[0024] Reference Figure 1 A collection device for forest carbon sink detection includes a bracket 1, a lifting mechanism 2, a first driving mechanism 3, an adjusting mechanism 4, a second driving mechanism 5, and a collecting mechanism 6. The bracket 1 is arranged along the height direction, and the bottom surface of the bracket 1 is respectively fixed with supporting feet 11 at the four end corners. The lifting mechanism 2 is arranged on the bracket 1, and is used to adjust the height of the collecting mechanism 6. The adjusting mechanism 4 is used to adjust the angle of the collecting mechanism 6, which is convenient for detection in various directions. The first driving mechanism 3 and the second driving mechanism 5 are respectively used to provide power for the lifting mechanism 2 and the adjusting mechanism 4. The collecting mechanism 6 is used to collect carbon dioxide for detection. When in use, the bracket 1 is fixed, and the lifting mechanism 2 is started first according to needs to adjust the height of the collecting mechanism 6, and then the adjusting mechanism 4 is started according to needs to adjust the angle of the collecting mechanism 6, which is convenient for detection in multiple directions, saving time and effort.

[0025] Reference Figure 1The lifting mechanism 2 includes a screw 21, a spline shaft 22, and a fixed block 23. The screw 21 is arranged along the height direction of the bracket 1, and the top end of the screw 21 is rotatably connected to the top plate of the bracket 1, and the bottom end passes through the bottom plate of the bracket 1 and is rotatably connected thereto.

A mounting plate 231 is fixedly arranged at the top of the fixed block 23 away from one end of the screw 21. The mounting plate 231 is arranged parallel to the bottom surface of the fixed block 23, and the adjustment mechanism 4 and the collection mechanism 6 are both arranged on the mounting plate 231.

[0026] Reference Figure 1 and Figure 2 The first driving mechanism 3 includes a first motor 31, a first pulley 32, and a second pulley 33. The first motor 31 is fixed on the top surface of the bottom plate of the bracket 1, and the output shaft of the first motor 31 passes through the bottom plate of the bracket 1 and is rotatably connected thereto. The first pulley 32 is fixed on the output shaft of the first motor 31, and the second pulley 33 is fixed on one end of the screw 21 passing through the bottom plate of the bracket 1, and the first belt 34 is sleeved on the first pulley 32 and the second pulley 33.

[0027] When in use, the first motor 31 is started, and the first motor 31 drives the first pulley 32 to rotate. Due to the connecting effect of the first belt 34, the second pulley 33 can also be rotated, thereby rotating the screw 21. Due to the limiting effect of the spline shaft 22, the fixed block 23 can only be moved along the height direction of the screw 21, thereby adjusting the height of the fixed block 23, and then adjusting the height of the collection mechanism 6.

[0028] Reference Figure 1 , Figure 3 and Figure 4, the adjusting mechanism 4 includes a first mounting block 41, a first connecting rod 42, a first bevel gear 43, a second bevel gear 44, a second mounting block 45, a second connecting rod 46, and a third bevel gear 47. The first mounting block 41 is arranged in a "U" shape and is fixed on the mounting plate 231. Rotating rods 48 are rotatably connected to the tops of the two side walls of the first mounting block 41, and both ends of the rotating rod 48 pass through the two side walls of the first mounting block 41. The first connecting rod 42 is vertically arranged with respect to the top surface of the mounting plate 231, and the bottom end of the first connecting rod 42 passes through the first mounting block 41 and the mounting plate 231 respectively and is rotatably connected to both of them. The first bevel gear 43 is fixed on the top end of the first connecting rod 42, the second bevel gear 44 is fixed on the rotating rod 48 and meshes with the first bevel gear 43. The second mounting block 45 is arranged in an inverted "U" shape, and the two side walls of the second mounting block 45 are fixedly connected to the two ends of the rotating rod 48 passing through the first mounting block 41. The second connecting rod 46 is also vertically arranged with respect to the top surface of the mounting plate 231, is arranged on the top of the second mounting block 45, and the bottom end of the second connecting rod 46 passes through the top of the second mounting block 45 and is rotatably connected to it, and the top end is connected to the collecting mechanism 6. The third bevel gear 47 is fixed on the bottom end of the second connecting rod 46 and meshes with the second bevel gear 44. The second driving mechanism 5 provides power for the adjusting mechanism 4.

