Description

Technical Field

[0001] This utility model relates to the technical field of fire-fighting equipment, and in particular to a visual fire hose with angle adjustment. Background Technology

[0002] Fire scenes are urgent and unpredictable, requiring firefighters to quickly adjust the spray angle of fire hoses to address fires in different locations. However, existing fire hoses can only be manually adjusted, necessitating firefighters to approach the hose and manipulate it by rotating or turning it. This time-consuming adjustment can delay optimal firefighting opportunities and reduce firefighting efficiency. Furthermore, fire scenes present multiple dangers such as high temperatures, dense smoke, toxic gases, and building collapses, increasing firefighters' exposure risk and physical exertion through manual adjustment. In addition, manual adjustment often relies on firefighters' experience and feel, making precise angle control difficult. In complex fire scenarios, such as accurately spraying water to specific locations within a building or avoiding critical equipment and structures, manual adjustment may not achieve the desired accuracy, impacting firefighting effectiveness.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] This invention addresses the problems mentioned above, such as the existing fire hoses only allowing manual adjustment of the spray angle, which reduces fire extinguishing efficiency, increases firefighters' exposure risk and physical exertion, and the fact that manual adjustment of the spray angle often relies on firefighters' experience and feel, making it difficult to achieve very precise angle control and thus affecting the fire extinguishing effect. The invention proposes a visual fire hose with angle adjustment.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A visual fire hose with adjustable angle includes a hose body, a nozzle assembly at the outlet end of the hose body, the hose body and the nozzle assembly being connected for water discharge, a first rotating connection structure and a driving device being provided between the hose body and the nozzle assembly, and a visual device being provided on one side of the nozzle assembly. The driving device drives the nozzle assembly to rotate relative to the hose body around the first rotating connection structure, and the nozzle assembly drives the visual device to rotate synchronously.

The driving device includes a drive motor disposed on one side of the mounting seat and a transmission component connected to the drive motor. The drive motor drives the transmission component to generate transmission, and the transmission component drives the first connecting seat to rotate relative to the hose body around the first rotating connecting structure.

[0008] As described above, the visual fire hose with angle adjustment includes a transmission component comprising a first transmission component connected to the drive motor and a second transmission component connected to the first transmission component. The second transmission component is located on the outer periphery of the hose body. The drive motor drives the first transmission component to rotate, causing the first transmission component to rotate circumferentially around the second transmission component, thereby driving the first connecting seat to rotate relative to the hose body around the first rotating connection structure.

[0009] As described above, the visual fire hose with angle adjustment has a first mating surface on the peripheral wall of the first transmission component and a second mating surface on the peripheral wall of the second transmission component, and the first mating surface and the second mating surface are engaged and connected.

[0010] As described above, the visual fire hose with angle adjustment has a first transmission component with a connecting rod extending toward the drive motor. A fixed bracket is also provided on one side of the drive motor. The fixed bracket has an assembly hole corresponding to the connecting rod. At least part of the connecting rod extends into the assembly hole and is connected to the output shaft of the drive motor. The connecting rod rotates in the assembly hole through the drive motor, thereby driving the first transmission component to rotate.

[0011] As described above, the visual fire hose with angle adjustment has a sleeve at the outlet end of the hose body, a first connector extending toward the hose body on one side of the first connector seat, a first rotating cavity that can accommodate the first connector, and a first rotating connection structure disposed between the first rotating cavity and the first connector.

[0012] As described above, the visual fire hose with angle adjustment is provided with a mounting bracket connected to one side of the nozzle assembly. The mounting bracket has a mounting port adapted to the visual device, and the visual device is fixed in the mounting port.

[0013] As described above, the visual fire hose with angle adjustment has a mounting bracket detachably connected to the outside of the nozzle assembly. The mounting bracket includes a mounting part, a connecting arm located on one side of the mounting part, and a mounting cylinder located at the end of the connecting arm. The mounting cylinder encloses and forms the mounting opening.

[0014] As described above, the visual fire hose with angle adjustment includes a second connecting seat disposed between the nozzle and the first connecting seat. A second rotating connection structure is provided between the first connecting seat and the second connecting seat. The second connecting seat can swing relative to the first connecting seat through the second rotating connection structure to drive the nozzle to swing synchronously, and drive the visual device to swing synchronously through the nozzle.

