Description

Technical Field

[0001] The utility model belongs to the technical field of central air conditioners, and more specifically, relates to a water distribution tray of a cooling tower. Background Art

[0002] The water distribution tray of a cooling tower is a key component in the cooling tower. Its function is to evenly distribute the hot water entering the cooling tower onto the packing or fins to increase the contact area between water and air, thereby improving the cooling efficiency.

[0003] During the use of the current water distribution tray of the cooling tower by staff, it is often found that: most of the shunt pipes on the current water distribution tray of the cooling tower are fixedly connected to the water distributor through a number of bolts. Since the water distribution tray is in a humid environment for a long time, the bolts are prone to rust under the long-term humid condition, resulting in a situation of reduced connection stability. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a water distribution tray of a cooling tower.

[0005] According to the first aspect embodiment of the utility model, there is provided a water distribution tray of a cooling tower, including a connecting column, a water distributor is rotatably connected to the connecting column, three installation pipes are fixedly connected to the water distributor, a shunt pipe is arranged on the installation pipe, a connecting structure is arranged on the shunt pipe, the connecting structure is mainly composed of a connecting pipe, the connecting pipe is fixedly connected to the shunt pipe, a sealing block is rotatably connected to the installation pipe, three sliding rods are slidably inserted into the installation pipe, three clamping grooves are formed on the connecting pipe, the sliding rods are adapted to the clamping grooves in size, and a sealing ring is fixedly connected to the installation pipe.

[0006] When installing the shunt pipe, insert the connecting pipe into the installation pipe so that the connecting pipe abuts against the sealing ring, and slide the three sliding rods to make them snap into the corresponding clamping grooves. Since the sliding rods are hermetically wrapped by the sealing block, they will not be corroded by the humid environment, and the service life can be improved, thus avoiding the situation that due to the long-term humid environment of the current water distribution tray, the bolts are prone to rust under the long-term humid condition, resulting in reduced connection stability.

[0007] According to the water distribution tray of the cooling tower described in the first aspect embodiment of the utility model, three adjusting blocks are fixedly connected to the sealing block, a first spring is sleeved on the sliding rod, one end of the first spring is fixedly connected to the installation pipe, and the other end of the first spring is fixedly connected to the sliding rod.

[0008] Rotating the sealing block counterclockwise can drive the three adjusting blocks to push the sliding rods, so that the three sliding rods are synchronously clamped into the corresponding card slots. At this time, the first spring is in a contracted state. Therefore, when the sealing block is rotated clockwise, the three sliding rods will slide out synchronously under the action of the elastic force of the first spring rebounding, which can make the installation and disassembly operations more convenient.

[0009] According to the water distribution tray of the cooling tower described in the first aspect embodiment of the present invention, a rectangular block is fixedly connected to the water distributor, an arc-shaped groove is provided on the rectangular block, and a round rod is slidably inserted into the sealing block. When the sealing block is rotated, the round rod is limited and slides in the arc-shaped groove.

[0010] According to the water distribution tray of the cooling tower described in the first aspect embodiment of the present invention, a round groove is provided in the arc-shaped groove, and the round groove is adapted to the size of the round rod. Rotating the sealing block counterclockwise to the leftmost end can clamp the round rod into the round groove to limit the sealing block, making the position of the sealing block more stable.

[0011] According to the water distribution tray of the cooling tower described in the first aspect embodiment of the present invention, a second spring is sleeved on the round rod. One end of the second spring is fixedly connected to the round rod, and the other end of the second spring is fixedly connected to the sealing block. When the round rod is clamped into the round groove, the second spring is in a contracted state. Therefore, the elastic force of the second spring rebounding acts on the round rod, making the connection between the round rod and the round groove more stable.

[0012] According to the water distribution tray of the cooling tower described in the first aspect embodiment of the present invention, a limiting structure is provided on the water distributor. The limiting structure is mainly composed of several fixing blocks. Several of the fixing blocks are fixedly connected to the water distributor. A rotating rod is rotatably connected between two of the fixing blocks. A pulling rope is fixedly connected to the rotating rod, and the pulling rope is fixedly connected to the shunt pipe. The pulling rope exerts a pulling force on the shunt pipe, which can make the position of the shunt pipe more stable.

