Seabed based monitoring system

Abstract

The invention belongs to the technical field of underwater observation operation equipment, and relates to a seabed-based monitoring system. A seabed-based monitoring system, including a bottom-sitting device and an observation device, the observation device and the bottom-sitting device are detachably connected, and the observation device is also connected with an active booster, and the active booster is used to make all The observation device is separated from the bottom sitting device. It solves the technical problem of unreliable detachment operation between the carrying equipment and the seabed base, and achieves the technical effect of significantly improving the ability of the observation device to detach from the bottom-seat device.

Description

technical field [0001] The invention belongs to the technical field of underwater observation operation equipment, and in particular relates to a seabed-based monitoring system. Background technique [0002] The ocean plays a pivotal role in the survival and development of human beings. With the exploration and development of marine resources in our country, the application of underwater observation instruments is increasing day by day. Due to the complex working environment and harsh conditions, the traditional deck winch and submersible buoy system can no longer meet the requirements of this special environment. [0003] At present, the monitoring methods for the deep water environment are not perfect, and the data obtained by various traditional technical means are limited. Therefore, the collection of large-depth near-bottom in-situ observation data is particularly important. However, all kinds of observation instruments must first be integrated on a carrying platform ...

AI Technical Summary

Problems solved by technology

The submersible buoy is usually composed of a buoy, a cable for hanging instruments and equipment, an acoustic releaser and the counterweight connected below. It is easy to salvage and recover multiple equipments; the disadvantage is that the observation equipment is far away from the seabed

The seabed base is usually composed of a bracket with instruments and equipment, an acoustic releaser, a recovery cable, and a counterweight. The advantage is that the equipment carried can be observed close to the seabed; the disadvantage is that it is difficult to ensure its bottoming posture when it is released. Or it is difficult to recover if it is trapped in the mud; when recovering, it needs to be pulled up by a lifting device through the recovery cable, and the operation is difficult

However, in such a scheme, if there is a lot of silt on the equipment, the buoyancy of the equipped equipment will not be enough to lift the weight of the equipment itself and the silt on the equipment, or the sediment such as silt will enter the equipment and the seabed foundation. In between, or due to the unsatisfactory posture when it landed on the seabed, the angle at which the equipment is separated from the seabed foundation deviates greatly from the vertical direction, and the buoyancy is not enough to overcome the corresponding frictional resistance, which will make it impossible for the equipment carried detachment from the seabed
