Description

Technical Field

[0001] The invention relates to the technical field of fire monitors, in particular to a column-mist switching fire monitor. Background Art

[0002] Fire water cannon is a fire-fighting equipment that uses water as a medium to extinguish fires at a long distance. It can be divided into automatic sweeping high-altitude water cannon, solid manual fire water cannon, automatic homing fire water cannon, electronically controlled fire water cannon, etc. Its working principle usually involves infrared and ultraviolet light sensing technology. Through the embedded CPU and optimization algorithm, it can quickly and accurately detect the early stage of a fire and respond, automatically start the fire extinguishing system, and automatically stop spraying after the fire is under control, and supports repeated start and stop.

[0003] The Chinese invention patent document with publication number CN113582484A discloses a fire-fighting water monitor, comprising a base, a barrel mounted on the base, and a gun head mounted on the barrel, wherein the gun head comprises two or more gun head modules with different minimum flow cross-sectional areas, and the jet flow rate of the fire-fighting water monitor is changed by selecting one or more of the gun head modules on the barrel. By changing the number and / or specifications of the gun head modules of the fire-fighting water monitor, the water outlet area of ​​the fire-fighting water monitor is changed, and then the jet flow rate is changed to achieve the purpose of adjusting the range. At the fire scene, firefighters can combine and install different gun head modules according to the distance from the fire point to quickly adjust the range of the fire-fighting water monitor.

[0004] The above-mentioned fire water cannon has certain shortcomings when being used and operated. The above-mentioned fire water cannon does not have a water state switching structure, so that the above-mentioned fire water cannon can only perform columnar water spraying operations when in use. When the user is close to the fire source, the above-mentioned fire water cannon cannot switch to mist spraying for close-range and large-scale fire extinguishing, and the functionality is single; secondly, the traditional fire water cannon can only perform columnar or mist spraying operations when in use. The mist spraying can be used for cooling and protecting firefighters, while the columnar spraying can directly hit the fire source and play a major fire extinguishing role. The traditional fire water cannon cannot flexibly open the two states, and the fire extinguishing effect is not ideal. Summary of the invention

[0005] The technical problem to be solved by the present invention is how to open both columnar and mist states at the same time.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A column mist switching fire monitor comprises a monitor head, a first tube body and a second tube body, wherein two ends of the second tube body are respectively connected to the monitor head and the first tube body;

[0008] The gun head includes a main nozzle, a telescopic sleeve, an auxiliary nozzle, and a fixed nozzle. One end of the main nozzle is connected to the second tube body, and the outer wall of the other end is movably connected to the telescopic sleeve. The auxiliary nozzle is fixed inside the main nozzle, and the output end of the auxiliary nozzle extends outward from the telescopic sleeve and is connected to the fixed nozzle. The outer side of the fixed nozzle and the inner side of the output end of the telescopic sleeve are both inclined structures, so that a spray groove is formed between the fixed nozzle and the telescopic sleeve.

[0009] The main nozzle is used to form a mist water shield protection structure towards the spray slot, which protects the user who controls the fire water monitor head, and the auxiliary nozzle is used to inject water into the fixed nozzle. The columnar water sprayed from the fixed nozzle can effectively control the fire and play a major role in extinguishing the fire. At the same time, because the auxiliary nozzle and the main nozzle are independently supplied with water, the fixed nozzle will not reduce the water pressure in the main nozzle when used synchronously, so that the mist and columnar water flow are sprayed out in a high-pressure state, allowing the user to continuously perform fire extinguishing operations while approaching the fire source, thereby improving the fire extinguishing effect.

[0010] Preferably, the main nozzle is connected to the second pipe body through a branch sleeve.

[0011] Preferably, a water inlet joint is fixedly installed at the water inlet end of the auxiliary nozzle, a docking socket is fixedly installed on the inner side of the branch sleeve, and the water inlet joint is connected to the docking socket.

[0012] Preferably, it also includes a direct current tube, which passes through the branch sleeve and is connected to the docking socket. The docking socket and the branch sleeve are fixed by two groups of fixed chucks, and a plurality of through holes are provided on the fixed chucks.

[0013] Preferably, a sloped nozzle is provided inside the fixed nozzle, and the output port diameter of the sloped nozzle is smaller than the input port diameter.

