Description

Technical Field

[0001] This utility model relates to a detection system, and more particularly to an intelligent detection system for standard metal measuring instruments. Background Technology

[0002] In the testing system for measuring standard metal measuring instruments, existing technologies are widely used in metrological calibration, industrial quality control, and laboratory testing, primarily to ensure the accuracy of the instrument's capacity. This system typically includes a testing container, a water pump for rapid filling, a peristaltic pump for fine adjustment, a measuring tube mounted on the testing container, and the metal measuring instrument to be tested. The process is as follows: First, the water pump fills the testing container with water until it approaches the predetermined capacity; then, the peristaltic pump takes over the filling process, slowly and precisely filling the remaining capacity to ensure the water level reaches the standard value. Operators must monitor the water level changes through the measuring tube and manually observe the water level as it approaches the target value to confirm it is in place. The entire process involves multiple interruptions and checks to ensure measurement accuracy. While ensuring accuracy, this system also relies on continuous human intervention.

[0003] However, existing technologies have significant drawbacks. First, during the critical stage when water reaches the metering tube, operators need to periodically check the water level manually, which not only leads to frequent interruptions in the testing process but also reduces overall work efficiency. Second, because the water in the testing container is transported to the container under test by gravity, the metering tube is usually located at a high position, forcing operators to climb to observe it. This not only increases the physical burden but may also introduce safety risks and human error, further affecting the reliability and convenience of the testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent detection system for standard metal measuring instruments that eliminates the need for manual observation, improves efficiency, and reduces risks.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a standard metal measuring instrument intelligent detection system, comprising a detection container, a water pump for rapid water injection and a peristaltic pump for slow water injection, and a metering tube disposed on the detection container, further comprising a control box and a water level monitoring mechanism, wherein the control box has a built-in flow meter, the control box controls the water pump to inject water into the detection container before the detection container reaches a set water level, the control box controls the peristaltic pump to inject water into the detection container after the detection container reaches the set water level and before the detection water level, the control box controls the peristaltic pump to inject water into the detection container, the water level monitoring mechanism is disposed on the metering tube and shuts off the peristaltic pump through the control box after the metering tube reaches a predetermined position.

[0006] The beneficial effects of this utility model are as follows: The system intelligently switches between the water pump and the peristaltic pump according to the water level stage through the control box, and automatically shuts off the peristaltic pump in conjunction with the water level monitoring mechanism. This completely solves the problems of detection interruption and low efficiency caused by manual intermittent observation of the water level in the prior art. At the same time, it avoids the physical burden, safety risks and human error caused by operators climbing to observe, significantly improving the reliability and convenience of detection. As a preferred method, the water pump can be a centrifugal water pump, which generates centrifugal force by driving the impeller to rotate at high speed through a motor to achieve rapid water delivery. The flow meter in the control box collects the water injection data in real time. When the water volume approaches the set water level, the control box automatically cuts off the power to the water pump and starts the peristaltic pump. The peristaltic pump slowly delivers water by squeezing the elastic hose to ensure accurate water injection when approaching the detection water level. As another preferred method, the water level monitoring mechanism can use an ultrasonic liquid level sensor. This sensor is installed on the top of the metering tube. It calculates the water level height by emitting ultrasonic waves and receiving the reflected waves from the water surface. When the water level reaches the predetermined position, the sensor sends an electrical signal to the control box, and the control box immediately stops the peristaltic pump. The entire process requires no manual intervention and fully automates the water injection detection.

[0007] Furthermore, the water level monitoring mechanism includes a mounting frame, a detection tube fitted over the metering tube and marked with a line, and an adjustment device that can move relative to the mounting frame. The adjustment device is equipped with a camera, which shuts off the peristaltic pump via a control box when it detects that the water level has reached the marked line.

