Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise.

[0044] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0045] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0046] The terms "parallel" and "perpendicular" used in this application refer to "basically parallel" and "basically perpendicular" in practical operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0047] like Figures 1-8 As shown in the embodiment of this application, the acoustic algae removal vessel includes: a moving mechanism 1, an acoustic algae removal device, and a protective cover assembly 5. The acoustic algae removal vessel is mounted on the moving mechanism 1, which is used to move on the water surface. The moving mechanism 1 can drive the acoustic algae removal vessel to move on the water surface, so that the sound waves emitted by the acoustic algae removal device can cover the area requiring algae removal, thereby achieving algae removal operations.

[0048] The acoustic algae removal device provided in this application embodiment includes: an air compressor 2, a whistle-generating component 3, and an acoustic wave emitting component 4. The air compressor 2, the whistle-generating component 3, and the acoustic wave emitting component 4 are all disposed on the moving mechanism 1 and are all farther away from the water surface than the moving mechanism 1.

[0049] An air compressor 2 is connected to a whistle-generating component 3, which in turn is connected to a sound wave emitting component 4. The air compressor 2 compresses air and discharges the airflow. The airflow passes through the whistle-generating component 3, forming sound waves, which are then emitted towards the algae by the sound wave emitting component 4. The sound waves vibrate in the water, exerting pressure on the algae cells and damaging their cell membranes, thus achieving algae removal through sound waves. In this embodiment, the whistle-generating component 3 can generate low-frequency sound waves targeting algae, achieving algae cell destruction with relatively low power, thus achieving algae removal in an economical and environmentally friendly manner.

[0050] like Figure 1 As shown in the embodiment of this application, the acoustic algae removal vessel includes a protective cover assembly 5, which is slidably connected to the moving mechanism 1. The protective cover assembly 5 can cover the air compressor 2, the whistle-emitting component 3, and the acoustic wave emitting component 4. This allows the protective cover assembly 5 to cover the air compressor 2, the whistle-emitting component 3, and the acoustic wave emitting component 4 when the acoustic algae removal device is not in operation, thereby reducing the impact of the external environment on the working components of the acoustic algae removal device and improving the lifespan of the acoustic algae removal vessel.

[0051] like Figures 1-2 As shown, the protective cover assembly 5 includes a fixed section and a telescopic section with an integral structure, as well as a slide rail slidably connected to the telescopic section. The fixed section is fixedly connected to the moving mechanism 1 to maintain coverage of the air compressor 2, ensuring the source of sound waves. Because the fixed section maintains its covering state, it can be made of a hard shell material to improve the stability of the coverage of the air compressor 2. The slide rail is fixedly connected to the moving mechanism 1 and is distributed along the long side of the moving mechanism 1. The telescopic section is slidably connected to the slide rail to improve the smoothness of the telescopic section's extension and retraction process. This allows the telescopic section to expose the whistle-generating component 3 and the sound wave emitting component 4 when sound wave algae removal is needed, and to promptly cover the whistle-generating component 3 and the sound wave emitting component 4 when not in operation, reducing the influence of the external environment and extending the service life of the sound wave algae removal device.

[0052] To improve the smoothness of the sliding of the telescopic section, pulleys are installed in the telescopic section, and the telescopic section can slide in cooperation with the slide rail through the pulleys.

[0053] In some embodiments, the shield assembly 5 may be a foldable canvas container to improve the flexibility of the shield assembly 5.

[0054] In practice, the acoustic algae removal vessel provided in this application embodiment also includes a drive system 6. The drive system 6 can drive the moving mechanism 1, the air compressor 2, the acoustic emission component 4, and the protective cover component 5. The drive system 6 includes drive components such as a diesel engine, an electric motor, a propeller, and a speed governor for driving the moving mechanism 1 to move forward, backward, and turn, thereby driving the acoustic algae removal device to move.

[0055] The drive system 6 also includes a power component for providing power to the air compressor 2, the acoustic wave emitting component 4 and the shield component 5. The power component can be a power supply component or an engine, etc., which is not limited in this application embodiment.

[0056] In some embodiments, such as Figures 1-2 As shown, the drive system 6 is located on the top surface of the moving mechanism 1, and its protective cover assembly 5 can shield the drive system 6, further improving the service life of the acoustic algae removal vessel.

