Description

Technical Field

[0001] The utility model relates to the field of pump stations, and more specifically to a pump station flood prevention system based on a lifting type. Background Art

[0002] Water storage pumping stations and water supply pumping stations are generally installed in basements or closed rooms. When water leaks occur in the pipes, seals, etc. of the pumping stations, the water pumps, electrical cabinets and other equipment of the pumping stations are often flooded and damaged, causing considerable economic losses and water supply interruptions to the owners.

[0003] Simply setting up drainage mechanisms such as floor drains will not be able to drain the accumulated water in time when there is too much water, which will cause water to get on the surface of the water pump, causing corrosion to the pump body. In severe cases, it will cause a short circuit in the water pump circuit, resulting in great economic losses. Utility Model Content

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0026] See also Figure 1-3In the utility model, a pump station flood prevention system based on a lifting type includes a control cabinet 1 fixedly installed above a pump room, wherein a collection tank is provided inside the pump room, a lifting platform 2 is fixedly installed on the inner bottom wall of the collection tank, a pump body 3 of a pump station is fixedly installed on the top of the lifting platform 2, a float level gauge 4 is fixedly installed inside the pump room, a submersible sewage pump 5 is fixedly installed on the inner bottom wall of the collection tank, a lead-out pipe 6 is fixedly installed at the water outlet of the submersible sewage pump 5, and the other end of the lead-out pipe 6 is connected to a nearby rainwater well, and the float level gauge 4, the submersible sewage pump 5 and the lifting platform 2 are all electrically connected to the control cabinet 1;

[0027] The input and output ends of the pump station body 3 are fixedly installed with connecting parts 7, and the connecting part 7 includes a movable tube 71 fixed to the pump station body 3 through a flange, and a sleeve 72 slidably connected to the movable tube 71 is sleeved on the movable tube 71. A sealing piston 73 is fixedly installed at one end of the movable tube 71 located inside the sleeve 72, and the sealing piston 73 is in close contact with the inner wall of the sleeve 72.

[0028] In the utility model, when water accumulates inside the pump room due to pipe rupture or water seepage, since the collection tank is installed at the lowest position of the pump room, the accumulated water is mostly collected inside the collection tank, and then spreads upward. When the float level gauge 4 detects the accumulated water, it transmits the detection data to the control cabinet 1, and then the control cabinet 1 controls the lifting platform 2 and the submersible sewage pump 5 to be powered on, and the lifting platform 2 rises to lift the height of the pump station pump body 3 to prevent the pump station pump body 3 from being submerged in the accumulated water and causing rust or short circuit damage. At the same time, the submersible sewage pump 5 continues to discharge the accumulated water to the outside, and introduces the discharged accumulated water into the nearby rainwater well through the outlet pipe 6. When the water level drops to a height that the float level gauge 4 cannot detect, the lifting platform 2 is reset, and the submersible sewage pump 5 still works for five to ten minutes and then stops, until the float level gauge 4 detects the water level and works again, which can prevent the pump station equipment from being submerged in the accumulated water, protect the main pump body equipment in the pump station, and make the use of the pump station safer and more reliable.

[0029] Among them, since the pipeline connection of the pump station pump body 3 is actually connected by metal pipes, the lifting and lowering of the pump station pump body 3 is restricted by the metal pipes. This solution connects the pump station pump body 3 and other equipment through the connecting piece 7. During the lifting and lowering process of the pump station pump body 3, the movable pipe 71 moves with the pump station pump body 3 and maintains the connection between the movable pipe 71 and the sleeve 72, so that the lifting and lowering of the pump station pump body 3 is less restricted. At the same time, the sealing piston 73 seals the gap between the movable pipe 71 and the sleeve 72 to prevent leakage, and can maintain the connection state of the pipeline when lifting the pump station pump body 3, avoiding deformation or overall rupture of the connecting pipeline caused by strong lifting.

[0030] See also Figure 1 , wherein: an exhaust fan 8 is installed on the pump room, and the interior of the pump room is connected to the outside through the exhaust fan 8.

[0031] In the utility model, the ventilation state of the pump room is maintained by the exhaust fan 8, so as to avoid excessive moisture inside the pump room from aggravating the corrosion of the equipment and maintain a dry state.

[0032] See also Figure 1 and Figure 2 , wherein: a shaped metal sheet 74 is fixedly mounted on the movable tube 71 , the shaped metal sheet 74 is located on one side of the sealing piston 73 and contacts the sealing piston 73 , the diameter of the shaped metal sheet 74 is slightly smaller than the sealing piston 73 , and does not contact the inner wall of the sleeve 72 .

[0033] In the utility model, the sealing piston 73 is supported by the shaped metal sheet 74. When the internal pressure of the sleeve 72 and the movable tube 71 is high, the structural shape of the sealing piston 73 can be maintained to ensure the sealing effect.

[0034] See also Figure 1 , wherein: the top edge of the installation collection tank is inclined, and the diameter of the installation collection tank gradually decreases from top to bottom.

[0035] In the utility model, the inclined installation collection trough can facilitate the inflow of accumulated water and facilitate the discharge of accumulated water by the submersible sewage pump 5.

[0036] See also Figure 1 and Figure 2 , wherein: the shape of the sleeve 72 is one of an L-shape and a U-shape.

[0037] In the present invention, the special-shaped sleeve 72 can be easily connected to other equipment of the pump station, and is convenient for connection, installation and use.

[0038] See also Figure 3 , wherein: an alarm module 11 is arranged in the control cabinet 1.

[0039] When the control cabinet 1 receives the detection data of the float level meter 4, the control alarm module 11 is controlled to alarm, and the alarm modes include sound and light alarm, SMS alarm, telephone alarm, etc.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
