Description

Technical Field

[0001] This utility model relates to the field of building fire protection equipment, specifically a high-rise building pressurized fire extinguishing device. Background Technology

[0002] Fire extinguishing devices are a general term for equipment used to extinguish or control fires. Based on their extinguishing principles, they can be categorized into physical suppression (such as fire extinguishers and fire hydrants) and chemical suppression (such as gas extinguishing systems). Common forms include portable fire extinguishers, automatic sprinkler systems, and dry powder extinguishing devices. They prevent the spread of fire by isolating oxygen, cooling, or inhibiting combustion reactions, and are widely used in buildings, transportation, and other locations, serving as a crucial guarantee for fire safety.

[0003] High-rise building pressurized fire extinguishing devices are fire-fighting equipment designed for high-rise buildings with insufficient water pressure. They increase the pressure of fire-fighting water through pressurization components, ensuring that fire hydrants and sprinkler systems on each floor of the high-rise building can obtain sufficient water pressure and flow for rapid and effective fire extinguishing. They can be automatically activated in conjunction with the alarm system or operated manually, solving the water supply problem in high-rise buildings and enhancing fire fighting capabilities.

[0004] Existing high-rise building pressurized fire extinguishing devices require firefighters to manually unload long hoses. Firefighters are already physically exhausted from firefighting operations, and having to painstakingly unload these long hoses not only exacerbates their fatigue and prolongs post-operation processing time, but may also affect the efficiency and neatness of unloading due to physical exhaustion, causing inconvenience to subsequent equipment reuse and emergency response preparation.

[0005] Therefore, a high-rise building pressurized fire extinguishing device is proposed to solve the problem that, despite significant physical exertion, people still have to painstakingly manage long and cumbersome fire hoses, which causes inconvenience for subsequent equipment reuse and emergency response preparation. Utility Model Content

[0006] The purpose of this utility model is to provide a high-rise building pressurized fire extinguishing device to solve the problem that in the above-mentioned background technology, after the device is used, firefighters need to manually store long water hoses. Firefighters are already physically exhausted from firefighting operations, and they still have to work hard to organize the long water hoses. This not only aggravates fatigue and prolongs the post-operation processing time, but may also affect the efficiency and neatness of storage due to physical exhaustion, which will cause inconvenience to the subsequent reuse of equipment and emergency response preparation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-rise building pressurized fire extinguishing device, comprising a base plate, a first support frame and a second support frame symmetrically fixedly installed on the top of the base plate, a horizontal shaft symmetrically rotatably arranged on the side of the first support frame and the second support frame that are close to each other, a transmission disc fixedly installed at the end of the two sets of horizontal shafts, a fixing frame fixedly installed on the side of the two sets of transmission discs, a first guardrail fixedly installed at the end of the two sets of fixing frames, a first groove opened on the side of the two sets of first guardrails that are close to each other, a crossbar slidably arranged between the two sets of first guardrails, the two ends of the crossbar sliding in the two sets of first grooves respectively, a second guardrail fixedly installed on the crossbar, and two sets of second guardrails are provided, a second groove opened on the side of the first guardrails that are far from each other, and a fixing component for fixing the crossbar is provided in the two sets of second grooves.

[0008] Preferably, a first fixing block and a second fixing block are fixedly installed on the top of the base plate, and a first transmission rod and a second transmission rod are rotatably installed between the first fixing block and the second fixing block. The first transmission rod is located below the second transmission rod. A first gear is fixedly installed at one end of the first transmission rod, and a first roller is fixedly installed at the other end of the first transmission rod. A second gear is fixedly installed at one end of the second transmission rod, and a second roller is fixedly installed on the other side of the second transmission rod. The first gear and the second gear are meshed and connected.

[0009] Preferably, one end of the first transmission rod passes through the first fixing block and is fixedly installed with a limit block, a motor is detachably installed on the base plate, and the other end of the first transmission rod passes through the second fixing block and is rotatably connected to the end of the motor output shaft.

[0010] Preferably, a first transmission belt and a second transmission belt are respectively fitted on the two sets of horizontal shafts. The end of the first transmission belt away from the horizontal shaft is fitted on the end of the first transmission rod and is located between the limiting block and the first fixing block. The end of the second transmission belt away from the horizontal shaft is fitted on the motor output shaft.

[0011] Preferably, the fixing component includes a first fixing rod, and a through hole adapted to the first fixing rod is opened in the middle of the two sets of first railings. The first fixing rod is slidably disposed in the through hole. A cavity is axially opened inside the crossbar, and the cavity is adapted to the first fixing rod. A second fixing rod is hinged to the end of the first fixing rod. The end of the second fixing rod is slidably disposed in a second groove. A third groove is symmetrically opened on the two side walls of the second groove. A limit rod is detachably installed on the end of the second fixing rod, and the limit rod slides in the third groove.

