Detailed implementation manners

[0023] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] As Figures 1-5 shown, a water quality detection selfie stick based on a multispectral camera includes a multispectral camera 18, a handle 5, and a box body 2 connected to the handle 5 through a telescopic joint. Specifically, in actual use, buttons can be set on the handle 5, and the user can control the shooting of the multispectral camera 18 through the buttons to achieve one-key operation. An embedded computing device can also be installed on the handle 5, which is connected to the multispectral camera 18 wirelessly or wiredly, responsible for receiving the image data transmitted by the camera. The captured multispectral images are transmitted to the embedded computing device wirelessly or wiredly to achieve fast data processing. The calculation results can be directly viewed by installing a display screen on the handle 5, or transmitted to a smart phone or computer through Bluetooth, Wi-Fi, etc. for further analysis.

[0026] In addition: the telescopic joint is specifically formed by a plurality of connecting tubes 1 which are sleeved together, and two adjacent connecting tubes 1 are plugged in, the box body 2 is rotatably connected to a threaded seat 3 which is threadedly connected to the telescopic joint, the upper surface of the threaded seat 3 is threadedly connected to the bottom edge of the inner wall of the connecting tube 1 located on the inner side among the plurality of connecting tubes 1, the box body 2 is fixedly connected to a motor 19, the end face of the main shaft of the motor 19 is plugged in to the bottom face of the threaded seat 3, the multispectral camera 18 is located in the box body 2, and is embedded below the motor 19, the threaded seat 3 is located at the back of the multispectral camera 18 and is fixedly connected to a scraper 17 which is slidably connected to the surface of the box body 2, and the box body 2 adopted in this scheme is made of transparent plastic or Glass material, after the box body 2 enters the water area of ​​different depths, the motor 19 starts. Because the main shaft of the motor 19 is installed on the threaded seat 3 connected to the expansion joint thread, the threaded seat 3 cannot rotate. Therefore, the housing part of the motor 19 will rotate relative to the main shaft, thereby realizing the rotation of the box body 2 relative to the threaded seat 3, so that the side of the box body 2 facing the multi-spectral camera 18 passes through the scraper 17, and the scraper 17 cleans the mud on the outer wall of the box body 2 or the suspended matter in the water to ensure that there is no interference within the camera range of the multi-spectral camera 18. In addition, a sealing gasket is set at the rotation point of the box body 2 and the threaded seat 3 to prevent water from entering and causing damage to the multi-spectral camera 18.

[0027] In order to realize the rapid extension and retraction of the telescopic joint: the end face of the handle 5 is fixedly connected to two mounting seats 4, and the two mounting seats 4 are rotatably connected with reels 7, and the two reels 7 are respectively wound with air pipes 8 and traction ropes 9, which pass through the handle 5 and extend into the telescopic joint. One end of the air pipe 8 is sleeved on one side of the threaded seat 3 and is connected to the inside of the box body 2. The other side of the threaded seat 3 is fixedly connected with a hollow tube 15, and the other end of the air pipe 8 is located on the reel 7. In addition, the handle 5 is located at the penetration of the air pipe 8 and the traction rope 9. The hole is hollowed out, so in actual use, in order to prevent the problem of water vapor caused by excessive temperature difference between the inside and outside of the box body 2 due to different temperatures at different water depths, hot air is poured into the port of the air pipe 8 on the reel 7. The hot air enters the box body 2 through the air pipe 8, heats and dries the wet air in the box body 2, and then enters the telescopic joint through the hollow tube 15, and finally sprays out along the hollow part of the handle 5, that is, to ensure that the box body 2 is in a dry and water vapor-free state, and to prevent the multi-spectral camera 18 from generating water mist and affecting the clarity:

