Description

Technical Field

[0001] This utility model relates to the technical field of sprinkler devices for firefighting robots, and more specifically, it relates to a sprinkler device for firefighting robots. Background Technology

[0002] Sprinkler systems for firefighting robots, as a crucial component of modern firefighting systems, play a vital role in fire rescue and firefighting operations. However, traditional firefighting robot sprinkler systems have significant technical limitations: the flow rate of firefighting water is typically fixed. This fixed flow rate design cannot adjust the flow rate according to actual usage needs and different fire conditions. In actual firefighting operations, different types of fires (such as oil fires, electrical fires, and solid combustible material fires) require different water flow impact forces and spray patterns, and the fixed flow rate design makes the sprinkler system difficult to adapt to complex and changing conditions. In fire environments, for example, excessive water flow may cause unnecessary waste of water resources and property damage in the early stages of small-scale fires; while insufficient flow rate may lead to low fire extinguishing efficiency and delay the best rescue opportunity when facing large and fierce fires. In addition, a fixed flow rate cannot achieve optimal range control in fire extinguishing operations at different distances. When spraying at close range, the impact force may be too great and cause secondary injuries, while when spraying at long distance, the flow rate may be insufficient to reach the core of the fire source. This lack of flexibility in design seriously restricts the application effect of firefighting robots in complex fire environments, resulting in adverse effects such as low fire extinguishing efficiency, waste of resources and safety hazards.

[0003] Secondly, while some equipment achieves flexible adjustment of the fire water delivery speed through the cooperation of certain components, allowing operators to adjust the water flow rate to a certain extent according to the needs of the fire, its simple structure and insufficient stability make it prone to changes in the adjusted structure due to external forces and internal pipeline pressure impacts during long-term use. Especially when the fire robot moves at high speed or encounters obstacles, mechanical vibrations will be transmitted to the adjustment device, causing internal parts to loosen or become misaligned. At the same time, when the water flow is suddenly started or stopped, the resulting "water hammer effect" will impact the pipeline system and adjustment device, further exacerbating the instability of the adjustment structure. The combined effect of these factors leads to unpredictable fluctuations in the adjusted delivery speed, making the water jet unstable and the spray angle and distance difficult to control precisely, seriously affecting the fire extinguishing effect. It may even cause equipment damage or personnel injury due to sudden high-pressure water flow impacts, posing a serious safety hazard to fire rescue operations. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a spraying device for fire-fighting robots to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a sprinkler device for a fire-fighting robot, comprising a robot assembly, a detachable delivery pump at the top of the robot assembly, a transmission pipe connected to the output end of the delivery pump, a control sleeve and a connecting pipe on one side of the transmission pipe, the two ends of the control sleeve being rotatably connected to the transmission pipe and the connecting pipe respectively, a conversion plate rotatably mounted on the outside of the connecting pipe, a through hole and a guide groove on the conversion plate, the through hole being located at one end of the guide groove, a sliding sleeve sleeved on the outside of the connecting pipe, a control rod connected to one side of the sliding sleeve, a fixed plate fixedly mounted on the control rod, an adjustment plate movably mounted inside the control sleeve, a running shaft and a rotating shaft rotatably mounted on the adjustment plate, multiple placement grooves on the outside of the connecting pipe, a support frame fixedly mounted on one side of the control sleeve, a connecting rod slidably mounted in the support frame, a drive plate fixedly connected to one end of the connecting rod, a traction spring movably sleeved on the outside of the connecting rod, the other end of the connecting rod being inserted into the placement groove, the two ends of the traction spring being connected to the drive plate and the support frame respectively, and a guide rail groove on one side of the transmission pipe.

[0006] The present invention is further configured such that a water storage tank is detachably provided on the robot component, an input pipe is connected to the input end of the delivery pump, and the other end of the input pipe extends into the bottom of the water storage tank.

[0007] The present invention is further configured such that a spray head is detachably provided at the top of the robot component, and the output end of the connecting pipe is detachably connected to the input end of the spray head.

[0008] The present invention is further configured such that the adjustment plate has multiple flow holes.

