Description

Technical Field

[0001] The invention relates to the technical field of rapid soil drainage, in particular to a blind pipe water guide and a device for achieving rapid drainage of a planting muddy soil layer. Background Art

[0002] In garden planting, rapid drainage of silty soil layers has a vital impact on the growth of plants.

[0003] In the prior art, drainage of the silty soil layer in the garden area is mainly achieved by natural drainage or basic pipe drainage, but this method has the following disadvantages: First, drainage efficiency is low. Natural drainage relies on the natural infiltration and evaporation of water, which is slow and cannot meet the demand for rapid drainage during planting. Although drainage through foundation pipes is faster than natural drainage, the poor permeability of the silty soil makes it difficult for water to quickly collect in the pipes, resulting in limited drainage efficiency.

[0004] Second, it is prone to clogging. The silty soil layer contains a large amount of silt and other particulate matter. During the drainage process, these particulate matter easily enters the drainage pipes, causing pipe blockage, affecting the normal operation of the drainage system, requiring frequent cleaning and maintenance, and increasing usage costs and workload.

[0005] Third, uneven drainage. Natural drainage and foundation pipe drainage cannot ensure that moisture in every area of ​​the soil layer can be effectively drained, which easily leads to local water accumulation and affects the overall growth of the plants.

[0006] Based on this, it is necessary to design a blind pipe water guide device that can efficiently, stably and evenly achieve rapid drainage of the planting silt soil layer, so as to solve the problems existing in the existing drainage method and ensure the good growth of plants in the silt soil layer.

[0032] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only used as examples and are not intended to limit the scope of protection of the present invention. Figure 1-Figure 4 As shown in .

[0033] Example 1: A blind pipe water guide for achieving rapid drainage of silty soil layers for planting, comprising a water guide bend 1, wherein the left end of the water guide bend 1 is set as a screening liquid inlet, the middle part of the water guide bend 1 is set as a mud deposition part, and the right end of the water guide bend 1 is set as a water guide part. The screening liquid inlet, the mud deposition part and the water guide part are integrally formed to form the water guide bend 1; the screening liquid inlet is used to introduce excess water in the surrounding soil layer and to screen large-particle mud blocks, the mud deposition part is used to deposit and gather mud materials that follow the water, and the water guide part is used to connect with an external drainage pipeline and to conduct water overflowing into it to the outside.

[0034] The water bend 1 combines the sieve inlet, the slurry deposition section, and the water guide section in an integrated manner. When the blind-tube water guide is installed inside the silty soil layer of the planting area, the accumulated water in the surrounding soil layer will flow into the water bend 1. The sieve inlet will first contact the accumulated water and perform preliminary treatment on it; the slurry deposition section will receive the water from the sieve inlet and further precipitate the impurities therein; and the water guide section will eventually lead the treated water out to the external drainage pipeline. The integrated structure ensures that the various parts are tightly connected, allowing the water to flow smoothly inside and reducing the risk of leakage.

[0035] The sieving liquid inlet uses the fluidity and pressure difference of the water to allow the accumulated water in the soil layer to flow in through the filter holes 2 spaced apart on the surface, while large mud particles cannot pass through and are blocked outside, thereby achieving preliminary filtration of large mud impurities in the water. The water that has undergone preliminary filtration flows into the horizontal drainage inlet pipe 101 of the sieving liquid inlet and accumulates inside. As the liquid level rises, the water flows to the right under the pressure generated by the liquid level difference and enters the mud deposition section. The mud deposition section uses the slowing down of the water flow rate and the action of gravity to cause solid impurities such as small mud particles and stone particles carried in the water to settle in the mud deposition chamber 104. When the water level in the mud deposition section continues to rise, the clearer supernatant at the top will overflow to the right and enter the drainage diversion chamber 106 of the drainage diversion pipe 105. After the water enters the drainage cavity 106 , the drainage pipe 105 of the water guide part is connected to the external drainage pipeline, and the water is discharged with the help of the suction force of the external water pump or the gravity of the water itself.

