The scraper ring is sleeved on the outer surface of the first and second protective covers.

[0009] The underwater camera and the dual-head motor are both connected to wires on their outer surfaces. The other end of the wires extends outward through the first protective cover and the second adapter tube. The other end of the wires is equipped with an adapter.

[0023] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Example 1

[0025] As attached Figure 1-5The intelligent device for underwater image acquisition shown includes a float 1, a control computer 2 located in the middle of the upper surface of the float 1, a first adapter tube 4 located in the middle of the lower surface of the float 1, an extension rod 5 installed at the other end of the first adapter tube 4, a second adapter tube 10 installed at the other end of the extension rod 5, a hemispherical first protective cover 8 located at the other end of the second adapter tube 10, and a hemispherical second protective cover 9 installed on the lower surface of the first protective cover 8.

[0026] A movable frame 11 is movably mounted on the inner top surface of the first protective cover 8 via a bearing. The other end of the movable frame 11 is provided with a fixing ring. An underwater camera 12 is mounted on the inner surface of the movable frame 11 via the fixing ring. A partition 15 is provided above the inner bottom surface of the second protective cover 9. The outer surface of the partition 15 is connected to the inner surface of the second protective cover 9. A dual-head motor 16 is provided in the middle of the upper surface of the partition 15. One output end of the dual-head motor 16 is inserted into the fixing ring on the movable frame 11, and the other output end of the dual-head motor 16 extends outward through the partition 15.

[0027] The second protective cover 9 has an opening in the middle of its lower surface. A sealing disc 18 is installed on the inner surface of the second protective cover 9 through the opening. The middle of the upper surface of the sealing disc 18 is connected to the other output end of the dual-head motor 16. A scraper ring 19 is provided on the lower surface of the sealing disc 18. The scraper ring 19 is sleeved on the outer surface of the first protective cover 8 and the second protective cover 9.

[0028] The outer surfaces of the underwater camera 12 and the dual-head motor 16 are connected to wires 13. The other end of the wires 13 extends outward through the first protective cover 8 and the second adapter tube 10. The other end of the wires 13 is provided with an adapter 14. The other end of the wires 13 passes through the extension rod 5 and the first adapter tube 4 and the float 1 respectively, and is connected to the control computer 2 through the adapter 14.

[0029] During operation, the first protective cover 8 and the second protective cover 9 can be assembled and installed. Since the first protective cover 8 and the second protective cover 9 are made of transparent organic glass, the underwater camera 12 can be located inside the first protective cover 8 and the second protective cover 9 to collect underwater images. The first protective cover 8 and the second protective cover 9 can protect the underwater camera 12 from damage underwater.

[0030] After the first protective cover 8 and the second protective cover 9 are assembled, the extension rod 5 can be assembled according to the required underwater image acquisition depth. During the assembly process, the wire 13, which connects to the underwater camera 12 and the dual-head motor 16, is passed through the extension rod 5. When the extension rod 5 is assembled to the length equal to the required underwater image acquisition depth, the wire 13 can be passed out of the extension rod 5, and its adapter 14 is inserted and connected to the first adapter tube 4, the float 1, and the control computer 2. At this time, the control computer 2 can be electrically connected to the underwater camera 12 and the dual-head motor 16 through the wire 13, thereby controlling the operation of the underwater camera 12 and the dual-head motor 16 through the control computer 2. After the wire 13 is connected to the control computer 2, the extension rod 5 can be assembled and connected to the first adapter tube 4. At this time, the complete assembly of the image acquisition device is completed.

[0031] Once the image acquisition equipment is assembled, it can be deployed to the water area to be acquired. The float 1 will then float on the surface, allowing personnel to control the equipment within the water. The image reading device can then be wirelessly connected to the signal module in the control computer 2. In this case, the image reading device, in conjunction with the control computer 2, can control the underwater camera 12 and the dual-head motor 16. The control module in the control computer 2 can then activate the underwater camera 12, which monitors underwater images. The image data detected by the underwater camera 12 is transmitted via wire 13 to the data receiving module in the control computer 2. Upon receiving the image data, the data receiving module in the control computer 2 wirelessly transmits it to the image reading device via the signal module, thus completing the underwater image acquisition.

