Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet with a flexible rain shield. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits.

[0003] In the existing technology, the rain cover of the existing power distribution cabinet is fixed to the top of the power distribution cabinet as an integral part, while the cooling fan and ventilation window are set at the bottom of the power distribution cabinet. The fixed rain cover is inconvenient to provide flexible protection against falling solid objects and is prone to vibration and damage to the electrical components inside the power distribution cabinet. Secondly, the ventilation window can only provide one-way ventilation, which is inefficient for heat dissipation of electrical components. Moreover, when it rains, rainwater and moisture can easily enter, causing corrosion and short circuits to the electrical components. Summary of the Invention

[0021] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0022] See Figures 1-6 This invention provides a power distribution cabinet with a flexible rain shield, comprising a main cabinet 1, a rain shield 2, and a first ventilation window 11. The rain shield 2 is positioned above the main cabinet 1, and a guide rod 3 is inserted into the top of the main cabinet 1. The upper end of the guide rod 3 is fixedly connected to the rain shield 2, while the lower end passes downward through a first connecting plate 31 and is fixedly connected to a second connecting plate 32. A return spring 5 is also sleeved on the guide rod 3, and the return spring 5 is positioned between the first connecting plate 31 and the second connecting plate 32. A connecting pipe 7 is also fixedly connected to the first connecting plate 31, with the lower end of the connecting pipe 7 fixedly connected to a hollow plate 8 and the upper end sleeved on the lower part of a U-shaped ventilation pipe 4. U-shaped ventilation duct 4 is fixedly installed at the top inner position of the main cabinet 1, and an air inlet is provided at the upper middle part of the U-shaped ventilation duct 4. A fourth connecting plate 71 is also sleeved and fixed on the connecting pipe 7. The upper end of the fourth connecting plate 71 contacts the telescopic rod on the lower side of the electric cylinder 6. The upper end of the electric cylinder 6 is fixedly connected to the third connecting plate 61. The third connecting plate 61 is fixedly installed on the side wall of the main cabinet 1. The first ventilation window 11 is installed at the lower side of the main cabinet 1, and a cooling fan 9 is correspondingly provided on the inner side of the first ventilation window 11. The cooling fan 9 is fixedly installed at the bottom inner position of the main cabinet 1, and a gap is left between the cooling fan 9 and the first ventilation window 11 for the hollow plate 8 to extend into.

[0023] A ventilation opening is provided in the middle of the upper side of the main cabinet 1. A second ventilation window 12 and a moisture-absorbing cotton 13 are installed inside the ventilation opening. The moisture-absorbing cotton 13 is located on the upper side of the second ventilation window 12, thereby filtering and dehumidifying the passing air.

[0024] The air inlet is located on the lower side of the ventilation opening. The U-shaped ventilation pipe 4 is fixed to the inner top of the main cabinet 1 by a fixing seat, so that air can be sent into the U-shaped ventilation pipe 4 through the ventilation opening and the air inlet.

[0025] A third ventilation window 81 is installed on the inner side of the hollow panel 8 to facilitate ventilation of the hollow panel 8.

[0026] The second connecting plate 32 is fixedly installed on the inner side wall of the main cabinet 1, and a through hole is provided on the second connecting plate 32. The lower part of the guide rod 3 passes through the through hole and is connected to the snap ring. The snap ring is located on the lower side of the second connecting plate 32, so that the guide rod 3 can move down along the second connecting plate 32, which can simultaneously drive the first connecting plate 31 to move down, thereby compressing the reset spring 5. The snap ring can limit the reset of the guide rod 3.

[0027] It also includes a rain sensor, a temperature and humidity sensor, and a control terminal. The rain sensor is installed on the top of the rain cover 2, and the temperature and humidity sensor and the control terminal are installed inside the main cabinet 1. The control terminal is electrically connected to the rain sensor, the temperature and humidity sensor, the electric cylinder 6 and the cooling fan 9 through wires. The rain sensor is a capacitive rain sensor, which can monitor the rain situation in real time. The temperature and humidity sensor can detect the temperature and humidity inside the main cabinet 1.

[0028] During use, this invention uses a rain sensor to detect whether it is raining and a temperature and humidity sensor to detect the temperature and humidity inside the distribution cabinet. When the rain sensor detects rain, it transmits the detection signal to the control terminal, which then controls the electric cylinder 6 to move. The electric cylinder 6 moves and moves the fourth connecting plate 71 downward. The downward movement of the fourth connecting plate 71 simultaneously moves the hollow plate 8, the connecting pipe 7, and the first connecting plate 31 downward, so that the hollow plate 8 extends between the cooling fan 9 and the first ventilation window 11. At the same time, the downward movement of the first connecting plate 31 moves the rain cover 2 downward, so that the rain cover 2 covers the ventilation opening at the top of the main cabinet 1, preventing rainwater from entering the main cabinet 1 through the ventilation opening. The downward movement of the hollow plate 8 can also block the first ventilation window 11, preventing rainwater from entering the main cabinet 1 through the first ventilation window 11. When a solid object falls onto the rain cover 2, it can cause the rain cover 2 to move downwards, and drive the guide rod 3 to move downwards along the second connecting plate 32. Simultaneously, it can drive the first connecting plate 31 to move, which can compress the return spring 5. Under the rebound force of the return spring 5, the solid object is damped. By damping the solid object, the electrical components inside the main cabinet 1 can be protected, avoiding vibration and damage to the electrical components. On sunny days, the cooling fan 9 can be run directly to dissipate heat from the electrical components inside the main cabinet 1. When it rains or the temperature and humidity sensor detects that the humidity inside the main cabinet 1 has reached the set value, the hollow board 8 is moved between the cooling fan 9 and the first ventilation window 11. The operation of the cooling fan 9 can drive the airflow, allowing the air inside the hollow board 8 to pass through the third ventilation window 81 and be blown by the cooling fan 9 to dissipate heat from the electrical components inside the main cabinet 1. The negative pressure generated inside the hollow board 8 can then send air into the air inlet through the vent at the top of the main cabinet 1, and then into the hollow board 8 through the U-shaped ventilation pipe 4 and the connecting pipe 7, facilitating air circulation. The air passes through the moisture-absorbing cotton 13 and the second ventilation window 12, which can dehumidify and filter the air, thus preventing moisture from entering when the cooling fan 9 is dissipating heat from the electrical components.

[0029] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