[0014] Preferably, a valve is provided on the auxiliary nozzle.

[0015] Preferably, the main nozzle is connected to the telescopic sleeve through a driving assembly, and the driving assembly includes a driving motor, a screw and a fixing nut. The driving motor is fixed to the outer wall of the main nozzle, and the fixing nut is fixed to the outer wall of the telescopic sleeve. One end of the screw is connected to the driving motor, and the other end is threadedly connected to the fixing nut.

[0016] Preferably, a connecting seat is fixed to the outer wall of the main nozzle, a limiting seat is arranged on the telescopic sleeve, a guide rod is fixed on the connecting seat, and one end of the guide rod away from the connecting seat passes through the limiting seat and is slidably connected to the limiting seat.

[0017] Preferably, a movable base is installed at the water inlet end of the first tube body, and a lifting frame and two sets of guide plates are movably installed at the bottom of the movable base. The two sets of guide plates are located on one side of the lifting frame and are symmetrically arranged in an inclined shape.

[0018] Preferably, both ends of the lifting frame are connected to the bottom of the mobile base through a lifting rod, and a telescopic tube is connected to the lifting frame. One end of the telescopic tube passes through the mobile base and is connected to the first tube body, and the other end is connected to the splicing joint.

[0019] By setting a lifting frame and a guide plate, when the distance-controlled columnar mist switch fire cannon is used, its docking and installation operation can be completed quickly, and at the same time, it can be flexibly applied to external water pipes of different specifications, thereby improving its scope of application; during operation, the user pushes the mobile base so that the mobile base can use two sets of guide plates to guide the connecting female head of the external water pipe to the lower end of the splicing joint, which is convenient for the splicing joint and the docking operation with the external water pipe, and then the lifting frame 41 is driven downward by the lifting rod to dock the splicing joint of the lifting frame with the external water pipe.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Use the main nozzle to form a mist water shield protection structure to the spray tank, which protects the user who controls the fire water monitor head, and use the auxiliary nozzle to inject water into the fixed nozzle. The columnar water sprayed by the fixed nozzle can effectively control the fire and play a major role in extinguishing the fire. At the same time, because the auxiliary nozzle and the main nozzle are independently supplied with water, the fixed nozzle will not reduce the water pressure in the main nozzle when used synchronously, so that the mist and columnar water flow are sprayed at high pressure, allowing the user to continuously perform fire extinguishing operations while approaching the fire source, thereby improving the fire extinguishing effect. At the same time, the fire monitor can also realize columnar spray or mist spray alone.

[0022] 2. By setting up a lifting frame and a guide plate, when the fire monitor is used, its docking and installation operation can be completed quickly, and it can be flexibly applied to external water pipes of different specifications, thereby improving its scope of application; during operation, the user pushes the mobile base so that the mobile base can use two sets of guide plates to guide the connecting female head of the external water pipe to the lower end of the splicing joint, which is convenient for the splicing joint and the docking operation with the external water pipe, and then the lifting frame is driven downward by the lifting rod to dock the splicing joint of the lifting frame with the external water pipe.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically limited.

[0031] See also Figure 1 The present embodiment discloses a column mist switching fire cannon, comprising a cannon head 1, a first tube body 2, a second tube body 3 and a mobile base 4, wherein the two ends of the second tube body 3 are respectively connected to the cannon head 1 and the first tube body 3, the water inlet end of the first tube body is installed with a mobile base 4, the first tube body 2 and the second tube body 3 are both provided with a steering gear 5, the steering gear 5 is composed of a gear and a motor, and the steering gear 5 can be used to drive the first tube body 2 and the cannon head 1 to rotate, thereby adjusting the spraying angle of the cannon head 1.

[0032] See also Figure 2 and Figure 3 The gun head 1 includes a main nozzle 11, a telescopic sleeve 12, an auxiliary nozzle 13, a fixed nozzle 14, a branch sleeve 15, a direct current pipe 16, a docking seat 17, a fixed chuck 18 and a valve 19. One end of the main nozzle 11 is connected to the second tube body 3 through the branch sleeve 15, and the outer wall of the other end is movably connected to the telescopic sleeve 12. The auxiliary nozzle 13 is fixed inside the main nozzle 11 through a docking bracket (not marked in the figure). The output end of the auxiliary nozzle 13 extends outward from the telescopic sleeve 12 and is connected to the fixed nozzle 14. The outer side of the fixed nozzle 14 and the inner side of the output end of the telescopic sleeve 12 are both inclined structures, so that a spray groove 101 is formed between the fixed nozzle 14 and the telescopic sleeve 12.

