Description

Technical Field

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

[0002] After completion, reservoirs serve multiple functions, including flood control, water storage for irrigation, power generation, and fish farming. Water level is the most direct indicator of water conditions, and its changes are primarily caused by fluctuations in water volume. Monitoring water level changes is crucial for analyzing regional water conditions. Water level monitoring effectively monitors disasters such as floods and levee breaches. It provides data references for delineating warning lines for rivers, lakes, and reservoirs, enabling scientific and effective water condition analysis. Altimetry technology allows for near-real-time monitoring of water level changes, establishing multi-year time series data for water levels, which is extremely important for studying climate change.

[0003] Patent CN 220819151 U discloses a reservoir water level monitoring device, including an installation plate. The bottom of the inner wall of the installation plate is fixedly connected to a uniformly distributed push rod motor. The output end of the push rod motor is fixedly connected to the installation plate and penetrates the bottom of the installation plate. The bottom sides of the installation plate are fixedly connected to uniformly distributed measuring rods. The outer wall of the measuring rod is slidably connected to a U-shaped plate. A rotating shaft is fixedly connected through the middle of the U-shaped plate.

[0004] However, the device still has the following problems: when observing and recording the water level, staff need to observe on-site. If water level data at multiple time points is needed, it is very inconvenient to observe. At the same time, the value is constantly changing when the water surface fluctuates, which increases the difficulty of reading. Utility Model Content

[0005] In order to solve the problems existing in the prior art, a reservoir water level measuring device is provided to solve the problems mentioned in the above technical background.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] This utility model proposes a reservoir water level measuring device, including a bracket, a measuring box fixed on the bracket, a float slidably connected to the measuring box, a recording pen connected to the upper end of the float, recording paper inside the measuring box, a power component on one side of the recording pen, the power component driving the recording pen to record on the recording paper, a switch on the measuring box, the switch being electrically connected to the power component, and a reciprocating sliding pressure rod on the measuring box, the pressure rod cooperating with the switch.

[0008] Preferably, a motor is fixedly installed inside the measuring box, and a toothed gear is detachably connected to the output shaft of the motor, which can drive the pressure rod to slide back and forth.

[0009] Preferably, the measuring box is rotatably connected to a cylindrical cam, and the cylindrical cam is coaxially fixed with a first gear that meshes with a toothed gear. The cylindrical cam has a sliding groove, and the pressure rod is slidably disposed in the sliding groove.

[0010] Preferably, the measuring box is slidably connected to a first insert rod that can slide into the adjacent teeth of the first gear, and the first insert rod is connected to the measuring box via a first spring.

[0011] Preferably, the measuring box has a paper receiving wheel and a paper releasing wheel that rotate inside, and the paper receiving wheel is coaxially fixed with a second gear that meshes with the toothed gear.

[0012] Preferably, the measuring box is slidably connected to a second insert rod that can slide into the adjacent teeth of the second gear. The second insert rod is connected to the measuring box via a second spring, and a coil spring connects the paper feeding wheel to the measuring box.

[0013] Preferably, the power component is an electromagnet, and a magnetic component that cooperates with the electromagnet is fixed on the recording pen. The recording pen is connected to the top of the float via a compression spring, and the magnetic force of the electromagnet is greater than the elastic force of the compression spring.

[0014] Preferably, a water baffle is also fixed on the bracket, and the water baffle has a plurality of water passages, and the water baffle surrounds the outside of the float.

[0015] Preferably, the toothed gear has a positioning groove, and the output shaft of the motor has a positioning block that cooperates with the positioning groove.

[0016] Preferably, the bottom of the bracket is provided with a telescopic rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model is equipped with a pressure rod and a switch. The pressure rod slides back and forth inside the measuring box. Each time the pressure rod slides back and forth, it presses the switch once. The switch energizes the power component, which drives the recording pen to record on the recording paper. This allows for timely and regular capture of water level changes, making the data more continuous and timely, and facilitating the tracking of water level dynamics. At the same time, this method helps to reduce errors caused by the observation angle and can maintain data acquisition in scenarios where manual operation is inconvenient, such as at night or in inclement weather.

