Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and specifically to a power transformer. Background Art

[0002] A power transformer is a static electrical device used to convert an alternating voltage (current) of a certain value into another or several alternating voltages (currents) of different values with the same frequency. It is one of the important devices for power transmission. The economic value of power transformers is relatively high, which has led to some theft phenomena in society. Therefore, in addition to optimizing the structural performance of power transformers themselves, the anti-theft installation structure of power transformers also needs to be improved synchronously in related research topics.

[0003] In the prior art, the patent document with the application number CN202210494407.9 discloses that "through the setting of the anti-theft locking component, during the installation of the transformer on the fixed seat, the rotation of the transmission shaft drives the gear to rotate, and the end of the ratchet on one side is engaged into the tooth groove of the gear under the action of the spring, realizing the braking of the reverse rotation of the transmission shaft, thereby realizing the locking of the clamping block to the transformer for clamping and fixing. Moreover, the ratchet of the unlocking structure is located below the transformer, and the user can only disassemble the transformer by controlling the electric push rod to work. This structure can effectively avoid the occurrence of transformer theft problems and has good anti-theft functions."

[0004] However, from the perspective of actual operation, the locking structure overly relies on electronic components as the opening and closing power, which is prone to forced opening after power failure. Secondly, during long-term use, the locking structure exposed to the use environment also has a high probability of structural failure due to corrosion. Summary of the Invention

The first single-inclined surface pressing plate can press and transmit the assembly formed by the second single-inclined surface pressing plate, the I-shaped shaft and the double-inclined surface pressing plate under the pressing of the spiral meshing of the threaded rod and the internally threaded sleeve.

As the support frame is separated from the mounting base, the L-shaped shaft will also be separated from the pressure sensor as the supporting curved plate is reset. At this time, the pressure data returns to zero. At the same time, the controller component transmits the pressure data change phenomenon to the control center at the back end. At the same time, the alarm inside the controller component starts to alarm, thereby increasing the psychological pressure of the thief, and there is a certain probability that the thief will give up and reduce the loss.

Detailed implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-10 , a power transformer, including a mounting base 1 and a transformer body 2. The front end of the mounting base 1 is a semi-open structure, and an auxiliary partition 6 is fixedly nested in the middle of the mounting base 1. The bottom of the support frame 3 is sleeved in the top of the mounting base 1 through the semi-open structure and is in contact with the top of the auxiliary partition 6. And the front end structure of the support frame 3 is connected with a first sealing cover plate 4 that can cover and seal the semi-open structure, and the mounting base 1 is fixed on the top of the support frame 3; A chute 11 communicating with the space of the semi-open structure is opened at the top of the mounting base 1. The chute 11 can be clamped with the middle structure of the support frame 3, and a sealing strip 12 that can fill and seal the clamping gap between the chute 11 and the support frame 3 is fixedly nested on the inner side of the top of the chute 11, thereby improving the structural sealing effect of the assembly formed by the mounting base 1 and the support frame 3; A positioning sleeve 5 is fixedly mounted on the bottom surface of the support frame 3. An adjusting rod 10 aligned with the positioning sleeve 5 is mounted on the inner wall of the top of the mounting base 1. A first transmission member 7 and a second transmission member 8 are respectively sleeved inside the bottom of the mounting base 1 and the middle of the auxiliary partition 6. A third transmission member 9 is sleeved inside the top of the mounting base 1. The first transmission member 7, the second transmission member 8, the third transmission member 9, and the adjusting rod 10 can be successively pressed and transmitted, and the adjusting rod 10 can be clamped with the positioning sleeve 5 under the successive pressing and transmission of the first transmission member 7, the second transmission member 8, and the third transmission member 9 to hermetically lock the support frame 3 and the mounting base 1; The first transmission member 7 includes a first single inclined surface pressing plate 71, a threaded rod 72, an internal thread sleeve 73, and a limit ring 74. The internal thread sleeve 73 is fixedly sleeved inside one side of the mounting base 1. The two ends of the threaded rod 72 are respectively threadedly connected to the inner side of one end of the internal thread sleeve 73 and clamped with the inner side of the limit ring 74. One end of the limit ring 74 is fixedly connected to the surface of one side of the first single inclined surface pressing plate 71, and the end surface of the end of the threaded rod 72 sleeved with the limit ring 74 is in contact with the side surface of one side of the first single inclined surface pressing plate 71. The end surface of the other end of the internal thread sleeve 73 is coplanar with the side surface of one side of the mounting base 1 to avoid structural interference. A guide rail 75 fixed on the inner wall of the bottom of the mounting base 1 is clamped at the bottom of the first single inclined surface pressing plate 71. An internal hexagonal groove is provided in the end of the threaded rod 72 sleeved inside the internal thread sleeve 73 to facilitate subsequent force application and torsion; The second transmission member 8 includes an I-shaped shaft 81, a second single inclined surface pressing plate 82, a first spring 83, and a double inclined surface pressing plate 84. The middle of the I-shaped shaft 81 is clamped inside the middle of the auxiliary partition 6. The middle inner side of the double inclined surface pressing plate 84 and the middle inner side of the second single inclined surface pressing plate 82 are respectively fixedly nested on the upper end and the lower end of the top of the I-shaped shaft 81. The two ends of the first spring 83 are respectively fixed on the surface of the double inclined surface pressing plate 84 and the top surface of the auxiliary partition 6. The first single inclined surface pressing plate 71 can press and transmit the assembly formed by the second single inclined surface pressing plate 82, the I-shaped shaft 81, and the double inclined surface pressing plate 84 under the pressing of the threaded rod 72 and the internal thread sleeve 73 in spiral engagement; The third transmission member 9 includes a slide rail 91. Pressing slide plates 92 are clamped at both ends of the slide rail 91, and a second spring 94 is mounted between the two pressing slide plates 92. Transmission inclined pressing surfaces 95 and transition top plates 93 are respectively arranged on both sides of the pressing slide plates 92; The components of the transition top plate 93, the top pressure slide plate 92 and the transmission inclined pressure surface 95 can be driven by the double inclined surface pressure plate 84, so that the transmission inclined pressure surface 95 presses down the adjustment rod 10 and makes the adjustment rod 10 clamp and lock the positioning sleeve 5. The adjustment rod 10 includes a supporting curved plate 101, a T-shaped shaft 102 and a third spring 103. The top of the supporting curved plate 101 is fixed to the inner wall of the top of the mounting base 1, and the middle part of the T-shaped shaft 102 is clamped on the bottom structure of the supporting curved plate 101. The two ends of the third spring 103 are respectively fixed on the surface of one end of the T-shaped shaft 102 and the surface of the bottom of the supporting curved plate 101. One end of the T-shaped shaft 102 is a spherical structure, which is convenient for subsequent top pressure, avoids structural scratches, and improves the service life of the structure.

