In the practical operation of the invention, the bending section 12 is easy to be blocked, when the bending section 12 is blocked, liquid can be accumulated in the vertical section 11, the fluid pressure in the vertical section 11 is increased, so that the elastic sealing component 3 at one end of the overflow pipe 2 close to the vertical section 11 is opened, the liquid enters the overflow pipe 2 and enters the horizontal section 13 from the overflow pipe 2, the normal circulation of the liquid cannot be influenced, meanwhile, the liquid entering the overflow pipe 2 can be detected by the detecting head 4, the detecting head 4 transmits a signal to the controller 5, the controller 5 receives the signal and controls the alarm 6 to give an alarm, and then a worker can know that the bending section 12 is blocked, and meanwhile, the overflow pipe 2 is a smooth curve and is not easy to be blocked;

meanwhile, the sealing discs 7 for plugging two ends of the bent section 12 are arranged in the vertical section 11 and the horizontal section 13, when the sealing discs 7 rotate to the state of plugging the bent section 12, liquid can only enter the horizontal section 13 from the overflow pipe 2, and simultaneously, because the bent section 12 is intercepted, blockage in the bent section 12 can be cleaned, the continuous flow of the liquid cannot be influenced, and the actual production or living requirements are further prevented from being influenced;

further, after the both ends of curved segment 12 were sealed by sealed dish 7 shutoff, controller 5 will be controlled the control assembly and open sealing plate 43 this moment, and then the inside liquid of curved segment 12 and shutoff thing will be unloaded from the bottom of discharge opening 42 this moment, after the shutoff thing is unloaded, control assembly restarts control sealing plate 43 and seals discharge opening 42 once more, sealed dish 7 overturns to the state of opening the both ends of curved segment 12 simultaneously, the liquid that flows in from vertical section 11 this moment will be preferred to get into horizontal segment 13 through curved segment 12, liquid will reduce greatly at the inside pressure of vertical section 11 and be insufficient to open elastic sealing component 3, and then the inside of overflow pipe 2 at this moment is in no liquid state, will transmit the signal to controller 5 when detecting probe 4 detects the inside of overflow pipe 2 and does not have liquid, controller 5 control alarm 6 stops reporting to the police.

Specifically, as shown in fig. 4, the elastic sealing assembly 3 includes a pressure plug 31 and a first fixing plate 35, the pressure plug 31 for blocking the communication port 45 on the vertical section 11 is disposed inside the overflow pipe 2, the pressure plug 31 is designed to be a conical structure, the first fixing plate 35 is fixedly disposed inside the overflow pipe 2 at a position close to the pressure plug 31, the first fixing plate 35 is fixedly connected to the surface of the pressure plug 31 through a compression spring, and the tip of the pressure plug 31 is disposed away from the first fixing plate 35.

When the liquid in the vertical section 11 is in a normal flowing state, the pressure plug 31 will seal the communication port 45 on the vertical section 11 under the action of the compression spring fixedly connected with the pressure plug, and when the bent section 12 is blocked, the liquid pressure in the vertical section 11 will be increased, the liquid will flow into the communication port 45 on the vertical section 11 and extrude the pressure plug 31 to the direction close to the first fixing plate 35, at this time, the pressure plug 31 does not block the communication port 45 any more, and the overflow pipe 2 becomes a temporary passage for liquid transmission.

It should be noted that, the pressure plug 31 can be cylindrical, conical, etc., and is used according to the needs of those skilled in the art, the cross-sectional areas of the vertical section 11, the curved section 12 and the horizontal section 13 are consistent, when there is no blockage in the vertical section 11, the curved section 12 and the horizontal section 13, the liquid can timely sequentially pass through the vertical section 11, the curved section 12 and the horizontal section 13 and continuously flow to the next stage, at this time, the liquid does not have extra pressure to the pressure plug 31, when the curved section 12 is blocked, because there is new liquid which continuously enters in the vertical section 11, the new liquid can not timely pass through the curved section 12 and then generate pressure in the vertical section 11, at this time, three situations can occur under the action of pressure: 1. the pressure action of the liquid promotes the blockage of the bending section 12; 2. when the pressure action of the liquid is not enough to promote the blockage position of the bending section 12 to be dredged, the pressure can only act on the movable pressure plug 31 at the moment, so that the pressure plug 31 is pushed to the side far away from the communication opening 45, at the moment, a gap is generated between the communication opening 45 and the pressure plug 31, the liquid in the vertical section 11 can smoothly pass through the overflow pipe 2, and the size of the gap generated between the pressure plug 31 and the communication opening 45 is changed according to the pressure of the liquid; 3. the pressure effect of the liquid only promotes the partial unblocking of the blocked position of the curved section 12, at which time a part of the liquid circulates from the curved section 12, and at which time the amount of circulating water is reduced, while the amount of water inflow at the position of the vertical section 11 is not constant, so that the liquid in the vertical section 11 still generates pressure, and at this time, this part of the pressure acts on the pressure plug 31, so that a part of the liquid enters the overflow pipe 2.

