Description

Technical Field

[0001] This utility model relates to fire extinguishing equipment, and more particularly to a fire extinguishing robot and fire extinguishing system. Background Technology

[0002] Vehicles are generally transported by roll-on / roll-off (Ro-Ro) ships, which are widely used due to their high loading and unloading efficiency. Therefore, their fire prevention management and firefighting rescue measures are particularly important. In the event of a fire, the traditional rescue method involves the captain organizing a skilled crew to conduct fire reconnaissance, identify the fire source, the direction of fire spread, and the trend of fire development, formulate a feasible firefighting plan, and organize firefighting efforts. Especially in situations with heavy smoke, firefighters must ventilate the area, then use water spray guns as cover to gradually approach the fire source, cover the burning fuel tank with foam, cool the fuel tanks of other vehicles with direct water jets, and simultaneously spray open flames on the vehicle body and cargo. If the fuel tank has already exploded and the oil fire has spread, it is necessary to cover a large area of ​​the deck with foam to extinguish the oil fire, and then use water guns to extinguish the fire on the cargo carried by the vehicle. In this firefighting method, firefighters are directly exposed to the confined fire environment of the vehicle, affecting their safety. This is especially true for new energy vehicles, where thermal runaway fires spread extremely quickly, making firefighting difficult and posing a greater threat to the lives of firefighters. There are technical solutions that provide fire-fighting robots that can move on steep walls to extinguish fires; however, their capacity to carry extinguishing agents is low, resulting in low fire-fighting efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fire-fighting robot that is suitable for use on roll-on / roll-off ships and improves fire-fighting capabilities.

[0052] Please refer to Figures 1-4 This application provides a fire-fighting robot, including a first robot body 100 and a fire-fighting device 200.

[0053] The first robot body 100 includes a frame 110, an adsorption assembly 120, and a first moving assembly 130. The adsorption assembly 120 and the first moving assembly 130 are disposed on the frame 110. The adsorption assembly 120 is used to adsorb onto the top of the cabin, and the first moving assembly 130 is configured to move the first robot body 100 when the adsorption assembly 120 is adsorbed onto the top of the cabin. This allows the first robot body 100 to move on the top of the cabin, thereby enabling it to move above the vehicle.

[0054] The fire extinguishing device 200 is installed on the first robot body 100 and can move with the first robot body 100 to the top of the vehicle and spray fire extinguishing agent toward the vehicle to extinguish the fire.

[0055] Please refer to Figures 1-8 This application also provides a fire extinguishing system, including a fire extinguishing robot, a side-positioning fire extinguishing robot, and a lifting fire extinguishing robot 20.

[0056] Among them, the fire-fighting robot is used to move from the top of the cabin to above the vehicle and spray fire extinguishing agent on the top of the vehicle. The side-positioning fire-fighting robot 10 is used to move to the side of the vehicle and spray fire extinguishing agent on the side of the vehicle. The lifting fire-fighting robot 20 is used to move to the bottom of the vehicle and puncture the vehicle's battery to spray battery fire extinguishing agent onto the battery.

[0057] Understandably, in actual firefighting scenarios, one or more of the above three types of firefighting robots can be deployed as needed. Specifically, the number of firefighting robots, side-positioning firefighting robots 10, and lifting firefighting robots 20 can be one or more. When there are multiple firefighting robots, side-positioning firefighting robots 10, and lifting firefighting robots 20, one or more can be deployed simultaneously to perform firefighting operations, such as multiple side-positioning firefighting robots 10 operating simultaneously.

[0058] The three types of firefighting robots mentioned above enable multiple firefighting robots to work together to extinguish fires from multiple different angles when new energy vehicles catch fire, thereby improving firefighting capabilities.

[0059] Please refer to Figure 1 and Figure 2 In some embodiments, the first moving component 130 includes a motor 131, a reducer, a transmission component 132, and a drive wheel 133. The transmission component 132 includes a driving wheel 1321 and a driven wheel 1322. The diameter of the driving wheel 1321 is smaller than the diameter of the driven wheel 1322. The motor 131 outputs power, and the power output by the motor 131 is transmitted sequentially through the reducer, the driving wheel 1321, and the driven wheel 1322 to the drive wheel 133, thereby enabling the drive wheel 133 to move on the top of the cabin. The drive wheel 133 can be a wheel structure or a track structure.

[0060] Understandably, motor 131 is connected to the reducer, the reducer is connected to the drive wheel 1321, the drive wheel 1321 is connected to the driven wheel 1322, and the driven wheel 1322 is connected to the drive wheel 133. The reducer can increase the output torque, and since the diameter of the drive wheel 1321 is smaller than the diameter of the driven wheel 1322, the output torque can be further increased. A harmonic reducer can be selected as the reducer.

