[0002] Greenhouses are widely used in modern agriculture for growing crops such as vegetables and flowers. However, in winter or areas with heavy snowfall, the greenhouse roof is prone to snow accumulation, resulting in excessive load on the greenhouse structure and even causing collapse, leading to economic losses. Therefore, it is of great significance to develop a steel structure of a greenhouse that can effectively prevent snow accumulation. Summary of the Utility Model

Columns are arranged at the bottom of the framework. A pressure detection device is arranged on one surface of the framework. A pressure column is arranged above the pressure detection device, and the pressure column is connected to the crossbeam. A switch is arranged on the right side of the pressure detection device. The pressure detection device and the switch are electrically connected, and the switch and the electric heating wires are electrically connected.

Specific embodiments
[0016] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Only the preferred embodiments in the description are taken as examples. All other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.
[0017] As Figures 1-4 shown, the following technical solutions are adopted in this specific embodiment: It includes a shed top 1, on the back surface of the shed top 1, electric heating wires 16 are uniformly fixed, and there are multiple groups of horizontally connected cross beams 15 between the shed tops 1. Drainage ditches 11 are provided on both sides of the shed top 1. The frame 2 is fixedly connected to the bottom of the drainage ditch 11 through multiple groups of secondary connection columns 25 on both sides. The frame 2 is also fixedly connected to the cross beams 15 at the front and rear ends of the shed top 1 through multiple groups of main connection columns 21. An upright column 24 is fixedly provided at the bottom of the frame 2. And a pressure detection device 22 is provided on one surface of the frame 2. Above the pressure detection device 22, there is a pressure column 26, and the pressure column 26 is connected to the cross beam 15. A switch 23 is provided on the right side of the pressure detection device 22. The pressure detection device 22, the switch 23 and the electric heating wire 16 are electrically connected. The shed top 1 is a spire type composed of two inclined plates. The pressure detection device 22 is located below the roof ridge. Multiple groups of partition pieces 14 are uniformly fixed on the surface of the shed top 1. The drainage ditch 11 has a slope, and a drainage outlet 12 is provided on the lower side of the drainage ditch 11. A drain pipe 13 is provided at the bottom of the drainage outlet 12, and a heat preservation pad is wrapped on the surface of the drain pipe 13.
[0018] When using the present utility model, when there is no snow accumulation, the pressure column 26 applies a pressure to the pressure detection device 22 that does not exceed a predetermined value. When there is snow accumulation on the shed roof 1, the partition piece 14 will partition the snow accumulation to promote the sliding of the snow accumulation, preventing the snow accumulation from piling up on the surface of the shed roof 1. At this time, the pressure column 26 applies a pressure to the pressure detection device 22 that exceeds the predetermined value, and the pressure detection device 22 sends an electrical signal to the switch 23. The switch 23 activates the heating wire 16, and the heating wire 16 generates heat to melt the snow accumulation on the surface of the shed roof 1. The water generated by the melting flows along the shed roof 1 to both sides and into the drainage ditch 11, and is discharged from the drain pipe 13. When the snow accumulation melts and the pressure applied by the pressure column 26 to the pressure detection device 22 is less than the predetermined value, the pressure detection device 22 sends an electrical signal to the switch 23 again to turn off the heating wire 16.
[0019] Compared with the prior art, the beneficial effects of the present specific embodiment are as follows:
[0020] 1. By providing a heating wire and a pressure detection device, the snow accumulation is prevented from collapsing the greenhouse due to excessive pressure.
[0021] 2. By providing a surface partition piece on the shed roof, the snow accumulation can be partitioned and the sliding of the snow accumulation can be promoted.
[0022] For those skilled in the art, they can modify the technical solutions recorded in the foregoing embodiments and perform equivalent replacements of some technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
