[0018] 2. This mobile measuring instrument for water conservancy surveys sets an L-shaped plug plate to limit the reel frame, so that the reel frame keeps the press switch in a pressed state. As a result, when the counterweight head moves downward under the action of its own gravity, the reel drum can be unrestricted and release the measuring rope, allowing the measuring rope to move down to the bottom of the water body with the counterweight head.

[0019] 3. The mobile measuring instrument for water conservancy survey is equipped with an auxiliary winding component, so that the measuring rope can be wound on the winding drum or casing in an orderly manner when winding or releasing, avoiding the entanglement and knotting of the measuring ropes, which would affect the normal operation of the subsequent ejection component and winding component, thereby ensuring the continuous progress of water depth measurement.

[0032] Example: Refer to Figure 1 、 Figure 2 and Figure 7A mobile measuring instrument for water conservancy survey includes a working box 1 and a measuring rope 2 placed in the working box 1. A roller assembly is provided at the bottom of the working box 1, a winding assembly for winding the measuring rope 2 is provided in the working box 1, a counterweight head 3 is provided at the end of the measuring rope 2 away from the working box 1, an ejection assembly for ejecting the counterweight head 3 is provided in the working box 1, and an auxiliary winding assembly for orderly retracting and releasing the measuring rope 2 is also provided on the winding assembly.

[0033] Specifically, the working box 1 is moved to the ship or the shore of the water body to be measured through the bottom roller assembly, and the winding assembly releases the measuring rope 2. The released length of the measuring rope 2 is the distance between the water depth to be measured and the working box 1. The counterweight head 3 is ejected by setting the ejection assembly, so that the measuring rope 2 flies away from the working box 1 with the counterweight head 3, and the counterweight head 3 automatically falls when it flies to the preset water depth position to be measured. The water depth at this position is calculated based on the straight-line flying distance of the counterweight head 3 and the release distance length of the measuring rope 2 finally pulled by the counterweight head 3. Without setting a longer bracket, water depth measurement at a long distance can be achieved, with a wide measurement range and high social use value and application prospects.

[0036] Furthermore, the counterweight head 3 and the end of the toggle plate 601 are provided with matching inclined surfaces or conical surfaces, and a sliding groove 6011 is provided on the toggle plate 601. A slider 6012 connected to the second elastic telescopic rod 6 is slidably connected in the sliding groove 6011, and a first elastic element 6013 is provided between the slider 6012 and the inner wall of the sliding groove 6011.

[0037] Furthermore, a buffer rubber pad 7 is fixed on the inner wall of the working box 1 and is movably opposed to the winding frame 4. A push switch 701 is fixed inside the buffer rubber pad 7 and is electrically connected to the connecting part 402. The connecting part 402 includes an electromagnet 4021 connected to the output shaft of the driving motor 401 and an iron block 4022 connected to the top of the winding drum 403.

[0038] Furthermore, an L-shaped plug plate 8 is slidably connected to the top of the working box 1, a second elastic element 801 is arranged between the L-shaped plug plate 8 and the top of the working box 1, an extrusion slope is provided at the bottom of the L-shaped plug plate 8, and a slot 9 that cooperates with the L-shaped plug plate 8 is provided at the top of the winding frame 4.

[0039] Furthermore, the auxiliary winding assembly includes a screw 10 rotatably connected to the winding frame 4, a secondary bevel gear 1001 is provided on the screw 10, and a main bevel gear 4031 meshing with the secondary bevel gear 1001 is provided at the bottom of the winding drum 403. A nut seat 1002 is threadedly connected to the screw 10, and a telescopic guide rod 1004 connected to the nut seat 1002 is fixed on the lower side of the winding frame 4. The outer side of the nut seat 1002 is rotatably connected to a sleeve 1003 slidingly connected to the screw 10, and the measuring rope 2 is wound around the sleeve 1003.

[0040] Furthermore, the sleeve 1003 is provided with concave holes 11 evenly distributed around the circumference at one end away from the secondary bevel gear 1001 , and a plug 301 is fixed on the top of the counterweight head 3 to be plugged into the concave holes 11 .

