Description

Technical Field

[0001] The present invention relates to the technical field of remote sensing devices, and more particularly to a remote sensing device for hydrological surveys. Background Art

[0002] Hydrological survey is the study of hydrological characteristics and water resources management through systematic observation, testing and data collection. Therefore, hydrological surveys need to be carried out with the help of dedicated remote sensing devices. Remote sensing devices mainly include sensors and remote sensing satellites or sensors installed in artificial drones for use. Through the cooperation of sensors, electromagnetic radiation from water bodies and surrounding environments can be collected. After processing, this information is converted into recognizable data or images. By analyzing and displaying the distribution of water bodies and reflecting the spatiotemporal changes of hydrological phenomena, the hydrological survey can be completed. Common sensor types include cameras, scanners, radars, etc. In summary, the inventors have discovered that existing remote sensing devices have the following main defects: since the sensors of current remote sensing devices are usually set to be exposed at the entire lower end of the drone, they will be in continuous contact with the outside air. At the same time, when the drone is falling and idle, the bottom sensor will be in direct contact with the ground or table. Therefore, the surface of the sensor will be scratched by the mirror surface caused by direct contact with the outside world, forming a surface phenomenon that cannot protect the sensor. Therefore, the sensor surface will continue to wear further, which will reduce the accuracy of the sensor's subsequent operations. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a remote sensing device for hydrological survey, whose structure includes: a flying rotator, a solar panel, a data host, a balance board, a camera, and a sensor. The flying rotator is installed at the surface center of the solar panel and the solar panel is positioned on the top of the data host. The data host is also connected to a balance board on the left and right sides and a camera is set at the front end. A sensor is also fixed at the lower end of the data host.

[0004] As a further improvement of the present invention, the sensor is also provided with a power-on module, which is embedded in the center of the connecting piece and electrically connected to the sensing body at the lower end. The support column is installed through the lower layers on the left and right sides of the connecting piece. An anti-sliding block is also fixed to the lower end of the support column, and a partition structure is also connected to the side of the anti-sliding block.

[0005] As a further improvement of the present invention, the partition structure is provided with an assembly block, which is welded to the left and right sides of the frame and a through cavity is opened inside the frame. The restraining rod is fixed in parallel through the through cavity, and an adjustment block is connected to the restraining rod to position and control the contact protection body.

[0006] As a further improvement of the present invention, the power module and the sensor body are vertically installed on the lower end of the data host through the sensor connector, and then the support rods on the left and right sides of the connector are combined with the anti-sliding block to contact the ground or the table parallelly, so that the bottom of the sensor body maintains a distance from the ground or the table, and then the anti-sliding block positions the frame of the partition structure, so that the restraining rod in the frame allows the adjustment block to drive the contact protection body to slide, and the contact protection body slides parallel to the bottom layer of the sensor body and overlaps with it.

[0007] As a further improvement of the present invention, the flying rotating body is perpendicular to the solar panel and the solar panel covers the top of the data host. The data host carries a balance board on both sides and uses a front-end camera to observe the flight area. The sensor is located on the lower end surface of the data host and is parallel to it.

[0008] As a further improvement of the present invention, the power module and the center of the connector intersect with each other and are inserted into the top area of the sensor body for electrical connection. The connector is in the shape of a rectangular parallelepiped and has a support column and an anti-sliding block on the lower layers on the left and right sides. The anti-sliding block is then used to determine the position of the partition structure.

[0009] As a further improvement of the present invention, there are two assembly blocks on the edge of the frame and two restraining rods are included in the through cavity of the frame to provide a parallel sliding area for the adjustment block. When the adjustment block slides on the restraining rod, it can drive the contact protection body to slide together.

[0010] As a further improvement of the present invention, the adjustment block is also provided with a solid frame, a sliding frame is provided inside the solid frame, a sliding groove is opened in the sliding frame, and pulley groups are also provided on the left and right sides of the sliding groove. The pulley group is brought into contact with the surface of the restraining rod through the sliding groove, and a slot is also opened in the center of the upper end of the solid frame, and a fixed plug is also provided in the center of the slot.

