Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and more particularly to an outdoor power distribution cabinet and a method for using the same. Background Art

[0002] An outdoor distribution cabinet is a complete set of power distribution equipment assembled from primary and secondary equipment according to a specific electrical circuit scheme. It is mainly used in outdoor environments and is responsible for distributing electrical energy to various electrical devices while also monitoring and controlling the power supply. In the event of abnormal conditions such as circuit overload, short circuit, or leakage, the outdoor distribution cabinet can quickly cut off the power supply to protect the safety of equipment and personnel.

[0003] The heat dissipation vents of outdoor distribution cabinets serve as channels for discharging hot air, and inevitably become portals for air exchange inside and outside the distribution cabinet. In areas with high humidity or during the rainy season, moisture can easily penetrate into the interior of the distribution cabinet through the heat dissipation vents, affecting the normal operation of the distribution cabinet. In addition, although the current heat dissipation vents have added moisture absorption functions, over time, the moisture-absorbing structure will gradually reach a half-full or even fully saturated state due to moisture accumulation. If not handled in time, the ventilation and heat dissipation and dehumidification functions of the heat dissipation vents will be affected, making it impossible to provide long-term and stable moisture protection for the interior of the distribution cabinet.

[0004] To this end, the present application proposes an outdoor power distribution cabinet and a method of using the same to solve the above problems. Summary of the Invention

[0005] Technical problem to be solved: In response to the problems existing in the prior art, the purpose of the present invention is to provide an outdoor distribution cabinet and a method of use thereof, which solves the problem that the heat dissipation port of the outdoor distribution cabinet is easily permeated with moisture in a high humidity environment. Although it has a moisture absorption function, it will be in a saturated state after long-term use, affecting the ventilation, heat dissipation and dehumidification functions.

[0006] Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] The utility model relates to an outdoor power distribution cabinet, comprising a cabinet body and a fitting opening provided on the side of the cabinet body, and further comprising: a heat dissipation plate, which is rotatably installed in the fitting opening; an adjustment component, which is provided on the inner side of the heat dissipation plate and is installed inside the cabinet body, and is used to adjust the inclination angle of the heat dissipation plate; heat dissipation holes, which are evenly arranged and distributed on the heat dissipation plate; a moisture separation ball, which is embedded in the heat dissipation hole and is divided into a moisture absorption part and a breathable part, and the end in contact with the external air is the moisture absorption part, and the moisture separation ball is made of elastic sponge material; three overflow strips are provided, one end of each of which is connected to the middle of the moisture absorption part, and the overflow strips are made of elastic stretch breathable material, and are used to tighten the moisture absorption part; an inner movable The vertical column ring is arranged at the rear part of the wet ball separation, and the front middle part is connected to the other end of the three overflow pull strips running through the breathable part; the connecting ball belt is equidistantly arranged and installed inside the inward-moving vertical column ring; the upper and lower hole walls of the heat dissipation hole are provided with sliding grooves, and a middle-loaded magnetic block slides in the sliding groove, and the rear part of the middle-loaded magnetic block is connected to the rear wall of the sliding groove through a spring, and the middle-loaded magnetic block is fixedly installed on the top and bottom of the inward-moving vertical column ring respectively; a ball-repelling assembly is provided at the front part of the sliding groove, and the ball-repelling assembly is aligned with the horizontal axis of the sliding groove as the center, and is triggered by the tilt of the heat dissipation plate, and the ball-repelling assembly rolls and flips over the magnetic repulsion to drive the middle-loaded magnetic block inward.

[0009] In a new embodiment, the adjustment component includes: two electric telescopic rods, which are vertically arranged on the left and right sides of the top of the fitting port, and installed on the upper part of the inner wall of the cabinet on the same side as the fitting port; a positioning block, which is installed on the telescopic end of the electric telescopic rod; two fixed pulleys, which are vertically arranged on the lower part of the electric telescopic rod, and also installed on the inner wall of the cabinet on the same side as the electric telescopic rod; an assembly block, which is installed on the left and right sides of the upper rear end of the heat dissipation plate; a hanging rope, one end of which is connected to the positioning block, and the other end is connected to the assembly block in the corresponding direction through the fixed pulley.

