Description

Technical Field

[0001] The present invention relates to the field of cross-border animal-derived food, and in particular to an efficient pretreatment device for detecting cross-border animal-derived food. Background Art

[0002] The on-site intelligent detection technology at food ports is insufficient, with low accuracy, and there is a lack of mobile identification and detection technology and equipment, making it difficult to meet the actual needs of rapid food safety monitoring and efficient customs clearance. Research is being conducted on rapid and accurate detection technologies for harmful factors in cross-border bulk agricultural products based on Raman-enhanced spectroscopy and hyperspectral imaging. Port-site intelligent detection equipment such as portable Raman spectrometers and hyperspectral imaging are being developed. Integrated development of remotely controlled on-site inspection equipment equipped with detection equipment is being conducted to improve the intelligence level of cross-border food safety risk substance detection. A variety of dispersed detection technologies are being systematically integrated to develop a modular and intelligent technology system for rapid identification and accurate detection of imported food safety, providing technical support for achieving cross-border food safety prevention and control governance capabilities and modernization of the governance system.

[0003] Although portable Raman spectrometers are easy to carry, they have a compact size, squeezing a large number of electrical components into a small housing. This affects the heat dissipation of the electrical components. During normal use, the heat dissipation holes in the housing can dissipate heat, but under high load conditions, poor heat dissipation is likely to occur, leading to heat accumulation and accelerated damage to the electrical components.

[0017] 2. By setting up a buffer mechanism, the buffer mechanism is composed of springs of different specifications, each spring has its own elastic coefficient. Therefore, when the Raman spectrometer body falls from different heights, the impact force it receives will be buffered by corresponding springs. This is different from the existing springs with the same coefficient. When the pressure exceeds the elastic coefficient of the spring, the spring will no longer play a buffering role. When the pressure is too small, the pressure cannot trigger the elastic buffering of the spring. The present invention uses a multi-level spring setting to cover different pressures, so that the Raman spectrometer body can best trigger the spring to play a buffering and protective role under different pressures.

[0018] 3. By providing buckles on the protective box, the user can be guided to the correct holding posture. Only when the user holds the Raman spectrometer correctly can the telescopic empty plate be retracted to expose the display screen on the Raman spectrometer body for use. When the Raman spectrometer body falls off from the holder's hand, the telescopic empty plate will return to its original shape to protect the screen of the Raman spectrometer body and avoid damage.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0033] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] like Figure 1-3 、 Figure 8 As shown, an efficient pretreatment device for detecting cross-border animal-derived food includes a Raman spectrometer body 1, a hollow heat sink 13 is fixedly connected to the bottom of the Raman spectrometer body 1, a heat conducting base 12 is provided inside the hollow heat sink 13, the heat conducting base 12 extends into the interior of the Raman spectrometer body 1 and is fixedly connected to the Raman spectrometer body 1, a first heat dissipation fin 37 is fixedly connected to the heat conducting base 12, the first heat dissipation fin 37 is in the form of a strip, and the first heat dissipation fin 37 is provided with four rounded edges on its four sides, the first heat dissipation fin 37 includes a first fin group 38 and a second fin group 39, the first fin group 38 and the second fin group 39 respectively include a plurality of first heat dissipation fins 37 in a rectangular array, the first fin group 38 and the second fin group 39 are alternately arranged, and a heat dissipation mechanism is fixedly connected to the bottom of the hollow heat sink 13;

[0036] The heat dissipation mechanism is used to accelerate the flow of hot and cold air between the heat dissipation fins;

[0037] A protective mechanism is fixedly connected to the Raman spectrometer body 1, and the protective mechanism is used to regulate the user's holding method and protect the Raman spectrometer body 1;

[0038] The heat dissipation mechanism includes a mounting frame 14, a mounting tube 17 is provided inside the mounting frame 14, and the mounting tube 17 is connected to the mounting frame 14 through a plurality of fixing rods 16. A dual-axis motor is provided inside the mounting tube 17, and the power output shaft of the dual-axis motor extends to the outside of the mounting tube 17. The power output shaft at the top of the dual-axis motor is fixedly connected to the fan blade 15, and the power output shaft at the bottom of the dual-axis motor is connected to the toggle assembly;

