Description

Technical Field

[0001] This utility model relates to the field of underwater docking box technology, and more specifically to a self-powered underwater docking box. Background Technology

[0002] With the continuous development of marine resource development and marine environmental monitoring, underwater detection networks are being used more and more widely. As an important component of underwater detection networks, underwater junction boxes primarily undertake signal and data transmission functions, as well as power conversion and distribution functions. For example, a single-pole negative voltage powered underwater observation network junction box (publication number CN205986139U) has a simple structure, is easy to install, and can be applied to the power transmission system of long-distance, large-area seabed observation networks, providing continuous and stable power support for underwater equipment. Simultaneously, DC single-pole power supply reduces the number of cable cores and manufacturing cost of the submarine optical fiber composite cable used for transmission.

[0003] Existing underwater junction boxes present several challenges for long-distance transmission: 1. Signal transmission issues: Underwater sensors typically collect various types of electrical signals, which have limited transmission distances. Long-distance transmission often requires optical signals, necessitating photoelectric conversion modules to convert electrical signals into optical signals for remote transmission. At the receiving terminal, these modules convert the optical signals back into electrical signals. However, photoelectric conversion modules require a power supply to function properly. 2. Power supply issues: Underwater equipment is usually powered via cables. For long distances, terminal-based power supply not only requires long cables but also results in significant voltage drops due to the distance, leading to substantial costs in both cable materials and power loss.

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-powered underwater docking box. By placing a battery pack inside the docking box to continuously power the photoelectric conversion module, and setting a power supply interface on the docking box to charge the battery pack, the docking box can be used repeatedly without external power supply, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-powered underwater docking box, comprising a pressure-bearing shell, an installation plate inside the pressure-bearing shell, a photoelectric conversion module fixedly mounted on the top of the installation plate, a battery pack fixedly mounted on the bottom of the installation plate, a front sealing cover and a rear sealing cover respectively mounted on the front and rear ends of the pressure-bearing shell, the installation plate being installed between the front sealing cover and the rear sealing cover, an electrical signal interface and a power supply interface fixedly mounted on the front end of the front sealing cover, and optical cable sealing flanges at the center of both the front and rear sealing covers, with watertight optical cables installed inside the optical cable sealing flanges.

The wire led out from the signal interface is connected to the electrical signal interface, and the wire led out from the charging interface is connected to the power supply interface.

[0008] In a preferred embodiment, a first rubber sealing ring is provided between the electrical signal interface and the power supply interface and the front sealing cover to fill the gap, thereby achieving a seal between the electrical signal interface and the power supply interface and the front sealing cover.

[0009] In a preferred embodiment, both the front sealing cover and the rear sealing cover are connected to the pressure-bearing housing by multiple screws, and both the front sealing cover and the rear sealing cover are provided with a second rubber sealing ring to achieve sealing between the front sealing cover and the rear sealing cover and the pressure-bearing housing.

[0024] 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.

[0025] Refer to the instruction manual appendix Figures 1-9 This utility model provides a self-powered underwater docking box, including a pressure-bearing housing 1. The pressure-bearing housing 1 is provided with an installation plate 2 inside. A photoelectric conversion module 3 is fixedly provided on the top of the installation plate 2, and a battery pack 4 is fixedly provided on the bottom of the installation plate 2. A front sealing cover plate 5 and a rear sealing cover plate 6 are respectively installed at the front and rear ends of the pressure-bearing housing 1. The installation plate 2 is installed between the front sealing cover plate 5 and the rear sealing cover plate 6. An electrical signal interface 7 and a power supply interface 8 are fixedly provided at the front end of the front sealing cover plate 5.

[0026] like Figure 1 , Figure 2 and Figure 9 As shown, optical cable sealing flanges 9 are provided at the center of the front sealing cover plate 5 and the center of the rear sealing cover plate 6. A watertight optical cable 10 is provided inside the optical cable sealing flange 9. The watertight optical cable 10 is integrated with the optical cable sealing flange 9 by vulcanization, which can achieve the functions of sealing and tensile strength resistance.

[0027] And, as Figure 4 As shown, an optical fiber tray 11 is fixedly provided on the top of the mounting plate 2. The optical fiber tray 11 is sleeved on the outside of the photoelectric conversion module 3. The optical fiber in the watertight optical cable 10 is coiled in the optical fiber tray 11 after being fused together to ensure the transmission of optical signals. An optical interface 31 is fixedly provided at the front end of the photoelectric conversion module 3. A signal interface 32 and a charging interface 33 are fixedly provided at the rear end of the photoelectric conversion module 3. The optical fiber leading out of the optical interface 31 is fused with the optical fiber in the watertight optical cable 10 and then coiled in the optical fiber tray 11. The wire leading out of the signal interface 32 is connected to the electrical signal interface 7, and the wire leading out of the charging interface 33 is connected to the power supply interface 8.

[0028] And, as Figure 6 and Figure 7 As shown, both the electrical signal interface 7 and the power supply interface 8 are provided with a first rubber sealing ring 12 for filling gaps between them and the front sealing cover 5. The electrical signal interface 7 is a watertight socket connector, installed on the front sealing cover 5, and is sealed to the front sealing cover 5 by the first rubber sealing ring 12 provided on its outer shell.

At the receiving terminal, the optical signals are converted back into electrical signals. The battery pack 4 on the mounting plate 2 provides power to the photoelectric conversion module 3. When the battery pack 4 is low on power, it can be charged through the power supply interface 8 and the charging interface 33, enabling the junction box to be used repeatedly without external power supply. When not charging, the installed sealing plug 15 ensures the sealing performance of the power supply interface 8.

[0031] Furthermore, the pressure-bearing housing 1, the front sealing cover 5, and the rear sealing cover 6 can all be made of high-strength, corrosion-resistant materials, such as stainless steel, which has good pressure resistance and corrosion resistance, ensuring long-term stable operation of the docking box in an underwater environment. The battery pack 4 can be a rechargeable battery pack with high energy density and long service life, meeting the working requirements of the photoelectric conversion module 3 for extended periods.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