[0012] Preferably, a pressure tank is detachably installed on the base plate, a pressure gauge is fixedly installed on the top of the pressure tank, a battery is detachably installed inside the outer shell of the pressure tank, and an inlet for connecting to a fire water pipe and an outlet for connecting to a fire hose are fixedly installed on the side of the pressure tank, with the inlet located above the outlet.

[0013] Preferably, the bottom of the base plate is symmetrically and detachably equipped with four sets of casters.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a motor-driven transmission system, the automatic storage function of fire hoses is realized. The motor drives the horizontal shaft, transmission disc and fixing frame to rotate synchronously through the transmission belt, and drives the transmission rod and roller to work together. The long hoses can be wound and stored without the need for manual operation by firefighters, which greatly reduces the physical exertion of firefighters after fire fighting, avoids the problem of low storage efficiency due to physical exhaustion, and significantly shortens the post-operation processing time. The coordinated design of the transmission mechanism ensures the neatness of the hose storage.

[0016] 2. When the horizontal shaft drives the transmission disc to rotate, the fixed frame drives the first and second guardrails to move synchronously. In conjunction with the winding action of the roller, the water hose is kept in an orderly arrangement during the storage process. The fixed component can fix the position of the horizontal bar, and by replacing different horizontal bars, it can flexibly adapt to water hoses of different lengths, which provides convenience for subsequent equipment reuse and emergency response preparation.

[0017] 3. The integrated pressure tank assembly solves the core problem of insufficient water supply pressure in high-rise buildings. The pressure tank is connected to the fire water pipe through the inlet, and after internal pressurization, it provides sufficient pressure to the fire hose from the outlet, ensuring the water pressure and flow requirements of each floor in the high-rise building during fire fighting, and improving the effectiveness of fire fighting; the pressure gauge can monitor the pressure status in real time, which is convenient for operators to make timely adjustments.

[0023] 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.

[0024] Example

[0025] Please see Figure 1 - Figure 4 The illustration shows a high-rise building pressurized fire extinguishing device, including a base plate 11. A first support frame 36 and a second support frame 38 are symmetrically fixedly installed on the top of the base plate 11. A horizontal shaft 33 is symmetrically rotatably mounted on the side of the first support frame 36 and the second support frame 38 closest to each other. A transmission disc 34 is fixedly installed at the end of the horizontal shaft 33. A fixing frame 35 is fixedly installed on the side of the transmission disc 34. A first guardrail 41 is fixedly installed at the end of the fixing frame 35. Two sets of first guardrails 41 have first grooves 43 on opposite sides. A crossbar 44 is slidably disposed at both ends within the two sets of first grooves 43. Two sets of second guardrails 42 are fixedly installed on the crossbar 44. A second groove 53 is provided on the side of the two sets of first guardrails 41 furthest from each other, and a fixing component is disposed within the second groove 53. The rotation of the horizontal shaft 33 drives the movement of the second guardrails 42 to guide the fire hose. The crossbar 44 and the second guardrails 42 cooperate to restrict the position of the fire hose. When the horizontal shaft 33 rotates, the transmission disc 34 drives the first guardrail 41 to rotate through the fixing frame 35. The position of the horizontal bar 44 can be locked by the fixing component to ensure that the water hose does not shift when stored.

[0026] A first fixing block 31 and a second fixing block 32 are fixedly installed on the top of the base plate 11. A first transmission rod 22 and a second transmission rod 28 are rotatably installed between them, with the first transmission rod 22 located below the second transmission rod 28. A first gear 24 is fixedly installed at one end of the first transmission rod 22, and a first roller 26 is fixedly installed at the other end. A second gear 25 is fixedly installed at one end of the second transmission rod 28, and a second roller 27 is fixedly installed at the other end. The first gear 24 and the second gear 25 are meshed together. A limit block 37 is fixedly installed through the first fixing block 31 at one end of the first transmission rod 22. A detachable mounting block is installed on the base plate 11. Equipped with a motor 21, the other end of the first transmission rod 22 passes through the second fixing block 32 and is rotatably connected to the output shaft of the motor 21; a first transmission belt 23 and a second transmission belt 29 are respectively sleeved on the two sets of horizontal shafts 33. The end of the first transmission belt 23 away from the horizontal shaft 33 is sleeved on the end of the first transmission rod 22 and is located between the limiting block 37 and the first fixing block 31. The end of the second transmission belt 29 away from the horizontal shaft 33 is sleeved on the output shaft of the motor 21. Power is transmitted from the first transmission rod 22 and the motor 21 to the horizontal shaft 33 through the transmission belts, realizing the coordinated action of the second guardrail 42, the first roller 26 and the second roller 27. When the motor 21 drives the first transmission rod 22 to rotate, it drives the two sets of horizontal shafts 33 to rotate through the first transmission belt 23 and the second transmission belt 29 respectively. At the same time, the first transmission rod 22 ensures that the two rollers rotate in opposite directions synchronously through the meshing of the first gear 24 and the second gear 25, so that the horizontal bar 44 rotates synchronously with the rollers. This ensures that the second guard plate 42 guides the rollers and that the rotation of the first roller 26 and the second roller 27 is consistent during the storage process, further improving the neatness of the hose storage. At the same time, it presses out the water remaining in the hose, flattens the hose, reduces the weight of the hose, reduces the burden on the device, and extends the life of the device.

