一种活塞式上浮下潜机构和水下设备
摘要：
本发明涉及一种活塞式上浮下潜机构和水下设备，包括驱动机构、丝杆、活塞和活塞缸，活塞设置在活塞缸内；丝杆的一端插入活塞缸内并与活塞固定连接；丝杆的另一端伸出活塞缸外并与驱动机构连接，丝杆在驱动机构的驱动下做直线往复运动；其中，活塞在丝杆的带动下在活塞缸内来回移动，实现活塞缸的进水或出水，驱动机构提供驱动力，驱动丝杆作直线往复运动，丝杆带动活塞在活塞缸内来回运动，活塞缸进水或出水；进水时，活塞缸的重量增加，安装有本发明的水下设备实现下潜；出水时，活塞缸的重量减少，安装有本发明的水下设备上浮。本发明采用丝杠传动，传动效率高，结构简单紧凑。
摘要（英）：

The invention relates to a piston type floating and diving mechanism and underwater equipment. The mechanism comprises a driving mechanism, a lead screw, a piston and a piston cylinder; the piston isarranged in the piston cylinder; one end of the lead screw is inserted in the piston cylinder, and is fixedly connected with the piston; the other end of the lead screw extends out of the piston cylinder, and is connected with the driving mechanism; the lead screw is driven by the driving mechanism to perform a linear reciprocating motion; the piston is driven by the lead screw to perform a reciprocating motion in the piston cylinder to realize water feeding or water drainage of the piston cylinder; the driving mechanism provides driving force to drive the lead screw to perform a linear reciprocating motion; the lead screw drives the piston to perform a reciprocating motion in the piston cylinder to realize water feeding or water drainage of the piston cylinder; during water feeding, the weight of the piston cylinder is increased, so that the underwater equipment provided with the mechanism realizes diving; and during water drainage, the weight of the piston cylinder is reduced, so that the underwater equipment provided with the mechanism realizes floating. The mechanism adopts the lead screw transmission to achieve high transmission efficiency, and is simple and compact in structure.
