Abstract
Description
Technical Field
[0001] This invention relates to the field of geological surveying technology, and in particular to a shoreline topographic observation device that can automatically adjust the measurement position. Background Technology
[0002] Due to environmental changes, some inland lakes will gradually turn into saltwater lakes. Such lakes have poor ecological environments and therefore need ecological restoration. In order to facilitate the restoration of lake ecology, an underground monitoring device for the lake shore is needed.
[0003] Existing lake shore topographic observation equipment suffers from several drawbacks. The measurement range is fixed and cannot be automatically adjusted, hindering its use. Furthermore, the equipment's proximity to the lake means that water mist can be blown onto the instrument, and the evaporation of this mist leaves behind salt particles that corrode the instrument and scratch the lens, further complicating measurements. Moreover, the existing equipment's fixation is inadequate; the pins used for fixing the device are corroded by moisture and metal ions from the lake shore soil, causing the device's position to shift over time and leading to measurement errors. Additionally, once the fixing rods are corroded and weakened, wind can easily topple the device, causing damage. Summary of the Invention

A connecting sleeve is slidably connected to the rotating shaft, and the connecting sleeve is slidably sleeved on the connecting rod.
[0006] Preferably, the power structure includes a power shaft rotatably connected to the support housing, with power fan blades fixedly connected to both ends of the power shaft through the inner walls of the corresponding support housings, a fixed worm gear fixedly sleeved on the power shaft, the fixed shaft passing through the mounting frame and extending into the interior of the support housing, and a fixed worm wheel meshing with the fixed worm gear fixedly sleeved on the fixed shaft.
[0007] Preferably, an auxiliary fixing structure is installed inside the support housing. The auxiliary fixing structure includes a fixed shell fixedly connected to a fixed base. A connecting pipe communicating with the interior of the fixed shell is fixedly connected to the bottom end of the fixed shell. A pressure piston is slidably installed between the inner walls of the connecting pipe. An auxiliary rod is fixedly connected to the pressure piston. An I-shaped piston is slidably connected between the inner walls of the fixed shell. A return spring is fixedly connected between the I-shaped piston and the inner wall of the fixed shell. A fixing pipe is fixedly connected to the fixed shell. An installation shaft is rotatably connected to the inner wall of the support housing. The installation shaft passes through the inner wall of the fixed shell and extends into the interior of the fixed shell. A fixed fan blade is fixedly installed on the installation shaft. The installation shaft and the power shaft are connected by a first belt drive assembly.
[0008] Preferably, the fixed base has a corresponding insertion hole for the auxiliary insertion rod, a sealing gasket is fixedly installed at the connection between the mounting shaft and the fixed shell, pressurized oil is filled between the connecting pipe and the fixed pipe, and compressed gas is filled in the two connected parts of the fixed pipe.
[0009] Preferably, the cleaning structure includes a protective shell rotatably connected to the mounting bracket. The protective shell encloses the adjustment structure and measuring instrument on its inner wall. A rotating rod is fixedly connected to the top of the protective shell. A baffle plate is rotatably connected to the rotating rod. A stabilizing rod and a reciprocating screw are rotatably connected between the baffle plate and the mounting plate. A cleaning plate is mechanically fitted onto the reciprocating screw, and the cleaning plate is sleeved on the outside of the stabilizing rod. The rotating rod and the reciprocating screw are connected by a second belt drive assembly. A fixed gear ring that meshes with the adjusting gear is fixedly connected to the inner wall of the protective shell.
[0010] Preferably, the protective shell is made of transparent material and has a matte coating. A sliding block is fixedly connected to the bottom of the protective shell. An annular groove corresponding to the sliding block is opened on the mounting plate.

At the same time, a cleaning plate that moves up and down is installed. With the rotation of the protective shell, the protective shell can be cleaned without affecting the measuring instrument's measurement, which is beneficial for the measuring instrument to perform measurements.

