Abstract
Description
Technical Field
[0001] This utility model relates to the field of ADCP flow measurement technology, specifically a dynamic sediment deposition channel lifting multi-probe ADCP flow measurement system. Background Technology
[0002] ADCP (Acoustic Doppler Current Profiler) is an instrument that uses the acoustic Doppler principle to measure the velocity and velocity profile of water flow. It obtains water flow velocity information by analyzing the Doppler frequency shift of suspended particles in the water.
[0003] Currently, when measuring water flow, multiple ADCP flow meters and mud level gauges need to be installed on the outside of a lifting mechanism support. The support is raised and lowered by the lifting mechanism, so that the ADCP flow meters and mud level gauges installed on the support can be placed in the channel for detecting water level, flow rate and mud level in the channel. In order to ensure the installation of multiple ADCP flow meters and mud level gauges, a horizontal support is usually used. However, the horizontal support is usually placed in the water along with the ADCP flow meters and mud level gauges. When the water moves, foreign objects in the water will be suspended on the support. The foreign objects are difficult to clean and will affect the detection of ADCP flow meters and mud level gauges installed on the outside of the support. Utility Model Content

[0022] 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.
[0023] To address the problems existing in the prior art, this embodiment provides a dynamic sediment deposition channel lifting multi-probe ADCP flow measurement system. The system comprises a channel body 1 and a supporting crossbeam 5. The supporting crossbeam 5 is positioned above the middle of the channel body 1, and a lifting mechanism 6 is installed in the middle of the crossbeam 5. A crossbar 11 is fixedly connected to the lower end of the lifting mechanism 6. A monitoring mechanism 9 is installed on the lower side of the crossbar 11. The lifting mechanism 6 can adjust the height of the monitoring mechanism 9, allowing it to enter the water inside the channel body 1 to effectively detect the water flow velocity and sediment level. Vertical rods 8 are set at equal intervals on the lower side of the horizontal rod 11. An automatic foreign object cleaning mechanism 7 is set at the connection between the vertical rod 8 and the horizontal rod 11. The automatic foreign object cleaning mechanism 7 can make the vertical rod 8 rotate 90° along the water flow direction. Using the impact force of the water flow inside the channel body 1, the foreign objects hanging on the vertical rod 8 can be cleaned. There are two operation methods. Another operation method is to turn on the motor 74 set in the automatic foreign object cleaning mechanism 7. The motor 74 will make the vertical rod 8 rotate at high speed. Centrifugal force can be used to shake off the mud and sand adhering to the outside of the vertical rod 8, so as to achieve self-cleaning of the surface of the vertical rod 8.
[0024] like Figures 1-4As shown, it includes a bracket 2, which is installed on the upper side of the channel body 1. A control box 3 is installed on the upper left side of the middle of the bracket 2. A solar panel 4 is installed on the top of the bracket 2. Meanwhile, a support crossbeam 5 is fixed to the bottom of the bracket 2 by bolts. The support crossbeam 5 is located on the upper side of the channel body 1 and spans the upper sides of the channel body 1.
[0025] A lifting mechanism 6 is installed in the middle of the supporting crossbeam 5. A crossbar 11 is fixedly installed at the bottom of the lifting mechanism 6. Three sets of vertical bars 8 are equally spaced inside the lower side of the crossbar 11. A monitoring mechanism 9 is installed at the lower end of each set of vertical bars 8. That is, the lifting mechanism 6, the automatic foreign object cleaning mechanism 7, the vertical bars 8, the monitoring mechanism 9 and the crossbar 11 are all located in the upper middle part of the channel body 1.
[0026] The lifting mechanism 6 includes a fixed frame 61, with a lead screw 62 rotatably connected to the middle of the fixed frame 61. A motor 63 is fixedly connected to the top of the lead screw 62, and a movable frame 64 is threadedly connected to the external side of the lead screw 62. The left and right sides of the movable frame 64 are slidably connected to the left and right sides inside the fixed frame 61. A crossbar 11 is fixedly connected to the bottom of the movable frame 64. By turning on the motor 63, the lead screw 62 can rotate inside the fixed frame 61. When the lead screw 62 rotates, the externally threaded movable frame 64 moves up and down. A horizontal bar 11 is fixedly connected to the end of the channel body 1. A vertical bar 8 is set on the lower side of the inside of the horizontal bar 11. An automatic foreign object removal mechanism 7 is set at the connection between the vertical bar 8 and the horizontal bar 11. A monitoring mechanism 9 is set on the lower side of the vertical bar 8. That is, when the moving frame 64 moves downward, it can push the automatic foreign object removal mechanism 7, the vertical bar 8, the monitoring mechanism 9 and the horizontal bar 11 set on the lower side to move downward, so that the vertical bar 8 moves to contact the water level line 10 on the inner side of the channel body 1 and then moves downward, ensuring that the horizontal bar 11 will not enter the lower side of the water level line 10. At this time, the monitoring mechanism 9 set at the lower end of the vertical bar 8 will enter the water in the channel body 1.
