Description

Technical Field

[0001] This invention belongs to the field of substation technology, specifically relating to an intelligent leveling foundation structure for a prefabricated substation. Background Technology

[0002] Prefabricated substations, with their advantages of compact size and flexible layout, have been widely used in urban power grid upgrades, industrial construction, and other scenarios. As the intelligence and automation levels of power systems continue to improve, the functions of prefabricated substations are becoming increasingly diverse, and the integrated electrical equipment is becoming more sophisticated. This places higher demands on the installation stability and adaptability of prefabricated substations during use.

[0003] Traditional prefabricated substations typically use concrete foundations, which cannot be adjusted after construction. However, in actual use, the installation environment of prefabricated substations is complex and diverse. Some installation sites have significant terrain undulations, uneven foundation bearing capacity, or foundation settlement during use, all of which may cause the prefabricated substation to tilt, thereby affecting the normal operation of internal electrical equipment and even causing safety hazards. Summary of the Invention

[0004] This invention provides an intelligent leveling foundation structure for prefabricated substations, aiming to solve the technical problem that existing prefabricated substations are prone to tilting after installation, affecting the normal operation of internal electrical equipment and even causing safety hazards.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an intelligent leveling foundation structure for a prefabricated substation, comprising: Mounting platform, used for installing prefabricated substations; A base is located at the bottom of the mounting platform. The base contains a first adjusting shaft and a second adjusting shaft spaced vertically apart. Both the first and second adjusting shafts are rotatably fitted onto the base. The axes of the first and second adjusting shafts are perpendicularly distributed. A first adjusting rod is fixedly connected to the first adjusting shaft, perpendicular to the axis of the first adjusting shaft. First adjusting brackets are hinged to both ends of the first adjusting rod. A second adjusting rod is fixedly connected to the second adjusting shaft, perpendicular to the axis of the second adjusting shaft. Second adjusting brackets are hinged to both ends of the second adjusting rod. Both the first and second adjusting brackets are slidably connected to the base in the vertical direction. A first gear is provided on the first adjusting shaft, and a worm gear is provided on the second adjusting shaft. A support assembly is disposed within the base and supported at the center bottom of the mounting platform; the support assembly has a lifting part. An adjusting motor is fixedly connected to the lifting part. The output shaft of the adjusting motor is provided with a second gear for meshing with the first gear and a worm for meshing with the worm wheel. An inclination sensor is mounted on the mounting platform; The controller is configured to activate the lifting unit to drive the adjustment motor to lift and lower based on the reading of the tilt sensor, thereby switching the transmission connection between the adjustment motor and one of the first and second adjustment shafts, and driving the first or second adjustment shaft to rotate by a preset angle.

[0006] In one possible implementation, the support component includes: An external support column is located within the base and supports the bottom of the mounting platform; The inner support column is located inside the outer support column and slides in the vertical direction to fit the outer support column. A lifting mechanism is located at the bottom of the support assembly and is used to drive the inner support column to rise and adjust. Both the outer support and the inner support are provided with a first through slot for the first adjusting rod to pass through and a second through slot for the second adjusting rod to pass through.

[0007] In one possible implementation, the lifting mechanism includes: The first hydraulic cylinder is fixed at the bottom inside the outer support column; A connecting frame is fixed to the hydraulic rod of the first hydraulic cylinder. The connecting frame includes a plurality of connecting rods arranged radially, and the end of each connecting rod opposite to the hydraulic rod is fixed to the side wall of the inner support column.

[0008] In one possible implementation, the end of the connecting rod opposite to the hydraulic rod extends outward from the outer side of the inner support to form a guide portion; The inner sidewall of the outer support column is provided with a guide groove that mates with the guide portion, and the guide groove extends in the vertical direction.

[0009] In one possible implementation, the top of the outer support column is provided with an upward-facing receiving groove, the receiving groove being an annular groove, and the support assembly further includes: The cover plate is fixed to the center bottom of the mounting platform; The shock-absorbing spring is fixed to the cover plate at its top end and extends into the receiving groove at its bottom end.

[0010] In one possible implementation, the base has a first hinge seat on each of its two opposite sidewalls, and the two first hinge seats are respectively rotatably engaged with the two ends of the first adjusting shaft; The base is provided with two other opposite sidewalls, each with a second hinge seat. The two second hinge seats are rotatably fitted to the two ends of the second adjusting shaft.

