Description

[Detailed description of the invention]

[0001]

[Technical field of invention]

 The present invention relates to a motor-mounted structure of a vertical submersible electric pump.

[0002]

[Background of the invention]

 As is well known, the submersible pump is installed in the pumped water, so it is inevitable that the pumped contaminants adhere to the outside. In particular, when a submersible pump is used to discharge sludge or concrete mixed liquid at a civil engineering site, sludge or cement adheres to the outer peripheral surface or top surface of the motor. There is no problem because the pump is constantly immersed in the liquid during the discharge of the pumped liquid.However, the motor used when exposed to the liquid surface is exposed to the atmosphere and sunlight, and thus adheres to sludge and cement. Will dry and stick. The outer surface and top surface of the motor are finished with lacquer, melamine paint, etc., and the painted surface is easily damaged.Therefore, the work of scraping off the attached sludge and cement must be performed very carefully, and the pump must be used. Not only does it take a lot of time and effort to clean up later, but it often also damages the painted surface and requires painting restoration during cleaning.

[0003]

[Purpose of the invention]

 The purpose of the present invention is to prevent sludge and cement from adhering to the outer peripheral surface and top surface of the motor part exposed on the liquid surface, to prevent troublesome cleaning after using a submersible pump for civil engineering work, and to apply painting. In order not to damage the surface.

[0004]

[Structure of device]

 The motor-mounted structure of the vertical submersible electric pump according to the present invention is a soft synthetic resin that is formed into a contour shape that matches the top surface of the motor, and is provided with through-holes that lead out the wire lead-out section and the hand section. The heat-shrinkable tube formed with a sheet made of a heat-shrinkable tube and an upper end opening bent into an inwardly bent abutting edge and a surplus part formed so as to fit with the peripheral side surface of the motor part is formed as a through-hole. A flexible synthetic resin sheet is attached to the top surface of the motor with the electric wire draw-out part and the handle part protruding from inside, and the heat-shrinkable tube is fitted to the peripheral side surface of the motor part to fit the inner part. The bent contact edge is in contact with the periphery of the soft synthetic resin sheet, and the top surface and the peripheral side surface of the motor portion are covered by heat-shrinking the heat-shrinkable tube.

【Example】

 Hereinafter, description will be made with reference to the drawings of the embodiments.

[0006] Reference numeral 1 denotes a top surface of a motor unit in a vertical submersible electric pump to which the present invention is applied, and 2 denotes a peripheral side surface. Reference numeral 3 denotes a sheet made of a soft synthetic resin formed in a contour shape conforming to the top surface 1 of the motor portion. Holes 6 ‥‥ 6 are provided, and for example, vinyl chloride, nylon, or polyethylene soft synthetic resin is preferable. Reference numeral 7 denotes a heat-shrinkable tube formed so as to be fitted to the peripheral side surface of the motor portion. For example, a heat-shrinkable tube made of polyvinyl chloride, polyolefin, or polyethylene terephthalate is preferable. The bending edge 8 is bent.

[0007] When the submersible pump is used, the electric wire lead-out part 4 and the handhold part 5 are protruded from the inside of the through holes 6 # 6 using the soft synthetic resin sheet 3 and the heat-shrinkable tube 7 as covering materials. In this state, the soft synthetic resin sheet 3 is brought into contact with the top surface 1 of the motor portion, and the heat-shrinkable tube 7 is fitted into the peripheral side surface 2 of the motor portion, thereby forming an inner bent attachment edge. When the heat-shrinkable tube 7 is heated and shrunk by blowing hot air or the like, the top surface 1 and the periphery of the motor portion are formed. The side surface 2 will be covered by the covering material. Therefore, the sludge and cement do not directly adhere to the top surface 1 and the peripheral side surface 2 of the motor portion, but adhere to the surface of the soft synthetic resin sheet 3 and the heat-shrinkable tube 7 which are covered.

After use of the submersible pump, the adhered matter can be easily removed by peeling off the soft synthetic resin sheet 3 and the heat-shrinkable tube 7 from the motor section. It is sufficient to wash off only the deposits on the strainer 9 of the pump part. However, since this part was always submerged in the water during the drainage work, the attached sludge was not dried. Is very easy.

[0009]

[Effect of the invention]

 According to the present invention, since the motor part of the submersible pump is covered by the covering material, the sludge and cement are not covered by the covering material even when used for discharging sludge or concrete mixed liquid at a civil engineering work site. The motor part is not contaminated by adhering to the surface, and only the deposits on the strainer of the pump part need to be washed off slightly, which makes cleaning after use easy and convenient. There is no risk of damaging the painted surface.
