[0025] The following is a further specific description of the technical solution of the present invention through embodiments and in combination with the drawings.

[0026] The double-horizontal reverse-buckling bottom-shaft-driven flap seat gate of the present invention includes a gate 1, a reverse-buckling locking device 2, a working opening and closing device 3, a lifting opening and closing device 4, a maintenance locking device 5, a civil engineering foundation 6, etc.

[0027] AsFigure 6 As shown in the figure, the civil engineering foundation 6 is composed of side piers 61 on both sides and a bottom plate 62, and is used to support and position equipment. Fixed grooves and maintenance grooves are provided on the side piers 61 on both sides. A number of U-shaped hinge seats 63 are arranged on the bottom plate 62 of the civil engineering foundation 6 for socketing the bottom shaft of the gate 1, facilitating the fixation and rotation of the gate. A number of support piers 64 are arranged on the bottom plate 62 of the civil engineering foundation 6 for padding the gate in the horizontal position to avoid the influence of slight siltation on the opening of the gate. The top of the side pier 61 is stepped.

[0028] Combined with Figures 1 to 3 As shown in the figure, the gate 1 is composed of a gate body 15, strong side beams 11, top cantilever wheels 12, bottom cantilever wheels 13, rubber flexible connections 14, water breakers 16, a bottom shaft 17, and a water stop device 18.

[0029] The gate body 15 is composed of channel steel as the horizontal secondary beam 153, variable cross-section welded T-shaped steel as the vertical main beam 152, and welded T-shaped steel as the bottom transverse main beam 151. All the above components are welded to the back of the panel 154. A water breaker 16 is provided at the top of the gate body 15, which is used to break the water surface balance of the internal and external air pressures when water passes over the top of the gate. Strong side beams 11 are provided on both sides of the gate body 15. The whole is a welded H-shaped steel with a hollowed-out and perforated back side, which is convenient for anti-corrosion work and the installation of the top cantilever wheels 12. A rubber flexible connection 14 is used between the strong side beams 11 and the gate body 15 to form a complete water sealing surface as a whole. The strong side beams 11 and the gate body 15 are both welded to the bottom shaft 17. The contact position between the bottom shaft 17 and the U-shaped hinge seat 63 is wrapped with a stainless steel protective layer, which plays the role of reducing the friction coefficient and extending the service life. See Figure 1 and Figure 2 As shown in the figure, bottom cantilever wheels 13 are installed at both ends of the bottom shaft 17, and after installation, they are always located at the fixed groove position inside the civil engineering foundation 6, playing the role of limiting the movement of the gate. A water stop device 18 is arranged on the front surface of the panel 154 of the gate. As Figure 3 shown in the figure, it is composed of a water stop seat 181, a support strip 182, and an O-shaped water stop rubber strip 183 as a whole. The water stop device 18 can ensure that after the O-shaped water stop rubber strip 183 is pre-pressed in place, the support strip bears the force, ensuring the water stop effect while using hard contact force transmission to extend its service life. At the same time, the socketed arrangement is more convenient for the replacement of the O-shaped water stop rubber strip 183 in the later stage.

[0030] Combined with Figures 4 to 5As shown in the figure, the working opening and closing device 3 is composed of a working hydraulic cylinder 31 and a working base 32. The working base 32 is installed at the top of the side pier of the civil engineering foundation 6. The working hydraulic cylinder 31 is a swing cylinder, connected to a hydraulic power source. The suspension point of the working hydraulic cylinder 31 is connected to the top cantilever wheel 12 of the gate, and can drive the gate 1 to make a sector motion around its bottom shaft 17. The lifting opening and closing device 4 is composed of a lifting hydraulic cylinder 41 and a lifting base 42. The lifting base 42 is installed at the top of the side pier of the civil engineering foundation 6, and is arranged in a staggered manner with the working base 32. The lifting hydraulic cylinder 41 is a fixed cylinder, connected to a hydraulic power source. The suspension point of the lifting hydraulic cylinder 41 is connected to the bottom cantilever wheel 13 of the gate, and can drive the bottom shaft to make a vertical lifting motion.

[0031] The reverse buckle locking device 2 is composed of a reverse buckle hydraulic cylinder 21, a reverse buckle opening and closing base 22, a hook-shaped lock 23, and a lock base 24. The reverse buckle opening and closing base 22 and the lock base 24 are installed at the top step of the civil engineering foundation 6. The reverse buckle hydraulic cylinder 21 is a swing cylinder, and its tail rotates around the reverse buckle opening and closing base 22, connected to a hydraulic power source. The suspension point of the reverse buckle hydraulic cylinder 21 is connected to the back ear of the hook-shaped lock 23, and drives the hook-shaped lock 23 to make a sector motion around the lock base 24 for locking the gate 1 in the upright state.

