This idea or concept is strongly bound to necessity is the mother of invention.
Four years back travelling on my Travera from B’lore to Chennai experienced heavy rain fall in some sectors. Whenever overtook a heavy vehicle the muck got sprayed on to the windscreen by the vehicles tire. I had to periodically use the water from the wiper tank to clean and after sometime the water in the tank got exhausted.
Driving after that became really difficult and had to stop by a shop bought water and filled up my wiper tank.
I thought so much rain and my wiper (1 ltr) is empty.
In most of the vehicles where the wind shied ends and the bonnet starts there is a black grill, the purpose is to drain out the rain water.
So when I was back in B’lore went to my friend’s garage and fitted a rectangle container below the grill and connected a small tube to my windshield wiper tank.
After that my wiper tank was never empty.
Later made a sliding lid for the container and hooked it with springs. The lid had a cable which was drawn to my dashboard. The reason for the lid was to prevent dust accumulating on dry days. Whenever it used to rain just pulled the cable so that the lid slides open.
Then started thinking about buses, trucks, trailers and trains.
Storage of Water in Buses
This principle can be adapted to the above as their requirement of water is heavy.
Travelling from Coimbatore to Chennai the driver stopped the bus and cleaner here is pumping water from the hand pump and storing it. Asked the driver is it such an emergency that you have stop the bus to collect water. He replied “Sir if a gasket gets cut I can replace the gasket in 15min and always carry a spare one but will need at least 45 ltrs of water. Then I noticed most of the buses were storing water, but each driver gave a different reason. The fact remains that there was req of water.
So came with the design which incorporates external filling and rain water harvesting.
There are two channels called the rain gutters on top of a bus which collects rain water and flows down to the holding tank and to the windshield wiper tank which is in the front.
A pump is fixed to the tank and piping system runs at the base of the bus with seven outlet nozzles. A hose can be attached to these nozzles and can be used for cleaning the bus.
An external water inlet pipe is attached to the tank so that on a dry day it can be filled up by manual means.
Over flow pipes are fixed to the tank
1 - Rain Gutter2 - Water Holding Tank3 - Windshield Wiper Tank
4 - Rain Water Inlet Pipe
5 - External Water Inlet Pipe6 - Vent Pipe7 - Overflow Pipe8 - Pump
9 - Outlet Nozzles
In the recent incident of bus catching fire I incorporated a fire sprinkler system.
Combined Design of Rain A-Gain & Fire Safety
1 - Fire Pump2 - Dedicated Power Supply3 - Fire Tank4 - External Water Inlet Pipe
5 - Vent Pipe6 - Fire Piping7 - Sprinklers
There are two tanks one is fire reserve tank and other is domestic tank. Manual filling or rainwater flows to the fire tank and the overflow of fire tank is connected to domestic tank.So at any given time the fire tank is full. A fire pump is connected to fire tank which has a dedicated power supply (not from the bus), Sprinklers piping system is driven by the fire pump and sprinklers are located above diesel tank, engine and runs at the ceiling of the bus and can be strategically located based on safety just like any fire protected building.
The same principle can be adopted for any automobile and trains.
In a train there is one tanker which acts as a water carrier for Fire Reserve and there is on small compartment ( like a guard bogie) which houses a fire pump and the piping runs on top of the coaches and at strategic places concealed sprinklers drop down. Smoke detectors are also installed to detect smoke and fire which triggers the alarm.
Basic Design is given below.
This will address the issue of Fire Safety and Rain water harvesting can also be incorporated in trains like buses and goods carrier