[0011] As a further improvement of the present invention, the cross-sectional area of the solid frame is larger than the area of the restraining rod, and the restraining rod is allowed to pass through the square slide groove. Two sets of pulley groups are also provided on the left and right sides of the slide groove, and the slot is opened in a vertical direction to allow the fixed plug to pass through vertically.

[0012] As a further improvement of the present invention, the pulley group is also provided with a magnetic block, which is welded to the surface center of the connecting block and an anti-deflection rod is provided at the other end of the connecting block. A locking bolt is also connected to one end of the anti-deflection rod to pass through the center of the wheel and limit the position.

[0013] As a further improvement of the present invention, the magnetic block and the connecting block are perpendicular to each other and the other end of the connecting block is connected to three anti-deflection rods and three locking bolts to position the three wheels and the locking bolts do not need to lock the center of the wheel, but only need to be connected to the anti-deflection rod to leave a rotation gap between the center of the wheel and one end of the anti-deflection rod.

[0014] As a further improvement of the present invention, the contact protection body is also provided with an adapter block, which is welded to the left and right sides of the parallel plate and has a groove in the parallel plate to allow the overlapping plates to be placed in parallel. The sponge block is vertically embedded through the groove so that its bottom overlaps with the surface of the overlapping plate.

[0015] As a further improvement of the present invention, the adapter blocks are provided with two pieces at the edge of the parallel plate and are fixedly connected with the side of the adjustment block. The grooves in the parallel plates are opened in a vertical direction to allow the overlapping plates to be placed in parallel. The sponge block is in the shape of a rectangular parallelepiped and is embedded in the groove in a vertical direction.

[0016] As a further improvement of the present invention, a solid block is newly provided at the edge position of the groove where the sponge block is embedded. The solid block is welded to the outer center of the adsorbent body and a limiting groove is opened at the bottom part of the adsorbent body to allow the center block to be inserted. The center block is welded to the lower center of the edge block and the edge block is vertically installed in the adsorbent body through the center block to overlap with it.

[0017] As a further improvement of the present invention, the solid block is in a square shape and the connected adsorption body is in an "L" shape, the limiting groove and the shape of the center block are consistent with each other, and the edge block is a rectangular solid metal shape.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is based on a connector mounted on the sensor. The support columns and anti-sliding blocks on the left and right sides of the lower end surface of the connector can replace the original lower layer of the sensor body in direct contact with the ground or table, thereby reducing the generation of friction and improving the vertical positioning stability of the origin after the remote sensing device is lowered. Furthermore, the partition structure for positioning the anti-sliding block can pass through the through cavity of the frame without affecting the effect of the sensor body on collecting electromagnetic radiation from water and the surrounding environment. Then, the two built-in restraining rods are used to allow the adjustment block to manually drive the displacement of the contact protection body, so that after the remote sensing device is lowered, the movable contact protection body overlaps and covers the bottom of the sensor body, thereby protecting the bottom of the sensor body.

[0019] 2. The present invention is further improved by the adjustment block. The sliding frame and the sliding groove inside the solid frame can stably slide parallel to the check rod. During the process, the pulley group is used to improve the smoothness of the sliding. At the same time, the pulley group can be positioned by the anti-deflection rod during use to prevent mutual obstruction during rotation. After the position adjustment is completed, the slot can be used to allow the fixed plug to penetrate the surface of the check rod to achieve a limiting effect, thereby preventing the remote sensing device from being affected by the airflow during the investigation, causing the contact protection body to automatically move, thereby affecting the stability of the sensing body in receiving electromagnetic wave radiation from the water body and the surrounding environment.

