Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The present invention provides a technical solution: a device for cleaning blue algae blooms in rivers and lakes, comprising a hull 1, a mounting groove being provided on the left side of the hull 1, a moving mechanism 2 and a separating mechanism 4 being provided on the inner side of the hull 1, and a gathering mechanism 3 being provided on the left side of the hull 1;

[0039] The gathering portion 32 is located on the left side of the driving portion 31;

[0040] The separation mechanism 4 includes a separation portion 41 and an extraction portion 42;

[0041] The extraction portion 42 is located on the inner side of the separation portion 41 .

[0042] The adjusting part 21 includes a U-shaped plate 211, which is fixedly connected to the rear side of the hull 1. A small waterproof motor 212 is provided on the inner side of the U-shaped plate 211, and the small waterproof motor 212 is fixedly connected to the U-shaped plate 211. A threaded rod 213 is provided on the output end face of the small waterproof motor 212, and the threaded rod 213 is fixedly connected to the small waterproof motor 212. The threaded rod 213 extends through and extends to the inner side of the hull 1, and the threaded rod 213 is threadedly connected to the inner wall of the hull 1.

[0043] The front end face of the threaded rod 213 is rotatably connected to the inner side of the hull 1 through a bearing seat. A threaded plate 214 is sleeved on the surface of the threaded rod 213. The threaded plate 214 is threadedly connected to the threaded rod 213. A side plate 215 is provided on the left side of the threaded plate 214. The side plate 215 is fixedly connected to the threaded plate 214. A retaining ring 216 is provided on the left side of the side plate 215. The retaining ring 216 is fixedly connected to the side plate 215. A collecting pipe 217 is provided on the inner side of the retaining ring 216. The collecting pipe 217 and the retaining ring 216 are engaged with each other.

[0044] The collecting part 22 includes a guide rod 221, which is fixedly connected to the inner side of the hull 1. A slide 222 is provided on the surface of the guide rod 221. The slide 222 is slidingly connected to the guide rod 221. The slide 222 is fixedly connected to the right side of the side panel 215. A conveying hose 223 is provided on the left side of the slide 222, and the conveying hose 223 is connected to the collecting pipe 217.

[0045] The right end surface of the delivery hose 223 is connected to a delivery pump 224 , which is located on the inner side of the hull 1 . The delivery pump 224 is fixedly connected to the inner side of the hull 1 , and the top surface of the delivery pump 224 is connected to a feed pipe 225 .

[0046] Furthermore, this embodiment utilizes a small waterproof motor 212 in the adjustment unit 21 as a power source, driving the connected threaded rod 213 to rotate. As the threaded rod 213 rotates, a force is applied to the threaded plate 214, which is threadedly engaged with the threaded rod 213. This force, in turn, drives the connected side plates 215 and collection tube 217 to move. Assisted by the slide plate 222, the side plates 215 and collection tube 217 slide smoothly along the surface of the guide rod 221, thereby moving the collection tube 217 in a specific direction. Simultaneously, the delivery pump 224 is activated. Upon activation, the delivery pump 224 creates a negative pressure within the collection tube 217's suction range via the delivery hose 223, thereby drawing algae within this range into the collection tube 217 and transporting them through the delivery hose 223 to a designated location for collection. As the collecting tube 217 continuously moves under the action of the moving mechanism 2, algae in a larger range can be fully absorbed and collected;

[0047] Furthermore, this embodiment utilizes the small waterproof motor 212 in the adjustment portion 21 through the moving mechanism 2. The small waterproof motor 212 drives the threaded rod 213, and the threaded rod 213 drives the threaded plate 214. The threaded plate 214 drives the side plate 215 and the collection tube 217 to slide on the surface of the guide rod 221 under the action of the slide plate 222, thereby driving the collection tube 217 to move. At the same time, the delivery pump 224 is started. The delivery pump 224 sucks and collects the algae within the suction range of the collection tube 217 through the delivery hose 223, thereby fully moving, sucking and collecting the algae within the range.

[0048] Example 2:

[0049] See also Figure 1 、 Figure 2 、 Figure 5 , and on the basis of Example 1, it is further obtained that: the driving part 31 includes a protective cover 311, the protective cover 311 is fixedly connected to the hull 1, a small waterproof motor 2 312 is provided on the inner side of the protective cover 311, the small waterproof motor 2 312 is fixedly connected to the protective cover 311, a worm 313 is provided on the output end face of the small waterproof motor 2 312, the worm 313 is fixedly connected to the small waterproof motor 2 312, the front end face of the worm 313 is rotatably connected to the inner side face of the protective cover 311 through the bearing seat 2, the outer end face of the worm 313 is provided with a worm wheel 314, and the worm wheel 314 is meshed with the worm 313.

