Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river monitoring equipment, in particular to a canal tributary inflow and outflow navigable water flow condition monitoring equipment. BACKGROUND

[0002] With the continuous growth of the global economy, trade activities are becoming more frequent, and canals, as important water transportation channels, bear a large amount of cargo transportation tasks. The increasing amount of cargo transportation makes the requirements for the navigability and safety of the canal higher and higher, and water flow monitoring equipment needs to be used to monitor the water flow conditions of the key areas of the tributary inflow and outflow to ensure the safe and efficient passage of ships.

[0003] The pressure type water level gauge is a commonly used water flow monitoring equipment, and the working principle of the pressure type water level gauge is based on the relationship between the liquid pressure and the depth. It is mainly composed of a pressure sensor component. When the pressure type water level gauge is placed underwater, the water exerts hydrostatic pressure on the pressure sensor. The pressure sensor can sensitively perceive this pressure and convert it into corresponding electrical signals. These electrical signals are amplified and conditioned by the internal signal processing circuit and transmitted out in the form of standard signals. At the receiving end, according to the pre-set values of liquid density and gravitational acceleration, the transmitted signals are analyzed and processed, and the depth of the water level is inversely deduced according to the formula, so as to realize the accurate measurement of the water level height.

[0004] The data collector in the existing water flow monitoring equipment is installed through a plurality of bolts, and when the data collector needs to be removed, a plurality of bolts need to be rotated, which results in a low disassembly rate of the data collector.

[0016] Preferably, two supporting rods are fixedly connected to the bottom side of the clamping plate one and slidingly connected in the inner portion of the floating plate.

[0017] Preferably, one of the clamping plates two is internally mounted with a pressure sensor, one of the clamping plates two is internally slidingly connected with a rubber pad arranged at the left portion of the pressure sensor, a limiting plate one is mounted on the outer periphery of the rubber pad, a limiting groove one is formed in the inner portion of one of the clamping plates two, the limiting plate one is slidingly connected in the inner portion of the limiting groove one, a controller is mounted on the outer periphery of the electric push rod, and the controller is electrically connected with the pressure sensor.

[0018] Preferably, two supporting blocks are fixedly connected to the top rear side of the floating plate, the rotating rod is rotatably connected to the middle portion of the two supporting blocks, and a transmission belt is sleeved on the outer periphery of the rotating rod and the driving end of the motor.

[0022] Working principle: before using the equipment, place the data collector on the top of the floating plate, then start the electric push rod, and the extension end of the electric push rod is extended to drive the two rotating rods to rotate. In the rotating process of the two connecting rods, the two clamping plates two are moved towards the data collector through the two connecting rods. In the moving process of the two clamping plates two, the two connecting blocks are moved, and the two connecting blocks are respectively slid in the two installation grooves, so that the clamping plate two can drive the clamping plate one to move towards the data collector in the moving process. A plurality of clamping plates clamp and fix the data collector to move, so that the data collector can be quickly installed on the top of the floating plate and can ensure the stability of the data collector during operation. When one of the clamping plates two touches the data collector, the data collector pushes the rubber pad to move towards the pressure sensor, so that the rubber pad extrudes the pressure sensor. When the pressure received by the pressure sensor reaches a predetermined value, the pressure sensor can transmit a signal to the controller, and the controller can close the electric push rod after receiving the signal, so as to prevent the plurality of clamping plates from exerting excessive pressure on the data collector.

The protective shell can be fixed on the top of the floating plate to protect the data collector.

[0024] Then the equipment can be placed on the surface of the river flow, the motor is started to drive the winding roller to rotate to unwind the cable, so that the pressure type water level meter is placed in the water. The water flow produces pressure on the pressure sensor, and the pressure sensor in the pressure type water level meter can sensitively perceive the pressure and convert it into a corresponding electric signal. The electric signal is transmitted to the data collector through the cable, and the data collector can analyze and process the electric signal after receiving the electric signal and record it.

[0025] After the monitoring is completed, the motor can be started to drive the motor driving end to drive the winding roller to rotate reversely, so as to wind the cable, and during the winding process of the cable, the motor driving end drives the rotating rod to rotate through the transmission belt, the rotating rod rotates to make the fixed shaft slide in the guide groove, so as to drive the moving block to drive the fixed ring to reciprocate along the rotating rod, so that the fixed ring drives the cable to reciprocate, to prevent the cable from winding during the winding process, and then the device can be taken out from the inside of the river channel.

[0028] 2、 the length of the cable is adjusted by the motor driving winding roller to rotate to wind or unwind the cable, so that the pressure type water level gauge can monitor the river channels with different depths, and the rotating rod rotates to make the moving block drive the cable to move during the winding and unwinding process of the cable, so as to prevent the cable from winding and ensure the normal work of the pressure type water level gauge.
