Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a suspended transport fire extinguishing robot. Background Technology

[0002] In industrial production, automobile repair, and equipment maintenance scenarios, there is often a need for firefighting in low, narrow spaces (such as under a car chassis, gaps between large equipment bases, and pipe interlayers). The spatial characteristics of such scenarios are: the height is usually less than 0.8 meters, the lateral width is limited, and there may be complex environmental conditions such as equipment components obstructing the view and oil stains adhering to the surface, which bring significant technical bottlenecks to traditional firefighting methods. From the perspective of personnel operation, the traditional manual handheld fire extinguisher method has core limitations: On the one hand, it is difficult to accommodate personnel in narrow spaces, and operators need to bend over, turn sideways, or even crawl to work, which not only consumes a lot of physical strength, but may also cause deformation of operation due to spatial compression, making it impossible to accurately control the direction of the fire extinguisher nozzle; on the other hand, some scenarios (such as fire extinguishing under a car chassis) may have high-temperature components and leakage risks, and close-range operation by personnel can easily cause safety accidents such as burns and electric shocks, further limiting the feasibility of manual fire extinguishing. From the perspective of fire extinguishing medium delivery, conventional fixed sprinkler equipment (such as workshop sprinkler systems and wall-mounted fire extinguishing devices) is also difficult to adapt to the needs of such scenarios: First, the installation position and spray angle of fixed sprinklers are usually preset and cannot be flexibly adjusted according to the dynamic position of the fire source in a narrow space (such as the ignition point of different parts of a car chassis). This results in the fire extinguishing medium (such as water and dry powder) being easily blocked by equipment components and unable to reach the core area of ​​the fire source, resulting in the problem of "not being able to spray or cover completely". Second, the spray range of conventional sprinklers is mostly large-area coverage, which can easily lead to the waste of fire extinguishing medium in narrow spaces, and some precision equipment may be damaged by excessive media immersion. Third, for scenarios such as car chassis that require mobile fire extinguishing, fixed sprinklers cannot move with the position of the fire source, making it difficult to achieve continuous and precise fire extinguishing operations. In addition, while existing mobile fire extinguishing equipment (such as small fire extinguishing carts) has a certain degree of mobility, its nozzle height and spray angle adjustment range are limited due to its size design, and it still cannot reach into low and narrow spaces. Furthermore, some equipment relies on its own water storage tank for water supply, which has insufficient endurance. If a continuous fire occurs, the fire extinguishing may be interrupted due to the depletion of water supply, further highlighting the technical shortcomings of traditional fire extinguishing methods in narrow space applications. Utility Model Content

[0003] In view of this, this utility model provides a suspended transport fire extinguishing robot to solve the problems of traditional fire extinguishing methods, such as personnel being unable to approach narrow spaces and the difficulty in accurately delivering fire extinguishing media to the target fire source.

[0008] Furthermore, the drive unit includes a driven wheel connected to the rotating shaft and an electric cylinder disposed in the mounting bracket, wherein the piston rod end of the electric cylinder is provided with a rack; the driven wheel is connected to the rack in a driving connection.

[0009] Furthermore, the mounting bracket is also provided with a detachable guide block; the guide block is provided with a guide groove for accommodating the rack.

[0010] Furthermore, one end of the carrier is provided with a second connection part for connecting to an external water source. The external water source can be connected to the water pipe through the second connection part and supply water to the water pipe.

[0011] Furthermore, the top of the carrier is provided with a cover plate for covering the carrier, and the cover plate is provided with water outlet holes corresponding to a plurality of the nozzles.

[0012] Furthermore, it also includes a second set of drive wheels disposed between the first set of drive wheels; both the first set of drive wheels and the second set of drive wheels are independently driven; the second set of drive wheels includes a first drive unit and a second drive unit with the same structure as the first drive unit.

