[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a power distribution cabinet, which has the following beneficial effects: The distribution cabinet is used by the cabinet body, cabinet door, dehumidification assembly and dehumidification ball. The electrical components in the distribution cabinet are installed on the galvanized plate. There are several dehumidification balls rolling on the baffle of the dehumidification disk. These dehumidification balls can absorb the water vapor sinking in the distribution cabinet. When the dehumidification balls reach saturation, they will gradually be arranged at the goal hole, waiting for the top ball assembly to send the saturated dehumidification balls into the drying circulation pipe for drying. The saturated dehumidification balls enter the receiving seat through the goal hole. At this time, the top ball part 1 slides downward and separates from the top ball part 2 under the drive of the motor and the swing rod. As the motor continues to rotate, the top ball part 1 with the dehumidification ball gradually rises and approaches the top ball part 2. The dehumidification ball located on the receiving seat pushes the blocking part to both sides, and the check rod retracts into the sleeve. The dehumidification ball enters the connecting pipe. Once the dehumidification ball passes through the blocking part, the low blocking part will be reset under the action of the spring to prevent the dehumidification ball entering the connecting pipe from falling back. Since the drying circulation pipe is tightly filled with dehumidification balls, when a saturated dehumidification ball is pushed in from one side of the drying circulation pipe, a dried dehumidification ball will be spit out from the other side of the drying circulation pipe. Under the action of the motor and the swing rod, when the top ball piece 1 slides downward, the swing rod connected to the connecting rod 1 pulls the connecting rod 1, thereby pulling the connecting rod 2, the connecting rod 3, and the connecting rod 4, and the connecting rod 4 pulls the slider, so that the storage hole on the slider and the through hole on the sliding frame coincide with each other, and the dehumidification ball in one end of the drying circulation pipe connected with the through hole enters the storage hole through the through hole. When the top ball piece 1 rises and pushes a dehumidification ball into the drying circulation pipe, under the action of the motor and the swing rod, the swing rod pushes the connecting rod 1, thereby pushing the connecting rod 2, the connecting rod 3, and the connecting rod 4, and the connecting rod 4 pushes the slider, so that the slider moves away from the through hole, until the storage hole on the slider coincides with the ball outlet hole on the dehumidification tray, and the dehumidification ball in the storage hole rolls into the baffle of the dehumidification tray through the ball outlet hole. After the saturated dehumidifier bulbs are pushed into the drying circulation pipe, as more and more dehumidifier bulbs are pushed in, the saturated dehumidifier bulbs are sent to the middle section of the drying circulation pipe, which is the part behind the tinplate. At this time, since the electrical components will generate a lot of heat when in use, this heat will be absorbed by the galvanized plate and will heat the nearby drying circulation pipe, thereby drying the saturated dehumidifier bulbs. The water vapor generated by the drying will be dissipated through the steam outlet and taken away by the cooling fan. The new dehumidifier bulbs that enter the dehumidifier tray from the ball outlet will roll on the baffle and absorb the sinking water vapor, and the cycle will repeat. In this way, the saturated dehumidifier bulbs will be automatically replaced by dry ones, and the saturated dehumidifier bulbs will be dried by themselves. There is no need to replace the dehumidifier bulbs regularly, which reduces the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-17 A power distribution cabinet includes a cabinet body 2, which is a box structure with one side open. The cabinet body 2 serves as the main structure of the entire power distribution cabinet, protecting the internal electrical components and dehumidification components 6. It provides a closed environment to prevent external moisture and dust from entering, while supporting and fixing all internal components.

[0020] The cabinet body 2 is provided with a cabinet door 3, which is used to close the cabinet body 2 opening for easy maintenance and inspection of internal equipment. The cabinet door 3 is closed when not needed to protect the internal equipment, and opened when needed to perform maintenance or add equipment.

[0021] A dehumidification assembly 6 is provided at the inner bottom of the cabinet 2, and the dehumidification assembly 6 absorbs and removes moisture in the cabinet 2 through a dehumidification ball 7, so as to keep the cabinet 2 dry and prevent the electrical components from being damaged by moisture.

