Description

Technical Field

[0001] This utility model relates to the field of acoustic Doppler current profiler technology, and in particular to a transducer surface cleaning mechanism for an ADCP. Background Technology

[0002] An acoustic Doppler current profiler (ADCP) is a device that uses acoustic principles to measure the velocity of water flow. It operates based on the Doppler effect, calculating the speed and direction of the water flow by emitting sound waves and receiving the sound waves reflected back by particles in the water.

[0003] Existing acoustic Doppler current profilers are equipped with one or more transducers, which are the core components of the acoustic Doppler current profiler.

[0004] Because acoustic Doppler current profilers are immersed in water (fresh or seawater) for a long time, sediment, dirt, or some microorganisms (such as algae) will accumulate on their surface. This will cause the transducer surface on the ADCP to be blocked, preventing it from working properly. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a transducer surface cleaning mechanism for ADCP.

[0006] The purpose of this utility model is achieved through the following technical solution: a transducer surface cleaning mechanism for an ADCP, including a transducer and a cleaning brush swinging device, wherein a cleaning brush is connected to the cleaning brush swinging device and the cleaning brush is in contact with the surface of the transducer; a hydrodynamic pressure applying component is provided on the cleaning brush; when the cleaning brush swings, the hydrodynamic pressure applying component applies pressure to the cleaning brush in the direction of the transducer.

[0007] Preferably, the cleaning brush oscillation device is an oscillation motor.

[0008] Preferably, the device also includes a base, and the transducer and cleaning brush oscillation device are all mounted on the base.

[0009] Preferably, the cleaning brush includes a frame, one end of which is connected to a cleaning brush swinging device, and a flexible brush strip is provided on the side of the frame facing the transducer.

[0010] Preferably, the flexible brush strip is made of rubber.

[0011] Preferably, the material of the skeleton is nylon.

[0012] Preferably, the hydrodynamic pressure application component is strip-shaped and is arranged along the axial direction of the cleaning brush. Both ends of the hydrodynamic pressure application component are connected to the skeleton on the cleaning brush through connecting parts. The side of the hydrodynamic pressure application component away from the transducer is a flat surface, and the side of the hydrodynamic pressure application component close to the transducer is an arc surface, which bulges towards the transducer.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, the cleaning brush is driven to swing by a cleaning brush swinging device, and the surface of the transducer is cleaned by the swinging of the cleaning brush; through the periodic automated cleaning process of the cleaning brush, the mud and dirt attached to the surface of the transducer can be effectively removed, thereby reducing the data deviation caused by surface contamination, and thus ensuring the accuracy and reliability of the measurement results.

[0015] 2. The cleaning brush swinging device can drive the cleaning brush to swing automatically, thereby realizing the automatic cleaning function and saving the trouble of manual cleaning.

[0016] 3. In this utility model, when the cleaning brush swings, the hydrodynamic pressure application component applies pressure to the cleaning brush in the direction of the transducer, which allows the cleaning brush to adhere closely to the surface of the transducer, thereby improving the cleaning effect on the transducer surface.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] like Figures 1 to 3As shown, an ADCP transducer surface cleaning mechanism includes a transducer 2, a cleaning brush swinging device 3, a cleaning brush 4 connected to the cleaning brush swinging device 3, and the cleaning brush 4 in contact with the surface of the transducer 2; a hydrodynamic pressure applying component 5 is provided on the cleaning brush 4; when the cleaning brush 4 swings, the hydrodynamic pressure applying component 5 applies pressure to the cleaning brush 4 in the direction of the transducer 2.

[0023] In this invention, the cleaning brush 4 is driven to swing by the cleaning brush swinging device 3, and the surface of the transducer 2 is cleaned by the swinging of the cleaning brush 4. The periodic automated cleaning process of the cleaning brush 4 effectively removes mud, sand, and dirt adhering to the surface of the transducer 2, thereby reducing data deviations caused by surface contamination and ensuring the accuracy and reliability of measurement results. The cleaning brush swinging device 3 drives the cleaning brush 4 to swing automatically, thus achieving an automatic cleaning function and eliminating the hassle of manual cleaning. In this invention, when the cleaning brush 4 swings, the hydrodynamic pressure applying component 5 applies pressure to the cleaning brush 4 in the direction of the transducer 2, which allows the cleaning brush 4 to adhere closely to the surface of the transducer 2, thereby improving the cleaning effect on the surface of the transducer 2.

[0024] In this embodiment, the cleaning brush oscillating device 3 is an oscillating motor. One end of the cleaning brush 4 is connected to the oscillating motor, which drives the cleaning brush 4 to oscillate back and forth.

[0025] This utility model also includes a base 1, a transducer 2 and a cleaning brush swing device 3, all of which are mounted on the base 1.

[0026] The cleaning brush 4 includes a frame 4a, one end of which is connected to the cleaning brush swing device 3. A flexible brush strip 4b is provided on the side of the frame 4a facing the transducer 2.

[0027] In this embodiment, the flexible brush strip 4b is made of rubber, and the skeleton 4a is made of nylon.

[0028] Furthermore, the hydrodynamic pressure application component 5 is strip-shaped and is arranged along the axial direction of the cleaning brush 4. Both ends of the hydrodynamic pressure application component 5 are connected to the skeleton 4a on the cleaning brush 4 through the connecting part 6. The side of the hydrodynamic pressure application component 5 away from the transducer 2 is a flat surface, and the side of the hydrodynamic pressure application component 5 close to the transducer 2 is an arc surface, which protrudes in the direction of the transducer 2.

[0029] The hydrodynamic pressure application component 5 has an inverted airfoil cross-section. When the cleaning brush 4 swings, water flows through the hydrodynamic pressure application component 5. Since the side of the hydrodynamic pressure application component away from the transducer 2 is a flat surface, while the side of the hydrodynamic pressure application component 5 near the transducer 2 is an arc surface, the water velocity on the arc surface side is greater than that on the other side when the water flows through the hydrodynamic pressure application component 5. According to Bernoulli's principle, the greater the fluid velocity, the lower the pressure. The velocity difference of the liquid on both sides of the hydrodynamic pressure application component 5 will generate a pressure difference. The direction of this pressure difference is towards the transducer 2. This pressure difference applies pressure to the cleaning brush 4 in the direction of the transducer 2, thereby making the cleaning brush 4 adhere tightly to the surface of the transducer 2 and improving the cleaning effect.

[0030] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
