Description

Technical Field

[0001] This utility model relates to the field of fully automatic or semi-automatic heating of outdoor carports, specifically to an outdoor membrane structure carport that prevents snow accumulation. Background Technology

[0002] With the improvement of residents' living standards, the number of cars in my country is increasing, and the demand for outdoor parking garages (sheds) is growing. Among them, membrane structure outdoor carports account for a large proportion of outdoor carports.

[0003] A membrane structure carport is an architectural form that uses high-strength steel as a frame and covers it with polyester or polycarbonate membrane as a roof. Compared with traditional carports, it has the following structural advantages: 1) The frame structure is lightweight, which can reduce the amount of building materials used and is more environmentally friendly; 2) The membrane material has good plasticity, which can realize large-area curved surface construction, making it beautiful and elegant.

[0004] Because membrane structure materials are lightweight, carports are subject to relatively low loads. Therefore, they are generally designed as inverted "L" shapes. This type of structure leaves no obstructions in front of the carport, making it easier for cars to enter and exit, and requiring less skill from the driver when reversing into the parking space. As a result, outdoor membrane structure carports have been widely promoted.

[0005] The inverted L-shaped cantilever structure has poor stress distribution. The steel beams on the garage columns and roof (near the columns) experience large moments. If there is an additional gravity load on the roof, the stress on the steel structure will deteriorate rapidly, easily leading to accidents involving vehicle damage and personal injury. The additional load on the roof typically comes from snow accumulation. In cold, snowy weather, if the snow and ice cannot melt in time, the increasing snow thickness can easily exceed the roof's design load-bearing capacity, causing the roof to collapse. Utility Model Content

[0006] The main objective of this invention is to provide an outdoor membrane structure carport that prevents snow accumulation, thereby effectively solving the problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An outdoor membrane structure carport designed to prevent snow accumulation, wherein a power live wire and a power neutral wire are provided below the top surface of the carport, a power live wire bypass is provided on the power live wire, and a power live wire bypass manual switch is provided on the power live wire bypass.

[0009] Several sets of parallel heating resistance wires are provided between the power supply live wire and the power supply neutral wire.

[0011] As a preferred technical solution of this utility model: the power supply live wire is provided with a live wire main circuit manual switch and a temperature control switch, and the live wire bypass is connected in parallel at both ends of the live wire main circuit manual switch and the temperature control switch.

[0012] As a preferred technical solution of this utility model: the inner core of the heating resistance wire is a resistance heating conductor that heats up when energized, and the outer surface of the heating resistance wire is an insulating and thermally conductive silicone.

[0013] As a preferred technical solution of this utility model: the heating resistance wire is fixed to the bottom of the carport roof by cable ties or tape.

[0014] This utility model provides an outdoor membrane structure carport for preventing snow accumulation, which has the following beneficial effects: By laying heating resistance wires on the lower part of the carport roof, the roof is heated, allowing the snow on the roof to melt in time, effectively eliminating or reducing the accumulation of ice and snow on the roof during low-temperature snowfall, effectively reducing the gravitational load on the roof, and preventing the garage roof from collapsing under the weight of snow, causing personal and property damage; the power supply is divided into a main circuit and a bypass circuit, with a temperature control switch installed on the main circuit and a manual switch installed on the bypass circuit, which can realize both manual and automatic control modes simultaneously, providing dual protection; the heating resistance wires are installed in parallel between the live wire and the neutral wire, and the number of heating wires can be increased or decreased according to the length of the garage, making it highly adaptable.

Detailed Implementation

[0020] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-4 As shown, an outdoor membrane structure carport for snow protection is provided with a power live wire 1 and a power neutral wire 2 below the top surface of the carport. A power live wire bypass 5 is provided on the power live wire 1, and a power live wire bypass manual switch 6 is provided on the power live wire bypass 5.

[0022] Several sets of parallel heating resistance wires 7 are provided between the power live wire 1 and the power neutral wire 2.

[0023] The power supply live wire 1 is equipped with a live wire main circuit manual switch 3 and a temperature control switch 4. The live wire bypass 5 is connected in parallel across the live wire main circuit manual switch 3 and temperature control switch 4. With this configuration, it can be controlled manually or by temperature.

[0024] Temperature control switch 4 automatically closes at low temperatures and automatically opens at high temperatures.

[0025] Temperature control switch 4 can be an adjustable temperature control switch. When the temperature is low, the temperature switch is in a normally closed state. When the temperature exceeds the set temperature, the switch will activate and disconnect the circuit.

[0026] The inner core of the heating resistance wire 7 is a resistive heating conductor 71. When an external power supply is connected to both sides of the metal heating resistor, the resistance wire will automatically heat up.

[0027] The heating resistance wire 7 is covered with insulating and thermally conductive silicone 72, which can protect the internal resistance and prevent leakage. At the same time, the material has good thermal conductivity, which can conduct the heat generated by the heating resistance in time and transfer it to the garage roof through heat conduction to melt the snow on the roof.

[0028] The number of heating resistance wires (7 sets) is determined based on the length of the garage.

[0029] The heating resistance wire 7 is fixed to the bottom of the carport roof using cable ties or tape.

[0030] Specifically, the aforementioned snow-proof outdoor membrane structure carport is implemented in the following ways:

[0031] Under normal circumstances, there are the following three states:

[0032] (1) In non-rainy or snowy weather, both the main power line manual switch 3 and the bypass manual switch 6 are open, and the snow prevention system does not work.

[0033] (2) In low-temperature snowy weather, the main power line manual switch 3 is closed, the bypass manual switch 6 is open, and the temperature control switch 4 is set to power on below 0℃ and power off above 0℃. This enables the intelligent automatic start and stop of the anti-water accumulation system in snowy weather.

[0034] (3) In low temperature and snowy weather, the main power line manual switch 3 is in the off state. Based on the thickness of the accumulated ice and snow and the weather forecast, the bypass manual switch 6 is manually turned off and the power is turned on to melt the snow from time to time.

[0035] This operating mode is the most energy-efficient, but requires a large amount of manual maintenance and is generally used in cold weather with little snowfall.

[0036] The above specific embodiments are used to explain and illustrate the present utility model, and are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made to the present utility model within the spirit and protection scope of the claims shall fall within the protection scope of the present utility model.
