[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example: Figure 1-Figure 13As shown, the present invention provides a technical solution of a maintenance and detection instrument for a nuclear magnetic resonance coil, comprising a nuclear magnetic resonance coil maintenance and detection device 1 and a power socket 4 installed on one side of the nuclear magnetic resonance coil maintenance and detection device 1, the nuclear magnetic resonance coil maintenance and detection device 1 comprises an installation box 11, a vector network analysis module 12, a multi-channel radio frequency signal multiplexer 13, a low-noise preamplifier detection module 14, a multi-channel signal acquisition and recording module 15 and a nuclear magnetic resonance coil port 16, an outward movement channel 18 is opened on one side of the installation box 11, a sealing frame 17 is arranged inside the outward movement channel 18, the sealing frame 17 is fixedly connected to the nuclear magnetic resonance coil port 16, and the sealing A nuclear magnetic resonance line support structure 2 is installed between the frame 17 and the installation box 11, and the nuclear magnetic resonance line support structure 2 includes a transmission frame 21 and a pneumatic telescopic rod 24. A combination panel 2 110 is fixedly installed on one side of the transmission frame 21, and an operation channel 111 is opened on one side of the combination panel 2 110. The transmission frame 1 21 is fixedly connected to two transmission frames 3 23, and the tops of the two transmission frames 3 23 are both provided with limiting components. An external structure 3 is arranged between the two transmission frames 3 23 and the installation box 11, and the external structure 3 includes a handle 1 32, two wire tubes 33 fixedly connected on both sides of the handle 1 32, and a pull wire 34 passing through the wire tube 33.

[0036] Specifically, the vector network analysis module 12, the multi-channel RF signal multiplexer 13, the low-noise preamplifier detection module 14, and the multi-channel signal acquisition and recording module 15 are all fixedly installed inside the installation box 11, and the nuclear magnetic resonance coil port 16 can slide inside the installation box 11. An outward movement channel 18 is opened on one side of the installation box 11. The sealing frame 17 arranged inside the outward movement channel 18 is fixedly connected to the nuclear magnetic resonance coil port 16. When the nuclear magnetic resonance coil repair detection device 1 is not working, the sealing frame 17 cooperates with the installation box 11 to seal and store the nuclear magnetic resonance coil port 16. At this time, the two sides of the installation box 11 are fixed. The sealing cover composed of two fixedly installed combination panels 19, a combination panel 2 110 arranged between the two combination panels 19, and a combination panel 3 112 arranged inside the operation channel 111 opened on the combination panel 2 110 seals the top of the installation box 11, so that the vector network analysis module 12, the multi-channel RF signal multiplexer 13, the low-noise preamplifier detection module 14, the multi-channel signal acquisition and recording module 15, and the nuclear magnetic resonance coil port 16 are sealed and protected by the sealing cover, which facilitates the movement of the nuclear magnetic resonance coil repair detection equipment 1 and ensures the convenience of using the nuclear magnetic resonance coil repair detection equipment 1.

[0037] And the combination panel three 112 is fixedly connected with the adjacent combination panel one 19, and the combination panel three 112 cannot move inside the installation box 11, and a reserved channel one 113 is opened on one side of the combination panel two 110, and the reserved channel one 113 is connected with the operation channel 111. The setting of the combination panel three 112 will not affect the movement of the combination panel two 110, and one end of the combination panel two 110 passes through the installation box 11 and extends to the outside of the installation box 11, so that the combination panel two 110 can slide on the installation box 11.

[0038] When the power socket 4 installed on one side of the nuclear magnetic resonance coil repair and detection device 1 is connected to the power supply, the nuclear magnetic resonance coil repair and detection device 1 enters the working state, and the pneumatic telescopic rod 24 fixedly inserted on the side of the combined plate 19 away from the operation channel 111 works and extends. Since a reserved channel 25 is opened on the outside of the installation box 11, the extended end of the pneumatic telescopic rod 24 passes through the reserved channel 25 and is fixedly connected to the transmission frame 1 21. Therefore, the working pneumatic telescopic rod 24 pushes the transmission frame 1 21 to move, so that the transmission frame 1 21 drives the fixedly connected combined plate 110 to move toward the outside of the installation box 11;

[0039] There are two transmission frames 22 fixedly connected between the transmission frame 1 21 and the sealing frame 17 arranged on the outside of the installation box 11, and the sealing frame 17 is fixedly connected to the nuclear magnetic resonance coil port 16, so the transmission frame 1 21 drives the nuclear magnetic resonance coil port 16 to move through the transmission frame 2 22 and the sealing frame 17, so that the nuclear magnetic resonance coil port 16 passes through the outward movement channel 18 and leaves the inside of the installation box 11, the nuclear magnetic resonance coil port 16 moves synchronously with the combination plate 2 110, and the relative position between the operating channel 111 and the nuclear magnetic resonance coil port 16 arranged on the top of the nuclear magnetic resonance coil port 16 remains unchanged. When the nuclear magnetic resonance coil port 16 leaves the inside of the installation box 11, the combination plate 3 112 leaves from the inside of the operating channel 111.

