Description

Technical Field

[0001] The utility model belongs to the technical field of hydrological monitoring, and specifically relates to a micro-hydrological sensor array for a particle tracking and tracing system. Background Art

[0002] In fields such as water resource management, water pollution control and hydrological disaster early warning, the particle tracking and tracing system has become a core technical means for tracing pollution sources and analyzing hydrological cycle rules by virtue of its ability to accurately simulate the migration and diffusion trajectories of "particles" such as pollutants and suspended particulate matters in water bodies. The tracing accuracy and reliability of this system are highly dependent on the real-time, continuous and accurate collection of hydrological parameters — such as flow velocity, flow rate, water level, water temperature, turbidity and other parameters. These data are the key foundation for constructing particle migration mathematical models and correcting simulation errors. Therefore, the micro-hydrological sensor array used for parameter collection has become the core hardware support for the practical application of particle tracking and tracing systems.

[0003] At present, although the micro-hydrological sensor array matched with the particle tracking and tracing system has realized the multi-parameter synchronous collection function, in practical application, limited by the particularity of hydrological monitoring scenarios (such as remote river channels, underground water bodies, long-term unattended areas, etc.), there are significant technical bottlenecks in low-power operation and stable parameter collection even though the array can provide comprehensive, accurate and real-time hydrological data, which seriously restricts the application scope and monitoring efficiency of the system.

[0004] In the prior art, through long-term use and observation, it has been found that biological attachment may occur when the existing micro-hydrological sensor array of the particle tracking and tracing system is in use. After many organisms attach to the surface of the sensor, they will change the original shape and structure of the sensor, causing the flow field of the surrounding water flow to change, which no longer conforms to the ideal water flow state on which the sensor relies for normal measurement, thereby leading to deviation in the flow velocity measurement result and failing to accurately reflect the real water flow velocity. Meanwhile, water flow velocity is an extremely key basic parameter in particle tracking and tracing, and this deviation will affect the subsequent calculation of particle motion trajectory, thereby reducing the reliability of measurement data. Therefore, the micro-hydrological sensor array for the particle tracking and tracing system is provided to address the above problems. Contents of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art, the utility model provides a micro-hydrological sensor array for a particle tracking and tracing system.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The micro hydrological sensor array of the particle tracking and tracing system of this utility model includes a sensor module body; a bracket is symmetrically fixed to the side wall of the sensor module body; a support rod is symmetrically fixed to the side wall of the bracket; a small motor is fixed to the side wall of the support rod; a rotating shaft is fixed to the output end of the small motor; the rotating shaft passes through the surface of the bracket; the connection between the rotating shaft and the bracket is a rotatable connection; a support block is fixed to the end of the rotating shaft; a connecting plate is provided at the bottom end of the support block; and multiple sets of cleaning brushes are provided at the bottom end of the connecting plate.

[0007] The beneficial effects of this utility model are: This utility model provides a micro-hydrological sensor array for a particle tracing and source tracking system. The combination of a bracket, support rod, and small motor provides a stable drive for the cleaning structure. The rotating shaft drives the cleaning brush to rotate, realizing automated cleaning of the sensor, reducing manual maintenance costs. The rotating design of the cleaning brush can fully cover the sensor surface and surrounding area, avoiding the adhesion of impurities and affecting the monitoring accuracy, thus ensuring the accuracy of micro-hydrological data acquisition in the particle tracing and source tracking system.

The output of the small motor 12 drives the rotating shaft 13 to rotate around the bracket 10. The support block 14 at the end of the rotating shaft 13 drives the connecting plate 15 and the cleaning brush 16 to rotate synchronously, realizing mechanical cleaning of the sensor surface. The small motor 12 is an N20 type DC geared motor with a voltage of 3.7V, a speed of 1000rpm, and a torque of 0.5kg·cm. The speed is adjusted by a PWM signal.

The rotating design can fully cover the sensor surface and surrounding area, avoiding the adhesion of impurities that may affect monitoring accuracy and ensuring the accuracy of micro-hydrological data acquisition in the particle tracking and tracing system.

[0014] As shown in Figures 1 to 5, multiple sets of connecting blocks 2 are symmetrically fixed to the side wall of the rotating shaft 13; blades 21 are fixed to the side wall of the connecting blocks 2; multiple sets of mounting plates 22 are fixed to the side wall of the sensor module body 1; connecting ropes 23 are fixed to the side wall of the mounting plates 22; and bouncing balls 24 are fixed to the ends of the connecting ropes 23. During operation, the connecting blocks 2 on the side wall of the rotating shaft 13 fix the blades 21. When the rotating shaft 13 rotates, the blades 21 increase airflow, causing the connecting ropes 23 to vibrate.

