Description

Technical Field

[0001] The present application relates to the technical field of cellar safety protection, and in particular to a cellar protection net hook device. Background Art

[0002] In the production of Maotai-flavor liquor, fermentation is carried out in cellars with stone mud bottoms, and the depth of the cellars is usually 3.3m-3.6m. Cellar operations are limited space operations, and cellars are usually equipped with protective nets to prevent employees from accidentally falling into the cellars during operations. During the production process, protective nets must be laid when the cellar is opened and the mash is 1.5m above the ground or when the cellar is empty.

[0003] At present, most liquor companies usually use grooved cellar nail holes for hanging protective nets in their cellars. After the cellar top is poured, the cellar nails are cut with a cutting machine and then crushed with an electric hammer to form a groove. Then, holes with the same diameter as the cellar nails are drilled with an electric drill, and then the cellar nails are implanted in the holes. This method is easy to loosen during use. After loosening, the cellar nails are higher than the horizontal plane of the cellar top. Employees are prone to kicking their toes when walking on the cellar ridge, which poses a safety hazard. At the same time, the grooved cellar nail holes are open and have no sealing devices. The hygiene inside the cellar nail holes is extremely difficult to clean. Wine lees falling into them will cause food waste and fermented mash to mildew. After mildew, they will be mixed with normal fermented mash in the drying hall, which will contaminate the fermented mash and affect the quality of the base wine.

[0004] Therefore, it is urgent to provide a kind of pit protection net hook device to solve the technical problem proposed above. Utility Model Content

[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined with each other and quoted from each other without contradiction.

[0024] The following is a further detailed description of a cellar protection net hook device provided in this embodiment in conjunction with the accompanying drawings. Figure 1-Figure 5 As shown, it includes: a cellar top 1 cast on the top of the cellar, a plurality of circular cellar nail holes 2 are reserved on the cellar top 1, and a cellar nail 3 is embedded in each cellar nail hole 2; a protective net (not shown in the figure) is provided at the cellar mouth 11, hanging ropes are provided around the protective net, and the protective net is hung with the cellar nails 3 through the hanging ropes; a sealing device 4 is provided at the opening of the cellar nail hole 2.

[0025] In this embodiment, the implantation method of the cellar nail 3 is changed from the traditional drilling implantation to pre-embedding during the pouring of concrete on the cellar top 1. It is not easy to loosen or fall off during use, avoiding the risk of kicking toes due to the cellar nail 3 loosening and rising above the horizontal plane of the cellar top 1 and the hidden danger of failure of the protective net after the cellar nail 3 falls off; and the cellar nail hole 2 is changed from an open groove type to a closed cellar nail hole 2 sealed by a sealing device 4, which makes it more convenient to hang the protective net. More importantly, the change from an open type to a closed type can prevent the mash from being scattered therein, thereby solving the problems of food waste, mash moldy and contaminating other mash, and difficulty in cleaning. In this way, a protective net can be set above the cellar to prevent accidents such as falling people and falling objects.

[0026] Please continue to refer to Figure 1-Figure 5 As shown, in this embodiment, it should be noted that the sealing device 4 is configured as a sealing cover 41 , and the sealing cover 41 is nested in the cellar nail hole 2 , so that the cellar nail hole 2 is sealed by the sealing cover 41 .

[0027] In some embodiments, a side position of the sealing cover 41 is provided with an escape notch 411, and the escape notch 411 is used to escape the hanging rope. Since the cellar nail hole 2 is sealed by the sealing cover 41 in this embodiment, after the hanging rope is hung on the cellar nail 3, when the sealing cover 41 is nested in the cellar nail hole 2, the escape notch 411 can just escape the position of the hanging rope, so that the sealing cover 41 is conveniently nested in the cellar nail hole 2 without squeezing the hanging rope, so that the hanging rope can escape through the escape notch 411, and the sealing requirements of the sealing cover 41 are not affected. In addition, the escape notch 411 can also facilitate the operator to take out the sealing cover 41.

[0028] Please continue to refer to Figure 1-Figure 5 As shown, in this embodiment, it should be noted that the depth of the cellar nail hole 2 is set to at least 5 cm, and the diameter of the cellar nail hole 2 is set to 7 cm. The cellar nail 3 is set to a T-shape, the upper end width of the cellar nail 3 is 5 cm, the lower end length is 10 cm, and the lower end pre-embedded depth of the cellar nail 3 is set to be more than 5 cm. By setting the lower end pre-embedded depth of the cellar nail 3 to be more than 5 cm, the pre-embedded stability of the cellar nail 3 can be improved, and it is not easy to loosen or fall off during use. At the same time, the diameter of the cellar nail hole 2 is set to be slightly larger than the upper end width of the cellar nail 3, and the space between the two is large, which is convenient for hanging the protective net. In addition, the cellar nail 3 is set to a T-shape, which is convenient for the hanging rope to be hung on the upper end of the cellar nail 3.

[0029] Please continue to refer to Figure 1-Figure 5 As shown, in this embodiment, it should also be noted that the cellar nail 3 and / or the sealing cover 41 are both made of 304 food grade stainless steel.

[0030] Please continue to refer to Figure 1-Figure 5 As shown, in this embodiment, it should be noted that the cellar roof 1 is a reinforced concrete structure. The protective net is a nylon net with a mesh size of 50*50mm.

[0031] The implementation principle of this embodiment is as follows: a cellar pressure top 1 is cast on the top of the cellar, and a cellar nail hole 2 set in a circular shape is reserved on the cellar pressure top 1, a cellar nail 3 is pre-buried in the cellar nail hole 2, and then a protective net is set at the cellar mouth 11, and the pull ropes around the protective net are hung on the cellar nail 3 to tighten the protective net, and then the sealing cover 41 is buckled in the cellar nail hole 2, and the pull rope is avoided through the avoidance gap 411, so that a protective net can be set above the cellar to prevent accidents such as falling people and falling objects; at the same time, after the cellar nail 3 is implanted in a way that is changed to be pre-buried in advance, the loosening of the cellar nail 3 can be effectively reduced, thereby reducing the risk of kicking injuries and failure of the protective net; and after the open groove in the prior art is changed to a closed circular cellar nail hole 2, firstly, the protective net is hung more conveniently; secondly, it can reduce the scattering of mash into the cellar nail hole 2, reduce food waste, and avoid the contamination of other mash after the mash becomes moldy, so that basically no cleaning is required, reducing the workload of the team.

[0032] It should be understood that the above specific embodiments of the present application are only used to illustrate or explain the principles of the present application, and do not constitute a limitation to the present application. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present application should be included in the protection scope of the present application.
