Embodiment 1

[0071] like Figure 1-Figure 2 As shown, a constant flow replenishment system for floodplains is characterized in that it includes a reservoir 1, a constant flow discharge subsystem 2 and a uniform outflow subsystem 3;

[0072] The reservoir 1, the constant flow water discharge subsystem 2 and the uniform outflow subsystem 3 are connected in sequence;

[0073] Reservoir 1 has the functions of being a water source, sinking sand and simulating an ecological lake;

[0074] The constant-flow water discharge subsystem 2 is used to adjust the outflow of the reservoir 1 to realize constant-flow water discharge;

[0075] The uniform outflow subsystem 3 is used to control the uniform outflow of the floodplain water volume, and maintain the water level to evenly flood the floodplain at the set overflow depth.

[0076] In the embodiment of the present invention, the cofferdam height H of the reservoir 1 1 1.5m; design water level high H 2 1.2 meters, dead water level high H 3 0.3 me...

Embodiment 2

[0080] One side of the reservoir 1 in the above-mentioned embodiment 1 is provided with a water outlet, and the water outlet communicates with the constant flow water discharge subsystem 2;

[0081] figure 1 The constant flow water discharge subsystem 2 in includes a water flow channel 25, a lifting cofferdam device and a floating ball 24; one end of the water flow channel 25 is communicated with the water outlet of the reservoir 1, and the other end is connected with the uniform flow subsystem 3; the lifting The cofferdam device is arranged on the water flow channel 25 to separate the reservoir 1 from the uniform outflow subsystem 3; the floating ball 24 is connected with the lifting cofferdam device.

[0082] Among them, the water flow channel 25 forms the transition section between the reservoir 1 and the uniform outflow subsystem 3, providing space for the installation of the lifting cofferdam device; the floating ball 24 is arranged in the reservoir 1 and connected with t...

Embodiment 3

[0106] like Image 6As shown, the uniform outflow subsystem 3 in the above-mentioned embodiment 2 includes an overflow pool 32 and an arc-shaped water baffle 31;

[0107] The section of the overflow pool 32 is semicircular, the top of one end of the overflow pool 32 is flush with the top of the other end of the water passage 25 and seamlessly connected, and the other end of the overflow pool 32 is smoothly connected with one end of the beach area 4 to be replenished;

[0108] One end of the arc-shaped water-passing baffle 31 is fixedly arranged in the overflow pool 32, and the other end is suspended in the overflow pool 32, and the opening end of the arc-shaped water-passing baffle 31 faces the side of the rectangular thin-walled weir 22;

[0109] A plurality of water passing holes 33 are uniformly arranged on the arc-shaped water passing baffle plate 31 .

[0110] In the embodiment of the present invention, the arc-shaped water baffle 31 divides the overflow pool 32 into two...

Abstract

The invention discloses a beach-area constant-flow water supplementing system and method. The beach-area constant-flow water supplementing system comprises a water storage pool, a constant-flow waterreleasing subsystem and a uniform outflowing subsystem. The constant-flow water releasing subsystem of the beach-area constant-flow water supplementing system can automatically adjust the height of aweir plate according to the change of the water level of the water storage pool to keep the weir head constant, and thus the outflow rate is kept constant; meanwhile by being matched with the uniformoutflowing subsystem, the water level can be kept to uniformly flood beaches at the set overflow depth; therefore manpower and material resources are effectively saved, the beach-area water supplementing efficiency is improved, the benefits are increased, and meanwhile the problems of beach-area scour erosion and small beach land water supplementing covering area caused by direct water releasing for beach flooding are avoided; and the system is easy to operate and high in automation degree.

Description

technical field [0001] The invention belongs to the technical field of ecological water replenishment in floodplains, and in particular relates to a constant-flow water replenishment system and method for floodplains. Background technique [0002] A delta, or alluvial plain of an estuary, is a common landform. The silt and other impurities carried by the rushing rivers meet the seawater with a much higher salt content than fresh water at the estuary, flocculate and deposit, and gradually become new wetlands on the banks of the estuaries, and then form delta plains. The top of the delta points up the river, and the outer edge faces the sea, which can be seen as the "base" of the triangle. [0003] With the development of economy and society, in order to prevent floods, many rivers entering the sea have built flood control dams. Although this protects both sides of the river in the delta region from the threat of floods, it also causes the beach in the delta to lose the chan...
