[0026] As Figures 1-3 indicated in a kind of river flood prevention early warning system, including main control terminal and monitoring terminal, the monitoring terminal includes being set in reference plane vertical pole 1, and vertical pole 1 is connected with radar water level gauge 3 by cross bar, the radar water level gauge 3 is located above monitoring liquid level, it can be seen, the main structure of the device still sets up the existing flood prevention equipment, i.e. radar water level gauge 3, itself under the condition of normal power supply, the device can normally carry out the monitoring of water level information and the transmission of information with existing equipment.

[0027] Different from the design of existing structure is, as Figure 4As shown, the vertical rod 1 is a hollow rod, and the inner cavity of the vertical rod 1 is provided with an alarm transmitter 7 and a battery 6 at a position higher than the reference plane, the alarm transmitter 7 and the battery 6 are not in contact and are provided with an electric contact on the adjacent side, that is, the alarm transmitter 7 is not in contact in the normal state, so it will not transmit signals, and the battery 6 will not consume electricity in the case of electrical connection components, so the above two structures can work on standby for a long time, and it should be noted that the position of the alarm transmitter 7 is fixed, and the battery 6 is provided with a traction rope 8 and fixed on the hook 10 by the water-soluble cable tie 9, the water-soluble cable tie 9 can be dissolved and broken after being immersed in water, so the end of the traction rope 8 away from the battery 6 can be separated from the hook 10, and correspondingly, after the water-soluble cable tie 9 is broken, the battery 6 can be electrically connected with the alarm transmitter 7, that is, once the water-soluble cable tie 9 is immersed in water, the battery 6 can be electrically connected with the alarm transmitter 7, and in the case of electrical connection, the alarm transmitter 7 can transmit signals, through which the host terminal can know that the water level exceeds the height of the water-soluble cable tie 9, and thus the real-time water level information can be known, and if multiple sets of alarm transmitters 7, batteries 6 and water-soluble cable ties 9 are provided and the water-soluble cable tie 9 is provided at multiple heights, the water level information at multiple heights can be known, and it can be seen from the above structure that the transmission of the alarm transmitter 7 signal does not depend on external power supply, but depends on the endurance of the battery 6, and since the battery 6 is not electrically connected to other components, the endurance of the battery 6 is very long.

[0028] As shown in Figure 4 The water-soluble cable tie 9 is lower than the alarm transmitter 7 and the battery 6, which ensures that the warning signal transmission is completed before the alarm transmitter 7 and the battery 6 are submerged by the water level.

[0029] As can be seen from the above structure, in order to ensure the normal dissolution of the water-soluble cable tie 9, water needs to enter the inner cavity of the vertical rod 1, and in order to ensure that the water level in the inner cavity of the vertical rod 1 is the same as the water level on site, the reference rod 11 is provided with multiple openings below the water-soluble cable tie 9. That is, once the water overflows the openings, it can enter the inner cavity of the vertical rod 11, and as the water level rises, the water level in the inner cavity of the vertical rod 11 will also rise until it overflows the water-soluble cable tie 9.

[0030] In view of the above characteristics, in order to facilitate the adjustment of the water level height monitored, the height of the hook 10 can be adjusted. By fixing the hook 10 at different heights, the water-soluble cable tie 9 can be immersed in water at a fixed water level height.

[0031] And in order to ensure the normal contact power supply, the battery 6 in the base bar 11 cavity moving direction is vertical. After the water soluble ribbon 9 broken, the battery 6 under the action of gravity, can be pressed on the alarm transmitter 7 and make the contact piece contact to form a loop, and send water level signal.

[0032] Through the above structure, on the basis of the existing flood control equipment, increase the alarm transmitter 7 and the battery 6 used with it, after the water level reaches a certain height, the water soluble ribbon 9 can be dissolved, and the battery 6 contact alarm transmitter 7, and then can send the water level warning signal by the alarm transmitter 7, not dependent on external power supply, and the battery 6 is not powered in normal state, so the use time is very long.

[0033] As a preferred embodiment, in order to facilitate the installation of battery 6, alarm transmitter 7 and related connecting parts, the specific structure of the above vertical rod 1 is that the vertical rod 1 includes the base bar 11 fixed with the reference plane and the extension rod 12 detachably arranged above the base bar 11, which can be separated from the middle position, and other components are convenient to install.

[0034] And as Figure 4 shown, the installation method of the above battery 6 and alarm transmitter 7 is that the alarm transmitter 7 is fixed on the inner side of the base bar 11, the battery 6 is arranged directly above the alarm transmitter 7, and the traction rope 8 is fixed on the hook 10 through the water soluble ribbon 9 after winding upward through the guide rod.

[0035] Finally, in order to ensure the normal use of the equipment in normal weather, the vertical rod 1 is also provided with photovoltaic panel 4 and control box 2. And in order to facilitate the grasp of more weather conditions, the top of the vertical rod 1 is provided with weather instrument 5. And the specific structure of the above weather instrument 5 is that the vertical rod 1 weather instrument 5 includes wind direction monitor, wind power monitor and rainfall monitor.
