Description

Technical Field

[0001] This utility model relates to the field of ecological ditch technology, specifically to an ecological ditch for soil and water conservation. Background Technology

[0002] Ditches are a general term for waterways dug for irrigation or drainage. During long-term use, the sand and soil on both sides of ditches are prone to erosion due to water flow. Therefore, in order to carry out soil and water conservation, hardened precast ditches have gradually been used. The main body of these ditches is a precast structure made of metal or other hard materials. When in use, the precast ditches are directly installed on the surface of the excavated waterway, allowing water to flow inside the precast ditches and reducing soil erosion.

[0003] In addition, to further prevent soil and water from being washed away by rainwater from entering the ditch on both sides of the ground or the sloping slope, the ground on both sides of the ditch is usually set up as a green planting area. By planting vegetation on both sides of the ditch, the root system of the vegetation plays a role in soil fixation, forming an ecological ditch and reducing soil erosion.

[0004] Although planting vegetation on both sides of the ditch can reduce soil erosion, the following shortcomings still exist in its use: 1. There is a lack of a safe filtering and blocking mechanism on both sides. During rainy days, large stones and soil clods on the sides are easily washed into the ditch by heavy rain, causing serious blockage and loss, resulting in poor effectiveness; 2. There is a lack of a mechanism for auxiliary personnel to spray water on the planted areas on both sides. Afterwards, personnel need to pull water pipes to move and water the plants, which is inefficient and may cause accidental damage to the plants during the process of moving the water pipes. In view of this, this application proposes a soil and water conservation ecological ditch to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 4 As shown in this embodiment, a soil and water conservation ecological ditch includes:

[0032] Multiple channel bodies 1 are arranged sequentially in the front-to-back direction within pre-dug trenches on the ground. Both sides of channel body 1 are green planting areas 100.

[0033] The U-shaped baffles 101 are in multiple sets, and the top two sides of the channel body 1 are respectively fixedly connected to the bottom of the corresponding U-shaped baffles 101;

[0034] The filter plates 2 are in multiple sets and are movably fitted into the corresponding U-shaped baffles 101;

[0035] The fixing components are in multiple sets and are respectively fixedly connected to the corresponding filter plates 2 and U-shaped baffles 101; the fixing components are used to fix and unlock / disassemble the corresponding filter plates 2.

[0036] The buffer-type rock-blocking assembly consists of multiple sets, each installed on the side of the corresponding U-shaped stop 101 away from the inside of the channel body 1. The buffer-type rock-blocking assembly is used to buffer and block large stones and soil blocks that are accidentally washed away in the green planting area 100 or its slope during rainy weather, so as to avoid direct impact damage to the filter plate 2.

[0037] The spray assembly consists of multiple sets, each fixedly installed on a corresponding U-shaped baffle 101. Two adjacent spray assemblies are connected and fixedly connected by the same hose 405.

[0038] An auxiliary water supply component connects the two spray components fixed at the front. The auxiliary water supply component is used to divert water to the spray components on both sides when personnel connect to the external water pump pipeline. The spray components are used to spray the corresponding green planting area 100 when water is supplied inside them.

[0039] Furthermore, such as Figure 2 and 4 As shown, the fixing assembly includes an L-shaped seat 201, three knob bolts 202 and three nuts 203. The L-shaped seat 201 is fixedly connected to the top of the corresponding filter plate 2 near the inside of the channel body 1. The three nuts 203 are all embedded and fixed to the top of the corresponding U-shaped stop 101 near the inside of the channel body 1. The knob bolts 202 are threaded into the corresponding nuts 203. The L-shaped seat 201 is threaded onto the three knob bolts 202.

[0040] In this embodiment, the top outer side of the L-shaped seat 201 has three threaded holes that are threadedly connected to the corresponding knob bolts 202; the top side of the U-shaped stop 101 near the inside of the channel body 1 has three first fitting grooves that are fixedly connected to the corresponding nuts 203.

[0041] In this implementation scheme, the L-shaped seat 201, three knob bolts 202, and three nuts 203 are used in conjunction. The knob bolts 202 are screwed into the corresponding nuts 203 to fix the L-shaped seat 201, which in turn fixes the filter plate 2. Subsequently, the personnel can rotate the knob bolts 202 in the opposite direction to separate them from the corresponding nuts 203, thereby releasing the fixation of the L-shaped seat 201 and allowing the filter plate 2 to be pushed out from the corresponding U-shaped stop 101 for replacement. This achieves the effect of fixing, unlocking, disassembling, and replacing the filter plate 2, which is convenient for personnel to replace the filter plate 2 when it is damaged in the future.

