Description

Technical Field

[0001] This application relates to the technical field of fire water supply systems, and particularly to a constant high-pressure fire water supply system suitable for high-rise buildings. Background Art

[0002] A fire water supply system is a temporary water supply facility for fire fighting and rescue, mainly composed of fire pumps, water tanks, water towers, fire hoses, fire guns, etc. It provides necessary water sources for firefighters during a fire to ensure that the fire can be extinguished in a timely manner. The constant high-pressure fire water supply system for high-rise buildings is a fire water supply system that sets a high-position fire water tank in high-rise buildings to ensure that the static water pressure of the most disadvantageous fire hydrant is not lower than the specified value. This system is mainly used in high-rise buildings to ensure that the fire water source can be effectively supplied to all parts of the building during a fire.

[0003] In the patent document with the published publication number CN115569319B, a constant high-pressure fire water supply system suitable for super high-rise buildings and its design method are provided. For super high-rise buildings where it is difficult to achieve constant high-pressure water supply for the entire floor by the self-gravity of the high-position fire water tank, the invention realizes the pressurized water supply of the fire water extinguishing facilities without starting the fire pump during a fire in the high-rise area of the super high-rise building by converting the compressed gas pressure into fire water pressure, and solves the problem of the unreliability of the temporary high-pressure fire water supply system set in the high-rise area of the super high-rise building. The pressurized gas in the driving cylinder of the invention can maintain the static pressure of the fire water extinguishing system in the high-rise area of the super high-rise building without additionally installing a fire pressure stabilizing system. In addition, by using the constant high-pressure fire water supply device of the invention, "using and stopping as needed" of constant-pressure water can be realized without additional reset operations, simplifying the testing and maintenance processes in the later operation process.

[0004] This device provides the power for water pressurization in the pressurized water chamber through a driving cylinder. The principle is that air is used to push the piston transmission rod to make reciprocating motions, pumping the high-position fire water tank towards the pressurized water chamber and squeezing out the water inside the pressurized water chamber with the piston transmission rod. There will be a pressurization pause process during the reciprocating motion of the piston transmission rod, and this process is used to inject water into the pressurized water chamber, resulting in possible fluctuations in pressure and an unfixed pressure value.

[0006] To achieve the above object, this application adopts the following technical solutions:

Second air inlet ports are opened in the partition walls between the buffer chamber and the right driving chamber, and between the buffer chamber and the left driving chamber and inside the driving pipe.

[0013] By adopting the above technical solution, the first air inlet ports and the second air inlet ports are responsible for providing flow paths for high-pressure gas, prompting the high-pressure gas to expand the right driving chamber or the left driving chamber.

When the right water intake chamber takes water, the right water intake chamber cannot pressurize the water. At this time, the left water intake chamber begins to drain water to the water collecting tank to pressurize the water, thereby alleviating the pressure change during the alternating water intake process of the water intake chamber, ensuring the stability of the pressure output from the water collecting tank, and improving the transportation efficiency at the same time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0025] Refer to Figures 1-3, A constant high-pressure fire water supply system applicable to high-rise buildings, including a constant pressure air tank 1. The constant pressure air tank 1 is installed with a driving mechanism 2 through a pipeline. Both sides of the driving mechanism 2 are connected to a water storage tank 3 through two pipelines. A one-way valve flowing towards the driving mechanism 2 is installed on the pipeline between the driving mechanism 2 and the water storage tank 3. Both sides of the driving mechanism 2 are connected to a water collecting tank 5 through two pipelines. A one-way valve flowing towards the water collecting tank 5 is installed on the pipeline between the driving mechanism 2 and the water collecting tank 5. Two air outlet pipes 6 extend from below the driving mechanism 2.

[0026] Refer to Figures 1-3 , A buffer chamber 202 is arranged inside the driving mechanism 2. A right driving chamber 203 and a left driving chamber 205 are arranged on both sides of the buffer chamber 202. A right water intake chamber 204 and a left water intake chamber 206 are respectively arranged on the sides of the right driving chamber 203 and the left driving chamber 205 away from the buffer chamber 202. The interiors of the right water intake chamber 204 and the left water intake chamber 206 are connected and communicated with the water collecting tank 5. The working principle of this device is that when the right water intake chamber 204 draws water from the water storage tank 3, the right water intake chamber 204 cannot output water pressure to the water collecting tank 5. However, during the process of the right water intake chamber 204 drawing water from the water storage tank 3, the left water intake chamber 206 starts to drain water to the water collecting tank 5 and output water pressure. The right water intake chamber 204 and the left water intake chamber 206 drain water outward alternately, thus ensuring the stability of the water pressure in the water collecting tank 5.

