[0002] River flow monitoring is not only crucial for hydrological monitoring and flood warning, but also involves multiple aspects such as water resource management, ecological environment protection, and water conservancy project design, and is of great significance for promoting the sustainable development of society and economy.
[0003] Currently, the velocity-area method is often used for continuous monitoring of river flow. The flow rate is calculated by measuring the flow velocity and the cross-sectional area through which the water flows. The main parameters involved are flow velocity and depth. Flow velocity is usually measured by a current meter, while depth is measured by a water gauge.
[0004] However, when using a water gauge to measure water depth, it is necessary to manually observe the moment when the measuring rod moves to the water surface, and to manually record the corresponding water gauge readings when the measuring rod moves to the water surface and riverbed. In actual measurement, this is labor-intensive, cumbersome, and has low measurement accuracy. Utility Model Content

Detailed Implementation
[0031] 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.
[0032] Example 1: As shown in the attached document Figure 1 and attached Figure 2As shown, this embodiment provides a monitoring device for water flow monitoring, including a horizontal support 1, a support plate 2, a vertical support 13, a measuring rod 6, a current meter 12, a horizontal moving device 20, a vertical moving device, a water depth measuring device, and a controller. The horizontal support 1 is set on the outside of the bridge railing of the river, and the support plate 2 is slidably connected to the horizontal support 1. The horizontal moving device 20 is set on the support plate 2, and the driving end of the horizontal moving device 20 is connected to the horizontal support 1. The vertical support 13 is connected to the outside of the support plate 2, and the measuring rod 6 is slidably connected to the vertical support 13. The vertical moving device is set on the support plate 2, and the driving end of the vertical moving device is connected to the measuring rod 6. The current meter 12 is set at the lower end of the measuring rod 6, and the water depth measuring device is set on the measuring rod 6. The current meter 12 and the water depth measuring device are both electrically connected to the controller.
[0033] Specifically, a single device is welded from U-shaped steel into a square structure. The transverse support 1 is assembled from multiple such single devices into a rectangular overall structure. The transverse support 1 is detachably installed on the outside of the bridge railing over the river. The number of single devices constituting the transverse support 1 can be increased or decreased depending on the length of the bridge. The measuring rod 6 is welded from flat steel into a long strip structure.
[0034] Specifically, the lateral moving device 20 is fixedly mounted on the surface of the support plate 2, and the driving end of the lateral moving device 20 is connected to the lateral support 1, which can drive the support plate 2 to slide along the axial direction of the lateral support 1.
[0035] The vertical support 13 is assembled into a rectangular integral structure from multiple individual devices. The vertical support 13 is movably connected to the outside of the support plate 2. Preferably, the vertical support 13 is arranged vertically perpendicular to the water surface. The measuring rod 6 is slidably connected to the vertical support 13, that is, the measuring rod 6 can slide up and down along the vertical axis of the vertical support 13.
[0036] The vertical moving device is fixedly mounted on the support plate 2. The drive end of the vertical moving device is connected to the measuring rod 6, which drives the measuring rod 6 to move along the vertical axis of the vertical moving device, that is, to move up and down perpendicular to the water surface. The current meter 12 and the water depth measuring device are both electrically connected to the input end of the controller.
[0037] In use, the river cross-section is divided into uniform sections based on the width of the river section to be measured, for example, the width of the section to be measured is designed to be 50cm. Then, water level measuring points are designed, for example, the flow velocity is measured once at a water level of 20cm for each section to be measured. Then, the monitoring device is moved sequentially above each section to be measured by the lateral moving device 20, and then the measuring rod 6 is moved towards the water surface to the designated water level to be measured.
[0038] The flow velocity information at the water point to be measured is measured by the current meter 12 and transmitted to the controller. The water depth information at the river cross section to be measured is measured by the water depth measuring device and transmitted to the controller. After repeating the above steps and measuring all the cross sections to be measured, the controller outputs the river flow information.
[0039] Example 2: As shown in the attached document Figure 1 and attached Figure 2 As shown, based on Embodiment 1, this embodiment provides a monitoring device for water flow monitoring. The support plate 2 has four movable wheels 14 at the four corners of its bottom surface, and the top surface of the transverse bracket 1 has two first sliding grooves 15 that cooperate with the movable wheels 14. The movable wheels 14 slide in the first sliding grooves 15.
[0040] Specifically, the support plate 2 has a square structure, and its width matches the width of the transverse support 1. Preferably, the first groove 15 can be formed using the grooves of the U-shaped steel on both sides of the top surface of the transverse support 1.
