Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A waterproof frequency converter comprises a shell 2, wherein the front end of the shell 2 is hermetically connected with a cover 1, a water retaining groove 4 is jointly covered above the shell 2 and the cover 1, and waterproof mechanisms 3 are symmetrically arranged on two sides of the shell 2 and the cover 1;

the waterproof mechanisms 3 are positioned on two sides of the shell 2 and the cover 1, can prevent water from being formed in a side gap where the shell 2 is connected with the cover 1, and effectively prevents rainwater and the like from permeating into the shell from the gap to damage internal parts; as shown in fig. 5, the waterproof mechanism 3 includes an inner side turnover plate 31, an outer side turnover plate 32, and a sealing strip 33, as shown in fig. 2, the inner side turnover plate 31 is turned over to the rear side and is fixedly connected with the cover 1, as shown in fig. 3, the outer side turnover plate 32 is turned over to the front side and is fixedly connected with the casing 2, the inner side turnover plate 31 is inserted into the outer side turnover plate 32, the sealing strip 33 is hermetically plugged into the inner side of the inner side turnover plate 31, and the sealing strip 33 is sealed and blocked at the side gap where the casing 2 is connected with the cover 1; firstly, the outer side turnover plate and the inner side turnover plate are used for first shielding at the outermost side to prevent rainwater from splashing into the frequency converter from the side, and secondly, the sealing strip 33 is used for further sealing a cavity formed between the inner side turnover plate 31 and the shell and the cover to effectively prevent rainwater from permeating. In addition, in order to ensure that the inner side flap 31 does not sway left and right in the outer side flap 32, as shown in fig. 5, an extension limiting plate 34 fixed on the inner side flap 31 is longitudinally arranged at one end of the inner side flap 31, and a limiting groove 35 matched with the extension limiting plate 34 is formed in the outer side flap 32.

When waterproofing mechanism 3 carries out waterproof sheltering from, casing 2 and cover 1 sealing connection specifically have: as shown in fig. 2, slot 22 has been seted up along the preceding terminal surface of lateral wall to casing 2, as shown in fig. 2, set firmly on the rear end face of cover 1 with the cutting 11 of slot 22 looks block, through the matching effect of slot and cutting, can make casing and cover fix a position the matching fast, can also shelter from as the second way, further prevent the infiltration of rainwater. Meanwhile, a sealing ring 23 fixed on the side wall of the casing 2 is further arranged in the casing 2, and the sealing ring 23 extends out of the casing 2 from the front end opening of the casing 2, so that when the casing 2 is connected with the cover 1, the sealing ring 23 is inserted into the cover, and the sealing ring 23 is used for sealing and shielding the inner side gap at the joint of the casing 2 and the cover 1.

From this, through waterproof mechanism 3, cutting 11 and slot 22, 23 three sealed structures of sheltering from, the abundant gap shutoff that forms casing 2 and fuselage side can prevent effectively that the rainwater from infiltrating in the casing, avoids the inside spare part of converter to suffer the erosion of rainwater, has both improved the work security of converter, has still lengthened the life of converter.

Generally, a large amount of heat is generated during the operation of the frequency converter, in order to ensure the normal heat dissipation of the frequency converter, heat dissipation holes are formed in the top end of a shell of the frequency converter, as shown in fig. 1, top heat dissipation holes 21 are formed in the top of a shell 2, and rainwater is easy to splash into the shell 2 due to the arrangement of the top heat dissipation holes 21, so that a water retaining groove 4 is jointly covered above the shell 2 and a cover 1, as shown in fig. 4, the water retaining groove 4 is provided with three side walls, the three side walls extend to the side edges of the shell 2 and the cover 1, the water retaining groove 4 is fixedly connected with the shell 2 through a rear side wall, and; the water blocking groove 4 blocks the top heat radiation hole 21 above the housing 2 and blocks the top end of the waterproof mechanism 3, thereby achieving waterproofing from above through the water blocking groove 4. To manger plate 4, water storage recess 41 has been seted up at its top, catch the rainwater by water storage recess 41, compare in traditional manger plate, the rainwater drips can splash everywhere on the manger plate, the rainwater that can make splashing everywhere to a certain extent splashes and falls to casing department, therefore, the design has water storage recess 41 can avoid this phenomenon to take place, by the drain pipe of water storage recess 41 intercommunication extension design, drain pipe 42 is located one side of manger plate 4 and extends to the outside, and drain pipe 42's drainage opening is downward, the direct water drainage that will collect through the drain pipe. Meanwhile, in order to facilitate the water in the water storage groove 41 to be discharged out smoothly, the rear end of the water storage groove 41 is high, the front end is low, and the drain pipe 42 is connected to the front half part of the water storage groove 41.

In addition, for promoting this waterproof type converter's convenience of use, casing 2 and cover 1 alternative install jointly on base 5, have seted up the mounting groove on base 5, and casing 2 and cover 1 insert the mounting groove in and connect base 5 through bolt fastening's mode detachably. The design of base 5 makes things convenient for the direct use of placing of converter.

The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
