Description

Technical Field

[0001] This utility model relates to the field of DC power supply technology, specifically a digital wall-mounted DC power supply. Background Technology

[0002] A DC power supply system is a device that converts alternating current (AC) to direct current (DC). It is widely used in communications, power, industrial control, aerospace, and other fields. Its main task is to provide power for relay protection devices, circuit breaker operation, and various signal circuits, ensuring the safe operation of the power system. DC power supply systems are unaffected by generators, plant power supplies, or system operating modes. Even in the event of an external AC power outage, DC power can continue to be provided by a backup power source—a battery.

[0003] Existing digital wall-mounted DC power supplies are generally large in size and heavy in weight, making them difficult to move and transport. Moreover, existing digital wall-mounted DC power supplies are usually supported by feet when placed on the ground, resulting in a small contact area, insufficient stability, and a tendency to slide. Utility Model Content

[0004] The purpose of this utility model is to provide a digital wall-mounted DC power supply. When the cabinet needs to be moved, the electric hydraulic rod can be activated to push the casters out of the bottom cylinder, so that the cabinet can be moved directly. At the same time, the transport personnel can use the handle to assist in the transport and briefly lift the cabinet, which improves the convenience of transporting the digital wall-mounted DC power supply. After the digital wall-mounted DC power supply is placed, the buffer pad has a large contact area with the ground, which improves the stability and anti-slip properties of the cabinet.

[0005] To achieve the above objectives, a digital wall-mounted DC power supply is provided, comprising: a cabinet, wherein a buffer pad and a bottom frame are fixedly connected to the bottom of the cabinet, the buffer pad being located inside the bottom frame; bottom heat dissipation holes are provided on the four side walls of the bottom frame, the number of bottom heat dissipation holes being provided and evenly distributed on the bottom frame; lifting components are provided at the bottom of the cabinet, the number of lifting components being provided and evenly distributed at the four corners of the bottom of the cabinet, the lifting components being located between the bottom frame and the buffer pad; handles are fixedly connected to the left and right side walls of the cabinet, the cross-section of the handles being arc-shaped, the number of handles being provided and symmetrically distributed on the cabinet; a front door is provided on the front side wall of the cabinet, and a glass window and a lock are fixedly connected to the front door.

[0006] According to the aforementioned digital wall-mounted DC power supply, the lifting assembly includes a base cylinder, a lower limit ring, an electro-hydraulic rod, a moving block, a connecting rod, and casters.

The connecting rod is fixedly connected to the bottom of the moving block. Casters are fixedly connected to the bottom of the connecting rod. When the electro-hydraulic rod is activated, the casters extend out of the base cylinder, thereby facilitating the movement of the cabinet.

[0007] According to the aforementioned digital wall-mounted DC power supply, the buffer pad is a shock-absorbing rubber pad, and the bottom of the buffer pad is provided with anti-slip texture. This improves the buffering and shock absorption capacity and anti-slip properties.

[0008] According to the aforementioned digital wall-mounted DC power supply, the cabinet is internally equipped with a DC power system, a small storage battery, and a controller. The electro-hydraulic rod is electrically connected to the controller, and the controller is electrically connected to the small storage battery. The extension and retraction of the electro-hydraulic rod can be controlled via the controller.

[0009] According to the aforementioned digital wall-mounted DC power supply, the front door and the cabinet are rotatably connected by hinges and fixed by locks.

[0010] According to the aforementioned digital wall-mounted DC power supply, the cabinet has multiple side ventilation holes evenly distributed on its left and right side walls. These side ventilation holes are used for heat dissipation.

[0011] According to the aforementioned digital wall-mounted DC power supply, the movable block, connecting rod, and caster wheels are all located inside the base cylinder, and the base cylinder is at the same height as the base frame.
