Description

Curtain-type solar water heater water-saving dual-purpose temperature control device

Technical field:

The utility model belongs to the technical field of manufacturing and processing of solar water heaters, in particular to a water-saving dual-purpose temperature control device for solar water heaters.

Background technique:

As far as the inventor knows, none of the solar water heaters produced and sold on the market are equipped with a temperature control device to raise the water temperature of the water tank to the boiling point. In summer, the light is long and the light is strong, and the outdoor temperature is very high. It depends on the strength of the sunshine. In summer, the temperature is very high. The water in the water tank evaporates until the water in the collector tube is empty. Because of the high temperature of the water tank, fresh water is evaporated, resulting in multiple reactive water additions. As far as the country is concerned, the water temperature of solar water heaters rises in summer. The waste of fresh water evaporated is astonishing, which is not in line with the purpose of a conservation-oriented society proposed by the central government.

Invention content:

The purpose of this utility model is to overcome the above defects and provide a water-saving dual-purpose temperature control device for solar water heaters that can regulate the excessive temperature of solar water heaters in summer, avoid equipment bursting, and save water.

The utility model is achieved in this way, the curtain type solar water heater water-saving dual-purpose temperature control device structural design is made up of shading curtain (1), ventilation hole (2), upper support roller (3), lower support roller (4) , lower tension rod (5), upper tension rod (6), fixed pulley (7), base plate (15), water tank (13), heat collector (9), it is characterized in that An upper tension rod (6) is horizontally arranged, a lower tension rod (5) is horizontally arranged at the lower end of the support (14), and a shading piece is arranged between the upper tension rod (6) and the lower tension rod (5) The curtain (1) is provided with a ventilation hole (2) on the blackout curtain (1), a lower support roller (4) is arranged horizontally at the bottom end of the support (14), and an upper support roller (4) is horizontally provided at the bottom upper end of the support (14). The roller (3), the weight (8) is connected with the pulley (5) through the fixed pulley (7) with a thin wire rope, and the handwheel (11) or the electric controller (12) is connected with the upper pulley through the steel wire (10). Tight stick (6). Its working principle is that in the initial state, due to the action of the heavy hammer (8), the blackout curtain (1) is placed under the heat collector (9) through the pulley (7) and the steel wire rope to tighten the tension rod (5). Close to the high end of the heat collector (9), while the upper tension rod (6) is placed under the heat collector (9), and the upper end of the shading curtain (1) is all close to the bottom of the heat collector (9), shading The curtain (1) acts as a reflector, and when the temperature rises above a predetermined value, the operating handwheel (11) or the electric controller (12) pulls the upper tension rod (6) through the steel wire (10) to make the blackout curtain (1) Displacement, gradually cover the sunlight, reduce the light-receiving area of the heat collector (9), and the temperature of the water tank (13) no longer rises, which plays the role of saving water and cooling down. On the contrary, when the water temperature is not high, reverse rotation The hand wheel (11) or the electric controller (12) makes the blackout curtain (1) reflectively through a series of actions due to the action of the weight, increases the light-receiving area of the heat collector, and makes the water temperature of the heat collector rise continuously until it reaches the predetermined value .

The water-saving dual-purpose temperature control device of the solar water heater of the utility model has the advantages of being able to adjust the high temperature of the solar water heater in summer, avoiding equipment bursting, saving a large amount of water, compact structure, elegant appearance, safe and reliable, practical and flexible, and good quality.
