Description

Technical Field

[0001] The present application relates to the technical field of cooling towers, and particularly to a fixing mechanism, a packing module and a cooling tower. Background Art

[0002] In the field of industrial technology, cooling towers are often used to cool down high-temperature circulating cooling water so that the cooled circulating cooling water can be recycled again.

[0003] During the operation of the cooling tower, the packing module inside the cooling tower is the main performance component responsible for the heat exchange of the entire water system. The high-temperature circulating cooling water is evenly sprinkled on the packing module through a water distribution tray. The fan assembly at the top of the cooling tower keeps working, enabling the cold air to exchange heat with the high-temperature circulating cooling water in the packing module to achieve the cooling of the circulating cooling water, and then discharging the heated and humid air after heat exchange from the top of the cooling tower through the fan assembly. The cooled circulating cooling water drops into the water collecting tank below the packing module and is transported to the equipment to be cooled for recycling.

[0004] Since the packing module in the cooling tower is composed of many packing sheets assembled together, and the packing sheets have a certain flexibility. The traditional installation method is to apply glue between the packing sheets for pasting to connect them into an integral body that is not easily deformed, which is beneficial to the overall installation of the packing module. Pasting with glue can also prevent the gap between the packing sheets from being too large, resulting in a poor heat exchange effect. However, since the glue used for pasting is a chemical substance, it may cause corrosion and damage to the packing over time, and the glue mixed with the circulating water may also cause corrosion and damage to the surface of the metal parts in the water collecting tank or the equipment to be cooled.

[0005] In the prior art, in order to avoid the corrosion and damage to the packing or metal parts caused by the glue pasting method, the method of suspending the packing sheets with brackets is changed for installation. However, each specification of packing sheet needs to be provided with a corresponding specification of bracket, and the size of the bracket cannot be adjusted according to the size of the packing sheet, resulting in poor versatility of the packing sheet fixing structure in the prior art.

[0055] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0056] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0057] For ease of description, spatial relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation in addition to the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or motion state change, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "over other elements or features". Therefore, the exemplary term "below" can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0058] In order to solve the technical problem of poor versatility of the packing fixing structure in the prior art, the present application provides a fixing mechanism, a packing module, and a cooling tower, which can realize the adjustment of the installation space of the object to be fixed (such as the sheet packing 5, etc.), so as to adapt to the fixed installation of objects to be fixed with different sizes, and can improve the versatility of the fixing mechanism.

[0059] Please refer to Figures 1 to 12 , in the first aspect of the embodiment of the present application, a fixing mechanism is provided, which includes a through-rod assembly 1, a connection assembly 2, a telescopic assembly 3, and a frame assembly 4, as Figure 1 shown.

[0060] Among them, the through-rod assembly 1 is used to pass through the object to be fixed to realize the positioning of the object to be fixed in the fixing mechanism. Two connection assemblies 2 are respectively connected to both ends of the through-rod assembly 1 to limit both ends of the object to be fixed and prevent the fixed object to be fixed from slipping out of both ends of the through-rod assembly 1. A plurality of telescopic assemblies 3 are provided circumferentially on each connection assembly 2, and the limiting range of the connection assemblies 2 at both ends of the through-rod assembly 1 can be adjusted by the telescopic movement of the telescopic assemblies 3, and the contact range between the fixing mechanism and both end faces of the object to be fixed can be adjusted. The frame assembly 4 is connected to a plurality of telescopic assemblies 3 at both ends of the through-rod assembly 1 to form an installation space with adjustable size. When the telescopic assembly 3 expands and contracts, the frame assembly 4 moves along with the expansion and contraction of the telescopic assembly 3, so as to realize the adjustment of the size and shape of the installation space, and can realize the matching and fitting of the size and shape with the object to be fixed, ensuring that the object to be fixed will not shift inside the fixing mechanism, as Figure 11 shown, which can improve the versatility of the fixing mechanism.

