Description

Technical Field

[0001] This invention relates to the field of water pollution control technology, and in particular to an ultrasonic algae removal vessel for river and lake water environments. Background Technology

[0002] An ultrasonic algae removal vessel is a mobile floating platform equipped with an ultrasonic wave generation and transmission system. It uses the physical method of ultrasonic wave cavitation effect to destroy the structure of algal cells, causing algae to lose their buoyancy and inhibiting their growth, thereby reducing the concentration of algae in the water and providing emergency treatment for algal blooms. Its core principle is to utilize the shock waves, jets, and radiation pressure generated by ultrasonic waves in a liquid to precisely target algal cells, causing them to lose buoyancy and sink to the bottom, gradually becoming inactive due to their inability to photosynthesize. Furthermore, the entire process involves no chemical additives, minimizing the impact on the aquatic ecosystem.

[0003] A search revealed Chinese patent CN118579891A, which discloses an ultrasonic algae-removing vessel for emergency treatment of algal blooms. This is a catamaran with a diversion channel. Along the front of the hull, corresponding to the diversion channel, are an array of hydrogen peroxide dosers, an array of rotating stirring components, an array of ultrasonic transmitters, an electrically controlled door, and a propeller. It only requires ultrasonic vibration to cause algae to lose their buoyancy and settle to the bottom, while simultaneously serving as food for aquatic organisms without causing water pollution. It boasts high algae removal efficiency and is well-suited for emergency treatment of algal blooms. However, this solution still has the following shortcomings in practical use: In algae control operations, ultrasonic transmitters must be fully submerged in the water to be treated to ensure effective transmission and action of ultrasonic energy. Natural water bodies (especially eutrophic waters prone to algal blooms) commonly contain suspended sediment, dead algae, aquatic organism secretions, and other organic and inorganic pollutants. These substances easily adhere to and accumulate on the surface and outer shell of the ultrasonic transducer. If not cleaned regularly, a dense layer of contaminants will form on the transmitter surface, weakening the penetration efficiency of ultrasonic waves and reducing the overall effectiveness and efficiency of algae removal. Furthermore, the adhered contaminants may cause corrosion of the transmitter shell or localized scaling of the transducer, shortening the equipment's lifespan and potentially leading to equipment malfunction due to uneven energy transmission and localized high-frequency resonance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that the ultrasonic transmitter needs to be submerged in water for use, and its surface may be covered with pollutants. If it is not cleaned for a long time, it will affect its use effect. To this end, we propose an ultrasonic algae removal boat for river and lake water environment.

In conjunction with the brush bristles and the rinsing nozzle, impurities on the outer wall of the algae removal head are automatically removed. No manual disassembly and cleaning is required, reducing maintenance costs and avoiding the impact of impurity residue on the ultrasonic algae removal effect. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] Reference Figure 1-9 As shown, the present invention provides a technical solution: an ultrasonic algae removal vessel for river and lake water environments, comprising an ultrasonic algae removal vessel hull 11 and an algae removal port 12 opened at the bottom of the ultrasonic algae removal vessel hull 11. An algae removal box 13 corresponding to the position of the algae removal port 12 is fixedly installed on the inner wall of the ultrasonic algae removal vessel hull 11. A partition plate 14 is fixedly installed on the inner side of the algae removal box 13. A plurality of algae removal chambers 15 are arranged on the inner side of the partition plate 14. An ultrasonic algae removal head 25 is arranged inside the algae removal chamber 15. A retractable and retractable structure for adjusting the depth of the ultrasonic algae removal head 25 is arranged on the inner side of the algae removal box 13. A guide structure corresponding to the ultrasonic algae removal head 25 is arranged on the inner side of the algae removal chamber 15. A cleaning component for cleaning the outer wall of the ultrasonic algae removal head 25 is arranged on the inner side of the algae removal chamber 15. A linkage component that cooperates with the guide structure to drive the cleaning component is arranged on the inner side of the algae removal chamber 15. The winding and unwinding structure includes a shaft 21 rotatably mounted on the inner wall of the algae removal box 13. A winding and unwinding motor 22 for driving the shaft 21 is fixedly mounted on the side of the algae removal box 13. Several reels 23 corresponding to the algae removal chamber 15 are fixedly fitted on the outer wall of the shaft 21. A pull rope 24 is provided on the inner side of the reel 23. The pulling end of the pull rope 24 passes through the partition plate 14 and is fixedly connected to the top of the ultrasonic algae removal head 25. Two rinsing nozzles 26 for rinsing the ultrasonic algae removal head 25 are symmetrically arranged on the inner top surface of the algae removal chamber 15.

