Description

Technical Field

[0001] This utility model relates to the field of intelligent robot technology, and in particular to a fire-fighting robot. Background Technology

[0002] A firefighting robot is a special type of robot that can replace firefighters in firefighting and rescue missions at dangerous or complex fire scenes. It typically consists of a mobile platform, control unit, self-protection device, and onboard equipment, and possesses manual remote control, semi-autonomous, or autonomous control capabilities to perform specific tasks such as firefighting.

[0003] A search revealed Chinese Patent Publication No. CN208641611U, which discloses a fire-fighting robot, comprising: a fire-fighting robot body; and a support device disposed on the fire-fighting robot body to support the body and balance the forces exerted on it when spraying water. Compared with existing technologies, the fire-fighting robot provided by this invention can effectively eliminate the effect of the robot shifting backward due to the forces exerted on it when spraying water, allowing the robot to more accurately position itself at the target location, thus better performing tasks such as data collection and fire extinguishing.

[0004] Although the aforementioned patents have been approved, they effectively eliminate the effect of the robot shifting backward due to the force applied during water spraying, allowing the robot to more accurately position itself at the target location and better complete tasks such as data collection and water spraying for fire extinguishing. However, when connecting to water pipes, they often rely on complex methods such as bolt tightening or buckle locking. These methods are not only cumbersome to operate, requiring firefighters to spend a lot of time manually connecting and disconnecting, but also make it impossible to quickly maintain and service the robot. Therefore, a fire-fighting robot is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fire-fighting robot, which aims to improve the problem that some existing devices cannot quickly fix and disassemble the connected water pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A firefighting robot includes a mobile platform, a spraying mechanism on the top of the mobile platform, a connecting pipe fixedly connected to the top of the mobile platform, a disassembly mechanism on the top of the connecting pipe, a connecting pipe fixedly connected to the top of the disassembly mechanism, and a blocking component on the outer side of the mobile platform.

[0008] The disassembly mechanism includes a locking ring, which is slidably connected to the top of the connecting tube. Support blocks are fixedly connected to both sides of the outer surface of the locking ring. A rotating rod is rotatably connected to the bottom of the support block. A rotating column is rotatably connected to the adjacent side of the rotating rod. A convex wheel is fixedly connected to the outside of the rotating column. A prying plate is fixedly connected to the outside of the convex wheel. A support block is fixedly connected to the top of the connecting tube. A sliding frame is slidably connected to the top of the support block. A reset assembly is fixedly connected to the bottom of the sliding frame. A connecting assembly is slidably connected to the top of the locking ring.

[0009] The above technical solution, through the design of the locking ring and support block, allows for a firm press at the connection between the connecting pipe and the coupling pipe, ensuring a stable connection. When further securing the connecting pipe is required, the operator operates the lever plate, causing the convex wheel to rotate and align with the bottom of the support block, pulling the support block to enhance the sealing effect. Simultaneously, the sliding frame limits the lever plate, achieving a secure fixation of the connecting pipe. This design effectively prevents loosening or leakage caused by water pressure or external forces, ensuring a stable delivery of extinguishing agents and improving the reliability and extinguishing efficiency of the fire-fighting robot.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes a guide post, the top of which is fixedly connected to the bottom of the sliding frame, a reset spring is sleeved on the outside of the guide post, and the top of the guide post is fixedly connected to the top of the support block.

[0012] The above technical solution provides a stable guide path for the sliding frame by fixing the top of the guide post to the bottom of the sliding frame and fixing the other end to the top of the support block. The return spring sleeved on the outside of the guide post can store energy through its elastic deformation when the sliding frame moves under the action of external force. Once the external force disappears, the return spring releases its elastic force and pushes the sliding frame to automatically slide back to the initial position along the guide post, ensuring the stable reset of the prying plate.

[0013] As a further description of the above technical solution:

[0014] The connecting assembly includes two connecting posts, the outer surfaces of which are slidably connected to the inside of the engaging ring, and the tops of the two connecting posts are fixedly connected to a sliding plate.

