Description

Technical Field

[0001] The utility model relates to the technical field of direct current power supply monitoring equipment, and more specifically, to a wall-mounted direct current power supply monitoring equipment. Background Art

[0002] The wall-mounted DC power supply is suitable for small switch stations, small user substations and small 10KV substation systems. The system adopts an integrated design concept and consists of a rectifier module, a monitoring module, a step-down unit, a distribution unit and a battery installation box. It has the characteristics of small size, simple structure, and independent system. However, the existing wall-mounted DC power supply equipment is usually exposed to the outside and is prone to dust accumulation inside, which will affect the service life of the equipment.

[0003] The utility model patent with patent publication number CN214703930U discloses a wall-mounted DC power supply monitoring device. The advantage of this structure is that by setting a mounting block, the operator can easily install the device at any position, reducing the difficulty of disassembly and assembly to meet different monitoring needs. The protective shell, cross plate and ball bearings set up facilitate the later replacement and maintenance of the monitoring equipment, and also play a protective role.

[0004] However, in actual use, although this structure is convenient for installing the equipment, because the equipment is directly installed on the L-shaped base inside the protective shell, and when the equipment needs to be repaired, the equipment needs to be removed from the protective shell and then installed inside the protective box after repair. This process is time-consuming, and because the equipment is hung on the wall, it is easy to cause the equipment to fall during installation, which will affect the normal use of the equipment.

[0025] As attached Figure 1 , 2As shown, a baffle 17 is provided on one side of the pressure plate 7 and located on one side of the protection box 1, and positioning rods 18 are provided on one side of the baffle 17 and located on both sides of the pressure plate 7. Positioning holes are opened on the surface of the protection box 1 and on both sides of the slot, and the two positioning rods 18 are engaged with the positioning holes. By separating the positioning rods 18 from the positioning holes, the pressure plate 7 can be taken out from the inside of the slot, and the restriction on the power cord can be released.

[0026] As attached Figure 1 , 2 As shown, multiple mounting plates 19 are provided on both sides of the protection box 1, and mounting holes are provided on the surfaces of the multiple mounting plates 19. The protection box 1 can be fixed on the wall through the mounting holes and screws.

[0031] When the power supply device moves, the elasticity of the second spring inside the connecting tube 20 inside the fixed frame 3 can generate a driving force on the connecting rod 21, so that the connecting rod 21 drives the limit plate 22 to move, and the roller 23 on one side of the limit plate 22 is in contact with the surface of the monitoring device body 2, so that friction is generated between the power supply device and the roller 23, which can not only limit the two sides of the monitoring device body 2, but also reduce the friction between the monitoring device body 2 and the limit plate 22. The utility model can directly move the monitoring device body 2 out of the protective box 1 through the moving plate 4, and can support the moving plate 4 through the stretching rod 11. The power cord can be squeezed and fixed through the pressing plate 7 and the arc plate 14, which is conducive to facilitating the maintenance of the monitoring device body 2 and avoiding the transportation and disassembly of the monitoring device body 2.
