FR3087456A1 - RFE - RECOVERY OF WATER LEAKS - Google Patents

Description

The present invention called RFE relates to a device for recovering water in the event of leaks on the cold or hot water inlet columns. It is developed in two designs: a basic one without electrical device and an electrical one with audible and visual alarm device. This invention has the ability and particularity to stop water leaks that could seep into the walls and floors of a building.

Most often we notice that there is a leak when we notice humidity points or worse floods. This infiltration process is insidious. In fact, the leak started a long time ago.

The RFE device, whatever the model used, basic or equipped with the electrical device for detecting water leaks, is intended to eliminate losses such as damage to the walls and ceilings of apartments, walls and ceilings of landings, caused by damage. water during leaks on the water intake columns of buildings for private use or receiving public.

This efficient system simplifies life and saves the hassle caused by water leaks. Its benefit is undeniable and appreciated by everyone: residents, lessors, and others such as insurance companies.

Best of all, it makes it easier for the plumber to repair or replace parts or accessories. Whatever the reason: incident or repair intervention such as replacement of a shut-off valve, a meter, connection joints, the water from the leak or the residual water flows into the recuperator, leaving the ground clean and dry.

The device according to this invention overcomes this problem. With a hose clamp type clamp, the RFE should be fixed just below the meters and stop valves of a water supply column in the landing duct or apartment, itself being connected to a column wastewater in order to evacuate the water thus collected.

According to the embodiments, the RFE device designed in PVC can be flat or triangular. So in this invention, there is a triangular model following the installation of water columns in the landing ducts. Likewise, the device can be adapted to columns of cold or hot water of diameter 60 or 40 by means of an adapter ring.

The discharge of the RFE is connected to a column of waste water or rain water or to any system provided for this purpose.

The standard dimensions of the RFE are 30 cm wide and 25 cm deep and 10 cm high to be installed in standard ducts.

Depending on the model chosen:

- the basic device is sufficient in itself if a physical check is carried out at a frequency to be defined. When the leak occurs in the form of a drip, the water is evacuated and leaves a trace, a deposit visible to the naked eye on the absorption grid. If the flow is continuous even low, the water will flow through the pipe. In both cases, there will be no water damage to deplore and to declare.

- the electrical device equipped with an audible and visual alarm allows you to be warned of the problem in real time.

The accompanying drawings illustrate the invention:

Figure 1 shows a side view of the installation of the basic RFE model.

Figure 2 shows a top view of the RFE equipped with the audio and visual electrical alarm device.

Figure 3 shows section A of the RFE in fig. 2

Figure 4 shows the RFE in rear plunging view

Figure 5 shows the adapter ring made of double-walled PVC.

Figure 6 shows the type of metal hose clamp used for fixing the RFE on the water column.

FIG. 7 describes the electrical diagram of audible and visual alarm.

With reference to these drawings:

[Fig. 1] The RFE device (1) is fixed to the water inlet column (12) using a metal hose clamp (9). A siphon (5) is recommended to avoid the rise of odors.

The electrical audible and visual alarm system is coupled to the connection plugs (7) located on the underside of the RFE (1) at the height of the flow.

The RFE collects water which comes either from leaks at a meter connection (10) or at a stop valve (11). The RFE (1) is very useful when replacing a defective part since the residual water flows into the RFE (1) instead of falling to the ground.

[Fig.2] and [Fig.3]: The mesh size of the absorption grid (2) made of PVC is 2 mm ² and 4 mm thick to keep it rigid. It avoids splashing, obstruction of the flow by the accidental fall of objects, tools, even the intrusion of an animal. It is placed on an inner rim (5) 3 cm below the upper edge of the RFE after the RFE (1) has been fixed to the water column using the flex clamp slipped into the orifice ( 6). Finally, the 30 mm diameter drain (3) is connected to a waste water column or a column provided for this purpose.

The two metal moisture detection grids (4) are kept at a distance of 3 mm using an insulator. They have a diameter of 50 mm. The electrical connection plug side rests on an overhang (8). The opposite edge has a cannula. By applying downward pressure from the RFE, the bead becomes lodged in the cannula. The two metal moisture detection grids are thus clipped to the RFE thanks to the self-locking bead. The passage of a single drop of Water allows the contact which will trigger the audible and visual alarm system. The two connection plugs (7) are slid outwards through a hole at the same level. Their good maintenance is ensured by a rubber seal. These humidity detection grids must be disconnected before each intervention. They must be cleaned and dried before being put back into service, which is why they are removable.

[Fig.4 - 5 - 6] The adapter ring (13) is used when it is necessary to install the RFE system (1) on a column with a diameter smaller than that used in the design of the device. In this case the adapter ring (13) is fixed to the RFE (1) using two lugs (14) to be inserted into the notches (15) provided at the rear of the RFE (1).

The dimensions used for the hose clamp (9) are 30 cm long and 2 cm wide. This collar goes through the holes (6) of the RFE in order to fix it to the Water column.

[Fig. 7] The electrical system, positioned at a distance from the RFE in a private dwelling, installed outside the landing sheaths containing the water columns in collective buildings, is supplied with 220 V rectified (16) with 12 V. It has a backup battery (17) to compensate for any cuts in the electricity distribution. It has the particularity of having a power-on indicator (18) and of being equipped with a protective fuse (19).

As soon as the sensor (20) detects a leak, the device triggers the relay (21) which triggers the continuous buzzer (22). After the time delay, the intermittent beep (23) and the emergency mode LED (24) come on.

The RFE device according to the invention is intended to equip private constructions, old collective buildings (for residential or professional use) but also new constructions whatever their use since it is an independent device.
