Description

Technical Field

[0001] The present application relates to the technical field of fans, and particularly to a simple maintenance structure for a regenerative fan. Background Art

[0002] The regenerative fan is designed according to the regenerative principle. The blades passing through the air inlet suck in the air and apply centrifugal force to accelerate the air forward and outward; the regenerative principle means that the air is pressed back by the annular housing to the bottom of the next blade and is thrown out again, and some pressure is increased with each regeneration.

[0003] In the existing regenerative fans, the rotor is mostly of an integral structure. However, when the regenerative fan is used for a long time, it needs to be maintained regularly. At present, when maintaining the fan in the market, the rotor is inconvenient to operate during disassembly and installation, and the efficiency during disassembly and installation is relatively low. Summary of the Utility Model

[0004] In order to improve the problem of inconvenient maintenance of the rotor of the existing regenerative fan, the present application provides a simple maintenance structure for the regenerative fan.

[0005] The present application provides a simple maintenance structure for a regenerative fan, including a bracket and a fan housing installed on the top of the bracket. A rotor mechanism is provided on the inner wall of the fan housing. The rotor mechanism includes two mounting frames in a cross structure, and the same rotating shaft is rotatably connected between the two mounting frames. The outer wall of the rotating shaft is fixedly connected with rotating blades. Four connecting seats are fixedly connected between the two mounting frames. Four driving components are provided inside both mounting frames, and the four driving components are respectively connected through the four connecting seats.

[0006] With the above structure, the bracket is convenient for supporting and installing the fan. The two mounting frames in the rotor mechanism are convenient for installing the rotating shaft and the rotating blades. The mounting frames connect the rotating shaft and the rotating blades into an integral structure. When the rotor needs to be maintained, the two mounting frames are directly removed from the fan housing. The driving components are convenient for quickly disassembling and installing the mounting frames, and the connecting seats are convenient for connecting the two mounting frames.

[0007] The rotor mechanism includes eight fixing components matching the mounting frames. The fixing components include U-shaped seats fixedly connected to the inner wall of the fan housing, and limiting openings are provided on the outer walls of both sides of the U-shaped seats.

[0008] With the above structure, through the cooperation between the U-shaped seats and the mounting frames in the fixing components, it is convenient to fix the mounting frames in the fan housing.

[0009] The driving component includes a bidirectional screw rotatably installed on the inner walls of both sides of the installation cavity, and two symmetrically arranged threaded sleeves are screwed on the outer wall of the bidirectional screw.

[0010] With the above structure, the installation cavity is provided to facilitate the installation of the bidirectional screw. When the bidirectional screw rotates, it directly drives the two threaded sleeves to move towards or away from each other.

[0011] Two symmetrically arranged sliding seats are slidably connected to the inner wall of the installation cavity, and support plates are rotatably connected to the outer walls of the opposite sides of the two sliding seats.

[0012] With the above structure, the installation cavity is provided to facilitate the sliding installation of the two sliding seats, and the support plate is provided to facilitate driving the sliding seat to move.

[0013] Openings are formed in the inner walls on both sides of the installation cavity, and limit seats are slidably connected to the inner walls of the two openings. The specifications of the limit seats match the specifications of the limit openings.

[0014] With the above structure, by inserting the limit seat into the limit opening, it is convenient to fix the mounting frame in the U-shaped seat.

[0015] The two sliding seats are respectively fixedly connected to the two limit seats, and a connecting shaft is rotatably connected to the inner wall of the connecting seat.

[0016] With the above structure, the movement of the threaded sleeve drives the support plate to drive the sliding seat to move. When the sliding seat moves, it is convenient to directly drive the limit seat to move. The two connecting shafts are provided to facilitate connecting the two bidirectional screws on the opposite sides of the mounting frame.

[0017] The bidirectional screws in the two installation cavities on the opposite sides of the two mounting frames are both fixedly connected to the connecting shaft. One side outer wall of one mounting frame is rotatably connected with four rotating parts, and one end of the transmission shaft of the rotating part is fixedly connected to the bidirectional screw.

[0018] With the above structure, the rotating part is provided to facilitate directly driving the bidirectional screw to rotate.

[0019] An inspection opening is formed in one side outer wall of the fan housing, and a machine cover is fixedly connected to the inner wall of the inspection opening. An air inlet is formed in one side outer wall of the machine cover, and a filter screen is fixedly connected to the inner wall of the air inlet.

[0020] With the above structure, the detachable machine cover is provided to facilitate the maintenance of the rotor mechanism in the fan housing, and the filter screen is provided to facilitate filtering the air entering the fan.

[0021] In summary, the beneficial effects of the present application are as follows:

[0022] 1. This application solves the problem that the existing fan rotor is inconvenient to disassemble and maintain by setting a rotor mechanism in the fan housing. The two mounting brackets in the rotor mechanism facilitate the installation of the rotating shaft and rotating blades of the fan. At the same time, the two mounting brackets are conveniently installed in the fan housing through the setting of the fixing components. When the rotating shaft and rotating blades are overhauled, they can be directly pulled out of the fan housing through the two mounting brackets, thus facilitating the maintenance and overhaul of the fan rotor.

[0023] 2. This application sets a plurality of adjustable limit seats on the mounting bracket. When the limit seat is inserted into the limit opening in the U-shaped seat, the mounting bracket can be fixed in the fan housing. The rotation of the bidirectional screw in the installation cavity cooperates with the cooperation between the threaded sleeve and the support plate, thus facilitating the adjustment of the position of the limit seat.

