Description

Technical Field

[0001] This utility model relates to the field of overflow drainage technology, specifically to an overflow drainage structure for a refrigeration system. Background Technology

[0002] Overflow drainage is a process that uses the liquid's own weight or external pressure difference to automatically discharge excess liquid from a container or system that exceeds a set liquid level through a pre-set overflow channel (such as an overflow pipe or weir). Its core principle is that when the liquid level rises to the overflow port height, the liquid naturally overflows due to gravity, thereby maintaining a stable liquid level and preventing overfilling.

[0003] In existing technologies, many traditional overflow drainage structures use permanent connections such as welding and bonding to fix components together to ensure sealing. For example, the drain pipe is often welded to the sump and drain pump. If a component fails and needs replacement, it is difficult to disassemble it individually; often, the entire drainage structure needs to be disassembled, which is not only complex but also prone to damaging other intact components, increasing maintenance costs and time. Therefore, we propose an overflow drainage structure for refrigeration systems. Utility Model Content

[0004] The purpose of this invention is to provide a refrigeration system overflow drainage structure to address the problem described in the background section where many traditional overflow drainage structures rely on permanent connections such as welding and bonding to fix components together in order to ensure sealing. For example, the drain pipe is often welded to components like the sump and drain pump. If a component malfunctions and needs replacement, it is difficult to disassemble it individually; often, the entire drainage structure needs to be disassembled, which is not only complex but also prone to damaging other intact components, increasing maintenance costs and time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigeration system overflow drainage structure, comprising: a refrigeration component, one end of which is fixedly connected to an overflow drainage port, a sealing gasket installed on the outer wall of the overflow drainage port, a connecting pipe installed on one end of the overflow drainage port, a valve fixedly connected to the outer surface of the overflow drainage port, a fixing frame fixedly connected to one end of the connecting pipe, and a quick-release mechanism provided at one end of the fixing frame.

[0006] Preferably, a first mounting ring is installed at the top of the overflow drain and the outer wall of the connecting pipe, and a second mounting ring is installed at the bottom of the overflow drain and the outer wall of the connecting pipe. A threaded rod is connected through the outer surfaces of the first mounting ring and the second mounting ring, and a nut is threaded onto the outer wall of the threaded rod.

[0007] Preferably, the quick-release mechanism includes a fixed frame fixedly connected to one end of the connecting tube, the inner wall of the fixed frame having a groove, and a first spring installed on the inner wall of the groove.

[0008] Preferably, a first pressure plate is fixedly connected to the top of the first spring, a square groove is provided on the outer wall of the fixed frame, and a pressing rod is fixedly connected to the top of the first pressure plate.

[0009] Preferably, a connecting plate is fixedly connected to one side of the first pressure plate, a second pressure plate is fixedly connected to one side of the connecting plate, and a second spring is fixedly connected to the top of the second pressure plate.

[0010] Preferably, a locking block is fixedly connected to the bottom of the second pressure plate, an installation plate is placed inside the fixing frame, locking plates are fixedly connected to both sides of the installation plate, a through hole is opened on the upper surface of the locking plate, and a drain pipe is fixedly connected to one end of the installation plate.

[0011] This utility model has at least the following beneficial effects:

[0012] (1) The quick-release mechanism allows maintenance personnel to quickly separate the components of the drain pipe without the need for complex tools, simply through simple operation. Compared to using permanent connection methods such as welding or bonding to fix the components together, this mechanism can significantly shorten the disassembly time, significantly reduce equipment downtime, and improve production efficiency, making it particularly suitable for industrial refrigeration scenarios with high requirements for timely maintenance. The quick-release drain pipe facilitates comprehensive internal cleaning, and regular pipe disassembly can promptly remove accumulated dirt and impurities, effectively preventing pipe blockage problems. When a drainage failure occurs in the system, the internal condition can be visually inspected after quick pipe disassembly, quickly locating blockage points, damage points, and other fault locations, greatly improving the efficiency of fault diagnosis.

[0013] (2) Through the cooperation between the first mounting ring, the second mounting ring, the threaded rod and the nut, the connecting pipe is pressed tightly onto the sealing surface of the overflow drain by uniform tightening. The applied pressure can fully deform the sealing ring between the connecting pipe and the drain, fill the tiny gaps and form a reliable sealing structure. This operation method greatly shortens the maintenance and repair time of the drain structure. When it is necessary to clean the pipe or replace the parts, the downtime of the equipment can be significantly reduced. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a refrigeration system overflow drainage structure, including: a refrigeration component 1, an overflow drainage port 2 fixedly connected to one end of the refrigeration component 1, a sealing gasket 21 installed on the outer wall of the overflow drainage port 2, a connecting pipe 22 installed at one end of the overflow drainage port 2, a valve 3 fixedly connected to the outer surface of the overflow drainage port 2, a fixing frame 5 fixedly connected to one end of the connecting pipe 22, and a quick-release mechanism 502 provided at one end of the fixing frame 5.

