Referring to fig. 5, in the device, an electronic instrument is arranged in a housing 100, an internal data processor 200 receives data sent by an external hydrological tester 400 and then sends the data to a remote end through a communication device 300, the hydrological tester 400 comprises a water level meter 401, a flow meter 402 and a flow rate meter 403 which respectively test water level, water flow rate and water flow rate, the communication device 300 adopts a wireless GPRS transceiver, and a specific model adopts a 4G wireless module of USR-G770. Data processor 200 is implemented with a model number KMPC8555 EVTAPF. As for water level meters, flow meters and flow rate meters, all are prior art. A battery is also provided inside the case 100 to supply electric power to the electronic instrument.

The far end can calculate river flood peak flow according to water level, water flow velocity and water flow, the device sends data to the far end in real time, when the far end detects that a flood peak arrives, a warning is sent, the arrival time of the flood peak can be calculated by determining the position of the device, and therefore the device is an early warning device, the position is advanced, the upstream river data is provided for the far end, and the device can detect the flood peak in advance for the downstream so as to prepare in advance for the downstream.

Just because the environment that this device was settled, it is very far away from with the surveillance center of distal end, and because need the circuit to be connected to testing arrangement, the circuit can not the overlength, otherwise accident easily appears, so this device generally all is located above the surface of water, it is too high when the water level rises, also easily submerged, before this device is submerged, the staff generally is difficult to pack up this device, so it damages to need to make things convenient for the device to be submerged, but when the device itself worked, need the radiating during, guarantee that electronic instrument normally works, so louvre 102 has been set up, and set up water blocking cover 500 outside louvre 102, can shelter from the rainwater, but be useless to the device submerged fact.

This device has set up a closing plate 600 who aims at louvre 102 in casing 100, drives through cylinder 700, and closing plate 600 can laminate casing 100 to shelter from louvre 102, and closing plate 600 is provided with seal groove 601 on sheltering from louvre 102's the terminal surface, sets up sealing washer 602 in the seal groove 601, and sealing washer 602 has surrounded louvre 102, and sealing washer 602 is to protruding seal groove 601, in order to increase the leakproofness.

Generally, the sealing plate 600 is far away from the inner wall of the casing 100, so that the heat dissipation holes 102 dissipate heat inside the casing 100, when the hydrological tester 400 tests that water level data are sent to the data processor 200, at this time, the data processor 200 reads that the water level is higher than a set height, namely, the distance between the device and river water is located at a dangerous position, namely, a command is sent to the air cylinder 700, the air cylinder drives the sealing plate 600 to move, and the sealing plate is attached to the inner wall of the casing 100 to shield the heat dissipation holes 102, so that external water is prevented from entering the casing 100 through the heat dissipation holes 102.

The other parts are waterproof, if the hydrological tester 400 is arranged below the shell 100, the hydrological tester 400 and the data processor 200 need to be connected through a line, the line can penetrate through the shell 100, and waterproof treatment is needed between the line and the shell 100. The waterproof socket and the waterproof plug form a waterproof joint, which is a very existing technology. For example, as shown in fig. 4, the outer end of the waterproof socket 105 is provided with a retaining ring 107, a sealing member is arranged between the retaining ring 107 and the housing 100, the interior of the waterproof socket 105 is fixed by a nut, so that the sealing between the waterproof socket 105 and the housing 100 can be ensured, the waterproof plug 106 is provided with a threaded cover 108, a sealing member is arranged between the threaded cover and the retaining ring 107, and a sealing member is arranged between the threaded cover and the waterproof plug 106, so that the sealing of the connection position can be ensured.

In addition, the casing 100 of the device is also provided with a door 103 for maintenance of internal electronic instruments, one side of the door 103 is hinged, the other side of the door is connected with the casing 100 through a bolt, the end surface of the door 103 facing the casing 100 is also provided with a sealing gasket 104, the sealing gasket 104 surrounds an opening on the casing 100, and the sealing performance is also ensured, and the sealing gasket 104 can be adhered to the door 103 or installed through a groove surrounding a circle.
