Description

Technical Field

[0001] The present application relates to the field of flow rate monitoring devices, and in particular to a river flow rate monitoring device. Background Art

[0002] Flow rate monitoring devices are instruments designed for measuring flow rate in industries such as hydrological monitoring, river flow monitoring, agricultural irrigation, municipal water supply and drainage, and industrial wastewater. Radar flowmeters are commonly used for non-contact measurement of surface flow velocity in water bodies. They utilize radar technology to determine flow rate by measuring the interaction between an object and radar waves.

[0003] A flow rate monitoring device typically consists of a vertical pole with a crossbar mounted on its upper end. This crossbar supports the monitor above the river, where it monitors the flow rate. To facilitate adjustment of the monitor's position and angle, some crossbars slide vertically along the pole, allowing operators to easily adjust or inspect the monitor.

[0004] Regarding the above-mentioned related technologies, after lowering the height of the monitor, it is still difficult for maintenance personnel to repair the monitor because the monitor is far away from the shore. Utility Model Content

[0005] In order to make it more convenient for maintenance personnel to repair the monitoring instrument, the present application provides a river flow rate monitoring device.

[0006] The present application provides a river flow rate monitoring device that adopts the following technical solutions:

[0007] A river flow rate monitoring device includes a vertically arranged pole, a sleeve is provided on the outer surface of the pole, a cross bar is connected to the outside of the sleeve, and a monitoring instrument is provided on the cross bar; the sleeve is provided with a first drive assembly, the first drive assembly drives the sleeve to rise and fall along the pole and rotate at the same time, the sleeve drives the cross bar to rotate, so that the monitoring instrument moves toward the shore.

[0008] By adopting the above technical solution, a sleeve that can be raised and lowered and rotated along the vertical pole is set. The rotating sleeve drives the horizontal bar and the monitor connected to it to rotate, so that the monitor moves closer to the shore and descends, which enables maintenance personnel to flexibly adjust the monitor and facilitates maintenance.

[0009] Optionally, a slider is provided on the outer surface of the vertical pole, and the slider is divided into a vertical section and a spiral section. The vertical section is located at the upper end of the spiral section. A sliding groove is provided inside the sleeve, and the spiral section cooperates with the sliding groove to enable the sleeve to rotate while rising and falling.

[0010] By adopting the above technical solution, the setting of the vertical section can realize the adjustment of the height of the monitor so that the monitor can reach a better detection state. The design of the spiral section enables the sleeve to rotate while being raised and lowered, which is convenient for maintenance personnel to inspect the monitor. The design of setting a slider instead of a slide on the vertical pole reduces the possibility of the slide getting stuck in gravel and foreign objects, and improves the reliability of the sleeve sliding.

[0011] Optionally, the first drive assembly includes a first drive member, the first drive member is connected to a first winding wheel, the first winding wheel winds up a first pull rope, the first pull rope is connected to a fixed sleeve and connected to the upper end of the fixed sleeve, and the fixed sleeve is coaxially rotatably connected to the upper end of the sleeve.

[0012] By adopting the above technical solution, the operation of the first drive component can conveniently control the lifting and lowering of the fixed sleeve. The fixed sleeve is lifted and lowered under the tension of the first pull rope and the gravity of the cross bar. At the same time, the sleeve rotates under the action of the slider and the slide groove to complete the movement process of the monitor.

[0013] Optionally, the cross bar includes a first cross section, a second cross section and a third cross section, the first cross section can be mounted outside the second cross section, the second cross section can be mounted outside the third cross section, the monitor is arranged at one end of the third cross section away from the vertical pole, and the first cross section, the second cross section and the third cross section jointly realize the extension and retraction of the cross bar.

[0014] By adopting the above technical solution, the retractable crossbar design not only increases the adjustment range of the monitor, but also shortens the length of the crossbar, reduces the possibility of the crossbar being obstructed by obstacles near the vertical pole during the rotation and descent, and reduces the space required for rotation.

[0015] Optionally, the second transverse section is provided with a first spring, which is fixedly connected to the first transverse section and applies force to the second transverse section away from the vertical pole; the third transverse section is provided with a second spring, which is fixedly connected to the second transverse section and applies force to the third transverse section away from the vertical pole.

[0016] By adopting the above technical solution, the setting of the spring enables the cross bar to automatically extend when no external force is applied, and the cross bar length is the longest. When the cross bar needs to be shortened, external force is applied to the cross bar to compress the spring to adjust the length of the cross bar.

[0017] Optionally, the elastic force of the first spring is smaller than the elastic force of the second spring.

