[0032] Example 1:
[0033] like Figure 1As shown in Figure 9, this utility model provides a fire hose with hydraulic lighting, including a hose body 1. The hose body 1 includes a water outlet pipe 11 for discharging water, a lighting device 2 disposed on one side of the water outlet pipe 11, and a hydraulic power generation device 3 disposed between the water outlet pipe 11 and the lighting device 2. The lighting device 2 is electrically connected to the hydraulic power generation device 3. The lighting device 2 is rotatably disposed on the outside of the water outlet pipe 11. By rotatably distributing the lighting device 2 on one side of the water outlet pipe 11, i.e., by incorporating the lighting device 2 into the fire hose, the workload of firefighters is reduced, and firefighters can manually adjust the lighting device. The lighting direction of the lighting device 2 described above is designed to facilitate firefighters' better observation of the fire scene and firefighting efforts. Furthermore, to simplify the circuit design of the fire hose and further reduce the burden on firefighters, a hydroelectric power generation device 3 is installed within the fire hose. When the fire hose is used to extinguish a fire, the impact force of the water flow triggers the hydroelectric power generation device 3 to convert the mechanical energy of the water flow into electrical energy, providing a stable power supply for the lighting device 2. This enables efficient use of water resources, improves lighting effects, helps firefighters maintain clear visibility in complex environments, and enhances the safety of the lighting device 2. In addition, the lighting device 2 can use LED lights, etc.
[0034] In some alternative embodiments, the water outlet pipe 11 includes several detachably connected segmented pipe fittings, and the hydroelectric power generation device 3 is located between any of the segmented pipe fittings and the lighting device 2 to facilitate the assembly and disassembly of the hydroelectric power generation device 3.
[0035] Specifically, such as Figure 1 and Figure 2 As shown, a connecting bracket 4 is provided on the outside of the water outlet pipe 11. The lighting device 2 is rotatably mounted on one side of the connecting bracket 4 via a universal adjustment component 5. The hydroelectric power generation device 3 is located between the water outlet pipe 11 and the connecting bracket 4, and supplies power to the lighting device 2 through the hydroelectric power generation device 3. The connecting bracket 4 is provided with a mounting surface 40 for mounting the lighting device 2. The orientation of the mounting surface 40 is consistent with the water outlet direction of the water outlet pipe 11. When the fire hose is used to extinguish the fire, the hydroelectric power generation device 3 is triggered by the impact force of the water flow and supplies power to the lighting device 2 to achieve illumination. At the same time, firefighters can manually adjust the lighting direction of the lighting device 2. Firefighters only need to apply a force directly to the lighting device 2 to make the lighting device 2 rotate relative to the connecting bracket 4 via the universal adjustment component 5, thereby changing the lighting direction of the lighting device 2 to meet the lighting needs of firefighters at different positions and heights during firefighting and search and rescue, and improve the efficiency of firefighting and search and rescue.
[0036] Furthermore, such as Figure 2As shown, the universal adjustment assembly 5 includes a first hinge portion 51 located on one side of the connecting bracket 4 and a second hinge portion 52 located on one side of the lighting device 2. The lighting device 2 is rotatably connected to one side of the connecting bracket 4 by the corresponding hinge of the first hinge portion 51 and the second hinge portion 52. Optionally, the hinge structure between the first hinge portion 51 and the second hinge portion 52 can be a ball joint hinge structure, a universal joint hinge structure, etc., to realize the multi-angle rotation of the lighting device 2 around the universal adjustment assembly 5, thereby meeting the lighting needs of firefighters at different positions and heights during fire fighting and search and rescue.
[0037] In some optional embodiments of the universal adjustment component 5, such as Figure 2 As shown, the first hinge portion 51 includes a hinge cavity located on one side of the connecting bracket 4, and the second hinge portion 52 includes a ball joint rod located on one side of the lighting device 2. The ball joint rod is rotatably disposed within the hinge cavity, and one end of the ball joint rod away from the hinge cavity is connected to the lighting device 2. In this embodiment, the first hinge portion 51 and the second hinge portion 52 are configured as a ball joint universal hinge structure. Furthermore, a sleeve 54 extending towards the water outlet direction is provided on one side of the connecting bracket 4. The hinge cavity is provided within the sleeve 54, and the hinge cavity is recessed from the end face of the sleeve 54 towards the connecting bracket 4. The second hinge portion 52 is configured as a ball joint rod corresponding to the hinge cavity, and a limiting portion for restricting the ball joint rod from disengaging from the hinge cavity is also provided between the ball joint rod and the hinge cavity. The limiting portion can be configured as a constriction located at the port of the hinge cavity. The lighting device 2 is rotated relative to the second hinge portion 52 by the first hinge portion 51 to achieve adjustment of the lighting direction.