[0057] In some other embodiments, the drive system 6 is disposed inside the moving mechanism 1 to further reduce the influence of the external environment on the drive system 6 and improve the stability of the operation of the drive system 6.

[0058] like Figures 1-2 As shown, the acoustic wave emitting assembly 4 includes a pitch adjustment assembly 42 and an acoustic wave emitting cover 43, wherein the pitch adjustment assembly 42 is disposed on the moving mechanism 1. The inlet end of the acoustic wave emitting cover 43 is connected to the whistle-generating assembly 3, so that the sound waves generated by the whistle-generating assembly 3 are emitted through the emitting end of the acoustic wave emitting cover 43; the pitch adjustment assembly 42 is connected to the acoustic wave emitting cover 43 and is used to adjust the pitch angle of the acoustic wave emitting cover 43. In this way, by changing the angle between the axis of the acoustic wave emitting cover 43 and the horizontal plane, the pitch adjustment assembly 42 can increase the water area that the sound waves emitted by the acoustic wave emitting cover 43 can cover, thereby increasing the algae removal range and improving the algae removal efficiency; furthermore, the acoustic wave emitting cover 43 can be fixed at a specified angle by the pitch adjustment assembly 42 to target algae removal in a specified area, thereby improving the algae removal effect.

[0059] like Figure 2 As shown, the acoustic wave emitting cover 43 is gradually expanding from its inlet end to its emitting end, so as to enhance the acoustic waves emitted by the acoustic wave emitting cover 43 and further improve the algae removal effect.

[0060] like Figure 3 and Figure 4As shown, the pitch adjustment assembly 42 includes a support frame 420, a transmission component 422, and a first drive component 421. The acoustic wave emitting cover 43 is rotatably mounted on the support frame 420. The first drive component 421 and the support frame 420 are both mounted on the moving mechanism 1 and are relatively fixed. The first end of the transmission component 422 is hinged to the acoustic wave emitting cover 43, and the second end of the transmission component away from the acoustic wave emitting cover 43 is hinged to the output shaft of the first drive component 421. The axis of the first drive component 421 is parallel to the axis of the acoustic wave emitting cover 43, so that the output shaft of the first drive component 421 can drive the second end of the transmission component 422 to move in the horizontal direction. The first end of the transmission component 422 drives the acoustic wave emitting cover 43 to rotate around the hinge position between the acoustic wave emitting cover 43 and the support frame 420, thereby realizing the adjustment of the pitch angle of the acoustic wave emitting cover 43.

[0061] In some other embodiments, the pitch adjustment component 42 can be connected to the acoustic emitting cover 43 via the first drive component 421. The output end of the first drive component 421 extends and retracts in the vertical direction. The acoustic emitting cover 43 is provided with a sliding groove. The output end of the first drive component 421 slides and hinges with the sliding groove on the acoustic emitting cover 43. The extension and retraction of the output end of the first drive component 421 drives the acoustic emitting cover 43 to rotate around the support frame 420, thereby realizing the adjustment of the pitch angle of the acoustic emitting cover 43. This reduces the power transmission process, shortens the time for the first drive component 421 to drive the acoustic emitting cover 43 to rotate, and further improves the algae removal efficiency.

[0062] To facilitate the adjustment of the acoustic wave emitting cover 43 by the first driving component 421 via the transmission component 422, such as Figure 3 and Figure 4 As shown, the hinge position between the acoustic emitting cover 43 and the support frame 420 is located between the hinge position between the acoustic emitting cover 43 and the transmission member 422 and the emitting end of the acoustic emitting cover 43. That is, the hinge position between the transmission member 422 and the acoustic emitting cover 43 is close to the inlet end of the acoustic emitting cover 43. This allows the transmission member 422 to move the inlet end of the acoustic emitting cover 43 within a small range, which in turn allows the emitting end of the acoustic emitting cover 43 to move within a larger range. This reduces the distance that the first driving member 421 needs to drive the second end of the transmission member 422 to move horizontally. This allows for a larger range of adjustment of the pitch angle of the acoustic emitting cover 43 with a smaller movement of the output shaft of the first driving member 421, improving the adjustment efficiency of the pitch angle of the acoustic emitting cover 43 and further improving the algae removal efficiency.

[0063] In practice, the first driving component 421 can be a driving mechanism that can realize telescopic movement, such as an electric push rod or a telescopic cylinder. This application embodiment does not limit this.

