Description

Technical Field

[0001] This utility model relates to the field of measurement technology, specifically a water level measuring ruler. Background Technology

[0002] A water level gauge is a specialized tool used to directly read the water level of a body of water. It is widely used in fields such as water conservancy, hydrology, environmental protection, agriculture, and industry. Its core function is to obtain the vertical distance of the water surface relative to a certain reference plane, providing basic data for water level monitoring, water volume calculation, flood warning, etc.

[0003] The scales on the currently installed water level gauges are fixed. Although the scales allow for quick manual data reading, they cannot be rotated in strong backlight conditions. Furthermore, the water surface reflects light, causing staff to be constantly exposed to strong light while reading data, which can irritate their pupils and lead to eye pain and tearing. The water surface is positioned at different heights on the scales at different times, meaning staff can only obtain data for the current time period at the gauge itself. Comparing the data requires observations at multiple time points, which can lead to the inability to observe sudden peak data. Utility Model Content

[0004] The purpose of this invention is to provide a water level measuring ruler to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water level measuring gauge includes a fixed column and a rotating bar on one side of the fixed column, and a peak value measuring component located at the left end of the rotating bar. The fixed column has a cylindrical groove at its top, and a first sawtooth block, a second sawtooth block, and a first spring coil are arranged sequentially from top to bottom inside the cylindrical groove. A rotating block is located at the top of the first sawtooth block, and a rectangular groove is located at the top of the rotating bar, with a second spring coil located inside the rectangular groove. A scale is located at the front end of the rotating bar, and cylindrical blocks are located at both the upper and lower ends of the outer ring of the fixed column. Sliding grooves are located on the left and right sides of the rotating bar, and a water level panel is located on the outer ring of the rotating bar.

[0007] The peak value measuring component includes a second sliding opening at the left end of the rotating bar, and a rack at the right end of the second sliding opening corresponding to the inside of the rotating bar. Several rectangular holes are vertically and equally spaced at the front end of the rack corresponding to the front end of the rotating bar. Each rectangular hole contains a Z-shaped block. The bottom front end of the Z-shaped block is provided with a third spring coil, and the top of the rack is provided with an L-shaped plate. A rope is provided at the left end of the L-shaped plate, and a float is provided at the left end of the rope.

[0008] Preferably, the upper and lower ends of the fixing column are welded and fixed to the cylindrical block, and the bottom of the fixing column is provided with a base, and the bottom cylindrical block is welded and fixed to the base.

[0009] In this utility model, the upper and lower ends of the fixing column are welded and fixed to the cylindrical block, and the bottom of the fixing column is provided with a base, and the bottom cylindrical block is welded and fixed to the base.

[0010] Preferably, the bottom of the first spring coil is welded and fixed to the bottom of the inner wall of the cylindrical groove, the first sawtooth block and the second sawtooth block are placed one above the other, and a number of sawtooth-shaped teeth are opened in a ring at equal intervals on the bottom of the first sawtooth block and the top of the second sawtooth block, and the bottom of the first sawtooth block and the top of the second sawtooth block are tightly fitted together.

[0011] In this invention, the bottom of the second sawtooth block is tightly fitted with the first spring coil, the size of the first spring coil is adapted to the cylindrical groove, the outer diameter of the first sawtooth block and the second sawtooth block are adapted to the inner diameter of the cylindrical groove, and the teeth are provided to facilitate the meshing of the bottom of the first sawtooth block and the top of the second sawtooth block.

[0012] Preferably, the first sawtooth block has a through hole in the middle, and the second sawtooth block has a connecting rod in the middle of its top. The bottom of the connecting rod is welded and fixed to the second sawtooth block. The outer ring of the first sawtooth block is welded and fixed to the inner wall of the cylindrical groove near the top. The top of the connecting rod is welded and fixed to the bottom of the rotating block at the corresponding position through the through hole. The upper and lower ends of the second spring ring are welded and fixed to the bottom of the outer end of the connecting rod and the rectangular groove, respectively.

