Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] The following are preferred embodiments of the present invention.

[0031] Example: Figure 1-Figure 3As shown, the scheme of this embodiment provides a biological woodlice experimental teaching equipment, the basic structure design of the equipment includes an experimental box 1, the wall panels of the experimental box 1 are all made of opaque material, two parallel partitions 2 are installed in the experimental box 1, the two partitions 2 divide the experimental box 1 into a first experimental chamber 3, a second experimental chamber 4 and a third experimental chamber 5, the second experimental chamber 4 is mainly used to place woodlice to be tested, the first experimental chamber 3 and the third experimental chamber 5 have exactly the same structural dimensions, and are symmetrically arranged compared to the second experimental chamber 4, as a control chamber, for conducting experiments on woodlice in a suitable environment; the two partitions 2 are both provided with channels 6, and the second experimental chamber 4 is connected to the first experimental chamber 3 and the third experimental chamber 5 respectively through the channels 6; the tops of the first experimental chamber 3 and the third experimental chamber 5 are both installed with covers 7, and the covers 7 are also made of opaque materials.

[0032] In the solution of this embodiment, the bottom plate of the second experimental chamber 4 is higher than the bottom plates of the first experimental chamber 3 and the second experimental chamber 4, and the two channels 6 are close to the bottom plate of the second experimental chamber 4. Before the experiment, the soil is placed in the first experimental chamber 3 and the second experimental chamber 4, and the thickness of the placement is based on the level of the bottom plate of the second experimental chamber 4, which is more conducive to the woodlice to move to suitable soil.

[0033] In the scheme of this embodiment, baffles 8 are slidably embedded in both partitions 2 to open or close the channel 6. Before the experiment, the channel 6 is closed by the baffles 8, and the woodlice are uniformly placed in the second experimental chamber 4. At the beginning of the experiment, the channel 6 is directly opened, and the woodlice will spontaneously move to a suitable environment, so that the experimental data is more comparable; after a period of time, when data statistics are required, the channel 6 is closed by the baffles 8, and the number of woodlice in each experimental chamber is counted. The woodlice in each experimental chamber will not run to other experimental chambers due to human fright, affecting the accuracy of the experiment. At the same time, the soil in the first experimental chamber 3 and the second experimental chamber 4 will not enter the second experimental chamber 4, blocking the channel 6 and affecting the secondary experiment.

[0034] In the scheme of this embodiment, filter screens 9 are installed in the first experimental chamber 3 and the second experimental chamber 4, and handles 10 are provided at both ends of the filter screens 9. The aperture of the filter screen 9 is smaller than the size of the woodlice, but can leak the soil. When collecting statistics, it is only necessary to lift the filter screen 9, shake it slightly, and let the soil fall. The woodlice are completely left in the filter screen 9, and the number is clear at a glance. At the same time, it is also more conducive to collecting woodlice for secondary experiments.

[0035] In the solution of this embodiment, a humidity sensor 11 near the bottom is installed in both the first experimental chamber 3 and the second experimental chamber 4. The humidity of the experimental environment is accurately controlled by the humidity sensor 11 to detect the adaptability of pillbugs to different humidity.

[0036] In the scheme of this embodiment, a water tank 12 is provided on one side of the experimental box 1, and a water injection port 13, two water pumps 14 and a condenser 15 are provided on the top of the water tank 12. The two water pumps 14 are connected to the bottom of the water tank 12 by pipes, and the condenser 15 is connected to the water tank 12 by pipes. The condenser 15 is fixedly installed on the top of the water tank 12 through a base 16, and the condenser 15 is provided with a return pipe 17. The water tank 12 can provide a water source for humidity regulation in the experimental box 1, and can also provide a return collection container for moisture when drying the soil. A movable spray pipe 18 is installed in the first experimental chamber 3 and the second experimental chamber 4. The spray pipe 18 is provided with a plurality of spray ports 19 facing the bottom. The first experimental chamber 3 and the second experimental chamber 4 are provided with a notch 20 for the spray pipe 18 to move. After the spray pipe 18 passes through the notch 20, it is connected to the water inlet pipe 21, and the water inlet pipe 21 is connected to the water pump 14. The water in the water tank 12 can be transported to the spray pipe 18 by the water pump 14 and sprayed onto the soil, thereby increasing the soil moisture.

