Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment:
Embodiment 1
Fig. 1-5, a kind of shock-absorbing type electric power cabinet with self-cleaning function, including cabinet body 1 are please referred to, is connected to and is equipped at the top of cabinet body 1
Cover 3 offers air outlet 4 at the top of cover 3, the aerofoil fan 2 by the driving rotation of motor 5,1 side of cabinet body is equipped in cover 3
Wall is uniformly provided with several air inlets 8 disposed in parallel, is fixed with the coaming plate 7 for being disposed around 8 surrounding of air inlet on cabinet body 1, encloses
Cleaning mechanism is equipped in plate 7, cleaning mechanism includes the brush plate 12 being bonded with 1 side wall of cabinet body, is equipped with and is used at the top of the cabinet body 1
The transmission mechanism of 12 traverse motion of brush plate is driven, 1 bottom of cabinet body is connected with cushion socket 9 by damping.
For installing power equipment inside cabinet body 1, the motor 5 being arranged on cover 3 drives aerofoil fan 2, axis stream
The rotation of fan 2, which is realized, is lifted up the relatively thermal current inside cabinet body 1, final to realize that cabinet body 1 is discharged by air outlet 4 in hot-air,
And the lower air of 1 external temperature of cabinet body is entered cabinet body 1 and is cooled down to power equipment by air inlet 8 at this time.
Due to containing more dust in outside air, for a long time in use, dust is easily accumulated on 1 side wall of cabinet body and
The blocking for causing air inlet 8 directly contributes the unsmooth of 1 inner air and outer air convection current of cabinet body, and the cooling effect inside cabinet body 1 is poor, is
This, the present apparatus is provided with cleaning mechanism, further includes the threaded rod 13 rotated by transmission mechanism driving, thread bush on threaded rod 13
It is connected to thread bush block 14, hinge bar II15 is symmetrically hinged on thread bush block 14, hinge bar II15 is far from 14 one end of thread bush block
Hinged with brush plate 12,1 side wall of cabinet body is fixed with fixed block 10, and hinge bar I11 is hinged between fixed block 10 and brush plate 12.
By above-mentioned setting, when threaded rod 13 rotates, thread bush block 14 is moved along threaded rod 13, at this time hinge bar
II15 and hinge bar I11 realizes lateral push-and-pull to brush plate 12, i.e., brush plate 12 contact while 1 lateral wall of cabinet body it is opposite into
8 transverse shifting of air port, and then realize that the cleaning to air inlet 8 acts on, it avoids converging dust on air inlet 8, ensure that in cabinet body 1
The unobstructed convection current of outer air, greatly improves cooling effect.
Embodiment 2
Further to promote brush plate 12 to the cleaning efficiency of brush plate 12, on the basis of embodiment 1, in addition, transmission mechanism
Including the transmission gear I20 and transmission gear II21 being coaxially set on threaded rod 13, transmission gear I20 and transmission gear II21
Upper engagement respectively is connected with teeth and passes through towards opposite half gear I16 and half gear II18, half gear I16 and half gear II18
Reversing mechanism rotates backward connection, and transmission case 24 is covered on reversing mechanism, and reversing mechanism includes coaxially solid with half gear II18
Fixed bevel gear II22 and with the co-axially fixed bevel gear III23 of half gear I16, between bevel gear II22 and bevel gear III23
Engagement is connected with bevel gear I17.
By above-mentioned setting, when half gear II18 rotation, bevel gear II22 synchronizes rotation, and bevel gear II22 passes through
Bevel gear I17 realizes the rotation of bevel gear III23, and then half gear I16 and bevel gear III23 is driven to rotate in same direction, due to cone
Gear III23 is turned to bevel gear III23 on the contrary, then half gear II18 is opposite with half gear I16 steering.
When half gear II18, which is rotated clockwise, to be engaged with transmission gear II21, transmission gear II21 rotates counterclockwise,
During this, half gear I16 is rotated counterclockwise and is not engaged with transmission gear I20, when half gear II18 and transmission gear II21 points
From when, half gear I16 engages connection with transmission gear I20, and transmission gear I20 realization rotates clockwise, and repeatedly, realizes
Transmission gear II21 it is synchronous with transmission gear I20 it is suitable, be alternately rotated counterclockwise, i.e., threaded rod 13 is suitable, is alternately rotated counterclockwise, real
The traverse motion for having showed brush plate 12 is played to the efficient dust cleaning effect of air inlet 8.
In addition, the output shaft in motor 5 is sequentially connected by pulley mechanism 6 and half gear II18, motor 5 is in drive shaft
While flow fan 2 rotates, output shaft drives threaded rod 13 to rotate by pulley mechanism 6, realizes the transverse direction of brush plate 12
Air inlet 8 is cleared up in movement, and the deashing of air inlet 8 is realized in the rotation of aerofoil fan 2, ensure that the unimpeded of air inlet 8, has
Effect improves the heat dissipation effect of cabinet body 1, and above structure is used as unique power source by motor 5, and the energy is greatly saved.
Due in the power equipment course of work inside cabinet body 1, it will usually biggish vibration is generated, to guarantee that electric power is set
Standby steady running, is also provided with damping comprising the guide rod 26 being horizontally fixed in cushion socket 9, the interior sliding of guide rod 26
Be arranged there are two symmetrically arranged sliding block 27, be hinged with support rod 25 between sliding block 27 and cabinet body 1, sliding block 27 and cushion socket 9 it
Between be fixed with the damping spring 28 being set on guide rod 26, sleeve 29 is vertically fixed on cushion socket 9, is slidably installed in sleeve 29
There is the guide post 19 for being fixed on 1 bottom of cabinet body.
The sliding block 27 of setting can be slided along guide rod 26, and support rod 25 is for being supported cabinet body 1, and damping bullet
Spring 28 occurs elastic deformation and plays the role of to the good elastic shock attenuation of cabinet body 1, while the guide post 19 of 1 bottom of cabinet body is produced in cabinet body 1
It can be slided along sleeve 29 when raw vibration, guarantee longitudinal displacement without deviating, the power equipment inside cabinet body 1 is steadily transported
Row.
In conclusion the present invention has to the 1 good result of ventilating heat dissipation in inside of cabinet body, pass through the cleaning mechanism energy of setting
The traverse motion for realizing brush plate 12 is played and is cleaned to 8 dust of air inlet on 1 side wall of cabinet body, avoids in external dust
It results in blockage to air inlet 8, guarantees that the air-flow of external lower temperature can quickly enter inside cabinet body 1, realize cabinet body 1
Internal cooling and heat dissipation rapidly and efficiently, while the damping being arranged can carry out good cushioning buffer effect to cabinet body 1, guarantee
The normal steady running of 1 internal power equipment component of cabinet body.
