Description

Technical Field

[0001] This utility model relates to the field of blower technology, and in particular to a magnetic levitation blower with a protective structure. Background Technology

[0002] A magnetic levitation blower is a high-speed centrifugal blower that uses magnetic levitation bearing technology to achieve contactless and frictionless levitation operation of the rotor.

[0003] Especially for the sealing and protection of the entire magnetic levitation blower, when the blower is in use, it needs to be connected to the inverter cabinet, main control system and sensors inside the machine through multiple power lines and signal lines. These cable bundles need to pass through the holes (called "cable inlets" or "wire holes") pre-drilled on the main machine housing. Currently, the traditional sealing and protection operation is to seal the holes and cables together with sealant to protect the internal clean positive pressure environment.

[0004] Although such structures are easy to operate, in the specific application scenario of magnetic levitation blowers, such protective mechanisms are prone to micro-cracks due to the low-frequency vibrations generated by the machine's operation, as well as the long-term alternating stress on the bonding interface between the adhesive and the metal shell and cable sheath after curing. These micro-cracks gradually expand and eventually cause the adhesive layer to detach. Therefore, this issue urgently needs to be addressed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a magnetic levitation blower with a protective structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic levitation blower with a protective structure includes a body, in which a mounting frame is installed in a plurality of wire holes located inside the body. A plurality of support tubes are flexibly connected to the mounting frame through a rubber diaphragm. A plurality of flexible clamps are flexibly connected to one side of the support tubes. The outer wall of one end of the flexible clamps expands outward and is screwed with a threaded locking sleeve.

[0008] Each of the flexible clamps has a trigger frame on its inner wall. One end of the trigger frame has a long side and a rubber collar is wrapped around the adjacent trigger frame. The rubber collar is in a folded position under natural working conditions.

[0009] In addition, a preferred structure is that each of the flexible clamps has an expansion rubber pad at one end of its inner wall, and the bottom surface of the expansion rubber pad is compressed, causing the side surface of the pad to deform and extend outward.

[0010] In addition, the preferred structure is that the trigger frame is T-shaped, the vertical section of the frame is connected to the inner wall of the flexible clamp, and one end of the horizontal section is a short side and the other end is a long side, with a stop block at the end of the long side.

[0011] Furthermore, in a preferred configuration, a cavity is formed between the long side and the inner wall of the flexible clamp to accommodate a rubber collar. A spring is embedded in the inner wall of the rubber collar, and in its natural state, the spring is in a pre-bent shape.

[0012] In addition, a preferred structure is that one end of the rubber collar is provided with a barrier groove for contacting the outer wall of the cable.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the cable can be independently inserted into the support tube, and the flexible clamp and sealing mechanism are stably contacted with the cable by rotating the threaded locking sleeve, and the rubber collar is simultaneously triggered to be fitted onto the cable. The rubber material is used to form a movable sealing structure, which effectively improves the sealing effect and stability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4A magnetic levitation blower with a protective structure includes a body 1, multiple cable holes inside the body 1 for cable routing, and mounting frames 2 installed in each cable hole. Multiple support tubes 3 are flexibly connected to the mounting frames 2 through rubber diaphragms 5. Multiple flexible clamping plates 4 are flexibly connected to one side of the support tubes 3. The flexible clamping plates 4 can be deformed and bent to a certain extent at their connection base points, and the outer wall of one end of the flexible clamping plate 4 expands outward and is screwed with a threaded locking sleeve 6.

[0022] Each flexible clamp 4 has an expansion rubber pad 41 on one side of its inner wall. After the bottom surface of the expansion rubber pad 41 is squeezed, the side of the pad body deforms and extends outward.

[0023] A trigger frame 8 is provided on the other side of the inner wall of the flexible clamping plate 4. The trigger frame 8 is T-shaped and has steel bars 81 embedded inside. The steel bars 81 make the trigger frame 8 rigid. The vertical section of the frame is connected to the inner wall of the flexible clamping plate 4, and one end of the horizontal section is the short side and the other end is the long side. A stop block 82 is provided at the end of the long side, and a rubber collar 83 is wrapped around the adjacent trigger frame 8. The rubber collar 83 is in a folded position under natural working conditions.

[0024] A cavity is formed between the long side and the inner wall of the flexible clamp 4 to install the rubber collar 83. The inner wall of the rubber collar 83 is fitted with a spring 85. In its natural state, the spring 85 is in a pre-bent state.

[0025] One end of the rubber collar 83 is provided with a barrier groove 84, which is used to contact the outer wall of the cable.

[0026] In this embodiment, the cable in the corresponding compartment (area) is passed through the support pipe 3, and the outer wall of the flexible clamp 4 expands outward by rotating the threaded locking sleeve 6. As the threaded locking sleeve 6 moves, the flexible clamp 4 generates inward compression, which drives the flexible clamp 4 to compress the outer wall of the cable passing through it. Subsequently, the expansion rubber pad 41 (preferably EPDM rubber) is deformed and expanded by the compression, thereby extending outward and contacting the adjacent expansion rubber pad 41 to form a stable sealing structure attached to the outer wall of the cable.

[0027] Next, the short side of the trigger frame 8 is compressed, and the long side is driven to rotate by the internal steel bar 81 with the middle as the base point. This causes the folded rubber sleeve 83 to be released by the spring 85 and quickly unfold. In its natural state, the rubber sleeve 83 is expanded by multiple trigger frames 8. When the flexible clamp 3 contracts inward, the rubber sleeve 83 is released by elastic force, and one end is separated from the long side and attached to the outer wall of the cable, while the other end is hooked on the stop block 82, forming a double sealing structure.

[0028] In its natural state, each support tube 3 has a plug 7 connected to its inner wall by threads to provide a sealing function. The installation function of the support tube 3 at the corresponding position can be solved by removing the plug 7.

[0029] In addition, it should be noted that the body 1, namely the magnetic levitation blower body, has interconnected holes in the blower compartment, inverter cabinet, main control system and sensor compartment, etc., and the mounting frame 2 mechanism is installed in each hole to run the corresponding cables.

[0030] The specific operating principles and structures of the magnetic levitation blower, which are not explained in detail above, are common knowledge to those skilled in the art and will not be explained further.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
