Description

Technical Field

[0001] This utility model relates to the field of wind turbine control technology, and in particular to a wind turbine control device. Background Technology

[0002] Ventilation fans are typically installed on walls or roofs to provide ventilation to a target area. However, in actual operation, due to limitations imposed by installation layout, airflow path, and spatial structure, some areas can easily become dead zones, making it difficult for the fans to effectively ventilate these areas. Therefore, a fan angle control device is needed to dynamically adjust the fan's outlet angle, thereby covering these dead zones and ensuring overall ventilation effectiveness.

[0003] In the prior art, ventilation control devices and ventilation control systems are disclosed, which enable the fan to have changes in pitch angle and azimuth angle through the rotation angle adjustment mechanism and the tilt angle adjustment mechanism, so that the fan can exhaust air to different areas of the space.

[0004] However, its azimuth adjustment mechanism mainly relies on the meshing transmission between the motor and the gears and gear rings. After the angle adjustment is completed, the structure cannot achieve position locking. As a result, the vibration of the fan during operation can easily cause the meshing position of the gears and gear rings to shift, resulting in the fan angle shifting, affecting the ventilation effect and causing unstable ventilation. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a fan control device. By adopting a magnetic locking structure design, an azimuth angle locking mechanism is formed, which realizes the stable locking and flexible unlocking of the azimuth angle adjustment component, avoids the angle deviation problem caused by fan vibration, and ensures the stability of ventilation effect.

[0007] To achieve the above objectives, this utility model proposes a control device for a fan, comprising a top plate, a friction ring, an azimuth adjustment assembly, a pitch adjustment assembly, a locking assembly, and a fan body, wherein... The main body of the fan is movably mounted on the azimuth adjustment component via the pitch angle adjustment component. The azimuth adjustment component is mounted on the top plate and can be adjusted by rotating around the axial direction of the top plate. The friction ring is mounted on the top plate and sleeved on the outside of the azimuth adjustment component. The locking component is mounted on the outside of the azimuth adjustment component and can be adjusted by moving along the axial direction of the azimuth adjustment component. The locking component abuts against the friction ring.

[0008] In addition, the fan control device proposed above according to this utility model may also have the following additional technical features: Specifically, the azimuth adjustment assembly includes a connecting ring, a first driving member, and a mounting base. The mounting base is rotatably disposed outside the connecting ring via a bearing, and the first driving member is disposed inside the connecting ring, with its output shaft connected to the mounting base.

[0009] Specifically, the pitch angle adjustment assembly includes a connecting rod, a second driving member, and two collars, wherein the two collars are symmetrically arranged on the fan body, and the connecting rod and the second driving member are hinged to the two collars.

[0010] Specifically, the locking assembly includes a locking ring, multiple limiting rods, an adsorption plate, a positioning retaining ring, and multiple electromagnets. The multiple limiting rods are arranged in a ring and disposed on the locking ring, the multiple electromagnets are arranged in a ring and disposed on the positioning retaining ring, the adsorption plate is disposed at the bottom end of the limiting rod and is attracted and connected to the electromagnet, the limiting rod is slidably disposed within the positioning retaining ring, and an elastic element is sleeved on the outside of the limiting rod, with both ends of the elastic element abutting against the adsorption plate and the positioning retaining ring, respectively.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention utilizes a locking component to control the engagement and disengagement of the locking ring and friction ring by energizing and de-energizing an electromagnet. When the electromagnet is de-energized, the locking ring separates from the friction ring, allowing the azimuth adjustment component to rotate freely around the top plate axis, thus enabling flexible adjustment of the fan's azimuth angle. When the electromagnet is energized, the locking ring and friction ring engage tightly, achieving a stable lock on the azimuth adjustment component through friction, effectively preventing angular deviation caused by fan vibration. Furthermore, the magnetic locking structure in this invention not only simplifies the complexity of traditional gear transmission mechanisms but also ensures the stability and reliability of the ventilation effect.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, describes a fan control device according to an embodiment of the present invention.

