[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 As shown, the submersible pump top cover assembly comprises a top cover 1 and a handle 2 arranged on the top cover 1 .

[0027] Specifically,

[0028] The handle 2 includes a horizontally arranged bar-shaped gripping portion 2a and two frames 2b respectively arranged vertically below the two ends of the gripping portion 2a. The gripping portion 2a is an arc bar, and the gripping portion 2a and the top cover 1 are arranged coaxially. Preferably, the ratio of the arc length of the gripping portion 2a to the circumference of the whole circle where the gripping portion 2a is located is greater than 1 / 2, so as to provide a larger gripping area and facilitate lifting the submersible pump. Both frames 2b are L-shaped, and the two frames 2b are arranged side by side. Preferably, the upper end of the frame 2b is welded and fixedly connected to the gripping portion 2a.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a strip groove 1a is horizontally penetrated on the outer wall of the top cover 1, that is, both ends of the strip groove 1a are open. The length extension direction of the strip groove 1a is perpendicular to the arrangement direction of the two frames 2b, and the upper side of the strip groove 1a is open. A positioning tube 4 for fixing with the submersible pump cable 3 is horizontally clamped in the strip groove 1a, and the upper side of the positioning tube 4 extends out of the strip groove 1a through the above-mentioned opening.

[0030] The frame 2b is an integrated structure, and the frame 2b is composed of a horizontally arranged positioning plate 2b1 and a vertically arranged connecting plate 2b2. The two positioning plates 2b1 are both fixedly connected to the top cover 1; one of the positioning plates 2b1 presses against the upper side of the positioning tube 4, and two baffles 4a are formed on the upper side of the positioning tube 4. The two baffles 4a are arranged along the length direction of the strip groove 1a, and the two baffles 4a clamp the corresponding positioning plate 2b1.

[0031] During actual installation, the submersible pump cable 3 is passed through the positioning tube 4, and the two are fixed together. Preferably, the cable 3 and the positioning tube 4 are bonded and fixed.

[0032] Two baffles 4a are provided to clamp the corresponding positioning plates 2b1 to firmly limit the positioning tube 4 in the length direction of the strip groove 1a to prevent the cable 3 from being pulled by external force and causing the positioning tube 4 to fall out of the strip groove 1a, so that the cable 3 is more stably limited to ensure stable operation of the submersible pump.

[0033] Preferably, the cross section of the strip groove 1a is arc-shaped, and the shape and size of the lower side of the positioning tube 4 match the strip groove 1a, so that the lower side of the positioning tube 4 is wrapped in the strip groove 1a, and the positioning tube 4 is more stably limited.

[0034] In this embodiment,

[0035] The top cover 1 includes a cover body 1b and a circle of convex ribs 1c formed on the outer wall of the cover body 1b. The convex ribs 1c are L-shaped and vertically arranged, and the upper and lower ends of the convex ribs 1c are respectively arranged on the outer side surface of the cover body 1b and the top surface of the cover body 1b to effectively enhance the strength of the top cover 1.

Preferably, the positioning plate 2b1 is fixedly connected to the corresponding rib 1c by a vertically arranged screw 5, which has the advantages of simple structure and reliable installation.

[0037] like Figure 3 and Figure 4 As shown, the baffle 4a is arc-shaped, and the positioning plate 2b1 is sandwiched between the upper ends of the two baffles 4a. A positioning strip 4b is also horizontally formed on the outer wall of the positioning tube 4. The positioning strip 4b is located between the two baffles 4a, and the two ends of the positioning strip 4b extend to the lower ends of the two baffles 4a. The positioning strip 4b connects the two baffles 4a to effectively enhance the compressive strength of the baffles 4a, thereby clamping the positioning plate 2b1 more forcefully and stably to limit the position of the cable 3 more stably. Preferably, the lower side of the positioning strip 4b is pressed against the edge of the strip groove 1a, so that the positioning tube 4 obtains more powerful support and enhances its positioning strength and stability.

[0038] In actual products, the positioning tube 4 is an injection-molded integral part.
