[0002] With the acceleration of urbanization, the building density is increasing, and people's requirements for living and working environment are also increasing. Among them, the roof design of the building is not only related to the aesthetics, but more importantly, it affects the safety, durability and energy efficiency of the building. Especially in cold areas, rain and snow are frequent in winter. Snow on the roof will not only increase the load-bearing burden of the roof, but may also cause damage to the roof structure and even collapse accidents, seriously threatening people's lives and property safety. In addition, long-term accumulation of rain and snow will accelerate the aging of roof materials, shorten the service life of the building, and may cause energy waste.

[0076] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0077] The present invention relates to a method for automatically preventing rain and snow from accumulating on a roof. Figure 10 to Figure 11 As shown: including laying in sequence:

[0078] The heat insulation layer 10 is used to reduce the transfer of heat to the bottom of the roof. The heat insulation layer 10 can be made of polystyrene foam board, polyurethane foam, rock wool board, etc. as the heat insulation material;

[0079] The heat storage material layer 20 is disposed on the surface of the heat insulation layer 10, and is used to absorb and store solar heat during the day, and release the stored heat to the roof surface when needed to promote the rapid melting of the bottom layer of snow;

[0080] The method further includes establishing an automatic control system 40 connected to the heat storage material layer 20 for automatically controlling the start and stop of heat release of the heat storage material layer 20 according to the snow accumulation on the roof and the external environmental conditions;

[0081] Startup conditions: When the snow thickness reaches a preset threshold and the ambient temperature is below a certain critical point, the automatic control system 40 will automatically activate the heat storage material layer 20 and start the heating process;

[0082] Stop condition: When the snow melts completely or the ambient temperature rises to a level where heating is no longer necessary, the system will automatically shut down the heating function of the heat storage material layer 20;

[0083] By using automated control methods to promptly clear snow from the roof, damage to the roof structure or even the risk of collapse due to excessive snow can be effectively avoided, thereby ensuring the safety and service life of the building. The use of heat storage materials to absorb solar energy during the day and release heat at night or when needed, this way of utilizing natural energy reduces dependence on traditional electricity or other fossil fuels, helps to reduce energy consumption, achieve the goal of energy conservation and emission reduction, reduce the erosion of the roof caused by long-term accumulation of rainwater and snow water, helps to protect the roof structure, slow down the aging process, and extend the overall service life of the building.

[0084] As a preferred embodiment of the above, Fig.10 As shown, the heat storage material layer 20 includes:

[0085] The heat storage material core layer 201 is composed of a phase change material with high heat storage capacity. The phase change material absorbs and stores radiant heat energy from the sun during the day. The phase change material includes but is not limited to inorganic hydrated salts, inorganic molten salts, organic waxy substances, polymer phase change materials or mixtures thereof. The selection of these materials is based on the matching of their phase change temperatures with the local winter ambient temperature to ensure that the stored heat can be effectively released when needed.

[0086] Packaging layer 202: wrapped around the outside of the heat storage material core layer 201, to provide corrosion-resistant sealing for the heat storage material core layer 201. The packaging layer is used to prevent leakage of the heat storage material during the phase change process and protect the heat storage material from corrosion by the external environment. The material of the packaging layer includes but is not limited to stainless steel, titanium alloy, high-temperature ceramics or polymer composite materials.

[0087] Heat conduction enhancement layer 203: located on the side of the heat storage material core layer 201 facing the sunlight, for heat conduction. The heat conduction enhancement layer is used to accelerate the transfer of heat released by the heat storage material to the roof surface, thereby improving the efficiency of snow melting. The material of the heat conduction enhancement layer includes but is not limited to graphite sheets, thermally conductive silicone, metal thermally conductive sheets or carbon fiber composite materials;

[0088] Protective layer 204: located at the outermost layer of the heat storage material layer 20, protecting the internal structure. The protective layer 204 is used to prevent the heat storage material layer from being eroded by external factors such as rain and ultraviolet rays, and at the same time provide additional physical protection to extend the service life of the heat storage material layer. The material of the protective layer includes but is not limited to waterproof coatings, sunscreen films, polymer composite materials or metal protective nets;

[0089] Each component of the heat storage material layer 20 has clear functions and significant advantages. They work together to form an efficient, safe, environmentally friendly and durable rooftop solution for preventing rain and snow accumulation, which is of great significance for improving building performance and promoting sustainable development.

