An automation precise control device for substation commissioning

Abstract

This invention discloses an automated precision control device for substation commissioning, relating to the field of substation commissioning technology. It includes a prefabricated substation with symmetrically arranged lifting components inside the cavity. An angle adjustment component is located at the top of the moving plate, and each first guide plate is parallel to the side of the base top. The tilt of the rotating plate is adjusted by the angle adjustment component. A second guide plate is located at the top of the rotating plate. As the slider moves, the rotating rod rotates, which in turn rotates the fixed plate connected to it, thereby adjusting the tilt of the rotating plate and the second guide plate. This achieves adaptive adjustment of the guide angle. The vertical downward force ensures the prefabricated substation is stably positioned, preventing it from being suspended in mid-air. The lateral force along the inclined surface of the second guide plate allows the subfabricated substation to actively push back along the inclined surface to a preset path when it deviates, achieving self-correcting guidance.

Description

Technical Field

[0001] This invention relates to the field of substation commissioning technology, specifically to an automated and precise control device for substation commissioning. Background Technology

[0002] Substation equipment plays a vital role in social production and daily life, determining the level of economic development. Therefore, proper installation and commissioning of substation equipment is essential. Installation and commissioning is the testing process after equipment installation, a necessary procedure before use. It serves as a quality check, ensuring that only qualified equipment can be safely put into use, thus preventing unqualified equipment from causing unnecessary problems in subsequent work. The automated precision control device for the installation and commissioning of prefabricated substations achieves intelligent operation throughout the entire process through multi-dimensional technology integration. Its core working principle can be summarized in three major modules: the perception layer, the control layer, and the execution layer, along with a collaborative mechanism.

[0003] Traditionally, the installation and commissioning of substation equipment are carried out on crane platforms. During this process, crane operators rely on hand gestures to transport the equipment to the top of an anti-static floor. Then, multiple people manually hold the equipment in place to align it in the designated location. Due to the size of the substation and external environmental factors, manual placement of the equipment by hand and visual inspection during crane transport can lead to low precision between the installation location and the equipment, resulting in inconsistent commissioning positions and hindering the installation and commissioning process. Furthermore, traditional substation equipment installation guides are often fixed and exposed, requiring manual handling and assembly (low efficiency and high labor intensity), posing a risk of accidental contact and damage. When not in use, these guides occupy space, are susceptible to environmental corrosion, and cannot accommodate prefabricated substation boxes of varying weights. When the box collides with the guide, there is no buffering, and the rigid impact is directly transmitted to the box, potentially damaging internal components.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing automated precision control devices used for substation commissioning. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide an automated and precise control device for substation commissioning to solve the aforementioned problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated precision control device for substation commissioning, comprising a prefabricated substation, a base fixed to the bottom of the prefabricated substation, a cavity inside the base, lifting components symmetrically arranged inside the cavity, a rack symmetrically and offset on the inner wall of the top of the base, a gear meshing on one side of the rack, a movable plate on one side of the gear, and the position of the movable plate being adjusted by the lifting components, an angle adjustment component on the top of the movable plate, a first guide plate fixed to one side of the movable plate, and each of the first guide plates being arranged parallel to the side of the top of the base, a rotating plate hinged to one end of the first guide plate, and the tilt of the rotating plate being adjusted by the angle adjustment components, a second guide plate on the top of the rotating plate, and the second guide plates at the top of the base being symmetrically and offset, a buffer component being arranged between the rotating plate and the second guide plate, and the buffer component making the rotating plate and the second guide plate elastically connected, a plurality of rolling columns rotatably connected at equal distances on one side of the first guide plate, and a plurality of rolling columns rotatably connected at equal distances on the top of the second guide plate.

[0007] Preferably, the lifting assembly includes a push rod disposed inside a cavity in the base, an electric telescopic rod fixed to one side of the push rod, and push blocks fixed to both ends of the push rod, a roller slidably connected to the top of the push block, and a lifting rod rotatably connected to the roller through a connecting shaft, the top of the lifting rod being fixedly connected to a movable plate.

