Description

Technical Field

[0001] This utility model relates to the field of circulating fan technology, specifically a circulating fan. Background Technology

[0002] Circulating fans are a common type of ventilation equipment used in livestock and poultry breeding rooms. In livestock and poultry farms, the livestock and poultry are all concentrated in breeding rooms, and the breeding density is much higher than that of outdoor free-range breeding. In order to ensure the air circulation in the breeding room, it is necessary to install circulating fans to achieve the purpose of indoor air circulation.

[0003] Existing circulating fans are usually placed directly on the ground for use, which makes it difficult to install them at different angles, such as upside down or side wall, in different usage environments. Therefore, they do not meet the current requirements, so we have proposed a new type of circulating fan. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating fan to solve the problems mentioned in the background art, such as the fact that circulating fans are usually placed directly on the ground for use, which makes it difficult to install them at different angles such as upside-down installation or side-wall installation in different usage environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating fan, including a fan housing, an annular bracket movably fitted onto the outer surface of the fan housing, a T-shaped track groove provided on the outer surface of the annular bracket, four electric push rods provided on the outer side of the T-shaped track groove, a guide rod fixedly installed on the side of each electric push rod near the annular bracket, each guide rod movably engaging into the interior of the T-shaped track groove, and a movable disc fixedly installed on the end of each guide rod near the T-shaped track groove, each movable disc movably engaging into the interior of the T-shaped track groove.

[0006] Preferably, the output end of each electric push rod is fixedly connected to a hinge, and an assembly plate is hinged to the outer side of each hinge. Each assembly plate has four assembly holes on its surface.

[0007] Preferably, a servo motor is provided on the inner side of the fan housing, and the output end of the servo motor is connected to a fan through a coupling. A fixing plate is provided on the front side of the fan housing, and a grid mesh is fixedly installed on the outer surface of the fixing plate.

[0008] Preferably, four L-shaped hook rods are fixedly installed on the outer surface of the fixing plate, and each L-shaped hook rod is fixedly connected to the grid mesh.

[0009] Preferably, the outer surface of the servo motor is provided with four L-shaped hooks, and the ends of the L-shaped hooks are all bolted to the surface of the fan housing.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the cooperation of the ring bracket and the T-shaped track groove, allows the position of the assembly plate to be adjusted by moving the guide rod inside the T-shaped track groove during use. This enables the device to be installed at different angles in different environments, facilitating the installation and use of the device. At the same time, the output end is pushed out by the electric push rod, thereby adjusting the position of the assembly plate and making it easier to install the device in different positions.

[0012] 2. This utility model, through the cooperation of the hinge and the assembly plate, allows the assembly plate to rotate on the surface of the hinge, thereby adjusting the angle between the assembly plate and the electric push rod, so that the device can be installed and used on walls and other locations with different angles.