[0038] In some other optional embodiments of the universal adjustment component 5, such as Figure 2 As shown, a ball bearing 55 is also provided between the hinge cavity and the ball joint rod. The ball joint rod is provided with a first ball bearing groove 56, and the inner wall of the hinge cavity is provided with a second ball bearing groove 57 corresponding to the first ball bearing groove 56. The ball bearing 55 is disposed in the first ball bearing groove 56 and the second ball bearing groove 57 to improve the rotational flexibility and structural stability between the first hinge part 51 and the second hinge part 52, improve the rotational efficiency of the lighting device 2, and extend the service life of the universal adjustment assembly 5.
[0039] In some alternative embodiments of the universal adjustment assembly 5, the end of the ball joint away from the hinge cavity is fixedly connected to the lighting device 2.
[0040] In some alternative embodiments of the universal adjustment assembly 5, the end of the ball joint away from the hinge cavity is hinged to the lighting device 2 to further improve the rotation range and rotation flexibility of the lighting device 2.
[0041] On the other hand, such as Figure 3 As shown in Figure 7, the specific structure of the hydroelectric power generation device 3 is as follows: the hydroelectric power generation device 3 includes a drive device 31, an induction device 32 electrically connected to the drive device 31, and a power supply component electrically connected to the induction device 32 and the lighting device 2. The drive device 31 and the induction device 32 are located inside the water outlet pipe 11, and the power supply component is located inside the connecting bracket 4. In this embodiment, the sensing device 32 is located inside the water outlet pipe 11, and the driving device 31 is located inside the sensing device 32. The inner side of the driving device 31 is connected to the water outlet pipe 11 to supply water. When the fire hose discharges water for fire extinguishing, the driving device 31 is triggered by the impact force of the water flow to activate the sensing device 32 to supply power to the lighting device 2 and / or the power supply component. For example, the driving device 31 is triggered by the impact force of the water flow to activate the sensing device 32 to directly supply power to the lighting device 2; or, the driving device 31 is triggered by the impact force of the water flow to activate the sensing device 32 to supply power to the power supply component, which then supplies power to the lighting device 2. The power supply component can also be charged. When the fire water tank is not discharging water, the charged power supply component can supply power to the lighting device 2, thereby improving the flexibility of use of the lighting device 2 and enabling it to be put into use at any time to meet the various usage needs of the lighting device 2 in actual fire extinguishing and search and rescue processes.
[0042] As an optional implementation of the power supply component, such as Figure 2As shown, the power supply assembly includes a circuit board, a battery 331, and a switch. The battery 331 is used for charging and supplying power. The circuit board is disposed on the inner wall of the connecting bracket 4. The switch is used to control the opening and closing of the lighting device 2. The battery 331, the switch, the lighting device 2, and the sensing device 32 are electrically connected to the circuit board. The connecting bracket 4 has a mounting cavity for installing the battery 331. The battery 331 is fixedly installed in the mounting cavity, and both ends of the battery 331 are provided with fixing brackets 3311 connected to the connecting bracket 4. A fixed bracket 3311 positions the battery 331 to improve its installation stability. A wiring channel is provided between the water outlet pipe 11, the connecting bracket 4, and the lighting device 2. The wiring channel communicates with the inside of the water outlet pipe 11 and extends into the first hinge portion 51 and the second hinge portion 52, allowing the lighting device 2 to be connected to the circuit board and the sensing component 322 to the circuit board via wires. This forms a closed circuit between the sensing device 32, the power supply component, and the lighting device 2, ensuring the normal operation of the lighting device 2. Optionally, the circuit board can be a conventional integrated circuit board capable of battery charging and power supply. Optionally, the circuit connections between the circuit board, battery 331, switch, lighting device 2, and sensing device 32 are existing technologies.
