Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a pressurized water supply device for high-rise buildings. Background Technique

[0002] In recent years, there have been more and more high-rise residential buildings in cities, and more and more people choose to live in high-rise apartments. However, the higher the building, the greater the fire risk. Therefore, the residents of high-rise buildings should have necessary fire-fighting knowledge and always keep the fire safety string tight. Only in this way can unnecessary casualties and losses be avoided in case of a fire.

[0003] At present, for high-rise buildings, fire hydrants are always the first choice for initial fire fighting. The initial small fire is the easiest to extinguish. However, in current life, due to insufficient water pressure in high-rise buildings, the pressure of the fire-fighting water column is small or even unable to spray out, resulting in the situation that the fire cannot be extinguished and losses cannot be stopped in time, thus affecting the lives and property safety of residents. Therefore, we propose a pressurized water supply device for high-rise buildings. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pressurized water supply device for high-rise buildings, which has the advantage of good pressurization effect, and solves the problem that in current life, due to insufficient water pressure in high-rise buildings, the pressure of the fire-fighting water column is small or even unable to spray out, resulting in the situation that the fire cannot be extinguished and losses cannot be stopped in time, thus affecting the lives and property safety of residents.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A pressurized water supply device for high-rise buildings, including a bottom plate. The right end of the top of the bottom plate is fixedly installed with a pneumatic tank. The left end of the top of the bottom plate is fixedly installed with an inverted J-shaped fixing plate and a driving motor. The output end of the driving motor is fixedly connected with a driving gear. The rear side of the driving gear is fixedly connected with a guiding pin rod. The middle end of the top of the bottom plate is fixedly connected with a pressurizing cylinder. The left end of the inner cavity of the pressurizing cylinder is movably connected with a piston. The middle end of the left side of the piston is fixedly connected with a pulling rod. The left side of the pulling rod is fixedly connected with a movable plate adapted to the guiding pin rod. The middle end of the top of the pneumatic tank is communicated with a water inlet pipe with a first solenoid valve arranged on the inner surface of the lower end. The upper end of the water inlet pipe is communicated with a water guide pipe. The end of the water guide pipe far away from the water inlet pipe is communicated with the right end of the top of the pressurizing cylinder. A second solenoid valve and a first one-way valve are respectively arranged at the upper and lower ends of the water guide pipe. A pressurizing water pipe is communicated between the right side of the pressurizing cylinder and the upper end of the pneumatic tank. A second one-way valve is arranged at the lower end of the pressurizing water pipe.

[0006] Preferably, the lower end at the rear side of the pressure tank is communicated with a pressurizing cylinder. The middle part at the rear side of the pressurizing cylinder is movably connected with a rotating rod through a bearing, and the rear end of the rotating rod extends into the inner cavity of the pressurizing cylinder. A pressurizing delivery impeller is fixedly connected to the outer surface of the rotating rod located in the inner cavity of the pressurizing cylinder, and a driven sprocket is fixedly connected to the rear side of the rotating rod.

[0007] Preferably, the upper end of the inverted J-shaped fixing plate is movably connected with a rotating shaft through a bearing. A driven gear meshing with the driving gear is fixedly connected to the front surface of the rotating shaft, a driving sprocket is fixedly connected to the rear side of the rotating shaft, and a chain is sleeved on the outer sides of the driving sprocket and the driven sprocket.

[0008] Preferably, the lower end at the rear side of the pressurizing cylinder is communicated with a drain pipe with a manual valve body arranged on its inner surface.

[0009] Preferably, a water pressure gauge is arranged at the upper end at the rear side of the pressure tank.

[0010] Preferably, guide rods sliding on the inner surface of the pressurizing cylinder are fixedly connected to the upper and lower ends on the right side of the movable plate and the left side of the piston.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the arrangement of the water inlet pipe and the first solenoid valve, the present utility model can normally deliver water into the pressure tank. When pressurization is required in an emergency, the external controller closes the first solenoid valve and then opens the second solenoid valve and the driving motor. Then, the water body can enter the pressurizing cylinder through the water guide pipe and the first check valve. At this time, the driving motor can drive the driving gear to rotate. When the driving gear rotates, it can drive the guide pin rod to slide on the inner surface of the movable plate. Then, as the driving gear rotates, the movable plate can drive the piston to move left and right in the pressurizing cylinder through the pull rod. When the movable plate drives the piston to move left in the pressurizing cylinder through the pull rod, with the assistance of the first check valve, a sufficient amount of water body can be quickly sucked into the right end of the inner cavity of the pressurizing cylinder through the water guide pipe. When the movable plate drives the piston to move right in the pressurizing cylinder through the pull rod, with the assistance of the second check valve, the water body that has just been quickly sucked into the pressurizing cylinder can be pressurized and pushed to the right end of the inner cavity of the pressurizing cylinder. The pressurized water body can quickly enter the pressure tank through the pressurizing water pipe and the second check valve, increasing the pressure in the pressure tank, thereby enabling the device to achieve the purpose of pressurization.

[0013] 2. By providing an inverted J-shaped fixing plate, when the driving gear rotates, the driven gear engaged with it can drive the rotating shaft and the driving sprocket to rotate. With the assistance of the chain and the driven sprocket, the pressurizing and conveying impeller is driven to rotate in the pressurizing cylinder through the rotating rod. As a result, the water in the pressure tank can be pressurized and enter the pressurizing cylinder. When the firefighter connects the fire hose to the drain pipe and opens the manual valve body, the device can provide water with sufficient pressure. With the pressurizing setting of the pressurizing cylinder, the device has the ability of double pressurization, meeting the usage requirements of fire fighting pressurization.
