The arrangement of the notch can be said to realize the tight contact between the tower section flanges of different sections without affecting the normal connection function of the flanges.
As shown in fig. 4, in the present embodiment, three sets of wind power generation blades include nine blade bodies 3 in total. The blade body 3 includes a blade plate 31, a skin 32 and She Gujia disposed therebetween, and the blade plate, the skin and She Gujia are all made of metal materials. Wherein the blades 31 are of planar construction, preferably sandwich panels. An arc structure is formed between the skin and the blade skeleton, the blade plate extends outwards along the arc structure, the extending part is not covered by the skin and She Gujia, and the flat structure of the blade plate is still maintained, so that the blade body integrally forms the arc section 33 and the plane section 34 through the design of the blade plate 31, the skin 32 and the blade skeleton. When two blade bodies 3 stack from top to bottom, the arc section 33 of first blade body back-off is in the planar section 34 of second blade body, and the arc section of first blade body is relative with the planar section of second blade body promptly, and the planar section of first blade body is relative with the arc section of second blade body simultaneously for the upper and lower face that forms after two blade bodies stack from top to bottom is the horizontal plane, thereby practice thrift the transportation space greatly.
Wherein She Gujia is disposed along the length direction of the blade body 3, is wrapped by the skin, and is gradually reduced in height from one end to the other end, that is, the arc section 33 is the largest at one end of the blade body 3 and the arc section is the smallest at the other end.
In this embodiment, the transportation end frame 2 includes a longitudinal column 21 and a cross beam 22 disposed between the longitudinal columns, a portion of the upper end of the longitudinal column extends along the cross beam, a top corner piece 23 is disposed at the end of the portion extending, a bottom corner piece 24 is disposed on the bottom surface of the longitudinal column, two diagonal rods 25 between the longitudinal column and the cross beam, the two diagonal rods 25 form an x-shaped structure, the lower end of the diagonal rods is connected with the lower cross beam, and the upper end of the diagonal rods is connected with the two longitudinal columns 21, so that on one hand, a reinforcing effect is achieved, on the other hand, a wind power tower can be supported or connected, and shaking of the wind power tower can be prevented. A certain interval is arranged between the diagonal rod 25 and the upper cross beam, and a certain interval is also arranged between the upper cross beam and the top corner piece 23, so that the diagonal rod can be used for placing a plurality of blade bodies.
As shown in fig. 5, the container type combination method of the wind power generation blades and the towers comprises the following steps of sequentially sleeving six sections 10 of each set of wind power generation tower 1 according to the size, stacking a plurality of blade bodies 3 up and down, wherein the upper surface and the lower surface formed by stacking the blade bodies up and down are horizontal surfaces, stacking the blade bodies and the lower surface and then placing the blade bodies on the upper part of the wind power generation tower 1 to form a transportation main body, arranging transportation end frames 2 at the front end and the rear end of the transportation main body, arranging one blade body 3 on two side surfaces of the transportation main body to serve as side plates of the transportation main body, and connecting the main body to be transported, the transportation end frames and the side plates to form a container structure for integral transportation.
Specifically, three sets of wind power towers 1 are arranged, six sections of tower sections 10 are sleeved in each set, the three sets of wind power towers can be connected into a whole through flanges 14 so as to prevent shaking during transportation, and the three sets of wind power towers can be arranged in the middle in the opposite directions with the wind power towers on two sides of the middle so as to facilitate alignment connection between the flanges. It can be understood that three sets of power generation tower sections can be placed in any direction, are arranged side by side along the length direction, and after being placed, the length direction of the three sets of power generation tower sections does not exceed the transportation size of the container.
The blade body 3 is arranged above the three sets of wind power towers 1. Because the total of nine blade bodies 3 in the embodiment is nine, seven wind power blades 3 are preferably placed above the wind power tower 1, wherein six wind power blades 3 are stacked in pairs, so that the upper surface and the lower surface formed by stacking two blade bodies up and down are horizontal surfaces. For example, in this embodiment, wind power blades stacked in pairs are referred to as blade stacking units, then three sets of blade stacking units are placed above the wind power tower, and then one blade body is singly placed above the three sets of blade stacking units, so that arrangement of seven wind power blades is completed, and each two adjacent sets of blade stacking units are reversely arranged, for example, the arrangement directions of the first set and the third set are the same, the end with the largest arc section is oppositely arranged, the end with the smallest arc section is oppositely arranged with the end with the largest arc section of the other two sets, and the uppermost blade body and the adjacent set of blade stacking units are reversely arranged. The arrangement mode of the invention can greatly improve the stacking compactness between the blades and shorten the height space.
After the arrangement is finished, the seven blade bodies 3 and the three sets of wind power towers 1 form a transportation main body, and the two sides of the transportation main body are provided with side plates to form a container transportation mode, so that the left two blade bodies 3 are used as the side plates, and the horizontal planes of the blade plates 31 of the blade bodies are outwards arranged to ensure the flatness of the outside, so that the container transportation standard is met. Like this, just formed the container structure between transportation end frame, curb plate and the transportation main part, and set up through the corner fitting on the transportation end frame 2 for whole satisfying the container transportation size, can realize sea and land transportation with the form of container, improve the convenience and the conveying efficiency of transportation greatly.
It is understood that the transportation end frame, the side plates and the transportation main body can be connected in various ways to be transported integrally, so that shaking and falling are prevented. For example, the side plates and the end frames, the transportation main body and the end frames are connected by bolts. The present invention is not particularly limited to the connection method.
In summary, the wind power tower and the blade body are designed to be stacked and assembled in the most compact mode, so that the space utilization rate can be greatly improved, sea and land transportation in a container mode is realized, and on the other hand, a plurality of sets of wind power towers and wind power generation blades can be transported at one time through reasonable space layout of tower sections and wind power blades, so that the wind power towers and the wind power generation blades are prevented from being transported repeatedly, and the transportation efficiency is greatly improved.
