Description

Technical Field

[0001] This utility model relates to the field of cooling water spraying technology, specifically a spraying device with an adjustable spraying area. Background Technology

[0002] In many fields of industrial production, such as chemical, power, and metallurgy, equipment cooling plays a crucial role in ensuring the stable operation of production systems, improving production efficiency, and ensuring product quality. Spraying devices, as one of the commonly used equipment in equipment cooling, spray cooling water onto the surface of high-temperature equipment and use the principle of water evaporation to absorb heat and remove the heat generated by the equipment, thereby achieving the cooling of the equipment.

[0003] However, most traditional spraying devices adopt a fixed spraying area design. During operation, spraying devices with a fixed spraying area cannot provide targeted cooling. Areas with low heat dissipation requirements will be over-cooled due to excessive cooling water, resulting in excessively low equipment surface temperature, causing changes in thermal stress of the equipment materials, and accelerating equipment aging. Areas with high heat dissipation requirements will be under-cooled due to insufficient cooling water, failing to effectively remove the heat generated by the equipment, thus affecting the performance and lifespan of the equipment.

[0004] Therefore, we propose a spraying device with an adjustable spraying area to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a spraying device with an adjustable spraying area, thus solving the problems mentioned in the background section.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A spraying device with adjustable spray area includes a water inlet pipe, a connecting pipe fixedly connected to the water inlet pipe, a nozzle fixedly connected to the lower end of the connecting pipe, a horizontal plate fixedly connected to the outer surface of the connecting pipe, and lifting columns symmetrically and slidably connected through the horizontal plate. Each lifting column has a connecting block fixedly connected to its lower end, and a diversion plate fixedly connected between two of the connecting blocks.

[0008] As a further embodiment of this utility model: each of the lifting columns is fixedly connected to a connecting plate at its upper end, and each connecting plate has a groove on the side near the connecting pipe. Each groove has a sliding column slidably connected to it, and each sliding column has a lever plate fixedly connected to the end away from the groove. A rotating shaft is fixedly connected between the two lever plates.

[0009] As a further embodiment of this utility model: a protective shell is fixedly connected to the outer surface of the connecting pipe, the rotating shaft is rotatably connected inside the protective shell, the protective shell and the connecting pipe are connected, and a water wheel is fixedly connected to the outer surface of the rotating shaft inside the protective shell, the water wheel being located between the connecting pipe and the protective shell.

[0010] As a further embodiment of this utility model: a drain hole is provided at the center of the drain plate, and a baffle is symmetrically and slidably connected to the upper surface of the drain plate, the baffle covering the drain hole.

[0011] As a further embodiment of this utility model: the upper surface of the baffle is symmetrically and rotatably connected with connecting rods, and the ends of the connecting rods on the same side away from the baffle are rotatably connected with pressing blocks. The lower end surface of the pressing blocks is fixedly connected with elastic telescopic columns, and the elastic telescopic columns are all fixedly connected to the upper surface of the diversion plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the water wheel, rotating shaft, deflector, sliding column, connecting plate, lifting column and connecting block, the guide plate can be driven to move up and down reciprocally during the cooling water spraying process. This changes the distance between the guide plate and the nozzle, thereby changing the splash area of ​​the cooling water sprayed on the guide plate. This allows the cooling water to cover the area that needs to be cooled more evenly, avoiding local over-cooling or under-cooling, thus improving the overall cooling effect and ensuring that the object or equipment being cooled can reach the ideal temperature state.

[0014] 2. Through the setting of pressing blocks, elastic telescopic columns, connecting rods and baffles, the baffles can be automatically pushed to open as the diversion plate approaches the nozzle, revealing the leakage holes opened on the diversion plate. This allows the cooling water sprayed by the nozzle to be discharged from the leakage holes and sprayed to the area directly below the diversion plate. This can accurately deliver the cooling water to the key parts that need cooling, avoiding the spraying of cooling water to areas that do not need cooling, and greatly improving the targeting of cooling.

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example:

[0023] like Figures 1-4 As shown, a spraying device with adjustable spray area includes a water inlet pipe 1, a connecting pipe 2 fixedly connected to the water inlet pipe 1, a nozzle 3 fixedly connected to the lower end of the connecting pipe 2, a horizontal plate 4 fixedly connected to the outer surface of the connecting pipe 2, lifting columns 7 symmetrically and slidably connected through the horizontal plate 4, a connecting block 6 fixedly connected to the lower end of each lifting column 7, and a diversion plate 5 fixedly connected between the two connecting blocks 6.

[0024] In this embodiment, as Figure 2 and Figure 3 As shown, each of the lifting columns 7 is fixedly connected to a connecting plate 8. Each connecting plate 8 has a groove 13 on the side near the connecting pipe 2. Each groove 13 has a sliding column 10 slidably connected to it. Each sliding column 10 is fixedly connected to a lever plate 11 at the end away from the groove 13. A rotating shaft 12 is fixedly connected between the two lever plates 11. When the rotating shaft 12 rotates, the lever plate 11 can drive the sliding column 10 to slide back and forth in the groove 13, so that the sliding column 10 can move the connecting plate 8 through the groove 13, thereby driving the lifting column 7 to slide up and down on the horizontal plate 4.

[0025] In this embodiment, as Figure 3 As shown, a protective shell 9 is fixedly connected to the outer surface of the connecting pipe 2. The rotating shaft 12 is rotatably connected inside the protective shell 9. The protective shell 9 and the connecting pipe 2 are connected. A water wheel 14 is fixedly connected to the outer surface of the rotating shaft 12 inside the protective shell 9. The water wheel 14 is located between the connecting pipe 2 and the protective shell 9. When cooling water passes through the connecting pipe 2, it will move one end of the water wheel 14, causing the water wheel 14 to drive the rotating shaft 12 to rotate on the protective shell 9.

