Specifically, the monitoring terminal carries out video monitoring on the surface of the on-site river, the control unit transmits the video back to the monitoring center through the communication unit, and the monitoring center processes the video to obtain the surface flow rate of the river channel, and the surface flow rate of the river channel is combined with the terrain of the river channel and the like to finally obtain the flow rate of the river channel. However, the flood period is the most needed to monitor the flow velocity of the river channel, and the flood period is mostly accompanied by heavy rainfall, the traditional camera has poor monitoring effect when facing heavy rain, and raindrops have large influence on the surface of the river channel, so that a beacon needs to be set for reference. However, the traditional beacons are all manually put down at the upstream, so that the traditional beacons are dangerous, have high labor input and cannot be monitored at any time. Therefore, the beacon supplementing unit is arranged in the application, so that the beacon can be automatically driven into the river channel at intervals to ensure the monitoring accuracy.
The power supply unit supplies power to each electric device at the terminal, and in consideration of the possibility of power failure in a flood period, the storage battery and the charge-discharge controller are arranged in the device box body and used for outputting electric energy and inputting electric energy, the controller is connected with the mains supply to ensure that the electric quantity in the storage battery is sufficient, and when the mains supply is interrupted, the wave power generation mechanism can still charge the storage battery, so that the speed is low, and the service life of the device can be prolonged.
Wave power generation mechanism realizes through ceramic electricity generation piece, converts the wave energy into kinetic energy and makes ceramic electricity generation piece vibration to the production electric energy, this mechanism can set up a plurality ofly, makes the generated energy more.

The connecting plate is mainly used for connecting the pull rope and the force transmission rope with the elastic sealing belt, but the contact area of the connecting plate and the elastic sealing belt cannot be too much more angular and protruded, so that the sealing belt is prevented from being damaged. Therefore, the connecting plate comprises a circular connecting plate, the edge of the circular connecting plate is provided with an arc-shaped side face, when the connecting plate is pulled by the pull rope, the connecting plate moves in the horizontal direction, and the edge of the connecting plate can not have an edge structure in contact with the elastic sealing belt, so that the service life of the elastic sealing belt is longer.
The beacon supplement unit is positioned in the equipment box body, but the equipment box body is provided with an opening corresponding to the sealing box, so that the beacon cannonball can fly out smoothly. In consideration of the problems of equipment storage and the like, the beacon cannonball needs to be stored in a sealing mode, a sealing door is arranged in the sealing box corresponding to the opening position, and the sealing door needs to be opened when the beacon cannonball is launched. Emission mechanism will set up a plurality ofly, can last the transmission after the interval like this, can be better to the monitoring effect of river course velocity of flow.

When the beacon cannonball is launched, air pressure in the air tank is released, so that air flow enters the pressure cavity and then enters the launching barrel to blow out the beacon cannonball, the direction of the launching barrel is upstream of a river channel and inclines upwards, and the beacon cannonball can fly out a certain distance with the beacon and then release the beacon. The beacon is transmitted only by light weight, so that the flight distance can be very great in windy weather, and the beacon cannot be predicted after flying out, so that the beacon needs to be transmitted after the weight of the beacon shell is increased and the beacon is protected.
Whole equipment can directly take out the seal box and change after the disconnection of pressure pipe and air supply pipe when maintaining the change, and each equipment pipeline gathers into a whole through modes such as welding, bolt fastening in the seal box, and is more convenient when changing, and can guarantee the gas tightness. In addition, in order to monitor the pressure in the gas tank, a pressure gauge connected with the control unit is arranged on the gas tank, so that the pressure can be returned, the use safety of the device is higher, and the control on the flying distance of the beacon cannonball is more accurate. The electromagnetic valve is mainly used for controlling the action of a certain launching mechanism by considering that the launching mechanisms are multiple, and not all beacon shells are shot out at one time.
The environment in which the beacon projectile is stored needs to be dry because of the adhesive problem, but the beacon projectile launches a large opening that needs to be opened, so the sealing door is directly one side size of the sealing box. In order to guarantee sealing, the frame corresponding to the sealing door on the sealing box is provided with a sealing strip and is fixed through magnetic attraction, so that the operation structure is simplified while the sealing door is sealed. The switching to sealing door is realized through electric putter, but at the closure back, can be very firm through the magnet finished piece attach sealing door to on the seal box.
The beacon shell is launched through atmospheric pressure, therefore its afterbody be the disc, agrees with the launching tube internal diameter, and the head be the toper, but the end of head also is the disc, agrees with the launching tube internal diameter, and the shell can obtain sufficient impact force and launch like this, and can guarantee certain accuracy. The head and the tail are fixedly connected by virtue of the connecting column, the floating ball serving as the beacon is also bonded on the connecting column, the bonding structure is disclosed in the figure, other structures can be provided, when the adhesive is selected from paste or syrup, the adhesive can be softened after being soaked in water, and the small ball can break away and float to the water surface under the action of self buoyancy to form the beacon. The below of floater need set up corresponding the bobble and set up the holding tank on layer board and the layer board, this is because the transmission impact force is great in the twinkling of an eye, and this adhesive is the fragility, makes bobble and spliced pole break away from easily, consequently supports through the layer board, and the floater just begins to drop when avoiding the transmission, and can't arrive preset position.
