[0041] First embodiment:

[0042] Please refer to Figure 1 (Refer to) Figures 2 to 10This application provides a water environment ecological restoration device, which mainly includes a funnel-shaped collection pipe 1, an inclined connecting pipe 2, a pumping pipe 3, a water treatment structure, and a floating structure connected in sequence. The water treatment structure includes a treatment pipe 4. The funnel-shaped collection pipe 1, the inclined connecting pipe 2, the pumping pipe 3, and the treatment pipe 4 are connected in sequence. The opening of the funnel-shaped collection pipe 1 is horizontal, and the inclined connecting pipe 2 is inclined. Its upper port is connected to the small port of the funnel-shaped collection pipe 1, and its lower port is connected to the side port of the pumping pipe 3. The diameter of the trumpet-shaped collecting pipe 1 is larger than that of the inclined connecting pipe 2 and the pumping pipe 3. The heights of the trumpet-shaped collecting pipe 1, the inclined connecting pipe 2, and the pumping pipe 3 decrease sequentially, while the height of the treatment pipe 4 is higher than that of the trumpet-shaped collecting pipe 1. Simultaneously, a rotatable main shaft 8 is installed inside the treatment pipe 4. A mounting sleeve 9 is fitted onto the end of the main shaft 8 away from the pumping pipe 3. Multiple arc-shaped rods 10, spaced apart along the length, are fixedly connected to the mounting sleeve 9, with the bending direction of the arc-shaped rods 10 facing the mounting sleeve 9. Furthermore, the sidewall of the treatment pipe 4... The processing port 7 extends along the curvature of its sidewall. A connecting frame 20 is installed inside the lower part of the processing port 7. Multiple guide rods 21 are connected to the connecting frame 20. One end of each guide rod 21 extends obliquely upward into the gap between two adjacent arc-shaped rods 10. The guide rods 21 and the arc-shaped rods 10 are staggered. The rear edge of the rearmost guide rod 21 is in contact with the front surface of the rotating mesh 11. At the same time, a collection frame 22 is provided on the outside of the processing port 7. The collection frame 22 extends downward and backward towards the processing tube 4. The inclined extension design ensures that collected algae can accumulate towards the rear. A mounting plate 23 is fixedly connected to the side of the collection frame 22. The outer surface of the mounting plate 23 is fixedly connected to the side surface of the treatment pipe 4 via mounting bolts 24. After unscrewing the mounting bolts 24, the mounting plate 23 can be removed for easy maintenance of the collection frame 22. An arc-shaped rod 10 is used to move debris entering the treatment pipe 4 from the funnel-shaped collection pipe 1 onto a guide rod 21. The guide rod 21 scrapes the debris and transports it through the treatment port 7 into the collection frame 22. A suction mechanism is provided at the connection between the treatment pipe 4 and the pumping pipe 3. Floating structures are located on opposite sides of the treatment pipe 4.

[0043] like Figure 10 As shown, when the device is placed in the water, the water in the funnel-shaped collecting pipe 1 is not full and forms a semi-empty part 31, the water in the pumping pipe 3 is full and forms a full part 32, and the water in the treatment pipe 4 is not full and forms an aeration part 33.

[0044] like Figure 5 As shown, at the same time, the front end of the treatment pipe 4 is connected to the transition bucket 6, the front end of the transition bucket 6 is connected to the transition pipe 5, and the front end of the transition pipe 5 is connected to the rear end of the pumping pipe 3, which can ensure that the water flow inside can enter the inside of the treatment pipe 4 from the pumping pipe 3.

[0045] like Figure 3 , Figure 4 As shown, the suction mechanism includes a first protective shell 17 installed in the inner cavity of the treatment pipe 4. A drive motor 16 is fixedly installed inside the first protective shell 17, and the output shaft of the drive motor 16 is driven by a drive shaft 14. The drive shaft 14 is located in the inner cavity of the transition pipe 5, and multiple suction blades 19 are installed at intervals on its peripheral sidewall. The suction blades 19 are located in the inner cavity of the transition pipe 5. The drive motor 16 drives the suction blades 19 to rotate and perform water suction operation through the drive shaft 14. Furthermore, a second protective shell 18 is fixedly connected to the inner wall of the transition hopper 6, and the rear surface of the second protective shell 18 is fixedly connected to the first protective shell 17. The drive shaft 14 passes through the second protective shell 18 and is driven by a transmission belt 15 to the end of the main shaft 8. The drive shaft 14 drives the main shaft 8 to rotate through the transmission belt 15. The first protective shell 17 and the second protective shell 18 can protect the drive motor 16 and the transmission belt 15, preventing floating algae from affecting the operation of the drive motor 16 and the transmission belt 15.

[0046] Meanwhile, a rotating mesh 11 is fitted onto the end of the main shaft 8 furthest from the pumping pipe 3. The rotating mesh 11 is rotatably mounted on the inner circumferential wall of the treatment pipe 4, and the edge of the rotating mesh 11 is rotatably engaged with the inner wall of the treatment pipe 4; and, as Figure 4 As shown, a connecting shaft 12 is connected to the end of the main shaft 8 away from the pumping pipe 3. Multiple striking blades 13 are fixedly connected to the outer surface of the connecting shaft 12. When the main shaft 8 rotates, the striking blades 13 promote the entry of air into the water and simultaneously cause the water to flow backward. Furthermore, as... Figure 2 , Figure 3 As shown, the rear end port of the treatment pipe 4 is fixedly connected to the discharge pipe 30, which is located below the water surface, ensuring that the aeration effect can enter the water.

