[0029] like Figure 1As shown, in one embodiment of the present invention, the water replenishment system of the fire-fighting transfer water tank 407 includes a rainwater collection device 1, a rainwater conduction pipe 2, a filter device 3, and a clean water storage device 4. Among them, one end of the rainwater collection device 1 is arranged on the top of the super high-rise building, and the other end is connected to one end of the rainwater conduction pipe 2, and is used to collect rainwater on the roof of the super high-rise building; the other end of the rainwater conduction pipe 2 is connected to the clean water storage device 4, the filter device 3 is arranged on the rainwater conduction pipe 2 between the rainwater collection device 1 and the clean water storage device 4, and is used to filter the rainwater flowing through the rainwater conduction pipe 2, and the clean water storage device 4 is used to store the rainwater filtered by the filter device 3.
[0030] The rainwater collecting device 1 is arranged at a first position 5 of the super high-rise building, and the clean water storage device 4 and the filtering device 3 are arranged at a second position 6 of the super high-rise building. When it rains, rainwater falling on the top of the super high-rise building flows into the rainwater collecting device 1, and stands still in the rainwater collecting device 1 for a period of time, so that impurities such as mud, stones, etc. are settled at the bottom of the rainwater collecting device 1. The rainwater is introduced into the clean water storage device 4 through the rainwater conducting pipe 2. During this process, the rainwater flows through the filtering device 3. Since the height of the first position 5 is greater than the height of the second position 6, the height difference between the two is used to pressurize the rainwater flowing through the filtering device 3, thereby improving the filtering efficiency of the filtering device 3 for rainwater, and treating the rainwater to the standard of fire-fighting water. Finally, the rainwater is stored in the clean water storage device 4 for fire-fighting use.
[0031] Specifically, Figure 1 As shown, the first position 5 is the highest refuge floor of the super high-rise building, and the second position 6 is the middle refuge floor of the super high-rise building. Rainwater flows from the highest refuge floor to the middle refuge floor, generating a pressure difference in the filter device 3, thereby accelerating the filtration speed and improving the filtration efficiency. The filter device 3 is mainly composed of a filter screen and a PH regulator. The filter screen blocks fine impurities in the rainwater, and the PH regulator ensures that the rainwater entering the clean water storage device 4 is neutral.
[0032] In one embodiment of the utility model, the rainwater collection device 1 includes a rainwater gutter 101 disposed on the top of a super high-rise building, a rainwater tank 103 disposed at the first position 5, and a rainwater collecting pipe 102; the bottom end of the rainwater gutter 101 is connected to one end of the rainwater collecting pipe 102, the other end of the rainwater collecting pipe 102 is connected to the rainwater tank 103, and the rainwater conducting pipe 2 is connected to the rainwater tank 103. The rainwater gutter 101 is in the shape of a funnel, the top of which is flush with the roof of the top of the super high-rise building, and the throat is connected to one end of the rainwater collecting pipe 102. Rainwater is collected by the rainwater gutter 101 and conducted to the rainwater tank 103 through the rainwater collecting pipe 102 for storage. The rainwater is left in the rainwater tank 103 for a period of time, and impurities such as mud, sand, and gravel are precipitated at the bottom of the rainwater tank 103.
[0033] Further, such as Figure 1As shown, in one embodiment of the present invention, a third valve 107 is installed between the rainwater tank 103 and the rainwater conduction pipe 2. When the amount of fire water stored in the clean water storage device 4 is sufficient, the third valve 107 is closed, and the rainwater is fully settled in the rainwater tank 103. A water level meter 109 is installed on the outside of the rainwater tank 103, and the staff can judge the water storage amount in the rainwater tank 103 by observing the water level meter 109. A vent pipe 105 is installed at the bottom of the rainwater tank 103, and a fourth valve 108 is installed between the vent pipe 105 and the rainwater tank 103. When the fire water stored in the water storage device is consumed, the fourth valve 108 is first opened to discharge the precipitated impurities, and then the fourth valve 108 is closed and the third valve 107 is opened. At this time, the rainwater impurities flowing through the filter device 3 are less, which can increase the service life of the filter device 3; an overrunning pipe 106 is installed between the vent pipe 105 and the rainwater collecting pipe 102. When the rainwater tank 103 is full, the rainwater in the rainwater collecting pipe 102 is discharged to the ground through the overrunning pipe 106. In this embodiment, the third valve 107 and the third valve 107 are both ordinary valves, such as ball valves and butterfly valves, and the technical content of this implementation can be realized by manual or computer control.