[0039] The toggle assembly includes an exhaust box 18, a rotating shaft is provided on the exhaust box 18, the rotating shaft is rotatably connected to the exhaust box 18, a plurality of exhaust holes 19 are provided on the exhaust box 18, the exhaust holes 19 are connected to the hollow heat dissipation box 13, the rotating shaft is fixedly connected to the power output shaft of the dual-axis motor, the exhaust box 18 is fixedly connected to the hollow heat dissipation box 13, a cam 22 is provided inside the exhaust box 18, the cam 22 is fixedly connected to the rotating shaft, a piston column 20 is slidably connected to the exhaust box 18, one end of the piston column 20 is fixedly connected to the cam 21, and the other end of the piston column 20 is connected to the exhaust box 18 through a fifth spring 34;

[0040] When the Raman spectrometer body 1 runs at high speed, the heat generated is conducted through the heat-conducting base 12, so that most of the generated heat is accumulated on the first heat dissipation fins 37. When the dual-axis motor drives the fan blades 15 to rotate, the fan blades 15 blow air, and the blown air crosses and flows through the gaps between the longitudinally and transversely arranged first heat dissipation fins 37, so that the cold air and the hot air between the first heat dissipation fins 37 can be quickly exchanged, so that the heat accumulated on the first heat dissipation fins 37 can be quickly dissipated upwards.

[0041] Moreover, since the corners of the four sides are rounded, hot air can flow smoothly, and the gaps formed between the first heat dissipation fins 37 can help the hot air dissipate into the environment more quickly, thereby achieving a rapid heat dissipation effect;

[0042] When the shaft motor drives the fan blades 15 to rotate, it also drives the cam 22 to rotate. The rotation of the cam 22 will squeeze the protruding rod 21, so that the protruding rod 21 drives the piston column 20 to move. When the piston column 20 loses the squeezing of the cam 22, it will also be affected by the sixth spring 10 and return to its original position, causing the piston column 20 to continuously move left and right. In this way, the piston column 20 can squeeze and extract air, which can further accelerate the heat dissipation of the first heat dissipation fin 37.

[0043] Example 2:

[0044] like Figure 9-10 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is:

[0045] The first heat dissipation fin 37 can be replaced with the second heat dissipation fin 40 or the third heat dissipation fin 41;

[0046] The second heat dissipation fin 40 is strip-shaped, and the third heat dissipation fin 41 is trapezoidal. The second heat dissipation fin 40 forms a first longitudinal channel 402 for passing through by the first curved piece 401, which can increase the heat dissipation area of the second heat dissipation fin 40 and the air flow path, thereby improving the heat dissipation effect.

[0047] The third heat dissipating fin 41 forms a second longitudinal channel 412 for passage through the second bent piece 411 , which can increase the heat dissipation area of the third heat dissipating fin 41 and the airflow path, thereby improving the heat dissipation effect.

[0048] Example 3:

[0049] like Figure 11-12 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is:

[0050] The first heat dissipation fin 37 can be replaced with the fourth heat dissipation fin 42 or the fifth heat dissipation fin 43;

[0051] The fourth heat dissipation fins 42 are formed by the first arc-shaped pieces 421 and are provided with first grooves 422 on the tops thereof. This can increase the downward blowing area of the fan blades 15, so that the blown air has more channels and helps the hot air to dissipate quickly.

[0052] The fifth heat dissipation fin 43 is formed by the second arc-shaped piece 431, and a second groove 432 is provided on the top of each fin. This can increase the area of the fan blade 15 blowing air downward, so that the blown air can have more channels, helping the hot air to dissipate quickly.

[0053] Example 4:

[0054] like Figure 5-7As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: the protective mechanism includes a plurality of telescopic empty plates 4 and a protective box 2, the protective box 2 is fixedly connected to the Raman spectrometer body 1, and the plurality of telescopic empty plates 4 are slidably connected. The left and right sides of the telescopic empty plates 4 are respectively fixedly connected with a blocking plate 3 and a first magnetic plate 11, and the blocking plate 3 and the first magnetic plate 11 are connected by a plurality of sixth springs 10. The bottom of the telescopic empty plate 4 is fixedly connected with a sliding rod, the sliding rod passes through the protective box 2 and is slidably connected to the protective box 2, the bottom end of the sliding rod is fixedly connected with a buffer mechanism, the bottom of the buffer mechanism is fixedly connected with a partition 9, and the partition 9 is fixedly connected to the protective box 2;

