Description

Technical Field

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

[0002] With the continuous advancement of deep-sea resource development, optical communications, with its high bandwidth, low latency, strong anti-interference capabilities, and long-distance transmission capabilities, can achieve high-speed and stable data transmission in complex environments, demonstrating unique technical advantages. Consequently, optical communications are gaining increasing attention in the field of deep-sea communications. In the high-pressure environment of the deep sea, traditional antenna designs must be placed in watertight compartments to ensure the safety of the equipment under extreme pressure. To meet the challenges of the high-pressure deep-sea environment and improve communication efficiency, modern deep-sea optical communication equipment often uses large-aperture optical window designs.

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

[0004] Watertight compartments with large-aperture optical windows are extremely difficult to design and manufacture, 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, which may cause optical signal attenuation and thus reduce communication efficiency. These factors have greatly increased the difficulty of designing and manufacturing deep-sea optical communication equipment, and increased cost and complexity. Summary of the Invention

[0013] Optionally, the second lens mounting groove is a hollow structure, and the second lens mounting groove includes a plano-convex lens mounting bracket and a plano-concave lens mounting bracket, and the plano-concave lens mounting bracket is arranged directly above the plano-convex lens mounting bracket, and the conical lens includes a plano-convex lens and a plano-concave lens, and the plano-convex lens is arranged in the plano-convex lens mounting bracket, and the plano-concave lens is arranged in the plano-concave lens mounting bracket, and the center point of the plano-concave lens mounting bracket and the center point of the plano-convex lens mounting bracket are on the same straight line.

[0014] Optionally, the detector target surface is a hollow structure, and the detector target surface further includes a fixing structure, and the detector target surface is fixed to one of the at least one connecting column through the fixing structure.

[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.

[0017] Some embodiments of the present disclosure provide an optical communication device for use in deep-sea environments, which can reduce pressure requirements while maintaining efficient light energy collection and transmission capabilities, effectively reducing the size and weight of the device and reducing manufacturing costs. Specifically, the reason why most deep-sea optical communication devices have high pressure requirements, large size and high weight is 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 device, 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 slot, a second lens mounting slot and at least one connecting column, and the at least one connecting column is connected between the first lens mounting slot and the second lens mounting slot; the main reflector is fixed to the first lens mounting slot, the conical lens is fixed to the second lens mounting slot, 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 columns. On the one hand, the above-mentioned optical communication device for deep-sea environments uses the above-mentioned conical lens to scatter the light beam and then refract it separately, forming a gap in the center axis of the light beam. The position of the above-mentioned second reflector is located within the above-mentioned gap, which alleviates the problem of light path obstruction easily caused by the complex internal structure of the deep-sea optical communication device and improves the antenna's focusing efficiency. On the other hand, the above-mentioned optical communication device for deep-sea environments is composed only of various brackets and various reflectors, forming an open design, which does not require watertight compartment packaging. Compared with traditional large-diameter optical antennas enclosed in watertight compartments, it has a relatively smaller volume and weight. In addition, the seawater on both sides of the lens can balance the pressure, reducing the design and processing difficulty, lowering the requirements for material strength, and greatly reducing processing costs. As a result, not only can the pressure resistance requirements be reduced while ensuring the light rate, but the volume and weight of the equipment are also effectively reduced, reducing manufacturing costs.

For example, the lens mounting bracket may include 4 connecting columns 8, and correspondingly, the connecting bracket may include 4 second reflector connecting brackets 9, and each second reflector connecting bracket 9 is fixedly connected to a connecting column 8.

[0035] In some embodiments, the detector target surface 5 can be fixed to one of the at least one connecting post 8. A chimeric structure can be provided at one end of the detector target surface 5.

The first lens mounting groove 6 can be a hollow structure, which can further reduce the weight of the optical communication device for deep-sea environment. The material of the fixing ear 61 can be consistent with that of the first lens mounting groove 6. The fixing ear 61 provided in the first lens mounting groove 6 is used to fix the main reflector 1. Among them, the structure of the main reflector is not unique. For example, Figure 2As shown, the above-mentioned main reflector 1 can also be replaced by a honeycomb main mirror 201.

