Description

Water storage tank

Technical Field

The utility model relates to a water storage device field especially relates to a be applied to storage water tank in high-rise building secondary water supply pump room.

Background

The stainless steel assembled water tank is a water storage device commonly adopted by a secondary water supply pump room of a high-rise building, and compared with a traditional concrete water tank, the stainless steel assembled water tank has the characteristics of convenience in construction and small water pollution. The water storage tank is assembled from a plurality of steel plates, and the dimension of the steel plates is usually 1000mm or 500mm, wherein the length is multiplied by the width. The bottom of the water storage tank is provided with a plurality of concrete foundations, the length of each foundation is B +300mm (B is the width of the water storage tank), the width of each foundation is 300mm, the height of each foundation is not less than 500mm, and the distance between the center lines of the two adjacent concrete foundations is 1000 mm. The water storage tank is usually manufactured and assembled on site by a professional manufacturer.

As shown in fig. 1 to 3, a conventional stainless steel water storage tank 1 is installed inside a water supply pump room 7, and is assembled by a plurality of stainless steel panels 11. The water storage tank 1 is provided with a top plate 12, a bottom plate 13 and a plurality of side plates 14 connecting the top plate 12 and the bottom plate 13, wherein the top plate 12 is provided with a manhole 15, and the bottom plate 13 is supported on a plurality of elongated concrete foundations 4 through a steel section base 5. The tank 1 is fed by a municipal water inlet pipe 6, the municipal water inlet pipe 6 has a horizontal section 61 and a vertical section 62, the horizontal section 61 is provided with a ball float valve 63, the vertical section 62 passes downwards through the top plate 12 and enters the interior of the tank 1, and the water outlet of the vertical section 62 is higher than the highest water level Z1 in the tank.

In order to meet the requirements of national and industrial relevant specifications and construction assembly, maintenance and repair space, the water storage tank is often assembled into a cuboid in a square manner, so that the water storage tank has the following defects:

1) the occupied space is large, the volume utilization rate is not high, and the waste of the space of the pump room and the steel plate material is caused. In practical engineering, a water storage tank is positioned in a basement of a high-rise building, an equipment floor of an intermediate floor or a roof and the like, the volume and the effective water level of the water storage tank are limited by the space of a pump house, a municipal water inlet pipe, the construction and maintenance clearance and the installation elevation and the size of a water suction pipe of a pressurizing equipment, and relevant regulations are provided for the water supply and drainage design standards of the building (GB 50025) and the technical regulations of secondary water supply engineering (CJJ-2010).

In order to meet the national and industrial standards, the water storage tank has to meet relevant size limitations in practical engineering, and the limitations tend to compress effective utilization volume, so that the water storage tank occupies large space and has small available effective volume, and steel plate materials are wasted. For a rectangular stainless steel water storage tank in a square shape, as shown in fig. 2, taking a commonly used 3m high water storage tank as an example, under the condition of no structural beam influence, the net height H0 of a pump room is not less than 4.3m (the height of the water storage tank is 3m + the bottom overhaul clearance H5 is 0.5m + the top manhole clearance H3 is 0.8m), but the available effective water depth H1 of the water storage tank is only 2.2m (the height of the water storage tank is 3 m-0.3 m above the highest water level Z1, the clearance H2-0.5 m below the lowest water level Z2, the unavailable dead water zone H4 is 0.5m), and the effective utilization rate is 73.33% (the effective volume/total volume is 100% — 2.2/3 is 100%).

2) The water level in the water vapor wetting zone H7 above the highest water level Z1 and the water level change dry-wet alternation zone H8 below the highest water level Z1 within 0.2m range are relatively large, which causes the corrosion of steel plates, pollutes the water quality and reduces the service life of the water storage tank. As shown in fig. 3, the dimension specification of the water storage tank is length, width, height, L, B, H, the area of the stainless steel plate of the water storage tank exposed to the water vapor wetting zone H7 is (L, B +2, 0.3, L +2, 0.3, B), the area of the stainless steel plate in the water level fluctuation dry-wet alternation zone H8 is (2, 0.2, L +2, 0.2, B), and the area of the stainless steel plate of the water storage tank susceptible to rusting (the sum of the areas of the water vapor wetting zone and the water level fluctuation dry-wet alternation zone) is (L, B + L + B). The net height H0 of the pump room is equal to the height of a water sealing area H6 + the height of a bottom overhaul clearance H5 + the height of a water vapor wetting area H7 + the height of a top clearance H3 + the height of a water level change dry-wet alternating area H8.

Therefore, there is a need for a new water storage tank.
