Description

Technical Field

[0001] This application relates to the field of rotary fire extinguishing technology, and in particular to a rotary fire extinguishing device. Background Technology

[0002] Grassland and forest surface fires are characterized by rapid spread, dispersed fire points, rugged terrain, and a high rate of smoldering reignition. Current field firefighting methods mainly include manual battering, wind-powered fire extinguishers, and vehicle-mounted water-based spraying.

[0003] Manual firefighting is inefficient, labor-intensive, and carries significant risks in high-temperature, dense smoke environments, making it difficult to handle large-scale fires. Wind-powered fire extinguishers typically only extinguish surface flames and are ineffective against deeply accumulated combustion media and persistent fires; for example, a multi-stage jet-type wind-powered fire extinguisher (publication number CN102107052A). Vehicle-mounted water-based sprinkler systems are highly dependent on water supply and unsuitable for remote areas without or with scarce water resources; for example, a water sprinkler system that can be used as both a fire truck and a water truck (publication number CN221384991U). With technological advancements, to overcome the shortcomings of the above firefighting methods, mechanical rotary fire extinguishing equipment has emerged to address surface fires in grasslands and forests; for example, a grassland fire extinguishing vehicle (publication number CN116688398A).

[0004] However, in practical applications, the existing mechanical rotary fire extinguishing equipment lacks structural rigidity and is easily affected by torsional forces and lateral impact forces during high-speed rotary operation, causing the equipment to shake, shift, and overturn, affecting the reliability and safety of fire extinguishing. In addition, the equipment lacks a terrain-adaptive structure, and the fire extinguishing pressure is easily unevenly distributed on complex and undulating ground, resulting in incomplete fire extinguishing in low-lying areas and missed fire extinguishing in raised areas, thus creating fire extinguishing dead zones. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a rotary fire extinguishing device. The technical solution adopted by the present invention is as follows: A rotary fire extinguishing device, comprising: The support structure includes a main load-bearing column, a first reinforcing support column, and mounting arms.

The rotary beater structure includes a hydraulic motor, a rotary beater roller, and a refractory beater plate. The refractory beater plate is fixedly disposed on the outer circumferential surface of the rotary beater roller. The rotary beater roller is rotatably connected to a support structure, and one end of the rotary beater roller is fixedly connected to the output end of the hydraulic motor.

[0006] Furthermore, each of the mounting arms has a lifting arm with a hinged structure at its front end, and a mounting plate is fixedly connected to the other end of the lifting arm. The rotary roller is rotatably connected to the mounting plate, and the hydraulic motor is fixedly mounted on the outer end face of the mounting plate.

[0007] Furthermore, adaptive follower wheels are rotatably provided on the inner sides of both mounting plates, and the adaptive follower wheels are loosely fitted onto the shaft end of the rotary roller through bearings.

[0008] Furthermore, both sides of the rotary roller are provided with an electrically controlled take-up and release structure. The electrically controlled take-up and release structure includes a drive component, a take-up and release drum, a guide structure, a traction rope, and a lifting ring. The lifting ring is fixedly connected to the mounting plate. One end of the traction rope is tied to the lifting ring, and the other end of the traction rope passes through the guide structure and is connected to the take-up and release drum. The take-up and release drum is fixedly connected to the drive component, and the guide structure is fixedly connected to the support structure.

[0009] Furthermore, the driving component includes a drive motor and a first mounting base. The first mounting base is fixedly connected to the main load-bearing column, and the drive motor is fixedly installed inside the first mounting base. The output end of the drive motor is fixedly connected to the take-up and undo drum. A second mounting base is fixedly installed on one side of the first mounting base, and the take-up and undo drum is rotatably connected to the second mounting base.

[0010] Furthermore, the guide structure includes a first mounting frame, a second mounting frame, a first fixed pulley, and a second fixed pulley. The second fixed pulley is rotatably connected to the second mounting frame, and the first fixed pulley is rotatably connected to the first mounting frame. The first mounting frame is fixedly connected to the main load-bearing column, and the second mounting frame is fixedly connected to the mounting arm. The traction rope passes through the first fixed pulley and the second fixed pulley.

[0011] Furthermore, the electrically controlled retraction and extension structure also includes a tension adjustment assembly, which includes a fixed plate, a tension wheel, an adjusting screw, and a locking nut. The locking nut is connected to the adjusting screw via a threaded engagement. A third mounting bracket is fixedly mounted on the lower end face of the adjusting screw, and the third mounting bracket is rotatably connected to the tension wheel. The traction rope passes through the tension wheel. The adjusting screw is slidably connected to the fixed plate, and the fixed plate is fixedly connected to the upper end face of the mounting arm. A guide post is fixedly mounted on the upper end face of the fixed plate, and the adjusting screw is slidably connected to the guide post. The guide post has a guide hole, and the fixed plate has a mounting hole that communicates with the guide hole.

