Description

Technical Field

[0001] The invention relates to the technical field of pine wood nematode disease detection, and in particular to a small-sized pine wood nematode disease rapid detection device which is easy to move. Background Art

[0002] As a devastating forest disease, pine wilt disease poses a serious threat to global forest resources. It spreads quickly and has a high mortality rate. Once it breaks out, it often causes large areas of pine trees to die quickly, causing huge losses to the ecological environment and forestry economy. Therefore, timely, accurate and efficient pine wilt disease detection is crucial for disease prevention and control. However, existing detection technologies and equipment face many challenges in outdoor applications, especially in terms of portability and refrigeration requirements.

[0003] When conducting pine wood nematode disease testing outdoors, traditional equipment is often bulky and heavy, making it difficult to carry and move. This not only limits the flexibility of testing work, but also increases the difficulty of field work. Especially in remote mountainous areas or areas with inconvenient transportation, the transportation and installation of equipment has become a major problem, seriously affecting the timeliness and coverage of disease monitoring.

[0004] In addition, the test kits used for pine wilt disease detection usually need to be refrigerated to maintain their activity and stability. This requirement further complicates outdoor testing. Traditional refrigeration methods, such as using ice packs or portable refrigerators, not only take up space, but also increase the power consumption of the equipment. In the field, the power supply is often unstable or difficult to obtain, which makes the operation and maintenance of refrigeration equipment a major challenge. At the same time, the energy consumption of refrigeration equipment also increases the cost of testing, limiting the continuity and extensiveness of testing work.

[0005] In summary, there is an urgent need for a small-scale rapid detection device for pine wood nematode disease that is easy to move and capable of long-term detection. Summary of the invention

[0006] The present invention aims to provide a small-sized pine wood nematode disease rapid detection device which is easy to move, thereby solving the problem that the existing pine wood nematode disease rapid detection device is not easy to move and operate outdoors.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a small-scale pine wood nematode disease rapid detection device that is easy to move comprises a back plate, two elastic straps are symmetrically arranged on one side of the back plate, and two interval-arranged slide grooves are opened on the other side of the back plate, a rack is slidably connected in any of the slide grooves, the rack is meshed with a driving gear rotatably connected to the back plate, and a guide rod is slidably connected in the other slide groove, the guide rod and the rack are both connected to the inner wall of the corresponding slide groove by a spring, a placement box is provided on the guide rod, and a downward driving assembly is provided on the placement box, and the downward driving assembly can drive the rack to move downward when the placement box moves downward, a battery and a cold storage box are provided in the placement box, a detection machine electrically connected to the battery is provided on the battery, a refrigerator electrically connected to the battery is provided in the cold storage box, and a limit assembly is provided between the detection machine and the cold storage box, and the limit assembly is used to keep the relative position of the detection machine and the cold storage box unchanged.

[0008] Furthermore, the downward driving assembly includes a connecting hook rotatably connected to the rack and a connecting rope matched with the connecting hook, both ends of the connecting rope are adhered to the placement box, and the end of the connecting hook is slidably connected to the surface of the placement box.

[0009] Through the above arrangement, when the inspector carries the device outdoors and moves with the device on his back, when the placement box moves downward, the placement box drives the rack to move downward with the help of the connection rope and the connection hook. After the rack moves, it drives the drive gear to rotate, thereby playing a role in unloading force, which can reduce the load force of the placement box on the inspector during the movement, reduce the fatigue strength caused by the inspector moving the device, and facilitate carrying the device. At the same time, when the placement box moves upward, the rack will move upward and reset under the action of the spring. At this time, although the rack will drive the drive gear to rotate, because the connection rope is separated from the connection hook and the connection force is also upward, the rotation of the drive gear will not produce resistance to the movement of the placement box, thereby not affecting the height of the placement box moving upward, which is conducive to maintaining the vibration amplitude of the inspector in the process of carrying the placement box, achieving load reduction while providing powerful conditions for subsequent kinetic energy conversion.

[0010] Furthermore, a snap-in hole is provided in the back plate, and the snap-in hole can be snapped and connected with the connecting hook.

[0011] Through the above arrangement, when detection is required, the stability of the placement box can be maintained by utilizing the cooperation between the connecting hook and the snap-in hole, thereby facilitating rapid detection of nematode disease.

