Description

Technical Field

[0001] This invention relates to the field of cooling tower water collector technology, specifically an adjustable cooling tower water collector. Background Technology

[0002] As a key component of cooling towers, the water collector's core function is to intercept water droplets carried by the airflow during the circulating water spraying process, reducing water loss and wet pollution of the surrounding environment. At the same time, it must also ensure the smooth ventilation of the cooling tower to avoid reducing cooling efficiency due to excessive airflow resistance.

[0003] Existing cooling tower water collectors mostly use fixed installation structures for their water collection plates, which cannot be flexibly adjusted in terms of angle and plate spacing, making it difficult to adapt to changes in wind speed and water volume under different operating conditions. In summer, when the temperature and humidity are high and the wind speed is high, the fixed spacing can easily lead to an increase in water droplet entrainment and a decrease in water collection efficiency. In winter, under low flow and low wind speed conditions, the fixed angle will increase ventilation resistance and affect the cooling effect, resulting in an ineffective coordination between water collection efficiency and ventilation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable cooling tower water collector, which solves the problem mentioned in the background art that the water collection plates of existing cooling tower water collectors are mostly fixed installation structures, and their angles and plate spacing cannot be flexibly adjusted, making it difficult to adapt to changes in wind speed and water volume under different operating conditions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable cooling tower water collector, comprising a tower body and a main frame, wherein two parallel fixed rods are fixedly connected to the center of the front and rear surfaces of the main frame, and a plurality of round rods are provided on the inner side of the gap between the two fixed rods, wherein water collection plate assemblies are provided on the surface of the round rods for water collection operations, and adjusting assemblies are provided on the front and rear surfaces of the main frame for adjusting the angle and spacing of the water collection plate assemblies; A support plate is welded to the bottom opening of the ventilation vent of the tower body. A transmission component is provided on the bottom surface of the support plate. The transmission component includes an active transmission disc and a driven transmission disc, which are used to drive the water collection plate assembly to swing back and forth.

[0006] In this technical solution, the upper and lower water collection plates are connected by round rods. By adjusting the synchronous frame and crossbar in the assembly, the synchronous frame moves along the slide groove, driving the crossbar to move as well. This causes all the round rods to move laterally, and the water collection plates move accordingly, stretching or contracting the telescopic rods at both ends. This causes the channel angle formed by adjacent water collection plates to tilt and the spacing to change synchronously. This structure can precisely adapt to different wind speeds and water volume conditions, enhancing the water droplet interception effect while also considering ventilation efficiency, significantly improving the adaptability and flexibility of the water collector.

[0007] Preferably, the water collection plate assembly includes an upper water collection plate and a lower water collection plate, and a plurality of sleeves are fixedly connected to the bottom of the upper water collection plate and the top of the lower water collection plate. The sleeves are fitted onto the surface of the round rod and are slidably connected to the round rod.

[0008] In practical applications, the sliding fit between the sleeve and the round rod allows the upper and lower water collection plates to move synchronously with the round rod, while also allowing the water collection plates to finely adjust their posture relative to the round rod, providing a structural basis for angle and spacing adjustment.

[0009] Preferably, the top and bottom of the main frame are fixedly connected to several front-to-back force-bearing rods. The front and back edges of the force-bearing rods facing the inside of the main frame are rotatably connected to a storage frame via a hinge seat. The inner side of the storage frame is slidably connected to a telescopic rod, and a spring is fixedly connected between the telescopic rod and the inner wall of the storage frame. The outer end of the telescopic rod is rotatably connected to the upper or lower water collection plate in the water collection plate assembly via a hinge seat.

[0010] In practical applications, when adjusting the water collection plate, the telescopic rod extends and retracts within the storage frame as the water collection plate moves. The spring is simultaneously stretched or compressed to generate elastic force, providing buffer and reset support for the water collection plate, while avoiding adjustment jamming caused by the rigid connection between the water collection plate and the main frame.

[0011] Preferably, the adjustment assembly includes a timing frame and crossbars. The front and rear surfaces of the main frame are provided with two sliding grooves. The two ends of the timing frame are located inside the front and rear sliding grooves and are slidably connected to the main frame through the sliding grooves. The front and rear surfaces of the timing frame are welded with crossbars, and the two crossbars are fixedly connected to the front and rear ends of all the round rods respectively.

