[0002] A cooling tower is a heat exchange device mainly used to cool water or other working fluids to near ambient temperature in a circulating system. It is widely used in industrial production; the basic principle of a cooling tower is to reduce the temperature of water through heat exchange between water and air.

[0003] When in use, hot water is sprayed downward to contact the coil pipe, and cooling water flows in the coil pipe. However, when the hot water is sprayed downward, the contact time with the coil pipe is short, resulting in low cooling efficiency of the hot water. Therefore, it needs to be cooled multiple times to reach the required temperature, causing energy waste. In order to accelerate the air flow in the cooling tower, a fan driven by a motor is generally provided on the cooling tower, and a large amount of electricity is required to drive the fan to operate. Summary of the Invention

[0005] In order to solve the above problems, the technical solution of the utility model is as follows:

[0006] An energy-saving cooling tower includes a tower body, a coil pipe is arranged inside the tower body, air inlet holes are arranged on the peripheral wall of the tower body below the coil pipe, and further includes a spraying member, a connecting rod, a driving block and a water inlet pipe; a spraying member is arranged inside the tower body above the coil pipe, the spraying member includes a bearing cylinder and a bearing ring, the bearing ring is rotatably connected to the peripheral wall of the tower body and a bearing cylinder is arranged at the center, spraying pipes are annularly arranged on the peripheral wall of the bearing cylinder, the outer end of each spraying pipe is connected to the bearing ring and the inner end is communicated with the bearing cylinder, the connecting rod penetrates through and is fixedly connected to the top plate of the bearing cylinder, and fan blades are annularly arranged at the upper end of the peripheral wall of the connecting rod; the driving block is a spherical segment with a convexity facing downward, the lower end of the connecting rod is located inside the bearing cylinder and is connected to the top surface of the driving block, grooves are annularly arranged on the spherical surface of the driving block, one end of each groove is close to the lower end of the spherical surface of the driving block and the other end penetrates through the edge of the spherical surface of the driving block, and the ends of the multiple grooves on the driving block penetrating through the edge of the spherical surface of the driving block all incline in the same direction, and the water outlet end of the water inlet pipe penetrates through and is rotatably connected to the bottom plate of the bearing cylinder.

[0007] Furthermore, both the water inlet end and the water outlet end of the coil pipe are located outside the tower body, a drain pipe is communicated with the lower end of the peripheral wall of the tower body, the air inlet holes are located between the coil pipe and the drain pipe, and multiple supporting legs are arranged on the outer bottom surface of the tower body; spraying holes are arranged at intervals on the lower end of the peripheral wall of the spraying pipe.

[0008] Furthermore, a connecting cylinder is provided at the upper end of the tower body. The connecting cylinder penetrates and is fixedly connected to the top plate of the tower body. The upper end of the connecting rod extends into the connecting cylinder, and multiple fan blades on the connecting rod are located inside the connecting cylinder.

[0012] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] After the hot water enters the bearing cylinder in the present utility model, the hot water impacts the driving block to drive the bearing cylinder to rotate.

Specific embodiments

[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0022] As Figures 1 to 5 shown, an energy-saving cooling tower includes a tower body 1. The tower body 1 is a cylinder with an open lower end blocked by a bottom plate. A coil pipe 2 is arranged inside the tower body 1. An air inlet hole 3 is arranged on the peripheral wall of the tower body 1 below the coil pipe 2. It also includes a spraying member, a connecting rod 4, a driving block 5 and a water inlet pipe 6. A spraying member is arranged inside the tower body 1 above the coil pipe 2. The spraying member includes a bearing cylinder 7 and a bearing ring 8. The bearing ring 8 is an annular body with an outer diameter matching the inner diameter of the tower body 1. The bearing ring 8 is rotatably connected to the peripheral wall of the tower body 1 and a bearing cylinder 7 is arranged at the center. The bearing cylinder 7 is a cylindrical body with an open upper end blocked by a top plate. Spray pipes 9 are annularly arranged on the peripheral wall of the bearing cylinder 7. The outer end of each spray pipe 9 is connected to the bearing ring 8 and the inner end communicates with the bearing cylinder 7. The connecting rod 4 is a round rod. The connecting rod 4 penetrates and is fixedly connected to the top plate of the bearing cylinder 7. Fan blades 10 are annularly arranged at the upper end of the peripheral wall of the connecting rod 4. The driving block 5 is a spherical segment with a convexity facing downwards. The lower end of the connecting rod 4 is located inside the bearing cylinder 7 and is connected to the top surface of the driving block 5. The top surface of the driving block 5 is a straight surface. Grooves 11 are annularly arranged on the spherical surface of the driving block 5. The groove is a long strip-shaped groove. One end of each groove 11 is close to the lower end of the spherical surface of the driving block 5 and the other end penetrates the edge of the spherical surface of the driving block 5. The ends of the multiple grooves 11 on the driving block 5 that penetrate the edge of the spherical surface of the driving block 5 all incline in the same direction. The water outlet end of the water inlet pipe 6 penetrates and is rotatably connected to the bottom plate of the bearing cylinder 7. The water outlet end of the water inlet pipe 6 penetrates the peripheral wall of the tower body 1 and is located inside the tower body 1.

