RU42559U1 - DEVICE FOR PREVENTING ICE DRAINAGE OF WATERPROOF BUILDING SYSTEMS - Google Patents

Abstract

The proposal relates to the maintenance technology of drainage systems of buildings by special equipment of drainpipes and to prevent ice plugs from freezing in them, disrupting their operation and leading to an emergency condition of these systems. To perform this technical task, the device includes a drainage funnel 2 adjacent to the guide spillway 1, connected to the elbow 3 of the drain pipe 4. At the junction of the elbow 3 and the pipe 4, the diameter and cross section 5 (with non-radial section) are chosen to be smaller than the diameter and cross section of pipe 4, moreover, the connection is made misaligned, but with a displacement of the axes, which prevents the water from flowing out along the wall of the pipe 4, which has a lower temperature and prevents the formation of ice on the wall of the pipe 4. To orient the flowing water to the cut the inner tube is made one - 6 or 7 neskolko- oblique sections in the course of the swelling water, allowing the water guide pipe is not on the walls 4 and to prevent ice formation in them. Also, to orient the water flowing out, the bell 2 can be connected to the pipe 3 misalignedly and eccentrically, which makes it possible to organize hydrocyclonic flows that do not completely clog the cross-section of pipe 3 during intensive spillage from the protected roofs of buildings and structures.

Description

The proposal relates to technology and technical means for a gutter from roofs and roofs of buildings and structures, and relates, in particular, to the design of drainpipes equipped with special elements to prevent accidental operation.

At present, fundamental technical solutions are known in this area of servicing the gutters of buildings and structures, of which the most representative is a device containing flat heat transfer linings connected to a power supply network and designed to heat ice formation places on the roof of a serviced building / RU No. 2169245, E 04 D 13/00, 06/20/2001 ./.

A significant and obvious drawback of such a device is the need to supply electricity to the heat transfer elements, which is associated with the condition that high safety standards are observed due to the humidity of the device’s environment, which sharply limits the possible areas and list of objects for its use.

The closest in technical essence and the achieved result is a device to prevent icing of the drainage systems of buildings, containing a mechanical vibrator of spring elements placed on the eaves and in the intake funnels of the sewer placed in special buildings / RU No. 1548384, 10/11/1986 /. Or a device containing an electric heating element in the cavity of a drainpipe / RU No. 1723287. E 04 D 13/06, 11.06.I986./.

A significant drawback of such a device is the presence of spring elements that are vulnerable to operation during icing, requiring external influence on them, which, for example, at night is not always possible; and in the case of operation of the device on an electric heating element, it becomes necessary to monitor the serviceability of the switches supplying the current system. which is associated with additional

labor and energy costs for the process of preventing ice formation in the drainage systems of buildings.

The technical task and the result of this proposal is to increase the reliability of the process of preventing icing of drainage systems while simplifying the design and operation of drainage systems of buildings and structures.

This is achieved by the implementation of the device to prevent icing and ice formation of the drainage systems of buildings and structures in the form of a drainpipe with a drainage funnel adjacent to the drainage channel, in the form of interconnected parts, where each subsequent part of the pipe, starting from above, has in its cavity a directing funnel, the outlet cross-section of the funnel is made smaller than the cross-section of the drainpipe and provides a free fall of water along the cavity of the drainpipe.

Moreover, the connection of the drainpipe parts is made without observing their alignment, and it is also possible that the opening of the drainage funnel is eccentric to its diametrical section.

It is preferable to cover the walls of the drainpipe, drainage funnel and spillway funnel with a hydrophobic material.

The described device is illustrated in the accompanying drawings, where;

figure 1 shows a General view of the device;

figure 3 - connection of the drainage funnel with the pipe;

figure 4 and figure 5 - the implementation of the pipe;

Fig.6 and Fig.7 - the implementation of the inner funnel of the pipe.

A device for preventing icing of drainage systems comprises a drainage channel 1, a drainage funnel 2 and a drainpipe with its elbow part 3 and a vertical part 4, fixed to the wall of the building. The implementation of the pipe is original due to the inclusion of water-guiding units in its design, which ensure free water fall without swelling it along the walls of the pipe 4, which prevents freezing of water on its walls when snow melts during weather and daytime thaws. In this case, the pipe is made of sections (segments), each upper section or has

the input diameter of the pipe 5 is less than the diameter of the pipe section 4 (FIGS. 1, 2), which ensures that the water does not flow onto the pipe wall 4, but its free fall along its cavity, while the section of the pipe section 5 can be made with bevel 6 or several bevels 7 (FIGS. 4, 5), which further ensures water to flow into the free cavity of the pipe 4. without wetting its wall, preventing freezing of water on the pipe walls.

To increase the guarantee of water ejection, especially during periods of daytime temperature increase and thawing of snow on the roofs, the drainpipe is equipped with a guiding spout funnel 8 (Fig.6), the outlet section 9 of which strictly orients the water ejection along the middle section of the free cavity of the pipe 4, avoiding freezing water on the walls of the drainpipe and thereby preventing the formation of ice plugs in the cavity of the pipe.

With a significant length (height) of the drainpipe serving the drain of a high-rise building, it is advisable to make several such guide spillway funnels 8 along the height of the pipe 4, so that along its entire height to ensure the direction of water flow in the middle section, preventing uncontrolled dropping of drops and preventing freezing of water on the walls pipes 4. In this case, it is possible to make bevels 10 of the outlet openings of the guides of the spillway funnels 8 (Fig.6, 7). The initial function of the direction of the flow of water can also be carried out by an misaligned connection of the pipe section 3 and the drainage funnel 2 (Fig. 3), which ensures cyclical swirling of the flowing water along the tray 1 of the drainage system ”A at significant differences in air temperature / Winter in St. Petersburg, the differences between daytime and nighttime temperatures reach 10 ... 15 ° С and more /, when the temperature of the external walls of the building affects the drainpipe, exposing it to temperature effects, the connection of pipe sections 5 and 4 can be eccentric o (Figure 2, section A-A).

Thus, the developed device provides a controlled process of the drainage systems of buildings and structures, preventing freezing of water on the walls of the pipes and increases the reliability of their work.