[0011] In one possible implementation, both the first hinge base and the second hinge base include: A fixing sleeve is fixed to the side wall of the base and has an opening facing the support assembly; A rolling bearing is disposed within the fixed sleeve; An abutment spring is provided inside the fixed sleeve; Wherein, the rolling bearing in the first hinge seat is sleeved on the outer periphery of the first adjusting shaft, and the abutting spring abuts against the shaft end of the first adjusting shaft; the rolling bearing in the second hinge seat is sleeved on the outer periphery of the second adjusting shaft, and the abutting spring abuts against the shaft end of the second adjusting shaft.

[0012] In one possible implementation, both the first adjusting frame and the second adjusting frame include: Hinge shaft; Multiple sliding rods are rotatably connected to the hinge shaft, the multiple sliding rods are spaced apart along the axial direction of the hinge shaft, the sliding rods extend in the vertical direction, and the sliding rods slide in engagement with the side wall of the base; A top rod is located above the base and abuts against the bottom surface of the mounting platform. The top rod is fixedly connected to the top ends of the plurality of sliding rods.

[0013] In one possible implementation, the top of the push rod is provided with a rubber pad.

[0014] In one possible implementation, the rubber pad covers the top surface of the top rod; or, multiple rubber pads are evenly distributed along the length of the top rod.

[0015] Compared with the prior art, the solution shown in this application embodiment, by setting a first adjustment shaft and a second adjustment shaft that are perpendicular to each other in the base, and in conjunction with an inclination sensor and a controller, can respectively correct the tilt state of the mounting platform in the front-to-back direction and the left-to-right direction, so as to achieve multi-directional horizontal adjustment and ensure that the box-type substation is always in a stable posture.

[0016] The rotation of the first and second adjusting shafts is controlled by the same adjusting motor, which moves up and down with the lifting unit. The transmission connection with the first or second adjusting shaft can be switched. Compared with setting two motors, this structure is more compact, has a lower failure rate, and is simpler to control.

[0017] The support components support the center of the mounting platform, and the first and second adjustment frames around it lift it up. The force is evenly distributed and the adjustment process is smooth, which can effectively avoid uneven loading, jamming or shaking during the leveling process, and improve the overall stability and safety of the foundation structure.

[0018] The tilt sensor can collect the tilt information of the mounting platform in real time and transmit it to the controller for judgment and calculation. It has a high degree of automation and can adjust itself under specific conditions to adapt to complex working conditions such as foundation settlement and uneven terrain, ensuring the long-term reliable operation of internal electrical equipment.

Detailed Implementation

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0022] Please refer to the following: Figures 1 to 3 The present invention will now describe the intelligent leveling foundation structure for the prefabricated substation 20. The intelligent leveling foundation structure for the prefabricated substation 20 includes a mounting platform 10, a base 30, a support assembly 40, an adjusting motor 50, a tilt sensor 60, and a controller.

[0023] Mounting platform 10 is used to install the prefabricated substation 20.

[0024] The base 30 is located at the bottom of the mounting platform 10. The base 30 is provided with a first adjusting shaft 31 and a second adjusting shaft 34 spaced vertically. The first adjusting shaft 31 and the second adjusting shaft 34 are rotatably fitted to the base 30. The first adjusting shaft 31 and the second adjusting shaft 34 are vertically distributed along their axes.

[0025] A first adjusting rod 32 is fixedly connected to the first adjusting shaft 31. The first adjusting rod 32 is perpendicular to the axial direction of the first adjusting shaft 31, and a first adjusting frame 33 is hinged to both ends of the first adjusting rod 32. A second adjusting rod 35 is fixedly connected to the second adjusting shaft 34. The second adjusting rod 35 is perpendicular to the axial direction of the second adjusting shaft 34, and a second adjusting frame 36 is hinged to both ends of the second adjusting rod 35.

[0026] The first adjusting frame 33 and the second adjusting frame 36 are both slidably connected to the base 30 in the vertical direction. The first adjusting shaft 31 is provided with a first gear 311, and the second adjusting shaft 34 is provided with a worm gear 341.

[0027] The support component 40 is located inside the base 30 and is supported at the center bottom of the mounting platform 10. The support component 40 has a lifting part.

[0028] The adjusting motor 50 is fixed to the lifting part. The output shaft of the adjusting motor 50 is provided with a second gear 51 for meshing with the first gear 311, and a worm 52 for meshing with the worm gear 341.

