Description

Technical Field

[0001] This invention relates to the field of distribution box equipment with protective structure, specifically to a distribution box with protective structure. Background Technology

[0002] Distribution boxes are characterized by their small size, easy installation, unique technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. They serve as the control center for the rational distribution of electrical energy among various components in the power supply line and are reliably designed to receive power from upstream sources.

[0003] An existing type of distribution box with a protective structure cannot perform clamping, fixing, or vibration damping when protecting the distribution box. As a result, it is prone to damage from impacts, which increases the danger of the machine during operation. The distribution box is easily damaged, resulting in wasted money and reduced lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a distribution box with a protective structure to solve the problems mentioned in the background art.

[0007] Furthermore, there are four shock-absorbing blocks. The elastic plate penetrates the protective box and extends to the surface of the fixed plate. The surface of the rubber plate is adapted to the surface of the main body of the distribution box. The long rod penetrates the protective sliding plate and extends to the outer end of the protective sliding plate. The end of the elastic rod away from the protective sliding plate is fixedly connected to the surface of the long rod.

[0008] Furthermore, the push rod is located above the protective box, the surface of the fixed protective plate is adapted to the upper surface of the main body of the distribution box, the pressure plate is located above the main body of the distribution box, the bottom of the pressure plate is adapted to the top of the main body of the distribution box, and the end of the pressure block away from the pressure plate contacts the top of the protective sliding plate.

[0009] Furthermore, the cleaning and heat dissipation device includes a support frame, the surface of which is fixedly connected to the surface of the insulating box. A heat dissipation frame is fixedly connected to the surface of the insulating box, a rainproof plate is fixedly connected to the upper surface of the heat dissipation frame, a heat dissipation plate is fixedly connected to the inner wall of the heat dissipation frame, a partition is fixedly connected to the inner wall of the insulating box, a cleaning door is provided on the surface of the partition, heat dissipation holes are provided on the inner wall of the insulating box, a motor is fixedly connected to the inner wall of the support frame, a rotating rod is fixedly connected to the output end of the motor, a fan blade is fixedly connected to the surface of the rotating rod, a retractable rod is fixedly connected to the inner wall of the insulating box, an elongated plate is hinged to the output end of the bidirectional electric push rod, a soft brush is hinged to the end of the elongated plate away from the bidirectional electric push rod, a push-pull rod is fixedly connected to the lower surface of the soft brush, and a cleaning scraper is fixedly connected to the bottom of the soft brush.

[0010] Furthermore, the number of heat dissipation holes is several, the end of the retractable rod away from the insulating box is fixedly connected to the surface of the soft brush, the surface of the soft brush is adapted to the surface of the heat dissipation hole, the rotating rod passes through the insulating box and extends to the outer end of the fan blade, and the bottom of the cleaning scraper is adapted to the top of the partition.

[0011] Furthermore, the loading and unloading device includes a guide rail, the bottom of which is fixedly connected to the top of the partition, a hinge plate hinged to the top of the push rod, a fixed pressing plate fixedly connected to the inner wall of the insulating box, a movable pressing block hinged to the end of the hinge plate away from the push rod, a circular telescopic rod fixedly connected to the inner wall of the guide rail, a movable wheel slidably connected to the inner wall of the guide rail, and a spring sheet fixedly connected to the inner wall of the guide rail.

[0012] Furthermore, the hinge plate is located above the push rod, the end of the movable extrusion block is adapted to the surface of the fixed extrusion plate, the end of the movable wheel away from the guide rail is fixedly connected to the bottom of the protective box, the end of the circular telescopic rod away from the guide rail is fixedly connected to the surface of the movable wheel, and the end of the spring piece away from the guide rail is in contact with the surface of the movable wheel.

[0013] The present invention has the following beneficial effects: When the main body of the distribution box is placed on top of the placement plate, the bidirectional electric push rod is activated. The output end drives the support blocks to move closer or further apart. When the support blocks move closer, they cause the fixing plate and rubber plate to move closer together, clamping and fixing the main body of the distribution box. Simultaneously, when the support blocks move closer, the telescopic rod drives the fixed protective plates to move closer together, providing secondary fixation to the main body of the distribution box and ensuring the machine's protection. When the fixed protective plates move closer, the inclined plate presses against the pressure plate, making the main body of the distribution box more stable and preventing displacement that could cause damage. When the pressure plate moves downwards, it presses the protective sliding plate against the surface of the long rod via the pressure block, thus protecting the main body of the distribution box and preventing it from falling due to collisions. The elastic rod makes its position more stable during movement. At the same time, when the fixed protective plates move away from each other, the inclined plate pulls the pressure plate upwards. When the pressure plate moves upwards, it causes the pressure block to detach from the protective sliding plate. At this time, the protective sliding plate will be pulled upwards by the elastic rod, which facilitates the maintenance of the main body of the distribution box. The vibration damping block will dampen the vibration of the main body of the distribution box when it shakes due to collisions, preventing damage caused by bumps.