Detailed Implementation
[0016] See Figures 1-8 A shoreline topographic observation device with automatically adjustable measurement position, comprising: Mounting plate 1, mounting plate 1 has a support shell 5 fixedly mounted on it, mounting shell 5 has a fixed base 15 fixedly mounted on it, mounting plate 1 has a mounting frame 2 fixedly mounted on it, mounting frame 2 has a rotating shaft 3 rotatably connected to it, and rotating shaft 3 has a measuring instrument 4 fixedly connected to it. Mounting plate 1 has a cleaning structure 9 mounted on it. The measuring instrument 4 is an existing device, which is a laser measuring instrument, used to automatically measure the topography of the lake shore. like Figure 5 and Figure 6 As shown, the adjustment structure 6 includes an adjustment shaft 61 and a fixed shaft 10 rotatably connected to the mounting plate 1. An adjustment gear 63 is fixedly sleeved on the adjustment shaft 61, and a fixed gear 62 that meshes with the adjustment gear 63 is fixedly sleeved on the fixed shaft 10. A power structure 7 is installed on the fixed shaft 10. The adjustment shaft 61 passes through the mounting frame 2 and is fixedly connected to a fixed disk 65. An adjustment rod 66 is fixedly connected to the fixed disk 65. A connecting rod 67 is rotatably sleeved on the adjustment rod 66. A connecting sleeve rod 68 is slidably connected to the rotating shaft 3, and the connecting sleeve rod 68 is slidably sleeved on the connecting rod 67. When the fixed shaft 10 rotates, the threaded rod 11, which is fixedly connected to the fixed insertion rod 12, cannot rotate. Therefore, under the action of the thread, the threaded rod 11 will move downward with the rotation of the fixed shaft 10, pushing the fixed insertion rod 12 to move downward as well. The fixed insertion rod 12 extends into the soil to further fix the device. At the same time, as the part of the fixed insertion rod 12 in the soil is corroded, the uncorroded part of the fixed insertion rod 12 that was originally located on the fixed seat 15 extends into the soil to prevent its fixing effect on the device from decreasing. like Figure 2 , Figure 3 and Figure 4 As shown, the power structure 7 includes a power shaft 71 rotatably connected to the support housing 5. Both ends of the power shaft 71 penetrate the inner walls of their respective support housings 5 and are fixedly connected to power fan blades 72. The upper end of the power fan blades is arc-shaped, and the lower end is straight. Therefore, when wind blows, the airflow speed at the upper end of the power fan blades 72 is faster than at the lower end. The faster the airflow speed, the lower the pressure. Thus, the air pressure causes the power fan blades to move upwards, causing the power fan blades 72 to rotate. Figure 1 For reference, the power fan blade 72 rotates counterclockwise, a fixed worm gear 73 is fixedly sleeved on the power shaft 71, the fixed shaft 10 passes through the mounting bracket 2 and extends into the interior of the support housing 5, and a fixed worm wheel 74 that meshes with the fixed worm gear 73 is fixedly sleeved on the fixed shaft 10. When the wind blows, the wind will cause the power fan blade 72 to rotate, which will drive the power shaft 71 to rotate as well. This will cause the fixed worm gear 73, which is fixedly sleeved on the power shaft 71, to rotate as well, which will drive the fixed worm wheel 74, which meshes with the fixed worm gear 73, to rotate, and cause the fixed shaft 10 to rotate as well. like Figure 8 As shown, an auxiliary fixing structure 8 is installed inside the support housing 5. The auxiliary fixing structure 8 includes a fixing shell 81 fixedly connected to the fixing base 15. A connecting pipe 87 communicating with the interior of the fixing shell 81 is fixedly connected to the bottom end of the fixing shell 81. A pressure piston 88 is slidably installed between the inner walls of the connecting pipe 87. An auxiliary insertion rod 89 is fixedly connected to the pressure piston 88. An I-shaped piston 82 is slidably connected between the inner walls of the fixing shell 81, and a return spring is fixedly connected between the I-shaped piston 82 and the inner wall of the fixing shell 81. A fixing pipe 83 is fixedly connected to the fixing shell 81. Figure 8 For reference, the fixed tube 83 fixes the inner side of the I-shaped piston 82 to the left side of the I-shaped piston 82. The inner wall of the support housing 5 is rotatably connected to the mounting shaft 84. The mounting shaft 84 passes through the inner wall of the fixed housing 81 and extends into the interior of the fixed housing 81. The fixed fan blade 86 is fixedly mounted on the mounting shaft 84. The mounting shaft 84 and the power shaft 71 are connected by the first belt drive assembly 85. Under the action of the first belt drive assembly 85, the mounting shaft 84 rotates along with the power shaft 71. When the wind increases, the rotational speed of the power shaft 71 increases, and the rotational speed of the mounting shaft 84 also increases. The rotational speed of the fixed fan blades 86, which are fixedly connected to the mounting shaft 84, also increases, drawing air from the inside of the I-beam piston 82 to the left side of the I-beam piston 82. Figure 8 For reference, compressed