Problems solved by technology

These two control modes are relatively simple to implement, but there are obvious disadvantages, that is, the preset time interval or liquid level difference should not be too large, otherwise there will be too much debris in front of the grid, and the amount of slag at one time will be too large when removing slag. May cause overload protection of the cleaning machine, and then trip
If the preset time interval or liquid level difference is reduced, the grab bucket of the cleaning machine will remove too little slag each time, resulting in waste of energy and increased equipment loss

Embodiment Construction

[0060] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0061] Such as figure 1 As shown, an automatic control method for a grab-type cleaning machine includes the following steps:

[0062] Step 1: Initialize the grab-type cleaning machine, and obtain the initialization information of the grab-type cleaning machine, and the initialization information includes a first preset condition and a second preset condition;

[0063] Step 2: Control the grab bucket of the grab-type cleaning machine to drop to grab slag, and obtain the action current value Iact of the grab-type cleaning machine;

[0064] Step 3: When the action current value Iact meets the first preset condition and / or the limit switch of the grab of the cleaning machine is triggered, the grab of the grab-type clea...

Abstract

The invention relates to an automatic control method and system for a grab-type cleaning machine. The method includes initializing the grab-type cleaning machine, determining a first preset condition and a second preset condition; controlling the grab-type cleaning The grab bucket of the cleaning machine is lowered to grab slag, and the action current value of the grab type cleaning machine is obtained; when the action current value meets the first preset condition and / or the limit switch of the grab bucket of the cleaning machine is triggered, the grab type cleaning machine is controlled The grab bucket of the cleaning machine rises and transfers the waste residue in the grab bucket to complete a slag grab action; by repeating this, the maximum value of the action current signal for each slag grab action is obtained, until the continuous preset times of each slag grab action If the maximum value of the operating current signal satisfies the second preset condition, the slag grabbing process ends. The automatic control method of the grab-type cleaning machine of the present invention realizes the automatic operation of the grab-type cleaning machine, reduces the no-load loss of the grab-type cleaning machine, saves energy, and truly realizes the grabbing with intelligent control. The work of the bucket cleaner.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic control method and system for a grab-type cleaning machine. Background technique [0002] In the urban rainwater drainage pumping station project, due to the long river and many tributaries, some branches, weeds, garbage, plastic objects, etc. will float from the upper reaches of the river. These objects have a great impact on the operation safety of the pump and are easily entangled. In the impeller of the water pump, the water pump is overloaded or even burned. In the pumping station, the cleaning machine is generally installed in the forebay to fish out the sundries in the river. Large and medium-sized pumping stations use more wire rope grille decontamination machines, rotary grille decontamination machines and mobile grille decontamination machines. Among them, the mobile grille decontamination machine is a kind of mobile rake-type grille, which is t...
