[0002] The large-span storage sheds all adopt steel structure roofs. The steel structure roofs are sensitive to snow loads. Especially when arranged continuously, snow is likely to accumulate at the included angle of the two-span roofs. Due to the emergence of extreme weather in recent years, large-scale snow accumulation often occurs, resulting in the collapse of the roof structure, causing great potential safety hazards, property and personnel losses. At present, there is no roof snow removal structure specifically designed for large-scale snow accumulation. Summary of the Invention

[0013] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0014] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0015] Embodiment 1

[0016] The accompanying drawings are a specific embodiment of the present invention, as Figure 1-2 shown. Figure 1The structure shown actually includes two roofs on the left and right and a snow removal system below the roofs. The lowermost part is the gutter and the gutter connector. The main body 1 of the structure is the original structure of the storage shed. In order to install the snow removal system, the original structure of the storage shed can be appropriately modified. The main components of the snow removal system include the panel 3, the main frame 5, the auxiliary frame 6, the connecting rod 4, etc. Among them, the upper surface of the panel 3 is smooth and is lapped with the lower end of the original roof 2 of the storage shed. The main frame 5, the auxiliary frame 6 and the connecting rod 4 are all arranged on the lower surface of the panel 3. The main frame 5 is located below the panel 3, the auxiliary frame 6 is located at the upper end of the panel 3, and the connecting rod 4 is between the main frame 5 and the auxiliary frame 6. The panel 3 can be fixed to the main frame 5 and the auxiliary frame 6, and the connecting rod 4 can be fixed to the panel 3, the main frame 5 and the auxiliary frame 6 by welding or bolt methods. The structure of the connecting rod 4 is thick at the bottom and thin at the top, that is, the cross-sectional area of the connecting rod 4 gradually decreases from bottom to top. The connecting rod 4 has two functions. One is to act as a reinforcing rib to increase the overall compressive capacity of the snow removal system; the other is to act as a power source for automatic opening. When the switch pin 7 is opened, it can drive the panel 3 to flip and return under the action of gravity. The main frame 5, the auxiliary frame 6 and the main body 1 of the structure are connected through components such as the rotating shaft 8, the rotating shaft connector, the switch pin 7, the slide rail 9, etc. The structures at the connections between the two ends of the main frame 5 and the auxiliary frame 6 and the main body 1 of the structure are the same. The following describes one side as an example. Holes are drilled at the corresponding positions of the main frame 5 and the main body 1 of the structure, and the inner diameter of the holes is slightly larger than that of the rotating shaft 8. The rotating shaft 8 passes through the retaining holes on the main frame 5 and the main body 1 of the structure, so that the main frame 5 can rotate relative to the main body 1 of the structure; the rotating shaft connector is a limiting structure for the rotating shaft 8, as long as it can prevent the rotating shaft 8 from disengaging from the main frame 5 or the main body 1 of the structure during the rotation process. In order to facilitate the return after rotation, the rotating shaft 8 can adopt a spring bolt or a spring can be sleeved outside the rotating shaft 8, and the two ends of the spring are respectively fixed to the main body 1 of the structure and the rotating shaft 8. The thickness, specifications of the spring, spring bolt, the rotating shaft connector, etc. can all be commercially customized according to needs, as long as the effect of automatic resilience can be achieved. The handle of the switch pin 7 is located on one side of the auxiliary frame 6, and a corresponding slot is welded on the main body 1 of the structure. The switch pin 7 is inserted into the slot to fix the overall structure. When the switch pin 7 is pulled out of the slot, the main body part of the system can be rotated and opened. In order to facilitate the opening and closing of the switch pin 7, rollers that can freely rotate at the bottom of the switch pin 7 are arranged at one end close to the main body 1 of the structure. One or more groups of rollers can be arranged, symmetrically arranged on both sides of the bottom of the switch pin 7, and slide rails 9 are arranged on the main body of the structure corresponding to the rollers. The panel 3 is preferably made of lightweight materials such as membrane materials, profiled steel sheets or sandwich panels, etc.

[0017] In use, first connect the main frame 5 with the connecting rod 4 and the auxiliary frame 6 to form a framework, and then connect the panel 3. After all the components are assembled, the whole is hoisted to the installation position. Secondly, connect and fix it with the main structure 1 through the rotating shaft 8, the switch pin 7, the rotating shaft connecting piece and the slide rail connecting piece to form a snow removal system. When it snows continuously, the switch pin can be opened in advance. When the snow in the gutter on the sloping roof reaches a certain thickness and the snow pressure is greater than the gravity of the connecting rod as the main body, the panel will automatically open under the action of the snow pressure, so that the excess snow is discharged, reducing the load on the structure.

[0018] When the snow accumulation is small, the switch pin can be manually opened, or not opened to let the snow melt naturally. When the snow accumulation is large or it snows continuously for several days, the switch pin can be opened, so that the snow removal system automatically opens under the action of the snow pressure to discharge the snow, and automatically rebounds and restores under the action of the rotating shaft. The rotating shaft and the rotating shaft connecting piece can be fixed with hexagon bolts. The rotating shaft can be a spring bolt with a certain elasticity to achieve the effect of automatic rebound. The upper part of the switch pin is provided with a handle, and the bottom is provided with a pulley device, which can slide freely on the slide rail connecting piece to open or close.

[0019] One end of the connecting rod where it is fixed should have a greater stiffness than the freely rotating end, that is, the form of thicker at the bottom and thinner at the top. A rod with a variable cross-section can be used. In the case of pulling out the switch pin, it is ensured that the snow removal system will not open under its own weight. The length of the connecting rod and the size of the variable cross-section, or the distance between the rotating shaft and the switch pin, can be designed according to the local actual snow load situation or usage requirements to adapt to the difficulty of automatic snow removal under different snow load conditions.

[0020] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
