Description

The present invention relates to the field of public utilities and, in particular, can be used to heat pipes for water and heat supply in winter, during periods of emergency at central heating stations.

There is a known problem of freezing and subsequent rupture of water pipes and heating radiators during periods of emergency in winter, in the central heating system. In this case, even after eliminating the causes of the accident at the central heating center or on highways, it is necessary to carry out laborious work to replace the destroyed pipes and radiators in the houses and industrial premises serviced by this heat supply system,

Also, at night, during periods of severe frost in winter, water consumption in pipes and in the sewage system sharply decreases. This is fraught with freezing of sewage and water supply systems in residential buildings. To exclude a similar situation at night, hot water is included for heating the pipes, which leads to its excessive consumption.

It is known "Device to prevent freezing of the pipeline", containing a camera installed in the pipe with a heat-sensitive element, a drain hole and a valve interacting with it, the camera is installed inside the pipe in the transverse direction and is provided with holes in the side walls for the passage of the transported fluid, and the heat-sensitive element is made in the form a rod made of a material with a shape memory effect that ensures a change in the axial length of the rod with a change in the temperature of the pumped medium, one end of which fixed in the pipe, and at the opposite end of the shaft a valve is installed that closes the drain hole made in the pipe, in addition, titanium nickelide alloy is used as a material with a shape memory effect, see RF patent No. 116599, F17D 1/05 of December 13, 2010 .

The closest in technical essence to the claimed invention is an electric heater containing a textile with an internal electric heater, designed to heat the room or, in another embodiment, used as a plaid or blanket, see the brochure "Center for unique products", No. 527, 2008 p. 18.

However, the known electric heater due to its shape cannot be used to heat pipes, radiators and other elements of the water and heat supply system during emergency shutdowns of heat supply and due to the inadequacy of the design of the electric heater for heating lengthy and curly sections of pipes and radiators due to the impossibility fixing them and ensuring reliable contact with the elements of water and heat supply and the difficulties of connecting them to the power grid.

The aim of the present invention is to achieve a technical result to ensure tight and reliable contact of the electric heater with elements of water and heat supply in all areas of the water and heat supply system, ranging from basement to residential and industrial premises.

In the first embodiment, the indicated technical result is ensured by the fact that in the known heater containing a textile fabric with an internal electric thermocouple, it is proposed to make the coupling in the form of a set of cuffs successively placed on pipes or radiators, each of which contains an electrical outlet mounted parallel to the supply wire mounted on the outside cuffs, at the input of the wire into the cuff, while the extreme cuff 1 of the set is connected via a wire with an electric plug 4 to the external electric Roset and each subsequent cuff serves to connect the plug to its outlet each succeeding cuff 3 and set on the edges of the cuff fixing elements made, for example, from Velcro fabric.

In the second embodiment, the indicated technical result is ensured by the fact that in the electric heater containing a textile sheet with an internal electric conductor, it is proposed to additionally place a flexible tube with distilled water adjacent to the electric thermocouple inside the coupling itself in the form of an extended elastic rectangular plate, the length of which is several times greater than it width, and along the long sides of the coupling it is proposed to place fasteners made, for example, in the form of velcro fabric.

The invention is illustrated in graphic materials.

Figure 1 shows the first embodiment of the coupling, Figure 2 shows the working layout of the cuffs of the first variant on the water and heat supply pipe, Figure 3 shows the second embodiment of the cuff, Figure 4 shows the working layout of the cuff of the second variant on the water pipe - and heat supply.

In the first embodiment, in Fig.1, 2, the coupling for heating the pipes and pipes for water and heat supply contains:

1. cuff made of elastic plate;

2. internal electric thermocouple cuff 1;

3. power outlet cuff 1;

4. electric plug;

5. cuff fastening elements 1;

6. water and heat supply pipe.

