Dam trash rack solid trash removing device

Abstract

The invention discloses a dam trash rack solid trash removing device. The dam trash rack solid trash removing device comprises a trash removing rake arranged on the water inlet side of a trash rack, acounterweight car arranged above the trash rack in a hinged mode, a traction mechanism for driving the counterweight car to move and turning over the trash removing rake, a base fixedly arranged above the trash rack, rails parallel to the trash rack, and a traveling mechanism which is arranged at the bottom of the traction mechanism and matched with the rails; the counterweight car is in rollingfit with guide rails arranged on the two sides of the trash rack, or with rack strips through guide wheels on the two sides; the trash removing rake inversely covers the trash rack in a C shape, the upper portion of the trash removing rake is hinged to the counterweight car, the lower middle portion of the trash removing rake is connected with a rack turning cable of the traction mechanism, and the trash removing rake is provided with rack teeth inserted into the trash rack; and the traction mechanism comprises a machine frame of which the bottom is fixedly provided with the traveling mechanism, and a spindle arranged on the upper portion of the machine frame, the spindle connected with an output shaft of a speed reducer driven by a motor and wound with a lifting cable and the rake turningcable, the lifting cable is connected with the counterweight car, and the machine frame is provided with a hydraulic rake turning mechanism for enabling the rake turning cable to go up and down. Thedam trash rack solid trash removing device has the characteristics of being simple in structure, stable and reliable in work and high in slag removing efficiency.

Description

technical field [0001] The invention belongs to the technical field of water conservancy equipment, and in particular relates to a dam trash rack solid waste cleaning device with simple structure, stable and reliable operation, high slag cleaning efficiency, energy saving and consumption reduction. Background technique [0002] Energy is the material basis of human activities. In today's world, the development of energy, energy and the environment is a common concern of the whole world and all mankind, and it is also an important issue of my country's social and economic development. As people pay more and more attention to the environment, clean energy has developed rapidly. As a renewable energy source in nature, water energy is repeatedly regenerated along with the hydrological cycle, and one of the main forms of water energy utilization is hydropower generation. In the process of converting water energy into electric energy, hydropower does not undergo chemical changes...

Problems solved by technology

However, because the upper and lower edges of the rake-type cleaning machine are prone to deviation due to changes in water flow and solid dirt blocking, the overall tilt of the rake will cause the up and down operation to be unstable, or even stuck, which seriously causes the steel cable to pull In order to prevent the above situation from happening, the method of increasing the working gap is often adopted. However, as the gap increases, the tooth rake will swing from side to side, which will easily lead to unclean cleaning of the dirt between the bars and even the guide on both sides of the tooth rake. The derailment of the wheel and the steel cable will cause the rake to be stuck or the steel cable will be severely worn, which will affect the working status and service life of the cleaning machine; It will not be made too heavy, so it is difficult for the rake to sink to the effective working position when it encounters the buoyant dirt, and the rake will also tilt due to uneven resistance, which will easily cause the dirt to rise when the claw dirt rises Serious problems such as unclean cleaning, jamming, and even derailment of steel cables; in addition, the existing rake-type cleaning machine realizes cleaning through the upper lifting mechanism. For the setting of multiple trash racks in medium and large hydropower stations, corresponding Setting up multiple cleaning machines to achieve cleaning is not only costly, but also for hydropower stations with relatively little solid waste, most of the time the cleaning machines are in the intermittent working state, and the use efficiency of the cleaning machines is low. high maintenance cost
