Description

Technical Field

[0001] The invention relates to the technical field of rectifiers, and in particular to a rectifier with a safety protection component. Background Art

[0002] During the use of power equipment, a rectifier is required to meet the needs of the equipment's operation. Because the rectifier is generally installed in a natural environment, impurities and debris in the air can easily enter the interior of the equipment through the ventilation device, so a protective structure needs to be installed at the vent to avoid interference from dust.

[0003] At present, rectifiers generally install a filter on their vents to prevent dust from entering. During long-term use, the filter surface will be attached with a certain amount of dust and mesh debris. Excessive accumulation of dust will reduce its ventilation effect and affect the heat dissipation of the equipment. When cleaning, when there is not much dust on the surface, it is usually cleaned by directly brushing the surface with a brush. This will cause some of the cleaned dust to enter the interior of the equipment with the airflow, causing certain damage. For this reason, we designed a rectifier with a safety protection component.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1 - Fig.11 A rectifier with a safety protection component comprises a rectifier body 1, an exhaust fan 2 is installed at the left end of the rectifier body 1, a vent is respectively opened on the right side of the front and rear ends of the rectifier body 1, a fixing frame 3 is screwed in the vent, a protection net 31 is fixed at the middle opening of the outer side of the fixing frame 3, a dustproof net 32 ​​is installed inside the fixing frame 3, a spacing is left between the protection net 31 and the dustproof net 32 ​​to form an installation bin, a sliding opening is set through the front and rear of the fixing frame 3, and a toggle member 4 is installed in the sliding opening for sliding left and right. A cleaning mechanism 5 for cleaning the dustproof net 32 ​​is installed in the installation bin, and the cleaning mechanism 5 is in contact with the inner surface of the protective net 31 and the outer surface of the dustproof net 32 ​​respectively. The toggle member 4 is connected to the cleaning mechanism 5. A blocking mechanism 6 is rotatably installed on the inner side of the fixed frame 3. The blocking mechanism 6 is located on the inner side of the cleaning mechanism 5, and the inward end of the toggle member 4 is slidably connected to the blocking mechanism 6. An insertion interface is provided at the bottom end of the fixed frame 3, and a collection frame 7 is slidably inserted in the insertion interface, and the interior of the collection frame 7 is connected to the upper side of the fixed frame 3; The toggle member 4 includes a toggle block 41 slidably installed in the sliding opening, the right end of the toggle block 41 is connected to the cleaning mechanism 5, and the toggle block 41 is penetrated by a sleeve interface, and a pull rod 43 is slidably sleeved in the sleeve interface, and a pull ring 431 is provided on the outward side of the pull rod 43; The cleaning mechanism 5 comprises two movable guide rods 56 fixed to the upper and lower ends of the inner wall of the fixed frame 3, and movable guide blocks 55 are respectively sleeved on the movable guide rods 56 for sliding left and right. The sealing mechanism 6 includes a plurality of sealing plates 61 linearly arranged from top to bottom, and a deflection rod 611 is respectively provided at the left and right ends of the sealing plate 61. A connecting guide rod 65 is installed on the upper end of the outward surface of the topmost sealing plate 61, and a deflection shaft plate 66 is slidably sleeved on the connecting guide rod 65 to the left and right. The other end of the deflection shaft plate 66 is rotatably connected to the tail end of the pulling rod 43 through an axle pin.

[0019] The left and right ends of the toggle block 41 are respectively connected to a folding plate 42, and the ends of the two folding plates 42 away from the toggle block 41 are respectively connected to the left and right inner walls of the sliding opening, and the folding plates 42 are a rubber corrugated plate that can be folded. When the toggle block 41 drives the cleaning mechanism 5 to move left and right, the two folding plates 42 on both sides can be unfolded or folded and contracted accordingly, thereby blocking the sliding opening so that it will not be directly exposed to the outside, thereby preventing external impurities and dust from entering.

