Description

Technical Field

[0001] This invention provides a support structure for a superconducting filter, belonging to the field of superconducting filter technology. Background Technology

[0002] Superconducting filters, as high-performance electronic devices, have shown great promise in numerous fields such as communications, radar, and radio astronomy. A key prerequisite for superconducting filters to perform their excellent functions is a stable low-temperature environment. This is because superconducting materials only exhibit superconducting properties below their critical temperature. To achieve and maintain such low-temperature conditions, superconducting filters are typically placed in specially designed cryogenic storage containers, creating a stable low-temperature operating environment for them.

[0003] In existing superconducting filter system designs, the support structure plays an indispensable role. Its main function is to provide stable support and fixation for the superconducting filter, ensuring its stable position within the cryogenic storage container and preventing displacement or damage due to external vibrations, impacts, or other factors. Current installation methods typically involve placing the superconducting filter into the cryogenic storage container first, followed by fixing it in place. However, the internal space of cryogenic storage containers is usually quite confined, which greatly complicates the filter fixing process. Operators find it difficult to accurately position and fix the filter within this limited space, resulting in low installation efficiency and a high risk of damage due to improper handling. Therefore, there is an urgent need to develop a novel support structure to address these problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that when a superconducting filter is placed in a low-temperature, narrow storage container, it is inconvenient to position, support, and fix the superconducting filter.

[0005] To solve the above problems, the proposed technical solution is as follows: a support structure for a superconducting filter, including a housing and an end cap, the end cap sealing the upper end of the housing, a refrigeration unit for cooling the housing being provided outside the housing, and the filter being located inside the housing; mounting plates are fixedly connected to both sides of the filter, and mounting holes are provided on the mounting plates.

[0006] A support base is fixedly installed inside the housing. The filter is positioned above the support base and does not contact the support base. Two lower insertion rods are slidably installed on the support base and are inserted into the mounting holes. A lower limit plate is fixedly sleeved on the lower insertion rod and the mounting plate presses against the lower limit plate. Two upper insertion rods are slidably installed below the end cover and are inserted into the mounting holes. An upper limit plate is fixedly sleeved on the upper insertion rod and presses against the mounting plate.

[0007] As an improvement, the lower insert and the upper insert each occupy half the space of the mounting hole.

[0008] As an improvement, a bidirectional screw is rotatably connected inside the support base, and two movable blocks are provided inside the support base, with the two movable blocks respectively threaded to the corresponding positions of the bidirectional screw; a groove is provided on the support base, and the lower insertion rod passes through the groove and is fixedly connected to the movable block.

[0009] As an improvement, the operating end of the bidirectional screw is located outside the housing.

[0010] As an improvement, a sliding groove is provided inside the end cap, and a slider is slidably disposed in the sliding groove; a guide groove communicating with the sliding groove is provided at the bottom of the end cap, and the upper insertion rod passes through the guide groove and is fixedly connected to the slider.

[0011] As an improvement, the enclosure is provided with a wire-passing hole for the wire to pass through the enclosure and connect to the filter connector.

[0012] The beneficial effects of this utility model are:

[0013] The lower insertion rod is inserted into the mounting hole, and a lower limiting plate is fixedly sleeved on the lower insertion rod, with the mounting plate pressing against the lower limiting plate. By setting the lower insertion rod and the lower limiting plate, the superconducting filter can be positioned and supported. At the same time, the lower insertion rod can slide on the support base to accommodate different superconducting filters. Two upper insertion rods are slidably set below the end cap, and the upper insertion rods are inserted into the mounting hole. By setting the upper insertion rods and the upper limiting plate, in conjunction with the lower insertion rods and the lower limiting plate, the superconducting filter can be fixed while the end cap is installed, without the need to insert fasteners or tools into the narrow housing, making operation convenient.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] according to Figure 1-4 As shown: This utility model provides a support structure for a superconducting filter: including a housing 1, an end cap 2, the end cap 2 sealing the upper end of the housing 1, a refrigeration unit 6 for cooling the housing 1 is provided outside the housing 1, and the filter 4 is located inside the housing 1; the housing 1 has a wire hole 5 for the wire to pass through the housing 1 and connect to the filter 4 connector 3; mounting plates 7 are fixedly connected to both sides of the filter 4, and mounting holes 14 are provided on the mounting plates 7;

