Description

Technical Field

[0001] This utility model relates to a water storage device, and more particularly to a water storage device for a prefabricated SLRC smart fire pump station. Background Technology

[0002] Traditional fire pump stations use concrete-lined water tanks, and the fire protection system is assembled like building blocks, with individual components piecemeal. Furthermore, the technical skill levels of the construction and installation teams vary considerably, leading to significant problems in practical implementation.

[0003] First, it occupies a large area; this is mainly reflected in the fire pump room. Traditional fire pump rooms are assembled on-site using individual equipment in a modular fashion, resulting in very poor product integration. Considering the limitations of later inspections, maintenance, and traditional civil engineering construction techniques, fire pump rooms often occupy a relatively large area.

[0004] Secondly, the construction period is long. Traditional fire pump stations, whether for fire water tanks or pump rooms, use concrete masonry, which requires multiple processes such as excavation, foundation compaction, steel reinforcement binding, initial concrete pouring, concrete setting, secondary concrete pouring, and further setting. This results in a very long construction period. Furthermore, if affected by weather conditions (rain), temperature, or other environmental factors, the construction period will be further extended, and project progress cannot be guaranteed.

[0005] Third, the cost is high. Traditional concrete-built water tanks are bulky and cumbersome due to process requirements and thickness, resulting in higher costs. Additionally, the large footprint mentioned earlier increases construction costs. Furthermore, the long construction period and rising labor costs further contribute to the high cost of traditional fire pump stations.

[0006] Fourth, it is prone to microbial growth; the concrete inner wall of the fire water tank, due to long-term immersion in water and the poor water flow, is susceptible to microbial growth. Once microorganisms proliferate, they can easily enter the fire protection system with the fire water, potentially clogging pumps, pipes, valves, and instruments, posing a significant hidden danger to the fire water system. Even with increased cleaning frequency, maintenance costs will increase considerably.

[0007] Fifth, the risk of leakage and seepage; traditional concrete water tanks, even with waterproofing, pose a significant risk of leakage and seepage if not regularly maintained and waterproofed. Regular waterproofing is costly. Without waterproofing, leakage and seepage are extremely easy to occur. Once a fire water tank leaks, the impact on the entire fire protection system is devastating.

[0008] Sixth, the products have low levels of intelligence and pose significant safety hazards. In traditional fire pump stations, the equipment installed in the pump room is often assembled on-site like building blocks, without any overall intelligent or IoT-based setup. Regular inspections rely on manual labor and the inspectors' sense of responsibility, which poses a significant risk to ensuring the fire equipment is readily available and safe to use.

[0009] Existing prefabricated SLRC water tanks often suffer from sealing problems, and the sealing of the water tank is of paramount importance. In addition, the installation and maintenance of the side walls of prefabricated SLRC water tanks are relatively complex. Utility Model Content

[0010] To address the aforementioned issues, the main objective of this utility model is to provide a prefabricated fire pump station water tank made of prefabricated SLRC material. This allows for the on-site assembly of the fire pump station construction process, while also providing good sealing performance and convenient installation and maintenance.

[0011] To solve the above-mentioned technical problems, the present invention provides a prefabricated fire pump station water tank comprising a valve base plate 1 located on the bottom surface and four side walls 5. Each side wall 5 comprises several steel frames 21 arranged vertically at equal intervals and several plates 11. Each steel frame 21 has slots 211 on its two sides for accommodating the side edges 111 of the plates 11. Each plate 11 is disposed between two steel frames 21, and its two side edges 111 are respectively embedded in the corresponding slots 211 of the two steel frames 21 for fixation. A sealing element is provided between the side edges 111 and the slots 211 to form a sealed connection.

[0012] Furthermore, the steel frame 21 is an I-shaped frame composed of a T-shaped profile body 200 and an inner sealing pressure plate 25.

[0013] Furthermore, the T-shaped profile body 200 and the inner sealing pressure plate 25 can be fixed by screws 26 so as to install the inner sealing gasket (23) between the steel frame (21) and the plate (11). The end plate (201) of the T-shaped profile body (200) is fixed to the T-shaped profile body (200) by the first fixing screw (22).

[0014] Furthermore, the pool can also be fitted with a cover 500 to ensure safety and prevent impurities or debris from falling in.

[0015] Furthermore, the valve base plate 1 is made of concrete. The bottom end 291 of the steel frame 21 is fixed to the pre-embedded foundation plate 42, and a certain length of its lower end is pre-embedded in the concrete of the valve base plate 1 for fixation. The surface of the pre-embedded foundation plate 42 is nearly parallel to the bottom surface. In addition, the pre-embedded foundation plate 42 is fixed with several pre-embedded anchor screws 43 in a direction perpendicular to its surface. In this way, after the concrete of the valve base plate 1 has solidified, the pre-embedded anchor screws 43, the steel frame 21, the pre-embedded foundation plate 42 and the valve base plate 1 are fixed together. The pre-embedded anchor screws 43 are further embedded in the concrete of the valve base plate 1, which plays a further reinforcement role.

