Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a power transformer. Background Technology

[0002] A power transformer is a static electrical device used to convert a given AC voltage (current) into one or more different voltages (currents) at the same frequency. It is a crucial component in power transmission. The high economic value of power transformers has led to theft. Therefore, research in this field requires not only optimizing the structural performance of power transformers themselves but also simultaneously improving their anti-theft installation structures.

[0003] In the prior art, patent application number CN202210494407.9 discloses that "through the setting of the anti-theft locking component, during the installation of the transformer on the fixed base, the rotation of the drive shaft drives the gear to rotate, and the pawl on one side engages with the gear tooth groove under the action of the spring, realizing the braking of the drive shaft to reverse, thereby realizing the locking of the clamping block to clamp and fix the transformer. Moreover, the pawl of the unlocking structure is located below the transformer, and the user can only disassemble the transformer by controlling the electric push rod. This structure can effectively prevent the theft of the transformer and has a good anti-theft function."

[0004] However, from a practical point of view, the locking structure relies too much on electronic components as the power to open and close, which makes it easy to be forcibly opened after the power is cut off. Secondly, during long-term use, the locking structure exposed to the use environment is also very likely to suffer structural failure due to corrosion. Summary of the Invention

The two ends of the first spring are respectively fixed on the surface of the double-inclined pressure plate and the top surface of the auxiliary partition.

[0013] The first single-inclined pressure plate can perform top pressure transmission on the assembly formed by the second single-inclined pressure plate, the I-shaped shaft, and the double-inclined pressure plate under the top pressure of the threaded rod and the internal threaded sleeve in helical engagement.

[0014] Preferably, the third transmission component includes a slide rail, both ends of which are engaged with a top-pressing slide plate, and a second spring is installed between the two top-pressing slide plates. The two sides of the top-pressing slide plate are respectively provided with a transmission inclined pressing surface and a transition top plate.

[0015] The components of the transition top plate, the top pressing slide plate, and the transmission inclined pressing surface can be pressed and driven by the double inclined pressing plate, so that the transmission inclined pressing surface presses down on the adjusting rod and the adjusting rod engages with the positioning sleeve.

[0016] The adjusting rod includes a support curved plate, a T-shaped shaft, and a third spring. The top of the support curved plate is fixed to the inner wall of the top of the mounting base.

[0021] The pressure sensor is electrically connected to a controller component via wires. The controller component includes a housing, which houses a processor, an alarm, a wireless transmission module, and a battery module. The housing is fixed to the inner wall of the mounting base.

[0022] The present invention has the following beneficial effects:

[0023] 1. The present invention forms a combined transmission mechanism by setting a first transmission component, a second transmission component, and a third transmission component. After being combined with the mounting base, an auxiliary partition, a support frame, multiple positioning sleeves set on the support frame, and multiple adjusting rods set inside the mounting base, the combined transmission mechanism can synchronously drive multiple adjusting rods to lock one-to-one with the corresponding number of positioning sleeves, ensuring the locking strength while being flexible and convenient in the overall locking process. Moreover, the purely mechanical limit locking structure makes the overall device highly impact resistant.

[0024] 2. The present invention, through the linkage of the first sealing cover plate, sealing ring, sliding groove and sealing strip, in the assembly process of the mounting base and support frame, thereby making the assembly of the mounting base and support frame in a relatively closed state, thereby providing sealing and corrosion protection for the various mechanical components inside the mounting base.

[0025] 3. This invention comprises a remote control device consisting of a controller component, a pressure sensor, and an L-shaped shaft. When used in conjunction with the assembly of the adjusting rod and the positioning sleeve, it addresses the issue of theft by industry personnel who have access to a specific wrench. As the support frame separates from the mounting base, the L-shaped shaft also separates from the pressure sensor along with the reset of the support plate. At this point, the pressure data returns to zero. Simultaneously, the controller component transmits the pressure data change to the control center at the back end. At the same time, the alarm inside the controller component sounds, increasing the psychological pressure on the thief and potentially increasing their chances of abandoning the theft, thus reducing losses.

[0039] 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.

[0040] Please see Figures 1-10 A power transformer includes 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 fitted into the top of the mounting base 1 through the semi-open structure and is in close contact with the top of the auxiliary partition 6. The front end of the support frame 3 is connected to a first sealing cover 4 that can cover and seal the semi-open structure. The mounting base 1 is fixed to the top of the support frame 3.

[0041] The top of the mounting base 1 is provided with a groove 11 that communicates with the semi-open structural space. The groove 11 can be engaged with the middle structure of the support frame 3. A sealing strip 12 is fixedly nested on the inner side of the top of the groove 11 to fill and seal the gap between the groove 11 and the support frame 3, thereby improving the structural sealing effect of the assembly formed by the mounting base 1 and the support frame 3.

