[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, a steel structure cooling tower is provided, which is suitable for thermal power generation, comprising: a tower body 1, the tower body 1 including at least two bidirectional triangular trusses 101; a support platform 2, located at the bottom of the tower body 1, the support platform 2 being suitable for installing radiators; the tower body 1 and the support platform 2 are prefabricated steel structures.

[0030] In this application, the prefabricated steel structure is manufactured in the factory. By replacing traditional concrete construction with steel structure, the efficiency of on-site construction can be greatly improved and the cost of enterprises can be reduced, thereby overcoming the disadvantages of traditional concrete construction, such as high requirements for conditions and long construction period.

[0031] In one embodiment, such as Figure 1 , Figure 2 , Figure 3As shown, each bidirectional triangular truss 101 includes a transverse ring 1012 and a first longitudinal leg 1011. It should be noted that each bidirectional triangular truss 101 includes a first longitudinal leg 1011 and a transverse ring 1012. The fixed connection between the transverse ring 1012 and the first longitudinal leg 1011 enhances the structural strength of the bidirectional triangular truss 101. Figure 1 , Figure 2 As shown, the first longitudinal support leg 1011 is arranged in an arc shape along its own length direction.

[0032] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the transverse ring 1012 and the first longitudinal support leg 1011 are integrally formed. The heights of the transverse rings 1012 of adjacent bidirectional triangular trusses 101 are different. The first longitudinal support leg 1011 and the transverse ring 1012 are fixedly connected by welding. The integrally formed transverse ring 1012 and the first longitudinal support leg 1011 facilitate prefabrication and welding, improving welding quality and efficiency, thereby achieving the expected welding quality and ensuring that the produced bidirectional triangular trusses 101 meet the corresponding strength standards. The different heights of the transverse rings 1012 of adjacent bidirectional triangular trusses 101 allow for connection with the first longitudinal support legs 1011 of other bidirectional triangular trusses 101 when forming a cooling tower. This also strengthens the overall structural strength of the cooling tower through the transverse rings 1012 of different heights.

[0033] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the two-way triangular truss 101 includes several transverse support rods 1014 and several diagonal support rods 1013. Adjacent transverse support rods 1014 are spaced apart, and adjacent diagonal support rods 1013 are also spaced apart. The transverse support rods 1014 and diagonal support rods 1013 are fixedly connected. The two-way triangular truss 101 is constructed through the connection between the transverse support rods 1014 and diagonal support rods 1013. The spaced-apart transverse support rods 1014 and diagonal support rods 1013 reduce the overall weight of the two-way triangular truss 101 while maintaining its overall structural strength.

[0034] In one embodiment, such as Figure 3 , Figure 4 As shown, the oblique support rod 1013 and the transverse support rod 1014 form a triangular structure, the transverse ring 1012 is arranged in a double-layered triangle along the height direction, and the first longitudinal support leg 1011 is arranged in a bidirectional triangle along the length direction. Figure 4As shown, the transverse ring 1012 is arranged in a double-layered triangular configuration along its height direction. That is, the transverse ring 1012 is arranged in a ring shape along its circumferential direction, forming a single-layered ring structure from several triangles. The transverse ring 1012 includes a double-layered ring structure, and the two layers of ring structures share the same horizontal support rod. It should be noted that the central axis of the transverse ring 1012 coincides with the central axis of the cooling tower.

[0035] In this embodiment, as Figure 4 As shown, the first longitudinal support leg 1011 is arranged in a bidirectional triangular configuration along its length. That is, at least two triangles are provided at each height along the length of the first longitudinal support leg 1011. The arrangement of the transverse ring 1012 and the first longitudinal support leg 1011 enhances the overall structural strength of the entire bidirectional triangular truss 101. The circumferential and longitudinal triangles form a bidirectional orthogonal truss structure, enabling the first longitudinal support leg 1011 and the transverse ring 1012 to work together to bear vertical loads and horizontal wind loads. It should be noted that the dimensions of the transverse ring 1012 and the first longitudinal support leg 1011 can be adjusted according to the shape and size of the tower.

[0036] In one embodiment, such as Figure 1 , Figure 2 As shown, the tower body 1 also includes a second longitudinal support leg 102. A second longitudinal support leg 102 is provided between adjacent first longitudinal support legs 1011, and the second longitudinal support leg 102 is fixedly connected to transverse rings 1012 at different heights. The second longitudinal support leg 102 strengthens the connection between the transverse rings 1012, improving the overall strength of the cooling tower. In fact, if the transverse rings 1012 are arranged too densely, or if the second longitudinal support leg 102 is not provided, the weight of the entire tower body 1 will increase, raising production costs for the company. Providing the second longitudinal support leg 102 reduces related costs while ensuring structural strength.

[0037] In this application, the tower body 1 is composed of four bidirectional triangular trusses 101 and four second longitudinal legs 102, namely, four first longitudinal legs 1011 and four transverse rings 1012. Second longitudinal legs 102 are provided between adjacent first longitudinal legs 1011. The second longitudinal legs 102 are fixedly connected to transverse rings 1012 of different heights to form the tower body 1.

[0038] It should be noted that the second longitudinal support leg 102 and the first longitudinal support leg 1011 have the same structure and dimensions, thus enhancing the overall strength of the cooling tower. However, the dimensions of the transverse ring 1012 must be designed according to the dimensions of the tower body on site, and the diameters of different transverse rings 1012 are not equal. Figure 1 , Figure 2 and Figure 3As shown, the top of the tower body 1 is provided with a horizontal ring 1012, and the top and bottom of the first longitudinal support leg 1011 and the second longitudinal support leg 102 are pointed to facilitate fixed connection.

