[0002] Air-cooled reactors with a series structure are important components in power systems and electronic circuits. Their design and application are intended to optimize circuit performance and ensure stable operation of equipment. Air-cooled reactors with a series structure are composed of multiple inductors or capacitors connected in series to form a circuit path connected in sequence. This structure enables each reactor to generate impedance to signals or currents, thereby affecting the performance of the entire circuit.

[0003] Chinese patent announcement number CN220984298U discloses an air-cooled series reactor, which achieves a heat dissipation effect on the iron core by arranging a heat sink on the reactor body. At the same time, an axial flow fan and a normally open temperature switch are arranged. When the operating temperature of the reactor body exceeds the set value, the temperature switch is closed to connect the power of the axial flow fan, and the axial flow fan is started to perform heat dissipation, thereby reducing the operating temperature of the reactor to below the set temperature value, thereby ensuring the parameter stability of the reactor.

[0004] However, in actual use, the above structure uses a radiator to dissipate heat for the series inductor. When the radiator is used for a long time, the filter on the radiator will be attached due to dust or impurities in the air. The accumulated dust and impurities will directly affect the heat dissipation effect of the radiator, thereby reducing the heat dissipation effect of the radiator. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figure 1-Figure 6As shown, a series-type air-cooled reactor comprises a base 1, a series-type reactor 2 arranged on the base 1, a mounting frame 4 arranged on the series-type reactor 2 for mounting an air-cooled chassis 3, a filter screen 5 arranged on the air-cooled chassis 3 for filtering dust and impurities in the air, and a vibration cleaning mechanism 6 for automatically cleaning dust on the filter screen 5 to ensure continuous ventilation and heat dissipation of the series-type reactor 2, the vibration cleaning mechanism 6 comprising a cleaning scraper 61, a first contact plate 611 arranged on the cleaning scraper 61, and a contact ball 51 arranged on the filter screen 5 for contacting the first contact plate 611, and a linkage driving mechanism for driving the cleaning scraper 61 to reciprocate in a horizontal straight line direction. Structure 7, the air-cooled chassis 3 is provided with an avoidance opening 31 for air circulation, the mounting frame 4 is provided with an installation groove 41 for installing the air-cooled chassis 3, and the mounting frame 4 is also provided with a pair of mounting holes corresponding to the positions on the air-cooled chassis 3, and a threaded locking rod 42 threadedly connected in the mounting holes. In the installed state, a space for air circulation is reserved between the air-cooled chassis 3 and the mounting frame 4, so that the air in the air-cooled chassis 3 can pass through the avoidance opening 31 to achieve a good heat dissipation effect on the series inductor 2. The air-cooled chassis 3 is also provided with a plurality of cooling pipes 32, and the other end of the cooling pipes 32 is close to the series inductor 2, so as to facilitate the heat dissipation of the outside of the series inductor 2 and improve the heat dissipation effect of the series inductor 2.

[0030] When the series reactor 2 needs to be cooled, the air-cooled chassis 3 is first installed through the installation groove 41 provided on the installation frame 4, and then the threaded locking rod 42 is threadedly connected to the installation hole. At this time, the quick installation of the air-cooled chassis 3 is completed. After installation, the rotation driver 71 is set in the air-cooled chassis 3 to start, and the blades set on the rotating rod 72 are driven to rotate. When the blades rotate, air can be driven to enter through the detachable filter 5 on the air-cooled chassis 3. At this time, the series reactor 2 can be cooled. In the process of rotation of the rotating rod 72, the rotation force of the transmission rod 75 can be transmitted through the external synchronous belt 74. When the transmission rod 75 rotates, the swing block 76 can be driven to reciprocate the sliding rod 77 in a horizontal straight line. When the sliding rod 77 slides, the cleaning scraper 61 can be driven to timely connect the dust on the filter 5. When the cleaning scraper 61 reciprocates in the horizontal straight line direction, it can drive the first contact plate 611 fixedly connected thereto to intermittently contact with the contact ball 51 set on the filter 5. When in contact, the filter 5 and the limiting docking rod 512 can be caused to descend in the vertical direction along the docking plate 511 with a clearance fit in the vertical direction, and the first telescopic spring 513 is compressed in this process. When the first contact plate 611 is not in contact with the contact ball 51, the compressed first telescopic spring 513 is released, and the limiting docking rod 512 and the filter 5 are lifted up in the vertical direction along the docking plate 511, so that the cleaning scraper 61 can continuously clean the filter 5 by contact vibration, so that the filter 5 is always kept clean, avoiding direct scratching to damage the surface of the filter 5, thereby extending the service life of the filter, and will not affect the heat dissipation effect of the series inductor 2.

