Device for controlling inside and outside temperature difference of mass concrete for water delivery gallery

The invention discloses a device for controlling the inside and outside temperature difference of mass concrete for a water delivery gallery, and relates to the field of water conservancy and hydropower construction. Identical-structure core and outside temperatures are controlled to be constant through cooling water circulation and cracking factors are reduced so as to solve the technical problemthat temperature cracking of the mass concrete cannot be avoided effectively in the prior art. Circulating water enters a concrete core through a water supply system, a water sprinkling device at thetail end of a system is arranged at the top of a cavity of the water delivery gallery, a heat dissipation system is arranged below, and sealing systems are arranged at two ends of the water deliverygallery; temperature monitoring systems are embedded in the concrete core and the outside, a warning system which can buzz is arranged, and the whole device can sent messages to a mobile phone application (APP) through an infor