[0050] The gathering portion 32 includes a rotating rod 321, which is fixedly connected to the worm gear 314. The rotating rod 321 passes through the protective cover 311 and extends to the inner side of the installation groove. The surface of the rotating rod 321 is rotatably connected to the protective cover 311 and the inner wall of the hull 1 through the bearing seat three, and the bottom end face of the rotating rod 321 is rotatably connected to the inner side of the installation groove through the bearing seat four.

[0051] A rotating plate 322 is sleeved on the surface of the rotating rod 321 , and the rotating plate 322 is fixedly connected to the rotating rod 321 . A gathering plate 323 is provided on the left side of the rotating plate 322 , and the gathering plate 323 is fixedly connected to the rotating plate 322 .

[0052] Furthermore, this embodiment utilizes the gathering mechanism 3 and the small waterproof motor 2 312 in the drive unit 31. The small waterproof motor 2 312 serves as a power source and begins to operate. Its output shaft drives the worm 313 connected thereto to rotate. When the worm 313 rotates, the worm wheel 314, which is meshed with the worm 313, begins to rotate under the transmission action of the worm 313. During the rotation of the worm wheel 314, it drives the rotating rod 321 fixed thereto. When the rotating rod 321 rotates, it drives the rotating plate 322 and the gathering plate 323 to move synchronously. Due to the rotation of the rotating rod 321, the angles of the rotating plate 322 and the gathering plate 323 can be changed. By properly controlling the rotation direction and angle of the small waterproof motor 2 312, the gathering plate 323 can swing according to a preset trajectory and angle, gradually gathering the scattered algae within a certain range.

[0053] Furthermore, this embodiment utilizes the gathering mechanism 3 and the small waterproof motor 2 312 in the driving unit 31. The small waterproof motor 2 312 drives the worm 313, and the worm 313 drives the worm gear 314 to engage and rotate. When the worm gear 314 rotates, it drives the rotating rod 321, so that the rotating rod 321 drives the rotating plate 322 and the gathering plate 323 to change their angles, thereby gathering them within a certain range, thereby facilitating suction.

[0054] Example 3:

[0055] See also Figure 1 、 Figure 2 、 Figure 6 , and on the basis of Example 1, it is further obtained that: the separation part 41 includes a collection box 411, a through groove and a card hole are opened on the right side of the collection box 411, the collection box 411 is fixedly connected to the hull 1, and a drainage pipe 412 is provided on the front side of the collection box 411. The drainage pipe 412 extends through and extends to the front side of the hull 1, and a slide groove 413 is provided on the rear side of the drainage pipe 412, and the slide groove 413 is fixedly connected to the inner side of the collection box 411.

[0056] The extraction part 42 includes a screen 421, which is located on the inner side of the slide groove 413. The screen 421 is slidably connected to the slide groove 413. The screen 421 extends through to the right side of the through groove. A sealing baffle 422 is provided on the right side of the screen 421. The sealing baffle 422 is fixedly connected to the screen 421. A clamping rod 423 is fixedly provided on the left side of the sealing baffle 422, and the clamping rod 423 is engaged with the clamping hole.

[0057] Furthermore, this embodiment utilizes the separation mechanism 4 and the collection box 411 in the separation section 41. During the overall operation, the absorbed algae and water mixture is transported to the collection box 411 through the feed pipe 225. After entering the collection box 411, the mixture passes through the screen 421 disposed therein. Because the screen 421 has pores of a specific size, water can pass through the pores of the screen 421 smoothly, while the algae are trapped above the screen 421, thereby achieving a preliminary separation of the algae and clean water. The separated clean water is then discharged into the river through the drain pipe 412 disposed in the collection box 411. After the operation is completed, the separated algae need to be collected and processed by the staff. In this case, the algae above the screen 421 can be directly removed. If the screen 421 becomes clogged due to long-term use or algae accumulation, affecting normal separation operation, the screen 421 needs to be cleaned or replaced. At this point, the staff member pulls the sealing baffle 422 provided on the collection box 411, which moves the screen 421 along with it and simultaneously separates the latching rod 423 from the corresponding latching hole on the collection box 411. After separation, the screen 421 can slide in the preset chute 413 in the collection box 411, and the staff member can smoothly remove the screen 421 from the collection box 411 for cleaning.

