Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, specifically to a sliding wire fire extinguishing device. Background Art

[0002] Most of the electrolysis workshop is a closed space, which is prone to fire under high temperature and poor ventilation. The excessive number of partitions and columns in the workshop seriously hinders the efficiency of ground fire extinguishing. In addition, the sliding contact line of the electrolysis workshop's sliding contact line power supply system may cause fires due to poor contact or large starting current during operation. Considering the risks of personnel falling from height and other secondary safety hazards when extinguishing fires on the track, a high-altitude sliding contact line fire extinguishing device is needed.

[0003] Chinese patent document CN110227225A discloses an intelligent track fire extinguisher. It features a drive shaft on a trolley with rollers fixed to its outer end. The rollers are placed within a track. The trolley also houses a drive motor and a housing disassembly / removal motor. A steering shell is rotatably mounted in the lower center of the housing, with a gear ring on its upper edge. A gear at the output of a small motor meshes with the gear ring. An angle adjustment tube is rotatably connected inside the steering shell, and a rack is connected to the angle adjustment tube. The output of the angle adjustment motor, through gear meshing with the rack, pulls the angle adjustment tube to adjust the pitch. This design can respond to fires in real time, quickly pinpointing the location of the fire, then driving the device along the track to the nearest point of the fire, automatically adjusting the direction of the spray nozzles to extinguish the fire.

[0004] The above solution still has several areas for improvement: it lacks the ability to adjust the nozzle angle, making it impossible to accurately aim at the fire point and easily wasting fire-fighting materials; the nozzle lacks auxiliary fixing components, and the impact force of the liquid will cause the direction to deviate when spraying fire-fighting liquid.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1 to 7 As shown, a sliding fire extinguishing device includes a steering wheel 1, a fire extinguishing tank 6, a nozzle 7, a crane 8, and a sliding rail 9. The steering wheel 1 includes a driving wheel 2, a driven wheel 3, a boss 4, and a first rotating shaft 5. The steering wheel 1 is fixedly installed at the bottom of the fire extinguishing tank 6. The nozzle 7 is installed on the steering wheel 1 and connected to the fire extinguishing tank 6. The crane 8 passes through the sliding rail 9 and is installed above the fire extinguishing tank 6. At the same time, the bottom of the crane 8 is connected to the top of the fire extinguishing tank 6. The driving wheel 2 is installed on the steering wheel 1 and connected to the bottom of the fire extinguishing tank 6. The driven wheel 3 is installed on the steering wheel 1 and is located at the bottom center of the fire extinguishing tank 6. The boss 4 is installed on the driven wheel 3. The first rotating shaft 5 is rotatably connected to the boss 4 and fixed to the tail of the nozzle 7.

[0027] The device's crane 8 moves along the slide rail 9, carrying the fire extinguishing tank 6 to the fire location. The fire extinguishing tank 6 stores fire-fighting liquid. The direction and angle of the nozzles 7 are controlled by the steering wheel 1, and finally, the nozzles 7 are aimed at the fire to extinguish it. The drive wheel 2 is controlled by a motor installed at the bottom of the fire extinguishing tank 6, which is controlled by a remote control device on the ground. The drive wheel 2 drives the driven wheel 3, which meshes with it, to rotate, thereby changing the direction of the nozzles 7 on the driven wheel 3. The boss 4 is used to install the first rotating shaft 5. The rotation of the first rotating shaft 5 is controlled by the remote control device to control the angle of the nozzles 7, so that the fire extinguishing device can cover the fire at any location.

[0028] See Figures 1 to 3 As shown, the driven wheel 3 includes a receiver 31, a first gear 32, and a stopper 33. The receiver 31 is mounted on the driven wheel 3 and is located on one side of the boss 4. The stopper 33 is mounted on the other side of the boss 4 on the driven wheel 3. The first gear 32 is rotatably mounted on the receiver 31 and contacts the first rotating shaft 5.

[0029] The receiver 31 is controlled by the ground remote control equipment to drive the first gear 32 to rotate, and the first gear 32 drives the first rotating shaft 5 to rotate. The stop device 33 is also controlled by the ground remote control equipment to fix the angle of the sprinkler head 7 after adjustment, so as to prevent the sprinkler head 7 from deviating due to the reaction force of the sprayed fire-fighting liquid.

[0030] See Figures 1-4 As shown, the stop device 33 includes a stop plate 331, a telescopic rod 332 and a spring 333. One end of the telescopic rod 332 is installed on the side of the stop device 33, and the other end is connected to the bottom of the stop plate 331. The spring 333 surrounds the outside of the telescopic rod 332.