[0012] Furthermore, the limiting assembly includes a fixed plate, which is arranged in the middle of the placement box, and an adjusting screw is threadedly connected to the fixed plate. Both ends of the adjusting screw are threadedly connected to adjusting screw tubes, and the two adjusting screw tubes are respectively located on both sides of the fixed plate, and each adjusting screw tube is connected to a baffle.

[0013] Through the above-mentioned arrangement, the detection machine and the refrigerated box can be confined in the placement box under the clamping action of the adjusting screw, the adjusting solenoid, the baffle and the inner wall of the placement box, thereby ensuring that the detection machine and the refrigerated box will not collide with the placement box during the movement of the device, thereby improving the reliability of subsequent detection work, and at the same time, active adjustment can be performed according to different models or sizes of detection machines and refrigerated boxes, thereby expanding the application scope of this solution.

[0014] Furthermore, the driving gear is provided with a rotating shaft, the rotating shaft is connected to a micro generator, and the micro generator is electrically connected to a battery.

[0015] Through the above arrangement, in the process of the placement box moving up and down, the rotation of the rotating shaft can be used to convert mechanical energy into electrical energy through the micro-generator, and then stored in the battery, which is beneficial to maintaining the battery life.

[0016] Furthermore, a solar panel is bolted to the upper surface of the placement box, and the solar panel is electrically connected to the battery.

[0017] Through the above settings, the solar panels can be used for power supplement when the sun is shining, which increases the detection endurance of the solution.

[0018] Furthermore, a receiving plate is rotatably connected to the back plate, and supporting holes perpendicular to each other are provided on the receiving plate and the back plate, and supporting plates are inserted into the two limiting holes.

[0019] Through the above arrangement, the receiving plate can receive the placement box, thereby preventing the placement box from suddenly falling during the up and down movement, thereby preventing the internal detection machine from being damaged, thereby improving the safety of the solution.

[0020] Compared with the prior art, this solution has the following beneficial effects:

[0021] 1. This solution provides a small and easy-to-move rapid pine nematode disease detection device. By being carried on the back, it can solve the problem that the existing rapid pine nematode disease detection device is not easy to move outdoors. At the same time, the test kit is refrigerated in a refrigerator to facilitate the detection, and the battery that provides power support can also be recharged in a variety of ways to ensure the continuity of the detection.

[0022] 2. In this solution, the placement box bears nearly 90% of the weight of the device. During the movement, the placement box descends through the spring, and the cooperation of the rack and the driving gear to achieve buffering and unloading, thereby effectively reducing the load of the placement box on the inspector during the movement, indirectly reducing the labor intensity of the inspector, which is conducive to long-term outdoor inspection operations and improves the practicality of the device.

[0033] A placement box 10 is fixedly connected to the guide rod 8, and a downward drive assembly is provided on the placement box 10. The downward drive assembly can drive the rack 4 to move downward when the placement box 10 moves downward. The downward drive assembly includes a connecting hook 11 rotatably connected to the rack 4 and a connecting rope 12 matched with the connecting hook 11. A groove 13 is provided at the upper end of the rack 4, and a first rotating shaft is rotatably connected in the groove 13. The end of the connecting hook 11 is covered on the first rotating shaft. A snap-in hole 14 is provided on the upper side of the back plate 1, and a fixed shaft 15 is provided in the snap-in hole 14. The fixed shaft 15 can be snapped and connected with the connecting hook 11. Both ends of the connecting rope 12 are adhered to the placement box 10, and the end of the connecting hook 11 is slidably connected to the surface of the placement box 10.

[0034] A battery 16 and a refrigerator 17 located above the battery 16 are provided at the bottom of the storage box 10, and a through slot 18 is provided at the rear side of the storage box 10 for the connection line between the battery 16 and the micro generator 6 to pass through. A detector 19 that can be electrically connected to the battery 16 is provided on the left side of the upper surface of the battery 16, and a refrigerator 20 is provided in the refrigerator 17. The refrigerator 20 is electrically connected to the battery 16. In this embodiment, the refrigerator 20 can be a cooling sheet. A limiter assembly is provided between the detector 19 and the refrigerator 17, and the limiter assembly is used to keep the relative position of the detector 19 and the refrigerator 17 unchanged. In this embodiment, the limiting assembly includes a fixing plate 21, which is adhered to the middle part of the placement box 10. A threaded hole is provided in the center of the fixing plate 21, in which an adjusting screw 22 is threadedly connected. Both ends of the adjusting screw 22 are threadedly connected with adjusting screws 23. The two adjusting screws 23 are respectively located on both sides of the fixing plate 21. Each adjusting screw 23 is rotatably connected to a baffle 24. Each baffle 24 is slidably connected in the space formed by the battery 16 and the inner wall of the placement box 10.

