Description

Technical Field

[0001] This utility model relates to the field of insect and moth resistance evaluation technology, and in particular to an insect and moth resistance performance rating device. Background Technology

[0002] When conducting mothproofing performance rating tests on textiles, selected moth larvae need to be placed on control samples and test samples of known quality for 14 days. The mothproofing performance of each sample is comprehensively evaluated based on the mass loss, degree of damage, and survival rate of the larvae.

[0003] Since there are no standard reference objects in this standard, the evaluation of insect-proofing effect is carried out by the test personnel visually. It is divided into 1234 visible surface damage evaluation and ABCD insect-eaten hole evaluation. This method has a large subjective bias, and the test results vary greatly between different personnel, resulting in low accuracy. If it is necessary to train personnel with accurate vision, a lot of training and comparison learning time is required, and the training cycle for personnel is long.

[0004] In view of this, this application proposes a device for rating the performance of insect and borer prevention. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an insect-proof performance rating device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An insect-proof performance rating device includes an installation frame structure, an isolation structure installed within the installation frame structure, and a cleaning structure slidably connected within the isolation structure. The isolation structure includes a fixed isolation cover, a stabilizing ring installed on the lower side of the fixed isolation cover, a culture dish installed inside the stabilizing ring, and an isolation mesh installed inside the culture dish; The cleaning structure includes an outer ring connecting pipe that slides within a fixed isolation cover, an outer ring air blowing pipe arranged in a circumferential array connected to the outer ring connecting pipe, an inner ring connecting pipe connected to the outer ring connecting pipe, and an inner ring air blowing pipe arranged in a circumferential array installed on the inner ring connecting pipe.

[0007] As a further preferred embodiment of this technical solution, the mounting frame structure includes a base, on which symmetrically distributed support frames are mounted, and mounting rings are installed between the support frames. The fixed isolation cover is installed inside the mounting rings, and a mounting bracket is mounted on the base. A camera is mounted on the mounting bracket, and the lower end of the camera is in contact with the fixed isolation cover.

[0008] As a further preferred embodiment of this technical solution, the base is rotatably connected with symmetrically distributed fixing rods, and the fixing rods are threaded together with a sliding tray, which is installed inside the petri dish.

[0009] As a further preferred embodiment of this technical solution, the fixed isolation cover is provided with an observation slot, the camera is installed in the observation slot, the isolation net is higher than the bottom of the petri dish, and the evaluation sample is placed on the isolation net.

[0010] As a further preferred embodiment of this technical solution, a telescopic motor is mounted on the mounting bracket, a telescopic rod is mounted on the telescopic motor, an air pump is mounted on the telescopic rod, and a circumferentially arrayed array of air pipes is connected to the air pump, which is connected to an outer ring connecting pipe.

[0011] As a further preferred embodiment of this technical solution, the outer ring connecting pipe and the inner ring connecting pipe are connected to symmetrically distributed suction pipes, a connecting ring is installed between the outer ring connecting pipe and the inner ring connecting pipe, and the air pipe connected to the suction pipe is not connected to the air pipe connected to the outer ring blowing pipe and the inner ring blowing pipe.

[0012] This utility model has the following beneficial effects: This invention uses a camera to photograph and record the test samples that have been eaten by woodworms, and then compares the results of multiple groups of test samples. During the test, a telescopic motor drives an air pump to slide downwards, which in turn moves the ventilation tube synchronously. The air pump controls the outer and inner ring air pipes to blow air onto the test samples on the isolation net, so that the woodworms, woodworm excrement, molted skin and loose fibers on the test samples are placed vertically at the bottom of the culture dish to avoid affecting the subsequent weighing. At the same time, by collecting the woodworms in the culture dish, it is easy to observe the state of the woodworms. On the other hand, the air suction tube, inner ring air pipe and outer ring air pipe work together to suck flying woodworms into the air suction tube. After separating and fixing the isolation cover and the culture dish, the woodworms in the air suction tube are collected. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] This utility model provides a technical solution: such as Figure 1-5 As shown, an insect-proof performance rating device includes an installation frame structure 1, an isolation structure 2 installed inside the installation frame structure 1, and a cleaning structure 3 slidably connected inside the isolation structure 2. The isolation structure 2 includes a fixed isolation cover 21, a stabilizing ring 23 installed on the lower side of the fixed isolation cover 21, a petri dish 24 installed inside the stabilizing ring 23, and an isolation net 25 installed inside the petri dish 24. The cleaning structure 3 includes an outer ring connecting pipe 35 that slides inside the fixed isolation cover 21, an outer ring air blowing pipe 37 arranged in a circumferential array connected to the outer ring connecting pipe 35, an inner ring connecting pipe 36 connected to the outer ring connecting pipe 35, and an inner ring air blowing pipe 38 arranged in a circumferential array connected to the inner ring connecting pipe 36.

