[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figure 1 As shown, a submersible electric pump condition monitor installation tool includes a locking ring group and a support column group connected to the locking ring; the locking ring group includes at least one locking ring, and the locking ring includes a locking upper half ring 1 and a locking lower half ring 4, one end of the locking upper half ring 1 and the locking lower half ring 4 are hinged, and the other end is connected by a locking device 3; the support column group includes a plurality of support columns 2 evenly distributed along the circumference, one end of the support column 2 is fixedly connected to the locking lower half ring 4; the locking ring is coaxially arranged with the motor of the submersible electric pump unit, and the pump condition monitor is placed on the support column group.

[0019] After the pump condition monitor is placed on the supporting column assembly, the pump condition monitor is coaxial with the motor of the submersible electric pump assembly.

[0020] The circumference surrounded by the plurality of support columns 2 is coaxially arranged with the locking ring.

[0021] A connecting plate 5 is provided at the other end of the supporting column group, and the connecting plate 5 is an arc-shaped plate.

[0022] When the locking ring group includes multiple locking rings, the multiple locking rings are evenly distributed along the axis, and adjacent locking lower half rings are connected by connecting columns, and the number of connecting columns is consistent with the number of support bodies 2 and is arranged one-to-one.

[0023] When the support column 2 is longer, an auxiliary connecting plate is provided at one end of the support column group close to the locking ring group. The auxiliary connecting plate and the connecting plate 5 have the same shape and size, and are arranged parallel to each other.

[0024] The locking device 3 is a conventional part, and any workpiece that can be opened and closed and locked can be applied to this application.

[0025] In this embodiment, the locking device 3 includes a male buckle fixed to the edge of the arc-shaped outer wall of the locking upper half ring 1 and a female buckle fixed to the edge of the arc-shaped outer wall of the locking lower half ring 4; the female buckle is a rectangular plate structure, and a U-shaped notch is formed at one end away from the center of the locking ring; the male buckle includes a buckle plate and a buckle column arranged at the bottom of the buckle plate, and a limiting ring is formed on the buckle column; the bottom surface of the male buckle is flush with the end face of the locking upper half ring 1, and the bottom surface of the female buckle is flush with the end face of the locking lower half ring 4; after the male buckle and the female buckle are buckled together, the buckle column is inserted into the U-shaped notch, and the limiting ring is clamped on the bottom surface of the female buckle to achieve locking of the locking upper half ring 1 and the locking lower half ring 4.

[0026] The use method of this utility model:

[0027] When the tool of the present application is in use, it is fixed to the installation position of the pump condition monitor at the tail of the motor of the submersible electric pump unit by locking the upper half ring 1 and the lower half ring 4 together. After the installation of the upper and lower half rings is completed, the central axis of the circular ring formed by them is on the same line as the central axis of the motor. The pump condition monitor is then placed on the support column 2 of the tool. The support column 2 is designed so that after the pump condition monitor is placed, the central axis of the pump condition monitor is on the same line as the central axis formed by the locking device before. This ensures that the motor and the pump condition monitor are on the same line. Afterwards, the pump condition monitor is pushed along the support column 2 to slide toward the submersible motor body to complete the docking of the motor and the pump condition monitor. The structural design ensures that the central axes of the pump condition monitor and the submersible motor body are on the same straight line to avoid damage to the threads and O-rings due to axis offset.
