Technical Field

[0002] Remote sensing monitoring is a technical method for monitoring using remote sensing technology, mainly including ground cover, atmosphere, ocean and near-surface conditions. Remote sensing monitoring technology is a technology that collects electromagnetic wave information of the environment through aviation or satellites to monitor and identify environmental quality conditions of distant environmental targets. It is an advanced environmental information acquisition technology that is "fast" and "complete" in acquiring large-area synchronous and dynamic environmental information, which is unmatched and cannot be completed by other detection methods. Therefore, it is increasingly widely used, such as remote sensing monitoring of atmosphere and water quality, investigation of marine oil pollution accidents, investigation of urban thermal environment and thermal pollution of waters, investigation of urban green space, landscape and environmental background, investigation and monitoring of ecological environment, etc. Existing remote sensing monitoring means include the use of drones for low-altitude remote sensing technology, such as application number: CN202321804249.9, which discloses a remote sensing water quality detection device, which belongs to the field of water quality detection technology, including a body, and wings fixedly installed at the four corners of the top of the body, a solar panel is fixedly installed at the center of the upper end surface of the body through an adjustment component, a water quality analyzer is fixedly installed on the right side of the lower end surface of the body, and a battery for storing electrical energy converted by the solar panel is fixedly installed on the left side of the lower end surface of the body, and the battery is electrically connected to the water quality analyzer, and support plates are fixedly installed on the upper and lower sides of the lower end surface of the body, and a winding shaft is rotatably installed between the support plates on the upper and lower sides, and a signal line is fixedly installed on the side wall of the winding shaft, and a water quality detection head is fixedly installed on the end of the signal line. The utility model can place the water quality detection head into different depths in the river channel through the cooperation of the winding shaft and the signal line, so as to realize the function of accurately detecting the water quality.

[0003] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, the signal line connecting the water quality detection head and the water quality analyzer is wound on a winding shaft, and the signal line is retracted and released by a motor to drive the winding shaft, thereby completing the water quality detection through the low-altitude remote sensing technology of the unmanned aerial vehicle. However, during the retraction and release of the signal line, there is a lack of limiting measures for the signal line, which will be affected by the airflow in the air and the water flow in the water, causing the signal line to drive the water quality detection head to shift relative to the position of the unmanned aerial vehicle, resulting in the actual detection area deviating from the predetermined detection area, which may cause the detection result to lack accuracy.

[0004] How to invent an ocean remote sensing detection device to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

However, during the process of retracting and releasing the signal line, there is a lack of limiting measures for the signal line, which will be affected by the airflow in the air and the water flow in the water, causing the signal line to drive the water quality detection head to deviate from the relative position of the unmanned aerial vehicle, resulting in the actual detection area deviating from the predetermined detection area, which may cause the problem of lack of accuracy in the detection result.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a marine remote sensing detection device, including a drone 1, a marine water quality detection component 2 is arranged at the bottom of the drone 1, the marine water quality detection component 2 includes a shell 201, a water quality analyzer 4 and a retractable mechanism are fixedly installed inside the shell 201, and a detection probe 5 corresponding to the water quality analyzer 4 is also arranged outside the shell 201, the detection probe 5 and the water quality analyzer 4 are connected by a connecting wire 6, one end of the connecting wire 6 extends to the outside of the shell 201 through an extension hole arranged on the inner wall of the bottom of the shell 201, and the retractable mechanism includes a winding shaft 202, the connecting wire 6 is wound on the winding shaft 202, and the two ends of the winding shaft 202 are respectively rotatably installed on the corresponding bracket 203 , two brackets 203 are fixedly connected to the inner wall at the bottom of the shell 201, and a retractable and extendable limit mechanism 3 is fixedly installed on the surface of one side of the shell 201. The retractable and extendable limit mechanism 3 includes a mounting seat 301, and a mounting groove 302 is penetrated on the surface of one side of the mounting seat 301. A linkage rack 303 is arranged in the mounting groove 302, and a limit frame 304 is arranged at the bottom end of the linkage rack 303. The outer wall of one end of the connecting wire 6 close to the detection probe 5 is fixedly connected to the limit frame 304, one end of the winding shaft 202 extends to the outside of the shell 201 through a through hole arranged on the inner wall of one side of the shell 201 and is fixedly sleeved with a linkage gear 207, which is meshed and connected with the linkage rack 303. The retractable and extendable mechanism also includes a driving device.

[0021] See also Figure 3 and Figure 4A limiting hole 305 is formed through the surface of one end of the limiting frame 304 , and the outer wall of one end of the connecting wire 6 is fixedly connected to the inner wall of the limiting hole 305 .

