[0014] A method for using a device for automatically monitoring a river flow rate, flow rate, and water level, comprising the following steps: Step 1: Place the entire device in water or on the water surface and start the drive motor. The drive motor drives the cam to rotate, and the horizontal slide bar slides through contact; Step 2: When the horizontal slide bar slides, it drives the rotating scraper bar to rotate, pushing away the obstacle blocking the front of the large-pore filter screen through contact; Step 3: When the scraper rotates, the inclined hammer head is driven to slide through the contact. After the contact is broken, the inclined hammer head is quickly reset under the elastic potential energy of the coarse spring to knock on the large-pore filter screen to vibrate and remove surface attachments.

[0015] The present invention provides a device for automatically monitoring river flow rate, flow rate, and water level, and a method for using the device. The device has the following beneficial effects: (1) This invention drives the cam and the horizontal slide bar to rotate back and forth by driving the motor, thereby realizing that when a large obstacle appears in front of the large-pore filter, it can be pushed away in time by the swing of the rotating scraper bar, thus avoiding the obstacles in the water flow affecting the water flow through the sensor and causing large errors in the monitoring results. At the same time, when the rotating scraper bar swings, it drives the inclined hammer head to hit the large-pore filter, causing the large-pore filter to vibrate and remove attachments such as water plants attached to the large-pore filter, further ensuring the stability of the monitoring results during the operation of the device.

[0016] (2) This invention achieves the cleaning effect of the bottom of the depth sensor by driving the gear and the cleaning block through the rack, avoiding the occurrence of obstacles at the bottom of the depth sensor and the failure to clean it in time, which leads to inaccurate monitoring results or even failure to monitor. At the same time, the gear drives the rotating top rod and the cleaning rubber to rotate through the transmission wheel, achieving the cleaning effect on the surface of the speed sensor, avoiding the adhesion of pollutants such as mud, sand or oil to the sensor surface after the device has been working for a long time, which leads to deviation in the monitoring results, and improving the accuracy of the device's monitoring.

[0017] (3) This invention drives the telescopic top rod and the transmission lever to rotate back and forth by rotating the top rod. During the swinging process of the vibration rod, the connecting base is vibrated by knocking contact, which prevents the rotation speed of the curved fan blade from decreasing due to excessive mud and sand adhering to the surface of the device after long-term continuous operation, thereby affecting the monitoring results. The inner shaft drives the rotating dial to rotate and then drives the curved sliding rod and the limit top rod to slide. The limit top rod and the transmission lever form a limit so that they cannot rotate. It is achieved that the vibration rod will be triggered to swing only when the inner shaft stops rotating or the rotation speed drops significantly, further improving the stability of the device under more extreme conditions.

A fixed plate is installed, and a coarse spring 406 is rotatably installed on the top of the fixed plate. A bevel hammer 407 is fixedly connected to the top of the coarse spring 406. A depth sensor 5 is fixedly installed on the bottom of the periphery 1 of the device. The driving motor drives the cam 401 and the horizontal slide bar 402, and finally drives the rotating scraper 404 to rotate back and forth, so that when a large obstacle appears in front of the large-pore filter 405, it can be pushed away in time by the swing of the rotating scraper 404, avoiding the obstacles in the water flow affecting the water flow through the sensor, thereby causing large errors in the monitoring results. When the rotating scraper 404 swings, it drives the bevel hammer 407 to knock on the large-pore filter 405, causing the large-pore filter 405 to vibrate to remove attachments such as water plants attached to the large-pore filter 405.

[0022] A waterproof baffle is provided on the periphery of the driving motor to protect the motor so that the motor can work normally even under water. The horizontal slide bar 402 is located on the motion track of the cam 401, so that the rotation of the cam 401 is converted into the sliding of the horizontal slide bar 402. A vortex spring is provided between the rotating scraper 404 and the rotating seat 403, so that after the cam 401 is out of contact with the horizontal slide bar 402, the rotating scraper 404 can be restored to its initial position in time, and the rotating scraper 404 is in contact with the large-pore filter 405, so that the rotating scraper 404 can achieve the large-pore filter through contact. The cleaning effect of the surface of 405, the large-pore filter 405 contacts the inclined hammer head 407, so that the inclined hammer head 407 can drive the large-pore filter 405 to vibrate during the resetting process. The inclined hammer head 407 is located on the motion trajectory of the rotating scraper 404, so that the rotation energy of the rotating scraper 404 is converted into the sliding of the inclined hammer head 407, so that the coarse spring 406 can store elastic potential energy. A spiral spring 2 is provided between the coarse spring 406 and the fixed plate, so that after the rotating scraper 404 is reset, the coarse spring 406 can promptly drive the inclined hammer head 407 to reset together.

