<Fire pump truck 10 ₁ according to the first embodiment of the present invention>
FIG. ₁ shows a configuration example of a firefighting pump truck 101 according to the first embodiment of the present invention. Fig. 3 shows a cross-sectional view;

The firefighting pump truck 101 has _a traveling function of the vehicle and includes a truck-type body 11 on which a container can be loaded, a pump unit 20, an equipment unit 30, and a side box 40. _The fire pump truck 101 corresponds to the specially equipped vehicle of the present invention.

A vehicle body 11 has a cabin 12 mounted on a ladder frame 13 . In the example of FIG. 1, the cabin 12 is a double cabin having two rows of seats, but the seats may be in one row including the driver's seat and the passenger's seat, or may be in three or more rows. If more people than the capacity of the cabin ₁₂ are to ride on the fire pump truck 101, seats may be provided in the equipment unit 30 or the like, which will be described later.

The vehicle body 11 is a reciprocating engine vehicle whose power source is gasoline, light oil, etc., as well as an electric vehicle (EV (Electric Vehicle), a hybrid vehicle (HV (Hybrid Vehicle), a plug-in hybrid vehicle (PHV)). A hybrid vehicle), a fuel cell vehicle (FCV (Fuel Cell Vehicle), etc.), and the vehicle body 11 may be an unmanned vehicle capable of fully automatic driving that may appear in the future.

_The vehicle body 11 of the fire pump vehicle 101 has two axles and four wheels, and the drive system may be front-wheel drive, rear-wheel drive, or all-wheel drive.

The housings of the pump unit 20 and the equipment unit 30 are directly mounted on the ladder frame 13 of the vehicle body 11 . Specifically, for example, by aligning the through-hole provided in the lower part of the housing of each unit with the through-hole of the ladder frame 13 and inserting a rod-shaped member into the through-hole, the unit can be easily attached and detached. is placed on. In FIG. 1, the pump unit 20 is arranged on the rear side and the equipment unit 30 is arranged on the front side, but these positional relationships may be exchanged. The side boxes 40 are detachably connected to left and right side surfaces of the ladder frame 13 of the vehicle body 11 .

The pump unit 20 has, for example, a box-shaped housing 29 having an opening (which may be provided with a door that can be opened and closed) that communicates with the inside at least in part, for absorbing or discharging water for extinguishing the fire. The pump 24 (FIG. 2) and the like are stored.

The equipment unit 30 and the side box 40 have, for example, a box-shaped housing having an opening (which may be provided with an openable door) that communicates with the inside at least in part, and various equipment ( It is designed to accommodate an electric submersible pump (EWP) 41, a float type electric pump (FEP) 42, an electric pump (EP) 43, a pipe tip 44, etc. (all are shown in FIG. 3).However, the electric submersible pump 41 and the float The electric pump 42 , the electric pump 43 , the tube tip 44 and the like may be housed in the pump unit 20 .

Further, the equipment unit 30 and the side box 40 may be provided with shelves and partitions so that various equipment can be mounted according to the characteristics and purpose of the area where the fire pump truck ₁₀₁ is deployed. Equipment to be installed is, for example, hydraulic rescue equipment if rescue activities on highways are assumed, backpack-type transport equipment and water rescue equipment if fire fighting and rescue activities in the mountains are assumed. In some cases, an aqualung set is assumed, and in cases where fire-fighting activities in densely populated residential areas are assumed, a large number of hose carriers, etc. are assumed.

Furthermore, the equipment unit 30 may be provided with a seat and a bed so that it can be used as an operation space, a temporary relief space, etc. after arriving at the disaster site.

The interior upper portion of equipment unit 30 houses emergency vehicle equipment 31 including siren 32 , red light 33 , installation base 34 , and movement mechanism 35 . A siren 32 and a red light 33 are installed on the installation base 34 . For example, the moving mechanism 35 is configured by combining a plurality of legs and a rotating shaft, and lifts up the installation base 34 on which the siren 32 and the red light 33 are installed in the forward and downward directions. lift down to The emergency vehicle equipment 31 is normally lifted up by the movement mechanism 35 so that part of it covers part of the cabin 12, but for example the entire cabin 12 is tilted forward for servicing the engine. In this case, the moving mechanism 35 can be lifted down inside the equipment unit 30 so as not to interfere with the cabin 12 . Note that the moving mechanism 35 may move the installation base 34 only in the vertical direction or only in the front-rear direction.

