Description

Title of the invention: Removable fire extinguishing device for an emergency vehicle Technical field of the invention

[0001] The invention relates to a fire extinguishing device intended to be removably attached to an emergency vehicle equipped with a water tank. The invention also relates to an emergency vehicle comprising such a fire extinguishing device. The invention further relates to a method of intervention for extinguishing a fire using such an emergency vehicle. Prior art

[0002] To extinguish fires, firefighters have intervention vehicles equipped with a water tank connected to a water hose or water cannon. Water is generally projected at the base of the flames in order to extinguish them.

[0003] The extinguishing technique must nevertheless be adapted according to the type of fire encountered. Among the known types of fires are stubble fires. A stubble fire is a fire that breaks out in a field after harvest, when only the stalks and roots of the plants (called stubble) remain on the ground. These fires can occur accidentally, often due to sparks from agricultural machinery, or as a result of intentional farming practices to clear fields. Stubble fires are generally of moderate intensity compared to forest or building fires. However, stubble fires can spread rapidly, especially in dry and windy conditions, and can eventually reach adjacent forests or buildings. Therefore, stubble fires must be able to be extinguished quickly and effectively. Current firefighting vehicles are generally poorly suited to extinguishing such stubble fires.

[0004] Furthermore, a firefighting vehicle is generally equipped with various specific accessories (winches, protective equipment, lighting, etc.) useful for dealing with diverse and varied situations. These accessories are arranged all around the firefighting vehicle so as to be easily accessible to firefighters responding to a fire. A firefighting vehicle is also a vehicle likely to travel on public roads, sometimes at high speed, to reach the scene of an incident. Consequently, firefighting vehicles must comply with road traffic regulations, in particular EC Directive 2005 / 66 / EC, which stipulates that all accessories mounted on the vehicle and located less than 2 meters from the ground must be pre-installed. approved. Such regulations aim to prevent the attachment of accessories that could prove very dangerous in the event of a collision with a pedestrian. Therefore, attaching a new accessory to an emergency vehicle requires renewing the vehicle's type approval, which is quite a cumbersome process. In practice, an emergency vehicle cannot be easily modified once it is in service. Presentation of the invention

[0005] The object of the invention is to provide a fire extinguishing device and an intervention vehicle equipped with such a fire extinguishing device, remedying the above disadvantages and improving upon the fire extinguishing devices and intervention vehicles known in the prior art.

[0006] More specifically, a first object of the invention is a fire extinguishing device which makes it possible to effectively extinguish a stubble fire and which does not require any new approval of the intervention vehicle. Summary of the invention

[0030] Figure 1 schematically illustrates a firefighting vehicle 1 according to an embodiment of the invention. The firefighting vehicle 1 is adapted for extinguishing fires. In particular, the firefighting vehicle 1 is adapted for extinguishing stubble fires or fires of a nature equivalent to stubble fires. The vehicle 1 mainly comprises a water tank 2 and a firefighting device 3 hydraulically connected to the water tank 2. The firefighting device 3 is removably attached to a support 4 fixed to the vehicle. The firefighting device 3 is designed to project water onto the ground forward and downward. Preferably, the firefighting device 3 is designed to project water over an area whose width is substantially equal to the width of the firefighting vehicle.The fire extinguishing device 3 is intended to be used simultaneously with the intervention vehicle 1 as it advances, in order to progressively extinguish a stubble fire.

[0031] The X-axis is defined as the longitudinal axis of the intervention vehicle 1. When moving forward in a straight line, the intervention vehicle progresses from rear to front in a direction parallel to its longitudinal axis. The X-axis is oriented from the front to the rear of the intervention vehicle, that is, in the direction of reverse. The Y-axis designates the transverse axis of the intervention vehicle. The Y-axis is oriented from left to right, left and right being defined from the perspective of a driver of the intervention vehicle. The Z-axis designates the axis perpendicular to the X-axis and the Y-axis. The intervention vehicle 1 is considered to be resting on a horizontal surface. The Z-axis is a vertical axis, oriented from bottom to top. The X, Y, and Z axes form an orthogonal coordinate system.This same reference point, defined by reference to an emergency vehicle, will also be used to describe the fire extinguishing device 3, even when considered outside the emergency vehicle, since it is intended for mounting in a specific orientation on the emergency vehicle.

[0032] In addition, the intervention vehicle 1 is equipped with a pump 5 adapted to pressurize the water contained in the water tank 2. The fire extinguishing device 3 is hydraulically connected to a water outlet of the pump 5 by a water pipe 9, which is attached to the intervention vehicle 1.