[0064] In this embodiment, the acoustic wave emitting cover 43 is supported by a support frame 420. Specifically, as shown in the example... Figure 3

[0065] As shown, the support frame 420 includes vertical rods 4201 and horizontal rods 4202. The vertical rods 4201 are disposed on the moving mechanism 1. There are two vertical rods 4201, which are distributed on both sides of the sound wave emitting cover along the direction perpendicular to the axis of the sound wave emitting cover. There are also two horizontal rods 4202, which correspond one-to-one with the vertical rods 4201. The two horizontal rods are distributed on both sides of the emitting cover along the direction perpendicular to the axis of the sound wave emitting cover. The horizontal rods 4202 connect the corresponding vertical rods 4201 and the outer wall of the sound wave emitting cover 43 to ensure that the sound wave emitting cover 43 has a sealed sound wave emission path and reduce the loss of sound wave energy.

[0066] In order to enable the acoustic wave emitting cover 43 to rotate around the support frame 420, in some examples, one end of the horizontal bar 4202 is fixedly connected to the corresponding vertical bar 4201, which increases the strength of the support frame 420, and the other end of the horizontal bar 4202 is rotatably connected to the outer wall of the acoustic wave emitting cover 43, so that the acoustic wave emitting cover 43 can rotate around the two horizontal bars 4202, which improves the flexibility of the rotation process.

[0067] In some other embodiments, one end of the crossbar 4202 is fixedly connected to the outer wall of the acoustic wave emitting cover 43, and the other end of the crossbar 4202 is rotatably connected to the corresponding vertical bar 4201, so that the crossbar 4202 and the acoustic wave emitting cover 43 can rotate synchronously around the hinge point of the crossbar 4202 and the vertical bar 4201, thereby improving the stability of the rotation process.

[0068] like Figure 2 As shown, the acoustic wave emitting assembly 4 also includes a horizontal adjustment assembly 41, which is disposed on the moving mechanism 1. The pitch adjustment assembly 42 is disposed on the moving mechanism 1 via the horizontal adjustment assembly 41. The horizontal adjustment assembly 41 can drive the pitch adjustment assembly 42 and the acoustic wave emitting cover 43 to rotate synchronously, with the rotation axis aligned with the vertical direction; for example, the rotation axis is parallel to the vertical direction. This further expands the water area that the acoustic waves emitted by the acoustic wave emitting cover 43 can cover, further increasing the algae removal range and improving algae removal efficiency.

[0069] It should be noted that the horizontal adjustment component 41 and the pitch adjustment component 42 can be adjusted independently of the acoustic wave emitting cover 43, or they can be adjusted together. For example, the horizontal adjustment component 41 can be used to adjust the acoustic wave emitting cover 43 to locate the algae. Then, based on the area of ​​the algae and its distance from the acoustic wave emitting cover 43, the pitch adjustment component 42 can be adjusted to ensure that the sound waves emitted by the acoustic wave emitting cover 43 accurately cover the algae, thereby improving the algae removal efficiency and effect, and enhancing the flexibility of the acoustic wave emitting cover 43 in actual use.

[0070] like Figure 3 and Figure 5 As shown, the horizontal adjustment assembly 41 includes a base 40, a turntable 410, and a second drive component 411. The turntable 410 and the base 40 are rotatably connected, and the pitch adjustment assembly 42 is disposed on the turntable 410. The base 40 is fixed to the moving mechanism 1, ensuring that both the horizontal adjustment assembly 41 and the pitch adjustment assembly 42 can move stably with the moving mechanism 1. When the pitch adjustment assembly 42 includes a first drive component 421 and a support frame 420, both the first drive component 421 and the support frame 420 in the pitch adjustment assembly 42 are fixed on the turntable 410. Specifically, the vertical rod 4201 of the support frame 420 is fixed on the turntable 410 to support the horizontal rod 4202 and the sound wave emitting cover 43, so that when the turntable 410 rotates, it can synchronously drive the pitch adjustment component 42 and the sound wave emitting cover 43 to rotate; the second drive component 411 is fixedly connected to the base 40, and drives the turntable 410 to rotate around the rotation axis that is consistent with the vertical direction, so as to increase the range of sound waves emitted by the sound wave emitting cover 43.