[0008] In this technical solution, the mounting frame provides stable support for the detection tube and adjustment device. The transparent detection tube and marking line provide a clear water level identification benchmark for the camera equipment. The movable adjustment device allows the camera equipment to adapt to the metering tube positions of different sized detection containers, avoiding frequent replacement of monitoring components and reducing operating costs. As a preferred option, the detection tube is made of highly transparent polycarbonate material, which is impact-resistant and not easily deformed. The marking line is printed on the outside of the detection tube with black high-temperature resistant ink, forming a clear visual contrast with the water, facilitating rapid identification by the camera equipment. As another preferred option, the adjustment device is equipped with horizontal and vertical guide rail structures. The horizontal guide rail is fixed to the crossbeam of the mounting frame, and the vertical guide rail is slidably connected to the slider of the horizontal guide rail. The camera equipment is mounted on the slider of the vertical guide rail. By pushing the vertical guide rail along the horizontal guide rail and the slider along the vertical guide rail, the camera equipment can be precisely aligned with the detection tubes of different sized detection containers.

[0009] Furthermore, the adjustment device can drive the camera equipment to achieve three-axis movement.

[0010] The adjustment device enables three-axis movement, allowing the camera to be precisely moved to the corresponding detection tube position in the vertical and horizontal directions. Focusing is then achieved through forward and backward movement, ensuring clear water level images captured by the camera and preventing errors in water level identification due to blurry focus or positional misalignment, thus improving monitoring accuracy. As a preferred method, the three-axis movement of the adjustment device employs a screw-slide structure. The vertical sliding table is vertically fixed to the mounting frame, and the horizontal sliding table is bolted to the sliders of the vertical and horizontal sliding tables. The forward and backward sliding table is bolted to the sliders of the horizontal and backward sliding tables. The camera is mounted on the sliders of the forward and backward sliding tables. Rotating the handwheels of each slide drives the screw to rotate, moving the sliders to achieve three-axis adjustment. Alternatively, the three-axis movement mechanism of the adjustment device is equipped with a miniature stepper motor. The motor is connected to the control box via wires, allowing the operator to control the motor rotation via buttons on the control box, driving the camera to achieve automatic three-axis movement without manual adjustment, further enhancing operational convenience.

[0011] Furthermore, the adjustment device includes three sets of identical vertical moving components, horizontal moving components, and forward and backward moving components. The vertical moving components are mounted on the mounting frame, the horizontal moving components are mounted on the vertical moving components, the forward and backward moving components are mounted on the vertical moving components, and the camera device is mounted on the forward and backward moving components.

[0012] This solution employs three sets of identical movable components to form the adjustment device, simplifying the production and replacement process of parts and reducing equipment maintenance costs. Simultaneously, the sequential connection of the three sets of components enables precise three-axis adjustment, allowing the camera equipment to accurately align with and stably fix the detection tube. The meshing force between the components prevents equipment displacement during water injection. As a preferred approach, each movable component uses a gear and rack mechanism. The rack is fixed to the fixed end of the component, and the gear is mounted on the movable end and meshes with the rack. The movable end connects to the fixed end of the next movable component. The meshing transmission of the gear and rack not only provides precise adjustment but also stabilizes the position of the movable end. Alternatively, each movable component's gear shaft is equipped with a locking nut. After the camera equipment is adjusted to the appropriate position, tightening the locking nut locks the gear, further enhancing the fixing effect between components and preventing positional displacement due to gear wear after prolonged use.

[0013] Furthermore, the up-and-down moving component includes a rack seat and a gear seat that cooperates with the rack seat. The gear seat is used to connect other moving components or camera equipment. The rack seat is provided with a limiting platform that cooperates with the gear seat to prevent the gear seat from falling off. A rack is provided at the center of the limiting platform. The gear seat is provided with a rotating wheel that cooperates with the rack. One end of the rotating wheel is exposed outside the gear seat.

