Description

Technical Field

[0001] The invention belongs to the technical field of cable supports, and in particular relates to an underwater cable support frame that is surge-proof. Background Art

[0002] In the construction of offshore platforms, fixed devices such as jackets are often used to build and fix structures such as pipelines. In shallow and offshore areas, the surges generated by the tidal action of the sea water cause crustaceans in the ocean to attach to the jackets by secreting mucus or using their silk feet, shells and other structures. After long-term use, the structural strength of the jacket close to the sea level will decrease due to the scouring of tidal surges, increasing the risk of structural failure. Secondly, the enrichment of crustaceans will cause changes in the fluid dynamics performance of the jacket, increase the resistance of the jacket, and further increase the damage to the jacket from tidal surges.

[0003] The current method of preventing crustaceans from attaching to the conductor frame is usually to apply non-toxic coatings and coatings containing biotoxic substances on the surface of the conductor frame, and prevent crustaceans from attaching through smooth surfaces or surfaces containing biotoxic substances. However, coatings containing biotoxic substances will pollute the marine environment, and there is a durability problem in the way of using coatings. The smooth coating surface will be hit by the shells of crustaceans and other marine debris during long-term use, resulting in a rough surface, thereby losing the anti-fouling effect and even providing crustaceans with better attachment points. Therefore, the coating surface needs to be maintained regularly, and the cost of high-quality anti-fouling coatings is high. For large offshore platforms, the coating cost is very expensive, which greatly increases the maintenance cost of the conductor frame. Summary of the invention

[0011] Preferably, the large gear ring has symmetrical notches, so that the small gear is intermittently disengaged when rotating along the large gear ring.

[0012] Preferably, an annular groove is provided on the inner side surface of the lower sleeve, a plurality of centrally symmetrical locking grooves are provided on the bottom surface of the annular groove, a sliding groove is provided on the outer bracket and a sliding block is slidably connected to the inside thereof, an inclined plate is rotatably mounted on the bottom of the outer side surface of the sliding block, a magnetic block is fixedly connected to the top of the outer side surface of the sliding block, and the magnetic block is embedded in a locking groove.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, through the cleaning mechanism set up, when the sea water rises in tide, as the tide approaches the bracket mechanism, it will first push the inclined plate upward, thereby causing the sliding block to move upward, and then the magnetic block moves into the annular groove, and then as the sea water continues to move forward, it pushes the lower sleeve and the upper sleeve to rotate, and as the lower sleeve and the upper sleeve rotate, it drives the small gear to rotate around the large gear ring, so that the small gear drives the first rotating shaft to rotate, and the first rotating shaft winds the first rope around itself, and as the first rope is wound, it drives the sliding frame connected to it to slide, thereby loosening the second rope from the second rotating shaft, and as the sliding frame slides, the folding film opens to increase the contact area between the cleaning mechanism and the tide, so as to provide sufficient rotational power to the lower sleeve, and while the first rope is being wound, the third rope is pulled, thereby tightening the connecting rod group, at this time the cleaning brush contacts the cross support, and as the lower sleeve rotates, the connecting frame rotates together with the side arm, so that the cleaning brush automatically cleans the cross support.

[0015] 2. Secondly, when the small gear rotates with the lower sleeve and no longer meshes with the teeth of the large gear ring, the reset spring on the first rotating shaft controls the first rotating shaft to rotate in the opposite direction, and the reset spring on the second rotating shaft controls the second rotating shaft to rotate in the opposite direction. After the first rotating shaft and the second rotating shaft rotate in the opposite direction, the second rope is rewound around the second rotating shaft, and drives multiple sliding frames to move in the direction of the lower sleeve and fold the folding film. At this time, the items attached to the folding film will be bounced off during the process of retracting and releasing the folding film, preventing debris from adhering to the folding film. At the same time, the sliding of the sliding frame will also scratch the outer surface of the side arm, thereby scraping off the debris attached to the side arm, preventing the debris from adhering to and accumulating on the side arm and the folding film and causing malfunction.

