Description

Technical Field

[0001] The utility model belongs to the technical field of sewage pumps, and particularly relates to a sewage pump. Background Technique

[0002] A sewage pump is a device used to transport wastewater or sewage containing solid particles or fibers. It is usually used in drainage systems, including sewage treatment plants, sewage collection systems, urban drainage systems, as well as industrial and construction fields. A lifting ring is installed on the outside of the sewage pump housing. Through the lifting ring, the sewage pump can be installed. The pump is lifted by a lifting device and installed at the required position to ensure the correct installation and positioning of the pump. When the sewage pump needs to be repaired or replaced, the lifting ring can be used to disassemble the pump from the installation position, facilitating maintenance or replacement work.

[0003] When moving the position of the sewage pump, it is often necessary to cooperate with a lifting rope on the lifting ring and use a lifting device to lift it. This method requires restricting the lifting rope at the position of the lifting ring. Not only does it need to connect the lifting ring, but also the lifting device, making the operation during position movement rather troublesome. Content of the Utility Model

[0004] The utility model provides a sewage pump, which has the characteristics of being convenient to connect with a lifting device and facilitating the installation of the sewage pump through the setting of a connecting and hidden lifting rope.

[0005] The utility model provides the following technical solution: a sewage pump, including a pump body. Two base plates are fixedly connected to the top of the pump body. Lifting rings are fixedly installed on both of the two base plates. A connecting and hidden lifting rope is arranged outside the pump body. Two ends of the connecting and hidden lifting rope are respectively fixedly connected to the two lifting rings. An internal concave cavity is formed in the pump body. The connecting and hidden lifting rope is located in the internal concave cavity. And a protective shielding shell is inserted into the internal concave cavity. Hiding the protective shielding shell into the internal concave cavity can reduce the occupied volume and provide protection. Two outer pasted limiting plates for restricting the position are arranged on the outside of the protective shielding shell.

[0006] Wherein, the outer end face of the protective shielding shell is flush with the outer end face of the pump body. The protective shielding shell is provided with an avoidance hole corresponding to the connecting and hidden lifting rope.

[0007] Wherein, one end of the connecting and hidden lifting rope is wound and tied to the lifting ring, and a winding film is arranged at the connecting part of the connecting and hidden lifting rope and the lifting ring.

[0008] Wherein, the two outer pasted limiting plates are staggeredly distributed on the outside of the protective shielding shell. The end face of the outer pasted limiting plate is attached to the outer end face of the protective shielding shell. Two corner buckling grooves are formed in the protective shielding shell.

[0009] Wherein, the base plate is provided with a telescopic mounting groove, and the externally attached limiting plate is slidably connected in the telescopic mounting groove.

[0010] Wherein, a limiting spring is fixedly connected in the telescopic mounting groove, and one end of the limiting spring is fixedly connected to the externally attached limiting plate.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By setting that both ends of the connecting hidden lifting rope are fixedly connected to two lifting rings respectively, the pump body is provided with an internal concave cavity, the connecting hidden lifting rope is located in the internal concave cavity, and a protective shielding shell is inserted in the internal concave cavity. The protective shielding shell is hidden in the internal concave cavity to reduce the occupied volume and provide protection. During use, the position of the externally attached limiting plate can be slid, and the externally attached limiting plate is moved away from the outside of the protective shielding shell, so that the connecting hidden lifting rope located in the internal concave cavity can be extended, thereby facilitating the connection with the hoisting equipment. The installation of the sewage pump is facilitated through the setting of the connecting hidden lifting rope.

[0013] Parts not involved in this device are the same as or can be implemented using existing technologies. Description of the Drawings

