Abstract
Description
Technical Field
[0001] This utility model relates to the field of single-fiber measuring devices, and more specifically, to a fire extinguishing device that automatically retracts fire hoses. Background Technology
[0002] As a type of special-purpose robot, firefighting robots are playing an increasingly important role in firefighting and rescue operations. Currently, firefighting robots are used in conjunction with firefighters for fire rescue operations. These robots are often equipped with firefighting equipment, such as fire hoses, which are connected to the fire hoses during actual use.
[0003] Patent CN119345645A discloses an IoT-based intelligent firefighting robot, including a vehicle body and wheels. A ring-shaped storage cylinder is rotatably mounted at the rear of the vehicle body, with a water pipe wound around it. One end of the water pipe passes through the ring-shaped storage cylinder and connects to a water inlet pipe via a rotary joint; the other end extends to the outside of the ring-shaped storage cylinder and connects to a water source. A synchronous linkage mechanism is provided between the wheels and the ring-shaped storage cylinder. This mechanism includes a linkage rod, a linkage gear, and a connecting gear rotatably mounted on the vehicle body. The outer circumference of the ring-shaped storage cylinder has ring teeth. One side of the connecting gear meshes with the ring teeth, and the other side meshes with the linkage gear. The linkage rod is rotatably mounted on one side of the vehicle body, and a drive component is mounted on the rotating shaft to drive the linkage rod. During firefighting operations, the firefighting robot of this invention can synchronously retract and extend the water pipe at the rear of the vehicle body, avoiding interference with the robot's movement path.

Detailed Implementation
[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0031] like Figures 1-8 As shown, the embodiment provides an automatic fire hose retrieval device, including a frame 1 and an automatic cleaning and retrieval component mounted on the frame 1. The automatic cleaning and retrieval component includes a first turntable assembly 2, a second turntable assembly 4, and nozzles 3. Two first turntable assemblies 2 are respectively disposed on both sides of the second turntable assembly 4, and a nozzle 3 is disposed above each first turntable assembly 2. The first turntable assembly 2 includes a first turntable 21, a first clamping rod 22, a first cylinder 23, a second cylinder 24, and a first motor 27. The first turntable 21 has... A first slot 28 is provided. A first cylinder 23 is installed on the back of a first turntable 21. A second cylinder 24 is installed on the back of a first turntable 21. The free end of the first cylinder 23 is connected to a first fixing frame 25. The first fixing frame 25 passes through the first slot 28 and is connected to a first clamping rod 22. The free end of the second cylinder 24 is connected to a second fixing frame 26. The second fixing frame 26 passes through the first slot 28 and is connected to another first clamping rod 22. A first motor 27 is fixed on the frame 1. The drive end of the first motor 27 is fixedly connected to the first turntable 21.
[0032] After the fire is extinguished, the hose is disconnected from the water pipe. In one of the first rotary assembly 2, the first cylinder 23 retracts, causing one first clamping rod 22 to move downwards. The second cylinder 24 drives the other first clamping rod 22 upwards, bringing the two clamping rods 22 closer together to clamp the hose. The other rotary assembly operates similarly, but in this assembly, the first clamping rod 22 only needs to touch the surface of the hose and does not clamp it. The surface of the clamping rods serves to clean the hose as it slides across.
[0033] Next, the first turntable assembly 2, which clamps the water hose, begins to rotate clockwise under the drive of the first motor 27, winding the water hose around the two first clamping rods 22. Simultaneously, the nozzles 3 on the two first turntable assemblies 2 spray water downwards. Since the two first clamping rods 22 in the other first turntable assembly 2 only touch the water hose without clamping it, the water hose slides over them, allowing the first clamping rods 22 to clean the surface of the water hose and scrape away the dirt adhering to it. This continues until the end of the water hose is cleaned, at which point the rotation stops, completing the cleaning process. Then, the first clamping rods 22, which were initially only touching the water hose, move closer together to clamp the end of the water hose. Simultaneously, the first turntable assembly 2 containing these first clamping rods 22 begins to rotate counterclockwise on the drive belt of the first motor 27, winding the water hose from the other first turntable assembly 2 onto its own first clamping rod 22, until both first turntable assemblies 2 have the same amount of water hose wound on them. At this time, the second turntable assembly 4, located between the two first turntable assemblies 2, clamps the water hose and rolls the water hoses of the first turntable assemblies 2 on both sides onto itself, completing the overall cleaning and winding of the water hose.
