[0008] A further improvement of the cooling tower nozzle structure of the utility model is that a sealing gasket is fixedly provided on the upper end surface of the fixing portion, and the lower end of the adjustment plate abuts against the sealing gasket.

[0009] The utility model provides a further improvement on the structure of a cooling tower nozzle in that a through slot is provided in the middle of the adjustment plate, and when the adjustment plate is in place, the length direction of the through slot is the same as the length direction of the spray pipe.

[0010] The utility model provides a further improvement on the structure of a cooling tower nozzle in that a strip-shaped adjustment mark is provided on the upper end of the adjustment plate, and the length direction of the strip-shaped adjustment mark is the same as the length direction of the through-groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Figure 1 It is a structural diagram of the utility model;

[0014] In the figure: 1 spray pipe, 2 fixing plate, 3 fixing part, 4 spray head, 5 second fixing plate, 6 adjustment plate, 7 sealing gasket. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] like Figure 1 As shown, a cooling tower nozzle structure includes a spray pipe 1 fixedly connected to the side wall of the cooling tower, a cylindrical hollow fixing plate 2 is provided on the lower end surface of the spray pipe, a spray head 4 is connected to the lower end of the fixing plate, and a second fixing plate 5 is provided on the upper end surface of the spray pipe. The number of the second fixing plates is half the number of the fixing plates, and the second fixing plates are arranged directly above a fixing plate with a spray head spaced apart. The second fixing plate is provided with an adjusting member for extending into the fixing plate and blocking the fixing plate.

[0017] A fixing portion 3 is provided on the inner sidewall of the lower portion of the fixing plate. This portion is provided with a first thread and is threadedly connected to the sprinkler head. A sealing gasket 7 is fixed to the upper end of the fixing portion, against which the lower end of the adjustment plate abuts. This results in an L-shaped cross-section of the fixing plate, which, in combination with the sealing gasket, further enhances sealing performance, thereby ensuring effective water flow regulation.

[0018] Furthermore, the adjusting member is an adjusting plate 6 with a T-shaped cross section, the inner side wall of the second fixing plate and the upper part of the inner side wall of the fixing plate are provided with a second thread, and the adjusting plate is provided with a connecting thread adapted to the second thread.

[0019] Furthermore, a through-groove (not shown) is provided in the middle of the adjustment plate. When the adjustment plate is in place, the length of the through-groove aligns with the length of the spray pipe. A bar-shaped adjustment mark is provided at the top of the adjustment plate, and its length aligns with the through-groove. The through-groove ensures proper spraying operation of the entire spray pipe structure.

[0020] In another embodiment, the adjusting member can be directly a T-shaped plate. In this case, the second fixing plate and the inner side of the fixing plate are not threaded, and the adjusting member is directly plugged into and sealed between the second fixing plate and the fixing plate. A connecting rod can be provided in the external position to connect multiple adjusting members and have a drive structure to achieve overall vertical movement for easy control.

[0021] The working principle of the present invention is: when it is necessary to reduce the water spraying amount, the water intake cannot be directly controlled to be reduced, otherwise the spraying amount of the distal spray head will be reduced relative to the proximal spray head, which will cause uneven spraying heat exchange. Then, the control adjustment part is controlled to block the interval spray heads to achieve the reduction of the spraying amount while ensuring uniform spraying, which is conducive to the realization of cooling and heat exchange in the cooling tower.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
