A charging device and charging method for a current measuring car

Abstract

The invention provides a charging device for a current measuring trolley, comprising a charging pile, a charging end, a limit mechanism and a controller; the charging pile is installed near the river bank of the cable, and comprises a base, an elastic mechanism, a damper, a first The mounting plate, the second mounting plate, the connection block, the first electrode seat and the charging pile electrode; the damper is mounted on the second mounting plate and its extension direction is consistent with the extension direction of the cable; the first mounting plate is installed on the first mounting plate by an elastic mechanism The back side of the electrode holder; the charging end is installed at the rear end of the current measuring trolley; the limiting mechanism includes an in-position switch installed at the rear end of the current-measuring trolley and an in-position stopper installed on the base. The present invention can make the current measuring trolley reduce the requirement for the tension of the cable, can still maintain high moving accuracy and stable moving speed on the cable in the relaxed state, and is not affected by the environment such as rain and fog, and can complete the connection with the charging pile. The high-precision docking charging behavior improves the battery life of the current measuring trolley.

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 conduct real-time detection of river flow, flow velocity and other parameters, in some areas, a cable is erected above the river, so that the trolley equipped with the flow measurement device moves along the cable, and the flow measurement is completed during the movement. However, the foregoing methods have the following problems: First, the outdoor environment is harsh, especially in some areas, due to geographical location and other reasons, the wind level above the river is relatively high, and the phenomenon that the current measuring trolley overturns out of the cable is easy to occur. Second, in order to make the trolley move smoothly, there are high requirements for the tension and levelness of the cable, whic...

AI Technical Summary

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
