Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a water-blocking device for a mechanical ventilation cooling tower. Background Technology

[0002] Mechanical ventilation cooling towers are devices that use fans to force airflow, allowing hot circulating water to come into contact with cold air inside the tower. Through mass and heat transfer processes, the heat in the water is removed, thus achieving the purpose of cooling. They are widely used in various applications requiring large amounts of heat dissipation. The water baffle device inside the mechanical ventilation cooling tower is an important component. Its main purpose is to prevent water vapor or water droplets from splashing, avoiding pollution to the surrounding environment and losses caused by cooling water being carried into the air. At the same time, it also ensures the safety of equipment and personnel.

[0003] A search revealed an existing patent (publication number: CN219736114U) that discloses a water baffle for a cooling tower, comprising a cooling tower and a water baffle. The cooling tower has an internal ring containing multiple partitions. One end of each partition is connected together, and the other end is mounted on the inner wall of the ring. The ring is divided into multiple mounting cavities by the partitions. The outer surface of the ring has multiple mounting ports communicating with the mounting cavities. The water baffle consists of multiple sets of baffle plates, each with an outer frame that passes through the mounting ports and is inserted into the mounting cavities. This invention has a simple structure; the ring can rotate the cooling plates, allowing each plate to be aligned with the inlet and outlet. Cooling plates can be directly removed or installed through the inlet and outlet, increasing the convenience of installation and disassembly and ensuring the normal operation of the cooling tower.

[0004] However, in the above solution, the cover plate is locked with bolts, which means that each time the cooling plate is disassembled and maintained, tools such as screwdrivers must be used to disassemble and install the cover plate, making disassembly and assembly cumbersome and inconvenient. Furthermore, after the cover plate is opened, the space it opens is limited, making it inconvenient to pull out or slide in the cooling plate, which in turn increases the difficulty of pulling out and installing the cooling plate to a certain extent, resulting in inconvenience in its use.

[0005] In view of this, the present invention proposes a water-blocking device for a mechanical ventilation cooling tower. Summary of the Invention

[0006] This utility model proposes a water-blocking device for mechanical ventilation cooling towers, which solves the problem of inconvenient and quick disassembly and assembly of cooling plates in related technologies.

[0007] The technical solution of this utility model is as follows: A water-blocking device for a mechanical ventilation cooling tower includes a tower body; a support platform fixedly connected to the upper end of the inner wall of the tower body, the top of the support platform having a circumferential groove, and a slider movably connected inside the groove; a rotating frame fixedly connected to the top of the slider; symmetrically formed limiting grooves on the inner wall of the rotating frame, water-blocking frames arranged at equal angles inside the rotating frame, limiting strips fixedly connected to both sides of the water-blocking frames, water-blocking plates fixedly connected at equal intervals to the inner wall of the water-blocking frames, and a handle fixedly connected to one side of the water-blocking frames; a fixed...

[0008] A slot is provided, and a cover plate is engaged on one side of the tower body; an installation assembly is assembled on one side of the tower body, which is used to enable quick engagement and disengagement between the cover plate and the tower body.

[0009] The mounting assembly includes: mounting grooves symmetrically formed on one side of the tower body surface, with a sliding rod fixedly connected to the inner wall of the mounting groove; a sliding block slidably connected to the surface of the sliding rod, with a mounting block fixedly connected to one end of the top of the sliding block; a mounting spring wound around the surface of the sliding rod, with both ends of the mounting spring fixedly connected to the bottom wall of the mounting groove and the bottom end of the sliding block, respectively; a connecting rod fixedly connected between the two sliding blocks; and mounting holes symmetrically formed at the bottom end of the cover plate.

[0010] Preferably, the top of the mounting block and the interior of the mounting hole form an engaging structure, and the mounting block and the mounting hole are symmetrically distributed about the vertical central axis of the cover plate.

[0011] Preferably, a sealing sleeve is fixedly connected to one side of the cover plate surface, and the area of ​​the cross-section of the sealing sleeve is equal to the area of ​​the cross-section of the opening inside the fixing groove.

[0012] Preferably, the cross-sectional shape of the baffle plate is S-shaped, and the two ends of the baffle plate are welded to the inner wall of the baffle frame in an integrated structure.

[0013] Preferably, the inner wall of the support platform is in the shape of an inverted frustum, and the top of the sliding groove is in the same horizontal plane as the bottom wall of the fixed groove.

[0014] Preferably, an auxiliary groove is provided in a ring on the inner wall of the tower body above the water-blocking frame, and the height of the auxiliary groove is greater than the height of the handle.

