Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a detection device for simultaneously measuring the flow velocity of river water at multiple depths. Background Art

[0002] In the current extensive water conservancy, hydrology and environmental monitoring fields, the application of portable flow meters and flow meters has become indispensable. Its service scope covers from basic water conservancy and hydrological station monitoring to complex farmland irrigation systems, open channels and ditch networks, natural rivers and tunnel waterways, groundwater management in industrial and mining areas, daily monitoring by environmental protection testing agencies, in-depth research by scientific research institutions, teaching practice in educational institutions, and even professional analysis by freshwater and seawater research institutes and geological survey institutes.

[0003] However, although existing portable flow meters have shown significant advantages in many aspects, they still have limitations in their ability to detect flow velocities at multiple depths. The mainstream products on the current market are single-depth detection devices, which can only capture and analyze the water flow velocity at a specific depth, and cannot fully capture and compare the flow velocity changes at different depths at the same time point. This technical bottleneck limits the comprehensiveness and accuracy of flow velocity detection, because the velocity distribution of water flow in the vertical direction often varies with multiple factors such as water depth, riverbed morphology, water flow dynamics, and may change dynamically at any time. Therefore, the flow velocity data at a single depth is difficult to fully reflect the true condition of the water flow, especially in advanced application scenarios that require accurate assessment of water flow characteristics, hydraulic model verification, or environmental risk assessment. This deficiency is particularly obvious. Utility Model Content

In this embodiment, the detection assembly 4 includes a plurality of connection seats 42 and a plurality of flow meters 43, each connection seat 42 is detachably connected to the bottom of the previous connection seat 42 in turn, and is arranged vertically, each connection seat 42 is detachably connected to a flow meter 43, the top connection seat 42 is detachably connected to the installation assembly card, and the bottom connection seat 42 is detachably connected to the weight 5. When in use, the specific number of connection seats 42 and flow meters 43 is selected according to actual conditions, so as to achieve the effect of comprehensively capturing and comparing the flow velocity changes at different depths at the same time point; when selecting the specific number of connection seats 42 and flow meters 43, multiple connection seats 42 can be selected to achieve the effect of adjusting the distance between the two flow meters 43, so as to adapt to different situations in actual use. In this embodiment, the power source and the flow meter 43 are electrically connected to the controller 41, and the controller 41 is fixedly installed on the floating base 1 to control the normal operation of the overall device.

[0024] In this embodiment, the velocity meter 43 is an existing device, so no further details are given here.

[0025] See also Figure 2In this embodiment, a first threaded connection hole 47 is formed at one end of the connecting seat 42, and a first connecting screw 46 matching the first threaded connection hole 47 is fixedly connected to the other end. The first connecting screw 46 of one connecting seat 42 is threadedly connected to the first threaded connection hole 47 of another connecting seat 42, which is convenient for installation and disassembly. The user can choose how many connecting seats 42 and flow meters 43 to install according to the river water depth that needs to be detected, thereby providing practicality and convenience.

[0026] See also Figure 1 In this embodiment, the mounting assembly includes a mounting seat 11 and a second connecting screw. The mounting seat 11 is clamped in the mounting through hole, and the second connecting screw is fixedly connected to the bottom of the mounting seat 11. The second connecting screw is threadedly connected to the first threaded connection hole 47 of one of the connecting seats 42.

There is no need for the staff to hold the flow meter 43, thereby improving work efficiency.

[0027] See also Figure 2 In this embodiment, a mounting sleeve 44 is fixedly connected to one side of each connecting seat 42, and one end of each flow meter 43 is sleeved in the corresponding mounting sleeve 44. A limiting screw 45 is tightened between each mounting sleeve 44 and the corresponding flow meter 43, so as to achieve the effect of quickly installing and removing the flow meter 43, and prevent the flow meter 43 from shaking randomly during operation, thereby avoiding affecting the detection result.

