[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Figure 7 , an energy-saving box transformer for energy storage shown in the figure includes a box-type transformer substation 1, in which independent transformer chambers, high-voltage chambers, low-voltage chambers and energy storage chambers are arranged in sequence; it also includes: a support frame 2, which is respectively installed in the transformer chamber, the high-voltage chamber and the low-voltage chamber, a support bracket 3 is slidably installed in the support frame 2, a spring 9 is arranged on the top of the support frame 2 and the bottom of the support bracket 3, a micro-generator 6 is arranged inside the support frame 2, and a linkage component 4 for driving the micro-generator 6 to rotate is arranged between the support frame 2 and the support bracket 3; the linkage component 4 includes a guide column 10 fixedly arranged on the top of the support frame 2, and the guide column The outer sleeve of 10 is provided with a linkage plate 11 which is slidably connected and fixedly connected to the bottom of the support frame 3, and a linkage rod 12 which is rotatably connected is provided on the side wall of the linkage plate 11. The linkage assembly 4 also includes a support frame 13 which is fixedly arranged on the inner bottom of the support frame 2, and a rotating disk 14 which is rotatably connected is provided inside the support frame 13, and one side of the outer wall of the rotating disk 14 is rotatably connected to an end of the linkage rod 12 away from the guide column 10. A backup battery 7 is provided on the inner top of the support frame 2, and the backup battery 7 is electrically connected to the micro generator 6, wherein the micro generator 6 can adopt a hand-cranked DC micro generator, and its power adopts a 220V model.

[0022] In this scheme, by setting a rotating linkage rod 12 between the linkage plate 11 and the rotating disk 14, when in use, when the vibration force generated by the operation of the transformers in the transformer room, high-voltage room and low-voltage room in the box-type substation 1, the high-voltage switch cabinet and the electrical components in the low-voltage switch cabinet act on the support frame 3, the vibration force will drive the support frame 3 to slide up and down inside the support frame 2, so that the linkage plate 11 below can be driven to move synchronously. At this time, the synchronously moving linkage rod 12 will squeeze the linkage rod 12, and then the linkage rod 12 can drive the rotating disk 14 to rotate inside the support frame 13. Therefore, the up and down swinging force of the device when working can be converted into a driving force for horizontal rotation, so that the externally connected micro-generator 6 can be driven to work, realize energy conversion, and the converted electric energy is purely supplied to the backup battery 7, and the auxiliary devices such as the lighting and dehumidifier in the box-type substation 1 are used, without using the electric energy of the device, so the energy-saving effect of the device in the later use can be improved; It should be noted that: through the setting of the spring 9, when the working force of the components in the box-type substation 1 is transmitted to the support frame 3, the support frame 3 will transmit the force to the spring 9. When the spring 9 is subjected to the downward extrusion force, it will shrink and store energy. When the spring 9 shrinks to the extreme point and resets, the support frame 3 can be smoothly reset, so that the subsequent up and down reciprocating motion of the support frame 3 can be smoother.

[0023] For further information, see Figure 1 and Figure 7 The transformer room, high-voltage room, low-voltage room and energy storage room in the box-type substation 1 are all equipped with lighting lamps and dehumidifiers for dehumidification, and the lighting lamps and dehumidifiers are electrically connected to the backup battery 7, a battery pack for electric energy storage is arranged inside the energy storage room, the transformer room includes a transformer, the high-voltage room includes a high-voltage switch cabinet, and the low-voltage room includes a low-voltage switch cabinet; Among them, the setting of the lighting lamp can facilitate the staff to carry out operations such as copying and maintenance inside the box-type substation cabinet, and the setting of the dehumidifier can reduce the humidity of the air in the box-type substation 1 during the rainy weather, thereby reducing the probability of damage to the device caused by the relatively high humidity of the air in the box-type substation 1 during the rainy weather; It should be noted that lighting, dehumidifier, battery pack, transformer, high-voltage switchgear and low-voltage switchgear are not shown in the figure.

[0024] Example 2: Please refer to Figure 2 and Figure 6 This embodiment further explains the first embodiment, and the difference is that an air bag 8 is set up between the support frame 2 and the support frame 3 to improve the air circulation in the box-type substation 1; Specifically, the top of the support frame 2 and the bottom of the support frame 3 are both provided with a fixedly connected mounting plate 24, an airbag 8 is mounted between the two mounting plates 24, and a plurality of connected air intake pipes 25 and exhaust pipes 26 are respectively provided on both sides of the inside of the airbag 8, and a one-way valve 27 is provided on each of the air intake pipes 25 and the exhaust pipes 26.

[0025] In this solution, by setting a one-way valve 27 on the air inlet pipe 25 and the exhaust pipe 26, when the airbag 8 is extended and retracted by an external force, the gas inside the airbag 8 will be discharged outward through the one-way valve 27 on the exhaust pipe 26 during contraction, so that the gas can flow in a set direction, thereby increasing the gas circulation effect in the box-type substation 1. When the airbag 8 is extended, the gas on the other side of the box-type substation 1 will be sucked into the airbag 8 through the air inlet pipe 25, so that the airbag 8 can discharge the gas from the exhaust pipe 26 later. Through this one-sided suction and one-sided discharge method, the gas can be circulated more evenly inside the box-type substation 1.

[0026] It should also be noted that, see Figure 1 The ends of the air inlet pipe 25 and the exhaust pipe 26 are both located between the support frame 2 and the support bracket 3, thereby improving the integrity of the device.

[0027] Example 3: Please refer to Figure 4 and 5 , this embodiment further explains the first embodiment, and the difference lies in the installation of multiple sets of gears A to increase the rotation speed of the rotating disk 14 in the linkage assembly 4 output outward; Specifically, a transmission assembly 5 is arranged at the end of the micro-generator 6, and the transmission assembly 5 can increase the rotation rate of the linkage assembly 4 to drive the micro-generator 6. The transmission assembly 5 includes a plurality of support sheets a15 fixedly installed at the bottom of the support frame 2, and a rotationally connected shaft a17 is inserted at the upper part of the support sheets a15, and a rotationally connected shaft b18 is inserted at the lower part of the two support sheets a15 near the linkage rod 12. The end of the shaft b18 is fixedly connected to the outer wall of the corresponding rotating disk 14. The transmission assembly 5 also includes a plurality of support sheets a15 fixedly installed at the bottom of the support frame 2, and a plurality of support sheets a15 are inserted at the upper part of the support sheets a15. The shaft b18 is ... A support piece b16 is provided between two adjacent support pieces a15 on one side of the rod b18, a rotatably connected shaft c19 is provided between the support piece b16 and the support piece a15, and the end of the shaft c19 is fixedly connected to the shaft end of the micro-generator 6, a fixedly connected driving gear 20 is provided on the outside of the shaft b18, a transmission gear a21 is provided on the outside of the shaft a17 at a position opposite to the driving gear 20, a transmission gear b22 is provided on the outside of the shaft a17 at a position opposite to the shaft c19, and an output gear 23 is provided on the outside of the shaft c19 at a position opposite to the transmission gear b22.

[0028] In this solution, by setting a relatively large driving gear 20 to mesh with a relatively small transmission gear a21, when the rotating disk 14 drives the driving gear 20 to rotate through the shaft b18 and transmits it to the shaft a17, a primary increase in the rotation speed can be achieved. Similarly, by meshing the relatively large transmission gear b22 with the relatively small output gear 23, when driving the shaft c19 to rotate, a secondary adjustment of the rotation speed can be achieved, so that the shaft c19 can smoothly drive the micro generator 6 to generate electricity.
