Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water conservancy monitoring technology, specifically relating to an irrigation canal system monitoring device. Background Technology
[0002] In the management and maintenance of irrigation canal systems, real-time monitoring of parameters such as water level, flow velocity, and water quality is crucial. Water level is a fundamental indicator of the amount of water in the canal; proper water level control ensures the effective distribution and utilization of irrigation water, preventing water waste. Water levels that are too high or too low can lead to poor irrigation results and even cause canal damage or other problems. Flow velocity refers to the speed at which water flows through the canal. Appropriate flow velocity ensures uniform water distribution, preventing sedimentation and blockage caused by excessively slow flow, or erosion and scouring caused by excessively fast flow. Monitoring and controlling flow velocity is essential for maintaining canal stability and extending its service life. Water quality directly affects the growth and health of crops. Good water quality promotes healthy crop growth, while severely polluted water can lead to crop diseases and reduced yields. Therefore, monitoring and managing water quality is a vital link in ensuring irrigation effectiveness and agricultural product quality.
[0003] Existing irrigation canal management typically relies on monitoring systems that use fixed-location sensors. These sensors are usually installed along the canal or within it, such as in open channel flow monitoring systems. These systems use flow meters and sensors installed in the waterway to measure key parameters like flow velocity and water level in real time. However, this installation method only monitors hydrological parameters near the installation point. Due to environmental factors (such as water erosion and sediment deposition) and limitations in equipment accuracy, the monitoring range of fixed-location sensors is limited, potentially failing to provide accurate and stable data for the entire irrigation canal system, thus affecting the precise assessment of water quality. Summary of the Invention
[0004] In order to solve the problems existing in the prior art, the purpose of this utility model is to provide an irrigation canal system monitoring device that can flexibly move and accurately position the monitoring components above the irrigation canal system, thereby expanding the monitoring range and improving the comprehensiveness and accuracy of the monitoring.
[0005] The technical solution of this utility model is:

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.

[0033] See Figures 1 to 5 As shown, in order to enable flexible movement and precise positioning of the monitoring component 1 above the irrigation canal system, thereby expanding the monitoring range and improving the comprehensiveness and accuracy of monitoring, this embodiment provides an irrigation canal system monitoring device, including a monitoring component 1, a mounting bracket, a moving component 4, and a mounting platform 5. The monitoring component 1 includes a water level sensor, a water flow sensor, and related distance sensors for measuring data such as water flow and water level in the irrigation canal system. The mounting bracket includes a crossbeam 2 and columns 3 fixed at both ends of the crossbeam 2. The moving component is installed at the bottom of the columns 3. In use, the crossbeam 2 is supported by the columns 3 at both ends and spans across the irrigation canal system. At the same time, the moving component at the bottom of the columns 3 facilitates the movement of the crossbeam 2 along the direction of the irrigation canal system. Preferably, the crossbeam 2 adopts a multi-connection end design, with adjacent connecting sections spliced together by bolts. In this way, the crossbeam 2 can adapt to irrigation canals of different widths. To ensure the installation reliability of the crossbeam 2 and the width design specifications of the comprehensive irrigation canal system, the span of the crossbeam 2 is generally designed to be within 12m. Furthermore, the design of the crossbeam 2 allows the monitoring component 1 to move in the Y direction of the irrigation canal system by moving the installation positions of the two side columns 3, that is, the crossbeam 2 to move in the direction of water flow in the irrigation canal system.
