The first and second elements are indirectly connected or joined to each other.

As shown in FIG. 1 to FIG. 4 , the drainage pipe scouring interception device includes a door body 1 , an elastic member, a first control member 9 , a first floating body 11 , a second control member 17 , and a second floating body 2 . As shown in Figure 1, Figure 2, and Figure 4, the door body 1 is in a closed state, and the water in the drainage pipe cannot pass through at this time. Figures 3 and 8 show three positions of the door body opening process. When the door body 1 is in a substantially horizontal position, the door body 1 reaches the open position, that is, the lowest position in Figures 3 and 8 . In this open position, the water intercepted on the upstream side is released for the purpose of flood discharge and scouring.

The elastic member is used to keep the door body 1 in the closed position shown in Figure 1, Figure 2, Figure 4, Figure 5, Figure 7, that is, after the door body 1 overcomes the elastic force acting on the door body 1 by the elastic member, the door The body 1 can be opened, and the elastic force of the elastic component is related to the water level to be intercepted. When the set water level is reached, the force of the water pressure acting on the door body 1 opens the door body 1 and drives the door body 1 to rotate until the door body 1. 1 to its fully open open position. As shown in Figure 1, Figure 2, Figure 4, Figure 5, Figure 7, during the rotation of the door body 1, the door body 1 is inclined, and the gravity of the door body 1 also plays the role of assisting the door body 1 to open. An embodiment of the elastic component includes an adjustment assembly 6, a spring 13, a tensioning belt 14, and a tensioning wheel 15. The lower end of the tensioning belt 15 is connected to the door body 1, and the upper end is guided by the tensioning wheel 15 and then connected to the spring 13. The lower end of the spring 13 is connected to the adjusting assembly 6 , the adjusting assembly 6 is arranged on the door frame 16 , and the adjusting assembly 6 is used to adjust the tightness of the spring 13 . An embodiment of the adjustment assembly 6 includes a bolt and a joint, the bolt and the joint are rotatably connected, and the upper end of the spring 13 is connected through the joint. In the embodiment shown in the figure, the main body of the door body 1 is not connected with the tension belt 14 , and a control arm 110 is connected to one side of the door body 1 , and the height of the control arm 110 is more than half the height of the door body 1 . Low, a rod is fixed on the control arm 110 on which the lower end of the tensioning strap 14 is fitted.

As shown in FIG. 5 , the first control member 9 clamps the door body 1 in the closed position and keeps the door body 1 in the closed position, so that even if the water level rises on the upstream side of the door body 1 , the door body 1 The water pressure on the upstream side can overcome the force of the elastic member, and the door body 1 will not be opened, so it is beneficial to raise the intercepted water level. Alternatively, the elastic member can be set to be more sensitive, and the elastic force provided by it can only pull the door body 1 from its open position back to its closed position without the influence of water pressure. After the water level on the upstream side reaches the design water level, as described later, the first control member 9 will trip from the door body 1 under the action of the first floating body 11 . At this time, the spring 13 is in a state of maximum contraction, the elastic force acting on the door body 1 is very small, and the water pressure is the largest at this time, so the door body 1 will be opened quickly, as shown in Figures 2 and 8, although During the rotation of the door body 1, the spring 13 will be gradually tightened, and the elastic force acting on the door body 1 will become larger and larger. To counteract the force of the elastic member, the door body 1 will continue to open rapidly until the door body 1 reaches the lowest position. As described later, the door body 1 will be stuck by the second control member 18 at its opening position, that is, the lowest position. Even if the drainage water level drops with time and the restoring force of the elastic member acts on the door body 1, at this time, there will be no actual restoring action due to being stuck.

One way of engaging the first control member 9 with the door body 1 is to form a hook 91 , and a guide slope 92 is formed on the end side of the hook 91 , and the hook 91 hooks the upper edge of the door body 1 or the door body 1 . on other parts of the highlighted settings. The guiding inclined surface 92 makes the hook 91 resemble a bird’s beak. When the door body 1 returns, the door body 1 touches the first control member 9 along the guiding inclined surface 92, and pushes the first control member 9 to the closed position. The first control member 9 is dropped and stuck on the door body 1 .