[0012] Furthermore, a support plate is fixedly provided on the upper end face of the mounting arm, the support plate has a first pin hole, and a hanging plate is fixedly provided on the outer end face of the mounting plate, the hanging plate has a second pin hole; the hanging plate and the support plate are connected by a pin shaft.

[0013] Furthermore, a safety protective cover is provided on the outside of the rotary roller, and the safety protective cover is fixedly connected to the mounting plate.

[0014] Furthermore, the main load-bearing column and the mounting arm are arranged perpendicularly, and the side end face of the main load-bearing column is fixedly connected to the lower end face of the mounting arm with a second reinforcing support column; front support bars are fixedly installed on the front end faces of the two mounting arms.

[0015] The beneficial effects of this invention are: By setting up a support structure consisting of a main load-bearing column, a first reinforced support column, and an installation arm, the first reinforced support column and the main load-bearing column form a triangular stable structure, which significantly improves the overall structural rigidity of the device, effectively offsets the torsional force and impact force during operation, enables the equipment to operate stably, and enhances its anti-overturning ability.

[0016] Several evenly distributed fire-resistant patting plates on the rotating roller rotate under the drive of a hydraulic motor.

[0017] By setting adaptive follow-up wheels, the device adapts to the undulating terrain of the fire extinguishing site and rolls close to the ground during fire extinguishing operations. It can automatically adjust the working gap between the rotating beater structure and the ground according to the terrain undulations, making the beating force applied to the ground by the fire-resistant beater plate more uniform, effectively avoiding the phenomenon of skipping beaters and fire leakage, achieving full fire extinguishing coverage, and expanding the device's adaptability to different terrains.

[0018] By setting independent electrically controlled retraction and extension structures on both sides of the rotary drum roller, the retraction and extension structures on both sides can control synchronous drive to lift and store the rotary drum structure and adaptive follower wheel, which has high lifting and lowering synchronization accuracy and good fault tolerance capability; effectively increasing the ground clearance of the equipment in non-fire extinguishing state, avoiding scratches and wear on the rotary drum structure during transportation, and enhancing protection, obstacle crossing ability and transportation convenience.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this invention. The specific implementation scheme of this invention is as follows: like Figures 1-4 As shown, a rotary fire extinguishing device includes a support structure and a rotary fire extinguishing structure. The support structure includes a main load-bearing column 1, a first reinforcing support column 2, and an mounting arm 3. The mounting arm 3 is fixedly installed on the upper surfaces of both sides of the main load-bearing column 1, and the first reinforcing support column 2 is fixedly connected to both ends of the main load-bearing column 1. The rotary fire extinguishing structure includes a hydraulic motor 4, a rotary fire extinguishing roller 5, and a fire-resistant striking plate 6. The fire-resistant striking plate 6 is fixedly installed on the outer circumferential surface of the rotary fire extinguishing roller 5, which is rotatably connected to the support structure. One end of the rotary fire extinguishing roller 5 is fixedly connected to the output end of the hydraulic motor 4. By setting up a support structure composed of the main load-bearing column 1, the first reinforcing support column 2, and the mounting arm 3, the first reinforcing support column 2 and the main load-bearing column 1 form a triangular stable structure, which significantly improves the overall structural rigidity of the device, effectively counteracts the torsional force and impact force during operation, ensures stable operation of the equipment, and enhances its anti-overturning ability. The plurality of fire-resistant striking plates 6 are arranged in a matrix on the outer circumferential surface of the rotary drum 5, forming an axial striking group along the axis of the rotary drum 5 and a circumferential striking group along the circumference of the rotary drum 5. The plurality of uniformly distributed fire-resistant striking plates 6 on the rotary drum 5 rotate under the drive of the hydraulic motor 4, and the striking plates generate a continuous and strong centrifugal striking force, which can penetrate the surface layer of the burning medium, completely extinguish surface open flames and deep smoldering fire points, eliminate fire extinguishing dead zones, and effectively reduce the reignition rate.

