Description

Technical Field

[0001] This utility model relates to the field of centrifugal fan technology, and more specifically, to an adjustable centrifugal fan. Background Technology

[0002] A centrifugal fan is a mechanical device that uses centrifugal force to draw gas in from the center and discharge it radially. It converts mechanical energy into kinetic energy of the gas using a rotating impeller and is primarily used for gas transport. Its core components include the impeller, casing, inlet, and outlet. It is widely used in ventilation, smoke extraction, air conditioning, and industrial production.

[0003] Most existing centrifugal fans are fixed to a frame during installation. The frame is used to place the centrifugal fan on the installation interface, such as the ground. In this case, it is not convenient to flexibly adjust the installation angle of the centrifugal fan according to the direction of the external connecting pipes, resulting in poor installation convenience. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the problems existing in the prior art, this utility model provides an adjustable centrifugal fan to solve the technical problem mentioned in the background art of poor adjustment flexibility of existing centrifugal fans during installation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable centrifugal fan includes a base with a mounting cavity at its bottom. A first electric push rod is disposed within the mounting cavity, and a moving component is disposed at the bottom end of the first electric push rod. A lifting seat is disposed above the base, and a lifting electric cylinder is disposed between the lifting seat and the base. A rotating seat is rotatably mounted on the top end of the lifting seat via a shaft and bearing. A first motor is disposed at the bottom end of the lifting seat in conjunction with the rotating seat. An adjusting seat is longitudinally hinged to the rotating seat, and an adjusting electric cylinder is hinged between the adjusting seat and the rotating seat. A shock absorber is disposed on the adjusting seat, and a mounting seat is disposed on the shock absorber. A fan assembly is disposed on the mounting seat.

[0009] The present invention is further configured such that the fan assembly includes a fan body, and a drive motor is provided on the mounting base. The drive motor is connected to the fan body for transmission. The drive motor is used to drive the impeller inside the fan body to rotate. This is the prior art and will not be described in detail in the present invention.

[0010] The present invention is further configured such that a mounting bracket is provided on the mounting base, and the fan body is mounted on the mounting base through the mounting bracket, thereby achieving a stable connection of the fan body on the mounting base.

[0011] The present invention is further configured such that the fan body is provided with an air inlet pipe and an air outlet pipe, and both the air inlet pipe and the air outlet pipe are provided with connecting flanges, thereby realizing the connection between the air inlet pipe and the air outlet pipe and the external pipe.

[0012] The present invention is further configured such that a support frame is provided on the rotating seat, and a connecting frame is provided at the bottom of the adjusting seat. The connecting frame and the support frame are rotatably connected by a shaft, and the rotatable hinge between the adjusting seat and the rotating seat is realized by the hinged connection between the support frame and the connecting frame.

[0013] The present invention is further configured such that the moving component includes a moving plate, the moving plate is mounted on the output end of the first electric push rod, and the bottom end of the moving plate is provided with a moving wheel.

[0014] The present invention is further configured such that limit frames are provided on both sides of the movable plate, and limit sliders are provided on the limit frames. A limit groove is formed on the inner wall of the mounting cavity, and the limit slider slides within the limit groove. When the movable plate moves within the mounting cavity, it will drive the limit frames and limit sliders to move. The limit sliders will move along the limit grooves. The cooperation between the limit sliders and the limit grooves can improve the installation and movement stability of the movable plate within the mounting cavity, and improve the overall support stability during movement.

[0015] The present invention is further provided that the base has fixing ears on both sides of the bottom end, and fixing holes are provided on the fixing ears. When the base is connected to the ground, fixing parts such as ground nails can be passed through the fixing holes and locked to the ground, thereby improving the connection stability between the base and the ground, thereby improving the overall support stability of the base, and improving the installation and support stability of the fan assembly during use.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an adjustable centrifugal fan with the following features:

[0018] Beneficial effects:

[0019] 1. This utility model includes a base with a mounting cavity at its bottom end. A first electric push rod is disposed within the mounting cavity, and a moving component is disposed at the bottom end of the first electric push rod. The moving component includes a moving plate, which is mounted on the output end of the first electric push rod. A moving wheel is disposed at the bottom end of the moving plate. Thus, when it is necessary to adjust the movement of the fan assembly, the first electric push rod can be activated. The first electric push rod controls the moving plate to drive the moving wheel outward from the mounting cavity, thereby lifting the base off the ground and facilitating overall movement. When the fan assembly is moved to a suitable position, the first electric push rod can be retracted, allowing the moving wheel to be stored back into the mounting cavity, bringing the base into contact with the ground. This improves the overall support stability of the fan assembly during use and enhances the stability of the fan body during operation.

[0020] 2. This utility model provides a lifting seat above the base, and a lifting electric cylinder is provided between the lifting seat and the base. A rotating seat is rotatably mounted on the top of the lifting seat through the cooperation of a shaft and a bearing. In this way, by controlling the lifting of the lifting electric cylinder, the lifting of the rotating seat at the top can be controlled. The lifting of the rotating seat can control the lifting of the adjusting seat above, thereby controlling the lifting of the mounting seat. This allows for the lifting and adjustment of the fan assembly located on the mounting seat, thus enabling flexible adjustment of the installation height of the fan body during installation.

