[0003] The application field of integrated transformer distribution cabinet is relatively wide, including the field of petrochemical production, where it is used to supply power and distribute power to oil production equipment.

[0004] In the field of petrochemical processing, traditional transformer distribution cabinets are usually installed on the ground. Due to the limited space resources in the petrochemical plant area, ground-mounted transformer distribution cabinets occupy valuable ground space, limiting the layout and expansion of other facilities. Summary of the invention

[0005] In order to save space utilization of a power distribution cabinet, the present application provides an integrated transformer power distribution cabinet.

[0006] The integrated transformer distribution cabinet provided in this application adopts the following technical solution: An integrated transformer distribution cabinet comprises an underground box and a distribution cabinet body, wherein the underground box is pre-buried in a pit in the ground, the top of the underground box is open, a sliding plate is provided inside the underground box for sliding along the vertical direction, the distribution cabinet body is arranged on the upper surface of the sliding plate, the underground box is provided with a driving assembly, the driving assembly is used to drive the sliding plate to move, and a cover plate is hinged on the top of the underground box, and the cover plate is used to seal the opening of the underground box.

[0007] Through the above scheme, the integrated transformer distribution cabinet achieves the dual goals of concealed installation and convenient maintenance of the distribution cabinet body. The buried box is pre-buried in a pit on the ground, which not only reduces the occupation of ground space, but also effectively protects the distribution cabinet body from external environmental factors, such as bad weather, human damage, etc. The setting of the sliding plate enables the distribution cabinet body to slide in the vertical direction. Combined with the use of the drive assembly, the distribution cabinet body can be easily lifted to the surface when needed, which is convenient for daily inspection, maintenance or troubleshooting without complicated excavation work, greatly improving maintenance efficiency and convenience. The hinged design and sealing function of the cover ensure the sealing of the buried box in the non-maintenance state, preventing rainwater, dust and other external impurities from entering, further protecting the distribution cabinet body, extending its service life, and keeping the ground clean and beautiful.

[0008] Preferably, the driving assembly includes a driving motor and a first crank-connecting rod mechanism, the driving motor is installed on the back side of the underground box, the turntable of the first crank-connecting rod mechanism is rotatably supported by the side wall of the underground box, the output shaft of the driving motor drives the turntable of the first crank-connecting rod mechanism to rotate, and the connecting rod of the first crank-connecting rod mechanism is hinged to the sliding plate.

[0009] Through the above scheme, the drive motor is installed on the back of the underground box. This location selection not only saves the internal space of the underground box, but also facilitates the installation and maintenance of the motor. The rotation of the turntable of the first crank-connecting rod mechanism is carried by the side wall of the underground box, ensuring the stability and reliability of the mechanism. The output shaft of the drive motor directly drives the turntable of the first crank-connecting rod mechanism to rotate. This direct drive method improves the transmission efficiency and reduces energy loss. The connecting rod of the first crank-connecting rod mechanism is hinged to the sliding plate. This hinge method enables the movement of the connecting rod to be effectively converted into the vertical sliding of the sliding plate, thereby realizing the lifting and lowering of the distribution cabinet body. This driving scheme is not only compact in structure and easy to operate, but also can ensure the smooth movement of the sliding plate and the accuracy of positioning, which provides great convenience for the daily maintenance and troubleshooting of the distribution cabinet body.

[0010] Preferably, a guide groove is provided on the inner wall of the buried box in the vertical direction, a guide rod is fixed to the side wall of the sliding plate, and the guide rod is slidably disposed in the guide groove in the vertical direction.

[0011] Through the above scheme, the smooth sliding of the sliding plate in the vertical direction is ensured, and the cooperation between the guide rod and the guide groove plays a role of precise guidance, effectively preventing the lateral deviation of the sliding plate during movement, and ensuring the stability and positioning accuracy of the sliding plate.

[0012] Preferably, an external gear is rotatably carried on the sliding plate, the distribution cabinet body is fixed to the upper surface of the external gear, and a transmission gear is rotatably carried on the inner wall of the buried box. When the sliding plate moves upward to the top, the transmission gear and the external gear are meshed with each other, and a first transmission assembly is arranged between the drive motor and the transmission gear.

[0013] Through the above solution, when the sliding plate moves to the top, the transmission gear meshes with the external gear, and the driving motor drives the transmission gear to rotate through the first transmission assembly. Due to the meshing of the transmission gear and the external gear, the external gear rotates accordingly, thereby driving the distribution cabinet body fixed thereon to change the angle. By adjusting the angle of the distribution cabinet body, it is easier to access various parts of the equipment, especially those areas that are difficult to reach in a vertical position. This allows maintenance personnel to more conveniently inspect, clean and replace parts, thereby improving work efficiency.