[0090] As a preferred embodiment of the above embodiment, the method further includes installing an automated rain and snow accumulation prevention device on the roof, and connecting the automated rain and snow accumulation prevention device to the automated control system 40;

[0091] The automatic control system 40 automatically controls the start and shut down of the automatic rain and snow accumulation prevention equipment on the roof according to the snow accumulation on the roof and the external environmental conditions;

[0092] By installing automated rooftop snow and rain accumulation prevention equipment and connecting it to the automated control system 40, not only the intelligence level and safety of the system are improved, but also the energy efficiency is significantly improved, the service life of the equipment is extended, and the user experience and comfort are improved. This is of great significance for improving building performance and promoting sustainable development. This innovative solution provides an efficient, reliable and environmentally friendly solution to the problem of snow accumulation on the roof.

[0093] The present invention relates to an automatic device for preventing rain and snow from accumulating on a roof. Figures 1 to 9 As shown, including:

[0094] Two support frames 1 are symmetrically arranged on the roof to carry other components. The support frames 1 serve as the supporting foundation of the entire system and can be made of high-strength steel to ensure that they will not deform when bearing;

[0095] The moving mechanism 2, both ends of which move on corresponding support frames 1, and the moving track is set parallel to the roof surface. The moving mechanism 2 is a set of mechanical structures that can slide smoothly between the two support frames 1, and is used to drive the position of the cleaning tool. The moving mechanism 2 is connected to the automatic control system 40. When the automatic control system 40 detects that the snow on the roof needs to be cleared, the moving mechanism 2 is started to drive the snow-clearing tool to move;

[0096] The rotating mechanism 3 is arranged on the moving mechanism 2 and is responsible for adjusting the working mode of the cleaning tool on the moving mechanism 2. The rotating axis of the rotating mechanism 3 is arranged perpendicularly to the moving track of the moving mechanism 2 to ensure that the distance between the cleaning tool and the roof remains stable after the angle is adjusted. The rotating mechanism 3 is connected to the automatic control system 40. When the moving mechanism 2 moves to the set end point, the snow clearing mode is controlled to be flipped and switched;

[0097] The snow shovel 4 is arranged on the rotating mechanism 3, follows the moving mechanism 2 to push the snow away from the edge of the roof, and rotates synchronously with the rotating mechanism 3, so as to facilitate the adjustment of the working position of the snow shovel 4 to realize the switching of the working mode;

[0098] The cleaning roller 5 is arranged on the rotating mechanism 3, and moves synchronously with the moving mechanism 2 to further clean the snow particles or ice residues that the snow shovel 4 cannot completely remove. The cleaning roller 5 is arranged parallel to the rotating axis of the moving mechanism 2 to ensure that the length direction of the cleaning roller 5 is the same as the roof spacing, and is synchronously rotated with the rotating mechanism 3;

[0099] The heater 6 is arranged on the rotating mechanism 3 and moves synchronously with the moving mechanism 2. The heater 6 melts ice or ice layers encountered during the cleaning process. The heater 6 is installed on the same side as the cleaning roller 5 to ensure that the cleaning roller 5 and the heater 6 are in the same mode. The heater 6 is controlled by the control mechanism 7 so that the rotating mechanism 3 is started only when it is in the resetting process after snow shoveling.

[0100] When the cleaning roller 5 contacts the roof, the heater 6 is activated, and the cleaning roller 5 is located at the front end of the moving mechanism 2 in the snow shoveling direction relative to the heater 6 .