[0009] The present invention is further configured such that the fixing plate is provided in two places, and the structure design of the double fixing plate forms a more reliable locking system for the control mechanism.

[0010] The present invention is further configured such that one end of the running shaft slides in the guide groove, and one end of the rotating shaft is rotatably connected to the inner wall of the regulating sleeve. Through the sliding fit of the running shaft in the guide groove and the rotatable connection between the rotating shaft and the inner wall of the regulating sleeve, a dual support and guiding system for the adjusting plate is formed, ensuring the smooth movement of the adjusting plate during the flow rate adjustment process.

[0011] The present invention is further configured such that a return spring is movably sleeved on the outside of the control lever, one end of the return spring is connected to the sliding sleeve, and the other end of the return spring is connected to the conversion plate in contact. Through the elastic action of the return spring, the automatic reset function of the sliding sleeve and the control lever is realized.

[0012] The present invention is further configured such that one end of the connecting rod and the edge of the inner wall of the mounting groove are both designed with rounded corners. The rounded corner design of the end of the connecting rod and the edge of the inner wall of the mounting groove significantly reduces the frictional resistance and jamming risk when the connecting rod is inserted into and pulled out of the mounting groove, making the locking and unlocking operations smoother and more reliable.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a sprinkler device for fire-fighting robots, which has the following beneficial effects: 1. By incorporating components such as a transmission pipe, regulating sleeve, connecting pipe, conversion plate, through hole, guide groove, sliding sleeve, control lever, fixed plate, adjustment plate, running shaft, rotating shaft, mounting groove, support frame, linkage rod, drive plate, traction spring, and guide rail groove, a system capable of flexibly adjusting the water flow rate is formed. This solves the technical problem of fixed and unadjustable fire water delivery speed in traditional fire robot sprinkler systems. Users can rotate the regulating sleeve to move the flow hole on the adjustment plate. This movement of the flow hole, in conjunction with the movement of the adjustment plate, changes the internal flow area of ​​the transmission pipe, thereby achieving flexible adjustment of the fire water delivery speed. This design enables the fire robot to adjust the flow rate according to different fire conditions. The water flow impact force and spraying method can be adjusted according to the actual needs of different types of fires (such as oil fires, electrical fires, and solid combustible fires). For small-scale fires in the early stages, a lower flow velocity can be selected to avoid water waste and property damage. When facing large and intense fires, the flow velocity can be increased to improve fire extinguishing efficiency. At the same time, range control can be achieved in fire extinguishing operations at different distances. When spraying at close range, the flow velocity can be reduced to avoid excessive impact force and secondary damage. When spraying at long distance, the flow velocity can be increased to ensure that the water flow can reach the core of the fire source. This greatly improves the adaptability and fire extinguishing efficiency of firefighting robots in complex fire scene environments and solves the adverse effects of low fire extinguishing efficiency, resource waste and safety hazards caused by traditional fixed flow velocity design.

[0014] 2. Through the synergistic effect of multiple locking mechanisms, the stability and reliability of the flow rate adjustment structure are significantly improved. This design employs a complete multi-locking system consisting of components such as a return spring, control lever, fixed plate, conversion plate, through hole, guide groove, sliding sleeve, support frame, connecting rod, traction spring, drive plate, and mounting groove. After the flow rate adjustment is completed, the return spring pushes the sliding sleeve to reset, causing the control lever and fixed plate to return to their original positions. The conversion plate rotates in the opposite direction so that the through hole and guide groove do not correspond to the control lever, thereby allowing the control lever to work with the fixed plate to limit the sliding sleeve to one side of the conversion plate, preventing accidental movement of the sliding sleeve. At the same time, the inner wall of the sliding sleeve limits the outer wall of the drive plate, preventing the drive plate and connecting rod from sliding outwards, while the connecting rod inserts into the mounting groove to achieve support. The locking mechanism ensures that the support frame and control sleeve will not rotate unexpectedly. This multi-nested locking structure effectively overcomes the defects of traditional simple adjustment devices that are prone to structural changes due to external forces and internal pipeline pressure during long-term use. Even when the fire robot moves or encounters obstacles and experiences mechanical vibrations, or when the water flow is suddenly started or stopped and subjected to the "water hammer effect," the locking system can still maintain the stability of the adjustment structure. This ensures that the adjusted delivery flow rate will not fluctuate unpredictably, keeping the water column stable and the spray angle and distance precisely controllable. This significantly improves the fire extinguishing effect and avoids equipment damage or personnel injury caused by sudden high-pressure water flow impacts, providing a higher level of safety for fire rescue operations.