In the second embodiment, in figure 3, 4, the coupling for heating the pipes and pipes for water and heat supply contains:

1. cuff made of elastic plate;

2. internal electric thermocouple;

3. power outlet cuff 1;

4. an electric plug for connection to the power supply network;

5. fasteners;

6. water and heat supply pipe;

7. A tube of distilled water.

In the first embodiment, the coupling for heating pipes for water and heat supply consists of a set of cuffs 1 made in the form of elastic plates containing internal electrical thermocouples 2, the input ends of which are connected via an electric plug 4 to electrical outlets 3 connected in parallel with the electric circuit.

The power sockets 3 are located on the outer sides of the cuffs 1, while the extreme cuff 1 of the kit is connected via an electric plug 4 to the external power supply, and each subsequent cuff is connected to the power socket 3 of the previous cuff 1, fastening elements 5 are made along the long sides of the cuffs 1, made for example , made of velcro fabric.

In the second embodiment, the coupling for heating water and heat supply pipes is made in the form of an extended elastic plate 1, the length of which is several times greater than its width, a tube 3 with distilled water is placed inside the plate 1, adjacent to an internal electric thermoelement 2, connected by a wire to an electric plug 4 on it the end with an external electrical network, and along the edges of the long side of the elastic plate 1 there are fastening elements 5 made, for example, of velcro fabric.

In this embodiment, the size of the heating thermocouple 2 may be short, because heating of water and heat supply elements will be carried out by heated distilled water in a tube 3.

Given that the design of the water and heat supply systems can have bizarre and extended forms, therefore, the couplings should be completed in groups in which the lengths of the plates 1 can have different sizes, i.e. multiple, 2, 3, 4 or more times their width.

The multiplicity of the excess of length over the width of the coupling is due to the need to wind long pipes or overall radiators.

With couplings work as follows.

First option

At the time of an emergency in the water and heat supply system, which is determined by the pipes and radiators cooling in residential buildings and premises, elastic cuffs 1 are sequentially put on pipes 6 and radiators and fixed by means of fastening elements 5.

The cuff 1 closest to the external electrical network is connected to an external electrical outlet by means of a wire with an electric plug 4. A wire with a plug 4 of the next sleeve 1 is connected to an electrical outlet 3 of the first sleeve 1. In a similar manner, the third sleeve 1 is connected to the second sleeve, etc. The next several cuffs 1 are put on another section of the water and water supply pipe and connected in the same way. Thus, several cuffs 1 are located on the pipes and radiators, the electrical thermocouples 2 of which begin to heat them. This allows you to ensure long-term maintenance of the water temperature in the pipes and in the radiators connected to it above the freezing point.

Given that the cuffs 1 are connected to each other in parallel, the current flowing through the electric heaters 2 of these cuffs 1 is reduced, therefore, to maintain a high heating temperature, it is recommended that the number of cuffs connected together be from three to five.

In the second embodiment, the elastic plates 1 for different pipes are made of different lengths, exceeding their width by 2, 3, 4 or more times. At the same time, during an emergency at the thermal point, the plates 1 are wound along the length of the pipes and, through the fastening elements 5, are securely fixed to them.

The electric heater 2 through its plug 3 is connected to the nearest external power supply. When the current flows through the electric heater 2, its temperature rises and heats distilled water in the adjacent tube 3. The distilled water in the tube 3, in turn, heats the water and heat supply pipes, maintaining their temperature above the freezing point of water.

At the time of an emergency, utilities first of all install couplings on the underwater and branch lines of water and heat supply and in rooms close to the outer sides of buildings and structures, for example, in basements and entrances. Then the couplings are installed directly in the living quarters both by the utilities and by the residents themselves.

Thus, during the entire period of emergency at the heat station, in all rooms with a water and heat supply system, water is maintained in a non-freezing state, which eliminates the rupture of pipes and radiators and their subsequent replacement.

After the emergency, the couplings are removed and stored until the next emergency.

The present invention is new, previously unknown, which indicates its compliance with the patentability criterion - novelty.

A coupling for heating pipes for water and heat supply can be made in any workshop from finished goods and improvised means, which indicates its compliance with the patentability criterion - industrial applicability.
