Description
Technical Field
The utility model relates to a hydropower house tailrace arrangement structure, and belongs to the technical field of hydraulic buildings.
Background
The power generation plant is a main junction building of a hydropower station and mainly comprises an underground plant and a ground plant. For a ground plant, the axis of a tail water channel of the ground plant is generally intersected with a natural river channel at a small angle so as to facilitate the return of water to a groove. However, the factory layout sometimes has to be limited by the topography and geological conditions, which may lead to the intersection of the axis of the tailrace and the natural river in a large angle, and may cause the direct impact of the main river flow on the tailrace, so as to cause the problems of poor outflow flow state of the tailrace, sediment accumulation of the tailrace, and the like.
Disclosure of Invention
The technical problems to be solved by the utility model are as follows: provides a tailrace arrangement structure of a hydropower house, which aims to solve the problems of poor flow state of the tailrace water flow, fouling of the tailrace and the like.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a hydroelectric power plant tailrace arrangement structure, including setting up the hydroelectric power plant region in river course one side, be provided with the tailrace pool in the bottom of hydroelectric power plant region, the tailrace pool passes through tailrace and river course intercommunication, the tailrace has the first guide wall that is close to the upstream side of river course and is close to the second guide wall that the river course low reaches side set up, the tailrace passes through changeover portion ditch and river course intercommunication, the changeover portion ditch sets up along the river course flow direction, the side wall of changeover portion ditch is including the first barricade of locating in the river course and the second barricade of locating this one side river bank of hydroelectric power plant region place, the tip of first guide wall extends to in the river course and is connected with first barricade, the second barricade is connected with the second guide wall.
Further is: the second retaining wall is slope-attached concrete arranged on the river bank.
Further is: the upstream end of the first retaining wall extends to the river bank on the upstream side of the tailrace.
The beneficial effects of the utility model are as follows: the tail water channel is communicated with the river channel through the transition section water channel, and the transition section water channel is arranged along the river channel flow direction, so that the water flow state of the tail water channel outlet is good, and the tail water channel outlet can be smoothly connected with the water flow of the main river channel. Meanwhile, the first retaining wall located in the river channel can resist flood of the main river channel, and the problems of sediment accumulation of the tail water channel and the like are solved. The utility model is especially suitable for the condition that the axis of the tail water channel is intersected with the natural river channel at a large angle.
Drawings
Fig. 1 is a schematic plan layout of the present utility model.
Fig. 2 is a schematic view of section A-A of fig. 1.
The marks in the figure: 1-river channel, 2-tail canal, 21-first guide wall, 22-second guide wall, 3-transition section canal, 31-first retaining wall, 32-second retaining wall, 4-power generation plant, 5-site line and 6-pressure pipeline.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the present utility model includes a hydropower house area (i.e. an area where a power plant 4 is located) disposed at one side of a river channel 1, a tailrace pool is disposed at the bottom of the hydropower house area, the tailrace pool is communicated with the river channel 1 through a tailrace channel 2, the tailrace channel 2 has a first guide wall 21 disposed near the upstream side of the river channel 1 and a second guide wall 22 disposed near the downstream side of the river channel 1, the tailrace channel 2 is communicated with the river channel 1 through a transition section canal 3, and the transition section canal 3 is disposed along the flow direction of the river channel 1, so that the flow state of the water flow at the outlet of the tailrace channel 2 is better, and the water flow at the outlet of the tailrace channel 2 can be smoothly connected with the water flow of the main river channel. Specifically, the side walls of the transition section canal 3 include a first retaining wall 31 disposed in the river channel 1 and a second retaining wall 32 disposed on the side of the river bank where the hydropower station area is located, the end portion of the first guide wall 21 extends into the river channel 1 and is connected to the first retaining wall 31, and the second retaining wall 32 is connected to the second guide wall 22. The first retaining wall 31 is located in the river 1, can resist main river flood, and solves the problems of sediment accumulation in the tail water channel. In order to make the structure more reliable, the upstream end of the first retaining wall 31 extends to the river bank on the upstream side of the tailrace 2, so that the first guide wall 21 of the tailrace 2 is prevented from being washed by the flood. It can be understood that the tailrace 2 is of a conventional arrangement structure, and the depth of water in the canal is changed from deep to shallow (deep near the power generation plant 4 and shallow near the river channel 1), namely, the bottom plate of the tailrace 2 is provided with a longitudinal slope. And the bottom plate of the transition section canal 3 is smoothly connected with the bottom plate of the tail canal 2.
Since the second retaining wall 32 is located on the bank, in order to simplify the structure and save the engineering investment, the second retaining wall 32 may be made of slope-attached concrete located on the river bank.