[0020] 3. After the contact protection body of the present invention is further improved, the parallel plate can be connected with the side of the anti-sliding block through the adapter block, so that the parallel plate can use the groove and the internal overlapping plate to allow the sponge block to be vertically embedded, ensuring that the sponge block can cover the bottom of the sensing body in a stable vertical position. At the same time, the sponge block can determine the position of the edge block through the adsorbent body set on the edge, and then use the shape of the edge block to improve the vertical connection accuracy of the sponge block and the groove. The adsorbent body can then be used to improve the connection stability with the edge block and the solid block can be combined to complete the connection firmness with the metal block carried at the lower end of the sponge block, thereby improving the coordination and stability effect between the components.

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings: Example

The flying rotator 1 is installed at the center of the surface of the solar panel 2, and the solar panel 2 is positioned on the top of the data host 3. The data host 3 is also connected to the left and right sides with a balance board 4 and a camera 5 is set at the front end. A sensor 6 is also fixed at the lower end of the data host 3.

[0031] Among them, the sensor 6 is also provided with a power-on module 61, which is embedded in the center of the connecting piece 62 and electrically connected to the sensor body 63 at the lower end. The support column 64 is installed through the lower layer on the left and right sides of the connecting piece 62. An anti-sliding block 65 is also fixed at the lower end of the support column 64, and a partition structure 66 is also connected to the side of the anti-sliding block 65.

[0032] Among them, the partition structure 66 is provided with an assembly block 661, and the assembly block 661 is welded to the left and right sides of the frame 662, and a through cavity 663 is opened inside the frame 662. The restraining rod 664 is fixed in parallel through the through cavity 663, and an adjustment block 665 is connected to the restraining rod 664 to position and control the contact protection body 666.

[0033] Among them, the power module 61 and the sensor body 63 are vertically installed on the lower end of the data host 3 through the connecting piece 62 of the sensor 6, and then the support rods 64 on the left and right sides of the connecting piece 62 are combined with the anti-sliding block 65 to contact the ground or the table in parallel, so that the bottom of the sensor body 63 maintains a distance from the ground or the table, and then the anti-sliding block 65 positions the frame 662 of the partition structure 66, so that the restraining rod 664 in the frame 662 allows the adjustment block 665 to drive the contact protection body 666 to slide, and the contact protection body 666 slides parallel to the bottom layer of the sensor body 63 and overlaps with it.

[0034] Among them, the flying rotor 1 and the solar panel 2 are perpendicular to each other and the solar panel 2 covers the top of the data host 3. The data host 3 carries a balance board 4 on both sides and uses the front-end camera 5 to observe the flight area. The sensor 6 is located on the lower end surface of the data host 3 and is parallel to it.

[0035] Among them, the power module 61 and the connecting piece 62 intersect with each other at the center and are inserted into the top area of the sensor body 63 for electrical connection. The connecting piece 62 is a rectangular parallelepiped and carries a support column 64 and an anti-sliding block 65 on the lower layers on the left and right sides. The anti-sliding block 65 is then used to determine the position of the partition structure 66.

[0036] Among them, the assembly block 661 is provided with two blocks at the edge of the frame 662 and the through cavity 663 of the frame 662 contains two restraining rods 664 to provide a parallel sliding area for the adjustment block 665. When the adjustment block 665 slides on the restraining rod 664, it can drive the contact protection body 666 to slide together.

[0037] Among them, the adjustment block 665 is also provided with a solid frame 6651, and a sliding frame 6652 is provided inside the solid frame 6651. A sliding groove 6653 is opened in the sliding frame 6652, and pulley groups 6654 are also provided on the left and right sides of the sliding groove 6653. The pulley group 6654 is allowed to contact the surface of the restraining rod 664 through the sliding groove 6653. A slot 6655 is also opened in the center of the upper end of the solid frame 6651, and a fixed plug 6656 is also provided in the center of the slot 6655.

[0038] Among them, the cross-sectional area of the solid frame 6651 is larger than the area of the restraining rod 664, and the restraining rod 664 is allowed to pass through the square sliding groove 6653. Two sets of pulley groups 6654 are also provided on the left and right sides of the sliding groove 6653, and the slot 6655 is opened in a vertical direction to allow the fixed plug 6656 to pass through vertically.