[0008] Preferably, the contact surface between the push block and the roller is an inclined surface, and the lifting rod is slidably connected to the base for limiting.

[0009] Preferably, a first spring is provided inside the cavity of the base, one end of the first spring is fixedly connected to the inner wall of the cavity of the base, and the other end of the first spring is fixedly connected to a protruding position on the outer wall of the lifting rod.

[0010] Preferably, the angle adjustment assembly includes a lead screw fixedly connected to one end of a gear, a slider connected to the outer wall of the lead screw by a thread, connecting rods fixed on both sides of the slider, a rotating rod rotatably connected to one end of the connecting rod, and a fixed plate rotatably connected to the other end of the rotating rod via a connecting shaft, the top end of the fixed plate being fixedly connected to the rotating plate.

[0011] Preferably, the connecting rod passes through a fixed frame, the fixed frame has a cavity for sliding with the connecting rod, and the bottom end of the fixed frame is fixedly connected to the movable plate, and the slider is limited and slidably connected to the movable plate.

[0012] Preferably, the buffer assembly includes a fixed seat symmetrically fixed to the top of the rotating plate, an elastic telescopic rod rotatably connected to one side of the fixed seat, a fixed block fixed to one end of the elastic telescopic rod, a sliding rod rotatably connected to one side of the fixed block, and the sliding rod is slidably connected to the rotating plate, a fixed column fixed to the top of the sliding rod, and a second guide plate fixed to the top of the fixed column.

[0013] Preferably, a second spring is wound around the outer wall of the sliding rod, one end of the second spring is fixedly connected to a protruding position on the outer wall of the sliding rod, and the other end of the second spring is fixedly connected to the top of the rotating plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention uses an electric telescopic rod to drive a push rod, which in turn drives a push block to move synchronously. Since the contact surface between the push block and the roller is inclined, the movement of the push block drives the roller and the lifting rod to move up and down, thereby driving the moving plate to move synchronously. This causes the first guide plate and the rotating plate, which are fixed to the moving plate, to rise synchronously, waiting for the prefabricated substation to be positioned and connected. This allows the guide installation device to be opened when the prefabricated substation is at the top of the base, facilitating precise installation of both and significantly shortening the deployment time of the guide device. When installation is not required, the guide installation device retracts into the base, preventing accidental contact by personnel and isolating the guide components from external dust and rainwater, thus extending the service life of the device.

[0016] 2. This invention uses meshing gears and racks to drive a lead screw to rotate. The rotation of the lead screw causes the slider to slide, and as the slider moves, it drives a rotating rod to rotate, which in turn drives a fixed plate connected to it to rotate. This adjusts the tilt of the rotating plate and the second guide plate, achieving adaptive adjustment of the guide angle. When the weight of the prefabricated substation is greater, the tilt of the rotating plate and the second guide plate needs to be increased accordingly. During the hoisting and placement of the prefabricated substation, slight lateral deviation (deviation from the target installation position) may occur due to the influence of crane accuracy, wind force, etc. At this time, the tilt angle of the second guide plate can decompose the vertical gravity of the prefabricated substation into two components. The vertical downward component ensures that the prefabricated substation is placed steadily and avoids suspension. The lateral component along the inclined surface of the second guide plate allows the prefabricated substation to be actively pushed back to the preset path along the inclined surface when it deviates, achieving self-correcting guidance. In addition, the top of both the first guide plate and the second guide plate are rotatably connected to rolling columns, which can greatly reduce the resistance when the prefabricated substation is placed, avoiding scratches or guide jamming caused by excessive friction.

