[0001] The utility model relates to the technical field of high-level water collecting troughs, in particular to a high-level water collecting trough for a cooling tower. Background Technique
[0002] Circulating water systems with large-scale thermal power generation as the background increasingly adopt high-level water collecting cooling towers. Since the high-level water collecting cooling towers cancel the ground collecting pool and raise the water collecting system above the air inlet, the head of the circulating pump is reduced, the electricity consumption of the circulating pump is saved, and at the same time, the noise impact is also reduced.
[0003] Existing high-level water collecting troughs are made by the fiberglass manual hand lay-up process. When using fiberglass hand lay-up molding, a large number of molds must be invested, and the number of molds also increases as the scale of the high-level water collecting cooling tower becomes larger. At the same time, certain toxic and harmful gases are released during the molding process of the high-level water collecting trough, which is harmful to health and requires relatively high environmental protection facilities for the production site, resulting in increased processing costs. At the same time, the high-level water collecting trough is generally connected by flanges, and leakage accidents are likely to occur after long-term use, causing waste of water resources.

[0021] As Figure 1 and Figure 2 shown, the present utility model provides a technical solution for a high-level water receiving groove of a cooling tower, including a U-shaped groove section 1, an R-shaped groove section 2 is connected to the upper end of the U-shaped groove section 1, a lifting hole 4 is provided on the inner wall of the U-shaped groove section 1, a longitudinal reinforcing rib 5 is longitudinally provided on the U-shaped groove section 1, a transverse reinforcing rib 6 is transversely provided on the U-shaped groove section 1, and the longitudinal reinforcing rib 5 and the transverse reinforcing rib 6 are arranged at equal distances on the curve of the U-shaped groove section 1. At the same time, the longitudinal reinforcing rib 5 and the transverse reinforcing rib 6 are all arranged outside the U-shaped groove section 1. Flanges 3 are provided at both ends of the U-shaped groove section 1 and the R-shaped groove section 2, perforations 7 are provided on the flanges 3, a detection mechanism 14 is provided at the port of the U-shaped groove section 1. The U-shaped groove section 1 and the R-shaped groove section 2 are integrally formed by an injection molding process without further secondary processing, and the detection mechanism 14 can detect the water flow rate of seepage water, so as to judge whether the leakage situation is serious.
[0022] As Figure 2 and Figure 3 shown, docking screw holes 10 are provided at the connection between the U-shaped groove section 1 and the R-shaped groove section 2, and the docking screw holes 10 are arranged in a triangular pattern on the U-shaped groove section 1 and the R-shaped groove section 2. A convex triangle 8 is provided on one side of the docking screw hole 10, a triangular groove 9 is provided on the other side of the docking screw hole 10, a docking bolt 11 is provided in the docking screw hole 10, and the R-shaped groove section 2 is fixed on the U-shaped groove section 1 through the docking bolt 11.
[0023] Specifically, the U-shaped groove section 1 and the R-shaped groove section 2 are integrally formed by an injection molding process, without the need for secondary processing, and no embedded parts of any different materials are required, avoiding the influence of shrinkage deformation caused by temperature changes of different materials during use on the product. Moreover, the U-shaped groove section 1 and the R-shaped groove section 2 are meshed with a convex triangle 8 and a triangular groove 9 in cross-section, which can reduce the occurrence of leakage.
[0024] As Figure 1 and Figure 4 shown, flanges 3 are provided at both ends of the U-shaped groove section 1 and the R-shaped groove section 2. Through holes 7 are formed in the flanges 3. The detection mechanism 14 includes an arc-shaped water receiving tank 1401 arranged at the flange 3. A drain port 1404 is fixedly installed at the bottom of the arc-shaped water receiving tank 1401. A drain pipe 1406 is connected to the drain port 1404. A water flow sensor 1405 is provided on the drain pipe 1406. The detection mechanism 14 further includes a positioning bracket 1402 fixed on the arc-shaped water receiving tank 1401. A connection through hole 1403 is formed in the positioning bracket 1402.
[0025] Specifically, after the joint of the U-shaped groove section 1 leaks, the arc-shaped water receiving tank 1401 can catch the leaked water. The water will collect at the bottom of the arc-shaped water receiving tank 1401 and be discharged through the drain port 1404. The water discharged through the drain port 1404 can be re-discharged into a designated catch basin through the drain pipe 1406, reducing the waste of water resources. Moreover, the water flow sensor 1405 on the drain pipe 1406 can detect the water flow rate in the drain pipe 1406, so as to judge whether the leakage situation is serious.
[0026] Working principle: When in use, first install the entire device on the secondary beam by means of the hanging bracket 12 and the suspension rod 13. Then, assemble the U-shaped trough section 1 together using the flange 3. The R-shaped trough section 2 can receive the water showered from above and let it flow into the U-shaped trough section 1 below. The U-shaped trough section 1 can make the water flowing into the trough drain into the designated sump along the slope required by the design. During the use process, it is inevitable that water leakage occurs at the joints of the U-shaped trough section 1. After water leakage occurs at the joints of the U-shaped trough section 1, the arc-shaped water receiving trough 1401 can catch the leaked water. The water caught by the arc-shaped water receiving trough 1401 will gather at its bottom and be discharged through the drain port 1404. The water discharged through the drain port 1404 can be re-discharged into the designated sump through the drain pipe 1406, reducing the waste of water resources. Moreover, the water flow sensor 1405 on the drain pipe 1406 can detect the water flow rate in the drain pipe 1406, so as to judge whether the water leakage situation is serious. And an alarm can be connected to the water flow sensor 1405 to remind the user to repair in time when the water leakage situation is serious. The U-shaped trough section 1 and the R-shaped trough section 2 are connected by butt bolts 11 in the cross section; and the bolts are arranged in a triangular shape on the plane to ensure the structural stability. At the same time, the U-shaped trough section 1 and the R-shaped trough section 2 are meshed with the convex triangle 8 and the triangular groove 9 in the cross section to ensure leak prevention.