[0071] like Figure 5 As shown, the output shaft of the second drive component 411 is fixedly connected to the drive gear 412, and the outer circumferential surface of the turntable 410 is provided with gear teeth 414. The drive gear 412 meshes with the gear teeth 414 to realize that the second drive component 411 drives the turntable 410 to rotate. By transmitting power through the drive gear 412 and the gear teeth 414, the rotational speed of the second drive component 411 can be reduced, and the stability of the sound wave emitting cover 43 during rotation can be improved.

[0072] In practice, the second drive component 411 can be a synchronous motor, an asynchronous motor, or other rotating motor, but this application embodiment does not limit this.

[0073] In this embodiment, the horizontal adjustment component 41 can also be disposed on the pitch adjustment component 42, that is, the horizontal adjustment component 41 is disposed on the moving mechanism 1 via the pitch adjustment component 42. In this way, the horizontal adjustment component 41 drives the acoustic wave emitting cover 43 to rotate, with the rotation axis aligned with the vertical direction; for example, the rotation axis is parallel to the vertical direction. During the process of adjusting the pitch angle of the acoustic wave emitting cover 43, the horizontal adjustment component 41 moves synchronously with the acoustic wave emitting cover 43. For example, the horizontal adjustment component 41 and the acoustic wave emitting cover 43 are disposed on a rotatable platform, which is rotatably disposed on the moving mechanism 1. The pitch adjustment component 42 is connected to the platform, and the pitch adjustment component 42 drives the platform to rotate to adjust the platform's pitch angle, thereby causing the horizontal adjustment component 41 and the acoustic wave emitting cover 43 to move synchronously, achieving the purpose of adjusting the pitch angle of the acoustic wave emitting cover 43.

[0074] In this embodiment, the air compressor 2 is connected to the whistle-producing assembly 3 via an air supply pipe 20, such as... Figures 1-2As shown, the air supply pipe 20 connects the inlet end of the whistle sound-generating component 3 and the exhaust port of the air compressor 2. The air supply pipe 20 transmits the airflow discharged from the air compressor 2, ensuring the stability of the airflow transmission.

[0075] Since the whistle-generating component 3 is connected to the sound wave emitting cover 43, in order to ensure the adjustment of the sound wave emitting cover 43, in some embodiments, the outlet end of the whistle-generating component 3 is connected to the inlet end of the sound wave emitting cover 43 through a flexible pipe. During the movement of the sound wave emitting cover 43, the flexible pipe deforms to ensure the smooth movement of the sound wave emitting cover 43.

[0076] In some other embodiments, the outlet end of the whistle-generating component 3 is fixedly connected to the inlet end of the sound wave emitting cover 43, so that the sound waves generated by the whistle-generating component 3 are directly emitted through the sound wave emitting cover 43, reducing the propagation distance of the sound waves and reducing the energy loss of the sound waves. In order to ensure that both the whistle-generating component 3 and the sound wave emitting cover 43 can move, the air supply pipe 20 connecting the air compressor 2 and the whistle-generating component 3 is a flexible pipe, so that the air supply pipe 20 can deform and ensure the smooth movement of the sound wave emitting cover 43.

[0077] The whistle-generating assembly 3 includes an inlet pipe 31, a vortex generating section 32, a resonant cavity 33, and a diffuser pipe 34, such as Figure 6 As shown, the inlet pipe 31, vortex generating part 32, resonant cavity 33, and diffuser pipe 34 are sequentially connected along the same axis. The exhaust port of the air compressor 2 is connected to the inlet end of the inlet pipe 31, so that the high-speed airflow discharged from the air compressor 2 enters the whistle sound generating assembly 3 through the inlet pipe 31, and forms a sound wave after passing through the vortex generating part 32 and the resonant cavity 33 in sequence. In this embodiment, the airflow forms a sound wave through the whistle sound generating assembly 3. Each part of the whistle sound generating assembly 3 is only a mechanical structure, so that the sound wave formation process does not require an additional matching circuit, which can form a more stable sound wave and improve the stability of the sound wave generation.

[0078] To increase the intensity of sound waves, such as Figure 6 As shown, the resonant cavity 33 is connected to the diffuser tube 34, which diffuses the sound waves generated by the resonant cavity 33, thereby increasing the intensity of the sound waves.

[0079] It should be noted that the whistle sound-producing component 3 also includes a housing 30, such as Figure 6 As shown, the inlet pipe 31, the eddy current generating part 32, the resonant cavity 33 and the diffuser pipe 34 are all located inside the housing 30. The housing 30 provides protection for the inlet pipe 31, the eddy current generating part 32, the resonant cavity 33 and the diffuser pipe 34, further ensuring the stability of the sound wave formation process.

