Description

Technical Field

[0001] This invention relates to the field of axial flow fan technology, and in particular to an axial flow fan for cold storage based on an automatic temperature control module. Background Technology

[0002] An axial flow fan is one in which the airflow is in the same direction as the fan blades' axis, such as an electric fan or the outdoor unit fan of an air conditioner. It's called "axial flow" because the gas flows parallel to the fan's axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure; therefore, they are often used in warehouses. However, because cold storage requires maintaining a consistently low temperature, automatic temperature control systems are often used to manage the operation of these axial flow fans.

[0003] In existing technologies, the blades of axial flow fans are generally fixedly mounted on the rotating shaft of the motor, and the number of blades is also fixed. In actual use, the blades often break after long-term use. After the blades break, professionals need to use specialized equipment to disassemble the entire axial flow fan to replace the blades. Replacing the blades is time-consuming and labor-intensive. At the same time, axial flow fans used in cold storage are generally fixedly installed, so fixed axial flow fans cannot increase airflow at multiple angles. When it is necessary to increase airflow at different locations, it can only be achieved by increasing the number of axial flow fans, which increases the cost of use. Therefore, there is a need for an axial flow fan for cold storage based on an automatic temperature control module to meet people's needs. Summary of the Invention

[0004] The purpose of this invention is to provide an axial flow fan for cold storage based on an automatic temperature control module, in order to solve the problem mentioned in the background art that when the fan blades of an axial flow fan are broken or damaged, the entire axial flow fan needs to be disassembled for replacement, which is not only time-consuming and laborious, but also delays normal use. At the same time, existing axial flow fans cannot be adjusted to different positions according to actual usage conditions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an axial flow fan for cold storage based on an automatic temperature control module, comprising a cold storage, an axial fan duct on the cold storage, a drive motor on the axial fan duct, a drive shaft on the drive motor, a platform on the drive shaft, fan blades on the platform, a support block on the platform, a circular fixed platform on the support block, a rotating disk rotatably mounted on the circular fixed platform, a connecting rod rotatably mounted on the rotating disk, a T-shaped block rotatably mounted on the connecting rod, a retaining shaft mounted on the T-shaped block, a connecting block mounted on the fan blades, and an installation hole on the connecting block, the retaining shaft being movably mounted in the installation hole.

[0006] Preferably, a gear is mounted on the drive shaft, and a gear ring meshes with the gear, with the gear ring mounted on the shaft fan pipe.

[0007] Preferably, a retaining rod is installed on the circular fixed platform, and a positioning hole is provided on the rotating disk, with the retaining rod slidably installed in the positioning hole.

[0008] Preferably, a rotating shaft is installed on the rotating disk, a rotating shaft is installed on the T-block, and two rotating holes are opened on the connecting rod. The rotating shaft and the rotating shaft are respectively rotatably installed in the two connecting rods.

[0009] Preferably, the circular fixing platform has a T-shaped hole, and the T-shaped block is slidably installed in the T-shaped hole.

[0010] Preferably, a drive handle is installed on the rotating disk, a plug rod is sleeved on the drive handle, and a plug hole is opened on the support block, with the plug rod movably installed in the plug hole.

[0011] Preferably, a fixing block is slidably mounted on the gear ring, a retaining ring is mounted on one side of the fixing block and is rotatably mounted on the drive shaft, and an mounting plate is mounted on the other side of the fixing block and is mounted on the drive motor.

[0012] Preferably, a limiting slider is installed on the fixing block, and a limiting groove is formed on the toothed ring, with the limiting slider slidably installed in the limiting groove.

[0013] The beneficial effects of this invention are:

[0014] In this invention, the structure consisting of a circular fixed platform, a rotating disk, a connecting rod, a T-block, a retaining shaft, and mounting holes allows for easy replacement of broken fan blades in axial flow fans. This is achieved by simply pulling out the connecting rod, rotating the drive handle to move the rotating disk, which in turn moves the connecting rod, which in turn moves the T-block, which in turn moves the retaining shaft out of the mounting hole on the connecting block. The broken fan blades can then be removed for replacement and maintenance. Furthermore, the number of fan blades can be adjusted according to actual usage, avoiding the need for specialized personnel to disassemble the entire axial flow fan and replace the broken blades, which is time-consuming and labor-intensive.

[0015] In this invention, by setting up a gear ring, gears, limiting sliders and fixing blocks, when it is necessary to use axial flow fans to change the airflow in different positions in the cold storage, it is only necessary to start the drive motor. The drive motor drives the drive shaft to rotate, and the drive shaft drives the gear to rotate on the gear ring, thereby quickly changing the position of air entry. This avoids the need to increase the number of axial flow fans when it is necessary to increase the airflow in different positions, which would increase the cost of use. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Reference Figure 1-6An axial flow fan for cold storage based on an automatic temperature control module includes a cold storage 1, an axial fan pipe 2 on the cold storage 1, a drive motor 3 on the axial fan pipe 2, a drive shaft 4 on the drive motor 3, a platform 5 on the drive shaft 4, fan blades 6 on the platform 5, a support block 14 on the platform 5, a circular fixed platform 15 on the support block 14, a rotating disk 16 rotatably mounted on the circular fixed platform 15, and a connecting rod 23 rotatably mounted on the rotating disk 16. A T-block 25 is movably installed, and a retaining shaft 24 is installed on the T-block 25. A connecting block 17 is installed on the fan blade 6, and a mounting hole 30 is opened on the connecting block 17. The retaining shaft 24 is movably installed in the mounting hole 30. The connecting rod 23 is moved by the rotating disk 16. The movement of the connecting rod 23 causes the T-block 25 to move. The movement of the T-block 25 causes the retaining shaft 24 to be withdrawn from the mounting hole 30 on the connecting block 17. This allows for quick maintenance of the fan blade 6 and changes in the number of fan blades 6.