[0027] Refer to Figures 1-3 , A water pump 4 is installed on the pipeline where one side of the water storage tank 3 is installed and connected to the driving mechanism 2. To ensure the normal cooperation between the right water intake chamber 204 and the left water intake chamber 206, it is necessary to initialize the internal working environment of the driving mechanism 2 at the beginning. The initialization is to add water to the right water intake chamber 204, so that the space of the right water intake chamber 204 expands, and at the same time squeeze the left water intake chamber 206, so that the space of the left water intake chamber 206 is compressed to the minimum. At this time, the space of the right driving chamber 203 is the smallest and the space of the left driving chamber 205 is the largest. Then the water pump 4 can stop working, that is, the initialization of the internal working environment of the driving mechanism 2 is completed.

[0028] Refer to Figures 1-3, the driving mechanism 2 includes a cylinder 201. A buffer chamber 202 is arranged in the middle of the cylinder 201. The buffer chamber 202 is connected and communicated with the constant pressure gas tank 1. At the upper end inside the buffer chamber 202, a driving pipe 207 is provided. Two first air inlets 208 are opened on both sides of the driving pipe 207. A sealing block 209 is slidably sleeved inside the driving pipe 207. Second air inlets 210 are opened in the partition walls between the buffer chamber 202 and the right driving chamber 203, between the buffer chamber 202 and the left driving chamber 205, and inside the driving pipe 207. In the initial state, the constant pressure gas tank 1 injects high-pressure air into the buffer chamber 202. The high-pressure air enters the first air inlet 208 on the right side of the driving pipe 207 through the buffer chamber 202, then enters the second air inlet 210 through the first air inlet 208, enters the right driving chamber 203, and expands the space of the right driving chamber 203, thereby squeezing out the water inside the right water intake chamber 204, thus completing the output pressurization of the water inside the right water intake chamber 204.

[0029] Refer to Figures 1-3 , a transmission shaft 212 penetrates through the middle of the partition walls between the buffer chamber 202 and the right driving chamber 203 and the left driving chamber 205. Sealing plates 211 are fixedly connected to both sides of the transmission shaft 212. During the expansion of the right driving chamber 203, the sealing plate 211 on the side of the right driving chamber 203 drives the sealing plate 211 on the side of the left driving chamber 205 to move to the right through the transmission shaft 212, causing the left driving chamber 205 to be squeezed by the sealing plate 211, and the space of the left water intake chamber 206 on the left side of the left driving chamber 205 expands. While expanding, it starts to draw water from the reservoir 3 inside, that is, the operation of drawing water from the reservoir 3 by the left water intake chamber 206 is completed.

[0030] Refer to Figures 1-3, a right electric air valve 213 is installed on the partition wall between the buffer chamber 202 and the right drive chamber 203, and a left electric air valve 214 is installed on the partition wall between the buffer chamber 202 and the left drive chamber 205. Pull ropes 215 are movably connected to both sides of the two sealing plates 211 and the sealing block 209. An air outlet pipe 6 is installed at the lower ends of the right electric air valve 213 and the left electric air valve 214. When the right drive chamber 203 expands to the maximum, the right water intake chamber 204 on the right side of the right drive chamber 203 is squeezed into the smallest space. The sealing plate 211 between the right drive chamber 203 and the right water intake chamber 204 continues to move to the right under the action of air pressure, pulling the pull rope 215 located on the sealing plate 211. The pull rope 215 drives the sealing block 209 to move to the right, blocking the first air inlet 208 on the right side of the drive pipe 207 and opening the first air inlet 208 on the left side of the drive pipe 207. Gas then enters the second air inlet 210 on the left side of the buffer chamber 202 from the first air inlet 208 on the left side of the drive pipe 207, and then enters the left drive chamber 205, expanding the left drive chamber 205 and compressing the left water intake chamber 206 to drain water outward. The movement of the left sealing plate 211 drives the movement of the right sealing plate 211, causing the right drive chamber 203 to be compressed and the right water intake chamber 204 to start drawing water. At this time, the right electric air valve 213 inside the buffer chamber 202 is opened and the left electric air valve 214 is closed, achieving a state where the left drive chamber 205 is sealed and the right drive chamber 203 leaks air, that is, completing one cycle. Through multiple cycles, the intermittent water supply state of the left water intake chamber 206 and the right water intake chamber 204 is realized to ensure the stability of the water pressure inside the water collection tank.

