Collection device of duckweeds or submerged plants

Abstract

The invention discloses a collection device of duckweeds or submerged plants, comprising a ship body, a storing device arranged on the ship body and a power device for driving the collection device to move, and further comprising a gathering device, wherein the gathering device comprises a hard pipe, a hose, a gathering groove, a pump and a hoisting device; the hard pipe is fixedly arranged on the ship body and an outlet of the hard pipe is communicated with the storing device; the hose is connected with the hard pipe; the gathering groove is communicated with the hose; the pump is arranged between the gathering groove and the hose; and the hoisting device is used for driving the gathering groove to hoist in a vertical direction. The gathering groove is in a funnel shape and the gathering groove gradually becomes small from an inlet of the gathering groove. The collection device disclosed by the invention can be vertically hoisted along a water surface, so that duckweed plants above the water can be collected and can be submerged in the water, and the submerged plants at the water bottom can be gathered. The collection device disclosed by the invention can be used for filtering the collected duckweeds or submerged plants, and collecting the duckweeds or the submerged plants as much as possible.

Description

technical field [0001] The invention relates to a harvesting device for duckweed or submerged plants. Background technique [0002] At present, the floating debris collection ships widely used in rivers at home and abroad are generally divided into bucket type or conveyor belt type; the two types of salvage ships are very efficient in collecting floating garbage on the water surface and aquatic plants such as water hyacinths. For small and rootless aquatic plants such as duckweed, because duckweed is too small and scattered, and generally only floats at a height of about 1 cm on the water surface, the density of duckweed per unit area is much smaller than that of water hyacinth and other plants. The growth characteristics of duckweed make duckweed Distributed over the entire water surface, it is difficult to ensure efficient and comprehensive collection by traditional bucket or conveyor belt collection methods. To remove duckweed, rootless weeds, Manjianghong and other f...

Problems solved by technology

[0002] At present, the floating debris collection ships widely used in rivers at home and abroad are generally divided into bucket type or conveyor belt type; The efficiency of aquatic plants such as water hyacinth is very high, but when collecting small and rootless aquatic plants such as duckweed, because duckweed is too small and scattered, and generally only floats at a height of about 1 cm above the water surface, the density of duckweed per unit area Far smaller than water hyacinth and other plants, the growth characteristics of duckweed make duckweed distributed on the entire water surface, so it is difficult to ensure efficient and comprehensive collection by traditional bucket or conveyor belt collection methods

To remove duckweed, rootless weeds, Manjianghong and other floating small stem weeds, sundries and even floating water plants of the water turtle family. There are also submerged plants in the water body, such as algae, which are somewhat corrupted in the water body. The lower layer (the space below 1 meter of the water surface) is also scattered in the water body. It is difficult to reach such a depth and the collection range is limited by the bucket type or conveyor belt type collection method
