Description

Technical Field

[0001] The present invention belongs to the technical field of science popularization display systems and equipment, and specifically relates to a science popularization display system for quantifying the effects of pollution reduction and carbon reduction in forest wetland composite ecology. Background Art

[0002] The forest wetland complex ecosystem is an important carbon sink that can absorb and store large amounts of carbon dioxide. However, due to the impact of human activities, forest wetlands are facing serious degradation and destruction, resulting in the weakening of their carbon sink function. Through pollution reduction and carbon reduction management, the carbon sink function of forest wetlands can be restored and enhanced, which will help cope with climate change and slow down the trend of global warming.

[0003] In order to popularize the importance of pollution reduction and carbon reduction management of forest wetland complex ecology and show people the pollution reduction and carbon reduction management effect of forest wetland complex ecology, generally a popular science display system is used to show people the changes in soil pollution and water pollution levels of forest wetland complex ecology at different stages before and after management, and through the comparison of quantitative indicators, people can understand the pollution reduction and carbon reduction management effect, so as to popularize the importance of pollution reduction and carbon reduction management and let more people participate in the practical operation of pollution reduction and carbon reduction. The popular science display system generally includes a sampling module, a detection module, and a display module. The sampling module is used to sample soil samples and water samples of forest wetland complex ecology at different stages after management.

[0028] like Figure 1-6 As shown, a system for quantifying and popularizing the effects of pollution reduction and carbon reduction in forest wetland composite ecology includes a detection module and a display module. The detection module is used to detect and analyze soil samples and water samples of forest wetlands. The display module performs quantified and popularizing the effects of pollution reduction and carbon reduction in forest wetland composite ecology based on the detection and analysis results of soil samples and water samples.

[0029] A sampling extension port is provided at the bottom of the fixed parking frame 1, and the soil sampling component and the water sampling component extend from the sampling extension port to sample soil samples on the slope where the river and soil of the forest wetland meet, and water samples in the river adjacent to the soil sample.

[0030] It should be noted that, in this embodiment, the detection module is a water quality detector for detecting water samples and a soil pollution detector for detecting soil samples, both of which are prior arts and will not be described in detail here;

[0031] The display module can display the test and analysis results of soil and water samples before treatment and the test and analysis results of soil and water samples in different time periods after pollution reduction and carbon reduction treatment by means of bar graphs, line graphs, trend graphs and other quantitative indicators to form a comparison, thereby achieving a quantitative popular science display effect of the pollution reduction and carbon reduction effectiveness of the forest wetland complex ecology.

[0032] Preferably, the soil sampling assembly includes a fixing frame 1 5 and a fixing frame 2 6 arranged at the bottom of the drone 2, two rotating shafts 7 rotatably connected to the fixing frame 1 5 and the fixing frame 2 6 respectively, and a conveyor belt 8 sleeved between the two rotating shafts 7, wherein the conveyor belt 8 is arranged obliquely and the side close to the fixing frame 2 6 is the lower side, and the conveyor belt 8 is divided into an installation area and a blank area, and a plurality of digging buckets 9 are arranged at equal intervals on the installation area;

[0033] The soil sampling assembly further comprises a power assembly for driving the conveyor belt 8 for transmission, a soil storage assembly, and a scraping assembly for pushing the soil sample excavated by each digging bucket 9 into the interior of the soil storage assembly.

[0034] Preferably, the soil storage assembly includes two soil storage boxes 26 respectively arranged on the front and rear sides of the fixing frame 5, a fixing seat 24 arranged on the fixing frame 5 and located on the upper and lower sides of the soil storage box 26, a sliding connection block 25 slidably connected to the fixing seat 24 and fixedly connected to the soil storage box 26, and a spring 27 arranged between the fixing seat 24 and the sliding connection block 25. The soil storage box 26 contacts the side wall of the excavation bucket 9 under the pressure of the spring 27, and a receiving interface is provided on the side of the soil storage box 26 close to the excavation bucket 9.

[0035] Preferably, the scraping assembly includes a frame 28 slidably connected to the fixed frame 5 up and down, a screw rod 29 rotatably connected to the frame 28, a servo motor 33 driving the screw rod 29 to rotate, a nut seat 30 connected to the screw rod 29 through a ball nut pair, a scraper 31 provided on the nut seat 30, and an electric push rod 32 provided on the fixed frame 5 for driving the frame 28 to move up and down; it should be noted that, in this embodiment, the nut seat 30 is slidably connected to the frame 28 to limit the reciprocating movement of the nut seat 30 along the screw rod 29.

[0036] Preferably, the water sampling assembly includes two support frames 10 symmetrically arranged on the fixing frame 2 6, a middle partition 11 arranged between the two support frames 10, an electric push rod 17 arranged on the middle partition 11, a liquid suction head 18 arranged at the bottom of the telescopic end of the electric push rod 17, a liquid storage tank 21 arranged at the bottom of the drone 2, a delivery pipe 19 arranged between the liquid suction head 18 and the liquid storage tank 21, and a delivery pump 20 arranged on the delivery pipe 19;

[0037] The sampling component also includes a waterweed pressing component, and the waterweed pressing component is driven by a power component.

[0038] Preferably, the water grass pressing assembly includes two screw rods 12 rotatably connected to the support frame 10 and the middle partition plate 11 respectively, a nut seat 13 connected to the screw rod 12 through a ball nut pair, and a mesh plate 14 arranged on the nut seat 13. The two mesh plates 14 are symmetrically arranged front to back and have mesh plates 15 at the bottom. The two mesh plates 15 are staggered up and down, and the two screw rods 12 rotate to make the two mesh plates 14 move toward or away from each other. It should be noted that in this embodiment, a plurality of guide rods 121 for guiding the movement of the nut seat 13 are provided between the support frames 10, and the guide rods 121 are used to limit the reciprocating movement of the nut seat 13 along the screw rod 12.

