[0025] The water intake system proposed in the application embodiments will be further described below with reference to the accompanying drawings.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of the water intake system provided in an embodiment of this application. As shown in the figure, the water intake system 100 includes an open water intake channel 10, a protective dike 20, and multiple water intake units 30 installed in the open water intake channel 10.

[0027] Both the water intake channel 10 and the protective dike 20 are located on the seabed and are higher than the sea level. The water intake channel 10 extends from the land towards the sea.

[0028] The water intake channel 10 includes a first inlet located away from the land and perpendicular to the sea level. A protective dike 20 is located outside the first inlet. The protective dike 20 and the first side of the water intake channel 10 form a second inlet. The protective dike 20 and the second side of the water intake channel 10 form a third inlet. The first side and the second side of the water intake channel 10 are two sides of the water intake channel 10 that are set opposite to each other.

[0029] Each of the multiple water intake units 30 includes an inlet and an outlet. The inlet is connected to a first inlet via a first pipe, and the outlet is connected to the water source equipment to be input via a second pipe.

[0030] It should be understood that the aforementioned water intake system 100 can be applied to nuclear power plants. Specifically, the aforementioned water intake channel 10 must be located in a position with sufficient water depth and favorable conditions such as shoreline stability, geological conditions, and tidal levels to meet the water intake requirements of the water supply system. Furthermore, the water intake channel 10 extends from the land towards the sea, and its length and width should also meet the water intake requirements of the water supply system.

[0031] The water intake channel 10 has a first inlet at its end facing the center of the sea area, through which seawater enters the channel. A protective dike 20 is installed outside the first inlet to block debris, reducing the amount of debris entering the water intake channel 10 through the first inlet. A second and third inlet are formed on the opposite sides of the protective dike 20 and the water intake channel 10, respectively, allowing seawater to enter through the second and third inlets before entering the water intake channel 10 through the first inlet. In this way, debris is blocked outside the protective dike 20, and seawater enters the water intake channel 10 through the second and third inlets and then through the first inlet, thus improving the quality of the water source within the water intake channel 10.

[0032] It should be understood that the distance between the protective dike 20 located outside the first inlet and the end of the water intake channel 10 where the first inlet is located should also meet the water intake width requirements of the water intake channel 10. For example, the width of the first inlet is equal to the distance between the protective dike 20 and the end of the first inlet.

[0033] The protective dike 20 can be constructed using a concrete structure. In practice, the protective dike 20 can be constructed in the same way as the water intake channel 10. In an optional embodiment, firstly, the area where the water intake channel 10 and the protective dike 20 are to be constructed is isolated from the seawater using a protective structure. Then, the water intake channel 10 is constructed extending from the land towards the sea, and a temporary dike is set at the port of the water intake channel 10, and the protective dike 20 is constructed. Afterward, the temporary dike is dismantled, ultimately forming a water intake structure with the water intake channel 10 and the protective dike 20.

[0034] It should be understood that the angle and direction of the breakwater can be flexibly adjusted according to the main wave direction and the main wind direction of the sea area. That is, the extension direction of the breakwater 20 is set at a preset angle with the extension direction of the water intake channel 10, wherein the preset angle is greater than 0 degrees and less than or equal to 90 degrees.

[0035] In an alternative implementation, such as Figure 2As shown, the extension direction of the water intake channel 10 can be set perpendicular to the direction of the tide movement. In this way, during high tide, seawater can enter the water intake channel 10 from the third inlet and through the first inlet, and during low tide, seawater can enter the water intake channel 10 from the second inlet and through the first inlet.

[0036] Multiple water intake units 30 are installed within the water intake channel 10. Each water intake unit 30 may include a circulating water pump. Each water intake unit 30 has an inlet and an outlet. The inlet is connected to a first inlet via a first pipe, and the outlet is connected to the equipment to which the water source is to be input via a second pipe. Seawater, blocked by the protective dike 20, enters the water intake channel 10 through the second and third inlets, and then through the first inlet. This improves the quality of the water source pumped from the first inlet and delivered to the equipment.

[0037] The water intake requirements of the water system may be related to the maximum water intake capacity of the multiple water intake units 30. In an optional embodiment, when the maximum water intake capacity of two water intake units 30 can meet the water intake requirements of the water system, the two water intake units 30 are installed in the water intake open channel to draw water as the water source.

[0038] In this embodiment of the application, by setting a protective dike 20 outside the first inlet of the water intake channel 10, the protective dike 20 can prevent debris in the sea area from entering the water intake channel 10. When the water intake unit 30 set in the water intake channel 10 takes water, the quality of the water source can be improved.

