Description

FIELD OF TECHNOLOGY

The utility model relates to the field of construction, in particular to a device for dumping ice and icicles from the roof peaks of various buildings.

BACKGROUND

The prior art device for removing icicles from the roof of a building roof, disclosed in RU 110790 U1, publ. 11/27/2011. A device for removing icicles from the roof of a building roof, including a roof, the surface of which is de-iced with a strip along the lower edge of the roof, the width of the strip depending on the climatic zone and the slope of the roof is determined by a value from 0.1 m to 2.5 m, while the strip the coating can be applied with an overflow relative to the roof by a droop of at least 2 cm down from its lower edge, and the angle between the roof plane and the overflow does not exceed a value of 180 °, characterized in that part of the anti-icing coating protruding beyond the edge of the roof, made of a material with the property of flexibility and elasticity, at least at the temperatures of formation of ice and icicles, while on the inside of the overhanging part of the coating, an interacting source of mechanical vibrations is mounted cantileverly mounted on the building, made in the form a shaft with eccentrics and an electric motor installed in the under-roof space of the building roof and equipped with a soft start and braking system.

The disadvantage of the device disclosed above is primarily that this device itself is already potentially dangerous, since it has a large weight and rotates a certain load, which affects the imbalance of the device axis, which in turn will transmit vibrations to the console fixtures to the building, from which there is a high probability of the device breaking from the first unreliable fastener, which will lead to a chain reaction of the failure of the remaining fasteners due to the separation of the structure and its large weight, in the future will lead to the fall of the whole uctions. Secondly, it is that in most buildings with an inclined roof, the floor in the attic is approximately at the peak and it is not possible to install any engine with a belt drive to the device under the peak. In the third turn, these electric motors suitable in power for the rotation of the device need high-voltage power, which in itself is already a fire hazard. In the fourth place, the device has many moving, rotating and rubbing mechanical parts, which requires frequent inspection of the device and constant maintenance at altitude, and produces a lot of noise.

In addition, the prior art device for removing ice from the roof, disclosed in US 8689500 B2, publ. 04/08/2014, prototype. The device contains many vibrating elements with an electric motor mounted on the inner surface of the roof, a power source connected to many vibrating elements spaced throughout the roof.

The disadvantage of the device disclosed above is that this device is designed solely to provoke the disappearance of the snow cover and only if the inclination of the roof allows it. When using this device, it is possible that without dropping the ice from the roof canopy the snow cover may not come off, because obstacle to the free flow of snow due to congestion formed in the form of ice on the roof visors.

IMPLEMENTATION OF A USEFUL MODEL device operation

The claimed device for dumping ice and icicles from the roof peaks (1) contains a beam (2) of metal-containing material, one side surface of which is rigidly fixed along the inner surface of the peak (5), low-voltage vibration motors (4) are rigidly fixed through the frame (3) on the beam (2) along it on the upper surface. In this case, the frame (3) is fixed on the beam (2) in such a way that it is shifted by 50% of its size in the opposite direction from the mounting of the beam (2) to the visor (5), and the vibrating motor (4) through the frame (3) is rigidly fixed on the upper surface of the beam (2) so that the central horizontal axis of the specified motor (4) runs parallel to the plane of the second side surface of the beam (2), which is not fixed on the surface of the visor. Beds (3) with vibrating motors (4) are fixed on the beam (2) so that the distance between adjacent beds is 1-1.8 m.

As the metal-containing material of the beam (2), steel, aluminum or another metal or alloy is used having sufficient rigidity to transmit vibration. The beam (2) has a cross-sectional area in the form of a square, rectangle, channel or L-shaped.

The claimed device is mounted on the visor (5) or on the extension of the visor (5), in case of insufficient length of the main visor for the mounting location of the claimed device, as follows. A beam (2) 2.5-3 m long is joined by the ends and rigidly attached around the entire perimeter of the roof (1) to the visor (5) using a threaded connection (bolt-nut). At the same time, vibrational motors (4) are rigidly fixed to the beams (2) through the frames (3) by means of a threaded connection (bolt-nut) at a distance of 1-1.8 m between adjacent frames (3) along the roof perimeter, and the frames ( 3) rigidly fixed by welding. Each vibrating motor (4) at start-up creates a vibrational force of 5-20 Kg and is powered by a power wire (7) (low-voltage regulated power supply of 5-12 Volts). Vibration motors are used that have two flywheels on the axis with an offset center of gravity with respect to the central shaft of the motor, located on both sides of the electric motor, while the flywheels are installed at the same level relative to each other, or vibration motors with directional vibration. In addition, the beam (2) in the places of installed vibrational electric motors (4) is attached to the building or the roof through an unstretched relaxed chain for added security as an insurance in case of fastener breakage and the device falling down. The claimed device is wired by a microcontroller, which is installed in a moisture-proof shield at a height of 3-4 m on the wall of the building and controls the operation of the device manually, or through the application in a smartphone, tablet or laptop via Wi-Fi. The claimed device is powered by an uninterruptible power supply. The claimed device can be mounted on the visor in accordance with the options disclosed in figure 4-6.

