- FIG. 1 shows, in elevation, a device according to the invention
- FIGS. 2, 3 and 4 show three successive phases of the use of the device for cleaning a tube
- FIG. 5 is a diagram illustrating possible control means of the device according to the invention.
- FIG. 6 is an axial section of the device in operation inserted in a tube
- FIG. 7 is a section similar to Figure 6 in another operating situation
- FIG. 8 is a partial section of the device showing a detail of its design
- FIG. 9 is a " diagram illustrating an alternative embodiment.
- the device of FIG. 1 comprises two similar brushing assemblies, respectively designated by the references 10 and 20. They each comprise brushing means, respectively 12 and 22, as well as "a propellant element 14 and 24 respectively.
- the device is intended to clean the internal periphery of a tube.
- the axial direction D will be that of the geometric axis of this tube, that is to say that in which the device of the invention moves inside the tube.
- the brushing means therefore extend transversely to this axial direction D, and the bristles of the brushes are directed radially so as to be able to rub the internal periphery of the
- the propellants 14 and 24 are also arranged transversely to the direction D.
- the brushing means 12 or 22 each comprise several series of brushing discs. arranged one after the other and having different brushing effects.
- a first brush 12A Nylon ® a second and a third brush 12B and 12C of brass, and a fourth brush 12D bronze.
- the device of the invention is intended for cleaning tubes of circular or substantially circular section.
- the tubes can also have a very slight taper.
- the diametrical dimensions D1 of the brushing means must be slightly greater than the inside diameter of the tube that the device is intended to clean.
- the brushes of the brushing means 12 and 22 are bent towards the inlet 1A of the tube, that is to say towards the 'rear relative to their direction F of introduction into the tube.
- the propellants 14 and 24 also have diametrical dimensions D2 greater than the internal diametrical dimensions D ⁇ of the tube 1. They are at least equal to or slightly greater than the diametrical dimensions D1. It can also be seen in FIG. 2 that, when the device is inserted into the tube, the propellants 14 and 24 are arched so as to have a concavity facing the inlet 1A of the tube.
- the brushing assemblies 10 and 20 are mounted so that they can be moved axially with respect to each other alternately in the direction of approaching and moving away. Thus, from the situation in FIG. 2, it is possible to discard the assemblies 10 and 20 as shown in FIG. 3. These assemblies 10 and 20 are similar, that is to say that they are chosen so as to exert substantially the same reaction forces against the inner periphery of the tube 1 when they are introduced into the latter. Furthermore, the resistance that the brushing assemblies oppose to their advancement in the direction F inside the tube is less than the resistance that they oppose to their retreat in the direction G. This is due to the direction of their concavity. Due to the orientation of the edges of the propellants, the friction forces opposing a recoil are higher than those opposing a advancement. A retreat would seek to reverse the concavity while the sense of concavity is of course preserved during advancement.
- the propellants 14 and 24 have been functionally distinguished from the brushing means 12 and 22.
- the propellants can be relatively rigid brushes. It has in fact been observed that the brushes having extremely fine bristles or a low rigidity tend to twist inside the tube after a first phase of advancement, by placing themselves substantially in a radial plane, in which case the concavity previously evoked tends to disappear. It is then no longer possible to advance the two brushing assemblies in the tube in the manner indicated above.
- a sufficiently rigid brushing element for example a brush whose bristles are sufficiently thick and dense to retain the axial bending which was imposed on them when they were introduced into the tube.
- the propellant element 14 or 24 may be a brush, similar to one of the brushes 12A to 12D previously mentioned and the stiffness of which will be suitably determined.
- the choice of making the propellant element in the form of a brush has the advantage of making the latter participate in the cleaning of the tube or, at least, of preventing the contact of the external periphery of the propellant with the inner periphery of the tube does not cause clogging of the streaks of the latter.
- propellants 14 and 24 are disc-shaped plates, made of synthetic material such as elastomer, this material being chosen so as to have a relative rigidity or an elasticity so that, once the propellant has been introduced into a tube and has a concavity turned towards the inlet of the latter, the concavity of this propellant element will be difficult to reverse inside the tube.
- the brushing assemblies 10 and 20 are mounted on a support system such that the brushing means of one brushing assembly can rotate freely with respect to the brushing means of the other brushing assembly.
- the brushes are mounted on crowns whose internal periphery is cylindrical.
- the support elements 30, 40 or 35, 45 have cylindrical external surfaces on which these rings are arranged.
- the two brushing assemblies 10 and 20 are similar and in any case have substantially the same resistance to advancement inside the tube.
- the brushing means 22 relatively soft "soft" brushes, while harder brushes would be chosen for the brushing means 12.
- the propellants 14 and 24 would be chosen from so as to present a resistance to advancement such that the difference in resistance to advancement between the brushing means 12 and 22 is compensated if it is not negligible.
- the brushing assemblies 10 and 20 are respectively mounted on a first and on a second support element, 30 and 40. These two support elements can slide relative to each other so as to be alternately brought towards and away from each other. the other.

- the device can be engaged in the tube being manipulated by a handle 33 located at the end of the brushing assembly 10 opposite the brushing assembly 20. Once the device engaged in the tube, one can perform a brushing step and progression of the brushing assemblies towards the second end 1 B of the tube in the manner indicated above.
- the first brushing assembly (in this case the assembly 20) reaches the second end 1 B of the tube.
- the tube can then be brushed again by advancing the device in the opposite direction.

