Abstract

The invention discloses a device for preventing ice on an eave by the aid of an electro-thermal method, and belongs to the field of mechanical deicing. The device is used for preventing the ice generated when accumulated snow on the eave in winter is melted, so that the problem that ice falls down to injure pedestrians downstairs can be solved. The device comprises a support, an electric heating wire, a temperature sensor, an insulating heat-conduction pipe and a wire. As shown by attached graphs of abstract, the support is fixedly mounted below dripping positions of the eave, and the electric heating wire is arranged in the insulating heat-conduction pipe and is serially connected with the temperature sensor. The device has the advantages that whether the electric heating wire works or not can be controlled by the temperature sensor, so that the temperature of the outer surface of the insulating heat-conduction pipe can be indirectly controlled and constantly keeps higher than zero Celsius degree, and snow water on the eave can be prevented from being frozen to form the ice.

Description

The anti-icing slip device of electrothermal way eaves

Technical field

The present invention relates to a kind of device preventing eaves ice from slipping, belong to mechanical deicing field.The present invention is that a kind of ice that can fundamentally solve slips the device falling and hurt sb.'s feelings, the specifically anti-icing slip device of a kind of electrothermal way eaves.

Background technology

Due to the eaves of building in winter slipping because snow melting can produce ice on eaves, ice slips and to fall from eaves when temperature raises, and threatens to pedestrian downstairs, at present, normally by drawing warning line to remind people to note careful falling object from high altitude.But due to the impact of air-flow, the drop point that ice slips discretely can be distributed in certain region, likely exceeds warning line.For this reason, develop a kind of fundamentally solve ice slip produce device, necessary.Be CN201410121906.9 automatic de-icing post robot system relative to application number, it is simple that the present invention has structure, operating aspect, energy-conservation feature.

Summary of the invention

The anti-icing slip device of a kind of electrothermal way eaves of the invention is achieved by following technical proposals:

The described anti-icing slip device of a kind of electrothermal way eaves comprises: support, heating wire, temperature controller, insulating heat-conductive pipe, wire.Described support is mounted in eaves and drips the position at edge immediately below place, and the object of support is fixed insulation heat pipe.Heating wire and insulating heat-conductive pipe are nested structures, and heating wire is inner at insulating heat-conductive pipe, and has a small amount of gap between the two.Apertured object prevents heating wire from directly heating insulating heat-conductive pipe, has a negative impact to its material property.Temperature controller can detect insulating heat-conductive tube outer surface temperature, when its temperature value is at zero degree, controls heating wire work, thus the temperature of insulating heat-conductive pipe can be kept always to remain on above zero, can prevent from snowmelt runoff on eaves from freezing becoming ice slipping.

Outstanding advantages of the present invention is: the invention has rational in infrastructure, simple, and implementation method and principle are easily understood, and fundamentally can solve eaves ice and slip the problem of hurting sb.'s feelings.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the invention will be further described:

As Fig. 1, the present invention is the anti-icing slip devices of electrothermal way eaves.

As Fig. 2, heating wire and insulating heat-conductive pipe internal construction longitudinal plan.

As Fig. 3, heating wire and insulating heat-conductive pipe internal construction drawing in side sectional elevation.

1. eaves in figure, 2. insulating heat-conductive pipe, 3. support, 4. temperature controller, 5. heating wire, 6. wire, 7. water droplet, 8. support.

Detailed description of the invention is as follows:

As shown in Figure 1: on eaves 1, snow melting produces water droplet 7, and insulating heat-conductive pipe 2 is fixed on immediately below eaves 1 by support 3, and water droplet 7 can drop on above insulating heat-conductive pipe 2.Temperature controller 4 is connected with heating wire 5 by wire 6, when insulating heat-conductive pipe 2 surface temperature is less than or equal to zero degrees celsius, temperature controller 4 works by controlling heating wire 5, heating wire 5 is made to produce heat, due to the transmission effect heating insulating heat-conductive pipe 2 of heat, thus make the surface temperature of insulating heat-conductive pipe 2 remain on more than zero degrees celsius always.Therefore, the water droplet 7 that on eaves 1, accumulated snow produces can not slip by the low and icing formation ice of Yin Wendu below eaves 1.

As shown in Figure 2: insulating heat-conductive pipe 2 and heating wire 5 are nested structure, heating wire 5 is inner at insulating heat-conductive pipe 2, and fix heating wire 5 by insulating heat-conductive pipe 2 internal stent 8, thus make heating wire 5 and insulating heat-conductive pipe 2 keep certain interval, directly heat insulating heat-conductive pipe 2 when preventing heating wire 5 from working, thus the application life of device can be improved.

As shown in Figure 3: heating wire 5 is inner at insulating heat-conductive pipe 2, and both are nested, concentric.
