Description

The invention relates to a liquid distributor with a foldable hose and in particular fire hose, and to a method for producing a liquid distributor.

Generically, the invention is in terms of the liquid distributor from a liquid distributor with a hose and in particular fire hose of pressure in the round section, which is distributed over the hose length provided with lateral outlet nozzles, wherein outlet nozzles of a first row to outlet nozzles of a second row have an angular offset of the emission directions.

Fire hoses are mainly used for fire fighting, but also for a variety of other emergency operations in use. In firefighting their job is to transport extinguishing liquid to the desired location, there to direct a targeted extinguishing agent jet directly into the fire or in the direction of the fire. However, there are also situations where water or other extinguishing agent need not be targeted to a fire source, but e.g. preventively spreading over an area. In combating a forest fire e.g. Often the task is to sprinkle soil surfaces with water in order to prevent or at least delay the advance of the fire beyond this area.

From the US 6,174,496 is a liquid distributor for disinfecting cavities of z. B. Air conditioners known. To a container containing the disinfectant solution is coupled via a valve, a long, slender pipe section, the other end is closed. On a partial length of the pipe section is provided with pointing in different directions outlet openings for the disinfectant. Although the pipe section is referred to as flexible, however, a certain stiffness of the pipe section is a prerequisite for proper handling in the sense of the local problem, otherwise an introduction into the cavities z. B. an air conditioner would not be possible.

The object of the invention is to provide a practical solution for situations in which a planar liquid distribution is sought for the purpose of fire fighting. It is also desirable with the invention, a practical To develop a process for producing such a tubular liquid distributor.

For this purpose, a liquid distributor with the features of claim 1 is first proposed.

A thus designed liquid distributor allows a distribution of liquid on both sides and along the fire hose used. Distributed over the hose length, the hose is provided with outlet nozzles. The liquid emerging from these nozzles is distributed on both sides of the hose length. The achievable width of the liquid distribution depends on the arrangement and orientation of the formed on the hose, radial outlet nozzles. Since the hose is a fire hose from unpressurized state of limp behaving fabric material, it can be folded over its length for transport purposes or even wrap.

To achieve a surface distribution of the liquid targeted to both sides of the fire hose used is proposed with a preferred embodiment, that the lateral outlet nozzles are arranged in at least two parallel rows, and that the angular offset of the emission directions of the two outer rows at least 10 ° and at most 90 ° is. Such an angular offset between the two emission directions avoids twisting or twisting of the tube as a result of the recoil force of the exiting liquid. Preferably, the radial outlet nozzles are arranged distributed on two rows, between which the angular offset of the emission directions is between 10 and 60 °.

To avoid too small a distance between the longitudinally successive each outlet nozzles is further proposed that, viewed in the tube longitudinal direction, in each case one outlet nozzle of a row alternates with an outlet nozzle of the other row.

It is further proposed that the outlet nozzles have a guided through the tubing nozzle housing, which is supported under Zwischenklemmung the tubing against the outside as against the inside of the tubing. For a particularly simple and permanent attachment of the outlet nozzles in the hose jacket is also proposed that the nozzle housing are riveted in the tubing.

To avoid an excessive pressure drop in the direction of the free end of the liquid distributor, it is proposed that the end of the fire hose facing away from the pressure source be closed by a pressure-tight cap attached to the coupling in a pressure-tight manner.

It is further proposed that the hose and preferably fire hose is supported on at least one support bracket on the surrounding ground, and that the hose is passed through an opening of the support frame. This embodiment enables a targeted steering of emerging from the outlet nozzles Liquid jet. Thus, for example, a radiation that is symmetrical to the vertical can also be achieved with a substrate sloping down to one side, or a more one-sided radiation, if this is desired for the respective intended use.

Preferably, the support bracket is provided with a leading from the outside to the opening transverse opening, through which the hose is insertable into the support bracket.

With a further embodiment, it is proposed that the support bracket is designed substantially as an interrupted by the transverse opening on a partial circumference ring.

Preferably, the support bracket is composed of a fixed body with the widest possible footprint, and a rotatable therein and the opening for the passage of the hose having ring member together.

A further embodiment is characterized by a locking element for blocking the rotational position of the ring element with respect to the base body. To be able to rotate about the locking element at the same time the hose around its own axis, the locking element is preferably arranged on the ring member and rotatable with this. Further, the locking element may be provided with an actuating handle, wherein the actuating handle may be located outside the circumference of the base body.

