Description

Technical Field

[0001] This application relates to the field of fire extinguishing equipment technology, and in particular to an indoor fire extinguishing device. Background Technology

[0002] Indoor fire protection systems refer to facilities and systems installed indoors to extinguish fires that begin in the early stages within a building. They mainly include indoor fire hydrant systems, automatic sprinkler systems, water mist extinguishing systems, foam extinguishing systems, carbon dioxide extinguishing systems, halon extinguishing systems, and dry powder extinguishing systems. According to fire statistics, installing indoor fire protection systems is an effective and necessary safety measure.

[0003] In factory fire protection engineering, wheeled fire extinguishers are generally used. Wheeled fire extinguishers usually have a large capacity and can provide more extinguishing agent, so they are suitable for dealing with large-scale fires. Since factories usually have a large area and various types of materials, they need to have strong fire extinguishing capabilities. When using them, qualified operators are required to operate them, quickly push the fire extinguisher to the fire scene, and then spray the extinguishing agent to achieve the fire extinguishing effect.

[0004] In practical use, existing wheeled fire extinguishing devices generally require manual reversal. Operators need to flexibly adjust the direction of the wheel according to the location and changes in the fire intensity to spray the extinguishing agent to the optimal location of the fire. However, wheeled fire extinguishing devices are relatively heavy, and after prolonged use, operators may become fatigued, making it inconvenient to manually reverse the direction of the wheel. In addition, fatigue may also affect the operator's alertness and judgment, leading to operational errors or safety risks. Summary of the Invention

[0005] The purpose of this application is to provide an indoor fire extinguishing device to address the problem that operators may become fatigued after prolonged use, making it inconvenient to manually turn the trolley.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An indoor fire extinguishing device includes a base plate with rollers installed at its four bottom corners. A horizontal plate is fixedly connected to one side of the base plate, a handle is fixedly connected to the top of the horizontal plate, a control panel is fixedly connected to the top of the handle, several vertical rods are fixedly connected to the top of the base plate, a mixing tank is fixedly connected to the top of the vertical rods, a water outlet pipe is fixedly connected to one side of the mixing tank, a mounting block is fixedly connected to the top of the mixing tank, a belt roller is rotatably connected to the top of the mounting block, a fixing block is fixedly connected to the top of the belt roller, a rotating seat is fixedly connected to the top of the fixing block, a high-pressure water gun is rotatably connected inside the rotating seat, a booster pump is fixedly connected to one end of the high-pressure water gun, a connecting pipe is fixedly connected to the end of the booster pump away from the high-pressure water gun, the connecting pipe is connected to the water outlet, an adjustment mechanism is provided at the top of the horizontal plate, and a dispensing mechanism is provided inside the mixing tank.

[0008] By adopting the above technical solution, when fire needs to be extinguished, first use the handle to drive the base plate to move. The base plate is moved by the bottom rollers. A mixing box is set on the top of the base plate, and the mixing box contains water. After moving to a suitable position, connect the connecting pipe and the water outlet, and then aim the high-pressure water gun at the fire source to extinguish the fire.

[0009] Furthermore, the adjustment mechanism includes a housing fixedly connected to the top of the horizontal plate. A rotary motor is fixedly connected inside the housing. The output shaft of the rotary motor passes through the housing and is fixedly connected to a drive rod. A second belt roller is fixedly connected to the top of the drive rod. A transmission belt is sleeved on the outer surface of the second belt roller. The end of the rotating belt away from the second belt roller is sleeved on the outer surface of the first belt roller. A lifting assembly is provided on the top of the mounting block.

[0010] By adopting the above technical solution, the rotary motor is started, which drives the drive rod to rotate. The rotation of the drive rod drives the second belt roller to rotate, which in turn drives the transmission belt to move. The transmission belt drives the first belt roller to rotate, and the rotation of the first belt roller drives the high-pressure water gun to rotate.

[0011] Furthermore, the lifting assembly includes a slide groove 1 formed on the top of the mounting block, a slider 1 is provided inside the slide groove 1, an electric telescopic rod is fixedly connected to the top of the slider 1, and the top of the electric telescopic rod is rotatably connected to the high-pressure water gun.

