Description
Potable Water Service Vehicle
FIELD OF THE INVENTION
This invention relates to a potable water service vehicle for servicing an aircraft.
BACKGROUND OF THE INVENTION
Potable water service vehicles are in daily use at airports worldwide for replenishing the potable water tanks of all aircraft types. Potable water service vehicles comprise a potable water storage tank typically mounted on a chassis of a commercial vehicle, wherein the water storage tank can be filled with potable water and the vehicle driven to a position adjacent an aircraft to enable fresh potable water to be pumped into the aircraft potable water tank. An operator's platform is typically provided on a rear end of the vehicle, mounted on a lifting mechanism whereby the operator's platform can be raised to allow an operator to connect a water supply pipe from the storage tank to the filler of the aircraft tank.
Typically, the water storage tank has a filler located on one side of the vehicle to allow the tank to be filled with water, an overflow pipe being associated with the filler extending from an upper region of the storage tank and terminating above the ground. During filling, the operator typically supplies water into the filler until water overflows from the overflow pipe, indicating that the storage tank is full. The overflow pipe also serves as a vent to allow air to escape from tank as it is filled.
A problem with known potable water service vehicles is that water tends to spill out of the tank via the overflow pipe as the vehicle is driven, particularly when changing direction away from the side of the tank upon which the overflow pipe is provided. While not toxic, the spillage of potable water onto the airport apron can cause slip hazards. An object of the present invention is to overcome this problem by preventing spillage from the tank of a potable water service vehicle as it is driven on the airport apron.
SUMMARY OF THE INVENTION
According to the present invention there is provided a potable water service vehicle comprising a wheeled chassis, a potable water storage tank mounted on the chassis; a filler pipe being provided at a forward end of the water storage tank on one side of the vehicle chassis to allow the potable water storage tank to be filled from a suitable water supply; an overflow pipe being provided adjacent the filler pipe, said overflow pipe extending downwardly and terminating beneath the water storage tank; a closure valve being provided in the overflow pipe to allow the overflow pipe to be selectively closed, said closure valve being adapted to close said overflow pipe when the wheeled chassis is moving to prevent spillage of water from said overflow pipe; at least one air vent being provided in a central region of an upper wall of the water storage tank to prevent the formation of a partial vacuum in the water storage tank when the closure valve of the overflow pipe is closed.
13 An actuator may be provided for operating the closure valve. In one embodiment the actuator may comprise an electrically controlled pneumatic actuator. Preferably the actuator of the closure valve is associated with a hand brake of the vehicle adapted to selectively lock one or more wheels of the vehicle, whereby the closure valve is automatically opened when the hand brake of the vehicle is engaged, the closure valve being automatically closed when the hand brake is released. The actuator may be electrically controlled via a switch associated with the hand brake of the vehicle, said switch being used to operate a warning light to indicate that the hand brake is engaged.
The water storage tank may comprise a rectangular upper wall, vertically depending side and end walls and a trough shaped bottom wall. The filler pipe may extend upwardly and outwardly from the upper wall of the tank. The overflow pipe may extend forwardly and downwardly from a front wall of the tank adjacent the upper wall of the water storage tank, below the filler pipe, to terminate below or adjacent the bottom wall of the tank.
One or more access doors may be provided in the upper wall of the water storage tank to permit access to the interior of the tank for cleaning and maintenance.
The filler pipe may terminate in a removeable cap for closing the filler pipe.
An operator's platform may be mounted on one end of the chassis via a lifting mechanism whereby the operator's platform can moved from a lowered transport 5 position and a raised operating position to allow an operator to couple of water delivery hose of the water storage tank to an aircraft potable water tank.
The closure valve may comprise a ball valve The at least one air vent may comprise an upwardly extending tube extending from a respective aperture in the upper wall of the tank, a cap being provided over the top of the tube of the or each vent to prevent dirt or debris or other contaminants from entering the or each vent while allowing air to enter and exit the or each vent. The cap of the or each air vent may comprise a dome shaped cap located over an opening of the or each vent.

A potable water service vehicle in accordance with an embodiment of the present invention will now be described, by way of example only, with reference to the 25 accompanying drawings, in which: Figure 1 is a perspective view of a potable water service vehicle in accordance with an embodiment of the present invention; Figure 2 is a plan view of the potable water service vehicle of Figure 1; Figure 3 is a side view of the potable water service vehicle of Figure 1; Figure 4 is an end view of the potable water service vehicle of Figure 1; Figure 5 is a side view of the potable water service vehicle of Figure 1 with the operator's platform in a raised position; Figure 6 is an end view of the potable water service vehicle of Figure 1 with the operator's platform in a raised position; Figure 7 is a detailed perspective view of the potable water storage tank of the vehicle of Figure 1; and Figure 8 is a side view of the potable water storage tank of the vehicle of Figure 1.
