[0044] 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.

[0045] like Figure 1 As shown in the embodiment of this application, the acoustic algae removal device includes: an air compressor 1, a whistle-generating component 2, and a sound wave emitting component 3. The air compressor 1 is connected to the whistle-generating component 2, and the whistle-generating component 2 is connected to the sound wave emitting component 3. The air compressor 1 compresses air and discharges airflow. After the airflow passes through the whistle-generating component 2, it forms sound waves. The sound wave emitting component 3 emits the sound waves towards the algae. The sound waves vibrate in the water, generating pressure on the algae cells and damaging the algae cell membranes, thereby achieving acoustic algae removal. In this embodiment, the whistle-generating component 2 can generate low-frequency sound waves targeting algae, achieving algae cell destruction with low power, thus achieving algae removal in an economical and environmentally friendly manner.

[0046] like Figure 1As shown, the acoustic wave emitting assembly 3 includes a pitch adjustment assembly 32 and an acoustic wave emitting cover 33. The inlet end of the acoustic wave emitting cover 33 is connected to the whistle-generating assembly 2, so that the sound waves generated by the whistle-generating assembly 2 are emitted through the emitting end of the acoustic wave emitting cover 33. The pitch adjustment assembly 32 is connected to the acoustic wave emitting cover 33 and is used to adjust the pitch angle of the acoustic wave emitting cover 33. In this way, by changing the angle between the axis of the acoustic wave emitting cover 33 and the horizontal plane, the pitch adjustment assembly 32 can increase the water area that the sound waves emitted by the acoustic wave emitting cover 33 can cover, thereby increasing the algae removal range and improving the algae removal efficiency. Furthermore, the acoustic wave emitting cover 33 can be fixed at a specified angle by the pitch adjustment assembly 32 to target algae removal in a specific area, thus improving the algae removal effect.

[0047] like Figure 1 As shown, the acoustic wave emitting cover 33 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 33 and further improve the algae removal effect.

[0048] like Figure 2 and Figure 3 As shown, the pitch adjustment assembly 32 includes a support frame 320, a transmission component 322, and a first drive component 321. The acoustic wave emitting cover 33 is rotatably mounted on the support frame 320. The first drive component 321 and the support frame 320 are relatively fixed. The first end of the transmission component 322 is hinged to the acoustic wave emitting cover 33, and the second end of the transmission component away from the acoustic wave emitting cover 33 is hinged to the output shaft of the first drive component 321. The axis of the first drive component 321 is parallel to the axis of the acoustic wave emitting cover 33, so that the output shaft of the first drive component 321 can drive the second end of the transmission component 322 to move in the horizontal direction. The first end of the transmission component 322 drives the acoustic wave emitting cover 33 to rotate around the hinge position between the acoustic wave emitting cover 33 and the support frame 320, thereby realizing the adjustment of the pitch angle of the acoustic wave emitting cover 33.

[0049] In some other embodiments, the pitch adjustment component 32 can be connected to the acoustic emitting cover 33 via the first drive component 321. The output end of the first drive component 321 extends and retracts in the vertical direction. The acoustic emitting cover 33 is provided with a sliding groove. The output end of the first drive component 321 slides and hinges with the sliding groove on the acoustic emitting cover 33. The extension and retraction of the output end of the first drive component 321 drives the acoustic emitting cover 33 to rotate around the support frame 320, thereby realizing the adjustment of the pitch angle of the acoustic emitting cover 33. This reduces the power transmission process, shortens the time for the first drive component 321 to drive the acoustic emitting cover 33 to rotate, and further improves the algae removal efficiency.

[0050] To facilitate the adjustment of the acoustic wave emitting cover 33 by the first driving component 321 via the transmission component 322, such as Figure 2 and Figure 3As shown, the hinge position between the acoustic emitting cover 33 and the support frame 320 is located between the hinge position between the acoustic emitting cover 33 and the transmission member 322 and the emitting end of the acoustic emitting cover 33. That is, the hinge position between the transmission member 322 and the acoustic emitting cover 33 is close to the inlet end of the acoustic emitting cover 33. This allows the emitting end of the acoustic emitting cover 33 to move a large range of motion by moving the inlet end of the acoustic emitting cover 33 by the transmission member 322 within a small range. This reduces the distance that the first driving member 321 needs to drive the second end of the transmission member 322 to move horizontally. This allows for a large range of adjustment of the pitch angle of the acoustic emitting cover 33 by moving the output shaft of the first driving member 321 within a small distance, improving the adjustment efficiency of the pitch angle of the acoustic emitting cover 33 and further improving the algae removal efficiency.