[0017] 3. In this invention, the movement of the second guide plate causes the fixed column to move synchronously, which in turn causes the sliding rod to slide within the rotating plate. At this time, the second spring is in a compressed state, and the movement of the sliding rod causes the fixed block to move synchronously, which in turn causes the elastic telescopic rod to stretch, forming a double buffer. The elastic potential energy released by the second spring and the elastic telescopic rod buffers the impact force on the second guide plate, avoiding rigid contact between the second guide plate and the prefabricated substation, and preventing damage to the internal parts of the prefabricated substation. When the bottom of the prefabricated substation contacts the base and the impact force disappears, the second spring releases its elastic potential energy, pushing the sliding rod to reset. At the same time, the elastic telescopic rod retracts and resets, causing the second guide plate to return to its initial guiding position, completing the buffer closed loop and ensuring that it can continue to play a guiding role even if there is a slight deviation in the future.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 9 This invention provides a technical solution: an automated precision control device for substation commissioning, comprising a prefabricated substation 1, a base 2 fixed to the bottom of the prefabricated substation 1, a cavity inside the base 2, lifting components symmetrically arranged inside the cavity, racks 4 symmetrically arranged at offset positions on the inner wall of the top of the base 2, a gear 5 meshing on one side of the racks 4, a movable plate 6 arranged on one side of the gear 5, and the position of the movable plate 6 being adjusted by the lifting components, an angle adjustment component at the top of the movable plate 6, and a first guide plate 10 fixed to one side of the movable plate 6, with each first guide plate 10 parallel to the bottom. The top side of the base 2 has a first guide plate 10 with a rotating plate 8 hinged to one end. The tilt of the rotating plate 8 can be adjusted by an angle adjustment component. A second guide plate 11 is provided on the top of the rotating plate 8. The second guide plates 11 at the top of the base 2 are arranged in a staggered and symmetrical manner. A buffer component is provided between the rotating plate 8 and the second guide plate 11. The buffer component makes the rotating plate 8 and the second guide plate 11 elastically connected. Multiple rolling columns 12 are rotatably connected at equal distances on one side of the first guide plate 10. Multiple rolling columns 12 are rotatably connected at equal distances on the top of the second guide plate 11.

[0030] In specific implementation, the device uses base 2 as the installation foundation. First, the position of the moving plate 6 is adjusted by the lifting components symmetrically arranged in the cavity of base 2, which drives the first guide plate 10, which is fixed to one side of the moving plate 6 and parallel to the top side of base 2, to rise and fall synchronously, realizing the expansion and contraction of the guide structure. The angle adjustment component at the top of the moving plate 6, combined with the rack 4 and meshing gear 5 symmetrically arranged at the top inner wall of base 2, adjusts the tilt of the rotating plate 8, which is hinged to one end of the first guide plate 10, thereby changing the tilt angle of the second guide plate 11 at the top of the rotating plate 8. At the same time, the buffer component between the rotating plate 8 and the second guide plate 11 makes the two form an elastic connection, which can buffer the impact force when the box-type substation 1 is placed. In addition, the multiple rolling columns 12 equidistantly rotated at the top of the first guide plate 10 and the second guide plate 11 can reduce the contact friction between the box-type substation 1 and the guide plate, ultimately assisting the box-type substation 1 to be accurately and safely placed on the top of base 2.

[0031] As a further embodiment of the present invention, the lifting assembly includes a push rod 301 disposed inside the cavity of the base 2. An electric telescopic rod is fixed to one side of the push rod 301, and push blocks 302 are fixed to both ends of the push rod 301. A roller 303 is slidably connected to the top of the push block 302. The roller 303 is rotatably connected to the lifting rod 304 through a connecting shaft. The top of the lifting rod 304 is fixedly connected to the moving plate 6.

[0032] In practice, the electric telescopic rod provides power to move the push rod 301 inside the cavity of the base 2. The push blocks 302 fixed at both ends of the push rod 301 move synchronously with the push rod 301. The roller 303 sliding at the top of the push block 302 is displaced under the action of the push block 302. The lifting rod 304, which is rotatably connected to the roller 303 through the connecting shaft, moves accordingly, thereby driving the movable plate 6 fixed at the top to rise and fall, thus completing the adjustment of the position of the movable plate 6.

