Description

Technical Field

[0001] The present invention relates to the technical field of shoreline measurement devices in beaches, and in particular, to a shoreline erosion and deposition evolution measurement device in beach restoration tests. Background Art

[0002] The measurement technology of shoreline erosion and deposition evolution in beaches has played an important role in coastal management and disaster prevention and reduction. In recent years, with the application of advanced measurement means such as remote sensing technology, unmanned aerial vehicles, and lidar, this field has developed significantly. These technologies can efficiently and accurately obtain shoreline changes and sediment dynamics, provide real-time data support, and help researchers and managers analyze the trends of shoreline erosion and deposition. Through the comparison of historical data and model simulations, researchers can predict future shoreline evolution and formulate corresponding protection and governance measures.

[0003] The current shoreline erosion and deposition evolution measurement devices in beaches are constantly advancing in technology, but there are still some limitations in actual applications. For example, when measuring underwater topography, especially sedimentation measurement and cross-section measurement, the measurement device needs to be able to move. Traditional measurement devices are divided into coastal fixed-type and ship-mounted type. The coastal fixed-type measurement device consists of a base and a high-precision scanning device, which is fixed near the coast and cannot move. If mobile measurement is required, a ship needs to carry a high-precision scanning device to perform regular fixed-point measurement operations;

[0004] The measurement ranges of the above two types are limited and their functions are relatively single. How to combine mobile measurement and fixed-point measurement into one is a problem that we need to solve. Summary of the Invention

[0014] In a preferred solution, the top of the fixing tube is fixedly connected with a connecting rod, and the other end of the limiting rope is a first fixing rod. The tops of the first fixing rod and the connecting rod are respectively provided with rings, and the rings are convenient for carrying.

[0015] In a preferred embodiment, the motion mechanism includes a direction motor fixedly connected to the inner wall of the bottom of the detector body. One end of the output shaft of the direction motor is fixedly connected to a motion motor. One end of the output shaft of the motion motor is fixedly connected to a propeller.

[0024] Third: During the process of the sea waves rising and falling, the sea waves will drive the buoyancy cylinder to rise and fall. The up and down movement of the buoyancy cylinder drives the mounting rod to rotate, thereby driving the piston to slide inside the rotating cylinder, squeezing the air between the rotating cylinder and the piston, and discharging the air into the sea water or sucking in sea water through the air duct, achieving the effect of buffering the shaking of the detector body by the sea waves. At the same time, the bubbles discharged through the air duct can drive away fish, achieving the effect of reducing the influence of fish on the detection of the beach stratum.

[0038] A motion mechanism is installed at the bottom of the detector body 1, and the motion mechanism is used to drive the detector body 1 to move, and cooperate with the fixed point mechanism to stabilize the position of the detector body 1;

[0039] A fixing mechanism is installed on the bottom edge of one side of the detector body 1, and the fixing mechanism is used to fix the position of the detector body 1;

[0040] Buoyancy mechanisms are installed on both sides of the bottom of the detector body 1, and the buoyancy mechanisms are used to provide buoyancy and reduce the shaking of the detector body 1 caused by waves.

[0041] Among them, the radar detector 11 can emit sound wave pulses vertically downward, measure the time from the emission to the reflection and return of the sound wave from the bottom of the water, calculate the water depth in combination with the speed of sound, and form single-point vertical section data, which is suitable for shallow water areas or local refined measurements, and needs to cooperate with the movement of the motion mechanism to achieve continuous section coverage. This is the existing technology.

[0042] Specifically, the limiting rope 4 passes between the auxiliary wheel 26 and the main wheel 28, and the spacing between the multiple toggle bars 27 is greater than the diameter of the friction ball 29. The buoyancy of the friction ball 29 makes the limiting rope 4 float on the water surface, which facilitates the relative rotation of the auxiliary wheel 26 and the main wheel 28, and the friction ball 29 can be stably toggled to drive the limiting rope 4 to move.

[0043] Furthermore, mounting plates 39 are provided on both sides of the detector body 1, and a three-dimensional laser scanner can be installed on the surface of the mounting plate 39 for high-precision and rapid acquisition of the coastline terrain to ensure the measurement point accuracy and coverage density. Other acquisition equipment such as a wind vane can also be installed. This is the existing technology and will not be repeated here.

[0044] The fixed-point mechanism includes a release roller 38 fixedly connected to one end of the limiting rope 4, the top of the release roller 38 is fixedly connected to a release motor 37, the bottom of the release motor 37 is fixedly connected to a fixed cylinder 3, an auxiliary controller 35 is fixedly connected to the outer wall of one side of the fixed cylinder 3, the top of the fixed cylinder 3 is rotatably connected to an auxiliary antenna 36, ​​the bottom of the fixed cylinder 3 is fixedly connected to a second fixed rod 12, the auxiliary controller 35 is electrically connected to the main controller 15 through the auxiliary antenna 36, ​​and the main controller 15 is electrically connected to the mobile motor 16 and the main antenna 17 respectively, for transmitting the collected information to the terminal. This is the prior art and will not be repeated here.

