Description

Technical Field

[0001] This utility model relates to the field of water replenishment device technology, and more specifically to an underground seepage water replenishment device. Background Technology

[0002] In arid and semi-arid regions, surface groundwater is scarce due to low rainfall and high evaporation, leading to degradation of forests and grasslands, and severe desertification. Replenishing the groundwater is crucial for ensuring plant growth in agricultural irrigation and landscaping. Currently, common groundwater replenishment methods include the following:

[0003] One method involves burying traditional plastic pipes underground, allowing water to permeate through perforations. However, plastic pipes present several problems. First, plastic materials are not environmentally friendly, are difficult to degrade, and can cause long-term soil pollution. Second, the perforation method for plastic pipes makes it difficult to effectively control the extent of water infiltration.

[0004] Another method is to use natural ditches or depressions for water storage and replenishment, but this method is greatly limited by terrain and climate conditions; in arid areas or flat areas, it is difficult to form effective ditches or depressions, which cannot meet the water replenishment needs.

[0005] In addition, there are some underground water replenishment devices with complex mechanical structures. Although these devices can achieve relatively precise water replenishment control, they are complex in structure, expensive, and difficult to install and maintain, making them unsuitable for large-scale promotion and application.

[0006] Therefore, how to provide an environmentally friendly, simple-structured device that can effectively achieve underground water conveyance and replenishment to meet the actual needs of agricultural irrigation, landscaping and other fields is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the present invention provides an underground seepage and water replenishment device, which aims to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An underground water conveyance and replenishment device includes a branch channel pipe connected to a water supply pipe, and a channel water distribution pipe connected to the branch channel pipe. The channel water distribution pipe and the branch channel pipe form an angle. Both the channel water distribution pipe and the branch channel pipe are made of plant branches and have tubular structures with permeable slits on their sidewalls.

[0010] Through the above technical solution, this utility model provides an underground infiltration and replenishment water device that uses plant branches as the material for the pipe body, which can gradually degrade in the natural environment. Compared with traditional non-degradable materials such as plastic pipes, it reduces the negative impact on soil structure and ecological environment caused by the difficulty in decomposing materials. The material properties of the plant branches themselves make the water flow relatively slowly through the infiltration gaps, allowing the water to infiltrate into the surrounding soil at a more uniform speed and range. The channel water distribution pipe and the support rod through the pipe form an angle, and the specific angle between the two can be determined according to needs to meet different infiltration ranges and directions. This utility model has a simple structure, and the slow infiltration method is conducive to the full diffusion and adsorption of water in the soil, improving water utilization. At the same time, it can also reduce the rapid loss of water, allowing water to be retained in the soil for a longer time to meet the needs of continuous plant growth.

[0011] Preferably, in the above-mentioned underground infiltration and water replenishment device, the channel water distribution pipe has a seepage rope inside, and there is a gap between the seepage rope and the inner wall of the channel water distribution pipe. The seepage rope has good water absorption and conductivity, which can guide water from the pipe to the surrounding soil, improving water replenishment efficiency and diffusion capacity; the gap design with the pipe wall avoids the risk of blockage caused by the rope sticking to the wall, and maintains seepage stability.

[0012] Preferably, in the above-mentioned underground infiltration and water replenishment device, both the outer sides of the branch channel pipe and the channel distribution pipe are wrapped with straw mats. The straw mats wrap the outside of the pipes, forming a filter layer that prevents soil particles from entering the gaps, avoiding blockages and ensuring smooth infiltration. Simultaneously, the straw mats themselves have a certain water absorption and retention capacity, which can further promote water infiltration and diffusion, improving the water replenishment effect; they can also serve as reinforcement for the pipe structure, preventing deformation due to underground pressure.

[0013] Preferably, in the above-mentioned underground infiltration and water replenishment device, the branch channel pipes are horizontally arranged underground, and an impermeable layer is laid at the bottom of the branch channel pipes; the branch channel pipes are pipe structures spliced ​​together by multiple first connecting pipes, and adjacent first connecting pipes are connected by straight pipes; each first connecting pipe has a tee pipe fitted on its outer wall, one end of the channel water distribution pipe is connected to the outlet end of the tee pipe, and the other end of the channel water distribution pipe is a free end. The impermeable layer prevents water from seeping too deep, locking it in the plant root layer and improving water utilization; the spliced ​​structure facilitates installation and transportation, and the length can be adjusted according to actual needs; the tee pipe realizes water diversion, so that water can be evenly distributed to each channel water distribution pipe, achieving effective control of the infiltration range.

