Description

Technical Field

[0001] This utility model relates to a power generation transformer box, and more particularly to an energy-saving photovoltaic power generation transformer box. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It has advantages such as safety, reliability, wide distribution, and no pollution emissions, and has broad development prospects.

[0003] As an important component of solar photovoltaic power generation systems, prefabricated substations provide necessary power conversion, distribution, and protection functions for photovoltaic power generation systems. It is an integrated power distribution device that installs high-voltage switchgear, distribution transformers, low-voltage distribution devices, and related auxiliary equipment in one or more prefabricated enclosures within a fully enclosed steel structure box, effectively combining functions such as transformer voltage reduction and low-voltage power distribution.

[0004] Existing photovoltaic (PV) power generation transformers have significantly enhanced their airtightness to prevent internal moisture accumulation. However, this increased airtightness can lead to decreased heat dissipation performance, resulting in poor cooling of electrical equipment, especially the transformer. Currently, PV power generation transformers face challenges in heat dissipation due to varying application scenarios and demands. Furthermore, existing PV power generation transformers have compromised the space utilization of the transformer top cover, which has a relatively simple function, merely providing shelter from wind and rain, and cannot effectively utilize solar energy resources to achieve energy conservation and emission reduction goals. Therefore, to address these issues, an energy-saving PV power generation transformer is proposed. Utility Model Content

[0008] This utility model discloses an energy-saving photovoltaic power generation box-type transformer, wherein the rotating bracket includes a mounting plate, a mounting base, a first rotating rod, a second rotating rod, and a support base.

The mounting base is rotatably connected to one end of the first rotating rod, the other end of the first rotating rod is rotatably connected to one end of the second rotating rod, and the other end of the second rotating rod is rotatably connected to the support base. The support base is fixedly disposed on the top of the box body.

[0009] This utility model discloses an energy-saving photovoltaic power generation box transformer, wherein the mounting base and the first rotating rod, the first rotating rod and the second rotating rod and the second rotating rod and the support base are all rotatably connected by damping pins.

[0010] This utility model relates to an energy-saving photovoltaic power generation box transformer, wherein the top of the box is inclined.

[0013] This utility model relates to an energy-saving photovoltaic power generation box transformer, wherein each heat dissipation fan of the box is provided with a protective cover.

[0014] The difference between this utility model and the prior art is that this utility model converts solar energy into electrical energy through photovoltaic panels. Moreover, the box is equipped with a battery compartment for installing a battery pack and an electrical compartment for installing a transformer, as well as a regulating unit for controlling and regulating the temperature and humidity of the electrical compartment and the battery compartment. The photovoltaic panels transmit electrical energy to the battery pack for storage, and the battery pack transforms the electrical energy through the transformer to supply power to the outside. The regulating controller issues instructions based on the detection signals transmitted by the temperature detector and humidity detector to control the operation of the cooling fan and dehumidifier to cool and dehumidify the interior of the compartment, ensuring that the temperature and humidity values ​​inside the generator box are always kept within the normal operating threshold range.

Detailed Implementation

[0031] like Figure 1 , 2 As shown in Figures 5 and 6, this utility model discloses an energy-saving photovoltaic power generation box-type transformer, including a box body 01, on which a battery compartment 11 is provided; a photovoltaic power generation unit 02, which includes a rotating bracket 21 and photovoltaic panels 22 installed on the rotating bracket 21, with multiple rotating brackets 21 and photovoltaic panels 22 provided in a one-to-one correspondence, and multiple rotating brackets 21 are all located on the top of the box body 01; and an energy storage unit 03, which includes a battery pack 31, which is located inside the battery compartment 11, and multiple photovoltaic panels 22 are electrically connected to the battery pack 31.

[0032] The power generation principle of this utility model's power generation box is as follows: solar energy is converted into electrical energy through photovoltaic panels 22, making full use of solar energy resources to achieve the goal of energy conservation and emission reduction. To improve space utilization and facilitate transportation, the box body 01 is designed as a cuboid shape.

[0033] Each rotating bracket 21 is bolted to a photovoltaic panel 22 (i.e., a one-to-one correspondence). Multiple rotating brackets 21 are evenly bolted to the top of the housing 01. This ensures that the photovoltaic panels 22 do not block each other, increasing the area exposed to sunlight. It also facilitates adjustment of the photovoltaic panel angles, ensuring each panel receives sufficient sunlight, thereby improving power generation efficiency. The number of rotating brackets 21 and photovoltaic panels 22 can be appropriately increased or decreased according to actual power demand and the structure of the transformer substation, meeting power requirements while improving the space utilization of the transformer substation.

