Technical Field

[0001] The invention relates to the technical field of cooling towers, and in particular to a steel structure cooling tower enclosure structure. Background Art

[0002] Cooling tower is one of the main structures of thermal power plant, among which natural ventilation indirect cooling tower is widely used in my country, especially in the water-scarce northwest region.

[0003] With the development of space steel structure technology, steel cooling towers are increasingly used. Compared with concrete towers, steel tower structures have the advantages of light weight, outstanding seismic performance, and fast construction speed. The enclosure structure of steel cooling towers can adopt a lightweight roof system, which is easier to install and construct, and further optimizes the steel tower structure. The enclosure panels of the lightweight roof system generally use corrugated aluminum plates or corrugated steel plates, but because steel structure towers are usually in the form of spatial curved surfaces and have a large height range, the design and installation of the enclosure panels are more difficult. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the enclosure structure of the steel structure cooling tower in the prior art that the design and installation are difficult, thereby providing a steel structure cooling tower enclosure structure.

[0005] The present invention provides a steel structure cooling tower enclosure structure, which is suitable for being arranged outside a cooling tower body, and comprises:

[0006] A plurality of purlin structures are distributed in a ring shape along the outer side of the cooling tower body and are extended in the height direction;

[0007] A plurality of enclosure units are arranged at intervals on the outside of the cooling tower body in a circumferential direction and are fixedly assembled and connected layer by layer along the height direction, including a plurality of enclosure panels fixedly connected along the circumferential direction, and the enclosure panels are fixedly connected to two adjacent purlin structures;

[0008] The buckle groove structure is arranged between the enclosure units adjacent to each other in the circumferential direction and is fixedly connected to the enclosure units.

[0009] The buckle groove structure is arranged linearly along the height direction.

[0010] The buckle groove structure includes: an outer edge portion, which is arranged on the outer side of the enclosure panel and is fixedly connected to the enclosure panel.

[0011] The inner concave portion is protruded toward the axis of the cooling tower body, is fixedly connected to two adjacent outer edge portions, and is formed with a bending structure, and the bending structure is adjacent to the circumferential end of the enclosure panel.

[0012] The steel structure cooling tower enclosure structure also includes a plurality of receiving structures. The buckle groove structure is correspondingly arranged between two adjacent purlin structures. The receiving structure is fixed to the two adjacent purlin structures and the inner recess, and is suitable for supporting the inner recess.

[0013] A buffer structure is also provided between the outer edge portion and the enclosure panel.

[0014] A folding edge structure is also arranged on the outside of the outer edge portion, and the folding edge structure is arranged adjacent to the circumferential end of the outer edge portion and abuts against the enclosure panel.

[0015] The enclosure panel is a corrugated metal plate, which is evenly distributed along the outer side of the purlin structure. A plurality of wave peak structures protruding away from the purlin structure are arranged on the enclosure panel. The plurality of wave peak structures are arranged in a ring shape around the cooling tower body along the length direction.

[0016] A plurality of groove structures arranged at intervals are arranged on one side of the buffer structure facing the enclosure panel, and the groove structures are suitable for accommodating the wave crest structure.

[0017] The wave peak structures on adjacent enclosure panels are at least partially stacked and fixedly connected.

[0018] A sealing and fixing structure is arranged between adjacent stacked wave crest structures.

[0019] The sealing and fixing structure is arranged on two side surfaces of the buffer structure facing the enclosure panel and the outer edge portion respectively.

[0020] A plurality of the purlin structures are arranged in a hyperbolic tower shape.

[0021] The technical solution of the present invention has the following advantages:

[0022] 1. The present invention provides a steel structure cooling tower enclosure structure, which is suitable for being arranged on the outside of a cooling tower body, and comprises: a plurality of purlin structures, which are distributed in an annular shape along the outside of the cooling tower body and are extended in the height direction; a plurality of enclosure units, which are arranged at intervals in an annular direction on the outside of the cooling tower body and are fixedly assembled and connected layer by layer in the height direction, and comprise a plurality of enclosure panels fixedly connected in the circumferential direction, wherein the enclosure panels are fixedly connected to two adjacent purlin structures; and a buckle groove structure, which is arranged between the enclosure units adjacently arranged in the circumferential direction and is fixedly connected to the enclosure units.

