Description

Technical Field

[0001] This utility model relates to the field of inspection robots, specifically a prefabricated fire extinguishing device for substation inspection robots. Background Technology

[0002] The tracked fire inspection robot is an intelligent piece of equipment designed specifically for high-risk environments. Combining the all-terrain mobility of the tracked chassis with multi-sensor fusion technology, it enables fire source detection, environmental monitoring, and real-time data transmission. Its modular design supports functional expansion, such as high-flow water cannons, autonomous navigation and obstacle avoidance, and multi-robot collaborative operations. It is suitable for scenarios such as petrochemical plants, tunnels, and high-rise buildings, effectively replacing manual labor in flammable, explosive, high-temperature, and toxic areas, and reducing rescue risks.

[0003] Current fire-fighting inspection robots are typically assembled and connected to external fire hydrants. Using thermal imaging components such as infrared cameras and radar obstacle avoidance systems mounted on top of the robot, they detect areas of high-temperature combustion, move to the burning area, and spray fire-fighting water into the burning area via valve control to extinguish the fire. However, a problem exists in actual use: specifically, the liquid pressure inside the external fire hydrants is high. If the valves open too quickly, a rapid water flow can cause water hammer impact on the robot, increasing the risk of damage to its internal precision components. Therefore, the inventors urgently need to design an assembly structure that can reduce the impact damage of water hammer on the robot, thereby improving the protection of the inspection robot. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a prefabricated fire extinguishing device for substation inspection robots, so as to solve the technical problem of water hammer impact faced by fire inspection robots when connected to high-pressure fire pipelines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated fire extinguishing device for a substation inspection robot, comprising a robot body, a nozzle part installed on one side of the top of the robot body, and a connecting part installed at the tail end of the robot body. The connecting part includes a first connecting pipe and a second connecting pipe, a flexible hose is flange-connected between the first connecting pipe and the second connecting pipe, and a support rod is inserted through the flange mounting bolt holes at both ends of the flexible hose to support the flexible hose. The flexible hose is used to absorb the impact force of water hammer.

[0006] By adopting the above technical solution, the problem of high-pressure fluid impact is solved by the modular design of the connection part: the tail end of the robot body is equipped with a first connecting pipe and a second connecting pipe, and a flexible hose connected by a flange directly absorbs the water hammer impact energy, which significantly reduces the vibration damage of pressure fluctuations to the precision electronic components inside the robot.

[0007] Furthermore, the first connecting pipe is connected to the nozzle, and the other end of the second connecting pipe is connected to the external fire water pipe in a quick-connect structure.

[0008] By adopting the above technical solutions, the direct-connection flow channel design of the first connecting pipe and the nozzle ensures that the fire extinguishing water flow path is minimized, reducing pressure loss and improving spraying efficiency. At the same time, the quick-connect structure at the end of the second connecting pipe enables instantaneous locking and separation from the external fire water pipe, which not only meets the rapid response requirements of fire extinguishing scenarios, but also ensures the robot's mobility during emergency evacuation.

[0009] Furthermore, a buffer rod is fixedly installed in the middle of the support rod, and both the buffer rod and the flexible hose are made of rubber.

[0010] By adopting the above technical solution, the rubber material and the flexible hose form an elastic synergy. When water hammer occurs, the two undergo compression deformation simultaneously, converting the transient high pressure into continuously released elastic potential energy, thus avoiding pipe rupture caused by local stress concentration.

[0011] Furthermore, the buffer bar can exhibit two, but is not limited to, two, elasticity characteristics.

[0012] By adopting the above technical solution, and by limiting the buffer bar to have two or more elasticity characteristics, the high elasticity section preferentially absorbs low-intensity pulses, while the high-intensity section copes with extreme pressure peaks, thus adaptively matching the impact intensity under different working conditions.

[0013] Furthermore, the second connecting pipe has a "Z" shaped structure, and a water hammer eliminator is installed on the flange of the second connecting pipe.

[0014] By adopting the above technical solution, the "Z"-shaped structure layout of the second connecting pipe actively consumes fluid kinetic energy through two flow direction turns, extends the shock wave transmission path, and reduces the pressure wave front steepness.

[0015] Furthermore, a support platform is provided on the top of the robot body, and an infrared detection component is movably connected to the top of the support platform through a drive mechanism for detecting the location of the fire.

[0016] By adopting the above technical solution, the support platform provides a lifting base for the infrared detection component, expanding the pitch range of fire source scanning. At the same time, the drive mechanism enables precise positioning of the detection component with multiple degrees of freedom. Through 360° horizontal rotation and pitch angle adjustment, it can cover densely populated areas of substation equipment without blind spots and quickly lock hidden fire points.