[0014] When the motor is turned on, the output end drives the fan blades to rotate via a rotating rod, thereby dissipating heat from the main body of the distribution box and extending its service life. Simultaneously, the heat dissipation holes and heat sink improve heat dissipation efficiency, and the rainproof plate allows rainwater to quickly slide off, preventing accumulation on the top of the insulating box. When the bidirectional electric push rod is opened, a long plate presses the soft brush, causing it to move across the surface of the heat dissipation holes, cleaning them and preventing dust accumulation that could clog them and affect heat dissipation. The retractable rod ensures the soft brush remains in a more stable position during movement. As the soft brush cleans the heat dissipation holes, a large amount of dust falls into the interior of the partition for collection. The soft brush also moves a cleaning scraper, cleaning and scraping the surface of the partition, preventing dust accumulation from affecting the normal operation of the soft brush over time.

[0015] When the push rods move away from each other, the invention pulls the hinge plate, causing the moving extrusion block to press against the fixed extrusion plate. This allows the protective box to move inside the guide rail via the moving wheels, enabling it to be quickly moved out of the insulation box for easy maintenance and disassembly. The circular telescopic rod makes the position of the moving wheels more stable when they move.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] A push rod 31 is fixedly connected to the output end of the bidirectional electric push rod 30. A support block 32 is fixedly connected to the end of the push rod 31 away from the bidirectional electric push rod 30. When the support blocks 32 approach each other, they will drive the fixing plate 24 and the rubber plate 25 to approach each other, so as to clamp and fix the main body 3 of the distribution box. A telescopic rod 33 is fixedly connected to the inner wall of the support block 32. The telescopic rod 33 drives the fixed protective plate 34 to approach each other, so as to fix the main body 3 of the distribution box for a second time. A fixed protective plate 34 is fixedly connected to the end of the telescopic rod 33 away from the support block 32. When the fixed protective plates 34 approach each other, they will press the pressure plate 36 through the inclined plate 35 to press the main body 3 of the distribution box, so that the distribution box... The main body 3 is more stable. The end of the fixed protective plate 34 away from the telescopic rod 33 is hinged to an inclined plate 35. The inclined plate 35 pulls the pressure plate 36 to move upward. When the pressure plate 36 moves upward, it will drive the pressure block 37 to disengage from the protective sliding plate 27. At this time, the protective sliding plate 27 will be pulled upward by the elastic rod 28, which facilitates the maintenance of the main body 3 of the distribution box. The end of the inclined plate 35 away from the fixed protective plate 34 is hinged to a pressure plate 36. When the pressure plate 36 moves downward, it will squeeze the protective sliding plate 27 on the surface of the long rod 26 through the pressure block 37 to protect the main body 3 of the distribution box. The pressure block 37 is fixedly connected to the surface of the pressure plate 36.

[0023] There are four shock absorbers 21. The spring plate 23 passes through the protective box 22 and extends to the surface of the fixed plate 24.

A cleaning door 45 is opened on the surface of the partition 44. Heat dissipation holes 46 are opened on the inner wall of the insulating box 1. The heat dissipation holes 46 and the heat dissipation plate 43 improve heat dissipation efficiency. A motor 47 is fixedly connected to the inner wall of the support frame 40. When the motor 47 is turned on, its output end drives the fan blades 49 to rotate through the rotating rod 48, thereby dissipating heat from the main body of the distribution box 3. The output end of the motor 47 is fixedly connected to... A rotating rod 48 has a fan blade 49 fixedly connected to its surface. A retractable rod 50 is fixedly connected to the inner wall of the insulating housing 1. The retractable rod 50 makes the position of the soft brush 52 more stable when it moves. A long plate 51 is hinged to the output end of the bidirectional electric push rod 30. The long plate 51 squeezes the soft brush 52 to move it on the surface of the heat dissipation hole 46, so that it cleans the heat dissipation hole 46. The end of the long plate 51 away from the bidirectional electric push rod 30 is hinged to the soft brush 52. When the soft brush 52 cleans the heat dissipation hole 46, a lot of dust will fall into the interior of the partition 44 for collection. A push-pull rod 53 is fixedly connected to the lower surface of the soft brush 52. A cleaning scraper 54 is fixedly connected to the bottom of the soft brush 52. The cleaning scraper 54 moves to clean and scrape the surface of the partition 44.

