Description

Technical Field

[0001] This utility model relates to the field of remote sensing devices, and more specifically, to a remote sensing device for investigating soil contaminated sites. Background Technology

[0002] Industries such as petrochemicals, metal mining and beneficiation, coking, electroplating, textile printing and dyeing, papermaking, and environmental remediation, especially tailings ponds involved in metal mining and beneficiation, often face significant challenges due to the long-standing loss of contact with owners and a severe lack of basic information. Many project sites are located in mountainous areas, inaccessible to investigators. The complex terrain of these mountainous regions presents immense difficulties and challenges to investigating the construction and current status of tailings pond sites. Therefore, remote sensing technology is necessary. Remote sensing utilizes the characteristics of different objects producing different electromagnetic waves to detect the reflection and emission of electromagnetic waves by surface objects, thereby extracting information about these objects and enabling long-distance object identification.

[0003] A search revealed that Chinese patent CN211494499U discloses a "remote sensing device for investigating soil contaminated sites," comprising a drone, a radar detection device mounted on the drone, and a camera. The drone's frame has a mounting plate with multiple locking components for securing the camera. Each locking component includes a vertically movable adjusting rod on the mounting plate and a horizontally movable abutting plate at the bottom of the adjusting rod for pressing against the camera. The horizontally movable abutting plate and the mounting plate form a mounting position for the camera. This remote sensing device for investigating soil contaminated sites facilitates the installation and removal of the camera on the drone and allows for the installation of cameras of different specifications. However, it still has the following drawbacks:

[0004] (1) The high-frequency vibrations during the flight of the UAV are directly transmitted to the camera, which can easily cause serious image blurring and shaking, greatly reducing the quality and clarity of the collected data and failing to meet the basic requirements of professional remote sensing analysis for image stability.

[0005] (2) When the drone is flying at low altitude, it is easy to be damaged by collisions if it encounters obstacles such as tree branches and weeds, which increases the equipment maintenance cost. Soil pollution site investigation often involves complex outdoor environments, and the camera is directly exposed to the outside, which is easily affected by rain and sand erosion, leading to equipment failure.

[0006] Therefore, a remote sensing device for investigating soil contaminated sites is proposed. Utility Model Content

[0007] The purpose of this invention is to address the current problem of insufficient effective vibration reduction, which easily leads to severe image blurring and jitter, significantly reducing the quality and clarity of collected data. This invention provides a remote sensing device for investigating soil-contaminated sites, thus solving the problems mentioned in the background section.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The present invention is as follows: a remote sensing device for investigating soil contaminated sites, including a drone and a camera, wherein a mounting plate is fixedly connected to the top of the drone, a fixing component for fixing the camera is connected to the top of the mounting plate, and a protective component for protecting the camera is hinged to the top of the mounting plate.

[0010] The fixing assembly includes a motor fixedly connected to one side of the mounting plate. A bidirectional screw is installed at the output end of the motor. A clamping plate is slidably installed on the bidirectional screw via a slider. Two sets of clamping plates are symmetrically arranged. Limiting holes are opened on the clamping plates. A placement plate is fixedly installed in the middle of the top of the mounting plate. A mounting groove is provided on the placement plate and the camera is snapped into the mounting groove.

[0011] As a preferred technical solution of this utility model, the protective component includes a vertical plate located at the top of the mounting plate, a transparent protective cover for protecting the camera is hinged in the middle of the vertical plate, the transparent protective cover has heat dissipation holes for dissipating heat from the camera, and positioning pins for fixing the protective cover are provided through the heat dissipation holes and corresponding limiting holes on the clamping plate.

[0012] As a preferred technical solution of this utility model, a first damper is fixedly installed on both the clamping plate and the placement plate. A first spring is fixedly connected to the other end of the first damper, and a rubber pad is fixedly connected to the other end of the first spring. The inner side of the rubber pad is tightly fitted to the outer side of the camera.

[0013] As a preferred technical solution of this utility model, a pad is fixedly installed on the bottom of the drone, a second spring is fixedly installed on the other end of the pad, a second damper is connected to the other end of the second spring, and an anti-slip pad is fixedly installed on the other end of the second damper.

[0014] As a preferred technical solution of this utility model, the mounting plate is provided with a limiting groove and the bidirectional screw is placed in the limiting groove. The four sets of positioning pins are located on both sides of the first spring and the positioning pins are fixed to the limiting hole by screwing.

[0015] As a preferred technical solution of this utility model, the clamping plates are symmetrically arranged on both sides of the placement plate, and the placement plate and the mounting plate are fixedly connected by bolts.