[0012] By adopting the above technical solution, the electric telescopic rod can be extended and retracted using the control panel, thereby driving the high-pressure water gun to rotate inside the rotating base, which facilitates the extinguishing of fire sources at both high and low locations.

[0013] Furthermore, the dispensing mechanism includes a dispensing box fixedly connected to the inner wall of the mixing box, a movable block slidably connected to the inner bottom wall of the dispensing box, a dispensing port opened on one side of the dispensing box, the dispensing port penetrating the mixing box, a sealing block fixedly connected to one side of the bottom of the movable block, a through hole opened on one side of the bottom of the dispensing box, the sealing block slidably connected to the through hole, and a driving assembly provided on the outer surface of the driving rod.

[0014] By adopting the above technical solution, the moving block is driven by the driving component, and the moving block moves the sealing block, causing the sealing block to disengage from the through hole, so that the flame retardant can be fully dissolved in the water to form a mixed fire extinguishing agent.

[0015] Furthermore, the bottom of the medicine dispensing box is provided with two sliding grooves, and the bottom of the movable block is fixedly connected with two sliders. The sliders match the sliding grooves and are slidably connected to the sliding grooves.

[0016] By adopting the above technical solution, the slider two and the slide groove two are slidably connected, and the slider two and the slide groove two provide a guiding function for the moving block, making the movement of the moving block more stable.

[0017] Furthermore, the drive assembly includes a bevel gear one fixedly connected to the outer surface of the drive rod, a bevel gear two meshing with one side of the bevel gear one, a rotating rod fixedly connected to one end of the bevel gear two, the end of the rotating rod near the mixing box penetrating the mixing box and rotatably connected to the inner wall of the mixing box, an abutment plate fixedly connected to the outer surface of the rotating rod, a rotating seat two fixedly connected to the top of the moving block, an abutment rod rotatably connected inside the rotating seat two, the top end of the abutment rod penetrating out of the medicine box and fixedly connected to a pulley, and the pulley abutting against the abutment plate.

[0018] By adopting the above technical solution, by adjusting the angle of the high-pressure water gun, the drive rod rotates, causing bevel gear one to rotate. Bevel gear one and bevel gear two mesh and are connected, causing bevel gear two to rotate. The rotation of bevel gear two will in turn drive the rotating rod to rotate. The rotation of the rotating rod will drive the contact plate to move. When the contact plate moves, it will squeeze the pulley. Under the continuous pressure of the contact plate, the pulley will slide on the outer surface of the contact plate. Then the pulley will transmit the pressure to the contact rod, causing the contact rod to transmit the force to the moving block. After being subjected to force, the moving block will slide on the inner bottom wall of the medicine tank.

[0019] Furthermore, springs are fixedly connected to the two sides of the movable block away from the sealing block, and the springs are fixedly connected to the inner wall of the medicine dispensing box. Sealing plates are fixedly connected to the upper and lower sides of the sealing block, and the sealing plates abut against the inner wall of the medicine dispensing box.

[0020] By adopting the above technical solution, the moving block will abut against the spring when it moves, causing the spring to be compressed and generate elastic potential energy. When adjusted to another angle, the elastic potential energy of the spring is released, causing the sealing plate to firmly abut against the inner wall of the medicine box, reducing the risk of flame retardant seeping out from the connection between the sealing block and the through hole.

[0021] Furthermore, several stirring rods are fixedly connected at equal intervals on both sides of the rotating rod.

[0022] By adopting the above technical solutions, the uniformity of the extinguishing liquid is increased, enabling it to extinguish the fire source more effectively during the firefighting process.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the angle of the high-pressure water gun needs to be adjusted, a rotary motor is started. The rotary motor drives the drive rod to rotate, which in turn drives the second belt roller to rotate. The rotation of the second belt roller drives the transmission belt to move, which in turn drives the first belt roller to rotate. The rotation of the first belt roller, in turn, rotates the high-pressure water gun. This allows firefighters to more easily control the direction of the high-pressure water gun, improving the flexibility and accuracy of firefighting. Simultaneously, when extinguishing fires at high or side locations, the electric telescopic rod is activated using the control panel to extend or retract, thereby causing the high-pressure water gun to rotate inside the rotating base, facilitating the extinguishing of fires at both high and low locations. This design improves fire extinguishing performance. Simultaneously, adjusting the angle of the high-pressure water gun causes the drive rod to rotate, which in turn rotates bevel gear one. Bevel gear one and bevel gear two mesh, causing bevel gear two to drive a rotating rod. This rotating rod then moves the contact plate, which presses against a pulley. Under continuous pressure, the pulley slides on the outer surface of the contact plate, transferring pressure to the contact rod. The contact rod then transfers force to the moving block, which slides against the inner bottom wall of the discharge tank. This allows the sealing block to disengage from the through-hole when the high-pressure water gun is adjusted, enabling the internal flame retardant to mix with the water, thus improving fire extinguishing efficiency.