The movement of the first control member 9 is controlled by the first floating body 11 . The first floating body 11 and the first control member 9 are connected by a linkage mechanism. There are many ways of the linkage mechanism, as long as the first floating body 11 and the hook 91 move in the same direction, that is, when the first floating body 11 moves up, The hook 91 rotates upwards and tends to trip with the door body 1. When the water level reaches the set water level, the hook 91 and the door body 1 are completely tripped; The hook 91 rotates downwards and moves to a position corresponding to the latching door 1 . An embodiment of the linkage mechanism includes a first lever 111 and a first push-pull rod 10, the first lever 111 is also pivotally connected to the door frame 16, and the first push-pull rod 10 is hinged with the first lever 111 and the first control member 9 respectively. Therefore, the first floating body 11 drives the first lever 111 , the first lever 111 prys the first push-pull rod 10 , and the first push-pull rod 10 pushes and pulls the first control member 9 to rotate.

As an optional method, a synchronization mechanism is configured for the first control member 9, and the synchronization mechanism includes a synchronization link 7 and a synchronization push-pull rod 71. The synchronization link 7 is pivotally connected to the door frame 16, and the synchronization push-pull rod 71 is connected to the synchronization The rod 7 and the first control member 9 are respectively hinged, and the synchronizing mechanism and the aforementioned linkage mechanism act together on the first control member 9, so that the first control member 9 can obtain stable rotation.

As shown in FIG. 1 to FIG. 8 , an angle of 90° is formed between the closed position and the open position of the door body 1 , but it is not limited to this and may be larger or smaller than 90°.

As shown in FIG. 3 and FIG. 5 , the second control member 18 is an L-shaped or right-angled element, and its right-angled corner is mounted on the door frame 16 through the pivot 3 , and its lower end is snapped with the control arm 110 of the door body 1 , In one embodiment, the control arm 110 corresponds to the pin 112 on its side. When the door body 1 is rotated to the open position, the lower end of the second control member 18 is locked with the pin 112 . In one embodiment, the snap between the second control member 18 and the control arm 110 is configured such that the force (including most of the force) of the control arm 110 acting on the second control member 18 is directed towards the pivot 3, and so implemented The advantage is that the second control member 18 will not be rotated. Even if a large torque is applied to cause the control arm 110 to rotate to the closed position of the door body 1, the door body 1 will not be able to be locked due to the latching of the second control member 18. Unable to turn. In another embodiment, the snap between the second control member 18 and the control arm 110 is arranged so that the force (including most of the force) of the control arm 110 acting on the second control member 18 is directed to the right of the pivot 3 The position, likewise, makes the snap so strong that the door body 1 cannot be turned into the closed position without tripping. The advantages of the foregoing embodiments also include that the second floating body 2 for driving the second control member 18 can be set very small, or the force of the second floating body 2 to drive the second control member 18 only needs to be small. The second floating body 2 is associated with the second control member 18 through a linkage mechanism. Similarly, there can be various implementations of the linkage mechanism, as long as the relative positional relationship or relative motion relationship between the second floating body 2 and the second control member 18 can be satisfied : During flood discharge and scouring, the second floating body 2 drives the second control member 18 to move to a position where it can be locked with the door body 1 as the water level rises, and after the flood discharge and scour is completed, the second floating body 2 drops with the water level and drives the second control member 18 Movement to trip with door body 1. In the embodiment shown in the figure, the linkage mechanism includes a second lever 21 , the second floating body 2 is connected to the distal end (ie, the labor-saving end) of the second lever 21 , and the second control member 18 is provided with a chute (in the (not shown in the figure), the proximal end of the second lever 21 is slidably connected to the chute, the floating of the second floating body 2 drives the second lever 21 to rotate, and the second lever 21 prys the second control member 18 to make the second control Piece 18 rotates. The second lever 21 is mounted on the door frame 16 through the bracket 4 . As shown in FIG. 3 , during flood discharge and scouring, the second floating body 2 is acted by buoyancy, and drives the second control member 18 so that the second control member 18 has a tendency to rotate against the door body 1 , that is, in the figure, it is The hour hand rotates, so that the second control member 18 can be forced to clamp the door body 1 by a small force, that is, the control arm 110 of the door body 1 is clamped.
