Description

Nuclear power station cold source filtering and intercepting device Technical Field The application relates to the field of cold source dirt blocking of a nuclear power station, in particular to a cold source filtering and intercepting device of the nuclear power station. Background Nuclear power generation is the process of heating water to generate steam by heat energy released by nuclear fission, and the steam drives a generator to generate electricity. In the process of generating electricity by using nuclear energy, after steam pushes a generator, the steam needs to be cooled into water and then sent into a reactor for reciprocating circulation. When the seawater is extracted, marine organisms and marine garbage in the seawater are extracted together with the seawater, so that the water quantity of cooling water is reduced due to the invasion of a large amount of dirt, the cooling effect is affected, the reactor is overheated, and the power reduction or shutdown accident is caused, and therefore, an interception device is usually arranged at the existing cold source providing place to intercept the marine organisms and the marine garbage in the seawater. The existing interception device is usually composed of a plurality of groups of different net bodies, marine organisms and ocean garbage in sea water are intercepted by installing the plurality of groups of different net bodies at a cold source water taking position, and after the net bodies intercept the marine organisms and the ocean garbage, part of the marine organisms and the ocean garbage can adhere to the net bodies to influence the entry of the sea water. Disclosure of Invention In order to reduce the probability of blocking the net body, the application provides a cold source filtering and intercepting device for a nuclear power station. The application provides a cold source filtering and intercepting device of a nuclear power station, which adopts the following technical scheme: The utility model provides a nuclear power station cold source filters intercepting device, includes the open sea guide net, blocks dirty net, has the bag to open net and hold up the net, the open sea guide net, block dirty net, have the bag to open net and hold up the net and all install on the dyke's head pier of nuclear power station water inlet, the open sea guide net, block dirty net, have the bag to open net and hold up the net and lay in proper order towards the nuclear power station from far to near on the dyke's head pier, hold up the net includes mount table, the dictyosome and anchor block, the mount table is installed in dyke's head pier, the dictyosome is installed on the mount table, the anchor block is installed in the dictyosome, and the anchor block can be dismantled in dyke's head pier bottom, the last rotation of mount table is provided with the wind-up roller, the last rotation of anchor block is provided with the guide roll, and the net body end to end links to each other the cover is established between wind-up roller and guide roll, be provided with cleaning mechanism on the guide roll, cleaning mechanism includes mounting plate, clamping lever and brush hair, the mounting plate sets firmly in the guide roll, the clamping lever slides and sets up in the mounting plate on the mounting plate, and is close to or keep away from the anchor block and is located brush hair outside the brush hair one side towards the mount table. According to the technical scheme, marine organisms and marine garbage are guided to be away from a cold source water intake of a nuclear power station through the open sea guide net, then the marine organisms and the marine garbage are longitudinally intercepted in a gradient manner through the dirt blocking net, the bag-shaped net and the bottom net, so that the probability that the marine organisms and the marine garbage enter the nuclear power station is reduced, the net bodies are connected end to form a ring shape, the net bodies are installed between the winding roller and the guide roller through sleeving, a double-layer structure is formed after the net bodies are installed, so that when a single-layer net body is damaged, the second-layer net body is used for continuing to filter and intercept, the interception efficiency is improved, meanwhile, the sleeved net body can be driven to brush the net body surface through the transmission of the net body, the marine organisms or the marine garbage adhered to the net body is removed, and therefore the blocking probability of the interception net body is reduced, the net body is clamped on the winding roller through the sliding of the clamping rod, and the net body can be wound through the rotation of the winding roller, so that the winding roller can be driven to simply, the net body is not wound, and the net body can be driven to be wound, and the winding is convenient to be overhauled or replaced. Preferably, a disassembly and assembly component is arranged between the