[0031] The clamping plate 331 is used to fix the rotation of the first rotating shaft 5. When the stopper 33 is not under force, the spring 333 is in a relaxed state, and the telescopic rod 332 pushes the clamping plate 331 against the first rotating shaft 5 to prevent it from rotating. When it is necessary to adjust the angle of the nozzle 7, the telescopic rod 332 retracts and the spring 333 is compressed, and the clamping plate 331 leaves the first rotating shaft 5. At this time, the first rotating shaft 5 can rotate. After the angle is adjusted, the spring 333 resets and the clamping plate 331 fixes the first rotating shaft 5 again.

[0032] See Figures 2-4 As shown, the first rotating shaft 5 includes a second gear 51 and a fixed platform 52. The second gear 51 is installed on both sides of the first rotating shaft 5, and the fixed platform 52 is fixedly connected to the first rotating shaft 5 and fixedly connected to the tail of the nozzle 7.

[0033] The second gear 51 has two parts. One is driven to rotate by the first gear 32 on the driven wheel 3, and the other contacts the locking plate 331 on the stopper 33 to stop the rotation of the first rotating shaft 5. The fixed platform 52 is used to install the nozzle 7 and prevent the nozzle 7 from falling off the steering wheel 1.

[0034] See also Figures 1-5 As shown, the fire extinguishing tank 6 includes an inlet 61, an outlet 62, and a wiring 63. The inlet 61 is located at the top of the fire extinguishing tank 6, the outlet 62 is located at the bottom of the fire extinguishing tank 6, and one end of the wiring 63 is connected to the outlet 62, while the other end is connected to the nozzle 7.

[0035] The inlet 61 allows for the addition and replenishment of fire-fighting liquid, ensuring the device can be used for a long time. The outlet 62 is located at the bottom of the fire extinguishing tank 6. Under the action of gravity, the fire-fighting liquid can spontaneously enter the nozzle 7 through the wiring 63 for fire extinguishing.

[0036] See also Figures 1-6 As shown, the nozzle 7 includes an inner rotating head 71, an outer rotating head 72, a through hole 73, and a main hole 74. The inner rotating head 71 is disposed in the cavity of the nozzle 7, the outer rotating head 72 is rotatably mounted on the top of the inner rotating head 71, the through holes 73 are arrayed on the surfaces of the inner rotating head 71 and the outer rotating head 72, and the main hole 74 is disposed at the center of the inner rotating head 71 and the outer rotating head 72.

[0037] The rotation and engagement of the inner rotating head 71 and the outer rotating head 72 determine whether the through hole 73 is open, while the main hole 74 remains open. When the through hole 73 is open, the spraying area of ​​the nozzle 7 increases, making it suitable for large-area fire extinguishing. When the through hole 73 is closed, the main hole 74 of the nozzle 7 performs single-point, high-pressure fire extinguishing, suitable for extinguishing a single fire.

[0038] See also Figures 1 to 7 As shown, the crane 8 includes a slot 81, rollers 82 and a lift 83. The slot 81 is located in the middle of the crane 8, the rollers 82 are installed on the top of the crane 8 and contact the slide rail 9, and the lift 83 is installed at the bottom of the crane 8.

[0039] The slide rail 9 passes through the slot 81, allowing the crane 8 to move stably on the slide rail 9. The roller 82 changes the friction between the crane 8 and the slide rail 9 from sliding friction to rolling friction, reducing the moving resistance and improving the service life of both. The elevator 83 is used to control the raising and lowering of the fire extinguishing tank 6 so as to replenish the fire extinguishing liquid and maintain the parts of the fire extinguishing tank 6 in a timely manner.

[0040] See also Figure 7As shown, the elevator 83 includes a second rotating shaft 831, a hoisting rope 832, and a controller 833. The controller 833 is installed at both ends of the crane 8. The second rotating shaft 831 passes through the elevator 83 and is connected to the controller 833. The hoisting rope 832 is wound around the second rotating shaft 831 and connected to the top of the fire extinguishing tank 6.

[0041] The second rotating shaft 831 controls the raising and lowering of the hoisting rope 832, thereby controlling the lifting and lowering of the fire extinguishing tank 6. The controller 833 is controlled by the ground remote control equipment, which drives the second rotating shaft 831 to rotate while controlling the rotation of the roller 82, thereby moving the crane 8.

[0042] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
