Detailed Description
Referring to fig. 1 to 3, the utility model relates to an instant perception's river course section measurement system under water, including three direction measuring device 1. Three-direction measuring device 1 includes tray 11, shell 12, three pressure sensor 13, main control board and power, and shell 12 is installed on tray 11, and pressure sensor 13, main control board and power are installed in shell 12, and the power is pressure sensor 13 and the power supply of main control board. The main control board obtains the parameters of the pressure sensor 13 and transmits the parameters at the same time. The sensing ends of the three pressure sensors 13 are exposed on the surface of the housing 12, and when viewed from the side, the two pressure sensors 13 face the left and right sides, respectively, and one pressure sensor 13 faces vertically upward.
Preferably, each pressure sensor 13 is a digital pressure sensor 13.
Preferably, the three pressure sensors 13 are in the same reference plane. Referring specifically to fig. 2, three pressure sensors 13 are approximately in a straight line in a top view. In use, the vertically upward facing pressure sensor 13 is used to feed back the water depth. The pressure generated by the flowing water can be calculated by the pressure sensors 13 on the left and right sides according to the pressure difference with the previous pressure sensor 13, the pressure sensor 13 on the upstream side can measure the forward river bottom flow speed, and the pressure sensor 13 on the back side can measure the reverse river bottom flow speed. The three-direction measuring device 1 is simple in structure, can measure the water depth and the flow velocity simultaneously, and has strong practicability.
Since the three-directional measuring device 1 needs to be placed under water for a long time, the sealing property is improved. Sealing rings or sealants should be added at the joints between the pressure sensor 13 and the shell 12 and between the shell 12 and the tray 11.
Preferably, the housing 12 is hemispherical or mushroom-shaped, so as to reduce the impact of water flow and avoid shaking; the tray 11 is larger in size than the housing 12, with the tray 11 sealingly engaging the largest diameter side of the housing 12. In this embodiment, the tray 11 has a disk structure. In order to avoid rusting, the whole three-direction measuring device 1 is mainly made of a material which does not rust, for example, the shell 12 is made of aluminum alloy, and the tray 11 is made of hard plastic.
Referring to fig. 4 and 5, there is shown a river, water surface 4 and river bed 5. The real-time sensing underwater river channel section measuring system further comprises a rope 2 and a conducting wire positioned in the rope 2. The rope 2 is a high-molecular non-telescopic flexible rope, a plurality of three-direction measuring devices 1 are uniformly arranged on the rope 2, and a lead is connected with the three-direction measuring devices 1.

For more accurate measurement, it is preferable to ensure that the pressure receiving directions of the pressure sensors 13 on the left and right sides of each three-direction measuring device 1 are parallel to the water flow direction when arranging.
The function of the polymer non-retractable flexible rope is mainly to adapt to the attachment of the riverbed 5 so as to reflect the depth change of the riverbed 5, and when the riverbed 5 is deeply brushed, the self weight of the shell 12 can enable the rope 2 to fall; the tray 11, however, is not so large in area that the ropes 2 are embedded inside the river bed 5. With the three-directional measuring device 1, the depth change of the river bed 5 can be measured in real time.
When the device is installed, the ropes 2 are laid on the surface of the riverbed 5, and the head and the tail ends of the ropes 2 are fixed on the left and right sides of the riverway by the fixing piles 3. A take-up switch capable of adjusting the extending length of the rope 2 is arranged on the fixing pile 3; the take-up switch can be a rotating shaft, the rope 2 is wound on the rotating shaft, and only the rotating shaft can be fixed with the fixing pile 3. In practice, the rope 2 is released or retracted in part, depending on the situation.
During maintenance, the rope 2 can be directly pulled to drag the three-direction measuring device 1.
