Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment of a hydraulic generator, in particular to a hydraulic generator stator wire bar protection device which is easy to operate. Background Art

[0002] When performing maintenance work on the stator wire rods of the turbine, the wire rods need to be coated with insulating glue and paint. After the glue and paint coating work, the excess glue and paint material attached to the wire rods will flow down along the wire rods until it falls on the floor of the work area, making it difficult to clean the work site. At the same time, the glue and paint that falls on the bottom of the wire rods will form drops, affecting the coating effect of the insulating paint. When the maintenance of the wire rods is completed, if the stator assembly has not been completed, the wire rods cannot be placed in the stator. The on-site placement and protection of the wire rods also become a major maintenance problem. Summary of the invention

[0017] The invention discloses a stator wire rod protection device for a hydro-turbine generator which is easy to operate, comprising a toothed airbag 1, wherein the toothed airbag 1 is composed of a connecting airbag 2 and a tooth airbag 3 which are vertically connected and interconnected, a plurality of tooth airbags 3 are evenly distributed on the connecting airbag 2, and a wire rod clamping gap 4 is formed between adjacent tooth airbags 3. Gas is filled into the toothed airbag 1 to clamp the adjacent tooth airbags 3 to the wire rod 8, thereby preventing glue and paint from flowing downward.

[0018] like Figure 1 As shown in FIG. 1 , the wire rods are accommodated by the wire rod clamping gaps 4 between adjacent tooth airbags 3 , and one tooth airbag 1 can perform protection operations on multiple wire rods at the same time.

[0019] The toothed airbag 1 is provided with an inflation port 5 , and the inflation port 5 is connected to an air pump 6 through an inflation pipeline.

[0020] The toothed airbag 1 is composed of a plurality of layered air chambers 7 which are layered up and down, and the gases between adjacent layered air chambers 7 are isolated.

[0021] like Figure 1 As shown in FIG, by dividing the toothed airbag 1 into a plurality of isolated layered air chambers 7, it is possible to prevent the damage of a certain part of the airbag from causing the overall failure of the airbag.

[0022] Each of the above-mentioned stratified air chambers 7 is provided with an air charging port 5 , which is connected in parallel to an air pump 6 through a pipeline.

[0023] The inflation port 5 is located on the toothed airbag 3 connected to one of the two ends of the airbag 2 .

[0024] By arranging the inflation port 5 at the toothed airbag 3 connected to one end of the airbag 2, it is convenient to connect the air pump 6 and also convenient to place the wire rod 8 into the wire rod clamping gap 4.

[0025] like Figure 2 As shown in , it is a schematic diagram of the airbag performing protective operations, such as Figure 3 As shown in , it is a top view of the protection operation of the upper wire rod, as shown in Figure 4 As shown in , it is a top view of the protection operation on the lower layer of wire rods. The same airbag can be used to perform multiple protection and operations.

[0026] Example:

[0027] A wire rod protection device consists of a layered toothed air bag and an air pump.

[0028] Layered serrated airbag: It is mainly composed of several stacked airbags. The airbag chambers are not connected. The airbag layering is mainly considered when the wire rod is processed. The height of the protection required for each processing step is inconsistent. The layered design can freely adjust the airbag height.

[0029] Air pump: used to inflate the airbag.

[0030] Working principle: When protecting the wire rod, according to the required protection height of the wire rod, the toothed airbag is inflated with an air pump. The toothed airbag will fit tightly with the edge of the wire rod to ensure that the glue and paint will not flow to the protection area during the wire rod processing and will not loosen after the inflation is completed. The airbag material has certain characteristics. First, the airbag is integrally formed without seams; second, it is flexible and foldable, which is convenient for passing through the gap between the upper and lower wire rods during the protection process; third, the airbag does not stick to the epoxy glue and insulating paint and other materials used in the wire rod processing. After the wire rod processing is completed, the gas in the airbag is released and the airbag is pulled out to ensure that the airbag is not damaged or left over due to adhesion; fourth, the airbag material has the characteristics of corrosion resistance and puncture resistance, which ensures that the airbag is not damaged due to accidental contact with tools during the wire rod processing, causing protection failure.
