[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments 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.

[0025] The embodiment of the present application provides a composite closed cooling tower, which solves the problem that the top fan of the existing composite closed cooling tower is prone to malfunction and requires maintenance. Traditional fan fixing is generally directly fixed by multi-point screws, which makes fan maintenance inconvenient. Due to the high humidity at the top, the screws are prone to rust and are difficult to disassemble and assemble after rusting.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The utility model embodiment discloses a composite closed cooling tower. Figure 1-5 As shown, it comprises a cooling tower body 1, the top of the cooling tower body 1 is fixedly connected with a fan fixing seat 2, and the inner part of the fan fixing seat 2 is movably connected with a filter screen 4 and a fan body 3;

[0028] A cover plate 5 is disposed on the top of the fan body 3 , a slot 201 is formed on the fan fixing seat 2 , and a clamping block 501 is disposed on the bottom of the cover plate 5 . The clamping block 501 is movably clamped in the slot 201 .

[0029] Furthermore, the fan fixing seat 2 is provided with a locking mechanism corresponding to the block 501, and the locking mechanism includes a locking seat 6 fixedly connected to the fan fixing seat 2, and elastically retractable wedge blocks 602 are provided on both sides of the locking seat 6;

[0030] A locking groove 502 is provided on the block 501, and the wedge block 602 is movably engaged in the locking groove 502. The overall structure of the locking mechanism is simple and the operation is stable. The elastically retractable wedge block 602 is engaged to achieve the locking groove 502 of the block 501 to clamp and limit the position, thereby ensuring that the cover plate 5 and the fan body 3 are easily installed as a whole.

[0031] Furthermore, the locking seat 6 is internally slidably connected with a slider 601, and the wedge block 602 is fixedly connected to the slider 601. The slider 601 is provided to limit the wedge block 602 and ensure that the force on the wedge block 602 is stable.

[0032] Furthermore, a spring 603 is fixedly connected between the two sets of sliders 601. The spring 603 applies elastic force to the sliders 601 and the wedge block 602 as a whole, so that the wedge block 602 is not easy to loosen when inserted into the locking groove 502, thereby ensuring a good installation and fixing effect on the fan body 3.

[0033] It is particularly disclosed that a push handle 604 is provided on the slider 601, and a slot is provided on the locking seat 6. The push handle 604 is slidably connected in the slot. The push handle 604 is convenient for moving the slider 601 and the wedge block 602, thereby facilitating unlocking or locking the fan body 3.

[0034] The composite closed cooling tower can conveniently realize quick installation and fixation of the fan body 3 by means of a snap-on connection. The snap-on components are not easy to rust. Even if they are rusted, the fan body 3 can be conveniently disassembled and maintained, thereby realizing convenient inspection and maintenance of the fan body 3. At the same time, the filter screen 4 at the bottom of the fan body 3 can be conveniently disassembled and maintained, thereby ensuring that the top components of the composite closed cooling tower have a long service life and are easy for the staff to maintain, making the staff save time and effort in operation.

[0035] When installing and fixing the fan body 3 and the filter screen 4, the filter screen 4 is first clamped inside the fan fixing seat 2, and then the push handle 604 is pulled, so that the push handle 604 drives the slider 601 and the wedge block 602 to move as a whole and squeeze the spring 603. At this time, the fan body 3 is clamped inside the fan fixing seat 2, and the fan body 3 drives the cover plate 5 to clamp with the top of the fan fixing seat 2, and the cover plate 5 drives the clamping block 501 to clamp in the clamping groove 201. At this time, the push handle 604 is released, and the spring 603 stretches and pushes the slider 601 and the wedge block 602 to move, so that the wedge block 602 is inserted into the locking groove 502, thereby realizing the installation and fixation of the cover plate 5, the fan body 3 and the filter screen 4;

[0036] When the cover plate 5, the fan body 3 and the filter screen 4 need to be disassembled, the above-mentioned installation and fixing process can be reversed.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
