Description

Technical Field

[0001] This utility model relates to the field of superconducting coil technology, and in particular to a superconducting coil grease-impregnation device. Background Technology

[0002] Resin impregnation is a crucial step in the molding of superconducting coils, serving to fix the internal circuitry and provide shock absorption. Poor impregnation results in incomplete penetration and filling of the superconducting coil, leading to poor fixation of the internal circuitry, loosening of the circuitry, and significantly increasing the risk of quenching failure in the superconducting magnet.

[0003] Therefore, designing a superconducting coil grease-impregnation device has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a superconducting coil grease dipping device in response to the above-mentioned shortcomings. This device can complete the segmented grease dipping of the superconducting coil using clamps, which facilitates the observation and control of the resin liquid level inside the clamps. It has the advantages of simple structure and high grease dipping quality.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A superconducting coil grease-impregnation device includes a clamp that provides a accommodating chamber for the superconducting coil, a measuring tube disposed outside the clamp, and a liquid level sensing device disposed on the side of the measuring tube. The measuring tube is connected to the bottom of the clamp; a delivery pipe is connected to the bottom of the clamp.

[0007] As an improvement, the measuring tube is a transparent flexible tube with graduation markings, and the liquid level sensing device includes multiple infrared liquid level sensors arranged sequentially and at intervals from top to bottom.

[0008] As an improvement, a resin tank is also included, which is connected to the bottom of the clamp via a delivery pipe; the delivery pipe is equipped with a delivery valve.

[0009] As an improvement, the top of the clamp is provided with a vent.

[0010] As an improvement, the clamp is a horizontally arranged cylindrical structure, including an upper clamp and a lower clamp that are fastened together; both ends of the superconducting coil are provided with end plates, and the inner diameter of the clamp is adapted to the outer diameter of the end plates; a sealing element is provided between the clamp and the two end plates.

[0011] As an improvement, both the upper and lower clamps are provided with connecting parts, which are located at the fastening point of the upper and lower clamps; the connecting parts are provided with mounting holes, and the upper and lower clamps are fixedly connected through the mounting holes and connecting parts.

[0012] As an improvement, the upper clamp is provided with a vent.

[0013] The present invention adopts the above technical solution and has the following advantages compared with the prior art:

[0014] The clamp can be used to complete the segmented grease impregnation of superconducting coils, which makes it easy to observe and control the resin liquid level inside the clamp. It has the advantages of simple structure and high grease impregnation quality.

[0015] The superconducting coil grease-impregnating device using this technical solution can perform segmented grease-impregnation of the superconducting coil, that is, grease-impregnating the superconducting coil from bottom to top: bottom grease-impregnation, middle grease-impregnation, and top grease-impregnation. When the resin in the grease-impregnating device reaches the set height, the supply of resin to the grease-impregnating device will be stopped immediately, and then the grease will be left to stand for grease impregnation.

[0016] By setting more infrared liquid level sensors on the liquid level sensing device, it is possible to achieve segmented grease immersion of more sections of the superconducting coil.

[0017] During the immersion process, it is convenient to observe and control the resin level and usage, and to monitor the resin level in real time, thereby improving the quality of the immersion process.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a superconducting coil grease impregnation device includes a resin tank 1, a clamp 4 providing a accommodating chamber for the superconducting coil 3, a measuring tube 5 disposed outside the clamp 4, and a liquid level sensing device 6 disposed on the side of the measuring tube 5. The clamp 4 is fixedly mounted on a mounting base 16; the resin tank 1 is connected to the bottom of the clamp 4 via a delivery pipe 7; a delivery valve 2 is provided on the delivery pipe 7. The resin tank 1 delivers resin into the clamp 4 through the delivery pipe 7.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the measuring tube 5 and the level sensing device 6 are fixedly mounted on one side of the clamp 4. Any existing technical solution that can fix the measuring tube 5 and the level sensing device 6 to one side of the clamp 4 can be used in this application, and will not be elaborated here. Preferably, the measuring tube 5 and the level sensing device 6 are fixedly mounted on the mounting base 16. The measuring tube 5 is connected to the bottom of the clamp 4. In this embodiment, preferably, the measuring tube 5 is a transparent flexible tube with graduation marks. The measuring tube 5 includes a vertically arranged level display section, and the upper end of the measuring tube 5 is higher than the top of the superconducting coil 3. When resin is poured into the clamp 4, the resin level inside the clamp 4 can be clearly seen through the measuring tube 5. The level sensing device 6 includes multiple infrared level sensors 8 arranged sequentially and at intervals from top to bottom. The multiple infrared level sensors 8 are used to monitor the liquid level inside the measuring tube 5. In this embodiment, three infrared liquid level sensors 8 are used as an example. In actual use, the number and position of infrared liquid level sensors 8 can be set on the liquid level sensing device 6 according to factors such as the structure and size of the superconducting coil 3. According to the scale markings on the measuring tube 5, three corresponding heights are selected on the liquid level sensing device 6 to set one infrared liquid level sensor 8. When the resin liquid level in the measuring tube 5 reaches the specified height, the corresponding infrared liquid level sensor 8 will emit an electrical signal to monitor the resin liquid level in the clamp 4.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the clamp 4 is a horizontally arranged cylindrical structure, including an upper clamp 10 and a lower clamp 11 that are fastened together. A vent 9 is provided at the top of the clamp 4, and the vent 9 is located on the upper clamp 10. The superconducting coil 3 is a hollow cylindrical structure with end plates 13 at both ends. The inner diameter of the clamp 4 matches the outer diameter of the end plates 13; a sealing element 12 is provided between the clamp 4 and both end plates 13. When the upper clamp 10 and lower clamp 11 are fastened together, they are sealed and fixed to the end plates 13 of the superconducting coil 3 through the sealing elements 12 at both ends, providing a accommodating chamber for grease impregnation of the superconducting coil 3.

