Description

Technical Field

[0001] The present invention relates to the technical field of industrial fans, in particular to an installation and connection component for installing a wind blade on an industrial fan. Background Art

[0002] Industrial fans mainly consist of parts such as a motor, a wind blade, a housing, and a bracket. The motor is responsible for providing power, the wind blade converts the rotation of the motor into wind force, and the housing and the bracket play a role in protection and support.

[0003] The structure of an outer-rotor permanent magnet motor determines that the stator is located inside the rotor. The heat generated from the losses in the stator can only be transferred to the frame and other places through the conduction effect and then dissipated. There is no convective heat dissipation effect directly acting on the surface of the stator as in a conventional inner-rotor motor. Since the rotor of the outer-rotor permanent magnet motor is a rotating part and is located outside the motor, it naturally has a convective heat dissipation effect. As a result, the outer-rotor permanent magnet motor forms a phenomenon where the stator with large losses and large heat generation is inside with poor heat dissipation conditions, while the rotor has small losses and small heat generation but better heat dissipation conditions. This is what is criticized: the poor heat dissipation conditions of the outer-rotor permanent magnet motor, which in turn affect the popularization and use of the outer-rotor permanent magnet motor.

[0029] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the attached Figure 1-11 , and it is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment

[0031] Such as Figures 1 to 11As shown in the figure, the present invention discloses an energy-saving industrial fan motor assembly, which includes a shaft rod 120, a rotor seat body 100 and a stator seat body. The rotor seat body and the stator seat body are both installed on the shaft rod. The stator seat body includes a stator seat ring body, a stator seat support arm 104a and a stator inner hole seat 121. The stator seat ring body 121 has an inner hollow structure. One end of the stator seat support arm 104a is distributed along the inner wall of the stator seat ring body, and the other end is integrated on the outer end side of the stator inner hole seat 121, which is divided into several lower hollow channels E. The above-mentioned rotor seat body is provided with a rotor seat ring body, a rotor seat support arm 105 and a rotor inner hole seat 122. The rotor seat ring body has an inner hollow structure. One end of the rotor seat support arm is distributed along the inner wall of the stator seat ring body, and the other end is integrated on the outer end side of the rotor inner hole seat, which is divided into several upper hollow channels F. The upper hollow channels and the lower hollow channels correspond to each other one by one to form a convection heat dissipation channel. A lamp lighting component is installed below the stator seat body, and a lower air channel G is formed between the lamp lighting component and the stator seat ring body. The shaft rod adopts a hollow structure, and at least one stator seat support arm serves as a wire walkway 123. The hollow shaft rod is provided with a lower wire inlet port 126 and an upper wire outlet port 125 to form a wire integrated walkway.

[0032] An inner concave collecting groove 124 is formed in the stator seat ring body, and a water outlet 125 is formed in the inner concave collecting groove. The water outlet communicates with the lower hollow channel.

[0033] The upper and lower hollow channels formed by the segmentation of the rotor and the stator seat support arm correspond to each other one by one to form a directional convection heat dissipation path, accelerating the discharge of heat inside the motor and reducing the influence of temperature rise on efficiency. The lower air channel between the stator seat ring body and the lamp assembly, combined with the hollow structure of the shaft rod, forms a vertical air flow cycle, improving the overall heat dissipation efficiency and avoiding the increase in energy consumption caused by heat accumulation. The working temperature of the motor is reduced by 15%-30% through multiple heat dissipation channels, reducing energy loss caused by overheating and extending the service life of the motor.

[0034] Using a hollow shaft rod as a cable integrated walkway not only reduces material use and realizes lightweight, but also avoids the interference of external wire grooves on the air flow through structural integration, while improving the structural strength. The radial distribution design of the stator / rotor seat support arm divides out regular heat dissipation channels on the premise of ensuring the support strength, achieving a balance between mechanical performance and heat dissipation requirements. The optimized hollow structure can reduce the air resistance of the fan operation, increasing the air volume by about 12% under the same power, achieving the purpose of energy saving. This solution realizes the coordinated optimization of heat dissipation performance, space utilization and function expansion through structural innovation, and is especially suitable for industrial scenarios that require long-term high-load operation, achieving the energy-saving goal while ensuring stability.

[0035] Specify the support arm as a dedicated wire routing channel, which, in cooperation with the shaft rod inlet / outlet, forms a concealed wiring system, reducing the risk of wire wear and electromagnetic interference. The bottom of the stator base is integrated with a lamp assembly, using the motor body structure as the carrier of the lighting system to achieve the integrated spatial utilization of equipment and lighting in industrial scenarios.

[0036] The rotor seat body 100 is machined with at least two rotor seat support arms 105. In this solution, 5 are designed, and the five are distributed on the rotor seat body 100. The rotor seat support arms 105 are distributed on the rotor seat body 100. Each rotor mounting support 105 is provided with a reserved mounting hole 1053. A connecting bolt 102 is inserted into each reserved mounting hole 1053. The connecting bolt includes a head 1021 and a screw rod. It should be noted that in this solution, a non-threaded section is adopted within the reserved mounting hole 1053, aiming to quickly place the connecting bolt on the reserved mounting hole 1053 during assembly. The section extending outside the reserved mounting hole 1053 is a threaded section, which is used for connecting with the fan blade to insert the connecting bolt and achieve the connection with the fan blade. This design makes the connection more firm and can effectively prevent the fan blade from loosening or falling off due to vibration during operation.

