Description

[0001] The invention relates to the technical field of production related to power cabinets, and in particular to a power cabinet capable of preventing dust and reducing temperature. Background Art

[0002] As an important part of the power system, power cabinets are widely used in power plants, substations, industrial and mining enterprises, etc. They can be used for the distribution, control and protection of electric energy to ensure the safe, stable and efficient operation of the power system. When the outside air is guided into the power cabinet through fans and other equipment to cool the power cabinet and the electronic components inside the power cabinet, in order to ensure the stable operation of the electronic components inside the power cabinet, a filter needs to be set at the fan to block the dust entering the device and protect the electronic components. During the use of the existing filter, in order to avoid clogging of the filter by dust, a brush plate needs to be set on the surface of the filter to clean the surface of the filter. However, the power equipment of the existing fan and the power equipment of the brush plate are set independently of each other, which not only increases the manufacturing cost of the equipment, but also increases the energy consumption of the equipment.

A second rotating rod 22 is rotatably installed in the first rotating rod 21. Fan blades 23 and brush plates 24 are fixedly installed on the lower end surfaces of the first rotating rod 21 and the second rotating rod 22 respectively. The fan blades 23 and the brush plates 24 are respectively arranged on the upper and lower sides of the filter screen 2. A first motor box 27 is fixedly installed on the upper end surface of the connecting pipe 15. A first driven bevel gear 25 and a second driven bevel gear 26 are fixedly installed on the periphery of the first rotating rod 21 and the second rotating rod 22 respectively. A driving bevel gear 28 meshing with the first driven bevel gear 25 and the second driven bevel gear 26 is fixedly installed on the outer end surface of the first motor box 27 through its output shaft.

[0020] Specifically, when cooling the interior of the cabinet 1, the motor inside the first motor box 27 is started, and the active bevel gear 28 can be driven to rotate through the output shaft at the outer end thereof, and then the meshing effect between the active bevel gear 28 and the first driven bevel gear 25 and the second driven bevel gear 26 makes the first motor box 27 simultaneously drive the first rotating rod 21 and the second rotating rod 22 to rotate, thereby respectively driving the fan blades 23 and the brush plate 24 to rotate on the upper and lower sides of the filter 2, and the rotating fan blades 23 can guide the outside air into the dust collector 16 and the cabinet 1 in turn, so as to achieve the effect of cooling the electronic components inside the cabinet 1, and the filter 2 can be provided to block the dust entering the dust collector 16, and the filter 2 can be cleaned by the rotating brush plate 24 to prevent the dust from clogging the lower end surface of the filter 2; Among them, an air inlet chamber 13 and an air exhaust chamber 14 are set, and a first electrically controlled valve 181 and a second electrically controlled valve 191 are respectively set at the air inlet inner pipe 18 and the exhaust inner pipe 19 on both sides of each compartment.

[0021] In another embodiment provided by the present invention, the upper end surface of the connecting tube 15 is fixedly installed with the limit seat 3 through the connecting plate, and the second rotating rod 22 includes an upper rotating rod 221 and a lower rotating rod 222, and the upper rotating rod 221 and the lower rotating rod 222 are respectively rotatably installed on the upper and lower sides of the limit seat 3, and the upper end surface of the lower rotating rod 222 is fixedly installed with a first driven gear ring 31 rotatably connected to the lower end surface of the limit seat 3, and the lower end surface of the upper rotating rod 221 is fixedly installed with a driving gear 32, and the driving gear 32 is rotatably installed in the first driven gear ring 31, and the lower end surface of the limit seat 3 is rotatably installed with a plurality of planetary gears 34, and the two sides of the planetary gears 34 are respectively meshed with the first driven gear ring 31 and the driving gear 32.

[0022] Specifically, since the second rotating rod 22 is divided into an upper rotating rod 221 and a lower rotating rod 222, the rotating active bevel gear 28 can drive the upper rotating rod 221 to rotate, and then through the meshing effect between the planetary gear 34 and the first driven gear ring 31 and the active gear 32, the upper rotating rod 221 can reduce the rotation speed of the lower rotating rod 222 when driving the lower rotating rod 222 to rotate, so that the rotation speed of the brush plate 24 is lower than that of the fan blades 23, and then when the fan blades 23 rotate at high speed, the slowly rotating brush plate 24 will not affect the falling of dust at the lower end of the filter 2.

