Description

Technical Field

[0001] The present invention relates to the technical field of trash interception, and specifically to a trash interception system used in the nuclear power water intake channel. Background Art

[0002] The nuclear power system refers to a system that uses nuclear energy to generate electricity, mainly including a nuclear reactor, a steam generator, a steam turbine, a generator, and related auxiliary systems. A nuclear power plant conducts nuclear fission or nuclear fusion reactions through nuclear fuel (such as uranium) in the nuclear reactor to generate a large amount of heat energy. This heat energy is used to heat water to generate steam, and the steam then drives the steam turbine to rotate, thereby driving the generator to generate electricity. The whole process is similar to that of a thermal power plant, but nuclear energy is used instead of fossil fuels. In the nuclear power system, its water intake channel (or cooling water intake channel) is a key component of the nuclear power plant's cooling system, mainly used to transport seawater or fresh water to cool the reactor or auxiliary equipment. Since the water may carry a large number of organisms (such as shellfish, algae, fish, aquatic plants, etc.), the overgrowth or accumulation of these organisms may cause pipeline blockage, equipment corrosion, or system efficiency decline. Therefore, it is necessary to set up a trash interception system at the water intake channel to filter impurities (including but not limited to a large number of organisms) in the water. However, in the existing trash interception systems, it is difficult to collect the intercepted impurities, which has certain limitations. Generally, personnel drive a boat to the trash interception system to salvage the intercepted impurities, resulting in a large labor intensity.

[0059] A number of frames 20 are installed between the two groups of fixed plates 10 through connection components, so as to facilitate the disassembly and assembly of the frames 20 by personnel.

[0060] The connection components include: a square block 30, a groove 31, a positioning hole 32, a convex block 33, a positioning rod 34, a driving plate 35, and a spring 36;

[0061] Square blocks 30 are fixedly installed on the right side of the frame 20 and the right side of one group of fixed plates 10. The groove 31 is opened in the square block 30, and the groove 31 penetrates through the square block 30.

The spring 36 is sleeved on the positioning rod 34, and both ends of the spring 36 are fixedly connected to the driving plate 35 and the square block 30 respectively.

[0062] In specific use, the operation steps of those skilled in the art are as follows:

[0063] Step 1: Through the driving plate 35, one end of the positioning rod 34 is located in the square block 30. At this time, the spring 36 will deform. Then, the convex block 33 is inserted into the groove 31. After insertion, one end of the positioning rod 34 will pass through the through hole and be inserted into the positioning hole 32 through the spring 36. Thus, the frame 20 can be fixed between the two groups of fixed plates 10;

[0064] Step 2: When water passes through the stainless steel filter screen 21, impurities in the water (including but not limited to a large number of organisms) will be filtered. Since the shape of the stainless steel filter screen 21 is set as a net bag shape, the filtered impurities will flow into the riser 41 through the diversion pipe 40;

[0065] Step 3: When there is a certain amount of impurities in the riser 41, the first servo motor 54 will be used to rotate the circular plate 51 until the circular plate 51 blocks the diversion pipe 40 to prevent impurities from flowing into the riser 41;

[0066] Step 4: The second servo motor 66 is used to rotate the spool 64. When the spool 64 rotates, the rope 67 will be released or wound (the rope 67 located above is wound, and the rope 67 located below is released). At this time, the lifting block 68 will drive the impurities to rise so as to bring the impurities into the collection box 42 for collection. After that, the lifting block 68 can be restored to its original position. Among them, the collected impurities can be taken away by personnel for operations such as crushing.

[0067] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention.
