Description

Technical Field

[0001] This utility model invention patent belongs to a lifting ring device for a rubber sewage pipe on a submersible sewage pump and a floating ring combination. In fact, it is a mechanical device that uses a tension spring lifting ring combination to greatly reduce the swing amplitude of the rubber sewage pipe when the submersible sewage pump and the floating ring combination discharges sewage. Technical Background

[0002] During construction, sewage with high sediment content needs to be discharged. If a submersible sewage pump and a floating ring are used, we must face the problem of how to constrain the rubber sewage pipe. When the equipment installation position is determined, the length of the rubber sewage pipe is fixed, but the height of the submersible sewage pump and the floating ring combination in the sewage pool is variable. When the sewage pool is at a high water level, the rubber sewage pipe will bend upward. If the bent rubber sewage pipe is not constrained, it will swing violently. Over time, the interface between the rubber sewage pipe and the steel pipe will be disconnected, making it impossible to continue sewage discharge. Using a new type of submersible sewage pump and floating ring combination of rubber sewage pipe lifting ring device can solve this problem well. Summary of the invention

[0003] A new type of lifting ring device for a rubber sewage pipe on a submersible sewage pump and a floating ring assembly includes a lifting ring, a six-sided frame, three curved rollers with bearings, a base, a hook, and a tension spring and a rubber sewage pipe that cooperate with it. Using the principle of triangle stability, the three curved rollers with bearings in the lifting ring are at an angle of 60° to each other, and the diameter of their inscribed circle is just equal to the outer diameter of the rubber sewage pipe. A hook that can rotate 360° is provided on the top of the lifting ring, which facilitates the rubber sewage pipe to twist in different directions.

[0004] The technical feature of the utility model is that the friction and triangle stability principle are utilized, and the two ends of the three rollers of the hanging ring are equipped with bearings that reduce friction, and they form a triangle with each other, so that the rubber sewage pipe can remain relatively stable when being hung, and can slide freely in the hanging ring when being extended or retracted.

[0005] The technical feature of the utility model is that a hook with a twistable neck is designed on the top of the lifting ring, which can meet the needs of slight twisting of the rubber sewage pipe and avoid damage to the rubber sewage pipe due to hard wear with the roller.

[0006] The technical feature of the utility model is that a tension spring is arranged on the lifting ring. When the water level of the sewage pool drops, the tension spring is stretched due to the weight of the submersible sewage pump and the floating ring combination to make up for its downward height. When the water level of the sewage pool rises, the tension spring contracts so that the submersible sewage pump and the floating ring combination are always within the constraint range.

[0007] The utility model has the beneficial effect that the combination of the tension spring and the lifting ring effectively restrains the rubber sewage pipe on the submersible sewage pump and the floating ring assembly, thereby avoiding accidents caused by violent swinging.

[0010] 5.Hook 6.Rubber drain pipe 7.Extension spring DETAILED DESCRIPTION

[0011] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0012] According to the principle of triangle stability, the bases (4) of six arc-surface rollers (3) with bearings are welded in the hexagonal frame (2), so that the angle between the three arc-surface rollers (3) with bearings is 60 degrees, and the diameter of their inscribed circles is just equal to the outer diameter of the rubber sewage pipe (6). The hook (5) is installed in the middle of the top of the hexagonal frame (2) and can rotate 360 ​​degrees. The lifting ring (1) is put on the turning point of the rubber sewage pipe (6), and the hook (5) is connected to the lower end of the tension spring (7), and the upper end of the tension spring (7) is fixed at a high hanging point. Thus, a new type of submersible sewage pump and floating ring assembly is assembled with a lifting ring device for the rubber sewage pipe (6).

[0013] The working process of the utility model is as follows: according to Archimedes' law of buoyancy and Hooke's law of elasticity, when the sewage in the sewage pool is discharged, the water level drops, and the forces acting on the combination of the submersible sewage pump and the floating ring are gravity> buoyancy+elasticity. When the sewage pool is at the lowest water level, the tension spring (7) is stretched to the longest. When the sewage pool is filled with sewage, the water level continues to rise, and the force acting on the combination of the submersible sewage pump and the floating ring is buoyancy+elasticity>gravity. When it continues to rise to the highest water level, the tension spring (7) returns to the initial state. During the whole process, the rubber sewage discharge pipe (6) on the submersible sewage pump and the floating ring combination has never been freed from the constraint of the lifting ring (1), avoiding its violent swing.
