Description

Technical Field

[0001] This utility model relates to the field of energy-saving fan technology, and in particular to a large industrial energy-saving fan fixing device. Background Technology

[0002] The demand for ventilation and cooling in large spaces such as factory workshops, logistics warehouses, commercial venues, and livestock farms is increasing. Therefore, large industrial energy-saving fans are installed in these places to ventilate and cool them. These large industrial energy-saving fans are mostly ceiling fans and are usually connected to the ceiling of these places by fixed devices.

[0003] Patent document CN119122853A discloses a large industrial energy-saving fan fixing device, including a positioning plate, a mounting plate, fan blades, and a fixing mechanism. A mounting rod is provided at the bottom of the mounting plate, and the fan blades are rotatably mounted on the bottom of the mounting rod. The fixing mechanism includes a fixing seat, connecting columns, a first spring, and a second spring. The positioning plate is positioned above the mounting plate, and the fixing seat is positioned at the bottom of the positioning plate. Connecting columns are provided at the four corners of the top of the mounting plate, and the connecting columns are inserted into the fixing seat. A connecting ring is provided at one end of the connecting column inside the fixing seat. The first spring is located at the bottom of the connecting ring and sleeved on the connecting column, abutting against the inside of the fixing seat. One end of the second spring is connected to the top of the connecting ring, and the other end is connected to the top of the fixing seat. A connecting mechanism is provided between the mounting plate and the positioning plate, and the connecting mechanism is located between adjacent fixing mechanisms. This invention effectively improves the stability of the fan blade installation, reduces vibration and noise during rotation, and maintains smooth operation.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: the mounting surface at the top of these locations is either flat or sloping due to construction specifications and requirements to avoid rainwater leakage and water accumulation; and in order to improve ventilation and cooling efficiency, the installation is often lowered to a certain height, but this causes the connection point between the fan blades and the drive source to be far away from the mounting surface. This increases the vibration of the components directly connected to the mounting surface caused by the rotation of the fan blades by the drive source, eventually causing these components to loosen from the mounting surface. Therefore, a large industrial energy-saving fan fixing device is designed to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] like Figure 1 As shown, this type of large industrial energy-saving fan includes a top plate 1 with several through holes. The top plate 1 is used to contact the mounting surface at the top of some places and is fixed to the mounting surface by means of, for example, expansion bolts. A connecting body 3 is connected to the bottom of the top plate 1 through a first connecting structure 4. The bottom of the connecting body 3 is connected to a housing kit 2. The housing kit 2 is used to connect to the drive source of the large industrial energy-saving fan, so that the fan is fixed at a height below the mounting surface, allowing the fan to ventilate and cool the space below.

[0041] Since the housing sleeve 2 and the top plate 1 are connected as one unit through the connector 3 and the first connecting structure 4, the fan fixed on the housing sleeve 2 is at a distance from the top plate 1, so as to slightly lower the installation height of the fan and improve the cooling efficiency of the interior space. However, this will increase the vibration generated by the drive source driving the fan blades and transmit it to the top plate 1 connected to the mounting surface, causing the top plate 1 to loosen quickly from the mounting surface. Therefore, multiple reinforcing rods 5 are connected between the housing sleeve 2 and the top plate 1. Four are shown in the figure, including but not limited to these. Through the connection of this number of reinforcing rods 5, the strength of the connection point between the top plate and the fan blades and the drive source is strengthened, and the amplitude of the vibration generated by the fan at high speed is reduced.

[0042] Since large industrial energy-saving fans are mostly ceiling fans, their blades are many times larger than the drive source. When the blades rotate around the drive source, they can generate wind force many times greater than that of a household ceiling fan. However, at the same time, the vibration also increases significantly. Existing technologies mostly use multi-directional suspension steel wire ropes to fix the connection point between the blades and the drive source to ensure the stability of the fan during rotation. The application uses a reinforcing rod 5 to play a similar role to the suspension steel wire rope. At the same time, the reinforcing rod 5 is integrated with the device, which is easier to operate and install than the suspension steel wire rope. It can also deform according to the height adjustment (see below for details). It can be roughly divided into two parts: the casing kit 2 is extended or shortened by deformation to support the casing kit 2 away from or closer to the top plate 1, and the height distance between the casing kit 2 and the top plate 1 is maintained by the reinforcing rod 5.

[0043] like Figure 2 and Figure 3 As shown and referenced Figure 1The connecting body 3 consists of a first sleeve rod 31 and a second sleeve rod 32 sleeved outside the first sleeve rod 31. An adjustment structure is connected between the first sleeve rod 31 and the second sleeve rod 32. The adjustment structure is used to adjust the length of the first sleeve rod 31 and the second sleeve rod 32 superimposed, and to adjust the length of the first sleeve rod 31 from the bottom of the second sleeve rod 32. This allows the lower housing kit 2 to move away from or closer to the top plate 1 along a third direction (i.e., the length direction of the connecting body 3), and to change the height of the fan inside the housing kit 2.

[0044] Based on this, the first connecting structure 4 is connected between the first sleeve rod 31 and the top plate 1, and the first connecting structure 4 is used for the top plate 1 to rotate along the first and second directions (taking the top plate 1 as an example, the first direction is the length direction of the top plate 1, and the second direction is the width direction of the top plate 1), so that the top plate 1 can be fixed on the mounting surface at different angles, that is, with the support of the rotatable angles in the first and second directions, the top plate 1 can be attached to the mounting surface, which is either flat or inclined, without affecting the space where the fan inside the housing kit 2 is perpendicular to the space of the site;

[0045] Furthermore, the first connecting structure 4 includes two movable connecting seats 41 respectively arranged alternately on the top plate 1 and the first sleeve rod 31 along the first and second directions, and a first ear seat 42 fixed on one of the movable connecting seats 41 and connected to the other movable connecting seat 41.