[0013] According to the water distribution tray of the cooling tower described in the first aspect embodiment of the present invention, a disc is fixedly connected to one end of the rotating rod. Several limiting grooves are provided on the fixing block, and a limiting rod is slidably inserted into the disc. The limiting grooves are adapted to the size of the limiting rod. The disc can be rotated to drive the rotating rod to rotate, so that the length of the pulling rope is most suitable, preventing the pulling rope from loosening and reducing the pulling effect. After the position of the disc is determined, the limiting rod can be inserted into the corresponding limiting groove to limit the disc.

[0014] For the water distribution tray of the cooling tower according to the embodiment of the first aspect of the present utility model, a third spring is sleeved on the limiting rod. One end of the third spring is fixedly connected to the limiting rod, and the other end of the third spring is fixedly connected to the disc. When the limiting rod is inserted into the limiting groove, the third spring is in a stretched state. Therefore, the resilience of the third spring acts on the limiting rod, making the limiting more stable.

[0015] One of the technical solutions in the above technical solutions of the present utility model has at least one of the following advantages or beneficial effects:

[0016] In the water distribution tray of this cooling tower, by setting a connection structure, when installing the shunt pipe, insert the connecting pipe into the installation pipe so that the connecting pipe abuts against the sealing ring. Slide the three sliding rods so that they are inserted into the corresponding card slots. Since the sliding rods are sealed and wrapped by the sealing block, they will not be corroded by the humid environment, and the service life can be improved. Rotating the sealing block counterclockwise can drive the three adjusting blocks to push the sliding rods, so that the three sliding rods are synchronously inserted into the corresponding card slots. At this time, the first spring is in a contracted state. Therefore, when the sealing block is rotated clockwise, the three sliding rods will slide out synchronously under the action of the resilience of the first spring, which can make the installation and disassembly operations more convenient;

[0017] When rotating the sealing block, the round rod is limited and slides in the arc-shaped groove. Rotating the sealing block counterclockwise to the leftmost end can insert the round rod into the round groove to limit the sealing block, making the position of the sealing block more stable. When the round rod is inserted into the round groove, the second spring is in a contracted state. Therefore, the resilience of the second spring acts on the round rod, making the connection between the round rod and the round groove more stable, thus avoiding the situation that due to the long-term wet environment of the current water distribution tray, the bolts are easily corroded in the long-term wet condition, resulting in a reduction in connection stability.

[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present utility model.

[0029] Referring to Figures 1 to 4 As shown, a water distribution tray of a cooling tower is provided, which includes a connecting column 1, a water distributor 2 is rotatably connected to the connecting column 1, three mounting pipes 3 are fixedly connected to the water distributor 2, and a flow dividing pipe 4 is arranged on the mounting pipe 3.

[0030] Referring to Figure 2 and Figure 3, in some embodiments of the present utility model, a connection structure 5 is provided on the shunt pipe 4. The connection structure 5 is mainly composed of a connection pipe 51. The connection pipe 51 is fixedly connected to the shunt pipe 4. A sealing block 52 is rotatably connected to the installation pipe 3. Three sliding rods 53 are slidably inserted into the installation pipe 3. Three card slots 54 are provided on the connection pipe 51. The sliding rods 53 are adapted to the card slots 54 in size. A sealing ring 55 is fixedly connected to the installation pipe 3.

[0031] When installing the shunt pipe 4, insert the connection pipe 51 into the installation pipe 3 so that the connection pipe 51 abuts against the sealing ring 55. Slide the three sliding rods 53 to make them snap into the corresponding card slots 54. Since the sliding rods 53 are hermetically wrapped by the sealing block 52, they will not be corroded by the humid environment, which can improve the service life and thus avoid the situation that the connection stability is reduced due to the bolts being prone to rust in the long-term wet environment of the current water distribution tray.

[0032] Three adjusting blocks 56 are fixedly connected to the sealing block 52. A first spring 57 is sleeved on the sliding rod 53. One end of the first spring 57 is fixedly connected to the installation pipe 3, and the other end of the first spring 57 is fixedly connected to the sliding rod 53. Rotating the sealing block 52 counterclockwise can drive the three adjusting blocks 56 to push the sliding rods 53, so that the three sliding rods 53 synchronously snap into the corresponding card slots 54. And at this time, the first spring 57 is in a contracted state. Therefore, when the sealing block 52 is rotated clockwise, the three sliding rods 53 will synchronously slide outwards under the action of the elastic force of the first spring 57 rebounding, which can make the installation and disassembly operations more convenient.