air pushes the I-shaped piston 82 to the right, thereby pushing the pressurizing piston 88 downward, causing the auxiliary insertion rod 89 to also move downward and insert into the soil to further secure the device and prevent it from being blown away by the wind, which could damage the measuring instrument. After the wind subsides, the spring force of the return spring causes the I-shaped piston 82 to return to its original position, and the compressed air returns to the inside of the I-shaped piston 82. The pressurizing piston 88 moves upward, causing the auxiliary insertion rod 89 to return to the top of the mounting base 15, preventing the auxiliary insertion rod 89 from being corroded. The fixed base 15 has a corresponding insertion hole for the auxiliary insertion rod 89. The auxiliary insertion rod 89 can extend into the soil through the insertion hole and return to the fixed base 15. A sealing gasket is fixedly installed at the connection between the mounting shaft 84 and the fixed housing 81 to prevent compressed gas leakage. Pressurized oil is filled between the connecting pipe 87 and the fixed pipe 83. Compressed gas is filled in the two connected parts of the fixed pipe 83. like Figure 7 As shown, the cleaning structure 9 includes a protective shell 13 rotatably connected to the mounting frame 2. The protective shell 13 encloses the adjustment structure 6 and the measuring instrument 4 on its inner wall. A rotating rod 95 is fixedly connected to the top of the protective shell 13. The rotating rod 95 is installed at the center of the top of the protective shell 13. A baffle plate 14 is rotatably connected to the rotating rod 95. A stabilizing rod 91 and a reciprocating screw 92 are rotatably connected between the baffle plate 14 and the mounting plate 1. A cleaning plate 93 is mechanically fitted on the reciprocating screw 92, and the cleaning plate 93 is sleeved on the outside of the stabilizing rod 91. The cleaning plate 93 and the stabilizing rod 91 are not connected. The stabilizing rod 91 fixes the cleaning plate 93 so that it cannot rotate. Therefore, the cleaning plate 93 will move up and down with the rotation of the reciprocating screw 92. The rotating rod 95 and the reciprocating screw 92 are connected by a second belt drive assembly 94. A fixed gear ring 64 that meshes with the adjusting gear 63 is fixedly connected to the inner wall of the protective shell 13. When the adjusting gear 63 rotates, the fixed gear ring 64 meshing with it rotates accordingly, driving the protective shell 13 to rotate. The rotating rod 95 fixedly installed on the protective shell 13 rotates accordingly. Under the action of the second belt drive assembly 94, the reciprocating screw 92 rotates, causing the cleaning plate 93 that is mechanically engaged with it to move up and down to clean the protective shell 13. At the same time, the rotation of the protective shell 13 allows the cleaning plate 93 to clean the entire protective shell 13, so as to facilitate the measurement of the measuring instrument 4. Moreover, the cleaning plate 93 only moves in the vertical direction and will not block the lens of the measuring instrument 4. The protective shell 13 is made of transparent material, which allows the measuring instrument to perform measurements. The protective shell 13 is coated with a matte coating, which reduces the light intensity at the measuring instrument 4 and prevents excessive light intensity from affecting the operation of the measuring instrument 4. A sliding block is fixedly connected to the bottom of the protective shell 13. The mounting plate 1 has an annular groove corresponding to the sliding block. A cleaning sponge is fixedly connected to the cleaning plate 93 by Velcro. The cleaning sponge is attached to the protective shell 13, which allows for easy replacement of the cleaning sponge. like Figure 1 , Figure 2 As shown, a mounting rod is fixedly installed at the bottom of the fixed base 15, and a threaded rod 11 is threadedly connected to the inner wall of the fixed shaft 10. A fixed rod 12 is fixedly connected to the threaded rod 11. The fixed rod 12 passes through the fixed base 15 and extends to the bottom of the fixed base 15. The fixed rod 12 is slidably connected to the fixed base 15. When the fixed shaft 10 rotates, the threaded rod 11 fixedly connected to the fixed rod 12 cannot rotate. Therefore, under the action of the thread, the threaded rod 11 will move downward with the rotation of the fixed shaft 10, pushing the fixed rod 12 to move downward as well. The fixed rod 12 extends into the soil to further fix the device. At the same time, as the part of the fixed rod 12 in the soil is corroded, the uncorroded fixed rod that was originally located on the fixed base 15 extends into the soil to avoid a decrease in its fixing effect on the device. A lighting lamp is fixedly installed on the mounting plate 1. The lighting lamp serves as a supplementary light source to prevent the measuring instrument 4 from malfunctioning when there is thick fog on the lake shore. The lighting lamp is equipped with a battery to power it. The mounting plate 1, the support housing 5, and the fixing base 15 are all made of corrosion-resistant materials to prevent the mounting plate and other components exposed to the air from being corroded.
