[0019] A method for using a distribution box with automatic heat dissipation is applied to the distribution box with automatic heat dissipation as described above, and specifically comprises the following steps:

[0020] S1. Normal use: The main body of the distribution box is fixed on the ground through multiple support bases, and the filter holes and air circulation are used to achieve automatic heat dissipation and dust removal functions;

[0021] S2. Open the door panel: When the door panel needs to be opened, first press the rectangular sleeve to disengage the L-shaped hook from the ring block, release the braking state of the door panel, and then open the door panel so that the door panel is located inside the gap between the rectangular sleeve and the main body of the distribution box. Loosen the rectangular sleeve to move it up to the highest point, and then fully open the door panel. At this time, the dust inside the trapezoidal box can be discharged through the dust discharge hole and the inclined slot;

[0022] S3. Replace electrical components:

[0023] S31, releasing the fixing of the mounting plate: pressing the corresponding pressing plate, driving the sliding block to move upward, squeezing the second spring and entering the rectangular groove, the pressing plate enters the strip groove, driving the two triangular blocks to extend into the cavity, pushing the connecting plate and squeezing the third spring, the connecting plate drives the two clamping rods to retract and move out of the first clamping groove, releasing the braking state of the mounting plate;

[0024] S32, remove the installation plate: remove the installation plate from the strip-shaped slide groove, release the pressing plate, and make the clamping rod located inside insert into the first clamping groove located outside, and remove the installation plate and the wire receiving box to the outside of the distribution box body, leaving space for the replacement of electrical components;

[0025] S33, installing electrical components: inserting the mounting plate into the strip slides of different heights according to the requirements to facilitate the installation of electrical components;

[0026] S4. Pull out the wire storage box: When the wire storage box is pulled out, since a part of the wires of the electrical components is reserved and wound around the outside of the three wire winding rods, after the wire storage box is pulled out, the two upper wire winding rods move downward, and the one lower wire winding rod moves upward, changing the reserved wire from an S shape to a straight line shape, preventing the wire from breaking when the electrical components are pulled out.

[0027] In this application, during normal use, the main body of the distribution box is fixedly installed on the ground through multiple support seats. At this time, the external cold air exchanges with the hot air inside the main body of the distribution box through multiple filter holes, and the air enters along the gap between the rectangular sleeve box and the main body of the distribution box, making it difficult for heavier dust to enter the inside of the main body of the distribution box. The air that enters is filtered again by the filter holes, and at this time, the automatic heat dissipation function of the electrical components inside the main body of the distribution box can be realized;

[0028] And when the external air circulates, the air will continuously push the rectangular sleeve box and the triangular inclined plate downward. The rectangular sleeve box drives the support block downward, the support block drives the trapezoidal box downward, and the trapezoidal box squeezes the compression spring. When the wind force decreases, the elastic force of the compression spring helps the trapezoidal box to reset, and the continuous vibration of the trapezoidal box and the support block is realized. At this time, it can help the vibration of the dust inside the trapezoidal box, and then it can slide down along the inclined surface of the trapezoidal box to the side close to the dust discharge hole, which is convenient for subsequent discharge and will not block the filter holes, ensuring the normal circulation of air;

[0029] When it is necessary to replace the electrical components inside the main body of the distribution box, since the annular block is engaged with the L-shaped hook at this time, it can not only prevent the support block from rising excessively but also prevent the door panel from being opened. At this time, it is necessary to first press the rectangular sleeve box. The rectangular sleeve box drives the L-shaped hook downward through the support block and the trapezoidal box. After the L-shaped hook disengages from the annular block, the braking state of the door panel can be released;

[0030] At this time, the door panel can be opened, making the annular block disengage from the L-shaped hook, but the door panel can only be opened a little. At this time, the door panel can be located inside the gap between the rectangular sleeve box and the main body of the distribution box. Release the rectangular sleeve box, making the rectangular sleeve box move upward. When the rectangular sleeve box moves to the highest point, then open the door panel completely. The top of the door panel supports the rectangular sleeve box to prevent the rectangular sleeve box from moving downward. At the same time, when the rectangular sleeve box moves to the highest point, the dust inside the trapezoidal box is discharged through the dust discharge hole and the inclined groove, which is convenient for subsequent air filtration;