[0025] Preferably, the fire-resistant beater plate 6 is made of fatigue-resistant flexible fire-resistant board. The fatigue-resistant flexible fire-resistant board has excellent fatigue resistance properties such as high temperature resistance, flame retardancy, and resistance to repeated bending. It can beat the fire-resistant board under high-speed circulation for a long time, and is suitable for high-intensity continuous fire extinguishing operations in the field with strong operational stability.

[0026] It should be noted that the front end of each mounting arm 3 is equipped with a lifting arm 7 in a hinged structure, and the other end of the lifting arm 7 is fixedly connected to a mounting plate 8. The rotary drum roller 5 is rotatably connected to the mounting plate 8, and the hydraulic motor 4 is fixedly mounted on the outer end face of the mounting plate 8. This structure is mainly used to connect the rotary drum structure to the support structure.

[0027] It should be noted that adaptive follower wheels 9 are rotatably mounted on the inner sides of both mounting plates 8. The adaptive follower wheels 9 are loosely fitted onto the shaft end of the rotary drum roller 5 via bearings. The adaptive follower wheels 9 can rotate independently and freely relative to the rotary drum roller 5. Specifically, rolling bearings are installed between the inner ring of the hub of the adaptive follower wheel 9 and the journal of the rotary drum roller 5, so that their rotations do not interfere with each other.

[0028] By setting the adaptive follow-up wheel 9, it adapts to the undulating terrain of the fire extinguishing site and rolls close to the ground during fire extinguishing operations. It can automatically adjust the working gap between the rotating beater structure and the ground according to the terrain undulations, so that the beating force applied to the ground by the fire-resistant beater plate 6 is more uniform, effectively avoiding the phenomenon of skipping beater and fire leakage, achieving full fire extinguishing coverage, and expanding the device's adaptability to different terrains.

[0029] It should be noted that both sides of the rotary drum roller 5 are equipped with electrically controlled retraction and deployment structures 10. Each electrically controlled retraction and deployment structure 10 includes a drive component 11, a retraction and deployment drum 12, a guide structure 13, a traction rope 14, and a lifting ring 15. The lifting ring 15 is fixedly connected to the mounting plate 8. One end of the traction rope 14 is tied to the lifting ring 15, and the other end passes through the guide structure 13 and connects to the retraction and deployment drum 12. The retraction and deployment drum 12 is fixedly connected to the drive component 11, and the guide structure 13 is fixedly connected to the support structure. By providing independent electrically controlled retraction and deployment structures 10 on both sides of the rotary drum roller 5, the retraction and deployment structures on both sides can be controlled synchronously, enabling the rotary drum structure and the adaptive follower wheel 9 to be lifted and stored. This achieves high lifting synchronization accuracy and good fault tolerance; effectively increases the ground clearance of the equipment in non-firefighting conditions, avoids scratches and wear on the rotary drum structure during transportation, and enhances protection, obstacle crossing ability, and transportation convenience.

[0030] Furthermore, the driving component 11 includes a drive motor 110 and a first mounting base 111. The first mounting base 111 is fixedly connected to the main load-bearing column 1, and the drive motor 110 is fixedly installed inside the first mounting base 111. The output end of the drive motor 110 is fixedly connected to the take-up and unwinding drum 12. A second mounting base 121 is fixedly installed on one side of the first mounting base 111, and the take-up and unwinding drum 12 is rotatably connected to the second mounting base 121. The first mounting base 111 is mainly used to fix the drive motor 110, and the second mounting base 121 is mainly used to fix the take-up and unwinding drum 12, which is used to wind the traction rope 14.

[0031] Preferably, the drive motor 110 is a servo motor, and the drive motors 110 of the electrically controlled retraction and extension structures 10 on both sides of the rotary drum roller 5 can be synchronously controlled by an external control system, thereby realizing the horizontal lifting and lowering of the rotary drum structure and horizontal operation. In addition, a counterweight is fixedly installed on the mounting plate 8 on the other side of the rotary drum structure to keep the lifting load on both sides of the rotary drum structure balanced, thereby overcoming the lifting deviation caused by the asymmetry of the load on both sides.

[0032] Furthermore, the guide structure 13 includes a first mounting frame 130, a second mounting frame 131, a first fixed pulley 132, and a second fixed pulley 133. The second fixed pulley 133 is rotatably connected to the second mounting frame 131, and the first fixed pulley 132 is rotatably connected to the first mounting frame 130. The first mounting frame 130 is fixedly connected to the main load-bearing column 1, and the second mounting frame 131 is fixedly connected to the mounting arm 3. The traction rope 14 passes through the first fixed pulley 132 and the second fixed pulley 133. The first fixed pulley 132 and the second fixed pulley 133 constrain and guide the winding and unwinding path of the traction rope 14, achieving smoother power transmission. Furthermore, the two sets of fixed pulleys prevent the traction rope 14 from deviating and causing it to disengage from the groove.