[0051] In practice, the first driving component 321 can be a drive mechanism that can realize telescopic movement, such as an electric push rod or a telescopic cylinder. This application embodiment does not limit this.

[0052] In this embodiment, the acoustic wave emitting cover 33 is supported by a support frame 320. Specifically, as shown in the example... Figure 2 As shown, the support frame 320 includes two vertical rods 3201 and two horizontal rods 3202. There are two vertical rods 3201, which are distributed on both sides of the sound wave emitting hood along a direction perpendicular to the axis of the sound wave emitting hood. There are also two horizontal rods 3202, which correspond one-to-one with the vertical rods 3201. The two horizontal rods are distributed on both sides of the emitting hood along a direction perpendicular to the axis of the sound wave emitting hood. The horizontal rods 3202 connect the corresponding vertical rods 3201 and the outer wall of the sound wave emitting hood 33 to ensure that the sound wave emitting hood 33 has a sealed sound wave emission path and reduce the loss of sound wave energy.

[0053] In order to enable the acoustic wave emitting cover 33 to rotate around the support frame 320, in some examples, one end of the horizontal bar 3202 is fixedly connected to the corresponding vertical bar 3201, which increases the strength of the support frame 320, and the other end of the horizontal bar 3202 is rotatably connected to the outer wall of the acoustic wave emitting cover 33, so that the acoustic wave emitting cover 33 can rotate around the two horizontal bars 3202, which improves the flexibility of the rotation process.

[0054] In some other embodiments, one end of the crossbar 3202 is fixedly connected to the outer wall of the acoustic wave emitting cover 33, and the other end of the crossbar 3202 is rotatably connected to the corresponding vertical bar 3201, so that the crossbar 3202 and the acoustic wave emitting cover 33 can rotate synchronously around the hinge point of the crossbar 3202 and the vertical bar 3201, thereby improving the stability of the rotation process.

[0055] like Figure 1As shown, the acoustic wave emitting assembly 3 also includes a horizontal adjustment assembly 31, and a pitch adjustment assembly 32 is disposed on the horizontal adjustment assembly 31. The horizontal adjustment assembly 31 can drive the pitch adjustment assembly 32 and the acoustic wave emitting cover 33 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 33 can cover, further increasing the algae removal range and improving the algae removal efficiency.

[0056] It should be noted that the horizontal adjustment component 31 and the pitch adjustment component 32 can be adjusted independently of the acoustic wave emitting cover 33, or they can be adjusted together. For example, the horizontal adjustment component 31 can be used to adjust the acoustic wave emitting cover 33 to locate the algae. Then, based on the area of ​​the algae and its distance from the acoustic wave emitting cover 33, the pitch adjustment component 32 can be adjusted to ensure that the sound waves emitted by the acoustic wave emitting cover 33 accurately cover the algae, thereby improving the algae removal efficiency and effect, and enhancing the flexibility of the acoustic wave emitting cover 33 in actual use.

[0057] like Figure 2 and Figure 4 As shown, the horizontal adjustment assembly 31 includes a base 30, a turntable 310, and a second drive component 311. The turntable 310 and the base 30 are rotatably connected, and the pitch adjustment assembly 32 is disposed on the turntable 310. When the pitch adjustment assembly 32 includes a first drive component 321 and a support frame 320, both the first drive component 321 and the support frame 320 in the pitch adjustment assembly 32 are fixed on the turntable 310. Specifically, the vertical rod 3201 of the support frame 320 is fixed on the turntable 310 to support the horizontal rod 3202 and the acoustic wave emitting cover 33, so that when the turntable 310 rotates, it can synchronously drive the pitch adjustment assembly 32 and the acoustic wave emitting cover 33 to rotate; the second drive component 311 is fixedly connected to the base 30, and drives the turntable 310 to rotate around a rotation axis consistent with the vertical direction through the second drive component 311, so as to increase the range of sound waves emitted by the acoustic wave emitting cover 33.

[0058] like Figure 4 As shown, the output shaft of the second drive component 311 is fixedly connected to the drive gear 312, and the outer circumferential surface of the turntable 310 is provided with gear teeth 314. The drive gear 312 meshes with the gear teeth 314 to realize that the second drive component 311 drives the turntable 310 to rotate. By transmitting power through the drive gear 312 and the gear teeth 314, the rotational speed of the second drive component 311 can be reduced, and the stability of the acoustic wave emitting cover 33 during rotation can be improved.

