Description

Technical Field

[0001] The utility model relates to a compact coupling installation structure for a submersible sewage pump. Background Art

[0002] For the existing coupling installation structure of a submersible sewage pump, refer to Figure 1 , 21 outlet pipe seat, 22 steel pipe, 23 submersible sewage pump, 24 coupling frame. For the structure of the coupling frame, refer to Figure 2 , 501 upper plate, 502 hanging plate, 503 pump body connection surface, 504 coupling pipe orifice surface, 505 coupling fitting inclined surface, 506 coupling fitting plate, 507 semi-circular hole, 508 threaded hole. During installation, install the coupling frame on the pump body, lift the pump, insert the semi-circular hole of the coupling frame into the steel pipe, and slide the pump down along the steel pipe to the bottom, then fasten the coupling frame together with the pump and the outlet pipe seat. When the pump needs to be repaired, just lift the pump upward, and the coupling frame together with the pump will be disconnected from the outlet pipe seat. However, the overall lateral dimension of the pump together with the coupling device is relatively large, and it is difficult to install under the limit installation space. There is an urgent need to design a compact coupling installation structure to solve the above problems. Summary of the Invention

[0003] Aiming at the above problems existing in the prior art, the utility model provides a compact coupling installation structure for a submersible sewage pump. The utility model designs a compact coupling installation structure for a submersible sewage pump, which includes an outlet pipe seat, a channel steel, a submersible sewage pump, and a coupling frame. The coupling frame is characterized in that it is composed of an upper plate, a hanging plate, and a guiding plate. There is a through hole starting from the middle of the hanging plate, and a pump body connection surface and a coupling pipe orifice surface are arranged on both sides of the hanging plate. The upper end of the hanging plate is connected with an upper plate, and the upper plate is bent outward. The top end of the upper plate is connected with a coupling fitting plate, and a coupling fitting inclined surface is arranged on the inner side surface at the lower end of the coupling fitting plate. Guiding plates are connected to both sides of the upper plate. The upper plate is perpendicularly arranged with the hanging plate. Threaded holes are arranged on the hanging plate, and bolts are arranged in the threaded holes to connect the pump body. The pump body connection surface of the coupling frame and the pump body flange are connected by bolts. There is a 3-mm gap left unilaterally between the guiding plate and the concave opening of the channel steel. The advantages of the utility model are as follows: The guiding position of the coupling frame is changed from the front part of the upper plate of the coupling frame to both sides of the upper plate, and the guiding is reconfigured with the channel steel. At the same time, the lateral dimension of the outlet pipe seat is modified. After the double transformation and innovation, the overall lateral dimension of the coupling device is shortened, which is suitable for coupling installation under the limit space.

[0011] The following further details the specific embodiments of the present utility model with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the present utility model. Although the present utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative and do not limit the scope of the present utility model.

[0012] A compact structure for coupling installation of a submersible sewage pump in the figure includes a water outlet pipe seat 1, a channel steel 2, a submersible sewage pump 3, and a coupling frame 4. It is characterized in that the coupling frame is composed of an upper plate 401, a hanging plate 402, and a guiding plate 407. A through hole 409 starts in the middle of the hanging plate 402. A pump body connection surface 403 and a coupling pipe orifice surface 404 are arranged on both sides of the hanging plate 402. The upper end of the hanging plate 402 is connected to the upper plate 401. The upper plate 401 bends outward. The top end of the upper plate 401 is connected to a coupling fitting plate 406. A coupling fitting inclined surface 405 is arranged on the inner side surface at the lower end of the coupling fitting plate 406. Guiding plates 407 are connected to both side edges of the upper plate 401. The upper plate is perpendicular to the hanging plate. Threaded holes 408 are arranged on the hanging plate, and bolts are arranged in the threaded holes to connect the pump body. The pump body connection surface of the coupling frame and the pump body flange are connected by bolts. A 3-mm gap is left unilaterally between the guiding plate and the concave notch of the channel steel.

[0013] During installation, install the coupling frame onto the pump body, lift the pump, insert the guide plate on the coupling frame into the notch of the channel steel, slide the pump down along the channel steel to the bottom, and fasten the coupling frame together with the pump and the water outlet pipe seat. When the pump needs to be repaired, just lift the pump upward, and the coupling frame will be disengaged from the pump and the water outlet pipe seat. This installation method is worry-free, labor-saving and time-saving.

[0014] For the comparison of the transverse dimensions of the coupling frame, refer to Figure 11 , and it can be found that the upper plate of the coupling frame with the new structure is shorter than that of the original structure. Due to the structural improvement of the coupling frame, the transverse dimension of the water outlet pipe seat can be shortened. For the comparison, refer to Figure 12 , and it can be found that the water outlet pipe seat with the new structure is shorter than that of the original structure.

[0015] For the comparison of the transverse dimensions of the coupling device, refer to Figure 13 , and it can be found that the coupling device with the new structure is shorter than that of the original structure. After the innovation of the coupling frame structure, the transverse dimension of the water outlet pipe seat is innovatively shortened. After the innovation of the two parts, the transverse dimension of the coupling device is effectively shortened, which is suitable for installation in limited spaces.
