[0002] At present, most of the steam turbine units of power plants are condensing type. Steam becomes 25-45℃ exhaust steam after doing work through all impellers of steam turbine. The exhaust steam is cooled by circulating water (cooling water) to condense into water to realize the recycling of water in the exhaust steam. After the heat exchange is completed, the cooling water is usually discharged into the adjacent sea to become cooling warm water.

The direct discharge method can cause a large range of sea surface temperature rise, greatly affect the marine environment, and affect the breeding and growth of fishery. The other two methods are to discharge the cooling water to the deep sea to speed up the heat exchange with the deep sea water to avoid affecting the sea temperature in a large range, and to discharge the cooling water after treatment by the cooling water tower. Although the cooling water can be well treated, the cost of these two methods is extremely high. In view of this, the related technical personnel urgently need to solve a cooling water discharge method with low cost. SUMMARY

[0036] Coastal power plants, mostly employing condensing steam turbine units, typically discharge cooling water directly into the sea after heat exchange. However, direct discharge raises sea surface temperatures, impacting the marine environment, fisheries, and aquaculture. This disclosure provides a cooling water discharge structure for coastal power plants. The structure includes foundation piles and a concrete water-retaining structure. The lower ends of the foundation piles are embedded in the seabed, providing a foundation for the concrete water-retaining structure. The concrete water-retaining structure extends a certain distance perpendicular to the cooling water discharge direction and is fixedly connected to the upper end of the foundation piles, forming a drainage outlet between the bottom of the concrete water-retaining structure and the seabed. During discharge, the cooling water exits through this outlet, limiting its depth into the ocean to between the bottom of the concrete water-retaining structure and the seabed, thus preventing a rise in sea surface temperatures due to the discharge of cooling water.

[0037] For the purpose of facilitating understanding, the following will refer to the accompanying drawings in detail Figures 1 to 7 to explain the coastal power plant cooling water discharge structure of the present disclosure in conjunction with the embodiments.

[0038] In one embodiment of the present disclosure, referring to Figure 1 , the coastal power plant cooling water discharge structure comprises a foundation pile 1 and a concrete water retaining structure 2. The lower end of the foundation pile 1 is embedded in the seabed to be fixed, providing a mounting base for the concrete water retaining structure 2. The foundation pile 1 can be a concrete pile, which can be poured in a pre-set steel casing in the seabed to improve the stability of the concrete pile and make the overall cooling water discharge structure more stable. Of course, in other embodiments, the foundation pile 1 can also be other pile bodies that can be installed on the seabed, as long as they have good stability and can provide a mounting base for the concrete water retaining structure 2, which is not limited by the present disclosure.

[0039] The concrete water retaining structure 2 is made of concrete material. The concrete can be adjusted by formula to make the entire concrete water retaining structure 2 have good corrosion resistance, and the concrete also has strong plasticity to adapt to the needs of most environments and locations. Moreover, the cost of concrete is relatively low, which can save a lot of resources for users. In this embodiment, the concrete water retaining structure 2 extends along the direction perpendicular to the discharge direction 5 of the cooling water and is spaced apart from the seabed by a certain distance, and is fixedly connected with the upper end of the foundation pile 1. The space between the bottom end of the concrete water retaining structure 2 and the seabed forms a drain port 3, so that the cooling water above the drain port 3 is blocked by the concrete water retaining structure 2 when discharging, and can only be discharged from the drain port 3, thereby limiting the depth of the cooling water discharged into the ocean.

[0040] In one embodiment of the present disclosure, referring to Figure 1 and Figure 2 , since the overall length of the part where the cooling water discharge structure needs to be installed is relatively long, in order to facilitate the installation of the cooling water discharge structure. When installing, the cooling water discharge structure is divided into multiple sections for installation. In this embodiment, the cooling water discharge structure is divided into multiple discharge units 100, the foundation pile 1 is divided into multiple first foundation piles 11 arranged along the direction perpendicular to the discharge direction 5 of the cooling water, and the concrete water retaining structure 2 is divided into multiple water retaining units 20 along its extending direction. Referring to Figure 1 , in this embodiment, the cooling water discharge structure includes a horizontally extending part and a vertically extending part, and their extending directions are respectively perpendicular to the discharge direction 5 of the cooling water. Of course, in other embodiments, the cooling water discharge structure can also be arc-shaped, or other shapes, and the discharge direction 5 of the cooling water can also be approximately perpendicular to the extending direction of the first foundation pile 11, which can be determined according to the actual situation, and the present disclosure does not limit it.

