Self-hovercraft compartment body for reducing additional hydrodynamic load of launching type ship lift
The invention relates to a self-hovering ship chamber body for reducing additional hydrodynamic load of a launching type ship lift, which adopts the principle that a bottom bed board of a ship chamber is arranged to be of a flat bottom structure, an outer ring beam, an inner ring beam, grid beam longitudinal beams, grid beam cross beams, exhaust holes and the like are arranged below the bottom bed board, part of gas at the bottom of the ship chamber is locked, and an air cushion is automatically formed. The direct acting force of water on the bed board at the bottom of the ship chamber is isolated, and therefore additional hydrodynamic loads such as adsorption force and slapping force in the process that the ship chamber enters and exits water are reduced. By the adoption of the ship chamber body, the water entering and exiting operation speed of the ship chamber of the launching type ship lift can be greatly increased, the problem that the downstream butt joint efficiency is low is solved, meanwhile, after the ship chamber body is adopted, the adsorption force and the slapping force are zero in the water entering and exiting process, and the load is not increased along with the increase of the size of the ship chamber. The device can also be applied to a ship chamber structure of a large-scale launching type ship lift, and the problem that large adsorption force and slapping force are generated in the process that the ship chamber of the large-scale ship lift enters water is solved.
本发明涉及一种减小下水式升船机附加水动力荷载的自气垫船厢体型，其原理是将船厢底铺板设置为平底结构，在底铺板下布置外圈梁、内圈梁、网格梁纵梁、网格梁横梁、排气孔等，锁住船厢底部部分气体，自动形成气垫，隔离了水体对船厢底铺板直接作用力，从而减小船厢出入水过程中的附加水动力荷载，如吸附力与拍击力。采用该船厢体型可以大幅提高下水式升船机船厢出入水运行速度，解决其下游对接效率低的问题，同时，采用该船厢体型后出入水过程吸附力及拍击力为零，该荷载不随船厢尺寸增大而增大，因此，也可适用于大尺度下水式升船机船厢结构中，解决大尺度升船机船厢入水过程产生较大的吸附力及拍击力问题。