[0059] In practice, the second drive component 311 can be a synchronous motor, an asynchronous motor, or other rotating motor, and this application embodiment does not limit this.

[0060] In this embodiment, the horizontal adjustment component 31 can also be disposed on the pitch adjustment component 32. In this case, the horizontal adjustment component 31 drives the acoustic wave emitting cover 33 to rotate, with the rotation axis aligned with the vertical direction; for example, the rotation axis is parallel to the vertical direction. During the adjustment of the pitch angle of the acoustic wave emitting cover 33, the horizontal adjustment component 31 moves synchronously with the acoustic wave emitting cover 33. For example, the horizontal adjustment component 31 and the acoustic wave emitting cover 33 are disposed on a rotatable platform, and the pitch adjustment component 32 is connected to the platform. The pitch adjustment component 32 drives the platform to rotate to adjust the platform's pitch angle, thereby causing the horizontal adjustment component 31 and the acoustic wave emitting cover 33 to move synchronously, achieving the purpose of adjusting the pitch angle of the acoustic wave emitting cover 33.

[0061] In this embodiment of the application, the air compressor 1 is connected to the whistle-producing assembly 2 via the air supply pipe 10, such as... Figure 1 As shown, the air supply pipe 10 connects the inlet end of the whistle generator assembly 2 and the exhaust port of the air compressor 1. The air supply pipe 10 transmits the airflow discharged from the air compressor 1, ensuring the stability of the airflow transmission.

[0062] Since the whistle-generating component 2 is connected to the sound wave emitting cover 33, in order to ensure the adjustment of the sound wave emitting cover 33, in some embodiments, the outlet end of the whistle-generating component 2 is connected to the inlet end of the sound wave emitting cover 33 through a flexible pipe. During the movement of the sound wave emitting cover 33, the flexible pipe deforms to ensure the smooth movement of the sound wave emitting cover 33.

[0063] In some other embodiments, the outlet end of the whistle-generating component 2 is fixedly connected to the inlet end of the sound wave emitting cover 33, so that the sound waves generated by the whistle-generating component 2 are directly emitted through the sound wave emitting cover 33, 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 2 and the sound wave emitting cover 33 can move, the air supply pipe 10 connecting the air compressor 1 and the whistle-generating component 2 is a flexible pipe, so that the air supply pipe 10 can deform and ensure the smooth movement of the sound wave emitting cover 33.

[0064] The whistle generating assembly 2 includes an inlet pipe 21, an eddy current generating section 22, a resonant cavity 23, and a diffuser pipe 24, such as Figure 5As shown, the inlet pipe 21, vortex generating part 22, resonant cavity 23, and diffuser pipe 24 are sequentially connected along the same axis. The exhaust port of the air compressor 1 is connected to the inlet end of the inlet pipe 21, so that the high-speed airflow discharged from the air compressor 1 enters the whistle sound generating assembly 2 through the inlet pipe 21, and forms a sound wave after passing through the vortex generating part 22 and the resonant cavity 23 in sequence. In this embodiment, the airflow forms a sound wave through the whistle sound generating assembly 2. Each part of the whistle sound generating assembly 2 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.

[0065] To increase the intensity of sound waves, such as Figure 5 As shown, the resonant cavity 23 is connected to the diffuser tube 24, which diffuses the sound waves generated by the resonant cavity 23, thereby increasing the intensity of the sound waves.

[0066] It should be noted that the whistle sound-producing component 2 also includes a housing 20, such as Figure 5 As shown, the inlet pipe 21, the eddy current generating part 22, the resonant cavity 23, and the diffuser pipe 24 are all located inside the housing 20. The housing 20 provides protection for the inlet pipe 21, the eddy current generating part 22, the resonant cavity 23, and the diffuser pipe 24, further ensuring the stability of the sound wave formation process.

[0067] Because the airflow needs to reach a resonant frequency to resonate and form sound waves, the airflow discharged from air compressor 1 needs to be accelerated. For example... Figure 6 As shown, the inlet pipe 21 includes a large-diameter section 210 and a small-diameter section 212. The inlet end of the large-diameter section 210 is connected to the exhaust port of the air compressor 1, and the outlet end of the small-diameter section 212 is connected to the vortex generating part, so that the airflow enters through the large-diameter section 210 and exits through the small-diameter section 212. The diameter of the large-diameter section 210 is larger than the diameter of the small-diameter section 212. In this way, the cross-sectional area through which the airflow passes from the large-diameter section 210 to the small-diameter section 212 is reduced. When the flow rate of the airflow through the inlet pipe 21 is a fixed value, the velocity of the airflow is increased, thus accelerating the airflow through the inlet pipe 21.