[0015] As described above, the visual fire hose with angle adjustment has a second connector at the outlet end of the first connector, the extension direction of the second connector is perpendicular to the extension direction of the first connector, the second connector has a second rotating cavity corresponding to the second connector, and a second rotating connection structure is provided between the second connector and the second rotating cavity.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The nozzle assembly is driven by a drive device to rotate around the first rotating connection structure to adjust the water spray direction of the nozzle assembly, making it easier for firefighters to extinguish fires at different heights and locations. At the same time, the real-time firefighting situation at the fire scene is captured by a visualization device. The visualization device rotates synchronously with the nozzle assembly to adjust the shooting direction of the visualization device, which helps firefighters inside and outside the fire scene to observe the firefighting situation. This allows firefighters to adjust the water spray angle of the nozzle assembly and the firefighting strategy according to the firefighting situation, thereby improving the firefighting efficiency and effectiveness.

[0030] Example 1:

[0031] like Figure 1As shown in Figure 6, this utility model provides a visual fire hose with angle adjustment, including a hose body 1. The hose body 1 has a nozzle assembly 2 at its outlet end. The hose body 1 and the nozzle assembly 2 are connected for water discharge. A first rotating connection structure 32 and a driving device 31 are provided between the hose body 1 and the nozzle assembly 2. A visual device 4 is also provided on one side of the nozzle assembly 2. The driving device 31 drives the nozzle assembly 2 to rotate relative to the hose body 1 around the first rotating connection structure 32, and the nozzle assembly 2 drives the visual device 4 to rotate synchronously. In this embodiment, the first rotating connection structure 32 is located inside the hose body 1 and the nozzle assembly 2, and the driving device 31 is located outside the hose body 1 and the nozzle assembly 2. On one side, the visualization device 4 is positioned near the water outlet of the nozzle assembly 2. The visualization device 4 is configured as a small or miniature image acquisition device, such as a camera, capable of acquiring and capturing images. The driving device 31 drives the nozzle assembly 2 to rotate around the first rotating connection structure 32 to adjust the water spray direction of the nozzle assembly 2, facilitating firefighters to extinguish fires at different heights and locations. Simultaneously, the visualization device 4 captures the real-time firefighting situation at the fire scene. The visualization device 4 rotates synchronously with the nozzle assembly 2 to adjust the shooting direction of the visualization device 4, which helps firefighters inside and outside the fire scene to observe the firefighting situation. This allows firefighters to adjust the water spray angle and firefighting strategy of the nozzle assembly 2 according to the firefighting situation, improving firefighting efficiency and effectiveness.

[0032] In a preferred embodiment of this utility model, the driving device 31 is electrically controlled, and a controller electrically connected to the driving device 31 can be installed at the grip part 10 of the gun body 1. The visualization device 4 is also remotely connected to an image receiving device 6, which can be a portable mobile device such as a mobile phone or a miniature display screen. During firefighting, firefighters can hold the fire hose through the grip part 10 of the gun body 1 and use the controller to control the driving device 31, so that the nozzle assembly 2 rotates relative to the gun body 1 around the first rotating connection structure 32, and the visualization device 4 rotates synchronously through the nozzle assembly 2, thereby realizing automatic adjustment of the water spray direction and the angle of the visualization device 4; at the same time, through the... The visualization device 4 captures images of the firefighting process and transmits these images to the image receiving device 6 via a wireless communication module. This allows firefighters to observe the firefighting situation in a timely manner and adjust the spray angle and firefighting strategy of the nozzle assembly 2 accordingly. The drive device 31 is electrically controlled, replacing the traditional manual adjustment of the fire hose's spray direction. This avoids firefighters manually adjusting the nozzle assembly 2 at the fire scene, which would prolong the firefighting time, improve firefighting efficiency, and ensure the safety of firefighters and trapped personnel. Furthermore, the electric drive device 31 controls the angle adjustment of the nozzle assembly 2, improving its rotational accuracy and ensuring that the water sprayed from the fire hose accurately targets the fire source, thereby improving firefighting efficiency and effectiveness. It should be noted that the data transmission between the visualization device 4 and the image receiving device 6 is existing technology and will not be described further here.