[0029] The tilt sensor 60 is mounted on the mounting platform 10.

[0030] The controller is configured to activate the lifting unit to drive the adjusting motor 50 to lift and lower based on the reading of the tilt sensor 60, thereby switching the transmission connection between the adjusting motor 50 and one of the first adjusting shaft 31 and the second adjusting shaft 34, and driving the first adjusting shaft 31 or the second adjusting shaft 34 to rotate by a preset angle.

[0031] It should be noted that the base 30 and mounting platform 10 are mostly made of concrete. During the lifting and lowering process, in order to reduce friction, a stainless steel inner lining layer needs to be installed between the sliding fit structures to improve the smoothness of the sliding process. Similarly, bearings can be installed between the rolling fit structures.

[0032] In the initial position, the adjusting motor 50 is positioned between the first adjusting shaft 31 and the second adjusting shaft 34, with the first gear 311 and the second gear 51 disengaged, and the worm gear 341 disengaged from the worm 52. When the adjusting motor 50 moves upward with the lifting unit, the second gear 51 on the output shaft of the adjusting motor 50 meshes with the first gear 311 on the first adjusting shaft 31, and the worm gear 341 disengages from the worm 52, thereby activating the adjusting motor 50 and driving the first adjusting shaft 31 to rotate. When the adjusting motor 50 moves downward with the lifting unit, the worm gear 341 on the output shaft of the adjusting motor 50 meshes with the worm 52, and the first gear 311 and the second gear 51 disengage, activating the adjusting motor 50 and driving the second adjusting shaft 34 to rotate.

[0033] The first adjusting shaft 31 is parallel to the left-right direction, and the first adjusting rod 32 is parallel to the front-back direction, meaning one of the first adjusting brackets 33 is located on the front side and the other on the rear side. The second adjusting shaft 34 is parallel to the front-back direction, and the second adjusting rod 35 is parallel to the left-right direction, meaning one of the second adjusting brackets 36 is located on the left side and the other on the right side. The reverse is also true.

[0034] In this embodiment, the tilt sensor 60 is mounted on the mounting platform 10, ensuring alignment with the platform in both length and width directions and proper marking. The readings of the tilt sensor 60 are transmitted to the controller. The X-axis of the tilt sensor 60 represents the front-to-back direction, and the Y-axis represents the left-to-right direction. When the tilt sensor 60 displays tilt angle data X > 0, it indicates that the rear side is higher than the front side; when the tilt angle data X < 0, it indicates that the front side is higher than the rear side; when the tilt angle data Y > 0, it indicates that the left side is higher than the right side; when the tilt angle data Y < 0, it indicates that the right side is higher than the left side.

[0035] The tilt angle data from the tilt sensor 60 can be used to determine the angle that the mounting platform 10 needs to be adjusted. The controller converts the readings from the tilt sensor 60 and calculates the number of rotations required to adjust the current tilt angle according to the transmission ratio of the output shaft of the adjusting motor 50, and determines whether the adjusting motor 50 should rotate forward or backward.

[0036] During actual construction, the base 30 needs to be buried underground. After installation, when the tilt sensor 60 detects the tilt angle, if the tilt angle is within the preset range (e.g., 0 to 10°), the controller directly starts the lifting unit and the adjusting motor 50 to drive the mounting platform 10 to rotate the corresponding angle. When the tilt angle exceeds the preset range, it will not start directly. Instead, an alarm will be sent to the operators, who will then loosen the soil around the base 30 on site before starting the adjusting motor 50 for adjustment.

[0037] Optionally, the controller can be a PLC control system suitable for industrial sites.

[0038] The intelligent leveling foundation structure of the prefabricated substation 20 provided in this embodiment, compared with the prior art, by setting a first adjustment shaft 31 and a second adjustment shaft 34 that are perpendicular to each other in the base 30, and in conjunction with the tilt sensor 60 and the controller, can respectively correct the tilt state of the mounting platform 10 in the front-back direction and the left-right direction, realize multi-directional horizontal adjustment, and ensure that the prefabricated substation 20 is always in a stable posture.

[0039] The rotation of the first adjusting shaft 31 and the second adjusting shaft 34 is controlled by the same adjusting motor 50. The adjusting motor 50 moves up and down with the lifting part and can switch the transmission connection with the first adjusting shaft 31 or the second adjusting shaft 34. Compared with setting two motors, this structure is more compact, has a lower failure rate, and is simpler to control.

