A hydrological flood measurement cableway buoy positioning automatic release device

Abstract

The invention provides a hydrological flood monitoring cableway buoy positioning automatic putting device. A buoy storage box is arranged on a fish lead of a hydrological cableway, buoys are overlapped and placed in the box body, a buoy outlet is formed at the lower part of the box body, a buoy guide rod is arranged on the box wall opposite to the outlet, the buoy guide rod is glidingly buckled and connected with one pulling rod of a rotating support frame, the other pulling rod of the rotating support frame is glidingly and buckled with a floating ball guide rod, and the bottom end of the floating ball guide rod is connected with a floating ball. The fish lead falls down in a vertical line position where the buoy needs to be put, the floating ball firstly contacts with water, the fish lead continuously falls down, the floating ball guide rod upwards moves to be linked with the rotating support frame, the pulling rod of the rotating support frame is linked with the buoy guide rod to horizontally move, one buoy arranged at the bottom of the buoy storage box is guided into the water, the fish lead is lifted up, the floating ball descends under the gravity effect, the buoy guide rod is reset by linkage, and the buoys in the buoy storage box fall down under the gravity effect, so that one buoy at the bottom is in a position to be released. Luminous buoys in the same specifications are adopted for flood monitoring at night.

Description

technical field [0001] The invention relates to a river flood hydrological measurement device, in particular to a hydrological flood measurement cableway buoy positioning automatic release device installed on the existing hydrological cableway facilities. Background technique [0002] At present, most of the flood flow tests in natural river hydrological surveys in my country still use the cable current meter method for measurement, that is, the lead fish is hung on the cable, the current meter is installed on the lead fish, and the rotor of the current meter rotates under the action of the water flow. The rotor rotates a certain number of revolutions to connect the contacts once, and transmits the wireless signal to the receiving device on the shore. Through timing and counting the number of revolutions, the speed of the water flow is automatically or manually calculated using the current meter formula. However, since there are more and more aquatic plants and sundries in ri...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing cableway flood measuring instrument, which is affected by the entanglement of aquatic plants, the rotating rotor cannot accurately and quickly measure the water flow velocity, and the buoys on the bridge are difficult to locate the vertical line of the buoy. The present invention provides a hydrological flood measuring cable buoy positioning Automatic delivery device