[0061] It should be noted that the installation space refers to the space formed by enclosing multiple telescopic components 3 and the frame component 4. The rod-passing component 1 is located inside this installation space, and the object to be fixed is passed through the rod-passing component 1. The object to be fixed inside the installation space can be pre-positioned through the rod-passing component 1. Please refer to Figure 1 and Figure 6 , Figure 6 The dashed arrows in represent the telescopic directions of the corresponding telescopic components 3. Since multiple telescopic components 3 are arranged in sequence along the circumferential direction of the connecting component 2, when the telescopic direction of the telescopic component 3 is the vertical direction, the height dimension of the installation space can be adjusted; when the telescopic direction of the telescopic component 3 is the horizontal direction, the width dimension of the installation space can be adjusted; when the telescopic direction of the telescopic component 3 is the inclined direction, the height dimension and the width dimension of the installation space can be adjusted synchronously. The frame component 4 moves along with the telescopic component 3, and the size and shape of the installation space can be adjusted.

[0062] In some preferred embodiments of the present application, four telescopic components 3 are provided on each connecting component 2, and the four telescopic components 3 are arranged in an X shape along the circumferential direction of the connecting component 2. The telescopic direction of each telescopic component 3 is the inclined direction. When the telescopic component 3 expands and contracts, the height dimension and the width dimension of the installation space can be adjusted synchronously.

[0063] It should be noted that the fixing mechanism of the present application can be used to realize the fixed installation of objects to be fixed with different sizes. The object to be fixed can be a sheet structure or a block structure. In the following embodiments of the present application, the sheet-shaped filler 5 for batch installation is used as the object to be fixed for description.

[0064] In the above embodiment, the installation space can be adjusted to a predetermined size first, then the sheet-shaped filler 5 is placed into the fixing mechanism from the openings on the front and back sides (the front and back directions are the directions perpendicular to the length direction of the rod-passing component 1 in the horizontal plane), and then the rod-passing component 1 passes through the first connecting component 2, multiple fillers 5, and the second connecting component 2 in sequence. Finally, both ends of the rod-passing component 1 are fixedly connected to the connecting component 2. However, this installation method requires manual alignment of the through holes of multiple fillers 5 in a straight line, resulting in a large installation difficulty and low assembly efficiency.

[0065] To solve the above problems, in some embodiments of the present application, the rod-passing assembly 1 includes a first rod 11 and a second rod 12 that are detachably connected, and the first rod 11 and / or the second rod 12 are movably arranged on the connection assembly 2 corresponding to and connected thereto. When it is necessary to pass the sheet-shaped filler 5, the first rod 11 and the second rod 12 are separated, and then the first rod 11 or the second rod 12 is moved a certain distance towards the connection assembly 2 on its corresponding side, so that a gap appears between the first rod 11 and the second rod 12, facilitating the passing of the sheet-shaped filler 5 through the gap on the first rod 11 or the second rod 12, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, where Figure 3 the dotted arrow in represents the passing direction of the filler 5. During the passing process, there is no need for manual alignment of the through holes of multiple fillers 5 in a straight line, which can reduce the difficulty of batch installation of multiple fillers 5.

[0066] It should be noted that when installing the filler 5, the filler 5 can be installed piece by piece from the gap, or multiple fillers 5 with a total thickness less than the width of the gap can be installed in batches to achieve the left-right stacking of the fillers 5 on the first rod 11 and the second rod 12 (taking the length direction of the rod-passing assembly 1 as the left-right direction). Since the filler 5 is a flexible structure, after the filler 5 is filled, the filler 5 in the gap area can be pushed to the left and right sides to facilitate the reconnection of the first rod 11 and the second rod 12, making the rod-passing assembly 1 connected as a whole. After the overall connection of the rod-passing assembly 1 is completed, the filler 5 can return to its original state under its own elastic force, realizing the fitting between adjacent filler 5 sheets.

[0067] In some embodiments of the present application, the connection between the first rod 11 and the connection assembly 2 corresponding to and connected thereto is a movable connection. After the first rod 11 and the second rod 12 are separated, the first rod 11 can move along the Figure 3 solid arrow in, forming a gap between the first rod 11 and the second rod 12.

