[0002] The sewage lifting pump is a pump product that integrates a pump, a motor, a casing, and a control system. It can be used for sewage lifting and can work on the ground or underwater. In order to assist the lifting pump in stable use, a lifting pump with a protective structure is required.

[0003] During use, traditional lifting pumps mostly use the side connection port to connect with the external pipe, and connect the connection port on the top of the lifting pump to the external pipe, so as to assist in stably lifting the water source near the bottom and guiding it to the top area. However, during the installation and use of traditional lifting pumps, the outer surface of the lifting pump body is easily affected by the external environment, which may cause damage to the lifting pump body, thereby affecting the service life of the lifting pump body and the stable use of the lifting pump. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a lift pump with a protective structure to solve the problems raised by the above background technology.

[0005] The utility model provides the following technical solutions: a lifting pump with a protective structure, comprising a lifting pump body, an annular groove is provided on the outer edge of the lifting pump body, an arc-shaped plate is overlapped on the inner wall of the annular groove, a cylinder is fixedly assembled on the outer edge of the arc-shaped plate, a round rod is slidably sleeved on the inner wall of the cylinder, an auxiliary plate is fixedly assembled on the side of the round rod, a fixed frame is fixedly assembled on the side of the auxiliary plate, a slide is slidably connected to the nickel coin of the fixed frame, a threaded groove is provided on the inner wall of the slide, and a threaded rod is threadedly connected to the inner wall of the threaded groove.

[0006] As a preferred technical solution of the present invention, a spring is fixedly connected to the side of the inner wall of the cylinder, and one end of the spring away from the inner wall of the cylinder is fixedly connected to the side of the round rod.

[0007] As a preferred technical solution of the present invention, a slot is provided on the side of the fixing frame, an adjusting wheel is rotatably sleeved on the inner wall of the slot, and the top of the adjusting wheel is fixedly assembled with the bottom of the threaded rod.

[0008] As an optimal technical solution of the present invention, there are two arc-shaped plates, and the outer edges of the two arc-shaped plates overlap the inner wall of the annular groove. The inner walls of the two arc-shaped plates are slidably sleeved with bolts, and the outer edges of the bolts are threaded with nuts.

[0009] As a preferred technical solution of the present invention, the number of the cylinders is eight, and the eight cylinders are grouped into four and fixedly assembled with the outer edges of the two arc-shaped plates respectively, and the internal connection structures of the eight cylinders are completely consistent.

[0010] As an optimal technical solution of the present invention, the number of the threaded rods is sixteen, and the sixteen threaded rods are grouped into two and fixedly assembled with the top and bottom of the eight adjusting wheels respectively, and the outer edges of the sixteen threaded rods are all threadedly connected to a slide.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The lifting pump with a protective structure cooperates with the use of an arc plate and a cylinder. The two arc plates are connected by bolts and nuts to assist in the stable installation of the cylinder. When the fixed frame is impacted by the external environment, the fixed frame drives the round rod to slide in the inner wall of the cylinder, and uses the spring to assist in limiting the round rod while pushing the round rod to move away from the cylinder, thereby assisting in shock absorption of the fixed frame and thus assisting in protecting the lifting pump body.

[0013] 2. The lifting pump with a protective structure uses an adjusting wheel and a threaded rod in combination. The adjusting wheel drives the threaded rod to rotate, and then the threaded rod drives the slide to slide in the inner wall of the fixed frame, thereby assisting the two slides to move away from the adjusting wheel, thereby assisting in extending the installation area of ​​the slide and the fixed frame, and thus providing stable protection for the lifting pump body.