[0101] The device has two working modes, including cleaning mode and return mode. When the amount of snow on the roof reaches a predetermined thickness or is manually started by a person, it will enter the cleaning mode to work. When the cleaning mode is completed, it will enter the return mode to reset the device. The specific working process and principles of the two modes are as follows:

[0102] In the snow shoveling mode, the rotating mechanism 3 drives the snow shoveling board 4 to flip, and after the snow shoveling board 4 is in the working position, the rotating mechanism 3 stops rotating, and the moving mechanism 2 drives the snow shoveling board 4 to move, pushing the snow away from the edge of the roof, and then the movement of the moving mechanism 2 in the snow shoveling direction stops; when the snow shoveling board 4 is in the working position, a certain gap is formed between the bottom end of the snow shoveling board 4 and the roof, which reduces the wear on the roof and the snow shoveling board 4 and prevents the impact caused by poor roof flatness and ice. At the same time, this design can also adapt to roofs of different types of structures;

[0103] In the return mode, the rotating mechanism 3 rotates in the opposite direction, and after the cleaning roller 5 and the heater 6 are flipped to the working position, the rotating mechanism 3 stops rotating. At this time, the cleaning roller 5 contacts the roof, and the heater 6 is started. Then the moving mechanism 2 drives the device to move in the opposite direction of snow shoveling. The heater 6 melts the ice or ice layer encountered during the snow shoveling process, and the cleaning roller 5 cleans the snow particles or ice debris that the snow shoveling plate 4 has not been able to completely remove.

[0104] As a preferred embodiment of the above, Figures 2 to 5 As shown, the moving mechanism 2 includes:

[0105] Two guide rails 21 are respectively arranged on a corresponding support frame 1 to provide a stable sliding path for the moving mechanism 2 to ensure that it moves smoothly along a predetermined track, and the guide rails 21 are arranged parallel to the roof surface. The guide rails 21 can be made of weather-resistant materials to resist the influence of harsh outdoor environments;

[0106] Two sliding members 22 are respectively arranged on a corresponding guide rail 21. The sliding members 22 are provided with rollers or other friction reducing structures to reduce sliding resistance, and are slidably arranged along the length direction of the guide rail 21. The rotating mechanism 3 is arranged on the two sliding members 22. The sliding members 22 carry the rotating mechanism 3 and other components to realize the overall movement on the roof;

[0107] The transmission shaft 23 is rotatably arranged on a sliding member 22. The transmission shaft 23 is fixed by a bearing seat to ensure smooth rotation. The rotation axis of the transmission shaft 23 is perpendicular to the moving track of the sliding member 22 to ensure that the distance between the cleaning tool and the roof remains stable when working.

[0108] Two transmission gears 24 are coaxially disposed on both side ends of the transmission shaft 23;

[0109] Two spur racks 25 are respectively arranged in the inner cavities of the two support frames 1, and the transmission gear 24 is meshed and connected with the spur racks 25. The transmission gear 24 cooperates with the spur racks 25 to convert the rotational motion of the conduction shaft 23 into the linear motion of the sliding member 22, and push the entire moving mechanism 2 to slide along the guide rail 21, so as to realize the reciprocating sliding of the sliding member 22. At the same time, two transmission gears 24 and two spur racks 25 are arranged, and are respectively located on the two support frames 1, so that the driving force on both sides of the moving mechanism is the same during the movement;

[0110] The driving mechanism 26 is disposed on a support frame 1 and is used to provide sufficient driving force to drive the transmission shaft 23 to rotate, thereby driving the sliding member 22 to move along the guide rail 21;

[0111] A connecting member 27, disposed on a sliding member 22;

[0112] The working principle of the mobile mechanism 2 of this device is as follows:

[0113] When the system receives the start signal, the drive mechanism 26 starts to work and transmits power to the transmission gear 24 through the conduction shaft 23. The transmission gear 24 meshes with the spur rack 25 to convert the rotational motion of the conduction shaft 23 into the linear motion of the sliding member 22 along the guide rail 21. As the sliding member 22 moves, the rotating mechanism 3, the snow shovel 4, the cleaning roller 5 and the heater 6 thereon also slide on the roof to complete the predetermined cleaning task. By controlling the forward and reverse rotation of the drive mechanism 26, the moving direction of the sliding member 22 can be changed to realize the forward and backward movement of the device to meet the needs of different working modes.

