[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] Please refer to Figures 1-4 , a magnetic levitation centrifugal chiller for industrial cooling, including a chiller 1. One end of a corrugated pipe 2 is fixedly communicated with the input end of the chiller 1, and one end of the corrugated pipe 2 far from the chiller 1 is fixedly communicated with a water inlet pipe 3. A fixing seat 4 is fixedly installed on the outer surface of the chiller 1. Above the fixing seat 4, a support frame 7 is movably installed through an adjusting mechanism. A retaining mechanism for stably clamping the water inlet pipe 3 is arranged on the support frame 7.

[0021] Through the above technical solution, when the device is in use, the water inlet pipe 3 can be stably clamped by the retaining mechanism, and the intervention angle of the water inlet pipe 3 can be adjusted in cooperation with the adjusting mechanism. The corrugated pipe 2 with excellent deformation ability can keep the water inlet pipe 3 and the chiller 1 in a good sealed connection state all the time.

[0022] Specifically, the adjusting mechanism includes a retaining strip 5 fixedly connected to the inner side of the fixing seat 4. The top of the retaining strip 5 is rotatably connected to a head shaft 6, and the outer surface of the head shaft 6 is rotatably connected to the bottom of the support frame 7.

[0023] Through the above technical solution, the retaining strip 5 and the electric push rod 9 together play a role in supporting the support frame 7.

[0024] Specifically, a rod head shaft 8 is fixedly connected to the inner side of the fixing seat 4. The outer surface of the rod head shaft 8 is rotatably connected to an electric push rod 9. The output end of the electric push rod 9 is rotatably connected to a push-pull rod 10, and the outer surface of the push-pull rod 10 is rotatably connected to the bottom of the support frame 7.

[0025] Through the above technical solution, the design of the rod head shaft 8 is to facilitate the micro-rotation of the electric push rod 9 itself during the process of the electric push rod 9 pushing the support frame 7 to deflect.

[0026] Specifically, the retaining mechanism includes an arc seat 11 fixedly installed on the upper surface of the support frame 7. A seat shaft 12 is fixedly penetrated through the inner side of the arc seat 11.

[0027] Through the above technical solution, the arc seat 11 and the clamping arc frame 13 can clamp the water inlet pipe 3. During this process, the clamping arc frame 13 needs to rotate along the seat shaft 12 to adjust the position.

[0028] Specifically, the outer surface of the seat shaft 12 is rotatably connected with an arc holder 13 , and the arc holder 13 has a groove at one end away from the seat shaft 12 , and a rotating shaft 14 is fixedly penetrated at one end of the arc seat 11 away from the seat shaft 12 .

[0029] Through the above technical solution, when the sleeve 15 rotates along the rotating shaft 14, the screw 16 can be driven to move synchronously, so that the screw 16 can be embedded in the groove.

[0030] Specifically, the outer surface of the rotating shaft 14 is rotatably connected with a shaft sleeve 15 , the outer surface of the shaft sleeve 15 is provided with a screw 16 , and the outer surface of the screw 16 is threadedly sleeved with a nut 17 .

[0031] Through the above technical solution, after the screw 16 is embedded in the groove, the screw 16 can be stably limited by the nut 17, so that the arc bracket 13 can stably clamp the water inlet pipe 3 on the arc seat 11.

[0032] Working principle: When the device is in use, the water inlet pipe 3 is first passed through the arc seat 11, and the arc seat 11 supports the water inlet pipe 3, and then the arc frame 13 is rotated along the seat shaft 12 until the arc frame 13 tightly clamps the water inlet pipe 3, and then the screw 16 is turned to drive the sleeve 15 to rotate along the rotating shaft 14. When the screw 16 is embedded in the groove, the nut 17 can be screwed along the screw 16. When the nut 17 moves down along the screw 16 to tightly against the arc frame 13, the water inlet pipe 3 is stably clamped between the arc seat 11 and the arc frame 13. At this time, in order to reduce the influence of the position of the connection point of the water inlet pipe 3 on the surrounding environment or other equipment and ensure that the water inlet pipe 3 is at a more ideal access angle, the electric push rod 9 can be opened to push the support frame 7. The push rod 9 is pushed, during which the output end of the electric push rod 9 will rotate along the push-pull rod 10, and a force will be applied to the support frame 7 through the push-pull rod 10. At the same time, the bottom end of the electric push rod 9 will rotate along the rod head axis 8 during the pushing process. After the support frame 7 is pushed, it will rotate along the end axis 6, and the end away from the retaining strip 5 will gradually rise, thereby driving the water inlet pipe 3 above to deflect at an angle. In the process of deflecting the water inlet pipe 3 to adjust to a suitable access angle, the corrugated tube 2 will undergo corresponding deformation and always keep the water inlet pipe 3 and the chiller 1 in a good and sealed connection state, ultimately making the connection point position of the water inlet pipe 3 more flexible and can be adjusted according to actual conditions to meet the needs of different buildings or equipment layouts.

[0033] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