[0031] At this time, the interior of the distribution box main body is completely exposed, and the electrical components that need to be replaced can be replaced. Moreover, the corresponding pressing plate can be pressed. The pressing plate drives the sliding block to move upward. The sliding block squeezes the second spring and enters the interior of the rectangular groove. The pressing plate enters the interior of the strip-shaped groove. The pressing plate drives the two triangular blocks to extend into the interior of the cavity. At this time, the triangular blocks push the connecting plate and squeeze the third spring. The connecting plate drives the two clamping rods to retract, and the clamping rods are removed from the interior of the first clamping groove, and the braking state of the mounting plate can be released. After the mounting plate is removed from the interior of the strip-shaped sliding groove, the pressing plate is released, so that the clamping rod located inside is clamped into the interior of the first clamping groove located outside, so that the mounting plate and the wire collecting box are removed to the outside of the distribution box main body, leaving space for the convenience of replacing electrical components. Moreover, the heights of the three strip-shaped sliding grooves are inconsistent, and the mounting plate can be inserted into the strip-shaped sliding grooves with different heights according to requirements, which is convenient for the installation of electrical components;

[0032] At the same time, when the wire collecting box is pulled out, at this time, since a part of the wires of the electrical components is reserved and wound around the outer parts of the three wire winding rods. At this time, after the wire collecting box is pulled out, the two wire winding rods located above move downward, and the one wire winding rod located below moves upward. Furthermore, the reserved conducting wires are changed from an S shape to a straight shape, avoiding the breakage of the conducting wires when the electrical components are pulled out, prolonging the service life of the device, and being convenient to use.

[0033] Beneficial effects: The air exchange between the inside and outside of the distribution box main body is realized through the filter holes, and the air enters along the gap between the rectangular sleeve box and the distribution box main body, making it difficult for heavier dust to enter the interior. At the same time, the external air flow is utilized to push the rectangular sleeve box and the triangular inclined plate to move downward, driving the trapezoidal box to vibrate, helping the internal dust to slide down, ensuring the normal air circulation, and realizing the automatic heat dissipation function.

[0034] The design of the trapezoidal box and its cooperation with the L-shaped fixing block facilitate the dust to slide down along the inclined plane to one side of the dust discharge hole and will not block the filter holes, ensuring the normal air circulation.

[0035] By using the engagement of the annular block and the L-shaped hook, the excessive rising of the support block and the random opening of the door panel can be avoided; by pressing the rectangular sleeve box to disengage the L-shaped hook from the annular block, the braking of the door panel can be released, and the door panel can be located inside the gap between the rectangular sleeve box and the distribution box main body, facilitating subsequent operations.

[0036] The engagement of the clamping rod and the first clamping groove in the fixing component can fix the mounting plate and the distribution box main body; pressing the pressing plate can release the braking state of the mounting plate, facilitating the removal of the mounting plate from the strip-shaped sliding groove, and the heights of the strip-shaped sliding grooves are inconsistent, and it can be inserted into the strip-shaped sliding grooves with different heights according to requirements, which is convenient for the installation of electrical components.

[0037] The arrangement of the wire winding rods in the winding component makes the reserved conducting wires change from an S shape to a straight shape when the wire collecting box is pulled out, avoiding the breakage of the conducting wires when the electrical components are pulled out and prolonging the service life of the device.

The heat dissipation component includes a support block 13 slidably penetrating through the inside of the rectangular hole 18. Trapezoidal boxes 15 are fixedly connected to both sides of the support block 13. The top of the trapezoidal box 15 is inclined. A plurality of filter holes 14 are opened on the bottom inner wall of the trapezoidal box 15. A dust discharge hole 16 is opened on one inner wall of the trapezoidal box 15.

When it is necessary to replace the electrical components inside the distribution box main body 1, since the annular block 7 is engaged with the L-shaped hook 17 at this time, it can not only prevent the support block 13 from rising excessively, but also prevent the door panel 4 from being opened. At this time, it is necessary to first press the rectangular sleeve box 2. The rectangular sleeve box 2 drives the L-shaped hook 17 to move downward through the support block 13 and the trapezoidal box 15. After the L-shaped hook 17 is disengaged from the annular block 7, the braking state of the door panel 4 can be released. A handle 5 is fixedly connected to the other side of the door panel 4.

And when the external air circulates, at this time, the air will continuously push the rectangular sleeve box 2 and the triangular inclined plate 3 to move downward. The rectangular sleeve box 2 drives the support block 13 to move downward. The support block 13 drives the trapezoidal box 15 to move downward.