In the case where the vertical section 11 is filled with the liquid at the maximum cross section, the elastic force of the compression spring is sufficient to push the pressure plug 31 to close the communication port 45.

Seal dish 7's middle part is run through and is equipped with dwang 8, and the one end of dwang 8 is rotated and is connected the inner wall at pipeline 1, and the groove 19 that wears out of pipeline 1 surface is worn out to the other end of dwang 8 and is linked firmly with helical gear 9, and the inside of wearing out groove 19 is equipped with the sealing member, and two sets of dwang 8 mutually perpendicular set up, with two sets of helical gear 9 intermeshing transmissions that two sets of dwang 8 are corresponding, and one of them set of dwang 8 is connected with driving motor 10 transmission.

After alarm 6 starts, controller 5 also will control driving motor 10 to start this moment, driving motor 10 will drive the rotation of one of them a set of dwang 8, helical gear 9 on a set of dwang 8 and the rotation that helical gear 9 intermeshing transmission on another set of dwang 8 can drive another set of dwang 8, and then make two sets of sealed dish 7 overturn simultaneously, sealed dish 7 upset 90 degrees can be sealed with the both ends of bend section 12, and then can clear up the shutoff thing at bend section 12 position this moment, and inside liquid can not get into bend section 12 again, and then liquid is let out from the bottom of discharge opening 42 when avoiding closing plate 43 to open and is caused the waste.

Specifically, control assembly includes conflict board 14 and electric putter 16, electric putter 16 passes through the surface of support mounting at horizontal segment 13, and electric putter 16 is close to the one end of closing plate 43 and is the expansion end, and closing plate 43 is close to the fixed surface that is equipped with conflict board 14 of electric putter 16 one end, and electric putter 16's free end is contradicted all the time on conflict board 14 and relative face with it, and the port outside that the bottom of bending section 12 is located discharge opening 42 is equipped with the upset breach 15 that supplies closing plate 43 and conflict board 14 to deflect, electric putter 16 and controller 5 electric connection.

In practical operation, after the sealing disc 7 seals the two ends of the bending section 12, the controller 5 controls the electric push rod 16 to start to contract, at this time, the limit of the electric push rod 16 on the abutting plate 14 is gradually released, the sealing plate 43 will turn over downwards under the pressure of the blocking object and the liquid inside the bending section 12 and the gravity of the sealing plate 43, and further the discharge opening 42 is opened, so that the blocking object inside the bending section 12 can be discharged, when the electric push rod 16 stretches again and gradually presses the abutting plate 14, the abutting plate 14 will drive the sealing plate 43 to turn over and seal the discharge opening 42, so as to achieve the closing of the discharge opening 42, after the closing, the driving motor 10 starts again and controls the sealing disc 7 to turn over to the state of opening the two ends of the bending section 12, and the liquid will flow through the bending section 12 again.

It should be noted that the side of the sealing plate 43 located outside the bending section 12 has no obstruction or blockage, and the blockage is blocked in the inner pipeline of the bending section 12, so that the sealing plate 43 can be normally opened and closed.

When the electric push rod 16 is in an extended state, the sealing plate 43 seals the discharge opening 42, and when the electric push rod 16 is in a contracted state, the sealing plate 43 opens the discharge opening 42.

Further, in order to promote the plugging objects in the bending section 12 to fall from the discharge opening 42, a push rod 20 for pushing the plugging objects out to the discharge opening 42 is arranged on the inner wall of the bending section 12, the push rod 20 is arranged to be closely attached to the inner wall of the bending section 12, the push rod 20 performs vertical turning motion in the bending section 12, and one end, close to the horizontal section 13, of the push rod 20 is connected with a power source.