[0014] The vertical moving assembly achieves stable movement through the engagement of the rack and pinion seat and the gear seat. The limiting platform effectively prevents the gear seat from detaching, enhancing structural safety. The exposed rotating wheel facilitates manual adjustment by the operator, and the gear seat can flexibly connect different components, enabling orderly combinations of the moving components. As a preferred method, the rack and pinion seat is made using an aluminum alloy extrusion molding process. The limiting platforms are symmetrically arranged on both sides along the length of the rack and pinion seat. The rack is fixed to the central groove between the two limiting platforms by bolts. The inner side of the gear seat has a sliding groove corresponding to the limiting platform, which slides in conjunction with the limiting platform to ensure smooth movement of the gear seat along the rack and pinion seat. As another preferred method, the rotating wheel is made of engineering plastic with anti-slip textures on its surface, preventing slippage when the operator rotates it. The rotating wheel is coaxially fixed with the transmission gear inside the gear seat. Rotating the rotating wheel drives the transmission gear to mesh with the rack, driving the gear seat to move up and down along the rack and pinion seat. The adjustment process is effortless and precise.

[0015] Furthermore, the rack seat and gear seat are respectively provided with scale lines for reading.

[0016] The corresponding scale lines on the rack and pinion seats allow operators to accurately determine the movement distance of the gear seat relative to the rack and pinion seats, avoiding blind adjustments and ensuring that the camera equipment can accurately align with the detection tube or achieve focus, thereby guaranteeing the accuracy of water level monitoring. As a preferred method, the scale lines are laser-engraved in white, creating a clear contrast with the black surfaces of the rack and pinion seats for easy reading. Alternatively, the scale lines on the rack and pinion seats are spaced 1mm apart, and a reference scale line is set on the gear seat. Operators can directly obtain the movement distance of the gear seat by observing the corresponding scale value of the reference scale line on the rack and pinion seats, eliminating the need for additional calculations and improving adjustment efficiency.

[0017] Furthermore, the control box is equipped with a display screen that is connected to the camera equipment.

[0018] The display screen on the control box, connected to the camera equipment, can show the water level in the detection tube in real time. Operators can observe water level changes from the ground without climbing, completely eliminating the safety risks and physical exertion associated with climbing. It also allows for the timely detection of abnormalities such as blurry camera focus or obstructed marker lines, facilitating rapid handling. As a preferred feature, the display screen has a magnification function, allowing operators to zoom in 2-5 times using buttons on the control box for a clearer view of whether the water level has accurately reached the marker line, avoiding misjudgments caused by a small image.

[0019] Furthermore, the water level monitoring mechanism also includes a scale extending upward from the measuring tube. The detection tube is detachably fixed to the scale and can slide along the scale. The detection tube is provided with marking lines corresponding to the scale for its reading.

[0020] The scale extending upwards from the measuring tube allows for calculation of the water volume using the cylinder volume formula, based on the tube's diameter. This facilitates adjusting the water volume in the measuring tube to match the capacity of the container being tested, ensuring a consistent testing standard. The detachable and sliding design of the measuring tube adapts to containers of different capacities, enhancing the equipment's versatility. As one preferred method, the scale is made of 304 stainless steel with a brushed finish. The graduations are etched and filled with red ink, achieving a 1mm accuracy. Operators can quickly calculate the water volume by comparing the graduations with the inner diameter of the measuring tube. Alternatively, the measuring tube is fixed to the scale's slider using butterfly bolts. The slider and scale slide together; loosening the butterfly bolts moves the slider along the scale, adjusting the measuring tube's position, and tightening the bolts secures it. This simple and quick operation requires no special tools. Attached Figure Description

[0024] Figure 4 This is a schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0025] This utility model embodiment provides an intelligent detection system for standard metal measuring instruments, such as... Figures 1-4 As shown: The system includes a detection container 1 for holding the water volume to be tested. The detection container 1 can be a cylindrical structure made of stainless steel, with a metering tube 2 for measuring the water level on one side of its top. The metering tube 2 is a tubular structure made of transparent glass or polycarbonate and is connected to the interior of the detection container 1 to synchronously reflect the water level inside the detection container 1. The system is also equipped with a water pump (not shown in the figure) for rapid water injection and a peristaltic pump (not shown in the figure) for slow water injection. The water pump (not shown in the figure) can be a conventional centrifugal water pump to achieve rapid water replenishment at a large flow rate. The peristaltic pump (not shown in the figure) adopts a conventional peristaltic pump structure with a flexible hose, which achieves precise water injection at a small flow rate by squeezing the hose. The outlets of both the water pump (not shown in the figure) and the peristaltic pump (not shown in the figure) are connected to the inlet of the detection container 1 through pipes.

