The cold water intake system (RRI) of a nuclear power plant usually includes two independent safety series, a common loop, and a common part between the two units. The number of working units and the number of pumps in the system depend on the operating conditions and the required heat. When operating at power, the main users are the main pump and the non-regenerative heat exchanger; when cooling the reactor, the main user is the waste heat removal system;

When a marine biological disaster breaks out, the three pollution interception nets are used simultaneously and in conjunction with the trawl net, which can quickly and effectively remove marine life and ensure the safety of water intake for the nuclear power plant; at the same time, the pollution interception net of the utility model has a strong ability to resist wind and waves;

[0004] Announcement No.: CN209741784U, proposes a technical solution for a nuclear power plant water intake water area cleaning system, which uses a dirt baffle obliquely inserted into the water to intercept garbage and debris in the water body on the water side of the water inlet, ensuring one-sided interception and one-sided cleaning of the dirt baffle, and at the same time the dirt baffle can be flipped over so that maintenance personnel can perform horizontal operations when they need to clean the dirt baffle; the cleaning walkway can ensure that maintenance personnel can perform convenient and efficient inspection and maintenance on specific parts of the nuclear power plant water intake water area cleaning system; a ship passage is set on the nuclear power plant water intake water area cleaning system, and the dirt baffle and cleaning walkway can be opened when a ship needs to pass.

The rotation of the electric crossbeam can synchronously control the vertical roller to move. At the same time, the movable column is controlled to rotate by the motor, thereby synchronously driving the No. 1 bevel gear to rotate. When the No. 1 bevel gear rotates, the No. 1 bevel gear can control the rotation of the No. 2 bevel gear through the tooth pattern.

[0037] 2. When the work is finished, the electric push rod is controlled to work, and the electric push rod can push the control plate to move backward. When the control plate moves, the control plate can push the rotating connecting plate to move. At this time, the movement of the rotating connecting plate can push the sliding plate to move to the left. When the sliding plate moves, the sliding plate can guide the pulling belt to move. At this time, the pulling belt can pull the limiting baffle forward, thereby unlocking the impurity biological collection box, making it convenient to pull out the impurity biological collection box and clean the impurity biological collection box;

[0038] 3. The movement of the limiting baffle can synchronously push the matching plate forward. At this time, the movement of the matching plate can pull the movable belt to move. The movable belt can be unwound from the outer wall of the eccentric rotating wheel, thereby controlling the eccentric rotating wheel to rotate. When the eccentric rotating wheel rotates, the eccentric rotating wheel can contact the movable support frame, thereby pushing the movable support frame to move to the left. At this time, the movable support frame can drive the guide rack to engage with the matching gear, and the contact pressure plate moves to the top of the movable door, while controlling the servo motor to work. The output shaft of the servo motor can control the guide rack to descend through the matching gear. When the guide rack descends, the guide rack drives the contact pressure plate to descend. At this time, the contact pressure plate contacts the top of the movable door, controlling the movable door to descend and close, thereby controlling the flow of seawater and facilitating work;

[0039] When the present invention is controlling a supporting pier, when seawater enters the open water intake channel, it is initially filtered through the seawater filter net, and at the same time, the electric crossbeam, vertical roller, disc and vertical plate cooperate to entangle the flocculent impurities, and at the same time, the impurity organisms in the seawater are obliquely guided into the impurity organism collection box to prevent blockage and rupture. At the same time, after stopping work, the electric push rod cooperates with the servo motor to facilitate the extraction and cleaning of the impurity organism collection box to prevent long-term accumulation of impurities and affect the work.
