Description

Technical Field

[0001] The present invention relates to the technical field of water level and flow rate measurement, and more particularly to a water level and flow rate measuring mechanism. Background Art

[0002] In frontier fields such as water conservancy project construction, dynamic hydrological monitoring, and systematic ecological and environmental research, water level and flow rate measurement mechanisms, as core data acquisition equipment, shoulder the key mission of obtaining basic parameters of water bodies. Relying on its high-precision capture of water level elevation and instantaneous water flow velocity, the mechanism provides accurate and reliable data support for the formulation of comprehensive river management plans, the construction of flood prevention and disaster reduction early warning systems, and the intelligent scheduling and operation of hydropower stations. Whether it is to protect the water ecological security of the river basin, promote the scientific and optimal allocation of water resources, or even drive scientific research and innovation in the field of water conservancy, water level and flow rate measurement mechanisms play an irreplaceable cornerstone role and are important technical equipment to support the high-quality development of modern water conservancy.

[0003] However, existing water level and flow rate detection technologies have many drawbacks. At present, when measuring the water level and flow rate of rivers and lakes, the main method is to drive a boat equipped with a detector for mobile measurement, or to install a detection device at a designated location.

[0013] (3) Beneficial effects Compared with the prior art, the present invention provides a water level and flow rate measurement mechanism, which has the following beneficial effects: 1. A water level and flow velocity measuring mechanism, through the arrangement of a detection barrel, a first coil, a second coil, an antimagnetic shield, a master control circuit board, an electrode probe, a sound wave transmitter, a sound wave receiver, and a first flow stabilizing vane, enables the water level and flow velocity measuring mechanism to detect the water level and flow velocity of a water body. Through the coordinated arrangement of the first coil, the second coil, and the electrode probe, during use, according to Faraday's law, when water flows through the interior of the detection barrel, it cuts the magnetic flux lines, generating an induced electromotive force. At this time, the magnitude of the induced electromotive force is detected by the two electrode probes, and the water flow velocity is calculated using Faraday's formula. Through the arrangement of the sound wave transmitter and the sound wave receiver, the two form the effect of an acoustic Doppler flow meter, re-detecting the water passing through the interior of the detection barrel and improving the detection accuracy. The ultrasonic water level meter probe is arranged to emit ultrasonic waves downward from the bottom of the detection barrel. The water level height can be calculated based on the time interval between receiving the ultrasonic waves, thereby achieving the purpose of detecting the flow velocity and water level of the water body.

[0014] 2. This water level and flow velocity measuring mechanism, through the setting of the anti-interference module, enables the water level and flow velocity measuring mechanism to reduce the impact of water surface waves on the water level detection accuracy. Through the coordinated setting of the support rod, ball head slider, hydraulic shock absorber, spring and return spring, when there are waves on the water surface during use, the ball head slider can slide on the outer surface of the support rod, and the sliding force can be weakened by the hydraulic shock absorber and the spring, thereby reducing the impact of waves on the water level detection accuracy.

[0015] 3. This water level and flow rate measuring mechanism, through the setting of the driving module, enables the water level and flow rate measuring mechanism to have the effect of being able to move freely in the water body and reducing the entanglement of impurities on the double-blade impeller. Through the coordinated setting of the third flow-stabilizing vane, the motor and the double-blade impeller, the entire device can be driven to move in the water body during use. When impurities pass through the upper and lower sides of the third flow-stabilizing vane during the movement, they are detected by the infrared sensing switch, thereby stopping the operation of the double-blade impeller and keeping the double-blade impeller in a horizontal state with the third flow-stabilizing vane to prevent impurities from entangled in the double-blade impeller.

[0024] Specifically, the support rod 23 of the anti-interference module is fixed to the upper surface of the detection barrel 1 through the connecting seat 22, the hydraulic shock absorber 26 and the spring 27 in the slide 24 abut the ball head slider 25, the return spring 28 connects the slider and the support rod 23, the ball head seat 29 movably connects the first float 30 and the second float 32, and the drainage groove 31 is opened on the upper surface of the first float 30.

[0025] See also Figure 1 、 Figure 2 and Figure 5The driving module includes a third flow-stabilizing vane 12, the inner side wall of the third flow-stabilizing vane 12 is fixedly connected to a battery 13, a camera 14 is provided on the right side of the interior of the third flow-stabilizing vane 12, the end of which passes through the outer surface of the third flow-stabilizing vane 12, an infrared sensor switch 15 is fixedly connected to the outer surface of the third flow-stabilizing vane 12, a motor 16 is provided on the left side of the interior of the third flow-stabilizing vane 12, one end of the output shaft of the motor 16 is fixedly connected to a two-leaf impeller 17, the material of the two-leaf impeller 17 is iron, an electromagnet 18 is provided on the inner side wall of the third flow-stabilizing vane 12, the magnetic end of the electromagnet 18 is provided on the outer side of the two-leaf impeller 17, a control module 19 is provided on the inner side wall of the third flow-stabilizing vane 12, the camera 14, the infrared sensor switch 15, the motor 16 and the electromagnet 18 are all electrically connected to the control module 19 through a wire 34, the control module 19 is electrically connected to the battery 13 through a wire 34, and two infrared sensor switches 15 are provided and are symmetrically arranged up and down.

