Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to an angle-adjustable fan. Background Technology

[0002] In enclosed or semi-enclosed environments such as livestock farms and poultry houses, air circulation directly affects the animal's growth environment and production efficiency. To improve air quality, electric ventilation equipment, such as axial flow fans or circulating fans, is usually installed to achieve directional airflow and air exchange. However, most existing fans are fixed installations with a single airflow direction, making it difficult to flexibly adjust the airflow direction according to the spatial structure of the site or changes in stocking density. This results in insufficient ventilation or turbulent airflow in some areas, affecting the overall ventilation effect.

[0003] While existing technologies offer solutions for adjusting wind direction by changing the installation angle or manually adjusting the support frame, these methods have limited adjustment range, are cumbersome to operate, and suffer from poor stability, making them unsuitable for long-term use. Furthermore, a fixed airflow angle can lead to excessively high local wind pressure or airflow impacting livestock, negatively impacting environmental comfort and energy consumption control. Therefore, there is an urgent need for a ventilation device that allows for angle adjustment, structural stability, and easy installation to achieve more efficient and gentler air circulation and ventilation. Summary of the Invention

[0004] The purpose of this invention is to provide an angle-adjustable fan that can achieve more efficient and gentler air circulation and ventilation by utilizing its angle-adjustable structure.

[0005] This utility model is achieved through the following technical solution: an angle-adjustable fan, including a fan mounting base and a fan body; The fan mounting base includes a main board that can be fixedly mounted on a beam and a connecting rod that is hinged to the main board and extends downward. The hinge between the main board and the connecting rod is used to ensure that the connecting rod is vertically downward. An adjusting component is fixed in the middle of the connecting rod, and several load-bearing ropes of adjustable length are connected to the adjusting component. The fan body includes a motor mounting base hinged to the bottom of the connecting rod, a motor mounted in the motor mounting base, a turntable mounted on the motor output shaft, and several fan blades mounted on the turntable in a circular array with respect to the motor output shaft. The airflow direction of the fan body can be adjusted by adjusting the hinge angle between the motor mounting base and the connecting rod.

[0006] Compared with previous technologies, the beneficial effects of this utility model are as follows: 1. The main board is hinged to the top of the connecting rod to ensure that the connecting rod is vertically downward, and the motor mounting base is hinged to the bottom of the connecting rod to adjust the wind direction of the fan body, so that this utility model can flexibly adjust the wind direction according to the site environment, airflow distribution or seasonal changes to achieve exhaust ventilation.

[0007] 2. By utilizing the adjustment components and load-bearing ropes, the weight of the fan can be distributed to multiple points on the wall through the combination of the load-bearing ropes and turnbuckles. This allows the fan to maintain stable operation at different angles, avoiding vibration and noise problems caused by reverse airflow or pressure differences, thereby improving the overall efficiency and service life of the ventilation system.

[0008] 3. The modular connection between the components allows for quick installation on support surfaces at different angles. Installation does not require precise alignment, and the maintenance and disassembly process is simple, reducing labor costs. Attached Figure Description

Detailed Implementation

[0011] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description: like Figures 1 to 6 As shown, an angle-adjustable fan includes a fan mount and a fan body.

[0012] The fan mounting base includes a main board 11 that can be fixedly installed on a beam and a connecting rod 12 that is hinged to the main board 11 and extends downward. The hinge between the main board 11 and the connecting rod 12 is used to ensure that the connecting rod 12 is vertically downward. An adjusting member 31 is fixed in the middle of the connecting rod 12, and several load-bearing ropes 32 of adjustable length are connected to the adjusting member 31. The fan body includes a motor mounting base 21 hinged to the bottom of the connecting rod 12, a motor mounted in the motor mounting base 21, a turntable 22 mounted on the motor output shaft, and several fan blades 23 mounted on the turntable 22 in a circular array with the motor output shaft. The airflow direction of the fan body can be adjusted by adjusting the hinge angle between the motor mounting base 21 and the connecting rod 12.

