Description

Technical Field

[0001] This invention relates to the field of firefighting robot technology, and in particular to an intelligent firefighting robot based on the Internet of Things. Background Technology

[0002] Firefighting robots are specialized robots used for firefighting and rescue operations, primarily deployed in hazardous disaster sites such as chemical plants, tunnels, and subways. These robots often employ a tank-like tracked structure, equipped with explosion-proof materials, high-temperature resistant protection systems, and fire monitors. Core functions include remote control, autonomous navigation, environmental perception, and extinguishing agent spraying. The Internet of Things (IoT) refers to connecting any object to a network through information sensing devices and agreed-upon protocols. Objects exchange and communicate information through communication media to achieve intelligent identification, positioning, tracking, and monitoring functions. Firefighting robots can be controlled via the IoT.

[0003] In a fire, sudden impacts such as collisions and falling objects can easily damage the robot's outer shell. Traditional designs often employ a highly integrated structure for the shell and body; once damaged, disassembly and replacement are extremely cumbersome, resulting in high repair costs and significant time consumption. This severely restricts the robot's continuous operational capability, making it difficult for it to maintain its effectiveness in emergency fire situations. Furthermore, the extreme high temperatures of a fire environment can cause the robot to heat up rapidly in a short time, interfering with the stable operation of internal core components such as the control module, accelerating the aging and wear of these components, and significantly shortening its lifespan. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an intelligent firefighting robot based on the Internet of Things.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an intelligent fire-fighting robot based on the Internet of Things, comprising a vehicle body and a fire monitor and camera installed at the head of the vehicle body, a tracked walking system for movement installed at the bottom of the vehicle body, a water inlet pipe installed at the rear of the vehicle body, the vehicle body being trapezoidal in shape, and protective components installed on both sides and the top surface, the protective components including a fixed pipe installed on the vehicle body and protective boxes arranged in an array along the length of the fixed pipe, a first connecting pipe installed on the fixed pipe corresponding to the protective box, a circular hole opened on one side of the protective box, a second connecting pipe inserted into the circular hole and engaging with the first connecting pipe, a cooling pipe installed inside the protective box, one end of the cooling pipe connected to the second connecting pipe and the other end passing through the protective box, a plurality of heat sinks spaced apart inside the protective box, the plurality of heat sinks being connected to the cooling pipe, a fixing unit for fixing the protective box to the vehicle body installed on the side of the protective box away from the second connecting pipe, a delivery pipe connected to the water inlet pipe, and the delivery pipe connected to the fixed pipe.

[0006] By adopting the above technical solution, which includes a fixed pipe, a first connecting pipe, a protective box, and a cooling pipe, the protective box can actively absorb the surrounding high-temperature heat in a fire environment and transfer it to the internal heat sink, achieving initial heat dissipation. Simultaneously, the water introduced by the inlet pipe is diverted to the fixed pipe via the delivery pipe, and then, through the connection of the first and second connecting pipes, is delivered to the cooling pipe inside the protective box, ultimately exiting from the cooling pipe. The water carries away the heat from the heat sink during its flow. This process forms a water cooling system that continuously cools the protective box, effectively reducing the overall temperature of the vehicle and ensuring the stable operation of the robot's core components in high-temperature environments. Furthermore, when the protective box is damaged in a fire due to collisions, falling objects, or other impacts, simply operating the fixing unit to unlock it, and then sliding the protective box along the locking strip, easily separates the second connecting pipe from the first connecting pipe, allowing the damaged protective box to be removed and replaced. This design not only significantly reduces the maintenance cost and difficulty of the vehicle but, more importantly, enables the robot to restore its protective capabilities in a short time, significantly improving its survivability and continuous operation capability in complex fire environments.

[0007] Furthermore, the outer wall of the vehicle body is provided with a retaining strip for each first connecting pipe, and two heat dissipation strips are respectively provided on both sides of the retaining strip on the outer wall of the vehicle body. The four heat dissipation strips are arranged parallel to the retaining strips and perpendicular to the fixing pipe. The protective box is provided with a first retaining groove corresponding to the retaining strip, and the protective box is provided with a second retaining groove corresponding to the heat dissipation strip.

[0008] By adopting the above technical solution, a locking strip and a heat dissipation strip are installed. The locking strip can cooperate with the first slot of the protective box to position and initially fix the protective box, facilitating its installation and removal. The heat dissipation strip increases the heat dissipation area of ​​the vehicle body, allowing heat from the vehicle body to be transferred to the protective box, improving heat dissipation efficiency and enhancing the robot's heat resistance.

