Description

Technical Field

[0001] This invention relates to the field of diode technology, specifically to a high-power anti-reverse diode for new energy applications. Background Technology

[0002] Diodes are among the most commonly used electronic components. One function of reverse-charging diodes is to prevent the current from the battery from flowing back to the solar panel or array when it is not generating electricity. This not only wastes energy but also causes the panel or array to overheat or even be damaged. Reverse-charging diodes can be fixed to charging piles. However, in using a high-power reverse-charging diode for new energy applications, it was found that it could not effectively dissipate heat from the inside of the insulating casing, easily affecting the lifespan of the components inside; the casing and cover were not effectively sealed, making it easy for water to enter; and the diode was inconvenient to install and remove, making it inconvenient to use. This paper proposes an improvement to a high-power reverse-charging diode for new energy applications to address these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a high-power anti-reverse diode for new energy applications, in order to solve the problem mentioned in the background art that the internal components of the insulating housing cannot be effectively cooled, which easily affects their service life.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-power anti-reverse diode for new energy applications, comprising a base, an insulating shell fixedly connected to the top of the base, a cover plate provided at the top of the insulating shell, electrode connection screws provided on both sides inside the insulating shell, a heat dissipation groove provided at the bottom of the insulating shell, a baffle provided inside the heat dissipation groove, a second heat dissipation hole provided inside the baffle, a fixing block fixedly connected to both sides at the bottom of the baffle, a hinge block provided on both sides at the bottom of the base, a movable block movably hinged to the outside of the hinge block, a groove provided on one side of the fixing block, a protrusion fixedly connected to the other side of the movable block, a cavity provided inside the base, and a first heat dissipation hole provided at both ends of the cavity.

[0005] Preferably, the baffle is installed inside the heat dissipation slot, and the second heat dissipation hole and the first heat dissipation hole are the same size.

[0006] Preferably, the protrusion is embedded inside the groove, and the protrusion and the groove cooperate with each other.

[0007] Preferably, the second heat dissipation holes are arranged at equal intervals inside the baffle, and the first heat dissipation holes are arranged at equal intervals on both sides of the base.

[0008] Preferably, a fixing sleeve is provided on the outside of the connection between the insulating shell and the cover plate. A spring groove is fixedly connected to the inner side wall of the fixing sleeve. A connecting column is movably connected inside the spring groove. A limit spring is fixedly connected to one end of the connecting column, and a limit plate is fixedly connected to the other end of the connecting column. A sealing gasket is fixedly connected to one end of the limit plate. The sealing gasket is provided at both ends and both sides of the cover plate.

[0009] Preferably, the limiting spring is fixedly connected between the connecting post and the inside of the spring groove, and the connecting post slides inside the spring groove.

[0010] Preferably, the outer surface of the insulating shell is coated with a zinc layer, and mounting holes are respectively provided at the four corners inside the base. Fixing bolts are provided inside the mounting holes, and rubber pads are provided at the top of the fixing bolts.

[0011] Preferably, the mounting holes are provided in four sets, and the mounting holes are symmetrically distributed about the vertical center line of the base.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the high-power new energy anti-reverse diode not only facilitates heat dissipation inside the insulating shell and prevents water from entering the shell, but also facilitates the installation of the diode;

[0013] (1) By providing a first heat dissipation hole, a heat dissipation groove, a second heat dissipation hole, a protrusion, a fixed block, a groove, a hinge block, and a movable block, the baffle installed inside the heat dissipation groove can prevent dust and impurities from entering the interior of the insulating shell. The second heat dissipation hole opened inside the baffle can facilitate heat dissipation from the interior of the insulating shell. When the interior temperature of the insulating shell is high, the temperature can be discharged from the interior of the insulating shell through the second heat dissipation hole and the first heat dissipation hole, thereby cooling the interior of the insulating shell. Cooling the interior of the insulating shell can prevent the high interior temperature of the insulating shell from affecting the service life of the internal components of the insulating shell. When the baffle needs to be disassembled, the movable block can be rotated to disengage the protrusion from the interior of the groove.

[0014] (2) By setting a fixed sleeve, connecting column, spring groove, limiting plate, sealing gasket and limiting spring, after the cover plate is installed on the top of the insulating shell, the fixed sleeve is put on the outside of the connection between the insulating shell and the cover plate. After the fixed sleeve is put on, the limiting spring inside the spring groove will use its own elasticity to make the connecting column drive the limiting plate and the sealing gasket to adhere to the connection between the insulating shell and the cover plate, thereby sealing the connection to prevent water from entering the interior of the insulating shell and damaging the components inside the insulating shell. The spring groove can limit the limiting spring to prevent the limiting spring from driving the limiting plate and the sealing gasket to shake.

[0015] (3) A zinc layer is plated on the surface of the insulating shell by setting a fixing bolt, mounting hole, zinc layer and rubber pad. The zinc layer protects the insulating shell and also provides double insulation. When the anti-light diode needs to be installed, the mounting hole inside the base is aligned with the mounting hole at the installation location. After aligning the mounting hole, the fixing bolt is screwed into the mounting hole to fix the base, thus completing the installation of the anti-light diode. A rubber pad is set at the top of the fixing bolt to prevent the fixing bolt from getting stuck inside the mounting hole. Attached Figure Description

[0023] 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.