[0055] The protective box 2 is fixedly connected to the inside of the protective box 2, and a sliding column 32 is provided on the fixed box 28. The sliding column 32 is slidably connected to the fixed box 28 and the protective box 2. The sliding column 32 is connected to the Raman spectrometer body 1 through a fourth spring 29. A rack 31 is fixedly connected to the bottom of the sliding column 32, and a gear 30 is meshed on the rack 31. A worm 8 is provided on the gear 30, and the worm 8 is fixedly connected to the gear 30. The worm 8 passes through the fixed box 28 and is rotatably connected to the fixed box 28. A worm wheel 6 is meshed on the worm 8, and a first screw 7 is fixedly connected to the worm wheel 6. The first screw 7 is rotatably connected to the protective box 2. A threaded block 5 is threadedly connected to the first screw 7. The threaded block 5 is slidably connected to the protective box 2. A second magnetic plate 35 is fixedly connected to the top of the threaded block 5, and the second magnetic plate 35 is magnetically attracted to the first magnetic plate 11;

[0056] The sliding column 32 is fixedly connected to the pressure plate 27, and the first magnetic plate 11 is fixedly connected to the protection plate 36;

[0057] When the user needs to use the Raman spectrometer body 1, he can place his fingers inside the opening on the protective box 2 and grip it. Since gripping will apply pressure, the pressure acts on the pressure plate 27, causing the pressure plate 27 to drive the sliding column 32 and the rack 31 to move, and the rack 31 drives the gear 30 to rotate, and the gear 30 drives the worm 8 to rotate, and the worm 8 drives the worm wheel 6 to rotate, and the worm wheel 6 drives the first screw 7 to rotate, and the first screw 7 will cause the threaded block 5 to move upward, and the threaded block 5 drives the second magnetic plate 35 to move upward, so that the second magnetic plate 35 moves out of the protective box 2. Since the second magnetic plate 35 is magnetically attracted to the first magnetic plate 11, when the second magnetic plate 35 moves out of the installation box and is located at the telescopic empty plate 4, it will attract the first magnetic plate 11, causing the telescopic empty plate 4 to shrink, exposing the display screen on the Raman spectrometer body 1, which is convenient for use;

[0058] And when the Raman spectrometer body 1 falls off, the sliding column 32 will return to its original position under the action of the fourth spring 29, so that the second magnetic plate 35 will also return to its original position. Without the function of the second magnetic plate 35, the first magnetic plate 11 will return to its original position under the action of the sixth spring 10 to protect the display screen of the Raman spectrometer body 1 and avoid damage due to falling.

[0059] Example 5:

[0060] like Figure 4 As shown, while other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that the buffer mechanism includes a second spring 25, the top and bottom of the second spring 25 are fixedly connected to the first spring 24 and the third spring 26 respectively, and the first spring 24 and the third spring 26 are fixedly connected to the sides facing away from each other with a mounting plate 23, and the two mounting plates 23 are fixedly connected to the partition plate 9 and the slide rod respectively;

[0061] When the Raman spectrometer body 1 falls and one side of the display screen hits the ground, the impact force will act on the telescopic empty plate 4, and the telescopic empty plate 4 will squeeze the first spring 24, the second spring 25, and the third spring 26 under the impact force;

[0062] Since the spring coefficients of the first spring 24, the second spring 25 and the third spring 26 are different, the impacts they can withstand are different, and thus they are suitable for drop impacts of different heights.

[0063] When the height is low and the impact force is small, the impact force can only act on the first spring 24 and cannot act on the second spring 25. The first spring 24 has a small elastic coefficient and can play a buffering role to the greatest extent, avoiding the phenomenon that the impact force is too small to trigger the spring buffering effect.

[0064] The same is true when the object is dropped from a high height. The impact force is too great, which directly impacts and squeezes the first spring 24 and breaks through the elastic coefficient of the first spring 24, acting on the second spring 25, so that the second spring 25 plays a buffering role.

[0065] It is effectively different from traditional fixed springs, which only have a fixed spring coefficient and cannot provide better cushioning over a wider range.

[0066] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