[0022] The dehumidification assembly 6 includes a dehumidification plate 62, and the side of the dehumidification plate 62 close to the outside of the cabinet 2 is higher than the side close to the inside of the cabinet 2. A zigzag-shaped baffle 66 is arranged inside the dehumidification plate 62. The dehumidification plate 62 serves as a rolling platform for the dehumidification ball 7, guiding the dehumidification ball 7 to roll and absorb moisture. The dehumidification ball 7 can roll in an orderly manner and evenly absorb moisture during the rolling process due to the inclination of the outside higher than the inside and the zigzag-shaped baffle 66. The baffle 66 forms a zigzag path in the dehumidification plate 62 to guide the dehumidification ball 7 to roll. The contact time between the dehumidification ball 7 and moisture is increased, thereby improving the dehumidification efficiency. In addition, the baffle 66 can also be used to receive the dehumidification ball 7 spit out from the ball outlet 625, and finally guide the saturated dehumidification ball 7 to accurately enter the ball inlet 626.

[0023] The dehumidification ball 7 is an activated alumina ball.

[0024] A ball outlet assembly 64 is provided on the left corner near the outside of the dehumidification tray 62, and a ball top assembly 65 is provided on the right corner near the inside of the dehumidification tray 62. A drying circulation pipe 63 is connected between the ball outlet assembly 64 and the ball top assembly 65. The ball outlet assembly 64 and the ball top assembly 65 are responsible for pushing the dehumidification ball 7 out of the drying circulation pipe 63 and pushing it back. The dehumidification ball 7 is recycled to ensure a continuous and effective dehumidification effect. The drying circulation pipe 63 is used to store and dry the dehumidification ball 7. The heat generated by the electrical components is used to dry the saturated dehumidification ball 7, and the water vapor is discharged through the steam outlet 631.

[0025] A motor assembly 61 is also provided on the outside of the top ball assembly 65, and the motor assembly 61 provides power for the ball outlet assembly 64 and the top ball assembly 65. The swing rod 613 is driven by the motor 611 to drive the ball outlet assembly 64 and the top ball assembly 65 to operate, thereby realizing the automatic replacement and drying of the dehumidification ball 7. The drying circulation pipe 63 is filled with dehumidification balls 7. The ball outlet assembly 64 pushes the dehumidification balls 7 in the drying circulation pipe 63 out of the left corner of the outer side of the dehumidification tray 62. The dehumidification balls 7 are guided to roll and absorb moisture through the baffle 66, and the top ball assembly 65 pushes the saturated dehumidification balls 7 back into the drying circulation pipe 63.

[0026] The cabinet 2 is provided with a galvanized plate 4, on which electrical components are mounted. The middle section of the drying circulation pipe 63 is located behind the galvanized plate 4, and the dehumidification ball 7 in the drying circulation pipe 63 is dried by the heat generated when the electrical components are used.

[0027] The motor assembly 61 includes a motor bracket 6526, the bottom of which is fixedly mounted on the bottom of the cabinet 2, and a motor 611 is arranged on the motor bracket 6526, which serves as a supporting structure for the motor 611, ensuring that the motor 611 is firmly mounted in the cabinet 2. The motor 611 provides a power source to drive the operation of the entire dehumidification cycle. The rotation of the motor shaft 614 drives the movement of the driving block 615 and the swing rod 613, thereby realizing the coordinated work of the ball outlet assembly 64 and the ball top assembly 65.

[0028] A driving block 615 is provided on the motor shaft 614 of the motor 611, and two swing rods 613 are sequentially mounted on the driving block 615. A matching groove 6131 is provided in the middle of the swing rod 613, and the matching groove 6131 and the driving block 615 cooperate with each other. The driving block 615 converts the rotational motion of the motor shaft 614 into the reciprocating swing of the swing rod 613. During the rotation process, the driving block 615 pushes the swing rod 613 to produce a reciprocating swing, thereby driving the operation of the ball output assembly 64 and the ball push assembly 65. The matching groove 6131 ensures a stable connection and synchronous motion between the swing rod 613 and the driving block 615.

