A storage groove 117 is provided on one side of the body 12, and a display support structure 2 is arranged inside the storage groove 117. The display support structure 2 includes a protective shell 21, a motion card board 25 and two plug-in boards 215. The display 116 is fixedly installed inside the protective shell 21. An exhaust groove 1 26 and an exhaust groove 27 are provided on the top of the motion card board 25. A position control component is provided between the two plug-in boards 215 and the motion card board 25. A position fixing component is provided between the protective shell 21 and the motion card board 25. An automatic cleaning component is provided between the bottom of the protective shell 21 and the upper shell 12.

[0023] Specifically, a plurality of mounting grooves 13 are provided on both sides of the top of the lower shell 11 and on both sides of the bottom of the upper shell 12. A fixing plug plate 15 is provided inside the mounting groove 13 provided in the upper shell 12. When the upper shell 12 is installed on the top of the lower shell 11, the fixing plug plate 15 fixedly connected to the upper shell 12 is controlled to be inserted into the mounting groove 13 provided in the lower shell 11; and a threaded groove 14 is provided on one side of the mounting groove 13 provided in the lower shell 11. The threaded groove 14 is formed on the lower shell 11. The bolt 16 threadedly connected on the fixing plug plate 15 is rotated so that the bolt 16 partially rotates into the threaded groove 14. The bolt 16 is threadedly installed with the lower shell 11. 16 installs the fixed plug plate 15 and the lower shell 11 together to complete the installation of the upper shell 12 and the lower shell 11. The lower shell 11 and the upper shell 12 installed together by bolts 16 can be quickly installed and disassembled, which is convenient for operating and maintaining the magnet cabinet 17, the radio frequency cabinet 19 and the industrial computer 110 fixedly installed inside the lower shell 11, and the sampling tube 18 is installed on the top of the magnet cabinet 17, the feeding hole 3 opened on the upper shell 12 is arranged on the top of the sampling tube 18, the exhaust groove three 4 opened on the upper shell 12 is arranged on the top of one of the cooling fans 112, and the exhaust groove four 5 opened on the upper shell 12 is arranged on the top of the other cooling fan 112.

[0024] When it is necessary to use a spectrum generating device composed of the lower housing 11, the upper housing 12, the magnet cabinet 17, the radio frequency cabinet 19, the industrial computer 110, and the DDS 113, PSG 114 and ADC 115 inserted in the industrial computer 110, the specific steps of the spectrum processing method of the spectrum generating device are as follows: Step 1: Turn on the power supply for the atlas generating device. At this time, the display support structure 2 set inside the storage slot 117 opened on one side of the upper shell 12 is energized. At this time, the position control component set between the two plug-in boards 215 and the motion card board 25 works, and the double-axis pneumatic cylinder 219 in the position control component works and contracts. The two ends of the double-axis pneumatic cylinder 219 fixedly inserted at a position away from the protective shell 21 on one side of the motion card board 25 contract, and the connecting cross plates 218 fixedly installed at both ends of the double-axis pneumatic cylinder 219 move toward the motion card board 25 at the same time. The connecting cross plate 218 drives the fixedly connected plug-in board 215 to move, so that the plug-in board 215 leaves from the U-shaped frame 216 set on the outside, and the U-shaped frame 216 fixedly connected to the upper shell 12 loses the fixed limiting effect on the plug-in board 215. The motion card board 25 and the protective shell 21 fixed to the motion card board 25 lose the limit and can move. The display 116 fixedly connected inside the protective shell 21 loses the limit, and the display 116 enters the waiting state.

[0025] Step 2: The user holds the rubber handle 22 fixedly connected to one side of the protective shell 21, and pulls the rubber handle 22 arranged on the outside of the storage groove 117 to pull the protective shell 21 out of the storage groove 117, and two U-shaped frames 213 are arranged on the side of the protective shell 21 close to the plug-in board 215, and a limit baffle 214 is fixedly connected to the side of the U-shaped frame 213 away from the exhaust groove 27. The two U-shaped frames 213 fixedly connected to the upper shell 12 and the limit baffle 214 fixedly connected to one of the U-shaped frames 213 cannot move. Therefore, the moving protective shell 21 drives the moving card plate 25, the dual-axis pneumatic cylinder 219 and the two plug-in boards 215 to move. When the plug-in board 215 on the same side of the limit baffle 214 moves and is blocked by the limit baffle 214, the protective shell 21 completely leaves the storage groove 117, and the display 116 completely leaves the storage groove 117.