[0021] 3. In this utility model, a first motor is installed at the bottom of the lifting seat in conjunction with a rotating seat. An adjusting seat is longitudinally hinged on the rotating seat, and an adjusting electric cylinder is hinged between the adjusting seat and the rotating seat. Thus, controlling the operation of the first motor allows the rotating seat to rotate horizontally on the lifting seat. The horizontal rotation of the rotating seat controls the horizontal rotation of the adjusting seat located on the rotating seat. The horizontal rotation of the adjusting seat allows the horizontal rotation of the mounting seat located on the adjusting seat, thereby achieving the horizontal rotation of the fan assembly. Simultaneously, activating the adjusting electric cylinder controls the extension and retraction of the adjusting electric cylinder, allowing the adjusting seat to rotate longitudinally along the hinge axis between the support frame and the connecting frame. This achieves the longitudinal rotation of the mounting seat installed above the adjusting seat, and consequently, the longitudinal rotation of the fan assembly located above the mounting seat. Thus, according to the above steps, the horizontal and vertical installation angles of the fan body in the fan assembly can be flexibly adjusted during installation, improving the flexibility and convenience of the fan body during installation.

A shock absorber 10 is installed on the adjusting seat 8, and a mounting seat 11 is installed on the shock absorber 10. A fan assembly is installed on the mounting seat 11.

[0032] Please see Figures 1-5 As one embodiment of the fan assembly: the fan assembly includes a fan body 12, and a drive motor 13 is provided on the mounting base 11. The drive motor 13 is connected to the fan body 12 through transmission. The drive motor 13 is used to drive the impeller inside the fan body 12 to rotate. This is the prior art, and this utility model will not elaborate on it.

[0033] Furthermore, this utility model provides a mounting bracket 14 on the mounting base 11, and the fan body 12 is mounted on the mounting base 11 through the mounting bracket 14, thereby achieving a stable connection between the fan body 12 and the mounting base 11.

[0034] More specifically: This utility model has an air inlet pipe 15 and an air outlet pipe 16 on the fan body 12. Both the air inlet pipe 15 and the air outlet pipe 16 are provided with connecting flanges 17, and the air inlet pipe 15 and the air outlet pipe 16 are connected to the external pipes through the connecting flanges 17.

[0035] Please see Figures 1-5 As one embodiment of the rotating seat 6: a support frame 18 is provided on the rotating seat 6, and a connecting frame 19 is provided at the bottom of the adjusting seat 8. The connecting frame 19 and the support frame 18 are rotatably connected by the cooperation of the shaft.

[0036] Please see Figures 1-5 As one embodiment of the moving component: the moving component includes a moving plate 20, which is mounted on the output end of the first electric push rod 3, and a moving wheel 21 is provided at the bottom end of the moving plate 20.

[0037] Furthermore, this utility model provides limiting frames 22 on both sides of the movable plate 20, and limiting sliders 23 on the limiting frames 22.

[0039] In summary:

[0040] This utility model includes a base 1, with a mounting cavity 2 at the bottom end of the base 1. A first electric push rod 3 is disposed in the mounting cavity 2, and a moving component is disposed at the bottom end of the first electric push rod 3. The moving component includes a moving plate 20, which is mounted on the output end of the first electric push rod 3. A moving wheel 21 is disposed at the bottom end of the moving plate 20. Thus, when it is necessary to adjust the movement of the fan assembly, the first electric push rod 3 can be activated. The first electric push rod 3 controls the moving plate 20 to drive the moving wheel 21 to extend outward from the mounting cavity 2, thereby lifting the base 1 off the ground and facilitating the overall movement. When the fan assembly is moved to a suitable position, the first electric push rod 3 can be retracted, allowing the moving wheel 21 to be stored in the mounting cavity 2, so that the base 1 contacts the ground, improving the overall support stability of the fan assembly during use and improving the stability of the fan body 12 during use.

[0041] The present invention provides a lifting seat 4 above the base 1, and a lifting electric cylinder 5 between the lifting seat 4 and the base 1. A rotating seat 6 is rotatably mounted on the top of the lifting seat 4 through the cooperation of a shaft and a bearing. In this way, by controlling the lifting of the lifting electric cylinder 5, the lifting of the rotating seat 6 at the top can be controlled. The lifting of the rotating seat 6 can control the lifting of the adjusting seat 8 above, thereby controlling the lifting of the mounting seat 11. This enables the lifting and adjustment of the fan assembly located on the mounting seat 11, thereby allowing flexible adjustment of the installation height of the fan body 12 during installation.

[0042] This invention features a first motor 7 mounted on the bottom of the lifting base 4 in conjunction with a rotating base 6. An adjusting seat 8 is longitudinally hinged to the rotating base 6, and an adjusting electric cylinder 9 is hinged between the adjusting seat 8 and the rotating base 6. Controlling the operation of the first motor 7 allows the rotating base 6 to rotate horizontally on the lifting base 4. This horizontal rotation of the rotating base 6 controls the horizontal rotation of the adjusting seat 8, which in turn controls the horizontal rotation of the mounting base 11 on the adjusting seat 8, thereby achieving wind... The horizontal rotation adjustment of the fan assembly is performed simultaneously with the activation of the adjustment cylinder 9. By controlling the extension and retraction of the adjustment cylinder, the adjustment seat 8 can be longitudinally rotated along the hinge axis between the support frame 18 and the connecting frame 19. This allows for the longitudinal rotation adjustment of the mounting seat 11 installed above the adjustment seat 8, and consequently, the longitudinal rotation adjustment of the fan assembly located above the mounting seat 11. Thus, the horizontal and vertical installation angles of the fan body 12 in the fan assembly can be flexibly adjusted during installation, improving the flexibility and convenience of the fan body 12 during installation.
