AI Technical Summary
The metal roof of a steel structure factory building bears a lot of pressure when snow accumulates and is difficult to drain, which can easily lead to collapse. In summer, the high heat conduction efficiency leads to high indoor temperatures. Existing snow removal methods are time-consuming, labor-intensive, and dangerous, and the snow is difficult to melt.
It uses components such as main ridge tiles, mounting boxes, filters, drive housings, turbo fans, electric heating plates, and photovoltaic panels. By controlling three-way valves and air supply pipes, it achieves snow melting and indoor cooling. It uses flexible pipes to conduct warm air to heat the snow, and combines shading cloth to regulate sunlight, thus achieving rapid snow melting and indoor temperature regulation.
In summer, ventilation and cooling are used, and shading cloths regulate sunlight to avoid high temperatures. In winter, electric heating plates melt snow, and flexible pipes conduct warm air to accelerate the melting of snow and prevent roof damage, achieving safe and efficient drainage and snow removal.

Description
Technical Field
[0001] This invention relates to the field of building drainage technology, and more particularly to a metal roof drainage and snow removal structure. Background Technology
[0002] Steel structure buildings, compared to traditional reinforced concrete buildings, offer advantages such as faster construction and easier recycling, making them frequently used for factory buildings. These steel structure factory buildings often have large spans, resulting in large metal roof areas supported by steel beams. This means they bear significant pressure when carrying snow, which cannot be effectively dissipated, increasing the risk of collapse. Furthermore, existing metal roofs, due to cost and construction constraints, often have gentle slopes, hindering rainwater and snow drainage. Manual snow removal is not only time-consuming and labor-intensive but also carries risks related to working at heights and the risk of snow slippage. Traditional metal roofs also have high heat conductivity, easily fluctuating with outdoor temperatures. This can lead to high indoor temperatures in summer and difficulty heating up in winter when covered by snow, hindering snow melting and highlighting their shortcomings. Summary of the Invention
[0003] The purpose of this invention is to provide a metal roof drainage and snow removal structure to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A metal roof drainage and snow removal structure includes a main ridge tile, a mounting box, a secondary ridge tile, a filter screen, a front drive housing, a rear drive housing, a ventilation housing, a main exhaust port, a secondary exhaust port, an air inlet, a three-way valve, a connector, a toggle shaft, a lower toggle paddle, a support shaft, a turbofan, a one-way valve, a flexible pipe, an electric heating plate, a heat insulation layer, a photovoltaic panel, and auxiliary components. The mounting box is fixed to the top of the main ridge tile, and the secondary ridge tile is fixed to the top of the mounting box. Filter screens are fixed to the left and right sides of the mounting box, and multiple front drive housings, rear drive housings, and ventilation housings are fixed inside. Each front drive housing and rear drive housing has a main exhaust port, a secondary exhaust port, and an air inlet. The air inlet and main exhaust port are respectively connected to the inner cavities of the front drive housing and the rear drive housing. The auxiliary exhaust port is connected to the air inlet. A three-way valve is installed in both the air inlet and the auxiliary exhaust port. Each air inlet is equipped with a connector and is connected to the mounting box. Vertical actuating shafts are rotatably connected to the front drive housing and the rear drive housing. Each actuating shaft is coaxially fixed with a lower actuating paddle. Each ventilation housing is rotatably connected with a vertical support shaft. Each support shaft is coaxially fixed with a turbofan. A one-way valve is installed on the top of each ventilation housing. Each connector is connected to a flexible tube. An electric heating plate is fixed at the bottom of each flexible tube. A heat insulation layer is covered on the top of each electric heating plate. A photovoltaic panel is fixed on the top of the heat insulation layer. Auxiliary parts are also installed in each flexible tube and the mounting box.
