Description

Technical Field

[0001] The utility model belongs to the technical field of DC panel cabinets, and particularly relates to a DC panel cabinet with heat dissipation and waterproof functions. Background Technique

[0002] The DC panel is short for the DC operation power supply system, and its general name is the intelligent maintenance-free DC power supply panel, abbreviated as the DC panel. Nowadays, DC power supplies are used for the power operation power supplies in power plants and substations. It provides power for control loads, power loads, and DC accident lighting loads, etc., and is the basis for the control and protection of contemporary power systems. The DC panel consists of an AC and DC distribution unit, a charging module unit, a step-down silicon chain unit, a DC power feeding unit, a power distribution monitoring unit, a monitoring module unit, and an insulation monitoring unit. It is mainly applied to small and medium-sized power plants, hydropower stations, various substations in the power system, and other users using DC equipment (such as petrochemical, mining, railway, etc.), and is suitable for occasions such as switch closing and opening, and instruments, meters, relay protection, and fault lighting in the secondary circuit.

[0003] In the process of using the existing DC panel cabinets, heat dissipation holes are usually opened to assist the device in heat dissipation. Relying solely on the heat dissipation holes for heat dissipation, the heat dissipation effect is average. At the same time, the heat dissipation holes opened for heat dissipation are usually not provided with protection, which easily leads to dust accumulation in the heat dissipation holes and affects the subsequent heat dissipation of the heat dissipation holes. At the same time, for the existing DC panel cabinets, they need to be installed at a designated position according to the usage requirements, such as outdoors. For the DC panel cabinets installed outdoors, a waterproof cover is usually set above the cabinet body. Most of the waterproof covers are fixed and cannot be retracted and folded according to the usage requirements. Therefore, we need to upgrade and transform on the basis of the existing technology.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes, and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 - Figure 5As shown in the figure, a heat-dissipating and waterproof DC panel cabinet provided in this embodiment includes a device body 1. The device body 1 includes an outer shell 2 and an electric cabinet 5. The electric cabinet (5) is arranged in the internal space of the outer shell (2). The upper end of the outer shell 2 is provided with a top plate 7, and a placement groove 20 and a mounting groove 22 are opened in the outer shell 2. A support frame 8 is arranged below the top plate 7. One end of the support frame 8 is installed with a worm gear 9. A worm 10 is meshed on the side of the worm gear 9, and a first bevel gear 13 is connected to the rear end of the worm gear 9. One end of the first bevel gear 13 is connected to a winding rod 12, and a second bevel gear 14 is meshed below the first bevel gear 13. A rainproof cloth 16 is sleeved on the winding rod 12. A reinforcing plate 17 is installed below the rainproof cloth 16. A mounting plate 15 and a first connecting rod 18 are connected below the second bevel gear 14. A second connecting rod 19 is movably installed below the reinforcing plate 17. A knob 11 is connected below the worm 10. An electric fan 21 is installed in the placement groove 20. A mounting frame 23 is arranged in the mounting groove 22, and a dust-proof net 24 is arranged in the mounting frame 23.

[0025] Preferably, a cabinet door 3 is hinged to the front end of the outer shell 2, and a transparent glass is installed in the cabinet door 3. By providing the cabinet door 3, the electric cabinet 5 inside the outer shell 2 can be protected and it is convenient to observe the operation condition of the electric cabinet 5. A handle 4 is installed at the front end of the cabinet door 3, and the handle 4 is fixedly connected to the cabinet door 3. By providing the handle 4, it is convenient for the user to open and close the cabinet door 3, which provides convenience for the user. Two groups of the first connecting rod 18 and the second connecting rod 19 are fixedly and symmetrically arranged. The connection between the first connecting rod 18 and the second connecting rod 19 is rotatably connected, which increases the connection and intimacy between the devices and is convenient for the user to control the devices.

[0026] Preferably, heat dissipation holes 6 are opened on the electric cabinet 5. Multiple groups of heat dissipation holes 6 are opened, and the heat dissipation holes 6 are long strip rectangles. By opening the heat dissipation holes 6, the heat generated by the operation of the device can be dissipated, avoiding heat accumulation of the device and affecting the subsequent use of the device. Screw holes 25 are opened in both the mounting frame 23 and the mounting groove 22, and fastening bolts 26 are screwed in the screw holes 25. By providing the fastening bolts 26, the mounting frame 23 can be fixed and limited, ensuring the safety of the mounting frame 23 during use.

[0027] The working principle and process of the present utility model are as follows: When in use, the electric cabinet 5 in the control device operates, and heat is generated during the operation of the device. The generated heat is exchanged with the external air through the opened heat dissipation holes 6, thereby dissipating the heat inside the device. During the heat dissipation process, the electric fan 21 can be turned on. The operation of the electric fan 21 can assist the device in more quickly evacuating the heat inside the device. When dust prevention is required for the device during heat dissipation, the outer casing 2 is grooved, the dust-proof net 24 is welded in the mounting frame 23, and the mounting frame 23 with the dust-proof net 24 is placed in the mounting groove 22 of the outer casing 2. After placing it in the appropriate position, the fastening bolt 26 is screwed into the screw hole 25. At this time, the dust-proof net 24 is fixed. Conversely, the dust-proof net 24 can be disassembled and cleaned, which can provide dust-proof protection for the device, reduce the situation of dust entering the device through the heat dissipation holes 6, and avoid the problem that the heat dissipation holes 6 are blocked and affect the subsequent heat dissipation of the device. When it rains during the use of the device, the user rotates the knob 11 by hand. When the knob 11 rotates, it drives the worm 10 to rotate. When the worm 10 rotates, it drives the worm gear 9 to rotate. When the worm gear 9 rotates, it drives the bevel gear one 13 and the winding rod 12 to rotate. When the bevel gear one 13 rotates, it meshes with the bevel gear two 14 below and rotates. When the winding rod 12 rotates, it drives the rain shield 16 to stretch outwards. During the stretching process, the reinforcement plate 17 moves accordingly. When the reinforcement plate 17 moves, it drives the second connecting rod 19 to stretch outwards. When the second connecting rod 19 stretches outwards, it drives the first connecting rod 18 to stretch until the rain shield 16 is stretched to the appropriate position, and rain protection can be achieved. Conversely, the rain shield 16 can be retracted and folded, which can provide waterproof protection for the device, reduce the situation of water entering the cabinet, ensure the safety of the device, facilitate the storage and folding of the rain shield 16, and avoid the problem that the rain shield 16 occupies too much space and affects the aesthetics of the device.
