[0002] In the fields of industrial production and central air-conditioning systems, etc., water-cooling cooling towers play a key cooling role. Its working principle is to let the cooling water carrying waste heat exchange heat with air in the tower, transfer the waste heat to the air and disperse it into the atmosphere, so as to realize the cooling of the circulating water. As an important part of the cooling tower, the water collector plays an indispensable role in the whole system. Its function is to recover the water droplets carried out by the air flow, reduce the waste of water resources, and at the same time reduce the impact on the surrounding environment.

[0003] The operating conditions of the cooling tower will vary due to changes in factors such as environmental temperature, humidity, and load. When the conditions change, the air flow velocity and direction will also change. Since the angles of the plates in the traditional water collector are fixed, the plates with fixed angles cannot be adjusted according to the actual air flow conditions, which will lead to a decrease in the collision efficiency between water droplets and the plates, and some water droplets cannot be effectively captured, thus reducing the water collection efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to: in order to solve the problem that the angles of the plates in the existing water collector are fixed and cannot be adjusted according to the actual air flow conditions, which will lead to a decrease in the collision efficiency between water droplets and the plates, and some water droplets cannot be effectively captured, thus reducing the water collection efficiency, an efficient water collector for cooling towers is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technology: an efficient water collector for cooling towers, including a frame, and a plurality of plate mechanisms are arranged inside the frame along its length direction;

[0006] The plate mechanism includes a first blade and a second blade hinged by a hinge, and an adjusting mechanism capable of adjusting the included angle between the first blade and the second blade is arranged on the frame through a fixing cover.

[0007] As a further description of the above technical solution: the adjusting mechanism includes an adjusting plate capable of sliding on the sliding groove on the inner wall of the frame, and the pin shaft of the hinge is fixedly connected with it through the positioning hole on the adjusting plate;

[0008] Limit end heads are arranged at both ends of the first blade and the second blade, and the limit end heads can move in the adjusting grooves opened on the inner wall of the frame along the direction perpendicular to the moving direction of the adjusting plate.

[0009] As a further description of the above technical solution: One end of the adjusting plate is provided with a connecting plate through a connecting shaft penetrating the frame, and the connecting plate is connected to the output end of a driving member fixed on the cooling tower through a driving rod.

[0010] As a further description of the above technical solution: The driving member fixed on the cooling tower is one of an electric push rod, a pneumatic push rod or a hydraulic push rod.

[0011] As a further description of the above technical solution: A slide rail is arranged on the chute, and a guiding groove matching with the slide rail is formed on the adjusting plate.

[0012] As a further description of the above technical solution: Convex strips integrally formed therewith protrude outward from the surfaces of the first blade and the second blade, and the number of the convex strips is at least two.

[0013] As a further description of the above technical solution: A humidity sensor is arranged on the fixing cover, and the detection probe of the humidity sensor is detachably mounted on the frame through a bracket.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0015] By adjusting the opening angle of the inner plate mechanism of the water collector, the performance of the water collector can be optimized according to the actual working conditions. In the high-temperature and high-humidity environment in summer, the opening angle of the plate mechanism can be appropriately reduced to increase the contact area and time between water droplets and the plate, improve the water collection efficiency, and reduce the evaporation loss of water. While in winter or under low-load operation, the opening angle can be increased to reduce the air flow resistance, ensure the ventilation performance of the cooling tower, and at the same time avoid the ice formation problem caused by excessive water collection. In addition, by appropriately adjusting the opening angle of the plate mechanism, the water droplets are more likely to collide with the plate under the action of inertia, thereby improving the water collection efficiency and reducing the escape rate of water droplets.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0026] Referring to Figures 1-7 , a highly efficient water collector for a cooling tower provided in this embodiment includes a frame 1, and a plurality of plate mechanisms 2 are arranged inside it along its length direction. The plate mechanism 2 includes a first blade 21 and a second blade 22 hinged by a hinge 23. An adjustment mechanism 4 capable of adjusting the included angle between the first blade 21 and the second blade 22 is provided on the frame 1 through a fixed cover 3. The adjustment mechanism 4 includes an adjustment plate 41 that can slide on the slide groove 12 on the inner wall of the frame 1. The pin shaft of the hinge 23 is fixedly connected to it through the positioning hole 45 on the adjustment plate 41. Limit ends 24 are provided at both ends of the first blade 21 and the second blade 22, and the limit ends 24 can move in the adjustment groove 11 opened on the inner wall of the frame 1 perpendicular to the moving direction of the adjustment plate 41. A slide rail 13 is provided on the slide groove 12, and a guide groove 46 matching the slide rail 13 is opened on the adjustment plate 41.

