Description
Technical Field
[0001] This utility model relates to the field of high and low voltage switchgear technology, specifically an outdoor rainproof high and low voltage switchgear. Background Technology
[0002] High and low voltage switchgear, also known as high and low voltage distribution cabinet, is a core device in the power system used for power distribution, control, metering and cable connection. In some cases, it is necessary to protect high and low voltage switchgear outdoors. However, in some rainy areas, high and low voltage switchgear may short-circuit if water gets into it. Therefore, rainproof high and low voltage switchgear is usually used when installing it outdoors. In the prior art, patent publication number CN 215378062 U discloses an outdoor rainproof high and low voltage switch, including a cabinet body and a cabinet door. The top of the cabinet body is open, and a rainproof component is provided on the top of the cabinet body. The rainproof component includes a cap-shaped top cover and an outer cover. The outer cover is fixedly installed outside the top cover. The top cover is fixedly installed on the top of the cabinet body. A plurality of second heat dissipation holes are provided on the side wall of the top cover. One end of each second heat dissipation hole is located on the inner wall of the top cover, and the other end extends downward at an angle to the outer wall of the top cover and is located above the plane where the bottom edge of the outer cover is located. The following are the shortcomings of this type of outdoor rainproof high and low voltage switchgear: the outer cover fixed on the upper surface of the switchgear can only protect the rainwater directly above it. When the wind and rain are heavy, the rainwater may fall on the sides of the switchgear and enter the interior of the switchgear through the gaps between the door and the body or the air inlet and outlet. It is difficult to achieve comprehensive rain protection for the switchgear and the protection capability is poor. Therefore, we propose an outdoor rainproof high and low voltage switchgear. Utility Model Content

Through a rainproof mechanism, a rain shield is used to cover the upper side of the high and low voltage switchgear, a deflector is used to guide rainwater falling on the protective door, a waterproof plate is used to prevent rainwater from splashing into the air outlet, and a rubber pad is added at the connection between the protective door and the cabinet body to achieve multi-directional rainproof protection for the cabinet body. This effectively isolates the inside of the cabinet body from external rainwater, providing strong rain protection capabilities and effectively solving the problems in the background technology.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an outdoor rainproof high and low voltage switch, including a cabinet body, wherein uniformly distributed mounting seats are fixedly connected to the rear surface of the cabinet body, and symmetrically distributed protective doors are hinged to the front surface of the cabinet body, and a rainproof mechanism is also included.

[0009] Furthermore, the lower surface of the cabinet is fixedly connected with evenly distributed support columns, and the lower ends of two adjacent support columns on the same side are fixedly connected with an installation plate to support the cabinet, making the cabinet higher than the ground and preventing water from entering the high and low voltage cabinet due to water accumulation on the ground.
[0010] Furthermore, the front surface of each protective door is fixedly connected with a glass window to facilitate observation of the internal condition of the high and low voltage switchgear.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This outdoor rainproof high and low voltage switchgear has the following advantages: The rainproof mechanism uses a rain shield to cover the upper side of the high and low voltage switchgear, a deflector to divert rainwater falling on the protective door, a waterproof board to prevent rainwater from splashing into the air outlet, and a rubber pad to add to the connection between the protective door and the cabinet, thus achieving multi-directional rainproof protection for the cabinet and effectively isolating the inside of the cabinet from external rainwater, providing strong rain protection capabilities.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3 This embodiment provides a technical solution: an outdoor rainproof high and low voltage switchgear, including a cabinet 1. The rear surface of the cabinet 1 is fixedly connected with uniformly distributed mounting seats 11. When using the outdoor rainproof high and low voltage switchgear, the protective door is opened and the high and low voltage switches are fixed to the mounting seats 11 by bolts and nuts. The front surface of the cabinet 1 is hinged with symmetrically distributed protective doors. The front surface of each protective door is fixedly connected with a glass window 4. A microcontroller 2 is fixedly connected to the front surface of the protective door. The input terminal of the microcontroller 2 is electrically connected to an external power supply. The lower surface of the cabinet 1 is fixedly connected with uniformly distributed support columns 6. The lower ends of two adjacent support columns 6 on the same side are fixedly connected with a mounting plate 7. The cabinet 1 also includes a rainproof mechanism 3. Rainproof mechanism 3 includes a rain shield 31, a deflector 