Description

TECHNICAL FIELD

[0001] The present application relates to a municipal pipe network laying technology, more particularly, it relates to a pump station structure with a drainage device. BACKGROUND

[0002] The integrated prefabricated pump station is arranged at the starting point or the middle of the municipal sewage pipeline, the sewage pipe in the pump station flows into the cylinder of the pump station in a gravity flow mode, and then the sewage is lifted and pressurized by the submersible pump in the cylinder and is transported outward. The prefabricated pump station is an important part of the drainage system, and has the characteristics of continuous water flow, small water flow, large change range and high impurity content in the water. According to the above characteristics of the drainage system, the water inflow of the integrated prefabricated pump station is affected by the elevation of the municipal pipe network, the water inflow, and the impurity content of the pollutants. The sewage may directly flush into the integrated prefabricated pump station well shaft or the submersible pump. Long-term flushing of the sewage rich in pollutants may cause damage to the integrated prefabricated pump station cylinder and the submersible pump, and even the sewage pump may be decoupled and dumped, which affects the drainage effect and service life of the integrated prefabricated pump station.

[0005] The rainwater and sewage of the municipal pipeline network is guided by the inlet pipe to change the inlet flow state, and finally flows into the prefabricated cylinder. The water outlet hole on the shunt head at the lower end of the inlet pipe is oriented away from the submersible sewage pump, so the water flow will not directly scour the submersible sewage pump. The water outlet hole is oriented towards the bottom of the prefabricated cylinder to scour the bottom of the prefabricated cylinder, avoiding sediment accumulation at the bottom of the prefabricated cylinder. The structure of the pump station with a guiding device guides the inlet water of the municipal pipeline network to the bottom of the prefabricated cylinder and offsets the submersible sewage pump, avoiding direct scouring of the submersible sewage pump by the inlet water, while utilizing the potential energy of the inlet water to scour the bottom of the prefabricated cylinder, avoiding the generation of toxic and harmful gases due to sediment accumulation, ensuring the drainage effect of the integrated prefabricated pump station, reducing the failure rate, prolonging the service life, protecting the atmospheric environment around the prefabricated pump station, and ensuring the safety of personnel working in the well.

The submersible sewage pump is lowered by the sliding seat thereon along the lowering rod during installation, and is pulled upward along the lowering rod by the sliding seat during maintenance, which is convenient to operate.

[0008] As a preferred, a coupling joint is connected to the lower end of the drainage pipe, and the outlet of the submersible sewage pump is butted against the end of the coupling joint. The drainage pipe and the submersible sewage pump are connected through the coupling joint, which is convenient and reliable.

The water pump coupling surface and the joint coupling surface are sealingly fitted by being inclined to air, which has good sealing effect.

[0010] As a preferred, a check valve is installed on the drainage pipe. The check valve prevents water hammer phenomenon caused by backflow of water in the drainage pipe, which damages the submersible sewage pump.

[0011] As a preferred, a liquid level meter is installed in the prefabricated cylinder, the liquid level meter is electrically connected to a controller, and the controller is electrically connected to the submersible sewage pump and controls the opening and closing of the submersible sewage pump. The opening and closing of the submersible sewage pump are controlled by the liquid level meter, ensuring that the sewage in the prefabricated cylinder can be discharged in time.

[0013] The pulling rope is connected with the lifting ring to pull the sewage pump to rise and fall. When the sewage pump is lowered to the position, the pulling rope is loosened, and the limiting pin is limited on the lower surface of the limiting plate to prevent the sewage pump from moving upward and separating. When the sewage pump is raised, the pulling rope pulls the lifting ring upward, the connecting seat moves upward in the connecting barrel first, the unlocking rope is pulled, the limiting pin connected with the unlocking rope is pulled, the limiting pin is separated from the limiting plate to realize unlocking, and the pulling rope continues to pull upward to pull the whole sewage pump upward.

[0016] As preferred, the outlet hole is provided with a rotating ball ring at the opening end, a rotating shaft is arranged in the outlet hole, a blade driven by water flow is arranged on the rotating shaft, one end of the rotating shaft is connected with a rotating disc, a sliding block is arranged on the rotating disc in a rotating manner, the sliding block is provided with a sliding hole, the sliding hole is connected with a connecting rod in a sliding manner, and the connecting rod is tightly connected with the ball ring; the rotating disc drives the ball ring to swing up and down.

[0017] The water flow in the water inlet pipe is sometimes large and sometimes small. When the water flow is large, the water flow is far away from the outlet hole, and when the water flow is small, the water flow is close to the outlet hole. Therefore, the position of the silt accumulation is far or close, especially after the silt accumulation in the close position, the large water flow cannot impact and the small water flow cannot move. In the technical scheme, when the water flow in the outlet hole is large, the water flow drives the blade to rotate, so that the rotating shaft rotates, the rotating disc rotates with the rotating shaft, the ball ring swings up and down through the sliding block and the connecting rod, the direction of the hole in the ball ring is adjusted, the water flow impact range is increased, and the impact effect on the silt is improved.

[0018] Compared with the prior art, the beneficial effects of the pump station structure with a drainage device are that the municipal pipe network inflow is drained to the bottom of the prefabricated cylinder and is staggered with the submersible sewage pump, avoiding direct inflow scouring of the submersible sewage pump, and at the same time, the inflow potential energy can be used to scour the bottom of the prefabricated cylinder, avoiding the generation of toxic and harmful gases caused by silt accumulation, ensuring the drainage effect of the integrated prefabricated pump station, reducing the failure rate, prolonging the service life, protecting the atmospheric environment around the prefabricated pump station, and ensuring the life safety of the downhole operation personnel.
