Detailed Description

In order to better understand the aspects of the present utility model, the present utility model will be described in further detail with reference to the accompanying drawings and detailed description.

According to an embodiment of the present utility model, there is provided a supporting device. As shown in fig. 1, the support device comprises a support column 1, a foundation pile 2, and a transition section 3. The photovoltaic panel is mounted on brackets (not shown in the figures), each of which is provided with a plurality of bracket posts 1. In the process of hoisting, a plurality of support columns 1 and a plurality of foundation piles 2 need to be aligned one by one and fixedly connected. The foundation pile 2 is, for example, a PHC (theprestressed high-intensity concrete prestressed high strength concrete) pile. The bottom of foundation pile 2 buries in the seabed, and the top of foundation pile 2 is used for being connected with support post 1. The transition section part 3 is arranged between the foundation pile 2 and the support column 1, the transition section part 3 comprises a body part 33 and at least one flange plate perpendicular to the body part 33, a round hole or a waist hole is formed in the flange plate, the central line of the waist hole extends along the circumferential direction of the flange plate, at least one of the support column 1 and the foundation pile 2 is provided with a waist hole corresponding to the round hole of the corresponding flange plate, or a round hole corresponding to the waist hole of the flange plate is formed, and a connecting bolt is arranged between the waist hole and the corresponding round hole.

At least one flange plate is arranged through the transition section part, waist holes or round holes are formed in the flange plate, round holes corresponding to the waist holes of the flange plate or waist holes corresponding to the round holes of the flange plate are formed in at least one of the foundation pile 2 or the support column 1, errors in mounting the foundation pile 2 are made up through the cooperation mode between the waist holes and the round holes, and the support column 1 can be abutted to the foundation pile through the transition section part 3.

In one example, the at least one flange provided at the transition section 3 includes a first flange and a second flange, and the second flange 32 is vertically provided at an end of the body portion 33 remote from the first flange 31.

As shown in fig. 2, a plurality of first round holes 21 are formed in the top end of the foundation pile 2. The plurality of first round holes 21 are uniformly distributed along the circumferential direction of the top end face of the foundation pile 2.

As shown in fig. 1, the foundation pile 2 is arranged coaxially with the transition section 3. The transition section 3 comprises a body portion 33 and a first flange 31 arranged perpendicularly to the body portion 33. The body portion 33 is of cylindrical configuration. The first flange 31 is connected to the foundation pile 2. For example, the radial dimension of the first flange 31 matches the radial dimension of the foundation pile 2.

Referring to fig. 3, the first flange 31 is provided with a plurality of first waist holes 311 circumferentially spaced apart. For example, the first waist hole 311 is a long circular arc hole. The first waist hole 311 penetrates the first flange 31 in the vertical direction. The center line of the first waist hole 311 extends in the circumferential direction of the first flange 31. The center line of the first waist hole 311 is the connecting line between the centers of the semicircular parts at the two ends of the waist hole. The extending direction of the center line of the first waist hole 311 coincides with the circumferential direction of the first flange 31.

The first round hole 21 and the corresponding first waist hole 311 are internally provided with connecting bolts, and the connecting bolts can be internally arranged in the first round hole 21 and the first waist hole 311 so as to form connection between the transition section 3 and the foundation pile 2. The inner diameter of the first circular hole 21 corresponds to the aperture of the first waist hole 311. The inner diameter of the first round hole 21 is the diameter of the first round hole 21, and the aperture of the first waist hole 311 is the diameter of the semicircular parts at the two ends of the first waist hole 311, that is, the width of the first waist hole 311.

For example, as shown in fig. 4, the first round hole 21 and the first waist hole 311 are bolt holes, and an internal thread structure adapted to an external thread structure of an outer wall of a bolt is provided on a wall of the first round hole 21 and the first waist hole 311. It can be understood that the first round hole 21 and the first waist hole 311 are bolt through holes, and no screw thread structure is arranged on the hole wall of the bolt through holes, but only the bolt through holes are used for passing through the bolts.

During hoisting, it is often necessary to dock and fix a plurality of support posts 1 with foundation piles 2. When the foundation pile 2 is installed, due to the influence of the offshore operation environment, the foundation pile 2 rotates to a certain extent during piling, and in order to compensate for the deflection of the angle of the foundation pile 2 during installation, a first waist hole 311 is formed in the first flange 31 of the transition section 3, and the first waist hole 311 extends along the circumferential direction.

The first round hole 21 is formed in the top end of the foundation pile 2, and the first round hole 21 can still be positioned in the extending range of the first waist hole 311 corresponding to the first round hole 21 when the foundation pile 2 deflects circumferentially at an angle in a mode of matching the first round hole 21 with the first waist hole 311.