[0036] The filtration function of the screening inlet section effectively prevents large mud particles from entering the subsequent structure, avoiding pipe blockage, ensuring continuous and unobstructed water flow, and reducing maintenance costs and equipment damage risks caused by blockage. The mud settling section further purifies the water and separates solid impurities, reducing the mud content of the discharged water, alleviating the burden on the external drainage pipeline and extending its service life. The water guide section achieves seamless connection with the external collection system, ensuring the complete and efficient completion of the entire drainage process, and improving the practicality and stability of the drainage.

[0037] Specifically, the blind-tube water guide in the present invention is mainly installed and fixed in a planting silt soil layer below the ground where water accumulates seriously. During installation, the blind-tube water guide maintains an inclination angle of 0-10° in the horizontal direction and keeps one end of the sieve liquid inlet at a high position, so as to facilitate the slow flow of water to the right. After installation, it is connected to an external drainage pipeline with a water pump.

[0038] The blind pipe water guide is installed in the planting silt soil layer under the ground where water accumulates seriously, in order to collect and treat the accumulated water directly from the source. During installation, an inclination angle of 0-10° is set, and one end of the filter inlet is at a high position. It uses the effect of gravity to allow the water to flow naturally and slowly to the right without additional power, reducing the dependence on additional power equipment. After the installation is completed, an external drainage pipeline with a water pump is connected. When the water in the drainage diversion cavity 106 accumulates to a certain level, the water pump is turned on regularly and the suction generated by the water pump is used to speed up the discharge of the water and achieve rapid drainage.

[0039] Installation below ground level ensures the water deflector maintains its position above ground, preventing disruption to surface activities. Furthermore, the deflector maintains better contact with accumulated water, effectively collecting it. Furthermore, its concealed underground location reduces the risk of mechanical damage to the deflector, extending its service life. The specific inclination angle ensures the natural flow of water without consuming additional energy, reducing operating costs.

[0040] Since the blind pipe water guide is placed in a planting muddy soil layer with serious water accumulation, the accumulated water inside the soil layer will continuously pass through multiple water filtering holes 2 (the number of water filtering holes 2 is set according to needs, and the design standard is to be able to quickly introduce water into the water guide bend 1) to continuously drain the excess water into the interior of the sieve liquid inlet part. When passing through the various water filtering holes 2 on the surface of the sieve liquid inlet part, the large particles of mud and other soil impurities in the water can be initially filtered and blocked.

[0041] In the planting silt soil layer with serious water accumulation, there is a high water pressure in the soil layer. Under the combined action of this pressure and gravity, the accumulated water flows to the sieve inlet of the blind pipe water guide. The number of water filter holes 2 on the surface of the sieve inlet is set according to the actual drainage needs to ensure sufficient water flow area and realize the rapid introduction of excess water into the water guide bend 1. The aperture of the water filter hole 2 is designed to be smaller than the size of large particles of mud. When the accumulated water passes through the water filter hole 2, the large particles of mud are intercepted outside the water filter hole 2, and only water and a small amount of fine impurities can enter the horizontal drainage inlet pipe 101 of the sieve inlet.

[0042] The number of drainage holes (2) can be flexibly adjusted to accommodate different waterlogging severity and soil particle distribution in silty soil layers. This flexible design greatly enhances the versatility and adaptability of the blind leg water guide, making it widely applicable to various complex soil environments.

[0043] Water continuously enters the horizontal drainage inlet pipe 101 of the screening liquid inlet part and accumulates therein. As the water accumulates, the water continuously flows to the right and enters the mud deposition part. In the process of water flow, some solid impurities (for example, small mud blocks, stone particles, etc.) are carried into the mud deposition chamber 104 of the mud deposition part for accumulation. As the water level continues to rise, the supernatant on the top overflows to the right and flows into the drainage drainage chamber 106 of the drainage drainage pipe 105 to complete the water accumulation.

