Claims

1. A monitoring device for measuring river water depth and riverbed silt thickness, characterized in that, The device includes a top connecting rod, a middle connecting rod, a bottom connecting rod, and a penetrating head, connected sequentially from top to bottom. The penetrating head has several chamfers on its outer side. The penetrating head is threadedly connected to the bottom connecting rod. A first winch is installed inside the bottom connecting rod, and a second winch is installed inside the top connecting rod. The second winch is connected to a drive mechanism. A rope is wound between the first and second winches. The top, middle, and bottom connecting rods have a through-slot for a sensing plate, which passes through the sliding slot and connects to the rope. A pressure sensor is installed below the sensing plate, and the sensing plate has several water-permeable holes. The drive mechanism drives the second winch to rotate, and the rotational motion of the second winch is converted into linear motion of the rope and the sensing plate connected to the rope along the sliding slot. The pressure sensor detects the presence of water pressure. If water pressure is detected, it indicates that the sensing plate is submerged in water. The drive mechanism then reverses the second winch, while the sensing plate continuously monitors the water pressure. When no water pressure is detected, it means the sensing plate is on the water surface. The drive mechanism then rotates the second winch forward, causing the sensing plate to descend at a constant speed. The pressure sensor on the sensing plate continuously monitors pressure changes. When the pressure suddenly becomes non-linear (i.e., the pressure suddenly increases while the plate continues to descend), it indicates that the plate has entered the silt. At this point, according to distance = speed × time, the river depth is calculated as the drive mechanism's rotational speed multiplied by the time it takes for the sensing plate to descend from the water surface to the point where the pressure suddenly increases. The sensor continues to descend. When the pressure increases infinitely and the second winch can no longer rotate, it indicates that the plate has reached the riverbed. At this point, according to distance = speed × time, the thickness of the silt at the riverbed is calculated as the drive mechanism's rotational speed multiplied by the time it takes for the pressure to increase and for the second winch to stop rotating.

2. The monitoring device for measuring river water depth and riverbed silt thickness according to claim 1, characterized in that, The top connecting rod, middle connecting rod, and bottom connecting rod are connected by snap fasteners.

8. A monitoring method for measuring river water depth and riverbed silt thickness, characterized in that, The method employs the monitoring device for measuring river water depth and riverbed silt thickness as described in any one of claims 1-7, and includes the following steps: Step 1: Drive the penetrator vertically into the bottom of the riverbed using a hammering motion until the solar panel is more than one meter above the water surface. Step 2: The signal control transmitter and receiver starts the drive mechanism. The drive mechanism starts and is ready to drive the second winch to start working. The signal control transmitter and receiver sends a command to the induction plate. The pressure sensor of the induction plate senses whether there is water pressure. If there is water pressure, it means that the induction plate is submerged in water. Then the drive mechanism drives the second winch to reverse. At the same time, the induction plate detects whether there is water pressure in real time. When no water pressure is detected, it means that the induction plate is already on the water surface. Step 3: The signal control transmitting and receiving device sends a command to the drive mechanism, which drives the second winch to rotate forward. The induction plate descends at a constant speed. The pressure sensor of the induction plate monitors the pressure change in real time. When the pressure suddenly changes non-linearly, that is, when the pressure suddenly increases and the pressure plate can continue to descend, it indicates that it has entered the silt. At this time, according to the formula mileage = speed × time, the depth of the river is equal to the rotation speed of the drive mechanism multiplied by the time it takes for the induction plate to go from the water surface to the point where the pressure suddenly increases. Step 4: The sensor continues to descend. When the pressure increases infinitely and the second winch can no longer rotate, it means that the riverbed has been reached. At this time, according to the formula mileage = speed × time, the thickness of the silt at the bottom of the river is equal to the rotation speed of the drive mechanism multiplied by the time from the sudden change in pressure of the sensor plate to the time when the second winch can no longer rotate. Step 5: After receiving the feedback data recorded by the induction plate, the signal control transmitting and receiving device sends a command to the drive mechanism, causing the second winch to reverse until the induction plate emerges from the water surface, thus completing one measurement.
