Description

Technical Field

[0001] The utility model belongs to the technical field of direct current power supplies, in particular to a modular explosion-proof direct current power supply. Background Art

[0002] A DC power supply is a device that can maintain a constant voltage and current in a circuit. Through non-static action, a DC power supply moves positive charge from the negative electrode with a lower potential to the positive electrode with a higher potential through the inside of the power supply, thereby maintaining the potential difference between the two electrodes and forming a constant current. It can be used in routers, switches, servers and other equipment in data centers to support redundant parallel applications and improve power supply reliability. However, it still has the following disadvantages in actual use:

[0003] 1. When the DC power supply is working, after the corresponding structure is installed in the appropriate position, it needs to be disassembled, replaced or repaired after the power supply fails or is damaged. During the disassembly, replacement and repair process, a large number of screws and other structures need to be removed, which is not convenient for operation;

[0004] 2. Secondly, when the DC power supply is running, it can only be installed in a suitable position through the corresponding structure. During the operation of the DC power supply, it will generate heat, which will increase the line resistance of the circuit, causing waste of electric energy and affecting the operating efficiency of the DC power supply. A high-power fan is required to dissipate the heat, and the noise is relatively large during heat dissipation. Utility Model Content

[0005] The purpose of the utility model is to provide a modular explosion-proof DC power supply, which solves the problems of inconvenient disassembly and assembly of the DC power supply during operation and large heat dissipation noise during operation of the DC power supply by arranging a bottom mounting plate, a power supply body, a rotating frame and a water cooling plate.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a modular explosion-proof direct current power supply, comprising a bottom mounting plate, a power supply body, a rotating frame and a water cooling plate, wherein L-shaped limiting plates are fixed at two long sides of the top of the bottom mounting plate, the power supply body is arranged on the top of the bottom mounting plate, and sliding bars are fixed at the lower parts of both sides of the power supply body, and the sliding bars are slidably connected at the gap between the L-shaped limiting plate and the bottom mounting plate, a fixed frame is arranged at one end of the power supply body, a rotating frame is arranged at the lower part of the fixed frame, and a water cooling plate is arranged on the top of the power supply body. When working, the power supply body is supported thereon by the bottom mounting plate, and the rotating frame drives the threaded rod to rotate when rotating. When the power supply body works, power is supplied to equipment using direct current, and the power supply body is cooled and lowered when working by the water cooling plate.

[0008] Furthermore, a rear baffle is fixed to the top of the bottom mounting plate away from the short side of the fixed frame, and a wire hole is opened through the rear baffle. When the bottom mounting plate is working, the position of the rear end of the power supply body is limited by the rear baffle, and the position of the power supply line is determined by the wire hole.

[0009] Furthermore, side panels are fixed at the edges of the tops of the straight parts of the two L-shaped limiting plates that are away from each other, and mounting screw holes are provided on the top of the bottom mounting plate at the bottom of the fixed frame. When the L-shaped limiting plate is working, the position of the water cooling plate is limited by supporting the side panels.

[0010] Furthermore, a plurality of power supply wires are fixed to one end of the power supply body away from the fixing frame. The power supply wires pass through the wire holes and extend out. The power supply body supplies power to the device using a DC power supply through the power supply wires.

[0011] Furthermore, a power connection port is fixed to the end of the power supply body in the fixed frame, a power switch is fixed to the end of the power supply body on one side of the power connection port, pulling handles are symmetrically fixed in the fixed frame, and the power connection port and the power switch are arranged between the two pulling handles. The power supply body is connected to the power supply through the power connection port, and the power supply body is driven to move when the pulling handle is pulled.

[0012] Furthermore, a movable hole is opened in the center of the bottom of the fixed frame, and a threaded rod is fixed in the center of the bottom end of the rotating frame. The threaded rod passes through the movable hole and is threadedly connected in the mounting screw hole. The water-cooling plate is jointly fixed on the top of the two side plates, and the water-cooling plate is fixed on one side of the rear baffle. When the fixed frame is working, the threaded rod is movably connected through the movable hole and is screwed into the mounting screw hole through the threaded rod to limit the position of the bottom mounting plate and the power supply body.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem of inconvenient disassembly and assembly during the operation of the DC power supply by arranging a bottom mounting plate, a power supply body and a rotating frame. The threaded rod at the bottom end of the rotating frame is aligned with the movable hole on the fixed frame, inserted into the movable hole, and then screwed into the mounting screw hole on the bottom mounting plate. After tightening, the installation of the power supply body is completed. When disassembling the power supply body, the rotating frame is directly rotated to drive the threaded rod to be screwed out of the mounting screw hole, and then the pulling handle is pulled to pull the power supply body out from between the bottom mounting plate and the water cooling plate to complete the disassembly of the power supply body, making it more convenient to disassemble and assemble the DC power supply during operation.

[0015] 2. The utility model solves the problem of large heat dissipation noise during operation of the DC power supply by setting a bottom mounting plate, a power supply body and a water cooling plate. When the power supply body is installed on the bottom mounting plate, the bottom of the water cooling plate is in close contact with the top of the power supply body. The water cooling plate is started, and the heat generated by the power supply body when it is working is absorbed, so that the heat dissipation noise is smaller and the operation is quieter during the operation of the DC power supply.
