[0002] When transporting liquid goods such as liquor, oil, liquid food, chemical drugs, etc., it is usually carried out by filling the liquid goods in a tank container for transportation.

[0003] In the existing tank container, a manhole is usually arranged at the top of the tank body for the operator to enter the inside of the tank body for inspection and maintenance, and a top discharge hole for filling and unloading liquid goods is arranged. A detachable manhole cover is arranged on the manhole, and a detachable top discharge blind cover is arranged on the top discharge hole. The manhole cover and the top discharge blind cover are usually connected to the manhole and the top discharge hole respectively by flanges. Due to the flange connection, the manhole cover and the top discharge blind cover protrude from the top of the tank body respectively, and the opening of the top discharge hole is located above the tank body.

[0004] However, when it is necessary to fill or unload the liquid inside the tank body, it is necessary to remove the top discharge blind cover and install a top discharge valve on the top discharge hole. When the space at the top of the tank container is small, due to the opening of the top discharge hole being located above the tank body, the installation space of the valve at the top of the tank container is limited. In addition, the separate design of the top discharge hole and the manhole increases the number of openings in the tank body and reduces the reliability of the tank body. Summary of the Utility Model

[0005] Aiming at the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide a tank container, which can meet the installation space of the valve at the top of the tank container when the space at the top is small.

A top discharge hole is arranged on the manhole cover, and a top discharge blind cover for covering the top discharge hole is connected to the top discharge hole.

[0008] Further, a gas phase valve and a safety valve are arranged on the manhole cover.

[0009] Furthermore, an overflow box is arranged at the top of the tank body, and the manhole is arranged in the overflow box.

[0010] Still further, a raised liquid collecting ring is arranged around the edge of the manhole, and a drainage hole for liquid to flow out is arranged on the liquid collecting ring.

[0011] Furthermore, the overflow box includes an overflow ring protruding upward at the top of the tank body and a liquid guiding mechanism connected to the overflow ring. The overflow ring is concentric with the liquid collecting ring, and the center of the liquid collecting ring and the drainage hole are both located on the same radial section of the tank body.

[0012] Furthermore, the overflow ring is provided with liquid guiding holes, and the liquid guiding holes are connected to the liquid guiding mechanism. The center of the overflow ring and the liquid guiding holes are both located on the same radial section of the tank body.

[0013] Furthermore, the manhole cover is provided with lifting eye bolts.

[0014] Furthermore, there are two lifting eye bolts, and each lifting eye bolt is arranged at the same-side edge of the manhole cover, and each lifting eye bolt is arranged oppositely based on the center of the manhole cover.

[0015] Furthermore, the tank body is provided with a gas phase valve and a safety valve.

[0016] Furthermore, a reinforcing ring is arranged outside the tank body, and the reinforcing ring is coaxially arranged with the tank body.

[0028] As Figures 1 to 3As shown in the figure, the utility model discloses a tank container, which is mainly used for storing liquids. The tank container includes a manhole 2 arranged at the top of the tank body 1. The manhole 2 is circular, and the plane where the opening of the manhole 2 is located is lower than the highest point of the tank body 1 from the ground. Specifically, the tank body 1 is a cylindrical tank, the axis of the tank body 1 is arranged parallel to the horizontal plane, and the opening plane of the manhole 2 is parallel to the horizontal plane. A manhole cover 3 for covering the manhole 2 is connected to the manhole 2. Specifically, bolt holes are arranged around the manhole 2 on the tank body 1. The manhole cover 3 is also circular, and bolt holes are also arranged at the edge of the manhole cover 3. The manhole cover 3 and the manhole 2 are connected by bolts. When operators need to enter the interior of the tank body, the bolts connecting the manhole cover 3 and the tank body 1 are removed, so as to remove the manhole cover 3 from the tank body 1. A top discharge hole is arranged on the manhole cover 3, and a top discharge blind cover 4 for covering the top discharge hole is connected to the top discharge hole. Specifically, the top discharge blind cover 4 and the manhole cover 3 are also connected by bolts. By removing the top discharge blind cover 4, liquid filling operation can be carried out inside the tank body 1. The utility model sets the plane where the opening of the manhole 2 is located lower than the highest point of the tank body 1 from the ground, and arranges the top discharge hole on the manhole cover 3, and connects the top discharge blind cover 4 to the top discharge hole, so that the plane where the opening of the top discharge hole is located is also lower than the highest point of the tank body 1 from the ground. When the space at the top of the tank container is small, the installation space for the valves at the top of the tank container is satisfied. At the same time, the integrated design of the top discharge hole and the manhole cover 3 reduces the number of openings on the tank body 1 and improves the reliability of the tank body 1.