32, a waterproof membrane 33, and a rubber pad 34. The rain shield 31 is fixedly connected to the upper surface of the cabinet 1. Deflectors 32 are fixedly connected to the lower front surface of the protective door and the lower front surface of the cabinet 1. A rubber pad 34 is fixedly connected to the front surface of the cabinet 1. The waterproof membrane 33 is fixedly connected to both the left and right surfaces of the cabinet 1. The waterproof membrane 33 has evenly distributed through holes inside. When it rains, rainwater falls onto the rain shield 31, preventing the upper surface of the cabinet 1 from getting wet. When it rains and the wind is strong, rainwater may be blown to... On the side of cabinet 1, the through-holes inside the waterproof plate 33 are downward-sloping ventilation holes. Even if rainwater splashes into the through-holes, it is difficult for it to enter the interior of cabinet 1. When rainwater falls onto the protective door and the front surface of cabinet 1, the rainwater slides down the protective door and the front surface of cabinet 1 onto the deflector plate 32. Then, the rainwater falls down the side of the deflector plate 32 away from the middle of cabinet 1, preventing rainwater from entering the interior of cabinet 1 through the gap between the protective door and cabinet 1. The rubber pad 34 serves as a second layer of protection to prevent rainwater from splashing into the interior of cabinet 1. The upper surface of the rain shield 31 is rotatably connected with symmetrically distributed rotating... The upper surface of the cabinet 1 is rotatably connected to symmetrically distributed electric push rods 9. The upper side of the telescopic end of each electric push rod 9 is rotatably connected to the lower surface of the adjacent rotating plate 5 on the same side. The input end of each electric push rod 9 is electrically connected to the output end of the microcontroller 2. When it is not raining, operating the microcontroller 2 activates the electric push rod 9, causing the telescopic end of the electric push rod 9 to extend and push the rotating plate 5 to rotate, facilitating smoother entry of external air into the cabinet 1. The upper surface of the cabinet 1 has an air inlet 8, and the left and right surfaces of the cabinet 1 each have an air outlet 12, which are connected to through holes on the same side. An intake fan 13 is fixedly connected to the upper inside of the cabinet 1, and an exhaust fan 10 is fixedly connected to both the left and right sides inside the cabinet 1. The input terminals of the intake fan 13 and the exhaust fan 10 are electrically connected to the output terminals of the microcontroller 2. When the microcontroller 2 is operated, the exhaust fan 10 and the intake fan 13 are started. The intake fan 13 starts and guides the outside air into the inside of the cabinet 1 along the air inlet 8 to blow air and dissipate heat inside the cabinet 1, and blows the hot air to the lower inside of the cabinet 1. The exhaust fan 10 runs and exhausts the hot air blown to the lower inside of the cabinet 1 through the air outlet 12.
[0016] The working principle of the outdoor rainproof high and low voltage switch provided by this utility model is as follows: When using this outdoor rainproof high and low voltage switch, open the protective door, fix the high and low voltage switches to the mounting base 11 with bolts and nuts, operate the microcontroller 2, and start the exhaust fan 10 and the intake fan 13. The intake fan 13 starts, guiding external air into the interior of the cabinet 1 along the air inlet 8 to blow air and dissipate heat from the interior of the cabinet 1, and blowing the hot air to the lower part of the interior of the cabinet 1. The exhaust fan 10 runs, and exhausts the hot air blown to the lower part of the interior of the cabinet 1 through the air outlet 12. When it rains, the rainwater falls onto the rain shield 31, so that the upper part of the cabinet 1 will not be covered with rainwater. When the rain is heavy and the wind is strong, the rainwater may be blown away. Water is blown to the side of cabinet 1. The through holes inside the waterproof plate 33 are downward-sloping ventilation holes. Even if rainwater splashes into the through holes, it is difficult for it to enter the interior of cabinet 1. When rainwater falls on the protective door and the front surface of cabinet 1, the rainwater slides down the protective door and the front surface of cabinet 1 onto the guide plate 32. Then the rainwater falls down the side of the guide plate 32 away from the middle of cabinet 1, preventing rainwater from entering the interior of cabinet 1 through the gap between the protective door and cabinet 1. The rubber pad 34 serves as a second layer of protection to prevent rainwater from splashing into the interior of cabinet 1. When it is not raining, the microcontroller 2 is operated to start the electric push rod 9, which extends the telescopic end of the electric push rod 9 and pushes the rotating plate 5 to rotate, making it easier for external air to enter the interior of cabinet 1.
[0017] It is worth noting that in the above embodiments, the microcontroller 2 is selected as AT89C51, the electric push rod 9 is selected as S909, and the exhaust fan 10 and the intake fan 13 are both selected as DF1751B48V-CFNN. The microcontroller 2 controls the operation of the electric push rod 9, the exhaust fan 10 and the intake fan 13 using methods commonly used in the prior art.
[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