[0020] A rolling column 44 is fixed above the inner walls on the left and right sides of the fixed frame 3, and a positioning notch 441 is formed through the front and back of the right side of the rolling column 44; A positioning roller 432 is rotatably mounted below the outer ring surface of the pulling rod 43 through an axle pin. The width of the positioning notch 441 is greater than the outer diameter of the positioning roller 432. In the initial state, the positioning roller 432 on the pulling rod 43 slides back and forth and is placed in the positioning notch 441. At this time, the positioning roller 432 can limit the pulling rod 43, so that the pulling rod 43 cannot move left and right, thereby making the cleaning mechanism 5 unable to move and unable to clean the surface of the protective net 31. When the pulling rod 43 is pulled outward to the maximum extent, the positioning roller 432 rolls in contact with the outward surface of the rolling column 44 .

[0021] The left side of the movable guide block 55 is fixed with screws to the toggle block 41 , and a roller shaft 51 is rotatably mounted between the two movable guide blocks 55 via a bearing, and a brush 52 is provided on the outer ring surface of the roller shaft 51 .

[0022] A reset member 57 is installed at the upper and lower ends of the right inner wall of the fixed frame 3, and the upper and lower reset members 57 are connected to two corresponding movable guide blocks 55 respectively; A driving rack 54 is fixed below the inner walls of both sides of the fixed frame 3, a transmission gear 531 is installed at the lower end of the roller shaft 51, and a driving gear 53 is rotatably installed on the upper side of the lower movable guide block 55 through an axle pin. The driving gear 53 is meshed with the transmission gear 531 and the driving rack 54 respectively, and the transmission gear 531 is not meshed with the driving rack 54; The transmission ratio between the transmission gear 531 and the driving gear 53 is greater than 1, so that when the driving gear 53 rotates one circle, the transmission gear 531 will rotate multiple circles, the roller 51 will also rotate multiple circles, and the brush 52 on the roller 51 will also rotate multiple circles. The number of circles of the brush 52 is different from the speed of its translation, so that the surface of the dustproof net 32 ​​can be cleaned; When the toggle block 41 moves left and right, it can drive the upper moving guide block 55 to move left and right, so that the roller 51 installed on the moving guide block 55 moves together. When the roller 51 moves left and right, the driving gear 53 installed on the moving guide block 55 will also move left and right along the driving rack 54, so that the driving gear 53 rotates. The rotating driving gear 53 will cause the transmission gear 531 to rotate. At this time, the roller 51 and the brush 52 rotate together, and the rotation speed of the roller 51 and the brush 52 is greater than the rotation speed of the driving gear 53. There is a misalignment between them, forming a speed difference. The brush 52 can rotate one or more circles when moving a certain distance, increasing its rotation speed and improving the cleaning effect. At this time, the rotating and moving left and right brush 52 will clean the impurities and dust attached to the surface of the dustproof net 32 ​​to prevent it from being blocked, thereby improving the ventilation effect.

[0023] The reset member 57 includes a reset shell 572 fixed to the inner wall of the fixed frame 3, an outlet is opened on the reset shell 572, a tape reel 573 is rotatably installed in the inner cavity of the reset shell 572 through an axle pin, a coil spring 574 is sleeved on the outer ring surface of the tape reel 573, one end of the innermost ring of the coil spring 574 is fixed to the tape reel 573, one end of the outermost ring of the coil spring 574 is connected to a connecting ring belt 571, and the other end of the connecting ring belt 571 is connected to the external moving guide block 55 through the outlet; The structure of the entire reset member 57 is similar to that of a tape measure. When the roller 51 and the movable guide block 55 move to the left under the action of the toggle block 41, the connecting ring belt 571 will be stretched to the left under the action of the movable guide block 55, and the entire coil spring 574 will be unfolded accordingly. At this time, the coil spring 574 has a tendency to return to its original state under its own action. When the toggle block 41 is not subjected to the force moving to the left, the coil spring 574 will rewind to its original shape, and the connecting ring belt 571 will be wound up. During the winding process, the connecting ring belt 571 will pull the moving guide block 55 to move to the right. At this time, the roller shaft 51 and the toggle block 41, the pulling rod 43, and the positioning roller 432 will move to the right together, so that the positioning roller 432 on the pulling rod 43 is placed in the positioning notch 441 again for positioning.

