Description

Technical Field

[0001] The invention relates to the technical field of green algae monitoring, in particular to a device for monitoring the outbreak area of ​​green algae in coastal waters. Background Art

[0002] Green algae often attach to submerged rocks and wood, or float on the surface, and are a source of food or oxygen for aquatic animals. Eutrophication is a phenomenon in which excessive levels of nutrients such as nitrogen and phosphorus cause aquatic organisms, especially algae, to reproduce in large numbers, causing changes in the number of species and leading to water pollution. Therefore, monitoring of green algae areas can provide a basis for timely intervention.

[0003] A Chinese patent application with publication number CN112874702A discloses a hydrological monitoring and environmental protection boat, whose structure includes an anti-collision strip, a collecting box, a hull, and a motor. An anti-collision strip is provided on the edge of the hull, and a collecting box and a motor are provided on the hull. The collecting box is provided with a flip cover, a sampling bottle, a placement slot, a fixed base, a sampling device, and a partition. The flip cover is hingedly connected to the collecting box, and a placement slot is provided inside the collecting box, and a fixed base is provided in the placement slot. The technical solution is that the sampling bottle is matched with the sampling device, and the liquid inlet provided in the sampling bottle is connected to the water outlet pipe. The water inlet pipe can be extended with a winder to go deep into rivers for sampling. The liquid to be collected is pumped into the sampling bottle by a water pump for storage, which solves the shortcoming of the prior art that the sampling bottle will be soaked when the sample is directly loaded with the sampling bottle.

When the sampling of this area is completed, the sampling tube is continued to be driven to rotate. When the outer magnetic plate is separated from the inner magnetic plate, the liquid outlet nozzle returns to its original position under the action of the reset spring, and the first liquid outlet trough and the second liquid outlet trough are closed. The water pump is then lowered into deeper water by rollers, the water pump is started and the control valve is opened.

[0018] 3. When sampling green algae, the present invention has a filter cartridge and filter screen structure designed to avoid blockage and influence on the sampling results, because garbage particles will remain on the surface of the water body. After use, a large amount of green algae or other impurities will adhere to the surface of the filter screen. When the bottom of the hose is located in the deep layer, the cleaning motor is started and the filter screen is driven to rotate. At this time, the filter screen is cleaned under the action of the brushes on both sides. This design increases the service life of the nearshore green algae outbreak area monitoring device.