[0019] 2. This utility model features a detachable toothed gear mounted on the motor. The toothed gear drives the cylindrical cam to rotate. With the motor's rotational speed remaining constant, the angle of rotation of the cylindrical cam can be changed by altering the number of teeth on the toothed gear. The fewer teeth on the toothed gear, the longer it takes for the cylindrical cam to rotate once, the longer it takes for the pressure rod to reciprocate once, and the longer the interval between pressing the switch. Conversely, the more teeth on the toothed gear, the shorter the pressing interval. The measurement interval can be flexibly adjusted according to factors such as location and environment.

[0020] 3. This utility model is equipped with a water baffle, which can, to a certain extent, offset the impact of water surface fluctuations, making the water level behind the water baffle more stable, reducing the fluctuation of the float on the water surface, and improving the accuracy of measurement.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] refer to Figures 1-6 This embodiment proposes a reservoir water level measuring device, including a support 1, a measuring box 2 fixed on the support 1, a float 3 slidably connected to the measuring box 2, a recording pen 4 connected to the upper end of the float 3, a recording paper 5 inside the measuring box 2, a power component on one side of the recording pen 4, the power component being able to drive the recording pen 4 to record on the recording paper 5, a switch 6 on the measuring box 2, the switch 6 being electrically connected to the power component, and a reciprocating sliding pressure rod 7 on the measuring box 2, the pressure rod 7 cooperating with the switch 6.

[0032] The float 3 floats on the water surface and moves up and down with the water level. The pressure rod 7 slides back and forth inside the measuring box 2. Each time it slides back and forth, it presses the switch 6. When the switch 6 is pressed, it is energized, which energizes the power component and drives the recording pen 4 to move closer to the recording paper 5, thereby making a dot on the recording paper 5. The higher the position of the recording pen 4 on the recording paper 5, the higher the water level at that moment. The lower the position of the dot, the lower the water level at that moment.

[0033] Switch 6 is specifically a push-button spring switch, which typically consists of a push button, a spring, a mounting base, and conductive contacts. The push button is usually made of plastic or metal and has a certain degree of pressing performance and mechanical strength. The spring's function is to allow the button to automatically return to its original position and to ensure the elasticity of the press. The mounting base is used to fix the button and spring, ensuring that their positions do not change. The conductive contacts are the key part connecting the circuit; pressing the button connects or disconnects the circuit through the contacts, thus realizing the switch function.

[0034] The recording paper 5 has scale lines. The vertical scale lines represent the water level height, and the horizontal scale lines represent the recording time.

[0035] A motor 8 is fixedly installed inside the measuring box 2. A toothed gear 9 is detachably connected to the output shaft of the motor 8. The toothed gear 9 can drive the pressure rod 7 to slide back and forth.

[0036] The measuring box 2 is rotatably connected to a cylindrical cam 10. The cylindrical cam 10 is coaxially fixed with a first gear 11 that meshes with the toothed gear 9. A groove is provided on the cylindrical cam 10, and the pressure rod 7 is slidably disposed in the groove.

[0037] After being powered on, the toothed gear 9 rotates continuously under the drive of the motor. Each time the toothed part of the toothed gear 9 meshes with the first gear 11, it will drive the first gear 11 to rotate a certain angle. The first gear 11 will then drive the cylindrical cam 10 to rotate a certain angle, causing the sliding groove on the cylindrical cam 10 to drive the pressure rod 7 to slide a certain distance.

[0038] After the lever 7 slides to the bottom, it will press the switch 6 once, thereby energizing the power component and driving the recording pen 4 to record once.

[0039] The measuring box 2 is slidably connected to a first insert rod 12 that can slide into the adjacent teeth of the first gear 11. The first insert rod 12 is connected to the measuring box 2 via a first spring 13.

[0040] One end of the first insert rod 12 is an inclined surface. When the cylindrical cam 10 rotates and drives the pressure rod 7 to descend, the inclined surface can drive the first insert rod 12 to repeatedly slide into the adjacent teeth of the first gear 11. The first insert rod 12 makes the cylindrical cam 10 rotate only in one direction.