[0018] By adopting the above technical solution, when the third horizontal section is subjected to external force, the first spring is compressed before the second spring, and the position closer to the vertical pole is contracted first, so that the center of gravity of the entire horizontal bar is closer to the vertical pole, thereby improving the stability of the horizontal bar when it is contracted.

[0019] Optionally, the third transverse section is provided with a second drive assembly, the second drive assembly includes a second drive member, the second drive member is connected to a second winding wheel, the second winding wheel winds up a second pull rope, and the second pull rope is connected to the third transverse section.

[0020] By adopting the above technical solution, the second drive component provides external force for the contraction of the cross bar by winding the second pull rope. The maintenance personnel can control the cross bar by controlling the second drive component, making the position adjustment of the monitor more precise and convenient.

[0021] Optionally, the monitor is provided with a mounting bracket, the mounting bracket is hinged to the monitor and fixed by bolts, and the mounting bracket is rotatably connected to the cross bar and fixed by bolts.

[0022] By adopting the above technical solution, the flexible connection between the monitor's mounting frame, the crossbar and the monitor itself allows the angle and position of the monitor to be adjusted at will, and is fixed by bolts, which is both flexible and stable, ensuring the accuracy and reliability of monitoring.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By installing a lifting and rotating sleeve on the outer surface of the pole, the monitor can be flexibly adjusted, allowing it to move closer to the shore, making it easier for maintenance personnel to operate;

[0025] 2. The coordinated design of the slider and the slide groove enables the sleeve to rotate while being raised and lowered, thus improving the flexibility and diversity of the position adjustment of the monitor;

[0026] 3. The flexible connection between the monitor's mounting frame, crossbar and the monitor itself allows the angle and position of the monitor to be adjusted at will, and is fixed by bolts, which is both flexible and stable, ensuring the accuracy and reliability of monitoring.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0035] The present application embodiment discloses a river flow rate monitoring device. Figure 1 and Figure 2A river flow rate monitoring device includes a vertically arranged upright pole 1, the bottom end of the upright pole 1 is fixed to the bank of the river, a sleeve 2 is provided on the outer surface of the upright pole 1, a crossbar 3 is fixed to the outside of the sleeve 2, the crossbar 3 is perpendicular to the upright pole 1, and a monitor 6 for monitoring the river flow rate is provided at the end of the crossbar 3 away from the upright pole 1. The sleeve 2 is connected to a first drive assembly 4, which can drive the sleeve 2 to rise and fall along the upright pole 1 and rotate at the same time. The sleeve 2 drives the crossbar 3 to rise and fall and rotate at the same time, so that the monitor 6 at the end of the crossbar 3 moves closer to the bank, allowing maintenance personnel to inspect and adjust the monitor 6 on the bank without any auxiliary tools, solving the problem that the monitor 6 is far away from the bank and difficult for maintenance personnel to operate.

[0036] Specifically, refer to Figure 1 A slider 11 is fixed to the outer surface of the vertical pole 1. The slider 11 consists of a vertical section 111 and a spiral section 112. The vertical section 111 is located above the spiral section 112. The slider 11 of the vertical section 111 is divided into a wide section and a narrow section based on the width of the slider 11, with the wide section located above the narrow section. A chute 22 is provided within the sleeve 2. The width of the chute 22 matches the width of the wide section, and the length of the narrow section is no less than the height of the sleeve 2. As the sleeve 2 slides up and down along the vertical pole 1, the chute 22 engages with the wide section. In the vertical section 111, the sleeve 2 only moves up and down without rotating, allowing staff to adjust the height of the monitor 6. In the spiral section 112, the sleeve 2 simultaneously rotates while moving up and down. This allows the monitor 6 to be rotated to the shore, making it easier for maintenance personnel to inspect the monitor 6. Furthermore, the design of the slider 11 on the vertical pole 1 instead of the chute 22 reduces the possibility of debris or foreign objects becoming stuck in the chute 22, thereby improving the sliding reliability of the sleeve 2.

[0037] Reference Figure 2 The first drive assembly 4 includes a first drive member 41, which is fixed to the bottom of the upright 1. The first drive member 41 is connected to a first reel 42, on which a first pull rope 43 is wound. The first pull rope 43 extends upward from the interior of the upright and exits near the top of the upright 1. It is connected to a fixed sleeve 21 and is connected to the upper end of the fixed sleeve 21. The fixed sleeve 21 is coaxially connected to the upper end of the sleeve 2 via a T-shaped slot and a T-shaped block. When the first drive member 41 drives the first reel 42 to reel or release the first pull rope 43, the fixed sleeve 21 drives the sleeve 2 to rise, fall, and rotate along the upright 1.

