Description

Technical Field

[0001] This utility model relates to the field of marine engineering construction technology, and in particular to a drainage cylinder and drainage system. Background Technology

[0002] A nuclear power plant's drainage system typically includes an undersea tunnel and a drainage riser. One end of the drainage riser is connected to the top of the undersea tunnel, while the other end is open and extends upwards out of the seabed, allowing water from the undersea tunnel to be discharged into the sea. The top of the drainage riser is also equipped with a drainage cylinder (also known as a drainage grid). The bottom and sides of the drainage cylinder are open, while the top is closed, which deflects the vertically upward drainage from the drainage riser to a horizontal direction, thereby reducing the impact of drainage operations on surrounding maritime transport and the environment.

[0003] Since drainage risers are generally installed by jacking, the drainage cylinder needs to be transported by ship to the vicinity of the drainage riser after it has been lifted out of the seabed. Divers then align the flange at the bottom of the drainage cylinder with the flange at the top of the drainage riser underwater, and finally insert bolts to connect the drainage cylinder and the drainage riser. However, underwater flange alignment is extremely difficult due to environmental factors such as ocean currents, swells, and tides. This not only slows down the construction progress of the entire drainage system but also poses a risk of damage caused by collisions between the drainage cylinder and the drainage riser. Therefore, there is an urgent need to develop a drainage cylinder that is faster and safer to install. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing drainage cylinders, such as high installation difficulty, slowing down the construction progress of drainage systems, and the risk of collision between drainage cylinders and drainage risers, and to provide a drainage cylinder and drainage system.

The width of the guide structure is set along the radial direction of the cylinder and gradually decreases in the direction away from the cylinder. The guide structure can be inserted into the outlet of the drainage riser. The guide rope can pass through the through hole on the cylinder and the through hole on the second flange at the top of the drainage riser.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0019] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

[0023] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0024] Example 1 like Figures 1 to 4 As shown, a drainage cylinder includes a cylinder body 1, a guide structure 2, and a guide rope 3.

[0025] One end of the cylinder 1 is closed along its axial direction, and the other end is open; a first flange 11 is provided around the opening; a drain outlet is provided on the side wall of the cylinder 1, and at least two drain outlets are distributed at intervals along the circumference of the cylinder 1.

[0026] Guide structure 2 is connected to one end of the opening of cylinder 1. The width of guide structure 2 is set radially along cylinder 1, and the width of guide structure 2 gradually decreases in the direction away from cylinder 1; for example, if the outer contour of guide structure 2 is in Figure 3 If the projection of the guide structure 2 onto the ZOY plane (the plane perpendicular to the X-axis) is a square, then the side length of the square is smaller the further away from the cylinder 1; if the projection of the outer contour of the guide structure 2 onto the ZOY plane is a circle, then the diameter of the circle is smaller the further away from the cylinder 1; and the maximum width of the guide structure 2 is less than or equal to the width of the drainage riser 4, so that the guide structure 2 can be inserted into the outlet of the drainage riser 4.

[0027] The guide rope 3 can pass through the through hole on the cylinder 1 and the through hole on the second flange 41 at the top of the drainage riser 4.

[0028] exist Figures 1 to 4 The diagram also uses a rectangular coordinate system to mark each direction, where the X-axis represents the axial direction of cylinder 1, and the Y-axis and Z-axis represent two mutually perpendicular radial directions on cylinder 1.

[0029] When installing the drainage cylinder, fix one end of the guide rope 3, and pass the other end through the through hole on the cylinder 1 and the through hole on the second flange 41 at the top of the drainage riser 4 and fix it. Then, when lowering the cylinder 1, the guide rope 3 can limit the relative position of the cylinder 1 and the drainage riser 4 in the horizontal direction, so that the first flange 11 can always maintain initial alignment with the second flange 41 during the lowering of the cylinder 1, and avoid the cylinder 1 swaying too much relative to the drainage riser 4, which would cause the cylinder 1 and the drainage riser 4 to collide with each other.