[0033] In some alternative embodiments, the fire hose reel is equipped with an electronic control module electrically connected to the drive device 31 and the visualization device 4. The visualization device 4 integrates an image acquisition module, a data processing module, and a digital signal processor. The image acquisition module converts the captured image signal (i.e., light signal) into an electrical signal to form raw image data. The data processing module processes the raw image data, including noise reduction, white balance adjustment, color correction, and compression. The digital signal processor converts the raw image data into a format suitable for transmission, such as JPEG or H.264. The visualization device 4 can be connected to an image receiving device 6, such as a mobile phone, computer, or display screen, via a built-in wireless communication module. The image receiving device 6 may be equipped with a remote control module. The remote control module can be mechanical or touchscreen-based, such as a human-computer interaction module that can be remotely controlled via an app or mini-program on a mobile phone. During firefighting, the visualization device 4 captures real-time images of the fire scene, processes the images, and transmits the image data to the image receiving device 6, allowing firefighters to observe the firefighting situation. Firefighters can then control the drive device 31 via the remote control module to adjust the spray angle and shooting angle of the fire hose. This allows firefighters to adjust their firefighting strategies based on the actual situation, and eliminates the need for firefighters to manually adjust the spray direction of the fire hose near dangerous fire sources, high-temperature areas, or areas with dense smoke. This reduces the possibility of burns, smoke inhalation, or injuries from falling building components, ensuring the personal safety of firefighters.

[0034] Specifically, such as Figure 1 As shown in Figure 3, the nozzle assembly 2 includes a nozzle 21 and a first connecting seat 22 disposed between the gun body 1 and the nozzle 21. The nozzle 21 and the first connecting seat 22 communicate with the gun body 1 to supply water. A first rotating connection structure 32 is disposed between the first connecting seat 22 and the gun body 1. A mounting seat 221 is provided on the outside of the first connecting seat 22. The driving device 31 includes a drive motor 311 disposed on one side of the mounting seat 221 and a transmission assembly 312 that is drively connected to the drive motor 311. The transmission assembly 312 is disposed on the outside of the gun body 1. The mounting base 221 extends outward from the first connecting base 22. The drive motor 311 is fixedly mounted on one side of the mounting base 221. The visualization device 4 is located on one side of the nozzle 21. The drive motor 311 drives the transmission component 312 to generate transmission, and the transmission component 312 drives the first connecting base 22 to rotate relative to the gun body 1 around the first rotating connection structure 32. The first connecting base 22 drives the nozzle 21 and the visualization device 4 to rotate synchronously, thereby adjusting the water spray direction of the nozzle 21 and the shooting direction of the visualization device 4.

[0035] More specifically, such as Figure 1 As shown in Figure 3, the outlet end of the gun body 1 is provided with a sleeve 11, and a first connector 222 extending toward the gun body 1 is provided on one side of the first connecting seat 22. The sleeve 11 is provided with a first rotating cavity 111 that can accommodate the first connector 222. The first rotating connection structure 32 is provided between the first rotating cavity 111 and the first connector 222. The sleeve 11 is fixedly installed in the gun body 1. The first connector 222 can rotate in the first rotating cavity 111 through the first rotating connection structure 32 when subjected to force, so as to drive the nozzle 21 and the visualization device 4 to rotate synchronously.

[0036] In some optional embodiments of the first rotating connection structure 32, the first connector 222 is configured as a cylindrical structure, and the first rotating connection structure 32 is configured as a rotating bearing located between the first connector 222 and the inner wall of the first rotating cavity 111, which can both ensure the normal water output of the fire hose and enable the first connecting seat 22 to rotate relative to the sleeve 11.

[0037] In other alternative embodiments of the first rotating connection structure 32, such as Figure 5 As shown, the first rotating connection structure 32 includes a first annular groove 321 disposed on the inner wall of the first rotating cavity 111, a second annular groove 322 disposed on the outer wall of the first connector 222, and a ball (not shown in the figure) disposed between the first annular groove 321 and the second annular groove 322. A plurality of the first annular groove 321 and the second annular groove 322 may be provided. Each first annular groove 321 and the corresponding second annular groove 322 enclose a combination groove adapted to the ball, so as to realize the rotation of the first connector 22 relative to the sleeve 11.

[0038] Preferably, a sealing structure is also provided between the first connector 222 and the sleeve 11 to prevent water leakage; the sealing structure can be configured as a sealing ring seal, a rotary oil seal seal, a spring-assisted seal, etc., to ensure rotation between the first connector 22 and the sleeve 11, while preventing the fire hose from leaking water from the connection between the first connector 22 and the sleeve 11, thus reducing the fire extinguishing efficiency.