[0015] The above technical solution achieves synchronous control and fixation of the locking ring through the sliding connection of two connecting columns inside the locking ring and the sliding plate fixedly connected to the top of the connecting columns.

[0016] As a further description of the above technical solution:

[0017] The spraying mechanism includes two telescopic rods, the bottoms of which are fixedly connected to the top of the moving platform, and the output ends of which are fixedly connected to support plates.

[0018] The above technical solution involves fixing the bottom of two telescopic rods to the top of the moving platform, and using telescopic movement to move the support plate up and down.

[0019] As a further description of the above technical solution:

[0020] An adjustable nozzle is fixedly connected to the top of the support plate, and an adjusting rod is fixedly connected to the top of the moving platform, that is, the outer side near the two telescopic rods.

[0021] Through the above technical solution: the adjustable nozzle fixedly connected to the top of the support plate can be flexibly adjusted according to the height and position of the fire source, and the spray angle and intensity can be changed by rotation or extension to achieve precise fire extinguishing. At the same time, the adjusting rod can have good sliding ability.

[0022] As a further description of the above technical solution:

[0023] The output end of the adjusting rod is fixedly connected to a self-spraying nozzle, and the outside of the adjusting rod is between the connecting pipe and the adjusting nozzle.

[0024] The above technical solution allows for the adjustment of the spray nozzles via an adjusting rod, enabling the mobile platform to spray and cool itself.

[0025] As a further description of the above technical solution:

[0026] The blocking assembly includes two slide rods, which are fixedly connected to the outside of the moving platform, i.e., the outside side near the connecting tube, and a support plate is slidably connected to the outside of the two slide rods.

[0027] The above technical solution involves fixing two slide rods on the outer side of the moving platform near the connecting pipe, providing stable sliding guidance for the support plate. The support plate is slidably connected to the slide rods and can slide along the slide rods.

[0028] As a further description of the above technical solution:

[0029] A limiting plate is fixedly connected to the bottom of the support plate, and a plurality of connecting columns are fixedly connected to the top of the limiting plate. Each of the plurality of connecting columns is fitted with a buffer spring, and a friction block is fixedly connected to the bottom of the plurality of connecting columns.

[0030] Through the above technical solution: the limiting plate fixedly connected to the bottom of the support plate provides stable support for the connecting column, ensuring that the connecting column can maintain vertical movement and will not deviate when subjected to impact. The buffer springs sleeved on the outside of multiple connecting columns can undergo elastic deformation when subjected to impact, absorbing and buffering the external impact energy, effectively reducing the impact force on the mobile platform, protecting the mobile platform and its internal equipment. The friction block fixedly connected to the bottom of the connecting column contacts the ground to generate friction, preventing the mobile platform from sliding or moving backward during water spraying or travel, thus enhancing the stability and safety of the fire-fighting robot.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the locking ring uses the support block to press the connection between the connecting pipe and the connecting tube, keeping the connecting pipe stably connected. The operator moves the lever plate to drive the convex wheel to rotate. The convex wheel fits against the bottom of the support block, pulling the support block to enhance the sealing effect. After the lever plate reaches the designated position, the sliding frame limits it, realizing the firm fixation of the connecting pipe, which enables the connecting pipe to be quickly connected and disassembled.

[0033] 2. In this utility model, when the mobile platform is subjected to the impact force of water spray, the support plate is pressed and slides inward, the buffer spring on the connecting column is compressed, and the impact energy is absorbed through elastic deformation to reduce the impact on the mobile platform. At the same time, the limiting plate provides stable support for the connecting column to prevent it from shifting. Also, during spraying, the support can drive the connecting column to support the ground and prevent the mobile platform from shifting. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figures 1 to 3 The present invention provides an embodiment of a fire-fighting robot, including a mobile platform 1, which is designed to provide good mobility. A spraying mechanism 2 is provided on the top of the mobile platform 1. A connecting pipe 3 is fixedly connected to the top of the mobile platform 1. Through the connection of the connecting pipe 3, water can be transported into the interior of the mobile platform 1 and then flow out from the outside of the spraying mechanism 2. A disassembly mechanism 4 is provided on the top of the connecting pipe 3. A docking pipe 7 is fixedly connected to the top of the disassembly mechanism 4. The design provides good docking capability, which enables water to be stably transported into the interior of the connecting pipe 3. A blocking component 8 is provided on the outer side of the mobile platform 1.