[0039] Optionally, at least one partition wall is provided in the water intake channel 10. The partition wall is aligned with the direction of the water intake channel 10. The partition wall divides the water intake channel 10 into at least two sub-channels. The first inlet is connected to either sub-channel.

[0040] At least two of the multiple water intake units 30 are respectively installed in the first sub-ditch and the second sub-ditch of the at least two sub-ditches.

[0041] According to the water intake requirements of the water system, a partition wall can be set in the water intake channel 10. The partition wall should be in the same direction as the water intake channel 10. The partition wall divides the water intake channel 10 into sub-channels, and each sub-channel is connected to the first inlet.

[0042] In an optional implementation, when the maximum water intake capacity of the four water intake units 30 is sufficient to meet the water intake requirements of the water system, a partition wall can be installed in the water intake channel 10 to divide the water intake channel 10 into two sub-channels. The four water intake units 30 are evenly distributed in the two sub-channels to draw water from the sub-channels as the water intake source.

[0043] In another optional implementation, the number of water intake units 30 is six, and the number of partition walls is two. The two partition walls divide the water intake channel 10 into three sub-channels. Each sub-channel is equipped with two water intake units 30, and each water intake unit 30 draws water from the sub-channel as its water source.

[0044] In this way, by setting up multiple water intake units 30 and distributing them evenly for water intake, the water intake efficiency can be improved.

[0045] Optionally, the protective dike 20 is a receiving structure with an opening, and the first inlet is located within the receiving structure.

[0046] In this embodiment of the application, by setting the protective dike 20 as a accommodating structure that encloses the first inlet to prevent debris from entering the first inlet, the quality of the water source entering the water intake channel 10 through the first inlet can be improved.

[0047] Optionally, the protective dike 20 includes a first region, a second region, and a third region. The first region is parallel to the horizontal plane where the first inlet is located. The second region and the third region are disposed opposite each other on both sides of the first region. The second region extends from the first region toward a first side close to the water intake channel 10, and the third region extends from the first region toward a second side close to the water intake channel 10.

[0048] The first region of the aforementioned protective dike 20 is parallel to the plane where the first inlet of the water intake channel 10 is located, while the second and third regions of the protective dike 20 are arranged opposite to each other on both sides of the first region to form a surrounding structure with openings.

[0049] In practice, the extension end of the second region forms a second inlet with the water intake channel 10, and the extension end of the third region forms a third inlet with the water intake channel 10. Seawater can enter from the second and third inlets, pass through the first inlet, and continue into the water intake channel 10.

[0050] In an optional embodiment, both the second region and the third region are semi-circular structures. The two semi-circular structures and the first region can intercept debris in the seawater on the outside. Seawater then enters the surrounding structure formed by the first region and the two semi-circular structures through the second and third inlets, and then enters the water intake channel 10 through the first inlet.

[0051] In another alternative embodiment, the second region and the third region may also be structures arranged parallel to the extension direction of the water intake channel 10.

[0052] Optionally, the widths of the first entrance, the second entrance, and the third entrance are all the same.

[0053] In this embodiment, by setting the widths of the first inlet, the second inlet, and the third inlet to be consistent, the flow velocity of seawater entering each inlet is made more uniform, which can also improve the quality of the water entering the water intake channel 10 to a certain extent.

[0054] Optionally, the widths of the second entrance and the third entrance are equal to the vertical distance from the first entrance to the first region.

[0055] Optionally, the water intake channel 10 is located within the first region in the vertical projection area of ​​the protective dike 20.

[0056] In this embodiment of the application, by setting the vertical projection area of ​​the water intake channel 10 in the protective dike 20 to be located in the first area, it is ensured that the protective dike 20 can completely surround the first inlet of the water intake channel 10, so as to intercept seawater debris entering the second and third inlets on the outside, thereby improving the quality of the water source.

[0057] Optionally, the vertical projection area of ​​the second region on the first surface of the water intake channel 10 partially overlaps with the first surface of the water intake channel 10, and the vertical projection area of ​​the third region on the second surface of the water intake channel 10 partially overlaps with the second surface of the water intake channel 10.

[0058] That is, the extension end of the second region exceeds the horizontal plane of the first inlet of the water intake channel 10, and the extension end of the third region also exceeds the horizontal plane of the first inlet of the water intake channel 10. In this way, the interception efficiency of the protective dike 20 is improved, and further, the quality of the water source entering the water intake channel 10 can be improved.

[0059] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
