Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a measuring cup and an automatic measuring system. Background Technology

[0002] When measuring leakage in hydraulic structures such as dams, traditional methods typically employ the volumetric method and the weir method. The volumetric method requires various tools, including a water cup, measuring cylinder, and stopwatch. Observers must carry and operate these tools during the measurement process, which is not only cumbersome but also prone to errors due to improper operation. Furthermore, some measurement environments are poorly lit, further increasing the risk of reading errors.

[0003] The weir method requires setting up a weir at the measurement site and calculating leakage by measuring water level changes. This method not only requires complex equipment but also has high requirements for the measurement environment, making it unsuitable for all hydraulic structures. Furthermore, the weir method requires continuous observation of water level changes during the measurement process, demanding high levels of skill and experience from the observers, and is prone to measurement errors due to human factors.

[0004] With the development of the hydropower industry, higher demands are being placed on the accuracy and efficiency of leakage measurement for hydraulic structures such as dams. The limitations of traditional methods are becoming increasingly apparent, failing to meet the needs of modern hydropower projects. Therefore, developing a leakage measurement tool that simplifies operation, reduces errors, and improves measurement efficiency is of significant practical importance.

[0005] This patent aims to provide an automatic reading leakage measurement cup, which realizes functions such as automatic reading, timing and alarm, and data storage through built-in chip and processor. The concave design of the cup mouth makes it easy to pick up during measurement, and it is easy to operate, carry, reduce errors, and improve the work efficiency of technicians.

[0024] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Among them:

[0026] Figure 2 This is a side view of the present invention.

[0027] Figure 3 This is a flowchart of the leakage measurement process in this utility model. Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Reference Figure 1 This is one embodiment of the present invention. This embodiment provides a measuring cup, including a cup body 1. The measuring time is determined by placing a pipe on the cup body 1 and then adjusting the control component 2. The final measurement data is also displayed on the control component 2.

[0032] Specifically, the cup body 1 includes an irregular groove 1-1, a handle 1-2 fixedly connected to the cup body 1, and a measuring module 2-1 inside the cup body 1. The irregular groove 1-1 and the water pipe form a nested relationship. The inner wall of the irregular groove 1-1 is uniformly provided with irregular patterns, and the depth of the irregular patterns is 0.5 to 1.0 mm. The irregular groove 1-1 and the water pipe are in frictional fit. The pipe is placed by setting the irregular groove 1-1, so that the pipe does not need to be held by manpower or assisted by other tools. This makes the overall measurement process time-saving and labor-saving, and effectively improves the overall work efficiency.

[0033] The measurement module 2-1 is used to automatically measure the amount of liquid inside the cup 1. This is mainly because as the total amount of liquid increases, the weight inside the cup 1 also increases. The pressure sensor 2-1-1 then converts the signal to obtain the measurement result. The entire measurement process is automatic and convenient, and the final measurement result is more accurate than manual observation.

[0034] Preferably, the cup body 1 also includes a handle 1-2 fixedly connected to the cup body 1, and an irregular groove 1-1 communicating with the cup body 1. The width of the irregular groove 1-1 gradually narrows from the cup body 1 outwards, and the irregular groove 1-1 facilitates the discharge of liquid inside the cup body 1.

[0035] Preferably, the irregular groove 1-1 is made of an elastic material, such as silicone, so that when the pipe is placed on the cup body 1, it can be embedded in the irregular groove 1-1 to fix the pipe. At the same time, the elastic material also makes it easy to disassemble the pipe.

[0036] Preferably, the interior of the irregular groove 1-1 adopts an arc-shaped design tangent to the surface of the water pipe, and the inner wall of the irregular groove 1-1 is uniformly provided with irregular patterns, and the depth of the irregular patterns is 0.5 to 1.0 mm.

[0037] This depth range was determined experimentally.

[0038] S1: First, the coefficient of friction (μ) is a dimensionless parameter describing the magnitude of the frictional force between two surfaces, and it is divided into the static coefficient of friction (μs) and the dynamic coefficient of friction (μk):

[0039] Static friction coefficient (μs): The ratio of the maximum frictional force to the normal force before an object begins to slide.

[0040] Dynamic friction coefficient (μk): The ratio of frictional force to normal force during the sliding process of an object.

[0041] Clamping pipes: A high static friction coefficient (μs) is required to prevent pipe slippage.

[0042] Pouring water: A moderate dynamic friction coefficient (μk) is required for easy insertion and removal of the pipe.

[0043] Materials needed: silicone (static friction coefficient μs = 1.60, dynamic friction coefficient μk = 1.00).

[0044] Sample design: Six sets of irregular groove samples were made, with pattern depths of 0.1mm, 0.3mm, 0.5mm, 0.7mm, 1.0mm, and 1.2mm for each set (precision controlled by laser engraving process).

[0045] Pattern type: evenly distributed rhomboid protrusions, with a side length of 2mm and a spacing of 1mm.

[0046] S2: Friction coefficient test

[0047] Testing equipment used: friction coefficient tester (ASTM D1894 standard), constant temperature and humidity environment (25℃, 50%RH).

[0048] Test method:

[0049] Static friction coefficient (μs): The water tube is fixed to the sample surface, and the tension is gradually increased until it slides. The maximum static friction force is recorded.

[0050] Dynamic friction coefficient (μk): The average dynamic friction force was recorded when the water pipe slid at a constant speed of 10 mm / s.

[0051] Positive pressure: uniformly set to 3N (simulating actual usage conditions).