[0044] After the water continues to pass through the water filter holes 2 and enter the horizontal drainage inlet pipe 101, due to the limited space inside the water bend 1, the water gradually accumulates and the liquid level continues to rise. When the liquid level difference reaches a certain level, the water flows rightward under the action of pressure and enters the mud deposition section. During the flow, the water has a certain amount of kinetic energy and will carry some solid impurities such as small mud blocks and stone particles with it into the mud deposition chamber 104 of the mud deposition section. As more water and impurities enter, the impurities in the mud deposition chamber 104 gradually accumulate, and the water continues to rise. Because the density of solid impurities is generally greater than that of water, they settle to the bottom of the mud deposition chamber 104 under the action of gravity. At this time, the relatively clear supernatant in the upper part continues to overflow to the right due to the liquid level difference, flowing into the drainage diversion chamber 106 of the drainage diversion pipe 105, and gradually accumulates in the drainage diversion chamber 106.

[0045] By regularly turning on the external water pump for a specified period of time, the water accumulated in the drainage and liquid guiding cavity 106 can be discharged to the outside and collected for utilization. At a certain period (for example, every 3 days or so), the external pump body is used to extract part of the collected water and transport it to the liquid filling joint 5 of the self-cleaning mechanism and inject it into the internal accumulation of the plunger tube cavity through the liquid filling joint 5. The water can rely on its own weight to flush the mud deposition cavity 104 of the U-shaped tube 103 downwards and discharge a small amount of accumulated silt to the mud outlet pipe 3, and continue to be discharged under the action of the external mud discharge pipeline with a pump.

[0046] It should be noted that, as needed, another external pump body is used to extract a portion of the collected water liquid and inject it into the plunger lumen through the liquid filling joint 5 of the self-cleaning mechanism.

[0047] When there are a lot of mud impurities accumulated inside the mud deposition chamber 104, it may not be possible to clean it simply by relying on the deadweight of the water accumulated inside the plunger tube cavity. Therefore, the garden maintenance personnel can manually press the pressure hand wheel 8 of the self-cleaning mechanism several times every day or every other day to quickly press down the accumulated water and quickly discharge the accumulated silt under the action of water pressure.

[0048] The specific operation is as follows: the pressure handwheel 8 is connected to the plunger rod 7, and the passive piston 6 is connected below the plunger rod 7. When the garden maintenance personnel press the pressure handwheel 8, the plunger rod 7 moves downward, which in turn pushes the passive piston 6 downward within the plunger lumen. This process compresses the water in the plunger lumen, causing the water pressure to increase dramatically. The increased water pressure generates a stronger impact force, quickly dislodging the large amount of silt accumulated in the mud deposition chamber 104 and discharging it through the mud discharge pipe 3.

[0049] Manual cleaning effectively complements automatic cleaning, increasing cleaning flexibility. When automatic cleaning fails, manual operation can promptly resolve the issue, ensuring that the mud deposition chamber 104 remains in good working condition and maintaining the efficient operation of the drainage system. This design fully considers the various situations that may be encountered during actual use, improving the device's ability to cope with complex environments and enhancing its practicality and reliability.

[0050] When pressing the hand wheel, the anti-blocking component can be pulled back and forth several times as needed. In the process of pulling and releasing, the flexible anti-corrosion steel wire rope 17 and the return scraper spring 13 can be used to cooperate to drive the spherical frame 14 and the coarse-diameter spherical screen 15 to move back and forth. In the process of movement, the accumulated silt is collided and pulled, thereby loosening it, making it easier to quickly impact it with water pressure.

[0051] Specifically, when the garden maintenance personnel pull back the lifting ring 18 on the top of the anti-blocking component, the lifting ring 18 drives the spherical frame 14 and the coarse-diameter spherical screen 15 connected thereto to move upward in the mud deposition chamber 104 through the flexible anti-corrosion steel wire rope 17.

