Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, specifically a gate opening and closing control device. Background Technology

[0002] Sluice gates are structures used in water conservancy projects to control flow and regulate water levels. Closing sluice gates can block floods, tides, or raise upstream water levels to meet the needs of irrigation, power generation, navigation, aquaculture, environmental protection, industrial and domestic water use. Opening sluice gates can release floodwaters, waterlogged water, wastewater, or discharge water, and can also supply water to downstream rivers or canals. Sluice gates can be classified according to their functions as control gates, intake gates, flood diversion gates, drainage gates, tide gates, sand flushing gates, and sewage gates.

[0003] Existing gate opening and closing devices mostly adopt fixed frequency or manual control opening and closing modes. Their opening and closing actions are simple and lack dynamic adjustment capabilities. Since the water flow impact force cannot change in real time according to the siltation depth, the gate can only flush the surface sand and gravel when it is opened. The hard sand and gravel and hardened silt that have accumulated at the bottom of the dam for a long time are difficult to loosen and be discharged due to insufficient energy disturbance. Therefore, we propose a gate opening and closing control device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a gate opening and closing control device to solve the problem that the gate opening and closing action is simple and lacks dynamic adjustment capability. Because the water flow impact force cannot change in real time according to the siltation depth, the gate can only flush the surface sand and gravel when it is opened, while the hard sand and gravel and hardened silt accumulated at the bottom of the dam for a long time are difficult to loosen and be discharged due to insufficient energy disturbance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a gate opening and closing control device, including a base, two support plates fixedly connected to the upper surface of the base, a first bearing embedded in the outer surface of each of the two support plates, a screw fixedly connected to the inner ring of each of the two first bearings, a transmission rod fixedly connected to the outer surface of the screw, a power mechanism fixedly connected to the upper surface of the base, a connecting plate provided on the outer surface of the base, a first toothed plate fixedly connected to the front of the connecting plate, the first toothed plate meshing with the screw, two second toothed plates fixedly connected to the outer surface of the connecting plate, a vertical plate fixedly connected to the outer surface of the base, a plurality of second bearings embedded in the outer surface of the vertical plate, a take-up rod fixedly connected to the inner ring of each second bearing, and a gear disk fixedly connected to the outer surface of each take-up rod.

[0006] As a further improvement of this utility model: the power mechanism includes a motor, and a gearbox is fixedly connected to the upper surface of the base.

[0007] As a further embodiment of this utility model: the output end of the motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to the outer surface of the transmission rod.

[0008] As a further improvement of this utility model: two baffles are fixedly connected to the outer surface of each of the take-up rods, and a synchronizer is fixedly connected to the upper surface of the base.

[0009] As a further embodiment of this utility model: a sliding groove plate is fixedly connected to the outer surface of the vertical plate, and a slider is fixedly connected to the outer surface of the connecting plate; the inner sidewall of the sliding groove plate is slidably connected to the outer surface of the slider.

[0010] As a further embodiment of this utility model: a controller is fixedly connected to the outer surface of the vertical plate, and an ultrasonic rangefinder is fixedly connected to the bottom surface of the controller.

[0011] Compared with the prior art, the beneficial effects of this utility model include:

[0012] By opening and closing the gate at set times and dynamically adjusting the water flow speed, combined with real-time monitoring of the silt thickness using an ultrasonic rangefinder, the energy of the water flow is released in a gradient manner, effectively loosening and discharging silt and sand at different depths. This solves the problem that traditional devices can only remove surface deposits. The gearbox transmission and toothed plate meshing mechanism ensure that multiple take-up rods can simultaneously take up and release the steel rope, maintaining the smooth raising and lowering of the gate. The sliding block limit structure further improves mechanical stability and reduces the failure rate. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0021] A gate opening and closing control device includes a base 1. Two support plates 2 are fixedly connected to the upper surface of the base 1. The outer surfaces of the two support plates 2 are each inlaid with a first bearing 3. The inner rings of the two first bearings 3 are fixedly connected to a screw 5. The outer surface of the screw 5 is fixedly connected to a transmission rod 4. A power mechanism 9 is fixedly connected to the upper surface of the base 1. A connecting plate 6 is provided on the outer surface of the base 1. A first toothed plate 7 is fixedly connected to the front of the connecting plate 6. The first toothed plate 7 meshes with the screw 5. Two second toothed plates 8 are fixedly connected to the outer surface of the connecting plate 6. A vertical plate 19 is fixedly connected to the outer surface of the base 1. Multiple second bearings 11 are inlaid on the outer surface of the vertical plate 19. The inner ring of each second bearing 11 is fixedly connected to a take-up rod 13. The outer surface of each take-up rod 13 is fixedly connected to a gear disk 12.

