Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figures 1 to 4, the utility model one simulation desertification experiment cabinet, comprises cabinet 2 and is connected to bellows 1 and the silt container 19 at described cabinet 2 two ends; Described bellows 1 top is provided with control knob, and described bellows 1 are provided with exhausting plate 7 with described cabinet 2 contact jaw; Described cabinet 2 comprises base plate 9 and is arranged on the breast board 10 on base plate 9, the space that described base plate 9 and described breast board 10 form is divided into desert belt 15, semidesert band 16 and non-desert belt 18 3 parts, and described semidesert band 16 and described non-desert belt 18 are provided with some detachable false trees 17; Husky groove 22 is provided with bottom described silt container 19.
Prioritization scheme 1, described control knob comprise calm button 3, weak wind button 4, apoplexy button 5 and high wind button 6, control inner fan provide simulation wind regime not of the same race by the control knob on bellows 1.Such as, press weak wind button 4 and provide weak wind wind regime, press apoplexy button 5 and provide medium sized wind regime, pressing 6, high wind button provides high strength to simulate wind regime, presses 3, calm button and does not provide wind regime.
Prioritization scheme 2, described exhausting plate 7 are provided with some air outlet openings 8, simulation wind regime is not directly will simulate wind in experiment cabinet, but by some air outlet openings 8 that exhausting plate 7 is arranged, wind-force is dispersed, eliminate wind concentration, to reach simulate effect true to nature.
Prioritization scheme 3, described breast board 10 are provided with side plate 11 and tailgate 13; Described side plate 11 is provided with side pore 12, described tailgate 13 is provided with the first air vent 14, described first air vent 14 opposite side pore 12 is less.Owing to being placed with the sand for simulating desertification in experiment cabinet, therefore breast board 10 is set on its base plate 9, simultaneously in order to prevent simulation wind regime from sand blowout being gone, breast board 10 is provided with the side plate of side gas sky 12 and the tailgate 13 with the first air vent 14, wherein the setting of side gas empty 12 and the first air vent 14 is to keep airflow, wherein the first air vent 14 is compared side gas sky 12 less is because simulation wind regime directly blows on tailgate 13, and on tailgate 13, the first air vent 14 of setting is less is to prevent simulation wind regime from sand blowout being gone.
Prioritization scheme 4, described silt container 19 side are provided with the second air vent 20, and described silt container 19 bottom outside is provided with floor 21.Silt container 19 is that have the small part grains of sand to be blown and arrange, the floor 21 arranged in its bottom outside strengthens its stability in order to prevent when high strength simulates wind regime.And be provided with the circulation that the second air vent 20 keeps air-flow simultaneously.
Prioritization scheme 5, described first air vent 14 do not line up with described second air vent 20.The reason that first air vent 14 and the second air vent 20 do not line up is because when high strength simulates wind regime, prevents the grains of sand from being blown out by secondary.Realize keeping classroom health not waste the target of resource when doing simulated experiment.
The utility model specific works principle and using method: wherein principle is adopt adjustable simulation wind regime to dry to the desert belt 15 of simulating, semidesert band 16 and non-desert belt 18, and can arrange false tree 17 on desert belt 15, semidesert band 16 and non-desert belt 18.Control knob now can be used to regulate different wind speed and make wind to the desert belt 15 being provided with false tree, semidesert band 16 and the non-desert belt 18 of simulating, observe the change of every part, distinguish the difference of planting trees at desert belt 15 and not planting trees, distinguish the difference of planting trees at semidesert band 16 and not planting trees, distinguish the difference of planting trees at non-desert belt 18 and not planting trees.Allow classmates in person observe and analyze the importance of planting trees.
Transparent breast board 10, side plate 11, tailgate 12 and base plate 9 that the utility model is arranged around base plate 9 form a casing with opening, and the hole ensureing airflow is set on side plate 11, tailgate 12, in order to prevent the grains of sand to be blown, add a silt container 19 with husky groove 22 at tailgate 12 place.Wherein the second air vent 20 and the first air vent 14 do not line up, and ensure again that the grains of sand can blow out.
The utility model is a kind of simulation desertification experiment cabinet; simulate the harm of desertification and plant the prevention of false tree to desertification; allow the whole process that observation of students desertification is formed; and understand that tree planting effectively can prevent the formation of desertification; the learning interest of student's natural sciences over the ground effectively can be improved by the utility model; and educate student and the moment will set up Green Homeland, protection home.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