[0039] Preferably, the power assembly includes an auxiliary rotating shaft 22 arranged on the fixing frame 2 6 , a servo motor 23 driving the auxiliary rotating shaft 22 to rotate, and a synchronization member 16 is provided between the rotating shaft 7 and the auxiliary rotating shaft 22 and between the screw 12 and the auxiliary rotating shaft 22 .

[0040] It should be noted that, in this embodiment, the synchronous member 16 is composed of two synchronous wheels and a synchronous belt arranged between the two synchronous wheels.

[0041] When it is necessary to sample soil samples and water samples for testing, the drone 2 flies with the soil sampling assembly and the water sampling assembly and lands inside the fixed parking frame 1. At this time, the soil sampling assembly and the water sampling assembly extend downward from the sampling extension port. The staff can observe the distance between the soil sampling assembly and the slope at the intersection of the river and the soil in the forest wetland, and the distance between the water sampling assembly and the river surface in real time through the remote monitoring camera, so as to adjust the height of different electric telescopic support legs 3;

[0042] Then, the servo motor 23 is started. The operation of the servo motor 23 drives the auxiliary shaft 22 to rotate. The rotation of the auxiliary shaft 22 drives the screw 12 to rotate through the synchronous member 16 connected to the auxiliary shaft 22 and the screw 12. When the screw 12 rotates, the two nut seats 13 move away from each other, and the two mesh plates 14 and the mesh plate 2 15 gradually move away from each other. The mesh plate 2 15 presses the herbs in the water body and presses them down, making it convenient for the subsequent liquid suction head 18 to extend downward to extract water samples. Then, the servo motor 23 is turned off and the electric push rod 17 is started. The electric push rod 17 drives the liquid suction head 18 to move down into the water, and the delivery pump 20 is started. The delivery pump 20 uses the liquid suction head 18 and the delivery pipe 19 to extract the water sample and deliver it to the inside of the delivery pump 20. After the water sample sampling is completed, the delivery pump 20 is turned off, and the electric push rod 17 drives the liquid suction head 18 to move up and reset;

[0043] It should be noted that before and when the water samples were drawn, the side of the slope where the river and the soil meet near the forest wetland was a blank area of ​​the conveyor belt 8, that is, the digging bucket 9 was not rotated to contact the soil, so as to prevent the sampled water from being contaminated;

[0044] When the liquid suction head 18 moves up and resets, the servo motor 23 is started again. The operation of the servo motor 23 drives the auxiliary shaft 22 to rotate. The rotation of the auxiliary shaft 22 drives the rotating shaft 7 to rotate through the synchronous member 16 connected to the auxiliary shaft 22 and the rotating shaft 7. The rotation of the rotating shaft 7 drives the conveyor belt 8 to drive. The conveyor belt 8 drives the digging bucket 9 to gradually contact the slope where the river and the soil of the forest wetland meet and dig the soil sample of the slope where the river and the soil of the forest wetland meet. Each digging bucket 9 reaches two soil storage boxes 2 6, the servo motor 1 23 is turned off, the electric push rod 2 32 is started to drive the frame 28, the screw rod 29, the nut seat 2 30, and the scraper 31 to move downward, until the scraper 31 extends to the inside of the digging bucket 9, the electric push rod 2 32 is turned off, and the servo motor 2 33 is started. The servo motor 2 33 drives the screw rod 29 to rotate, so that the nut seat 2 30 moves along the screw rod 29, thereby driving the scraper 31 to move the soil excavated from the inside of the digging bucket 9 to leak out from the side of the digging bucket 9 and fall into the soil storage box 26 through the receiving interface;

[0045] It should be noted that when the digging bucket 9 is located between the two soil storage boxes 26, the soil storage box 26 will be pressed against the side of the digging bucket 9 under the elastic force of the spring 27, so that the soil leaking from the digging bucket 9 can fall into the soil storage box 26 through the receiving interface.

[0046] When the soil inside the digging bucket 9 is scraped off, the electric push rod 2 32 drives the frame 28, the screw rod 29, the nut seat 230, and the scraper 31 to move up and reset, and the servo motor 1 23 is started again to drive the conveyor belt 8 to transmit until the next digging bucket 9 reaches between the two soil storage boxes 26 again and pauses again, and the electric push rod 2 32 drives the scraper 31 to move down and the servo motor 2 33 drives the scraper 31 to move to scrape the soil inside the digging bucket 9. This is repeated until the soil inside all the digging buckets 9 is scraped off, and the servo motor 1 23 is started to reverse. The servo motor 1 23 reverses to close the two mesh plates 14. When the servo motor 1 23 reverses, the two mesh plates 14 will move toward each other.

[0047] It should be noted that, in this embodiment, the drone 2, remote monitoring camera, electric telescopic support legs 3, electric moving wheels 4, servo motor 1 23, servo motor 2 33, electric push rod 1 17, electric push rod 2 32, and delivery pump 20 can all be remotely controlled.

[0048] Preferably, the liquid storage box 21 is provided with an output pipe and a switch valve is provided on the output pipe. By opening the switch valve on the output pipe of the liquid storage box 21, the water sample stored in the liquid storage box 21 can be transported out, so that the staff can manually use the detection module to detect the water sample.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
