Description

Technical Field

[0001] This application relates to the field of industrial fan technology, and in particular to a highly safe industrial fan. Background Technology

[0002] Industrial fans are widely used in large spaces where improved air quality and human comfort are required, such as industrial plants, logistics and warehousing centers, large workshops, stadiums, exhibition halls, waiting halls (for trains and planes), shopping malls and supermarkets, and large-scale farms. They are commonly used to solve ventilation and cooling problems in large spaces.

[0003] Common industrial fan connectors often require several holes. Each fan blade is threaded through these holes and fixed to the connector, which is then fixed to the mounting base. Bolts are used to secure the connector to the mounting base through these holes. Stress concentration occurs around the holes, especially under high-cycle fatigue loads. These areas are potential crack initiation points. Too many holes in the connectors increase the risk of damage to the connectors after prolonged use of the industrial fan, requiring frequent maintenance and inspection, thus reducing the safety of the industrial fan. Utility Model Content

[0004] To improve the safety of industrial fans, this application provides a highly safe industrial fan.

[0005] This application provides a highly safe industrial fan, which adopts the following technical solution:

[0006] A high-safety industrial fan includes a mounting base and several connectors. Each connector has fan blades. The fan also includes several limiting components, each corresponding to one of the connectors. The connectors are mounted on the mounting base via the limiting components. Each limiting component includes a first limiting block and a second limiting block. The first limiting block is mounted on the mounting base, and the second limiting block is located on the side of the first limiting block away from the mounting base. Both the first and second limiting blocks have connecting holes for the connectors to pass through. The first limiting block has a locking block, and the connectors have locking grooves for the locking block to engage.

[0007] By adopting the above technical solution, when an industrial fan needs to be installed, the first limiting block is set on the mounting base. When installing the connector, the slot on the connector is engaged with the locking block on the first limiting block. The second limiting block is then installed. The first and second limiting blocks ensure that the connector is firmly fixed during operation and is not easily detached. The limiting components limit the connector, eliminating the need to fix the connector to the mounting base by drilling threaded holes. This reduces maintenance and inspection, makes the connector less prone to damage, and improves the safety of the industrial fan.

[0008] Optionally, the second limiting block is provided with an insert, and the connector has a slot, through which the insert passes and engages with the slot.

[0009] By adopting the above technical solution, the robustness of the connector installation and limiting components is further improved through the insertion blocks and slots.

[0010] Optionally, the mounting base is provided with a plurality of first through holes, the first limiting block is provided with a plurality of second through holes, and the second limiting block is provided with a plurality of threaded holes, wherein the plurality of threaded holes correspond one-to-one with the second through holes, and further includes a first screw, wherein the first screw passes through the first through holes and the second through holes and is threadedly connected to the threaded holes.

[0011] By adopting the above technical solution, the fastener is fixed to the mounting base by the first screw, which makes the second limiting block and the first limiting block firmly installed, and each connecting part can be disassembled and replaced individually.

[0012] Optionally, the bottom of the mounting base is provided with several grooves, which are provided for the first limiting block to receive.

[0013] By adopting the above technical solution, the groove facilitates the installation and positioning of the first limiting block, making the positioning of the first limiting block convenient.

[0014] Optionally, the end of the first screw protrudes from the surface of the threaded hole, and a first nut is threaded onto the first screw, with the first nut abutting against the surface of the second limiting block.

[0015] By adopting the above technical solution, the first nut is threadedly connected to the first screw, and at the same time, the first nut abuts against the surface of the second limiting block. The nut further improves the firmness of the limiting component. Through the threaded hole on the second limiting block and the nut, the limiting component is not easy to loosen.

[0016] Optionally, the fan blade has an installation groove for the connector to pass through, the fan blade has several fixing holes that penetrate the fan blade, the connector has an installation hole, and also includes a second screw and a second nut. The second screw passes through the fixing hole and the installation hole, and the second nut is threadedly connected to the second screw.

[0017] By adopting the above technical solution, the fan blade is firmly fixed to the connector by the second screw and the second nut.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The slot on the connector engages with the block on the first limit block, ensuring that the connector is securely fixed during operation, preventing damage to the connector and improving the safety of the industrial fan;

[0020] 2. The insert and slot improve the stability of the connector when it is mounted on the limiting assembly;

[0021] 3. The groove facilitates the positioning of the first limiting block. Attached Figure Description

Both the first and second limiting blocks 41 and 42 have connecting holes 32 for the connecting parts 2 to pass through. A locking block 33 is fixed to the first limiting block 41, and a locking groove 34 is formed on the connecting parts 2 for the locking block 33 to engage. An insert block 35 is fixed to the second limiting block 42, and a slot 36 is formed on the connecting parts 2, through which the insert block 35 passes and engages with the slot 36.

[0030] Reference Figure 2 , Figure 3 , Figure 4 The mounting base 1 has several first through holes 51, and the first limiting block 41 has several second through holes 52. The second limiting block 42 has several threaded holes 53, which correspond one-to-one with the second through holes 52. The high-safety industrial fan also includes a first screw 6, which passes through the first through holes 51 and the second through holes 52 and is threaded into the threaded hole 53.