Component of the liquid distributor according to the invention is a hose, or a plurality of hoses arranged one behind the other. Fire hoses are particularly suitable for this application, as they can withstand a high fluid pressure as a result of their fabric reinforcement, and they are also made very robust mechanically are. However, the use of the liquid distributor described here is not limited to the field of fire fighting or preventive fire protection, but also covers other uses of such a liquid distributor.

In Fig. 1 such a liquid distributor using a single fire hose 1 is shown. Fire hoses are made of a very pressure-resistant fabric material, which is usually provided on both the inside and on the outside with a rubber coating. The fabric material behaves essentially flaccid in a pressureless state, so that fire hoses can be folded over their length for transport purposes or even be wound. The round cross section in the pressure mode is thus in a depressurized state to a flat cross-section.

At its two ends of the fire hose 1 is provided with couplings 2 and in particular with fast lockable bayonet couplings. These are identical and therefore interchangeable. In particular, the bayonet couplings 2 are designed so that either each end of the fire hose with another, a similar coupling having fire hose is connectable.

According to Fig. 3 the bayonet coupling 2 is provided with bayonet hooks 3, which are locked by partial rotation of the clutch with respect to another clutch. To rotate a rotatably mounted on the bayonet coupling locking and unlocking 4 serves.

At the liquid distributor after Fig. 1 the fire hose 1 is connected at one end to a pump P for generating water pressure. The arranged at the other end of the Feuerwerschlauches 1 bayonet coupling 2 is closed by a pressure-tight patch on the clutch, pressure-tight bayonet cap 5. Water pressure can not escape there. The bayonet cap 5 is in detail and separated from the bayonet coupling 2 in the Fig. 3 shown.

Along the fire hose 1, this is evenly distributed over the hose length, provided with radial outlet nozzles 11, 12. Fig. 1 shows further that the outlet nozzles, viewed in the longitudinal direction, are distributed over two rows of outlet nozzles. The outlet nozzles of the first row are designated by the reference numeral 11, the outlet nozzles of the second row by the reference numeral 12. The arrangement of the outlet nozzles is such that in the tube longitudinal direction in each case an outlet nozzle 11th which alternates one row with an outlet nozzle 12 of the other row. The distance between a nozzle 11 and the next nozzle 12 is preferably 30 to 50 cm.

The rows with the outlet nozzles are not distributed over the entire circumference of the fire hose, but only over a partial circumference, as the sectional view Fig. 4 lets recognize. In this case, the outlet nozzles 11 of one row to the outlet nozzles 12 of the other row on an angular offset w of the emission directions R, which is at least 10 and at most 90 °. Preferably, the angular offset w is between 10 and 60 °.

In the embodiment described here, the outlet nozzles are arranged in two rows. It is also possible to arrange the outlet nozzles in more than two rows, but even then the angular offset w between the outer of these rows is not greater than the values given above.

The advantage achieved with the angular offset w consists in stabilizing the fire hose 1 resting on the floor 13. When the hose is pressurized, for example, on the floor 13, the repulsion forces of the liquid jet emerging from the left outlet nozzles 11 and the right outlet nozzle 12 neutralize so that the fire hose its in Fig. 4 shown position with an injection to both sides obliquely upwards by itself or retains in printing operation. The hose will not tip over.

Experiments have shown that in the arrangement of the outlet nozzles 11, 12 in the in Fig. 4 shown configuration with an angular offset of eg 50 °, a distribution of the liquid over a width of 15 m on both sides of the fire hose 1 is possible. Here, the usual liquid pressures of 15 to 20 bar are used in a fire hose.

The outlet nozzles 11, 12 each have a guided through the tissue of the tubing 14 nozzle housing 15, which is supported with Zwischenklemmung the tubing 14 against the outside as against the inside of the tubing. To facilitate the assembly of the nozzle housing 15, these are riveted from the outside in the tube material 14, wherein the rivet is supported against the tube material 14 from the inside via an annular disc 15a.

In the application of the liquid distributor, it may be desirable that not all of the exit nozzles 11, 12 are simultaneously in operation. For this purpose, each individual outlet nozzle 11, 12 can be optionally closed. For this purpose, a connected to a valve outer ring 16 of the nozzle housing 15 can be locked by turning between an open and a closed position. Alternatively, individual outlet nozzles 11, 12 can be closed by blind plugs 17 (FIG. Fig. 5 ) which are plugged into the nozzle channel 12a.