[0068] Because there is a certain difference in cross-sectional area between the large-diameter section 210 and the small-diameter section 212, in order to reduce the impact of airflow on the small-diameter section 212, the inlet pipe 21 includes a tapering section 211, such as... Figure 6 As shown, the tapering section 211 connects the outlet end of the large diameter section 210 and the inlet end of the small diameter section, and the tapering section 211 tapes from the large diameter section 210 to the small diameter section 212. In this way, the tapering section 211 provides a buffer and reduces the impact of the airflow on the small diameter section 212.

[0069] like Figure 6As shown, the large-diameter section 210, the tapering section 211, and the small-diameter section 212 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 210, the tapering section 211, and the small-diameter section 212, thus ensuring the stability of the airflow during acceleration.

[0070] In order for the airflow to have an angle with the axis of the resonant cavity 23 when it enters the resonant cavity 23, such as Figure 5 As shown, a vortex generating unit 22 is connected to the outlet end of the inlet pipe 21 to generate vortices. Specifically, the vortex generating unit 22 includes a vortex cavity 220, the inlet end of which is connected to the outlet end of the small-diameter section 212, so that the high-speed airflow generated by the inlet pipe 21 is discharged into the vortex cavity 220 and forms vortices through the vortex cavity 220. The outlet end of the vortex cavity 220 is connected to a resonant cavity 23, so that the vortex is discharged into the resonant cavity 23 and resonates within the resonant cavity 23 to form sound waves.

[0071] In order to enable the high-speed airflow to form vortices within the vortex cavity 220, such as Figure 7 As shown, the inner wall of the vortex cavity 220 is provided with guide vanes 221. The guide vanes 221 are distributed along the axial direction of the vortex cavity 220, so that the airflow rotates in the vortex cavity 220 under the guidance of the guide vanes 221 and moves towards the outlet end of the vortex cavity 220, thereby forming a vortex.

[0072] In some embodiments, such as Figure 7 As shown, multiple guide vanes 221 are provided on the inner wall of the vortex cavity 220. The multiple guide vanes 221 are distributed sequentially along the axial direction of the vortex cavity 220 and are distributed along the same helical line so that the airflow rotates under the guidance of the multiple guide vanes 221 after entering the vortex cavity 220. Furthermore, by adjusting the number of guide vanes 221 and the angle between the guide vanes 221 and the inner wall of the vortex cavity 220, the intensity of the formed vortex can be adjusted, thereby expanding the intensity range of the formed sound wave.

[0073] In some other embodiments, a guide vane 221 is provided on the inner wall of the vortex cavity 220. The guide vane 221 is integral and spiral-shaped, so that the airflow rotates under the guidance of the guide vane 221 after entering the vortex cavity 220, thereby improving the stability of vortex formation.

[0074] It should be noted that, due to the large impact force of high-speed airflow, the guide vane 221 is made of wear-resistant metal materials, such as titanium alloy, hard alloy, and high manganese steel, so that the guide vane 221 can withstand the impact of high-speed airflow, extend the service life of the guide vane 221, and further improve the stability of vortex formation.

[0075] like Figure 5As shown, the outlet end of the eddy current generator 22 is connected to the resonant cavity 23 so that the eddy current generated by the eddy current generator 22 resonates in the resonant cavity 23 to form a sound wave. Specifically, the resonant cavity 23 includes a resonant cavity body, the inlet end of the resonant cavity body is connected to the outlet end of the eddy current cavity 220, and the interior of the resonant cavity body is provided with a reflective layer or reflective structure for reflecting the eddy current.

[0076] 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.

[0077] 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.

[0078] In order to increase the frequency response range of eddy currents within the resonant cavity, such as Figure 5 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.

[0079] 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.

[0080] 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.

[0081] To increase the intensity of sound waves, such as Figure 5 As shown, the outlet of the resonant cavity 23 is connected to the diffuser tube 24, which is used to diffuse the sound waves generated in the resonant cavity 23. The diffuser tube 24 is a gradually expanding tube, and the diffuser tube 24 gradually expands from the inlet end of the diffuser tube 24 to the outlet end of the diffuser tube 24. After the sound waves are generated in the resonant cavity 23, they are discharged from the inlet end of the diffuser tube 24 to the outlet end of the diffuser tube 24, which enhances the intensity of the sound wave.