[0009] Furthermore, the length of the locking strip is greater than the length of the protective box. The fixing unit includes a fixing plate and a first control plate disposed on the side wall of the protective box away from the second connecting pipe. The fixing plate has a sliding hole, and a fixing rod is slidably disposed in the sliding hole. The locking strip has a locking hole on the side away from the fixing pipe. The fixing rod is inserted into the locking hole to fix the position of the fixing plate and the protective box. The fixing plate is parallel to the first control plate. A fixing shaft is disposed between the fixing plate and the first control plate. A sliding tube is slidably sleeved on the fixing shaft. A second control plate connected to the fixing rod is fixedly sleeved on the sliding tube. A compression spring is sleeved on the sliding tube. One end of the compression spring is connected to the first control plate and the other end is connected to the second control plate.

[0010] By adopting the above technical solution, a fixed plate, a first control plate, a fixed rod, a sliding tube, a second control plate, and a compression spring are set up. In the initial state, the thrust generated by the compression spring continuously acts on the second control plate, ensuring the stability of the sliding tube and the second control plate. In this state, the fixed rod is inserted into the locking hole of the locking strip, realizing a stable lock on the fixed plate and the protective box, ensuring the relative position of the protective box and the vehicle body is fixed.

[0011] Furthermore, when the second control plate contacts the fixed plate, the distance from the end of the sliding tube away from the fixed plate to the first control plate is the same as the distance from the end of the fixed rod away from the second control plate to the fixed plate.

[0012] By adopting the above technical solution, the stability and reliability of the fixed unit during operation are ensured.

[0013] Furthermore, the cooling pipe is generally coiled, with the end of the cooling pipe away from the connecting pipe passing through the middle of the protective box on the side away from the vehicle body. A rotating pipe is rotatably sleeved on the end of the cooling pipe that passes through the protective box. A sealing plate is provided at the end of the rotating pipe away from the protective box. Several mounting pipes are arranged circumferentially on the rotating pipe. The center line of the mounting pipe is perpendicular to the center line of the rotating pipe. A spray pipe is connected to the end of the mounting pipe away from the rotating pipe. The angle between the center line of the spray pipe and the center line of the mounting pipe is an obtuse angle.

[0014] By adopting the above technical solution, including the installation of a rotating tube, sealing plate, mounting tube, and spray pipe, and with the cooling tube arranged in a coil shape, the contact area between the cooling tube and the air inside the protective box and the heat sink is increased, thereby improving heat exchange efficiency and enhancing the cooling effect. When water is sprayed out from the spray pipe, it can cool the environment around the protective box, further reducing the temperature around the vehicle body.

[0015] Furthermore, the distance from the end of the nozzle furthest from the mounting pipe to the protective box is less than the distance from the end connected to the mounting pipe to the protective box.

[0016] By adopting the above technical solution, the distance from the end of the nozzle away from the mounting pipe to the protective box is less than the distance from the end connected to the mounting pipe to the protective box. This design allows the water jet from the nozzle to better cover the surface of the protective box, improving the water spraying cooling effect and ensuring that the protective box and the vehicle body are cooled more effectively.

[0017] Furthermore, a protective disc is provided on the sealing plate, and the orthographic projections of the mounting pipe and the spray pipe are both located within the bottom area of ​​the protective disc.

[0018] By adopting the above technical solution and setting up a protective disc, the protective disc can protect the rotating pipe, the mounting pipe and the nozzle, prevent them from being hit by debris at the fire scene, and ensure that the nozzle can spray water normally.

[0019] Furthermore, two annular grooves are formed on the inner wall of the second connecting pipe, and a sealing ring is provided in the annular groove.

[0020] By adopting the above technical solution, setting an annular groove and a sealing ring, the sealing ring can effectively improve the connection sealing between the second connecting pipe and the first connecting pipe, prevent water leakage at the connection point, ensure the normal operation of the cooling system, and guarantee the cooling effect.

[0021] Furthermore, an arc-shaped protective plate is provided on the outer wall of the vehicle body corresponding to the fixing pipe.

