Description

Technical Field

[0001] The invention relates to the technical field of prefabricated pump stations, and in particular to a stable and reliable integrated prefabricated pump station. Background Art

[0002] In the existing integrated prefabricated pump stations, the water inlet is mostly one of the two forms of basket grilles or crushing machine grilles. At present, crushing machine grilles are more commonly used. When the crushing machine grille is used, when the crushing machine grille is under maintenance, the crushing machine grille is lifted out of the integrated prefabricated pump station, and there is no grille at the water inlet of the integrated prefabricated pump. Foreign objects in the water inlet pipe or foreign objects in the sewage pipe network directly enter the integrated prefabricated pump station. On the one hand, the foreign objects entering can easily cause the submersible pump in the integrated prefabricated pump to be blocked, increasing the workload of cleaning the submersible pump. On the other hand, it increases the risk of the submersible pump being blocked and burned by foreign objects; if the customer needs to transform the crushing machine grille into a basket grille later, it is necessary to cut off the crushing grille bracket and reinstall the basket grille bracket, which increases the cost and cycle of the transformation. Summary of the invention

The water pump is connected to the outlet pipe arranged on the barrel body through a pipeline.

[0035] The base 1 is a conical cylinder structure with a small top and a large bottom. The outer edge of the lower end of the base is provided with a horizontally arranged annular ring plate, which has good fixing stability; the cylinder bottom 101 in the base is suspended in the base, which is stable and reliable and not easy to be damaged.

[0036] A fixed grille bracket is provided in the barrel body 2; the grille bracket is arranged corresponding to the water inlet pipe to facilitate crushing or filtering foreign matter; the grille bracket includes a guide channel 10 corresponding to the inner port of the water inlet pipe and a grille mounting frame 11 for placing the crushing machine grille or the basket grille, and the crushing machine grille or the basket grille is movably arranged in the grille mounting frame, that is, the crushing machine grille or the basket grille can be taken out and arranged in the grille mounting frame; one side of the grille mounting frame is connected to the guide channel, and the other side or other side of the guide channel is provided with a through hole connected to the inner cavity of the barrel body.

[0037] The crushing machine grille is placed in the grille installation frame; when the crushing machine grille is under maintenance, the crushing machine grille is taken out from the grille installation frame, and the basket grille is put in as a temporary replacement, which effectively prevents foreign matter from entering the prefabricated pump station during maintenance and provides better protection for the submersible pump inside the prefabricated pump.

[0038] Or when the customer needs to transform the crushing grid into a basket grid, the basket grid can be directly put in, reducing the transformation cost and cycle.

[0039] The top cover of the barrel body is provided with a grille inlet and outlet 7 and an inspection port 6, an openable grille inspection cover 5 is provided corresponding to the grille inlet and outlet, an openable inspection cover 4 is provided corresponding to the inspection port, and an inspection ladder 8 is provided corresponding to the inspection port in the barrel body to facilitate maintenance personnel to enter for maintenance.

[0040] The grille installation frame is located directly below the grille inlet and outlet. The tops of the crushing grille and the basket grille are both provided with hanging rods 1304 or hanging ears to facilitate the installation or removal of the crushing grille and the basket grille.

[0041] An opening for taking and placing the grille is arranged at the upper end of the grille installation frame, and an inclined guide plate inclined outward is arranged at the edge of the upper opening of the grille installation frame to facilitate taking and placing the grille.

[0042] The grille mounting frame 11, the crushing machine grille and the basket grille 13 are all square structures; preferably, the grille mounting frame is a square box with an open upper end, and the square grille structure is not easy to shake during use when placed in the grille mounting frame, and is stable and reliable; one side of the square box is provided with a through hole connected to the inner end of the guide channel, and the other side of the square box is provided with a through hole connected to the inner cavity of the barrel body; the basket grille includes a square grille frame 1301, and a grille 1302 is provided on the grille frame, and the grille is arranged corresponding to the through hole inside the grille mounting frame.

[0043] A guide rod 9 is provided between the grille support and the grille inlet and outlet, and an open positioning clamp ring 1303 is provided on the grille to match the guide rod. The grille can be moved up and down stably, and the grille is limited in position in the grille support by the clamp ring and is not easy to shake.

[0044] The lower end of the guide rod 9 is fixedly connected to the upper part of the guide channel of the grille bracket, and the upper end of the guide rod is fixedly connected to the top of the barrel body through the fixed bracket 12. The guide rods are a pair of vertically arranged side by side, and the fixed brackets are arranged at the top of the barrel body corresponding to the grille inlet and outlet, and the structure is compact. An annular groove is provided on the top of the guide rod to facilitate the removal of the opening positioning clamp on the grille, thereby facilitating the grille to be separated from the pump station.

[0045] The guide channel 10 is a channel with a large outer port and a small inner port. The outer port of the guide channel is connected to the inner wall of the barrel body, and the inner port of the guide channel is connected to the grille mounting frame. The guide channel is provided with a water outlet connected to the inner cavity of the barrel body to improve the processing efficiency of the pump station.

[0046] Preferably, the guide channel 10 includes an upper plate and a lower plate and two side plates arranged between the upper plate and the lower plate, the upper plate and the lower plate are horizontal plates, the two side plates are vertical plates, the outer edges of the upper plate and the lower plate are arc-shaped edges adapted to the inner wall of the barrel body, and the outer edges of the side plates are provided with flanges for fixing to the inner wall of the barrel body, which are reliably fixed; the water inlet is arranged on the upper plate and the upper part of the side plate, and is not easy to be blocked.

[0047] When the crushing machine grid is under maintenance, the basket grid can be used as a temporary replacement, or when the customer needs to transform the crushing grid into a basket grid, they only need to directly purchase the basket grid with the corresponding water inlet diameter. It provides better protection for the submersible pump inside the integrated prefabricated pump, reduces the frequency and cost of cleaning the submersible pump, greatly reduces the risk of the submersible pump being blocked by foreign objects and burned, greatly delays the service life of the submersible pump, and improves the stability and reliability of the pump station.