[0022] In use, the ultrasonic algae removal vessel 11 can be placed in the water pollution area where algae need to be treated. The ultrasonic algae removal vessel can float on the water and use the ultrasonic technology of the ultrasonic algae removal head 25 to treat the algae in the water pollution area. Specifically, the operator can turn on the winding motor 22 to drive the shaft 21 to rotate. When the shaft 21 rotates, it can drive several reels 23 on it to rotate synchronously. When the reels 23 rotate, they can unwind the inner pull rope 24. When the pull rope 24 is unwound, the ultrasonic waves at the pulling end of the pull rope 24 will cause the algae to be unwound. The ultrasonic algae removal head 25 has a certain weight, so when the rope 24 is unwound, the ultrasonic algae removal head 25 can move downwards and out of the algae removal port 12 into the water under the action of gravity. The staff can adjust the position of the ultrasonic algae removal head 25 according to the depth of water pollution and algae treatment required. When the ultrasonic algae removal head 25 moves to the treatment depth, it can be turned on to treat the algae in the water pollution area through ultrasonic technology. The working principle and control method of the ultrasonic algae removal head 25 are existing mature technologies, and will not be described in detail here.

[0023] Reference Figure 4-6 As shown, the guiding structure includes a guide groove 31 opened on the inner wall of the algae removal chamber 15, a guide block 32 slidably installed on the inner wall of the guide groove 31, a support rod 33 fixedly installed on the side of the guide block 32, a guide ring 34 fixedly installed at the end of the support rod 33, and a pull rope 24 is set on the inner side of the guide ring 34. The cleaning assembly includes an alignment frame 45 symmetrically arranged inside the algae removal chamber 15 and adapted to the ultrasonic algae removal head 25. A guide rod 46 is provided through the top surface of the alignment frame 45. Mounting plates 47 are fixedly installed at both ends of the guide rod 46. A cleaning semi-ring body 48 is fixedly installed on the side of the mounting plate 47. A support structure for supporting the alignment frame 45 is provided inside the algae removal chamber 15. The supporting structure includes two symmetrically opened grooves 41 on the inner wall of the algae removal chamber 15. A slider 42 is slidably installed on the inner wall of the groove 41. A return spring 43 is fixedly installed between the side of the slider 42 and the inner wall of the groove 41. A support rod 44 is fixedly installed on the side of the slider 42. The alignment frame 45 is fixedly connected to the end of the support rod 44. A connecting plate 49 is fixedly installed at the end of the cleaning semi-ring 48. Two telescopic guide rods 410 are symmetrically fixedly installed on the inner top surface of the algae removal chamber 15. A top plate 411 is fixedly installed at the telescopic end of the two telescopic guide rods 410. Two transmission plates 412 are symmetrically hinged to the bottom surface of the top plate 411. The bottom end of the transmission plate 412 is hinged to the top surface of the support rod 44.

