Problems solved by technology

Ordinary solar water heaters are fixed on the roof of general buildings at a certain angle. Since the water storage tank of the solar water heater is exposed outdoors, the water pipes from the outlet of the water tank to the roof are prone to freezing in winter, which affects the use of hot water by users. Seriously, the water pipes will be frozen and cracked, wasting a lot of water. Therefore, to prevent the pipes from freezing and to make the water heater flow normally, usually wrap the pipes with an insulation layer or add an electric heating device, but the former method cannot effectively prevent the pipes from being damaged. The latter consumes power and is not energy-saving; and the water tank is used for a long time, and the dirt inside it will easily block the water pipe, causing the water in the water tank to be unable to discharge

Embodiment 1

[0035] Such as Figure 1 to Figure 7 As shown, a winter antifreeze device for a solar water heater of the present invention includes a water storage tank 4, the bottom of the water storage tank 4 is provided with a water guide pipe 1, and the top of the water guide pipe 1 is flush with the bottom end of the water storage tank 4, and the water storage tank 4 is flush with the bottom of the water storage tank 4. The inner top wall of the water tank 4 is also provided with a fixed pipe 8, the axis of the fixed pipe 8 is on the same straight line as the axis of the aqueduct 1, one end of the fixed pipe 8 is fixed with the inner top wall of the water storage tank 4, and the other end is The first corrugated pipe 6 is arranged on the top, and the first corrugated pipe 6 can expand and contract along the axial direction of the water guide pipe 1. The outer peripheral wall of the fixed pipe 7 is also provided with a number of air holes 7 communicating with the inside. One end of the f...

Embodiment 2

[0037] On the basis of Embodiment 1, both sides of the connector 5 are provided with limiting grooves 18, and both sides of the inner wall of the aqueduct 1 are provided with first grooves, and the first grooves are provided with The third elastic member 20 is provided with a limiting ball 22 matching the limiting groove 18 on the third elastic member 20 , and the limiting ball 22 can be inserted into the limiting groove 18 .

Embodiment 3

[0039] On the basis of Embodiment 2, a second cavity 19 is also provided in the connector 5, and push rods 17 are arranged on both sides of the inner wall of the second cavity 19, and one end of the push rod 17 extends into the second cavity. In the second cavity 19, the other end is located in the limit groove 18. The movable rod 15 of conical structure is also provided in the second cavity 19. The diameter of the movable rod 15 gradually decreases along the direction of the push rod 17, and the movable rod 15 is movable. The maximum diameter of the rod 15 is consistent with the inner diameter of the cavity 19 , the movable rod 15 can move toward the direction of the push rod 17 , and push the push rod 17 to protrude from the limiting groove 18 .

Abstract

The invention discloses a solar water heater winter anti-freezing device. The solar water heater winter anti-freezing device comprises a water storage tank, a bottom part of the water storage tank isprovided with a water guiding pipe, an inner top wall of the water storage tank is provided with a fixed pipe, a first corrugated pipe is arranged on the fixed pipe, the fixed pipe is also provided with an air hole, the first corrugated pipe is provided with a connector, the connector can be connected with the water guiding pipe, a first cavity is arranged in the connector, the first cavity is communicated with the first corrugated pipe, a tail end face of the connector is provided with a guide rod and a through hole, the guide rod moves and connects to the connector, the other end stretches into the water guiding pipe, a fixing plate is also arranged in the water guiding pipe, the fixing plate is provided with a leakage hole, a first elastic piece is arranged between the fixing plate andthe connector, and a second corrugated pipe is arranged in the first corrugated pipe. The solar water heater winter anti-freezing device can completely evacuate water in the water guiding pipe after awater heater is used, avoids freezing crack of the water guiding pipe, meanwhile can cleaning dirt in the water storage tank, and avoids blocking of the water guiding pipe for water discharge causedby the dirt.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a winter antifreeze device for solar water heaters. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. Solar water heaters are composed of vacuum heat collecting tubes, stainless steel water tanks and brackets. They are a major industry in the application of solar energy achievements. C...
