Description

Technical Field

[0001] This utility model relates to the field of wave sensor technology, specifically a buoy wave sensor. Background Technology

[0002] The wave sensor measures waves using the principle of gravity acceleration. It is equipped with a nine-axis MEMS-IMU inertial measurement unit and uses strapdown inertial navigation technology to calculate the acceleration and attitude of the carrier in the geographic coordinate system (East-North-Sky coordinate system). By eliminating the accumulated errors generated in solving differential equations, acceleration integration, and velocity integration, it can quickly calculate wave height, wave period, wave direction, one-dimensional energy density spectrum, two-dimensional direction spectrum, and spectral characteristic parameters of wind, waves, and swells. This sensor can be applied to various types of buoys and other observation platforms.

[0003] Current wave sensors transmit data via data cables, so they typically have a data cable socket for connection with a plug at the cable end. However, since wave sensors are placed on the sea surface, when waves break up due to wind, they create numerous bubbles (approximately 10–500 micrometers in diameter). When these bubbles rise to the surface and burst, they generate micron-sized saltwater droplets (called marine aerosols). These droplets can easily corrode the wave sensor's connectors, affecting its lifespan and potentially causing data transmission interruptions. Utility Model Content

[0026] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-3 This utility model provides a technical solution:

[0028] A buoy wave sensor includes a sensor body 1, a sheath 2 on the side of the sensor body 1, a first data line 21 connected to the sensor body 1 passing through the sheath 2, and a socket 22 at the end of the first data line 21 being plugged into and connected to a plug 41 of a second data line 4, thereby realizing data transmission of the sensor body 1.

[0029] In this invention, a conical head 3 is fixedly connected to one end of the sheath 2, and a first conical surface 31 is provided on the outer surface of the conical head 3. Further, as shown in the figure, the conical head 3 is generally frustum-shaped, and the diameter of its large-diameter end is equal to the diameter of the sheath 2. The conical head 3 is inserted into the groove 51 at one end of the sleeve 5, and the inner surface of the groove 51 is a second conical surface 52. A plurality of first sealing rings 6 are fixedly provided on the second conical surface 52. In this embodiment, the number of first sealing rings 6 is not less than two, preferably three or more, and the plurality of first sealing rings 6 are equidistantly arranged. As shown in the figure, along the direction in which the cross-sectional area of ​​the conical head 3 gradually decreases, the distance between the first conical surface 31 and the second conical surface 52 gradually increases.

[0030] The socket 22 of the first data cable 21 passes through the conical head 3 and is elastically connected to the plug 41 of the second data cable 4 in the groove 51. The sleeve 5 is sealed to the second data cable 4. For example, the material of the sleeve 5 can be the same as the outer sheath of the second data cable 4, and the two are integrally formed to achieve a sealed connection between the sleeve 5 and the second data cable 4. Other methods can also be used to achieve a sealed connection, such as using high-strength adhesive to achieve a seal. No specific limitation is made in this regard. The purpose of the sealed connection is to prevent marine aerosols containing salt from entering the interior of the groove 51 from the connection position between the sleeve 5 and the second data cable 4.

[0031] The first sealing ring 6 inside the sleeve 5 is pressed against the first conical surface 31 by an elastic component, from Figure 2 As can be seen from the diagram, this embodiment has seven first sealing rings 6, numbered from one to seven according to their direction of increasing distance from the sheath 2. Only the first and second first sealing rings 6 contact the first conical surface 31 through the elastic force of the elastic component; the remaining five first sealing rings 6 do not contact the first conical surface 31. In actual use, since the first sealing ring 6 is located on the outermost layer, it will directly contact the marine aerosol. Prolonged contact can easily lead to corrosion of the first sealing ring 6, resulting in poor sealing performance, allowing the marine aerosol to enter the first sealing ring 6. Between the first sealing ring 6 and the second first sealing ring 6, marine aerosol will begin to gradually corrode the second first sealing ring 6. However, due to the corrosion of the first first sealing ring 6, its inner diameter increases. Therefore, under the elastic force of the elastic component, the entire sleeve 5 will move to the left relative to the conical head 3, so that the third first sealing ring 6, which was not originally in contact with the first conical surface 31, will come into contact with the first conical surface 31. In this way, multi-level defense against marine aerosols can be achieved, preventing marine aerosols from entering the insertion position of the socket 22 and the plug 41, which can significantly reduce the probability of the socket 22 and the plug 41 being corroded and extend the maintenance cycle of the sensor body 1.

[0032] The other end of the sleeve 5 is fixedly connected to a second sealing ring 7. The inner circumferential surface of the second sealing ring 7 is sealed on the circumferential surface of the sheath 2. The second sealing ring 7 can serve as a first-level protection system to prevent marine aerosol penetration.

[0033] A spring 10 connects the socket 22 and the conical head 3, and the first data line 21 passes through the spring 10. A storage groove 32 is provided at one end of the conical head 3, and the spring 10 is located inside the storage groove 32. The spring 10 supports the socket 22, allowing the plug 41 to be smoothly connected to the socket 22, ensuring stable data transmission. Furthermore, since the relative position of the sleeve 5 and the conical head 3 changes, that is, the sleeve 5 moves under the elastic force of the elastic component, the spring 10 can also dynamically compensate for the amount of movement of the sleeve 5.

[0034] The second conical surface 52 has several annular grooves 53, and the outer periphery of the first sealing ring 6 is fixedly disposed inside the annular grooves 53.

[0035] The elastic component includes a spring plate 8, which is made of a corrosion-resistant material. One end of the spring plate 8 is fixedly connected to the sleeve 5, and the other end of the spring plate 8 is fixedly connected to the mounting carrier (e.g., a buoy) of the sensor body 1. The elastic force generated by the spring plate 8 when it is compressed is greater than the maximum elastic force that the spring 10 can generate.

[0036] The other end of the spring plate 8 is fixedly connected to a support cylinder 9, and one end of the support cylinder 9 is fixedly connected to a mounting base 91. The mounting base 91 is fixedly connected to the mounting carrier by fasteners. Furthermore, a gasket 92 is provided between the mounting base 91 and the mounting carrier. The gasket 92 can be used to increase the deformation of the spring plate 8. A through groove 93 is provided on the side wall of the support cylinder 9, and the second data line 4 is led out from the inside of the support cylinder 9 through the through groove 93.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
