Description

Technical Field

[0001] This invention relates to the field of power transformer box technology, and particularly to an outdoor power transformer box. Background Technology

[0002] Outdoor power substations are key "hub devices" of power systems in outdoor scenarios. Their core function is to connect power transmission with end-user power consumption, solve the needs of power conversion, distribution, protection and control in complex outdoor environments, and directly support the stable operation of outdoor power consumption scenarios such as urban public facilities, residential life and industrial production.

[0003] Outdoor power substations need to withstand the interference of the natural environment for a long time, and the electrical components such as transformers inside the substations have a normal operating temperature range (-10℃ to +40℃). However, existing outdoor power substations usually lack active temperature control design and rely solely on natural ventilation through louvers. Moreover, the ventilation range of the louvers cannot be adjusted. In hot summer afternoons in hot regions, the temperature inside the box can reach above 60℃, exceeding the circuit breaker's operating limit of 55℃, leading to frequent tripping. In some frigid winter regions, the temperature inside the box may drop as low as -30℃, causing the electrical components such as transformers to malfunction. Furthermore, with the louvers constantly open, rainwater may enter the substation during heavy rain or short-term heavy precipitation, damaging the electrical components inside. Additionally, in the event of a blizzard, the insufficient load-bearing capacity of the top of the box may cause it to collapse.

[0004] Therefore, there is an urgent need to provide outdoor power transformer boxes that can regulate heat dissipation and are protected from rain and snow. Summary of the Invention

[0005] Therefore, it is necessary to provide an outdoor power transformer box designed to solve the problems that arise when using existing outdoor power transformer boxes.

[0012] The outdoor power transformer also includes a drive unit connected inside the triangular top and used to simultaneously drive the adjustment section and the toggle section. The adjustment section adjusts the ventilation volume of the louvers, and the toggle section adjusts the opening and closing of the exhaust port.

[0013] The louvers and top unit are adjusted in multiple states by a drive unit. When the temperature is high, the louvers and top unit are fully opened. When the temperature is low or it is raining, the louvers and top unit are closed. When it is snowing, the actuating part on the top unit shakes off the snow.

The upper and lower frame walls of the guide frame are slidably connected with a lifting rod. A plurality of evenly distributed adjustment rods that cooperate with corresponding adjustment blocks are installed on one end of the lifting rod near the mounting frame.

[0016] Preferably, the adjusting part further includes a connecting sleeve that is slidably sleeved on the upper end of the lifting rod, and a spring is installed between the top wall of the connecting sleeve and the top end of the lifting rod.

[0017] Preferably, the actuating part includes two baffles symmetrically installed on the upper end of the triangular apex, and two actuating plates symmetrically distributed front and back are hinged between the two baffles. Multiple arc-shaped rods that slide through the inclined section of the triangular apex are installed at the lower end of the actuating plates.

[0018] Preferably, the actuating part further includes a guide protrusion installed in the middle between the two baffles, a filter screen installed in the exhaust hole, and a sealing gasket fixedly connected to the actuating plate provided diagonally above the exhaust hole.

[0019] Preferably, the traction unit includes a U-shaped guide rod installed on the upper end of the lifting plate with its opening facing downward. A sliding block is slidably sleeved on the middle section of the U-shaped guide rod, and a hinge seat that is hinged to the lower end of the arc-shaped rod is installed on the upper end of the sliding block.

[0020] Preferably, the lifting part includes a T-shaped plate installed at the end of the lifting plate and positioned horizontally, and at least two snap-fit ​​pieces are installed at the lower end of the longitudinal section of the T-shaped plate, and the snap-fit ​​pieces are detachably connected to the connecting sleeve.

[0021] Preferably, the louvered panel has stepped openings at both the top and bottom ends, with the stepped opening at the bottom of the upper louvered panel matching the stepped opening at the top of the adjacent lower louvered panel.

[0022] Preferably, the adjusting block consists of a circular plate and a U-shaped frame, with the circular plate fixedly connected to the end of the rotating shaft and the U-shaped frame inserted into the corresponding adjusting rod.

[0024] In summary, the present invention has the following beneficial technical effects: 1. The working range of the louvers and exhaust holes used in the present invention can be adjusted according to the environment at that time, which can control the size of the airflow and thus control the working temperature inside the transformer box, keeping it at a normal working temperature, effectively avoiding abnormalities in transformer operation caused by environmental factors, and improving the working life of the transformer.