[0033] As shown in [Fig. 1], the intervention vehicle 1 can also be equipped with a water cannon 6, in particular mounted on the roof of the vehicle. The water cannon 6 is intended to project water over a greater distance from the intervention vehicle 1 than the fire extinguishing device 3. The water cannon 6 is also hydraulically connected to the water outlet of the pump 5 by hydraulic lines. In addition, the intervention vehicle 1 also includes a flow control device. The flow control device includes a first valve 71 having a hydraulic inlet connected hydraulically to the pump 5, and a hydraulic outlet connected hydraulically to the fire extinguishing device 3. The flow control device also includes a second valve 72 having a hydraulic inlet connected hydraulically to the pump 5 and a hydraulic outlet connected hydraulically to the water cannon 6.The flow control device can be configured to supply water only to the fire extinguishing device 3, or only to the water cannon 6, or simultaneously to supply water to the fire extinguishing device 3 and the water cannon 6, or to cut off the water supply to both the fire extinguishing device 3 and the water cannon 6. In one embodiment, the intervention vehicle could be without the water cannon 6.

[0034] Figure 2 now illustrates more precisely the bracket 4 on which the fire extinguishing device 3 is fixed. The bracket 4 is advantageously equipment of the emergency vehicle 1 which is not specifically intended for the fixing of the fire extinguishing device 3. The support 4 may in particular be an element of a protection device for an engine of the intervention vehicle 1 such as a stone guard; also called a "protective skid plate".

[0035] The support 4 can be positioned on the lower part of the front of the emergency vehicle, in particular between a horizontal underbody and a vertical face of the emergency vehicle. The support 4 can be positioned below the vehicle's headlights and / or extend between the two front wheels of the vehicle. The support 4 is positioned at a height of 2 meters or less from the ground. Therefore, as required by automotive regulations, any equipment attached to the support 4 must be pre-approved before the vehicle can be driven on a public road.

[0036] The support 4 is not intended to be removed from the emergency vehicle except, of course, for repair or maintenance of the emergency vehicle. In particular, the support 4 may be an engine protection plate for the emergency vehicle 1. The plate is attached, for example by welding, to the body of the emergency vehicle. The plate is advantageously provided with ventilation holes 8 to allow some engine ventilation. The plate, which is preferably a metal plate, has sufficient rigidity to protect the engine from impacts and projectiles. The ventilation holes 8 and / or the rigidity of the plate can advantageously be used to attach the fire extinguishing device 3 in a removable manner.

[0037] The plate extends in a plane oriented forwards and upwards. For example, the plate extends in a plane forming an angle between 20° and 70° inclusive with the vertical axis Z. The fire extinguishing device 3 is intended to project water in a direction at least roughly perpendicular to the plane in which the plate extends, i.e., forwards and downwards towards the intervention vehicle 1. The reaction force associated with the water projection tends to press the fire extinguishing device 3 against the plate.

[0038] Figures 3 and 4 illustrate in more detail the fire extinguishing device 3. The fire extinguishing device 3 comprises a water distribution ramp 11, a plurality of water ejection nozzles 12 distributed along the ramp 11, a hydraulic fitting 13 configured to hydraulically connect the ramp 11 to a pipe leading to the water tank 2, and a fastening means 14 intended to cooperate with the support 4 to fix the fire extinguishing device 3 removably to the support 4.

[0039] The ramp 11 may be a tube, preferably metallic, extending parallel to the transverse axis Y. The ramp may have a length substantially equal to the width of the intervention vehicle, for example, between 50% and 200% of the width of the intervention vehicle along the transverse axis Y. A first end of the ramp 11 can be closed by a plug 15. A second end of the ramp 11 can be hydraulically connected to the hydraulic fitting 13.

[0040] According to the embodiment presented, the fire extinguishing device 3 comprises six nozzles 12 evenly distributed along the boom 11. Alternatively, this number could be different, for example, between three and ten nozzles inclusive. Each nozzle 12 includes an ejection hole whose shape, orientation, and dimensions are adapted to project water forwards and downwards. In particular, each nozzle can be designed to form a flat jet of substantially triangular shape, said jet intersecting the ground along a transversely oriented segment. For this purpose, the ejection hole of each nozzle 12 can have an oblong shape. The water jets produced by the various nozzles 12 thus make it possible to wet an area located in front of the intervention vehicle, for example less than 3 meters from the ramp 11, and extending over the entire width of the intervention vehicle 1. Each nozzle can, for example, be welded or screwed to the ramp 11.Each nozzle can be made of steel or brass, for example.

