[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] As Figures 1-4 shown, a protection device for an electromechanical HVAC pipeline includes a protective cover 1. A plurality of connecting shafts 9 arranged in a circular array and distributed in a staggered manner are fixedly connected to the inner wall of the protective cover 1. A clamping arm is rotatably connected to the connecting shaft 9. The clamping arm mainly includes a plurality of fixing blocks 4. Adjacent two fixing blocks 4 are rotatably connected by a hinge, and the hinge axis connecting the adjacent two fixing blocks 4 is parallel to the central axis of the protective cover 1. A circular rack 2 is rotatably connected to the inner wall of the protective cover 1 near each connecting shaft 9. A gear 3 meshingly connected with a plurality of circular racks 2 is rotatably connected to the inner wall of the protective cover 1. The inner tooth surface of the circular rack 2 is rotatably connected to the fixing block 4 at the swinging end of the clamping arm through a pin shaft. And a plurality of fixing blocks 4 at the swinging ends of the clamping arms are distributed in a circular array in the protective cover 1. An annular chute 10 for sliding the circular rack 2 is provided on the inner wall of the protective cover 1. A rubber pad 5 is fixedly installed at one end of the fixing block 4 facing the central axis of the protective cover 1. Adjacent two gears 3 are rigidly connected by a pin shaft, and a motor 8 is fixedly installed on the inner wall of the protective cover 1. The main shaft of the motor 8 is fixedly connected to the pin shaft installed at the gear 3.

[0025] Adopting this technical solution, by setting the fixing block 4, the electromechanical HVAC pipeline can be clamped. And, by rotatably connecting between a plurality of fixing blocks 4, the electromechanical HVAC pipelines of different sizes can be clamped. Specifically, the electromechanical HVAC pipeline is placed at the central axis of the protective cover 1. The motor 8 rotates to drive the gear 3 to rotate. The gear 3 rotates to drive the circular rack 2 to rotate. The circular rack 2 rotates to drive the fixing block 4 connected thereto to move. During the movement of the fixing block 4, the connected plurality of fixing blocks 4 will continuously approach the central axis of the protective cover 1, so as to limit the electromechanical HVAC pipeline within the central axis of the protective cover 1. In addition, by using the motor 8 to drive the fixing block 4 to move, the automation degree of the device is higher, reducing the labor intensity of personnel. Further, by using the rubber pad 5 to contact the electromechanical HVAC pipeline, the surface of the pipeline can be protected from abrasion, and shock absorption and anti-slip can be achieved.

[0026] As Figure 1 and Figure 3As shown in the figure, the protective cover 1 is equally divided into two halves along one of the planes passing through the center line. One end of the splicing part of the two halves of the protective cover 1 is rotatably connected by a pin shaft, and the other end is threadedly connected with a bolt 7. The annular rack 2 is equally divided into two halves along one of the planes passing through the center line, and the tooth backs of the two halves of the annular rack 2 are magnetically attracted to the annular chute 10.

[0027] With this technical solution, when personnel use the device, first rotate and open the protective cover 1 through a splicing end, and pull out the pin shaft at the connection between the fixed block 4 and the annular rack 2, then the mechanical and electrical HVAC pipeline can be placed in the protective cover 1, and then rigidly fix the broken protective cover 1 with the bolt 7, making it more convenient to install the device on the pipeline.

[0028] As Figure 1 shown in the figure, there are several protective covers 1, and spherical joints are fixedly connected to both adjacent ends of the several protective covers 1. The spherical joint includes a ball seat 11 threadedly connected to the protective cover 1, and the other end of the ball seat 11 is movably connected to a ball head tube 6.

[0029] With this technical solution, by setting the spherical joint, the positions between two adjacent protective covers 1 can be freely adjusted, enabling the device to protect the bent mechanical and electrical HVAC pipeline. In addition, by threadedly connecting the ball seat 11 to the protective cover 1, the effect of disassembly and assembly can be achieved. Further, when repairing one of the protective covers 1, remove the ball seat 11, then only need to open the protective cover 1 that needs to be repaired, and the other protective covers 1 do not need to be modified.

[0030] Working principle: When personnel use it, first rotate and open the protective cover 1 at the splicing end through a pin shaft, and pull out the pin shaft at the connection between the fixed block 4 and the annular rack 2. Then place the mechanical and electrical HVAC pipeline in the protective cover 1, and after installing the pin shaft back to its original position, rigidly fix the broken protective cover 1 with the bolt 7. At this time, start the motor 8, and the motor 8 drives the fixed block 4 to approach the pipeline to limit the pipeline in the protective cover 1.

[0031] The wiring diagram of the motor 8 in the present utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. Its model is selected according to the actual use, so the control method and wiring layout of the motor 8 will not be explained in detail.
