Technical Field

[0001] This utility model relates to the field of ADCP flow measurement technology, specifically a channel bottom-mounted ADCP flow measurement system with flushing function to prevent siltation. Background Technology

[0002] The ADCP (Acoustic Doppler Current Profiler) is an instrument that measures water flow velocity based on the Doppler effect principle. It calculates water flow velocity by emitting sound waves and analyzing the frequency shift of the reflected signals from particles in the water. It supports real-time, self-contained, and remote control modes.

[0003] When current ADCP flow meters measure the velocity of water flow in channels, a corresponding number of ADCP flow meters are evenly installed at the bottom of the channel according to the width of the channel. ADCP flow meters are installed at the bottom of the water for a long time. Due to the flow of water, a certain amount of mud and sand will stick to the surface of the ADCP probe. It is impossible to clean them regularly, which will affect the monitoring effect. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] To address the problems existing in the prior art, this embodiment provides the following technical solution: a channel-based ADCP flow measurement system with flushing function, comprising a channel body 1, mounting bases 5 evenly spaced at the bottom of the channel body 1, an ADCP flow meter 6 mounted on the upper side of the middle of the mounting base 5, and a flushing mechanism 8 mounted on the outer side of the ADCP flow meter 6. The flushing mechanism 8 can periodically flush the probe of the ADCP flow meter 6, ensuring the long-term accuracy of the ADCP flow meter 6 in monitoring water flow. Simultaneously, a portable disassembly mechanism 7 is provided, located on the upper side of the mounting base 5 and on the left and right sides of the ADCP flow meter 6, allowing for quick disassembly of the ADCP flow meter 6 from the upper side of the mounting base 5, reducing the difficulty and time of underwater disassembly.

[0027] like Figures 1-5 As shown, it includes a bracket 2, which is installed on the upper right side of the channel body 1. A control box 3 is installed on the middle right side of the bracket 2, and a solar panel 4 is installed on the top of the bracket 2.

[0028] Based on the width of the channel body 1, mounting bases 5 are set at equal intervals at the bottom of the channel body 1. An ADCP flow meter 6 (model ADCP-V) is installed above the middle of the mounting base 5. Multiple sets of ADCP flow meters 6 are arranged at equal intervals along the width of the channel body 1 at the bottom of the channel body 1. The ADCP flow meter 6 can measure the water flow velocity by emitting sound waves into the channel body 1 and analyzing the change in echo frequency. The flow rate is calculated by using RTU real-time flow velocity detection and stratification information, and then uploaded to the background.

[0029] If the ADCP flow meter 6 is placed inside the channel body 1 for a long time, a large amount of mud and sand will stick to its probe. If the mud and sand are not cleaned, it will affect the final monitoring result of the ADCP flow meter 6.

[0030] A flushing mechanism 8 is provided on the outside of the ADCP flow meter 6. The flushing mechanism 8 includes nozzles 81 that are equidistantly arranged on the outside of the ADCP flow meter 6. The positions of the nozzles 81 correspond one-to-one with the positions of the ADCP flow meter 6. The nozzles 81 are located near the upstream and downstream of the ADCP flow meter 6. The nozzles 81 are located on the outside of the water pipe 82. The water pipe 82 is also arranged in multiple groups laterally along the width of the channel body 1 and is located on one side of each group of ADCP flow meters 6. At the same time, vertical water pipes 82 are provided on the left side of the multiple groups of water pipes 82 for connection. A submersible pump 84 is installed in front of the vertical water pipe 82. An electric valve 83 is provided on the left side of each group of horizontal water pipes 82.

[0031] The submersible pump 84 can be turned on, which can pump water to the interior of the vertical water pipe 82. At the same time as the submersible pump 84 is turned on, the electric valve 83 set on the left side of the horizontal water pipe 82 is also turned on, which allows the water to flow smoothly into the horizontal water pipe and then flow to the nozzle 81, where it is sprayed out. That is, the nozzle 81 can efficiently flush the probe of the ADCP flow meter 6, which can ensure the long-term monitoring results of the ADCP flow meter 6.

[0032] The ADCP flow meter 6 is installed on the upper middle part of the mounting base 5, and its exterior is in close contact with the portable disassembly mechanism 7 set above the ADCP flow meter 6. The portable disassembly mechanism 7 includes a limiting plate 71. The inner side of the limiting plate 71 is in close contact with the exterior of the ADCP flow meter 6. At the same time, a connecting bracket 72 is fixedly installed on the outer middle part of the limiting plate 71. The right side of the connecting bracket 72 is fixedly connected to the mounting base 5, and the front and rear sides of the lower left side of the connecting bracket 72 are slidably connected to the fixing groove opened on the left side inside the mounting base 5.