[0023] There are different tower types for steel structure cooling towers, such as hyperbolic, straight, or straight-cone composite types, etc. Depending on the tower type, the outer diameter of the cooling tower body will change to varying degrees along the height direction, making the outer side of the cooling tower body a spatial curved surface with a constantly changing curvature, which increases the difficulty of installing the enclosure structure arranged on the outside of the cooling tower body, and requires the installation spacing and structural dimensions of each enclosure unit or enclosure panel on the enclosure structure to change according to the spatial curved surface, increasing the processing and installation errors of the enclosure panels.

[0024] By setting a buckle groove structure between each enclosure unit arranged along the circumferential direction, the processing error and installation error of the enclosure panel caused by the installation between each enclosure unit can be absorbed by adjusting the size of the buckle groove structure. On the one hand, the enclosure structure can adapt to a variety of tower structures, and on the other hand, the processing and construction difficulty of the steel structure cooling tower is reduced, thereby shortening the construction period of the project.

[0025] 2. The steel structure cooling tower enclosure structure provided by the present invention also includes a plurality of supporting structures, wherein the buckle groove structure is correspondingly arranged between two adjacent purlin structures, and the supporting structure is fixed to the two adjacent purlin structures and the inner recess, and is suitable for supporting the inner recess.

[0026] By providing a receiving structure, the inner recessed portion can be effectively supported along the circumferential direction of the cooling tower body, thereby improving the stability of the buckle groove structure and enabling it to effectively bear the windward load in the radial direction of the cooling tower.

[0027] 3. The steel structure cooling tower enclosure structure provided by the present invention further comprises a buffer structure between the outer edge portion and the enclosure panel.

[0028] By providing a buffer structure, the friction or impact between the outer edge and the enclosure panel can be effectively reduced, and the buckle groove structure can be prevented from being squeezed or rubbed by external forces such as wind loads, causing pitting and other damage to the enclosure panel.

[0029] 4. The steel structure cooling tower enclosure structure provided by the present invention, the enclosure panel is a corrugated metal plate, evenly distributed along the outer side of the purlin structure, and is provided with a plurality of peak structures protruding away from the purlin structure, and the plurality of peak structures are arranged in a ring shape around the cooling tower body along the length direction.

[0030] By arranging the wave crest structure in a circular shape along the length direction around the cooling tower body, this arrangement makes it easy for the wave crest structure on the enclosure panel to overlap with the wave crest structure on another enclosure panel in the vertical direction, thereby reducing the difficulty of assembling the enclosure unit along the vertical height direction, improving the assembly efficiency, and at the same time reducing the difficulty of processing the enclosure panel and construction.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] like Figure 1 - Figure 7 This embodiment provides a steel structure cooling tower enclosure structure, which is cylindrical and can be arranged outside the cooling tower body. In this embodiment, the cooling tower body is arranged in a hyperbolic tower shape. As a convertible implementation, it can also be a straight cylinder, a straight cone, etc. The enclosure structure includes a purlin structure 1, an enclosure unit and a buckle groove structure 3. In this embodiment, the outside refers to the direction away from the axis of the cooling tower body, and the inside refers to the direction toward the axis of the cooling tower body.

[0046] A plurality of purlin structures 1 are arranged outside the cooling tower body and are distributed in a ring shape along the circumference of the cooling tower body. The specific shape of the purlin is set according to the tower type of the cooling tower. In this embodiment, a plurality of purlin structures 1 are arranged in an arc shape extending along the height direction and form a hyperbolic tower barrel structure. As a convertible embodiment, when the cooling tower body tower type is a straight cylinder type or a straight cylinder tapered type, the purlin structure 1 can also be arranged in a straight rod shape or a bent rod shape.

