[0063] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, 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 a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0064] As modern power stations increasingly rely on high-temperature and high-pressure generators, cooling towers are becoming increasingly important. Traditional cooling towers are concrete cooling towers, which are heavy and susceptible to earthquakes. Affected by winter construction, the construction period is long, the commissioning time is long, and the cost of concrete cooling towers is high. Compared with concrete cooling towers, steel cooling towers are light in weight, have less earthquake effects, and can be installed on-site after the rods are processed in the processing plant. The construction speed is fast, which has great advantages and has gradually begun to be promoted and used in various thermal power plants.

[0065] The existing straight cone steel structure tower adopts a conical section at the bottom and a cylindrical section at the top. This type of tower is easy to install, but the cooling effect is worse than that of a hyperbolic cooling tower. The existing hyperbolic double-layer steel structure tower adopts a double-layer truss unit, and the number of rods is several times that of a single-layer structure. The workload of installing components and nodes is very large, and the construction period is long.

[0066] The steel structure cooling tower is a spatial structure formed by splicing several rods and connection nodes. Due to the huge volume of the cooling tower, it requires tens of thousands of rods. The structure of the connection node and the connection node form of each rod will directly affect the construction speed and quality of the entire steel structure cooling tower. There is a bolt ball connection node in the prior art. Due to the long length of the bolt rod, when tightening the bolt rod in the air, there is a phenomenon of "false tightening" between each bolt rod and the bolt ball, which is difficult to ensure the reliability of the connection between the two, so that the steel structure cooling tower has serious safety hazards. There is also a welding ball node in the prior art, and each structural rod can be directly welded to the welding ball to complete the installation. However, due to the large number of structural rods, the welding amount is large, the installation process is slow, and the construction progress is affected; and the steel structure cooling tower is a spatial structure. When welding is performed at high altitude, the operation is extremely inconvenient, it is difficult to ensure the welding quality and the construction safety of the operator, and the welding reliability is poor, so that the steel structure cooling tower also has certain safety hazards. Therefore, how to provide a steel structure cooling tower that is easy to install and has a stable structure is still a technical problem that needs to be solved by technicians in this field.

[0067] Combine the following Figures 1 to 12 , describing an embodiment of the utility model.

[0068] like Figure 1 and Figure 3 As shown, according to an embodiment of the utility model, a cooling tower 100 is provided, the outer side surface of the cooling tower 100 is a hyperbolic surface, and a multi-layer annular grid structure is formed along the axial direction, the cooling tower 100 includes a plurality of assembly units 110, each assembly unit 110 includes a hub node 113, a transverse rod 111 and two oblique rods 112, the transverse rod 111 and the two oblique rods 112 are respectively plugged into the hub node 113 through corresponding ends, and the plurality of assembly units 110 are connected in sequence to form a grid structure, and the plurality of transverse rods 111 in each layer of the grid structure are connected through a plurality of hub nodes 113 to form an annular rod 1101, and each transverse rod 111 and the two oblique rods 112 form a triangular structure.

[0069] It can be understood that the triangular structure is an equilateral triangle or an isosceles triangle, which makes the tower structure of the cooling tower 100 simple, the force is clear, and the structure of the cooling tower 100 is more stable.

[0070] The cooling tower 100 is a steel structure cooling tower. Figure 4The cooling tower 100 is set up with straight generatrixes in two directions in the hyperbolic surface, wherein the oblique rods 112, the annular rods 1101 and the hub nodes 113 are connected to form a hyperbolic cooling tower of a space lattice steel structure, and the outer side of the cooling tower 100 is in the shape of a hyperbolic surface, which can bring better cooling effect. The bidirectional oblique rods 112 form a hyperbolic tower body, and each layer of intersection nodes is arranged along a ring, and the oblique rods 112 and the transverse rods 111 are connected, which ensures the stability of the circumferential force of the tower body.

[0071] like Figure 7 As shown, the oblique rods 112 are inclined, and the intersections between the oblique rods 112 are the layering points of the cooling tower structure. The annular rods 1101 connect the layering points of each layer. The oblique rods 112 and the annular rods 1101 together constitute a single-layer hyperbolic grid structure of a triangular grid.

