Description

Technical Field

[0001] The invention relates to the technical field of thickness measurement, and 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 bottom to reflect the erosion and sedimentation of the bottom. It is usually installed on an external bracket, and then the bracket is installed in the appropriate measurement position.

[0004] However, in the prior art, as the use time of the equipment increases, the core components gradually wear out, resulting in a decrease in monitoring accuracy, or even exceeding the error range. It is difficult for the staff to quickly determine whether the equipment has an error through conventional means, and the equipment adopts a self-contained working mode, and cannot quickly remotely feedback its own status, resulting in serious impact on the accuracy and reliability of the monitoring data. The main method at present is regular inspection, disassembly, and ground calibration, but this process requires professional technicians to carry professional calibration tools to the equipment installation site, and secondary damage to the equipment must be avoided during the disassembly process. Since most of the equipment is deployed on remote beaches, the environment is complex and the transportation is inconvenient, and the measuring device is installed above the bracket, it is very inconvenient to disassemble. In order to facilitate the replacement and maintenance of the measuring equipment, some foldable brackets are used. However, this type of bracket has many problems in actual use, and its structural stability is poor. In the beach area with strong sea breeze and frequent wave impact, it is very easy to shake or tilt due to external force. Slight shaking will interfere with the measurement accuracy of the sensor, and even cause the equipment to fall and be damaged in severe cases. After the calibration process, the equipment needs to be reinstalled to the original location, and it is 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 siltation in the sea area is proposed, which can remotely calibrate whether there is any problem with the measuring equipment to ensure 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 siltation in a sea area, so as to solve the problem that the measuring device cannot quickly and remotely feedback its own status.

[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 formed on the straight plates.

[0009] Furthermore, the rocker is divided into a straight section and an inclined section, a round block is arranged on one side of the rocker close to the bracket, a straight slot is opened on the rocker, and 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 sleeve, a torsion spring is connected between the sleeve and the circular plate, and a side of the circular plate close to the sleeve 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 sleeved 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 round sleeve and the round shaft is subjected to high friction treatment, and when the round rod is initially located, 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, the two 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.

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

[0017] Beneficial effects of the present invention: When the transmission rod moves downward, the bottom of the measuring device is first cleaned with a scraper, which greatly improves the accuracy and stability of the measuring device in measuring the thickness of beach erosion and siltation, providing 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 for the first installation. This can quickly determine the working status of the measuring device, identify problems in time and take measures without the need for staff to visit the site. It is quick and convenient and does not require disassembly.

[0018] 2. A single drive is used as the drive, and the device can remotely control the contraction of the drive, thereby controlling the up and down movement of the transmission rod, so as to quickly determine the working status of the measuring device.

[0019] 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 to maintain good working performance during long-term and frequent calibration operations. At the same time, the scraper is also squeezed and rotated by the downward movement of the transmission rod, thereby cleaning the bottom of the measuring device. This ensures that the structure is stable and not prone to loosening or displacement during long-term scraping operations, ensuring that the scraping function is continuously effective and further improving the durability of the equipment in marine environments.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1-Figure 9 , is an embodiment of the present invention, and provides a device for measuring the thickness of beach erosion and sedimentation in a sea area, comprising a vertical rod 1, a bracket 2 fixedly connected to the top of the vertical rod 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 completely retracted. When the transmission rod 6 is extended, it is located 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 transmission rod 6 moves downward under remote control, 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 is 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.

[0024] Specifically, the driving member 5 can be remotely controlled, and the staff does not need to go to the equipment installation site in person. By controlling the extension and contraction of the driving member 5, the upward and downward movement of the transmission rod 6 can be controlled. During the downward movement of the transmission rod 6, the bottom surface of the measuring device 3 can be cleaned by relying on the scraper 4. Since the measuring device 3 is located in a complex marine environment, the bottom surface of the measuring device 3 is easily attached with mud and other impurities, which will affect the measurement accuracy. The scraper 4 can timely remove these interference factors to ensure that the measuring device 3 is always in a good working state and improve the measurement accuracy and stability. At the same time, during the downward movement of the transmission rod 6, the circular plate 9 will rotate to the bottom of the measuring device 3 and be parallel to the bottom surface of the measuring device 3. At this time, the value fed back by the measuring device 3 is the distance between the circular plate 9 and the measuring device 3. By comparing this data with the measurement data of the distance between the measuring device 3 and the circular plate 9 for the first time, it is possible to quickly determine whether there is a problem with the measuring equipment, take corresponding measures to ensure the continuity of the monitoring work and the reliability of the data, making the maintenance process of the entire equipment more convenient, and 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.

