Description
Technical Field
The utility model belongs to the technical field of hydraulic engineering, and particularly relates to a pontoon type water taking device suitable for taking water from the surface layer of a medium-small reservoir.
Background
Reservoir irrigation and downstream ecological water generally need to be taken to be high in temperature and clean, and the existing reservoir water taking mainly adopts a layered water intake tower or a deep water intake to meet the water taking requirement. However, the layered water intake tower usually only can take the water at the uppermost layer of the reservoir, and the water in the upper layer has higher temperature but usually has more floaters, so that the floaters are easy to block the water intake and the water delivery pipe network, and can pollute farmlands; the deep water intake can not adapt to the change of the water level of the reservoir, and meanwhile, the water intake temperature is too low due to the large water depth when the water level of the reservoir is high, so that the requirements of downstream irrigation and ecological water can not be met. The layered water intake tower or the deep water intake has the larger common problem that the water intake building is usually higher, the control lock chamber is composed of a concrete structure, the requirement on the basic geological condition is higher, and a large amount of manpower and material resources are required to be consumed.
Disclosure of Invention
In order to provide a device capable of stably taking surface layer reservoir water about 1 meter below the water surface in response to reservoir water level change, not only meeting the requirements of irrigation and ecological water on temperature, but also avoiding the water intake from being blocked by reservoir water surface floaters and polluting downstream crops, the utility model provides a pontoon type water taking device suitable for taking water from the surface layer of a medium-sized and small-sized reservoir.
The floating pontoon type water taking device suitable for water taking from the surface layer of a medium and small-sized reservoir is arranged at the water inlet of a water delivery tunnel of the reservoir and is characterized by comprising a water delivery pipe, a spherical compensation joint, a water taking pipe, a floating ball, a sling, an anchor pier and a traction rope, wherein the water delivery pipe is buried at the water inlet of the water delivery tunnel of the reservoir, two ends of the water delivery pipe are respectively connected with the water delivery tunnel of the reservoir and one end of the spherical compensation joint, the other end of the spherical compensation joint is connected with the bottom end of the water taking pipe, the top end of the water taking pipe is connected with the floating ball through the sling, the length of the sling is 1m, and meanwhile, the floating ball is connected with the anchor pier fixed at the bottom of the reservoir through the traction rope, and a trash rack is arranged at the pipe orifice of the water taking pipe.
Further, the anchor pier is made by concrete casting.
The utility model has the beneficial effects that: firstly, the water intake is ensured to be stabilized at the position of 1 meter under water by the traction of the floating ball and the gravity action of the water intake pipe so as to ensure that the water intake temperature of the reservoir is ensured. Secondly, the spherical compensation joint can ensure that the water intake pipe rotates within a range of 10 degrees by taking the root as an axis so as to adapt to reservoir water level change, and meanwhile, ensure smooth connection of the water intake pipe and the water delivery pipe. Finally, the traction rope and the anchor pier can ensure the stability of the floating ball on the water surface, so that the floating ball cannot be blown away by wind and waves, and meanwhile, the stress of the water intake pipe and the spherical compensation joint can be reduced. Compared with the traditional method, the method solves the influence of reservoir water change on irrigation and downstream ecological water quality, reduces the construction engineering quantity and reduces the requirement of a water inlet building on an underwater foundation. And the water intake depth control method is more flexible and convenient than the traditional layered water intake tower or deep water intake.
