Embodiment 1

[0039] For the connection mode between the buoy 12 and the arc plate 11, the optional scheme is as follows Figure 4 In the above, the buoy 12 is bonded to the arc-shaped plate 11, and the cost of adopting this solution is relatively low.

Embodiment 2

[0041] Alternatives such as Figure 5 , 6 Among them, the two ends of the buoy 12 are provided with transverse chute 16, and the transverse chute 16 is connected with the connecting portion 15 of the arc-shaped plate 11. With this structure, the distance between the arc-shaped plate 11 and the buoy 12 can be adjusted according to the strength of the surge, thereby ensuring that the arc-shaped plate 11 can still maintain a relatively vertical state when being impacted by the surge.

Embodiment 3

[0043] Alternatives such as Figure 7 , 8 Among them, the back of the arc-shaped plate 11 is provided with a connecting seat 18, and the buoy 12 is connected with the connecting seat. The connecting seat 18 is provided with a vertical chute 19, and the two ends of the buoy 12 are provided with screw rods, and the buoy 12 is connected with the vertical chute 19 through the screw rod. With this structure, the force of the curved plate 11 is more reliable, and it is suitable for occasions where the intensity of the surge is high. Further, a reinforcing plate 17 is provided, and the reinforcing plate 17 is used to support the upper back of the arc-shaped plate 11, so that the impact force of the surge wave received by the arc-shaped plate 11 is converted into a downward pressure on the buoy 12, so that the arc-shaped plate 11 Not easy to break. By adjusting up and down along the vertical chute 19, the submerged depth of the arc-shaped plate 11 can be adjusted, and this structur...

Abstract

A movable type water-level-fluctuating zone water and soil conservation wave partitioning device is characterized in that a plurality of parallel sliding rails are arranged along a water-level-fluctuating zone slope. Wave partitioning plate devices are arranged on the sliding rails. The sliding rails are fixed on the water-level-fluctuating zone slope through anchor rods. The elevation of the sliding rails is larger than the height of plants on the water-level-fluctuating zone slope. In the wave partitioning plate devices, float bowls are arranged on the reverse sides of arc-shaped plates, connecting parts are arranged at two ends of the arc-shaped plates, and guiding slots which are matched with the connecting parts in a sliding mode are correspondingly formed in two sides of the sliding rails. The wave partitioning plate devices which are installed among the sliding rails have the function of blocking and buffering surges, the surges return due to deflecting flow of the arc-shaped plates and have the function of subducting rising surges, so that erosion of the surges on soil on a bank slope is reduced, and water and soil loss on the surface of the water-level-fluctuating zone slope is reduced.

Description

[0001] This application is a divisional application of a patent application named a movable water-fluctuation zone water and soil conservation and wave isolation device, with the application date being May 20, 2013, and the application number being "2013101859041". technical field [0002] The invention relates to the field of water and soil conservation engineering in a water-fluctuation zone, in particular to a device for reducing the impact force of surges and reducing soil erosion, which is applied to river bank slopes and reservoir area water-fluctuation zone slopes. Background technique [0003] The technical problem of the present invention stems from the rapid development of hydropower station construction, and the impoundment of the reservoir causes serious water and soil loss in the drawdown zone of the reservoir area. The main reasons are the tonnage, speed, frequency, wind speed and the swell erosion caused by the periodic water level fluctuations. The Yangtze Ri...