[0023] In another embodiment provided by the present invention, the lower end surface of the dust collector 16 is interconnected with the outside world, a dust collecting frame 162 is installed on the lower end surface of the cabinet 1, and a guide ring 4 fixedly connected to the inner wall of the cabinet 1 is provided on the upper side of the dust collecting frame 162. The air inlet outer pipe 161 is arranged between the guide ring 4 and the filter screen 2. A rotating disk 41 is rotatably installed on the lower end surface of the guide ring 4. A dust guiding cavity 42 is opened in the middle of the guide ring 4 and the rotating disk 41. A plurality of sealing blocks 43 that fit each other are slidably installed at equal intervals between the guide ring 4 and the rotating disk 41, and a limiting slider is fixedly installed on the upper and lower end surfaces of each sealing block 43. 44 and a limiting slide shaft 45, the lower end surface of the guide ring 4 is provided with a plurality of limiting slide grooves 441 which are respectively slidably connected to each limiting slide block 44, the upper end surface of the rotating disk 41 is provided with a plurality of arc-shaped slide grooves 451 which are respectively slidably connected to each limiting slide shaft 45, the limiting slide shaft 45 is arranged in a cylindrical shape, and the arc-shaped slide grooves 451 are arranged obliquely, and a second driven gear ring 47 is fixedly installed on the lower end surface of the rotating disk 41, and a second motor box 46 is fixedly installed in the dust collector 16, and a driving gear 48 which is meshed and connected to the second driven gear ring 47 is fixedly installed on the upper end surface of the second motor box 46 through its output shaft.

[0024] Specifically, when the sealing block 43 expands outward, the dust guide cavity 42 can be opened, so that the dust falling from the lower end surface of the filter 2 can enter the dust collecting frame 162 through the dust guide cavity 42, and the dust collecting frame 162 installed by plugging can be recovered. When the sealing block 43 contracts inward, the dust guide cavity 42 can be sealed, and when the fan blade 23 rotates, the dust inside the dust collecting frame 162 can be prevented from flowing back upward to the filter 2; When adjusting the contraction and expansion states of the sealing block 43, the motor inside the second motor box 46 is started, and the driving gear 48 can be driven to rotate through its outer output shaft, and the meshing effect between the driving gear 48 and the second driven gear ring 47 can drive the rotating disk 41 to rotate at the lower end of the guide ring 4. In the inner cavity of the guide ring 4, the sliding cooperation between the limiting slider 44 and the limiting groove 441 restricts the movement direction of each sealing block 43, so that the rotating rotating disk 41 can drive each sealing block 43 to contract inward or expand outward through the sliding cooperation between the cylindrical limiting slide shaft 45 and the inclined arc groove 451, so as to achieve the effect of opening or closing the dust guide chamber 42.

[0025] In another embodiment provided by the present invention, temperature sensors 10 are fixedly installed on the upper end surfaces of each compartment in the inner cavity of the cabinet body 1, a cabinet door 11 is rotatably installed on the front end surface of the cabinet body 1, an operation panel 12 is fixedly installed on the front end surface of the cabinet door 11, a processor 121 is fixedly installed in the operation panel 12, and the processor 121 is electrically connected to the operation panel 12, the temperature sensor 10 and the first electric control valve 181, the second electric control valve 191, the first motor box 27, and the second motor box 46 through wires.

