Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a fire extinguishing robot. Background Technology

[0002] A fire is a catastrophic combustion phenomenon that is out of control in time or space. Among various disasters, fire is one of the most frequent and widespread major threats to public safety and social development. The losses caused by fires are also increasing year by year, especially in special environments with high temperatures, toxic substances, and explosiveness, where fire suppression is particularly difficult.

[0003] Chinese patent document CN110888442A discloses a fire-fighting robot, relating to the technical field of fire-fighting equipment. It includes a mobile platform equipped with a second camera device, a first camera device, a fire-extinguishing device, and a local controller. The first camera device is a panoramic camera device, and the second camera device is a one-way camera device. The local controller contains a control system that identifies and locates the fire source from the images captured by the second and first cameras. Based on the determined location information, the system controls the movement of the mobile platform and the fire-extinguishing device, and also controls the fire-extinguishing device to perform fire-fighting operations. This fire-fighting robot can automatically identify and locate fire sources from all directions and automatically control the fire-extinguishing device to aim at and extinguish the fire.

[0004] However, the aforementioned firefighting robots also have the following shortcomings: In high-temperature fire environments in the wild, the robot chassis is exposed to high-temperature radiation and heat waves. If it is not cooled down in time, the chassis components (such as wheel system or tracks) will be easily deformed, damaged or malfunctioned, affecting the robot's mobility and continuous operation capability, thus making it unable to adapt to long-term, high-intensity field rescue scenarios.

[0040] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] Example:

[0042] The present invention will now be further described with reference to the accompanying drawings.

[0043] like Figures 1 to 3 As shown in the figure, this embodiment provides a fire-fighting robot, comprising:

[0044] A mobile chassis 10 is provided, and a lifting seat 11 is installed on the mobile chassis 10. The lifting seat 11 is capable of lifting relative to the mobile chassis 10.

[0045] Attitude adjustment device 12, which is mounted on lifting seat 11;

[0046] Fire extinguishing device 13 is installed on attitude adjustment device 12 and is used to spray fire extinguishing medium toward the fire source.

[0047] Cooling protection device 14 is installed on the mobile chassis 10 and is used to cool and protect the mobile chassis 10.

[0048] The working principle and beneficial effects of the above technical solution are as follows:

[0049] This utility model discloses a fire-fighting robot. The mobile chassis 10 can traverse complex terrain in the wild to approach the fire source and achieve mobile, precise fire extinguishing. With the cooperation of the lifting seat 11 and the attitude adjustment device 12, the attitude of the fire extinguishing device 13 is adjusted to accurately aim at the fire source, and the fire extinguishing device 13 sprays extinguishing media onto the fire source. A cooling protection device 14 is used to cool and protect the mobile chassis 10 during the fire extinguishing process. This utility model provides a fire-fighting robot that, by adding a cooling protection device 14 to the mobile chassis 10, sprays cooling mist onto the bottom of the chassis during the fire extinguishing process, preventing damage to the robot from prolonged exposure to high temperatures. Specifically, cooling the chassis through the cooling protection device 14 reduces damage to electrical components within the chassis, protects the wheel assembly, and compensates for the fire extinguishing blind spots that the fire extinguishing device 13 cannot cover near the robot's body, improving the equipment's durability and continuous operation capability in high-temperature environments.

[0050] Of course, in other embodiments of this application, the cooling protection device 14 includes a cooling fan assembly and a heat sink assembly. The cooling fan assembly is installed at the bottom of the mobile chassis 10 and includes multiple axial fans that generate airflow through a built-in motor. The heat sink assembly is fixed to critical heat-sensitive areas of the mobile chassis 10 (such as near axles or electronic components), and is made of aluminum alloy or copper material with a multi-layer fin structure to enhance heat convection and radiative heat dissipation. In high-temperature environments, the cooling fan assembly of the cooling protection device 14 starts, and the cooling fan assembly drives multiple axial fans through a built-in motor to generate a strong airflow, which is directed downwards from the mobile chassis 10. This airflow not only accelerates the heat convection and radiative heat dissipation of the heat sink assembly, but also disperses potential fire sources or heat waves below the mobile chassis 10, preventing fire sources from approaching or accumulating at the bottom of the chassis, thereby reducing the chassis temperature and preventing chassis components (such as axles or electronic components) from deforming, being damaged, or malfunctioning due to high-temperature radiation. This embodiment achieves active cooling protection by using wind power to disperse the fire source, which is particularly suitable for dry or water-scarce outdoor scenarios, further enhancing the robot's mobility and continuous operation capability in complex fire environments.

[0051] like Figures 4 to 6 As shown, in one embodiment, the cooling protection device 14 includes:

[0052] The lower mounting base 17 is installed at the bottom of the mobile chassis 10;

[0053] Nozzle assembly 18, multiple nozzle assemblies 18 are distributed on the lower mounting base 17.

[0054] The working principle and beneficial effects of the above technical solution are as follows:

[0055] The nozzle assembly 18 is distributed on the lower mounting base 17 and is used to spray atomized water or other cooling media to cool and protect the mobile chassis 10 during fire extinguishing.

[0056] It is worth noting that in some other embodiments, each nozzle assembly 18 is independently fixed to the bottom of the mobile chassis 10.

