Embodiment Construction

[0013] Such as figure 1 , 2 , the technical solution of the present invention includes a frame body 1 supported by at least four pillars 2, and a bracket 3 with a shaft hole 4 is symmetrically provided in the frame body 1 from its top 1 / 3, and by virtue of being inserted in the shaft hole The other end of the support shaft 5 of 4 is fixed with a balance ring 6, and the balance ring 6 is provided with two snap ring shaft holes 10 inserted with the snap ring shaft 7, and the other end of the snap ring shaft 7 is fixed with a snap ring 8, The junction of the two snap rings 8 is provided with a bolt 9 for clamping and fixing the LADCP, and the line connecting the shaft holes 10 of the two snap rings and the line connecting the two shaft holes 4 are perpendicular to each other.

[0014] Because LADCP is a cylinder with a diameter of 205mm, a height of 500mm, and a weight of about 30Kg, considering the actual size of the LADCP, the height and diameter of the frame body 1 of the abo...

Abstract

The invention relates to a posture balancing self-control device of a lowered acoustic Doppler current profiler (LADCP), which comprises a frame body, wherein the frame body is at least supported by four struts; brackets with shaft holes are symmetrically arranged in the frame body and one third far away from the top, and a balancing ring is fixed by the other end of a support shaft and provided with two clamping ring shaft holes; clamping rings are fixed at the other end of an inner ring shaft which is inserted into the clamping ring shaft holes; the joint position of the two clamping rings is provided with a bolt, a connecting line of the two clamping ring shaft holes is perpendicular to a connecting line of the two shaft holes, and the LADCP is clamped and fixed by the bolt. Obviously, the invention has reasonable structure and simple process and enables the LADCP to maintain the posture that the direction of an energy converter is perpendicular to the sea level all the time in the working process.

Description

technical field [0001] The invention relates to the working attitude of a drop-in acoustic Doppler current profiler (LADCP), specifically an attitude balance automatic control device which enables the LADCP to keep the direction of the transducer perpendicular to the sea level during the working process. Background technique [0002] When using LADCP to measure ocean currents, LADCP is often fixed on a bracket. LADCP emits sound waves downward or upward through the transducer, and the echoes formed by the sound waves being reflected by scatterers moving with the ocean current in the water body are then received by LADCP. The velocity of sea water relative to LADCP is obtained from the Doppler frequency shift. When encountering a large ocean current underwater, the LADCP, together with the brackets of other instruments, is offset by the ocean current. At this time, the steel cable of the hanging instrument frame forms an included angle with the sea level. When the included an...
