Description

Technical Field

[0001] The present invention relates to the technical field of thickness measurement, in particular to a device for measuring the thickness of sea beach erosion and siltation. Background Art

[0002] The continuous action of the ocean and waves causes frequent erosion and siltation on beaches, which requires equipment to measure the thickness of beach erosion and siltation in the sea area. The equipment can accurately measure the changes in the thickness of beach erosion and siltation, and use the measurement data to more scientifically assess the ecological health of the coast and promptly discover potential ecological risks.

[0003] Existing automatic measuring instruments for tidal flat erosion and sedimentation thickness usually adopt a self-contained working mode, without the need for cumbersome cables and external power supplies. They rely on internally installed alkaline batteries for power supply, have extremely low power consumption, and can achieve long-term stable monitoring. The device has high-speed Bluetooth communication function, convenient data transmission, weighs about 450g, and uses the principle of echo detection to quantitatively measure the distance between the instrument and the substrate to reflect the erosion and sedimentation conditions of the substrate. It is usually installed on an external bracket, and then the bracket is installed in the appropriate measurement position.

[0004] However, in the existing technology, as the equipment is used for a longer time, the core components gradually wear out, resulting in a decrease in monitoring accuracy, or even exceeding the error range. It is difficult for staff to quickly determine whether the equipment has an error through conventional means. In addition, the equipment adopts a self-contained working mode and cannot quickly and remotely feedback its own status, which seriously affects the accuracy and reliability of the monitoring data. The main method currently is regular inspections, disassembly, and ground calibration. However, this process requires professional technicians to carry professional calibration tools to the equipment installation site. The disassembly process must also avoid causing secondary damage to the equipment. Since most equipment is deployed on remote beaches with complex environments and inconvenient transportation, and the measuring instrument is installed on top of the bracket, it is very inconvenient to disassemble. To facilitate the replacement and maintenance of the measuring equipment, some use foldable brackets. However, this type of bracket has many problems in actual use. Its structural stability is poor. In beach areas with strong sea breezes and frequent waves, it is extremely easy to shake or tilt due to external forces. Even slight shaking can interfere with the measurement accuracy of the sensor. In severe cases, it may even cause the equipment to fall and be damaged. After the calibration process, the equipment needs to be reinstalled to its original location, making it difficult to quickly and conveniently feedback its own status in real time.

[0005] To this end, a device for measuring the thickness of beach erosion and sedimentation in the sea area is proposed, which can remotely calibrate the measuring equipment to see if there is any problem, thereby ensuring the accuracy of the monitoring data. Summary of the Invention

[0006] The purpose of the present invention is to provide a device for measuring the thickness of beach erosion and sedimentation in a sea area, so as to solve the problem that the measuring device cannot quickly and remotely feedback its own status.

[0007] The technical solution of the present invention is: a device for measuring the thickness of beach erosion and sedimentation in a sea area, comprising a vertical pole, a bracket fixedly connected to the top of the vertical pole, a measuring device fixedly connected to the inside of the bracket, a scraper arranged on the outside of the measuring device, a driving member fixedly connected to the inside of the bracket, a transmission rod fixedly connected to the output end of the driving member, two rocking arms provided and connected to both sides of the bracket, a sheath fixedly connected to the bottom end of the rocking arm, and a circular plate rotatably connected to the inside of the sheath, the two sides of the transmission rod are located inside the rocking arm, the transmission rod is in an initial position when the driving member is fully retracted, the bottom surface of the measuring device is processed by the scraper when the transmission rod moves downward, and the rocking arm and the circular plate are squeezed when the transmission rod moves downward, so that the circular plate rotates to the bottom of the measuring device and is parallel to the bottom surface of the measuring device.

[0008] Furthermore, the bracket includes a sleeve frame fixedly connected to the vertical rod, a guard plate fixedly connected to the top of the sleeve frame, and two straight plates fixedly connected to both sides of the sleeve frame, and arc grooves are opened on the straight plates.

[0009] Furthermore, the rocker is divided into a straight section and an oblique section. A round block is provided on one side of the rocker close to the bracket. A straight slot is provided on the rocker. A spring is connected between the round block and the straight plate.

[0010] Furthermore, the round block is always located inside the arc notch, and the arc notch is concentric with the top end of the straight notch.

[0011] Furthermore, a vertical groove is provided in the middle of the sheath, a torsion spring is connected between the sheath and the circular plate, and a side of the circular plate close to the sheath is arc-shaped.