[0026] Specifically, an operation panel 12 is provided, which can be used to check the operation status of the electronic components inside the device and to control the temperature specified digital of the processor 121. A temperature sensor 10 is provided in each insulation inside the cabinet 1. Through the temperature sensor 10, the temperature in each compartment can be sensed respectively, and the temperature value information is transmitted to the processor 121. When the value monitored by the temperature sensor 10 inside each compartment exceeds the specified value set inside the processor 121, the processor 121 transmits the information to the first motor box 27 and the first electric control valve 181 and the second electric control valve 191 on both sides of the corresponding compartment. The fan blades 23 are started to rotate by the first motor box 27, so that the outside air can be guided into the air inlet chamber 13. Since the first electric control valve 181 and the second electric control valve 191 on both sides of the corresponding compartment are opened, the air inside the air inlet chamber 13 can be injected into the corresponding compartment, and the air inside the compartment is discharged to the outside through the exhaust chamber 14, so that the interior of the compartment can be cooled down, and the electronic components inside each compartment can be kept warm for stable operation. Among them, when the motor inside the first motor box 27 is turned on, the processor 121 can start the motor inside the second motor box 46, driving each sealing block 43 to shrink inward, so as to achieve the effect of closing the dust guide chamber 42, and prevent the dust inside the dust collecting frame 162 from flowing upward. When the motor inside the first motor box 27 is turned off, the processor 121 can drive each sealing block 43 to expand outward through the second motor box 46, so as to open the dust guide chamber 42. Since the motor inside the first motor box 27 is turned off, the fan blades 23 are also in a stationary state. At this time, the dust inside the dust collector 16 will naturally fall into the dust collecting frame 162, so that the dust can be recovered.

[0027] Working principle: The specified temperature value inside each compartment is input into the processor 121 through the operation panel 12. The temperature inside the compartment can be monitored through the temperature sensor 10 on the upper side of the compartment cavity. In the compartment inside the cabinet 1, when the temperature inside the compartment rises due to the operation of electronic components, the temperature sensor 10 in the compartment can transmit the temperature information to the processor 121 in real time. The processor 121 starts the motors inside the first motor box 27 and the second motor box 46 and the first electric control valve 181 and the second electric control valve 191 on both sides of the compartment. The motor inside the second motor box 46 drives the rotating disk 41 to rotate through its output shaft, driving gear 48 and second driven gear ring 47 in turn, and then the sliding cooperation between the sealing block 43 and the guide ring 4 and the rotating disk 41 makes the rotating rotating disk 41 drive each sealing block 43 to shrink inward, so as to seal the dust guide chamber 42. The first motor box 27 drives the dust guide chamber 42 through its output shaft, driving bevel gear 28, first driven bevel gear 25 and second driven gear ring 47 in turn. The two driven bevel gears 26 and the first rotating rod 21 and the second rotating rod 22 can respectively drive the fan blades 23 and the brush plate 24 to rotate. Through the rotating fan blades 23, the outside air can be guided into the dust collector 16 at the air inlet outer pipe 161, and then the air is guided into the air inlet chamber 13 through the connecting pipe 15. Since the first electric control valve 181 and the second electric control valve 191 on both sides of the corresponding compartment have been opened, the air can be injected into the compartment through the air inlet inner pipe 18 and the exhaust inner pipe 19, and the compartment is The air inside the compartment is guided to the exhaust chamber 14 and then discharged to the outside, so as to achieve the effect of cooling the electronic components inside the corresponding compartment; the filter 2 is set to block the dust in the air in the dust collector 16, and due to the meshing effect between the planetary gear 34 and the first driven gear ring 31 and the driving gear 32, the brush plate 24 is lower than the fan blade 23, and the lower end surface of the filter 2 can be cleaned by the slowly rotating brush plate 24 to avoid clogging of the lower end surface of the filter 2 by dust; After the temperature inside the compartment returns to normal, the temperature sensor 10 inside the compartment transmits information to the processor 121, and the processor 121 closes the motor inside the first motor box 27 and the corresponding first electric control valve 181 and the second electric control valve 191, thereby limiting the air circulation between the inside of the device and the outside world. At the same time, the processor 121 starts the motor inside the second motor box 46 again, and through its output shaft, it can drive the rotating disk 41 to rotate in the opposite direction, thereby driving each sealing block 43 to expand outward and open the dust guide chamber 42. Since the fan blades 23 are in a stationary state at this time, the dust at the lower end of the filter 2 can fall naturally and enter the dust collecting frame 162 through the dust guide chamber 42, so that the dust can be recovered.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
