A first sealing block 6 and a second sealing block 7 are fixedly connected in the rotating cylinder 2, a one-way air inlet channel 61 allowing air to enter the rotating cylinder 2 from the outside is arranged on the first sealing block 6, a one-way exhaust channel 71 allowing air to be exhausted from the rotating cylinder 2 to the outside is arranged on the second sealing block 7, the one-way air inlet channel 61 and the one-way exhaust channel 71 are respectively positioned at the inner side and the outer side of the transparent plate 5, so that air flow is exhausted from the outside along the arrow direction in fig. 2, it is required to be noted that the one-way air inlet channel 61 is provided with two output ports, and the two output ports are respectively communicated with the two arc-shaped cavities 8; the one-way exhaust channel 71 is provided with two input ports, and the two input ports are respectively communicated with the two arc-shaped cavities 8.
The first sealing block 6, the second sealing block 7 and the rotating cylinder 2 jointly form two closed arc-shaped cavities 8, the arc-shaped cavities 8 are connected with piston blocks 9 in a sliding and sealing mode, one-way air inlet valves are arranged on the piston blocks 9 and allow air to be conveyed to the direction of the second sealing block 7 from the first sealing block 6 in a one-way mode, and therefore air flow in the rotating cylinder 2 flows along the direction shown by an arrow in fig. 3.
The working principle of the embodiment is as follows:
in the initial state, the two piston blocks 9 (hereinafter referred to as piston block a and piston block B, respectively for convenience of description) are located at the lowermost side of the rotary cylinder 2 under the action of their own gravity, and are separated by a first seal block 6 (hereinafter referred to as seal block a) and a second seal block 7 (hereinafter referred to as seal block B) (as shown in the leftmost drawing of fig. 4); along with the rotation of the rotating cylinder 2, the sealing block a pushes the piston block A to move upwards, meanwhile, the piston block B is always positioned at the lowest side of the rotating cylinder 2 under the action of the piston block B, so that relative displacement occurs between the piston block B and the rotating cylinder 2, and in the process that the piston block B gradually moves from the sealing block a to the sealing block B, airflow enters the sealing block B from the sealing block a and the input ports of the arc-shaped cavities 8 and is then discharged.
As the rotary cylinder 2 continues to rotate, the piston block a gradually rises to the uppermost end of the rotary cylinder 2, and at the same time, the sealing block B gradually approaches the piston block B (as shown in the middle of fig. 4);
when the piston block A rotates to the left side of the vertical axis of the rotating cylinder 2, the piston block A rapidly slides to the lowest side of the rotating cylinder 2 under the action of gravitational potential energy, so that relative displacement occurs between the piston block A and the rotating cylinder 2, and in the process that the piston block A moves from the sealing block a to the sealing block b, airflow enters the sealing block b from the sealing block a and the input ports of the arc-shaped cavity 8 and is then discharged. (as shown in the right-most drawing in FIG. 4);
the rotating cylinder 2 rotates continuously, so that the piston block a and the piston block B move in a reciprocating manner in the arc-shaped cavity 8, and the air at the input end of the one-way air inlet channel 61 can be continuously conveyed to the output end of the one-way air outlet channel 71 by matching with the one-way air inlet channel 61, the one-way air outlet channel 71 and the one-way air inlet valve, wherein the flowing direction of the air flow is shown by the arrow direction in fig. 3.
The embodiment can continuously extract heat flow generated by the monitor body 1 under the action of external wind force, thereby realizing active convection heat dissipation and greatly improving the heat dissipation efficiency; it is worth mentioning that when the lens cap 4 continuously rotates along with the rotary cylinder 2, a small amount of dust attached to the surface of the lens cap 4 continuously appears in each frame of picture, and according to the phenomenon of visual persistence, the dust disappears in the lens, thereby improving the shooting effect.
