Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design, in particular to a regulating floating hydraulic automatic gate. Background Art

[0002] In the prior art, in order to solve the problem of the organic combination of floodgate water discharge and water storage, CN104790355B floating automatic gate is provided. It does not require external power such as mechanical and electrical equipment for opening and closing, and does not require special personnel for operation and control. Instead, it utilizes the water pressure and buoyancy generated by the upstream water to accurately and timely automatically adjust the opening of the gate. Moreover, with the rise and fall of the upstream water level, the gate can gradually, automatically, accurately and instantaneously open and close to complete the water discharge and water storage processes, so that the downstream discharge maintains a dynamic balance with the upstream inflow, making the water storage, water discharge and flood control of the gate safe and reliable.

[0003] However, there are still certain technical problems in the use of the floating automatic gate. For example, due to the fixed structure of the gate, the maximum water storage depth, maximum water storage capacity, maximum opening and maximum downstream discharge of the gate are also fixed. It is impossible to adjust the water storage depth, water storage capacity, opening and downstream discharge according to the actual needs of the existing situation. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a regulating floating hydraulic automatic gate that can adjust the water storage depth, water storage capacity, opening and downstream discharge according to the actual needs of the existing situation.

[0005] The utility model is realized by the following technical solutions. A regulating floating hydraulic automatic gate is provided, which includes a gate chamber and a hollow gate located in the gate chamber. A roller groove is opened in the gate chamber, and a track is installed in the roller groove. The track is inclined to the horizontal plane and the upper end of the track faces the downstream direction. Rollers are arranged on the hollow gate, and the rollers extend into the roller groove and are movably connected with the track. A connecting groove is opened on the end face of the hollow gate facing the upstream, and a slider is arranged in the connecting groove.

[0006] During the use of the utility model, a lock chamber and a hollow gate located in the lock chamber are provided. A roller groove is formed in the lock chamber, and a track is installed in the roller groove. The track is inclined to the horizontal plane so that the upper end of the track faces the downstream direction. A roller is provided on the hollow gate. The roller extends into the roller groove and is movably connected to the track. A connecting groove is formed on the end face of the upstream end of the hollow gate, and a slider is arranged in the connecting groove. When the device is in use, by increasing the extending length of the slider from the connecting groove, the buoyancy force received by the hollow gate under the same water level can be increased, so that the rising height of the hollow gate along the track is increased, and then the opening degree of the hollow gate is increased, and the discharge flow is increased. When the slider extends to the maximum length from the connecting groove, the opening degree of the hollow gate is the largest, and the water depth in front of the gate is the smallest, which is more beneficial for flood discharge during the flood season. By reducing the extending length of the slider from the connecting groove, the buoyancy force received by the hollow gate under the same water level can be reduced, so that the rising height of the hollow gate along the track is reduced, and then the opening degree of the hollow gate is reduced, and the discharge flow is reduced. When the extending length of the slider from the connecting groove is the smallest, the buoyancy force received by the hollow gate is the smallest. At the same water level, the opening degree is the smallest, the water storage depth in front of the gate is the largest, and the water storage capacity is the largest, which is more beneficial for water storage at the end of the flood season. In this way, it is convenient for the staff to adjust the water storage depth, water storage capacity, opening degree and discharge flow according to the actual needs of the existing situation.

[0007] Preferably, a plurality of pulleys are fixedly arranged in the connecting groove at equal circumferential intervals along the slider, and the pulleys support on the slider. By fixedly arranging a plurality of pulleys in the connecting groove at equal circumferential intervals along the slider and the pulleys supporting on the slider, it is convenient to adjust the extending length of the slider in the connecting groove.

[0008] Preferably, a stopper that is circumferentially closed along the slider is fixedly provided in the connecting groove. The stopper is located on the side of the pulley away from the bottom of the connecting groove. A rubber ring fixedly connected to the inner sidewall of the connecting groove is provided on the side of the stopper away from the pulley. A plurality of pressure rods that are equidistantly distributed along the circumference of the slider are provided on the side of the rubber ring away from the stopper. One end of the pressure rod presses on the rubber ring, and the other end of the pressure rod extends horizontally out of the connecting groove in the direction away from the rubber ring and is connected to a support plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific embodiments.

