Description

Technical Field

[0001] The utility model relates to the technical field of underground liquor storage, in particular to a sealing structure for underground liquor storage. Background Art

[0002] In the traditional storage and aging process of liquor, underground storage is a widely used method. The underground environment can effectively maintain the stable quality and flavor of liquor due to factors such as constant temperature, moderate humidity, and insufficient light.

[0003] The traditional way to store liquor is to bury the container halfway underground. Specifically, half of the container is buried underground, while the other half is exposed above the ground. The container mouth is sealed with cement sealing technology, and a wax layer is applied on it to enhance the sealing performance. After that, a shrink film is used for secondary sealing, and then a layer of cement is covered for final sealing. Although this traditional sealing method can protect liquor to a certain extent, there are some significant problems in practical application.

[0004] First, this sealing method makes it very difficult to unseal the container mouth. When the storage time is long (such as more than 5 years), disassembling the container requires destroying the sealing layer, which is complicated and time-consuming, seriously affecting the convenience of taking the liquor. Secondly, since the surface of the sealed container is usually smooth, there is a lack of sufficient force-bearing positions during the transportation and placement process, making it very difficult to transport large quantities of liquor. This design is not only not conducive to efficient storage operations, but also increases the safety hazards of operations.

[0005] It is necessary to design a new sealing structure for underground storage of liquor. The structure should have an easy-to-operate unsealing design and provide a reasonable force position on the container surface to facilitate handling and storage operations. At the same time, the sealing structure should also maintain excellent sealing performance to ensure that the liquor can fully maintain its flavor and quality during storage. Utility Model Content

[0006] The purpose of the utility model is to provide a sealing structure for underground storage of liquor to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A sealed structure for underground storage of liquor, comprising:

[0009] Storage tank, an annular protrusion is provided on the outer side of the open end at the top of the storage tank, a sealing cover is snap-fitted to the top end of the storage tank, a plurality of first threaded holes are equidistantly and uniformly opened on the side of the top of the sealing cover, the sealing cover is threadedly connected with fastening bolts through the first threaded holes, and second threaded holes corresponding to the positions and numbers of the first threaded holes are opened on the annular protrusion, and the second threaded holes are threadedly connected with the fastening bolts;

[0010] A nut is threadedly connected to the outer wall of the fastening bolt, a plurality of layers of sealing films are arranged between the top of the inner part of the sealing cover and the top opening of the storage tank, and longitudinal handles are fixedly installed on both sides of the top of the sealing cover.

[0012] Preferably, the limiting hoop comprises two arc-shaped limiting members, connecting blocks are fixedly installed on both sides of the arc-shaped limiting members, and the two arc-shaped limiting members are fixedly connected through the cooperation of the connecting blocks and bolts.

[0013] Preferably, the clamping groove comprises a rectangular groove and a trapezoidal groove, the rectangular groove is located on the outer side of the trapezoidal groove, and the height of the rectangular groove is adapted to the total height of the first annular positioning member and the second annular positioning member.

[0014] Preferably, a transverse handle is fixedly installed between the two longitudinal handles.

[0015] Preferably, a plurality of anti-slip grooves are opened on the outer walls of the longitudinal handle and the transverse handle.

[0016] Preferably, the storage tank and the annular protrusion are of an integrally formed structure.

[0017] Preferably, the number of the fastening bolts is four.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model, through the combined use of a storage tank, a sealing cover, a longitudinal handle, a transverse handle, fastening bolts, a first threaded hole, a second threaded hole, nuts, an annular protrusion, and a multi-layer sealing film, is equipped with a sealing cover at the top of the storage tank. The sealing cover is firmly fixed at the opening of the storage tank through a plurality of fastening bolts. To ensure the sealing effect, a multi-layer sealing film is used at the connection between the sealing cover and the storage tank. This multi-layer design enhances the sealing performance, effectively preventing the penetration of air and moisture, and ensuring the quality stability of the baijiu during storage. During the handling process, to improve the convenience of operation, two handles are provided on the top of the sealing cover: a longitudinal handle and a transverse handle. These handles provide reasonable force-bearing positions, making it safer and more efficient to handle the storage tank. Operators can directly grasp and move the storage tank through these handles, avoiding the handling difficulties caused by the lack of a force-bearing point. When it is necessary to take out the baijiu, simply remove the fastening bolts on the sealing cover, and the sealing cover can be easily removed without any damage to the sealing structure.

[0031] Please refer to Figures 1 - 5 , an embodiment provided by the present utility model:

[0032] A sealed structure for underground storage of liquor, which includes:

[0033] Storage tank 1, an annular protrusion 17 is provided on the outer side of the open end at the top of the storage tank 1. A sealing cover 2 is clamped at the top end of the storage tank 1. A plurality of first threaded holes 12 are equidistantly and evenly opened on the side of the top of the sealing cover 2. The sealing cover 2 is threadedly connected with fastening bolts 6 through the first threaded holes 12. Second threaded holes 15 corresponding to the positions and quantities of the first threaded holes 12 are opened on the annular protrusion 17, and the second threaded holes 15 are threadedly connected with the fastening bolts 6;

[0034] A nut 16 is threadedly connected to the outer wall of the fastening bolt 6. A multi-layer sealing film 18 is provided between the top of the inner part of the sealing cover 2 and the top opening of the storage tank 1. Longitudinal handles 3 are fixedly installed on both sides of the top of the sealing cover 2.

[0035] A first annular positioning member 13 is fixedly installed on the outer side of the sealing cover 2, and a second annular positioning member 14 is fixedly installed on the outer side of the annular protrusion 17. A limiting hoop 5 is provided on the outer surfaces of the second annular positioning member 14 and the first annular positioning member 13. A clamping groove 9 is opened on the inner surface of the limiting hoop 5, and the limiting hoop 5 is clamped with the first annular positioning member 13 and the second annular positioning member 14 through the clamping groove 9.

