Description

Technical Field

[0001] This invention relates to the field of landfill engineering technology, and more specifically, to a leachate drainage pipe unblocking device. Background Technology

[0002] The landfill is equipped with leachate drainage pipes at the bottom. These pipes are perforated perforated pipes, through which leachate flows into the pipes and is eventually collected in the leachate equalization tank.

[0003] Over time, organic particles and sludge undergo physical, chemical, and biological processes in the high-salt, high-alkali leachate environment. The particles clump together or metal ions separate and form layered scale. The perforations on the leachate drainage pipes are easily blocked, leading to an increase in the amount of leachate in the landfill, a rise in the leachate level, or even overflow. This affects the safety of the landfill area and may even cause serious environmental pollution accidents.

[0004] Currently, leachate drainage pipes primarily rely on gravity flow due to slope for wastewater discharge, with limited research on horizontal dredging of landfill leachate drainage networks. Existing technologies for horizontal dredging of drainage pipes typically employ a winch-based traction rope, which is mainly suitable for straight pipe sections but not for curved sections, failing to achieve comprehensive dredging and cleaning of the entire landfill. Winches require electricity, posing a safety risk. Furthermore, current technologies often use steel wool attached to the traction rope for cleaning the drainage pipes. However, steel wool can only clear blockages in the upper and lower perforations of the pipe, failing to clean the perforations on the sides, thus preventing thorough cleaning. Summary of the Invention

[0048] The leachate drainage pipe unblocking device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, the leachate drainage pipe unblocking device according to an embodiment of the present invention includes a drainage pipe 10, a load-bearing block 20, an equalization tank 30, a pull rope 40, a cleaning component 50, and an equalizer 60.

[0050] Specifically, the outer circumferential surface of the guide pipe 10 is provided with multiple guide holes 11. A load-bearing block 20 is located at one end of the guide pipe 10. An adjusting pool 30 is located at the other end of the guide pipe 10. A pull rope 40 is located inside the guide pipe 10, with one end movably connected to the load-bearing block 20 and the other end passing through the adjusting pool 30. A cleaning assembly 50 is located on the pull rope 40 and inside the guide pipe 10; a portion of the cleaning assembly 50 is retractable, and the other portion corresponds at least partially to the position of the guide holes 11, so as to clean the guide pipe 10 during the movement of the pull rope 40. An adjuster 60 is located on the adjusting pool 30, with a portion of the adjuster 60 extending into the adjusting pool 30, and the other end of the pull rope 40 passing through the adjuster 60. The adjuster 60 is used to adjust the length and rotation angle of the pull rope 40.

[0051] In other words, the leachate drainage pipe unblocking device according to embodiments of the present invention is mainly used at the bottom of landfills. See also Figure 1The leachate drainage pipe unblocking device mainly consists of a drainage pipe 10, a load-bearing block 20, a regulating tank 30, a pull rope 40, a cleaning component 50, and a regulator 60. The drainage pipe 10 can be a straight pipe section, a curved pipe section, or a combination of straight and curved pipe sections. Multiple drainage holes 11 are provided on the outer circumference of the drainage pipe 10. At the bottom of the leachate drainage pipe 10 upstream of the landfill area, a load-bearing block 20 is installed, buried in the landfill material, to provide fixation. The regulating tank 30 is installed at the other end of the drainage pipe 10. The pull rope 40 is installed inside the drainage pipe 10, with one end movably connected to the load-bearing block 20 and the other end passing through the regulating tank 30. The pull rope 40 can be made of PVC-coated steel wire rope. The pull rope 40 and the load-bearing block enable the entire force-bearing system to work together.

[0052] like Figure 1 As shown, the cleaning assembly 50 is mounted on the pull rope 40 and is located inside the guide pipe 10. A portion of the cleaning assembly 50 is retractable, and another portion corresponds at least partially to the position of the guide hole 11. The cleaning assembly 50 can perform comprehensive cleaning and dredging of the guide pipe 10 during the movement of the pull rope 40. Figure 1 As shown, the regulator 60 is installed on the regulating pool 30, and a part of the regulator 60 extends into the regulating pool 30. The other end of the pull rope 40 passes through the regulator 60. The regulator 60 can be used to adjust the length and rotation angle of the pull rope 40. By adjusting the length and rotation angle of the pull rope 40 through the regulator 60, the cleaning assembly 50 is driven to perform a comprehensive cleaning of the guide hole 11 and the sludge removal inside the pipe.

[0053] This invention does not require other large equipment. One end of the pull rope 40 is connected to the load-bearing block 20, and the other end is connected to the adjuster 60. It is easy to install, the device structure is durable, and the operation is simple and safe.