[0022] By fixing one end of the connecting wire 6 in the limiting hole 305, the position of the detection probe 5 can be limited, thereby avoiding the deviation caused by airflow and shaking of the drone 1 during flight, which causes the detection area to deviate and reduce the detection accuracy. In actual use, a clamping mechanism can be set at one end of the limiting frame 304 to clamp and limit one end of the connecting wire 6 so that the connecting wire 6 and the limiting frame 304 can be separated more conveniently.

[0023] Furthermore, the driving device includes a driving motor 206, which is fixedly mounted on the inner wall of the bottom of the housing 201. A driving gear 205 is fixedly sleeved on one end of the output shaft of the driving motor 206. The driving gear 205 is meshed and connected with a driven gear 204 on one side. The driven gear 204 is fixedly sleeved on the other end of the winding shaft 202.

[0024] When the driving motor 206 is started to drive the active gear 205 to rotate, the active gear 205 drives the driven gear 204 meshing on one side to rotate, so that the winding shaft 202 rotates together. The winding shaft 202 can retract and release the connecting wire 6 according to the rotation direction, and adjust the distance of the detection probe 5 relative to the shell 201. While the winding shaft 202 rotates, the linkage gear 207 will also rotate synchronously. The linkage gear 207 drives the linked rack 303 meshing on one side to slide independently relative to the mounting seat 301. Therefore, when the winding shaft 202 releases or reels in the connecting wire 6 and adjusts the position of the detection probe 5, the limit frame 304 will always move up and down with the rotation of the winding shaft 202. Therefore, whether in the process of releasing the detection probe 5 or retracting the detection probe 5, the limit frame 304 can limit the detection probe 5 with proportional displacement, thereby improving the stability during use and preventing the detection probe 5 from being affected by air flow and water flow and causing position deviation.

[0025] Furthermore, the driving motor 206 is located at a side away from the linkage rack 303 .

[0026] Since the mounting seat 301 and the linkage rack 303 are integrally arranged on one side of the housing 201 , the overall center of gravity will be shifted to one side. Arranging the drive motor 206 on the other side of the housing 201 can relatively balance the overall center of gravity.

[0027] Furthermore, sliding bars 306 are provided on both side surfaces of the linkage rack 303 , and sliding grooves 307 corresponding to the sliding bars 306 are provided on both side inner walls of the installation groove 302 , and each sliding bar 306 is slidably connected to the corresponding sliding groove 307 .

[0028] The linkage rack 303 is slidably installed in the mounting groove 302 through the cooperation of the slide bar 306 and the slide groove 307, and can only slide up and down relative to the mounting seat 301 following the rotation of the linkage gear 207, thereby improving stability during use and avoiding shaking during the limiting process.

[0029] See also Figure 2 L-shaped connecting plates 208 are provided at both ends of the top surface of the shell 201, and mounting holes are opened at both ends of the surface of one side of each L-shaped connecting plate 208. A connecting bolt 209 is inserted in each mounting hole, and one end of each connecting bolt 209 is threadedly connected to the corresponding connecting screw hole 210. The four connecting screw holes 210 are respectively opened on both sides of the two end surfaces of the drone 1.

[0030] Through the cooperation between the L-shaped connecting plate 208, the connecting bolt 209 and the connecting screw hole 210, the marine water quality detection component 2 as a whole and the drone 1 can be detachably connected. The two can be easily disassembled and assembled to reduce limitations in use, such as replacing and installing other detection instruments and corresponding sensors under the drone 1 to detect seawater in other directions.

[0031] Working principle: the drone 1 is controlled to fly to a predetermined position on the sea surface, and the driving motor 206 is started to drive the winding shaft 202 to rotate, and the connecting wire 6 is gradually released through the extension hole. The rotation of the winding shaft 202 will drive the linkage gear 207 to rotate. The rotation of the linkage gear 207 drives the linkage rack 303 on one side to independently slide down in the installation groove 302. The limiting hole 305 set on the limiting frame 304 limits the end of the connecting wire 6 close to the detection probe 5, and the limiting process is proportional and synchronous with the wire-releasing process of the winding shaft 202, so as to ensure the stability of the detection probe 5 during the downward displacement process, and will not be offset by the airflow and the water flow after entering the water, resulting in a decrease in the detection accuracy. In the process of retracting the detection probe 5, the linkage rack 303 will also slide upward to limit one end of the connecting wire 6 in the same way as the above-mentioned linkage process, so as to ensure that the connecting wire 6 will not be affected by the airflow and water flow during the process of retracting, causing a large angle to be offset, causing wear between its outer wall and the extension hole, and affecting the overall service life of the connecting wire 6.

[0032] It should be noted that the specific models and specifications of the drone 1, drive motor 206, water quality analyzer 4 and detection probe 5 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and principles of the UAV 1, the drive motor 206, the water quality analyzer 4 and the detection probe 5 are clear to those skilled in the art and will not be described in detail here.

[0034] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
