Description

Technical Field

[0001] The invention relates to the technical field of generators, in particular to a box-type water-cooled generator that is easy to maintain. Background Art

[0002] A water-cooled generator is a generator that uses water as a cooling medium to dissipate heat. During the power generation process, the engine or other energy conversion devices inside the generator will generate a large amount of heat.

Two support mounting plates 96 are rotatably connected to the second worm 914. The support mounting plate 96 is fixedly mounted on the internal scraper ring 98. A driving gear 915 is fixedly connected to the lower end of the second worm 914. A fixed long rack 99 is meshed on the driving gear 915. The fixed long rack 99 is fixedly mounted inside the heat exchange flat tube 7 through a straight plate. A sliding groove is provided on the fixed connecting plate 910, and a sliding support plate 919 is slidably connected in the sliding groove. A fixed T-shaped plate 920 is fixedly connected to one end of the sliding support plate 919 near the connecting cam 912. The connecting cam 912 and the fixed T-shaped plate 920 are positioned at the bottom of the second worm 914. In the same vertical plane, the protrusion on the connecting cam 912 is used to drive the fixed T-plate 920 to move, and the sliding support plate 919 is hinged with two hinged connecting plates 921 at one end close to the connecting cam 912. The driving motor 91 drives the supporting connecting rod 92 to rotate, and the supporting connecting rod 92 drives multiple first worm gears 93 to rotate, and multiple first worm gears 93 drive the first worm gear 94 to rotate, and the first worm gear 94 drives the threaded long rod 95 to rotate.

[0036] The two hinged connecting plates 921 are respectively located on both sides of the fixed T-shaped plate 920, and the end of the hinged connecting plate 921 away from the sliding support plate 919 is hinged with a sliding connecting rod 916, and the end of the sliding connecting rod 916 away from the hinged connecting plate 921 passes through the fixed connecting plate 910, and the sliding connecting rod 916 is slidably connected to the fixed connecting plate 910, and the end of the sliding connecting rod 916 away from the hinged connecting plate 921 is fixedly connected to a movable knocking plate 917, and the end of the movable knocking plate 917 close to the fixed connecting plate 910 is fixedly connected A return spring 918 is connected, and one end of the return spring 918 away from the movable knocking plate 917 is fixedly connected to the fixed connecting plate 910.

The sliding support plate 919 drives the two sliding connecting rods 916 to move closer to each other through the two hinged connecting plates 921, and the sliding connecting rod 916 drives the moving knocking plate 917 to move closer to the fixed The fixed connecting plate 910 and the return spring 918 are squeezed. When the protrusion on the connecting cam 912 is disengaged from the fixed T-plate 920, the movable knocking plate 917 is reset under the elastic action of the return spring 918, so that the movable knocking plate 917 continuously knocks the inner wall of the heat exchange flat tube 7. The knocking can weaken the adhesion between the scale and the inner wall of the heat exchange flat tube 7, and cause cracks in the scale layer, which is easier to be scraped off by the internal scraper ring 98, thereby realizing the cleaning and maintenance of the inside of the heat exchange flat tube 7.

The plurality of stirring plates 134 stir the liquid flowing in the heat exchange flat tube 7, thereby improving the fluidity of the cooling water and the heat transfer efficiency.

[0038] In actual use, cold water is introduced into the heat exchange flat tube 7 through the water inlet pipe 5, and then heat is exchanged through the multiple heat dissipation fins 12, thereby achieving cooling of the equipment. When water passes through the heat exchange flat tube 7, the water flow drives the fixed inclined plate 133, causing the first fixed column 132 to rotate.
