Description

Technical Field

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

[0002] To improve the efficiency of timely and effective rescue and reduce the risk of casualties, firefighting robots will be used to replace firefighters in entering dangerous disaster and accident sites.

[0003] Traditional firefighting operations mainly rely on manual operation in conjunction with heavy equipment, which has significant drawbacks: in complex fire environments, firefighters must face high temperatures, toxic fumes, and the risk of collapse.

[0004] While existing firefighting robot technology has partially replaced human labor, it has some shortcomings. The thermal protection system of existing equipment mostly uses single-layer ceramic fiber, which is prone to structural embrittlement during continuous fire operations, resulting in short working time and severely restricting combat effectiveness. At the same time, the output end of existing firefighting robots uses water spray pipes for fire rescue. Due to the complex fire scene environment, if the water spray pipes are kept open for a long time, they may become blocked during the process of entering the fire scene, thereby affecting the normal water output of the water spray pipes and thus affecting fire rescue work.

[0005] Based on this, a vehicle-mounted firefighting robot is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a vehicle-mounted firefighting robot to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is: a vehicle-mounted fire extinguishing robot, including a dual-degree-of-freedom water spray mechanical pipe module and a vehicle body. The dual-degree-of-freedom water spray mechanical pipe module is installed on the vehicle body and includes a lateral rotation mechanism, a longitudinal adjustment mechanism and a composite spray control system.

[0008] A lateral rotation mechanism, which is driven by a servo motor;

[0009] A longitudinal adjustment mechanism, wherein the longitudinal adjustment mechanism uses a worm gear transmission to drive the water spray pipe to achieve pitch angle adjustment;

[0010] A composite injection control system, comprising an integrated pressure sensor and an electromagnetic flow meter.

[0011] In some embodiments, the output end of the dual-degree-of-freedom water spray mechanical pipe module is fixedly connected to a water spray pipe, and a three-level thermal protection structure is provided on the outside of the water spray pipe.

[0012] In some embodiments, the front end of the vehicle body is equipped with an infrared thermal imager and a high-definition camera, which are electrically connected to the composite injection control system. The vehicle body is also equipped with warning lights and an alarm sound, which are controlled by the composite injection control system to send or cancel hazard signals. The vehicle body is also equipped with a positioning module, which is electrically connected to the composite injection control system.

[0013] In some embodiments, a fire hydrant is fixedly connected to the surface of the vehicle body, the water spray pipe is connected to a water inlet pipe inside the vehicle body, and the water inlet pipe is connected to the fire hydrant on the vehicle body.

[0014] In some embodiments, a chassis is provided on the lower surface of the vehicle body, the chassis is tracked, and the vehicle body is equipped with crash barriers.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this invention utilizes a composite spray control system that can automatically switch pulse spray modes based on the type of fire. When a lithium battery fire is detected, it can rapidly reduce the surface temperature of the lithium battery, effectively suppressing the spread of the fire. The infrared thermal imager and high-definition camera at the front of the vehicle are electrically connected to the composite spray control system, enabling real-time monitoring of temperature distribution and visual information at the fire scene. This helps the control system quickly and accurately locate the fire source, improving fire extinguishing efficiency. The composite spray control system integrates three fire extinguishing mechanisms: cooling, suffocation, and blowing off, maximizing the fire extinguishing efficiency of the extinguishing agent. The vehicle uses a tracked chassis, providing excellent obstacle-crossing ability and traction, allowing it to adapt to various complex terrains.

[0017] Secondly, the movable cover plate in this utility model can protect the water spray pipe. When entering the fire scene and reaching the designated rescue position, the water source can be activated to introduce water into the water spray pipe. Through the set conical cylinder, the water flow can be converged before the water flow is output, thereby increasing the impact force of the water flow. While driving the impeller to rotate, the water flow can open the movable cover plate to realize the rescue work. During the rotation of the impeller, it will drive the rotating ring to rotate, thereby driving the rotating seat and the movable cover plate to rotate. When the movable cover plate rotates, the baffle set on the movable cover plate can cut the water flow, thereby increasing the impact area of ​​the water flow. Combined with the rotational motion, the rescue area is further increased. The movable cover plate is connected by a torsion spring shaft. When the water flow is turned off, the torsion spring shaft drives the movable cover plate to automatically reset and cover the water spray pipe again for protection. Attached Figure Description

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved vehicle-mounted firefighting robot. The technical solution of this utility model is as follows: Example

