Abstract
A flagpole for preventing a flag from being wound has a tail wing plate parallel to the wind direction, and the wind blowing direction coincides with the direction of the flag to blow the flag. The rotation is always rotated until the tail wing plate is parallel to the wind direction. Because the pterygoid lamina parallels with the wind direction, consequently wind can get into in the inlet air channel I of drainage cover I to get into in the annular chamber I, finally blow off through air outlet I, the air current that blows off from air outlet I is mutually perpendicular with the wind direction, if when taking place horizontal wind suddenly, the flag is when swinging to I direction of air outlet, and it can be blown off to the reversal by the air current that air outlet I blew off, prevents to take place the winding. Wind enters the annular cavity II through the air inlet channel II in the drainage cover II, finally blows out through the air outlet II, and the airflow blown out from the air outlet II is vertical to the wind direction, so that if transverse wind suddenly occurs, when the flag swings towards the direction of the air outlet II, the flag can be blown out by the air flow blown out from the air outlet II in the reverse direction, and the winding is prevented.

When the device is used, a banner 11 is arranged on the rotary drum 4 through a banner clamping mechanism, then the sliding sleeve 13 moves upwards along the flagpole 2 through pulling the pull rope 8, the pull rope 8 is guided in each circular ring 30, winding cannot occur, and the sliding sleeve 13 can only slide up and down along the guide rail 3 and cannot rotate because the guide rail 3 is longitudinally arranged on the flagpole 2. After the flag 11 rises, wind blows the tail wing plate 5, the tail wing plate 5 is stressed to drive the rotary drum 4 to rotate relative to the sliding sleeve 13, until the tail wing plate 5 is parallel to the wind direction, the tail wing plate 5 is not stressed by the wind, the rotary drum 4 is not rotated, at the moment, the wind blowing direction is coincident with the direction of the flag 11, and the flag 11 is blown to fly. The rotation 4 is always rotated until the tail wing plate 5 is parallel to the wind direction. Because the tail wing board 5 is parallel with the wind direction, therefore wind can get into in the inlet air duct I22 of drainage cover I18 to get into annular chamber I25, finally blow out through air outlet I33, the air current that blows out from air outlet I33 is perpendicular with the wind direction mutually, therefore if take place horizontal wind suddenly, when flag 11 swung to air outlet I33 direction, it can be blown out to the opposite direction by the air current that air outlet I33 blew out, prevents to take place the winding. Wind enters the annular cavity II 26 through the wind inlet channel II 24 in the drainage cover II 23 and finally blows out through the wind outlet II 34, and airflow blown out from the wind outlet II 34 is vertical to the wind direction, so that if transverse wind suddenly occurs, the flag 11 swings towards the direction of the wind outlet II 34, and the airflow blown out from the wind outlet II 34 blows in the reverse direction, and the winding is prevented.

Because the tail end of the banner 11 is generally in a sleeve-shaped structure sewn by white cloth, when the banner 11 is fixed, the sleeve at the tail end of the banner 11 is firstly inserted into the vertical rod 37, the cloth is sleeved in the annular area between the vertical rod 37 and the circular hole 51, and the banner 11 is arranged in the open slot 50, so that the installation and the disassembly are very convenient. Because the slot 50 divides two sides of the T-shaped block 9 into two clamping arms, when the two bolts 10 at the upper and lower ends of the banner 11 are screwed, the distance between the two clamping arms is reduced, so that the banner 11 in the slot 50 is clamped and fixed. If the banner 11 needs to be replaced, the bolt 10 is loosened, and the banner 11 is taken out of the slot 50.
If the wind power is too high, the speed of the tail wing plate 5 driven by the wind to rotate the rotary drum 4 is very high, the inertia of the rotary drum 4 is large when the rotary speed is high, so that the rotary drum is not easy to rotate quickly until the tail wing plate 5 is parallel to the wind direction, and the flag 11 is likely to be wound on the rotary drum 4 due to the fast free rotation of the rotary drum 4. Therefore, the device also comprises a plurality of ball grooves 16 which are uniformly arranged on the sliding sleeve 13 at intervals along the circumferential direction, a guide sleeve 27 which is horizontally arranged on the inner wall of the rotary drum 4, a sliding rod 28 which is slidably inserted in the guide sleeve 27, and a spring 29, wherein the spring 29 is positioned in the guide sleeve 27, one end of the spring 29 is connected with the guide sleeve 27, the other end of the spring 29 is connected with the sliding rod 28, the head end of the sliding rod 28 is provided with a ball head, and when the spring 29 is in a free state, the ball head of the sliding rod 28 is. When the rotary drum 4 rotates, the rotary drum extrudes the sliding rod 28 to slide outwards and compresses the spring 29 until the ball head at the head end of the sliding rod 28 is separated from the ball groove 16, then the rotary drum 4 continues to rotate, the spring 29 pushes the sliding rod 28 to slide again until the ball head is inserted into the next ball groove 16, the sliding rod 28 stretches continuously and plays a role of providing slight resistance, when the rotary drum 4 rotates until the tail wing plate 5 is parallel to the wind direction, the sliding rod 28 is inserted into the corresponding ball groove 16 through the ball head, and at the moment, the rotary drum 4 cannot continue to rotate under the inertia effect.