[0040] When the pneumatic telescopic rod 24 has finished working, the staff places the nuclear magnetic resonance coil on the top of the combined plate 110, and the operation channel 111 provides a channel for matching and connecting with the nuclear magnetic resonance coil plug 7. The combined plate 110 provides a support platform during the nuclear magnetic resonance coil repair and detection equipment 1 to detect the nuclear magnetic resonance coil, which is convenient for the placement of the nuclear magnetic resonance coil and allows the nuclear magnetic resonance coil to leave the top of the installation box 11, and will not affect the operation and viewing of the nuclear magnetic resonance coil vector network analysis module 12, the multi-channel RF signal multiplexer 13, the low noise preamplifier detection module 14 and the multi-channel signal acquisition and recording module 15.

[0041] Subsequently, the vector network analysis module 12, the multi-channel radio frequency signal multiplexer 13 and the multi-channel signal acquisition and recording module 15 are connected to the target nuclear magnetic resonance coil through the detection circuit and the corresponding radio frequency cable, and then the power switches of the vector network analysis module 12, the multi-channel radio frequency signal multiplexer 13, the low-noise preamplifier detection module 14 and the multi-channel signal acquisition and recording module 15 are turned on to start the vector network analysis module 12, the multi-channel radio frequency signal multiplexer 13, the low-noise preamplifier detection module 14 and the multi-channel signal acquisition and recording module 15. According to the model of the target nuclear magnetic resonance coil, the multi-channel radio frequency signal multiplexer 13 selects single / multi-channels and controls the working state of the tuning / tuning circuit of the selected channel by loading / unloading the DC bias voltage, and at the same time makes the receiving / transmitting circuit of the selected channel of the nuclear magnetic resonance coil work in a certain output mode, so as to realize the test of different functional parts of the nuclear magnetic resonance coil, and according to the model of the target nuclear magnetic resonance coil, the multi-channel signal acquisition and recording module 15 collects and records the working current signal of the selected single / multi-channel, and sets the normal working range of the current signal, and has an alarm function when it exceeds the range;

[0042] Subsequently, the resonance frequency of the corresponding nuclear magnetic system is confirmed, and the standing wave ratio, return loss and other parameters of the receiving / transmitting circuit of the selected channel are measured through the vector network analysis module 12 and the matching special detection probe. In the RF multiplexing working state, the vector network analysis module 12 measures the insertion loss parameters of each selected RF channel. If the measured insertion loss is out of tolerance, the cable fault point of each RF channel can be checked and analyzed through the vector network analysis module 12. In addition, the vector network analysis module 12 can be used in conjunction with the low-noise preamplifier detection module 14 to measure the amplification factor of the low-noise preamplifier of nuclear magnetic resonance coils of different brands, and compared with the test results of the normal nuclear magnetic resonance coil to confirm the working state of the target nuclear magnetic resonance coil. If it is unqualified, it can be repaired in a timely and targeted manner.

[0043] In addition, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, transmission frames 3 23 are fixedly connected to both ends of the transmission frame 1 21, two reserved channels 3 26 are provided on the outside of the installation box 11, and the two transmission frames 3 23 are respectively inserted into the two reserved channels 2 25, and the end of the transmission frame 3 23 away from the transmission frame 1 21 is fixedly connected to a curved surface block 214, and the curved surface block 214 abuts against the installation box 11, and the transmission frame 3 23 and the pneumatic telescopic rod 24 cooperate to limit and guide the movement of the transmission frame 1 21, so as to ensure that the transmission frame 1 21 can drive the combined plate 2 110 to smoothly return to the inside of the installation box 11, and the transmission frame 3 23 shares the force exerted on the pneumatic telescopic rod 24 to protect the pneumatic telescopic rod 24, and a blocking block 215 is provided on one side of the curved surface block 214, and the blocking block 215 is fixedly connected to the installation box 11 to seal the reserved channel 3 26, so as to prevent external impurities from entering the reserved channel 3 26 and affecting the movement of the transmission frame 3 23 and the curved surface block 214;

[0044] The storage box 27 in the limiting assembly is arranged inside the reserved channel three 26 and is fixedly connected to the transmission frame one 21. The storage box 27 and the blocking block 215 are arranged at both ends of the reserved channel three 26. The storage box 27 limits the movement of the curved block 214 to prevent the transmission frame three 23 from being completely separated from the installation box 11. The transmission frame three 23 supports the transmission frame one 21 to ensure the stability of the transmission frame one 21 and the combined plate two 110 in supporting the magnetic resonance coil.