[0024] When the ultrasonic algae removal head 25 moves out of the algae removal chamber 15 via the pull rope 24, the guide block 32, support rod 33, and guide ring 34 can move downwards along the guide groove 31 with the ultrasonic algae removal head 25 under its own weight. When the support rod 33 moves downwards, the top plate 411 can move downwards synchronously under the action of gravity and the tension of the two return springs 43, pushing the two transmission plates 412. When the transmission plates 412 are pushed, they can tilt and push the two alignment frames 45 to slide along the slide groove 41 via the support rod 44 and the slider 42, so that the two alignment frames 45 slide in a direction away from each other. The cleaning semi-ring 48 on the alignment frame 45 can be separated from the ultrasonic algae removal probe, and the ultrasonic algae removal head 25 can be lowered normally for use. After the ultrasonic algae removal head 25 has completed the algae treatment work in this area, it can be wound up and unwound. Motor 22 is turned on to wind up the pull rope 24, which in turn drives the ultrasonic algae removal head 25 to reset. When the ultrasonic algae removal head 25 moves into the algae removal port 12 during reset, the ultrasonic algae removal head 25 can push the guide ring 34, so that the guide ring 34, support rod 33 and guide block 32 can slide upward along the guide groove 31. When the guide block 32 moves to the top of the guide groove 31 with the ultrasonic algae removal head 25, the support rod 33 can push the top plate 411, so that the telescopic guide rod 410 is shortened. When the top plate 411 is pushed upward, it can pull the two transmission plates 412. Through the transmission plates 412, the two support rods 44 can be pulled closer to each other, so that the two alignment frames 45 can be aligned. At this time, the cleaning half ring 48 on the alignment frame 45 can be aligned synchronously and located on the outer wall of the ultrasonic algae removal head 25.

[0025] Reference Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9As shown, the linkage assembly includes a reciprocating screw 51 rotatably mounted on the top surface of the algae removal chamber 15. A semi-threaded opening for screwing the reciprocating screw 51 is provided on the side of the connecting plate 49. A driven bevel gear 52 is fixedly mounted on the bottom end of the reciprocating screw 51. A fixing plate 53 is fixedly mounted on the inner wall of the algae removal chamber 15. A rotating shaft 54 ​​is rotatably mounted on the side of the fixing plate 53. A driving bevel gear 56 that meshes with the driven bevel gear 52 is fixedly mounted on the end of the rotating shaft 54. A transmission gear 55 is mounted on the outer wall of the rotating shaft 54 ​​through a one-way bearing. A torsion spring 57 is mounted on the end of the rotating shaft 54 ​​away from the driving bevel gear 56. The two ends of the torsion spring 57 are fixedly connected to the fixing plate 53 and the rotating shaft 54, respectively. A drive structure is provided on the support rod 33. The drive structure includes a connecting rod 61 rotatably mounted on the bottom surface of the support rod 33. A drive rack 62 that meshes with the transmission gear 55 is fixedly mounted on the end of the connecting rod 61 away from the support rod 33. A torsion spring 63 is fitted on the end of the connecting rod 61, and the two ends of the torsion spring 63 are fixedly connected to the support rod 33 and the connecting rod 61 respectively. A touch rod 64 is fixedly mounted on the end of the connecting rod 61 near the support rod 33. A top block 65 that matches the touch rod 64 is fixedly mounted on the inner wall of the algae removal chamber 15 at the bottom of the guide groove 31. The cross-sectional shape of the top block 65 is set as a right trapezoid.

