Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, and in particular to a multi-mode fire extinguishing operation equipment. Background Technology

[0002] In the field of firefighting operations, efficient and flexible firefighting equipment is key to improving firefighting efficiency and reducing loss of life and property. However, current firefighting equipment on the market still has many limitations in practical applications and cannot meet the needs of complex and ever-changing firefighting scenarios. On the one hand, the water flow angle adjustment of traditional fire hoses mostly relies on adjusting the overall posture of the hose body, which is cumbersome to operate and has low adjustment accuracy. Especially when dealing with fire points in special locations such as high-rise buildings and confined spaces, it is difficult to accurately aim at the fire source, which can easily lead to blind spots in firefighting and reduce the timeliness of firefighting.

[0003] On the other hand, existing firefighting equipment has significant shortcomings in water flow mode switching. Most equipment can only achieve a single direct stream of water or a fixed-range atomized spray. Switching between the two modes often requires replacing the nozzle or the entire gun head, which is cumbersome and time-consuming, and cannot quickly adapt to changes in fire intensity. In addition, some equipment with atomization capabilities has a fixed water mist range, which cannot be flexibly adjusted according to the fire situation on site. This results in either low firefighting efficiency due to insufficient coverage or water waste due to excessively dispersed water mist. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-mode fire extinguishing equipment, which aims to improve the problems of existing technologies that cannot be flexibly adjusted according to the fire situation on site, or that the fire extinguishing efficiency is low due to the small coverage area, or that water resources are wasted due to the excessive dispersion of water mist.

A guide ring is fixedly connected to the inner wall of the rotating ring, and the outer wall of the guide ring is in close contact with the inner wall of the nozzle. The inner wall of the guide ring has a spiral pattern, and one end of an L-shaped rod is slidably connected to the inside of the spiral pattern. The other end of the L-shaped rod is fixedly connected to a limit block, which is slidably connected to a frame assembly located at one end of the inner wall of the nozzle. A rotating shaft is installed on the top of the frame assembly, and a guide plate is fixedly connected to one side of the outer wall of the rotating shaft. One side of the outer wall of the guide plate is fixedly connected to the frame assembly by a tension spring.

[0014] As a further description of the above technical solution:

[0015] The atomizing assembly includes a switching ring rotatably connected to one side of the outer wall of the nozzle, with its inner wall extending into the nozzle. One end of a fixing post is installed on one side of the outer wall of the nozzle, and the other end of the fixing post is rotatably connected to a rotating plate. A slot is formed on one side of the outer wall of the rotating plate. A guide rod is fixedly connected to one side of the inner wall of the switching ring, with one end of the guide rod extending into the slot. A microporous atomizing plate is fixedly connected to the other side of the outer wall of the rotating plate, and multiple microporous atomizing plates form a microporous atomizing plate.

[0016] As a further description of the above technical solution:

[0017] A connecting shaft is fixedly connected to one side of the outer wall of the guide plate. The connecting shaft is installed on one side of the outer wall of the guide plate. An extension plate is fixedly connected to one side of the outer wall of the connecting shaft. The extension plate is connected to one side of the outer wall of the guide plate by a spring.

[0018] As a further description of the above technical solution:

Different fire situations can be dealt with without changing equipment, significantly improving fire extinguishing efficiency. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1-4 One embodiment of this utility model is a multi-mode fire extinguishing equipment, comprising:

[0035] Gun body 1, as one of the basic components of the overall structure, is used to assemble and support various processing mechanisms and their conveying pipes 2. The two ends of the conveying pipes 2 are connected to the rear end of the gun body 1 and the water source, respectively.

[0036] A lever-type control valve 3 is located in the middle of the gun body 1 and is used to control the water flow of the gun body 1.

[0037] The nozzle 4 is located inside the gun body 1, through which water flows;

[0038] Nozzle 5, which is located at the front end of gun body 1, is used to spray water to impact the ignition point.

[0039] The pitch adjustment component 6 is located inside the nozzle 5 and is used to adjust the angle of the water jet.