[0040] The support component 40 supports the center of the mounting platform 10, and the first adjustment frame 33 and the second adjustment frame 36 around it lift it up. The force is even and the adjustment process is stable, which can effectively avoid uneven loading, jamming or shaking during the leveling process, and improve the overall stability and safety of the foundation structure.

[0041] The tilt sensor 60 can collect the tilt information of the mounting platform 10 in real time and transmit it to the controller for judgment and calculation. It has a high degree of automation and can adjust itself under specific conditions to adapt to complex working conditions such as foundation settlement and uneven terrain, ensuring the long-term reliable operation of internal electrical equipment.

[0042] In some embodiments, a specific implementation of the support component 40 described above may employ, as follows: Figures 1 to 2 The structure is shown. The support assembly 40 includes an outer support column 41, an inner support column 42, and a lifting mechanism 43.

[0043] The outer support column 41 is located inside the base 30 and is supported on the bottom of the mounting platform 10.

[0044] The inner support 42 is located inside the outer support 41 and slides in the vertical direction to engage with the outer support 41.

[0045] The lifting mechanism 43 is located at the bottom of the support assembly 40 and is used to drive the inner support column 42 to lift and adjust.

[0046] The outer support 41 and the inner support 42 are each provided with a first through slot for the first adjusting rod 32 to pass through and a second through slot for the second adjusting rod 35 to pass through.

[0047] It is easy to imagine that during the up-and-down movement of the inner support column 42 within the outer support column 41, it will never protrude from the top surface of the outer support column 41, and therefore will not interfere with the angle adjustment process of the mounting platform 10.

[0048] In this embodiment, since the first adjusting rod 32 needs to rotate with the first adjusting shaft 31, the first through groove is a strip-shaped groove extending in the vertical direction; similarly, since the second adjusting rod 35 needs to rotate with the second adjusting shaft 34, the second through groove is also a strip-shaped groove extending in the vertical direction. The two first through grooves are located on the left and right sides of the support assembly 40, and the two second through grooves are located on the front and rear sides of the support assembly 40. This structure can prevent collisions between the first adjusting rod 32 and the second adjusting rod 35 during rotation, ensuring smooth leveling operation.

[0049] The outer support column 41 and the inner support column 42 form a nested telescopic structure, which not only ensures stable support for the center of the mounting platform 10, but also allows for precise control of the lifting of the inner support column 42 through the lifting mechanism 43, thereby enabling the adjustment motor 50 to switch between the first adjustment shaft 31 and the second adjustment shaft 34 without interference between the support and adjustment processes.

[0050] Specifically, the adjusting motor 50 is fixed inside the inner support column 42, and the inner support column 42 is provided with a mounting bracket for fixing the housing of the adjusting motor 50. Since the inner support column 42 has a first through groove on the left and right sides and a second through groove on the front and rear sides, the mounting bracket can be fixed on the side wall between the adjacent first and second through grooves of the inner support column 42, so that the housing of the adjusting motor 50 is connected to the mounting bracket.

[0051] The regulating motor 50 can be a dual-head motor, with output shafts on both sides of the dual-head motor. One output shaft is used to coaxially mount the second gear 51, and the other output shaft is used to mount the worm gear 52.

[0052] To prevent the output shaft of the adjusting motor 50 from being suspended, a support rod can be installed on the mounting bracket. The top of the support rod is equipped with a bearing, and the suspended end of the output shaft of the adjusting motor 50 cooperates with the bearing to ensure the stability of its rotation process.

[0053] In some embodiments, a specific implementation of the above-described lifting structure may employ, as follows: Figures 1 to 2 The structure shown is as follows. The lifting mechanism 43 includes a first hydraulic cylinder 431 and a connecting frame 432. The first hydraulic cylinder 431 is fixed to the bottom inside the outer support column 41. The connecting frame 432 is fixed to the hydraulic rod of the first hydraulic cylinder 431. The connecting frame 432 includes a plurality of connecting rods arranged radially. The end of each connecting rod away from the hydraulic rod is fixed to the side wall of the inner support column 42.

