Description

Technical Field

[0001] This utility model relates to the field of refrigeration pipeline technology, specifically a circulating refrigeration pipeline structure for a refrigeration room. Background Technology

[0002] In refrigeration rooms, circulating refrigeration pipes are key components for transporting cryogenic refrigerants. Because the refrigerant flowing inside these pipes is at a temperature far below ambient temperature, the outer walls of the pipes come into contact with water vapor in the air, causing condensation and producing a large amount of water. This condensate adheres to the pipe walls and drips down, not only causing dampness on the room floor and posing safety hazards, but also potentially leading to bacterial growth, corrosion of the pipe insulation, and damage to the equipment beneath, ultimately affecting the room environment and the lifespan of the equipment.

[0003] Currently, common solutions involve laying absorbent material under the pipes or installing simple drip trays. However, absorbent material requires frequent replacement, increasing maintenance workload; and traditional drip trays are mostly fixed structures, inconvenient to install, and cannot accommodate pipes of different diameters. More importantly, after long-term use, scale and impurities easily accumulate inside the drip tray. If not cleaned promptly, this can clog the drain holes, causing the drip tray to malfunction, resulting in overflowing water, and the problem persists. Therefore, we propose a new circulating refrigeration pipe structure for chiller rooms. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a circulating refrigeration pipe structure for a chiller room, which solves the problem that after long-term use, scale and impurities easily accumulate inside the water tray, which can clog the drain hole if not cleaned in time, leading to the failure of the water tray and water overflow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A circulating refrigeration pipeline structure for a refrigeration room includes a refrigeration pipeline body, a connecting mechanism detachably connected to the outside of the refrigeration pipeline body, a water collection mechanism detachably connected inside the connecting mechanism, and a cleaning mechanism provided inside the water collection mechanism.

[0006] The water collection mechanism includes a guide plate, a threaded sleeve, a threaded rod, a connecting pipe, a connecting hole, an F-type connecting rod, a fixing hole, and a water collection box. One side of the F-type connecting rod has a connecting hole penetrating its surface. The bottom of the F-type connecting rod is fixedly connected to the water collection box. Guide plates are rotatably connected to both sides of the water collection box. One end of the guide plate is rotatably connected to a threaded rod. Two sets of threaded rods are provided, and the two sets of threaded rods are threadedly connected by a threaded sleeve. The bottom of the water collection box has a connecting hole, and the bottom of the connecting hole is fixedly connected to a connecting pipe. The cleaning mechanism includes a bidirectional lead screw, a scraper, a connecting frame, a slide rod, a drive motor, and a motor housing. The inside of the water collection box is rotatably connected to the bidirectional lead screw. The outer ends of both ends of the bidirectional lead screw are threadedly connected to the connecting frame, and the bottom of the connecting frame is fixedly connected to the scraper.

[0007] In a preferred embodiment, a motor housing is fixedly connected to one side of the water collection box, a drive motor is fixedly connected inside the motor housing, one end of the bidirectional lead screw is fixedly connected to the output end of the drive motor, and sliding rods are symmetrically fixedly connected inside the water collection box, with the outer side of the sliding rods slidably connected to the connecting frame.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: When condensate drips from the outer wall of the refrigeration pipe body, it is guided by the opened guide plate and falls accurately into the water collection box below. The collected condensate is drained away through the bottom connection hole and connecting pipe. By rotating the threaded sleeve, the two sets of threaded rods can be extended or retracted synchronously, thereby driving the guide plate to rotate around its connection point with the water collection box, realizing the adjustment of the water receiving angle to adapt to pipes of different diameters or different installation environments. When there are deposits or scale at the bottom of the water collection box, the drive motor is started through the control panel. The drive motor drives the bidirectional screw to rotate. The two connecting brackets threaded to the bidirectional screw, guided by the slide rod, move the U-shaped scraper in opposite directions. The rubber scraper head on the scraper scrapes away the dirt at the bottom and inner wall of the water collection box and pushes it near the drain hole, where it is discharged with the water flow, preventing blockage and keeping the water collection box clean.

[0009] In a preferred embodiment, the connecting mechanism includes a U-shaped frame, a connecting plate, bolts, and connecting grooves. Connecting grooves are provided on both sides of the U-shaped frame, and a connecting plate is detachably connected to the top of the U-shaped frame. The connecting plate is detachably connected to the U-shaped frame by bolts.