[0036] In one embodiment, the limiting hoop 5 includes two arc-shaped limiting members 8. Connecting blocks 7 are fixedly installed on both sides of the arc-shaped limiting members 8. The two arc-shaped limiting members 8 are fixedly connected through the cooperation of the connecting blocks 7 and bolts, making the installation and disassembly of the limiting hoop 5 more convenient. The method of fixing with bolts makes the adjustment and maintenance work more convenient, and the operation can be completed only by loosening or tightening the bolts.

[0037] In one preferred embodiment, the clamping groove 9 includes a rectangular groove 10 and a trapezoidal groove 11. The rectangular groove 10 is located on the outer side of the trapezoidal groove 11. The height of the rectangular groove 10 is adapted to the total height of the first annular positioning member 13 and the second annular positioning member 14. The combined design of the rectangular groove 10 and the trapezoidal groove 11 can ensure the accurate alignment of the components during assembly and improve the connection firmness.

[0038] In one embodiment, a transverse handle 4 is fixedly installed between the two longitudinal handles 3, enabling the operator to lift the storage tank 1 with both hands through the two longitudinal handles 3 or lift the storage tank 1 with one hand through the transverse handle 4, providing multiple handling modes for the operator and improving the handling efficiency.

[0039] In one preferred embodiment, a plurality of anti-slip grooves are opened on the outer walls of the longitudinal handle 3 and the transverse handle 4. The design of the anti-slip grooves can significantly improve the stability of the user when grasping the longitudinal handle 3 and the transverse handle 4. The anti-slip grooves provide additional friction, reduce the possibility of slipping of the hand, and make the operation safer and more reliable.

[0040] In one embodiment, the storage tank 1 and the annular protrusion 17 are of an integrally formed structure. The integrally formed design eliminates the connection gap between the storage tank 1 and the annular protrusion 17, making the entire structure stronger and capable of withstanding greater pressure and load.

[0041] In one preferred embodiment, the number of fastening bolts 6 is four. The four fastening bolts 6 can be more evenly distributed between the sealing cover 2 and the storage tank 1, so that the force is more evenly distributed, reducing local stress concentration. This helps to improve the overall stability of the sealing cover 2 and avoid the decline of the sealing effect or structural damage caused by uneven force.

[0042] The working principle of the present utility model is as follows: The parts not involved in this device are the same as or can be implemented by the prior art. When storing liquor in the storage tank 1, the liquor is poured through the top opening of the storage tank 1, and then the sealing cover 2 is covered on the top opening of the storage tank 1, aligning the first threaded hole 12 on the sealing cover 2 with the second threaded hole 15 on the annular protrusion 17. At the same time, the fastening bolts 6 are sequentially screwed into the interiors of the first threaded hole 12 and the second threaded hole 15, and the bottom end of the fastening bolt 6 extends below the bottom of the annular protrusion 17. Then, the nut 16 is tightened from the bottom end of the fastening bolt 6 to firmly fix the sealing cover 2 at the top opening of the storage tank 1. A sealing cover 2 is equipped at the top of the storage tank 1, and the sealing cover 2 is firmly fixed at the opening of the storage tank 1 by a plurality of fastening bolts 6. To ensure the sealing effect, a multi-layer sealing film 18 is adopted at the connection between the sealing cover 2 and the storage tank 1. This multi-layer design enhances the sealing performance, effectively preventing the penetration of air and moisture and ensuring the quality stability of the liquor during storage; during handling, to improve the operation convenience, two handles are provided on the top of the sealing cover 2: the longitudinal handle 3 and the transverse handle 4. These handles provide reasonable force application positions, making it safer and more efficient to handle the storage tank 1. The operator can directly grab and move the storage tank 1 through these handles, avoiding the handling difficulty caused by the lack of a force application point; when liquor needs to be taken, only the fastening bolts 6 on the sealing cover 2 need to be disassembled, and then the sealing cover 2 can be easily removed without any damage to the sealing structure. This design improves the convenience of taking liquor, simplifies the operation process, and ensures that the quality of the liquor during storage is not affected.

[0043] After the sealing cover 2 is fixed to the top of the storage tank 1 by fastening bolts 6, two arc-shaped limit members 8 can then be engaged with the outer walls of the first annular positioning member 13 and the second annular positioning member 14 through the clamping grooves 9, and the connecting blocks 7 at both ends of the arc-shaped limit member 8 are locked and fixed by bolts, so that the limit hoop 5 is firmly clamped on the outer walls of the first annular positioning member 13 and the second annular positioning member 14, further improving the firmness of the sealing cover 2 fixed to the top of the storage tank 1. In addition, during the process of the limit hoop 5 positioning the first annular positioning member 13 and the second annular positioning member 14, the first annular positioning member 13 and the second annular positioning member 14 will enter the interior of the trapezoidal groove 11 through the rectangular groove 10 on the clamping groove 9, and the trapezoidal groove 11 will generate a squeezing force on the first annular positioning member 13 and the second annular positioning member 14, so that the first annular positioning member 13 and the second annular positioning member 14 are fixed more tightly under the limitation of the limit hoop 5, which is beneficial to improving the sealing effect of the sealing cover 2 on the top opening of the storage tank 1 through the multi-layer sealing film 18.

[0044] It should be noted that in the actual production process of the underground storage sealing structure of Baijiu of the present utility model, all components are subjected to anti-corrosion treatment to ensure their durability and stability during long-term use. The anti-corrosion technology used belongs to the prior art, so it will not be described in detail in this text.

[0045] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and do not limit the present utility model.
