The temporary storage cavity 66 is connected to the bottom wall of the temporary storage box 65 through a liquid leakage channel 67. The top wall of the support plate 3 is detachably connected to a waste oil recovery box 71. ;

[0023] Embodiment 1: The support plate 3 is installed on the top wall of the cooling tower 1, the lower end of the reducer output shaft 6 is connected to the fan blade, the driving motor 7 is turned on to make the motor output shaft 8 drive the first connecting piece 55, the transmission bar 60, the second connecting piece 57, the reducer input shaft 5 and the fan blade to rotate, and the fan blade rotates to discharge the waste heat of the cooling tower 1. Under the action of the negative pressure in the cooling tower 1, the fan will rotate in the opposite direction. The reversal of the fan will bring certain hidden dangers to the personnel who repair the cooling tower 1. The setting of the one-way bearing 9 can prevent the reversal of the fan. When it is necessary to replace the lubricating oil of the reducer body 2, the cooling tower 1 and the driving motor 7 are stopped, and the user pulls the handle 72 under the cooling tower 1 to make the traction line 20 pull the first slide 19 to the right. The first slide 19 and the two second slides 22 are against each other, the first slide 19 drives the two second slides 22 to move right, the second slide 22 drives the magnet sheet 23, the connecting strip 25, the push strip 26, and the push wheel 27 to move right, the push wheel 27 drives the first wedge block 30 to rotate, the first wedge block 30 rotates around the rotating shaft 31, so that one of the blocking blocks 33 is separated from the oil inlet pipe 13, and the other blocking block 33 is separated from the oil outlet pipe 15, the old lubricating oil in the reducer body 2 flows out from the oil outlet pipe 15, and the old lubricating oil flows to the temporary storage chamber 66 of the temporary storage box 65. Since the caliber of the leakage channel 67 is very small, the speed at which the old lubricating oil passes through the leakage channel 67 is very slow, and it passes through the leakage channel 67 drop by drop, and the temporary storage chamber 66 The old lubricating oil in the temporary storage box 65 gradually increases, and the mass of the temporary storage box 65 increases. When the mass of the temporary storage box 65 is greater than a certain value, the gravity movable plate 64 rotates, thereby causing the gravity movable plate 64 to rotate counterclockwise, and the gravity balance member 68 moves upward. The magnetic attraction of the gravity balance member 68 causes the lower magnet sheet 23 to overcome the elastic force of the second elastic member 24 and move downward, thereby causing the second slide 22 to move downward along the connecting strip 25, and the lower second slide 22 is separated from the first slide 19. The connecting strip 25 moves leftward along the third slide rail 70 under the elastic force of the third elastic member 28 and is reset. The transfer bar 32 is reset to a horizontal state under the elastic force of the fourth elastic member 34, and the blocking block 33 and the oil outlet pipe 15 are re-aggressed to block the oil outlet pipe 15. The gravity balance member 68 pushes the slide bar 35 and the second wedge block 36 to overcome the elastic force of the fifth elastic member 37 and move upward, so that the second wedge block 36 pushes the third wedge block 45 and the oil stop plate 43 to overcome the elastic force of the sixth elastic member 431 and move left, so that the plate hole 44 and the refueling channel 41 are connected, and the new lubricating oil in the oil storage chamber 39 flows out from the refueling channel 41 to the first guide bucket 14, and is drained to the oil inlet pipe 13 through the first guide bucket 14 and enters the reducer body 2. The liquid level in the oil storage chamber 39 will gradually decrease, and the floating liquid level indicator 47 will move downward as the liquid level decreases. The floating liquid level indicator 47 is aligned with the scale on the glass window 46. The user can observe the scale pointed to by the floating liquid level indicator 47 under the cooling tower 1 to judge how much lubricating oil is added.

[0024] When it is necessary to stop adding lubricating oil, the user releases the handle 72, and the first slide 19 is reset to the left along the second slide rail 69 under the elastic force of the first elastic member 18, and the upper movable blocking mechanism is reset under the elastic force of the third elastic member 28 and the fourth elastic member 34, and the upper blocking block 33 blocks the oil inlet pipe 13 again to prevent impurities from entering the reducer body 2 from the oil inlet pipe 13 and affecting the lubrication effect. When the old lubricating oil in the temporary storage chamber 66 gradually flows into the waste oil recovery tank 71 from the leakage channel 67, the mass of the temporary storage box 65 gradually decreases. When the mass of the temporary storage box 65 is less than a certain value, the gravity activity Under the action of gravity of the movable plate 64, the gravity movable plate 64 reverses and resets, the gravity balance member 68 moves downward, and the magnet piece 23 loses its magnetic attraction and moves upward and reset under the elastic force of the second elastic member 24. The second slide 22 moves upward and resets to the right of the first slide 19. After the slide bar 35 loses the supporting force of the gravity balance member 68, the second wedge block 36 and the slide bar 35 move downward and reset under the elastic force of the fifth elastic member 37. After the third wedge block 45 loses the thrust of the second wedge block 36, the oil stop plate 43 moves right and resets under the elastic force of the sixth elastic member 431, and the refueling channel 41 is blocked again to stop refueling.

[0025] In this embodiment, the lubricating oil in the reducer body 2 can be replaced by pulling the traction line 20 under the cooling tower 1, and the oil inlet pipe 13 and the oil outlet pipe 15 are automatically connected and blocked at an appropriate time, so as to skillfully realize the oil filling and draining operations. The user does not need to climb up the higher cooling tower 1 and manually unscrew the cover and perform a series of tedious operations to replace the lubricating oil.

[0034] When the fan is installed and repaired, the drive motor 7 will be rotated forward and reverse to debug the drive motor 7. However, due to the existence of the one-way bearing 9, the drive motor 7 cannot rotate forward and reverse. Therefore, when the magnet block 54 moves to the right, the magnetic attraction of the magnet block 54 causes the magnet ring 59 to overcome the elastic force of the seventh elastic member 61 and move downward, so that all the transmission bars 60 are separated from the connection groove 56, and the first connecting piece 55 and the magnet ring 59 are disconnected. The user can replace the lubricating oil while debugging the drive motor 7 forward and reverse. One person pulls the handle 72, and the other person performs it on the cooling tower 1. The drive motor 7 is debugged to improve the detection efficiency. After the debugging is completed, the drive motor 7 is turned off. After the lubricating oil is replaced, the handle 72 is released, and the transmission rod 48 drives the cleaning strip 49, the extension strip 53, and the magnet block 54 to move left and reset. The magnet ring 59 moves up and reset under the elastic force of the seventh elastic member 61. The transmission bar 60 and the bottom wall of the first connecting piece 55 are abutted. When the motor output shaft 8 rotates again, the connecting groove 56 is aligned with the transmission bar 60, and the transmission bar 60 will be inserted into the connecting groove 56 under the elastic force of the seventh elastic member 61, thereby completing the connection between the first connecting piece 55 and the magnet ring 59.

[0035] This embodiment can automatically wipe and clean the fan dust screen 52 while replacing the lubricating oil to prevent the fan dust screen 52 from being blocked by dust and affecting the heat dissipation effect, and can automatically temporarily disconnect the connection between the motor output shaft 8 and the reducer input shaft 5 to facilitate the removal of the rotation direction restriction of the one-way bearing 9 on the motor output shaft 8, so that the motor output shaft 8 can be debugged in forward and reverse rotation.

[0036] According to an optional implementation of the present invention, the first elastic member 18 , the second elastic member 24 , the third elastic member 28 , the fourth elastic member 34 , the fifth elastic member 37 , the sixth elastic member 431 and the seventh elastic member 61 are all iron springs.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
