[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] This invention provides a phosphorus removal device for river water, such as... Figure 1-17As shown, the river water phosphorus removal device includes: a water flow channel box 1, an inlet guide box 2, and a baffle plate 3. The water flow channel box 1 is placed in the river channel according to the water flow direction. Both sides of the water flow channel box 1 have openings for water inlet and outlet. The inlet guide box 2 is fixedly installed on the inlet side of the water flow channel box 1 to guide water into the water flow channel box 1. Both sides of the inlet guide box 2 have openings for water inlet and outlet. The baffle plate 3 is fixedly installed on the inlet side of the inlet guide box 2 to close the river channel. The baffle plate 3 has an inlet 4 corresponding to the inlet guide box 2, and a filter screen 5 is fixedly installed at the inlet 4 to filter impurities. Adjustable plates 6 are hinged to both sides of the baffle plate 3 to adjust the angle according to the river channel width, cooperating with the baffle plate 3 to close the river channel. A regenerated resin box 7 is fixedly installed on the top of the water flow channel box 1. Multiple phosphorus removal mesh boxes 8 are placed longitudinally inside the water flow channel box 1. The screen boxes 8 are evenly arranged along the water flow direction and are filled with phosphorus removal resin 12 for adsorbing and removing phosphorus from the water. The top of the water flow channel box 1 has an opening that communicates with the regeneration resin box 7 and allows the phosphorus removal screen boxes 8 to slide. At least one of the phosphorus removal screen boxes 8 is located outside the water flow channel box 1 and inside the regeneration resin box 7 for resin regeneration. The bottom of each of the multiple phosphorus removal screen boxes 8 is detachably equipped with a water-sealing base 9 using a track groove 13 and a track bar 14. The top of each of the multiple phosphorus removal screen boxes 8 is detachably equipped with a water-sealing top plate 10 using a track groove 13 and a track bar 14. The water-sealing base 9 at the bottom of the phosphorus removal screen box 8 inside the water flow channel box 1 is tightly fitted to the bottom inner wall of the water flow channel box 1. The water-sealing top plate 10 at the top closes the opening at the top of the water flow channel box 1. The water-sealing base 9 at the bottom of the phosphorus removal screen box 8 inside the regeneration resin box 7 closes the opening at the top of the water flow channel box 1. The water-sealing top plate 10 at the top is located inside the regeneration resin box 7.

[0037] In this embodiment, during use, based on the survey results, a water-blocking plate 3 is installed on one side of the river channel, and an inlet 4 is opened on the water-blocking plate 3, with a filter screen 5 installed. Then, according to the width of the river channel, the angle of the adjusting plate 6 is adjusted so that it, together with the water-blocking plate 3, closes off a portion of the river channel, ensuring that the water flow can smoothly enter the inlet guide box 2. Subsequently, the river water passes through the filter screen 5 to remove impurities and enters the water flow channel box 1 through the openings on both sides of the inlet guide box 2. Inside the water flow channel box 1, the river water flows sequentially through multiple evenly arranged phosphorus removal screen boxes 8. These phosphorus removal screen boxes 8 are filled with phosphorus removal resin 12, which can effectively adsorb and remove phosphorus from the water. When the phosphorus removal resin 12 in a certain phosphorus removal screen box 8 reaches saturation, it can be slid out of the water flow channel box 1 and moved to the regeneration resin box 7 for resin regeneration treatment. At the same time, a new or regenerated phosphorus removal screen box 8 can be replaced to maintain the continuity of phosphorus removal work. During the sliding and replacement of the phosphorus removal screen box 8, the water sealing base 9 and the water sealing top plate 10 can ensure that the water flow will not leak and maintain the airtightness of the device.

[0038] The river water phosphorus removal device, through the design of the inlet guide box 2 and the baffle plate 3, effectively guides river water into the water flow channel box 1, and utilizes the phosphorus removal resin 12 in the phosphorus removal mesh box 8 to efficiently adsorb and remove phosphorus from the water. This design not only improves phosphorus removal efficiency but also avoids the interference and damage to river flow caused by traditional phosphorus removal methods. Furthermore, by adjusting the angle of the regulating plate 6, it can adapt to river channels of different widths, enhancing the applicability and flexibility of the device.

