Technical Field
[0001] This utility model relates to the field of gate technology, specifically to an integrated gate for flow measurement and control. Background Technology
[0002] A sluice gate is a control device used to close and open a water discharge channel, allowing water stored upstream to flow downstream. Sluice gates are an important component of hydraulic structures. Their opening and closing can be used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating debris. Sluice gates are a control facility used in small reservoirs for water storage and flood control.
[0003] According to the patent announcement number CN211816092U, a control and measurement integrated gate is proposed that "by setting up a hydraulic cylinder, a rectangular tube and a gate plate, the hydraulic cylinder can drive the gate plate to move up and down, thereby facilitating the device to store and release water, simplifying control and improving the practicality of the device".
[0004] However, the above solution still has some shortcomings in actual use. The adjustment of the gate plate in this technical solution is only driven by a hydraulic cylinder. This results in poor accuracy in adjusting the height of the gate plate, which makes it impossible to meet the precise control of water flow in actual applications. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model discloses an integrated flow measurement and control gate, including a water channel structure 1, and a control gate structure 2 is provided on the inner side of the water channel structure 1.
[0024] The water channel structure 1 includes a water channel track 101, with a positioning column 102 fixedly installed on the inner wall of the water channel track 101. The mounting frame 201 is movably engaged with the inner wall of the water channel track 101 via the positioning column 102. A water exchange pipe 104 is provided on the back side of the water channel track 101. The control gate structure 2 includes a mounting frame 201, with a driving device 203 installed inside the mounting frame 201. A gate plate 204 is movably connected to the bottom end of the driving device 203. A closing opening 202 is provided inside the mounting frame 201, and the gate plate 204 is located inside the closing opening 202.
[0025] The driving device 203 includes a driving box 207. The inner wall of the driving box 207 is rotatably connected to a driving shaft 208 via a built-in motor. A collar 209 is sleeved on the surface of the driving shaft 208. A lifting plate 212 is fixedly installed on the outer side of the collar 209. The bottom end of the lifting plate 212 is fixedly connected to the top end of the gate plate 204 via a connecting rod 214.
[0026] By setting up a control gate structure 2, the built-in motor included in the drive device 203 drives the rotating shaft 208 to cause the collar 209 to drive the connecting rod 214 at the bottom of the lifting plate 212 to move up and down. This process enables the connecting rod 214 to drive the gate plate 204 to make precise height adjustments, thereby significantly improving the structure's ability to accurately control water flow. This design not only improves the structure's response speed, but also ensures that the height adjustment of the gate plate 204 can reach a very fine level by precisely controlling the position of the lifting plate 212, which is crucial for maintaining the stability and accuracy of water flow.
[0027] Specifically, the inner wall of the water channel track 101 is provided with a gate opening sensor 103 and a controller, and the controller is electrically connected to the gate opening sensor 103 and the control gate structure 2 respectively.
[0028] In this embodiment, the gate opening sensor 103 measures the opening of the gate plate 204 in real time and feeds the measurement data back to the controller so that the controller can control the operation of the built-in motor.
[0029] The gate opening sensor 103 is an existing sensor in the field, and the gate opening sensor 103 has been proposed in the integrated measurement and control gate system based on airfoil measuring flume with patent publication number CN220136404U.
[0030] Specifically, a scale bar 205 is provided on the front side of the gate plate 204, and the readings on the scale bar 205 are arranged in ascending order.
[0031] In this implementation plan, the scale bar 205 allows staff to visually observe the current height of the gate plate 204, greatly facilitating on-site operation and monitoring. The scale bar 205 further enhances the functionality and practicality of the gate structure, enabling operators to make a rough judgment of the gate plate 204's height without relying on electronic equipment.
[0032] Specifically, a guide wheel 206 is rotatably connected inside the closed opening 202, and the guide wheel 206 overlaps with the front and back sides of the gate plate 204.
[0033] In this embodiment, the design of the guide wheel 206 not only reduces the frictional resistance of the gate plate 204 during movement, making the raising and lowering of the gate plate 204 smoother, but also helps maintain the stability of the gate plate 204, preventing it from swaying or shifting during movement. This design further improves the reliability and service life of the gate plate 204.
[0034] Specifically, the surface of the drive shaft 208 is provided with a curved groove 210 that is connected end to end, and a follower rod 211 is fixedly installed on the inner wall of the collar 209. The end of the follower rod 211 overlaps with the inside of the curved groove 210.
