Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a pull-out pre-spreader installation structure. Background Technology

[0002] Existing cooling towers all have a water inlet end, see Figure 1 , Figure 1 This is a schematic diagram of the structure of the inlet of a cooling tower in the prior art. The structure of the inlet end 11 includes a cover plate assembly, a pre-spreader 13, and a water distribution basin 14 arranged sequentially along the water flow direction. Multiple spaced-apart bottom nozzles 15 are fixedly installed on the water distribution basin 14. The cover plate assembly includes multiple baffles 16 and an inlet cover 12. The pre-spreader 13 is fixedly installed on the bottom of the inlet cover 12 by multiple screws 17, and the inlet cover 12 is fixedly installed on the cooling tower body by multiple bolts. After prolonged use, foreign matter will accumulate between the pre-spreader 13 and the inlet cover 12, requiring cleaning. During cleaning, the inlet cover 12 must first be removed from the cooling tower body, and then the pre-spreader 13 must be removed from the inlet cover 12. This process requires a considerable amount of time for disassembly and reassembly.

[0003] In addition, after removing the baffle 16 on the side of the inlet cover 12, the pre-sprayer 13 is fixed on the inlet cover 12. Without removing the inlet cover 12, the pre-sprayer 13 will block the bottom nozzle 15 located below the inlet cover 12, making it impossible to repair or replace the bottom nozzle 15 in that area.

[0004] Therefore, the existing pre-seeder installation structure is inconvenient to use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pull-out pre-watering device installation structure, which can solve the problem of inconvenience in previous use.

[0006] To solve the above-mentioned technical problems, this utility model discloses a pull-out pre-water distributor installation structure, including a guide rail, a pre-water distributor, a cooling tower with a water inlet, and a cover plate assembly for covering the water inlet; the guide rail is fixedly installed inside the water inlet, and the inner side of the guide rail is provided with a pair of spaced-apart support parts, which are arranged along the length of the guide rail so that a sliding groove is formed between the pairs of support parts; the top of the pre-water distributor extends outward with a pair of spaced-apart retaining parts; in the assembled state, the pre-water distributor is placed in the sliding groove, and the support parts abut against the corresponding retaining parts so that the pre-water distributor is retained in the sliding groove, and the pre-water distributor can slide along the sliding groove.

[0007] The guide rail includes a support part arranged along the width direction of the inlet, a first guide part vertically fixed to one end of the support part, and a second guide part vertically fixed to the other end of the support part.

[0008] Among them, a pair of supporting parts are formed on the bottom inner side of the first guide part and the bottom inner side of the second guide part.

[0009] The ratio of the length of the first guide section, the length of the second guide section, the length of the inlet, and the length of the pre-water distributor is 2:2:3:1.

[0010] The top of the support, the top of the first guide, and the top of the second guide are all bent outward to form an installation part for fixing to the water inlet.

[0011] Each mounting section has at least one first mounting hole.

[0012] This also includes a water-spraying base plate fixedly installed at the bottom of the water inlet, on which multiple water-spraying nozzles are fixedly installed at intervals.

[0013] The bottom surface of the pre-watering device has multiple through holes arranged at intervals.

[0014] The pre-water dispenser has multiple spaced water holes on its outer periphery.

[0015] It also includes a support component, which is fixedly installed on the bottom surface of the pre-watering device.

[0016] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0017] (1) By sliding the guide rail and the pre-watering device's holding part together, the pre-watering device can be directly pulled out from the sliding groove by simply opening the cover plate assembly during disassembly. This replaces the previous installation structure where the pre-watering device was fixed on the cover plate assembly, simplifies the disassembly process, shortens the disassembly time, solves the previous problem of inconvenience, and realizes the quick installation and disassembly of the pre-watering device.

