Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a leveling mechanism for European-style prefabricated substations. Background Technology

[0002] European-style box-type substations, also known as European-style box-type transformers or European-style substations, are a type of box-type substation. They are characterized by their completeness, small size, compact structure, safe and reliable operation, convenient maintenance, and portability.

[0003] As critical outdoor power distribution equipment, European-style prefabricated substations often suffer from uneven foundation settlement, construction errors, and complex terrain, affecting the flatness of their installation foundations and resulting in horizontal deviations after installation. These deviations cause uneven stress on the substation frame, leading to door deformation, seal failure, and additional stress on internal busbar connections and circuit breaker operating mechanisms. Long-term operation can easily result in overheating at connection points, insulation degradation, and shortened equipment lifespan, posing safety hazards.

[0004] Existing leveling devices mostly rely on repeated adjustments using external tools and require multiple measurements and corrections using an independent level, resulting in cumbersome operation, low efficiency, and susceptibility to corrosion of exposed threaded parts. Therefore, the applicant has developed a beneficial design and found a solution to the above problems. The technical solution described below arose from this background. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the traditional European-style prefabricated transformer design and to provide a product that improves operational efficiency and extends service life.

A level is provided within the housing and positioned between adjacent height adjustment mechanisms. Each height adjustment mechanism includes a base and a top column fitted onto the base. A rotatable worm gear is provided inside the base and meshes with the top column. A worm is provided on one side of the base and meshes with the worm gear. O-rings are provided between the worm and the base, and between the base and the top column.

[0007] Preferably, the base has a chamber for accommodating the worm gear, the chamber has a support for supporting the worm gear, and the support has a plurality of rollers arranged along the circumferential direction.

[0008] Preferably, the base has a bearing portion for accommodating the worm gear on one side, the bearing portion is connected to the chamber, ball bearings are provided at both ends of the bearing portion, and a cover is provided at one end of the bearing portion.

The end of the lead screw is provided with a limiting ring and abuts against the bottom of the chamber.

[0012] Preferably, the base and top column are provided with mounting flanges. Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a height adjustment mechanism driven by a worm gear at the bottom of the housing, combined with a level on the housing, to achieve intuitive monitoring and convenient adjustment of the housing's levelness. The worm gear drive has a self-locking characteristic, ensuring that the position is automatically maintained after leveling without the need for an additional locking device.

[0018] Reference example Figures 1 to 5 A leveling mechanism for a European-style prefabricated substation includes a housing 1. The bottom of the housing 1 is provided with multiple height adjustment mechanisms 2. The housing 1 is provided with a level 3 and is arranged between adjacent height adjustment mechanisms 2. The height adjustment mechanism 2 includes a base 21 and a top column 22 sleeved on the base 21. The base 21 is provided with a rotatable worm gear 23 and meshes with the top column 22. A worm 24 is provided on one side of the base 21 and meshes with the worm gear 23. An O-ring seal 4 is provided between the worm 24 and the base 21, and between the base 21 and the top column 22. The level 3 is a bubble level. By setting a height adjustment mechanism 2 at the bottom of the housing 1, driven by a worm gear 23 and a worm 24, and combining it with a level 3 on the housing 1, the levelness of the housing 1 can be intuitively monitored and conveniently adjusted. The worm gear 23 and worm 24 transmission has a self-locking characteristic, ensuring that the position is automatically maintained after leveling without the need for an additional locking device. The fully enclosed structure and sealing design effectively prevent corrosion in outdoor environments, extending the service life of the mechanism. The overall structure significantly improves operating efficiency and equipment reliability while ensuring leveling accuracy. It is worth mentioning that the base 21 is provided with a chamber 211 for accommodating the worm gear 23. The chamber 211 is provided with a support part 212 for supporting the worm gear 23. The support part 212 is provided with several rollers 25 along the circumferential direction. The rollers 25 reduce the frictional resistance and wear of the worm gear 23 when it rotates, making the adjustment process easier and smoother, extending the service life of the transmission structure. At the same time, it also reduces the rotational force when the operator operates the worm 24, achieving the effect of saving effort. It is worth mentioning that a bearing portion 213 for accommodating the worm gear 24 is provided on one side of the base 21. The bearing portion 213 is connected to the chamber 211. Ball bearings 5 ​​are provided at both ends of the bearing portion 213, and a cover 6 is provided at one end of the bearing portion 213. The worm gear 24 is supported by the ball bearings 5, which further optimizes the transmission efficiency, reduces energy loss and operating torque, and further reduces the rotational force required for operation. The integrated design of the bearing portion 213 and the chamber 211 ensures the accuracy of the meshing center distance between the worm gear 24 and the worm wheel 23, and improves the smoothness and accuracy of the transmission. The design of the cover 6 provides a closed operating environment for the worm gear 24, prevents the loss of lubricating grease and the entry of contaminants, and enhances the overall integrity and protection level of the structure. It is worth mentioning that the chamber 211 is equipped with a limiting member 26 to restrict the displacement of the worm wheel 23 axis. The limiting member 26 positions the worm wheel 23 axis to prevent the worm wheel 23 from moving up or down, so that the worm wheel 23 always maintains the best meshing state with the worm 24, maintains the sensitivity and accuracy of adjustment, and also significantly improves the structural rigidity and operational stability of the entire mechanism. It is worth mentioning that the worm gear 24 is pivotally mounted on the inner ring of the ball bearing 5, the O-ring seal 4 is located below the ball bearing 5, the worm gear 24 is equipped with an operating handwheel 27, the ball bearing 5 ensures the coaxiality and stability of the rotation of the worm gear 24, the O-ring seal 4 is placed below the ball bearing 5 to prevent external humid air from penetrating into the chamber 211, effectively blocking the path of contaminants from the outside, and the operating handwheel 27 provides convenience for on-site adjustment, enabling operators to easily and effortlessly complete height adjustments; It is worth mentioning that the top column 22 is provided with a guide part 221 and is sleeved on the outer wall of the base 21. The top column 22 is also provided with a lead screw 222 and engages with the inner hole of the worm gear 23. The end of the lead screw 222 is provided with a limiting ring 223 and abuts against the bottom of the chamber 211. The guide part 221 ensures that the top column 22 remains vertical and without swaying during the lifting process, ensuring the accuracy and safety of the adjustment of the housing 1. The engagement of the lead screw 222 with the inner hole of the worm gear 23 accurately converts the rotational motion into linear motion, while the limiting ring 223 at the end limits the lifting stroke of the top column 22. It is worth mentioning that the base 21 and the top column 22 are equipped with mounting flanges 7.
