Description of the drawings:

fig. 1 is a schematic view of the three-dimensional structure of the resistance-free leakage-proof square flap valve of the present invention.

The specific implementation mode is as follows:

the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.

The resistance-free anti-seepage square flap valve shown in fig. 1 is arranged on an overflow weir plate or a wall surface of a water outlet open channel water outlet and comprises a fixing frame 4, a square flap valve 2, a buoyancy tank mechanism, an anti-lock cavity 6 and a rotary connecting mechanism. The fixed frame 4 is fixed with an overflow weir plate or a wall surface of a water outlet open channel water outlet, the square flap door 2 is covered with the fixed frame 4, a sealing ring 3 is arranged on the end surface of the square flap door 2 opposite to the fixed frame 4, the square flap door 2 is rotatably connected with the top end of the fixed frame 4 through a rotary connecting mechanism, the rotary connecting mechanism comprises a positioning block 9 and a telescopic rod 1, the positioning block 9 is fixed on the square flap door 2, the telescopic rod 1 is arranged in the positioning block 9 and can slide back and forth along the positioning block 9, one end of the telescopic rod 1 is rotatably connected with the fixed frame 4, the buoyancy tank mechanism comprises a buoyancy tank 5 and a rotating arm 7, the rotating arm 7 is L-shaped, the middle corner of the rotating arm 7 is rotatably connected with a frame at the bottom of the fixed frame 4 through a pin shaft, the buoyancy tank 5 and a reverse locking cavity 6 are respectively arranged at two ends of the rotating arm 7, one end of the rotating arm 7 is arranged in the reverse locking cavity 6, the rotating arm 7 is in a rolling connection with the reverse locking cavity 6 through a roller 8, the anti-lock cavity 6 is sleeved outside the roller 8 and limits the space of the roller 8.

Touching flotation tank 5 when intaking the side water level and rising, flotation tank 5 adopts hollow structure can realize the buoyancy conversion. The buoyancy of the buoyancy tank 5 is transmitted to the thrust of the opposing flap door 2 through the end roller 8 by the rotating arm 7. The thrust transmitted by the buoyancy tank 5 to the roller 6 is required to overcome the sum of the counter pressure of the square flap door 2 and the rotational friction. The square flap valve 2 can realize the outward discharge of the internal water body after being opened without resistance. When the internal water level is removed, the square flap valve 2 is closed freely, the buoyancy tank 5 presses the anti-locking cavity 6 to close the square flap valve 2 after the gravity freely falls down, and the sealing ring 3 is sealed by nitrile rubber.