[0038] Further, refer to Figure 4 The crossbar 3 is designed as a telescopic structure to increase the adjustment range of the monitor 6 and reduce the possibility of being obstructed by obstacles near the vertical pole 1 during the rotation and descent process.

[0039] Specifically, refer to Figure 4The crossbar 3 includes a first cross section 31, a second cross section 32, and a third cross section 33. The first cross section 31 can be mounted on the outside of the second cross section 32, and the second cross section 32 can be mounted on the outside of the third cross section 33. The monitor 6 is located at the end of the third cross section 33 away from the upright 1. This mounting design allows the crossbar 3 to extend and retract. Furthermore, a first spring 34 is fixed to the end of the second cross section 32 near the upright 1. One end of the first spring 34 is fixed to the first cross section 31, and the other end is fixed to the second cross section 32. The first spring 34 applies a force to the second cross section 32 away from the upright 1. The third cross section 33 is fixed to a second spring 35. One end of the second spring 35 is fixed to the second cross section 32, and the other end is fixed to the third cross section 33. The second spring 35 applies a force to the third cross section 33 away from the upright 1. In the absence of external forces, the elastic forces of the first and second springs 34 and 35 keep the crossbar 3 in an extended position.

[0040] In addition, the elastic force of the first spring 34 is designed to be smaller than the elastic force of the second spring 35. Thus, when the crossbar 3 needs to be retracted, the third cross section 33 is subjected to an external force and will first compress the first spring 34, causing the position closer to the upright 1 to retract first, thereby ensuring the stability of the crossbar 3 during the retraction process.

[0041] Reference Figure 4 The first and second transverse sections 31 and 32 are both fixedly connected to the inner portions of the limit blocks 36. When the second and third transverse sections 32 and 33 abut against the limit blocks 36, the second and third transverse sections 32 and 33 are retracted into position. If the elastic forces of the first and second springs 34 and 35 are different, the second transverse section 32 will retract into position first, followed by the third transverse section 33.

[0042] Reference Figure 3 A second drive assembly 5 is provided at a position near the vertical rod 1 on the horizontal rod 3. The second drive assembly 5 includes a second drive member 51 connected to a second reel 52. A second pull rope 53 is wound on the second reel 52, and the second pull rope 53 is connected to the third horizontal section 33. When the horizontal rod 3 needs to be retracted, the second drive member 51 drives the second reel 52 to reel in the second pull rope 53. The end of the second pull rope 53 is fixedly connected to the third horizontal section 33. The second drive assembly 5 provides an external force for retracting the horizontal rod 3.

[0043] In addition, refer to Figure 1 Monitor 6 is equipped with a mounting bracket 61, which connects monitor 6 to crossbar 3. Mounting bracket 61 is hingedly connected to the housing of monitor 6 and secured by bolts. Mounting bracket 61 is also pivotally connected to third cross section 33 and secured by bolts. This connection allows for flexible and stable adjustment of the angle and orientation of monitor 6, ensuring accurate and reliable monitoring.

[0044] Further, refer to Figure 1 A support rod 7 is fixedly connected to the position of the first horizontal section 31 near the vertical rod 1. One end of the support rod 7 is connected to the cross bar 3, and the other end is fixed to the outer wall of the sleeve 2. The support rod 7 provides a triangular and stable support for the cross bar 3, thereby improving the stability of the cross bar 3.

[0045] In this embodiment, both the first drive member 41 and the second drive member 51 are drive motors. Waterproof covers (not shown) are installed on the vertical rod 1 at the position corresponding to the first drive member 41 and on the horizontal rod 3 at the position corresponding to the second drive member 51. These covers provide both dust and water resistance and prevent accidental contact.

[0046] The implementation principle of a river flow rate monitoring device according to an embodiment of the present application is as follows: through the use of a liftable and rotatable sleeve 2, a retractable crossbar 3, and a flexibly adjustable monitor 6 mounting bracket 61, the position of the monitor 6 can be flexibly adjusted, facilitating operation by maintenance personnel while ensuring the accuracy and reliability of monitoring. When the monitor 6 needs to be repaired, the first drive member 41 is activated, extending the first pull rope 43. The crossbar 3 descends under its own weight, causing the sleeve 2 to descend and rotate along the vertical pole 1. The rotating sleeve 2 drives the connected crossbar 3 and monitor 6 to rotate, causing the monitor 6 to approach the shore and descend. This allows maintenance personnel to flexibly adjust the monitor 6 and facilitates maintenance.

[0047] The embodiments of the present application have the effect of making the maintenance of the monitoring instrument more convenient.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
