Description

Technical Field

[0001] This utility model relates to the field of drainage ditch technology, and in particular to a drainage ditch for soil and water conservation. Background Technology

[0002] Currently, soil erosion is a pressing environmental problem that needs to be addressed in agricultural and forestry production, highway and railway construction, and ecological restoration of mining areas. The collection and erosion of surface runoff are among the main causes of soil erosion. Therefore, constructing drainage ditches to guide and discharge surface runoff in an orderly manner is the most widely used and effective soil and water conservation engineering measure. The structural performance of drainage ditches directly affects their service life and their effectiveness in protecting slope soil.

[0003] Regarding the aforementioned aspects, some applications of drainage ditches are disclosed in the prior art. For example, in many projects, ditches are typically formed using precast concrete components or on-site casting. These ditches often have trapezoidal or rectangular cross-sections, and their main function is to collect surface water through smooth inner walls and utilize gravitational potential energy to rapidly transport it to a designated downstream location, preventing water from overflowing onto slopes or roadbeds. For segmented precast ditches, the connections typically involve pre-reserved overlap structures at the ends. After manual alignment on-site, the joints are sealed with cement mortar or mechanically fixed using bolts or other fasteners, thereby connecting the independent ditch segments into a continuous whole.

[0004] However, the inherent limitations of existing drainage ditch designs are gradually becoming apparent. Firstly, their structural function is relatively singular, overemphasizing drainage efficiency. This often results in extremely high water flow velocity within the ditch. The powerful kinetic energy of this water not only erodes the bottom and sidewalls of the ditch, causing structural damage, but also creates new scouring points for downstream rivers or farmland. Existing designs generally lack proactive mechanisms to reduce the energy of the flowing water.

[0005] Secondly, most of the runoff is treated as "wastewater" that needs to be drained away quickly and is transported away directly. There is a lack of design elements to allow some of the water to return to the soil and replenish groundwater, resulting in a waste of water resources.

[0006] Furthermore, the methods for handling floating debris and sediment are rather passive. Traditional grilles or filters have fixed sizes, which cannot cope with the changing debris conditions in different seasons and environments. This results in them either failing to effectively intercept small debris or quickly becoming clogged when faced with large amounts of fallen leaves, thus hindering normal drainage.

[0007] Finally, the connection methods between existing ditch segments are relatively fixed. Mortar masonry is not only slow to construct and has a long curing period, but it is also a permanent connection, which brings great inconvenience to later maintenance, replacement, or line adjustment. It often requires the destructive demolition of the original structure, which is time-consuming and labor-intensive. On the other hand, bolted connections are complicated and require a high level of skill from the installers.

[0008] To address the above problems, a drainage ditch for soil and water conservation is proposed. Utility Model Content

[0009] To overcome the above shortcomings, this utility model provides a drainage ditch for soil and water conservation, aiming to solve the problems of existing drainage ditches for soil and water conservation having a single structural function, lacking energy dissipation and infiltration structure, poor adaptability to debris, and complex connection and installation between segments.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a drainage ditch for soil and water conservation, comprising a channel, a baffle plate being provided at the top of the channel, an adjustment assembly being provided inside the baffle plate, the adjustment assembly comprising an inner grid plate, an inner groove being formed inside the baffle plate, the inner grid plate being slidably connected inside the inner groove, limiting plates being fixedly connected to both ends of the inner grid plate, two limiting plates being slidably connected to the inner sides of the baffle plate, and a lever being fixedly connected to both sides of the top of the limiting plate, two insert blocks being symmetrically arranged on one side of the channel, and two insertion holes being symmetrically formed on the other side of the channel, the insert blocks being inserted into the insertion holes, and a locking assembly being provided inside the insert blocks.

[0011] As a further description of the above technical solution: The snap-fit ​​assembly includes a snap-fit ​​block, which is slidably connected inside the insert block. A slider is fixedly connected to the middle of the snap-fit ​​block, and a pressure spring is sleeved on the outer side of the snap-fit ​​block. A slide rod is fixedly connected inside the first insertion hole, and a buffer spring is sleeved on one side of the slide rod. A stop block is slidably connected to the outer side of the slide rod.