[0033] The water inlet end of the auxiliary nozzle 13 is fixedly installed with a water inlet joint 131, the auxiliary nozzle 13 is provided with a valve 19, the inner side of the branch sleeve 15 is fixedly installed with a docking seat 17, the water inlet joint 131 is connected with the docking seat 17, one end of the direct current pipe 16 passes through the branch sleeve 15 and is connected with the docking seat 17, and the other end is connected with an external water source, the docking seat 17 and the branch sleeve 15 are fixed by two groups of fixed chucks 18, and the fixed chucks 18 are provided with a plurality of through holes 181. Through the setting of the fixed chucks 18 and the through holes 181 on the fixed chucks 18, water can flow between the docking seat 17 and the branch sleeve 15, and the docking seat 17 is assisted in fixing.

[0034] Furthermore, a sloped nozzle 141 is provided inside the fixed nozzle 14, and the output port diameter of the sloped nozzle 141 is smaller than the input port diameter. Specifically, the cross-section of the sloped nozzle 141 is an isosceles trapezoidal structure, so that the fixed nozzle 14 is output-pressurized, ensuring that the water sprayed from the fixed nozzle 14 is columnar.

[0035] Specifically, the valve 19 is opened to control the auxiliary nozzle 13 alone, so that the auxiliary nozzle 13 can directly supply water to the fixed nozzle 14 through the branch sleeve 15. When the spray slot 101 is opened, the main nozzle 11 is used to form a mist water shield protection structure to the spray slot 101, which protects the user who controls the fire water cannon head, and the auxiliary nozzle 13 is used to inject water into the fixed nozzle 14, so that the water is pressurized and ejected from the inclined nozzle 141. The columnar water ejected from the fixed nozzle 14 can effectively control the fire and play a major role in extinguishing the fire. At the same time, because the auxiliary nozzle 13 and the main nozzle 11 are both independently supplied with water, the fixed nozzle 14 will not reduce the water pressure in the main nozzle 11 when used synchronously, so that the spray slot 101 and the inclined nozzle 141 both maintain a good spraying effect, so that the mist and columnar water flow are ejected in a high-pressure state, so that the user can continuously perform fire extinguishing operations while approaching the fire source, thereby improving the fire extinguishing effect.

[0036] See also Figure 1, the main nozzle 11 is connected to the telescopic sleeve 12 through a driving assembly 6, the driving assembly 6 includes a driving motor 61, a screw 62 and a fixing nut 63, the driving motor 61 is fixed to the outer wall of the main nozzle 11, the fixing nut 63 is fixed to the outer wall of the telescopic sleeve 12, one end of the screw 62 is connected to the driving motor 61, and the other end is threadedly connected to the fixing nut 63; specifically, by driving the driving motor 61, the screw 62 is driven to rotate, and since the telescopic sleeve 12 is sleeved on the outer wall of the main nozzle 11, the rotation of the screw 62 will cause the fixing nut 63 to move vertically on the screw 62, thereby driving the telescopic sleeve 12 to slide on the outer wall of the main nozzle 11, so as to adjust the opening and closing size of the spray slot 101, or even close the spray slot 101; specifically, when the spray slot 101 is reduced, the water pressure in the main nozzle 11 increases, and the spray pressure of the main nozzle 11 is increased, so that the water body is sprayed out from the spray slot 101 between the telescopic sleeve 12 and the fixed nozzle 14 in a mist form.

[0037] For further information, see Figure 2 A connecting seat 7 is fixed on the outer wall of the main nozzle 11, a limiting seat 8 is arranged on the telescopic sleeve 12, a guide rod 9 is fixed on the connecting seat 7, and one end of the guide rod 9 away from the connecting seat 7 passes through the limiting seat 8 and is slidably connected with the limiting seat 8.