[0043] As an optional embodiment of the driving device 31, such as Figure 8 and Figure 9 As shown, Figure 8Arrow H in the diagram indicates the water outlet direction; the driving device 31 includes an impeller 311 rotatably disposed within the water outlet pipe 11. The impeller 311 has a plurality of blades 3111 on its inner side, each blade 3111 being evenly distributed circumferentially. Each blade 3111 has a driving surface on one side for withstanding the impact force of the water flow. The driving surface includes a proximal end 31121 connected to the impeller 311 and a distal end 31121 disposed opposite to and away from the proximal end 31121. 1122, a preset included angle is formed between the proximal end 31121 and the distal end 31122, and the proximal end 31121 and the distal end 31122 are connected by an arc-shaped wall 31123; a water flow channel 3110 communicating with the water outlet pipe 11 is provided between each of the blades 3111, and each of the blades 3111 is driven by the impact force of the water flow to rotate the impeller 311 within the water outlet pipe 11; in this embodiment, each of the blades 3111 rotates along the impeller 311. Extending radially toward the center of the impeller 311, each blade 3111 and the impeller 311 together form the water flow channel 3110 to ensure normal water output of the fire hose. The side of each blade 3111 opposite to the water output direction is the driving surface. The proximal end 31121 of the driving surface is the arc-shaped connection side connected to the impeller 311, and the distal end 31122 of the driving surface is the end closest to the center of the impeller 311. The proximal end 31121 has a preset included angle, and the distal end 31122 is connected to the proximal end 31121 by an arc-shaped wall 31123, so that the side of the blade 3111 that is impacted by the water flow forms an arc surface, which facilitates the impact force of the water flow on the blade 3111 to drive the impeller 311 to rotate axially in the water outlet pipe 11, thereby triggering the sensing device 32 to supply power to the lighting device 2 and / or the battery 331, thereby improving the efficiency of hydropower generation.
[0044] Furthermore, such as Figure 3As shown in Figure 7, the sensing device 32 includes a magnet 321 disposed on the outer periphery of the impeller 311 and a sensing component 322 disposed on the inner side of the water outlet pipe 11. The sensing component 322 is fixedly disposed on the inner side of the water outlet pipe 11. Multiple magnets 321 are provided and spaced apart circumferentially along the impeller 311. The sensing component 322 is opposite to each magnet 321, and a rotation gap 323 is provided between the sensing component 322 and each magnet 321 to allow the impeller 311 to rotate, thus ensuring the normal rotation of the impeller 311. In practical applications, each blade 3111 is driven by the impact force of the water flow to rotate the impeller 311 relative to the sensing component 322. The sensing component 322 is electrically connected to the lighting device 2. This allows the sensing component 322 to generate electricity through electromagnetic induction to supply power to the power supply component and / or the lighting device 2, thereby realizing the conversion and transmission of electrical energy between the hydroelectric power generation device 3 and the lighting device 2, ensuring the normal use of the lighting device 2. In some optional embodiments, each magnet 321 can be directly installed on the outer periphery of the impeller 311 by means of bonding, or the outer periphery of the impeller 311 is provided with a plurality of mounting grooves 312 for installing the magnets 321. Each mounting groove 312 is evenly distributed along the axial direction of the impeller 311, and the magnets 321 are correspondingly set with the mounting grooves 312 to improve the installation stability of each magnet 321, thereby improving the stability of the hydroelectric power generation.
[0045] Furthermore, such as Figure 3As shown in Figure 7, the sensing component 322 includes a mounting bracket 3221 disposed inside the water outlet pipe 11 and a coil 3222 disposed in the mounting bracket 3221. The mounting bracket 3221 has a plurality of connecting rods evenly arranged circumferentially, each connecting rod having the coil 3222 wound around it, and each connecting rod having a positioning part at its end. Each positioning part extends circumferentially, and an assembly gap is provided between adjacent positioning parts. In this embodiment, the mounting bracket 3221 is a ring-shaped bracket, and each connecting rod extends radially towards its center along the mounting bracket 3221. Each mounting part has a positioning part at its end away from the outer ring, each positioning part extending circumferentially, and an assembly gap is provided between adjacent positioning parts. The assembly gap can communicate with the water outlet pipe 11, and the coil 3222 is connected through the assembly gap. The coil 3222 provides installation space, allowing production personnel to directly pass the coil 3222 through the assembly gap and wrap it around the outside of the connecting rod. The limiting part positions the coil 3222, preventing it from detaching from the connecting rod, thus improving the installation stability of the coil 3222 and consequently enhancing the structural stability of the sensing component 322. The mounting bracket 3221 has a simple overall structure, is easy to implement, and the coil 3222 is easy to assemble and disassemble, improving the assembly efficiency of the sensing component 322 and reducing the difficulty of assembling and disassembling it. In practical applications, when each blade 3111 is driven by the water flow to rotate the impeller 311, the impeller 311 drives each magnet 321 to rotate relative to each coil 3222, thereby causing the sensing device 32 to generate electromagnetic induction power.
