Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a high-efficiency semi-open axial flow fan. Background Art

[0002] A high-efficiency semi-open axial flow fan is a compact, rationally designed axial flow fan that significantly increases air volume and efficiency while maintaining consistent wind pressure, while significantly reducing noise. Its blades are uniquely designed, typically consisting of a main wing, with roots and tips positioned at either end. The number of blades is optimally configured, and the operating principle of a high-efficiency semi-open axial flow fan is based on Newton's third law of action and reaction. When the motor drives the impeller to rotate, the blades draw air in through the air inlet and, propelled by the blades, expel it axially. This process not only energizes the air but also allows it to flow out at a higher velocity, ensuring efficient air flow.

[0003] In the existing high-efficiency semi-open axial flow fan, it usually includes a fixing frame, a support frame, a motor, a mounting frame, fan blades and a fan frame, wherein the mounting frame is arranged inside the fixing frame, and the motor is installed on the mounting frame. The output end of the motor is fixedly connected to a rotating rod, and the rotating rod and one side of the fan frame are connected by multiple bolts. There are multiple fan blades, and multiple fan blades are welded to the outer wall of the fan frame. However, during the use of the existing setting, when the fan frame needs to be maintained, multiple bolts need to be removed. When the fan frame is installed, the fan frame needs to be reinstalled on the rotating rod, and it needs to be manually positioned to the installation bolt hole. Then, the fan frame needs to be manually supported, and then the fan frame and the rotating rod need to be fixed with bolts. This method makes the overall maintenance work more cumbersome. Summary of the Invention

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-efficiency semi-open axial flow fan.

[0012] The utility model has the following beneficial effects:

[0013] 1. Compared with the prior art, this high-efficiency semi-open axial flow fan, by providing a limit rod and a spring, can allow one side of the driving device to pass through the fan body when in use. During this process, one side of the driving device will contact the side of the two limit rods set in an arc shape, and the two limit rods will be squeezed by the driving device to make the two limit rods move toward the inside of the two movable grooves. During this movement, the springs will be compressed until one side of the driving device completely passes through the fan body. At this time, the two limit rods will pop out due to the force of the springs, and the position of the fan body can be positioned by the two limit rods so that it will not deviate during installation. It is then fixed by bolts two and three. When the fan body is disassembled, the bolts can be removed and the two limit rods can be moved back in the direction of the two movable grooves. The overall operation is simple, making maintenance of the fan body more convenient.

[0014] 2. Compared with the existing technology, this high-efficiency semi-open axial flow fan will not fall off instantly when the fan body is disassembled after bolts 2 and 3 are removed. Two limit rods are set to prevent the fan body from falling off during disassembly, thereby ensuring that the disassembly and maintenance work is carried out more smoothly and preventing the fan body from falling off and being damaged.

During this movement, the spring 17 is compressed until one side of the driving device completely passes through the fan body. At this time, the two limit rods 14 will pop out due to the force of the spring 17, and the position of the rotating rod 9 and the fan frame can be positioned by the two limit rods 14 so that no deviation occurs during installation. Then, they are fixed by bolt 2 10 and bolt 3 13.
