Charging device and charging method for current measuring trolley

Abstract

The invention provides a charging device for a current measuring trolley. The charging device comprises a charging pile, a charging end, a limiting mechanism and a controller. The charging pile is installed at the position, close to a river bank, of an inhaul cable and comprises a base, an elastic mechanism, a damper, a first installation plate, a second installation plate, a connecting block, a first electrode base and a charging pile electrode; the damper is mounted on the second installation plate, and the extension direction of the damper is consistent with that of the inhaul cable; the first installation plate is mounted on the back surface of the first electrode base through the elastic mechanism; the charging end is installed at the tail end of the current measuring trolley. The limiting mechanism comprises an in-situ switch installed at the tail end of the current measuring trolley and an in-situ check block installed on the base. According to the invention, the requirement of the current measuring trolley on the tension of the inhaul cable can be reduced, the inhaul cable in a loose state can still keep high moving precision and stable moving speed, the inhaul cable is not influenced by environments such as rain and fog, the high-precision butt-joint charging behavior with the charging pile is completed, and the cruising ability of the current measuring trolley is improved.

Description

technical field [0001] The invention relates to the technical field of mobile radar current measurement, in particular to a charging device and a charging method for a current measurement trolley. Background technique [0002] At present, in order to be able to detect parameters such as river flow and velocity in real time, in some areas, a cable is erected above the river, so that the trolley equipped with a flow measuring device moves along the cable, and the flow measurement is completed during the movement. However, the aforementioned method has the following problems: first, the outdoor environment is harsh, especially in some areas, due to geographical location and other reasons, the wind force level above the river is relatively high, and it is easy for the flow measuring trolley to tip over and fall out of the cable. Second, in order to enable the trolley to move smoothly, there are high requirements for the tension and levelness of the cables, which indirectly requi...

Problems solved by technology

However, the aforementioned method has the following problems: First, the outdoor environment is harsh, especially in some areas, due to geographical location and other reasons, the wind force level above the river is relatively high, and it is easy for the flow measuring trolley to tip over the cable

Third, some current-measuring cars need to be charged frequently. In order to reduce the workload of operation and maintenance personnel, charging piles are sometimes installed directly at the ends of the cables so that the current-measuring cars can be charged in time; however, compared with traditional current-measuring cars, The current measuring trolley with the charging pile has higher requirements on the tension of the cable. Once the cable is slightly slack, the current measuring trolley will have a large inclination when it travels near the end of the cable, and it is almost difficult to connect to the charging pile. Perform electrode alignment

However, due to space constraints, it is difficult to build highly stable cables in some areas, and the cables will gradually loosen during use, requiring frequent maintenance by staff

Moreover, when the tension of the cable is insufficient, not only the movement accuracy of the trolley decreases, which eventually leads to charging failure, but also increases the risk of the trolley tipping over
