Description

Technical Field

[0001] This invention belongs to the field of remote sensing detection technology, and specifically relates to a remote sensing detection device for ecological environment. Background Technology

[0002] Remote sensing monitoring is widely used in meteorology, land surveys, oceanography, agriculture, geology, and military fields. In the marine field, pollutants present in surface water or seawater affect and alter the backscattering characteristics of the water surface. Thus, the ability of a sensor to detect changes in the energy spectral signal reflected from the water surface determines the remote sensing applications for measuring water quality parameters. Energy at specific wavelengths can represent the presence and concentration of pollutants in the water. Therefore, the optimal wavelength band for monitoring different water quality parameters depends on the characteristics of the substance being measured and the sensor.

[0003] Light in water is the portion of solar radiation that enters the water body after refraction and scattering. Light in water, reflected light from the water surface, and light scattered from the sky are all received by aerial remote sensing detectors. The detection results are functions of wavelength, altitude, incident angle, and observation angle, with the former containing information about the water. Therefore, by detecting light in water and reflected light from the water surface using high-altitude remote sensing, information such as water color, water flow, and water surface morphology can be obtained. From this, information about the quality and quantity of plankton, turbid water, oil spills, and sewage, as well as information about water surface waves, can be inferred. Therefore, measuring and analyzing the spectrum (including visible and near-infrared light) formed by the absorption and scattering of solar radiation by water bodies through remote sensing systems is the foundation of water environment remote sensing monitoring. Existing water environment remote sensing devices are usually installed directly in the water to receive solar radiation. However, because floating debris easily appears on the surface of the water body being monitored, it can obstruct the water flow. This debris affects the refraction and scattering of sunlight on the water surface and in the water, thus affecting the detection results. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a remote sensing detection device for ecological environment, which can avoid the influence of garbage on the water surface on the reflected light of suspended matter and the bottom of the water when collecting the water reflectance spectrum through the remote sensing instrument body 1, thereby avoiding the impact on the detection effect of water quality and ecological environment. At the same time, it can also collect garbage on the water surface in water with undulating waves, and use the spectral data collected by the two sets of remote sensing instruments to detect the position of suspended matter.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A remote sensing monitoring device for ecological environment includes two sets of remote sensing instrument bodies and a fixing mechanism. The fixing mechanism is slidably connected to a mounting frame. A rectangular frame is fixedly connected to the periphery of the mounting frame. Through holes are provided on the lower sides of all four sides of the rectangular frame. Floating rings are installed on the upper end of the mounting frame and the inner side of the rectangular frame. A mounting cylinder is fixedly connected to the upper end of the mounting frame.

An installation groove matching the pull member is provided inside the L-shaped rod. A sliding rod that is slidably and sealingly connected to the L-shaped rod is fixedly connected to the end of the pull member. A collection basket that abuts against the rectangular frame is installed on the upper end of the sliding rod. An elastic member that is installed on the L-shaped rod is fixedly connected to the lower end of the sliding rod. A collection net that is slidably connected to the collection basket is fixedly connected to the side of the rectangular frame.

[0009] The balancing component includes a connecting ring fixedly connected between two L-shaped rods, and a chain is fixedly installed on the embedded plate and the connecting ring, with an anchor fixedly connected to the middle of the chain.

[0010] The mounting cylinder is equipped with a solar panel, which includes two solar panels and a battery assembly. The upper end of the mounting cylinder is inclined with a second slope, and the two solar panels are respectively mounted on the upper ends of the two second slopes. The battery assembly is installed inside the mounting cylinder.

[0011] The adjustment mechanism includes a threaded rod rotatably connected to the mounting cylinder, the threaded rod being threadedly connected to an empty cylinder, and a mounting plate being fixedly connected to the lower end of the empty cylinder. One set of the remote sensing instrument bodies is mounted on the lower end of the mounting plate, and a limiting rod that slides vertically and vertically connected to the upper end of the mounting plate is fixedly connected to the upper end of the mounting plate.