[0026] It also includes a control box 5 for controlling the overall water injection process and a water level monitoring mechanism 6 for monitoring the water level. The control box 5 is a box structure with built-in circuit modules. Inside it, a flow meter (not shown in the figure) for monitoring the water injection volume is fixedly installed. The flow meter (not shown in the figure) is connected in series with the water pump (not shown in the figure) and the peristaltic pump (not shown in the figure) and the detection container 1. It can collect water injection flow data in real time and transmit it to the controller in the control box 5. A display screen 52 connected to the subsequent camera equipment is also fixedly installed on the outer panel of the control box 5. The display screen 52 is a conventional high-definition IPS screen, which can display the water level image captured by the camera equipment in real time, making it convenient for operators to observe from the ground.

[0027] The water level monitoring mechanism 6 is located above the metering tube 2 and includes a mounting bracket 61 fixed on the side support of the detection container 1, a detection tube (not shown in the figure) sleeved on the outside of the metering tube 2, an adjustment device 63 for adjusting the position of the camera equipment, and a scale (not shown in the figure) that cooperates with the detection tube (not shown in the figure). The detection tube (not shown in the figure) is made of transparent material and is coaxially set with the measuring tube 2. Its outer wall is printed with marking lines (not shown in the figure) to indicate the target water level. The marking lines (not shown in the figure) are printed with high-temperature resistant black ink, which forms a clear visual contrast with the water body. The scale (not shown in the figure) is a long strip structure made of stainless steel. One end is fixed to the top of the detection container 1, and the other end extends vertically upward from the measuring tube 2. The detection tube (not shown in the figure) is detachably fixed to the slider of the scale (not shown in the figure) by butterfly bolts. The slider can slide along the length of the scale (not shown in the figure). The outer wall of the detection tube (not shown in the figure) is provided with marking lines (not shown in the figure) to match the reading of the scale (not shown in the figure). The operator can calculate the water volume in the measuring tube 2 by using the scale value of the marking line (not shown in the figure) and the inner diameter of the measuring tube 2 (known parameter) through the cylinder volume formula, thereby adjusting the measuring tube 2 to the same capacity as the container to be tested.

[0028] The adjustment device 63 is installed on the mounting bracket 61 and can drive the camera device 64 to move in three directions: up and down, left and right, and forward and backward. The camera device 64 is an industrial camera with image recognition function. Its signal output terminal is connected to the controller in the control box 5 through a wire. When the identification line (not shown in the figure) on the detection tube (not shown in the figure) is aligned with the water level, a signal is sent to the control box 5 to shut down the peristaltic pump (not shown in the figure). The adjustment device 63 includes three sets of identical structural components: a vertical moving assembly 631, a horizontal moving assembly 632, and a front-back moving assembly 633. The vertical moving assembly 631 is bolted to the vertical beam of the mounting frame 61. The horizontal moving assembly 632 is bolted to the movable end of the vertical moving assembly 631. The front-back moving assembly 633 is bolted to the movable end of the horizontal moving assembly 632. The camera device 64 is fixed to the movable end of the front-back moving assembly 633 by a bracket. The three sets of components work together to achieve three-axis movement of the camera device 64: the vertical moving assembly 631 moves the camera device 64 vertically to adapt to the measuring tubes 2 at different heights; the horizontal moving assembly 632 moves the camera device 64 horizontally to align with the axis of the measuring tube 2; and the front-back moving assembly 633 moves the camera device 64 towards or away from the measuring tube 2 to achieve focusing.