[0045] The top of the fixing tube 3 is fixedly connected with a connecting rod 13, and the other end of the limiting rope 4 is a first fixing rod 7. The tops of the first fixing rod 7 and the connecting rod 13 are respectively provided with rings, which are convenient for carrying;

[0046] Furthermore, the first fixing rod 7 and the second fixing rod 12 can be provided in multiple groups, or in a forked structure, etc., to ensure the stability of insertion into the sand, and the length of the limiting rope 4 is selected according to the required detection range.

[0047] The motion mechanism includes a direction motor 10 fixedly connected to the inner wall of the bottom of the detector body 1. One end of the output shaft of the direction motor 10 is fixedly connected to a motion motor 8. One end of the output shaft of the motion motor 8 is fixedly connected to a propeller 9. The outside of the motion motor 8 is sealed to isolate seawater.

[0048] The motion motor 8 and the direction motor 10 are respectively electrically connected to the main controller 15. The direction motor 10 is located at the central position inside the detector body 1. The connection part of the direction motor 10 and the bottom of the detector body 1 is sealed to isolate seawater.

[0049] The fixing mechanism includes a fixing box 22 fixedly connected to the bottom edge of one side of the detector body 1. A first sliding cylinder 21 is fixedly connected inside the fixing box 22. A second sliding cylinder is slidably connected inside the first sliding cylinder 21. A third sliding cylinder is slidably connected inside the second sliding cylinder. A fourth sliding cylinder is slidably connected inside the third sliding cylinder. A fifth sliding cylinder 23 is slidably connected inside the fourth sliding cylinder.

[0050] A anchor nail 24 is fixedly connected to the bottom of the fifth sliding cylinder 23. There are multiple auxiliary sliding cylinders. An air pump 19 is fixedly connected to the inner wall of the top of the detector body 1 near the position of the first sliding cylinder 21. A connecting pipe 25 is inserted at the bottom of the air pump 19. One end of the connecting pipe 25 is connected to the first sliding cylinder 21. Multiple air inlets 20 are arranged on the upper surface of the detector body 1 near the air pump 19.

[0051] In this embodiment, in the shoal, the sea water is shallow. In order to detect the bottom layer of the beach, it is necessary to detect at various positions in the shoal. Boats cannot be used in the shoal, and manual detection is inefficient. By fixing the fixing cylinder 3 on the beach beside the shoal, inserting the first fixing rod 7 into the beach at a certain distance from the fixing cylinder 3, one end of the limiting rope 4 passes through the middle of the auxiliary wheel 26 and the main wheel 28, one end of the limiting rope 4 is wound on the release roller 38, the other end of the limiting rope 4 is fixed to the first fixing rod 7, and the detector body 1 is placed into the sea water.

[0052] Furthermore, start the motion motor 8 to rotate, push the sea water through the propeller 9, drive the detector body 1 to move, control the direction motor 10 to rotate to drive the motion motor 8 and the propeller 9 to rotate, which can change the motion direction of the detector body 1. At the same time, control the release motor 37 to rotate continuously to release the limiting rope 4. When the detector body 1 reaches the specified position, the release motor 37 stops rotating, and the released length of the limiting rope 4 is fixed. By controlling the propeller 9 to push the detector body 1 to move away from the fixing cylinder 3 and the first fixing rod 7, the fixing cylinder 3 and the first fixing rod 7 exert a reaction force on the detector body 1 through the limiting rope 4, and the propeller 9 exerts a thrust on the detector body 1 by pushing the sea water. The three forces achieve balance to stabilize the position of the detector body 1 and reduce the impact of sea waves on the equipment.

[0053] Meanwhile, by controlling the rotation of the moving motor 16, the detector body 1 can move within an elliptical range centered on the positions of the fixed cylinder 3 and the first fixed rod 7. When it is necessary for the detector body 1 to move to a farther position, continue to control the release roller 38 to release the restraining rope 4, and increase the length of the restraining rope 4 released from the release roller 38.

[0054] What needs to be further explained is that when it is necessary to detect at a position for a long time, control the air pump 19 to inhale air through the air inlet 20, and fill high-pressure air into the interior of the fifth sliding cylinder 23 through the connecting pipe 25. The fifth sliding cylinder 23 continuously slides downward, and the distance between the fifth sliding cylinder 23 and the first sliding cylinder 21 continuously increases, so that the anchor 24 is inserted into the bottom of the water, fixing the position of the detector body 1, achieving the effect of fixing the position of the detector body 1 for a long time. Similarly, by controlling the air pump 19 to exhaust air, the anchor 24 can be retracted.