[0012] In practical applications, pushing the synchronous frame to move laterally along the slide rail will cause the crossbar to drive all the round bars to move synchronously, thereby driving all the water collection plate components to adjust their angles and spacing in a unified manner, achieving synchronous adjustment without the need to adjust the water collection plates one by one, making the operation convenient and efficient.

[0013] Preferably, the surface of the synchronization frame is threaded with a positioning bolt, and the main frame sidewall corresponding to the horizontal height of the positioning bolt is provided with a plurality of positioning holes, and the inner wall of the positioning hole is provided with a thread groove corresponding to the surface of the positioning bolt.

[0014] In practical applications, after the water collection plate is adjusted to the target state, tighten the positioning bolts to make it fit into the corresponding positioning holes. The timing frame position is locked by the thread engagement to prevent displacement. Multiple sets of positioning holes provide multiple adjustment options to adapt to different working conditions and improve the flexibility of use.

[0015] Preferably, the active drive disk is rotatably connected to the bottom center of the support plate, and a number of impeller blades are fixedly connected in a circular array at the top of the central shaft of the active drive disk, with the impeller blades and the active drive disk located on the upper and lower sides of the support plate respectively.

[0016] In practical applications, when the cooling tower fan drives the airflow upward, the airflow impacts the impeller blades, driving the impeller blades to rotate the active transmission disc, converting the airflow kinetic energy into mechanical transmission power. No additional power source is required, making it energy-saving and environmentally friendly.

[0017] Preferably, a driven transmission disc is rotatably connected to the inner top of the tower body, and the driven transmission disc and the driving transmission disc are connected to each other by a transmission belt. A drive disc is fixedly connected to the bottom center of the driving transmission disc.

[0018] In practical applications, when the active drive disc rotates, it transmits power to the driven drive disc via a transmission belt. The driven drive disc then drives the bottom drive disc to rotate synchronously, thus achieving power transmission.

[0019] Preferably, a drive rod is fixedly connected to the center of the top of the synchronization frame, and a push-pull rod is provided between the drive rod and the drive disk. The two ends of the push-pull rod are respectively rotatably connected to the drive rod and the drive disk.

[0020] In practical applications, when the drive disc rotates, the drive rod is pulled by the eccentrically connected push-pull rod to perform reciprocating linear motion. The drive rod drives the synchronous frame to move back and forth along the slide, which in turn causes the water collection plate assembly to swing. The purely mechanical linkage has a rapid response, no electrical components, a low failure rate, and is easy to maintain.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention incorporates several water-collecting plate assemblies within the main frame. The upper and lower water-collecting plates are connected by round rods. By adjusting the synchronizing frame and crossbars within the assembly, the synchronizing frame moves along a sliding groove, causing the crossbars to move as well. This results in all the round rods moving laterally, causing the water-collecting plates to move accordingly and extend or retract the telescopic rods at both ends. This causes the channel angle formed by adjacent water-collecting plates to tilt and the spacing to change synchronously. This structure can precisely adapt to different wind speeds and water volume conditions, enhancing water droplet interception while maintaining ventilation efficiency, significantly improving the adaptability and flexibility of the water collector.

[0022] 2. This invention, through the setting of a transmission component, uses a fan at the top of the tower to drive the airflow upward. The airflow drives the impeller and the active transmission disc to rotate, and then drives the driven transmission disc to rotate via a transmission belt. Next, it passes through the drive disc, push-pull rod, and drive rod at the bottom, causing the synchronous frame and crossbar to drive all the round rods to move back and forth. This causes each water collection plate assembly to swing back and forth, constantly changing the spacing and angle, thereby breaking the airflow gradient, increasing the probability of airflow colliding with the water collection plate, efficiently separating water vapor, and further improving water collection efficiency. At the same time, the pure mechanical structure has lower maintenance costs. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of the present invention easier to understand, the following detailed description is provided in conjunction with specific embodiments.

