[0002] Centrifugal fans are machines that rely on input mechanical energy to increase gas pressure and discharge gas; they are a type of driven fluid machinery.

[0003] The existing fan bases require precise positioning of the fan and motor during installation. The fan and motor are hoisted onto the base, and then positioning holes are drilled. The installation process is too cumbersome. In addition, different models of fans require different motors, and the base models are also different. This results in overly detailed classification of bases, poor universality, and easy errors in production and processing.

[0004] The existing connection between the base and the fan support is a bolt connection. After the fan support is fixed, the direction of the fan inlet and outlet cannot be adjusted. If it needs to be changed, different types of fan supports are required. The base and support have poor versatility and are not easy to install. Utility Model Content

[0036] like Figure 1-7 As shown, a centrifugal fan base includes a mounting block 101, a mounting plate 102, and a first support block 103. A connecting shaft 110 is provided on the side wall of the mounting plate 102, and a first connecting groove corresponding to the connecting shaft 110 is provided on the mounting block 101. The connecting shaft 110 and the first connecting groove cooperate to allow the mounting plate 102 to be rotatably connected to the mounting block 101. The connecting shaft 110 is located in the middle of the mounting plate 102. Two sets of first support blocks 103 are provided, located at both ends of the mounting plate 102 respectively. The centrifugal fan is mounted on the mounting plate 102. The first support blocks 103 can move along the mounting block 101 to allow the mounting plate 102 to rotate in order to adjust the air delivery angle of the centrifugal fan.

[0037] Specifically, the first support block 103 is provided with an inclined surface, and two sets of first support blocks 103 are arranged at both ends of the mounting plate 102 in the form of inclined surfaces facing each other. The mounting plate 102 is provided with inclined grooves corresponding to the first support blocks 103. The cooperation of the inclined surface and the inclined groove enables the first support block 103 to directly push the mounting plate 102 to flip when it moves.

[0038] Furthermore, the first support block 103 is provided with a slider 107, and the mounting block 101 is provided with a first movable groove and a second movable groove for the slider 107 to move. The sliders 107 on the two sets of first support blocks 103 are connected by a first connecting rod 108.

[0039] Furthermore, the mounting block 101 is in two sets, and the two sets of mounting blocks 101 are connected by a connecting plate 111. The bottom of the connecting plate 111 is provided with a mounting box 112, and the mounting box 112 is provided with a motor 113 for moving the first support block 103 of the drive rod.

[0040] Specifically, the connecting plate 111 is provided with a movable cavity, the first connecting rod 108 is provided with a transmission plate 115, and the motor 113 is provided with a transmission wheel 114, which is in transmission cooperation with the transmission plate 115.

[0041] When the air delivery angle of the centrifugal fan needs to be adjusted, the motor 113 drives the transmission wheel 114 to rotate. The rotation of the transmission wheel 114 causes the transmission plate 115 to move, and the two sets of first support blocks 103 move to adjust the angle of the mounting plate 102. Taking the movement of the two first support blocks 103 to the right side of the base as an example, the inclined surface of the first support block 103 at the front end of the mounting plate 102 abuts against the inclined groove of the mounting plate 102, pushing the front end of the mounting plate 102 to flip upward. The first support block 103 at the rear end of the mounting plate 102 moves away from the mounting plate 102, so that after the mounting plate 102 rotates around the connecting shaft 110, its rear end continues to abut against the inclined surface of the rear first support block 103, thereby raising the position of the centrifugal fan outlet and forming an upward inclined airflow. Conversely, when the two first support blocks 103 move to the left side of the base, the position of the centrifugal fan outlet decreases, forming a downward inclined airflow.

[0042] Furthermore, the mounting plate 102 is provided with a mounting groove, and the connecting shaft 110 is provided with a third connecting rod 116, which is located in the mounting groove; the mounting plate 102 is also provided with a second connecting groove, which communicates with the mounting groove, and a fixing plate 105 is provided in the second connecting groove; the fixing plate 105 is provided with a protrusion 106, and the inner wall of the second connecting groove is provided with a sliding groove for the protrusion 106 to move; the fixing plate 105 is fixed to the mounting plate 102 by screws.

[0043] Mounting plate 102 can be disassembled as needed. When disassembling mounting plate 102, unscrew the screws from mounting plate 102, slide mounting plate 102 relative to fixing plate 105, and remove mounting plate 102 from fixing plate 105. The fixing plate 105 and the second connecting groove can be used to easily connect connecting shaft 110 to mounting plate 102, so that mounting plate 102 and mounting block 101 are connected. The fixing plate 105 and mounting plate 102 are connected by screws to prevent mounting plate 102 from moving relative to fixing plate 105 when the centrifugal fan is working, thus ensuring the connection effect between mounting plate 102 and mounting block 101.

[0044] Furthermore, the bottom of the mounting block 101 is provided with a connecting block 117, which is connected to the bottom of the mounting block 101 by screws. The bottom of the connecting block 117 is provided with a water bladder 118, the bottom of the water bladder 118 is provided with a second support block 119, and the bottom of the second support block 119 is provided with a support pad 104, which is made of rubber. The water bladder 118 supports the mounting block 101, so that the mounting block 101 is always in a horizontal position, leveling the initial position of the centrifugal fan. At the same time, the water bladder 118 and the support pad 104 cooperate with each other to reduce the vibration transmitted from the centrifugal fan to the ground and ensure the stability of the base.

[0045] The appropriate height of the connecting block 117 can be selected for installation according to the installation location, thereby adjusting the height of the base and the height of the centrifugal fan, so that the centrifugal fan can meet a variety of different working conditions.

[0046] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
