Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, and in particular to a water level monitoring device for flood control assessment. Background Technology

[0002] Flood control assessments require substantial hydrological data, and water level monitoring systems can provide real-time and accurate water level data. Water level monitoring refers to the on-site measurement of water levels in rivers, lakes, and groundwater. Water level is the height of the water surface at a given location above a standard datum. Real-time monitoring of water bodies such as rivers, lakes, and reservoirs using water level monitoring devices can yield crucial data on water level changes, which are essential for the accuracy and scientific validity of flood control assessments.

[0003] Currently, existing water level monitoring devices typically have fixed supports, making it difficult to adjust the distance between the device and the ground. Furthermore, these devices usually determine water level based on the position of an internal float. During testing in turbulent water flow, the strong impact of the current can cause the float to rise, resulting in a position that doesn't match the actual water level. This can lead to false alarms and reduce the accuracy of digital monitoring. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a water level monitoring device for flood control assessment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water level monitoring device for flood control assessment, comprising a base plate, a fixing nail on the bottom surface of the base plate, a fixing tube on the top surface of the base plate, a sliding rod vertically slidably disposed inside the fixing tube, an mounting plate at the upper end of the sliding rod, an outer tube disposed on the mounting plate, an inner tube disposed on the mounting plate inside the outer tube, two first strip-shaped holes symmetrically opened on the outer tube, two second strip-shaped holes symmetrically opened on the inner tube, a plurality of first baffles circumferentially spaced on the inner wall of the outer tube, a plurality of second baffles circumferentially spaced on the outer wall of the inner tube, a floating block vertically slidably disposed inside the inner tube, an mounting ring disposed at the top of the inner tube, a controller and a light assembly disposed at the top of the mounting ring, a button passing through the inner ring of the controller at the bottom, and a push post disposed at the top of the floating block.

[0006] By adopting the above technical solution, a base plate, fixing nails, sliding rods, outer pipe, inner pipe, floating block, and push column are installed. The fixing nails are inserted into the ground, and the sliding rods are used to adjust the mounting plate to a suitable height. Water flows into the space between the outer and inner pipes through the first slot. The impact force of the water flow is dissipated by the first and second baffles, making the water flow between the outer and inner pipes and within the inner pipe smooth. When the water level is high due to the smooth flow, it pushes the floating block and push column upward. When the push column contacts the button, the controller detects the signal, sends information to the central control room, and activates the lights as a warning. This avoids the influence of turbulent water flow on the floating block, ensuring the accuracy of water level monitoring and thus the accuracy of flood control assessment.

[0007] Furthermore, a filter screen is provided on the outer wall of the outer tube at the first strip hole.

[0008] By adopting the above technical solution, a filter screen is installed on the outer wall of the outer pipe at the first strip hole to filter the water flowing into the outer pipe and prevent a large amount of debris from entering the outer pipe and causing blockage.

[0009] Furthermore, an annular filter screen is provided at the top of the outer tube, with the outer ring of the annular filter screen connected to the outer tube and the inner ring connected to the mounting ring.

[0010] By adopting the above technical solution, an annular filter screen is installed at the top of the outer tube to prevent debris from entering the outer tube from the top.

[0011] Furthermore, several of the first baffles and the second baffles are arranged alternately.

[0012] By adopting the above technical solution, the effect of absorbing the impact force of the water flow is better by arranging several first baffles and second baffles alternately.

[0013] Furthermore, the line connecting the two first strip holes is perpendicular to the line connecting the two second strip holes.

[0014] Furthermore, a threaded hole is horizontally opened on the upper part of the fixed tube, and a threaded rod is spirally arranged in the threaded hole. A rotating handle is provided at the end of the threaded rod away from the sliding rod.

[0015] By adopting the above technical solution, a threaded hole, a threaded rod, and a rotating handle are provided. The rotating handle drives the threaded rod to rotate, and when the end of the threaded rod abuts against the sliding rod, the position of the sliding rod is fixed.