[0014] Preferably, the above-mentioned underground seepage water replenishment device further includes a water-blocking dam, within which a three-way valve is installed. The inlet end of the three-way valve is connected to the water supply pipe, and the two outlet ends of the three-way valve are respectively connected to the first connecting pipe. The three-way valve can adjust the water volume entering each of the first connecting pipes according to the water replenishment needs of different areas, improving the flexibility and accuracy of water replenishment and avoiding waste of water resources.

[0015] Preferably, in the above-mentioned underground infiltration and water replenishment device, the ends of the first connecting pipes located on both sides are equipped with first plugs. This prevents water from leaking from the pipe ends, ensures that water can be transported and infiltrated along a predetermined path, improves the sealing and stability of the device, and ensures the water replenishment effect; at the same time, it can prevent backflow of sediment.

[0016] Preferably, in the above-mentioned underground seepage and water replenishment device, a maintenance pipe is sleeved on the outside of the first connecting pipe, and an inspection port is opened at the top of the maintenance pipe, with a cap at the inspection port. The maintenance pipe is nested outside the main pipe, allowing for localized inspection / cleaning by opening the cap, avoiding full pipe excavation and improving maintenance efficiency.

[0017] Preferably, in the above-mentioned underground infiltration and water replenishment device, the branch channel pipe is vertically arranged underground. The branch channel pipe is a pipe structure spliced ​​together from multiple sections of second connecting pipes with progressively increasing diameters from top to bottom. Adjacent second connecting pipes are connected by diversion pipes. The diversion pipe includes a vertical main channel pipe and a diversion extension pipe. The top end of the vertical main channel pipe is fixed to the bottom end of the second connecting pipe of the upper layer. The bottom end of the vertical main channel pipe is a closed structure and is fixed to the inner side of the second connecting pipe of the lower layer by a bracket. An annular overflow gap is formed between the outer wall of the bottom end of the vertical main channel pipe and the inner wall of the second connecting pipe. One end of the diversion extension pipe is connected to the interior of the vertical main channel pipe, and the other end is connected to the channel water distribution pipe. This structure can penetrate to different underground depths. By setting channel water distribution pipes in each layer, water can be transported to soils at different depths to meet the stratified water needs of different plant root systems. The vertical main channel pipe guides water from the upper layer to the lower layer, and the diversion extension pipe further diverts water to the channel water distribution pipe. This structural design allows water to be evenly distributed across all layers, preventing localized areas from receiving excessive or insufficient water flow and ensuring that the soil within the entire coverage area receives relatively uniform water replenishment.

[0018] Preferably, in the above-mentioned underground infiltration and water replenishment device, the water supply volume of the water supply pipe is greater than the drainage flow rate of the diversion extension pipe, so that the water overflows through the vertical main pipe and flows into the second connecting pipe of the next layer through the annular overflow gap. The water supply volume being greater than the drainage flow rate of the diversion extension pipe ensures that the water overflows through the vertical main pipe and flows into the second connecting pipe of the next layer through the annular overflow gap, guaranteeing that water can be evenly distributed to each layer, improving the uniformity of water replenishment in the vertical direction, and avoiding localized water shortages or water accumulation.

[0019] Preferably, in the above-mentioned underground seepage and water replenishment device, a cap is fixed to the top of the uppermost second connecting pipe, and the cap has a flow port in the middle that communicates with the water supply pipe. The cap on the top of the uppermost second connecting pipe, connected to the water supply pipe, seals the pipe end while simultaneously establishing a water supply connection, ensuring the normal operation of the device, preventing water leakage from the top, and improving the device's sealing and stability.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an underground seepage and water replenishment device, which has the following beneficial effects:

[0021] 1. This utility model uses plant branches to make the pipe body. These materials can degrade in the natural environment and will not remain in the soil for a long time like traditional plastic and metal pipes. This reduces the long-term negative impact on soil structure and ecological environment. At the same time, it realizes the resource reuse of agricultural or forestry waste, reduces resource waste, and increases soil fertility and improves the soil after decomposition.