[0017] like Figures 1-4 As shown, a fan control device according to an embodiment of the present invention includes a top plate 1, a friction ring 2, an azimuth adjustment component 3, a pitch adjustment component 4, a locking component 5, and a fan body 6. The fan body 6 is movably mounted on the azimuth adjustment component 3 via the pitch adjustment component 4. The azimuth adjustment component 3 is mounted on the top plate 1 and can be adjusted by rotating around the axial direction of the top plate 1.

[0018] It should be noted that the top plate 1 is used to install the entire control device. For example, the entire device can be installed on the roof through the top plate 1 to ensure the stability of the main body of the fan 6 and each control component during operation.

[0019] The pitch angle adjustment component 4 and the azimuth angle adjustment component 3 enable flexible control of the pitch angle and azimuth angle of the main body of the fan 6, thereby effectively covering the dead zone area of ​​air circulation and improving the ventilation effect.

[0020] The friction ring 2 is disposed on the top plate 1 and sleeved on the outside of the azimuth adjustment component 3. The locking component 5 is disposed on the outside of the azimuth adjustment component 3 and moves and adjusts along the axial direction of the azimuth adjustment component 3. The locking component 5 abuts against the friction ring 2.

[0021] It should be noted that the friction ring 2 is fixedly installed on the top plate 1, and friction particles are evenly distributed on its lower surface, which can increase the friction between it and the locking component 5. This ensures that after the azimuth adjustment component 3 is rotated to the designated position, a stable lock is achieved through the tight contact between the locking component 5 and the friction ring 2, preventing the fan body 6 from shifting due to vibration during operation.

[0022] In one embodiment of this utility model, such as Figure 2 As shown, the azimuth adjustment assembly 3 includes a connecting ring 31, a first driving member 32, and a mounting base 33. The mounting base 33 is rotatably disposed outside the connecting ring 31 via a bearing, and the first driving member 32 is disposed inside the connecting ring 31, with its output shaft connected to the mounting base 33.

[0023] It should be noted that the connecting ring 31 is fixedly installed on the lower surface of the top plate 1, the first driving component 32 is a servo motor, which is installed inside the connecting ring 31, and the mounting base 33 is used to install the pitch angle adjustment component 4.

[0024] It is understandable that when the first drive component 32 is started, its output shaft drives the mounting base 33 to rotate around the axis of the connecting ring 31, thereby driving the pitch angle adjustment component 4 and the fan body 6 to achieve azimuth angle control, so as to flexibly adjust the air outlet direction of the fan body 6 according to actual needs.

[0025] In one embodiment of this utility model, such as Figure 2 As shown, the pitch angle adjustment assembly 4 includes a connecting rod 41, a second driving member 42, and two collars 43. The two collars 43 are symmetrically arranged on the fan body 6, and the connecting rod 41 and the second driving member 42 are hinged to the two collars 43.

[0026] It should be noted that both collars 43 are fixedly installed on the outer wall of the fan body 6. One end of the connecting rod 41 is hinged to one collar 43, and the other end is fixedly connected to the mounting base 33. The second driving component 42 is an electric telescopic rod, one end of which is hinged to the other collar 43, and the other end is hinged to the mounting base 33.

[0027] Understandably, when the second drive unit 42 is started, its telescopic rod drives the fan body 6 to adjust the pitch angle around the hinge point between the connecting rod 41 and the collar 43. This allows for flexible adjustment of the air outlet pitch angle of the fan body 6 according to actual needs, so as to better cover the air circulation dead zone area at different heights.

