[0002] Wind power generation is the process of converting wind energy into electrical energy. Huge wind turbine blades rotate under the wind, driving the internal generator to generate electricity. Since wind turbines are usually erected in open, high places, they are susceptible to lightning strikes. Therefore, lightning protection equipment is crucial. It can effectively guide lightning current into the ground and protect the wind turbine for safe and stable operation.

This can easily cause irreversible damage to key components of wind turbines, such as blades and generators, increasing the frequency of equipment failures and maintenance costs. Therefore, those skilled in the art have provided a lightning protection device for wind power generation to solve the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 An embodiment of this utility model is provided: a lightning protection device for wind power generation, including a device body 1 and multiple lightning rods 2. A soil moisture sensor 3 is fixedly installed on one side of the upper part of the bottom of the device body 1, a temperature sensor 4 is fixedly installed on the other side of the upper part of the bottom of the device body 1, ultrasonic transducers 5 are fixedly installed on both sides of the lower part of the bottom of the device body 1, and a grounding mechanism 6 is fixedly installed in the middle position of the bottom of the device body 1.

[0026] Specifically, the main body 1 connects and fixes the various components of the equipment to ensure its stability during use. The lightning rod 2 can be used to intercept lightning strikes and conduct the lightning current into the ground to protect the wind power generation equipment. The soil moisture sensor 3 can monitor the soil moisture around the equipment in real time so as to adjust the operating status of the equipment or take corresponding measures according to the moisture conditions. The temperature sensor 4 is mainly used to monitor the internal temperature at the bottom of the main body 1, thereby providing early warning of potential failure risks. The ultrasonic transducer 5 uses the characteristics of ultrasonic waves to loosen the soil around the equipment, improve the soil's permeability and conductivity, and thus optimize the grounding performance of the lightning protection equipment. The grounding mechanism 6 can quickly conduct the lightning current into the ground to ensure the safety of the wind power generation equipment and personnel.

[0027] Reference Figure 1 , Figure 5The main body of the equipment 1 includes a buried box 101. A support rod 103 is fixedly installed on the upper end of the buried box 101. A drive shaft 105 is fixedly installed on the upper end of the support rod 103. Multiple blades 104 are fixedly installed at the output end of the drive shaft 105. A lead wire 102 is fixedly installed at the lower end of the drive shaft 105. Multiple lightning rods 2 are fixedly installed on one side of the blades 104. Each lightning rod 2 includes a fixing block 203. A first threaded rod 202 is threaded on the lower end of the fixing block 203. A connecting block 201 is fixedly installed at the lower end of the first threaded rod 202. A second threaded rod 204 is threaded on the upper end of the fixing block 203. A needle body 205 is fixedly installed at the upper end of the second threaded rod 204.

[0028] Specifically, in the main body 1, the buried box 101 is used to bury part of the main body 1 underground, which plays a role in stabilizing the entire equipment and protecting some internal electronic components from the direct influence of the external environment. The support rod 103 can be used to support the drive shaft 105, the blade 104 and other components to operate stably in the wind. The blade 104 will rotate around the drive shaft 105 under the action of wind. In the structure of the lightning rod 2, the connecting block 201 is connected to the fixing block 203 through the first threaded rod 202. This threaded connection method is convenient for installation and disassembly. When it is necessary to replace or repair the lightning rod 2, it can be easily removed from the blade 104. The needle body 205 is connected to the fixing block 203 through the second threaded rod 204. By adjusting the thread depth of the second threaded rod 204 in the fixing block 203, the extension length of the needle body 205 can be adjusted to adapt to different lightning protection requirements.

[0029] Reference Figures 1-4 The grounding mechanism 6 includes a grounding box 601, two first grounding rings 602, and multiple second grounding rings 606. Multiple second connecting rods 605 are fixedly installed at the lower ends of the two first grounding rings 602. The upper end of the grounding box 601 is fixedly connected to the lead wire 102. First connecting rods 604 are fixedly installed on both sides of the lower end of the grounding box 601. The side of the two first connecting rods 604 away from the grounding box 601 is fixedly connected to the first grounding ring 602. The upper ends of the multiple second grounding rings 606 are fixedly connected to the second connecting rods 605. Grounding rods 603 are fixedly installed at the lower ends of the multiple second grounding rings 606.

[0030] Specifically, in the grounding mechanism 6, the grounding box 601 is a key component connecting the entire grounding mechanism 6 to the main body 1 of the equipment. It is connected to the drive shaft 105 through the lead wire 102, which can smoothly introduce lightning current into the grounding mechanism 6. The first grounding ring 602 and the second grounding ring 606 cooperate with each other to form a large-area grounding network. The first grounding ring 602 is connected to the grounding box 601 through the first connecting rod 604, and multiple second connecting rods 605 are set at its lower end to connect multiple second grounding rings 606. The second grounding rings 606 further expand the grounding coverage. Multiple grounding rods 603 are connected to the second grounding rings 606 and extend into the ground, which can ensure a good electrical connection with the earth and quickly and effectively introduce lightning current into the earth, thereby realizing lightning protection for wind power generation equipment.

[0031] Working principle: When lightning occurs, the lightning rod 2, which is in a higher position and constantly changes position under the drive of the blade 104, is the first to be struck by the lightning. The strong current generated by the lightning is conducted through the lightning rod 2 to the blade 104, and then through the drive shaft 105 and the lead wire 102 into the grounding box 601. The grounding box 601 distributes the current to two first grounding rings 602. The first grounding rings 602 transmit the current to multiple second grounding rings 606 through the second connecting rod 605. Finally, multiple grounding rods 603 introduce the current into the ground. During this process, the soil moisture sensor 3 and the temperature sensor 4 monitor the soil moisture and the internal temperature of the equipment in real time. Once an abnormality is detected, the information will be fed back in time. At the same time, the ultrasonic transducer 5 will work according to the set time interval to loosen the surrounding soil and ensure good conductivity of the grounding. This ensures that the entire lightning protection equipment can operate stably and efficiently, effectively protecting the wind power generation equipment from lightning damage.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
