Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
With reference to Fig. 1, Fig. 2 and Fig. 3, the schematic diagram of the protective device that Fig. 1 provides for first embodiment of the invention; Fig. 2 is the view along A-A line in Fig. 1; Fig. 3 is the view along B-B line in Fig. 1.
In the first embodiment of the present invention, protective device comprises at least two between the upper and lower every the guard circle 3 laid, and this guard circle 3 is for being set in the periphery of the support column 2 of marine brace table.Protective device also comprises the first linking arm 4 be connected between guard circle 3.
The quantity and spacing of guard circle 3 can be determined according to the size of the Wave energy in actual marine site, as the comparatively large quantity then increasing guard circle 3 of seaway load of this marine site whole year, to reduce Wave energy better.Particularly, in the present embodiment, the quantity of guard circle 3 is three, and the diameter of guard circle 3 can be identical, and three guard circles 3 are concentricity between the upper and lower every layout.Two or four can certainly be selected.
The protective device that the present embodiment provides; guard circle 3 can be set in the periphery of the support column 2 of marine brace table; interacted by guard circle 3 and wave; change the characteristics of motion of water particle; thus significantly reduce the height of wave; reduce the energy of wave, and then can seaway load intensity on the support column 2 of weakening effect at sea brace table, improve the stability of marine brace table and the safety of running of wind generating set.
It should be noted that, on the basis of above-mentioned first embodiment, can also be improved further protective device.
In spaced apart guard circle 3, the diameter of guard circle 3 from top to bottom increases successively.Setting that guard circle 3 is concentricity.That is, have vertical interval and level interval between two-layer guard circle 3, according to Wave Theory, said structure can weaken Wave energy in the horizontal direction, improves the stability of marine brace table and the safety of running of wind generating set.
Further, as described in Figure 4, aerofoil profile 31 can be made in the cross section of guard circle 3, the outer portion of guard circle 3 is lower than the internal ring portion of guard circle 3.The cross section of guard circle 3 adopts aerofoil profile 31; the resistance of guard circle 3 can be reduced; improve the effect weakening Wave energy; and because the outer portion of guard circle 3 is lower than the internal ring portion of guard circle 3; namely the sectional tool of guard circle 3 has downward angle; according to fluid dynamic theory, said structure can produce pressure straight down under the effect of current, and then can improve the stability of marine brace table further.
In addition, in order to improve the integral rigidity of protective device further, protective device also comprises center endless tube 5 and reinforcement arm 6; Center endless tube 5 is positioned at guard circle 3 and concentricity with guard circle 3, and one end of reinforcement arm 6 is connected with guard circle 3, and the other end of reinforcement arm 6 is connected with center endless tube 5.Further, reinforcement arm 6 is elliptical tube, and the longer axis parallel in the cross section of elliptical tube is in horizontal plane, and the namely flat setting of reinforcement arm 6, reinforcement arm 6 adopts elliptical tube can be convenient to weld with guard circle 3, and flat setting of reinforcement arm 6 can reduce resistance.
Equally as Figure 1-3; the embodiment of the present invention also provides a kind of marine brace table; comprise plummer 1 and support column 2; the upper end of support column 2 is connected with plummer 1; the lower end of support column 2 is for inserting in sea bed; this marine brace table also comprises the protective device described in above-described embodiment, and the guard circle 3 of protective device is connected with support column 2.This marine brace table also comprises the second linking arm 7; Second linking arm 7 is connected between guard circle 3 and described support column 2.
Further, the second linking arm 7 is elliptical tube, and the longer axis parallel in the cross section of elliptical tube is in horizontal plane.
The marine brace table that the present embodiment provides; guard circle 3 can be set in the periphery of the support column 2 of marine brace table; interacted by guard circle 3 and wave; change the characteristics of motion of water particle; thus significantly reduce the height of wave; reduce the energy of wave, and then can seaway load intensity on the support column 2 of weakening effect at sea brace table, improve the stability of marine brace table and the safety of running of wind generating set.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