[0026] When the guide block 32 descends to the bottom of the guide groove 31, as the guide block 32 continues to descend, the contact rod 64 at the end of the connecting rod 61 can contact the top block 65. Under the action of the cross-sectional shape of the top block 65, the contact rod 64 can be pushed, causing the contact rod 64 to drive the connecting rod 61 and the drive rack 62 to rotate, thereby rotating the connecting rod 61 out of the area below the ultrasonic algae removal head 25 without affecting the continued descent of the ultrasonic algae removal head 25. As the connecting rod 61 and the drive rack 62 move downward with the guide block 32, the drive rack 62 can mesh with the transmission gear 55 and drive the transmission gear 55 to rotate. The direction is the free direction of the one-way bearing, so the transmission gear 55 cannot drive the rotating shaft 54 ​​to rotate when it rotates; when the ultrasonic algae removal head 25 is reset, it can push the guide ring 34, so that the guide ring 34, support rod 33 and guide block 32 can slide upward along the guide groove 31. In the initial stage, the contact rod 64 can separate from the top block 65. At this time, under the action of the torsion spring 63, the connecting rod 61 and the drive rack 62 can reverse and reset. The connecting rod 61 can be located below the ultrasonic algae removal head 25. As the pull rope 24 continues to pull the ultrasonic algae removal head 25, the drive rack 62 at the end of the connecting rod 61 can mesh with the transmission gear 55. The transmission gear 55 rotates in the direction that is the locking direction of the one-way bearing. Therefore, when the transmission gear 55 rotates, it drives the rotating shaft 54 ​​and the drive bevel gear 56 to rotate, and compresses and stores the torsion spring 57. When the two alignment frames 45 are aligned, the connecting plates 49 at the ends of the two cleaning semi-rings 48 can also be aligned and screwed to the reciprocating screw 51. When the alignment frames 45 and connecting plates 49 are in place, the ultrasonic algae removal head 25 is fully reset, and the drive rack 62 separates from the transmission gear 55. At this time, under the action of the torsion spring 57, the rotating shaft 54 ​​and the drive bevel gear 56 can reverse, and through the driven bevel gear 52, drive... The reciprocating screw 51 rotates, and when it rotates, it drives the connecting plate 49 and the cleaning half-ring 48 to slide back and forth along the alignment frame 45 via the guide rod 46. The complete cleaning ring composed of the two sets of cleaning half-rings 48 can clean the outer wall of the ultrasonic algae removal head 25 through the bristles on the inner wall. The cleaning liquid sprayed by the flushing nozzle 26 can remove impurities from the outer wall of the ultrasonic algae removal head 25, so as to avoid affecting the effect of the ultrasonic algae removal head 25 on the treatment of water pollution and algae. The flushing nozzle 26 can be connected to the water pump and water tank for liquid supply. This is a mature existing technology and will not be described in detail here. It is not shown in the figure.

