In the following description, the outer diameter of the first transmission wheel 14 is increased, and the second transmission wheel 16, the second rotating shaft 17 and the rectangular sliding block 19 are self-adaptively closed to the sleeve 1 after overcoming the elastic force of the return spring 20 in the n-shaped frame 18, and are away from each other otherwise;
in use, reference is made to fig. 3 and 4.
The sliding sleeve 21 drives the rectangular sleeve 22 to axially move on the first rotating shaft 3, and the output mode of the axial movement is described in detail in the following;
air is fed into the air guide cavity 24 from bottom to top through the air inlet pipe 23, and the specific feeding manner is described in detail below;
the second rotating disc 25 rotates on the air inlet pipe 23 intermittently, so that the exhaust through holes 27 can be intermittently matched with the air leakage holes 26 uniformly formed in the air inlet pipe 23, and when the exhaust through holes 27 coincide with the air leakage holes 26, air collected in the air inlet pipe 23 can be released, and the high-pressure state is relieved;
refer to fig. 7, 3 and 2.
The sliding sleeve 21 drives the rectangular sleeve 22 and the first inclined plane block 28 and the second inclined plane block 29 on the rectangular sleeve 22 to axially reciprocate relative to the first rotating shaft 3;
in fig. 7, when the first inclined block 28 and the second inclined block 29 move to the right synchronously with the rectangular sleeve 22, the inclined surface on the first inclined block 28 pushes the shifting block 30 which is currently located at the tangential position on the left side of the second rotating disc 25, so that the second rotating disc 25 deflects on the air inlet pipe 23 in the counterclockwise direction, and then the first inclined block 28 and the second inclined block 29 move to the left synchronously with the rectangular sleeve 22, so that the inclined surface on the second inclined block 29 contacts with the shifting block 30 and generates extrusion, and the shifting block 30 drives the second rotating disc 25 to continue to rotate on the air inlet pipe 23; the next paddle 30 is also rotated into a pre-engagement position with the first ramp block 28 by the rotation described above.
Referring to fig. 5, it is mentioned that the air inlet pipe 23 is filled with air from top to bottom, and the air is partially transferred to the air guide chamber 24, so that the pressure inside the air guide chamber 24 increases, the piston plate 32 in the high-pressure environment moves in the supporting pipe 31 in a direction away from the air guide chamber 24, and the extension rod 33 extends out of the driving wheel 14, the extension rod 33 and the supporting plate 34 in the extending state support the driving belt 15, so that the outer diameter of the driving wheel 14 increases, and under the condition that the linear speed of the driving belt 15 is unchanged, the outer diameter of the driving wheel 14 increases, the rotating speed of the driving wheel 14 and the rotating shaft 3 decreases, and vice versa, the rotating speed of the driving wheel 14 and the rotating shaft 3 increases.
Refer to fig. 6, 3 and 2.
The transmission arm 39 moves synchronously through the axial movement of the rectangular sleeve 22 relative to the first rotating shaft 3, and the piston plate two 38 is driven by the transmission arm 39 to reciprocate in the piston cylinder 37, so that the space at the position M in fig. 6 is increased or decreased;
m is composed of a piston cylinder 37 and an air inlet pipe 23 and is composed of a piston plate II 38, a check valve I35 and a check valve II 36 after being sealed.
When the volume in the M space decreases and the pressure increases, the air in the M space is transferred downward into the air guide chamber 24 through the one-way valve two 36, and the outside air is introduced into the M space through the one-way valve one 35.
The gas in the gas guide cavity 24 is supplemented in such a reciprocating way;
it is also mentioned that, when the exhaust through holes 27 and the air leakage holes 26 are intermittently overlapped, the high-pressure air in the air guide chamber 24 is exhausted, and the increase and decrease of the air pressure in the air guide chamber 24 are realized by the cooperation between the two.
Refer to fig. 1 and 2.
When the water absorbed on the first water absorption folded paper 9 and the second water absorption folded paper 10 is increased and moves centrifugally in the movable through groove 6 relative to the first rotating shaft 3, the movable block 7 moves in the movable through groove 6 towards the direction away from the first rotating shaft 3, under the rotating fit of the rotating arm 41, the sliding sleeve 21 can drive the rectangular sleeve 22 to move towards the first rotating disc 5 on the first rotating shaft 3, at the moment, the air pressure in the corresponding air guide cavity 24 is reduced, the rotating speed of the first rotating shaft 3 is increased, the first water absorption folded paper 9 can be further extruded in the inner wall of the movable through groove 6 through the movable block 7, so that liquid water is smoothly extruded and discharged, finally seeps out through the liquid outlet 11, and is finally collected in the collecting shell 13 through conduction of the liquid guide tube 12.
After the liquid is extruded, inertia is reduced, and under the elastic force fit of the tension spring 8, the movable block 7 can rapidly drive the first water absorption folded paper 9 to reset, in the resetting process, under the rotating fit of the rotating arm 41, the sliding sleeve 21 can drive the rectangular sleeve 22 to move towards the direction far away from the first rotating disc 5, the air pressure in the corresponding air guide cavity 24 is increased, the rotating speeds of the first driving wheel 14 and the first rotating shaft 3 are reduced, the resetting of the movable block 7 with the first water absorption folded paper 9 is further promoted, in the resetting process, the movable block 7 can extrude the second water absorption folded paper 10, water collected on the second water absorption folded paper 10 is extruded, then the water is thrown out through the first rotating disc 5, and finally the water is exuded through the liquid outlet hole 11.
Through the cooperation use between the above-mentioned structure, solved in the in-service use, because urban rail transit station is located the underground mostly, the air is comparatively moist, and current equipment wets easily, influences the life of equipment, and is difficult to separate the moisture in the air among the traditional low voltage distribution system management and control equipment and gets rid of, has the problem of potential safety hazard.
