Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to an integrated heat dissipation and insulation distribution box. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Existing distribution boxes are complex in structure, cumbersome to assemble, and have poor heat dissipation and practicality. Furthermore, existing distribution boxes are prone to dust accumulation due to poor ventilation, which further hinders heat dissipation. Therefore, it is essential to design a distribution box that integrates heat dissipation and insulation, offering convenient assembly and disassembly, and superior heat dissipation. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated heat dissipation and insulation distribution box to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a heat dissipation and insulation integrated distribution box, including a rear fixed shell, an electrical mounting plate connected to the top of the rear fixed shell by threads, a front shield shell connected to the inside of the electrical mounting plate by riveting, a power supply plug connected to one side of the electrical mounting plate by riveting, a cooling mechanism provided on the sides of the rear fixed shell and the electrical mounting plate, and a dust removal mechanism connected to the top of the rear fixed shell by riveting. The front shield shell is installed into the electrical mounting plate, the electrical mounting plate fixes it, the rear fixed shell is installed, and finally the power supply plug is installed. The cooling mechanism dissipates the heat generated by the front shield shell, and the dust removal mechanism cleans the dust.

[0006] According to the above technical solution, the cooling mechanism includes a plurality of cooling holes evenly arranged on the rear fixed shell and the electrical mounting plate. A semiconductor cooling chip is threadedly connected to the top of the rear fixed shell. Both ends of the semiconductor cooling chip are connected to heat transfer copper tubes by insertion. One end of the heat transfer copper tube is connected to the corresponding cooling hole by clearance fit. When the front shield shell generates heat, the cooling holes of the electrical mounting plate and the rear fixed shell are connected to the outside air for heat dissipation. When the heat generation is too high, the semiconductor cooling chip absorbs heat at the same time and transfers the heat to the corresponding connected cooling hole through the heat transfer copper tube to accelerate heat dissipation.

[0007] According to the above technical solution, the dust removal mechanism includes a sliding square hole. The top support of the rear fixed shell has a sliding square hole. Electromagnets are riveted to both ends of the sliding square hole. One side of the two electromagnets is connected to the power supply plug through a circuit. A friction dust removal plate is connected to the inner wall of the sliding square hole through a clearance fit. A permanent magnet is connected to the center of the friction dust removal plate through a clearance fit. When the power supply plug is pressed and the power is turned on, the two electromagnets at both ends of the sliding square hole are energized to generate a magnetic field. The permanent magnet repels the magnetic field and reciprocates inside the sliding square hole, driving the friction dust removal plate to move, thereby cleaning the contact cooling holes.

[0008] According to the above technical solution, the inner wall of the electrical mounting plate is connected with hollow screw-hole columns by welding. Moving blocks are slidably connected to both sides of the hollow screw-hole columns. An elastic element is connected to the top of each moving block via tenon and mortise. One end of the elastic element is connected to an arc-shaped locking block via tenon and mortise. An elastic traction band is threaded to the bottom of the arc-shaped locking block. The elastic traction band is connected to a guide wheel via contact. One end of the moving block is threaded to a hollow connecting column. One end of the hollow connecting column is hinged to a shaped contact wheel. One end of the shaped contact wheel is also threaded to an elastic element. A winding rod is provided at one end of the shaped contact wheel. The winding rod cooperates with the elastic traction band. After the current shielding shell is installed on the upper plate, the hollow screw-hole columns on both sides... The arc-shaped locking block fixes the front shield shell. When the front shield shell is removed, the elastic traction belt connects to the irregular contact wheel through the winding rod. The elastic traction belt pulls the irregular contact wheel to rotate, and the elastic element at the irregular contact wheel contracts under force. The irregular contact wheel drives the hollow connecting column to move down, and the hollow connecting column pulls the moving block to one end of the slide. At the same time, the elastic element on the moving block contracts, and the elastic element pulls the arc-shaped locking block to the left. When the elastic traction belt is released, the elastic element resets and rotates the irregular contact wheel in the opposite direction, pushing the hollow connecting column to move up. The moving block moves up, and at the same time, the elastic element at the moving block is no longer under force and resets, pushing the arc-shaped locking block to the right. During the rightward movement of the arc-shaped locking block, it also moves up and pushes the front shield shell to move, thereby pushing one end of the front shield shell out of the upper plate.

