Description

Technical Field

[0001] This invention relates to the field of modular prefabricated module technology, specifically a modular prefabricated module for substations and a substation. Background Technology

[0002] For example, Chinese patent CN115506636B discloses a modular prefabricated module and substation for substations. The prefabricated module has one or more layers. Each layer of the prefabricated module is composed of multiple electrical equipment modules and multiple auxiliary function modules divided according to function, which are spliced ​​horizontally. Each electrical equipment module and each auxiliary function module are prefabricated and wired in the factory and are each an independent transportation and installation unit. Each electrical equipment module and each auxiliary function module are installed by top hoisting.

[0003] However, the above solutions have the following shortcomings: Existing prefabricated modules generally adopt the bottom hoisting method. After the module is in place, it needs to be leveled with shims to adapt to the unevenness of the foundation surface. This repetitive operation process of "hoisting-observation-lifting-inserting shims-repositioning" not only relies heavily on the coordination between the crane operator and the ground installation workers, resulting in low installation efficiency, but also in complex terrain environments such as mountains, hills, and permafrost, the top surface of the foundation often has a large inclination or unevenness, making it extremely difficult to find shims of suitable thickness and accurately insert them into the gaps. In addition, in emergency repair or temporary substation scenarios, there are extreme requirements for installation speed, and the traditional shim leveling method is difficult to meet the needs of rapid power restoration. Therefore, we have introduced a modular prefabricated module and substation for substations. Summary of the Invention

[0010] Preferably, the transmission gear has several screw holes at its upper end, and the connecting box has a limiting screw on its outer side, with the lower end of the limiting screw screw screwed into the screw holes.

[0011] In addition, to achieve the above objectives, the present invention also provides a substation, including the aforementioned modular prefabricated substation module.

The outer sides of the first prefabricated modules 1, first side prefabricated modules 5, second side prefabricated modules 2, and corner connecting modules 3 are respectively provided with protrusions and recesses of corresponding shapes. Through the setting of these protrusions and recesses, the first prefabricated modules 1, first side prefabricated modules 5, second side prefabricated modules 2, and corner connecting modules 3 can be spliced ​​together. Then, the protrusions can be limited in the recesses by fasteners such as bolts. At the same time, during use, door openings can be made in the first side prefabricated modules 5 or second side prefabricated modules 2 for the installation of entry doors, allowing operators to enter the modular prefabricated module 100.

[0017] The first prefabricated compartment 1 is equipped with several electrical boxes 8. Through the setting of electrical boxes 8, the electrical components required by the substation can be installed in the electrical boxes 8. The lower end of the modular prefabricated compartment 100 is equipped with a support mechanism, and the lower end of the support mechanism is equipped with several external threaded lifting columns 10. The external threaded lifting columns 10 have threaded grooves on their outer sides. The external threaded lifting columns 10 are slidably connected to the connecting box 4. The inner side of the connecting box 4 is polygonal, and the outer side of the external threaded lifting columns 10 is also polygonal. Through this shape setting, the external threaded lifting columns 10 will not rotate when the internal threaded toothed ring 10 rotates. The connecting box 4 is equipped with a transmission mechanism, which is connected to the external threaded lifting columns 10. The transmission mechanism drives the external threaded lifting columns 10 to move. The connecting box 4 is equipped with an oiling mechanism, which is connected to the external threaded lifting columns 10. The oiling mechanism applies protective oil to the surface of the external threaded lifting columns 10.

[0018] Example 2: Based on Example 1, in order to improve the robustness of the installed modular prefabricated cabin 100, the support mechanism includes several vertical support plates 6 and horizontal support plates 7. Several vertical support plates 6 are installed at the lower end of the modular prefabricated cabin 100, and several horizontal support plates 7 are connected to the vertical support plates 6. The upper end of the external threaded lifting column 10 is installed at the lower end of the horizontal support plate 7 through several first screws 17. Several vertical support plates 6 are installed below the assembled modular prefabricated cabin 100 through screws. Then, several horizontal support plates 7 and several vertical support plates 6 are installed together. The strength of the modular prefabricated cabin 100 is improved by setting several vertical support plates 6 and horizontal support plates 7.

[0019] The transmission mechanism includes an internally threaded gear ring 12, which has an internally threaded groove on its inner side. The internally threaded gear ring 12 is movably connected to the connecting box 4. Slip rings are fixedly connected to the upper and lower ends of the internally threaded gear ring 12, and the internally threaded gear ring 12 is limited by sliding the slip rings in the connecting box 4. An externally threaded lifting column 10 is screwed to the inner side of the internally threaded gear ring 12, and a transmission gear 15 is meshed on the outer side of the internally threaded gear ring 12. The transmission gear 15 is set in the connecting box 4, and a first connecting rod 20 is fixedly connected to the lower end of the transmission gear 15. The lower end of the first connecting rod 20 has a groove, and the upper end of a second connecting rod 18 is inserted into the groove. The lower end of the first connecting rod 20 passes through the connecting box 4 and extends into the external environment.