[0012] A rotating assembly is installed at the lower end of the collection basket. The rotating assembly includes a mounting shaft that is rotatably connected to the collection basket.

[0024] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1:

[0026] like Figure 1-6 As shown, an ecological environment remote sensing detection device of the present invention includes two sets of remote sensing instrument bodies 1 and a fixing mechanism. A mounting frame 11 is slidably connected to the fixing mechanism. A rectangular frame 12 is fixedly connected to the periphery of the mounting frame 11. Through holes 13 are provided on the lower sides of all four sides of the rectangular frame 12. A floating ring 14 is installed on the upper end of the mounting frame 11 and the inner side of the rectangular frame 12. A mounting cylinder 15 is fixedly connected to the upper end of the mounting frame 11. One set of remote sensing instrument bodies 1 is installed on the lower end of the mounting cylinder 15 through an adjustment mechanism, and the other set of remote sensing instrument bodies 1 is installed on the mounting cylinder. On the 15th side, the fixing mechanism is symmetrically fixedly connected with an L-shaped rod 16. The lower end of the mounting cylinder 15 is fixedly connected with a pull member 17 that passes through the L-shaped rod 16. The L-shaped rod 16 has an installation groove that matches the pull member 17. The end of the pull member 17 is fixedly connected with a slide rod 18 that is sealed and slidably connected to the L-shaped rod 16. The upper end of the slide rod 18 is equipped with a collection basket 19 that abuts against the rectangular frame 12. The lower end of the slide rod 18 is fixedly connected with an elastic member 20 that is installed with the L-shaped rod 16. The side of the rectangular frame 12 is fixedly connected with a collection net 21 that is slidably connected to the collection basket 19.

[0027] When in use, the device is fixed to the riverbed by a fixing mechanism, so that the float 14 floats on the water surface and is limited by the fixing mechanism. This prevents the detection device from drifting away under the action of the water flow. In its natural state, the elastic element 20 pushes the slide bar 18 upward, so that the slide bar 18 drives the collection basket 19 to be located on the upper side of the rectangular frame 12. After the entire device is installed, the upper part of the rectangular frame 12 will extend out of the water surface under the action of the float 14. At the same time, the rectangular frame 12 pulls the pulling member 17 and the sliding rod 18 downward, thereby causing the sliding rod 18 to compress the elastic member 20 and make the collection basket 19 enter the water surface. At this time, the distance between the collection basket 19 and the water surface can be adjusted by adjusting the distance between the float 14 and the L-shaped rod 16. Because the mounting frame 11 is slidably connected to the fixing mechanism, and the L-shaped rod 16 is fixedly connected to the fixing mechanism, the distance between the L-shaped rod 16 and the float 14 will change. The position of the collection basket 19 can be adjusted by changing the distance, so that the collection basket 19 is level with the water surface, and the diagonal of the rectangular frame 12 is in the same direction as the water flow, and the two collection baskets 19 are perpendicular to the water flow direction.

[0028] After installation, the two sets of remote sensing instruments 1 are activated. The remote sensing instrument 1 installed on the water surface can detect the direct reflection of sunlight from the water surface, while the remote sensing instrument 1 installed underwater can detect the refraction and reflection of sunlight after it enters the water. The two sets of remote sensing instruments 1 are used to detect and analyze the reflection spectrum characteristics of the water body, thereby determining the ecological environment of the water body. At the same time, the reflection light from the water surface, suspended matter, and bottom collected by the upper remote sensing instrument 1 and the reflection light from the bottom and suspended matter collected by the lower remote sensing instrument 1 are combined to form a complete reflection spectrum of the water body. This avoids differences in the reflection spectrum received by the remote sensing instrument 1 at a single location, which could affect the detection results. The signal receiving position of the lower remote sensing instrument 1 can be adjusted by the adjustment mechanism to determine the distance between the two sets of remote sensing instruments 1. The location of suspended matter in the water body can then be analyzed based on the refraction angle of the water body.

