Description

Technical Field

[0001] This utility model relates to the field of flow velocity and flow rate measurement technology, and more specifically, to a flow velocity and flow rate analysis device. Background Technology

[0002] A flow velocity and flow rate analyzer is a device used to measure and analyze the flow velocity and flow rate of fluids. It typically consists of sensors, a data acquisition system, a signal processing unit, and a display terminal. The sensors detect the flow state of the fluid and convert it into electrical signals. The data acquisition system collects these electrical signals and performs digital processing. The signal processing unit analyzes and calculates the digitized data to derive relevant parameters such as flow velocity and flow rate. Finally, these parameters are displayed intuitively to the user through the display terminal. This device is widely used in water conservancy, environmental protection, and industrial fields, providing crucial data support for water resource management, environmental monitoring, and production process control.

[0003] The LS1206B flow meter, a flow rate and velocity analysis device, mainly consists of a measuring head, a measuring rod, a pointer, and a control panel. In its structural design, both the measuring head and the pointer are adjustable in height and can be flexibly mounted on the measuring rod. Notably, the pointer is positioned above the measuring head and points in the same direction as it, primarily to provide a visual indication of the measuring head's orientation, allowing operators to more accurately determine the measurement direction. However, in practical applications, the measuring head requires not only cumbersome installation before use but also meticulous calibration afterward. Furthermore, the measuring head is subject to a certain degree of operational error during the measurement process. These factors significantly reduce the instrument's practicality in real-world use, making it difficult to meet the demands for efficient and accurate measurement. Utility Model Content

[0017] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0018] The flow rate analysis device provided in this application mainly consists of a measuring rod, a measuring head that can be raised and lowered on it, an indicating component, and a control panel. The indicating component includes an insulating component, an LED strip, a power supply, a first conductive post, and a second conductive post.

Detailed Implementation

[0027] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0028] Example

[0029] Please refer to Figures 1-6 This application provides a flow rate and flow analysis device, including: a measuring rod 3; a measuring head 2 that is liftably mounted on the measuring rod 3; an indicating component including an insulating member 14, an LED light strip 8, a power supply 13, a first conductive post 10, and a second conductive post 12. The insulating member 14 is disposed on the outer ring surface of the measuring head 2, and the LED light strip 8 is disposed on the outer side of the insulating member 14, forming an arrow-shaped indicating structure. The arrowhead and tail of the indicating structure point to the propeller and tail fin of the measuring head 2, respectively. The first conductive post 10 and the second conductive post 12 are both disposed on the outer side of the insulating member 14, and the first conductive post 10 and the second conductive post 12 are spaced apart. The positive and negative terminals of the power supply 13 are connected to the positive terminal of the LED light strip 8 and the first conductive post 10, respectively, and the second conductive post 12 is connected to the negative terminal of the LED light strip 8; and a control panel 6.

[0030] The flow rate analysis device provided in this application mainly consists of a measuring rod 3, a measuring head 2 that can be raised and lowered on it, an indicating component, and a control panel 6. The indicating component includes an insulating component 14, an LED light strip, a power supply 13, a first conductive post 10, and a second conductive post 12. The insulating component 14 is installed on the outer ring surface of the measuring head 2. The LED light strip is disposed on the outer side of the insulating component 14 and forms an arrow-shaped indicating structure, with the arrowhead and tail end pointing precisely to the propeller and tail fin of the measuring head 2, respectively. The first conductive post 10 and the second conductive post 12 are spaced apart on the outer side of the insulating component 14. The positive terminal of the power supply 13 is connected to the positive terminal of the LED light strip, the negative terminal is connected to the first conductive post 10, and the second conductive post 12 is connected to the negative terminal of the LED light strip, thereby constructing a unique circuit system. In actual water flow velocity and flow rate measurements, when the measuring head 2 is immersed in water, the conductivity of water causes the first conductive post 10 and the second conductive post 12 to conduct, closing the circuit. The power supply 13 then supplies power to the LED light strip 8, causing the LED light strip to light up and emit an arrow-shaped indicator light, allowing the operator to clearly determine the underwater direction of the measuring head 2. When the measuring head 2 is lifted out of the water, the conductive path between the first and second conductive posts is broken, the circuit cannot conduct, and the LED light strip automatically shuts off. Compared to traditional wind vanes, this device requires no additional installation, reducing installation steps and time costs. It also avoids issues such as mechanical wear affecting accuracy, providing higher directional accuracy and a more reliable basis for determining the direction of the measuring head 2, thereby effectively improving the efficiency and accuracy of flow velocity and flow rate analysis.

[0031] In a preferred embodiment, the LED light strip 8 is a color-changing light strip, and the control panel 6 is used to adjust the color change of the color-changing light strip and can switch between red light and purple light.

