[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In this solution, in strong wind weather with wind force greater than level 5 or rainy and snowy weather, the low-speed motor is powered off and stops operating. The output end of the electric push rod contracts to pull the pawl away from the ratchet wheel, releasing the locking engagement between the pawl and the ratchet wheel, so that the cabinet body, the cabinet door, the tail wing and the two side wings can deflect. The tail wing uses the wind pressure to push the cabinet body, the cabinet door, the tail wing and the two side wings to deflect. The cabinet body, the cabinet door, the tail wing and the two side wings deflect automatically, so that the cabinet body makes the cabinet door face away from the wind, avoiding rain and snow from penetrating into the cabinet through the gap between the door groove and the cabinet door and damaging the electrical components. At the same time, it also avoids the overall freezing of the cabinet body and the outer surface of the cabinet door by freezing rain in extreme rainy and snowy weather, realizing the anti-freezing deflection of the intelligent high-voltage and low-voltage switchgear. By deflecting the cabinet body of the intelligent high-voltage and low-voltage switchgear, the cabinet door of the intelligent high-voltage and low-voltage switchgear is not blocked and frozen by rain and snow accumulation, eliminating the need for knocking and deicing operations, and facilitating maintenance in rainy, snowy and windy weather.

[0023] 2. In this solution, during the anti-freezing deflection process, rain and snow will flow downward from the outer surfaces of the cabinet body and the cabinet door. When the rain and snow flow to the annular flow extension plate, they are guided by the annular flow extension plate, so that the rain and snow spread and flow outside the base. The rain and snow fall around the base, avoiding freezing the deflection of the cabinet body, the cabinet door, the tail wing and the two side wings, avoiding rain and snow accumulation from interfering with the rotation of the cabinet body and the cabinet door, and preventing strong wind from blowing down the intelligent high-voltage and low-voltage switchgear.

[0024] 3. In this solution, when the electrical components in the cabinet are damaged, the low-speed motor is powered on and started. The output end of the low-speed motor drives the second driving wheel to rotate. The second driving wheel drives the second driven wheel to rotate through the transmission belt. The second driven wheel drives the cabinet body, the cabinet door, the tail wing and the two tail wings to deflect integrally through the rotating shaft, so that the door slot does not correspond to the two support columns. When the vertical angle between the tail wing and the chassis is 90 degrees, the output end of the electric push rod pushes the pawl to engage with the ratchet wheel, locking the rotation of the cabinet body, the cabinet door, the tail wing and the two tail wings. Then the stepping motor is powered on and started. The output end of the stepping motor drives the first driving gear to rotate. The first driving gear drives the shaft rod to rotate through the meshing with the first driven gear. The shaft rod drives the deflecting rod to deflect. The deflecting rod pushes and pulls the push rod. The push rod pushes the mounting rack and the cabinet door out of the door slot. At the same time, when the mounting rack and the cabinet door move, multiple sliding rods cooperate with multiple sliding grooves to horizontally and stably move the mounting rack and the cabinet door, releasing the sealing of the gap between the cabinet door and the door slot by the sealing strip. After the mounting rack and the cabinet door are pushed out of the door slot, the maintenance personnel disassemble and replace the electrical components installed on the mounting rack. Then the stepping motor is powered on and rotates in the reverse direction, so that the deflecting rod pulls the push rod, the mounting rack and the cabinet door to reset and insert into the door slot. The output end of the electric push rod contracts and pulls the pawl to release the engagement with the ratchet wheel, realizing the maintenance and replacement of the electrical components in the cabinet. By automatically opening the intelligent high and low voltage switch cabinet, the maintenance difficulty of the intelligent high and low voltage switch cabinet is reduced.

