Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting and fire extinguishing, in particular to a fire fighting device capable of accurately extinguishing fire. Background Art

[0002] Fire-fighting equipment is equipment and systems used to prevent, control and extinguish fires. Common fire-fighting equipment includes fire alarm systems, automatic sprinkler systems, fire extinguishers, smoke sensors, emergency evacuation signs, etc.

[0003] For example, a Chinese utility model patent (CN 215505287 U) discloses an angle adjustment device for a large-scale water sprinkler head for firefighting and rescue with precise fire extinguishing, which records: "The annular block is driven to rotate by the first teeth and the second teeth, and then the overall angle deflection is achieved through the chassis, so that the large-scale water sprinkler can extinguish fires at different angles, which is convenient for staff to operate." It also records: "At present, staff usually use large-scale water sprinklers when extinguishing fires at the fire scene. However, the angle adjustment structure of general large-scale water sprinklers is relatively simple, which makes the large-scale water sprinklers less effective when adjusting the angle, and cannot meet the needs of staff to extinguish fires at different angles, thereby causing inconvenience to the staff's operation." Technical problems.

[0004] In summary, it can be seen that the prior art utilizes the overall angle deflection in the horizontal plane to extinguish fires at different angles. However, this method has the following technical problems: for water gun fire extinguishing, the water gun should be aimed at the root of the fire source for rapid fire extinguishing. Merely rotating the entirety in the horizontal plane makes it impossible to aim the water gun head at the root of the fire source according to actual conditions, which results in the low practicality of the device. For this reason, the present application proposes a fire-fighting device that can accurately extinguish fires, and provides a new technical solution to solve the technical problems mentioned in the above patents.

Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As in the background art, when extinguishing a fire with a water gun, the water gun should be aimed at the root of the fire source to quickly extinguish the fire. Simply rotating the entire gun in a horizontal plane cannot allow the water gun head to be aimed at the root of the fire source according to actual conditions, which results in low practicability of the device.

[0029] In order to solve this technical problem, the utility model provides a fire-fighting device that can accurately extinguish fires, which is a fire-fighting device used to accurately and quickly extinguish fires at the root of fire sources.

[0030] Specifically, please refer to Figure 1-Figure 2 , fire-fighting devices that can accurately extinguish fires specifically include:

[0031] The device comprises a base 1, a universal brake wheel 2 is fixedly connected to the bottom of the base 1, a push rod 3 is fixedly connected to the top of the base 1, an adjustment mechanism 4 is arranged on the top of the base 1, a stabilizing mechanism 5 is arranged inside the adjustment mechanism 4, a water pump 6 is installed on the top of the adjustment mechanism 4, a water inlet pipe 7 is fixedly connected to the water suction end of the water pump 6, a water outlet pipe 8 is fixedly connected to the water outlet end of the water pump 6, and a fixed housing 10 is fixedly connected to the end of the water outlet pipe 8 away from the water pump 6;

[0032] The adjustment mechanism 4 includes a fixed housing 10 fixedly connected to the top of the device base 1 , a servo motor 11 is fixedly connected to the interior of the fixed housing 10 , and a connecting shaft 12 is fixedly connected to the output end of the servo motor 11 .

[0033] The fire-fighting device that can accurately extinguish fires provided by the utility model starts the servo motor 11 according to the location of the fire source, drives the connecting shaft 12 to rotate, and then rotates to a suitable angle through the glass window 16 with the calibration line 15 as an aid and the scale on the scale 14 as a standard, so that the position of the water gun head 9 is directly opposite to the fire position, and then the sliding block 21 is driven to slide inside the limiting track 19 through the lifting and lowering of the hydraulic rod 20, so that the rotating frame 18 and the receiving plate 17 rotate relative to each other, and then drives the water gun head 9 to change the angle in the vertical plane, and adjusts the water gun head 9 to aim at the root of the fire source, so as to achieve accurate and rapid fire extinguishing, avoid the fire from spreading and the objects around the fire source from being damaged by water, make the device closer to actual use, and the device has higher practicality.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1:

[0036] Please refer to Figure 1-Figure 3 , a fire-fighting device capable of accurately extinguishing fire, comprising:

[0037] The outside of the connecting shaft 12 is fixedly connected with a disk 13 , and the inside of the disk 13 is fixedly connected with a scale 14 . The scale 14 can reflect the rotation angle, thereby accurately extinguishing the fire source. The disk 13 is rotatably connected to the inside of the fixed shell 10 .