[0013] Furthermore, the first drive unit includes a rotating shaft and a rotating frame that can rotate based on the rotating shaft; both ends of the rotating frame are provided with rotatable auxiliary wheels; the rotating frame is fixedly mounted on the rotating shaft in a "∽" shape.

[0014] The suspended transport fire extinguishing robot provided by this utility model has the following beneficial effects: In this invention, the water pipes distributed along the support rods on the top of the carrier frame and the corresponding spray holes, combined with the adjustable movement trajectory via a controller, allow the extinguishing medium to be precisely aimed at the target fire source in a narrow space.

It completely solves the pain point of traditional fire extinguishing methods where the extinguishing medium cannot accurately reach the fire source, greatly improving fire extinguishing efficiency and effectiveness, ensuring that the fire source is quickly controlled, and reducing property damage.

Unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all within the protection scope of the present invention. Example

[0018] Please see Figure 1 This utility model provides a suspended transport fire extinguishing robot. Fires frequently occur in low-lying, confined spaces, such as underground garages, machine shops, and electrical equipment compartments. Examples include fires caused by oil leaks from car chassis, short circuits in machine tool wiring, and smoldering fires in gaps under electrical cabinets. These fires often occur in enclosed spaces with narrow passages, and may be surrounded by obstacles such as parts and cables, posing multiple challenges to traditional fire extinguishing methods. From a personnel safety perspective, when using a handheld fire extinguisher to deal with such fires, operators must squeeze into confined spaces. This not only restricts physical movement and makes it difficult to quickly adjust extinguishing posture, but also increases the risk of breathing difficulties and obstructed vision due to dense smoke, high temperatures, or toxic gases, thus increasing the risk of suffocation and burns. If the fire involves electrical equipment, close-range operation may also pose a risk of electric shock, further threatening life. Even with protective equipment, operational flexibility in confined spaces is significantly reduced, leading to slow extinguishing actions and missed opportunities to extinguish the fire.

[0019] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a flat-panel, suspended transport fire extinguishing robot is provided. The fire extinguishing robot includes a frame 100 for mounting a controller 120 and a power supply 130, and a first set of drive wheels 210 disposed at both ends of the frame 100 for driving the frame 100. The first set of drive wheels 210 is powered by the power supply 130 and driven by the controller 120, so that the frame 100 moves towards the target area. A water pipe is provided inside the top of the frame 100. The water pipe is distributed along the support rod 110 provided at the top of the frame 100. The water pipe is provided with a plurality of nozzles at intervals. The support rod 110 at the top of the frame 100 is provided with water spray holes 111 corresponding to the nozzles.

[0020] Upon detecting a fire in a low-lying, confined space, such as under a car chassis or machine tool, the controller 120 activates the first set of drive wheels 210, powered by the power supply 130, which propels the carrier 100 towards the target fire-fighting area. This method eliminates the need for manual pushing of the equipment, avoiding the safety risks of high temperatures, dense smoke, and electrical leakage faced by personnel approaching the fire area, thus solving the problem of personnel injury during traditional manual handling of fire-fighting equipment. Furthermore, the drive-wheel-driven carrier 100 can flexibly navigate narrow passages or obstacles, allowing it to get closer to the fire source compared to traditional mobile fire-fighting carts that are limited in size, laying the foundation for precise fire suppression.

[0021] After the carrier 100 arrives at the target area, water is delivered from an external source to several nozzles spaced apart on the water pipes distributed along the support rod 110 inside the top of the carrier 100. The extinguishing medium is sprayed through the nozzles and directed towards the fire source through the corresponding water spray holes 111 on the support rod 110. This method, through the distribution of water pipes along the support rod 110 and the correspondence between the nozzles and water spray holes 111, allows the extinguishing medium to be precisely aimed at the fire source in a low, narrow space, avoiding the blind spots caused by the fixed spray direction of traditional fixed nozzles and their susceptibility to obstruction by components. At the same time, the spaced nozzles can achieve uniform coverage of the fire source, avoiding both media waste or damage to surrounding precision components due to excessive pressure from a single point of spray, and insufficient pressure that fails to cover the fire source. This solves the pain points of inaccurate media delivery and uneven coverage in traditional fire extinguishing methods.

