Description

Technical Field

[0001] This utility model relates to the field of rainwater hopper technology, specifically a self-regulating electric heating siphon rainwater hopper. Background Technology

[0002] A siphon rainwater hopper is a device used to collect and discharge rainwater. It is widely used in the roof drainage systems of buildings. Its working principle is based on the siphon phenomenon, that is, under certain conditions, liquid can form a continuous flow in the pipe through the action of gravity and air pressure.

[0003] However, when existing siphon rainwater hoppers are used in winter, snowmelt can also enter the siphon rainwater hopper through the roof and eaves gutters, and then enter the drainage system. With the repeated changes in temperature, the snowmelt will freeze inside the drainage system, which will block the roof's rainwater drainage system, causing the drainage function to be lost, increasing the roof load, and posing a safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a self-regulating, electrically heated siphon rainwater hopper, which has the advantage of preventing blockages. It solves the problem that in winter, snowmelt enters the siphon rainwater hopper through the roof and eaves gutters, and then enters the drainage system. As the temperature fluctuates, the snowmelt freezes inside the drainage system, blocking the roof's rainwater drainage system, causing a loss of drainage function, increasing the roof load, and posing a safety hazard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-regulating electric heating siphon rainwater hopper, comprising a siphon rainwater hopper body, wherein the siphon rainwater hopper body is provided with a heating and heat preservation mechanism;

[0006] The heating and insulation mechanism includes a side self-regulating electric heating cable fixedly installed on the side surface of the siphon rainwater hopper body, a bottom self-regulating electric heating cable fixedly installed at the bottom of the siphon rainwater hopper body, an insulation layer fixedly installed on the outer surface of the siphon rainwater hopper body, a flow guide shroud fixedly installed at the top of the siphon rainwater hopper body, and a siphon rainwater hopper outlet pipe fixedly installed at the bottom of the siphon rainwater hopper body.

[0007] Furthermore, a protective cover is fixedly installed on the outer surface of the insulation layer, and a connecting bolt is threaded to the bottom of the protective cover. The connecting bolt is threaded to the surface of the siphon rainwater hopper body.

[0008] Furthermore, the surface of the flow guide is threaded with fixing bolts, which are threadedly connected to the surface of the siphon rainwater hopper body.

[0009] Furthermore, a connecting pressure ring is fixedly installed on the surface of the flow guide, and a sealing rubber gasket is fixedly installed on the lower surface of the connecting pressure ring, and the sealing rubber gasket is in close contact with the surface of the siphon rainwater hopper body.

[0010] Furthermore, a connecting wire is fixedly installed at the bottom of the protective cover, and the side self-regulating electric heating cable and the bottom self-regulating electric heating cable are both connected to the connecting wire.

[0011] Furthermore, the side self-regulating electric heating cable and the bottom self-regulating electric heating cable are evenly distributed on the side surface and bottom surface of the siphon rainwater hopper body.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This self-regulating electrically heated siphon rainwater hopper features an insulation layer, side self-regulating electric heating cables, and bottom self-regulating electric heating cables on the hopper body. This heating effectively prevents snowmelt from freezing inside the hopper, ensuring unobstructed drainage and maintaining the normal drainage function of the roof drainage system. It also eliminates safety hazards and solves the problem of existing siphon rainwater hoppers in winter where snowmelt enters the hopper through the roof and eaves gutters, subsequently entering the drainage system. With fluctuating temperatures, this snowmelt freezes inside the drainage system, blocking the roof's rainwater drainage system, causing drainage failure, increasing roof load, and posing safety risks.