[0016] As a preferred technical solution of this utility model, the pad is fixedly connected to the drone by bolts, and four sets of pads are symmetrically arranged at the bottom of the drone.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Align the bottom of the camera with the mounting slot on the placement plate, then start the motor to drive the bidirectional screw to rotate. The bidirectional screw has threads in different directions, which cause the two sets of symmetrical clamps mounted on the slider to move towards or away from each other. Precisely control the movement of the clamps according to the size of the camera to clamp the camera. When the camera is subjected to external vibration or impact, the vibration energy is first transmitted to the rubber pad. The elastic deformation of the rubber pad absorbs some of the energy. Then, the remaining vibration energy is buffered by the further compression or stretching of the first spring. The first damper plays the role of consuming vibration energy, thereby reducing the impact of vibration on the camera and ensuring that the camera can work stably during the flight of the drone and capture clear and accurate images.

[0019] 2. Once the camera is installed, slowly rotate the transparent protective cover along the hinge point on the upright plate until it completely covers the camera. Precisely insert the positioning pin into the corresponding limiting hole. Tighten the positioning pin clockwise through the thread on one end, matching the threaded hole in the clamping plate and the limiting hole. This secures the transparent protective cover to the clamping plate, providing reliable protection for the camera. To remove the camera, simply rotate the positioning pin in the opposite direction to disengage it from the limiting hole. The transparent protective cover protects the camera from dust, rain, and impacts, preventing damage. The cooling holes ensure that the heat generated during operation is dissipated promptly, preventing overheating from affecting the camera's performance and lifespan. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] like Figures 1-5 As shown, this embodiment proposes a remote sensing device for investigating soil contaminated sites, including a drone 1 and a camera 2. A mounting plate 3 is fixedly connected to the top of the drone 1, a fixing component 4 for fixing the camera 2 is connected to the top of the mounting plate 3, and a protective component 5 for protecting the camera 2 is hinged to the top of the mounting plate 3.

[0031] The fixing component 4 includes a motor 401 fixedly connected to one side of the mounting plate 3. A bidirectional screw 402 is mounted on the output end of the motor 401. Two sets of clamping plates 403 are symmetrically arranged and slidably mounted on the bidirectional screw 402 via a slider. Limiting holes 404 are provided on the clamping plates 403. A placement plate 405 is fixedly mounted on the top center of the mounting plate 3. The placement plate 405 is provided with a mounting groove 406, and the camera 2 is snapped into the mounting groove 406. The bottom of the camera 2 is aligned and inserted into the mounting groove 406 on the placement plate 405. Then, the motor 401 is started, driving the bidirectional screw 402 to start rotating. The bidirectional screw 402 has threads in different directions. Through the different threads, the two sets of symmetrical clamping plates 403 mounted on the slider move towards or away from each other. The movement of the clamping plates 403 is precisely controlled according to the size of the camera 2, so that the clamping plates 403 clamp the camera 2, thereby achieving a stable fixation of the camera 2 and greatly improving the installation flexibility.

[0032] like Figures 1-5 As shown, the protective component 5 includes a vertical plate 501 located at the top of the mounting plate 3. A transparent protective cover 502 for protecting the camera 2 is hinged in the middle of the vertical plate 501. The transparent protective cover 502 has heat dissipation holes 503 for dissipating heat from the camera 2. A positioning pin 504 for fixing the protective cover is provided through the heat dissipation holes 503 and the corresponding limiting holes 404 on the clamping plate 403. Once the camera 2 is installed, slowly rotate the transparent protective cover 502 along the hinge point on the upright plate 501 until it completely covers the camera 2. Precisely insert the positioning pin 504 into the limiting hole 404 corresponding to the heat dissipation hole 503. Tighten the positioning pin 504 clockwise with the threaded end of the positioning pin 504 and the threaded hole in the clamping plate 403 and the limiting hole 404 to fix the transparent protective cover 502 to the clamping plate 403, providing reliable protection for the camera 2. To remove the camera 2, simply rotate the positioning pin 504 in the opposite direction to disengage it from the limiting hole 404, and it can be easily removed. The transparent protective cover 502 protects the camera 2 from dust, rain, and impact interference and damage. The heat dissipation hole 503 ensures that the heat generated by the camera 2 during operation can be dissipated in time, avoiding overheating that could affect the performance and lifespan of the camera 2.