[0034] The battery pack 31 is composed of multiple batteries and is used to store the electrical energy generated by the photovoltaic panels 22. The battery pack 31 is fixed in the battery compartment 11 of the housing 01 by fixing rods. The battery compartment 11 is provided with wire channels, through which the wires connecting the multiple photovoltaic panels 22 pass into the housing and are electrically connected to the battery pack 31, realizing the transmission and storage of electrical energy. The number of batteries can be increased or decreased as needed according to the power generation requirements and the power generation of the photovoltaic panels 22 to meet different energy storage needs. The battery pack 31 is provided with an output interface. When power is needed, the cable of the output interface is connected to the external circuit system to supply power.

[0035] A charging controller can also be installed between the photovoltaic panel 22 and the battery pack 31 to protect both the photovoltaic panel 22 and the battery pack 31. It should be noted that the charging controller has the following characteristics:

[0036] Preventing overcharging: The photovoltaic panel 22 continuously generates electricity under sufficient sunlight. Without a controller, the battery may overcharge. Overcharging can damage the battery plates, accelerate water loss and plate aging, thus shortening the battery's lifespan. The controller monitors the battery voltage in real time. When the voltage reaches the set overcharge protection value, it automatically cuts off the charging circuit between the photovoltaic panel 22 and the battery to prevent overcharging.

[0037] Optimizing the charging process: Different types of batteries (such as lead-acid batteries and lithium batteries) have different charging characteristics. The controller can adopt an appropriate charging method, such as constant current charging or constant voltage charging, according to the type and state of the battery. In the initial stage of charging, the controller uses a large current for constant current charging to quickly replenish the battery's charge; when the battery voltage is close to full, it switches to constant voltage charging to prevent overcharging and make the internal charge of the battery more balanced.

[0038] Preventing over-discharge: During battery discharge, excessive discharge can lead to sulfation of the plates, reduced capacity, and even battery damage. The controller monitors the battery voltage in real time, and when the voltage drops to the set over-discharge protection value, it automatically cuts off the battery's discharge circuit to protect the battery from damage caused by over-discharge.

[0039] Load management: The controller can rationally allocate power based on the remaining battery charge and load demand. When the battery charge is low, the controller will prioritize power supply to important loads or reduce the power of unnecessary loads to extend battery life.

[0040] The working principle of this photovoltaic power generation transformer is as follows:

[0041] Power generation: The photovoltaic power generation box is placed in a well-lit location and fixed. The direction and angle of the photovoltaic panels 22 are adjusted. Multiple photovoltaic panels 22 convert light energy into electrical energy, which is then transmitted to the battery pack 31 in the battery compartment 11 for storage via wires.

[0042] Discharging: Connect the output interface of the battery pack 31 to external electrical equipment or circuit system via a cable to supply power.

[0043] like Figure 2 , 3 As shown in Figure 6, the enclosure 01 is also equipped with an electrical compartment 12, and the energy storage unit 03 also includes a transformer 32, which is installed in the electrical compartment 12 and electrically connected to the battery pack 31.

[0044] The transformer 32 is securely bolted to the electrical compartment 12 of the enclosure 01 to prevent shaking and circuit interruptions caused by vibration. A cable hole is provided on the partition between the electrical compartment 12 and the battery compartment 11. Cables connecting to the output interface of the battery pack 31 pass through the cable hole and are electrically connected to the transformer 32. The transformer 32 can transform the electrical energy in the battery pack 31 and output it to the outside according to power demand, thereby enhancing the adaptability of the generator box transformer to different power consumption scenarios and meeting diverse power needs.

[0045] like Figure 1 , 8 As shown in Figure 9, the rotating bracket 21 includes a mounting plate 211, a mounting base 212, a first rotating rod 213, a second rotating rod 214, and a support base 215. The photovoltaic panel 22 is mounted on the mounting plate 211, and the mounting plate 211 is mounted on the mounting base 212. The mounting base 212 is rotatably connected to one end of the first rotating rod 213, and the other end of the first rotating rod 213 is rotatably connected to one end of the second rotating rod 214. The other end of the second rotating rod 214 is rotatably connected to the support base 215, and the support base 215 is fixedly mounted on the top of the housing 01. The mounting base 212 is rotatably connected to the first rotating rod 213, the first rotating rod 213 is rotatably connected to the second rotating rod 214, and the second rotating rod 214 is rotatably connected to the support base 215 via damping pins 23.