[0033] It should be noted that the electrically controlled retraction structure 10 also includes a tension adjustment assembly, which includes a fixed plate 16, a tension wheel 17, an adjusting screw 18, and a locking nut 19. The locking nut 19 is threadedly connected to the adjusting screw 18. A third mounting bracket 20 is fixedly mounted on the lower end face of the adjusting screw 18. The third mounting bracket 20 is rotatably connected to the tension wheel 17. The traction rope 14 passes through the tension wheel 17. The adjusting screw 18 is slidably connected to the fixed plate 16, and the fixed plate 16 is fixedly connected to the upper end face of the mounting arm 3. The tension adjustment structure is mainly used to adjust the preload of the traction rope 14 to prevent the traction rope 14 from becoming slack or vibrating during operation, thus ensuring the stability of the operation.

[0034] A guide post 21 is fixedly mounted on the upper surface of the fixing plate 16. The adjusting screw 18 is slidably connected to the guide post 21. The guide post 21 has a guide hole 22, and the fixing plate 16 has a mounting hole 23, which communicates with the guide hole 22. The guide post 21 provides guidance for the adjusting screw 18, facilitating its lifting and lowering movement, thereby adjusting the tension of the tension wheel 17 on the traction rope 14.

[0035] Specifically, during the tension adjustment process, the locking nut 19 is loosened to release the circumferential lock on the adjusting screw 18, and then the adjusting screw 18 is controlled to move up and down along the guide post 21. The tension wheel 17 moves up and down synchronously with the adjusting screw 18, thereby linearly changing the pushing depth of the tension wheel 17 on the traction rope 14 to achieve tension adjustment. After reaching the preset tension, the locking nut 19 is tightened to lock the position of the adjusting screw 18, ensuring the tension of the tension wheel 17 on the traction rope 14.

[0036] It should be noted that a support plate 24 is fixedly mounted on the upper end face of the mounting arm 3, and the support plate 24 has a first pin hole 25. A hanging plate 26 is fixedly mounted on the outer end face of the mounting plate 8, and the hanging plate 26 has a second pin hole 27. The hanging plate 26 and the support plate 24 are connected by a pin. This structure is mainly used to fix the position of the lifted adaptive follower wheel 9 and the rotating drum structure, avoiding scratches and wear on the rotating drum structure during transportation, and enhancing protection, obstacle crossing ability, and transportation convenience.

[0037] Specifically, when the rotary drum structure is lifted and stored, the drive motor 110 starts and rotates forward, driving the take-up and undo drum 12 to rotate to tighten the traction rope 14. During the retrieval process, the traction rope 14 transmits tension through the guide structure 13. The retrieval of the traction rope 14 will drive the mounting plate 8 to perform an upward movement as a whole. The rise of the mounting plate 8 will drive one end of the lifting arm 7 to rise, and the other end of the lifting arm 7 will rotate clockwise around the connection point with the first crossbeam, thereby driving the follower wheel and the rotary drum structure to move upward. The mounting plate 26 moves upward synchronously with the mounting plate 8 until the second pin hole 27 of the mounting plate 26 is aligned with the first pin hole 25 of the support plate 24. Then, a pin is used to pass through the first pin hole 25 and the second pin hole 27 to complete the locking connection between the mounting plate 26 and the support plate 24, thereby fixing the rotary drum structure to the frame. During the locking process, the drive motor 110 stops running.

[0038] When the mounting plate 26 approaches the support plate 24, the rotation angle of the drive motor 110 is finely adjusted by the external control system to adjust the height of the mounting plate 26 so that the second pin hole 27 and the first pin hole 25 are gradually aligned, and then the pin shaft is inserted to complete the locking.

[0039] Furthermore, a safety cover 28 is provided on the outer side of the rotary drum 5, and the safety cover 28 is fixedly connected to the mounting plate 8. The safety cover 28 is a long strip-shaped shell made of thickened heat-resistant stainless steel, bent and welded in one piece. The cross-section of the safety cover 28 is C-shaped, and both ends of the safety cover 28 are fixed to the mounting plate 8 by bolts. The safety cover 28 covers the rotary drum 5 and the rotary drum operation area of ​​the fire-resistant striking plate 6 fixedly installed on its outer circumference in a semi-enclosed manner above and to the side. During the rotary drum operation, the safety cover 28 can intercept high-temperature sparks and hot residue splashed during the operation, avoiding secondary fires caused by them, and can also block the outward spread of high temperature and toxic fumes.