[0021] When in use, the number of positioning sleeves 5 is the same as the number of adjusting rods 10 and four are provided, respectively distributed on the four corners at the bottom of the support frame 3 and the four corners at the top inner wall of the mounting base 1. The mounting base 1 is first installed at the specified position, including pre-embedded concrete or fixed with screws, and then the support frame 3 and the mounting base 1 are assembled. The semi-open structure and the slide groove 11 of the mounting base 1 provide a clearance hole space. The auxiliary partition plate 6 inside the mounting base 1 is in synchronous contact with the support frame 3 and provides stable support for the support frame 3. After the support frame 3 and the mounting base 1 are completely assembled, the first sealing cover plate 4 covers and closes the semi-open structure of the mounting base 1, thereby making the internal space of the mounting base 1 in a relatively closed space, and then the various structures arranged inside the mounting base 1 are protected against corrosion; Next, a specific wrench is used to engage with the hexagonal groove in the end of the threaded rod 72 and twist the threaded rod 72, so that the threaded rod 72 is spirally displaced inside the internal threaded sleeve 73 and simultaneously presses the first single-inclined surface pressing plate 71, so that the first single-inclined surface pressing plate 71 produces a linear displacement, and the guide rail 75 provides guidance and auxiliary support; During the movement, the threaded rod 72 will synchronously press against the second single-inclined surface pressing plate 82, thereby causing the assembly formed by the second single-inclined surface pressing plate 82, the first single-inclined surface pressing plate 71, and the double-inclined surface pressing plate 84 to move upward synchronously to press against the transmission transition top plate 93. Moreover, the double-inclined surface structure of the double-inclined surface pressing plate 84 can synchronously press and drive the two transition top plates 93, and then the two transition top plates 93 respectively drive their corresponding pressing slide plates 92 to move away from each other. Similarly, under further pressing and driving, the driving inclined pressing surfaces 95 of the two pressing slide plates 92 respectively press against their corresponding two supporting curved plates 101 synchronously until the adjusting rod 10 is inserted into the corresponding positioning sleeve 5, thereby realizing the convenient assembly of the mounting base 1, the transformer body 2, and the support frame 3. The specific wrench is used under real name and does not circulate in the market. Secondly, the size of the internal hexagonal groove can also be adjusted in the way of one transformer per box, thereby increasing the difficulty of unlocking the adjusting rod 10 and the positioning sleeve 5. Moreover, the pure mechanical structure of the limit locking makes the overall device have excellent impact resistance.