[0027] The fixing assembly includes a first fixing rod 51. A through hole 55 adapted to the first fixing rod 51 is opened in the middle of the first panel 41. The first fixing rod 51 is slidably disposed in the through hole 55. A cavity adapted to the first fixing rod 51 is axially opened inside the crossbar 44. A second fixing rod 52 is hinged to the end of the first fixing rod 51 and its end is slidably disposed in the second groove 53. A third groove 54 is opened on the inner walls of both sides of the second groove 53. A limiting rod 56 is detachably installed at the end of the second fixing rod 52. The limiting rod 56 slides in the third groove 54 to ensure the stability of the sliding of the second fixing rod 52. When in use, the second fixing rod 52 is moved, and the limiting rod 56 slides in the third groove 54, so that the first fixing rod 51 can be stably inserted into the cavity of the crossbar 44 through the through hole 55 to complete the position fixation, so that the crossbar 44 will not shake when rotated and stored.

[0028] A pressure tank 13 is detachably mounted on the base plate 11, with a pressure gauge 14 detachably mounted on its top. An inlet 15 for connecting to a fire water pipe and an outlet 16 for connecting to a fire hose are fixedly mounted on its side, with the inlet 15 located above the outlet 16. A battery 17 is detachably mounted inside the outer shell of the pressure tank 13. In this application, the battery 17 is a lithium battery. The battery 17 is directly connected to the booster pump (not shown in the figure) inside the pressure tank 13 via a circuit board, thereby reducing the risk of short circuits by eliminating the external wiring harness. Four sets of movable wheels 12 are symmetrically and detachably mounted on the bottom of the base plate 11. The movable wheels 12 adopt an omnidirectional design and can turn 360°, improving the mobility of the equipment and facilitating rapid transfer to the fire scene to meet the needs of different fire fighting scenarios.

[0029] Working principle:

[0030] Firefighting Operation Phase: Propel the device to the fire scene and connect the fire hose interface to the inlet 15 of the pressure tank 13. Connect one end of the fire hose to the outlet 16 and extend the other end to the floor where the fire originated. Open the valve on the fire hose, and water flows into the pressure tank 13. Power the booster pump (not shown in the figure) through the lithium battery. The booster pump increases the pressure inside the pressure tank 13, thereby increasing the water pressure. The pressure gauge 14 displays the pressure inside the tank in real time, ensuring that the output water pressure meets the firefighting requirements of high-rise buildings. Firefighters use water guns to carry out firefighting operations. The high-pressure water is delivered to the fire point through the hose, achieving effective firefighting.

[0031] Hose storage stage: After the fire extinguishing operation is completed, close the valve and pressure tank 13 on the fire hose, disconnect the hose from the outlet 16, place the crossbar 44 between the first baffles through the second groove 53, move the second fixing rod 52, and slide it in the third groove 54 through the limiting rod 56, so that the first fixing rod 51 can be stably inserted into the cavity of the crossbar 44 through the through hole 55, thus completing the position fixation; start the motor 21, and the motor 21 drives the first transmission rod 22 to rotate through the output shaft: on the one hand, the first transmission rod 22 drives the second gear 25 through the meshing of the first gear 24 and the second gear 25. The transmission rod 28 rotates synchronously in opposite directions, causing the first roller 26 and the second roller 27 to rotate in opposite directions, forming a traction force on the water hose. At the same time, it pushes out the water hose and flattens the water hose, which can reduce the weight of the water hose, reduce the burden on the device, and extend the service life of the device. On the other hand, the output shaft of the motor 21 drives a set of horizontal shafts 33 to rotate through the second transmission belt 29. The first transmission rod 22 drives another set of horizontal shafts 33 to rotate through the first transmission belt 23. The two sets of horizontal shafts 33 rotate synchronously and drive the transmission disc 34 to rotate. The transmission disc 34 drives the first guardrail 41 and the second guardrail 42 to make circular motion through the fixed frame 35. Under the traction of the roller and the guidance of the second guardrail 42, the fire hose is orderly wound around the crossbar 44. After the hose is stored, the opening of the first groove 43 is adjusted to face the bottom plate 11. Then, the second fixing rod 52 is moved so that the limiting rod 56 slides in the third groove 54, causing the first fixing rod 51 to be pulled out of the cavity of the crossbar 44. At this time, the crossbar 44 pulls the stored hose onto the bottom plate 11. A replacement crossbar 44 can then be installed, and the above operation can be repeated to complete the storage of the remaining hose. Through the cooperation of the first groove 43 and the crossbar 44, firefighters can easily remove the stored hose from the device and quickly store the remaining hose, reducing physical exertion and increasing work efficiency.
