Description

Technical Field

[0001] This utility model relates to the field of power transfer devices, and more specifically to a power transfer device. Background Technology

[0002] With the continuous development and expansion of the power system, the requirements for power supply reliability are also increasing. The traditional single power supply method can no longer meet the continuous operation needs of critical equipment and systems. Therefore, power transfer devices have emerged. By reliably switching between two power sources, power transfer devices can reduce the downtime of equipment due to power interruption and improve the overall reliability and availability of the system.

[0003] The existing power transfer devices have certain design flaws, which make the entire switching process not as stable and reliable as expected. This unstable switching state undoubtedly brings great risks of power outages. Even a momentary error or malfunction during the switching process is very likely to cause power supply interruption, causing serious interference and damage to the normal operation of related equipment and systems.

[0004] Furthermore, in daily use environments, there are a large number of dust particles in the air. These dust particles will gradually adhere to the external surface of the power transfer device as well as some gaps and corners inside. When the dust accumulates to a certain extent, it can easily cause a short circuit.

[0005] To address the aforementioned problems, this application provides a power switching device. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a power switching device to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a power switching device, including a housing assembly and a dustproof assembly and an installation assembly installed on the housing assembly, a transmission assembly and a connecting assembly installed on the housing assembly, transmission assemblies provided on both sides of the connecting assembly, and a pushing assembly installed between the transmission assembly and the installation assembly;

[0009] Preferably, the dustproof assembly includes a dustproof plate, a first magnetic sheet, a second magnetic sheet, a first hinge, and a second hinge. The dustproof plate is disposed above the housing assembly. The second hinge is fixedly installed above the rear side of the vertical plate and hinged to the first hinge. The end of the first hinge away from the second hinge is fixedly installed on the dustproof plate. Two symmetrical first magnetic sheets are fixedly installed on the lower front side of the dustproof plate. A second magnetic sheet is fixedly installed on the upper part of the fixed plate at a position corresponding to the first magnetic sheet. At this time, the dustproof plate can be pressed down to rotate along the main axis at the hinge point of the first hinge and the second hinge until the first magnetic sheet and the second magnetic sheet are in contact.

[0010] Preferably, the transmission assembly includes a rotary motor, a threaded screw, and a slider. The rotary motor is fixedly mounted on the front side of the fixed plate, and the rotary motor drive shaft is fixedly sleeved with the threaded screw. The threaded screw rotates and sleeves the fixed plate at its connection with the fixed plate. The slider slides and is threadedly engaged with the fixed plate. At this time, the threaded screw rotates along its own axis under the action of the rotary motor. Under the threaded engagement with the slider, the slider and the connecting assembly mounted above it are driven to move forward.

[0011] Preferably, the connecting assembly includes a movable component, an insulating block, and a conductive block, wherein the movable component is fixedly mounted on the transmission assembly, the conductive block is fixedly mounted inside the movable component, and two insulating blocks are disposed on both sides of the conductive block.

[0012] Preferably, the transmission component includes a secondary transmission line, a primary transmission line, a secondary power line, a primary power line, and a transmission detector. The secondary transmission line and the primary transmission line are located on the right side of the connection component, and the secondary power line and the primary power line are located on the left side of the connection component. The rear transmission line of the secondary transmission line is connected to the primary transmission line, and a transmission detector is fixedly installed on the extension line of the connection between the secondary transmission line and the primary transmission line.

[0013] Preferably, the pushing assembly includes a push block, a compression spring, and a slide groove. The fixed plate has a slide groove at the connection with the pushing assembly. The push block is slidably connected to the slide groove. The compression spring is disposed in the slide groove. The upper ends of the four push blocks are respectively fixedly sleeved on the auxiliary transmission line, the main transmission line, the auxiliary power line, and the main power line. At this time, under the action of the compression spring, the slide groove drives the connection ends of the main power line and the main transmission line to fit against both sides of the conductive block.

[0014] Preferably, the mounting assembly includes a mounting plate and fixing screws, wherein the mounting plate is fixedly installed below the fixing plate, and the fixing screws are located at the four corners of the mounting plate and threadedly connected thereto. In this case, the mounting plate is fixedly installed inside the electrical box by rotating the fixing screws.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] When using the device, press down the dustproof plate to make it rotate along the hinge axis until the first magnetic plate and the second magnetic plate are in contact, which can prevent dust from entering the device. When the transmission detector detects unstable data, it sends a signal to control the rotary motor to run, which in turn drives the slider and the connecting components installed on it to move forward through the threaded connection until the auxiliary power line is electrically connected to the auxiliary transmission line through the conductive block. This design makes the power switching more stable. Attached Figure Description