[0025] 2. In this application, when the moving block moves, it will squeeze the spring, causing the spring to be compressed and generate elastic potential energy. When adjusted to another angle, the elastic potential energy of the spring is released. At this time, the flame retardant has come into contact with and mixed with the water source. The reaction force of the spring pushes the moving block to move towards the through hole. When the moving block moves, it drives the sealing plate to firmly abut against the inner wall of the dispensing tank, reducing the risk of flame retardant seeping out from the connection between the sealing block and the through hole. Then, after use, the flame retardant is added into the interior of the dispensing tank from the inlet for easy use next time.

[0026] 3. In this application, while the dispensing mechanism is working, the rotating rod will drive the stirring rod to move inside the mixing box, thereby making the flame retardant and water source mix more quickly and evenly, resulting in higher fire extinguishing efficiency.

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses an indoor fire extinguishing device.

[0037] Reference Figure 1 and Figure 2An indoor fire extinguishing device includes a base plate 1, with rollers 2 installed at the four corners of the bottom of the base plate 1. A horizontal plate 3 is fixedly connected to one side of the base plate 1, a handle 4 is fixedly connected to the top of the horizontal plate 3, a control panel 5 is fixedly connected to the top of the handle 4, several vertical rods 6 are fixedly connected to the top of the base plate 1, a mixing tank 7 is fixedly connected to the top of the vertical rods 6, a water outlet pipe is fixedly connected to one side of the mixing tank 7, an installation block 9 is fixedly connected to the top of the installation block 9, a belt roller 10 is rotatably connected to the top of the belt roller 10, a fixing block 11 is fixedly connected to the top of the fixing block 11, a rotating seat 12 is fixedly connected to the top of the rotating seat 12, a high-pressure water gun 13 is rotatably connected inside the rotating seat 12, a booster pump 14 is fixedly connected to one end of the high-pressure water gun 13, a connecting pipe 15 is fixedly connected to the end of the booster pump 14 away from the high-pressure water gun 13, the connecting pipe 15 is connected to the water outlet 8, an adjustment mechanism is provided on the top of the horizontal plate 3, and a dispensing mechanism is provided inside the mixing tank 7.

[0038] When firefighting is required, first use handle 4 to drive the base plate 1 to move. The base plate 1 is moved using the bottom rollers 2. A mixing tank 7 is installed on the top of the base plate 1, which contains water. After moving to a suitable position, connect the connecting pipe 15 and the water outlet 8, and then aim the high-pressure water gun 13 at the fire source to extinguish the fire. Next, use the control panel 5 to control the adjustment mechanism to move. The adjustment mechanism drives the high-pressure water gun 13 to adjust its angle. By adjusting the angle, the angle of the high-pressure water gun 13 can be controlled through the adjustment mechanism on the control panel 5 to adapt to the needs of different fire scenarios. This allows for precise aiming at the fire source and effective spraying of water to the fire scene. When the high-pressure water gun 13 moves, it will drive the dispensing mechanism to move as well. When the dispensing mechanism moves, it will release the flame retardant inside the dispensing mechanism into the mixing tank 7, so that the flame retardant can be promptly added to the water tank during use, providing a better fire extinguishing effect and ensuring the performance and effectiveness of the flame retardant.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The adjustment mechanism includes a housing 16 fixedly connected to the top of the horizontal plate 3. A rotary motor 17 is fixedly connected inside the housing 16. The output shaft of the rotary motor 17 passes through the housing 16 and is fixedly connected to a drive rod 18. A second belt roller 19 is fixedly connected to the top of the drive rod 18. A transmission belt 20 is sleeved on the outer surface of the second belt roller 19. The end of the rotating belt away from the second belt roller 19 is sleeved on the outer surface of the first belt roller 10. A lifting assembly is provided on the top of the mounting block 9.

