Description

FIELD OF TECHNOLOGY

The utility model relates to public utilities and can be used, in particular, to prevent the accumulation of snow and the formation of ice on sidewalks and roads.

BACKGROUND

Known (RF patent 2419704) is a method of cleaning roads, which consists in equipping a heated area, at the surface of which heating pipes are laid with a coolant circulating over them. Heating of the surface of the site and melting of the snow located on it are carried out due to the heat energy generated by the heat pump heat and cold supply system. Atmospheric air taken directly from the heated area was used as a source of low potential heat.

The disadvantages of this solution are the inconvenience associated with the need to expect accumulation of sufficient snow for the use of cleaning and loading equipment, the relatively high energy costs associated with the need to load snow onto a vehicle and deliver it to a heated area, environmental pollution with exhaust gases during loading and transportation of snow , as well as the relatively large melting time of a large amount of accumulated snow.

It is known (RF patent 156102) a multilayer coating for heating surfaces, containing a tubular coolant conductor made of flexible material, installed between the lower and upper layers made of flexible material, the upper coating layer is made of crumb rubber with a polymer binder. This coating is proposed to prevent the formation of snowdrifts, icicles, to prevent icing of sidewalks, landings, roofs of buildings.

The disadvantage of this solution is the need to use several layers of coating, which significantly increases the cost of the solution and complicates its use in conditions of constant intense mechanical load (sidewalks, roads).

Known (RF patent 2480554) is a method of removing snow from the roadway, namely, that the thermal cable is straightly laid on the surface of the dividing strip of the roadway and cover the end and the beginning of it with a shield, between which and the thermal cable form a gap, while part of the shield is extended beyond the edge of the snow snowdrift and connect the thermal cable to the current source. The heat coming from the thermal cable melts the snow.

The disadvantage of this solution is the narrow scope - melting snow falling on the roadway, and the need to use an electric cable, which is associated with significant costs and is not safe.

Known (RF patent 2267237) adjustable cable heater. According to this solution, the adjustable cable heater comprises a regulator, connecting wires, connecting couplings and a heating cable, the ends of which are connected to the first ends of the connecting wires through the connecting couplings, and the second ends of the connecting wires are connected to the regulator. The heating cable contains an additional core of electrically conductive material, and the cable sheath is made of a material with temperature-dependent electrophysical properties. The ends of the additional core are connected to the regulator. It is proposed to embed this device in building structures and use it for heating rooms, surfaces of sidewalks, stadiums, roofs of buildings, etc.

The disadvantage of this solution is the need to use an electric cable, which is associated with significant costs and is not safe.

It is known (RF patent 224556) a device for protecting the coating of airfields, roads and bridges against icing, including a tubular register located in the coating sheet, a regenerative heat exchanger, a water well equipped with a submersible pump and water conduits, a “cold” injection well located downstream groundwater relative to the water well, and equipped with a "warm" injection well located in a straight line with the "cold" injection and water wells and upstream groundwater relative to the water well at a distance equal to the path traveled by ground water for six months, while the “cold” injection well is located relative to the water well at a distance of not less than the sum of the radii of their influence.

The disadvantage of this solution is the dependence of the system on the continuous power supply of the water intake and injection wells: if they stop at low air temperatures, the entire system becomes unusable, and continuously circulating water freezes. In addition, this solution is energy-consuming, since it requires the use of powerful pumping systems.

Known (RF patent 2300611) is a method of preventing the formation of snow, icicles and icing protection, comprising a gas-liquid and / or water-liquid system of heat exchangers, a circulation pump and a system of heating plastic pipes, which is laid in all places where necessary, the pipes are filled with non-freezing liquid, which continuously circulates along the system circuit under the influence of a circulation pump and passes through a gas-liquid and / or water-liquid system of heat exchangers, the heating of which is provided I am due to their location in the ventilation systems of buildings, underground structures or in the flue gas pipes of boiler rooms or by location in the heating system and / or hot water supply.

The disadvantage of this solution is the need to use a complex of complex expensive equipment, as well as the use of expensive and not environmentally friendly non-freezing liquid.

The prototype is a method and device for processing snow at the place of its precipitation (RF patent 2096554), which consists in melting the snow and completely evaporating the formed moisture using a heat source passing under the cover of the carriageway of city roads and sidewalks, using atmospheric air as a heat carrier which is heated to a temperature of 99-105 ° C and pass it under the coating.

The disadvantages of the prototype are: 1) the method is aimed at melting already precipitated snow, in connection with which there is a requirement for the temperature of the coolant - about 100 degrees Celsius; 2) accordingly, the heat source for implementing this method should be powerful enough, 3) while, according to the description of RU 2096554, it is proposed to use rock heat at a sufficient depth as a heat source, for which it is proposed to drill a well of sufficient depth.

IMPLEMENTATION OF A USEFUL MODEL

The device (see Fig. 1) includes at least one plastic pipe (2) laid directly under the paving slabs (1), connected to at least one air blower (3) that delivers warm air from underground communication collectors ( four). It can be used, for example, a typical corrugated pipe made of polyvinyl chloride (PVC), used in everyday life as a drainage pipe, with a diameter of, for example, about 50-60 mm. The pipe is laid in the ground (5) directly under the paving slabs, and provided with holes with a diameter of not more than 0.5 mm. This hole size is optimal, because it provides efficient heat transfer, and at the same time, the probability of groundwater penetration into the pipe cavity is minimal. One end of the pipe is closed by a plug (6), the other end of the pipe is connected to an air blower equipped with, for example, an electric motor, which supplies air to the plastic pipe from the communication manifold connected to the blower. Communication collectors, laid for, for example, providing electricity, water, etc., in typical cases, laid at a depth of 1.5 to 3 meters. Due to the depth and technological purpose (ensuring the passage of electrification or water supply paths), the air in the collectors is always a positive temperature, about 10-20 degrees Celsius.

The device is operated as follows. If it becomes necessary to melt snow and / or prevent ice formation on the surface of paving slabs, the air blower engine is turned on and warm air is pumped from the internal cavity of the communication manifold connected to the air blower into the internal cavity of the pipe laid directly under the paving slabs. The pipe is equipped with openings, thanks to which heat exchange with paving slabs is as achievable as possible. Thanks to heat transfer, paving slabs constantly receive heat sufficient to melt snow and prevent the formation of ice on the surface of the pavement. If necessary, it is possible to additionally use heating elements in places of air supply.

Depending on the size of the sidewalk section to be affected by the claimed device, various options for laying the device pipe and the shape of this pipe are possible. In the simplest case, the pipe can be laid straight under the paving slabs and include a sloping segment attached to the air blower. Alternatively, if necessary, the pipe can be laid under the tile in the thickness of the soil in a wavy, zigzags, etc. - an example of a possible stacking is shown in FIG. 2.

Various modes of operation of the claimed device are possible. For example, the device can be operated in accordance with short-term weather forecasts - during the entire period of the expected precipitation in the form of snow or wet snow or snow with rain, etc. Alternatively, the inventive device may be further provided with at least one snow sensor (7) attached to the air blower, and starting the operation of the inventive device when snow appears on the surface of the sidewalk.

Similarly, the operation of the claimed device for melting snow and / or preventing the formation of ice on the road surface.
