Description

Electric ship power station

Technical Field

The invention relates to a power exchanging station for exchanging power for ships, and belongs to the technical field of new energy.

Background

Ships are frequently used in areas such as lake areas, riverways, offshore areas and the like; particularly, ships such as yachts and the like are often used as tourism items or patrol rescue facilities in tourist scenic spots near water; at present, conventional ships mostly adopt fuel engines, are not friendly to the environment, and particularly in tourist attractions, the fuel engines not only can generate huge roaring sound, but also can generate a large amount of smoke dust and pungent smell to influence the environment of the scenic spots, and meanwhile, the sightseeing experience of tourists is also influenced.

Therefore, at present, a large number of ships, particularly sightseeing speed boats and other ships in scenic spots, are changed into electric ships, a high-power motor is adopted to drive a propeller to work, and power is supplied through a power type storage battery. However, the capacity of the storage battery is always limited, and the use demand of the ship is high in the scenic spot at the peak of tourists.

The existing ship berthing, charging and butting positioning method such as Chinese patent publication No. CN110435467A needs to charge for a long time after a ship is berthed, and obviously cannot meet the high-frequency use requirement of the ship. Therefore, a scheme for replacing the power of the ship is generated by combining with actual requirements.

An automatic battery replacement system, an intelligent dock and a battery replacement method with a Chinese patent publication number of CN112224086A provide a battery replacement method, but a specific battery replacement mechanism is not introduced and disclosed in detail; the chinese patent publication No. CN113859036a discloses an intelligent energy battery replacement system and a battery replacement method, and does not disclose a specific battery replacement mechanism. The automatic wharf power exchanging system and method disclosed in the chinese patent publication No. CN112009302a utilize an AGV to transport a battery (an energy collection box 50) and then utilize a shore-based crane to hoist, the battery adopted is a large battery with container specification, and is only suitable for large ships, and the whole system has certain reference significance for power exchanging operation of small ships, but cannot be directly transferred to power exchanging function of small ships. The system for replacing the shipborne container type battery with the Chinese patent publication No. CN112026580A is also used for replacing the battery of the large battery with the container specification.

Therefore, a special battery replacement station needs to be designed for small electric ships such as sightseeing boats and the like to meet the corresponding battery replacement requirement and realize reliable battery replacement operation.

One of the improvements of the electric ship power changing station of the present invention is that a fixing mechanism 5 for ship power changing is provided near the water inlet and outlet passage B, as shown in fig. 6, an installation position schematic diagram is provided; the fixing mechanisms 5 are preferably arranged on two sides above the water inlet and outlet channel B, and are used for fixing the ship 1 to be replaced from two sides; of course, it is also possible to install on one side only, i.e. a fixed shore base where it is necessary to push the vessel 1 to the other side.

The fixing mechanism 5 is preferably installed below the region of the battery replacing mechanism 2, namely, the installation position of the battery pack 11 on the ship 1 is fixed, so that the situation that the part shakes along with water flow to influence the battery replacing operation is avoided. And the fixing mechanism 5 is preferably arranged above the water surface to fix the shipboard on two sides above the ship 1 underwater, so that the soaking and slipping failure is avoided, and the equipment is prevented from being corroded and rusted or damaged in the water.

As shown in fig. 7 and 8, the overall structure of the fixing mechanism 5 is schematically illustrated, and includes a fixing bracket 51, a telescopic driving element 52, a truss 54, and a buffer 55; the fixed support 51 is fixedly arranged on a shore a or a floating wharf type wharf C, a plurality of telescopic driving elements 52 are arranged on the fixed support 51, and the telescopic driving elements 52 can be air cylinders or hydraulic cylinders; the cylinders of the telescopic driving element 52 are parallel to each other, the axis of the cylinder is perpendicular to the water inlet and outlet channel B, and the telescopic driving element 52 is arranged towards the water inlet and outlet channel B; the end part of an output rod 53 of the telescopic driving element 52 is connected with a truss 54, and a buffer piece 55 is arranged on the truss 54; the cushion member 55 is a rubber cushion member, preferably a cushion bladder.

Further, a telescopic arm 46 is arranged between the gear ring 42 and the clamp platform 45; the telescopic arm 46 is a telescopic mechanism with a plurality of layers sleeved; when the clamp platform 45 is driven by the steel wire rope to lift, the telescopic arm 46 moves in a telescopic manner. But the telescopic arm 46 can be used for eliminating the horizontal swinging or torsion of the clamp platform 45 when only being hoisted by the steel wire rope; when the gear ring 42 rotates, the wire rope reel 44 is driven to rotate, and the clamp platform 45 is driven to rotate through the telescopic arm 46.

The rotation mechanism constituted by the ring gear may be installed between the telescopic arm 46 and the jig stage 45, and may rotate only the jig stage 45.

Further, as shown in fig. 14, the bottom of the telescopic arm 46 is connected to the clamp platform 45 through a plurality of springs 47; therefore, the clamp platform 45 is movably connected with the telescopic arm 46, the clamp platform 45 can be rotated by the telescopic arm 46 within a large angle range, and meanwhile, when the clamp platform is in butt joint with the frame 111, small-angle self-adaptive adjustment is carried out.

A plurality of lifting claws 48 are arranged below the clamp platform 45; preferably more than 1 of said lifting claws 48 are provided on each side of the rectangle.