[0013] In this invention, the first sawtooth block is welded and fixed to the cylindrical groove, thus fixing its position. The second sawtooth block is welded and fixed to the connecting rod, and the connecting rod is adapted to the size of the through hole on the first sawtooth block. When the connecting rod is pressed down on the top of the through hole, it causes the second sawtooth block to separate from the first sawtooth block. Simultaneously, the bottom of the second sawtooth block moves downward, pressing down on the first sawtooth block and squeezing the first spring ring. The size of the second spring ring is adapted to the rectangular groove, and the welding fixation ensures that the second spring ring rebounds and is squeezed synchronously when the connecting rod moves up and down. Furthermore, the second spring ring is located inside the rotating bar. When the connecting rod is pressed downwards, the first sawtooth block separates from the second sawtooth block. At the same time, the connecting rod is rotated to adjust the direction, which in turn drives the rotating bar to rotate. Releasing the connecting rod causes the first and second spring coils to spring back. The first spring coil drives the second sawtooth block to move upwards, so that the top of the second sawtooth block fits tightly with the first sawtooth block. The teeth on the second sawtooth block and the teeth on the first sawtooth block are interlaced and fit together. The position of the first sawtooth block is fixed, which in turn fixes the positions of the second sawtooth block, the connecting rod, and the rotating bar, thus achieving rapid adjustment and fixation of the position of the rotating bar on the outer ring of the fixed column.

[0014] Preferably, the inner side of the rotating bar is adapted to the curvature of the outer ring of the fixed column, and a circular groove is opened in the middle of the outer ring of the cylindrical block. An arc-shaped protrusion is provided on the inner side of the rotating bar corresponding to the circular groove. The arc-shaped protrusion is adapted to the shape of the circular groove, and the arc-shaped protrusion is bonded and fixed to the rotating bar. The arc-shaped protrusion is slidably connected to the cylindrical groove, and the front end of the rotating bar is fixedly connected to the scale by screws.

[0015] In this invention, an arc-shaped protrusion and a circular groove are used to limit the vertical movement range of the rotating bar, allowing it to rotate stably around the outer ring of the fixed column. A scale is positioned at the front end of the rotating bar for easy adjustment as the bar changes position. Several E-marks are evenly spaced on the scale, with each E-mark being 25 centimeters high. The entire scale can measure water levels up to 10 meters. The screw-fixed connection allows for quick separation of the old scale and installation of a new one if the scale is damaged. The variable position of the scale on the fixed column allows workers to quickly press the connecting rod to rotate the bar to the appropriate degree when encountering glare from backlighting on the water surface. The height of the water level on the scale is then carefully read and calculated against the height of a reference object to determine the water level.

[0016] Preferably, the bottom front end of the rotating bar is provided with a base block, the base block is fixedly connected to the base by screws, and a plurality of fixing holes are provided at equal intervals in a ring at the bottom top of the base.

[0017] In this invention, the base block and the rotating bar are integrally formed. When the rotating bar is adjusted to the position corresponding to the outer ring of the fixing column, the bottom of the hole in the middle of the rotating bar corresponds to the position of the fixing hole on the base. The screw fixing connection facilitates the quick connection and fixing of the base block and the base, increasing the stability of the bottom of the rotating bar.

[0018] Preferably, a groove is provided at the right end of the rotating bar, and a slider is provided inside the groove corresponding to the water panel. A first sliding opening is provided at the front end of the rotating bar and on both sides of the scale. The slider is welded and fixed to the water panel at the corresponding position. A first sliding opening is provided at the front end of the rotating bar and vertically in the direction of the slider. A threaded groove is provided at the front end of the slider corresponding to the first sliding opening, and a fixing screw is provided in the threaded groove.

[0019] In this invention, the water panel is slidably connected to the rotating bar, and the water panel is welded and fixed to the slider, which facilitates the rapid up-and-down movement and adjustment of the water panel according to the water depth at different times. The first sliding opening facilitates the threaded connection between the fixing screw and the threaded groove on the slider. The fixing screw is screwed into the first sliding opening and into the threaded groove and tightened. The fixing screw is tightly fitted to the front end of the rotating bar, and the rear end of the fixing screw is tightly fitted to the deepest part of the threaded groove, so that the water panel can be fixed when it is moved to the desired position. When the staff comes to observe the data of the water level measuring ruler next time, the positional relationship between the actual water surface position and the water panel allows the staff to intuitively see the change in water level height.

[0020] Preferably, each of the third spring coils has a support plate at its bottom, the support plate is welded and fixed to the front end of the rotating bar, the top and bottom of the third spring coils are welded and fixed to the bottom of the Z-shaped block and the top of the support plate, the top of the rack is welded and fixed to the L-shaped plate, and the rack is engaged with the Z-shaped block. The L-shaped plate is knotted and fixed to the rope, and the float is provided with a rope sleeve, and the rope and the rope sleeve are integrally formed.

