Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering and its ecological restoration technology, and in particular to an ecological slope protection and maintenance device for the Yellow River water conservancy project. Background Technology

[0002] As a vital national infrastructure project, the stability of the Yellow River dikes and slopes directly impacts flood control safety and the ecological environment. In the construction of the Yellow River water conservancy project, ecological slope protection is an important means to prevent soil erosion, reinforce dikes, and improve the surrounding ecological environment. To ensure the survival rate and growth quality of the slope vegetation, continuous and uniform water supply is required. Currently, maintenance methods mostly involve laying pipeline systems to collect rainwater or using river water for gravity drip irrigation.

[0003] However, the natural environment along the Yellow River is quite unique. Not only is there a lot of wind and sand, but the rainwater or the Yellow River water used for irrigation contains a large amount of silt, stones, and impurities such as dead branches and fallen leaves. The existing slope protection and maintenance devices lack effective pretreatment structures for water sources with high sediment content, which makes it easy for impurities to enter the pipeline system with the water flow and accumulate on the pipe walls or at the water outlet, causing blockage of the irrigation system and seriously affecting the normal water intake of vegetation.

[0004] Furthermore, existing drip irrigation components are installed at the end of the pipe using methods such as screw tightening or glue bonding. When silt blockage occurs and needs to be cleared, or when the water flow needs to be adjusted according to the different water requirements of the slope vegetation at different growth stages, it is difficult for operators to quickly disassemble or replace the drip irrigation components. This results in time-consuming and labor-intensive maintenance work, and it is impossible to achieve precise flow adjustment, making it difficult to meet the long-term, efficient, and low-cost maintenance needs of ecological slope protection in the Yellow River water conservancy project.

[0005] Therefore, this utility model proposes an ecological slope protection and maintenance device for Yellow River water conservancy projects to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing technology, the ecological slope protection maintenance device for the Yellow River water conservancy project directly uses water with high sand content, which is prone to pipe blockage and cannot flexibly adjust the drip irrigation flow according to the different water requirements of different vegetation, resulting in poor maintenance effect and maintenance difficulties. The present invention aims to provide an ecological slope protection maintenance device for the Yellow River water conservancy project with improved structure that can effectively solve the above problems.

[0007] This utility model provides an ecological slope protection and maintenance device for the Yellow River water conservancy project, comprising: a slope, a planting trough opened on the outer wall of the slope, a water storage tank set at the top of the slope, a main pipe connected to the bottom of the water storage tank, a branch pipe connected to the bottom of the main pipe and extending into the planting trough, a replacement mechanism set at the end of the branch pipe, and a filter mechanism set inside the installation groove on the top wall of the water storage tank.

[0008] The replacement mechanism includes a drip screen and a slide rod fixedly connected to the outer wall of the drip screen. A slide groove and a slot connected to the slide groove are provided on the inner wall of the end of the pipe.

[0009] Furthermore, the slide rod is slidably connected to the inside of the slide groove and locked inside the slot. The top wall of the water storage tank is provided with an installation groove. A filter mechanism is provided inside the installation groove. The filter mechanism includes filter screen one and filter screen two, which are slidably connected to each other in the installation groove from bottom to top. A limit block is locked and fixed at the top opening of the installation groove, and the bottom wall of the limit block abuts against the top wall of filter screen two.

[0010] Preferably, a knob is fixedly connected to the outer wall of the drip screen, the knob is located outside the branch pipe, and there are two sliding rods, which are symmetrically distributed on the upper and lower sides of the outer wall of the drip screen.

[0011] Preferably, an elastic sealing ring is fixedly connected to the inner wall of the end of the branch pipe. The elastic sealing ring is located deep in the groove and abuts against the outer wall of the drip net. The elastic sealing ring undergoes elastic deformation under pressure to fill the gap between the drip net and the branch pipe.

[0012] Preferably, sliders are fixedly connected to both the front and rear sides of the bottom wall of filter screen two, and the sliders are slidably connected inside the mounting groove. The outer wall of filter screen one is slidably connected to the bottom end of the inner wall of the mounting groove and is located below filter screen two.

[0013] Preferably, the top wall of the limiting block is provided with a second sliding groove, and the left and right sides of the inner wall of the second sliding groove are slidably connected with pin blocks. The outer walls of the two pin blocks are fixedly connected with springs on adjacent sides, and the springs are in a compressed or naturally extended state.

[0014] Preferably, circular grooves are provided on both the left and right sides of the inner wall of the mounting groove and near the top opening. The end of the pin block away from the spring extends under the action of the spring force and gets stuck in the circular groove, thereby preventing the limiting block from leaving the mounting groove.

[0015] Preferably, the main pipeline is connected to multiple branch pipelines, which are distributed at intervals along the slope surface, and each branch pipeline is equipped with a planting trough at its end.

[0016] Preferably, the top opening of the water storage tank is covered with a filter screen one and a filter screen two. Filter screen one is used to filter fine sand, and filter screen two is used to intercept stones and large particles of debris.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem that existing Yellow River water conservancy project maintenance devices, by setting a double-layer filtration structure consisting of filter screen one and filter screen two on the top of the water storage tank, and cooperating with a limiting quick-release structure consisting of springs and pin blocks, can easily cause pipe blockage and filter screen cleaning and maintenance when directly using water sources with high sand content. It achieves the effect of graded filtration of water source, effectively intercepting fine sand and large particles of debris, ensuring the long-term stable operation of drip irrigation system, and allowing the filter screen to be quickly disassembled and cleaned without the need for tools, which significantly reduces the difficulty of later operation and maintenance.

