Description

Technical Field

[0001] The utility model relates to an anti-blocking device for a drainage pump station, belonging to the field of water conservancy facilities. Background Art

[0002] A drainage pump station is an important water conservancy facility that lifts water below the ground to a certain height and then discharges it to maintain the safety and stability of the drainage area. The pumping station includes a pumping pump and a pumping pipe installed on the water inlet end of the pump. The end of the pumping pipe close to the water body is arranged obliquely downward. At the same time, a filter cartridge immersed in the water body is installed on the end of the pumping pipe away from the pump. The filter cartridge plays a role in filtering larger debris during the drainage process. The filter cartridge is generally placed directly in the water body. The silt in the water body will clog the filter cartridge after precipitation. During the drainage process, since the filter cartridge is below the water surface, it is time-consuming and labor-intensive to clean the silt around the filter cartridge. At the same time, when drainage is required, the water body at the filter cartridge is deep, so there are great safety hazards in manually dredging the water. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-clogging device for a drainage pump station to solve the problems raised in the above background technology. The utility model prevents the filter cartridge from being blocked by settled silt, and cleans the silt around the filter cartridge safely and conveniently.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an anti-clogging device for a drainage pump station, comprising a drainage pipe, a filter cartridge installed at one end of the drainage pipe, an end plate installed on the side of the filter cartridge facing away from the drainage pipe, a sleeve sleeve connected and fixed to the drainage pipe, the side of the sleeve facing the end plate is open, the end of the sleeve away from its open end is connected and fixed with a support ear, a side of the support ear is provided with a through hole, a half-thread stud is rotatably installed in the through hole, the end of the half-thread stud close to the end plate is threadedly connected to a straight threaded pipe, one end of the straight threaded pipe is connected and fixed to the end plate, a rectangular groove is provided on the side of the half-thread stud away from the end plate, a rectangular rod is inserted in the rectangular groove, and two handles are symmetrically provided on the end of the rectangular rod outside the rectangular groove.

[0005] Furthermore, both sides of the through hole along the length direction of the half-thread stud are provided with limiting rings, the limiting rings are in sliding contact with the support ears, and the limiting rings are sleeved on the half-thread stud and fixedly connected to the half-thread stud.

[0006] Furthermore, a hollow tube is connected and fixed to a side of the limiting ring away from the support ear, the hollow tube is sleeved on the half-thread stud, and the end of the hollow tube away from the limiting ring is sleeved on the straight threaded tube.

[0007] Furthermore, one end of the straight threaded pipe away from the support ear is connected and fixed with a connecting ear, and the connecting ear is connected and fixed to the end plate.

[0008] Furthermore, a connector is fixedly connected to the middle of one side of the end disc facing the filter cartridge, an end of the connector close to the filter cartridge is fixedly connected to a connector disc, and the connector disc is fixedly connected to the filter cartridge.

[0009] Furthermore, a first flange is fixedly connected to one end of the filter cartridge close to the exhaust pipe, and second flanges are installed at both ends of the exhaust pipe. The second flange of the exhaust pipe close to one end of the filter cartridge is connected to the first flange through multiple sets of bolts.

[0010] Beneficial effects of the utility model:

[0011] 1. When drainage is not required, turn the half-thread stud to increase the length of the half-thread stud in the straight threaded pipe. At this time, the distance between the sleeve and the end plate is reduced until the sleeve contacts the end plate. At this time, the filter cartridge is in the space formed by the sleeve and the end plate, thereby preventing silt from settling into the filter cartridge and clogging it.

[0012] 2. When draining water, twist the half-thread stud to shorten the length of the half-thread stud in the straight thread barrel. At this time, the sleeve and the end plate no longer hide the filter barrel, thereby realizing convenient removal of the blocking components of the filter barrel, so that one end of the rectangular rod is inserted into the rectangular groove, making it convenient to use the rectangular rod to twist the half-thread stud, without the need for personnel to go into the water for dredging, thereby improving safety.

[0013] 3. Install a hollow tube between the support ear and the straight threaded pipe. When the half-thread stud is turned, the half-thread stud drives the hollow tube to rotate through a limit ring. The length of the hollow tube sleeve on the straight threaded pipe increases or decreases with the increase or decrease in the length of the half-thread stud entering the straight threaded pipe. At this time, the hollow tube realizes real-time shielding of the threaded part of the half-thread stud to prevent silt from adhering to the threaded part of the half-thread stud and affecting the threaded connection between the half-thread stud and the straight threaded pipe.

One end of the half-thread stud 11 close to the end plate 5 is threadedly connected to the straight threaded pipe 7, and the connecting ear 6 fixed at one end of the straight threaded pipe 7 is connected and fixed to the end plate 5. When drainage is not required, the half-thread stud 11 is twisted to increase the length of the half-thread stud 11 in the straight threaded pipe 7. At this time, the distance between the sleeve 2 and the end plate 5 is reduced until the sleeve 2 contacts the end plate 5. At this time, the filter cartridge 3 is in the space formed by the sleeve 2 and the end plate 5, thereby preventing silt from settling in the filter cartridge 3 and clogging the filter cartridge 3.

[0026] See Figures 1-6 A rectangular groove 15 is provided on the side of the half-thread stud 11 away from the end plate 5, and a rectangular rod 12 is inserted in the rectangular groove 15. Two handles 13 are symmetrically installed on one end of the rectangular rod 12 outside the rectangular groove 15.