[0026] Step 3: Rotate the protective shell 21. Since the metal rod 29 in the fixing assembly is fixedly installed on one side of the protective shell 21, the metal rod 29 is inserted into the mounting cavity 28 formed on the moving card plate 25, and the outer rings of the two mounting bearings 210 fixedly sleeved on the outside of the metal rod 29 are fixedly connected to the moving card plate 25, the protective shell 21 forms a transmission relationship with the moving card plate 25 through the metal rod 29 and the two mounting bearings 210. Therefore, after the staff rotates the protective shell 21, the protective shell 21 drives the display 116 to rotate on one side of the moving card plate 25, and the electric The magnet 212 and the outer walls of multiple rubber sleeves 211 are fixedly connected to the motion card plate 25. There is a large friction between the multiple rubber sleeves 211 and the metal rod 29, which controls the rotation speed of the metal rod 29 and the protective shell 21, making it convenient for the staff to accurately adjust the rotation angle of the display 116. After the staff stops operating the protective shell 21 and the display 116, the display 116 and the protective shell 21 hover in place; therefore, the staff can rotate the display 116 to an angle that is convenient for viewing and then release it, and the display 116 will automatically hover in the corresponding position.

[0027] Step 4: Control the display support structure 2 to enter the working state through the display 116. At this time, the electromagnet 212 works. The working electromagnet 212 is adsorbed and fixed together with the iron metal rod 29 through magnetic force, so that the metal rod 29 is fixed and cannot rotate. Control the double-axis pneumatic cylinder 219 to work. The double-axis pneumatic cylinder 219 works to push the two plug-in plates 215 into the two U-shaped frames 213. Finally, the two plug-in plates 215 are against the two U-shaped frames 213 at the same time. With the cooperation of the two moving card plates 25 and the two U-shaped frames 213, the moving card plate 25 cannot move inside the storage slot 117, so that the relative position between the display 116 and the upper shell 12 is fixed.

[0028] Step 5: After the moving card plate 25 and the protective shell 21 move, the plug-in board 215 moves and the inside of the feed hole 3 loses its obstruction. At this time, the sampling tube 18 installed on the top of the magnet cabinet 17 is connected to the outside through the feeding hole 3. The staff can insert the bottom end of the glass tube containing the oil sample to be tested into the inside of the sampling tube 18 through the feeding hole 3, so that the glass tube containing the oil sample to be tested is partially inserted into the inside of the magnet cabinet 17, so that the oil sample to be tested enters the detection cavity inside the magnet cabinet 17.

[0029] Step 6: The display 116 is used to control the spectrum generating device to work. DDS113, PSG114 and ADC115 are inserted into the PCI slot of the industrial computer 110; DDS113 receives the parameters sent by the industrial computer 110 and generates a radio frequency signal, and PSG114 modulates the radio frequency signal into the required square wave, which is transmitted to the radio frequency power amplifier module inside the feed hole 3 connected to PSG114 for power amplification, and the radio frequency coil in the display support structure 2 excites the oil sample according to the amplified square wave to generate a nuclear magnetic resonance phenomenon. After receiving the nuclear magnetic resonance signal, the radio frequency coil in the display support structure 2 generates the nuclear magnetic resonance The signal is transmitted to the preamplifier in the feed hole 3 for power amplification. After amplification, the nuclear magnetic resonance signal is transmitted to ADC115 by the feed hole 3. ADC115 converts the nuclear magnetic resonance signal into a digital signal through the control of the pulse sequence in PSG114. The digital signal is sent to the industrial computer 110, and then the industrial computer 110 converts the digital signal into a transverse relaxation time spectrum. The transverse relaxation time spectrum is transmitted to the display 116 and compared with the transverse relaxation time spectrum of the authentic oil in the database of the display 116. The analysis result is displayed on the display 116, and the formation and analysis of the nuclear magnetic resonance spectrum can be completed.

[0030] Step 7: Pull out the glass tube of the oil sample to be tested, insert a new glass tube of the oil sample to be tested into the magnet cabinet 17, and repeat the above step 6.

[0031] Step 8: After the detection of multiple samples is completed, the electromagnet 212 is controlled to stop working through the display 116, and the user rotates the protective shell 21 to align the protective shell 21 with the storage slot 117, and controls the double-axis pneumatic cylinder 219 to contract. The double-axis pneumatic cylinder 219 drives the two plug-in plates 215 to leave the two U-shaped frames 213 and push the protective shell 21 into the storage slot 117; finally, the map generating device is powered off, at which time the double-axis pneumatic cylinder 219 is powered off and restored to the extended state, and the plug-in plate 215 moves back to the inside of the U-shaped frame 216 to limit the protective shell 21.

[0032] In summary, in the present application, the display 116 for analyzing the external spectrum and the spectrometer composed of the industrial computer 110, DDS113, PSG114, and ADC115 for generating the nuclear magnetic resonance spectrum together constitute a spectrum device. The display 116 and the spectrometer are electrically connected together, and the display 116 and the spectrometer are semi-separated, so that the operation and viewing of the display 116 will not affect the sealed protection structure of the spectrometer, thereby ensuring the safety of the spectrometer; and the movable display 116 is also sealed and stored in the storage slot 117 when not in use, thereby reducing losses caused by accidents during the movement of the spectrum generating equipment.