[0014] Preferably, the first transmission assembly includes a first pulley transmission mechanism and two mutually meshing bevel gears, a first inner ratchet mechanism is arranged between the output shaft of the drive motor and the first crank-connecting rod mechanism, a second inner ratchet mechanism is arranged on the buried box, the first pulley transmission mechanism is connected between the output shaft of the drive motor and the second inner ratchet mechanism, one of the bevel gears is synchronously connected to the first pulley transmission mechanism, and the other bevel gear is coaxially arranged with the transmission gear.

[0015] Through the above scheme, the first transmission component of the integrated transformer distribution cabinet adopts a first pulley transmission mechanism and two mutually meshing bevel gears, combined with an internal ratchet mechanism, to achieve effective transmission and direction conversion of the output shaft power of the drive motor. Specifically, a first internal ratchet mechanism is arranged between the output shaft of the drive motor and the first crank-connecting rod mechanism. This design ensures unidirectional transmission of power, prevents reverse drive, and improves the safety and reliability of the system. The second internal ratchet mechanism arranged on the buried box is connected to the first pulley transmission mechanism, further ensuring the smoothness of power transmission and the accuracy of direction control.

[0016] Preferably, a movable plate is slidingly provided on the side wall of the buried box, a wire group connector is installed on the movable plate, a terminal block is fixed on the side wall of the power distribution cabinet body, the wire group connector is plugged into the terminal block, and the wire group connector connects the electrical signal of the power distribution cabinet body to other equipment through the signal line pre-buried underground.

[0017] The above solution not only ensures the high efficiency and stability of electrical signal transmission, but also demonstrates high flexibility and convenience in practical applications. When the power distribution cabinet needs to be inspected or maintained, the movable plate can easily slide along the side wall of the buried box to quickly separate the wire group connector from the terminal block, thus providing great convenience for inspection and maintenance work.

[0018] Preferably, a second transmission assembly is arranged between the cover plate and the movable plate, the second transmission assembly includes a second pulley transmission mechanism and a second crank-connecting rod mechanism, the turntable of the second crank-connecting rod mechanism is rotatably supported on the side wall of the buried box, the second pulley transmission mechanism is connected between the rotating shaft of the cover plate and the turntable of the second crank-connecting rod mechanism, and the connecting rod of the second crank-connecting rod mechanism is hinged to the movable plate.

[0019] Through the above scheme, not only the synchronous sliding of the movable plate when the cover is opened and closed is achieved, which greatly improves the convenience of operation, but also the entire transmission process is smooth and reliable, effectively avoiding safety hazards caused by improper operation or mechanical failure.

[0020] Preferably, a guide rod is fixed to the side wall of the movable plate, a guide groove is provided on the side wall of the buried box, and the guide rod is slidably disposed in the guide groove along a horizontal direction.

[0025] The above solution not only effectively prevents external impurities such as dust and moisture from entering the underground box and causing damage to the internal electrical components, but also significantly improves the safety and reliability of the entire power distribution system.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The sliding plate and driving assembly inside the underground box allow the distribution cabinet body to move in the vertical direction through the driving assembly when maintenance or operation is required, so that the distribution cabinet body rises above the ground, which is convenient for the staff to operate. When not in use, the distribution cabinet body can be lowered below the ground, and the cover plate seals the opening of the underground box to keep the ground flat and safe, and then the main part of the integrated transformer distribution cabinet is pre-buried below the ground, which effectively solves the problem of tight space resources in the petrochemical production field; 2.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0032] The present application embodiment discloses an integrated transformer distribution cabinet. Figure 1 and Figure 2 An integrated transformer distribution cabinet includes an underground box 1 and a distribution cabinet body 2. The underground box 1 is arranged in a rectangular shape. The underground box 1 is pre-buried in a pit on the ground. In this embodiment, the pre-buried process of the underground box 1 mainly includes: first, excavating a pit of a size that meets the design requirements; second, waterproofing the pit to ensure the waterproof performance of the underground box 1; then, placing the underground box 1 in the pit, and fixing the box body with positioning ribs and support components to ensure its stability and correct position; then, reserving a cable channel and preparing for electrical connection; then, pouring concrete to fill the gap between the underground box 1 and the pit to improve the structural stability.

[0033] Furthermore, a sliding plate 3 is provided inside the underground box 1 for sliding along the vertical direction, the sliding plate 3 is arranged horizontally, the distribution cabinet body 2 is arranged on the upper surface of the sliding plate 3, the underground box 1 is provided with a driving assembly 5, the driving assembly 5 is used to drive the sliding plate 3 to move along the vertical direction, and a cover plate 4 is hinged on the top of the underground box 1, and the cover plate 4 is used to seal the opening of the underground box 1.

