Quick-change mechanism and method for grabbing mode of trash cleaning robot

Abstract

The invention provides a quick-change mechanism and method for a grabbing mode of a trash cleaning robot. The quick-change mechanism comprises a main beam, a propelling mechanism, a stress supporting assembly, a locking mechanism and a position detecting device, wherein the propelling mechanism and the stress supporting assembly are arranged in the axis direction of the main beam; the locking mechanism and the position detecting device are separately arranged at the two sides of a stress base of the stress supporting assembly; the propelling mechanism drives a switching shaft to be matched with a telescopic arm of a rotary trash cleaning device or a petal type trash cleaning device; the locking mechanism locks the switching shaft; and the position detecting device detects a switching state of the switching shaft. The quick-change mechanism overcomes the problems that an original cleaning and bleaching robot is too long in period and is low in efficiency as a result of manual switching, and has potential safety hazards, and has the characteristics of being simple in structure, quick in switching, high in degree of automation, safe and reliable, and simple and convenient to operate, and switching is in place once.

Description

technical field [0001] The invention belongs to the technical field of automatic switching and loading of cleaning modes, and relates to a quick-change mechanism and method for the grabbing mode of a cleaning robot. Background technique [0002] Trash racks are generally installed at the water turbine inlets of hydropower stations to intercept floating or suspended debris in the river. In order to ensure the smooth flow of the trash racks, the dirt in front of the trash racks needs to be cleaned regularly. However, during the flood season, due to the impact of heavy rain, a large number of floating objects in the upper reaches of the reservoir area will quickly gather in front of the trash rack. In addition to small flexible floating objects such as foam blocks and woven bag plastic debris, the floating objects are usually accompanied by Tree poles, wood and other large floating objects. Large floating objects will not only cause blockage of the trash rack, but also lead to...

AI Technical Summary

Problems solved by technology

[0004] (1) In the actual cleaning process, the speed of pollution is fast, and the rotary cleaning device and the flap type cleaning device need to be replaced frequently. When replacing, one of the devices is located in the replacement area next to the door slot adjacent to the dam surface, and the other device Connected with the cleaning robot, the weight of the rotary cleaning device and the petal cleaning device is calculated in tons. It is necessary to remove the telescopic arm of the connected device of the cleaning robot, and then connect the telescopic arm of another device to the robot. The cycle of manual replacement of the two devices is too long and takes a lot of time. After the replacement, the floating objects in front of the dam will quickly accumulate, which will not achieve the purpose of fast cleaning, affect the cleaning efficiency, and even threaten the trash rack and Safe operation of the unit

[0005] (2) When changing the cleaning method, it is necessary to equip professional licensed personnel for lifting, which requires high technical requirements

[0006] (3) The flexibility of operation is poor, and it is often difficult to ensure that it is in place at one time

[0007] (4) There are many coordinators required at the cleaning site, and there are certain safety risks when lifting
