Problems solved by technology

[0002] Solar water heaters rely on heat collecting tubes to convert solar energy into heat to heat water. The vacuum heat collecting tubes of solar water heaters are made of glass. The transmission coefficient of glass is affected by material, thickness, number of layers, incident angle and surface cleanliness. Solar water heaters are placed outdoors all the year round, so there will be dust and other accumulations on the heat collecting tubes, which will prevent sunlight from directly hitting the heat collecting tubes and affect the heat conversion efficiency of the water heater. Therefore, the heat collecting tubes need to be cleaned regularly to maintain a good heating effect
[0003] Existing equipment for cleaning heat collecting tubes often needs to consume a large amount of water resources to flush the heat collecting tubes, and cannot recycle the water used for cleaning, resulting in a lot of waste of resources

Embodiment 1

[0027] Such as Figure 4-13 As shown, a device for cleaning heat collecting pipes of water heaters includes a casing 1, a cleaning device and a fixing tank 10; a water storage chamber 11 is opened in the casing, so that the water in the water storage chamber can be used to repeatedly clean the heat collecting pipes. Clean up, so that water resources can be used repeatedly, avoid waste, and play the role of energy saving and environmental protection; a water inlet pipe 12 and a water outlet pipe 13 are installed on the shell, which is convenient for filling water into the water storage chamber and draining the waste water in the water storage chamber. It is more convenient to use; the fixing groove 10 is set in the middle of the upper surface of the shell, and a first arc surface 101 is set on the upper edge of the fixing groove, so that the heat collecting tube is easy to be embedded in the fixing groove and fixed, and the cleaning device is convenient. Cleaning of the heat co...

Embodiment 2

[0039] Such as Figure 1-3 As shown, the difference between this embodiment and Embodiment 1 is that a filter device is installed, which includes a drainage ring 41, a flow guide channel 42 and a filter basket 43; the outer wall of the fixing groove 10 first extends outwards and then downwards Surrounding the sewage outlet 103, a drainage ring is formed, and the sewage in the fixed tank will be discharged into the drainage ring through the sewage outlet; an opening is opened on the drainage ring, and one end of the diversion channel is connected to the opening The other end of the diversion channel is connected with the filter basket, so that the sewage in the drainage ring can flow into the filter basket through the diversion channel; multiple limit rods 44 are installed in the shell, and the filter basket is installed on the limit rod Between them, it is fixed in the shell by the limit rod; a cover plate 45 is installed on the shell above the filter basket, and the cover pla...

Abstract

The invention discloses novel equipment for heat collection tube cleaning of a water heater. The novel equipment comprises a casing and a cleaning device arranged on the casing. The casing comprises a fixing groove, a first curved surface arranged on the fixing groove, a convex edge arranged in the fixing groove and sewage outlets formed in the convex edge. A filtering device for collecting dirt is arranged in the casing. The filtering device comprises a drainage loop which cooperates with the sewage outlets, a guiding channel communicated with the drainage loop and a filter basket communicated with the guiding channel. According to the novel equipment, through the cooperation arrangement of the drainage loop, the guiding channel and the filtering basket, the water resources can be recycled, the waste of resources is greatly reduced, and he role of energy conservation and environmental protection is played; and meanwhile the cleaning effect is good, and the cleaner effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a device for cleaning heat collecting tubes of water heaters. Background technique [0002] Solar water heaters convert solar energy into thermal energy to heat water by heat collecting tubes. The vacuum heat collecting tubes of solar water heaters are made of glass. The transmission coefficient of glass is affected by material, thickness, number of layers, incident angle and surface cleanliness. Solar water heaters are placed outdoors all year round, so there will be dust and other accumulations on the heat collecting tubes, which will prevent sunlight from directly hitting the heat collecting tubes and affect the heat conversion efficiency of the water heater. Therefore, the heat collecting tubes need to be cleaned regularly to maintain a good heating effect. [0003] Existing equipment for cleaning heat collecting tubes often needs to consume a large amount of...
