Safe and energy-saving digital hydrological measurement and control device

Abstract

The invention discloses a safe energy-saving type digital hydrological measuring and control device. The safe energy-saving type digital hydrological measuring and control device comprises a rectangular main travelling frame, wherein travelling pulleys are arranged at two ends of the top of the main travelling frame; an auxiliary travelling frame is rotationally connected below the middle of the bottom of the main travelling frame; a hanging box is suspended below two ends of the auxiliary travelling frame through slings; a flow velocity meter is suspended below the hanging box through a sling; a power supply, a hanging box lifting winch and a flow velocity meter lifting winch are arranged in the hanging box; an electric telescopic push rod is connected between the left end of the auxiliary travelling frame and the left end of the bottom of the main travelling frame, and a sensor is arranged in the middle of the bottom of the auxiliary travelling frame and connected with a push rod driving controller which is connected with the electronic telescopic push rod. The safe energy-saving type digital hydrological measuring and control device has the beneficial effects as follows: two ends of the hanging box always keep basically horizontal in an operating process, a comfortable working environment is provided for an operator in the hanging box, further, the hanging box is controlled to be kept in a proper height, so that the safety is improved, and the measurement accuracy is guaranteed.

Description

technical field [0001] The invention relates to a safe and energy-saving digital hydrological measurement and control device. Background technique [0002] Hanging boxes have been widely used in the hydrological tests of the Yellow River, and they are increasingly playing an important role, especially in low-water regulation tests, and their advantages are more prominent. The hanging box can not only complete the flow test, but also complete the sediment test, which cannot be replaced by the current meter for crossing the river. Due to the existence of the suspension box, the bouncing of the cableway is much smaller than that of the current meter crossing the river cable, which improves the depth measurement accuracy; in addition, the tightness of the circulating cable will not have any impact on the water depth data, which is also the reason why the current meter crossing the river cable The hanging box test can be used for low-water tests, while the current-meter crossing...

Problems solved by technology

[0003] When working, the hanging box needs to run on the entire section. During the operation, the hanging box shakes a lot, and it is difficult to maintain a basic level at both ends. Therefore, the working environment for the operators in the hanging box is not comfortable, and the interference to the electronic instrument is relatively large, affecting the accuracy of the measurement