[0010] The technical effect of adopting the above-mentioned further solution is as follows: the U-shaped frame is fitted on the outside of the main body of the refrigeration pipe, and the connecting plate is passed through both ends of the U-shaped frame, so that the threaded holes on both sides of the connecting plate coincide with the threaded holes on both sides of the U-shaped frame and the fixing holes on the surface of the F-type connecting rod. The U-shaped frame and the water collection box are fixed to the outside of the main body of the refrigeration pipe by bolts.

[0011] In a preferred embodiment, the outer side of the F-type connecting rod is slidably connected to the connecting groove, and a limit block is fixedly connected to one side of the F-type connecting rod.

[0012] The technical effect of adopting the above-mentioned further solution is that the F-type connecting rod moves inside the connecting groove, and the F-type connecting rod moves with the limiting block, which restricts the range of movement of the F-type connecting rod in the connecting groove.

[0013] In one preferred embodiment, one end of the set of threaded rods is rotatably connected to the U-shaped frame.

[0014] The technical advantage of adopting the above-mentioned further solution is that it can better fix the angle of the guide vane after adjustment.

[0015] In a preferred embodiment, the scraper is U-shaped, and rubber scraper heads are provided at the bottom and on both sides of the scraper.

[0016] The technical effect of adopting the above-mentioned further solution is that the bottom of the rubber scraper head fits against the inner wall of the water collection box, and the connecting frame, along with the rubber scraper head, cleans the inner wall of the water collection box.

[0017] In a preferred embodiment, a control panel is provided on one side of the main body of the refrigeration pipe, and the drive motor is electrically connected to the control panel.

[0018] The technical advantage of adopting the above-mentioned further solution is that the drive motor can be controlled through the control panel, thereby enabling better control of the entire device.

[0019] This utility model provides a circulating refrigeration pipe structure for a chiller room. Compared with the prior art, it has the following advantages: Through the design of the connecting mechanism and the sliding F-type connecting rod, this device can be easily installed on refrigeration pipes of different diameters. The angle of the guide plate is adjustable, ensuring that an effective water receiving surface can be formed for various installation positions, making it highly versatile. The combination design of the water collection box and the guide plate can efficiently collect condensate dripping from all directions of the pipe and discharge it in an orderly manner through the connecting pipe, effectively avoiding dampness and water accumulation on the floor of the chiller room and the resulting safety hazards and equipment corrosion problems. The built-in cleaning mechanism can be driven by a motor to automatically scrape and clean the inside of the water collection box periodically or as needed, effectively preventing scale and impurities from clogging the drain hole. This greatly reduces the frequency of manual cleaning and maintenance workload, ensuring the long-term effectiveness of the water collection function. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: A circulating refrigeration pipeline structure for a chiller room includes a refrigeration pipeline body 1. A connecting mechanism 3 is detachably connected to the outside of the refrigeration pipeline body 1. A water collection mechanism 2 is detachably connected inside the connecting mechanism 3. A cleaning mechanism 4 is provided inside the water collection mechanism 2. The water collection mechanism 2 includes a guide plate 21, a threaded sleeve 22, a threaded rod 23, a connecting pipe 24, a connecting hole 25, an F-type connecting rod 26, a fixing hole 27, and a water collection box 28. A connecting hole 25 penetrating through the surface of the F-type connecting rod 26 is opened on one side. The water collection box 28 is fixedly connected to the bottom of the F-type connecting rod 26. The guide plate 21 is rotatably connected to both sides of the water collection box 28. A threaded rod 23 is rotatably connected to one end of the guide plate 21. There are two sets of threaded rods 23, and the two sets of threaded rods 23 are connected by a threaded sleeve. 22. A threaded connection is provided. The bottom of the water collection box 28 is provided with a connection hole 25. A connection pipe 24 is fixedly connected to the bottom of the connection hole 25. The cleaning mechanism 4 includes a bidirectional lead screw 41, a scraper 42, a connecting frame 43, a slide rod 44, a drive motor 45, and a motor housing 46. The bidirectional lead screw 41 is rotatably connected inside the water collection box 28. The two ends of the bidirectional lead screw 41 are threadedly connected to the outer side of the connecting frame 43. The bottom of the connecting frame 43 is fixedly connected to the scraper 42. The motor housing 46 is fixedly connected to one side of the water collection box 28. The drive motor 45 is fixedly connected inside the motor housing 46. One end of the bidirectional lead screw 41 is fixedly connected to the output end of the drive motor 45. The slide rod 44 is symmetrically fixedly connected inside the water collection box 28. The outer side of the slide rod 44 is slidably connected to the connecting frame 43.