[0034] Furthermore, the second turntable assembly 4 includes a second turntable 41, a second clamping rod 42, a third cylinder 45, a fourth cylinder 46, a fifth cylinder 44, a second motor 49, and a first fixing plate 43; the second turntable 41 has a second slot 40, the first fixing plate 43 is disposed on the back of the second turntable 41, the third cylinder 45, the fourth cylinder 46 and the two fifth cylinders 44 are all fixed on the first fixing plate 43, the free end of the third cylinder 45 is connected to a third fixing bracket 47, the third fixing bracket 47 passes through the second slot 40 and is fixedly connected to a second clamping rod 42, the free end of the fourth cylinder 46 is connected to a fourth fixing bracket 48, the fourth fixing bracket 48 passes through the second slot 40 and is fixedly connected to another second clamping rod 42, the free ends of the two fifth cylinders 44 pass through the first fixing plate 43 and are fixedly connected to the back of the second turntable 41, the second motor 49 is fixed on the frame 1, and the drive end of the second motor 49 is fixedly connected to the first fixing plate 43.
[0035] When the second turntable assembly 4 winds up the hose, each of the two first turntable assemblies 2 winds up half of the hose, with the middle of the hose passing through the second turntable assembly 4. The third cylinder 45 moves one second clamping rod 42, and the fourth cylinder 46 moves another second clamping rod 42. The two second clamping rods 42 move closer together, clamping the middle of the hose, while the first clamping rod 22 releases the hose. Then, driven by the second motor 49, the second turntable assembly 4 rotates clockwise, winding the hose from the two first turntable assemblies 2 onto itself until the hose is completely wound onto the second clamping rod 42, completing the winding process. Next, the two fifth cylinders 44 extend, pushing the second turntable 41 forward. The forward-moving second turntable 41 pushes the wound hose from the second clamping rod 42 onto the frame 1, where firefighters retrieve it, completing the cleaning and winding of the hose.
[0036] Furthermore, it also includes a gun head component 5, which includes a second fixing plate 51, a fifth fixing bracket 52, a gun head 53, a pipe 55, a U-shaped bracket 54, and an adjusting component. The second fixing plate 51 is fixed to the frame 1, the fifth fixing bracket 52 is fixed to the second fixing plate 51, the U-shaped bracket 54 is rotatably connected to the top of the fifth fixing bracket 52, the gun head 53 is rotatably connected to the U-shaped bracket 54, the adjusting component is disposed on the fifth fixing bracket 52, and the adjusting component is connected to the gun head 53 to drive the gun head 53 to adjust the angular direction, and the pipe 55 passes through the second fixing plate 51, the fifth fixing bracket 52, and the U-shaped bracket 54 and is connected to the gun head 53.
[0037] During firefighting, the hose is connected to pipe 55, and the water transported by the hose is then delivered to the nozzle 53 through pipe 55. The nozzle is then sprayed onto the fire source to extinguish the fire. With the adjustment mechanism, the U-shaped frame 54 rotates on the fifth fixed frame 52 to adjust the horizontal direction of the nozzle 53, and the nozzle 53 rotates on the U-shaped frame 54 to adjust the elevation angle. These adjustments allow the nozzle 53 to be aimed precisely at the fire source for accurate firefighting.