[0029] One end of the swing rod 613 close to the motor 611 is rotatably connected to the hinge bar 6511 of the ball-pushing assembly 65, and the other end is fixedly rotatably connected to the inner wall of the cabinet 2. One end of the swing rod 613 away from the motor 611 is rotatably connected to one end of the connecting rod 641 of the ball-discharging assembly 64, and the other end is fixedly rotatably connected to the inner wall of the cabinet 2. The swing rod 613 is made to rotate on the inner wall of the cabinet 2. By rotating the connection point, the swing rod 613 can swing freely without leaving the structure of the cabinet 2, thereby completing the pushing and pushing back of the dehumidification ball 7.

[0030] A front foot seat 624 and a rear foot seat 623 are respectively provided at the front and rear of the bottom of the dehumidification tray 62. The height of the front foot seat 624 is greater than that of the rear foot seat 623. The front foot seat 624 and the rear foot seat 623 are used to support the dehumidification tray 62 and form a certain inclination angle. The height of the front foot seat 624 is greater than that of the rear foot seat 623, so that the front end of the dehumidification tray 62 is higher than the rear end, which helps the dehumidification ball 7 to move forward naturally during the rolling process, thereby effectively absorbing and discharging moisture.

[0031] The rear of the dehumidifying plate 62 is also provided with a mounting seat 1 621 and a mounting seat 2 622, which are respectively used to mount the two ends of the connecting rod 2 642, and the mounting seat 1 621 and the mounting seat 2 622 are provided with a limiting groove 6211. The limiting groove 6211 allows the connecting rod 2 642 to slide to a certain extent between the two.

[0032] A ball outlet hole 625 is provided on the side wall of the dehumidification tray 62 near the ball outlet assembly 64, and a ball inlet hole 626 is provided on the side wall of the dehumidification tray 62 near the top ball assembly 65. The ball outlet hole 625 and the ball inlet hole 626 serve as channels for the dehumidification ball 7 to enter the dehumidification tray 62 and be pushed out of the dehumidification tray 62, respectively. The ball outlet hole 625 is located on the side of the dehumidification tray 62 near the ball outlet assembly 64, and is used to push the dehumidification ball 7 in the drying circulation pipe 63 into the dehumidification tray 62 for dehumidification; the ball inlet hole 626 is located on the side of the dehumidification tray 62 near the top ball assembly 65, and is used to push the dehumidification ball 7 that has completed the dehumidification task back into the drying circulation pipe 63 for drying. The design of these two holes allows the dehumidification ball 7 to circulate between the dehumidification tray 62 and the drying circulation pipe 63.

[0033] The drying circulation pipe 63 is provided with a steam outlet 631. The steam outlet 631 allows the water vapor or moisture in the drying circulation pipe 63 to be discharged. During the drying process, the moisture on the dehumidification bulb 7 will be heated and evaporated into water vapor. The steam outlet 631 is provided to allow the water vapor to be smoothly discharged from the drying circulation pipe 63 to avoid the accumulation of water vapor in the pipe and affect the drying effect. Through the steam outlet 631, the water vapor can be effectively discharged to the outside of the distribution cabinet, thereby maintaining a dry environment in the drying circulation pipe 63 and ensuring the drying effect of the dehumidification bulb 7.

[0034] The ball outlet assembly 64 includes a sliding frame 646, which is fixedly mounted on the outer side of the side of the dehumidification tray 62 where the ball outlet hole 625 is located, and the sliding frame 646 serves as a support and guide structure for the slider 645. The sliding frame 646 is fixedly mounted on the side of the dehumidification tray 62, providing a stable sliding platform for the slider 645.

[0035] The sliding frame 646 is provided with a slide groove 6462 and a through hole 6461, and the through hole 6461 is connected to one end of the drying circulation pipe 63. The slide groove 6462 and the through hole 6461 provided on the sliding frame 646 are respectively used to limit the sliding direction of the slider 645 and to achieve the connection with the drying circulation pipe 63. The through hole 6461 allows the dehumidification ball 7 to enter the sliding frame 646 from the drying circulation pipe 63 and then be pushed into the dehumidification tray 62.