[0054] The first hydraulic cylinder 431 is installed inside the base 30. Since the base 30 needs to be buried underground, a high-pressure hydraulic oil pipe can be pre-buried before construction, and the first hydraulic cylinder 431 can be connected to the hydraulic oil pipe. During the pre-buried process, an anti-corrosion protective pipe needs to be sleeved on the outside of the hydraulic oil pipe, and a quick-sealing connector should be used at the interface. A solenoid valve (such as a two-position four-way valve) should also be installed on the hydraulic oil pipe. To facilitate the control of the first hydraulic cylinder 431, the solenoid valve can also be connected to a controller, and the hydraulic cylinder can be raised, lowered, and self-locked by the controller.

[0055] In this embodiment, the first hydraulic cylinder 431 is used as the power source. It has a large output thrust and precise stroke control, making it suitable for lifting and adjusting heavy-duty equipment such as the box-type substation 20. The first hydraulic cylinder 431 is installed at the bottom inside the outer support 41, which can locate its installation position, ensure that the position is centered and the force is even, and make the lifting process more stable and improve reliability.

[0056] The connecting frame 432 employs multiple connecting rods arranged radially to distribute thrust from the hydraulic rods outwards, acting synchronously at multiple points on the sidewalls of the inner support column 42. This multi-point force-bearing structure makes the lifting and lowering process of the inner support column 42 smoother and ensures that it does not tilt during vertical movement, guaranteeing accurate engagement between the adjusting motor 50 and the first gear 311 or worm gear 341 during movement.

[0057] When adjusting the initial position of the motor 50, the interval between the first gear 311 and the second gear 51 is x, and the interval between the worm gear 341 and the worm 52 is y. At this time, x=y≠0. When the first hydraulic cylinder 431 is started, the hydraulic rod extends by a length of y. At this time, the motor 50 is connected to the first adjusting shaft 31. When it is necessary to switch to the second adjusting shaft 34, the hydraulic rod of the first hydraulic cylinder 431 is moved down by 2x.

[0058] It should be noted that when the adjusting motor 50 is in its initial state, moving it directly upwards will engage the first gear 311 and the second gear 51, and moving it directly downwards will engage the worm gear 341 and the worm 52. If the adjusting motor 50 rotates upwards a certain number of times and then moves downwards directly, the worm gear 341 and the worm 52 may not engage. Therefore, after the adjusting motor 50 drives one adjusting shaft to rotate a certain angle, before switching to another state, it needs to be reversed by the same number of turns to reset it before connecting it to the other adjusting shaft. This ensures that after moving a preset distance, it can engage with the structure (gear or worm gear 341) on the other adjusting shaft.

[0059] In some embodiments, an improved implementation of the connecting frame 432 may employ, as follows: Figures 1 to 2The structure shown is as follows. The end of the connecting rod away from the hydraulic rod extends out of the outer side of the inner support 42 to form a guide part; the inner side wall of the outer support 41 is provided with a guide groove 411 that cooperates with the guide part, and the guide groove 411 extends in the vertical direction.

[0060] The guide portion moves along the guide groove 411 on the outer support column 41 with the inner support column 42, limiting the direction of movement of the inner support column 42, preventing tilting during movement, and improving the smoothness of the lifting process of the inner support column 42. The radial and lateral forces during the lifting process of the inner support column 42 can be borne by the guide portion and the guide groove 411, reducing the transmission to the first hydraulic cylinder 431, preventing the first hydraulic cylinder 431 from bending, and extending the service life of the first hydraulic cylinder 431.

[0061] Each connecting rod extends out of the inner support column 42 to form a guide part. Multiple connecting rods correspond to multiple guide parts, and multiple guide parts slide in the guide groove 411 to ensure the accuracy of the engagement between the second gear 51 on the adjusting motor 50 and the first gear 311, worm 52 and worm wheel 341.

[0062] In some embodiments, an improved implementation of the support component 40 described above may employ, as follows: Figures 1 to 2 The structure shown is as follows. The top of the outer support column 41 is provided with an upward-facing receiving groove 412, which is an annular groove. The support assembly 40 also includes a cover plate 44 and a shock-absorbing spring 45.

[0063] The cover plate 44 is fixed to the center bottom of the mounting platform 10; the top end of the shock-absorbing spring 45 is fixed to the cover plate 44, and the bottom end extends into the receiving groove 412.

[0064] Optionally, the cover plate 44 and the mounting platform 10 can be connected by countersunk bolts: countersunk bolt holes are made on the cover plate 44, and steel nuts are pre-embedded at the corresponding positions on the bottom of the mounting platform 10. The cover plate 44 is evenly fastened to the bottom surface of the mounting platform 10 in the circumferential direction by multiple countersunk bolts, with the bolt heads sinking into the countersunk holes.

