Multifunctional protection cover of vacuum glass heat collection tube of solar water heater

Abstract

The invention discloses a multifunctional protection cover of a vacuum glass heat collection tube of a solar water heater. The multifunctional protection cover comprises a bracket and the vacuum glass heat collection tube, wherein a motor, a chain wheel I, a chain wheel II and a protection cover are arranged on the bracket; the motor is arranged at the top of the bracket; the chain wheel II is arranged at the bottom end of the bracket; the chain wheel I and the motor are coaxially mounted; a chain is arranged between the chain wheel I and the chain wheel II, and comprises a chain plate and chain pins; the protection cover comprises butterfly style buckles and wire pins; series connection holes are formed in the butterfly style buckles; the wire pins penetrate through the series connection holes in the butterfly style buckles to connect butterfly style buckles in series to form the protection cover; the end parts of the wire pins are coaxially and fixedly connected with the chain pins of the chain; a tin foil layer is arranged on one surface of each butterfly style buckle; in an environment where fireworks and crackers are set off, the protection cover covers the vacuum glass heat collection tube to prevent the vacuum glass heat collection tube from being damaged; and when the protection cover moves with the chain to the location below the vacuum glass heat collection tube, the sunshine reflected by the tin foil layers irradiates the vacuum glass heat collection tube in the shade, so that the efficiency of converting the sunshine into heat is improved.