[0042] A positioning sleeve 5 is fixed to the bottom surface of the support frame 3. An adjusting rod 10 aligned with the positioning sleeve 5 is installed on the inner wall of the top of the mounting base 1. A first transmission component 7 and a second transmission component 8 are respectively installed in the bottom of the mounting base 1 and the middle of the auxiliary partition 6. A third transmission component 9 is installed in the top of the mounting base 1. The first transmission component 7, the second transmission component 8, the third transmission component 9, and the adjusting rod 10 can be sequentially pressed and transmitted. The adjusting rod 10 can be engaged with the positioning sleeve 5 under the sequential pressing and transmission of the first transmission component 7, the second transmission component 8, and the third transmission component 9, thereby sealing and locking the support frame 3 and the mounting base 1.

[0043] The first transmission component 7 includes a first single-inclined surface pressure plate 71, a threaded rod 72, an internal threaded sleeve 73, and a limiting ring 74. The internal threaded sleeve 73 is fixedly sleeved inside one side of the mounting base 1. The two ends of the threaded rod 72 are respectively threaded to the inner side of one end of the internal threaded sleeve 73 and snapped into the inner side of the limiting ring 74. One end of the limiting ring 74 is fixedly connected to the surface of one side of the first single-inclined surface pressure plate 71, and the end face of the threaded rod 72 and the limiting ring 74 are fitted and connected to the side of one side of the first single-inclined surface pressure plate 71. The end face of the other end of the internal threaded sleeve 73 is coplanar with the side of one side of the mounting base 1 to avoid structural interference. The bottom of the first single-inclined surface pressure plate 71 is snapped into a guide rail 75 fixed on the inner wall of the bottom of the mounting base 1. The end of the threaded rod 72 fitted inside the internal threaded sleeve 73 has an internal hexagonal groove to facilitate subsequent force application and torsion.

[0044] The second transmission component 8 includes an I-shaped shaft 81, a second single-inclined pressure plate 82, a first spring 83, and a double-inclined pressure plate 84. The middle part of the I-shaped shaft 81 is engaged with the inner side of the middle part of the auxiliary partition 6. The inner side of the middle part of the double-inclined pressure plate 84 and the inner side of the middle part of the second single-inclined pressure plate 82 are respectively fixedly nested on the top end of the I-shaped shaft 81 and the bottom end of the I-shaped shaft 81. The two ends of the first spring 83 are respectively fixed on the surface of the double-inclined pressure plate 84 and the top surface of the auxiliary partition 6. Under the top pressure of the threaded rod 72 and the internal threaded sleeve 73, the first single-inclined pressure plate 81 can perform top pressure transmission on the assembly formed by the second single-inclined pressure plate 82, the I-shaped shaft 81, and the double-inclined pressure plate 84.

[0045] The third transmission component 9 includes a slide rail 91, with top pressure slide plates 92 engaged at both ends of the slide rail 91, and a second spring 94 installed between the two top pressure slide plates 92. The top pressure slide plates 92 are respectively provided with a transmission inclined pressure surface 95 and a transition top plate 93 fixed on both sides.

[0046] 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 pressure plate 84, causing the transmission inclined pressure surface 95 to press down on the adjusting rod 10 and lock the adjusting rod 10 into the positioning sleeve 5. The adjusting rod 10 includes a support curved plate 101, a T-shaped shaft 102, and a third spring 103. The top of the support curved plate 101 is fixed to the inner wall of the top of the mounting base 1. The middle part of the T-shaped shaft 102 is engaged with the bottom structure of the support curved plate 101. The two ends of the third spring 103 are respectively fixed to the surface of one end of the T-shaped shaft 102 and the surface of the bottom of the support curved plate 101. One end of the T-shaped shaft 102 has a spherical structure, which facilitates subsequent top pressure, avoids structural scratches, and improves the service life of the structure.

[0047] In use, the number of positioning sleeves 5 is the same as the number of adjusting rods 10, and four of them are set. They are distributed on the four corners of the bottom of the support frame 3 and the four corners of the top inner wall of the mounting base 1. The mounting base 1 is first installed in the designated position, either by pre-embedding in concrete or by fixing with screws. Then the support frame 3 and the mounting base 1 are fitted together. The semi-open structure and the sliding groove 11 of the mounting base 1 provide clearance hole space. The auxiliary partition 6 inside the mounting base 1 contacts the support frame 3 synchronously and provides stable support for the support frame 3. After the support frame 3 and the mounting base 1 are completely fitted together, the first sealing cover 4 covers and seals the semi-open structure of the mounting base 1, thereby making the internal space of the mounting base 1 a relatively closed space, and then providing anti-corrosion protection for the various structures set inside the mounting base 1.

[0048] Next, a specific wrench is used to engage with the internal hexagonal groove at the end of the threaded rod 72 and the threaded rod 72 is turned, thereby causing the threaded rod 72 to move spirally inside the internal threaded sleeve 73 and simultaneously press against the first single-inclined surface pressure plate 71, causing the first single-inclined surface pressure plate 71 to move linearly, and the guide rail 75 provides guidance and auxiliary support.