[0041] The discharge unit 100 comprises two first base piles 11 and a water blocking unit 20. The water blocking unit 20 is located between the two first base piles 11, and a space between the bottom end of the water blocking unit 20 and the seabed forms a water discharge port 3. The discharge unit 100 can block and discharge cooling water at different heights. Of course, in other embodiments, the discharge unit 100 can comprise other numbers of first base piles 11 and water blocking units 20, which can be determined according to actual installation conditions, such as the geographical location of the seabed, the length of the entire cooling water discharge structure, etc., and the present disclosure does not limit this.

[0042] In an embodiment of the present disclosure, referring to Figure 3 and Figure 4 , the water blocking unit 20 comprises a connecting plate 21 and a first water blocking plate 22. The connecting plate 21 is located at the upper part of the water blocking unit 20 and is used to fixedly connect the water blocking unit 20 with the upper end of the first base pile 11. In this embodiment, the connecting plate 21 is in the shape of a flat plate, and steel bars are arranged at both ends of the connecting plate 21 in the extension direction of the concrete water blocking structure 2, so as to facilitate the pouring connection between adjacent water blocking units 20 to form the concrete water blocking structure 2. Of course, in other embodiments, the connecting plate 21 can also be in other shapes, such as an arc-shaped plate, and other connecting devices can also be arranged thereon for connection with adjacent water blocking units 20, which can be determined according to actual conditions, and the present disclosure does not limit this. The first water blocking plate 22 is consistent with the shape of the connecting plate 21 and is also in the shape of a flat plate. The first water blocking plate 22 is located between and tightly attached to the two first base piles 11, so as to prevent cooling water from flowing into the shallow seawater through the gap between the two first base piles 11. The upper edge of the first water blocking plate 22 is fixedly connected with the connecting plate 21, so as to be fixedly connected with the first base pile 11 through the connecting plate 21. The lower edge of the first water blocking plate 22 extends towards the seabed to form the water discharge port 3, so that the cooling water can be discharged into the deep ocean through the water discharge port 3.

[0043] As known from the above embodiment, the first water blocking plate 22 and the first base pile 11 are only tightly attached to each other and are not connected through other devices. However, when the cooling water is discharged, the speed of the water flow is sometimes too large, or after a long time of impact, the first water blocking plate 22 is subjected to a large or long-time stress, and then the first water blocking plate 22 can be offset or deformed. In order to solve the above problem, in an embodiment of the present disclosure, referring to Figure 5 and Figure 7The two adjacent water retaining units 20 are also fastened together by fasteners 24. The first water retaining plate 22 is provided with connecting holes 220, and the two adjacent first water retaining plates 22 are connected by the fasteners 24 which pass through the connecting holes 220 of the first water retaining plates 22 to fasten the two adjacent first water retaining plates 22 and the first pile 11 therebetween, so that the first water retaining plate 22 can be supported by the first pile 11 when it is impacted by the water flow.

[0044] The fastener 24 includes a first fastener 240 and a second fastener 241. When connected, one end of the first fastener 240 and the second fastener 241 respectively passes through the connecting holes 220 of the two adjacent first water retaining plates 22, and then the first fastener 240 and the second fastener 241 on both sides of the first water retaining plate 22 are tightened towards the first pile 11. After tightening, the same end of the first fastener 240 and the second fastener 241 is fastened by a bolt 25 to complete the connection, so that the adjacent first water retaining plates 22 can be more stably connected with the first pile 11 under the action of the fastener 24. See Figure 5 In the embodiment, the connecting holes 220 are located on both sides of the first water retaining plate 22, and two are provided on the upper end and the lower end respectively. This arrangement facilitates the connection of the fastener 24, and the arrangement of the connecting holes 220 up and down can also make the fastening effect better. Of course, in other embodiments, the connecting holes 220 on the first water retaining plate 22 can also be arranged at other positions, and the number thereof can be more or less, which can be determined according to the actual situation, and the present disclosure does not limit this.

