Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides an automatic flood discharge flap steel dam gate, including a gate leaf 1, an upper support rod 4, a lower support rod 6, a platform 9, a stop rod 10, a water filling pipe 13, a gate leaf hinge 2 disposed at the bottom of the gate leaf 1, and a gate leaf hinge 3 disposed at the upper portion of the gate leaf 1.
The door leaf supporting hinge 2 is fixed on a downstream concrete bottom plate, the door leaf 1 can rotate around the door leaf supporting hinge 2, the downstream side of the upper portion of the door leaf is provided with a door leaf hinge 3, the upper support rod 4 is connected with the door leaf 1 through the door leaf hinge 3, the upper support rod 4 can rotate around the door leaf hinge 3, the other end of the upper support rod 4 is provided with a support rod hinge 5, the lower support rod 6 is connected with the upper support rod 4 through the support rod hinge 5, and the lower support rod 6 and the upper support rod 4 can rotate around the support rod hinge 5. The other end of the lower support rod 6 is connected with a lower support rod support hinge 7, the lower support rod support hinge 7 is fixed on a downstream concrete bottom plate, and the lower support rod 6 can rotate around the lower support rod support hinge 7.
Go up vaulting pole 4, lower vaulting pole 6 sets up platform 9 with the below of door leaf 1, the right side of platform 9 links to each other with platform hinge 8, platform hinge 8 is fixed on downstream concrete bottom plate, platform 9 can rotate around platform hinge 8, the supporting of platform 9 left side is on filling water pipe export 15, platform 9 with fill water pipe export 15 contact, the left side upper surface of platform 9 sets up pin hinge 11, pin 10 one end is connected on pin hinge 11 to can rotate around pin hinge 11, the other end and the contact of lower support bar 6 for support lower vaulting pole 6.
The welding has the pin stopper 12 on the vaulting pole 6 down, and when the manger plate state, pin stopper 12 can hold pin 10, prevents that pin 10 from rotating clockwise around pin hinge 11 and descending under the dead weight effect, leads to can not forming the supporting role to vaulting pole 6 down.
The inlet 14 of the water filling pipe is positioned at the upstream side of the door leaf 1, the inlet 14 of the water filling pipe is provided with a trash rack, the inlet 14 of the water filling pipe is higher than the top of the door leaf 1, and the outlet 15 of the water filling pipe is positioned at the downstream side of the door leaf 1. As shown in fig. 4, a door leaf support 16 is arranged beside the door leaf hinge 3 at the upper part of the door leaf 1, a support device 17 is correspondingly arranged on the downstream concrete bottom plate, when the door leaf 1 falls down, the door leaf support 16 is in contact with the support device 17, and the height of the support device 17 from the ground needs to ensure that the support structure is in a relaxed state when the steel dam gate falls down.
Stop lever 10 resembles the trigger on a pistol. When water is retained, no water exists in the water filling pipe 13, the upper support rod 4 and the lower support rod 6 support the door leaf 1, the stop rod 10 supports the lower support rod 6, and the flap steel dam gate is in a balanced state. When flood discharge is carried out, water is filled in the water filling pipe 13, the trigger is triggered by the pressure difference between the inlet 14 and the outlet 15 of the water filling pipe, the stop rod 19 falls down, the lower support rod 6 loses support, and the four-bar mechanism (the door leaf 1, the upper support rod 4, the lower support rod 6 and the support hinges and hinges thereof) rotates until the gate falls down.
As shown in figure 1, when the steel dam gate is in a water retaining state, the upstream impounded water level is generally not higher than the top of the door leaf 1. When the upstream water level is higher than the top of the door leaf 1 and lower than the inlet 14 of the water filling pipe, the water flow leaks downwards along the top of the steel dam gate to form a water curtain. Under the action of upstream water pressure, the upper stay bar 4 and the lower stay bar 6 have a tendency of rotating towards the inner side of the door leaf 1, at the moment, the stop lever 10 plays a role in preventing the lower stay bar 6 from rotating, and the stop lever limiting block 12 welded on the lower stay bar 6 prevents the stop lever 10 from descending, so that the stability of a supporting structure system is kept.
When the upstream water amount is larger than the lower discharge amount of the steel dam, the upstream water level rises, as shown in fig. 2, when the upstream water level rises to the height of an inlet 14 of a water filling pipe, water flow enters the water filling pipe 13 through an inlet trash rack, and then the water filling pipe 13 is filled with water, due to the pressure difference between the upper stream and the lower stream of a gate of the steel dam, the water in the water filling pipe 13 forms upward pressure at the bottom of a platform 9, the platform 9 rotates around a platform hinge 8 under the action of water pressure, the platform 9 drives a stop lever 10 to push a lower support rod 6 to rotate clockwise, and at the moment, a door leaf 1, an upper support rod 4, the lower support rod 6 and hinges thereof form a four-bar mechanism.
After the platform 9 is opened by a certain angle, the stop lever 10 is separated from the lower support rod 6, the stop lever 10 rotates to be in contact with the platform 9 under the self-weight effect (as shown in fig. 3), the four-bar mechanism rotates clockwise under the upstream hydraulic pressure effect, the gate gradually rotates and descends, the pressure difference between the upstream and the downstream of the water filling pipe 13 is also gradually reduced, and the platform 9 rotates anticlockwise around the platform support hinge 8 and descends. When the door leaf support 16 contacts with strutting arrangement 17, four-bar linkage stops the rotation, and finally the steel dam gate is crouched down, is equipped with the elastic buffer cushion on the strutting arrangement 17, can ensure not take place impact vibration when the steel dam gate is crouched down, protects the steel dam gate.
When the dam face is wide, a plurality of flap steel dam gates can be installed side by side, one gate is provided with a set of water filling pipes, and the width of each gate, the number of support rod structures, the area of the water filling pipes and the like are determined according to specific projects. When flood discharge is carried out, the horizontal sequence of the gates can be determined according to requirements, for example, when the steel dam gate in the middle of the dam face needs to be opened first, the height of the water filling pipe inlet 14 corresponding to the steel dam gate in the middle of the dam face is lower than the height of the water filling pipe inlets 14 of other steel dam gates.
After flood, a simple method is adopted, such as hoisting a support, guiding a chain and other tools to reset the gate.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
