Description

Pneumatic action retention device for water projection.

The present invention aims to create a special aquatic effect similar to an "explosion" of water or a high pressure water projection.

This innovation belongs to the field of special aquatic effects and by extension to the world of multimedia shows The aesthetic effect achieved is similar to that of a "pyrotechnics" of water. When there is a varied number of these devices, water projections can be achieved high-rise, like "hydrotechnical" games, which with the thunderous sound that they produce in their appearance and their performance instant, they produce the impression of contemplating a Water "pyrotechnic games" castle.

Background of the invention

The use of special aquatic effects for the creation of shows it is relatively old, although its industrial use is recent and associated with the shows multimedia and specifically to water shows from sources Interactive and musical. Its use has been extended in the parks themes in which around a lake a show as a surprising means of captivating the attention of visitor.

The aesthetic effect achieved with this invention is that of a water explosion or a water projection to pressure, depending on the pneumatic pressure applied and the nozzle used. A similar aesthetic effect can be observed in other devices currently in existence. An example of a antecedent is the American patent 4852801 of Mark W. Fuller, in the  that in a tube full of water, through pneumatic action, It produces a water projection. The drive system used It is similar but as will be seen in the description of this innovation, the device brings important advantages to the state of the technique regarding the patent cited as background, such as: the incorporation of the retention system in the own drive system (two patents are required in the preceding patent elements: an air intake and a check valve; he system used in the present invention simplifies and maximizes the efficiency of the drive and retention system), the provision of the water pipe horizontally (this is a very advantage important because it allows its use in shallow ponds, such as those used in public sources. The present device accumulates the flow of water along the pond, to Unlike the previous patent, which maintains a provision in vertical that forces the pond to have enough depth to accumulate an equivalent water flow inside), the drive of the "bubble" of air through the base (you get a greater efficiency in water displacement) and the existence of a special nozzle (which allows the appearance of effects different aquatic depending on the nozzle model used).

There are other water projection systems that they use pneumatic action but the example cited as background perhaps it is the one that enjoys a more widespread and popular use in Different variants

Description of the invention

The present invention aims to create an instant action aquatic effect that projects water to high pressure producing a boom in its appearance.

Device description

The following describes in detail the pneumatic action retention device for projection of water that each pipe filled with water needs for its functioning.

The devices that the present invention needs to function they are described in a general way in figure 1. The Pipe (17) at the initial moment is full of water. When the pneumatic valve (3) is activated, the compressed air in the tank (1) flows through the elastic hose (4) through the pipe (17) projecting a pressurized water spout outside the pond. The height reached by the dispenser depends on the air pressure that is regulated instantly through the electronic pressure switch (2). The appearance of the dispenser will depend on the nozzle (5) used. This aspect can vary from a water explosion, if they use emulsion nozzles, a high-rise spout if the nozzle has a design for fluid lamination, effects "lash of water" if the nozzle allows a pendular movement, etc. The final aesthetic appearance can be as diverse as they allow the different nozzles used. For the drive, retention and fast water recharge in the pipe (17) the pneumatic action retention device for projection of water described below.

Function Description

Figures 2, 3, 4 and 5 describe the operation of the device in its four stages of drive

Stage one

Drive. (Figure 2)

The pneumatic electro valve (3) is activated. He Pressurized air flows through the flexible pneumatic hose (4) to through the injector (12) producing a jet of pressurized air that displaces the existing water in the pipe (17), passing through the nozzle (5), outwards.

Stage 2

Retention. (Figure 3)

The pressurized air flowing through the injector (12) produces a reaction movement that displaces the same injector (12) in the opposite direction to the water projection. Attached to the injector there is a plug (9) that when reaching the stop (7) prevents water from leaking from the bottom of the device and thus all the Water is projected outside through the nozzle (5). The dock  (10) is compressed forced by the retainer (20) that is integral with fixed to the injector. The spring (10) functions as a shock absorber and absorbs much of the impact produced by the abrupt movement of the injector and its solidarity parts. Besides of reaction movement produced by the flow of air by the injector, the pressure generated inside the pipe (17) will cause some of the displaced water to project in the direction opposite, thus pushing the plug (9) that will move in solidarity with the injector (12) until reaching the stop (7) and produce thus closing the mechanism tightly and preventing water leakage by that point. The flexible pneumatic hose (4) that is attached to the injector (12) by the piece (8) is compressed to allow the displacement.

Stage 3

Water filling. (Figure 4)

When the air pressure ceases, the injector (12) tends to recover its initial position driven by the spring shock absorber (10) that held by the retainer (20), jointly and severally fixed to the injector (12), it returns to its resting position. To the return the injector (12) to its initial position, the cap (9) is moves in solidarity and allows the entry of water (24) through the base (7) into the pipe (17). Recovery of the flexible pneumatic hose (4) to its resting state accelerates the displacement of the injector (12) to its initial position.

Stage 4

Repose. (Figure 5)

The pipe (17) is again filled with water (24) and ready to drive a new load of water abroad.

The pneumatic electro valve control is will be done through a computer and electronic system. When a number of projection devices are present, this system of control will allow its simultaneous, sequential appearance, one by one, by groups, etc., so that it is capable of generating a show of Attractive, surprising and spectacular water games.

Brief description of the drawings

To facilitate the understanding of what is described in the previous sections, 6 drawings have been made different.

An application is represented in Figure 1 generic that will be described in the section of an embodiment favorite. Figures 2, 3, 4 and 5 show the different acting stages Figure 6 represents a front view and rear of the device, in which it can be seen that centers (21) and (22) allow water to flow through you, being mostly hollow.

Description of a favorite embodiment

An application is described below practice of a pneumatic action retention device for water projection installed in an ornamental fountain pond conventional depth

The arrangement of the set as shown in the Figure 1 develops primarily horizontally. From so that the pipe (17) is much longer than high. This provision allows the use of this water projection system in shallow ponds, which is a novelty to Stand out in this field. Both the retention device and the pipe (17) are firmly anchored to the ground, by means of anchors (14) and (19) integral to the device and the pipe (17), to absorb the sudden blows and pressure changes that They produce inside. The method of joining between the device and the pipe (17) is made by flanges (15) firmly joined by 4 screws with pressure nuts (16), which facilitates enormously the tasks of assembly and maintenance of the equipment and It is a fast and safe method of assembly.

As explained in the description of the device operation, by successive opening and Pneumatic electro valve closure (3) and water recharge of the pipe (17) through the retention device, the spectators can enjoy a show of projections of high water. The height of the water effects is proportional to the air pressure driven by the injector (12) and is regulated by an electronic pressure switch (2) capable of varying Quickly output pressure through control system installation computer. When several sets are available water projection, through the computer control system you can indicate to each of them the projection height desired, so that the show created is very varied, for example a possible application would be for water dispensers could evolve to the sound of music appearing according to the rhythm and varying its height in the air according to the volume of the music. The water projections can be illuminated by projectors multicolored, thus increasing the spectacular effects aquatic
