The specific meaning of the above terms in embodiments of the present application will be understood in detail by those of ordinary skill in the art.
Referring to fig. 1-3, an embodiment of the present application provides a GIL tube flexible support device, comprising a flexible support 100; the flexible stent 100 includes an outer frame 110 and four constraining cords 120; the outer frame 110 is sleeved on the periphery of the GIL pipeline 200; the circumference of the GIL tube 200 is provided with connection rings 130 corresponding to the four constraint ropes 120 one by one; the four connection rings 130 are respectively disposed at four different angular directions of the GIL tube 200; the four constraint ropes 120 are respectively penetrated through the corresponding connecting rings 130, and two ends of the four constraint ropes 120 are connected with the outer frame 110; the four restraint ropes 120 are all arranged in the outer frame 110 in an arc shape, and the convex edges of the restraint ropes 120 face the GIL pipeline 200; the uppermost constraint strand 121 of the four constraint strands 120 has the largest radius of curvature and the lowermost constraint strand 123 has the smallest radius of curvature.
More specifically, the four connection rings 130 are preferably distributed in four directions of the GIL tube 200 at 90 ° intervals, respectively, so that the connection rings 130 installed in this way have the best vibration isolation effect on the GIL tube 200; the outer frame 110 is ring-shaped, and the arrangement of the four constraint ropes 120 can prevent the whole flexible support 100 from being separated from the GIL tube 200; the convex edges of the constraint ropes 120 face the GIL tubes 200, that is, the direction of the connecting line between the midpoint of the circular arc formed by the constraint ropes 120 and the center of the circle where the constraint ropes are located is the direction away from the GIL tubes 200. The uppermost restraint strand 121 bears the main vertical load of the GIL tube 200, so the uppermost restraint strand 120 has the greatest radius of curvature and the greatest vertical equivalent stiffness; the radius of curvature of the restraining ropes 122 at both sides is smaller than that of the restraining ropes 121 at the uppermost side, and the radius of curvature of the restraining ropes 122 at both sides is larger than that of the restraining ropes 123 at the lowermost side, for preventing the GIL tube 200 from being excessively displaced in the horizontal direction; the lowermost restraint strand 123 has a smaller radius of curvature for providing vertical friction damping to the GIL tube 200.
When the vibration isolation protection device is used, the four constraint ropes 120 can jointly form vibration isolation protection on the GIL pipeline 200 positioned in the middle, can play a vibration isolation protection role on the GIL pipeline 200 along the longitudinal direction, the transverse direction and the vertical direction, has a damping energy consumption effect, plays a role in reducing local sedimentation influence, is beneficial to reducing influence of external vibration on the GIL pipeline 200, effectively solves the technical problem that the conventional GIL pipeline 200 support cannot cope with transverse deformation and vertical deformation of the GIL pipeline 200, and has self-resetting capability to meet the installation requirement of the GIL pipeline 200.
Further, in the present embodiment, the outer frame 110 is specifically a square frame; four restraint lines 120 are respectively distributed at positions corresponding to four sides of the square frame. Compared with a round frame or other frames with other shapes, the square frame has more proper empty space inside, so that the four constraint ropes 120 are connected and fixed with the GIL pipeline 200 in an arc shape, and when the square frame is installed, the constraint ropes 120 are prestressed, so that the whole structure is more stable.
More specifically, the height of the square frame in the vertical direction is smaller than the width in the horizontal direction, so that four restraint ropes 120 having different curvatures are more conveniently distributed in the square frame.
Further, in the present embodiment, two ends of the uppermost constraint rope 121 of the four constraint ropes 120 are connected to parallel two sides of the square frame, respectively, and two ends of the remaining constraint ropes 120 are connected to corresponding sides of the square frame. That is, one end of the constraint line 121 positioned at the uppermost is connected to the left side of the square frame, and the other end is connected to the right side of the square frame; two ends of a left constraint rope in constraint ropes 122 positioned at two sides are connected with the left side of the square frame, and two ends of a right constraint rope are connected with the right side of the square frame; both ends of the constraint line 123 located at the lowermost position are connected to the bottom edge of the square frame, so that the installation requirement of the constraint line 121 located at the uppermost position with the largest radius of curvature can be satisfied.
Further, in the present embodiment, both ends of the uppermost one 121 of the four restraint ropes 120 are respectively in contact with and abut against the two restraint ropes 120 located on both sides of the outer frame 110. This arrangement can appropriately improve the bearing capacity of the restraint ropes 121 located at the uppermost position, and does not affect the deformation isolation of the restraint ropes 122 located at the both sides because there is a gap between the restraint ropes 122 located at the both sides and the restraint ropes 123 located at the lowermost position.
Further, in the present embodiment, two restraint ropes 122 located at both sides of the outer frame 110 are symmetrically disposed. The restraining ropes 122 disposed at both sides in this way can provide the optimal vibration isolation protection effect to the GIL tube 200 in the lateral direction.
Further, in the present embodiment, the number of flexible stents 100 is plural, and the plurality of flexible stents 100 are uniformly distributed along the length direction of the GIL tube 200. By the arrangement, the whole GIL pipeline 200 can be guaranteed to have good vibration isolation and protection effects everywhere, and the influence of external vibration on the GIL pipeline 200 is greatly reduced.
Further, in the present embodiment, the distance between adjacent two flexible brackets 100 is 10m to 15m. By disposing the flexible brackets 100 between the appropriate distances on the GIL tubes 200, the cost required for vibration isolation of the GIL tubes 200 can be effectively reduced while not affecting good vibration isolation of the GIL tubes 200.
Further, in the present embodiment, both ends of each of the restraint ropes 120 are adjustably connected to the outer frame 110 through the fixed adjuster 140. The length of each restraint rope 120 in the outer frame 110 can be adjusted according to actual requirements by the fixed adjusters 140, so that the four restraint ropes 120 are suitable for vibration isolation protection of GIL pipelines 200 with different sizes, and the application range of the whole device is greatly expanded.
Further, in this embodiment, each of the restraint cords 120 is formed from a plurality of wire ropes wound together. The restraint rope 120 composed of the steel wire rope is low in manufacturing cost, convenient to install and good in durability due to the fact that stainless steel is adopted.
Further, in the present embodiment, the relationship between the rigidity of each connecting ring 130 and the curvature radius and arc length angle of the corresponding restraining rope 120 is:
Where k is the stiffness of the connecting ring 130, R is the radius of curvature of the constraint rope 120, θ is the arc length angle of the constraint rope 120, EI is the bending stiffness of the wire rope, E is the elastic modulus of the wire rope making up the constraint rope 120, and d is the total diameter of the multiple strands of wire ropes making up the constraint rope 120.
Referring to fig. 2, the arc length angle of the constraint rope 120, that is, the central angle of the arc where it is located, is the rigidity of the connection ring 130 along the direction a; when the rigidity required by the GIL tube 200 at the connection ring 130 is known through multiple tests, the bending rigidity of the steel wire rope can be calculated through the measurable numerical value, so that the constraint condition between the curvature radius of the constraint rope 120 and the arc length angle of the constraint rope 120 required by the connection ring 130 can be calculated through the formula, and the staff can better adjust the length of the constraint rope 120 in the outer frame 110 according to the actual situation.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application.
