RU2829772C1 - Method for pneumatic removal of icicles from roofs - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: invention relates to a method for removing icicles from a building roof. Method of removing icicles from roofs using flexible tubular containers (6), expanding under action of air injection and acting on hanging ice icicles, consists in the fact that flexible tubular containers (6) are attached to supporting cable (3), which is fixed on the roof, at that cable tension sensor (4) is attached to cable (3), which transmits a signal to control unit (8) of air pump (7).

EFFECT: reduction of energy and material costs for operation of the roof.

Description

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

A device from patent RU 2002129214 A is known, consisting of a pipe connected to the heating system and located at an angle of natural drainage, and two valves, allowing for the timely removal of snow and ice formations.

The disadvantage of this device is that it wastes significantly more heat than is necessary to melt the entire volume of overhanging ice and icicles, because the water, not having time to melt the icicles, flows from them onto the ground, without giving them all of its energy.

The closest device to the claimed one is described in patent RU 2509190 C2, in which a pneumatic hose installed around the perimeter of the building under the roof is used to remove ice and icicles from the roofs of buildings and structures, which removes icicles by expanding under the influence of forced air.

The disadvantage of the known device compared to the declared one is the greater structural complexity and cost of installation and operation.

The technical result of the invention is to simplify the design and reduce energy and material costs for roof operation.

The technical result is achieved by the fact that flexible tubular containers are installed in places where icicles form and are cleaned by inflating and deflating them with air.

Fig. 1 is a diagram of a device for implementing the proposed method of pneumatically removing icicles from a roof (1), comprising roof fastenings (2), a supporting cable (3) installed above the edge of the roof (1) for fastening a flexible tubular container (6), a cable tension sensor (4), fastenings (5) of the flexible tubular container (6) to the cable (3), a pump (7) and a control unit (8), states: a) before icing of the flexible tubular container, b) after its icing, c) after removing the icing.

Flexible tubular air containers (6) are made with an air-tight layer, and the supporting cable (3) is attached to the roof using fasteners (5) that can move along it.

The control unit (8) automatically switches the air pump (7) on/off for inflation and deflation depending on the readings of the support cable tension sensor (4).

The device for pneumatic removal of icicles from roofs works as follows. When the flexible tubular container (6) is iced, the cable (3) sags and the cable tension sensor (4) sends a signal to the control unit (8), which switches on the pump (7), the flexible tubular container (6) inflates and the ice falls off it, the sagging of the supporting cable (3) disappears. Then the control unit (8) switches the pump to pumping air out of the flexible tubular container (6) until it returns to its original state.

The device for automatic removal of ice from roofs at any time of the day or night is based on the use of known materials, devices, equipment and technical solutions, and is of great economic and national economic importance for significantly reducing the incidence of injuries from falling icicles and the labor costs of removing them.

Example #1

A method of pneumatically removing icicles on a 30 m long section of a roof. A flexible inflatable hose 30 m long is installed on a supporting cable under the lower edge of the roof. When it sags under the weight of the ice, it pulls the cable to which it is attached and its tension sensor is triggered. The control unit turns on the inflation of the hose and the ice falls off it, the sagging of the cable disappears and the pump deflates the hose to its original state.

Example #2

A method of pneumatically removing icicles on a 60 m long section of a roof. Flexible inflatable hoses 30 m long are installed under the lower edge of the roof, connected to each other on a single cable and a tension sensor or on their own supporting cables and tension sensors. When they are triggered, the inflation of the corresponding hose is turned on and the ice falls off it, the sagging of the cable disappears and the control unit turns on the pump to deflate the hose to its original state.
