Description

Movable coal-coiling trolley for closed coal yard

Technical Field

The application relates to the technical field of laser coal-coiling, in particular to a movable coal-coiling trolley for a closed coal yard.

Background

The coal-coiling means that a thermal power enterprise monitors the coal storage quantity of the existing coal yard through various technical means. Thermal power enterprises must store a certain amount of coal in order to avoid influencing normal power generation due to insufficient fuel supply or interruption. However, as the storage amount of coal is influenced by factors such as the combustion efficiency of a boiler unit, the size of a coal yard, the local climate or quota power generation amount, etc., if the storage amount of the coal is too large, the fund turnover can be influenced, meanwhile, the coal is stored for a long time, low-temperature oxidation can occur, the quality of the coal is reduced, and even spontaneous combustion of the coal is caused when serious; if the storage is too little, the fire coal of the boiler is suddenly interrupted, so that the boiler cannot normally generate electricity, and serious safety accidents are caused. Therefore, the thermal power enterprises carry out coal coiling, and the metering and economical indexes of the coal consumption of the thermal power enterprises are related.

At present, two modes of coal-coiling are mainly adopted, one mode is manual coal-coiling, the other mode is automatic laser coal-coiling, and the main principle of automatic laser coal-coiling is as follows: the system measures the three-dimensional coordinates of the characteristic points on the coal surface, obtains data such as the volume and the weight of the coal through computer software processing and calculation, and can reproduce the three-dimensional perspective view of the tested pile body. The coal-coiling software of each enterprise is different in size in the software processing, mainly the coal-coiling tools are different

With respect to the above-mentioned related art, the inventors consider that since a coal yard has a plurality of ashes, the laser scanning lens is easily covered with the ashes after operating for a period of time, thereby affecting the accuracy of scanning.
