Description

Technical Field

[0001] This utility model belongs to the technical field of hydrological measurement equipment, specifically relating to a water level monitoring device for water conservancy surveying. Background Technology

[0002] In water conservancy surveying, accurate acquisition of water level data is fundamental to river regulation, flood evolution analysis, and water conservancy project surveying. Traditional water level measurement relies on fixed devices such as manual water gauges and float-type water level gauges. However, in temporary monitoring scenarios without fixed measurement facilities, such as sudden flood surveys, remote river investigations, or emergency water conservancy assessments, professionals often face unique challenges: when the water surface fluctuates violently due to wind and waves, the reading error of contact measuring rods can reach ±10cm or more; non-contact ultrasonic rangefinders experience a significantly higher failure rate in complex water surface conditions due to echo signal disturbances; and while GNSS dynamic elevation measurement can avoid contact with the water surface, its accuracy in canyon sections is difficult to meet the 1-3cm standard requirements for hydrological surveying due to satellite signal obstruction and multipath effects. Utility Model Content

[0003] The purpose of this invention is to provide a water level monitoring device for water conservancy surveying, which solves the problem of water level monitoring in scenarios without fixed monitoring facilities in the prior art.

[0004] The technical solution adopted by this utility model is: a water level monitoring device for water conservancy surveying, including a float with a long conical structure, a measuring mechanism connected to the top center of the float, a pull rope connected to the top of the float, and an anchor head connected to the end of the pull rope away from the float.

[0005] The feature of this utility model is that,

[0006] The float has a float groove inside along its axis, the top of which extends to the top of the float. The measuring mechanism is slidably connected in the float groove. The float also has a through hole inside along its axis, the top of which communicates with the float groove, and the bottom of which extends to the bottom of the float.

[0007] A vertically positioned sleeve is connected to the top center of the float, and the measuring mechanism is connected to the sleeve via a linear bearing.

[0008] The measuring mechanism includes a measuring float, which is connected to a linear bearing and slidably connected to a float groove. Observation marking lines are opened on the body of the measuring float.

[0009] The measuring float is made of hollow tube, and both ends of the measuring float are closed.

[0010] The measuring float is made of a lightweight, rigid, solid column with a stainless steel skin attached to the outer wall.

[0011] The anchor head includes a central rod, one end of which is connected to a pull rope. Several anchor claws are evenly hinged along the circumference of the central rod. The anchor claws are all located near the bottom of the central rod, and each anchor claw has serrations on the side closest to the central rod.

[0012] Each anchor claw is connected to the central rod via a torsion spring.

[0013] The beneficial effects of this utility model are:

[0014] 1) The long conical structure of the float can effectively reduce wind and wave disturbance and reduce the impact of lateral impact on stability. The measuring float slides with the float through the float groove. The bottom of the measuring float is supported by the buoyancy of the water surface. The current water level is calculated by aiming at the observation mark line with equipment such as a total station or level, realizing temporary water level monitoring under complex hydrological conditions. It is convenient to carry and easy to operate.

[0015] 2) The connection structure of the anchor claws not only ensures the reliability of anchoring during normal use, but also allows for quick release from the snagging state when needed, making it suitable for the repeated deployment and retraction operations required in temporary hydrological measurements.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a water level monitoring device for water conservancy surveying, such as... Figure 1-2 As shown, the device includes a long conical float 1 with a measuring mechanism connected to its top center. A pull rope 2 is connected to the top of the float 1, and an anchor head 3 is connected to the end of the pull rope 2 furthest from the float 1. In use, the anchor head 3 is submerged in the water, and the float 1 is pulled vertically to the surface by the pull rope 2. The long conical structure of the float 1 effectively reduces wind and wave disturbances and minimizes the impact of lateral impacts on the stability of the device. The current water level is calculated by aiming the measuring mechanism with a total station or level.

[0024] Example 1

[0025] The water level monitoring device for water conservancy surveying includes a long conical float 1, a measuring mechanism connected to the top center of the float 1, a pull rope 2 connected to the top of the float 1, and an anchor head 3 connected to the end of the pull rope 2 away from the float 1.

