Technical Field
[0001] This utility model relates to the technical field of vehicle-mounted electromagnetic remote fire-fighting equipment, specifically to a vehicle-mounted electromagnetic propulsion remote fire extinguishing device. Background Technology
[0002] In forest, hazardous chemical, fuel, and traffic accident fire scenes, the large size of the fire, the frequent occurrence of secondary explosions, and complex geographical conditions make it difficult for rescue equipment and personnel to quickly approach, or even be able to get close to the scene to carry out rescue operations. This makes it impossible to suppress the fire and conduct timely and effective fire rescue. Long-distance throwing of fire extinguishing bombs is an effective means to solve the above problems. Traditional methods of throwing fire extinguishing bombs include air-propelled, air-dropped, artillery-fired, and rocket-propelled methods. However, these methods are either short-range, lack mobility, have poor throwing accuracy, or are subject to restrictions on the management of pyrotechnic materials. They are also costly to launch and cannot be widely used, making it difficult to achieve economical and efficient fire extinguishing effects.
[0003] Electromagnetic launch technology has unparalleled advantages such as high exit velocity, adjustability, high kinetic energy, and controllable energy, enabling fire extinguishing bombs to be launched without gunpowder, achieving long-distance delivery, and reducing the secondary hazards that may be caused by gunpowder-propelled methods such as artillery and rocket-propelled launches. At the same time, vehicle-mounted deployment enables rapid arrival, maximizes on-site fire extinguishing efficiency, and further improves the safety of on-site rescue personnel. However, existing fire trucks not only cannot provide sufficient electrical power for electromagnetic launch, but also cannot withstand the huge recoil generated during electromagnetic launch, thus failing to meet the requirements of electromagnetic launch of fire extinguishing bombs.
[0004] Therefore, developing and designing a vehicle-mounted electromagnetic propulsion long-range fire extinguishing device that can stably withstand the recoil of electromagnetically launched fire extinguishing projectiles, provide sufficient electrical energy for electromagnetic launch, and enable rapid mobility and precise long-distance delivery is an urgent problem to be solved at present.

[0033] Please refer to Figures 1-4 This invention provides an embodiment of a vehicle-mounted electromagnetic propulsion remote fire extinguishing device, comprising a vehicle body 1, a chassis 11, and several legs 2 distributed along the outer edge of the chassis 11. Each leg 2 includes a horizontal telescopic section and a vertical telescopic section. The horizontal telescopic section includes a nested outer slide cylinder 21 and an inner slide cylinder 22. The outer slide cylinder 21 is fixed to the chassis 11, and the inner slide cylinder 22 is connected to a first drive assembly 23 that drives it to move relative to the outer slide cylinder 21.

The ball joint 25 is connected to a second drive assembly 26 that drives it to move vertically. The second drive assembly 26 is fixed to the inner slide cylinder 22. The horizontal telescopic section allows adjustment of the foot 24 in the horizontal direction. The position of the outriggers 24 can be adjusted to ensure that the terrain directly beneath them is suitable for support. Through the vertical telescopic part and the ball joint 25, the outriggers 24 can automatically sense the ground and adjust their level, so that the outriggers 2 can stably contact the ground and thus firmly support the chassis 11. This effectively withstands the recoil of the electromagnetic launch of the fire extinguishing projectiles while achieving level calibration during the launch process. The electromagnetic launch assembly 3, the pulse power supply 4, and the generator 5 are all located on the chassis 11. The pulse power supply 4 is connected to the electromagnetic launch assembly 3 and can provide short pulses and high-power current to the electromagnetic launch assembly 3. The generator 5 is connected to both the pulse power supply 4 and the electromagnetic launch assembly 3. The electrical energy generated by the generator 5 can directly power the pulse power supply 4 and the electromagnetic launch assembly 3, ensuring that the fire extinguishing projectiles can be launched electromagnetically, enabling rapid mobility and accurate long-distance delivery.
[0034] It should be noted that, in conjunction with UAV detection, this utility model can achieve tracking and aiming of the electromagnetic launch component 3, thereby realizing the precise throwing of the fire extinguishing bomb; furthermore, the vehicle-mounted method achieves the goal of rapid arrival, maximizing the fire extinguishing efficiency on site, and further improving the safety of on-site rescue personnel.
[0035] In this embodiment, please refer to Figure 1 and Figure 4The electromagnetic launch assembly 3 includes a horizontal swivel base 31, a mounting frame 32, a launch elevation frame 33, and an electromagnetic coil launcher 34. The horizontal swivel base 31 is fixed on the chassis 11.

