Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The above-described properties, features and advantages of this invention and the way in which they are achieved will become more clearly and obviously comprehensible in association with the following description of the exemplary embodiments, which are explained in more detail in association with the drawings, in which:

[0025] FIG. 1 shows an anchoring unit with two screws, two insulation layers, a base layer and an insulation sleeve;

[0026] FIG. 2 shows a system with an anchoring unit and an electrolysis module.

DETAILED DESCRIPTION OF INVENTION

[0027] FIG. 1 shows an anchoring unit 1 with a first insulation layer 4 and a second insulation layer 5. A base layer 6 is arranged between the first insulation layer 4 and the second insulation layer 5. A first screw 2 is fastened to the base layer 6. The first screw 2 penetrates the first insulation layer 4. It is therefore at least partially arranged in the first insulation layer 4. A second screw 3 is likewise fastened to the base layer 6. The second screw 3 is fastened to the base layer 6 in the opposite direction to the first screw 2. The second screw 3 penetrates the second insulation layer 5. The second screw 3 is therefore at least partially arranged in the second insulation layer 5.

[0028] The first insulation layer 4, the base layer 6 and the second insulation layer 5 are surrounded by a cover 7. The second screw 3 is fixedly connected to an anchor object 8. The anchor object 8 is typically the ground. However, it is likewise possible that the anchor object 8 may be a wall or a fixed component. The first screw 2 is surrounded by an electrical insulation sleeve 10 in the region of the first insulation layer 4 and the base layer 6. The screw head of the first screw 12 is furthermore separated from the base layer 6 by an insulating flat washer 9. Electrical insulation of the first screw 2 from the second screw 3 therefore advantageously takes place if the base layer 6 is conductive. The first screw 2 in this exemplary embodiment is countersunk in a depression in the base layer 6.

[0029] The insulation sleeve 10 can firstly be introduced into a cutout in the insulation layers and the base layer 6. The screw can subsequently be screwed into the insulation sleeve 10. It is alternatively conceivable that the screw 2 is firstly inserted into the insulation sleeve 10 and subsequently pushed through the base layer 6 and the first insulation layer 4.

[0030] An insulating flat washer 9 is arranged between the screw head of the first screw 12 and the base layer 6. This flat washer prevents contact between the screw head 12 and the base layer 6. The first screw head 12 has a diameter which is smaller than the depression in the base layer 6. In other words, an electrically insulating air space is present between the first screw head 12 and the base layer. Electrical insulation of the first screw from the second screw is therefore advantageously ensured.

[0031] To ensure electrical insulation within the anchoring unit, it can be sufficient for only one of the screws to be arranged in an insulation layer. In particular, it is possible for only the first screw 2 to be arranged in the first insulation layer 4 and the insulation sleeve 10. The first and/or second insulation layer 4, 5 can furthermore be designed as a washer around the screw.

[0032] The cover 7 is water-tight and electrically insulated. In this exemplary embodiment, the first insulation layer 4 has cutouts at the point at which the screw head of the first screw 12 dips into the insulation layer 4. The cover 7 can therefore advantageously cover, and therefore likewise electrically insulate, the entire screw head. Both the screw shaft of the first screw 14 and the screw shaft of the second screw 15 are at least partially surrounded by an insulation layer. The first screw 2 is thus advantageously electrically insulated from the second screw 3. The cover 7, which is water-tight and electrically insulating, advantageously prevents water from penetrating into the anchoring unit 1, whereby short circuits are prevented.

[0033] The screws typically comprise materials consisting of metal. The cover in particular comprises materials which have rubber-elastic properties. These may be in particular acrylonitrile butadiene rubber (NBR), ethylene propylene diene monomer rubber (EPDM) or fluororubber (FPM). The first insulation layer 4 and the second insulation layer 5 in particular comprise materials such as thermosetting plastics or hard paper materials. The base layer 6 in particular comprises materials such as metals, which have a high strength and resilience.

[0034] Only half of the anchoring unit 1 is illustrated in FIG. 1. The axis of mirror symmetry shows that the anchoring unit 1 has two first screws 2 and two second screws 3 in each case. The overall construction is made clear in FIG. 2.

[0035] FIG. 2 shows a system unit 100 with an anchoring unit 1 and an electrolysis module 20 as a system. The construction of the anchoring unit 1 corresponds to the construction of the exemplary embodiment of FIG. 1. The anchoring unit 1 here is fixedly connected to the ground as an anchor object 8. The two first screws 2 are fixedly connected to the electrolysis module 20. An electrolysis module 20 is typically connected to two anchoring units. In the event that the electrolysis module 20 applies tensile loads to the anchoring unit 1, in particular due to oscillations or vibrations, electrical insulation through the anchoring unit to the ground is advantageously ensured. In the event that water escapes from an electrolysis module 20, a short circuit via the anchoring unit 1 can also be prevented owing to the arrangement of the insulation layers, the cover and the screws.

[0036] Although the invention has been described and illustrated in greater detail by way of the preferred exemplary embodiment, the invention is not restricted by the disclosed examples and other variations may also be derived therefrom by a person skilled in the art without departing from the scope of protection of the invention.