[0017] Furthermore, a baffle is fixedly installed on the front side of the robot body. The baffle has a "V" shape and is used to push aside obstacles.

[0018] By adopting the above technical solution, the front layout of the "V"-shaped baffle optimizes obstacle handling capability through geometric and mechanical design: its pointed forked structure wedges into the bottom of the obstacle during the robot's movement, and uses the principle of inclined plane mechanics to convert horizontal thrust into oblique thrust, easily clearing away low debris such as cables and gravel.

[0019] Furthermore, an electrically controlled valve is installed on the nozzle section, and the electrically controlled valve is electrically connected to the internal battery power supply through a controller. Moving parts are driven and arranged on both sides of the lower part of the robot body.

[0020] By adopting the above technical solution, the integration of the electronically controlled valve enables intelligent flow control of the nozzle: the controller dynamically adjusts the spray angle and water flow intensity based on the fire data fed back by the infrared detection component, avoiding energy waste and water damage caused by ineffective spraying.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention utilizes a connecting section where the robot body directly absorbs the water hammer impact force generated by sudden changes in water flow through a flexible hose, reducing vibration damage to internal precision components caused by high-pressure water. Simultaneously, a support rod penetrating the hose flange provides structural constraints, preventing hose twisting or breakage and ensuring pipeline stability. Furthermore, the "Z"-shaped structure of the second connecting pipe forms a multi-stage buffering mechanism with the water hammer eliminator, weakening pressure fluctuations through flow direction changes and passive energy dissipation. Additionally, the buffer rod and the rubber of the flexible hose deform in tandem, further converting impact kinetic energy and extending component lifespan. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1:

[0030] Substation inspection robots and prefabricated fire extinguishing devices, such as Figure 1-4 As shown, the robot includes a main body 1, a nozzle 5 mounted on one side of the top of the main body 1, and a connecting part 6 mounted at the tail end of the main body 1. The connecting part 6 includes a first connecting pipe 601 and a second connecting pipe 602. A flexible hose 603 is flanged between the first connecting pipe 601 and the second connecting pipe 602. Support rods 604 are inserted through the flange mounting bolt holes at both ends of the flexible hose 603 to support the flexible hose 603. The flexible hose 603 is used to absorb the impact force of water hammer. The modular design of the connecting part 6 solves the problem of high-pressure fluid impact: the first connecting pipe 601 and the second connecting pipe 602 are configured at the tail end of the main body 1, and the flexible hose 603 connected by flanges directly absorbs the impact energy of water hammer, significantly reducing the vibration damage of pressure fluctuations to the precision electronic components inside the robot. At the same time, the support rods 604 inserted through the flanges at both ends of the flexible hose 603 provide axial rigidity constraint while allowing radial deformation of the hose, ensuring the stability of the pipe connection and preventing the hose from twisting and breaking due to high-pressure impact. This dual protection mechanism greatly improves the structural reliability of the robot in high-pressure fire fighting operations and extends the service life of the equipment.

[0031] See Figure 2 , Figure 3 , Figure 4 The first connecting pipe 601 is connected to the nozzle section 5, and the other end of the second connecting pipe 602 is connected to the external fire water pipe in a quick-connect structure. The direct connection flow channel design between the first connecting pipe 601 and the nozzle section 5 ensures that the fire extinguishing water flow path is minimized, reducing pressure loss and improving spraying efficiency. At the same time, the quick-connect structure at the end of the second connecting pipe 602 enables instantaneous locking and separation from the external fire water pipe, which not only meets the rapid response requirements of fire extinguishing scenarios, but also ensures the robot's mobility during emergency evacuation. This connection method avoids the time loss and sealing failure risk of traditional threaded connections. Combined with the buffering capacity of the flexible hose 603, it forms a full-link impact-resistant protection from the external water source to the spraying terminal, enhancing the system's adaptability in dynamic operations.

[0032] See Figure 2 , Figure 3 , Figure 4A buffer rod 605 is fixedly installed in the middle of the support rod 604. Both the buffer rod 605 and the flexible hose 603 are made of rubber. The rubber material and the flexible hose 603 form an elastic synergy. When water hammer occurs, the two undergo compression deformation simultaneously, converting the transient high pressure into continuously released elastic potential energy, avoiding pipe rupture caused by local stress concentration. At the same time, the rubber has both corrosion resistance and fatigue resistance properties, adapting to the chemical corrosive media in the fire protection environment, reducing the aging rate of components, ensuring that the buffer system maintains functional stability under long-term repeated impacts, and reducing operation and maintenance costs.