[0035] In this embodiment, a cover plate 25 is rotatably connected to the upper surface of the placement box 10 , and a solar panel 26 is bolted to the cover plate 25 . The solar panel 26 is electrically connected to the battery 16 .

[0036] Two spaced-apart circular tubes are integrally formed on the left and right sides of the bottom of the back panel 1, and a second rotating shaft 27 is rotatably connected in the two circular tubes. A receiving plate 28 is adhered to the second rotating shaft 27, and mutually perpendicular supporting holes are opened in the middle of the second rotating shaft 27 and the rear side of the back panel 1. A supporting plate 29 is inserted into the two limiting holes, and the support plate 29 is L-shaped. The supporting plate 29 can be used to rotate the receiving plate 28 to the bottom of the placement box 10, so as to avoid the placement box 10 accidentally falling to the ground and causing damage to the detection machine 19, thereby effectively ensuring the reliability of the device.

[0037] The working process of this embodiment is as follows:

[0038] When testing pine trees for pinewood nematode disease, the inspector carries the backboard 1 and the placement box 10 on his back through the elastic strap 2. When testing outdoors, since the testing site is often in a mountainous area or a forest, the inspector needs to go uphill or downhill frequently. During the movement of the inspector, the device can be easily carried and moved, thereby improving the flexibility and mobility of the test.

[0039] When the inspector moves the placement box 10 downward while walking, the placement box 10 slides into the connecting hook 11 on the rack 4 through the connecting rope 12, so that the connecting rope 12 applies the force generated by the downward movement of the placement box 10 to the connecting hook 11. At this time, the connecting hook 11 moves downward with the placement box 10 through the connecting rope 12. After the connecting hook 11 moves downward, it drives the rack 4 to move downward as well. At this time, the rack 4 drives the gear to rotate to achieve the buffering unloading force of the placement box 10. Since the weight of the placement box 10 accounts for nearly 90% of the weight of the entire device, and the downward movement of the placement box 10 will generate a large load on the inspector, at this time, the buffering unloading force of the spring 9 and the driving gear 5 can effectively reduce the load on the inspector, and can reduce the labor intensity of the inspector carrying or moving the device during the outdoor inspection process, so that the device can adapt to long-term outdoor operations.

[0040] At the same time, when the rack 4 drives the driving gear 5 to rotate, the driving gear 5 can convert mechanical energy into electrical energy through the micro-generator 6 after rotation, and store the electrical energy in the battery 16, which can extend the service life of the battery 16; and the battery 16 can also be charged through the solar panel 26 on the cover 25. With the help of multiple charging methods, the working time of the battery 16 can be extended, so that the device can extend the outdoor operation time.

[0041] When the storage box 10 moves upward, the spring 9 can reset the guide rod 8 and the slide plate through elastic force, and the connecting hook 11 begins to exert force on the connecting rope 12, which can assist the storage box 10 to move upward and reset. Although the rack 4 will still drive the driving gear 5 to rotate during the rising process, even if the rack 4 exerts force on the connecting rope 12 and the storage box 10 through the connecting hook 11, its function is to drive the storage box 10 upward to reset, so as not to affect the upward movement distance of the storage box 10 (that is, the rising height can be maintained as much as possible), so that when the storage box 10 descends, the rack 4 can generate appropriate mechanical kinetic energy for the driving gear 5 and the rotating shaft, thereby maintaining the generation and storage of electrical energy during outdoor movement, and further maintaining the working time of the battery 16.

[0042] In the long-term moving process, in order to prevent the placement box 10 from falling directly to the ground due to an accident and causing damage to the detection machine 19 in the placement box 10, the device can receive the accidentally dropped placement box 10 through the receiving plate 28, ensuring the reliability of the device. And when performing the detection, the back plate 1 and the receiving plate 28 are used for support, and the connection hook 11 is used to connect and cooperate with the fixed shaft 15, which is more conducive to placing the device on the ground for support and detection.

[0043] The above are only embodiments of the present invention, and the common knowledge such as the known specific structures and / or characteristics in the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