[0041] The lateral movement device 20 includes a first motor 3, on the output shaft of the first motor 3 is a first gear 4, the first gear 4 meshes with a first rack 5 arranged axially upward along the lateral support 1, and drives the support plate 2 to slide axially along the lateral support 1; the first motor 3 is a stepper motor, and the first motor 3 is electrically connected to the controller.
[0042] Specifically, the first rack 5 is fixedly mounted on the outer surface of the U-shaped steel on one side of the top surface of the transverse support 1. The controller is electrically connected to the first motor 3 and is used to automatically control the step distance and frequency of the first motor 3. The first motor 3 is designed as a stepper motor to facilitate control of the step distance.
[0043] When in use, the first motor 3 is started and the rotation of the output shaft of the first motor 3 drives the first gear 4 to rotate. Because the first rack 5 is meshed with the first gear, the rotation of the first gear 4 drives the moving wheel 14 of the support plate 2 to move back and forth along the corresponding first slide groove 15. The lateral movement of the support plate 2 simultaneously drives the vertical support 13 and the vertical moving device to move synchronously.
[0044] A second slide groove 16 is vertically provided on the vertical support 13. A slider 17 is provided in the second slide groove 16. The slider 17 is connected to the measuring rod 6 and slides up and down in the second slide groove 16.
[0045] The vertical moving device includes a second motor 7, on the output shaft of which a second gear 8 is mounted. The second gear 8 meshes with a second rack 9 arranged axially upward along the measuring rod 6, driving the measuring rod 6 to move in a direction perpendicular to the water surface. The second motor 7 is a stepper motor and is electrically connected to the controller.
[0046] The second rack 9 is mounted on the flat steel surface of the measuring rod 6. The controller is used to automatically control the step distance and frequency of the second motor 7. The second motor 7 is designed as a stepper motor for easy control of the step distance.
[0047] When in use, the second motor 7 is started and the rotation of the output shaft of the second motor 7 drives the second gear 8 to rotate. Because the second gear 9 is meshed with a fixed second rack, the rotation of the second gear 8 drives the slider 17 to move up and down along the corresponding second slide groove 16, thereby realizing the vertical movement of the measuring rod 6 perpendicular to the water surface.
[0048] The water depth measuring device includes a pulley encoder 10 mounted on the output shaft of the second motor 7 on the vertical moving device and a gravity sensor 11 mounted on the lower end of the measuring rod 6. Both the pulley encoder 10 and the gravity sensor 11 are electrically connected to the controller.
[0049] Specifically, the gravity sensor 11 is fixed to the lower end of the measuring rod 6 by a traction rope. The pulley encoder 10 is mounted on the output shaft of the second motor 7 on the vertical moving device and rotates synchronously with the second motor 7. Both the pulley encoder 10 and the gravity sensor 11 are electrically connected to the input terminal of the controller.
[0050] When the measuring rod 6 is lowered and the gravity sensor 11 is placed in the water, and the gravity reading changes significantly, the reading of the pulley encoder 10 at that moment is recorded. Then, when the measuring rod 6 is lowered to the riverbed and the gravity reading changes significantly for the second time, the reading of the pulley encoder 10 is recorded again. The depth information of the current river cross-section is obtained by using the two readings of the pulley encoder 10. As the measuring rod 6 is lowered to different set water levels, the river flow velocity information is recorded.
[0051] Example 3: As shown in the attached document Figure 1 and attached Figure 2 As shown in Example 2, this example provides a monitoring device for water flow monitoring, which also includes a display device connected to the controller for displaying flow velocity, water depth and flow rate information.
[0052] The display device is connected to the output of the controller to display the acquired water flow velocity, water depth, and flow rate information. In addition, the controller is also equipped with a wireless network communication module, which is used to upload the acquired flow velocity, water depth, and flow rate information to the remote cloud control terminal, and also to receive the step distance and frequency information of horizontal and vertical movement sent by the cloud control terminal.
[0053] This utility model also includes a photovoltaic power generation module, which is disposed on the outer side of one end of the horizontal support 1. The photovoltaic power generation module mainly includes a photovoltaic panel, a storage battery, and an inverter. The photovoltaic panel is fixedly installed on the horizontal support 1 by a photovoltaic panel bracket, and converts light energy into electrical energy and stores it in the storage battery during operation. In use, the storage battery is connected to the inverter, and the output terminal of the inverter is electrically connected to the power input of the first motor 3 and the second motor 7, respectively, converting the electrical energy into the required voltage to provide power to the first motor 3 and the second motor 7.
[0054] The output of the photovoltaic power generation module is connected to the inverter, and the output of the inverter is connected to the power input of the first motor 3 and the second motor 7, respectively, to provide them with power. At the same time, the output of the photovoltaic power generation module is also connected to the power input of the controller to provide it with power.