[0039] Furthermore, this phosphorus removal device employs a detachable water-sealing base 9 and a water-sealing top plate 10, as well as a sliding phosphorus removal screen box 8. This design not only facilitates the replacement of the phosphorus removal screen box 8 and resin regeneration operations but also ensures the device's sealing during replacement, preventing water leakage and waste. Simultaneously, the coordinated use of the track groove 13 and track strip 14 enables rapid installation and disassembly of the phosphorus removal screen box 8, improving work efficiency and operational convenience. This innovative design not only reduces maintenance costs but also extends the device's service life, providing a highly efficient and environmentally friendly solution for phosphorus removal from river water.

[0040] In a further preferred embodiment of the present invention, a material pad 11 is fixedly installed on the bottom inner wall of the phosphorus removal mesh box 8. The bottom of the material pad 11 is in contact with the top of the water sealing base 9. The phosphorus removal resin 12 is laid on the material pad 11 to support the phosphorus removal resin 12 when the phosphorus removal mesh box 8 is picked up or put down.

[0041] In this embodiment, a material pad 11 is fixedly installed on the bottom inner wall of the phosphorus removal screen box 8. The material pad 11 plays a crucial role when installing or removing the phosphorus removal screen box 8: its bottom is in close contact with the top of the water-sealing base 9, forming a stable support surface. The phosphorus removal resin 12 is evenly spread on top of the material pad 11. This ensures effective support for the phosphorus removal resin 12 when moving the phosphorus removal screen box 8, preventing resin spillage or leakage due to shaking or tilting. After removing the phosphorus removal screen box 8, it can be poured out through the top opening. This design greatly simplifies the replacement process of the phosphorus removal screen box 8 and improves the convenience and safety of operation.

[0042] In a further preferred embodiment of the present invention, the recycled resin box 7 is provided with a plurality of pick-up and drop-out ports 15 on one side of the sliding direction of the track bar 14 for picking up and dropping the phosphorus removal mesh box 8 located in the recycled resin box 7. The recycled resin box 7 is provided with a sealing plate at the pick-up and drop-out port 15 by bolts for sealing the pick-up and drop-out port 15.

[0043] In this embodiment, the regenerated resin tank 7 has multiple access ports 15 on one side of the track bar 14 in the sliding direction. These access ports 15 allow operators to easily access the descaling screen box 8 located inside the regenerated resin tank 7. To maintain the airtightness of the regenerated resin tank 7 and prevent resin leakage during the regeneration process, the access ports 15 are sealed with bolt-on detachable sealing plates. When it is necessary to access the descaling screen box 8, the operator can open the sealing plate and slide the descaling screen box 8 into or out of the regenerated resin tank 7 through the access port 15; after the operation is completed, the sealing plate is reinstalled to ensure the airtightness of the regenerated resin tank 7.

[0044] In a further preferred embodiment of the present invention, a water pump 16 is provided on one side of the regenerated resin tank 7. An inlet pipe 17 and a drain pipe 18 are fixedly installed at the inlet and outlet ends of the water pump 16, respectively. The drain pipe 18 is connected to the regenerated resin tank 7 and is used to pump in the resin regeneration solution. A waste discharge pipe 19 with a valve is also provided on one side of the regenerated resin tank 7 for discharging the regeneration solution after the regenerated resin is discharged.

[0045] In this embodiment, a water pump 16 is added to one side of the regenerated resin tank 7. An inlet pipe 17 and a outlet pipe 18 are fixedly installed at the inlet and outlet ends of the water pump 16, respectively. When it is necessary to regenerate the dephosphorizing resin 12, the operator can inject the resin regeneration solution into the water pump 16 through the inlet pipe 17, and then start the water pump 16 to pump the resin regeneration solution into the regenerated resin tank 7 through the outlet pipe 18. The dephosphorizing resin 12 in the dephosphorizing screen box 8 inside the regenerated resin tank 7 will then be regenerated under the action of the resin regeneration solution. After regeneration is complete, the operator can discharge the regenerated waste liquid by opening the valve on the waste discharge pipe 19. This design makes the resin regeneration process more automated and efficient.

[0046] In a further preferred embodiment of the present invention, the thickness of the water-sealing base 9 is 1.5 to 2 times the thickness of the water-sealing top plate 10, and the number of phosphorus removal mesh boxes 8 is at least two, with at least one phosphorus removal mesh box 8 located inside the water flow channel box 1.

