[0041] A driven pulley 31 and a driving pulley 41 are provided at both ends of the linear track;

[0042] An endless belt / rope 5 is wound between the driven pulley 31 and the driving pulley 41;

[0043] The endless belt / rope 5 is fixedly connected to the slider 43 via a fixing head 53, and can reciprocate around both ends of the linear track when the driven pulley 31 and the driving pulley 41 rotate, thereby driving the slider 43 to reciprocate along the length direction of the linear track;

[0044] The lower end of the slider 43 is provided with a depth measuring weight.

[0045] In some embodiments, the linear track includes one or more titanium alloy rectangular tube segments 11 connected end to end in sequence;

[0046] Each titanium alloy rectangular tube section 11 has a pre-camber of 5%;

[0047] Every two titanium alloy rectangular tube sections 11 are connected by a high-strength hinge 23 .

[0048] In some embodiments, each high-strength hinge 23 is disposed on a side of the corresponding two titanium alloy rectangular pipe sections 11 facing the river channel to be measured, and is fixed to the corresponding two titanium alloy rectangular pipe sections 11 by high-strength rivets 22 .

[0049] In some embodiments, the linear track is provided with grooved tracks 12 extending along the length direction on the side facing away from the river channel to be measured and on both sides;

[0050] The slider 43 is a frame structure with an inner hole, and the inner hole is larger than the cross section of the linear track;

[0051] The inner hole of the slider 43 is provided with a pulley 42 corresponding to each groove track 12 .

[0052] In some embodiments, the active pulley 41 is provided with a rotating handle 44 .

[0053] In practical applications, the endless belt / rope 5 can be a fishing line, and the active pulley 41 can enable the fishing line hand to crank the rod.

[0054] In some embodiments, the sounding weight includes a weight body 55, a weight line 52, and a weight line reel 56;

[0055] The weight drum 56 is set on the bank of the river to be measured;

[0056] One end of the weight line 52 is connected to the weight line drum 56, which passes through the pulley at the lower end of the slider 43. The lower end is provided with a weight body 55, and a plurality of buoys 54 fixed at equal intervals are provided on the rope body.

[0057] In practical application, the steps of implementing river cross-section measurement using the utility model are as follows:

[0059] Step 2: unfold the folded titanium alloy rectangular tube sections 11 connected by the high-strength hinges 23 one by one, with the high-strength hinges 23 facing upwards;

[0060] Step 3: Install a traction fishing line as the endless belt / rope 5 and a depth-finding fishing line as the weight line 52, fasten the pulley 42 of the slider 43 to each groove track 12, and fasten a plurality of equally spaced fixed buoys 54 to the weight line 52 at equal intervals a;

[0061] Step 4: Check the entire device and whether the endless belt / rope 5 dragging the slider 43 is caught or pulled;

[0062] Step 5: Rotate and install the connected complete set of equipment to the embankment support on one side of the river channel to be measured, and flip the complete set of equipment so that the high-strength hinge 23 faces downward. This will change the force of the linear track. The titanium alloy rectangular tube section 11 with a 5% pre-camber will extend in the horizontal direction due to the action of gravity.

[0063] Step 6: Check the entire device again to see if the endless belt / rope 5 drags the slider 43 to see if it is caught or pulled, if the driven pulley 31 and the driving pulley 41 rotate normally, and if the multiple equidistant buoys 54 on the weight line 52 are fastened.

[0064] Step 7: Pull the annular belt / rope 5 to make the length of each pull consistent; and timely retract and release the weight line 52, observe the number n of equidistant fixed buoys 54, the number of water depth values ​​is N, then the water depth h N =a*n, synchronously record water depth h N ;

[0065] Step 8: Repeat the above steps until you reach the opposite shore;

[0066] Step 9: Calculate the cross-section point spacing s: Measure the river width L on the topographic map, then the cross-section point spacing is equal to s = L / (N-1);

[0067] Step 10: Calculate underwater elevation H i :Hi =H0-h i (i:1-N);

[0068] Step 11: Draw the zero stake coordinates on the topographic map; use the graphical method to mark the underwater elevation points one by one at equal intervals s along the section line perpendicular to the river channel.

[0069] like Figure 12 The opposite bank support point shown can be a tree branch, a fence or other supporting objects, and the local bank support point can be a supporting object such as a tripod.