[0040] The atomizing component 7, located inside the nozzle 5, is used to refine the water flow.

[0041] The pitch adjustment assembly 6 includes a rotating ring 601, which is rotatably connected to the middle of the outer wall of the gun body 1. Its inner wall extends into the gun body 1. A guide ring 602 is fixedly connected to the inner wall of the rotating ring 601. The outer wall of the guide ring 602 is in close contact with the inner wall of the nozzle 4. The inner wall of the guide ring 602 is provided with a spiral pattern 603. One end of an L-shaped rod 604 is slidably connected inside the spiral pattern 603. The other end of the L-shaped rod 604 is fixedly connected to a limiting block 605. The limiting block 605 is slidably connected inside a frame assembly 606 located at one end of the inner wall of the nozzle 4. A rotating shaft 607 is installed on the top of the frame assembly 606. A guide plate 608 is fixedly connected to one side of the outer wall of the rotating shaft 607. One side of the outer wall of the guide plate 608 is fixedly connected to the frame assembly 606 by a tension spring 609.

[0042] The L-shaped rod 604 extends into one end of the spiral pattern 603 and is rotatably connected to a roller 613.

[0043] The cross-section of the rotating ring 601 is H-shaped, and the cross-section of the limiting block 605 group is L-shaped.

[0044] Specifically, when it is necessary to adjust the pitch angle of the water jet, the operator rotates the rotating ring 601 on the outer wall of the gun body 1. The rotating ring 601 drives the guide ring 602 inside it to rotate synchronously. Since the roller 613 at one end of the L-shaped rod 604 is slidably connected in the spiral pattern 603 on the inner wall of the guide ring 602, the rotational motion of the guide ring 602 is converted into the linear motion of the L-shaped rod 604 along the axis of the nozzle 4 through the spiral pattern 603. The L-shaped rod 604 pushes or pulls the limiting block 605 at its other end to slide within the frame assembly 606. The linear motion of the limit block 605 causes the entire frame assembly 606 and the rotating shaft 607 mounted on it to move, thereby forcing the guide plate 608, which is fixed to the rotating shaft 607, to deflect around the rotating shaft 607. The guide plate 608 is the last guiding mechanism through which the water flows, and the change in its angle directly determines the pitch angle when the water flows out of the nozzle 5. The function of the tension spring 609 is to provide damping and maintain the stability of the guide plate 608 during the adjustment process, preventing it from generating unexpected vibrations or displacements under the impact of high-pressure water flow. Through this mechanical linkage, stepless and linear control from external rotation operation to internal water flow angle adjustment is achieved.

[0045] The atomizing assembly 7 includes a switching ring 701, which is rotatably connected to one side of the outer wall of the nozzle 5. Its inner wall extends into the interior of the nozzle 5. One end of a fixing post 702 is installed on one side of the outer wall of the nozzle 4. The other end of the fixing post 702 is rotatably connected to a rotating plate 703. A slot 704 is opened on one side of the outer wall of the rotating plate 703. A guide rod 705 is fixedly connected to one side of the inner wall of the switching ring 701. One end of the guide rod 705 extends into the slot 704. A microporous atomizing plate 706 is fixedly connected to the other side of the outer wall of the rotating plate 703. Multiple microporous atomizing plates 706 form a microporous atomizing plate 707.

[0046] Specifically, when atomized water flow is required, the operator rotates the switching ring 701 on the outer wall of nozzle 5. The switching ring 701 drives the guide rod 705 fixed on its inner wall to make a circular motion. Since the end of the guide rod 705 extends into the slot 704 on the rotating plate 703, its circular motion is constrained by the contour of the slot 704 and is converted into a driving force on the rotating plate 703. This driving force drives the rotating plate 703 to rotate around its connection point with the fixed column 702. Multiple rotating plates 703 rotate synchronously, driving the microporous atomizing plate 706 fixed on it to flip from the side wall position of the nozzle 5 to the center of the water flow channel. When the high-pressure water flow passes through, it is cut and impacted by the microporous atomizing plate 707 and passes through the micron-level pores on its surface, thus being fully broken and refined to form a water mist with a large coverage area. When switching back to the DC mode, the switching ring 701 is rotated in the opposite direction, and the guide rod 705 drives the rotating plate 703 to reverse, causing the microporous atomizing plate 707 to flip and exit the main water flow channel, and the water flow can be ejected in the form of a concentrated water column without obstruction.

