Dam slope protection device

Abstract

The invention relates to the technical field of dam slope protection, and discloses a dam slope protection device. The dam slope protection device comprises a plurality of dam protection units installed on a dam, the dam protection units comprise water feeding mechanisms, water diversion mechanisms and protection grilles, wherein the water feeding mechanisms comprise pump bodies and blade drive assemblies, the blade drive assemblies comprise blade wheel hubs, blade devices circumferentially and uniformly arranged on the blade wheel hubs and rotating shafts coaxially arranged with the blade wheel hubs, the blade devices comprise blades and elastic pieces; the blades are installed on the blade wheel hubs through the elastic pieces, the upstream faces of the blades are directly faces the water flow direction, one ends of the rotating shafts are fixedly connected with the blade wheel hubs, and the other ends of the rotating shafts are connected with the power input ends of the pump bodies.According to the dam slope protection device, the water flow in a river channel can be conveyed to the upper part of the dam through a pipeline, electric energy is not consumed in the water conveyingprocess, the energy is saved, the environment is protected, the growth requirement of the slope protection grass is guaranteed, the better slope protection effect is achieved, the maintenance cost ofthe slope protection is reduced, and the dam slope protection device is easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of dam slope protection, in particular to a dam slope protection device. Background technique [0002] When choosing grass species on dams, we should choose plants with well-developed root system and strong soil-fixing ability, so as to prevent the river from scouring the dam for a long time and accelerate the water and soil loss of the dam. Bahia Grass is one of the common greening grass species planted on embankments. The successfully planted Bahia Grass lawn is very strong in drought resistance, but there is a problem that this kind of grass is not resistant to waterlogging. Therefore, in the event of river swollen In some cases, the water flow will submerge the grass on the embankment, and the non-waterlogging-tolerant grass is difficult to survive. In addition, the rise of the water level will affect the stability of the soil layer of the embankment, resulting in soil erosion and protection failure. The...

Bahia Grass is one of the common greening grass species planted on embankments. The successfully planted Bahia Grass lawn is very strong in drought resistance, but there is a problem that this kind of grass is not resistant to waterlogging. Therefore, in the event of river swollen In some cases, the water flow will submerge the grass on the embankment, and the non-waterlogging-tolerant grass is difficult to survive. In addition, the rise of the water level will affect the stability of the soil layer of the embankment, resulting in soil erosion and protection failure. Therefore, we choose to plant waterlogging-resistant grass on the embankment. Plants can avoid water and soil erosion caused by long-term submersion of plants by water, but this kind of waterlogging-tolerant plants will also have the problem of not being drought-tolerant, and long-term water shortage will also affect the survival of this type of slope protection plants

Under the current circumstances, in order to ensure the growth of waterlogging-resistant plants on the embankment, it is necessary to ensure timely water supply for this type of plant. The traditional water supply method requires manual watering on time and pumping irrigation, which will undoubtedly consume manpower and material resources. It will also increase the maintenance cost of slope protection
