Description

Technical Field

[0001] This utility model relates to the field of water flow velocity measurement technology, specifically a waterway water flow velocity measurement and detection device. Background Technology

[0002] A waterway is a designated or constructed navigation channel for ships in rivers, lakes, seas, and other bodies of water. Waterways are the foundation of water transport, the lifeline of ports, and a vital public transportation infrastructure, playing a crucial role in national economic development and national defense. Waterway current velocity measurement refers to measuring the speed of water flow within a waterway. This is of great significance for waterway management, ship navigation safety, and water resource management. By measuring the water flow velocity within a waterway, waterway planning and ship navigation routes can be optimized, improving waterway utilization efficiency and safety.

[0003] Currently, when using turbines to detect river flow velocity, the turbine is usually directly placed into the water flow, and the water flow drives the turbine to rotate. By recording and analyzing the turbine's rotation speed in real time, the flow velocity of the waterway can be calculated. However, in traditional turbine detection methods, the turbine lacks protection and is easily damaged by debris in the river when placed in the water, which affects the accuracy of the detection work.

[0004] To address the aforementioned problems, we propose a waterway flow velocity measurement and detection device. Utility Model Content

[0007] A waterway current velocity measurement and detection device includes a detection box, with detection channels on both sides of the inner cavity of the detection box, detection turbines mounted on the inner middle of the two sets of detection channels via fixing frames, and a water outlet channel between the two sets of detection channels; a first protective net is provided at the inlet end of the detection box, and a second protective net is provided at the inlet end of the detection channel.

[0008] Preferably, a flow divider is provided in the middle of the inner cavity of the detection box. The flow divider is located at the inlet end of the detection box and is installed in the middle in front of the two sets of detection channels.

[0009] Preferably, the inlet end of the distributor is configured with an arc-shaped structure, and the outlet end of the distributor is configured with a conical structure.

[0010] Preferably, the first protective net is configured as an arc-shaped structure, and the second protective net is installed at an angle at the inlet end of the detection channel.

[0011] Preferably, the water outlet channel is located in the middle of the inner cavity of the testing box and between the two sets of testing channels.

[0012] Preferably, the top of the testing box is provided with two sets of connecting tubes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up a first protective net and a second protective net, can perform multi-stage filtration of river water, thereby effectively preventing the detection turbine from being damaged by debris in the river water during operation.

[0018] The technical solution in this application embodiment is to solve the problems mentioned above in the background technology. The overall idea is as follows: The main technical solution of this utility model is that by setting a first protective net 4 at the inlet end of the detection box 1, large debris or fish in the river water can be blocked and filtered. Then, by setting a second protective net 7 at the inlet end of the detection channel 2, small debris and stones can be filtered. The setting of the first protective net 4 and the second protective net 7 can filter the river water in multiple stages, thereby effectively avoiding damage to the detection turbine 5 caused by the impact of debris in the river water during operation. In addition, the water flow velocity is measured by using two sets of detection turbines 5, and finally, centralized analysis is performed, thereby effectively improving the efficiency and accuracy of detecting the water flow velocity in the waterway.

[0019] Example: Refer to Figures 1-2As shown, a waterway current velocity measuring device in this embodiment includes a measuring box 1. The measuring box 1 has measuring channels 2 on both sides of its inner cavity. The measuring channels 2 have measuring turbines 5 installed in the middle of their inner sides by a fixing frame. A water outlet channel 3 is provided between the two measuring channels 2. A first protective net 4 is provided at the inlet end of the measuring box 1, and a second protective net 7 is provided at the inlet end of the measuring channel 2.

[0020] The first protective net 4 is installed to filter out large debris in the water flow of the channel, while the second protective net 7 is mainly used to filter the water flow entering the detection box 1 again, thereby blocking small debris. It mainly protects the detection turbine 5 and prevents debris from impacting and damaging the detection turbine 5 under the action of the water flow.

[0021] A diverter 6 is installed in the middle of the inner cavity of the test chamber 1. The diverter 6 is located at the inlet end of the test chamber 1 and is installed in the middle in front of the two sets of test channels 2. The inlet end of the diverter 6 is set with an arc-shaped structure and the outlet end of the diverter 6 is set with a conical structure. It mainly diverts the river water so that the river water enters the test channels 2 on both sides to flush the test turbine 5.

[0022] In some examples, the first protective net 4 is set as an arc-shaped structure, and the second protective net 7 is installed at an angle at the inlet end of the detection channel 2. The first protective net 4 can filter and block large debris in the water flow of the channel, preventing large debris from entering the detection box 1 and causing damage.

[0023] In some examples, the water outlet channel 3 is located in the middle of the inner cavity of the detection box 1 and between the two sets of detection channels 2, mainly for discharging the debris filtered down by the second protective net 7.

[0024] In some examples, the top of the detection box 1 is provided with two sets of connecting tubes 8 for connecting to external devices, so that the external devices can put the detection box 1 into the river for testing.

[0025] The working principle of this utility model is as follows:

[0026] In use, the device is first fixedly connected to the external lifting device via the connecting tube 8. Then, the device is deployed into the waterway via the external lifting device. The first protective net 4 should face upstream. The first protective net 4 mainly serves to block and protect against large debris or fish in the river water from entering the detection box 1 and causing the detection turbine 5 to break. After the filtered river water enters the detection box 1, it is first diverted by the diverter 6, causing the river water to flow to both sides. Then, it enters the detection channel 2 through the second protective net 7, which washes the detection turbine 5 and drives it to rotate. By recording the rotation speed of the detection turbine 5 in real time, the flow velocity of the waterway can be calculated.

[0027] The second protective net 7 is installed at an angle, and its mesh is smaller than that of the first protective net 4. It mainly filters out small sand, gravel and fish debris. The filtered debris will flow along the angle of the second protective net 7 under the flushing of the river water and finally converge into the outlet channel 3 for discharge, thus effectively protecting the detection turbine 5 and enhancing its safety during operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