[0021] In this invention, a rack with a support plate is slidably connected to the second sliding opening. A torsion spring is provided near the bottom of the Z-shaped block, corresponding to the rotating bar. The bottom of the Z-shaped block is lower at the back and higher at the front, cooperating with the welded and fixed third spring ring and torsion spring. Pressing the front end of the Z-shaped block causes the rear end of the Z-shaped block to separate from the rack. Not pressing the Z-shaped block causes it to quickly return to its original angle. A rope with a float is provided at the left end of the L-shaped plate, so that the water level rises, causing the L-shaped rod and rack to rise synchronously inside the rotating bar. Because the Z-shaped block, the third spring ring, and the torsion spring are in contact with each other... Without manual pressure, the rack cannot descend. This design allows the water level gauge to record peak water level data. By observing the position of the water panel and L-shaped plate on the water level gauge, the water level data can be quickly obtained. Several Z-shaped blocks are set to fix the rack after it rises inside the rotating bar. After the operator finishes reading the data, they can press the Z-shaped blocks corresponding to the top of the third spring ring according to the current water level position to adjust the height of the rack inside the rotating bar to match the water level, making it easier to record the next peak data.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This utility model, by setting a rotating block with a second serrated block and a first spring ring, places the second spring ring inside the rectangular groove corresponding to the rotating block, and cooperates with the arc-shaped protrusion, the circular groove, the threaded groove and the fixing screw to adjust the rotating bar with the scale to a suitable observation angle for the operator and fix it. A peak value measuring component is set inside the rotating bar so that the float moves the L-shaped plate and the rack synchronously as the water level rises. A Z-shaped block and a third spring ring are set to prevent the rack from moving down, thereby realizing the recording of the peak water level data by the water level measuring ruler;

[0024] 2. This utility model achieves rapid adjustment of the water panel according to different water levels by setting a sliding connection between the water panel and the rotating bar. The slider and the fixing screw are threadedly connected to fix the adjusted water panel. A detachable and fixed scale is placed at the front end of the rotating bar and can be replaced according to the wear condition of the scale. Attached Figure Description

[0033] 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.

[0034] Please see Figures 1-5 This embodiment provides a technical solution:

[0035] A water level measuring gauge includes a peak value measuring component 2 comprising a second sliding opening 156 at the left end of a rotating bar 15, and a rack 20 at the right end of the second sliding opening 156 corresponding to the interior of the rotating bar 15. The rack 20 has several vertically spaced rectangular holes at its front end corresponding to the front end of the rotating bar 15. Each rectangular hole contains a Z-shaped block 21. A third spring coil 210 is located at the bottom front end of the Z-shaped block 21, and an L-shaped plate 22 is located at the top of the rack 20. A rope 220 is located at the left end of the L-shaped plate 22. The left end of the rope 220 is provided with a float 221. Each third spring coil 210 has a support plate at its bottom. The support plate is welded and fixed to the front end of the rotating bar 15. The top and bottom of the third spring coil 210 are welded and fixed to the bottom of the Z-shaped block 21 and the top of the support plate, respectively. The top of the rack 20 is welded and fixed to the L-shaped plate 22, and the rack 20 is engaged with the Z-shaped block 21. The L-shaped plate 22 is knotted and fixed to the rope 220. The float 221 is provided with a rope sleeve, and the rope 220 and the rope sleeve are integrally formed.

[0036] In this invention, the rack 20 with a support plate is slidably connected to the second sliding opening 156. A torsion spring is provided in the middle of the Z-shaped block 21 near the bottom, corresponding to the rotating bar 15. The bottom of the Z-shaped block 21 is lower at the back and higher at the front, cooperating with the welded and fixed third spring ring 210 and the torsion spring. Pressing the front end of the Z-shaped block 21 causes the rear end of the Z-shaped block 21 to separate from the rack 20. Removing the pressure on the Z-shaped block 21 allows it to quickly return to its original angle. A rope 220 with a float 221 is provided at the left end of the L-shaped plate 22, enabling the water level to rise, thus driving the L-shaped rod and rack 20 to rise synchronously inside the rotating bar 15. Due to the Z-shaped block 21 and the third spring... With the cooperation of the coil 210 and the torsion spring, the rack 20 cannot descend without manual pressing. This setting allows the water level measuring gauge to record the peak data of the water level height. By observing the position of the water panel 17 and the L-shaped plate 22 on the water level measuring gauge, the water level data can be obtained quickly. Several Z-shaped blocks 21 are set to fix the rack 20 after it rises inside the rotating bar 15. After the staff has read the data, they can press the Z-shaped block 21 and the corresponding position on the top of the third spring coil 210 according to the current water level height to move and adjust the height of the rack 20 inside the rotating bar 15 to match the water level, which is convenient for recording the next peak data.

