[0002] The magnetic levitation compressor is a new type of high-efficiency, energy-saving and silent power mechanical compressor. Its working principle is mainly based on magnetic levitation technology, that is, using electromagnetic force to suspend the compressor rotor in the magnetic field to achieve contactless operation. This technology greatly reduces energy loss and noise generation, and improves the efficiency and reliability of the system.

[0003] The magnetic levitation compressor is usually composed of a centrifugal impeller, a compressor body, permanent magnet materials, electromagnetic bearings, an AC / DC power conversion system, a soft start control system, an electromagnetic bearing control system, guide vanes, and a drive shaft.

[0029] The utility model mainly comprises a base 101 and a fixed clamping assembly, and the base 101 is used to install the compressor body 102; in actual use, the staff first needs to place the compressor body 102 in the middle position on the base 101, and then control the driving structure to control the movable plate 103 to slide inside the base 101. When the movable plate 103 slides, the transverse clamping block inside the waist-shaped groove 104 is squeezed by the waist-shaped groove 104. Therefore, the two transverse clamping blocks will move relative to each other inside the waist-shaped groove 104 until the two transverse clamping blocks contact the compressor body 102 and clamp the compressor body 102 in the transverse direction; at the same time, when the movable plate 103 moves, the longitudinal clamping structure also fixes and clamps the compressor body 102 together with the transverse clamping block under the action of the driving structure, so that the purpose of clamping the compressor body 102 from both the transverse and longitudinal directions is achieved, so that the compressor body 102 can be installed more stably.

[0030] In some embodiments, the base 101 includes a mounting shell 106 and a top cover 107 , the top cover 107 is fixedly disposed on the mounting shell 106 , the fixed clamping assembly and the longitudinal clamping structure are both disposed inside the mounting shell 106 , and the transverse clamping plate 105 is slidably matched with the upper surface of the top cover 107 .

[0031] During actual use, the staff first installs the fixed clamping assembly and the longitudinal clamping structure inside the installation shell 106 and then snaps the top cover 107 together to fix the top cover 107 to the base 101. This arrangement facilitates the installation of the fixed clamping assembly and the longitudinal clamping structure.

[0032] In some embodiments, the transverse clamp includes a cylindrical slider 108 and a first T-shaped clamp 109. The cylindrical slider 108 is slidably set inside the waist-shaped groove 104. The cylindrical slider 108 is in line contact with the waist-shaped groove 104 and slides with the base 101. The first T-shaped clamp 109 is installed on the cylindrical slider 108.

[0033] In actual use, the first T-shaped clamp 109 is detachably connected to the cylindrical slider 108, and a threaded hole is provided on the cylindrical slider 108. A threaded rod is provided at the bottom of the first T-shaped clamp 109. After the threaded rod is threadedly engaged with the threaded hole, the first T-shaped clamp 109 is parallel to the side of the compressor body 102; the main function of the first T-shaped clamp 109 is to clamp and fix the side wall of the compressor body 102, and the main function of the cylindrical slider 108 is to drive the first T-shaped clamp 109 to slide on the top cover 107 after slidingly engaging with the waist-shaped groove 104.

[0034] In some embodiments, a slide groove 110 is provided on the top cover 107, and the vertical portion of the first T-shaped clamp 109 is used to slide inside the slide groove 110. The vertical portion of the first T-shaped clamp 109 is a prismatic structure, and the two side surfaces of the vertical portion are always in contact with the inner surface of the slide groove and slide together; the horizontal portion of the first T-shaped clamp 109 is used to slide together with the top cover 107.

[0035] In actual use, there are four slide grooves 110, two of which are horizontally arranged on the top cover 107, and the other two slide grooves 110 are longitudinally arranged on the top cover 107. The vertical part of the first T-shaped clamp 109 slides inside the slide groove 110. The purpose of setting the slide groove 110 is to make way for the sliding of the first T-shaped clamp 109 and enable the first T-shaped clamp 109 to slide stably.

[0036] In some embodiments, a sliding recess is provided inside the waist-shaped groove 104, and a sliding protrusion is provided on the cylindrical slider 108, and the sliding recess and the sliding protrusion are slidably matched.

[0037] In actual use, when the cylindrical slider 108 slides inside the waist-shaped groove 104, the sliding depression and the sliding protrusion limit the cylindrical slider 108 longitudinally, so that the cylindrical slider 108 can be prevented from moving longitudinally.

[0038] In some embodiments, the longitudinal clamping structure includes a moving block 112 and a second T-shaped clamp block 113. There are two moving blocks 112. Both moving blocks 112 are slidably set inside the mounting shell 106. The second T-shaped clamp block 113 is installed on the moving block 112.

[0041] In actual use, the guide rod 114 and the guide hole 115 are provided to facilitate guiding the sliding of the moving block 112 so that the moving block 112 is more stable when moving.

[0042] In some embodiments, the driving device includes a ball screw 116 and a screw nut 117. The ball screw 116 is rotatably arranged inside the mounting housing 106. The ball screw 116 has two sections of threads with opposite rotation directions. There are three screw nuts 117, and the three screw nuts 117 are respectively installed on two moving blocks 112 and a moving plate 103. The ball screw 116 is used to cooperate with the three screw nuts 117.

[0043] During actual use, the staff rotates the ball screw 116. Since the ball screw 116 has two sections of threads with opposite rotation directions, and the two screw nuts 117 are respectively located at two positions of threads with different rotation directions, after the ball screw 116 is rotated, the two moving blocks 112 will move toward each other, thereby driving the second T-shaped clamp 113 to clamp and fix the compressor body 102; at the same time, the rotation of the ball screw 116 will drive the moving plate 103 to move, and after the moving plate 103 moves, the two waist-shaped grooves 104 of the figure eight squeeze the waist-shaped clamps to make the two first T-shaped clamps 109 move relative to each other, thereby realizing the horizontal clamping and fixation of the compressor body 102.

[0044] In some embodiments, two limiting rings 118 are disposed on the ball screw 116 .

[0045] In actual use, the limiting ring 118 is provided to limit the movement of the movable plate 103 .

[0046] In some embodiments, rubber pads are disposed on the first T-shaped clamp block 109 and the second T-shaped clamp block 113 .

[0047] In actual use, the purpose of setting the rubber pad is to increase the friction between the first T-shaped clamp 109 and the second T-shaped clamp 113 and the side of the compressor body 102, so that the first T-shaped clamp 109 and the second T-shaped clamp 113 can clamp the compressor body 102 more stably.
