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

Embodiment 1
[0033] Such as Figure 1-Figure 5 As shown, this embodiment provides a seabed-based monitoring system, including a bottom-sitting device 11 and an observation device 12, the observation device 12 and the bottom-sitting device 11 are detachably connected, and the observation device 12 is also connected with an active booster device, which It is used to disengage the observation device 12 from the bottom device 11 .
[0034] By arranging an active assisting device, when the observation device 12 and the sitting device 11 need to be disengaged, the observation device 12 can be actively applied to the observation device 12 to disengage the force from the sitting device 11, instead of the observation device 12 only passively relying on the The buoyancy produced by the buoyancy body 13 makes it float up, thereby significantly improving the ability of the observation device 12 to break away from the bottom device 11, greatly reducing the poor posture of the bottom device 11 or mud bl...

The invention belongs to the technical field of underwater observation operation equipment, and relates to a seabed-based monitoring system. The seabed-based monitoring system comprises a bottom-sitting device and an observation device, the observation device is detachably connected with the bottom-sitting device, the observation device is further connected with an active power assisting device, and the active power assisting device is used for enabling the observation device to be separated from the bottom-sitting device. A technical problem that separation operation of carrying equipment anda seabed base is unreliable is solved, and a technical effect of obviously improving the capacity of the observation device for separating from the bottom-sitting device is achieved.
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 ...
