Description

The invention relates to the construction, in particular, to devices for removing icicles from the roof of a building.

Known devices for removing icicles from the roof of a building can be divided into two groups: movable on the roof and installed permanently. The main disadvantages of movable devices for removing icicles from the roof of the building are the complexity and increased risk to the safety of the worker regardless of the design of the device (RF patent for the invention No. 2215857, class E04D 13/076, publ. 10.11.2003).

The indicated drawback is deprived of devices for removing icicles from the roof of a building, which are installed permanently with fastening on a wall or cornice of a building.

A device for removing icicles is known, in which a system of blocks and two-arm levers pivotally mounted on the corners of the walls of the building is provided. To the ends of the levers are attached cables stretched along the roof. The short ends of the levers are connected by additional cables to a source of mechanical disturbance, such as doors. The system of levers, blocks and cables allows the use of mechanical forces when opening doors to act on icicles. The known device provides the separation and discharge from the roof of already formed icicles due to mechanical energy (copyright certificate of the Russian Federation for invention No. 775268, class E04D 13/06, publ. 10/30/1980).

The disadvantage of this device is the involuntary removal of icicles, which can lead to injuries to people who are currently near the building.

A device for removing icicles from the overhangs of the roof of a building, including a knocking body, a cable for moving a knocking body, a system of rotary blocks and equipped with a guide fixed to the wall of the building along the roof, made in the form of a pipe and playing the role of a carrier (RF patent for the invention No. 2209905, class E04D 13/076, published on 08/10/2003).

The disadvantage of this device is the design complexity, the high probability of icing of the cable moving knocking body and the guide, which can lead to the cessation of the device.

A device is known for removing ice from the eaves of roofs of buildings and structures, including a source of mechanical impulses and an elastic element interacting with it in the form of a waveguide of metal profiles fixed along the eaves of the roof (RF patent for the invention No. 2169245, class E04D 13/00, publ. June 20, 2001).

The known device has significant disadvantages. During the operation of the building, due to the natural movements of the rafter structures or after repairing the roof, the lines of its cornice are subjected to deformation from the original position both in height and in depth. At the same time, the position of the waveguide remains stable, as it relies on the walls of the building. These non-synchronous changes can lead to the fact that icicles on the roof pass by the body of the waveguide at distances exceeding its amplitude, as a result of which the device will not fulfill its function. In addition, the disadvantages of the known device is its high cost, due to the complexity of the design, high material consumption and complexity of installation.

A device for breaking icicles is known, including sources of mechanical vibrations (vibrators) mounted on a building, made in the form of electric motors, and a waveguide interacting with it in the form of an elastic (flexible) element from, for example, a corner or other type of profile. The elastic element is fixed by one side on the edge of the roof of the building, and the other, cantilever side, contains sources of mechanical vibrations interacting with it, while the fixed side of the waveguide is configured to organize the flow of melt water along it from the protected roof. The inner side of the profile console preferably contains guides for moving along them a source of mechanical vibrations, the latter being made with the possibility of return motion along the guides (RF patent for utility model No. 855518, class E04D 13/00, published 10.01.2009).

The disadvantages of the known device are:

- the complexity of the design due to the presence of several sources, mechanical vibrations made in the form of electric motors;

- the complexity of installation due to the need to ensure sufficient friction of the impactor of the eccentric of each electric motor on the side of the waveguide console to move the source of mechanical vibrations along the guide of the waveguide;

- low reliability and durability of the device due to the presence of an open power bus, subject to oxidation during operation and the power supply to the sources of mechanical vibrations, as well as due to natural shock deformation of the waveguide guide during long-term operation, leading to a decrease in the mechanical impact of the projectile the eccentric of each electric motor on board the console of the waveguide.

Known closest to the claimed technical solution and selected as the closest analogue is a device for removing icicles from the roof of a building, including a source of mechanical vibrations mounted on the building, made in the form of an electric motor, and a flexible waveguide interacting with it, mounted on the edge of the roof of the building, according to the utility model , the waveguide consists of a housing made in the form of a flexible metal tube with an outer sealed sheath of polymer material, bearings pressed inside the tube barrels at a distance of 1000 ÷ 3000 mm from each other, and a metal cable that rotates through the internal holes of the bearings along the entire length of the tube, with one end of the cable fixed to the motor shaft and the other end of the cable with a certain tension fixed to rotate on the bearing located in the closed end cap of the waveguide body (RF patent for utility model No. 97152, class E04D 13/00, publ. 08.27.2010 - prototype).

The disadvantages of the known device are:

- the complexity of the design and installation due to the presence in the body of the waveguide pressed along the entire length of the bearings;

- low operating efficiency during operation due to the cylindrical shape of the waveguide body, the absence of thickenings on the waveguide cable and the rigid pinning of the waveguide body on the outside or inside the roof edge of the building.

- fast and small in magnitude elastic deformation of the walls of the casing 2 of the waveguide due to the shock of the metal cable 3 of the waveguide.

Turning on the device up to 10 s is enough to remove icicles 50 cm long around the entire perimeter of the roof edge of a building with a length of 250 linear meters. The vibration frequency of the body 2 of the waveguide is set taking into account the growth rate of icicles on the edge of the roof of the building and depends on the rotational-vibrational movements of the cable 3.