[0027] like Figure 1As shown, a vehicle-mounted fire extinguishing robot includes a dual-degree-of-freedom (DOF) water spray mechanical pipe module 1 and a vehicle body 6. The dual-DOF water spray mechanical pipe module 1 is mounted on the vehicle body 6, and its output end is fixedly connected to a water spray pipe 2. The water spray pipe 2 has a three-level thermal protection structure on its outer side, consisting of an outer layer, a middle layer, and an inner layer. The dual-DOF water spray mechanical pipe module 1 includes a lateral rotation mechanism 10, a longitudinal adjustment mechanism 4, and a composite spray control system 3. The lateral rotation mechanism 10 is driven by a servo motor and contains a harmonic reducer, an absolute encoder, and a crossed roller bearing. It can achieve 360-degree continuous rotation, enabling rapid omnidirectional scanning of the fire source at a fire scene, and can quickly adjust its position regardless of the fire source's direction. The water spray direction for fire extinguishing greatly improves fire extinguishing efficiency and response speed. The longitudinal adjustment mechanism 4 uses a worm gear drive to drive the water spray pipe 2 to achieve pitch angle adjustment. The composite spray control system 3 includes an integrated pressure sensor and an electromagnetic flow meter. The front of the vehicle body 6 is equipped with an infrared thermal imager 9 and a high-definition camera, which are electrically connected to the composite spray control system 3. The vehicle body 6 is also equipped with alarm lights and alarm sounds, as well as a positioning module, which is electrically connected to the composite spray control system 3. The infrared thermal imager 9 and high-definition camera at the front of the vehicle body 6 can monitor the temperature distribution and visual information of the fire scene in real time, helping the control system to quickly locate the fire source and improve fire extinguishing efficiency. The vehicle body 6 is also equipped with alarm lights and alarm sounds, controlled by the control system based on danger signals or the elimination of danger signals. It can promptly issue an alarm when a dangerous situation is detected, alerting on-site personnel to safety. A fire extinguishing interface 7 is fixedly connected to the surface of the vehicle body 6. The water spray pipe 2 connects to the water inlet pipe inside the vehicle body 6, which in turn connects to the fire extinguishing interface 7 on the vehicle body 6. The fire extinguishing interface 7 is a quick-change interface, compatible with water-based fire extinguishing nozzles, dry powder spray devices, and foam generators. This structural design ensures the stability and reliability of the water spraying system, facilitates rapid connection to external fire water sources, and improves the robot's deployment efficiency at fire scenes. A chassis 8 is installed on the lower surface of the vehicle body 6. The chassis 8 is tracked, and the vehicle body 6 is equipped with crash barriers 5. The crash barriers 5 provide additional protection during robot movement, preventing equipment damage due to collisions and improving the robot's safety in complex environments.

[0028] The specific working method is as follows: First, the robot is placed near the fire scene to ensure it is in a stable state. The infrared thermal imager 9 and high-definition camera at the front of the vehicle body 6 monitor the fire scene in real time, quickly locating the fire source. Simultaneously, the gas composition analysis module detects the gas composition at the fire scene, assisting in determining the fire type. When a lithium battery fire is detected, the composite spray control system 3 automatically switches to pulse spray mode, rapidly reducing the surface temperature of the lithium battery and effectively suppressing the fire's spread. During firefighting, operators can monitor the robot's status via a remote control terminal and manually adjust the spray mode or intervene in the robot's actions as needed. The robot chassis 8 adopts a tracked design, possessing excellent obstacle-crossing ability and traction, adapting to complex terrain and quickly reaching designated locations. The water spray mechanical pipe module is installed at the front of the vehicle body 6. The water spray pipe 2 is connected to the water inlet pipe inside the vehicle body 6. The water inlet pipe connects to an external fire water source via a quick-connect interface, compatible with water-based fire extinguishing nozzles, dry powder spray devices, and foam generators, improving the robot's applicability in different fire scenarios. Example

[0029] Based on Example 1, and referring to... Figures 2-4 As shown, one end of the water spray pipe 2 is rotatably connected to a movable cover plate 11 via a rotating seat 18. A torsion spring shaft is fixedly installed on the inner wall of the rotating seat 18. The movable cover plate 11 is fixedly connected to the surface of the torsion spring shaft. A stop bar 12 is fixedly connected to one side of the movable cover plate 11. The movable cover plate 11 can be automatically closed when the water flow is turned off by the torsion spring shaft. The stop bar 12 can cut the water flow, thereby increasing the spraying area.

[0030] A conical cylinder 16 is fixedly connected to the inner wall of the water spray pipe 2. A sealing ring 14 is fixedly connected to one end of the movable cover plate 11. An annular groove is opened on one side of the sealing ring 14. A rotating ring 13 is rotatably connected to the inner wall of the annular groove. The conical cylinder 16 can improve the impact force of the water flow, thereby improving the rotation efficiency of the impeller 17.

[0031] One side of the rotating ring 13 is fixedly connected to one side of the rotating seat 18. A connecting seat is fixedly connected to the inner wall of the rotating ring 13, and an impeller 17 is fixedly connected to the surface of the connecting seat.

[0032] The specific working method is as follows: Before entering the fire scene, the movable cover plate 11 can protect the water spray pipe 2. When entering the fire scene and reaching the designated rescue position, the water source can be activated to introduce water into the water spray pipe 2. Through the set cone 16, the water flow can be converged before the water flow is output, thereby increasing the impact force of the water flow. While driving the impeller 17 to rotate, the water flow can open the movable cover plate 11 to realize the rescue work. During the rotation of the impeller 17, it will drive the rotating ring 13 to rotate, thereby driving the rotating seat 18 and the movable cover plate 11 to rotate. When the movable cover plate 11 rotates, the baffle set on the movable cover plate 11 can cut the water flow, thereby increasing the impact area of ​​the water flow. Combined with the rotational motion, the rescue area is further increased. The movable cover plate 11 is connected by a torsion spring shaft. When the water flow is turned off, the torsion spring shaft can drive the movable cover plate 11 to automatically reset and cover the water spray pipe 2 again for protection.
