Description

a drainage device

Technical field

The utility model relates to the technical field of water conservancy engineering, specifically a drainage device.

Background technique

In water conservancy projects, drainage pipes are often used for diversion. The drainage pipes are buried in the ground. Water passes through the drainage pipes from one place and then flows to other locations to achieve water diversion. Through water diversion, rational distribution of water resources is achieved. , Promote the balanced supply of water resources, thereby achieving rational utilization of water resources.

In the prior art, when common water conservancy engineering drainage devices are in use, water is diverted through drainage pipes. However, debris in the water easily enters the drainage pipe along the water flow, causing debris to accumulate in the drainage pipe, thereby causing blockage of the drainage pipe. , affecting the normal use of the drainage pipe. Although some drainage devices used in water conservancy projects can filter and block debris through the grille, and use the impact of the water flow on the fan blades to drive the brush plate to automatically clean the grille, but from the grille The debris cleaned up still remains inside the drainage device and has not been taken out in time. After a period of time, debris will still accumulate and block the grille, thus affecting the filtering effect of the grille.

Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

Please refer to Figures 1 to 4. The present utility model provides a technical solution:

A drainage device includes a square cylinder 1. The inner part of the square cylinder 1 is fixedly connected with a connecting plate 2. Both sides of the connecting plate 2 are fixedly connected with a fixed shaft 3. The outer end of the fixed shaft 3 away from the connecting plate 2 is rotationally connected with The grille 4 has a torsion spring 5 located outside the fixed shaft 3 and between the grille 4 and the connecting plate 2. One end of the torsion spring 5 is fixedly connected to the grille 4, and the other end of the torsion spring 5 is fixed to the connecting plate 2. connection, the torsion of the torsion spring 5 drives the grille 4 to rotate downward, so that the bottom of the grille 4 fits the bottom inside the opening 8; the inside of the square tube 1 and located below the grille 4 is connected to a rotating shaft 6, which rotates A blade 7 is fixedly connected to the outside of the shaft 6, and the blade 7 is slidingly connected to the grid 4. An opening 8 is opened inside the square cylinder 1 on one side away from the blade 7, and the grid 4 passes through the opening 8 and extends to the outside of the square cylinder 1. , the grille 4 is slidingly connected to the opening 8, and the debris filtered by the grille 4 can slide into the collection tank 9 through the opening 8, thus preventing debris from remaining on the grille 4 and facilitating centralized cleaning.

There are five blades 7 in total, and the five blades 7 are equidistantly distributed. The water flow drives the rotating shaft 6 to rotate through the impact blades 7, so that the five blades 7 on the rotating shaft 6 push up the grille 4 in turn, and cooperate with the torsion spring 5 The torque causes the grille 4 to vibrate up and down, preventing impurities from accumulating and retaining, and ensuring the filtering effect of the grille 4; a collection tank 9 is fixedly connected to the outside of the square tube 1 and below the grille 4, and the filtered debris is filtered through the collection tank 9. For centralized collection; a groove 10 is provided on the side of the blade 7 away from the rotating shaft 6, and a roller 11 is rotatably connected to the inside of the groove 10. The roller 11 is used in conjunction with the grid 4, and the roller 11 replaces the blade 7 and the grid 4. direct foundation to prevent jamming and reduce wear; the top of the square cylinder 1 is fixedly connected with a water inlet pipe 12, and the bottom of the square cylinder 1 is fixedly connected with an outlet pipe 13 for water inlet and outlet; the collection tank 9 A water leakage hole 14 is provided at the bottom to drain the remaining water from debris.

Specifically, when using the utility model, first the water flow enters the square cylinder 1 through the water inlet pipe 12. The water flow first passes through the grille 4 and continues to fall.