Further, the emergency vehicle equipment 31 may be detached from the equipment unit 30 so that it can be mounted alone on the cabin 12 . A power source for driving the emergency vehicle accessory 31 may be supplied from the outside of the emergency vehicle accessory 31, or a driving battery may be provided inside the emergency vehicle accessory 31.

Further, a display 36 such as an LED panel or a liquid crystal panel may be provided on the side surface or outer periphery of the emergency vehicle equipment 31 . On the display 36, for example, characters such as "first fire brigade" and "disaster dispatch" are displayed. It can be used as a substitute for illumination by calling attention or by lighting with high brightness in white.

The operation control of the emergency vehicle equipment 31, specifically, the lift up/lift down of the moving mechanism 35, the on/off of the siren 32 and the red light 33, is performed by a switch or the like provided in the cabin 12, or by a smartphone or the like. may be remotely controlled using a portable terminal.

A water storage tank may be mounted instead of the equipment unit 30 .

Next, FIG. 2 shows a configuration example of the pump unit 20. As shown in FIG. FIG. 3 shows an example of how the pump unit 20 is used.

The pump unit 20 accommodates a controller 21 , a battery 22 , an electric motor 23 and a pump 24 inside its housing 29 . In addition, the pump unit 20 has a solar panel 28 arranged outside the ceiling of the housing 29 thereof. Note that the solar panel 28 may be arranged on the side surface of the housing 29 or outside the housing of the equipment unit 30 .

The control unit 21 controls an electric motor 23, a pump 24, an electric submersible pump (EWP) 41 (FIG. 3), a float type electric pump (FEP) 42, and an electric pump (EP) 43 (FIG. 3) in accordance with user's operation. to control the operation of This facilitates control when discharging water by relaying a plurality of pumps. Note that the user can operate the control unit 21 on the device side, or, for example, a mobile terminal such as a smart phone may be used to remotely operate the control unit 21 . Further, if the control program inside the control unit 21 is made rewritable, the version of the control unit 21 can be easily upgraded. Of course, the electric submersible pump 41, the float type electric pump 42, and the electric pump 43 may each be provided with a control section separately from the control section 21, and the user may operate them individually.

The battery 22 is, for example, a lithium ion battery, an all-solid battery, or the like, and is charged in advance before dispatch. However, the battery 22 may be charged with electric power generated by a running engine, a generator, or a solar battery panel 28 mounted on the vehicle body 11 . Alternatively, the battery 22 may be charged from an AC power source (so-called outlet) or an EV charging device at a destination. The battery 22 supplies driving power to the electric motor 23 , the electric submersible pump 41 , the float type electric pump 42 and the electric pump 43 .

The electric motor 23 is connected to the rotating shaft of the pump 24 , and rotates the pump 24 by power supply from the battery 22 . Note that the electric motor 23 and the pump 24 may be integrated. The pump 24 pressurizes the fire extinguishing water sucked from the suction pipe 26 and discharges it to the water discharge hose 27 (Fig. 3). The pump 24 can be efficiently arranged in any orientation regardless of the arrangement and orientation of the engine on the vehicle body 11 .

It should be noted that it is desirable to employ a vertical pump as the pump 24 . By adopting the vertical pump, a fluid cyclone separator can be installed directly below the pump 24 for removing pebbles, metal pieces, and the like that may be mixed with the water that has been absorbed. In addition, the pump 24 can be arranged compactly, and its maintainability can be improved. Furthermore, it becomes easier to realize a watertight structure of the pump unit 20 .

The electric motor 23 can be used as a regenerative power generator by causing water from a fire hydrant or the like to flow into the pump 24 and rotating the rotating shaft of the pump 24 by the water pressure in an emergency other than when a fire is extinguished. The generated power can be stored in the battery 22 .

