Device for melting icing 1 flash

The utility model relates to the field of construction, namely, devices for preventing and melting ice or snow cover on the roofs of structures, as well as in gutters and can be used to remove icicles, snow, etc. from the roof. formations.

An analysis of the state of the art in this area showed that a device for removing icicles from a cracking device is known, containing a circuit along the cornices made of pipelines with a coolant inside them made in the form of an electric heater from an electric power source (Japanese patent No. 4-2150, MKI: E04D 13/00, published on January 16, 1992).

Using a source from the mains in connection with the continuous increase in electricity tariffs implies a significant cost of this design. In addition, it requires additional measures for its isolation and safety, especially in the case of unforeseen cracks in the pipeline and water flowing into it.

A device for melting snow on the roof, containing a circuit of pipelines with a coolant, a heating device for a coolant connected to a HaipeBa source (Japan patent No. 3068295B2 5148961A, MIGi: E04D 13/00 publ. 31.07.2000).

The device is made in the form of a rather complex and cumbersome design, since it provides for the presence of a thermally insulating layer with an area equal to the roof area for directing the radiation of thermal energy upward to the floor itself, which ultimately significantly increases the cost of the structure.

A device is known for heating overhangs of a roof containing a circuit of pipelines with a heat carrier, a device for heating a heat carrier is connected MKI: E04D 13/00, 13/06 13/076

to the central heating system (USSR author certificate No. 30417, class 37 s, 11, publ. 31.05.33).

As the heat carrier, water is used from the central heating system, which is subject to freezing at low temperatures, which will require additional costs for either thawing it or maintaining it in a liquid state, which also increases the cost of the structure.

Of the known devices, the closest to the claimed is a device for melting snow on the roof of the house, containing a circuit of pipelines with at least one inlet and one outlet pipelines with a coolant, a heating medium heating device in the form of a boiler connected to a heating source, an expansion tank associated with circuit, circulation pump, control device (Japan patent No. 2840576B2 9021215A, MKI: E04D13 / 00, publ. 12.24.98).

The inability of the said device to achieve the result provided by the claimed device is caused by the use of a water coolant from a broiler tank, which is susceptible to freezing both in the case of low atmospheric temperatures and in the event of a failure of the boiler heating system, which will require additional cost for maintaining the coolant during operation in a circulating state. In addition, the presence of expensive electrical equipment as part of a control device, which also includes sensors that require the presence of heating elements such as a fan, electric lamps, etc. - raises the cost of the prototype device.

When developing the claimed design, the task was set to reduce its cost, as well as operating costs.

In solving this problem, a technical result was achieved consisting in simplifying the design and using inexpensive elemeites, which reduced its cost, as well as in using heat to heat the coolant not from an autonomously installed heating source of the heating device, but from a functioning permanently installed system, for example, central heating , which also reduced the cost of construction.

and, finally, replacing the water filler with a frost-resistant one, for example, antifreeze entailed the execution of the piping circuit closed, and the relative position of the circuit section and the heating medium heating device was adopted according to the pipe-in-pipe scheme. The described above made it possible to exclude freezing of the coolant and, therefore, significantly reduce operating costs.

The technical result is achieved in that the device for melting the icing of the cracking circuit contains a circuit of pipelines with at least one inlet and one outlet pipelines with a coolant, a heating device for a heat carrier connected to a heating source, an expansion tank connected to the circuit, a circulation pump, a control device .

New in the device is that the circuit is closed and with a joint section of the outlet and supply pipelines interacting with the heating device, the heating source of which is made in the form of a heating system, the circulation pump is connected to the circuit and to the control sensor, and frost-resistant material is used as the heat carrier .

In addition, the heating device can be made in the form of a boiler with a coil connected to the central heating system, the control device can be made in the form of a temperature sensor, and antifreeze can be used as a frost-resistant material.

The device is presented in the drawings, which depict:

FIG. 1 is a plan view of the device;

FIG. 2 is a perspective view in longitudinal section AA in FIG. 1;

FIG. 3 - diagram of the device;

The device comprises a closed circuit 1, consisting of pipelines with a coolant inside them, located, for example, along the ledges of the groove 2 and ascending to its ridge 3 and having at least one supply 4 and one outlet 5 pipe. Section 6 of the junction of pipelines 4 and 5 is located in a heating device of the type Pipe in a pipe, made in the form of a boiler 7 with a coil 8, which is connected to its heating source, filled (m in the form

heating systems, for example, central heating system 9 or boiler room, etc. Another constructive implementation of the interaction of section 6 with the heating device is possible, for example, in the form of a coil 5 wrapping a straight pipe 8 from central heating, etc.

As the coolant of circuit 1, a material with frost-resistant characteristics is used, for example, antifreeze.

The circuit is connected to the expansion tank 10 and is equipped with a circulation pump 11 connected to the control device, implemented in the form of a sensor for fixing the temperature, 1.3).

Switches 13,14, 15 are installed along the contour in the necessary places. Another arrangement of the circulation pump, for example, pos. 11 pa of figure 2, also connected to the sensor 12.

The device operates as follows.

On the structure, the structure is installed along the eaves and in the direction of the ridge, circuit 1 from the pipelines. Additional closed pipelines for heating and gutters are possible.

In the boiler tank 7, a joint section 6 of the pipeline type is installed which is welded to the outlet 5 and inlet 4 pipelines. The switch 13 accesses the antifreeze collected in the expansion tank 10 into the internal cavity of the circuit pipelines.

The sensor 12 operates within the range of atmospheric temperature fluctuations from + 5 to -15 °, where ice may melt and freeze, and turns on or off the circulation pump 11, which pumps antifreeze along a closed circuit. The latter passes through section 6, heats up in the steam jacket of the boiler created from the coil 8 heated by hot water from the central heating system 9. The heated antifreeze is discharged under the influence of circulation through the pipeline 5, subsequently contacting with the roof covering and preventing the formation of icicles, etc. snow formation, or melting already formed.

At temperatures below -15 °, ice formation stops, the sensor gives a signal to the circulation pump to stop, and with a further decrease in temperature, the antifreeze does not freeze, as a result of which the circuit is always ready to resume cirulation inside the pipelines without requiring additional heating.

With sufficiently significant fluctuations in the telegraphy, the transverse dimensions of the pipelines change (compression or tension).

In case of narrowing, part of the antifreeze is absorbed into the expansion tank, in the case of expansion of the pipe, part of the antifreeze is poured from the tank into the cavity of the piping of the circuit, ensuring its filling.

The possibility of implementing the inventive device is confirmed by the use of known means and non-deficient materials, including features presented at the level of functional generalization, with the achievement of technical results consisting in lowering the cost due to the use of central heating as heating, while reducing operating costs associated with the use of frost-resistant antifreeze , which eliminates the freezing of the circuit at low temperatures. The achievement of these results entailed a constructive change compared to the prototype of the claimed device due to the presence of the interface between the supply and outlet pipelines, the installation of a temperature sensor and a circulation pump, etc.
