[0002] Before the construction of water conservancy projects, especially for some cross-water construction projects, in order to determine the construction difficulty and the feasibility of the plan, it is usually necessary to measure the water depth of the target construction point. The measurement process mainly uses sensors to measure. The sensor is put into the water with a rope. When the sensor sinks to the target depth, the sensor detects the water pressure in the target area, and then calculates the water depth based on the water pressure.

[0003] The traditional method of deploying such detection devices is usually to use a winding reel to wind the signal line, and then the user takes a small boat to move it to the target location in the water area, and then the device is deployed manually, which is troublesome during use. Now, with the advancement of technology, unmanned boats are often used to load and transport the signal line to the target area for deployment, which is more convenient and safer.

[0032] The end of the sliding member 143 is fixedly connected to a hook 147. After the storage tube 141 is flipped to a horizontal state, it is movably engaged with its end through the hook 147.

[0034] Working principle: When the device is in use, the remote control hull 21 is placed in the water body and remotely controlled through the remote control and the signal antenna 26. At this time, the electric paddle 23 is controlled to start, so that the remote control hull 21 moves to the target position in the water area, and then the electric telescopic rod 1411 and the servo motor 122 are started. At this time, the output end of the electric telescopic rod 1411 moves out from the inner wall of the remote control hull 21, and the lock of the sliding member 143 is released. At the same time, the servo motor 122 drives the winding reel to unwind the wire 121 through the transmission wheel 123, thereby releasing the enhanced signal line 13. At this time, under the action of the memory spring 1412, the sliding member 143 moves away from the end of the first fixed pulley 144, and at the same time, the hook 147 is moved out from the inside of the end of the storage tube 141. At the same time, the sliding member 143 drives the rack 148 to move synchronously, and the rack 148 and the gear The wheel 1415 is meshed, driving the storage tube 141 to flip downward, and as the rack 148 moves, it drives the top of the traction cable 255 to move closer to the third fixed pulley 149. At this time, the two sets of flip baffles 252 flip downward and open under the action of gravity and the torsion spring 254, and finally the bottom of the storage bin 251 is opened. At the same time, the storage tube 141 rotates to a vertical downward state. At this time, the memory spring 1412 is fully extended, and then the servo motor 122 continues to rotate. By releasing the enhanced signal line 13, the detection probe 11 moves downward from the inside of the storage tube 141 under the action of the light spring 1413 and gravity, and slowly sinks into the water body. Finally, the detection probe 11 sinks to the bottom of the water. At this time, the water pressure at this position is detected by the pressure sensor inside the detection probe 11, and then the water depth at this position is calculated according to the water pressure; After the detection is completed, the servo motor 122 is reversed to make the winding drum 121 reel up the enhanced signal line 13. At this time, the detection probe 11 moves upward to the inside of the storage tube 141 and compresses the light spring 1413. Then the winding drum 121 continues to reel up the enhanced signal line 13. At this time, the enhanced signal line 13 pulls the movable pulley 146 to move, so that the sliding member 143 moves toward one end close to the first fixed pulley 144. At the same time, the sliding member 143 drives the rack 148 to move, and the rack 148 engages with the gear 1415, so that the bottom end of the storage tube 141 flips upward into the storage bin 251. At this time, the traction cable 255 is tightened, and the rack 148 continues to Move, so that the two sets of flip baffles 252 are gradually closed, and at the same time the storage tube 141 is flipped to be close to the top of the storage bin 251. At this time, the hook 147 is inserted into the end of the storage tube 141 to support the end of the storage tube 141. At this time, the sliding member 143 cannot move further, and the electric telescopic rod 1411 is started to insert its output end into the inner wall of the remote-controlled hull 21 to fix the sliding member 143, thereby completing the storage of the device. At this time, the remote-controlled hull 21 is convenient to move to the next point for measurement, so as to avoid the detection probe 11 from being entangled with water plants during the movement. At the same time, after use, it is convenient to carry and effectively avoid damage to the detection probe 11.

A water conservancy detection device according to claim 7, characterized in that: The top of the storage tube (141) is provided with a transverse groove (1416), and the reinforced signal line (13) passes through the transverse groove (1416). The inner top of the storage tube (141) is provided with a light spring (1413), and the bottom end of the light spring (1413) is fixedly connected to a retaining ring (1414), and the reinforced signal line (13) passes through the retaining ring (1414).

10. A method for using a water conservancy detection device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: equipment preparation, placing the remote-controlled boat (21) in the water, and remotely controlling it through the remote controller and the signal antenna (26), at which time the electric propeller (23) is controlled to start, so that the remote-controlled boat (21) moves to the target position in the water area; Step 2: Sample testing, starting the electric telescopic rod (1411) and the servo motor (122), so that the bottom of the storage bin (251) is automatically opened, and the storage tube (141) is automatically turned downward, and the detection probe (11) automatically slides down to the bottom of the water, and performs water pressure testing, and calculates the depth according to the water pressure; Step 3: Recover and transfer. Start the servo motor (122) so that the winding drum (121) reels up the reinforced signal line (13). The detection probe (11) moves upward into the storage tube (141). Then the storage tube (141) flips upward and fits the top of the storage bin (251). At the same time, the bottom of the storage bin (251) is closed. Start the electric propeller (23) to measure the next point, and return after all the point measurements are completed.