[0047] In this embodiment, the thickness of the sealing base 9 is designed to be 1.5 to 2 times the thickness of the sealing top plate 10. This design aims to enhance the structural strength of the sealing base 9, ensuring that it can withstand greater water pressure and impact, thereby improving the stability and durability of the entire phosphorus removal device. Furthermore, at least two phosphorus removal screen boxes 8 are provided, and at least one phosphorus removal screen box 8 is located inside the water flow channel box 1. This layout allows the phosphorus removal process to proceed more continuously and efficiently, while also improving phosphorus removal efficiency and processing capacity. During this process, depending on the position of the phosphorus removal screen box 8, the sealing base 9 and the sealing top plate 10 alternately close the opening at the top of the water flow channel box 1.

[0048] The arrangement of at least two phosphorus removal screen boxes 8 allows for a more continuous phosphorus removal process. When the resin in one screen box 8 reaches saturation, it can be quickly replaced with another already regenerated screen box 8, ensuring the continuity and efficiency of phosphorus removal. Furthermore, the layout of at least one screen box 8 within the water flow channel box 1 also contributes to improved phosphorus removal efficiency, as the water flow can directly wash over the screen box 8, allowing the resin to fully contact and adsorb phosphorus elements in the water.

[0049] In a further preferred embodiment of the present invention, threaded rods 20 are hinged to the outer sides of both adjustment plates 6. Threaded sleeves 21 are threadedly fitted onto the threaded rods 20 for inserting into the stabilizing adjustment plates 6 on the riverbank. Stabilizing plates 22 are fixedly fitted onto the threaded sleeves 21 for contacting the stabilizing threaded sleeves 21 on the riverbank.

[0050] In this embodiment, threaded rods 20 are hinged to the outer sides of both adjusting plates 6 to facilitate adjustment of the support angle. A threaded sleeve 21 is threadedly fitted onto the threaded rod 20. When the threaded sleeve 21 rotates along the threaded rod 20 and moves downwards, it can be tightly inserted into the riverbed wall, thereby fixing the position of the adjusting plate 6. To enhance the contact stability between the threaded sleeve 21 and the riverbed wall, a stabilizing plate 22 is also fixedly fitted onto the threaded sleeve 21. The stabilizing plate 22 has a large contact area, which can better disperse pressure and increase friction, ensuring the stability of the threaded sleeve 21 and the entire adjusting plate 6 structure.

[0051] The combination of the threaded rod 20 and the threaded sleeve 21 allows the adjusting plate 6 to be adjusted according to the specific shape and conditions of the river channel, thus enabling the device to adapt to various complex water flow environments and river channel morphologies. This adaptability not only makes the installation of the device more convenient but also reduces the risk of damage caused by incompatibility with the environment, thereby extending the service life of the device. Simultaneously, the addition of the stabilizing plate 22 further enhances the connection strength between the device and the river channel wall, enabling the device to better resist water flow scouring and erosion during long-term use.

[0052] In a further preferred embodiment of the present invention, a closed telescopic plate 23 is fixedly installed on the inner side of each of the two adjusting plates 6, and the two closed telescopic plates 23 are fixedly connected to the water baffle 3 to seal the hinge joint between the water baffle 3 and the adjusting plate 6.

[0053] In this embodiment, to enhance the sealing at the hinge between the baffle plate 3 and the adjusting plate 6, sealing telescopic plates 23 are fixedly installed on the inner sides of both adjusting plates 6. These sealing telescopic plates 23 are made of elastic material, possessing a certain degree of elasticity and flexibility, and can tightly fit at the hinge between the baffle plate 3 and the adjusting plate 6, forming an effective sealing structure. When the adjusting plate 6 adjusts its angle according to actual needs, the sealing telescopic plates 23 can expand and contract accordingly, maintaining a tight fit with the hinge, thereby ensuring that the connection between the baffle plate 3 and the adjusting plate 6 will not leak due to water flow erosion or minor displacement during operation.

[0054] In a further preferred embodiment of the present invention, multiple inlet impeller shafts 24 are rotatably installed inside the inlet guide box 2. Both ends of the multiple inlet impeller shafts 24 extend outside the inlet guide box 2, and a synchronous sprocket 25 is fixedly installed at a common end. A synchronous chain 26 is sleeved on the synchronous sprocket 25 so that the multiple inlet impeller shafts 24 rotate together. An inlet motor 27 is fixedly installed on the outside of the inlet guide box 2, and the output shaft of the inlet motor 27 is fixedly connected to the end of the corresponding inlet impeller shaft 24.