[0020] Please see Figures 1-5 A sprinkler system for a fire-fighting robot includes a robot assembly 1. A delivery pump 2 is detachably mounted on the top of the robot assembly 1. A transmission pipe 3 is connected to the output end of the delivery pump 2. A regulating sleeve 4 and a connecting pipe 5 are mounted on one side of the transmission pipe 3. The two ends of the regulating sleeve 4 are rotatably connected to the transmission pipe 3 and the connecting pipe 5, respectively. A conversion plate 6 is rotatably mounted on the outside of the connecting pipe 5. The conversion plate 6 has a through hole 7 and a guide groove 8. The through hole 7 is located at one end of the guide groove 8. A sliding sleeve 9 is fitted onto the outside of the connecting pipe 5. A control lever 10 is connected to one side of the sliding sleeve 9. A device is fixedly mounted on the control lever 10. There is a fixed plate 11, and an adjustment plate 12 is movably provided inside the control sleeve 4. The adjustment plate 12 is rotatably mounted with a running shaft 13 and a rotating shaft 14. Multiple placement slots 15 are opened on the outside of the connecting pipe 5. A support frame 16 is fixedly provided on one side of the control sleeve 4. A connecting rod 17 is slidably provided in the support frame 16. A drive plate 18 is fixedly connected to one end of the connecting rod 17. A traction spring 19 is movably sleeved on the outside of the connecting rod 17. The other end of the connecting rod 17 is inserted into the placement slot 15. The two ends of the traction spring 19 are respectively connected to the drive plate 18 and the support frame 16. A guide rail groove 20 is opened on one side of the transmission pipe 3.

[0021] The robot component 1 is detachably equipped with a water storage tank 21, and the input end of the delivery pump 2 is connected to an input pipe 22, with the other end of the input pipe 22 extending into the bottom of the water storage tank 21.

[0022] The top of the robot component 1 is detachably equipped with a spray head 23, and the output end of the connecting pipe 5 is detachably connected to the input end of the spray head 23. In this embodiment, when the device is needed, first ensure that the water storage tank 21 is full of fire-fighting water, then drive the robot component 1 to move to a suitable location, then turn on the delivery pump 2 set at the top of the robot component 1, the delivery pump 2 draws out the fire-fighting water stored in the water storage tank 21 through the input pipe 22 connected to the input end, and then delivers the drawn fire-fighting water to the connecting pipe 5 through the transmission pipe 3 connected to the output end of the delivery pump 2, and finally sprays it out through the sprinkler head 23.

[0023] Please see Figures 3-5 As a further implementation of the overall equipment: the adjustment plate 12 is provided with multiple flow holes 24.

[0024] There are two fixing plates 11.

[0025] One end of the running shaft 13 slides in the guide rail groove 20, and one end of the rotating shaft 14 is rotatably connected to the inner wall of the regulating sleeve 4.

[0026] A return spring 25 is movably sleeved on the outside of the control lever 10. One end of the return spring 25 is connected to the sliding sleeve 9, and the other end of the return spring 25 is connected to the conversion plate 6 in contact.

[0027] Both the connecting rod 17 and the inner edge of the mounting groove 15 adopt a rounded corner design.

