[0020] Preferably, the pulling frame consists of two pulling rods and a T-shaped rod.

[0021] Preferably, the method for using the pier drainage structure comprises the following steps:

[0022] S1: After filtering rainwater and sewage through the filter net, they are discharged through the drainage pipe. Then, when the cross plate is blown by the wind, the ball rod is driven to swing, so that the second one-way air valve that the upper end of the ball rod abuts against moves downward in the limit sleeve and slides, and the gas is delivered to the air guide pipe through the second one-way air valve. When the cross plate swings and is in a vertical state, the upper end of the ball rod abuts against the air inlet pressure plate and moves upward in the limit sleeve and slides, and the gas in the limit sleeve is delivered to the gas storage box through the second one-way air valve, and the pressure plate is pushed to move upward in the gas storage box to store the gas in the gas storage box.

[0023] When the pressure plate in the gas storage box moves up and drives the L-shaped plate to slide upward in the vertical slot, the second spring telescopic rod pulls the L-shaped rod and the deflection plate at its end to move up, ensuring that the deflection plate is located between the arc-shaped contact plate and the pulling frame;

[0024] S2: When the cross plate drives the ball bar to deflect again, the fixed plate on the ball bar deflects and squeezes the spring telescopic tube to compress, and drives the eight hinged plates to deflect at the same time and form a blooming shape, so that the arc-shaped contact plate slides in the T-shaped slide groove and squeezes the deflection plate to deflect, thereby pushing the pulling frame to move into the exhaust pipe and driving the fourth spring telescopic rod to stretch, so that the slide groove on the fourth spring telescopic rod and the C-shaped bracket are on the same vertical plane. The sealing plate is deflected by the pressure of the gas storage box and the gas in the exhaust pipe and drives the C-shaped bracket to deflect, releasing the gas in the gas storage box. At this time, the gas is transported to the gas guide inclined plate in the ring sleeve through the exhaust pipe, so that the gas guide inclined plate drives the filter screen to rotate and guides the air flow out of the inside of the filter screen, and blows the impurities adsorbed on the surface of the filter screen into the through groove to avoid clogging of the filter screen;

[0025] S3: After the gas storage box discharges its internal gas under the reset force of the first spring telescopic rod, the sealing plate is pulled back to its original position by the third spring telescopic rod, so that the end of the C-shaped bracket with the inclined surface contacts the inner rod of the fourth spring telescopic rod. At this time, the C-shaped bracket pulls the fifth spring telescopic rod to extend and then reset, and the C-shaped bracket is clamped on the inner rod of the fourth spring telescopic rod again, completing the reset and locking of the sealing plate.

[0026] S4: When the user regularly inspects and cleans the drain pipe, the user presses down on the compressor shell. When the compressor shell is squeezed, it moves downward to push the inclined tooth plate to move, which in turn drives the gear and the sealing plate to rotate, sealing the upper end of the drain pipe. As the compressor shell continues to move downward, the gas inside the compressor shell is transported along the connecting pipe to the drain pipe, increasing the air pressure inside the connecting pipe and the drain pipe, thereby avoiding blockage of the lower inner wall of the drain pipe.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, when the cross plate is blown by wind, it drives the ball club to swing, so that the second one-way air valve that the upper end of the ball club contacts moves downward and slides in the limiting sleeve, and the gas is delivered to the air guide pipe through the second one-way air valve. When the cross plate swings and is in a vertical state, the upper end of the ball club contacts the air inlet pressure plate and moves upward and slides in the limiting sleeve, and the gas in the limiting sleeve is delivered to the gas storage box through the second one-way air valve, pushing the pressure plate to move upward and slide in the gas storage box, and the gas is stored in the gas storage box for subsequent convenience.

[0029] In the present invention, the gas in the gas storage box is released through the exhaust mechanism. At this time, the gas is transported to the gas guide inclined plate in the ring sleeve through the exhaust pipe, so that the gas guide inclined plate drives the filter screen to rotate while guiding the air flow from the inside of the filter screen, blowing the impurities adsorbed on the surface of the filter screen into the through groove to avoid clogging of the filter screen.

[0030] In the present invention, when the compressed air shell is squeezed, it moves downward to push the inclined tooth plate to move, and then pushes the gear and the sealing plate to rotate, sealing the upper end of the drain pipe. Then, as the compressed air shell continues to move downward, the gas inside the compressed air shell is transported to the drain pipe along the connecting pipe, increasing the air pressure inside the connecting pipe and the drain pipe, avoiding blockage of the lower inner wall of the drain pipe.

