Title:
FRONT WATER INLET PRE-INTERCEPTING AND FILTERING DEVICE FOR PUMP STATION OF NUCLEAR POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2024/007525
Kind Code:
A1
Abstract:
A front water inlet pre-intercepting and filtering device for a pump station of a nuclear power plant, comprising: a frame (10), annular chains (20) being respectively provided on two sides of the frame (10), and the bottom ends of the annular chains (20) being spaced apart from the bottom of a water flow channel; mesh plates (30) continuously and fully distributed on the two annular chains (20), and the two sides of each mesh plate (30) being fixedly connected the two annular chains (20), respectively; and a driving device comprising a motor (110), a main shaft (116) mounted on the frame (10) by means of bearing seats (114), and two chainwheels (118) provided on the main shaft (116), the motor (110) driving the main shaft (116) to rotate, and driving, by means of the engagement of the two chainwheels (118) and the two annular chains (20), the two annular chains (20) and the mesh plates (30) fixedly connected to the two annular chains (20) to perform reciprocating motion. In the front water inlet pre-intercepting and filtering device for a pump station of a nuclear power plant, the bottom ends of the annular chains (20) and the bottom ends of the mesh plates (30) are all spaced apart from the bottom of the water flow channel, thereby guaranteeing a safe water passing channel under an extreme working condition that all meshes (302) are blocked, performing non-full-section water passing pre-interception, increasing the flow passing section, effectively pre-intercepting and filtering marine organisms, and guaranteeing safe and stable operation of the unit.
