Abstract
Description
Technical Field
[0001] This invention relates to the field of water surface garbage collection technology, specifically to an automatic floating debris collection device using a flow-through method. Background Technology
[0002] In the field of water surface environment management, the efficient collection of floating debris is a key link in ensuring the ecological health of aquatic areas and improving water quality. Currently, the mainstream technologies for collecting floating debris can be divided into three categories: manual dredging, mechanical dredging vessel operations, and fixed automatic collection devices.
[0003] Fixed automatic collection devices mostly employ a flow-through type floating debris collection system. Existing flow-through floating debris collection systems rely on direct flow, primarily by immersing the collection container directly below the water surface or by continuously raising and lowering it to maintain its position below the water surface. The flow is achieved by utilizing the water level difference, and a drain pump continuously discharges water filtered through filter bags or cartridges to maintain the water level difference inside and outside the collection container. However, existing flow-through floating debris collection devices have the following main drawbacks: 1. Existing irrigation-type floating debris collection devices are limited by fixed installation locations and irrigation methods, and can only efficiently collect floating debris on the water surface near the installation location. The location and size of the effective area are fixed, which does not meet the need for efficient cleaning of floating debris in large water areas. In order to facilitate the cleaning of collected floating debris, the main body of the device is usually set on the shore, which further limits the location and size of its effective area. 2. Existing irrigation-type floating debris collection devices generally lack dehydration mechanisms, resulting in high water content in the collected floating debris, which increases the subsequent cleaning and treatment costs. 3. Existing flood-type floating debris collection devices rely on drainage pumps to maintain the water level difference between the inside and outside of the collection container. If the drainage pump stops due to malfunction, maintenance, or power outage, water will continuously flow into the collection container, preventing the formation of a water level difference between the inside and outside. As a result, the floating debris in the collection container will overflow with the water flow, causing the intercepted floating debris to overflow back into the water area. If an anti-overflow structure is added, the cost will increase, and it is highly likely that it will have an adverse effect on the cleaning of floating debris. 4. The drainage pumps of existing irrigation-type floating debris collection devices are only used for drainage. The kinetic energy of the water flow discharged by the drainage pump is wasted, resulting in low energy utilization.
[0004] In summary, existing flood-type floating debris collection devices have drawbacks such as limited coverage, low energy efficiency, high water content in the collected floating debris, and high risk of leakage during shutdown. Summary of the Invention
[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. It mainly provides an automatic floating debris collection device for irrigation, which solves the technical problems mentioned in the background art, such as limited effective water area, low energy utilization, high water content of collected floating debris, and high risk of leakage during shutdown.

[0009] Furthermore, an annular support ring is provided inside the drainage cavity. The support ring is located on the inner wall of the irrigation cylinder. The bottom of the separation filter cylinder is supported on the support ring by a bearing or a friction-reducing pad. The support ring is provided with multiple arc-shaped lower holes that connect the annular gap. The annular gap is connected to the drainage cavity through the arc-shaped lower holes.
[0010] Furthermore, the separating filter cartridge is provided with a siphon hole penetrating its top and bottom, and a plurality of centrifugal chambers arranged around the siphon hole. The siphon hole is coaxial with the drive shaft, and the centrifugal chambers are provided with drainage holes at least on the outer side. The transmission assembly also includes a plurality of torque transmission arms arranged around the siphon hole, with adjacent torque transmission arms spaced apart, and the transmission shaft is connected to the separation filter cartridge through the plurality of torque transmission arms; The top of the separating filter cartridge and around the siphon hole are provided with a docking structure, and the drain end of the siphon pipe can be connected to the siphon hole through the docking structure. The support ring is rotatably provided with an opening and closing switching ring, which has multiple arc-shaped upper holes adapted to the number and shape of the arc-shaped lower holes, and a sealing part capable of sealing the arc-shaped lower holes is formed between adjacent arc-shaped upper holes. The opening and closing switching ring is connected to a switching mechanism, which controls the opening and closing of the arc-shaped lower hole by rotating the opening and closing switching ring.
