Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine generators, and in particular to a wind turbine generator protection component for a transformer substation and a use method thereof. Background Art

[0002] A wind turbine is a device that uses wind energy to convert it into electrical energy. It usually consists of blades, a main shaft, a generator and a tower. The blade is a key component installed on the main shaft. It drives the main shaft to rotate by capturing and utilizing the kinetic energy of the wind. The blade is generally designed with three or more blades, which enables it to capture wind energy more effectively. The shape and design of the blade also affect efficiency and stability. The main shaft is the part that converts wind energy into mechanical energy. It connects the blades and the generator. When the wind blows through the blades, the wind pressure causes the main shaft to rotate, thereby generating mechanical energy. The generator is the key part that converts mechanical energy into electrical energy. Generally speaking, wind turbines use synchronous generators or asynchronous generators. When the main shaft rotates, the coils and magnetic fields inside the generator interact to generate current, thereby generating electrical energy. The tower is the structure that supports the entire wind turbine. Its height supports the position of the blades to better capture wind energy. The height of the tower usually varies according to geographical conditions and wind energy resources. Existing wind turbine security access control systems mainly rely on manual inspection or basic electronic control, and usually lack effective response measures for severe weather conditions, such as direct impact and additional mechanical loads caused by high wind speeds. Since most wind turbines are located in open areas, such as mountain tops, plains and coastlines, they are often exposed to severe wind forces. In addition, maintenance work in such an environment also increases the risk of personnel safety. Summary of the invention

[0010] A method for using a wind power generation protection component of a substation comprises the following steps: Step 1: The staff uses the access control module to interact, and the access control module collects the staff's facial information and transmits the collected data to the network control module; Step 2: After the network control module matches and verifies the identity information of the staff member according to the built-in program, the network control module controls the electromagnetic door lock to release the locking state of the sealed door inside the door frame; Step 3: The first electric telescopic rod is shortened to drive the first connecting seat, and the first connecting seat drives the sealing door, so that the sealing door rotates forward with the axis of the rotating frame as the axis and opens with the cooperation of the rotating frame, and the staff passes through the door frame to enter the interior of the wind turbine; Step 4: After the sensor detects that a worker passes below, the first electric telescopic rod extends to drive the first connecting seat, so that the first connecting seat drives the sealing door to rotate backward to close the door frame; Step 5: If the worker does not appear in the sensing area below the sensor again for a long time, it is determined that the worker is in danger inside the wind turbine, and the sensor sends a distress signal to the external terminal through the network control module; Step 6: After the staff member appears below the sensor again, the sensor sends a signal to the network control module, and the prefabricated program inside the network control module controls the first electric telescopic rod to start, so that the sealed door is opened again, and after the staff member walks out, the first electric telescopic rod drives the sealed door to close in cooperation with the first connecting seat; Step 7: The wind detection module senses the wind speed and wind direction outside the wind turbine and sends the data to the network control module; Step 8: When the positive wind blowing toward the inside of the door frame is strong, the second electric telescopic rod extends to drive the rotating rod, and the rotating rod drives the second mounting seat to rotate inwardly with the rotating connection with the fixed seat pin shaft as the axis, and the second mounting seat drives the mounting frame to move inwardly under the limiting action of the limiting rod, and drives the third wind shield to move inwardly under the cooperation of the mounting frame and the rotating frame, so that the third wind shields on the left and right sides move inwardly to the front side of the first wind shield and the second wind shield, so as to block the positive wind; Step nine: The third electric telescopic rod drives the rotating frame to rotate inward or outward through the third connecting seat. The rotating frame changes the angle direction of the third wind shield, cooperates with the first wind shield and the second wind shield to allow the staff to pass through. At the same time, the wind direction is guided to blow to both sides to reduce the wind force of the positive wind, so as to facilitate the staff to walk out.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The facial information of the staff is collected through the access control module. The network control module matches and verifies the identity information of the staff according to the built-in program. The electromagnetic door lock releases the locking state of the sealed door. The first connecting seat drives the sealed door to rotate forward and open. After the sensor detects that the staff below has passed, if the staff does not appear in the sensing area below the sensor for a long time, it is judged that the staff is in danger inside the wind turbine. The sensor sends a distress signal to the external terminal through the network control module.