[0030] As the cylinder 1 continues to approach the drainage riser 4, the guide structure 2 at the bottom of the cylinder 1 will preferentially insert into the drainage riser 4. Due to the shape of the guide structure 2, which is smaller at the bottom and larger at the top, there is a horizontal gap between the outer wall of the guide structure 2 and the inner wall of the drainage riser 4 when the guide structure 2 is first inserted into the drainage riser 4. Therefore, even if there is a horizontal positional deviation between the cylinder 1 and the drainage riser 4, the guide structure 2 can still be smoothly inserted into the drainage riser 4. As the cylinder 1 continues to descend, the gap between the outer wall of the guide structure 2 and the inner wall of the drainage riser 4 will gradually decrease, thereby enabling the cylinder 1 and the drainage riser 4 to be further aligned. This can significantly reduce the underwater alignment difficulty and installation difficulty of the cylinder 1, and improve the installation efficiency of the cylinder 1.

[0031] In summary, during installation, the drainage cylinder can be guided by the guide structure 2 and the guide rope 3, thereby reducing the installation difficulty of the cylinder 1, improving the installation efficiency of the cylinder 1, and reducing the risk of collision between the drainage riser 4 of the cylinder 1 and the other pipe.

[0032] In optional embodiments, the cylinder 1 may adopt existing technology, including but not limited to steel cylinder 1, reinforced concrete cylinder 1 or steel-concrete structure cylinder 1.

[0033] In an optional embodiment, the upper end of the guide rope 3 (the end away from the drainage riser 4) is connected to a vessel or a floating platform, for example, to a crane or winch on the vessel, or to a crane or winch on the floating platform, so that the guide rope 3 can be tightened by the crane or winch, thereby improving the limiting effect of the guide rope 3 on the cylinder 1.

[0034] In optional embodiments, the lower end of the guide rope 3 (the end closest to the drainage riser 4) is temporarily connected to the drainage riser 4 or the seabed, for example, by temporarily welding the guide rope 3 to the second flange; or by passing the guide rope 3 through the through hole of the second flange 41 and then detachably connecting a stop structure (e.g., a stop block or stop ring with a diameter larger than the diameter of the through hole) to the lower end of the guide rope 3 to prevent the guide rope from being pulled out of the second flange; or by binding a weight to the lower end of the guide rope 3 to sink it to the seabed; or by anchoring the lower end of the guide rope 3 to the seabed.

[0035] In an optional embodiment, the guide structure 2 is divided into at least two segments 21 along the axial direction of the cylinder 1, and the width of the segment 21 decreases more rapidly the further away from the cylinder 1; for example... Figure 2 As shown, the guide structure 2 is divided into two segments 21, wherein the width of the segment 21 closer to the cylinder 1 decreases more slowly, while the width of the segment 21 farther away from the cylinder 1 decreases more rapidly.

[0036] If the guide structure 2 has only one slope (the speed at which the width decreases along the axis of the cylinder 1), then the guide structure 2 will either be too short due to an excessively large slope, resulting in an unstable connection between the cylinder 1 and the drainage riser 4; or it will be too long due to an excessively small slope, resulting in an increased manufacturing cost for the guide structure 2. Therefore, in this embodiment, the guide structure 2 is divided into at least two segments 21 with different slopes. The segment 21 with a larger slope is more conducive to guiding the guide structure 2 to be inserted into the drainage riser 4 more smoothly, and then quickly transitions to the segment 21 with a larger width and a smaller slope. The segment 21 with a smaller slope has a smaller gap with the inner wall of the drainage structure, which can suppress the tilting of the guide structure 2 relative to the drainage riser 4, thereby improving the connection stability between the cylinder 1 and the drainage riser 4.

[0037] In an optional embodiment, the width of the guide structure 2 at the end furthest from the cylinder 1 gradually decreases to zero, for example... Figure 2 As shown, the side view of the segment 21 furthest from the cylinder 1 is triangular, which makes it easier to insert the end furthest from the cylinder 1 into the drainage riser 4, thereby further improving the installation efficiency of the cylinder 1 and further improving the adaptability of the cylinder 1 installation operation to the positional deviation of the cylinder 1.