[0072] The oblique rods 112, the transverse rods 111 and the hub nodes 113 are assembled into an assembly unit 110. When installing the cooling tower 100, the assembly unit 110 can be installed in advance, and then can be hoisted, such as Figure 2 As shown, the assembly unit 110 can be hoisted by the hoisting structure and assembled into each layer of the grid structure in sequence, thereby improving the assembly efficiency of the cooling tower 100. When assembling the assembly unit 110, the transverse rod 111 and the oblique rod 112 are connected to the hub node 113 by plugging, and the assembly accuracy is high.

[0073] Specifically, Figure 8 and Fig. 9 As shown, the hub node 113 has an axis, and a plurality of slots 1132 are arranged around the axis on the outer peripheral surface of the hub node 113 . The slots 1132 extend along the length direction of the hub node 113 to connect the oblique rods 112 and the transverse rods 111 .

[0074] The slots 1132 are arranged along the length direction of the hub node 113. Six slots 1132 can be arranged on the periphery of the hub node 113, wherein two slots 1132 are arranged opposite to each other and are used to connect two transverse rods 111, so that a plurality of transverse rods 111 can be connected to form a ring rod 1101 through the hub node 113. The other four slots 1132 are respectively connected to the oblique rods 112, and the two oblique rods 112 are located above the transverse rod 111, and the other two oblique rods 112 are located below the transverse rod 111. The four oblique rods 112 and one transverse rod 111 form two triangular structures.

[0075] Furthermore, if Fig.10As shown, the slot 1132 includes a first slot 11321 and a second slot 11322 . The first slot 11321 extends to the outer circumference of the hub node 113 . The second slot 11322 is connected to the first slot 11321 . The internal space of the second slot 11322 is larger than the internal space of the first slot 11321 .

[0076] It can be understood that the first notch 11321 is located outside the second notch 11322. The first notch 11321 and the second notch 11322 can be holes with notches. The cross-section of the first notch 11321 is in the shape of a rectangle, a rectangle or other shapes, which are not specifically limited here. The first notch 11321 is connected to the ends of the oblique rod 112 and the transverse rod 111, and the ends of the oblique rod 112 and the transverse rod 111 can be inserted into the first notch 11321 and matched with the first notch 11321.

[0077] The slot 1132 is divided into a first slot 11321 and a second slot 11322. Correspondingly, the ends of the transverse rod 111 and the oblique rod 112 can also be divided into two parts, a first connecting part 1102 and a second connecting part 1103, wherein the first connecting part 1102 is cooperatively connected with the first slot 11321, and the second connecting part 1103 is cooperatively connected with the second slot 11322.

[0078] More specifically, the first connection portion 1102 is a rectangular block structure, and the second connection portion 1103 is a cylindrical structure.

[0079] It can be understood that the internal space of the second slot 11322 is larger than the internal space of the first slot 11321, so that the second connecting portion 1103 will not be separated from the hub node 113 through the first slot 11321, thereby improving the firmness of the connection between the transverse rod 111, the oblique rod 112 and the hub node 113.

[0080] Each hub node 113 can be connected to six rods. The hub body 1131 is cylindrical, and six slots 1132 are opened at corresponding positions around the periphery. The internal space of the slots 1132 is larger than the external opening size, which can form a snap-fit ​​effect.

[0081] In another embodiment, if Figure 8 and Fig. 9 As shown, the slot 1132 extends to the opposite ends of the hub node 113 in the length direction of the hub node 113. The hub node 113 includes: a hub body 1131 and a locking member 114. The hub body 1131 is provided with a plurality of slots 1132. The locking member 114 is detachably connected to the hub body 1131 and is extruded and connected to the transverse rod 111 and the oblique rod 112 on the hub node 113.

