[0002] Currently, there is no known device on the market for cleaning water accumulated in the insulation foam panels inside large-span roofs, given the existing state of maintenance for thermal insulation materials. This problem presents several hazards.

[0003] (1) Water accumulation in the insulation foam board inside the large-span roof leads to seepage, causing water dripping and seepage from the ceiling during rainy weather.

[0004] (2) Water accumulation increases the load on large-span roofs, which can easily lead to accidents such as partial roof collapse that endanger the safety of the building.

[0005] (3) The existing roof cannot effectively clean up water accumulation on its own, and once water accumulation occurs in the roof insulation sponge board inside the roof, it cannot be resolved in a timely manner. Summary of the Invention

[0025] Specifically, the installation area height between the perforated hot air duct layer and the second perforated hot air duct layer is 15cm.

[0026] The efficiency of water evaporation in the insulation sponge board is improved by setting a second perforated hot air duct layer.

It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0040] Figure 1 This is a schematic diagram of the vertical structure of a device for evaporating and cleaning water accumulation on a heat-insulating sponge board using a hot air duct, according to an embodiment of this application. Figure 1 As shown, this application provides a device for evaporating and cleaning water accumulation on a thermal insulation sponge board using a hot air duct, characterized in that it includes: a device for evaporating and cleaning water accumulation on a thermal insulation sponge layer using a hot air duct, comprising:

[0041] The mounting base 6 is used for installation inside the roof and serves as a support.

[0042] A perforated hot air duct layer is used to be installed on the mounting base 6. One end of the perforated hot air duct layer is connected to a perforated hot air outlet and the other end is connected to an air pump 7.

[0043] Insulating sponge layer for installation above perforated hot air duct layer;

[0044] Sensor 10 is used for installation at a perforated hot air outlet.

[0045] When sensor 10 detects that the humidity in the insulation sponge layer reaches the preset humidity, the host computer controls the perforated hot air duct layer and air pump 7 to work, so that the water accumulated in the insulation sponge layer evaporates and is discharged from the perforated hot air outlet; and when sensor 10 detects that the humidity in the insulation sponge layer is lower than the preset humidity or the temperature reaches the preset temperature, the host computer controls the perforated hot air duct layer and air pump 7 to stop working.

[0046] Specifically, the heat insulation sponge layer includes multiple heat insulation sponge boards 1, which are arranged in parallel with a certain gap between each pair of heat insulation sponge boards 1.

[0047] In addition, in humid climates, a second perforated hot air duct layer 4 can be installed above the insulation sponge layer; the second perforated hot air layer includes: a duct shell 11, a support rod 13, and a heating pipe 12; the inner diameter of the perforated hot air duct is 15cm; the inner diameter of the heating pipe 12 is 7cm; the support rod 13 is located between the duct shell 11 and the heating pipe 12 to support the heating pipe 12; the surface of the duct shell 11 has multiple evenly arranged round holes; one end of the second perforated hot air duct layer 4 is connected to the second perforated hot air outlet 2 and the other end is connected to the air pump 7.

[0048] Meanwhile, the heating pipe 12 is used to evaporate the water accumulated in the roof insulation sponge board 1 inside the large-span roof. The temperature of the heating pipe 12 is fixed at 100℃. The sensor 10 monitors the humidity and temperature of the area where the heating pipe 12 is installed in real time through wireless software control. When the temperature is too high (reaching 105℃) or the humidity is lower than the set value (adjusted according to local climate conditions), the wireless signal is transmitted to the control console to stop the perforated hot air duct from working.

[0050] Figure 7 This is a schematic diagram of a humidity-sensitive capacitor in a device for evaporating and cleaning water accumulation on a heat-insulating sponge board according to an embodiment of this application. Figure 7 As shown, the sensor is a humidity-sensitive capacitor. Humidity-sensitive capacitors are generally made of polymer film capacitors, with common polymer materials including polystyrene, polyimide, and cellulose acetate. When the ambient humidity changes, the dielectric constant of the humidity-sensitive capacitor changes, causing its capacitance to change as well; the change in capacitance is proportional to the relative humidity. The main advantages of humidity-sensitive capacitors are high sensitivity, good product interchangeability, fast response speed, low humidity hysteresis, ease of manufacturing, and ease of miniaturization and integration. Their accuracy is generally lower than that of humidity-sensitive resistors. Taking the Humirel SH1100 humidity-sensitive capacitor as an example, its measurement range is (1%–99%) RH, and its capacitance at 55% RH is 180 pF (typical value). When the relative humidity changes from 0 to 100%, the capacitance changes from 163 pF to 202 pF. The temperature coefficient is 0.04 pF / ℃, the humidity hysteresis is ±1.5%, and the response time is 5 seconds.