[0028] More specifically, when it is necessary to adjust the flow rate of gas and liquid, firstly, rotate the conversion plate 6, causing the through hole 7 and guide groove 8 to rotate in the forward direction. When the through hole 7 rotates to the position corresponding to the control lever 10, it pushes the sliding sleeve 9. The sliding sleeve 9 will cause one side of the control lever 10 and the fixing plate 11 to gradually slide into the through hole 7. The sliding sleeve 9 will cooperate with the conversion plate 6 to compress the return spring 25. When the return spring 25 is compressed to its limit, the fixing plate 11 set in the middle of the control lever 10 just passes through the through hole 7 and moves to the other side of the conversion plate 6. Then, rotate the conversion plate 6 in the reverse direction, causing the through hole 7 and guide groove 8 to rotate in the reverse direction, so that the control lever 10 enters the guide groove 8. When the control lever 10 When the outer wall contacts one end of the inner wall of the guide groove 8, the rotation of the conversion plate 6 stops. At this time, the control lever 10, in conjunction with the middle conversion plate 6, limits the sliding sleeve 9 to one side of the conversion plate 6, so that the sliding sleeve 9 no longer limits the outer wall of the drive plate 18. Then, the control sleeve 4 is rotated in the forward direction. The control sleeve 4 will drive the support frame 16 on one side to rotate in the forward direction. Then, the support frame 16 will drive the connecting rod 17, the traction spring 19, and the drive plate 18 to rotate in the forward direction. Then, the inner wall of the placement groove 15 presses against one end of the connecting rod 17. Due to the rounded corner structure design of the inner wall edge of the placement groove 15 and one end of the connecting rod 17, one end of the connecting rod 17 slides out of the placement groove 15, and the other end of the connecting rod 17 drives the traction spring 19 to stretch outward through the drive plate 18. At the same time, the control sleeve 4 rotates through the rotating shaft. 14 drives the inner adjusting plate 12 to move, causing the adjusting plate 12 to drive the running shaft 13 on the other side to spread outward along the guide rail groove 20, causing the adjusting plate 12 to spread outward and drive the flow hole 24 to move. The movement of the flow hole 24, in conjunction with the diffusion movement of the adjusting plate 12, changes the internal flow area of ​​the transmission pipe 3, thereby changing the fluid flow rate. When the appropriate conveying flow rate is adjusted, the rotation of the regulating sleeve 4 is stopped, and the support frame 16 drives the connecting rod 17 and other components to rotate to the position corresponding to the corresponding placement groove 15. Then, the traction spring 19 resets and pulls the drive plate 18. The drive plate 18 drives the connecting rod 17 to slide inward, so that one end of the connecting rod 17 is inserted into the corresponding placement groove 15, and then... Rotating the conversion plate 6 in the forward direction will cause the through hole 7 and guide groove 8 to rotate in the forward direction again. When the through hole 7 rotates to a position concentric with the fixed plate 11, the return spring 25 pushes the sliding sleeve 9 to slide and reset. Then, the sliding sleeve 9 drives the two fixed plates 11 to slide and reset via the control lever 10 on one side. After the return spring 25 has fully reset, the fixed plate 11 at the top of the control lever 10 moves back to the original side of the conversion plate 6. Then, rotating the conversion plate 6 in the reverse direction will reset it, causing the conversion plate 6 to rotate and reset the through hole 7 and guide groove 8 to a position that does not correspond to the control lever 10 and the fixed plate 11. Then, the control lever 10, together with the top fixed plate 11, limits and supports the sliding sleeve 9 to one side of the conversion plate 6, so that the sliding sleeve 9 will not slide easily.Then, the inner wall of the sliding sleeve 9 limits the outer wall of the drive plate 18, preventing the drive plate 18 and the connecting rod 17 from sliding outward. The connecting rod 17 then cooperates with the mounting groove 15 to lock the support frame 16, preventing the support frame 16 and the regulating sleeve 4 from rotating unexpectedly. This ensures the structural stability after the flow rate adjustment and guarantees stable fluid delivery.

[0029] In summary, when the equipment is in use or running: First, ensure that the water storage tank 21 is full of fire-fighting water. Then, drive the robot component 1 to a suitable location. Then, turn on the delivery pump 2 set at the top of the robot component 1. The delivery pump 2 draws out the fire-fighting water stored in the water storage tank 21 through the input pipe 22 connected to the input end. Then, the drawn fire-fighting water is delivered to the connecting pipe 5 through the transmission pipe 3 connected to the output end of the delivery pump 2. Finally, it is sprayed out through the sprinkler head 23.

