Automatic layered water taking system

Abstract

The invention discloses an automatic layered water taking system. The automatic layered water taking system comprises roller blind curtains, water-permeable hanging cloths and a layered water taking tower. Electromagnetic blocks are correspondingly arranged at the two sides and the bottom of side blocks and fence blocks of the upstream face of the water taking tower. Winches, rollers and roller supports are mounted on the top of the water taking tower. The hanging cloths are wound around reels of the winches. The hanging cloths are hung on the upstream face of the water taking tower through the rollers. The hanging cloths are connected with the roller blind curtains through cylinders. Counterweight strips are fixedly bonded to the lower sides of the roller blind curtains. An iron flexiblematerial is attached to the two sides and the bottom of each roller blind curtain. The relative height of the electromagnetic block and flexible material arrangement positions relative to the portionbetween the bottoms of water channels is the same as the water taking elevation preset by a user. The electromagnetic blocks are independently communicated with a power source. The automatic layered water taking system has the beneficial effects that the water isolation range of the roller blind curtains is lowered to be below the water taking elevation preset by the user through the windable roller blind curtains which is driven to rotated under the dead weight of the cylinders, and only low-temperature water is blocked, so that the high-temperature water above the water taking elevation is obtained, and the purpose of layered water taking is achieved.

Description

technical field [0001] The invention specifically relates to the technical field of hydropower and water conservancy engineering, in particular to an automatic layered water intake system. Background technique [0002] In water conservancy and hydropower projects, the water intake tower is an important building of the water diversion power generation system, which is related to the operation and implementation of the water diversion power generation system and ecological water intake, and is also an important part of environmental protection. After the formation of large and medium-sized reservoirs, the water temperature in the reservoir area will be stratified, and the discharge of the water temperature in the middle and lower layers of the reservoir area will affect the water temperature distribution in the downstream river section, thus causing adverse effects on irrigation and aquatic organisms. At present, the water intake towers of domestic hydropower stations adopt th...

After the formation of large and medium-sized reservoirs, the water temperature in the reservoir area will be stratified, and the discharge of the water temperature in the middle and lower layers of the reservoir area will affect the water temperature distribution in the downstream river section, thus causing adverse effects on irrigation and aquatic organisms

At present, the water intake towers of domestic hydropower stations adopt the steel structure multi-section door leaf stacking beam door structure. The steel structure stacking beam door is a combination of multi-section door leaves. Hoisting section by section, the amount of steel used is large, and the investment is high