The device operates as follows. During the melting of the snow cover on the roof (1), melt water flows to the visor (5) of the roof (1), where it freezes from the difference in temperature between the roof (1) and the visor (5). The roof (1) is heated by the heat of the building, and the visor (5) is cooled by cold air currents, as a result of which ice with icicles forms (6). To reset the ice and icicles (6), the operator manually or through the application in the smartphone sets the settings for the operation of the claimed device: start a specific vibration electric motor (4) or a group of vibration electric motors (4), operation intervals of vibration electric motors (4), for automatic reset of ice and icicles (3) with a certain periodicity. Then, manually or through the tablet, the vibration motors (4) are started for 1-5 seconds, when the flywheels of the vibration motors (4) rotate, the main vibration appears at the mounting point of the motors. In the case of setting the operation of the claimed device to turn on with a certain frequency, the start of the vibration motors (4) is carried out for 1-2 seconds with an interval between starts of 2-4 hours. The main vibration is transmitted from the vibration motors (4) through the bed to the beam (2), which in turn transmits vibration to the visor (5) or the extension of the visor (5). The main vibration destroys the integrity of brittle ice on the roof (1) at the installation site of the vibration motors (4). Due to the claimed installation of vibrational electric motors (4) through the beds (3), namely: the bed is shifted by 50% of its size in the opposite direction from the beam (2) to the visor (5), and the vibrational motor (4) through the bed (3) ) is rigidly fixed on the upper surface of the beam (2) so that the central horizontal axis of the specified motor (4) runs parallel to the plane of the second side surface of the beam (2), a wave-like vibration of the visor (5) occurs, which is transmitted along the edge of the roof (1) along the entire length beams (2) mounted visor (5), whereby the integrity of the brittle breaks and ice is its separation from the edge of the hood and the roof, and as a result of his fall.

Due to the claimed installation of vibrational electric motors (4) through the beds (3), namely: the bed is shifted by 50% of its size in the opposite direction from the beam (2) to the visor (5), and the vibrational motor (4) through the bed (3) ) is rigidly fixed on the upper surface of the beam (2) in such a way that the central horizontal axis of the specified motor (4) runs parallel to the plane of the second side surface of the beam (2), vibration is generated in the visor (5) at the attachment point of the vibration motor (4) and breakwater azane vibration, which propagates along the length of the beam (2), which leads to the discharge of ice and icicles (6) along the entire perimeter of the roof (1), and not only at the installation site of the vibrating electric motor (4), which leads to an increase in the efficiency of discharge of ice and icicles with roof visors.

The distance between adjacent beds less than 1 m is not advisable, due to the fact that this distance is minimal, in which wave-like vibration can propagate along the entire length of the section between adjacent beds, at a distance of more than 1.8 m, wave-like vibration attenuation occurs and between the beds a section of the roof with ice and icicle, due to the lack of exposure to wave-like vibration.

The claimed device has the following advantages and differences from other existing devices:

1. The simplicity of the device (consists of three main elements)

2. Lightweight device (unlike other existing devices)

3. No constant energy costs (no need for constant nutrition)

4. There is no cause of damage and destruction of the roof (unlike other methods)

5. Reliability and durability of the device (no moving mechanical parts)

6. There are no fixed financial costs for replacing worn items

7. There is no danger of fire (low voltage power supply, anti-short circuit protection system)

8. No need for ongoing maintenance (if installed correctly)

9. The whole system can be fully automated (controller control)

10. There is no violation of the aesthetics of the building (the device is hidden under a visor)

11. Universality of the device (the ability to install on any type of visor)

12. Security of reset (the whole process is controlled from a distance)

13. There is no need to perform complex and dangerous work directly on the roof.

14. The speed of the discharge of ice (several minutes to service one building to discharge ice and icicles from all sides of the building)

15. Full control and timing for the planned discharge of ice and icicles

16. In the absence of electricity in the building, it is possible to use backup power (one battery for 12V medium capacity is enough)

17. When dumping ice there is a possibility of provoking the disappearance of snow cover.
