RU191422U1 - Anti-icing drain funnel - Google Patents

Abstract

Usage: The anti-icing drain funnel is designed to prevent icing of the drainage system in the winter, consists of a body made of metal or polymer material made in the form of a cylinder 1 and a truncated cone 2, a special drip 3, to which a heating cable 4, located inside the funnel body, is connected. The ends of the heating cable 4 are brought out through a special hole in the cylinder 1 to reduce the required length of the heating elements and integrate the funnel into the gutter anti-icing system. Technical result: increased safety of the drainage system operation, reduced operating costs for heating the gutter system by using a drip reducing the required length heating cable for anti-icing gutter.

Description

The utility model relates to the field of construction, in particular to engineering equipment, namely, to elements of the anti-icing system of external gutters of pitched and flat roofs.

Currently, heating elements of various types and capacities are widely used, placed both inside the drainpipe and drains, and outside (patent for invention No. 2381339). However, the need to lay heating elements along the entire length of the drainpipe leads to large operational costs for the operation of the heating system.

A device for preventing icing of the drainage systems of buildings is known (utility model patent No. 42559). Significant disadvantages of this device are the narrowing of the drainage funnel, which leads to the formation of ice along the edge of the funnel and freezing of the drainage channel in the winter, the relative complexity and multi-link structure, high costs for manufacturing and installation. In addition, the design of the device does not allow its use in existing drainage systems and requires their complete replacement.

The objective of the utility model is to increase the efficiency of protection of the drainage system from icing in winter.

The technical result is to increase the reliability of the process of preventing icing of drainage systems while simplifying the design and operation of the drainage systems of buildings and structures through the use of an anti-icing drain funnel.

This problem is achieved in that the anti-icing drain funnel, consisting of a body in the form of a cylinder and a truncated cone, while the section of the truncated cone is made smaller than the section of the drainpipe and provides a free fall of water along the cavity of the drainpipe, characterized in that the truncated cone has a drip located at an acute angle α not exceeding 45 ° to the axis of the funnel, as well as a heating cable connected to the truncated cone and drip.

The funnels are mounted at the junction of the drainpipes at intervals depending on the configuration of the drainage system. The greatest effect of anti-icing of the gutter system is achieved with the use of heating cables in the gutters, as well as other non-vertical sections of the gutter system.

As a result of using the anti-icing drain funnel, the efficiency of protecting the drainage system from icing will increase. The required heating area will also be significantly reduced when using heating cables to combat the icing of the drain. Reducing the required length of the heating elements will lead to lower operating costs for combating the icing of drainage systems using heating elements. The design of the funnel allows it to be used for all types of drainpipes and integrate into operating drainage systems without replacing old drainpipes, elbows of drainpipes and gutters. In addition, the design of the funnel allows the replacement of individual funnels when they break and heating elements when they are worn and obsolete. A dropper prevents water from swelling along the wall of the drainpipe

The essence of the construction is illustrated by drawings. In FIG. 1 shows a design form of a utility model. In FIG. Figure 2 shows the possible location of installed de-icing gutters in the gutter system.

The anti-icing drain funnel consists of a body in the form of a cylinder 1 and a truncated cone 2 made of metal or polymer material; at the end of the truncated cone 2 there is a drip 3, to which a heating cable 4 is connected. The drip 3 is made at an angle α not exceeding 45 degrees to the axis of the funnel to reduce the area of droplet formation and, as a result, reduce the expansion of droplets during their fall inside the drainpipe . The ends of the heating cable 4 are brought out through a special hole in the cylinder 1 (Fig. 1) to reduce the required length of the heating elements and integrate the funnel into the drain anti-icing system. If the anti-icing drain funnel is located near the gutters and the drain funnel, it is advisable to lead the cable through the inlet of the drain system (figure 2).

The principle of operation of the anti-icing drain funnel is as follows. By lowering the temperature and humidity to the temperature at which ice formation occurs, the heating cable 4 begins to feed, heating of which prevents icing of the truncated cone 2 and drip 3. When melt water enters the anti-icing drain funnel, it does not freeze due to heating of the housing. A liquid accumulates on drip 3 and falls onto an anti-icing drain funnel located below (Fig. 2) or liquid is removed from the drain system through the drain elbow.