[0055] In this embodiment, to improve the water intake efficiency and power transmission stability of the inlet guide box 2, multiple inlet impeller shafts 24 are innovatively rotatably installed inside the inlet guide box 2. Both ends of these inlet impeller shafts 24 extend to the outside of the inlet guide box 2, and a synchronous sprocket 25 is fixedly installed at one end of each shaft. The synchronous sprockets 25 are connected by a synchronous chain 26, ensuring that all inlet impeller shafts 24 can rotate synchronously. To achieve this rotation, an inlet motor 27 is fixedly installed on the outside of the inlet guide box 2, and its output shaft is firmly connected to the end of one of the inlet impeller shafts 24. When the inlet motor 27 starts, it drives the connected inlet impeller shaft 24 to rotate. Through the transmission of the synchronous sprocket 25 and the synchronous chain 26, all inlet impeller shafts 24 rotate synchronously. When the water flow rate and volume are sufficient, the inlet motor 27 does not need to be started.

[0056] In a further preferred embodiment of the present invention, the water inlet motor 27, the synchronous sprocket 25 and the synchronous chain 26 are provided with a protective cover 28, and the protective cover 28 is fixedly connected to the outside of the water inlet guide box 2.

[0057] In this embodiment, a protective cover 28 is installed to enhance the safety and durability of the water inlet motor 27, the synchronous sprocket 25, and the synchronous chain 26.

[0058] In a further preferred embodiment of the present invention, the height of the baffle plate 3 is greater than the height of the water flow channel box 1 and the water inlet guide box 2, and the height of the adjusting plate 6 is equal to the height of the baffle plate 3.

[0059] In this embodiment, the height of the baffle plate 3 is set to be greater than the height of the water flow channel box 1 and the inlet guide box 2. This design aims to ensure that the baffle plate 3 can effectively block the water flow and prevent it from bypassing the water flow channel box 1 and the inlet guide box 2 and directly affecting the phosphorus removal effect. At the same time, the height of the adjusting plate 6 is set to be equal to that of the baffle plate 3. This design not only maintains the aesthetics of the overall structure, but also ensures that the adjusting plate 6 can form a good fit with the baffle plate 3 when adjusting the angle, and together maintain the stable introduction of water flow.

[0060] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:

[0061] In another embodiment of the present invention, positioning slots 29 are provided on the other side of the water flow channel box 1, the regenerated resin box 7, the multiple water-sealing bases 9, and the multiple water-sealing top plates 10 relative to the loading / unloading port 15. A height positioning mechanism is provided on the outer side of the water flow channel box 1 and the regenerated resin box 7. The height positioning mechanism includes a connecting frame 30 located on the outer side of the water flow channel box 1 and the regenerated resin box 7. Multiple positioning plates 31 are fixedly installed on the connecting frame 30. The multiple positioning plates 31 are respectively inserted into the multiple positioning slots 29 to position the water-sealing bases 9 and the water-sealing top plates 10 within the water flow channel box 1 or the regenerated resin box 7. A connecting plate 32 is fixedly installed on the connecting frame 30. An electric telescopic rod 33 is fixedly installed on the regenerated resin box 7. The output rod of the electric telescopic rod 33 is fixedly connected to the connecting plate 32 to control the displacement of the connecting frame 30 and the positioning plates 31. The positioning plates 31 always seal the positioning slots 29 on the water flow channel box 1 and the regenerated resin box 7 to prevent leakage.

[0062] In this embodiment, the height positioning mechanism includes a connecting frame 30, positioning inserts 31, a connecting plate 32, and an electric telescopic rod 33. Specifically, positioning slots 29 are provided on the opposite side of the water flow channel box 1, the recycled resin box 7, and the multiple water-sealing bases 9 and water-sealing top plates 10 relative to the loading / unloading port 15. The connecting frame 30 is fixedly installed on the outside of the water flow channel box 1 and the recycled resin box 7, and multiple positioning inserts 31 are fixed on it. These positioning inserts 31 can be accurately inserted into the corresponding positioning slots 29, thereby positioning the water-sealing bases 9 and water-sealing top plates 10 within the water flow channel box 1 or the recycled resin box 7. In addition, a connecting plate 32 is fixed on the connecting frame 30, and an electric telescopic rod 33 is fixed on the recycled resin box 7. The output rod of the electric telescopic rod 33 is fixedly connected to the connecting plate 32. By controlling the extension and retraction of the electric telescopic rod 33, the displacement of the connecting frame 30 and the positioning plate 31 can be easily controlled, thereby realizing the quick fixing of the water sealing base 9 and the water sealing top plate 10, thus sealing the top opening of the water flow channel box 1 and ensuring that it is always closed; at the same time, it also facilitates the accurate positioning of the water sealing base 9 and the water sealing top plate 10 when removing or sliding in the phosphorus removal screen box 8, avoiding misalignment caused by random movement.