[0009] According to the above technical solution, one end of the elastic traction belt is connected to a winding reel via a thread, one end of the winding reel is connected to an electrical mounting plate via a bearing, and one end of the winding reel is connected to an external stud via a bearing. Torsional contact blocks are provided on both sides of the electrical mounting plate. The external stud cooperates with the torsional contact block. When the torsional contact block is pressed, the lower thread of the torsional contact block engages with the external stud, causing the external stud to rotate, thereby causing the winding reel to rotate. The elastic traction belt rotates and winds around the winding reel, thereby realizing the displacement of the elastic traction belt.

[0010] According to the above technical solution, the rear fixing shell and the electrical mounting plate are provided with grooves on all four sides, and two grooves are connected in a cooperating manner.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention,

[0012] (1) By setting a cooling mechanism, the front shield shell generates heat during operation, and the cooling holes of the electrical mounting plate and the rear fixed shell are connected to the outside air for heat dissipation. When the heat generation is too high, the semiconductor cooling chip absorbs heat at the same time and transfers the heat to the corresponding connecting cooling hole through the heat transfer copper tube to accelerate heat dissipation. The existing structure uses a fan for heat dissipation, which will generate noise and is complicated to install and has poor effect. The above steps achieve silent heat dissipation and improve the heat dissipation effect.

[0013] (2) By setting up a dust removal mechanism, after pressing the power plug and turning on the power, the two electromagnets at both ends of the sliding square hole are energized to generate a magnetic field. The permanent magnet repels the magnetic field and moves back and forth inside the sliding square hole, driving the friction dust removal plate to move, thereby cleaning the contact cooling hole. The existing structure requires manual cleaning of accumulated dust, and if the cleaning is not timely, the heat dissipation effect will be reduced. Through the above steps, the heat dissipation effect is guaranteed and manpower is saved.

[0014] (3) By setting a torsion contact block and an arc-shaped locking block, after the front shield shell is installed on the upper plate, the arc-shaped locking blocks on both sides of the outer stud fix the front shield shell. Pressing down the torsion contact block causes the lower end thread of the torsion contact block to engage with the outer stud, driving the outer stud to rotate, thereby driving the winding disc to rotate. The elastic traction belt rotates and winds around the winding disc, thereby realizing the displacement of the elastic traction belt. Because the elastic traction belt is connected to the irregular contact wheel by winding with the winding rod, the elastic traction belt pulls the irregular contact wheel to rotate. The elastic element at the irregular contact wheel is compressed by force, and the irregular contact wheel drives the hollow connecting column to move down. The hollow connecting column pulls the moving block down. Move to one end of the chute, and at the same time, the elastic element on the moving block of the elastic traction belt contracts. The elastic element pulls the arc-shaped locking block to the left. Release the elastic traction belt, and the elastic element resets, causing the irregular contact wheel to rotate in the opposite direction, pushing the hollow connecting column to move upward. The moving block moves upward, and at the same time, the elastic element at the moving block is no longer under force and resets, pushing the arc-shaped locking block to the right. During the rightward movement of the arc-shaped locking block, it also moves upward and pushes the front shield shell to move, thereby pushing one end of the front shield shell out of the upper plate. Through the above steps, the stability of the front shield shell is strengthened, poor contact caused by improper installation is prevented, and the inconvenience of disassembling the front shield shell is solved.

The front shield shell 3 is installed into the electrical mounting plate 2, the electrical mounting plate 2 fixes it, the rear fixed shell 1 is installed, and finally the power supply plug 4 is installed. The cooling mechanism 5 dissipates the heat generated by the electrical components inside the front shield shell 3, and the dust removal mechanism 6 cleans the dust.