[0032] The maintenance locking device 5 is composed of a fixed hydraulic cylinder 52, a maintenance pin 51, and a maintenance base 53. The maintenance base 53 is installed at the maintenance slot of the civil engineering foundation 6. The fixed hydraulic cylinder 52 is connected to a hydraulic power source. The suspension point of the fixed hydraulic cylinder 52 is connected to the maintenance pin 51. During operation, the fixed hydraulic cylinder 52 drives the maintenance pin 51 to make a horizontal motion for locking the gate 1 in the maintenance state.

[0033] Combined with Figures 7 - 8, the working principle of the gate is explained as follows:

[0034] The gate is usually in the fully open state. At this time, the gate 1 lies flat at the bottom of the civil engineering foundation 6. The bottom shaft 17 of the gate 1 is stuck in the U-shaped hinge seat 63, and the top of the gate body 15 is supported at the bottom sill support pier 64. All opening and closing equipment is in the pressure-relieved and non-operating state.

[0035] Process of the gate from fully open to fully closed state: The working opening and closing device 3 is powered on and operates. The working hydraulic cylinder 31 contracts, driving the gate 1 to rotate around the bottom shaft 17. The bottom shaft 17 is restricted by the U-shaped hinge seat 63 and remains in a fixed position. When the gate 1 rotates to the upright position, the reverse buckle locking device 2 is powered on and operates. The reverse buckle hydraulic cylinder 21 drives the hook-shaped lock 23 to rotate to lock the gate.

[0036] Process from fully open gate state to scouring and silting state: The working hoisting device 3 is powered on to work, driving the gate 1 to rotate counterclockwise slightly and then maintaining pressure, unloading the hook-shaped locking device 23, starting the reverse locking device 2 to unlock the hook-shaped locking device 23. At this time, the lifting hoisting device is started to drive the bottom shaft to rise slightly and then maintain pressure, and scouring and silting are completed by the flow through the bottom of the gate.

[0037] Process from fully open gate state to maintenance state: The working hoisting device 3 is powered on to work, driving the gate 1 to rotate counterclockwise slightly and then maintaining pressure, unloading the hook-shaped locking device 23, starting the reverse locking device 2 to unlock the hook-shaped locking device 23. The working hoisting device 3 is powered on to work, driving the gate 1 to rotate clockwise around the bottom shaft 17 until the top cantilever wheel 12 reaches point A. The working hoisting device 3 maintains pressure. The lifting hoisting device 4 is powered on to work, driving the bottom shaft 17 to lift vertically. The gate 1 rotates slightly counterclockwise during the lifting process until the top cantilever wheel 12 reaches point B. The lifting hoisting device 4 maintains pressure. The working hoisting device 3 slowly releases pressure to drive the gate body to rotate clockwise until the top cantilever wheel 12 reaches the maintenance platform point C. At this time, the maintenance locking device 5 is powered on to work, and the maintenance pin 51 moves horizontally to the lower part of the wheel shaft of the bottom cantilever wheel 13 to lock the gate.

[0038] During all the above movement processes, the bottom cantilever wheel 13 is located in the gate slot of the civil engineering foundation 6, providing a limiting condition for the gate 1.

[0039] The reasonable layout of the present invention can make the large-span gate more reasonably stressed and more material-saving. At the same time, the strong side beam is separated from the gate body, removing the hard constraints on both sides of the gate body, making the deformation of the gate body under the action of water pressure more reasonable. In the present invention, the working hoisting device and the lifting hoisting equipment are both arranged on the top of the pier of the civil engineering structure, which is an open-air layout and there is no difficulty in maintenance. The gate can lie flat above the river under the combined action of the working hoisting device and the lifting hoisting device, making the maintenance of the gate body more convenient. The gate of the present invention can be lifted with a small opening under the combined action of the working hoisting device and the lifting hoisting device, and scouring and silting are carried out by the flow through the bottom of the gate, and its effect is better than that of the high-pressure scouring pump equipped with the traditional bottom shaft-driven flap gate.

[0040] The embodiments described above are only used to illustrate the present invention and not to limit the scope of the present invention. Equivalent changes and modifications made by those skilled in the art to the present invention shall all fall within the scope covered by the appended claims of the present invention.
