Pipeline emptying anti-freezing type solar water heater

Abstract

The invention belongs to the technical field of solar water heaters, and discloses a pipeline emptying anti-freezing type solar water heater. The pipeline emptying anti-freezing type solar water heater comprises a support, wherein a water tank is arranged at the top end of the support; one side of the lower surface wall of the water tank is connected with water outlet pipes at equal intervals through heat collecting pipes; fixing plates are symmetrically fixed to the two ends of the outer surface wall of the water tank; third inserting grooves are formed in the outer surface walls of the fixing plates at equal intervals; a protection assembly is arranged outside the water tank, and comprises a first arc-shaped plate and a second arc-shaped plate; and inserting blocks matched with the thirdinserting grooves are connected to the inner walls of the first arc-shaped plate and the second arc-shaped plate at equal intervals. The protection assembly composed of the first arc-shaped plate, the second arc-shaped plate, a first protection rod and a second protection rod is additionally arranged outside the water tank, when the water tank is collided, the first protection rod and the secondprotection rod blocking the outer portion of the water tank are in contact and impact, the water tank can be effectively prevented from being sunken and damaged, and the service life of the water tankis prolonged.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, and in particular relates to a pipe-empty antifreeze solar water heater. Background technique [0002] Solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. Composition of related spare parts, the conversion of solar energy into heat energy mainly depends on the vacuum outlet pipe. The vacuum outlet pipe uses the principle of hot water floating and cold water sinking to make the water produce microcirculation and obtain the required hot water. With the advancement of technology, the pipe is emptied Technology is more and more applied to solar water heaters, which can solve the problem of freezing water pipelines due to cold weather. [0003] However, the existing antifreeze solar water heaters have certain defects. The water tank of...