[0024] In this design, the guide plates 21 on both sides of the water collection box 28 can be angled according to actual conditions. When the threaded sleeve 22 is rotated, due to the transmission characteristics of the thread, the threaded rods 23 at both ends will move in opposite directions simultaneously, thereby driving the guide plates 21 to rotate around the connection point with the water collection box 28. In this way, the operator can precisely adjust the angle of the guide plates 21 according to the flow direction and speed of the condensate on the surface of the refrigeration pipe body 1, so that the condensate can be guided to flow into the water collection box 28 along the surface of the guide plates 21 to the maximum extent. For example, if it is found that there is more condensate on one side of the refrigeration pipe body 1 and the flow direction is more concentrated, the angle of the guide plates 21 on that side can be tilted more by adjusting the threaded sleeve 22. To better collect and guide condensate, and to ensure that the water collection box 28 can continuously and effectively collect condensate, the cleaning mechanism 4 starts working. When the operator starts the drive motor 45 through the control panel 11, the output shaft of the drive motor 45 will drive the bidirectional lead screw 41 to rotate at high speed. Since the two ends of the bidirectional lead screw 41 are respectively machined with threads of opposite directions, and these two ends are respectively threaded to the connecting frame 43, when the bidirectional lead screw 41 rotates, the connecting frames 43 at both ends will move in relative or opposite directions along the axial direction of the bidirectional lead screw 41 under the action of the threads. The bottom of the connecting frame 43 is fixedly connected to the scraper 42. When the connecting frame 43 moves, the scraper 42 will also scrape back and forth at the bottom of the water collection box 28.

[0025] like Figure 2 and Figure 4 As shown: In this solution, the connecting mechanism 3 includes a U-shaped frame 31, a connecting plate 32, bolts 33 and connecting grooves 34. Connecting grooves 34 are provided on both sides of the U-shaped frame 31, and the connecting plate 32 is detachably connected to the top of the U-shaped frame 31. The connecting plate 32 is detachably connected to the U-shaped frame 31 by bolts 33.

[0026] In this scheme, the workers accurately fit the U-shaped frame 31 onto the outside of the refrigeration pipe body 1, ensuring that both sides of the U-shaped frame 31 fit tightly against the pipe. Then, the F-type connecting rod 26 is inserted into the connecting grooves 34 on both sides of the U-shaped frame 31. The F-type connecting rod 26 slides smoothly in the connecting grooves 34. After adjusting the position, the connecting plate 32 is passed through both ends of the U-shaped frame 31, ensuring that the threaded holes on both sides of the connecting plate 32 completely overlap with the threaded holes on both sides of the U-shaped frame 31 and the fixing holes 27 on the surface of the F-type connecting rod 26. Finally, by tightening the bolts 33, the U-shaped frame 31 and the water collection box 28 are firmly fixed to the refrigeration pipe body 1, completing the initial installation of the connecting mechanism 3 and the water collection mechanism 2.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown: In this scheme, the outer side of the F-type connecting rod 26 is slidably connected to the connecting groove 34, a limit block is fixedly connected to one side of the F-type connecting rod 26, one end of a set of threaded rods 23 is rotatably connected to the U-shaped frame 31, the scraper 42 is U-shaped, and rubber scraper heads are provided on the bottom and both sides of the scraper 42. A control panel 11 is provided on one side of the refrigeration pipe body 1, and the drive motor 45 is electrically connected to the control panel 11.

[0028] In this design, the F-type connecting rod 26 slides smoothly within the connecting groove 34 to adjust the height of the water collection box 28. After adjusting the position, the connecting plate 32 is passed through both ends of the U-shaped frame 31, ensuring that the threaded holes on both sides of the connecting plate 32 completely overlap with the threaded holes on both sides of the U-shaped frame 31 and the fixing holes 27 on the surface of the F-type connecting rod 26. Finally, by tightening the bolts 33, the U-shaped frame 31 and the water collection box 28 are firmly fixed to the refrigeration pipe body 1, completing the initial installation of the connecting mechanism 3 and the water collection mechanism 2. When the operator starts the drive motor 45 through the control panel 11, the output shaft of the drive motor 45 will drive the bidirectional... The lead screw 41 rotates at high speed. When the bidirectional lead screw 41 moves the connecting frame 43, the scraper 42 will also scrape back and forth at the bottom of the water collection box 28. The rubber scraper head at the bottom and on both sides of the scraper 42 has good flexibility and conformity, and can closely fit the inner wall of the water collection box 28, quickly scraping the water at the bottom towards the connecting hole 25, so that the water can quickly flow into the connecting pipe 24 through the connecting hole 25 and finally be discharged to the designated location. At the same time, the rubber scraper head can also effectively scrape away the soft scale that gradually accumulates on the surface of the water collection box 28 during the scraping process, keeping the inside of the water collection box 28 clean and ensuring smooth drainage.