[0058] Furthermore, this embodiment uses the separation mechanism 4 and the collection box 411 in the separation part 41. The algae after absorption enters the collection box 411 through the feeding pipe 225, is separated by the screen 421, and the clean water after separation is discharged from the drain pipe 412. After finishing the work, the staff collects the algae on the screen 421. When the screen 421 is blocked, the sealing baffle 422 is pulled, and the sealing baffle 422 drives the screen 421, so that the sealing baffle 422 drives the clamping rod 423 to separate from the clamping hole, thereby sliding the screen 421 from the slide groove 413 in the collection box 411 to remove the collection box 411, thereby realizing the separation of algae and clean water and convenient cleaning of the screen 421.

[0059] When in use, through the gathering mechanism 3, the small waterproof motor 2 312 in the driving part 31 is used, and the small waterproof motor 2 312 starts to operate as a power source, and its output shaft drives the worm 313 connected to it to rotate. When the worm 313 rotates, the worm wheel 314 that is meshed with the worm 313 starts to rotate under the transmission action of the worm 313. During the rotation of the worm wheel 314, it will drive the rotating rod 321 fixed to it. When the rotating rod 321 rotates, it will drive the rotating plate 322 and the gathering plate 323 to move synchronously. The rotation of the rotating rod 321 causes the rotating plate 322 and the gathering plate 323 to change angles. By properly controlling the rotation direction and angle of the small waterproof motor 2 312, the gathering plate 323 can swing according to a preset trajectory and angle, gradually gathering the scattered algae within a certain range. Then, the moving mechanism 2 uses the small waterproof motor 1 212 in the adjustment unit 21 as a power source to drive the connected threaded rod 213 to rotate. When the threaded rod 213 rotates, the threaded plate 214, which is threadedly engaged with the threaded rod 213, is subjected to a force transmitted by the thread. Under the action of the threaded force, the threaded plate 214 drives the connected side plate 215 and the collection pipe 217 to move. At this time, the side plate 215 and the collection pipe 217, assisted by the slide plate 222, slide smoothly along the surface of the guide rod 221, thereby moving the collection pipe 217 in a specific direction. At the same time, the delivery pump 224 is activated. When the delivery pump 224 begins operation, it creates a negative pressure environment within the suction range of the collection tube 217 through the delivery hose 223, thereby sucking the algae within this range into the collection tube 217 and transporting it through the delivery hose 223 to the designated collection box 411 for collection. As the collection tube 217 continuously moves under the action of the movement mechanism 2, it can comprehensively absorb and collect algae within a larger range. After absorption, the algae and water mixture is transported through the separation mechanism 4 and the collection box 411 in the separation unit 41 through the feed pipe 225 during the entire operation process to the collection box 411. Once in the collection box 411, the mixture passes through the screen 421 disposed therein. Since the screen 421 has pores of a specific size, water can pass through the pores of the screen 421 smoothly, while the algae are intercepted above the screen 421, thereby achieving preliminary separation of the algae and clean water. The separated clean water is discharged into the river through the drain pipe 412 provided on the collection box 411. After the work is completed, the staff needs to collect and process the separated algae. At this time, the algae above the screen 421 can be directly removed. When the screen 421 is blocked due to long-term use or algae accumulation, which affects the normal separation work, the screen 421 needs to be cleaned or replaced.At this point, the staff member pulls the sealing baffle 422 provided on the collection box 411, which moves the screen 421 along with it and simultaneously separates the latching rod 423 from the corresponding latching hole on the collection box 411. After separation, the screen 421 can slide in the pre-set chute 413 in the collection box 411, allowing the staff member to smoothly remove the screen 421 from the collection box 411 for cleaning.

[0060] It should be noted that the delivery pump 224, the hull 1, the small waterproof motor 312, and the small waterproof motor 212 (the relevant technologies used have been widely disseminated as public technologies in the industry. Given the wide variety of models and specifications of the delivery pump 224, the hull 1, the small waterproof motor 312, and the small waterproof motor 212, it is difficult to fully describe the specific details of each model here.)

[0061] Furthermore, the Model 213 threaded rod, Model 313 worm gear, and Model 314 worm gear are all manufactured from high-quality materials with excellent corrosion resistance and water resistance. These materials not only effectively resist erosion by various corrosive media but also maintain stable performance in humid or underwater environments, ensuring long-term reliable operation of the equipment.