[0046] In some embodiments, both movable connecting seats 41 are provided with arc-shaped grooves that pass through in the same direction. The bottom end of the first sleeve rod 31 is connected to the arc-shaped groove of the movable connecting seat 41 above it by a pin, and the first ear seat 42 is also connected to the arc-shaped groove of the movable connecting seat 41 above it by a pin. In this way, the top plate 1 rotates in the first direction through the movable connecting seat 41 below it with the pin on the first ear seat 42 as the axis.

[0047] Based on this, the top plate 1 can also rotate in a second direction with the pivot of the pivot of the movable connecting seat 41 on the first sleeve rod 31 via the movable connecting seat 41 below and the first ear seat 42, thereby covering and fixing on the mounting surface at different angles; and with the cooperation of the arc groove and the pivot, the top plate 1 can also move slightly, so that the vibration transmitted from below can drive the pivot in the arc groove, thereby reducing the impact on the top plate 1.

[0048] like Figure 3 As shown and referenced Figure 1The housing kit 2 includes a main body 21 and a base 22 integrally connected to the bottom of the main body 21. The center of the base 22 is hollowed out so that the fan drive source can enter the main body 21. Through the connection hole opened on the main body 21, the shield on the drive source can be connected to the main body 21 by screws, so that the fan is confined to the entire housing kit 2. The base 22 provides a connection node with the reinforcing rod 5.

[0049] like Figure 4 As shown, the reinforcing member 5 consists of a first connecting rod 51, a second connecting rod 52, and a first fastener 53, wherein one end of the first connecting rod 51 is connected to one end of the second connecting rod 52 by the first fastener 53, specifically as follows. Figure 4 As shown in one of the enlarged parts, the first fastener 53 is a bolt assembly. The screws of the bolt assembly pass through one end of the first connecting rod 51 and one end of the second connecting rod 52, respectively. Then, the nut of the bolt assembly is tightened on the end through which the screws pass to limit the angle formed between the first connecting rod 51 and the second connecting rod 52. For example, when the angle increases, the top end of the first connecting rod 51 is further away from the bottom end of the second connecting rod 52, so that the overall length of the reinforcing rod 5 increases, and the reinforcing rod 5 can be connected between the top plate 1 and the housing kit 2 after the fan height is further lowered.

[0050] A second connecting structure 6 is connected between the other end (i.e. the top end) of the first connecting rod 51 and the top plate 1. The second connecting structure 6 has the same function as the first connecting structure 4, that is, both can rotate in the first and second directions, so that the connection of the rod 1 will not affect the angular rotation of the top plate 1.

[0051] In some embodiments, such as Figure 4 As shown in another enlarged view, the second connecting structure 6 includes two hinge seats 61 that are staggered on the top plate 1 and the first connecting rod 51 along the first and second directions, and a second ear seat 62 fixed on one of the hinge seats 61 and connected to the other hinge seat 61. One of the hinge seats 61 can rotate in the first direction based on the second ear seat 62, and the other hinge seat 61 can rotate in the second direction through the second ear seat 62, as described in detail in the description of the first connecting structure 4.

[0052] In some instances, the first connection structure 4 and the second connection structure 6 are both constructed in the same way as the first connection structure 4 or the second connection structure 6.

[0053] In some instances, such as Figure 5 As shown and referenced Figure 1The adjustment structure includes multiple sets of limiting holes 7 equidistantly arranged along the height direction and penetrating through the first sleeve rod 31 and the second sleeve rod 32 along the width direction, and a second fastener 8 located between one set of limiting holes 7 on the first sleeve rod 31 and the second sleeve rod 32. The second fastener 8 has the same structure as the first fastener 53. Specifically referring to the above description of the second fastener 8, the second fastener 8 is used to limit the height of the second sleeve rod 32 sleeved on the first sleeve rod 31, increase the distance from the top of the first sleeve rod 31 to the bottom of the second sleeve rod 32, so that the connecting piece 3 grows as a whole, or conversely, shortens the overall length of the connecting piece 3.

[0054] In other embodiments, the adjustment structure includes a screw 9 rotatably connected within the first sleeve 31, a knob 10 fixed to the top of the screw 9 and partially protruding from the first sleeve 31, and a sleeve 11 fixed within the second sleeve 32 and threadedly connected to the screw 9. The knob 10 is used to rotate the screw 9 within the first sleeve 31, allowing the sleeve 11 to move on the screw 9, for example, moving it up or down, to increase or decrease the length of the sleeve 11 covering the screw 9, for example, allowing the second sleeve 32 to slide down the first sleeve 31, allowing the connector 3 to grow as a whole, or conversely, to shorten the overall length of the connector 3.

[0055] In some embodiments, both the first sleeve 31 and the second sleeve 32 are square tubes, and the inner diameter of the second sleeve 32 is equal to the diameter of the first sleeve 31, so that the second sleeve 32 can slide outside the first sleeve 31, or the first sleeve 31 can slide inside the second sleeve 32.

[0056] In some embodiments, the first sleeve 31 and the second sleeve 32 are both cylindrical, and the first sleeve 31 and the second sleeve 32 are able to slide vertically without rotation by a limiting structure provided between them.

[0057] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
