The invention relates to the exploration of the ocean. It allows for a more reliable, fast and cost-effective transmission of energy on Board Autonomous underwater vehicle (AUV) from a Central source.
Known hermetic connector, consisting of two parts, plugs & sockets, with contact elements and the socket is provided with a sealing sleeve that is installed movably in the cavity so that between its inner end surface and the inner end surface of the socket is formed a gap, the shape of the cross section of the sealing sleeve is made identical with the shape of the cross section of the plug, the sealing sleeve is made in the form of a cylinder, the outer surface of which communicates with the internal cavity of the socket, and the inner with the outer surface of the plug, wherein the sleeve is mounted for movement towards the movement of the fork, what is the volume of the extended part of the sleeve and extended parts of the fork are equal (A. S. USSR №1453488, CL H01R 13/52, 1989).
The disadvantage of this device is the low reliability of its work in marine salt environment, when all the surface is quickly covered with salt and growths that impede the free movement of moving parts, ensuring the sealing of the conductive contacts. In addition, the specified device is required of�especialy very accurate coaxial movement of the conductive contacts toward each other, which is very difficult to realize in real conditions of operation of underwater equipment in the presence of variable and unknown ocean currents.
It is also known a device for transmission of energy and signals to the subsea apparatus containing the cable-the cable and auto electrical connectors, which are designed as a sealed halves of the transformer, installed on the elastic elements, and half with the primary winding mounted on the cable the cable, and half with the secondary winding is on the submersible, half of these transformers are mounted for sliding in the guide rails, which are equipped with stop-motion stops (A. S. USSR №1390962, CL B63B 21/66, 1996). Described the device in its technical essence is the closest to the claimed technical solution adopted for the prototype.
The disadvantage of this technical solution is that it fails to provide quality and reliable power transfer from the Central source on the APA Board, because when the inevitable gap between two disconnected halves of the transformer there are large losses. In addition, when working in a marine salt environment, all the surface is quickly covered with salt and growths, preventing the free sliding halves of the transformer in the guides and leads to distortions e�their halves. The latter further increases the gap between the halves, and as a result leads to large losses in energy transfer to the APA Board.
The objective of the claimed technical solution is to eliminate the above drawback, namely to ensure a more reliable and high-quality transfer of energy from the Central source on the APA Board.
The technical result that can be obtained when implementing the claimed solution is a fast and reliable transfer of this energy from the Central source on Board the APA by led sources and semiconductor panels receivers that do not require ensure precise alignment in space.
The problem is solved in that the device for transferring energy Autonomous underwater apparatus containing the cable-the cable that connects the energy source on Board the vessel carrier, with a sealed radiator, lowered into the water, the radiator is sealed emitter led high intensity underwater through his transparent layer and a transparent layer sealed light-receiving panels facing towards each other, comes into contact with this panel, located on Board an Autonomous underwater vehicle and which converts light into electrical energy, stored in rechargeable� the batteries of this device.
Comparative analysis of the claimed technical solution with its analogue and prototype demonstrates its compliance with the criterion of "novelty."
The claimed combination of features given in the characterizing part of the claims, allows you to more securely, quickly and with minimal losses to ensure the transfer of energy from a Central source on Board the APA by using the light flux.
The essence of the claimed technical solution is illustrated by a drawing, where the drawing shows a functional diagram of the device for transferring energy up.
Apparatus for transmitting energy Autonomous underwater apparatus (not shown) comprises a cable, the cable 1 that connects the energy source 2, ship carrier 3, hermetic emitter 4, is lowered into the water. Moreover, the emitter 4 is sealed emitter led high intensity underwater through his transparent layer 5 and the transparent layer 6 sealed light-receiving panel 7 facing towards each other, may come into contact with this panel, located on Board an Autonomous underwater vehicle and which converts light into electrical energy, stored in batteries 8 this device.
The inventive device operates as follows.
On cable cable 1 energy re�recover from the energy source 2, located on Board the carrier 3, a sealed led emitter 4, is lowered into the water. Underwater vehicle, equipped with appropriate on-Board control system, after the discharge of its battery to a certain level can come close to the emitter 4 and a non-contact way to get from the source 2 power, which is supplied thereto via the light-receiving panel 7 and stored in the battery 8. Moreover, the emitter 4 has a transparent layer 5, which is under water may come in contact (close contact) with a transparent layer 6 is also sealed light-receiving panel 7, which under the influence of the light flux coming from the radiator 4, converts it into electrical energy transmitted to the batteries.
After recharging at the signal, the onboard control system of underwater vehicle departs from the cable of the cable 1 with its led emitter 4 and continues execution of the mission.
Thus, the proposed device allows quick, reliable and efficient energy transfer to the PA Board. In this case, the electrical contact channel with the water environment is completely excluded.