By rotating the mounting frame 32 and the launch elevation frame 33, the electromagnetic coil launcher 34 can be rotated horizontally and tilted vertically, respectively, adjusting the launch attitude of the electromagnetic coil launcher 34, thereby accurately delivering fire extinguishing projectiles.
[0036] It should be noted that the mounting frame 32 and the horizontal swivel base 31 are preferably rotatably connected by a deep groove ball bearing, and a third drive assembly for driving the mounting frame 32 to rotate is provided between the mounting frame 32 and the horizontal swivel base 31; the launch pitch mount 33 and the mounting frame 32 are preferably rotatably connected by a bearing, and a fourth drive assembly for driving the launch pitch mount 33 to rotate is provided between the launch pitch mount 33 and the mounting frame 32; specifically, both the third drive assembly and the fourth drive assembly are preferably servo motors.
[0037] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The rear of the chassis 11 is provided with a flange seat 12, and the horizontal slewing seat 31 is fixed on the flange seat 12; correspondingly, the pulse power supply 4 should be installed in the middle of the chassis 11, and the generator 5 should be installed at the front of the chassis 11.
[0038] Furthermore, the pulse power supply 4 preferably includes a high-voltage pulse charging system, a high-voltage pulse capacitor bank, and a control system. All three parts preferably adopt a modular design and a unified enclosure structure for easy installation and maintenance. The generator 5 is preferably a diesel generator with an external casing. The casing is designed to be dustproof and rainproof, and is soundproof and isolated. The bottom of the casing is treated with shock absorption. The chassis 11 is preferably a special vehicle chassis 11 for fire fighting.
[0039] In this embodiment, please refer to Figure 1 and Figure 3 The cross-sections of both the outer slide cylinder 21 and the inner slide cylinder 22 are preferably square, and the axes of both the outer slide cylinder 21 and the inner slide cylinder 22 are horizontally arranged, which can ensure that the inner slide cylinder 22 can only move in the horizontal direction relative to the outer slide cylinder 21 and will not rotate; furthermore, part of the inner slide cylinder 22 is always located outside the outer slide cylinder 21, which facilitates fixed connection with the second drive assembly 26 and will not interfere with the movement of the inner slide cylinder 22.
[0040] For further details, please refer to Figure 1The outriggers 2 are preferably four in number, with the four outriggers 2 located at the front and rear of the chassis 11 on both sides, respectively, which can provide stable and uniform support for the chassis 11 and reduce tire pressure. In other embodiments, the number of outriggers 2 can also be other values, as long as they can stably withstand the recoil force when the electromagnetic fire extinguishing projectile is launched.
[0041] For further details, please refer to... Figure 1 Straight ladders 13 are provided on both sides of the middle part of the chassis 11, which can facilitate the maintenance of the electromagnetic emission component 3, pulse power supply 4 and generator 5.

[0043] The specific usage of this utility model is as follows:
[0044] This utility model achieves motorized transportation through the vehicle body 1 and gets close to the fire scene;
[0045] After the inner slide cylinder 22 of the horizontal telescopic part of several legs 2 extends horizontally to a suitable distance, the bottom foot 24 of the vertical telescopic part extends vertically downward to the ground, which can automatically adjust the chassis 11 to be horizontal.
[0046] Generator 5 provides low-voltage power to pulse power supply 4. The control system controls the high-voltage pulse charging system to charge the high-voltage pulse capacitor bank according to preset requirements, converting low-voltage power into high-voltage power. The high-voltage pulse capacitor bank is a pulse shaping network composed of multiple pulse capacitor units connected in parallel. It sets the timing, amplitude and pulse width of the multi-stage coils in the electromagnetic launch component 3, and applies high voltage and short pulse current to the corresponding coils. The current flowing through the coil generates a pulsed strong magnetic field. The pulsed strong magnetic field induces a current in the fire extinguishing bomb. The two currents repel each other because they are in opposite directions, and the fire extinguishing bomb is accelerated by the repulsive force. After the continuous force of the fire extinguishing bomb by the coils at each stage, the required exit velocity is finally obtained, and the fire extinguishing bomb is launched.
[0047] It should be noted that the electromagnetic launching component 3 can be installed inside the automatically opening and closing container at the top. When launching the fire extinguishing bomb, the top of the container opens and closes after the launch is completed, which can effectively protect the electromagnetic launching component 3.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