[0010] In a new embodiment, the ball-repelling assembly includes: a through groove, which is opened at the front of the sliding groove and is centered on the same horizontal axis as the sliding groove. The bottom wall of the through groove is an inclined surface, and the inclination angle of the inclined surface is 10 to 15 degrees. The inner wall of the through groove is a wear-resistant layer; a gravity magnetic ball, which rolls in the through groove, and the gravity magnetic ball is divided into a non-magnetic hemisphere and a same-magnetic hemisphere; a groove ring, which is installed at the rear of the through groove and is used to separate the sliding groove and the through groove.

[0011] In a new embodiment, a plurality of hollow heat storage balls are installed at equal intervals on each connecting wire of the connecting ball belt, and the hollow heat storage balls include a heat storage outer layer, convection holes and an elastic air-permeable slope. A convection hole is opened in the middle of the heat storage outer layer, and heat storage particles are filled between the heat storage outer layer and the convection hole. Elastic air-permeable slopes are installed on the upper and lower inner walls of the convection hole, and the elastic air-permeable slopes are filled with insecticide volatile particles.

[0012] In a new embodiment, the outer wall of the inward-moving vertical column ring slides in a sealed manner with the inner wall of the heat dissipation hole, and the inward-moving vertical column ring is made of a hard waterproof material.

[0013] In a new embodiment, a louver fan is installed on the front of the heat dissipation plate, and a sealing frame strip is installed on the plate frame edge of the heat dissipation plate.

[0014] In a new embodiment, a pressure detector is fixedly installed at the bottom end of the heat sink, and the pressure detector is wirelessly connected to a microcontroller. The microcontroller is installed in the middle of the inner wall of the cabinet on the same side as the fitting port, and the microcontroller is electrically connected to the electric telescopic rod.

[0015] A method for using an outdoor power distribution cabinet comprises the following steps:

[0016] S1. When the outdoor air is humid, the heat dissipation holes absorb moisture through the internal separated wet balls. When the separated wet balls reach the saturated state, the pressure detector detects the change in the weight of the heat sink. The microcontroller then controls the adjustment component to drive the heat sink to tilt, so that the heat sink is in the dehumidification state.

[0017] S2. Continuing with the above steps, the operation process of the adjustment component is to control the extension of the electric telescopic rod, thereby driving the positioning block connected to the telescopic end to move downward, so that the positioning block drives the taut rope to be continuously released. Since the heat sink rotates to the mounting port via the lower torsion spring, the heat sink is in a released state guided by the fixed pulley. When one end of the above rope is released, the other end of the rope is connected to the heat sink by the mounting block, which rotates the outside and tilts, thereby providing driving force for the ball repulsion assembly on the heat sink;

[0018] S3. The ball repulsion component is affected by the driving force, which drives the gravity magnetic ball in the slot to roll, causing the gravity magnetic ball to change direction. The magnetic hemisphere and the middle magnetic block in the sliding slot produce a magnetic repulsion effect, driving the inward vertical column ring connected to the middle magnetic block to move inward, and driving the tightening of the overflow pull bar to tighten the separation of the wet ball to squeeze out the moisture it has absorbed, so that it drips to the outside of the cabinet along the inclined direction of the heat sink;

[0019] S4. After separating the wet balls, the hollow heat storage balls distributed on the wire ball belt are used to form a thermal barrier and an internal drug flow. The thermal barrier prevents moisture from flowing back, and the internal drug flow evaporates with the heat dissipation to prevent external pests from clogging the heat sink.

[0020] Beneficial effects: Compared with the prior art, the advantages of the present invention are:

[0021] By setting up a separating wet ball and an overflow strip, the wet separation of the separating wet ball is utilized to promote the airflow inside and outside, keep the inside of the distribution cabinet dry, and use the overflow strip connected to the moisture absorbing part. After the moisture absorbing part absorbs moisture and expands to saturation, the moisture absorbing part is tightened by stretching the overflow strip, so that the moisture absorbing part is tightened and the moisture is squeezed out, and the moisture absorbing part is dried and dehumidified.

