Description

Technical Field

[0001] The utility model belongs to the technical field of urban and rural water supply protection, in particular to a safety protection device for urban and rural water supply. Background Art

[0002] Urban and rural water supply pipes are pipe networks used to provide urban and rural residents with water for living and production. They are composed of water transmission pipes, water distribution pipes, household pipes, etc. They are the core facilities of urban water supply and undertake the important task of ensuring the lives of urban and rural residents and economic development.

[0003] In winter, when urban and rural water supply pipes are supplying water, due to the influence of the weather, when the water is at 0℃ or below 0℃, the water in the pipes freezes rapidly, the volume expands, and the water pressure increases suddenly, causing the tap water pipes to expand locally under pressure limits, eventually leading to cracks, which have a destructive effect on the pipes.

[0004] Currently, when the temperature is low in winter, a common method is to wrap urban and rural water supply pipes with cloth for insulation. However, once the temperature is too low, this insulation method can hardly prevent the inside of the water pipes from freezing and breaking, which seriously affects the convenience of water use and has poor anti-freeze effect.

[0005] For this reason, a safety protection device for urban and rural water supply is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a safety protection device for urban and rural water supply in order to improve the heat preservation and antifreeze effect of urban and rural water supply pipes when used in winter.

[0009] The inner tube mechanism comprises an inner tube, a steam cavity and an antifreeze cavity are provided inside the inner tube, and the antifreeze cavity is filled with antifreeze liquid;

[0010] The antifreeze layer includes a rubber sponge layer, the inner side wall of the rubber sponge layer is fixedly connected to the outer surface of the inner tube, the outer surface of the rubber sponge layer is bonded with a glass wool layer, and the side of the glass wool layer away from the rubber sponge layer is bonded with a polyurethane foam plastic layer.

[0011] Furthermore, a rubber layer is bonded to a side of the outer tube away from the antifreeze layer.

[0012] Furthermore, the internal volume of the steam cavity is connected to a hot steam exhaust pipe.

[0013] Furthermore, the thickness of the rubber-plastic sponge layer is 3cm-5cm.

[0014] Furthermore, the thickness of the glass wool layer is 4cm-6cm.

[0015] Furthermore, the thickness of the polyurethane foam plastic layer is 6cm-7cm.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, in winter, the antifreeze liquid has a relatively low freezing point, which can reach minus 40 degrees to minus 60 degrees, and can provide antifreeze protection for the water inside the inner tube from the outside, with a good antifreeze effect; at the same time, hot steam can be input into the steam cavity, and the steam entering the steam cavity can keep the inner tube and the water inside the inner tube warm to prevent freezing; through the cooperation of the above structures, the insulation and antifreeze effect of urban and rural water supply pipes in winter can be improved.

[0018] 2. In the utility model, the antifreeze layer can provide antifreeze protection for urban and rural water supply pipes from the outside, wherein the rubber and plastic sponge of the rubber and plastic sponge layer is a closed-cell material with low thermal conductivity, which can effectively block the heat on the inner pipe from transferring to the outside, thereby insulating the water in the inner pipe and preventing the inner pipe from freezing; the glass wool of the glass wool layer has excellent thermal insulation and corrosion resistance, and can also effectively insulate the inner pipe and reduce heat loss; the polyurethane foam plastic of the polyurethane foam plastic layer has excellent thermal insulation and low-temperature resistance, which further prevents the transfer and loss of heat in the inner pipe, thereby protecting the inner pipe from freezing; through the cooperation of the above structures, the thermal insulation and antifreeze effect of urban and rural water supply pipes when used in winter can be improved.
