Multifunctional grab bucket type water-sludge collector

Abstract

The invention discloses a multifunctional grab bucket type water-sludge collector which comprises a grab bucket, a power-assisting rod used for spreading the grab bucket, and a pull rod, wherein the grab bucket comprises a first grab bucket part and a second grab bucket part, upper ends of the first grab bucket part and the second grab bucket part are movably connected, the first grab bucket part and the second grab bucket part can be opened or closed around a connecting part, through holes are formed in the upper ends of the first grab bucket part and / or the second grab bucket part, the pull rod penetrates through the through holes, one end of the power-assisting rod is movably connected with the pull rod, and the other end of the power-assisting rod is movably connected with the inner wall of the grab bucket. The multifunctional grab bucket type water-sludge collector has the beneficial effects of multiple functions, simple structure, convenience in use and low manufacture cost, and is easy to popularize in the market.

Description

technical field [0001] The invention relates to an underwater sampling device, in particular to a multifunctional grab-type water and mud sampling device used for underwater operations. Background technique [0002] At present, the mud sampling devices used in scientific research to collect shallow cement samples or sediments in deep water mainly include grab bucket mud sampling devices and column mud sampling devices. Most water sampling devices use inverted water sampling devices. These two types of equipment Can only play its single function. The general grab mud sampler often mixes the soil or sediment layers together after collecting mud samples or sediments, which fails to achieve the purpose of stratification, and it is difficult for the grab mud sampler in many cases to identify the bottom It is difficult to collect sandy sediments because it cannot be pushed into the sediment environment well and the operation is difficult. The most important thing is that most of...

Problems solved by technology

However, the most important thing is that there is currently no water collector designed for collecting overlying water with a simple structure, so it is difficult to operate and the technical means are immature

In addition, due to the many processes and the harsh environment of marine surveys, this series of processes not only increases the labor intensity of the survey and research, but also takes time and is cumbersome to operate. Moreover, the operation of each process may not be able to achieve the expected results. Effect