[0028] See also Figure 1 and Figure 3 In this embodiment, a limiting slot 49 is fixedly installed on one side of each connecting seat 42, and a baffle 48 is hinged on each limiting slot 49. A wire through hole 12 is provided on the mounting seat 11 for limiting the wires on the flow meter 43. When in use, the wires connected to the flow meter 43 are placed in the limiting slot 49, and the baffle 48 is rotated to block the open side of the limiting slot 49. The free end of the wire passes through the wire through hole 12 and is electrically connected to the controller 41.

[0029] See also Figure 1In this embodiment, a second threaded connection hole is provided on the weighting object 5, and the second threaded connection hole is threadedly connected to the first connection screw 46 of the bottom connection seat 42. When in use, the weighting object 5 gives all the connection seats 42 a downward gravity, thereby improving the stability and detection accuracy of the flow meter 43. The weighting object 5 can increase the weight of the device, making it more stable in the water flow, reducing the deviation caused by the fluctuation of the water flow; avoiding the deviation of the flow meter 43 due to the influence of the water flow during the detection due to its lightness, thereby causing inaccurate detection results. At the same time, the weighting object 5 can help the flow meter 43 to better locate in the water flow, especially in a complex water flow environment, such as a river, a lake or a reservoir, to ensure that the flow meter 43 can accurately detect the water flow conditions in the target area. It can be seen that the combination of the weighting object 5 and the flow meter 43 can ensure that the flow meter 43 maintains a relatively stable posture during the detection process, thereby improving the accuracy of the detection results. This is particularly important for occasions where high-precision detection of parameters such as water flow velocity and flow rate is required. By reducing inspection errors caused by device drift or instability, weights help improve the reliability and accuracy of overall inspection data.

The rotating paddle 26 and the direction adjustment plate 33 are symmetrically arranged. The motor 21 and the electric articulated seat 32 are both electrically connected to the controller. When in use, the motor 21 is started, and the output shaft of the motor 21 drives the second pulley 25 to rotate, and then the second pulley 25 drives the belt 22, the first pulley 24, the transmission rod 23 and the rotating paddle 26 to rotate accordingly, so that the floating base 1 moves forward or backward; at the same time, by starting the electric articulated seat 32, the direction adjustment plate 33 is swung, and used in conjunction with the rotating paddle 26, the effect of controlling the movement direction of the floating base 1 is achieved. The floating base 1 is automatically transported to the waters that need to be detected through the power source, without manpower, and provides work efficiency and positioning accuracy.

[0031] See also Figure 1In this embodiment, a second bearing 28 is installed between the ear plate 27 and the transmission rod 23 to reduce the friction between the ear plate 27 and the transmission rod 23 and reduce the wear degree of the ear plate 27 and the transmission rod 23.

[0032] The specific usage method of this embodiment is as follows:

[0033] Before use, the relevant information such as the water flow depth to be detected is determined, and the corresponding number of connecting sockets 42 and flow meters 43 are selected accordingly, and then the installation of the entire device is completed.

[0034] When in use, the motor 21 is started, and the output shaft of the motor 21 drives the second pulley 25 to rotate, and then the second pulley 25 drives the belt 22, the first pulley 24, the transmission rod 23 and the rotating paddle 26 to rotate accordingly, so that the floating base 1 moves forward or backward; at the same time, by starting the electric articulated seat 32, the swing direction adjustment plate 33 is used in conjunction with the rotating paddle 26 to achieve the effect of controlling the movement direction of the floating base 1.

[0035] After the velocity meter 43 determines the specific detection position, the motor 21 and the electric articulated seat 32 are turned off, so that the floating base 1 is suspended on the water surface, and the velocity meter 43 is turned on to detect the water flow velocity. The velocity meter 43 transmits the detected relevant information to the controller.

[0036] In summary, the utility model achieves the effect of fully capturing and comparing the flow velocity changes at different depths at the same time point through the mutual cooperation of the floating base 1, the power source, the connecting seat 42, the flow meter 43, the controller 41, the mounting assembly and the mounting through hole, thereby fully reflecting the real situation of the water flow.
