Detailed Implementation

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Example:

[0025] like Figures 1-2 As shown, a polyurethane composite tower with a reinforcing layer includes a tower body and a reinforcing layer. The tower body includes tower segments 10 of polyurethane composite material connected sequentially at their upper ends in the vertical direction. The reinforcing layer includes an upper connecting block 21, a lower connecting block 22, a transition block 23, and a first reinforcing column 24, wherein the upper connecting block 21, the lower connecting block 22, and the transition block 23 are all cylindrical. The upper connecting block 21 is located at the top inner side of the tower segment 10, the lower connecting block 22 is located at the bottom inner side of the tower segment 10, and the transition block 23 is located at the middle inner side of the tower segment 10. The upper connecting block 21, the lower connecting block 22, and the first reinforcing column 24 can be arbitrarily... The inner wall of the tower section 10 is connected by a detachable connection method; the bottom side of the upper connecting block 21 is provided with a first slot in a ring array, the transition block 23 is provided with a through hole 231 in the axial direction corresponding to the first slot, and the top side block of the lower connection is provided with a second slot corresponding to the first slot; the through hole 231 is adapted to the middle part of the first reinforcing column 24, and the first slot and the second slot are adapted to the two ends of the first reinforcing column 24 respectively; the first reinforcing column 24 can be made of steel bar, the middle part of which passes through the through hole 231, and the two ends are respectively inserted into the first slot and the second slot, so that the first reinforcing column 24 is arranged vertically in a ring array between the upper connecting block 21 and the lower connecting block 22.

[0026] The working principle of the above technical solution is as follows:

[0027] The upper connecting block 21, the lower connecting block 22, and the transition block 23 reinforce the ends and middle of the tower segment 10, making the ends and middle of the tower segment 10 less prone to deformation. The first reinforcing column 24 in the ring array between the two can strengthen the entire tower segment 10, making it less prone to bending under wind force. The first reinforcing column 24 has a more stable structure under the support of the transition block 23, making both the tower segment 10 itself and the first reinforcing column 24 less prone to deformation.

[0028] In another embodiment, such as Figure 1-2As shown, the top outer side, middle outer side and bottom outer side of the tower section 10 are respectively provided with a first reinforcing sleeve 31, a second reinforcing sleeve 32 and a third reinforcing sleeve 33; a first bolt penetrating the tower section 10 is provided between the first reinforcing sleeve 31 and the upper connecting block 21, a second bolt penetrating the tower section 10 is provided between the second reinforcing sleeve 32 and the transition block 23, and a third bolt penetrating the tower section 10 is provided between the third reinforcing sleeve 33 and the lower connecting block 22.

[0029] When installing the first reinforcing sleeve 31, the second reinforcing sleeve 32, and the third reinforcing sleeve 33, first align the corresponding upper connecting block 21, lower connecting block 22, and transition block 23 from the outside of the tower section 10. Then, drill axial holes from the outside of the first reinforcing sleeve 31, the second reinforcing sleeve 32, and the third reinforcing sleeve 33, respectively, penetrating the sidewalls of the upper connecting block 21, the lower connecting block 22, and the transition block 23. The penetration points do not interfere with the locations of the first slot, the second slot, and the through hole 231. Finally, connect them using the first bolt, the second bolt, and the third bolt. The bolted connections can be reinforced by welding. The first reinforcing sleeve 31, the second reinforcing sleeve 32, and the third reinforcing sleeve 33 can further strengthen the tower section 10, and the reinforcing layer is a modular structure, which facilitates assembly and individual replacement of parts of the structure. This is beneficial for installation, transportation, and reducing production costs.

[0030] In another embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, a plug-in sleeve 40 is provided between two adjacent tower sections 10. The plug-in sleeve 40 is cylindrical, and a connecting ring 41 is provided in the middle of the outer side. The end of the tower section 10 is sleeved on the outside of the plug-in sleeve 40 and abuts against the top and bottom sides of the connecting ring 41 respectively. Support rings 42 are provided at the top and bottom of the inner side of the plug-in sleeve 40 respectively. A third slot is opened on the top side of the upper connecting block 21, and a fourth slot is opened on the bottom side of the lower connecting block 22. The lower connecting block 22 at the higher position and the lower connecting block 22 at the lower position of the two adjacent tower sections 10 are connected. A second reinforcing column 50 is provided between the upper connecting sections. The two ends of the second reinforcing column 50 are respectively inserted into the third slot and the fourth slot. The support ring 42 is provided with a support hole 421 for sleeve of the second reinforcing column 50, so that the support ring 42 can support and limit the second reinforcing column 50 at two points in the middle, and the second reinforcing column 50 is not easily deformed. A fourth reinforcing sleeve 60 is also provided on the outer side of the ends of two adjacent tower sections 10. A fourth bolt penetrating the tower section 10 is provided between the fourth reinforcing sleeve 60 and the insertion sleeve 40.

[0031] The plug-in sleeve 40, the second reinforcing column 50 and the fourth reinforcing sleeve 60 further strengthen the connection of tower section 10 and improve the connection stability between tower sections 10.