[0026] An adjustable cooling tower water collector, see [link / reference] Figures 1 to 8The system includes a tower body 1 and a main frame 9. Two parallel fixed rods 901 are fixedly connected to the center of the front and rear surfaces of the main frame 9. Several round rods 10 are provided on the inner side of the gap between the two fixed rods 901. The surface of the round rods 10 is provided with a water collection plate assembly for water collection. The water collection plate assembly includes an upper water collection plate 111 and a lower water collection plate 112. Several sleeves 11 are fixedly connected to the bottom of the upper water collection plate 111 and the top of the lower water collection plate 112. The sleeves 11 are fitted on the surface of the round rods 10 and are slidably connected to the round rods 10. Furthermore, the front and rear surfaces of the main frame 9 are equipped with adjustment components for adjusting the angle and spacing of the water collection plate components. The adjustment components include a timing frame 8 and a crossbar 803. The front and rear surfaces of the main frame 9 are equipped with two sliding grooves 903. The two ends of the timing frame 8 are located inside the front and rear sliding grooves 903 respectively and are slidably connected to the main frame 9 through the sliding grooves 903. The front and rear surfaces of the timing frame 8 are welded with crossbars 803. The two crossbars 803 are fixedly connected to the front and rear ends of all the round rods 10 respectively.

[0027] In the above technical solution, the water collection plate assembly slides with the round rod 10 through the sleeve 11, providing a structural basis for angle and spacing adjustment. During adjustment, the synchronous frame 8 moves laterally along the slide groove 903. The synchronous frame 8 drives all the round rods 10 to move synchronously through the crossbar 803. During the movement of the round rods 10, the upper water collection plate 111 and the lower water collection plate 112 move synchronously, while the telescopic rods 121 at both ends are stretched or contracted, so that the angle of the water collection channel formed between adjacent water collection plate assemblies gradually tilts, and the spacing also changes synchronously. This structure realizes convenient adjustment of the water collection angle and spacing, and can be flexibly adapted to changes in wind speed and water volume under different working conditions. When the wind speed is high, the spacing is reduced and the angle is increased to enhance water droplet interception. When the wind speed is low, the spacing is increased and the angle is decreased to reduce ventilation resistance, balancing water collection efficiency and ventilation smoothness, and greatly improving the adaptability of the water collector to different working conditions.

[0028] Specifically, such as Figure 5 and Figure 8 As shown, several front-to-back force-bearing rods 902 are fixedly connected to the top and bottom of the main frame 9. The front and back edges of the force-bearing rods 902 facing the inner side of the main frame 9 are rotatably connected to the storage frame 12 through hinge seats. The inner side of the storage frame 12 is slidably connected to the telescopic rod 121, and a spring 122 is fixedly connected between the telescopic rod 121 and the inner wall of the storage frame 12. The outer end of the telescopic rod 121 is rotatably connected to the upper water collection plate 111 or the lower water collection plate 112 in the water collection plate assembly through hinge seats.

[0029] In the above technical solution, the storage frame 12 provides installation and storage space for the telescopic rod 121 and the spring 122. The telescopic rod 121 is connected to the water collection plate assembly through a hinge seat. When the water collection plate assembly moves with the round rod 10 to adjust the angle and spacing, the telescopic rod 121 will extend and retract within the storage frame 12 according to the displacement direction of the water collection plate, and the spring 122 will stretch or compress accordingly. This structure provides buffer and reset support for the adjustment of the water collection plate assembly, allowing the upper water collection plate 111 and the lower water collection plate 112 to tilt smoothly, effectively avoiding the adjustment jam caused by the rigid connection between the upper and lower ends of the water collection plate assembly, ensuring a smooth and stable adjustment process, and improving the structural reliability and service life of the water collector.

[0030] Furthermore, such as Figure 4 As shown, a positioning bolt 801 is threaded through and screwed onto the surface of the synchronization frame 8. Several positioning holes 802 are provided on the side wall of the main frame 9 corresponding to the horizontal height of the positioning bolt 801. The inner wall of the positioning hole 802 has a threaded groove corresponding to the surface of the positioning bolt 801. When the water collection plate assembly is adjusted to the appropriate angle and spacing for the working condition, the positioning bolt 801 is rotated so that its end screws into the corresponding positioning hole 802, achieving a fixed lock between the synchronization frame 8 and the main frame 9 through thread engagement. If further adjustment is needed, the positioning bolt 801 is rotated in the opposite direction to disengage it from the positioning hole 802, thereby releasing the lock and allowing the synchronization frame 8 to move. This structure is easy to operate, provides a secure lock, and the multiple positioning holes 802 offer multiple adjustment options for the water collection plate assembly, further enhancing the flexibility of adapting to different working conditions.