[0057] In one embodiment, the cooling protection device 14 further includes:

[0058] Adjustment component 19, which is installed in the lower mounting base 17, includes:

[0059] Adjustment chamber 20, which is located within the lower mounting base 17;

[0060] Turntable 21 is located inside regulating chamber 20;

[0061] Drive spurs 22, an equal number of drive spurs 22 to nozzle assembly 18, are distributed in a circular array on turntable 21;

[0062] A drive crossbar 23 is slidably connected at one end to a drive inclined groove 22, and a connecting rod 29 is slidably installed at the other end of the drive crossbar 23. The connecting rod 29 is connected to the nozzle assembly 18 and is used to adjust the extension and retraction of the nozzle assembly 18, so as to realize the extension (for cooling) and retraction (for non-operation protection) of the nozzle assembly 18.

[0063] The working principle and beneficial effects of the above technical solution are as follows:

[0064] The turntable 21 located in the adjustment chamber 20 rotates, which drives the drive bar 23 to move laterally through the drive sloping groove 22. The drive bar 23 achieves the extension and retraction adjustment of the nozzle assembly 18 by flipping.

[0065] In another embodiment of this scheme, the adjustment component 19 can use a gear transmission mechanism instead of a turntable drive. A drive motor 30 is installed in the adjustment chamber 20. The output end of the drive motor 30 is connected to a main gear, which meshes with multiple driven gears. Each driven gear is connected to the connecting rod 29 through a linkage mechanism. When the drive motor 30 rotates, it drives the connecting rod 29 to move linearly through gear transmission, thereby achieving the retraction and extension adjustment of the nozzle assembly 18 in a contraction manner. This design is suitable for space-constrained environments and improves adjustment accuracy and durability.

[0066] In one embodiment, the nozzle assembly 18 includes:

[0067] Storage compartment 24 is located at the bottom end of the lower mounting base 17;

[0068] The flip-up base 25 is installed in the storage chamber 24 via the connecting shaft 26;

[0069] A flipping rod 27 is mounted on a flipping base 25. An atomizing nozzle 28 is mounted on the end of the flipping rod 27 away from the flipping base 25. The flipping base 25 rotates on a connecting shaft 26 to flip the atomizing nozzle 28 into or out of the storage chamber 24.

[0070] The working principle and beneficial effects of the above technical solution are as follows:

[0071] In actual operation, the robot can integrate a fire source identification system (such as the camera device and controller in the prior art). The mobile chassis 10 carries the fire extinguishing medium through complex terrain, and the gimbal 15 controls the fire extinguishing device 13 to accurately extinguish the fire. At the same time, the cooling protection device 14 is activated, the drive motor 30 drives the turntable 21 to rotate, and pushes the connecting rod 29 through the drive sloping groove 22 and the drive crossbar 23. The flipping seat 25 connected to the connecting rod 29 rotates in the storage chamber 24 around the connecting shaft 26, thereby driving the atomizing nozzle 28 installed on the flipping seat 25 through the flipping rod 27 to perform a flipping action, such as... Figure 5As shown, the nozzle assembly 18 is flipped open, and the atomizing nozzle 28 sprays cooling medium to cool the bottom of the chassis, preventing damage from high temperatures. After operation, the nozzle can be folded into the storage chamber 24, improving the durability of the equipment. The flipping lever 27 has a telescopic function, which can increase the spray range of the nozzle assembly 18 when extended.

[0072] In another embodiment of this scheme, the nozzle assembly 18 can adopt a sliding structure instead of a flip-type structure. A sliding track is provided in the storage chamber 24, and the atomizing nozzle 28 is mounted on a sliding seat. The sliding seat slides along the track via a connecting shaft 26. The connecting rod 29 is connected to the sliding seat. When the adjusting component 19 is driven, the sliding seat drives the atomizing nozzle 28 to slide out or into the storage chamber 24 along the track, realizing the unfolding and storage of the atomizing nozzle 28.

[0073] In one embodiment, a drive motor 30 is installed inside the regulating chamber 20, and a turntable 21 is installed at the output end of the drive motor 30.

[0074] In one embodiment, the lower mounting base 17 is rotatably connected to the mobile chassis 10.

[0075] The beneficial effects of the above technical solution are as follows:

[0076] The lower mounting base 17 can rotate actively, thereby increasing the spray range of the nozzle assembly 18.

[0077] In one embodiment, the mobile chassis 10 adopts a six-wheeled chassis.

[0078] The working principle and beneficial effects of the above technical solution are as follows:

[0079] The mobile chassis 10 adopts a six-legged biomimetic design, which can traverse complex terrain in the wild and withstand the counter-thrust of the fire extinguishing device 13.

[0080] In other embodiments of this application, the mobile chassis 10 may also be a wheeled chassis or a tracked chassis, whichever is appropriate depending on the terrain, geology, and energy consumption.

[0081] In one embodiment, the attitude adjustment device 12 includes:

[0082] The gimbal 15 is mounted on the top of the lifting base 11;

[0083] The fire extinguishing device 13 is detachably mounted on the actuating end of the pan-tilt unit 15 via the mounting bracket 16.

[0084] The working principle and beneficial effects of the above technical solution are as follows:

[0085] The gimbal 15 supports multi-axis rotation, enabling the attitude adjustment of the fire extinguishing device mounted on the fixed frame 16, thereby achieving precise aiming at the fire source.

[0086] In one embodiment, the fire extinguishing device 13 is a high-pressure water gun.

[0087] The working principle and beneficial effects of the above technical solution are as follows:

[0088] The fire extinguishing device 13 is a high-pressure water gun, used to spray high-pressure water jets at the fire source, and is suitable for solid fires.

[0089] In other embodiments of this application, the fire extinguishing device 13 may also be a fire extinguishing projectile launcher (launching dry powder or gas fire extinguishing projectiles and remotely throwing them to the fire source), a foam sprayer, or a dry powder sprayer.

[0090] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