[0040] The lowest point of the lower edge of the side of the safety cover 28 is higher than the lowest point of the wheel flange under the maximum allowable terrain undulation of the adaptive follower wheel 9, so as to ensure that the safety cover 28 reduces interference with ground protrusions when the device is operating on uneven ground.

[0041] Preferably, the safety cover 28 has an opening at the position corresponding to the rotary beater output to ensure that the refractory beater plate 6 can perform the beater operation normally while maintaining effective restraint of splashes and smoke. The left and right boundaries of the opening of the safety cover 28 are outside the axial beater area of ​​the refractory beater plate 6, and the lower boundary of the opening is always higher than the grounding point of the adaptive follower wheel 9.

[0042] Furthermore, the main load-bearing column 1 is arranged perpendicularly to the mounting arm 3. A second reinforcing support column 29 is fixedly connected to the side end face of the main load-bearing column 1 and the lower end face of the mounting arm 3. The second reinforcing support column 29, the main load-bearing column 1, and the mounting arm 3 together form a triangular support frame. A front support bar 30 is fixedly installed on the front end face of the two mounting arms 3. This significantly enhances the bending and torsional stiffness at the root of the mounting arm 3. At the same time, the front support bar 30 connects the front ends of the two mounting arms 3 into one unit, greatly enhancing the connection stiffness and integrity of the two mounting arms 3 at the front end, further reducing vibration and deformation caused by operation. The synergistic effect of both significantly improves the stability of the device during continuous rotary tapping operations.

[0043] The working principle and process of this invention are as follows: The process of lowering the rotating flap structure in preparation for firefighting: First, pull the pin out of the first pin hole 25 and the second pin hole 27 to release the fixing between the hanging plate 26 and the support plate 24. Then, start the drive motor 110, which runs in reverse to drive the take-up and unwind drum 12 to rotate and release the traction rope 14. The traction rope 14 is released outward through the guide path formed by the first fixed pulley 132, the tensioning pulley 17 and the second fixed pulley 133, providing rope length margin for the mounting plate 8 and the external beating structure. The traction rope 14 is released through the first fixed pulley 132, the tensioning pulley 17 and the second fixed pulley 133. Under the gravity of the adaptive follower wheel 9 and the rotating beater structure, the above components rotate counterclockwise around the hinge point of the lifting arm 7 and the mounting arm 3, applying tension to the traction rope 14 in the released state, so that the traction rope 14 is tensioned and continuously released under the constraint of the guide structure 13. During this process, the mounting plate 8 drives the adaptive follower wheel 9 and the rotating beater structure to perform a downward movement until the adaptive follower wheel 9 is in contact with the working surface.

[0044] Then start the hydraulic motor 4, which drives the rotary drum roller 5 to rotate. The rotation of the rotary drum roller 5 will drive the fire-resistant beater plate 6 to rotate and beat the working surface in a cyclical manner, thereby extinguishing the fire.

[0045] The process of lifting and storing the equipment is required to complete the firefighting operation. The drive motor 110 is restarted, and it rotates in the forward direction, causing the take-up and unwind drum 12 to rotate in the reverse direction to tighten the traction rope 14. During the retrieval process, the traction rope 14 transmits tightening force through the first fixed pulley 132, the tensioning pulley 17, and the second fixed pulley 133. The traction rope 14 is tightened to the take-up and unwind drum 12 through the second fixed pulley 133, the tensioning pulley 17, and the first fixed pulley 132. The traction rope 14 applies an upward pulling force to the lifting ring 15, driving the mounting plate 8 to drive the rotating mechanism to perform an upward movement. The rise of the mounting plate 8 causes one end of the lifting arm 7 to rise, and the other end of the lifting arm 7 rotates clockwise around the hinge point with the mounting arm 3, thereby driving the adaptive follower wheel 9 and the rotating mechanism to move upward. The mounting plate 26 moves upward synchronously with the mounting plate 8. As the mounting plate 8 continues to rise, when the mounting plate 26 rises to the point where its second pin hole 27 is coaxially aligned with the first pin hole 25 of the support plate 24, the drive motor 110 stops running. Then, a pin is used to pass through the first pin hole 25 and the second pin hole 27 to lock the mounting plate 26 and the support plate 24 together, thereby fixing the rotating mechanism onto the support structure.
