Description

Technical Field

[0001] The utility model relates to the technical field of DC energy storage capacitors, and more specifically, it relates to a dust-proof device for DC energy storage capacitors. Background Technique

[0002] In the existing technology, the design of the dust-proof mechanism often has the problem of insufficient air permeability. This design defect will cause the heat generated during the operation of the capacitor to be unable to be effectively dissipated, which may then cause overheating, affecting the performance and lifespan of the capacitor. In addition, overheating may also lead to safety problems, especially in high-power application scenarios;

[0003] The dust-proof devices in the existing technology are also inconvenient in terms of installation and disassembly. Many dust-proof devices need to be fixed using screws, nuts or other fasteners. This installation method is not only time-consuming and laborious, but also easily damaged during frequent disassembly and assembly, resulting in a decline in the dust-proof effect. At the same time, due to the large number and variety of fasteners, it is easy to miss or make mistakes during the assembly process, which undoubtedly increases the complexity of the assembly and the potential failure risk. Similarly, during the disassembly process, due to the lack of a design for quick unlocking and disassembly, operators often need to use tools to remove the fasteners one by one to remove the dust-proof device from the capacitor. This is not only time-consuming, but also easily damages the outer shell or internal components during the disassembly process, especially when it is necessary to quickly replace in an emergency, this disassembly method is particularly inconvenient.

By arranging multiple groups of breathable nets 3 on the outer wall of the dust-proof shell 2, the air permeability of the dust-proof shell can be effectively improved, and at the same time, dust can be prevented from entering the capacitor interior.

[0031] Multiple groups of clamping blocks 9 are arranged in the clamping sleeve 8, and the pressing rod 10 is arranged on multiple groups of clamping blocks 9 and is slidably connected to the clamping sleeve 8.

[0032] Push springs 13 are provided on multiple groups of pressing rods 10, and both ends of multiple groups of push springs 13 are respectively connected to the clamping block 9 and the clamping sleeve 8.

[0034] A limiting strip 14 is provided on the clamping sleeve 8, and a limiting groove 15 is opened on the clamping rod 6. The limiting groove 15 is adapted to the limiting strip 14. By arranging the limiting strip 14 on the clamping sleeve 8 and opening the limiting groove 15 on the clamping rod 6, the limiting strip 14 can be adapted to the limiting groove 15, thereby realizing precise position control of the clamping rod 6.

[0035] In this embodiment, when the dust-proof shell 2 needs to be installed, first place the DC energy storage capacitor in the dust-proof shell 2, then cover the top cover 1 on the dust-proof shell 2, and at the same time squeeze the sealing strip 4 so that there is no gap between the dust-proof shell 2 and the top cover 1. At the same time, pass the clamping rod 6 through the mounting hole 5. Then align the limiting strip 14 provided on the clamping sleeve 8 with the limiting groove 15 provided on the clamping rod 6, and then sleeved the clamping sleeve 8 on the clamping rod 6. At this time, the multiple clamping blocks 9 drive the pressure rod 10 to slide outwards along the clamping sleeve 8 through the contraction of the push spring 13, driving the multiple clamping blocks 9 to fit on the inner wall of the clamping sleeve 8 to make way for the clamping rod 6. When the clamping groove 7 moves to the position of the multiple clamping blocks 9, the multiple compression springs 12 contract to pull the multiple pressure plates 11 downwards, and the bottom surfaces of the multiple pressure plates 11 press down on the tops of the multiple pressure rods 10, so that the multiple pressure rods 10 slide along the clamping sleeve 8 to push the multiple clamping blocks 9 to be stuck in the clamping groove 7, and the clamping rod 6 can be clamped and fixed, and the quick clamping installation of the dust-proof shell 2 is completed.

[0036] Please refer to Figure 5 , as an implementation manner of the unlocking mechanism: an unlocking mechanism is provided on the clamping sleeve 8, and the unlocking mechanism includes an unlocking sleeve 16, a control sleeve 17, a tension spring 18 and a lifting handle 19. The unlocking sleeve 16 is slidably installed on the unlocking sleeve 16, the control sleeve 17 is installed on the outer wall of the unlocking sleeve 16, multiple tension springs 18 are provided and the two ends are respectively connected to the clamping sleeve 8 and the control sleeve 17, and multiple lifting handles 19 are installed on the outer wall of the control sleeve 17.

[0037] Sliders 20 are provided inside the unlocking sleeve 16, and multiple sliders 20 are provided. Sliding grooves 21 are formed on the clamping sleeve 8, and multiple sliding grooves 21 are provided and are slidably connected to the multiple sliders 20.

[0038] More specifically, when disassembly is required, pull the lifting handle 19 upwards to drive the control sleeve 17 to move, drive the unlocking sleeve 16 to move through the control sleeve 17, and the unlocking sleeve 16 slides along the sliding groove 21 through the multiple sliders 20 provided on the inner wall. While sliding, push the inner sides of the multiple pressure plates 11, so that one end of the contraction spring 12 rises, so that the multiple pressure plates 11 release the downward pressure on the multiple pressure rods 10. At this time, the multiple clamping blocks 9 are pulled by the contraction of the push spring 13 to disengage from the clamping groove 7, and then the clamping rod 6 can be pulled out of the clamping sleeve 8 to disassemble the dust-proof shell 2.

[0039] In summary, when the overall device is in use or operation: when it is necessary to install the dust-proof housing 2, first place the DC energy storage capacitor in the dust-proof housing 2, then cover the top cover 1 on the dust-proof housing 2, and at the same time squeeze the sealing strip 4 so that there is no gap between the dust-proof housing 2 and the top cover 1. At the same time, pass the clamping rod 6 through the mounting hole 5. Then align the limiting strip 14 provided on the clamping sleeve 8 with the limiting groove 15 provided on the clamping rod 6, and then sleeved the clamping sleeve 8 on the clamping rod 6. At this time, the multiple clamping blocks 9 drive the pressure rod 10 to slide outwards along the clamping sleeve 8 through the contraction of the push spring 13, driving the multiple clamping blocks 9 to fit on the inner wall of the clamping sleeve 8 to make way for the clamping rod 6. When the clamping groove 7 moves to the position of the multiple clamping blocks 9, the multiple compression springs 12 contract to pull the multiple pressure plates 11 downwards, and the bottom surfaces of the multiple pressure plates 11 press down on the tops of the multiple pressure rods 10, so that the multiple pressure rods 10 slide along the clamping sleeve 8 to push the multiple clamping blocks 9 to be stuck in the clamping groove 7, and then the clamping rod 6 can be clamped and fixed, completing the quick clamping installation of the dust-proof housing 2.

[0040] When disassembly is required, pull the lifting handle 19 upwards to drive the control sleeve 17 to move, drive the unlocking sleeve 16 to move through the control sleeve 17. The unlocking sleeve 16 slides along the sliding groove 21 through the multiple sliding blocks 20 provided on the inner wall. While sliding, it pushes the inner sides of the multiple pressure plates 11, causing one end of the contraction spring 12 to rise, so that the multiple pressure plates 11 release the downward pressure on the multiple pressure rods 10. At this time, the multiple clamping blocks 9 are pulled away from the clamping groove 7 through the contraction of the push spring 13, and then the clamping rod 6 can be pulled out of the clamping sleeve 8 to disassemble the dust-proof housing 2.

[0041] In all the above-mentioned solutions, for the connection between two components, welding, the cooperation connection of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered.