[0026] There are several heat dissipation holes 46. The end of the retractable rod 50 away from the insulating box 1 is fixedly connected to the surface of the soft brush 52. The surface of the soft brush 52 is adapted to the surface of the heat dissipation hole 46. The rotating rod 48 passes through the insulating box 1 and extends to the outer end of the fan blade 49. The bottom of the cleaning scraper 54 is adapted to the top of the partition 44.

[0027] The loading and unloading device 6 includes a guide rail 60, the bottom of which is fixedly connected to the top of the partition 44. The top of the push rod 31 is hinged to a hinge plate 61. Pulling the hinge plate 61 causes the moving extrusion block 63 to press against the fixed extrusion plate 62, thereby causing the protective box 22 to move inside the guide rail 60 via the moving wheel 65. The inner wall of the insulating box 1 is fixedly connected to the fixed extrusion plate 62. The end of the hinge plate 61 away from the push rod 31 is hinged to the moving extrusion block 63. The inner wall of the guide rail 60 is fixedly connected to a circular telescopic rod 64, which makes the position of the moving wheel 65 more stable when it moves. The inner wall of the guide rail 60 is slidably connected to the moving wheel 65, and the inner wall of the guide rail 60 is fixedly connected to a spring piece 66.

[0028] The hinge plate 61 is located above the push rod 31. The end of the movable extrusion block 63 is adapted to the surface of the fixed extrusion plate 62. The end of the movable wheel 65 away from the guide rail 60 is fixedly connected to the bottom of the protective box 22. The end of the circular telescopic rod 64 away from the guide rail 60 is fixedly connected to the surface of the movable wheel 65. The end of the spring piece 66 away from the guide rail 60 is in contact with the surface of the movable wheel 65.

[0029] In use, when the main body 3 of the distribution box is placed above the placement plate 20, the bidirectional electric push rod 30 is activated. The output end will drive the support blocks 32 to move closer or further apart via the push rod 31. When the support blocks 32 move closer together, they will drive the fixing plate 24 and the rubber plate 25 to move closer together, thus clamping and fixing the main body 3 of the distribution box. At the same time, when the support blocks 32 move closer together, they will drive the fixed protective plate 34 to move closer together via the telescopic rod 33, thus providing secondary fixation for the main body 3 of the distribution box and ensuring the protection of the machine. When the fixed protective plate 34 moves closer together, the inclined plate 35 will press the pressure plate 36 to press the main body 3 of the distribution box, making the position of the main body 3 of the distribution box more stable and preventing spillage. The current offset causes damage. When the pressure plate 36 moves downward, it will press the protective sliding plate 27 against the surface of the long rod 26 through the pressure block 37, thus protecting the main body of the distribution box 3 and preventing it from falling due to collision. The elastic rod 28 makes its position more stable when it moves. At the same time, when the fixed protective plates 34 move away from each other, the inclined plate 35 will pull the pressure plate 36 upward. When the pressure plate 36 moves upward, it will drive the pressure block 37 to detach from the protective sliding plate 27. At this time, the protective sliding plate 27 will be pulled upward by the elastic rod 28, which facilitates the maintenance of the main body of the distribution box 3. The vibration damping block 21 will dampen the vibration of the main body of the distribution box 3 when it shakes due to collision. To prevent damage from impacts, the motor 47 operates by rotating the fan blades 49 via the lever 48, thus cooling the main body 3 of the distribution box and extending its service life. Simultaneously, the heat dissipation holes 46 and heat sink 43 improve heat dissipation efficiency. The rainproof plate 42 allows rainwater to quickly slide off, preventing accumulation on the top of the insulating box 1. When the bidirectional electric push rod 30 is activated, the elongated plate 51 presses the soft brush 52, causing it to move across the surface of the heat dissipation holes 46, cleaning them and preventing dust accumulation that could block heat dissipation. The retractable lever 50 ensures the soft brush 52 remains in a more stable position during movement. When the soft brush 52 cleans the heat dissipation holes 46, a large amount of dust will fall into the interior of the partition 44 for collection. The soft brush 52 drives the cleaning scraper 54 to move together, so that it can clean and scrape the surface of the partition 44, avoiding the problem of dust accumulation affecting the normal operation of the soft brush 52. When the push rods 31 move away from each other, they will pull the hinge plate 61 to make the moving pressing block 63 press and fix the pressing plate 62, so that the protective box 22 can move inside the guide rail 60 through the moving wheel 65, so that it can be quickly moved out of the interior of the insulating box 1 for easy maintenance and disassembly. The circular telescopic rod 64 will make the position of the moving wheel 65 more stable when it moves.
