Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, in particular to a box-type transformer substation with a protective structure. Background Art

[0002] A box-type substation is a factory-prefabricated indoor and outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a certain wiring scheme. Existing box-type substations with high protection levels (such as IP44) have strong sealing of the casing and excellent dust and water resistance, but the ventilation path is restricted, the natural heat dissipation efficiency is low, and it is easy to cause the internal temperature to exceed the standard. Box-type substations with low protection levels (such as IP33) can be designed with ventilation holes, shutters and other structures on the casing to improve the heat dissipation capacity, but dust and rainwater can easily enter, which may cause equipment flashover, corrosion and other problems.

[0003] For example, an outdoor box-type substation with a protective structure with the announcement number CN221669406U includes a box body, the bottom of the box body is fixedly connected to a base, a cavity is opened inside the base, a threaded rod is rotatably connected to the center of the bottom of the inner wall of the cavity, the upper end of the threaded rod is rotatably connected to the top of the inner wall of the cavity, the upper end of the outer wall of the threaded rod is fixedly connected to a first bevel gear, one side of the first bevel gear is meshed with a second bevel gear, and one side of the second bevel gear is fixedly connected to a rotating shaft; for this outdoor box-type substation with a protective structure, turning the handle can drive the rotating shaft to rotate, thereby driving the threaded rod to rotate, and at the same time the threaded rod rotates, the movable plate can drive the universal wheel to move downward, and when the universal wheel extends out of the base, the box body can be easily transported. By setting a buffer component between the moving plate and the universal wheel, the substation can be made more stable during movement, thereby providing better protection for the substation. However, since the box-type substation is designed for installation in an open environment, it must be able to withstand different weather conditions. For outdoor box-type substations, while anti-collision protection is required, appropriate windproof measures must also be taken to ensure the normal operation of the box-type substation in a high wind speed environment, avoid equipment damage or safety accidents caused by strong winds, and improve the working reliability and service life of the substation. In addition, corresponding sealing protection should be set for the connection between the box door and the door frame to reduce foreign matter splashing into the interior of the substation, thereby ensuring the normal operation of the equipment inside the substation box.

[0004] Therefore, a box-type substation with a protective structure is proposed to solve the above-mentioned problems. Summary of the Invention

The rotating member 57 is rotatably connected to the protective plate 54. A connecting block 59 is hinged at the other end of the inclined rod 58. The connecting block 59 is rotatably connected to the sliding seat 510. The sliding seat 510 is slidably connected to the spiral groove 56.

[0050] The pressing part includes support blocks 514 fixedly mounted on the front and back sides of the base plate 2 respectively. The lower part of the protective plate 54 close to the mounting box 1 is connected to a sliding rod 512. The outer side of the sliding rod 512 is sleeved with a sliding bar 515. The sliding bar 515 is slidably mounted with the support block 514. The sliding bar 515 is located directly below the sealing door 4.

[0051] The supporting part includes an inclined plate 513 installed at one end of the sliding rod 512, the inclined plate 513 is in contact with the top surface of the side panel 51, and the two ends of the sliding rod 512 are fixedly connected to the protective plate 54 and the inclined plate 513 respectively.

The inclined plate 513 is located on the side of the protective plate 54 away from the installation box 1.

[0052] The bottom of the sliding bar 515 is symmetrically fixedly connected with a vertical rod 516, and the vertical rod 516 is slidably connected to the support block 514. A spring 2 517 is fixedly installed between the bottom surface of the sliding bar 515 and the top surface of the support block 514. There are no less than three springs 2 517.

[0054] Example 1: Figures 4-10As shown, the downward inclination angle of the rain shield 3 is greater than five degrees, which is convenient for diverting rainwater. When the two sides of the device are hit or blown by the wind, the protective plate 54 is impacted, and the protective plate 54 slides on the cross bar 53 and compresses the spring 55. The protective plate 54 drives the rotating member 57 to move. Through the cooperation of the inclined rod 58, the connecting block 59 and the sliding seat 510, the sliding seat 510 slides inside the spiral groove 56. The roller 511 is used to assist the smooth sliding of the sliding seat 510. The sliding seat 510 drives the connecting block 59 and the inclined rod 58 to move. Since the rotating member 57 and the protective plate 54 are rotatably installed, the connecting block 59 and the roller 511 are rotatably installed, so that the trajectory of the sliding seat 510 and the connecting block 59 is spirally expanded outward, thereby adapting to the approach of the protective plate 54 to the vertical plate 52, and the external buffer is slowed down by the spring 55 to reduce the damage to the installation box 1.

