[0002] Physical interception in the open channel of nuclear power plant water intake can effectively reduce the threat of cold source blockage to water intake safety, and can also play a positive role in the protection of marine biodiversity and biological resources. More and more hydropower stations use floating trash racks as a line of defense to prevent floating waste from entering the water inlet of the power plant. The two ends of the traditional trash net are fixed on the shore anchors to form an integral combined trash rack, forming a net bag with a large front and a small back, which intercepts and collects floating objects and waste. While collecting floating objects and waste, this net bag will also catch the fish that enter at the same time. The fish cannot get out after entering, which will eventually destroy the balance of biological resources. Summary of the invention

[0013] The present invention will be further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows: Figure 1 And attached Figure 2 The embodiment of the present invention is a multi-zone modular pollution interception system for a nuclear power plant, which includes a traction rope 1, a pollution guide strip 2, and a guide rope 15. There are two guide ropes 15, and multiple groups of pollution interception units are installed between the two guide ropes 15. A front buckle 16 is provided at the front end of the guide rope 15. One end of the traction rope 1 is connected to the front buckle 16, and the other end of the traction rope 1 is connected to the shore pile; one end of the pollution guide strip 2 is connected to the rope buckle 5 through a transition rope, and the other end is connected to the pollution guide rope 7, and the other end of the pollution guide rope 7 is connected to the shore and the pollution guide pile 8.
[0014] The pollution-blocking unit includes a pollution-blocking net 3 and a hanging rope 9, wherein a net opening rope 4 is provided at the net opening of one end of the pollution-blocking net 3, the end of the net opening rope 4 is connected to the rope buckle 5 on the guide rope 15, one end of the hanging rope 9 is connected to the rope buckle 5, and the other end is connected downward to the counterweight anchor 10; a bottom rope 11 is connected to the upper part of the hanging rope 9, and the bottom rope 11 is connected to the other end of the pollution-blocking net 3; the pollution-blocking net 3 is "L" shaped when viewed from the side, the net opening rope 4 is located at the end of the vertical wall, and a sinker rope 12 is provided at the end of the horizontal arm of the net opening rope 4, and the two ends of the sinker rope 12 are connected to the corresponding bottom rope 11, and a sinker 13 is suspended on the sinker rope 12. Side nets 14 are connected between the two sides of the pollution-blocking net 3 and the bottom rope 11. The pollution-guiding strip 2 is made of foam material, and the surface of the pollution-guiding strip 2 is covered with a waterproof cloth. A float 6 is provided on the net opening rope 4, and there are multiple floats 6, which are evenly distributed on the net opening rope 4. The guide rope 15 is provided with rope buckles 5 whose number is greater than 2, and the guide floats 3 are evenly distributed on the guide rope 15 .
[0015] After adopting the above scheme, one end of the traction rope is connected to the shore pile, and the other end is connected to the guide rope. The pollution blocking unit is assembled into a module and then connected with the rope buckle. After the connection, a multi-pass pollution blocking mechanism is formed. The height of the pollution blocking net close to the traction rope is lower than the height of the pollution blocking net at the rear (the farther back the pollution blocking net is, the deeper it is). When the pollution blocking unit is assembled, the end of the net mouth rope is connected to the rope buckle on the guide rope, and the net mouth rope floats on the water surface through a float, so that the net mouth is located on the water surface.

After the connection, the pollution guide strip floats on the water surface, and a larger front and smaller rear are formed between the pollution guide strip and the pollution blocking net. The trapezoidal pollution guiding area guides the floating objects in front of both sides of the pollution blocking net, so that the floating objects on both sides flow into the pollution blocking net; the pollution blocking net is in an oblique L-shape after installation, and the two sides are connected by side nets. The hanging ropes and counterweight anchors are used, and the counterweights are sunk in the water to make the side nets vertical, preventing the collected dirt (floating objects) from flowing out from both sides of the pollution blocking net. The dirt is collected after flowing into the pollution blocking net with the water. The L-shaped pollution blocking net structure can collect the dirt. At the same time, after the fish enter the pollution blocking net, they can also swim out in front of the bottom of the net. The structure after adopting this scheme is reasonable, the use effect is good, the pollution blocking ability is strong, and the balance of biological resources can be effectively protected.
