Description

Technical Field

[0001] The present invention relates to the technical field of substations, and particularly to a box-type substation with a protection structure. Background Art

[0002] A box-type substation is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device, which are prefabricated in a factory and arranged in a compact indoor or outdoor distribution equipment according to a certain wiring scheme. Existing box-type substations with high protection levels (such as IP44): The shell has strong sealing performance, excellent dust and water protection capabilities, but the ventilation path is restricted, the natural heat dissipation efficiency is low, and it is easy to cause the internal temperature rise to exceed the standard. While box-type substations with low protection levels (such as IP33): The shell can be designed with ventilation holes, louvers and other structures, and the heat dissipation capacity is improved, but dust and rainwater are easy to enter, which may cause problems such as flashover and corrosion of equipment.

[0003] For example, an outdoor box-type substation with a protection structure with the publication number CN221669406U includes a box body. A base is fixedly connected to the bottom of the box body. A cavity is opened inside the base. The center of the bottom of the inner wall of the cavity is rotatably connected to a threaded rod. The upper end of the threaded rod is rotatably connected to the top of the inner wall of the cavity. A first bevel gear is fixedly connected to the outer wall of the upper end of the threaded rod. A second bevel gear is meshed and connected to one side of the first bevel gear. A rotating shaft is fixedly connected to one side of the second bevel gear; for this kind of outdoor box-type substation with a protection structure, turning the handle can drive the rotating shaft to rotate, thereby driving the threaded rod to rotate. While the threaded rod rotates, the moving plate can drive the universal wheel to move downward. When the universal wheel extends out of the base, the box body can be easily transported. Through the buffer assembly arranged between the moving plate and the universal wheel, the stability of the substation during movement can be higher, thereby playing a better protective role for the substation. However, since the box-type substation is designed for installation in an open environment and must be able to withstand different weather conditions, for outdoor box-type substations, while anti-collision protection is required, appropriate wind prevention measures should also be taken to ensure the normal operation of the box-type substation in a high-wind environment, avoid equipment damage or safety accidents caused by strong winds, improve the working reliability and service life of the substation, and for the connection between the box door and the door frame, corresponding sealing protection should also be set to reduce foreign objects from splashing into the interior of the substation, thereby ensuring the normal operation of the equipment inside the box body of the substation.

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

[0029] There are no less than four sealing doors 4. A hinge part 7 is evenly and fixedly installed on one side of the sealing door 4. The sealing door 4 is hinged and fixed to the installation box body 1 through the hinge part 7. The side plates 51 are symmetrically and fixedly installed on both sides of the bottom plate 2. There are no less than two cross bars 53. One end of the first spring 55 is fixedly connected to the vertical plate 52, and the other end of the first spring 55 is fixedly connected to the protection plate 54.

[0030] A spiral groove 56 is opened in the middle of the side of the vertical plate 52 close to the installation box body 1. One end of the inclined rod 58 is hinged with a rotating part 57. The rotating part 57 is rotatably connected to the protection plate 54. The other end of the inclined rod 58 is hinged with a connecting block 59. The connecting block 59 is rotatably connected to a sliding seat 510. The sliding seat 510 is slidably connected to the spiral groove 56. The inclined rod 58 rotates along the Y-axis direction, and the rotating part 57 and the connecting block 59 rotate along the X-axis direction. The cross section of the spiral groove 56 is convex-shaped to prevent the sliding seat 510 from coming out. Rollers 511 are symmetrically and fixedly installed on the outside of the sliding seat 510. The rollers 511 are in rolling connection with the spiral groove 56.

[0031] The pressing part includes support blocks 514 respectively fixedly installed on one side of the front and back of the bottom plate 2. The lower part of the side of the protection plate 54 close to the installation box body 1 is connected with a sliding rod 512. A sliding strip 515 is sleeved on the outside of the sliding rod 512. The sliding strip 515 is slidably installed on the support block 514. The sliding strip 515 is located directly below the sealing door 4.

[0032] The support 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 plate 51. Both ends of the sliding rod 512 are fixedly connected to the protection plate 54 and the inclined plate 513 respectively. The front sliding rod 512 is slidably connected to the left protection plate 54, and the rear sliding rod 512 is slidably connected to the right protection plate 54. The inclined plate 513 is located on the side of the protection plate 54 away from the installation box body 1.

