Abstract
Description
Technical Field
[0001] The invention relates to a cable routing structure, in particular to an anti-corrosion cable routing structure suitable for offshore platforms. Background Art
[0002] Due to the complex environment of offshore platforms, cables may be exposed to moisture, salt spray, high or low temperatures for a long time. Therefore, cables need to have good corrosion resistance, waterproofness, and weather resistance. In addition, they need to have a more adaptable cable tray structure to adapt to cable routing in extreme weather conditions.
[0003] In the prior art, cable trays used for cable routing are mostly trough-type, tray-type and other structures. Due to the need to adapt to the marine environment, they are generally made into sealed trough structures. Although this can prevent rainwater from entering the trough during rain or storm accumulation, affecting the drying of cables and cable trays and reducing the corrosion effect of seawater, it also leads to poor heat dissipation, which in turn affects the service life of the cables. Summary of the Invention
[0004] In order to solve the above technical problems, the purpose of the present invention is to provide an anti-corrosion cable routing structure suitable for offshore platforms, which not only has a good heat dissipation effect, but also can automatically seal when rainwater or seawater accumulates to handle the accumulated liquid.
[0005] The present invention provides the following technical solutions:
[0006] The cable duct is provided with a plurality of holes, the holes being arranged on the top and bottom of the cable duct so as to allow the cable to pass through the cable duct and the bottom of the cable duct to pass through the cable duct. The flow hole is connected to the one-way valve through a pipe to discharge flow in one direction. The bottom of the discharge chamber is provided with a vent. At this time, on the basis of the vent, through hole one and through hole two providing ventilation and heat dissipation, the arched design can also prevent fluid accumulation from entering the arched chamber through through hole one and through hole two. That is, unless the accumulated liquid accumulates to the top of the arch, the arched chamber will not accumulate a large amount of liquid from through hole one and through hole two. In a humid environment, it is inevitable that the humid air flow entering the arched chamber and the heat dissipation chamber will form liquid in the arched chamber. The arched design can ensure that the accumulated liquid flows to both ends and then flows out through the leakage hole and the one-way valve, thereby avoiding the residue of the accumulated liquid in the arched chamber. Similarly, when the bottom trough and the top trough are covered, the accumulated liquid may also enter the arched chamber due to poor sealing. At this time, the accumulated liquid entering the arched chamber will also flow out through the leakage hole and the one-way valve.
[0007] Preferably, auxiliary cavity 1 is extended outward on both sides of the top groove, and auxiliary cavity 2 is extended outward on both sides of the bottom groove. When the auxiliary cavity 1 and the auxiliary cavity 2 are relatively pressed together, they are used to cover the top groove and the bottom groove. The extended cavity can not only improve the stability of the covering connection, but also provide stable support for further structural design.
[0008] Preferably, a plurality of heat dissipation holes 1 are provided on the side where the auxiliary cavity 1 is connected to the heat dissipation cavity, and the heat dissipation holes are arranged through the auxiliary cavity 1 and the heat dissipation cavity, and a heat dissipation hole 2 is provided on the side of the auxiliary cavity 1 facing away from the heat dissipation cavity. The airflow can be realized through the heat dissipation hole 1, the auxiliary cavity 1, the heat dissipation hole 2, the heat dissipation cavity, the arched cavity, the discharge cavity and the vent to keep the interior of the structure dry and avoid liquid accumulation and corrosion. The auxiliary cavity 1 between the heat dissipation hole 1 and the heat dissipation hole 2 can achieve the effect of airflow transition buffering.
[0009] Preferably, the heat dissipation hole 2 is replaced by a blower connected to one side of the auxiliary chamber 1 through an air pipe. When the blower is started, the air flow is realized through the auxiliary chamber 1, the heat dissipation chamber, the arched chamber, the discharge chamber, and the vent, so as to more efficiently keep the interior of the structure dry and avoid liquid accumulation and corrosion.
[0010] Preferably, a pressure gauge is connected to the air pipe, and multiple groups of heat dissipation holes are distributed side by side along the extension direction of the top groove. The heat dissipation hole is a triangular channel. The auxiliary chamber 2 is also guided and connected to multiple groups of triangular sealing blocks. The triangular sealing blocks are arranged in a one-to-one correspondence with the heat dissipation hole. The bottom end of each group of triangular sealing blocks is also connected to a group of floats through a suspension rod. The bottom end of the auxiliary chamber 2 is also provided with a bottom hole. Therefore, when liquid enters the auxiliary chamber 2 from the bottom, the accumulated liquid will lift the float after entering the auxiliary chamber 2, and as the liquid level rises, the heat dissipation hole 1 can be completely sealed. At this time, the blower blows air into the structure, which can cause the pressure to rise due to the sealing of the vent due to the accumulated liquid. At this time, personnel can be prompted to promptly discover the occurrence of accumulated liquid for response and treatment.
[0011] Preferably, the bottom end of the triangular sealing block is also connected to a group of adjustment plates corresponding to the covers outside the vents through a connecting block. When the float is at the lowest end, the adjustment plates cover the vents, and a ventilation gap is left with the bottom end of the vents. When the float rises, the adjustment plates also rise, and the opening of the vents will also increase when rising. The accumulated liquid can flow into the discharge cavity through the vents, so that the accumulated liquid can be uniformly treated later.
