Abstract
Description
Technical Field
[0001] This utility model relates to the field of installation structure technology, and more specifically to a quick installation structure for a fan with a volute casing. Background Technology
[0002] In existing fan installation structures, especially those involving volute fans, the fan is typically connected to the equipment casing using direct bolt fixing or flange connections. While these traditional installation methods are simple in structure, they have several shortcomings in practical applications: First, traditional installation methods typically require a large operating space for tightening and loosening bolts, which is extremely inconvenient in situations with limited space or compact equipment structures, increasing the difficulty of installation and maintenance. Second, the vibrations generated by the fan during operation are directly transmitted to the casing through rigid connections, leading to increased overall equipment noise, affecting user comfort, and potentially shortening the lifespan of the fan and related components.
[0003] Furthermore, existing technologies lack effective quick-assembly and disassembly designs. Each time a wind turbine is maintained or replaced, multiple connecting components often need to be disassembled, and even surrounding structures may need to be moved or removed. This is not only time-consuming and labor-intensive but also increases maintenance costs. The inefficiency of traditional structures is particularly prominent in applications requiring frequent wind turbine maintenance or replacement. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a quick-installation structure for a fan with a volute casing. This quick-installation structure for a fan with a volute casing achieves rapid installation and disassembly of the fan through a plug-in design and a split-type sealing plate structure, and effectively isolates vibration by utilizing an elastic damping ring, thereby improving installation efficiency and user experience.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A quick-installation structure for a fan with a volute casing includes a housing and a fan. A connecting plate is provided at the air outlet of the fan, and an elastic damping ring is fitted on the connecting plate. An air outlet is provided inside the housing, and a connecting assembly is provided at the air outlet. The connecting assembly includes a plug-in plate and a sealing plate. The plug-in plate is detachably installed at the air outlet and has a slot. The connecting plate is inserted into the slot. The sealing plate is detachably installed on the housing and is located at the opening of the slot to close the slot. The elastic damping ring contacts and abuts against the plug-in plate and the sealing plate respectively.
[0006] Furthermore, the elastic damping ring includes a rubber ring, which includes a connecting part and an elastic compensation part. The connecting part is provided with a connecting groove, and the connecting plate is inserted into the connecting groove to achieve a fitting connection with the rubber ring. The elastic compensation part is provided with a plurality of compensation protrusions, which can contact and abut against the plug plate and the sealing plate to undergo deformation.
[0007] Furthermore, the plug-in plate is provided with a plurality of first through holes, and the air vent of the housing is provided with a plurality of mounting holes. A first connecting bolt is provided in the first through hole, and the first connecting bolt passes through the mounting hole and the first through hole and is fitted with a first nut.
[0008] Furthermore, the sealing plate is provided with a plurality of second through holes, and a second connecting bolt is provided in the second through hole. The second connecting bolt passes through the mounting hole and the second through hole and is fitted with a second nut.
[0009] Furthermore, the plug-in plate is provided with L-shaped plates on both sides, and a bent plate is provided on the side adjacent to the two L-shaped plates. The space between the two L-shaped plates and the bent plate forms a slot.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Significantly improved ease of installation: Through the plug-in structure and split sealing plate design, the fan can achieve a quick installation method of "plug and fix", which greatly shortens the assembly time and is especially suitable for occasions with limited space or frequent maintenance.

The sealing plate 5 is detachably installed on the housing 1 and is located at the opening of the slot 403 to seal the slot 403. The elastic damping ring 3 contacts and abuts against the plug-in plate 4 and the sealing plate 5 respectively.
[0020] Preferably, the elastic damping ring 3 includes a rubber ring, the rubber ring includes a connecting part and an elastic compensation part, the connecting part is provided with a connecting groove 301, the connecting plate is inserted into the connecting groove 301 to achieve a fitting connection with the rubber ring, and the elastic compensation part is provided with a plurality of compensation protrusions 302, which can contact and abut against the plug plate 4 and the sealing plate 5 to undergo deformation; Specifically, the elastic damping ring 3 is made of rubber and includes a connecting part and an elastic compensation part. The connecting part has a connecting groove 301 for fitting onto the connecting plate of the fan 2. The elastic compensation part has multiple compensation protruding rings 302, which, after being inserted into the slot 403, come into close contact with the plug plate 4 and the sealing plate 5 and deform to form an interference fit. The compression deformation of the elastic body achieves a flexible connection between the fan 2 and the casing 1, effectively absorbing the vibration of the fan 2 during operation and reducing noise transmission. The design of the compensation protruding rings 302 enhances the sealing and pre-tightening force, preventing the fan 2 from loosening during operation and improving installation stability.
[0021] Preferably, the plug-in plate 4 is provided with a plurality of first through holes, and the air vent 8 of the housing 1 is provided with a plurality of mounting holes. A first connecting bolt is provided in the first through hole.

Specifically, the plug plate 4 is fixed to the air outlet 8 of the housing 1 with bolts to form a slot 403; the sealing plate 5 is independently installed at the opening of the slot 403 and the elastic damping ring 3 is pressed with bolts; the split design facilitates installation and disassembly in a narrow space, solving the limitation of the traditional integrated structure on the operating space. As a detachable component, the sealing plate 5 facilitates the later maintenance or replacement of the fan 2 without dismantling the entire housing 1 structure.
[0022] Preferably, L-shaped plates 401 are provided on both sides of the plug plate 4, and a bent plate 402 is provided on the side adjacent to the L-shaped plates 401 on both sides, and a slot 403 is formed between the L-shaped plates 401 and the bent plate 402 on both sides.

This structural design makes the overall structure simple and easy to process. The slot 403 has good guiding properties, which makes it easy for the fan 2 connecting plate to be quickly inserted and positioned. In addition, it works with the elastic damping ring 3 to form multiple contact surfaces, which enhances the rigidity and sealing performance of the overall structure.