[0065] The bottom of the cover plate 44 can be integrally formed or welded with a circular limiting boss. The top of the shock-absorbing spring 45 is sleeved on the limiting boss. The diameter of the boss is slightly smaller than the inner diameter of the shock-absorbing spring 45 to achieve radial limiting. The top of the shock-absorbing spring 45 is welded and fixed to the cover plate 44 or pressed by a spring pressure seat.

[0066] In this embodiment, the shock-absorbing spring 45 is located between the mounting platform 10 and the outer support column 41. It can absorb the vibration of the equipment during operation and prevent damage to the mounting platform 10, tilt sensor 60, and internal electrical components due to vibration. The annular receiving groove 412 can be used for positioning and installing the shock-absorbing spring 45, preventing the shock-absorbing spring 45 from coming out and ensuring that the shock-absorbing spring 45 is always in the center of the mounting platform 10, with uniform force and strong stability. During the leveling process, the mounting platform 10 may tilt slightly, and the shock-absorbing spring 45 can adapt to the posture change of the mounting platform 10 without hindering the leveling process.

[0067] In some embodiments, a specific installation method for the first adjusting shaft 31 and the second adjusting shaft 34 described above can be as follows: Figures 1 to 3 The structure shown is as follows. Each of the two opposite sidewalls of the base 30 is provided with a first hinge seat 37, and the two first hinge seats 37 are respectively rotatably fitted to the two ends of the first adjusting shaft 31; The base 30 is provided with two other opposite side walls, each with a second hinge seat 38. The two second hinge seats 38 are rotatably fitted to the two ends of the second adjusting shaft 34.

[0068] It should be noted that the first hinge seat 37 and the second hinge seat 38 are both fixed to the inner side wall of the base 30. The two ends of the first adjusting shaft 31 are respectively rotatably engaged with the two first hinge seats 37, and the two ends of the second adjusting shaft 34 are respectively rotatably engaged with the two second hinge seats 38.

[0069] Specifically, during the pouring of the base 30, a steel mounting plate can be pre-embedded, with the position of the mounting plate corresponding to the position of the hinge seat; after the pouring is completed, the hinge seat is welded to the pre-embedded mounting plate to form an integrated structure.

[0070] The first adjusting shaft 31 is supported at both ends by the first hinge seat 37, and the second adjusting shaft 34 is supported at both ends by the second hinge seat 38, resulting in uniform force distribution and no cantilever. During rotation, it is less prone to offset and radial runout, ensuring the accuracy of the adjusting rod and adjusting frame's movement. The hinge seats are installed on opposite side walls of the base 30, forming a support structure at both ends of each adjusting shaft, significantly improving the bending stiffness of the adjusting shaft. This allows it to withstand the heavy lifting force of the prefabricated substation 20, preventing deformation during adjustment and extending its service life.

[0071] In some embodiments, a specific implementation of the above-described hinge seat may employ, as follows: Figures 1 to 3 The structure is shown. Both the first hinge base 37 and the second hinge base 38 include a fixed sleeve 371, a rolling bearing 372, and an abutment spring 373. The fixed sleeve 371 is fixed to the side wall of the base 30 and has an opening facing the support assembly; the rolling bearing 372 is disposed inside the fixed sleeve 371; the abutment spring 373 is disposed inside the fixed sleeve 371.

[0072] Wherein, the rolling bearing 372 in the first hinge seat 37 is sleeved on the outer periphery of the first adjusting shaft 31, and the abutting spring 373 abuts against the shaft end of the first adjusting shaft 31; the rolling bearing 372 in the second hinge seat 38 is sleeved on the outer periphery of the second adjusting shaft 34, and the abutting spring 373 abuts against the shaft end of the second adjusting shaft 34.

[0073] It is easy to conceive that the inner ring of the rolling bearing 372 is interference-fitted with the corresponding adjusting shaft and can be axially positioned by the shaft shoulder; the outer ring of the rolling bearing 372 is transition / interference-fitted with the fixed sleeve 371 and is axially limited by the step inside the fixed sleeve 371. The shaft end of the adjusting shaft passes through the inner hole of the rolling bearing 372 and is tightly clamped to its inner ring. When rotating, the inner ring rotates synchronously with the adjusting shaft, while the outer ring remains stationary.