[0012] Preferably, the leakage chamber is connected to a leakage pump through a pressure relief pipe at the bottom. When the pressure value detected by the pressure gauge exceeds the standard, the triangular sealing block is sealed in the heat dissipation hole 1, and the opening of the vent is maximum. The controller controls the blower to turn off and turns on the leakage pump to extract the accumulated liquid in the leakage chamber.
[0013] Preferably, the top frame and the bottom frame are V-shaped with openings arranged opposite to each other, and the bottom frame and the top frame are detachably connected to the corresponding arched support plates and arched pressure plates by screws, so as to facilitate subsequent replacement and maintenance.
[0014] The beneficial effect of the present invention is that the present invention provides an anti-corrosion cable routing structure suitable for offshore platforms, which not only has a good heat dissipation effect, but also can automatically seal when rainwater or seawater accumulates to facilitate the treatment of accumulated liquid. In the specific design structure, the vent, through hole 1 and through hole 2 can provide ventilation and heat dissipation. The arched design can prevent the accumulated fluid from entering the arched cavity through through hole 1 and through hole 2, that is, unless the accumulated fluid accumulates to the top of the arch, the arched cavity will not allow a large amount of liquid to enter the arched cavity through through hole 1 and through hole 2. In a humid environment, it is inevitable that the humid airflow entering the arched cavity and the heat dissipation cavity will form accumulated liquid in the arched cavity. The arched design can ensure that the accumulated liquid flows to both ends and then flows out through the drain hole and the one-way valve, thereby avoiding the residue of accumulated liquid in the arched cavity. Similarly, when the bottom trough and the top trough are covered, accumulated liquid may also enter due to poor sealing. When the air in the vent is opened, the air in the vent is opened, and the vent is opened, so that the air in the vent is opened and the vent is opened. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1
[0024] like Figure 1 As shown, a corrosion-resistant cable 7 routing structure suitable for offshore platforms, in this embodiment, includes a bottom groove 1 and a top groove 2 connected together, an arched support plate 3 protruding toward the top groove 2 is provided in the bottom groove 1, and an arched pressure plate 4 protruding in the direction away from the bottom groove 1 is provided in the top groove 2. A plurality of groups of bottom frames 5 distributed along an arc are arranged on the arched support plate 3, and a plurality of groups of top frames 6 distributed along an arc are arranged on the arched pressure plate 4. The openings of the top frame 6 and the bottom frame 5 are arranged relative to each other and are one-to-one corresponding for use The clamp is positioned outside the cable 7, and an arched cavity 8 for positioning the cable 7 is formed between the arched support plate 3 and the arched pressure plate 4 and the side wall of the bottom groove 1. A drainage cavity 9 is formed between the arched support plate 3 and the bottom of the bottom groove 1, and a heat dissipation cavity 10 is formed between the arched pressure plate 4 and the bottom of the top groove 2. The top of the arched support plate 3 and the arched pressure plate 4 are respectively provided with a through hole 11 connected to the drainage cavity 9 and a through hole 2 12 connected to the heat dissipation cavity 10. The drainage cavity 9 and the arched ends of the arched cavity 8 are provided with a drainage hole 1 3. The drain hole 13 is connected to the one-way valve through a pipe to drain out in one direction. A vent 14 is provided at the bottom of the drain cavity 9. At this time, while the vent 14, the through hole 11 and the through hole 2 12 provide ventilation and heat dissipation, the arch design can also prevent the accumulation of fluid from entering the arch cavity 8 through the through hole 11 and the through hole 2 12. That is, unless the accumulated fluid accumulates to the top of the arch, the phenomenon of a large amount of fluid entering the arch cavity 8 through the through hole 11 and the through hole 2 12 will occur in the arch cavity 8. In the humid Under certain environmental conditions, it is inevitable that moist airflow entering the arched cavity 8 and the heat dissipation cavity 10 will form liquid accumulation in the arched cavity 8. The arched design can ensure that the accumulated liquid flows to both ends and then flows out through the drainage holes 13 and the one-way valve, thereby avoiding the residual accumulated liquid in the arched cavity 8. Similarly, when the bottom groove 1 and the top groove 2 are covered, the poor sealing may also cause the accumulated liquid to enter the arched cavity 8. At this time, the accumulated liquid entering the arched cavity 8 will also flow out through the drainage holes 13 and the one-way valve.
[0025] Example 2
[0026] like Figure 2-5 As shown, a corrosion-resistant cable 7 routing structure suitable for offshore platforms, in this embodiment, is further limited based on embodiment 1, and auxiliary cavities 15 are extended outward on both sides of the top groove 2, and auxiliary cavities 2 16 are extended outward on both sides of the bottom groove 1. When the auxiliary cavities 15 and 16 are relatively crimped, they are used to perform a covering connection between the top groove 2 and the bottom groove 1, and the extended cavity can not only improve the stability of the covering connection, but also provide stable support for further structural design.
