Description

Technical Field

[0001] The utility model belongs to the technical field of air-cooled generator casings, and more specifically, particularly relates to a spliced ​​silent air-cooled generator casing. Background Art

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. In order to protect the generator, a shell will be installed on the surface of the generator. These shells usually have the conventional functions of silent heat dissipation.

[0003] Based on the above, the inventors have found the following problems: when the current air-cooled generator casing is in use, it is usually divided into an upper and lower shell, which is then hoisted by a crane. During hoisting, the upper and lower shells need to be aligned before they can be spliced. The alignment requires experienced workers and the alignment time is long, resulting in reduced work efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a spliced ​​silent air-cooled generator casing is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a spliced ​​silent air-cooled generator housing to solve the problem that the current generator housing is troublesome when aligning.

[0006] The purpose and effect of the spliced ​​silent air-cooled generator housing of the utility model are achieved by the following specific technical means:

[0007] A spliced ​​silent air-cooled generator casing comprises an upper shell and a lower shell, support plates are installed on both sides of the lower shell, a motor is installed on the surface of the support plate, a winding wheel is installed on the output end of the motor, a raised block is installed on the surface of the lower shell, a circular hole is opened on the surface of the raised block, fixing rods are installed on both sides of the upper shell, and a group of first lifting parts are installed on both sides of the upper shell.

[0008] Furthermore, a mounting hole is provided on the surface of the support plate.

[0009] Furthermore, a set of second hanging parts are installed on both sides of the lower shell.

[0010] Furthermore, cover plates are installed on the surfaces of the upper shell and the lower shell, and threaded holes are opened on the surfaces of the cover plate, the upper shell and the lower shell, and bolts are installed in the threaded holes.

[0011] Furthermore, the surfaces of the upper shell and the lower shell are coated with an anti-rust coating.

[0012] Furthermore, the protruding block is located at a middle position of the surface of the lower shell, and the fixing rod is located at a middle position of the surface of the upper shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model cooperates with the support plate, the motor, the winding wheel, the raised block, the round hole and the fixing rod in use. When the upper shell body and the lower shell body need to be spliced, it is only necessary to pass the traction rope in the winding wheel through the round hole on the surface of the raised block and then connect it with the fixing rod on the surface of the upper shell body. Then, the upper shell body is hoisted above the lower shell body by the first hoisting piece and then the motor is started. The motor startup will drive the winding wheel to rotate, and the rotation of the winding wheel drives the traction rope to tighten. When the traction rope is tightened, the fixing rod and the raised block are located in the same straight line. Then, the upper shell body is slowly lowered and the winding wheel is tightened at the same time to keep the traction rope in a straight state. Through the above design, the upper shell body and the lower shell body can be quickly aligned and spliced, which reduces the difficulty of splicing and improves the splicing efficiency.