When it is necessary to restrict and lock the deflection of the cabinet body 2 and the cabinet door 5, the electric push rod 31 is energized and started. The output end of the electric push rod 31 extends to push the pawl 30 closer, realizing the engagement between the pawl 30 and the ratchet wheel 29, and locking the deflection of the cabinet body 2 and the cabinet door 5. When it is necessary to deflect the cabinet body 2 and the cabinet door 5, the electric push rod 31 is energized and started. The output end of the electric push rod 31 contracts to pull the pawl 30 away from the ratchet wheel 29, realizing the disengagement between the pawl 30 and the ratchet wheel 29, and facilitating the deflection of the cabinet body 2 and the cabinet door 5. The telescopic movement of the output end of the electric push rod 31 is used to control whether the pawl 30 engages with the ratchet wheel 29, and to control whether the cabinet body 2, the electrical components inside the cabinet body 2, and the cabinet door 5 are deflected as a whole. When performing maintenance, the overall deflection of the cabinet body 2, the electrical components inside the cabinet body 2, and the cabinet door 5 is restricted and locked by the engagement between the pawl 30 and the ratchet wheel 29, preventing the overall deflection of the cabinet body 2, the electrical components inside the cabinet body 2, and the cabinet door 5 from interfering with the maintenance of the electrical components inside the cabinet body 2.

[0059] The flow-delay component includes a sealing sleeve 36, an annular flow-delay plate 26, and an annular bottom ring 25. The sealing sleeve 36 is sleeved on the circumferential surface of the rotating shaft of the cabinet body 2, and the sealing sleeve 36 is fixedly connected to the top of the chassis 1. The annular flow-delay plate 26 is fixedly connected to the bottom of the cabinet body 2, and the annular flow-delay plate 26 is located above the chassis 1. The annular bottom ring 25 is fixedly connected to the top of the chassis 1, and the upper end of the annular bottom ring 25 extends between the inner walls of the annular flow-delay plate 26.

[0060] In the present invention, the sealing sleeve 36 is used to fill the gap between the rotating shaft of the cabinet body 2 and the chassis 1, preventing dust and moisture from entering the receiving groove 23 and corroding the electrical components in the receiving groove 23. The annular flow-delay plate 26 is used to guide rain and snow to the surrounding of the bottom of the cabinet body 2, preventing rain and snow from accumulating on the top of the chassis 1. The annular bottom ring 25 is used to block the falling rain and snow from penetrating towards the rotating shaft of the cabinet body 2. The annular bottom ring 25, in cooperation with the annular flow-delay plate 26, eliminates the accumulation of rain and snow between the chassis 1 and the cabinet body 2, preventing the accumulation of rain and snow from interfering with the rotation of the cabinet body 2 and the cabinet door 5, and preventing strong winds from blowing down the intelligent high and low voltage switchgear.

[0061] The turbulent flow component includes a tail fin 6 and two side fins 3. The two side fins 3 are fixedly connected to the outer surface of the cabinet body 2. The two side fins 3 are located on both sides of the door groove 4. The tail fin 6 is fixedly connected to the side end of the cabinet door 5, and the tail fin 6 is located between the two side fins 3.

[0062] In the present invention, two side wings 3 are used to guide rain and snow in strong winds, preventing freezing rain from freezing the gap between the door groove 4 and the cabinet door 5. The tail wing 6 uses wind pressure to push the cabinet body 2, the cabinet door 5, the tail wing 6 and the two side wings 3 to deflect, causing the cabinet body 2 and the cabinet door 5 to deflect automatically, making the cabinet door 5 face the leeward side, reducing the freezing of rain and snow in the gap between the door groove 4 and the cabinet door 5. By deflecting the cabinet body of the intelligent high and low voltage switchgear, the cabinet door of the intelligent high and low voltage switchgear is not blocked by accumulated rain and snow and frozen, eliminating the need for knocking and defrosting operations, and facilitating maintenance in rainy, snowy and windy weather.

[0063] A method for using an intelligent high and low voltage switchgear includes the following steps:

[0064] S1. Installation:

[0065] Build a 1-meter-high base on the installation ground with concrete, bricks and steel frames. Preset pipelines in the base, and the top of the steel frame extends to the top of the base. Hoist the entire empty intelligent high and low voltage switchgear onto the base, making the annular partition 27 located at the center of the top of the base, and welding the annular partition 27 to the steel bars of the base. The docking device 28 is electrically connected to the preset pipelines in the base. Start the stepping motor 19, push the mounting rack 8 and the cabinet door 5 out of the door groove 4, then install electrical components on both sides of the mounting rack 8, and finally conduct power-on debugging on the intelligent high and low voltage switchgear to complete the installation of the entire intelligent high and low voltage switchgear.