In the embodiment according to Fig. 2 two fire hoses 1 are coupled together in series, resulting in a liquid distributor with double working length. Both ends are each connected to a pump P. In this way, a ring manifold can be realized with even larger-scale liquid distribution.

In the embodiment of the FIGS. 5 and 6 the fire hose 1 of the liquid distributor is supported via at least one annular support bracket 19 on the floor 13 of the environment. Because in many cases of practice, the in Fig. 4 shown situation in which the hose can be supported on a horizontally flat bottom 13, not given, for example, to a side sloping terrain. Nevertheless, in order to achieve a symmetrical to the vertical radiation or a targeted unilateral radiation of the outlet nozzles 11, 12, the support frame 19 offers the possibility of fixing the rotational position of the tube over a relatively wide angular range.

The in Fig. 5 in a sectional view and in Fig. 6 Support bracket 1 shown in a front view consists primarily of a base body 20 with a wide footprint 23 and a rotatable in the base body and provided with a circular opening 21 ring member 22 through the opening 21 of the ring member 22 of the fire hose 1 is passed. To accomplish this montagetechnisch, the support bracket 19 is provided with a leading from the outside to the opening 21 transverse opening 24. For practical reasons, this transverse opening 24 obliquely above. It is sufficiently wide to pass through the not yet pressurized and thus flat foldable fire hose. Once it has entered the round opening 21, it can expand under pressure in the opening, wherein the outside of the tubing 14 is supported from the inside against the opening 21, so that the fire hose sits substantially free of play in the circular opening 21.

The insertion and removal of the fire hose serving transverse opening 24 passes through, such as Fig. 6 can be seen, both the ring member 22, as well as the likewise predominantly ring-shaped base body 20. If the ring member 22 is rotated in the base body 20, as indicated by the arrow 25, closes the transverse opening 24th

To rotate the ring member 22 and thus the flush from the inside of the ring element adjacent fire hose 1, an actuating handle 30 is provided, which is located outside the circumference of the predominantly annular base body 20. The actuating handle 30 is designed as a toggle and is part of a locking element 31, which engages with a screw thread 32 in a radially arranged threaded bore of the inner ring member 22. Therefore, when the operating handle 30 is rotated around the central axis 33, thereby the ring member 22 is rotated with the fire hose around its own axis. If the operating handle 30 is upwards, as shown in the drawing, the transverse opening 24 is completely open. Furthermore, a locking of the ring element 22 is provided. For this purpose, the actuating handle 30 is supported externally on the base body 20 with the interposition of an annular disc 37. By tightening the knob so the ring member 22 is clamped against the surrounding body 20, and thus fixed in this rotational position. In this respect, the operating handle 30 performs a dual function: it is help in turning the ring member 22, and also takes over the locking or locking of the ring member 22 in the base body 20 in the respective desired rotational position.

In Fig. 7 is a section through one of the outlet nozzles 11, 12 of the liquid distributor shown. The outlet nozzle consists of the nozzle housing 15 forming the nozzle channel 12, which is formed widened in its head region 41, and the already described annular disc 15a and a washer 15b. The generous dimensioning of these two discs avoids excessive buckling of the fire hose in the area of the outlet nozzles. The fixing of the outlet nozzles in the tubing 14 is carried out by riveting by the nozzle housing 15 is compressed in the compression portion 42 by deformation forces. As a result, the annular disk 15a forming the inner part of the outlet nozzle is fixed to the nozzle outer part, and at the same time pressed against the hose material 14 from the inside.

Based on FIGS. 8 to 10 will be shown below, by which method the outlet nozzles 11, 12 are riveted in the tubing.

Fig. 8 shows in plan view a processing table 45 with a movable along the processing table 45 processing and placement device 46. The processing table 45 is very long, since it must accommodate at least the entire length of the deployed fire hose 1. The processing and equipping device 46 is provided with a placement tool 47 located above the fire hose 1. The placement tool 47 is in the embodiment described here, a workpiece holder for a nozzle outer part (ie the nozzle housing 15), within the placement device 46 combined with a riveting apparatus and optionally a punching tool.

