Description

Technical Field

[0001] The invention relates to the technical field of survey equipment, and in particular to a wetland plant community diversity survey equipment. Background Art

[0002] Wetland plant communities are combinations of various plant species that live together regularly in wetland environments. Mangroves are wetland woody plant communities composed of evergreen trees or shrubs with mangroves as the main body, growing in the intertidal zones of tropical and subtropical coasts. They play an extremely important role in purifying seawater, preventing wind and waves, maintaining biodiversity, and fixing and storing carbon. Researchers usually use ordinary portable sampling boxes to collect plants in wetland parks. Researchers put the collected plants into the sampling boxes. Wetland plant sampling is often required in biological research such as genetic material extraction, respiration measurement, chlorophyll determination, and soil microbial measurement. In order to ensure the accuracy of the samples taken, the samples are often individually marked and stored.

[0003] Application No. CN202211413426.0 proposes a plant community sampling and investigation equipment for wetland protection, which can adjust the ventilation area by adjusting the length of the roller shutter cover on the window frame according to the ventilation requirements required for different sample collection.

[0004] When this sampling survey equipment is in use, the ventilation area is adjusted by adjusting the opening and closing size of the rolling shutter cover, regardless of the wind speed in the environment. If the wind speed is fast, the samples collected in the sampling box will dry quickly, while if the wind speed is slow, the samples collected in the sampling box will become moldy. The wind speed changes, but the opening and closing size of the rolling shutter cover does not change. Summary of the invention

[0005] The purpose of the present invention is to propose a wetland plant community diversity survey device to solve the problem in the background technology that the ventilation volume of the sample in the sampling box cannot be adjusted accordingly due to the change of wind speed.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example 1

[0036] This embodiment provides a wetland plant community diversity survey device, such as Figure 1 As shown, it includes a collecting box 1, a ventilation port 2 is provided on the top of the collecting box 1, a sample drawer 3 is slidably connected to the inner wall of the collecting box 1, and a fan 5 is arranged on the top of the collecting box 1; a base 4 is fixedly installed on the top of the collecting box 1 near the edge, the top of the base 4 is fixedly connected to the fan 5, a plurality of ventilation ports 2 are provided, and a collecting slot is provided on the top of the sample drawer 3, and the position of the collecting slot corresponds to the position of the ventilation port 2.

[0037] like Figure 2 and 3As shown, a wind displacement assembly 6 is provided on the side of the fan 5, and the wind displacement assembly 6 includes a wind shaft 61, a guide rod 62, a centrifugal block 64, a slip ring 66, an adjustment ring 67 and a linkage rod 68. The wind shaft 61 is fixedly installed at the center of the fan 5, and the guide rod 62 is fixedly installed at the rod body of the wind shaft 61. A plurality of guide rods 62 are provided and are distributed in a ring-shaped manner with equal angles around the wind shaft 61. The centrifugal block 64 slides on the rod body of the guide rod 62. The end of the wind shaft 61 is fixedly connected to a limit ring 63. The guide rod 62 guides the centrifugal block 64, and the limit ring 63 limits the centrifugal block 64.

[0038] like Figure 3 As shown, the side of the centrifugal block 64 is hinged to the linkage rod 68, and the other end of the linkage rod 68 is hinged to the slip ring 66. The side of the slip ring 66 away from the linkage rod 68 is rotatably connected to the adjustment ring 67. Both the slip ring 66 and the adjustment ring 67 slide on the shaft of the wind shaft 61.

[0039] The fan 5 is rotated by the action of wind, and the wind force is converted into centrifugal force. The fan 5 drives the wind shaft 61 to rotate, so that the centrifugal block 64 on the guide rod 62 is subjected to the rotational centrifugal force, and the centrifugal block 64 moves away from the wind shaft 61. The centrifugal block 64 pulls the slip ring 66 by the linkage rod 68, and the slip ring 66 pulls the adjusting ring 67 to move. The greater the wind force, the greater the distance between the centrifugal block 64 and the wind shaft 61, and the adjusting ring 67 moves to the right; the smaller the wind force, the smaller the distance between the centrifugal block 64 and the wind shaft 61, and the adjusting ring 67 moves to the left.

[0040] like Figure 3 As shown, a centrifugal spring 65 is elastically connected between the centrifugal block 64 and the wind shaft 61, and the guide rod 62 passes through the center of the centrifugal spring 65. When the wind force is strong, the centrifugal force exerted on the centrifugal block 64 is greater than the elastic force of the centrifugal spring 65, and the centrifugal block 64 moves away from the wind shaft 61; when the wind force is weak, the centrifugal force exerted on the centrifugal block 64 is less than the elastic force of the centrifugal spring 65, and the centrifugal block 64 is reset by the elastic force of the centrifugal spring 65.