[0080] Because the airflow needs to reach a resonant frequency to resonate and form sound waves, the airflow discharged from air compressor 2 needs to be accelerated. For example... Figure 7 As shown, the inlet pipe 31 includes a large-diameter section 310 and a small-diameter section 312. The inlet end of the large-diameter section 310 is connected to the exhaust port of the air compressor 2, and the outlet end of the small-diameter section 312 is connected to the vortex generating part, so that the airflow enters through the large-diameter section 310 and exits through the small-diameter section 312. The diameter of the large-diameter section 310 is larger than the diameter of the small-diameter section 312. In this way, the cross-sectional area through which the airflow passes from the large-diameter section 310 to the small-diameter section 312 is reduced. When the flow rate of the airflow through the inlet pipe 31 is a fixed value, the velocity of the airflow is increased, thus achieving the acceleration of the airflow passing through the inlet pipe 31.

[0081] Because there is a certain difference in cross-sectional area between the large-diameter section 310 and the small-diameter section 312, in order to reduce the impact of airflow on the small-diameter section 312, the inlet pipe 31 includes a tapering section 311, such as... Figure 7 As shown, the tapering section 311 connects the outlet end of the large diameter section 310 and the inlet end of the small diameter section, and the tapering section 311 tapes from the large diameter section 310 to the small diameter section 312. In this way, the tapering section 311 provides a buffer and reduces the impact of the airflow on the small diameter section 312.

[0082] like Figure 7 As shown, the large-diameter section 310, the tapering section 311, and the small-diameter section 312 are distributed sequentially along the same axis, so that the speed of the airflow can gradually increase as it passes through the large-diameter section 310, the tapering section 311, and the small-diameter section 312, thus ensuring the stability of the airflow during acceleration.

[0083] In order for the airflow to have an angle with the axis of the resonant cavity 33 when it enters the resonant cavity 33, such as Figure 6 As shown, a vortex generating unit 32 is connected to the outlet end of the inlet pipe 31 to generate vortices. Specifically, the vortex generating unit 32 includes a vortex cavity 320, the inlet end of which is connected to the outlet end of the small-diameter section 312, so that the high-speed airflow generated by the inlet pipe 31 is discharged into the vortex cavity 320 and forms vortices through the vortex cavity 320. The outlet end of the vortex cavity 320 is connected to a resonant cavity 33, so that the vortex is discharged into the resonant cavity 33 and resonates within the resonant cavity 33 to form sound waves.

[0084] In order to enable the high-speed airflow to form vortices within the vortex cavity 320, such as Figure 8 As shown, the inner wall of the vortex cavity 320 is provided with guide vanes 321. The guide vanes 321 are distributed along the axial direction of the vortex cavity 320, so that the airflow rotates in the vortex cavity 320 under the guidance of the guide vanes 321 and moves towards the outlet end of the vortex cavity 320, thereby forming a vortex.

[0085] In some embodiments, a plurality of guide vanes 321 are provided on the inner wall of the vortex cavity 320. The plurality of guide vanes 321 are distributed sequentially along the axial direction of the vortex cavity 320 and are distributed along the same helical line, so that the airflow rotates under the guidance of the plurality of guide vanes 321 after entering the vortex cavity 320. Furthermore, by adjusting the number of guide vanes 321 and the angle between the guide vanes 321 and the inner wall of the vortex cavity 320, the intensity of the formed vortex can be adjusted, thereby expanding the intensity range of the formed sound wave.

[0086] In some other embodiments, such as Figure 8 As shown, a guide vane 321 is provided on the inner wall of the vortex cavity 320. The guide vane 321 is integral and spiral-shaped, so that the airflow rotates under the guidance of the guide vane 321 after entering the vortex cavity 320, thereby improving the stability of vortex formation.

[0087] It should be noted that, due to the large impact force of high-speed airflow, the guide vane 321 is made of wear-resistant metal materials, such as titanium alloy, hard alloy, and high manganese steel, so that the guide vane 321 can withstand the impact of high-speed airflow, extend the service life of the guide vane 321, and further improve the stability of vortex formation.