[0028] One end of the towing rope 9 is tied to the upper surface of the threaded seat 3. On the same side of the two mounting seats 4, a sprocket 6 fixed to one end of the reel 7 is rotatably connected through both. The two sprockets 6 are driven by a chain, and a pin shaft 10 inserted into the side of the mounting seat 4 is provided through one end of one of the sprockets 6. By rotating and releasing the towing rope 9 with the other reel 7, under the action of gravity, the box body 2 can pull the telescopic joint to extend, so that the multi-spectral camera 18 in the box body 2 can enter waters of different depths. In addition, the two sprockets 6 provided can realize the simultaneous release of the two reels 7, and then realize the simultaneous release of the air pipe 8 and the towing rope 9. In addition, as shown in the figure, the side of the reel 7 is provided with an annular hollow, so inserting the pin shaft 10 into the hollow can prevent the sprocket 6 from rotating, and then realize the position fixation of the reel 7. In addition, in this solution, the motor 19 can also be installed on the handle 5. The main shaft of the motor 19 is used to drive the sprocket 6 to rotate quickly, so as to realize the quick release and winding of the towing rope 9 and the air pipe 8.

[0029] In order to prevent the telescopic joint from shaking during telescoping: Among the adjacent two connecting pipes 1, an arc-shaped block 16 is installed at the port of the inner connecting pipe 1. A elastic piece 14 inserted and embedded in the bottom edge of the inner wall of the outer connecting pipe 1 is fixedly connected to the top edge of the arc-shaped block 16. The top surface of the elastic piece 14 is flat. During actual use, after one of the connecting pipes 1 slides to the bottommost side of the other connecting pipe 1, the elastic piece 14 automatically embeds into the bottom edge of the inner wall of the adjacent outer connecting pipe 1, and the flat part of its top edge can fix the positions of the two connected connecting pipes 1 and prevent them from moving. Therefore, the elastic piece 14 provided can fix the position when the connecting pipe 1 is fully extended:

[0030] An embedded box 11 is fixedly connected through the top edge position of the inner wall of the connecting pipe 1. A rotating shaft 12 is rotatably connected in the embedded box 11 through a volute spring. A main rope 13 is wound around the rotating shaft 12. One end of the main rope 13 passes through one side of the upper surface of the arc-shaped block 16 and then extends through the other side of the bottom surface of the arc-shaped block 16 to be fixed to the swinging edge of the elastic piece 14. When the connecting pipe 1 extends, the elastic piece 14 pulls one end of the main rope 13 to move, so as to realize the rotating shaft 12 overcoming the elastic force of the volute spring and rotating to release the main rope 13 until the elastic piece 14 is embedded into the inner wall of the connecting pipe 1. A volute spring with an elastic force smaller than that of the elastic piece 14 and the gravity of the box body 2 can be selected. When recycling is needed, only manually or electrically rotate the rotating shaft 12, apply a greater force to the rotating shaft 12 to make the rotating shaft 12 rotate and wind up the main rope 13, so as to realize the main rope 13 pulling the elastic piece 14, and then the elastic piece 14 can be pulled out from the inner wall of the adjacent outer connecting pipe 1, and the corresponding connecting pipe 1 can be raised and reset.

[0031] Working principle: Place the multispectral camera 18 above the water body to be monitored. Rotate the winch 7 according to the detection depth to release the air pipe 8 and the towing rope 9, so that several connecting pipes 1 in the telescopic joint extend outwards in sequence until the box body 2 reaches the corresponding depth. Then, start the motor 19 to rotate the box body 2, and then use the scraper 17 to clean the surface of the box body 2. Then, start the multispectral camera 18 to take pictures through the control button. The taken multispectral images are transmitted to the embedded computing device wirelessly or by wire. The embedded computing device runs the built-in algorithm to process and analyze the images, and the calculation results are displayed on the display screen of the handle 5 or transmitted wirelessly to an external device.

[0032] The wiring diagrams of the multispectral camera 18 and the motor 19 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the multispectral camera 18 and the motor 19 will not be explained in detail.

[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
