Description

Technical Field

[0001] This utility model relates to the technical field of wind farm substation collector line towers, specifically a wind-resistant wind farm substation collector line tower. Background Technology

[0002] The primary function of the collector lines in a wind farm substation is to collect the electricity generated by multiple wind turbines and transmit it to the substation. This process ensures the effective collection and transmission of electricity, providing a foundation for long-distance power transmission and distribution. Therefore, the design and construction of collector line structures must consider factors such as topography and environmental impact to ensure stable power transmission and reliable supply. However, most wind farm substation collector line towers are quite tall, making the tops susceptible to significant wind force. This can cause the towers to sway during operation, potentially leading to tilting after installation and posing a significant safety hazard.

[0003] To address this, Chinese utility model patents CN202022531778.9 and CN202320343342.8 both disclose a wind-resistant power transmission tower. The former adds a reinforcing support rod around the bottom of the power transmission tower to improve its structural stability and ensure wind resistance; the latter adds a protective frame to the outside of the power transmission tower, making the frame an integral part of the tower, thus improving the structural strength and wind resistance of the main body and preventing deformation and collapse. In summary, existing technologies all rely on adding extra structures to ensure wind resistance, which has certain drawbacks: 1. The redundant mechanical structure increases the erection cost of the power transmission tower, hindering maintenance companies from saving expenses; 2. It increases the self-weight of the power transmission tower, posing a risk of settlement and collapse if the tower is installed on soft soil layers such as silty clay. Utility Model Content

[0004] The purpose of this utility model is to disclose a wind-resistant wind farm substation collector tower to solve the drawbacks of the above-mentioned power towers, such as heavy weight and high erection cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wind-resistant wind farm substation collector tower includes a load-bearing foundation, to which the tower body is fixedly connected. The tower body consists of a base, tower sections, and a tower tip from bottom to top. Multiple anchor points are provided on the inner side of the base, which are staggered vertically within 1 / 2 to 2 / 3 of the base height. Each anchor point is connected to a steel cable, the other end of which is connected to a counterweight fixed to the load-bearing foundation. The counterweight is located on the central axis of the base. There are multiple tower sections, and each section has reinforcing braces arranged crosswise inside. From bottom to top, every odd-numbered tower section has a crossarm fixed on both sides, and a reflective bird deterrent is fixed on the crossarm. The tower tip is fixed on the topmost tower section, and a lightning rod is fixed to the top of the tower tip.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] Without increasing the construction cost of a single tower, the structural strength and deformation resistance of the tower were improved by simply using anchor cables fixed to the ground counterweight and reinforcing braces. This enhanced the wind resistance of the tower body and prevented the tower body from deforming and collapsing. Attached Figure Description

[0011] The present invention will be further explained below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, a wind-resistant wind farm substation collector tower includes a support foundation 2, on which a tower body 1 is fixed. The tower body 1 consists of a tower base 7, tower sections 8, and a tower tip 9 from bottom to top. Multiple anchor points 10 are provided on the inner side of the tower base 7. These anchor points 10 are staggered vertically within the range of 1 / 2 to 2 / 3 of the tower base height, and each anchor point 10 is connected to a steel cable 11. The other end of the steel cable 11 is connected to a counterweight 6 fixed on the support foundation 2. The counterweight 6 is located on the central axis of the tower base 7. There are multiple tower sections 8, and each tower section 8 has reinforcing braces 12 arranged crosswise inside. From bottom to top, every odd-numbered tower section 8 has a hanging crossarm 3 fixed on both sides, and a reflective bird deterrent 4 is fixed on the hanging crossarm 3. The tower tip 9 is fixed on the topmost tower section 8, and a lightning rod 5 and a height warning light 13 are fixed on the tower tip 9.

[0013] During the installation of this utility model tower, firstly, a reinforced concrete bearing foundation 2 and a counterweight 6 are poured on the ground to be installed according to the dimensions of the tower base 7, ensuring that the counterweight 6 is located on the central axis of the tower base 7 after installation. After the tower base 7 is installed, tower sections 8 with reinforcing supports 12 are fixed on the tower base 7 according to the height set in the process. On the left and right sides of the odd-numbered tower sections 8, hanging crossarms 3 with reflective bird deterrents 4 are installed, ensuring that the central axis of the tower section 8 coincides with the tower base 7. Finally, the tower tip 9 is installed, ensuring that the central axis of the tower tip 9 coincides with the central axis of the tower section 8, and a lightning rod 5 and a height warning light 13 are installed on the tower tip 9. After all installations are checked and confirmed to be correct, the tower base 7 and the counterweight 6 are connected using steel cables 11, and after tensioning and locking, it can be put into use.

[0014] This invention utilizes a few simple steel cables and reinforcing supports to improve the structural strength and deformation resistance of the tower without significantly increasing construction costs and weight. This meets the wind deformation resistance requirements of wind farm collector towers in the arid northwest region, preventing the tower body from deforming and collapsing. Simultaneously, by installing a reflective bird deterrent, which rotates using natural airflow, the reflective material reflects light to drive away birds approaching the tower body. This prevents birds from perching on the tower body, protects it from bird droppings corrosion, and reduces the tower's failure rate.
