Background technique

Prefabricated pumping station is an integrated product integrating submersible pump, pumping station equipment, control system, etc. The characteristics of the prefabricated pumping station are flexible and flexible, the construction period of the pumping station is extremely short, and the installation is simple. At present, it has become a new development trend of pump station construction in the domestic municipal industry. As the application technology of integrated prefabricated pumping stations in my country is becoming more and more mature and developing towards large-scale, there are already integrated prefabricated pumping stations with a diameter of 3800mm.

On the basis of the traditional pumping station, an integrated pumping station has appeared. The integrated prefabricated pumping station is often used in places that cannot rely on gravity to discharge sewage by itself. The sewage tank collects waste water below the water level and is far away from the municipal sewage pipe network. Wastewater discharged from sanitation facilities is transported to the sewage pipe network with the help of sewage pumps. It is mainly used in the construction of sponge cities such as flood control and drainage, river restoration, black and odorous water treatment, and rainwater collection and utilization. However, the integrated pumping station with large displacement has also encountered bottlenecks. The large-displacement rainwater pumping station is in the urban drainage system. The water in the pipeline is often mixed with rain and sewage, mixed with some garbage, sticks and other sundries, and enters the pump station together, often blocking the water inlet of the submersible pump, affecting the normal operation of the pump in the integrated pump station.

At this time, the pump group can be stopped, and the thin push rod is reset. When inserting the water inlet filter port of the fixed plate, until the thin push rod completely penetrates the water inlet filter port, the garbage and impurities inside the water inlet filter port are exported to the outside world, and then the water inlet filter port is dredged, and the composite pump restores the pumping capacity.

The interface between the water pipe and the connecting pipe sleeve prevents external organisms from entering the interior of the composite pump and interfering with the internal structure of the pumping pump group.

5. The sliding plug slides out of the connecting pipe sleeve under the action of water pressure, but under the action of the notch, if the sliding plug does not completely slide out of the connecting pipe sleeve, it can also open the connection between the connecting pipe sleeve and the water outlet pipe, so as to avoid the occurrence of sliding plugs. After the connection sleeve is completely slid out, the sliding plug and the end of the connection sleeve are misaligned, so that the sliding plug cannot be retracted into the inner wall of the connection sleeve.

6. The device uses two sets of pumping pump sets for pumping, which has the characteristics of high symmetry. The pumping pump set will vibrate when it is working. Using the symmetrical characteristics of the upper and lower sets of pumping pump sets, you can install the symmetrical mounting plate to a certain extent. The vibrations on both sides are offset, thereby increasing the stability of the composite water pump during operation and improving the pumping efficiency.

The connecting pipe sleeve 78 slides out under the action, but under the action of the notch, the sliding plug 77 does not completely slide out of the connecting pipe sleeve 78 and can also open the connection between the connecting pipe sleeve 78 and the water outlet pipe 2, so the suction pump group 41 stops. After the water is pumped, the sliding plug 77 can be pulled back into the connecting tube sleeve 78 by the thin rod head 76 under the action of the tension spring 74 , blocking the outlet of the guide tube 7 and preventing external organisms from entering the interior of the composite water pump 4 .

The embodiments of the present invention have been described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific embodiments, which are merely illustrative rather than restrictive. Under the inspiration of the present invention, without departing from the scope of protection of the present invention and the claims, many forms can be made, which all belong to the protection of the present invention.