[0068] In some embodiments of the present application, the detachable connection between the first rod 11 and the second rod 12 can be achieved by screw connection, threaded connection, snap connection, etc. Since the reliability of screw connection and threaded connection is relatively strong, screw connection or threaded connection is preferably used to connect the first rod 11 and the second rod 12.

[0069] As a specific embodiment of the present application, the first rod 11 and the second rod 12 are detachably connected by a connecting member 13, and the connecting member 13 is preferably a screw, as Figure 4 shown.

[0070] In some embodiments of the present application, please refer toFigure 1 and Figure 3 , the frame component 4 includes a plurality of telescopic cross beam components; the first through rod 11 is a telescopic structure, and the telescopic direction of the cross beam component is parallel to the telescopic direction of the first through rod 11. The length adjustment of the fixing mechanism can be realized through the telescoping of the cross beam component and the first through rod 11, so as to realize the adjustment of the length dimension of the installation space, and further realize the adjustment of the installable quantity of the sheet packing 5 inside the installation space.

[0071] In some embodiments of the present application, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the first through rod 11 includes a screw rod 111 and a connecting rod 112. The screw rod 111 is rotatably arranged on the connecting component 2 connected thereto correspondingly. A screw hole matching the screw rod 111 is provided inside the connecting rod 112. One end of the connecting rod 112 is threadedly connected to the screw rod 111. By changing the threaded connection position between the screw rod 111 and the connecting rod 112, the overall length adjustment of the first through rod 11 can be realized, so as to realize the telescoping of the first through rod 11. The other end of the connecting rod 112 is detachably connected to the second through rod 12. When the second through rod 12 is fixedly arranged on the connecting component 2 connected thereto correspondingly, and the connecting rod 112 and the second through rod 12 are fixedly connected by screws, the connecting rod 112 can be prevented from rotating with the rotation of the screw rod 111. Furthermore, the telescoping of the first through rod 11 is realized by the rotation of the screw rod 111 relative to the connecting rod 112. When the screw rod 111 is screwed out of the connecting rod 112 (in the state of not being completely separated), the overall length of the first through rod 11 increases. At this time, the plurality of cross beam components extend along the Figure 3 solid arrow direction in the figure, and the overall length of the fixing mechanism can be increased; when the screw rod 111 is screwed into the connecting rod 112, the length of the through rod assembly 1 can be shortened, so as to reduce the distance between the connecting components 2 at both ends of the fixing mechanism, and realize the left and right pressing of the packing 5 stacked on the through rod assembly 1, which can avoid the appearance of gaps between adjacent packing 5 sheets and affect the heat exchange efficiency of the packing module. During the process of the screw rod 111 being screwed into the connecting rod 112, the plurality of cross beam components will also shrink accordingly, so that the overall length of the fixing mechanism is shortened, so as to facilitate the left and right pressing of the packing 5.

[0072] In some embodiments of the present application, please refer to Figure 2 and Figure 4, the first piercing rod 11 further includes a connecting cylinder 113. The connecting cylinder 113 is fixedly connected to the corresponding connecting component 2. The connecting cylinder 113 is sleeved outside the screw rod 111 and can be used to pierce the sheet-shaped filler 5, avoiding the direct contact between the outer peripheral surface of the screw rod 111 and the through hole on the filler 5, and avoiding the wear of the through hole on the filler 5 caused by the thread on the outer peripheral surface of the screw rod 111 during rotation, resulting in damage to the through hole and inability to realize the positioning of the filler 5 on the piercing rod assembly 1. The connecting rod 112 is slidably connected to the connecting cylinder 113. When it is necessary to disassemble the connecting piece 13 between the connecting rod 112 and the second piercing rod 12 to form a gap, the screw rod 111 and the connecting rod 112 can be moved towards the outside of the fixing mechanism, so that the connecting rod 112 partially or completely retracts into the connecting cylinder 113, facilitating the formation of a gap between the first piercing rod 11 and the second piercing rod 12 to realize the piercing of the filler 5.

