Technical Field

[0001] The invention belongs to the technical field of transformer substations, in particular to a ventilation structure of a prefabricated cabin of a transformer substation. Background Art

[0002] The prefabricated substation cabin is a new type of substation construction method. Electrical equipment such as transformers, high-voltage circuit breakers, disconnectors, low-voltage circuit breakers, current transformers, and voltage transformers are installed inside the cabin. The prefabricated substation cabin can be manufactured, assembled, wired, and debugged in the factory and transported to the project site as a whole, which greatly shortens the construction period.

[0003] A Chinese patent with announcement number CN117175368B discloses a ventilation structure for a prefabricated cabin in a substation, including an exhaust heat dissipation component, an air supply and cooling component, a ventilation intelligent controller, and an air intake ventilation component. When the temperature inside the prefabricated cabin is high and the ambient humidity is high, the ventilation intelligent controller will control the exhaust heat dissipation component and the air supply and cooling component to ventilate and dissipate heat inside the cabin. The exhaust heat dissipation component can exhaust part of the hot air in the cabin to the outside of the cabin, and the air supply and cooling component can supply low-temperature air into the cabin, thereby effectively dissipating and cooling the prefabricated cabin to prevent damage to the electrical equipment in the cabin due to excessive temperature. During the entire ventilation and heat dissipation process, the cabin can remain in a sealed state, and no air from the external environment will enter the cabin. Even if the environment is harsh, the humid air, wind, sand, and dust in the external environment cannot affect the electrical equipment in the cabin, which makes up for the shortcomings of the existing ventilation structure and improves safety and practicality.

[0029] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Embodiment 1

[0031] As attached Figure 1 To Attachment Figure 4 As shown, the present invention provides a ventilation structure of a prefabricated cabin of a substation, including a prefabricated cabin body 1, the prefabricated cabin body 1 is connected to an exhaust pipe 2, wherein the prefabricated cabin body 1 dissipates heat through the exhaust pipe 2, the exhaust pipe 2 is connected to an opening and closing component 3, wherein the opening and closing component 3 is used to control whether the exhaust pipe 2 can pass air, when the opening and closing component 3 is opened, the exhaust pipe 2 can discharge hot air for heat dissipation, when the opening and closing component 3 is closed, it is prevented that the wind and sand dust from the outside enters the prefabricated cabin body 1 and affects the service life of the equipment, a plurality of opening and closing components 3 are connected to a synchronization component 4, wherein the synchronization component 4 is used to control the synchronous rotation of a plurality of opening and closing components 3, and then control whether the exhaust pipe 2 is connected to the outside, the synchronization component 4 is connected to a driving component 5, wherein the driving component 5 is used to drive the synchronization component 4 to work, and the exhaust pipe 2 is provided with a dustproof component 6, wherein the dustproof component 6 is used to prevent dust from entering the interior of the prefabricated cabin body 1 through the exhaust pipe 2;

[0032] The opening and closing assembly 3 includes a support column 301, which is rotatably connected to a first center rod 302, and the first center rod 302 is fixedly connected to an opening and closing leaf 303. When a plurality of opening and closing leaves 303 are in a horizontal state, the exhaust pipe 2 can be blocked. When a plurality of opening and closing leaves 303 are in a vertical state, the exhaust pipe 2 can circulate air normally. The opening and closing leaf 303 is connected to a second center rod 304. The opening and closing leaf 303 rotates around the first center rod 302 and the second center rod 304. The second center rod 304 passes through the exhaust pipe 2. The opening and closing leaf 303 is rotated by operating the portion of the second center rod 304 extending outside the exhaust pipe 2.

[0033] As can be seen from the above, the driving component 5 drives the synchronization component 4 to work, the synchronization component 4 causes the multiple second center rods 304 to rotate, and the second center rods 304 drive the opening and closing pages 303 to rotate. When the multiple opening and closing pages 303 are rotated to a horizontal state, the exhaust pipe 2 can be blocked to prevent dust from falling into the prefabricated cabin 1 and affecting the service life of the equipment. When the multiple opening and closing pages 303 are rotated to a vertical state, the exhaust pipe 2 can circulate air normally to dissipate heat in the prefabricated cabin 1. The dustproof component 6 can prevent dust from falling on the surface of the opening and closing pages 303, thereby preventing the opening and closing pages 303 from shaking off dust into the prefabricated cabin 1 when the opening and closing pages 303 rotate.

[0034] Embodiment 2

[0035] As attached Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that it further includes a support rod 305, and the support rod 305 is an "L"-shaped rod. The vertical rod of the support rod 305 is fixedly connected to the support column 301, and the horizontal rod of the support rod 305 is fixedly connected to the inner wall of the exhaust pipe 2. By setting the support rod 305, the support column 301 is fixed, thereby providing support for the first center rod 302 and the opening and closing leaf 303.

[0036] As attached Figure 4 As shown, specifically, the synchronization component 4 includes a swinging plate 401 fixedly connected to the second center rod 304, wherein the swinging plate 401 and the second center rod 304 will rotate synchronously, the swinging plate 401 is provided with a swinging groove 402, the swinging plate 401 is provided with a swinging groove 402 for the movement of a synchronization rod 403, the swinging groove 402 is movably connected to the synchronization rod 403, the synchronization rod 403 is fixedly connected to a synchronization ring 404, when the synchronization ring 404 rotates, it will drive the synchronization rod 403 to rotate together, the rotating synchronization rod 403 moves in the swinging groove 402, and drives the swinging plate 401 to rotate.

