Technical Field

[0001] The utility model relates to an underground tank manufactured by a rotational molding process, in particular to an assembled all-plastic underground tank. Background Art

[0002] Underground tanks are usually buried underground and can be used as sewage storage tanks or interception tanks. With the continuous development and maturity of the roto-molding manufacturing process, existing underground tanks are also manufactured by roto-molding to become all-plastic underground tanks. They are widely used due to their advantages such as convenient manufacturing, light weight, corrosion resistance, and long service life. However, traditional underground tanks are all integrally roto-molded. As the application volume of underground tanks increases, their volume also becomes very large, which brings great inconvenience to the roto-molding manufacturing and storage and transportation of underground tanks. At the same time, the outer surface of the roto-molded one-piece underground tank will be designed with reinforcement grooves or reinforcement ribs to enhance the structural strength. Since these reinforcement structures are designed on the outer surface of the underground tank, that is, these reinforcement structures are all external reinforcements of the underground tank, but there are few internal support reinforcements through other structures. Therefore, it is difficult for an overly large underground tank to achieve sufficient structural strength by relying solely on the reinforcement of the external rib grooves, which affects normal use.

This embodiment can design the underground tank as follows Figure 7 , Figure 8 The vertical tank shown in the figure can also be designed as an underground tank Fig.11 , Fig.12 The structure of the horizontal tank shown in the figure is composed of a reinforcement frame 1 and an assembled tank body 2 which is assembled and enclosed outside the reinforcement frame.

[0033] The reinforcement frame 1 is a column-type frame structure composed of two reinforcement rings 11 and a plurality of reinforcement rods 12 respectively connecting the two reinforcement rings; and, one of the reinforcement rings 11 is a circle with a "┓"-shaped cross section, and the other reinforcement ring 11 is a circle with a "Z"-shaped cross section. The buried tank in this embodiment is a vertical tank, then the reinforcement ring 11 at the top has a "┓"-shaped cross section, and the reinforcement ring 11 at the bottom has a "Z"-shaped cross section, and the reinforcement rod 12 is a straight rod with a "Z"-shaped cross section. The number of the reinforcement rods 12 needs to be selected according to the size of the reinforcement frame 1. In this embodiment, Fig. 9 , Fig.10 As shown, three reinforcement rods 12 evenly distributed around the circumference are designed to connect the two reinforcement rings 11 respectively, thereby forming a cylindrical frame structure.

[0034] The assembled tank body 2 includes end covers respectively covered and fixed on two reinforcement rings 11 and a middle shell 22 circumferentially surrounded by the periphery of the reinforcement frame 2; wherein, when the local buried tank is a vertical tank, the end cover at the top is a spherical cover 21, and the end cover at the bottom is a plane cover 23, and the plane cover is mainly fixedly installed with the reinforcement ring 11 through a plurality of reinforcement holes 232 evenly distributed on the periphery; when the local buried tank is a horizontal tank, both end covers are spherical covers 21.

[0035] The middle shell 22 is formed by a plurality of arc-surface covers 221 which are joined in a circle. A arc-surface cover 221 is provided between each two adjacent reinforcement rods 12. When the buried tank is a vertical tank, four arc-surface covers 221 are required to be joined in a circle to form a cylindrical shape. When the buried tank is a horizontal tank, the cylindrical shape formed by the four arc-surface covers 221 can be taken as a group. Then, only a plurality of groups need to be axially spliced ​​in sequence to lengthen the tank body. Of course, this lengthening splicing structure is also applicable to vertical tanks.

[0036] The two side surfaces of each curved cover 221 are respectively fixed to two adjacent reinforcement rods 12. The specific structure is: the two side surfaces of the curved cover 221 are respectively set as step surfaces 24, and the curved cover 221 is fitted and fixed on the reinforcement rod 12 through the step surfaces 24, so the reinforcement rod is just fitted and fixed between the step surfaces 24 of the two adjacent curved covers 221.

[0037] At the same time, an extruder hot-melt welding rod 3 is also provided between the step surfaces 24 of the two sides of the adjacent two curved cover 221, and the reinforcing rod 12 is hot-melted and wrapped therein by the extruder hot-melt welding rod.

[0038] The two end surfaces of each arc cover 221 are respectively fixed to two reinforcement rings 11, and the specific structure is: the inner surface of the spherical cover 21, the inner surface of the plane cover 23 and the two end surfaces of the arc cover 221 are all set as step surfaces 24, then the reinforcement ring 11 with a "┓"-shaped cross section will be fitted and fixed between the step surfaces 24 of the spherical cover 21 and the arc cover 221, and the reinforcement ring 11 with a "Z"-shaped cross section will be fitted and fixed between the step surfaces 24 of the plane cover 23 and the arc cover 221.

[0039] An extruder hot-melt welding rod 3 is provided between the step surfaces 24 of the spherical cover 21 and the arc cover 221, and the reinforcement ring 11 with a "┓"-shaped cross-section is hot-melted and wrapped inside by the extruder hot-melt welding rod; an extruder hot-melt welding rod 3 is provided between the step surfaces 24 of the flat cover 23 and the arc cover 221, and the reinforcement ring 11 with a "Z"-shaped cross-section is hot-melted and wrapped inside by the extruder hot-melt welding rod.

[0040] In addition, if the buried tank is a vertical tank, a lifting ring 13 is provided on the reinforcement ring 11 at the top; if the buried tank is a horizontal tank, lifting rings 13 are provided on both reinforcement rings 11. These lifting rings extend out of the end cover to facilitate lifting of the buried tank.

[0041] The lifting ring 13 is usually arranged at the connection between the reinforcement ring 11 and the reinforcement rod 12. If three reinforcement rods 12 are designed in this embodiment, three lifting rings 13 are designed at the corresponding positions on the reinforcement ring 11.

When the buried tank is a vertical tank, the spherical cover 21 is provided with a tank mouth 211 located in the middle and a plurality of reserved installation platforms 212 evenly distributed around the circumference with the tank mouth as the center; when the buried tank is a horizontal tank, the spherical cover 21 is provided with reserved installation platforms 212 in the middle and the periphery, but the tank mouth 211 is designed on the curved cover 221.

[0043] The outer surface of the spherical cover 21 is provided with a plurality of solid vertical ribs 213 which are evenly distributed in a radial shape. One end of each solid vertical rib extends to the tank mouth 211, and the other end extends to the bottom of the spherical cover. The outer surface of the spherical cover 21 is also provided with solid annular ribs 214 which are arranged in concentric circles with the tank mouth 211 as the center.

[0046] In this way, the underground tank assembled by the assembled tank body 2 in combination with the reinforcement frame 1 can not only perform rotational molding, storage and transportation of the assembled tank bodies separately, thereby reducing the various costs incurred, but also facilitate rapid assembly and lifting on the construction site. The external reinforcement structure provided on the outer surface of the assembled tank and the internal support reinforcement of the reinforcement frame 2 can also greatly enhance the structural strength of the entire underground tank and avoid affecting normal use.

[0047] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