[0073] In some embodiments of the present application, please refer to Figure 2 , Figure 3 and Figure 4 , the first piercing rod 11 further includes an operating handle 114. One end of the screw rod 111 far from the connecting rod 112 extends out of the connecting cylinder 113 and the connecting component 2 in sequence to realize the connection with the operating handle 114. One end of the screw rod 111 far from the connecting rod 112 is connected with an operating handle 114. The rotation of the screw rod 111 can be realized by rotating the operating handle 114 outside the fixing mechanism (i.e., on the side of the connecting component 2 far from the filler 5), so as to realize the adjustment of the threaded connection position between the screw rod 111 and the connecting rod 112, and the axial limit of the operating handle 114 is carried out through the connecting component 2, thereby realizing the length adjustment of the piercing rod assembly 1 and the left and right pressing of the filler 5.

[0074] In some embodiments of the present application, please refer to Figure 2 , Figure 3 and Figure 4 , the connecting component 2 is provided with a bearing seat 21. The screw rod 111 is inserted into the bearing seat 21. The screw rod 111 can axially move relative to the bearing seat 21. When the screw rod 111 or the operating handle 114 abuts against the bearing seat 21 of the connecting component 2, the rotation resistance of the screw rod 111 can be reduced through the bearing inside the bearing seat 21.

[0075] In some embodiments of the present application, please refer to Figure 2 , Figure 6 and Figure 7 , the connecting component 2 includes a plurality of hinge parts 22. The plurality of hinge parts 22 are correspondingly connected to the plurality of telescopic components 3, which can make the telescopic components 3 swing relative to the connecting component 2. Figure 6The direction of the solid arrow in it is the swinging direction of the corresponding telescopic component 3. The width adjustment of the fixing mechanism can be further realized through the swinging of the telescopic component 3, so as to realize the width adjustment of the installation space, facilitating the installation of the packing 5 with different width specifications.

[0076] In some embodiments of the present application, please refer to Figure 6 and Figure 7 , the connecting component 2 further includes a plurality of arc-shaped chutes 23, and the plurality of arc-shaped chutes 23 are arranged in one-to-one correspondence with the plurality of hinge parts 22. A limiting member 31 for inserting into the arc-shaped chute 23 is provided on the telescopic component 3. The swinging guidance of the plurality of telescopic components 3 can be realized through the sliding cooperation of the arc-shaped chute 23 and the limiting member 31, and the swinging range of the telescopic component 3 is limited by the arc length of the arc-shaped chute 23.

[0077] In some preferred embodiments of the present application, the swinging angle θ range of the telescopic component 3 is 0-80°. When θ is 0°, the telescopic component 3 is parallel to the vertical direction, and its swinging angle is less than 80°, which can avoid the telescopic component 3 swinging to the horizontal or near-horizontal state, and the vertical pressing force cannot be applied to the packing 5 through the telescopic component 3 and the frame component 4.

[0078] In some embodiments of the present application, please refer to Figure 1 and Figure 2 , the connecting component 2 further includes a first baffle 24 and a second baffle 25. The first baffle 24 and the second baffle 25 are connected through the hinge shaft of the hinge part 22. The telescopic component 3 is clamped between the first baffle 24 and the second baffle 25, and is connected into a whole with the first baffle 24 and the second baffle 25 through the hinge shaft of the hinge part 22. The hinge shaft of the hinge part 22 can specifically be a bolt assembly, which can realize the relative fixation of the first baffle 24 and the second baffle 25 while realizing the hinge with the telescopic component 3. A plurality of arc-shaped chutes 23 are opened on the first baffle 24, which can be used for swinging guidance and limiting of the telescopic component 3. The second baffle 25 is arranged on the inner side of the telescopic component 3 (i.e., the side close to the packing 5), which can increase the contact area between the connecting component 2 and the packing 5, and is beneficial to pressing the left and right ends of the batch-installed packing 5. The connecting cylinder 113 and the second through rod 12 are fixedly connected to the second baffle 25 on their corresponding sides, and the fixed setting of the connecting cylinder 113 and the second through rod 12 in the fixing mechanism can be realized.