[0029] Working principle: In use, the main body 1 of the refrigeration pipe plays a crucial role in the entire system, delivering cooling. When chilled water is output from the compressor, it flows along the main body 1. Because the temperature of the chilled water is significantly lower than the ambient temperature around the pipe, condensation occurs on the outer wall of the pipe. In this refrigeration pipe system, a large amount of water vapor liquefies on the outer wall of the main body 1, forming condensate, which gradually gathers into droplets and slides down the outer wall of the pipe. The operator accurately places the U-shaped frame 31 onto the outside of the main body 1, ensuring a tight fit between the two sides of the U-shaped frame 31 and the pipe. Then, the F-shaped connecting rod 26 is inserted into the connecting grooves 34 on both sides of the U-shaped frame 31. The F-shaped connecting rod 26 slides smoothly within the connecting grooves 34. After adjusting the position, the connecting plate is... 32 passes through both ends of the U-shaped frame 31, ensuring that the threaded holes on both sides of the connecting plate 32 are completely aligned with the threaded holes on both sides of the U-shaped frame 31 and the fixing holes 27 on the surface of the F-type connecting rod 26. Finally, by tightening the bolts 33, the U-shaped frame 31 and the water collection box 28 are firmly fixed to the refrigeration pipe body 1, completing the initial installation of the connecting mechanism 3 and the water collection mechanism 2. The water collection mechanism 2 then plays a crucial role in effectively collecting the condensate that has fallen. The F-type connecting rod 26 is detachably connected to the U-shaped frame 31 in the connecting mechanism 3 through the connecting groove 34, ensuring that the water collection box 28 can be stably positioned below the refrigeration pipe body 1. The guide plates 21 on both sides of the water collection box 28 can be adjusted in angle according to the actual situation. When rotating the threaded sleeve 22, Due to the transmission characteristics of the threads, the threaded rods 23 at both ends will move in opposite directions simultaneously, thereby driving the guide plate 21 to rotate around the connection point with the water collection box 28. In this way, the operator can precisely adjust the angle of the guide plate 21 according to the flow direction and speed of the condensate on the surface of the refrigeration pipe body 1, so that it can guide the condensate along the surface of the guide plate 21 into the water collection box 28 to the maximum extent. For example, if it is found that there is more condensate on one side of the refrigeration pipe body 1 and the flow direction is more concentrated, the angle of the guide plate 21 on that side can be tilted more by adjusting the threaded sleeve 22 to better receive and guide the condensate. In order to ensure that the water collection box 28 can continuously and effectively collect condensate, the cleaning mechanism 4 starts to work. When the operator passes through After the control panel 11 starts the drive motor 45, the output shaft of the drive motor 45 will drive the bidirectional lead screw 41 to rotate at high speed. Since the two ends of the bidirectional lead screw 41 are respectively machined with threads of opposite directions, and these two ends are respectively threaded to the connecting frame 43, when the bidirectional lead screw 41 rotates, the connecting frames 43 at both ends will move in opposite or opposite directions along the axial direction of the bidirectional lead screw 41 under the action of the threads. The bottom of the connecting frame 43 is fixedly connected to the scraper 42. When the connecting frame 43 moves, the scraper 42 will also scrape back and forth at the bottom of the water collection box 28. The rubber scraper heads on the bottom and sides of the scraper 42 have good flexibility and conformity, and can closely conform to the inner wall of the water collection box 28, quickly scraping the water at the bottom towards the connecting hole 25.This allows accumulated water to quickly flow through the connection hole 25 into the connection pipe 24 and ultimately be discharged to the designated location. Simultaneously, the rubber scraper effectively removes softer scale that gradually accumulates on the surface of the water collection box 28, keeping the inside of the box clean and ensuring smooth drainage. Throughout the operation, the connection mechanism 3 provides a stable mounting base for the water collection mechanism 2 and the cleaning mechanism 4, ensuring they are accurately positioned below the main body of the refrigeration pipe 1, effectively collecting and treating condensate. The close cooperation between these mechanisms forms a highly efficient condensate management system, solving the problem of difficult condensate treatment in traditional refrigeration pipes and improving the safety of the chiller room and the operational stability of the equipment.