[0037] The fixed column 1 and a rotating bar 15 on one side of the fixed column 1 are provided, as well as a peak value measuring component 2 provided at the left end of the rotating bar 15. A cylindrical groove 11 is opened at the top of the fixed column 1. A first sawtooth block 12, a second sawtooth block 13 and a first spring coil 110 are arranged in sequence from top to bottom inside the cylindrical groove 11. A rotating block 14 is provided at the top of the first sawtooth block 12. A rectangular groove 150 is opened at the top of the rotating bar 15. A second spring coil 151 is provided inside the rectangular groove 150. A scale 152 is provided at the front end of the rotating bar 15. A cylindrical block 16 is provided at both the top and bottom ends of the outer ring of the fixed column 1. A sliding groove 154 is opened on the left and right sides of the rotating bar 15. A water panel 17 is provided on the outer ring of the rotating bar 15. The top and bottom ends of the fixed column 1 are welded and fixed to the cylindrical block 16 respectively. A base 10 is provided at the bottom of the fixed column 1. The bottom cylindrical block 16 is welded and fixed to the base 10.

[0038] In this utility model, the upper and lower ends of the fixing column 1 are welded and fixed to the cylindrical block 16 respectively, and the bottom of the fixing column 1 is provided with a base 10, and the bottom cylindrical block 16 is welded and fixed to the base 10.

[0039] Secondly, the bottom of the first spring coil 110 is welded and fixed to the bottom of the inner wall of the cylindrical groove 11. The first sawtooth block 12 and the second sawtooth block 13 are placed one above the other. The bottom of the first sawtooth block 12 and the top of the second sawtooth block 13 are circumferentially spaced with a number of sawtooth-shaped teeth, and the bottom of the first sawtooth block 12 and the top of the second sawtooth block 13 are tightly fitted together.

[0040] In this utility model, the bottom of the second sawtooth block 13 is tightly fitted with the first spring coil 110, the size of the first spring coil 110 is adapted to the cylindrical groove 11, the outer diameter of the first sawtooth block 12 and the second sawtooth block 13 is adapted to the inner diameter of the cylindrical groove 11, and the teeth are provided to facilitate the engagement of the bottom of the first sawtooth block 12 and the top of the second sawtooth block 13.

[0041] Specifically, the first sawtooth block 12 has a through hole 120 in the middle, and the second sawtooth block 13 has a connecting rod in the middle of its top. The bottom of the connecting rod is welded and fixed to the second sawtooth block 13. The outer ring of the first sawtooth block 12 is welded and fixed to the inner wall of the cylindrical groove 11 near the top. The top of the connecting rod passes through the through hole 120 and is welded and fixed to the bottom of the rotating block 14. The upper and lower ends of the second spring ring 151 are welded and fixed to the bottom of the outer end of the connecting rod and the rectangular groove 150, respectively.

[0042] In this invention, the first sawtooth block 12 is welded and fixed to the cylindrical groove 11, thus fixing the position of the first sawtooth block 12. The second sawtooth block 13 is welded and fixed to the connecting rod, and the connecting rod is adapted to the size of the through hole 120 on the first sawtooth block 12. It cooperates with the second sawtooth block 13, allowing the connecting rod to press down on the top of the through hole 120, causing the second sawtooth block 13 to separate from the first sawtooth block 12. Simultaneously, the bottom of the second sawtooth block 13 moves down, pressing against the first spring coil 110. The size of the second spring coil 151 is adapted to the rectangular groove 150. Welding and fixing ensures that when the connecting rod moves up and down, it synchronously drives the second spring coil 151 to rebound and press. Furthermore, the second spring coil 151 rotates on the bar... Inside 15, when the connecting rod is pressed downward, the first serrated block 12 and the second serrated block 13 separate. At the same time, the connecting rod is rotated to adjust the direction, which in turn drives the rotating bar 15 to rotate. Releasing the connecting rod causes the first spring coil 110 and the second spring coil 151 to spring back. The first spring coil 110 drives the second serrated block 13 to move upward, so that the top of the second serrated block 13 fits tightly with the first serrated block 12. The teeth on the second serrated block 13 and the teeth on the first serrated block 12 are staggered and fit together. The position of the first serrated block 12 is fixed, which fixes the positions of the second serrated block 13, the connecting rod and the rotating bar 15, realizing the rapid adjustment and fixation of the position of the rotating bar 15 on the outer ring of the fixed column 1.