- a brushing and progression step of the brushing assemblies is then carried out towards the first end of the tube, alternately moving the brushing assemblies apart and bringing them closer to one another.
- the end part 42 is accessible and, sometimes, the brushing assembly 20 emerges from the tube or is in a chamber . larger diameter. Even if the movements of distance and approximation are continued, the brushing assembly 10 no longer progresses towards the exit because the brushing assembly 20 no longer bears on the internal periphery of the tube. To extract the device from tube, it is therefore necessary to pull the gripping end 42, for example using a cord.

- the seals 68 are not in tight contact with the bore 63, so that the friction of the drawer 67 in the bore 63 is very low and the displacement in the direction F1 initiated by the abutment continues with a dynamic effect until the slide 67 reaches its stable position in FIG. 6.
- the device is equipped with a projection system 72, 74, 78, 80, 82, 84, 85, 86 of a fluid 76 (detergent, lubricant, etc.) shown. in FIGS. 6 and 7.
- This projection system 72, 74, 78, 80, 82, 84, 85, 86 formed in the front part of the device beyond the first, brushing assembly 20, comprises a reservoir 72 located in the support element 40.
- the reservoir 72 is connected to a filling orifice 74 opening at the periphery at the free cylindrical end 75 of the support element 40 which makes it possible to fill the reservoir 72 with fluid 76 (lubricant, cleaner, etc.) using a metering device, for example, containing the quantity sufficient to carry out cleaning of the tube 1.
- This quantity is preferably determined to carry out a flow in the tube 1 and that the reservoir 72 is completely empty at the end of the passage to avoid inadvertent projections of the fluid 76.
- the reservoir 72 being driven in rotation when the support element 40 rotates in the propeller formed in the tube for example, it is necessary to be able to close the filling orifice 74 with a plug 78.
- the latter is connected to the periphery 75 of the brushing element 20 by projection means.
- These means comprise a pipe which connects inside the reservoir 72 to at least one fluid outlet 80 and nozzles 82.

- the end 84 'of the pipe 84 which dips in the fluid 76 remains substantially stationary in rotation, despite the rotation of the reservoir 72.
- this end 84' is made heavier by a counterweight 85.
- the flexibility of the pipe 84 used, combined with the presence of the flyweight 85, allows the pipe 84 to remain in the bottom of the reservoir 72 during the rotation of the latter with the brushing assembly 20. In the case where the device does not rotate, this flyweight 85 has the interest in maintaining the 84 'inlet end of the pipe 84 in the bottom of the reservoir 72, whatever the initial angular position of the device during the introduction of the brushing assemblies 10, 20 into the tube 1.
- the device is inserted into the tube to be cleaned preferably - slightly inclined (for example by an angle equal to 4 °) relative to the horizontal, in order to allow its access at breast height to carry out its cleaning.
- the inlet 1A is lower than the outlet 1B of the tube 1 and the reservoir 72 is also slightly inclined, which causes the inclination of the fluid 76. Therefore, even at the end of use, when it remains very little fluid 76, the pipe 84 remains in contact with the latter.
- the reservoir 72 is partially filled with the fluid 76 maintained under pressure by taking compressed air from the chamber 58.
- a valve 88 calibrated using a spring 90, is disposed between the chamber 58 and the reservoir 72. If the cylinder operates at a pressure of 5 bars, it is possible, for example, to preset the opening of the valve to 4 bars. Consequently, the pipe is constantly supplied with the fluid 76, so that the fluid 76 is sprayed alternately by the nozzles 82 on the internal wall of the tube 1 by jets which follow the rotation of the brushing assembly 20. Half of the time of use, the chamber 58 is not supplied with pressure, but is in the exhaust phase.
- the pressure in the reservoir 72 remains sufficient to cause the pulsed projection of the fluid 76 during this 1 phase, until the chamber 58 is again under pressure.
- the nozzles 82 are driven in rotation by specific means (not shown) free to rotate in rotation relative to the support element 40 containing the reservoir 72 under the effect of the pressure of the fluid 76.
- a rotary seal will preferably be arranged between these specific means and the support element 40 in the vicinity of the reservoir 72.
- the preferred operating method consists in carrying out a first outward pass of the brushing assemblies 10 and 20 with projection of the fluid 76, for example a detergent fluid, which will make it possible to take off well all the dirt adhering against the internal wall of the tube 1.
- the return preferably done dry.
- a second round trip of the brushing assemblies 10 and 20 is carried out dry.
- Each of the brushing assemblies 10 and 20 is then covered with an absorbent material (not shown), in the form of tissue or paper for example, held on the device and there is a return trip of the device to remove all of the sprayed fluid 76 , as well as dirt that would still be present.
- the brushing assemblies 10 and 20 can be completely replaced by this absorbent material.
- FIG. 9 shows a variant for mounting and moving the two brushing assemblies 10 and 20 relative to each other. They are mounted on two support plates, respectively 35 and 45.
- the displacement control means comprise a motor 60, for example an electric motor, and means for transmitting the movement. These means comprise for example a connecting rod 62 which is driven by the motor to transmit an alternating linear movement to a cable 64.
- This cable is disposed in a sheath 66 at the end of which the plate 35 is mounted.
- This sheath 66 is flexible while being rigid enough not to have a tendency to deform axially by compacting on itself.
