Description
Technical Field
The invention belongs to the field of oversized ceiling fans, and particularly relates to an oversized ceiling fan blade.
Background
The oversized ceiling fan is a ceiling fan product with the diameter of more than 2.5 meters, and is widely applied to high and large space places in recent years due to the outstanding characteristics of large coverage, energy consumption saving, soft airflow and the like. The blades of the existing super-large ceiling fan are all made of aluminum alloy materials, and the manufacturing process is an extrusion process or a stamping process and is a double-layer hollow structure.
The most common super-large ceiling fan has the length of blades of about 3.5 meters, the linear speed of the outer edge of each blade at a normal rotating speed of 50 revolutions per minute is about 19 meters per second, the blades have huge speed gradient difference along the radial direction, surge flow exists at the tip part of the outer edge of each blade and causes the vibration of each blade, the vibration is transmitted to the blade root part, the vibration is intensified at the fixed position of a bolt at the root part, and the blade is possibly broken at the position due to long-term vibration.
In actual use, the accidents of blade breakage and falling occur for many times.
Disclosure of Invention
In order to solve the problems, the invention aims at providing an oversized ceiling fan blade with a nested structure and adopting a plastic extrusion molding process, the blade is light in weight, and the load of a driving motor is reduced; and when the blade has a blade falling accident, the hazard of the blade is greatly reduced.
The invention also aims to provide the oversized ceiling fan blade with the nested structure and adopting the plastic extrusion molding process, the blade is internally provided with the metal core material, and the overall structural strength of the blade can be ensured while the weight of the blade is reduced.
In order to achieve the above object, the present invention has the following technical means.
The oversized ceiling fan blade with the nested structure and adopting the plastic extrusion molding process is characterized by comprising a metal core material and a blade main body manufactured by adopting the plastic extrusion molding process, wherein a main body cavity penetrating through the head end and the tail end of the blade main body is formed in the blade main body, and the metal core material is fixedly arranged in the main body cavity.
In the blade, the blade main body manufactured by a plastic extrusion molding process can be directly manufactured into the optimal appearance of the wind-driven mechanical blade, so that the production is more convenient and the efficiency is higher; the specific gravity of the plastic is only about 1/3 made of aluminum alloy, so that the blade is light in weight, the load of a driving motor is reduced, and the blade is cheaper than the blade made of the existing aluminum alloy material; when the blade falls, the harmfulness of the blade is greatly reduced because the whole blade is light. And the embedded structure-metal core material is arranged in the blade, so that the overall structural strength of the blade can be ensured while the weight of the blade is reduced, and the fracture of a blade main body is avoided. The plastic blade main body is more durable and can prevent aging; and the cleaning is simpler, the cleaning can be carried out by wet cloth, and no water stain trace is left.
Further, the blade main part is including last blade portion and lower blade portion, go up blade portion head end and lower blade portion head end integrated into one piece, go up blade portion tail end and lower blade portion tail end integrated into one piece, the main part cavity is enclosed by last blade portion and lower blade portion and is formed. The upper blade part and the lower blade part are of a closed-loop structure which is integrally formed, so that the overall strength of the blade is high.
Furthermore, more than one reinforcing rib is arranged in the main cavity, the main cavity is divided into more than two small cavities by more than one reinforcing rib, and the metal core material is fixedly arranged in any one of the small cavities. The arrangement of the reinforcing ribs is used for enhancing the overall strength of the blade.
Furthermore, the upper end and the lower end of the reinforcing rib are integrally formed with the upper blade part and the lower blade part respectively. The strengthening rib, upper blade portion and the setting of lower blade portion integrated into one piece further strengthen blade bulk strength.
Furthermore, the number of the reinforcing ribs is two, and a small cavity between the two reinforcing ribs is an installation cavity for installing the metal core material; the metal core material is fixedly arranged in the mounting cavity.
Furthermore, the thickness of the side wall of the blade body corresponding to the installation cavity is larger than that of the rest side walls of the blade body. Above-mentioned setting for when the metal core was installed in the installation cavity, it is more stable to be connected between this blade and the metal core.
Furthermore, the thickness of the two reinforcing ribs is larger than that of the side wall of the blade body, which does not correspond to the mounting cavity. Due to the arrangement of the thickness of the two reinforcing ribs, when the metal core material is arranged in the installation cavity, the blade and the metal core material are connected more stably. In particular, that is to say, the thickness of several of the side walls corresponding to the mounting cavity (stiffeners and corresponding side walls of the blade body) is thicker with respect to the thickness of the rest of the blade body; the blade can be effectively connected with the metal core material more stably.
Furthermore, the upper blade part and the lower blade part are both arc-shaped structures.
Furthermore, a tail wing plate is arranged at the tail end of the blade main body, and the tail end of the metal core material is fixed with the tail wing plate. Specifically, the side surface of the tail wing plate is abutted against the tail end of the blade main body, and can also be not contacted with the tail end of the blade main body. The heights of the upper side and the lower side of the tail wing plate exceed the heights of the upper side and the lower side of the blade main body, and the tail wing plate completely shields the tail end of the cavity of the main body. The tail wing plate is the most important part of the fan vibration (because when the blade rotates, the speed of the tail wing plate at the tail end is the highest), and the tail wing plate can transmit the vibration to the metal core material, so that the blade main body is prevented from being influenced by the vibration, and the blade main body is more stable.
Further, the head end of the metal core material extends out of the cavity of the main body to be exposed outside the main body of the blade to form a connecting part for connecting with an external structure.
The metal core material is a high-rigidity metal core material, such as an aluminum alloy profile or a steel pipe. The plastic material adopted by the blade main body is PVC, PE, PP, TPE, TPR, HDPE and other materials.
The invention has the advantages that the blade main body manufactured by the plastic extrusion molding process can directly manufacture the optimal appearance of the wind-driven mechanical blade, and is more convenient to produce and higher in efficiency; the specific gravity of the plastic is only about 1/3 made of aluminum alloy, so that the blade is light in weight, the load of a driving motor is reduced, and the blade is cheaper than the blade made of the existing aluminum alloy material; when the blade falls, the harmfulness of the blade is greatly reduced because the whole blade is light. And the metal core material is arranged in the blade, so that the overall structural strength of the blade can be ensured while the weight of the blade is reduced. The plastic blade main body is more durable and can prevent aging; and the cleaning is simpler, the cleaning can be carried out by wet cloth, and no water stain trace is left.