[0031] Working principle: The working principle of this device is that when the right water intake chamber 204 draws water from the reservoir 3, the right water intake chamber 204 cannot output water pressure to the water collection tank 5. However, during the process of the right water intake chamber 204 drawing water from the reservoir 3, the left water intake chamber 206 starts to drain water to the water collection tank 5 and output water pressure. The right water intake chamber 204 and the left water intake chamber 206 drain water outward alternately, thus ensuring the stability of the water pressure inside the water collection tank 5. To ensure the normal cooperation between the right water intake chamber 204 and the left water intake chamber 206, it is necessary to initialize the internal working environment of the drive mechanism 2 at the beginning. Initialization is achieved by adding water to the right water intake chamber 204, causing the space of the right water intake chamber 204 to expand, and at the same time squeezing the left water intake chamber 206, causing the space of the left water intake chamber 206 to be compressed to the smallest. At this time, the space of the right drive chamber 203 is the smallest and the space of the left drive chamber 205 is the largest. Then the water pump 4 can stop working, that is, completing the initialization of the internal working environment of the drive mechanism 2;

[0032] In the initial state, the constant-pressure gas tank 1 injects high-pressure air into the interior of the buffer chamber 202. The high-pressure air enters the first air inlet 208 on the right side of the drive tube 207 through the buffer chamber 202, then enters the second air inlet 210 through the first air inlet 208, and enters the right drive chamber 203, expanding the space of the right drive chamber 203, thereby squeezing out the water inside the right water intake chamber 204, thus completing the output pressurization of the water inside the right water intake chamber 204. During the expansion of the right drive chamber 203, the sealing plate 211 on the side of the right drive chamber 203 drives the sealing plate 211 on the side of the left drive chamber 205 to move to the right through the transmission shaft 212, causing the left drive chamber 205 to be squeezed by the sealing plate 211, and the space of the left water intake chamber 206 on the left side of the left drive chamber 205 expands. While expanding, it starts to draw water from the interior of the water storage tank 3, that is, the operation of drawing water from the left water intake chamber 206 to the water storage tank 3 is completed;

[0033] When the right drive chamber 203 expands to the maximum, the right water intake chamber 204 on the right side of the right drive chamber 203 is squeezed into the smallest space. The sealing plate 211 between the right drive chamber 203 and the right water intake chamber 204 continues to move to the right under the action of air pressure, pulling the pull rope 215 located on the sealing plate 211. The pull rope 215 drives the sealing block 209 to move to the right, blocking the first air inlet 208 on the right side of the drive tube 207, opening the first air inlet 208 on the left side of the drive tube 207. The gas then enters the second air inlet 210 on the left side of the buffer chamber 202 from the first air inlet 208 on the left side of the drive tube 207, and then enters the left drive chamber 205, expanding the left drive chamber 205, compressing the left water intake chamber 206, and discharging water outward. The movement of the left sealing plate 211 drives the movement of the right sealing plate 211, causing the right drive chamber 203 to be compressed, and the right water intake chamber 204 starts to draw water. At this time, the right electric air valve 213 inside the buffer chamber 202 is opened, and the left electric air valve 214 is closed, realizing the state where the left drive chamber 205 is sealed and the right drive chamber 203 leaks air. That is, one cycle is completed. Through multiple cycles, the intermittent water supply states of the left water intake chamber 206 and the right water intake chamber 204 are realized to ensure the stability of the water pressure inside the water collecting tank.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and the inventive concept of the present application, makes equivalent replacements or changes, and should be covered by the protection scope of the present application.
