[0024] like Figure 3 As shown, in this embodiment, the first sealed chamber assembly 300 includes a first main chamber 310, a first rear end cover 320, a first front end cover 330, and a first front end shell assembly 340. The first main chamber 310 is fitted inside the first bracket 200.

The first front end shell assembly 340 is fixed to the front end of the first front end cover 330. The interior of the first front end shell assembly 340 is an annular sealed space.
[0025] like Figure 4 As shown, the second sealed chamber assembly 700 includes a second main chamber 710, a second rear end cover 720, a second front end cover 730, and a second front end housing assembly 740.

The second front end housing assembly 740 is fixed to the front end of the second front end cover 730. The interior of the second front end housing assembly 740 is an annular sealed space.
[0026] Specifically, the first wireless optoelectronic integrated component 400 includes a first lens component 410, a first LED module 420, a first laser module 430, a first communication circuit 440, a first wireless charging module 450, and a first charging circuit 460. The first lens component 410 is mounted on the first front cover 330. The first LED module 420 and the first laser module 430 are located behind the first lens component 410. The first communication circuit 440 and the first charging circuit 460 are located inside the first main body 310. The first wireless charging module 450 is located in the annular sealed space of the first front housing component 340. The first LED module 420 and the first laser module 430 are electrically connected to the first communication circuit 440, and the first wireless charging module 450 and the first charging circuit 460 are electrically connected.
[0027] Specifically, the second wireless optoelectronic integrated component 800 includes a second lens assembly 810, a second LED module 820, a second laser module 830, a second communication circuit 840, a second wireless charging module 850, and a second charging circuit 860. The second lens assembly 810 is mounted on the second front end cover 730. The second LED module 820 and the second laser module 830 are located behind the second lens assembly 810. The second communication circuit 840 and the second charging circuit 860 are located inside the second main body 710. The second wireless charging module 850 is located in the annular sealed space of the second front end housing assembly 740. The second LED module 820 and the second laser module 830 are electrically connected to the second communication circuit 840, and the second wireless charging module 850 is electrically connected to the second charging circuit 860.
[0028] The first LED module 420 and the second LED module 820 of the present invention are respectively disposed after the first lens assembly 410 and the second lens assembly 810. There is a sealing structure between the first lens assembly 410 and the first front end cover 330, and between the second lens assembly 810 and the second front end cover 730. This not only allows the first LED module 420 and the second LED module 820 to work normally underwater, but also reduces light loss.
[0029] In this embodiment, the camera component 900 of the photoelectric receiving component uses the LED light source of the photoelectric emitting component as a light vision guidance target. After receiving the LED light signal, it feeds it back to the underwater unmanned vehicle, thereby guiding the underwater unmanned vehicle to dock with the docking station. Simultaneously, the first LED module 420 can wirelessly communicate with the second LED module 820, enabling long-distance, low-speed data transmission between the underwater unmanned vehicle and the base station during the recovery process. Furthermore, the camera component 900 can also communicate with the underwater unmanned vehicle for underwater image acquisition, providing visual data for marine research.
[0030] In this embodiment, the first laser module 430 and the second laser module 830 are respectively disposed after the first lens assembly 410 and the second lens assembly 810. A sealing structure 730 exists between the first lens assembly 410 and the first front end cover 330, and between the second lens assembly 810 and the second front end cover. This not only ensures the normal operation of the laser modules underwater but also reduces light loss. The first laser module 430 and the second laser module 830 are bidirectional data transmission modules, enabling non-contact, high-speed data transmission between the underwater unmanned vehicle and the docking station after docking.
[0031] The first wireless charging module 450 and the second wireless charging module 850 are respectively disposed in the annular sealed space of the first front-end housing assembly 340 and the second front-end housing assembly 740. Due to the annular structure design of the first front-end housing assembly 340 and the second front-end housing assembly 740, the light window range of the first LED module 420, the second LED module 820, the first laser module 430, and the second laser module 830 is avoided, so that the underwater unmanned vehicle can perform high-speed data transmission while performing non-contact charging, realizing non-contact signal and power transmission between the underwater unmanned vehicle and the docking station.
[0032] The first LED module 420 and the second LED module 820 of this invention can adopt the HCCLS-MOD03 series developed by Shenzhen Huachuang Xinguang Technology Co., Ltd., the camera component 900 can adopt the FPCTE-CT3022 high-definition underwater camera developed by Fuguang Precision Instruments (China) Co., Ltd., the first laser module 430, the second laser module 830, the first communication circuit 440 and the second communication circuit 840 can adopt the LC50CCA-50 / 40WD series developed by Wuhan Liubo Optoelectronic Technology Co., Ltd., and the first wireless charging module 450, the second wireless charging module 850, the first charging circuit 460 and the second charging circuit 860 can adopt the waterproof 1200W-48V-20A wireless charging series developed by Qingdao Luyu Energy Technology Co., Ltd.
[0033] The underwater wireless optoelectronic integrated signal and power transmission device of the present invention avoids interference between the wireless communication module (LED) and the wireless charging module by placing the wireless communication module (LED) and the laser module at the center of the sealed chamber, and the wireless charging module at the outer periphery of the sealed chamber, thus achieving simultaneous wireless signal and power transmission. Furthermore, by placing the wireless charging module within the annular housing at the front end of the wireless communication module, the wireless charging module avoids the light window area, preventing an increase in the radial dimension of the structure and improving the compactness and space utilization of the structure.
[0034] Additionally, the first front-end housing assembly 340 includes a first clamping ring 341 and a first front-end housing 342. The first clamping ring 341 is fixed to the front-end surface of the first front-end cover 330, and the first front-end housing 342 is fixed to the first clamping ring 341, forming an annular sealed space with the first clamping ring 341. The second front-end housing assembly 740 includes a second clamping ring 741 and a second front-end housing 742. The second clamping ring 741 is fixed to the front-end surface of the second front-end cover 730, and the second front-end housing 742 is fixed to the second clamping ring 741, forming an annular sealed space with the second clamping ring 741.
[0035] The first front-end housing assembly 340 and the second front-end housing assembly 740 of the present invention, through the structural design of the clamping ring and the housing, make the front-end housing assembly present a ring structure, avoiding the light window range of the LED module and the laser module, so that the underwater unmanned vehicle can perform high-speed data transmission while performing non-contact charging, thereby realizing non-contact signal and energy transmission between the underwater unmanned vehicle and the docking station.
[0036] like Figure 5 and Figure 6 As shown, in this embodiment, the first sealed chamber assembly 300 further includes a first lens cleaning mechanism 350, which includes four first servo motors 351 and four first brush strips 352, evenly distributed circumferentially on the first front end cover 330. One end of each brush strip 352 is fixed to the servo disc of the first servo motor 351. The second sealed chamber assembly 700 further includes a second lens cleaning mechanism 750, which includes four second servo motors 751 and four second brush strips 752, evenly distributed circumferentially on the second front end cover 730.