[0017] Such as Figures 1 - 2The regulated floating hydraulic automatic gate of the present utility model shown in the figure includes a gate chamber 7 and a hollow gate 4 located in the gate chamber 7. A roller groove 5 is provided in the gate chamber 7, and a track 6 is installed in the roller groove 5. The track 6 is inclined to the horizontal plane and the upper end of the track 6 faces downstream. Rollers 2 are provided on the hollow gate 4, and the rollers 2 extend into the roller groove 5 and are movably connected to the track 6. A connection groove 9 is provided on the end face of the upstream end of the hollow gate 4, and a slider 1 is provided in the connection groove 9.

[0018] By fixedly installing a number of pulleys 8 equidistantly distributed along the circumferential direction of the slider 1 in the connection groove 9, and the pulleys 8 are supported on the slider 1, it is convenient to adjust the extension length of the slider 1 in the connection groove 9. By fixedly installing a circumferentially closed stop block 14 along the circumferential direction of the slider 1 in the connection groove 9, the stop block 14 is located on the side of the pulley 8 away from the bottom of the connection groove 9. A rubber ring 15 fixedly connected to the inner side wall of the connection groove 9 is provided on the side of the stop block 14 away from the pulley 8. A number of pressure rods 13 equidistantly distributed along the circumferential direction of the slider 1 are provided on the side of the rubber ring 15 away from the stop block 14. One end of the pressure rod 13 presses on the rubber ring 15, and the other end of the pressure rod 13 extends horizontally out of the connection groove 9 in the direction away from the rubber ring 15 and is connected to a support plate 11. A connection plate 12 fixedly connected to the notch of the connection groove 9 is provided between the support plate 11 and the connection groove 9. A threaded rod 10 is provided on the side wall of the support plate 11 away from the connection plate 12. The threaded rod 10 extends horizontally towards the connection groove 9 through the support plate 11 and is rotatably connected to the connection plate 12. By rotating the threaded rod 10, the support plate 11 is driven to move towards the connection groove 9 on the threaded rod 10, so that the pressure rod 13 and the stop block 14 cooperate to compress the rubber ring 15, so that the rubber ring 15 expands and contacts the side wall of the slider 1, thereby preventing water from entering the connection groove 9 and protecting the structures such as the pulley 8 in the connection groove 9, and avoiding rust and other situations caused by long-term contact with water. By providing a telescopic device 3 on the hollow gate 4 to drive the slider 1 to expand and contract, the telescopic device 3 can be used to conveniently adjust the extension length of the slider 1 in the connection groove 9 by the staff. By arranging the telescopic device 3 on the upper end face of the hollow gate 4 and fixedly connecting the piston rod end face of the telescopic device 3 to the slider 1, while facilitating the staff to adjust the extension length of the slider 1 in the connection groove 9, it can avoid rust and other situations caused by the telescopic device 3 contacting water for a long time. By providing water stops 18 between the hollow gate 4 and the bottom plate of the gate chamber 7 and between the bottom plate of the hollow gate 4 and the bottom surface of the roller groove 5, water leakage can be prevented. By providing a hydraulic damping device 17 in the roller groove 5, the vibration of the hollow gate 4 can be slowed down. By providing a truss support structure 19 in the cavity of the hollow gate 4, the inside of the hollow gate 4 can be supported. The rollers 2 are placed on the track 6 so that the rollers 2 are movably connected to the track 6. The rollers 2 can roll on the track 6 and rise or fall along the track 6 to reduce the frictional resistance.