[0022] By utilizing the inward-moving vertical column ring and the connecting ball belt to form a thermal barrier, on the one hand, a portion of the exhaust heat is intercepted and absorbed by the connecting ball belt to form a heat-slow heat dissipation barrier net. The heat released by the absorption forms a flowing thermal barrier from top to bottom due to gravity, which blocks the moisture from escaping from the wet ball and the overflow strip.

[0023] By setting up a hollow heat storage ball, during the heat dissipation process, the hollow heat storage ball can not only store and dissipate heat, but also, under the influence of the heat dissipation airflow, the built-in elastic breathable slope blows the insecticide volatile particles in the internal elastic breathable slope through the convection holes to release volatile medicine smell, providing a solution to the insect pest problem in the external environment of the cabinet.

[0024] By setting an adjustment component, the connected positioning block is driven downward by the electric telescopic rod, so that the positioning block drives the taut suspension rope to be continuously released. Since the heat sink is rotated to the mounting port through the lower torsion spring, the heat sink is in a released state guided by the fixed pulley. When one end of the suspension rope is released, the other end of the suspension rope is connected to the heat sink by the assembly block and will rotate and tilt externally, which is convenient for the physical discharge of moisture squeezed out by the moisture absorbing part of the separation humidification ball, without the need for manual intervention, thereby improving the intelligence level of the distribution cabinet.

[0025] By setting up the ball repulsion component, it is first affected by the tilt of the heat sink, driving the gravity magnetic ball in the groove to roll, causing the gravity magnetic ball to change direction, so that its magnetic hemisphere part is aligned with the middle-loaded magnetic block in the sliding groove, thereby generating a magnetic repulsion effect, driving the inward vertical column ring connected to the middle-loaded magnetic block to move inward, and driving the tightening of the overflow strip to tighten the separation wet ball to squeeze out the moisture it has absorbed, so that it drips to the outside of the cabinet along the tilt direction of the heat sink.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] The embodiments of the present application provide an outdoor power distribution cabinet and a method for using the same, thereby solving the problem that the heat dissipation vents of an outdoor power distribution cabinet are easily permeated with moisture in a high-humidity environment. Although the heat dissipation vents have a moisture absorption function, they will be in a saturated state after long-term use, thereby affecting the ventilation, heat dissipation, and dehumidification functions. During use, when the moisture absorption structure of the heat dissipation vents of the power distribution cabinet reaches a saturated state due to moisture accumulation, it is possible to handle the problem in a timely manner, thereby affecting the ventilation, heat dissipation, and dehumidification functions of the heat dissipation vents.

[0042] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0043] Example 1

[0044] See also Figures 1-13 An outdoor power distribution cabinet includes a cabinet body 1 and a mounting port 2 provided on a side of the cabinet body 1, and further includes:

[0045] The heat dissipation plate 3 is rotatably mounted in the fitting opening 2;

[0046] The adjustment component 4 is provided on the inner side of the heat sink 3 and installed inside the cabinet 1, and is used to adjust the tilt angle of the heat sink 3;

[0047] Heat dissipation holes 5 are evenly spaced and arranged on the heat dissipation plate 3;

[0048] The humidifying ball 6 is embedded in the heat dissipation hole 5 and is divided into a hygroscopic portion 61 and a breathable portion 62. The end in contact with the outside air is the hygroscopic portion 61. The humidifying ball 6 is made of elastic sponge.

[0049] There are three overflow strips 7, one end of each of which is connected to the middle of the moisture absorption part 61. The overflow strips 7 are made of elastic, stretchable and breathable material and are used to tighten the moisture absorption part 61.

