4results about How to "Realize cleaning work" patented technology

The present application relates to the technical field of photovoltaic equipment, and particularly relates to a photovoltaic module waterless cleaning device and system thereof, which comprises a mounting plate frame and photovoltaic panels uniformly mounted on the top of the mounting plate frame, and further comprises a waterless cleaning device arranged on the mounting plate frame, wherein the waterless cleaning device comprises: a smart driving assembly comprising a mounting frame, a controller, a double-shaft motor and a reciprocating conveying mechanism; and a waterless cleaning assembly comprising a mounting roller, a dust thickness detection mechanism, a pressurized air blowing mechanism, a hot spot detection mechanism and a marking mechanism. The present application has a reasonable structure, and the waterless cleaning device is ingeniously driven by the self-generated power of the photovoltaic panels. Through the advanced pressurized air blowing technology, the traditional mechanical water washing and manual wiping methods are efficiently and safely replaced, and the waterless and efficient cleaning of the photovoltaic module is realized. This design not only significantly improves the power generation efficiency of the photovoltaic power station, effectively prolongs the service life of the photovoltaic module, but also greatly reduces the cost and time input of the cleaning operation.

This utility model discloses a polyester film extrusion die with a cleaning structure, belonging to the field of plastic processing machinery. Addressing the problem of incomplete cleaning of residues on the inner wall of existing die exits, the following solution is provided: The die body features a gradient cavity structure, with grooves on the side walls and trapezoidal cross-section scrapers. The bottom end of the scraper is connected to the inner cavity of the main rod via a threaded rod. Rotating the threaded rod adjusts the scraper position to ensure a tight fit against the gradient inner wall. A sliding seat and sliding frame are installed on the outer wall of the main rod to achieve lateral movement. An external protective sleeve covers the operating side hole, and the sleeve is connected to the sliding seat via a tension spring. A sealing plate with a compression spring is installed at the top of the inner cavity; the sealing plate remains in contact with the scraper during movement to prevent foreign objects from entering. This device, through scraper shape adaptation and position adjustment mechanisms, more effectively cleans residues from the inner wall. The protective sleeve structure prevents accidental contact with operating parts, ensuring the reliability and convenience of cleaning operations.

The utility model discloses an auxiliary box closing mechanism of a swage sand-coated molding machine, which relates to the technical field of sand-coated molding and comprises a lower shell, an equipment support is fixedly mounted on the lower shell, an upper shell is fixedly mounted at the upper end of the equipment support, and a box closing mechanism is arranged between the upper shell and the lower shell. The box closing mechanism comprises a lower sand box fixedly mounted on the lower shell and an oil cylinder fixedly mounted in the upper shell, an upper sand box is fixedly mounted at the lower end of the oil cylinder, a cleaning mechanism is arranged above the lower sand box, a guide rod is fixedly mounted between the upper shell and the lower shell, a lifting seat is slidably mounted on the guide rod, and the lifting seat is fixedly mounted at the output tail end of the oil cylinder; a mounting base is arranged at the bottom of the lower sand box; a driving rod is fixedly mounted on the lower surface of the lifting seat. According to the auxiliary mold closing mechanism of the iron mold sand-coated molding machine, the mold closing mechanism and the cleaning mechanism are matched for use, so that the upper end of the lower sand box can be cleaned before mold closing, and the air tightness after mold closing is ensured.

The utility model belongs to the technical field of windows, and particularly relates to a frame sash structure of an inward side-hung door and window, which comprises a window frame, a placing groove is arranged inside one side of the bottom end of the window frame, a sliding groove is arranged inside the edge of one side of the window frame, a transverse groove is arranged inside the window frame and vertically penetrates through the sliding groove, and a connecting rod is arranged inside the transverse groove in a sliding and penetrating mode. A rolling ball is arranged in the middle of the connecting rod, a supporting rod is installed on the bottom side of the rolling ball, and a cleaning brush is installed at the bottom end of the supporting rod. The handle drives the connecting rod and the rolling ball to rotate in the transverse groove and the sliding grooves correspondingly, then the supporting rod is driven to rotate, then the handle is pushed to move up and down, the connecting rod slides in the transverse groove, the rolling ball moves in the sliding grooves, and the connecting rod drives the cleaning brush to move up and down on one side of the window along the sliding grooves. And after cleaning is completed, the cleaning brush is moved to the bottom end of the window frame, the handle is rotated reversely, the supporting rod is made to return to the state parallel to the window frame, and the cleaning brush is placed back into the containing groove.