[0033] A cooling fan 112 is fixedly inserted on the top of the RF cabinet 19 and the industrial computer 110. After the protective shell 21 leaves the storage slot 117, the exhaust slot 1 26 moves to align with the exhaust slot 3 4. The exhaust slot 1 26 and the exhaust slot 3 4 form an exhaust channel connected to the outside world, and the exhaust slot 3 4 opened on the upper shell 12 is set on the top of one of the cooling fans 112. At this time, the top of the cooling fan 112 is connected to the outside world through the exhaust channel; After the protective shell 21 leaves the storage slot 117, the second exhaust slot 27 moves to align with the fourth exhaust slot 5. The second exhaust slot 27 and the fourth exhaust slot 5 form a heat dissipation channel connected to the outside world. The fourth exhaust slot 5 opened on the upper shell 12 is set on the top of another heat dissipation fan 112. The top of the heat dissipation fan 112 is connected to the outside world through the heat dissipation channel. Two cooling fans 112 are fixedly inserted on the RF cabinet 19 and the industrial computer 110 respectively. When the RF cabinet 19 and the industrial computer 110 are working, the two cooling fans 112 are controlled to extract air from the RF cabinet 19 and the industrial computer 110, and the hot air is discharged through the heat dissipation channel or the exhaust channel to cool down the inside of the RF cabinet 19 and the industrial computer 110, thereby improving the working stability of the RF cabinet 19 and the industrial computer 110; Four filters 111 are fixedly installed at the bottom of the outer side of the RF cabinet 19 and the industrial computer 110. The filter 111 filters the gas entering the RF cabinet 19 or the industrial computer 110 to prevent dust and impurities from entering the RF cabinet 19 or the industrial computer 110, and a plurality of pressure relief valves 6 are fixedly inserted at the bottom of the outer side of the lower shell 11. When the internal air pressure of the sealed box composed of the lower shell 11 and the upper shell 12 is reduced due to the exhaust of the cooling fan 112, the pressure relief valve 6 releases the pressure to allow outside air to enter the sealed interior. The cooling fan 112, the filter 111, the pressure relief valve 6 and other structures cooperate to form a simple air dispersion cycle, thereby completing the heat dissipation protection work for the RF cabinet 19 and the industrial computer 110.

[0034] In addition, such as Fig.10 As shown, when the protective shell 21 returns to the storage groove 117, the feed hole 3 is cut off by one of the plug-in plates 215, the exhaust groove three 4 is cut off by the moving card plate 25, and the exhaust groove four 5 is cut off by the protective shell 21, so that the lower shell 11 and the upper shell 12 are restored to a sealed state.

[0035] In addition, such as Fig.12 As shown, two supporting round rods 217 are inserted on the plug-in board 215, and the supporting round rods 217 are fixedly connected to the moving card plate 25. The two supporting round rods 217 support and limit the plug-in board 215 so that the plug-in board 215 can only move horizontally, thereby ensuring stable cooperation between the plug-in board 215 and the U-shaped frame 216.

[0036] In addition, such as Figure 8 and Fig. 9As shown, a rubber pad 220 is provided at the bottom of one end of the storage slot 117 away from the plug board 215. The rubber pad 220 is fixedly mounted on the upper shell 12. The rubber pad 220 applies a certain friction force to the protective shell 21 to ensure that the protective shell 21 is sealed inside the storage slot 117, thereby improving the safety of the sealed storage of the display 116.

[0037] In addition, such as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the storage tank 225 in the automatic cleaning component is formed on the upper shell 12 and is connected to the inside of the storage tank 117. A scraper 224 is arranged on one side of the top of the waste box 226 inserted in the storage tank 225. The scraper 224 is fixedly connected to the upper shell 12, and a support shaft 222 is arranged on the side of the scraper 224 away from the waste box 226. A sponge sleeve 221 and two one-way bearings 223 are provided on the outer fixed sleeve of the support shaft 222. The outer rings of the two one-way bearings 223 distributed at both ends of the support shaft 222 are fixedly connected to the upper shell 12, and the one-way bearings 223 can only rotate in one direction.

[0038] When the protective shell 21 drives the display 116 to leave the storage slot 117, the display 116 applies a rotational force to the rubber sleeve 211 and the support shaft 222. At this time, the rotation direction of the support shaft 222 is the self-locking direction of the one-way bearing 223, so the rubber sponge sleeve 221 cannot rotate to clean the display 116. When the protective shell 21 and the display 116 move toward the storage groove 117, the display 116 applies a rotational force to the rubber sleeve 211 and the support shaft 222. At this time, the force rotation direction of the support shaft 222 is the rotation direction of the outer ring of the one-way bearing 223. At this time, the rubber sleeve 211 rotates and is cleaned by the scraper 224. The inclined scraper 224 guides the impurities into the waste box 226 inside the storage groove 225. The force generated by the display 116 leaving the storage groove 117 and entering the storage groove 117 is used to complete the cleaning of the display 116 and the sponge sleeve 221, thereby ensuring that the display 116 is clean and convenient for the staff to watch the display 116.

[0039] An ear plate 227 is fixedly connected to one end of the waste box 226. The staff hooks the hollow ear plate 227 with a hook and pulls the waste box 226, which is interference fit with the upper shell 12, out of the storage tank 225 to clean the impurities inside the waste box 226.