[0027] Working principle: During use, the ultrasonic algae removal vessel 11 can be placed in the water pollution area where algae need to be treated. The ultrasonic algae removal vessel can float on the water and use the ultrasonic technology of the ultrasonic algae removal head 25 to treat the algae in the water pollution area. Specifically, the operator can turn on the winding motor 22 to drive the shaft 21 to rotate. When the shaft 21 rotates, it can drive several reels 23 on it to rotate synchronously. When the reels 23 rotate, they can unwind the inner pull rope 24. When the pull rope 24 is unwound, the pull end of the pull rope 24 is pulled. The ultrasonic algae removal head 25 has a certain weight, so when the rope 24 is unwound, the ultrasonic algae removal head 25 can move downwards and out of the algae removal port 12 into the water under the action of gravity. The staff can adjust the position of the ultrasonic algae removal head 25 according to the depth of water pollution algae treatment. When the ultrasonic algae removal head 25 moves to the treatment depth, the ultrasonic algae removal head 25 can be turned on to treat the algae in the water pollution area through ultrasonic technology. The working principle and control method of the ultrasonic algae removal head 25 are existing mature technologies, and will not be elaborated on here. When the ultrasonic algae removal head 25 moves out of the algae removal chamber 15 via the pull rope 24, the guide block 32, support rod 33, and guide ring 34 can move downwards along the guide groove 31 with the ultrasonic algae removal head 25 under its own weight. When the support rod 33 moves downwards, the top plate 411 can move downwards synchronously under the action of gravity and the tension of the two return springs 43, pushing the two transmission plates 412. When the transmission plates 412 are pushed, they can tilt and push the two alignment frames 45 to slide along the slide groove 41 via the support rod 44 and the slider 42, so that the two alignment frames 45 slide in a direction away from each other. The cleaning semi-ring 48 on the alignment frame 45 can be separated from the ultrasonic algae removal probe, and the ultrasonic algae removal head 25 can descend normally for use. After the guide block 32 descends... When the guide block 32 continues to descend to the bottom of the guide groove 31, the contact rod 64 at the end of the connecting rod 61 can contact the top block 65. Under the action of the cross-sectional shape of the top block 65, the contact rod 64 can be pushed, causing the contact rod 64 to drive the connecting rod 61 and the drive rack 62 to rotate, thereby rotating the connecting rod 61 and the drive rack 62 out of the direct line of sight of the ultrasonic algae removal head 25, without affecting the continued descent of the ultrasonic algae removal head 25. During the process of the connecting rod 61 and the drive rack 62 moving downward with the guide block 32, the drive rack 62 can mesh with the transmission gear 55 and drive the transmission gear 55 to rotate. This rotation direction is the free direction of the one-way bearing, so the transmission gear 55 cannot drive the rotating shaft 54 ​​to rotate when it rotates. After the ultrasonic algae removal head 25 completes the algae treatment work in this area, the winding motor 22 can be turned on to wind up the pull rope 24, thereby driving the ultrasonic algae removal head 25 to reset. When the ultrasonic algae removal head 25 moves into the algae removal port 12 during reset, it can push the guide ring 34, allowing the guide ring 34, support rod 33, and guide block 32 to slide upward along the guide groove 31. Initially, the contact rod 64 can separate from the top block 65. At this time, under the action of the torsion spring 63, the connecting rod 61 and the drive rack 62 can reverse and reset. The connecting rod 61 can be located directly below the ultrasonic algae removal head 25. As the pull rope 24 continues to pull the ultrasonic algae removal head 25, the drive rack 62 at the end of the connecting rod 61 meshes with the transmission gear 55, which can drive the transmission gear 55. Rotation, in the direction of locking of the one-way bearing, allows the transmission gear 55 to rotate, which in turn drives the shaft 54 ​​and the bevel gear 56 to rotate, and compresses and stores the torsion spring 57. When the guide block 32 moves to the top of the guide groove 31 with the ultrasonic algae removal head 25, the support rod 33 can push the top plate 411, causing the telescopic guide rod 410 to shorten. When the top plate 411 is pushed upward, it can pull the two transmission plates 412. Through the transmission plates 412, the two support rods 44 can be pulled closer to each other, thereby aligning the two alignment frames 45. At this time, the cleaning half-rings 48 on the alignment frames 45 can be aligned synchronously and located on the outer wall of the ultrasonic algae removal head 25. At the same time, the connecting plates 49 at the ends of the two cleaning half-rings 48 can also be aligned and screwed to the reciprocating screw 51 through the screw hole. When the alignment frame 45 and connecting plate 49 are in place, the ultrasonic algae removal head 25 is fully reset, and the drive rack 62 separates from the transmission gear 55. At this time, under the action of the torsion spring 57, the rotating shaft 54 ​​and the drive bevel gear 56 can reverse, and drive the reciprocating screw 51 to rotate through the driven bevel gear 52. When the reciprocating screw 51 rotates, it can drive the connecting plate 49 and the cleaning half-ring 48 to slide back and forth along the alignment frame 45 through the guide rod 46. The complete cleaning ring composed of the two sets of cleaning half-rings 48 can clean the outer wall of the ultrasonic algae removal head 25 through the bristles on the inner wall. The cleaning liquid sprayed by the flushing nozzle 26 can remove the impurities on the outer wall of the ultrasonic algae removal head 25, so as to avoid affecting the effect of the ultrasonic algae removal head 25 on the treatment of water pollution and algae. The flushing nozzle 26 can be connected to the water pump and water tank for liquid supply. This is an existing mature technology, which will not be described in detail here, and is not shown in the figure.

[0028] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
