Abstract
Description
Technical Field
[0001] This utility model relates to the field of frequency converter technology, and in particular to an adaptive energy-saving frequency converter. Background Technology
[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to change the frequency of the power supply to control an AC motor. It provides the required power voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. It is currently widely used in motor equipment in various industries.
[0003] For example, the authorized announcement number "CN216599384U" describes a high-efficiency and energy-saving frequency converter. The storage cavity can store the tools used for repairing the frequency converter. When the frequency converter needs to be repaired, the staff does not need to prepare repair tools. They can directly go to the front of the frequency converter, open the closing plate, and select the necessary tools from the storage cavity to carry out the repair work. By setting a moisture-absorbing layer and a thin rubber layer, the outer side of the main body is prevented from being oxidized by air or corroded by moisture.
[0004] The above-mentioned and existing technologies have the following defects: the closing plate of the frequency converter is not equipped with a locking device, and non-professionals can open the closing plate and use the tools used to repair the frequency converter, which will cause damage to the frequency converter; the moisture-absorbing layer is easy to accumulate a lot of dust after long-term use, which will lead to poor heat dissipation effect of the heat dissipation holes. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adaptive and energy-saving frequency converter.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design an adaptive energy-saving frequency converter, including a frequency converter body. The surface of the frequency converter body has a storage slot. Two receiving plates are slidably connected to the inner walls of both sides of the storage slot. A cover plate is hinged to the inner wall of the storage slot. The front surface of the frequency converter body has two insertion slots. The rear surface of the cover plate has two insertion blocks that extend into the insertion slots. A fixing device is provided between the insertion blocks and the insertion slots. The lower surface of the frequency converter body has two studs, each with a triangular block at its lower end, threadedly connected. The lower surfaces of the two insertion blocks have snap-fit grooves. The upper ends of the two studs each have snap-fit blocks that extend into the snap-fit grooves. The front surface of the frequency converter body has an installation slot. The front surface of the frequency converter body has a U-shaped baffle. A closing plate covering the installation slot is slidably connected to the U-shaped baffle. The surface of the closing plate has multiple heat dissipation holes. The rear surface of the closing plate has a moisture-absorbing layer. A limiting device is provided on the side of the closing plate.
[0008] Preferably, the fixing device includes a limiting groove, a return spring is provided on the lower inner wall of the limiting groove, a connecting plate is provided on the upper end of the return spring, a support column is provided on the upper surface of the connecting plate, a rotating shaft is rotatably connected to the support column, hemispheres are fixedly connected to both ends of the rotating shaft, and an arc-shaped groove matching the hemisphere is opened on the upper inner wall of the insertion groove.
[0009] Preferably, the limiting device includes a Z-shaped block, which is threadedly connected to the inverter body via multiple connecting bolts.
[0010] Preferably, the Z-shaped block has dustproof blocks at both the top and bottom ends.
[0011] Preferably, the upper end of the receiving plate is provided with two anti-fall edges.
[0012] Preferably, the diameter of the snap-fit block is larger than the through hole through the lower surface of the inverter body.
[0013] The adaptive energy-saving frequency converter proposed in this utility model has the following advantages: Through the fixed device, maintenance tools are placed inside the receiving plate, and then the cover is closed. The elasticity of the return spring causes the hemispherical block to engage with the arc-shaped groove. Then, a special triangular key is used to rotate the triangular block, causing the locking block to engage within the locking groove. The fixed device prevents non-professionals from opening the cover, thus preventing the use of tools for frequency converter maintenance and avoiding damage to the frequency converter. The limit device also prevents the moisture-absorbing layer from accumulating dust over time. By unscrewing the connecting bolt and pulling the closed plate, the moisture-absorbing layer can be cleaned or replaced, preventing poor heat dissipation through the heat dissipation holes.