[0037] In the scheme of this embodiment, the outer wall of the experimental box 1 is connected with two transmission screws 22 by bearings, and the two transmission screws 22 are respectively arranged parallel to the two notches 20. One end of the two transmission screws 22 is connected to the motor 23, and the motor 23 is fixedly connected to the experimental box 1. The two screws are threadedly connected to the transmission block 24, and the two spray pipes 18 are respectively fixedly connected to the two transmission blocks 24. The spray pipe 18 is set to be movable through the motor 23 and the screw drive, which is more conducive to uniformly humidifying the soil.

[0038] In the solution of this embodiment, a drying lamp 25 is provided in the cover body 7. The drying lamp 25 can dry the soil to reduce the soil moisture.

[0039] In the solution of this embodiment, a steam outlet 26 is provided on the top of the cover body 7, and the steam outlet 26 is connected to a wind pump 27, and the wind pump 27 is connected to a steam pipe 28, and the steam pipe 28 is provided with a joint 29, and the steam pipe 28 is detachably connected to the return pipe 17 through the joint 29. Under the baking lamp 25, the water will turn into steam. If it is directly discharged, it will not only pollute the environment, but also cause a waste of water resources. By setting the wind pump 27, the steam is uniformly extracted from the steam outlet 26 and enters the condenser 15 through the steam pipe 28 for condensation, and then flows back to the water tank 12 for collection.

[0040] Working principle:

[0041] Experiment 1: In a completely bright environment, woodlice are more suitable for living in a dry or humid environment.

[0042] The experimental operation principle is as follows:

[0043] Step 1: Lay dry and wet soil in the first experimental chamber 3 and the third experimental chamber 5 respectively, and do not cover the two covers 7; place a number of woodlice to be tested in the second experimental chamber 4;

[0044] Step 2: Move the two baffles 8 upward, open the passage 6, and wait for the woodlice in the second experimental chamber 4 to completely leave;

[0045] Step 3: Move the baffle 8 downward and close the channel 6;

[0046] Step 4: Lift the filter 9 upwards using the handle 10 to filter out the soil during the lifting process, and record the number of woodlice in the first experimental chamber 3 and the third experimental chamber 5.

[0047] Experiment 2: In a completely dark environment, woodlice are more suitable for living in a dry or humid environment.

[0048] On the basis of the “first group”, both covers 7 were closed, and the number of woodlice in the first experimental chamber 3 and the third experimental chamber 5 after the experiment was recorded.

[0049] Based on the results of Experiments 1 and 2, we can determine whether woodlice are suitable for living in a dry or humid environment.

[0050] On the basis of Experiments 1 and 2, the humidity comparison between the first experimental chamber 3 and the third experimental chamber 5 can be continuously changed to detect the most suitable environmental humidity value for the survival of woodlice.

[0051] Experiment 3: Experiment on the phototaxis of pillbugs.

[0052] Ensure that the humidity values ​​of the first experimental chamber 3 and the third experimental chamber 5 are the same, only cover any one of the covers 7 of the first experimental chamber 3 and the third experimental chamber 5, and observe the number of woodlice in the first experimental chamber 3 and the third experimental chamber 5. Thus, the phototropism of woodlice can be determined.

[0053] Through the above-mentioned embodiments of the present invention, compared with the prior art, the experimental teaching equipment of the present invention combines the survival needs of woodlice during use, which is convenient for woodlice in the experiment to choose a suitable living environment for themselves. The equipment has a simple and ingenious structural design and is easy to operate. It is convenient for observing woodlice in the experiment and will not cause harm to woodlice during the experiment, so that the experimental objects can be reused.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