[0024] The baffle plates 61 are rotatably connected to the inner walls of the left and right sides of the fixed frame 3 through the deflection rods 611. The lower part of the outward side of each baffle plate 61 is rotatably connected to a linkage shaft plate 64 through a shaft pin. Two adjacent baffle plates 61 are rotatably connected through the linkage shaft plate 64. When one of the baffle plates 61 is deflected, multiple baffle plates 61 will be deflected synchronously under the action of the linkage shaft plate 64. When the pulling rod 43 is pulled outward, the pulling rod 43 can make the sealing plate 61 deflect with the deflection rod 611 as the axis through the deflection shaft plate 66. At this time, the upper half of the sealing plate 61 deflects outward, and the lower half of the sealing plate 61 deflects inward. The inner and outer side surfaces of the lower halves of two adjacent sealing plates 61 will abut against each other, thereby closing the channels between these sealing plates 61 to ensure that external dust does not enter the rectifier body 1.

[0025] A tension spring 62 is connected to the upper side of the inward side surface of the uppermost sealing plate 61, and the other end of the tension spring 62 is connected to the inner wall of the fixed frame 3. Both ends of the tension spring 62 are provided with hooks. The inward side of the sealing plate 61 and the inner wall of the fixed frame 3 are provided with shaft rods, and both ends of the tension spring 62 are connected to the shaft rods through hooks. Without the action of external force, the tension spring 62 causes the topmost sealing plate 61 to deflect with the deflection rod 611 as the axis, and the multiple sealing plates 61 below will deflect synchronously, with the upper end of the sealing plate 61 deflecting inwards and the lower end of the sealing plate 61 deflecting outwards, so that there is space between two adjacent sealing plates 61 to form a ventilation channel; After the multiple sealing plates 61 are closed, the tension spring 62 is in a stretched state. At this time, the upper part of the sealing plate 61 has a tendency to deflect inward. The sealing plate 61 with a tendency to deflect inward makes the deflection axis plate 66 have a tendency to move inward, which makes the pulling rod 43 have a tendency to move inward. When the pulling rod 43 is at the front side of the positioning notch 441 and is not subjected to outward pulling force, the pulling rod 43 will move inward, and the positioning roller 432 will be snapped into the positioning notch 441.

[0026] In two adjacent sealing baffles 61, the top of the lower sealing baffle 61 is above the bottom end of the adjacent upper sealing baffle 61. After the sealing baffles 61 are deflected, the inner and outer side surfaces of the two adjacent sealing baffles 61 can abut against each other to form a seal. The lower rear half of the interior of the fixed frame 3 is provided with an abutment plate 63, which is in sliding contact with the upper surface of the collecting frame 7. The upper surface of the collecting frame 7 is designed to be open, and a seal is formed between the upper rear half of the collecting frame 7 and the upper part of the abutment plate 63, and the upper front half of the collecting frame 7 is connected to the interior of the fixed frame 3. After the bottom baffle plate 61 is deflected outward, the lower end of the baffle plate 61 can contact with the abutment plate 63 to form a seal. After the top baffle plate 61 is deflected, its top abuts against the top of the inner wall of the fixed frame 3 to form a seal. The dust generated during cleaning will fall through the opening above the collection frame 7 and be collected.

