[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1

[0040] Reference Figure 1-2, which is the first embodiment of the present invention, provides a magnetic ring for an ice melting device, including a magnetic ring assembly 100, which includes a clamping plate 101, a plurality of core pieces 102 spaced apart inside the clamping plate 101 for adjusting electrical parameters, and conductive rows 103 for supplying power to the core pieces 102 are installed at both ends of the clamping plate 101; the core piece 102 includes two core bodies 102a symmetrically fitted together, and a connecting clamp 102b is sleeved and connected to the two core pieces 102, and the connecting clamp 102b is fixed by a connecting bolt 102e, so as to adjust the pressure of the core body 102a and change the electrical parameters.

[0041] The clamping plate 101 has a plurality of cavities for accommodating the core member 102, and the clamping plate 101 has a plurality of connecting screws 101a, which fix the core member 102 by tightening the clamping plate 101, and nuts are connected to both ends of the connecting screws 101a, and insulating gaskets 101d are installed between the nuts and the clamping plate 101. The clamping plate 101 has a plurality of mounting holes, and insulating beams 101c are fixed to the mounting holes by screws, and the conductive row 103 is connected to the insulating beams 101c by screws;

[0042] Among them, two insulating clamps 101b are provided inside the clamp 101, and the insulating clamps 101b are fixed to the mounting holes by screws. The two insulating clamps 101b clamp the conductive row 103 in the middle. The four corners of the clamp 101 are fixed with mounting angle pieces 101e, and insulating supports 101f are fixedly connected below the mounting angle pieces 101e.

[0043] Specifically, the length of the clamping plate 101 is adjustable, which means that the number of the core pieces 102 can be changed as needed, thereby adjusting the electrical parameters of the magnetic ring of the ice melting device.

[0044] The connecting screw 101a is used to fix the clamping plate 101 and the core member 102, and the insulating gasket 101d ensures that the clamping plate 101 does not form an electrical path with the connecting screw 101a, thereby avoiding a short circuit of the core member 102 and improving the safety of the equipment.

[0045] The insulating beam 101c is fixed through the mounting hole on the clamping plate 101, and the conductive row 103 is fixed on the insulating beam 101c. This design ensures the stability of the conductive row 103, and when the conductive row 103 is long, its vibration can be prevented by increasing the number of insulating clamps 101b.

[0046] The insulating clamp 101b is used to fix the conductive bus 103 to prevent it from vibrating during operation, thereby maintaining the stability of the circuit.

[0047] Corner pieces 101e and insulating supports 101f are installed, which provide additional structural support, ensuring the stability and durability of the assembly.

[0048] A through-hole steel column 102c and a threaded steel column 102d are fixed to the first and second ends of the connecting clamp 102b respectively. The connecting bolt 102e passes through the through-hole steel column 102c and the threaded steel column 102d to fix the connecting clamp 102b. A clamping spring 102f is provided between the through-hole steel column 102c and the connecting bolt 102e. The clamping spring 102f is sleeved on the outside of the connecting bolt 102e. A filling gasket 102g is provided between the two core bodies 102a.

[0049] refer to Figure 2 , the core body 102a is the main part of the magnetic ring of the ice melting device, and is used to guide the magnetic flux;

[0050] The compression spring 102f provides the necessary elastic force to adjust the pressure of the connection clamp 102b when tightening or loosening the connection bolt 102e;

[0051] The through-hole steel column 102c serves as a guide structure for the connecting bolt 102e to pass through, and is used in conjunction with the connecting clamp 102b;

[0052] The threaded steel column 102d cooperates with the connecting bolt 102e to adjust the tightness of the connecting clamp 102b;

[0053] The connecting bolt 102e is screwed into the threaded steel column 102d to adjust the pressure of the compression spring 102f, thereby adjusting the tightness of the connecting clamp 102b;

[0054] Connect the clamp 102b to fix the two core bodies 102a to ensure that they are correctly placed on top of each other;

[0055] The gap-filling gasket 102g is placed between the contact surfaces of the two core bodies 102a to adjust the gap between the core bodies 102a and affect the electrical characteristics of the magnetic ring of the ice-melting device.

[0056] With such a design, the pressure of the compression spring 102f can be adjusted by turning the connection bolt 102e, thereby adjusting the tightness of the connection clamp 102b to change the gap between the core bodies 102a, thereby adjusting the electrical parameters of the magnetic ring of the ice melting device. The gap-filling gasket 102g is preferably made of rubber material with good insulation.

[0057] In general, the design of the ice-melting device magnetic ring allows flexible adjustment of electrical parameters, provides good structural stability, and improves safety by using insulating materials. The application of this ice-melting device magnetic ring in the ice-melting device can replace the traditional inductor, which not only reduces the size and weight of the equipment, but also helps to reduce costs. The advantage of this design lies in its modularity and adjustability, which allows it to be adjusted and optimized according to different application requirements.

[0058] Example 2

[0059] Reference Figure 2-5 , which is the second embodiment of the present invention, and is different from the previous embodiment in that it further includes a pressure display assembly 200, which is used to display the tightening degree of the connection clamp 102b, and includes a tension member 201, an opposite driving member 202 and a display member 203. The tension member 201 is located inside the connection bolt 102e, and the tension member 201 is driven by an external force to drive the opposite driving member 202 to push the display member 203 to slide out from the inside of the connection bolt 102e. The tension member 201 includes a tension rod 201a arranged at the upper end of the connection bolt 102e, a tension groove 201b for accommodating the sliding of the tension rod 201a is provided inside the connection bolt 102e, a protruding limit strip 201c is provided on the outside of the tension rod 201a, a tension spring 201d is fixedly connected to the bottom of the tension rod 201a, and a connection screw hole 102e-1 is fixed to the top of the tension rod 201a. The driving member 202 includes a first driving rod 202a fixed to the bottom of the tension rod 201a, a second driving rod 202d is provided on one side of the first driving rod 202a, a gear 202c is provided between the second driving rod 202d and the first driving rod 202a, and a tooth groove 202b meshing with the gear 202c is provided on both the first driving rod 202a and the second driving rod 202d. The display member 203 includes a display rod 203a fixed to the bottom end of the second driving rod 202d, and a plurality of annular scale lines 203b are provided on the outer side of the display rod 203a.