[0041] Furthermore, the auxiliary winding assembly also includes a reciprocating screw rod 12 rotatably connected to the winding frame 4, a sleeve 121 is threadedly connected to the reciprocating screw rod 12, the measuring rope 2 is slidingly connected to the sleeve 121, and a roller meter slidingly connected to the measuring rope 2 is provided on the sleeve 121. Synchronous wheels 13 are provided on the reciprocating screw rod 12 and the winding drum 403, and a synchronous belt is provided between the two synchronous wheels 13.

[0042] Specifically, first, according to the distance between the position to be measured and the working box 1, the winding assembly is controlled to work, and the output shaft of the driving motor 401 drives the winding drum 403 to release the measuring rope 2 through the connecting piece 402. When the winding drum 403 rotates, the main bevel gear 4031 engages with the secondary bevel gear 1001 on the screw 10 for transmission, and the nut seat 1002 moves axially along the screw 10, and the rotation of the screw 10 drives the sleeve 1003 to rotate, so that the measuring rope 2 released by the winding drum 403 is wound around the sleeve 1003 in an orderly manner, avoiding the measuring rope 2 released by the winding drum 403 from being entangled in the working box 1. The number of layers of measuring rope 2 finally wound around the sleeve 1003 is one layer, and the sleeve 1003 is connected to the recessed hole 11 through the plug 301 to drive the counterweight head 3 to rotate synchronously;

[0043] When the take-up drum 403 rotates, the reciprocating screw 12 is driven to rotate by the synchronous belt and the synchronous wheel 13. The sleeve 121 moves up and down along the axial direction of the reciprocating screw 12, so that the measuring rope 2 on the take-up drum 403 is released in an orderly manner up and down. When the released measuring rope 2 is wound by the sleeve 1003, it is slidably connected to the roller meter meter. The roller meter meter is a prior art, so that the roller meter meter counts the length of the measuring rope 2 released by the take-up drum 403.

[0044] After the length of the measuring rope 2 released by the winding drum 403 reaches the length of the distance between the working box 1 and the position of the water depth to be measured, the staff member toggles the toggle plate 601, causing the toggle plate 601 to compress the second elastic telescopic rod 6. When the toggle plate 601 abuts against the counterweight head 3, the toggle plate 601 avoids the counterweight head 3 and slides relative to the slider 6012. After the toggle plate 601 passes over the counterweight head 3, the toggle plate 601 is reset and abuts against the end face of the counterweight head 3, and then the toggle plate 601 is released.

[0045] The toggle plate 601 ejects the counterweight head 3, which slides along the inner wall of the ejection slide 5 and flies out horizontally. When the counterweight head 3 flies to the position of the water depth to be measured, since the remaining measuring rope 2 on the winding drum 403 has not been released, the counterweight head 3 applies a pulling force on the measuring rope 2 to the winding rack 4. The winding rack 4 is subjected to the pulling force and moves to one side of the counterweight head 3. The first elastic telescopic rod 101 is stretched, and the winding rack 4 contacts the buffer rubber pad 7 to unload the force. The power for the counterweight head 3 to continue flying is eliminated, and the winding rack 4 presses the press switch 701 at the same time. The press switch 701 controls the electromagnet 4021 to cut off the power, and the electromagnet 4021 is no longer connected to the iron block 4022, and at the same time the L-shaped plug plate 8 is inserted into the slot 9, which limits the position of the winding frame 4. When the counterweight head 3 moves downward under the action of its own gravity, the winding drum 403 can release the measuring rope 2 without restriction, so that the measuring rope 2 can move down to the bottom of the water body with the counterweight head 3. According to the straight-line flying distance of the counterweight head 3 and the distance that the counterweight head 3 finally pulls the measuring rope 2, the two are at right angles, so the water depth at that position can be calculated. There is no need to set up a longer bracket, and the water depth measurement at a long distance can be achieved. The measurement range is wide, and it has high social use value and application prospects.
