Description

Australian Patents Act 1990 -Regulation 3.2 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title Self contained maintenance depot The following statement is a full description of this invention, including the best method of performing it known to me/us:- P/00/011 5102 P MWPDOCSLNMSpeUUU6224 EBS AU mmpldc-fliA6(242R 00 -1- SELF CONTAINED MAINTENANCE DEPOT 00 Field of the Invention 00 SThe present invention relates to a depot and a machinery maintenance depot.

00 Background of the Invention Cleaning and maintaining machinery is quite often conducted with low pressure hose cleaning apparatus in open areas, which is ineffective. Further, the equipment is often washed down on concrete slabs, which are permeable and therefore ineffective in containing chemical residues and the removed oils and greases from the equipment.

Further, open air wash down can atomise chemical residues and contamination can spread on the wind. In many current vehicle wash down operations, overspray and spills are generally at risk of soaking into the ground through concrete slabs or they are directed to run into stormwater systems before flowing on to a watercourse or other body of water. It is also difficult to access undercarriage areas of the machinery with the spray apparatus and to check whether the spray apparatus has cleaned those areas of the machinery.

Furthermore, maintenance chemicals and fuel are generally stored and handled in their own respective separate depots with the expectation that only trained personnel may access and handle the chemicals and fuel. If the chemicals are stored in unsuitable areas they can pose a significant risk to industry and the environment. In those situations, spills may not be contained, so that in the event of a spill, wash down liquids may flow into the ground through improperly prepared storage facilities adjacent the chemical and fuel depot or workstation. The delivery of fuels and chemicals is generally made through unprotected means raising the risk of an uncontained spill in the event of a delivery failure.

Generally, maintenance machinery must drive long distances between the cleaning, P:\WPDOCSMLNM\Spcc\2l116124 Bais EBS AU complc do-Ak1/2t8) 00 -2- .s chemical and fuel storage and handling areas to be maintained and to take on payloads of chemicals and fuels.

00 The above-mentioned problems are particularly highlighted in turf management, 00 because of the chemicals used and the particular sensitivity of a turf environment to these Schemicals and management practices.

00 SThe present invention seeks to ameliorate one or more of the abovementioned disadvantages.

Cleaning of the undercarriage 00 00 and other parts of the turf maintenance vehicle may be conducted with the high pressure cleaning means 12 and the spill from the cleaning means simply falls through the elevated Swork zone 16 and into the sump 44. The micro switch within the sump actuates the spill 00 0processing means 18 and the filtered and clean and purified spill is returned to grey water reservoir 28. If there is very little water left in the grey water reservoir 28 it may be supplemented by fresh rain water from reservoir 72. Chemicals may be mixed and diluted with water from the grey water reservoir 28 in the work zone 16. The chemicals may then be loaded onto the turf maintenance vehicle for application to the turf. Chemical spill simply falls through the elevated work zone 16 and is captured and contained by the sump, and if spill capacity exceeds the sump capacity, by the bard wall.

A similar process occurs with the fuel dispensing means Advantageously, the preferred depot in the drawings has the ability to derive energy from the sun through solar panels and store it through battery banks, and to use this energy for lighting. In addition, through complimentary supply of hot water derived from solar means, emulsification rates of oils, greases and chemicals can be accelerated. When combined with the possibility of multiple application of pressure cleaning wands, the productivity of the self contained maintenance facility will be enhanced. The preferred depot shown in the figures is designed to capture rain run off and to utilise this for topping up the self contained, closed loop, water treatment process, as well as for irrigation and fire fighting (bush fires and other fires) purposes.
