[0033] The function of a cooling tower is to exchange heat between circulating water carrying waste heat and the air inside the tower. During the heat exchange process, the heat of the circulating water is transferred to the air and finally merged into the atmosphere, achieving the purpose of cooling the circulating water. The high-level water collection device is installed below the water distribution packing of the high-level water collection cooling tower. It is a device that collects water droplets falling from the packing into a high-level collection trough. Current high-level water collection devices consist of components such as a water collection ramp, splash guard, water collection trough, hangers, and a suspension assembly. The suspension assembly connects to the hangers to fix the water collection trough and the water collection ramp. The water collection ramp is installed at a certain angle between the packing and the collection trough, intercepting and guiding the water droplets falling from the packing to the collection trough.
[0034] However, for large-volume cooling towers, the water collection ramps installed inside are usually spliced together. However, the current water collection ramps have limited structural strength, and the splices of the water collection ramps are mostly simply fixed with bolts, resulting in poor sealing and a large risk of water seepage and leakage, which in turn affects the performance.
[0035] Therefore, this application provides a water-collecting inclined plate, which improves the structural strength of the water-collecting inclined plate to a certain extent without affecting its water-collecting performance, while improving its water-collecting and water-conducting performance and reducing the occurrence of water seepage and leakage.
[0036] See Figure 1 and Figure 2 One embodiment of this application provides a water-collecting ramp, including a corrugated plate 1, a first overlapping member 2, and a second overlapping member 3. The corrugated plate 1, through its corrugated structure, provides a channel for water flow to enter the water-collecting trough and, to a certain extent, improves the structural strength of the water-collecting ramp. The corrugated plate 1 has a first end and a second end that are opposite to each other along a first direction. The first overlapping member 2 and the second overlapping member 3 are respectively disposed on the first end and the second end, so that adjacent water-collecting ramps can be connected to each other through the first overlapping member 2 and the second overlapping member 3.
[0037] For specific settings, please refer to Figures 2-4 The first overlapping member 2 has a bent connecting section 21 and a flat overlapping section 22. The flat overlapping section 22 is spaced apart from the corrugated plate member 1 along a first direction. The bent connecting section 21 is located at the first end and is connected to the flat overlapping section 22. The second overlapping member 3 is located at the second end. The second overlapping member 3 has an overlapping surface 31 parallel to the flat overlapping section 22, and a reinforcing fixing point 32 is provided on the overlapping surface 31.
[0038] When the two adjacent water collecting inclined plates are connected, the planar lapping section 22 of one of the water collecting inclined plates can be lapped with the second lapping piece 3 of the other water collecting inclined plate, and the lapping surface 31 is directed towards the planar lapping section 22, and then a sealing piece is arranged between the lapped planar lapping section 22 and the second lapping piece 3, the two side surfaces of the sealing piece are respectively abutted with the planar lapping section 22 and the lapping surface 31, and the reinforcing fixing point 32 on the lapping surface 31 is sunk into the sealing piece, so as to effectively improve the connection stability and the sealing effect.
[0039] In summary, the water collecting inclined plate of the present application is provided with the corrugated plate piece 1 with the corrugated structure, so that the water collecting inclined plate can improve the structural strength without affecting the water collecting performance, and the first lapping piece 2 and the second lapping piece 3 are arranged, so that when the two adjacent water collecting inclined plates are connected, the planar lapping section 22 of one of the water collecting inclined plates can be lapped with the second lapping piece 3 of the other water collecting inclined plate, so as to effectively improve the connection stability and the sealing effect, and improve the overall structural strength by increasing the thickness, and the reinforcing fixing point 32 on the second lapping piece 3 can further improve the structural tightness between the second lapping piece 3 and the sealing piece, so as to improve the sealing effect, and solve the problem of water seepage and leakage at the splicing position, and affect the use effect.
[0040] Referring to Figure 1 and Figure 2 In one embodiment, the length of the second lapping piece 3 along the first direction is greater than or equal to the length of the planar lapping section 22 along the first direction, so that the first lapping piece 2 is lapped on the second lapping piece 3 through the planar lapping section 22. It can be understood that since the planar lapping section 22 is connected with the corrugated plate piece 1 through the bending connecting section 21, compared with the way that the top surface of the planar lapping section 22 is lapped with the bottom surface of the second lapping piece 3 and connected, the bottom surface of the planar lapping section 22 is lapped with the top surface of the second lapping piece 3 is more stable, and is more convenient for connection. Therefore, by making the length of the second lapping piece 3 along the first direction greater than or equal to the length of the planar lapping section 22 along the first direction, the planar lapping section 22 can be stably lapped on the second lapping piece 3.
[0041] In one embodiment, the second lapping piece 3 is a planar structure parallel to the planar lapping section 22, so that the two side surfaces of the second lapping piece 3 perpendicular to the first direction can be used as the lapping surface 31, so that the second lapping piece 3 is lapped with the planar lapping section 22.
[0042] Specifically, the planar lapping section 22 is parallel to the first direction, and the second lapping piece 3 is also parallel to the first direction with the planar lapping section 22, so that the two water collecting inclined plates after lapping can still be parallel to the first direction, and the water guiding effect is guaranteed.