[0114] As a preferred embodiment of the above, Figures 2 to 4 As shown, a driving gear 28 is coaxially arranged on the transmission shaft 23, and the driving gear 28 is ensured to rotate synchronously with the transmission shaft 23 by key connection or other fixing methods. A driven gear 29 is coaxially arranged on the cleaning roller 5, and the driven gear 29 is ensured to rotate synchronously with the cleaning roller 5 by key connection or other fixing methods. When the cleaning roller 5 contacts the roof, the driving gear 28 is meshed and connected with the driven gear 29. The module and pressure angle of the driving gear 28 match those of the driven gear 29 to ensure good meshing performance. The connecting piece 27 and the driving gear 28 are respectively located at both ends of the snow shovel 4 to prevent the local load of the device from being too large and optimize the installation space.

[0115] The working principle of the driving gear 28 and the driven gear 29 of the device is as follows:

[0116] When the device is in the return mode, when the transmission shaft 23 rotates, the driving gear 28 rotates accordingly, and the power is transmitted to the driven gear 29 through gear meshing, thereby driving the cleaning roller 5 to rotate. The meshing connection design enables the cleaning roller 5 to roll closely against the roof surface when the moving mechanism 2 returns, further cleaning up the snow particles or ice debris that the snow shovel board 4 has not been able to completely remove.

[0117] As a preferred embodiment of the above, Figures 2 to 4 As shown, when the snow is shoveled after completion and the return journey is in a meshing state between the driving gear 28 and the driven gear 29, at which time the snow shovel board 4 is out of the working position, and the cleaning roller 5 rotates synchronously with the movement of the moving mechanism 2 to further clean the snow particles or ice debris that the snow shovel board 4 has not completely removed. When shoveling snow, the driving gear 28 and the driven gear 29 are in a meshing and disengaged state, at which time the cleaning roller 5 does not need to rotate to avoid unnecessary energy loss.

[0118] As a preferred embodiment of the above, Figure 6 to Figure 7 As shown, the driving mechanism 26 includes:

[0119] The first worm 26a is arranged on the connecting member 27 and fixed by a bearing seat to ensure smooth rotation. The rotation axis of the first worm 26a is perpendicular to the rotation axis of the transmission shaft 23 to ensure that the moving track of the first worm 26a is parallel to the length direction of the guide rail 21;

[0120] The first worm wheel 26b is coaxially arranged on the transmission shaft 23 and is ensured to rotate synchronously with the transmission shaft 23 by key connection or other fixing methods. The first worm wheel 26b is meshedly connected with the first worm 26a to transmit the rotational motion of the first worm 26a to the transmission shaft 23, so that the transmission shaft 23 rotates;

[0121] The power shaft 26c is rotatably arranged in a support frame 1, fixed by a bearing seat to ensure smooth rotation, and passes through the inner hole of the first worm 26a, so that the first worm 26a is slidably arranged along the length direction of the power shaft 26c, and the first worm 26a and the power shaft 26c rotate synchronously; the length direction of the power shaft 26c is arranged parallel to the length direction of the guide rail 21, and the power shaft 26c, as the main power transmission shaft, transmits the rotational motion to the first worm 26a, and finally drives the transmission shaft 23 to rotate through the meshing connection between the first worm 26a and the first worm wheel 26b, ensuring that the transmission relationship of the first worm 26a remains unchanged after the displacement of the moving mechanism 2;

[0122] The first servo motor 26d is arranged on the support frame 1 and is connected to the power shaft 26c through a coupling or other connection method. It serves as the power source of the entire driving mechanism 26 and provides the necessary torque and speed. The first servo motor 26d is connected to the automatic control system 40 and is started or stopped by the automatic control system 40. At the same time, when the sliding member 22 moves to the set end point, the first servo motor 26d is controlled to rotate in the opposite direction.