[0054] Therefore, according to an embodiment of the leachate drainage pipe unblocking device of the present invention, a pull rope 40 is provided inside the drainage pipe 10, and a retractable cleaning component 50 is provided on the pull rope 40. Simultaneously, an adjuster 60 is used to adjust the length and rotation angle of the pull rope 40, thereby driving the cleaning component 50 to thoroughly clean the drainage hole 11 and remove sludge from the pipe. This unblocking device is fixed by a load-bearing block 20, and the load-bearing block 20 and the pull rope 40 together achieve the linkage effect of the entire force-bearing system. The leachate drainage pipe unblocking device of the present invention does not require electricity, is safe to use, and is suitable for cleaning straight and curved pipe sections.

[0055] In some specific embodiments of the present invention, a plurality of guide holes 11 are arranged in rows at intervals on the outer peripheral surface of the guide pipe 10, and two adjacent rows of guide holes 11 are respectively a first row of holes 111 and a second row of holes 112, and the first row of holes 111 and the second row of holes 112 are spaced apart to form a preset angle. The plurality of guide holes 11 are distributed in a quincunx pattern on the outer peripheral surface of the guide pipe 10.

[0056] In other words, such as Figure 2 As shown, multiple guide holes 11 can be arranged in rows at intervals on the outer circumferential surface of the guide pipe 10, with adjacent rows of guide holes 11 being the first row of holes 111 and the second row of holes 112, respectively. The guide pipe 10 can have quincunx-shaped through-holes, so that the multiple guide holes 11 are distributed in a quincunx pattern on the outer circumferential surface of the guide pipe 10 (see...). Figure 3 and Figure 4 The first row of holes 111 and the second row of holes 112 are spaced apart to form a preset angle, which can be 30°. The guide pipe 10 has strip holes (guide holes 11) every 200mm along the length of the pipe. The guide holes 11 are 15mm high and 30mm long.

[0057] According to one embodiment of the present invention, the contact surface between the guide pipe 10 and the load-bearing block 20 is sealed, and the load-bearing block 20 is provided with a rotating ball 21 on the side facing the guide pipe 10. The pull rope 40 is connected to the rotating ball 21 so as to drive the rotating ball 21 to rotate relative to the load-bearing block 20.

[0058] In other words, the contact surface between the drain pipe 10 and the load-bearing block 20 is sealed to prevent debris particles from entering and clogging the pipe. Figure 1 As shown, a rotating ball 21 is provided on the side of the load-bearing block 20 facing the guide pipe 10. The pull rope 40 is connected to the rotating ball 21, and the pull rope 40 can drive the rotating ball 21 to rotate relative to the load-bearing block 20.

[0059] In this invention, a load-bearing block 20 is installed at the port of the leachate drainage pipe 10 at the bottom of the upstream section of the landfill area, buried in the landfill material, to provide fixation. The load-bearing block 20 is a prefabricated concrete cube with a diameter of 200mm. The center of the concrete cube near the port of the leachate drainage pipe 10 has a hollowed-out hemisphere with a diameter of 10mm, providing a hollow space for movement. This space is enclosed and can accommodate a rotating ball 21 with a diameter of 5mm, which can move within it. The rotating ball 21 has a connecting end for a pull rope 40. When the other end of the PVC-coated steel wire rope (pull rope 40) rotates in a circle, the rotating ball 21 rotates accordingly, forming a complete force-bearing system.

[0060] According to one embodiment of the present invention, the regulating pool 30 is provided with a cover plate 31, and a portion of the regulator 60 extends out of the cover plate 31.

[0061] In other words, see Figure 1 The regulating tank 30 is equipped with a cover plate 31, and a portion of the regulator 60 extends out of the cover plate 31. The regulator 60 can adjust and control the length and rotation angle of the plastic-coated steel wire rope, thereby achieving comprehensive hole cleaning and sludge removal work inside the pipeline.

[0062] In some specific embodiments of the present invention, such as Figure 1 As shown, the cleaning assembly 50 includes multiple elastic elements 51 and multiple flexible rings 52. The elastic elements 51 are spaced apart on the pull rope 40 to divide the pull rope 40 into multiple segments. The flexible rings 52 are spaced apart on the pull rope 40, with at least one flexible ring 52 between adjacent elastic elements 51. Each flexible ring 52 has at least one needle tip 521, which can extend into the corresponding guide hole 11 during the movement of the pull rope 40 to clean the guide hole 11. Figure 5 and Figure 6 As shown, each soft ring 52 has four needle tips 521, which are distributed in an X-shape, and each needle tip 521 corresponds to a corresponding guide hole 11.

[0063] In the extension direction of the guide tube 10, the interval between two adjacent guide holes 11 is 150-250mm, the interval between two adjacent soft rings 52 is 300-500mm, and the interval between two adjacent soft rings 52 is twice the interval between two adjacent guide holes 11.