[0043] The disassembly mechanism 4 includes two locking rings 41. The locking rings 41 are designed to provide good support, pressing down on the connection between the connecting pipe 7 and the connecting tube 3 to ensure stable connection. The locking rings 41 are slidably connected to the top of the connecting tube 3. Support blocks 42 are fixedly connected to both sides of the locking rings 41, providing good support and allowing for a seal at the connection of the connecting pipe 7 by pressing the support blocks 42. A rotating rod 43 is rotatably connected to the bottom of the support blocks 42, providing good rotation and support capabilities. A rotating column is rotatably connected to an adjacent side of the rotating rod 43. 45. Supported by two rotating rods 43, the rotating column 45 can rotate smoothly. A convex wheel 46 is fixedly connected to the outside of the rotating column 45. The convex wheel 46 can rotate due to the support of the rotating column 45, so that the rotating column 45 can drive the convex wheel 46 to rotate. A prying plate 47 is fixedly connected to the outside of the convex wheel 46. Its design provides good prying ability, so that pressing the prying plate 47 can drive the convex wheel 46 to rotate. A support block 48 is fixedly connected to the top of the connecting pipe 3. Its design provides good support ability. After the convex wheel 46 rotates, the convex surface of the convex wheel 46 can be put into contact with the bottom of the support block 48, which will then pull the support block 42 forward. Press down on the connection of the connecting pipe 7. The top of the support block 48 is slidably connected to the sliding frame 44. After the actuating plate 47 is rotated, the sliding frame 44 can limit the actuating plate 47, so that the convex wheel 46 can keep pressing and fixing the bottom of the support block 48. The bottom of the sliding frame 44 is fixedly connected to the reset component 5. The reset component 5 includes a guide post 501, which is designed to provide good guiding ability. The top of the guide post 501 is fixedly connected to the bottom of the sliding frame 44. The outside of the guide post 501 is fitted with a reset spring 502. The reset spring 502 is designed to generate a reset ability through its own force. After first pushing the sliding frame 44 upward, the two sides of the sliding frame 44 are slid against the actuating plate. The interior of 47 allows for limiting the movement of the prying plate 47. The top of the guide post 501 is fixedly connected to the top of the support block 48. The top of the locking ring 41 is slidably connected to the connecting component 6. The connecting component 6 includes two connecting posts 602, which are designed to provide good connection capability. By sliding the two locking rings 41 on their adjacent sides respectively, the two locking rings 41 can be fixed. After fixing, the locking rings 41 can easily engage with the connecting tube 7. The exterior of the two connecting posts 602 is slidably connected to the interior of the locking ring 41. The top of the two connecting posts 602 is fixedly connected to the sliding plate 601. The sliding plate 601 can quickly drive the two connecting posts 602 on the same side to slide and engage together.

[0044] Specifically, firstly, the locking ring 41 uses its bottom support block 42 to press against the connection between the connecting pipe 7 and the connecting tube 3, thereby maintaining a stable connection of the connecting pipe 7. When further fixing of the connecting pipe 7 is required, the operator moves the lever plate 47, which causes the convex wheel 46 to start rotating. As the convex wheel 46 rotates, its convex surface gradually comes into contact with the bottom of the support block 48, forming a tight contact. During continued rotation, the convex wheel 46 exerts a squeezing effect on the bottom of the support block 48, while simultaneously pulling the support block 42, further enhancing the sealing effect at the connection of the connecting pipe 7. When the lever plate 47 rotates to the designated position, the sliding frame 44 limits the lever plate 47, ensuring that the convex wheel 46 can continuously maintain the squeezing state on the bottom of the support block 48, thereby achieving a firm fixation of the connecting pipe 7. The return spring 502 then begins to function. After the disassembly operation is completed, through the elastic force of the return spring 502, the sliding frame 44 can automatically slide and enter the interior of the lever plate 47 for limiting and fixing. Simultaneously, the connecting column 602 and the sliding plate 601 cooperate to fix the locking ring 41. By sliding the two locking rings 41 on their adjacent sides, the two locking rings 41 can be fixed at the same time, ensuring that the locking rings 41 can firmly engage the connecting pipe 7, thereby completing the stable installation and fixing process of the connecting pipe 7 on the connecting pipe 3.