[0040] When the angle of the high-pressure water gun 13 needs to be adjusted, the rotary motor 17 is started. The rotary motor 17 drives the drive rod 18 to rotate, the rotating rod 26 rotates, and the belt roller 19 rotates. The belt roller 19 rotates, and the transmission belt 20 moves, which in turn drives the belt roller 10 to rotate. The rotation of the belt roller 10 changes the angle of the high-pressure water gun 13, making it easier to change the angle of the high-pressure water gun 13. This allows for quick responses to fire sources from different directions, improving the efficiency and accuracy of firefighting operations and enabling firefighters to better cope with fires in different scenarios.

[0041] Reference Figure 2 and Figure 3 The lifting assembly includes a slide groove 21 on the top of the mounting block 9, a slider 22 inside the slide groove 21, an electric telescopic rod 23 fixedly connected to the top of the slider 22, and the top of the electric telescopic rod 23 rotatably connected to the high-pressure water gun 13.

[0042] When extinguishing fires at high or side locations, first, follow the steps above to align the high-pressure water gun 13 with the fire source at the same horizontal level. As the high-pressure water gun 13 moves, it will cause the slider to slide inside the groove, providing additional support points and making the adjustment of the high-pressure water gun 13 more stable. Then, when adjusting the height of the high-pressure water gun 13, use the control panel 5 to activate the electric telescopic rod 23 to extend and retract, thereby causing the high-pressure water gun 13 to rotate inside the rotating seat 12. This facilitates the extinguishing of fires at both high and low locations, further enhancing adaptability and improving fire extinguishing performance.

[0043] Reference Figure 4 , Figure 5 and Figure 6 The dispensing mechanism includes a dispensing box 28 fixedly connected to the inner wall of the mixing box 7. A moving block 29 is slidably connected to the inner bottom wall of the dispensing box 28. A dispensing port 32 is opened on one side of the dispensing box 28, and the dispensing port 32 penetrates the mixing box 7. A sealing block 30 is fixedly connected to one side of the bottom of the moving block 29. A through hole 31 is opened on one side of the bottom of the dispensing box 28. The sealing block 30 is slidably connected to the through hole 31. A driving component is provided on the outer surface of the driving rod 18.

[0044] When flame retardant needs to be added to the mixing tank 7, the moving block 29 is moved by the driving component. The moving block 29 moves the sealing block 30, causing the sealing block 30 to disengage from the through hole 31. This allows the flame retardant to fully dissolve in the water, forming a mixed extinguishing agent. The flame retardant and the mixed water are then sprayed out by the high-pressure water gun 13 and sprayed directly onto the fire source. The mixed extinguishing agent can more effectively suppress combustion and improve the fire extinguishing effect when sprayed.

[0045] Reference Figure 5 and Figure 6 The bottom of the medicine box 28 is provided with two sliding grooves 39 on both sides. The bottom of the movable block 29 is fixedly connected with two sliders 39. The sliders 39 match the sliding grooves 39 and are slidably connected to each other.

[0046] When the movable block 29 slides, it is slidably connected by the second slider and the second groove 39. The second slider and the second groove 39 provide guidance for the movable block 29, making the movement of the movable block 29 more stable.

[0047] Reference Figure 2 , Figure 4 and Figure 6 The drive assembly includes a bevel gear 24 fixedly connected to the outer surface of the drive rod 18. A bevel gear 25 is meshed with one side of the bevel gear 24. A rotating rod 26 is fixedly connected to one end of the bevel gear 25. The end of the rotating rod 26 near the mixing box 7 passes through the mixing box 7 and is rotatably connected to the inner wall of the mixing box 7. An abutment plate 36 is fixedly connected to the outer surface of the rotating rod 26. A rotating seat 33 is fixedly connected to the top of the moving block 29. An abutment rod 34 is rotatably connected inside the rotating seat 33. The top end of the abutment rod 34 passes through the medicine box 28 and is fixedly connected to a pulley 35. The pulley 35 abuts against the abutment plate 36.

