Technical Field
[0001] This utility model relates to the field of marine engineering technology, specifically to an electric catamaran barge. Background Technology
[0002] Shore power is a high-power variable frequency power supply device designed and manufactured specifically for harsh operating environments such as ships and shore docks. It is widely used on ships, shipbuilding and repair shops, ocean drilling platforms and shore docks to provide power for ship electrical equipment. Although shore power has been vigorously promoted in recent years, its cost is still huge, resulting in a low usage rate of shore power in major ports across the country.
[0003] In practical applications, the number of ships anchored in anchorages is usually much greater than the number of ships anchored in ports. However, the current shore power facilities in ports are still unable to meet the power needs of ships anchored in anchorages. The existing shore power facilities cannot cover ships anchored in anchorages, which has become an urgent problem to be solved.
[0004] In addition, since the anchorage energy storage and charging barges are not powered and are far from the shore, they need to be replaced with containerized power supplies by other vessels; therefore, we are making technical improvements to the current barges to meet the usage requirements. Utility Model Content
[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing an electric catamaran barge that can not only replace the box-type power supply of the anchorage energy storage and charging barge, but also charge the ships berthed in ports and coastal anchorages.
[0006] The technical problem to be solved by this utility model is achieved through the following technical solution: an electric catamaran barge, which includes a hull, comprising;
[0007] A pair of plates, connected as one unit by a connecting bridge, including a deckhouse and a containerized power supply;
[0008] A bridge-type container crane, which is situated on top of a pair of plates, consists of a bridge and a container lifting mechanism;
[0009] The cable tray consists of a metal box-type support structure and a track. The metal box-type support structure is a box-type frame structure formed by connecting several crossbeams and several diagonal braces. The track is horizontally installed on the top of the box-type frame.
[0010] The container lifting mechanism includes a self-propelled trolley mounted on and traveling along a track, and a container spreader for lifting single containers is installed at the bottom of the self-propelled trolley.
[0011] The shore power connection equipment includes a rotating base mounted on a sheet body, an electric winch on the rotating base on which a cable is wound, and a telescopic arm with one end mounted on the rotating base and the other end mounted on a cable delivery device for releasing the cable.
[0012] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the electric catamaran barge described above, wherein the self-propelled trolley includes a metal frame, wheels that can move along the track are installed at the four corners of the metal frame, and a motor that is connected to the wheels for transmission on the metal frame to drive the self-propelled trolley to move along the track.
[0013] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the electric catamaran mentioned above uses a containerized power supply equipped with a lithium iron phosphate battery system.
[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0015] (1) The electric catamaran barge adopts a catamaran hull layout, has a large deck working space, can store more containerized power supplies, has better stability, is conducive to lifting operations in complex sea conditions, meets the power supply needs of multiple scenarios, and also meets the requirements of green environmental protection.
[0016] (2) The configured bridge-type container crane and shore power connection equipment are more conducive to hoisting operations. Compared with the fixed rotary crane, which can only cover a part of the deck area, the container power supply is centrally arranged under the bridge. The electric catamaran barge can cover all container power supply through hoisting, which is highly feasible to build and effectively reduces the carbon emissions of ships berthed at anchor.

[0023] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.
[0024] Example 1, referring to Figure 1-5 An electric catamaran barge, comprising a hull, which includes;
[0025] A pair of plates 1, which are conventional structures in the shipbuilding industry, so their specific materials, shapes and structures will not be described here. Their middle parts are connected as one piece by a connecting bridge 2, which is also a conventional structure in the shipbuilding industry, so its specific materials, shapes and structures will not be described here. It includes a deckhouse 3 and a containerized power supply 4, which is a containerized power supply 4 equipped with a lithium iron phosphate battery system.
[0026] A bridge-type container crane, which is placed on top of a pair of plates 1, consists of a bridge and a container lifting mechanism, with a maximum capacity of nearly 2000kWh;
[0027] The cable tray consists of a metal box-type support structure 6 and a track 7. The metal box-type support structure 6 is a box-type frame structure formed by connecting several crossbeams and several diagonal braces. The track 7 is horizontally installed on the top of the box-type frame.
[0028] The container lifting mechanism includes a self-propelled trolley mounted on and traveling along the track 7. A container spreader 5 for lifting single containers is installed at the bottom of the self-propelled trolley. The container spreader 5 is existing technology, and its specifications and models can be selected according to the usage requirements.
[0029] The self-propelled vehicle includes a metal frame 12, which is roughly square. Wheels 13 that can move along the track 7 are installed at the four corners of the metal frame 12. Motors that are connected to the wheels 13 and drive the self-propelled vehicle to move along the track 7 are also provided on the metal frame 12.