[0029] Referring to Figure 3 and Figure 5 , the second driving mechanism 5 includes a second motor 51, a third pulley 52, a fourth pulley 53, a fifth pulley 54, and a sixth pulley 55. The second motor 51 is fixed on the top surface of the bottom plate of the bracket 1 on one side of the first motor 31, and the output shaft of the second motor 51 passes through the bottom plate of the bracket 1 and is rotatably connected to it. The third pulley 52 is fixed on the output shaft of the second motor 51, the fourth pulley 53 is fixed on one end of the spline shaft 22 passing through the bottom plate of the bracket 1, and a second belt 56 is sleeved on the third pulley 52 and the fourth pulley 53. A gantry 57 is fixedly arranged on the inner bottom surface of the fixed block 23 on the side of the spline shaft 22 close to the collecting mechanism. The gantry 57 is arranged along the width direction of the fixed block 23. A rotating shaft 58 is rotatably connected between the gantry 57 and the bottom surface of the fixed block 23. A gear 581 is fixed on the rotating shaft 58 and meshes with the keyway of the spline shaft 22. The fifth pulley 54 is fixed on the rotating shaft 58 below the gear 581, the sixth pulley 55 is fixed on the bottom end of the first connecting rod 42, and a third belt 59 is sleeved on the fifth pulley 54 and the sixth pulley 55.

[0030] When in use, the second motor 51 is started, and the second motor 51 can drive the third pulley 52 to rotate. Due to the connection effect of the second belt 56 and the fourth pulley 53 fixed on the spline shaft 22, the spline shaft 22 can be driven to rotate, which also makes the fifth pulley 54 rotate. Due to the connection effect of the third belt 59, the sixth pulley 55 is rotated, so that the first connecting rod 42 is rotated, driving the first bevel gear 43 to rotate. Since the first bevel gear 43 and the second bevel gear 44 are meshed, the second bevel gear 44 is driven to rotate. Since the second bevel gear 44 is fixed on the rotating rod 48, the rotating rod 48 is rotated, and then the second mounting block 45 is rotated with the rotating rod 48 as the axis; since the second bevel gear 44 and the third bevel gear 47 are meshed, the third bevel gear 47 is rotated, thereby rotating the second connecting rod 46, and finally rotating the collecting mechanism 6, so as to achieve the adjustment of various directions of the collecting mechanism 6.

[0031] Reference Figure 1 and Figure 6 The collection mechanism 6 includes a detection box 61, an air inlet duct 62, an air inlet tube 63, and an insect repellent component 64. The detection box 61 is hollow inside and fixed at the top of the second connecting rod 46. The air inlet duct 62 is arranged perpendicular to the axis of the screw 21, and the air inlet duct 62 is fixed on the side wall of the detection box 61 and communicated with the inside thereof. A fan (not shown in the figure) is also fixed in the air inlet duct 62. The air inlet tube 63 is also arranged perpendicular to the axis of the screw 21, and is fixed on the side of the air inlet duct 62 away from the detection box 61 and communicated with the inside thereof. A dustproof net 631 is fixed at one end of the air inlet tube 63 away from the detection box 61. A baffle 632 is fixed on the side wall of the detection box 61 above the air inlet tube 63 to block rainwater.

[0032] Reference Figure 6 and Figure 7 The insect repellent assembly 64 includes an insect repellent light strip 641 and an insect repellent box 642. The insect repellent light strip 641 is fixed on each side wall of the detection box 61. The insect repellent box 642 is fixed on the side wall of the detection box 61 below the air inlet 63, and the insect repellent box 642 is hollow inside. A liquid inlet pipe 6421 is fixed on the top of the insect repellent box 642. The liquid inlet pipe 6421 is connected to the inside of the insect repellent box 642, and a cover 6422 is hinged on the liquid inlet pipe 6421. A plurality of air holes 6423 are evenly opened on the cover 6422.

[0033] When in use, start the fan to suck air into the detection box 61 through the filter of the dustproof net 631, open the cover 6422, pour the insect repellent liquid into the insect repellent box 642 from the liquid inlet pipe 6421, and then close the cover 6422. The insect repellent liquid will evaporate from the air holes 6423 on the cover 6422 to repel insects. Driving the light strip 641 can also repel insects and reduce the number of small flying insects entering the detection box 61.

[0034] The operating principle of the present application is: when in use, the operator starts the first driving mechanism 3 according to the needs, and can adjust the position of the detection box 61 through the lifting mechanism 2, and then starts the second driving mechanism 5 according to the needs, and can adjust the angle of the detection box 61 through the adjustment mechanism 4, so that the detection box 61 can detect the air in multiple directions, saving time and effort and facilitating the use of the operator.
