Description

Technical Field

[0001] The utility model relates to a water distribution nozzle, in particular to a water distribution nozzle for a cooling tower. Background Art

[0002] The water distribution nozzle of the cooling tower is usually connected to the water supply pipe at the top of the cooling tower. After the cooling water enters the water distribution nozzle, it will splash out from the surroundings and cool the filler inside the cooling tower.

[0003] Existing cooling tower water distribution nozzles, such as the one disclosed in Chinese patent CN214470345U, can realize adaptive water outlet pressure regulation to maintain the water outlet pressure of the water distribution pipe in real time. When the water inlet pressure is relatively low, it can still maintain the effect of the splashing range of cooling water. However, when in use, it is directly fixedly connected to the water supply pipe at the top of the cooling tower and cannot be moved during the water spraying process. Therefore, the water distribution range is small and the water flow is unevenly distributed, resulting in poor cooling effect on the cooling tower filler. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the utility model provides a cooling tower water spray nozzle.

[0005] The utility model overcomes the above technical problems by adopting the following technical solutions, specifically:

[0007] Wherein, a mounting assembly is arranged on the connecting tube, the top end of the rotating shaft extends out of the outside of the Z-shaped sleeve and a driving assembly is arranged between the connecting tube.

[0008] As a further solution of the utility model: the installation assembly includes a threaded pipe head arranged at the end of the connecting pipe, a clamping ring sleeved around the threaded pipe head, and a sealing ring arranged on the clamping ring.

[0009] As a further solution of the utility model: the driving assembly includes a gear sleeved on the top end of the rotating shaft, and a gear ring arranged around the gear and meshing with the gear;

[0010] Wherein, the connecting pipe is aligned with the center of the gear ring.

[0011] As a further solution of the utility model: the gear ring is fixedly connected to the outer wall of the connecting pipe through multiple groups of suspension rods.

[0012] As a further solution of the utility model: a plurality of groups of water tanks are arranged in a stepped manner inside the water spray head, and the water outlets are distributed around the water tanks.

[0013] As a further solution of the utility model: the connecting pipe and the Z-shaped sleeve are rotatably connected via a waterproof bearing, and the top end of the rotating shaft and the outer wall of the Z-shaped sleeve are rotatably connected via a waterproof bearing.

[0014] After adopting the above structure, the utility model has the following advantages compared with the prior art: through the joint action of the Z-shaped sleeve, the sprinkler head, the rotating shaft, the impeller, the driving assembly, etc., during the process of water flowing out from the water outlet on the sprinkler head, the Z-shaped sleeve drives the sprinkler head to perform a circular motion, and at the same time the sprinkler head will rotate so that the cooling water can be sprayed farther, thereby making the water distribution range wider and improving the uniformity of the water distribution, thereby improving the cooling effect on the internal filler of the cooling tower.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4In an embodiment of the utility model, a cooling tower water spray head comprises a connecting pipe 1, one end of the connecting pipe 1 is rotatably connected to a Z-shaped sleeve 2, one end of the Z-shaped sleeve 2 is nested with a spray head 3, a water outlet 4 is arranged on the spray head 3, a rotating shaft 5 is arranged inside the Z-shaped sleeve 2, an impeller 6 is sleeved on the rotating shaft 5, the top end of the rotating shaft 5 is rotatably connected to the outer wall of the Z-shaped sleeve 2, and the bottom end of the rotating shaft 5 is fixedly connected to the spray head 3;

[0022] Wherein, a mounting assembly is provided on the connecting pipe 1, and a driving assembly is provided between the top end of the rotating shaft 5 extending out of the Z-shaped sleeve 2 and the connecting pipe 1;

