Underwater article lifting and delivering device based on toothed-bar linkage principle

Abstract

The invention provides an underwater article lifting and delivering device based on a toothed-bar linkage principle, and relates to the technical field of ocean engineering. The underwater article lifting and delivering device based on the toothed-bar linkage principle comprises a positioning plate. A threaded ring is fixedly connected to the front side of the positioning plate. The positioning plate is circular, and the circle center of the positioning ring coincides with that of the threaded ring. Six uniformly-distributed lightening holes are formed in the surface of the positioning plate.The radius of the threaded ring is greater than the distance from each of three half gears to the midpoint of the positioning plate, and the three half gears are all engaged with the threaded ring. According to the underwater article lifting and delivering device based on the toothed-bar linkage principle, connecting rods rotate upwards or downwards to change the distance between every two of a first-stage support, a second-stage support, a third-stage support and a fourth-stage support, so that storage and height adjustment are facilitated, and the linkage and stability of all structures areensured; meanwhile, by adoption of the toothed-bar linkage principle, operation is more convenient and effortless, and the operation time is shortened; and in addition, the height is adjusted, so thatthe practicability and applicability of the underwater article lifting and delivering device are improved.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an underwater article lifting and delivering device based on the principle of rack-and-rod linkage. Background technique [0002] When monitoring the seabed structure and sea conditions in offshore or shallow sea areas, divers are often required to collect rocks or other samples from the seabed and take them out to facilitate subsequent scientific research. Due to the complicated types of samples, the overall weight is relatively heavy. Large, divers consume a lot of physical strength in the process of carrying samples to the surface, which poses a certain threat to the safety of divers. At the same time, different types of samples need to be placed separately, but for safety reasons, they are often collected by divers. The samples were taken out at one time, which had a certain impact on the sorting and classification in the later stage. In addition, even if the crew ...

[0002] When monitoring the seabed structure and sea conditions in offshore or shallow sea areas, divers are often required to collect rocks or other samples from the seabed and take them out to facilitate subsequent scientific research. Due to the complicated types of samples, the overall weight is relatively heavy. Large, divers consume a lot of physical strength in the process of carrying samples to the surface, which poses a certain threat to the safety of divers. At the same time, different types of samples need to be placed separately, but for safety reasons, they are often collected by divers. The samples were taken out at one time, which had a certain impact on the sorting and classification in the later stage. In addition, even if the crew on board used the method of taking out the samples in stages by using cables or other tools, the impact of seawater often caused the location of the cables to be dropped. Deviations occur that affect the progress of the work