[0045] In one embodiment of the present disclosure, see Figure 3 and Figure 4 The water retaining unit 20 also includes a second water retaining plate 23. The second water retaining plate 23 is in the form of a flat plate as a whole, and its lower edge is fixedly connected with the upper edge of the connecting plate 21, and the other end extends away from the seabed and is symmetrically distributed with the first water retaining plate 22 along the connecting plate 21. The second water retaining plate 23 and the connecting plate 21 can be connected by pouring concrete, and of course other connection methods can also be used, which can be determined according to the actual situation, and the present disclosure does not limit this. When the seawater on the side of the cooling water discharge structure towards the cooling water rises due to weather or other reasons and is higher than the height of the connecting plate 21, the seawater can be blocked by the second water retaining plate 23 to prevent the cooling water therein from directly discharging to the seawater on the other side, thereby preventing the temperature of the surface layer of the seawater from rising.

[0046] In one embodiment of the present disclosure, see Figure 2 and Figure 3The first pile 11 and the second pile 12 are fixedly connected with the first pile 11, and through the second pile 12, the impact force of the water flow on the first pile 11 can be shared when the concrete water retaining structure 2 on the first pile 11 is impacted by seawater or when the cooling water is discharged, so as to improve the stability and service life of the first pile 11. In the embodiment, the discharge unit 100 includes two second piles 12 arranged opposite to the first pile 11, and the first piles 11 and the second piles 12 of different discharge units 100 are fixedly connected together, thereby forming the entire cooling water discharge structure. Of course, in other embodiments, the number of the second piles 12 in the discharge unit 100 can also be other numbers, as long as the number is consistent with that of the first piles 11, and the specific number can be determined according to actual conditions, and the disclosure does not limit this.

[0047] In an embodiment of the disclosure, when the coastal power plant cooling water discharge structure of the disclosure is installed, the installation is first considered according to the situation of the revetment and the seabed, as shown in Figure 1 The first pile 11 and the concrete water retaining structure 2 include a horizontally extending part and a vertically extending part. Of course, in other embodiments, the extension direction of the first pile 11 and the concrete water retaining structure 2 can also be circular arc-shaped or other shapes, and the specific shape can be determined according to actual conditions, and the disclosure does not limit this.

[0048] When the cooling water discharge structure is installed, the installation of the first discharge unit 100 is first performed. During the installation process, the pouring of the two first piles 11 and the second piles 12 is performed, and in the embodiment, the concrete piles are used. After the pouring of the first piles 11 and the second piles 12 is completed, the water retaining unit 20 is placed between the two first piles 11, and the water retaining unit 20 can be temporarily placed on the upper end of the first pile 11 through the connecting plate 21. After the water retaining unit 20 is placed, the horizontal beam 41 is poured between the opposite first piles 11 and the second piles 12 through the method of pouring concrete, so as to fixedly connect the first piles 11 and the second piles 12 together. During the pouring process of the horizontal beam 41, the pouring between the connecting plate 21 and the first pile 11 is also simultaneously performed, so that the connecting plate 21 can be fixedly connected with the first pile 11. After the connecting plate 21 is connected with the first pile 11, the pouring of the second water retaining plate 23 is continued, the second water retaining plate 23 is poured with the connecting plate 21, so that the two are fixedly connected, and the installation of the first discharge unit 100 is finally completed. In the embodiment, as shown in Figure 2The deformation joint 410 is arranged at the middle of the cross beam 41. When the cross beam 41 is subjected to a large stress, the deformation joint 410 can provide a space for deformation, so that the cross beam 41 will not be directly broken, thereby increasing the safety of the entire cooling water discharge structure. Of course, in other embodiments, the deformation joint 410 can be arranged on each cross beam 41, or other similar spaces for deformation can be arranged, which are not limited in the present disclosure.

[0049] When the first discharge monomer 100 is installed, the next discharge monomer 100 is installed, and the installation process is the same as the above embodiment, which will not be described in detail. After the second discharge monomer 100 is installed, the two discharge monomers 100 are connected. During the connection process, one end of the connecting plate 21 of the second discharge monomer 100 is placed on the first base pile 11 adjacent to the first discharge monomer 100. Then, the second cross beam 41 is poured between the two connecting plates 21 by concrete. After pouring, the first base pile 11 and the water retaining monomer 20 in the two discharge monomers 100 are fixedly connected. Then, the longitudinal beam 42 is poured between the second base piles 12 by concrete, and three longitudinal beams 42 are poured between the two discharge monomers 100, so that the second base piles 12 between the two discharge monomers 100 are fixedly connected, to complete the connection of the two discharge monomers 100. The subsequent installation process is to install and connect the plurality of discharge monomers 100 in sequence, which is the same as the description in the above embodiment, and will not be described in detail. Finally, the installation of the entire cooling water discharge structure is completed.