[0052] When you release your grip, the return scraper spring 13 contracts, pulling the flexible, corrosion-resistant steel wire rope 17 and moving the spherical frame 14 and coarse-diameter spherical screen 15 downward. During this reciprocating motion, the spherical frame 14 and coarse-diameter spherical screen 15 continuously collide with and pull on the silt accumulated in the sludge deposition chamber 104, loosening its structure. Simultaneously, as the return scraper spring 13 expands and contracts, it scrapes the inner wall of the drainage chamber 102, removing any adhering impurities. This way, when the water pressure acts, it can more effectively flush away the loosened silt and scraped impurities, preventing them from clogging the filter hole 2 and the pipe.

[0053] The return and anti-blocking components further enhance the cleaning effect of the sludge deposition chamber 104, especially for stubborn sludge accumulation, by mechanically loosening it, significantly improving cleaning efficiency. Cleaning the inner wall of the drainage inlet chamber 102 and the water filter holes 2 ensures the proper functioning of the filtration inlet, maintaining the drainage efficiency and stability of the entire water guide. This structural design cleverly utilizes simple mechanical principles to clean and prevent blockage in key areas within the water guide, reducing manual cleaning workload and extending the service life of the device.

[0054] In addition, during the process of the return scraper spring 13 reciprocatingly extending and shortening in the left and right directions, it can scrape and clean the inner wall of the liquid inlet chamber 102, thereby cleaning the inner side of each water filter hole 2 to prevent the water filter hole 2 from being blocked.

[0055] One end of the return scraper spring 13 is fixed to the center of the left end of the drainage inlet chamber 102. When the return anti-blocking component is moved by the garden maintenance personnel, the return scraper spring 13 expands and contracts. During the extension process, the spring gradually stretches, exerting an outward force on the inner wall of the drainage inlet chamber 102, scraping off impurities adhering to the inner wall. During the contraction process, the spring contracts, scraping the inner wall again to ensure that impurities are completely removed. Because the drainage hole 2 is connected to the drainage inlet chamber 102, impurities scraped off by the spring will not block the drainage hole 2. Instead, they are carried out by the flowing water, thus cleaning the inside of the drainage hole 2.

[0056] This automatic cleaning function effectively prevents clogging of the filter hole 2, ensuring that the sieve inlet always maintains good filtration performance. No additional cleaning equipment or operation is required, and cleaning can be achieved only by the natural expansion and contraction movement of the return scraper spring 13, reducing maintenance costs and improving equipment reliability.

[0057] On the basis of any of the above technical solutions, further optimization is that: the screening liquid inlet part includes a horizontally arranged drainage liquid inlet pipe, a drainage liquid inlet cavity 102 is arranged inside the horizontal drainage liquid inlet pipe 101, the left end of the horizontal drainage liquid inlet pipe 101 is blocked, and a number of water filter holes 2 are respectively arranged on both sides of the surface of the horizontal drainage liquid inlet pipe 101, and the water filter holes 2 are used to block the large particles of mud from the planting silt soil layer. The right end of the horizontal drainage liquid inlet pipe 101 is integrally formed with the left end of the mud deposition part.

[0058] The horizontal drainage inlet pipe 101 achieves functional integration through differentiated design at both ends: the left end is blocked, forming a blind end, forcing water to enter the drainage inlet chamber 102 only through the filter holes 2 on either side; the right end is directly connected to the mud sedimentation area, ensuring that the filtered water can flow unimpeded into the next stage. The filter holes 2 are spaced apart on both sides, expanding the water inlet area. The linear structure of the horizontal drainage inlet pipe 101 also extends the water's retention time within the chamber, allowing large mud particles to settle to the bottom of the pipe due to gravity, further aiding filtration.