[0047] A connecting shaft 610 is fixedly connected to one side of the outer wall of the guide plate 608. The connecting shaft 610 is installed on one side of the outer wall of the guide plate 608. An extension plate 611 is fixedly connected to one side of the outer wall of the connecting shaft 610. The extension plate 611 is connected to one side of the outer wall of the guide plate 608 by a spring 612.

[0048] The microporous atomizing plate 706 is fixedly connected to the corresponding rotating plate 703 at an angle, and the cross section of the microporous atomizing plate 707 is a transverse V-shape.

[0049] Specifically, it is worth mentioning that in this embodiment, the guide plate 608 can change its tilt angle as the L-shaped rod 604 moves linearly, thereby changing the direction of water flow on one side. While the tilt angle of the guide plate 608 changes, the extension plate 611, under the action of the spring 612, always remains in close contact with the outer wall of the microporous atomizing plate 707 in atomization mode. At this time, a large amount of water flow only passes through the surface of the extension plate 611. With the extension plate 611 blocking part of the through holes on the surface of the microporous atomizing plate 707, the range of water mist sprayed can be adjusted. The range of water mist can be flexibly adjusted according to the situation of fire extinguishing, thereby improving the fire extinguishing efficiency.

[0050] Working principle: First, the water source is connected to the rear end of the gun body 1 through the delivery pipe 2. The operator can control the water flow through the lever control valve 3 located in the middle of the gun body 1. The water flows through the nozzle 4 inside the gun body 1 to the nozzle 5 at the front end. When it is necessary to adjust the water jet pitch angle, the rotating ring 601 on the outer wall of the gun body 1 is rotated. The rotating ring 601 drives the guide ring 602 fixed on the inner wall to rotate synchronously. Since one end of the L-shaped rod 604 extends into the spiral pattern 603 and is connected to the roller 613, the roller 613... Sliding within the spiral pattern 603 on the inner wall of the guide ring 602 causes the L-shaped rod 604 to move linearly along the axis of the nozzle 4, thereby pushing or pulling the L-shaped cross-section limiting block 605 fixed at the other end to slide within the frame assembly 606. The limiting block 605 causes the frame assembly 606 and the top rotating shaft 607 to shift, forcing the guide plate 608 fixed to the rotating shaft 607 to deflect around the rotating shaft 607. The tension spring 609 provides damping and keeps the guide plate 608 stable. At the same time, the guide plate 608 is connected to the connecting shaft 61. The fixed extension plate 611, under the action of spring 612, always adheres to the relevant components, thereby changing the pitch angle of the water jet nozzle 5. When it is necessary to switch the water flow mode, the switching ring 701 on the outer wall of the nozzle 5 is rotated. The switching ring 701 drives the guide rod 705 on the inner wall to make a circular motion. The end of the guide rod 705 moves in the slot 704 of the rotating plate 703, driving the rotating plate 703 to rotate around the connection point with the fixed column 702, so that the micropores fixed on the rotating plate 703 and set at an angle are atomized. The plate 706 flips to the center of the water flow channel or retracts. When flipped to the center, the high-pressure water flow is refined into water mist through the micron-level pores of the microporous atomizing plate 707 and sprayed out. When retracted, it forms a concentrated water column. The extension plate 611 can block part of the through holes of the microporous atomizing plate 707 in atomization mode to achieve water mist range adjustment. Finally, through the synergistic effect of various components, the water flow is delivered, the flow rate is controlled, the pitch angle is adjusted, and the switching between DC and atomization modes is achieved to meet the needs of different fire extinguishing scenarios.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