[0052] Repeated testing: Each group of samples was tested 3 times, and the average value was taken.

[0053] S3: Data Recording and Analysis

[0054] Pattern depth (mm) μs (static) μk (dynamic) 0.1 0.6 0.4 0.3 0.9 0.7 0.5 1.2 0.9 0.7 1.4 1.1 1.0 1.6 1.3 1.2 1.8 1.5

[0055] S4: Critical point analysis using line charts

[0056] μs = 0.5 corresponds to a pattern depth of ≈0.25mm, and μs = 1.5 corresponds to a pattern depth of ≈1.05mm.

[0057] μk = 0.5 corresponds to a pattern depth of ≈0.2mm, and μk = 1.5 corresponds to a pattern depth of ≈1.2mm.

[0058] S5: Durability Verification

[0059] Test method: 1000 insertion and removal cycles were performed on samples with pattern depths of 0.5 mm and 1.0 mm.

[0060] S6: Experimental Results

[0061] 0.5 mm sample: μs decreased to 1.0, μk decreased to 0.8 (wear rate ≈ 15%).

[0062] 1.0 mm sample: μs decreased to 1.4, μk decreased to 1.2 (wear rate ≈ 10%).

[0063] Therefore, the preferred range for pattern depth is 0.5–1.0 mm;

[0064] Within this range, μs = 1.2 to 1.6 and μk = 0.9 to 1.3, which meets the target friction coefficient requirement (0.5 to 1.5).

[0065] When the depth is greater than 1.0 mm, μs may exceed 1.5, making it difficult to insert or remove the pipe; when the depth is less than 0.5 mm, μs may be less than 0.5, resulting in insufficient clamping force.

[0066] Optimal depth: 0.7mm (μs=1.4, μk=1.1), balancing clamping force and ease of operation.

[0067] Compensation design: Increasing the pattern distribution density (e.g., reducing the spacing to 0.5mm) can further improve the stability of friction performance.

[0068] Material thickness adjustment: Appropriately increasing the thickness of the elastic material can improve the clamping force while maintaining ease of operation.

[0069] Therefore, elastic materials (such as silicone) with a pattern depth range of 0.5 to 1.0 mm can effectively balance clamping force and ease of operation: ensuring that the pipe will not slip when pouring water and that users can easily insert and remove the pipe.

[0070] Preferably, the control component 2 is electrically connected to the measurement module 2-1 inside the cup body 1.

[0071] Preferably, the control component 2 includes a display screen 2-2 and operation keys 2-3;

[0072] Operation keys 2-3 include left and right keys 2-3-1 and confirmation key 2-3-2.

[0073] Reference Figures 2-3 This is another embodiment of the present invention. This embodiment provides an automatic measurement system, including a processing component 3, which includes an amplifier 3-1, a converter 3-2, and a microprocessor 3-3 electrically connected to the measurement module 2-1.

[0074] Alarm component 4 includes a timer 4-1 electrically connected to the microprocessor 3-3 and a timer 4-2 connected to the timer 4-1.

[0075] Preferably, the measurement module 2-1 includes a pressure sensor 2-1-1. The signal from the pressure sensor 2-1-1 flows through an amplifier 3-1 and is transmitted to a microprocessor 3-3 via a converter 3-2. The pressure sensor 2-1-1 can be a Honeywell SS series sensor, and the converter 3-2 can be an AD7091R-5 model.

[0076] Preferably, timer 4-1 is controlled by operation key 2-3, and timer 4-1 transmits time signals to timer 4-2.

[0077] Once the liquid stabilizes in the cup, gravity causes the pressure sensor 2-1-1 at the bottom of cup 1 to deform, and the resistance of the strain gauge changes accordingly. The strain gauges are connected in a Wheatstone bridge circuit to convert the resistance change into a weak analog voltage signal. This analog voltage signal is amplified by amplifier 3-1 to match subsequent circuits in the signal chain. The analog voltage signal is then converted into a processable digital signal by converter 3-2 and output to microprocessor 3-3 for control. Microprocessor 3-3 calculates the volume of the object based on calibration data and formulas. Microprocessor 3-3 can output the results to display screen 2-2 according to instructions from operation keys 2-3 and the program. It can also control the alarm clock 4-2 and timer 4-1 according to instructions from operation keys 2-3. The memory stores relevant data and programs in conjunction with the microprocessor. The power supply circuit provides the necessary electrical energy.

[0078] Formula for the resistance change of a strain gauge:

[0079]

[0080] in: R is the change in resistance; G is the initial resistance of the strain gauge; ∈ is the sensitivity coefficient of the strain gauge; and ∈ is the strain (the ratio of deformation to the initial length).

[0081] The formula for the output voltage of a Wheatstone bridge is:

[0082]

[0083] Among them, V in ΔR is the input voltage, and ΔR is the change in resistance of the strain gauge.

[0084] Volume calculation formula:

[0085] m=k·V out

[0086] Where m is the mass of the object; k is the calibration coefficient (determined by sensor sensitivity and circuit characteristics); V out It is the output voltage of the bridge circuit;

[0087] From the density formula:

[0088]

[0089] Where: ρ is density (g / cm³) 3 m is mass (grams); V is volume (cm³). 3 )

[0090] For the density of water ρ = 1 g / cm³ 3 Therefore, the formula simplifies to:

[0091] V = m

[0092] That is, the mass (grams) of water is equal to its volume (milliliters).

The measurement data will be automatically displayed on display screen 2-2. There are "Save" and "Delete" prompt keys at the bottom of the page.