[0029] Taking the up-and-down moving assembly 631 as an example, it includes a rack seat 6311 and a gear seat 6312 that meshes with the rack seat 6311. The rack seat 6311 has a long strip-shaped structure, and its two sides are provided with limiting platforms 63111 along the length direction to prevent the gear seat 6312 from falling off. A rack 63112 extending along the length direction is fixed at the center of the rack seat 6311 between the limiting platforms 63111. The gear seat 6312 has a U-shaped structure, and its inner side is provided with a gear (not labeled) that meshes with the rack 63112. A rotating wheel 63121 is fixed coaxially with the gear. One end of the rotating wheel 63121 is exposed on the outside of the gear seat 6312. The operator can rotate the rotating wheel 63121 to drive the gear to rotate, thereby driving the gear seat 6312 to move along the length of the rack seat 6311. The outer walls of the rack seat 6311 and the gear seat 6312 are also provided with corresponding scale lines (not shown in the figure). The scale lines (not shown in the figure) are made by laser engraving technology, and the moving distance of the gear seat 6312 can be precisely controlled by reading the scale value. The structures of the left-right moving component 632 and the front-back moving component 633 are exactly the same as those of the up-down moving component 631. The gear seat 6312 of the up-down moving component 631 is fixedly connected to the rack seat of the left-right moving component 632. The gear seat of the left-right moving component 632 is fixedly connected to the rack seat of the front-back moving component 633. The gear seat of the front-back moving component 633 is fixedly connected to the bracket of the camera device 64. The three-axis fine adjustment of the camera device 64 is achieved through the sequential connection of the three sets of components. The meshing force of the gears and racks can effectively prevent the camera device 64 from shifting during the water filling process.

[0030] The system works as follows: First, preparations are made before testing. The operator, based on the capacity of the container to be tested, loosens the butterfly bolt between the testing tube (not shown in the figure) and the scale (not shown in the figure), pushes the testing tube (not shown in the figure) to slide along the scale (not shown in the figure), and reads the scale value of the scale (not shown in the figure) through the marking line (not shown in the figure) on the testing tube (not shown in the figure). The water volume is calculated in conjunction with the inner diameter of the metering tube 2 until the water volume corresponding to the metering tube 2 matches the capacity of the container to be tested. Then, the butterfly bolt is tightened to fix the testing tube (not shown in the figure). Next, the adjustment device 63 is adjusted, and the up-and-down moving component 63 is rotated. The rotating wheel 63121 of the 1 controls the gear seat 6312 via the scale line (not shown in the figure) to drive the left and right moving component 632 to move up and down, so that the camera device 64 is roughly aligned with the height of the detection tube (not shown in the figure); then the rotating wheel of the left and right moving component 632 is rotated, and its gear seat is controlled via the scale line to drive the front and back moving component 633 to move left and right, so that the lens of the camera device 64 is aligned with the detection tube (not shown in the figure); finally, the rotating wheel of the front and back moving component 633 is rotated, so that the camera device 64 moves back and forth until the image of the detection tube (not shown in the figure) and the marking line (not shown in the figure) displayed on the display screen 52 is clear, and the focus is completed.

[0031] After the detection process is started, the controller in control box 5 first controls the water pump (not shown in the figure) to start. The water pump (not shown in the figure) quickly injects water into the detection container 1 through the pipeline. The flow meter (not shown in the figure) collects the water injection flow rate in real time and transmits the data to the controller. When the controller determines that the water level in the detection container 1 is close to the set water level (usually 90%-95% of the detection water level) based on the flow data, the controller shuts off the water pump (not shown in the figure) and simultaneously starts the peristaltic pump 4. The peristaltic pump (not shown in the figure) slowly injects water into the detection container 1 at a small flow rate to avoid the water level exceeding the tolerance due to rapid water injection. As the water level rises, the water level in the metering tube 2 rises synchronously. The camera device 64 continuously captures the water level image in the detection tube (not shown in the figure) and transmits it to the display screen 52. When the camera device 64 recognizes that the water level is aligned with the marking line (not shown in the figure) on the detection tube (not shown in the figure), it immediately sends an electrical signal to the controller in control box 5. After receiving the signal, the controller shuts off the peristaltic pump (not shown in the figure). The entire water injection detection process is completed. The entire process does not require operators to climb up to observe or manually operate, realizing automated detection.

[0032] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
