[0022] Please see Figures 1 to 6 The present invention provides a fire-fighting water tank for high-rise buildings. A fire-fighting water tank for high-rise buildings includes a tank body 10, a support frame 20, a rainwater storage tank 30, a baffle plate 40, and a transition tank 50. The tank body 10 is installed on the top of the high-rise building. The support frame 20 is located outside the tank body 10, and its upper end is higher than the top of the tank body 10. The rainwater storage tank 30 is fixedly installed on the support frame 20 and located above the tank body 10. A drain outlet 31 is provided at the lower part of the side wall of the rainwater storage tank 30, and a water inlet 32 ​​is provided in the middle of the side wall. The baffle plate 40 is fixedly installed on the rainwater storage tank. Above the tank 30; the upper end of the guide plate 40 is provided with an inclined surface 41 for guiding rainwater to flow downward; the transition tank 50 is located on one side of the rainwater storage tank 30, and the upper end is provided with an inlet 51 corresponding to the lower end of the guide plate 40; the transition tank 50 is provided with a first filter screen 52, and the first filter screen 52 is used to divide the interior of the transition tank 50 into a miscellaneous storage chamber 53 and a water storage chamber 54 arranged vertically; the side wall of the transition tank 50 is provided with an outlet 55 connected to the inlet 32, and the outlet 55 is connected to the water storage chamber 54.

[0023] Compared with the prior art, the fire water tank for high-rise buildings provided by this utility model includes a water tank body 10 installed on the top of the high-rise building, a support frame 20 located outside the water tank body 10 with its upper end surface higher than the top of the water tank body 10, a rainwater storage tank 30 fixed on the support frame 20 and located above the water tank body 10, a guide plate 40 installed above the rainwater storage tank 30, and a transition box 50 located on one side of the rainwater storage tank 30. The rainwater storage tank 30 has a drain outlet 31 at the bottom of its side wall for supplying stored rainwater to the tank body 10. The inlet 32 ​​in the middle of the side wall is connected to the outlet 55 of the transition tank 50. The inclined surface 41 at the top of the guide plate 40 can efficiently guide the rainwater to the inlet 51 at the top of the transition tank 50. The first filter screen 52 inside the transition tank 50 divides its interior into a mixed impurity storage chamber 53 and a water storage chamber 54, which can effectively intercept impurities in the rainwater, ensuring that the water entering the rainwater storage tank 30 is clean and preventing blockage of the fire water supply equipment. In use, first, complete the precise installation of each component to ensure that the water tank body 10 is firmly fixed to the roof, the support frame 20 provides reliable support, the positions of the rainwater storage tank 30, the guide plate 40 and the transition tank 50 are accurately aligned, and the connection between the outlet 55 and the inlet 32 ​​is well sealed. When it rains, the inclined surface 41 of the guide plate 40 guides the rainwater to the inlet 51 of the transition tank 50. After entering the transition tank 50, the rainwater is filtered by the first filter screen 52, and impurities are trapped in the impurity storage chamber 53. The purified rainwater enters the water storage chamber 54 and then flows into the rainwater storage tank 30 for storage through the connecting structure between the outlet 55 and the inlet 32. When the water level in the fire water tank drops and needs to be replenished, the rainwater storage tank 30 uses the drain outlet 31 to gravity transport the stored purified rainwater to the water tank body 10 to replenish the fire water, without the need to frequently start the pressurization equipment to draw tap water. By collecting and utilizing rainwater resources to supplement fire-fighting water, the frequency of pressurization equipment drawing tap water is significantly reduced, effectively reducing power consumption and significantly lowering the overall operating cost of the building.

[0024] The recycling and reuse of rainwater resources aligns with energy conservation and environmental protection principles, contributing to the sustainable use of water resources and conforming to the trend of green building development. The filtration structure of the transition box 50 ensures the cleanliness of fire-fighting water, preventing impurities from clogging core equipment such as fire hydrants and automatic sprinkler systems, thus improving the reliability of the fire-fighting water supply system. The rainwater storage tank 30, located above the water tank body 10, can quickly respond to water replenishment needs, ensuring that the fire-fighting water tank always maintains the specified water level, further enhancing the stability of water supply in the early stages of a fire.

[0025] The lower end of the support frame 20 is provided with a pad 21, and a plurality of reinforcing plates 22 arranged circumferentially are provided between the pad 21 and the support frame 20.

[0026] Please see Figure 1 and Figure 4As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, the transition tank 50 is a long strip structure arranged along the length of the rainwater storage tank 30, and the inlet 51 is arranged along the length of the transition tank 50; there are multiple outlets 55, which are arranged at intervals along the length of the rainwater storage tank 30; there are multiple inlets 32, which correspond one-to-one with multiple outlets 55; the long strip transition tank 50 and the extended inlet 51 can greatly improve the rainwater collection area and efficiency, and quickly collect more rainwater; the corresponding arrangement of multiple sets of outlets 55 and inlets 32 can make the purified rainwater flow evenly into the rainwater storage tank 30, avoiding the problems of local water accumulation or excessive water flow impact. This method not only accelerates the rainwater replenishment rate and ensures that the fire water tank quickly returns to the prescribed water level, but also ensures a balanced water flow distribution within the rainwater storage tank. At the same time, multiple inlet and outlet structures can disperse water flow pressure, reduce the risk of blockage, and further improve the stability and reliability of the entire water supply system, making it better suited to the fire water needs of high-rise buildings.