[0043] Furthermore, the inner side of the rotating bar 15 is adapted to the outer arc of the fixed column 1, and a circular groove 160 is opened in the middle of the outer ring of the cylindrical block 16. An arc-shaped protrusion 153 is provided on the inner side of the rotating bar 15 corresponding to the circular groove 160. The arc-shaped protrusion 153 is adapted to the shape of the circular groove 160, and the arc-shaped protrusion 153 is bonded and fixed to the rotating bar 15. The arc-shaped protrusion 153 is slidably connected to the cylindrical groove 11, and the front end of the rotating bar 15 is fixedly connected to the scale 152 by screws.

[0044] In this invention, an arc-shaped protrusion 153 and a circular groove 160 are used to limit the vertical movement range of the rotating bar 15, allowing the rotating bar 15 to rotate stably on the outer ring of the fixed column 1. The scale 152 is set at the front end of the rotating bar 15 to facilitate changing its position with the rotating bar 15. Several E-shaped marks are evenly spaced on the scale 152, with each E-shaped mark being 25 centimeters high. The scale 152 can measure water levels up to 10 meters. The screw fixing connection allows for quick separation of the old scale 152 and fixation of the new scale 152 when the scale 152 is damaged. The variable position of the scale 152 on the fixed column 1 allows the operator to quickly press the connecting rod to rotate the rotating bar 15 to a suitable degree position when encountering backlighting and glare on the water surface. Then, the operator can carefully read the height of the water surface on the scale 152 and calculate the water level by comparing it with the height of the reference object.

[0045] In addition, a base block 18 is provided at the bottom front end of the rotating bar 15. The base block 18 is fixedly connected to the base 10 by screws. Several fixing holes are opened at equal intervals in a ring at the bottom top of the base 10.

[0046] In this utility model, the base block 18 and the rotating bar 15 are integrally formed. When the rotating bar 15 is adjusted to the position corresponding to the outer ring of the fixing post 1, the bottom of the hole in the middle of the rotating bar 15 corresponds to the position of the fixing hole on the base 10. The screw fixing connection facilitates the quick connection and fixing of the base block 18 and the base 10, increasing the stability of the bottom fixing of the rotating bar 15.

[0047] It is worth noting that a groove 154 is provided at the right end of the rotating bar 15, and a slider 170 is provided inside the groove 154 corresponding to the water panel 17. The front end of the rotating bar 15 and the left and right sides of the scale 152 are provided with first sliding openings 155. The slider 170 is welded and fixed to the water panel 17 at the corresponding positions. The front end of the rotating bar 15 and the slider 170 are provided with first sliding openings 155 in the vertical direction. The front end of the slider 170 and the first sliding opening 155 are provided with threaded grooves 171, and fixing screws 172 are provided in the threaded grooves 171.

[0048] In this invention, the water panel 17 is slidably connected to the rotating bar 15, and the water panel 17 is welded and fixed to the slider 170, which facilitates the rapid up-and-down movement and adjustment of the water panel 17 according to the water depth at different times. The first sliding opening 155 facilitates the threaded connection between the fixing screw 172 and the threaded groove 171 on the slider 170. The fixing screw 172 is screwed into the first sliding opening 155 and the threaded groove 171 and tightened. The fixing screw 172 is tightly fitted to the front end of the rotating bar 15, and the rear end of the fixing screw 172 is tightly fitted to the deepest part of the threaded groove 171, so that the water panel 17 can be fixed when it is moved to the desired position. When the staff comes to observe the data of the water level measuring ruler next time, the positional relationship between the actual water surface position and the water panel 17 allows the staff to intuitively see the change in water level height.

