Protection device of visual inspection system

Abstract

The invention discloses a protection device of a visual inspection system, which comprises a swing rod. A replacement mechanism is arranged on the surface of one side of the swing rod, the replacementmechanism comprises a cleaning block, the cleaning block is located on the surface of one side of the swing rod, and a fixing rod is fixedly connected to the surface of one side of the cleaning block, and a clamping block are fixedly connected to the surface of one side of the fixing rod. The fixing rod and the clamping block are located on the inner side of the swing rod, the clamping block is connected with a clamping groove, an abutting block is arranged on the surface of the bottom end of the fixing rod, the surface of one side of the abutting block is of an arc-shaped structure, a secondspring is fixedly connected to the surface of the bottom end of the abutting block, and the abutting block and the second spring are both located on the inner side of the swing rod. A reinforcing rodis connected into the swing rod in a penetrating mode. A reinforcing block is fixedly connected to one side surface of the reinforcing rod. The top end surface of the reinforcing block is movably connected to the bottom end surface of the fixing rod; and through the arranged replacement mechanism, after the device is used for a long time, the cleaning block begins to age until the cleaning blockcannot be used, and at the moment, the cleaning block can be simply and conveniently replaced with a new cleaning block.

Description

technical field [0001] The present invention relates to the technical field of devices for visual inspection, in particular to a protection device for a visual inspection system. Background technique [0002] Belt conveyor is an important equipment for mines, power plants, ports and other enterprises to transport coal, ore and other materials. When a belt tearing accident occurs, if it is not detected and stopped in time, the entire belt will be torn, and the strong belt tension will destroy the reducer, motor, frame and other connected equipment, resulting in huge property losses and even personal safety. In order to solve this technical problem, many methods have been tried at home and abroad for belt tear-proof detection, such as: impact detection method to detect the transmission of impact force in the belt medium, and abnormal force of the roller to analyze the abnormal state of the roller. Detection, ultrasonic method to detect ultrasonic wave propagation in belt medi...

Problems solved by technology

However, since the belt conveyor operates outdoors in the open air, its mechanical structure is complex and difficult to change. All kinds of dust, water mist, and large pieces of coal falling from the belt conveyor belt seriously affect the accuracy of the visual inspection system, so how to overcome the harsh environment on site? The impact on visual detection is the key to improving the detection accuracy of belt tearing; as the protection device of a kind of visual detection system disclosed by the invention of CN205643140U, although it effectively reduces the various dusts, The interference of water mist and falling coal on the visual inspection system can also ensure that the camera of the visual inspection system is not corroded by the on-site environment, but it does not solve the problem that the cleaning block will age and lose its efficacy after long-term use. Therefore, we propose a Protection device for visual inspection system
