A protective device for outdoor led billboards

Abstract

The invention discloses a protection device applied to an outdoor LED advertising board. The protection device comprises a shell, a base plate, the advertising board and a limiting plate, wherein sideplates are connected to four sides of the bottom of the shell; the base plate, which is horizontally arranged, is connected to the bottom of the shell; the advertising board is horizontally arrangedat the bottom of the base plate; and a water tank is welded at the side, close to the shell, of the limiting plate. Three groups of fans are arranged at the top of the shell in a length direction; a plurality of spiral cooling pipes are connected to the side, close to the advertising board, of the connecting plate; reflux pipes and conveying pipes are connected to two ends of the cooling pipes; the conveying pipes and the cooling pipes are connected to the water tank; three groups of rotating shafts are uniformly arranged in the shell in a width direction; and four groups of transverse platesare uniformly welded outside the rotating shaft in a radial direction. Cooling water, in a conveying process, undergoes heat dissipation via a transverse plate and a fan, so that by controlling the temperature of the cooling water to be not too high, good heat-absorbing capacity can be guaranteed, and heat energy can be absorbed in a circulating flowing mode.
