Description

Technical Field

[0001] The invention relates to the technical field of tent building design, in particular to an aluminum alloy tent with an automatic snow removal system. Background Art

[0002] In recent years, with the frequent occurrence of extreme weather, the problem of snow accumulation on roofs in winter has become increasingly significant in affecting the safety of buildings and personnel activities, especially temporary buildings such as aluminum alloy tents, which have weaker bearing capacity than steel and concrete structures, and the safety risks caused by snow accumulation are also higher.

[0003] At present, the removal of snow on the roof mainly relies on manual operation, and workers need to use tools (such as snow shovels, brooms, etc.) to manually remove the snow on the roof. However, traditional manual snow removal methods have significant defects: first, they are inefficient and labor-intensive, especially in large tents or continuous snowfall scenes, which require repeated operations and are time-consuming and labor-intensive; second, aluminum alloy tents mostly use sloping roofs, and workers are prone to falling accidents due to factors such as slippery and improper operation, which poses a prominent safety hazard; third, it is difficult to accurately control the force of manual snow removal, which may damage the roof structure and increase subsequent maintenance costs.

[0004] In order to improve the above problems, some designers have proposed relevant technical solutions for mechanical snow removal on roofs, such as automatic operation through track-type snow shoveling mechanisms, rotating sweeping brushes or vibrating snow removal equipment. For example, the Chinese invention patent technology of sloped roof snow removal equipment with announcement number CN111021643B developed by Hebei University of Science and Technology replaces manual snow removal operations by setting a snow shovel that can slide along the inclined direction and a matching power system on the sloped roof. However, the existing mechanical solutions still have obvious shortcomings: on the one hand, most devices rely on complex transmission structures (such as multi-stage gear sets, hydraulic systems or motor arrays), resulting in high manufacturing costs, and complex mechanical structures are relatively poor in stability under harsh working conditions such as low temperatures and snow compaction, and are prone to failures that affect the snow removal effect; on the other hand, too many and too heavy mechanical equipment have high requirements on the roof's load-bearing capacity, and are difficult to apply to lightweight buildings with weak load-bearing capacity such as aluminum alloy tents.

[0005] In summary, there is an urgent need for a roof snow removal solution that is lightweight, low-cost and highly stable, in order to break through the dual limitations of traditional manual and existing mechanical snow removal solutions and meet the actual needs of diverse building scenarios, especially lightweight buildings such as aluminum alloy tents. Summary of the invention

[0006] In order to solve the shortcomings of the background technology, the present invention provides an aluminum alloy tent with an automatic snow removal system, which uses a nozzle to form high-pressure gas to remove snow from the roof, and the heating wire avoids ice blockage. By controlling the opening sequence, snow can be removed layer by layer from top to bottom. The probability of failure is small, the stability is strong, and it is beneficial to weight load and cost control.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an aluminum alloy tent with an automatic snow removal system, comprising a tent frame, a control cabinet, a snow amount sensor and a plurality of nozzles, the tent frame is assembled and fixed by aluminum alloy profiles to form a sloped roof and its supporting structure, and a tarpaulin with a clip strip is installed on the surface of the tent frame, the plurality of nozzle arrays are arranged on the roof surface and are inclined downward on the slope, a heating wire is arranged at the outlet end of each nozzle, a solenoid valve is installed at the connection end of each nozzle and is connected and fixed to an air supply pipeline pre-buried in the aluminum alloy profile, the control cabinet is provided with an air compressor connected to the air supply pipeline to provide an air source, the snow amount sensor is installed on the roof to detect snow accumulation signals and transmit them to the control cabinet, the control cabinet has a built-in control system that can control the opening sequence of the solenoid valves and the switching tasks of all heating wires, and the nozzles are opened row by row from top to bottom by controlling the corresponding solenoid valves to realize layer-by-layer sweeping of snow on the roof, the action range of each nozzle is fan-shaped, the row spacing between two adjacent nozzles is not greater than the radius of the fan, and the column spacing between two adjacent nozzles is not greater than the length of the line segment where the two ends of the arc of the fan are located.

[0008] Furthermore, the roof of the tent frame adopts a Λ-shaped double-slope structure, including multiple tent roof main beams and multiple tent square tubes assembled and fixed in a criss-cross shape on the slopes on both sides, and multiple supporting columns are fixed around the bottom edge of the roof of the tent frame to form a supporting structure.

[0009] Furthermore, two tensioning steel strands are fixed in an X-shaped cross between some or all of two adjacent main beams of the tent roof of the tent frame.

[0010] Furthermore, the supporting structure of the tent frame has a cross reinforcement beam fixed between two adjacent supporting columns.

[0011] Furthermore, the supporting structure of the tent frame has a cross beam fixed on the top between all two adjacent supporting columns.

[0012] Furthermore, the air pressure supplied by the air compressor of the control cabinet is 0.5-0.8 MPa.