[0049] In this embodiment, the water level measuring gauge is first fixedly connected to the base 10 with the fixed column 1 at the corresponding position on the top of the dam using screws. Then, two cylindrical blocks 16, each with an annular groove 160, are welded and fixed to the upper and lower ends of the outer ring of the fixed column 1. A cylindrical groove 11 with a first spring coil 110 is formed at the top of the fixed column 1. A rotating bar 15 with an arc-shaped protrusion 153 is placed at the corresponding position on the outer ring of the fixed column 1. A rectangular groove 150 with a second spring coil 151 is formed at the top of the rotating bar 15. The front end of the rotating bar 15 is tightly fitted to the scale 152. The cylindrical groove 11 is fixedly connected by screws. The second serrated block 13 and the first serrated block 12 are arranged from bottom to top in the position corresponding to the top of the first spring ring 110. The first serrated block 12 has a through hole 120 in the middle. The top of the second serrated block 13 is provided with a connecting rod corresponding to the position of the through hole 120. The connecting rod and the second serrated block 13 are integrally formed. The top of the connecting rod passes through the through hole 120. The connecting rod and the top of the second spring ring 151 are provided with a rotating block 14. The top of the connecting rod and the top of the second spring ring 151 are respectively welded and fixed to the bottom of the rotating block 14.

[0050] The rotating bar 15 has a second sliding opening 156 and a sliding groove 154 on its left and right sides, respectively. A first sliding opening 155 is opened at the front end of the rotating bar 15, corresponding to the sliding groove 154. Inside the first sliding opening 155 is a slider 170 with a water panel 17. A threaded groove 171 is opened at the front end of the slider 170, corresponding to the first sliding opening 155. A fixing bolt passes through the first sliding opening 155 and is threaded into the threaded groove 171. At this time, the water panel 17 is fixed in position and height on the rotating bar 15. Several support plates with third spring coils 210 are placed at equal intervals inside the second sliding opening 156. The top of each support plate is aligned with the front end of the rotating bar 15. A rectangular hole is made at the corresponding position. A Z-shaped block 21 is welded to the top of each third spring ring 210. A torsion spring is provided on the left side of the Z-shaped block 21 corresponding to the rotating bar 15. A rack 20 is placed inside the second slide 156 corresponding to the rear end of the Z-shaped block 21. The front end of the rack 20 meshes with the Z-shaped block 21. The rack 20 and the L-shaped block at the same horizontal position and passing through the second slide 156 are integrally formed. The left end of the L-shaped block is knotted and fixed to the rope 220 with float 221. A bottom block 18 is provided at the bottom of the front end of the rotating bar 15. The bottom block 18 is threadedly connected to several fixing holes that are equally spaced in a ring on the top surface of the base 10.

[0051] After installation, the staff first presses the rotating block 14 at the top of the cylindrical groove 11 according to the appropriate observation angle, so that the second sawtooth block 13 separates from the first sawtooth block 12. By hand, the rotating bar 15 is rotated to the appropriate position on the outer ring of the fixed column 1 along the direction of the annular groove 160. The rotating block 14 is released, so that the first spring rebounds and moves the second sawtooth block 13 upward until the top of it meshes with the first sawtooth block 12. Then, the bottom block 18 is fixedly connected to the base 10 with screws. At this time, the position of the rotating bar 15 is fixed. The staff unscrews the fixing screw 172 and moves the water panel 17 up or down according to the water level until the corresponding position. The fixing screw 172 is passed through the first sliding hole 155 and fixedly connected to the slider 170. At this time, the fixing screw 172 is tightly fitted to the corresponding front end of the rotating bar 15. Before the staff observes and calculates the water level, the water surface fluctuates to the highest point, causing the float 221 floating on the water surface to move upward. Simultaneously, the L-shaped plate 22 changes its position and height. As the L-shaped plate 22 rises, it causes the front end of the Z-shaped block 21 to press down on the third spring coil 210, causing the rack 20 to move the L-shaped plate 22 up to the peak water level position. The elasticity of the third spring coil 210 cooperates with the Z-shaped block 21, preventing the rack 20 from moving down. After the peak period, the water level decreases, and the length of the rope 220 ensures that the float 221 remains floating on the water surface. The height of the L-shaped plate 22 remains unchanged, allowing staff to record water level data during the observation period and simultaneously record peak water level data. After recording, staff press down on the front end of the Z-shaped block 21 corresponding to the height position of the rack 20 and manually move the L-shaped plate 22 to a position consistent with the water level. To prepare for recording the next peak data, the fixed position and height of the water panel 17 provides a direct comparison before recording water level data again, increasing the convenience for staff to calculate the water level.