[0027] A plurality of heat dissipation holes 17 are provided on one side where the auxiliary chamber 15 and the heat dissipation chamber 10 are connected. The heat dissipation holes are provided through the auxiliary chamber 15 and the heat dissipation chamber 10. A blower is connected to one side of the auxiliary chamber 15 through an air pipe 18. When the blower is started, the air flow is realized through the auxiliary chamber 15, the heat dissipation chamber 10, the arched chamber 8, the discharge chamber 9, and the vent 14, so as to more efficiently keep the interior of the structure dry and avoid liquid accumulation and corrosion.
[0028] A pressure gauge is connected to the air pipe 18, and multiple groups of heat dissipation holes 17 are distributed side by side along the extension direction of the top groove 2. The heat dissipation holes 17 are triangular channels. The auxiliary chamber 2 16 is also connected to multiple groups of triangular sealing blocks 19. The triangular sealing blocks 19 are arranged in a one-to-one correspondence with the heat dissipation holes 17. The bottom end of each group of triangular sealing blocks 19 is also connected to a group of floats 20 through a hanger. The bottom end of the auxiliary chamber 2 16 is also provided with a bottom hole 21. Therefore, when the auxiliary chamber 2 16 enters the accumulated liquid from the bottom, the accumulated liquid will lift the float 20 after entering the auxiliary chamber 2 16, and as the liquid level rises, the heat dissipation holes 17 can be completely sealed. At this time, the blower blows air into the structure, which can cause the pressure to rise due to the sealing of the vent 14 due to the accumulated liquid. At this point, personnel can be prompted to promptly discover the accumulation of liquid for timely treatment.
[0029] The bottom end of the triangular sealing block 19 is also connected to a set of adjustment plates 22 corresponding to the cover outside the vent 14 through a connecting block. When the float 20 is at the lowest end, the adjustment plate 22 covers the vent 14, and a ventilation gap is left with the bottom end of the vent 14. When the float 20 rises, the adjustment plate 22 also rises. When rising, the opening of the vent 14 will also open wider, and the accumulated liquid can flow into the discharge chamber 9 through the vent 14, so that the accumulated liquid can be uniformly treated later.
[0030] The discharge chamber 9 is connected to a discharge pump through a pressure relief pipe at the bottom. When the pressure value detected by the pressure gauge exceeds the standard, the triangular sealing block 19 is sealed in the heat dissipation hole 17, and the opening of the vent 14 is maximum. The controller controls the blower to turn off and turns on the discharge pump to extract the accumulated liquid in the discharge chamber 9.
[0031] The top frame 6 and the bottom frame 5 are V-shaped with openings facing each other, and the bottom frame 5 and the top frame 6 are detachably connected to the corresponding arched support plate 3 and the arched pressure plate 4 by screws, so as to facilitate subsequent replacement and maintenance.
[0032] The working principle of the present invention is as follows: the present invention provides an anti-corrosion cable 7 routing structure suitable for offshore platforms, which not only has a good heat dissipation effect, but also can automatically seal when rainwater or seawater accumulates to facilitate the treatment of accumulated liquid. In the specific design structure, the vent 14, through hole 11 and through hole 2 12 can provide ventilation and heat dissipation. The arch design can prevent fluid accumulation from entering the arch cavity 8 through through hole 11 and through hole 2 12, that is, unless the accumulated liquid accumulates to the top of the arch, the arch cavity 8 will not allow a large amount of liquid to enter the arch cavity 8 through through hole 11 and through hole 2 12. In a humid environment, it is inevitable that the humid airflow entering the arch cavity 8 and the heat dissipation cavity 10 will form accumulated liquid in the arch cavity 8. The arch design can ensure that the accumulated liquid flows to both ends and then flows out through the drain hole 13 and the one-way valve, thereby avoiding the residual accumulated liquid in the arch cavity 8. Similarly, when the bottom groove 1 and the top groove 2 are covered, the poor sealing may also cause accumulated liquid to enter the arch The effluent entering the arched cavity 8 at this time will also flow out through the drain hole 13 and the one-way valve. When the blower is operated, the airflow is realized through the auxiliary cavity 15, the heat dissipation cavity 10, the arched cavity 8, the drain cavity 9, and the vent 14 to achieve the flow of airflow, so as to more efficiently keep the internal dryness of the structure and avoid the occurrence of effluent corrosion. When the structure of the float 20 is adopted, if the effluent enters the auxiliary cavity 2 16 from the bottom, the effluent will lift the float after entering the auxiliary cavity 2 16. 20, and as the liquid level rises, the heat dissipation hole 17 can be completely sealed. At this time, the blower blows air into the structure, which can cause the pressure to rise due to the sealing of the vent 14 due to the accumulated liquid. At this point, it can prompt personnel to discover the accumulation of liquid in time for corresponding treatment. The specific operation is that when the pressure gauge detects that the pressure value exceeds the standard, the triangular sealing block 19 is sealed in the heat dissipation hole 17, and the opening of the vent 14 is the maximum. The controller controls the blower to close and turns on the drainage pump to extract the accumulated liquid in the drainage chamber 9.