[0069] S2: When the cross plate 813 drives the ball rod 811 to deflect again, the fixed plate 812 on the ball rod 811 deflects and squeezes the spring telescopic tube 91 to compress, and drives the eight hinged plates 92 to deflect at the same time and form a blooming shape, so that the arc-shaped contact plate 93 slides in the T-shaped slide groove 94 and squeezes the deflection plate 910 to deflect, thereby pushing the pulling frame 108 to move into the exhaust pipe 7 and driving the fourth spring telescopic rod 104 to stretch, so that the slide groove 105 on the fourth spring telescopic rod 104 and the C-shaped bracket 10 6 are on the same vertical plane, the sealing plate 102 is deflected by the pressure of the gas in the gas storage box 81 and the exhaust pipe 7 and drives the C-shaped bracket 106 to deflect, so as to release the gas in the gas storage box 81. At this time, the gas is transported to the gas guide inclined plate 63 in the ring sleeve 62 through the exhaust pipe 7, so that the gas guide inclined plate 63 drives the filter screen 64 to rotate and guides the air flow from the inside of the filter screen 64, and blows the impurities adsorbed on the surface of the filter screen 64 into the through groove 4, so as to avoid the filter screen 64 from being blocked;

[0070] S3: After the gas storage box 81 discharges its internal gas under the reset force of the first spring telescopic rod 83, the third spring telescopic rod 103 pulls the sealing plate 102 to reset, so that the end with the inclined surface of the C-shaped bracket 106 contacts the inner rod of the fourth spring telescopic rod 104. At this time, the C-shaped bracket 106 pulls the fifth spring telescopic rod 107 to stretch and reset, and the C-shaped bracket 106 is clamped on the inner rod of the fourth spring telescopic rod 104 again, completing the reset and locking of the sealing plate 102;

[0071] S4: When the user regularly inspects and cleans the drain pipe 5, the user presses down the air compressor shell 13. When the air compressor shell 13 is squeezed, it moves downward to push the inclined tooth plate 16 to move, and then pushes the gear 18 and the sealing plate 19 to rotate, thereby sealing the upper end of the drain pipe 5. As the air compressor shell 13 continues to move downward, the gas inside the air compressor shell 13 is transported to the drain pipe 5 along the connecting pipe 15, thereby increasing the air pressure inside the connecting pipe 15 and the drain pipe 5, thereby avoiding blockage of the lower inner wall of the drain pipe 5.

Then, when the cross plate (813) is blown by the wind, the ball rod (811) is driven to swing, so that the upper end of the ball rod (811) abuts against the second one-way air valve (86) and slides downward in the limiting sleeve (88), and the gas is transported to the air guide pipe (84) through the second one-way air valve (86). When the cross plate (813) swings and is in a vertical state, the upper end of the ball rod (811) abuts against the air intake pressure plate (87) and slides upward in the limiting sleeve (88), and the gas in the limiting sleeve (88) is transported to the gas storage box (81) through the second one-way air valve (86), and the pressure plate (82) is pushed to slide upward in the gas storage box (81), and the gas is stored in the gas storage box (81); When the pressure plate (82) in the gas storage box (81) moves upward and drives the L-shaped plate (97) to slide upward in the vertical groove (98), the second spring telescopic rod (96) pulls the L-shaped rod (99) and the deflection plate (910) at its end to move upward, ensuring that the deflection plate (910) is located between the arc-shaped contact plate (93) and the pulling frame (108); S2: When the cross plate (813) drives the ball rod (811) to deflect again, the fixed plate (812) on the ball rod (811) deflects and squeezes the spring telescopic tube (91) to compress, and drives the eight hinged plates (92) to deflect at the same time and form a blooming shape, so that the arc-shaped contact plate (93) slides in the T-shaped sliding groove (94) and squeezes the deflection plate (910) to deflect, thereby pushing the pulling frame (108) to move into the exhaust pipe (7) and driving the fourth spring telescopic rod (104) to stretch, so that the sliding groove (105) on the fourth spring telescopic rod (104) and the C-shaped bracket (10 6) After being on the same vertical plane, the sealing plate (102) is deflected by the pressure of the gas in the gas storage box (81) and the exhaust pipe (7) and drives the C-shaped bracket (106) to deflect, thereby releasing the gas in the gas storage box (81).