[0022] Please refer to Figures 1-10 , a threaded hole concentric with the internal thread sleeve 73 is opened on the side surface of one side of the mounting base 1, and a second sealing cover plate 14 is threadedly connected in the threaded hole. A plurality of sector-shaped grooves arranged along its circumferential direction are opened on the side surface of one side of the second sealing cover plate 14, and the side surface of one side of the second sealing cover plate 14 is coplanar with the side surface of one side of the mounting base 1; The number of the positioning sleeves 5 and the adjusting rods 10 is less than two, and the positioning sleeves 5 and the adjusting rods 10 are respectively installed on the bottom surface of the auxiliary partition plate 6 and the top inner wall of the mounting base 1 in an inclined manner.

[0023] A sealing ring 13 is nested on the rear end surface of the first sealing cover plate 4. The sealing ring 13 can seal and fill the connection part after the semi-open structure of the first sealing cover plate 4 and the mounting base 1 is sleeved, thereby ensuring the sealing effect of the assembly formed after the mounting base 1 and the support frame 3 are locked and assembled, and then providing sealing and anti-corrosion protection for the various structures sleeved inside the mounting base 1.

[0024] During use, considering the anti-corrosion protection of the threaded rod 72, the second sealing cover plate 14 is used to perform secondary sealing assembly with the mounting base 1 through the threaded hole opened on the mounting base 1 to provide anti-corrosion closed protection for the threaded rod 72; Considering the sealing effect of the first sealing cover plate 4 on the open structure of the mounting base 1, on the basis of the transmission locking assembly of the positioning sleeve 5 and the adjusting rod 10, during the assembly process of the positioning sleeve 5 and the adjusting rod 10 in an inclined state, in addition to decomposing the displacement force for horizontal movement, the force exerted by the adjusting rod 10 on the negative direction of the inclined sleeve of the positioning sleeve 5 can also apply a vertically downward traction force to the sleeve of the open structure of the first sealing cover plate 4 on the mounting base 1, increasing the connection strength between the first sealing cover plate 4 and the open structure of the mounting base 1. Cooperating with the sealing ring 13, it can fully improve the combined sealing effect of the mounting base 1 and the first sealing cover plate 4, and fully ensure the use effect of sealing and anti-corrosion for each structure inside the mounting base 1.

[0025] Please refer to Figure 9 、 Figures 11-12 , a pressure sensor 16 and an L-shaped shaft 17 are arranged inside the middle part of the support curved plate 101. One end of the L-shaped shaft 17 is fixed to the end surface of one end of the T-shaped shaft 102, and the other end of the L-shaped shaft 17 can be in contact with the sensing surface voltage of the pressure sensor 16 fixed on the inner wall of the middle part of the support curved plate 101. The pressure sensor 16 is electrically connected to a controller component 15 through a wire. The controller component 15 includes a housing. Inside the housing, a processor, an alarm, a wireless transmission module and a battery module are sleeved, and the housing is fixed on the inner wall of the mounting base 1.

[0026] During use, considering the theft problem of industry insiders who can access a specific wrench, it is solved by further setting the controller component 15, the pressure sensor 16 and the L-shaped shaft 17 in cooperation, as follows: During the sleeving process of the adjusting rod 10 and the positioning sleeve 5, the L-shaped shaft 17 that moves synchronously with the corresponding support curved plate 101 will move closer to the pressure sensor 16. After the sleeving and locking of the adjusting rod 10 and the positioning sleeve 5 are completed, the L-shaped shaft 17 will also apply a certain pressure to the pressure sensor 16, and the pressure sensor 16 will generate pressure data and transmit the pressure data to the controller component 15; When subsequent industry insiders who can access a specific wrench steal, as the support frame 3 is separated from the mounting base 1, the L-shaped shaft 17 will also be separated from the pressure sensor 16 as the support curved plate 101 resets. At this time, the pressure data returns to zero. At the same time, the controller component 15 transmits the phenomenon of pressure data change to the control center at the back end. At the same time, the alarm inside the controller component 15 starts to alarm, increasing the psychological pressure of the thief and having a certain probability of increasing the chance of giving up and reducing the loss.