[0082] It can be understood that the first notch 11321 and the second notch 11322 both extend to the two end surfaces of the hub node 113, so that the transverse rod 111 and the oblique rod 112 can be inserted into the slot 1132 from the end of the hub node 113, thereby improving the connection accuracy between the transverse rod 111 and the oblique rod 112 and the hub node 113. The transverse rod 111 and the oblique rod 112 are locked on the hub node 113 in a detachable connection manner by the locking member 114, thereby improving the firmness of the connection structure of the transverse rod 111 and the oblique rod 112.

[0083] In another embodiment, the hub body 1131 is provided with a connection hole along the length direction, and a plurality of slots 1132 are arranged around the connection hole, such as Fig. 9 As shown, the locking member 114 includes a connecting rod 1141, a first cover plate 1142 and a second cover plate 1143. The connecting rod 1141 passes through the connecting hole, the first cover plate 1142 is arranged at one end of the hub body 1131 and is detachably connected to the connecting rod 1141, and the second cover plate 1143 is arranged at the other end of the hub body 1131 and is detachably connected to the connecting rod 1141.

[0084] When the hub body 1131 is a cylindrical structure, the first cover plate 1142 and the second cover plate 1143 are circular cover plates.

[0085] It can be understood that the connecting rod 1141 can be a screw rod, and the central parts of the first cover plate 1142 and the second cover plate 1143 are perforated, and the hole diameter is consistent with the hole diameter of the connection hole with the hub body 1131.

[0086] The first cover plate 1142 and the second cover plate 1143 can form a limit for the oblique rod 112 and the transverse rod 111 connected to the slot 1132, so that the transverse rod 111 and the oblique rod 112 will not be pulled out of the hub node 113. Specifically, the connecting hole can be set at the center of the hub body 1131. When the hub body 1131 is a cylindrical structure, the connecting hole can be set at the axis of the hub body 1131. The connecting rod 1141 passes through the connecting hole and passes through the first cover plate 1142 and the second cover plate 1143 at both ends, and then the first cover plate 1142 and the second cover plate 1143 are respectively locked at the two ends of the hub body 1131 by locking nuts or nuts 1144.

[0087] By using the plug-in hub node 113 at the connection node of the cooling tower 100, during the installation process, it is only necessary to insert the rod into the slot 1132 of the hub node 113 and tighten the nut 1144 to fix it. There is no welding in the whole process, and the installation is convenient and quick.

[0088] In another embodiment, the annular rod 1101 is formed into a circular ring, such as Figure 5As shown, both ends of the transverse rod 111 have first wedge-shaped structures respectively, and the first wedge-shaped structures form first edge lines 1111 , and the first edge lines 1111 all point to the center of the annular rod 1101 .

[0089] It can be understood that, Figure 5 As shown, the end of the transverse rod 111 is set to a wedge-shaped structure, which makes it easier to insert the transverse rod 111 into the slot 1132, so as to improve the installation efficiency of the transverse rod 111. The edge of the first wedge-shaped structure forms a first edge line 1111, and the first edge line 1111 is inclined relative to the axis of the transverse rod 111. The first edge line 1111 points to the center of the annular rod 1101, so that multiple transverse rods 111 can be connected to the annular rod 1101 through the hub node 113.

[0090] In another embodiment, if Figure 6 As shown, both ends of the oblique rod 112 have a second wedge structure respectively, and the second wedge structure forms a second edge line 1121. The angle formed by the second edge line 1121 and the axis of the corresponding oblique rod 112 is consistent with the hyperbolic surface.

[0091] It can be understood that the end of the oblique rod 112 is set to a wedge-shaped structure, which makes it easier to insert the oblique rod 112 into the slot 1132, so as to improve the installation efficiency of the oblique rod 112. The edge of the second wedge-shaped structure forms a second edge line 1121, and the second edge line 1121 is inclined relative to the axis of the oblique rod 112, so that the oblique rods 112 intersect with the hub node 113 and form a hyperbolic structure.

[0092] Both ends of the rod are pressed into a wedge shape, the length of the wedge is the same as the length of the hub body 1131, the shape is consistent with the shape of the slot 1132, and the outer dimension of the wedge is 1mm to 2mm smaller than the slot 1132 of the hub body 1131, which facilitates the insertion of the rod into the slot 1132 of the hub body 1131.