[0050] The inward-moving vertical column ring 8 is arranged at the rear of the separating wet ball 6, and the front middle part is connected to the other end of the three overflow braces 7 that pass through the air-permeable portion 62;

[0051] The connecting ball belts 9 are equidistantly arranged and installed inside the inward vertical column ring 8;

[0052] A sliding groove 10 is provided at the upper and lower hole walls of the heat dissipation hole 5, and a middle-loaded magnetic block 11 slides in the sliding groove 10. The rear part of the middle-loaded magnetic block 11 is connected to the rear wall of the sliding groove 10 through a spring 12, and the middle-loaded magnetic block 11 is fixedly mounted on the top and bottom of the inward-moving vertical column ring 8 respectively; a ball-repelling assembly 13 is provided at the front part of the sliding groove 10, and the ball-repelling assembly 13 is aligned with the transverse axis of the sliding groove 10 as the center. When triggered by the tilt of the heat dissipation plate 3, the ball-repelling assembly 13 rolls and flips over to drive the middle-loaded magnetic block 11 to move inward by magnetic repulsion.

[0053] In this example, see Figures 1-13As shown, by setting up a separating wet ball 6 and an overflow strip 7, the separating wet ball 6 is first used to separate the wetness, and the moisture absorbing part 61 absorbs moisture from the external moisture, and the internal breathable part 62 opens up the internal space, promotes the flow of air inside and outside, keeps the inside of the distribution cabinet dry, and prevents the failure or corrosion of the electrical equipment inside the cabinet 1 caused by excessive humidity, and uses the overflow strip 7 connected to the moisture absorbing part 61. After the moisture absorbing part 61 absorbs moisture and expands to saturation, the moisture absorbing part 61 is tightened by stretching the overflow strip 7, so that the moisture absorbing part 61 of the separating wet ball 6 is tightened to squeeze out the moisture, and the moisture absorbing part 61 is dried and dehumidified.

[0054] By setting up an inward-moving vertical column ring 8, a connecting ball belt 9, a sliding groove 10, a middle-loaded magnetic block 11 and a spring 12, and utilizing the thermal barrier composed of the inward-moving vertical column ring 8 and the connecting ball belt 9, on the one hand, a portion of the heat dissipation is intercepted, so that the heat-slow heat dissipation barrier net formed by the connecting ball belt 9 absorbs and releases heat to form a flowing thermal barrier from top to bottom due to gravity, thereby blocking the moisture escape from the wet ball 6 and the overflow strip 7. Secondly, by utilizing the sliding groove 10, the middle-loaded magnetic block 11 and the spring 12, a moving driving structure is provided for the inward-moving vertical column ring 8, and a moving pulling structure is provided for the overflow strip 7 connected to the inward-moving vertical column ring 8, thereby realizing that the subsequent ball-repelling component 13 drives the inward-moving vertical column ring 8 to move and pull the overflow strip 7.

[0055] Further, see Figure 10 、 Figure 12 and Figure 13 A plurality of hollow heat storage balls 14 are evenly spaced on each connecting wire of the connecting ball belt 9. The hollow heat storage ball 14 includes a heat storage outer layer 141, convection holes 142 and an elastic air-permeable slope 143. A convection hole 142 is provided in the middle of the heat storage outer layer 141. Heat storage particles are filled between the heat storage outer layer 141 and the convection holes 142. Elastic air-permeable slopes 143 are installed on the upper and lower inner walls of the convection holes 142, and insecticide volatile particles are filled in the elastic air-permeable slopes 143.

[0056] By setting the connected ball belt 9, the hollow heat storage ball 14, the heat storage outer layer 141, the convection holes 142 and the elastic breathable slope 143, a thermal barrier is constructed by the connected ball belt 9 and the hollow heat storage ball 14. The hollow heat storage ball 14 is composed of the heat storage outer layer 141, the convection holes 142 and the elastic breathable slope 143. During the heat dissipation process, the hollow heat storage ball 14 can not only store and dissipate heat, but also dissipate heat through its built-in elastic breathable slope 143 under the influence of the heat dissipation airflow. The airflow blows the insecticide volatile particles in the internal elastic breathable slope 143 through the convection holes 142 to release volatile medicinal smell, providing a solution to the insect pest problem in the external environment of the cabinet 1, enhancing the practicality of the thermal barrier and moisture insulation, and giving it an eco-friendly pest control ability.