[0041] The hydraulic fitting 13 allows the boom 11 to be hydraulically and removably connected to the water line 9 leading to the water tank 2 via the first valve 71 and the pump 5. The hydraulic fitting 13 is therefore designed to cooperate with a supplementary hydraulic fitting 16 provided on the water line 9. Advantageously, the hydraulic fitting 13 is self-contained and removable. By "self-contained," it is understood that the hydraulic fitting 13 can be used without any specific tools or equipment. For example, the hydraulic fitting 13 can be a snap-fit ​​or hand-screw connection to the supplementary hydraulic fitting 16. By "removable," it is understood that the hydraulic fitting 13 can be disconnected and reconnected at will from the supplementary hydraulic fitting 16. Advantageously, the hydraulic fitting 13 is connected to the boom 11 via a flexible hose 20 to facilitate the joining of the hydraulic fittings 13 and 16.

[0042] The mounting means 14 is also self-contained and removable. The fire extinguishing device 3 can thus be attached to the bracket 4 without tools and can be easily removed or reattached to the bracket 4. It is therefore understood that the entire fire extinguishing device 3 is configured for simple and quick installation on the emergency vehicle 1. The fire extinguishing device 3 thus provides an effective means of action against stubble fires but does not require any new vehicle type approval since it can be quickly removed as soon as the emergency vehicle needs to travel on a public road. Furthermore, removing the fire extinguishing device 3 prevents it from being damaged by various projectiles. Indeed, its positioning on the lower part of the face The front of the emergency vehicle makes it particularly vulnerable to splashes. Therefore, it is preferable to remove the fire extinguishing device 3 when it is not in use.

[0043] As a note, the fire extinguishing device 3 is positioned in front of the The ventilation holes (8) limit engine ventilation. This is not a problem because the fire suppression system (3) is designed for use when the emergency vehicle is traveling at low speeds, thus reducing engine load. The fire suppression system (3) also provides additional protection for the emergency vehicle, particularly the engine and front wheel area, by cooling the ground in front of the vehicle with a water spray. This additional protection can facilitate the movement of the emergency vehicle through a fire.

[0044] Furthermore, the fire extinguishing device 3 comprises a frame 17 to which the water distribution boom 11 is attached. The boom can, for example, be welded or screwed to the frame 17. According to the embodiment illustrated in [Fig. 4], the boom 11 is attached to the frame 17 by means of U-shaped brackets 18. Two nuts 19 cooperating with the two ends of the bracket 18 allow the boom 11 to be tightened against the frame 17. This method of attaching the boom 11 to the frame 17 is simple to implement and allows for easy adjustment of the direction of the water jets from the boom 11 by rotating the boom 11 around its axis. The angle formed by the water jet with the ground can thus be easily modified. According to the embodiment presented, the ramp 11 is fixed to the chassis 17 by means of three clamps 18. Alternatively, this number could be different, and preferably greater than or equal to two.

[0045] According to the embodiment illustrated in [Fig.3], the fastening means 14 comprises two attachment means 25, 26 fixed to the ramp 11 and spaced apart from each other along the transverse axis Y. Alternatively, the number of attachment means could be different, for example a single attachment means or three attachment means. Each attachment means 25, 26 comprises, on the one hand, a first hook 21 movable in translation relative to the frame 17 and a first return means 22, in particular a first spring, bearing on the frame 17 on the one hand and on the first hook 21 on the other hand. On the other hand, each attachment means comprises a second hook 23 movable in translation relative to the frame 17, and a second return means 24, in particular a second spring, bearing on the frame 17 on the one hand and on the second hook 23 on the other hand. The first hook 21 and the second hook 23 are movable in translation parallel to the same axis. In particular, the axis about which the two hooks are movable is an axis perpendicular to the transverse axis Y and belonging to a plane in which the support 4 extends. The two hooks 21, 23 are thus positioned substantially one above the other. The first hook 21 is a lower hook and the second hook 23 is an upper hook. Both hooks 21 and 23 have retaining teeth facing each other. The two hooks 21 and 23 can be separated by compressing the two return means 22 and 24.