[0037] The first lens cleaning mechanism 350 and the second lens cleaning mechanism 750 of the present invention are respectively provided with multiple servo motors and corresponding brush strips for cleaning the surfaces of the first lens assembly 410 and the second lens assembly 810. Since the underwater unmanned vehicle needs to stay underwater for a long time, it is necessary to clean the lens assembly when necessary to prevent marine microorganisms and other foreign matter from affecting the light transmission effect of the lens assembly.
[0038] like Figure 7 and Figure 8 As shown, in this embodiment, the first sealed chamber assembly 300 further includes a first shielding assembly 360, which includes a first metal shielding plate 361 and a first shielding spring 362. The first metal shielding plate 361 is disposed inside the first main chamber 310, and the first shielding spring 362 is disposed inside the first main chamber 310 and sleeved on the outer periphery of the first shielding spring 362. The first metal shielding plate 361 and the first shielding spring 362 divide the first main chamber 310 into two compartments, and the first communication circuit 440 and the first charging circuit 460 are respectively disposed in the two compartments. The second sealed chamber assembly 700 also includes a second shielding assembly 760, which includes a second metal shielding plate 761 and a second shielding spring 762. The second metal shielding plate 761 is disposed inside the second main chamber 710, and the second shielding spring 762 is disposed inside the second main chamber 710 and sleeved on the outer periphery of the second shielding spring 762. The second metal shielding plate 761 and the second shielding spring 762 divide the second main chamber 710 into two compartments, and the second communication circuit 840 and the second charging circuit 860 are respectively disposed in the two compartments.
[0039] The first shielding component 360 and the second shielding component 760 of the present invention divide the first main body 310 and the second main body 710 into two compartments, and the two compartments are respectively equipped with communication circuits and charging circuits; by separating the high-voltage line from the data transmission line and performing electromagnetic shielding, electromagnetic interference can be effectively reduced and signal quality improved.
[0040] like Figure 2 and Figure 3 As shown, the first wireless optoelectronic integrated component 400 further includes a first connector component 470, which is fixed to the rear end face of the first rear end cover 320. The second wireless optoelectronic integrated component 800 further includes a second connector component 870, which is fixed to the rear end face of the second rear end cover 720.
[0041] The first connector assembly 470 and the second connector assembly 870 of the present invention are both watertight connector assemblies, which are respectively used as interfaces for data and energy transmission between the optoelectronic transmitting assembly and the docking station, and as interfaces for data and energy transmission between the optoelectronic receiving assembly and the underwater unmanned vehicle.
[0042] Working principle of the invention: The optoelectronic transmitter is mounted on the underwater docking station, and the optoelectronic receiver is mounted on the underwater unmanned vehicle (UAV). When the UAV returns to the docking station after completing its mission, the visual guidance equipment of the optoelectronic transmitter and receiver is activated to guide the UAV to dock with the docking station, while simultaneously transmitting data over a long distance at low speed. After docking, the docking station holds the UAV securely and deactivates the visual guidance equipment. Then, the wireless charging and laser communication equipment are activated to wirelessly charge the UAV and transmit data over a short distance at high speed.