[0020] A second connecting rod 18 is installed on the inner side of the first connecting rod 20 by a first bolt 21. The second connecting rod 18 is fixedly connected to the output end of the drive motor 11. The drive motor 11 is installed on the upper end of the mounting plate 19 by several second bolts 23. One end of the mounting plate 19 is fixedly connected to the outside of the connecting box 4. The limiting screw 25 is screwed upward so that its lower end is disengaged from the screw hole 24. The drive motor 11 is then installed together with the mounting plate 19 by the second bolts 23. During installation, ensure that the second connecting rod 18 located at the output end of the drive motor 11 is inserted into the first connecting rod 20. After the drive motor 11 is installed, the second connecting rod 18 is fixed together with the first connecting rod 20 by the first bolt 21.

[0021] The coating mechanism includes an annular tube 14, which is fixedly connected to the inner side of the connecting box 4. Several permeation holes are opened on the inner side of the annular tube 14, and a liquid-absorbing ring 16 is also fixedly connected thereto. The liquid-absorbing ring 16 is an elastic cotton ring. When the rust-preventive oil enters the annular tube 14, the rust-preventive oil in the annular tube 14 can enter the liquid-absorbing ring 16 through the permeation holes and be absorbed by the liquid-absorbing ring 16. A liquid guide tube 13 is fixedly connected to the outer side of the annular tube 14. The end of the liquid guide tube 13 away from the annular tube 14 extends into the external environment and is fixedly connected to a valve 22. The upper end of the valve 22 is fixedly connected to the lower end of the liquid storage tank 9. The liquid storage tank 9 is fixedly connected to the outer side of the connecting box 4. Several screw holes 24 are opened on the upper end of the transmission gear 15. A limit screw 25 is provided on the outer side of the connecting box 4. The lower end of the limit screw 25 is screwed into the screw holes 24.

[0022] In addition, to achieve the above objectives, the present invention also provides a substation including the aforementioned modular prefabricated substation module.

[0023] Working principle: During use, according to the required size of the modular prefabricated cabin 100, several first prefabricated cabins 1 are spliced ​​together and fixed. Then, several first side prefabricated cabins 5, second side prefabricated cabins 2, and corner connecting cabins 3 are spliced ​​together with the first prefabricated cabins 1 and fixed with bolts to form a complete modular prefabricated cabin 100. First, several vertical support plates 6 are installed under the assembled modular prefabricated cabin 100 by screws. Then, several horizontal support plates 7 are installed together with several vertical support plates 6. The strength of the modular prefabricated cabin 100 is improved by setting several vertical support plates 6 and horizontal support plates 6. According to the size of the modular prefabricated cabin 100, a corresponding number of external threaded lifting columns 10 are installed at the lower end of the horizontal support plates 6 by first screws 17. After all installations are completed, the lower end of the connecting box 4 is installed with the ground. When the modular prefabricated cabin 100 tilts to one side, the extension length at that position is adjusted so that the tilted part of the modular prefabricated cabin 100 returns to a horizontal state. Specifically, the limit screw 25 is turned upward so that its lower end is disengaged from the screw hole 24. The drive motor 11 is installed together with the mounting plate 19 by the second bolt 23. During installation, ensure that the second connecting rod 18 located at the output end of the drive motor 11 is inserted into the first connecting rod 20. After the drive motor 11 is installed, the second connecting rod 18 is fixed together with the first connecting rod 20 by the first bolt 21. The valve 22 is opened so that the rust-preventive oil in the storage tank 9 enters the liquid guide pipe 13. The rust-preventive oil then enters the annular pipe 14 through the liquid guide pipe 13. The rust-preventive oil enters the liquid suction ring 16 through the permeation hole on the inner side of the annular pipe 14. Turn on the drive motor 11 to drive the second connecting rod 18 to rotate. At this time, the first connecting rod 20 drives the drive gear 15 to rotate. Since the drive gear 15 meshes with the internal threaded toothed ring 12, the internal threaded toothed ring 12 will rotate when the drive gear 15 rotates. The internal threaded toothed ring 12 is screwed with an external threaded lifting column 10. Therefore, when the internal threaded toothed ring 12 rotates, the external threaded lifting column 10 will move upward along the connecting box 4. The upward movement of the external threaded lifting column 10 lifts the modular prefabricated cabin 100. By adjusting the extension length of several external threaded lifting columns 10, the modular prefabricated cabin 100 is leveled. After the external threaded lifting column 10 is extended, the drive motor 11 self-locks so that the external threaded lifting column 10 will not move. Rotate the limit screw 25 downward so that its lower end is screwed into the screw hole 24 to complete the limit of the drive gear 15. After the adjustment is completed, the drive motor 11 can be removed. During the movement of the external thread lifting column 10, the rust-preventive oil adsorbed in the liquid suction ring 16 will be applied to the surface of the external thread lifting column 10. The application of the rust-preventive oil will improve the lubrication between the external thread lifting column 10 and the internal thread toothed ring 12. After the adjustment is completed, the valve 22 can be closed.