[0023] A method for using a device for automatically monitoring a river flow rate, flow rate, and water level, comprising the following steps: Step 1: Place the entire device in water or on the water surface and start the drive motor, which drives the cam 401 to rotate, and drives the horizontal slide bar 402 to slide through contact; Step 2: When the horizontal slide bar 402 slides, it drives the rotating scraper 404 to rotate, pushing away the obstacle blocking the front of the large-pore filter 405 through contact; Step 3: When the scraper bar 404 rotates, it drives the inclined hammer head 407 to slide through contact. After the contact is broken, the inclined hammer head 407 quickly resets under the elastic potential energy of the thick spring 406 to knock the large-pore filter screen 405 to vibrate and remove surface attachments.

[0024] During operation: When using the device, place the entire device in water or on the water surface and start the drive motor. The driving motor drives the cam 401 to rotate. During the rotation of the cam 401, the horizontal slide bar 402 is driven to slide through contact. The sliding of the horizontal slide bar 402 drives the rotating scraper 404 to rotate. During the rotation of the rotating scraper 404, the surface obstacles of the large-pore filter screen 405 are scraped off through contact. At the same time, during the rotation of the rotating scraper 404, the inclined hammer head 407 is driven to slide forward through contact. After the inclined hammer head 407 slides backward, the coarse spring 406 is bent and elastic potential energy is stored. After the rotating scraper 404 continues to rotate, it is disengaged from the inclined hammer head 407. After disengagement, the coarse spring 406 stores elastic potential energy, so it drives the inclined hammer head 407 to slide backward. During the resetting process of the inclined hammer head 407, it contacts the large-pore filter screen 405 and drives it to vibrate, thereby avoiding the entanglement of water plants and other debris in the large-pore filter screen 405 in the water flow, resulting in large errors in the monitoring results, thereby ensuring the accuracy of the monitoring device. After the cam 401 continues to rotate, it disengages from the horizontal slide bar 402. After disengaging from the contact, the rotating scraper 404 rotates in the opposite direction to that just now under the rebound force of the spiral spring to restore to the initial position. During the resetting process of the rotating scraper 404, the inclined hammer head 407 is driven to rotate through the contact. The rotating scraper 404 continues to rotate to disengage from the inclined hammer head 407. After disengaging from the contact, the inclined hammer head 407 is driven by the thick spring 406 to rotate under the rebound force of the spiral spring 2 to restore to the initial position.

During the swinging process of the vibration rod 904, the connecting base is vibrated by knocking contact, thereby avoiding the device from having too much mud and sand attached to the surface of the curved fan blade after long-term continuous operation, resulting in a reduction in its rotation speed, thereby affecting the monitoring results.

At the same time, the rotation of the gear 603 drives the transmission wheel 1 605 to rotate, and the rotation of the transmission wheel 1 605 drives the transmission wheel 2 606 to rotate through the transmission belt, and the transmission wheel 2 606 The rotation of the drive wheel 606 drives the cleaning rubber 609 to rotate together. Since the arc top block 608 is driven to slide upward when the rotary push rod 607 rotates, the cleaning rubber 609 contacts the top of the arc top block 608, causing it to swing upward while rotating. The cleaning rubber 609 contacts the speed sensor 8 during the movement, thereby cleaning its surface, preventing pollutants such as mud, sand, or oil from adhering to the sensor surface after the device has been working for a long time, resulting in deviations in the sensor monitoring results or even failure to monitor.

[0032] At the same time, during the rotation of the rotating top rod 607, the telescopic top rod 901 is driven to slide backward through contact. The sliding of the telescopic top rod 901 drives the bottom of the transmission lever 902 to rotate backward through contact. When the bottom of the transmission lever 902 rotates backward, its top rotates forward, thereby driving the bottom of the vibration rod 904 to rotate forward together through the wire rope 903. When the bottom of the vibration rod 904 rotates forward, its top rotates backward. During the backward rotation of the top of the vibration rod 904, it contacts the connection base and drives it to vibrate. The vibration of the connection base drives the inner rotating shaft 7 and the arc fan blades to vibrate, thereby achieving when the device causes too much mud and sand to adhere to the surface of the arc fan blade after long-term continuous work, the attachments on its surface can be removed as much as possible through vibration, thereby improving the stability of the device during operation. At the same time, when the inner rotating shaft 7 rotates, it drives the rotating dial 905 to rotate together. When the rotating dial 905 rotates, it drives the arc sliding rod 906 to slide downward through contact. When the arc sliding rod 906 slides downward, it drives the limiting top rod 907 to slide forward through contact. After the limiting top rod 907 slides forward, its front part contacts the transmission lever 902 and forms a limit so that it cannot continue to rotate. When the transmission lever 902 cannot continue to rotate, the vibration rod 904 cannot continue to rotate. Therefore, the sand removal device will be triggered only when the inner rotating shaft 7 stops rotating or its speed is greatly reduced, further improving the overall stability of the device.
