Description

Technical Field

[0001] This utility model relates to the field of unmanned surface vessel (USV) mapping instrument brackets, specifically an extended bracket for an USV mapping instrument. Background Technology

[0002] Marine surveying is the work of measuring and compiling nautical charts of ocean waters and seabed. With the development and application of electronic computers and computing technology, unmanned surface vessels (USVs) are widely used in marine surveying. When using USVs, an extension bracket needs to be installed on the unmanned vessel to adjust the position of the USV.

[0003] According to publicly available patent CN220287023U, an extension bracket for an unmanned surface vessel (USV)-borne surveying instrument is disclosed. This bracket facilitates adjustment of the USV-borne surveying instrument's orientation during fixed-point surveying, expanding the surveying area and reducing the device's limitations. It includes a base, a mounting platform, a lifting mechanism, and a lifting platform. The base is mounted on an external USV, the mounting platform is fixed to the top of the base, and the lifting mechanism is mounted on the mounting platform. The lifting mechanism moves the lifting platform up and down, with the USV-borne surveying instrument positioned above it. A rotating mechanism is also included, mounted on the lifting platform, with the USV-borne surveying instrument fixed to it. The rotating mechanism drives the USV-borne surveying instrument. However, traditional methods only allow for height and rotation adjustments of the USV-borne surveying instrument, not angle adjustments. This results in a limited surveying range and significant limitations in the device's use. Furthermore, the electric push rod and retraction rod are located on the outside, making them susceptible to water damage, accelerating corrosion, and even causing damage. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an extension bracket for an unmanned surface vessel (USV) mapping instrument. This solves the problem that the current system can only adjust the height and rotation of the USV mapping instrument, but cannot adjust the angle of the USV mapping instrument. As a result, the USV mapping instrument has a small mapping range, which leads to a large limitation in the use of the device. Furthermore, the electric push rod and the retraction rod are located on the outside, making them easy to be wetted by water, which accelerates the corrosion of the electric push rod and the retraction rod, and may even cause damage.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an extension bracket for an unmanned surface vessel (USV) mapping instrument, including a sphere, the sphere having a hollow structure, a rectangular adjustment hole opened at the center of the top of the sphere, a connecting shaft rotatably connecting the two sides of the center of the inner cavity of the sphere, a support rod installed at the center of the outer side of the connecting shaft, the support rod passing through a rectangular through hole and placed on the outer side of the sphere, a mounting base installed at the top of the support rod, and the USV mapping instrument body installed on the mounting base;

[0006] A first driven gear is installed on the outer side of the connecting shaft, and a first drive motor is installed on one side of the inner cavity of the sphere. A drive gear is installed on the drive end of the first drive motor, and the drive gear meshes with the first driven gear.

[0007] Preferably, a support column is provided at the center of the bottom end of the sphere, and a sleeve is slidably sleeved on the outer side of the bottom of the support column. An electric telescopic rod and a second drive motor are installed at the bottom of the inner cavity of the sleeve. An installation shaft is installed at the drive end of the electric telescopic rod. The installation shaft is rotatably connected to the bottom of the support column through a bearing. A second driven gear is installed on the outer side of the installation shaft. A gear post is installed at the drive end of the second drive motor. The gear post meshes with the second driven gear.

[0008] Preferably, a circular cover is installed on the outside of the support rod on the outer side of the sphere, the inner side of the circular cover is fitted to the outer side of the sphere, and the diameter of the circular cover is greater than the length of the rectangular adjustment hole.

[0009] Preferably, a first sealing gasket is installed on the outer side of the support column, and the first sealing gasket is elastic, with the outer side of the first sealing gasket fitting against the inner wall of the sleeve.

[0010] Preferably, a base plate is installed at the bottom of the sleeve, and a fixing bolt passes through the surface of the base plate.

[0011] Preferably, an inspection hole is provided at the center of the bottom end of the sphere, an inspection cover plate is provided in the inspection hole, a bolt passes through the inspection cover plate and is threaded to the surface of the sphere, a support column is installed at the center of the bottom end of the inspection cover plate, and a second sealing gasket is installed on the outside of the inspection cover plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention combines a sleeve, a support column, a first drive motor, a second drive motor, an electric telescopic rod, a driving gear, a first driven gear, a second driven gear, a gear post, a rectangular adjustment hole mounting shaft, and a support rod. The electric telescopic rod allows adjustment of the unmanned surface vessel (USV) mapping height. Because the second driven gear is always meshed with the gear post, activating the second drive motor rotates the sphere and the USV mapping body. Activating the first drive motor then adjusts the mapping angle of the USV mapping body, thereby increasing its mapping range. Furthermore, it prevents the electric telescopic rod, the first drive motor, and the second drive motor from getting wet when adjusting the mapping range, thus extending their service life.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: An extension bracket for an unmanned surface vessel-borne mapping instrument, see [link / reference] Figures 1 to 5The system includes a sphere 22, which is hollow. A rectangular adjustment hole 25 is provided at the center of the top of the sphere 22. A connecting shaft 27 is rotatably connected between the two sides of the center of the inner cavity of the sphere 22. A support rod 26 is installed at the center of the outer side of the connecting shaft 27. The support rod 26 passes through a rectangular through hole and is placed on the outer side of the sphere 22. A mounting base 23 is installed on the top of the support rod 26. An unmanned surface vessel mapping instrument body 3 is installed on the mounting base 23 (which integrates a multibeam echo sounder, a side-scan sonar, a single-beam echo sounder, a water quality sensor, an inertial navigation system, and GPS sensors to achieve high-precision acquisition and processing of water topography, water depth, water quality, and other data).