[0031] Both the upper clamp 10 and the lower clamp 11 are provided with connecting portions 14, which are located at the engagement point of the upper clamp 10 and the lower clamp 11. The connecting portion 14 is provided with mounting holes 15, through which the upper clamp 10 and the lower clamp 11 are fixedly connected by a connector. Bolts or nuts can be used as connectors. Preferably, in this embodiment, a sealing gasket is provided between the connecting portions 14 of the upper clamp 10 and the lower clamp 11 for sealing.

[0032] In use, first place the superconducting coil 3 on the lower clamp 11, then fasten the upper clamp 10 onto the lower clamp 11. During installation, install a sealing element 12 between the end plate 13 of the superconducting coil 3 and the upper and lower clamps 10 and 11, and fix the upper and lower clamps 10 and 11 together with fasteners. Open the delivery valve 2 and deliver the resin in the resin tank 1 to the clamp 4 through the delivery pipe 7. The measuring tube 5 is connected to the clamp 4, and the resin level in the measuring tube 5 is the same as the resin level in the clamp 4; the measuring tube 5 is a transparent flexible tube with graduation marks.

[0033] When the resin level in measuring tube 5 reaches the height corresponding to the lowest position infrared level sensor 8, the infrared level sensor 8 will emit an electrical signal. At this time, the delivery valve 2 will be closed to stop the continued delivery of resin into the clamp 4. The superconducting coil 3 will then be allowed to stand for low-level resin impregnation. If the resin level drops during the standing process, meaning the electrical signal from the infrared level sensor 8 at that position is no longer received, the delivery valve 2 will open to deliver resin into the clamp 4 to the height corresponding to the lowest position infrared level sensor 8, i.e., the resin height set for low-level impregnation; this ensures that the resin level remains at the set height during the standing impregnation process, guaranteeing the quality of the impregnation.

[0034] When the set set time is reached, the control delivery valve 2 opens to continue delivering resin into the clamp 4, so that the resin liquid level in the clamp 4 and the measuring tube 5 reaches the next settling and immersion height. The infrared liquid level sensor 8 at the corresponding height will send an electrical signal to close the delivery valve 2 and stop delivering resin into the clamp 4. The second settling and immersion process is the same as the first settling and immersion process.

[0035] After the second static immersion is completed, subsequent static immersions are carried out until the final static immersion is completed.

[0036] Using this superconducting coil grease-dipping device, the superconducting coil can be greased in sections, that is, from bottom to top: bottom, middle, and top. When the resin in the grease-dipping device reaches the set height, the supply of resin to the device will immediately stop, and then the grease will be left to stand. Of course, by setting more infrared liquid level sensors 8 on the liquid level sensing device 6, more sections of the superconducting coil can be greased in sections.

[0037] During the immersion process, it is convenient to observe and control the resin level and usage, and to monitor the resin level in real time, thereby improving the quality of the immersion process.

[0038] In summary, this utility model provides a superconducting coil grease-impregnation device. This device can complete the segmented grease-impregnation of superconducting coils using clamps. During the grease-impregnation process, it is convenient to observe and control the resin liquid level and usage, and to monitor the resin liquid level in real time, thereby improving the quality of the grease-impregnation process. It has the advantages of simple structure and high grease-impregnation quality.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