[0041] The cylindrical cam 10 rotates in one direction, which enables the pressure rod 7 to slide back and forth along the groove on the cylindrical cam 10.

[0042] The measuring box 2 contains a paper take-up wheel 14 and a paper release wheel 15 that rotate. The paper take-up wheel 14 is coaxially fixed with a second gear 16 that meshes with the toothed gear 9.

[0043] One end of the recording paper 5 is fixedly connected to the take-up roller 14, and the other end is fixedly connected to the feed roller 15.

[0044] After being powered on, the toothed gear 9 rotates continuously under the drive of the motor. Each time the toothed part of the toothed gear 9 meshes with the second gear 16, it will drive the second gear 16 to rotate a certain angle. The second gear 16 will then drive the take-up roller 14 to rotate a certain angle, thereby causing the take-up roller 14 to wind up a section of recording paper 5, causing the recording paper 5 and the recording pen 4 to move relative to each other, so that the recording pen 4 can record at different positions on the recording paper 5.

[0045] The measuring box 2 is slidably connected to a second insert rod 17 that can slide into the adjacent teeth of the second gear 16. The second insert rod 17 is connected to the measuring box 2 via a second spring 18. A coil spring connects the paper feeding wheel 15 to the measuring box 2.

[0046] When the take-up roller 14 rewinds the recording paper 5, the coil spring continuously applies elastic force to the unwind roller 15, keeping the recording paper 5 between the unwind roller 15 and the take-up roller 14 taut. This helps to keep the recording paper 5 flat during recording and reduces the occurrence of recording errors caused by wrinkles in the recording paper 5.

[0047] When the take-up roller 14 rotates to take up the recording paper 5, one end of the second insert rod 17 is inclined. At this time, the inclined surface can drive the second insert rod 17 to repeatedly slide into the adjacent teeth of the second gear 16. The second insert rod 17 makes the take-up roller 14 rotate only in one direction, preventing the recording error caused by the reverse rotation of the take-up roller 14.

[0048] The power component is an electromagnet 19. A magnetic component that works with the electromagnet 19 is fixed on the recording pen 4. The recording pen 4 is connected to the top of the float 3 through a compression spring 20. The magnetic force of the electromagnet 19 is greater than the elastic force of the compression spring 20.

[0049] The bottom of the float 3 is fixed with a housing, the recording pen 4 slides inside the housing, and the electromagnet 19 is fixed to the outer housing.

[0050] When the lever 7 presses the switch 6 to turn on the power, the electromagnet 19 is energized to generate magnetic force, which attracts the magnetic component fixed on the recording pen 4, causing the recording pen 4 to move closer to the recording paper 5 to make dots for recording.

[0051] A tension spring connects the pressure rod 7 to the measuring box 2. The groove on the cylindrical cam 10 includes an inclined groove and a vertical groove. When the cylindrical cam 10 rotates, it drives the pressure rod 7 to slide downward through the inclined groove. At this time, the tension spring is stretched and stores force. When the pressure rod 7 slides to the position of the vertical groove, under the action of the tension spring, the pressure rod 7 slides upward along the vertical groove.

[0052] By setting up a tension spring and a vertical groove, the pressure rod 7 is quickly pulled to the top after pressing the switch 6 once at the bottom. This prevents the electromagnet 19 from being continuously energized due to the pressure rod 7 pressing the switch 6 for a long time. If the electromagnet is continuously energized, the recording pen 4 will be in constant contact with the recording paper 5. As the float 3 slides up and down, the recording pen 4 may draw a line segment in the vertical direction on the recording paper 5, affecting the reading at that moment.

[0053] After the lever 7 disengages from the switch 6, the electromagnet 19 is de-energized, and the spring 20 drives the recording pen 4 away from the recording paper 5 to reset.

[0054] A water baffle 22 is also fixed on the bracket 1. The water baffle 22 has several water passages and is arranged around the outside of the float 3.