[0025] The louvers and top unit used in this invention can be adjusted in multiple states through a drive unit. When the temperature is high, the louvers and top unit are opened, which effectively improves the heat dissipation inside the transformer box. When the temperature is low or it is rainy, the louvers and top unit are closed to prevent rainwater from entering the transformer box. When it snows, the actuating part on the top unit can shake off the snow to prevent snow from damaging the transformer box, thus effectively increasing the service life of the power transformer box.

Detailed Implementation

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] See Figures 1-3 An outdoor power transformer box includes a base 1, wherein a plurality of evenly distributed drainage holes 10 are provided in the middle of the base 1.

[0038] See Figures 1-3 The outdoor power transformer also includes a transformer box body 2 installed on the upper part of the base 1.

[0039] In practice, the base 1 and the transformer box 2 are assembled before installation. Then, the outdoor power transformer box is transported to the required installation location using existing transportation equipment. A cement foundation is poured on the ground at the required installation location. Then, the base 1 and the transformer box 2 are hoisted onto the cement foundation using existing hoisting equipment and fixed in place. The transformer box 2 is equipped with an opening and closing door, and the drainage hole 10 on the base 1 is used for drainage inside the transformer box 2.

[0040] See Figure 1 , Figure 3 and Figure 5 The outdoor power transformer box also includes a top unit 4 set at the top of the transformer box body 2. The top unit 4 includes a triangular top 40 installed at the top of the transformer box body 2. Multiple evenly distributed exhaust holes 41 are opened on the two inclined sections of the triangular top 40. A toggle part 42 is connected to the upper end of the triangular top 40.

[0041] In practice, after the transformer box 2 is installed, the triangular top 40 is hoisted to the upper end of the transformer box 2 using existing hoisting equipment. The triangular top 40 is fixedly connected to the upper end of the transformer box 2 by welding or detachable installation.

[0042] See Figure 1 , Figure 3 and Figure 5 The outdoor power transformer also includes a drive unit 5 connected inside the triangular top 40 and used to simultaneously drive the adjustment part 32 and the toggle part 42. The adjustment part 32 adjusts the ventilation volume of the louver part 31, and the toggle part 42 adjusts the opening and closing of the exhaust hole 41.

[0043] See Figure 1 , Figure 3 , Figure 5 and Figure 6 The drive unit 5 includes a mounting plate 50 installed on the inner wall of the triangular top 40. A drive component 51 is installed in the middle of the mounting plate 50. A lifting plate 52 is installed at the lower end of the drive component 51. Multiple traction parts 53 are installed on both sides of the upper end of the lifting plate 52. Lifting parts 54 are connected to both the left and right ends of the lifting plate 52.

[0044] In actual operation, while the triangular top 40 is being installed, the triangular top 40 is fixed to the drive component 51 by the mounting plate 50. The drive component 51 is an existing lifting drive structure, such as a hydraulic push rod or an electric push rod.

[0045] See Figure 1 , Figure 3 and Figure 4The outdoor power transformer box also includes multiple ventilation units 3 located on the left and right walls of the transformer box body 2. Each ventilation unit 3 includes ventilation holes 30 on the corresponding walls of the transformer box body 2. The ventilation holes 30 are provided with louvers 31 and filter plates 33 on the inner and outer sides of the transformer box body 2, respectively.

[0046] In practice, after the triangular top 40 is installed, multiple filter plates 33 are fixedly connected to the transformer box 2 by means of threaded connection or welding. The filter plates 33 are used to filter the corresponding ventilation holes 30. The ventilation holes 30 are used for ventilation inside the transformer box 2 and facilitate heat exchange inside the transformer box 2, so as to reduce the temperature of the transformer box 2.

[0047] See Figure 1 and Figure 4 The louvered part 31 includes a mounting frame 310 that is bolted to the inner surface of the transformer box 2. Multiple rotating shafts 311 are connected through the front and rear frame walls of the mounting frame 310 and are evenly distributed from top to bottom. A louvered plate 312 located inside the mounting frame 310 is installed in the middle of the rotating shaft 311, and an adjusting block is installed at the end of the rotating shaft 311.

[0048] See Figure 4 The louvered panel 312 has stepped openings at both the upper and lower ends. The stepped opening at the lower end of the upper louvered panel 312 cooperates with the stepped opening at the upper end of the adjacent lower louvered panel 312.

[0049] In practice, after multiple filter plates 33 are installed, multiple mounting frames 310 are then bolted onto the inner surface of the transformer box 2 and positioned at the corresponding ventilation holes 30. Multiple rotatable louvers 312 can control the opening and closing of the ventilation holes 30 and also control the ventilation volume of the ventilation holes 30, which facilitates heat dissipation of the transformer box 2 under different temperatures and weather conditions.