[0019] 2. This utility model solves the problems of traditional drip irrigation devices having a fixed flow rate that cannot meet the water requirements of different vegetation and the cumbersome disassembly and assembly of drippers by setting a drip net replacement mechanism consisting of a knob, slide bar, slide groove and slot at the end of the branch pipe and sealing it with an elastic sealing ring. It achieves the ability to quickly replace drip nets of different specifications according to the growth needs of vegetation to adjust the drip irrigation flow, realize precise maintenance, avoid water waste or soil compaction, and improve replacement efficiency and operation convenience by using a snap-fit ​​connection structure.

[0030] Please refer to Figures 1 to 6 This utility model provides an ecological slope protection and maintenance device for Yellow River water conservancy projects. It aims to solve the problem that existing Yellow River water conservancy project slope protection and maintenance devices, which directly use rainwater or Yellow River water with high sediment content, are prone to causing irrigation pipe blockage and cannot flexibly adjust the drip irrigation flow according to the water requirements of different vegetation.

[0031] Please refer to Figure 1 and Figure 2 The ecological slope protection and maintenance device for the Yellow River water conservancy project includes a slope body 1, a planting trough 5 opened on the outer wall of the slope body 1, a water storage tank 2 set on the top of the slope body 1, a main pipe 3 connected to the bottom of the water storage tank 2, and a branch pipe 4 connected to the bottom of the main pipe 3 and extending into the planting trough 5. The slope body 1 is used as the installation base for the entire ecological slope protection and maintenance device for the Yellow River water conservancy project. The water storage tank 2 is used to collect rainwater or store irrigation water. The main pipe 3 and the branch pipe 4 are used to transport the water source in the water storage tank 2 to the planting trough 5.

[0032] Please refer to Figure 3 and Figure 4The inner wall of the end of the branch pipe 4 is provided with a sliding groove 604 and a slot 605 communicating with the sliding groove 604. The replacement mechanism 6 includes a drip screen 601. A sliding rod 603 is fixedly connected to the outer wall of the drip screen 601. The sliding rod 603 is slidably connected inside the sliding groove 604 and inserted into the slot 605. A knob 602 located outside the branch pipe 4 is fixedly connected to the outer wall of the drip screen 601. An elastic sealing ring 606 is fixedly connected to the inner wall of the end of the branch pipe 4. The elastic sealing ring 606 abuts against the outer wall of the drip screen 601. By rotating the knob 602, the sliding rod 603 moves between the sliding groove 604 and the slot 605, realizing the quick disassembly and replacement of the drip screen 601. Please refer to [reference needed]. Figure 5 and Figure 6 The filter mechanism 7 includes a filter screen 1 702 and a filter screen 2 703 stacked sequentially inside the mounting groove 701 from bottom to top. A limiting block 705 is fixedly engaged at the top opening of the mounting groove 701. The bottom wall of the limiting block 705 abuts against the top wall of the filter screen 2 703. Sliding blocks 704 are fixedly connected to both the front and rear sides of the bottom wall of the filter screen 2 703. The sliding blocks 704 are slidably connected inside the mounting groove 701. A sliding groove 2 706 is provided on the top wall of the limiting block 705. A pin block 707 is slidably connected to both the left and right sides of the inner wall of the sliding groove 2 706. A spring 708 is fixedly connected to the adjacent side of the outer wall of the two pin blocks 707. A circular groove 709 is provided on both the left and right sides of the inner wall of the mounting groove 701. The end of the pin block 707 away from the spring 708 is engaged in the circular groove 709.

[0033] As a preferred embodiment, in order to ensure the stability of the drip net 601 installation and prevent the drip net 601 from falling off under the impact of water flow, there are two slide rods 603, and the two slide rods 603 are symmetrically distributed on the upper and lower sides of the outer wall of the drip net 601.

[0034] As another preferred embodiment, in order to ensure the sealing of the connection between the branch pipe 4 and the drip net 601 and to prevent water from leaking from the gap, the elastic sealing ring 606 is located deep in the groove 604 and abuts against the outer wall of the drip net 601. The elastic sealing ring 606 undergoes elastic deformation under pressure to fill the gap between the drip net 601 and the branch pipe 4.

[0035] As another preferred embodiment, in order to achieve comprehensive maintenance of the vegetation of the entire slope 1, the main pipe 3 is connected to multiple branch pipes 4, which are distributed at intervals along the slope surface of the slope 1, and each branch pipe 4 is provided with a planting trough 5 at its end.

[0037] Working principle: When the water storage tank 2 collects rainwater, the rainwater first passes through the filter screen 2 703 to intercept stones, dead branches and large particles of debris, and then passes through the filter screen 1 702 to filter fine sand. The clean water source flows into each branch pipe 4 through the main pipe 3, and finally passes through the drip net 601 to drip evenly into the planting trough 5 to nourish the vegetation.

[0038] When it is necessary to adjust the flow rate or replace the drip screen 601, the operator rotates the knob 602 to rotate the drip screen 601, causing the slide rod 603 to move out of the slot 605 and into the first slide groove 604. Then, the operator pulls the knob 602 outward to disengage the drip screen 601 from the branch pipe 4. After replacing the new drip screen 601, the operator pushes the slide rod 603 into the first slide groove 604 until the elastic sealing ring 606 is compressed. The operator then rotates the knob 602 again to make the slide rod 603 snap into the slot 605 to complete the locking and sealing.

[0039] When the filter mechanism 7 needs to be cleaned, press the two pin blocks 707 inward to compress the spring 708 and disengage it from the circular groove 709. Then remove the limiting block 705 and slide the filter screen 2 703 and filter screen 1 702 upward in sequence for cleaning.