[0011] Furthermore, the switching mechanism includes a transmission cylinder connecting the limiting ring and the opening / closing switching ring, the opening / closing switching ring being located at the top of the support ring, and the transmission cylinder being rotatably disposed within the annular gap; The top of the limiting ring is provided with a protrusion along the radial direction. The protrusion has an insertion hole. The top of the protrusion has a strip hole that communicates with the insertion hole. A positioning pin is inserted into the insertion hole. An operating handle connected to the positioning pin is movably disposed in the strip hole. The inner wall of the irrigation tube is provided with a first pin hole and a second pin hole for the insertion of the positioning pin. The arc-shaped upper hole is aligned with the arc-shaped lower hole when the positioning pin is aligned with the first pin hole. The sealing part closes the arc-shaped lower hole when the positioning pin is aligned with the second pin hole.
[0012] Furthermore, a support cylinder is connected to the bottom of the support ring and inside the multiple arc-shaped lower holes. The support cylinder is supported on the bottom inner wall of the irrigation cylinder. Multiple torque transmission arms are located inside the support cylinder. The support cylinder is provided with multiple side holes for connecting the siphon hole and the drainage chamber.
[0013] Furthermore, a spare filter cartridge is inserted into the siphon hole, and a support structure for supporting the spare filter cartridge is provided at the lower end of the siphon hole.

[0015] Furthermore, the water-absorbing end of the water-absorbing section is rotatably connected to a wide-mouth pipe with a top opening, and the bottom of the wide-mouth pipe is connected to an anchoring cable located on the vertical line of its center of gravity, with an anchoring object provided at the lower end of the anchoring cable.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

The irrigation tube and the separation filter tube can be set close to the shore, which facilitates the cleaning of the collected floating objects. 3. This invention uses an indirect irrigation method via a siphon tube, which allows the separation filter cartridge to accelerate the discharge of water and the dehydration of floating matter through the centrifugal force generated by its rotation. This meets the needs of large-volume treatment of water bodies with many floating objects and helps to reduce the weight of floating objects in the separation filter cartridge. 4. In this invention, while the water in the irrigation cylinder is discharged by the drainage pump, the hydraulic drive mechanism and transmission components can use the water flow discharged by the drainage pump to drive the separation filter cylinder to rotate, thereby improving the energy utilization rate.

[0020] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0022] Please refer to the appendix carefully. Figure 1-14 An automatic floating debris collection device for irrigation, comprising: The irrigation cylinder 1 has an installation cavity 101 and a drainage cavity 102 arranged sequentially from top to bottom inside. The irrigation cylinder 1 is provided with a drainage pipe 2 that connects to the drainage cavity 102, and the top of the irrigation cylinder 1 is higher than the water surface. A drain pump 3 is connected to a drain pipe 2 and is used to drain water from the drain chamber 102; The siphon 4 has a drain end located in the mounting cavity 101 and a water intake end located in the water area near the water surface below the water surface, with the drain end located below the plane of the water intake end. The separation filter cartridge 5 is rotatably mounted in the mounting cavity 101. The drain end of the siphon tube 4 is located above the separation filter cartridge 5. The separation filter cartridge 5 has multiple drain holes 6 along the circumference. The drain holes 6 are connected to the drain cavity 102 through the mounting cavity 101. The separation filter cartridge 5 uses the centrifugal force generated by rotation to accelerate the water to be discharged through the drain holes 6. The transmission assembly 7 has a transmission shaft 701 coaxially connected to the separation filter cartridge 5. The bottom of the irrigation cylinder 1 is provided with a shaft hole through which the transmission shaft 701 passes. The transmission shaft 701 and the shaft hole are rotatably sealed by a rotary seal. The hydraulic drive mechanism 8 is located outside the irrigation cylinder 1 and connected to the drive shaft 701. While the drainage pump 3 is draining water, it uses the water flow to drive the hydraulic drive mechanism 8 to rotate the separation filter cylinder 5.