[0016] Furthermore, three mounting seats are circumferentially spaced on the outer wall of the fixed tube. A support rod is hinged to the mounting seat. A hinge seat is hinged to the side of the support rod away from the mounting seat. A support plate is provided at the bottom of the hinge seat. Two through holes are opened on the support plate, and ground nails are movably installed in the through holes.

[0017] By adopting the above technical solution, a mounting base, support rod, support plate, and ground nails are set up. After the fixing nails are inserted into the ground, the support rod is swung so that the bottom surface of the support plate contacts the ground. Then, the ground nails are driven into the soil to fix the position of the support plate, thereby enabling the support rod to provide auxiliary support for the fixing pipe.

[0018] Furthermore, a number of connecting rods are circumferentially spaced at the top of the inner tube, with the lower end of the connecting rod connected to the top of the inner tube and the upper end connected to the bottom surface of the mounting ring.

[0019] In summary, this utility model has the following beneficial effects: This application includes a base plate, fixing nails, a sliding rod, an outer pipe, an inner pipe, a floating block, and a push column. The fixing nails are inserted into the ground, and the sliding rod adjusts the mounting plate to a suitable height. Water flows into the space between the outer and inner pipes through the first slot. The impact force of the water flow is dissipated by the first and second baffles, making the water flow between the outer and inner pipes and within the inner pipe smoother. When the water level is high due to the smooth flow, it pushes the floating block and push column upwards. The push column contacts the button, and the controller detects the signal, sends information to the central control room, and activates the lights as a warning. This avoids the influence of turbulent water flow on the floating block, ensuring the accuracy of water level monitoring and thus the accuracy of flood control assessment.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-6As shown in the embodiment of this application, a water level monitoring device for flood control assessment is disclosed, including a base plate 10, a fixing nail 11, a sliding rod 13, an outer tube 30, an inner tube 40, a floating block 43, and a push column 48. The fixing nail 11 is disposed on the bottom surface of the base plate 10, and a fixing tube 12 is disposed on the top surface of the base plate 10. The sliding rod 13 is vertically slidably disposed within the fixing tube 12, and an mounting plate 20 is disposed at the upper end of the sliding rod 13. The fixing nail 11 is inserted into the ground, and the sliding rod 13 is slidably adjusted to a suitable height to adjust the mounting plate 20. The outer tube 30 is disposed on the mounting plate 20, and the inner tube 40 is disposed on the plate body of the mounting plate 20 located inside the outer tube 30, and the inner tube 40 and the outer tube 30 are arranged concentrically. Two first strip-shaped holes 31 are symmetrically opened on the outer tube 30, and two second strip-shaped holes 41 are symmetrically opened on the inner tube 40. The first strip-shaped holes 31 and the second strip-shaped holes 41 enable communication between the outside of the outer tube 30, between the outer tube 30 and the inner tube 40, and within the inner tube 40. Several first baffles 32 are circumferentially spaced on the inner wall of the outer pipe 30, and several second baffles 42 are circumferentially spaced on the outer wall of the inner pipe 40. Water flows into the space between the outer pipe 30 and the inner pipe 40 through the first strip hole 31. The impact force of the water flow is dissipated by the first baffles 32 and the second baffles 42, making the water flow between the outer pipe 30 and the inner pipe 40 and inside the inner pipe 40 more gentle. A floating block 43 is vertically slidably installed inside the inner pipe 40. An installation ring 44 is installed at the top of the inner pipe 40. A controller 45 and a light assembly 46 are installed at the top of the installation ring 44. A button 47 is installed at the bottom of the controller 45, passing through the inner ring of the installation ring 44. A pusher 48 is installed at the top of the floating block 43. When the water level is high in the gentle water flow, it pushes the floating block 43 and the pusher 48 to rise. The pusher 48 contacts the button 47. The controller 45 detects the signal, sends the information to the central control room, and turns on the light assembly 46 as a warning. To avoid the impact of turbulent water flow on floating block 43, the accuracy of water level monitoring is ensured, thereby ensuring the accuracy of flood control assessment.

