Description

Technical Field

[0001] This utility model belongs to the technical field of hydrological measurement equipment, specifically a device for automatically measuring hydrological elements in a river engineering model. Background Technology

[0002] In river engineering model tests, accurately obtaining hydrological data such as water level, flow velocity, flow rate, and sediment concentration is crucial for studying the laws of water flow, the characteristics of riverbed evolution, and assessing the impact of water conservancy projects on river channels.

[0003] However, traditional measurement methods mainly rely on manual operation, such as manually measuring flow velocity point by point using a current meter, measuring water level using measuring ropes and probes, and obtaining sediment content through laboratory analysis after sampling. This manual measurement method is not only inefficient and has a long measurement cycle, but also makes it difficult to guarantee the accuracy and reliability of the measurement data due to differences in human operation. At the same time, in some complex river engineering model scenarios, manual measurement has many inconveniences and may even be impossible.

[0004] To address this issue, those skilled in the art have proposed a device for automatically measuring hydrological elements in a river engineering model.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an automatic measurement device for hydrological elements in a river engineering model, thereby solving the problems that existing manual measurement methods are not only inefficient and have long measurement cycles, but also have difficulty in guaranteeing the accuracy and reliability of measurement data due to differences in human operation.

[0007] To achieve the above objectives, this utility model provides a device for automatically measuring hydrological elements in a river engineering model, including a base, multiple wheels symmetrically arranged on the side of the base, a column fixedly connected to the top of the base, a support column fixedly connected to the column, a connecting rod fixedly connected to the support column, a disassembly assembly provided at the end of the connecting rod, and an integrated sensor body provided on the disassembly assembly.

[0008] The assembly / disassembly assembly includes a fixing plate fixedly connected to the end of the connecting rod. The fixing plate has a sliding groove, and a Z-shaped locking block is slidably connected in the sliding groove. A protrusion is fixedly connected to the Z-shaped locking block, and a rotating component is provided on the fixing plate.

[0009] Preferably, the rotating component includes a turntable rotatably connected to a fixed plate, and the turntable has an arc-shaped groove.

[0010] Preferably, the top of the integrated sensor body is provided with a T-shaped groove, the protrusion is slidably connected in the arc-shaped groove, there are two Z-shaped blocks and two protrusions, which are symmetrically arranged, there are two arc-shaped grooves, which are evenly distributed around the circumference, and the ends of the two Z-shaped blocks are respectively engaged in the two ends of the T-shaped groove.

[0011] Preferably, the base is provided with a stabilizing component, which includes a motor fixedly connected to the column, a threaded rod fixedly connected to the output end of the motor, and a movable plate threadedly connected to the outside of the threaded rod.

[0012] Preferably, a pry bar is rotatably connected to the movable plate, a fixed rod is fixedly connected to the base, and a pestle is rotatably connected to the end of the pry bar.

[0013] Preferably, the threaded rod is rotatably connected to the base, the pry bar is rotatably connected to the fixed rod, and there are two pry bars, two fixed rods, and two symmetrically arranged insertion pins.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model significantly shortens measurement time and improves experimental efficiency by integrating a sensor body to synchronously collect hydrological data such as water level, flow velocity, flow rate, and sediment content in real time. It can acquire a large amount of data in a short time, meeting the data requirements of river engineering model experiments. Furthermore, by rotating the turntable, the two Z-shaped locking blocks are pushed to move in opposite directions under the squeezing force of the two arc-shaped grooves, thus removing the latches on the T-shaped grooves on the integrated sensor body and allowing the integrated sensor body to be disassembled. Conversely, by rotating the turntable in the opposite direction, the two Z-shaped locking blocks are locked into the T-shaped grooves on the integrated sensor body, completing the installation of the integrated sensor body. By setting up the disassembly and assembly components, the integrated sensor body can be quickly disassembled and assembled for maintenance or replacement.

[0016] 2. This utility model incorporates a motor that drives a threaded rod to rotate, causing a movable plate to move upwards on the threaded rod. The movable plate then drives two pry bars to rotate on a fixed rod, pressing down on the insertion pins and inserting them into the ground. This ensures that the device remains fixed in the river engineering model, thus avoiding measurement errors caused by device shaking or movement. A stable measurement environment helps improve the accuracy and reliability of the data, making the measurement results closer to the actual situation and providing more accurate data support for hydrological research.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0025] Example 1:

[0026] Please see Figure 1 - Figure 4As shown, a device for automatically measuring hydrological elements in a river engineering model includes a base 1. Multiple wheels 11 are symmetrically arranged on the sides of the base 1. A column 2 is fixedly connected to the top of the base 1, a support column 3 is fixedly connected to the column 2, and a connecting rod 4 is fixedly connected to the support column 3. A disassembly assembly 5 is provided at the end of the connecting rod 4, and an integrated sensor body 6 is mounted on the disassembly assembly 5. The base 1 supports the column 2, the wheels 11 rotate to move the entire assembly, the column 2 supports the support column 3, the support column 3 supports the connecting rod 4, and the connecting rod 4 supports... The assembly and disassembly unit 5 integrates the sensor body 6, which includes a non-contact laser water level sensor that accurately measures water level by emitting a laser beam and receiving reflected light, offering high precision and stability; an acoustic Doppler current profiler (ADCP) that uses the Doppler effect to measure water flow velocity at different depths, providing velocity profile information; an ultrasonic time-of-flight flow sensor that calculates flow rate by combining flow velocity and river cross-sectional area information; and an optical scattering sediment concentration sensor that determines sediment concentration by measuring the scattering characteristics of light in sediment-laden water. All sensors are calibrated and optimized to adapt to the complex flow environment of the river engineering model.

[0027] The assembly / disassembly component 5 includes a fixing plate 51 fixedly connected to the end of the connecting rod 4. The fixing plate 51 has a groove 52, and a Z-shaped locking block 53 is slidably connected in the groove 52. A protrusion 54 is fixedly connected to the Z-shaped locking block 53. A rotating component is provided on the fixing plate 51. The fixing plate 51 is used to support the rotating component. The groove 52 is used to guide the Z-shaped locking block 53. The Z-shaped locking block 53 is used to support the protrusion 54.

[0028] Specifically, the rotating component includes a turntable 55 rotatably connected to the fixed plate 51. The turntable 55 has an arc-shaped groove 56. When the turntable 55 rotates, it applies a pressing force to the protrusion 54 through the arc-shaped groove 56.

[0029] Furthermore, the top of the integrated sensor body 6 is provided with a T-shaped groove 61, the protrusion 54 is slidably connected in the arc groove 56, and there are two Z-shaped blocks 53 and two protrusions 54 arranged symmetrically. There are two arc grooves 56 arranged evenly around the circumference, and the ends of the two Z-shaped blocks 53 are respectively engaged in the two ends of the T-shaped groove 61.

[0030] As can be seen from the above, by setting the integrated sensor body 6 to collect hydrological data such as water level, flow velocity, flow rate, and sediment concentration in real time, the measurement time is greatly shortened and the experimental efficiency is improved. A large amount of data can be obtained in a short time, which meets the data requirements of the river engineering model experiment. Furthermore, by rotating the turntable 55, the two protrusions 54 on the two Z-shaped locking blocks 53 are slidably connected in the two arc-shaped grooves 56. Under the squeezing force of the two arc-shaped grooves 56, the two Z-shaped locking blocks 53 are pushed to move in opposite directions in the sliding groove 52, thus canceling the buckle on the T-shaped groove 61 on the integrated sensor body 6, so that the integrated sensor body 6 can be disassembled. Conversely, by rotating the turntable 55 in the opposite direction, the two Z-shaped locking blocks 53 are locked in the T-shaped groove 61 on the integrated sensor body 6, thus completing the installation of the integrated sensor body 6. By setting the disassembly and assembly component 5, the integrated sensor body 6 can be quickly disassembled and assembled for maintenance or replacement.

[0031] Example 2:

[0032] Please see Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that a stabilizing component 7 is provided on the base 1. The stabilizing component 7 includes a motor 71 fixedly connected in the column 2. A threaded rod 72 is fixedly connected to the output end of the motor 71. A movable plate 73 is threadedly connected to the outside of the threaded rod 72. The motor 71 is used to provide driving force to the threaded rod 72. The rotation of the threaded rod 72 drives the movable plate 73 to move on the threaded rod 72. The movable plate 73 is used to pry the pry bar 74 to rotate on the fixed rod 75.

[0033] Specifically, a pry bar 74 is rotatably connected to the movable plate 73, a fixed rod 75 is fixedly connected to the base 1, and a pestle 76 is rotatably connected to the end of the pry bar 74. The pry bar 74 is telescopic, the fixed rod 75 is used to support the pry bar 74, and the pestle 76 is used to insert into the ground.

[0034] Furthermore, the threaded rod 72 is rotatably connected to the base 1, and the pry bar 74 is rotatably connected to the fixed rod 75. There are two pry bars 74, two fixed rods 75, and two symmetrically arranged insertion rods 76.

[0035] As can be seen from the above, by setting up motor 71, since the output end of motor 71 is fixedly connected to threaded rod 72, motor 71 starts and drives threaded rod 72 to rotate. Since moving plate 73 is threadedly connected to the outside of threaded rod 72, the rotation of threaded rod 72 causes moving plate 73 to move upward on threaded rod 72. Moving plate 73 drives two pry bars 74 to rotate on fixed rod 75, thereby pressing the two pins 76 and inserting them into the ground, ensuring that the position of the device in the river engineering model remains fixed, thus avoiding measurement errors caused by device shaking or movement. A stable measurement environment helps to improve the accuracy and reliability of data, making the measurement results closer to the real situation and providing more accurate data support for hydrological research.