[0123] The working principle of the driving mechanism 26 of the present device is as follows:

[0124] When the system receives the start signal, the first servo motor 26d starts to work. The first servo motor 26d drives the power shaft 26c to rotate through a coupling or other connection methods. The rotational motion of the power shaft 26c is transmitted to the transmission shaft 23 through the meshing connection of the first worm 26a and the first worm wheel 26b. The rotational motion of the transmission shaft 23 is transmitted to the two spur racks 25 through two transmission gears 24. The meshing connection between the transmission gear 24 and the spur racks 25 converts the rotational motion of the transmission shaft 23 into the linear motion of the sliding member 22, pushing the entire moving mechanism 2 to slide along the guide rail 21. The sliding member 22 slides along the length direction of the guide rail 21, driving the rotating mechanism 3, the snow shovel 4, the cleaning roller 5 and the heater 6 to slide on the roof to complete the predetermined cleaning task. By controlling the forward and reverse rotation of the first servo motor 26d, the moving direction of the sliding member 22 can be changed to realize the forward and backward movement of the device to meet the needs of different working modes.

[0125] As a preferred embodiment of the above, Fig. 9 As shown, the rotating mechanism 3 includes:

[0126] The mounting shaft 31 has two ends which are rotatably arranged on the two sliding members 22. The mounting shaft 31 is fixed by a bearing seat to ensure smooth rotation. The mounting shaft 31 coincides with the rotation axis of the transmission shaft 23 and rotates independently with the transmission shaft 23. The mounting shaft 31 is the main supporting shaft of the rotating mechanism 3 and is responsible for carrying the snow shovel 4, the sweeping roller 5 and the heater 6 to adjust the working mode to ensure that these components can be flexibly switched under different working conditions. A fixing member 32 is arranged on the mounting shaft 31, and the snow shovel 4 is arranged on the fixing member 32. The fixing member 32 ensures that the snow shovel 4 is firmly installed by bolts or other fixing methods, and ensures that the snow shovel 4 can rotate synchronously under the drive of the rotating mechanism 3 to realize the snow shoveling function.

[0127] Two mounting members 33 are arranged on the mounting shaft 31, and the two mounting members 33 are located at both ends of the snow shovel 4. The mounting members 33 ensure that the cleaning roller 5 and the heater 6 are firmly installed by bolts or other fixing methods, ensuring that these components can rotate synchronously under the drive of the rotating mechanism 3 to achieve cleaning and heating functions;

[0128] The adjusting mechanism 34 is arranged on a supporting frame 1, and the adjusting mechanism 34 is used to provide sufficient driving force to provide the mounting shaft 31 with rotational power relative to the sliding member 22, so as to realize the switching of the working positions of the snow shovel 4, the cleaning roller 5 and the heater 6;

[0129] The working principle of the rotating mechanism 3 of this device is as follows:

[0130] Snow shoveling mode: the adjustment mechanism 34 drives the mounting shaft 31 to rotate, so that the snow shoveling plate 4 is flipped to the working position, and the cleaning roller 5 and the heater 6 are flipped to the non-working position. The mounting shaft 31 stops rotating, the snow shoveling plate 4 is in the working position, and a certain gap is formed between the bottom end and the roof. The moving mechanism 2 drives the snow shoveling plate 4 to move along the roof surface to push the snow away from the edge of the roof;

[0131] In the return mode, the adjustment mechanism 34 drives the installation shaft 31 to rotate in the opposite direction, so that the cleaning roller 5 and the heater 6 are flipped to the working position, and the snow shovel 4 is flipped to the non-working position, the installation shaft 31 stops rotating, the cleaning roller 5 contacts the roof, the heater 6 is started, and the moving mechanism 2 drives the cleaning roller 5 and the heater 6 to move along the roof surface. The heater 6 melts the ice or ice layer encountered during the snow shoveling process, and the cleaning roller 5 cleans the snow particles or ice debris that the snow shovel 4 has not been able to completely remove.

