[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0020] Reference Figures 1-7A tracked robot fire extinguishing device suitable for mountainous terrain includes a robot body 1 for fire extinguishing, a tracked chassis 5 at the bottom of the robot body 1 with wide tracks to increase the contact area with the ground and reduce the ground pressure, allowing it to easily cross obstacles such as ravines, slopes, and gravel, while also having good climbing ability to ensure flexible movement in mountainous photovoltaic power station scenarios, a fire monitoring camera 2 for monitoring the mountain photovoltaic power station, a rainwater collection tank 4 as a water source, a transformer substation maintenance compartment at the bottom of the water tank 4, which supplies power to the intelligent robot through a maintenance switch, a switch for building a local area network, and an industrial intelligent gateway for data acquisition and transmission. The robot body 1 and the rainwater collection tank 4 are connected by a fire hose 3. The fire monitoring camera 2 is connected to the robot body 1 through the switch and the industrial intelligent gateway. A control box 8 is located on the top of the robot body 1, and the control box 8 contains a PLC controller 9, which can use a Siemens S7-1200 CPU. The 1214C DC / DC / DC converter includes a motion control module 10, a communication module 11, and a fire monitor control module 12. The motion control module 10 regulates the movement and steering of the tracked chassis 5. The communication module 11 ensures bidirectional data transmission with the fire monitoring camera 2 and the control center. The robot body 1 has a stabilizing component at its bottom and a fire extinguishing component at its top. The fire monitor control module 12 precisely controls the operation of the fire extinguishing component.

[0021] The stabilizing component includes a base plate 13. The bottom of the robot body 1 is provided with an inner groove 14. The base plate 13 is fixed to the bottom between the inner walls on both sides of the inner groove 14 by bolts. The top inner wall of the inner groove 14 is fixed with a first motor 24 and a reducer 25 by bolts. The output shaft of the first motor 24 is keyed to the input shaft of the reducer 25. The output shaft of the reducer 25 is keyed to a first drive gear 15.

[0022] A threaded rod 17 is rotatably mounted on the top of the base plate 13 via an interlocking bearing. A first driven gear 16 is keyed to the top of the threaded rod 17. The first driven gear 16 meshes with the first driving gear 15. A sliding bracket 19 is threaded to the outer wall of the threaded rod 17. A drive motor 20 is bolted to multiple ends of the sliding bracket 19. A spiral drill bit 21 is bolted to the output end of the drive motor 20. The drive motor 20 drives the spiral drill bit 21 to rotate, which can drill into the mountain soil to form a deep fixing point. The other end of the sliding bracket 19 is welded with a mounting bracket 22, and the other end of the mounting bracket 22 is fixed with a ground grip plate 23 by bolts. The ground grip plate 23 is lowered to fit the ground and enhances friction through multi-point grip. Driven by the first motor 24 and reduced by the speed reducer 25, the first drive gear 15 rotates. Then, under the meshing action of the first drive gear 15 and the first driven gear 16, the threaded rod 17 rotates, causing the sliding bracket 19 to move downward along the guide shaft 18. This causes the auger drill bit 21 and the gripping nail plate 23 to move downward synchronously and contact the ground. Then, driven by the drive motor 20, the auger drill bit 21 rotates, causing it to drill into the soil. At the same time, the gripping nail plate 23 is driven into the ground, thereby enhancing the grip of the robot body 1 and improving the stability of the robot body 1 when parked.

[0023] Two guide shafts 18 are welded to the top of the base plate 13, and the sliding bracket 19 is slidably connected to the guide shafts 18.

[0024] A storage battery 26 is fixed inside the control box 8 by bolts, and the storage battery 26 provides independent power supply for the entire system.

[0025] The fire extinguishing assembly includes a booster pump 28, which is bolted to the top of the robot body 1. The outlet of the booster pump 28 is connected to a delivery pipe 27 via a flange. The other end of the delivery pipe 27 is connected to a rotary joint 31 via a flange. The other end of the rotary joint 31 is connected to a fire monitor 35 via a flange. The inlet pipe of the booster pump 28 is connected to a connecting pipe 29 via a flange. The other end of the connecting pipe 29 is connected to a connector 30 via a flange. The other end of the connector 30 is connected to one end of the fire hose 3 via a flange. Water from the rainwater collection tank 4 is drawn into the booster pump 28 via the fire hose 3 and the connecting pipe 29. After being pressurized, the water is delivered to the fire monitor 35 via the delivery pipe 27 and the rotary joint 31, and then sprayed out from the fire monitor 35 to extinguish the fire.

