[0038] A pull ring 13 is sleeved on the middle outer wall of the main equipment box 10, an anchor cable 14 is connected to the pull ring 13, and a fixing ring 15 is arranged below the pull ring 13, and the fixing ring 15 is fixed It is connected to the outer wall of the main equipment box 10, and the fixing ring 15 is provided with four buttons 16 equidistantly, and each button 16 is also provided with a spring one 17.

[0039] A liquid level gauge switch 116 is also provided on the middle inner wall of the housing 101 .

[0040] Specific implementation and principle:

[0041] Under normal circumstances, the device floats on the water surface for monitoring, and the solar panel 11 always generates electricity early and stores the electrical energy in the battery 124. If the battery 124 is fully charged, the compressed air pump 104 is started to pass through the air pipe 105 to the gas compression cylinder 106. Inflatable spare.

[0042] When it rains lightly, the rainwater enters from the water inlet of the upper communication pipe 109 on the top of the casing 101, but will flow out through the outlet of the upper communication pipe 109, and the water level in the upper electrification pipe 113 will not be too high, so it will not start to overturn, and there is a storm. When it rains heavily, the rainwater does not have time to flow out through the outlet of the upper communication pipe 109, so that the water level in the upper electric pipe 113 rises and the upper floating plate 115 is lifted to the top of the upper electric pipe 113. Press the upper button 114, the upper floating plate 115 and the lower floating plate 119 floats on the water, as Figure 8 As shown, at this time, the battery is connected to the self-priming pump 103, and the self-priming pump 103 is driven to reverse (this path is reversed), absorb water from the outside, and the water enters the interior of the housing 101, providing a certain buoyancy to the equipment box 102, and the spring The second 123 lifts the equipment box 102 together, and at the same time the solenoid valve 2 121 opens, the air bag 107 deflates the equipment box 102, and the position of the equipment box 102 rises, so that the center of gravity of the whole device moves up, and finally the device is turned over, and the whole device will sink a little. After the device is turned over, the water level reaches The level gauge switch 116 is at the position, and the self-priming pump 103 is powered off again.

[0043]During a storm, since the rainwater cannot flow out through the outlet of the lower communication pipe 110 in time, the water level in the lower current pipe 117 is always at a high level, and the lower floating plate 119 always floats at the bottom of the lower current pipe 117 (because the device is turned over, the bottom is at a high position ), the lower floating plate 119 is not in contact with the lower button 118; but the rain is small to a certain extent after the rain stops, the water level in the lower electrification tube 117 drops, the lower floating plate 119 descends and contacts and presses the lower button 118, such as Figure 9 As shown, the battery communicates with the self-priming pump 103 again, drives the self-priming pump 103 to rotate forward (this path is positive connection), drains water to the outside, and simultaneously opens the solenoid valve 120, the gas compression cylinder 106 inflates the air bag 107, and the air bag 107 is inflated and stretched , the equipment box 102 is lifted up, so that the center of gravity of the entire device changes and moves upward again, and finally the device is turned back. After turning back, the lower floating plate 119 falls to the bottom of the lower power tube 117 under the action of gravity. The lower floating plate 119 and the lower button 118 Disengage without contact, the circuit is disconnected.

[0044] When the anchor cable 14 is broken, the spring one 17 will push up the pull ring 13, and the four buttons 16 will automatically bounce up, such as Figure 7 As shown in the figure, the self-sinking action circuit is connected, and the self-priming pump 103 in the device is activated to automatically absorb water, and the device is quickly self-sunk to the bottom of the water to prevent floating away and facilitate subsequent salvage.

[0045] Based on the above, the solar cell of the present invention is installed on the top of the device by means of a bracket, which has a larger area and better power generation effect. The monitoring device is fixed in a small area by means of an anchor, which can not only play a more stable monitoring role, It can also prevent the monitoring device from being lost with the waves. In the event of a storm, the device will automatically turn over to protect the solar cell and the camera from wind and rain, and the device will sink as a whole, making it more stable and safer. When broken, the device can quickly sink to the bottom of the water, which is convenient for subsequent salvage and avoids loss.

[0046] It is known from the technical common sense that the present invention can be realized by other embodiments without departing from its spirit or essential characteristics. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