[0046] The rotating bracket 21 is fixed to the top of the housing 01 via bolts or locking pins through the support base 215. The upper end of the first rotating rod 213 is rotatably connected to the mounting base 212 via the damping pin 23. The lower end of the first rotating rod 213 is rotatably connected to the lower end of the second rotating rod 214 via the damping pin 23. The lower end of the second rotating rod 214 is also rotatably connected to the support base 215 via the damping pin 23. The mounting plate 211 is firmly fixed to the upper surface of the mounting base 212 with bolts. The photovoltaic panel 22 is fixed to the upper surface of the mounting plate 211 with bolts. The rotating bracket 21 firmly fixes the photovoltaic panel 22, thereby ensuring its stable operation. Among the three rotating nodes—the second rotating rod 214 and the mounting base 212, the second rotating rod 214 and the first rotating rod 213, and the first rotating rod 213 and the support base 215—at least one is a forward-backward rotation and at least one is a left-right rotation. This constitutes a telescopically adjustable rotating bracket 21 structure. When adjusting the rotating bracket 21, the telescopic length of the rotating bracket 21 can be adjusted in the up-down direction, the tilt angle of the rotating bracket 21 in the left-right direction can be adjusted by rotating it left-right, and the tilt angle of the rotating bracket 21 in the forward-backward direction can be adjusted by rotating it forward-backward. This ensures that the photovoltaic panel 22 has a sufficiently good light-receiving angle and a sufficiently long illumination time, thereby increasing the power generation of the power generation transformer.

[0047] It should be noted that the damping pin 23 has the following characteristics:

[0048] Controllable rotational resistance: The damping pin 23 provides a certain amount of rotational resistance, which can be adjusted according to actual needs. When the first rotating rod 213, the second rotating rod 214, the mounting base 212, and the support base 215 rotate around the damping pin 23, there will be no sudden, uncontrolled rotation. Instead, a certain external force needs to be applied to overcome the damping force to rotate. Furthermore, the damping force is always present during rotation, ensuring the smoothness of rotation.

[0049] Angle holding: Thanks to the damping force, the rotating bracket 21 can remain in that position after rotating to any angle. As long as the applied external force does not exceed the holding force provided by the damping force, the rotating bracket 21 will not change its angle due to its own weight or slight vibration.

[0050] Buffering and shock absorption: During the rotation adjustment of the rotating bracket 21, the damping pin 23 can play a buffering role. When the rotating bracket 21 is subjected to a sudden external force impact, the damping force will absorb and disperse some of the energy, reduce the impact force on the rotating bracket 21, and avoid damage caused by excessive instantaneous impact force.

[0051] Smoothness of movement: Compared with ordinary pins and universal ball joints, the damping pin 23 connection makes the rotation of the rotating bracket 21 smoother and more stable. It can reduce the stuttering and jumping phenomena during rotation, and ensure the continuity and stability of rotation.

[0052] The setting of the damping pin 23 not only makes the angle adjustment of the photovoltaic panel 22 easier, but also simplifies the structure of the rotating bracket 21 and reduces production costs.

[0053] like Figure 3 , 4 As shown in Figure 7, the top of the enclosure 01 is inclined. The enclosure 01 is equipped with a door 13, and the door 13 is equipped with a ventilation grille 14.

[0054] Both the battery compartment 11 and the electrical compartment 12 of the enclosure 01 are equipped with enclosure doors 13. The enclosure doors 13 protect the battery pack 31, transformer 32 and other electrical equipment inside the compartment. Depending on the actual situation, enclosure doors 13 can be installed on one side or the front and rear sides of the battery compartment 11 and the electrical compartment 12 to facilitate the loading, unloading and installation of electrical equipment.

[0055] The top of the housing 01 adopts an inverted V-shaped inclined design with a high center and low sides, or it can adopt an inclined design with one side higher and one side lower. In this way, rain and snow will not accumulate on the top of the housing 01 during rainy or snowy weather, thus avoiding unnecessary impact on the rotating bracket 21 and photovoltaic panel 22 caused by the accumulated rain and snow.

