Description

Technical Field

[0001] This utility model invention patent belongs to a plastic float and submersible sewage pump locking device, which is actually a mechanical device that uses the principle of friction to lock the plastic float and the submersible sewage pump. Technical Background

[0002] In the past, the plastic float was fixed to the submersible sewage pump body by wire binding. However, due to the strong vibration generated by the submersible sewage pump when it is draining water, the wire tied to the submersible sewage pump will be gradually loosened over time. The submersible sewage pump will slide from the central hole of the plastic float to the silt at the bottom of the sewage pool due to gravity, making the submersible sewage pump surrounded by silt. If it is not discovered in time during the sewage discharge process, the submersible sewage pump will not be able to pump water, and the rotor and stator will not be cooled, and will burn out over time. This new device that firmly locks the plastic float and the submersible sewage pump can solve the above problems very well. Utility Model Content

[0003] A new type of device for firmly locking a plastic float and a submersible sewage pump involves a submersible sewage pump, a plastic float, a 50×50 angle steel, an Ω-shaped clamp, an M10 positioning bolt, an M12 locking long bolt, an M12 nut and other components and elements. Four holes with M10 internal threads are symmetrically set at every 90° rotation on the center ring of the plastic float. At the same time, a clamp with Φ14 circular holes at both ends is made according to the circumference of the submersible sewage pump body, and a 50×50 angle steel with a length equal to the outer radius of the float minus the radius of the pump body is welded at the center and one end of each of the clamps. Assuming the outer diameter of the float is R and the inner diameter is r, then the corresponding float of the angle steel A Φ12 round hole is made on the horizontal side of the pump. When ready, put the plastic float ring on the pump body of the submersible sewage pump, adjust the height of the float ring, clamp the Ω-type clamp around the pump body, and use M10 bolts to fix the angle steel at one end of the Ω-type clamp to the internal thread of the plastic float ring. Then use M12 locking bolts to tightly connect the two hoops. Finally, use M10 bolts to tightly connect the central holes of the two angle steels welded to the center of the two hoops and the internal threaded hole of the float ring. In this way, the assembly of the fixing device is completed.

[0004] The technical feature of the utility model is that the friction force generated between the clamp and the pump body of the submersible sewage pump is much greater than the downward gravity of the submersible sewage pump by using the principle of friction force and the method of tightening bolts, so that the submersible sewage pump cannot escape the control of the plastic float.

[0005] The technical feature of the utility model is that it utilizes the principle of symmetry and symmetrically arranges small holes with M10 internal threads on the plastic float, so that the center of gravity of the plastic float and the center of gravity of the submersible sewage pump are always on the same vertical line, thereby ensuring that the combination of the submersible sewage pump and the plastic float remains balanced when stationary.

[0006] The beneficial effects of the utility model are as follows: the submersible sewage pump is firmly locked on the plastic float ring, the submersible sewage pump will not sink into the mud due to the effect of buoyancy, and the center of gravity of the submersible sewage pump and the center of gravity of the plastic float ring are located on the same vertical line, no matter how the submersible sewage pump is disturbed during operation, the submersible sewage pump will not slip out of the plastic float ring, thus avoiding the accident of the submersible sewage pump being buried and burned by the mud, and greatly extending the service life of the submersible sewage pump.

[0008] The utility model will now be described in detail with reference to the accompanying drawings and specific implementation modes.

[0009] The utility model is the result of innovating the old connection method of binding a submersible sewage pump (1) and a plastic float (2) with iron wire. The utility model is associated with a submersible sewage pump (1), a plastic float (2), and M10 internal threaded holes (3) symmetrically distributed on the plastic float, a 50×50 angle steel (4) welded on an Ω-shaped clamp (6), an M10 positioning bolt (8) and a Φ12 through hole (5), so as to realize connecting the combination of the 50×50 angle steel (4) and a pair of Ω-shaped clamps (6) with the plastic float (2), and an M12 locking long bolt (9) passing through the Φ14 through holes (7) at both ends of the pair of Ω-shaped clamps (6) and tightening with an M12 nut (10), so as to complete the strong connection between the plastic float (2) and the submersible sewage pump (1).

[0010] The production process of this utility model:

[0011] 1. Four M10 internal threaded holes (3) are symmetrically arranged on the central ring line of the plastic float (2), with the angle between them being 90°. Then, a pair of Ω-shaped clamps (6) are made, with Φ14 through holes (7) punched at both ends. A 50×50 angle steel (4) with a length equal to the outer diameter of the float minus the outer diameter of the pump body is welded to the center and one end. The outer diameter of the float is R, and the inner diameter is r. Open a Φ12 through hole (5) on the horizontal side and prepare an M10 positioning bolt (8), an M12 locking long bolt (9), and an M12 nut (10).

[0012] 2. Put the plastic float (2) on the submersible sewage pump (1) from top to bottom, and adjust the relative height between the plastic float (2) and the submersible sewage pump (1). Then place the combination of two Ω-shaped clamps (6) and 50×50 angle steel (4) on both sides of the submersible sewage pump body. M10 positioning bolts (8) are passed through one end of the Ω-shaped clamp (6) and the 50×50 angle steel (4) welded in the center to the corresponding float. The Φ12 through hole (5) on the horizontal side is screwed into the plastic float (2). The connection between the M10 internal threaded hole (3) at the horizontal side, the Ω-shaped clamp (6) and the plastic float (2) is completed.

[0013] 3. Use M12 locking long bolts (9) to pass through the Φ14 through holes (7) punched at both ends of the Ω-shaped clamp (6), put on M12 nuts (10) and tighten them in sequence. The submersible sewage pump (1) and the plastic float (2) are then tightly connected together. Even if the submersible sewage pump (1) is disturbed for a long time during operation, they will not loosen from each other.