[0012] As a further description of the above technical solution: The top of the pressure spring is fixedly connected to the bottom of the slider, and the bottom of the pressure spring is fixedly connected to the inside of the insert.

[0013] As a further description of the above technical solution: One end of the buffer spring is fixedly connected to the outside of the abutment block, and the other end of the buffer spring is fixedly connected to the inside side of the insertion hole.

[0014] As a further description of the above technical solution: The bottom of the card block and the bottom of the abutment block are both set as slopes, and the top of the card block abuts against the bottom of the abutment block.

[0015] As a further description of the above technical solution: The bottom sides of the barrier plate are provided with side sliding plates, and the top sides of the ditch are provided with side sliding grooves, and the side sliding plates are slidably connected to the inside of the side sliding grooves.

[0016] As a further description of the above technical solution: The bottom wall of the ditch has a second insertion hole on one side and a central insertion block on the other side of the bottom wall of the ditch. The central insertion block is inserted into the second insertion hole.

[0017] As a further description of the above technical solution: Side drainage channels are provided on both sides of the ditch, and multiple energy dissipation sills are provided on the inner bottom wall of the ditch, with bottom permeation holes provided between two energy dissipation sills.

[0018] This utility model has the following beneficial effects: 1. In this utility model, multiple drainage channels are opened on the side wall of the ditch, and multiple energy dissipation sills and bottom infiltration holes are installed inside to drastically reduce the energy of the water flow, prevent erosion, and facilitate water backflow; and an adjustment component is set in the barrier plate at the top of the ditch. By adjusting the inner sill plate inside, the space for debris to pass through the barrier plate can be changed, effectively blocking impurities entering the ditch and preventing the accumulation of debris from affecting the normal flow of water in the ditch.

[0019] 2. In this utility model, to facilitate the installation of the ditch, insert blocks and insertion holes are respectively set on both sides of the ditch, and snap-fit ​​components are set in the insert blocks and insertion holes. The snap-fit ​​block set inside the insert block can retract into the insert block after entering the insertion hole under the action of the slider and the pressure spring, and extend under the action of the pressure spring to snap the snap-fit ​​block into the insertion hole. When disassembly is required, the insert block is inserted further inward, and the snap-fit ​​block retracts again under the action of the abutment block. When the snap-fit ​​block moves outward, it can drive the abutment block to move and compress the buffer spring. Due to the inclined surface design of the snap-fit ​​block and the abutment block, the snap-fit ​​block can be quickly removed from the insertion hole, realizing the quick installation and disassembly between the two ditches.

[0022] 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.

[0023] Reference Figure 1 - Figure 5This utility model provides an embodiment of a drainage ditch for soil and water conservation, comprising a ditch 1 as the main body. In use, to effectively conserve soil and water, multiple side drainage channels 101 are symmetrically formed on the inner wall of the ditch 1. These side drainage channels 101 can guide some of the water flow into the soil outside the ditch 1 when the main waterway has excessive flow, thus diverting and reducing pressure. Simultaneously, multiple energy dissipation sills 103 are spaced apart on the inner bottom wall of the ditch 1 along the water flow direction. When water flows through these energy dissipation sills 103, it generates drops and eddies, thereby drastically consuming the kinetic energy of the water flow, significantly reducing the flow velocity, and effectively preventing high-speed water flow from scouring the bottom of the ditch 1 and the downstream riverbed. Bottom infiltration holes 102 are also formed on the bottom wall of the ditch 1 between two adjacent energy dissipation sills 103. Water flow slowed by the energy dissipation sills 103 will stagnate briefly at these holes, allowing some water to infiltrate through them, replenishing groundwater and reducing the total surface runoff. In addition, to prevent larger debris such as fallen leaves and branches from entering the ditch 1 and causing blockages, a baffle plate 2 is installed on top of the ditch 1. The baffle plate 2 has an adjustment component 6 inside, which includes an inner grid plate 601 that can slide within the inner groove 201. By manually moving the lever 603 on top of the limiting plate 602, the limiting plate 602 and the inner grid plate 601 can slide together, thereby changing the size of the grid gaps in the baffle plate 2. This allows for flexible adjustment based on the amount of debris in different seasons or environments, achieving a balance between effectively blocking most debris and ensuring smooth water flow into the ditch 1. The baffle plate 2 slides with its bottom side slide plate 202 in conjunction with the side slide groove 203 at the top of the ditch 1, making installation and removal for cleaning very convenient.