[0047] Specifically, the floating structure includes two connecting rods 25 and two rigid floating shells 26. One connecting rod 25 has its two ends extending through opposite sides of the pumping pipe 3 and connecting to the two rigid floating shells 26 respectively. The other connecting rod 25 has its two ends extending through opposite sides of the processing pipe 4 and connecting to the two rigid floating shells 26 respectively. Each rigid floating shell 26 includes a lower shell 28, a soft bladder 27, and an upper shell 29 connected sequentially from bottom to top. An inflation nozzle is provided on the upper shell 29. When air is inflated into the inflation nozzle, the lower shell 28 and upper shell 29 move away from each other, pulling open the soft bladder 27, thereby increasing the buoyancy of the lower shell 28, upper shell 29, and soft bladder 27, ensuring that the arrangement depth of the device can be adjusted to a suitable depth.

[0048] like Figure 6As shown, the rear of the guide rod 21 is in contact with the front surface of the rotating net 11. As the rotating net 11 rotates, the floating algae filtered down from the surface will be scraped off by the guide rod 21, ensuring smooth water flow at the rotating net 11.

[0049] It should be noted that when the device is placed in the water, the water in the funnel-shaped collection pipe 1 is not full, so a semi-empty part 31 is formed inside it; the water in the pumping pipe 3 is full and forms a full part 32; the water in the treatment pipe 4 is not full, so an aeration part 33 is formed inside it.

[0050] When using this device, the user places it on the water surface and inflates the inner cavity of the hard shell through the air inlet to adjust the overall buoyancy to a suitable level. The floating state is as follows: the funnel-shaped collection pipe 1 is not full of water, forming a semi-empty section 31; the water pumping pipe 3 is full of water, forming a filled section 32, ensuring smooth pumping; the treatment pipe 4 is not full of water, forming an aeration section 33; and the discharge pipe 30 is below the water surface. During aeration, when the drive motor 16 operates, the drive shaft 14 rotates. Under the action of the transmission belt 15, the main shaft 8 rotates. The rotation of the drive shaft 14 causes the suction blades 19 to rotate and draw water in. Water is drawn into the water pumping pipe 3, and while the funnel-shaped collection pipe 1 is drawing in water, it also draws in algae from the water surface, which is then sent into the treatment pipe 4. The rotating suction blades 19 roughly break up the algae, preventing entanglement and jamming. The main shaft 8... Rotation causes the striking blade 13 to rotate, injecting air into the water and causing water to be discharged from the outlet 34, achieving an aeration effect. Simultaneously, the algae are agitated by the curved rod 10. Due to the curvature of the curved rod 10, the algae slide away from the main shaft 8 during this agitation. Combined with the action of the guide rod 21, the algae on the surface of the curved rod 10 are scraped away by the guide rod 21. The curvature of the curved rod 10 itself allows the algae to be pushed and moved. Finally, most of the algae are scraped off the end of the curved rod 10 and fall onto the surface of the guide rod 21. Because the guide rod 21 is tilted, the algae slide diagonally downwards along its surface and fall into the inner side of the collection frame 22. Since the collection frame 22 is tilted downwards and backwards, the collected algae slide backwards. During later maintenance, when the device floats close to the shore, the collected algae can be easily scooped out from the collection frame 22 using tools, making it convenient to use.

[0051] In summary, the water environment ecological restoration device of this application can pump water from the surface through the pumping pipe 3 and the water treatment structure. Simultaneously, the coordinated action of the arc-shaped rod 10 and the guide rod 21 within the water treatment structure allows for the concentrated collection of suspended algae, facilitating subsequent harvesting and treatment. This convenient operation significantly reduces manual labor, saves time and effort, lowers workload, and improves the efficiency of water environment ecological restoration. Furthermore, the device can float on the water surface through the sequentially connected funnel-shaped collection pipe 1, inclined connecting pipe 2, pumping pipe 3, and water treatment structure, enabling aeration and algae collection at multiple locations on the water surface, further saving time and effort, reducing workload, and improving the efficiency of water environment ecological restoration.

[0052] Second embodiment:

[0053] In this embodiment, a method for ecological restoration of the water environment is provided. This method uses the ecological restoration device for the water environment in the first embodiment to restore the water environment, and mainly includes the following steps:

[0054] S1, Place the above-mentioned water environment ecological restoration device in the water;

[0055] S2, by adjusting the floating structure, the floating state of the water environment ecological restoration device is adjusted to be: the water in the funnel-shaped collection pipe 1 is not full and forms a semi-empty part 31, the water in the pumping pipe 3 is full and forms a full part 32, and the water in the treatment pipe 4 is not full and forms an aeration part 33.

[0056] S3, activate the suction blade 19 in the water treatment structure, and use suction to draw surface water and floating algae from the funnel-shaped collection tube 1 into the treatment tube 4, and then guide them to the collection frame 22 through the cooperation of the arc-shaped rod 10 and the guide rod 21.

[0057] S4, the collection box 22 is regularly salvaged and maintained by staff.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