Furthermore, the pump unit 20 comprises a hose accommodation space 25 at the bottom of its housing 29 . The hose housing space 25 has openings on the left and right sides, and the suction pipe 26 and the water discharge hose 27 can be taken out from either the left or right side, and are wound in parallel to the ground surface and laid flat. made to accommodate. As a result, the suction pipe 26 and the water discharge hose 27 can be easily pulled out and extended. It can also be easily accommodated. Although the details will be described later, in the present embodiment, the water discharge hose 27 can be used as a suction pipe. .

_In the fire pump vehicle 101, the fire extinguishing water absorbed by the electric submersible pump 41 attached to the tip of the suction pipe 26 and the float-type electric pump 42 disposed in the middle of the suction pipe 26 and floating on the water surface is absorbed by the pump 24. Water is absorbed through a suction pipe 26, pressurized and discharged to a water discharge hose 27, and water is discharged from a nozzle 44 attached to the tip of the water discharge hose 27. - 特許庁The electric submersible pump 41 and the float-type electric pump 42 may be made to suck water at the same time, or only one of them may be made to suck water depending on the state of mud on the bottom of the water, garbage on the surface of the water, and the like.

When it is necessary to assist or strengthen the water absorption capacity or water discharge pressure of the pump 24 , one or a plurality of electric pumps 43 can relay the suction pipe 26 and the water discharge hose 27 . Further, if necessary, the electric pump 43 can be replaced with a higher performance one, so that the water absorption capacity and the water discharge pressure can be easily enhanced.

According to the fire pump truck 101, the pump unit 20 is detachably _mounted on the ladder frame 13 of the vehicle body 11, so it is possible to procure a non-custom-made general-purpose vehicle and combine the pump unit 20 with it. , it can be manufactured at a lower cost than a conventional firefighting pump car in which a vehicle body and a firefighting pump are integrated. Furthermore, if the pump unit 20 is standardized and standardized, mass production becomes possible, and the production cost can be reduced. Furthermore, when inspecting and repairing the vehicle body 11, the pump unit 20 can be easily loaded and unloaded.

In addition, if the vehicle body 11 has deteriorated while the pump unit 20 is still in a usable state, the pump unit 20 can be reused by replacing only the vehicle body 11. 10 ₁ can be updated inexpensively. Conversely, when the pump unit 20 breaks down, the pump unit 20 can be replaced, so the repair period for the fire pump truck ₁₀₁ can be shortened.

Further, according to the pump unit 20, since the electric submersible pump 41 is used, the vacuum pump which is required in the conventional fire fighting pump becomes unnecessary. This also eliminates the need for an automatic discharge shutoff valve, a water stop valve, and a check valve. In addition, since the suction pipe 26 does not generate negative pressure, the negative pressure performance is not required, so the water discharge hose 27 can be used. Furthermore, the allowable range of the negative pressure performance (watertight performance) of the pump 24 is widened.

If a conventional firefighting pump is used over time, an electric vacuum pump driven by the power of the battery 22 or an electric compressor may be introduced. As a result, by simply switching the air line, in addition to the conventional pump negative pressure (vacuum) test, pressurization (positive pressure) test is possible without using actual water. Both air leak and simple water leak tests can be performed in, for example, a fire station garage without having to move the vehicle to the water source, reducing the cost of routine inspections.

In addition, since the pump unit 20 does not use the power source of the vehicle body 11, the pump driving device that is required in the conventional fire pump is not required. In this way, the pump unit 20 does not require various parts that are required in conventional fire fighting pumps, so maintenance and replacement of these parts are not required, and failure factors can be reduced.

Furthermore, if the suction pipe 26, the water discharge hose 27, the electric submersible pump 41, the float type electric pump 42, the electric pump 43, and the nozzle 44 _mounted on the fire pump vehicle 101 are appropriately combined, Multiple water discharge lines can be assembled. The water discharge line can be used, for example, for drainage work in a flood-stricken area or the like. In addition, the water discharge line can also be used for fire extinguishing work, although the water pressure is lower than in the case of using the pump 24 .

