[0002] A solar water heater is a heating device that converts sunlight energy into thermal energy, heating water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural form, with vacuum tube solar water heaters being the main ones. Vacuum tube household solar water heaters are composed of related parts such as heat collecting tubes, water storage tanks and brackets. The conversion of solar energy into thermal energy mainly relies on vacuum collecting tubes. Vacuum collecting tubes use the principle that hot water floats and cold water sinks to create a microcirculation of water to obtain the required hot water.

[0003] Since most of the current solar water heaters are composed of a water tank, when many people take turns to use the water for bathing in winter, the water in the tank will not be enough, resulting in people who have not washed yet being unable to bathe. In addition, the hot water pipes of some solar water heaters are connected to the kitchen water supply, which will also cause the kitchen to be unable to use hot water. Utility Model Content

[0037] When the present invention is in use, a general solar water heater is to install a water tank on a bracket 1, and then connect the heat collecting pipe 3 to the water tank to heat the water in the water tank. Since the existing solar water heater has only one water tank, when more people use it together or take turns to use hot water, the water in the solar water heater will be used up quickly. When hot water is needed for work again, there will be no hot water to use, which brings inconvenience to the user. Therefore, a second water tank 401 is installed on the first water tank 2, and the first water tank 2 and the second water tank 401 are connected by a connecting pipe 403, and then the water inlet pipe 402 is connected to the second water tank 401, thereby increasing the water storage capacity of the solar water heater. At the same time, a protective cover 404 is installed at the connecting pipe 403, one of which is a protective cover. 404 is provided with a first clamping block 405, which is made of rubber and can be engaged with a groove provided on another protective sleeve 404, thereby fixing the protective sleeve 404 on the connecting pipe 403. The protective sleeve 404 is provided with a heat-insulating layer 406, which can protect the connecting pipe 403 and prevent the loss of temperature. Since the solar water heaters are installed on the roof, sometimes birds will land near the solar water heaters and peck at the heat collecting pipe 3, which may cause the heat collecting pipe 3 to rupture. Therefore, a bird-repelling belt 509 can be tied to drive away the birds. First, the second clamping block 512 is placed parallel to the bracket 1 so that the opening direction of the second clamping block 512 faces the direction of the first water tank 2, and the plug 502 is plugged into the bracket 1, and then clockwise. When the cam 504 is in the state of rotation, the spring 604 will move the second retaining block 601 and the second retaining block 602, thereby preventing the cam 504 from rotating. The slide bar 505 is fixed, and the clamping block 507 is pressed at this time. The clamping block 507 rotates on the first fixed shaft 506 and generates a torsion force on the torsion spring 508, and a first interference block 510 is installed on the clamping block 507, and a second interference block 511 is installed on the slide bar 505. Then the bird-repelling belt 509 is placed between the first interference block 510 and the second interference block 511, and the clamping block 507 is released. Under the action of the torsion spring 508, the clamping block 507 is driven to rotate to clamp the bird-repelling belt 509. The engagement of the first interference block 510 and the second interference block 511 can clamp the bird-repelling belt 509 more tightly to prevent sliding, thereby driving the birds away. When it is not necessary to drive the birds away, it is only necessary to rotate the fixed block 501 counterclockwise.Make the second clamping block 512 parallel to the bracket 1, and then pull the fixing block 501 away from the bracket 1 to remove the fixing block 501. The operation is simple and convenient.