[0079] In some embodiments of the present application, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7, the telescopic assembly 3 includes a sleeve 32, a sliding rod 33, and a detachable first fastener 34. The sleeve 32 is connected to the connecting assembly 2, specifically, the sleeve 32 is hinged to the hinge portion 22. The first end of the sliding rod 33 is slidably connected to the sleeve 32, and the telescopic assembly 3 is telescoped by sliding the sliding rod 33 relative to the sleeve 32. The second end of the sliding rod 33 is connected to the frame assembly 4 and can be used to drive the frame assembly 4 to move synchronously to adjust the size of the installation space; the first fastener 34 is respectively connected to the sleeve 32 and the sliding rod 33, and can be used to relatively fix the sleeve 32 and the sliding rod 33 after the telescopic adjustment is achieved, so as to avoid the size change of the fixing mechanism after the packing 5 is installed.

[0080] In some embodiments of the present application, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 , the first fastener 34 is a stop knob. The stop knob is threadedly connected to the sliding rod 33. There is a sliding groove 322 on the sleeve body 321 that matches the threaded section of the stop knob. When the stop knob is loosened, the sliding rod 33 slides in the sleeve 32, and the stop knob slides in the sliding groove 322. After the telescopic assembly 3 completes the telescopic adjustment, the stop knob is tightened so that the stop knob presses against the sleeve body 321, and a tight abutting state is also formed between the sliding rod 33 and the sleeve 32, which can limit the sliding of the sliding rod 33 inside the sleeve 32 and realize the relative fixation between the sliding rod 33 and the sleeve 32.

[0081] In some embodiments of the present application, the sliding rod 33 is hinged to the end of the frame assembly 4, and the connection angle between the sliding rod 33 and the frame assembly 4 can be adaptively adjusted when the telescopic assembly 3 swings, which can avoid the change of the contact position between the frame assembly 4 and the packing 5 caused by the swing of the telescopic assembly 3, and can avoid the frame assembly 4 supporting or pressing the packing 5 through the ridge line position, resulting in a poor supporting and fixing effect of the fixing mechanism on the packing 5.

[0082] In some embodiments of the present application, please refer to Figure 2 , Figure 6 and Figure 7 , the telescopic assembly 3 further includes an elastic member 35. The elastic member 35 is respectively connected to the sleeve 32 and the sliding rod 33. The elastic member 35 always has a tendency to make the sliding rod 33 slide towards the connecting assembly 2, and the telescopic assembly 3 is contracted under the elastic force of the elastic member 35, so that the frame assembly 4 connected to the sliding rod 33 can be pressed against the outer surface of the packing 5.

[0083] In some embodiments of the present application, the telescopic assembly 3 can be divided into an upper telescopic assembly 3a and a lower telescopic assembly 3b according to its installation position. Among them, the lower telescopic assembly 3b is connected to the lower side of the connecting assembly 2, and the gravity of the connecting assembly 2, the through-rod assembly 1, and the packing 5 is applied to the sleeve 32, which can realize the automatic locking between the sleeve 32 and the sliding rod 33. Therefore, there is no need to provide an elastic member 35 in the lower telescopic assembly 3b.

[0084] In some embodiments of the present application, please refer to Figure 1 , Figure 3 , Figure 8 and Figure 10 , a plurality of crossbeam assemblies include an upper crossbeam assembly 41 and a lower crossbeam assembly 42 arranged oppositely. The bottom of the packing 5 can be supported through the lower crossbeam assembly 42, and the top of the packing 5 can be pressed through the upper crossbeam assembly 41, so as to realize the fixation and pressing of multiple pieces of packing 5.

