Description

Technical Field

[0001] The invention relates to the technical field of cooling and ventilation, and in particular to a special cylindrical water power ventilation structure for a cooling tower fan. Background Art

[0002] Cooling tower is a common industrial cooling equipment, which is mainly used to reduce the temperature of water through heat exchange. Through countercurrent gas heat exchange technology, hot water or hot air is brought into contact with air to achieve heat transfer and dissipation, thus ensuring the normal operation of the system.

[0003] The existing cooling tower fan uses a motor-driven fan for heat exchange. This motor-driven hydrodynamic ventilation cooling operation not only requires a large amount of electric energy to drive, but also the water pressure pumped by the water pump for the cooling water circulation in the cooling tower is not effectively utilized. At the same time, when facing the hot water flow in different production systems, the water delivery flow of the cooling tower is fixed, and the cooling tower ventilation structure is difficult to automatically adjust the power of the cooling tower fan according to the water flow, as well as the fan model used. As a result, it is difficult to automatically adjust the air volume when the water volume is small or large, resulting in low adaptability of the ventilation structure.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting a worm gear speed-increasing component, the rotating fan blades form a vortex to transport hot water to the infusion seat, and the column is driven to rotate by water power. In addition, the opening of the guide pipe on the water flow switch can be controlled according to the water flow of different production systems. When the water flow increases, the second guide pipe is opened. At this time, the impact of the water flow drives the rotating shaft to engage with the first gear and start rotating. At the same time, the gravity ball is affected by the centrifugal force generated during rotation and slowly moves to one side, so that the arc-shaped teeth at one end of the telescopic rod engage with the first gear on the rotating column, increasing the rotation speed of the column, thereby accelerating the rotation speed of the worm fan, and flexibly changing the flow rate of hot water to achieve the effect of increasing heat dissipation according to the increase in water flow. At the same time, the inertia of the gravity ball drives the rotation of the worm fan, and can also provide a certain inertia for the rotation of the worm fan to generate continuous rotational force.

[0019] By setting up a power drive component and utilizing the coordination of the main infusion pipe and the branch infusion pipe, the water power drives the worm gear to rotate, thereby driving the entire system to operate, reducing dependence on external electricity and reducing energy consumption. When facing a large amount of water flow, it is first run through the branch infusion pipe and then transported to the main infusion pipe. While increasing the water flow rate, it increases the conversion of mechanical energy, accurately controls the water flow, ensures the efficient circulation of water in the system, and improves energy utilization efficiency. At the same time, the design of the rotating water chamber and the atomizing nozzle allows the water to be more evenly distributed on the packing of the cooling tower during the driving process, increasing the contact area between water and air. The water source is sprayed out through multiple groups of inclined nozzles, which also generates a driving force to ensure the rotation of the fan blades, thereby improving the cooling effect, accelerating the cooling process, reducing the complex motors, transmission devices and other components in traditional cooling towers, reducing manufacturing costs, reducing maintenance points and failure rates, and improving the reliability and stability of the system.

[0020] By setting an angle adjustment component, the rotation angle of the fan blades can be changed to adjust the air volume and heat dissipation efficiency in the cooling tower. When the water flow increases, a stronger cooling effect is required, and the gravity ball drives the rotation of the second gear to increase the rotation speed of the column, thereby further accelerating the rotation speed of the volute fan and flexibly changing the flow rate of hot water. While improving the heat dissipation effect according to the water flow rate, the rotation angle of the fan blades can also be increased to increase the fan angle, thereby increasing the air volume and accelerating the evaporation and heat dissipation of water. When the cooling demand is low, the rotation angle can be reduced to reduce energy consumption and enhance system flexibility. The adjustability of the fan blade rotation angle enables the ventilation structure to adapt to different working environments and cooling needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 11As shown, the embodiment of the present invention provides a cylindrical water-powered ventilation structure dedicated to a cooling tower fan, comprising a tower body 1, a water basin 2 is installed at the bottom of the tower body 1, a water inlet pipe 3 is installed at one end of the water basin 2, a return pipe 4 is installed at the top of the water inlet pipe 3, a water pump 5 is provided at one end of the water inlet pipe 3, a water outlet pipe 9 is installed at one end of the water basin 2, a filler 10 is installed inside the tower body 1, a temperature sensor 11 is installed on the inner wall of the water basin 2, a column 12 is rotatably connected to the top of the tower body 1, a power chamber 13 is installed on the surface of the column 12, and a reduction gear 14 is installed inside the power chamber 13; a worm gear speed-increasing component 6, the worm gear speed-increasing component 6 is installed at the inlet At one end of the water pipe 3, the worm gear speed-increasing assembly 6 is used to provide power for the water flow flowing into the volute flow channel bin 63, and drive the fan blades 64 to rotate; the power drive assembly 7, the power drive assembly 7 is installed on the top of the worm gear speed-increasing assembly 6, the power drive assembly 7 is used to transport hot water to the atomizing nozzle 79 for spraying, and drive the rotating water chamber 78 to rotate; the angle adjustment assembly 8, the angle adjustment assembly 8 is installed on the top of the power drive assembly 7, the angle adjustment assembly 8 is used to adjust the rotation angle of the fan blade 86 at the top of the tower body 1; the worm gear speed-increasing assembly 6 is installed at the bottom of the power drive assembly 7, and the power drive assembly 7 is installed at the bottom of the angle adjustment assembly 8.