[0034] See Figure 2 and Figure 3As shown, the moving component 4 is mounted on the crossbeam 2. The moving component 4 also includes a pulley system, a pull rope 43, and a drive unit 44. The pulley system consists of at least two active fixed pulleys 42, which are located at both ends of the crossbeam 2. The pull rope 43 is connected end to end and is wound around the two active fixed pulleys 42 respectively. Preferably, the pull rope 43 is wound with a sufficient amount of releasable pull rope 43 on each active fixed pulley 42, thereby fixing the moving plate 41 to the pull rope 43, and the moving plate 41 is slidably connected to the crossbeam 2. There can be one drive unit 44, which is connected to one of the active fixed pulleys 42. Alternatively, there can be two drive units 44, with the output shafts of each drive unit 44 connected to an active fixed pulley 42. The drive unit 44 drives the corresponding active fixed pulley 42 to rotate, and the two active fixed pulleys 42 rotate in opposite directions, which means that the winding direction of the pull rope 43 is opposite. In use, the two active fixed pulleys 42 work together to wind and release the pull rope 43 at the same time, so that the pull rope 43 forms a belt-like operation mode. This allows the moving plate 41 to move along the length of the crossbeam 2, which facilitates the adjustment of the horizontal position (X-direction displacement of the irrigation canal system) of the detection component. This enables the monitoring component 1 to reach a more precise monitoring position, improving the comprehensiveness and accuracy of the monitoring. To ensure the stability of the position adjustment of the moving plate 41 by the pull rope 43, multiple driven fixed pulleys 45 are also provided between the two active fixed pulleys 42. These driven fixed pulleys 45 are evenly distributed along the length of the crossbeam 2, and the number of driven fixed pulleys 45 can be increased or decreased according to the length of the crossbeam 2. Preferably, the drive unit 44 can be a manual crank, which manually drives the active fixed pulleys 42 to rotate, thereby moving the moving plate 41. The design of the two manual cranks allows for selection of different cranks based on the location of the monitoring component 1. The drive unit 44 can also be a motor, connecting the central shaft of the corresponding active fixed pulley 42 to the motor output shaft. When using a motor to adjust the position of the moving plate 41, both motors need to move synchronously. Preferably, the pull rope 43 and the active fixed pulleys 42 can all be made of sprockets and chains or pulleys and belts.
[0035] Furthermore, to facilitate flexible adjustment of the position of monitoring component 1 and improve the comprehensiveness and accuracy of monitoring, a slide rail is provided along the length of the crossbeam 2, and the moving plate 41 slides within the slide rail. By limiting the movement of the moving plate 41 through the slide rail, the stability of the moving plate 41 can be ensured, making it easier to stably adjust the monitoring component 1 to different positions, thereby making the monitoring component 1 maintain a more stable state during use and improving the accuracy of monitoring.
[0036] See Figures 2 to 5As shown, to facilitate flexible adjustment of the position of monitoring component 1 and improve the comprehensiveness and accuracy of monitoring, the mounting platform 5 includes a lifting bracket 51 and a lifting platform 53. The lifting bracket 51 is perpendicular to the crossbeam 2, and its upper end is connected to the moving plate 41. The lifting bracket 51 has a moving block 52 that moves vertically. The lifting platform 53 is fixed to the moving block 52, and the monitoring component 1 is mounted on the lifting platform 53. By moving the lifting platform 53 on the lifting bracket 51, the monitoring component can achieve displacement control along the Z-direction of the irrigation canal system, thus allowing the monitoring component 1 to move over a wider range above the irrigation canal system, further improving the comprehensiveness and accuracy of monitoring. A preferred design is to have multiple equally spaced screw holes on the lifting bracket 51 along the vertical direction. The moving block 52 can be fixed to any of these screw holes using bolts and nuts, thus allowing for vertical adjustment of the monitoring component 1 (in the Y direction of the irrigation canal). Alternatively, the lifting bracket 51 can be composed of a motor, a screw, and a screw sleeve. The motor is fixed to the moving plate 41, and the motor's output shaft is connected to a vertically positioned screw. A screw sleeve is fitted onto the screw, and the lifting platform 53 is fitted and fixed onto the screw sleeve. A limiting structure is provided between the screw sleeve and the screw, allowing the screw sleeve to adjust the height of the monitoring component 1 via the lifting platform 53 when the motor drives the screw to rotate. This ensures a more precise monitoring position in the vertical direction and more accurate monitoring data.
[0037] See Figure 3 and Figure 4 As shown, to facilitate flexible adjustment of the position of monitoring component 1 and improve the comprehensiveness and accuracy of monitoring, a guide assembly is also provided between the lifting support 51 and the crossbeam 2. The guide assembly includes a track 6 and a track vehicle 7. The track 6 is laid along the length of the crossbeam 2 and is fixed to the crossbeam 2; the track vehicle 7 moves along the length of the crossbeam 2 within the track 6, and the lifting support 51 is fixed on the track vehicle 7. Thus, the lifting and lowering can be stably adjusted through the sliding of the track vehicle 7 within the track 6 and the cooperation of the moving plate 41.