[0045] In addition, such as Figure 7 and Figure 8 As shown, a card slot 212 is provided at the bottom of the storage box 27, and the card slot 212 is opened at the top of the transmission frame three 23, and a metal block 28 is provided at the bottom of the electromagnet 29 fixedly connected to the top of the inner cavity of the storage box 27. The metal block 28 is made of iron, and a spring-type telescopic rod 210 and two telescopic rods 1 211 are fixedly connected on both sides of the top of the metal block 28. The tops of the spring-type telescopic rod 210 and the telescopic rod 1 211 that can be telescoped are fixedly connected to the storage box 27. When the electromagnet 29 is not working, the spring-type telescopic rod 210 telescopes and pushes the metal block 28 downward, and the metal block 28 partially enters the card slot 212, so that the metal block 28 is partially in the card slot 212 and partially in the storage box 27. The metal block 28 plays a role in limiting the transmission frame three 23, ensuring the stability of the transmission frame three 23 staying inside the reserved channel three 26.

[0046] When the pneumatic telescopic rod 24 works, the electromagnet 29 works synchronously. The working electromagnet 29 pulls the metal block 28 upward through magnetic force, so that the metal block 28 leaves the inside of the slot 212, and the transmission frame three 23 loses its fixation, so that the transmission frame one 21 and the transmission frame three 23 can move.

[0047] In addition, such as Figure 7 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, two connecting rods 31 are fixedly connected between the handle 1 32 and the installation box 11 , and the handle 1 32 and the two connecting rods 31 form a U-shaped handle on one side of the installation box 11 , which facilitates the transportation of the nuclear magnetic resonance coil repair and detection equipment 1 .

[0048] The two pull wires 34 inserted in the two wire tubes 33 fixedly connected on both sides of the grip 1 32 are respectively fixedly connected to the two transmission frames 3 23. When the transmission frame 1 21 moves away from the installation box 11, the transmission frame 3 23 moves to apply tension to the pull wire 34. A take-up frame 36 is fixedly connected to the other end of the pull wire 34. Part of the pull wire 34 is wrapped around the take-up frame 36. The installation cross bar 310 fixedly connected inside the take-up frame 36 is rotatably connected to the grip 1 32. When the transmission frame 3 23 pulls the pull wire 34, the installation cross bar 310 and the take-up frame 36 rotate to unwind the pull wire 34. A circular groove 216 is provided on the transmission frame 3 23, and one end of the wire tube 33 passes through the blocking block 215 and then extends into the circular groove 216, and one end of the pull wire 34 guided by the wire tube 33 is pulled by the transmission frame 3 23; a torsion spring 39 is installed inside the torsion spring box 38 provided on one side of the mounting cross bar 310, and one end of the torsion spring 39 extends to the outside of the torsion spring box 38 and is fixedly connected to the mounting cross bar 310. When the mounting cross bar 310 rotates, the torsion spring 39 installed inside the torsion spring box 38 fixedly installed by the handle 1 32 is rolled up to the outside of the mounting cross bar 310;

[0049] When the transmission frame 3 23 is reset, the torsion spring 39 rebounds and drives the installation cross bar 310 to rotate, so that the installation cross bar 310 drives the take-up frame 36 to rotate and reel in excess pull wire 34, so that the pull wire 34 is always in a taut state, avoiding the pull wire 34 from affecting the transportation of the nuclear magnetic resonance coil repair detection equipment 1, and ensuring the service life of the peripheral structure 3.

[0050] A storage groove 35 is provided on one side of the grip 1 32, and two telescopic rods 2 311 are arranged inside the storage groove 35. A grip 2 315 is fixedly connected between the two telescopic rods 2 311 that can be extended and retracted, and the grip 2 315 can move on one side of the grip 1 32. When the user advances the nuclear magnetic resonance coil repair and detection device 1 by the handle, under the action of the weight of the nuclear magnetic resonance coil repair and detection device 1, the grip 2 315 moves and fits tightly against the grip 1 32, and the clamping rod 313 inserted in the clamping box 312 is fixedly connected to the grip 2 315. Therefore, when the grip 2 315 moves toward the grip 1 32 and the two fit tightly, the clamping rod 313 moves toward the clamping box 312, and the pull wire 34 passes through the wire groove 314 provided on the clamping box 312, so the clamping rod 313 squeezes the part of the wire groove 314 located inside the clamping box 312, and the clamping box 312 and The handle 32 is fixedly connected and cannot move, so that the pull wire 34 is clamped and limited by the clamping box 312 and the clamping rod 313, and the transmission frame 3 23 to which the pull wire 34 is fixed is limited and cannot move, so that the nuclear magnetic resonance coil repair and detection equipment 1 is lifted. During the movement, the weight of the nuclear magnetic resonance coil repair and detection equipment 1 acts on the pull wire 34 and is converted into a force to limit the transmission frame 3 23 and the transmission frame 1 21, so as to avoid the situation that the transmission frame 1 21 can move to drive the nuclear magnetic resonance coil port 16 to leave the installation box 11 when the pneumatic telescopic rod 24 and the spring telescopic rod 210 are out of control due to the shaking and vibration of the nuclear magnetic resonance coil repair and detection equipment 1, thereby ensuring the safety of the nuclear magnetic resonance coil port 16 and reducing the damage to the internal equipment of the nuclear magnetic resonance coil repair and detection equipment 1 caused by the movement of the nuclear magnetic resonance coil repair and detection equipment 1.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
