[0003] At present, the existing noise reduction and diversion device based on high-voltage frequency converter generally includes a high-voltage frequency converter and a first ventilation plate. The first ventilation plate is installed on the front side of the high-voltage frequency converter. When the high-voltage frequency converter is started, the noise and airflow transmitted from the high-voltage frequency converter are transmitted into the fixed plate.

However, the efficiency of noise reduction and diversion of the noise and airflow transmitted from the vents on both sides of the device is relatively low, and the operation of cleaning the dust generated in the process of transmitting noise and airflow is relatively laborious.

Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0040] Example 1

[0041] A noise reduction and flow guiding device based on a high voltage inverter, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, it includes a high-voltage inverter 1, a first ventilation plate 2, a guide mechanism 3 and a noise reduction mechanism 4. The front side of the high-voltage inverter 1 is connected to the first ventilation plate 2, and the left and right sides of the high-voltage inverter 1 are also connected to the first ventilation plates 2. The lower part of the high-voltage inverter 1 is fixedly connected to the guide mechanism 3, and the front side of the upper part of the high-voltage inverter 1 is fixedly connected to the noise reduction mechanism 4.

[0042] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the guide mechanism 3 includes a fixing frame 31, a fixing plate 32, a baffle 33, a filter plate 34, a first air suction device 35, a first connecting plate 36, a support frame 37, a ventilation pipe 38, a second air suction device 39, a guide plate 310 and an exhaust plate 311. The lower part of the high-voltage inverter 1 is fixedly connected to the fixing frame 31 by screws, and the fixing plate 32 is fixedly connected between the left and right ends of the upper part of the high-voltage inverter 1 by bolts. The baffle 33 is fixedly connected to the left and right ends of the fixing plate 32 by bolts. The upper left part of the fixing plate 32 is fixedly connected to the baffle 33 by bolts. Filter plates 34 are connected to both right sides, and two first air suction devices 35 are connected to the lower parts of the two filter plates 34. A first connecting plate 36 is fixedly connected between the upper parts of the fixing plates 32 by bolts. The upper part of the front side of the high-voltage inverter 1 is fixedly connected to the support frame 37 by screws, and the upper part of the front side of the support frame 37 is rivetedly connected to a ventilation pipe 38, and the rear side of the ventilation pipe 38 is connected to a second air suction device 39. Two guide plates 310 are fixedly connected in the ventilation pipe 38 by bolts, and an exhaust plate 311 is welded to the front side of the ventilation pipe 38.

[0043] like Figure 7 and Figure 8 As shown, the noise reduction mechanism 4 includes a fixed frame 41, a pull plate 42, a first connecting frame 43 and a V-shaped plate 44. The middle part of the upper side of the support frame 37 is fixedly connected with the fixed frame 41 by screws, the pull plate 42 is snap-connected inside the fixed frame 41, the upper part of the fixed frame 41 is fixedly connected with the first connecting frame 43 by screws, and the inside of the first connecting frame 43 is connected with the V-shaped plate 44.

[0044] When people need to reduce the noise and guide the high-voltage frequency converter 1, people can start the high-voltage frequency converter 1, and the noise and airflow transmitted by the high-voltage frequency converter 1 are then transmitted into the fixed plate 32. People can start the first air suction device 35, and the first air suction device 35 then transmits the transmitted noise and airflow into the middle part of the upper side of the fixed plate 32. Under the filtering effect of the filter plate 34, the noise emitted by the high-voltage frequency converter 1 can be filtered, so that the noise emitted by the high-voltage frequency converter 1 can be reduced. The airflow is then sucked into the middle part of the upper side of the fixed plate 32, and the second air suction device 39 is started. The airflow generated by the noise reduction of the second air suction device 39 is then transmitted to the ventilation pipe. 38, under the guidance of the two guide plates 310, the airflow in the ventilation pipe 38 is transmitted into the first connecting frame 43. Under the blocking effect of the V-shaped plate 44 in the first connecting frame 43, the dust and impurities generated by the airflow in the first connecting frame 43 fall on the V-shaped plate 44, and the airflow is discharged from the exhaust plate 311. After the airflow is discharged, the first suction device 35 is closed, and the airflow stops transmitting to the middle part of the upper side of the fixed plate 32, and then the second suction device 39 is closed. In this way, the high-voltage inverter 1 can be more conveniently denoised and diverted, thereby improving the efficiency of people's denoising and diverting the high-voltage inverter 1.

[0045] Example 2

[0046] On the basis of Example 1, Fig. 9 and Fig.10 As shown, a cooling mechanism 5 is also included, and the cooling mechanism 5 includes a second connecting plate 51, a second ventilation plate 52 and a cooling fan 53. The left and right ends of the high-voltage inverter 1 are fixedly connected with the second connecting plates 51 by bolts, and the two second connecting plates 51 are welded with the second ventilation plates 52. The insides of the two second connecting plates 51 are connected with two cooling fans 53 by bolts.