[0059] On the basis of any of the above technical solutions, further optimization is that: the mud deposition part includes a vertically arranged U-shaped tube 103, the left end of the U-shaped tube 103 is integrally connected to the right end of the horizontal drainage liquid inlet pipe 101, the right end of the U-shaped tube 103 is integrally connected to the left end of the water guide part, a mud deposition chamber 104 is provided at the bottom of the inner cavity of the U-shaped tube 103, and a mud discharge pipe 3 is installed at the central inner wall of the mud deposition chamber 104, and the mud discharge pipe 3 is connected to an external mud discharge pipeline with a pump.

[0060] The vertical structure of the U-shaped tube 103 utilizes gravity to efficiently separate water from impurities. After the water from the horizontal drainage inlet pipe 101 enters the left end of the U-shaped tube 103, the small impurities such as mud and gravel carried by it settle to the bottom of the U-shaped tube 103 under the action of gravity, forming a sludge accumulation in the mud deposition chamber 104. The supernatant rises along the vertical section on the right side of the U-shaped tube 103 and overflows into the drainage pipe 105 of the water guide. The mud discharge pipe 3 is located in the center of the mud deposition chamber 104, allowing the sludge to converge under the action of gravity. The external mud discharge pipeline with a pump uses negative pressure to extract the high-concentration sludge, achieving the targeted discharge of impurities.

[0061] Based on any of the above technical solutions, further optimization is that: the water guide part includes a horizontally arranged drainage guide tube 105, the left end of the drainage guide tube 105 is integrally connected to the right end of the U-shaped tube 103, and a drainage guide cavity 106 is provided inside the drainage guide tube 105, and the right end of the drainage guide cavity 106 is connected to an external drainage pipeline.

[0062] Drainage conduit 105 receives the supernatant from the overflow of U-shaped tube 103 and, leveraging the linear flow characteristics of the horizontal tube, smoothly conveys the liquid to an external drainage pipeline. This external drainage pipeline generates negative pressure through a pump, accelerating liquid discharge. It can also switch to collection mode (e.g., for connection to an irrigation system) or discharge mode (e.g., for connection to a municipal water treatment network) as needed.

[0063] On the basis of any of the above technical solutions, a further optimization is that: a self-cleaning mechanism is provided above the U-shaped tube 103 .

[0064] On the basis of any of the above technical solutions, further optimization is that: the self-cleaning mechanism includes a vertically arranged three-way plunger tube 4, the top of the three-way plunger tube 4 is sealed, the two branches 401 at the bottom of the three-way plunger tube 4 are respectively fixedly connected to the outer walls of the two vertical sections of the U-shaped tube 103 and are internally connected, and a liquid adding joint 5 connected to the plunger tube cavity inside thereof is integrally formed on one side of the upper outer wall of the vertical section of the three-way plunger tube 4, and the liquid adding joint 5 introduces the water collected after filtration into the plunger tube cavity and is used to flush the mud material accumulated in the mud deposition cavity 104.

[0065] The three-way plunger tube 4 is connected to the vertical section of the U-shaped tube 103 through two bottom branches 401, forming a dual-path water inlet flushing structure. After the liquid filling connector 5 is connected to the recycled water, the water forms a static pressure column in the plunger tube cavity. When the pressure handwheel 8 is pressed, the passive piston 6 moves downward, converting the static pressure energy into dynamic pressure energy. High-pressure water is simultaneously injected into the U-shaped tube 103 through the two branches 401, pressurizing the mud deposition chamber 104 on both sides to flush, avoiding the blind spot caused by one-sided flushing.

[0066] On the basis of any of the above technical solutions, further optimization is that: a return pressure component is installed in the plunger tube cavity of the vertical section of the three-way plunger tube 4; the return pressure component includes a passive piston 6 that is movably and sealingly installed in the plunger tube cavity of the vertical section of the three-way plunger tube 4, and the top of the passive piston 6 is coaxially fixed with a plunger rod 7, and the top of the plunger rod 7 movably passes through the sealing cover 20 at the top of the three-way plunger tube 4 and extends above it, and the top of the plunger rod 7 extends above the ground and is coaxially fixed with a pressure handwheel 8.