[0093] During installation, first connect a cover plate to one end of the hub body 1131 through a screw and a nut 1144, then insert the rod into the groove from the other end of the hub body 1131, and after the rod is inserted, cover it with another cover plate and tighten it with a nut 1144 through the screw.

[0094] In another embodiment, if Fig.11 and Fig.12 As shown, the cooling tower 100 further includes a base 120 , and a plurality of hub nodes 113 are disposed on the top of the base 120 , each hub node 113 being used to connect two oblique rods 112 forming a triangular structure.

[0095] The base 120 can be arranged on the ground, for example, the base 120 can be arranged on the ground as an embedded part. A plurality of hub nodes 113 are arranged circumferentially on the top of the base 120, and two oblique rods 112 forming a triangular structure are connected by the hub nodes 113, so that the base 120 can provide a more stable support for the cooling tower 100, and provide the overall structural strength and firmness of the cooling tower 100.

[0096] The base 120 includes a concrete support 121 , and two spaced-apart support rods 122 are disposed on the top of the concrete support 121 . The two support rods 122 are respectively connected to the hub nodes 113 .

[0097] It can be understood that a plurality of concrete supports 121 are provided, each of which can be a rectangular structure, and an embedded steel plate 123 is provided on the top of the concrete support 121, and two support rods 122 can be welded on the embedded steel plate 123, so that the two support rods 122 form a herringbone structure or an eight-shaped structure, so as to provide a more stable support for the main structure of the cooling tower 100. It can be understood that the upper ends of the support rods 122 are respectively provided in a wedge-shaped structure, so as to improve the accuracy of insertion into the slot 1132 and improve the installation efficiency.

[0098] Two support rods 122 are connected under the first layer of grid at the bottom. The support rods 122 are short rods with a length of generally 300 mm to 500 mm. One end of the support rod 122 is pressed into a wedge shape identical to the end of a bidirectional oblique rod and inserted into a slot 1132 at the bottom of the hub node 113. The other end of the support rod 122 is not pressed but uses the original cross-section of the rod and is welded to the embedded steel plate 123 disposed on the top of the concrete support 121.

[0099] The present application also provides a construction method of a cooling tower, comprising the following steps:

[0100] Step S101: assembling any one of the cooling tower assembly units 110;

[0101] Step S102: connecting multiple assembly units 110 into a ring-shaped grid structure;

[0102] Step S103: installing a plurality of grid structures in sequence from bottom to top, and making the outer side surface of the cooling tower a hyperbolic surface.

[0103] The steps of connecting the multiple assembly units 110 into a ring-shaped grid structure specifically include the following steps:

[0104] Step S210: two oblique rods 112 are respectively installed at both ends of one of the transverse rods 111 of each layer of the grid structure, and a hub node 113 is installed at the intersection of the two oblique rods 112 to form a triangular structure;

[0105] Step S220: Connect the free end of the transverse rod 111 and the free end of one oblique rod 112 in the assembly unit 110 to the hub nodes 113 of the adjacent triangular structures respectively.

[0106] It can be understood that the support rods 122 around the bottom of the base 120 are inserted into the hub node 113, and then the support rods 122 are welded to the top embedded steel plate 123 of the concrete support 121, and then the first layer of the grid structure at the bottom is installed. The first layer of grid is close to the ground and is easy to install. The rods can be installed step by step in a clockwise or counterclockwise direction. When the first layer of triangular grids are closed, a stable system is formed at the bottom, and the second layer is installed. First, a herringbone bidirectional oblique rod is installed on a ring rod 1101 to form a triangular stable structure, and then each assembly unit 110 is hoisted and gradually installed until it is closed. The installation from the third layer to the top layer is consistent with the second layer.

[0107] Through the above installation steps, the installation of the cooling tower 100 is made more efficient and convenient, the installation efficiency of the cooling tower 100 is greatly improved, the construction period of the cooling tower 100 is shortened, and the construction cost is saved.

[0108] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods.