[0064] In other words, see Figure 1 The cleaning assembly 50 mainly consists of multiple elastic elements 51 and multiple soft rings 52. The multiple elastic elements 51 are spaced apart on the pull rope 40 to divide the pull rope 40 into multiple segments. The elastic elements 51 can be springs. Figure 5 and Figure 6 As shown, each flexible ring 52 is provided with at least one needle tip 521, constructing the flexible ring 52 with a needle-like structure. Multiple flexible rings 52 are spaced apart on the pull rope 40, and at least one flexible ring 52 is provided between two adjacent elastic elements 51. Several springs are connected in the middle of the PVC-coated steel wire rope (pull rope 40), providing a range of movement for the needle-like flexible rings 52 on the PVC-coated steel wire rope when the springs are stretched and retracted. The maximum stretch length when the springs are stressed is 200mm, which is exactly the distance from the needle-like flexible ring 52 to the next guide hole 11. When the springs retract and reset, the flexible ring 52 returns to its original position.

[0065] See Figure 1 After the plastic-coated steel wire rope of the load-bearing block 20 and before the first flexible ring 52, a spring (elastic element 51) must be installed to ensure that the first needle-shaped flexible ring 52 can move forward when the plastic-coated steel wire rope is stretched.

[0066] like Figure 6 As shown, the needle tip 521 can extend into the corresponding guide hole 11 during the movement of the pull rope 40 to clean the guide hole 11. Each flexible ring 52 can be provided with four needle tips 521, which are distributed in an X-shape, and each needle tip 521 corresponds to a specific guide hole 11. In the extending direction of the guide tube 10, the interval between two adjacent guide holes 11 is 150-250 mm, and the interval between two adjacent flexible rings 52 is 300-500 mm. Furthermore, the interval between two adjacent flexible rings 52 is twice the interval between two adjacent guide holes 11.

[0067] In this invention, the plastic-coated steel wire rope (pull rope 40) can be treated for corrosion protection, and the steel wire rope is plastic-coated and embedded in the guide pipe 10. See also Figure 1 and Figure 6 Several needle-shaped flexible rings 52 are fixed to the plastic-coated steel wire rope. The needle-shaped flexible rings 52 are X-shaped and made of HDPE material. The ends of the X are four needle tips 521, which correspond to the perforations (drainage holes 11) of the leachate drainage pipe 10. The needle tips of the flexible rings 52 are made of corrosion-resistant medium-soft rubber. When the needle-shaped flexible rings 52 move or rotate, they will not scratch the inner wall of the leachate drainage pipe 10.

[0068] A needle-shaped flexible ring 52 is placed at 400mm intervals, and a perforated hole in the leachate drainage pipe 10 is placed at 200mm intervals. There is a gap between two adjacent needle-shaped flexible rings 52, with no perforated hole. That is, needle-shaped flexible rings 52 are placed in the odd-numbered rows of perforated holes, such as the first row, third row, fifth row, and n-1th row. When the wire rope is stretched, the needle-shaped flexible rings 52 in the odd-numbered rows of perforated holes will be positioned on the even-numbered rows, thus achieving the function of cleaning the pipe.

[0069] Before and after the bend in the leachate drainage pipe 10, needle-shaped soft rings 52 are installed on the plastic-coated steel wire rope to ensure uniform force distribution at the bend and that the steel wire rope and the rings remain in the center of the pipe without shifting.

[0070] According to one embodiment of the present invention, such as Figure 7As shown, the adjuster 60 includes a column 61, a hollow through-hole component 62, a rotary positioning component 63, an angle rotary button 64, and a limiting washer 65. The column 61 has an L-shaped structure. The hollow through-hole component 62 is L-shaped and located at a corner inside the column 61. The rotary positioning component 63 is located inside the column 61 and is adjacent to the hollow through-hole component. The angle rotary button 64 is located on the column 61. The limiting washer 65 is located on the angle rotary button 64. A pull rope 40 passes sequentially through the hollow through-hole component 62, the rotary positioning component 63, the angle rotary button 64, and the limiting washer 65 inside the column 61. Lubricant is injected into the hollow through-hole. The column 61 has a scale 611 in the direction away from the angle rotary button 64.