[0050] In the embodiment, the first base pile 11 and the second base pile 12 are connected by the cross beam 41 poured by concrete, the two adjacent second base piles 12 are connected by the longitudinal beam 42, the different connecting plates 21 are connected by the cross beam 41, and the second water retaining plate 23 and the connecting plate 21, and the connecting plate 21 and the first base pile 11 are connected by concrete pouring. The main reason is that the concrete has strong plasticity and low cost, which is convenient for installation. Of course, in other embodiments, the pouring sequence can be different from the above embodiment, or other connection methods known to those skilled in the art can be used to connect the first base pile 11 and the second base pile 12, the connecting plate 21, or the adjacent first base pile 11 and the second base pile 12, which can be determined according to the actual situation, and the present disclosure does not limit it.

[0051] In an embodiment of the present disclosure, referring to Figure 3The second water retaining plate 23 is located between two adjacent cross beams 41 and is fixedly connected with the two cross beams 41. In this embodiment, the pouring of the second water retaining plate 23 is simultaneously performed during the pouring of the two cross beams 41. The pouring is performed from the upper edge of the connecting plate 21, and the two ends are poured together with the two cross beams 41 on the two sides. In this way, the second water retaining plate 23 is formed as a whole with the cross beams 41, the connecting plate 21 and the first foundation pile 11. When a larger water flow impact force is received, the cross beams 41 and the first foundation pile 11 can share the impact force, so that the second water retaining part 23 has a better water retaining effect.

[0052] In one embodiment of the present disclosure, referring to Figure 3 and Figure 4 The thickness of the connecting plate 21 along the discharge direction 5 is greater than the thickness of the first water retaining plate 22 and the second water retaining plate 23. In this way, when the water retaining monomer 20 is temporarily placed on the upper end of the first foundation pile 11 through the connecting plate 21, it is more stable and will not easily deflect or move under the influence of some external environment or human factors, thereby improving the stability of the water retaining monomer 20 when it is not connected with other water retaining monomers 20.

[0053] In this embodiment, in order to further improve the stability of the connecting plate 21 on the upper end of the first foundation pile 11 when adjacent water retaining monomers 20 are not connected, referring to Figure 6 a support table 10 is further provided on the upper end of the first foundation pile 11. The support table 10 can be a steel bracket or other mechanism with a supporting function. The support table 10 is located on the upper end of the first foundation pile 11 and is respectively located on the two ends of the first foundation pile 11 opposite to the discharge direction 5. When the connecting plate 21 is temporarily placed on the upper end of the first foundation pile 11, the bottom surface thereof can be in contact with the support table 10, so that the connecting plate 21 can be supported by the support table 10, thereby being more stable. In this embodiment, the thickness of the connecting plate 21 along the discharge direction 5 is greater than the thickness of the first water retaining plate 22 and the second water retaining plate 23, and the support table 10 is provided on the upper end of the first foundation pile 11, and the two work together to ensure the stability of the connecting plate 21 on the upper end of the first foundation pile 11. Of course, in other embodiments, the two measures can also be provided separately, for example, only the support table 10 is provided or only the width of the connecting plate 21 is changed, which can be determined according to the actual situation, and the present disclosure does not limit this.

[0054] In one embodiment of the present disclosure, the outer part of the first foundation pile 11, the second foundation pile 12 and the support table 10 is coated with a seawater corrosion resistant coating, thereby increasing the service life of the first foundation pile 11 and the second foundation pile 12, and ensuring that the materials therein will not be corroded even when they are subjected to the impact of seawater for a long time.

[0055] The coastal power plant cooling water discharge structure of the present disclosure, after installation is completed, when the cooling water is discharged, first enters into the seawater adjacent to the water inlet, and this part of seawater is located in the range enclosed by the first foundation pile 11 and the second foundation pile 12, with the cooling water flowing with the seawater to the discharge structure, the seawater with a higher height is blocked by the first water baffle 22 and the second water baffle 23, so that it will not be discharged into the seawater with the same height, but will flow downward to the drain 3 for discharge, thereby limiting the discharge height of the cooling water, avoiding the temperature of the surface layer of seawater being increased due to the cooling water being discharged into the seawater with a shallow layer, and further affecting the marine environment and the nearby fishery and aquaculture.

[0056] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present disclosure within the technical concept of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0057] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present disclosure will not further describe various possible combination manners.

[0058] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as it does not deviate from the idea of the present disclosure, and it should be considered as the disclosed content of the present disclosure.