[0066] S2. No deflection:

[0067] In non-rainy and snowy weather and when the wind force is less than or equal to level 5, the low-speed motor 35 is in a power-off and shutdown state. The output end of the electric push rod 31 extends to push the pawl 30 to engage with the ratchet wheel 29, restricting the deflection of the cabinet body 2, the cabinet door 5, the tail wing 6 and the two side wings 3, and the intelligent high and low voltage switchgear does not need to deflect.

[0068] S3. Anti-freezing deflection:

[0069] In windy weather with a wind force greater than level 5 or in rainy and snowy weather, the low-speed motor 35 is in a power-off and shutdown state. The output end of the electric push rod 31 contracts to pull the pawl 30 away from the ratchet wheel 29, releasing the locking engagement between the pawl 30 and the ratchet wheel 29, enabling the cabinet body 2, the cabinet door 5, the tail wing 6 and the two side wings 3 to deflect. The tail wing 6 uses wind pressure to push the cabinet body 2, the cabinet door 5, the tail wing 6 and the two side wings 3 to deflect. The cabinet body 2, the cabinet door 5, the tail wing 6 and the two side wings 3 deflect automatically, making the cabinet body 2 position the cabinet door 5 on the leeward side, preventing rain and snow from penetrating into the cabinet body 2 through the gap between the door groove 4 and the cabinet door 5 and damaging electrical components, and also preventing freezing rain from freezing the outer surfaces of the cabinet body 2 and the cabinet door 5 as a whole in extreme rainy and snowy weather, achieving anti-freezing deflection of the intelligent high and low voltage switchgear.

[0070] S4. Rain and snow drainage:

[0071] During the anti-freezing deflection process, rain and snow will flow downward from the outer surfaces of the cabinet body 2 and the cabinet door 5. When the rain and snow flow to the annular flow guide plate 26, they are guided by the annular flow guide plate 26, causing the rain and snow to spread and flow outside the base. The rain and snow fall around the base, preventing the freezing of the deflection of the cabinet body 2, the cabinet door 5, the tail fin 6 and the two side fins 3, and realizing the drainage of rain and snow on the outer surfaces of the cabinet body 2, the cabinet door 5, the tail fin 6 and the two side fins 3.

[0072] S5. Maintenance and replacement:

[0073] When the electrical components in the cabinet body 2 are damaged, the low-speed motor 35 is powered on and started. The output end of the low-speed motor 35 drives the second driving wheel 33 to rotate. The second driving wheel 33 drives the second driven wheel 32 to rotate through the transmission belt 34. The second driven wheel 32 drives the cabinet body 2, the cabinet door 5, the tail fin 6 and the two tail fins 6 to deflect integrally through the rotating shaft, so that the door groove 4 does not correspond to the two support columns 22. When the vertical angle between the tail fin 6 and the chassis 1 is 90 degrees, the output end of the electric push rod 31 pushes the pawl 30 to engage with the ratchet wheel 29, locking the rotation of the cabinet body 2, the cabinet door 5, the tail fin 6 and the two tail fins 6. Then the stepping motor 19 is powered on and started. The output end of the stepping motor 19 drives the first driving gear 17 to rotate. The first driving gear 17 drives the shaft rod 20 to rotate through the engagement with the first driven gear 16. The shaft rod 20 drives the deflection rod 14 to deflect. The deflection rod 14 pushes and pulls the push rod 13. The push rod 13 pushes the mounting bracket 8 and the cabinet door 5 out of the door groove 4. At the same time, when the mounting bracket 8 and the cabinet door 5 move, the plurality of sliding rods 11 slide horizontally and stably with the plurality of sliding grooves 10 to move the mounting bracket 8 and the cabinet door 5, releasing the sealing of the gap between the cabinet door 5 and the door groove 4 by the sealing strip 7. After the mounting bracket 8 and the cabinet door 5 are pushed out of the door groove 4, the maintenance personnel disassemble and replace the electrical components installed on the mounting bracket 8. Then the stepping motor 19 is powered on and rotated in the reverse direction, causing the deflection rod 14 to pull the push rod 13, the mounting bracket 8 and the cabinet door 5 to reset and insert into the door groove 4. The output end of the electric push rod 31 contracts to pull the pawl 30 to release the engagement with the ratchet wheel 29, realizing the maintenance and replacement of the electrical components in the cabinet body 2.