[0012] Furthermore, the transmission rod includes a round rod fixedly connected to the output end of the driving member, two pressure rods fixedly connected to both sides of the round rod, an arc block fixedly connected to the bottom end of the round rod, and a convex strip fixedly connected to the outside of the round rod, the pressure rod is located inside the straight slot, the pressure rod is always in contact with the inner wall of the straight slot, and the bottom surface of the arc block is an arc surface away from the round rod.

[0013] Furthermore, the scraping member includes a circular sleeve fixedly mounted on the outside of the measuring device, a circular shaft rotatably connected to the inside of the circular sleeve, and an arc scraping strip fixedly connected to the bottom end of the circular shaft. A guide groove is provided on the circular shaft, and a guard ring is provided on the surface of the measuring device. The guard ring is located directly above the arc scraping strip, and the bottom of the guide groove is vertical.

[0014] Furthermore, the contact surface between the circular sleeve and the circular shaft is treated with high friction, and when the circular rod is initially positioned, the convex strip is located inside the guide groove, and the pressure rod is concentric with the arc groove opening.

[0015] Furthermore, the width of the arc block is equal to the width of the vertical groove, both sides of the arc block and the inner wall of the vertical groove are located in the same plane, and the center lines of the convex strip and the arc block coincide with each other.

[0016] Furthermore, the driving member includes a telescope fixedly connected to the inside of the sleeve frame, and an accumulator fixedly connected to the inside of the telescope, and the guard plate is located directly above the accumulator.

[0017] Beneficial effects of the present invention:

[0018] When the transmission rod moves downward, the scraper is first used to clean the bottom of the measuring device, which greatly improves the accuracy and stability of the measuring device in measuring the thickness of beach erosion and sedimentation, and provides a reliable data basis for related research. The circular plate is then squeezed to the bottom of the measuring device to provide real-time feedback on the distance between the measuring device and the circular plate, which can be compared with the data recorded during the initial installation. This allows the working status of the measuring device to be quickly determined, problems to be discovered and measures to be taken in a timely manner, without the need for staff to visit the site in person. It is quick and convenient and does not require disassembly.

[0019] 2. A single drive member is used as the drive, and the device can remotely control the contraction of the drive member, thereby controlling the up and down movement of the transmission rod, so as to quickly judge the working status of the measuring instrument. This not only reduces the complexity and potential errors in the calibration process, but also can be quickly integrated with existing equipment, improving the convenience and efficiency of operation, reducing the failure rate of the equipment, and ensuring the continuity of monitoring data, thereby improving the reliability of the entire equipment, greatly improving the convenience of operation, and saving manpower and time costs.

[0020] The rocker is pushed to rotate by moving the transmission rod downward to squeeze it, thereby reducing the electronic control equipment. The squeezing force allows the transmission structure of the equipment to maintain good working performance during long-term and frequent calibration operations. At the same time, the scraper is also rotated by the downward squeezing of the transmission rod, thereby cleaning the bottom of the measuring instrument. This ensures that the structure is stable and not prone to loosening or displacement during long-term scraping operations, ensuring the continued effectiveness of the scraping function and further improving the durability of the equipment in marine environments.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1-9, an embodiment of the present invention provides a device for measuring the thickness of beach erosion and sedimentation in a sea area, comprising a vertical pole 1, a bracket 2 fixedly connected to the top of the vertical pole 1, a measuring device 3 fixedly connected to the inside of the bracket 2, a scraping member 4 arranged outside the measuring device 3, a driving member 5 fixedly connected to the inside of the bracket 2, a transmission rod 6 fixedly connected to the output end of the driving member 5, two rocking arms 7 connected to both sides of the bracket 2, a sheath 8 fixedly connected to the bottom end of the rocking arm 7, and a circular plate 9 rotatably connected to the inside of the sheath 8, both sides of the transmission rod 6 are located inside the rocking arm 7, and the driving member 5 is fully retracted. The time-delayed transmission rod 6 is in the initial position. When the transmission rod 6 moves downward, the bottom surface of the measuring device 3 is processed by the scraper 4. When the remote control transmission rod 6 moves downward, the rocker 7 and the circular plate 9 are squeezed, so that the circular plate 9 rotates to the bottom of the measuring device 3 and is parallel to the bottom surface of the measuring device 3. The distance between the measuring device 3 and the circular plate 9 is known data, that is, it is used and recorded when the equipment is first installed. The distance when the circular plate 9 is located directly below the measuring device 3 and parallel to the bottom surface of the measuring device 3. At this time, the feedback distance of the measuring device 3 is compared with the recorded data. If it does not exceed the error range, it means that the measuring device 3 does not need maintenance.

