Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a river bend concave bank protection device for water conservancy projects, which solves the problem of controlling the erosion of the concave bank of the river channel through padding stone sand at present, which has high consumption costs and low governance efficiency. It is considered that there is too much intervention In the end, it will also cause the concave bank of the river to turn into a convex bank, causing irreparable damage to the river's landform, which is not conducive to the management of the river.

Embodiment 1

[0038] Such as Figure 1-3 As shown, the present invention provides a technical solution: a river bend concave bank protection device for water conservancy engineering, including a protective outer contact plate 1 and an inner attachment plate 2, and the outer protective contact plate 1 adopts an outwardly convex arc surface structure, the inner attachment plate 2 adopts an inwardly concave arc surface structure, and the protective outer contact plates 1 are fixedly connected by a deformation adjustment mechanism 3, and the deformation adjustment mechanism 3 close to the outer side is rotatably connected with a limiting side plate 4, and the inner attachment plate The horizontal position of 2 is uniform and equidistantly provided with conduction slots 5, and the left and right sides of the inner attachment plate 2 are fixedly connected with mounting clamps 6, and the upper and lower ends of the conduction slot 5 pass through the fluid resistance increasing mechanism 7 It is fi...

Embodiment 2

[0040] Such as Figure 4 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: the driving fan wheel 9 includes a supporting shaft 91, and the upper and lower ends of the supporting shaft 91 are connected to the internal rotation of the feeding window 8, A right-angle scraper 92 is uniformly and fixedly connected to the outer side of the support shaft 91 . The right-angle scraper 92 adopts two right-angle structures, which can stably transmit the shoveled sand, and at the same time, the right-angle side absorbs the impact force of the water flow to provide power for the transmission of the sand.

Embodiment 3

[0042] Such as Figure 4 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a river bend concave bank protection device for water conservancy engineering, the right-angle scraper 92 adopts two right-angle structures, and the right-angle scraper The vertical position of the side near the outer side of the sheet 92 is evenly spaced and fixedly connected with guiding tapered grooves 93 . The guide cone groove 93 adopts a tapered structure with a large outside and a small inside, so as to increase the power of the water flow to guide and rotate, and ensure sufficient power for filling the concave bank.

Abstract

The invention discloses a river curve concave bank protection device for the water conservancy project, and relates to the technical field of water conservancy. The river curve concave bank protection device comprises protection outer contact plates and inner attaching plates. Each protection outer contact plate is of an outwards-convex cambered surface structure, and each inner attaching plate is of an inwards-concave cambered surface structure. The protection outer contact plates are fixedly connected through deformation adjusting mechanisms, the deformation adjusting mechanism close to the outer side is rotationally connected with a limiting side plate, conduction open grooves are evenly formed in the transverse position of the inner attaching plates at equal intervals, mounting clamping plates are fixedly connected to the left sides and the right sides of the inner attaching plates, material adding windows are formed in the middles of the protection outer contact plates, and driving fan wheels are rotationally connected to the middles of the interiors of the material adding windows. According to the river curve concave bank protection device for the water conservancy project, the effect that the protection plate is arranged to buffer scouring of bank water flow to concave bank soil is achieved, and primary protection of a concave bank is achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy, in particular to a river bend concave bank protection device for water conservancy engineering. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals. [0003] Concave Bank A river bank that ...
