Split type deep-sea movable television grab bucket

Abstract

The invention discloses a split type deep-sea movable television grab bucket which comprises an electric mechanism and a grab bucket mechanism, and the electric mechanism and the grab bucket mechanismare arranged in a split mode, wherein the electric mechanism is connected with the grab bucket mechanism through high-strength ropes, a pipeline is arranged between the electric mechanism and the grab bucket mechanism, and the pipeline comprises an electric circuit and a hydraulic pipeline. According to the scheme, a grab bucket part is separated from an electric part, the grab bucket part and the electric part assembled respectively, and the grab bucket part is connected with the electric part through ropes such as stainless steel chains, so that the grab bucket and the electric part are simpler and more convenient to assemble and convenient to disassemble, and the maintenance cost is reduced; the independent grab bucket mechanism is smaller in volume and lighter in weight than the integral grab bucket mechanism, so that samples can be conveniently distributed and grabbed, and the independent grab bucket mechanism can cope with more complex submarine topography; impact vibration generated during working basically exists on the grab bucket resistant to impact vibration, a large number of electric elements and other components arranged on the electric mechanism are protected, the service life of the television grab bucket is greatly prolonged, and the cost is saved.

Description

technical field [0001] The invention relates to a split-type deep-sea movable TV grab, which belongs to the field of deep-sea ocean bottom mining equipment. Background technique [0002] With the development of marine technology, marine resources such as manganese nodules, cobalt crusts, combustible ice, sulfide, etc. are of great attraction to the development of modern society. Others, such as seabed rock samples, seabed sediments, etc. is of great significance. At present, there are not many sampling methods for seabed resources. At first, the method of grabbing trawling was gradually abandoned because trawling caused great damage to the seabed and was prone to loss. Later, there was a grab that was lowered to the seabed by a steel cable, but it did not have a TV function. There were huge unknowns about the ability to collect samples of seabed resources. Especially in complex seabed terrain, the grab was prone to overturning, impact, and jamming. , so that the sampling s...

AI Technical Summary

Problems solved by technology

[0004] At present, the latest TV grab adopts an integrated solution, that is, the grab mechanism, hydraulic system and control system of the TV grab are assembled together, and the assembly is relatively complicated.

When the integrated TV grab grabs resource samples under some complex seabed terrain, such as seamount slopes, due to the large size and weight of the whole TV grab, it is not convenient to deploy and grab samples

Moreover, when the grab grabs rock samples or collides, it may generate a large impact vibration. Since the entire device is rigidly connected, the vibration will be transmitted to the entire device through the bucket body, which will affect the impact resistance of the entire TV grab. The requirements are high, and it is easy to cause damage; and if a certain part or component fails, it may cause the entire grab to be disassembled for maintenance, which is extremely inconvenient to maintain and the maintenance cost is also high