[0088] like Figure 6 As shown, the outlet end of the eddy current generating part 32 is connected to the resonant cavity 33 so that the eddy current generated by the eddy current generating part 32 resonates in the resonant cavity 33 to form sound waves. Specifically, the resonant cavity 33 includes a resonant cavity body, the inlet end of the resonant cavity body is connected to the outlet end of the eddy current cavity 320, and a reflective layer or reflective structure for reflecting the eddy current is provided inside the resonant cavity body.

[0089] For example, the resonant cavity is provided with a smooth layer for reflecting eddy currents. After the high-speed eddy current enters the resonant cavity, it vibrates in the resonant cavity under the reflection of the smooth layer. When the high-speed eddy current vibrates in the resonant cavity to the resonant frequency, the eddy current forms a sound wave.

[0090] In some other embodiments, the resonant cavity is provided with a reflective structure for reflecting eddy currents, such as a mirror or reflector. After the eddy currents enter the resonant cavity, they vibrate and form sound waves under the action of the reflective structure. The reflective structure is detachably installed in the resonant cavity, and the intensity of the formed sound waves can be adjusted by replacing different reflective structures, thereby further expanding the intensity range of the formed sound waves.

[0091] In order to increase the frequency response range of eddy currents within the resonant cavity, such as Figure 6 As shown, the resonant cavity is cylindrical, which can increase the range of reflection angles of eddy currents within the resonant cavity and further increase the frequency response range of eddy currents within the resonant cavity.

[0092] In some other embodiments, the resonant cavity is spherical, which can further increase the range of angles at which eddies are reflected within the resonant cavity, thereby further increasing the frequency response range of the generated sound waves.

[0093] Of course, since the size and shape of the resonant cavity can affect the frequency of the sound wave, the resonant cavity can also be a square cylinder, a hemisphere, etc. in order to form sound waves of different frequencies. This application does not limit this.

[0094] In order to increase the intensity of sound waves, such as Figure 6 As shown, the outlet of the resonant cavity 33 is connected to the diffuser tube 34, which is used to diffuse the sound waves generated in the resonant cavity 33. The diffuser tube 34 is a gradually expanding tube, and the diffuser tube 34 gradually expands from the inlet end of the diffuser tube 34 to the outlet end of the diffuser tube 34. After the sound waves are generated from the resonant cavity 33, they are discharged from the inlet end of the diffuser tube 34 to the outlet end of the diffuser tube 34, which enhances the intensity of the sound wave.

[0095] like Figures 1-2 As shown, the outlet end of the diffuser tube 34 in the whistle sound-generating assembly 3 is connected to the inlet end of the sound wave emitting cover 43, so that the sound wave with enhanced intensity is emitted through the sound wave emitting cover 43, which further improves the algae removal effect.

[0096] In practice, the embodiments of this application also include a control system. The control system is communicatively connected to the moving mechanism 1, the horizontal adjustment component 41, the pitch adjustment component 42, the protective cover component 5, and the air compressor 2 to adjust the above-mentioned components. Of course, manual adjustment is also possible, and the embodiments of this application do not limit this.

[0097] Before the acoustic algae removal vessel provided in this embodiment of the application begins operation, the drive system 6 connects the moving mechanism 1, the air compressor 2, the horizontal adjustment component 41, and the pitch adjustment component 42, and maintains the protective cover component 5 covering the aforementioned components in the non-operating state. In the area requiring algae removal, the drive system 6 drives the telescopic section of the protective cover component 5 to extend or retract, exposing the acoustic algae removal device and initiating its operation. The air compressor 2 is activated, and the airflow discharged from the air compressor 2 is directed to the whistle-generating component 3 through the air supply pipe 20. Within the whistle-generating component 3, the airflow sequentially passes through the inlet pipe 31, the vortex generating part 32, and the resonant cavity 33, forming sound waves. The sound waves generated by component 3 are emitted towards the algae through the sound wave emitting cover 43 to achieve sound wave algae removal. When algae removal is required in different areas, the driving mechanism 1 is moved to move the sound wave algae removal device to the designated area. The horizontal adjustment component 41 is adjusted to position the sound wave emitting cover 43 to the algae. Then, according to the area of ​​the algae and the distance from the sound wave emitting cover 43, the pitch adjustment component 42 is adjusted so that the sound waves emitted by the sound wave emitting cover 43 can accurately cover the algae. After the sound wave algae removal is completed, the protective cover component 5 is promptly used to cover the sound wave algae removal device to reduce the impact of the external environment and improve the service life of the sound wave algae removal vessel.