[0016] 3. Finally, by setting the inclined plate, at high tide, the rising force of the tide will push the sliding block upward, so that the magnetic block will no longer lock the lower sleeve. At low tide, the downward pressure of the tide will push the inclined plate diagonally downward, thereby driving the sliding block to move downward, so that the magnetic block is embedded in the locking groove, preventing the sea breeze from blowing the cleaning mechanism and causing the cleaning brush to be wetted by sea water to clean the cross support, causing the cleaning brush to wear out prematurely.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 8As shown, an embodiment of the present invention provides a surge-proof underwater cable support frame, including a support mechanism 1, the support mechanism 1 includes an outer support 11 and a cable sleeve 12 fixedly installed inside the outer support 11, and also includes: a cleaning mechanism 2, the cleaning mechanism 2 includes a lower sleeve 21 and an upper sleeve 22, the lower sleeve 21 and the upper sleeve 22 are both rotatably mounted on the outer support 11, the outer side surfaces of the lower sleeve 21 and the upper sleeve 22 are fixedly sleeved with a connecting frame 23, there is a gap between the lower sleeve 21 and the upper sleeve 22, a symmetrical first rotating shaft 27 is rotatably mounted on the outer side surface of the lower sleeve 21, a small gear 28 is fixedly sleeved on the first rotating shaft 27, a large gear ring 212 is fixedly sleeved on the outer support 11, and the large gear ring 212 is rotatably mounted on the outer side surface of the lower sleeve 21. The pinion 28 is meshed, and side arms 24 are fixedly connected on both sides of the outer bracket 11. A connecting rod group 216 is hinged between the side arm 24 and the lower sleeve 21 and the upper sleeve 22. A plurality of cleaning brushes 217 are fixedly connected to the connecting rod group 216. A third rope 218 is arranged in the connecting rod group 216. A first rope 29 is arranged inside the side arm 24. A plurality of sliding frames 25 are slidably sleeved on the outer surface of the side arm 24. One end of the first rope 29 is wound around the first rotating shaft 27, and the other end thereof passes through the side arm 24 and is fixedly connected to a sliding frame 25. The first rope 29 bypasses the third rope 218. When the first rope 29 is wound, the length of the third rope 218 in the side arm 24 increases.

[0028] In the present invention, by setting the cleaning mechanism 2, when the seawater is in high tide, as the tide approaches the support mechanism 1, it will first push the inclined plate 226 upward, thereby moving the sliding block 224 upward, and then the magnetic block 225 moves into the annular groove 213, and then as the seawater continues to move forward, it pushes the lower sleeve 21 and the upper sleeve 22 to rotate, and as the lower sleeve 21 and the upper sleeve 22 rotate, they drive the small gear 28 to rotate around the large ring gear 212, so that the small gear 28 drives the first rotating shaft 27 to rotate, and the first rotating shaft 27 winds the first rope 29 around itself, and as the first rope 29 rotates, the first rope 29 rotates. The rope 29 is wound, which drives the sliding frame 25 connected to it to slide, thereby loosening the second rope 211 from the second rotating shaft 210, and as the sliding frame 25 slides, the folding film 26 opens to increase the contact area between the cleaning mechanism 2 and the tide, so as to provide sufficient rotational power to the lower sleeve 21, and while the first rope 29 is being wound, the third rope 218 is pulled, thereby tightening the connecting rod group 216, at which time the cleaning brush 217 contacts the cross support, and as the lower sleeve 21 rotates, the connecting frame 23 and the side arm 24 rotate together, so that the cleaning brush 217 automatically cleans the cross support.

