Description

Technical Field

[0001] This utility model relates to the field of ballast technology, and in particular to an explosion-proof electronic ballast. Background Technology

[0002] Electronic ballasts require cooling devices during operation because they generate heat. If this heat cannot be dissipated in time, the ballast temperature may rise. When the temperature rises to a certain level, the performance of the internal insulation material of the ballast deteriorates, increasing the risk of electrical faults such as short circuits and leakage. Sparks generated by these faults can easily become ignition sources for surrounding explosive gases or dust, leading to explosions. Furthermore, high temperatures can accelerate the aging and damage of the ballast's electronic components, further affecting its normal operation and even causing dangerous situations such as high-temperature arcing. Installing cooling devices effectively reduces the ballast temperature, keeping it within a safe operating range. This reduces the likelihood of electrical faults and insulation damage caused by overheating, thereby lowering the risk of ignition sources such as sparks. It improves the safety and reliability of the ballast in potentially explosive environments, preventing explosions caused by ballast overheating and ensuring the safety of the entire electrical system and the surrounding environment.

[0003] In the prior art, Chinese Patent No. CN 219204729 U discloses an explosion-proof electronic ballast, including an electronic ballast body. The electronic ballast body includes an explosion-proof shell and an electronic ballast circuit board. A support assembly is installed on the electronic ballast circuit board. The support assembly includes an aluminum plate and a pillar. A heat dissipation assembly is installed inside the explosion-proof shell. The heat dissipation assembly includes silicone grease and a fan. A fan and a filter are installed inside the fan. A temperature control assembly is installed at the bottom of the electronic ballast circuit board. This explosion-proof electronic ballast can dissipate the heat generated during operation in a timely manner, avoiding damage to the electrical components or even explosion caused by the high temperature of the electronic ballast circuit board, thus ensuring the safe operation of the electronic ballast.

[0004] In this patent, the fan is located inside the electronic ballast body. The fan may be damaged after long-term operation, thus requiring maintenance and replacement. However, since the fan is installed inside the electronic ballast body in this patent, there is a problem of inconvenience in disassembly and maintenance. Utility Model Content

[0005] In view of the technical problem mentioned in the background art, where the fan is installed inside the electronic ballast body, which makes disassembly and maintenance inconvenient, this utility model provides an explosion-proof electronic ballast.

[0006] The technical solution adopted by this utility model is: an explosion-proof electronic ballast, including a ballast body, an air inlet on the top of the ballast body, an air outlet on the outside of the ballast body, a mounting bracket on the top of the ballast body, multiple sets of fans fixedly connected to the top of the mounting bracket, multiple sets of arc-shaped rings fixedly connected to the outside of the mounting bracket, and a snap-fit ​​assembly that snaps into the arc-shaped rings on the top of the ballast body.

[0007] In one embodiment, the snap-fit ​​assembly consists of multiple sets of rotating rods rotatably connected to the top of the ballast body, with multiple sets of locking strips fixedly connected to the outside of the rotating rods, and an arc-shaped groove provided inside the arc-shaped ring.

[0008] In one embodiment, a limiting plate is also included, with limiting rods fixedly connected to both sides of the bottom of the limiting plate, and a positioning groove is provided at the top of the rotating rod.

[0009] In one embodiment, a plurality of arc-shaped spring plates are fixedly connected to the top of the ballast body, and the arc-shaped spring plates are snapped into the top of the limiting plate.

[0010] In one embodiment, magnets are evenly and fixedly connected to the bottom of the limiting rod and the inner bottom of the positioning groove.

[0011] In one embodiment, the limiting rod and the limiting groove are polygonal structures.

[0012] In one embodiment, the limiting rod is covered with an anti-slip sleeve.

[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, in this utility model, the mounting bracket is placed on the ballast body and the fan is aligned with the air inlet. Then, by operating the snap-fit ​​component, the snap-fit ​​component is snapped into the arc ring, thereby achieving the initial installation of the mounting bracket and the fan, which is convenient for disassembly and assembly, and convenient for maintenance and replacement. Finally, the fan blows air into the ballast body through the air inlet for heat dissipation, thus avoiding the ballast body from exploding due to high temperature. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described below.

[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: an explosion-proof electronic ballast, including a ballast body 1, an air inlet 13 on the top of the ballast body 1, an air outlet 2 on the outside of the ballast body 1, a mounting bracket 3 on the top of the ballast body 1, and multiple sets of fans 4 fixedly connected to the top of the mounting bracket.

[0026] In a further design, multiple sets of arc-shaped rings 6 are fixedly connected to the outside of the mounting bracket 3. The arc-shaped rings 6 are provided with arc-shaped grooves 7. The top of the ballast body 1 is provided with a snap-fit ​​component that snaps into the arc-shaped rings 6.

[0027] In this embodiment, the mounting bracket 3 is placed on the ballast body 1, with the fan 4 aligned with the air inlet 13. Then, by operating the snap-fit ​​assembly, the assembly engages with the arc-shaped ring 6, thus achieving initial installation of the mounting bracket 3 and fan 4. This facilitates disassembly and assembly, and allows for easy maintenance and replacement. Finally, air is blown by the fan 4 through the air inlet 13 to dissipate heat inside the ballast body 1, preventing the ballast body 1 from exploding due to high temperatures.

[0028] Specifically, the snap-fit ​​assembly consists of multiple sets of rotating rods 8 rotatably connected to the top of the ballast body 1. Multiple sets of snap-fit ​​strips 12 are fixedly connected to the outside of the rotating rods 8, and a limiting plate 9 is also included. Limiting rods 10 are fixedly connected to both sides of the bottom of the limiting plate 9. The top of the rotating rods 8 is provided with a positioning groove 11. When the rotating rods 8 are rotated, the rotating rods 8 drive the snap-fit ​​strips 12 to rotate, so that the snap-fit ​​strips 12 are snapped into the arc groove 7 of the arc ring 6, thereby realizing the initial installation of the mounting bracket 3 and the fan 4.

[0029] In a further design, multiple sets of arc-shaped spring plates 5 are fixedly connected to the top of the ballast body 1. The arc-shaped spring plates 5 are snapped onto the top of the limiting plate 9. The arc-shaped spring plates 5 are designed to abut against and snap onto the top of the limiting plate 9, ensuring the stability of the limiting plate 9.

[0030] To ensure a secure connection between the limiting rod 10 and the positioning groove 11, magnets are evenly distributed and fixedly connected to the bottom of the limiting rod 10 and the inner bottom of the positioning groove 11. The limiting rod 10 and the positioning groove have a polygonal structure, and an anti-slip sleeve is fitted on the outside of the limiting rod 10.

[0031] The usage process of this utility model is as follows:

[0032] Place the mounting bracket 3 on the ballast body 1 and align the fan 4 with the air inlet 13. Then rotate the rotating rod 8, which drives the retaining strip 12 to rotate, so that the retaining strip 12 engages with the arc groove 7 of the arc ring 6, thereby achieving the initial installation of the mounting bracket 3 and the fan 4.

[0033] Then, take the limiting plate 9, insert the limiting rod 10 into the positioning groove 11, and lock the position of the rotating rod 8 to complete the installation of the fan 4.

[0034] Finally, the air is blown by the fan 4 and enters the ballast body 1 through the air inlet 13 for heat dissipation, thus avoiding the ballast body 1 from exploding due to high temperature;

[0035] When it is necessary to disassemble the mounting bracket 3, simply remove the limiting rod 10 and the limiting plate 9, then rotate the rotating rod 8 to prevent the locking strip 12 from engaging with the arc groove 7, and then remove the mounting bracket 3.

[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