[0082] like Figure 1 As shown, the outlet end of the diffuser tube 24 in the whistle sound-generating assembly 2 is connected to the inlet end of the sound wave emitting cover 33, so that the enhanced sound wave is emitted through the sound wave emitting cover 33, further improving the algae removal effect.

[0083] The acoustic algae removal device provided in this application embodiment also includes an acoustic sensor 6, which can detect the intensity of the acoustic waves. In this way, the intensity of the acoustic waves can be adjusted through the feedback of the acoustic sensor 6, so that different intensities of algae removal can be carried out in different areas according to the actual situation.

[0084] Specifically, the intensity of the sound waves is adjusted through the control system 4. The control system 4 includes a controller and a data processor that is communicatively connected to the controller. The data processor is also communicatively connected to the sound wave sensor 6, the horizontal adjustment component 31, and the pitch adjustment component 32. It converts the electrical signal of the sound wave detected by the sound wave sensor 6 into a digital signal. The controller is connected to the air compressor 1. After judging the digital signal processed by the data processor, it issues control commands to the air compressor 1 according to the actual situation, adjusting parameters such as the exhaust pressure, exhaust flow rate, exhaust speed, and operating frequency of the air compressor 1, thereby adjusting the intensity of the generated sound waves. Furthermore, the control system 4 controls the first drive component 321 of the pitch adjustment component 32 and the second drive component 311 of the horizontal adjustment component 31 to adjust the sound wave emission range of the sound wave emitting cover 33.

[0085] Specifically, adjusting the exhaust pressure of the air compressor can regulate the pressure of the output airflow. Higher exhaust pressure creates a stronger airflow impact, thus increasing the intensity of the sound waves. Exhaust flow rate refers to the volume of gas discharged by the air compressor per unit time. Increasing the exhaust flow rate allows more gas to be released into the environment quickly per unit time, thus increasing the intensity of the sound waves. Exhaust velocity refers to the speed at which the airflow exits the compressor. Increasing the exhaust velocity results in a stronger airflow impact and faster air molecule vibration, thus increasing the intensity of the sound waves. When using an air compressor with an adjustable operating frequency, the operating frequency can affect the repetition rate and intensity of the airflow pulses, thereby indirectly affecting the intensity of the sound waves.

[0086] In practice, the acoustic algae removal device provided in this application embodiment also includes a power supply component 5, which provides electrical energy to the control system 4, air compressor 1, acoustic sensor 6, horizontal adjustment component 31, and pitch adjustment component 32. For example, the power supply component 5 includes a solar panel and an energy storage device connected to the solar panel via a cable, saving costs. The energy storage device, connected to the control system 4, air compressor 1, acoustic sensor 6, horizontal adjustment component 31, and pitch adjustment component 32 via a cable, can provide a stable voltage, ensuring the stability of the acoustic algae removal device's operation.

[0087] Of course, power can also be supplied by other power supply components 5, such as generators, transformers and other power generation equipment. This application embodiment does not limit this.

[0088] Before the acoustic algae removal device provided in this embodiment of the application operates, firstly, the power supply component 5 is connected to the control system 4, air compressor 1, acoustic sensor 6, horizontal adjustment component 31, and pitch adjustment component 32 to provide electrical energy. The control system 4 is connected to the air compressor 1, acoustic sensor 6, horizontal adjustment component 31, and pitch adjustment component 32 to prepare for detection and adjustment. After preparation, the air compressor 1 is started. The airflow discharged from the air compressor 1 is discharged to the whistle sound-generating component 2 through the air supply pipe 10. The airflow passes through the inlet pipe 21 in sequence in the whistle sound-generating component 2. Sound waves are generated after the vortex generator 22 and the resonant cavity 23. The sound waves generated by the whistle sound-generating component 2 are emitted towards the algae through the sound wave emitting cover 33 to achieve sound wave algae removal. When algae removal is required in different areas, the horizontal adjustment component 31 can be controlled by the control system 4 to adjust the sound wave emitting cover 33 to position the algae. Then, according to the area of ​​the algae and the distance from the sound wave emitting cover 33, the pitch adjustment component 32 can be controlled by the control system 4 to ensure that the sound waves emitted by the sound wave emitting cover 33 accurately cover the algae, thereby improving the algae removal efficiency and effect.