[0022] During firefighting, the controller 120 can adjust the direction of movement of the first set of drive wheels 210 in real time, driving the carrier 100 to move slowly, so that the nozzles on the water pipe and the spray holes 111 on the support rod 110 are continuously aligned with the dynamically changing fire source, while maintaining a stable supply of the medium in the water pipe. This method relies on the mobility of the carrier 100 and the continuous liquid supply of the water pipe. Compared with traditional handheld fire extinguishers, which require frequent position adjustments and have limited liquid storage, this method can achieve longer and more flexible continuous firefighting. Moreover, the load-bearing structure of the carrier 100 can stably support the water pipe and drive system, avoiding nozzle deviation caused by equipment shaking during firefighting, further ensuring that the extinguishing medium always acts accurately on the fire source, and improving firefighting efficiency and effectiveness.

[0023] Furthermore, to ensure that the power supply 130 and controller 120 are protected from water damage during firefighting operations, a waterproof system can be constructed from both the structural and component protection aspects of the carrier 100. In the area of ​​the carrier 100 used to install the power supply 130 and controller 120, a sealed cavity design is adopted. A water-resistant sealing ring is installed at the connection between the cavity sidewall and the cover plate 150. Simultaneously, an inclined guide channel is provided at the bottom of the cavity to prevent water splashes from accumulating inside the cavity during firefighting. The outer casing of the power supply 130 and controller 120 is made of flame-retardant and waterproof material, and waterproof plugs are used at the interfaces to prevent water pipes or moisture from the external environment from seeping into the internal circuitry. In addition, a reinforced waterproof pad can be added to the cover plate 150 at the location corresponding to the installation area of ​​the power supply 130 and controller 120 to further block water droplets that may splash from the spray nozzles 111, ensuring a continuous and stable power supply to the power supply 130 and precise control of the drive wheel and fire extinguishing medium delivery by the controller 120. This prevents equipment failure due to water damage and ensures continuous firefighting operations.

[0024] Further, please see Figure 1 , Figure 5 and Figure 6Both ends of the carrier 100 are equipped with robotic arms 300, which can be expanded or retracted based on the carrier 100 under the control of the controller 120.

[0025] Furthermore, the robotic arm 300 includes a first connecting portion 310 and an extension portion 320 that can rotate based on the first connecting portion 310; the robotic arm 300 also includes a drive portion 340 that is disposed at the bottom of the extension portion 320 via a mounting bracket 330 and is capable of driving the extension portion 320 to rotate.

[0026] Furthermore, the first connecting part 310 is provided with a hinge seat 311 for accommodating the extension part 320 and a receiving groove 312 provided on the hinge seat 311. The rotating shaft 341 of the driving part 340 passes through the receiving groove 312 and is connected to the hinge seat 311. The rotating shaft 341 is provided with a bearing 342, and the extension part 320 can rotate within a preset angle range based on the rotating shaft 341 through the bearing 342.

[0027] Furthermore, the drive unit 340 includes a driven wheel 343 connected to the rotating shaft 341, and an electric cylinder 344 disposed in the mounting bracket 330. The piston rod end of the electric cylinder 344 is provided with a rack 345; the driven wheel 343 is connected to the rack 345 in a transmission connection.

[0028] Furthermore, the mounting bracket 330 is also provided with a detachable guide block 346; the guide block 346 is provided with a guide groove 347 for accommodating the rack 345.