[0026] Specifically, in the third flow stabilizing wing plate 12 of the driving module, the motor 16 drives the two-blade impeller 17, the electromagnet 18 is arranged on the outside of the impeller, the infrared sensor switch 15 is symmetrically installed on the outer surface of the third flow stabilizing wing plate 12, the control module 19 coordinates the work of various components, the battery 13 provides power, and when the infrared sensor switch 15 detects impurities within a certain range, the control module 19 cuts off the power supply of the motor 16 and activates the electromagnet 18 at the same time to adsorb the two-blade impeller 17 to a horizontal position, so that the blades are parallel to the direction of water flow, reducing the risk of entanglement. After the impurities pass through for a certain period of time, the electromagnet 18 loses its magnetism and the motor 16 resumes operation. The ferromagnetic material of the two-blade impeller 17 ensures that the electromagnet 18 responds quickly. This mechanism effectively improves the anti-entanglement efficiency of the impeller. In summary, when the overall device is in use: hold the handle 33 to place the device into the river at the designated location, then use the smart device to remotely control the device, and set the wireless transmission antenna 35 inside the handle 33 to reduce interference in signal transmission. When working, the first float 30 and the second float 32 keep the detection bucket 1 below the water surface, and the two motors 16 are controlled to drive the two double-blade impellers 17 to rotate, thereby pushing the device to one end of the detection bucket 1. After moving to the designated position, detection can be carried out. During detection, the main control circuit board 5 controls the first coil 2 and the second coil 3 to work, and magnetic flux lines are generated inside the detection bucket 1. The water flowing through the inside of the detection bucket 1 will cut the magnetic flux lines and generate an induced electromotive force. At this time, the two electrode probes 6 detect the induced electromotive force, and then according to Faraday's law of electromagnetic induction, the flow rate of the water body can be calculated. When the sound wave transmitter 7 and the sound wave receiver 8 are working, the first coil 2, the second coil 3 and the electrode probe 6 stop working, and the sound wave transmitter 7 transmits ultrasonic waves to the inside of the detection bucket 1. After being captured by the sound wave receiver 8, the time interval is analyzed, and then based on Based on the size of the internal cross-section of the detection barrel 1, the amount of water passing through the device during the time period is calculated, thereby calculating the water flow velocity. Finally, the water flow velocity is remotely transmitted to the smart terminal via the wireless transmission antenna 35. The two detection methods operate alternately to avoid mutual interference. When the device moves to a specified position, the ultrasonic water level meter probe 10 can emit ultrasonic waves toward the bottom of the device. When the ultrasonic water level meter probe 10 receives the ultrasonic wave again, the water level height can be calculated based on the event interval. The data is also transmitted to the remote terminal of the smart device via the wireless transmission antenna 35. During driving, the camera 14 captures the image in front of the device to facilitate improved control. When waves are generated on the water surface, the first float 30 and the detection barrel 1 will slide relative to each other, and the ultrasonic water level meter probe 10 and the third flow stabilizing wing 12 will increase the vertical resistance of the device. When the waves impact the first float 30 and the second float 32, the detection barrel 1 tends to maintain its original position inside the water body. At this time, the ball head slider 25 will slide up and down on the outer surface of the support rod 23, squeezing the spring 27 in that direction during sliding. The spring 27 transmits the force to the hydraulic shock absorber 26, which can weaken the impact force. The setting of the two groups of hydraulic shock absorbers 26 and the spring 27 can form a state of pulling and pushing, which can better weaken the impact force of the waves. The return spring 28 drives the ball head slider 25 to its original position. The cooperation of the ball head slider 25 and the ball head seat 29 allows the first float 30 to be tilted at multiple angles within a specified range. When the waves hit, the support rod 23 and the components installed at the lower end of the support rod 23 maintain their original vertical state, effectively improving the anti-wave interference performance and making the measurement value more accurate. During the movement of the device through the driving device, when impurities in the water pass through a certain range above and below the third flow-stabilizing wing plate 12, the infrared sensor switch 15 can detect that there are impurities approaching. When impurities approach, the motor 16 stops working.The electromagnet 18 starts working, and its magnetic end generates a magnetic force on one side of the two-blade impeller 17, which attracts the two-blade impeller 17, thereby preventing the two-blade impeller 17 from continuing to rotate. At the same time, it keeps the blades of the two-blade impeller 17 and the third flow stabilizing vane 12 level, effectively preventing impurities in the water from entangled on the two-blade impeller 17 and interfering with the movement of the device.

[0027] In all the schemes mentioned above, the connection between the two parts can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be described here one by one.