The design of the outlet nozzles according to Fig. 7 requires an inner part in the form of the annular disc 15a. This must be mounted from the inside, for which purpose a magazine carriage 48 provided with corresponding workpiece holders is arranged inside the tube. The magazine carriage 48 is in the FIGS. 9 and 10 shown in detail, in Fig. 8 he is covered by the upper layer of the fire hose 1. For transporting the magazine carriage 48 through the fire hose 1 through in the transport direction 49, a pull rope 50 is attached to the front end of the magazine carriage. The traction cable 50 is deflected at the front end of the processing table 45 via a roller, then leads under the processing table 45 to its other end to be connected there via another roller to the other end of the magazine carriage 48 at 50a. The traction cable thus forms an endless tension element, so that the transport of the magazine carriage 48 through the hose is possible both in one direction and also in the other direction and at any desired longitudinal positions. This transport is done either by hand, or by means of an electric drive over which the pull cable 50, 50a is guided. An electronic control unit with position sensor positions the pull rope and thus the magazine slide.

Since the magazine carriage 48 runs poorly on the rough and rubberized inside fire hose hoses inside of the fire hose, a rail 51 is also present, which leads along the entire length of the fire hose through it. For their assembly, the rail 51 is preferably divisible into individual longitudinal segments. The rail 51 is provided with guide structures which cooperate with corresponding guide structures of the magazine carriage 48, thus guiding the magazine carriage 48 as it travels along the interior of the fire hose and allowing it to slide more easily.

The magazine carriage is, like the above FIGS. 9 and 10 show, provided with a plurality of workpiece holders 54. In each of the workpiece holders 54 sits in each case an inner part of the outlet nozzle, so one of the annular discs 15a. The arrangement of the workpiece holders 54 takes place in two parallel rows corresponding to those two rows in which the finished outlet nozzles are arranged on the tube 1. The number of stored in the magazine carriage workpieces 15a is also sufficient to provide as possible the entire fire hose with the intended outlet nozzles.

At its front end of the magazine carriage 48 is provided with a stable surface which serves as a punch abutment 55. A stamping tool can be driven against this stamping abutment 55, which is integrated in the mounting device 46. The procedure is as follows:

The fire hose 1 is laid flat on the elongate processing table 45. The preferably segmented rail 51 is inserted. Then, the magazine carriage 48, which is completely equipped with annular disks 15a, is placed on the rail 51 and drawn into the fire hose 1 by means of the cable 50. First, the magazine carriage 48 is positioned so that an opening is punched into the hose material by means of the punching tool integrated in the mounting device 46. In this case, the stamping abutment 55 of the magazine carriage 48 lies opposite the punching tool. In a next step, the magazine carriage 48 is transported further so far that a workpiece holder 54 with the annular disk 15a stored therein passes under the mounting tool 47. The distance distances required for this purpose can be coordinated by means of a sensor which detects the movement of the traction cable 50 and controls the drive of the traction cable 50 via a control unit.

If the respective workpiece holder 54 is located exactly under the placement tool 47, the nozzle outer part (nozzle housing 15) held in stock in the assembly tool 47 is guided through the tube material 14 as well as through the workpiece holder 54 of the magazine slide. For this purpose, there is a sufficient clearance 56 below the workpiece holder 54 of the magazine carriage 48, cf. Fig. 10 , Then, by means of the riveting apparatus, the riveting of the nozzle parts, wherein the annular disc 15a is taken from its workpiece holder and pressed against the tube material, as in Fig. 7 shown.

Then the next riveting takes place. This concerns the laterally adjacent, on the same longitudinal section of the magazine carriage arranged workpiece holder 54, a repositioning of magazine carriage 48 and assembly tool 47 in the longitudinal direction is not required. The placement tool only has to be repositioned laterally to the other longitudinal axis.

If, however, a workpiece receptacle 54 offset in the longitudinal direction is required for the next joining step, both the magazine carriage 48 and the placement tool 47 must be repositioned in the longitudinal direction. For this purpose, the repositioning of the magazine carriage 48 takes place in comparison to the repositioning of the placement device 46 with a path difference D, or an integer multiple thereof. According to Fig. 9 is the path difference D, the longitudinal distance between the center axes 57 of two consecutively successive workpiece holders 54. However, if the opening must first be punched in the tubing, the magazine carriage 48 is initially in an intermediate step to move so far that initially the punch abutment 55 among the Stanzapparat arrives.