[0021] A first mounting ring 4 is installed at the top of the overflow drain port 2 and the outer wall of the connecting pipe 22, and a second mounting ring 41 is installed at the bottom of the overflow drain port 2 and the outer wall of the connecting pipe 22. A threaded rod 42 is connected through the outer surfaces of the first mounting ring 4 and the second mounting ring 41, and a nut 43 is threadedly connected to the outer wall of the threaded rod 42.

[0022] During installation, the operator aligns the connecting pipe 22 with the overflow drain port 2, then installs the sealing gasket 21 onto the overflow drain port 2. Next, the first mounting ring 4 and the second mounting ring 41 are fitted onto the overflow drain port 2 and the connecting pipe 22. Then, the threaded rod 42 is inserted into the first mounting ring 4 and the second mounting ring 41, and the nut 43 is installed onto the threaded rod 42 and tightened, thus fixing and sealing the overflow drain port 2 and the connecting pipe 22. Through the cooperation between the first mounting ring 4, the second mounting ring 41, the threaded rod 42, and the nut 43, the connecting pipe 22 is tightly pressed against the sealing surface of the overflow drain port 2 by uniform tightening. The applied pressure allows the sealing gasket 21 between the connecting pipe 22 and the drain port to fully deform, filling the tiny gaps and forming a reliable sealing structure. This operation method significantly shortens the maintenance and repair time of the drain structure, and can significantly reduce equipment downtime when cleaning the pipes or replacing parts is required.

[0023] The quick-release mechanism 502 includes a fixed frame 5 fixedly connected to one end of the connecting tube 22. The inner wall of the fixed frame 5 has a groove 51. A first spring 52 is installed on the inner wall of the groove 51. A first pressure plate 53 is fixedly connected to the top of the first spring 52. The outer wall of the fixed frame 5 has a square groove 54. A pressing rod 55 is fixedly connected to the top of the first pressure plate 53. A connecting plate 56 is fixedly connected to one side of the first pressure plate 53. A second pressure plate 57 is fixedly connected to one side of the connecting plate 56. A second spring 58 is fixedly connected to the top of the second pressure plate 57. A locking block 59 is fixedly connected to the bottom of the second pressure plate 57. An installation plate 6 is placed inside the fixed frame 5. Locking plates 61 are fixedly connected to both sides of the installation plate 6. A through hole 501 is opened on the upper surface of the locking plate 61. A drain tube 7 is fixedly connected to one end of the installation plate 6.

[0024] At the same time, the operator presses down on the pressing rod 55, causing the first spring 52 to contract downwards. As the first spring 52 contracts, it drives the second spring 58 to contract upwards, causing the locking block 59 to lift up. This allows the locking plate 61 to be pulled out from the through hole 501 inside the locking block 59 and then slide out along the groove 51, thereby allowing the drain pipe 7 on the mounting plate 6 to be removed. During installation, the mounting plate 6 is aligned with the fixing frame 5 and installed. The locking plate 61 enters directly below the locking block 59 along the groove 51. At this time, the pressing rod 55 is pressed down, and the locking plate 61 is aligned with the through hole 501 on the locking block 59. The through hole 501 acts as a limit. Installing the locking block 59 into the through hole 501 makes the drain pipe 7 more secure after installation. Then, the pressing rod 55 is released, and the first spring 52 and the second spring 58 return to their original positions, allowing the drain pipe 7 to be installed onto the fixing frame 5. The liquid generated by the operation of the refrigeration component 1 flows to the surface of the base plate. When it is necessary to drain the liquid, the valve 3 on the overflow drain port 2 is opened, and the liquid flows out through the drain pipe 7.

[0025] The quick-release mechanism 502 allows maintenance personnel to quickly separate the seven components of the drain pipe without the need for complex tools, using only simple operations. Compared to permanent connections such as welding or bonding, this mechanism significantly reduces disassembly time, minimizes equipment downtime, and improves production efficiency, making it particularly suitable for industrial refrigeration scenarios with high requirements for timely maintenance. The seven quickly detachable drain pipes facilitate thorough internal cleaning. Regular disassembly of the pipes removes accumulated dirt and impurities, effectively preventing pipe blockages. When a drainage failure occurs, quick pipe disassembly allows for direct inspection of the internal condition, quickly locating blockages, damage points, and other fault locations, greatly improving troubleshooting efficiency.