[0042] As an implementation method in this embodiment, Figures 4 to 7As shown, the worm gear speed increasing assembly 6 includes a water flow switch 61, which is installed at one end of the water inlet pipe 3. A guide tube 62 is installed on the top of the water flow switch 61, and a volute flow channel bin 63 is installed at one end of the guide tube 62. A first gear 66 is installed on the surface of the column 12, and a rotating shaft 65 is also installed on the surface of the column 12. A fan blade 64 is installed at one end of the rotating shaft 65. An annular top block 67 is installed on the top of the volute flow channel bin 63, and the annular top block 67 is arranged on the moving track of the rotating shaft 65. A support plate 68 is installed at one end of the rotating shaft 65, and a threaded column 69 is installed on the top of the support plate 68. A second gear 610 is installed at the bottom of the threaded column 69, and one end of the second gear 610 is meshedly connected with a toothed plate 611. The toothed plate 611 is meshed with the second gear 610. A moving block 612 is installed at one end of the plate 611, and the moving block 612 is sleeved on the surface of the telescopic rod 613. One end of the telescopic rod 613 is installed at one end of the rotating shaft 65. A gravity ball 614 is installed at one end of the telescopic rod 613. An arc tooth 617 is installed at the other end of the telescopic rod 613. The arc tooth 617 is arranged below the first gear 66. A spring 616 is installed at one end of the moving block 612. A support rod 615 is installed at one end of the moving block 612. When the water flow switch 61 controls the start and stop quantity of the switch by judging the flow rate of the water flow, when the water flows through the water flow switch 61, the water flows through the narrow diameter of the guide pipe 62 and is sprayed onto the fan blade 64 in the volute flow channel bin 63. At this time, the fan blade 64 is impacted by the water flow and starts to move. The rotating shaft 65 is driven to rotate. When the rotating shaft 65 rotates, the column 12 rotates accordingly. At the same time, the water flows through the volute flow chamber 63 to the top of the other end. When the water flow in the production system is large, the second group of water flow switches 61 are opened again. After the water flow switch 61 is opened, the water flow continues to impact the fan blades 64 in the second group of volute flow chambers 63, causing the fan blades 64 to start rotating. When the second group of fan blades 64 rotates, the rotating shaft 65 is driven to move slowly upward. When the rotating shaft 65 moves upward and touches the annular top block 67 installed on the top of the volute flow chamber 63, it stops moving, so that the arc tooth 617 at one end of the telescopic rod 613 is engaged with the first gear 66 on the rotating column 12, and then rotates with the first gear 66. When the arc tooth 617 at one end of the telescopic rod 613 is engaged with the first gear 66 on the rotating column 12, the arc tooth 617 is engaged with the first gear 66 on the rotating column 12, and then rotates with the first gear 66. When the toothed plate 617 rotates, the gravity ball 614 at the other end of the telescopic rod 613 moves toward one end under the influence of centrifugal force. When the gravity ball 614 moves, it drives the moving block 612 to move. When the moving block 612 moves to one end, it drives the support rod 615 and the other moving block 612 to move, thereby preventing the telescopic rod 613 from being deformed. At the same time, when the moving block 612 moves, the spring 616 installed at one end of the moving block 612 is stretched, and the toothed plate 611 installed at one end of the moving block 612 moves. When the toothed plate 611 moves, the second gear 610 meshingly connected at one end of the toothed plate 611 rotates. When the second gear 610 rotates, the threaded column 69 installed on the support plate 68 starts to rotate.