[0030] When the flow rate of gas and liquid needs to be adjusted, first rotate the conversion plate 6, causing the through hole 7 and guide groove 8 to rotate in the forward direction. When the through hole 7 rotates to the position corresponding to the control lever 10, it pushes the sliding sleeve 9. The sliding sleeve 9 will cause one side of the control lever 10 and the fixing plate 11 to gradually slide into the through hole 7. The sliding sleeve 9 will cooperate with the conversion plate 6 to compress the return spring 25. When the return spring 25 is compressed to its limit, the fixing plate 11 set in the middle of the control lever 10 just passes through the through hole 7 and moves to the other side of the conversion plate 6. Then, rotate the conversion plate 6 in the reverse direction, causing the through hole 7 and guide groove 8 to rotate in the reverse direction, so that the control lever 10 enters the guide groove 8. When the outer wall of the control lever 10 is in contact with the guide groove 8, the control lever 10 enters the guide groove 8. When the sliding sleeve 9 contacts one end of the inner wall of the groove 8, the rotation of the conversion plate 6 stops. At this time, the control lever 10, in conjunction with the middle conversion plate 6, limits the sliding sleeve 9 to one side of the conversion plate 6, so that the sliding sleeve 9 no longer limits the outer wall of the drive plate 18. Then, the control sleeve 4 is rotated in the forward direction. The control sleeve 4 will drive the support frame 16 on one side to rotate in the forward direction. Then, the support frame 16 will drive the connecting rod 17, the traction spring 19, and the drive plate 18 to rotate in the forward direction. Then, the inner wall of the placement groove 15 presses against one end of the connecting rod 17. Due to the rounded corner structure design of the inner wall edge of the placement groove 15 and one end of the connecting rod 17, one end of the connecting rod 17 slides out of the placement groove 15, and the other end of the connecting rod 17 drives the traction spring 19 to stretch outward through the drive plate 18. At the same time, the control sleeve 4 drives the traction spring 19 to stretch outward through the rotating shaft 14. The inner adjusting plate 12 moves, causing the adjusting plate 12 to drive the running shaft 13 on the other side to spread outward along the guide rail groove 20. This outward movement of the adjusting plate 12 causes the flow hole 24 to move. The movement of the flow hole 24, in conjunction with the diffusion movement of the adjusting plate 12, changes the internal flow area of ​​the transmission pipe 3, thereby changing the fluid flow rate. Once a suitable conveying flow rate is achieved, the rotating control sleeve 4 stops, and the support frame 16 drives the connecting rod 17 and other components to rotate to the position corresponding to the placement groove 15. Then, the traction spring 19 resets and pulls the drive plate 18. The drive plate 18 drives the connecting rod 17 to slide inward, so that one end of the connecting rod 17 is inserted into the corresponding placement groove 15. Then, it moves forward again. Rotating the conversion plate 6 will cause the through hole 7 and guide groove 8 to rotate forward again. When the through hole 7 rotates to a position concentric with the fixed plate 11, the return spring 25 pushes the sliding sleeve 9 to slide and reset. Then, the sliding sleeve 9 drives the two fixed plates 11 to slide and reset via the control lever 10 on one side. After the return spring 25 has fully reset, the fixed plate 11 at the top of the control lever 10 moves back to its original side of the conversion plate 6. Then, the conversion plate 6 is rotated in the opposite direction to reset, causing the conversion plate 6 to drive the through hole 7 and guide groove 8 to rotate and reset to a position that does not correspond to the control lever 10 and the fixed plate 11. Then, the control lever 10, together with the top fixed plate 11, limits and supports the sliding sleeve 9 to one side of the conversion plate 6, so that the sliding sleeve 9 will not slide easily.Then, the inner wall of the sliding sleeve 9 limits the outer wall of the drive plate 18, preventing the drive plate 18 and the connecting rod 17 from sliding outward. The connecting rod 17 then cooperates with the mounting groove 15 to lock the support frame 16, preventing the support frame 16 and the regulating sleeve 4 from rotating unexpectedly. This ensures the structural stability after the flow rate adjustment and guarantees stable fluid delivery.
