Description

Anti-freezing detection device for fire hydrant and fire water crane

Technical Field

The invention relates to the technical field of fire fighting systems, in particular to an anti-freezing detection device for a fire hydrant and a fire fighting water crane.

Background

The automatic drain valves are arranged at the underground bottoms of the outdoor fire hydrant and the fire water crane, and after the automatic drain valves are used, the automatic drain valves are automatically opened to drain all residual water above the drain valves in the pipeline. Therefore, under the quasi-working state, the upper pipe section of the water release valve in the fire hydrant and the fire water crane well chamber is in the water-free state, and the lower pipe section of the water release valve is in the water flushing state. In order to prevent the occurrence of freezing accidents, the problem that the temperature of a water filling pipe section below a water drain valve is higher than 0 ℃ is firstly solved. There are three ways of heat propagation: thermal conduction, thermal convection, and thermal radiation. For the land, the cold air on the upper layer of the stratum in winter transfers the low temperature to the deep part of the stratum, the medium for transferring is soil, the transferring mode is heat conduction, the heat transferring in the well chamber is obviously different from the above, firstly, the transferring medium is different, the heat transferring medium in the well chamber is air and heat insulating material, and the heat conductivity coefficient of the air is different from that of the soil. Secondly, the heat propagation mode is different, and besides heat conduction, if the well cover is not tightly closed, heat convection exists in the well. Therefore, factors influencing the temperature distribution in the well chamber are obviously more complex than those of the soil layer, both positive factors and negative factors exist, and the judgment standard of the well chamber for preventing freezing is not comprehensive or inaccurate only by taking the depth of the drain valve below the frozen soil layer as the judgment standard.

The anti-freezing detection of the fire hydrant and the fire fighting water crane is difficult to objectively and accurately judge the position of the freezing point in the well chamber only by eye observation and hand touch. At present, no document exists for domestic experts and scholars to analyze and research the temperature freezing point in a fire hydrant and a fire hydrant well, and no equipment for detecting the anti-freezing condition of the well is available in the market.
