Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinets, in particular to an electric control cabinet for a thermal power plant. Background Art

[0002] An electrical control cabinet is a device specifically used to control and protect electrical equipment and circuits. It is mainly used in various fields such as industrial automation systems, power systems, transportation systems, building systems, etc. to distribute, control, protect and monitor circuits. It is an indispensable part of modern electrical systems and has important functions and roles. Electrical control cabinets are usually controlled by relays and PLCs. Simple ones can be controlled by relays, and more complex ones must be controlled by PLCs. Different electrical components can be selected to form a cabinet according to the size and number of the controlled equipment. In addition, the electrical control cabinet has a variety of control functions, such as start and stop control functions, frequency (speed) adjustment functions, meter display functions, standby power frequency switching functions, etc.

[0003] The electrical control cabinets of current thermal power plants, when in use, will have too high a temperature inside the cabinet as the height increases, and the inside of the cabinet needs to be cooled. However, during the cooling process, most fans generally cool in a fixed direction and do not have a wide range of steering functions, resulting in poor cooling and dust removal effects. In addition, the fan draws air through the air inlet, causing dust in the air to enter the cabinet, causing dust accumulation and affecting the use of the control cabinet. Therefore, a filter is required to filter the dust, and it needs to be cleaned regularly. However, the removal of the filter is relatively complicated, which greatly affects work efficiency.

[0027] The steering component 2 includes: a motor 211 fixedly connected to the top of the cabinet 1; and a steering box 213 fixedly connected to the inside of the cabinet 1 through a fixing seat.

[0028] The output end of the motor 211 passes through the top of the cabinet 1 and is fixedly connected with a connecting block 212 . The inner center of the steering box 213 is movably connected with a ball bearing 214 . The inner part of the steering box 213 is fixedly connected with a limit plate 215 .

[0029] One end of the connecting block 212 is fixedly connected to a connecting rod 217 , one end of the connecting rod 217 passes through the ball bearing 214 and is fixedly connected to a motor 218 , and an output end of the motor 218 is fixedly connected to a fan 219 .

[0030] The outer wall of the ball bearing 214 is fixedly connected with a connecting plate 216 , and the connecting plate 216 is matched with the limiting plate 215 .

[0031] Furthermore, in the embodiment, the motor 211 is driven to rotate the connecting block 212 at the output end of the motor 211, thereby driving the connecting rod 217 to rotate with the ball 214 as the axis. While the ball 214 rotates, the connecting plate 216 rotates stably under the restriction of the limit plate 215, thereby achieving the effect of stable rotation of the connecting rod 217, driving the motor 218, and rotating the fan 219 at the output end of the motor 218, thereby achieving the effect of increasing the blowing range of the fan 219.

[0032] Example 2

[0033] The utility model provides a technical solution: Figure 1-Figure 5 As shown: the filter component 3 includes: a slide rail 311, which is fixedly connected to the top of the cabinet 1 and is equidistantly arranged; a filter plate 312, which is slidably connected to the inside of the slide rail 311, the filter plate 312 is adapted to the air inlet, and a card slot is opened on one side of the filter plate 312.

[0036] Furthermore, in the embodiment, by inserting the filter plate 312 into the slide rail 311, due to the appearance characteristics of the triangular clamping block 316, the triangular clamping block 316 is squeezed until the clamping groove is engaged with the triangular clamping block 316, thereby achieving the effect of quickly fixing the filter plate 312. When the filter plate 312 needs to be disassembled and cleaned, the pressing rod 314 is pressed to make the pressing rod 314 slide downward along the track of the fixed rail 313, so that under the action of the brake block 315, the transmission block 317 is squeezed to make the transmission block 317 slide along the track of the slide groove, thereby achieving the effect of simultaneously contracting the triangular clamping blocks 316 at both ends and quickly disassembling.

[0037] Working principle: First, the motor 211 is driven to rotate the connecting block 212 at the output end of the motor 211, thereby driving the connecting rod 217 to rotate with the ball 214 as the axis. While the ball 214 rotates, the connecting plate 216 is stably rotated under the restriction of the limit plate 215, thereby achieving the effect of stable rotation of the connecting rod 217, driving the motor 218 to rotate the fan 219 at the output end of the motor 218, thereby achieving the effect of increasing the blowing range of the fan 219; secondly, the filter plate 312 is inserted into the slide rail 311 Due to the appearance characteristics of the triangular clamping block 316, the triangular clamping block 316 is squeezed until the clamping groove is engaged with the triangular clamping block 316, thereby achieving the effect of quickly fixing the filter plate 312. When the filter plate 312 needs to be disassembled and cleaned, the pressing rod 314 is pressed to make the pressing rod 314 slide downward along the track of the fixed rail 313, so that under the action of the brake block 315, the transmission block 317 is squeezed to make the transmission block 317 slide along the track of the slide groove, so that the triangular clamping blocks 316 at both ends are simultaneously contracted and quickly disassembled.
