Description

Technical Field

[0001] The utility model relates to the technical field of direct current screens, in particular to a direct current screen with a wall-mounted structure. Background Art

[0002] The DC panel is a new type of DC system with digital control, protection, management and measurement. The DC power panel can provide a stable DC power supply. The current DC panel is generally installed in a cabinet. The cabinet-mounted DC panel is equipped with a base that can be directly placed on the ground, but it is large in size and inconvenient to disassemble. It is suitable for large switch stations and substations with large loads. In order to adapt to small switch stations, small user substations and small 10KV substation systems, a wall-mounted DC panel is designed. It adopts an integrated design concept and is generally composed of a rectifier module, a monitoring module, a step-down module, a distribution module and a battery installation box. It has the characteristics of small size, simple structure, and independent system.

[0003] The existing suspended DC screens are all fixed directly on the wall or column with bolts. After a period of use, the fixing bolts on the DC screen will loosen due to vibration, causing the DC screen to detach. The DC screen directly installed on the wall is close to the wall, which is not conducive to the heat dissipation of the wall-mounted DC screen. In addition, the location of the suspended DC screen is not convenient for frequent cleaning, and a lot of dust is easily accumulated on the surface. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the present embodiment provides a DC screen with a wall-mounted structure, comprising a wall mount 1, a DC screen body 3 and a shell 31 for installing the DC screen body 3, the wall mount 1 is a rectangular frame structure, a pair of plug blocks 12 are symmetrically fixed on the upper end of the wall mount 1, a pair of sockets 2 matched with the plug blocks 12 are fixedly connected to the back of the shell 31, and a vertical card slot 21 engaged with the plug block 12 is provided on the lower end surface of the socket 2; the plug block 12 is an L-shaped structure, and the cross-section of one end of the plug block 12 connected to the card slot 21 is an isosceles trapezoid, and the relative inner walls of the card slot 21 are provided with horizontal slideways 23, and the slideways 23 are slidably connected with movable blocks 22, and the two movable blocks 22 are respectively arranged on both sides of the plug block 12, and a spring 24 is connected between one end of the movable block 22 and the inner wall of the slideway 23; the side of the movable block 22 that matches the end of the plug block 12 is an inclined surface. Slide grooves 4 are provided on the front of the shell 31 and at the top and bottom of the DC screen body 3, and sliders 5 are movably installed inside the two slide grooves 4. Fixed rods 6 are fixedly installed on the opposite sides of the two sliders 5, and dust-absorbing cotton is fixedly installed on the back of the fixed rods 6; bearings with seats are fixedly installed on the left and right sides of the top of the shell 31, and a shaft rod 10 is installed between the bearings with seats, a dustproof cloth 100 is wound on the shaft rod 10, and a motor 8 is connected and installed on the outer end of the shaft rod 10.

[0024] A sealing gasket 7 is fixedly installed inside the shell 31, and a DC screen body 3 is fixedly installed on the inner back wall of the shell 31 and located behind the sealing gasket 7. The sealing gasket 7 fills the gap to prevent the gap between the DC screen body 3 and the shell 31 from being filled with dust.

[0025] An armature 101 is fixedly mounted on the lower end of the dustproof cloth 100. The armature 101 has weight, and when the dustproof cloth 100 sags, the armature 101 ensures the straightness of the dustproof cloth 100 under the action of gravity.

[0026] The output end of the motor 8 passes through a seat bearing 9 on one side and is fixedly connected to the shaft 10 .

[0027] The length of the chute 4 is greater than the length of the housing 31 and less than the length of the DC screen body 3 .

[0028] A pair of support plates 11 for supporting the bottom surface of the housing 31 are fixedly connected to the lower end of the wall mount 1. A pair of support blocks 13 are provided below the insert block 12 on the wall mount 1.

[0029] The motor 8 drives the shaft 10 to rotate forward and reverse inside the seat bearing 9, thereby controlling the dustproof cloth 100 outside the shaft 10 to rise or fall. The armature 101 on the dustproof cloth 100 is arranged vertically, so that the dustproof cloth 100 can better play a dustproof role.

[0030] Furthermore, by sliding the slider 5, the fixing rod 6 and the dust-absorbing cotton on the back are driven to slide on the surface of the DC screen body 3, thereby achieving the purpose of cleaning dust.

[0031] During installation, the wall mount 1 is fixedly connected to the wall by expansion bolts. After the DC screen body 3 is installed inside the shell 31, it is matched with the socket 2 and the plug block 12. After the plug block 12 squeezes the movable block 22, when the DC screen vibrates, the plug block 12 will push the movable block 22 to move in the groove 23, and the spring 24 applies elastic force to the movable block 22 and restores the movable block 22 to its initial position, thereby improving the vibration reduction effect on the DC screen. After installation by the wall mount 1, a space is formed between the DC screen and the wall, which is beneficial to the heat dissipation of the DC screen. In the present invention, a pair of movable blocks are symmetrically connected through the inner wall of the wall mount slot, a spring is connected between the movable block and the inner wall of the slot, and the end of the movable block is set as an inclined surface. When the whole vibrates, the plug block will push the movable block to move in the groove, and the spring applies elastic force to the movable block and restores the movable block to its initial position, thereby improving the overall vibration reduction effect and ensuring the connection effect between the DC screen and the wall. At the same time, a space is formed between the DC screen and the wall, which is beneficial to the heat dissipation of the DC screen.