[0038] A calibration line 15 is fixedly connected to the interior of the fixed shell 10, and a glass window 16 is fixedly connected to the interior of the fixed shell 10. The operator can see the scale on the scale 14 opposite to the calibration line 15 through the glass window 16, which is convenient for the operator to observe and adjust. The end of the connecting shaft 12 away from the servo motor 11 is fixedly connected to a receiving plate 17, and the receiving plate 17 is rotatably connected to the interior of the fixed shell 10.

[0039] The top of the receiving plate 17 is rotatably connected to a rotating frame 18, the bottom of the rotating frame 18 is fixedly connected to a limiting track 19, and the top of the receiving plate 17 is fixedly connected to a hydraulic rod 20. The lifting and lowering of the hydraulic rod 20 drives the angle of the rotating frame 18 to change, so that the water gun head 9 can be further aimed at the root of the fire source, thereby achieving accurate and rapid fire extinguishing. The end of the hydraulic rod 20 away from the receiving plate 17 is rotatably connected to a sliding block 21, and the sliding block 21 is slidably connected to the inside of the limiting track 19.

[0040] Through the above structural design, after determining the direction of the fire source, start the servo motor 11 to drive the connecting shaft 12 to rotate, and then use the calibration line 15 as an aid through the glass window 16, and the scale on the scale 14 as a standard, and rotate to a suitable angle. The connecting shaft 12 drives the receiving plate 17 to rotate to a suitable angle, so that the position of the water gun head 9 is aligned with the fire position, and the hydraulic rod 20 is controlled to rise and fall, so that the angle between the hydraulic rod 20 and changes accordingly. At the same time, the sliding block 21 slides inside the limiting track 19, so that the rotating frame 18 and the receiving plate 17 rotate relative to each other, thereby driving the angle of the water gun head 9 to change in the vertical plane, and adjusting the water gun head 9 to align with the root of the fire source.

[0041] Embodiment 2:

[0042] The fire-fighting device capable of accurately extinguishing fire provided in Example 1 is further optimized. Specifically, Figure 1-Figure 5 As shown,

[0043] The stabilizing mechanism 5 includes a threaded rod 22 threadedly connected to the inside of the rotating frame 18, and the end of the threaded rod 22 away from the water gun head 9 is fixedly connected to a rotating disk 23, and the outside of the rotating disk 23 is fixedly connected to a grip rod 24. The grip rod 24 makes it convenient for the staff to clamp the water gun head 9 without using tools, thereby preventing the water gun head 9 from detaching under the reaction force of the water flow, thereby improving the stability of the device.

[0044] One end of the threaded rod 22 away from the rotating disk 23 is fixedly connected to a fixed block 25, and a ball 26 is movably connected inside the fixed block 25. The ball 26 can drive a clamping plate 27 to fit closely to water gun heads 9 of different models, thereby improving the practicality of the device. The outside of the ball 26 is fixedly connected to a clamping plate 27.

[0045] Through the above-mentioned structural design, holding the handle 24 drives the rotating disk 23 to rotate, and then drives the threaded rod 22 to rotate, and then drives the splint 27 to move closer to or away from the water gun head 9. The water gun head 9 can be quickly fixed and removed without the aid of tools, thereby improving the efficiency of fire extinguishing and subsequent maintenance. Since different water gun heads 9 have different external curvatures, when the splint 27 gradually fits tightly against the water gun head 9, the rolling ball 26 will move accordingly in the ball cavity in the fixed block 25, so that the splint 27 can adapt to different water gun heads 9.
