Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring equipment technology, and in particular to a video flow rate monitoring device. Background Technology

[0002] Current methods for measuring the flow of rivers, canals, and channels include ultrasonic, electromagnetic, and Venturi flow measurement techniques. However, these methods are greatly affected by the quality of the river water and the river channel itself. Furthermore, existing flow velocity monitoring equipment first acquires images of the river and then calculates the river velocity using a neural network-based computational model. These existing flow velocity monitoring devices are susceptible to external factors and have complex technical issues during the flow velocity measurement process.

[0003] According to the existing patent document CN216117672U, a flow velocity monitoring device based on video acquisition includes a processor, a rope retraction and release device, a rope, a counterweight, a scale plate, and a video acquisition device. The first end of the rope is connected to the rope retraction and release device, and the second end is connected to the counterweight. The scale plate is positioned at a predetermined height below the rope retraction and release device, and when the rope is released, the position of the scale plate corresponds to the position of the rope. In use, the video acquisition device captures images of the rope and the scale plate as monitoring images, indirectly calculating the flow rate and intuitively reflecting the river's flow velocity. This reduces complexity by eliminating the need for complex neural network-based algorithms. However, while this solution achieves flow velocity monitoring, it cannot observe the water's transparency, thus failing to determine the degree of water pollution, resulting in inconvenience during use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A video flow rate monitoring device includes a fixed box, with a water inlet pipe fixedly installed at one end and a drain pipe fixedly installed at the other end away from the water inlet pipe.

[0007] In some specific embodiments, a movable column is installed on the displacement mechanism, and an observation component is fixed to one end of the movable column. The observation component is movably installed inside the fixed box.

The speed measuring mechanism includes a rotating disk, which is mounted on the fixed plate by a speed sensor. The rotating disk is located on the side of the fixed box near the water inlet pipe.

[0011] In some specific embodiments, an arc-shaped plate is welded onto the rotating disk. The arc-shaped plate rotates with the rotating disk and is pushed by the water flow when the water flows through the fixed box, thereby measuring the water flow speed through a speed sensor.

[0027] In this embodiment, the fixed box (1): as the main structure of the entire device, the fixed box (1) plays a key role in supporting and accommodating other components. It ensures that the various components of the device can be stably installed in the appropriate position, providing basic support for other components.

[0028] The fixed box 1) forms a relatively enclosed space, which allows the water to flow stably in it, providing a stable environment for subsequent flow velocity monitoring and water quality observation.

[0029] Inlet pipe 3) and drain pipe 2):

[0030] The inlet pipe 3) is fixedly installed at one end of the fixed box 1) to introduce the water to be monitored into the fixed box 1. Its function is to ensure that the water can smoothly enter the device so as to carry out subsequent monitoring operations.

[0031] Drain pipe 2 is fixedly installed at the other end of the fixed box 1, opposite to the inlet pipe 3, and is used to drain the water inside the fixed box 1. This design allows the water to circulate inside the device, facilitating multiple monitoring sessions.

[0032] Control valves 4 are fixedly installed on both the inlet pipe 3 and the outlet pipe 2. The function of the control valves 4 is to control the inflow and outflow of water, so that the water flow can remain still inside the fixed box 1 when needed, thereby facilitating operations such as flow rate monitoring and water quality observation.

[0033] Sealing tube 8 and video acquisition mechanism 9:

[0034] The sealing tube 8 is fixedly installed on the side of the fixed box 1, providing protection and installation space for the video acquisition mechanism 9. The design of the sealing tube 8 ensures the stable installation of the video acquisition mechanism 9 inside the device, while preventing water from damaging the video acquisition mechanism 9.

[0035] The video acquisition mechanism 9 is installed inside the sealed tube 8 to acquire video images inside the fixed tank 1. The video acquisition mechanism 9 can record the flow of water inside the fixed tank 1 in real time, providing intuitive data support for subsequent flow rate monitoring and water quality analysis.

