Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a box-type transformer structure that can adjust its level. Background Technology

[0002] European-style prefabricated substations (prefabricated substations) are widely used in power systems, and their installation stability directly affects the safety of equipment operation and the convenience of maintenance. However, during the installation of European-style prefabricated substations, uneven foundations often cause the substation to tilt, resulting in the substation doors being unable to open or close properly, a phenomenon known in the industry as "door corner falling off".

[0003] Currently, the main adjustment methods for "door panel corner falling off" in the industry are as follows: (1) Manual crowbar adjustment: Relying on multiple people to operate the crowbar to lift the lower end of the transformer box and put some hard materials in the gap to adjust the transformer box to a horizontal position, so that the door panel can be opened and closed normally. However, this method has low work efficiency and poor safety. Moreover, because the transformer box is very heavy, it is easy to cause personnel injury or equipment slippage risk; (2) Use a hydraulic truck or lifting equipment to lift the lower end of the transformer box and then put some hard materials in the gap to adjust the transformer box to a horizontal position. However, hydraulic trucks require a large operating space, but since transformer substations are often installed on narrow, elevable platforms (such as densely distributed substations in the "warehouse adjustment" process of power supply bureaus), or the height of the platform exceeds the working range of the hydraulic truck, the equipment cannot be intervened, making it unsuitable to use hydraulic trucks; (3) Using a crane or forklift with a lifting rope to lift the lower end of the transformer substation, and then padding some hard materials on the foundation in the gap, however, in this scheme, during warehouse adjustment, the project of each transformer substation will consider the problem of hoisting and positioning, and the crane will leave after hoisting the transformer substation to the platform and positioning it, which is costly and delays the construction period. Therefore, these adjustment methods all have significant limitations in actual construction. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide an adjustable-level transformer substation structure. This structure allows for convenient and quick adjustment of the substation body to a horizontal position, improving work efficiency and reducing costs. The technical solution adopted is as follows:

[0005] A levelable transformer substation structure includes a main body with four corners at the bottom. The structure further includes a base and four height adjustment mechanisms. The base is installed at the bottom of the main body, and the front, rear, left, and right sides of the base are provided with outward-facing channel steel. Each channel steel has multiple through holes on its bottom plate. The four height adjustment mechanisms are respectively located on the lower side of the corresponding corners of the main body. Each height adjustment mechanism is used to adjust the height of the corresponding corner. Each height adjustment mechanism includes a hydraulic jack installed inside the corresponding channel steel. The pressure block of the hydraulic jack faces downward, and multiple vertically oriented top columns are installed on the pressure block. The lower end of each top column is located in a corresponding through hole. A compression spring is sleeved on each top column, and the upper and lower ends of the compression spring are connected or in close contact with the pressure block of the hydraulic jack and the bottom plate of the corresponding channel steel, respectively.

[0006] During the installation of the aforementioned transformer substation structure, if the main body of the transformer substation tilts due to uneven foundation, the position of a certain corner of the main body that is lower can be adjusted using the corresponding height adjustment mechanism to raise that corner of the main body of the transformer substation and adjust it to a horizontal state. By pressing the handle of the hydraulic jack, the pressure block is pressed down, which drives each jack column to pass through the corresponding through hole at the bottom of the channel steel to press against the ground. Using the reaction force of the ground, the lower corner of the main body of the transformer substation is slightly raised to adjust it to a horizontal state. After placing some hard material on the ground in the gap, the hydraulic jack is depressurized, and its pressure block is raised upward under the action of the compression spring, so that each jack column does not protrude beyond the bottom plate of the channel steel and interfere with the ground.

[0007] As a specific embodiment of this utility model, the transformer substation body includes a box and a roof. The box is mounted on the base and located on the upper side of the base. The box has multiple door openings and multiple doors for closing each door opening. The roof is installed on the top of the box. The box typically houses capacitor banks, incoming line cabinets, and feeder cabinets, etc.

[0008] As a preferred embodiment of this invention, the hydraulic jack has four top columns arranged in a rectangular array mounted on its pressure block. This allows the hydraulic jack to apply a more uniform force to the ground.

[0009] As a preferred embodiment of this utility model, the hydraulic jack has a horizontally rotatable handle. When the hydraulic jack is needed to adjust the height of a corresponding corner of the transformer substation body, the handle can be rotated horizontally from the inside to the outside of the channel steel for easy pressing. When the hydraulic jack is not in use, the handle can be rotated horizontally from the outside to the inside of the channel steel, thus making good use of the O-shaped space of the channel steel to store the hydraulic jack. The design is reasonable and ingenious.

[0010] As a further preferred embodiment of this utility model, an extension sleeve is provided on the outer side of the handle, and the extension sleeve can slide relative to the handle along the length direction of the handle. When adjustment is required using a hydraulic jack, the handle of the hydraulic jack is rotated to the outside of the channel steel, and the extension sleeve is pulled out to increase the actual total length of both, thereby lengthening the lever arm of the handle, making operation more convenient and labor-saving. When adjustment is not required using the hydraulic jack, the extension sleeve can be retracted to reduce the actual total length of both, making it easier to store.