[0027] Please see Figures 1 to 4 As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, the transition tank 50 is provided with an upwardly extending strip baffle 56 on the side corresponding to the rainwater storage tank 30; the strip baffle 56 can effectively prevent rainwater in the transition tank 50 from overflowing outward due to water flow impact or excessive water volume during rainfall, especially in extreme weather such as rainstorms, which can avoid water waste and reduce the impact of water splash on surrounding components.

[0028] Please see Figure 3 As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, a first cleaning port 57 and a first sealing door 58 for sealing the first cleaning port 57 are provided on the side of the transition box 50 away from the rainwater storage tank 30. The first sealing door 58 is movably connected to the transition box 50; the first cleaning port 57 corresponds to the first filter screen 52.

Without disassembling the transition box 50 or other related components, the first filter screen 52 can be directly cleaned by opening the first sealing door 58, which is convenient and efficient. This structure can promptly remove accumulated impurities on the first filter screen 52, avoiding clogging of the first filter screen from affecting the rainwater filtration efficiency and replenishment rate; and reducing the wear and tear on the first filter screen and the transition box 50 caused by long-term impurity adhesion.

[0029] Please see Figure 3As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, the first closed door 58 is provided with an observation port 59 for observing the interior of the transition tank 50, allowing for a direct view of the tank's interior without opening the first closed door 58. The observation port 59 enables visual monitoring of the internal state of the transition tank 50, accurately determining the degree of impurity buildup on the first filter screen 52, the water quality and flow in the water storage chamber 54, avoiding the operational redundancy caused by blindly opening the first closed door 58. This method allows for timely detection and cleaning of problems such as clogging of the first filter screen, ensuring rainwater filtration and replenishment efficiency, and reducing unnecessary door opening operations.

[0030] Please see Figure 1 , Figure 4 and Figure 5 As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, the guide plate 40 is provided with two symmetrically arranged inclined surfaces 41, and two transition tanks 50 are symmetrically arranged on both sides of the rainwater storage tank 30, with water inlets 32 on both side walls of the rainwater storage tank 30. This symmetrical structure maximizes the utilization of the rainfall area, the two inclined surfaces 41 can efficiently guide rainwater from both sides, and the two transition tanks 50 collect and filter rainwater simultaneously, greatly improving the efficiency of rainwater collection and replenishment, while making the overall stress more balanced. This method accelerates the recovery speed of the fire water tank water level and ensures the stability of water supply in the early stages of a fire.

[0031] Please see Figure 1 As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, a second filter screen 33 is provided inside the rainwater storage tank 30, and the second filter screen 33 is located below the outlet 55; the second filter screen 33 is installed below the outlet 55 inside the rainwater storage tank 30, forming a dual filtration system with the first filter screen 52. This structure can perform secondary purification of rainwater, accurately intercepting fine impurities that are not removed by the first filter screen 52, making up for the shortcomings of single-stage filtration, and further improving the quality of rainwater. The second filter screen 33 effectively prevents fine impurities from entering the fire water supply system and prevents clogging of fire hydrants.

[0032] Please see Figure 1 , Figure 4 and Figure 5As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, a second cleaning port 34 and a second sealing door 35 for sealing the second cleaning port 34 are provided at one end of the rainwater storage tank 30. The second sealing door 35 is movably connected to the rainwater storage tank 30. The second cleaning port 34 corresponds to the second filter screen 33, so that the cleaning of the second filter screen 33 is precise and targeted. There is no need to disassemble the rainwater storage tank 30 or related pipelines. Only the second sealing door 35 needs to be opened to directly carry out the impurity cleaning operation. The operation is convenient and does not affect the overall operation of the system. This method can remove the fine impurities accumulated on the second filter screen 33 in a timely manner, avoid the rainwater flow obstruction caused by filter screen blockage, and ensure the purification efficiency and replenishment rate of the dual filtration system.

[0033] Please see Figure 5 Figure 6 As a specific embodiment of the fire water tank for high-rise buildings provided by this utility model, both sides of the guide plate 40 are provided with upwardly extending baffles 42. The baffles 42 extend outward to increase the water collection area. The outward extension design of the baffles 42 specifically increases the rainwater collection area, while the upward extension structure can form a containment effect. The baffles 42 can maximize the capture of rainfall from different directions, effectively reducing the side overflow of rainwater from both sides of the guide plate 40. Combined with the original inclined surface 41 of the guide plate 40, the efficiency and utilization rate of rainwater collection are further improved. This structure allows more rainwater to be collected and replenished to the fire water tank, accelerating the water level recovery speed.

[0034] Please see Figure 6 As a specific embodiment of the fire-fighting water tank for high-rise buildings provided by this utility model, the rainwater storage tank 30 is provided with a clearance recess 36 corresponding to the manhole 11 of the water tank body 10. The clearance recess 36 on the rainwater storage tank 30, corresponding to the manhole 11 of the water tank body 10, achieves spatial clearance through the recessed structure, avoiding positional interference between the rainwater storage tank 30 and the manhole 11 of the water tank body 10. This structure does not require changing the original design layout of the water tank body 10 and the manhole 11, nor does it require adjusting the overall installation position of the rainwater storage tank 30. While ensuring that the functions of each component are not affected, it achieves a compact layout of both, making full use of the limited space at the top of the high-rise building. The clearance recess 36 allows personnel to smoothly enter the water tank body 10 through the manhole 11 for inspection, maintenance, and other operations, avoiding obstruction of operation and maintenance work due to spatial conflicts; no additional structural modifications are required, reducing design and construction costs.