In this way, the transition section 3 is able to compensate for the angle of deflection of the foundation pile 2 in the circumferential direction. The situation that a plurality of support columns 1 cannot be all aligned and fixed with the foundation piles 2 when the support columns 1 are directly connected with the foundation piles 2 is avoided.

As shown in fig. 3, the transition section 3 includes a first reinforcing beam 4. The first reinforcing beam 4 is disposed between the body portion 33 and the first flange 31 in the vertical direction. The side edges of the first reinforcing beam 4 in the vertical direction are fixed to the side surfaces of the body portion 33, and the bottom end of the first reinforcing beam 4 is fixed to the end face of the first flange 31, which is far from the foundation pile 2. The plurality of first reinforcing beams 4 are arranged at intervals along the circumferential direction of the first flange 31, and one first waist hole 311 is arranged between two adjacent first reinforcing beams 4. In this way, the structural strength of the transition piece portion 3 can be improved, and the first waist hole 311 does not damage the structure of the first flange 31.

As shown in fig. 4, the first circular hole 21 provided at the top end of the foundation pile 2 is located between two adjacent first reinforcing beams 4 in the projection range of the first flange 31. For example, two first round holes 21 may be provided between adjacent first reinforcing beams 4.

In the embodiment of the present utility model, the transition section 3 further includes a second flange 32, and the second flange 32 is vertically disposed at an end of the body portion 33 remote from the first flange 31. The second flange 32 is fixedly connected to the body 33, and the second flange 32 is disposed in a horizontal direction and perpendicular to the support column 1. For example, the end of the support column 1 connected to the second flange 32 is also in a flange structure.

As shown in fig. 6, the second flange 32 is provided with second circular holes 321 circumferentially spaced apart. The bottom of the support column 1 is provided with a second waist hole 11, and bolts are arranged in the second round hole 321 and the second waist hole 11. The second waist hole 11 extends in the circumferential direction of the second flange plate 32. The second circular hole 321 has an inner diameter larger than that of the second waist hole 11. The second waist hole 11 has a smaller aperture than the second round hole 321. The aperture of the second waist hole 11 is the radial dimension of the second waist hole 11 in the second flange 32.

By arranging the second round hole 321 in the transition section 3 and matching with the second waist hole 11, the error of the foundation pile 2 in the water direction during piling can be compensated. Meanwhile, the second waist hole 11 provided on the bracket post 1 can compensate for a slight error in mounting the transition section 3.

In one embodiment, as shown in fig. 10, the transition section 3 includes a hollow 34, the hollow 34 extending in the axial direction of the transition section 3. The body portion 33 of the transition section is hollow, tubular in configuration. A limiting column 12 extends from the bottom end of the support column 1 towards the transition section 3, and the limiting column 12 can extend into the transition section 3 in the vertical direction.

For example, when aligning the plurality of support columns 1 and the plurality of foundation piles 2 of the entire photovoltaic panel support, the positioning is performed by inserting the stopper columns 12 into the transition section. In addition, the transition section and the foundation pile 2 can provide temporary supporting devices for the support columns 1, so that the safety during hoisting is improved.

In one example, as shown in fig. 5 and 11, the transition section 3 further comprises at least one bolt spacer 35, the bolt spacer 35 being arranged between the second flange plate 32 and the bracket post 1. The mounting assembly further comprises a plurality of bolt gaskets 35, and the plurality of bolt gaskets 35 are arranged in a stacked mode to adjust the overall height of the mounting assembly. In this way, the height of the foundation pile 2 in the vertical direction can be compensated for.

Through the mode of matching between the first flange plate 31, the second flange plate 32, the foundation pile 2 and the bracket column 1, the rotation error, the horizontal error and the vertical error of the foundation pile 2 in the installation process can be effectively compensated.

After piling is completed, the transition section 3 is aligned with the foundation pile 2 as in fig. 9. By adjusting the first waist hole 311 and the first round hole 21, the transition section 3 is adjusted to match the error of the circumferential rotation angle of the foundation pile 2. As further shown in fig. 10, the stopper posts 12 (for example, insertion tips) of the plurality of support posts 1 of the group of photovoltaic modules are inserted into the hollow portion 34 of the transition piece portion 3. At the same time, as shown in fig. 11, the height of the installation assembly in the vertical direction is adjusted by adding the bolt spacer 35 so that the height between each foundation pile 2 and the bracket column 1 is uniform.

As shown in fig. 2, 14 first round holes 21 are uniformly formed in the circumferential direction of the top end surface of the foundation pile 2, and an angle α1 between a line L1 between a midpoint between the centers of the two first round holes 21 and a center point a of the horizontal cross section of the foundation pile 2 and a line L2 formed by the center of the first round hole 21 and the center point a of the foundation pile 2 is 12.857 °.
