Description

Technical Field

[0001] The present disclosure relates to a structural member, and more particularly, to a reinforcement structure and a rotor. Background Art

[0002] The heat recovery wheel is a heat recovery device for air conditioners. It uses the temperature difference between the two convective air flows, supply air and exhaust air, to exchange heat. The heat recovery wheel is driven by a motor to rotate continuously to complete heat recovery. During operation, the aluminum foil and spokes on the wheel are subject to centrifugal force. If the circumferential pressure plate is not strong enough, it will break.

[0003] The existing large-sized wheels are wrapped with an iron plate in the circumferential direction, but the small-sized wheels are just an aluminum ring in the circumferential direction. Holes are opened in the aluminum ring and welded to the spokes on the wheel by welding. Due to the poor strength of aluminum, the centrifugal force of the spokes will cause cracks at the welding position. Utility Model Content

[0004] In order to solve the above problems, it is necessary to provide a reinforcement structure and a runner with a tightening function so that the spokes will not be pushed out of the circumferential plate even if they are subjected to centrifugal force, thereby extending the life of the runner.

[0008] Among them, several of the reinforcement plates are tightened on the outer ring of the wheel through a connecting assembly to increase the strength of the wheel.

[0009] In some embodiments, the connecting assembly includes a hammer nut, a bolt, and a connecting portion arranged at both ends of the reinforcing plate. The two ends of several reinforcing plates are respectively connected by the hammer nut and the bolt, and by tightening the bolt, several reinforcing plates are tightened on the outer ring of the wheel.

[0010] In some embodiments, the connection portion is formed by bending the reinforcing plate, the connection portion is in a "C"-shaped structure, and a through hole for the bolt to pass through is opened on the connection portion.

[0011] According to another aspect of the present application, a rotating wheel is provided, comprising an inner ring, an outer ring, a wheel core, and any one of the above reinforcement structures, wherein the wheel core is arranged between the inner ring and the outer ring, spokes are welded on the inner ring, the outer sides of the spokes are welded on the outer ring, and the wheel core is penetrated by the spokes, thereby forming a rotating wheel as a whole;

[0012] The reinforcement structure is tightened on the outer ring, and the reinforcement plate covers the welding points between the spokes and the outer ring to increase the strength of the wheel and prevent the spokes from radial displacement when subjected to centrifugal force.

[0014] Figure 1 It is a schematic diagram of the structure of the rotating wheel disclosed in the present invention.

[0016] Figure 3 It is a schematic diagram of the use of the rotating wheel disclosed in the present invention. DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] As mentioned above, the existing large-sized runners are wrapped with iron plates in the circumferential direction, but the small-sized runners are just an aluminum ring in the circumferential direction. Holes are opened in the aluminum ring and welded to the spokes on the runner by welding. Due to the poor strength of aluminum, the spokes will crack at the welding position due to the centrifugal force. The present application discloses a reinforcing structure in the circumferential direction of the runner, which has a tightening function, so that even if the spokes are subjected to centrifugal force, they will not push out of the circumferential plate, thereby extending the life of the runner.

[0019] The following will introduce the application of the reinforcement structure provided by the present disclosure in increasing the strength of the heat recovery wheel.

[0020] Please refer to Figure 1-2 A reinforcement structure includes a reinforcement plate and a connecting assembly, wherein the reinforcement plate can fit the outer ring of the runner, and the connecting assembly is used to connect the reinforcement plates so that several of the reinforcement plates are tightened on the outer ring of the runner; several of the reinforcement plates are tightened on the outer ring of the runner through the connecting assembly to increase the strength of the runner.

[0021] Exemplarily, the connecting assembly includes a hammer nut, a bolt, and a connecting portion arranged at both ends of the reinforcing plate, and the two ends of several of the fixing plates are respectively connected by the hammer nut and the bolt, and by tightening the bolt, several reinforcing plates are tightened on the outer ring of the wheel.

[0022] Exemplarily, the connection portion is formed by bending the reinforcing plate, the connection portion is in a "C"-shaped structure, and a through hole for the bolt to pass through is opened on the connection portion.

[0023] The present invention discloses a reinforcing structure in the circumferential direction of a rotating wheel. By covering the spoke welding points of the rotating wheel with metal reinforcing plates, the spokes are restricted from moving outwards under the action of centrifugal force and damaging the aluminum outer ring of the wheel core. The "C"-shaped opening structures at both ends of the reinforcing plates can cooperate with hammer nuts and bolts to complete the tightening function of the entire circumference.

[0024] Example 1

[0025] Please refer to Figure 1-Figure 3 The reinforcement structure of the wheel in the circumferential direction described in this scheme includes an aluminum inner ring 1 of a heat recovery wheel, an aluminum outer ring 2 of a heat recovery wheel, spokes 3, a reinforcement plate 4, a hammer nut 5, bolts 6, a bolt support block 7, a wheel core 8, and mounting screws 9.

[0026] The heat recovery wheel comprises an aluminum inner ring 1, on which spokes 3 are welded, and the outer sides of the spokes 3 are welded to the aluminum outer ring 2 of the heat recovery wheel, and the wheel core 8 is penetrated by the spokes 3, so as to form the wheel as a whole;

[0027] In this embodiment, both ends of the reinforcing plate 4 are "C"-shaped joints, and hammer nuts 5 and bolt support blocks 7 are placed in the "C"-shaped structures at both ends respectively; the number of reinforcing plates 4 is consistent with the logarithm of the central spokes 3, and the ends are connected and tightened by bolts 6;

[0028] The reinforcing plate 4 can cover the welding points of the spokes 3 and the aluminum outer ring 2 of the heat recovery wheel, so that when the wheel is running, the spokes 3 are still restricted by the reinforcing plate 4 when subjected to centrifugal force, and no radial displacement occurs, and the aluminum outer ring 2 of the heat recovery wheel is not damaged, thereby achieving the function of extending its service life.

[0029] Usage and steps:

[0030] 1) The middle part of the reinforcing plate 4 covers the welding position of the spokes 3 and the aluminum outer ring 2 of the heat recovery wheel so that its width and circumference are both in the middle.

[0031] 2) Use the mounting screws 9 to pre-fix the two ends of the reinforcing plate 4, and insert the hammer nut 5, bolt 6 and hammer nut 5, bolt support block 7 into the "C"-shaped structures at both ends of the reinforcing plate 4, and arrange the bolts in order from head to tail in a circular order.

[0032] 3) Repeat the second step to install the remaining reinforcement plates 4 respectively, and control the spacing between the reinforcement plates (4) so ​​that they are evenly distributed around the circumference.

[0033] 4) Remove all the mounting screws 9, and gradually tighten the bolts 6 along the circumference until they are tightened to the appropriate torque to complete the wheel core reinforcement installation.

[0034] The technical solution disclosed in the present invention arranges a reinforcement structure in the circumferential direction of the wheel, adds a metal reinforcement cover plate at the welding points between the spokes and the aluminum outer plate, and tightens the entire circumference, so that even if the spokes are affected by the centrifugal force of the wheel operation, they will not be pushed out and damage the aluminum outer plate of the wheel core, thereby increasing the strength of the wheel and extending its service life.