[0015] Preferably, the slider and the interior of the groove form a sliding structure, the cross-sectional shape of the groove and the slider is convex, and the top of the support platform is provided with slots that penetrate the groove at equal intervals.

[0016] Preferably, the limiting strip and the interior of the limiting groove form a sliding structure, and the limiting strip and the limiting groove are in the shape of an isosceles trapezoid.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model utilizes an installation component to achieve quick disassembly and assembly of the cover plate, avoiding the cumbersome and inconvenient disassembly and assembly caused by the traditional use of bolts. At the same time, the use of a handle makes it easy for users to slide the water-blocking frame between the rotating frames. An auxiliary groove is also provided so that the rotation of the rotating frame is not obstructed by the rotation of the handle. This avoids the inconvenience caused by the internal space limitation of the traditional fixed groove, which makes it difficult for users to pinch and pull the water-blocking frame. This makes it easier and more convenient to pull the water-blocking frame and improves the efficiency of disassembly and replacement.

[0019] 2. In this utility model, the sliding of the convex slider and the inside of the groove allows the rotating frame to rotate on the top of the support platform without detaching from it. When the rotating frame needs to be disassembled and maintained, it can be rotated so that when the slider rotates to the groove, the rotating frame can be slid off the support platform. This facilitates the disassembly and maintenance of the rotating frame and avoids the inconvenience of disassembly and assembly of traditional rotating frames, which leads to subsequent maintenance or replacement, thus improving its practicality.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] A preferred embodiment of the water-blocking device for a mechanical ventilation cooling tower provided by this utility model is shown in Figures 1 to 12. Figure 6 As shown: A water-blocking device for a mechanical ventilation cooling tower includes a tower body 1; a support platform 8 fixedly connected to the upper end of the inner wall of the tower body 1, with a sliding groove 7 annularly opened at the top of the support platform 8, and a slider 11 movably connected inside the sliding groove 7; a rotating frame 3 fixedly connected to the top of the slider 11; limiting grooves 15 symmetrically opened on the inner wall of the rotating frame 3, with water-blocking frames 12 arranged at equal angles inside the rotating frame 3, limiting strips 14 fixedly connected to both sides of the water-blocking frame 12, water-blocking plates 6 fixedly connected at equal intervals on the inner wall of the water-blocking frame 12, and a handle 13 fixedly connected to one side of the water-blocking frame 12; a fixing groove 10 opened at the upper end of one side of the tower body 1, with a cover plate 5 engaged on one side of the tower body 1; and an installation assembly 4 assembled on one side of the tower body 1, which is used to realize quick engagement and disengagement between the cover plate 5 and the tower body 1.

[0030] The mounting assembly 4 includes: mounting grooves 402 symmetrically formed on one side of the surface of the tower body 1, with a sliding rod 404 fixedly connected to the inner wall of the mounting groove 402; a sliding block 405 slidably connected to the surface of the sliding rod 404, with a mounting block 401 fixedly connected to one end of the top of the sliding block 405; a mounting spring 403 wound around the surface of the sliding rod 404, with both ends of the mounting spring 403 fixedly connected to the bottom wall of the mounting groove 402 and the bottom end of the sliding block 405, respectively; a connecting rod 406 fixedly connected between the two sliding blocks 405; and mounting holes 407 symmetrically formed at the bottom of the cover plate 5.

[0031] In this embodiment, by moving the connecting rod 406, the two sliding blocks 405 are driven to slide down, thereby causing the mounting block 401 to slide down until it is completely disengaged from the mounting hole 407. Then the cover plate 5 can be removed from the fixing groove 10. During installation, the elastic force of the mounting spring 403 can be used to make the sliding block 405 slide up and drive the mounting block 401 to lock into the mounting hole 407, so as to achieve a firm and stable engagement between the cover plate 5 and the fixing groove 10.

[0032] In a further preferred embodiment of the present invention, the top of the mounting block 401 and the interior of the mounting hole 407 form an engaging structure, and the mounting block 401 and the mounting hole 407 are symmetrically distributed about the vertical central axis of the cover plate 5.

[0033] In this embodiment, the quick engagement and disassembly of the cover plate 5 and the tower body 1 is achieved by utilizing the engagement between the mounting block 401 and the mounting hole 407.

[0034] In a further preferred embodiment of the present invention, a sealing sleeve 16 is fixedly connected to one side of the surface of the cover plate 5, and the area of ​​the cross-section of the sealing sleeve 16 is equal to the area of ​​the cross-section of the opening inside the fixing groove 10.

