Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a transformer auxiliary maintenance device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. In electrical equipment and wireless circuits, it is commonly used for voltage step-up and step-down, impedance matching, and safety isolation. In generators, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electromotive force can be induced in the coil. Generally, when transformers are used outdoors, they need to be installed on utility poles, which makes it inconvenient to inspect and maintain the transformer when a fault occurs.

[0003] According to a transformer maintenance and repair management device (Announcement No.: CN217984244U) disclosed in the above application, the device, through the setting of a support frame, a third fixing bolt, a fourth nut, and a guardrail, facilitates maintenance personnel to inspect and repair the transformer. In use, the support frame is placed on both sides of the surface of the support plate and then locked with the third fixing bolt and the fourth nut. The support frame allows maintenance personnel to stand comfortably. Then, the guardrails are installed on both sides of the support frame to increase the safety of maintenance personnel.

[0004] However, in actual use, the transformers are usually installed at a high height. Workers need to use ladders to connect with the transformer mounting base and then climb over the fence. Climbing over the fence at a high position is particularly dangerous, and workers lack sufficient safety guarantees, which can easily lead to safety hazards. In view of this, we propose a transformer auxiliary maintenance device. Summary of the Invention

[0005] The purpose of this invention is to provide a transformer auxiliary maintenance device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transformer auxiliary maintenance device, including a base, a fence fixedly installed on the upper surface of the base, a steel frame fixedly installed on the lower surface of the base, locking frames provided on the upper and lower sides of the steel frame, and a support component provided between the base and the fence; The support assembly includes a support column, which is fixedly installed between the base and the fence. An electronic lock is fixedly installed on the inner wall of the support column. A square plate is slidably installed on the bottom inner wall of the support column. A large spring is fixedly connected between the bottom surface of the square plate and the support column. A rotating shaft is rotatably installed on the side wall of the square plate. A movable door is fixedly connected to the end of the rotating shaft. A limit hole is opened on the inner wall of the rotating shaft near the square plate. A through hole is opened on the inner wall of the square plate. A square rod is fixedly installed on the inner wall of the support column. A limit block is slidably installed on the outer wall of the square rod. A guide hole is opened on the inner wall of the limit block. A small spring is fixedly connected between the end of the square rod and the inner wall of the guide hole.

[0007] Preferably, the number of the support pillars is set in two sets, and the two sets of support pillars are mirrored on both sides of the vertical central axis of the base to facilitate the opening and closing of the movable door.

[0008] Preferably, the outer walls on both sides of the movable door are provided with lock holes adapted to the electronic lock latch tongue, and the electronic lock latch is remotely controlled via Bluetooth or wireless communication equipment, so that maintenance personnel can control the electronic lock latch to release the movable door from the ground away from high altitudes.

[0009] Preferably, the limiting hole and the through hole are the same size, and the limiting hole is adapted to the limiting block. At the same time, the bottom surface of the limiting block is set as an inclined surface, so that when the square plate slides upward along the inner wall of the column, it will push the limiting block to move away from the rotating axis.

[0010] Preferably, the square rod is adapted to the guide hole, so that the limiting block can only slide in the horizontal direction.

[0011] Preferably, the bottom of the base is provided with a stabilizing component, the stabilizing component includes an inclined groove, the inclined groove is formed on the top surface of the base near the movable door, an L-shaped support frame is fixedly installed on the lower surface of the base, and an embedded groove is formed on the top side wall of the movable door.

[0012] Preferably, the number of embedded grooves is set in multiple sets, and the multiple sets of embedded grooves are evenly distributed in a linear array on the side of the movable door. The inner surface of the embedded groove is provided with a rubber pad, and the width of the embedded groove is adapted to the width of the ladder frame, thereby further improving the connection stability between the ladder used by maintenance personnel and the movable door.

[0013] Compared with the prior art, the present invention provides a transformer auxiliary maintenance device, which has the following beneficial effects: 1. This transformer auxiliary maintenance device, equipped with a support assembly, allows maintenance personnel to attach a ladder to an open movable door during maintenance. As the personnel climb upwards, the weight of the ladder and the movable door causes the square plate to slide downwards along the inner wall of the support column, compressing the large spring until the limiting block is aligned with the through hole and the limiting hole. At this point, the limiting block, under the elastic force of the small spring, passes through the through hole and enters the limiting hole. The rotating shaft cannot rotate at this point. Due to the weight of the externally erected ladder restricting the movable door, the limiting block remains inserted in the limiting hole, and the movable door remains in a downward position, facilitating maintenance personnel to enter the fenced area to maintain the transformer.

[0014] 2. This transformer auxiliary maintenance device, by incorporating stabilizing components and using inclined slots and L-shaped support frames, increases the contact area between the base and the movable door, ensuring that the movable door provides more stable support for the ladder erected by maintenance personnel. This further improves the connection stability between the ladder used by maintenance personnel and the movable door, ensuring the safety of maintenance personnel when maintaining the transformer.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a transformer auxiliary maintenance device, including a base 1, a fence 2 fixedly installed on the upper surface of the base 1, a steel frame 3 fixedly installed on the lower surface of the base 1, locking frames 4 provided on the upper and lower sides of the steel frame 3, and a support component 5 provided between the base 1 and the fence 2. The support component 5 includes a column 51, an electronic lock 52, a square plate 53, a large spring 54, a rotating shaft 55, a limiting hole 56, a through hole 57, a square rod 58, a limiting block 59, a guide hole 510, and a small spring 511.