[0074] In this embodiment, the rolling bearing 372 transforms sliding friction into rolling friction, significantly reducing the rotational resistance of the adjusting shaft, thereby ensuring that the output torque of the adjusting motor 50 is lower and the power consumption is lower. The abutment spring 373 continuously presses against the end of the adjusting shaft, which can accommodate the slight axial movement of the adjusting shaft and buffer the impact on the adjusting shaft in the axial direction, avoiding bending of the adjusting shaft and deformation of the bearing, and reducing the load and failure rate of the adjusting motor 50.

[0075] In some embodiments, a specific implementation of the above-described adjustment frame may employ, as follows: Figures 1 to 3 The structure is shown. Both the first adjusting frame 33 and the second adjusting frame 36 include a hinge shaft 301, multiple sliding rods 302, and a top rod 303. The multiple sliding rods 302 are rotatably connected to the hinge shaft 301, and are spaced apart along the axial direction of the hinge shaft 301. The sliding rods 302 extend vertically and slide against the side wall of the base 30. The top rod 303 is located above the base 30 and abuts against the bottom surface of the mounting platform 10. The top rod 303 is fixedly connected to the top ends of the multiple sliding rods 302.

[0076] It is easy to imagine that the hinge shaft 301 on the first adjusting frame 33 is fixedly connected to the first adjusting rod 32, and the hinge shaft 301 on the second adjusting frame 36 is fixedly connected to the second adjusting rod 35. When the first adjusting rod 32 swings, the height of the end of the first adjusting rod 32 changes, thereby driving the corresponding first adjusting frame 33 to rise and fall; the same applies to the second adjusting frame 36.

[0077] In this embodiment, by setting a top rod 303 on the top of multiple sliding rods 302, the contact area with the mounting platform 10 is increased, improving the stability of the adjustment process of the mounting platform 10. During the lifting and lowering adjustment of the mounting platform 10, multiple sliding rods 302 are lifted synchronously, distributing the force at a single point and preventing the sliding rods 302 from being overloaded or jammed. The structural design of multiple sliding rods 302 and top rods 303 can improve the bending and compressive resistance of the adjustment frame, withstand the heavy load of the box-type substation 20, and is not easily deformed during long-term use.

[0078] Correspondingly, the base 30 also needs to have sliding holes corresponding to multiple sliding rods 302, sliding grooves corresponding to hinge shafts 301, and grooves corresponding to top rods 303 inside. The sliding holes penetrate the side wall of the base 30 in the vertical direction, and their number and position correspond to the sliding rods 302. The sliding rods 302 are fitted into the sliding holes with clearance. The sliding grooves are opened in the inner side wall of the base 30 in the vertical direction. The hinge shafts 301 are located in the sliding grooves and their positions change with the rise and fall of the corresponding sliding rods 302. The grooves are opened on the upper surface of the base 30, and the top rods 303 are placed in the grooves to ensure that they do not protrude from the upper surface of the base 30.

[0079] By incorporating sliding holes, grooves, and recesses, the sliding process of the slide rod 302 can be guided, further strengthening the structure and improving the stability of the lifting process. The groove provides vertical movement space for the hinge shaft 301, accommodating the displacement of the adjusting rod. When the top rod 303 is located within the recess, it does not protrude from the upper surface of the base 30, ensuring the stable placement of the mounting platform 10.

[0080] Specifically, a rubber pad 304 is provided on the top of the top rod 303. The rubber pad 304 can completely cover the top surface of the top rod 303, or multiple pads can be evenly arranged along the length of the top rod 303. The rubber pad 304 flexibly contacts the bottom surface of the mounting platform 10, avoiding local stress concentration and deformation of the mounting platform 10 caused by the rigid single-point pressing of the top rod 303; during the leveling process, the rubber pad 304 can absorb rigid impacts and vibrations, preventing the lifting force from being directly transmitted and damaging the mounting platform 10, the tilt sensor 60, and internal electrical components, thereby improving structural durability.

[0081] In practical use, due to the small adjustment angle, the push rod 303 will not separate from the mounting platform 10. To ensure that the push rod 303 acts on the center of the side of the mounting platform 10, the top surface of the push rod 303 is an arc surface that bulges upward in the middle. In this case, the rubber pad 304 can also be set only at the highest point of the arc surface.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
