Description

Technical Field

[0001] This invention relates to the field of underwater repeater technology, and in particular to an underwater network relay device. Background Technology

[0002] Underwater network repeaters are network communication relay devices. They are used in network communication to receive signals, process them (mainly amplification and shaping), and then retransmit them to extend signal transmission distance or connect different network segments. Their core function is to overcome signal attenuation (weakening) caused by distance in watertight cables. Without repeaters, signals weaken with increasing distance and eventually cannot be correctly identified. For large-scale ocean observation and multi-device collaborative operations, multiple repeaters are needed to build a multi-hop communication network. Data can hop from one node to a repeater, then to the next repeater or the final destination, thus achieving network coverage over a wide area. When deploying a large number of repeaters, higher requirements are needed regarding the speed and cost of repeater assembly and disassembly to enable rapid assembly, rapid deployment, and reduced cost investment.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0027] See attached document Figure 1 This embodiment provides an underwater network relay device, including: a cylindrical body 1, a first end cap 2, a second end cap 3, and a clamp 8. The two ends of the cylindrical body 1 are detachably connected to the first end cap 2 and the second end cap 3, respectively. (Refer to attached diagram.) Figure 5A bracket 4 is provided between the first end cap 2 and the second end cap 3. A circuit board 5 is mounted on the bracket 4. Both the circuit board 5 and the bracket 4 are located inside the cylinder 1. A connecting plate 02 is provided between the bracket 4 and the first end cap 2. The bracket 4 and the connecting plate 02 are fixed by screws 03. The connecting plate 02 is fixed to the first end cap 2 by screws 03. The material density of the connecting plate 02 is less than that of the first end cap 2, and the material strength of the first end cap 2 is greater than that of the connecting plate 02. Specifically, the flat-head screw 03 passes through the connecting plate 02 and is threaded to the bracket 4, and the internal hex screw 03 passes through the connecting plate 02 and is threaded to the first end cap 2. The heads of the flat-head screw 03 and the internal hex screw 03 are located on opposite sides of the connecting plate 02. In this structural design, the connecting plate 02 and the first end cap 2 are designed separately, rather than as a single piece. This reduces the weight of the device and facilitates the assembly and fixation of the bracket 4 onto the first end cap 2, preventing the circuit board 5 on the bracket 4 from shaking inside the cylinder. A first socket 6 and a second socket 7 are respectively fixed to the first end cap 2 and the second end cap 3. A clamp 8 is detachably connected to the cylinder 1, and a clamp 9 is detachably connected to the clamp 8. (See attached diagram) Figure 2 The clamp 9 includes a first clamping plate 91 and a second clamping plate 92 that are detachably connected. A clamping groove adapted to the rope 01 is provided between the first clamping plate 91 and the second clamping plate 92, and the two clamping grooves form a clamping hole adapted to the rope 1. In this invention, refer to the attached... Figure 6 Circuit board 5 is mounted on bracket 4. First socket 6 and second socket 7 are fixed to first end cap 2 and second end cap 3 respectively. Then, first socket 6 and second socket 7 are connected to circuit board 5 inside cylinder 1 respectively. (Refer to attached diagram) Figure 3 Install the first end cap 2 at one end of the cylinder 1, as shown in the attached diagram. Figure 4 Install the second end cap 3 at the other end of the cylinder 1, as shown in the attached diagram. Figure 1 Then, the clamp 8 is assembled with the cylinder 1, and the clamp 9 holding the cable 01 is fixed to the clamp 8, or the clamp 9 is fixed to the clamp 8, and then the cable 01 is clamped in the clamp 9 to complete the assembly. In this invention, the detachable first end cap 2, second end cap 3 and connecting plate 02 facilitate the assembly of the components inside the cylinder 1 and subsequent maintenance, reducing the weight of the device, especially when a large number of repeater devices are deployed on the cable 01, which can reduce the weight borne by the cable 01. The detachable clamp 8 and the detachable clamp 9 facilitate the quick deployment of the cylinder 1 on the cable 01, and also facilitate the removal of the cylinder 1 from the cable 01 for maintenance. The overall structure is simple, easy to assemble, and can achieve quick assembly and disassembly, which can effectively reduce cost investment. The circuit board 5 is used to provide the functions of a network repeater and a splitter, that is, this invention realizes the network signal repeater function to extend the communication distance, and can also power the mounted remote equipment (the first socket 6 and the second socket 7 provide signal transmission and power transmission).

[0028] Specifically, the connecting plate 02 is made of aluminum alloy, and the first end cap 2 is made of titanium alloy. This reduces weight and lowers costs.
