Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See Figures 1-5 This utility model provides the following two technical solutions:

[0026] First embodiment: A vortex-induced vibration suppression device for marine engineering includes a riser 1, which is connected to a suppression component for suppressing vortex-induced vibration. The suppression component includes: two sets of limiting components 2, which are respectively disposed on the riser 1 to limit the suppression end. The limiting component 2 includes two sets of protective sleeves 21 that are slidably connected to the riser 1. Several collars 22 are provided on the outer side of the middle part of the protective sleeves 21, and straps 23 are slidably connected in the several collars 22; and an installation pipe assembly 3, which is disposed on the riser 1 and located between the two sets of limiting components 2. The installation pipe assembly 3 includes a pipe body 31 that is slidably connected to the outer side of the riser 1. A stop block 34 that is slidably connected to the riser 1 is provided at the bottom of the pipe body 31. Several locking grooves 33 are provided on both sides of the pipe body 31.

[0027] The fairing assembly 4 is disposed outside the mounting tube assembly 3 for rectification. The fairing assembly 4 includes two sets of housings 41 that fit together. The inner sides of the two sets of housings 41 are provided with an array of guide strips 44 that are slidably connected to the locking grooves 33. The middle adjacent ends of the two sets of housings 41 are provided with connecting grooves 43. The end of the housing 41 near the connecting grooves 43 is provided with an array of screws 45. The anti-detachment plate 5 is installed inside the two sets of adjacent housings 41 and connected to the screws 45. The limiting member 2 also includes a locking assembly 24 installed on the collar 22 for locking. The protective sleeve 21 is provided with a sliding groove that is slidably connected to the strap 23. The strap 23 is made of stainless steel. The bottom of the stop block 34 fits against the upper side of a set of protective sleeves 21. The inner wall of the stop block 34 is provided with a circular groove that is slidably connected to the riser 1. The mounting tube assembly 3 also includes an array of locking holes 32 disposed on the tube body 31 and matched with the screws 45.

[0028] The fairing assembly 4 also includes an array of vortex grooves 42 disposed on the side of the cover 41. The anti-detachment plate 5 is slidably connected in two sets of connecting grooves 43 and threadedly connected to several screws 45. The top of the anti-detachment plate 5 fits against the bottom of a set of protective sleeves 21. The two sets of covers 41 are combined into a streamlined shape. The tube body 31, locking hole 32, locking groove 33, stop block 34, guide strip 44, screw 45, and anti-detachment plate 5 cooperate with each other, which facilitates the quick and accurate installation of the two sets of covers 41 on the tube body 31. It has an anti-detachment function and is easy to disassemble.

[0029] The main difference between the second implementation method and the first implementation method is that:

[0030] The guide strip 44 has an anti-detachment strip that slides with the locking groove 33. The protective sleeve 21 and the cover 41 are both made of HMPE material. The suppressing component also includes an array of bolt assemblies 6 installed on both sides of the two sets of covers 41. The bolt assemblies 6 and screws 45 are both made of stainless steel. The bolt assemblies 6 are used for the tight fit of the two sets of covers 41. The anti-detachment strip cooperates with the guide strip 44 and the locking groove 33 to prevent the cover 41 from detaching during the docking process with the tube body 31.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user places a set of limiting pieces 2 on the outside of the riser 1. When the limiting pieces 2 are at a suitable height on the riser 1, the user pulls the strap 23 to fix the protective sleeve 21 on the riser 1. The strap 23 is then locked by the locking assembly 24. The pipe body 31 is then placed on the upper side of the riser 1. The pipe body 31 and the stop block 34 slide down the upper side of the riser 1. The slide stops when the stop block 34 contacts the protective sleeve 21. The two sets of cover 41 are then connected to the pipe body 31 by inserting the array of guide strips 44 into the locking grooves 33 on the outer surface of the pipe body 31. At this time, the two sets of cover 41 fit together. Furthermore, the cover is installed on the outside of the tube body 31, allowing the anti-detachment plate 5 to be inserted into the connecting groove 43 at the adjacent ends of the two sets of covers 41. The covers 41, the anti-detachment plate 5, and the tube body 31 are respectively threaded together by an array of screws 45. The array of bolts 6 locks the edge ends of the two sets of covers 41. Another set of limiting members 2 is fitted on the outside of the riser 1 and limits the upper end of the fairing assembly 4. The fairing assembly 4 is streamlined in shape and reduces the resistance and pulse lift of the riser 1 through several vortex grooves 42, thereby continuously vortex excitation. This is the existing technology, so its specific principle will not be described in detail.
