Description

[0001] This utility model relates to the technical field of water flow velocity measurement, specifically providing a measuring device for detecting water flow velocity at different water depths. Background Technology

[0002] Water flow velocity is one of the hydrological characteristics of rivers. Accurately understanding water flow velocity helps analyze the current state of the river, facilitating comprehensive river management and reducing the likelihood of hydrological disasters. Furthermore, understanding the water flow velocity at different depths helps to more accurately understand the distribution of water flow velocity and the river's runoff.

[0003] Currently, contact-type measuring equipment is generally used to measure the flow velocity at different depths in the river. Different flow velocity measuring instruments are placed at different depths in the river channel to measure the flow velocity at these depths. This method requires the deployment of multiple flow velocity measuring instruments, resulting in high equipment costs and high labor costs for deployment and retrieval.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0027] To address the issue of high overall cost of equipment used for measuring water flow velocity at different depths, this invention provides a measuring device for detecting water flow velocity at different depths. For example... Figure 1 As shown, the measuring device includes a main rope 1, a climbing mechanism 6, and a flow velocity meter 3. The flow velocity meter 3 is connected to the climbing mechanism 6 to measure the water flow velocity at the depth where the climbing mechanism 6 is located. The climbing mechanism 6 works in conjunction with the main rope 1 and can move along the main rope 1 to different depths of water flow, thereby obtaining the water flow velocity at different depths. The measuring device provided by this invention uses only one flow velocity meter 3 for continuous measurement at different water depths, resulting in lower equipment costs. Furthermore, the device only requires the deployment and retrieval of one main rope 1, reducing labor and time costs.

[0028] A counterweight can be installed at the end of the main rope 1 to ensure that the end of the main rope 1 is located at the bottom of the river channel, and also to help maintain the stability of the main rope 1. The current measuring instrument 3 can be any one of a propeller current meter, a turbine current meter, or an electromagnetic current meter.

[0029] like Figure 2 and Figure 3 As shown, the climbing cable mechanism 6 includes a first support 61 and a second support 62. The first support 61 is equipped with a drive wheel 64 and a drive motor 63 for driving the drive wheel 64 to rotate. The second support 62 is equipped with a driven wheel 65. The drive wheel 64 and the driven wheel 65 cooperate to clamp the main rope 1 between them. The drive wheel 64 is rotatably connected to the first support 61, and the driven wheel 65 is rotatably connected to the second support 62. To prevent the main rope 1 from detaching from the drive wheel 64 and the driven wheel 65, grooves are provided on the wheel surfaces of both the drive wheel 64 and the driven wheel 65, and the main rope 1 is located within these grooves. When the drive motor 63 rotates, it drives the drive wheel 64 to rotate. The friction between the drive wheel 64 and the driven wheel 65 and the main rope 1 causes the first support 61 and the second support 62 to move along the main rope 1, allowing the climbing cable mechanism 6 and the flow velocity measuring instrument 3 to be positioned at different water depths to measure the water flow velocity at different depths.

[0030] To increase the friction between the driving wheel 64 and the driven wheel 65 and the main rope 1, dot-shaped protrusions can be set on the wheel surfaces of the driving wheel 64 and the driven wheel 65. Of course, other forms of friction textures can also be set.

[0031] In some examples, a fixed structure (such as a non-removable structure like welding) can be set between the first support 61 and the second support 62 to maintain the clamping effect of the driving pulley 64 and the driven pulley 65 on the main rope 1, ensuring sufficient friction between the main rope 1 and the driving pulley 64 and the driven pulley 65. Before use, the main rope 1 can be placed above the driving pulley 64 and the driven pulley 65. After starting the rotation of the driving pulley 64, the friction will move the main rope 1 between the driving pulley 64 and the driven pulley 65 before measurement operations are performed.

[0032] In other examples, the first bracket 61 and the second bracket 62 can be hinged, opening and closing by rotation, thus facilitating the installation of the main rope 1 between the driving pulley 64 and the driven pulley 65. The first bracket 61 and the second bracket 62 are equipped with a locking structure, which secures them in a closed state, keeping the driving pulley 64 and the driven pulley 65 clamping the main rope 1. After the locking structure is released, the first bracket 61 and the second bracket 62 can be rotated open, facilitating the disassembly or installation of the main rope 1. The locking structure is a conventional locking structure, such as a snap-fit ​​structure or a bolt-fixed structure, and this invention does not specifically limit it to this type.