[0067] The passive piston 6 and the inner wall of the plunger tube cavity are precisely sealed to ensure no leakage when pressed. When the handwheel is pressed, the passive piston 6 moves downward to compress the water, and the water pressure is evenly transmitted to the mud deposition cavity 104 of the U-shaped tube 103; when the handwheel is released, the return spring 10 pushes the piston back to its original position.

[0068] On the basis of any of the above technical solutions, further optimization is as follows: a limit plate 9 is fixed on the outer wall of the plunger rod 7 above the sealing cover 20, a return spring 10 is sleeved on the outer wall of the plunger rod 7 between the limit plate 9 and the sealing cover 20, a restraint sleeve 11 is sleeved on the periphery of the return spring 10, the bottom of the restraint sleeve 11 is coaxially fixed to the top of the sealing cover 20, the top of the restraint sleeve 11 extends to the top of the limit plate 9, a dustproof upper cover 12 is fixedly installed on the top of the restraint sleeve 11, and the center hole of the dustproof upper cover 12 is movably sleeved on the outer wall of the plunger rod 7.

[0069] The limit plate 9 limits the maximum piston travel, preventing damage to the seal due to excessive pressure. The return spring 10 provides the return force, and the restraining sleeve 11 guides the spring compression direction to prevent lateral bending and failure. The dustproof cover 12 prevents dirt and debris from entering the restraining sleeve 11, ensuring smooth movement of the plunger rod 7.

[0070] On the basis of any of the above technical solutions, further optimization is that: the outer wall of the limiting plate 9 and the inner cavity side wall of the restraint sleeve 11 are clearance-fitted.

[0071] The blind pipe water guide also includes a return anti-blocking component installed in the tube cavity of the water guide elbow 1, and the return anti-blocking component is used to prevent blocking and cleaning of the drainage liquid inlet cavity 102, each of the water filter holes 2 and the mud deposition cavity 104.

[0072] The return-to-anti-blocking component utilizes a dual anti-blocking mechanism, combining mechanical linkage with hydraulic flushing, to enhance cleaning effectiveness. A flexible, corrosion-resistant steel wire rope 17 connects the spherical frame 14, the coarse-diameter spherical screen 15, and the fine-diameter spherical screen 16. When the lifting ring 18 is manually operated, the wire rope drives each component in reciprocating motion within the tube lumen. The spherical frame 14 and the screen break up sludge clumps through collision and screening. The return-to-scraper spring 13, by extending and contracting, scrapes and directs fluid into the inner wall of the liquid chamber 102 and the inner side of the filter hole 2, removing adhering impurities. The disturbed water flow generated during this movement can further carry impurities to the slurry deposit or discharge them.

[0073] On the basis of any of the above technical solutions, further optimization is that: the return anti-blocking component includes a return scraper spring 13 installed at the left end of the drainage liquid inlet chamber 102, and the left end of the return scraper spring 13 is fixed at the left end center of the drainage liquid inlet chamber 102, and also includes a spherical frame 14 and a coarse-diameter spherical screen 15 arranged on the left and right sides of the mud deposition chamber 104, and the outer wall of the spherical frame 14 and the outer wall of the coarse-diameter spherical screen 15 are clearance-matched with the inner wall of the mud deposition chamber 104, and also includes a fine-diameter spherical screen 16 arranged on the left side of the drainage liquid guiding chamber 106, and the fine-diameter spherical screen The outer diameter of the sieve holes on the spherical surface of the screen 16 is smaller than the sieve hole diameter of the spherical surface of the coarse-diameter spherical screen 15. A flexible anti-corrosion steel wire rope 17 is provided in the tube cavity of the water guide bend 1 for connecting the spherical frame 14, the coarse-diameter spherical screen 15 and the fine-diameter spherical screen 16 in series. The left end of the flexible anti-corrosion steel wire rope 17 is fixed to the right end of the return scraper spring 13. The right end of the flexible anti-corrosion steel wire rope 17 bends upward and moves and seals the through hole at the top of the inner wall of the right end of the drainage and liquid guiding cavity 106 and extends upward to above the ground. A pulling ring 18 is fixedly installed on the top of the flexible anti-corrosion steel wire rope 17.

