Description

Technical Field

[0001] This utility model relates to the field of pipe connection device technology, and in particular to a fastening device for flexible connection pipes of fans that improves connection stability. Background Technology

[0002] A flexible connecting pipe for fans is a flexible connection accessory used to connect fans and pipelines. Its main functions are noise reduction and compensation for thermal deformation of pipelines. It is usually installed at the inlet and outlet of the fan to achieve smooth operation of the fan and stability of the system.

[0003] As the service life increases, the flexible connecting pipe of the wind turbine will age and deform, resulting in a decrease in its power transmission efficiency, which in turn affects the operating efficiency of the wind turbine. It is necessary to inspect and replace it. The existing flexible hose connection method of wind turbines is mostly bolt fixed connection, which is inconvenient to disassemble and affects the work efficiency of maintenance personnel. Utility Model Content

[0004] This utility model discloses a fastening device for flexible connecting pipes of wind turbines to improve connection stability, aiming to solve the technical problem that the inconvenience of disassembling existing devices affects the work efficiency of maintenance personnel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fastening device for a flexible connecting pipe of a wind turbine to improve connection stability includes a connecting base. The outer wall of the connecting base has a sliding groove, and a detachable module is provided inside the sliding groove. One side of the outer wall of the connecting base has an installation cavity, and an auxiliary stabilizing module and a sealing ring are provided inside the installation cavity. The sealing ring is located on one side of the auxiliary stabilizing module.

[0007] By incorporating a connecting base, mounting cavity, sliding groove, sealing ring, detachable module, and auxiliary stabilization module, the sealing ring enhances the equipment's sealing performance during use, preventing gas leakage from the gap between the fan hose and the connecting base, thus improving fan efficiency. The detachable module allows for quick replacement of the fan hose, improving the work efficiency of maintenance personnel. The auxiliary stabilization module enhances the stability of the fan hose during operation.

[0008] In a preferred embodiment, the detachable module includes a mounting base, which is movably connected to the interior of a sliding groove. Rubber pads are fixedly connected to the outer walls of both sides of the mounting base, with the outer walls of the two rubber pads contacting the inner walls of the sliding groove. A mounting groove is formed on one outer wall of the mounting base, and multiple elastic plates are evenly spaced on the inner wall of the mounting groove. A common fan hose is provided on the outer wall of each of the multiple elastic plates, and the fan hose is located inside the mounting cavity. A limiting frame is fixedly connected to the top of the mounting base, and a pull rod is fixedly connected to the top of the limiting frame. The inner wall of the limiting frame contacts the outer wall of the connecting base. A fixing base is fixedly connected to the bottom of the connecting base. Mounting rods are fixedly connected to the outer walls of both sides of the fixing base. Limiting plates are movably connected to the outer walls of both mounting rods, and both limiting plates are engaged with the limiting frame. Tension springs are sleeved on the outer walls of both mounting rods, with one end of each tension spring fixedly connected to the outer walls of both sides of the fixing base, and the other end of each tension spring fixedly connected to the inner wall of one side of each limiting plate.

[0009] By incorporating a detachable module, operators can easily replace the fan hose, thereby improving the efficiency of hose replacement and enhancing the overall performance of the device. Furthermore, the detachable module allows for easy removal and replacement of the fan hose from the outside of the equipment, preventing damage from forceful disassembly and improving the device's practicality. Additionally, the detachable module provides a snap-fit ​​fixation, ensuring the stability of the fan hose installation and guaranteeing safe operation.

[0010] In a preferred embodiment, the auxiliary stabilization module includes a circular frame located inside the mounting cavity. Two annular frames are fixedly connected to the outer wall of the circular frame. Both annular frames have buffer pads inside, and one annular frame has a limiting component on one side of its outer wall. A snap-fit ​​seat is fixedly connected to one side of the outer wall of the other annular frame. An I-shaped seat is movably connected to one side of the outer wall of the snap-fit ​​seat, and arc-shaped rubber blocks are provided on the inner walls of opposite sides of the I-shaped seat. The outer walls of both arc-shaped rubber blocks are in contact with the outer wall of the fan hose.

[0011] By incorporating an auxiliary stabilization module, the hose can be prevented from deforming due to airflow impact and its own vibration during fan operation. This module limits excessive deformation, maintains the hose's shape and size stability, and improves the stability of the equipment during operation. Furthermore, the clamping seat can be replaced according to different tooth diameters of fan hoses, further enhancing the equipment's performance.

[0012] As can be seen from the above, the detachable module of the fastening device for the flexible connecting pipe of the fan provided by this utility model, which improves the connection stability, allows the operator to easily replace the fan hose, thereby improving the replacement efficiency and the effectiveness of the device. Furthermore, when replacing the fan hose, the operator can disassemble and replace it from the outside of the device, making the operation convenient and avoiding damage caused by violent disassembly, thus improving the practicality of the device. At the same time, the detachable module can be snapped in place to ensure the stability of the fan hose installation and the safety of subsequent use. Attached Figure Description

Rubber pads 204 are fixedly connected to the outer walls of both sides of the mounting base 203, with the outer walls of the two rubber pads 204 respectively contacting the inner wall of the sliding groove 5. A mounting groove is formed on one outer wall of the mounting base 203, and multiple elastic pieces 209 are evenly installed on the inner wall of the mounting groove. The outer walls of the multiple elastic pieces 209 are provided with the same fan hose 3, which is located inside the mounting cavity 6. A limiting frame 201 is fixedly connected to the top of the mounting base 203, and a limiting frame 201 is fixedly connected to the top of the limiting frame 201. A pull rod 202 is provided, and the inner wall of the limiting frame 201 is in contact with the outer wall of the connecting base 1.

Tension springs 207 are sleeved on the outer walls of the two mounting rods 208. One end of the two tension springs 207 is fixedly connected to the outer walls of both sides of the fixed seat 206, and the other end of the tension springs 207 is fixedly connected to the inner wall of one side of the two limiting plates 205.

[0022] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the auxiliary stabilization module 7 includes a circular frame 701 located inside the mounting cavity 6. Two annular frames 702 are fixedly connected to the outer wall of the circular frame 701.