[0017] It should be noted that before testing the insect-proof performance of textiles, multiple samples of appropriate size need to be cut from the textiles to be tested, and the samples are placed on the isolation net 25 in the culture dish 24. Then, the insects are placed on the test samples. After that, the culture dish 24 is placed in the stabilizing ring 23 and attached to the fixed isolation cover 21. Then, the device is placed in the dark for fourteen days.

[0018] Fourteen days later, the outer ring connecting pipe 35 and the inner ring connecting pipe 36 slide downwards, thereby driving the outer ring blowing pipe 37 and the inner ring blowing pipe 38 to slide synchronously until the outer ring connecting pipe 35 and the inner ring connecting pipe 36 slide to their limit positions. Then, the gas blown out through the outer ring blowing pipe 37 and the inner ring blowing pipe 38 is sprayed onto the upper surface of the test sample on the isolation net 25, blowing away the borers, borer excrement, molted skin and loose fibers from the test sample and letting them fall into the bottom of the culture dish 24 through the isolation net 25.

[0019] like Figure 2 and 3 As shown, the mounting frame structure 1 includes a base 11, on which symmetrically distributed support frames 12 are mounted, and mounting rings 13 are installed between the support frames 12. A fixed isolation cover 21 is installed inside the mounting rings 13. A mounting bracket 14 is mounted on the base 11, and a camera 15 is mounted on the mounting bracket 14. The lower end of the camera 15 is in contact with the fixed isolation cover 21. A symmetrically distributed fixing rod 17 is rotatably connected to the base 11, and a sliding tray 16 is threadedly connected to the fixing rod 17. The sliding tray 16 is installed inside the petri dish 24. An observation slot 22 is opened on the fixed isolation cover 21, and the camera 15 is installed inside the observation slot 22. An isolation net 25 is higher than the bottom of the petri dish 24, and a test sample is placed on the isolation net 25.

[0020] It should be noted that the camera 15, which is installed on the mounting bracket 14, is aimed at the observation slot 22 opened on the fixed isolation cover 21. The camera 15 continuously takes pictures of the test samples on the isolation net 25, recording the process of the test samples being eaten by insects, and at the same time recording the state of the test samples after being eaten. By comparing the state of multiple test samples after being eaten, the average value of the lost area of ​​the test samples after being eaten is obtained.

[0021] Meanwhile, by rotating 27, the distance between the culture dish 24 and the fixed isolation cover 21 is adjusted, thereby controlling the distance between the culture dish 24 and the fixed isolation cover 21, and thus adjusting the airtight state of the fixed isolation cover 21 and the culture dish 24, ensuring that insects will not crawl out of the culture dish 24 during the evaluation process.

[0022] like Figure 4 and 5 As shown, a telescopic motor 31 is mounted on the mounting bracket 14, a telescopic rod 32 is mounted on the telescopic motor 31, an air pump 33 is mounted on the telescopic rod 32, and a circumferentially arrayed air pipe 34 is connected to the air pump 33. The air pipe 34 is connected to the outer ring connecting pipe 35. The outer ring connecting pipe 35 and the inner ring connecting pipe 36 are connected to symmetrically distributed suction pipes 39. A connecting ring 310 is installed between the outer ring connecting pipe 35 and the inner ring connecting pipe 36. The air pipe 34 connected to the suction pipe 39 is not connected to the air pipe 34 connected to the outer ring blowing pipe 37 and the inner ring blowing pipe 38.

[0023] It should be noted that the ventilation pipes 34 with an included angle of 90 degrees are complementary and connected, and the ventilation pipes 34 with an included angle of 180 degrees are connected. The ventilation pipes 34 are driven to slide downward by the telescopic rod 32, so that the ventilation pipes 34 connected to the air pump 33 can input gas into the outer ring connecting pipe 35 and the inner ring connecting pipe 36. Then, the gas is sprayed onto the test sample on the isolation net 25 through the outer ring blowing pipe 37 and the inner ring blowing pipe 38, thereby blowing the woodworms, woodworm excrement, molted skin and loose fibers on the test sample on the isolation net 25 to the bottom of the petri dish 24.

[0024] Since some borers may molt within fourteen days, and new borers may grow wings, the air blown out by the outer ring air pipe 37 and the inner ring air pipe 38 alone cannot allow flying borers to enter the bottom of the culture dish 24. Therefore, the air pump 33 draws air from the suction pipe 39 into the ventilation pipe 34. At the same time, the outer ring air pipe 37 and the inner ring air pipe 38 continue to blow air. The air pump 33, the ventilation pipe 34 and the fixed isolation cover 21 and the culture dish 24 circulate the gas, thereby ensuring that flying borers enter the suction pipe 39.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