[0012] 2. The wind detection module senses the external wind speed and wind direction of the wind turbine. The second electric telescopic rod drives the rotating rod to drive the third wind shield to move inward with the cooperation of the second mounting seat, the mounting frame and the rotating frame, so that the third wind shields on the left and right sides move inward to the front position of the first wind shield and the second wind shield, so as to block the positive wind blowing toward the inside of the door frame. The third electric telescopic rod drives the third connecting seat to move inward or outward, and drives the rotating frame to rotate axially inward or outward at the rotating connection with the mounting frame pin shaft with the third connecting seat, so that the rotating frame changes the angle direction of the third wind shield, cooperates with the staff to guide the wind direction to blow to both sides at the same time, and reduces the wind force of the positive wind.

[0013] To sum up, the present invention adopts a more powerful opening mechanism to overcome the resistance of high wind speed to the safety door, ensuring that the safety door can be opened stably, and a windproof mechanism is provided to reduce the impact of external wind speed on the safety door without affecting the normal use of the safety door, reduce wind speed and wind pressure, and enable staff to enter and exit normally.

8. The method for using a wind power generation protection component of a substation according to claim 7, characterized in that: The following steps are involved: Step 1: The staff member interacts with the access control module (35), and the access control module (35) collects facial information of the staff member and transmits the collected data to the network control module (21); Step 2: After the network control module (21) matches and verifies the identity information of the staff member according to the built-in program, the network control module (21) controls the electromagnetic door lock (36) to release the locking state of the sealed door (34) inside the door frame (31); Step 3: The first electric telescopic rod (38) is shortened to drive the first connecting seat (310), and the first connecting seat (310) drives the sealing door (34), so that the sealing door (34) is rotated and opened toward the front side with the axis of the rotating frame (33) as the axis under the cooperation of the rotating frame (33), and the staff passes through the door frame (31) to enter the interior of the wind turbine (1); Step 4: After the sensor (32) detects that a worker has passed below, the first electric telescopic rod (38) extends to drive the first connecting seat (310), so that the first connecting seat (310) drives the sealing door (34) to rotate backward to close the door frame (31); Step 5: If the worker does not appear in the sensing area below the sensor (32) again for a long time, it is determined that the worker is in danger inside the wind turbine (1), and the sensor (32) sends a distress signal to the external terminal through the network control module (21); Step 6: After the staff member appears below the sensor (32) again, the sensor (32) sends a signal to the network control module (21), and a pre-programmed program inside the network control module (21) controls the first electric telescopic rod (38) to start, so that the sealed door (34) is opened again, and after the staff member walks out, the first electric telescopic rod (38) drives the sealed door (34) to close in cooperation with the first connecting seat (310); Step 7: The wind detection module (22) senses the wind speed and wind direction outside the wind turbine (1) and sends the data to the network control module (21); Step 8: When the positive wind blowing toward the inside of the door frame (31) is strong, the second electric telescopic rod (48) extends to drive the rotating rod (47), and the rotating rod (47) drives the second mounting seat (410) to rotate inwardly with the rotation connection point with the pin shaft of the fixing seat (45) as the axis, and the second mounting seat (410) drives the mounting frame (411) to move inwardly under the limiting action of the limiting rod (46), and drives the third wind shield (415) to move inwardly under the cooperation of the mounting frame (411) and the rotating frame (412), so that the third wind shield (415) on the left and right sides moves inwardly to the front side position of the first wind shield (41) and the second wind shield (42), so as to block the positive wind; Step nine: The third electric telescopic rod (413) drives the rotating frame (412) to rotate inward or outward through the third connecting seat (414), and the rotating frame (412) changes the angle direction of the third wind shield (415), so as to guide the wind direction to blow to both sides when the staff pass through the first wind shield (41) and the second wind shield (42), thereby reducing the wind force of the positive wind and making it easier for the staff to walk out.
