[0033] In order to further explain the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.

[0034] Example 1

[0035] A vertical assembled tank body micro-point type top cover, comprising a support structure 5 fixedly connected with the top of a tank body 1 and a tank top 3 arranged on the support structure 5; the tank top 3 is conical, and a vent pipe assembly 4 for connecting the inside of the tank body 1 with the atmosphere is arranged at the center of the tank top 3; the support structure 5 is matched with the tank top 3.

[0036] As Figure 2 ​​​​As shown, the venting pipe assembly 4 includes a venting bend 41 with a flange on it and a central pipe 42 with a flange. The two flanges are fixed with bolts and nuts, so that the inside of the tank 1 can be vented to the outside of the tank.

[0037] The supporting structure 5 includes a central pipe 42 located at the center of the tank 1 and four main beams 51 fixedly connected to the central pipe 42 at one end. The number of main beams 51 is determined according to the diameter of the tank 1. Generally, for a tank 1 with a diameter of less than 12 meters, four main beams 51 are used. If the diameter is greater than 12 meters, the number of main beams 51 needs to be increased. For a tank 1 with a diameter of 16 meters, six main beams 51 are evenly distributed. For a tank 1 with a diameter of 20 meters, eight main beams are evenly distributed.

[0038] The four main beams 51 are evenly distributed around the circumference of the central tube 42; the other end of the main beam 51 is fixedly connected to the tank body 1; the tank top 3 is fixedly connected to the main beam 51.

[0039] like Figure 1 As shown, the angle between the main beam 51 and the horizontal plane is θ, which is 7-15 degrees. The smaller the angle, the flatter the tank top 1 is, which is not conducive to the sliding of rain and snow. The larger the angle, the larger the area of ​​the tank top 1 and the amount of supporting components required, which is uneconomical. After repeated calculations, we chose θ as 8 degrees, which can both allow rain and snow to slide down and minimize the area of ​​the tank top 1 and the amount of supporting components required.

[0040] like Figure 6 As shown, two adjacent main beams 51 are arranged at a 90-degree angle;

[0041] The supporting structure 5 also includes a support beam 33 disposed between adjacent main beams 51;

[0042] One end of the support beam 33 is fixed to the tank body 1, and the other end is fixed to the main beam 51;

[0043] There are three support beams 33 between two adjacent main beams 51; each support beam 33 is parallel to one of the main beams 51 and parallel to each other. The spacing between the support beams 33 is about 800mm; if the spacing is too large, the support strength will be insufficient, and if the spacing is too small, steel will be wasted. The number of support beams 33 is determined according to the diameter of the tank 1 and the spacing of the main beams 51. For a 6-meter tank, three support beams 33 are sufficient.

[0044] To increase connection strength and the stability of the supporting structure, such as Figure 6 As shown, connecting rods 32 are provided between adjacent support beams 33 and between the main beam 51 and its adjacent support beams 33.

[0045] The tank top 3 is fixedly connected to the support beam 33 and the main beam 51 respectively.

[0046] To increase the stability of tank top 3, such asFigure 3 As shown in the drawings, the vertical plate 34 is welded on the main beam 51, and the channel-shaped connecting plate 31 is fixedly connected with the vertical plate 34 by bolts and nuts, and the tank top 3 is fixedly connected with the channel-shaped connecting plate 31 by self-tapping screws.

[0047] As shown in the drawings, Figure 2 As shown in the drawings, the vertical fixed plate 53 is welded on the center pipe 42, and one end of the main beam 51 is fixedly connected with the vertical fixed plate 53 by bolts and nuts.

[0048] The inner wall of the tank body 1 is welded with the fixed sleeve 11 near the top, and the other end of the main beam 51 is fixedly connected with the support 13 by bolts, and the pin shaft 12 is welded on the support 13; the pin shaft 12 is inserted into the fixed sleeve 11. In this way, the other end of the main beam 51 is connected with the tank body 1, and since it is connected in a split manner, the installation is relatively convenient.

[0049] The outer wall of the tank body 1 is fixedly connected with the stand 2 near the top, and the edge part of the tank top 3 is fixedly connected with the stand 2. The stand 2 comprises the hoop angle steel fixed around the tank body 1 and the support angle steel fixed with the hoop angle steel; the support angle steel is fixed with the tank top 3 by bolts and nuts.

[0050] During the manufacture of the tank top 3, a vertical column is first arranged in the center of the tank body 1 to support the center pipe 42, and the height of the center pipe 42 is higher than the top of the tank body 1, and then the one end of the main beam 51 is fixed with the vertical fixed plate 53 on the center pipe 42 by bolts and nuts.

[0051] The other end of the main beam 51 is installed with the support 13, and then the pin shaft 12 is inserted into the fixed sleeve 11, and the main beam 51 is lapped, and then the one end of the support beam 33 is connected with the tank body 1 in the same manner as the main beam 51, and the other end of the support beam 33 is fixed with the main beam 51; and then the outer edge of the tank top 3 is fixed with the stand 2. The tank top 3 is fixed with the main beam 51 and the support beam 33 in the middle, and the center of the tank top 3 is sealingly fixed with the center pipe 42.

[0052] Example 2

[0053] As shown in the drawings, Figure 3

[0054] The vertical plate 34 is welded on the support beam 33, and the middle part of the tank top 3 is fixedly connected with the vertical plate 34 by the channel-shaped connecting plate 31 and bolts and nuts. The channel-shaped connecting plate 31 adopts a channel shape, which can reduce the thickness of the steel plate as much as possible to ensure the strength of the connecting plate 31, thereby increasing the stability of the tank top 1.

[0055] Example 3

[0056] ​In the embodiment 1, the fixing sleeve 11 is directly welded on the tank body 1. Since the tank body 1 is generally thin, the direct welding of the fixing sleeve 11 will cause the connecting part between the fixing sleeve 11 and the tank body 1 to be thin and weak, and deformation is easily caused, so it needs to be reinforced.

[0057] As shown in Figure 5 , the fixing sleeve 11 is welded on a plate 14 which is thick and large in area; the plate 14 is fixed with the tank body 1 through bolts and nuts, so the connection is firm and the tank body 1 is not easily deformed.

[0058] Embodiment 4

[0059] In order to increase the connecting strength of the main beam 51 and the center pipe 42, as shown in Figure 2 , a horizontal fixing plate 52 is welded on the center pipe 42; the horizontal fixing plate 52 is fixedly connected with the main beam 51. In this way, the sinking of the main beam 51 can be avoided.

[0060] Embodiment 5

[0061] In order to ensure the strength of the center pipe 42, as shown in Figure 7 , a cross reinforcing rib 43 is arranged in the center pipe 42, so that the center pipe 42 is not deformed.

[0062] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to make equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, change, equivalent change and modification of the above embodiments, which does not depart from the technical solution of the present application, is still within the scope of the present application.
