Description
Technical Field
[0001] The utility model relates to the technical field of fans, in particular to a glass fiber reinforced plastic fan pulley cover. Background Art
[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge the gas. It is a driven fluid machine. Commonly referred to as fans include ventilators, blowers and wind turbines. Many existing fans are made of fiberglass. They are used in precision electronics, semiconductor industry, chemical industry, medicine, food, electroplating, electricity, steel, metallurgy, power environmental protection, sewage treatment, waste gas treatment and other industries. These industries usually need to deal with corrosive gases or need to work in corrosive environments. Fiberglass has the characteristics of light weight, high strength, corrosion resistance and high temperature resistance, which is the ideal choice to meet these needs. Fans usually need to install pulleys to achieve effective power transmission, speed regulation, buffering and shock absorption, and adapt to different shaft spacing. In actual use, pulley covers are usually installed outside the pulleys and belts to protect the pulleys and belts and prevent external debris from entering.
[0003] At present, the existing pulley cover usually includes a pulley cover body and a mounting plate, and the pulley cover is installed on the fan through the mounting plate to protect the pulley and the belt; however, this existing technology still has many shortcomings, for example: when the pulley and the belt are working, heat is generated when the belt and the pulley are in contact and move relative to each other, and the pulley cover cannot remove the heat. Long-term use can easily cause wear of the belt and the pulley, thereby reducing the service life of the belt and the pulley. Utility Model Content
[0004] The purpose of the utility model is to provide a glass fiber reinforced plastic fan pulley cover to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fiberglass reinforced plastic fan pulley cover, comprising a wheel cover body, two mounting openings being opened on one side of the wheel cover body, and two mounting rings being fixedly connected to one side of the wheel cover body, the two mounting rings corresponding to the two mounting openings, a mounting frame being fixedly connected to the inner wall of the mounting ring, a rotating shaft being rotatably connected to the mounting frame, a plurality of rotating fan blades being fixedly connected to one end of the rotating shaft away from the wheel cover body, the rotating shaft being driven by a pulley, and an air inlet being opened on the top of the wheel cover body.
[0006] As a further improvement to the above solution, a connecting shaft is provided on one side of the rotating shaft, a connecting plug plate is fixedly connected to the side of the connecting shaft close to the rotating shaft, and a connecting slot adapted to the connecting plug plate is opened on the side of the rotating shaft close to the connecting shaft.
[0007] As a further improvement to the above solution, the cross-sections of the connecting slot and the connecting plug board are both rectangular, and chamfers are provided on four sides of a surface of the connecting plug board close to the connecting slot.
[0008] As a further improvement to the above solution, a fixing plate is fixedly connected to a side of the connecting shaft away from the rotating shaft, and a plurality of fixing holes are opened on one side of the fixing plate.
[0009] As a further improvement to the above solution, a protective mesh plate is fixedly connected to the circumferential inner wall of the mounting ring, and a dustproof mesh plate is fixedly connected to the surrounding inner walls of the air inlet.
[0010] As a further improvement to the above solution, a mounting plate is fixedly provided on one side of the wheel cover body, and a plurality of mounting holes are opened on one side of the mounting plate.
[0011] As a further improvement to the above solution, the mounting plate and the wheel cover body are integrally formed, and both the mounting plate and the wheel cover body are made of fiberglass reinforced plastic.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] The utility model is characterized in that a rotating shaft is connected by rotating on a mounting frame, and a plurality of rotating fan blades are fixedly connected to one end of the rotating shaft away from the wheel cover body. The rotating shaft is driven by a pulley. When the fan starts to run, it drives the two pulleys to rotate. When the pulley rotates, it drives the rotating shaft to rotate. The rotating shaft drives the rotating fan blades to rotate, thereby generating wind force. The air is input into the interior of the wheel cover body through the air inlet and then discharged through the rotating fan blades. The heat generated by the friction between the belt and the pulley can be quickly taken away in time, thereby facilitating the heat dissipation of the belt and the pulley, reducing the wear of the belt and the pulley, and effectively increasing the service life of the belt and the pulley. At the same time, the rotation of the rotating fan blades is driven by the pulley, and there is no need to install an additional power source, which reduces the heat dissipation cost and keeps synchronization with the pulley.
[0014] The utility model provides a connecting shaft on one side of the rotating shaft, and the connecting shaft is fixedly connected to the connecting plug plate on the side close to the rotating shaft. A connecting slot that is compatible with the connecting plug plate is opened on the side of the rotating shaft close to the connecting shaft. During installation, the connecting shaft is first installed on the pulley through the fixing plate and the fixing hole, and then the angle of the rotating shaft is adjusted so that the connecting slot corresponds to the connecting plug plate. The wheel cover body is installed on the fan. After the wheel cover body is installed, the connecting plug plate will be inserted into the connecting slot, which makes it convenient to connect the rotating shaft and the pulley. By arranging chamfers on all four sides of the connecting plug plate close to the connecting slot, when there is a slight angular deviation between the connecting plug plate and the connecting slot, the connecting plug plate can be guided into the inside of the connecting slot through the inclined surface, which facilitates installation.

[0024] like Figure 1 As shown, a mounting plate 3 is fixedly provided on one side of the wheel cover body 1, and a plurality of mounting holes 4 are opened on one side of the mounting plate 3. The mounting plate 3 and the mounting holes 4 facilitate the installation of the wheel cover body 1 on the wind turbine. The mounting plate 3 and the wheel cover body 1 are integrally formed, and the mounting plate 3 and the wheel cover body 1 are both made of fiberglass. The mounting plate 3 and the wheel cover body 1 made of fiberglass have the characteristics of light weight, high strength, corrosion resistance and high temperature resistance, and are more suitable for different working scenarios.
[0025] Example 1 When the fan starts to run, it will drive the two pulleys to rotate, and when the pulleys rotate, they will drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the rotating fan blades 9 to rotate, thereby generating wind power, and inputting air into the inside of the wheel cover body 1 through the air inlet 7, and then discharged through the rotating fan blades 9, which can quickly take away the heat generated by the friction between the belt and the pulley, thereby facilitating the heat dissipation of the belt and pulley, reducing the wear of the belt and pulley, and effectively increasing the service life of the belt and pulley.