[0037] The slot 5 is formed on the top of the fixed box 1, and an observation window and scale line 6 are fixedly installed inside. The design of the slot 5 provides sliding space for the protrusion 18, allowing the observation component 10 to move inside the fixed box 1.

[0038] The observation window is located on one side of the slot 5, allowing staff to directly observe the water quality inside the fixed tank 1 and the position of the observation component 10. Through the observation window, staff can monitor the water flow and water transparency in real time.

[0039] The scale line 6 is set along the length of the slot 5 to assist in measuring and judging the positional changes of the observation component 10. The scale line 6 can provide accurate measurement data, enabling staff to accurately analyze the displacement of the observation component 10 and correlate it with parameters such as flow velocity monitoring.

[0040] Displacement mechanism 7:

[0041] The displacement mechanism 7 is fixedly installed on the side of the fixed box 1 away from the sealing tube 8, and is used to drive the movable column 16, thereby moving the observation component 10 inside the fixed box 1.

[0044] In some specific embodiments, the observation assembly 10 includes an observation plate 17, the top of which is fixed with a protrusion 18. The protrusion 18 is movably installed inside the slot 5 and slides with the inner wall of the slot 5.

[0045] In some specific embodiments, an opening is provided between the fixed box 1 and the sealing tube 8, and a glass plate 13 is sealed and fixed inside the opening. The video acquisition mechanism 9 is installed inside the sealing tube 8 and cooperates with the glass plate 13 to acquire video images inside the fixed box 1.

[0046] In this embodiment, it should be noted that the displacement mechanism 7 is connected to the movable column 16: the displacement mechanism 7 is installed on the outside of the fixed box 1, and its output end is fixedly connected to one end of the movable column 16. This fixed connection method enables the displacement mechanism 7 to precisely drive the movable column 16 to perform linear motion.

[0047] Connection between movable column 16 and observation component 10: The end of movable column 16 away from displacement mechanism 7 passes through the side wall of fixed box 1 and is fixedly connected to observation component 10. Movable column 16 and side wall of fixed box 1 adopt a sliding fit to ensure that movable column 16 can move freely within side wall of fixed box 1 while maintaining good sealing to prevent water leakage.

[0048] Composition and Installation of Observation Component 10: Observation component 10 consists of an observation plate 17 and a protrusion 18. The observation plate 17 is located inside the fixed box 1 and is used to block water flow or serve as a reference to assist in observing the transparency of the water. The protrusion 18 is fixedly installed on the top of the observation plate 17 and extends into the interior of the slot 5. The protrusion 18 slides against the inner wall of the slot 5. This sliding fit allows the observation component 10 to move smoothly along the direction of the slot 5 inside the fixed box 1, while ensuring the stability and guidance of the observation component 10 during movement.

[0049] Connection between the fixed box 1 and the sealing tube 8: An opening is provided between the fixed box 1 and the sealing tube 8, which allows the internal space of the fixed box 1 to communicate with the internal space of the sealing tube 8.

[0050] The glass plate 13 is sealed and fixed inside the opening. The installation of the glass plate 13 not only ensures the airtightness between the fixed box 1 and the sealing tube 8, but also provides a transparent observation window for the video acquisition mechanism 9.

[0051] Installation and function of video acquisition mechanism 9: The video acquisition mechanism 9 is fixedly installed on the inner wall of the sealed pipe 8 and cooperates with the glass plate 13. The video acquisition mechanism 9 acquires video images inside the fixed box 1 through the glass plate 13, including the flow status of water, the operation of the velocity measuring mechanism 12, and the transparency of water quality, providing intuitive data support for subsequent flow velocity monitoring and water quality analysis.

[0052] In some specific embodiments, a fixing plate 11 is welded inside the fixing box 1, and a speed measuring mechanism 12 is rotatably mounted on the fixing plate 11. The speed measuring mechanism 12 includes a rotating disk 14, which is mounted on the fixing plate 11 by a speed sensor. The rotating disk 14 is located on the side of the fixing box 1 near the water inlet pipe 3.