[0036] A slider 645 is slidably installed in the sliding frame 646. A limit rod 6451 and a storage hole 6452 are provided on the slider 645. The limit rod 6451 is slidably installed in the slide groove 6462. The storage hole 6452 corresponds to the through hole 6461. The slider 645 can intermittently carry and push the dehumidification ball 7. The slider 645 slides in the sliding frame 646, temporarily stores the dehumidification ball 7 through the storage hole 6452 provided thereon, and pushes the dehumidification ball 7 to the ball outlet hole 625 of the dehumidification tray 62 during the sliding process. The limit rod 6451 prevents the slider 645 from escaping from the sliding frame 646. The storage hole 6452 temporarily stores the dehumidification ball 7. When the dehumidification ball 7 enters the through hole 6461 from the drying circulation pipe 63, it will be temporarily stored in the storage hole 6452 of the slider 645, waiting to be pushed into the dehumidification tray 62.

[0037] The bottom of the slider 645 is provided with a connecting column 6453, on which one end of the connecting rod 4 644 is provided, and the other end of the connecting rod 4 644 is sequentially connected to the connecting rod 3 643, the connecting rod 2 642 and the connecting rod 1 641, and the two ends of the connecting rod 2 642 are respectively provided with mounting columns 6421, which are respectively installed in the limiting grooves 6211 of the mounting seat 1 621 and the mounting seat 2 622, one end of the connecting rod 1 641 is connected to the connecting rod 2 642, and the other end is connected to one end of the swing rod 613 away from the motor 611. The connecting column 6453 transmits power and motion to the connecting rod 1 641, the connecting rod 2 642, the connecting rod 3 643 and the connecting rod 4 644. These connecting rods are connected to each other to transmit the motion of the swing rod 613 away from the motor 611 to the slider 645. When the swing rod 613 swings, its movement is transmitted to the slider 645 through the connecting rod series, so that the slider 645 slides in the sliding frame 646, thereby pushing the dehumidification ball 7. The mounting column 6421 on the second connecting rod 642 is installed in the limiting groove 6211 of the first mounting seat 621 and the second mounting seat 622, which plays a role of fixing and guiding, ensuring that the connecting rod series can move along the predetermined track.

[0038] The top ball assembly 65 includes a top ball component 1 651 and a top ball component 2 652. The top ball component 2 652 is fixedly mounted on the outer side of the side of the dehumidification tray 62 where the goal hole 626 is located. The top ball component 1 651 is slidably arranged below the top ball component 2 652. The top ball component 2 652 is also provided with a transition component 653, and the transition component 653 is connected to the other end of the drying circulation pipe 63. The top ball component 1 651 includes a receiving seat 6513, and the receiving seat 6513 is used to receive the dehumidification ball 7 entering the top ball component 1 651 from the goal hole 626. The receiving seat 6513 is used to receive the dehumidification ball 7 entering from the goal hole 626. When the dehumidification ball 7 rolls out of the goal hole 626 of the dehumidification tray 62, the receiving seat 6513 can accurately capture the saturated dehumidification ball 7 to prevent it from falling or deviating from the predetermined path.

[0039] The first ball pusher 651 is provided with a limit hole 6512, which limits the position of the first ball pusher 651 during the sliding process to ensure that it moves on the correct track. The limit hole 6512 cooperates with the limit column 6524 on the second ball pusher 652 to prevent the first ball pusher 651 from deflecting or over-moving during sliding through physical restrictions, thereby ensuring the accuracy and stability of the ball pusher action.

[0040] A hinge bar 6511 is also provided on the top ball member 651, and the hinge bar 6511 is connected to one end of the swing rod 613 near the motor 611. The hinge bar 6511 connects the top ball member 651 and the swing rod 613 to achieve mechanical transmission. The hinge bar 6511 is connected to the swing rod 613 in a hinged manner, so that when the swing rod 613 is driven by the motor 611 to swing, it can drive the top ball member 651 to slide. This connection method allows the top ball member 651 to move in the vertical direction to push the dehumidification ball 7 upward to the desired position.

