Description

Technical Field

[0001] The utility model relates to a salvaging device, in particular to a device for automatically salvaging blue algae on a river surface. Background Art

[0002] In some nutrient-rich water bodies, some cyanobacteria often reproduce in large numbers in the summer and form a layer of blue-green and fishy-smelling foam on the water surface, which is called "water bloom". Large-scale cyanobacteria outbreaks are called "green tides" (corresponding to red tides in the ocean). Green tides cause water quality to deteriorate, and in severe cases, they deplete oxygen in the water and cause fish deaths. What's more serious is that some species of cyanobacteria (such as Microcystis) also produce microcystins (MCs for short). About 50% of green tides contain a large amount of MCs. In addition to being directly toxic to fish, humans and animals, MCs are also an important cause of liver cancer.

[0003] For this purpose, it is necessary to regularly salvage the blue algae on the water surface. The existing automatic blue algae salvaging vessels on the market are expensive to purchase (about 600,000 yuan each), and non-automatic blue algae salvaging vessels cannot salvage and clean up all the blue algae on the river surface in a short period of time. Utility Model Content

[0004] The utility model aims to provide a device for automatically salvaging blue algae on the river surface. The device can salvage and clean up all the blue algae on the river surface in a short time, and the device has a simple structure, is easy to use and has low cost.

[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0016] Embodiment of the utility model: a device for automatically salvaging blue algae on the river surface, such as Figure 1-2 As shown, it includes a hull 1, a conveyor belt 2 connected to a driving mechanism is obliquely arranged at the tail of the hull 1, a wave-shaped screen 3 is fixed on the surface of the conveyor belt 2, a fixed groove 4 is arranged on the hull 1 below the head end of the conveyor belt 2, a plurality of collecting barrels 5 are placed side by side in the fixed groove 4, and the side walls of the fixed groove 4 and the collecting barrel 5 are provided with drainage holes 6.

[0017] The hull 1 is a mowing boat hull, and the conveyor belt 2 is the original mowing boat structure. During use, the driving mechanism of the original conveyor belt 2 drives it to rotate, and the conveyor belt 2 will drive the screen 3 to rotate together. During the rotation of the screen 3, the blue algae on the water surface will be salvaged, and the blue algae that are gathered together will adhere to the surface of the screen 3, and the blue algae and water will be classified by the screen 3. After the blue algae rotates to the head end of the conveyor belt 2 with the screen 3, it falls into the collection bucket 5 under the action of gravity for collection. The blue algae accumulates and compresses in the collection bucket 5, and the remaining water is filtered out and discharged into the river through the fixed groove 4 and the drainage hole 6 on the collection bucket 5, ensuring that the collection bucket 5 can collect a large amount of blue algae. The fixed groove 4 is mainly used to fix the collection bucket 5 to prevent the collection bucket 5 from sliding arbitrarily. After the collection bucket 5 is full of blue algae, a new collection bucket 5 can be replaced. The reason why the sieve 3 is provided instead of using the conveyor belt 2 of the original mowing boat to salvage the blue algae is that during the process of using the conveyor belt 2 to salvage the blue algae, the blue algae will slide down along the surface of the conveyor belt 2, and the separation of the blue algae and water cannot be achieved.

[0018] The fixed groove 4 is divided into a plurality of chambers along the length direction by a plurality of partitions 7, and a collecting bucket 5 is placed in each chamber to prevent the collecting buckets 5 from being squeezed together and to avoid the inconvenience of lifting the collecting buckets 5 out of the fixed groove 4 when squeezed together.

[0019] The length and width of each chamber are slightly larger than the diameter of the collecting bucket 5 by 1 to 2 cm, and the height of the chamber is lower than the height of the collecting bucket 5, so that the collecting bucket 5 can be easily lifted out of the chamber and placed in.

[0020] Guardrails 8 are provided on both sides of the hull 1 to provide safety protection for personnel and the collection bucket 5. The collection bucket 5 filled with blue algae is placed on the hull 1 and is prevented from sliding into the water by the guardrails 8.

[0021] The surface of the hull 1 is a flat structure, which is convenient for placing the collecting bucket 5. Secondly, the water discharged through the collecting bucket 5 and the drainage hole 6 of the fixing groove 4 will flow to the surface of the hull 1. The flat structure of the hull 1 makes it easy for water to flow out. If a hold is provided like other hulls, the discharged water will easily flow into the hold, and the water in the hold will need to be scooped out later, which is more troublesome.

[0022] The fixing groove 4 is movably placed on the hull 1. Since the fixing groove 4 is relatively long and made of metal, it has a certain weight, so it is not easy to slide when placed on the hull 1. It is also convenient to adjust the position of the device and to receive the fallen blue algae. When the hull 1 needs to salvage water plants, the fixing groove 4 can be moved away, which is convenient to use. The trough of the screen 3 is tied to the conveyor belt 2 with iron wire, which is convenient to disassemble and install. When the hull 1 needs to salvage water plants, the screen 3 can be removed by removing the binding wire, which is convenient for salvaging water plants.

[0023] The utility model can gradually salvage and clean up the blue algae on the river surface by modifying the existing mowing boat, and the overall modification cost is about 3,000 yuan, saving the cost of purchasing automatic blue algae salvage boats (600,000 yuan per boat). After the modification, the blue algae on the river surface can be gradually cleaned up, and there is no need to worry about the blue algae floating on the water surface in hot weather. After the modification, two salvage workers can salvage 30,000 square meters of blue algae on the river surface in one boat per day, which provides salvage workers with a more relaxed and convenient salvage method.