[0053] In this embodiment, it should be noted that:

[0054] Installation of fixing plate 11: Fixing plate 11 is welded inside the fixing box 1, and fixing plate 11 provides a stable mounting base for speed measuring mechanism 12.

[0055] Composition and installation of speed measuring mechanism 12: Speed ​​measuring mechanism 12 mainly includes a rotating disk 14 and an arc plate 15. The rotating disk 14 is mounted on the fixed plate 11 via a speed sensor, located on the side of the fixed box 1 near the water inlet pipe 3. The arc plate 15 is welded to the rotating disk 14. When water flows through the fixed box 1, the water flow impacts the arc plate 15, causing the rotating disk 14 to rotate around its axis.

[0056] Speed ​​measurement principle: The speed sensor monitors the rotational speed of the rotating disk 14 in real time and converts the speed signal into an electrical signal output. Based on the pre-calibrated relationship between the rotational speed and the water flow velocity, the actual water flow velocity can be calculated, thus achieving direct measurement of the water flow velocity.

[0057] In some specific embodiments, an arc-shaped plate 15 is welded onto the rotating disk 14. The arc-shaped plate 15 rotates with the rotating disk 14 and is pushed by the water flow when the water flows through the fixed box 1, thereby measuring the water flow speed through the speed sensor.

[0058] In some specific embodiments, the water inlet pipe 3 and the drain pipe 2 are located at opposite ends of the fixed box 1, and both the water inlet pipe 3 and the drain pipe 2 are connected to the interior of the fixed box 1.

[0059] In some specific embodiments, the sealing tube 8 is connected to the interior of the fixed box 1, and the video acquisition mechanism 9 is fixedly installed on the inner wall of the sealing tube 8.

[0060] The layout of the inlet pipe 3 and the outlet pipe 2: The inlet pipe 3 and the outlet pipe 2 are located at opposite ends of the fixed box 1, and both are connected to the interior of the fixed box 1. This layout allows water to smoothly enter and exit the fixed box 1, forming a complete water circulation path.

[0061] The sealing tube 8 is connected to the interior of the fixed box 1, and the video acquisition mechanism 9 is fixedly installed on the inner wall of the sealing tube 8. This connection ensures that the video acquisition mechanism 9 can effectively acquire video images inside the fixed box 1, while also providing good protection for the video acquisition mechanism 9.

[0062] In some specific embodiments, one end of the movable column 16 is fixedly connected to the output end of the displacement mechanism 7, and the other end away from the displacement mechanism 7 passes through the side wall of the fixed box 1 and is fixedly connected to the observation component 10. The movable column 16 slides with the side wall of the fixed box 1.

[0063] In some specific embodiments, the length direction of the top slot 5 of the fixed box 1 is consistent with the length direction of the fixed box 1, the scale line 6 is set along the length direction of the slot 5, and the observation window is located on one side of the slot 5 for observing the water quality inside the fixed box 1 and the position of the observation component 10.

[0064] The slot 5 is designed such that the top of the fixed box 1 has a slot 5, and the length direction of the slot 5 is consistent with the length direction of the fixed box 1. This design provides sliding space for the protrusion 18, allowing the observation component 10 to move inside the fixed box 1 along the direction of the slot 5.

[0065] Installation of scale line 6 and observation window: Scale line 6 is set inside the slot 5 along the length of the slot 5, and is used to accurately measure the displacement distance of the observation component 10. The observation window is located on one side of the slot 5. Through the observation window, the staff can directly observe the water quality inside the fixed box 1, including the state of water flow, color, transparency, etc., as well as the positional changes of the observation component 10.

[0066] The working method of this utility model:

[0067] First, fix the inlet pipe 3 and the drain pipe 2 to one end and the other end of the fixed box 1 respectively, and then fix the control valve 4 on them.