[0035] In this embodiment, the sealing sleeve 16 is used to improve the sealing performance of the cover plate 5 and the internal engagement of the fixing groove 10.

[0036] In a further preferred embodiment of this utility model, the cross-sectional shape of the water baffle 6 is S-shaped, and the two ends of the water baffle 6 are welded together with the inner wall of the water baffle frame 12.

[0037] In this embodiment, an S-shaped baffle 6 is used to avoid splashing of water vapor or water droplets, thereby reducing the loss of cooling water.

[0038] In a further preferred embodiment of this utility model, the inner wall of the support platform 8 is inverted frustum shape, and the top of the sliding groove 7 is connected to the fixing groove.

[0039] 10. The inner bottom walls are in the same horizontal plane.

[0040] In this embodiment, the frustum-shaped support platform 8 is used to facilitate water blocking between the rotating frame 3 and the inner wall of the tower body 1.

[0041] In a further preferred embodiment of this utility model, an auxiliary groove 2 is provided in an annular shape on the inner wall of the tower body 1 above the water-blocking frame 12, and the height inside the auxiliary groove 2 is greater than the height of the handle 13.

[0042] In this embodiment, the auxiliary groove 2 is used so that when the rotating frame 3 rotates, the handle 13 can rotate inside the auxiliary groove 2, thus avoiding obstruction when the rotating frame 3 rotates.

[0043] In a further preferred embodiment of the present invention, a sliding structure is formed between the slider 11 and the interior of the groove 7. The cross-sectional shape of the groove 7 and the slider 11 is convex. The top of the support platform 8 is provided with notches 9 that penetrate the groove 7 at equal intervals.

[0044] In this embodiment, the sliding of the convex slider 11 with the inside of the groove 7 allows the rotating frame 3 to rotate on the top of the support platform 8 without detaching from the top of the support platform 8. Furthermore, a notch 9 is provided so that when the slider 11 rotates to the notch 9, the rotating frame 3 can be slid off the support platform 8, facilitating the disassembly and maintenance of the rotating frame 3.

[0045] In a further preferred embodiment of the present invention, a sliding structure is formed between the interior of the limiting strip 14 and the limiting groove 15, and the shapes of the limiting strip 14 and the limiting groove 15 are isosceles trapezoids.

[0046] In this embodiment, the stability of the initial sliding installation between the water-blocking frame 12 and the inner wall of the rotating frame 3 is improved by utilizing the sliding between the isosceles trapezoidal limiting strip 14 and the limiting groove 15.

[0047] The working principle of this utility model is as follows: First, by moving the connecting rod 406, the two sliding blocks 405 slide down to compress the mounting spring 403, which in turn causes the mounting block 401 to slide down until it is completely disengaged from the mounting hole 407. Then, the cover plate 5 can be removed from the fixing groove 10. Next, the rotating frame 3 is rotated so that one of the water-blocking frames 12 is completely in the fixing groove 10. Then, the handle 13 is used to slide one of the water-blocking frames 12 out through the fixing groove 10, which facilitates the cleaning and maintenance of the water-blocking plate 6 at this location. Then, the rotating frame 3 is rotated in sequence to facilitate the sliding removal of the other water-blocking frames 12. During installation, the limiting strip 14 and the limiting groove 15 are used to...

[0048] The sliding mechanism slides the water-blocking frame 12 into the rotating frame 3. At the same time, the connecting rod 406 drives the mounting block 401 to descend, and then the cover plate 5 is locked into the fixing groove 10. One end of the cover plate 5 is attached to one of the handles 13, which hinders the rotation of the rotating frame 3 and improves the limiting stability of the rotating frame 3 and the water-blocking frame 12. At the same time, the elastic force of the mounting spring 403 is used to make the sliding block 405 slide upward and drive the mounting block 401 to lock into the mounting hole 407, so as to achieve a firm and stable engagement between the cover plate 5 and the fixing groove 10.

[0049] Simultaneously, by utilizing the sliding of the convex slider 11 and the inside of the groove 7, the rotating frame 3 can rotate on the top of the support platform 8 without detaching from the top of the support platform 8. Furthermore, when it is necessary to disassemble and maintain the rotating frame 3, the rotating frame 3 can be rotated so that when the slider 11 rotates to the notch 9, the rotating frame 3 can be slid off the support platform 8, facilitating the disassembly and maintenance of the rotating frame 3.

[0050] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