[0017] In this invention, the device is fixed in place by the mounting base 15. The measuring instrument 4 measures the topographic features of the lake shore. When the wind blows, the wind causes the power fan blade 72 to rotate, which in turn drives the power shaft 71 to rotate. This causes the fixed worm gear 73, which is fixedly sleeved on the power shaft 71, to rotate. This drives the fixed worm wheel 74, which meshes with the fixed worm gear 73, to rotate, causing the fixed shaft 10 to rotate as well. When the fixed shaft 10 rotates, it drives the fixed gear 62, which is fixedly sleeved on the fixed shaft 10, to rotate. This causes the adjusting gear 63, which meshes with the fixed gear 62, to rotate, causing the adjusting shaft 61 to rotate. This causes the rotating disk 65, which is fixedly mounted on the adjusting shaft 61, to rotate. The adjusting rod 66, which is mounted on the rotating disk 65, moves in a circular motion, causing the adjusting rod 66 and the connecting rod 67 to move together. This causes the rotating shaft 3 to rotate back and forth, and the measuring instrument 4 to rotate back and forth as well. This allows for automatic adjustment of the measuring position of the measuring instrument 4, expanding the measurement range of the device. Moreover, during the rotation of the measuring instrument 4, there are overlapping measurement positions, thus achieving the effect of measuring at different angles. This allows for calibration of the measurement data, making the data more accurate. When the adjusting gear 63 rotates, the fixed gear ring 64 meshing with it rotates accordingly, driving the protective shell 13 to rotate. The rotating rod 95 fixedly installed on the protective shell 13 rotates accordingly. Under the action of the second belt drive assembly 94, the reciprocating screw 92 rotates, causing the cleaning plate 93 that is mechanically engaged with it to move up and down to clean the protective shell 13. At the same time, the rotation of the protective shell 13 allows the cleaning plate 93 to clean the entire protective shell 13, so as to facilitate the measurement of the measuring instrument 4. Moreover, the cleaning plate 93 only moves in the vertical direction and will not block the lens of the measuring instrument 4. At the same time, when the fixed shaft 10 rotates, the threaded rod 11, which is fixedly connected to the fixed insertion rod 12, cannot rotate. Therefore, under the action of the thread, the threaded rod 11 will move downward with the rotation of the fixed shaft 10, pushing the fixed insertion rod 12 to move downward as well. The fixed insertion rod 12 extends into the soil to further fix the device. At the same time, as the part of the fixed insertion rod 12 in the soil is corroded, the uncorroded part of the fixed insertion rod 12 that was originally located on the fixed seat 15 extends into the soil to avoid a decrease in its fixing effect on the device. Under the action of the first belt drive assembly 85, the mounting shaft 84 rotates along with the power shaft 71. When the wind increases, the rotational speed of the power shaft 71 increases, and the rotational speed of the mounting shaft 84 also increases. The rotational speed of the fixed fan blades 86, which are fixedly connected to the mounting shaft 84, also increases, drawing air from the inside of the I-beam piston 82 to the left side of the I-beam piston 82. Figure 8 For reference, compressed air pushes the I-shaped piston 82 to the right, thereby pushing the pressurizing piston 88 downward, causing the auxiliary insertion rod 89 to also move downward and insert into the soil to further secure the device and prevent it from being blown away by the wind, which could damage the measuring instrument. After the wind subsides, the spring force of the return spring causes the I-shaped piston 82 to return to its original position, and the compressed air returns to the inside of the I-shaped piston 82. The pressurizing piston 88 moves upward, causing the auxiliary insertion rod 89 to return to the top of the mounting base 15, preventing the auxiliary insertion rod 89 from being corroded.