[0029] Since the rectangular frame 12 is installed diagonally along the direction of water flow, when flowing water passes through the rectangular frame 12, it enters the interior of the rectangular frame 12 through the through-hole 13. Then, through sunlight illumination combined with the receiving spectrum of the two sets of remote sensing instruments 1, the ecological environment of the water body is detected. Simultaneously, the through-hole 13 can allow fine particles such as suspended matter and oil stains on the water surface to pass through, but cannot allow larger floating objects such as leaves and garbage to pass through. These floating objects are blocked by the sides of the rectangular frame 12 extending above the water surface, and thus, under the action of the water flow, they move along the rectangular frame... The side wall of 12 moves towards the collection basket 19 and eventually blocks the front of the collection net 21, thus preventing debris on the water surface from blocking sunlight and affecting the collection of the spectrum by the remote sensing instrument body 1. At this time, the water is relatively calm and static. When the water body being detected is flowing water with larger waves, the undulation of the water surface will increase, causing the float 14 to move up and down under the action of the water waves. During the upward movement of the float 14, the mounting bracket 11 will pull the pulling member 17 upward, which will cause the sliding rod 18 to overcome the rebound force of the elastic member 20 and move downward. As the collection basket 19 moves downwards, the rectangular frame 12 and the collection net 21 move upwards relative to the collection basket 19. This upward movement of the rectangular frame 12 follows the water waves, preventing surface debris from entering the rectangular frame 12. Simultaneously, the increased water flow during the surface movement causes debris obstructing the sides of the rectangular frame 12 to move towards the collection baskets 19. The downward movement of the collection baskets 19 then causes the debris to move from the sides of the rectangular frame 12 towards the collection net 21, where it is trapped inside the collection net 21 and collection basket 19. Furthermore, the downward movement of the water waves causes the rectangular frame 12 to move downwards, which in turn causes the collection basket 19 to move upwards, thus collecting the debris inside the collection basket 19. This structure effectively prevents debris from entering the rectangular frame 12 while simultaneously collecting it inside the collection basket 19, even when the water waves are large. Furthermore, as the rectangular frame 12 moves up and down with the water waves, the upper remote sensing detector 1 maintains its distance from the water surface, ensuring its detection distance remains unchanged.

[0030] This invention can avoid the impact of surface debris on the reflected light of suspended matter and bottom water when collecting water reflectance spectra through the remote sensing instrument body 1, thereby avoiding the impact on the detection effect of water quality and ecological environment. At the same time, it can also collect surface debris in water bodies with undulating waves, and use the spectral data collected by the two sets of remote sensing instruments body 1 to detect the position of suspended matter.

[0031] Example 2:

[0032] Based on Embodiment 1, a further improvement is made to the fixing mechanism, which includes a support rod 30 that is slidably connected to the mounting frame 11. An embedded plate 31 is fixedly connected to the lower end of the support rod 30. A balance component is fixedly installed on the embedded plate 31. A through groove is opened through the support rod 30 along the diagonal of the rectangular frame 12. A pulling component 17 enters the through groove and is fixedly connected to the mounting frame 11. A distance sensor 32 is fixedly installed at the top of the through groove.

[0033] During installation, the pre-embedded plate 31 is buried inside the riverbed, and then the two balancing components are installed along the direction of water flow, so that the two balancing components and the two L-shaped rods 16 form a 90-degree angle. In this way, after the L-shaped rods 16 and the collection basket 19 are subjected to the force of the water flow, the balancing components and the pre-embedded plate 31 can fix them and prevent the water flow from pushing the collection basket 19 over. At the same time, the distance sensor 32 is set to 0 by default in the initial state of the entire device installation, and then measures the position distance of the mounting frame 11 during the detection process to determine the water surface undulation of the detected water body, thereby avoiding the polarization spectrum caused by excessive water surface undulation from affecting the normal detection spectrum.

[0034] The lower end of the mounting bracket 11 is fixedly connected to a stop block 33 that matches the through groove. The part of the stop block 33 extending out of the through groove is provided with a first inclined surface 34. The stop block 33 can block the pull member 17 to prevent the water flow from driving the pull member 17 to move, thereby preventing the water flow from bending the pull member 17 and causing the mounting bracket 11 and the collection basket 19 to move downward together.