[0041] The top ball assembly 652 includes a bracket 6526, which is fixedly mounted on the outside of the side of the dehumidification disk 62 where the ball hole 626 is located. The bracket 6526 serves as the support base of the entire top ball assembly 652 and is fixedly mounted on the outside of the side of the dehumidification disk 62. The bracket 6526 provides a stable installation platform, so that the transition piece 653, the sleeve 6521, the check rod 6522 and other components can be stably installed in the correct position.

[0042] A transition piece 653 is installed on the upper part of the bracket 6526. The transition piece 653 serves as a transition channel for the dehumidification ball 7 to be transferred from the dehumidification tray 62 to the drying circulation pipe 63 through the top ball component 1 651 and the top ball component 2 652. The design of the transition piece 653 enables the dehumidification ball 7 to be smoothly pushed from the top ball component 652 into the drying circulation pipe 63, thereby preventing the dehumidification ball 7 from being stuck or falling during the transfer process.

[0043] The two sides of the bracket 6526 are provided with sleeves 6521 which are inclined upwards, and a check rod 6522 is slidably installed inside the sleeve 6521. A stopper 6523 is provided at the end of the check rod 6522, and a spring 6525 is provided between the check rod 6522 and the sleeve 6521. The sleeve 6521 provides a sliding track for the check rod 6522 to limit its movement direction. The space inside the sleeve 6521 allows the check rod 6522 to slide freely inside it, but at the same time limits the movement direction and range of the check rod 6522 by its shape and size. The check rod 6522 prevents the dehumidification ball 7 from sliding in the reverse direction during the transfer process. The end of the check rod 6522 is provided with a stopper 6523. When the dehumidification ball 7 tries to slide in the reverse direction, the stopper 6523 will contact it and prevent it from moving further. In this way, the check rod 6522 ensures that the dehumidification ball 7 can only be pushed upward, thereby improving the stability and reliability of the transfer process. The spring 6525 provides a restoring force for the anti-return rod 6522 to ensure that it can return to the initial position when no external force is applied. The spring 6525 is connected between the anti-return rod 6522 and the sleeve 6521. When the anti-return rod 6522 is subjected to the lifting force of the dehumidification ball 7, the spring 6525 will be compressed. Once the dehumidification ball 7 passes, the elastic force of the spring 6525 will cause the anti-return rod 6522 to quickly return to the initial position, preparing for the next anti-return action.

[0044] The bracket 6526 is also provided with a limit column 6524, which is inserted into the limit hole 6512. The limit column 6524 cooperates with the limit hole 6512 on the top ball part 1 651 to limit the movement range of the top ball part 1 651.

[0045] The transition piece 653 includes a connecting pipe 6532, which serves as a passage for the dehumidifying ball 7 to be transferred from the top ball assembly 65 to the drying circulation pipe 63. The connecting pipe 6532 provides a path so that the dehumidifying ball 7 can be smoothly pushed from the top ball assembly 65 into the drying circulation pipe 63. A mounting block 6531 is provided on the outer side of the connecting pipe 6532, and the mounting block 6531 is fixedly installed in the bracket 6526. The mounting block 6531 firmly mounts the connecting pipe 6532 on the bracket 6526. The mounting block 6531 serves as a connecting medium between the connecting pipe 6532 and the bracket 6526, and is fixedly installed in the bracket 6526 through the mounting block 6531, so that the connecting pipe 6532 can maintain a stable position and direction.

[0046] The bottom of the connecting tube 6532 is located inside the bracket 6526. Notches 6533 are provided on both sides of the bottom of the connecting tube 6532. The notches 6533 are abutted with the blocking member 6523. The notches 6533 provide abutment positions for the blocking member 6523, and allow the blocking member 6523 to extend into the connecting tube 6532 to limit the moving direction of the dehumidification ball 7 during the transfer process. The blocking member 6523 cooperates with the notches 6533 to limit the moving direction of the dehumidification ball 7 during the transfer process.