[0029] Specifically, in scenarios such as auto repair shops, flammable and explosive sites, urban roads, or logistics warehouses, the robotic arm 300, relying on the carrier 100, enables flexible movement and transfer of vehicles. The specific usage revolves around three steps: state switching, angle adjustment, and precise docking. The entire process is controlled by the controller 120, without the need for direct human intervention. When vehicle relocation is required, the controller 120 first sends an extension command to the robotic arm 300: the electric cylinder 344 in the drive unit 340 is activated, and its piston rod pushes the rack 345 at its end to move stably along the guide groove 347 of the guide block 346 on the mounting bracket 330. The rack 345 and the driven wheel 343 form a transmission engagement, driving the rotating shaft 341 connected to the driven wheel 343 to rotate; the rotating shaft 341 passes through the receiving groove 312 on the hinge seat 311 of the first connecting part 310 and connects with the extension part 320. The bearing 342 is connected, and when the shaft 341 rotates, it will drive the extension part 320 to gradually unfold from the retracted state around the shaft 341 with the bearing 342 as the fulcrum. At this time, the robotic arms 300 at both ends of the carrier 100 move synchronously. After the extension part 320 is unfolded, it can expand the overall bearing area of ​​the carrier 100, which is convenient for subsequent docking with the bottom of the vehicle or the load-bearing part. For example, when transferring commercial vehicles in logistics warehousing, the unfolded robotic arms 300 can provide stable support from both sides of the vehicle to prevent the vehicle from shifting during movement. When dealing with vehicles of different heights and parking angles (such as large vehicles parked at an angle in a repair shop or vehicles with their wheels stuck due to illegal parking), and the angle of the extension section 320 needs to be adjusted to meet the receiving requirements, the controller 120 will precisely control the extension and retraction of the electric cylinder 344 according to a preset program or external command: the distance that the electric cylinder 344 pushes the rack 345 to move is different, and the rotation angle of the driven wheel 343 driving the rotating shaft 341 is also different, which in turn drives the extension section 320 to adjust to the corresponding angle through the bearing 342; for example, for large vehicles with high chassis, the extension section 320 will rotate upward to raise the receiving part, ensuring that the receiving part can accurately fit the bottom of the vehicle; for remote vehicle relocation scenarios in flammable and explosive places, docking can be completed remotely by adjusting the angle of the extension section 320 through the controller 120 without the need for personnel to approach, which ensures safety and avoids the precision error of manual adjustment.

[0030] When the operation is completed, such as when the vehicle is transferred to the target location or the illegal vehicle is towed to the designated area, the controller 120 sends a retraction command to the robotic arm 300. The electric cylinder 344 drives the rack 345 to move in the opposite direction, the driven wheel 343 rotates in the opposite direction to the rotating shaft 341, and the extension part 320 retracts around the rotating shaft 341 to the initial retracted state, reducing the space occupied by the robotic arm 300, facilitating the movement of the carrier 100 in narrow passages, and preparing for the next operation or equipment storage. Further, please see Figure 1 One end of the carrier 100 is also provided with a second connection part 140 for connecting to an external water source. The external water source can be connected to the water pipe through the second connection part 140 and supply water to the water pipe.

[0031] Further, please see Figure 1The top of the carrier 100 is also provided with a cover plate 150 for covering the carrier 100, and the cover plate 150 is provided with water outlet holes 151 corresponding to a plurality of the nozzles.

[0032] When the device detects a fire in scenarios such as auto repair shops or flammable and explosive locations, the firefighting operation proceeds step by step, focusing on water supply access, medium delivery, and precise fire suppression, and is coordinated with the mobility of the carrier 100 throughout the process.