[0046] A method for attaching the fire extinguishing device 3 to the support 4 is illustrated in Figures 5 and 6. First, the fire extinguishing device 3 is brought close to the support 4, inclined at a greater angle than the support 4. Then, the first hook 21 of each attachment means is inserted into a ventilation hole 8. Next, the fire extinguishing device 3 is rotated while an upward pulling force is applied to the ramp 11. This is very easy to perform because the ramp 44 is at eye level and provides an obvious, natural gripping means. By applying an upward pulling force to the ramp 11, the first retrieval means 22 is compressed. Compressing the first retrieval means 22 allows the second hook 23 to pass over an upper edge 27 of the support 4.When the second hook 23 is positioned directly above the upper edge 27 of the support 4, the upward pulling force exerted on the ramp can be released. The second hook 23 then engages with the upper edge 27 of the support 4, and the tension in the two retractors 22, 24 is balanced. This fastening method is extremely quick and can be applied in just a few seconds, which is particularly advantageous for rapid fire response. The fire extinguishing device 3 is designed so that the two retractors 22, 24 remain under tension when it is attached to the support 4. This ensures the secure retention of the fire extinguishing device 3.

[0047] Figures 7, 8, 9, and 10 illustrate various embodiments of the fastening means. These embodiments are described by showing only the differences compared to the first embodiment described above. For simplicity, the same reference numerals will be used to designate elements performing an identical or similar function to the first embodiment, with the suffixes B, C, D, and E respectively for each of these embodiments.

[0048] According to the embodiment shown in [Fig. 7], the fire extinguishing device 3B comprises two hooks 21B, 23B equipped with retaining teeth facing in opposite directions, and not facing each other. According to this embodiment, each hook 21B, 23B is intended to cooperate with a ventilation hole 8 in the support 4.

[0049] Figure 8 illustrates a 3C fire extinguishing device according to yet another embodiment of the invention. This embodiment differs from the embodiment of Figure 7 in that the two return means 22, 24 are replaced. by a single return means 28C, in particular a single spring. The return means 28C comprises a first end bearing on the first hook 21C and a second end bearing on the second hook 23C.

[0050] The embodiment of [Fig.9] differs from the embodiment of [Fig.4] in that the fire extinguishing device 3D comprises a single retraction means 22D cooperating with the first hook 21D. The second hook 23D is fixed to the frame 17D while the first hook 21D slides relative to the frame 17D.

[0051] The embodiment shown in [Fig. 10] illustrates a fire extinguishing device 3E in which the first hook 21E is fixed relative to the frame 17E and the second hook 23E slides relative to the frame 17E. The first hook 21E is intended to cooperate with the upper edge 27 of the support 4, while the second hook 23E is intended to cooperate with a ventilation hole 8 in the support 4. The fire extinguishing device 3E further includes a single return means 28E comprising a first end fixed to the frame 17E and a second end fixed to the second hook 23E. The return means 28E is preferably a spring configured to be subjected to a tensile force. To assemble or disassemble the fire extinguishing device 3E from the support 4, an upward tensile force must be applied to the second hook 23E.This alternative embodiment has the advantage of being simple to manufacture and offering a particularly robust and reliable attachment to support 4.

[0052] According to the embodiment shown in [Fig. 11], the fastening means comprises a magnetic element 29F for use with the support 4. In this case, the support 4 is necessarily a ferromagnetic element. The magnetic element 29F can be, for example, a magnetized plate for attachment to the support 4. Advantageously, a filter membrane, for example made of plastic, can be provided to prevent the transmission of filtration from the emergency vehicle to the fire suppression device 3E and vice versa. Such a fastening means is particularly quick to implement and provides a robust attachment. Advantageously, the ramp 11 provides a significant lever arm for easily detaching the magnetic element 29F from the support when the fire suppression device needs to be removed.

[0053] To use the fire extinguishing device 3 described above, the following procedure can be followed. First, in a preliminary phase, the emergency vehicle is driven to the site of a stubble fire. For this purpose, the fire extinguishing device 3 is detached from its support 4 and stored in the cargo compartment of the emergency vehicle 1. The emergency vehicle 1 can then travel safely on a public road. Next, once it has arrived at the scene of a To extinguish a stubble fire, the fire suppression system is installed. This is done by attaching the system to the support in a removable manner and connecting the hydraulic fitting to a line leading to the water tank, as previously explained. This operation can be carried out very quickly and without tools. The pump 5 can then be activated, and if necessary, the first valve 71 can be opened to supply water to the boom 11. Finally, the stubble fire is extinguished by projecting water forward and downward with the fire suppression system 3 while moving relatively slowly with the vehicle, for example, at a speed of 7 km / h or less.

[0054] By way of example, the water pressure in the boom 11 can be on the order of ten bars, for example between 5 and 15 bars. The water flow rate through the fire suppression system 3 can be on the order of 150 L / min, for example between 100 L / min and 300 L / min. In addition, the fire monitor 6 can also be used to project water over a greater distance from the fire engine 1.