[0039] Among them, the pulley group 6654 is also provided with a magnetic block 6541, which is welded to the surface center of the connecting block 6542 and an anti-deflection rod 6543 is provided at the other end of the connecting block 6542. A locking bolt 6544 is also connected to one end of the anti-deflection rod 6543 to pass through the center of the rotating wheel 6545 and limit its position.

[0040] Among them, the magnetic block 6541 and the connecting block 6542 are perpendicular to each other, and the other end of the connecting block 6542 is connected to three anti-deflection rods 6543 and three locking bolts 6544 to position the three rotating wheels 6545. The locking bolts 6544 do not need to lock the center of the rotating wheel 6545, and only need to be connected to the anti-deflection rod 6543 to leave a rotation gap between the center of the rotating wheel 6545 and one end of the anti-deflection rod 6543.

[0041] Specific functions and operation procedures of this embodiment: In the present invention, the data host 3 of the remote sensing device for hydrological survey can receive sunlight radiation through the solar panel 2 on the top and convert it into electrical energy, so that it can prevent power outages during operation. At the same time, the data host 3 can be quickly rotated through the flying rotator 1 through remote control to achieve a take-off effect. During the flight, stability can be maintained by the balance boards 4 on the left and right sides. At the same time, the front camera 5 can observe the flight path, so that the bottom sensor 6 can accurately reach the relevant water area. At the same time, the sensor 6 can collect electromagnetic wave radiation from the water body and the surrounding environment. After processing, this information is converted into recognizable data or images, which can be displayed by analyzing the distribution of water bodies and reflecting the spatiotemporal changes of hydrological phenomena, so that it can be completed. The hydrological survey operation is completed, so that after the hydrological survey operation is completed, the remote sensing device returns to its original position, so that the top connecting piece 62 of the sensing body 63 of the sensor 6 can complete the interlaced electrical connection with the data host 3 through the power module 61, and then the support columns 64 and anti-sliding blocks 65 arranged on the left and right sides of the lower end surface of the connecting piece 62 can directly contact the ground or the desktop when the data host 3 falls, ensuring that the bottom layer of the sensing body 63 maintains a distance from the ground or the desktop, preventing the sensing body 63 from directly contacting the ground and receiving the weight of the data host 3 and other components, which is very easy to cause damage and large-scale scratches on the bottom layer. Therefore, it can effectively protect the effect of the sensing body 63 and prevent the accuracy of subsequent hydrological surveys from being reduced after the sensing body 63 is damaged. , so that after it falls, all the weight will be concentrated in the support column 64 and the anti-sliding block 65, thereby improving the stability of the remote sensing device after it falls, and then the partition structure 66 carried on the side of the anti-sliding block 65 can be connected with the anti-sliding block 65 through the assembly block 661 of the frame 662, so that the through cavity 663 of the frame 662 can allow the sensor body 63 to communicate with the water below normally, preventing the occurrence of obstruction. Subsequently, the two built-in check rods 664 and the carried adjustment block 665 can manually adjust the position of the contact protection body 666, so that after it falls, the adjustment block 665 is manually adjusted to translate on the check rod 664 to drive the contact protection body 666 to move, so that the contact protection body 666 moves to the bottom layer of the sensor body 63 to cover it, so that It can protect the sensor body 63 when it is idle. Then the solid frame 6651 of the adjustment block 665 can slide parallel to the check rod 664 through the inner sliding frame 6652 and the slide groove 6653. During the process, the left and right pulley sets 6654 can be used to achieve an auxiliary effect, which improves the smoothness of translation and avoids the jamming and unsmooth movement caused by simple plane friction. When it moves to the appropriate position, the fixed plug 6656 can be vertically dropped into the check rod 664 through the top slot 6655 to complete the positioning, preventing the automatic displacement of the adjustment block 665 and the contact protection body 666 caused by the airflow during flight due to the lack of restraint force, thereby ensuring the operational stability of the sensor body 63.Finally, the three rotating wheels 6545 of the pulley assembly 6654 can be installed on one end of the anti-deflection rod 6543 through the locking bolt 6544. The locking bolt 6544 does not need to directly lock the rotating wheel 6545, but only needs to locate its center point to ensure that the rotating wheel 6545 can rotate stably. Then, the three anti-deflection rods 6543 determine the positions of the three rotating wheels 6545 to prevent the displacement caused by resistance when the rotating wheels 6545 rotate, thereby ensuring the stability of the rotating wheels 6545 during rotation. Then, the anti-deflection rod 6543 will be welded to one end of the connecting block 6542, so that it can be stably installed on the inner area of the sliding frame 6652 through the magnetic block 6541 at the other end of the connecting block 6542, so that the components can be used normally. Example