[0061] In the above embodiment, the adsorption component 120 adheres to the top of the cabin, enabling the fire-fighting robot to overcome its own weight and remain on the top of the cabin. The drive wheel 133 abuts against the top of the cabin, and the motor 131 outputs power. The power is transmitted sequentially through the reducer, the drive wheel 1321, and the driven wheel 1322 to the drive wheel 133, causing the drive wheel 133 to move on the top of the cabin. By setting a reducer and making the diameter of the drive wheel 1321 smaller than the diameter of the driven wheel 1322, the output torque can be increased to overcome the suction force of the adsorption component 120, and the weight of the carried fire-fighting device 200 can also be increased to improve the fire-fighting capability.

[0062] In some embodiments, the first robot body 100 further includes a second moving component 140, the second moving component 140 and the first moving component 130 being arranged sequentially along the front-back direction of the first robot body 100, and the adsorption component 120 being disposed between the second moving component 140 and the first moving component 130.

[0063] It is understood that the adsorption components 120 are distributed relatively in the middle of the vehicle's length direction, thereby improving the adsorption stability between the adsorption components 120 and the top of the cabin. In some embodiments, the adsorption components 120 are magnetic components, and specifically, electromagnet components can be selected.

[0064] When the adsorption component 120 adsorbs onto the top of the cabin, the center of gravity of the first robot body 100 and the fire extinguishing equipment as a whole is projected along the direction of gravity within the projection of the adsorption component 120, thus maintaining the stability of the adsorption. The first robot body 100 also includes a battery pack 170, which partially overlaps with the adsorption component 120 along the height direction of the first robot body 100, thereby improving the adsorption stability.

[0065] To achieve the steering function, in some embodiments, the number of the first moving components 130 is two, that is, two sets of motors 131, reducers, transmission components 132, and drive wheels 133 are each provided. Among them, the two sets of drive wheels 133 are coaxially arranged, and the two sets of motors 131 are configured to achieve steering by making the corresponding drive wheels 133 rotate at different speeds.

[0066] Furthermore, in some embodiments, two sets of motors 131 are arranged sequentially along the front-rear direction of the first robot body 100, wherein one set of driving wheels 1321 and one set of driven wheels 1322 are located on one side of the width direction of the first robot body 100, and the other set of driving wheels 1321 and the other set of driven wheels 1322 are located on the other side of the width direction of the first robot body 100. It is understood that the two sets of motors 131 are oriented in opposite directions.

[0067] In this configuration, the two sets of driven wheels 1322 are coaxially arranged with their corresponding drive wheels 133. In some specific embodiments, both the drive wheel 1321 and the driven wheel 1322 are sprockets, and the two are connected by a chain 1323.

[0068] Two sets of motors 131 are positioned above the adsorption component 120. The projections of the two sets of motors 131 on the reference plane coincide with the projection of the adsorption component 120, which makes the center of gravity more stable. The reference plane is a horizontal plane.

[0069] The motor 131 and the reducer are integrated into one unit, forming a harmonic integrated machine. There is a gap between the battery pack 170 and the adsorption component 120, and two sets of harmonic integrated machines are arranged in the gap. The battery pack 170, the harmonic integrated machines, and the adsorption component 120 are arranged along the height direction of the first robot body 100.

[0070] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the second moving component 140 includes at least one set of rotatable support wheels, which together with the drive wheel 133 abut against the top of the cabin. The support wheels can be provided as one set or multiple sets can be arranged coaxially.

[0071] The support wheel assembly includes a wheel body 141 and multiple rings 142. The wheel body 141 has a hub 1411, and the rings 142 are fitted onto the hub 1411. The axis of the rings 142 is perpendicular to the axis of the wheel body 141. The rings 142 are capable of rotating around the hub 1411.

[0072] It is understandable that the suction force of the adsorption component 120 results in a large steering resistance. By fitting a ring 142 onto the hub 1411 of the wheel body 141, the ring 142 can rotate around the hub 1411 during steering, thereby changing the sliding friction into rolling friction and significantly reducing steering resistance.

[0073] Furthermore, in some embodiments, the wheel body 141 includes a plurality of support spokes 1412, which support the hub 1411, and each support spoke 1412 is connected to the hub 1411. A ring 142 is provided between any two adjacent support spokes 1412. This confines each ring 142 between two support spokes 1412, thereby limiting the sliding of the ring 142 along the hub 1411.

[0074] The wheel body 141 can be integrally formed. A reinforcing part 1413 is provided at the connection position between the support spokes 1412 and the hub 1411. The reinforcing part 1413 protrudes outward from the hub 1411, and its radial height along the wheel body 141 is lower than that of the ring body 142. Several annular grooves are formed on the outer circumferential surface of the ring body 142, and the center of each annular groove is located on the axis of the ring body 142.