[0060] As can be seen from Example 1, the shim 102g itself has a certain elasticity, and the staff cannot apply the same pressure to each shim 102g through the connecting bolts 102e, resulting in different gaps between the core bodies 102a, affecting the electrical parameters.

[0061] When the connecting bolt 102e applies pressure to the compression spring 102f through the tension piece 201, the reaction force applied by the compression spring 102f to the connecting screw hole 102e-1 overcomes the elastic force of the tension spring 201d. The connecting screw hole 102e-1 drives the first driving rod 202a to slide through the tension rod 201a. When the first driving rod 202a slides, it drives the meshing gear 202c to rotate. When the gear 202c rotates, it pushes the meshing second driving rod 202d to slide down. The second driving rod 202d pushes the display rod 203a to slide out of the connecting bolt 102e. The staff can know the pressure value applied to the connecting clamp 102b by observing the annular scale line 203b on the display rod 203a, which is convenient for adjusting the gap between multiple core bodies 102a and is easy to use.

[0062] In addition, when the staff performs maintenance, by observing the values ​​of each annular scale line 203b, it is possible to quickly determine whether the current connecting bolt 102e is loose, thereby improving maintenance efficiency.

[0063] The limit strip 201c guides the sliding of the tension rod 201a, thereby preventing the tension rod 201a from idling and causing the connection bolt 102e to be unable to rotate normally.

[0064] That is to say, through the tension piece 201, it can be ensured that the connecting bolt 102e applies the same pressure to each connecting clamp 102b, so that the gap between the core bodies 102a remains consistent; the annular scale line 203b on the display rod 203a allows the staff to intuitively see the applied pressure value, which helps to quickly and accurately adjust the gap; the design of the annular scale line 203b enables the staff to quickly determine whether the connecting bolt 102e is loose, so as to quickly perform necessary maintenance, improve maintenance efficiency, not only improve the reliability of the equipment, but also simplify the maintenance process, making the operation more convenient and quick.

[0065] Example 3

[0066] Reference Figure 5-6 , which is the third embodiment of the present invention, and this embodiment further provides a magnetic ring for an ice melting device. It includes a damping assembly 300, which is used to increase the rotation damping of the connecting bolt 102e, and includes a fixing rod 301 fixed inside the connecting bolt 102e, and a compression chamber 302 for accommodating the sliding of the bottom end of the fixing rod 301 is opened inside the display rod 203a, and a piston 303 is fixed to the part of the fixing rod 301 located in the compression chamber 302. The damping assembly 300 also includes a plurality of elastic damping rods 305 located outside the connecting bolt 102e, one end of the elastic damping rod 305 is hinged to the connecting bolt 102e, and a deformation expansion layer 306 for driving the elastic damping rod 305 to operate is fixed to the outside of the connecting bolt 102e, and the deformation expansion layer 306 is connected to the compression chamber 302 through a connecting cavity 304.

[0067] Specifically, when the display rod 203a slides downward, the gas above the piston 303 will be squeezed into the connecting cavity 304, and the connecting cavity 304 will transport the gas to the deformation expansion layer 306. The deformation expansion layer 306 itself expands, thereby pushing the elastic damping rod 305 to rotate. The elastic damping rod 305 contacts the components, thereby increasing the damping of the rotation of the connecting bolt 102e, making it difficult for the connecting bolt 102e to loosen in a vibration environment. The damping component 300 uses the principles of gas dynamics and mechanical feedback to realize the function of automatically adjusting the damping, thereby improving the stability of the equipment in a vibration environment and reducing maintenance requirements.

[0068] The deformation expansion layer 306 is made of an elastic airbag material and has good expansion and contraction properties. When the deformation expansion layer 306 contracts, it can drive the elastic damping rod 305 to reset, thereby avoiding interference with other components.

[0069] In summary, the pressure of the compression spring 102f can be adjusted by screwing the connection bolt 102e, thereby adjusting the tightness of the connection clamp 102b to change the gap size between the core body 102a, thereby adjusting the electrical parameters of the magnetic ring of the ice melting device;

[0070] The tension piece 201 is used to make the connecting bolt 102e apply pressure to the compression spring 102f. At the same time, the reaction of the compression spring 102f on the connecting screw hole 102e-1 overcomes the elastic force of the tension spring 201d. The connecting screw hole 102e-1 drives the first driving rod 202a to slide through the tension rod 201a. When the first driving rod 202a slides, it drives the meshing gear 202c to rotate. When the gear 202c rotates, it pushes the meshing second driving rod 202d to slide down. The second driving rod 202d pushes the display rod 203a to slide out of the connecting bolt 102e. The staff can know the pressure value applied to the connecting clamp 102b by observing the annular scale line 203b on the display rod 203a, which is convenient for adjusting the gap between multiple core bodies 102a.

[0071] When the display rod 203a slides downward, the gas above the piston 303 will be squeezed into the connecting cavity 304, and the connecting cavity 304 will transport the gas to the deformation expansion layer 306. The deformation expansion layer 306 itself expands, thereby pushing the elastic damping rod 305 to rotate. The elastic damping rod 305 contacts the component, thereby increasing the damping of the rotation of the connecting bolt 102e, making it less likely for the connecting bolt 102e to loosen under a vibration environment.