[0085] It should be noted that both ends of the crossbeam assembly are respectively connected to two telescopic assemblies 3 correspondingly arranged at both ends of the fixing mechanism, and a plurality of crossbeam assemblies are independent of each other, so as to facilitate the distance change between two adjacent crossbeam assemblies with the telescopic and / or swinging of the telescopic assembly 3, thereby realizing the width adjustment of the installation space.

[0086] In some embodiments of the present application, please refer to Figure 8 and Figure 9 , the upper crossbeam assembly 41 is provided with an abutting portion 411, and the abutting portion 411 faces the installation space and can be used to abut against the packing 5 inside the installation space. Since the sliding rod 33 is hinged to the end of the upper crossbeam assembly 41, the abutting portion 411 can always face the top of the packing 5 during the swinging of the upper telescopic assembly 3a, and the top of the packing 5 can always be pressed through the abutting portion 411.

[0087] In some embodiments of the present application, please refer to Figure 8 and Figure 9 , the abutting portion 411 includes a plurality of protruding structures extending towards the installation space, and the packing 5 can be embedded through the protruding structures, increasing the contact area and friction force between the abutting portion 411 and the packing 5, avoiding the displacement of the upper crossbeam assembly 41 after pressing the packing 5, and thus restricting the continuous swinging of the upper telescopic assembly 3a connected to the upper crossbeam assembly 41 after the packing 5 is pressed.

[0088] In some embodiments of the present application, the protruding structure can be a rib, a bump or other structures, all of which can achieve the purpose of the present application.

[0089] In some embodiments of the present application, please refer to Figure 8 and Figure 10, both the upper crossbeam assembly 41 and the lower crossbeam assembly 42 include a sleeve beam and a sliding beam that are slidably connected, which can be used to realize the synchronous telescoping of the upper crossbeam assembly 41 and the lower crossbeam assembly 42, thereby realizing the length adjustment of the fixing mechanism.

[0090] In some embodiments of the present application, please refer to Figure 3 and Figure 8 , the number of the upper crossbeam assemblies 41 is two, which are respectively connected to the two upper telescopic assemblies 3a correspondingly. The two upper crossbeam assemblies 41 are independent of each other, and the distance between them can change with the telescoping and / or swinging of the two upper telescopic assemblies 3a, so as to realize the adjustment of the top width of the installation space, so as to press the two sides (i.e., the front and back sides) of the top of the packing 5 that is pressed by the two upper crossbeam assemblies 41, as Figure 3 shown.

[0091] In some embodiments of the present application, the upper crossbeam assembly 41 includes a first sleeve beam 412, a first sliding beam 413 and a second sliding beam 414. A detachable second fastener 415 is provided on the first sleeve beam 412. The second fastener 415 is respectively connected to the first sleeve beam 412 and the first sliding beam 413, which can realize the relative fixation between the first sleeve beam 412 and the first sliding beam 413. The second sliding beam 414 is slidably arranged in the first sleeve beam 412, and the telescoping of the upper crossbeam assembly 41 can be realized by the relative sliding of the second sliding beam 414 with respect to the first sleeve beam 412.

[0092] In some embodiments of the present application, to avoid the setting of the abutting portion 411 affecting the relative sliding between the sliding beam and the sleeve beam, it is preferably to set the abutting portion 411 at one end of the sliding beam away from the sleeve beam, as Figure 9 shown; or the abutting portion 411 is set on the side of the first sleeve beam 412 facing the packing 5, which can increase the coverage range of the abutting portion 411 while avoiding affecting the movement of the sliding beam.

[0093] In some embodiments of the present application, the lower crossbeam assembly 42 includes a second sleeve beam 421 and a third sliding beam 422. The telescoping of the lower crossbeam assembly 42 can be realized by the relative sliding of the third sliding beam 422 with respect to the second sleeve beam 421.

