Warning board device for river dredging

Abstract

The invention belongs to the technical field of riverway treatment, and discloses a warning board device for riverway dredging, which comprises a base, reinforcing mechanisms are arranged at four corners of the base, two groups of height adjusting mechanisms are arranged on the outer wall of the top of the base, and adjusting blocks are fixed on the outer walls of the tops of the height adjustingmechanisms through bolts. The adjusting block is rotationally connected with a fixing frame through an adjusting shaft, a warning plate is clamped to the inner wall of the fixing frame, a cleaning mechanism is arranged on the outer wall of the fixing frame, the cleaning mechanism comprises two cleaning rollers and a rolling gear, cleaning brushes making contact with the warning plate are arrangedon the outer side walls of the cleaning rollers, and the cleaning rollers are fixedly connected with the rolling gear through cleaning shafts; the outer walls of the tops of the two cleaning shafts are jointly and rotationally connected with the same support, the inner wall of the support is rotationally connected with a driving device, the cleaning mechanism of the device can effectively and automatically clean floating dust and sludge blocks on the warning board, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of river course management, in particular to a warning sign device used for river course dredging. Background technique [0002] River dredging generally refers to the treatment of rivers, which belongs to water conservancy projects. At present, there are many ways to dredge rivers: the most common way is to use mechanical equipment to blow and stir the silt deposited on the bottom of the river into turbid water, and flow with the river. So as to play a role in dredging. However, this method has high requirements for water flow speed, and this method of dredging is a temporary solution, not a permanent solution. It only transports the silt at a certain position to the downstream, and the silt itself has not been reduced. The accumulation of low places leads to the accumulation of silt, and when the river is dredged, warning signs are required to warn passing pedestrians and vehicles. [0003] Because warni...

However, this method has high requirements for water flow speed, and this method of dredging is a temporary solution, not a permanent solution. It only transports the silt at a certain position to the downstream, and the silt itself has not been reduced. The accumulation of low places leads to the accumulation of silt, and when dredging the river, warning signs are required to warn passing pedestrians and vehicles

[0003] Because warning signs are easily polluted by floating dust, silt, etc., they need to be cleaned. General warning signs lack cleaning devices, and for some remote river treatment, warnings need all-weather warnings, and construction is carried out during the day. For For warnings during non-construction hours, if arranging personnel to manually clear the warning signs, it will take up manpower and be extremely inconvenient