[0042] Figures 6 and 7 As shown: The present invention provides a remote sensing device for hydrological investigation. Its structure includes that the contact protection body 666 is also provided with an adapter block 6661, and the adapter block 6661 is welded to the left and right sides of the parallel plate 6662, and a groove 6663 is opened in the parallel plate 6662 to allow the overlapping plate 6664 to be placed in parallel, and the sponge block 6665 is vertically embedded through the groove 6663 so that its bottom overlaps with the surface of the overlapping plate 6664.

[0043] Among them, the adapter block 6661 is provided with two pieces at the edge of the parallel plate 6662 and is fixedly connected with the side of the adjustment block 665. The groove 6663 in the parallel plate 6662 is opened in a vertical direction to allow the overlapping plate 6664 to be placed in parallel. The sponge block 6665 is in the shape of a rectangular parallelepiped and is embedded in the groove 6663 in a vertical direction.

[0044] Among them, a solid block 6666 is newly provided at the edge position of the sponge block 6665 embedded in the groove 6663, and the solid block 6666 is welded to the outer center of the adsorption body 6667 and a limiting groove 6668 is opened at the bottom part of the adsorption body 6667 to allow the center block 6669 to be inserted, and the center block 6669 is welded to the lower end center of the edge block 6610 and the edge block 6610 is vertically installed in the adsorption body 6667 through the center block 6669 to overlap with it.

[0045] Among them, the solid block 6666 is square in shape and the connected adsorption body 6667 is "L" shaped, the limiting groove 6668 and the center block 6669 are consistent in shape, and the edge block 6610 is a solid rectangular metal shape.

[0046] Specific functions and operation procedures of this embodiment: In the present invention, the parallel plate 6662 of the contact protection body 666 can be fixedly connected with the side of the adjustment block 665 through the side adapter block 6661, and then the groove 6663 of the parallel plate 6662 can allow the overlapping plate 6664 to be embedded in parallel so that it covers the bottom of the parallel plate 6662. Then the sponge block 6665 inserts and positions the newly added solid block 6666 and the adsorbent 6667 on the edge through the metal block superimposed on the bottom. To this end, the adsorbent 6667 allows the center block 6669 of the edge block 6610 to be vertically inserted according to the "L" shape and the bottom limiting groove 6668, ensuring that the edge block 6610 can be vertically inserted and limited with the edge of the groove 6663 of the parallel plate 6662 in the vertical direction. , and then the adsorptive body 6667 can ensure the connection between the solid block 6666 and the bottom edge of the sponge block 6665 according to the magnetic effect. Then, after the sponge block 6665 is vertically inserted into the groove 6663 through the edge block 6610, its bottom will overlap with the overlapping plate 6664, so that it can achieve the effect of easy disassembly and assembly. Then, through the cooperation of the sponge block 6665, the bottom of the sensor body 63 can be covered. Therefore, according to the flexible effect of the sponge block 6665, it can protect the characteristics of the sensor body 63 and absorb the water molecules remaining on the sensor body 63 (because when conducting hydrological surveys, the sensor body 63 is exposed to the outside, and then it is very easy to produce water vapor remaining in the lower surface area of itself under the influence of humid air).