[0020] In this implementation scheme: Two base plates 11 are fixedly connected to the top of the pump body 1. Hoisting rings 12 are fixedly installed on both of the two base plates 11. A connecting and hidden lifting rope 3 is arranged outside the pump body 1. One end of the connecting and hidden lifting rope 3 is wound and tied to the hoisting ring 12, and a winding film is arranged at the connecting part of the connecting and hidden lifting rope 3 and the hoisting ring 12. The connecting and hidden lifting rope 3 is fixed in advance and protected by the winding film, which brings convenience in the process of shifting the sewage pump later. By setting that two ends of the connecting and hidden lifting rope 3 are respectively fixedly connected to the two hoisting rings 12, the pump body 1 is provided with an internal concave cavity 13. The connecting and hidden lifting rope 3 is located in the internal concave cavity 13, and a protective shielding shell 2 is inserted into the internal concave cavity 13. The protective shielding shell 2 is hidden in the internal concave cavity 13 to reduce the occupied volume and provide protection. When in use, the position of the outer pasted limiting plate 4 can be slid, and the outer pasted limiting plate 4 is moved away from the outer side of the protective shielding shell 2, so that the connecting and hidden lifting rope 3 located in the internal concave cavity 13 can be extended, thereby facilitating the connection with the hoisting equipment. The setting of the connecting and hidden lifting rope 3 can facilitate the installation of the sewage pump. When the connecting and hidden lifting rope 3 is not in use, the connecting and hidden lifting rope 3 can be located in the internal concave cavity 13, and then the protective shielding shell 2 is covered. By restricting the two outer pasted limiting plates 4 on the outer side of the protective shielding shell 2, the limiting spring 5 exerts a resistance on the outer pasted limiting plate 4, thereby stably restricting the position of the outer pasted limiting plate 4 on the protective shielding shell 2.

[0021] The outer end face of the protective shielding shell 2 is flush with the outer end face of the pump body 1. The protective shielding shell 2 is provided with an avoidance hole corresponding to the connecting and hidden lifting rope 3; The connecting and hidden lifting rope 3 is located in the internal concave cavity 13, and then the protective shielding shell 2 is covered. The avoidance hole can avoid the connecting and hidden lifting rope 3. The outer end face of the protective shielding shell 2 is flush with the outer end face of the pump body 1, which does not affect the external use of the pump body 1.

[0022] One end of the connecting and hidden lifting rope 3 is wound and tied to the hoisting ring 12, and a winding film is arranged at the connecting part of the connecting and hidden lifting rope 3 and the hoisting ring 12; The connecting and hidden lifting rope 3 is fixed in advance and protected by the winding film, which brings convenience in the process of shifting the sewage pump later.

The end face of the externally attached limiting plate 4 is attached to the outer end face of the protective shielding housing 2. The protective shielding housing 2 is provided with two corner buckling grooves 21. The corner buckling grooves 21 facilitate the operation of the protective shielding housing 2. By restricting the two externally attached limiting plates 4 on the outer side of the protective shielding housing 2, the position of the protective shielding housing 2 is restricted.

[0024] The base plate 11 is provided with a telescopic installation groove 111. The externally attached limiting plate 4 is slidably connected in the telescopic installation groove 111. The connection between the externally attached limiting plate 4 and the telescopic installation groove 111 facilitates the use of the externally attached limiting plate 4. And by providing the telescopic installation groove 111 on the base plate 11, it does not affect the main body of the pump body 1.

[0025] A limiting spring 5 is fixedly connected in the telescopic installation groove 111. One end of the limiting spring 5 is fixedly connected to the externally attached limiting plate 4. By restricting the two externally attached limiting plates 4 on the outer side of the protective shielding housing 2, the limiting spring 5 exerts a resistance on the externally attached limiting plate 4, thereby stably restricting the position of the externally attached limiting plate 4 on the protective shielding housing 2.

[0026] The working principle and usage process of the present utility model: Two base plates 11 are fixedly connected to the top of the pump body 1.

And a winding film is arranged at the connecting part of the connecting hidden lifting rope 3 and the lifting ring 12. The connecting hidden lifting rope 3 is fixed in advance and protected by the winding film, which brings convenience during the subsequent process of shifting the sewage pump. By setting the two ends of the connecting hidden lifting rope 3 to be respectively fixedly connected to the two lifting rings 12, the pump body 1 is provided with an internal concave cavity 13. The connecting hidden lifting rope 3 is located in the internal concave cavity 13. And a protective shielding housing 2 is inserted into the internal concave cavity 13. The protective shielding housing 2 is hidden in the internal concave cavity 13 to reduce the occupied volume and provide protection. During use, the position of the externally attached limiting plate 4 can be slid, and the externally attached limiting plate 4 is moved away from the outer side of the protective shielding housing 2, so that the connecting hidden lifting rope 3 located in the internal concave cavity 13 can be extended, thereby facilitating the connection with the hoisting equipment.