[0068] Then, the sealing tube 8 is fixedly installed on the side of the fixed box 1, and the video acquisition mechanism 9 is installed inside the sealing tube 8. At the same time, the glass plate 13 is sealed and fixed in the opening between the fixed box 1 and the sealing tube 8 so that the video acquisition mechanism 9 and the glass plate 13 fit well.

[0069] Next, a slot 5 is made on the top of the fixed box 1, and an observation window and scale line 6 are fixedly installed inside the slot 5.

[0070] Then, the displacement mechanism 7 is fixedly installed on the side of the fixed box 1 away from the sealing tube 8, and the movable column 16 is installed on the displacement mechanism 7. At the same time, the observation component 10 is installed on one end of the movable column 16, and the protrusion 18 of the observation component 10 is ensured to slide and cooperate with the inner wall in the slot 5.

[0071] Finally, the fixing plate 11 is welded inside the fixing box 1, and the rotating disk 14 of the speed measuring mechanism 12 is installed on the fixing plate 11 through the speed sensor. At the same time, the arc plate 15 is welded on the rotating disk 14 to complete the assembly of the entire device.

[0072] Flow velocity monitoring implementation:

[0073] When flow rate monitoring is required, first open the control valve 4 on the inlet pipe 3 to allow water to flow into the fixed box 1 through the inlet pipe 3. After the water flows into the fixed box 1, it impacts the arc-shaped plate 15 in the speed measuring mechanism 12, causing the rotating disk 14 to rotate. The speed sensor measures the rotation speed of the rotating disk 14 in real time. Based on the pre-calibrated relationship between the rotation speed and the water flow velocity, the current water flow velocity can be calculated.

[0074] Meanwhile, the video acquisition mechanism 9 will collect video images of the water flow inside the fixed box 1 and the speed measuring mechanism 12. By analyzing the rotation of the rotating disk 14 in the video, information on the water flow speed can also be indirectly obtained, further improving the accuracy and reliability of flow velocity monitoring.

[0075] Water transparency monitoring implementation:

[0076] After the water flows into the fixed box 1, the control valves 4 on the inlet pipe 3 and the outlet pipe 2 are closed to make the water flow stop inside the fixed box 1.

[0077] At this time, the movable column 16 is adjusted by the displacement mechanism 7, which drives the observation component 10 to move inside the fixed box 1, changing the distance between the observation plates 17.

[0078] The water quality inside the fixed tank 1 is observed through the observation window. Simultaneously, images acquired by the video acquisition mechanism 9 are used to assess the water transparency based on changes in the distance between the observation plates 17 and the propagation of light in the water, thus revealing the extent of water pollution. The scale line 6 can be used to precisely measure the displacement of the observation plates 17, allowing for a more accurate analysis of the relationship between water transparency and displacement, enabling quantitative or semi-quantitative assessment of water transparency.

[0079] Data recording and analysis:

[0080] During flow velocity monitoring and water transparency observation, the rotation speed data measured by the rotation speed sensor and the video images collected by the video acquisition mechanism 9 can be transmitted to external data processing equipment such as computers and controllers.

[0081] Specialized data processing software is used to record, organize, and analyze this data, generating charts such as flow velocity-time curves and water transparency change curves. This allows for a more intuitive display and study of changes in water flow velocity and water quality, providing a scientific basis for water quality monitoring and management of rivers, canals, and other waterways.

[0082] Example

[0083] Device Installation: Install the inlet pipe 3 and outlet pipe 2 at both ends of the fixed box 1, and install the control valve 4. The sealing pipe 8 is installed on the side of the fixed box 1, and the video acquisition mechanism 9 is installed inside. The glass plate 13 seals the opening between the fixed box 1 and the sealing pipe 8. The top slot 5 contains an observation window and scale lines 6. The displacement mechanism 7 is fixed to the other side of the fixed box 1. The movable column 16 connects the displacement mechanism 7 and the observation component 10. The protrusion 18 of the observation component 10 slides against the inner wall of the slot 5. The fixing plate 11 is welded inside the fixed box 1, and the speed measuring mechanism 12 is installed.