DETAILED DESCRIPTION OF THE DRAWINGS
As illustrated in Figures 1 to 6 a potable water service vehicle in accordance with an embodiment of the present invention comprises a self-propelled wheeled chassis 2 having a driver's cab 4 at a front end and a potable water storage tank 6 mounted on the chassis 2 behind the driver's cab 4, an operator's platform 8 being mounted on a rear of the chassis 2 via a lifting mechanism 10 whereby the operator's platform 8 can moved from a lower transport position, as shown in Figures 1 to 4, and a raised position, as shown in Figure 5 and 6.
The water storage tank 6 has a rectangular upper wall, vertically depending side and end walls and a trough shaped bottom wall.
A water delivery hose 12 extends between the water storage tank 6 and the operator's platform 8 via a pump 14, whereby the water delivery hose 12 can be coupled to a potable water tank of an aircraft and the aircraft tank can be filled with water from the water storage tank 6 via said pump 14.
A filler pipe 16 is provided at a forward end of the water storage tank 6 extending upwardly and outwardly from the upper wall of the tank 4 on one side of the vehicle chassis 2 to allow the potable water storage tank 6 to be filled from a suitable water supply. The filler pipe terminates in a removeable cap 18 and leads into an upper region of the tank 6.
An overflow pipe 20 is provided adjacent the filler pipe 16, extending forwardly from a front wall of the tank adjacent the upper wall of the water storage tank 6, below the filler pipe 16, said overflow pipe 20 extending downwardly and terminating beneath the water storage tank 6, the overflow pipe 20 serving as an indicator that the tank is full (when water passes out of the overflow pipe 20).
112 Access doors 22,24 are provided in the upper wall of the water storage tank 6 to permit access to the interior of the tank for cleaning and maintenance.
A closure valve 26, which may be in the form of a ball valve, is provided in the overflow pipe 20 to allow the overflow pipe to be selectively closed. An actuator 28, 15 for example an electrically controlled pneumatic actuator, is provided for operating the closure valve 26.
In a preferred embodiment the actuator 28 of the closure valve 26 is associated with a hand brake of the vehicle adapted to selectively lock one or more wheels, for example the rear wheels, of the vehicle, such that the closure valve 26 is automatically opened when the hand brake of the vehicle is engaged, the closure valve 26 being automatically closed when the hand brake is released. The operation of the closure valve 26 as a function of the operation of the hand brake of the vehicle ensures that the overflow pipe of the water storage tank is closed when the vehicle is moving (i.e. when the hand brake is released), preventing water from overflowing from the overflow pipe 20 due to movement of the water within the tank 6 as the vehicle is driven around. The closure valve 26 of the overflow pipe 20 is opened when the vehicle is stationary to enable the overflow pipe 20 to be used to indicate when the water storage tank 6 has been filled during filling with water via the water storage tank filler pipe 16. The actuator 28 may be electrically controlled via an existing switch provided on the vehicle and associated with the hand brake of the vehicle and used to operate a dash board warning light in the driver's cab 4 to indicate that the hand brake is engaged.
To prevent the formation of a partial vacuum in the water storage tank 6 when the closure valve 26 of the overflow pipe 20 is closed, a pair of air vents 30,32 are located in a central region of the upper wall of the tank 6. Each air vent 30,32 comprises an upwardly extending tube extending from a respective aperture in the upper wall of the tank, a dome shaped cap 34,36 being provided over the top of the tube of each vent 30,32 such that the caps 34,36 prevents dirt or debris or other contaminants from entering the vents 30,32 while allowing air to enter and exit each vent 30,32.
The air vents 30,32 are located in a central region of the upper wall of the tank 6 so that water cannot escape from the vents 30,32 as the vehicle is driven around and the water sloshes around and moves to the side walls of the tank 6 under inertia.
The invention is not limited to the embodiment described herein but can be amended or modified without departing from the scope of the present invention as defined by the following claims. For example, the potable water storage tank may be mounted upon a wheeled chassis defining a trailer to be towed behind another vehicle rather than one a self-propelled chassis or truck as described above.
