Description

An integrated device for environmental protection dredging and ecological restoration

Technical field:

The utility model belongs to the technical field of ecological restoration, in particular to an integrated device for environmental protection dredging and ecological restoration.

Background technique:

Prevention and treatment of eutrophication and ecosystem degradation is the top priority of water environment governance. The composition of pollutants in the sediment is complex, and the main pollutants are heavy metals and organic pollutants. The nitrogen and sulfur content in the sediment is relatively high, which is one of the main reasons for the phenomenon of black and odorous water bodies. Sediment dredging can remove the internal sources of polluted water bodies and reduce the release of sediment pollutants to water bodies. It is an important measure to control pollution sources of polluted rivers and lakes. However, dredging too deep during the dredging process will cause damage to the original river ecosystem, and mechanical agitation during the dredging process will cause pollutants to diffuse and cause secondary pollution. Therefore, it is necessary not only to prevent the spread of pollutants but also to rebuild the damaged ecosystem during dredging operations. Restoring or rebuilding submerged plant communities is considered to be an effective measure in water ecological restoration. The current submerged plant planting methods mainly include artificial cutting method, seed sowing method and throwing method. It is of practical significance to study a way to prevent secondary diffusion of pollutants after dredging and quickly plant submerged plants to rebuild the ecosystem.

The Chinese patent CN209243804U, whose publication date is August 13, 2019, discloses a small-scale normal maintenance type integrated device for dredging and processing river sediment, including a hull, a mud discharge pipe and a mud truck. A mud-cutting roll is arranged on the hull, and a rotating shaft and a mud suction port are arranged inside the mud-cutting roll. The mud discharge pipe is connected with the mud suction port. The bottom mud in the mud suction port can enter the mud transport truck through the mud discharge pipe through suction. The device can continuously transfer the inhaled bottom mud by using the mud-cutting roll during the dredging treatment process, greatly reduces the gravity burden of the mud-cutting roll and the dredging hull, and improves the dredging efficiency. Its shortcoming is that the device performs normal sediment dredging on the river channel, ignoring the diffusion of pollutants caused by mechanical agitation during the dredging process of the mud cutting roll, resulting in secondary pollution.

Chinese patent CN109457749A with a publication date of March 12, 2019 discloses a device and method for dredging underwater polluted sediment, the device comprising a vessel anchored to an underwater bed and having a ladder that can be viewed downwards from the water surface A body container of water is located and provided at its free end is a cutting tool comprising a plurality of digging elements arranged about a common axis of rotation. The cutting tool includes a channel for the excavated bed material adjacent to the inlet end of a discharge device for the excavated bed material, the discharge device includes a carrier for the bed material driven by the machine, the carrier includes two conveyor belts, which are in opposite directions Rotate each other. This device can effectively dredge underwater riverbeds without causing large amounts of sediment spillage, especially at relatively large depths and with relatively hard beds, unlike other mechanical excavators such as dredging cranes or bucket dredger) can significantly improve efficiency. Its disadvantage is that the dredging depth cannot be controlled during the dredging process, and once the dredging is too deep, the river bottom ecosystem will be destroyed.

The Chinese patent CN216775472U with the publication date of June 21, 2022 discloses a planting device for submerged plants, which includes a cylinder and a holding rod.

The part makes the bottom cover block the bottom of the cylinder; the holding rod is fixed on the top of the cylinder and extends upward; a disassembly mechanism of the closing part is also provided to connect with the closing part for disassembling the closing part. The device puts the submerged plants wrapped in soil in the cylinder, extends into the bottom of the water, and then unfolds the bottom cover of the cylinder to fix the submerged plants at the position to be planted, which can be planted in shallow water or at a deeper depth. It can be planted in deep water bodies, and the survival rate of planted submerged plants is improved.