[0094] In some embodiments of the present application, in order to enable the upper crossbeam assembly 41 and the lower crossbeam assembly 42 to expand and contract as the threaded connection position of the screw 111 and the connecting rod 112 in the first through rod 11 changes, no damping structure or limiting fastening structure is provided between the first sleeve beam 412 and the second sliding beam 414, and between the second sleeve beam 421 and the third sliding beam 422, which can reduce the expansion and contraction resistance of the upper crossbeam assembly 41 and the lower crossbeam assembly 42, and reduce the resistance when pressing the packing 5 by tightening the screw 111 and the connecting rod 112. At this time, the length of the second sliding beam 414 extending into the first sleeve beam 412 and the length of the third sliding beam 422 extending into the second sleeve beam 421 are both set long enough to prevent the sliding beam from disengaging from the sleeve beam.

[0095] In some embodiments of the present application, please refer to Figure 1 , Figure 3 and Figure 10 , the frame assembly 4 further includes a longitudinal beam assembly 43. The lower crossbeam assembly 42 and the longitudinal beam assembly 43 are connected to form a telescopic rectangular frame structure. Specifically, the telescopic direction of the rectangular frame is parallel to the telescopic direction of the lower crossbeam assembly 42, which can improve the structural strength of the frame assembly 4 while not affecting the telescopic ability of the frame assembly 4.

[0096] In some embodiments of the present application, the lower crossbeam assembly 42 further includes a fixed crossbeam 423. The longitudinal beam assembly 43 includes a plurality of longitudinal beams arranged along the length direction of the fixing mechanism. Both ends of the two fixed crossbeams 423, between the two second sleeve beams 421, and between the ends of the two third sliding beams 422 can be connected by longitudinal beams to form a frame structure with stable structure.

[0097] In some embodiments of the present application, the longitudinal beam assembly 43 includes a first longitudinal beam 431, a second longitudinal beam 432, and a third longitudinal beam 433. The first longitudinal beam 431 is connected to the ends of the two third sliding beams 422 (the end far from the second sleeve beam 421) and can move synchronously with the third sliding beam 422. The second longitudinal beam 432 is respectively connected to the two second sleeve beams 421 and the two fixed crossbeams 423 to form a stable H-shaped structure. The third longitudinal beam 433 is respectively connected to the two fixed crossbeams 423 to close one end of the H-shaped structure, thereby enhancing the structural strength of the bottom support structure formed by connecting the lower crossbeam assembly 42 and the longitudinal beam assembly 43.

[0098] It should be noted that the second sleeve beam 421 and the fixed crossbeam 423 can be an integrated structure or two independent beam structures, both of which can achieve the purpose of the present application.

[0099] It should be noted that when the longitudinal beam assembly 43 is connected to the lower crossbeam assembly 42, the change in the distance between the two lower crossbeam assemblies 42 in the width direction is restricted by the longitudinal beam. However, since the width between the two upper crossbeam assemblies 41 is adjustable, the width adjustment of the installation space can still be achieved through the upper crossbeam assembly 41. While enhancing the overall structural strength of the lifting frame assembly 4, the width dimension adjustment ability of the fixing mechanism can still be ensured.

[0100] Please refer to Figures 1 to 12 , the second aspect of the embodiment of the present application provides a packing module, including the fixing mechanism in the above embodiment, and further including multiple packing sheets 5. The packing sheets 5 are provided with through holes that are matched with the rod-passing assembly 1, and the packing sheets 5 can be threaded on the rod-passing assembly 1; multiple packing sheets 5 are arranged in the installation space, and the multiple packing sheets 5 can be pressed tightly inside the installation space through the rod-passing assembly 1, the connecting assembly 2, the telescopic assembly 3, and the frame assembly 4, so as to achieve the tight fit between adjacent packing sheets 5. Since the size of the installation space is adjustable, it can be applied to the installation of packing sheets 5 of various specifications, and assembled into packing modules of various specifications, such as Figure 11 shown.

[0101] Please refer to Figures 1 to 12 , the third aspect of the embodiment of the present application provides a cooling tower, including the packing module in the above embodiment, which can realize the modular installation of the packing sheets 5 and improve the assembly efficiency of the packing sheets 5 of the cooling tower.

