Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a coupling frame with a guided submersible sewage pump coupling device. Background Art

[0002] Submersible sewage pumps are short for submersible sewage pumps. They are primarily used in municipal engineering, building construction, industrial wastewater, and sewage treatment applications to discharge sewage, wastewater, and rainwater containing solids and long fibers. Two common installation methods are coupling and mobile. The coupling installation is suitable for submersible sewage pumps of various specifications and is the most common installation method. The coupling installation connects the pump to the pipeline via a coupling bracket, making it easy to disconnect the pump from the outlet pipeline and allowing the pump to be lifted using a lifting device for maintenance.

[0003] However, although the existing submersible sewage pump coupling device facilitates the installation and maintenance of the submersible sewage pump, the sealing gasket and the outlet pipe seat may collide during the coupling process, causing the sealing gasket to flanging and causing leakage. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a coupling frame with a guided submersible sewage pump coupling device, which can prevent leakage problems during the coupling installation of the submersible sewage pump.

[0005] A coupling frame with a guided submersible sewage pump coupling device, the coupling frame comprising a positioning portion and a coupling portion, the positioning portion being fixedly connected to the upper end of the coupling portion and provided with a positioning slot, the axis of the positioning slot being perpendicular to the cross-section of the positioning portion, the positioning slot being used to fix the coupling frame on the outlet pipe seat of the submersible sewage pump; the coupling portion being provided with an outlet pipe slot, the coupling frame further comprising a sealing gasket, the sealing gasket being clamped on the outlet pipe slot, and a guide block being further provided on the side of the lower end of the coupling portion close to the outlet pipe, the guide block being in contact with the side wall of the outlet pipe seat when in use, thereby ensuring that the sealing gasket will not fall off due to collision with the outlet pipe seat during the lowering process of the coupling frame.

[0006] Furthermore, the guide block is provided with a guide slope, which is a slope that deviates from the vertical line and extends from top to bottom toward one side of the water outlet pipe seat.

[0007] Furthermore, two coupling claws are fixedly connected to both sides of the coupling portion.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The coupling frame of the guided submersible sewage pump coupling device described in the utility model adopts a coupling guide structure at the bottom, so that the coupling frame and the water outlet pipe seat avoid collision between the sealing gasket and the water outlet pipe seat during the coupling process, and prevent leakage caused by flanging of the sealing gasket.

[0016] In the following description, detailed examples are provided to provide a deeper understanding of the present invention. Obviously, the described examples are only a portion of the present invention, not all of it. It should be understood that the specific examples are intended only to illustrate the present invention and are not intended to limit the present invention.

[0017] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0018] Please refer to Figure 1-2 As shown, a coupling frame with a guided submersible sewage pump coupling device, the coupling frame includes a positioning portion 1 and a coupling portion 2, the positioning portion 1 is fixedly connected to the upper end of the coupling portion 1 and is provided with a positioning slot 11, the axis of the positioning slot 11 is perpendicular to the cross section of the positioning portion 1, and the positioning slot 11 is used to fix the coupling frame to the outlet pipe seat of the submersible sewage pump. Please refer to Figure 3-5The coupling part 2 is provided with a water outlet pipe slot 21, and the coupling frame also includes an annular sealing gasket 3, which is clamped on the water outlet pipe slot 21. A guide block 22 is also provided on the side of the lower end of the coupling part 2 close to the water outlet pipe. The guide block 22 will fit with the side wall of the water outlet pipe seat when in use, which can ensure that the sealing gasket 3 will not fall off due to collision with the water outlet pipe seat during the lowering process of the coupling frame.

[0019] Preferably, the guide block 22 is provided with a guide slope 221, which is an inclined surface extending downward from the vertical line toward the side of the water outlet pipe seat. The guide slope 221 can further ensure that the sealing gasket 3 will not be knocked off during the lowering of the coupling frame.

[0020] In the present invention, two coupling claws 23 are fixedly connected to both sides of the coupling portion 2. The two coupling claws 23 can move the fulcrum of the coupling frame downward, thereby improving the stability of the coupling frame during installation and use.

[0021] Compared to the prior art, the coupling frame of the guided submersible sewage pump coupling device described in this utility model utilizes a coupling guide structure at the bottom. This prevents the sealing gasket from colliding with the outlet pipe seat during coupling, thus preventing leakage caused by the sealing gasket flanging. Furthermore, the coupling frame of this utility model utilizes a direct casting process, which simplifies processing and reduces costs.

[0022] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