[0033] As a further embodiment of the present invention, the contact surface between the push block 302 and the roller 303 is an inclined surface, and the lifting rod 304 is slidably connected to the base 2.

[0034] In practice, when the push block 302 moves with the push rod 301, the contact surface between the push block 302 and the roller 303 is an inclined plane. The guiding effect of the inclined plane will convert the horizontal movement of the push block 302 into the vertical movement of the roller 303. At the same time, since the lifting rod 304 and the base 2 are connected by a limit sliding connection, only vertical displacement is allowed. The vertical movement of the roller 303 can stably drive the lifting rod 304, which is rotatably connected to it through the connecting shaft, to make vertical lifting and lowering, thereby accurately controlling the lifting position of the moving plate 6 fixed at the top of the lifting rod 304.

[0035] As a further embodiment of the present invention, a first spring 305 is provided inside the cavity of the base 2. One end of the first spring 305 is fixedly connected to the inner wall of the cavity of the base 2, and the other end of the first spring 305 is fixedly connected to the protruding position of the outer wall of the lifting rod 304.

[0036] In specific implementation, one end of the first spring 305 inside the cavity of the base 2 is fixed to the inner wall of the cavity, and the other end is fixed to the protruding position of the outer wall of the lifting rod 304. When the push block 302 drives the roller 303 to make the lifting rod 304 move vertically upward, the protruding position of the outer wall of the lifting rod 304 will compress the first spring 305, so that it stores elastic potential energy. When the external force driving the electric telescopic rod to reset disappears, the first spring 305 releases elastic potential energy, which can drive the lifting rod 304 to reset, thereby realizing the reset and retraction of the moving plate 6 and the upper guide assembly.

[0037] As a further embodiment of the present invention, the angle adjustment component includes a lead screw 701 fixedly connected to one end of the gear 5, a slider 702 connected to the outer wall of the lead screw 701 by a thread, connecting rods 703 fixed on both sides of the slider 702, a rotating rod 704 rotatably connected to one end of the connecting rod 703, and a fixing plate 705 rotatably connected to the other end of the rotating rod 704 by a connecting shaft, with the top end of the fixing plate 705 fixedly connected to the rotating plate 8.

[0038] In practice, when gear 5 rotates, it drives the lead screw 701, which is fixedly connected to one end of it, to rotate synchronously. The slider 702, which is connected to the outer wall of the lead screw 701 by a thread, slides along the axis of the lead screw 701 under the action of the rotation of the lead screw 701. The connecting rods 703 fixed on both sides of the slider 702 move synchronously with the slider 702, thereby driving the rotating rod 704, which is rotatably connected at one end, to rotate around the connection point. The fixed plate 705, which is rotatably connected to the other end of the rotating rod 704 by a connecting shaft, will change angle under the action of the rotation of the rotating rod 704. Finally, the tilt of the rotating plate 8 is adjusted by the rotating plate 8 fixed at the top of the fixed plate 705.

[0039] As a further embodiment of the present invention, the connecting rod 703 passes through the fixed frame 706, the fixed frame 706 has a cavity that cooperates with the sliding of the connecting rod 703, and the bottom end of the fixed frame 706 is fixedly connected to the moving plate 6, and the slider 702 is limited and slidably connected to the moving plate 6.

[0040] In specific implementation, the cavity of the fixed frame 706 fixed to the bottom of the movable plate 6 provides a sliding guide for the connecting rod 703 passing through it, restricting the connecting rod 703 to move only along the direction of the cavity, and preventing deviation when the slider 702 drives the connecting rod 703 to move. At the same time, the limiting sliding connection between the slider 702 and the movable plate 6 further restricts the slider 702 to slide only along the preset direction on the surface of the movable plate 6. The two work together to ensure that the movement of the slider 702 and the connecting rod 703 is stable and accurate when the lead screw 701 rotates, providing a reliable motion trajectory guarantee for the subsequent rotation rod 704 to drive the fixed plate 705 and the rotating plate 8 to adjust the tilt angle.