[0023] Specifically, before use, connect the suction device, such as a self-priming pump, to the drain end of the siphon pipe 4. After the suction device is started, the air in the siphon pipe 4 is extracted until the siphon pipe 4 is filled with water and begins to siphon. After the siphon pipe 4 begins to siphon, the water containing floating objects enters the separation filter cartridge 5 through the siphon pipe 4. Floating objects smaller than the diameter of the drain hole 6 are trapped in the separation filter cartridge 5. After the drain pump 3 starts, it discharges the water in the drain chamber 102, keeping the water level in the irrigation cylinder 1 below the separation filter cartridge 5. The drain pump 3 drains water through the drain pipe 2 and, guided by the drain pipe 2, impacts the hydraulic drive mechanism 8, thereby driving the separation filter cartridge 5 to rotate through the hydraulic drive mechanism 8 and the transmission component 7. When the separation filter cartridge 5 rotates, the water in the separation filter cartridge 5 will be discharged more quickly under the action of centrifugal force, thus avoiding the overflow of water in the separation filter cartridge 5 due to the inability to discharge water in time when the flow rate of the siphon pipe 4 is large and there are many floating objects on the water surface. This adapts to application scenarios with large flow rates and many floating objects. When the flow rate of the siphon tube 4 is small, and the theoretical drainage volume of the separation filter cartridge 5 when it rotates is greater than the inflow flow rate of the siphon tube 4, even if the water mixed with floating matter is continuously poured into the separation filter cartridge 5, the separation filter cartridge 5 can still accelerate the dehydration of the trapped floating matter.
[0024] Furthermore, since the top of the irrigation cylinder 1 is above the water surface, even if the drainage pump 3 stops, once the liquid level inside the irrigation cylinder 1 is the same as the external water level, the siphon pipe 4 will stop filling the irrigation cylinder 1 with water according to the siphon effect principle. This prevents floating debris from overflowing the irrigation cylinder 1 due to the shutdown of the drainage pump 3. Even when there is a large accumulation of floating debris inside the irrigation cylinder 1 and the height of the portion of the irrigation cylinder 1 above the water surface is relatively small, the overflow of floating debris can still be reduced.
[0025] Preferably, the irrigation cylinder 1 is positioned near the bank to facilitate the cleaning of floating debris collected by the separation filter cylinder 5.
[0026] In summary, the features and beneficial effects of this invention are as follows: 1. The siphon effect of the siphon tube 4 is used to inject water from the water area into the separation filter tube 5 inside the injection tube 1. Compared with the injection-type floating debris collection device, which directly sets the collection container below the water surface for direct injection, it can avoid or reduce the overflow of floating debris into the collection container with the water flow when the drainage pump 3 stops. 2. Water is injected into the separation filter cylinder 5 through the siphon tube 4. Compared with the existing irrigation-type floating debris collection device, the water inlet is fixed and located near the main body of the device. The length of the siphon tube 4 and the position of the water inlet can be flexibly adjusted, which can meet the needs of efficient collection of floating debris in large areas of water. At the same time, the irrigation cylinder 1 and the separation filter cylinder 5 can be set close to the shore, which is convenient for cleaning the collected floating debris. 3. Because the siphon tube 4 is used for indirect irrigation, the centrifugal force generated by the rotation of the separation filter cartridge 5 can accelerate the discharge of water and the dehydration of floating objects in the separation filter cartridge 5, so as to meet the needs of large flow treatment of water areas with many floating objects, and help to reduce the weight of floating objects in the separation filter cartridge 5. 4. While draining water from the irrigation cylinder 1, the drainage pump 3 can drive the separation filter cylinder 5 to rotate through the hydraulic drive mechanism 8 and the transmission component 7, thereby improving the energy utilization rate.
[0027] The hydraulic drive mechanism 8 includes an impeller 801 and a guide shroud 802. The guide shroud 802 is located at the bottom of the irrigation cylinder 1 and has a circular guide cavity. The impeller 801 is located in the guide cavity and connected to the drive shaft 701. The guide shroud 802 has an inlet and an outlet along the tangent of the guide cavity, and the outlet pipe 2 is connected to the inlet.
[0028] The water flow from the pump impacts the impeller 801, causing it to rotate. This rotation, via the transmission assembly 7, drives the separator filter cartridge 5 to rotate. The guide shroud 802 isolates the impeller 801 from the surrounding water, creating a stable vortex at the impeller 801 without interference from turbulent currents. This, in turn, helps improve the rotational speed and stability of the impeller 801, i.e., the separator filter cartridge 5.
[0029] Depending on the capacity or load of the separating filter cartridge 5, the hydraulic drive mechanism 8 and the transmission assembly 7 can be selectively designed with torque optimization. For example, by increasing the torque, the hydraulic drive mechanism 8 can utilize the kinetic energy of water to drive the separating filter cartridge filled with wet floating matter to rotate. In addition, since the separating filter cartridge 5 is located inside the irrigation cylinder 1, the operating environment of the separating filter cartridge 5 is stable, so that after the separating filter cartridge 5 rotates, it can still maintain effective rotation under the action of inertia even if the load gradually increases.
