Description

FIELD OF INVENTION

The present invention relates to a bulldozer, and more particularly, the present invention relates to an apparatus for a bulldozer that aids in controlling the fire and protects the dozer from fire.

BACKGROUND

Wildfires, also known as forest fires, are a grave natural disaster that destructs the landscape, lives, and property. Besides the damage and destruction caused by uncontrolled and massive wildfires, the release of greenhouse gases significantly contributes to global warming. So, there is an opportunity to limit the spread of wildfire and prevent further damage and destruction to the environment, property, and lives by utilizing these bulldozers with the fire apparatus designed especially for bulldozers to be retro fitted with.

Fighting wildfire is difficult due to the massiveness of fire, several obstacles, and challenging forest terrain. For these reasons, firetrucks are unable to reach the some sites of fire. Bulldozers are common in controlling the wildfires. Bulldozers can move on the rough terrains and make a fire line to prevent the spread of wildfire. However, the dozers are not adapted for firefighting and suffers from major limitations. Such limitations of the known bull dozers to fight wildfires has resulted in several accidents, some with death.

Thus, a need is appreciated for improvements in the bulldozers to overcome the previously mentioned limitations. A need is appreciated for an apparatus for a dozer that can make the wildfire fighting more effective and safer.

Disclosed is an apparatus for a bulldozer that allows making the bulldozers safer and more effective in controlling the wildfires. Also, disclosed are the bulldozers with the disclosed apparatus. The disclosed bulldozer includes all the advantages of a conventional bulldozer including bush clearing and bull dozing functions of a crawler-type tractor. The apparatus allows using water to extinguish the fire and save the dozer from fire damage. The apparatus allows for stably holding large capacity of water in a water tank without wobbling and effecting the operation of the dozer on rugged terrain. The disclosed dozer can extinguish the fire spreading to the Fireline using water or similar fire retardant. The fire reaching the Fireline can harm both the fire dozer and the operator of the bulldozer, and by extinguishing the fire, the disclosed apparatus can safeguard the bulldozer and the operator. Moreover, preventing the fire from escaping containment lines is critical to shortening and reducing fire size. The disclosed apparatus can include the functionality of a fire truck by accommodating large water tanks, high power water pump, hose reels, hose manifolds, fire monitors, and side sprays. Besides water, the apparatus may also allow applying suitable fire retardants known for use in controlling and extinguishing wildfires.

Referring to FIGS. 1 and 2, the apparatus can include a pump 1. The pump can be a high-pressure pump suitable for firefighting and can be installed in front or side of an operator cabin door, or entrance to the bulldozer. The input of the pump can be connected to a water tank 8 through a suitable conduit. In one implementation, the pumps can deliver at least 200 PSI so to pump water uphill to a fire that is several hundred feet higher than the dozer. The pumps can be mounted on a custom build hinged steel platform 1a that will allow the pump to swing away providing access to the dozers internal hardware for maintenance when needed. The hinge 1b can be used to mount the pump. The pumps can be covered by a steel cover attached to the swing platform protecting the pump from tree or brush damage.

The water tank can be mounted on a rear of the dozer. FIGS. 1 and 2 shows a large capacity tank mounted to a rear end of the dozer using a Bolt on Brackets on tank to dozer 11. It is understood, however, that any other brackets and supports can be used to mount the tank depending on the weight of the tank, and any such brackets and supports are within the scope of the present invention. FIG. 1 shows the heavy angle iron protective frame 9 and heavy channel iron bars on sides of tank 10 for support and protection of the tank from external impacts and insults. Any suitable protective frame can be used to protect the tank and shield it from external impacts. On top of the tank can be a filling hole 8a for filling the water into the tank. At the bottom of the tank can be a drain hole 8b for emptying the tank. The size of the tank can be important to hold enough water to be usable for extinguishing any fire reaching the Fireline. At the same time, the size must also not exceed to an extent that disrupt the balance and stability of the dozer. The size of the tank can depend upon the size of the dozer. The tank can be made from a heavy steel plate. Suitable numbers of baffles can be provided inside the tank to reduce water movement preventing any wobbling that may destabilize the dozer. The tank can be made from a water-resistant material. Alternatively, a coating can be provided at least on the inner surface of the tank that prevents any kind of corrosion, such as a rust preventive coating. The conduit connecting to the bottom of the tank can also be galvanized to keep corrosion to a minimum.

Connected to the pump can be a custom-built water pipe assembly that can be custom fitted for each dozer to deliver water to one or more hose reels 2 mounted on one or more locations on the dozer but typically on the sides of the dozer. The hose reels can typically carry at least 100 feet of hardline hose with a hose nozzle appended that fire personnel can use to put out fires. FIG. 2 shows two hose reels on the left and right side of the dozer present at the engine compartment doors. Valves 2a can be used to turn on and off the water supply to different hose reels.

FIG. 3 shows the hose reels 2 in a protective hose reel steel cabinets 13 that are mounted on a hose reel platform 3 and a platform hinge 3a can couple the hose reel platform 3 to the dozer. The hose reel cabinets can swing out of the way to allow access to the engine compartment for maintenance and repairs.

The apparatus can further include a single monitor 4 that can be mounted on top of the engine hood forward of the Exhaust Stack. The monitor can be coupled to a control unit that can connect to different components of the dozer and the apparatus for receiving the input. The control unit can be remotely controlled. The control unit can be connected to the pump, water tank, hose reels. The level of water in the water tank can be read by a sensor that provides the reading to the control unit and the same can be displayed on the monitor. Similarly, the status and use of hose reels can be shown on the monitor. The monitor can be positioned in line with the exhaust stack so as not to compound and obstruct the operators view.

The apparatus can further include Fire hose manifolds 12 with 1.5-inch fire hose outlet 12a and 1.0-inch fire hose outlets 12b, both with the valves, and can be installed adjacent to the hose reels. The apparatus can further include sprinklers/nozzles that may be arranged on distinct positions of the dozer such that to spray water on the ground (Fireline) around and nearby the dozer, such as surroundings of the dozer. The nozzles can also spray water on body of the dozer as a safeguard against fire damaging the dozer. The operation of these spray nozzles/sprinklers can be controlled by the control unit in the operator's cabin.

While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
