Crane arm with supercapacitor energy storage for wave compensation bus side energy management

Abstract

The invention provides a super capacitor energy storage lazy arm for wave compensation busbar side energy management, and belongs to the technical field of ocean operation. The super capacitor energystorage lazy arm for wave compensation busbar side energy management comprises a workbench. The workbench is provided with a supporting arm and a grabbing disc. A support column is fixed to the workbench. A fixing frame is fixed to the workbench. A steel wire rope is fixed between the fixing frame and the support column. The support column is rotationally provided with a first rotation arm and a second rotation arm which are fixed to one end of the supporting arm. A first overturning arm, a second overturning arm, a third overturning arm and a fourth overturning arm are hinged to the grabbingdisc in the circumferential direction at equal intervals. The supporting arm is provided with a super capacitor energy storage device. The super capacitor energy storage lazy arm can more effectivelyconduct wave compensation on lazy arm adjustment, and accordingly, offshore operation stability and safety are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of marine operations, and relates to a supercapacitor energy storage boom used for energy management on the side of a wave compensation busbar. Background technique [0002] In today's marine industry, with the deepening of resource development and exploration, offshore operating platforms and ships have become important tools for transportation and operations. The transportation and replenishment of goods on the sea is an important operation of the marine industry, especially the transportation of fresh water and food and the launching of lifeboats are life-threatening operations. However, there is a big difference between sea operations and land operations. Ocean currents swing, sink and float freely, making it very difficult to take in and out both cargo and equipment at sea, and prone to accidents. Therefore, on the premise of this series of dangerous operations, the development of wave compensation tec...

AI Technical Summary

Problems solved by technology

[0004] However, when a crane with a wave compensation system is used for offshore operations, the crane itself has flexibility, so that the stability of the grabbed object cannot be guaranteed when the sea state exceeds level 3 during the grabbing process.

At the same time, when the hook of the crane is lowered, it will drive the generator to run, and the electric energy will be converted into DC through the rectifier, thereby raising the voltage of the DC bus; The inverter transforms into a three-phase voltage to supply power to the motor, which creates the problem of energy recovery and utilization after wave compensation