[0030] Preferably, an annular gap is formed between the outer wall of the separating filter cartridge 5 and the inner wall of the irrigation cylinder 1. The annular gap is used to connect the drain hole 6 and the drain cavity 102. A limiting ring 9 is provided at the top of the annular gap at the upper end of the irrigation cylinder 1. The inner diameter of the limiting ring 9 is adapted to the outer diameter of the separating filter cartridge 5. The limiting ring 9 limits the separating filter cartridge 5 to ensure that the separating filter cartridge 5 is coaxial with the drive shaft 701, thereby ensuring that the separating filter cartridge 5 can rotate stably.
[0031] A further optimization of the above embodiment is that an annular support ring 10 is provided inside the drainage chamber 102. The support ring 10 is disposed on the inner wall of the irrigation cylinder 1. The bottom of the separation filter cylinder 5 is supported on the support ring 10 by bearings or friction-reducing pads to avoid or reduce the axial force on the drive shaft 701, thereby facilitating the sealing design between the drive shaft 701 and the shaft hole, as well as the axial positioning design of the drive shaft 701. The support ring 10 is provided with multiple arc-shaped lower holes 11 that connect the annular gap, and the annular gap and the drainage chamber 102 are connected through the arc-shaped lower holes 11.
[0032] A further optimization of the above embodiment is that the separation filter cartridge 5 is provided with a siphon hole 501 that extends through its top and bottom, and a plurality of centrifugal chambers 502 arranged around the siphon hole 501. The siphon hole 501 is coaxial with the drive shaft 701, and the centrifugal chambers 502 are provided with at least a drain hole 6 on the outer side. The transmission assembly 7 also includes a plurality of torque transmission arms 702 arranged around the siphon hole 501, with adjacent torque transmission arms 702 spaced apart, and the transmission shaft 701 is connected to the separation filter cartridge 5 through the plurality of torque transmission arms 702. A docking structure 12 is provided at the top of the separation filter cartridge 5 and around the siphon hole 501, and the drain end of the siphon pipe 4 can be connected to the siphon hole 501 through the docking structure 12. An opening and closing switching ring 13 is rotatably provided on the support ring 10. The opening and closing switching ring 13 has a plurality of arc-shaped upper holes 1301 adapted to the number and shape of the arc-shaped lower holes 11, and a sealing part 1302 capable of sealing the arc-shaped lower holes 11 is formed between adjacent arc-shaped upper holes 1301. The opening and closing switching ring 13 is connected to a switching mechanism 14, which controls the opening and closing of the arc-shaped lower hole 11 by rotating the opening and closing switching ring 13.
[0033] When floating debris collection is required, the drain end of the siphon tube 4 is connected to the docking structure 12, so that the siphon tube 4 is connected to the siphon hole 501. The docking structure 12 has a rotary sealing function to ensure that the siphon tube 4 can remain connected to the rotating separation filter cartridge 5. The opening and closing switching ring 13 is rotated by the switching mechanism 14 until the sealing part 1302 closes the arc-shaped lower hole 11. At this time, only the siphon hole 501 is connected to the drain chamber 102. When the drain pump 3 is working, it draws air from the drain chamber 102, the siphon hole 501 and the siphon tube 4 and discharges the air into the water. After the siphon tube 4 performs siphoning, the drain end of the siphon tube 4 is moved above the centrifuge chamber 502, and the arc-shaped upper hole 1301 of the opening and closing switching ring 13 is aligned with the connecting hole of the support ring 10, so that the water thrown out by the separation filter cartridge 5 flows into the installation chamber 101 through the drain hole 6, the annular gap, the arc-shaped upper hole 1301 and the arc-shaped lower hole 11. At this time, the drain pump 3 discharges the water in the drain chamber 102.
[0034] Among them, the drainage pump 3 can be a self-priming pump. The working principle of the pump is that the pump casing is filled with water or there is water in the pump casing before the pump starts. After starting, the impeller 801 rotates at high speed, causing the water in the impeller 801 channel to flow to the volute. At this time, a vacuum is formed at the inlet, which opens the inlet check valve, and the air in the suction pipe enters the pump, reaches the outer edge through the impeller 801 channel, and is then discharged.