[0023] Both the water inlet end and the water outlet end of the coil pipe 2 are located outside the tower body 1. A drain pipe 12 is communicated with the lower end of the peripheral wall of the tower body 1. The air inlet hole 3 is located between the coil pipe 2 and the drain pipe 12. A valve 13 is arranged on the drain pipe 12. Multiple support legs 14 are arranged on the outer bottom surface of the tower body 1. Spray holes 16 are arranged at intervals on the lower end of the peripheral wall of the spray pipe 9.

[0024] At the upper end of the tower body 1, there is a connecting cylinder 17. The connecting cylinder 17 is a cylindrical tube with both ends open and an outer diameter smaller than the inner diameter of the tower body 1. The connecting cylinder 17 penetrates and is fixedly connected to the top plate of the tower body 1. The upper end of the connecting rod 4 extends into the connecting cylinder 17, and multiple fan blades 10 on the connecting rod 4 are located inside the connecting cylinder 17. A cross plate 18 is provided inside the connecting cylinder 17, and the connecting rod 4 movably penetrates the cross plate 18.

[0025] An annular groove 19 is provided on the outer ring surface of the bearing ring 8. The opening of the annular groove 19 faces the inner wall of the tower body 1. A limiting rod 20 is provided on the tower body 1. One end of the limiting rod 20 penetrates the peripheral wall of the tower body 1 and extends into the annular groove 19. The limiting rod 20 is fixedly connected to the peripheral wall of the tower body 1, and the annular groove 19 is in sliding contact with one end of the limiting rod 20 extending into the annular groove 19.

[0026] Limiting rings 21 are sleeved on the outer walls of the water inlet pipes 6 on both the upper and lower sides of the bottom plate of the bearing cylinder 7. Both limiting rings 21 are in sliding contact with the bottom plate of the bearing cylinder 7. A connecting rod 22 is connected between the water inlet pipe 6 and the inner wall of the tower body 1, and the connecting rod 22 can ensure the stability of the water inlet pipe 6.

[0027] The top surface diameter of the driving block 5 is smaller than the inner diameter of the bearing cylinder 7, and the lower spherical surface of the driving block 5 and the center of the water outlet end of the water inlet pipe 6 are relatively positioned up and down.

[0028] During use, open the valve 13 on the drain pipe 12. Cooling water flows in the coil 2. The hot water to be cooled flows into the bearing cylinder 7 through the water inlet pipe 6. The hot water discharged from the water outlet end of the water inlet pipe 6 impacts the groove 11 on the spherical surface of the driving block 5. Since multiple grooves 11 are inclined, under the pressure of the hot water discharged from the water inlet pipe 6, it can drive the driving block 5 to drive the bearing cylinder 7 to rotate. The hot water in the bearing cylinder 7 enters multiple spray pipes 9 and is sprayed downward through the spray holes 16 on the spray pipes 9 towards the coil 2. The hot water contacts the coil 2, and the cooling water in the coil 2 cools the hot water sprayed towards the coil 2. Moreover, after the hot water impacts the driving block 5, the driving block 5 drives the bearing cylinder 7 to rotate through the connecting rod 4. The bearing ring 8 is rotatably connected to the tower body 1, and multiple spray pipes 9 on the spraying member rotate with the driving block 5. Therefore, the cooling water sprayed from the spray pipes 9 can rotate circumferentially while spraying downward, so that the hot water sprayed from the spray pipes 9 can contact the coil 2 more, thereby improving the cooling efficiency and achieving a certain energy-saving effect.

[0029] When the connecting rod 4 rotates with the bearing cylinder 7, multiple fan blades 10 on the connecting rod 4 rotate with the connecting rod 4, which can drive the air in the tower body 1 to be discharged through the connecting cylinder 17. The cold air from the outside enters the tower body 1 through the air inlet holes 3. Thus, the air drives the heat of the hot water in the tower body 1 to be discharged through the connecting cylinder 17, promoting the cooling of the hot water. Moreover, the rotation of multiple fan blades 10 on the connecting rod 4 is realized under the impact of the hot water, without an additional motor and without using electricity, saving costs and energy.

[0030] After the hot water is cooled, it enters the lower part of the tower body 1 and is discharged through the drain pipe 12.

[0031] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Without departing from the spirit of the present utility model, that is, within the scope of disclosure, any equivalent or equivalent deformation or replacement of the technical solutions of the utility model belongs to the protection scope of the present utility model.