[0013] Furthermore, the control cabinet is powered by municipal electricity and is equipped with a diesel generator as a backup power source.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention arranges a number of nozzles in an array on the roof and utilizes high-pressure gas to perform snow removal operations on the roof of an aluminum alloy tent, thereby avoiding the safety risks of manual operations and saving time and effort. Moreover, compared with traditional mechanical snow removal solutions, the present invention has no complicated transmission parts, a low probability of mechanical failure, and stronger stability. The roof components are lightweight and simple in composition, which is beneficial to the control of weight load and cost, and is beneficial to the application of large-span tents in extreme environments. The built-in heating wire in the nozzle can be preheated in advance to avoid blockage problems caused by melting and icing of accumulated snow. The opening sequence of the nozzle is controlled by an electromagnetic valve, so that the accumulated snow on the roof can be blown layer by layer from top to bottom to the ground, thereby improving operation efficiency and snow removal effect.

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] like Figure 1-2 As shown, an aluminum alloy tent with an automatic snow removal system includes a tent frame 1, a control cabinet 4, a snow amount sensor 3 and a plurality of nozzles 2, wherein:

[0021] The tent frame 1 is assembled and fixed by aluminum alloy profiles, including a roof and multiple supporting columns 1-3 arranged and fixed at its bottom edge. The roof adopts a Λ-shaped double slope structure with a high middle and low ends, including multiple roof main beams 1-1 and multiple tent square tubes 1-2 assembled and fixed in a tic-tac-toe shape on the slopes on both sides. The multiple roof main beams 1-1 are arranged along the slope direction of the roof. A tarpaulin with clip strips is installed on the surface of the tent frame 1. In order to facilitate the display of the overall structure of the tent frame 1, the tarpaulin with clip strips is not shown in the figure. In addition, in order to strengthen the structural strength and integrity of the tent frame 1, two tensioning steel strands 1-4 can be cross-fixed in an X shape between some or all adjacent two roof main beams 1-1, a cross reinforcement beam 1-5 can be fixed between some adjacent two supporting columns 1-3, and a cross beam 1-6 can be fixed on the top between all adjacent two supporting columns 1-3.

[0022] The plurality of nozzles 2 are arranged in an array on the roof surface, and the outlet ends of the nozzles 2 are kept tilted downward on the slope. The outlet ends of all the nozzles 2 are provided with heating wires. The connecting ends of all the nozzles 2 are equipped with solenoid valves 6 and are connected and fixed with the air supply pipeline 5. The air supply pipeline 5 is pre-buried in the aluminum alloy profile of the tent frame 1. The control cabinet 4 is arranged in the aluminum alloy tent and is provided with an air compressor connected to the air supply pipeline 5 to provide an air source. The air pressure supplied by the air compressor is usually 0.5-0.8 MPa. The snow amount sensor 3 is installed on the roof to detect the snow accumulation signal on the roof and transmit it to the control cabinet 4. The control cabinet 4 has a built-in control system that can control the opening sequence of the solenoid valves 6 and the switching tasks of all the heating wires. By controlling the corresponding solenoid valves 6, the nozzles 2 are opened row by row from top to bottom to achieve layer-by-layer blowing of the snow on the roof. To improve the comprehensiveness of the purge, the effective range of each nozzle 2 is fan-shaped, the row spacing between two adjacent nozzles 2 is not greater than the radius of the sector, and the column spacing between two adjacent nozzles 2 is not greater than the length of the line segments at both ends of the arc of the sector, so that the roof surface can be covered within the effective range of the nozzles 2 arranged in an array.

[0023] Combination Figure 3 As shown, the nozzle 2 is installed and fixed at the through hole opened at the predetermined position of the aluminum alloy profile and is sealed by a rubber ring to prevent water formed by rain and snow from penetrating into the aluminum alloy profile. The air supply pipeline 5 and the solenoid valve 6 are arranged in the cavity of the aluminum alloy profile. The connecting end of the nozzle 2 and the air outlet of the air supply pipeline 5 are respectively connected to the two ends of the solenoid valve 6 through the connecting air pipe. At the same time, the power supply line 7 connecting the control cabinet 4 to the solenoid valve 6 and the heating wire and the signal line 8 connecting the control cabinet 4 to the snow amount sensor 3 are also arranged in the cavity of the aluminum alloy profile.

[0024] In summary, the innovative points of the present invention mainly include: ① High-pressure gas snow removal scheme: through air supply equipment such as an air compressor, a gas supply pipeline 5 pre-buried in the aluminum alloy profile is used to supply air to a number of nozzles 2 arranged in an array on the roof. The high-pressure gas ejected from the nozzle 2 blows off the snow on the roof; ② Heating and anti-blocking scheme: by adding a heating wire to the nozzle 2, preheating can be performed before formal snow removal to melt the ice that may exist on the nozzle 2, thereby avoiding the problem of the nozzle 2 being unable to spray due to ice blockage; ③ Layer-by-layer snow removal scheme: by adding a solenoid valve 6 to the connecting end of the nozzle 2, and using the control system in the control cabinet 4 to control the opening sequence of the solenoid valve 6, the nozzles 2 on the roof are opened row by row from top to bottom, and the snow on the roof can be blown to the ground layer by layer.

[0025] In addition, the control cabinet 4 can be powered by the municipal power supply and equipped with an additional diesel generator as a backup power supply to avoid power outages during outdoor use. The air compressor in the control cabinet 4 can be replaced with high-pressure gas from a centralized gas supply, and the high-pressure gas is shared with production, so there is no need to configure a dedicated air compressor separately.