[0057] Further, see Figure 6 and Figure 7 The outer wall of the inward-moving vertical column ring 8 slides in a sealed manner with the inner wall of the heat dissipation hole 5. The inward-moving vertical column ring 8 is made of a hard waterproof material. This hard waterproof material has high strength and rigidity, and can maintain a stable shape during movement, and is not easily deformed or damaged. This stability not only ensures smooth sealing and sliding, but also ensures the normal operation of the overflow brace 7 tensioning and the ball repelling assembly 13 driving.

[0058] Further, see Figure 3-Figure 5 A louver fan 15 is installed in front of the heat dissipation plate 3, and a sealing frame strip 16 is installed on the plate frame edge of the heat dissipation plate 3. By arranging the louver fan 15 and the sealing frame strip 16, the sealing frame strip 16 is tightly installed at the junction of the heat dissipation plate 3 and the cabinet body 1, ensuring that the two are sealed and closed, preventing the infiltration of moisture, effectively resisting the intrusion of adverse external factors such as rain and dust, and maintaining the dryness of the environment inside the cabinet. At the same time, the louver fan 15 placed in front of the heat dissipation plate 3 improves the air circulation efficiency and expands the heat dissipation area, so that the heat generated inside the distribution cabinet can be quickly discharged to the outside of the cabinet through the synergistic effect of the heat dissipation holes 5 on the heat dissipation plate and the louver fan 15, thereby reducing the temperature inside the cabinet and ensuring the continuous and stable operation of the equipment.

[0059] Example 2

[0060] See also Figure 2 and Figure 3 , the regulating component 4 includes:

[0061] Two electric telescopic rods 41 are provided, which are vertically arranged on the left and right sides of the top of the fitting opening 2 and installed on the upper part of the inner wall of the cabinet 1 on the same side as the fitting opening 2;

[0062] A positioning block 42 is mounted on the telescopic end of the electric telescopic rod 41;

[0063] There are two fixed pulleys 43, which are vertically arranged at the lower part of the electric telescopic rod 41 and are also installed on the inner wall of the cabinet 1 on the same side as the electric telescopic rod 41;

[0064] Assembly blocks 44, which are mounted on the left and right sides of the upper rear end of the heat sink 3;

[0065] One end of the suspension rope 45 is connected to the positioning block 42 , and the other end is connected to the assembly block 44 in the corresponding direction through the fixed pulley 43 .

[0066] In this example, see Figure 2 and Figure 3As shown, by setting the electric telescopic rod 41, positioning block 42, fixed pulley 43, assembly block 44 and hanging rope 45, the electric telescopic rod 41 is first started to extend, so that the positioning block 42 connected to its telescopic end moves downward, so that the positioning block 42 drives the taut hanging rope 45 to be continuously released. Since the heat sink 3 is rotated to the fitting port 2 through the lower torsion spring, the heat sink 3 is in a released state guided by the fixed pulley 43. When one end of the above-mentioned hanging rope 45 is released, the other end of the hanging rope 45 is connected to the heat sink 3 by the assembly block 44, which will rotate and tilt externally, driving the internal ball repulsion component 13 to move the middle magnetic block 11 inward through the rolling and flipping magnetic repulsion, tightening the overflow strip 7 to complete the discharge of moisture from the moisture absorption part 61 separating the wet ball 6, without manual intervention, thereby improving the intelligence level of the distribution cabinet (in addition, due to the limitation of external humidity, the adjustment component 4 acting on dehumidification will also be affected by the external temperature and humidity. When the external temperature and humidity are large, it will not be turned on, but will perform dehumidification operation after the temperature and humidity detection is qualified).