[0026] like Figure 3 As shown, a float 1 has a buoy groove 6 along its axial direction inside, with the top of the buoy groove 6 extending to the top of the float 1. The measuring mechanism is slidably connected within the buoy groove 6. A through hole 5 is also provided inside the float 1 along its axial direction, with the top of the through hole 5 communicating with the buoy groove 6 and the bottom of the through hole 5 extending to the bottom of the float 1. The through hole 5 and the buoy groove 6 are coaxially arranged, facilitating water flow. The measuring mechanism slides through the buoy groove 6 to the float 1, and the bottom of the measuring mechanism is supported by buoyancy. The long conical structure of the float 1 reduces wave reflection, and the water within the through hole 5 is not disturbed by waves, thus ensuring the stability of the measuring mechanism and allowing it to respond only to net changes in water level. The dynamic balance system of the float 1 and the measuring mechanism ensures a stable water level mark below the dynamic water surface. The water level mark value is then measured by onshore equipment, enabling temporary water level monitoring under complex hydrological conditions. This method is portable and easy to operate.

[0050] The float 1 has a float groove 6 inside along its axial direction. The top of the float groove 6 extends through to the top of the float 1. The measuring mechanism is slidably connected in the float groove 6. The float 1 also has a through hole 5 inside along its axial direction.

[0053] The measuring float 4 is set as a lightweight, rigid, solid column, and the outer wall of the column is covered with a stainless steel skin.

[0054] like Figure 5 As shown, the anchor head 3 includes a central rod 10, one end of which is connected to the pull rope 2. Several anchor claws 11 are evenly hinged along the circumference of the central rod 10, with each anchor claw 11 positioned near the bottom of the central rod 10. Each anchor claw 11 has serrations on its side closest to the central rod 10.

[0055] Example 7

[0056] The water level monitoring device for water conservancy surveying includes a long conical float 1, a measuring mechanism connected to the top center of the float 1, a pull rope 2 connected to the top of the float 1, and an anchor head 3 connected to the end of the pull rope 2 away from the float 1.

[0057] The float 1 has a float groove 6 inside along its axial direction. The top of the float groove 6 extends through to the top of the float 1. The measuring mechanism is slidably connected in the float groove 6. The float 1 also has a through hole 5 inside along its axial direction. The top of the through hole 5 communicates with the float groove 6, and the bottom of the through hole 5 extends through to the bottom of the float 1.

[0058] A vertically arranged sleeve 7 is connected to the top center of the float 1, and the measuring mechanism is connected to the sleeve 7 through a linear bearing 8.

[0059] The measuring mechanism includes a measuring float 4, which is connected to a linear bearing 8 and slidably connected to a float groove 6. Observation marking lines 9 are provided on the body of the measuring float 4.

[0060] The measuring float 4 is set as a lightweight, rigid, solid column, and the outer wall of the column is covered with a stainless steel skin.

[0061] like Figure 5 As shown, the anchor head 3 includes a central rod 10, one end of which is connected to the pull rope 2. Several anchor claws 11 are evenly hinged along the circumference of the central rod 10. The anchor claws 11 are all located near the bottom of the central rod 10, and each anchor claw 11 has serrations on the side near the central rod 10.

[0062] Each anchor claw 11 is connected to the central rod 10 via a torsion spring. The anchor claw 11 grips the bottom of the riverbed. When snagging occurs, pulling the rope 2 upwards forces the anchor claw 11 to overcome the torque of the torsion spring and rotate it to a position nearly parallel to the central rod 10. At this point, the anchor claw 11 can disengage from the obstacle, thus effectively preventing the anchor head 3 from getting stuck on the bottom of the riverbed. This ensures the reliability of anchoring during normal use and allows for quick release from snagging when needed, making it suitable for repeated deployment and retrieval operations in temporary hydrological surveys.

[0063] The working principle of this utility model water level monitoring device for water conservancy surveying is as follows:

[0064] Anchor head 3 is submerged to the bottom of the water, and anchor claw 11 is stably gripped at the bottom of the riverbed. The pull rope 2 is tightened, and the saw teeth can increase the friction between the anchor claw and the riverbed. The pull rope 2 pulls the float 1 so that it is vertically suspended on the water surface. The long conical structure of the float 1 can effectively reduce the disturbance of wind and waves and reduce the impact of lateral impact on the stability of the device. The current water level can be calculated by aiming at the observation mark line 9 with a total station or level.

[0065] This utility model relates to a water level monitoring device for water conservancy surveying. It uses a dynamic balancing system of floats and measuring buoys to ensure a stable water level mark under dynamic water surface. The water level mark value is then measured by onshore equipment, thereby realizing temporary water level monitoring under complex hydrological conditions. It is portable and easy to operate.