[0034] Specifically, the drive member 5 can be remotely controlled, eliminating the need for staff to personally visit the equipment installation site. By controlling the extension and retraction of the drive member 5, the upward and downward movement of the transmission rod 6 is controlled. During the downward movement of the transmission rod 6, the scraper 4 can clean the bottom surface of the measuring instrument 3. Since the measuring instrument 3 is located in a complex marine environment, impurities such as mud and sand are easily attached to the bottom surface of the measuring instrument 3, which can affect the measurement accuracy. The scraper 4 can promptly remove these interfering factors, ensuring that the measuring instrument 3 is always in good working condition and improving the accuracy and stability of the measurement. At the same time, during the downward movement of the transmission rod 6, the circular plate 9 rotates to be directly below the measuring instrument 3 and parallel to the bottom surface of the measuring instrument 3. At this time, the value fed back by the measuring instrument 3 is the distance between the circular plate 9 and the measuring instrument 3. By comparing this data with the initial measurement data of the distance between the measuring instrument 3 and the circular plate 9, it is possible to quickly determine whether there is a problem with the measuring equipment and take corresponding measures to ensure the continuity of monitoring work and the reliability of data, making the maintenance process of the entire equipment more convenient. The ability to perform remote calibration reduces the frequency of on-site maintenance, reduces the difficulty and complexity of maintenance work, and improves maintenance efficiency.

[0035] Among them, when the rocker 7 is not squeezed by the transmission rod 6, it is tilted. At this time, the circular plate 9 will be away from the bottom of the measuring device 3, so as to avoid the circular plate 9 affecting the measurement feedback of the measuring device 3 in the normal state.

[0036] Reference Figure 1-Figure 5The bracket 2 includes a sleeve frame 21 fixedly connected to the vertical rod 1, a guard plate 22 fixedly connected to the top of the sleeve frame 21, and two straight plates 23 fixedly connected to both sides of the sleeve frame 21. The straight plates 23 are provided with arc grooves 231. The guard plate 22 is fixed to the top of the sleeve frame 21 to provide certain protection for the driving component 5 and ensure long-term stable operation of the equipment.

[0037] The rocker 7 is divided into a straight section 701 and an oblique section 702. A round block 71 is provided on the side of the rocker 7 close to the bracket 2. A straight slot 72 is opened on the rocker 7. The round block 71 is always located inside the arc slot 231. The arc slot 231 is concentric with the top of the straight slot 72. A spring 232 is connected between the round block 71 and the straight plate 23. The round block 71 is located at the top of the oblique section 702, and the transmission rod 6 is located inside the straight slot 72.

[0038] Specifically, the straight section 701 and the oblique section 702 of the rocker 7 will squeeze the inner wall of the straight slot 72 when the transmission rod 6 moves downward. At this time, after the rocker 7 is squeezed by the transmission rod 6, the round block 71 on its oblique section 702 is subjected to force. Since the round block 71 is always located inside the arc slot 231, and the arc slot 231 is concentric with the top of the straight slot 72, the rocker 7 will also rotate with this as the center of the circle, thereby making the rocker 7 rotate under the stable guiding action. During the rotation of the rocker 7, the round block 71 slides along the trajectory of the arc slot 231 and the straight slot 72. At the same time, the round block 71 will stretch the spring 232, ensuring the stability and accuracy of the rotation of the rocker 7, avoiding shaking or deviation, and further ensuring the accuracy of the rotation positioning of the circular plate 9, and can push the rocker 7 to rotate around a point at a specific angle, thereby driving the sheath 8 and the circular plate 9 to rotate. This precise transmission method ensures that the circular plate 9 can be accurately rotated to the position directly below the measuring device 3. After the device completes calibration and other operations, the spring 232 can provide a reset force to help the rocker 7 return to its initial position quickly and smoothly, allowing the device to efficiently switch back to normal working state, thereby improving the device's working efficiency.

[0039] Reference Figure 2-Figure 5 A vertical slot 81 is provided in the middle of the sheath 8, a torsion spring 801 is connected between the sheath 8 and the circular plate 9, and the side of the circular plate 9 close to the sheath 8 is arc-shaped.