[0048] When the moving block 29 moves, the angle of the high-pressure water gun 13 is adjusted, causing the drive rod 18 to rotate and drive the bevel gear 24 to rotate. The bevel gear 24 and the bevel gear 25 mesh and rotate, which in turn drives the rotating rod 26 to rotate. The rotating rod 26 then drives the contact plate 36 to move. When the contact plate 36 moves, it presses against the pulley 35. Under the continuous pressure of the contact plate 36, the pulley 35 slides on the outer surface of the contact plate 36. Then the pulley 35 transmits the pressure to the contact rod 34, which in turn transmits the force to the moving block 29. After being forced, the moving block 29 slides on the inner bottom wall of the medicine tank 28. Thus, when the angle of the high-pressure water gun 13 is adjusted, the sealing block 30 can be disengaged from the through hole 31, allowing the flame retardant inside to come into contact with and mix with the water.

[0049] Reference Figure 5 and Figure 6 Springs 37 are fixedly connected to the two sides of the movable block 29 away from the sealing block 30. The springs 37 are fixedly connected to the inner wall of the medicine dispensing box 28. Sealing plates 38 are fixedly connected to the upper and lower sides of the sealing block 30. The sealing plates 38 abut against the inner wall of the medicine dispensing box 28.

[0050] When the movable block 29 moves, it will contact the spring 37, causing the spring 37 to be compressed and generate elastic potential energy. When adjusted to another angle, the elastic potential energy of the spring 37 is released. At this time, the flame retardant has come into contact with and mixed with the water source. The reaction force of the spring 37 pushes the movable block 29 to move towards the through hole 31. When the movable block 29 moves, it drives the sealing plate 38 to firmly abut against the inner wall of the dispensing tank 28, reducing the risk of flame retardant seeping out from the connection between the sealing block 30 and the through hole 31. Then, after use, the flame retardant is added into the interior of the dispensing tank 28 from the inlet 32 ​​for the next use.

[0051] Reference Figure 4 Several stirring rods 27 are fixedly connected at equal intervals on both sides of the rotating rod 26.

[0052] While the dispensing mechanism is working, the rotating rod 26 will drive the stirring rod 27 to move inside the mixing box 7, thereby making the flame retardant and water mix more quickly and evenly, resulting in higher fire extinguishing efficiency.

[0053] Working principle: When fire needs to be extinguished, first use handle 4 to drive the base plate 1 to move. The base plate 1 is moved by the bottom rollers 2. The mixing box 7 is set on the top of the base plate 1. The mixing box 7 contains water. After moving to a suitable position, connect the connecting pipe 15 and the water outlet 8. Then aim the high-pressure water gun 13 at the fire source to extinguish the fire. Start the rotary motor 17. The rotary motor 17 drives the drive rod 18 to rotate. The rotating rod 26 rotates and drives the belt roller 19 to rotate. The belt roller 19 rotates and drives the transmission belt 20 to move. The transmission belt 20 drives the belt roller 10 to rotate. The rotation of the belt roller 10 causes the high-pressure water gun 13 to rotate. The control panel 5 can also be used to start the electric telescopic rod 23 to extend and retract, thereby driving the high-pressure water gun 13 to rotate inside the rotating seat 12, which makes it easier to extinguish fire sources at high and low places.

[0054] By adjusting the angle of the high-pressure water gun 13, the drive rod 18 rotates, causing the first bevel gear 24 to rotate. The first bevel gear 24 and the second bevel gear 25 mesh, causing the second bevel gear 25 to rotate. The rotation of the second bevel gear 25 in turn causes the rotating rod 26 to rotate. The rotation of the rotating rod 26 causes the contact plate 36 to move. When the contact plate 36 moves, it will squeeze the pulley 35. Under the continuous pressure of the contact plate 36, the pulley 35 will slide on the outer surface of the contact plate 36. Then the pulley 35 transmits the pressure to the contact rod 34, causing the contact rod 34 to transmit the force to the moving block 29. After being subjected to force, the moving block 29 slides on the inner bottom wall of the discharge tank 28. Thus, when the angle of the high-pressure water gun 13 is adjusted, the sealing block 30 can be disengaged from the through hole 31, allowing the internal flame retardant to come into contact with and mix with the water, thereby improving the fire extinguishing efficiency.