[0038] For further information, see Figure 4 and Figure 5 The bottom of the mobile base 4 is movably installed with a lifting frame 41 and two sets of guide plates 42. The two sets of guide plates 42 are located on one side of the lifting frame 41. The two sets of guide plates 42 are symmetrically arranged in an inclined shape, specifically in the shape of an "eight"; the two ends of the lifting frame 41 are connected to the bottom of the mobile base 4 through a lifting rod 43, and a telescopic tube 44 is connected to the lifting frame 41. One end of the telescopic tube 44 passes through the mobile base 4 and is connected to the first tube body 2, and the other end is connected to a splicing joint 45. The splicing joint 45 is used to connect the female connector of the external water pipe. Among them, the small-diameter ends of the two sets of guide plates 42 in the shape of an "eight" are arranged toward the bottom direction of the splicing joint 45, so that the female connector of the external water pipe can quickly enter from the large-diameter end of the guide plate 42, and through the positioning of the guide plate 42, the female connector of the external water pipe can quickly dock with the splicing joint 45 from the small-diameter end of the guide plate 42, thereby improving the docking speed between the gun head and the external water pipe, thereby improving the efficiency of fire extinguishing in the later stage.

[0039] Specifically, by setting up the lifting frame 41 and the guide plate 42, when the distance-controlled columnar mist switch fire cannon is used, its docking and installation operation can be quickly completed, and at the same time, it can be flexibly applied to external water pipes of different specifications, thereby improving its scope of application; during operation, the user pushes the mobile base 4, so that the mobile base 4 can use two sets of guide plates 42 to guide the connecting female head of the external water pipe to the lower end of the splicing joint 45, which is convenient for the splicing joint 45 to dock with the external water pipe, and then the lifting frame 41 is driven downward by the lifting rod 43, so that the splicing joint 45 of the lifting frame 41 is docked with the external water pipe.

[0040] Furthermore, the lifting frame 41 is provided with a mounting through hole, the telescopic tube 44 is connected to one end of the mounting through hole, and the splicing joint 45 is threadedly connected to the other end of the mounting through hole. The user can select a splicing joint 26 of corresponding size according to the caliber of the connecting female head, and use the threaded structure to fix the lifting frame 24 and the splicing joint 26. The lifting frame 24 is driven downward by the lifting rod 28, so that the splicing joint 26 of the lifting frame 24 is connected to the drainage structure.

[0041] The working principle of this embodiment is as follows: the valve 19 is opened to control the auxiliary nozzle 13 alone, so that the auxiliary nozzle 13 can directly supply water to the fixed nozzle 14 through the branch sleeve 15. When the spray slot 101 is opened, the main nozzle 11 is used to form a mist water shield protection structure to the spray slot 101, which plays a protective role for the user who controls the fire water monitor head, and the auxiliary nozzle 13 is used to inject water into the fixed nozzle 14, so that the water is pressurized and sprayed out from the inclined nozzle 141. The columnar water sprayed from the fixed nozzle 14 can effectively control the fire and play a major role in extinguishing the fire. At the same time, because the auxiliary nozzle 13 and the main nozzle 11 are both independently supplied with water, the fixed nozzle 14 will not reduce the water pressure in the main nozzle 11 when used synchronously, so that the spray slot 101 and the inclined nozzle 141 both maintain a good spraying effect, so that the mist and columnar water flow are sprayed in a high-pressure state, so that the user can continuously perform fire extinguishing operations while approaching the fire source, thereby improving the fire extinguishing effect.

[0042] It should be noted that the present invention can also realize columnar spray or mist spray alone. When columnar spray alone is needed, the female connector of the external water pipe is removed from the joint 45, and the auxiliary nozzle 13 directly supplies water to the fixed nozzle 14 to form columnar spray fire extinguishing, or the valve 19 is closed, and the drive motor 61 is driven to drive the screw 62 to rotate. Since the telescopic sleeve 12 is sleeved on the outer wall of the main nozzle 11, the rotation of the screw 62 will cause the fixing nut 63 to move vertically on the screw 62, thereby driving the telescopic sleeve 12 to slide on the outer wall of the main nozzle 11, opening the spray slot 101 to the maximum state, and the water sprayed from the spray slot 101 will also be in a large-caliber column. When mist spray alone is needed, the valve 19 is closed, the drive motor 61 is driven, and the telescopic sleeve 12 is driven to slide on the outer wall of the main nozzle 11. When the spray slot 101 is opened to a state where the water source can form a mist, the drive of the drive motor 61 can be stopped, and a mist spray alone is realized.