[0043] As an implementation method in this embodiment, Figures 5 to 9 As shown, the power drive assembly 7 includes an infusion seat 71, a main infusion pipe 72 is installed on the top of the infusion seat 71, and an infusion branch pipe 73 is also installed on the top of the infusion seat 71. A one-way valve 74 is installed at one end of the infusion branch pipe 73, and the output end of the one-way valve 74 is connected to the main infusion pipe 72. A liquid separation chamber 75 is installed at one end of the main infusion pipe 72, and a rotating block 76 is rotatably connected to the inner wall of the liquid separation chamber 75. The rotating block 76 is installed on the surface of the column 12. A pressure pipe 77 is installed on the top, and a rotating water chamber 78 is installed on the top of the pressure pipe 77. An atomizing nozzle 79 is installed at one end of the rotating water chamber 78. When the water starts to flow into the infusion seat 71 and then is transported to the infusion main pipe 72, the infusion main pipe 72 then transports the water to the liquid separation chamber 75. At this time, the rotating block 76 rotates with the column 12, and the water in the liquid separation chamber 75 continues to be transported to the rotating water chamber 78 through the pressure pipe 77. When the water reaches the rotating water chamber 78, the water flows through the atomizing nozzle 79 tilted at one end of the rotating water chamber 78 to spray water to the inside of the tower body 1, covering the surface of the filler 10, and at the same time, the rotating water chamber 78 starts to rotate due to the spraying force of the atomizing nozzle 79. The rotation of the rotating water chamber 78 drives the round seat 811 installed on the top of the rotating water chamber 78 to rotate synchronously. When the water flow rate is large, the infusion seat 71 of other groups first delivers the water flow to the one-way valve 74 through the infusion branch pipe 73 and then to the infusion main pipe 72. The water flow rate of the infusion branch pipe 73 is transported, so that the water flow speed in the infusion main pipe 72 is increased again. At the same time, when the water flow speed and capacity in the infusion main pipe 72 are expanded, the atomizing nozzle 79 installed at one end of the rotating water chamber 78 increases the spraying force, and the rotation speed of the rotating water chamber 78 is also increased. Then the reduction gear 14 in the power cavity 13 starts to appropriately reduce the speed of the column 12 to ensure the stable operation of the device.

[0044] As an implementation method in this embodiment, Figures 6 to 11As shown, the angle adjustment assembly 8 includes a round seat 811, which is mounted on the surface of the column 12, a rotating groove seat 85 is mounted on one end of the round seat 811, and a fan blade 86 is mounted on one end of the rotating groove seat 85. A threaded sleeve 81 is threadedly connected to the surface of the threaded column 69, and a rotating seat 82 is mounted on one end of the threaded sleeve 81. One end of the rotating seat 82 is rotatably connected to a rotating rod 83. A connecting rod 84 is mounted on the bottom of the rotating rod 83. One end of the connecting rod 84 is mounted on one end of the rotating groove seat 85. The rotating groove The top of the seat 85 is rotatably connected to an annular push rail 87, and a fixed block 88 is installed at the bottom of the annular push rail 87. One end of the fixed block 88 is rotatably connected to a rotating tube 89, and one end of the rotating tube 89 is installed with a connecting rod 810. One end of the connecting rod 810 is installed at one end of the rotating groove seat 85. When the threaded column 69 rotates, it means that the water flow in the production system is large and the required cooling effect is greater. Then the threaded sleeve 81 threadedly connected to the surface of the threaded column 69 starts to move upward. When the threaded sleeve 81 moves upward, the thread The rotating seat 82 installed at one end of the sleeve 81 drives the rotating rod 83 connected to one end of the rotating seat 82 to move. When the rotating rod 83 moves, the connecting rod 84 installed at one end of the rotating rod 83 starts to move. When the connecting rod 84 moves, the rotating groove seat 85 installed at one end of the connecting rod 84 starts to be pulled by the connecting rod 84 to rotate at one end of the round seat 811. When the rotating groove seat 85 rotates, the fan blade 86 installed at one end of the rotating groove seat 85 rotates with the rotation of the rotating groove seat 85. At this time, when the rotating groove seat 85 rotates, the fan blade 86 installed at one end of the rotating groove seat 85 rotates. When the movable slot seat 85 rotates, the annular push rail 87 installed on the top of the rotating slot seat 85 moves. When the annular push rail 87 moves, the rotating tube 89 on the fixed block 88 installed at the bottom of the annular push rail 87 moves. When the rotating tube 89 moves, the connecting rod 810 installed at one end of the rotating tube 89 moves along with it. When the connecting rod 810 moves, it drives the rotating slot seats 85 of other groups to rotate together at one end of the round seat 811. When the fan blade 86 changes its angle, the ventilation volume in the tower body 1 increases and the cooling effect is enhanced.

[0045] The working principle of the technical solution provided by the present invention is as follows:

[0046] When using the device, first ensure that the water system between the tower body 1 and the water inlet pipe 3, the water outlet pipe 9 and the water return pipe 4 is correctly connected, and the water pump 5 operates normally to ensure that it is in good working condition.