[0084] Flow velocity monitoring: When the inlet pipe 3 and control valve 4 are opened, water flows into the fixed box 1, impacting the arc-shaped plate 15 and causing the rotating disk 14 to rotate. The speed sensor measures the rotation speed and calculates the flow velocity. At the same time, the video acquisition mechanism 9 acquires images and analyzes the rotation of the rotating disk 14 to indirectly measure the flow velocity.

[0085] Water transparency observation: After water is introduced, control valve 4 is closed to stop the water flow. The position of observation component 10 is adjusted using displacement mechanism 7, and the spacing of observation plates 17 is changed. Water transparency is observed using the observation window and video acquisition mechanism 9. Displacement is measured on scale line 6. The relationship between displacement and transparency is analyzed to assess water pollution.

[0086] Data processing: The speed sensor data and video acquisition mechanism 9 images are transmitted to external devices, recorded and analyzed by software, and curves are generated to provide a scientific basis for water quality monitoring and management.

[0087] By adopting the above-disclosed technical solution of this utility model, the following beneficial effects are obtained:

[0088] I. Precise Flow Velocity Measurement

[0089] This device achieves precise measurement of water flow velocity through the speed measuring mechanism 12. The water flow drives the arc-shaped plate 15, which in turn rotates the rotating disk 14. A speed sensor monitors the rotational speed of the disk 14 in real time, accurately converting the speed signal into water flow velocity data. This direct measurement method reduces errors caused by complex water flow conditions and improves the accuracy of flow velocity measurement. Simultaneously, the video acquisition mechanism 9 visually records the rotation of the disk 14, providing dual assurance for flow velocity measurement and further enhancing the reliability of the measurement results.

[0090] II. Visual observation of water transparency

[0091] The device not only measures water flow velocity but also provides intuitive and adjustable observation of water transparency through the observation component 10 and displacement mechanism 7. By changing the distance between the observation plates 17, the observation angle and range can be flexibly adjusted, thereby more accurately assessing water transparency. This adjustable observation function allows the device to adapt to the water quality monitoring needs of different pollution levels, facilitating a rapid understanding of water pollution conditions.

[0092] III. Multi-dimensional data support

[0093] During the monitoring process, the video acquisition unit 9 records in real time the flow status of the water inside the fixed tank 1, the operation of the speed measuring mechanism 12, and changes in water transparency. This video data, combined with the numerical data from the speed sensor, provides a rich source of information for subsequent data analysis. By comprehensively analyzing this data, a more complete understanding of the characteristics of the water flow and the trends in water quality changes can be achieved, providing a scientific basis for water quality monitoring and management.

[0094] IV. Convenient Operation and Maintenance

[0095] The device has a reasonable overall structural design, with clear connections between various components, facilitating installation, commissioning, and maintenance. The control valve 4 allows for easy control of water flow inlet and outlet, ensuring smooth monitoring. Furthermore, cleaning and maintenance of the device are relatively simple; only periodic cleaning of components such as the fixed box 1, inlet pipe 3, and drain pipe 2, along with inspection and maintenance of critical components, are required, reducing maintenance costs and workload.

[0096] V. Broad Application Prospects

[0097] This device solves the problems of existing flow velocity monitoring equipment being greatly affected by external factors, being highly complex, and being unable to measure water transparency. It has the advantages of simple operation, accurate measurement, and multiple functions. It can be widely used in the flow monitoring of water bodies such as rivers, canals, and channels, as well as in water pollution assessment, providing strong technical support for water resource protection, water environment management, and water conservancy project construction, and has significant social and environmental benefits.

[0098] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