[0031] See also Figure 5-Figure 7 As shown, the linkage drive mechanism 7 includes a rotary driver 71 and a rotating rod 72; the rotary driver 71 is arranged in the air-cooled chassis 3; the rotating rod 72 is arranged at the output end of the rotary driver 71 through a coupling, and a blade coaxially fixed with the rotating rod 72 is arranged in the air-cooled chassis 3. A clearance groove 33 for installing the filter 5 is opened on the air-cooled chassis 3, and the filter 5 and the limiting docking rod 512 can be directly placed on the clearance groove 33 and the docking plate 511 for quick installation.

[0032] When the series inductor 2 needs to be cooled, a rotary driver 71 is set in the air-cooled chassis 3 and started, thereby driving the rotating rod 72 to rotate. When the rotating rod 72 rotates, the blades can be driven to rotate synchronously. When the blades rotate, air can enter through the filter 5, and the series inductor 2 can be cooled.

[0033] See also Figure 5-Figure 7As shown, the linkage drive mechanism 7 further includes a connecting plate 73 and a synchronous belt 74 ; the connecting plate 73 is arranged on the air-cooled chassis 3 ; and the synchronous belt 74 is sleeved on the rotating rod 72 .

[0034] When the rotating rod 72 rotates, the rotational force can be transmitted through the synchronous belt 74 .

[0035] See also Figure 6 As shown, the linkage drive mechanism 7 also includes a transmission rod 75; the transmission rod 75 is rotatably set on the connecting plate 73 and close to one side of the rotating rod 72. The transmission rod 75 is installed on the connecting plate 73 through a bearing, and the synchronous belt 74 is respectively mounted on the rotating rod 72 and the transmission rod 75.

[0036] When the synchronous belt 74 performs rotational transmission, the transmission rod 75 can be driven to perform rotational movement along the connecting plate 73 installed with the bearing.

[0037] See also Figure 7-Figure 9 As shown, the linkage drive mechanism 7 also includes a swing block 76 and a sliding rod 77; the swing block 76 is arranged on the transmission rod 75 and is coaxially fixed with the transmission rod 75; the sliding rod 77 is arranged on the air-cooled chassis 3 in the horizontal linear sliding direction, and the air-cooled chassis 3 is provided with a limiting block 34 for limiting the sliding of the sliding rod 77 in the horizontal linear direction, and a pair of return springs 771 are sleeved on the sliding rod 77, and the two ends of the return spring 771 are respectively fixed to the ends of the sliding rod 77 and the limiting block 34, and a touch block 761 that intermittently contacts the sliding rod 77 is provided on the swing block 76, and the sliding rod 77 is fixedly connected to the cleaning scraper 61, and the cleaning scraper 61 is located above the filter screen 5, and the cleaning scraper 61 can be detachably connected to the sliding rod 77 through a locking member, and the cleaning scraper 61 can be a sponge or a material with a good cleaning effect.

[0038] When the transmission rod 75 continues to rotate, it can drive the swing block 76 fixed coaxially therewith to perform synchronous rotational movement. When the swing block 76 rotates, it can contact the sliding rod 77 through the touch block 761 fixedly connected thereto. When the sliding rod 77 and the touch block 761 contact each other, the sliding rod 77 can be driven to slide in a horizontal straight line direction along the limiting block 34. In this process, the sliding of the sliding rod 77 can drive the cleaning scraper 61 detachably connected thereto to clean the dust on the filter screen 5 in a horizontal straight line direction. When the touch block 761 does not contact the sliding rod 77, a reset spring 771 is arranged outside the sliding rod 77 to drive the sliding sliding rod 77 to reset and cause the sliding rod 77 to return to the initial position. Through this intermittent contact and intermittent resetting of the cleaning scraper 61, intermittent contact reciprocating cleaning of the dust on the filter screen 5 is achieved. On the one hand, it reduces the time for manual supervision and cleaning, and on the other hand, it also indirectly improves the heat dissipation effect of the series inductor 2.

[0039] See also Fig. 9 As shown, the linkage drive mechanism 7 further includes a contact block 78 ; the contact block 78 is disposed on the sliding rod 77 and has a plurality of contact blocks 78 , the contact block 78 is made of rubber material, and the contact block 78 can contact with the touch block 761 .

[0040] When the swing block 76 rotates, it can drive the touch block 761 fixed thereto to contact with the contact block 78 set on the sliding rod 77, and engage during the contact process, thereby achieving intermittent contact with the sliding rod 77 through the engaging relationship, until the swing block 76 continues to rotate, so that the contact block 78 can be driven out of contact with the touch block 761. At this time, the sliding rod 77 can be pushed by the reset spring 771 to slide for reset.
