Referring to fig. 1 and 2, a flap door locking device 10 according to an embodiment of the present invention will now be described. The flap locking device 10 is installed on a drain pipe body 30, wherein the drain pipe body 30 has a drain pipe opening 31 for discharging rainwater and a drain pipe opening 32 for discharging sewage, a flap 20 is installed at the drain pipe opening 31 for closing the drain pipe opening 31 in a non-rainy period so that sewage is blocked in the drain pipe body 30 and can only be discharged from the drain pipe opening 32, and the flap locking device 10 is used for locking the flap 20 to close the drain pipe opening 31 of the drain pipe body 30.
Further, the flap valve locking device 10 includes a rotating shaft 100, a first linking member 200 and a second linking member 300, wherein the rotating shaft 100 is rotatably connected to the drain pipe body 30, the rotating shaft 100 is provided with a locking groove 110, the first linking member 200 is respectively connected to the flap valve 20 and the rotating shaft 100 in a transmission manner, so that the rotating shaft 100 rotates synchronously with the flap valve 20 through the transmission of the first linking member 200, the second linking member 300 includes a linking rod 310 and a floating block 320 disposed in the drain pipe body 30, the linking rod 310 includes a locking portion 311 corresponding to the locking groove 110, and a first connecting portion 312 respectively connected to the floating block 320 and the locking portion 311.
The operation of the flap lock mechanism 10 will now be described in detail: referring to fig. 1 (the dotted line in each figure is the current water level line in the drain pipe body 30), during a non-rain period, the water level in the drain pipe body 30 is relatively low, the flap valve 20 is in a closed state, at this time, the locking portion 311 of the linkage rod 310 just faces the locking groove 110 on the rotating shaft 100, and the locking portion 311 extends into the locking groove 110 to limit the rotating shaft 100 to rotate, so that the flap valve 20 is prevented from being accidentally opened during the non-rain period; referring to fig. 2 and 3, during a rain period, the water level in the drainage pipe body 30 gradually rises, and then the floating block 320 in the drainage pipe body 30 is driven to float upwards, and the locking portion 311 is driven by the first connecting portion 312 to leave the locking groove 110 during the floating process of the floating block 320, so that the rotation limitation of the rotating shaft 100 is removed, and at the same time, the flap valve 20 can be automatically opened or closed according to the water flow in the drainage pipe body 30.
It can be seen that the utility model provides a flap valve device and flap valve locking device 10 can prevent that flap valve 20 from opening in non-rainy period accident at non-rainy period, leads to the interior sewage of drainage pipe body 30 to flow into the river and gushes, when rainy period, can carry out automatic unblock to flap valve 20 through the water level change in drainage pipe body 30 again.
Further, in the process that the rotating shaft 300 rotates along with the opening or closing of the flap valve 20, the locking groove 110 on the rotating shaft 300 is always staggered relative to the locking portion 311, when the water level in the drain pipe body 30 drops, but the flap valve 20 is not completely closed, the locking portion 311 can only relatively slide along the arc surface of the rotating shaft 100, and cannot extend into the locking groove 110 to accidentally lock the rotating shaft 100, only after the flap valve 20 is completely closed, the locking portion 311 is aligned with the locking groove 110 again, and the locking portion 311 immediately extends into the locking groove 110 to relock the flap valve 20.
Further, the flap locking device 10 further includes a shaft sleeve 400 for mounting the rotating shaft 100, in this embodiment, the shaft sleeve 400 is disposed on an outer side wall of the top of the drainage tube 30, the rotating shaft 100 is disposed in the shaft sleeve 400, so as to achieve a rotational connection, and a connection portion of the first linkage 200 and the rotating shaft 100 and a connection portion of the shaft sleeve 400 and the rotating shaft 100 are in a staggered state all the time on a plane, so as to avoid blocking the connection of the first linkage 200 and the rotating shaft 100.
Furthermore, the flap locking device 10 further includes a shaft 500, one end of the shaft 500 is fixed to the outer sidewall of the top of the drain pipe body 30 adjacent to one end of the drain pipe opening 31, and the other end extends in a direction away from the drain pipe body 30, and a shaft sleeve 400 of the rotation shaft 100 is fixed, so as to raise the rotation shaft 100, so that the interference of the outer sidewall of the drain pipe body 30 on the first and second linkage members 200 and 300 is reduced during the movement of the first and second linkage members 200 and 300.
Further, referring to fig. 2, the linkage rod 310 further includes a second connection portion 313, two opposite ends of the second connection portion 313 are respectively connected to the first connection portion 312 and the locking portion 311, in this embodiment, the first connection portion 312 and the locking portion 311 are arranged in parallel along the floating direction of the floating block 320, and the second connection portion 313 is respectively connected to the first connection portion 312 and the locking portion 311 along the floating direction perpendicular to the floating direction of the floating block 320.
Further, the flap locking device further includes a limiting member 600, the limiting member 600 is disposed on a rotation path of the flap 20, and when the flap 20 rotates to a certain angle, the limiting member 600 abuts against an outer sidewall of the flap 20, so as to limit a maximum opening angle of the flap 20. In this embodiment, the retaining member 600 is fixed to the column 500, and in other embodiments, the retaining member 600 may also be directly fixed to the top of the outer sidewall of the drain pipe body 30.
Furthermore, a limiting through hole 710 is formed in the top of the drainage pipe body 30, a limiting pipe 720 corresponding to the limiting through hole 710 is installed, the limiting pipe 720 is disposed on the outer side wall of the drainage pipe body 30, the first connecting portion 312 extends into the mixed flow sewage pipe through the limiting pipe 720 and the limiting through hole 710 and is fixedly connected with the floating block 320, taking the view angle of fig. 2 as an example, the limiting through hole 710 is used for restricting the swing range of the first connecting portion 312 along the horizontal direction, and after the locking portion 311 is prevented from extending into the locking groove 110, the first connecting portion 312 swings unexpectedly, so that the locking portion 311 extends away from the locking groove 110, and the flapper 20 is unlocked unexpectedly.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