[0033] See Figure 2 , Figure 3 , Figure 4 The buffer rod 605 exhibits two, but not limited to, elasticity characteristics. By limiting the buffer rod 605 to possess more than two elasticity characteristics, the high-elasticity section preferentially absorbs low-intensity pulses, while the high-intensity section copes with extreme pressure peaks, adaptively matching the impact intensity under different working conditions. At the same time, this design supports the customization of elastic modulus combinations according to actual needs, and optimizes the buffer curve through physical tuning to avoid the resonance effect of a single material on shock waves of a specific frequency, significantly improving the universality and accuracy of water hammer suppression, and is especially suitable for industrial scenarios with complex pressure fluctuations in fire protection pipelines.

[0034] Example 2:

[0035] See Figure 2 , Figure 3 , Figure 4 The second connecting pipe 602 has a "Z" shaped structure. A water hammer eliminator 8 is installed on the flange of the second connecting pipe 602. The "Z" shaped structure of the second connecting pipe 602 actively consumes fluid kinetic energy through two flow direction turns, prolongs the shock wave transmission path, and reduces the pressure wave front steepness. At the same time, the water hammer eliminator 8 installed on the flange complements the "Z" shaped pipe: the former absorbs high-frequency pulses through compressed gas or elastic diaphragm, while the latter focuses on low-frequency energy dissipation. The double superimposed elimination mechanism covers the pressure fluctuation of the entire frequency band. This structure avoids the impact reflection superposition problem of the traditional straight pipe layout, and is especially suitable for the instantaneous high pressure change generated when the robot quickly opens and closes the valve.

[0036] See Figure 1 , Figure 2 , Figure 3The robot body 1 has a support platform 2 on its top. The top of the support platform 2 is movably connected to the infrared detection component 4 through the drive mechanism 3. The infrared detection component 4 is used to detect the location of the fire. The support platform 2 provides a lifting base for the infrared detection component 4, expanding the fire source scanning pitch range. At the same time, the drive mechanism 3 realizes the multi-degree-of-freedom precise positioning of the detection component. Through 360° horizontal rotation and pitch angle adjustment, it can cover the densely equipped area of ​​the substation without blind spots and quickly lock the hidden fire point. This structure integrates thermal imaging and visible light detection modules on the same motion platform to ensure the real-time linkage between fire identification accuracy and fire extinguishing path planning.

[0037] See Figure 1 , Figure 2 , Figure 3 A baffle 9 is fixedly installed on the front side of the robot body 1. The baffle 9 has a "V" shaped structure and is used to push aside obstacles. The front layout of the "V" shaped baffle 9 optimizes obstacle handling capability through geometric and mechanical design: its pointed forked structure wedges into the bottom of the obstacle as the robot body 1 moves, and uses the principle of inclined plane mechanics to convert horizontal thrust into oblique thrust, easily pushing aside low debris such as cables and gravel. At the same time, the V-shaped angle enhances the structural rigidity, resists collision deformation, and protects the key components of the rear connecting part 6 and the moving part 7, ensuring the robot's passability and continuous combat capability in the complex terrain of the substation.

[0038] See Figure 1 , Figure 2 , Figure 3 The nozzle section 5 is equipped with an electrically controlled valve, which is electrically connected to the internal battery power supply through a controller. The robot body 1 has moving parts 7 driven on both sides of the lower part. The integration of the electrically controlled valve enables intelligent flow control of the nozzle section 5: the controller dynamically adjusts the spray angle and water flow intensity based on the fire data fed back by the infrared detection component 4, avoiding energy waste and water damage caused by ineffective spraying. At the same time, the drive design of the moving parts 7 provides the robot with all-terrain mobility. Combined with the autonomous power supply characteristics of the battery power supply, it ensures that the robot can still perform fire fighting tasks in substation power outages or high-risk environments.

[0039] The implementation principle of this embodiment is as follows: After the robot body 1 arrives at the target area through the moving part 7, the drive mechanism 3 on its support platform 2 drives the infrared detection component 4 to scan and locate the fire source; during fire extinguishing, the connecting part 6 connects the nozzle part 5 and the external fire pipeline through the first connecting pipe 601 and the second connecting pipe 602 respectively. During this process, the flexible hose 603 reinforced by the support rod 604 and the buffer rod 605 work together to absorb the impact force of water hammer. At the same time, the "Z"-shaped structure of the second connecting pipe 602 and the water hammer eliminator 8 further dissipate the pressure fluctuation; then the electrically controlled valve of the nozzle part 5 is opened in a controlled manner, and the water flow is stabilized to extinguish the fire accurately. During this period, the "V"-shaped baffle 9 continuously clears obstacles in the path. The whole process forms a closed-loop action chain through the infrared detection component 4, valve control and the moving part 7, so as to achieve effective protection of the robot's precision components.
