Description

Technical Field

[0001] This utility model relates to the field of contactless voltage regulator technology, and in particular to a contactless voltage regulator. Background Technology

[0002] Contactless voltage regulators are a new type of power supply voltage regulation device based on power electronics technology and digital control principles. They replace traditional mechanical contacts with power semiconductor devices (such as thyristors and IGBTs) to achieve rapid adjustment and stable output of the input voltage. They overcome the defects of traditional voltage regulators (such as mechanical voltage regulators and magnetic saturation regulators) such as mechanical wear and slow response, and have advantages such as high precision, high reliability, and long lifespan. They are widely used in scenarios with high power supply stability requirements.

[0003] Existing contactless voltage regulators often use built-in fans to dissipate the heat generated during operation. However, this method is not convenient for blocking and protecting the heat dissipation vents from dust. As a result, dust enters the voltage regulator through the vents and accumulates on the circuit boards and power devices over time. This not only affects heat dissipation efficiency, causing the equipment to overheat and degrade in performance or even malfunction, but may also cause short circuits and accelerate the aging and damage of electronic components. Utility Model Content

[0004] The purpose of this invention is to provide a contactless voltage regulator to solve the problem that existing contactless voltage regulators are inconvenient to block and protect against dust at the heat dissipation vents.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a contactless voltage regulator, including a contactless voltage regulator body;

[0006] The outer wall of the contactless voltage regulator body is equipped with a dustproof mechanism.

[0007] The dustproof mechanism includes a dustproof cover plate fixedly installed on one side of the contactless voltage regulator body. A docking plate is fixedly connected to the inner wall of the dustproof cover plate. A positioning slot is opened inside the docking plate. A dustproof net is installed on the inner wall of the dustproof cover plate. An avoidance groove is opened inside the dustproof net. A movable groove is opened on the inner side wall of the avoidance groove. A guide groove is opened on the inner bottom wall of the movable groove. A spring block is movably connected inside the movable groove. A guide slider is fixedly connected to the bottom of the spring block.

[0008] Preferably, the docking plate forms a sliding structure with the dustproof net through the avoidance groove, and the docking plate is symmetrically arranged with respect to the central axis of the dustproof cover, so that the dustproof net can be slidably inserted along the docking plate.

[0009] Preferably, the docking plate is engaged with the spring block through a positioning slot, and one end of the spring block is hemispherical, which allows one end of the spring block to be engaged in the positioning slot for limiting.

[0010] Preferably, the dustproof net forms a sliding structure with the spring block through the movable groove, and the dustproof net forms a sliding structure with the guide slider through the guide groove, so that the spring block can slide along the movable groove and be retracted into the dustproof net.

[0011] Preferably, a cleaning mechanism is installed inside the dust cover. The cleaning mechanism includes a guide rod fixedly installed on the inner wall of the dust cover. A cleaning brush is movably connected inside the guide rod. A handle is fixedly connected to the bottom of the cleaning brush. A first magnetic block is embedded inside the cleaning brush. The cleaning mechanism also includes a second magnetic block fixedly installed inside the dust cover.

[0012] Preferably, the guide rod is symmetrically arranged about the central axis of the cleaning brush, and the guide rod and the cleaning brush form a sliding structure, which allows the cleaning brush to slide stably along the guide rod.

[0013] Preferably, the cleaning brush and the dustproof net form a sliding structure, and the first magnetic block and the second magnetic block are magnetically connected, so that the cleaning brush can slide along the first magnetic block and clean the dust attached to the outer wall of the first magnetic block.

[0014] The contactless voltage regulator provided by this utility model has the following advantages:

[0015] The dustproof mechanism allows the moving dustproof net to slide along the docking plate and be inserted into it. This causes the docking plate to press against the spring block, pulling the spring block into the dustproof net. When the docking plate is fully inserted into the clearance groove, the spring block can be reset and one end can be inserted into the positioning slot for limiting. This allows the dustproof net to be installed inside the dustproof cover, effectively protecting the heat dissipation vents of the contactless voltage regulator body from dust accumulation, thus preventing dust buildup on the circuit boards inside the contactless voltage regulator body from affecting heat dissipation and operating efficiency.

[0016] Furthermore, the combined action of the guide slider and the guide groove can improve the stability of the spring block's sliding motion, thereby further enhancing the stability of the dustproof net's limiting installation.

[0017] With the dust cover and cleaning mechanism in place, the cleaning brush can be moved steadily along the guide rod by pulling the handle, which in turn moves the cleaning brush along the dust net, making it easier to clean the dust adhering to the outer wall of the dust net.

[0018] Furthermore, the cleaning brush can be positioned when not in use due to the magnetic attraction of the first and second magnetic blocks.

[0019] Furthermore, because the bottom of the dust cover is designed with a slot, the dust after the dust net is cleaned can be discharged through the slot at the bottom of the dust cover. Attached Figure Description

One end of the spring block 28 is hemispherical. The dustproof net 24 forms a sliding structure with the spring block 28 through the movable groove 26. The dustproof net 24 forms a sliding structure with the guide slider 29 through the guide groove 27.

[0030] By moving the dustproof net 24, the clearance groove 25 is aligned with the docking plate 22, causing the dustproof net 24 to slide along the docking plate 22 and be inserted into it. The docking plate 22 then presses against the spring block 28, causing the spring block 28 to slide along the movable groove 26 and be retracted into the dustproof net 24. The guide slider 29 slides along the guide groove 27. When the docking plate 22 is fully inserted into the clearance groove 25, the spring block 28 can be reset under the action of the spring, and one end of it can be inserted into the positioning groove 23 for limiting, so that the dustproof net 24 is installed inside the dustproof cover plate 21.

[0032] By pulling the handle 33, the first magnetic block 34 and the second magnetic block 35 connected by magnetic attraction can be separated under the action of external force, so that the cleaning brush 32 can slide stably along the guide rod 31. When the cleaning brush 32 slides along the outer wall of the dustproof net 24, the dust attached to the outer wall of the dustproof net 24 can be cleaned, and the dust can be discharged through the slot at the bottom of the dustproof cover plate 21.