[0042] Furthermore, such as Figure 2 , 3As shown in Figure 4, the buffer-type stone retaining assembly includes four outer tubes 3, four inner rods 301, four buffer springs 304, a movable seat 302, and multiple stone retaining rods 303. The four outer tubes 3 are equally spaced and fixed to the top of the corresponding U-shaped retaining seat 101 on the side away from the inside of the channel body 1. The two outer tubes 3 on the left and right are both set to a sealing structure at their close ends. The inner rods 301 are slidably sleeved in the corresponding outer tubes 3. The buffer springs 304 are fixedly connected between the end of the corresponding inner rod 301 and the inner wall of the outer tube 3 near the inside of the channel body 1. The movable seat 302 is fixedly connected to the end of the corresponding four inner rods 301 away from the U-shaped retaining seat 101. The multiple stone retaining rods 303 are equally spaced and fixedly connected to the bottom of the corresponding movable seat 302.

[0043] In this embodiment, the top of the side of the U-shaped stop 101 away from the inside of the channel body 1 is provided with four second mounting slots that are fixedly connected to the outside of the corresponding outer pipe 3 respectively.

[0044] In this implementation scheme, through the cooperation of four outer tubes 3, four inner rods 301, four buffer springs 304, a movable seat 302, and multiple retaining rods 303, when large stones and soil are accidentally washed away from the green planting area 100 or its slope during rainy weather, the large stones and soil are blocked and restricted when they reach the corresponding multiple retaining rods 303. Under the impact force, the multiple retaining rods 303 are displaced towards the corresponding U-shaped retaining seat 101, which in turn drives the movable seat 302 to move. The movable seat 302 then drives the retaining rods 303 to move towards the corresponding U-shaped retaining seat 101. The four inner rods 301 slide within the four outer tubes 3 and compress the four buffer springs 304. The elasticity of the buffer springs 304 is used to buffer and deflect the impact force. When the impact shield is released, the inner rods 301 drive the moving seat 302 and the stone-blocking rod 303 to move back to their original positions. This achieves the effect of buffering and blocking large stones and soil that are accidentally washed away in the green planting area 100 or its slope during rainy days, preventing them from directly impacting and damaging the filter plate 2, and improving the application safety and service life of the filter plate 2.

[0045] Furthermore, such as Figure 2 , 3 As shown in Figure 4, the spray assembly includes a horizontal tube 4, which is fixedly installed on the top of the corresponding U-shaped stop 101. The front and rear ends of the horizontal tube 4 are connected and fixed with external threaded tube heads 404. The external threaded tube heads 404 located at the frontmost and rearmost sides are threaded with internal threaded tube caps. The near ends of two adjacent external threaded tube heads 404 located in the middle are connected and fixed to the front and rear ends of the corresponding hoses 405, respectively. The top and bottom of the opposing sides of the two horizontal tubes 4 on the left and right sides are connected and fixed with multiple nozzles 401 at equal intervals. The two nozzles 401 on the top and bottom sides of the two horizontal tubes 4 on the left and right sides are arranged symmetrically and tilted.

[0046] In this implementation scheme, the horizontal pipe 4, nozzle 401, internal threaded pipe cap, and external threaded pipe head 404 work together to supply water into the front horizontal pipe 4. When water is supplied into the front horizontal pipe 4, it is diverted through the hose 405 to the rear horizontal pipe 4. The water is then sprayed outward through multiple nozzles 401 to water the corresponding green planting area 100. This facilitates subsequent watering of the green planting area 100 by auxiliary personnel, effectively avoiding the phenomenon that the green plants are easily damaged when personnel pull the pipe to water in the green planting area 100, and improving the watering efficiency and ease of subsequent personnel.

[0047] Furthermore, such as Figure 1 , 2 As shown in Figures 3 and 4, the auxiliary water supply assembly includes a U-shaped connecting pipe 402 and a water inlet connector 403. The two ends of the U-shaped connecting pipe 402 are respectively connected and fixed to the side of the two horizontal pipes 4 on the front side. The water inlet connector 403 is connected and fixed to the bottom left side of the U-shaped connecting pipe 402.

[0048] In this embodiment, three T-shaped supports are fixedly connected between the bottom of the horizontal tube 4 and the top of the corresponding U-shaped stop 101, which serves to fix and support the horizontal tube 4.

