Description

Technical Field

[0001] This utility model relates to the field of cooling fan equipment technology, and in particular to a connection device for a cooling tower fan driven by circulating water kinetic energy. Background Technology

[0002] The cooling tower fan is the core component of the cooling tower. It is used to accelerate airflow and enhance the heat exchange between water and air inside the tower. It is installed on the top and sides of the cooling tower and is driven by a motor to rotate, expelling hot and humid air from inside the tower while drawing in cool air from the outside, thereby lowering the temperature of the circulating water and meeting the cooling needs of industrial production.

[0003] Cooling tower fans need to be equipped with devices to ensure stable and safe operation, prevent displacement or detachment due to vibration during operation, provide support for subsequent inspection and maintenance, facilitate disassembly and assembly, protect the fans from external damage, and extend their service life.

[0004] During the operation of a cooling tower, the fan size is fixed and it is difficult to adapt to different areas of the cooling tower. This results in insufficient heat dissipation in some areas of the cooling tower, affecting the overall heat dissipation efficiency and failing to meet the heat dissipation requirements of cooling towers of different sizes. In existing technologies, a modular design is used, with multiple modular units combined to fill the cooling tower area. This can effectively adapt to cooling towers of different sizes, ensuring that all areas of the cooling tower can receive sufficient heat dissipation, improving the overall heat dissipation effect and meeting diverse heat dissipation needs. However, in actual use, the modular units are fixed with an integrated bracket. When an individual unit is damaged, it cannot be disassembled for repair. The entire bracket must be removed, increasing the difficulty and time cost of repair. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a connection device for a cooling tower fan driven by circulating water kinetic energy. It aims to improve the problem in the prior art where the unit modules are fixed by an integrated bracket. When an independent unit is damaged, it is impossible to disassemble the unit for repair. The entire bracket is removed, which increases the difficulty and time cost of repair.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a connecting device for a circulating water kinetic energy driven cooling tower fan, comprising a base plate, a cylinder fixedly connected to the top of the base plate, a connecting mechanism provided at the bottom of the base plate, the connecting mechanism being used for splicing several identical devices, and a reinforcing mechanism provided on the outer side of the cylinder, the reinforcing mechanism being used for reinforcing the device.

[0007] The connecting mechanism includes a mounting plate, the top of which is located at the bottom of the base plate. Multiple buckles are fixedly connected to the top of the mounting plate, and multiple buckle seats are fixedly connected to the top of the base plate. Multiple columns are fixedly connected to the outer wall of the cylinder, and baffles are fixedly connected to the outer sides of each of the multiple columns.

[0008] As a further description of the above technical solution:

[0009] The reinforcement mechanism includes multiple reinforcing ribs, the inner sides of which are fixedly connected to the outer wall of the cylinder. Multiple reinforcing strips are fixedly connected to the top of the base plate. Multiple bolts are threadedly connected to the top of the base plate. Nuts are fixedly connected to the outer walls of the multiple bolts. Washers are threadedly connected to the bottom of the multiple bolts.

[0010] As a further description of the above technical solution:

[0011] The base plate has a rectangular structure, and the top of the base plate has a square hole structure.

[0015] The connecting mechanism also includes multiple mounting holes, the inner sides of which are respectively opened on the top rear side and top left side of the base plate and the top of the mounting plate, and the multiple mounting holes are arranged in a relative manner.

[0016] As a further description of the above technical solution:

[0017] The inner sides of all the reinforcing ribs are made of right angles, and the tops of all the reinforcing ribs are made of rounded material.

[0018] As a further description of the above technical solution:

[0019] The height of the multiple reinforcing strips varies from high to low from the center to the edge of the base plate, and the multiple reinforcing strips are symmetrically distributed along the four corners of the center of the base plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by aligning the bottom of the base plate of the device to be spliced ​​with the mounting plate of another device, the buckle and the clip are engaged to achieve horizontal fixation, thereby achieving a stable splicing between devices and preventing movement during operation. When an independent unit is damaged, the buckle and the clip can be disassembled to repair the unit separately, reducing the difficulty and time cost of repair.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a connecting device for a circulating water-powered cooling tower fan, comprising a base plate 1, the base plate 1 having a rectangular structure, a square hole structure at the top of the base plate 1, a cylinder 2 fixedly connected to the top of the base plate 1, a plurality of guide vanes 5 fixedly connected to the inner side of the cylinder 2, the plurality of guide vanes 5 being made of ABS material and arranged in a swirling manner, a connecting mechanism 3 being provided at the bottom of the base plate 1, the connecting mechanism 3 being used for splicing several identical devices, and a reinforcing mechanism 4 being provided on the outer side of the cylinder 2, the reinforcing mechanism 4 being used for reinforcing the device;