Detailed Description of the Invention

[0030] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings.

[0031] Please refer to Figures 1-3, A simple maintenance structure for a regeneration fan, including a bracket 1 and a fan housing 2 installed on the top of the bracket 1. The inner wall of the fan housing 2 is provided with a rotor mechanism 5. The rotor mechanism 5 includes two mounting frames 6 in a cross structure, and a same rotating shaft 7 is rotatably connected between the two mounting frames 6. The outer wall of the rotating shaft 7 is fixedly connected with rotating blades 8. Four connecting seats 10 are fixedly connected between the two mounting frames 6. Four driving components are respectively arranged inside the two mounting frames 6, and the four driving components are respectively connected through the four connecting seats 10.

[0032] During use, the setting of the bracket 1 facilitates the support and installation of the fan. The setting of the two mounting frames 6 in the rotor mechanism 5 facilitates the installation of the rotating shaft 7 and the rotating blades 8. The setting of the mounting frame 6 connects the rotating shaft 7 and the rotating blades 8 into an integral structure. When rotor maintenance is required, directly remove the two mounting frames 6 from the fan housing 2. The setting of the driving components facilitates the quick disassembly and assembly of the mounting frame 6, and the setting of the connecting seats 10 facilitates the connection of the two mounting frames 6.

[0033] Refer to Figures 3-4 , the rotor mechanism 5 includes eight fixing components 9 that match the mounting frame 6, and the fixing component 9 includes a U-shaped seat 12 fixedly connected to the inner wall of the fan housing 2. Limiting ports 13 are respectively opened on the outer walls of both sides of the U-shaped seat 12. Through the cooperation between the U-shaped seat 12 and the mounting frame 6 in the fixing component 9, it is convenient to fix the mounting frame 6 in the fan housing 2.

[0034] Refer to Figure 5 , the driving component includes a bidirectional screw 18 rotatably installed on the inner walls of both sides of the installation cavity 15, and two symmetrically arranged threaded sleeves 19 are screwed on the outer wall of the bidirectional screw 18. The setting of the installation cavity 15 facilitates the installation of the bidirectional screw 18. When the bidirectional screw 18 rotates, it directly drives the two threaded sleeves 19 to move towards or away from each other.

[0035] Refer to Figure 5 , two symmetrically arranged sliding seats 16 are slidably connected to the inner wall of the installation cavity 15, and support plates 20 are rotatably connected to the outer walls of the opposite sides of the two sliding seats 16. The setting of the installation cavity 15 facilitates the sliding installation of the two sliding seats 16, and the setting of the support plates 20 facilitates driving the sliding seats 16 to move.

[0036] Refer to Figure 5 , openings are respectively opened on the inner walls of both sides of the installation cavity, and limiting seats 14 are slidably connected to the inner walls of the two openings. The specifications of the limiting seats 14 match the specifications of the limiting ports 13. By inserting the limiting seats 14 into the limiting ports 13, it is convenient to fix the mounting frame 6 in the U-shaped seat 12.

[0037] Refer to Figure 5, two sliding seats 16 are respectively fixedly connected to two limiting seats 14. A connecting shaft 17 is rotatably connected to the inner wall of the connecting seat 10. The movement of the threaded sleeve 19 drives the support plate 20 to drive the sliding seat 16 to move. When the sliding seat 16 moves, it is convenient to directly drive the limiting seat 14 to move. The arrangement of the two connecting shafts 17 facilitates the connection of the two opposite lead screws 18 on the mounting bracket 6.

[0038] Referring to Figure 5 , the lead screws 18 in the two opposite mounting cavities 15 of the two mounting brackets 6 are both fixedly connected to the connecting shaft 17. One side outer wall of one mounting bracket 6 is rotatably connected with four rotating parts 11, and one end of the transmission shaft of the rotating part 11 is fixedly connected to the lead screw 18. The arrangement of the rotating part 11 facilitates directly driving the lead screw 18 to rotate.

[0039] Referring to Figure 2 , an inspection opening is provided on one side outer wall of the fan housing 2, and a machine cover 3 is fixedly connected to the inner wall of the inspection opening. An air inlet is provided on one side outer wall of the machine cover 3, and a filter screen 4 is fixedly connected to the inner wall of the air inlet. The arrangement of the detachable machine cover 3 facilitates the maintenance of the rotor mechanism 5 in the fan housing 2, and the arrangement of the filter screen 4 facilitates filtering the air entering the fan.

[0040] The implementation principle of this application is as follows: When in use, when it is necessary to maintain the rotor in the fan, first remove the machine cover 3 on the fan housing 2, and then rotate the rotating part 11 by sleeving a socket wrench. When the rotating part 11 rotates, it directly drives the lead screw 18 to rotate. The lead screws 18 in the two corresponding mounting cavities 15 on the mounting bracket 6 are connected through the connecting shaft 17, so that it is convenient for the two lead screws 18 to rotate synchronously. When the lead screw 18 rotates, it directly drives the two threaded sleeves 19 on it to move towards or away from each other. When the two threaded sleeves 19 move away from each other, they directly pull the limiting seat 14 into the mounting cavity 15 through the support plate 20. When the limiting seat 14 is far away from the limiting opening 13 on the U-shaped seat 12, the mounting bracket 6 can be removed from the fan housing 2.

[0041] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