[0102] In some embodiments of the present application, please refer to Figure 12 , the cooling tower further includes a base 6, a water distribution tray 7, a water collection tank 8, and a fan assembly 9. The frame assembly 4 in the fixing mechanism is fixedly connected to the base 6 to realize the fixed setting of the fixing mechanism and the packing module in the cooling tower. Specifically, the fixed crossbeam 423, the second sleeve beam 421, the second longitudinal beam 432, and the third longitudinal beam 433 in the frame assembly 4 can all be fixedly connected to the base 6 to improve the installation reliability of the packing module. A water distribution tray 7 is provided at the top of the packing module, and a water collection tank 8 is provided at the bottom of the packing module. The high-temperature circulating cooling water is evenly poured on the packing module through the water distribution tray 7. The fan assembly 9 at the top of the cooling tower keeps working, so that the cold air exchanges heat with the high-temperature circulating cooling water in the packing module to realize the cooling of the circulating cooling water, and then the heat-exchanged humid and hot air is discharged from the top of the cooling tower through the fan assembly 9. The cooled circulating cooling water drops into the water collection tank 8 below the packing module and is transported to the equipment to be cooled for recycling.

[0103] In some embodiments of the present application, please refer to Figures 1 to 12 , the assembly method of the above packing module is as follows:

[0104] Step 1: Adjust the lower telescopic component 3b to make the height of the rod-passing component 1 match the height of the through-hole on the packing 5; disassemble the first rod 11 and the second rod 12 to form a gap between them; perform telescopic adjustment on the upper crossbeam component 41 and the lower crossbeam component 42 to meet the installation requirements of a preset number of packings 5; preliminarily adjust the swing angle and telescopic degree of the upper telescopic component 3a so that the position of the upper crossbeam component 41 can contact both sides of the top of the packing 5.

[0105] Step 2: Thread multiple packings 5 onto the first rod 11 or the second rod 12, stack the packings 5 in batches from left to right until the entire installation space is filled with packings 5; push the packings 5 in the gap area to both left and right sides, and connect the first rod 11 and the second rod 12 through the connecting piece 13.

[0106] Step 3: Rotate the operating handle 114 to screw the screw 111 into the connecting rod 112, shortening the overall length of the first rod 11; until the operating handle 114 abuts against the bearing seat 21. During this process, the upper crossbeam component 41 and the lower crossbeam component 42 contract synchronously, and the connecting components 2 at both ends of the fixing mechanism abut against the packing 5, realizing the clamping of both left and right ends of the packing 5.

[0107] Step 4: Loosen the first fastener 34 of the upper telescopic component 3a. Under the action of the elastic member 35, the sliding rod 33 is subjected to a downward pulling force, and the upper crossbeam component 41 moves accordingly to realize the pressing of the top of the packing 5; the protruding structure of the abutting portion 411 is embedded in the packing 5, restricting the swing and displacement of the upper telescopic component 3a and the upper crossbeam component 41 while pressing the packing 5; then tighten the first fastener 34 of the upper telescopic component 3a.

[0108] Step 5: Loosen the first fastener 34 of the lower telescopic component 3b. Under the gravity of components such as the connecting component 2, the rod-passing component 1, and the packing 5, the lower telescopic component 3b is tightened, and then tighten the first fastener 34 of the lower telescopic component 3b.

[0109] The fixing mechanism of this application has a simple and reliable structure, is easy to manufacture and maintain. The packings 5 can be assembled in batches without pasting single packings 5 one by one, reducing labor costs and improving efficiency. It is convenient to adjust the installation quantity of the packing sheets 5 in the fixing mechanism, making the tightness of the fixing mechanism and the packings 5 more suitable for the tower type of the cooling tower. The cooling tower packing 5 is assembled and fixed by pressing, without external hoisting of the tower, which is convenient for later cleaning or replacement of the packing 5, saving maintenance costs and increasing the overall service life of the cooling tower equipment.