[0075] In some embodiments, the frame 110 includes a first frame 111 and a second frame 112 spaced apart along the width direction of the first robot body 100. The first frame 111 is connected to the second frame 112 and defines a mounting cavity. The battery pack 170 is disposed within the mounting cavity, and the harmonic drive unit is also disposed within the mounting cavity, located below the battery pack 170. The drive wheel 133 and the support wheel assembly are rotatably mounted on the frame 110 and distributed on both sides of the harmonic drive unit along the front-rear direction of the first robot body 100. The first frame 111 and the second frame 112 are provided with mounting holes for the harmonic drive unit and the drive wheel 133. The support wheel assembly is mounted to the first frame 111 and the second frame 112 via support seats.

[0076] One set of driving wheels 1321 and one set of driven wheels 1322 are disposed on the first frame 111 and located on the side away from the mounting cavity, while another set of driving wheels 1321 and another set of driven wheels 1322 are disposed on the second frame 112 and located on the side away from the mounting cavity.

[0077] Please refer to Figure 1 and Figure 4 In some embodiments, the first robot body 100 further includes at least one mounting base 150 and multiple clamping members 160. The mounting base 150 is disposed on the frame, and the number of fire extinguishing devices 200 is the same as that of the mounting base 150, that is, each fire extinguishing device 200 is disposed on one mounting base 150.

[0078] Each fire extinguishing device 200 is mounted on the mounting base 150 via a clamp 160. Each fire extinguishing device 200 has a first nozzle 210. The mounting base 150 is configured to adjust the orientation of the first nozzle 210 by adjusting the position of the fire extinguishing device 200.

[0079] The main body of the fire extinguishing device 200 is a cylindrical structure, and the mounting base 150 has an arc groove that fits the main body. The fire extinguishing device 200 can rotate around its own center line, thereby adjusting the orientation of the first nozzle 210.

[0080] It is understandable that when multiple fire extinguishing devices 200 are installed and arranged side by side, if the fire extinguishing device 200 is first installed on the mounting base 150 and then the clamping member 160 is installed, the adjacent fire extinguisher will affect the clamping action of the clamping member 160.

[0081] In some embodiments, the mounting base 150 includes a first base 151 and a second base 152. The first base 151 is connected to the vehicle frame, and the second base 152 is connected to the fire extinguishing device 200 via a clamp 160. It also includes a detachable hinge that allows the second base 152 to be detachably connected to the first base 151. This allows the second base 152 to be first connected to the fire extinguishing device 200 via the clamp 160, and then installed onto the first base 151.

[0082] In other embodiments, the mounting base 150 includes a first base 151 and a second base 152. The first base 151 is connected to the frame 110, and the second base 152 is connected to the fire extinguishing device 200 via a clamp 160. The first base 151 has two hinge positions, one of which is provided with a movable hinge member. The movable hinge member can move to a first position or a second position. When the hinge member is in the first position, the second base 152 can rotate around the other hinge position. When the hinge member is in the second position, the second base 152 is connected to the first base 151 via the two hinge positions.

[0083] Please refer to Figure 5 and Figure 6 In some embodiments, the side-mounted fire extinguishing robot 10 includes a second robot body 101, a telescopic arm 102, a second nozzle 103, and a lifting assembly 104.

[0084] The second robot body 101 has a moving function. A telescopic arm 102 is disposed on the second robot body 101, and the telescopic arm 102 includes multiple arm segments 1021 connected in sequence. A second nozzle 103 is used to spray fire extinguishing agent. The second nozzle 103 is disposed on the telescopic arm 102 and is configured to move away from the second robot body 101 when the telescopic arm 102 is extended, or to move closer to the second robot body 101 when the telescopic arm 102 is retracted. A lifting assembly 104 is disposed on the second robot body 101 and is used to support the telescopic arm 102 and adjust the angle of the telescopic arm 102 relative to a reference plane. The telescopic arm 102 has a working state and a retracted state. In the working state, the extended telescopic arm 102 forms a preset angle with the reference plane so that the second nozzle 103 is aimed at the vehicle window.

[0085] In the above embodiment, the second robot body 101 moves to the side of the vehicle, drives the telescopic arm 102 to swing relative to the reference plane to a preset angle through the lifting component 104, and extends the telescopic arm 102 so that the telescopic arm 102 enters the working state. At this time, the second nozzle 103 is aimed at the vehicle window to spray fire extinguishing agent onto the vehicle, thereby realizing automatic fire extinguishing and avoiding people being in a relatively confined vehicle fire environment.

[0086] In the retracted state, all segments 1021 of the telescopic arm 102 are positioned on the same reference plane to improve throughput; this reference plane is horizontal. Of two adjacent segments 1021, one has a slide rail arranged along the telescopic direction, and the other slides on the slide rail, thus enabling relative movement between adjacent segments 1021 along the telescopic direction. For the telescopic drive of each segment 1021, in some embodiments, each segment 1021 is equipped with a rack, which meshes with a gear. The gear is connected to a telescopic drive component, which drives the gear to rotate, thereby driving the telescopic extension and retraction of each segment 1021.

