Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a device and method for cleaning water accumulated in the internal insulation sponge panels of a large-span roof. Background Technology

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

[0003] To achieve the above objectives, this application adopts the following technical solution: The first aspect of this application provides a device for cleaning water accumulated in the internal insulation foam board of a large-span roof, comprising: a first heating layer for installation above a substrate of the internal insulation foam layer; an insulation foam layer for installation above the first heating layer; a second heating layer for installation above the insulation foam layer; a plurality of steam exhaust bends for draining water accumulated in the internal insulation foam board, one end of the steam exhaust bends being connected to the heating layer and the other end extending out of the roof; a sensor for installation at the lower part of the steam exhaust bends; and when the sensor detects that the humidity in the insulation foam layer reaches a preset humidity, the computer controls the first heating layer and the second heating layer to operate, causing the water accumulated in the insulation foam layer to evaporate and be discharged from the steam exhaust bends; and when the sensor detects that the humidity in the insulation foam layer is lower than the preset humidity or the temperature reaches a preset temperature, the computer controls the first heating layer and the second heating layer to stop operating.

[0004] The above technical solutions solve the problem of water accumulation in the roof insulation foam board inside large-span roofs by heating and evaporation.

[0005] Specifically, the heat insulation sponge layer is composed of multiple heat insulation sponge boards; the heat insulation sponge boards are arranged in parallel with a certain gap between each pair of heat insulation sponge boards.

[0006] Specifically, the heating layer consists of multiple heating tubes arranged in parallel with a 10cm distance between each pair of heating tubes.

[0007] Specifically, the steam exhaust bend includes a straight pipe section and a bend section. The upper end of the straight pipe section is fixedly connected to the lower end of the bend section, and the lower end of the straight pipe section is connected to the second heating layer.

[0008] Specifically, the sensor uses a humidity-sensitive capacitor and is located at the bottom of the straight tube section. 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 a humidity-sensitive capacitor are high sensitivity, good product interchangeability, fast response speed, low humidity hysteresis, ease of manufacturing, and ease of miniaturization and integration. Its accuracy is generally lower than that of a humidity-sensitive resistor.

[0009] By adopting the above technical solution, the heating tube is used to evaporate the water accumulated in the roof insulation sponge board inside the large-span roof. The temperature of the heating tube is fixed at 100°C. The sensor monitors the humidity and temperature of the heating tube installation area in real time through wireless technology. When the temperature is too high (reaching 110°C) 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 heating tube from working.

[0010] A second aspect of this application provides a method for cleaning water accumulated in the internal insulation sponge panels of a large-span roof using heating and evaporation, comprising the following steps: A heat insulation sponge layer is installed inside the roof. The heat insulation sponge layer includes a first heat insulation sponge layer and a heat insulation sponge layer. A heating element is installed above the first heat insulation sponge board to form the first heating layer, with the heating elements arranged in parallel pairs 10cm apart. A second heating layer is formed by installing heating tubes above the first heating layer, with the heating tubes arranged in parallel with each other 10cm apart, and a steam exhaust space is left between the second heating layer and the first heating layer for exhausting steam. A heat-insulating sponge layer is laid in the steam exhaust space; A steam exhaust bend is installed above the second heating layer, such that one end of the steam exhaust bend is connected to the second heating layer and the other end extends out of the roof; Install a sensor at the bottom of the steam exhaust bend; The first and second heating layers are turned on, and the humidity and temperature at the lower end of the steam exhaust bend are detected in real time by sensors. When the humidity at the lower end of the steam exhaust bend meets the requirements or the temperature exceeds the preset value, the first and second heating layers stop heating.

[0011] Specifically, the insulation foam boards are arranged in parallel within the insulation foam layer, with a certain gap between each pair of insulation foam boards.

[0012] Specifically, once the sensor is installed, a computer control program is used to test whether the heating element will automatically stop heating when the specified temperature or humidity is reached.

[0013] By adopting the above technical solution, after laying the base layer of the internal heat insulation sponge board of the large-span roof, the first heating layer is installed and space is reserved for steam to be discharged upwards. After installation, the heat insulation sponge board is directly installed on the first heating layer. After the heat insulation sponge board is installed, the second heating layer is installed, the position of the steam discharge pipe is marked and the straight pipe is installed, and the sensor is installed at the position of the discharge pipe. The computer control program is used to test whether the heating pipe will automatically stop working when the specified temperature / humidity is reached. The large-span roof installation is carried out normally. When the installation is completed, the heating control test and sensor detection test are performed (whether the heating pipe will automatically stop working when the specified temperature / humidity is reached).

[0014] The beneficial effects of this application are as follows: because water accumulation in the internal roof insulation sponge board of a large-span roof can easily lead to safety accidents and the solution is not convenient enough, the device is designed to solve the problem of water accumulation in the internal roof insulation sponge board of a large-span roof by heating and evaporation.
