Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, a kind of embodiment provided by the invention：Turning sleeve is fixed on including turning sleeve 1, by fixing piece
It the fixed block 2 of 1 end face midpoint, the main shaft 3 for being arranged on 2 end face midpoint of fixed block and is fixed at by fastener 31
The flabellum 4 of 3 end of main shaft, the midpoint of the turning sleeve 1 are provided with a mounting groove 5, and the inside of the mounting groove 5 installs one turn
To column 6, the side of the steering column 6 is provided with multiple shrinkage pools 10, and the top of the steering column 6 is provided with the second steering shaft 8, institute
It states the second steering shaft 8 and penetrates the top of the turning sleeve 1 and pass through bearing 7 and be fixedly connected, the top of second steering shaft 8 is consolidated
Surely link block 9 is equipped with, the turning sleeve 1 is internally provided with a ring cavity 16, and the turning sleeve 1 is internally provided with multiple intercommunications
The slot 12 of the inside of ring cavity 16, and the slot 12 is being internally provided with a restraint hole 13 with 16 junction of ring cavity, often
The inside of a slot 12 is mounted on hydraulic section 14, and the end face of the hydraulic section 14 fixes a mandril 15, the mandril
15 penetrate the internal structure of the turning sleeve 1 and end is inserted into the inside of shrinkage pool 10, and the side of the turning sleeve 1 is provided with
One hydraulic tube 17, the added holes 18 for being internally provided with intercommunication outer end and ring cavity 16 of the hydraulic tube 17, the hydraulic tube 17 exist
Positioned at one closing valve 19 of the inside of the added holes 18 installation, the link block 9 is internally provided with spiral hole 11；Multiple slots
Hole 12 is arranged in round shape；Multiple shrinkage pools 10 are arranged in round shape；10 quantity one of multiple slots 12 and multiple shrinkage pools
It causes and reciprocity one by one, before use, it should, should by hydraulic oil pump to the hydraulic oil of the quantitative pressure of inside injection of ring cavity 16
This is note that the hydraulic fluid pressure of injection should be less than the maximum pressure that flabellum main axle structure can drive when being obstructed, so as to make
Flabellum main shaft and motor can be protected by obtaining the device.
Referring to Fig. 3, the hydraulic section 14 includes hydraulic column 141, the first closing chamber 142, the second closing chamber 143 and closing
Pad 144；The side of the hydraulic column 141 is respectively arranged with the first closing chamber 142 and the second closing chamber 143 of upper and lower equity, institute
It states hydraulic column 141 and is being equipped with sealing pad 144 positioned at the inside of 142 and second closing chamber 143 of the first closing chamber；Described
One closing chamber 142 is consistent with the structure size of the second closing chamber 143；Its master of first closing chamber, 142 and second closing chamber 143
Acting on is, playing prevents leaked liquid so that the pressure of liquid can be controlled effectively.
Specifically used mode：In present invention work, link block 9 and the motor output shaft of fan are fixedly connected, when
After motor operation, under the cooperation of mandril 15 and shrinkage pool 10, the rotary state from motor can be transmitted to flabellum main shaft 3
In, it, can not be further when flabellum main shaft 3, which meets external force, to be obstructed so as to drive 4 quick rotation pectinid of flabellum main shaft 3 and flabellum
During rotation, the dynamics of rotation will necessarily be more than the hydraulic pressure of 16 internal hydraulic pressure of ring cavity oil at this time, so at this point, mandril 15 exists
Under the action of external force, shrinkage pool 10 is exited, so at this point, flabellum main shaft 3 can not rotate, and that steering column 6 can be driven to do is useless for motor
Work(rotates, so as to be greatly reduced danger while protecting motor without damage.