[0029] Secondly, when the small gear 28 rotates with the lower sleeve 21 and no longer meshes with the teeth of the large gear ring 212, the reset spring 219 on the first shaft 27 controls the first shaft 27 to rotate in the opposite direction, and the reset spring 219 on the second shaft 210 controls the second shaft 210 to rotate in the opposite direction. After the first shaft 27 and the second shaft 210 rotate in the opposite direction, the second rope 211 is rewound around the second shaft 210, and drives multiple sliding frames 25 to move in the direction of the lower sleeve 21 and retract the folding film 26. At this time, the items attached to the folding film 26 will be bounced off during the process of retracting and releasing the folding film 26, preventing debris from adhering to the folding film 26. At the same time, the sliding of the sliding frame 25 will also scrape the outer surface of the side arm 24, thereby scraping off the debris attached to the side arm 24, preventing the debris from adhering to and accumulating on the side arm 24 and the folding film 26 and causing malfunction.

[0030] Finally, by setting the inclined plate 226, at high tide, the rising force of the tide will push the sliding block 224 to move upward, so that the magnetic block 225 will no longer lock the lower sleeve 21, and at low tide, the downward pressure of the tide will push the inclined plate 226 diagonally downward, thereby driving the sliding block 224 to move downward, so that the magnetic block 225 is embedded in the locking groove 214, preventing the sea breeze from blowing the cleaning mechanism 2 to cause the cleaning brush 217 to be wetted by sea water to clean the cross support, causing the cleaning brush 217 to wear out prematurely.

[0031] Among them, the connecting rod group 216 includes a first connecting rod 220 hinged at the outermost side of the side arm 24 and the remaining multiple second connecting rods 221, the sides of the first connecting rod 220 and the second connecting rod 221 are both provided with a first sliding groove 222, the front end of the second connecting rod 221 is slidably connected in the first sliding groove 222 of the previous connecting rod, and the inside of the first connecting rod 220 and the second connecting rod 221 are provided with a connected rope groove 223, and the outlet of the rope groove 223 in the first connecting rod 220 is located on its side close to the side arm 24.

[0032] like Figures 2 to 7 As shown, the front end of the rear second link 221 is slidably connected to the inside of the front second link 221, and the third rope 218 connects the first link 220 and the second link 221 in series, so that when the third rope 218 is tightened, the second link 221 moves to the front end of the first slide groove 222 of the front link, reducing the length of the link group 216, and the link group 216 is transformed from a loose arc state to a combined state where the third rope 218 is pulled. At this time, the first link 220 and multiple second links 221 are in the same line, so that the link group 216 can provide sufficient force to support the cleaning brush 217 to clean the cross support.

[0033] Among them, multiple sliding frames 25 are fixedly connected with the folding film 26, and the internal rotation of the connecting frame 23 is symmetrically installed with a second rotating shaft 210, on which a second rope 211 is wound, and the other end of the second rope 211 passes through multiple sliding frames 25 and is fixedly connected thereto, and a reset spring 219 is fixedly connected to the bottom of the second rotating shaft 210, and the other end of the reset spring 219 is fixedly connected to the connecting frame 23, and another reset spring 219 is fixedly connected to the bottom end of the first rotating shaft 27, and the other end of the reset spring 219 is fixedly connected to the connecting frame 23.

[0034] like Figures 2 to 5 As shown, when the lower sleeve 21 and the upper sleeve 22 are driven to rotate by the waves, as the lower sleeve 21 rotates, the first rotating shaft 27 rotates under the meshing transmission of the pinion 28 and the large gear ring 212, thereby causing the first rope 29 to be wound around the first rotating shaft 27. As the first rope 29 is wound, the sliding frame 25 connected thereto is pulled and moves in a direction away from the lower sleeve 21. As the sliding frame 25 is pulled, it drives the second rope 211 to separate from the second rotating shaft 210, thereby driving the second rotating shaft 210 to rotate. As the pinion 28 rotates to the disconnection point of the large gear ring 212, the first rotating shaft 27 and the second rotating shaft 210 are reversed under the drive of the corresponding reset spring 219. At this time, the first rope 29 is no longer wound around the first rotating shaft 27, and the second rope 211 is rewound around the second rotating shaft 210, so that the first rotating shaft 27 and the second rotating shaft 210 are reset.