[0041] like Figure 4 and 5 As shown, a ventilation adjustment assembly 8 is provided inside the collection box 1, and the ventilation adjustment assembly 8 includes a docking rod 81, a slide plate 82 and a shielding piece 84. The slide plate 82 is fixedly installed at the bottom of the docking rod 81, and the side of the slide plate 82 is fixedly connected to the shielding piece 84. The bottom of the adjustment ring 67 is fixedly connected to the docking rod 81, and the shielding piece 84 slides at the air vent 2, and the opening of the air vent 2 is shielded by the shielding piece 84 to adjust the ventilation area of ​​the sample drawer 3 below the air vent 2.

[0042] like Figure 5As shown, a cavity is provided inside the collection box 1 , the slide plate 82 slides in the cavity of the collection box 1 , the end of the docking rod 81 extends into the cavity, and the shape of the shielding sheet 84 when fully unfolded is the same as the opening shape of the air vent 2 .

[0043] When the wind is strong, the adjusting ring 67 moves to the right and uses the docking rod 81 to pull the shielding piece 84, so that the shielding piece 84 is unfolded to reduce the ventilation area of ​​the air vent 2, that is, to reduce the ventilation area for collecting samples of wetland flora; when the wind is weak, the adjusting ring 67 moves to the left and uses the docking rod 81 to push the shielding piece 84, so that the shielding piece 84 is rolled up to increase the ventilation area of ​​the air vent 2, that is, to increase the ventilation area for collecting samples of wetland flora.

[0044] A branch plate 83 is fixedly installed on the side of the docking rod 81, and the docking rod 81 and the branch plate 83 form a fishbone structure. A reel 85 is rotatably connected to the inner wall of the collection box 1 and located at the air vent 2. The shielding sheet 84 is reeled on the reel 85, and a coil spring 86 is elastically connected between the reel 85 and the collection box 1. The shielding sheet 84 is reeled by the reel 85. When the adjustment ring 67 moves to the right to pull the shielding sheet 84 to unfold, the shielding sheet 84 moves to rotate the reel 85 and compress the coil spring 86. When the adjustment ring 67 moves to the left, the elastic force of the coil spring 86 resets the reel 85, and the shielding sheet 84 is reeled again.

[0045] In this embodiment, by converting wind force into centrifugal force, when the wind force is strong, the centrifugal block 64 moves away from the wind shaft 61, so that the adjustment ring 67 moves to the right, thereby unfolding the shielding sheet 84, reducing the ventilation area of ​​the air vent 2, that is, reducing the ventilation area for collecting samples of wetland flora. When the wind force is weak, the adjustment ring 67 moves to the left, thereby rolling up the shielding sheet 84, increasing the ventilation area of ​​the air vent 2, that is, increasing the ventilation area for collecting samples of wetland flora.

[0046] Example 2

[0047] Based on Example 1, this example proposes a wetland plant community diversity survey device, such as Figure 2 and Figure 6 As shown, a graded adjustment component 7 is provided at the shaft of the wind shaft 61, and the graded adjustment component 7 includes a sleeve 71, a return spring 72 and a guide groove 73. The adjustment ring 67 slides on the inner wall of the sleeve 71, and the return spring 72 is elastically connected between the side of the adjustment ring 67 and the sleeve 71. The inner wall of the sleeve 71 is provided with a guide groove 73, and the upper and lower sides of the adjustment ring 67 are provided with protrusions, and the protrusions of the adjustment ring 67 are embedded in the guide groove 73. The guide groove 73 guides the adjustment ring 67 to prevent it from rotating.

[0048] like Figure 6As shown, a plurality of protruding springs 74 are fixedly mounted on the inner wall of the sleeve 71, and a groove 75 is provided at the protruding part of the adjusting ring 67, and the springs 74 are engaged with the grooves 75. The design of the plurality of springs 74 allows the adjusting ring 67 to be adjusted in stages, and the grooves 75 on the adjusting ring 67 are engaged with the springs 74, so as to avoid the adjusting ring 67 from being constantly displaced and rubbed during the wind force change, thereby extending its service life.

[0049] A support plate 77 is fixedly installed on the top of the collection box 1, and the end of the wind shaft 61 is rotatably connected to the support plate 77, and a positioning rod 76 is fixedly installed between the support plate 77 and the sleeve 71. The height of the wind shaft 61 is supported by the support plate 77 and the fan 5, and the support plate 77 uses the positioning rod 76 to limit the position of the sleeve 71, so that the sleeve 71 and the adjustment ring 67 therein cannot rotate, so as to prevent the adjustment ring 67 from rotating and causing the docking rod 81 to break.

[0050] In this embodiment, the adjustment ring 67 is adjusted in stages through the design of multiple reeds 74. The groove 75 on the adjustment ring 67 is stuck on the reed 74, so as to fix the position of the adjustment ring 67. When the wind force changes, the adjustment ring 67 is detached from one of the reeds 74 and stuck on another reed 74, so as to avoid the wind force changing too fast and causing the adjustment ring 67 to continuously move and rub, thereby extending its service life.

[0051] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
