EXAMPLES
[0015] A fire engine according to an embodiment of the present invention will now be described. Fig. 1 is a schematic diagram of a fire engine, with Fig. 1(a) showing the state in which a fire water tank and other items are installed, and Fig. 1(b) showing the state in which the fire water tank and other items are not installed. Fig. 2 is a plan view of a fire engine, with Fig. 2(a) showing the arrangement of a driving motor, battery, etc., and Fig. 2(b) showing the arrangement of a fire pump, pump motor, etc. Note that some equipment and components have been omitted from each diagram. The fire engine 1 is an electric vehicle (EV) and includes a vehicle driving motor 3 and a driving inverter 4, a cabin 10, a cargo bed 20 provided behind the cabin 10, a cargo room 21 provided in the cargo bed 20, a fire pump 30 that discharges fire extinguishing water, a pump motor 40 that drives the fire pump 30, a pump motor inverter 50 used to drive the pump motor 40, a plurality of batteries 60 that supply electricity to the driving motor 3 and the pump motor 40, a substantially rectangular fire extinguishing water tank 70 provided in the cargo bed 20 to store fire extinguishing water, a suction pipe 80 used when the fire pump 30 sucks water from an external water source, and a circular suction pipe winding device (hose reel) 90 around which the suction pipe 80 is wound. The cabin 10 includes a front cabin 11 in which a driver's seat and a passenger seat are provided, and a rear cabin 12 in which a rear seat is provided. The front wheels 2A are located below the front cabin 11. A drive shaft 5 is connected to the driving motor 3, and the rear wheels 2B are driven via a differential 6. Although the fire engine 1 can also be an engine-driven vehicle, by making it an electric vehicle as in this embodiment, it is possible to reduce the environmental load and noise compared to engine-driven vehicles.
[0016] The fire pump 30 and the pump motor 40 are mounted via a subframe 23 on a chassis frame 22 arranged on the cargo bed 20. The fire pump 30 and the pump motor 40 are connected in series with the fire pump 30 on the front side and the pump motor 40 on the rear side. The left and right sides of the fire pump 30 are each provided with three discharge ports 31 and one side suction port 32. In addition, one front suction port 33 is provided on the front side of the fire pump 30. The side suction port 32 can also be used as a relay port.
[0017] The multiple batteries 60 are disposed between the chassis frames 22 or to the sides of the chassis frames 22, and the top surfaces of the batteries 60 are lower than the top surface of the chassis frames 22.
[0018] The fire water tank 70 is disposed above the fire pump 30, and the suction pipe take-up device 90 is installed upright between the cabin 10 and the fire water tank 70 with its axis of rotation in the front-rear direction of the vehicle. The rear end of the suction pipe 80 wound around the suction pipe take-up device 90 is connected to the front water inlet 33 of the fire pump 30 via a water suction pipe 100 provided in the center of the suction pipe take-up device 90.
[0019] Shutters are provided as doors that can be opened and closed from above and below on both sides and the rear of the luggage compartment 21. The luggage compartment 21 is closed on the front side of the portion where the suction tube winding device 90 is installed by the back panel of the rear cabin 12, and becomes a closed space when the shutters on both sides and the rear are lowered. The fire extinguishing water tank 70 is installed in a position where there is a shutter on the side in the luggage compartment 21. An opening is formed in the ceiling panel 21A of the luggage compartment 21 at a position corresponding to above the fire extinguishing water tank 70, and an upper surface 71 of the fire extinguishing water tank 70 is exposed from the opening in the ceiling panel 21A of the luggage compartment 21.
[0020] Figure 3 shows the waterproofing and drainage structure at the top of the fire water tank, where Figure 3(a) is an underside view of the fire engine, Figure 3(b) is a side view of the fire engine, Figure 3(c) is an AA cross-sectional view, and Figure 3(d) is a BB cross-sectional view. The fire extinguishing water tank 70 is made of, for example, resin or metal, has a substantially rectangular shape, and the upper ends of the four side plates 72 are several centimeters higher than the top surface 71, which is lower than the ceiling plate 21A. The upper ends of the side plates 72 are located near the rear surface of the ceiling plate 21A, and packing 111 is provided as a sealant between the upper ends of the side plates 72 and the ceiling plate 21A.