[0032] In some implementations, the water conditions are often complex, with turbidity being a common occurrence. Red and purple light have strong underwater penetrability, allowing them to penetrate the turbid water even in polluted environments, reducing light scattering and attenuation. This ensures that operators can clearly see the arrow-shaped indicator light emitted by the light strip, thereby accurately determining the direction of the measuring head 2.

[0033] In a preferred embodiment, the insulating element 14 is detachably mounted on the measuring head 2.

[0034] In some implementations, LED light strips may suffer damage or aging due to prolonged operation, current surges, or other unexpected factors, resulting in poor luminous performance or malfunction. In such cases, the LED light strip 8 can be replaced by removing the insulating component 14, offering the advantage of ease of operation.

[0035] In a preferred embodiment, the insulating member 14 is annular, and the power supply 13 is disposed on the insulating member 14.

[0036] The aforementioned measuring head 2 includes a detachable first measuring part 201 and a second measuring part 202. The outer ring surface of the first measuring part 201 is provided with an annular groove, and the annular groove extends to the docking point between the first measuring part 201 and the second measuring part 202. The insulating member 14 is sleeved in the annular groove.

[0037] In some embodiments, when it is necessary to disassemble the insulating component 14, the operator does not need to use complex tools or follow cumbersome steps. They only need to first disassemble the first measuring unit 201 and the second measuring unit 202 to directly remove the insulating component 14 fitted into the annular groove. The entire process is simple and easy. Furthermore, the annular design of the insulating component 14 and the built-in layout of the power supply 13 ensure that disassembly will not affect the stability of the power supply system. This convenient disassembly method greatly improves the replacement efficiency of the insulating component 14, facilitates the maintenance and repair of its internal components such as the LED light strip and the power supply 13, effectively ensures the normal operation of the flow rate analysis device, and enhances the practicality and reliability of the equipment.

[0038] Specifically, the first measuring part 201 and the second measuring part 202 are connected by a thread.

[0039] In a preferred embodiment, there are multiple LED light strips 8, which are arranged sequentially at intervals along the circumferential direction of the insulating member 14.

[0040] In some implementations, multiple LED strips 8 can illuminate simultaneously at different locations, enhancing the visibility of the indicator structure. Even in dimly lit environments with complex water flow, the arrow-shaped indicator can be clearly presented from multiple angles, ensuring that operators can easily identify the direction of water flow regardless of the viewing direction. Simultaneously, the spaced distribution avoids light interference and improves the accuracy of the indicator.

[0041] In a preferred embodiment, the outer surface of the insulating member 14 is provided with a receiving groove 11, and the first conductive post 10 and the second conductive post 12 are both disposed in the receiving groove 11.

[0042] In some embodiments, the receiving groove 11 provides good protection for the first and second conductive posts 12, effectively preventing damage to the conductive posts due to external forces such as bumps and friction during device use, thereby ensuring the stability and reliability of the circuit connection. At the same time, placing the conductive posts within the receiving groove 11 makes the overall structure of the device more compact, avoiding the risk of entanglement that might result from protruding conductive posts, reducing the probability of accidental entanglement with external objects, and facilitating operation in complex environments.

[0043] As a preferred embodiment, the bottom end of the measuring rod 3 is detachably provided with a pad 1.

[0044] In some embodiments, when measurements are taken on soft or uneven ground, the pad 1 can increase the contact area with the ground, effectively disperse the pressure of the measuring rod 3, prevent the measuring rod 3 from sinking into the ground, and make the device stand more stably.

[0045] Specifically, the pad 1 and the measuring rod 3 are detachably connected by bolts.

[0046] As a preferred embodiment, it also includes a telescopic rod 5, one end of which is provided with an annular connecting cylinder 4, and the interior of the annular connecting cylinder 4 is provided with a channel of different sizes.

[0047] The top end of the measuring rod 3 is provided with an annular connecting platform 9, and the diameter of the annular connecting platform 9 is larger than the diameter of the measuring rod 3. The top ends of the annular connecting platform 9 and the measuring rod 3 are respectively adapted to the large channel and the small channel of the annular connecting cylinder 4.

[0048] In some implementations, the measuring rod 3 is held by the telescopic rod 5, which makes it easy to operate. The telescopic rod 5 can be extended or retracted to adjust the position of the measuring head 2 relative to the operator.

[0049] Specifically, the top opening of the annular connecting cylinder 4 is threaded with a sealing plug 7.

[0050] In a preferred embodiment, the annular connecting cylinder 4 is provided with positioning bolts for positioning the measuring rod 3.

[0051] In some embodiments, the positioning bolt can be used to position the measuring rod 3, thereby improving the stability of the application during use.