[0023] The connecting pipe 1 can be installed and connected to the end of the water supply pipe at the top of the cooling tower through the installation component. At this time, the water flowing out of the water supply pipe can flow from the connecting pipe 1 to the inside of the Z-shaped sleeve 2, and flow to the sprinkler head 3 at the other end of the Z-shaped sleeve 2, and finally sprayed out from the water outlet 4 on the sprinkler head 3 and sprinkled on the cooling tower filler. When the water flows through the impeller 6 in the Z-shaped sleeve 2, the impeller 6 can rotate under the impeller 6. Then, the shaft 5 will rotate under the drive of the impeller 6. During the rotation of the shaft 5, the driving component will drive the Z-shaped sleeve 2 to perform a circular motion as a whole, thereby increasing the cooling effect. The coverage range of the water flow sprayed from the water outlet 4 also makes the water flow more evenly distributed in the cooling tower. In addition, the rotation of the shaft 5 will drive the water spray head 3 to rotate. When the water flow in the Z-shaped sleeve 2 flows into the water spray head 3, the water spray head 3 will rotate so that the water flowing into it is subjected to centrifugal action. The water sprayed from the water outlet 4 will be sprayed farther under the centrifugal action, further increasing the coverage range of the water flow. In summary, compared with traditional water distribution nozzles, this structure has a wider water distribution range and improves the uniformity of water distribution, thereby improving the cooling effect on the internal filler of the cooling tower.

[0024] In one embodiment of the utility model, the installation assembly includes a threaded pipe head 7 provided at the end of the connecting pipe 1, a clamping ring 8 sleeved around the threaded pipe head 7, and a sealing ring 9 provided on the clamping ring 8;

[0025] By twisting the threaded pipe head 7, it can be conveniently connected with the threaded end of the water supply pipe at the top of the cooling tower. When the threaded pipe head 7 is twisted to make the clamping ring 8 fit with the end of the water supply pipe, the sealing ring 9 can seal the joint between the threaded pipe head 7 and the end of the water supply pipe to prevent water from leaking from the joint between the threaded pipe head 7 and the end of the water supply pipe.

[0026] In another embodiment of the utility model, the driving assembly includes a gear 10 sleeved on the top of the rotating shaft 5, and a gear ring 11 disposed around the gear 10 and meshing with the gear 10;

[0027] Wherein, the connecting pipe 1 is aligned with the center of the gear ring 11;

[0028] The rotation of the rotating shaft 5 will drive the gear 10 at its top to rotate. Due to the meshing relationship between the gear 10 and the gear ring 11, the gear 10 will be driven by the gear ring 11 and move along the gear ring 11 while rotating. Since the Z-shaped sleeve 2 is rotatably connected to one end of the connecting tube 1, and the connecting tube 1 is aligned with the center of the gear ring 11, the Z-shaped sleeve 2 as a whole will also perform a circular motion along the direction of the gear ring 11 under the drive of the gear 10.

[0029] In another embodiment of the utility model, the gear ring 11 is fixedly connected to the outer wall of the connecting pipe 1 through multiple groups of suspension rods 12;

[0030] The multiple groups of suspension rods 12 can firmly connect the gear ring 11 to the connecting pipe 1 , so that the gear ring 11 can remain stable and not easily deformed under the action of external force, thereby ensuring that the Z-shaped sleeve 2 as a whole can stably perform circular motion along the gear ring 11 .

[0031] In another embodiment of the utility model, the water spray head 3 is provided with multiple groups of water tanks 13 in a stepped manner, and the water outlets 4 are distributed around the water tanks 13;

[0032] The water flowing into the sprinkler head 3 from the Z-shaped sleeve 2 will be evenly divided into multiple streams and flow into the multi-component water troughs 13 respectively. The diameters of the multi-component water troughs 13 arranged in a stepped manner are all different, so the falling ranges of the water flows sprayed from the multi-stream water troughs 13 will also be different, thereby increasing the dispersion of the water flow sprayed from the water outlet 4 and making the water distribution more uniform.

[0033] In another embodiment of the utility model, the connecting pipe 1 is rotatably connected to the Z-shaped sleeve 2 via a waterproof bearing, and the top end of the rotating shaft 5 is rotatably connected to the outer wall of the Z-shaped sleeve 2 via a waterproof bearing;

[0034] The waterproof bearing allows the Z-shaped sleeve 2 to rotate at the end of the connecting pipe 1, while preventing water from seeping out from the joint between the connecting pipe 1 and the Z-shaped sleeve 2. Similarly, the waterproof bearing between the Z-shaped sleeve 2 and the rotating shaft 5 allows the rotating shaft 5 to rotate in the Z-shaped sleeve 2, while preventing water in the Z-shaped sleeve 2 from seeping out from the joint between the Z-shaped sleeve 2 and the rotating shaft 5.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