[0087] The lifting assembly 104 includes a lifting drive assembly, a fixed base 1041, and a folding arm 1042. The lifting drive assembly can be a motor or a cylinder. One end of the telescopic arm 102 is hinged to the fixed base 1041, forming a first hinge position 1041a. The folding arm 1042 is hinged to the telescopic arm 102 and the fixed base 1041. The lifting drive assembly drives the folding arm 1042 to unfold, so that the telescopic arm 102 rotates around the first hinge position 1041a until it forms a preset angle relative to the reference plane, or drives the folding arm 1042 to fold, so that the telescopic arm 102 is at the reference plane. The arrangement of the lifting drive assembly is not limited. In some embodiments, one end of the lifting drive assembly is hinged to the fixed base 1041, and the other end is hinged to the part of the telescopic arm 102 that connects to the folding arm 1042, thereby achieving folding through telescopic extension.

[0088] Please refer to Figure 7 and Figure 8 In some embodiments, the lifting fire extinguishing robot 20 includes a third robot body 201, a lifting device 202, a lifting demolition head 203, and a third nozzle 204. The lifting device 202 is disposed on the third robot body 201, and the lifting demolition head 203 and the third nozzle 204 are disposed on the lifting device 202. The lifting device 202 is configured to drive the lifting demolition head 203 and the third nozzle 204 to rise and fall relative to the third robot body 201. The lifting demolition head 203 is configured to cut the outer armor of the vehicle battery under the drive of the lifting device 202, and the third nozzle 204 is configured to inject battery fire extinguishing agent into the cut location of the vehicle battery's outer armor.

[0089] In the above embodiment, when the vehicle battery catches fire, the lifting fire extinguishing robot 20 can move to the bottom of the vehicle battery. The lifting device 202 drives the lifting demolition head 203 and the third nozzle 204 to rise relative to the third robot body 201 to approach the vehicle battery until the lifting demolition head 203 cuts the outer armor of the vehicle battery. The third nozzle 204 can inject battery fire extinguishing agent into the cut position of the outer armor of the vehicle battery, thereby extinguishing the fire.

[0090] The lifting device 202 includes a lifting seat 2021 that can be raised and lowered relative to the third robot body 201. The top surface of the lifting seat 2021 is used to support the vehicle battery. The lifting and breaching head 203 is mounted on the lifting seat 2021 and protrudes upward from the lifting seat 2021. Understandably, during the lifting and armor-piercing process, the lifting and breaching head 203 contacts and cuts the outer armor of the vehicle battery until the top surface of the lifting seat 2021 supports the vehicle battery, at which point the lifting stroke ends. In other words, the height of the lifting and breaching head 203 protruding upward from the lifting seat 2021 limits the cutting depth of the lifting and breaching head 203.

[0091] The lifting device 202 includes a base 2022, a first articulated arm assembly 2023, a second articulated arm assembly 2024, and a lifting drive assembly 2025.

[0092] The lifting seat 2021 is positioned above the base 2022, with the two spaced apart. The first hinge arm assembly 2023 and the second hinge arm assembly 2024 are hinged together and positioned between the lifting seat 2021 and the base 2022. A hinge point is formed at the middle of the first hinge arm assembly 2023 and the second hinge arm assembly 2024. It is understood that when the first hinge arm assembly 2023 and the second hinge arm assembly 2024 rotate around this middle hinge point, their heights will change.

[0093] The lifting drive assembly 2025 is configured to drive one end of the first articulated arm assembly 2023 toward one end of the second articulated arm assembly 2024 to move the lifting seat 2021 away from the base 2022, or drive one end of the first articulated arm assembly 2023 away from one end of the second articulated arm assembly 2024 to move the lifting seat 2021 toward the base 2022.

[0094] When the distance between one end of the first articulated arm assembly 2023 and one end of the second articulated arm assembly 2024 is at its maximum, the distance between the lifting seat 2021 and the base 2022 is at its minimum, meaning the lifting fire-fighting robot 20 is at its lowest height, has the best passability, and can move to the bottom of the vehicle battery. When the third robot body 201 reaches the predetermined position, the lifting drive assembly 2025 is activated, and the distance between one end of the first articulated arm assembly 2023 and one end of the second articulated arm assembly 2024 gradually decreases, causing the lifting seat 2021 to gradually move away from the base 2022, increasing the height of the lifting fire-fighting robot 20 until the lifting operation is complete. The lifting drive assembly 2025 includes a lead screw assembly, whose lead screw nut is connected to one end of the first articulated arm assembly 2023, thereby driving it away from or towards one end of the second articulated arm assembly 2024.
