Abstract

A graffiti prevention apparatus for preventing application of graffiti to a surface(s). The apparatus includes a control component (11) coupled to one or more modular components (21, 31). The control component (11) has a solenoid valve (12) which is coupled to a liquid supply. A motion sensor (19) upon sensing movement near surface(s) activates the solenoid valve (12) to cause liquid to flow from a supply line (13) to spray pipes (14) so that liquid issues from spray producing nozzles (15, 16) onto the surface(s) to prevent graffiti from being applied to surface(s)

Claims

1. A graffiti prevention apparatus comprising:

a motion sensing means configured to sense the presence of a person prior to arrival at a guided wall section to which the apparatus is mounted,

a controllable valve for a liquid supply,

a supply line coupled to an inlet of the controllable valve and configured to be capable of being coupled to a pressurized liquid supply

a spray line coupled to an outlet of the valve, and

a plurality of nozzles coupled to the spray line and comprising;

at least one mist producing nozzle configured for creating a mist near the guarded wall section for diluting a paint spray; and

at least one spray producing nozzle configured for generating a liquid spray that creates a run-off down the guarded wall section to prevent paint from the paint spray adhering to the guarded wall section;

wherein the controllable valve is configured to be operable to the motion sensing means to permit the flow of fluid from the supply line to the spray line.

3. The apparatus as claimed in claim 1 wherein the pressurized liquid supply is supplied to the mist producing nozzles at a pressure of between 100 and 135 psi.

4. The apparatus as claimed in claim 1 wherein pressurized liquid supply is supplied to the spray producing nozzles at a pressure of between 20 and 80 psi.

5. The apparatus as claimed in claim 1 wherein each of the supply line comprises a pressure manifold and is of a greater diameter than that of the spray line.

6. The apparatus as claimed in claim 1 wherein the apparatus also comprises a liquid storage tank and a pump configured to supply the pressurized liquid supply to the spray line.

7. The apparatus as claimed in claim 1 wherein at least the spray pipe and valve are housed within a cover to form a control component, the cover having openings through which spray issuing from the nozzles can exit the cover.

8. The apparatus as claimed in claim 7 wherein one or more modular components comprising a cover, spray pipe and spray producing nozzles are connected to the control component.

9. The apparatus as claimed in claim 7 wherein the covers of adjacent control component and modular components are coupled together.

10. The apparatus as claimed in claim 8 wherein one or more of the modular components include a supply line coupled together to the supply line of the control component.

11. The apparatus as claimed in claim 1 wherein the spray producing nozzles and the mist producing nozzles are interspersed along the spray pipe.

12. The apparatus as claimed in claim 1 wherein the spray producing nozzles and mist producing nozzles are arranged in repeating groups with each group consisting of a mist producing nozzle located between a pair of spray producing nozzles.

13. The apparatus as claimed in claim 1 further comprising one or more lights coupled to and activated by the motion sensing means.

14. The apparatus as claimed in claim 1 further comprising an audible alarm activated by the motion sensing means.

15. The apparatus as claimed in claim 1 further comprising a camera activated by the motion sensing means.

16. The apparatus as claimed in claim 1 further comprising a water meter fitted to the supply line.

17. The apparatus as claimed in claim 1 further comprising a timer fitted to the motion sensing means.

18. The apparatus as claimed in claim 1 further comprising an isolating valve fitted to the supply line.

19. The apparatus as claimed in claim 1 further comprising a filter fitted between the isolating valve and the supply line.

2. A graffiti prevention apparatus comprising:

a motion sensing means configured to sense the presence of a person prior to arrival at a guided wall section to which the apparatus is mounted,

a controllable valve for a liquid supply,

a supply line coupled to an inlet of the controllable valve and configured to be capable of being coupled to a pressurized liquid supply

a spray line coupled to an outlet of the valve, and

a plurality of nozzles coupled to the spray line and comprising;

at least one mist producing nozzle configured for creating a mist near the guarded wall section for diluting a paint spray; and

at least one spray producing nozzle configured for generating a liquid spray that creates a run-off down the guarded wall section at a flow rate of at least 2 m/s to prevent paint from the paint spray adhering to the guarded wall section;

wherein the controllable valve is configured to be operable to the motion sensing means to permit the flow of fluid from the supply line to the spray line.
