Embodiment
Below with reference to accompanying drawings embodiments of the invention are described.
The invention provides a kind of protection against the tide and be beneficial to the power distribution cabinet of draining, as shown in Figure 1, this power distribution cabinet comprises cabinet 1 and the top cover 2 that is arranged on cabinet 1 and cabinet door 3.
The bottom of three internal faces of cabinet 1 is respectively equipped with the cabinet drainage channel 13 of horizontal expansion, and the cabinet at cabinet drainage channel 13 place has cabinet osculum 14.In the present embodiment, this cabinet drainage channel all adopts 1/4 pipe to realize in conjunction with wall.As shown in Figure 2,1/4 pipe 12 has two straight flanges and two arc limits, and two ends can arrange block or utilize other structures in cabinet to be blocked at two, the outflow of anti-sealing.As shown in Figure 3, one of them straight flange of 1/4 pipe 12 connects the bottommost of cabinet internal face, 1/4 pipe 12 inside cabinet, 1/4 pipe 12 forms cabinet drainage channel 13 with cabinet internal face, 1/4 pipe 12 and the cabinet of cabinet internal face junction have cabinet osculum 14, thus the water being incorporated into cabinet drainage channel 13 is discharged outside cabinet.
The internal face of top cover 2 is clinoplain, angle of inclination is 2 ° ~ 5 ° is good, after the condensation vapor be gathered on top cover becomes the globule, under the guide functions on inclined plane, flow to lower and then flow to wall, reduce the water droplet possibility of directly dripping from top cover, avoid water droplet to drip the security threat caused the electric equipment in power distribution cabinet as far as possible.
Cabinet 1 inside is provided with two fans 15, and these two fans 15 are arranged on relative two sides, cabinet 1 rear portion, and distribute one on the other, can form convection current wind like this at cabinet rear portion, thus heat radiation and dehumidifying.The dehumidifying work of cabinet front portion is responsible for by the drier placed in cabinet door boss described below.
Cabinet can there be a fan or many fan cabinet doors.In the present embodiment, often fan the one group of reinforcement 34 being provided with inside cabinet door 3 and arranging in cross, reinforcement 34 extends to the border of cabinet door 3 along four direction.The region not arranging reinforcement in cabinet door arranges boss 35, and boss 35 diagonally arranges on cabinet door.Boss material identical with cabinet door, is fixed on cabinet door by welding manner.Boss 35 is hollow-core construction, and it takes into account the function of strengthening and laying drier.The boss 35 of the reinforcement 34 that cross of the present invention is arranged and diagonal row defines " rice " font and strengthens structure, thus ensures the stiffening effect of all angles.
Boss 35 of the present invention is semi-cylindrical, as shown in Fig. 4 (a) He Fig. 4 (b), specifically comprises body 351 and capping 352.Body 351 adopts the semicolumn housing spiral-lock of hollow to be formed on cabinet door, the opening up opening of semicircle of semicolumn shell one end, the semicircle opening of the other end installs capping 352 to be opened/closed, as shown in the figure, capping 352 is arranged on bottom body 351 by rotating shaft, capping connects hasp by rotating shaft, and body 351 is provided with projection, and hasp and protruding cooperatively interacting realize the locking of capping and body.
Drier in bulk is loaded in body 351 by opening upward, when drier changed by needs, capping 352 can be opened, make drier naturally drop out, after covering capping, then load new drier from open top.In order to increase the contact area of drier and air further, body 351 first half offers the through hole for moisture absorption, and only the first half offers through hole is to prevent drier from spilling.In the present embodiment, semi-cylindrical boss is easily processed, and uses drier moisture sorption effect in bulk better.
In order to lock cabinet door position behind the door pulling open cabinet, the top of often fanning cabinet door 3 is provided with the air pressure pull bar 36 is connected with cabinet, and this pull bar of the present invention is arranged on cabinet door top, is more convenient for operating.
Four limits of often fanning cabinet door 3 have inside flanging, are provided with the right-angled trapezium sealing strip 32 as shown in Fig. 5 (a) in flanging, and as shown in Fig. 5 (b), the minor face of right-angled trapezium sealing strip 32 embeds in cabinet door flanging, and long limit is stayed outside flanging.After embedding flanging, part sealing strip is still retained in outside flanging with outstanding form, and outstanding sealing strip can reach better sealing effectiveness.
Cabinet door 3 inwall arranges information kit 31.Due to cabinet door having reinforcement and boss, the clear area not having one piece of area larger arranges metal hold-down bar, therefore this programme adopts mounting means more flexibly and the information kit 31 of convenient nonwoven fabrics material of replacing, information kit 31 is fixed on cabinet door 3 by velcro, and velcro is fixed on cabinet door 3 by the mode pasted.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
