Embodiment Construction

[0019] see figure 1 , 2 , the oil storage tank cleaning robot system includes a hydraulically driven cleaning robot, a sludge suction system, a high-pressure water pump station, a driving hydraulic pump station, and a PLC-based remote console14. The holes are brought into the oil tank, where they are quickly assembled, and then the operator can remotely control the robot externally through the on-site image and the PLC-based control system. The robot uses the high-pressure water gun 10 with two degrees of freedom of rotation and pitch to cooperate with the lighting 7 and image acquisition equipment 8 to dilute the sludge in the oil tank, and the sludge is accumulated by the push shovel 13, and the sludge suction device transports the sludge to the oil tank. outside the tank. High-pressure water pumping station, hydraulic pumping station and sludge suction device and remote control center 14 are all outside the oil tank, and only robot carries high-pressure water gun 10, ligh...

Abstract

The invention relates to an automatic control system of a robot for cleaning oil sludge, sludge and the like in an oil storage tank, comprising a PLC part, a system for acquiring and displaying images in the tank, a combustible gas monitoring system, a robot walking system, an oil sludge cleaning, an oil sludge sucking control system and other parts. The automatic control system can realize the remote control outside the tank of the robot for cleaning the oil tank, has two modes of automatically cleaning the tank and manually cleaning the tank, and can be used for acquiring image information in the tank and displaying the image information, displaying the concentration of the combustible gas, realizing water jet and push shovel cleaning work, moving the robot and controlling the sucking of the oil sludge. The control system constructed by taking the PLC as the core has high automatic degree, is easy for expansion, librates workers for cleaning the tank from high-intensity work and severe dangerous environments, realizes the safety, the simpleness and reclamation for cleaning the tank and has remarkable social and economic benefits. The automatic control system can be also used for cleaning a finished product oil tank, an autoclave, a cooling tower, a storage tank and the like in the severe dangerous environment.

Description

technical field [0001] The invention relates to an automatic control system of a robot used for cleaning oil sludge and silt in an oil storage tank. Background technique [0002] When the oil tank is storing oil products, especially crude oil, heavy oily components such as mechanical impurities, sand, soil, heavy metal salts, paraffin and asphalt will naturally settle at the bottom of the oil tank due to the difference in specific gravity, forming sludge at the bottom of the oil tank. This part of the mud accumulation reduces the effective capacity of the oil storage tank and seriously affects the storage and transportation production of the oil tank. Therefore, the crude oil storage tank generally needs to be inspected and repaired regularly every 2-3 years and the sludge in the tank is removed. At present, the tank cleaning method of oil storage tanks mainly adopts manual tank cleaning method. In such a harsh and dangerous environment of flammable, explosive and toxic poll...
