DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1 and Figure 2As shown, a dust-proof and heat-dissipating power transmission and transformation engineering wiring device comprises a body 1, a dust-proof plate 2 arranged on the body 1 for shielding dust, a heat dissipation bellows 3 for ventilating and dissipating the body 1, a filter 4 detachably arranged on the body 1 for intercepting dust in the air, and a linkage cleaning mechanism 5 arranged on the heat dissipation bellows 3 and used for automatically cleaning dust on the filter 4, the linkage cleaning mechanism 5 comprises a reciprocating cleaning gear ring 51 and a driving mechanism 6 for driving the reciprocating cleaning gear ring 51 to slide in a horizontal straight line direction, the power transmission and transformation engineering wiring device also comprises an auxiliary positioning mechanism 7 for assisting the connection between the wires, a connection block 11 for placing the wires is arranged in the body 1, and a pair of docking ports 12 for inserting the wires are opened on the body 1.

[0029] When it is necessary to dissipate heat for the wires being connected on the wiring block 11 placed in the body 1, first, the fan 61 set in the heat dissipation wind box 3 is started, and then the first transmission rod 62 is driven to rotate. When the first transmission rod 62 rotates, the fan blade 621 can be driven to rotate. At this time, external air can enter the body 1 through the filter screen 4 and dissipate heat in the body 1. When it is necessary to clean the dust accumulated on the filter screen 4, the first transmission rod 62 can transmit the rotation force of the first transmission rod 62 to the second transmission belt 63 when the first transmission rod 62 rotates. The second transmission rod 64 rotates, and when the second transmission rod 64 rotates, the semi-sector gear 65 can be driven to rotate synchronously. Since the semi-sector gear 65 is meshed with the reciprocating cleaning gear ring 51, the semi-sector gear 65 can drive the meshing reciprocating cleaning gear ring 51 to slide smoothly along the connecting plate when rotating. When the reciprocating gear ring slides, the rolling roller 66 can be driven to contact the surface of the filter screen 4, so as to automatically clean the dust on the filter screen 4 without manual supervision and cleaning, so as to prevent dust clogging and affect the heat dissipation effect in the body 1 and cause heat accumulation.

[0030] See also Figure 3-Figure 7 As shown, the driving mechanism 6 includes a fan 61 and a first transmission rod 62; the fan 61 is arranged in the heat dissipation bellows 3; the input end of the first transmission rod 62 is connected to the output end of the fan 61 through a coupling, and a fan blade 621 coaxially fixed with the first transmission rod 62 is arranged in the heat dissipation bellows 3.

[0031] When the body 1 needs to be cooled, the fan 61 in the cooling bellows 3 is started, thereby driving the first transmission rod 62 to rotate.

[0032] See also Figure 7-Figure 9 As shown, the driving mechanism 6 also includes a transmission belt 63 and a second transmission rod 64; the transmission belt 63 is sleeved on the first transmission rod 62; the second transmission rod 64 is rotatably set on the heat dissipation bellows 3 and close to the first transmission rod 62, and the transmission belt 63 is respectively sleeved on the first transmission rod 62 and the second transmission rod 64 to realize the transmission of the rotating power source.

[0033] When the first transmission rod 62 rotates, the rotational force can be transmitted to the second transmission rod 64 through the externally sleeved transmission belt 63, and when the second transmission rod 64 rotates, the second transmission rod 64 can be driven to rotate synchronously.

[0034] See also Figure 3-Figure 4 As shown, the driving mechanism 6 also includes a half-sector gear 65 and a rolling roller 66; the half-sector gear 65 is arranged on the second transmission rod 64 and is coaxially fixed with the second transmission rod 64; the rolling roller 66 is rotatably arranged on the reciprocating cleaning gear ring 51 and is located above the filter screen 4, the half-sector gear 65 is meshed with the reciprocating cleaning gear ring 51, and a pair of mounting plates 651 are provided on the body 1 to be respectively located on both sides of the reciprocating cleaning gear ring 51, and a linear travel groove 652 is opened on the mounting plate 651 for the reciprocating cleaning gear ring 51 to slide in a horizontal linear direction.

[0035] When the second transmission rod 64 rotates, it can drive the coaxially fixed half-sector gear 65 to rotate synchronously. When the half-sector gear 65 rotates, the meshing reciprocating cleaning gear ring 51 can make a stable linear horizontal sliding along the linear travel groove 652 opened on the mounting plate 651. During this process, the rolling roller 66 rotatably arranged under the reciprocating cleaning gear ring 51 contacts the filter screen 4. When in contact, the dust accumulated or attached on the filter screen 4 can be automatically cleaned, so that the dust on the filter screen 4 can be cleaned synchronously when the fan 61 rotates. On the one hand, there is no need for manual supervision and cleaning. On the other hand, it can also prevent the filter screen 4 from affecting the ventilation and heat dissipation effect in the body 1 due to dust accumulation or adhesion.

[0036] See also Figure 3-Figure 8 As shown, the auxiliary positioning mechanism 7 includes a limiting plate 71 and a first squeezing roller 72; the limiting plate 71 is arranged on the machine body 1 and has two pairs; the first squeezing roller 72 is rotatably arranged on the limiting plate 71, and a limiting groove 711 arranged in a vertical direction is opened on the limiting plate 71, and a mounting block for mounting the first squeezing roller 72 is provided on the limiting plate 71.

[0037] When it is necessary to introduce the wire into the machine body 1 for wiring, the wire is first inserted from the docking port 12 until the wire is located below the first squeezing roller 72 and the limiting roller 74 .

[0038] See also Figure 8As shown, the auxiliary positioning mechanism 7 also includes a second squeezing roller 73, a limiting roller 74 and a lifting cylinder 733; the second squeezing roller 73 is rotatably arranged on the limiting plate 71; the limiting roller 74 is arranged on the first squeezing roller 72 and is coaxially fixed with the second squeezing roller 73; the lifting cylinder 733 is arranged on the machine body 1 and is located below the second squeezing roller 73 and the limiting roller 74, the input end of the second squeezing roller 73 is connected to the rotation driver 731 through a coupling, and a slide groove 732 is provided on the limiting plate 71 for the rotation driver 731 to be installed and slide in the vertical direction, and the protruding end of the lifting cylinder 733 is provided with a connecting support plate 734 connected to the bearing between the second squeezing roller 73.

[0039] When the wire is introduced between the first squeezing roller 72 and the limiting roller 74, the rotary driver 731 is started, thereby driving the second squeezing roller 73 coaxially connected thereto to rotate synchronously. When the second squeezing roller 73 rotates, it can drive the coaxially fixed limiting roller 74 to convey the wire. Since the limiting roller 74 is in the shape of two-sided draft and the middle is lower, the wire can be restricted by the limiting roller 74 and is always in a state of parallel and stable conveying. When the diameter of the wire is different and the spacing between the limiting roller 74 and the first squeezing roller 72 needs to be adjusted, it is only necessary to start the lifting cylinder 733. When working, the lifting cylinder 733 can connect the supporting plate 734 to make the second squeezing roller 73 rise stably in the vertical direction along the limiting groove 711 opened on the limiting plate 71, reduce the spacing between the first squeezing roller 72, and achieve the spacing adjustment of the first squeezing roller 72 and the limiting roller 74 bracket distance, which is convenient for auxiliary traction of wires of different diameters and improves the applicability of the device.