[0034] Therefore, the sliding plate 3 and driving assembly 5 inside the buried box 1 allow the distribution cabinet body 2 to move in the vertical direction through the driving assembly 5 when maintenance or operation is required, so that the distribution cabinet body 2 rises above the ground to facilitate operation by the staff. When not in use, the distribution cabinet body 2 can be lowered to below the ground, and the cover plate 4 seals the opening of the buried box 1 to keep the ground flat and safe, thereby pre-burying the main part of the integrated transformer distribution cabinet The buried box 1 is buried below the ground, effectively solving the problem of tight space resources in the petrochemical production field.

[0035] Specifically, the driving assembly 5 includes a driving motor 51 and a first crank-connecting rod mechanism 52. The driving motor 51 is installed on the back of the underground box 1, wherein a bearing frame 11 is fixed on the back of the underground box 1. The bearing frame 11 is composed of two arc-shaped plates 111, a horizontal plate 112 and an L-shaped plate 113. The two arc-shaped plates 111 are symmetrically arranged on the back of the underground box 1 and fixed to the underground box 1. The two ends of the horizontal plate 112 are respectively fixed to the inner arc surfaces opposite to the two arc-shaped plates 111. In addition, the L-shaped plate 113 is vertically fixed to the side wall of the horizontal plate 112, and the driving motor 51 is installed on the side wall of the L-shaped plate 113.

[0036] At the same time, the turntable of the first crank-connecting rod mechanism 52 is rotatably supported on the side wall of the underground box 1, wherein the turntable of the first crank-connecting rod mechanism 52 is correspondingly rotatably supported on the inner surfaces of the two opposite arc-shaped plates 111, and the output shaft of the drive motor 51 drives the turntable of the first crank-connecting rod mechanism 52 to rotate, and the connecting rod of the first crank-connecting rod mechanism 52 is hinged to the sliding plate 3, and a make way groove is provided on the back side of the underground box 1 along the vertical direction for the connection between the connecting rod of the first crank-connecting rod mechanism 52 and the sliding plate 3 to make way.

[0037] Correspondingly, in the integrated transformer power distribution cabinet, the action process of the drive assembly 5 is realized by the drive motor 51 and the first crank-connecting rod mechanism 52. When the power distribution cabinet body 2 needs to be lifted, the drive motor 51 is started, and its output shaft drives the turntable of the first crank-connecting rod mechanism 52 to rotate. The turntable is located on the inner surfaces of two opposite arc-shaped plates 111 and is fixed to the back of the underground box 1 by an L-shaped plate 113. As the turntable rotates, the connecting rod swings accordingly, and the connecting rod is hinged to the sliding plate 3, and the sliding plate 3 moves in the vertical direction through the swing of the connecting rod. The clearance groove set on the back of the underground box 1 ensures the smooth movement of the connection between the connecting rod and the sliding plate 3, avoiding structural interference. In this way, the power distribution cabinet body 2 on the sliding plate 3 can smoothly rise or fall in the vertical direction, realizing the vertical lifting function of the power distribution cabinet body 2.

[0038] Therefore, by adopting the combination of the drive motor 51 and the first crank-connecting rod mechanism 52, the integrated transformer power distribution cabinet realizes the efficient vertical lifting of the power distribution cabinet body 2. This design not only simplifies the operation process and improves the maintainability and safety of the equipment, but also effectively utilizes the underground space and solves the problem of tight space resources in the field of petrochemical production. When maintenance or operation is required, the power distribution cabinet body 2 can be quickly raised above the ground to facilitate the operation of the staff, and when not in use, the power distribution cabinet body 2 can be lowered below the ground, and the cover plate 4 seals the opening of the buried box 1 to keep the ground flat and safe. This innovative integrated design not only improves the flexibility and operational convenience of the equipment, but also optimizes the use of space. It is an important technological advancement in the modernization and efficiency of the power distribution system in the petrochemical industry.

[0039] Reference Figure 2 and Figure 3 Furthermore, a rod body 12 is fixed on the inner wall of the buried box 1 along the vertical direction, and a guide groove 121 is correspondingly opened on the rod body 12 along the vertical direction. At the same time, a guide rod 31 is fixed on the side wall of the sliding plate 3, and the guide rod 31 is slidably arranged in the guide groove 121 along the vertical direction. The cross-section of the guide rod 31 and the guide groove 121 is T-shaped, so that the guide rod 31 can be slidably arranged in the guide groove 121 along the vertical direction, which effectively limits the displacement of the sliding plate 3 in the horizontal direction and ensures the stability and accuracy of the sliding plate 3 during the lifting process.

