In the figure: 1. a communicating box; 2. a flowmeter body; 3. a sealing plate; 4. a cover plate; 5. a support rod; 6. a rotating column; 7. a blade; 8. a fixing plate; 9. a filter screen; 10. a rotating rod; 11. a brush.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, an anti-blocking flow meter in this embodiment includes a communication box 1 and a flow meter body 2 fixedly installed at the top of the communication box 1, a sealing plate 3 is embedded at the top of the communication box 1, a cover plate 4 is fixedly connected to the top of the sealing plate 3, the cover plate 4 covers the sealing plate 3, a support rod 5 and a fixing plate 8 are fixedly connected to the bottom of the sealing plate 3, the fixing plate 8 is in an inclined L shape, the width of the fixing plate 8 is equal to the width of the inner side of the communication box 1, one side of the fixing plate 8 is attached to the left side wall of a communication box 10, a filter screen 9 is arranged on the fixing plate 8, and an anti-blocking component is arranged on the support rod 5.

In this structure, can accomplish the clearance to filter screen 9 through preventing stifled subassembly to realize preventing stifled effect, and with apron 4 separation, thereby can clear up preventing stifled subassembly separation.

Wherein in order to realize the effect of preventing blocking, prevent blocking up the drive assembly of installation on the subassembly includes bracing piece 5, drive assembly includes the column 6 of the one end transmission connection of bracing piece 5, four blade 7 of column 6 outside fixed connection, the one end fixed connection that column 6 is relative with bull stick 10, drive assembly's one end is connected with bull stick 10 between fixed plate 8, bull stick 10 outside fixedly connected with brush 11, one side of brush 11 closely pastes with filter screen 9, the length of brush 11 is greater than the diameter of filter screen 9.