[0027] The monitoring mechanism 9 includes a mounting frame 91, an ADCP flow meter 92, and a sludge level gauge 93. The ADCP flow meter 92 is installed on the lower front side of the vertical rod 8. The mounting frame 91 is bolted to the lower end of the vertical rod 8. The sludge level gauge 93 is installed inside the mounting frame 91. Three sets of ADCP flow meters 92 and sludge level gauges 93 are installed on the lower side of the horizontal rod 11 through the vertical rod 8. The lower side of each set is equipped with an ADCP flow meter 92 and a sludge level gauge 93. The ADCP flow meter 92 is of the ADCP-V type. It measures the water flow velocity by emitting sound waves into the channel body 1 and analyzing the change in echo frequency. The sludge level gauge 93 accurately measures the thickness of the underwater sludge layer and the interface position by analyzing the echo characteristics of ultrasonic or radar signals. The sludge level gauge 93 and the sludge level gauge 94 use RTU to detect real-time flow velocity, sediment concentration and stratification information and calculate flow rate, and upload the data to the background.
[0028] Secondly, an automatic foreign object removal mechanism 7 is set between the horizontal bar 11 and the vertical bar 8. The automatic foreign object removal mechanism 7 is installed on the upper side of the horizontal bar 11. The automatic foreign object removal mechanism 7 includes a protective cover 76, which is fixedly installed on the upper end of the horizontal bar 11. Its interior is set as a cavity. Two sets of central synchronous pulleys 71 are set in the middle of the protective cover 76. The outside of each set of central synchronous pulleys 71 is engaged with a synchronous belt 72. The left side of the synchronous belt 72 engaged with the lower outer side of the central synchronous pulley 71 is engaged with a left synchronous pulley 73. The right side of the synchronous belt 72 engaged with the upper outer side of the central synchronous pulley 71 is engaged with a right synchronous pulley 75. At the same time, the lower middle side of the central synchronous pulley 71, the left synchronous pulley 73, and the right synchronous pulley 75 are all fixedly connected to the vertical bar 8. In addition, the upper middle side of the central synchronous pulley 71 is connected to the output shaft of the second motor 74.
[0029] When motor 74 is turned on, the central synchronous pulley 71 will rotate. When the central synchronous pulley 71 rotates, the externally meshing synchronous belt 72 will also rotate. The left synchronous pulley 73 and the right synchronous pulley 75 meshing on the inner side of the synchronous belt 72 will also rotate. That is, the vertical rod 8 installed in the middle of the central synchronous pulley 71, the left synchronous pulley 73 and the right synchronous pulley 75 will also rotate together.
[0030] When the vertical rod 8 is submerged in water for a long time, the water flow will cause foreign objects to hang on the outside. After the vertical rod 8 is lowered into the water at regular intervals, it can rotate 90° along the direction of water flow. The impact force of the water flow inside the channel body 1 can automatically clean up the foreign objects hanging on the outside of the vertical rod 8.
[0031] The control box 3, installed on the upper left side of the middle of the bracket 2, 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 ADCP flow meter 92 flow velocity acquisition unit and the sludge level gauge 93 sludge thickness acquisition unit to collect water flow data. The motor (model Z4-180-21) is connected to the main control board through the motor drive module. The communication module is also connected to the main control board to send data to the control center.
[0032] The main control board uses an embedded microcontroller (model STM32F103C6R8) and a GPRS communication module (model SIM7000);
[0033] 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).
[0034] The working principle of this dynamic sediment deposition channel lifting multi-probe ADCP flow measurement system is as follows: A supporting crossbeam 5 is set up, and a lifting mechanism 6 is set in the middle of the supporting crossbeam 5. The bottom of the lifting mechanism 6 is fixedly connected to a crossbar 11. Multiple sets of vertical bars 8 are set on the lower side of the crossbar 11. A monitoring mechanism 9 is installed at the lower end of each set of vertical bars 8, which allows multiple sets of monitoring mechanisms 9 to monitor the water flow in the channel body 1 at multiple points. By setting up the lifting mechanism 6, the monitoring mechanism 9 can be raised and lowered, so that it can enter the lower side of different water level lines 10 to monitor the water flow in the channel body 1. At the same time, an automatic foreign object removal mechanism 7 is set at the connection between the vertical bar 8 and the crossbar 11. The automatic foreign object removal mechanism 7 can make the vertical bar 8 and the monitoring mechanism 9 rotate, so that the vertical bar 8 can rotate 90° along the direction of water flow. The impact force of the water flow inside the channel body 1 can automatically remove foreign objects hanging on the outside of the vertical bar 8.
[0035] 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.
