Description

Technical Field

[0001] The utility model relates to a lifting pump fastening device. Background Art

[0002] The structure of the lift pump is divided into two parts, the upper part is the motor, and the lower part is the impeller and volute. The upper and lower structural parts are connected by a steel buckle in the middle.

[0003] When the lift pump is running underwater, if the base is loose or other faults occur, the pump body will vibrate excessively. If the external force generated by the vibration is too large, the steel clip will be damaged, causing the upper and lower structures of the lift pump to separate.

[0004] The lifting mechanism of the lift pump is fixed to the upper structure of the pump body. When a fault causes the upper and lower structures of the pump body to separate, maintenance personnel are unable to lift the lower structure out of the water. Utility Model Content

[0005] The utility model aims to provide a lifting pump fastening device, which is used to solve the problem that when the external force generated by vibration is too large, the steel buckle will be damaged, resulting in the separation of the upper and lower structures of the lifting pump.

[0006] In order to solve the above problems, the technical solution of the utility model is:

[0007] The lifting pump fastening device includes a sleeve ring which is sleeved on the conical surface of the lifting pump, a plurality of folded strips are fixedly connected around the sleeve ring, and a plurality of curved strips are supported on the bottom of the lifting pump, the two ends of the curved strips have outward bending sections, and the bending sections at both ends of the curved strips are connected to the folded strips through fasteners.

[0008] A rubber strip is provided between the collar and the lift pump.

[0009] Ribs are arranged at the lower end of the folding strip and on the bending section.

[0010] The sleeve ring, folding strip, curved strip and fastener are all made of stainless steel.

[0011] The fastener comprises a screw rod and a self-locking nut.

[0012] The beneficial effect of the utility model is that the upper and lower parts of the lifting pump are firmly fixed together by the fastening device, thereby strengthening the impact resistance of the upper and lower structures of the lifting pump when encountering external vibration forces, avoiding the separation of the upper and lower structures, and reducing the cost of replacing the steel buckles originally configured in the factory. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings:

[0014] Figure 1 It is a three-dimensional structural schematic diagram of the utility model.

[0015] In the figure: lifting pump 1, collar 2, rubber strip 3, folding strip 4, self-locking nut 5, screw 6, curved strip 7, rib 8. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The lifting pump fastening device includes a ring 2 which is sleeved on the conical surface of the lifting pump 1, a plurality of folded strips 4 are fixedly connected around the ring 2, and a plurality of U-shaped curved strips 7 which are supported on the bottom of the lifting pump 1. The curved strips 7 have outwardly bent sections at both ends, and the bent sections at both ends of the curved strips 7 are connected to the folded strips 4 through fasteners.

[0018] When in use, the collar 2 is put onto the upper conical surface of the lift pump 1, and then the curved bar 7 is used to support the bottom of the lift pump 1, and then the upper and lower structures of the lift pump 1 are fixed together using fasteners.

[0019] A rubber strip 3 is provided between the collar 2 and the lift pump 1. The rubber strip 3 can prevent the collar 2 from scratching the housing of the lift pump 1 and also has a shock absorbing effect.

[0020] Ribs 8 are provided at the lower end of the folding strip 4 and the bending section to improve the strength of the folding strip 4 and the bending section to prevent them from deforming when tightening the screws.

[0021] The collar 2, the folding strip 4, the curved strip 7 and the fastener are all made of stainless steel. Because the lift pump 1 is operated underwater, the fastening device has been selected to be made of stainless steel to avoid rust and corrosion.

[0022] The fastener comprises a screw rod 6 and a self-locking nut 5. The self-locking nut 5 can prevent the lift pump 1 from loosening during use.

[0023] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