[0047] The enclosure unit is in the shape of a long plate, and several enclosure units are arranged in a ring shape outside the cooling tower body. Adjacent enclosure units are arranged at intervals, and the enclosure units are fixedly assembled and connected layer by layer along the height direction. The enclosure unit includes a plurality of enclosure panels 2 that are fixedly connected along the circumferential direction of the cooling tower body. The specific shape and specification of the enclosure panel 2 are not too restricted, and it is sufficient to be fixedly connected with two adjacent purlin structures 1. In this embodiment, the enclosure panel 2 is in the shape of a rectangular sheet and is uniformly arranged in size.

[0048] The buckle groove structure 3 is arranged between the enclosure units arranged adjacently along the circumferential direction of the cooling tower body to connect and fix the adjacent enclosure units. In this embodiment, the buckle groove structure 3 can be made of a material such as a steel plate through a simple bending process, and the specification and size can be selected according to the enclosure unit spacing.

[0049] There are different tower types for steel structure cooling towers, such as hyperbolic, straight cylindrical, or straight cone composite types, etc. Depending on the tower type, the outer diameter of the cooling tower body will change to varying degrees along the height direction, making the outer side of the cooling tower body a spatial curved surface with a constantly changing curvature, which increases the difficulty of installing the enclosure structure arranged on the outside of the cooling tower body, and requires the installation spacing and structural dimensions of each enclosure unit or enclosure panel 2 on the enclosure structure to change according to the spatial curved surface, thereby increasing the processing and installation errors of the enclosure panel 2.

[0050] By setting a buckle groove structure 3 between each enclosure unit arranged along the circumferential direction, the processing error and installation error of the enclosure panel 2 caused by the installation between each enclosure unit can be absorbed by adjusting the size of the buckle groove structure 3. On the one hand, the enclosure structure can adapt to a variety of tower structures. On the other hand, the processing and construction difficulty of the steel structure cooling tower is reduced, and the construction period of the project is shortened.

[0051] In this embodiment, a plurality of buckle groove structures 3 are arranged linearly along the height direction, and each buckle groove structure 3 is respectively arranged correspondingly to the enclosure panels 2 on two adjacent enclosure units at the same height, and is fixedly connected thereto. In this way, when the buckle groove structures 3 are arranged linearly along the height direction, the enclosure panels 2 in the enclosure units can be arranged correspondingly along the height direction, which is convenient for the fixed installation and arrangement of the enclosure panels 2 along the height direction, and can also be convenient for displaying the spacing between the enclosure units at different heights, thereby facilitating the selection of the specifications of the buckle groove structures 3.

[0052] As a convertible implementation, the buckle groove structure 3 is in the shape of a long groove, and a single buckle groove structure 3 is arranged correspondingly to and fixedly connected to the enclosure panels 2 on multiple pairs of adjacent enclosure units at different heights. As another convertible implementation, the buckle groove structure 3 can be arranged nonlinearly along the height direction.

[0053] In this embodiment, the buckle groove structure 3 includes two outer edge portions and an inner concave portion 32 .

[0054] The two outer edges are arranged on both sides of the inner concave portion 32, are flat, and are arranged on the outside of the enclosure panel 2, and are fixedly connected to the enclosure panel 2. In this embodiment, the connection is fixed by rivets, and as a convertible implementation, it can also be screwed or welded.

[0055] The inner concave portion 32 is a square through groove, which is protruded toward the axis of the cooling tower body and is fixedly connected to two adjacent outer edges, and a bending structure 321 is formed at the connection position, which is adjacent to the end position of the enclosure panel 2 extending in the circumferential direction of the cooling tower body. The specific bending degree of the bending structure 321 is not limited, and it is a right angle in this embodiment.

[0056] The enclosure structure also includes a plurality of receiving structures 4. The buckle groove structures 3 are correspondingly arranged between two adjacent purlin structures 1. Each buckle groove structure 3 is provided with at least one receiving structure 4. The receiving structure 4 is fixed to the two adjacent purlin structures 1 and the inner recess 32, and is suitable for supporting the inner recess 32. By providing the receiving structure 4, the inner recess 32 can be effectively supported along the circumferential direction of the cooling tower body, thereby improving the stability of the buckle groove structure 3, so that it can effectively bear the windward load in the radial direction of the cooling tower.