[0022] A first driven gear 42 is mounted on the outer side of the connecting shaft 27. A first drive motor 4 is mounted on one side of the inner cavity of the ball 22. A drive gear 41 is mounted on the drive end of the first drive motor 4. The drive gear 41 meshes with the first driven gear 42. A support column 21 is provided at the middle of the bottom end of the ball 22. A sleeve 2 is slidably sleeved on the outer side of the bottom of the support column 21. An electric telescopic rod 5 and a second drive motor 6 are mounted on the bottom end of the inner cavity of the sleeve 2. An installation shaft 52 is mounted on the drive end of the electric telescopic rod 5. The support column 21 is rotatably connected to the bottom of the support column 21 via a bearing. A second driven gear 51 is installed on the outer side of the mounting shaft 52. A gear column 61 is installed on the drive end of the second drive motor 6. The gear column 61 meshes with the second driven gear 51. A circular cover 24 is installed on the outside of the support rod 26 on the outer side of the ball 22. The inner side of the circular cover 24 fits against the outer side of the ball 22. The diameter of the circular cover 24 is larger than the length of the rectangular adjustment hole 25. A base plate 1 is installed at the bottom of the sleeve 2. A fixing bolt 11 passes through the surface of the base plate 1.

[0023] During operation, the mounting bolt 11 is screwed onto the surface of the unmanned surface vessel (USV) via a threaded connection, and the expansion bracket is fixed in conjunction with the base plate 1. When the mapping range of the USV mapping instrument body 3 needs to be adjusted, the support column 21 is moved by activating the electric telescopic rod 5, thereby adjusting the mapping height of the USV mapping instrument body 3. When adjusting the height of the USV mapping instrument body 3, since the second driven gear 51 and the gear column 61 are always meshed, the second drive motor 6 is activated to drive the gear column 61 to rotate, which in turn drives the support column 21 to rotate, thereby rotating the sphere 22 and the USV mapping instrument body 3. Then, the first drive motor 4 is activated to drive the drive gear 41 to rotate, which in turn drives the connecting gear 42 to rotate the connecting gear 22. The rotating shaft 27 and support rod 26 allow for adjustment of the surveying angle of the unmanned surface vessel (USV) surveyor body 3, thereby increasing its surveying range. When adjusting the surveying range of the USV surveyor body 3, the electric telescopic rod 5 and the second drive motor 6 are located inside the sleeve 2. Simultaneously, the circular cover 24 rotates with the angle adjustment of the USV surveyor body 3, always blocking the rectangular adjustment hole 25. This seals the first drive motor 4 within the sphere 22, preventing the electric telescopic rod 5, the first drive motor 4, and the second drive motor 6 from being exposed to water when adjusting the surveying range of the USV surveyor body 3, further extending their service life.

[0024] For details, see Figure 3 A first sealing gasket 28 is installed on the outer side of the support column 21, and the first sealing gasket 28 is elastic. The outer side of the first sealing gasket 28 is fitted to the inner wall of the sleeve 2. The first sealing gasket 28 increases the sealing performance of the connection between the support column 21 and the sleeve 2, and further prevents rainwater from entering the sleeve 2 through the gap between the support column 21 and the sleeve 2 and damaging the electric telescopic rod 5 and the second drive motor 6.

[0025] Further, see Figure 2 and Figure 5 The sphere 22 has an inspection hole 7 at the bottom center, and an inspection cover plate 71 is installed inside the inspection hole 7. A bolt 73 passes through the inspection cover plate 71 and is threaded to the surface of the sphere 22. The support column 21 is installed at the bottom center of the inspection cover plate 71. A second sealing gasket 72 is installed on the outside of the inspection cover plate 71. By tightening the bolt 73, the sphere 22 can be disassembled, which facilitates the maintenance of the first drive motor 4 inside the sphere 22. The second sealing gasket 72 is used to increase the sealing of the connection between the inspection cover plate 71 and the inspection hole 7, thereby improving the waterproof effect at the connection between the inspection cover plate 71 and the inspection hole 7.
