The invention belongs to the technical field of underwater motion platforms, and particularly relates to an exhaust hole exhaust area control device of an underwater motion platform. The exhaust hole exhaust area control device is fixed in the underwater motion platform in advance, and the internal air pressure of the expansion balloon is equal to the water depth pressure of the underwater motion platform before motion. In the vertical movement process of the underwater movement platform, along with the reduction of water depth and pressure, an inflatable balloon expands under the action of pressure difference to drive a telescopic rod to move upwards, so that a shielding panel shields an exhaust hole from bottom to top, the exhaust area is reduced, the exhaust amount is controlled, and the control effect is good. The exhaust hole exhaust area control device is simple in appearance and structure, replacement and selection of gas media in the inflatable balloon do not need to be considered, local materials are used, cyclic utilization can be achieved, the gas pressure in the inflatable balloon can be adjusted according to different underwater movement water depths of a navigation body, and the requirements for economical efficiency and timeliness are met.
本发明属于水下运动平台技术领域,具体涉及一种水下运动平台的排气孔排气面积控制装置。本发明预先固定在水下运动平台内部,膨胀气球内部气压与水下运动平台运动前所处水深压力相等。在水下运动平台垂向运动过程中,随着水深的减小,压力的降低,膨胀气球在压差作用下发生膨胀,带动伸缩杆向上运动,从而使遮蔽面板由下往上遮蔽住排气孔,减小了排气面积,实现了对排气气量的控制,控制效果良好。本发明外形及结构简单,无需考虑膨胀气球内气体介质的更换与选择问题,就地取材,可循环利用,可根据航行体水下不同运动水深调节膨胀气球内的气体压力,满足经济性,时效性的需求。