[0055] When the impacted protective plate 54 moves, it will also drive the sliding rod 512 to slide inside the other protective plate 54, and the inclined plate 513 will slide on the top of the side plate 51, thereby improving the support stability of the side that is not impacted, making it easier to improve the overall support stability of the installation box 1 and reduce the situation where the installation box 1 is blown over by the wind.

[0056] The movement of the sliding rod 512 will also drive the push bar 519 to move. The push bar 519 squeezes the inclined surface of the inverted trapezoidal block 520, causing the inverted trapezoidal block 520 to rise, and the inverted trapezoidal block 520 drives the sliding bar 515 to rise. The sliding bar 515 drives the vertical rod 516 to slide inside the support block 514, and the sliding bar 515 will stretch the spring 2 517, so that the top of the sliding bar 515 is pressed against the bottom surface of the sealing door 4, thereby improving the closing sealing of the sealing door 4, solving the problem of the inconvenience of combining the anti-collision protection and windproof protection of the box-type substation, affecting the normal operation of the box-type substation in a high wind speed environment, and reducing the working reliability and service life of the substation.

[0057] A sealing assembly 6 is provided on the upper part of one side of the installation box 1 close to the sealing door 4. The sealing assembly 6 includes a clearance groove 61 opened on the upper part of the outer side of the sealing door 4. The clearance groove 61 is located on the side of the sealing door 4 close to the installation box 1. A blocking bar portion 62 is fixedly connected to the upper part of the side of the installation box 1 close to the sealing door 4.

[0058] The blocking strip portion 62 is continuously bent, and the number of bends of the blocking strip portion 62 is greater than three times. A sealing strip portion 63 is fixedly connected to a side of the blocking strip portion 62 close to the sealing door 4 .

[0059] The bent portion of the blocking strip portion 62 is located inside the clearance groove 61 , the sealing door 4 is in contact with the sealing strip portion 63 , and water seepage holes 64 are symmetrically provided on the bottom surface of the blocking strip portion 62 .

[0060] Example 2: Figure 11-13As shown, the retaining bar portion 62 is a continuous bending structure with more than three bends and a bending angle of ninety degrees. The flow path of water or other liquids is extended through multiple curved channels, thereby increasing the water blocking effect. A seepage hole 64 is provided on the inner bottom surface of the continuous bending structure, so that even if water seeps in, it can be quickly discharged from the seepage hole 64 to avoid water accumulation.

[0061] The baffle portion 62 increases the installation stability and has a water-guiding effect. When rainwater or other liquids come into contact with the baffle portion 62, the baffle portion 62 folds upward, and the liquid will flow along the baffle portion 62 to the seepage hole 64 and be discharged from the seepage hole 64. The sealing strip portion 63 is made of EPDM rubber. When the sealing door 4 is closed, the sealing strip portion 63 can fit tightly on the top surface of the sealing door 4, forming a reliable sealing barrier, effectively preventing rainwater, dust and foreign matter from invading from the top of the sealing door 4.

[0062] Working principle: When using this device, first, Figures 1-13 As shown, when both sides of the device are hit or blown by wind, the protective plate 54 is impacted, and the protective plate 54 slides on the cross bar 53 and compresses the spring 1 55, so that the sliding seat 510 and the connecting block 59 spiral outward, and the spring 1 55 slows down the external buffer, thereby reducing the damage to the installation box 1. When the impacted protective plate 54 moves, it also drives the sliding rod 512 to slide inside the other protective plate 54, and the inclined plate 513 slides on the top of the side plate 51. The movement of the sliding rod 512 also drives the push bar 519 to move, and the push bar 519 squeezes the inverted trapezoidal block 5 The inclined surface 20 makes the inverted trapezoidal block 520 rise, and the top of the sliding bar 515 presses against the bottom surface of the sealing door 4, thereby improving the closing sealing of the sealing door 4. The rain shield 3 is used to divert rainwater, and the retaining bar portion 62 is a continuous bending structure. Through multiple curved channels, the flow path of water or other liquids is extended, thereby increasing the water blocking effect. The seepage hole 64 is used to discharge accumulated water. When the sealing door 4 is closed, the sealing strip portion 63 can fit tightly on the top surface of the sealing door 4 to form a reliable sealing barrier, effectively preventing rainwater, dust and foreign matter from invading from the top of the sealing door 4.