[0032] When underwater images need to be acquired from multiple angles, the control module in the control computer 2 can control the start of the dual-head motor 16. When the dual-head motor 16 is started, the scraper ring 19 connected to one of its output ends will rotate on the outer surface of the spherical shield formed by the first protective cover 8 and the second protective cover 9 as the dual-head motor 16 operates. At this time, the rotation of the scraper ring 19 can be used to scrape and clean the surface of the first protective cover 8 and the second protective cover 9, thereby removing any underwater impurities that may be adhering to the outer surface of the first protective cover 8 and the second protective cover 9. This helps to maintain the cleanliness of the outer surface of the first protective cover 8 and the second protective cover 9, thus facilitating the underwater camera 12 to pass through the shield from inside. Image acquisition is performed while the output end of the other end of the dual-head motor 16 is locked to the movable frame 11. In this case, the movable frame 11 will rotate synchronously with the operation of the dual-head motor 16. When the movable frame 11 is rotating, the underwater camera 12 locked on its inner surface will rotate synchronously, thereby achieving 360-degree acquisition of underwater images. During the rotation, the underwater camera 12 does not need to make large movements, which helps to save the energy consumption of the underwater camera 12. At the same time, the dual-head motor 16 rotates one revolution clockwise and one revolution counterclockwise. This rotation method helps to avoid the phenomenon of the wire 13 connected to the underwater camera 12 getting tangled, thereby achieving the effect of protecting the wire 13.

[0033] Refer to the instruction manual appendix Figure 1-5 As shown, the upper surface of the float 1 is provided with a hemispherical isolation cover 3.

[0034] The control computer 2 on the floating plate 1 can be isolated and protected by the isolation cover 3.

[0035] One end of the outer surface of the extension rod 5 is provided with a protruding connecting rod 6, and the other end of the outer surface of the extension rod 5 is provided with a concave connecting port 7. Both the outer surface of the connecting rod 6 and the inner surface of the connecting port 7 are provided with threads, and the outer surface of the extension rod 5 is provided with scale lines.

[0036] By inserting the connecting rod 6 into the connecting port 7, multiple extension rods 5 can be connected in series. At the same time, the threaded connection method can improve the sealing effect between the extension rods 5. The depth of the extension rod 5 underwater can be seen through the scale lines on the outer surface of the extension rod 5.

[0037] The first protective shield 8, the second protective shield 9, and the isolation shield 3 are all made of transparent plexiglass.

[0038] The first protective cover 8, the second protective cover 9, and the isolation cover 3 are made of transparent plexiglass. The first protective cover 8 and the second protective cover 9 can protect the underwater camera 12 while avoiding obstruction of its image acquisition.

[0039] A fixing frame 17 is fitted on the outer surface of the dual-head motor 16, and the fixing frame 17 is connected to the upper surface of the partition 15.

[0040] The dual-head motor 16 can be locked and fixed in place by the mounting bracket 17.

[0041] Both the scraper ring 19 and the sealing disc 18 are made of rubber. A limiting ring 20 is provided in the middle of the upper surface of the scraper ring 19. The limiting ring 20 is sleeved on the lower part of the outer surface of the second adapter cylinder 10.

[0042] The scraper ring 19 and the sealing disc 18 are made of rubber. The scraper ring 19 can better scrape away underwater impurities that may be attached to the surface of the first protective cover 8 and the second protective cover 9 by means of the friction of the rubber material itself. At the same time, the sealing disc 18 made of rubber can improve the sealing effect to prevent water from entering the second protective cover 9. The limiting ring 20 can make the scraper ring 19 fit more closely to the outer surface of the first protective cover 8 and the second protective cover 9, thereby providing a better impurity removal effect.

[0043] The underwater camera 12 and the dual-head motor 16 are both electrically connected to the control computer 2 via wires 13. The wires 13 contain data transmission lines and control lines.

[0044] The control computer 2 can control the operation of the underwater camera 12 and the dual-head motor 16 through the control circuit in the wire 13. At the same time, the control computer 2 can receive the image acquisition data of the underwater camera 12 through the data transmission line in the wire 13.

[0045] In summary, this intelligent device can avoid damage to the device in complex underwater environments without affecting image acquisition. Secondly, it helps save underwater energy consumption and avoids the phenomenon that image acquisition is affected by underwater impurities that are difficult to clean.