[0027] In the present utility model, the water collector is installed in the cooling tower through its frame 1. Water in the cooling tower is sprayed downward from the top and contacts with hot air to form hot steam and water droplets. The fan drives the air flow to make the humid hot air rise. When the humid hot air passes through the water collector, the water droplets therein will be blocked by the first blade 21 and the second blade 22 of the water collector and adhere to them. The water droplets gradually accumulate. When the gravity is greater than the adhesion force, they will fall and return to the water tank or adhere to the condensation coil again for evaporation, thus achieving the purpose of water collection. When adjusting the included angle between the first blade 21 and the second blade 22 according to the working conditions, the adjusting plate 41 of the adjusting mechanism 4 slides on the sliding groove 12 on the inner wall of the frame 1. Since the pin shaft of the hinge 23 is fixedly connected to the positioning hole 45 on the adjusting plate 41, the movement of the adjusting plate 41 will drive the hinge 23, and then make the first blade 21 and the second blade 22 rotate around the hinge 23, changing the included angle between the two. During this process, the slide rail 13 and the guide groove 46 cooperate with each other to ensure that the adjusting plate 41 moves in a straight line during the movement, so as to accurately adjust the included angle between the first blade 21 and the second blade 22. The cooperation between the limit end 24 and the adjusting groove 11 ensures that the first blade 21 and the second blade 22 will not shift or be misaligned during the process of adjusting the included angle, ensuring the accuracy and stability of the angle adjustment. By adjusting the included angle between the first blade 21 and the second blade 22, the water collector can adjust the plate angle according to different operating conditions of the cooling tower, improving the water collection efficiency;

[0028] Among them, as Figure 1 , Figures 3-5 shown, one end of the adjusting plate 41 is provided with a connecting plate 43 through a connecting shaft 42 penetrating the frame 1, and the connecting plate 43 is connected to the output end of a driving member fixed on the cooling tower through a driving rod 44. The linear motion of the output end of the driving member is transmitted to the connecting plate 43 through the driving rod 44. Since the connecting plate 43 is fixedly connected to the connecting shaft 42, the connecting shaft 42 penetrates the frame 1 and is connected to the adjusting plate 41, so the movement of the connecting plate 43 drives the connecting shaft 42 and the adjusting plate 41 to slide on the sliding groove 12 on the inner wall of the frame 1, and then adjusts the included angle between the first blade 21 and the second blade 22 in the plate mechanism 2;

[0029] It should be noted that the driving member fixed on the cooling tower adopts one of an electric push rod, a pneumatic push rod or a hydraulic push rod. Preferably, the driving member is selected as an electric push rod. The electric push rod is driven by a motor and, in cooperation with a precise transmission mechanism and a position sensor, can achieve precise control of the moving distance of the adjusting plate 41, so as to accurately adjust the included angle of the water collector plates.

[0030] Specifically, as Figure 3As shown in the figure, ridges 25 integrally formed with and protruding outward are provided on the surfaces of the first blade 21 and the second blade 22. The number of the ridges 25 is at least two. When the airflow containing water droplets passes through the water collector blades, the ridges 25 will cause the airflow to form a complex flow field on the blade surfaces. On the one hand, the ridges 25 increase the contact area between the airflow and the blades, making it easier for the water droplets in the airflow to adhere to the blade surfaces. On the other hand, the ridges 25 change the flow path of the airflow, causing small vortices to form around the ridges 25, which helps to capture the tiny water droplets in the airflow and improve the water collection efficiency.

[0031] Specifically, as Figure 1 shown in the figure, a humidity sensor 5 is provided on the fixed cover 3. The detection probe of the humidity sensor 5 is detachably mounted on the frame 1 through a bracket. The humidity sensor 5 can be used to monitor the air humidity around the water collector in real time. According to the humidity information fed back by the humidity sensor 5, the included angle between the first blade 21 and the second blade 22 is adjusted through the adjusting mechanism 4 to optimize the water collection effect, so that the water collector can maintain a high efficiency under different working conditions. Among them, the humidity sensor 5 uses a sensor with the model number OSA-3.

[0032] As described above, only the preferred specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