[0034] The connecting mechanism 3 includes a mounting plate 31 with chamfered edges and an L-shaped structure. The top of the mounting plate 31 is located at the bottom of the base plate 1. Multiple buckles 32 are fixedly connected to the top of the mounting plate 31, and multiple buckle seats 33 are fixedly connected to the top of the base plate 1. Multiple columns 34 are fixedly connected to the outer wall of the cylinder 2, and baffles 35 are fixedly connected to the outer sides of the multiple columns 34. The connecting mechanism 3 also includes multiple mounting holes 36. The inner sides of the multiple mounting holes 36 are respectively opened on the top rear side and top left side of the base plate 1 and the top of the mounting plate 31. The multiple mounting holes 36 are arranged in a relative manner.

[0035] Specifically, the base plate 1 provides the installation foundation, the guide vanes 5 on the inner side of the cylinder 2 guide the flow of circulating water, the connecting mechanism 3 realizes the splicing between devices, and the reinforcement mechanism 4 enhances the overall stability of the device, working together to ensure the normal operation of the device in the cooling tower.

[0036] When the connecting mechanism 3 is used to assemble the devices, the operator first aligns the bottom of the base plate 1 of the device to be assembled with the top of the mounting plate 31 of the other device. The mounting plate 31 adopts an L-shaped structure and the edges are chamfered to provide initial docking support for the two devices. Then, the two devices are pushed so that the buckle 33 on the top of the base plate 1 and the buckle 32 on the top of the mounting plate 31 engage with each other, so as to achieve initial fixation of the two devices in the horizontal direction and avoid relative displacement of the devices in the early stage of assembly.

[0037] Multiple columns 34 fixed to the outer wall of cylinder 2 approach each other synchronously as the device is assembled. The baffles 35 on the outer side of the columns 34 contact each other, limiting the splicing part from the outside of the device, further restricting the relative movement of the two devices, and improving the structural stability after splicing. The operator passes the external fasteners through the mounting holes 36 on the top rear side, top left side and top of the mounting plate 1 and the top of the mounting plate 31. The mounting holes 36 are arranged opposite to each other to tightly fix the two devices, completing the splicing operation between the devices, ensuring that the overall structure of the device is stable after splicing and can withstand the force generated by the circulating water kinetic energy and the fan operation.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The reinforcing mechanism 4 includes multiple reinforcing ribs 41. The inner sides of the multiple reinforcing ribs 41 are all right-angled, and the tops of the multiple reinforcing ribs 41 are all rounded. The inner sides of the multiple reinforcing ribs 41 are all fixedly connected to the outer wall of the cylinder 2. The top of the base plate 1 is fixedly connected to multiple reinforcing strips 42. The height of the multiple reinforcing strips 42 changes from high to low from the center to the edge of the base plate 1. The multiple reinforcing strips 42 are symmetrically distributed along the four corners of the center of the base plate 1. The top of the base plate 1 is threadedly connected to multiple bolts 43. Nuts 44 are fixedly connected to the outer walls of the multiple bolts 43. Washers 45 are threadedly connected to the bottom of the multiple bolts 43.

[0039] Specifically, when the reinforcement mechanism 4 strengthens the structure of the device itself, multiple reinforcing ribs 41 are fixed to the outer wall of the cylinder 2 on the inner side. The inner side of the reinforcing ribs 41 adopts a right-angle structure to enhance the deformation resistance of the outer wall of the cylinder 2 and prevent the cylinder 2 from deforming under the impact of circulating water and the vibration of the fan. The top of the reinforcing ribs 41 is rounded. Through the structural characteristics of the reinforcing ribs 41, the flow resistance of water and air on the surface of the reinforcing ribs 41 is reduced, and local turbulence is prevented from affecting the kinetic energy transfer efficiency of the circulating water. Multiple reinforcing strips 42 fixed to the top of the bottom plate 1 are symmetrically distributed along the four corners of the center of the bottom plate 1. The height of the reinforcing strips 42 changes from high to low from the center to the edge of the bottom plate 1, which enhances the overall structural strength of the bottom plate 1, disperses the pressure borne by the bottom plate 1, and prevents the bottom plate 1 from bending and breaking due to long-term stress. At the same time, the symmetrically distributed reinforcing strips 42 can make the bottom plate 1 bear the force evenly and improve the structural stability of the bottom plate 1.

