Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and specifically relates to a water conservancy gate flow and liquid level measurement device. Background Technique

[0002] In the field of water conservancy projects, the measurement of the flow and liquid level of water conservancy gates is an important link to ensure the rational distribution of water resources, flood control and drainage, and shipping safety. Accurately and real-time monitoring the flow and liquid level of water conservancy gates is of great significance for ensuring the safe operation of water conservancy projects, optimizing the distribution of water resources, and preventing natural disasters. However, there are still many challenges in the measurement accuracy and adaptability of existing water conservancy gate flow and liquid level measurement devices. A water channel water flow measurement device is disclosed in the publication number CN218822540U. The device is beneficial to more accurately measure the liquid level in the water channel through the arranged inner cylinder and outer cylinder, and thus is beneficial to more accurately calculate the water flow in the water channel. However, since the floating of the float assembly in the water is affected by various factors such as water flow velocity, waves, and wind direction, and the fixed connection between the flow velocity sensor and the float assembly through the mounting rod means that the sensor cannot be adaptively adjusted with the water flow fluctuations, which further exacerbates the measurement error. Especially in the case of large water level fluctuations or sharp changes in water flow velocity, this fixed connection design is more likely to lead to inaccurate measurements.

[0003] Therefore, we propose a water conservancy gate flow and liquid level measurement device to improve the measurement accuracy. Content of the Utility Model

Specific embodiments

[0017] The following further describes the present utility model with reference to the accompanying drawings.

[0018] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: A water conservancy gate flow and liquid level measurement device, including a gate frame 1 and a gate 2. The gate frame 1 is fixed in the river channel and is hermetically connected to the dam body on both sides. The top of the gate frame 1 is fixedly connected to an equipment room 4 through a support column 3. A winch 5 for driving the gate 2 to lift is arranged in the equipment room 4. A steel cable 6 is arranged between the winch 5 and the top of the gate 2. A hook for connecting the steel cable 6 is arranged at the top of the gate 2.

[0019] A support frame 7 is fixedly connected to the top of the gate frame 1 near the upstream side. The length direction of the support frame 7 is perpendicular to the surface of the gate 2. A liquid level gauge 8 is fixedly connected to the surface of the support frame 7. A telemetry main control terminal 9 and a wireless communication device 10 are also arranged in the equipment room 4. A lifting device 11 is vertically and fixedly connected to the surface of the gate 2 near the downstream side. The movable end of the lifting device 11 is fixedly connected to a mounting plate 12. A flowmeter 13 is fixedly connected to the bottom of the mounting plate 12. The liquid level gauge 8 and the flowmeter 13 are in communication connection with the telemetry main control terminal 9. The telemetry main control terminal 9 is in communication connection with the wireless communication device 10. The wireless communication device 10 supports GPRS, 4G and Ethernet communications. The liquid level gauge 8 and the flowmeter 13 transmit the detected liquid level and flow information to the telemetry main control terminal 9. The telemetry main control terminal 9 transmits the measurement data to the control center through the wireless communication device 10.

[0020] An industrial computer 15 for controlling the winch 5 and the lifting device 11 is also provided in the equipment room 4. The lifting device 11 includes a motor 111 and a fixed shell 112. The motor 111 is fixed to one side of the top of the gate 2, and the fixed shell 112 is fixed to the surface of the gate 2 close to the downstream side. A screw rod 113 is rotatably connected in the fixed shell 112. The top end of the screw rod 113 extends to the top of the fixed shell 112 and is fixedly connected to a first synchronous wheel 114. The output shaft end of the motor 111 is fixedly connected to a second synchronous wheel 115. A synchronous belt 116 is transmission-connected between the first synchronous wheel 114 and the second synchronous wheel 115. A threaded block 117 is threadedly connected to the surface of the screw rod 113. A lifting arm 118 that slides along its length direction is provided on the surface of the fixed shell 112. One side of the threaded block 117 is fixedly connected to the surface of the lifting arm 118. The motor 111 drives the screw rod 113 to rotate through the synchronous belt 116, thereby driving the lifting arm 118 to move up and down through the threaded block 117.

[0021] After the industrial computer 15 controls the gate 2 to rise a distance L1, it controls the lifting device 11 to move the flow meter 13 to a position L2 from the bottom of the gate 2. The moving distance can be controlled by controlling the number of rotations of the motor in the winch 5 and the lifting device 11, where L2 = (0.3-0.6) * L1. The water immersion depth of the flow meter 13 can be adjusted as needed. Since the flow meter 13 is fixed in a fixed position, the accuracy of the water flow measurement is guaranteed.

[0022] A first protective cover 14 for protecting the flow meter 13 is arranged at the bottom of the mounting plate 12, and a through hole is arranged on the surface of the first protective cover 14. A second protective cover 17 for protecting the liquid level meter 8 is arranged on the surface of the support frame 7. The second protective cover 17 is a sealing cover and a measuring hole is arranged at the bottom.

[0023] A mounting rod 18 is fixedly connected to one side of the inner wall of the gate frame 1, and a guide rod 19 is fixedly connected to one end of the mounting rod 18. A sliding sleeve 20 is slidably connected to the surface of the guide rod 19, and a fixed cylinder 21 is fixedly connected to one side of the sliding sleeve 20. A buoyancy box 16 is fixedly connected inside the fixed cylinder 21. The buoyancy box 16 ensures that the fixed cylinder 21 changes with the water level. The center of the fixed cylinder 21 is located directly below the center of the liquid level meter 8. The liquid level meter 8 is a radar liquid level meter. The liquid level meter 8 can be a commercially available H1600 radar water level meter. The telemetry main control terminal 9 selects the telemetry main control terminal adapted thereto. The fixed cylinder 21 is provided to reduce the influence of water surface waves on water level measurement, thereby improving measurement accuracy.

[0024] The inner wall of the gate frame 1 is provided with a sealing frame 23 adapted to the gate 2, thereby improving the sealing performance.

[0025] The cross-section of the guide rod 19 is a rectangular structure, and the cross-section of the sliding sleeve 20 is a rectangle adapted to the guide rod 19. The set rectangular structure prevents the fixed cylinder 21 from rotating around the guide rod 19, thereby ensuring that the center of the fixed cylinder 21 is directly below the center of the liquid level gauge 8.