[0050] See Figure 4 The louvered part 31 is connected to an adjustment part 32. The adjustment part 32 includes a guide frame 320 installed on the outside of the vertical section of the mounting frame 310. The upper and lower frame walls of the guide frame 320 are slidably connected to a lifting rod 321. A plurality of evenly distributed adjustment rods 322 that cooperate with the corresponding adjustment blocks are installed on one end of the lifting rod 321 near the mounting frame 310.

[0051] See Figure 4 The adjusting block is composed of a circular plate 313 and a U-shaped frame 314. The circular plate 313 is fixedly connected to the end of the rotating shaft 311, and the U-shaped frame 314 is inserted into the corresponding adjusting rod 322.

[0052] See Figure 4The adjustment part 32 also includes a connecting sleeve 323 that is slidably sleeved on the upper end of the lifting rod 321, and a spring 324 is installed between the top wall of the connecting sleeve 323 and the top end of the lifting rod 321.

[0053] See Figure 4 The lifting part 54 includes a T-shaped plate 540 installed at the end of the lifting plate 52 and positioned horizontally. Two snap-fit ​​pieces 541 are installed at the lower end of the longitudinal section of the T-shaped plate 540. The snap-fit ​​pieces 541 are detachably connected to the connecting sleeve 323.

[0054] In actual operation, the snap-fit ​​component 541 includes a snap-fit ​​plate and a snap-fit ​​rod. While the mounting frame 310 is being installed, the mounting frame 310, via the guide frame 320, moves the connecting sleeve 323 at the upper end of the lifting rod 321 to the snap-fit ​​plate. Then, the snap-fit ​​rod connects the connecting sleeve 323 to the snap-fit ​​plate, thus connecting the adjusting part 32 to the lifting part 54. It should be noted that the selected spring 324 has high elastic strength, sufficient to ensure that the lifting part 54 pulls the lifting rod 321 upwards via the spring 324. 1. Multiple U-shaped frames 314 are rotated by multiple adjusting rods 322. The multiple U-shaped frames 314 drive multiple circular plates 313 and multiple rotating shafts 311 to rotate. The multiple rotating shafts 311 simultaneously drive multiple louvers 312 to rotate, thereby changing the ventilation volume of the ventilation holes 30. When the lifting plate 52 rises, the adjusting part 32 is moved by the lifting part 54, causing the multiple louvers 312 to rotate upward. When the lifting plate 52 falls, the adjusting part 32 is moved by the lifting part 54, causing the multiple vertical louvers 312 to rotate downward.

[0055] See Figure 1 , Figure 3 and Figure 5 The actuating part 42 includes two baffles 420 symmetrically installed on the upper end of the triangular top 40. Two actuating plates 421 symmetrically distributed front and back are hinged between the two baffles 420. Multiple arc-shaped rods 422 that slide through the inclined section of the triangular top 40 are installed at the lower end of the actuating plates 421.

[0056] See Figure 1 , Figure 3 and Figure 5 The actuating part 42 also includes a guide protrusion 423 installed in the middle between the two baffles 420, a filter screen 424 installed in the exhaust hole 41, and a sealing gasket 425 fixedly connected to the actuating plate 421 is provided diagonally above the exhaust hole 41.

[0057] See Figure 1 , Figure 3 , Figure 5 and Figure 6The traction unit 53 includes a U-shaped guide rod 530 installed on the upper end of the lifting plate 52 with the opening facing downward. A sliding block 531 is slidably sleeved on the middle section of the U-shaped guide rod 530. A hinge seat 532 that is hinged to the lower end of the arc-shaped rod 422 is installed on the upper end of the sliding block 531.

[0058] In actual operation, the drive unit 51 can be activated via remote control. The drive unit 51, through the lifting plate 52, drives the sliding block 531 and hinge seat 532 on the U-shaped guide rod 530 to push the arc-shaped rod 422 upwards, causing the actuating plate 421 to rotate upwards. This opens multiple exhaust holes 41 on the triangular top 40. The opened exhaust holes 41 are used for heat exchange in the transformer box 2, facilitating the removal of hot air from inside the transformer box 2. The filter screen 424 is used to filter the exhaust holes 41. Simultaneously, the lifting plate 52, through the two snap-fit ​​pieces 541 on the T-shaped plate 540, drives the two connecting sleeves 323 to move. The connecting sleeves 323, through the spring 324, drive the lifting rod 321 upwards, causing multiple louvers 312 to be in a parallel state. At this time, the ventilation volume of the ventilation holes 30 is at its maximum (e.g., Figure 3 As shown), multiple ventilation holes 30 and multiple exhaust holes 41 work together to adapt to high-temperature environments, effectively improving the heat dissipation effect inside the transformer box 2. A fan can also be installed inside the transformer box 2 to further improve the heat dissipation effect inside the transformer box 2.