[0055] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 8 In a preferred embodiment, the buoyancy mechanism includes mounting rods 33 rotatably connected to the bottoms of both sides of the detector body 1. A rotating rod 30 is rotatably connected to a position on the bottom of the detector body 1 close to the mounting rod 33. One end of the rotating rod 30 is fixedly connected to a piston 31, and one end of the piston 31 is slidably connected to a rotating cylinder 32, and the rotating cylinder 32 is rotatably connected to the mounting rod 33.

[0056] One end of the mounting rod 33 is fixedly connected to a buoyancy cylinder 2. The interior of the buoyancy cylinder 2 is hollow and filled with air. An air guide pipe 34 is inserted into the outer wall of the rotating cylinder 32, and one end of the air guide pipe 34 penetrates through the buoyancy cylinder 2 and extends out from the bottom of the buoyancy cylinder 2.

[0057] In this embodiment, in the case of the undulation of the sea waves, the buoyancy cylinder 2 can increase the buoyancy of the detector body 1. During the undulation of the sea waves, the sea waves will drive the buoyancy cylinder 2 to rise and fall. The rise and fall of the buoyancy cylinder 2 drives the mounting rod 33 to rotate, thereby driving the piston 31 to slide inside the rotating cylinder 32, thus squeezing the air between the rotating cylinder 32 and the piston 31, and discharging the air into the sea water or inhaling sea water through the air guide pipe 34. The damping force in this process plays a role in buffering the shaking of the detector body 1 caused by the sea waves. At the same time, the bubbles discharged through the air guide pipe 34 have a certain effect of driving away fish to a certain extent, reducing the potential impact of fish on the operation of the equipment.

[0058] The working process of this application is divided into the following states:

[0059] When it is necessary to detect at various positions of the shoal, the fixed cylinder 3 is fixed on the beach beside the shoal, and the first fixed rod 7 is also inserted into the beach at a certain distance from the fixed cylinder 3. One end of the limiting rope 4 passes through the middle of the auxiliary wheel 26 and the main wheel 28. One end of the limiting rope 4 is wound around the release roller 38, and the other end of the limiting rope 4 is fixed on the first fixed rod 7. The detector body 1 is placed into the sea water, the movement motor 8 is started to rotate, the sea water is pushed by the propeller 9 to drive the detector body 1 to move. The direction motor 10 is controlled to rotate to drive the movement motor 8 and the propeller 9 to rotate, so that the movement direction of the detector body 1 can be changed. At the same time, the release motor 37 is controlled to rotate to continuously release the limiting rope 4. When the detector body 1 reaches the designated position, the release motor 37 stops rotating, and the released length of the limiting rope 4 is fixed. By controlling the propeller 9 to push the detector body 1 to move away from the fixed cylinder 3 and the first fixed rod 7, the fixed cylinder 3 and the first fixed rod 7 exert a reaction force on the detector body 1 through the limiting rope 4, and the propeller 9 exerts a thrust on the detector body 1 by pushing the sea water. The three forces achieve balance to stabilize the position of the detector body 1, reducing the impact of the sea waves on the equipment. At the same time, by controlling the movement motor 16 to rotate, the detector body 1 can move within an elliptical range with the positions of the fixed cylinder 3 and the first fixed rod 7 as the center. When it is necessary for the detector body 1 to move to a farther position, the release roller 38 is continuously controlled to release the limiting rope 4 to increase the length of the limiting rope 4 released from the release roller 38. In this state, mobile detection can be carried out, facilitating the acquisition of information such as underwater terrain, siltation, and cross-section;

[0060] When it is necessary to detect at one position for a long time, the air pump 19 is controlled to inhale air through the air inlet 20, and high-pressure air is filled into the interior of the fifth sliding cylinder 23 through the connecting pipe 25. The fifth sliding cylinder 23 continuously slides downward, and the distance between the fifth sliding cylinder 23 and the first sliding cylinder 21 is continuously extended, so that the anchor nail 24 is inserted into the bottom of the water to fix the position of the detector body 1, achieving the effect of fixing the position of the detector body 1 for a long time. In this state, the accuracy of environmental factor monitoring, such as wind speed, water flow, etc., can be guaranteed;

[0061] In the case of the undulating sea waves, the buoyancy cylinder 2 can increase the buoyancy of the detector body 1. During the undulation of the sea waves, the sea waves will drive the buoyancy cylinder 2 to rise and fall. The rise and fall of the buoyancy cylinder 2 drives the mounting rod 33 to rotate, thereby driving the piston 31 to slide inside the rotating cylinder 32, thereby squeezing the air between the rotating cylinder 32 and the piston 31, and discharging the air into the sea water or inhaling the sea water through the air guide pipe 34, achieving the effect of buffering the shaking of the sea waves on the detector body 1. At the same time, the bubbles discharged through the air guide pipe 34 can drive away fish, reducing the impact of fish on the detection of the beach formation.

[0062] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
