Description

Technical Field

[0001] This utility model relates to the field of cyanobacteria control technology, specifically to a device for controlling cyanobacterial blooms. Background Technology

[0002] Cyanobacterial blooms significantly increase the frequency of eutrophication in water bodies, posing a major challenge to human industrial production and daily life. Ultrasonic methods are commonly used to control cyanobacterial blooms. These methods utilize the high-frequency oscillation characteristics of ultrasound waves to disrupt the cellular structure of cyanobacteria through the acoustic effects produced when sound waves propagate in water, thereby achieving the goal of removing cyanobacterial blooms.

[0003] Existing cyanobacterial bloom treatment devices typically involve attaching an ultrasonic generator to a floating buoy, using the ultrasonic waves emitted by the generator to control the algae. While these devices are effective, they also have several drawbacks. The treatment range at any given location is limited, and to treat the algae in the next area, the ultrasonic generator must be manually moved to the next location within the water, making them inconvenient. Utility Model Content

[0004] To address the aforementioned deficiencies, the technical problem to be solved by this utility model is to provide a device for controlling cyanobacterial blooms, which can move within the water body and increase the range of ultrasonic treatment for cyanobacteria.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A device for controlling cyanobacterial blooms includes a chassis. Several floating plates are fixedly connected to the upper part of the chassis. A propeller is rotatably mounted on the lower part of the chassis, with the axis of the propeller oriented laterally. A drive ring is rotatably mounted on the top of the chassis, with the axis of the drive ring oriented vertically. The distance from the end of each floating plate furthest from the chassis to the chassis is less than the radius of the drive ring. The chassis contains a first drive mechanism and a second drive mechanism. The first drive mechanism drives the drive ring to rotate, and the second drive mechanism drives the propeller to rotate. An ultrasonic generator is mounted on the chassis.

[0007] By adopting the above scheme, during use, the second drive mechanism drives the propeller to rotate, thereby moving the housing within the water area. This changes the planar position of the ultrasonic generator in the water, thus increasing the range of cyanobacteria control achieved by the ultrasonic generator. Since the first drive mechanism can drive the drive ring to rotate, and the distance from the end of the float away from the housing to the housing is less than the radius of the drive ring, when the entire device moves to the boundary of the water area, the drive ring contacts the boundary. The reaction force after the drive ring contacts the boundary causes the housing to deflect, thus changing the propulsion direction of the propeller and consequently changing the movement direction of the entire device. Because the propulsion direction of the propeller can be changed, the ultrasonic generator can move over a larger area of ​​the water, increasing the range of cyanobacteria control achieved by the ultrasonic generator within the water. The vibration of ultrasound can cause the formation and rupture of tiny bubbles in the water, generating small water flows and impact forces. These forces can potentially cause mechanical damage to algal cells, thereby reducing or eliminating cyanobacteria growth.

[0008] Preferably, the first drive mechanism includes a first rotating shaft, a first motor, and a first transmission assembly. The first rotating shaft is vertically arranged and rotatably connected to the housing. A first end of the first rotating shaft is located inside the housing, and a second end of the first rotating shaft extends outside the housing and is fixedly connected to a drive ring. The output end of the first motor is connected to the first rotating shaft via the first transmission assembly. In use, the first motor drives the first rotating shaft to rotate via the first transmission assembly, thereby driving the drive ring to rotate.

[0009] Preferably, the first transmission component is a reduction gear set. Since the first transmission component is a reduction gear set, the first motor can drive the drive ring to rotate with less power, which can reduce the power requirement of the first motor.

