Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water distribution device for cooling towers. Background Art

[0002] A cooling tower uses a water pump to pump water to the top of the tower, where it is evenly distributed through a water distribution system. Simultaneously, large exhaust fans above the tower create wind to draw air away. As the air and water droplets come into contact, heat is removed, cooling the water.

[0003] The water pipes of the cooling tower water distribution device are provided with multiple water holes, through which water droplets are transported into the tower body. However, when the cooling tower is in use, the power will need to be adjusted and changed. The amount of cooling water required by the cooling tower at different powers is different. The diameter of the water holes on the existing water distribution device is fixed, and the amount of water flowing out of the water holes cannot be controlled, which easily leads to waste of water resources. Summary of the Invention

[0004] The utility model solves the problem that the water distribution device of the cooling tower is difficult to adjust the water output according to the power of the cooling tower, and provides a water distribution device for a cooling tower, which can conveniently adjust the water output of the water distribution device and reduce the waste of water resources.

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

[0006] A water distribution device for a cooling tower comprises a main water pipe, a branch water pipe, a driving ring and an adjusting member; the main water pipe is provided with a circular array of branch water pipes, the inner end of each branch water pipe is connected to the main water pipe, and the lower end of the peripheral wall of each branch water pipe is provided with water outlet holes at intervals, the outer ends of multiple branch water pipes are connected together and are sleeved on the bearing ring outside the main water pipe, and the external threads of the main water pipes on the upper sides of multiple branch water pipes are connected to the driving ring; each branch water pipe is provided with an adjusting member, and the adjusting member comprises an arc plate, a connecting ring and a torsion spring, the arc plate is slidably sleeved on the outside of the corresponding branch water pipe, the lower end opening of the arc plate covers the outside of the multiple water outlet holes at the lower end of the corresponding branch water pipe, the outer end of the arc plate and the bearing ring are connected with a torsion spring, and the inner end is connected to a connecting ring rotatably arranged outside the branch water pipe, and a steel strand is provided on the connecting ring, one end of the steel strand is fixedly connected to the connecting ring, and the other end is wrapped around the connecting ring and then connected to the bottom surface of the driving ring.

[0007] Furthermore, an external thread is provided on the outer wall of the main water pipe, and an internal thread corresponding to the external thread is provided on the inner ring of the driving ring.

[0008] Furthermore, a limiting bolt is threadedly connected to the driving ring, and a free end of the limiting bolt contacts the outer wall of the main water pipe.

[0009] Furthermore, the cross-section of the arc plate is an arc-shaped, the inner and outer ends of the arc plate are arc-shaped, and the inner side surface of the arc plate slides in contact with the outer wall of the corresponding branch water pipe; the inner and outer ends and the lower end of the arc plate are open, and the width of the lower end opening of the arc plate is greater than the diameter of the water outlet hole; when the lower end opening of the arc plate is covered outside the multiple water outlet holes at the lower end of the corresponding branch water pipe, the torsion spring connected to the arc plate is in a natural state.

[0013] When the torsion spring outside the branch water pipe is in a natural state, the water output of the multiple branch water pipes is at its maximum. By driving the driving ring to move upward, the driving ring can pull the connecting ring outside each branch water pipe to rotate via the steel strand. When the connecting ring rotates, it can drive the connected arc plate to rotate. When the arc plate rotates, it gradually covers the water outlet hole, so that the water output of the water outlet hole gradually decreases, thereby controlling the water output of the utility model, facilitating adjustment, and reducing water waste.

[0014] When the driving ring of the utility model moves downward, the arc plate can return to its initial state under the restoring force of the torsion spring, and the water output of the branch water pipe corresponding to the arc plate can be readjusted to the maximum water output.

The inner end of each branch water pipe 2 is connected to the main water pipe 1, and the lower end of the peripheral wall of each branch water pipe 2 is provided with a water outlet hole 4 at intervals, and the water outlet hole 4 is a circular hole body. The outer ends of multiple branch water pipes 2 are connected together and are sleeved on the supporting ring 5 outside the main water pipe 1. The supporting ring 5 is a circular ring body. The main water pipe 1 on the upper side of multiple branch water pipes 2 is externally threaded with a driving ring 3. The driving ring 3 is a circular ring; each branch water pipe 2 is provided with an adjusting part, and the adjusting part includes an arc plate 6, a connecting ring 7 and a torsion spring 8. The arc plate 6 is slidably sleeved on the outside of the corresponding branch water pipe 2, and the lower end opening of the arc plate 6 is covered outside the multiple water outlet holes 4 at the lower end of the corresponding branch water pipe 2. The outer end of the arc plate 6 and the bearing ring 5 are connected with a torsion spring 8, and the inner end is connected to the connecting ring 7 rotatably arranged outside the branch water pipe 2. The outer end of the arc plate 6 is one end facing the bearing ring 5, and the inner end is one end facing the main water pipe 1. A steel strand 9 is provided on the connecting ring 7, one end of the steel strand 9 is fixedly connected to the connecting ring 7, and the other end is wrapped around the connecting ring 7 and connected to the bottom surface of the driving ring 3.

