Description

Technical Field

[0001] The utility model discloses a roof antifreeze drainage structure for cold regions, belonging to the technical field of roof antifreeze drainage. Background Art

[0002] In cold regions, roof antifreeze drainage is an important engineering consideration. On the one hand, the accumulation of ice and snow will increase the burden on the roof, which may cause structural damage or even collapse. The use of artificial ice and snow removal is not only labor-intensive, but also has certain operational risks. It may damage the waterproof layer, insulation layer or other structures of the roof, resulting in leakage and structural problems. On the other hand, when the temperature is below freezing, snow or frozen water on the roof may penetrate into the roof structure, causing roof damage, structural corrosion, and even affecting the overall stability of the building. Moreover, the melting of a large amount of ice and snow will cause water accumulation on the roof, which may cause leakage and other problems. Therefore, in cold regions, the application of roof antifreeze drainage structure is crucial. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the restrictive conditions for the implementation of the utility model, so they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical contents disclosed by the utility model. It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0027] The utility model provides the following embodiments.

[0028] like Figure 1-Figure 5 As shown, the utility model is a cold region roof antifreeze drainage structure, comprising: a roof 1, a gutter 2, a connecting pipe opening 3 and a solar photovoltaic power generation system 4, the roof 1 is a slope roof, the gutter 2 is arranged below the edge of the roof 1, a connecting pipe opening 3 with a funnel-shaped interior is arranged below the gutter 2, the connecting pipe opening 3 is connected to a drainage pipe, and the solar photovoltaic power generation system 4 is arranged on the roof 1;

[0029] The roof 1 includes a breathable waterproof membrane 5, an expanded vermiculite layer 6, a silicon carbide material layer 7, a heating wire layer 8, a heat conducting plate 9, a roofing board 10, a rock wool layer 11, an asphalt shingle layer 12 and a waterproof coating layer 13, which are arranged in sequence from bottom to top. The heating wire layer 8 includes a heating wire 14 and a thermostat. The heating wire 14 is coiled between the silicon carbide material layer 7 and the heat conducting plate 9. A plurality of temperature sensing probes 15 of the thermostat are distributed between the silicon carbide material layer 7 and the heat conducting plate 9.

[0030] The solar photovoltaic power generation system 4 is electrically connected to the heating wire 14 and the temperature controller. The specific connection method is well known to relevant technical personnel.

[0031] When the temperature is warm and there is no ice or snow, the solar photovoltaic power generation system 4 can also power the electrical appliances in the house;

[0032] When there is snow or ice on the roof, the heating wire layer 8 starts working. As the heating wire 14 heats up, when the temperature detected by a temperature sensing probe 15 exceeds the preset maximum temperature, the power is cut off, the heating wire 14 stops heating, and the overall temperature of the roof 1 begins to slowly drop. When the temperatures detected by all the temperature sensing probes 15 are lower than the preset minimum temperature, they are turned on, and the heating wire 14 starts heating again to maintain the temperature of the roof 1, continuously melt the ice and snow, and avoid the danger of excessive temperature.

[0033] The expanded vermiculite layer 6 and the rock wool layer 11 can well ensure the temperature in the house, and can also evenly transfer the heat generated by the heating wire layer 8 to the snow and ice, so that the snow and ice on the roof 1 are completely melted. On the other hand, the heat conduction time of the heat conducting plate 9 can also be extended.

[0034] The heating wire layer 8 further includes a controller and a wireless communicator, and the controller is electrically connected to the wireless communicator and the heating wire 14. The controller controls the heating wire 14 to heat and stop heating according to the control instructions received by the wireless communicator. In this way, a remote control switch can be realized. How to connect the controller and the wireless communicator to realize a remote control switch is well known to relevant technicians.

[0035] The roof 1 further includes a polystyrene foam layer 16 , which is disposed between the roof panel 10 and the rock wool layer 11 .

[0036] The material of the waterproof coating layer is polyurethane waterproof coating.

[0037] The roof 1 is a double-slope roof, and two eaves gutters 2 are respectively arranged below two slope surfaces, and a connecting pipe opening 3 is respectively arranged below the two ends of the eaves gutters 2.

[0038] A groove-shaped drainage channel 17 is respectively arranged at the bottom of the two eaves gutters 2. One end of the bottom of the drainage channel 17 is higher than the other end, and a connecting pipe opening 3 is arranged below the lower end.

[0039] The roof 1 can also be a four-slope roof, and the eaves gutter 2 is arranged under the four slopes to form a circle.

[0040] A groove-shaped drainage channel 17 is arranged in the eaves 2. The bottom of the drainage channel 17 is a structure with four corners being low and the middle being high. A connecting pipe opening 3 is arranged below each of the four corners of the drainage channel 17.

[0041] The drainage channel 17 provided in the eaves gutter 2 plays a role in guiding drainage on the one hand, and in collecting accumulated water on the other hand.

[0042] In cold areas, when the temperature drops and snow or ice accumulates on the roof, the solar photovoltaic power generation system 4 supplies power to the heating wire layer 8, the heating wire 14 starts to heat up, the silicon carbide material layer 7 and the heat conducting plate 9 quickly transfer the heat to the upper and lower layers, and the rock wool layer, polystyrene foam layer and expanded vermiculite layer in the upper and lower layers evenly conduct the heat outward to melt the snow and ice, so that they melt into water and flow into the gutter 2 along the sloping roof, and then drain through the drainage channel 17 and the drainage pipe. In this way, snow or ice will not accumulate on the roof for a long time, the roof structure is protected, and the work of manual snow and ice removal is also eliminated.

[0043] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