[0026] In this embodiment, as Figure 4As shown, a drain hole 15 is provided at the center of the drain plate 5. A baffle 19 is symmetrically slidably connected to the upper end face of the drain plate 5. The baffle 19 covers the drain hole 15. When the baffle 19 separates from each other and opens the drain hole 15, the cooling water impacting the drain plate 5 will be sprayed out through the drain hole 15. When the baffle 19 covers the drain hole 15, the cooling water sprayed on the upper end face of the drain plate 5 will splash, increasing the spray area of ​​the cooling water.

[0027] In this embodiment, as Figure 4 As shown, each of the upper surfaces of the baffles 19 is symmetrically connected to a connecting rod 18. Each connecting rod 18 on the same side is rotatably connected to a pressing block 16 at the end away from the baffle 19. Each pressing block 16 is fixedly connected to an elastic telescopic column 17 at its lower surface. The elastic telescopic columns 17 are all fixedly connected to the upper surface of the diversion plate 5. When the pressing block 16 is subjected to force and descends, it will squeeze the elastic telescopic column 17 and push the two baffles 19 to slide and separate from each other through the connecting rod 18. When the pressing block 16 is subjected to force and disappears, the rebound force of the elastic telescopic column 17 can push the pressing block 16 to rise automatically, so that the pressing block 16 will pull the two baffles 19 to slide and approach each other again through the connecting rod 18.

[0028] The effects achieved by this embodiment are as follows: In the prior art, most traditional spraying devices adopt a fixed spraying area design. During operation, spraying devices with a fixed spraying area cannot provide targeted cooling. Areas with low heat dissipation requirements will be over-cooled due to excessive cooling water, resulting in excessively low surface temperatures of the equipment, causing changes in thermal stress of the equipment materials, and accelerating equipment aging. Areas with high heat dissipation requirements will be under-cooled due to insufficient cooling water, failing to effectively remove the heat generated by the equipment, affecting the performance and lifespan of the equipment. Compared with the prior art, during the cooling water spraying process, the guide plate 5 can be driven to move up and down reciprocally, changing the distance between the guide plate 5 and the nozzle 3. This changes the splashing area of ​​the cooling water sprayed on the guide plate 5, allowing the cooling water to cover the area that needs cooling more evenly, avoiding local over-cooling or under-cooling, thereby improving the overall cooling effect and ensuring that the cooled object or equipment can reach the ideal temperature state.

[0029] The overall working process and principles involved in the above embodiments are as follows:

[0030] When cooling water is sprayed from the nozzle 3 through the connecting pipe 2 via the inlet pipe 1, the cooling water inside the connecting pipe 2 will come into contact with one side of the water wheel 14, causing the water wheel 14 to rotate. This causes the rotating shaft 12 connected to the water wheel 14 to rotate synchronously on the protective shell 9. During the rotation of the rotating shaft 12, since both ends of the rotating shaft 12 are connected to the levers 11, and the side of the levers 11 away from the rotating shaft 12 is connected to the sliding column 10, the sliding column 10 is slidably connected in the groove 13 opened on the side wall of the connecting plate 8. The connecting plate 8 is fixedly connected to the lifting column 7. Therefore, as the rotating shaft 12 rotates, the rotating shaft 12 will drive the sliding column 10 to move in the groove 13 opened on the side wall of the connecting plate 8 through the levers 11. The sliding column 10 moves the connecting plate 8 through the groove 13, causing the lifting column 7 connected to the lower end of the connecting plate 8 to slide up and down synchronously on the horizontal plate 4. At this time, the lifting column 7 will drive the guide plate 5 to move up and down synchronously through the connecting block 6 connected to the lower end. During the spraying of cooling water by the nozzle 3, the distance between the guide plate 5 and the nozzle 3 is changed repeatedly, so that the cooling water impacts the guide plate 5 at different heights, thereby changing the spray area of ​​the cooling water. This allows the cooling water to cover the area that needs to be cooled more evenly, avoiding local over-cooling or under-cooling, thereby improving the overall cooling effect and ensuring that the object or equipment being cooled can reach the ideal temperature state.

[0031] As the guide plate 5 approaches the nozzle 3, the pressing block 16 above the guide plate 5 will preferentially contact the nozzle 3, and the pressing block 16 will be obstructed by the nozzle 3. As the guide plate 5 continues to rise, the pressing block 16 will gradually approach the guide plate 5 and push the elastic telescopic column 17 connected to the lower end of the pressing block 16 to retract. As the pressing block 16 approaches the guide plate 5, the pressing block 16 will drive the upper end of the connecting rod 18 connected to both sides to descend synchronously, causing the connecting rod 18 to move from an inclined position to a horizontal position. When the state changes, the connecting rod 18 will push the two side baffles 19 to slide and separate above the guide plate 5, opening the leakage hole 15 on the guide plate 5. At this time, the guide plate 5 will be in contact with the nozzle 3, and the cooling water sprayed by the nozzle 3 will be sprayed out from the leakage hole 15 on the guide plate 5, spraying the cooling water to the area below the guide plate 5. This changes the spray area of ​​the cooling water, which can accurately deliver the cooling water to the key parts that need cooling, avoiding the cooling water being sprayed to areas that do not need cooling, and greatly improving the targeting of cooling.