[0024] An external thread 10 is provided on the outer wall of the main water pipe 1 , and an internal thread corresponding to the external thread 10 is provided on the inner ring of the driving ring 3 .

[0025] A limiting bolt 11 is threadedly connected to the driving ring 3 , and a free end of the limiting bolt 11 contacts the outer wall of the main water pipe 1 .

[0026] The cross-section of the arc plate 6 is an arc shape, the inner and outer ends of the arc plate 6 are arc-shaped, and the inner side surface of the arc plate 6 slides in contact with the outer wall of the corresponding branch water pipe 2; the inner and outer ends and the lower end of the arc plate 6 are open, and the width of the lower end opening of the arc plate 6 is greater than the diameter of the water outlet hole 4; when the lower end opening of the arc plate 6 is covered outside the multiple water outlet holes 4 at the lower end of the corresponding branch water pipe 2, the torsion spring 8 connected to the arc plate 6 is in a natural state.

[0027] The torsion spring 8 connected to the outer end of the arc plate 6 is sleeved outside the branch water pipe 2 corresponding to the arc plate 6.

[0028] The connecting ring 7 is a circular ring body, and the inner ring of the connecting ring 7 is rotatably connected to the outer wall of the corresponding branch water pipe 2 through the bearing 13; an annular groove 12 is provided on the outer ring surface of the connecting ring 7, and one end of the steel strand 9 corresponding to the connecting ring 7 is fixedly connected to the bottom surface of the annular groove, and the other end is wound in the annular groove 12 and then connected to the driving ring.

[0029] When in use, the supporting ring 5 of the present invention is fixedly connected to the inner wall of the cooling tower, and the upper end opening of the main water pipe 1 is connected to the water inlet pipe. When the torsion springs 8 outside the multiple branch water pipes 2 are in a natural state, the lower end opening of the arc plate 6 outside the branch water pipe 2 is covered outside the multiple water outlet holes 4 on the branch water pipe 2, and the water outlet holes 4 on the branch water pipe 2 are not blocked. At this time, the water outlet holes 4 on the multiple branch water pipes 2 of the present invention have a maximum water outflow; when it is necessary to reduce the water outflow of the water outlet holes 4 on the branch water pipe 2, loosen the limit bolt 11 so that the free end of the limit bolt 11 no longer presses against the outer wall of the main water pipe 1, rotate the drive ring 3, and make the drive ring 3 move upward. The drive ring 3 moves upward, pulling the connected steel strand 9 and the end connected to the drive ring 3 to move upward, each steel strand 9 pulls the connected connecting ring 7 to rotate, and each connecting ring 7 drives the The connected arc plate 6 rotates, and the torsion spring 8 connected to the arc plate 6 is twisted. In the process of the arc plate 6 rotating along the peripheral wall of the corresponding branch water pipe 2, the peripheral wall of the arc plate 6 gradually covers and blocks the water outlet 4 at the lower end of the corresponding branch water pipe 2. As the arc plate 6 rotates, the covering area of the water outlet 4 on the corresponding branch water pipe 2 by the arc plate 6 changes from small to large. Therefore, the water outlet of the branch water pipe 2 gradually changes from large to small. According to the upward movement stroke of the driving ring 3, the rotation angle of the arc plate 6 can be controlled, the area covered by the arc plate 6 on the water outlet 4 can be controlled, and the water outlet of the branch water pipe 2 can be controlled. After the water outlet of the branch water pipe 2 is adjusted, the limit bolt 11 is tightened so that the free end of the limit bolt 11 is pressed against the outer wall of the main water pipe 1, thereby limiting the driving ring 3 to prevent the driving ring 3 from rotating due to external force, thereby preventing the water outlet of the branch water pipe 2 from changing.

[0030] Moreover, when the driving ring 3 is driven to move downward, the multiple arc plates 6 can return to the initial state under the restoring force of the torsion spring 8, and the water output of the branch pipe 2 corresponding to the arc plate 6 can be readjusted to the maximum water output.

[0031] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Without violating the spirit of the present invention, that is, within the scope of disclosure, any equivalent or equivalent deformation or replacement of the technical solution of the utility model shall fall within the scope of protection of the present invention.