[0005] Based on the above technical solution, the auxiliary part includes a controller, ventilation pipe, exhaust pipe, main support base, secondary support base, support roller, sunshade cloth, limit strip, upper actuating paddle, flat spiral spring, fixing base, water collection tank, drain pipe, mounting sleeve, mounting base, mounting hoop, and air supply pipe. The controller is fixed inside the mounting box. Each of the secondary exhaust ports is connected to a ventilation pipe, and each of the ventilation pipes is provided with an inclined downward exhaust pipe. Two main support bases and two secondary support bases are fixed at the front and rear ends of the inner wall of the mounting box. The main support base and secondary support base are rotatably connected to the support roller. The outer circumferential wall of the support roller is wrapped with sunshade cloth, and the ends of each sunshade cloth are respectively fixed. A limit strip is fixed and inserted into the mounting box with a gap. Each of the support rollers is coaxially fixed with an upper actuating paddle and a flat spiral spring. Each of the main support seats has a fixing seat fixed on its side wall. Each fixing seat is fixed to the outermost part of the flat spiral spring. Horizontal water collection troughs are installed on the front and rear sides of the main ridge tile. Vertical drain pipes are fixed on the left and right sides of the bottom of each of the two water collection troughs, and each is fitted with a mounting sleeve. Mounting seats are fixed on the bottom of each mounting sleeve. Mounting hoops are fixed on the top of each mounting seat. Horizontal air supply pipes are fastened to the front and rear sides of the main ridge tile through each mounting hoop. The two air supply pipes are connected to the flexible pipes on the front and rear sides of the main ridge tile.
[0006] Based on the above technical solution, the actuating shaft and the support shaft are connected and driven by a transmission mechanism. The one-way valve only allows fluid to flow from bottom to top. The three-way valve is controlled by electrical energy. The three-way valve, electric heating plate, photovoltaic panel, and controller are electrically connected. The flexible tube is made of transparent material. The limiting strip is always outside the mounting box. The upper actuating paddle is located above the main exhaust port. The three-way valve can control the connection between the air inlet and the main exhaust port, as well as the connection between the air inlet and the auxiliary exhaust port. When gas is introduced into the air supply pipe, it can... The lower paddle is driven to rotate via a flexible pipe, connector, air inlet, and three-way valve, and the exhaust gas is discharged from the main exhaust port. The upper paddle is driven to rotate, and the exhaust gas is discharged from the filter screen. When the lower paddle rotates, it can drive the support shaft and turbofan to rotate through the transmission mechanism. When the upper paddle rotates, it can drive the support roller to rotate synchronously, thereby releasing the sunshade cloth and causing the planar spiral spring to be elastically compressed. When gas is introduced into the air supply pipe, it can be discharged through the flexible pipe, connector, air inlet, three-way valve, secondary exhaust port, ventilation pipe, and exhaust pipe.
[0007] Compared with the prior art, the present invention has the following advantages: In the hot summer, the present invention can cool down the photovoltaic panels by ventilating into the flexible tube, thereby avoiding the reduction of photovoltaic panel power generation efficiency caused by high temperature. It can also enable the turbine fan to rotate and the sunshade cloth to be released, thereby accelerating indoor air circulation and lowering the room temperature. The released sunshade cloth can also partially block the sun, thereby helping to lower the room temperature. In the case of snow accumulation, the electric heating plate is controlled to heat the surrounding roof panels, thereby accelerating the melting of snow. By introducing warm air into the flexible tube, the snow in contact with the flexible tube can be heated and melted. The warm air is finally discharged from the exhaust pipe, which can heat and melt the blown snow, thereby avoiding damage to the metal roof caused by long-term snow accumulation.