1. A transboundary-area water-body monitoring and early warning system, comprising:
a monitoring device placed in water body to monitor the water body, wherein the monitoring device comprises a housing body in which a control mechanism, a communication mechanism, a sensor and a power box are arranged;
power ends of the control mechanism, the sensor, and the communication mechanism are electrically connected to an output end of the power box;
control ends of the communication mechanism and the sensor are electrically connected to a control end of the control mechanism;
the control mechanism is configured to receive a signal sent by the sensor, and send the signal from the sensor to a background computer through the communication mechanism;
the housing body comprises a lower housing and an upper housing which are hermetically connected and define an electric installation cavity there between;
the control mechanism, the communication mechanism, the sensor and the power box are installed within the electric installation cavity;
a monitoring probe is installed vertically in a middle of the upper housing and is connected with the sensor, sealing grooves are provided in an upper surface of the lower housing and a lower surface of the upper housing, at positions close to outer edges of the lower housing and the upper housing, respectively;
when the upper housing and the lower housing are assembled, the sealing grooves are arranged facing each other and a sealing water bladder is arranged within the sealing grooves;
the housing body is provided with a water circulation mechanism, which comprises a water inlet end, a water outlet end and an external water connection end;
the water inlet end and the water outlet end of the water circulation mechanism are connected to the sealing water bladder, the external water connection end is in communication with outside of the housing body;
the control end of the control mechanism is connected to a control end of the water circulation mechanism;
the control mechanism is configured to control the water circulation mechanism to fill the sealing water bladder with liquid, the sealing water bladder is expanded so as to come into close contact with groove walls of the sealing grooves;
the water circulation mechanism comprises a water pump unit and three groups of electromagnetic valves; wherein the three groups of electromagnetic valves are respectively arranged at the water inlet end, the water outlet end, and the external water connection end of the water circulation mechanism; and in an initial state, the electromagnetic valves of the water circulation mechanism at the external water connection end and the water inlet end are first switched on, and water in the water body is injected into the sealing water bladder, so that the sealing water bladder is expanded to come into close contact with the groove walls of the sealing grooves;
the water circulation mechanism comprises a water tank, wherein the external water connection end is located on an outer surface of the water tank, and a filter is fixedly connected to the outer surface of the water tank; and
an inner temperature sensor is fixedly connected to an interior of the housing body, an output end of the inner temperature sensor is electrically connected to an input end of the control mechanism, when a temperature value sensed by the inner temperature sensor is greater than a predetermined value, the control mechanism is configured to control and switch on the electromagnetic valves at the external water connection end.
