Description

Technical Field

[0001] The utility model relates to the technical field of solar water heater pipe antifreeze, in particular to an outdoor water pipe antifreeze structure of a solar water heater. Background Art

[0002] Solar water heaters are heating devices that convert sunlight into heat energy, heating water from low temperature to high temperature to meet people's needs for hot water 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. Vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. 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 heat energy mainly relies on vacuum collecting tubes. Vacuum collecting tubes use the principle that hot water floats and cold water sinks to make water microcirculate and obtain the required hot water.

[0003] When laying out the solar water heater, it is necessary to leave pipes on the outdoor walls for drainage. At this time, the pipes are directly exposed to the external environment. In winter when the external temperature is low, the outdoor pipes are prone to freezing, which will affect the normal operation of the solar water heater. The most common method is to wrap the outdoor pipes with flexible insulation materials, and then use tape to wrap them at multiple points so that the insulation materials are firmly attached to the outside of the outdoor pipes and fit with the outdoor pipes. This installation process is time-consuming and not convenient enough, and the antifreeze operation process of outdoor pipes needs to be further optimized. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes an outdoor water pipe antifreeze structure of a solar water heater.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A solar water heater outdoor water pipe antifreeze structure comprises a plurality of sets of first shells and second shells for use in combination, the first shells are symmetrically provided with fixing grooves at both ends, insert tubes are arranged in the fixing grooves, a plastic container containing glue is arranged at the tail end of the insert tubes, the second shells are symmetrically provided with insert posts corresponding to the insert tubes one by one and tightly fitting with the inner walls of the insert tubes at both ends, a plurality of spikes are arranged at one end of the insert posts, the spikes cooperate with the plastic container to make the glue in the plastic container flow out so that the first shell and the second shell are efficiently installed and fixed, and the inner walls of the first shell and the second shell are both provided with insulation boards fitting with outdoor pipes.

[0007] Compared with the prior art method of wrapping outdoor pipes with flexible insulation materials and wrapping them with tape at multiple points, this device can greatly shorten the installation time and effectively reduce the probability of outdoor pipes freezing in winter. It is quick to operate and firmly fixed, and the antifreeze operation process of outdoor pipes is further optimized.

[0008] Furthermore, a plurality of installation grooves are arranged on the circumference of the insulation board, and heating elements which fit with the outdoor pipes are arranged in the installation grooves.

[0009] Furthermore, the heating element is a heating plate.

[0010] The above scheme can heat the outdoor pipes through the heating plate, thereby further reducing the probability of the outdoor pipes freezing.

[0011] Furthermore, the heating element is a heating tape.

[0012] The above solution allows the heating tape to directly contact the outer wall of the outdoor pipe, which can also reduce the probability of outdoor pipe freezing. Compared with the winding type, this reduces the installation time and only requires the two shells to be connected.

[0013] Furthermore, the first shell and the second shell are both made of glass fiber.

[0014] In the above scheme, the first shell and the second shell are both made of glass fiber and thus have good corrosion resistance and hardness, and also have a heat-insulating effect and are light in weight. When used in combination with an insulation board, the heat-insulating effect is even better.

[0015] Furthermore, the glue is epoxy resin glue.

[0016] The above scheme adopts epoxy resin glue which solidifies quickly and has high viscosity.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] Compared with the prior art method of wrapping outdoor pipes with flexible insulation materials and wrapping them with tape at multiple points, this device can greatly shorten the installation time and effectively reduce the probability of outdoor pipes freezing in winter. It is quick to operate and firmly fixed, and the antifreeze operation process of outdoor pipes is further optimized. BRIEF DESCRIPTION OF THE DRAWINGS