[0045] Reference Figure 1 and Figure 4 The spraying mechanism 2 includes two telescopic rods 21, which are designed to provide good telescopic capacity. The bottom of the two telescopic rods 21 is fixedly connected to the top of the moving platform 1. The output end of the two telescopic rods 21 is fixedly connected to a support plate 22, which is designed to provide stable support capacity. The top of the support plate 22 is fixedly connected to an adjustable nozzle 23, which is designed to provide good spraying capacity. Water is supplied to the inside of the connecting pipe 3 through the connecting pipe 7, and then flows into the inside of the adjustable nozzle 23 to spray the sprayed area. The top of the moving platform 1, that is, the side near the outside of the two telescopic rods 21, is fixedly connected to an adjusting rod 24, which is designed to provide different height adjustments. The output end of the adjusting rod 24 is fixedly connected to a self-spraying nozzle 25, which is designed to spray the moving platform 1 itself to cool it down. The outside of the adjusting rod 24 is between the connecting pipe 3 and the adjustable nozzle 23.

[0046] Specifically, during operation, the mobile platform 1 first reaches the fire scene via its mobility. The spraying mechanism 2 on top of the mobile platform 1 then operates, with two internal telescopic rods 21 extending and retracting according to the height of the fire source. This adjusts the height of the adjustable nozzles 23 on the support plate 22, thereby adjusting the spray angle and intensity to direct the extinguishing agent towards the fire source. Simultaneously, the self-spraying nozzles 25 on the adjusting rod 24 automatically sense changes in the temperature or pressure of the fire source, assisting in the spraying of the extinguishing agent. Regarding water supply, external water enters the connecting pipe 3 through the connection of the connecting pipe 7 and the disassembly mechanism 4, and is then transported to the interior of the mobile platform 1 to provide water for the spraying mechanism 2.

[0047] Reference Figure 4 and Figure 5 The blocking component 8 includes two sliding rods 81, which are designed to provide good guiding ability. The two sliding rods 81 are fixedly connected to the outside of the moving platform 1, that is, the outside side near the connecting pipe 3. The two sliding rods 81 are slidably connected to the outside of the support plate 82. The support plate 82 can slide smoothly through the guiding ability provided by the sliding rods 81. The bottom of the support plate 82 is fixedly connected to a limiting plate 85, which is designed to provide good support. The top of the limiting plate 85 is fixedly connected to multiple connecting columns 83. The limiting plate 85 provides good guiding ability for the connecting columns 83. The outside of the multiple connecting columns 83 is respectively fitted with a buffer spring 84, which provides good buffer ability and can withstand different terrains. The bottom of the multiple connecting columns 83 is fixedly connected to a friction block 86. The friction between the friction block 86 and the ground can prevent the moving platform 1 from moving backward due to excessive water flow.

[0048] Specifically, when the mobile platform 1 is subjected to the impact force from the water spray, the support plate 82 will be under pressure and slide inward. At this time, the buffer spring 84 on the connecting column 83 is compressed. The buffer spring 84 absorbs the impact energy through its own elastic deformation, thereby reducing the impact on the mobile platform 1. The limiting plate 85 provides support for the connecting column 83 and ensures that the connecting column 83 remains stable during the buffering process, preventing the connecting column 83 from shifting. During the movement of the mobile platform 1, the friction block 86 is in continuous contact with the ground, providing stable friction and enhancing the stability of the mobile platform 1 when turning or braking, preventing sideslip. When the mobile platform 1 encounters uneven ground or obstacles, the support plate 82 can slide up and down to adjust according to the changes in terrain. The buffer spring 84 is compressed when the support plate 82 slides, thereby adapting to different terrain conditions and maintaining the smooth movement of the mobile platform 1. When the robot completes its task and leaves the fire scene, the support plate 82 slides back to its initial position on the slide bar 81, and the buffer spring 84 returns to its original state, preparing for the next protection.

