Description

Rainwater pipe anti-icing clogging device

Technical Field

The utility model relates to a downspout technical field, especially a downspout anti-icing clog device.

Background

The rain pipe is a vertical pipe for guiding water in the eaves gutter to the ground, and is also called a downpipe, which is also called a drain pipe, a sewer pipe, a downpipe and the like. The rainwater pipe is made of PVC, aluminum alloy, resin, copper and the like, the price of copper is high, and the rainwater pipe made of PVC is generally used in the market. PVC is a high molecular material using a chlorine atom instead of a hydrogen atom in polyethylene, has poor stability to light and heat, is decomposed to generate hydrogen chloride at 100 ℃ or by long-term sunlight exposure, and autocatalytically decomposes to cause discoloration and aging. In cold areas, the temperature is mostly lower than the freezing point at night, when the roof ice and snow with higher temperature melt into water and are guided to the ground through the rainwater pipe in the daytime, a layer of water drops can be hung on the inner wall of the pipe, and a layer of thin ice is arranged on the inner wall of the pipe at night, so that the flow guide section of the inner wall of the pipe is smaller and smaller when the roof ice and snow melt into water, the whole rainwater pipe can be blocked by the ice after a long time, the ice layer can be melted after the whole temperature rises when the roof ice and snow melt in the pipe in spring, and the ice columns in.

The existing rain pipe has the following problems:

1) the rainwater pipe can not guide the flow after being blocked, and the ice and snow load of the roof of the building is increased.

2) After the rain pipe is plugged, rainwater and water formed by snow gather on the roof and are frozen into ice, the service performance of the heat-insulating and waterproof material of the roof is seriously influenced, and the heat-insulating and waterproof material is aged in advance, is brittle and hard and even breaks.

3) The expansion of ice in the rainwater pipe easily causes the freezing expansion of the PVC rainwater pipe, even the frost crack and the frost damage of the rainwater pipe.

4) When the rainwater pipe is frozen to rise and fall or the residual ice in the rainwater pipe which is not frozen and damaged at a high position melts and falls after the temperature rises in spring, personal injury safety accidents are easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a downspout anti-icing blocking device, the device can detach the interior incomplete ice of downspout, prevents effectively that the downspout from producing the shutoff.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

the utility model provides a downspout anti-icing jam device, includes the downspout, takes insulating layer resistance wire and buries the wall threading pipe, takes insulating layer resistance wire to wear to locate in the downspout, takes insulating layer resistance wire both ends to wear out the downspout and get into respectively after burying wall threading pipe and insert the power and form the return circuit.

Compared with the prior art, the beneficial effects of the utility model are that: the heating through the resistance wire melts the ice in the rainwater pipe into water, and the water is discharged along the rainwater pipe, so that the problems of ice blockage, frost crack of the pipe body and personal safety caused by the rainwater pipe are prevented, and the electric rainwater pipe is simple in structure and convenient to use.

Furthermore, the embedded wall type electric heating wire fixing device further comprises a top communicating pipe and a bottom communicating pipe, the upper end of the resistance wire with the insulating layer enters the embedded wall threading pipe through the top communicating pipe, and the lower end of the resistance wire with the insulating layer enters the embedded wall threading pipe through the bottom communicating pipe.

Furthermore, the top end of the rainwater pipe is communicated with a drainage rain hole on the roof plate, and the rainwater pipe is fixed on the surface of the wall body through the wall-buried support.

Further, the power supply is 220V alternating current.

Drawings

Fig. 1 is a schematic structural view of an anti-icing and anti-blocking device for a storm sewer according to an embodiment of the present invention.

Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, the rainwater pipe anti-icing and anti-blocking device comprises a rainwater pipe 1, a resistance wire 2 with an insulating layer and a wall-buried threading pipe 3, wherein the resistance wire 2 with the insulating layer is arranged in the rainwater pipe 1 in a penetrating manner, and two ends of the resistance wire 2 with the insulating layer penetrate through the rainwater pipe 1 and then respectively enter the wall-buried threading pipe 3 to be connected with a power supply 4 to form a loop. The ice in the rainwater pipe 1 is melted into water through the heating of the resistance wire 3 and is discharged, and the ice in the rainwater pipe 1 is effectively prevented from being blocked.

The rainwater pipe anti-icing and anti-blocking device further comprises a top communicating pipe 5 and a bottom communicating pipe 6, the upper end of the resistance wire 2 with the insulating layer enters the wall-buried threading pipe 3 through the top communicating pipe 5, and the lower end of the resistance wire 2 with the insulating layer enters the wall-buried threading pipe 3 through the bottom communicating pipe 6.

The top end of the rain pipe 1 is communicated with a drainage rain hole 7 on a roof slab, and the rain pipe is fixed on the surface of a wall body through a wall-buried bracket 8.

Preferably, power 4 is 220V alternating current, takes insulating layer resistance wire 2 both ends to get into behind the wall-buried threading pipe 3 and introduce the room in and link to each other with the power supply terminal respectively, when not needing to heat insulating layer resistance wire 2, the disconnection power 4 can, when needing to heat insulating layer resistance wire 2, the switch-on power 4 can, plug-and-play, simple and convenient.

Preferably, the resistance wire in the resistance wire 2 with the insulating layer is made of nickel complex gold material.