[0022] In summary, this invention offers the following advantages: The invention comprises a fixed pipe, a first connecting pipe, a protective box, and a cooling pipe. In a fire environment, the protective box actively absorbs the surrounding high-temperature heat and transfers it to the internal heat sink, achieving initial heat dissipation. Simultaneously, water introduced through the inlet pipe is diverted to the fixed pipe via the delivery pipe, then connected to the first and second connecting pipes, and finally discharged from the cooling pipe. The water carries away heat from the heat sink during its flow. This process forms a water cooling system that continuously cools the protective box, effectively reducing the overall temperature of the vehicle and ensuring the stable operation of the robot's core components in high-temperature environments. Furthermore, when the protective box is damaged in a fire due to collisions, falling objects, or other impacts, simply unlocking the fixing unit and sliding the protective box along the locking strip easily separates the second and first connecting pipes, allowing the damaged protective box to be removed and replaced. This design not only significantly reduces the maintenance cost and difficulty of the vehicle but, more importantly, enables the robot to quickly restore its protective capabilities, significantly enhancing its survivability and continuous operation in complex fire environments.

Detailed Implementation

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figure 1-8 As shown in the figure, this application discloses an IoT-based intelligent firefighting robot, including a vehicle body 10 and a fire monitor and camera installed at the head of the vehicle body 10. The bottom of the vehicle body 10 is equipped with a tracked walking system for movement, and the rear of the vehicle body 10 is equipped with a water inlet pipe 14. It should be noted that the camera, fire monitor, tracked walking system, and related technologies for control via an external remote control using the Internet of Things involved in this firefighting robot are all existing mature technologies, and therefore will not be described in detail here.

[0034] Specifically, the vehicle body 10 is trapezoidal in shape, with protective components on its two sides and top. These components include fixing pipes 20 and protective boxes 30. The fixing pipes 20 are fixedly installed on the outer wall of the vehicle body 10, and their length can be flexibly selected according to the size of the exposed surface of the vehicle body 10 that needs to be covered. Several protective boxes 30 are arranged in an array along the length of the corresponding fixing pipes 20 on the outer wall of the vehicle body 10. A first connecting pipe 21 is provided on the fixing pipe 20 corresponding to the protective box 30. A circular hole is opened on one side of the protective box 30, and a second connecting pipe 31, which inserts into the circular hole, mates with the first connecting pipe 21. Two annular grooves are formed on the inner wall of the second connecting pipe 31, and sealing rings 36 are installed in the annular grooves. The sealing rings 36 effectively improve the sealing performance between the second connecting pipe 31 and the first connecting pipe 21, preventing water leakage at the connection point. The protective box 30 is also equipped with a cooling pipe 32. One end of the cooling pipe 32 is connected to the second connecting pipe 31, and the other end passes through the protective box 30. Several heat sinks 33 are arranged at intervals inside the protective box 30, and all of the heat sinks 33 are connected to the cooling pipe 32. A delivery pipe 15 is connected to the water inlet pipe 14, and the delivery pipe 15 is connected to the fixing pipe 20 of the three protective components. A fixing unit 40 is provided on the side of the protective box 30 away from the second connecting pipe 31 to fix the protective box 30 to the vehicle body 10. In a fire environment, the protective box 30 can actively absorb the high temperature heat from the surrounding environment and transfer it to the heat sinks 33 inside, achieving initial heat dissipation. At the same time, the water flow introduced by the water inlet pipe 14 will be diverted to the fixing pipe 20 through the delivery pipe 15, and then delivered to the cooling pipe 32 inside the protective box 30 through the docking of the first connecting pipe 21 and the second connecting pipe 31, and finally discharged from the cooling pipe 32. During the process of water flow, the heat of the heat sinks 33 is carried away. This process forms a water cooling system that continuously cools the protective box 30, thereby effectively reducing the temperature of the entire vehicle body 10 and ensuring the stable operation of the robot's core components in high-temperature environments. Furthermore, when the protective box 30 is damaged in a fire due to collisions, falling objects, or other impacts, simply operate the fixing unit 40 to unlock it, then slide the protective box 30 along the locking strip 11 to easily separate the second connecting pipe 31 from the first connecting pipe 21, allowing the damaged protective box 30 to be removed and replaced. This design not only significantly reduces the maintenance cost and difficulty of the vehicle body 10, but more importantly, it allows the robot to restore its protective capabilities in a short time, significantly improving its survivability and continuous operation capability in complex fire scenes.

[0035] During installation, an arc-shaped protective plate 16 is installed on the outer wall of the vehicle body 10 corresponding to the fixed pipe 20. The arc-shaped protective plate 16 provides a protective barrier for the fixed pipe 20, effectively blocking sparks and falling foreign objects in the fire from directly impacting the fixed pipe 20, preventing deformation or damage to the fixed pipe 20 due to external impact. Through targeted protection of the fixed pipe 20, its water flow delivery function is ensured to continue stably in complex fire environments, providing reliable support for the cooling of the protective box 30.