[0033] First, the staff connects to an external water source (such as a fire hose or workshop water supply pipe) through the second connection 140 at one end of the carrier 100. The external water flows quickly into the pre-installed water pipe inside the top of the carrier 100 through the second connection 140. Compared to relying on the device's own water storage, this design can achieve a continuous supply of extinguishing medium, avoiding interruption of fire fighting due to insufficient water storage. Subsequently, the controller 120 activates the first set of drive wheels 210, moving the carrier 100 to a location directly below or close to the fire source. During this process, the cover plate 150 on the top of the carrier 100 protects the internal water pipes, controller 120, and other components from the high-temperature radiation and sparks from the fire source, reducing the risk of equipment damage. Once the carrier 100 reaches the target position, the extinguishing medium in the water pipe is delivered along the distribution path of the support rod 110 to several nozzles spaced at intervals. The nozzles pressurize the medium and spray it. At this time, the water outlet holes 151 on the cover plate 150, which correspond one-to-one with the nozzles, play a guiding role, allowing the extinguishing medium to accurately pass through the water outlet holes 151 and directly act on the low-lying fire source (such as flames in the gaps of the vehicle chassis or the ignition point of ground accumulation). The position of the water outlet holes 151 is strictly aligned with the nozzles, which can prevent the extinguishing medium from being deflected due to the cover plate 150 during the spraying process, and at the same time prevent the medium from splashing onto surrounding unrelated equipment, reducing secondary losses. If the fire has a tendency to spread, the controller 120 can adjust the moving direction of the carrier 100 in real time, driving the water pipe and nozzles to move synchronously, so that the water outlet holes 151 are continuously aligned with the dynamic fire source, realizing fire extinguishing while moving, and further improving the fire extinguishing coverage and efficiency.

[0034] Further, please see Figure 2 and Figure 4 The carrier 100 also includes a second set of drive wheels 220 disposed between the first set of drive wheels 210; the first set of drive wheels 210 and the second set of drive wheels 220 are both driven independently; the second set of drive wheels 220 includes a first drive part 221 and a second drive part 225 with the same structure as the first drive part 221.

[0035] Furthermore, the first drive unit 221 includes a rotating shaft 223 and a rotating frame 222 that can rotate based on the rotating shaft 223; both ends of the rotating frame 222 are provided with rotating auxiliary wheels 224; the rotating frame 222 is fixedly mounted on the rotating shaft 223 in a "∽" shape.