[0019] Combined with the attachedFigures 1 - 2It can be seen that the usage method of the utility model is as follows: The telescopic device 3 drives the slider 1 to move on the pulley 8 in the connecting groove 9, so that the slider 1 extends out of the connecting groove 9 by a certain length. When the slider 1 extends out of the connecting groove 9 to a certain length, as the upstream water inflow increases, the water level in front of the hollow gate 4 rises to a certain height, and the buoyancy and water pressure exerted by the upstream water on the hollow gate 4 also increase. When the component force of the resultant force of the two forces on the track 6 is greater than the component force of the self-weight of the hollow gate 4 on the track 6, the roller 2 will roll on the track 6, thereby driving the hollow gate 4 to move obliquely upward along the track 6, and the gate opens. Water is discharged downstream through the gap between the gate and the gate chamber 7. When the upstream water inflow maintains a certain amount and no longer changes, the upstream water source water level remains unchanged, the position of the hollow gate 4 remains unchanged, then the discharge flow rate of the hollow gate 4 remains unchanged and is equal to the upstream water inflow. The water level in front of the hollow gate 4 remains stable, the hollow gate 4 is in a balanced state, and the opening degree of the hollow gate 4 remains stable. If the upstream water inflow further increases, the water level in front of the hollow gate 4 will further rise, and the buoyancy and water pressure exerted by the upstream water on the hollow gate 4 will also increase, and the hollow gate 4 will further rise, causing the discharge flow rate to further increase. If when the upstream water inflow increases to a certain amount and no longer changes, the water level in front of the hollow gate 4 remains stable, and the discharge flow rate of the hollow gate 4 is equal to the upstream water inflow, then the hollow gate 4 will be in a balanced state again, and the opening degree of the hollow gate 4 will remain stable; when the water inflow increases to a certain extent and the water level in front of the hollow gate 4 rises to a certain height, the gate will open completely. At this time, the opening degree of the hollow gate 4 reaches the maximum, increasing the discharge capacity further to well meet the need of flood discharge. When the upstream water inflow decreases, the water level in front of the hollow gate 4 will drop accordingly, causing the upstream water pressure and the buoyancy received by the hollow gate 4 to decrease. Under the action of the self-weight of the hollow gate 4, the roller 2 rolls on the track 6, and the hollow gate 4 moves obliquely downward along the track 6, thereby reducing the opening degree of the hollow gate 4 and thus reducing the discharge flow rate; when the upstream water inflow decreases to a certain amount and no longer changes, the water level in front of the hollow gate 4 remains stable, the discharge flow rate of the hollow gate 4 is equal to the upstream water inflow and remains unchanged, then the hollow gate 4 will be in a balanced state again, and the opening degree of the hollow gate 4 remains stable; when the upstream water inflow further decreases, the water level further drops, and the forces exerted by the upstream water pressure and buoyancy on the hollow gate 4 in the direction of the track 6 are further smaller than the force generated by the self-weight of the hollow gate 4, causing the hollow gate 4 to continue to move obliquely downward on the track 6, further reducing the opening degree of the hollow gate 4, and thus further reducing the discharge flow rate; when the upstream water inflow decreases to a certain extent and the water level in front of the hollow gate 4 drops to a certain height, the forces exerted by the upstream water pressure and buoyancy on the hollow gate 4 in the direction of the track 6 are further smaller than the force generated by the self-weight of the hollow gate 4, and the hollow gate 4 automatically closes under the action of its own weight to maintain the water storage state.If the upstream water inflow increases again, the hollow gate 4 will automatically open again to discharge the excess water. If the water inflow decreases, the hollow gate 4 will automatically close again, repeating this cycle. The telescopic device 3 drives the slider 1 to move on the pulley 8 in the connecting groove 9, increasing the protruding length of the slider 1 from the connecting groove 9. Since other components remain unchanged, the buoyancy force received by the hollow gate 4 at this time increases, causing the rising height of the hollow gate 4 to increase. As a result, when the water level is the same, the opening of the hollow gate 4 increases and the discharge flow rate increases; when the protruding length of the slider 1 in the connecting groove 9 is the largest, the opening of the hollow gate 4 is the largest and the water depth in front of the gate is the smallest, which is more beneficial for flood discharge during the flood season. The telescopic device 3 drives the slider 1 to move on the pulley 8 in the connecting groove 9, reducing the protruding length of the slider 1 from the connecting groove 9. Since other components remain unchanged, the buoyancy force received by the hollow gate 4 at this time decreases, causing the rising height of the hollow gate 4 to decrease. As a result, when the water level is the same, the opening of the hollow gate 4 decreases and the discharge flow rate decreases; when the protruding length of the slider 1 in the connecting groove 9 is the smallest, the buoyancy force received by the hollow gate 4 is the smallest. At the same water level, the opening is the smallest and the water storage depth in front of the gate is the largest, and the water storage capacity is the largest, which is more beneficial for water storage at the end of the flood season.
