Description

Technical Field

[0001] This utility model relates to the field of sensors, and in particular to a waterproof and dustproof underwater operation sensor. Background Technology

[0002] Underwater acoustic sensors are devices that utilize the propagation characteristics of sound waves in water to acquire information. Sound waves can travel long distances in water with minimal signal attenuation, which lays the foundation for the effectiveness of underwater acoustic sensors. Common types include multi-beam sonar, which emits multiple beams of sound waves and uses the echoes to accurately map underwater topography; side-scan sonar, which scans with fan-shaped sound waves to acquire two-dimensional acoustic images of underwater objects, often used to detect targets such as shipwrecks; and Doppler current profilers, which measure the velocity and direction of water currents at different depths. These acoustic sensors are widely used in marine exploration, underwater engineering, and fisheries resource monitoring, helping to map the seabed, guide underwater robot operations, and assess the impact of water currents on marine facilities, making them key technologies for exploring and utilizing the underwater environment.

[0003] Underwater acoustic sensors suffer from several shortcomings in waterproofing and dustproofing. On one hand, the connection between the sensor chip wires and the housing is susceptible to water seepage due to design flaws, and dust can easily enter through this point even in surface environments. On the other hand, the lower housing of the sensor, which uses a threaded connection for easy maintenance or chip replacement, is prone to water seepage through the thread gaps when exposed to prolonged underwater conditions. Both of these factors can damage the internal electronic components of the sensor, significantly reducing its lifespan and reliability.

[0004] Therefore, a waterproof and dustproof underwater sensor is needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a waterproof and dustproof underwater operation sensor to solve the problem of poor waterproof and dustproof effect.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a waterproof and dustproof underwater operation sensor, including a central shell and an upper sealing shell installed on the upper end of the central shell, an acoustic wave sensing chip installed on the inner side of the central shell, and a lower sealing shell threaded on the lower end of the central shell.

[0007] A connecting post is fixedly installed at the lower end of the upper sealing shell. The outer side of the connecting post is threadedly connected to the upper inner side of the central shell. A support ring is threadedly installed on the inner side of the upper end of the central shell. A sealing ring is fixedly glued to the upper end of the support ring. The inner diameter of the sealing ring is matched with the outer diameter of the wire. The sealing ring is located on the lower side of the connecting post after installation, and the connecting post after installation squeezes the sealing ring.

[0008] Furthermore, the sealing ring is a component made of rubber material, and the inside of the sealing ring is hollow.

[0009] Furthermore, the upper end of the upper sealing shell is provided with sealing sheet one, sealing sheet two and sealing sheet three from top to bottom. The upper end of the upper sealing shell is provided with a hollow extension head. Sealing sheet one is located at the upper inlet of the extension head. The inner diameters of sealing sheet one, sealing sheet two and sealing sheet three are all smaller than the diameter of the wire.

[0010] Furthermore, a threaded groove is provided on the outer side of the central shell, and a threaded assembly is provided on the outer side of the threaded groove. The threaded assembly includes an upper washer and an upper bolt. The upper washer is fitted on the outer side of the central shell, and the upper bolt is threadedly matched with the threaded groove.

[0011] Furthermore, the thread assembly also includes a lower washer and a lower bolt. The lower washer is fitted on the outside of the central shell, and the lower bolt is threaded to match the thread groove.

[0012] Furthermore, the upper end of the lower sealing shell is threaded to the inner side of the central shell, a baffle is provided on the outer side of the lower sealing shell, and a lower sealing ring is installed on the upper end of the lower sealing shell located inside the baffle, the lower sealing ring extending out of the upper side of the baffle.

[0013] Furthermore, the upper end of the lower sealing shell is threadedly connected to the inner side of the central shell, and a baffle is provided on the outer side of the lower sealing shell. A lower sealing ring is installed on the upper end of the lower sealing shell located inside the baffle. The lower sealing ring extends out of the upper side of the baffle and is located on the outer side of the lower end of the central shell.

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] 1. During installation, connect the upper sealing shell and the central shell. As the connecting column thread moves downward, it compresses the sealing ring, causing the sealing ring to deform and fit tightly against the outside of the wire. The connection between the sensor chip wire and the shell is not easily affected by water seepage, and in a water environment, dust is not easily invaded from here, resulting in good waterproof and dustproof performance.