[0049] In this implementation scheme, the U-shaped connecting pipe 402 and the water inlet connector 403 are used together. The water inlet connector 403 is used for personnel to connect to the outlet end of the external water pump through the external connecting hose. When personnel use the external water pump and the pipeline to draw water from the channel 1 for application, the water is supplied into the U-shaped connecting pipe 402 through the external connecting hose connected to the water inlet connector 403, and then diverted to the two horizontal pipes 4 on the front side, so as to assist personnel in water supply and irrigation.

[0050] It should be noted that the filter plate 2, L-shaped seat 201, knob bolt 202, nut 203, outer tube 3, inner rod 301, movable seat 302, stone retaining rod 303, horizontal tube 4, nozzle 401, external threaded pipe head 404, U-shaped connecting pipe 402 and water inlet connector 403 are all preferably made of stainless steel. The stainless steel material has the advantages of high hardness, strong wear and corrosion resistance and good maintenance-free effect, which ensures long-term connection and application stability.

[0051] The usage method of this embodiment is as follows: When using this soil and water conservation ecological ditch, green planting areas 100 are set up on both sides of the ditch body 1 for planting plants to form an ecological ditch. Soil stabilization is achieved through plant rooting, reducing the large amount of soil and water loss into the ditch body 1. When large stones or soil blocks are accidentally washed away in the green planting area 100 or its slope during rainy days, the large stones or soil blocks are blocked and restricted when they reach the corresponding multiple retaining rods 303. Under the impact force, the multiple retaining rods 303 are displaced towards the corresponding U-shaped retaining seat 101, which drives the moving seat 302 to move. The moving seat 302 drives the corresponding four inner rods 301 to slide in the four outer tubes 3, and provides four buffers. The spring 304 is compressed, and the elasticity of the buffer spring 304 is used to buffer and unload the impact force. When the impact shield is released, the inner rod 301 drives the moving seat 302 and the stone retaining rod 303 to move back to their original position. The rainwater passes through multiple stone retaining rods 303, is filtered by the filter plate 2, and flows into the channel body 1. This buffers and blocks large stones and soil that are accidentally washed away in the green planting area 100 or its slope during rainy days, and filters the rainwater out and discharges it into the channel body 1. This avoids the stones and soil from directly impacting and damaging the filter plate 2, improves the application safety and service life of the filter plate 2, and avoids a large number of stones and soil entering the channel body 1, causing serious blockage and loss. This improves the soil and water conservation and the use effect.

[0052] When filter plate 2 is damaged and needs to be replaced after long-term use, the operator can rotate the knob bolt 202 in the opposite direction to separate it from the corresponding nut 203, thereby releasing the L-shaped seat 201. This allows the filter plate 2 to be pushed out of the corresponding U-shaped stop 101. Then, the new filter plate 2 can be pushed into the corresponding U-shaped stop 101. The three knob bolts 202 are then screwed into the threaded holes of the L-shaped seat 201 on the new filter plate 2, and further tightened into the corresponding nuts 203. This allows the filter plate 2 to be fixed by the L-shaped seat 201, enabling the filter plate 2 to be fixed, unlocked, disassembled, and replaced. This facilitates the replacement of the filter plate 2 when it is damaged in the future.

[0053] When it is necessary to spray and water the green planting areas 100 on both sides, the water inlet connector 403 is provided for personnel to connect to the outlet of the external water pump through the external connecting hose. When personnel use the external water pump to draw water from the channel 1 for application, the water is supplied into the U-shaped connecting pipe 402 through the external connecting hose connected to the water inlet connector 403, and then diverted to the two horizontal pipes 4 on the front side. When water is supplied into the horizontal pipes 4 on the front side, the water is diverted to the horizontal pipes 4 on the rear side through the hose 405. The water is sprayed outward through multiple nozzles 401 to spray and water the corresponding green planting areas 100, thereby assisting personnel in spraying and watering the green planting areas 100. This effectively avoids the phenomenon that personnel may damage the green plants by pulling the pipes to water the green planting areas 100, and improves the watering efficiency and ease of subsequent personnel.

[0054] It should also be noted that not all horizontal pipes 4 are supplied with water from a single point. Depending on the number of nozzles 401 and the required spraying pressure, personnel can divide every two or three channels 1 into a unit. That is, an auxiliary water supply component can be set between the two horizontal pipes 4 on the fourth channel 1, and so on. In this way, after spraying water on the outside of the first two or three channels 1, the external water pump can be moved to the fourth channel 1 and connected to the corresponding water inlet connector 403 at its top for water supply and spraying.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
