Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically an improved structure for a prefabricated substation ventilation top cover. Background Technology

[0002] Prefabricated substations, also known as box-type substations, are a type of high-voltage switchgear, distribution transformer, and low-voltage distribution equipment. They are particularly suitable for urban power grid construction and renovation, and represent a new type of substation that has emerged after civil engineering substations. Box-type substations are mostly used for outdoor installation, which requires the enclosure to have certain weather resistance requirements.

[0003] The utility model patent with authorization announcement number CN202422990026.7 discloses a ventilation top cover structure for a box-type substation. By setting up a top plate, bottom plate, triangular side plate, air outlet one, air outlet two, ventilation opening, fan, filter one, filter two, and air outlet channel, it solves the problems of no ventilation structure on the top cover of the box-type substation, poor heat dissipation effect, the need for sufficient weather resistance when ventilating the top cover, and poor heat insulation effect of the top cover.

[0004] However, because static electricity can easily accumulate in the electromagnetic field inside a substation, it may cause an electric arc accident. The aforementioned ventilation cover structure lacks a static electricity elimination mechanism, posing a safety hazard. The ventilation design of the above scheme introduces a fan to accelerate heat dissipation, but the ventilation opening is often in an open state, causing dust, sand and other pollutants to enter the enclosure and affect the normal operation of the equipment. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an improved structure for the ventilation top cover of a box-type substation to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] The ventilation mechanism includes a ventilation shell fixedly connected to the inner wall of the ventilation pipe. Multiple rotating shafts are rotatably connected to the inner wall of the ventilation shell. A ventilation plate is fixedly connected to the surface of the rotating shaft. An arc-shaped guide plate is installed on the surface of the ventilation shell. A moving rod is slidably connected to the surface of the arc-shaped guide plate along the arc. A connecting plate is rotatably connected to the surface of the moving rod. Multiple connecting rods are rotatably connected to the surface of the connecting plate, and the multiple connecting rods are respectively fixedly connected to the surface of the multiple rotating shafts.

[0009] Preferably, the protective plate and the ventilation pipe are both inclined from the inside to the outside, and one end of the ventilation pipe extends to the outside of the top cover body.

[0011] Preferably, a support frame is installed inside the top cover body, a reinforcing rod is installed on the surface of the support frame, and the protective plate is fixedly connected to the surface of the reinforcing rod.

[0012] Preferably, the ventilation shell is inclinedly disposed on the inner wall of the ventilation pipe, and the cross-section of the ventilation plate is rhomboid.

[0013] Preferably, a threaded rod is rotatably connected to the surface of the ventilation shell, and an internal threaded plate is threadedly connected to the surface of the threaded rod, with the moving rod slidably connected to the surface of the internal threaded plate.

[0014] Preferably, a servo motor is mounted on the surface of the ventilation housing, and the output shaft of the servo motor is fixedly connected to one end of the threaded rod.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model moves a movable rod on the surface of an arc-shaped guide plate.

[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-5 An improved structure for a ventilation top cover of a box-type substation includes a top cover body 1, two protective plates 2 on the upper surface of the top cover body 1, two ventilation pipes 3 installed on the surface of the protective plates 2, a dustproof net 4 installed on the outer opening of the ventilation pipes 3, a ventilation mechanism 5 installed inside the ventilation pipes 3, and an anti-static fan 6 installed inside the protective plates 2.

[0026] The ventilation mechanism 5 includes a ventilation shell 501 fixedly connected to the inner wall of the ventilation pipe 3. Multiple rotating shafts 510 are rotatably connected to the inner wall of the ventilation shell 501. A ventilation plate 502 is fixedly connected to the surface of the rotating shaft 510. An arc-shaped guide plate 505 is installed on the surface of the ventilation shell 501. A moving rod 506 is slidably connected to the surface of the arc-shaped guide plate 505 along the arc. A connecting plate 507 is rotatably connected to the surface of the moving rod 506. Multiple connecting rods 508 are rotatably connected to the surface of the connecting plate 507, and the multiple connecting rods 508 are respectively fixedly connected to the surface of the multiple rotating shafts 510. The model of the antistatic fan 6 is 410CFM.