[0033] The climbing mechanism 6 may also include at least one set of auxiliary wheels, each set comprising two auxiliary wheels 66, which are rotatably connected to the first support 61 and the second support 62, respectively. After the first support 61 and the second support 62 are fixed, the two auxiliary wheels 66 clamp the main rope 1. The main function of the auxiliary wheels is to increase the number of engagement points between the climbing mechanism 6 and the main rope 1, thereby increasing the stability of the climbing mechanism 6 as it moves along the main rope 1. The friction between the auxiliary wheels and the main rope 1 can be less than the friction between the driving wheel 64 and the driven wheel 65 and the main rope 1, thus reducing the resistance to the climbing mechanism 6 moving along the main rope 1.

[0034] A rope groove can also be provided on the auxiliary wheel 66 to allow the auxiliary wheel 66 to clamp the main rope 1 and prevent the main rope 1 from detaching from the auxiliary wheel assembly.

[0035] In addition, a pressure sensor is installed on the climbing mechanism 6, which can measure the water depth where the climbing mechanism 6 is located. Specifically, the pressure sensor is used to measure the water pressure at the water depth where the climbing mechanism 6 is located, and then the processing module calculates the water depth based on the water pressure.

[0036] Of course, in other examples, the climbing cable mechanism 6 can also estimate the water depth based on the distance it moves on the main rope 1, but this estimation method has a certain degree of error.

[0037] In addition, the measuring device includes a flow guide stabilizer 2, which is configured to maintain a stable posture in the water flow. The flow velocity meter 3 is connected to the climbing cable mechanism 6 through the flow guide stabilizer 2, thereby improving the stability of the flow velocity meter 3 in the water flow by utilizing the flow guide stabilizer 2 to maintain a stable posture in the flowing water.

[0038] Specifically, such as Figure 1 As shown, the flow guide stabilizer 2 is teardrop-shaped, with a head, a middle section, and a tail. The flow velocity measuring instrument 3 is connected to the tail of the flow guide stabilizer 2 via a first connector 4, and the head of the flow guide stabilizer 2 is connected to the climbing cable mechanism 6 via a second connector 5. The middle section of the flow guide stabilizer 2 has the largest diameter. Along the axis of the flow guide stabilizer 2, the diameter gradually decreases from the middle section towards the head and from the middle section towards the tail, with the diameter of the head changing at a greater rate than that of the tail. When the flow guide stabilizer 2 is placed in a flowing fluid, it maintains a stable posture, specifically with the head facing the tail in the same direction as the water flow. Furthermore, the teardrop-shaped flow guide stabilizer 2 exhibits better stability in water, maintaining a stable posture even in high-velocity water flows, making it more suitable for measuring flow velocity in deep-water environments.

[0039] At least a portion of the first connecting parts 4 are tensioned and distributed on the same conical surface, and the axial direction of this conical surface coincides with the axial direction of the flow guide stabilizer 2 and the axial direction of the flow velocity meter 3. After the flow guide stabilizer 2 maintains a stable posture in the water flow, the first connecting parts 4 are tensioned, so that the axial direction of the flow velocity meter 3 coincides with the axial direction of the flow guide stabilizer 2 and is parallel to the water flow direction. At this time, the water flows perpendicularly through the flow velocity meter 3, and the measurement accuracy of the flow velocity meter 3 is the highest.

[0040] The first connector 4 is made of a rigid material (such as plastics like polyvinyl chloride or metals with supporting capabilities), which can effectively maintain the structural stability of the flow velocity meter 3 and the flow guide stabilizer 2. Of course, in other possible examples, the first connector 4 can also be made of a soft material (such as ropes). After the flow velocity meter 3 is impacted by water flow, the first connector 4 will be stretched and tightened to ensure the stability of the flow velocity meter 3.

[0041] In summary, the working principle of this utility model is as follows:

[0042] First, release the locking structure, open the first bracket 61 and the second bracket 62, and place the main rope 1 in the rope groove of the driving wheel 64 and the auxiliary wheel 66. Then close the first bracket 61 and the second bracket 62, so that the main rope 1 is accommodated between the driving wheel 64 and the driven wheel 65 and between the two auxiliary wheels 66. Then lock the locking structure to keep the first bracket 61 and the second bracket 62 in a closed state.

[0043] The main rope 1, the climbing mechanism, the flow guide stabilizer 2, and the flow meter are placed in the water. The end of the main rope 1 sinks to the bottom of the riverbed under the action of the counterweight. Then, the drive motor 63 is started, which drives the drive wheel 64 to rotate. The friction between the drive wheel 64 and the driven wheel 65 and the main rope 1 drives the first support 61 and the second support 62 to move along the main rope 1. This allows the climbing mechanism 6 and the flow meter 3 to be at different water depths to measure the flow velocity at different depths.

[0044] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