[0035] When it is necessary to further dehydrate the floating matter in each centrifuge chamber 502, when the siphon tube 4 is siphoning, the siphon tube 4 is connected to the siphon hole 501, and the arc-shaped upper hole 1301 of the opening and closing switching ring 13 is aligned with the arc-shaped lower hole 11 of the support ring 10. At this time, since the siphon tube 4 no longer injects water into each centrifuge chamber 502, the floating matter collected in each centrifuge chamber 502 can be further dehydrated under the rotation of the separation filter cartridge 5.
[0036] In addition, to facilitate the cleaning of floating objects collected inside the separation filter cartridge 5, an inner cylinder with multiple drainage holes 6 can be inserted into and limited inside the separation filter cartridge 5, or a filter bag can be installed inside the separation filter cartridge 5 through a bag opening fixing structure.
[0037] Furthermore, the separation filter cartridge 5 and the transmission assembly 7 can be driven by means such as friction drive or magnetic coupling, so that when the inner cylinder needs to be replaced, the drain pump 3 does not need to be stopped. The separation filter cartridge 5 can be stopped, and then the inner cylinder or filter bag can be disassembled and cleaned.
[0038] The separation filter cartridge 5, through the design of multiple centrifugal chambers 502, can achieve the dispersed collection of floating matter, thereby facilitating the dehydration of the floating matter. Moreover, the collected floating matter is located on the periphery of the separation filter cartridge 5, and is subjected to greater centrifugal force, which is conducive to the removal of water. The design of the siphon hole 501 makes it convenient to pour water into the siphon tube 4 so that the siphon tube 4 can perform siphoning.
[0039] The function of the docking structure 12 is to seal the connection between the siphon tube 4 and the siphon hole 501. The docking structure 12 connects the siphon tube 4 and the separation filter cartridge 5 using methods such as plugging, snap-fit, or threading, and assists the sealing ring for sealing. Furthermore, since the siphon tube 4 can be moved and docked manually, or by automated or semi-automated equipment, and the specific structure of the docking structure 12 needs to be adapted to the operation method of the siphon tube 4, the specific structure of the docking structure 12 will not be elaborated upon; the selection will depend on the actual scenario and requirements.
[0040] Preferably, the switching mechanism 14 includes a transmission cylinder 1401 that connects the limiting ring 9 and the opening / closing switching ring 13. The opening / closing switching ring 13 is located at the top of the support ring 10, and the transmission cylinder 1401 is rotatably disposed within the annular gap. The top of the limiting ring 9 is provided with a protrusion 1402 along the radial direction. The protrusion 1402 is provided with an insertion hole 15. The top of the protrusion 1402 is provided with a strip hole 16 that communicates with the insertion hole 15. A positioning pin 1403 is inserted into the insertion hole 15. An operating handle 1404 connected to the positioning pin 1403 is movably provided in the strip hole 16. The inner wall of the irrigation cylinder 1 is provided with a first pin hole 17 and a second pin hole 18 for the insertion of the positioning pin 1403. The arc-shaped upper hole 1301 is aligned with the arc-shaped lower hole 11 when the positioning pin 1403 is aligned with the first pin hole 17. The sealing part 1302 closes the arc-shaped lower hole 11 when the positioning pin 1403 is aligned with the second pin hole 18.
[0041] The protrusion 1402 on the limiting ring 9 facilitates rotation. The positioning pin 1403 switches and positions the opening / closing switching ring 13 by inserting it into the first pin hole 17 and the second pin hole 18, thereby switching the opening and closing state of the arc-shaped lower hole 11 on the support ring 10. Furthermore, to easily determine the opening and closing state of the arc-shaped lower hole 11 on the support ring 10, markings can be made at the first pin hole 17 and the second pin hole 18.
[0042] In addition, by inserting the positioning pin 1403 into the first pin hole 17 and the second pin hole 18, the limiting ring 9 can be limited in the vertical direction. Its advantage is that it facilitates the sealing of the contact surface between the opening and closing switching ring 13 and the support ring 10. For example, elastic sealing gaskets with multiple openings are provided at the bottom of the opening and closing switching ring 13 and the top of the support ring 10. The opening position and opening shape of the elastic sealing gasket are adapted to the arc-shaped lower hole 11 and the arc-shaped upper hole 1301. When it is necessary to insert the positioning pin 1403 into the first pin hole 17 or the second pin hole 18, first rotate the limiting ring 9 so that the protrusion 1402 is aligned with the first pin hole 17 or the second pin hole 18 in the circumferential direction. Then press the limiting ring 9 down so that the positioning pin 1403 is aligned with the first pin hole 17 or the second pin hole 18 in the vertical direction. Insert the positioning pin 1403 into the first pin hole 17 or the second pin hole 18. At this time, the elastic sealing gasket between the opening and closing switching ring 13 and the support ring 10 is compressed, so that the contact surface between the two is sealed.
