Description

Technical Field

[0001] The utility model relates to a prefabricated stainless - steel confinement pen for a pig farm, belonging to the technical field of livestock breeding equipment. Background Art

[0002] The confinement pen is a commonly used breeding equipment in pig farms. Currently, the confinement pens in pig farms are usually integrally welded carbon - steel processed parts, which have the defect of inconvenient transportation. In addition, in order to prevent corrosion, the finished carbon - steel confinement pens in pig farms need to be transported to a hot - dip galvanizing plant for hot - dip galvanizing treatment to form a galvanized layer with anti - corrosion properties on the surface of the carbon - steel confinement pens. However, hot - dip galvanizing treatment will have an adverse impact on the environment and is not conducive to environmental protection. In addition, during the actual use of the hot - dip galvanized confinement pens, as the breeding time goes by, the galvanized layer on the outer surface will be rubbed off by pigs, resulting in the rusting of the confinement pens. In addition, with the raging of African swine fever, the large amount of disinfectant water used in pig farms is also corrosive to the galvanized layer on the outer surface of the confinement pens, which is also likely to cause the confinement pens to rust.

[0028] Embodiment

[0029] Please refer to Figures 1 to 8Shown as follows: A prefabricated stainless steel confinement pen for a pig farm provided in this embodiment includes two side fences 1, a front door 2, a rear door 3, and two feet 4. The front door 2 and the rear door 3 are respectively detachably connected to the front and rear ends of the side fence 1. The side fence 1, the front door 2, and the rear door 3 respectively include corresponding side fence bodies, front door bodies, and rear door bodies. The side fence bodies, front door bodies, and rear door bodies are all assembled by a plurality of pipe fittings through T-shaped clamps. The feet 4 are connected to the bottom of the side fence 1 body through T-shaped clamps 5. Moreover, the side fence 1, the front door 2, the rear door 3, the feet 4, and the T-shaped clamps are all made of QN series stainless steel.

[0030] As a preferred solution, the side fence 1, the front door 2, the rear door 3, the feet 4, and the T-shaped clamps are all made of QN1701 stainless steel. Because QN1701 stainless steel has excellent corrosion resistance and mechanical properties, its yield strength can reach the Q355 level. In addition, QN1701 stainless steel has excellent antibacterial functions, and the bactericidal rate against Escherichia coli and Staphylococcus aureus reaches more than 99.9%. Therefore, all components of the confinement pen in this embodiment are made of QN1701 stainless steel.

[0031] The usage method of the prefabricated stainless steel confinement pen for a pig farm described in this utility model is as follows:

[0032] Since the side fence bodies, front door bodies, and rear door bodies of the confinement pen are all assembled by a plurality of pipe fittings, and the pipe fittings are all connected through T-shaped clamps, and the side fence 1 and the feet 4 are connected through the T-shaped clamp 5. Therefore, during transportation, the components forming the side fence 1, the front door 2, the rear door 3, the feet 4, and the T-shaped clamp 5 can be directly transported to the construction site. Compared with directly transporting the finished confinement pen, the transportation of the confinement pen components is more convenient and occupies less transportation space.

[0033] After each component is transported to the construction site, according to the design requirements, each pipe fitting is assembled into the corresponding side fence body, front door body, and rear door body through T-shaped clamps, so as to obtain the prefabricated side fence 1, front door 2, and rear door 3. Then, the side fence 1 is detachably connected to the front door 2 and the rear door 3, and the side fence 1 and the feet 4 are connected through the T-shaped clamp 5. In this way, the finished confinement pen is assembled.

[0034] Since all components of the limiting rail are made of QN series stainless steel (specifically QN1701 stainless steel), the assembled finished limiting rail has excellent corrosion resistance without surface hot-dip galvanizing treatment and has the advantage of being not easy to rust. In addition, since there is no need for the hot-dip galvanizing treatment process, the overall processing process of the limiting rail is less, the processing is simple and the cycle is short. At the same time, since the surface of the limiting rail does not require hot-dip galvanizing treatment, there is no need to drill hot-dip galvanizing holes on the surface of the limiting rail, making it not easy to accumulate dirt during the breeding process and easy to clean. In addition, the material of the limiting rail itself has excellent antibacterial properties, so the use of disinfectant water can be effectively reduced, which can not only save costs but also effectively avoid the corrosion problem of the disinfectant water to the limiting rail. In addition, since the overall limiting rail is assembled, the assembly points are connected by corresponding T-shaped clamps, and there is no need to weld between the assembly points, which also effectively simplifies the processing process of the limiting rail and has the advantages of simple processing and short cycle.

[0035] In the present utility model, the front door 2 and the rear door 3 can be respectively connected to the side rail 1 by using existing separable connection methods.