[0024] Example 1: Please refer to Figure 1-6A high-power anti-reverse diode for new energy includes a base 1, an insulating shell 2 fixedly connected to the top of the base 1, a cover plate 4 provided at the top of the insulating shell 2, electrode connection screws 5 provided on both sides inside the insulating shell 2, a heat dissipation groove 12 provided at the bottom of the insulating shell 2, a baffle 13 provided inside the heat dissipation groove 12, a second heat dissipation hole 14 provided inside the baffle 13, a fixing block 20 fixedly connected to both sides at the bottom of the baffle 13, a hinge block 22 provided on both sides at the bottom of the base 1, a movable block 23 movably hinged to the outside of the hinge block 22, a groove 21 provided on one side of the fixing block 20, a protrusion 19 fixedly connected to the other side of the movable block 23, a cavity 10 provided inside the base 1, and a first heat dissipation hole 9 provided at both ends of the cavity 10.

[0025] The baffle 13 is installed inside the heat dissipation slot 12. The second heat dissipation hole 14 is the same size as the first heat dissipation hole 9. The protrusion 19 is embedded in the groove 21. The protrusion 19 and the groove 21 cooperate with each other. The second heat dissipation hole 14 is arranged at equal intervals inside the baffle 13. The first heat dissipation hole 9 is arranged at equal intervals on both sides of the base 1.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the baffle 13 installed inside the heat dissipation groove 12 can prevent dust and impurities from entering the interior of the insulating shell 2. The second heat dissipation hole 14 opened inside the baffle 13 can facilitate heat dissipation from the interior of the insulating shell 2. When the interior temperature of the insulating shell 2 is high, the temperature can be discharged from the interior of the insulating shell 2 through the second heat dissipation hole 14 and the first heat dissipation hole 9, thereby cooling the interior of the insulating shell 2. Cooling the interior of the insulating shell 2 can prevent the high interior temperature of the insulating shell 2 from affecting the service life of the internal components of the insulating shell 2. When it is necessary to disassemble the baffle 13, simply rotate the movable block 23 to disengage the protrusion 19 from the interior of the groove 21.

[0027] Example 2: A fixing sleeve 3 is provided on the outside of the connection between the insulating shell 2 and the cover plate 4. A spring groove 15 is fixedly connected to the inner side wall of the fixing sleeve 3. A connecting post 6 is movably connected inside the spring groove 15. A limit spring 18 is fixedly connected to one end of the connecting post 6, and a limit plate 16 is fixedly connected to the other end of the connecting post 6. A sealing gasket 17 is fixedly connected to one end of the limit plate 16. The sealing gasket 17 is provided at both ends and both sides of the cover plate 4. The limit spring 18 is fixedly connected between the connecting post 6 and the inside of the spring groove 15. The connecting post 6 slides inside the spring groove 15.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, after the cover plate 4 is installed on the top of the insulating housing 2, the fixing sleeve 3 is put on the outside of the connection between the insulating housing 2 and the cover plate 4. After the fixing sleeve 3 is put on, the limiting spring 18 inside the spring groove 15 will use its own elasticity to make the connecting column 6 drive the limiting plate 16 and the sealing gasket 17 to adhere to the connection between the insulating housing 2 and the cover plate 4, thereby sealing the connection to prevent water from entering the interior of the insulating housing 2 and damaging the components inside the insulating housing 2.

[0029] Example 3: The outer surface of the insulating shell 2 is coated with a zinc layer 11. The four corners inside the base 1 are respectively provided with mounting holes 8. The mounting holes 8 are provided with fixing bolts 7. The top of the fixing bolts 7 is provided with rubber pads 24. There are four sets of mounting holes 8. The mounting holes 8 are symmetrically distributed about the vertical center line of the base 1.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, a zinc layer 11 is plated on the surface of the insulating shell 2. The zinc layer 11 protects the insulating shell 2 and provides double insulation. When installing the light-shielding diode, align the mounting hole 8 inside the base 1 with the mounting hole 8 at the installation location. After aligning the mounting hole 8, screw the fixing bolt 7 into the mounting hole 8 to fix the base 1, thus completing the installation of the light-shielding diode. A rubber pad 24 is provided at the top of the fixing bolt 7 to prevent the fixing bolt 7 from getting stuck inside the mounting hole 8.

[0031] Working Principle: When using this invention, align the mounting hole 8 inside the base 1 with the mounting hole 8 at the installation location when installing the light-shielding diode. After aligning the mounting hole 8, screw the fixing bolt 7 into the mounting hole 8 to fix the base 1, thus completing the installation of the light-shielding diode. A rubber pad 24 is provided at the top of the fixing bolt 7 to prevent the fixing bolt 7 from getting stuck inside the mounting hole 8. A zinc layer 11 is plated on the surface of the insulating shell 2, which protects the insulating shell 2 and provides double insulation. To remove the light-shielding diode, simply unscrew the fixing bolt 7 out of the mounting hole 8. Install the cover plate 4 onto the top of the insulating shell 2. After installing the cover plate 4, put the fixing sleeve 3 on the outside of the connection between the insulating shell 2 and the cover plate 4. The limiting spring 18 inside the rear spring groove 15 will, through its own elasticity, cause the connecting post 6 to drive the limiting plate 16 and the sealing gasket 17 to adhere to the connection between the insulating housing 2 and the cover plate 4, thereby sealing the connection and preventing water from entering the interior of the insulating housing 2 and damaging the internal components. The second heat dissipation hole 14 inside the baffle 13 can facilitate heat dissipation from the interior of the insulating housing 2. When the internal temperature of the insulating housing 2 is high, the heat can be discharged from the interior of the insulating housing 2 through the second heat dissipation hole 14 and the first heat dissipation hole 9, thereby cooling the interior of the insulating housing 2. Cooling the interior of the insulating housing 2 can prevent the high internal temperature from affecting the service life of the internal components. When the baffle 13 needs to be disassembled, simply rotate the movable block 23 to disengage the protrusion 19 from the interior of the groove 21.