[0067] Further, see Figure 3 and Figure 5 A pressure detector 17 is fixedly installed at the bottom end of the heat sink 3. The pressure detector 17 is wirelessly connected to the microcontroller 18. The microcontroller 18 is installed in the middle of the inner wall of the cabinet 1 on the same side as the fitting port 2. The microcontroller 18 is electrically connected to the electric telescopic rod 41.

[0068] By setting up a pressure detector 17 and a microcontroller 18, the pressure detector 17 is used to detect the weight change of the heat sink 3. When the gravity exceeds the set weight value, the pressure detector 17 transmits a signal to the microcontroller 18, so that the microcontroller 18 controls the start of the electric telescopic rod 41, and further controls the start and stop of the adjustment component 4.

[0069] Example 3

[0070] See also Figure 6 、 Figure 7 and Figure 11 , the ball-repelling component 13 includes:

[0071] The through groove 131 is formed in front of the sliding groove 10 and is centered on the same transverse axis as the sliding groove 10. The bottom wall of the through groove 131 is an inclined surface with an inclination angle of 10 to 15 degrees. The inner wall of the through groove 131 is a wear-resistant layer.

[0072] The gravity magnetic ball 132 rolls in the through groove 131 and is divided into a non-magnetic hemisphere portion and a magnetic hemisphere portion;

[0073] The groove ring 133 is installed at the rear of the through groove 131 to separate the sliding groove 10 from the through groove 131 .

[0074] In this example, see Figure 6 、 Figure 7 and Figure 11 As shown, by setting the through groove 131, the gravity magnetic ball 132 and the groove ring 133, the ball repulsion component 13 is affected by the tilting effect of the heat sink 3, which will drive the gravity magnetic ball 132 in the through groove 131 to roll, so that the gravity magnetic ball 132 changes its direction, and its magnetic hemisphere part is aligned with the middle magnetic block 11 in the sliding groove 10, thereby generating a magnetic repulsion effect, driving the inward vertical column ring 8 connected to the middle magnetic block 11 to move inward, and driving the tightening of the overflow pull strip 7 to tighten the separation wet ball 6 to squeeze out the moisture it has absorbed, so that it drips to the outside of the cabinet 1 along the tilting direction of the heat sink 3.

[0075] Example 4

[0076] See also Figures 1-13 A method for using an outdoor power distribution cabinet, which is adapted to the outdoor power distribution cabinet described in Example 1, includes the following steps:

[0077] S1. When the outdoor air is humid, the heat dissipation holes 5 absorb moisture through the internal moisture-absorbing spheres 6. When the moisture-absorbing spheres 6 reach saturation, the pressure detector 17 detects a change in the weight of the heat dissipation plate 3. The microcontroller 18 controls the adjustment component 4 to tilt the heat dissipation plate 3, so that the heat dissipation plate 3 is in a moisture-dissipating state.

[0078] S2. Continuing with the above steps, the operation process of the adjustment assembly 4 is to control the extension of the electric telescopic rod 41, thereby driving the positioning block 42 connected to the telescopic end to move downward, so that the positioning block 42 drives the taut suspension rope 45 to be continuously released. Since the heat sink 3 is rotated to the fitting port 2 via the lower torsion spring, the heat sink 3 is in a released state guided by the fixed pulley 43. When one end of the suspension rope 45 is released, the other end of the suspension rope 45 is connected to the heat sink 3 by the assembly block 44, and the heat sink 3 rotates externally and tilts, thereby providing driving force for the ball-repelling assembly 13 on the heat sink 3.

[0079] S3. The ball repelling assembly 13 is affected by the driving force, which drives the gravity magnetic ball 132 in the slot 131 to roll, causing the gravity magnetic ball 132 to change direction. The magnetic repulsion effect is generated by the magnetic hemisphere and the middle magnetic block 11 in the sliding slot 10, driving the inward vertical column ring 8 connected to the middle magnetic block 11 to move inward, and driving the tightening of the overflow pull bar 7, thereby tightening the separation wet ball 6 to squeeze out the moisture it has absorbed, so that it drips to the outside of the cabinet 1 along the inclined direction of the heat sink 3;

[0080] S4. After the moisture is separated by the separated humidifying balls 6, the hollow heat storage balls 14 distributed on the connecting ball belt 9 are used to form a heat barrier and an internal permeable drug flow. The heat barrier prevents moisture from flowing back, and the internal permeable drug flow evaporates with the heat dissipation to prevent external pests from clogging the heat dissipation plate 3.