[0039] In one embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the tower body 1 also includes a single-layer truss 103. Several accommodating spaces are formed between the first longitudinal support leg 1011, the second longitudinal support leg 102 and the transverse ring 1012. A single-layer truss 103 is located in one accommodating space. Each single-layer truss 103 is fixedly connected to the first longitudinal support leg 1011, the second longitudinal support leg 102 and the adjacent transverse ring 1012, respectively. That is, a single-layer truss 103 is arranged in a one-to-one correspondence with an accommodating space.

[0040] In this embodiment, as Figure 1 , Figure 2 As shown, a receiving space is enclosed by adjacent first longitudinal legs 1011 and second longitudinal legs 102, and two adjacent transverse rings 1012. A single-layer truss 103 is disposed within the receiving space. The single-layer truss 103 is fixedly connected to the first longitudinal legs 1011, the second longitudinal legs 102, and the two adjacent transverse rings 1012 by welding. The single-layer truss 103 serves as a connector and also provides protection as part of the tower body 1. The single-layer truss 103 has a curved surface. In addition, the single-layer truss 103 structural system is reliable, has a clear force transmission path, has a small number of overall members, and is simple to construct and install, reducing material costs and construction time.

[0041] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the tower body 1 also includes a triangular reinforcing truss 104. The first longitudinal support leg 1011, the second longitudinal support leg 102, and the transverse ring 1012 are fixedly provided with the triangular reinforcing truss 104 facing the central axis of the tower body 1. The triangular reinforcing truss 104 serves to strengthen the first longitudinal support leg 1011, the second longitudinal support leg 102, and the transverse ring 1012. That is, the inner circumferential surface of the tower body 1 is provided with the triangular reinforcing truss 104. It should be noted that the single-layer truss 103 is not fixedly connected to the triangular reinforcing truss 104.

[0042] In one embodiment, such as Figure 7As shown, the support platform 2 includes a set of triangular support frames 201 arranged along the axis of the tower body 1. The ends of the first longitudinal support leg 1011 and the second longitudinal support leg 102 are respectively fixedly connected to the triangular support frames 201, thereby fixing the tower body 1 to the triangular support frames 201. It should be noted that the first longitudinal support leg 1011 and the second longitudinal support leg 102 of the tower body 1 are fixedly connected to the triangular support frames 201 by welding.

[0043] In one embodiment, such as Figure 7 As shown, the support platform 2 also includes a longitudinal support rod 202. The support point 2011 of the triangular support frame 201 is fixedly connected to the longitudinal support rod 202, so as to fix it to the ground through the longitudinal support rod 202, and the support platform 2 supports the tower body 1. In this application, the common overlapping point of adjacent triangular support frames 201 is the support point 2011.

[0044] In this embodiment, as Figure 7 As shown, the support platform 2 is set at a predetermined position along the circumference of the tower body 1. The support platform 2 is used to install the radiator. The predetermined position is set according to the usage requirements of the steel structure cooling tower and the installation requirements of the radiator. For example, the predetermined position is 30m away from the ground surface. The support platform 2 includes a triangular support frame 201 and a longitudinal support rod 202.

[0045] In this embodiment, as Figure 7 As shown, the triangular support frame 201 also includes a support point 2011, and the intersection of two adjacent triangular support frames is the support point 2011. The support platform 2 includes a set of triangles arranged circumferentially along the tower body 1. Figure 7 As shown, the triangular support frame 201 consists of several repeated triangles connected to the support vertex 2012 around the tower body 1 at a set position.

[0046] In this embodiment, as Figure 7 As shown, one end of the longitudinal support rod 202 is connected to the support point 2011, and the other end is connected to a support apex 2012 located below the support point 2011; or, one end of the longitudinal support rod 202 is connected to the support point 2011, and the other end is connected to a support apex 2012 located on the ground. Figure 7 As shown, the longitudinal support rod 202 and the support point 2011 are provided with welded balls or welded columns.

[0047] The bidirectional triangular truss 101, the second longitudinal leg 102, the single-layer truss 103, and the support platform 2 of the cooling tower in this application are all prefabricated in the factory after the design is completed, and then transported to the construction site for assembly; or, the transverse ring 1012 and the first longitudinal leg 1011 of the bidirectional triangular truss 101 can be prefabricated in the factory and then assembled and fixed after being transported to the site.

[0048] The steel structure cooling tower provided by this utility model has the following advantages: (1) It overcomes the disadvantages of traditional concrete construction conditions being high and construction period being long. It adopts a two-way orthogonal large triangular truss steel structure cooling tower with high rigidity of members and overall structure, high overall strength, high material utilization rate, and good stability; (2) By setting a single-layer truss 103, not only can the protection capability of the cooling tower be enhanced, but the overall weight of the cooling tower can also be reduced; (3) It is made of the same material, and the design of the tower body 1 and the expansion platform can be completed by the same designer or the same type of designer, which makes it easier to communicate the plan, saves communication time, and makes it easier to provide information; (4) The entire structure of this application is prefabricated. The cost of steel structure is lower than that of concrete structure. Therefore, the steel structure cooling tower of this utility model also has the advantage of saving costs.
