The present invention relates to a water flow measuring drifting buoy capable of preventing stranding and resisting impact, which includes: a ball-game table-shaped inflation body with a counterweight capable of drifting autonomously in a direction of a main stream of a water flow, wherein the inflation body is provided with at least two inflation connectors, and the inflation connectors are of a cross-shaped structure formed by connecting in a conical distribution with 4 inflation-stabilizing rods uniformly distributed along a circumferential radiation; the counterweight is 4-10 fan-shaped steel plates arranged annularly in the center of the bottom of the inflation body, and the fan-shaped steel plates are flexibly connected to each other to be able to shake. The ball-game table structure used in the present invention is selected by comparing various shapes to push a buoy to the middle of a river where the water flow is turbulent by using the difference in a water flow speed to prevent the water flow from being stranded where the water flow is slow or being blocked by a rock at a river bank so as not to continue the drift. The steel plate of the cross-shaped structure in the fan-shaped distribution is used, so that the buoy can be turned up and continue to drift once it has fallen to the ground, greatly improving the efficiency of drift.

The present invention relates to a device, a system and a method for monitoring river flow velocity based on differential pressure measurement, comprising: a hull floating on a water surface with an aspect ratio of the hull being greater than one, characterized in that pressure sensors are respectively provided on an upstream face of a front end and a downstream face of a rear end below the floatation line of a ship; an electronic instrument is provided in the hull, and the electronic instrument comprises an acquisition module connected to the two pressure sensors, the acquisition module being connected to a data processing module with a memory, and the data processing module being connected to a satellite positioning module and a wireless communication module. According to the present invention, the flow velocity of water flow is measured based on the difference between the simulated measured upstream face pressure at the bow and the simulated measured downstream face pressure at the stern by an unpowered measuring ship drifting on the water surface. The measured data is transmitted to the data processing center on the ground via the wireless communication network. The present invention enables the flow data to be measured in presence of poor satellite positioning signals and public network signals or no signals, achieving data transmission independent of satellite positioning and public communication networks.
