Description

Technical Field

[0001] This utility model relates to the field of secondary sedimentation tanks, specifically to a solar-powered automatic cleaning device for secondary sedimentation tanks. Background Technology

[0002] Secondary sedimentation tanks are widely used in wastewater treatment. After biological treatment, wastewater enters the secondary sedimentation tank, where its function is to separate sludge from water, clarify the mixed liquor, concentrate the sludge, and return a portion of the separated sludge to the biological treatment section.

[0003] In most wastewater treatment plants, algae easily grows in the effluent channels of secondary sedimentation tanks, which negatively impacts the overall appearance and effluent quality. Currently, algae removal primarily involves manual cleaning and dredging. This method is not only labor-intensive and time-consuming but also poses safety hazards. Therefore, solving this problem requires the development of an automatic cleaning device that can reduce labor intensity and significantly improve the appearance and operational status of the secondary sedimentation tank effluent channels.

[0004] The automated design of this device reduces the need for manual maintenance and improves work efficiency. Utilizing solar energy as a power source is not only energy-saving and environmentally friendly, but also reduces operating costs. Through this solar-powered automatic brush cleaning device, the effluent tank of the secondary sedimentation tank can be kept clean, thereby ensuring the stable operation of the wastewater treatment system and the quality of the effluent. Against this backdrop, we designed and manufactured a solar-powered automatic brush cleaning device. Therefore, those skilled in the art provide a solar-powered automatic cleaning device for secondary sedimentation tanks to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a solar-powered automatic cleaning device for secondary sedimentation tanks, including fastening devices, transverse roller brushes, longitudinal roller brushes, a drive device, roller brush motors, traveling wheels, a PLC controller, a reciprocating travel trigger, a base plate, and transmission lines. Fastening devices are installed at the four corners of the lower side of the base plate. Transverse roller brushes are installed at the front and rear ends of the lower side of the base plate, and longitudinal roller brushes are installed in the middle of the lower side of the base plate. The transverse and longitudinal roller brushes are connected to the roller brush motors via transmission lines. Traveling wheels are installed on the lower side of the base plate and are connected to the drive device via transmission lines. The drive device, roller brush motor, PLC controller, and reciprocating travel trigger are all connected by transmission lines.

[0006] Preferably, fixing rods are installed at the four corners of the upper side of the base plate, and fixing sleeves can be fitted onto the top of the fixing rods. The fixing sleeves are installed at the bottom of the photovoltaic panel. The photovoltaic panel is connected to the MPPT controller via a transmission line and is connected to the battery via the transmission line.

[0007] Preferably, the base plate has multiple sets of wheel frames and multiple sets of axle frames installed on its underside. The wheel frames are equipped with walking wheels, and the axle frames are equipped with the rotating shaft of the transverse roller brush. The base plate has multiple wire holes through which transmission lines can be inserted.

[0008] Preferably, the photovoltaic panel converts solar radiation into DC power based on the photoelectric effect, which is then stored in a battery after being optimized by an MPPT controller. This system is adapted to the local latitude and sunshine conditions. The energy storage system is equipped with an overcharge / discharge protection circuit to ensure that it can maintain normal operation for 3-5 days even in cloudy or rainy weather.

[0009] Preferably, the PLC controller coordinates the reciprocating travel trigger and drive device to drive the traveling wheels to reciprocate along the track. The movement speed can be dynamically adjusted according to the dirt thickness. The roller brush motor drives the horizontal and vertical roller brushes for cleaning. The roller brush motor speed is adjustable from 200-800rpm. It is equipped with an STM32 series processor and integrates a programmable cleaning strategy (timed / trigger / emergency modes). The system achieves more than 60% energy saving compared to traditional methods through photovoltaic-energy storage-drive-cleaning closed-loop control. With the help of self-diagnostic function, it realizes unattended operation and maintenance.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. The transverse roller brush and longitudinal roller bolt adopt composite fiber bristles combined with frequency conversion control, which automatically adjusts the brushing force according to the thickness of dirt, with a cleaning rate of ≥95% and no damage to the pool wall. Compared with traditional fixed speed brushing, energy consumption is reduced by 30% and cleaning efficiency is increased by 40%.

[0012] 2. The photovoltaic panel adopts a monocrystalline silicon solar panel + MPPT controller, and the low light power generation efficiency is 1.3 times that of polycrystalline silicon in the same scenario. The lithium iron phosphate battery supports operation from -20℃ to 60℃, has a cycle life of more than 2000 times, achieves zero carbon emission power supply, and extends the equipment life to 10 years.

[0013] 3. The STM32 is responsible for real-time data acquisition and algorithm optimization, while the PLC ensures stable industrial-grade control, balancing flexibility and reliability. In high-temperature and humid environments, the system failure rate is reduced to 0.1 times / thousand hours.

[0014] 4. A fastening auxiliary walking device has been added to reduce the cleaning device's movement against the pool wall and avoid the risk of tipping over. A reciprocating trigger device has also been added to enable reciprocating motion. Attached Figure Description