[0035] The balancing component includes a connecting ring 35 fixedly connected between two L-shaped rods 16, a pre-embedded plate 31, and a chain 36 fixedly installed on the connecting ring 35. An anchor 37 is fixedly connected to the middle of the chain 36. During installation, the anchor 37 is first poured into the water flow, causing it to sink into the riverbed. Then, the device is moved along the direction of the water flow to firmly install the anchor 37 inside the riverbed while tautening the chain 36. Finally, the pre-embedded plate 31 is pre-embedded inside the riverbed. In this way, the chain 36, the anchor 37, and the pre-embedded plate 31 form a stable triangle, which increases the device's resistance to deformation underwater. At the same time, the anchor 37 and the two collection baskets 19 are also triangularly distributed, making the two collection baskets 19 perpendicular to the water flow. In addition, the same anchor can be installed at the lower end of the two L-shaped rods 16 to increase the stability of the L-shaped rods 16 and prevent the entire device from shifting.

[0036] The mounting cylinder 15 is equipped with a solar panel, which includes two solar panels 38 and a battery assembly 39. The upper end of the mounting cylinder 15 is inclined with a second inclined surface 40. The two solar panels 38 are respectively installed on the upper ends of the two second inclined surfaces 40, and the battery assembly 39 is installed inside the mounting cylinder 15. The solar panels 38 and the battery assembly 39 work together to collect solar energy and then power the electrical components of the detection device.

[0037] The adjustment mechanism includes a threaded rod 41 that is rotatably connected to the mounting cylinder 15. The threaded rod 41 is threadedly connected to a hollow cylinder 42. The lower end of the hollow cylinder 42 is fixedly connected to a mounting plate 43. One set of remote sensing detector bodies 1 is installed at the lower end of the mounting plate 43. The upper end of the mounting plate 43 is fixedly connected to a limiting rod 44 that is slidably connected to the mounting cylinder 15.

[0038] During adjustment, simply rotating the threaded rod 41 will cause the empty cylinder 42 to move up and down. Since the empty cylinder 42 is fixedly connected to the mounting plate 43, and the mounting plate 43 is fixedly connected to the limiting rod 44, the limiting rod 44 can only slide up and down. Therefore, the mounting plate 43 and the empty cylinder 42 can only slide up and down, thereby allowing the height of the mounting plate 43 to be adjusted by rotating the threaded rod 41, thus accurately embedding the lower remote sensing instrument body 1 into the water for spectral collection.

[0039] A rotating assembly is installed at the lower end of the collection basket 19. The rotating assembly includes a mounting shaft 45 rotatably connected to the collection basket 19. An inclined fan blade assembly 46 is fixedly connected to the lower end of the mounting shaft 45. Several stirring rods 47 are fixedly connected to the mounting shaft 45 on the lower side of the collection basket 19. Several fixed rods 48 are fixedly connected inside the collection basket 19. During the up-and-down movement of the collection basket 19, the inclined fan blade assembly 46 will move up and down with the collection basket 19. Since the inclined fan blade assembly 46 is in an inclined state, the water flow will push the inclined fan blade assembly 46 to rotate in the opposite direction during the up-and-down movement, thereby driving the mounting shaft 45 and the several stirring rods 47 to rotate. When the mounting shaft 45 rotates, it will form a vortex that attracts the surrounding water flow. The stirring rods 47 can wrap the long strips of garbage around the stirring rods 47. Similarly, the several fixed rods 48 limit the garbage under the drive of the vortex. In this way, the garbage will be limited around the several stirring rods 47 or the fixed rods 48 and will not re-enter the water flow.

[0040] The mounting bracket 11 has crossbars 49 arranged in a cross pattern; such crossbars 49 can reduce the shading on the water surface, thereby facilitating the collection of the reflected and refracted spectrum of sunlight by the remote sensing instrument body 1.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