[0029] In this embodiment, as Figure 2 and Figure 4 shown, a gas phase valve 5 and a safety valve 6 are arranged on the manhole cover 3. Specifically, a gas phase valve hole and a safety valve hole are opened on the manhole cover 3. The gas phase valve 5 is connected to the gas phase valve hole by bolts, and the safety valve 6 is also connected to the safety valve hole by bolts. The utility model arranges both the gas phase valve 5 and the safety valve 6 on the manhole cover 3, so that there is no need to additionally open holes on the tank body 1 to fix the gas phase valve 5 and the safety valve 6, further reducing the number of openings on the tank body 1 and further improving the reliability of the tank body 1. Moreover, the integrated design of the gas phase valve 5, the safety valve 6 and the manhole cover 3 helps to realize the integrated disassembly of the gas phase valve 5 and the safety valve 6, facilitating the maintenance of the gas phase valve 5 and the safety valve 6.

[0030] In other embodiments, the top discharge blind cover 4 is still arranged on the manhole cover 3, but the vapor valve 5 and the safety valve 6 are arranged on the tank body 1. Specifically, two mounting holes are opened on the tank body 1, and the vapor valve 5 and the safety valve 6 are respectively welded to the two mounting holes. By arranging the vapor valve 5 and the safety valve 6 on the tank body 1, the size of the manhole 2 can be reduced, or the size of the top discharge hole can be increased, thereby improving the liquid filling and liquid unloading efficiency.

[0031] In this embodiment, an overflow box is arranged at the top of the tank body 1, and the manhole 2 is arranged in the overflow box. By arranging the overflow box, when the liquid filling operation is carried out on the tank container, the liquid overflowing from the tank body 1 is located in the overflow box, avoiding the overflowing liquid from polluting the tank body 1. And, since the vapor valve 5 and the safety valve 6 are both arranged on the manhole cover 3, the size of the overflow box can also be reduced. Thus, when the surface of the tank body 1 is covered with heat insulation cotton, except for the overflow box, other areas of the tank body 1 can be covered by the heat insulation cotton, and the covering area of the heat insulation cotton is expanded due to the reduction of the overflow box, improving the heat insulation effect on the tank body 1. In other embodiments, in order to reduce the production cost of the tank container, the overflow box may not be arranged either.

[0032] In this embodiment, as Figure 2 shown, a raised liquid collecting ring 7 is arranged around the edge of the manhole 2, and a drainage hole 8 for liquid to flow out is arranged on the liquid collecting ring 7. By arranging the liquid collecting ring 7, the liquid overflowing from the top discharge hole during the liquid filling process will not flow randomly to any corner in the overflow box, but can only flow to a fixed position in the overflow box through the drainage hole 8, facilitating the collection of the overflowing liquid. In other embodiments, in order to reduce the production cost of the tank container, the liquid collecting ring 7 may not be arranged either.

[0033] In this embodiment, as Figure 2 and Figure 5 shown, the overflow box includes an overflow ring 9 protruding upward at the top of the tank body 1 and a liquid guiding mechanism connected to the overflow ring 9. The overflow ring 9 is concentric with the liquid collecting ring 7, and the center of the liquid collecting ring 7 and the drainage hole 8 are both located on the same radial section of the tank body 1. Since the axis of the tank body 1 is parallel to the horizontal plane and the tank body 1 is usually arranged on the horizontal ground, thus as Figure 5As shown, the overflow ring 9 and the tank body 1 form a receiving groove with an arc-shaped bottom surface. The manhole 2 is located at the top of the receiving groove. The liquid overflowing from the manhole 2 will flow into the receiving groove and finally flow to the bottom of the receiving groove under the influence of gravity. The drainage hole 8 is arranged towards the bottom of the receiving groove. Therefore, by defining the position of the drainage hole 8 in the present utility model, the liquid flowing out from the drainage hole 8 can quickly flow to the bottom of the receiving groove, facilitating the collection of the overflow liquid during the filling operation. In other embodiments, the drainage hole 8 can also be arranged at other positions, but the technical effect is not as good as the technical solution of this embodiment.