[0043] Compared with the arc surface, the bending surface formed by two planar surfaces has greater strength. Therefore, referring toFigure 2 and Figure 3 In one embodiment, the bent connecting section 21 comprises a first planar connecting section 211 and a second planar connecting section 212, the first planar connecting section 211 is arranged at the first end portion and connected with the second planar connecting section 212.
[0044] Specifically, in the embodiment, one end of the first planar connecting section 211 is connected with the first end portion, the other end of the first planar connecting section 211, which is away from the first end portion, is connected with the second planar connecting section 212, and one end of the second planar connecting section 212, which is away from the first planar connecting section 211, is connected with the planar overlapping section 22. In order to ensure that the planar overlapping section 22 can be arranged at intervals with the corrugated board piece 1 along the first direction, the included angle between the first planar connecting section 211 and the second planar connecting section 212 is obtuse.
[0045] Referring to Figure 1 and Figure 2 In one embodiment, the corrugated board piece 1 comprises a plurality of valley sections 11 and a plurality of peak sections 12, which are arranged at intervals along the first direction, the first end portion is arranged on a valley section 11, and the second end portion is arranged on a peak section 12. Specifically, each valley section 11 is connected with two peak sections 12 at two ends along the first direction, respectively, and each valley section 11 cooperates with the two peak sections 12 on its two sides to form a water guide groove for guiding water flow. The first end portion is arranged on a valley section 11 so that the first overlapping piece 2 is connected with the valley section 11, and the second end portion is arranged on a peak section 12 so that the second overlapping piece 3 is connected with the peak section 12.
[0046] Referring to Figure 2 and Figure 3 In one embodiment, the peak section 12 comprises a planar connecting portion 121 and two bent reinforcing portions 122, the two bent reinforcing portions 122 are symmetrically arranged at two ends of the planar connecting portion 121 along the first direction, the structure of the bent reinforcing portion 122 is consistent with the structure of the bent connecting section 21, and the length of the planar connecting portion 121 along the first direction is greater than the length of the planar overlapping section 22 along the first direction. Specifically, the length of the planar connecting portion 121 along the first direction is equal to twice the length of the planar overlapping section 22 along the first direction. In this way, the structure of the first overlapping piece 2 is consistent with the structure of half of the peak section 12, and thus, when the water collecting apron is produced, the first overlapping piece 2 can be formed by only cutting off half of the peak section 12, which facilitates the production of the water collecting apron.
[0047] In one of the embodiments, the valley section 11 is a planar structure parallel to the first direction, and the length of the valley section 11 along the first direction is greater than the length of the second lap joint 3 along the first direction. Specifically, the length of the valley section 11 along the first direction is equal to twice the length of the second lap joint 3 along the first direction. In this way, the structure of the second lap joint 3 is consistent with the structure of the half valley section 11, and thus, when the water collecting slope is produced, the second lap joint 3 can be formed by only cutting the water collecting slope at the half of the valley section 11, which facilitates the production of the water collecting slope.
[0048] According to another aspect of the present application, a high-level water collecting device is provided, which comprises a water collecting tank and a water collecting slope according to any one of the above embodiments, and the water collecting slope is arranged at the tank opening of the water collecting tank. Specifically, the top and bottom of the water collecting slope are located at the filler bottom and the tank opening of the water collecting tank, respectively, so as to guide the cooling water falling from the filler bottom into the water collecting tank through the water collecting slope.
[0049] In one of the embodiments, the high-level water collecting device further comprises a sealing member, and two water collecting slopes are arranged, and the sealing member is arranged between the first lap joint 2 of one of the water collecting slopes and the second lap joint 3 of the other water collecting slope, and the sealing member is in abutment with the reinforcing fixing point 32 on the second lap joint 3. Specifically, the two opposite sides of the sealing member are in abutment with the planar lap joint section 22 of the first lap joint 2 and the lap joint surface 31 of the second lap joint 3, respectively, so as to improve the sealing effect between the first lap joint 2 and the second lap joint 3 through the sealing member, and thus improve the sealing effect of the two adjacent water collecting slopes after being connected, and solve the problem that the water seepage and leakage risk at the joint affects the use effect.
[0050] In summary, the high-level water collecting device of the present application has the corrugated plate 1 with the corrugated structure, so that the water collecting slope can improve the structural strength of itself without affecting the water collecting performance, and through the arrangement of the first lap joint 2 and the second lap joint 3, the planar lap joint section 22 of one of the water collecting slopes can be lap jointed with the second lap joint 3 of the other water collecting slope when the two adjacent water collecting slopes are connected, so as to effectively improve the connection stability and the sealing effect, and improve the overall structural strength by increasing the thickness, and the reinforcing fixing point 32 on the second lap joint 3 can further improve the structural compactness between the second lap joint 3 and the sealing member, and thus improve the sealing effect, and solve the problem that the water seepage and leakage risk at the joint affects the use effect.
[0051] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.
[0052] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
