Abstract

The invention relates to a safety notice board and in particular relates to a safety notice board for a sedimentation basin. The technical problem of the invention is solved by providing a safety notice board for a sedimentation basin and the notice board can attract people and be seen by people and can move. The safety notice board for the sedimentation basin comprises a case body, a rotating shaft, a cover plate, a clamping block, a spring, a rebound block, a first slide rail, first sliding blocks, a rack, a first stroke switch, a supporting rod, a first branch rod and the like, wherein a through hole is formed in the case body; the right side wall of the through hole is provided with the rotating shaft; the cover plate is welded on the rotating shaft; a neck is formed on the right side of the case body; and the neck is placed on the right side of the rotating shaft. People can be attracted and see the notice board when the notice board swings left to right and a trolley is moved by people; and the notice board can be moved.

Description

technical field [0001] The invention relates to a safety reminder board, in particular to a safety reminder board for sedimentation tank construction. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow type according to the direction of water flow in the pool. Considering the flocculation factor in the process of particle settling, it is assumed that the settling velocity of the particles changes at constant acceleration, and the initial settling velocity is set to zero. Considering the flow velocity distribution in the tube, the length of the inclined tube is: -d*tgθ where a is the acceleration of particle sinking velocity change, that is, a=du / dt The above three methods have their own shortcomings. [0003] When constructing the se...