[0018] (2) The operation of the pre-sprayer is completely independent of the main structure of the cooling tower. During the maintenance of a single module, the other modules can still operate normally, making it easier to maintain the nozzles on the water distribution tray. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or server that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or servers.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This utility model discloses a specific embodiment of a pull-out pre-seeder installation structure. Please see [link / reference]. Figure 2 and Figure 3As shown, the installation structure includes components such as guide rail 4, pre-water distributor 5, cooling tower body with water inlet 2, cover plate assembly 3, and water distribution base plate 71. It should be noted that the cover plate assembly 3 is mainly used to cover the water inlet 2 of the cooling tower body. Specifically, the cover plate assembly 3 includes one water inlet cover 31 and four baffles 32, of which two baffles 32 are located on the left side of the water inlet cover 31, and the other two baffles 32 are located on the right side of the water inlet cover 31. Each baffle 32 and the water inlet cover 31 are fixed to the water inlet 2 with screws.

[0027] In this embodiment, the guide rail 4 is fixedly installed inside the cooling tower inlet 2 by bolts. Specifically, the guide rail 4 consists of a support part 41, a first guide part 42 vertically fixed to one end of the support part 41, and a second guide part 43 vertically fixed to the other end of the support part 41. The top of the support part 41, the top of the first guide part 42, and the top of the second guide part 43 are all bent outward to form a mounting part 44 for fixing to the inlet 2. Each mounting part 44 has at least one first mounting hole. The external screw passes through the first mounting hole and is threaded to the hole in the cooling tower body, thereby realizing the fixed installation of the guide rail 4 inside the cooling tower body inlet 2.

[0028] As an improvement, a pair of support portions 45 are formed on the inner bottom sides of the first guide portion 42 and the second guide portion 43, respectively. This can be understood as the bottom of the first guide portion 42 and the bottom of the second guide portion 43 both bending inwards to form the support portion 45. The main function of the support portion 45 is to support the pre-water dispenser 5. The two support portions 45 are spaced apart and extend along the length of the guide rail 4, so that a sliding groove is formed between the two support portions 45.

[0029] In this embodiment, the top of the pre-spreader 5 extends outward with a pair of retaining parts 51. During assembly, the entire pre-spreader 5 is placed into the sliding groove of the guide rail 4, so that the supporting part 45 abuts against the corresponding retaining part 51, realizing the slidable retaining of the pre-spreader 5 in the sliding groove. The bottom surface of the pre-spreader 5 has multiple through holes 52 arranged at intervals. The through holes 52 are mainly used to form axial alignment with the water-spreading nozzle 72 to facilitate subsequent water-spreading work. In addition, the outer peripheral side of the pre-spreader 5 has multiple water-spreading holes 53 to optimize water flow distribution. To enhance stability, a support member 6 is also fixedly installed on the bottom surface of the pre-spreader 5. The bottom of the support member 6 mainly contacts the bottom of the water-spreading nozzle, which plays the role of supporting the pre-spreader 5 and preventing the center of the bottom surface of the pre-spreader 5 from sinking. In addition, the outer peripheral side of the support member 6 also has multiple water-spreading holes 53 arranged at intervals to optimize water flow distribution.

[0030] As another improvement, the ratio of the length of the first guide part 42, the length of the second guide part 43, the length of the inlet 2, and the length of the pre-water dispenser 5 is 2:2:3:1. With this structural design, the guide rail 4 can be fixedly installed on the left side inside the inlet 2, so that a gap is formed between the end of the guide rail 4 and the right side inside the inlet 2. The pre-water dispenser 5 can slide along the guide rail 4. When the pre-water dispenser 5 slides to the end of the guide rail 4, it can be driven to slide out of the guide rail 4 and fall into the gap. This allows the pre-water dispenser 5 to detach from the guide rail 4, making it easier to remove the dispenser.

[0031] In this embodiment, the water-spraying base plate 71 is fixed to the bottom of the water inlet 2, and multiple water-spraying nozzles 72 arranged at intervals are installed on it.

[0032] The operation flow of the installation mechanism in this embodiment is as follows: After disassembling the cover plate assembly 3, the pre-spreader 5 can be directly removed from the guide rail 4 through the cooperation of the holding part 51 and the sliding groove, without disassembling the bolts or pipes. When maintenance is required on the water-spreading nozzle 72, after disassembling the cover plate assembly 3, the pre-spreader 5 can be driven to slide along the guide rail 4, thereby preventing the pre-spreader 5 from blocking the water-spreading nozzle 72 that needs maintenance.

[0033] Finally, it should be noted that the pull-out pre-watering device installation structure disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