[0037] As attached Figure 4 As shown, further, the synchronization component 4 also includes a support frame 405, and the support frame 405 is slidably connected with the synchronization ring 404, wherein the support frame 405 provides support for the synchronization ring 404, and a plurality of balls are provided on the contact surface between the support frame 405 and the synchronization ring 404. By providing rolling balls, the friction between the support frame 405 and the synchronization ring 404 is reduced, so that the rotation of the synchronization ring 404 is smoother.

[0038] As attached Figure 4As shown, further, the drive assembly 5 includes an extension plate 501 fixedly connected to the synchronous ring 404, and the extension plate 501 is fixedly connected to the extension rod 502. The extension plate 501 and the extension rod 502 are arranged to avoid the first transmission plate 503 and the second transmission plate 504 from interfering with the movement of other parts. The extension rod 502 is rotatably connected to the first transmission plate 503, and the first transmission plate 503 is rotatably connected to the second transmission plate 504. The second transmission plate 504 is fixedly connected to the driving motor 505. When the driving motor 505 rotates, the total length of the second transmission plate 504 and the first transmission plate 503 changes, which drives the extension plate 501 to rotate, and then drives the synchronous ring 404 to rotate.

[0039] As attached Figure 4 As shown, further, the driving assembly 5 also includes a mounting plate 506 , and the driving motor 505 is fixed on the mounting plate 506 , and the mounting plate 506 provides support for the driving motor 505 .

[0040] As can be seen from the above, the driving motor 505 drives the second transmission plate 504 to rotate, and the second transmission plate 504 pulls the first transmission plate 503. As the second transmission plate 504 rotates, the total length of the second transmission plate 504 and the first transmission plate 503 changes cyclically, thereby driving the extension rod 502 to rotate back and forth. The extension rod 502 drives the synchronous ring 404 to rotate back and forth through the extension plate 501. When the synchronous ring 404 rotates, it drives the synchronous rod 403 to rotate together. Since the synchronous rod 403 moves in the swing groove 402, the synchronous rod 403 will move the swing plate 401. At this time, the swing plate 401 will drive the second center rod 304 to rotate, and then drive the multiple opening and closing pages 303 to rotate. Whether the exhaust pipe 2 is ventilated is controlled according to the rotation direction of the synchronous ring 404, so as to achieve the purpose of synchronous rotation of multiple opening and closing pages 303, and speed up the adjustment of whether the exhaust pipe 2 is ventilated.

[0041] Embodiment 3

[0042] As attached Figure 5 To Attachment Figure 6 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the dustproof component 6 includes a dustproof net 601 connected to the exhaust pipe 2, wherein the dustproof net 601 can intercept dust in the air to prevent dust from falling on the opening and closing leaf 303, and an elastic rope 602 is fixedly connected to the upper surface of the dustproof net 601, and the elastic rope 602 is fixedly connected to a wind shield 603. The air blows up the wind shield 603, and the wind shield 603 pulls the dustproof net 601 through the elastic rope 602, causing the dustproof net 601 to vibrate and shake off the dust on the surface of the dustproof net 601, and an exhaust fan 604 is fixedly installed on the inner wall of the exhaust pipe 2, and the exhaust fan 604 accelerates the air flow rate, thereby improving the heat dissipation efficiency.

[0043] As attached Figure 5 To Attachment Figure 6 As shown, specifically, the dustproof component 6 also includes a mounting groove 605 opened at the upper end of the exhaust pipe 2, and a spring 606 is arranged in the mounting groove 605. When the air blows up the wind shield 603, the dustproof net 601 vibrates due to the impact of the airflow and the traction of the wind shield 603, and the spring 606 will amplify the vibration. The spring 606 is fixedly connected to the dustproof net 601.

[0044] As attached Figure 5 To Attachment Figure 6 As shown, further, the dustproof component 6 also includes a blocking rod 607 fixedly connected to the inner wall of the exhaust pipe 2, wherein the blocking rod 607 makes the diverter block 608 located in the middle of the airflow, and the blocking rod 607 is fixedly connected with a plurality of diverter blocks 608, which change the direction of the airflow, destroy the stability of the airflow, induce turbulence, and thus make the wind shield 603 shake, make the traction of the wind shield 603 disordered, and make the vibration of the dustproof net 601 more violent.

[0045] As attached Figure 5 To Attachment Figure 6 As shown, further, a slope is provided at the upper end of the exhaust pipe 2, and the dustproof net 601 is located on the slope of the exhaust pipe 2. The slope makes the dustproof net 601 tilted to facilitate dust to slide off the dustproof net 601, and the blocking rod 607 is spirally arranged upward to enhance the influence of the diverter block 608 on the airflow.

[0046] As can be seen from the above, the dustproof net 601 intercepts dust in the air and prevents dust from falling on the horizontal opening and closing page 303, and prevents dust from falling from the opening and closing page 303 into the prefabricated cabin 1 when the opening and closing page 303 is turned into a vertical state. When the exhaust pipe 2 can circulate air, the air is affected by the diversion block 608 and turbulence occurs. The air impacts the dustproof net 601 and the wind shield 603, causing the dustproof net 601 to vibrate. The dust on the dustproof net 601 slides down due to the vibration, thereby preventing the dust from blocking the dustproof net 601. At the same time, the exhaust fan 604 makes the air flow upward to prevent dust from falling into the exhaust pipe 2 due to vibration, and the exhaust fan 604 accelerates the air flow to improve the heat dissipation efficiency.