[0027] Working principle: Ventilation holes are arranged on the right sides of the front and rear ends of the rectifier body 1, and a protective net 31 and a dustproof net 32 ​​are installed in the ventilating holes, and an exhaust fan 2 is arranged at the left end of the rectifier body 1. The external airflow enters the rectifier body 1 through the ventilating holes and is discharged through the exhaust fan 2, so as to dissipate heat and cool the internal components. The protective net 31 can block the entry of larger impurities and protect the internal mechanism. The dustproof net 32 ​​can block the entry of dust and debris and protect the internal components. When the dust screen 32 has a lot of dust on its surface and needs to be cleaned, firstly, the pull rod 43 is pulled outward through the pull ring 431. When the pull rod 43 is pulled outward, the uppermost sealing plate 61 will deflect with the deflection rod 611 on its side as the axis. At this time, the upper part of the sealing plate 61 deflects outward, and the lower end of the sealing plate 61 deflects inward. Since the multiple sealing plates 61 are movably connected through the deflection shaft plate 66, the multiple sealing plates 61 will deflect synchronously, and their lower ends will abut against each other, so that the channels between these sealing plates 61 are closed; The pull rod 43 pulled outwards will then cause the positioning roller 432 to disengage from the positioning notch 441, and when the pull rod 43 is pulled outwards to the maximum extent, the positioning roller 432 rolls and contacts with the outward surface of the rolling column 44, and then the pull rod 43 and the toggle block 41 are moved back and forth left and right. When the toggle block 41 moves left and right, it can drive the upper moving guide block 55 to move left and right, so that the roller shaft 51 installed on the moving guide block 55 moves together. When the roller shaft 51 moves left and right, the driving gear 53 installed on the roller shaft 51 will also move left and right along the driving rack 54, so that the driving gear 53 rotates. The rotating driving gear 53 will cause the transmission gear to rotate. At this time, the roller shaft 51 and the brush 52 rotate together, and the rotation speed of the roller shaft 51 and the brush 52 is greater than their movement speed. There is a misalignment between them, and the rotating and moving brush 52 will clean the impurities and dust attached to the surface of the dustproof net 32 ​​to prevent it from being blocked. During the back-and-forth movement of the roller 51 and the brush 52, the sealing plate 61 keeps the entire vent in a closed state, so that the dust swept down will fall down and will not enter the rectifier body 1; When cleaning is completed, the pull ring 431 is released, and when the toggle member 4 is not at its rightmost end, the positioning roller 432 is in rolling contact with the surface of the rolling column 44, and the coil spring 574 has a tendency to return to its original state under its own action; After the pull ring 431 is released, the toggle block 41 is not subjected to the force to move to the left, the coil spring 574 will be rolled back to its original state, the connecting belt 571 will be wound up, and the connecting belt 571 will pull the moving guide block 55 to move to the right during the winding process. At this time, the roller shaft 51, the toggle block 41, the pulling rod 43, and the positioning roller 432 will move to the right together, so that the positioning roller 432 on the pulling rod 43 is located in front of the positioning notch 441; When the positioning roller 432 is in front of the positioning notch 441, since the tension spring 62 is in a stretched state, the upper part of the sealing plate 61 at this time has a tendency to deflect inward, and the sealing plate 61 with a tendency to deflect inward makes the deflection axis plate 66 have a tendency to move inward, which makes the pulling rod 43 have a tendency to be pulled inward, and the positioning roller 432 will move inward and be snapped into the positioning notch 441. At this time, the multiple sealing plates 61 are automatically opened under the action of the tension spring, so that ventilation can be carried out.

[0028] By providing a cleaning mechanism 5 on the front side of the dustproof net 32 ​​and cooperating with the sealing mechanism 6, before the brush 52 in the cleaning mechanism 5 cleans the surface of the dustproof net 32, the multiple sealing plates 61 in the sealing mechanism 6 will be closed, so that the entire vent is in a closed state, and the dust swept down will fall and will not enter the inside of the rectifier body 1. While cleaning the surface of the dustproof net 32, it also prevents dust from entering with the airflow, thereby ensuring the ventilation effect and protecting the internal components; By connecting the cleaning mechanism 5 with the toggle member 4, a positioning structure is provided on the toggle member 4, which cooperates with the reset member 57 in the cleaning mechanism 5, so that the toggle member 4 can return to the initial position and be positioned no matter where it is. The vent must be sealed before the protective net 31 is cleaned, thereby improving safety.