[0074] Pulled by the wire rope, the return scraper spring 13 stretches and contracts left and right. Its elastic deformation generates a scraping force that removes impurities adhering to the inner wall of the drainage chamber 102. As the spherical frame 14 and the coarse-diameter spherical screen 15 reciprocate within the sludge deposition chamber 104, they collide, squeeze, and sieve, breaking up lumpy sludge into particles less than 1 mm in size for easy flushing. The fine-diameter spherical screen 16 blocks fine impurities from entering the drainage chamber 106, creating a multi-stage filtration system. The flexible, corrosion-resistant wire rope 17 changes direction via the reversing pulley 19, ensuring synchronized operation of all components.

[0075] On the basis of any of the above technical solutions, further optimization is that: the sieve hole diameter of the spherical surface of the coarse-diameter spherical screen 15 is smaller than the aperture of the filter hole.

[0076] The coarse-diameter screen has a smaller aperture (e.g., 2mm) than the aperture of filter hole 2 (e.g., 5mm), creating a pore size gradient. Filter hole 2 intercepts large mud particles, while the coarse-diameter screen intercepts medium-sized particles (e.g., 2-5mm mud) that escape filter hole 2, preventing them from clogging the fine-diameter screen or the sedimentation chamber outlet. This design utilizes pore size differences to achieve impurity particle size classification, improving filtration accuracy.

[0077] Based on any of the above technical solutions, further optimization is that: a reversing wheel 19 is installed in the drainage and liquid guiding cavity 106 above the turning part of the right end of the flexible anti-corrosion steel wire rope 17, and both ends of the central axis of the reversing wheel 19 are movably inserted into the turning holes on the front and rear sides of the drainage and liquid guiding cavity 106, and the flexible anti-corrosion steel wire rope 17 bypasses the reversing wheel 19 to achieve reversing.

[0078] When the lifting ring 18 moves upward, the wire rope drives the reversing wheel 19 to rotate, converting the vertical pulling force into horizontal traction force, thereby preventing friction and wear between the wire rope and the through hole at the top of the drainage and diversion cavity 106. The surface of the reversing wheel 19 is polished to reduce the resistance of the wire rope movement.

[0079] Example 2: Compared with Example 1, this example is different in that it also includes the following technical features: The present invention also provides a blind-leg water guide device, comprising the blind-leg water guide as described above, wherein the right end of the drainage and liquid guiding cavity 106 of the blind-leg water guide is connected to an external drainage pipeline with a water pump, and when installed, the water guide bend 1 of the blind-leg water guide is entirely placed in the silt soil layer below the ground.

[0080] The blind-leg water diversion system, centered around a blind-leg water diverter, works in conjunction with an external pump and drainage piping. The blind-leg water diverter is buried in the muddy soil layer beneath the ground. The sieving inlet collects water from the soil through the water filter holes 2 and performs a preliminary filtration of large mud particles. The water then flows into the mud sedimentation section, where any solid impurities, such as fine mud and gravel particles, settle in the mud sedimentation chamber 104. The supernatant liquid overflows into the drainage chamber 106.

[0081] When water accumulates within drainage chamber 106 to a certain level, an external pump activates, generating suction using negative pressure to rapidly extract the water from chamber 106 and transport it to a designated location via a drainage pipeline, completing the drainage process. The entire device utilizes the natural pressure and gravity of accumulated water in the soil layer, along with the power of the pump, to efficiently collect, treat, and drain accumulated water in muddy soils.