[0025] When the rocker arm 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 a normal state.

[0026] Reference Figure 1-Figure 5 The 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 member 5 and ensure long-term stable operation of the equipment.

[0027] The rocker 7 is divided into a straight section 701 and an inclined 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 inclined section 702, and the transmission rod 6 is located inside the straight slot 72.

[0028] 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 the 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, thereby 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 bottom of the measuring device 3. After the equipment completes calibration and other operations, the spring 232 can provide a reset force to help the rocker 7 return to the initial position quickly and smoothly, so that the equipment can efficiently switch back to normal working state, thereby improving the working efficiency of the equipment.

[0029] Reference Figure 2-Figure 5 A vertical groove 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.

[0030] 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 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 the initial position quickly and accurately, thereby using the sheath 8 to protect the circular plate 9.

[0031] Reference Figure 2-Figure 7The transmission rod 6 includes a round rod 61 fixedly connected to the output end of the driving member 5, 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 is always in contact with the inner wall of the straight slot 72. When the pressure rod 62 moves downward 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 located at the center of the rotation circle at this time, so 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 The arc block 63 has a width equal to that of the vertical groove 81, and both sides of the arc block 63 are located in the same plane as the inner wall of the vertical groove 81, and the center lines of the convex strip 64 and the arc block 63 coincide with each other, and 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, and 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, and when the driving member 5 is fully extended, the horizontal surface at 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.

[0032] Specifically, the round rod 61 is firmly fixed at the output end of the driving member 5, the pressure rod 62 is located inside the straight slot 72, and always keeps 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 squeezing pressure on its inner wall. While the rocker 7 is subjected to the squeezing 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 of the rotation of the rocker 7, which effectively prevents the rocker 7 from accidentally rotating, 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.

[0033] 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 of them can pass through the vertical groove 81 without causing collision and friction. The compression of the straight groove 72 by the pressure rod 62 and the push of the circular plate 9 by the arc block 63 ensure 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.

[0034] Reference Figure 2-Figure 8 The scraper 4 includes a circular sleeve 41 fixedly sleeved on the outside of the measuring device 3, a circular shaft 42 rotatably connected to the inside of the circular sleeve 41, and an arc scraper strip 43 fixedly connected to the bottom end of the circular shaft 42. A guide groove 421 is provided on the circular shaft 42. A guard ring 31 is provided on the outer surface of the measuring device 3. The guard ring 31 is located directly above the arc scraper strip 43, which can provide additional protection for the arc scraper strip 43. The bottom of the guide groove 421 is vertical, so that the convex strip 64 can more accurately enter the inside of the guide groove 421 when moving back, so that the circular shaft 42 drives the arc scraper 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.

[0035] Specifically, the circular sleeve 41 is fixedly sleeved on the outside of the measuring device 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 convex strip 64 will move in the guide groove 421, thereby causing the circular shaft 42 to rotate. At this time, the arc scraper strip 43 rotates accordingly to clean the bottom surface of the measuring device 3, effectively removing various impurities such as mud and sand attached to the bottom surface of the measuring device 3.

[0036] When the round rod 61 is initially located, the convex strip 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 convex strip 64 will drive the round shaft 42 and the arc scraper strip 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, so that the rocker 7 cannot rotate.

[0037] Reference Figure 1-Figure 9 The driving member 5 includes a retractor 51 fixedly connected to the inside of the sleeve frame 21, and a battery 52 fixedly connected to the inside of the retractor 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 arranged in the retractor 51 for remote control. The JIUYING controller can perform wireless remote control function, is waterproof, and can adapt to a variety of complex sea environments.

[0038] 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 outside 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 strip 43 to rotate, and the bottom surface of the measuring device 3 is cleaned, and the attached mud and other impurities are effectively removed to ensure the cleanliness of the bottom surface of the measuring device 3 and improve 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 with this center, 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 of the rocker 7 to rotate, and the arc block 63 will 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 with 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, the problem of the equipment can be discovered in time so that corresponding measures can be taken to ensure the continuity of the monitoring work and the reliability of the data; When 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 circular shaft 42 drives the arc scraper strip 43 to rotate, and the pressure rod 62 moves up synchronously. The rocker arm 7 is reset synchronously under the action of the reset force of the spring 232, and the circular plate 9 is also reset under the action of the rebound potential energy of the torsion spring 801 after losing the extrusion, so that the circular plate 9 and the sleeve 8 are spliced, and the equipment enters the standby state, waiting for the next work instruction.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. 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.