[0036] A retaining strip 11 is provided on the outer wall of the vehicle body 10 corresponding to each first connecting pipe 21. The protective box 30 has a first retaining groove 34 corresponding to the retaining strip 11. The retaining strip 11 can cooperate with the first retaining groove 34 of the protective box 30 to position and initially fix the protective box 30, facilitating the installation and removal of the protective box 30. Two heat dissipation strips 13 are respectively provided on both sides of the retaining strip 11 on the outer wall of the vehicle body 10. The four heat dissipation strips 13 are arranged parallel to the retaining strip 11 and perpendicular to the fixing pipe 20. The protective box 30 has a second retaining groove 35 corresponding to the heat dissipation strips 13. The heat dissipation strips 13 increase the heat dissipation area of ​​the surface of the vehicle body 10, allowing the heat of the vehicle body 10 to be transferred to the protective box 30, improving heat dissipation efficiency and enhancing the heat resistance of the robot.

[0037] In specific configuration, the length of the locking strip 11 is greater than the length of the protective box 30. The fixing unit 40 includes a fixing plate 41 and a first control plate 42. Both the fixing plate 41 and the first control plate 42 are located on the side wall of the protective box 30 away from the second connecting pipe 31. The fixing plate 41 has a sliding hole, within which a fixing rod 43 is slidably mounted. The locking strip 11 has a locking hole 12 on the side away from the fixing pipe 20. The fixing rod 43 is inserted into the locking hole 12 to fix the positions of the fixing plate 41 and the protective box 30. The fixing plate 41 is parallel to the first control plate 42. A fixing shaft 44 is provided between the fixing plate 41 and the first control plate 42. A sliding tube 45 is slidably mounted on the fixing shaft 44. A second control plate 46, connected to the fixing rod 43, is fixedly mounted on the sliding tube 45, allowing the sliding tube 45, the second control plate 46, and the fixing rod 43 to move synchronously. A compression spring 47 is mounted on the sliding tube 45, with one end connected to the first control plate 42 and the other end connected to the second control plate 46. In the initial state, the thrust generated by the compression spring 47 continuously acts on the second control plate 46, ensuring the stability of the position of the sliding tube 45 and the second control plate 46. In this state, the fixing rod 43 is inserted into the locking hole 12 of the locking strip 11, realizing a stable lock on the fixing plate 41 and the protective box 30, ensuring the relative position of the protective box 30 and the vehicle body 10 is fixed. When installing the protective box 30, first push the second control plate 46 towards the first control plate 42, causing the fixing rod 43 to move synchronously. At this time, the compression spring 47 is compressed and stores elastic potential energy. Then, align the first slot 34 of the protective box 30 with the clip 11 of the vehicle body 10 and insert it smoothly. Next, slide the protective box 30 so that the first connecting pipe 21 on the fixing pipe 20 aligns with the second connecting pipe 31 of the protective box 30 and completes the insertion. Finally, release the second control plate 46, the compression spring 47 releases its elastic potential energy, and pushes the second control plate 46 and the fixing rod 43 to reset. Under the action of the spring, the fixing rod 43 automatically inserts into the clip hole 12, thereby firmly and tightly fixing the protective box 30 to the vehicle body 10 and ensuring the structural stability after installation.

[0038] When the second control plate 46 contacts the fixed plate 41, the distance from the end of the sliding tube 45 away from the fixed plate 41 to the first control plate 42 is the same as the distance from the end of the fixed rod 43 away from the second control plate 46 to the fixed plate 41. During the process of pushing the second control plate 46 towards the first control plate 42, the sliding tube 45 slides synchronously with the second control plate 46. When the end of the sliding tube 45 contacts the first control plate 42, the end of the fixed rod 43 is flush with the surface of the fixed plate 41, and at this time, the fixed rod 43 remains stably confined within the sliding hole and will not fall off. By controlling the movement stroke of the fixed rod 43, it is ensured that the fixed rod 43 can completely disengage from the locking hole 12 when the protective box 30 is disassembled and assembled, and the problem of the fixed rod 43 falling out of the sliding hole due to excessive operation is avoided, thereby ensuring the stability and reliability of the entire operation process.