[0025] Reference Figure 1-3 In this invention, a gear 8 is mounted on the drive shaft 4, and a gear ring 7 meshes with the gear 8. The gear ring 7 is mounted on the shaft fan pipe 2. The drive shaft 4 drives the gear 8 to rotate on the gear ring 7, thereby quickly changing the position of the air intake.

[0026] Reference Figure 5-6 In this invention, a retaining rod 22 is installed on the circular fixed platform 15, and a positioning hole 21 is provided on the rotating disk 16. The retaining rod 22 is slidably installed in the positioning hole 21. By rotating the retaining rod 22 in the positioning hole 21, the rotating disk 16 will not fall off when it moves in the circular fixed platform 15.

[0027] Reference Figure 5-6 In this invention, a rotating shaft 27 is installed on the rotating disk 16, a rotating shaft 28 is installed on the T-block 25, and two rotating holes 29 are opened on the connecting rod 23. The rotating shaft 27 and the rotating shaft 28 are respectively rotatably installed in the two connecting rods 23. By rotating the rotating shaft 27 on the rotating disk 16 and the rotating shaft 28 on the T-block 25 in the rotating holes 29 on the connecting rods 23, it is convenient to convert the rotation of the rotating disk 16 into the back-and-forth movement of the T-block 25.

[0028] Reference Figure 6 In this invention, a T-shaped hole 26 is provided on the circular fixed platform 15, and a T-shaped block 25 is slidably installed in the T-shaped hole 26. The movement of the T-shaped block 25 in the T-shaped hole 26 facilitates the movement of the fixed shaft 24.

[0029] Reference Figure 5In this invention, a drive handle 18 is installed on the rotating disk 16, and a plug rod 19 is sleeved on the drive handle 18. A plug hole 20 is opened on the support block 14, and the plug rod 19 is movably installed in the plug hole 20. By moving the plug rod 19 on the drive handle 18 in the plug hole 20 on the support block 14, the installed fan blade 6 can be quickly fixed.

[0030] Reference Figure 2-3 In this invention, a fixing block 11 is slidably mounted on the toothed ring 7, and a retaining ring 12 is mounted on one side of the fixing block 11. The retaining ring 12 is rotatably mounted on the drive shaft 4. An mounting plate 13 is mounted on the other side of the fixing block 11. The mounting plate 13 is mounted on the drive motor 3. The drive motor 3 is fixed by the retaining ring 12 on the fixing block 11 and the mounting plate 13 on the fixing block 11, so that the drive motor 3 will not fall off when it moves.

[0031] Reference Figure 3 In this invention, a limiting slider 9 is installed on the fixed block 11, and a limiting groove 10 is opened on the toothed ring 7. The limiting slider 9 is slidably installed in the limiting groove 10. By moving the limiting slider 9 in the limiting groove 10 on the toothed ring 7, the axial flow fan will not deviate when it moves.

[0032] Working principle of this invention:

[0033] When the axial flow fan of the cold storage unit using the automatic temperature control module ventilates the cold storage 1, the automatic temperature control module ensures that the air drawn into the cold storage 1 meets the required standards. Simultaneously, if the fan blade 6 of the axial flow fan is found to be damaged, the insertion rod 19 in the insertion hole 20 on the support block 14 is manually pulled out. Then, the drive handle 18 is manually rotated. The drive handle 18 moves, causing the rotating disk 16 to rotate on the circular fixed platform 15. The movement of the rotating disk 16 moves the rotating shaft 27, which in turn moves the connecting rod 23. The movement of the connecting rod 23 moves the rotating hole 29, which in turn moves the rotating shaft 28. The movement of the rotating shaft 28 causes the T-block 25 to move backward within the T-hole 26 on the rotating disk 16. The drive motor 3 moves the fixed shaft 24 out of the mounting hole 30 on the connecting block 17, and then the fan blade 6 is manually pulled out for replacement and maintenance. The number of fan blades 6 can also be changed according to the actual use, avoiding the need for professional personnel to use special equipment to disassemble the entire axial flow fan and replace the fan blades 6 after they break. Replacing the fan blades 6 is time-consuming and laborious. At the same time, the drive motor 3 drives the drive shaft 4 to rotate, and the drive shaft 4 drives the gear 8 to rotate on the gear ring 7. Meanwhile, the limit slider 9 on the fixed block 11 moves in the limit groove 10 on the gear ring 7, so that the position of air entry can be quickly changed. This avoids the need to increase the number of axial flow fans when it is necessary to increase the airflow at different positions, which would increase the cost of use.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
