Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower equipment, in particular to a counter-current variable speed cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to reduce the water temperature. Its working principle is based on the heat exchange between water and air flow, which generates steam. The steam evaporates and takes away the heat, achieving the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat and ensure the normal operation of the system.

[0003] Existing cooling towers mainly promote heat dissipation inside the cooling tower by generating airflow through the operation of fans. The cooling towers are installed in fixed positions and work continuously. As the seasons change, natural wind will interfere with the operation of the cooling tower to a certain extent. The fan's resistance to external natural wind during operation will increase the fan's energy consumption, affect the heat dissipation efficiency, and even increase the working noise, causing damage to the fan.

[0031] Reference below Figures 1 - 4 A counter-flow variable speed cooling tower according to an embodiment of the present invention is described.

[0032] like Figures 1 - 4 As shown, the countercurrent variable speed cooling tower includes a cabinet 100, a support foot is arranged on the top of the cabinet 100, a mounting base 110 is arranged on the top of the cabinet 100, and the ratio of the diameter of the mounting base 110 to the width of the cabinet 100 is 0.7 to 0.9, which is convenient for installing a large-diameter fan mechanism 200.

[0033] The fan mechanism 200 is detachably mounted on the mounting base 110, and includes a driving assembly 210 and a blade assembly 220, and the blade assembly 220 is screwed to the driving assembly 210. Specifically, the driving assembly 210 can be driven by a servo motor, and the servo motor can be connected to the blade assembly 220 in a transmission or direct connection manner.

[0034] Among them, the blade assembly 220 includes a rotating disk 221 and an adjustable blade 224. A locking seat 222 is provided on the periphery of the rotating disk 221. The blade rod of the adjustable blade 224 is connected to the locking seat 222. The locking seat 222 is used to adjust and fix the installation angle of the adjustable blade 224. The adjustable blade 224 adopts a metal hollow structure.

[0035] Specifically, after the angle of the adjustable blade 224 is adjusted, the position is locked by the locking seat 222. The adjustable blade 224 is made of a lightweight aluminum alloy plate that is bent in one piece, and has the characteristics of light weight and stable structure. The locking seat 222 can easily lock the adjustable blade 224.

[0036] The counter-flow variable speed cooling tower of this embodiment adopts an adjustable blade assembly 220. When it is in the typhoon season in spring and summer, the wind volume and wind pressure generated by the fan mechanism 200 can be adjusted by adjusting the installation angle of the adjustable blade 224, making full use of the natural wind in the environment to improve the efficiency of the device and achieve the effect of reducing energy consumption and noise. In addition, the adjustable blade 224 can adapt to the flow of natural wind, reduce the resistance of the blade rotation, prevent blade damage, and further optimize energy consumption.

[0037] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the number of locking seats 222 is equal to that of adjustable vanes 224, and the locking seats 222 are evenly distributed around the rotating disk 221 at equal intervals. Specifically, in this embodiment, the adjustable vanes 224 and the locking seats 222 are respectively distributed at intervals of 90°, ensuring the balance of the rotating disk 221.

[0038] In some embodiments of the present utility model, as Figure 3 and Figure 4 shown, the locking seat 222 has an L-shaped structure, the adjustable vane 224 abuts against the side wall of the locking seat 222, and the position of the adjustable vane 224 on the locking seat 222 is fixed by a U-shaped lock 223. The U-shaped lock 223 penetrates through the locking seat 222 and the rotating disk 221 and is locked by a nut.

[0039] Specifically, the locking seat 222 is fixed on the rotating disk 221 by welding. Both the rotating disk 221 and the locking seat 222 are made of metal materials, which can make the center of gravity concentrated at the rotating shaft. The U-shaped lock 223 is a rigid U-shaped metal rod, and threads are provided at both ends of the U-shaped lock 223. After the U-shaped lock 223 presses the vane rod of the adjustable vane 224, the two ends penetrate below the rotating disk 221, and are screwed with the threads by nuts to press the position of the adjustable vane 224.

[0040] Furthermore, as Figure 3 and Figure 4 shown, there are two groups of U-shaped locks 223 on the locking seat 222, which are respectively located at the front and rear ends of the locking seat 222 and are used to lock both sides of the vane rod of the adjustable vane 224.

[0041] Specifically, in order to make the connection of the vane rod of the adjustable vane 224 more stable, in this embodiment, at least two groups of U-shaped lock 223 structures are provided, which are respectively located at both ends of the vane rod. In other embodiments, three or four groups of U-shaped locks 223 can also be provided, and the number of U-shaped locks 223 is adjusted according to the specifications of the adjustable vane 224.

[0042] In some embodiments of the present utility model, as Figure 3 and Figure 4 shown, the lower part of the adjustable vane 224 is arc-shaped, the upper part is flat, the head is arc-shaped, and the tail is narrowed into a sheet shape. Specifically, the adjustable vane 224 is integrally bent from an aluminum alloy plate, and the surface is smooth, which can effectively reduce the flow resistance.

[0043] Furthermore, as Figure 3 and Figure 4 shown, the tail of the adjustable vane 224 is inclined upward towards the upper part of the adjustable vane 224. Specifically, setting the tail of the adjustable vane 224 upward can increase the downward pressure during the operation of the vane assembly 220 and utilize the natural wind to assist in generating the downward pressure.

[0044] Further, as shown in Figure 3 and Figure 4 , the head of the adjustable blade 224 is downward and the tail is upward. Specifically, during the adjustment process, the adjustable blade 224 as a whole maintains the posture with the head downward and the tail upward.

[0045] In some embodiments of the present utility model, as shown in Figures 2 - 4 , reinforcing ribs 225 are provided inside the adjustable blade 224, and the reinforcing ribs 225 are arranged on both sides of the blade rod of the adjustable blade 224. Specifically, the reinforcing ribs 225 are welded inside the adjustable blade 224, which can improve the structural strength of the adjustable blade 224 and prevent the middle part of the adjustable blade 224 from deforming.

[0046] In some embodiments of the present utility model, as shown in Figure 1 and Figure 2 , a mounting frame 120 is provided at the port of the mounting seat 110, the driving assembly 210 is arranged above the mounting frame 120, and the blade assembly 220 is arranged below the mounting frame 120.