[0040] On the other hand, an external gear 32 is rotatably carried on the sliding plate 3, and the external gear 32 is horizontally arranged. The axis of the external gear 32 is located at the center of the sliding plate 3. The distribution cabinet body 2 is fixed to the upper surface of the external gear 32. A first bearing seat 122 is fixed to the side wall of the rod body 12. A transmission gear 6 is rotatably carried on the first bearing seat 122, and the transmission gear 6 is horizontally arranged. When the sliding plate 3 moves upward to the top, the transmission gear 6 and the external gear 32 are meshed with each other, and a first transmission assembly 7 is arranged between the drive motor 51 and the transmission gear 6.

[0041] Correspondingly, when the sliding plate 3 moves to the top, the transmission gear 6 meshes with the outer gear 32. At this time, the driving motor 51 drives the transmission gear 6 to rotate through the first transmission assembly 7. Due to the meshing of the transmission gear 6 and the outer gear 32, the outer gear 32 rotates accordingly, thereby driving the distribution cabinet body 2 fixed thereon to change the angle. By adjusting the angle of the distribution cabinet body 2, it is easier to access various parts of the equipment, especially those areas that are difficult to reach in a vertical position. This allows maintenance personnel to more conveniently inspect, clean and replace parts, thereby improving work efficiency.

[0042] Specifically, the first transmission assembly 7 includes a first pulley transmission mechanism 71 and two mutually meshing bevel gears 72. A first inner ratchet mechanism 8 is arranged between the output shaft of the drive motor 51 and the first crank-connecting rod mechanism 52. The inner wheel of the first inner ratchet mechanism 8 is coaxially fixed with the output shaft of the drive motor 51, and the outer wheel of the first inner ratchet mechanism 8 is rotatably supported on the cross plate 112 and coaxially fixed with the turntable of the first crank-connecting rod mechanism 52.

[0043] In addition, a second inner ratchet mechanism 9 is provided on the buried box 1, and the first pulley transmission mechanism 71 is connected between the output shaft of the drive motor 51 and the second inner ratchet mechanism 9. Specifically, a second bearing seat 123 is fixed to the top of the rod body 12, and the outer wheel of the second inner ratchet mechanism 9 is rotatably supported on the second bearing seat 123, and the inner wheel of the second inner ratchet is coaxially fixed to one of the pulleys of the first pulley transmission mechanism 71.

[0044] At the same time, one of the bevel gears 72 is synchronously connected to the first pulley transmission mechanism 71. Specifically, the bevel gear 72 is coaxially fixed to the outer wheel of the second inner ratchet mechanism 9, and the other bevel gear 72 is rotatably supported on the first bearing seat 122 and is coaxially arranged with the transmission gear 6.

[0045] Therefore, the output shaft of the driving motor 51 rotates forward, and the power is first transmitted to the inner wheel of the first inner ratchet mechanism 8 fixed coaxially therewith. The first inner ratchet mechanism 8 allows the power to be transmitted from the inner wheel to the outer wheel. The outer wheel is coaxially fixed to the turntable of the first crank-connecting rod mechanism 52, so the power is further transmitted to the first crank-connecting rod mechanism 52. The first crank-connecting rod mechanism 52 converts the rotational motion into linear motion, driving the sliding plate 3 to move upward in the vertical direction. At the same time, the output shaft of the driving motor 51 transmits the power to the second inner ratchet mechanism 9 through the first pulley transmission mechanism 71. Due to the one-way transmission characteristics of the second inner ratchet mechanism 9, the transmission gear 6 remains stationary.

[0046] On the contrary, when the output shaft of the drive motor 51 reverses, due to the one-way transmission characteristics of the first inner ratchet mechanism 8, the first inner ratchet mechanism 8 prevents power from being transmitted back from the first crank-connecting rod mechanism 52 to the drive motor 51, ensuring that the sliding plate 3 can maintain its position unchanged after reaching the top, and the output shaft power of the drive motor 51 is transmitted to the inner wheel of the second inner ratchet mechanism 9 through the first pulley transmission mechanism 71. Due to the one-way transmission characteristics of the second inner ratchet mechanism 9, the outer wheel of the second inner ratchet mechanism 9 rotates synchronously, thereby driving the transmission gear 6 coaxially arranged therewith to rotate synchronously to change the rotation angle of the outer gear 32.

