 1 is provided with a drainage opening 16 in communication with the reinforced drainage cavity 6, so that water is discharged through the drainage opening 16.

[0031] The working principle of the utility model is as follows: when rainwater or surface water flows through the drainage ditch body 1, it will first enter the groove body 2. The rainwater first contacts the filling layer 3 in the groove body 2. These materials form a natural filtering barrier. Larger impurities and particles are blocked on the surface of the filling layer 3. Smaller impurities may be partially intercepted. At the same time, the presence of the filling layer 3 increases the resistance of the water flow, significantly slowing down the water flow. This deceleration not only reduces the direct impact of the water flow on the soil, reducing the risk of soil erosion, but also helps the impurities to settle in the water flow. After preliminary filtration and deceleration by the filling layer 3, the water flow continues to flow downward into the water inlet shell 4 of the drainage layer. The multiple water permeable pipes 5 arranged in the water inlet shell 4 provide the main discharge channel for the water flow. Under normal rainfall, rainwater can flow relatively smoothly through the water permeable pipes 5 and be discharged. However, when the rainfall is too heavy and exceeds the normal drainage capacity of the water permeable pipes 5, rainwater begins to accumulate in the water inlet shell 4. As the rainwater continues to accumulate, the water pressure in the water inlet shell 4 gradually increases. At this time, the water pressure at the bottom directly acts on the sealing conical block 8. The shape of the sealing conical block 8 matches the conical hole 7. When the water pressure reaches a certain level, the strong pressure overcomes the elastic force of the elastic adjusting assembly, which may be composed of a spring 13 and other elastic components, which is compressed under pressure. The sealing conical block 8 is displaced in the conical hole 7. The originally sealed conical hole 7 is opened. In this way, the excess rainwater accumulated in the water inlet shell 4 can quickly flow into the reinforced drainage cavity 6 through the opened conical hole 7. The reinforced drainage cavity 6 provides additional storage space and discharge path for the excess rainwater, thereby effectively avoiding problems such as waterlogging and excessive soil soaking that may be caused by rainwater accumulation, ensuring the effectiveness of water and soil conservation and the stability of the surrounding environment. The device improves the drainage capacity of the drainage ditch through the unique reinforced drainage design, i.e. opening the additional drainage channel by pushing the sealing conical block 8 with water pressure, thereby avoiding the occurrence of waterlogging and reducing the risk of various disasters that may be caused by waterlogging, while better maintaining the stability of the surrounding ecological environment.

[0032] The above only is the preferred embodiment of the utility model, it should be pointed out, for ordinary skilled person in the art, without departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be considered the protection scope of the utility model.The structure, device and operating method not specifically described and explained in the utility model, are implemented according to conventional means in the art, unless specifically described and limited.