[0033] Meanwhile, the left end of the middle part of the connecting bracket 72 is tightly fitted to the right end of the limiting post 73. The outer side of the left end of the limiting post 73 is threaded and connected to the threaded hole in the middle of the connecting block 74. The thread on the outer side of the limiting post 73 and the threaded hole in the middle of the connecting block 74 are both fine threads. Compared with coarse threads, fine threads have a smaller helix angle, more threads, more uniform force distribution, and greater friction, which can enhance the self-locking property of the threads. The lower end of the connecting block 74 is fixedly connected to the mounting base 5 for fixation.

[0034] If the ADCP flow meter 6 malfunctions, the limiting post 73 can be turned to loosen the connecting block 74 connected to the thread on the left side of the limiting post 73. Then, the limiting post 73 can be pulled to the left, and the right end of the limiting post 73 will pull the connecting bracket 72 to move together. When the connecting bracket 72 moves, the limiting plate 71 connected on the right side will also move together, which will cause the limiting plate 71 attached to the left side of the ADCP flow meter 6 to detach from the outer left side of the ADCP flow meter 6. At this time, the ADCP flow meter 6 can be pulled upward, and the ADCP flow meter 6 can be detached from the middle of the mounting base 5. The ADCP flow meter 6 can be removed from the mounting base 5 without tools, which effectively reduces the difficulty of underwater disassembly and reduces the disassembly time.

[0035] Meanwhile, the lower ends of the front and rear sides of the connecting frame 72 are slidably connected to the fixing grooves opened in the front and rear of the left side of the mounting base 5. The fixing grooves opened in the front and rear of the left side of the mounting base 5 guide the subsequent movement of the connecting frame 72. A scraping block 75 is installed on its outer side. The outer side of the scraping block 75 is set in a sloping manner, so that it can move along with the connecting frame 72. The inner side of the scraping block 75 is tightly fitted with the inside of the fixing groove opened in the left side of the mounting base 5. That is, when it moves with the connecting frame 72, it can scrape the inside of the fixing groove, which can prevent the accumulation of mud and sand inside the fixing groove.

[0036] The control box 3 is installed on the right side of the middle of the bracket 2. The control box 3 includes a main control board, a communication module and a power module. The power module can supply power to the entire system. The main control board is connected to the flow rate acquisition unit of ADCP flow meter 6 to collect water flow data. The communication module is also connected to the main control board to send the data to the control center.

[0037] Secondly, the drive module of the submersible pump 84 (model 350QJF400-90) is connected to the main control board, and the drive module of the electric valve 83 (model XSDF-500-50) installed on the left side of the water pipe 82 connected to the submersible pump 84 is also connected to the main control board.

[0038] The main control board can send control signals, and the drive module executes specific actions. It can control the submersible pump 84 to open at regular intervals so that it can draw water. After the submersible pump 84 draws water, the electric valve 83 can be activated. The electric valve 83 can control the direction of water flow and transmit the water flow to the nozzle 81 installed on one side of the water pipe 82. It can control the nozzle 81 to spray water to flush the probe of the ADCP flow meter 6 in a sequence from downstream to upstream at regular intervals.

[0039] The main control board uses an embedded microcontroller (model STM32F103C6R8) and a GPRS communication module (model SIM7000);

[0040] The power module includes a lithium battery and a solar panel 4 mounted on the upper part of the bracket 2. The solar panel 4 can absorb solar energy and convert it into electrical energy to provide power to the control box 3 for a long time. It also includes a solar charging controller (model KY5168).

[0041] The working principle of this anti-clogging channel bottom-mounted ADCP flow measurement system with flushing function is as follows: The ADCP flow meter 6 is installed on the mounting base 5 at the bottom of the channel body 1. It can measure the water flow velocity by emitting sound waves and analyzing the changes in echo frequency. A flushing mechanism 8 is set on the outside of the ADCP flow meter 6. The nozzles 81 in the flushing mechanism 8 correspond one-to-one with the positions of the ADCP flow meter 6. The probe of the ADCP flow meter 6 can be flushed at regular intervals to ensure the long-term accurate monitoring results of the ADCP flow meter 6. At the same time, a portable disassembly mechanism 7 is set on the upper side of the mounting base 5. The portable disassembly mechanism 7 is located on the outside of the ADCP flow meter 6, which makes it easy to disassemble the ADCP flow meter 6 from the middle upper side of the mounting base 5. This can effectively reduce the difficulty of underwater disassembly of the ADCP flow meter 6 and reduce the disassembly time of the ADCP flow meter 6.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 claimed utility model.