[0022] In this embodiment, the power mechanism 9 drives the transmission rod 4 and the screw 5 to rotate. The screw 5 drives the first toothed plate 7, the connecting plate 6 and the second toothed plate 8 to move. The second toothed plate 8 drives the gear disk 12 and the take-up rod 13 to rotate. The rotation of the take-up rod 13 can wind up the steel rope, thereby raising the gate. The meshing rotation of the second toothed plate 8 and the gear disk 12 ensures that multiple take-up rods 13 can synchronously wind up and unwind the steel rope, maintaining the smooth raising and lowering of the gate.

[0023] The power mechanism 9 includes a motor 901, a gearbox 902 fixedly connected to the upper surface of the base 1, the output end of the motor 901 connected to the input end of the gearbox 902, the output end of the gearbox 902 connected to the outer surface of the transmission rod 4, two baffles 14 fixedly connected to the outer surface of each take-up rod 13, a synchronizer 10 fixedly connected to the upper surface of the base 1, a slide plate 15 fixedly connected to the outer surface of the vertical plate 19, a slider 16 fixedly connected to the outer surface of the connecting plate 6, the inner sidewall of the slide plate 15 slidingly connected to the outer surface of the slider 16, a controller 17 fixedly connected to the outer surface of the vertical plate 19, and an ultrasonic rangefinder 18 fixedly connected to the bottom surface of the controller 17.

[0024] In this embodiment, the motor 901 drives the gearbox 902, which in turn drives the transmission rod 4 to rotate. The gearbox 902 increases the torque of the motor 901. By installing baffles 14 on the outer surface of each take-up rod 13, a limiting effect is provided when the take-up rod 13 rotates to take up the line, preventing the steel cable of the gate from detaching from the take-up rod 13. By setting a slide plate 15 and a slider 16, the slider 16 slides within the slide plate 15, providing support for the connecting plate 6. The limiting structure composed of the slide plate 15 and the slider 16 further improves the mechanical stability of the device and reduces the failure rate. By setting a synchronizer 10... When using multiple motors 901, the synchronizer 10 can control the motors 901 to rotate synchronously, so that each group of take-up rods 13 can synchronously take up and release the steel rope, maintaining the smooth raising and lowering of the gate. The ultrasonic rangefinder 18 can emit ultrasonic waves and receive the rebounded ultrasonic waves, thereby measuring the height of the riverbed sediment rise. After the rise reaches the set value, a signal is sent, and the controller 17 controls the motors 901 to drive the gate to rise and fall once every three to five minutes, repeating multiple times, thereby realizing the gradient release of water flow energy, effectively loosening and discharging silt and sand at different depths, solving the defect of traditional devices that can only remove surface sediments.

[0025] Working principle: When using this device, place it on the left and right sides of the dam channel, and connect the steel rope connected to the gate to each take-up rod 13. Turn on the controller 17 and synchronizer 10, so that the motor 901 drives the gearbox 902. The gearbox 902 drives the transmission rod 4 and the screw 5 to rotate. The screw 5 drives the first toothed plate 7, the connecting plate 6 and the second toothed plate 8 to move. The second toothed plate 8 drives the gear disk 12 and the take-up rod 13 to rotate. The rotation of the take-up rod 13 can wind up the steel rope, thereby raising the gate. The raising is performed once every three minutes, and the cycle is repeated five times. After the ultrasonic rangefinder 18 detects that the accumulation of silt has reached the set height, the cycle of raising is repeated again.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