[0022] 2. The permeable gaps on the side walls of the branch channel pipe and the channel water distribution pipe of this utility model allow water to permeate into the surrounding soil evenly and slowly. Compared with traditional perforated pipes, the permeation is more uniform, avoiding excessive or insufficient local water replenishment. Moreover, the slow permeation facilitates the full diffusion and adsorption of water in the soil, improving water utilization, reducing rapid loss, and meeting the needs of continuous plant growth.

[0023] 3. The horizontal layout scheme of this utility model is suitable for large areas of farmland, lawns and other areas. Through the design of impermeable layer, splicing structure and three-way valve, it can achieve large-area uniform water replenishment and flexible control of water volume. The vertical layout scheme can adapt to water replenishment needs at different depths. Both layout schemes can adapt to different types of soil and ensure good water replenishment effect.

[0024] 4. The vertically arranged branch channel pipe of this utility model is spliced ​​together with multiple sections of second connecting pipes with progressively increasing diameters. Combined with the diversion pipe structure, it can penetrate to different depths underground, delivering water to soil at different depths to meet the water needs of different plant root systems. It can also adapt to the characteristics of soil at different depths under complex geological conditions, achieving effective water replenishment. The water supply capacity of the water supply pipe is set to be greater than the drainage flow of the diversion extension pipe, enabling the device to adapt to high-flow water supply situations. When supplying high-flow water, the water flow can be quickly and smoothly distributed to each layer through the vertical main pipe and the annular overflow gap, avoiding problems such as pipe blockage or excessive pressure, ensuring normal operation, and improving water replenishment efficiency.

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.

[0041] See appendix Figure 1 To be continued Figure 11 This utility model discloses an underground infiltration and replenishment water device, including a branch channel pipe 2 connected to a water supply pipe 1, a channel water distribution pipe 3 connected to the branch channel pipe 2 and communicating with its interior, the channel water distribution pipe 3 and the branch channel pipe 2 forming an angle, the channel water distribution pipe 3 and the branch channel pipe 2 are both made of plant branches and the side walls of both have a tubular structure with permeable gaps.

[0042] To further optimize the above technical solution, plant branches can be tubular structures made by smoking, carbonizing, bending and straightening plant paper strips, etc. The cross-section of the tubular structure can be circular, elliptical, triangular, square or other shapes with permeable gaps.

[0043] To further optimize the above technical solution, the channel water distribution pipe 3 has a seepage rope 31 inside, and there is a gap between the seepage rope 31 and the inner side wall of the channel water distribution pipe 3.

[0044] To further optimize the above technical solution, the outer sides of both the branch channel pipe 2 and the channel water distribution pipe 3 are wrapped with branch grass curtains 4.

[0045] To further optimize the above technical solution, the outer sides of the branch channel pipe 2 and the channel water distribution pipe 3 can be wrapped with 1-2 layers of branch and grass curtain 4, or the specific number of layers can be determined according to the actual situation.

[0046] To further optimize the above technical solution, when manufacturing the branch channel tube 2, annular fixing plates 9 for supporting branches can be installed inside the branch channel tube 2 at intervals of 30-200cm. The edge of the annular fixing plate 9 has multiple evenly distributed perforations 91 along its circumferential direction. The branches pass through the perforations 91 to achieve support for the branches. If the length of a single branch channel tube 2 is less than 30cm, the annular fixing plates 9 can be used at both ends of the branch channel tube 2.

[0047] To further optimize the above technical solution, the thickness of the annular fixing piece 9 and the spacing between two adjacent perforations 91 can be determined according to the actual situation.

[0048] Example 1:

[0049] See appendix Figure 1-6 This embodiment discloses an underground infiltration and water replenishment device. The branch channel pipe 2 is horizontally arranged underground, and the bottom of the branch channel pipe 2 is covered with an impermeable layer 5. The branch channel pipe 2 is a pipe structure spliced ​​by multiple first connecting pipes 21. Adjacent first connecting pipes 21 are connected by a straight pipe 22. Each first connecting pipe 21 has a three-way pipe 23 sleeved on its outer wall. One end of the channel water distribution pipe 3 is connected to the outlet end of the three-way pipe 23, and the other end of the channel water distribution pipe 3 is a free end.

