Description

Technical Field

[0001] The utility model relates to a submersible motor supporting structure for a submersible sewage pump installed horizontally. Background Art

[0002] The submersible sewage pump in the prior art is usually installed vertically. When installed horizontally, a motor bracket and a pump bracket are provided. The motor support structure is composed of a motor bracket and a clamp. Figure 1 , Figure 2 . Motor bracket see Figure 3 , Figure 4 , see the hoop Figure 5 The motor bracket needs to be welded, semicircularly bored by a boring machine, and drilled and tapped by a drilling machine. The clamp needs to be rolled, cut, and welded. Multiple parts correspond to multiple costs and production cycles, and an improved structure is urgently needed to solve the cost and production cycle problems. For conventional horizontal installation, see Figure 1 , 31 motor bracket, 32 pump, 33 pump bracket, 34 fastener, 35 terminal block, 36 clamp, 37 motor upper end cover. The pump is supported by the motor bracket 31 and the pump bracket 33. The submersible motor is partially supported by the motor bracket, and the supporting parts are the flange outer circle of the motor upper end cover 37 and the terminal block 35. The clamp 36 clamps the upper half of the flange outer circle of the motor upper end cover 37 and the terminal block 35. The motor bracket 31 supports the lower half of the flange outer circle of the motor upper end cover 37 and the terminal block 35. The fastener 34 fastens the clamp 36 and the motor bracket 31. See the motor bracket structure.

Summary of the invention

[0003] The utility model aims at the above-mentioned problems existing in the prior art and provides a submersible motor support structure for a submersible sewage pump installed horizontally. The utility model designs a submersible motor support structure for a submersible sewage pump installed horizontally, including a submersible sewage pump and a submersible motor. The submersible sewage pump is installed at the rear end of the submersible motor. A pump bracket is arranged at the bottom of the tail end of the submersible sewage pump. The utility model is characterized in that two bosses are arranged on the left and right sides of the bottom surface of the upper end cover of the submersible motor, the bosses and the bottom surface of the upper end cover of the submersible motor form a boss plane, a threaded hole is arranged on the bottom surface of the bosses, and a motor bracket is arranged under the upper end cover of the submersible motor. The motor bracket is welded by a mounting plate 9, a support plate, a reinforcing rib, and a bottom plate. The support plate and the reinforcing rib are welded to the bottom of the mounting plate, and the bottom plate is welded to the support plate and the bottom surface of the reinforcing rib. Anchor holes are opened at both ends of the bottom plate, and screw holes are opened at both ends of the mounting plate. The motor bracket is fixed to the submersible motor by bolts in the screw holes at both ends of the mounting plate being screwed into the threaded holes opened on the bottom surface of the boss of the upper end cover of the submersible motor. The advantages of the utility model are: the support position of the submersible motor installed horizontally in the submersible sewage pump is changed from the casing position to the upper end cover of the motor. The original support scheme has support members arranged around the motor casing, and motor brackets and clamps are arranged, and the casing has a large circumference and large supporting consumables. After the support position of the current support scheme is changed to the upper end cover of the motor, especially the bottom of the upper end cover of the motor is selected, the support area is small. The support height is reduced and the stability is improved. The support structure has made slight changes to the structure of the upper end cover of the motor, and a small plane protrudes below the outer circle on the top side of the upper end cover of the motor, which is flush with the plane on the motor bracket mounting plate. The motor bracket structure is improved. After the improvement, the material used for the motor bracket is saved, the processing amount is reduced, and the parts clamps are reduced under the submersible motor mounting structure.

[0012] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0013] The figure shows a submersible sewage pump horizontally mounted submersible motor support structure, comprising a submersible sewage pump 1 and a submersible motor 2. The submersible sewage pump is mounted at the rear end of the submersible motor, and a pump bracket 3 is arranged at the bottom of the tail end of the submersible sewage pump. The submersible sewage pump is characterized in that two bosses 5 are arranged on the left and right sides of the bottom surface of the upper end cover 4 of the submersible motor, and the bosses and the bottom surface of the upper end cover of the submersible motor form a boss plane 6. A threaded hole 7 is arranged on the bottom surface of the boss, and a motor bracket 8 is arranged under the upper end cover of the submersible motor. The motor bracket is welded by a mounting plate 9, a support plate 10, a reinforcing rib 11, and a bottom plate 12. The support plate 10 and the reinforcing rib 11 are welded to the bottom of the mounting plate, and the bottom surface of the support plate 10 and the reinforcing rib 11 are welded to the bottom surface of the bottom plate 12. Anchor holes 13 are opened at both ends of the bottom plate, and screw holes 14 are opened at both ends of the mounting plate. The motor bracket is fixed to the submersible motor by screwing bolts 15 in the screw holes at both ends of the mounting plate into the threaded holes opened on the bottom surface of the boss of the upper end cover of the submersible motor.

[0014] During production, the motor bracket is welded by the mounting plate, support plate, reinforcement ribs and bottom plate. After welding, the upper plane of the mounting plate is milled, and the screw holes on the upper plane and the anchor holes on the bottom plate are drilled in sequence.

[0015] The outer ring of the upper end cover of the submersible motor protrudes downwards to form a boss bottom surface to connect with the motor bracket, which is flush with the plane of the motor bracket mounting plate. Two threaded holes are processed on the bottom surface of the boss, which are connected with the screw holes on the plane of the motor bracket mounting plate through bolts.

[0016] Compared with the original structure, the new horizontal structure has fewer clamps on the motor support part, and the support part is located below the horizontal center of the pump. The support height is low and the support area is small, so the motor bracket saves material and requires less processing.