[0039] The cooling pipe 32 is coiled in shape. The end of the cooling pipe 32 furthest from the connecting pipe exits through the middle of the protective box 30 on the side furthest from the vehicle body 10. A rotating pipe 50 is rotatably fitted onto the end of the cooling pipe 32 that exits the protective box 30. A rotary sealing structure is used between the rotating pipe 50 and the cooling pipe 32 to achieve dynamic sealing, effectively preventing water leakage at the rotation gap. Simultaneously, the rotary sealing assembly is made of a low-friction coefficient material, which significantly reduces the frictional resistance of the rotating pipe 50 relative to the cooling pipe 32 during rotation, ensuring sealing performance and allowing the rotating pipe 50 to rotate flexibly and smoothly around the axis of the cooling pipe 32. A sealing plate is provided at the end of the rotating pipe 50 away from the protective box 30. Several mounting pipes 51 are arranged circumferentially on the rotating pipe 50, and the mounting pipes 51 are connected to the rotating pipe 50. The center line of the mounting pipe 51 is perpendicular to the center line of the rotating pipe 50. A spray pipe 52 is connected to the end of the mounting pipe 51 away from the rotating pipe 50. The cooling pipe 32 is coiled, which can increase the contact area between the cooling pipe 32 and the air inside the protective box 30 and the heat sink 33, improve the heat exchange efficiency, and enhance the cooling effect. When water is sprayed out from the spray pipe 52, it can spray water to cool the environment around the protective box 30, further reducing the temperature around the vehicle body 10. The angle between the center line of the spray pipe 52 and the center line of the mounting pipe 51 is an obtuse angle. The water sprayed from the cooling pipe 32 enters the rotating pipe 50, passes through the mounting pipe 51, and is sprayed out from the spray pipe 52. Because the nozzle 52 and the mounting pipe 51 are designed at a preset angle, the reverse force generated when the water is sprayed will drive the nozzle 52, the mounting pipe 51, and the rotating pipe 50 to rotate around the center line of the rotating pipe 50. This dynamic rotation structure makes the water flow form a ring-shaped spray range, significantly expanding the water spray coverage area and achieving all-round cooling of the protective box 30 and the surrounding area, further improving the working efficiency of the cooling system. The distance from the end of the nozzle 52 away from the mounting pipe 51 to the protective box 30 is smaller than the distance from the end connected to the mounting pipe 51 to the protective box 30. This design allows the water sprayed from the nozzle 52 to better cover the surface of the protective box 30, improving the water spray cooling effect and ensuring that the protective box 30 and the vehicle body 10 are cooled more effectively. A protective disc 53 is provided on the sealing plate, and the orthographic projections of the mounting pipe 51 and the nozzle 52 are both located in the bottom area of ​​the protective disc 53. The protective disc 53 can protect the rotating pipe 50, the mounting pipe 51 and the nozzle 52, preventing them from being hit by debris at the fire scene and ensuring that the nozzle 52 can spray water normally.

[0040] The operating principle of the IoT-based intelligent firefighting robot in this embodiment is as follows: The robot is started via an external remote control using IoT technology. The tracked walking system begins to work, driving the vehicle body 10 to move. The fire monitor and camera at the head are activated, and the water inlet pipe 14 at the rear is connected to an external water source. After the vehicle body 10 enters the fire scene, the protective box 30 actively absorbs the surrounding high temperature and transfers it to the internal heat sink 33, initially dispersing the heat. At the same time, the water introduced by the water inlet pipe 14 is diverted to each fixed pipe 20 through the delivery pipe 15, and then enters the cooling pipe 32 inside the protective box 30 through the docking of the first connecting pipe 21 and the second connecting pipe 31. After the water carries away the heat from the heat sink 33, it is introduced into the cooling pipe 32, rotated through the rotating pipe 50, and sprayed out from the spray nozzle 52 through the installation pipe 51. The reaction force of the water flow drives the rotating pipe 50 to rotate, expanding the water spray cooling range and reducing the temperature of the vehicle body 10. If the protective box 30 is damaged, push the second control plate 46 to disengage the fixing rod 43 from the card hole 12, then slide the protective box 30 along the card strip 11 to separate the second connecting tube 31 from the first connecting tube 21, and remove the damaged protective box 30; when replacing the new protective box 30, align the card slot, insert and slide to mate the second connecting tube 31 with the first connecting tube 21, release the second control plate 46, and the fixing rod 43 will be inserted into the card hole 12 under the action of the compression spring 47 to complete the fixation.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