[0050] To further optimize the above technical solution, before laying the impermeable layer 5, a horizontal seepage storage channel needs to be dug (the specific dimensions can be determined according to the actual situation). The bottom of the channel should be leveled. Then, depending on the degree of soil seepage, the impermeable layer 5 is constructed: first, a 2 to 5 cm thick layer of plant debris and grass is laid, with the grass spread flat on top of the plant debris. A 2 to 8 cm thick layer of fine soil is then laid on top of the grass, followed by another 2 to 5 cm thick layer of grass and plant debris. Finally, organic nutrient soil is laid on top of the grass and plant debris. Depending on the soil seepage, 1 to 5 layers of organic nutrient soil are laid. At this point, the impermeable layer 5 is constructed / laid. The branch-and-trunk pipe 1 is laid on the upper surface of the impermeable layer 5, and then 1-2 layers of branch and grass curtain 4 are wrapped around the outer wall of the branch-and-trunk pipe 1 to prevent mud and sand from entering. The channel water distribution pipe 3 extends into the surrounding soil.

[0051] To further optimize the above technical solution, the tee pipe 23 can be a right-angle tee pipe or an inclined tee pipe. When it is a right-angle tee pipe, the channel water distribution pipe 3 is perpendicular to the first connecting pipe 21, allowing it to extend vertically into the surrounding soil to achieve water replenishment. When it is an inclined tee pipe, the angle between the channel water distribution pipe 3 and the first connecting pipe 21 is an acute angle, and it is arranged inclined downwards, which can also meet the needs of different depths. Of course, according to the actual situation, right-angle tee pipes and inclined tee pipes can also be set at different positions in a set of devices. The specific angle is determined according to actual needs to meet different infiltration ranges and directions.

[0052] To further optimize the above technical solution, a water-blocking dam 6 is also included. A three-way valve 61 is installed inside the water-blocking dam 6. The inlet end of the three-way valve 61 is connected to the water supply pipe 1, and the two outlet ends of the three-way valve 61 are respectively connected to the first connecting pipe 21.

[0053] To further optimize the above technical solution, the ends of the first connecting pipes 21 located on both sides are provided with first plugs 211.

[0054] To further optimize the above technical solution, an inspection tube 24 is sleeved on the outside of the first connecting tube 21. An inspection port is opened at the top of the inspection tube 24, and a cap 241 is provided at the inspection port. It should be noted that an inspection tube 24 can be sleeved on the outside of each first connecting tube 21, or an inspection tube 24 can be set at intervals of several first connecting tubes 21. The adjustment can be made according to the actual situation.

[0055] To further optimize the above technical solution, the outer side of the first connecting pipe 21 is wrapped with 1-2 layers of straw curtain 4.

[0056] To further optimize the above technical solution, at the opening of the tee pipe 23 away from the channel water distribution pipe 3, such as... Figure 6 As shown, a water-separating device 8 is provided. The water-separating device 8 includes a screw 81, two nuts 82, two washers 83, and a water-separating plate 84. The middle part of the screw 81 is a smooth rod structure, and its upper and lower sides have opposite thread designs. The two nuts 82 are threaded to the upper and lower parts of the screw 81, respectively. The two washers 83 are fixed to the two nuts 82 and abut against the side wall of the tee pipe 23. The water-separating plate 84 is installed on the outside of the lower nut 82. Figure 6 As shown.

[0057] To further optimize the above technical solution, the size of the gasket 83 and the water-proof plate 84 are determined according to the diameter of the first connecting pipe 21 and the water-proofing requirements, and the structure is designed to facilitate replacement.

[0058] To further optimize the above technical solution, the three-way valve 61, the three-way pipe 23, the inspection pipe 24 and the first connecting pipe 21 are all fastened with fasteners to prevent disconnection from the first connecting pipe 21. The fasteners can be clamps or other structural components.