[0031] In one optional embodiment, a support plate 3 is welded to the bottom opening of the ventilation port 2 of the tower body 1. A transmission assembly is provided on the bottom surface of the support plate 3. The transmission assembly includes an active transmission disk 401 and a driven transmission disk 6, which are used to drive the water collection plate assembly to swing back and forth. The active transmission disk 401 is rotatably connected to the bottom center of the support plate 3. Several impeller blades 4 are fixedly connected in a circular array at the top of the central shaft of the active transmission disk 401. The impeller blades 4 and the active transmission disk 401 are located on the upper and lower sides of the support plate 3, respectively. The driven transmission disk 6 is rotatably connected to the top of the inner side of the tower body 1. The driven transmission disk 6 and the active transmission disk 401 are connected to each other by a transmission belt 5.

[0032] In the above technical solution, the support plate 3 provides stable support for the transmission components. When the fan at the top of the tower 1 is running, it drives the airflow upward. When the airflow passes the bottom of the vent 2, it impacts the impeller 4, driving the impeller 4 to rotate the active transmission disc 401. The active transmission disc 401 transmits power to the driven transmission disc 6 through the transmission belt 5, realizing smooth power transmission and steering. This transmission structure requires no additional power source, relying entirely on the airflow of the cooling tower itself for drive. It is energy-saving, environmentally friendly, and reliable in operation, avoiding the problem of electrical drive components being prone to failure in humid and dusty outdoor environments.

[0033] It is worth noting that, such as Figure 2 and Figure 4 As shown, a drive disc 601 is fixedly connected to the bottom center of the active drive disc 401, and a drive rod 7 is fixedly connected to the top center of the synchronous frame 8. A push-pull rod 701 is provided between the drive rod 7 and the drive disc 601, with both ends of the push-pull rod 701 rotatably connected to the drive rod 7 and the drive disc 601, respectively. When the driven drive disc 6 rotates, it drives the bottom drive disc 601 to rotate synchronously. The drive disc 601 pulls the drive rod 7 to perform reciprocating linear motion through the eccentrically connected push-pull rod 701. The drive rod 7 then drives the synchronous frame 8 to move back and forth along the slide groove 903, which in turn drives the water collection plate assembly to swing back and forth through the crossbar 803 and the round rod 10, causing the angle and spacing of the water collection plate to change dynamically. This structure can break the stable gradient of the airflow in the water collection channel, increase the collision frequency and contact area between the airflow and the water collection plate, and more efficiently separate water droplets in the airflow, further improving the water collection efficiency. At the same time, the reciprocating swing can also reduce the adhesion and accumulation of scale and impurities on the surface of the water collection plate, reduce the risk of blockage, and reduce the maintenance burden.

[0034] It should be noted that the tower body 1 and the main frame 9 are installed in a detachable manner. The edge of the main frame 9 is fitted with the reserved mounting groove inside the ventilation opening 2 of the tower body 1, and is fixed by circumferentially distributed bolts. This ensures both installation stability and facilitates later overall disassembly and maintenance. (See attached diagram) Figure 1 The tower body 1 has a movable maintenance door on its side. After opening the maintenance door, the synchronous frame 8 on the front and rear surfaces of the main frame 9 can be directly accessed without disassembling the main frame 9. The operator can manually push the synchronous frame 8 along the slide 903 or rotate the positioning bolt 801 to lock it, which is convenient for adjusting the angle and spacing of the water collection plate assembly.

[0035] In addition to the aforementioned water collection components, the tower body 1 also features a recovery water tank at its bottom. A packing layer is laid horizontally above the tank, and a spray assembly is installed directly above the packing layer and below the water collection plate assembly. During operation, the circulating water in the recovery water tank is pumped to the spray assembly, which evenly sprays the water onto the surface of the packing layer. The water flow disperses within the packing layer, forming a thin water film that fully contacts and exchanges heat with the upward airflow drawn in by the fan at the top of the tower body 1. The airflow, carrying some water droplets, continues upward. When it passes the water collection plate assembly, the water droplets are intercepted and flow back along the plate to the packing layer or the recovery water tank. The dried airflow is then discharged through the vent 2, completing the entire workflow.

[0036] In addition, all components designed in this invention are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. They can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by this invention does not involve improvements to the internal structure and methods.