[0071] In other words, see Figure 7 The other end of the pull rope 40 (after the outlet of the leachate drain pipe 10) is connected to the short side of the horizontal section of the L-shaped regulator 60. The long side of the vertical section of the L-shaped regulator 60 is installed on the cover plate 31 of the regulating tank 30. The regulator 60 is an L-shaped cylinder and includes a column body 61, a spiral positioning device, an angle rotation button 64, and a limit washer 65. A hollow through-hole 62 is provided inside the center corner of the column body 61 of the regulator 60. The hole is filled with lubricant to reduce friction and provide movement for the wire rope (pull rope 40) when it turns at a right angle. At the same time, it provides better force and rotation for the wire rope at the corner, ensuring that the plastic-coated wire rope is always centered at both ends of the corner and will not be damaged during long-term use.

[0072] The center of the long vertical section of the column body 61 of the regulator 60 is a spiral positioning device (rotary positioning component 63) to ensure that the plastic-coated steel wire rope is always centered and subjected to uniform force, and it is connected to the hollow hole device for threading. Figure 7 As shown, the top of the long vertical section of the column body 61 of the adjuster 60 has an angle rotary button 64. A scale 611 is set around the contact surface below the angle rotary button 64, indicating clockwise (0°, 60°, 120°, 180°) and counterclockwise (0°, 60°, 120°, 180°). Above the angle rotary button 64 is a limiting washer 65 for the plastic-coated steel wire rope. When closed, it limits and fixes the plastic-coated steel wire rope. When open, it can control the stretching or contraction of a certain length. The portion of the adjuster 60 protruding from the top surface of the cover plate 31 has markings 611 indicating 0cm, 20cm, 40cm, 60cm, 80cm, etc., through which the movement of the plastic-coated steel wire rope on the column body 61 can be clearly observed.

[0073] After opening the limit pad by adjusting device 60 and stretching the PVC-coated steel wire rope by 20cm, the spring reaches its maximum stretch length of 200mm. This moves the flexible ring 52 to the next row of perforated holes, allowing further stretching to the 40cm, 60cm, and 80cm marks on scale 611. During this process, the flexible ring 52 carries the sediment from the pipe towards the regulating tank 30, achieving a good sludge removal effect. When the spring needs to return to its original state, the PVC-coated steel wire rope is retracted to the position on scale 6110, and the flexible ring 52 resets. The stretching and retraction reset process can break down the scale formed by the chemical action of metal ions on the inner wall of the pipe.

[0074] When the angle rotary button 64 is turned 60° clockwise, the plastic-coated steel wire rope rotates under the spiral positioning device, transmitting force to the hollow hole part 62. The rotating ball 21 on the load-bearing block 20 moves freely, causing the soft ring 52 inside the leachate drain pipe 10 to rotate 60° clockwise along the circumference. This brings the first needle tip (first needle tip 521) of the soft ring 52 to the position of the second needle tip (second needle tip 521), and the third needle tip (third needle tip 521) to the position of the fourth needle tip (fourth needle tip 521). When the angle rotary button 64 is turned 180° clockwise, the first needle tip reaches the position of the third needle tip, and the third needle tip reaches the position of the first needle tip, thus cleaning the perforated holes in the leachate drain pipe 10. The principle is the same when rotating counterclockwise; combining clockwise and counterclockwise rotations effectively cleans all perforated holes.

[0075] In this invention, one end of the PVC-coated steel wire rope is connected to the load-bearing block 20 on the upstream section of the leachate drainage pipe 10, and the other end is connected to the regulator 60 at the outlet of the leachate drainage pipe 10. The regulator 60 is fixedly installed on the cover plate 31. Several soft rings 52 are fixed on the PVC-coated steel wire rope, and several springs are added in the middle of the PVC-coated steel wire rope. By adjusting the length and rotation angle of the PVC-coated steel wire rope through the regulator 60, the springs are stretched or contracted to reset, causing the needle-shaped soft rings 52 on the PVC-coated steel wire rope to move back and forth in a circular motion. This process clears the sediment and cleans the perforations in the leachate drainage pipe 10.

[0076] In summary, the leachate drainage pipe unblocking device of the present invention is suitable for pipe sections with bends. Soft rings 52 with needle-like structures are installed before and after the bends. The plastic-coated steel wire rope is better positioned centrally within the pipe, preventing deviation. The plastic-coated steel wire rope is treated with plastic coating, so even if it comes into contact with the inner wall of the pipe, it will not damage or cut the pipe. It can unblock the leachate drainage pipes 10 network at the bottom of the entire landfill area, providing comprehensive cleaning and good sludge removal. This unblocking device does not require other large equipment. One end is connected to the load-bearing block 20, and the other end is connected to the adjuster 60, making installation convenient, the device structure durable, and the operation simple. The spring (elastic element 51) is placed between the two drainage holes 11 along the pipe length. When one end of the spring moves 200mm, the cleaning device moves to the next hole position. Relying on the tension and retraction of the spring, the structure is simple and easy to implement, requiring no power supply, ensuring safety and reliability, and solving the problem of electrical safety.