[0063] In another embodiment of the present invention, a reciprocating suspension transmission mechanism is provided inside the recycled resin tank 7 to control the phosphorus removal screen box 8, the water sealing base 9, and the water sealing top plate 10 within the water flow channel box 1 or the recycled resin tank 7. The reciprocating suspension transmission mechanism includes multiple winding shafts 34, all of which are rotatably installed inside the recycled resin tank 7. The number of winding shafts 34 is equal to the number of phosphorus removal screen boxes 8. The winding shafts 34 are located directly above the phosphorus removal screen boxes 8. Each of the multiple winding shafts 34 is fixedly fitted with a winding drum 35, and a lifting line 36 is wound around the winding drum 35. The bottom end of 36 is fixedly connected to the corresponding water-sealing top plate 10 below, for suspending the phosphorus removal screen box 8, the water-sealing base 9, and the water-sealing top plate 10. Multiple reciprocating shafts 37 are rotatably installed inside the regenerated resin box 7. The number of reciprocating shafts 37 is equal to the number of winding shafts 34. The reciprocating shafts 37 are located directly above the winding shafts 34. Gear disks 38 are fixedly fitted on each of the multiple reciprocating shafts 37, and pinions 39 are fixedly fitted on each of the multiple winding shafts 34. The multiple pinions 39 mesh with the corresponding gear disks 38, so that the multiple reciprocating shafts 37 drive the multiple winding shafts 34 respectively. The reciprocating shafts 37 are rotated, and reciprocating gears 40 are fixedly fitted on each of them. Four belt rollers 41 are rotatably installed inside the recycled resin tank 7. Each of the four belt rollers 41 is fixedly fitted with a limiting cylinder 42. The four limiting cylinders 42 are divided into two groups, each fitted with a first transmission belt 43 and a second transmission belt 44. The first transmission belt 43 and the second transmission belt 44 are located above and below the reciprocating gears 40, respectively. The first transmission belt 43 and the second transmission belt 44 rotate in opposite directions. A toothed assembly 45 is fixedly installed on the outer side of the first transmission belt 43, and a toothed assembly 46 is fixedly installed on the outer side of the second transmission belt 44. The toothed sets 45 and 46 alternately mesh with the reciprocating gears 40 to drive the reciprocating shaft 37 to rotate back and forth. A synchronous gear 47 is fixedly sleeved on one of the belt rollers 41 corresponding to the first and second transmission belts 43. The two synchronous gears 47 mesh with each other so that the rotation of any one belt roller 41 can drive the other set of belt rollers 41 to rotate in the opposite direction. A drive motor 48 is fixedly installed in the recycled resin box 7. A pulley 49 is fixedly sleeved on the output shaft of the drive motor 48 and on any one of the belt rollers 41. The same synchronous belt 50 is sleeved on the two pulleys 49.

[0064] In this embodiment, a reciprocating suspension transmission mechanism is installed inside the regenerated resin tank 7 to precisely control the position and movement of the descaling screen box 8, the water sealing base 9, and the water sealing top plate 10 within the water flow channel box 1 or the regenerated resin tank 7. The core components of the reciprocating suspension transmission mechanism include multiple winding spools 34, all securely rotatably mounted within the regenerated resin tank 7, with their number matching the number of descaling screen boxes 8. A reciprocating shaft 37 is positioned directly above each winding spool 34, and the two are linked by the precise meshing of a pinion 39 and a gear disc 38. A winding drum 35 is mounted on the winding spool 34, on which lifting lines 36 are wound. The bottom ends of these lifting lines 36 are tightly connected to the water sealing top plate 10, thus forming a suspension system. Furthermore, a drive system consisting of a first transmission belt 43, a second transmission belt 44, a reciprocating gear 40, a belt roller 41, and a synchronous gear 47 is also designed. Transmission belt 43 and transmission belt 44 are located above and below the reciprocating gear 40, respectively, and rotate in opposite directions. Their outer sides are respectively equipped with tooth sets 45 and 46, which can alternately mesh with the reciprocating gear 40, thereby driving the reciprocating shaft 37 to rotate reciprocally. The entire drive system is powered by a drive motor 48, which is connected to one of the belt rollers 41 via a synchronous belt 50, thus driving the entire system to operate.