[0028] In one embodiment of this utility model, such as Figures 3-4 As shown, the locking assembly 5 includes a locking ring 51, multiple limiting rods 52, an adsorption plate 54, a positioning retaining ring 55, and multiple electromagnets 56. The multiple limiting rods 52 are arranged in a ring and are disposed on the locking ring 51. The multiple electromagnets 56 are arranged in a ring and are disposed on the positioning retaining ring 55. The adsorption plate 54 is disposed at the bottom end of the limiting rod 52 and is attracted and connected to the electromagnets 56. The limiting rod 52 is slidably disposed inside the positioning retaining ring 55. An elastic element 53 is sleeved on the outside of the limiting rod 52. The two ends of the elastic element 53 abut against the adsorption plate 54 and the positioning retaining ring 55, respectively.

[0029] It should be noted that the locking ring 51 is slidably connected to the outer wall of the mounting base 33, and the inner wall of the locking ring 51 is provided with a groove. The outer wall of the mounting base 33 is provided with a guide protrusion and is slidably connected in the groove. Through the cooperation of the guide protrusion and the groove, it can be ensured that the locking ring 51 can move smoothly along the axial direction of the mounting base 33 without axial rotation.

[0030] The positioning retaining ring 55 is fixedly installed on the outer wall of the mounting base 33 and located below the locking ring 51. The limiting rod 52 slides in the preset through hole of the positioning retaining ring 55. The electromagnet 56 is installed on the lower surface of the positioning retaining ring 55. The adsorption plate 54 is located below the electromagnet 56 and is attracted to the adsorption plate 54. In the attracted state, the locking ring 51 is in close contact with the friction ring 2.

[0031] The elastic element 53 is a spring. When the electromagnet 56 is energized, the adsorption plate 54 moves upward and attracts the electromagnet 56, and the elastic element 53 is compressed. When the electromagnet 56 is de-energized, under the action of the elastic element 53, the adsorption plate 54 is pushed downward and separated from the electromagnet 56. The adsorption plate 54 drives the locking ring 51 to move downward through the limiting rod 52. The locking ring 51 separates from the friction ring 2 to release the position limitation of the azimuth angle adjustment component 3.

[0032] The connecting ring 31 is equipped with a PLC controller. The signal terminals of the PLC controller are connected to the signal terminals of the first drive unit 32, the second drive unit 42 and the electromagnet 56 respectively, so as to control the azimuth and pitch angles of the fan body 6.

[0033] In practical applications, when adjusting the pitch angle of the fan body 6, the second drive component 42 is activated. The second drive component 42 drives the fan body 6 to adjust the pitch angle around the hinge point between the connecting rod 41 and the collar 43, so that the outlet pitch angle of the fan body 6 can be adjusted according to actual needs.

[0034] When adjusting the azimuth angle of the main body 6 of the fan, the electromagnet 56 is de-energized and loses its magnetism. Under the action of the elastic element 53, the locking ring 51 separates from the friction ring 2, releasing the position restriction of the azimuth angle adjustment component 3. Then, the first drive component 32 is started. The first drive component 32 drives the mounting base 33 to rotate around the axis of the connecting ring 31. The mounting base 33 drives the pitch angle adjustment component 4 and the main body 6 of the fan to rotate synchronously, thereby realizing the adjustment of the azimuth angle.

[0035] Once the main body 6 of the fan is adjusted to the designated position, the control electromagnet 56 is energized. The electromagnet 56 generates magnetism and attracts the adsorption plate 54. The adsorption plate 54 drives the locking ring 51 to move upward through the limit rod 52, so that the locking ring 51 is in close contact with the friction ring 2. Under the action of friction, the position of the azimuth angle adjustment component 3 is locked to prevent the fan body 6 from shifting due to vibration during operation.

[0036] In summary, the fan control device of this utility model embodiment, by setting a locking component, uses the energization and de-energization of an electromagnet to control the contact and separation of the locking ring and the friction ring, thereby achieving stable locking and flexible unlocking of the azimuth angle adjustment component, preventing the fan body from shifting angle due to vibration during operation, and ensuring the stability and reliability of the ventilation effect.