[0016] 2. When installing the sensor and the carrier equipment, fix the lower gasket and lower bolt in the locking position, tighten the upper gasket and upper bolt, and then install the lower sealing shell so that the lower sealing ring contacts the lower bolt. Then, they are squeezed to seal the connection between the lower sealing shell and the central shell. Moreover, the threaded assembly and the lower sealing ring can increase the amount of water entering the threaded gap between the lower sealing shell and the central shell, further improving the waterproof effect.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Combination Figures 1-2 A waterproof and dustproof underwater operation sensor includes a central shell 1 and an upper sealing shell 2 screwed onto the upper end of the central shell 1. An acoustic wave sensing chip 8 is installed inside the central shell 1, and a probe 81 is installed at the lower end of the acoustic wave sensing chip 8. A lower sealing shell 5 is threaded onto the lower end of the central shell 1. The acoustic wave sensing chip 8 emits sound waves through the probe 81, which pass through the lower sealing shell 5 and enter the water. The echo is then used to accurately map the underwater topography.

[0027] Combination Figures 3-4A connecting post 21 is fixedly installed at the lower end of the upper sealing shell 2. The outer side of the connecting post 21 is threadedly connected to the upper inner side of the center shell 1. A support ring 3 is threadedly installed on the upper inner side of the center shell 1. A sealing ring 4 is glued to the upper end of the support ring 3. The sealing ring 4 is made of rubber and is hollow inside. The inner diameter of the sealing ring 4 is adapted to the outer diameter of the wire. The sealing ring 4 is located below the connecting post 21 after installation and is squeezed at this time. After the wire passes through the center of the sealing ring 4, the upper sealing shell 2 is connected to the center shell 1 during installation. As the connecting post 21 moves downward, it squeezes the sealing ring 4, causing the sealing ring 4 to deform and fit tightly against the outer side of the wire. The connection between the sensor chip wire and the shell is not easily affected by water seepage, and dust is not easily invaded from this point in a water environment, resulting in good waterproof and dustproof performance.

[0028] Furthermore, to further improve the waterproof and dustproof effect, an extension head is provided at the upper end of the upper sealing shell 2. The inner side of the extension head is provided with sealing sheet 1 22, sealing sheet 23 and sealing sheet 3 24 from top to bottom. Sealing sheet 1 22 is located at the upper entrance of the extension head. The inner diameters of sealing sheet 1 22, sealing sheet 23 and sealing sheet 3 24 are all smaller than the diameter of the wire. The inner diameter of sealing sheet 1 22 is smaller than the inner diameter of sealing sheet 23 and the inner diameter of sealing sheet 3 24. Thus, after the wire passes through sealing sheet 1 22, sealing sheet 23 and sealing sheet 3 24, they can fit tightly with the wire to achieve a preliminary waterproof and dustproof effect.

[0029] Combination Figure 2 The outer side of the central shell 1 is provided with a threaded groove 11, and the outer side of the threaded groove 11 is provided with a threaded assembly 9. The threaded assembly 9 is used to install the entire sensor on a carrier device, such as a ship or a buoy.

[0030] Combination Figure 2 , Figure 3 as well as Figure 5 The threaded assembly 9 includes an upper washer 91 and an upper bolt 92. The upper washer 91 is fitted on the outside of the central shell 1, and the upper bolt 92 is threadedly matched with the threaded groove 11. The threaded assembly 9 also includes a lower washer 93 and a lower bolt 94. The lower washer 93 is fitted on the outside of the central shell 1, and the lower bolt 94 is threadedly matched with the threaded groove 11.

[0031] The upper end of the lower sealing shell 5 is threaded to the inner side of the central shell 1. A baffle 6 is provided on the outer side of the lower sealing shell 5. A lower sealing ring 7 is installed on the upper end of the lower sealing shell 5 located inside the baffle 6. The lower sealing ring 7 extends out of the upper side of the baffle 6 and is located on the outer side of the lower end of the central shell 1. When installing the sensor and the carrier equipment, the lower gasket 93 and the lower bolt 94 are locked in place. The upper gasket 91 and the upper bolt 92 are tightened. Then the lower sealing shell 5 is installed so that the lower sealing ring 7 contacts the lower bolt 94. Then it is squeezed to seal the connection between the lower sealing shell 5 and the central shell 1. Moreover, the threaded assembly 9 and the lower sealing ring 7 can increase the amount of water entering the threaded gap between the lower sealing shell 5 and the central shell 1 from the thread gap, further improving the waterproof effect.

[0032] The technical scope of this utility model 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 utility model, and all such modifications and variations should fall within the protection scope of this utility model.