[0033] Vertically rods 516 are symmetrically and fixedly connected to the bottom of the sliding bar 515. The vertically rods 516 are slidably connected to the support blocks 514. A second spring 517 is fixedly installed between the bottom surface of the sliding bar 515 and the top surface of the support blocks 514, and the number of the second springs 517 is not less than three.

[0034] A chute 518 is formed inside the sliding bar 515. The sliding rod 512 is slidably connected to the chute 518. A push bar 519 is fixedly connected to the top of the sliding rod 512. An inverted trapezoidal block 520 is fixedly connected to the inner top surface of the chute 518. The number of the push bars 519 is not less than three. The number of the inverted trapezoidal blocks 520 is the same as that of the push bars 519, and the inverted trapezoidal blocks 520 and the push bars 519 are arranged at intervals. The push bars 519 are in contact with the inverted trapezoidal blocks 520.

[0035] Example 1: As Figures 4 - 10 shown, the downward inclination angle of the rain shield 3 is greater than five degrees, which is convenient for guiding rainwater. When the two sides of the device are impacted or blown by wind, the protection plate 54 is impacted. The protection plate 54 slides on the cross bar 53 and compresses the first spring 55. The protection plate 54 drives the rotating part 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 stable 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 part 57 is rotatably installed on the protection plate 54 and the connecting block 59 is rotatably installed on the roller 511, the trajectories of the sliding seat 510 and the connecting block 59 are spirally unfolded outward, so as to adapt to the approach of the protection plate 54 to the vertical plate 52. The external impact is buffered by the first spring 55 to reduce the damage to the installation box body 1.

[0036] When the impacted protection plate 54 moves, it will also drive the sliding rod 512 to slide inside the other protection plate 54, and the inclined plate 513 slides on the top of the side plate 51, so as to improve the support stability of the unimpacted side, facilitate improving the overall support stability of the installation box body 1, and reduce the situation that the installation box body 1 is toppled by wind.

[0037] 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 wind 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.

[0038] 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 strip portion 62 is fixedly connected to the upper part of the side of the installation box 1 close to the sealing door 4.

[0039] 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 one side of the blocking strip portion 62 close to the sealing door 4 .

[0040] 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 .

[0041] Embodiment 2: Figures 11 - 13 As shown, the retaining bar portion 62 is a continuous bending structure, the number of bends is greater than three times, and the bending angle is ninety degrees. Through multiple curved channels, the flow path of water or other liquids is extended, thereby increasing the water blocking effect. The inner bottom surface of the continuous bending structure is provided with a seepage hole 64, so that even if water seeps in, it can be quickly discharged from the seepage hole 64 to avoid water accumulation.

[0042] The baffle portion 62 increases the installation stability and has a water-guiding effect. When rainwater or other liquid contacts the baffle portion 62, the liquid will flow along the baffle portion 62 to the seepage hole 64 due to the upward folding of the baffle portion 62, 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 to form a reliable sealing barrier, effectively preventing rainwater, dust and foreign matter from invading from the top of the sealing door 4.

[0043] Working principle: When using the device, first, Figures 1 - 13As shown, when the two sides of the device are impacted or blown by the wind, the protection plate 54 is impacted. The protection plate 54 slides on the cross bar 53 and compresses the first spring 55, causing the sliding seat 510 and the connecting block 59 to spiral outwards. Through the buffering of the first spring 55 to the outside, the damage to the installation box body 1 is reduced. When the impacted protection plate 54 moves, it will also drive the sliding rod 512 to slide inside another protection plate 54, and the inclined plate 513 slides on the top of the side plate 51. 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. The top of the sliding strip 515 abuts against the bottom surface of the sealing door 4, improving the closing tightness of the sealing door 4. The rain baffle 3 is used to divert rainwater. The rain baffle part 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 water seepage hole 64 is used to drain accumulated water. When the sealing door 4 is closed, the sealing strip part 63 can closely fit on the top surface of the sealing door 4, forming a reliable sealing barrier, effectively preventing rainwater, dust, and foreign objects from invading from the top of the sealing door 4.
