When the diversion flow channel is opened, water flow with normal water temperature on the surface layer of the reservoir can enter the diversion flow channel through the water pipe, layered water taking of the reservoir is achieved, and therefore the water discharging temperature of water taking is improved.
Description
Technical Field
The utility model relates to a reservoir layering water intaking structure belongs to water conservancy water and electricity technical field.
Background
The medium and large-sized reservoirs have the phenomenon of water temperature stratification, and the water temperature of the surface layer of the reservoir is higher than that of the bottom layer of the reservoir between 4 months and 10 months every year. If the elevation of the water intake for power generation or irrigation is low, the low-temperature water is discharged by the power generation of the unit, a series of ecological problems are caused at the downstream of the reservoir, for example, the problems of biological extinction and the like of part of water caused by influencing the downstream fish reproduction, and the growth of crops is damaged by the low-temperature water discharged by field irrigation.
For some established projects, due to the problems of insufficient technical evaluation or supervision and the like, a layered water taking system is not configured in the reservoir construction stage, and after project delivery, low-temperature water is discharged downwards to bring adverse effects to downstream water ecology or crops. Therefore, government environmental protection or agricultural departments require that the reservoir needs to take layered water taking measures to improve the temperature of discharged water, and if not, the reservoir stops running.
At present, the stratified water taking measures of the built and under-built reservoirs in China mainly adopt a stop log door stratified water taking or multilayer water inlet water taking. The two schemes are adopted in the built reservoir for taking water in a layering mode, a cofferdam or an emptying reservoir needs to be additionally arranged in front of a water taking port, the water taking port is expanded, a corresponding gate and a corresponding hoist are additionally arranged, the project investment is huge, the construction period is long, and the operation of the reservoir is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a reservoir layered water intake structure which can avoid the great reformation of a water intake so as to solve the problem that the low-temperature water of the reservoir is discharged downwards to bring adverse effects to downstream water ecology or crops,
in order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a reservoir layering water intaking structure, includes reservoir water intaking section, is equipped with diversion flow channel in reservoir water intaking section's bottom, install the water proof gate in the reservoir water intaking section, the exit end of water pipe runs through water proof gate and diversion flow channel intercommunication, the entrance point of water pipe passes through the rope and is connected with the flotation tank.
Because the water-stop gate is used for retaining water, when the water diversion channel is opened, water flow with normal water temperature on the surface layer of the reservoir can enter the water diversion channel through the water pipe, layered water taking of the reservoir is realized, and therefore the water discharging temperature for taking water is improved.
Preferably, the water pipe includes a first steel pipe fixed to the water gate, a second steel pipe connected to the rope, and a hose communicating the first steel pipe and the second steel pipe. Therefore, the water pipes can be flexibly arranged.
Preferably, a trash rack groove is arranged in the water taking section of the reservoir, and the water isolating gate is installed in the trash rack groove.
In the scheme, the existing trash rack is removed, and the water-resisting gate is directly installed in the trash rack groove, so that reconstruction of the water taking section of the reservoir can be reduced.
Preferably, the inlet end of the water pipe is provided with a trash rack cover to intercept the dirt and prevent the dirt from entering the water pipe.
In a specific embodiment, in order to improve the flexibility of water taking from the reservoir, the buoyancy tank is provided with a lifting device, and the water pipe is connected with the lifting device through a rope. The lifting device can adjust the height of the water intake of the water pipe and ensure the water intake quality.
Preferably, the lifting device is a winch.
The utility model has the advantages that: the water intake of the steel pipe in the utility model can automatically adapt to the water level change of the reservoir, and always ensures that the water intake of the diversion flow channel comes from the surface water of the reservoir, thereby effectively improving the water intake temperature of the reservoir and reducing the adverse effect of the lower drainage on the downstream ecology and crops; and simultaneously, the utility model discloses with the trash rack replacement of original trash rack inslot for the water proof gate, can avoid carrying out big transformation to the intake, the investment is little, construction cycle is short.
