Therefore, theoretical basis and basic parameters are provided for identifying the black and odorous water body of the unmanned aerial vehicle image by analyzing the spectrum emission characteristics of the black and odorous water body and intensively researching the spectrum emission characteristics of the visible light wave band.

The input end of the gear transmission mechanism 312 is the transmission connection between the main gear 3123 and the synchronous belt machine 313. When the sample collector 31 is started, the synchronous motor 313 drives the main gear 3123 to rotate, when the main gear 3123 is in meshing transmission with the first sub-gear 3122, the second sub-gear 3124 is still, when the first sub-gear 3122 rotates one circle, the main gear 3123 is in meshing transmission with the second sub-gear 3124, at this time, the first sub-gear 3122 is still, and so on, it can be known that there is always one still between the first sub-gear 3122 and the second sub-gear 3124, and since there is one executing member for each of the first sub-gear 3122 and the second sub-gear 3124, the two executing members can realize the matching movement.
According to a specific embodiment of the present invention, the gear transmission mechanism 312 includes a gear mounting plate 3121, a first sub gear 3122, a main gear 3123, a second sub gear 3124, a turntable support shaft 3125, a main pulley 3126, and a sub pulley 3127, the sub pulley 3127 is in belt transmission connection with the main pulley 3126, and the diameter of the sub pulley 3127 is smaller than that of the main pulley 3126 so as to increase the rotation speed of the sub pulley 3127. The synchronous motor 313 is in transmission connection with the main gear 3123, and the main pulley 3126 is coaxially disposed with the first pinion 3122 through the gear mounting plate 3121, so that the number of rotations of the main pulley 3126 and the first pinion 3122 is identical. The first pinion gear 3122 is in driving connection with the main gear 3123, the main gear 3123 is in driving connection with the second pinion gear 3124, and both the first pinion gear 3122 and the second pinion gear 3124 are in meshing driving connection with the toothed portion 31233 of the main gear 3123.

And the peristaltic pump 311 is in transmission connection with the secondary pulley 3127. When the second auxiliary gear 3124 completes one rotation, the first auxiliary gear 3122 starts to rotate, since the first auxiliary gear 3122 is coaxially disposed with the primary pulley 3126, the angular velocity of the first auxiliary gear 3122 is equal to that of the primary pulley 3126, and further, the primary pulley 3126 is in transmission connection with the auxiliary pulley 3127 through a belt, so the linear velocity of the rotation of the primary pulley 3126 is equal to that of the auxiliary pulley 3127;
according to the relation between the rotating speed n and the linear velocity v;
n＝1/T＝v/2πr
when the linear speeds v of the two pulleys are the same, the smaller the radius r, the larger the rotation speed N, and the smaller the radius r, the larger the rotation speed N, since the radius of the secondary pulley 3127 is smaller than that of the primary pulley 3126, the rotation speed can be greatly increased, which is in turn beneficial for the peristaltic pump 311 to collect enough samples.
According to a specific embodiment of the present invention, the main gear 3123 is provided with a positioning stop pin 31231, a non-toothed portion 31232 and a toothed portion 31233, the positioning stop pin 31231 is inserted on the non-toothed portion 31232, the non-toothed portion 31232 is connected with the toothed portion 31233 end to end, and the gear portion of the second sub-gear 3124 and the gear portion of the first sub-gear 3122 are in meshing transmission connection with the toothed portion 31233; it should be specifically noted that only one of the second counter gear 3124 and the first counter gear 3122 can be in meshing transmission with the main gear 3123 at all times. The second counter gear 3124 is identical in structure to the first counter gear 3122, and the first and second counter gears 3122 and 3124 are each provided with an arcuate notch 6, the arcuate notches 6 of the second counter gear 3124 and the arcuate notches 6 of the first counter gear 3122 each abut against the non-toothed portion 31232. It is hereby achieved that between the second counter gear 3124 and said first counter gear 3122 there is always one which can be in mesh transmission with the main gear 3123, while the other remains stationary.
According to an embodiment of the present invention, a shift lever 5 is disposed on each of an end surface of the first counter gear 3122 and an end surface of the second counter gear 3124, the shift lever 5 of the first counter gear 3122 abuts against the positioning stop pin 31231, and the shift lever 5 of the second counter gear 3124 abuts against the positioning stop pin 31231 and the sample storage turntable 314, respectively. When the main gear 3123 rotates, the positioning stop pin 31231 rotates around the axis of the main gear 3123, and at the time when the non-toothed portion 31232 leaves the arc notch 6, the positioning stop pin 31231 collides with the shift lever 5, so that the toothed portion 31233 can be in meshing transmission with the first secondary gear 3122, and the first secondary gear 3122 drives the main pulley 3126 to rotate together, and the secondary pulley 3127 is accelerated to increase the rotation speed, so that the peristaltic pump 311 can draw a sufficient sample.
According to an embodiment of the present invention, the sample storage turntable 314 includes a turntable 3141, a test tube rack 3142 and a sampling test tube 3143, and the front end of the turntable support shaft 3125 is inserted into the axis of the turntable 3141, so that the turntable 3141 can freely rotate around the axis. The rotary disc 3141 is provided with a plurality of test tube racks 3142, any one of the test tube racks 3142 is provided with one sampling test tube 3143, and the test tube racks 3142 can protect the test tubes and prevent the test tubes from being damaged. In addition, when the toothless portion 31232 leaves the arc notch 6, the positioning stop pin 31231 collides with the shift lever 5, and at this time, the shift lever 5 of the second auxiliary gear 3124 rotates around the center of the second auxiliary gear 3124 by one circle, in this process, the shift lever 5 shifts the test tube rack 3142, so that the turntable 3141 rotates by a certain angle, and thus the sampling test tube 3143 is always located at the lower end of the liquid outlet of the peristaltic pump 311, further, the shift lever 5 is stationary during the next rotation of the turntable 3141, the turntable 3141 remains stationary, at this time, the peristaltic pump 311 extracts a sample and injects the sample into the test tube 3143, and after the peristaltic pump 311 finishes one sample collection, the previous step can be performed in a circulating manner, and thus a plurality of different samples can be collected.
According to a specific embodiment provided by the invention, the buoyancy chassis 4 comprises a limiting mechanism 41, two buoys 42 and a shifting piece rod 43, the limiting mechanism 41 is arranged at the lower end of the body 2, the two buoys 42 are fixedly arranged on the limiting mechanism 41, the buoys 42 can enable the unmanned aerial vehicle to stay on the water surface, so that the unmanned aerial vehicle can conveniently collect water samples, and the limiting mechanism 41 can enable the two buoys 42 to synchronously open, so that the unmanned aerial vehicle can stably stay on the water surface. Two shifting piece rods 43 are movably inserted in the limiting mechanism 41 and used for shifting garbage floating on the water surface, and the garbage is prevented from interfering the unmanned aerial vehicle to collect a water sample.

When unmanned aerial vehicle frame floats on the surface of water, under the effect of unmanned aerial vehicle gravity, fixed bolster 413 expandes, and the plectrum 432 that floats under the effect of water surface buoyancy simultaneously stops all the time on the surface of water, at the in-process that fixed bolster 413 expandes, and the plectrum 432 that floats also can expand along with it to dial the floater on the surface of water, thereby avoid hindering unmanned aerial vehicle collection sample.
