Problems solved by technology
However, this technology cannot prevent the frogman from invading and destroying the fence after it has been cut, nor can it determine the specific location of the intrusion
[0007] The second existing technology is to use galvanized steel wire ropes with insulating sheaths to form a fence, apply pulse voltage to the wire ropes and detect echoes to determine the specific location of direct invasion (such as cutting and impact, etc.), but this technology Cannot provide perimeter warning

Embodiment Construction
[0023] The underwater photoelectric fence of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] Such as figure 1 As shown, a single-piece optical cable fence 12 includes an optical cable 1, a cable 2, a frame 3, a cable cross clip 5, a frame fixing frame 6, a floating body 7, an above-water connection box 8, a sinking body 9, and an underwater connection box 10 .
[0025] The cable 2 is arranged vertically because of its relatively high strength, and the optical cable 1 is arranged horizontally because of its relatively low strength. Both the cable 2 and the optical cable 1 pass through the first cable fixing clip 13, the second cable fixing clip 14, 1 on the frame 3 without interruption. The first optical cable fixing clip 15 and the second optical cable fixing clip 16 are bent and folded back, and the cable 2 and the optical cable 1 are in close contact at the intersection and fixed with the cable cross fi...

The present invention provides an underwater photoelectric fence. The fence comprises: a floating body which is floated at the water surface, wherein an overwater connection box is arranged on the floating body; a sinking body which is arranged under the water surface, wherein an underwater connection box is arranged on the sinking body; and an optical cable fence which is connected between the floating body and the sinking body through a frame fixed frame, wherein the optical cable fence includes wires and cables which are mutually interlaced and arranged to form a net structure and are respectively connected with the overwater connection box and the underwater connection box. The underwater photoelectric fence fully develops the advantages of the wires and the cables, the wires are taken as isolation fences and perimeter sensing carriers and provide power supply for the underwater sensing device, and the cables are taken as isolation fences and perimeter sensing elements and provide information transmission channels for the underwater device, so that extra underwater device networks are not required.
Description
technical field [0001] The invention relates to the field of electricity, in particular to an underwater sensing technology applied in a marine environment, in particular to an underwater photoelectric fence. Background technique [0002] Fences are also often called guardrails, isolation fences (nets), protective nets, etc., and are usually composed of metal and non-metallic wires (or cables) in a mesh shape plus necessary frames. It is widely used in the isolation, defense and warning of various civil and military facilities such as roads, railways, bridges, industrial and mining enterprises, power stations, warehouses, construction parks, airports, prisons, and barracks. [0003] If the metal wires in the fence are arranged in certain rules and insulated from the grounded frame, high-voltage electric pulses can be applied to the wires, such as applying a certain tension to the wires at the same time and equipped with a tension sensor, it becomes a "tension electronic fe...