[0034] In this embodiment, the overflow ring 9 is provided with a liquid guiding hole, which is connected to the liquid guiding mechanism. The center of the overflow ring 9 and the liquid guiding hole are both located on the same radial section of the tank body 1, that is, the liquid guiding hole is arranged at the bottom of the receiving groove. By defining the position of the liquid guiding hole in the present utility model, it is convenient to quickly guide the overflow liquid out of the receiving groove and reduce the risk of the overflow liquid accumulating. In other embodiments, the liquid guiding hole can also be arranged at other positions, but the technical effect is not as good as the technical solution of this embodiment.

[0035] In this embodiment, as Figure 2 and Figure 4 shown, the manhole cover 3 is provided with lifting eye bolts 10. Since the tank body 1 is relatively large and the manhole cover 3 is relatively heavy, by providing the lifting eye bolts 10, it is convenient to connect an external crane to the lifting eye bolts 10 during the process of removing the manhole cover 3, so as to lift the manhole cover 3, achieving the effect of facilitating the disassembly and assembly of the manhole cover 3. In other embodiments, in order to reduce the production cost of the tank container, the lifting eye bolts 10 may not be provided.

[0036] In this embodiment, as Figure 2 and Figure 4 shown, there are two lifting eye bolts 10, and each lifting eye bolt 10 is arranged at the same-side edge of the manhole cover 3, and each lifting eye bolt 10 is arranged oppositely based on the center of the manhole cover 3. By defining the number and position of the lifting eye bolts in the present utility model, the manhole cover 3 can be lifted smoothly during the process of the external crane lifting the manhole cover 3. In other embodiments, the number of the lifting eye bolts 10 can also be set to at least three, and each lifting eye bolt 10 is arranged at the same-side edge of the manhole cover 3, and the intervals between the lifting eye bolts 10 are equally spaced.

[0037] In this embodiment, as Figure 1As shown, a reinforcing ring 11 is provided outside the tank body 1, and the reinforcing ring 11 is arranged coaxially with the tank body 1. By providing the reinforcing ring 11 in the present utility model, the reinforcement of the tank body 1 is realized, and the possibility of deformation of the tank body 1 due to insufficient strength of the tank body when the tank body 1 is filled with liquid is reduced. In other embodiments, in order to reduce the production cost of the tank container, the reinforcing ring 11 may not be provided.

[0038] In summary, for the tank container of the present utility model, by setting the plane where the opening of the manhole 2 is located lower than the highest point of the tank body 1 from the ground, when the space at the top of the tank container is small, the installation space for the valves at the top of the tank container is satisfied. At the same time, the integrated design of the top discharge hole and the manhole cover 3 reduces the number of openings on the tank body 1 and improves the reliability of the tank body 1. By arranging both the gas phase valve 5 and the safety valve 6 on the manhole cover 3, it is not necessary to additionally open holes on the tank body 1 to fix the gas phase valve 5 and the safety valve 6, reducing the number of openings on the tank body 1 and further improving the reliability of the tank body 1. Moreover, the integrated design of the gas phase valve 5, the safety valve 6 and the manhole cover 3 helps to realize the integrated disassembly of the gas phase valve 5 and the safety valve 6. Or by arranging both the gas phase valve 5 and the safety valve 6 on the tank body 1, the size of the manhole 2 can be reduced, or the size of the top discharge hole can be increased, thereby improving the liquid filling and liquid unloading efficiency. At the same time, for the tank container of the present utility model, through the setting of the overflow box, when the tank container is performing liquid filling operation, the liquid overflowing from the tank body 1 is located in the overflow box, avoiding the overflowing liquid from contaminating the tank body 1. And because both the gas phase valve 5 and the safety valve 6 are arranged on the manhole cover 3, the size of the overflow box can also be reduced, and the coverage area of the heat preservation cotton is enlarged. Through the setting of the liquid collecting ring 7, the liquid overflowing from the top discharge hole during the liquid filling process will not flow randomly to any corner of the overflow box, facilitating the collection of the overflowing liquid. By defining the position of the drainage hole 8, the liquid flowing out from the drainage hole 8 can quickly flow to the bottom of the receiving groove, facilitating the collection of the overflowing liquid during the filling operation. By defining the position of the liquid guiding hole, it is convenient to quickly guide the overflowing liquid out of the receiving groove and reduce the risk of accumulation of the overflowing liquid. By providing the lifting eye screw 10, it is convenient to disassemble and assemble the manhole cover 3. By defining the number and position of the lifting eye screws, when the external crane lifts the manhole cover 3, the manhole cover 3 can be lifted smoothly. By providing the reinforcing ring 11, the reinforcement of the tank body 1 is realized.

[0039] It should be emphasized that the above are only the preferred embodiments of the present utility model, and there is no restriction on the present utility model in any form. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
