Automatic remove equipment for disaster blooming marine organisms of sea water intake channel belongs to the field of marine environmental engineering and equipment. The equipment comprises a cod-end of collecting net, a saw blade at the end of net, a fixation and support system, a submersible spiral pump, a transport pipe system, a separating system on coast and floats. The equipment collects the disaster blooming marine organisms in the sea water channel into the bottom of a cod-end of collecting net, and cuts and decomposes the collected disaster blooming marine organisms by using a saw blade at the end of net under the combined action of the water flow power and the suction pressure of a submersible spiral pump. Fragments after cutting are sucked by the submersible spiral pump and delivered to a coast, and are subjected to solid-liquid separation by a separating system on coast and then are centrally disposed. The equipment is sturdy and durable and can resist corrosion of the sea water environment; and the equipment can efficiently collect and remove the disaster blooming marine organisms in the industrial sea water intake channel automatically, thereby saving labor cost, ensuring normal operation of the industrial system and increasing production benefits.

The present invention relates to a method for repairing an intake for a storage dam, which comprises; constructing a cabin for controlling sediment, formed by modular rings that are 12 m in diameter and 3 m high, to allow the demolition of the old intake without draining the area; prefabricating elements for extending the new intake in situ by means of metallic formwork for setting the modular elements which are subsequently steam-cured and transferred to a final location by means of a barge and cranes. The final assembly is carried out using divers and cabin equipment, such as lighting, closed-circuit cameras, monitoring, emergency stairs and an elevator or service elevator, ensuring a reduction in the time and cost of repairing an intake in storage dams.

A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portionseach communicating with flow from one of the flow modifiers. The device can include one or more plates disposed adjacent one another within the internal hollow with a peripheral edge attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or one or more of the plates can define openings therein allowing passage of at least some fluid therethrough.

A screen intake apparatus for a water intake system uses a cleaning system to clean one or more screen intakes. To clean debris from a screen, pipes in the interior of the screen receive pumped liquid (e.g., water or incompressible liquid) from a pump. Outlets, such as apertures or nozzles, on the pipes then direct the pumped liquid into the interior of the screen. One or more valves can vary, agitate, or pulse the flow of pumped fluid and/or can selectively deliver the pumped liquid to the pipes to remove collected debris from the exterior of the screen. A heater of the system can also heat the pumped liquid for delivery to the pipes to remove or prevent ice formation on the screen.

A sea water intake system comprising a main sea water intake pipe, one end of the sea water intake pipe being provided with a centrifugal chamber, the chamber having at least one tangential inlet for entry of sea water to cause rotation of the sea water in the chamber. The other end of the intake pipe terminates in a sump, the sump having a water level lower than that of sea level and having a pump to transport sea water from the sump through a delivery pipe to a treatment plant. A central region of the centrifugal chamber is in fluid communication with a substantially vertical airlift pipe having an air inlet at, or close, to the chamber and a water exit remote from the chamber.
