With the push of the cylinder 25, the detection tube 214 can be moved to the water surface, and the motor 24 and the winding roller 23 unwind the cable 210, so that the counterweight block 220, under its own gravity, pulls the first telescopic rod 212 and the second telescopic rod 213 out of the fixed column 211 through the anti-slip block 216 and the detection tube 214, and the counterweight block 220 gradually sinks to the bottom of the water under its own weight, causing the support anchor 35 at the bottom of the counterweight block 220 to be inserted into the mud and sand in the water body.

The inner side of the hinge plate 39 is hinged with a lever 310. If the sand or organisms brought by the water flow hit the detection tube 214, they will first hit the baffle 32, which can make the baffle 32 approach the detection tube 214. Then, the lever 38 at the bottom of the baffle 32 will move the lever 310, so that the position where the lever 310 and the hinge plate 39 are hinged rotates, and the bottom end of the lever 310 is hinged with a limit plate 311, and the limit plate 311 is inserted into the support column. 215 and is located below the slide plate 36. The surface of the slide plate 36 is penetrated and hinged with a reinforcement anchor 312. The top of the tilting rod 310 is close to the detection tube 214, and the bottom of the tilting rod 310 is away from the detection tube 214, so that the tilting rod 310 is pulled out of the limit plate 311. Then the tightened spring 237 will instantly pull the slide plate 36, and the slide plate 36 will slide downward in the support column 215. The slide plate 36 will drive the reinforcement anchor 312 to slide downward together, so that the reinforcement anchor 312 is located in the counterweight block 220, is opened and inserted into the mud and sand of the water body.

[0030] When in use, firstly, the main support arm 1 is installed on the shore by bolts, and then it is determined whether the cable 210 is connected to the liquid level detection probe 217 and the firmware in the operation box 7, and then the motor 24 is started to make the motor 24 drive the winding roller 23 to unwind the cable 210 first, and then the cylinder 25 is started to make the cylinder 25 push the sliding frame 26 to slide on the inner side of the bracket 21, and the slider 27 will slide along the slide groove 22 to ensure that the sliding frame 26 will not deviate when sliding to ensure the stability of sliding, and with the push of the cylinder 25, the detection tube 214 can be moved to the water surface position, and the motor 24 and the winding roller 23 unwind the cable 210, so that the counterweight block 220, under its own gravity, pulls the first telescopic rod 212 and the second telescopic rod 213 out of the fixed column 211 through the anti-drop block 216 and the detection tube 214, and the counterweight block 220 gradually sinks to the bottom of the water under its own weight, which will make the support anchor at the bottom of the counterweight block 220 35 is inserted into the mud and sand in the water body.

Then, the motor 24 can be started again to reverse, so that the winding roller 23 reels the cable 210, and the cable 210 is attached to the surface of the roller 29 to prevent the cable 210 from being excessively worn during rewinding. At the same time, as the cable 210 is rewound, the detection cylinder 214 will be gradually pulled up. Through the slow rise of the detection cylinder 214, the liquid level detection probe 217 can detect the water level of water bodies at different heights. Through the filtering of the filter screen 219 and the pulling of the cable 210 with protective material, it can ensure that the liquid level detection probe 217 can accurately monitor.

[0031] When the water level is detected for a long time, after the counterweight 220 sinks to the bottom, if the water flow is relatively turbulent or there are organisms in the water body that hit the detection tube 214, since the main support arm 1 is installed on the shore, and the water flow on the side close to the shore is slower than the water flow far from the shore, then the water flow close to the baffle 32 is relatively turbulent, carrying more sand and gravel, and there may be more organisms near the middle of the water body. If the sand and gravel or organisms brought by the water flow hit the detection tube 214, they will first hit the baffle 32, which can make the baffle 32 approach the detection tube 214, then the lever 38 at the bottom of the baffle 32 will be pushed. The tilting rod 310 is moved, so that the position where the tilting rod 310 and the hinged plate 39 are hinged rotates, so that the top of the tilting rod 310 is close to the detection tube 214, and the bottom of the tilting rod 310 is away from the detection tube 214, so that the tilting rod 310 is pulled out of the limit plate 311, and then the tightened spring 237 will instantly pull the slide plate 36, and the slide plate 36 will slide downward in the support column 215, and the slide plate 36 will drive the reinforcement anchor 312 to slide downward together, so that the reinforcement anchor 312 is located in the counterweight block 220, is expanded and inserted into the mud and sand of the water body, ensuring that the liquid level detection probe 217 in the detection tube 214 can be stably monitored.