[0026] The top of the robot body 1 is fixed with a second motor 33 by bolts. The output end of the second motor 33 is keyed to a second drive gear 34. The outer circumference of the rotary joint 31 is fixed with a second driven gear 32 by bolts. The second drive gear 34 meshes with the second driven gear 32. Driven by the second motor 33, the second drive gear 34 rotates. Under the action of the meshing of the second drive gear 34 and the second driven gear 32, the rotary joint 31 and the fire monitor 35 swing up and down, thereby adjusting the angle of fire extinguishing.

[0027] The top of the robot body 1 is fixed with a protective cover 36 by bolts. The second motor 33, the second driving gear 34 and the second driven gear 32 are located inside the protective cover 36. The protective cover 36 protects the second motor 33, the second driving gear 34 and the second driven gear 32, and at the same time provides support for the rotation of the rotary joint 31.

[0028] The top of the robot body 1 is fixed with a bracket by bolts. The top of the bracket is fixed with an environmental monitoring camera 6 and a signal receiving antenna 7 by bolts. The camera collects information about the surrounding environment in real time as the robot moves, providing visual support for path planning. The signal receiving antenna 7 enhances the communication signal and ensures stable data interaction with the control center in the complex electromagnetic environment of the mountainous area. Two lights 37 are embedded in the front end of the robot body 1. The lights 37 provide illumination for operations at night or in low visibility environments, ensuring the accuracy of movement and firefighting.

[0029] The working principle of this embodiment is as follows: When in use, the fire monitoring camera 2 first monitors the mountain photovoltaic power station in real time. When a fire is detected, the location and scale of the fire are transmitted to the PLC controller 9 via the local area network. Then, the PLC controller 9 immediately starts the response program, plans the optimal path through the motion control module 10, and drives the tracked chassis 5 to move towards the fire area. At the same time, the lighting 37 and the environmental monitoring camera 6 are turned on to provide real-time feedback on the movement status. After the robot arrives at the fire area, the PLC controller 9 controls the first motor 24 to start. Driven by the first motor 24 and reduced by the reducer 25, the first drive gear 15 rotates. Then, under the action of the first drive gear 15 meshing with the first driven gear 16, the threaded rod 17 rotates, thereby causing the sliding bracket 19 to move downward along the guide shaft 18. This causes the auger drill bit 21 and the gripping nail plate 23 to move downward synchronously and contact the ground. At the same time, the PLC controller 9 controls the drive motor 20 to start. Driven by the drive motor 20, the auger drill bit 21 rotates, causing the auger drill bit 21 to drill into the soil. Meanwhile, the gripping nail plate 23 is driven into the ground, thereby enhancing the grip of the robot body 1 and improving the stability of the robot body 1 when parked. Then, the PLC controller 9 controls the start of the booster pump 28. The water in the rainwater collection tank 4 is drawn into the booster pump 28 through the fire hose 3 and connecting pipe 29. After being pressurized, the water is delivered to the fire monitor 35 through the delivery pipe 27 and rotary joint 31, and then sprayed out from the fire monitor 35 to extinguish the fire. At the same time, the environmental monitoring camera 6 captures and transmits the real-time fire situation to the PLC controller 9 for processing. Then, the PLC controller 9 controls the second motor 33 to run. Driven by the second motor 33, the second drive gear 34 rotates. Under the action of the second drive gear 34 and the second driven gear 32 meshing, the rotary joint 31 and the fire monitor 35 swing up and down, thereby adjusting the angle of fire extinguishing for precise fire extinguishing. After the fire is extinguished, the booster pump 28 and the fire monitor 35 are turned off. Then, the first motor 24 is controlled to move in the opposite direction by the PLC controller 9 to retract the auger drill bit 21 and the ground gripping nail plate 23. Finally, the robot body 1 returns to the standby area to complete the operation.
