[0022] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, device, product or end that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or ends.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The utility model discloses a specific implementation of a sliding inspection door for a cooling tower. Figures 1 to 6 The sliding inspection door for cooling tower comprises a panel 1, a pair of guide rails 2 and an inspection door 3. It should be noted that the panel 1 is a part of the outer shell of the cooling tower, which can be formed by splicing a plurality of sheet metals.

[0026] As an improvement, see Figure 2 The panel 1 is provided with an inspection window 11 , and a pair of guide rails 2 are fixedly installed on the upper and lower sides of the inspection window 11 . The guide rails 2 can be fixed to the panel 1 by screws, and the inspection door 3 is inserted between the pair of guide rails 2 .

[0027] In this embodiment, a sliding assembly 4 is provided on the lower side of the inspection door 3 and is placed in the guide rail 2, so that the inspection door 3 can slide along the guide rail 2 and cover the inspection window 11. Figure 3 and Figure 4The sliding assembly 4 includes a pulley seat 41, a locking bolt 43 and a plurality of pulleys 42. Each pulley 42 can be rotatably mounted on the pulley seat 41. Specifically, a transfer hole can be provided on the pulley seat 41, and the pulley 42 can be rotatably mounted on the pulley seat 41 with a rotating shaft or an axle pin. A threaded hole 44 is provided in the middle of the top surface of the pulley seat 41, and a through hole 31 is provided at the bottom of the inspection door 3. In the assembled state, the locking bolt 43 passes through the through hole 31 and is threadedly connected with the threaded hole 44 of the pulley seat 41, so that the sliding assembly 4 can be fixedly mounted on the lower side of the inspection door 3. It should be noted that in this embodiment, the sliding assembly 4 is not provided on the upper side of the inspection door 3. It only needs to set the guide rail 2 located on the upper side of the inspection window 11 so that the inspection door 3 can be inserted and slid. Specifically, the sliding of the inspection door 3 can be achieved by providing a groove 21 with a thickness equal to or greater than the thickness of the inspection door 3. In other embodiments, a corresponding sliding assembly 4 is also provided on the upper side of the inspection door 3, that is, at least two sliding assemblies 4 are provided, which can improve the structural strength and the sliding smoothness of the inspection door 3. In addition, the inspection door 3 may not be provided with a sliding assembly 4, but this will cause the inspection door 3 to slide less smoothly, but the inspection door 3 can also slide along the guide rail 2.

[0028] To improve safety, combine Figure 1 and Figure 5 The side of the inspection door 3 is provided with a locking assembly that is locked with the panel 1. Optionally, the locking assembly includes a movable handle 51 and a lock tongue 52. A lock hole (not shown) is provided on one side of the panel 1 facing the locking assembly. One end of the lock tongue 52 is fixedly connected to the handle 51, and the other end of the lock tongue 52 passes through the side of the inspection door 3. When locking, the handle 51 rotates to drive the lock tongue 52 to move, so that the lock tongue 52 is stuck in the lock hole. When unlocking, the handle 51 is rotated, and the handle 51 drives the lock tongue 52 to rotate and escape from the lock hole, so that the inspection door 3 can be unlocked. The specific structure of the handle 51 and the lock tongue 52 can adopt the conventional lock structure on the market.

[0029] In this example, see Figure 6 The end surface of the guide rail 2 facing the inspection door 3 is formed with a groove 21 for the sliding assembly 4 to be placed. As a preferred solution, the cross-sectional shape of the guide rail 2 is set in a concave shape. The guide rail 2 of this structure has low cost and strong structural strength. The guide rail 2 of this structure can be formed by bending sheet metal, or directly using finished profiles or channel steels for cutting to obtain the guide rail 2 of this structure. The production is very simple and the production cost is low.

[0030] In addition, in order to facilitate the assembly and fixation of the guide rail 2, the front and rear ends of the guide rail 2 extend out connecting parts 22 in the vertical direction. Self-tapping screws are used to pass through the connecting parts 22 and threadedly connect with the panel 1 to complete the assembly of the guide rail 2, and the construction is very convenient.

[0031] Compared with the prior art, the sliding inspection door for a cooling tower in the present embodiment is provided with a guide rail 2 and a sliding assembly 4 so that the inspection door 3 can slide horizontally in the lateral direction. The inspection door 3 is opened and closed by horizontal sliding, replacing the previous hinged installation method. The structure is simple and compact, and there is no need to occupy the space inside and outside the cooling tower. It is more convenient to inspect the cooling tower, solving the problem of inconvenience in use in the past.

[0032] Finally, it should be noted that the sliding inspection door for a cooling tower disclosed in the embodiment of the utility model is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