[0039] On the other hand, the optional embodiments of the transmission assembly 312 are as follows, such as... Figure 1As shown in Figure 5, the transmission assembly 312 includes a first transmission member 3121 connected to the drive motor 311 and a second transmission member 3122 connected to the first transmission member 3121. The second transmission member 3122 is located on the outer periphery of the gun body 1. The drive motor 311 drives the first transmission member 3121 to rotate, causing the first transmission member 3121 to rotate circumferentially around the second transmission member 3122, thereby driving the first connecting seat 22 to rotate relative to the gun body 1 around the first rotating connection structure 32; further... The first transmission member 3121 has a first mating surface 31211 on its peripheral wall, which extends circumferentially within the first transmission member 3121. The second transmission member 3122 has a second mating surface 31221 on its peripheral wall, which also extends circumferentially within the second transmission member 3122. The first mating surface 31211 and the second mating surface 31221 are engaged in a meshing connection. In this embodiment, the drive motor 311 is fixedly connected to the outside of the first connecting seat 22 via a mounting base 221. The first transmission component 3121 is directly connected to the output shaft 3111 of the drive motor 311. The first transmission component 3121 is preferably a gear, and the second transmission component 3122 is preferably a gear ring with external teeth. The second transmission component 3122 is fixedly sleeved on the outside of the sleeve 11. The first transmission component 3121 and the second transmission component 3122 are meshed together. The rotation of the output shaft 3111 of the drive motor 311 drives the first transmission component 3121 to rotate axially. Simultaneously, meshing transmission occurs between the first mating surface 31211 and the second mating surface 31221, causing the first transmission component 3121 to rotate circumferentially around the second transmission component 3122. This, in turn, drives the drive motor 311 to rotate circumferentially, and the drive motor 311 drives the first connecting seat 22 to rotate synchronously. This allows the first connecting seat 22 to rotate axially relative to the sleeve 11 around the first rotating connection structure 32, and, through the first connecting seat 22, drives the nozzle assembly 2 to rotate axially relative to the gun body 1 around the first rotating connection structure 32 (e.g., ...). Figure 2 The arrow M-M' in the diagram indicates the axial rotation of the first connecting seat 22, thereby achieving the angle adjustment of the nozzle assembly 2; the rotation of the nozzle assembly 2 is achieved through gear transmission, which facilitates the adjustment of the water spray direction of the nozzle assembly 2. The structure is simple, easy to implement, and can also reduce the modification cost of fire hoses.

[0040] On the other hand, in order to improve the connection stability between the first transmission component 3121 and the drive motor 311, such as Figure 1As shown in Figure 5, the first transmission member 3121 is provided with a connecting rod 31212 extending toward the drive motor 311. A fixed bracket 313 is also provided on one side of the drive motor 311. The fixed bracket 313 has an assembly hole 3131 corresponding to the connecting rod 31212. At least a portion of the connecting rod 31212 extends into the assembly hole 3131 and is connected to the output shaft 3111 of the drive motor 311. The connecting rod 31212 rotates within the assembly hole 3131 via the drive motor 311, thereby driving the first transmission member 3121 to rotate. In this embodiment, the fixed bracket 313 is detachably mounted on the front side of the drive motor 311, and the assembly hole 3131 in the fixed bracket 313 corresponds to the output shaft 3111 of the drive motor 311, so that the output shaft 3111 of the drive motor 311 can extend into the assembly hole 3131. Within 131, one end face of the drive motor 311 facing the fixed bracket 313 abuts against the fixed bracket 313, and the fixed bracket 313 and the drive motor 311 are detachably fixedly connected by means of threaded connection, snap-fit, etc. The output shaft 3111 of the drive motor 311 rotates to drive the connecting rod 31212 to rotate axially within the mounting hole 3131, thereby realizing the rotation of the first transmission component 3121. Furthermore, the outer diameter of the connecting rod 31212 is slightly smaller than the inner diameter of the mounting hole 3131, and the connecting rod 31212 has an inner cavity 31213 facing the drive device 31. The inner cavity 31213 is engaged with the output shaft 3111 of the drive motor 311 to improve the connection stability between the first transmission component 3121 and the drive motor 311, and ensure smooth angle adjustment of the nozzle assembly 2.

[0041] On the other hand, in order to reduce the assembly difficulty of the visualization device 4, such as Figure 1 As shown in Figures 4 and 6, the visualization device 4 is connected to one side of the nozzle assembly 2 via a mounting bracket 5. The mounting bracket 5 extends toward one side of the nozzle 21, and has a mounting port 51 adapted to the visualization device 4. The visualization device 4 is fixed within the mounting port 51. Optionally, the visualization device 4 is snapped into the mounting port 51, simplifying the assembly structure of the visualization device 4 in the fire hose and improving the assembly efficiency of the visualization device 4, thus facilitating the disassembly and maintenance of the visualization device 4. To simplify the circuit structure in the fire hose, a battery can be installed in the visualization device 4 to power it, eliminating the need for wire connections. When the battery is depleted, it can be recharged or the battery can be replaced to enable continuous use of the visualization device 4.