[0025] The cooling mechanism 5 includes a number of cooling holes 7 evenly arranged on the rear fixed shell 1 and the electrical mounting plate 2. The top of the rear fixed shell 1 is connected to a semiconductor cooling chip 8 by a thread. Both ends of the semiconductor cooling chip 8 are connected to heat transfer copper tubes 9 by plug-in connection. One end of the heat transfer copper tube 9 is connected to the corresponding cooling hole 7 by a clearance fit. When the front shield shell 3 works, it generates heat. The cooling holes 7 of the electrical mounting plate 2 and the rear fixed shell 1 are connected to the outside air to dissipate heat. When the heat generation is too high, the semiconductor cooling chip 8 absorbs heat at the same time and transfers the heat to the corresponding connected cooling hole 7 through the heat transfer copper tube 9 to accelerate heat dissipation.

[0026] The top support of the rear fixed shell 1 has a sliding square hole 10. Electromagnets 11 are riveted to both ends of the sliding square hole 10. One side of the two electromagnets 11 is connected to the power supply plug 4 through a circuit. Friction dust removal plate 12 is connected to the inner wall of the sliding square hole 10 through a gap fit. A permanent magnet 24 is connected to the center of the friction dust removal plate 12 through a gap fit. When the power supply plug 4 is pressed and the power is turned on, the two electromagnets 11 at both ends of the sliding square hole 10 are energized to generate a magnetic field. The permanent magnet 24 repels the magnetic field and reciprocates inside the sliding square hole 10, driving the friction dust removal plate 12 to move, thereby cleaning the contact cooling hole 7.

[0027] The inner wall of the electrical mounting plate 2 is welded with hollow screw-hole columns 13. Moving blocks 14 are slidably connected to both sides of the hollow screw-hole columns 13. An elastic element 15 is tenon-jointed to the top of the moving blocks 14. One end of the elastic element 15 is tenon-jointed to an arc-shaped locking block 16. An elastic traction belt 17 is threaded to the bottom of the arc-shaped locking block 16. The elastic traction belt 17 is connected to a guide wheel via a contact connection. One end of the moving blocks 14 is threadedly connected to a hollow connecting column 18. One end of the hollow connecting column 18 is hinged to a shaped contact wheel 19. One end of the shaped contact wheel 19 is also threadedly connected to the elastic element 15. A winding rod 20 is provided at one end of the shaped contact wheel 19. The winding rod 20 cooperates with the elastic traction belt 17. After the front shielding shell 3 is installed on the upper plate 2, the arc-shaped locking blocks 16 on both sides of the hollow screw-hole columns 13 fix the front shielding shell 3. The front shielding shell 3 can then be removed. When the cover is blocked, the elastic traction belt 17 is connected to the irregular contact wheel 19 by winding with the winding rod 20. The elastic traction belt 17 pulls the irregular contact wheel 19 to rotate. The elastic element 15 at the irregular contact wheel 19 is compressed by force. The irregular contact wheel 19 drives the hollow connecting column 18 to move down. The hollow connecting column 18 pulls the moving block 14 to move down to one end of the slide. At the same time, the elastic element 15 on the moving block 14 of the elastic traction belt 17 contracts. The elastic element 15 pulls the arc-shaped locking block 16 to move to the left. The elastic traction belt 17 is released. The elastic element 15 resets and rotates the irregular contact wheel 19 in the opposite direction. It pushes the hollow connecting column 18 to move up. The moving block 14 moves up. At the same time, the elastic element 15 at the moving block 14 is no longer compressed and resets. It pushes the arc-shaped locking block 16 to move to the right. During the process of the arc-shaped locking block 16 moving to the right, it also moves up and pushes the front cover to move, thereby pushing one end of the front cover out of the upper plate 2.

[0028] One end of the elastic traction belt 17 is connected to a winding reel 21 via a thread. One end of the winding reel 21 is connected to the electrical mounting plate 2 via a bearing. One end of the winding reel 21 is connected to an external stud 22 via a bearing. Torsional contact blocks 23 are provided on both sides of the electrical mounting plate 2. The external stud 22 cooperates with the torsional contact block 23. When the torsional contact block 23 is pressed, the lower thread of the torsional contact block 23 engages with the external stud 22, causing the external stud 22 to rotate, thereby causing the winding reel 21 to rotate. The elastic traction belt 17 rotates and winds around the winding reel 21, thereby realizing the displacement of the elastic traction belt 17.

[0029] The rear fixed shell 1 and the electrical mounting plate 2 are provided with grooves on all four sides, and the two grooves are connected in a matching manner.
