[0001] The invention relates to the technical field of lightning protection for wind power generation equipment, in particular to an adjustable lightning arrester bracket for wind power generation equipment. Background Art
[0002] Lightning rods, or arresters, are important lightning protection devices. The basic operating principle of a typical lightning protection system on a wind turbine is to install a lightning rod on top of the generator, which is then connected to the buried ground grid via a compliant conductor. When lightning approaches the ground, the lightning rod distorts the electric field near the ground, creating an area of concentrated electric field at the tip of the rod. This area attracts the lightning leader and guides it to the lightning rod. The lightning current is then safely conducted to the earth via the down conductor and grounding device.
[0003] There is an obvious problem with the existing lightning rod design: they are usually fixed, which means that the lightning rod cannot be rotated or adjusted in angle.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it individually or selectively refer to an embodiment that is mutually exclusive of other embodiments.
[0036] Example 1
[0037] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides an adjustable lightning arrester bracket for wind power generation equipment, which includes a support body 100, including a support tube 101, a plurality of support columns 102 arranged in a circumferential array on the support tube 101, a lightning arrester assembly 103 arranged on one side of the support column 102, an adjustment base 104 arranged at the bottom of the support tube 101, and a limit ring 105 arranged on the support column 102;
[0038] The adjustment unit 200 includes an adjustment member 201, a transmission member 202 arranged on one side of the adjustment member 201, a steering assembly 203 arranged on one side of the transmission member 202, a grounding base 204 arranged on one side of the steering assembly 203, a transmission assembly 205 arranged on one side of the grounding base 204, a main needle 206 arranged on one side of the transmission assembly 205, and a plurality of groups of oblique needles 207 arranged in a circular array on the grounding base 204.
[0039] It should be noted that the support body 100 provides support for the entire lightning protection bracket. Among them, the support tube 101 is sleeved on the adjustment base 104, and the adjustment base 104 is fixedly installed on the wind turbine equipment to provide a stable support for the bracket structure above. Four groups of support columns 102 in a circular array are fixedly connected above the support tube 101, and gaps are left on the sides of the support columns 102 to facilitate the line connection of the lightning protection assembly 103. An adjustment base 104 is provided below the support tube 101, and the adjustment base 104 can control the up and down lifting and lowering of the support tube 101. Since the support tube 101 is hollow inside, it is sleeved on the adjustment base 104 without affecting its supporting function.
[0040] Preferably, the limiting ring 105 is fixedly connected to the top of the support column 102. The limiting ring 105 can drive the adjustment unit 200 to adjust the angle. Among them, the adjustment member 201 is limited inside the limiting ring 105, and the limiting ring 105 drives the adjustment member 201 under the action of the lifting and lowering of the support tube 101. The transmission member 202 connected to the adjustment member 201 passes through the inside of the support tube, and the transmission member 202 has a conductive function. The transmission member 202 can rotate in the horizontal direction, and the adjustment member 201 can rotate in the vertical direction. The two can cooperate to rotate the main needle 206 at the top in space, thereby realizing multi-directional protection of the fan.
[0041] Preferably, the steering assembly 203 is connected to the top limit of the transmission member 202. Driven by the transmission member 202, the steering assembly 203 can also be turned and rotated. A grounding base 204 is fixedly connected to the top of the adjustment member 201, and the upper layer of the grounding base 204 is electrically connected to the main needle 206, and the side is electrically connected to three groups of oblique needles 207. A group of transmission components 205 are threadedly connected to the outer layer of the main needle. Under the action of rotation, the transmission component 205 can adjust the angle of the oblique needle 207. This makes the lightning reception effect of the top more obvious. The angle between the main needle 206 and the oblique needle 207 can be adjusted according to weather conditions. In addition, the transmission component 205 also has a conductive function, so the transmission component 205 can act as a dynamic ring, thereby further improving the lightning reception capability.
[0042] Furthermore, the lightning protection assembly 103 includes two sets of fixed half rings 103a provided on one side of the support column 102, a plurality of circumferential arrays of mounting brackets 103b provided on the fixed half rings 103a, a single lightning arrester 103c provided on one side of the mounting brackets 103b, and a hinge 103d provided on the fixed half rings 103a;
[0043] The fixed half ring 103a has a plurality of groups of connection holes 103a-1 arranged in a circumferential array.