[0065] Through the precise meshing of pinion 39 and gear disk 38, and the alternating meshing of tooth set 1 45 and tooth set 2 46 with reciprocating gear 40, precise control of the rotation angle and speed of winding shaft 34 is achieved, thereby ensuring the precise positioning and smooth movement of descaling screen box 8, water sealing base 9, and water sealing top plate 10. Furthermore, the counter-rotating design of transmission belt 1 43 and transmission belt 2 44, and the meshing action of synchronous gear 47, further enhance the stability and reliability of the transmission system, making the entire mechanism more stable and efficient during operation.

[0066] The entire transmission mechanism can be easily operated with a single drive motor, eliminating the need for cumbersome manual operation. This design not only simplifies the operation process and reduces labor costs, but also allows the device to adapt more flexibly to various working environments and needs. The advantages of the reciprocating suspension transmission mechanism are particularly evident in scenarios requiring frequent adjustments to the position of the phosphorus removal screen box or maintenance. It effectively shortens operation time, improves work efficiency, and provides users with a more convenient and efficient user experience.

[0067] In another embodiment of the present invention, a watertight plate 51 is fixedly installed inside the recycled resin box 7. The watertight plate 51 is located below the winding shaft 34, and the hoisting line 36 slides through the watertight plate 51. The height of the watertight plate 51 is higher than the drain end of the drain pipe 18.

[0068] In this embodiment, a watertight plate 51 is fixedly installed below the winding spool 34 to ensure the sealing of the hoisting line 36 during the passage process and prevent liquid leakage. Moreover, its setting height is higher than the drain end of the drain pipe 18, which prevents liquid from entering and maintains the stable operation of the entire system.

[0069] In another embodiment of the present invention, a trigger plate 52 is provided below the watertight plate 51. The trigger plate 52 is slidably installed inside the regenerated resin tank 7. The hoisting line 36 slides through the trigger plate 52. A trigger switch 53 is fixedly installed at the bottom of the watertight plate 51. The trigger end of the trigger switch 53 is arranged corresponding to the sliding direction of the trigger plate 52. The trigger switch 53 is connected to the water pump 16. Multiple positioning slots 54 are provided at the bottom of the trigger plate 52. Positioning blocks 55 are fixedly installed on the top of multiple water-sealing top plates 10. The positioning blocks 55 are correspondingly arranged with the positioning slots 54 so that after the water-sealing top plate 10 is raised into the regenerated resin tank 7, the positioning blocks 55 are engaged in the positioning slots 54. The suspension of the hoisting line 36 stabilizes the position of the water-sealed top plate 10, facilitating the removal of the phosphorus removal screen box 8 through the access port 15. It also causes the trigger plate 52 to slide up and trigger the trigger switch 53, causing the water pump 16 to pump in the regenerated liquid. A fixing block 56 is fixedly installed on the inner wall of the regenerated resin box 7. The fixing block 56 is located below the trigger plate 52. A guide cylinder 57 is slidably installed on the trigger plate 52. The top end of the guide cylinder 57 is fixedly connected to the bottom of the watertight plate 51, and the top end is fixedly connected to the fixing block 56. A return spring 58 is sleeved on the guide cylinder 57. The top end of the return spring 58 abuts against the bottom of the watertight plate 51, and the bottom end abuts against the top of the trigger plate 52, for resetting the trigger plate 52.

[0070] In this embodiment, a trigger plate 52 is installed below the watertight plate 51. This trigger plate 52 can slide along the inner wall of the regenerated resin tank 7, and the hoisting line 36 can smoothly pass through it. Simultaneously, a trigger switch 53 is fixedly installed at the bottom of the watertight plate 51, with its trigger end precisely corresponding to the sliding direction of the trigger plate 52. When the watertight top plate 10 is raised into the regenerated resin tank 7 along with the hoisting line 36, its top positioning block 55 precisely engages with the positioning slot 54 at the bottom of the trigger plate 52, thereby stabilizing the position of the watertight top plate 10. At this time, the trigger plate 52 slides upward due to the pushing force of the watertight top plate 10, thereby triggering the trigger switch 53. Once the trigger switch 53 is triggered, the water pump 16 is immediately started, pumping in the regenerated liquid. To ensure that the trigger plate 52 can slide smoothly and accurately, a fixing block 56 is provided below it, and a guide cylinder 57 is slidably mounted on the trigger plate 52. The top of the guide cylinder 57 is fixedly connected to the bottom of the watertight plate 51 and the fixing block 56. In addition, a return spring 58 is fitted on the guide cylinder 57 to ensure that the trigger plate 52 can automatically reset when no external force is applied.