[0036] Specifically, the second set of drive wheels 220 serves as an auxiliary power unit for the movement of the carrier 100, working in conjunction with the first set of drive wheels 210. Its usage can be flexibly switched according to road conditions, focusing on standby in normal road conditions, activation in complex road conditions, and dynamic adaptation. In normal scenarios such as flat roads, the second set of drive wheels 220 is in standby mode, and the carrier 100 moves normally solely relying on the first set of drive wheels 210. At this time, the controller 120 only supplies power to the first set of drive wheels 210, and the first drive section 221 and the second drive section 225 of the second set of drive wheels 220 are not activated. The "∽"-shaped rotating frame 222 maintains its initial position, and the auxiliary wheels 224 do not contact the ground, avoiding additional power consumption and ensuring the economy and flexibility of the carrier 100's movement on flat roads. When the carrier 100 travels to a section of road with a large slope or with potholes or grooves, the staff can start the second set of drive wheels 220 through the controller 120. When the first set of drive wheels 210 works alone, it has problems such as insufficient power, weak climbing ability and easy getting stuck in potholes. At this time, the second drive unit 225 drives the rotating shaft 223 to rotate, causing the "∽"-shaped rotating frame 222 to flip downwards. The auxiliary wheels 224 at both ends then contact the ground, forming a four-point support drive structure together with the first set of drive wheels 210, and using its independent drive characteristics to form a linkage with the first set of drive wheels 210; the first drive unit 221 and the second drive unit 225 work synchronously, driving their respective rotating shafts 223 to rotate, thereby driving the "∽"-shaped rotating frame 222 fixed on the rotating shaft 223 to rotate. Because the rotating frame 222 has a "∽" shaped structure, and the maximum height of the auxiliary wheels 224 exceeds the height of the first set of drive wheels 210 when rotating, the auxiliary wheels 224 on both sides will alternately contact the ground when the rotating frame 222 rotates. In the case of a ramp, the auxiliary wheels 224 can penetrate into the gaps or protrusions on the ramp surface, enhancing the grip of the frame 100 on the ground and preventing the first set of drive wheels 210 from slipping. In the case of potholes, when the first set of drive wheels 210 is stuck in a pothole or suspended in the air, the rotating auxiliary wheels 224 can support the bottom of the frame 100 by relying on the higher contact height, and at the same time, the forward force generated by the rotation will drive the frame 100 to cross the pothole area. In addition, the pair of moving wheels of the second set of drive wheels 220 are symmetrically distributed under the frame 100, and always maintain synchronous speed when rotating, ensuring that the frame 100 will not tilt due to unilateral power imbalance when moving in complex road conditions. During the process of the carrier 100 traversing complex road conditions, the controller 120 can adjust the rotation speed of the second set of drive wheels 220 and the rotation angle of the rotating frame 222 according to the real-time road conditions. For example, when facing a steep slope, the rotation speed of the rotating shaft 223 is increased, so that the auxiliary wheels 224 can alternately contact the ground more quickly, thereby increasing the driving force. When facing a deep groove, the angle of the rotating frame 222 is finely adjusted so that the auxiliary wheels 224 can embed into the edge of the groove with a better contact posture, thereby enhancing the lifting effect, until the carrier 100 completely leaves the complex road conditions. At this time, the second set of drive wheels 220 can be turned off, and the normal movement mode of the first set of drive wheels 210 driving alone can be restored. Furthermore, the design of the second set of drive wheels 220 provides crucial support for the movement of the carrier 100 from three dimensions: traffic stability, scenario adaptability, and operational safety, making up for the shortcomings of relying solely on the first set of drive wheels 210. Firstly, it improves traffic stability in complex road conditions, solving the problems of slippage and jamming; compared to the traditional single set of drive wheels which are prone to slippage on slopes and jamming on potholes, the second set of drive wheels... Furthermore, the design of the second set of drive wheels 220 provides crucial support for the movement of the carrier 100 from three dimensions: traffic stability, scenario adaptability, and operational safety, making up for the shortcomings of relying solely on the first set of drive wheels 210. Firstly, it improves traffic stability in complex road conditions, solving the problems of slippage and jamming. Compared to the traditional single-set drive wheels which are prone to slippage on slopes and jamming in potholes, the combination of the "∽"-shaped rotating frame 222 and auxiliary wheel 224 of the second set of drive wheels 220 can dynamically adapt to road undulations through rotation, and its independent drive characteristics allow the two sets of drive wheels to distribute power according to road conditions. For example, when driving on a slope, the first set of drive wheels 210 provides the main forward propulsion, while the second set of drive wheels 220 enhances stability through the grip of the auxiliary wheel 224, preventing the carrier 100 from slipping backward. When driving in potholes, the second set of drive wheels 220 provides additional lifting and driving force to prevent the carrier 100 from getting stuck in the pothole, ensuring that firefighting and transport operations are not interrupted due to road conditions. In scenarios such as unpaved roads outside auto repair shops, potholed roads in old urban residential areas, and ramps in logistics and warehousing areas, the carrier 100 relying solely on the first set of drive wheels 210 is insufficient for passage. However, the addition of the second set of drive wheels 220 allows the device to flexibly cope with these complex road conditions. For example, when towing illegally parked vehicles in urban management, if the vehicle is parked in a pothole on the side of the road, the device can smoothly approach the vehicle using the second set of drive wheels 220. When extinguishing fires in flammable and explosive locations, if there are ramps or collapses on the road surface around the fire, the device can also reach the fire area with the help of the second set of drive wheels 220, breaking the limitation that it can only operate on flat roads.

[0037] The second set of drive wheels 220 has a pair of symmetrically arranged moving wheels, which maintains balance during rotation. This prevents the carrier 100 from tilting when moving in complex road conditions, preventing the transported vehicles or goods from falling and being damaged. It also prevents the device from tipping over during firefighting, which could lead to water supply interruption or nozzle displacement. At the same time, it eliminates the need for manual pushing of the device across complex road conditions, reducing contact between personnel and dangerous areas and further improving operational safety.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
