Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of deep-sea optical communication devices, and in particular to optical communication devices for use in deep-sea environments. Background Art

[0002] With the continuous advancement of deep-sea resource development, optical communications can achieve high-speed and stable data transmission in complex environments with its high bandwidth, low latency, strong anti-interference and long-distance transmission capabilities, showing unique technical advantages. Therefore, optical communications are gaining more and more attention in the field of deep-sea communications. In the high-pressure environment of the deep sea, traditional antenna designs need to be placed in watertight cabins to ensure the safety of the equipment under extreme pressure. In order to cope with the challenges of the deep-sea high-pressure environment and improve communication efficiency, modern deep-sea optical communication equipment mostly adopts a large-aperture optical window design.

[0003] However, when using the above-mentioned method to collect deep-sea light beams using deep-sea optical communication devices, the following technical problems often occur:

[0004] Watertight cabins with large-aperture optical windows are extremely difficult to design and process, and have extremely high requirements for material strength, which leads to an increase in the size and weight of the equipment, easily blocking the optical path and possibly causing optical signal attenuation, thereby reducing communication efficiency. These factors have greatly increased the difficulty of designing and manufacturing deep-sea optical communication equipment, and increased costs and complexity. Summary of the invention

[0015] Optionally, the second reflector is placed opposite to the detector target surface. When in use, the plano-concave lens divides the received light beam into two beams from the middle, and then the plano-convex lens refracts the two beams to the main reflector.

Specifically, the reasons why most deep-sea optical communication devices have high pressure resistance requirements, large size, and high weight are that watertight compartments with large-aperture optical windows are extremely difficult to design and process, and the requirements for material strength are also extremely high, resulting in an increase in the size and weight of the equipment, increasing the possibility of obstruction to optical signals, and may cause optical signal attenuation, thereby reducing communication efficiency.

On the other hand, the above-mentioned optical communication device for deep-sea environment is composed of only various brackets and various reflectors to form an open design, without the need for watertight cabin packaging, and has a relatively smaller volume and weight than the traditional large-caliber optical antenna encapsulated in a watertight cabin. In addition, the seawater on both sides of the lens can balance the pressure, reduce the difficulty of design and processing, reduce the requirements for material strength, and greatly reduce the processing cost. As a result, not only can the pressure resistance requirements be reduced while ensuring the daylighting rate, but also the volume and weight of the equipment can be effectively reduced, reducing the manufacturing cost.

[0040] Optionally, each connecting column 8 may be a hollow structure, wherein both ends of each connecting column 8 are closed structures, which are used to prevent seawater from entering when in use.

The material of the telescopic control buckle 10 may include, but is not limited to, nylon, ABS plastic, and polypropylene, etc., which can be corrosion-resistant in a deep-sea environment and the material itself has elasticity, and other restrictions are not made. The outer connecting column 81 and the inner connecting column 82 may both be hollow columns to further reduce the weight of the optical communication device used in a deep-sea environment.

[0046] The above optional embodiment, as an inventive point of the embodiment of the present disclosure, solves the technical problem that "the structure of the deep-sea optical communication device is fixed after installation, and it is not easy to carry and has poor flexibility". The factors that lead to the fixed structure after installation, the inconvenience of carrying and the poor flexibility are as follows: on the one hand, the deep-sea optical communication device is usually an unadjustable structure after installation, and cannot be further adjusted according to the actual situation. On the other hand, the length of some components of the deep-sea optical communication is long after disassembly, which is not convenient to carry. If the above factors are solved, the problem of inconvenience in carrying and poor flexibility can be solved. In order to achieve this effect, the embodiment of the present disclosure transforms the connecting column of the optical communication device for deep-sea environment into a retractable and adjustable structure. On the one hand, the above-mentioned external connecting column and the inner connecting column are both hollow structures, and the above-mentioned telescopic control buckle is also a lightweight material with a small volume, which will not add much extra weight to the above-mentioned optical communication device for deep-sea environment. On the other hand, the above-mentioned telescopic control buckle can adjust the length of the above-mentioned connecting column as needed through the above-mentioned adjustment buckle, so as to achieve the purpose of making the above-mentioned optical communication device for deep-sea environment more flexible to carry and use. Therefore, without affecting the original function and without increasing much weight, the optical communication device for deep sea environment is made easier to carry, and after installation, it remains an adjustable structure, thereby improving flexibility.

[0047] Some embodiments of the present disclosure provide an optical communication device for use in a deep-sea environment, which can reduce the pressure resistance requirements while maintaining efficient light energy collection and transmission capabilities, and can effectively reduce the size and weight of the equipment, thereby reducing manufacturing costs. Specifically, the reasons why most deep-sea optical communication devices have high pressure resistance requirements, large size, and high weight are that watertight compartments with large-aperture optical windows are extremely difficult to design and process, and the requirements for material strength are also extremely high, resulting in an increase in the size and weight of the equipment, increasing the possibility of obstruction to optical signals, and may cause optical signal attenuation, thereby reducing communication efficiency. These factors have greatly increased the difficulty of designing and manufacturing deep-sea optical communication equipment, and increased the cost and complexity of the system. Based on this, some embodiments of the present disclosure provide an optical communication device for a deep-sea environment, wherein the optical communication device for a deep-sea environment includes a conical lens, a main reflector, a second reflector, a detector target surface, a lens mounting bracket and a connecting bracket, wherein the lens mounting bracket includes a first lens mounting groove, a second lens mounting groove and at least one connecting column, and the at least one connecting column is connected between the first lens mounting groove and the second lens mounting groove; the main reflector is fixed to the first lens mounting groove, the conical lens is fixed to the second lens mounting groove, and the center points of the main reflector and the conical lens are on the central axis of the lens mounting bracket; the second reflector is fixed to the at least one connecting column through the connecting bracket, and the second reflector is close to the conical lens, and the center point of the second reflector is on the central axis; the detector target surface is fixed to one of the at least one connecting column. On the one hand, the above-mentioned optical communication device for deep-sea environment uses the above-mentioned conical lens to scatter the light beam and then refract it separately to form a gap in the central axis of the light beam, and the position of the above-mentioned second reflector is placed in the above-mentioned gap, which alleviates the problem of light path obstruction caused by the complex internal structure of the deep-sea optical communication device and improves the antenna focusing efficiency. On the other hand, the above-mentioned optical communication device for deep-sea environment is composed of only various brackets and various reflectors to form an open design, without the need for watertight cabin packaging, and has a relatively smaller volume and weight than the traditional large-caliber optical antenna encapsulated in a watertight cabin. In addition, the seawater on both sides of the lens can balance the pressure, reduce the difficulty of design and processing, reduce the requirements for material strength, and greatly reduce the processing cost. As a result, not only can the pressure resistance requirements be reduced while ensuring the daylighting rate, but also the volume and weight of the equipment can be effectively reduced, reducing the manufacturing cost.