[0038] In an optional implementation, the guide structure 2 is a frame structure made of spliced ​​steel sections.

[0039] Compared with other structural forms, such as plate-shaped guide structure 2 or block-shaped guide structure 2, this embodiment can reduce the material consumption of guide structure 2, thereby reducing the production cost of guide structure 2; on the other hand, it can also reduce the encroachment of guide structure 2 on the effective flow area of ​​cylinder 1, thereby avoiding the negative impact of guide structure 2 on the drainage efficiency of drainage riser 4.

[0040] In an optional implementation, the steel profiles can be existing products, including but not limited to angle steel, channel steel, or H-beams.

[0041] In an optional embodiment, at least two steel sections are connected by diagonal braces 22, the length direction of the diagonal braces 22 forming a non-zero angle with the axial direction of the cylinder 1; for example... Figure 1 and Figure 2 As shown, for the quadrangular prism-shaped segment 21 in the figure, the diagonal brace 22 is set between the two diagonally opposite steel sections, thus forming an X-shaped reinforcing structure.

[0042] This embodiment can enhance the strength and rigidity of the guide structure 2, and prevent the guide structure 2 from deforming due to contact with the drainage riser 4, thereby negatively affecting its guiding and centering functions.

[0043] In an optional embodiment, the number of guide ropes 3 is at least two, and the guide ropes 3 are distributed at intervals along the circumference of the cylinder 1, so as to produce a better limiting effect on the cylinder 1 from at least two different directions, further reducing the risk of the cylinder 1 colliding with the drainage riser 4, and improving the efficiency of aligning the cylinder 1 with the drainage riser 4.

[0044] In an optional embodiment, additional structures such as ear plates and sleeves can be provided on the cylinder 1 to thread the guide rope 3, or holes can be drilled in the cylinder 1 to also provide the guide rope 3.

[0045] In an optional embodiment, the guide rope 3 passes through a through hole on the first flange 11.

[0046] This embodiment utilizes the existing through-hole on the first flange 11 to thread the guide rope 3, which can make the most of the existing structure on the cylinder 1, thereby reducing the need for modification to the cylinder 1 and helping to reduce the manufacturing cost of this embodiment.

[0047] In an optional embodiment, at least two guide ropes 3 pass through two through holes located diagonally opposite each other on the first flange 11.

[0048] This embodiment can guide the cylinder 1 from the diagonal, which is beneficial for providing a better guiding effect to the cylinder 1 with as few guide ropes 3 as possible, and also for initially aligning the through holes on the first flange 11 and the second flange 41.

[0049] In an optional embodiment, the guide rope 3 can be an existing product, specifically including but not limited to steel wire rope, nylon rope or aramid rope.

[0050] In an optional embodiment, a lifting lug 12 is connected to the end of the cylinder 1 away from the first flange 11.

[0051] In this embodiment, an independent lifting lug 12 is provided on the cylinder 1. When the cylinder 1 needs to be lowered, an additional lifting rope can be connected to the lifting lug 12, so that the lifting rope and the guide rope 3 are responsible for bearing the weight and guiding respectively. This helps to reduce the load on the guide rope 3, thereby reducing the difficulty of controlling the guide rope 3 and the risk of breakage.

[0052] In an optional embodiment, the number of lifting lugs 12 is at least two, and the lifting lugs 12 are distributed at intervals along the circumference of the cylinder 1.

[0053] In an optional embodiment, a sacrificial anode 13 is also connected to the cylinder 1 to prevent electrochemical corrosion of the cylinder 1.

[0054] Example 2 A drainage system includes a drainage riser 4, the top of which is connected to any of the drainage cylinders in Embodiment 1.

[0055] This embodiment improves the construction efficiency of the drainage system and enhances the connection stability between the drainage riser 4 and the drainage cylinder by connecting the top of the drainage riser 4 to the drainage cylinder in embodiment 1.

[0056] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
