Preferably, the utility model discloses a prefabricated pump station of integration still includes axial fan 9, exhaust column and play tuber pipe 10, and axial fan 9 sets up the top at barrel 20. One end of the axial flow fan 9 is connected with the exhaust pipe, and the other end of the axial flow fan 9 is connected with the air outlet pipe 10. The exhaust pipe is positioned in the cylinder body 20, and the air outlet pipe 10 is positioned outside the cylinder body 20.

In this embodiment, axial fan 9 operation for the junction of exhaust column and axial fan 9 forms local vacuum, makes the interior gas of exhaust column move from bottom to top through the barrel that goes out tuber pipe 10 and discharge, because the flow of air, the gas in the barrel 20 is constantly taken out and is diluted, thereby the inside poisonous and harmful gas of barrel 20 is also constantly taken out, improves the interior ventilation effect of barrel, guarantees the maintenance personal's that gets into barrel 20 safety.

Preferably, the bottom end of the extraction duct is located above the liquid level in the bowl 20. So that the toxic and harmful gas above the liquid level is gradually sucked into the exhaust pipe from the bottom outlet of the exhaust pipe and is continuously discharged out of the cylinder body 20.

Preferably, the exhaust pipe comprises an outer pipe and an inner pipe which are coaxially arranged, and the outer pipe is sleeved on the inner pipe. The bottom end of the outer tube is higher than the bottom end of the inner tube.

In the above embodiments, the outer tube and the inner tube are coaxially arranged with a gap therebetween. When the liquid level in the cylinder 20 is between the bottom end of the outer tube and the bottom end of the inner tube, the toxic and harmful gas on the liquid level enters the gap between the inner tube and the outer tube, and is exhausted out of the cylinder 20 under the suction of the axial flow fan 9. When the liquid level in the cylinder 20 is lower than the bottom end of the inner tube, the poisonous and harmful gas on the liquid level enters the inner tube and the gap between the inner tube and the outer tube, and is exhausted out of the cylinder 20 under the suction of the axial flow fan 9. Different liquid level height corresponds different air inlet entries for the poisonous gas homoenergetic on the liquid level is through exhaust column exhaust barrel 20, is favorable to making to sink and is being taken barrel 20 out at any time in the great poisonous and harmful gas of density that is close to the liquid level, and it is lower to solve the liquid level, and when great with the distance of the bottom air inlet entry of exhaust column, the deposit is hardly taken the problem of barrel out at the great poisonous and harmful gas of density of liquid level.

Preferably, the utility model discloses a prefabricated pump station of integration still includes controller 12, poisonous and harmful gas detector 13 and level sensor 2, and controller 12 is connected with poisonous and harmful gas detector 13, axial fan 9, level sensor 2 and immersible pump 3 respectively. The controller 12 is installed outside the cylinder 20, and the poisonous and harmful gas detector 13 and the liquid level sensor 2 are installed inside the cylinder 20. The controller 12 may be an LSK-1JR control cabinet, the liquid level sensor 2 may be a TPL static pressure type (drop-in type) liquid level meter manufactured by beijing tianjian innovative instruments ltd, and the toxic and harmful gas detector 13 may be a TBS type toxic gas detector manufactured by beijing tianjian innovative instruments ltd.

In this embodiment, the liquid level sensor 2 is used for detecting the liquid level in the barrel 20 and sending the liquid level to the controller 12. The poisonous and harmful gas detector 13 is used for detecting the content of poisonous and harmful gas in the barrel 20 and sending the content to the controller 12. The controller 12 is used for receiving the liquid level height sent by the liquid level sensor 2, and when the liquid level height reaches the starting liquid level height of the submersible pump 3, the controller 12 controls the submersible pump 3 to start; when the liquid level drops to the pump stop liquid level, the controller 12 controls the submersible pump 3 to stop. The controller 12 is used for receiving the content of the toxic and harmful gas sent by the toxic and harmful gas detector 13, and when the content of the toxic and harmful gas is larger than a set value, the controller 12 controls the axial flow fan 9 to start. In the present embodiment, by providing the controller 12 and the toxic and harmful gas detector 13, when the content of toxic and harmful gas is greater than a set value, the axial flow fan 9 is automatically turned on, so that the ventilation is performed on the cylinder 20.

Preferably, the check valve 6 is located between the gate valve 7 and the submersible pump 3. During normal work, because the immersible pump opens and stops the number of times more, check valve 6 frequently moves, and it is great to damage the maintenance probability. Closing the gate valve 7 during maintenance facilitates maintenance of the check valve 6 to prevent water from pouring into the barrel 20.

The utility model discloses the working process of the prefabricated pump station of integration as follows:

during normal operation, rain and sewage reach the grating 19 through the water inlet pipe 18 and the opened knife gate valve 17, and impurities in the rain and sewage are crushed or intercepted by the grating 19 and then are gathered into the barrel 20. When the water level reaches the starting liquid level height of the submersible pump 3, the controller 12 controls the submersible pump 3 to operate, rain and sewage are sequentially driven to a required place through the check valve 6 on the water outlet pipe 4, the opened gate valve 7 and a subsequent pipeline by the operation of the submersible pump 3, and therefore lifting and transportation are achieved.

When waiting to overhaul, open top cap 11, axial fan 9 forced draft to according to poisonous and harmful gas detector 13 monitoring gas reaches safety range after, the cat ladder 15 that operating personnel accessible top cap 11 department set up reachs middle maintenance platform 16, looks over operation such as immersible pump 3 and grid 19. If desired, the knife gate valve 17 may be closed to shut off the incoming flow. The operation of the submersible pump 3 and the grille 19 is stopped and the outlet gate valve 7 is closed. The submersible pump 3 or the grating 19 can then be hoisted out and serviced or serviced regularly.

After the submersible pump 3 or the grating 19 is repaired or maintained, the submersible pump 3 or the grating 19 can be lowered to the original position through the pump guide rail 5 or the grating guide rail 14. Then the knife gate valve 17 is opened again, and rain and sewage enter the cylinder 20 again. And after the submersible pump 3 is started, the water outlet gate valve 7 is opened, and the pump station continues to normally operate.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