[0035] An inner groove 215 is opened inside the side arm 24, and the first rope 29 moves in the inner groove 215. The third rope 218 passes through the side arm 24 and connects the upper and lower connecting rod groups 216. The two ends of the third rope 218 are fixedly connected to the lower sleeve 21 and the upper sleeve 22 respectively.

[0036] like Figures 4 to 6 As shown, the first link 220 and the second link 221 in the link group 216 are both strung on the third rope 218. When the third rope 218 is not pulled by the first rope 29, the first link 220 and the second link 221 are in a loose state. At this time, the first link 220 and the second link 221 in the link group 216 make the link group 216 arc-shaped under the action of their own gravity. This allows the first link 220 and the second link 221 to reduce the impact of the surge thrust on the link group 216 by rising and falling with the waves, thereby increasing the service life of the link group 216.

[0037] The large gear ring 212 has symmetrical notches, so that the pinion 28 is intermittently disengaged when rotating along the large gear ring 212 .

[0038] like Figure 2 and Figure 3 As shown, the pinion 28 meshes with and separates from the large gear ring 212 as the lower sleeve 21 rotates. When the pinion 28 meshes with the large gear ring 212, the pinion 28 drives the first rotating shaft 27 to rotate, thereby causing the first rope 29 to be wound around the first rotating shaft 27. As the first rope 29 is wound, the third rope 218 is pulled by the first rope 29, so that the part of the third rope 218 located outside the side arm 24 is tightened, thereby causing the first connecting rod 220 and the second connecting rod 221 in the connecting rod group 216 to be converted from a loose state to a combined state. At this time, the cleaning brush 217 on the connecting rod group 216 will approach the adjacent cross support after the connecting rod group 216 is converted to the combined state, and clean the cross support as the lower sleeve 21 and the upper sleeve 22 rotate.

[0039] As the small gear 28 is disengaged from the large gear ring 212, that is, after the small gear 28 enters the position where the large gear ring 212 has a gap, the small gear 28 is no longer in contact with the large gear ring 212. At this time, the first rotating shaft 27 is driven by the reset spring 219 arranged at the bottom thereof to rotate in the opposite direction and reset, so that the first rope 29 is loosened, and at this time, the bottom reset spring 219 of the second rotating shaft 210 is also reset, so that the second rope 211 is rewound on the second rotating shaft 210. At this time, the folding film 26 is folded during the winding of the second rope 211, and the debris attached to the folding film 26 is shaken off. When the second rope 211 is wound up and the sliding frame 25 moves in the direction of the lower sleeve 21, the debris on the outer surface of the side arm 24 is also scraped off, thereby preventing crustaceans from adhering to the folding film 26 and the side arm 24, causing the cleaning mechanism 2 to fail to work normally.

[0040] Among them, the inner side surface of the lower sleeve 21 is provided with an annular groove 213, and the bottom surface of the annular groove 213 is provided with multiple centrally symmetrical locking grooves 214. The outer bracket 11 is provided with a sliding groove and a sliding block 224 is slidably connected inside it. An inclined plate 226 is rotatably installed at the bottom of the outer side surface of the sliding block 224, and a magnetic block 225 is fixedly connected to the top of the outer side surface of the sliding block 224, and the magnetic block 225 is embedded in a locking groove 214.