[0044] It should be noted that the lightning protection assembly 103 is arranged on the top side wall of the support tube 101, and plays a synergistic role with the main needle 206 and the oblique needle 207. Among them, the fixed half ring 103a clamps the support tube 101 under the clamping of the hinge 103d. A plurality of groups of connection holes 103a-1 are arranged in a circumferential array on the fixed half ring 103a, and the mounting bracket 103b is bolted to the connection hole 103a-1. A single lightning arrester 103c is installed on the upper and lower groups of mounting brackets 103b, wherein the grounding end of the single lightning arrester 103c is connected to the transmission member 202 through the line Q. Since the single lightning arrester 103c only reduces the amplitude of the overvoltage, the main needle 206 and the oblique needle 207 are connected in series with the single lightning arrester 103c, thereby reducing the risk of equipment damage and improving the lightning protection capability of the equipment.
[0045] During use, there are two situations: During normal use, the main needle 206 is in a vertical position, and the oblique needle 207 can rotate the transmission assembly 205 upward under the rotation of the transmission member 202, thereby pulling the oblique needle 207 closer to the position of the main needle 206, reducing the outer diameter of the lightning rod and improving the local lightning resistance capability, or increasing the outer diameter of the lightning rod and improving the lightning resistance range. When lightning is to be received in a certain direction, the adjustment base 104 can be activated to raise and lower the support tube 101, allowing the limit ring 105 to adjust the angle of the adjustment member 201, and further adjust the angles of the main needle 206 and oblique needle 207. This allows the lightning rod to rotate in a spatial range, thereby achieving multi-directional protection for the wind turbine.
[0046] In summary, this design realizes the adjustment of the angles of the main needle 206 and the oblique needle 207 on the wind turbine through the setting of the support body 100 and the adjustment unit 200, thereby expanding the protection range of the lightning rod and ensuring that the direction of connection between the lightning rod and lightning is consistent, thereby increasing the rate of power conduction and improving safety performance. At the same time, it can change the outer diameter of the main needle 206 and the oblique needle 207 to improve the local lightning protection capability, or expand the lightning protection range, and connect the main needle 206 and the oblique needle 207, as well as the single lightning arrester 103c in series, thereby further reducing the risk of equipment damage and improving the lightning protection capability of the equipment.

[0081] When adjusting the angle, the lifting drive disk 104e-1 is first driven to rotate. With the rotation of the bolt column 104e and the movement of the limiting rod 104d along the rod slot 104c to limit the rotation of the support tube 101, the support tube 101 is ensured to move upward under the threaded connection. The slide groove 105a at the top of the support tube 101 simultaneously drives the limiting ball head 201d upward. Under the hinged connection between the connecting rod 201c and the U-shaped connecting tube 202b, the connection tray 201a will shift its position angle, causing the main pin 206 and the oblique pin 207 on the top of the lightning arrester to deflect. When a horizontal direction change is required, the rotating drive disk 202a-2 is driven. The rotation of the transmission shaft 202a engages and rotates the connection tray 201a. The two cooperate to rotate the main pin 206 and the oblique pin 207 at the top, thereby achieving multi-directional protection for the wind turbine. When the transmission shaft 202a rotates, it will also drive the steering female head 203b to drive the spiral tube sleeve 206a to rotate, and the rotary bearing 205a can be rotated upward, thereby pulling the oblique needle 207 to continuously move closer to the position of the main needle 206, reducing the outer diameter of the lightning rod and improving the local lightning rod capacity, or increasing the outer diameter of the lightning rod and improving the lightning rod range; further adjust the angle of the main needle 206 and the oblique needle 207. The lightning rod equipment can be rotated in a spatial range, thereby achieving multi-directional protection for the wind turbine. In addition, the fixed half ring 103a is bolted to the support tube 101. When the support tube is raised or lowered, the lightning protection assembly 103 can be dynamically adjusted, further reducing the risk of equipment damage and improving the lightning protection capability of the equipment.
[0082] In summary, this design enables the angles of the lightning protection devices on the wind turbine, namely the main needle 206 and the oblique needle 207, to be flexibly adjusted by setting the supporting body 100 and the adjustment unit 200. It not only significantly expands the protection range of the lightning rod, but also ensures that the direction of connection between the lightning rod and the lightning is always consistent, thereby greatly improving the rate of power conduction and overall safety performance. In addition, while adjusting the angles of the main needle 206 and the oblique needle 207, the outer diameters of the main needle 206 and the oblique needle 207 can also be changed, which further enhances the local lightning protection capability or expands the lightning protection range. This flexibility enables the lightning protection device to better adapt to different environments and meteorological conditions, and improves its ability to respond to lightning. And the main needle 206 is connected in series with the oblique needle 207 and the single lightning arrester 103c. This connection method not only enhances the overall performance of the lightning protection system, but also further reduces the risk of equipment damage, thereby significantly improving the lightning protection capability of the equipment.
