Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a waterproof distribution box. Background Art

[0002] The distribution box is a device used to distribute power supply. It is equipped with circuit breakers, fuses, circuit breakers, grounding devices and overvoltage protection devices. The structure of the waterproof distribution box mainly includes a waterproof sealed shell and an internal sealing design. The shell is made of waterproof plastic or metal materials, which has good waterproof performance and corrosion resistance, and the interior is equipped with a waterproof sealing ring and a waterproof wiring device to ensure that moisture cannot enter the interior. Its working principle is to prevent external moisture from entering the box through the sealing design and the selection of waterproof materials. The sealed shell can effectively prevent moisture from penetrating into the internal space through the surface, while the internal electrical Components and connectors also adopt a waterproof and sealed design, such as waterproof terminal blocks, waterproof switches, etc. However, in order to further achieve the purpose of rain protection, the current waterproof distribution box will arrange rain covers, rain shields and other structures on the top of itself. In this way, a fixed sealing plane is formed on the top of the waterproof distribution box. When there is no need to block or shelter from rain, the top of the box is difficult to open, which affects the ventilation effect inside the distribution box and makes it difficult for the heat inside the box to dissipate quickly. Especially in a high temperature environment or when the workload of the electrical equipment is large, the temperature inside the box will continue to rise, which can easily cause the electrical equipment to overheat or affect its life.

[0024] A rain cover 4 is arranged at the top of the upper sealed box 2. A pin shaft 3 is fixed on both inner walls of the rain cover 4. One end of the pin shaft 3 is rotatably connected to an outer wall of one side of the upper sealed box 2. A block 7 for blocking the heat dissipation port 501 is fixed on the top of the rain cover 4.

[0025] Swing arms 8, two swing arms 8 are provided, and the two swing arms 8 are symmetrically rotatably mounted on the inner wall of one side of the round-shaped inner liner 5, and are used to push the block 7 upward. A driving unit for driving the swing arms 8 to rotate is installed on the back of the round-shaped inner liner 5, and the driving unit is composed of a screw lifting module 10 and a gear tooth plate bidirectional transmission structure 11;

[0026] The screw lifting module 10 drives the two swing arms 8 to move synchronously through the gear plate bidirectional transmission structure 11, that is, the swing arm 8 lifts the block 7 upward, so that the block 7 and the rain cover 4 rotate around the pin shaft 3 until the block 7 is withdrawn to the outside of the heat dissipation port 501, and the heat dissipation port 501 leaks out;

[0027] A cavity 502 is provided between the outer wall of the round-shaped inner container 5 and the inner wall of the upper sealing box 2;

[0028] Back feet 201 are welded at the corners of the back of the upper sealed box 2. A notch is provided on one side of the outer wall of the back foot 201. The back foot 201 allows the back of the upper sealed box 2 to be bolted and fixed to a supporting carrier such as a wall.

[0029] The rain cover 4 is made of plastic material, and a slope 401 is provided on the top of the rain cover 4. A rectangular cut-out portion having the same length as the upper sealing box 2 is provided on the back of the rain cover 4. The slope 401 allows rainwater to flow out directly, thereby avoiding the situation where rainwater accumulates on the cover top.

[0030] The swing arm 8 includes a rotating shaft 801 rotatably mounted on the inner wall of one side of the circular inner liner 5, and a swing rod 802 fixed at one end of the rotating shaft 801. The gear tooth plate bidirectional transmission structure 11 is composed of a bidirectional tooth plate slidably mounted on the back of the circular inner liner 5, and a toothed disc fixed at the other end of the rotating shaft 801. The bidirectional tooth plate and the toothed disc are meshed with each other.

[0031] The screw lifting module 10 includes a U-shaped back plate 9 installed on the back of the circular inner tank 5, and a one-way screw rotatably installed on the surface of the U-shaped back plate 9, a nut sleeve is installed at the threaded part of one end of the one-way screw surface, a flat plate is installed on the surface of the nut sleeve, the top of the flat plate is fixedly connected to the bottom end of the two-way tooth plate, and a servo motor for driving the one-way screw to rotate is installed on one side of the surface of the U-shaped back plate 9. When the block 7 is lifted, the screw lifting module 10 drives the two-way tooth plate to move up, and the two-way tooth plate drives the two toothed discs to rotate synchronously, and the two-way tooth plate drives the rotating shaft 801 and the rocker arm 802 to rotate until the rocker arm 802 pushes the block 7 out to the outside of the heat dissipation port 501, so as to keep the internal ventilation unobstructed.

[0032] When the embodiment of the present application is in use, first, the circular inner liner 5 provides installation space for various electrical components 503, and a cavity 502 is formed between the circular inner liner 5 and the distribution box monomer 1, and a group of waterproof rings 6 are welded between the port of the circular inner liner 5 and the inner wall of the distribution box monomer 1, so that the circular inner liner 5 is arranged in the upper sealing box 2 in a similar suspended form. Even if water seepage or sealing failure occurs at the profile connection of the upper sealing box 2, the electrical components 503 inside the circular inner liner 5 will not touch water, thereby further improving the sealing performance of the upper sealing box 2. When the rain cover 4 is not needed, the staff turns on the screw lifting module 10 to work, and the screw lifting module 10 transmits the two-way transmission of the gear plate. The dynamic structure 11 drives the two swing arms 8 to move synchronously, that is, the swing arm 8 lifts the block 7 upward, so that the block 7 and the rain cover 4 rotate with the pin shaft 3 as the center, until the block 7 withdraws to the outside of the heat dissipation port 501. At this time, the heat dissipation port 501 leaks out, which is convenient for air circulation and beneficial to ventilation and heat dissipation. The rain cover 4 on the distribution box is installed on the top of the box in a hinged form. When there is no need to shelter from rain, the rain cover 4 can be actively lifted and opened to release the heat inside the box, thereby maintaining internal ventilation and avoiding heat accumulation and overheating of equipment. When the external environment cannot meet the ventilation needs, the rain cover 4 and the block 7 actively fall down under the action of gravity, ensuring the waterproof performance of the distribution box and effectively preventing rainwater from invading the interior of the box.