[0011] As a preferred embodiment of this utility model, a sealing plate is detachably installed at the groove opening of the channel steel. When the hydraulic jack is not needed for adjustment, the sealing plate can be used to cover the groove opening of the corresponding channel steel to prevent the handle from coming out of the groove opening.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This type of prefabricated substation structure uses a base mounted on the bottom of the substation body, with multiple height adjustment mechanisms installed on the base to adjust the height of each corner of the substation body. When the substation body tilts due to uneven foundation, the height of the corresponding corner can be adjusted using the appropriate height adjustment mechanism. The lowered corner of the substation body can be slightly raised, and a hard material can be placed in the gap under the raised part of the base. This allows the substation body to be easily and effortlessly adjusted to a level position without occupying a large operating space, thus improving work efficiency and reducing costs.

[0019] like Figures 1-5As shown, this adjustable-level transformer substation structure includes a transformer substation body 1, a base 2, and multiple height adjustment mechanisms 3. The transformer substation body 1 includes a box 11 and a roof 12. The box 11 is mounted on the base 2 and is located on the upper side of the base 2. The box 11 houses a capacitor cabinet 111, an incoming line cabinet 112, and a feeder cabinet 113. The box 11 has multiple door openings 1101 and multiple doors 1102 for closing each door opening 1101. The roof 12 is mounted on the top of the box 11. The base 2 is mounted on the bottom of the box 11. Each height adjustment mechanism 3 is mounted on the base 2 and is located on the lower side of the corresponding corner 1103 at the bottom of the box 11. The height adjustment mechanism 3 is used to adjust the height position of the corresponding corner 1103 of the box 11.

[0020] In this embodiment, the bottom of the box 11 has four corners 1103; correspondingly, there are four height adjustment mechanisms 3, which are respectively disposed on the lower side of the corresponding four corners 1103 of the box 11. The height adjustment mechanisms 3 are used to adjust the height position of the corresponding corners 1103 of the box 11. The four height adjustment mechanisms 3 can be used to adjust the height position of the four corners 1103 at the bottom of the box 11, making it easier to adjust the box 11 to a horizontal state.

[0021] In this embodiment, the base 2 has channel steel 21 with outward-facing slots 210 on its front, rear, left, and right sides. Each channel steel 21 has multiple through holes 211 on its bottom plate. The height adjustment mechanism 3 includes a hydraulic jack 31, which is installed inside the corresponding channel steel 21. The pressure block 311 of the hydraulic jack 31 is set downward. Four top posts 32 arranged vertically and forming a rectangular array are installed on the pressure block 311 of the hydraulic jack 31. The lower end of each top post 32 is located in the corresponding through hole 211. A compression spring 33 is sleeved on each top post 32. The upper and lower ends of the compression spring 33 are in close contact with the pressure block 311 of the hydraulic jack 31 and the bottom plate of the corresponding channel steel 21, respectively. The hydraulic jack 31 has a horizontally rotatable handle 312. An extension sleeve 313 is sleeved on the outside of the handle 312. The extension sleeve 313 can slide relative to the handle 312 along the length direction of the handle 312.

[0022] The following is a brief description of how to use this type of box-type transformer structure:

[0023] When the transformer substation body 1 tilts due to uneven foundation, the handle 312 of the hydraulic jack 31 of the corresponding height adjustment mechanism 3 can be rotated horizontally from the inside to the outside of the channel steel 21, depending on the location of the lower corner 1103 of the substation body 11. This allows the extension sleeve 313 to be pulled outward relative to the handle 312, increasing the total length of both. Then, the extension sleeve 313 presses down on the handle 312 of the hydraulic jack 31, causing it to press down on the pressure block 311. This drives the jacks 32 to pass through the corresponding through holes 211 at the bottom of the channel steel 21 to press against the ground. Using the ground's reaction force, the lower corner 1103 of the substation body 11 is slightly raised to a horizontal position. At this corner 1103, the lower corner is aligned with the ground. After placing some hard material on the ground to fill the gap formed by the surface, the hydraulic jack 31 is depressurized. Its pressure block 311 is lifted upward under the action of the compression spring 33, so that the top columns 32 do not protrude from the bottom plate of the channel steel 21 and interfere with the ground. After using the hydraulic jack 31, the extension sleeve 313 is retracted to reduce the actual total length of the two. Then, the handle 312 of the hydraulic jack 31 is rotated horizontally from the outside of the channel steel 21 to the inside of the channel steel 21. This makes good use of the O-shaped space of the channel steel 21 to store the hydraulic jack 31. Finally, the slot 210 of the channel steel 21 is covered by the sealing plate to prevent the handle 312 from leaking out of the slot 210 of the channel steel 21, making it safer to use.

[0024] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles of this utility model patent are included within the protection scope of this utility model patent.