[0013] It should be noted that the adjusting member 31 can move in the extending direction of the connecting rod 12, and the connecting rod 12 has a number of holes spaced apart in the extending direction for fixing the position of the adjusting member 31. The connection between the adjusting member 31 and the holes can be a threaded connection or a pin connection. By cooperating with the load-bearing rope 32, the load-bearing rope 32 can be connected to the wall or hung on a hook provided on the wall, which can achieve the effect of load-bearing and preventing fall, and can also prevent the connecting rod 12 from shaking when the motor is working.

[0014] The bottom surface of the main board 11 is equipped with two first hinge plates 111 spaced apart from each other, and each first hinge plate 111 is provided with a first pin hole 111-1; the top of the connecting rod 12 is provided with a first hole end 121 that mates with the first pin hole 111-1.

[0015] The outer wall of the motor mounting base 21 is equipped with two second hinge plates 211 spaced apart from each other, and each second hinge plate 211 is provided with a second pin hole 211-1; The bottom of the connecting rod 12 is provided with a second hole end 122 that mates with the second pin hole 211-1; The second hinge plate 211 is also provided with a plurality of first pin holes 211-2 distributed in an arc shape with the second pin hole 211-1 as the center; the connecting rod 12 is provided with second pin holes 123 that cooperate with the first pin holes 211-2; when the motor mounting base 21 rotates at a certain angle, the motor mounting base 21 can be limited by the cooperation of the first pin holes 211-2 and the second pin holes 123.

[0016] The main board of this invention is hinged to the top of the connecting rod to ensure that the connecting rod is vertically downward. The motor mounting base is hinged to the bottom of the connecting rod to adjust the wind direction of the fan body. This allows the invention to flexibly adjust the wind direction according to the site environment, airflow distribution, or seasonal changes to achieve exhaust ventilation.

[0017] Furthermore, the adjusting member 31 is equipped with several connecting buckles; The load-bearing rope 32 is provided with a turnbuckle 321 at one end near the adjusting member 31; one end of the turnbuckle 321 is connected to the load-bearing rope 32, and the other end of the turnbuckle 321 is connected to the connecting buckle.

[0018] The end of the load-bearing rope 32 is provided with a knot 322 or a hook.

[0019] This invention allows the weight of the fan to be distributed to multiple points on the wall through the combination of load-bearing ropes and turnbuckles, so that the fan can maintain stable operation at different angles and avoid vibration and noise problems caused by airflow reversal or pressure difference, thereby improving the overall efficiency and service life of the ventilation system.

[0020] Furthermore, the fan blade 23 is an arc-shaped fan blade with a circular arc cross-section. Arc-shaped fan blades are a conventional technical means that can more efficiently convert airflow into air volume.

[0021] Furthermore, the fan blade is provided with a toothed edge 231. The toothed edge 231 is a conventional technical means used to cut the airflow and reduce noise.

[0022] Furthermore, the main board 11 has bent edges 112 on both sides along its extension direction to increase strength. The bent edges 112 are a conventional technical means used to strengthen the strength of the board material.

[0023] Furthermore, the motor is a permanent magnet variable frequency motor. Permanent magnet variable frequency motors maintain high efficiency during high-pixel operation, and variable frequency start-up reduces current surges, extending equipment lifespan. In summary, during use: When installing this fan, the hinge angle between the main board 11 and the connecting rod 12 can be flexibly adjusted to stabilize the angle between them, ensuring the connecting rod 12 remains vertically downward. The adjusting component 31 and the load-bearing rope 32 can also be moved to prevent the fan from falling. Finally, depending on the site environment, airflow distribution, or seasonal changes, the hinge angle between the motor mounting base 21 and the connecting rod 12 can be adjusted. The motor mounting base 21 can be limited by the cooperation of the first pin hole 211-2 and the second pin hole 123, thereby adjusting the fan's airflow direction to a suitable angle. Afterward, the motor can be started for exhaust ventilation. During motor operation, the structure of the load-bearing rope 32 also helps to stabilize the connecting rod 12, preventing it from swaying. If necessary, the relative position of the adjusting component 31 in the extension direction of the connecting rod 12 can be moved, and the position of the adjusting component 31 can be fixed through different holes to achieve a better load-bearing effect.
