Flexible shaft for cleaning purposes with internal water supply

Abstract

Flexible shaft with water supply, characterized in that the water supply to the cleaning brush runs inside the protective hose 6 and around the shaft core 1.

Description

[0001] Flexible shaft with internal water supply can be used to clean inaccessible areas where deflection and bending of the cleaning brush with water supply is required.

[0002] The advantage of the system is that the water supply takes place inside the flexible shaft.

[0003] Existing pole cleaning systems with water supply have the disadvantage that they are rigid and the water supply is external via a separate hose.

[0004] This means that cleaning can only be carried out on flat surfaces.

[0005] The solution according to the invention creates a device which, with the flexible shaft, is a movable drive part for the cleaning brush.

[0006] Which is connected to a remote motor and can therefore also be used in potentially explosive rooms, sites and containers.

[0007] Thanks to the internal water supply, the entire system remains flexible and does not require an additional external water supply.

[0008] The invention will be explained in more detail using an exemplary embodiment: Fig. Figure 1 shows the flexible shaft in cross-section. Fig. 2: shows the flexible shaft with water and cleaning hose

[0009] The solution according to the invention consists of: 1 wave soul 2 compressed air distributors 3 shaft core coupling 4 Sleeve 5 pipe 6 Protective hose 7 Multi-sleeve 8 snap rings 9 Claw 10 deep groove ball bearings 11 Cleaning agent connection; which is closed when not in use. 12 Water connection 13 Water outlet opening 14 Tool connection, preferably for a cleaning brush

[0010] If water is supplied via the water connection 12 and, if necessary, cleaning agent is also added, the water jet emerges from the water outlet opening 13 under the existing water pressure, via the cleaning brush (not shown).

Claims

[1] Flexible shaft with water supply, characterized by that the water supply to the cleaning brush runs inside the protective hose 6 and around the shaft core 1. [2] Flexible shaft according to claim 1, characterized by that in addition to the water connection 12, a cleaning agent connection 11 is also provided. [3] Flexible shaft according to claim 1 and 2, characterized by so that the water connection 12 and the cleaning agent connection 11 can be optimally connected, as close as possible, to the water supply. Depending on requirements, the length of the flexible shaft up to the water outlet opening 13 can be small or large. [4] Flexible shaft according to claim 1 and 3, characterized by that the water is directed from the water outlet opening 13 in a ring shape over the brush.