<Fire pump truck 10 ₂ according to the second embodiment of the present invention>
Next, FIG. 4 is a side view showing a configuration example of a fire pump truck 102 according to a _second embodiment of the present invention.

The fire pump truck 10-3 is detachably mounted with a vertical gate unit 50 instead of the pump unit ₂₀ in the fire pump truck _10-2 . The vertical gate unit 50 has a vertical gate 51 that can move up and down while a heavy object is loaded. The bottom of the vertical gate 51 can be lowered to the bottom of the rear wheels (ground) and can be raised to the ceiling of the vertical gate unit 50 . The lowest part of the vertical gate 51 may be lowered further than the lowest part (ground) of the rear wheels (state shown in FIG. 10). Equipment can be accommodated in the empty space of the box-shaped housing of the vertical gate unit 50 .

_The fire pump truck _10-3 has the same actions and functions as those of the fire pump truck 10-1, and also requires human labor when loading and unloading heavy objects (for example, a crawler 60 (FIG. 8) described later). can be reduced.

<Fire pump truck 10 ₃ according to the fourth embodiment of the present invention>
Next, FIG. 6 is a side view showing a configuration example of a fire pump truck 104 according to a _fourth embodiment of the present invention. Among the constituent elements of the fire pump truck 104 _, those that are common to the constituent elements of the fire pump truck 103 (FIG. ₅ ) are denoted by the same reference numerals, and description thereof will be omitted.

The fire pump truck 104 is obtained by changing the two-axle _four -wheel fire fighting pump truck 103 to a _three -axle six-wheel specification. The drive system may be all-wheel drive, full-time drive of the two rear axles and four wheels, or part-time drive of one of the rear two axles and four wheels. Furthermore, a lift axle specification that allows one of the rear two-axle four wheels to be lifted from the ground may be used. Also, double tires may be adopted for the rear two-axle four-wheels.

The fire pump truck ₁₀₄ has the same actions and functions as the fire pump truck 103, and in addition, it has a ₃ -axle 6-wheel specification. can.

<Fire pump truck 10 ₅ according to the fifth embodiment of the present invention>
Next, FIG. 7 is a side view showing a configuration example of a fire pump truck 105 according to a _fifth embodiment of the present invention. Among the constituent elements of the fire pump truck 10 ₅ , those that are common to the constituent elements of the fire pump truck 10 ₄ (FIG. 6) are given the same reference numerals, and the description thereof is omitted.

The fire pump vehicle 105 is a semi-tracked vehicle in which crawlers (tracks) ₆₀ are attached to rear two-axle four-wheels of three-axes and six-wheels. The drive system of the fire pump truck 105 is all _- wheel drive, and the rearmost axle 15 is designed as a lift axle that can float the tires forward and upward from the ground.

However, the crawler ₆₀ is detachable from the fire engine pump truck 105 because the crawler 60 runs on a paved road with high friction and cannot increase its speed. Therefore, it is preferable that the crawler 60 is made of rubber, which is lighter and easier to attach and detach than the crawler made of metal.

8 to 11 show how the crawler 60 is attached to the rear axles 14 and 15 of the three-axle six-wheel.

First, as shown in FIG. 8, on level ground, the unmounted crawler 60 is lashed to the top or inside of the vertical gate unit ₅₀ , and the fire engine pumper 105 is driven to the front of the rough road while the crawler 60 is mounted. . Next, as shown in FIG. 9, the crawler 60 is manually placed on the vertical gate 51, the vertical gate 51 is lowered to the ground, and then the crawler 60 is moved to the ground.

Next, as shown in FIG. 10, by further lowering the vertical gate 51, the tires on the rear axles 14, 15 are lifted. Then, the crawler 60 is mounted on the tires of the axles 14 and 15 with the axle 15 floating forward and upward. At this time, when the tires of the axles 14 and 15 are double tires, as shown in FIG. Lateral displacement of the crawler 60 can be prevented by mounting the crawler 61 so that it is sandwiched between the double tires. Further, when the tires of the axles 14 and 15 are single tires, as shown in FIG. , and mounting so that the two protrusions 62 sandwich the single tire, the lateral displacement of the crawler 60 can be prevented.

