Description

DESCRIPTION

Cleaning device

TECHNICAL SECTOR

The present invention relates to a device for cleaning large surfaces, for example for ferromagnetic industrial walls such as steel containers. It is applicable in the field of industrial cleaning.

STATE OF THE ART

The cleaning of large surfaces, such as gas tanks, fuel tanks, ship's sides, etc. It takes a long time since it is necessary to have cranes that lift the operators or large robotic arms that must be controlled. For example, the DE2410925A1 machine is known, which includes a truck and a robotic arm with large brushes.

This mechanism is capable of cleaning any type of surface, but it needs a large weight to compensate for the extended robotic arm. Also, this arm has an extension limitation, so it cannot reach any desired point.

The applicant does not know of any solution to these problems as effective as the one claimed.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a cleaning device according to the independent claim.

Its main advantage is that it allows cleaning of any surface, be it vertical, oblique ... from the first point, taking advantage of the lightness of the cleaning arms. Cleaning can be done from a higher point, from a lower point or even to both sides.

The most basic way of realizing the ferromagnetic surface cleaning device of the invention starts from a mobile base and at least one cleaning station with cleaning nozzles. Cleaning stations are mobile inside of at least one slotted tubular arm fixed to the base. This arm may have a pulley system to guide it, especially when tilting. The cleaning stations are arranged at the end of two incompressible pipes that run inside the tubular arm. In this way the cleaning station can be moved by inserting or collecting the pipe. Each arm is finished with a support intended to contact the surface to be cleaned and slide on it. For this it has wheels, tracks or sliding skates (for example, Teflon). Wheels, tracks and the like may or may not be motorized.

In one example, applicable to ferromagnetic surfaces, the support further comprises a detachable magnet at its free end. In a preferred embodiment, the magnets are permanent magnets with 90 ° rotatability.

Intermediate stations can be located at points in the pipeline for cleaning on two levels in parallel.

Groups of parallel arms can emerge from the base, each with its own pipe and cleaning station. Thus, it is possible to expel different fluids (water, steam, water with additives ...) consecutively without having to carry out the journey again.

Other particular solutions are included in the dependent claims and are described in detail below.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached where, by way of illustration and not limitation, the following has been represented.

MODES OF CARRYING OUT THE INVENTION

Next, an embodiment of the invention will be briefly described, as an illustrative and non-limiting example thereof.

The cleaning device shown in the figures starts from a movable base (1) from which arises at least one longitudinally slotted tube-shaped arm (2). At Inside each arm there is a longitudinally mobile cleaning station (3), with a nozzle (31) facing the slot (21) of the arm (2). The base (1) can be mobile by its own motor or be moved by users.

Cleaning fluid is supplied through one or more pipes (4) from one or more tanks (11) in the base (1). The base (1) can also be connected to an external tank (not shown) to avoid transporting large amounts of liquid. The cleaning fluid is pumped from the base (1) or from the external tank so that it reaches all the active cleaning stations (3). The cleaning fluid can be water, water with dissolved products, steam, or a combination of several types, each with its own pipe (4) or its own assembly of arm (2) and pipe (4) (figure 2).

Each arm (2) also includes supports (5) at their free end, to rest on the surface to be cleaned. These supports (5) preferably have wheels (51) or sliding elements to be able to move on the surface, if desired. The displacement will normally be perpendicular to the arm (2). Depending on the type of surface, the supports (5) can have fixers (not noticeable) to the surface. If it is a ferromagnetic surface (steel ...) magnets can be used, while other surfaces may require suction cups. The fasteners are detachable so that they can be separated from the surface to be cleaned. For example, the magnets can be electromagnets or permanent magnets that can rotate 90 ° in situ to stop offering a pole to the magnetic surface. The suction cups can be attached to suction motors that vacuum or not.

The arms (2) can be flexible or articulated, but in any case they are "passive" and cannot move by themselves, but it is the base (1) that drags them. In this way, the arms are light and can have a long length The supports (5) allow the weight of the base (1) to be removed, which does not need to be so heavy to prevent overturning.

The arms (2) can be arranged upwards from the base (1), downwards, horizontally to one side or the other, or in any direction. For this, it is preferred that they be attached to the base (1) by means of a joint. In this way the device can travel a passable path and the arms (2), which are light and self-supporting, perform cleaning of the surfaces.

The arms (2) can be modular, so that a variable number of modules can be placed to lengthen or shorten their length. It is preferred that the final module It includes a stop, which can be the support (5) so that the cleaning station (3) does not slip out of its way.

A control unit (not shown), which can be remote, allows the device to be commanded, ordering the base (1) to advance or reverse, the cleaning stations (3) to move and separate from the base (1) or running across the surface. It is also possible to program an alternative movement of the base (1) and the cleaning stations (3) to cover the entire surface to be cleaned. First the base (1) advances a first distance equivalent to the zone of influence of the cleaning stations (3) and then they travel their respective arm (2) to clean the surface.
