Description

Cleaning device for sewage basins

The invention relates to a cleaning device for sewage basins, rain basins, aeration basins, sand trap basins and the like with a bridge that can be moved over the basin to be cleaned, to which a water or air supply line leads, which is connected to a water or
Air connection is connected, with the bridge in
pipes protruding from the inside of the basin with spray

or blow nozzles attached to the water or Air supply line are connected «

Sewage basins, rain basins and the like are generally provided with clearing devices through which deposited impurities are cleared. To this dirt-I " · It is known to facilitate sludge removal I these clearing facilities with water supply lines and

· «It

In runoen basins where the supply lines Via a central base, which forms the pivot point for the scraper bridge, to the cleaning device are fed, there are no feed problems.

However, there are problems with the prior art Dei rectangular basins. · The bridge becomes longitudinal Move over the basin. For this reason, the facilities required for cleaning, such as air and water supply devices, blowers and dql. carried on the bridge graze. The water is supplied in the device described in DT-OS 27 01 190 either via a hose reel that can be rolled out, which is located on the scraper bridge, or the water supply lines are connected to a pump that sucks water from a pool of water along the edge of the pool is arranged. The arrangement with the hose on the bridge has the disadvantage that the drainage if there is a risk of frost is not unproblematic and a drive motor is provided for the hose rewind a corresponding iden power supply must be arranged on the bridge. The water supply via the Pump and the water basin or one along the basin

running channel is cumbersome and expensive. The same applies to a water supply via an am Pool edge movable carriage, the one with the introduction dts cleaning water required facility is provided.

The present invention is therefore based on the object of a cleaning device of the type mentioned at the beginning To create a way in which the water or air /: ufuhrleitung takes place in a simple manner, in particular where no special facilities are required on the bridge.

According to the invention this object is achieved in that the water or air supply line is more flexible Drag hose is formed, which is arranged in a in the upper area on a Länaswand of the basin and the cage which extends essentially over the length of the pool lies, with the Water or air connection is at least near the cage.

By the drag hose according to the invention and the arrangement of the water or air connection in or near

the cage, separate facilities on the bridge can be omitted. During the movement of the bridge over the basin, the drag hose is either slowly pulled out of the cage or placed in it. It is only necessary to give the cage a height such that the trailing hose corresponds \ speaking of its length and the bending radius for the

[Loop is securely in place.

\ The water or air supply to the cleaning

'i device required facilities can now

arranged as stationary parts next to the basin

the. In this way, they can easily be checked for functionality and maintained. One separate Coiling of the hose on the bridge can be omitted.

A particular advantage of the invention is given

if you use the cleaning device at a bridge

provides construction, which is provided with a cable. Such bridges are like a pulley with a counterweight generally moved back and forth on two ropes above the pool to be cleaned. Such bridges do not require any drives or electrical equipment on the bridge. Would

one in these pool cleaning devices according to the prior art, the known water or Use air supply lines, so would have to be specially designed for this separate drive units on the c * ör bridge a complex energy supply can be arranged.

The invention can also be used very advantageously in underground pools for reasons of Safety special precautions or configurations of a power supply would have to be taken. Through this the inventive solution, as mentioned, no electricity is required on the bridge, such an underground one Basin by the cleaning device according to the invention cheaper and easier in aer Handling and maintenance.

It is advantageous if the water or air connection

j at least approximately in the longitudinal center of the pelvis im

'' Area of the cage is arranged.

This measure means that only half the length of the hose is required.

If in a further embodiment it can be provided that the

the bottom of the cage is inclined towards the water connection.

• · '

This measure prevents the in the drag hose and the associated devices from freezing Prevents the presence of water when there is a risk of frost, because due to the slope, the water can easily Expire way.

So that snow and rain do not cause problems, it can be provided that the bottom of the cage and, if necessary, its side wall is also provided with holes or slots. via these holes or slots water or melted snow can then run off without any problems.

A simple solution for the cage is that it is designed as an angle plate, with a Legs of the plate substantially perpendicular to the container wall and the other leg at a distance from the Container wall and is directed parallel to it upwards.

The cage can either be on in a simple manner attached to the inside or outside of the pool, together with the pool wall results in a U-shaped channel for the tow hose.

The angle plate can easily be a simple wire mesh, e.g. made of structural steel mesh. To simplify maintenance it can be provided that the cage in The area of the water or air connection on the side is open. The cage can also be used at any time as a concrete ring be placed inside or outside the pool. So that the drag hose is not damaged the different travel positions of the bridge can occur in a further embodiment of the invention be provided that the water or air connection can be rotated at least approximately 180 °. This type of connection you will choose in particular if the connection is in the area of the middle of the pool, since in In this case, the drag hose must be moved from one side to the other.

If necessary, the pipe connection piece can also be used can still be rotated on the bridge.

The cleaning device can be used in conjunction with a clearing device or independently use of it.

Another advantage of the solution according to the invention is that the cleaning device in principle

becomes independent of the diameter of the hose. This allows with very large hose diameters and so that a large amount of water can be cleaned, which causes problems if it is wound onto a drum would lead.

The following is an exemplary embodiment of the invention explained in principle in more detail with reference to the drawing.

It shows:

The wastewater basin 1 shown has an inlet and an outlet 3. A bridge 4 is located above the basin with wheels 5 on rails 6 at the edge of the pool over the wastewater basin 1 can be moved. The drive of the bridge 4 can be done in any way. In FIG. 1, a drive via a cable 7 is indicated by dashed lines.