[0038] Furthermore, the adjusting components include a third motor 71, a fourth motor 72, a first worm 73, a second worm 76, a first worm gear 75, a second worm gear 74, a first bevel gear 70, a second bevel gear 79, a rotating shaft 56, an adjusting rod 77, and an adjusting sleeve 78. The third motor 71 and the fourth motor 72 are both fixed to the second fixed plate 51. The power output end of the third motor 71 is connected to the first worm 73 via a coupling, and the power output end of the fourth motor 72 is connected to the second worm 76 via a coupling. The gun head 53 is fixed to the rotating shaft 56, and the rotating shaft 56 is rotatably connected to the U-shaped frame 54. The first bevel gear 70 is sleeved on the rotating shaft 56, and the second bevel gear 79... Wheel 79 is rotatably connected to the inner bottom wall of U-shaped frame 54 via first rolling bearing 81. First bevel gear 70 meshes with second bevel gear 79. One end of adjusting rod 77 is rotatably connected to second fixed plate 51. The other end of adjusting rod 77 passes through fifth fixed frame 52 and U-shaped frame 54 and is fixedly connected to second bevel gear 79. First worm gear 75 is sleeved on adjusting rod 77. First worm 73 meshes with first worm gear 75. Adjusting sleeve 78 is sleeved on adjusting rod 77. Top of adjusting sleeve 78 passes through fifth fixed frame 52 and is fixedly connected to bottom of U-shaped frame 54. Second worm gear 74 is sleeved on adjusting sleeve 78. Second worm 76 meshes with second worm gear 74.
[0039] The adjusting mechanism controls the rotation of the third motor 71 and the fourth motor 72 to adjust the horizontal and vertical directions of the gun head 53. The third motor 71 drives the first worm gear 73 to rotate, which in turn drives the first worm wheel 75 to rotate. The rotating first worm wheel 75 drives the adjusting rod 77 to rotate, which in turn drives the second bevel gear 79 to rotate. The second bevel gear 79, through meshing, drives the first bevel gear 70 to rotate, which in turn drives the first bevel gear 70 to rotate, thereby adjusting the vertical angle of the gun head 53. The fourth motor 72 drives the second worm gear 76 to rotate, which in turn drives the second worm wheel 74 to rotate. The rotating second worm wheel 74, through the adjusting sleeve 78, drives the U-shaped bracket 54 to rotate, thereby achieving horizontal adjustment of the gun head 53.
[0040] Furthermore, the gun head component 5 also includes a camera 58 and a mounting base 57. The rotating shaft 56 passes through the side of the U-shaped frame 54 and is fixedly connected to the mounting base 57. The camera 58 is fixed on the mounting base 57. The movement of the camera 58 is synchronized with the gun head 53, enabling the gun head 53 to aim at the center of the fire source observed by the camera 58 and spray water to extinguish the fire.
[0041] Furthermore, wheels 11 are rotatably connected to the side of the frame 1.
[0042] Furthermore, it also includes a power component 6, which comprises a fifth motor 61, a synchronous belt 64, a first synchronous pulley 63, a second synchronous pulley 66, a bearing housing 65, and a drive shaft 67. The fifth motor 61 is fixed to the frame 1 via a bracket 62. The first synchronous pulley 63 is fixed to the power output end of the fifth motor 61. The bearing housing 65 is fixed to the bottom of the frame 1. The drive shaft 67 is rotatably connected to the bearing housing 65. One end of the drive shaft 67 is fixedly connected to one of the wheels 11 via a flange coupling 68. The second synchronous pulley 66 is fixed to the drive shaft 67. The synchronous belt 64 is sleeved over the first synchronous pulley 63 and the second synchronous pulley 66. When the equipment moves, the fifth motor 61 drives the first synchronous pulley 63 to rotate. The rotating first synchronous pulley 63 drives the second synchronous pulley 66 to rotate via the synchronous belt 64, which in turn drives the wheel 11 to rotate via the drive shaft 67, thus realizing the overall movement of the equipment.
[0043] Furthermore, a sponge sleeve is fitted over the first clamping rod 22. The sponge sleeve allows for a more thorough cleaning as the water hose slides across, resulting in a better cleaning effect.
[0044] Furthermore, the U-shaped frame 54 and the fifth fixed frame 52 are connected by a second rolling bearing 82.
[0045] Furthermore, a shaft retaining ring 69 is fitted onto the other end of the drive shaft 67.
[0046] Other techniques in this embodiment are based on existing technologies.