[0047] Then turn on the water pump 5 to allow water to flow into the tower body 1. At this time, the worm gear speed increaser assembly 6 starts to run. The water flow switch 61 controls the start and stop number of the switch by judging the flow rate of the water flow. After the water flows through the water flow switch 61, the water flows through the narrow diameter of the guide tube 62 and is sprayed onto the fan blades 64 in the volute flow channel bin 63. At this time, the fan blades 64 are impacted by the water flow and start to drive the shaft 65 to rotate. When the shaft 65 rotates, the column 12 rotates accordingly. At the same time, the water flows through the volute flow channel bin 63 to the top of the other end. When the water flow in the production system is large, the second group of water flow switches 61 is opened again. After the water flow switch 61 is opened, the water continues to impact the fan blades 64 in the second group of volute flow channel bins 63, causing the fan blades 64 to start rotating. When the second group of fan blades 64 rotates, it drives the shaft 65 to move slowly upward. When the shaft 65 moves upward and touches the annular top block 67 installed on the top of the volute flow channel bin 63, it stops moving, so that the telescopic rod The arc-shaped tooth 617 at one end of 613 meshes with the first gear 66 on the rotating center column 12, and then rotates with the first gear 66. When the arc-shaped tooth 617 rotates, the gravity ball 614 at the other end of the telescopic rod 613 moves toward one end under the influence of centrifugal force. When the gravity ball 614 moves, it drives the moving block 612 to move. When the moving block 612 moves to one end, it drives the support rod 615 and another moving block 612 to move to prevent the telescopic rod 613 from deforming. At the same time, when the moving block 612 moves, the spring 616 installed at one end of the moving block 612 is stretched, and the toothed plate 611 installed at one end of the moving block 612 moves. When the toothed plate 611 moves, the second gear 610 meshed with one end of the toothed plate 611 rotates. When the second gear 610 rotates, the threaded column 69 installed on the support plate 68 starts to rotate. When the threaded column 69 starts to rotate, the angle adjustment component 8 starts to operate.

[0048] After the water flows through the worm gear speed increasing component 6, the power drive component 7 starts to run, the water flows into the infusion seat 71, and then is delivered to the infusion main pipe 72. At this time, the infusion main pipe 72 transports the water to the liquid separation chamber 75. At this time, the rotating block 76 rotates along with the column 12, and the water in the liquid separation chamber 75 continues to be delivered to the rotating water chamber 78 through the pressure pipe 77. When the water reaches the rotating water chamber 78, the water flows through the inclined atomizing nozzle 79 at one end of the rotating water chamber 78 to spray water to the inside of the tower body 1, covering the surface of the packing 10. At the same time, the spray force of the atomizing nozzle 79 causes the rotating water chamber 78 to start rotating, and the rotation of the rotating water chamber 78 drives The round seat 811 installed on the top of the rotating water chamber 78 rotates synchronously, and when the water flow is large, the infusion seat 71 of other groups first conveys the water flow to the one-way valve 74 through the infusion branch pipe 73 and then to the infusion main pipe 72. The water flow conveyed by the infusion branch pipe 73 increases the water flow speed in the infusion main pipe 72. At the same time, when the water flow speed and capacity in the infusion main pipe 72 are expanded, the atomizing nozzle 79 installed at one end of the rotating water chamber 78 increases the spraying intensity. At the same time, the rotation speed of the rotating water chamber 78 is also increased. Then the reduction gear 14 in the power chamber 13 starts to appropriately decelerate the column 12 to ensure the stable operation of the device.

[0049] When the threaded column 69 rotates, it means that the water flow in the production system is large at this time, and the required cooling effect is greater, then the threaded sleeve 81 threadedly connected to the surface of the threaded column 69 begins to move upward, and when the threaded sleeve 81 moves upward, the rotating seat 82 installed at one end of the threaded sleeve 81 drives the rotating rod 83 connected to one end of the rotating seat 82 to move, and when the rotating rod 83 moves, the connecting rod 84 installed at one end of the rotating rod 83 begins to move, and when the connecting rod 84 moves, the rotating groove seat 85 installed at one end of the connecting rod 84 begins to rotate at one end of the round seat 811 pulled by the connecting rod 84, and when the rotating groove seat 85 rotates, the fan blade 86 installed at one end of the rotating groove seat 85 rotates with the rotation of the rotating groove seat 85, and at this time, when the rotating groove seat 85 rotates, the annular The push rail 87 moves. When the annular push rail 87 moves, the rotating tube 89 on the fixed block 88 installed at the bottom of the annular push rail 87 moves. When the rotating tube 89 moves, the connecting rod 810 installed at one end of the rotating tube 89 moves with it. When the connecting rod 810 moves, it drives the rotating groove seats 85 of other groups to rotate together at one end of the round seat 811. When the fan blade 86 changes its angle, the ventilation volume in the tower body 1 increases, the cooling effect increases, and then the cooled cooling water flows into the water basin 2. When the cooling water is stored in the water basin 2, the temperature sensor 11 senses its water temperature. When the water temperature in the water basin 2 is too high, the return pipe 4 re-transports the water in the water basin 2 to the water inlet pipe 3, and then sends it into the tower body 1 again for cooling treatment. When the water in the water basin 2 reaches the discharge temperature, it is discharged through the outlet pipe 9.