[0010] Preferably, the first transmission assembly includes: a first mounting base, a second rotating shaft, a third rotating shaft, a first bevel gear, a second bevel gear, a first reduction gear, a second reduction gear, a first transmission gear, and a second transmission gear. The first mounting base is fixedly connected inside the chassis. The second and third rotating shafts are both rotatably mounted on the first mounting base. The first bevel gear is fixedly connected to the first end of the first rotating shaft. The second bevel gear and the first reduction gear are both fixedly connected to the second rotating shaft. The second reduction gear and the first transmission gear are both fixedly connected to the third rotating shaft. The second transmission gear is fixedly connected to the output end of the first motor. The diameter of the first reduction gear is larger than the diameter of the first transmission gear, and the diameter of the second reduction gear is larger than the diameter of the second transmission gear. The second bevel gear meshes with the first bevel gear, the first reduction gear meshes with the first transmission gear, and the second reduction gear meshes with the second transmission gear. Because the diameter of the first reduction gear is larger than the diameter of the first transmission gear, and the diameter of the second reduction gear is larger than the diameter of the second transmission gear, a two-stage reduction is formed through the two sets of gears, further reducing the power requirement of the first motor.

[0011] Preferably, the first mounting base is detachably connected to the chassis.

[0012] Preferably, a second mounting base is also included. The second mounting base is detachably connected inside the chassis and is located between the first mounting base and the top of the chassis. The first end of the first rotating shaft passes through the second mounting base, and the first rotating shaft is rotatably connected to the second mounting base. The second mounting base increases the constraint on the first rotating shaft, improving its stability.

[0013] Preferably, the second drive mechanism includes a second motor, a fourth rotating shaft, and a second transmission assembly. The second motor is fixedly connected to the first mounting base. The fourth rotating shaft is rotatably connected to the chassis. The first end of the fourth rotating shaft is located inside the chassis, and the second end of the fourth rotating shaft extends outside the chassis. The output end of the second motor is connected to the first end of the fourth rotating shaft via the second transmission assembly. The propeller is fixedly connected to the second end of the fourth rotating shaft.

[0014] Preferably, a solar panel is provided on the upper side of the floating plate. The solar panel can conveniently provide power to the first motor and the second motor.

[0015] Preferably, the chassis includes a housing and a cover. The housing has a mounting opening at its bottom, and the cover is detachably connected to the housing, capable of closing the mounting opening. The mounting opening facilitates the installation of internal components.

[0016] Preferably, the float plate is provided in three parts, and the float plates are evenly distributed along the circumference of the chassis. Attached image description:

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-6 The present invention will be further described in detail below with reference to specific embodiments.

[0026] Please see Figure 1-6This embodiment provides a device for controlling cyanobacterial blooms, including a housing 1. Several floating plates 2 are fixedly connected to the upper part of the housing 1, arranged horizontally. One end of each floating plate 2 is fixedly connected to the side of the housing 1, while the other end is away from the housing 1. A propeller 3 is rotatably mounted on the lower part of the housing 1, with its axis oriented horizontally. A drive ring 4 is rotatably mounted on the top of the housing 1, with its axis oriented vertically. The distance from the end of the floating plate 2 away from the housing 1 to the housing 1 is less than the radius of the drive ring 4. A first drive mechanism and a second drive mechanism are provided inside the housing 1. The first drive mechanism drives the drive ring 4 to rotate, and the second drive mechanism drives the propeller 3 to rotate. An ultrasonic generator 5 is provided on the housing 1. The ultrasonic generator 5 can be located outside or inside the housing 1; in this embodiment, it is preferred to locate the ultrasonic generator 5 inside the housing 1.

[0027] By adopting the above scheme, during use, the second drive mechanism drives the propeller 3 to rotate, thereby moving the housing 1 within the water area. This changes the planar position of the ultrasonic generator 5 within the water area, thus increasing the range of cyanobacteria control achieved by the ultrasonic generator 5. Since the first drive mechanism can drive the drive ring 4 to rotate, and the distance from the end of the float 2 away from the housing 1 to the housing 1 is less than the radius of the drive ring 4, when the entire device moves to the boundary of the water area, the drive ring 4 contacts the boundary. The reaction force generated after the drive ring 4 contacts the boundary drives the housing 1 to rotate, thereby changing the propulsion direction of the propeller 3, and consequently changing the movement direction of the entire device, allowing it to continue moving forward within the water area along the changed direction. Because the propulsion direction of the propeller 3 can be changed, the ultrasonic generator 5 can move within a larger area of ​​the water area, increasing the range of cyanobacteria control achieved by the ultrasonic generator 5 within the water area.