[0038] See Figure 2As shown, to facilitate flexible adjustment of the monitoring component 1's position and improve the comprehensiveness and accuracy of monitoring, a first distance sensor 8 is installed on the crossbeam 2 or a column 3. The first distance sensor 8 is installed at one end of the bottom of the crossbeam 2 or near the crossbeam 2 on the column 3. The first distance sensor 8 measures the distance between the monitoring component 1 and one of the columns 3 to obtain the horizontal position of the monitoring component 1 on the crossbeam 2. A second distance sensor 9 is installed on the lifting platform 53 or the monitoring component 1 to measure the distance between the monitoring component 1 and the crossbeam, thereby obtaining the vertical position of the monitoring component 1 from the irrigation canal system. By connecting the first distance sensor 8 and the second distance sensor 9 to the processor, operators can accurately adjust the monitoring component 1 in the X and Y directions of the irrigation canal system using the distance information fed back by the first distance sensor 8 and the second distance sensor 9, improving the accuracy of the monitoring position and making the monitoring data more accurate. Alternatively, both the moving component 4 and the lifting bracket 51 can be electrically driven and then electrically connected to the processor. An encoder can be set so that the conversion and processing of the detection data from the first distance sensor 8 and the second distance sensor 9 by the encoder and the processor can accurately and automatically control the target position that the monitoring component 1 needs to reach. This makes the monitoring position adjustment of the monitoring component 1 more convenient, faster and more accurate, and the detected data more comprehensive and accurate.
[0039] Furthermore, to facilitate flexible adjustment of the position of monitoring component 1 and improve the comprehensiveness and accuracy of monitoring, a movable component and a detachable anchor structure are installed at the bottom of the column 3. The movable component can employ multiple self-locking rollers. Preferably, the column 3 can also be designed as a telescopic structure. The rollers facilitate adjustment of the positioning of the entire device, and the anchor structure or positioning brackets similar to those around a crane can be used to position and secure the entire device to the ground, maintaining the stability of monitoring component 1 during operation.
[0040] Based on the above structural design analysis, this device has the following advantages:
[0041] 1. Compared to traditional fixed-position sensors that can only monitor hydrological parameters near their installation point, resulting in a limited monitoring range, this invention designs a sensor mounting platform 5 spanning the upper end of the irrigation canal system. This, combined with the movement of the crossbeam 2 in the direction of water flow in the irrigation canal system (Y-direction adjustment control), the movement of the monitoring component 1 on the crossbeam 2 by the moving component 4 (X-direction displacement control), and the height adjustment of the monitoring component 1 by the support frame (Z-direction adjustment control), achieves flexible movement and precise positioning of the monitoring component 1 above the irrigation canal system. This expands the monitoring range and improves the comprehensiveness and accuracy of the monitoring.
[0042] 2. Compared to the complex engineering work required for the installation and maintenance of traditional fixed-position sensors in irrigation canals, this invention employs mechanical structure control, reducing system complexity and reliance on electrical equipment, thereby reducing installation and maintenance costs. Furthermore, the design of this device facilitates routine inspection and maintenance by users.
[0043] 3. Compared to traditional fixed-position sensors, which may not provide accurate and stable data due to environmental factors and equipment precision limitations, this invention achieves precise positioning of the monitoring component 1 in multiple directions through a mechanical structure. Combined with the use of high-precision sensors, this improves the accuracy and reliability of data collection.
[0044] 4. Traditional fixed-position sensors pose certain safety hazards when installed in irrigation canals, such as damage due to water flow or human interference. In contrast, the suspended mounting platform 5 designed in this invention is stable and reliable, and its mechanical structure allows for rapid response and operation by the user in emergency situations, thereby reducing safety hazards.
[0045] 5. Compared to traditional fixed-location sensor systems, which struggle to adapt to varying irrigation canal systems and monitoring needs, this invention, through modular design and mechanical structure control, achieves flexible sensor mounting and positioning, as well as system scalability, enabling the platform to meet the monitoring and management needs of various irrigation canal systems.
[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