[0027] Through the above technical solution, the moving rod 506 moves on the surface of the arc-shaped guide plate 505. At this time, under the action of the connecting plate 507 and the connecting rod 508, the rotating shaft 510 and the ventilation plate 502 are driven to rotate, thereby opening or closing the interior of the ventilation pipe 3. Through the setting of the protective plate 2 and the ventilation pipe 3, rainwater can be prevented from seeping in. At the same time, the dustproof net 4 can reduce the probability of external dust entering. Meanwhile, the antistatic fan 6 can be treated with antistatic agents to reduce the risk of electric arc and improve safety.

[0028] Both the protective plate 2 and the ventilation pipe 3 are inclined from the inside out. One end of the ventilation pipe 3 extends to the outside of the top cover body 1. The inclined arrangement of the protective plate 2 and the ventilation pipe 3 facilitates the falling of rainwater on the surface of the protective plate 2 and the ventilation pipe 3, and the rainwater will not enter the top cover body 1 through the outer end of the ventilation pipe 3.

[0029] Both sides of the upper surface of the protective plate 2 are equipped with hanging plates 7, and the surface of the hanging plates 7 is provided with hanging holes. The setting of the hanging plates 7 and the hanging holes makes it easy to move the protective plate 2, thereby bringing convenience to the staff.

[0030] The top cover body 1 is equipped with a support frame 8 inside, and a reinforcing rod 9 is installed on the surface of the support frame 8. The protective plate 2 is fixedly connected to the surface of the reinforcing rod 9. Through the setting of the support frame 8 and the reinforcing rod 9, the top cover body 1 and the protective plate 2 can be supported and reinforced, thereby increasing the strength of the top cover structure.

[0031] The ventilation shell 501 is inclinedly installed on the inner wall of the ventilation pipe 3, and the cross-section of the ventilation plate 502 is rhomboid. The inclined installation of the ventilation shell 501 facilitates the falling of rainwater inside the ventilation shell 501. The shape of the ventilation plate 502 facilitates the closing and opening of the inner wall of the ventilation shell 501.

[0032] A threaded rod 503 is rotatably connected to the surface of the ventilation housing 501. An internal threaded plate 504 is threadedly connected to the surface of the threaded rod 503, and a moving rod 506 is slidably connected to the surface of the internal threaded plate 504. A servo motor 509 is mounted on the surface of the ventilation housing 501, and the output shaft of the servo motor 509 is fixedly connected to one end of the threaded rod 503. The servo motor 509 starts its output shaft to drive the threaded rod 503 to rotate. The rotation of the threaded rod 503 drives the internal threaded plate 504 to move. At this time, the moving rod 506 will move on the surface of the internal threaded plate 504.

[0033] When in use, the servo motor 509 is activated when heat dissipation is required inside the top cover body 1. The output shaft of the servo motor 509 drives the threaded rod 503 to rotate. The rotation of the threaded rod 503 drives the inner threaded plate 504 to move. At this time, the moving rod 506 moves on the surface of the inner threaded plate 504 and the surface of the arc-shaped guide plate 505. Under the action of the connecting plate 507 and the connecting rod 508, the rotating shaft 510 and the ventilation plate 502 are driven to rotate, thereby opening or closing the interior of the ventilation pipe 3. The protective plate 2 and the ventilation pipe 3 can prevent rainwater from seeping in, while the dustproof net 4 can reduce the probability of external dust entering. At the same time, the antistatic fan 6 blows air from the inside of the top cover body 1 to the outside of the ventilation pipe 3 and removes static electricity from the inside of the top cover body 1.

[0034] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
