[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The purpose of the present invention is to provide a building snow removal device to solve the problems existing in the above-mentioned related technologies, improve the efficiency of building snow removal, and at the same time enhance the convenience of building snow removal.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The present invention provides a snow removal device for buildings, please refer to Figure 1-Figure 8 , including a ceiling mechanism, which is arranged on the top of the main structure 4 of the building, and the ceiling mechanism includes a supporting keel 1, a ceiling cover plate 2 and a heating element 3, the supporting keel 1 is connected to the main structure 4 of the building; the ceiling cover plate 2 is slidably connected to the supporting keel 1, the ceiling cover plate 2 covers the top surface of the main structure 4 of the building, and the sum of the top surface areas of all the ceiling cover plates 2 is greater than the top surface area of ​​the main structure 4 of the building; the ceiling cover plate 2 can reciprocate from the first end to the second end of the supporting keel 1, and the distance between the first end of the supporting keel 1 and the foundation where the main structure 4 of the building is located is greater than the distance between the second end of the supporting keel 1 and the foundation where the main structure 4 of the building is located; the heating element 3 is arranged on the side of the ceiling cover plate 2 close to the inner side of the main structure 4 of the building, and the heating element 3 can generate heat and exchange heat with the ceiling cover plate 2.

[0035] The building snow removal device of the present invention has a ceiling mechanism arranged on the top of the main structure 4 of the building, and the ceiling mechanism includes a supporting keel 1 and a ceiling cover plate 2, the ceiling cover plate 2 is slidably connected to the supporting cover plate, and the ceiling cover plate 2 slides back and forth in the direction from the first end to the second end of the supporting keel 1, the distances between the first end and the second end of the supporting keel 1 and the foundation are different, the first end of the supporting keel 1 is higher, and the second end is lower, during the reciprocating sliding of the ceiling cover plate 2, when the ceiling cover plate 2 changes the sliding direction, the accumulated snow covering the ceiling cover plate 2 continues to keep in motion due to inertia, and coupled with the effect of gravity, the accumulated snow slides off the ceiling cover plate 2 to achieve snow removal, and the ceiling cover plate 2 "shakes off" the accumulated snow. In actual applications, the reciprocating motion amplitude and frequency of the ceiling cover plate 2 are controlled, and the shaking amplitude and frequency of the ceiling cover plate 2 can be adjusted to achieve different snow removal requirements. At the same time, the heating element 3 arranged on the inner side of the ceiling cover plate 2 can generate heat and transfer heat to the ceiling cover plate 2, so that the accumulated snow melts, and the melted snow water slides down and flows away under the action of gravity, further improving the snow removal efficiency. The building snow removal device of the present invention has high snow removal efficiency, greatly reduces the labor burden of operators, and improves the convenience of building snow removal. It should also be noted that in actual applications, the movement state of the ceiling cover plate 2 and the working state of the heating element 3 can be adjusted according to the degree of snow accumulation in the building to meet different snow removal conditions, thereby improving the snow removal efficiency, enhancing the flexibility and adaptability of the device, and saving snow removal costs.

[0036] In this specific embodiment, the support keel 1 is an arched structure, and the support keel 1 is arranged across the top of the main structure 4 of the building to provide stable support for the ceiling cover 2. At the same time, if the ceiling cover 2 slides back and forth in the horizontal direction, the accumulated snow also moves in the horizontal plane and cannot slide off the ceiling cover 2. Therefore, the support keel 1 is set to an arched structure, so that the ceiling cover 2 has a certain angle with the horizontal plane along the reciprocating sliding direction of the support keel 1, so that the accumulated snow can slide smoothly during the reciprocating movement of the ceiling cover 2; in practical applications, the support keel 1 can also be set to an inverted V-shaped, herringbone and other structures, and the specific shape of the support keel 1 can be adjusted according to the requirements of the main structure 4 of the building. Accordingly, the shape of the ceiling cover 2 can be adaptively changed according to the shape of the support keel 1. In order to provide stable support for the ceiling cover 2, the number of the support keels 1 is multiple groups, and the support keels 1 are arranged in parallel. The support keels 1 can be arranged in an equidistant arrangement to improve the force uniformity of the main structure 4 of the building and the ceiling cover 2.