[0016] Furthermore, a layer of sealant 140 is applied to the bottom of the valve base plate 1 to form an anti-leakage seal and prevent leakage.

[0017] Furthermore, the fixing plate 48 of the bottom end 291 of the steel frame 21 is fixed to the pre-embedded foundation plate 42 by fastening screws 41, and the bottom end 291 of the steel frame 21 and the fixing plate 48 can be fixed by welding or other methods.

[0018] Furthermore, the plate 11 is made of SLRC material, and it is mainly composed of horizontal and vertical steel bars 12, concrete 13 and a hollow metal shell 14, the interior of which is made of poured concrete.

[0019] Furthermore, the metal casing 14 is made of stainless steel.

[0020] Furthermore, the metal casing 14 adopts the shape of the plate 11 to be manufactured. An opening 140 for pouring concrete is provided on the outer wall surface 149. In addition to the opening 140, a sealing surface 141 of a certain length is provided on the outer wall surface 149 near the two sides 111. This length is equivalent to the horizontal depth of the groove 211, but is usually greater than this depth so that the outer sealing gasket 23 provided between the outer surface of the sealing surface 141 of the plate 11 and the inner surface of the groove 211 can form a stable seal.

[0021] This utility model provides a prefabricated fire pump station water tank with an SLRC material panel 11 featuring a novel double-sealing structure. It mainly consists of a steel frame 21, fastening screws 28, an outer sealing gasket 23, an inner sealing gasket 24, and an inner sealing pressure plate 25. The steel frame 21, SLRC material panel 11, inner sealing gasket 24, and inner sealing pressure plate 25 form the first seal. The steel frame 21, SLRC material panel 11, and outer sealing gasket 23 form the second seal. Unlike traditional fire pump stations where leakage requires extensive reconstruction and re-waterproofing of the entire water tank, the prefabricated SLRC intelligent fire pump station provided by this invention, even in special circumstances where leakage occurs, only requires identifying the leak point, loosening the fastening screws 28, opening the inner sealing pressure plate 25, and replacing the inner sealing gasket 24. This not only ensures sealing effectiveness and extends service life but also facilitates replacement, features not found in water tanks of other fire pump station structures. Moreover, the pool was assembled on-site from SLRC (Solid Lamination Reinforced Concrete) panels, secured with bolts and sealed with gaskets. This not only improves construction precision but also significantly shortens the construction period and reduces construction costs. Attached Figure Description

[0027] The preferred embodiments of this utility model are given below with reference to the accompanying drawings to illustrate the technical solution of this utility model in detail.

[0028] Figure 1 and Figure 3This is a schematic diagram of the installation arrangement of the water tank according to the present invention. The water tank of the present invention consists of a valve base plate 1 located on the bottom surface and four side walls 5. Each side wall 5 is made of several steel frames 21 arranged vertically at equal intervals and several plates 11. Each steel frame 21 has a groove 211 on two sides to accommodate the side edges 111 of the plate 11. Each plate 11 is placed between two steel frames 21, and its two side edges 111 are respectively embedded into the opposite grooves 211 of the two steel frames 21 for fixation. A sealing element is provided between the side edges 111 and the grooves 211 to form a sealed connection. In this embodiment, the steel frame 21 is integrally formed into an I-shaped profile frame by a T-shaped profile body 200 and an inner sealing pressure plate 25. The T-shaped profile body 200 and the inner sealing pressure plate 25 can be fixed by screws 26. This structure facilitates the installation of the seal between the steel frame 21 and the plate 11 (described below). The pool can also be equipped with a cover 500 to ensure safety and prevent impurities or debris from falling in. The cover 500 can be made of metal materials such as stainless steel and aluminum alloy or non-metal materials such as plastic. The end plate (201) of the T-shaped profile body (200) is fixed to the T-shaped profile body (200) by the first fixing screw (22).

[0029] See Figure 4 The valve base plate 1 is made of concrete. The bottom end 291 of the steel frame 21 is fixed to the pre-embedded foundation plate 42, and a certain length below it is embedded in the concrete of the valve base plate 1 for fixation. The surface of the pre-embedded foundation plate 42 is nearly parallel to the bottom surface. Furthermore, the pre-embedded foundation plate 42 is fixed with several pre-embedded anchor screws 43 in a direction perpendicular to its surface. Thus, after the concrete of the valve base plate 1 solidifies, the pre-embedded anchor screws 43, the steel frame 21, the pre-embedded foundation plate 42, and the valve base plate 1 are fixed together. The pre-embedded anchor screws 43 are deeply embedded in the concrete of the valve base plate 1, providing further reinforcement.