[0057] In this embodiment, the receiving structure 4 is a receiving rod, which is perpendicular to and fixedly connected to two adjacent purlin structures 1. As a convertible implementation, the receiving structure 4 can also be a receiving plate or a receiving frame, etc. As a convertible implementation, the buckle groove structure 3 can be correspondingly arranged between two non-adjacent purlin structures 1.

[0058] In this embodiment, the enclosure panel 2 is a corrugated metal plate, which can be a steel plate or an aluminum plate, and is evenly distributed along the outer side of the purlin structure 1. A plurality of wave peak structures 21 that are relatively protruding away from the purlin structure 1 are arranged thereon. The wave peak structures 21 are evenly spaced on the panel in the shape of square strips, and a plurality of wave peak structures 21 are arranged in a ring shape along the length direction around the cooling tower body.

[0059] By arranging the peak structure 21 in a circular shape along the length direction around the cooling tower body, this arrangement makes it easy for the peak structure 21 on the protective panel 2 to overlap with the peak structure 21 on another protective panel 2 in the vertical direction, thereby reducing the difficulty of assembling the protective unit along the vertical height direction, improving the assembly efficiency, and at the same time reducing the difficulty of processing the protective panel 2 and construction.

[0060] The wave peak structures 21 on the adjacent enclosure panels 2 in the height direction are partially stacked and fixedly connected by setting a sealing fixing structure 7. In this embodiment, the connection method is adhesive fixing, and the sealing fixing structure 7 is a butyl double-sided tape. As a convertible embodiment, the adjacent enclosure panels 2 in the height direction can also be fixed by welding or screws.

[0061] Adjacent enclosure panels 2 in the same enclosure unit at the same height are partially stacked and fixedly connected by a sealing and fixing structure 7. In the present embodiment, the sealing and fixing structure 7 is a neutral silicone adhesive, which fixes the adjacent enclosure panels 2 by bonding. As a convertible implementation, adjacent enclosure panels 2 in the same enclosure unit can also be fixed by butyl double-sided tape, welding or screws.

[0062] In this embodiment, in order to cope with the change in the outer diameter of the cooling tower body at different heights, the number of enclosure panels 2 in the enclosure units arranged at different heights along the height direction may be different.

[0063] A buffer structure 5 is also provided between the outer edge 31 of the buckle groove structure 3 and the enclosure panel 2. The buffer structure 5 can effectively reduce the friction or impact between the outer edge 31 and the enclosure panel 2, and can prevent the buckle groove structure 3 from being squeezed or rubbed by external forces such as wind loads, causing pitting and other damage to the enclosure panel 2. In this embodiment, the buffer structure 5 is a molded foam plug with a built-in polyurethane soft foam material. As a convertible embodiment, the buffer structure 5 can also be a structure such as a rubber pad.

[0064] In this embodiment, the side of the buffer structure 5 facing the enclosure panel 2 is provided with a plurality of groove structures arranged at intervals, and the groove structures can accommodate the wave crest structures 21. This arrangement allows the buffer structure 5 to fit the shape of the enclosure panel 2, while improving the buffering effect, it also increases the stability of the installation.

[0065] The buffer structure 5 is provided with sealing and fixing structures 7 on two sides facing the enclosure panel 2 and the outer edge portion 31. In this embodiment, the sealing and fixing structure 7 is also a butyl double-sided tape. As a changeable embodiment, the buffer structure 5 may also not be provided.

[0066] In addition, a folding structure 6 is also provided on the outer side of the outer edge 31, and the folding structure 6 is fixed to the outer edge by rivets, and the folding edge at one end wraps the end of the outer edge extending in the circumferential direction of the cooling tower, and the folding edge abuts against the enclosure panel 2. In this way, the outer edge is prevented from receiving external force impact from the circumferential direction of the cooling tower, and the stability of the installation of the buckle groove structure 3 and the enclosure unit and the service life of the enclosure structure are improved.

[0067] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