[0037] Among them, two ceiling cover plates 2 are arranged between each two adjacent supporting keels 1, and the two ceiling cover plates 2 are symmetrically arranged with the arch axis of the supporting keel 1 as the symmetry axis, which is convenient for the construction of the ceiling mechanism. It should be explained here that the two ceiling cover plates 2 need to avoid interference when they reciprocate along the supporting keel 1. It is a common practice for those skilled in the art to reasonably set the connection structure between the ceiling cover plates 2 and the supporting keel 1 and set the movement stroke of the ceiling cover plates 2 to avoid movement interference, which will not be repeated here.

[0038] Specifically, the two ceiling cover plates 2 between each two adjacent supporting keels 1 are overlapped to ensure that the ceiling cover plates 2 can fully cover the top of the main structure 4 of the building, while providing a certain movement space for the reciprocating sliding of the ceiling cover plates 2 to avoid gaps in the ceiling mechanism that affect the integrity of the top structure of the building.

[0039] In order to improve the reciprocating sliding accuracy of the ceiling cover plate 2, the supporting keel 1 has a keel slide groove 5, and the ceiling cover plate 2 can slide into the keel slide groove 5. The ceiling cover plate 2 cooperates with the keel slide groove 5, which improves the movement accuracy of the ceiling cover plate 2 and effectively avoids the dislocation of the ceiling cover plate 2. While eliminating snow accumulation, the working reliability of the ceiling mechanism is guaranteed. It should be noted here that the two ceiling cover plates 2 are arranged as an overlap structure, and the corresponding structure at the sliding connection between the supporting keel 1 and the ceiling cover plate 2 is also provided with an overlapped keel slide groove 5 adapted to the two ceiling cover plates 2.

[0040] In this specific embodiment, the keel slide groove 5 is a U-shaped groove, which provides a guide for the sliding of the ceiling cover plate 2 and facilitates the disassembly and assembly of the ceiling cover plate 2, thus providing convenience for subsequent maintenance and replacement.

[0041] In addition, in this specific embodiment, the supporting keel 1 is arched and the ceiling cover plate 2 is a curved panel. In order to enable the ceiling cover plate 2 to slide smoothly along the keel groove 5 of the supporting keel 1, the height dimension of the keel groove 5 is greater than the thickness dimension of the ceiling cover plate 2, providing sufficient movement space for the top spray cover plate.

[0042] In practical applications, the ceiling cover plate 2 is connected with a driver, and the driver is connected to the ceiling cover plate 2 by a transmission assembly. The driver can drive the ceiling cover plate 2 to reciprocate, and each ceiling cover plate 2 can realize linkage by a transmission assembly to improve the control convenience of the ceiling cover plate 2. The transmission assembly can select a chain transmission structure, a belt transmission structure or a gear transmission structure, etc., and select a suitable transmission structure to drive the ceiling cover plate 2 to reciprocate, which belongs to the conventional means of those skilled in the art, and will not be repeated here. It should also be noted that in practical applications, a controller and a control switch 6 can be set, and the driver and the control switch 6 are connected to the controller for communication to control the motion state of the ceiling cover plate 2. In addition, the control switch 6 can be set inside and / or outside the main structure of the building to improve the convenience of control operation. The controller can also have a built-in remote communication module to facilitate remote control by the operator, further reduce the labor burden of the operator, and improve the convenience of operation. Similarly, the heating element 3 can be provided with a heating switch for convenient control. Among them, the structure and working principle of the controller belong to the conventional means of those skilled in the art, and will not be repeated here.