[0040] Specifically, the arc surface of the circular plate 9 will contact the transmission rod 6, and then after the two come into contact, the transmission rod 6 will continue to move downward to squeeze the circular plate 9, and finally the top surface of the circular plate 9 will be parallel to the bottom surface of the measuring device 3. At this time, the circular plate 9 will rotate at the connection point with the sheath 8, and at the same time, the torsion spring 801 will be rotationally compressed during the rotation. When the transmission rod 6 moves back, the torsion spring 801 will rebound quickly to generate potential energy, pushing the circular plate 9 back to its initial position quickly and accurately, thereby using the sheath 8 to protect the circular plate 9.

[0041] Reference Figure 2-Figure 7The transmission rod 6 includes a round rod 61 fixedly connected to the output end of the driving member 5, and is provided with two pressure rods 62 fixedly connected to both sides of the round rod 61, an arc block 63 fixedly connected to the bottom end of the round rod 61, and a convex strip 64 fixedly connected to the outside of the round rod 61. The pressure rod 62 is located inside the straight slot 72, and the pressure rod 62 always fits with the inner wall of the straight slot 72. When the pressure rod 62 moves down with the round rod 61, the straight slot 72 is inclined, and the pressure rod 62 squeezes the inner wall of the straight slot 72, and the rocker 7 is guided by the arc slot 231 and then rotates, but the pressure rod 62 is not at the center of the rotation circle at this time, and the rocker 7 cannot rotate, and the bottom surface of the arc block 63 is an arc surface away from the round rod 61, and the width of the arc block 63 is 200. The degree is equal to the width of the vertical groove 81. The two sides of the arc block 63 are in the same plane as the inner wall of the vertical groove 81. The center lines of the convex strip 64 and the arc block 63 coincide with each other. The arc block 63 will enter the vertical groove 81, and then the arc surface of the arc block 63 will squeeze the arc surface of the circular plate 9. At the same time, there is a horizontal surface at the bottom of the arc block 63. When the transmission rod 6 moves downward with the action of the driving member 5, the arc block 63 will smoothly enter the vertical groove 81. At this time, the arc surface of the arc block 63 interacts with the arc surface of the circular plate 9 to push the circular plate 9 to rotate. When the driving member 5 is fully extended, the horizontal surface of the bottom of the arc block 63 will fit tightly with the circular plate 9, so that the circular plate 9 can be adjusted to a horizontal state and is located directly below the measuring device 3. At this time, the distance between the two can be obtained.

[0042] Specifically, the round rod 61 is firmly fixed to the output end of the driving member 5, the pressure rod 62 is located inside the straight slot 72, and always maintains a close fit with the inner wall of the straight slot 72. When the round rod 61 is in the initial position, it moves downward under the action of the driving member 5. At this time, the straight slot 72 is inclined, and the pressure rod 62 will produce a continuous and stable extrusion pressure on its inner wall. While the rocker 7 is subjected to the extrusion pressure of the pressure rod 62, it is guided by the arc slot 231 and begins to rotate. After the pressure rod 62 moves, it will not be at the center position of the rotation of the rocker 7, which effectively prevents the rocker 7 from rotating accidentally, ensuring that the rotation of the rocker 7 is always guided during the operation of the equipment, thereby ensuring the stability and accuracy of the equipment operation.

[0043] In addition, the convex strip 64 fixedly connected to the outside of the round rod 61 coincides with the center line of the arc block 63. The existence of the convex strip 64 increases the structural stability of the transmission rod 6 during operation. At the same time, both can pass through the vertical slot 81 without collision and friction. The pressure rod 62 squeezes the straight slot 72 and the arc block 63 pushes the circular plate 9, ensuring that the circular plate 9 can be accurately rotated to the bottom of the measuring device 3 and maintain a horizontal state, thereby improving the accuracy of the calibration of the measuring device 3. At the same time, the integrated structure of the transmission rod 6 enables the equipment to better adapt to the complex and changeable beach environment and ensure the stable transmission between the various components of the equipment.

[0044] Reference Figure 2-Figure 8 The scraper 4 includes a circular sleeve 41 fixedly sleeved on the outside of the measuring instrument 3, a circular shaft 42 rotatably connected to the inside of the circular sleeve 41, and an arc scraping strip 43 fixedly connected to the bottom end of the circular shaft 42. A guide groove 421 is provided on the circular shaft 42. The outer surface of the measuring instrument 3 is provided with a protective ring 31, which is located just above the arc scraping strip 43 and can provide additional protection for the arc scraping strip 43. The bottom of the guide groove 421 is vertical, so that the convex strip 64 can more accurately enter the guide groove 421 when it moves back, so that the circular shaft 42 drives the arc scraping strip 43 to rotate. The contact surface between the circular sleeve 41 and the circular shaft 42 is treated with high friction to ensure that the circular shaft 42 will not easily slide or stop rotating when it is not subjected to a large external force, thereby ensuring the normal performance of the scraping work. In addition, a conventional buckle limiter is provided between the circular shaft 42 and the circular sleeve 41, so that the circular shaft 42 can only rotate ninety degrees.