[0043] In addition, at least three protrusions 1402 can be equally spaced along the circumference of the limiting ring 9, and at least three sets of the first pin hole 17 and the second pin hole 18 are also provided accordingly, so as to ensure a better sealing effect between the opening and closing switching ring 13 and the support ring 10. At the same time, multiple protrusions 1402 also facilitate the operation of the limiting ring 9 to rotate.
[0044] A further optimization of the above embodiment is that a support cylinder 19 is connected to the bottom of the support ring 10 and inside the multiple arc-shaped lower holes 11. The support cylinder 19 assists the support ring 10 in supporting the separation filter cylinder 5. The support cylinder 19 is supported on the bottom inner wall of the irrigation cylinder 1. Multiple torque transmission arms 702 are located inside the support cylinder 19. The support cylinder 19 is provided with multiple side holes 20 for connecting the siphon hole 501 and the drainage chamber 102.
[0045] A further optimization of the above embodiment is that a spare filter cartridge 21 is inserted into the siphon hole 501, and a support structure 22 for supporting the spare filter cartridge 21 is provided at the lower end of the siphon hole 501. The spare filter cartridge 21 includes an outer cylinder 2101 and a conical filter screen 2102 arranged coaxially. The conical filter screen 2102 is conical, and the bottom of the conical filter screen 2102 extends outward and connects to the inner wall of the outer cylinder 2101.
[0046] When the siphon orifice 501 is connected to the siphon pipe 4, the conical filter screen 2102 allows air and water to pass through while blocking floating objects, thus preventing larger floating objects from being sucked into the drainage pump 3 and causing the drainage pump 3 to malfunction. The replaceable design of the spare filter cartridge 21 facilitates the cleaning of floating objects.
[0047] The siphon tube 4 includes a water intake section 401, a lifting section 402, and a drainage section 403 connected in sequence. The lifting section 402 is located at the top of the irrigation tube 1. The water intake end of the water intake section 401 is located in the water surface area below the water surface. The drainage end of the drainage section 403 is located in the installation cavity 101. The water intake section 401 floats in the water through the floating structure 23.
[0048] The lifting section 402 is fixedly installed on the top of the irrigation cylinder 1 by a fixed structure to ensure that the lengths of the water intake section 401 and the drainage section 403 do not change, that is, to ensure that the drainage end of the drainage section 403 is located below the plane where the water intake end of the water intake section 401 is located. The function of the floating structure 23 is to support the water intake section 401 using buoyancy. The floating structure 23 can be a component with equivalent function, such as a float, buoy, or airbag, which can be selected as needed, and will not be described in detail here.
[0049] A further optimization of the above embodiment is that the water-absorbing end of the water-absorbing section 401 is rotatably connected to a wide-mouth pipe 24 with a top opening, and the bottom of the wide-mouth pipe 24 is connected to an anchoring cable 25 located on the vertical line of its center of gravity, and an anchoring object 26 is provided at the lower end of the anchoring cable 25.
[0050] The internal pipe of the wide-mouth pipe 24 is L-shaped, and the wide-mouth pipe 24 is anchored in position by the anchoring cable 25 and the anchor 26 submerged in the water. Since the side of the wide-mouth pipe 24 is rotatably connected to the water intake section 401, and the anchoring cable 25 is located on the vertical line of the center of gravity of the wide-mouth pipe 24, the top opening of the wide-mouth pipe 24 can be kept upward under the action of the gravity of the anchor 26.
[0051] In addition, large floating objects can be prevented from clogging the siphon pipe by adding a filter screen to the wide-mouth pipe 24 or by adding multiple upward-extending fence-like structures around the pipe opening.
[0052] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications to the technical solutions of the present invention by utilizing the methods and techniques disclosed above without departing from the spirit and scope of the present invention. Therefore, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solutions of the present invention shall fall within the protection scope of the technical solutions of the present invention.