[0043] In practical applications, the ceiling cover 2 can be made of hydrophobic glass material to further improve the snow removal efficiency. When the liquid contacts the solid surface, it will form a certain thickness instead of being fully expanded and spread on the solid. The side of the liquid that is not in contact with the solid will form a circular arc surface, which has a certain angle with the solid-liquid interface. This angle is called the contact angle θ. When the contact angle is greater than 150°, it is super hydrophobic. The ceiling cover 2 of the present invention is made of hydrophobic glass material, so that the melted snow water slides smoothly. Considering the durability of hydrophobic glass, etching can be used. Etching is a common method for preparing super hydrophobic glass surfaces. It mainly includes chemical etching, electrochemical etching, plasma etching and photo etching. Among them, chemical etching is simple to operate and has low requirements for experimental equipment; electrochemical etching is currently the most direct and efficient method for constructing super hydrophobic glass surfaces; plasma etching is suitable for constructing patterns with high density and complex structures; photo etching is suitable for constructing patterns with various shapes. A hard template with a micro-nano structure pattern is constructed on the glass surface using a laser, and then polydimethylsiloxane (PDMS) and a curing agent are poured on the hard template to obtain an elastic template. The PDMS polymer is poured on the surface of the elastic template. After baking and curing, the polymer surface forms a super-hydrophobic surface material with a micro-nano structure similar to the original template. The angle θ between the surface material and water can reach more than 150 degrees. Since the contact area between the super-hydrophobic glass surface and the water droplets is very small, and the surface is slightly tilted, the water can roll off the surface. It not only has self-cleaning function, but also has anti-icing, high-transmittance anti-fouling, anti-fogging and other functions. It can be achieved that it is not easy to ice on the upper part of buildings such as stadiums, while also ensuring the light transmittance.

[0044] In other specific implementations of the present invention, a hydrophobic structural layer may be provided on the top surface of the roof cover plate 2, which is also conducive to the removal of snow.

[0045] More specifically, the heating element 3 also has an illumination structure 7, which is located on the side of the heating element 3 away from the ceiling cover plate 2. While heating to generate heat to melt the snow on the ceiling cover plate 2, it has an illumination function, thereby improving the flexibility and adaptability of the heating element 3. In practical applications, the heating element 3 can use PTC material to generate heat. PTC material is a special polymer material or semiconductor material doped with an appropriate amount of conductive particles. This material has the characteristic of a positive temperature coefficient, that is, its resistance value increases significantly with increasing temperature. Conversion of electrical energy into thermal energy: According to Ohm's law, heat is generated when current passes through a resistor. In a PTC material, when current passes through, a certain amount of heat is generated due to the resistance of the material itself. Resistance change and heat generation: As the temperature of the PTC material increases, its resistance value gradually increases. According to Ohm's law, the increase in resistance leads to a decrease in the current passing through the material, thereby reducing the heat directly generated by the current. However, when the temperature reaches the Curie temperature, the sharp increase in resistance actually limits the further increase in current, avoiding overheating caused by excessive current. Self-limiting temperature function: This characteristic of PTC materials makes it have a self-limiting temperature function. In the PTC heating element, when the surface temperature of the element reaches a certain temperature, the sharp increase in resistance limits the current and heat generation, thereby achieving automatic control and stabilization of the temperature. By using this PTC material as a resistor for heating, the snow on the top of the building can be effectively heated to make it melt quickly, and the temperature can be effectively controlled to prevent excessive temperature from causing damage to the equipment on the top of the building.

[0046] In the building snow removal device of the present invention, the roof cover plate 2 slides back and forth relative to the supporting keel 1, so that the snow covering the roof cover plate 2 is "shaken off", and the heating element 3 is used to generate heat to melt the snow.

[0047] When there is light snow, that is, a small amount of snow covers the top of a building (such as a stadium), the heating element 3 can be used alone. By turning on the heating switch, the small amount of snow on the top can be melted into water and drained away naturally.

[0048] When there is heavy snow, that is, when the top of the building is covered with a large amount of snow, the roof cover 2 can be used to "shake off" the snow, and work together with the heating element 3. By turning on the control switch 6 and the heating switch, the lower part of the snow is melted into water through heating. In addition, the roof cover 2 reciprocates relative to the supporting keel 1, which can make the snow slide off quickly and improve the snow removal efficiency.

[0049] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