[0071] In another embodiment of the present invention, a solar panel 59 and an electric telescopic rod 60 are hinged to the top of the recycled resin box 7. The output rod of the electric telescopic rod 60 is hinged to the solar panel 59. A power distribution box 61 is fixedly installed on the top of the recycled resin box 7. The power distribution box 61 is connected to the solar panel 59, the water pump 16, the water inlet motor 27, the electric telescopic rod 33, the drive motor 48, the trigger switch 53, and the electric telescopic rod 60.

[0072] In this embodiment, a solar panel 59 and an electric telescopic rod 60 are hinged to the top of the recycled resin tank 7. The solar panel 59 captures solar energy and converts it into electrical energy, providing green and sustainable energy for the entire device. The output rod of the electric telescopic rod 60 is hinged to the solar panel 59, allowing the solar panel 59 to adjust its angle according to the sun's position, thereby maximizing solar energy capture. Simultaneously, a power distribution box 61 is fixedly installed on the top of the recycled resin tank 7. This power distribution box 61 is responsible for distributing the electrical energy generated by the solar panel 59 to various electrical components, including the water pump 16, the water inlet motor 27, the electric telescopic rod 33, the drive motor 48, the trigger switch 53, and the electric telescopic rod 60. This design not only improves energy utilization efficiency but also enables the device to operate more intelligently and autonomously.

[0073] In another embodiment of the present invention, at least two sides of the water flow channel box 1 are provided with silt installation and stabilization mechanisms for inserting into the river silt to stabilize the water flow channel box 1, the baffle plate 3, and the adjusting plate 6. The silt installation and stabilization mechanism includes an installation sleeve 62 fixedly installed on the side of the water flow channel box 1. A silt insertion rod 63 is slidably installed through the installation sleeve 62. A height-fixing bolt 64 for positioning the height of the silt insertion rod 63 is threaded on the installation sleeve 62. Expansion plates 65 are hinged to both opposite sides of the silt insertion rod 63. An adjustment port 66 is opened on the silt insertion rod 63. An adjustment screw 67 is rotatably installed in the adjustment port 66. The top end of the adjustment screw 67 extends to the silt insertion rod. Outside the top of 63, a sliding block 68 is slidably installed inside the adjustment port 66. The sliding block 68 is threaded onto the adjustment screw 67 so that the adjustment screw 67 drives the sliding block 68 to slide up and down along the adjustment port 66. Both sides of the sliding block 68 extend outside the sludge insertion rod 63 and are fixedly installed with a sealing slide plate 69. The two sealing slide plates 69 slide in contact with the two sides of the sludge insertion rod 63 to close the adjustment port 66. The two sealing slide plates 69 are hingedly installed with hinge arms 70. The two hinge arms 70 are hinged to the two expansion plates 65 so that the angle of the expansion plates 65 is adjusted when the sealing slide plates 69 slide. After the sludge is inserted, the expansion plates 65 unfold in parallel.

[0074] In this embodiment, a silt installation stabilization mechanism is designed to ensure the stable installation of the water flow channel box 1, the baffle plate 3, and the regulating plate 6 in the river channel. This silt installation stabilization mechanism includes an installation sleeve 62 fixedly installed on the side of the water flow channel box 1. A silt insertion rod 63 is slidably installed through the installation sleeve 62. By adjusting the height of the silt insertion rod 63 and fixing it with a height-fixing bolt 64, it can adapt to river silt of different depths. Expansion plates 65 are hinged to both sides of the silt insertion rod 63. The sliding of the closed sliding plate 69 can be controlled by the adjusting screw 67 and the sliding block 68 in the adjusting port 66, thereby adjusting the angle of the expansion plate 65. When the silt insertion rod 63 is inserted into the silt, the expansion plate 65 can unfold parallel, increasing the contact area with the silt and improving stability. During the sliding process, the closed sliding plate 69 not only closes the adjusting port 66 but also connects to the expansion plate 65 through the hinged arm 70, achieving synchronous angle adjustment.
