Description

Generator casing convenient to assembly

Technical Field

The utility model belongs to the technical field of the generator, specifically speaking especially relates to a generator housing convenient to assembly.

Background

The generator is widely used and used in various fields. The generator can produce a large amount of heats at the operation in-process, traditional generator housing is closed shell, the generator passes through electric current at working process stator winding and produces the electromagnetic field, although winding resistance is very little, but can know by the joule law, through electric current production heat in the winding, the electric current is big more, the heat that produces along with the increase of time is more, if the heat does not in time distribute away, will arouse the winding and last high temperature, make the motor appear the excess temperature protection, make the motor can not normally work, can burn out winding insulating varnish when serious, make the winding short circuit. The heat radiation performance of the generator is closely related to the operating efficiency.

The existing generator shell is not easy to disassemble and assemble, has poor heat dissipation effect and is inconvenient, and the invention provides a generator shell convenient to assemble.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a generator housing convenient to assembly has increased positioner for the dismantlement and the equipment of shell and top cap are more accurate convenient, have better heat dispersion simultaneously, can improve generator housing's life.

The purpose of the utility model can be realized by the following technical scheme: a generator shell convenient to assemble comprises a generator body, a generator shell and a top cover, wherein a positioning mechanism is fixedly connected below the top cover and comprises a positioning column and a convex block, and the top of the generator shell is provided with a positioning groove matched with the positioning mechanism;

grooves are formed in the side faces of the top cover and the generator shell, and fixing blocks are connected in the grooves in a pin mode;

the outside rigid coupling of generator body has radiating fin, the rigid coupling has a plurality of cooling tubes on the radiating fin, the other end of cooling tube stretches out the outside of generator shell, still open a plurality of through-holes on the generator shell, the outside of through-hole is provided with the filter screen.

Furthermore, the bump is an elastically deformable bump.

Furthermore, the diameter of the filter screen is larger than that of the through hole.

Furthermore, pin holes are formed in the outer side of the groove and the fixing block.

Furthermore, the radiating pipe and the through hole are arranged at intervals.

The utility model has the advantages that:

1. the utility model is provided with the positioning mechanism, so that the top cover is more accurate when fixedly connected with the generator shell, the top cover and the generator shell can be relatively fixed without the help of others, and then the generator shell and the top cover are further fixed through the fixed block and the pin;

2. the utility model discloses be provided with radiating fin, cooling tube and through-hole interval set up, can accelerate the inside air flow of generator housing, with inside steam effluvium, heat dispersion is better, has improved generator housing's life.

Drawings

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of the explosion state of the present invention;

fig. 2 is a schematic view of the mechanism in use state of the present invention.

In the figure: 1. a generator body; 2. a generator housing; 3. a top cover;

4. a positioning mechanism; 41. a positioning column; 42. a bump;

5. positioning a groove; 6. a groove; 7. a fixed block; 8. a heat dissipating fin; 9. a radiating pipe; 10. a through hole; 11. a filter screen; 12. a pin hole.

Detailed Description

The present invention is further explained with reference to the accompanying drawings, as shown in fig. 1 to 2 of the drawings of the specification, a generator housing convenient to assemble includes a generator body 1, a generator housing 2 and a top cover 3, a positioning mechanism 4 is fixedly connected below the top cover 3, the positioning mechanism 4 includes a positioning column 41 and a bump 42, and a positioning groove 5 adapted to the positioning mechanism 4 is opened at the top of the generator housing 2;

grooves 6 are formed in the side faces of the top cover 3 and the generator shell 2, and fixing blocks 7 are connected to the grooves 6 in a pin mode;

the outside rigid coupling of generator body 1 has radiating fin 8, the rigid coupling has a plurality of cooling tubes 9 on radiating fin 8, the outside of generator housing 2 is stretched out to the other end of cooling tube 9, still open a plurality of through-holes 10 on generator housing 2, the outside of through-hole 10 is provided with filter screen 11.

Further, the bump 42 is an elastically deformable bump.

Further, the diameter of the filter screen 11 is larger than that of the through hole 10.

Further, pin holes 12 are formed in the outer side of the groove 6 and the fixing block 7.

Further, the radiating pipe 9 and the through hole 10 are spaced apart.

The use principle is as follows:

the utility model discloses during the installation, insert positioning mechanism 4 constant head tank 5, because lug 42 is elastically deformable's lug, both can stretch into constant head tank 5 and resume original form, positioning mechanism 4 just blocks into constant head tank 5 in, more accurate when just making top cap 3 and generator housing 2 rigid coupling, do not need others to help just can be with top cap 3 and generator housing 2 relatively fixed earlier. Then place fixed block 7 in the recess 6, all be provided with pinhole 12 on the outside of recess 6 and the fixed block 7, fixed block 7 and pin are further fixed to generator housing 2 and top cap 3. When the generator is disassembled, the generator shell 2 and the top cover 3 can be conveniently separated only by reverse operation.

The outside rigid coupling of generator body 1 has radiating fin 8, and the rigid coupling has a plurality of cooling tubes 9 on radiating fin 8, and the other end of cooling tube 9 stretches out the outside of generator housing 2, has still opened a plurality of through-holes 10 on the generator housing 2, and the outside of through-hole 10 is provided with filter screen 11. The radiating pipe 9 and the through hole 10 are spaced apart. The diameter of filter screen 11 is greater than the diameter of through-hole 10, can carry out certain filtration to the air, places the dust and gets into in a large number the generator housing. The arrangement of the radiating fins 8, the radiating pipes 9 and the through holes 10 can accelerate the air flow inside the generator housing, the inside hot air is diffused, the radiating performance is better, and the service life of the generator housing is prolonged.

The foregoing is merely exemplary and illustrative of the structure of the invention, and various modifications, additions and substitutions as described in the detailed description may be made by those skilled in the art without departing from the structure or exceeding the scope of the invention as defined in the claims.