[0045] Specifically, the circular sleeve 41 is fixedly sleeved on the outside of the measuring instrument 3, providing a stable installation foundation, ensuring that the circular shaft 42 can rotate, and at the same time ensuring its stability during the rotation process. When the round rod 61 moves downward, the protrusion 64 will move in the guide groove 421, thereby causing the circular shaft 42 to rotate. At this time, the arc scraper 43 rotates accordingly to clean the bottom surface of the measuring instrument 3, effectively removing various impurities such as mud and sand attached to the bottom surface of the measuring instrument 3.

[0046] When the round rod 61 is initially positioned, the ridge 64 is located inside the guide groove 421, and the pressure rod 62 is concentric with the arc groove opening 231. At this time, the ridge 64 drives the round shaft 42 and the arc scraper 43 to rotate synchronously with the round rod 61, and the pressure rod 62 will not block the rocker 7 at this time, and the rocker 7 can rotate. However, when the pressure rod 62 moves downward, the centers of the two circles no longer coincide, making it impossible for the rocker 7 to rotate.

[0047] Reference Figures 1-9 The driving part 5 includes a telescope 51 fixedly connected to the inside of the sleeve frame 21, and a battery 52 fixedly connected to the inside of the telescope 51. The protective plate 22 is located directly above the battery 52. ​​The exterior adopts a waterproof structure. At the same time, a remote controller is set in the telescope 51 for remote control. The controller has a wireless remote control function, is waterproof, and can adapt to various complex sea environments.

[0048] The working principle of the present invention is as follows: the telescopic device 51 is controlled to extend and retract. When the telescopic device 51 is extended, the round rod 61 moves downward. When the telescopic device 51 is contracted, the round rod 61 moves upward. When the transmission rod 6 moves downward from the initial position, the convex strip 64 on the outside of the round rod 61 will move in the guide groove 421, so that the round shaft 42 is compressed, and then the round shaft 42 rotates. The rotation of the round shaft 42 drives the arc scraper 43 to rotate, cleaning the bottom surface of the measuring device 3, effectively removing impurities such as attached mud and sand, ensuring the cleanliness of the bottom surface of the measuring device 3, and improving the measurement accuracy. The round rod 61 continues to move downward, and the pressure rods 62 on both sides are located inside the straight slot 72 and are always in contact with the inner wall of the straight slot 72. At this time, due to the inclination of the straight slot 72, the pressure rod 62 squeezes the inner wall of the straight slot 72 when moving downward, and the rocker 7 starts to move under the action of the squeezing force, and the round block 71 is always located in the arc slot 231 on the straight plate 23 of the bracket 2 At the same time, the arc notch 231 is concentric with the top of the straight notch 72, so that the rocker 7 rotates around this center of the circle, and the round block 71 slides along the trajectory of the arc notch 231 and the straight notch 72 and stretches the spring 232, driving the circular plate 9 fixed in the sheath 8 at the bottom end of the rocker 7 to rotate, and the arc block 63 will then enter the vertical groove 81, and the arc surface of the arc block 63 squeezes the arc surface of the circular plate 9, pushing the circular plate 9 to rotate further. When the driving member 5 is fully extended, the horizontal surface of the bottom of the arc block 63 fits with the circular plate 9, so that the circular plate 9 is horizontal and located directly below the measuring device 3. The measuring device 3 feeds back the distance from the circular plate 9 in real time. The staff compares this real-time data with the initial recorded data. If it is within the error range, it indicates that the measuring device 3 is working normally and no maintenance is required; if it exceeds the error range, problems with the equipment can be discovered in time so that corresponding measures can be taken to ensure the continuity of monitoring work and the reliability of data;

[0049] After the measurement and maintenance judgment are completed, the telescopic device 51 is controlled to retract, the transmission rod 6 moves up, the convex strip 64 moves back, the guide shaft 42 drives the arc scraper 43 to rotate, and the pressure rod 62 moves up synchronously. The rocker 7 is reset synchronously under the reset force of the spring 232, and the circular plate 9 is also reset under the rebound potential energy of the torsion spring 801 after losing the extrusion, so that the circular plate 9 and the sheath 8 are spliced ​​together, and the equipment enters the standby state, waiting for the next work instruction.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
