Market planning propaganda publicity board cleaning device based on electromagnetic principle effect

Abstract

The invention relates to the technical field of market planning, and discloses a market planning propaganda publicity board cleaning device based on an electromagnetic principle effect. The device comprises a panel, airbags are fixedly mounted at the left end and the right end of the panel, magnetic wheels are rotatably connected to the front ends of the airbags, cleaning rods are fixedly mountedon the magnetic wheels, and a fixed pipe is fixed in the panel. According to the device, a driving rod is controlled to be started, the driving rod drives a rotating screw to rotate, the rotating screw drives a gear to rotate, and the gear drives the rotating rod to get close to the end faces of the airbags on the two sides and then enter a magnetic field provided by a permanent magnet, and a conductive wire wound around the rotating rod is matched to do magnetic induction line cutting motion in the magnetic field, so that the intensity of the magnetic field generated on the conductive wire becomes stronger and stronger, the magnetic wheels can be affected, the magnetic wheels are driven to deviate and rotate, the magnetic wheels rotate to drive the cleaning rods to move, and thus the effect of automatically cleaning the panel is achieved.

Description

technical field [0001] The invention relates to the technical field of market planning, in particular to a cleaning device for market planning publicity bulletin boards based on electromagnetic principles. Background technique [0002] Market planning is a professional who engages in applying scientific thinking and methods to systematically plan the overall activities of social and economic organizations for profit in order to achieve the best results; the main daily work of market planners includes: planning target positioning, planning diagnosis Investigation, etc., in the process of market planning and implementation, bulletin boards are generally required. [0003] When the existing publicity bulletin boards for market planning are used, they are generally placed on the side of the road or where people pass by. Although they can be seen by more people, they will also be contaminated with a lot of dust and need to be cleaned regularly by staff. The publicity board is re...