[0024] Two insert blocks 3 are provided on one side of the trench 1 unit, while two corresponding insertion holes 4 are provided on the other side. During installation, simply align one insert block 3 of trench 1 and push it into the insertion hole 4 of the adjacent trench 1. To achieve a quick and secure connection, a locking component 7 is cleverly designed inside the insert block 3. When the insert block 3 is pushed into the insertion hole 4, the inclined surface at the bottom of the locking block 701 inside it first contacts the inclined surface of the abutment block 706 fixed inside the insertion hole 4. Under the action of the pushing force, the locking block 701 is subjected to force along the inclined surface, causing the slider 702 to slide into the insert block 3, while simultaneously compressing the pressure spring 703 at its rear. When the top of the locking block 701 completely passes the abutment block 706, it loses the restraining force of the abutment block 706, and the previously compressed pressure spring 703 instantly rebounds, pushing the slider 702 and the locking block 701 back to their original positions, so that the top of the locking block 701 is firmly locked into the inner wall of the insertion hole 4, thus completing the locking process. When disassembly is required, the operator simply pushes the insert 3 a short distance further into the insertion hole 4. The inclined surface of the locking block 701 will then contact the inclined surface of the abutment block 706 again, causing it to retract back into the insert 3. During this process, the abutment block 706 will move along the slide rod 704 and compress the buffer spring 705 behind it. At this point, keeping the locking block 701 in its retracted state, the insert 3 can be pulled outwards to easily complete the disassembly. The presence of the buffer spring 705 not only facilitates disassembly but also cushions the impact at the connection point. In addition to the side connection, a set of central insert blocks and insertion holes 5 are also provided at the corresponding positions on the bottom wall of the ditch 1 to further enhance the stability of the connection and the accuracy of alignment, ensuring the linearity and stability of the entire drainage ditch.

[0025] Working Principle: When this equipment is in operation, surface runoff carrying mud, sand, fallen leaves, and other debris approaches the top of the ditch 1 and is initially intercepted by the baffle plate 2 located at the top. By manually moving the lever 603 on the limit plate 602, the inner grid plate 601 slides within the inner groove 201 of the baffle plate 2, thereby changing the size of the grid gaps to adapt to different debris filtration needs. After the water flows through the baffle plate 2 into the ditch 1, it flows along its inner bottom wall and sequentially passes through multiple energy dissipation sills 103. At each energy dissipation sill 103, the water falls, altering its linear flow pattern. In the area between two adjacent energy dissipation sills 103, some of the slowed water seeps downwards through the bottom infiltration holes 102 on the bottom wall. When the water volume in the ditch 1 is too large, excess water is diverted outwards through the side drainage channels 101 on both sides of the ditch 1. During the splicing and installation of multiple trench units, the insert block 3 at one end is aligned with the insertion hole 4 at the other end and pushed in. The locking component 7 inside the insert block 3 begins to work. The inclined surface at the bottom of the locking block 701 inside contacts the inclined surface of the abutment block 706 inside the insertion hole 4. Under the force, the slider 702 moves inward and compresses the pressure spring 703 behind it, causing the locking block 701 to temporarily retract. When the locking block 701 completely passes the abutment block 706, the elastic force of the pressure spring 703 pushes the slider 702 and the locking block 701 back to their original positions, so that the locking block 701 is locked in place on the inner wall of the insertion hole 4. During disassembly, the insert block 3 is pushed inward again. The locking block 701 contacts the abutment block 706 again and retracts. At the same time, the abutment block 706 moves along the slide rod 704 and compresses the buffer spring 705 behind it. At this time, the insert block 3 can be pulled out of the insertion hole 4. The entire splicing structure is further reinforced by the insertion of the central insert block on the bottom wall of ditch 1 into the insertion hole 2 5.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