[0047] During the use of the high-voltage inverter 1, the cooling fan 53 is started, and the cooling fan 53 rotates accordingly, and the airflow transmitted from the high-voltage inverter 1 is transmitted into the second connecting plate 51. Under the cooling effect of the cooling fan 53, the airflow transmitted into the second connecting plate 51 can be cooled down. After the cooling is completed, the airflow in the second connecting plate 51 is discharged from the second ventilation plate 52, and the discharged airflow is transmitted into the fixed plate 32. Then people can turn off the cooling fan 53, and the cooling fan 53 stops cooling. In this way, the airflow transmitted from the high-voltage inverter 1 can be cooled down more conveniently, thereby avoiding excessive temperature during the noise reduction and diversion process of the high-voltage inverter 1, affecting the efficiency of the noise reduction and diversion of the high-voltage inverter 1, thereby providing convenience for the noise reduction and diversion operation of the high-voltage inverter 1.

[0048] Example 3

The lower parts of the inner sides of the two fixed plates 32 are slidably connected to the dust collectors 64, and the telescopic tubes 63 are connected between the two dust collectors 64 and the two discharge ports 62. The front sides of the two dust collectors 64 are fixedly connected to the first connecting block 65 by screws.

The front sides of the two fixed plates 32 are connected to the rodless cylinder 66 by bolts, and the rodless cylinder 66 is slidably connected to the first connecting block 65.

[0050] When the airflow transmitted from the high-voltage inverter 1 is transmitted to the fixed plate 32, people can start the rodless cylinder 66, and the rodless cylinder 66 will drive the first connecting block 65 to slide upward. Under the sliding cooperation of the first connecting block 65 and the fixed plate 32, the dust collector 64 will slide upward, and the telescopic tube 63 will stretch accordingly. The dust on the surface of the second ventilation plate 52 will be sucked into the dust collector 64, and the dust sucked into the dust collector 64 will fall into the telescopic tube 63, and the dust in the telescopic tube 63 will fall into the discharge port 62, and the dust in the discharge port 62 will fall into the second connecting frame 61. People can manually take out the second connecting frame 61 to deal with the dust in the second connecting frame 61. After the dust on the surface of the second ventilation plate 52 is cleaned, the rodless cylinder 66 will drive the suction dust collector 64 to reset, and the telescopic tube 63 will shrink accordingly, so that the dust on the surface of the second ventilation plate 52 can be cleaned, thereby preventing the dust from affecting the flow of airflow, thereby providing convenience for people to clean the dust on the surface of the second ventilation plate 52.

[0051] Example 4

[0052] On the basis of Example 3, Fig.14 As shown, a wiping mechanism 7 is also included, which includes a third connecting plate 71, a spring 72 and a wiping rod 73. The springs 72 are connected to the left and right sides of the upper part of the fixed frame 41, and the third connecting plate 71 is fixed between the upper parts of the two springs 72. The lower side of the third connecting plate 71 is fixed with the wiping rod 73 by screws, and the wiping rod 73 passes through the top of the first connecting frame 43.

[0053] The wiping rod 73 is then disengaged from the V-shaped plate 44, so that the dust and impurities on the V-shaped plate 44 can be cleaned, thereby providing convenience for people to perform the diversion operation of the high-voltage inverter 1.

[0054] Example 5

[0055] On the basis of Example 4, Fig.15 and Fig.16 As shown, it also includes a power mechanism 8, which includes a connecting rod 81, a pull rope 82, a second connecting block 83, a pulley 84, a slider 85 and a slide rail 86. The left and right sides of the third connecting plate 71 are riveted with connecting rods 81, and the two connecting rods 81 are connected with pull ropes 82. The middle parts of the front sides of the two second ventilation plates 52 are fixed with second connecting blocks 83 by screws, and the front sides of the two second connecting blocks 83 are rotatably connected to two pulleys 84.

The second connecting block 83 is in contact with the slider 85, and the first connecting block 65 will contact the slider 85 when it moves upward.

[0056] During the process of cleaning the dust on the surface of the second ventilation plate 52, the first connecting block 65 drives the slider 85 to move upward. Under the sliding cooperation between the slider 85 and the slide rail 86, the pull rope 82 slides upward accordingly. Under the winding action of the pull rope 82 and the two pulleys 84, the pull rope 82 drives the connecting rod 81 to slide downward, so that the dust and impurities on the V-shaped plate 44 can be cleaned more conveniently. After the dust and impurities on the V-shaped plate 44 are cleaned, the first connecting block 65 drives the slider 85 to slide downward, and the pull rope 82 is loosened. Under the elastic force of the spring 72, the third connecting plate 71 drives the connecting rod 81 to reset, so that the dust and impurities remaining on the V-shaped plate 44 can be cleaned more conveniently, thereby providing convenience for people to clean the dust and impurities on the V-shaped plate 44.