[0056] Each door 13 is equipped with a ventilation grille 14 for ventilation and heat dissipation, allowing heat to escape from the cabin. Furthermore, the top of the enclosure 01 extends beyond its four side walls, and each door 13 is equipped with a baffle above it. These baffles and the top of the enclosure 01 protect the doors 13 from rain, snow, or dust entering the cabin through the ventilation grille 14 or gaps in the doors 13, thus preventing damage to the electrical components inside.

[0057] like Figure 7 As shown, this utility model discloses an energy-saving photovoltaic power generation transformer, which also includes an adjustment unit 04. The adjustment unit 04 includes an adjustment controller 41, a humidity detector 42, a temperature detector 43, a dehumidifier 44, and multiple cooling fans 45, all of which are electrically connected to the transformer 32. The adjustment controller 41 is located in the electrical compartment 12; the humidity detector 42, the temperature detector 43, and the dehumidifier 44 are all located in the battery compartment 11; the multiple cooling fans 45 are respectively located on the side walls of the electrical compartment 12 and the battery compartment 11; the humidity detector 42, the temperature detector 43, the dehumidifier 44, and the multiple cooling fans 45 all establish information interaction with the adjustment controller 41.

[0058] The regulating unit 04 is used to control and regulate the temperature and humidity of the electrical compartment 12 and the battery compartment 11. To improve the space utilization of the generator transformer, the temperature detector 43, humidity detector 42, and dehumidifier 44 can be installed on the inner wall of the battery compartment 11 or the inner wall of the door 13. The regulating controller 41 is installed on the inner wall of the electrical compartment 12. The cooling fan 45 is installed on the side walls of the battery compartment 11 and the electrical compartment 12 and is located above the door 13. The position of the cooling fan 45 can be arranged according to the actual situation. For example, one cooling fan 45 can be installed on each side wall of the battery compartment 11 and the electrical compartment 12, or the number can be increased or decreased appropriately according to the heat dissipation requirements.

[0059] The regulating controller 41, humidity detector 42, temperature detector 43, dehumidifier 44 and cooling fan 45 are all electrically connected to the battery pack 31 through wires and are all powered by the battery pack 31. In this way, the external power supply and complex wiring connection are eliminated, which not only simplifies the structure of the generator box transformer, but also helps to reduce costs.

[0060] During operation, temperature detector 43 and humidity detector 42 are used to monitor the temperature and humidity inside the battery compartment 11 in real time and transmit the detection data to the regulating controller 41. The regulating controller 41 has preset temperature and humidity thresholds. It judges the temperature and humidity in real time based on the received temperature and humidity signals. When the temperature inside the compartment exceeds the set temperature threshold, the regulating controller 41 sends a command to the cooling fan 45. The cooling fan 45 starts to rotate to dissipate the heat inside the compartment until the temperature inside the compartment is lower than the threshold, at which point the cooling fan 45 stops working.

[0061] Similarly, when the humidity value inside the cabin exceeds the set humidity threshold, the control controller 41 sends a command to the dehumidifier 44, and the dehumidifier 44 starts to work to dehumidify the cabin. The moisture is discharged through the ventilation grille 14 on the door 13 until the humidity value inside the cabin is lower than the threshold, at which point the dehumidifier 44 stops working.

[0062] Through this regulation mechanism, the temperature and humidity inside the transformer substation are always kept within the normal operating threshold range. On the one hand, this ensures that the transformer substation can work continuously and stably; on the other hand, it avoids situations such as high temperature causing damage to the battery pack 31, fire, and high humidity causing short circuits, thereby improving the safety and stability of the transformer substation.

[0063] like Figure 1 , 2 As shown in Figure 5, each cooling fan 45 of the housing 01 is provided with a protective cover 46.

[0064] Each cooling fan 45 is covered by a protective cover 46, which is securely installed on the enclosure 01 with bolts. The protective cover 46 is equipped with a dustproof net and dustproof cotton inside. While ensuring that the heat inside the enclosure can be discharged from the protective cover 46, the dustproof net and dustproof cotton prevent sand and dust and other substances from entering the enclosure and damaging the electrical equipment, ensuring the stable operation of the generator box and thus enhancing the safety of the generator box.