[0041] As a further embodiment of the present invention, the buffer assembly includes a fixed seat 901 symmetrically fixed to the top of the rotating plate 8. An elastic telescopic rod 902 is rotatably connected to one side of the fixed seat 901. A fixed block 903 is fixed to one end of the elastic telescopic rod 902. A sliding rod 904 is rotatably connected to one side of the fixed block 903, and the sliding rod 904 is slidably connected to the rotating plate 8. A fixed post 905 is fixed to the top of the sliding rod 904, and a second guide plate 11 is fixed to the top of the fixed post 905.

[0042] In specific implementation, the fixed base 901 symmetrically fixed at the top of the rotating plate 8 provides rotational support for the elastic telescopic rod 902. When the second guide plate 11 is impacted by the box-type substation 1, the second guide plate 11 will drive the fixed column 905 fixed at the top to move synchronously. The fixed column 905 then pulls the sliding rod 904 fixed to it to slide along the rotating plate 8. When the sliding rod 904 slides, it will drive the fixed block 903 rotatably connected on one side to move. The fixed block 903 then pulls the elastic telescopic rod 902 fixed to it to rotate around the fixed base 901 and undergo telescopic deformation. The deformation of the elastic telescopic rod 902 absorbs the impact energy, thereby achieving buffer protection for the second guide plate 11 and the box-type substation 1.

[0043] As a further embodiment of the present invention, a second spring 906 is wound around the outer wall of the sliding rod 904. One end of the second spring 906 is fixedly connected to a protruding position on the outer wall of the sliding rod 904, and the other end of the second spring 906 is fixedly connected to the top of the rotating plate 8.

[0044] In practice, when the second guide plate 11 is impacted and causes the fixed column 905 and the sliding rod 904 to slide along the rotating plate 8, the protruding position of the outer wall of the sliding rod 904 will exert a compressive force on the second spring 906 wrapped around its outer wall, causing the second spring 906 to deform and store elastic potential energy. Together with the elastic telescopic rod 902, it absorbs the impact energy and enhances the buffering effect. When the impact force disappears, the second spring 906 releases its elastic potential energy, pushes the sliding rod 904 to reset, and then drives the fixed column 905 and the second guide plate 11 back to their initial positions, ensuring that the subsequent guiding function is normal.

[0045] Working Principle: When using the automated precision control device for substation commissioning, the prefabricated substation 1 is first transported to the top of the base 2 by a crane. After the prefabricated substation 1 is hoisted above the base 2, it is crucial to control the accuracy and levelness of the descent. The descent speed should be uniform and slow. Simultaneously, the electric telescopic rod is activated, which drives the push rod 301 to move. The movement of the push rod 301 causes the push blocks 302 on both sides to move synchronously. Since the contact surface between the push block 302 and the roller 303 is inclined, the movement of the push block 302 causes the roller 303 to slide at the top of the push block 302. The lifting rod 304 set at the top of the roller 303 is in a limiting sliding connection with the base 2. The movement of the lifting rod 304 causes it to move up and down. At this time, the first spring 305, which is located at the protruding position on the outer wall of the lifting rod 304 and the inner wall of the cavity opened in the base 2, is in a compressed state (when the electric telescopic rod is reset, the lifting rod 304 releases its elastic potential energy through the first spring 305 to reset). The top of the lifting rod 304 is fixed with a moving plate 6, which in turn drives the moving plate 6 to move synchronously, so that the first guide plate 10 fixed with the moving plate 6 and the rotating plate 8 hinged with the first guide plate 10 rise synchronously (when the electric telescopic rod is not started, the rotating plate 8 and the second guide plate 11 at its top are parallel to the top plane of the base 2 and retract into the base 2), waiting for the box-type substation 1 to be positioned and connected. When the box-type substation 1 is located at the top of the base 2, the guide installation device is opened to facilitate the precise installation of both. When installation is not required, the guide installation device is retracted into the base 2 to prevent accidental contact by personnel and affect its service life.

