Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and in particular relates to a layered water intake gate of a reservoir water intake tower. BACKGROUND

[0002] In water conservancy and hydropower engineering, there is a water temperature stratification phenomenon in the reservoir area, which will become more obvious as the water storage height rises. Taking the surface water with lower turbidity can effectively improve the comprehensive water quality of the reservoir water and reduce the water treatment cost in the later period. In order to meet the requirements of water temperature, water quality and water ecological development of the downstream of the reservoir, new reservoirs often take engineering measures to control the water intake range of the intake, and the layered water intake of the reservoir water intake tower is one of the forms.

[0003] The current reservoir water intake tower gate usually occupies a large space, such as an arc-shaped steel reservoir gate, which is not suitable for water intake towers with limited space position, and the gate opening and closing is also difficult, and the gate is poor in gradual opening. And this kind of gate needs more piers, which increases the construction cost and maintenance difficulty, especially when the gate needs to be taken out of the air opening for maintenance. CONTENT OF THE INVENTION

[0006] Among them, the water stop structure is installed on the longitudinal and transverse beam system structure based on bolts, and comprises a bottom water stop, a top water stop and a side water stop.

[0007] Among them, the bottom water stop is a strip-shaped water seal, and the top water stop and the side water stop are round head P-shaped water seals.

[0008] Among them, the gate lateral limiting device is arranged at an interval of 1cm from the gate slot.

[0009] The technical scheme provided by the present application can include the following beneficial effects:

[0010] This application provides a tiered water intake gate for a reservoir water intake tower, which is jointly manufactured using a flat steel gate, a water-stopping structure, a drive structure, and a guide structure. The gate has good gradual opening performance, low resonance under small opening conditions, reliable operation, and convenient operation. It reduces the number of management personnel and engineering investment, effectively reducing operation and management costs. At the same time, it meets the requirements of irrigation water temperature, water supply quality, and downstream water ecological development of the reservoir, and has good social and economic benefits.