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] like Figures 1-7As shown, a metal roof drainage and snow removal structure includes a main ridge tile 1, a mounting box 2, a secondary ridge tile 201, a filter screen 3, a front drive housing 4, a rear drive housing 5, a ventilation housing 6, a main exhaust port 7, a secondary exhaust port 8, an air inlet 9, a three-way valve 10, a connector 11, a toggle shaft 12, a lower toggle paddle 13, a support shaft 14, a turbo fan 15, a one-way valve 16, a flexible pipe 17, an electric heating plate 18, a heat insulation layer 19, a photovoltaic panel 20, and auxiliary parts 21. The mounting box 2 is fixed to the top of the main ridge tile 1. A secondary ridge tile 201 is fixed to the top of the mounting box 2. Filter screens 3 are fixed to both the left and right sides of the mounting box 2. The filter screens 3 allow air to be discharged from the mounting box 2 in a timely manner while preventing debris from entering. Multiple front drive housings 4, rear drive housings 5, and ventilation housings 6 are fixed inside the mounting box 2. Each of the front drive housings 4 and rear drive housings 5 has a main exhaust port 7, a secondary exhaust port 8, and an air inlet 9. The air inlet 9 and the main exhaust port 7 are respectively connected to the inner cavities of the front drive housing 4 and the rear drive housing 5. The auxiliary exhaust port 8 is connected to the air intake port 9. A three-way valve 10 is installed in both the air intake port 9 and the auxiliary exhaust port 8. Each air intake port 9 is equipped with a connector 11, which is connected to the mounting box 2. Vertical actuating shafts 12 are rotatably connected to the front drive housing 4 and the rear drive housing 5, respectively. Each actuating shaft 12 is coaxially fixed with a lower actuating propeller 13. Each ventilation housing 6 is rotatably connected with a vertical support shaft 14, and each support shaft 14 is coaxially fixed with a turbofan 15. Each of the ventilation housings 6 is equipped with a one-way valve 16 on its top, and each of the connectors 11 is connected to a flexible tube 17. Each of the flexible tubes 17 is fixed with an electric heating plate 18 at its bottom end. Each of the electric heating plates 18 is covered with a heat insulation layer 19 at its top end. A photovoltaic panel 20 is fixed to the top end of the heat insulation layer 19. The heat insulation layer 19 can prevent the heat from the electric heating plate 18 from being quickly conducted to the flexible tube 17, which would reduce the power generation efficiency of the photovoltaic panel 20. Each of the flexible tubes 17 and the mounting box 2 is also equipped with an auxiliary part 21.
[0018] The auxiliary part 21 includes a controller 22, a ventilation pipe 23, an exhaust pipe 24, a main support 25, a secondary support 26, a support roller 27, a sunshade cloth 28, a limiting strip 29, an upper actuating paddle 30, a flat spiral spring 31, a fixing seat 32, a water collection tank 33, a drain pipe 34, a mounting sleeve 35, a mounting seat 36, a mounting clamp 37, and an air supply pipe 38. The controller 22 is fixed inside the mounting box 2. Each of the secondary exhaust ports 8 is connected to a ventilation pipe 23, and each of the ventilation pipes 23 is provided with an inclined downward exhaust pipe 24. Two main support seats 25 and two secondary support seats 26 are fixed at the front and rear ends of the inner wall of the mounting box 2. The main support seats 25 and the secondary support seats 26 are rotatably connected to the support roller 27. The outer circumferential wall of the support roller 27 is wrapped with a sunshade cloth 28. Each end of the sunshade cloth 28 is fixed with a limiting strip 29 and is connected to the mounting box. The two-phase gap is inserted, and the limiting strip 29 can prevent the sunshade cloth 28 from being over-wound by the elastic force of the planar spiral spring 31. Each of the support rollers 27 is coaxially fixed with an upper actuating paddle 30 and a planar spiral spring 31. Each of the main support seats 25 has a fixing seat 32 fixed on its side wall. Each fixing seat 32 is fixed to the outermost part of the planar spiral spring 31. Horizontal water collection troughs 33 are installed on the front and rear sides of the main ridge tile 1. Vertical drain pipes 34 are fixed on the left and right sides of the bottom of each of the two water collection troughs 33, and each is fitted with an installation sleeve 35. The bottom of each installation sleeve 35 is fixed with an installation seat 36. The top of each installation seat 36 is fixed with an installation hoop 37. Horizontal air supply pipes 38 are fastened to the front and rear sides of the main ridge tile 1 through each installation hoop 37. The two air supply pipes 38 are connected to the flexible pipes 17 on the front and rear sides of the main ridge tile 1.
