The energy structure dominated by fossil fuels is not only difficult to sustain in terms of resources, but also brings serious problems to the environment. Wind power is generated through wind power, and wind energy is a renewable energy source that can reduce pollution to the environment.

[0003] When generating electricity through wind power, a wind wheel is required, and when the wind wheel is installed, it needs to be locked by a locking disk. The wind wheel locking disk is an important component of the wind power generation system. Its function is to rigidly connect the main shaft and the hollow shaft sleeve of the gear box into one, thereby ensuring the normal operation and maintenance of the wind power generation system. For the convenience of installation, the existing wind wheel locking disk is usually installed in a combined manner. However, in actual application, the combined installation is time-consuming and laborious for operators, and if the connection position is damaged or deformed, it cannot be easily replaced, which is not economical and practical.

The clamping mechanism 4 includes a mounting groove 41 provided on the top surface of the connecting plate 3, and the center of the bottom surface of the inner cavity of the mounting groove 41 and the top surface of the connecting plate 3 are provided with a threaded hole matching the structural size of the connecting bolt 6. The cavity is provided with a clamping spring 42, and the inner diameter of the horizontal section of the clamping spring 42 is larger than the outer diameter of the connecting bolt 6. The top of the clamping spring 42 is fixedly connected to the clamping column 43, and the top of the clamping column 43 is a common smooth arc structure. The clamping spring 42 is fixedly connected to the mounting groove 41 at one end away from the clamping column 43. A clamping column 43 is provided above the clamping spring 42, and a slot hole matching the structural size of the connecting bolt 6 is penetrated on the top surface of the clamping column 43, that is, the connecting bolt 6 penetrates the slot hole on the top of the clamping column 43, passes through the inner cavity of the clamping spring 42, and is inserted into the threaded hole at the bottom of the inner cavity of the mounting groove 41.

[0023] The top surfaces of the first locking disc 1 and the second locking disc 2 are both threadedly connected with a reinforcing bolt 5. The first locking disc 1 is close to the connecting plate 3 and the second locking disc 2 is close to the connecting plate 3. An insertion groove 9 is provided. One end of the reinforcing bolt 5 is located in the inner cavity of the insertion groove 9. The top surface of the connecting plate 3 is provided with a threaded hole that matches the structural size of the reinforcing bolt 5. That is, when the connecting plate 3 is limited in the inner cavity of the insertion groove 9, the reinforcing bolt 5 passes through the inner cavity of the insertion groove 9 and is threadedly connected to the connecting plate 3. The top surface of the first locking disc 1 and the top surface of the second locking disc 2 The surfaces are both threadedly connected with connecting bolts 6, and the first locking disk 1 and the second locking disk 2 are both provided with connecting grooves 7 at one end away from the connecting plate 3, and a clamping groove 10 matching the structural size of the clamping column 43 is provided at the top of the inner cavity of the connecting groove 7. When the clamping column 43 is clamped in the inner cavity of the clamping groove 10, the second locking disk 2 and the first locking disk 1 are temporarily assembled together, and a threaded hole matching the structural size of the connecting bolt 6 is provided at the top of the inner cavity of the connecting groove 7, and a limiting mechanism 8 is provided on one side surface of the first locking disk 1 and one side surface of the second locking disk 2.

[0024] like Figure 2 As shown, the limiting mechanism 8 includes a limiting groove 81 opened on one side surface of the first locking disk 1 and one side surface of the second locking disk 2, and a toggle block 82 is embedded and slidably connected in the inner cavity of the limiting groove 81. The toggle block 82 is provided with a square toggle groove on one side surface away from the limiting groove 81, and the top surface of the toggle block 82 is fixedly connected to the limiting spring 83, and the top of the limiting spring 83 is fixedly connected to the limiting groove 81, and the bottom surface of the toggle block 82 is fixedly connected to the limiting column 84, one end of the limiting column 84 passes through and is movably connected to the limiting groove 81, and the limiting column 84 is in an oblique cone structure away from the end of the toggle block 82. A limiting hole 11 matching the structural size of the limiting column 84 is opened on the top surface of the connecting plate 3. When the limiting column 84 is inserted into the limiting hole 11, the position of the connecting plate 3 is temporarily installed and limited.

[0025] It should be noted that: Figure 1 and Figure 2 As shown, the height and outer diameter of the reinforcing bolt 5 and the connecting bolt 6 are completely consistent, which can ensure that the construction is more convenient, and the top surfaces of the first locking plate 1 and the second locking plate 2 are provided with grooves that match the structural dimensions of the nut parts of the reinforcing bolt 5 and the nut parts of the connecting bolt 6. That is, after the reinforcing bolt 5 and the connecting bolt 6 are installed, the top surface of the reinforcing bolt 5 and the top surface of the connecting bolt 6 are flush with the outer surface of the assembled wind wheel locking plate and will not protrude.

[0026] Working principle: When in use, bring the first locking disk 1 and the second locking disk 2 closer together, align the connecting plate 3 with the opposite connecting groove 7, and then press the clamping column 43 by hand or directly press the connecting plate 3 into the connecting groove 7. At this time, the clamping column 43 is temporarily retracted into the installation groove 41, and the clamping spring 42 is deformed. Then, the connecting plate 3 is inserted into the connecting groove 7. At this time, under the action of the clamping spring 42, the clamping column 43 is pressed against the top of the inner cavity of the connecting groove 7 until the connecting plate 3 completely enters the connecting groove 7. At this time, the clamping column 43 is aligned with the clamping groove 10, and the clamping spring 42 returns to its original state, driving the movement of the clamping column 43, and inserting it into the clamping groove 10, temporarily connecting the first locking disk 1 and the second locking disk 2 by the connecting bolt 6. The threaded connection is connected to the connecting plate 3, thereby combining the first locking plate 1 and the second locking plate 2 for installation. Furthermore, before the first locking plate 1 and the second locking plate 2 are combined and installed, if the connecting plate 3 assembly is damaged or deformed, the reinforcing bolt 5 can be rotated and removed, and then the toggle block 82 can be raised to drive the limit column 84 to leave the limit hole 11 at the top of the deformed connecting plate 3. At this time, the connecting plate 3 is removed. Similarly, the new connecting plate 3 is inserted into the insertion groove 9. The toggle block 82 drives the movement of the limit column 84, and the connecting plate 3 is inserted into the insertion groove 9. The limit column 84 temporarily limits the connecting plate 3, and the position of the connecting plate 3 is completely limited by the reinforcing bolt 5 to complete the replacement of the connecting plate 3.