[0040] After the device is installed individually and spliced ​​together via the connecting mechanism 3, the operator inserts multiple bolts 43 through the pre-set holes at the top of the base plate 1 and makes threaded connections. The nuts 44 fixed to the outer wall of the bolts 43 move toward the surface of the base plate 1 as the bolts 43 rotate until the nuts 44 contact the surface of the base plate 1, thereby enhancing the tightness of the connection between the bolts 43 and the base plate 1. The washers 45 connected to the threads at the bottom of the bolts 43 are in close contact with the mounting surface, increasing the contact area between the bolts 43 and the mounting surface, preventing the bolts 43 from sinking into the mounting surface due to excessive pressure, reducing frictional wear between the bolts 43 and the mounting surface, and firmly fixing the mounting plate 31 to the base plate 1 to prevent displacement of the device during operation.

[0041] Working principle: The connection mechanism 3 enables the splicing of devices. The operator aligns the bottom of the base plate 1 of the device to be spliced ​​with the top of the mounting plate 31 of the other device. The mounting plate 31 adopts an L-shaped structure and the edges are chamfered. The mounting plate 31 and the base plate 1 provide initial docking support. Then, the two devices are pushed so that the buckle 33 on the top of the base plate 1 and the buckle 32 on the top of the mounting plate 31 engage with each other. The buckle 32 and the buckle 33 achieve initial horizontal fixation to prevent relative displacement in the early stage of splicing. The column 34 on the outer wall of the cylinder 2 moves closer to the other device as the splicing progresses. The baffles 35 on the outer side of the column 34 come into contact with each other. The baffles 35 and the column 34 limit relative movement from the outside. Then, the external fasteners are passed through the mounting holes 36 on the top rear side, top left side and top of the base plate 1 and the top of the mounting plate 31. The mounting holes 36 are arranged opposite to each other. The two devices are tightly fixed by the mounting holes 36 and the external fasteners to complete the splicing.

[0042] The structure is strengthened by the reinforcement mechanism 4. Multiple reinforcing ribs 41 are fixed to the outer wall of the cylinder 2 on the inner side. The inner side of the reinforcing ribs 41 adopts a right-angle structure. The reinforcing ribs 41 and the cylinder 2 enhance the cylinder 2's resistance to deformation and avoid deformation caused by circulating water impact and fan vibration. The top of the reinforcing ribs 41 is rounded. The structural characteristics of the reinforcing ribs 41 reduce the flow resistance of water and air and prevent turbulence from affecting the transfer of kinetic energy. The reinforcing strips 42 on the top of the base plate 1 are symmetrically distributed along the four corners of the center of the base plate 1. The height of the reinforcing strips 42 changes from high to low from the center of the base plate 1 to the edge. The reinforcing strips 42 and the base plate 1 enhance the structural strength of the base plate 1, disperse pressure, and avoid bending and fracture under long-term stress. The symmetrical distribution makes the base plate 1 bear the force evenly and improves stability.

[0043] To secure the device, after the device is installed and assembled individually, the operator inserts multiple bolts 43 through the pre-drilled holes at the top of the base plate 1 and connects them with threads. The nuts 44 on the outer wall of the bolts 43 move toward the surface of the base plate 1 as the bolts 43 rotate until they contact the surface of the base plate 1. The nuts 44 and bolts 43 enhance the tightness of the connection. The washers 45 at the bottom of the bolts 43 are threaded and then pressed tightly against the mounting surface. The washers 45 and bolts 43 increase the contact area, preventing the bolts 43 from sinking into the mounting surface due to excessive pressure and reducing frictional wear. The mounting plate 31 is firmly fixed to the base plate 1 by the cooperation of the bolts 43, nuts 44 and washers 45, preventing displacement during operation.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
