Description

Technical Field

[0001] This utility model relates to the field of water conservancy measurement tools, and in particular to a rapid water level measurement device for water conservancy engineering channels. Background Technology

[0002] Water conservancy projects are systematic projects that regulate surface water and groundwater. Canals are artificially excavated or filled water conveyance channels in water conservancy projects. Their core function is to transport water from water sources to irrigation areas, cities, or industrial areas. Water level data measurement is crucial for predicting the arrival time of floods and formulating flood control plans. In arid or water-scarce areas, water level data directly guides water resource allocation and facilitates the monitoring of abnormal water level changes.

[0003] A search revealed that Chinese patent CN219869873U discloses a visual water level measurement device. This device addresses the common problem that water level gauges often fail to descend into wells containing pumps, pipes, and electrical wires, or even become entangled with these items, getting stuck and damaging the instrument. Furthermore, even when the gauge touches the damp well wall, a multimeter may still register a water level reading, leading to misreadings. Therefore, an infrared camera is installed at the front of the water level gauge. During measurement, the surrounding environment is monitored in real-time, effectively avoiding obstacles in the well, facilitating rapid water level measurement, and protecting the water level probe.

[0004] While the above methods facilitate rapid measurement and protection of water level probes, current common measurement methods include manual observation of water gauges and fixed pressure sensors. However, these methods have certain limitations in practical applications: manual observation is inefficient and poses safety hazards; fixed sensors are susceptible to channel siltation, aquatic organism attachment, and water corrosion, leading to decreased measurement accuracy and insufficient long-term stability. Although the aforementioned water level measuring devices facilitate the measurement of water levels using measuring rulers and scales, the measuring ruler is easily affected by wind during the process of lowering it to the water surface, causing the measuring head to sway and deviate, resulting in a slanted path and increasing the lowering length of the measuring ruler, which can easily lead to inaccurate water level measurement results.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] As attached Figure 1-8 As shown, one embodiment of this utility model provides a rapid water level measurement device for water conservancy engineering channels, including a measuring frame 1 with a controller installed on top for overall control and data processing. The measuring frame 1 serves as the main support for the entire device, providing a stable installation foundation for other components. A variable speed motor 2 is fixedly installed on one side of the measuring frame 1. The variable speed motor 2 has an adjustable speed function, which can flexibly control the rotation speed of its output end according to actual measurement needs. An I-beam wheel 3 is fixedly connected to the output end of the variable speed motor 2. The I-beam wheel 3 is I-shaped, which facilitates the winding and storage of the measuring ruler 4. The measuring ruler 4 is set on the outside of the I-beam wheel 3. The measuring ruler 4 is engraved with precise scales for intuitive display of water level height. Its material has a certain degree of flexibility and wear resistance to adapt to use in different environments. A counterweight 5 is provided at one end of the measuring ruler 4. The counterweight 5 is made of a high-density material, which can provide sufficient gravity for the sinking of the water level probe 6, so that it can descend smoothly to the water surface. The water level probe 6 is fixedly installed on the lower surface of the counterweight 5. As a component that directly contacts the water surface, the water level probe 6 has high sensitivity and can detect changes in water level in a timely manner and transmit the signal to the controller. In order to ensure that the water level probe 6 remains stable during the descent and avoid swaying or tilting due to external factors such as wind, a stabilizing component is provided on one side of the measuring frame 1 to make the water level probe 6 descend stably. The stabilizing component includes a connecting frame 7, which is located on one side of the I-beam wheel 3.

[0020] As attached Figure 4 As shown, the connecting frame 7 has an opening 8 inside, through which the measuring ruler 4 passes smoothly.

[0021] As attached Figure 1 As shown, two limiting rods 9 are fixedly connected to the upper surface of the counterweight 5 to limit the measuring ruler 4. The two limiting rods 9 are slidably connected inside the connecting frame 7. Correspondingly, two through slots are opened inside the connecting frame 7 for the limiting rods 9 to pass through. One end of the two limiting rods 9 is hinged to a U-shaped frame 10.

[0022] As attached Figure 5 As shown, locking grooves 11 are provided on one side of both ends of the U-shaped frame 10. The shape and size of the locking grooves 11 match the components used for locking later, which facilitates the stable connection between the limiting rod 9 and the U-shaped frame 10 and further enhances the stability of the limiting rod 9.

[0023] As attached Figure 6As shown, a mounting groove 12 is provided on one side of the top of the limiting rod 9, which provides space for the subsequent installation of other components. Two iron frames 13 are embedded in the inner wall of the mounting groove 12. The iron frames 13 enhance the structural strength of the mounting groove 12 and provide a basis for interaction with the magnetic components.

