Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant safety, and in particular to a high-strength interception net for the water intake of a nuclear power plant. Background Technology

[0002] The operational status of a nuclear power plant's water intake directly affects the plant's safe operation and reliability. The water intake of a coastal nuclear power plant is affected by marine aquaculture waste and floating debris. A large amount of waste entering the pumping station through the water intake will increase the risk to the rotating filter screen, thereby threatening the unit's cooling source. Therefore, it is necessary to use an interception net to intercept the waste.

[0003] Conventional interception nets are mostly fixed with anchor blocks and buoys. Under the action of wind, waves and currents, they have weak impact resistance, which may cause marine life or floating objects to cross the net in windy and wavey environments. In order to address this technical problem, this application proposes a high-strength interception net for the intake of a nuclear power plant. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a high-strength interception net for the water intake of a nuclear power plant. Interception net one and interception net two are respectively set inside the first net body and the second net body, and then connected to the mounting frame by the first fixing frame. With the help of the reinforcing rod on the mounting frame, the strength of the mounting frame can be improved, so that even under severe conditions such as strong winds and high waves, the overall structure of the interception net can be kept stable and no floating objects will cross the net.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-strength interception net for a nuclear power plant water intake includes a floating bridge. A first fixed frame is installed at the right end of the floating bridge via an installation component. An interception net one is fixedly connected to the inner wall of the first fixed frame. A first net body is fixedly connected to the right end of the first fixed frame. A second net body is installed on the right side of the outer wall of the first net body via a connector. A second fixed frame is snapped onto the left side of the inner wall of the second net body. An interception net two is fixedly connected to the inner wall of the second fixed frame. A guide tube is inserted through the left side of the bottom end of the second net body.

[0007] Furthermore, a guardrail is fixedly connected to the top of the pontoon bridge, and multiple pontoons are provided at the bottom of the pontoon bridge.

[0008] Furthermore, the installation assembly includes multiple mounting brackets fixedly connected to the right end of the pontoon bridge, and multiple reinforcing rods fixedly connected to the left end of each mounting bracket, with the outer wall of the first fixing frame snapped into the inner wall of the mounting bracket.

[0009] Furthermore, the connector includes a first connecting frame fixedly connected to the right side of the outer wall of the first mesh body, and a second connecting frame is installed at the right end of each first connecting frame.

[0010] Furthermore, the first connecting frame and the second connecting frame are connected by bolts, and the inner wall of the second connecting frame is fixedly connected to the left side of the outer wall of the second mesh body.

[0011] Furthermore, the left end of the second fixing frame is attached to the right end of the first mesh body, and the bottom end of the second fixing frame is provided with through holes on the upper side of the guide tube.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, interception net one and interception net two are respectively set inside the first net body and the second net body, and then connected to the mounting frame by the first fixing frame. With the reinforcement rod on the mounting frame, the strength of the mounting frame can be improved, so that even under severe conditions such as strong winds and high waves, the overall structure of the interception net can be kept stable and no floating objects will cross the net.

[0014] 2. In this utility model, since the internal space of the first net body and the second net body is narrower as they get closer to the water intake, the water flow velocity inside them will gradually increase. At the same time, when the second intercepting net is installed inside the second fixed frame, it has a certain angle of inclination. Therefore, this part of the garbage will be discharged along the guide pipe under the guidance of the second intercepting net and its own gravity, so as to avoid the garbage accumulating on the surface of the second intercepting net and affecting the water intake.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 An embodiment of this utility model is provided: a high-strength interception net for a nuclear power plant water intake, including a floating bridge 1, a guardrail 2 fixedly connected to the top of the floating bridge 1, multiple pontoons 3 provided at the bottom of the floating bridge 1, a first fixed frame 6 provided at the right end of the floating bridge 1 through an installation assembly, the installation assembly including multiple mounting brackets 4 fixedly connected to the right end of the floating bridge 1, multiple reinforcing rods 5 fixedly connected to the left end of each mounting bracket 4, and the outer wall of the first fixed frame 6 being snapped into the inner wall of the mounting bracket 4;

[0023] Specifically, the guardrail 2 at the top of the floating bridge 1 provides safety for the staff. When inspecting or maintaining the interception net, the staff can rely on the guardrail 2 to prevent accidental falls into the water. The multiple buoys 3 at the bottom of the floating bridge 1 ensure the stability of the floating bridge 1 on the water surface, enabling it to withstand a certain amount of wind and wave impact, and ensuring that the entire interception net system can still work normally in complex hydrological environments.