[0047] A cooling fan 1 is provided on the top of the cabinet 2, and a cabinet foot 5 is provided on the bottom of the cabinet 2. The cooling fan 1 can bring the air inside the cabinet 2 out of the cabinet 2. The main function of the cooling fan 1 is to promote the air circulation inside the cabinet 2, help dissipate heat, and carry out the water vapor evaporated from the drying circulation pipe 63. The main function of the cabinet foot 5 is to support the cabinet 2 so that it can be placed firmly on the ground and maintain a certain ground clearance. A certain gap is maintained between the cabinet 2 and the ground. This gap is not only conducive to air circulation and reduces the impact of ground moisture on the cabinet 2, but also facilitates cleaning and maintenance.

[0048] Working principle: The electrical components in the distribution cabinet are installed on the galvanized plate 4. A number of dehumidification balls 7 are rolled on the baffle 66 of the dehumidification plate 62. These dehumidification balls 7 can absorb the water vapor sinking in the distribution cabinet. When the dehumidification balls 7 reach saturation, they will gradually be arranged at the ball hole 626, waiting for the top ball assembly 65 to send the saturated dehumidification balls 7 into the drying circulation pipe 63 for drying. The saturated dehumidification ball 7 enters the receiving seat 6513 through the ball hole 626. At this time, the top ball piece 651 slides downward and separates from the top ball piece 652 under the drive of the motor 611 and the swing rod 613. As the motor 611 continues to rotate, the top ball piece 651 with the dehumidification ball 7 gradually rises and approaches the top ball piece 652. The dehumidification ball 7 located on the receiving seat 6513 pushes the stopper 6523 to both sides, and the check rod 6522 retracts into the sleeve 6521, and the dehumidification ball 7 enters the connecting pipe 6532. Once the dehumidification ball 7 passes through the stopper 6523, the low stopper will be reset under the action of the spring 6525 to prevent the dehumidification ball 7 that has entered the connecting pipe 6532 from falling back. Since the drying circulation pipe 63 is tightly filled with dehumidification balls 7, when a saturated dehumidification ball 7 is pushed in from one side of the drying circulation pipe 63, a dried dehumidification ball 7 will be ejected from the other side of the drying circulation pipe 63. Under the action of the motor 611 and the swing rod 613, when the ball pusher 1 651 slides downward, the swing rod 613 connected to the connecting rod 1 641 pulls the connecting rod 1 641, thereby pulling the connecting rod 2 642, the connecting rod 3 643, and the connecting rod 4 644, and the connecting rod 4 644 pulls the slider 645, so that the storage hole 6452 on the slider 645 and the through hole 6461 on the sliding frame 646 overlap each other, and at this time, the dehumidification ball 7 in one end of the drying circulation pipe 63 that is interconnected with the through hole 6461 enters the storage hole 6452 through the through hole 6461. While the ball-pushing member 651 rises to push a dehumidification ball 7 into the drying circulation pipe 63, under the action of the motor 611 and the swing rod 613, the swing rod 613 pushes the connecting rod 1 641, thereby pushing the connecting rod 2 642, the connecting rod 3 643, and the connecting rod 4 644. The connecting rod 4 644 pushes the slider 645, so that the slider 645 moves away from the through hole 6461 until the storage hole 6452 on the slider 645 coincides with the ball outlet hole 625 on the dehumidification tray 62. At this time, the dehumidification ball 7 located in the storage hole 6452 rolls onto the baffle 66 of the dehumidification tray 62 through the ball outlet hole 625. After the saturated dehumidification bulb 7 is pushed into the drying circulation pipe 63, as more and more dehumidification bulbs 7 are pushed in, the saturated dehumidification bulbs 7 are sent to the middle section of the drying circulation pipe 63, that is, the part located behind the tinplate. At this time, since the electrical components will generate a large amount of heat when in use, this heat will be absorbed by the galvanized plate 4 and will heat the nearby drying circulation pipe 63, thereby drying the saturated dehumidification bulbs 7 therein. The water vapor generated by the drying is dissipated through the steam outlet 631 and is taken away by the cooling fan 1.The new dehumidification ball 7 entering the dehumidification tray 62 from the ball outlet hole 625 rolls on the baffle 66 and absorbs the sinking water vapor, repeating the cycle.
