Problems solved by technology

In China, Zhou Qun and others also gave a centrifugal adhesion test platform based on high-speed image feedback in Volume 36 of Tongji University in 2008, "Ant Adhesion Test and ANSYS Analysis", but it can only test horizontal and vertical Climbing force in both directions
[0005] The Chinese patent with the publication number CN101482553 "A force measuring device and test method for measuring the adhesion between living organisms and objects" proposes a force measuring device and testing method for measuring the adhesion force between living organisms and objects using the principle of leverage , but the test method is complicated in sample preparation and cumbersome in experimental steps
Moreover, these three test devices can only test the adhesion of insects to rough surfaces at specific angles, and the test range is small
The above-mentioned patents are all different from the device and method of the present invention, and cannot be used for the measurement of insect climbing force

Embodiment 1

[0038] Such as figure 1 As shown, it is a perspective view of the measuring device used to measure the probability of insects climbing on rough surfaces. Its front view and side view are as follows figure 2 and image 3Shown, by placing the transparent case 1 of insect 13, climbing board 2, the transposition mechanism 3 that drives transparent case 1 to rotate, realize the vibrating mechanism 4 that transparent case 1 vibrates up and down, spring base 5, observe the position and position of insect 13 The digital camera device 6 in the climbing state is composed of a control and data processing system 7 for data collection and mechanism operation.

[0039] The spring base 5 is provided with a transparent box 1 and an indexing mechanism 3 connected with the transparent box 1 , and a climbing board 2 is arranged in the transparent box 1 . The transparent box 1 is made of transparent plexiglass, and its shape is a triangular prism. , The door 12 is equipped with a handle, whi...

Embodiment 2

[0051] Using the measuring device described in Example 1 for measuring the probability that insects can climb onto rough surfaces, taking flies as an example, using silica polishing paper with a particle size of 5 μm as the climbing board 2, and testing it when it is inverted when it is shaken and disturbed. The probability of crawling. The specific steps are:

[0052] (1) Turn on the indexing stepper motor 31 to drive the transparent box 1 to rotate to Figure 6a In the flat state shown, take the climbing board 2 to be tested, cut it into a size of 20cm×10cm, paste double-sided tape on the reverse side, then open the door 12, and stick the climbing board 2 on the bottom of the transparent box 1. Get 50 insects to be tested simultaneously, glue the wings of the flies together to make them lose their ability to fly, put them into the relatively rough surface of the climbing board 2, and close the door 12;

[0053] (2) Adjust the height of the camera frame 62 to below the ...

Embodiment 3

[0060] Using the measuring device described in Example 1 for measuring the crawling probability of insects on rough surfaces, taking ants as an example, test their crawling probability under vibration interference when they are inverted on climbing boards with different roughnesses. The specific steps are:

[0061] (1) Turn on the indexing stepper motor 31 to drive the transparent box 1 to rotate to Figure 6a In the flat state shown, take silica polishing paper with a particle size of 1 μm, 2 μm, 3 μm, 4 μm, and 5 μm, cut it into strips of 10cm×4cm, and arrange them in the form of strip climbing board A , as the climbing board 2, its reverse side is pasted with double-sided adhesive tape, then the door 12 is opened, and the climbing board 2 is stuck on the bottom surface of the transparent case 1. Get 50 insects to be tested simultaneously, put into the relatively rough surface in the climbing board 2, close the door 12;

[0062] (2) Adjust the height of the camera frame 62...

Abstract

The invention relates to a device for measuring the creeping probability of an insect on a rough surface. The device for measuring the creeping probability of the insect on the rough surface comprises a transparent box, a creeping plate, a displacement mechanism, a vibration mechanism, a spring base and a digital pick-up device. The testing method comprises the following steps of: I, opening the transparent box, sticking the creeping plate into the transparent box, putting the insect onto the creeping plate, and closing the transparent box; and II, driving the transparent box to rotate to a specified position through the displacement mechanism, controlling the transparent box to rotate back and forth to produce swinging interference, controlling the vibration mechanism to rotate to generate vibration interference, or performing swinging interference and vibration interference simultaneously, adjusting the shooting angle of the digital pick-up device, and observing the creeping probability and falling probability of the insect through the digital pick-up device. According to the device and the method, the creeping probability of the insect at different space positions and surfaces of different roughness can be measured.

Description

technical field [0001] The invention relates to a measuring device and method for the probability of insects being able to climb on a rough surface, and belongs to the field of measuring the climbing performance of living organisms and surfaces. Background technique [0002] In nature, people often see flies, ants, crickets and other insects crawling quickly on smooth surfaces, and even hang upside down from the ceiling. This peculiar natural phenomenon has aroused the interest of countless biologists, and they have conducted in-depth research on it. Studies have found that many insects have sticky pads of various shapes on their feet. These footpads are quick to release, and the traction generated by the footpads controls walking and running. Its mechanism shows amazing structural diversity and remarkable performance. The adhesion mechanism and friction characteristics between the crawling process and the contact surface are important branches of bionics. The research ...