[0021] The portion of the side plate 72 that protrudes above the upper surface 71 functions as a damming material 112 that blocks the water on the upper surface 71 from flowing to the side of the fire water tank 70, and this damming material 112 and packing 111 constitute a waterproof material 110 that prevents water from entering the cargo compartment 21. By providing the waterproof material 110 at the opening to make the ceiling of the cargo compartment 21 watertight, when fire water, rainwater, or the like falls on the upper surface 71 of the fire water tank 70 exposed at the opening, the damming material 112 erected on the periphery of the upper surface 71 and the packing 111 arranged thereon act as a wall to prevent water from entering the cargo compartment 21. This makes it possible to prevent water from splashing on the equipment and materials in the cargo compartment 21 without providing a waterproof bulkhead around the fire water tank 70 as in the conventional case. As a result, the space that was previously used for waterproof bulkheads can now be used for installing other equipment or as storage space for materials and equipment. In addition, when the fire engine 1 is traveling, the cargo compartment 21 and the fire water tank 70 swing separately. However, by constructing the waterproof material 110 with the damming material 112 and the gasket 111 as in this embodiment, even if the size of the gap between the fire water tank 70 and the ceiling panel 21A changes slightly due to the swinging during travel, the waterproof material 110 is not affected and the watertightness of the opening can be maintained.
[0022] The ceiling panel 21A has a drooping portion 21Aa bent downward around the periphery of the opening. The drooping portion 21Aa is approximately parallel to the side panel 72 of the fire extinguishing water tank 70, and its lower end is located near the upper surface 71 and lower than the upper end of the side panel 72. By hiding packing 111 from the outside by hanging portion 21Aa in this manner, packing 111 can be protected from sunlight, collisions with objects, and the like, and deterioration and damage to packing 111 can be suppressed.
[0023] Since the upper surface 71 of the fire extinguishing water tank 70 is lower than the ceiling board 21A and a waterproof material 110 is provided at the opening, fire extinguishing water, rainwater, etc. accumulate on the upper surface 71 of the fire extinguishing water tank 70. Therefore, drainage ports 120 are provided at the four corners of the upper surface 71 of the fire extinguishing water tank 70. The drainage ports 120 penetrate the side plate 72, with their outlets located inside the luggage compartment 21, and the upper end of a discharge pipe 121 such as a flexible tube is connected to the outlet. The discharge pipe 121 is disposed in the vertical direction along the fire extinguishing water tank 70, and its lower end is located below the loading platform 20 outside the luggage compartment 21. This allows water accumulated on the upper surface 71 of the fire extinguishing water tank 70 to be discharged outside the vehicle while preventing water from entering the luggage compartment 21.
[0024] FIG. 4 is a side view of the fire water tank. Plates 130 are attached by bolts or the like to the surfaces of the left and right side panels 72 of the fire water tank 70. The plates 130 are used to install equipment holders such as brackets to be used when storing equipment such as fire pump-related equipment, firefighting equipment, or tools, on the sides of the fire water tank 70. This allows the sides of the fire water tank 70 to be effectively used as equipment storage areas.
[0025] The plate 130 is provided with a plurality of fixing parts 131 used for fixing the tool trays, and the fixing part 131 can be selected according to the shape of the tools to be stored, and the multiple tool trays can be appropriately installed on the selected fixing part 131. This makes it easy to store multiple tools together on the side of the fire water tank 70. The material and shape of the plate material 130 and the fixing portion 131 may be selected arbitrarily, but in this embodiment, a perforated metal with a plurality of round holes is used as the plate material 130, and the fixing portion 131 has a plurality of holes. Since the perforated metal has a large number of holes, the fixing portion 131 can be selected from a wider range of options, making it easier to arrange the tool receiver.
[0026] Below the fire extinguishing water tank 70 are arranged a control panel 140 for the fire pump 30 and a ball cock control handle 34 used to open and close the discharge port 31 and side intake port 32. 5 is a diagram showing the operation panel in an open state. The operation panel 140 has an upward-opening door, and when the operation panel 140 (upward-opening door) is opened, equipment that is used less frequently, such as a tank drain valve located in the pump room, and an inspection hatch are revealed.
[0027] FIG. 6 is a diagram relating to the wiring guide, where FIG. 6(a) shows the position of the wiring guide in the luggage compartment, FIG. 6(b) shows a cross section of the wiring guide, and FIG. 6(c) shows an inspection hatch for the wiring guide. A wiring guide 160 is provided on the rear side of the shutter drum 150 at the top of the luggage compartment 21. The wiring guide 160 collectively accommodates wiring connected to the operation panel 140 of the fire pump 30 and the like. Additionally, a plurality of inspection hatches 161 are provided in the ceiling portion of the luggage compartment 21, through which the wiring housed in the wiring guide 160 can be accessed. Note that since the inspection hatches 161 are located outside, they are usually covered.
[0028] FIG. 7 is a view showing the rear part of the luggage compartment. An electric light display 170 that displays various information is provided at the upper rear portion of the luggage compartment 21. A fire extinguishing robot 180 and the like are loaded inside the rear shutter of the luggage compartment 21. [Explanation of symbols]
