Description

Technical Field

[0001] This utility model belongs to the field of flow velocity measurement technology, specifically relating to a hydrological cableway flow measurement device. Background Technology

[0002] Hydrological cableways are devices used to monitor the hydrological environment. They can transport monitoring equipment to a designated location via cables and are one of the commonly used auxiliary monitoring devices in hydrological monitoring. They are generally installed on rivers with relatively rapid currents and large spans between the two banks.

[0003] Flow velocity is a crucial data point in hydrological monitoring. Changes in flow velocity can reveal information about the river channel and its impact on the banks. Current monitoring primarily focuses on measuring surface flow velocity. However, underwater flow also exists, and the velocities differ between the surface and underwater sections. Current monitoring equipment cannot simultaneously measure both surface and underwater flow velocities. Separate measurements result in time lags, significantly reducing the accuracy of data comparison. Therefore, a hydrological cableway flow measurement device is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a hydrological cableway flow measurement device, which can effectively solve the above problems.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: This utility model provides a hydrological cableway flow measurement device, including a water surface detection plate, an underwater detection plate is set directly below the water surface detection plate, a storage groove is opened in the middle of the side wall opposite to the underwater detection plate on the water surface detection plate, an electric telescopic rod is detachably connected to the middle of the top side wall of the storage groove, and a flow velocity detector is detachably connected to the output end of the electric telescopic rod; an installation groove is opened on the side wall away from the water surface detection plate and near the four corners of the underwater detection plate, a rotating column is rotatably connected in the installation groove, and a speed monitoring instrument is connected to the rotating column.

[0006] As a preferred technical solution of this utility model, a pair of fixing plates are fixedly connected to the top of the water surface detection plate and near both side edges. A unwinding column is rotatably connected between the two opposite sides of each pair of fixing plates near the top. A driver is connected to the outer wall of one of the fixing plates. One end of the unwinding column is detachably connected to the output end of the driver.

[0007] As a preferred technical solution of this utility model, a hoisting rope is wound and connected to the unwinding column, and a through hole is opened in the side wall of the water surface detection plate located between each pair of fixed plates. One end of the hoisting rope passes through the through hole and is detachably connected to the top side wall of the underwater detection plate.

[0008] As a preferred technical solution of this utility model, a limiting plate is detachably connected to the bottom of the water surface detection plate and the side walls on both sides of the suspension rope. The limiting plate has a movable groove inside, and a telescopic plate is telescopically connected in the movable groove. An airbag is fixedly connected to the top side wall of the movable groove. One end of the telescopic plate located in the limiting plate is fixedly connected to the bottom end of the airbag, and the bottom end of the telescopic plate is detachably connected to the top side wall of the underwater detection plate.

It also avoids the inaccuracy of the comparison data due to the time difference of separate detection, so as to accurately determine the changes in hydrological conditions.

[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] Please refer to the following: Figures 1-4 This utility model discloses a hydrological cableway flow measurement device, including a water surface detection plate 1, an underwater detection plate 10 directly below the water surface detection plate 1, a storage groove 11 is provided in the middle of the side wall opposite to the underwater detection plate 10 on the water surface detection plate 1, an electric telescopic rod 12 is detachably connected to the middle of the top side wall inside the storage groove 11, a flow velocity detector 13 is detachably connected to the output end of the electric telescopic rod 12, and an installation groove 14 is provided in the side wall away from the water surface detection plate 1 and close to the four corners on the underwater detection plate 10, a rotating column 15 is rotatably connected in the installation groove 14, and a speed monitoring instrument is connected to the rotating column 15.

[0020] A pair of fixed plates 2 are fixedly connected to the top and near the two side edges of the surface detection plate 1. A unwinding column 4 is rotatably connected between the opposite sides of each pair of fixed plates 2 near the top. An actuator is connected to the outer wall of one of the fixed plates 2. One end of the unwinding column 4 is detachably connected to the output end of the actuator. The actuator is used to drive the unwinding column 4 to rotate in either the forward or reverse direction. This application does not limit the specific structure or model of the actuator, as long as it can drive the unwinding column 4 to rotate. A lifting rope 5 is wound and connected to the unwinding column 4. A through hole is provided in the side wall of the surface detection plate 1 located between each pair of fixed plates 2. One end of the lifting rope 5 passes through the through hole and is detachably connected to the top side wall of the underwater detection plate 10.

[0021] The technical effect of this solution is as follows: Because the underwater detection plate 10 is connected to the surface detection plate 1, the surface detection plate 1 and the underwater detection plate 10 can be sent to a designated location together via a cableway. Then, the underwater detection plate 10 is lowered and sent underwater via the unwinding column 4 and the hoisting rope 5. Through the four rotating columns 15 connected to the bottom of the underwater detection plate 10 and the flow velocity detector 13 connected to the bottom side wall of the surface detection plate 1, the function of synchronous detection of surface and underwater flow velocity can be realized. Because it is carried out simultaneously, the reliability of the data can be guaranteed, and the data will be inconsistent due to separate detection, so that the relevant hydrological change information cannot be inferred.

[0022] A limiting plate 8 is detachably connected to the bottom of the surface detection plate 1 and the side walls on both sides of the hoisting rope 5. The limiting plate 8 has a movable groove 16 inside, and a telescopic plate 9 is telescopically connected inside the movable groove 16. An airbag 17 is fixedly connected to the top side wall inside the movable groove 16. One end of the telescopic plate 9 inside the limiting plate 8 is fixedly connected to the bottom end of the airbag 17. The bottom end of the telescopic plate 9 is detachably connected to the top side wall of the underwater detection plate 10. Trapezoidal connecting plates 6 are fixedly connected to both sides of the top of the surface detection plate 1. A connecting plate 7 is fixedly connected to the top of the connecting plate 6. The surface detection plate 1 is connected to the cableway through the connecting plate 7.

[0023] The technical effects of this solution are as follows: the limiting plate 8 and the telescopic plate 9 can limit the underwater detection plate 10, preventing it from tilting or swaying due to impacts during lifting, lowering, and underwater operations, thus ensuring the stability of the underwater detection plate 10 and enabling effective detection. The lifting and lowering of the underwater detection plate 10 is achieved through the unwinding column 4 and the hoisting rope 5, allowing the underwater detection plate 10 to be lowered to different water depths as needed, thereby improving the flexibility of the detection.

[0024] Specifically, in use, this utility model connects four rotating columns 15 to the bottom sidewall of the underwater detection plate 10 via four mounting slots 14, with only half of each rotating column 15 exposed. When the underwater water flows through, it impacts the exposed portion, causing it to rotate. This avoids the rotating column 15 from being fully in contact with the water flow, which would obstruct its rotation and affect the final data. The rotational speed of the rotating column 15 is obtained by the installed speed monitoring instrument, and the water flow velocity is calculated accordingly. The four rotating columns 15 can detect four directions, improving the reliability of the data. After the underwater detection plate 10 is placed underwater, the flow velocity detector 13 installed on the surface detection plate 1 will be opposite the water surface, thus detecting the surface flow velocity. The above method enables the simultaneous detection of surface and underwater flow velocities, ensuring the timeliness of the data and improving the reliability of data comparison, facilitating timely detection of changes in the surrounding hydrology.

[0025] Since it is placed in water, water will inevitably enter the movable groove 16. Therefore, an airbag 17 is set up to prevent water from entering. When the telescopic plate 9 retracts, it squeezes the movable groove 16, thereby deforming the airbag 17 to squeeze the water out from the limiting plate 8.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0027] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