[0037] Alternatively, as Figure 1 As shown, the outer side of the first lens mounting groove 6 may include at least one connecting post mounting groove 62. The number of the at least one connecting post mounting groove 62 may be the same as the number of the at least one connecting post 8. The material of the connecting post mounting groove 62 may be the same as that of the first lens mounting groove 6. The connecting post mounting groove 62 is provided with a connecting hole. The dimensions of both ends of the connecting post 8 are smaller than the dimensions of the connecting hole. One end of each connecting post 8 may be disposed in a connecting post mounting groove 62.

[0038] Alternatively, as Figure 1 As shown, the outer side of the second lens mounting groove 7 may include at least one connecting post mounting groove 62. In the installed state, the connecting post mounting groove 62 provided on the outer side of the second lens mounting groove 7 corresponds one-to-one with the connecting post mounting groove 62 provided on the outer side of the first lens mounting groove 6, and the number of the connecting post mounting grooves 62 is the same. The number of the at least one connecting post mounting groove 62 that the second lens mounting groove 7 may include is the same as the number of the at least one connecting post 8. The material of the second lens mounting groove 7 may be the same as that of the first lens mounting groove 6.

[0039] Alternatively, as Figure 1 As shown, each connecting post mounting slot 62 is provided with a fixing screw hole on the outside. The connecting post mounting slot 62 also includes a fastening bolt. The fixing screw hole is used to receive the fastening bolt for fastening the connecting post 8. The fastening screw hole can be used to fasten the connecting post 8 within the connecting post mounting slot 62 with the fastening bolt. The material and model of the fastening bolt are not limited, as long as they can achieve a fastening effect and are of suitable size.

[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 hollow structure of the connecting column 8 can be used to further reduce the weight of the optical communication device for deep-sea environment.

[0041] Alternatively, as Figure 1As shown, the second lens mounting groove 7 may be a hollow structure. The second lens mounting groove 7 being a hollow structure may further reduce the weight of the optical communication device for deep-sea environments. The second lens mounting groove 7 may include a plano-convex lens mounting bracket 72 and a plano-concave lens mounting bracket 71.

[0043] Alternatively, as Figure 1 As shown, the second reflector 2 and the detector target surface 5 can be placed opposite to each other, so that the detector target surface 5 can better receive the light beam focused from the second reflector 2. In use, the plano-concave lens 3 can divide the received light beam into two beams from the middle. The plano-convex lens 4 then refracts the light beam divided into two beams onto the main reflector 1, and the main reflector 1 can reflect the received light beam to the second reflector 2. The second reflector 2 can reflect the light beam and focus it on the detector target surface 5. There can be a gap in the middle of the light beam divided into two beams. The second reflector 2 is in the gap. The second reflector 2 is in the gap, which can reduce the blocking effect of the second reflector 2 on the light path.

[0044] Alternatively, as Figure 1As shown, the above-mentioned plano-concave lens mounting bracket 71 can be set on the outer end surface of the above-mentioned second lens mounting groove 7.

The above-mentioned plano-concave lens mounting bracket 71 and the plano-convex lens mounting bracket 72 can both be a cross bracket structure with a center for setting a lens groove. The methods of fixing the above-mentioned plano-concave lens mounting bracket 71 and the above-mentioned plano-convex lens mounting bracket 72 to the above-mentioned second lens mounting groove 7 can include but are not limited to: welding, hot melting and bolt fixing. The above-mentioned plano-convex lens mounting bracket 72 and the above-mentioned plano-concave lens mounting bracket 71 can only retain the necessary structures for setting and fixing the above-mentioned plano-convex lens 4 and the above-mentioned plano-concave lens 3, so as to further reduce the weight of the above-mentioned optical communication device for deep-sea environment. The center point of the above-mentioned plano-concave lens mounting bracket 71 can be on the same straight line as the center point of the above-mentioned plano-convex lens mounting bracket 72, so as to make the received and refracted light paths more accurate.

