[0024] Example

[0025] In existing technologies, most water depth measurement methods involve manually gripping a pole and lowering it underwater to observe the position of the water flow on the pole's surface. This method is only applicable to the riverbanks and shallower areas. In deeper areas, where workers cannot access, related surveying operations cannot be performed.

[0026] Please see Figure 1-5This utility model provides a technical solution: a river hydrological surveying device, including a surveying rod 1 for river hydrological surveying, a roller 2 connected to the surface of the surveying rod 1 by bearings, a side plate 3 fixed to the side of the surveying rod 1, and a base 4 fixed to the top surface of the surveying rod 1. For measuring water depth and facilitating the winding of surveying parts, a surveying component 5 is provided on the surface of the base 4. The surveying component 5 includes a rotating shaft 501, a stranding reel 502, and a nylon rope 503. Two rotating shafts 501 are symmetrically arranged on the side of the base 4, and the rotating shafts 501 are connected to the base 4 by bearings. The stranding reel 502 is fixed between the rotating shafts 501, and the "gap" width of the stranding reel 502 is the same as the diameter of the nylon rope 503. This design allows the nylon rope 503 to be evenly wound around the surface of the stranding reel 502. On the surface of the nylon rope 503, a counterweight is fixed to the end of the nylon rope 503. This device is suitable for rivers with relatively gentle water flow, that is, water areas where the impact force of the water flow cannot drive the nylon rope 503 with the counterweight to deflect. A gripping structure 6 is provided at the end of one shaft 501, and a driving mechanism 7 is provided at the end of the other shaft 501. The driving mechanism 7 is connected to the side plate 3. An indicator component 8 is provided on the surface of the driving mechanism 7. The indicator component 8 is connected to the side plate 3. In order to facilitate the operator to drive the shaft 501 and thus realize the winding operation, a gripping structure 6 is provided. The gripping structure 6 includes a turntable 601 and a bolt 602. The turntable 601 is fixed to the end of one shaft 501, and the bolt 602 is threaded through the inside of the turntable 601.

[0027] To lock the nylon rope 503 during winding or in a certain state, several threaded holes are provided on the outer side wall of the base 4. These threaded holes can be threaded into bolts 602. To facilitate synchronous movement of the indicator parts during unwinding of the nylon rope 503, a drive mechanism 7 is provided. The drive mechanism 7 includes a first bevel gear 701, a second bevel gear 702, and a lead screw 703. The first bevel gear 701 is fixed to the end of another rotating shaft 501. The second bevel gear 702 is meshed with the side of the first bevel gear 701. The lead screw 703 is fixed at the center of the side of the second bevel gear 702, and its end is connected to a bearing on the side wall of the side plate 3. This ensures smooth movement of the nylon rope 503. The rollers 2 are symmetrically distributed about the transverse central axis of the nylon rope 503. There are two sets of rollers 2, with two rollers in each set. In order to display the unwinding length of the nylon rope 503 in real time and facilitate the staff to observe the water depth value, an indicator component 8 is provided. The indicator component 8 includes a slide plate 801, a slide rod 802, and a cross plate 803. The slide plate 801 is threaded onto the surface of the lead screw 703. The slide rod 802 slides through the interior of the slide plate 801. The end of the slide rod 802 is fixedly connected to the side plate 3. The cross plate 803 is attached to the bottom of the slide plate 801. The end of the cross plate 803 is fixedly connected to the side plate 3. The surface of the cross plate 803 is provided with scale lines, which are evenly distributed on the surface of the cross plate 803.

[0028] This device is designed only for manually gripped "measuring rods" and is not designed for existing products of the same type (even when facing similar products, this device has the advantages of convenient numerical reading and simple structure); because this device contains a first bevel gear 701, a second bevel gear 702 and a lead screw 703, it requires relevant personnel to maintain it regularly; the scale lines in this device correspond to the length of the nylon rope 503.

[0029] The working principle or structural principle is as follows: When using this device to conduct water depth mapping in deep water areas of rivers, the operator grips the mapping rod 1 with one hand and uses their elbow to extend the mapping rod 1 into the target mapping area. Next, the bolt 602 is rotated to disengage it from the threaded hole. After that, the rotating shaft 501 can be released from the "locked" state. The nylon rope 503 is unwound under the action of the counterweight. When the nylon rope 503 is unwound, it will drive the stranding disc 502 and the rotating shaft 501 to rotate. Subsequently, the rotating shaft 501 can pass through the first bevel gear 7. 01 and the second bevel gear 702 drive the lead screw 703 to rotate. Because the lead screw 703 is threadedly connected to the slide plate 801, when the lead screw 703 rotates, it will drive the slide plate 801 to move, thereby adjusting its position on the surface of the horizontal plate 803. The operator can know the unwinding length of the nylon rope 503 by the position of the slide plate 801 on the scale line on the surface of the horizontal plate 803. When the counterweight blocks contact the riverbed, they stop moving down, and the rotating shaft 501 and other parts stop running. At this time, the scale on the slide plate 801 is the depth of that section of water.

[0030] In summary, this device has the advantages of a large measurement range and high safety.