[0035] In this embodiment, the sliding of the follower rod 211 inside the curved groove 210 allows the collar 209 to move up and down with the rotation of the drive shaft 208. This design not only achieves smooth lifting and lowering of the lifting plate 212, but also, through the shape design of the curved groove 210, allows for further control of the lifting speed and acceleration of the lifting plate 212, thereby achieving precise control over the height adjustment of the gate plate 204.
[0036] Specifically, a slide rod 213 is fixedly connected inside the drive box 207, and the slide rod 213 is slidably connected to the inside of the lifting plate 212.
[0037] In this embodiment, the sliding rod 213 provides stable guidance and support for the lifting plate 212, ensuring that it does not deviate or tilt during lifting. This design further enhances the stability and accuracy of the gate plate 204's lifting, helping to maintain precise control of water flow. Simultaneously, the sliding connection between the sliding rod 213 and the lifting plate 212 reduces friction and wear, extending the equipment's service life.
[0038] Specifically, a gear ring 215 is fixedly sleeved on the surface of the drive shaft 208, and a rack 217 is slidably connected inside the drive box 207 through an electric push rod 216. The rack 217 is located behind the gear ring 215.
[0039] In this embodiment, the electric actuator 216 is designed to provide driving force for the rack 217, enabling it to slide within the drive housing 207. The engagement of the rack 217 with the gear ring 215 provides an additional braking or locking mechanism for the drive shaft 208, preventing accidental movement of the lifting plate 212 and the gate plate 204 due to external forces. When an emergency stop or fixation of the gate plate 204 height is required, the electric actuator 216 can push the rack 217 to engage tightly with the gear ring 215, thus preventing further rotation of the drive shaft 208. This design not only improves the safety of gate plate 204 height adjustment but also enhances the stability and reliability of the entire gate structure. Furthermore, precise control of the electric actuator 216 allows for fine-tuning of the gate plate 204 height, further improving the accuracy and flexibility of water flow control.
[0040] In use, the operator can start the built-in motor via the controller, which drives the drive shaft 208 to rotate. Simultaneously, the end of the follower rod 211 tightly engages with the interior of the curved groove 210. This structural design allows the follower rod 211 to slide according to the specific shape of the curved groove 210. This sliding motion, in turn, drives the collar 209 and the lifting plate 212 to perform lifting movements. The lifting plate 212 is fixedly connected to the gate plate 204 via a connecting rod 214. Therefore, the lifting movement of the lifting plate 212 is directly transmitted to the gate plate 204, thereby achieving precise adjustment of the height of the gate plate 204.
[0041] The gate opening sensor 103 measures the opening degree of the gate plate 204 in real time and feeds the measurement data back to the controller so that the controller can control the operation of the built-in motor.
[0042] When it is necessary to stop or adjust the height of the gate plate 204, the operator can send a signal to the electric push rod 216 via the controller. The electric push rod 216 then starts and pushes the rack 217 forward until the rack 217 is tightly engaged with the toothed ring 215. This engagement effectively locks the rotation of the drive shaft 208, thereby preventing accidental movement of the lifting plate 212 and the gate plate 204. If the height of the gate plate 204 needs to be readjusted, the controller can be used to control the electric push rod 216 to move in the opposite direction, disengaging the rack 217 from the toothed ring 215, thus restoring the rotation function of the drive shaft 208. This design not only improves the safety and stability of the gate plate 204 height adjustment, but also enables the entire gate structure to respond quickly to emergencies, effectively avoiding safety accidents that may be caused by accidental movement of the gate plate 204.
[0043] In summary, this integrated flow measurement and control gate, by setting up a control gate structure 2, utilizes the built-in motor included in the drive device 203 to drive the rotating shaft 208, which in turn drives the collar 209 to drive the connecting rod 214 at the bottom of the lifting plate 212 to move up and down. This process allows the connecting rod 214 to drive the gate plate 204 to make precise height adjustments, thereby significantly improving the structure's ability to accurately control water flow. This design not only improves the structure's response speed, but also ensures that the height adjustment of the gate plate 204 can reach a very fine level by precisely controlling the position of the lifting plate 212, which is crucial for maintaining the stability and accuracy of water flow.