[0030] In addition, a layer of sealant 340 is applied to the bottom of the valve base plate 1 to form an anti-leakage seal and prevent leakage.

[0031] See also Figure 4 In this embodiment, the fixing plate 48 at the bottom 291 of the steel frame 21 is fixed to the embedded foundation plate 42 by fixing screws 41. The bottom 291 of the steel frame 21 and the fixing plate 48 can be fixed by welding or other methods.

[0032] See Figure 1 , Figure 2A and 2BThe slab 11 is made of SLRC material. Its main body consists of longitudinal and transverse reinforcing bars 12, concrete 13, and a hollow metal shell 14, which is formed by pouring concrete. In this embodiment, the metal shell 14 is made of stainless steel. Therefore, the SLRC slab 11 possesses the excellent load-bearing capacity, seismic resistance, and fire resistance of reinforced concrete, while also having the corrosion resistance and impermeability of stainless steel. The inner wall 142 of the SLRC slab 11, which is in contact with water, is entirely made of stainless steel, making it less prone to microbial growth compared to traditional concrete. The metal shell 14 follows the shape of the slab 11 to be manufactured, and has an opening 140 for pouring concrete on its outer wall 149 (right side in the figure). In addition to the opening 140, the outer wall 149 also has a sealing surface 141 of a certain length near the two sides 111. This length is comparable to the horizontal depth of the slot 211, but is typically greater than this depth so that the outer sealing gasket 23 disposed between the sealing surface 141 (outer surface) of the plate 11 and the inner surface of the slot 211 can form a stable seal (see...). Figure 3 ).

[0033] See 2B and Figure 3 The following is a process for installing or preparing a prefabricated SLRC smart fire pump station water tank:

[0034] First, at the location where the water tank (slab 11) needs to be installed, pour concrete to form the valve base plate 1 of the required size;

[0035] Then, an installation groove 100 is opened on the surface of the valve base plate 1 at the corresponding position where the side wall 5 needs to be installed, and a pre-embedded base plate 42 with several pre-embedded anchor screws 43 is placed at the bottom of the groove.

[0036] The fixing plate 48 of the steel frame 21 is further fixed to the pre-embedded foundation plate 42 by fixing screws 41;

[0037] Then fill the mounting slot 100 with concrete and let it solidify.

[0038] After the concrete in the installation groove 100 has solidified, the plate 11 is inserted into the T-shaped profile body 200 between the two steel frames 21. An outer sealing gasket 23 is set between the outer wall surface 149 and the two inner surfaces of the floor of the T-shaped profile body 200. At the same time, an inner sealing gasket 24 is set between the inner surface of the inner sealing pressure plate 25 and the inner wall surface 142, and is fixed to the inner wall surface 142 of the plate 11 by two screws 28. It is also fixed to the end of the T-shaped profile body 200 by screws 26. Thus, the side wall 5 is installed.

[0039] Finally, a sealing layer 340 is applied to the surface of the inner valve base plate 1 of the side wall 5.

[0040] As described above, the connection between the SLRC material panels 11 on the side wall 5 of the prefabricated SLRC smart fire pump station water tank provided by this utility model adopts a novel double-seal structure. This structure mainly consists of a steel frame 21, fastening screws 28, an outer sealing gasket 23, an inner sealing gasket 24, and an inner sealing pressure plate 25. The steel frame 21, SLRC material panels 11, inner sealing gasket 24, and inner sealing pressure plate 25 form the first seal. The steel frame 21, SLRC material panels 11, and outer sealing gasket 23 form the second seal. Furthermore, unlike traditional fire pump stations where leakage requires extensive excavation and complete waterproofing of the entire water tank, the prefabricated SLRC smart fire pump station provided by this utility model only needs to identify the leak point, loosen the fastening screws 28 and 26, open the inner sealing pressure plate 25, and replace the inner sealing rubber 24 if leakage occurs under special circumstances. This not only ensures a good seal and extends service life but also facilitates replacement, features not found in water tanks of other fire pump station structures. Moreover, the pool is assembled on-site from SLRC material panels 11, fastened with bolts and sealed with gaskets. In particular, the side wall 5 of this utility model adopts the modified SLRC material structure of panel 1, which is a new type of reinforced concrete composite stainless steel material. It combines the excellent load-bearing capacity of reinforced concrete with the corrosion resistance of stainless steel. By using prefabricated SLRC material and adopting an assembly construction process on-site, the construction cycle is greatly shortened, construction costs are reduced, and installation and maintenance are also very convenient.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