[0033] like Figures 2-5As shown, a first damper 4061 is fixedly installed on both the clamping plate 403 and the placement plate 405. A first spring 4062 is fixedly connected to the other end of the first damper 4061, and a rubber pad 4063 is fixedly connected to the other end of the first spring 4062. The inner side of the rubber pad 4063 is tightly fitted to the outer side of the camera 2. When the camera 2 is subjected to external vibration or impact, the vibration energy is first transmitted to the rubber pad 4063. The elastic deformation of the rubber pad 4063 absorbs some of the energy. Then, the remaining vibration energy is buffered by the further compression or stretching of the first spring 4062. The first damper 4061 plays the role of consuming vibration energy, thereby reducing the impact of vibration on the camera 2, ensuring that the camera 2 can work stably during the flight of the UAV 1, capture clear and accurate images, and improve the reliability of the survey data.

[0034] like Figures 1-4 As shown, a pad 5041 is fixedly installed on the bottom of the drone 1. A second spring 5042 is fixedly installed on the other end of the pad 5041. A second damper 5043 is connected to the other end of the second spring 5042. An anti-slip pad 5044 is fixedly installed on the other end of the second damper 5043. When the drone 1 lands, the anti-slip pad 5044 contacts the ground first. Due to the high friction of the anti-slip pad 5044, it can prevent the drone 1 from sliding during landing. At the same time, the second spring 5042 and the second damper 5043 will be compressed under pressure. The elastic deformation of the second spring 5042 and the energy dissipation of the second damper 5043 can buffer the impact force of the drone 1 when landing, reducing the vibration impact on the internal structure of the drone 1 and the camera 2.

[0035] like Figures 1-5 As shown, a limiting groove 4064 is provided on the mounting plate 3, and the bidirectional screw 402 is placed in the limiting groove 4064. Four sets of positioning pins 504 are located on both sides of the first spring 4062, and the positioning pins 504 are screwed and fixed to the limiting hole 404 by threads. The limiting groove 4064 enables the slider to move stably in a straight line on the bidirectional screw 402, ensuring that the clamping plate 403 can move accurately in the predetermined direction, thereby achieving a stable fixation of the camera 2.

[0036] like Figures 2-5 As shown, clamping plates 403 are symmetrically arranged on both sides of the placement plate 405, and the placement plate 405 and the mounting plate 3 are fixedly connected by bolts. Driven by the bidirectional screw 402, the two sets of clamping plates 403 move towards each other, which can evenly apply clamping force to the camera 2 placed in the mounting groove 406 of the placement plate 405, ensuring that the camera 2 is subjected to balanced force during installation and will not tilt or be damaged due to uneven force.

[0037] like Figures 1-4As shown, the pad 5041 is fixedly connected to the drone 1 by bolts, and four sets of pads 5041 are symmetrically arranged at the bottom of the drone 1. When the drone 1 lands, the four sets of pads 5041 can evenly distribute the landing impact force, and through the buffering effect of the second spring 5042 and the second damper 5043, the vibration impact on the internal structure of the drone 1 and the camera 2 is reduced.

[0038] Specifically, when using the remote sensing device for soil contaminated site investigation: Align the bottom of camera 2 and insert it into the mounting slot 406 on the placement plate 405. Then, start the motor 401 to drive the bidirectional screw 402 to rotate. The bidirectional screw 402 has threads in different directions, which cause the two sets of symmetrical clamping plates 403 mounted on the slider to move towards or away from each other. The movement of the clamping plates 403 is precisely controlled according to the size of camera 2, allowing them to clamp camera 2 securely. Once camera 2 is installed, slowly rotate the transparent protective cover 502 along the hinge point on the upright plate 501 until it completely covers camera 2. Precisely insert the positioning pin 504 into the limiting hole 404 corresponding to the heat dissipation hole 503. The thread on one end of the positioning pin 504 is clockwise tightened with the threaded hole in the clamping plate 403 and the limiting hole 404 to fix the transparent protective cover 502 to the clamping plate 403, providing reliable protection for the camera 2. When the camera 2 is removed, simply rotate the positioning pin 504 in the opposite direction to disengage it from the limiting hole 404, and it can be easily removed. When the camera 2 is subjected to external vibration or impact, the vibration energy is first transmitted to the rubber pad 4063. The elastic deformation of the rubber pad 4063 absorbs some of the energy. Then, the remaining vibration energy is buffered by the further compression or stretching of the first spring 4062. The first damper 4061 plays the role of consuming vibration energy, thereby reducing the impact of vibration on the camera 2 and ensuring that the camera 2 can work stably during the flight of the drone 1.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