[0042] Specifically, in some optional embodiments of the assembly method of the visualization device 4, such as Figure 6 As shown, the mounting bracket 5 is detachably connected to the outside of the nozzle assembly 2. The mounting bracket 5 includes a mounting part 52, a connecting arm 53 disposed on one side of the mounting part 52, and a mounting cylinder 54 disposed at the end of the connecting arm 53. The mounting cylinder 54 surrounds to form the mounting port 51. In this embodiment, the mounting bracket 5 is detachably mounted on the outside of the nozzle 21 and close to the water outlet end of the nozzle 21. The mounting part 52 is threadedly connected to the outside of the nozzle 21.

[0043] In some other alternative embodiments of the assembly method of the visualization device 4, such as Figure 7 As shown in Figure 8, the outer side of the nozzle 21 may be provided with a connecting part 55 for threaded connection with the mounting part 52 to prevent the screw from penetrating the wall of the nozzle 21 and causing water leakage; or the outer side of the nozzle 21 is provided with a connecting part 55, the connecting part 55 and the mounting part 52 are configured with a snap-fit ​​structure, and a snap-fit ​​limiting structure 57 is provided between the connecting part 55 and the mounting part 52, the limiting structure 57 restricts the mounting part 52 from disengaging from the connecting part 55, thereby improving the connection stability of the visualization device 4.

[0044] In some alternative embodiments, the mounting portion 52 may be configured as a snap ring type mounting portion to be fitted onto the outside of the nozzle 21.

[0045] Example 2:

[0046] To further enhance the multi-angle adjustment of the water spray direction of the fire hose, this embodiment 2, based on embodiment 1, has the following implementation method, such as... Figure 1 As shown in Figure 5, Figure 1The arrows L-L' in the diagram indicate the swing direction of the second connecting seat 23. The nozzle assembly 2 also includes a second connecting seat 23 disposed between the nozzle 21 and the first connecting seat 22. A second rotating connection structure 55 is provided between the first connecting seat 22 and the second connecting seat 23. The second connecting seat 23 can swing relative to the first connecting seat 22 through the second rotating connection structure 55, thereby driving the nozzle 21 to swing synchronously, and driving the visualization device 4 to swing synchronously through the nozzle 21. This increases the rotation dimension of the nozzle 21 and enhances the multi-angle adjustment of the spray direction of the nozzle 21, making the fire hose adaptable to more complex fire environments, especially fire extinguishing blind spots formed by hidden corners such as next to cabinets and under beds. It is necessary to adjust the spray direction of the nozzle 21 to deal with different fire points to be extinguished. At the same time, combined with the visualization device 4 to capture the fire extinguishing situation, firefighters can adjust the spray direction of the nozzle 21 and the fire extinguishing strategy according to the fire extinguishing situation, improve fire extinguishing efficiency, and ensure the safety of firefighters and trapped personnel.

[0047] Specifically, such as Figure 1 As shown in Figure 5, the outlet end of the first connecting seat 22 is provided with a second connecting head 223, that is, the two ends of the first connecting seat 22 are respectively provided with the first connecting head 222 and the second connecting head 223. The extension direction of the second connecting head 223 is perpendicular to the extension direction of the first connecting head 222. The second connecting seat 23 is provided with a second rotating cavity 231 corresponding to the second connecting head 223. A second rotating connection structure 55 is provided between the second connecting head 223 and the second rotating cavity 231. In this embodiment, the first connecting head 222 of the first connecting seat 22 is connected to the first rotating connection structure 55. The connecting structure 32 is rotatably disposed in the first rotating cavity 111 of the sleeve 11. The first connector 222 is driven to rotate axially around the first rotating connecting structure 32 in the first rotating cavity 111 by the driving device 31. At the same time, the nozzle 21 can be oscillated relative to the first connecting seat 22 by the second connecting seat 23 around the second rotating connecting structure 55, and an oscillation angle is formed between the second connecting seat 23 and the first connecting seat 22, which further enhances the angle adjustment of the water spray direction and the shooting direction, so as to facilitate firefighters to deal with fires in different locations and improve fire extinguishing efficiency.

[0048] Furthermore, the specific structure of the second rotating connection structure 55 is similar to that of the first rotating connection structure 32, and will not be described in detail here.

[0049] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