[0041] like Figure 4 and Figure 8As shown, in the initial state, the sliding block 224 and the magnetic block 225 are located below the sliding groove, and the inclined plate 226 is light in texture, so that it can keep the bottom surface horizontal. When the tide rises, as the tide contacts the inclined plate 226, the upward force of the tide pushes the inclined plate 226 upward, and the inclined plate 226 drives the sliding block 224 to move upward. At this time, the magnetic block 225 located in the locking groove 214 moves upward together with the sliding block 224 and enters the annular groove 213. At this time, the lower sleeve 21 can rotate freely. As the tide continues to move forward, it contacts the fins on the lower sleeve 21 and the upper sleeve 22 and the folding membrane 26 in the open state. At this time, the lower sleeve 21 and the upper sleeve The cylinder 22 will start to rotate under the push of seawater, so that the cleaning brush 217 will contact the cross support of the outer bracket 11 to sweep away the attachments on the cross support. The magnetic block 225 is used to increase the force driving the sliding block 224 to move and prevent the sea breeze from driving the inclined plate 226 to move, thereby causing the lower sleeve 21 and the upper sleeve 22 to be driven to rotate by the sea breeze, causing the cleaning brush 217 to contact the cross support part when it is not wetted by seawater, thereby causing the bristles of the cleaning brush 217 to wear out prematurely.

[0042] Working principle:

[0043] When a tide occurs, as the waves move toward the support mechanism 1, the sea water first contacts the inclined plate 226. At this time, the rising force of the rising tide pushes the inclined plate 226 obliquely upward, thereby driving the sliding block 224 to slide upward. At this time, the magnetic block 225 moves from the locking groove 214 to the annular groove 213, so that the lower sleeve 21 is no longer locked. Later, the waves at high tide contact the lower sleeve 21 and drive the lower sleeve 21 to rotate. At this time, the lower sleeve 21 will drive the upper sleeve 22 to rotate through the connecting frame 23 when rotating. When the lower sleeve 21 rotates, it drives the first rotating shaft 27 to rotate, so as to rotate the first rotating shaft 27. A rope 29 is wound around the first rotating shaft 27. At this time, as the first rope 29 is wound, the sliding frame 25 connected to the first rope 29 is pulled, so that the second rope 211 is pulled out from the second rotating shaft 210. At the same time, the folding membrane 26 is unfolded after the sliding frame 25 is pulled, thereby increasing the contact area between the cleaning mechanism 2 and the seawater, thereby increasing the thrust provided by the tide to the cleaning mechanism 2, so that the lower sleeve 21 can continue to rotate. At the same time, because part of the tidal force is used to drive the cleaning mechanism 2, the force exerted by the tide on the outer bracket 11 is reduced, thereby extending the service life of the outer bracket 11.

[0044] As the first rope 29 is wound around the first rotating shaft 27, the third rope 218 is pulled by the first rope 29, and its length in the inner groove 215 increases, that is, the length in the connecting rod group 216 decreases. At this time, the first connecting rod 220 and the second connecting rod 221 in the connecting rod group 216 are pulled by the third rope 218 to combine, and are converted from a loose state to a combined state and tightened. At this time, the cleaning brush 217 on the connecting rod group 216 contacts the cross support of the outer bracket 11, and as the lower sleeve 21 rotates, the cleaning brush 217 cleans the cross support to prevent debris such as crustaceans from adhering to the outer bracket 11 and corroding the outer bracket 11.

[0045] As the lower sleeve 21 continues to rotate, the small gear 28 no longer meshes with the large ring gear 212. At this time, the first shaft 27 rotates in the opposite direction under the action of the bottom reset spring 219, and the first rope 29 no longer provides traction. At the same time, due to the lack of traction, the reset spring 219 at the bottom of the second shaft 210 also rotates, so that the second rope 211 is wound around the second shaft 210. As the second rope 211 is tightened, the sliding frame 25 is pulled back by the second rope 211 to retract the folding film 26. At this time, the recovery of the sliding frame 25 will scrape off the attachments on the side arm 24, and the retraction of the folding film 26 will destroy the attachment surface of the attachment, thereby causing the attachment to fall off and leave the outer bracket 11 as the tide recedes. When the first rope 29 no longer provides traction, the third rope 218 is no longer tightened, and the connecting rod group 216 is converted from the combined state to the loose state again.