[0029] Specifically, the line connecting the two first strip holes 31 is perpendicular to the line connecting the two second strip holes 41. Several first baffles 32 and second baffles 42 are arranged alternately, which better absorbs the impact force of the water flow. Several connecting rods 49 are circumferentially spaced at the top of the inner tube 40. The lower end of the connecting rod 49 is connected to the top of the inner tube 40, and the upper end is connected to the bottom surface of the mounting ring 44. There is a gap between the outer wall of the floating block 43 and the inner wall of the inner tube 40.

[0030] During installation, a threaded hole is horizontally opened at the upper part of the fixed tube 12, and a threaded rod 14 is spirally installed in the threaded hole. A rotating handle 141 is provided at the end of the threaded rod 14 away from the sliding rod 13. Rotating the handle 141 drives the threaded rod 14 to rotate. When the end of the threaded rod 14 abuts against the sliding rod 13, the position of the sliding rod 13 is fixed. When the end of the threaded rod 14 separates from the sliding rod 13, the sliding rod 13 can slide inside the fixed tube 12. Three mounting seats 15 are circumferentially spaced on the outer wall of the fixed tube 12. A support rod 16 is hinged to the mounting seat 15. A hinge seat 17 is hinged to the side of the support rod 16 away from the mounting seat 15. A support plate 18 is provided at the bottom of the hinge seat 17. After the fixing nail 11 is inserted into the ground, the support rod 16 is swung so that the bottom surface of the support plate 18 contacts the ground. Two through holes are provided on the support plate 18, and ground nails 19 are movably installed in the through holes. After the bottom surface of the support plate 18 contacts the ground, the ground nails 19 are driven into the soil, thereby fixing the position of the support plate 18, so that the support rod 16 provides auxiliary support for the fixed pipe 12.

[0031] In the specific configuration, to prevent debris in the water flow from entering the outer pipe 30, a filter screen 33 is installed on the outer wall of the outer pipe 30 at the first strip-shaped hole 31 to filter the water flowing into the outer pipe 30 and prevent a large amount of debris from entering the outer pipe 30 and causing blockage. To prevent debris from entering the outer pipe 30 from the top, an annular filter screen 34 is installed at the top of the outer pipe 30. The outer ring of the annular filter screen 34 is connected to the outer pipe 30, and the inner ring is connected to the mounting ring 44.

[0032] The operating principle of a water level monitoring device for flood control assessment in this embodiment is as follows:

[0033] First, insert the fixing nail 11 into the ground. Then, slide the sliding rod 13 to adjust the mounting plate 20 to a suitable height. Next, swing the support rod 16 to bring the bottom surface of the support plate 18 into contact with the ground. Then, drive the ground nail 19 into the soil to provide auxiliary support for the fixing pipe 12 with the support plate 18 and the support rod 16. Then, turn the handle 141 to rotate the threaded rod 14 until the end of the threaded rod 14 abuts against the sliding rod 13, thus fixing the position of the sliding rod 13.

[0034] Water flows into the space between the outer pipe 30 and the inner pipe 40 through the first strip-shaped hole 31. The filter screen 33 filters the water flowing into the outer pipe 30. The first baffle 32 and the second baffle 42 dissipate the impact force of the water flow, making the water flow between the outer pipe 30 and the inner pipe 40 and inside the inner pipe 40 gentle. The water flow between the outer pipe 30 and the inner pipe 40 enters the inner pipe 40 through the second strip-shaped hole 41. When the water level is high, the gentle water flow pushes the floating block 43 and the push column 48 to rise. The push column 48 contacts the button 47. The controller 45 detects the signal, sends the information to the central control room, and turns on the light group 46 as a warning to ensure the accuracy of the flood control assessment.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
