[0005] In the existing design, the chain transmission is used as the transmission mechanism of the ultra-short baseline lifting device, although it can meet the requirements of driving the transducer shaft to move up and down, but when the chain transmission method is used, a sprocket needs to be installed, and its structure is complicated and requires a large amount of space. There is a large space, and a constant instantaneous transmission ratio cannot be guaranteed during operation. Once worn, it is prone to failures such as gear jumping, which brings great difficulties to the precise positioning of the ultra-short baseline system.

The invention brings forward a precision positioning elevating apparatus used for an ultrashort baseline. The apparatus further improves precision and stability of up-down movement of an ultrashort baseline energy converter; the apparatus increases the movement distance of an energy converter shaft on condition that up-down movement of the energy converter is guaranteed; and the apparatus saves space and greatly reduces the complexity of the whole apparatus.
Description
technical field [0001] This patent relates to a lifting device for an ultra-short baseline positioning system, in particular to a precision positioning lifting device for an ultra-short baseline, and relates to the field of marine machinery measurement. Background technique [0002] The ultra-short baseline positioning system (USBL) is an underwater acoustic positioning system that works on the principle of acoustics. Its basic principle is that the transceiver transducer sends an interrogation signal to the underwater target. Send a response signal after receiving the signal from the USBL transceiver transducer. The sending and receiving transducer measures the distance between the target and the sending and receiving transducer through the round-trip time of sending and receiving the response signal. Since multiple hydrophones are installed on the transceiver, the position of the underwater target relative to the transceiver transducer can be determined through intersecti...