Finally, tension is applied to the crawler 60 by returning the axle 15 to its original position, and then the vertical gate 51 is raised to ground the crawler 60 to the ground. In addition, when removing the crawler 60, the procedure described above may be performed in reverse.

If the axle 15 is not a lift axle specification, as shown in FIG. After mounting the crawler 60 with the rollers 63 lowered, tension may be applied to the crawlers 60 by raising the upper supporting rollers 63 .

The fire pump truck _10-5 has the same functions and functions as those of the fire pump truck _10-4 , and also has a rough road running performance that is even higher than that of all-wheel drive. Firefighting and rescue operations can be carried out.

The fire pump truck _10-5 is provided with an outrigger 72 (FIG. 12) similar to the fire pump truck _10-6 , which will be described later. You may make it expand-contract to.

The multifunctional robotic arm 83 has at least the function of moving the stretcher 90 inside the emergency unit 80 . In addition, the multifunctional robot arm 83 may be configured to perform cardiac massage or the like as an aid to emergency treatment for a patient being transported. In addition, it is preferable that the multifunctional robot arm 83 can be operated by a remote controller, a smartphone, or the like.

Furthermore, the emergency unit 80 may be equipped with an air conditioner 84 independent of the vehicle body 11 . Thereby, the temperature/humidity in the room of the emergency unit 80 can be adjusted to the temperature/humidity suitable for transporting the sick or wounded. If the air conditioner 84 integrated with the outdoor unit is detachably mounted on the ceiling of the housing 86, maintenance such as repair can be easily performed. In addition, the mounting port of the air conditioner 84 provided on the ceiling of the housing 86 can be used as an emergency escape port in the event of an accident such as a rollover of the vehicle.

The air conditioner 84 may provide positive/negative pressure capability in the room of the emergency unit 80 . As a result, for example, when a person infected with an infectious disease is transported, the inside of the housing 86 can be negatively pressurized to prevent the spread of viruses and the like. In addition, for example, when being in an area where chemical substances, toxic gases, etc. may exist, the inside of the housing 86 can be positively pressurized to prevent chemical substances, etc. from entering the housing 86 . A positive pressure/negative pressure device may be installed separately from the air conditioner 84 .

Furthermore, the emergency unit 80 may be equipped with a large-capacity battery 85 independent of the vehicle body 11 . The battery 85 is composed of, for example, a lithium ion battery, an all-solid battery, or the like, and is charged in advance before dispatch. However, the battery 85 may be charged with electric power generated by a running engine or generator mounted on the vehicle body 11 or by the solar cell panel 28 . As a result, stable electric power can be supplied to the medical equipment mounted on the emergency unit 80, the air conditioner 84, and the like. Further, the battery 85 may be charged from an AC power source (so-called outlet) or an EV charging device at a hospital or the like to which the patient is transported. As a result, the waiting time at the destination hospital or the like can be utilized.

Additionally, the top of housing 86 of emergency unit 80 may be equipped with emergency vehicle accessories 31 (FIG. 1).

Since the fire pump truck ₁₀₇ has a vibration isolating function for the entire emergency unit 80 by means of a vibration isolating device 81, compared to the vibration isolating function of only a bed in the vehicle provided in a conventional ambulance, it is possible to ride in the vehicle while traveling. It can increase the availability of medical care by emergency responders and doctors, and improve safety.

In addition, since the fire pump truck ₁₀₇ is provided with the vertical gate 82, it is possible to suppress the occurrence of an accident in which the injured person falls from the stretcher 90, which has conventionally occurred when the stretcher 90 was manually accommodated in the vehicle. In addition, the labor burden on ambulance crews can be greatly reduced.

The pump unit ₂₀₂ may be omitted from the fire pump truck ₁₀₇ , and only the emergency unit 80 may be mounted.