[0049] Working principle: The locking ring 41 presses down on the connection between the connecting pipe 7 and the connecting tube 3 via the support block 42 at its bottom, ensuring a secure connection of the connecting pipe 7. To further secure the connecting pipe 7, the operator needs to operate the lever plate 47, which drives the convex wheel 46 to rotate. As the convex wheel 46 rotates, its protruding part gradually fits tightly against the bottom of the support block 48. During rotation, the convex wheel 46 applies pressure to the bottom of the support block 48, while simultaneously driving the support block 42 to move, further enhancing the sealing performance of the connection between the connecting pipe 7 and the connecting pipe 7. When the lever plate 47 rotates to the predetermined position, the sliding frame 44 fixes the lever plate 47, ensuring that the convex wheel 46 can continuously apply pressure to the bottom of the support block 48, achieving reliable fixation of the connecting pipe 7. After the disassembly of the connecting pipe 7 is completed, the return spring 502 begins to function. With the elastic force of the return spring 502, the sliding frame 44 can automatically slide and embed itself inside the lever plate 47 for fixation. At the same time, the connecting column 602 and the sliding plate 601 cooperate to fix the locking ring 41. By sliding the two locking rings 41 on their adjacent sides, the two locking rings 41 can be fixed at the same time, ensuring that the locking rings 41 can firmly lock the connecting pipe 7, thereby completing the stable installation and fixing process of the connecting pipe 7;

[0050] Mobile platform 1 reaches the fire scene using its mobility. Then, the spraying mechanism 2 located on top of mobile platform 1 is activated. At this time, the two telescopic rods 21 inside the spraying mechanism 2 extend and retract according to the height of the fire source. The movement of the telescopic rods 21 causes the adjusting nozzles 23 on the support plate 22 to rise or fall until the adjusting nozzles 23 are at a suitable height. After reaching the designated height, the adjusting nozzles 23 adjust the spray angle and intensity according to actual needs, accurately spraying the extinguishing medium towards the fire source to carry out firefighting operations. Simultaneously, the automatic sprinkler heads 25 on the adjusting rods 24 automatically sense changes in the temperature or pressure of the fire source. When preset conditions are met, the automatic sprinkler heads 25 automatically open to assist in spraying the extinguishing medium and enhance the firefighting effect. Throughout the process, the water supply comes from outside. The external water source smoothly enters the connecting pipe 3 through the docking pipe 7 and the disassembly mechanism 4. Subsequently, the water source is transmitted to the interior of mobile platform 1 through the connecting pipe 3, thereby providing stable water support for the spraying mechanism 2, ensuring the continuous operation of the spraying mechanism 2 and providing a guarantee for firefighting work.

[0051] When the mobile platform 1 is impacted by the recoil of the water spray, the support plate 82 slides inward under pressure. At this time, the buffer spring 84 on the connecting column 83 is compressed and contracts, absorbing the impact energy through its own elastic deformation, thereby reducing the impact force on the mobile platform 1. During this process, the limiting plate 85 provides stable support for the connecting column 83, ensuring that the connecting column 83 does not shift during the buffering. When the mobile platform 1 is moving, the friction block 86 is in close contact with the ground, generating friction, enhancing the stability of the mobile platform 1 when turning or braking, and effectively preventing sideslip. When facing uneven ground or obstacles, the support plate 82 slides up and down to adjust according to the terrain. The buffer spring 84 is compressed as the support plate 82 slides, adapting to different terrains and maintaining the smooth movement of the mobile platform 1. After the task is completed, the support plate 82 slides back to the initial position along the slide bar 81, and the buffer spring 84 returns to its original position, ready for the next protection.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