[0059] During rainy weather, the drive unit 51 operates, reducing the gap between the actuating plate 421 and the triangular apex 40. This causes the two sides of the actuating plate 421 to fit against the two baffles 420, leaving only a downward-facing opening between the actuating plate 421 and the triangular apex 40. Furthermore, the tilted actuating plate 421 guides rainwater, effectively preventing it from entering the transformer box 2 through the vent 41 and thus avoiding damage to the transformers inside. Simultaneously, the operation of the drive unit 51 controls multiple louvers 312 to remain tilted, preventing rainwater from entering the transformer box through the ventilation holes 30. Inside the enclosure 2, in the event of heavy rain, the drive unit 51 can cause multiple louvers 312 to be in a vertical position, meaning the ventilation holes 30 are closed. The stepped openings on adjacent louvers 312 cooperate with each other to prevent gaps between the closed louvers 312, effectively preventing rainwater from entering the transformer enclosure 2 through the ventilation holes 30. At this time, due to the action of the spring 324 connecting the lifting rod 321 and the connecting sleeve 323, there is still a certain gap between the actuating plate 421 and the upper end of the triangular top 40 when the ventilation holes 30 are closed, ensuring continuous heat dissipation (e.g., Figure 7 (As shown).

[0060] At low temperatures, to ensure the normal operation of the transformers inside the transformer box 2, they need to be kept within the normal operating temperature range. First, the ventilation holes 30 are sealed. After the ventilation holes 30 are sealed, the drive unit 51 continues to drive the sliding block 531 and hinge seat 532 on the U-shaped guide rod 530 downwards via the lifting plate 52, pulling the arc-shaped rod 422 downwards. During this process, because the spring 324 can be compressed, the connecting sleeve 323, which moves downwards under force, acts as a spring... Spring 324 is compressed and slides on lifting rod 321 to avoid obstructing the descent of lifting plate 52. Simultaneously, sliding block 531 slides on U-shaped guide rod 530 to avoid affecting the movement of arc rod 422. Arc rod 422 drives actuating plate 421 to press tightly against the upper end of triangular apex 40. Sealing gasket 425 on actuating plate 421 seals vent 41, slowing down the loss of internal temperature of transformer box 2 and reducing the rate of heat loss, ensuring the transformer operates in a suitable environment (e.g., ...). Figure 8 (As shown).

[0061] In snowy weather, the reciprocating operation of the drive component 51 can cause the actuating plate 421 to rotate back and forth, which is used to shake off the snow on the actuating plate 421 and prevent the accumulated snow from damaging the triangular top 40 and the transformer box 2.

[0062] It should be noted that existing transformer box enclosures 2 also have louvered structures, but the louvered windows face downwards and remain fixed. Although they can provide ventilation and heat dissipation, the size of the heat dissipation channel cannot be changed; the heat dissipation intensity can only be adjusted by the natural wind speed. Some transformer boxes also have fans installed inside, but some enclosures with fans, lacking temperature sensors, are constantly running, exhausting air even at low temperatures, which exacerbates temperature fluctuations inside the transformer box. However, in the solution of this invention, the louvered section 31 and the top unit 4 can be simultaneously adjusted in multiple states through the drive unit 5. At high temperatures, the louvered section 31 and the top unit 4 are fully opened; at low temperatures and in rainy weather, the louvered section 31 and the top unit 4 are closed; and in snowy weather, the toggle switch on the top unit 4... Section 42 can shake off accumulated snow, effectively increasing the service life of the power substation. While the present invention adds louvers 31, actuation section 42, and drive unit 5 compared to existing technologies, these are all conventional mechanical structures without any high-cost precision parts. Therefore, the cost of adding these structures is low. Furthermore, a single drive unit 5 can simultaneously drive louvers 31 and actuation section 42, effectively reducing the drive source and lowering costs. Compared to the costs of repeated repairs and replacements required by existing technologies due to substation malfunctions or damage under high temperature, low temperature, rain, and snow conditions, the cost of adding these structures is negligible. The above technical solution of the present invention is a specific improvement based entirely on the aforementioned existing technology and aimed at solving technical problems.

[0063] Furthermore, the terms "first," "second," "number one," and "number two" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "number one," or "number two" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0064] In this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0065] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