[0024] As attached Figure 7 As shown, a magnet block 14 is slidably connected inside the mounting groove 12. The magnet block 14 can slide in a specific direction within the mounting groove 12. Its magnetism can attract the iron frame 13, thereby fixing its position to a certain extent. A connecting cylinder 15 is fixedly connected to one side of the magnet block 14. The connecting cylinder 15 serves to connect and transmit force. It is slidably connected inside the mounting groove 12, ensuring the stability of the sliding of the magnet block 14. A spring 16 is fixedly connected to one side of the magnet block 14. The spring 16 is sleeved on the outside of the connecting cylinder 15. One end of the spring 16 is fixedly connected to one side of the inner wall of the mounting groove 12. When the magnet block 14 is moved by an external force, the spring 16 can undergo elastic deformation and generate elastic force, providing power for the magnet block 14 to reset. An L-shaped frame 17 is fixedly connected to one end of the connecting cylinder 15. The L-shaped frame 17 and the locking groove 11 are engaged.

[0025] As attached Figure 8 As shown, the measuring frame 1 is equipped with an adjustment component inside. The adjustment component includes a limiting groove 18, which is opened inside one side of the measuring frame 1 to provide a moving track for the subsequent sliding components. A stepper motor 19 is fixedly installed on the other side of the measuring frame 1. A lead screw 20 is fixedly connected to the output end of the stepper motor 19. The lead screw 20 serves as a transmission component, which facilitates the conversion of the rotational motion of the stepper motor 19 into linear motion, thereby facilitating the position adjustment of related components.

[0026] As attached Figure 4 As shown, the lead screw 20 is externally threaded to a square rod 21 with an internal thread that matches the lead screw 20. The square rod 21 is slidably connected inside the limiting groove 18, and the limiting groove 18 is used to limit the internal thread square rod 21.

[0027] Working principle: When using this water conservancy project channel water level rapid measurement device, first adjust according to the actual situation of the channel, start the stepper motor 19 fixedly installed on the other side of the measuring frame 1, the output end of the stepper motor 19 drives the lead screw 20 to rotate. Since the internal thread square rod 21 is threadedly connected to the lead screw 20, and the internal thread square rod 21 is slidably connected in the limiting groove 18 opened inside one side of the measuring frame 1, under the rotation of the lead screw 20, the internal thread square rod 21 moves along the limiting groove 18. At this time, the internal thread square rod 21 will drive the connecting frame 7 to move laterally, thereby adjusting the position of the measuring ruler 4 and the water level probe 6 that are about to be lowered in the opening 8, so as to adapt to channels with different distances from the shore. After adjustment, start the variable speed motor 2 fixedly installed on one side of the measuring frame 1. The output end of the variable speed motor 2 drives the I-beam wheel 3 to rotate. When the I-beam wheel 3 rotates, the measuring ruler 4 wrapped around it begins to release. Under the gravity of the counterweight 5, the water level probe 6 connected to one end of the measuring ruler 4 will move downward. During the descent of the counterweight 5 and the water level probe 6, the stabilizing component plays a crucial role. Two limiting rods 9, which are fixedly connected to the upper surface of the counterweight 5, are slidably connected to the inside of the connecting frame 7 located on one side of the I-beam wheel 3. The opening 8 inside the connecting frame 7 allows the measuring ruler 4 to pass through. This structure restricts the counterweight 5 and the water level probe 6 to move only in the vertical direction, which facilitates the guidance of the counterweight 5 and the water level probe 6 by using the limiting rods 9 and the U-shaped frame 10 during the descent of the counterweight 5 and the water level probe 6, and helps the water level probe 6 to be lowered vertically. When the water level probe 6 contacts the water surface, the controller receives a signal and stops the variable speed motor 2. At this time, the corresponding water level scale on the measuring ruler 4 is read to obtain the channel water level data, completing one water level measurement. After the measurement is completed, the variable speed motor 2 is started in reverse to make the I-beam wheel 3 rotate in the opposite direction, retracting the measuring ruler 4 and raising the water level probe 6 to the initial position, ready for the next measurement. When the measurement is completed, the water level probe 6 is reset and moved below the connecting frame 7. When the U-shaped frame 10 needs to be retracted and folded to reduce its volume, the L-shaped frame 17 is pulled outward. The L-shaped frame 17 drives the connecting cylinder 15 and the magnet block 14 to slide in the mounting groove 12 opened on one side of the limit rod 9, while compressing the spring 16. When the L-shaped frame 17 moves out of the locking groove 11 opened on one side of both ends of the U-shaped frame 10, the magnet block 14 will move to the iron frame 13 away from the hinge and attract it. At this time, the U-shaped frame 10 is released from the limit. Then push the U-shaped frame 10 to fold it to one side of the two limit rods 9. After that, it can be tied and fixed with an external binding rope to facilitate the storage of the U-shaped frame 10. When unfolding, the above operation is reversed.