[0021] like Figure 2 , 3 As shown, a support base 8 is fixedly installed inside the housing 1, and the filter 4 is installed above the support base 8 without contacting the support base 8. Two lower insertion rods 15 are slidably installed on the support base 8 and are inserted into the mounting holes 14. A lower limit plate 16 is fixedly sleeved on the lower insertion rods 15, and the mounting plate 7 presses on the lower limit plate 16. By setting the lower insertion rods 15 and the lower limit plate 16, the filter 4 can be initially positioned and supported.

[0022] like Figure 4 As shown, a bidirectional screw 17 is rotatably connected inside the support base 8. Two movable blocks 18 are provided inside the support base 8, and the two movable blocks 18 are threadedly connected to corresponding positions of the bidirectional screw 17. A groove 19 is provided on the support base 8, and the lower insertion rod 15 passes through the groove 19 and is fixedly connected to the movable block 18. The operating end of the bidirectional screw 17 is located outside the housing 1 for easy operation. By setting the bidirectional screw 17, the distance between the two lower insertion rods 15 can be easily adjusted, thus making it suitable for different filters 4.

[0023] like Figure 3 As shown, two upper insertion rods 12 are slidably disposed below the end cap 2, and the upper insertion rods 12 are inserted into the mounting holes 14; an upper limit plate 13 is fixedly sleeved on the upper insertion rods 12, and the upper limit plate 13 presses on the mounting plate 7. The lower insertion rod 15 and the upper insertion rod 12 each occupy half of the space of the mounting hole 14, which can ensure that both the upper and lower insertion rods can be inserted into the mounting hole 14, and at the same time, they work with the upper limit plate 13 and the lower limit plate 16 to fix the mounting plate 7 and the filter 4. A sliding groove 11 is opened in the end cap 2, and a slider 10 is slidably disposed in the sliding groove 11; a guide groove 9 communicating with the sliding groove 11 is opened at the bottom of the end cap 2, and the upper insertion rod 12 passes through the guide groove 9 and is fixedly connected to the slider 10. By setting the sliding upper insertion rod 12, the position of the upper insertion rod 12 can be adjusted according to different filters 4; at the same time, there is a large friction between the slider 10 and the sliding groove 11, which can ensure that after the position of the upper insertion rod 12 is adjusted, the friction can be used to increase the stability of the upper insertion rod 12.

[0024] The principle of this utility model

[0025] like Figure 4 As shown, before inserting the superconducting filter 4, with the end cap 2 open, first adjust the spacing of the two lower insertion rods 15. Tighten the bidirectional screw 17, and use the moving block 18 to slide the two lower insertion rods 15 so that the spacing of the two lower insertion rods 15 corresponds to the spacing of the two mounting holes 14 of the superconducting filter 4. Directly place the superconducting filter 4 into the housing 1, so that the lower insertion rods 15 are inserted into the mounting holes 14, and then use the lower limit plate 16 to position and support the mounting plate 7 and the superconducting filter 4. Connect the superconducting filter 4 through the wiring hole 5. After sealing the wiring hole 5, adjust the spacing of the two upper insertion rods 12 according to the spacing of the two mounting holes 14; as... Figure 3 As shown, simply move the upper insertion rod 12 to position it corresponding to the mounting hole 14. Then, directly install the end cap 2. While the end cap 2 is connected to the housing 1, the upper insertion rod 12 can be inserted into the mounting hole 14. Then, the upper positioning plate 13 presses onto the mounting plate 7, thus completing the installation and fixation of the superconducting filter 4. When installing and fixing the superconducting filter 4, positioning is convenient. The mounting plate 7 and mounting hole 14 allow for quick positioning, and the superconducting filter 4 can be fixed simultaneously with the installation of the end cap 2, eliminating the need to insert fasteners or tools into the narrow housing 1, thus improving the ease of operation.