[0047] In this embodiment, the first inner ratchet mechanism 8 and the second inner ratchet mechanism 9 are both composed of an inner wheel, an outer wheel and a ratchet structure, and the ratchet only allows the inner wheel and the outer wheel to rotate relative to each other in one direction, thereby realizing one-way transmission. This design utilizes the one-way engagement characteristics of the ratchet, so that power can only be transmitted in a predetermined direction and reverse transmission is prevented, thereby ensuring the stable operation of the mechanism and the realization of specific functions.

[0048] Replay Figure 1 and Figure 2 On the other hand, a movable plate 13 is slidingly provided on the side wall of the buried box 1, and a wire group connector 131 is installed on the movable plate 13. A terminal block 21 is fixed on the side wall of the distribution cabinet body 2. The wire group connector 131 is plugged into the terminal block 21. The wire group connector 131 connects the electrical signal of the distribution cabinet body 2 to other devices through the underground pre-buried signal line.

[0049] During normal operation, the wire group connector 131 on the movable plate 13 is plugged into the terminal socket 21 of the distribution cabinet body 2, so that the current produced by the distribution cabinet body 2 can flow out to the outside. When the distribution cabinet body 2 needs to be inspected and maintained, the movable plate 13 can be controlled to move horizontally to separate the wire group connector 131 on the movable plate 13 from the terminal socket 21 of the distribution cabinet body 2, thereby reducing the obstruction to the displacement of the sliding plate 3 in the vertical direction and improving stability.

[0050] Specifically, a second transmission assembly 10 is arranged between the cover plate 4 and the movable plate 13, and the second transmission assembly 10 includes a second pulley transmission mechanism 101 and a second crank-connecting rod mechanism 102. The turntable of the second crank-connecting rod mechanism 102 is rotatably supported on the side wall of the buried box 1, and the second pulley transmission mechanism 101 is connected between the rotating shaft of the cover plate 4 and the turntable of the second crank-connecting rod mechanism 102. The connecting rod of the second crank-connecting rod mechanism 102 is hinged to the movable plate 13.

[0051] Correspondingly, by operating the cover plate 4, the movement of its rotating shaft is transmitted to the turntable of the second crank-connecting rod mechanism 102 through the second pulley transmission mechanism 101. The turntable of the second crank-connecting rod mechanism 102 rotates, driving the connecting rod hinged thereto to move, and then driving the movable plate 13 to move horizontally. The wire group connector 131 on the movable plate 13 is separated from the terminal socket 21 of the distribution cabinet body 2. This process reduces the displacement obstacle of the sliding plate 3 in the vertical direction, improves the stability of the entire system, and also facilitates the inspection and maintenance of the distribution cabinet body 2.

[0052] Furthermore, a guide rod 132 is fixed to the side wall of the movable plate 13, and a guide groove 14 is opened on the side wall of the buried box 1. The guide rod 132 is slidably arranged in the guide groove 14 along the horizontal direction, which can guide the precise movement of the movable plate 13 and limit its displacement in other directions, thereby ensuring the smooth separation of the wire group connector 131 and the terminal block 21.

[0053] On the other hand, a groove 41 is formed on the top of the cover plate 4 , a gripping portion 411 is built inside the groove 41 , a sealing gasket is fixed to the side wall of the cover plate 4 , and the sealing gasket abuts against the side wall of the top opening of the buried box 1 .

[0054] Therefore, a groove 41 is provided at the top of the cover plate 4, and a gripping portion 411 is built inside the groove 41. This design facilitates the operator to easily open or close the cover plate 4 through the gripping portion 411, thereby improving the convenience of operation. At the same time, a sealing gasket (not shown in the figure) is fixed to the side wall of the cover plate 4, and the sealing gasket abuts against the side wall of the top opening of the buried box 1, thereby ensuring the sealing inside the buried box 1 when the cover plate 4 is closed, effectively preventing external impurities such as moisture and dust from entering the buried box 1, protecting the distribution cabinet body 2 from environmental factors, extending the service life of the equipment, and ensuring the safe operation of the power system.

[0055] The implementation principle of an integrated transformer distribution cabinet in the embodiment of the present application is: The sliding plate 3 and driving assembly 5 inside the buried box 1 allow the distribution cabinet body 2 to move in the vertical direction through the driving assembly 5 when maintenance or operation is required, so that the distribution cabinet body 2 rises above the ground to facilitate operation by the staff. When not in use, the distribution cabinet body 2 can be lowered below the ground, and the cover plate 4 seals the opening of the buried box 1 to keep the ground flat and safe, thereby pre-burying the main part of the integrated transformer distribution cabinet The buried box 1 is buried below the ground, effectively solving the problem of tight space resources in the petrochemical production field.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
