Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and specifically discloses a cooling tower water distribution device. Background Art

[0002] The water distributor of the cooling tower is equipped with a water distribution pipe in a circular array of the diverter seat, and a nozzle is arranged at the bottom of the water distribution pipe. The water flowing into the water distribution pipe from the diverter seat is sprayed out from the nozzle in a mist form and sprayed onto the glass fiber filler below. Since the water distribution pipe is a metal pipe, it is long and heavy. The connection between the water distribution pipe and the diverter seat flange is a fulcrum. There is a large bending moment at this fulcrum, so a pipe hanging column is generally set at the top of the diverter seat, and a steel wire rope is set between the end of the water distribution pipe and the top of the pipe hanging column. The steel wire rope provides tension to pull the water distribution pipe to reduce the bending moment at the flange connection, as shown in the cooling tower water distributor disclosed in application number CN202220443307.9. However, after long-term use, the wire rope is easily deformed due to fatigue under the action of the water distribution pipe and water, causing the water distributor to weaken the oblique upward pulling force on the far end of the water distribution pipe. The far end of the water distribution pipe is prone to sinking, resulting in a reduction in the water distribution area. In severe cases, the far end of the water distribution pipe may come into direct contact with the filler, affecting uniform water distribution. Utility Model Content

[0003] The utility model aims to solve the above-mentioned problem and provides a cooling tower water distribution device, which can adjust the tension of the wire rope on the water distribution pipe to a certain extent to prevent the far end of the water distribution pipe from sinking.

[0005] The fixing assembly includes a connecting column, a spring and a buckle plate mounted on the connecting column; the buckle plate is located above the spring, and the steel wire rope is connected to the buckle plate; the buckle plate presses the spring downward to put the spring in a compressed state; when the steel wire rope is loose, the spring can push the buckle plate upward to restore the steel wire rope to a tensioned state.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment discloses a cooling tower water distribution device, which includes a water distributor 4 and a plurality of water distribution pipes 2 circumferentially evenly connected to the water distributor 4. The water distributor 4 is connected to the water inlet pipe 1, and after the water enters the water distributor 4 from the water inlet pipe 1, it is evenly distributed to each water distribution pipe 2. The water distribution pipe 2 is provided with a plurality of nozzles along its length direction, and the water entering the water distribution pipe 2 is evenly sprayed out from the nozzles.

[0029] like Figure 3 As shown, a separation cylinder 11 is provided inside the water distributor 4; the upper end of the separation cylinder 11 abuts against the top of the water distributor 4, and the lower end thereof is connected to the water inlet pipe 1. A plurality of connecting flanges 14 are circumferentially provided on the side wall of the water distributor 4, and the connecting flanges 14 are connected to the water distribution pipe 2, and one connecting flange 14 corresponds to one water distribution pipe 2.

[0030] In addition, a separation chamber 13 is formed between the separation cylinder 11 and the inner wall of the water distributor 4, and the connecting flange 14 is connected to the separation chamber 13. In addition, a plurality of water holes 12 connected to the separation chamber 13 are evenly arranged around the upper end of the separation cylinder 11. Water enters the separation cylinder 11 from the water inlet pipe 1. When the water flows upward through the water holes 12, it evenly enters the separation chamber 13 from the water holes 12, and then evenly distributes to each water distribution pipe 2, so that the water distribution is more even. At the same time, the water holes 12 can also play a filtering role.

[0031] A fixed structure is arranged above the water distributor 4, and the fixed structure is provided with the same number of fixed components as the number of the water distribution pipes 2, and a steel wire rope 3 is connected between the fixed components and the distal end of the water distribution pipes 2. Figure 1 shown.

[0032] Among them, the fixed structure includes a pipe hanging column 5 arranged on the water distributor 4, a lower fixed plate 6 arranged on the top of the pipe hanging column 5, and an upper fixed plate 7 arranged above the lower fixed plate 6; the upper and lower ends of the fixed component are respectively fixed on the upper fixed plate 7 and the lower fixed plate 6.

[0033] Specifically, Figure 2 As shown, the fixing assembly includes a connecting column 8 whose upper and lower ends are respectively fixed on the upper fixing plate 7 and the lower fixing plate 6, and a spring 9 and a buckle plate 10 sleeved on the connecting column 8. The buckle plate 10 is located above the spring 9, and the steel wire rope 3 is connected to the buckle plate 10.

[0034] The buckle plate 10 is mounted on the connecting column 8 via a linear bearing, so the buckle plate 10 can move up and down along the connecting column 8 smoothly.

[0035] A limiting rod 15 is provided between the lower fixing plate 6 and the upper fixing plate 7 , and the limiting rod 15 passes through the buckle plate 10 , thereby preventing the buckle plate 10 from rotating.

[0036] In addition, the fixing position of the wire rope 3 needs to ensure that the vertical projection of the wire rope 3 coincides with the axis of the water distribution pipe 2, which can improve the stability of the device.

[0037] During initial installation, the wire rope 3 is in a taut state, and it pulls the buckle plate 10 downward obliquely, and the buckle plate 10 presses the spring 9 downward, so that the spring 9 is in a compressed state. At this time, the wire rope 3 also pulls the far end of the water distribution pipe 2 upward obliquely to prevent the far end of the water distribution pipe 2 from sinking. When the wire rope 3 is relaxed, the tension on the wire rope 3 becomes weak, and the spring 9 pushes the buckle plate 10 upward, so that the wire rope 3 resumes the taut state and continues to apply tension to the water distribution pipe 2.

[0038] Example 2

[0039] This embodiment is based on the embodiment 1, and a contact sensor (not shown in the figure) is arranged on the lower surface of the upper fixing plate 7, and the contact sensor is connected to the external alarm system. When the wire rope 3 is too loose, the buckle plate 10 is pushed upward and contacts the contact sensor, which indicates that the upward thrust of the spring 9 may be insufficient, and the pulling force of the wire rope 3 on the water distribution pipe 2 is insufficient. The contact sensor sends a signal to the alarm system, and the alarm system sounds an alarm to remind the workers to perform maintenance in advance.

[0040] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0041] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