[0037] An internal sunk groove 1051 is provided on the rotor seat support arm. The head 1021 of the above-mentioned connecting bolt is placed in the head sunk groove 1052 opened in the internal sunk groove 1051. A connecting plate 104 is installed in the internal sunk groove 1051. A fixed connection hole 1001 communicating with the internal sunk groove is opened on the end face of the rotor seat body. A fastener is installed on the fixed connection hole 1001. The fastener can be a screw, a screw rod, etc. The fastener extends into the internal sunk groove and is fixedly connected with the connecting plate. Specifically, it is a threaded connection method D. Threaded mounting holes are opened on the connecting plate, and the fastener is threadedly connected with it.

[0038] Each rotor seat support arm is provided with two reserved mounting holes 1053, and the fixed connection holes are arranged between the reserved mounting holes, and the distances between the fixed connection holes and the adjacent reserved mounting holes are all the same. This design makes the connection more uniform, can effectively disperse the vibration and force generated during the operation of the fan blade, and enhances the stability of the entire fan device.

[0039] Preferably, the reserved mounting hole on the inner sink groove for placing the head of the connecting bolt is processed into a polygonal hole structure, and as the head sink groove 1052, the polygonal hole structure of this scheme adopts a hexagon. The reserved mounting hole on the inner sink groove for placing the head of the connecting bolt is processed into a polygonal hole structure. This design can prevent the bolt from loosening due to vibration during operation, further improving the reliability and safety of the connection. The structure of this scheme is described in detail as follows: Through the design of the inner sink groove on the rotor seat support arm, the head of the connecting bolt can be completely placed in the head sink groove, avoiding the protrusion of the bolt head, making the entire connection assembly more compact. At the same time, a connecting plate is installed in the inner sink groove, and is fixedly connected to the rotor seat body by fasteners, ensuring the firmness and stability of the connection. A threaded mounting hole is opened on the connecting plate, and the fastener is threadedly connected to it. This design makes the installation and disassembly process simpler and faster, without the need for complicated tools or operations, reducing the difficulty and cost of installation.

[0040] During assembly, you only need to place the connecting bolt in the inner groove, place the head of the connecting bolt corresponding to the head groove 1052, then cover the connecting plate on the inner groove 1051, and then insert the fastener into the fixed connection hole 1001 on the other side to connect the two. After connection, you can lock the connecting bolt on the above-mentioned rotor seat body 100 to achieve installation, which greatly increases the convenience of installation and overall stability.

[0041] refer to Figures 8-11 A lighting assembly is installed under the base, and the lighting assembly includes a lighting body 100a. A mounting assembly is installed on the lower end surface of the lighting body facing the base, and the mounting assembly includes a plurality of fasteners 102a and a fastener 103a. The above-mentioned base is processed with an outer ring base and a plurality of stator seat support arms 104a connected to the inner center. The above-mentioned lighting body is connected to the outer ring base through the fastener 102a, and the fastener is snapped on the stator seat support arm. The fastener 103a includes a snap seat 1031a, a left snap piece 1033a and a right snap piece 1032a installed on the lighting body. Preferably, the snap seat is threadedly connected to the lighting body. Specifically, the buckle seat 1031a is installed on the lighting body 100a by screws 106a, and the left buckle piece 1033a and the right buckle piece 1032a are distributed on both sides of the buckle seat 1031a. The left buckle piece and the right buckle piece are close to each other to form a structure that is narrow at the top and wide at the bottom. At the same time, the ends of the left buckle piece and the right buckle piece are processed into a claw structure 1033a. In order to facilitate installation, the end surface of the claw structure 1033a is made into an arc structure 107a. One of the fasteners 103a can be installed with a fixed box 108a to further improve the firmness.

[0042] The above lighting main body is connected to the outer ring base by a fastener as follows: the outer ring base is provided with a threaded hole 1011a, the fastener includes a screw head 1021a, a screw rod and a heat-insulating nut seat 105a, the screw rod passes through the lighting main body and is installed on the heat-insulating nut seat 105a, and an external thread section 1022a is exposed, and the external thread section is matched and connected with the threaded hole of the outer ring base. The purpose of this structure is to make an integrated structure, first extend the screw rod of the fastener to the threaded hole 1011a of the outer ring base and then put on the heat-insulating nut seat, after being clamped by the fastener, directly rotate the fastener to achieve the connection between the outer ring base and the lighting main body.

[0043] This solution connects the lighting body to the outer ring base through fasteners, and uses fasteners to buckle on the stator support arm, achieving fast and stable assembly. The difficulty of operation is reduced, thereby significantly improving the assembly efficiency. The fastener adopts a left buckle piece and a right buckle piece that are brought inward to form a structure that is narrow at the top and wide at the bottom, and is processed into a claw structure at the end. This design enables the fastener to be firmly buckled on the stator support arm, enhancing the connection stability between the lighting component and the base. Since the lighting component is connected to the base through fasteners and fasteners, when disassembly or maintenance is required, it is only necessary to simply loosen the fasteners and fasteners, without the need for complicated operating tools, reducing maintenance costs and time costs. There is a space between the lighting component and the base. This design not only provides sufficient installation space for the lighting component, but also makes the overall structure of the fan motor more compact, optimizes space utilization, and achieves the effect of heat dissipation.
