Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, it includes motor fixing seat 1, bearing support seat 2, shaft sealing seat 3, spring leaf 4, load dumping shaft 5, runner 6, split wheel 7, ball head support 8, lead block 9, DC motor 10 and Planetary gear reducer 11, in which the motor fixing seat 1 is a cylindrical revolving body with a hollow "T" shape in the axial section, O-ring grooves are opened on both sides of the "T" shape, and O-ring grooves on one side An O-ring seal A13 is placed in the ring groove which is sealingly connected with the pressure-resistant shell of the underwater robot, and an O-ring seal B14 which is sealingly connected with the shaft seal seat 3 is placed in the O-ring groove on the other side; the DC motor 10 and the planetary gear reducer 11 are sequentially inserted in the motor holder 1 and connected in a coaxial direct connection.

Abstract

The invention relates to a ballast throwing device, specifically to a safety ballast throwing device for an underwater robot. After being decelerated by a planet gear reducer, a moment is transmitted to a ballast throwing rotating shaft by a direct current motor so as to drive a rotating wheel and an open wheel to simultaneously rotate; a bulb of a bulb supporting piece slides in an annular groove between the rotating wheel and the open wheel; when the open wheel rotates to the position of the bulb, the bulb supporting piece is thrown together with a lead block under an effect of elastic force of a spring sheet due to loss of restriction from the annular groove; after partial mass of the underwater robot is thrown, the weight of the underwater robot is less than the buoyancy force so that the underwater robot can safely surface. The safety ballast throwing device for the underwater robot has the advantages of simple and compact structure, strong module functionality, low cost, small overall dimension, good underwater sealing performance, safe and reliable ballast throwing, repeated applications, easy mounting on the underwater robot and so on.

Description

technical field [0001] The invention relates to a load throwing device, in particular to a safety throwing device for an underwater robot. Background technique [0002] An underwater robot is a movable underwater device that can perform specific tasks underwater. Underwater robots are divided into two categories: manned submersibles and unmanned submersibles according to whether they are manned. There are two types of autonomous underwater vehicles (AUVs). Due to the particularity of the underwater working environment, underwater robots are required to have higher stability, reliability and safety; among them, the safety of underwater robots is very important, and it is the last security to prevent ultra-deep damage or loss of underwater robots Barriers and reliable safety devices can ensure the safety of operators and underwater robots to the greatest extent. When the underwater robot has a fatal failure or faces a special abnormal environment, the safety device can be a...