[0049] During the movement, the threaded rod 72 will synchronously press against the second single-inclined surface pressure plate 82, thereby causing the assembly formed by the second single-inclined surface pressure plate 82, the first single-inclined surface pressure plate 71, and the double-inclined surface pressure plate 84 to move upward synchronously to press against the transmission transition plate 93. Furthermore, the double-inclined surface pressure plate 84's double-inclined surface structure allows it to synchronously press against the two transition plates 93, causing each of the two transition plates 93 to drive its corresponding pressing slide plate 92 to move out of phase. Similarly, under further pressing, the two pressing slide plates 92... The transmission inclined pressure surface 95 synchronously presses against the two corresponding support curved plates 101 until the adjusting rod 10 is inserted into the corresponding positioning sleeve 5, thereby realizing the convenient assembly of the mounting base 1, transformer body 2, and support frame 3. The specific wrench is used under real name and is not circulated in the market. Secondly, the size of the internal hexagonal slot can also be adjusted in a one-box-one-change manner, thereby increasing the difficulty of unlocking the adjusting rod 10 and the positioning sleeve 5. Moreover, the limit locking of the pure mechanical structure makes the overall device have excellent impact resistance.

[0050] Please see Figures 1-10 The mounting base 1 has a threaded hole on one side that is concentric with the internal threaded sleeve 73. The threaded hole is connected to the second sealing cover plate 14. The second sealing cover plate 14 has several fan-shaped grooves arranged along its circumference on one side, and the side of the second sealing cover plate 14 is coplanar with the side of the mounting base 1.

[0051] The number of positioning sleeves 5 and adjusting rods 10 is less than two, and the positioning sleeves 5 and adjusting rods 10 are installed at an angle on the bottom surface of the auxiliary partition 6 and the top inner wall of the mounting base 1, respectively.

[0052] The rear end surface of the first sealing cover plate 4 is nested with a sealing ring 13. The sealing ring 13 can seal and fill the connection between the first sealing cover plate 4 and the semi-open structure of the mounting base 1 after they are fitted together, thereby ensuring the sealing effect of the assembly formed by the mounting base 1 and the support frame 3 after they are locked together, and then sealing and protecting the various structures fitted inside the mounting base 1 from corrosion.

[0053] In use, considering the corrosion protection of the threaded rod 72, the second sealing cover plate 14 is used to re-seal and assemble with the mounting base 1 through the threaded hole on the mounting base 1 to provide corrosion-resistant sealing protection for the threaded rod 72.

[0054] Considering the sealing effect of the first sealing cover plate 4 on the open structure of the mounting base 1, based on the assembly of the positioning sleeve 5 and the adjusting rod 10 by transmission locking, during the assembly process of the positioning sleeve 5 and the adjusting rod 10 in the inclined state, the force applied by the adjusting rod 10 to the inclined fitting of the positioning sleeve 5 in the negative direction can not only decompose the displacement force of horizontal movement, but also apply a vertical downward traction force to the fitting of the first sealing cover plate 4 on the open structure of the mounting base 1, increasing the connection strength between the first sealing cover plate 4 and the open structure of the mounting base 1. In conjunction with the sealing ring 13, the combined sealing effect of the mounting base 1 and the first sealing cover plate 4 is fully improved, and the sealing and corrosion protection effect of each structure inside the mounting base 1 is fully guaranteed.

[0055] Please see Figure 9 , Figures 11-12 A pressure sensor 16 and an L-shaped shaft 17 are provided in the middle 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 contact the sensing surface of the pressure sensor 16 fixed on the inner wall of the middle of the support curved plate 101. The pressure sensor 16 is electrically connected to a controller component 15 through wires. The controller component 15 includes a housing, and a processor, an alarm, a wireless transmission module and a battery module are installed inside the housing. The housing is fixed on the inner wall of the mounting base 1.

[0056] In practice, considering the theft problem by industry personnel who have access to specific wrenches, a solution is implemented using a further modified controller component 15, pressure sensor 16, and L-shaped shaft 17, as detailed below:

[0057] During the process of adjusting rod 10 and positioning sleeve 5 being fitted together, L-shaped shaft 17, which moves synchronously with the corresponding support curved plate 101, will move closer to pressure sensor 16. After adjusting rod 10 and positioning sleeve 5 are fitted and locked together, L-shaped shaft 17 will also apply a certain pressure to pressure sensor 16 and pressure sensor 16 will generate pressure data and transmit the pressure data to controller component 15.

[0058] When an industry professional with access to the specific wrench attempts to steal it, as the support frame 3 separates from the mounting base 1, the L-shaped shaft 17 will also separate from the pressure sensor 16 as the support curved plate 101 resets. At this time, the pressure data returns to zero. Simultaneously, the controller component 15 transmits the change in pressure data to the control center at the back end. At the same time, the alarm inside the controller component 15 starts to sound, increasing the psychological pressure on the thief and increasing the probability that he will give up, thus reducing the loss.