[0034] Among them, Figure 1 As shown, a vent pipe 104 is provided on the top of the rainwater tank 103, and the vent pipe 104 is C-shaped. The rainwater collecting pipe 102 is connected to the middle of the vent pipe 104, and one end of the vent pipe 104 extends into the rainwater tank 103, so that the gas in the rainwater tank 103 can circulate with the outside. The rainwater collected in the rainwater tank 103 may carry some dust, sand and other impurities. The vent pipe 104 can be provided to ventilate the water tank and prevent the rainwater from deteriorating. The C-shape is a common practice for the vent pipe 104.
[0035] Further, such as Figure 1 As shown, in one embodiment of the utility model, a sand settling hopper 110 is provided at the bottom of the rainwater tank 103. The structure of the sand settling hopper 110 can be truncated cone or cylindrical. The bottom of the rainwater tank 103 is provided with a slope and slopes toward the sand settling hopper 110. The sediment in the rainwater tank 103 gradually gathers in the sand settling hopper 110 under the action of the slope. The sand settling hopper 110 protrudes from the bottom of the rainwater tank 103. At this time, even if the impurities in the rainwater tank 103 are not discharged in advance, when the water volume of the clean water storage device 4 is replenished, the impurities will not be brought into the filter device 3, making the operation of the fire transfer water tank replenishment system more convenient. The sand settling hopper 110 is connected to the vent pipe 105. After opening the fourth valve 108, the rainwater and impurities are discharged to the ground.
[0036] Among them, Figure 1As shown, in one embodiment of the present invention, the clean water storage device 4 includes a clean water tank 401, a transfer water tank 407, a clean water replenishment pipe 402, a tap water replenishment pipe 405, and a regulating unit; the clean water tank 401 is connected to the other end of the rainwater conduction pipe 2, the clean water tank 401 is connected to one end of the transfer water tank 407 through the clean water replenishment pipe 402, the tap water replenishment pipe 405 is connected to the other end of the transfer water tank 407, and the transfer water tank 407 is provided with a regulating unit for regulating the amount of tap water and filtered rainwater entering the transfer water tank 407.
[0037] The tap water replenishment pipe 405 is connected to the user's household tap water system. The water purification tank 401 is used to store rainwater treated by the filter device 3. It is a pressure-bearing container used to buffer the difference between the filtered rainwater volume and the fire water replenishment volume. Especially in fire fighting, the fire water volume demand is large. At this time, the water purification tank 401 plays the role of a dual water source for fire fighting. The transfer water tank 407 is directly connected to the fire fighting system and is the direct water supply end of the fire fighting system. Fire fighting requires that the transfer water tank 407 needs to meet the specified water storage volume for a long time. When the precipitation at the user's location is sufficient, the water storage in the water purification tank 401 is sufficient, and the regulating unit controls the water purification tank 401 to replenish the transfer water tank 407 through the water purification replenishment pipe 402 to maintain the specified water storage volume of the transfer water tank 407. When the rainfall at the user's location is insufficient, the water stored in the water purification tank 401 cannot maintain the specified water storage volume of the transfer water tank 407, and the transfer water tank 407 is replenished through the user's household tap water system. This will reduce the use of household tap water and save water resources.
[0038] Further, such as Figure 1 As shown, the regulating unit includes a water level monitor 404, a first valve 403, and a second valve 406; the first valve 403 is installed at the water outlet end of the clean water supply pipe 402, and the second valve 406 is installed at the water outlet end of the tap water supply pipe 405. A water level monitor 404 is arranged in the transfer water tank 407, and the water level monitor 404 controls the opening and closing of the first valve 403 and the second valve 406 according to a first water level line and a second water level line, and the first water level line is higher than the second water level line.
[0039] like Figure 1As shown, in one embodiment of the present invention, the first valve 403 is a float valve, the second valve 406 is a solenoid valve, the first water level and the second water level are set in the water level monitor 404, and the first water level is located above the second water level. The water level monitor 404 is set in the transfer water tank 407, and the float in the first valve 403 is set to be flush with the first water level. When the water level in the transfer water tank 407 is higher than or flush with the first water level, the float in the first valve 403 is lifted by the water, thereby closing the first valve 403. When the water level in the transfer water tank 407 is between the first water level and the second water level, the float automatically opens the first valve 403 due to gravity, and rainwater flows from the clean water tank 401 into the transfer water tank 407. When the rainfall at the user's location is insufficient, the water level in the transfer water tank 407 continues to drop below the second water level line, and the second valve 406 is electrically connected to the water level monitor 404. The water level monitor 404 controls the second valve 406 to open, and household tap water replenishes the transfer water tank 407 through the tap water replenishment pipe 405. The second valve 406 is not closed until the water level in the transfer water tank 407 reaches the set first water level line.
[0040] In addition, if Figure 1 As shown, in one embodiment of the present invention, a closed manhole is provided on the top of the rainwater tank 103. The closed manhole is provided to facilitate the inspection of the rainwater tank 103 and to prevent rainwater from overflowing into the room.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and description of the utility model.