[0033] , in some embodiments of the present utility model, a rectangular block 58 is fixedly connected to the water distributor 2. An arc-shaped groove 59 is provided on the rectangular block 58. A round rod 511 is slidably inserted into the sealing block 52. When the sealing block 52 is rotated, the round rod 511 is limited to slide in the arc-shaped groove 59. A round groove 512 is provided in the arc-shaped groove 59. The round groove 512 is adapted to the round rod 511 in size. Rotating the sealing block 52 counterclockwise to the leftmost end can snap the round rod 511 into the round groove 512 to limit the sealing block 52, making the position of the sealing block 52 more stable. A second spring 510 is sleeved on the round rod 511. One end of the second spring 510 is fixedly connected to the round rod 511, and the other end of the second spring 510 is fixedly connected to the sealing block 52. When the round rod 511 is snapped into the round groove 512, the second spring 510 is in a contracted state. Therefore, the elastic force of the second spring 510 rebounding acts on the round rod 511, making the connection between the round rod 511 and the round groove 512 more stable.

[0034] Refer to Figure 1 and Figure 4, in some embodiments of the present utility model, a limiting structure 6 is provided on the water distributor 2. The limiting structure 6 is mainly composed of a plurality of fixing blocks 61. The plurality of fixing blocks 61 are all fixedly connected to the water distributor 2. A rotating rod 62 is rotatably connected between two fixing blocks 61. A pulling rope 63 is fixedly connected to the rotating rod 62. The pulling rope 63 is fixedly connected to the shunt pipe 4. The pulling rope 63 applies a pulling force to the shunt pipe 4, which can make the position of the shunt pipe 4 more stable. One end of the rotating rod 62 is fixedly connected to a disc 64. A plurality of limiting grooves 65 are formed in the fixing block 61. A limiting rod 66 is slidably inserted into the disc 64. The limiting groove 65 and the limiting rod 66 are of suitable sizes.

[0035] The rotatable disc 64 drives the rotating rod 62 to rotate, so that the length of the pulling rope 63 is most suitable, preventing the pulling rope 63 from loosening and reducing the pulling effect. After the position of the disc 64 is determined, the limiting rod 66 can be inserted into the corresponding limiting groove 65 to limit the disc 64. A third spring 67 is sleeved on the limiting rod 66. One end of the third spring 67 is fixedly connected to the limiting rod 66, and the other end of the third spring 67 is fixedly connected to the disc 64. When the limiting rod 66 is snapped into the limiting groove 65, the third spring 67 is in a stretched state. Therefore, the resilient force of the third spring 67 acts on the limiting rod 66, making the limiting more stable.

[0036] When installing the shunt pipe 4, the connecting pipe 51 is inserted into the installation pipe 3 so that the connecting pipe 51 abuts against the sealing ring 55. The three sliding rods 53 are slid to make them snap into the corresponding card slots 54. Since the sliding rods 53 are hermetically wrapped by the sealing blocks 52, they will not be corroded by the humid environment, and the service life can be improved, thus avoiding the situation that the connection stability is reduced due to the bolts being prone to rust in the long-term humid environment of the current water distribution tray.

[0037] Rotating the sealing block 52 counterclockwise can drive the three adjusting blocks 56 to push the sliding rods 53, so that the three sliding rods 53 are synchronously clamped into the corresponding card slots 54. At this time, the first spring 57 is in a contracted state. Therefore, when the sealing block 52 is rotated clockwise, the three sliding rods 53 will slide out synchronously under the action of the elastic force of the first spring 57 rebounding, which can make the installation and disassembly operations more convenient. When the sealing block 52 is rotated, the round rod 511 slides in the arc-shaped groove 59 in a limited manner. Rotating the sealing block 52 counterclockwise to the leftmost end can clamp the round rod 511 into the round groove 512 to limit the sealing block 52, making the position of the sealing block 52 more stable. When the round rod 511 is clamped into the round groove 512, the second spring 510 is in a contracted state. Therefore, the elastic force of the second spring 510 rebounding acts on the round rod 511, making the connection between the round rod 511 and the round groove 512 more stable. The pull rope 63 applies a pulling force to the shunt pipe 4, which can make the position of the shunt pipe 4 more stable. The rotating disc 64 can be rotated to drive the rotating rod 62 to rotate, so that the length of the pull rope 63 is most suitable to prevent the pull rope 63 from loosening and reducing the pulling effect. After the position of the disc 64 is determined, the limiting rod 66 can be inserted into the corresponding limiting groove 65 to limit the disc 64. When the limiting rod 66 is clamped into the limiting groove 65, the third spring 67 is in a stretched state. Therefore, the elastic force of the third spring 67 rebounding acts on the limiting rod 66, making the limiting more stable.