[0018] In one embodiment of this utility model, a support column 51 is fixedly installed between a base 1 and a fence 2. An electronic lock 52 is fixedly installed on the inner wall of the support column 51. A square plate 53 is slidably installed on the bottom inner wall of the support column 51. A large spring 54 is fixedly connected between the bottom surface of the square plate 53 and the support column 51. A rotating shaft 55 is rotatably installed on the side wall of the square plate 53. A movable door 7 is fixedly connected to the end of the rotating shaft 55. A limiting hole 56 is opened on the inner wall of the rotating shaft 55 near the square plate 53. A through hole 57 is opened on the inner wall of the square plate 53. A square rod 58 is fixedly installed on the inner wall of the support column 51. A limiting block 59 is slidably installed on the outer wall of the square rod 58. A guide hole 510 is opened on the inner wall of the limiting block 59. A small spring 511 is fixedly connected between the end of the square rod 58 and the inner wall of the guide hole 510.

[0019] Furthermore, the number of steel frames 3 is set in two sets, with the two sets of steel frames 3 arranged at intervals below the base 1, and the locking frame 4 between the ends of the two sets of steel frames 3 includes a clamp to facilitate the installation of the equipment on the outer surface of the electrical poles used for laying electrical equipment, thereby facilitating the installation of the entire device.

[0020] Meanwhile, two sets of support pillars 51 are provided, and the two sets of support pillars 51 are mirrored on both sides of the vertical central axis of the base 1 to facilitate the opening and closing of the movable door 7. In addition, the movable door 7 can rotate in the gap between the two sets of support pillars 51 with the pivot 55 as the rotation center. Furthermore, the outer walls on the left and right sides of the movable door 7 are provided with lock holes that are compatible with the latch of the electronic lock 52. The electronic lock 52 can be remotely controlled via Bluetooth or wireless communication devices. Maintenance personnel can first control the electronic lock 52 to release the lock on the movable door 7 from the ground away from the height, so that maintenance personnel can use a ladder to flip the movable door 7 outward. At the same time, the limiting hole 56 and the through hole 57 are the same size, and the limiting hole 56 is compatible with the limiting block 59. The bottom surface of the limiting block 59 is set as an inclined surface, so that when the square plate 53 slides upward along the inner wall of the support pillar 51, it will push the limiting block 59 to move away from the pivot 55, thereby releasing the limiting block 59 from limiting the square plate 53 and the pivot 55.

[0021] In addition, there are two sets of large springs 54, which are mirror images of each other on the bottom front and rear sides of the square plate 53. In the initial state, the large springs 54 have an upward tendency to push the square plate 53. At the same time, the square rod 58 is adapted to the guide hole 510, so that the limiting block 59 can only slide in the horizontal direction. When the square plate 53 moves downward under the action of the rotating shaft 55 and the movable door 7, the limiting block 59 is on the same straight line as the through hole 57 and the limiting hole 56. Under the elastic force of the small spring 511, the limiting block 59 passes through the through hole 57 and enters the limiting hole 56. At this time, the rotating shaft 55 cannot rotate. Due to the weight of the external ladder restricting the movable door 7, the limiting block 59 is always inserted in the limiting hole 56. The movable door 7 will remain in a downward state to facilitate maintenance personnel to enter the area of ​​the fence 2 to maintain the transformer.

[0022] In an embodiment of this utility model, a stabilizing component 6 is provided at the bottom of the base 1. The stabilizing component 6 includes a sloping groove 61, which is opened on the top surface of the base 1 near the movable door 7. An L-shaped support frame 62 is fixedly installed on the lower surface of the base 1, and an embedded groove 63 is opened on the top side wall of the movable door 7.

[0023] Specifically, the inclined groove 61 allows the movable door 7 to remain tilted after it is opened, and it increases the contact area between the base 1 and the movable door 7, ensuring that the movable door 7 can provide more stable support for the ladder set up by maintenance personnel. At the same time, there are multiple sets of embedded grooves 63, which are evenly distributed in a linear array on the side of the movable door 7. The inner surface of the embedded groove 63 is provided with a rubber pad, and the width of the embedded groove 63 is adapted to the width of the ladder frame, thereby further improving the connection stability between the ladder used by maintenance personnel and the movable door 7, and ensuring the safety of maintenance personnel when maintaining the transformer.

[0024] In this invention, during use, the operator first opens the electronic latch 52 remotely to release the lock on the movable door 7. Then, the operator uses a ladder to flip the movable door 7 outward, causing it to deflect outward around the pivot 55. After the movable door 7 is open, the operator aligns the ladder with the inner groove 63 and inserts it. At this point, the top of the ladder is secured to the movable door 7. As the operator climbs upward, due to the weight of the ladder and the movable door 7, the square plate 53 slides down along the inner wall of the support column 51 to compress the large spring 54 until the limiting block 59 engages with the through hole 57 and the limiting hole. When 56 are on the same straight line, the limiting block 59 passes through the through hole 57 and enters the limiting hole 56 under the elastic force of the small spring 511. At this time, the rotating shaft 55 cannot rotate. Due to the weight of the externally erected ladder restricting the movable door 7, the limiting block 59 is always inserted in the limiting hole 56, and the movable door 7 will remain in a hanging state to facilitate maintenance personnel to enter the area of ​​the fence 2 to maintain the transformer. At the same time, the bottom of the flipped movable door 7 will be supported by the inclined groove 61 and the L-shaped support frame 62 to maintain the stability of the movable door 7 in the flipped open state and ensure the safety of maintenance personnel.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