[0046] When the movable plate 6 rises, the gear 5 at its top moves synchronously. Since a rack 4 meshes with one side of the gear 5, its movement drives the gear 5 to rotate via the rack 4, which in turn drives the lead screw 701 fixed at one end to rotate. The rotation of the lead screw 701, through the threads on its outer wall, drives the slider 702 to slide at the top of the movable plate 6. Because the fixed frame 706 at the top of the movable plate 6 has a cavity for sliding with the connecting rod 703, when the connecting rod 703 moves with the slider 702, it drives the rotating rod 704 to rotate, thereby driving the slider 702 to slide. The fixed plate 705 of the rotatable connection rotates, thereby adjusting the tilt of the rotating plate 8 and the second guide plate 11 set on its top. When the weight of the prefabricated substation 1 is greater, the tilt of the rotating plate 8 and the second guide plate 11 needs to be increased accordingly. During the hoisting and placement process of the prefabricated substation 1, it may experience slight lateral displacement (deviation from the target installation position) due to the influence of crane accuracy, wind force, etc. At this time, the tilt angle of the second guide plate 11 can decompose the vertical gravity of the prefabricated substation 1 into two components. The vertically downward component ensures the stability of the prefabricated substation. The positioning avoids suspension. The lateral force along the inclined surface of the second guide plate 11 allows the box to actively push back along the inclined surface to the preset path when it deviates, achieving self-correcting guidance. When the weight of the box increases, the device controls the extension of the electric telescopic rod through a preset program or feedback from the weight sensor, increasing the upward stroke of gear 5. Only by increasing the tilt angle of the second guide plate 11 can the lateral correction force increase synchronously, ensuring that the lateral correction force is sufficient to counteract friction and prevent jamming. Furthermore, the four second guide plates 11 on the top of the base 2 are staggered and symmetrical. The system is designed so that no matter which direction the prefabricated substation 1 deviates, as long as it comes into contact with any of the second guide plates 11, it can be pushed to the correct installation position by the lateral correction component force, achieving 360-degree self-correction without dead angles and ensuring docking accuracy. When the prefabricated substation 1 is in the correct installation position, its outer wall comes into contact with the four first guide plates 10, and the top of the first guide plates 10 and the second guide plates 11 are rotatably connected with rolling columns 12, which can reduce the contact friction between the prefabricated substation 1 and the first guide plates 10 and the second guide plates 11 through the rolling columns 12.

[0047] When the bottom of the prefabricated substation 1 contacts the second guide plate 11, it exerts an impact force on the second guide plate 11, causing the second guide plate 11 to move towards the rotating plate 8. When the second guide plate 11 moves, it drives the fixed column 905 at its bottom to move synchronously, thereby driving the sliding rod 904, which is fixedly connected to the fixed column 905, to slide inside the rotating plate 8. At this time, the second spring 906, located at the protruding position on the outer wall of the sliding rod 904 and the top of the rotating plate 8, is in a compressed state, and when the sliding rod 904 moves, it drives the fixed column 905 on both sides to rotate. The fixed block 903 moves synchronously, which in turn causes the elastic telescopic rod 902, which is fixedly connected to the fixed block 903, to stretch (the elastic telescopic rod 902 is rotatably connected to the fixed base 901), forming a double buffer. The elastic potential energy released by the second spring 906 and the elastic potential energy released by the elastic telescopic rod 902 buffers the impact force on the second guide plate 11, avoiding rigid contact between the second guide plate 11 and the box-type substation 1, and preventing damage to the internal parts of the box-type substation 1. When the box-type substation 1 is placed in the correct position (the bottom end contacts the base 2), after the impact force disappears, the second spring 906 releases elastic potential energy, pushing the sliding rod 904 to reset. At the same time, the elastic telescopic rod 902 retracts and resets, causing the second guide plate 11 to return to the initial guide position, completing the buffer closed loop, and ensuring that it can continue to play a guiding role if there is a slight deviation in the future.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