[0045] Alternatively, as Figure 3-4 As shown, each connecting column 8 may include an outer connecting column 81 and an inner connecting column 82. The outer connecting column 81 is larger than the inner connecting column 82. The outer connecting column 81 may also include a telescopic control buckle 10. The material of the telescopic control buckle 10 may include, but is not limited to, nylon, ABS plastic, and polypropylene, as long as the material is corrosion-resistant and elastic in deep-sea environments. Other limitations are not imposed. Both the outer connecting column 81 and the inner connecting column 82 may be hollow columns to further reduce the weight of the optical communication device used in deep-sea environments. The outer connecting column 81 may be inserted into the outer side of the inner connecting column 82 to form a telescopic structure. One end of the telescopic control buckle 10 may be a buckle fixing bolt 101. The buckle fixing bolt 101 may be made of the same material as the telescopic control buckle 10.

In use, when the adjustment buckle 102 is open, the end of the telescopic control buckle 10 with the adjustment buckle 102 may be larger than the inner connecting post 82. The connecting post 8 may be a telescopic structure. When the adjustment buckle 102 is closed, the end of the telescopic control buckle 10 with the adjustment buckle 102 engages the inner connecting post, securing the position of the inner connecting post.

[0046] The above-mentioned optional embodiment, as an inventive feature of the embodiments of the present disclosure, addresses the technical problem of "deep-sea optical communication devices having a fixed structure after installation, making them difficult to carry and having poor flexibility." The factors contributing to this fixed structure, difficulty in portability, and poor flexibility after installation are as follows: First, deep-sea optical communication devices are typically non-adjustable after installation, preventing further adjustments based on actual conditions. Second, some components of deep-sea optical communication devices are long after disassembly, making them difficult to carry. Addressing these factors can resolve the portability and poor flexibility issues. To achieve this, the embodiments of the present disclosure modify the connecting posts of the deep-sea optical communication device into a retractable and adjustable structure. First, both the external and internal connecting posts are hollow, and the retractable control buckle is made of lightweight material and is relatively small, thus not adding significant weight to the deep-sea optical communication device. Furthermore, the retractable control buckle allows the length of the connecting posts to be adjusted as needed via the adjustment buckle, thereby making the deep-sea optical communication device more flexible to carry and use. Therefore, without affecting the original function and without increasing much weight, the above-mentioned optical communication device for deep-sea environment is made more portable, and the structure remains adjustable after installation, thereby improving flexibility.

[0047] Some embodiments of the present disclosure provide an optical communication device for use in deep-sea environments, which can reduce pressure requirements while maintaining efficient light energy collection and transmission capabilities, effectively reducing the size and weight of the device and reducing manufacturing costs. Specifically, the reason why most deep-sea optical communication devices have high pressure requirements, large size and high weight is 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 device, 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 slot, a second lens mounting slot and at least one connecting column, and the at least one connecting column is connected between the first lens mounting slot and the second lens mounting slot; the main reflector is fixed to the first lens mounting slot, the conical lens is fixed to the second lens mounting slot, 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 columns. On the one hand, the above-mentioned optical communication device for deep-sea environments uses the above-mentioned conical lens to scatter the light beam and then refract it separately, forming a gap in the center axis of the light beam. The position of the above-mentioned second reflector is located within the above-mentioned gap, which alleviates the problem of light path obstruction easily caused by the complex internal structure of the deep-sea optical communication device and improves the antenna's focusing efficiency. On the other hand, the above-mentioned optical communication device for deep-sea environments is composed only of various brackets and various reflectors, forming an open design, which does not require watertight compartment packaging. Compared with traditional large-diameter optical antennas enclosed in watertight compartments, it has a relatively smaller volume and weight. In addition, the seawater on both sides of the lens can balance the pressure, reducing the design and processing difficulty, lowering the requirements for material strength, and greatly reducing processing costs. As a result, not only can the pressure resistance requirements be reduced while ensuring the light rate, but the volume and weight of the equipment are also effectively reduced, reducing manufacturing costs.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