The impact force generated by the vibration of the bouncing balls 24 assists in removing stubborn deposits, forming a combined cleaning mode of brushing and vibration. The blades 21 are made of ABS plastic, 2mm thick, and consist of four pieces arranged symmetrically at 90°. They are supported by the mounting plates 22. This design allows the blades 21 and bouncing balls 24 to... The linkage structure uses impact vibration to assist cleaning, which makes up for the inadequacy of simple brushing in removing stubborn impurities and improves the cleaning effect.

[0015] As shown in Figures 1 to 5, the bottom end of the support block 14 is provided with a positioning groove 3; a first magnetic block 31 is fixedly connected to the side wall of the positioning groove 3; a second magnetic block 32 is fixedly connected to the top end of the connecting plate 15; the connection between the second magnetic block 32 and the first magnetic block 31 is a magnetic connection; during operation, the first magnetic block 31 in the positioning groove 3 of the support block 14 and the second magnetic block 32 at the top end of the connecting plate 15 achieve rapid positioning through opposite polarity adsorption. The first magnetic block 31 and the second magnetic block 32 are neodymium iron boron N35 type, with a diameter of 8mm and a thickness of 3mm, and the surface is nickel-plated for corrosion resistance. Through this design, the magnetic connection between the first magnetic block 31 and the second magnetic block 32 enables the quick loading and unloading of the connecting plate 15 and the support block 14, which facilitates the replacement and maintenance of the cleaning brush 16 and shortens the equipment downtime.

[0016] As shown in Figures 1 to 5, the bottom end of the support block 14 has multiple sets of slots 4; the side wall of the connecting plate 15 is fixed with multiple sets of blocks 41; the connection between the blocks 41 and the slots 4 is a snap-fit; during operation, the slots 4 at the bottom end of the support block 14 and the blocks 41 on the side wall of the connecting plate 15 engage in a snap-fit, further enhancing the stability of the connection between the two and preventing the cleaning brush 16 from shifting due to vibration during operation.

[0017] As shown in Figures 1 to 5, the sidewall of the bouncing ball 24 is provided with a rubber pad 5. The rubber pad 5 is connected to the bouncing ball 24 by adhesive bonding.

[0018] As shown in Figures 1 to 5, the surface of the cleaning brush 16 is provided with an electrostatic coating 6. During operation, the electrostatic coating 6 on the surface of the cleaning brush 16 can efficiently adsorb tiny particulate impurities through electrostatic adsorption, thereby improving the cleaning effect of the cleaning brush 16 on the environment surrounding the sensor. Through this design, the electrostatic coating 6 captures tiny particles such as suspended particulate matter and microorganisms through electrostatic adsorption, which makes up for the insufficient ability of mechanical brushing to remove fine impurities, improves cleaning efficiency, reduces secondary pollution from impurities, ensures the cleanliness of the sensor surface, improves the accuracy and stability of micro-hydrological data acquisition, and provides reliable data support for particle tracking and tracing.

[0019] Working principle: The sensor module body 1 forms a support base through the bracket 10 symmetrically fixed to the side wall, and the support rod 11 on the bracket 10 fixes the small motor 12.

The small motor 12 is an N20 type DC geared motor with a voltage of 3.7V, a speed of 1000rpm, and a torque of 0.5kg·cm. The speed is adjusted by PWM signal. The rotating shaft 13 is made of 304 stainless steel, with a diameter of 5mm and a length of 80mm. The connection with the bracket 10 is equipped with a fluororubber sealing ring of model AS568-010 for waterproofing. The cleaning brush 16 uses PA66 nylon bristles. The connecting block 2 on the side wall of the rotating shaft 13 fixes the blades 21. When the rotating shaft 13 rotates, the blades 21 increase the airflow, which blows the connecting rope 23 to shake. The shaking of the connecting rope 23 causes the suspended bouncing ball 24 to strike the sensor module body 1. The impact force generated by vibration assists in removing stubborn deposits, forming a combined cleaning mode of brushing and vibration. The blades 21 are made of ABS plastic, 2mm thick, and consist of four pieces arranged symmetrically at 90°. They are supported by the mounting plate 22. The first magnetic block 31 in the positioning groove 3 of the support block 14 and the second magnetic block 32 at the top of the connecting plate 15 achieve rapid positioning through opposite polarity adsorption. The first magnetic block 31 and the second magnetic block 32 are neodymium iron boron N35 type, 8mm in diameter and 3mm thick, with a nickel-plated surface for corrosion resistance. The slot 4 at the bottom of the support block 14 and the locking block 41 on the side wall of the connecting plate 15 engage through a locking mechanism, further enhancing the stability of the connection and preventing the cleaning brush 16 from shifting due to vibration during operation. The rubber pad 5 bonded to the side wall of the ball 24 reduces the impact force when the blades 21 contact the ball 24, reducing component wear and noise, while enhancing the impact vibration effect to improve cleaning efficiency. The electrostatic coating 6 on the surface of the cleaning brush 16... Through electrostatic adsorption, it can efficiently adsorb tiny particulate impurities, improving the cleaning effect of the cleaning brush 16 on the environment around the sensor.