[0024] Reference Figure 2-4 The first fixed frame 6 has an interception net 9 fixedly connected to its inner wall. The first fixed frame 6 has a first net body 7 fixedly connected to its right end. The first net body 7 has a second net body 8 set on its outer right side through a connector. The connector includes a connecting frame 10 fixedly connected to the outer right side of the first net body 7. A connecting frame 13 is installed on the right end of the connecting frame 10. The connecting frame 10 and the connecting frame 13 are connected by bolts. The inner wall of the connecting frame 13 is fixedly connected to the left side of the outer wall of the second net body 8. The second fixed frame 11 is snapped into the left side of the inner wall of the second net body 8. The second fixed frame 12 is fixedly connected to the inner wall of the second fixed frame 11. A guide tube 14 is passed through the left side of the bottom end of the second net body 8. The left end of the second fixed frame 11 is attached to the right end of the first net body 7. A through hole 15 is opened on the upper side of the guide tube 14 at the bottom end of the second fixed frame 11.

[0025] Specifically, the first fixed frame 6 contains an intercepting net 9 that can intercept organisms and large debris in the seawater. Subsequently, small organisms and debris will enter the first net body 7 and move into the second net body 8, where they will be intercepted by the second intercepting net 12 in the second fixed frame 11. Since the internal space of the first net body 7 and the second net body 8 becomes narrower closer to the water intake, the water flow velocity inside them will gradually increase and exceed the seawater flow velocity at the bottom of the guide pipe 14. At the same time, the second intercepting net 12 is installed at a certain angle inside the second fixed frame 11, so this part of the debris will be discharged along the guide pipe 14 under the guidance of the second intercepting net 12 and its own gravity, thus preventing debris from accumulating on the surface of the second intercepting net 12 and affecting water intake.

[0026] Working Principle: In practical use, the first net 9 in the first fixed frame 6 can intercept organisms and large debris in the seawater. Smaller organisms and debris will then enter the first net body 7 and move into the second net body 8, where they are intercepted by the second net 12 in the second fixed frame 11. Since the internal space of the first net body 7 and the second net body 8 becomes narrower closer to the water intake, the water flow velocity inside gradually increases, exceeding the seawater flow velocity at the bottom of the guide pipe 14. Simultaneously, the second net 12 is installed at a certain angle inside the second fixed frame 11, so this portion of debris will be discharged along the guide pipe 14 under the guidance of the second net 12 and its own gravity, preventing debris from accumulating on the surface of the second net 12 and affecting water intake. After a period of use, the staff can remove the device from the bottom of the water to clean the surface of the first net 9. Tools can also be used to connect the first frame 10 and... Remove the bolts between the connecting frames 13, take out the second fixing frame 11, and clean the surface of the second interception net 12 to ensure that the water intake is not affected. After cleaning, the first fixing frame 6 can be inserted into the mounting frame 4 and the device can be put into the sea. Then, the second net body 8 can be installed on the water intake for use. The reinforcing rod 5 set on the mounting frame 4 can improve the structural strength of the mounting frame 4, so that the first fixing frame 6 can be firmly fixed to the right end of the floating bridge 1. Even under severe conditions such as strong winds and large waves, the overall structure of the interception net can be guaranteed to be stable. The guardrail 2 at the top of the floating bridge 1 provides safety for the staff. When inspecting or maintaining the interception net, the staff can rely on the guardrail 2 to prevent accidental falls into the water. The multiple buoys 3 at the bottom of the floating bridge 1 ensure the stability of the floating bridge 1 on the water surface, enabling it to withstand a certain amount of wind and wave impact, and ensuring that the entire interception net system can still work normally in complex hydrological environments.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
