However, with the increase in the capacity of the generator in the wind turbine, the corresponding gearbox transmission ratio is also continuously increasing (large-capacity double-fed asynchronous units).

The push plate 204b is a figure "8" structure, so that the areas of the upper and lower sides and the left and right sides are different and the areas of the symmetrical positions are the same. When the fastest position of the push plate 204b contacts the follower block 203d, it will push the push block 202a to move with the push column 203c on the push groove 203b. The locking column 204c is set on the push plate 204b. The locking column 204c is movably connected to the push plate 204b. The locking column 204c is in the shape of two cylinders. The side of the push plate 204b is curved to facilitate contact and pushing. The locking column 204c is fixedly connected to the two sides of the push block 202a and can be moved and embedded in the double-sided groove 201c to fix the position of the push block 202a. When the widest area of ​​the push plate 204b moves to contact the locking column 204c, the locking column 204c will move into the double-sided groove 201c to further fix the position of the push block 202a on the placement groove 201a.

[0056] Furthermore, the mounting member 205 includes a mounting plate 205a, a first block to be locked 205b, a second block to be locked 205c, a smoke generator 205d and a pressure detector 205e. The mounting plate 205a is arranged on the pushing block 202a, and the mounting plate 205a is embedded in the pushing block 202a. The mounting plate 205a is a double-sided structure and is adapted to the groove shape opened on the upper side of the pushing plate and is sealed and embedded therein.

When the largest area of ​​the pushing plate 204b contacts the locking column 204c, the first locking block 204d on the locking column 204c will enter the second block to be locked 205c for further fixation after installation on the other side of the mounting plate 205a. In this way, the installation stability of the entire mounting plate 205a is further improved, and the smoke generator 205d and the pressure detector 205e are fixedly connected to the upper side of the mounting plate 205a.

[0057] The remaining structures are the same as those of Example 1.

[0058] Operation process: First, the mounting plate 205a with the smoke generator 205d and the pressure detector 205e installed is embedded and sealed on the push plate, wherein the side of the mounting plate 205a can also be installed with the oil temperature detector 101e and the pressure pump 101f for synchronous movement, and then the push block 202a is pushed and installed on the placement groove 201a, so that the shielding plate 201e originally used to shield the placement groove 201a is pushed into the storage groove 201b, and the resistance block 202c is squeezed and contacted along the displacement groove 202 b moves, which will drive the resistance block 202c and the displacement block 202d to move, and the slider 202f will slide down into the entry slot 103b of the moving block 103a with the smoke sensor 202g in the sliding slot 202e located on the block with acceleration. Due to the weight of the slider 202f and the smoke sensor 202g, the limiting ball 103c in the entry slot 103b can limit the position of the slider 202f, so that the smoke sensor 202g can move on the box 101a with the synchronization component 100 for detection;

[0059] At the same time, rotating the rotating handle 204a by 90 degrees can change the widest and narrowest surfaces of the original pushing disk 204b, so that the locking column 204c can enter the double-sided groove 201c to further fix the pushing block 202a, and also drive the first locking block 204d to enter the second waiting locking block 205c to further stabilize one side of the mounting plate 205a, and at the same time, the thrust of the pushing column 203c is reduced and moved to a position close to the rotating handle 204a, so that the follower block 203d can enter the second waiting locking block 205c to further stabilize the other side of the mounting plate 205a;

[0060] When the rotating handle 204a is rotated 90 degrees further or rotated 90 degrees in the opposite direction, the mounting plate 205a will be further stabilized, making it easier to disassemble and replace the detection device.

[0061] Example 3

[0062] A third embodiment of the present invention provides a leakage detection method, comprising the following steps:

[0063] S1. Complete the installation and operation of the detection equipment and compensation equipment through the gearbox self-test device;

[0064] The detection device and the compensation device are controlled by Raspberry Pi, wherein the detection device is composed of a pressure detector 205e, an oil temperature detector 101e and a smoke sensor 202g, and the compensation device is composed of a pressure pump 101f and a smoke generator 205d.

[0065] S2. When the detection pressure of the detection equipment is abnormal, the compensation equipment is started to perform secondary detection;

[0066] Among them, the pressure detector 205e detects low pressure and is activated, and then starts the pressure pump 101f to replenish the pressure to a constant value. At this time, the smoke generator 205d begins to emit smoke above the oil surface, and then the pressure detector 205e detects that the pressure has lost to the set value and then alarms.

[0067] S3. When the compensation device is working, the detection device alarm can determine the leakage location.

[0068] Among them, when the pressure detector 205e is activated but the smoke sensor 202g is not activated, the system prompts that there is a leak above the gear box. When the pressure detector 205e is activated but the smoke sensor 202g is not activated, the system prompts that there is a leak below the gear box.

[0069] Among them, it is necessary to measure and calculate the internal air pressure of the gearbox when it is running, on standby, the oil pump motor is at high speed or low speed, and the mechanical pump is running under the same conditions according to the volume of the gearbox oil at different temperatures, as a protection set value, and the floating value is set at an upper and lower deviation of 3%. When the pressure value is lower than the set value, the pressure pump 101f replenishes the pressure to the set value, and detects it once every 1 minute. After the main control system repeats the detection for 5 times, the 5 pressure values ​​are all lower than the set value, and the pressure pump 101f stops pressurizing. After one minute, the sixth detection pressure value is lower than the fifth, then the main control system determines that there is a leak in the gearbox;

[0070] This detection method detects leakage in the upper and lower parts of the wheel box through key components such as the pressure detector 205e and the smoke sensor 202g, and compensates and alarms through devices such as the pressure pump 101f and the smoke generator 205d. Its judgment logic is based on the pressure loss detected by the pressure detector 205e, and combined with the smoke sensor 202g to judge the leakage point. The working efficiency and accuracy of the detection system are of great significance to ensuring the normal operation of the equipment.
