River duckweed fishing and collecting device for ecological restoration

Abstract

The invention discloses a river duckweed fishing and collecting device for ecological restoration. The device comprises a device body, wherein a mounting cover plate is arranged above the device body,a connecting rod is fixedly connected to the tops, close to one side, of the two inner side walls of the device body, inserting plates are fixedly connected to the positions, close to the two sides,of the lower surface of the mounting cover plate, inserting grooves are formed in the top ends of the two side walls of the device body correspondingly, thread grooves II are formed in the positions,close to one side, of the upper ends of the two side walls of the device body correspondingly, and mounting bolts are arranged at the corners, close to one side, of the upper surface of the mounting cover plate in a penetrating mode. The river duckweed fishing and collecting device has the quick mounting and dismounting functions, so that the device can be cleaned and overhauled conveniently, theduckweed fishing and collecting range can be expanded, the good fishing and collecting function is achieved, the flowing speed of water is increased, reverse flow of duckweeds is prevented, the situation that the interior of the device is blocked and consequently duckweed fishing and collecting are affected is also avoided, and the duckweed fishing and collecting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, in particular to a river surface duckweed fishing and collecting device for ecological restoration. Background technique [0002] Duckweed is the general name of Duckweed plants, and it is the smallest flowering plant in the world. It grows fast and is considered to be one of the most promising strategic raw materials for future biomass liquid fuels. At present, duckweed is a common floating plant on the water surface in all provinces of my country. It reproduces and grows extremely fast. A large number of duckweeds block the sunlight, which is not conducive to the photosynthesis of plankton in the water. The reduction in the contact area between oxygen and the water surface causes hypoxia in the water. Fish die, and the water quality in the river channel becomes poor or even corrupt. Therefore, the massive breeding of duckweed is the cause of indirect water pollution. At present, t...