[0081] In summary, the beneficial effects of this method are as follows:

[0082] Through the built-in separated moisture ball 6 and pressure detector 17, real-time monitoring of the moisture status in the heat dissipation area can be achieved. Once the moisture reaches the preset saturation level, the dehumidification mechanism is triggered without human intervention, thereby improving the operating safety of the distribution cabinet and preventing electrical failures caused by moisture accumulation.

[0083] In order to further optimize the dehumidification effect, the microcontroller 18 and the regulating component 4 are used to control the tilt angle of the heat sink 3 according to the dehumidification demand, changing it from a horizontal state to an inclined state, and using physical principles to accelerate the squeezing of wet water discharge to maximize the dehumidification efficiency.

[0084] The ball repulsion component 13 uses the magnetic repulsion between the gravity magnetic ball 132 and the middle load magnetic block 11 to provide driving force for the inward moving vertical column ring 8, thereby pulling the overflow pull bar 7 to compress and separate the wet ball 6 to discharge moisture. This compact and efficient magnetic repulsion drive mechanism ensures the timeliness and thoroughness of moisture discharge.

[0085] The hollow heat storage balls 14 embedded in the wire ball belt 9 form a thermal barrier to block moisture leakage, and the insect-repellent volatile particles filled in the elastic breathable slope 143 emit a medicinal smell with an insect repellent effect, effectively preventing external pests from invading and clogging the heat sink 3, which not only enhances the protection performance of the distribution cabinet, but also significantly extends its overall service life.

[0086] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.

8. A method for using an outdoor power distribution cabinet, comprising the outdoor power distribution cabinet according to any one of claims 3 to 7, characterized in that: The following steps are involved: S1. When the outdoor air is in a humid state, the heat dissipation hole (5) absorbs moisture through the internal separation wet ball (6). When the separation wet ball (6) reaches a saturated moisture absorption state, the pressure detector (17) detects that the weight of the heat dissipation plate (3) has changed, and the microcontroller (18) controls the adjustment component (4) to drive the heat dissipation plate (3) to tilt, so that the heat dissipation plate (3) is in a moisture-dissipating state; S2, continuing the above steps, the operation process of the adjustment component (4) is to control the extension of the electric telescopic rod (41), thereby driving the positioning block (42) connected to the telescopic end to move downward, so that the positioning block (42) drives the tightened rope (45) to be continuously released. Since the heat sink (3) is rotated to the fitting port (2) through the lower torsion spring, the heat sink (3) is in a released state guided by the fixed pulley (43). When one end of the rope (45) is released, the other end of the rope (45) is connected to the heat sink (3) by the assembly block (44) and rotates to the outside to tilt, thereby providing driving force for the ball repulsion component (13) on the heat sink (3); S3, the ball repulsion component (13) is affected by the driving force, which drives the gravity magnetic ball (132) in the through slot (131) to roll, causing the gravity magnetic ball (132) to change direction, and the magnetic hemisphere portion and the middle magnetic block (11) in the sliding slot (10) produce a magnetic repulsion effect, driving the inward moving vertical column ring (8) connected to the middle magnetic block (11) to move inward, and driving the tightening of the overflow pull bar (7) to tighten the separation wet ball (6) to squeeze out the moisture it has absorbed, so that it drips to the outside of the cabinet (1) along the inclined direction of the heat dissipation plate (3); S4, after the moisture is separated by the separated wet balls (6), the hollow heat storage balls (14) distributed on the connecting ball belt (9) are used to form a heat barrier and an internal permeable drug flow. The heat barrier prevents moisture from flowing back, and the internal permeable drug flow evaporates the drug smell with the heat dissipation to prevent external pests from clogging the heat dissipation plate (3).