[0132] As a preferred embodiment of the above, Figure 6 to Figure 7 As shown, the adjustment mechanism 34 includes:

[0133] The second worm 34a is arranged on the connecting member 27 and fixed by a bearing seat to ensure smooth rotation. The second worm 34a is arranged perpendicular to the rotation axis of the mounting shaft 31 to ensure that the moving track of the second worm 34a is parallel to the length direction of the guide rail 21;

[0134] The second worm wheel 34b is coaxially arranged on the installation shaft 31, and is ensured to rotate synchronously with the installation shaft 31 by key connection or other fixing methods. The second worm wheel 34b is meshed with the second worm 34a, and the rotational motion of the second worm 34a is transmitted to the installation shaft 31, so that the installation shaft 31 rotates. The meshing of the worm and the worm wheel has a self-locking function, which ensures that the position of the installation shaft 31 remains stable after the angle is adjusted;

[0135] The driving shaft 34c is rotatably arranged in the support frame 1 and fixed by a bearing seat to ensure smooth rotation. The driving shaft 34c passes through the inner hole of the second worm 34a, so that the second worm 34a is slidably arranged along the length direction of the driving shaft 34c, and the second worm 34a and the driving shaft 34c rotate synchronously. The length direction of the driving shaft 34c is parallel to the length direction of the guide rail 21. The driving shaft 34c serves as the main power transmission shaft, which transmits the rotational motion to the second worm 34a, and finally drives the installation shaft 31 to rotate through the meshing connection between the second worm 34a and the second worm wheel 34b.

[0136] The second servo motor 34d is arranged on the support frame 1 and is connected to the drive shaft 34c by a coupling or other connection method to ensure that it can provide sufficient driving force to serve as the power source of the adjustment mechanism 34, provide the necessary torque and speed, drive the entire adjustment mechanism 34 to work, and realize the rotation of the installation shaft 31; the second servo motor 34d is connected to the automatic control system 40, when the sliding member 22 moves to the set end point, the automatic control system 40 controls the second servo motor 34d to rotate, so that the snow clearing mode is switched, and the second servo motor 34d stops rotating after the switching, and the next rotation of the second servo motor 34d is opposite to the previous rotation direction.

[0137] The working principle of the adjustment mechanism 34 of the present device is as follows:

[0138] When the system receives the start signal, the second servo motor 34d starts working. The second servo motor 34d drives the drive shaft 34c to rotate through a coupling or other connection methods. The rotational movement of the drive shaft 34c is transmitted to the installation shaft 31 through the meshing connection between the second worm 34a and the second worm wheel 34b, and the snow shoveling mode and the return to the city mode are switched through the installation shaft.

[0139] As a preferred embodiment of the above, Figure 6 to Figure 7 As shown, the first servo motor 26d and the second servo motor 34d are installed on the same side of the same support frame 1. This design can conveniently use a protective cover or other isolation measures to centrally protect the two motors to prevent them from being damaged by the external rain and snow environment.

[0140] As a preferred embodiment of the above, Figure 8 As shown, the control mechanism 7 includes:

[0141] A touch switch 71 is provided on the sliding member 22. The touch switch 71 is connected to the control system through a wire to ensure the reliability of signal transmission, and is used to control the start and stop of the heater 6;

[0142] The toggle rod 72 is disposed on the mounting shaft 31 and moves with the rotation of the mounting shaft 31. The length and shape of the toggle rod 72 are designed so that it can accurately contact or disengage with the touch switch 71, and is used to control the on and off of the touch switch 71, thereby controlling the start and shut down of the heater 6;

[0143] When the snow shoveling is completed and the return journey is made, the toggle lever 72 is in contact with the touch switch 71, and the heater 6 is in the start-up state;

[0144] When shoveling snow, the toggle rod 72 and the touch switch 71 are in a disengaged state, and the heater 6 is in an off state.

[0145] The present invention also relates to a method for automatically preventing rain and snow from accumulating on a roof, using the automatic roof-mounted snow and rain accumulation prevention device as described above, the steps comprising:

[0146] When shoveling snow (i.e. entering the snow shoveling mode), the rotating mechanism 3 rotates to make the snow shoveling plate 4 rotate to the lowest position higher than the sweeping roller 5 and the heater 6, and a gap is left between the lowest position of the snow shoveling plate 4 and the roof;

[0147] When returning after snow shoveling (i.e. entering return mode), the rotating mechanism 3 rotates so that the snow shoveling plate 4 is higher than the cleaning roller 5 and the heater 6, and the cleaning roller 5 contacts the roof, and the heater 6 blows air toward the roof;

[0148] The movement during snow shoveling and the return movement after snow shoveling are both powered by the moving mechanism 2.
