Remotely-controlled underwater small-size organism collector

Abstract

The invention relates to a remotely-controlled underwater small-size organism collector and relates to the field of water quality monitoring equipment; the remotely-controlled underwater small-size organism collector comprises a carrier float, a collection bottle, a frustum mesh, and a remote control; the carrier float is provided with a pushing power source and also provided with a winch unit for winding and unwinding the frustum mesh; the outlet end of the frustum mesh is connected to an opening of the collection bottle through a connector; the inlet end of the frustum mesh is also provided with an expansion device for contracting and expanding a mesh opening; the inlet end of the frustum mesh is also provided with a plurality of monitors; the carrier float is also provided with a console; the console is at least provided with a monitoring data recording module, a control module, and a signal transceiving module; data is transmitted between the console and the remote control through the signal transceiving module; the control module controls working states of the pushing power source, the winch unit, the expansion device, the connector and the monitors through a control circuit.

Description

technical field [0001] The invention relates to the field of water quality monitoring equipment, in particular to a remote-controlled underwater small-scale biological collector. Background technique [0002] Background technology: It is one of the important means of fish ecology and conservation biology research to carry out resource monitoring and biodiversity assessment by taking drifting fry and fish eggs in the early stage of fish development as objects. Fish eggs and larvae are the basis for the supplement and sustainable utilization of fish resources. Fish spawning habits and ecological investigations are of great significance to grasp the changes in the quantity of fishery resources. At the same time, many economical small-sized fish, such as whitebait, have high economic and ecological value for investigation and research on their living habits and resource assessment. In addition, phytoplankton in different water layers can not only serve as indicator organisms, r...

Problems solved by technology

However, this sampling tool has many defects. First, because there is only one traction rope, the velocity and flow rate of the water flow in the water are not stable, so the depth of the conical net in the water is not easy to control, thus it cannot correctly reflect the actual depth of the water layer. Secondly, due to the uncertain power of the ship and the small water depth, the traditional method is likely to make a part of the mud entering the seedling collection stage or the mesh opening of the cone net exposed above the water surface, resulting in errors; thirdly, the traditional method is too large. Single, unable to accurately measure some water body indicators (temperature, depth, salinity, brightness, PH value, dissolved oxygen, flow velocity, etc.) at the corresponding underwater sampling depth, which affects the effectiveness of sampling; in addition, sampling ships cannot enter Some specific areas, such as shallow water areas, fish protection areas, areas with roadblocks, etc., make the traditional method impossible to implement; finally, when continuous sampling is carried out in the field, the traditional cone net tends to flow a lot of impurities and garbage in actual operation , such as dead branches and some aquatic plants, it is easy to block the entrance of the seedling collector, which is not conducive to cleaning and collecting samples