[0059] Example 2:

[0060] Participate in the attached Figure 3 , 7 -11, This embodiment discloses an underground infiltration and replenishment water device. The branch channel pipe 2 is vertically arranged underground. The branch channel pipe 2 is a pipe structure spliced ​​together by multiple sections of second connecting pipes 25 with the diameter increasing from top to bottom. Adjacent second connecting pipes 25 are connected by a diversion pipe 26. The diversion pipe 26 includes a vertical main pipe 261 and a diversion extension pipe 262. The top end of the vertical main pipe 261 is fixed to the bottom end of the second connecting pipe 25 of the upper layer. The bottom end of the vertical main pipe 261 is a closed structure and is fixed to the inner side of the second connecting pipe 25 of the lower layer by a bracket 263. An annular overflow gap is formed between the outer wall of the bottom end of the vertical main pipe 261 and the inner wall of the second connecting pipe 25. One end of the diversion extension pipe 262 is connected to the inside of the vertical main pipe 261, and the other end is connected to a channel water distribution pipe 3.

[0061] Before use, a vertical water storage and infiltration channel needs to be dug. The specific size can be determined according to the actual situation. Multiple connected second connecting pipes 25 are vertically placed into the water storage and infiltration channel, and the channel water distribution pipe 3 extends into the surrounding soil.

[0062] To further optimize the above technical solution, the outer side of the second connecting pipe 25 is wrapped with 1-2 layers of straw curtain 4.

[0063] To further optimize the above technical solution, the diversion extension pipe 262 can be arranged perpendicular to the vertical main pipe 261, or it can be arranged inclined downward relative to the vertical main pipe 261. The specific included angle is determined according to actual needs to meet different permeation ranges and directions.

[0064] To further optimize the above technical solution, the water supply volume of the water supply pipe 1 is greater than the drainage flow of the diversion extension pipe 262, so that the water flow overflows through the vertical main pipe 261 and flows into the second connecting pipe 25 of the next layer through the annular overflow gap.

[0065] To further optimize the above technical solution, a pipe cap 7 is fixed at the top of the uppermost second connecting pipe 25, and the middle of the pipe cap 7 has a flow port that communicates with the water supply pipe 1.

[0066] To further optimize the above technical solution, multiple evenly distributed through holes are provided on the top and bottom walls of the cap 7 along its circumference. The multiple through holes surround the flow port. The through holes allow the branches to be inserted and also form a water flow channel. The water from the water supply pipe 1 enters through the flow port and then enters the interior of the second connecting pipe 25.

[0067] To further optimize the above technical solution, when the branch channel pipe 2 is arranged vertically, one branch channel pipe 2 can be set up or multiple branch channel pipes 2 can be set up around the plant according to the type and size of the plant. At the same time, according to the planting distance, such as the long interval between the planting of trees and shrubs, two adjacent branch channel pipes 2 can be connected by adjacent water pipes to achieve water flow.

[0068] Example 3:

[0069] Based on Example 1 or Example 2, a water replenishment effect monitoring component is added. The monitoring component includes a wireless humidity sensor, a pressure sensor, and a stem flow meter.

[0070] A wireless humidity sensor is buried 10-20cm away from the channel water distribution pipe on the side (the location can be determined according to the actual situation). The burial depth is consistent with the depth of the plant's main root system. The sensor is connected to the ground gateway through a LoRa module. At the same time, a pressure sensor is installed at the water inlet of the three-way valve to monitor the water supply pressure in real time. A stem flow meter is installed at the stem of the plant to detect the water absorption status.

[0071] The gateway needs to be pre-configured with irrigation control:

[0072] When the soil moisture content is <18%, the solenoid valve on water supply pipe 1 will be automatically opened to replenish water; when the pressure sensor reading is >0.25MPa and lasts for 5 minutes, a pipe blockage alarm will be sent to the terminal; when the stem flow meter detection value is <10cm / h and the soil moisture content is >20%, it is determined to be a root disease, and a water reduction warning will be activated. The user will take corresponding measures based on the feedback information.

[0073] Meanwhile, it should be noted that for areas with poor soil permeability (such as clay and compacted soil), ventilation pipes are added; the ventilation pipes are also made of plant branches and trunks, with ventilation holes on their side walls, and the pipes are covered with a branch and grass curtain 4 to prevent clogging; the ventilation pipes are buried together with the branch and trunk channel pipes 2 and the channel water distribution pipes 3 to form a "water replenishment-ventilation" dual-channel system.

[0074] All the above-mentioned structural components are fastened together by fasteners to prevent them from being disconnected from the first connecting pipe 21, the second connecting pipe 25, the channel water distribution pipe 3, etc. The fasteners can be clamps or other components.