[0055] The baffle plate 22 can, to a certain extent, offset the impact of water surface fluctuations, making the water level behind the baffle plate 22 more stable, reducing the fluctuation of the float 3 on the water surface, and improving the accuracy of the measurement.

[0056] The toothed gear 9 has a positioning groove 21, and the output shaft of the motor 8 has a positioning block that cooperates with the positioning groove 21.

[0057] The output shaft of motor 8 has a threaded hole. After the toothed gear 9 is sleeved on the motor shaft, the upper end face of the toothed gear 9 is higher than the upper end face of the output shaft of motor 8. By screwing a bolt into the threaded hole, the bolt fixes the toothed gear 9 to motor 8.

[0058] Loosening the bolts allows you to replace missing gears with different numbers of teeth.

[0059] The missing tooth gear 9 has a minimum of one tooth. For missing tooth gears with multiple teeth, the teeth are added behind the direction of movement of the first tooth. The center line of the positioning groove 21 coincides with the center line of the first tooth.

[0060] By changing the number of teeth on the missing tooth gear 9, the angle of rotation of the cylindrical cam 10 can be changed each time. The fewer teeth on the missing tooth gear 9, the longer it takes for the cylindrical cam 10 to rotate once, the longer it takes for the pressure rod 7 to reciprocate once, and the longer the interval between pressing the switch 6. Conversely, the more teeth on the missing tooth gear 9, the shorter the pressing interval. The measurement interval can be flexibly adjusted according to factors such as location and environment.

[0061] This adjustable recording interval allows the measurement system to better adapt to the needs of different scenarios. For example, under normal conditions of stable water levels, the recording interval can be slowed down, reducing unnecessary repetitive recording, saving paper and other consumables, and avoiding data redundancy that would burden subsequent data processing and analysis. Conversely, in special circumstances such as torrential rains or floods with drastic water level changes, the recording interval can be sped up to capture water level fluctuations more densely and accurately. This on-demand adjustment feature ensures that key information is not missed while balancing efficiency and cost, making data recording more targeted and practical.

[0062] A telescopic rod is installed at the bottom of the bracket 1. The telescopic rod can adjust the height of the measuring box 2 to adapt to water environments with different water levels.

[0063] A mounting plate is fixed to the bottom of bracket 1.

[0064] A solar panel is fixed to the top of the measuring box 2, and a battery for power supply is fixed inside the measuring box 2. Detailed implementation method:

[0066] S1: Fix the bracket 1 to the area to be measured using the mounting plate at the bottom of the bracket 1, and then adjust the height of the telescopic rod so that the float 3 drives the recording pen 4 to a suitable height on the side of the recording paper 5;

[0067] S2: Power on motor 8 to drive toothed gear 9 to rotate. Toothed gear 9 engages with first gear 11 and second gear 16 on both sides. Toothed gear 9 drives cylindrical cam 10 and take-up roller 14 to rotate intermittently. Cylindrical cam 10 drives pressure rod to slide downward. Take-up roller 14 drives recording paper 5 to rewind, preventing recording pen 4 from recording at the same position on recording paper 5.

[0068] S3: The pressure rod 7 slides along the inclined groove on the cylindrical cam 10. After reaching the lower end and pressing the switch 6, it reaches the vertical groove and is then pulled by the tension spring along the vertical groove to the top of the cylindrical cam 10.

[0069] S4: When switch 6 is pressed, electromagnet 19 is energized, which drives the recording pen 4 to approach the recording paper 5 to complete the dot recording.

[0070] In S3, whether the toothed gear 9 has one tooth or multiple teeth, the angle of rotation of the cylindrical cam 10 is appropriate enough so that after the pressure rod 7 reaches the lower end and starts pressing the switch 6, it will not remain in the inclined groove. When the pressure rod 7 reaches the lower end of the cylindrical cam 10, whether the toothed gear 9 has one tooth or multiple teeth, the pressure rod 7 will complete a complete process from pressing the switch 6 to entering the vertical groove. This prevents the pressure rod 7 from remaining pressed on the switch 6 at the bottom of the inclined groove after the toothed gear 9 disengages from the first gear 11.

[0071] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