[0019] The actuating shaft 12 and the support shaft 14 are connected by a transmission mechanism, which is a known existing technology, such as belt drive. The one-way valve 16 only allows fluid to flow from bottom to top, thus ensuring that the one-way valve 16 can be shut off in time when the turbofan 15 is not rotating, thereby preventing indoor air from flowing out of the ventilation housing 6 in winter and causing a drop in room temperature. The three-way valve 10 is electrically controlled. The three-way valve 10, the electric heating plate 18, the photovoltaic panel 20 and the controller 22 are electrically connected. The flexible tube 17 is made of transparent material, thus ensuring that sunlight can irradiate the photovoltaic panel 20. The limiting strip 29 is always outside the mounting box 2. The upper actuating paddle 30 is located above the main exhaust port 7. The three-way valve 10 can control the air inlet 9 and the main exhaust port 7. The exhaust port 7 is connected to the air inlet 9 and the auxiliary exhaust port 8. When gas is introduced into the air supply pipe 38, it can push the lower paddle 13 to rotate through the flexible pipe 17, connector 11, air inlet 9 and three-way valve 10 and then discharge it from the main exhaust port 7. It can also push the upper paddle 30 to rotate and then discharge it from the filter screen 3. When the lower paddle 13 rotates, it can drive the support shaft 14 and the turbo fan 15 to rotate through the transmission mechanism. When the upper paddle 30 rotates, it can drive the support roller 27 to rotate synchronously, thereby releasing the sunshade cloth 28 and causing the planar spiral spring 31 to be elastically compressed. When gas is introduced into the air supply pipe 38, it can be discharged through the flexible pipe 17, connector 11, air inlet 9, three-way valve 10, auxiliary exhaust port 8, ventilation pipe 23 and exhaust pipe 24.
[0020] The working principle of this invention is as follows: When in use, the main ridge tile 1 is laid between the two roof panels of the steel structure factory building, and the mounting base 36 is fixed on the wall panel of the steel structure factory building, so that the water collection tank 33 is located below the downward sloping end of the two roof panels. The electric heating plate 18 is laid on the top of the roof panel and fixed. When in a non-high temperature and non-snow-covered environment, the three-way valve 10 is completely shut off, and then a vacuum is drawn through the air supply pipe 38, so that the flexible pipe 17 is flattened and dried out, thereby reducing wind resistance and sunlight refraction, allowing the photovoltaic panel 20 to better receive sunlight and generate electricity.
[0021] When the temperature is high, the controller 22 controls the three-way valve 10 to connect the air inlet 9 and the main exhaust port 7, then ventilates the air supply duct 38. The incoming air fills the flexible duct 17 and, through the connector 11 and the air inlet 9, pushes the lower paddle 13 to rotate, then exits from the main exhaust port 7, and pushes the upper paddle 30 to rotate, then exits from the filter screen 3. The rotation of the lower paddle 13 drives the turbofan 15 to rotate through the transmission mechanism, thereby drawing air from the room and expelling it through the one-way valve 16 and the filter screen 3, thus accelerating the air circulation in the room and achieving cooling. The rotation of the upper paddle... The propeller 30 enables the support roller 27 to rotate, thereby releasing the shading cloth 28. Under the gravity of the limiting strip 29, the shading cloth 28 unfolds, providing partial shading and preventing direct sunlight from rising the room temperature. As air passes over the photovoltaic panel 20, it cools the panel, preventing overheating and reduced power generation efficiency. When ventilation stops, the lower propeller 13 and upper propeller 30 lose their propulsion, allowing the support roller 27 to retract the shading cloth 28 under the elastic force of the planar spiral spring 31 for easy reuse.
[0022] When in a snowy environment, the controller 22 controls the three-way valve 10 to connect the air inlet 9 and the secondary exhaust port 8, and heats the electric heating plate 18. Then, warm air is introduced into the air supply pipe 38. The warm air fills the flexible pipe 17 and is discharged through the connector 11, air inlet 9, secondary exhaust port 8, ventilation pipe 23 and exhaust pipe 24. The gradual heating of the electric heating plate 18 can conduct heat to the nearby roof panels, thereby melting the surrounding snow. The filled flexible pipe 17 can melt the snow covering it and the snow in contact with it. At the same time, it can prevent the photovoltaic panel 20 from being blocked by snow and can be exposed to sunlight, so as to continue to generate electricity. It can also ensure that the temperature of the photovoltaic panel 20 is suitable and ensure its power generation efficiency. The warm air discharged from the exhaust pipe 24 can heat the snow it blows and promote its melting.
[0023] Whether it is snowmelt or rainwater, after flowing out from the secondary ridge tile 201 and the main ridge tile 1, it can flow into the water collection trough 33 and finally be discharged from the drain pipe 34, thus realizing drainage.
[0024] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
