Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cold storage and cold storage water diversion equipment, specifically a structure for diverting and collecting condensate from the top of a cold storage. Background Technology
[0002] Cold storage facilities are mainly used for the low-temperature storage and preservation of food, pharmaceuticals, chemical raw materials, and other items. They maintain a constant low-temperature environment (typically -18°C to 10°C) inside the storage facility through a refrigeration system to slow down the spoilage of goods. Currently, condensate drainage in cold storage facilities mostly relies on inclined metal plates installed on the roof. Gravity causes the condensate to flow along the plate surface to the edges, and then through drainage channels fixed to the walls into drain pipes for discharge.
[0003] However, to ensure usable space in cold storage, the metal plate surface is typically tilted at a small angle, resulting in slow condensate flow and easy water accumulation on the plate surface. At the same time, the circulating cold air inside the cold storage can easily blow away condensate that has not been discharged in time, causing it to deviate from the preset flow path and drip directly onto the surface of the goods inside the storage. This not only affects the quality of goods storage but also increases the energy consumption of the refrigeration system due to water droplet evaporation. Furthermore, the scattered condensate can easily cause safety hazards such as pipe freezing and slippery ground in low-temperature environments. Therefore, it is necessary to redesign a condensate drainage and collection structure on the top of the cold storage to address the above problems. Utility Model Content

[0008] Preferably, the pressurized water discharge assembly includes a water outlet, which is located on the bottom surface of the movable seat. A fixing plate is fixedly installed on the bottom surface of the movable seat, and multiple spring telescopic rods are installed on the outer side of the fixing plate.

[0009] Preferably, the movable base has water inlets on both outer sides, and each water inlet corresponds to a water guide plate. Multiple heating wires are installed on the inner walls of both sides of the movable base.
[0010] Preferably, the moving mechanism includes a limiting rod, which is installed between the inner walls of both sides of the cold storage body. The inner walls of both sides of the cold storage body are rotatably connected to a threaded rod, and both the limiting rod and the threaded rod are located above the inclined plate. A threaded sleeve is threadedly connected to the outer side of the threaded rod, and the threaded sleeve is slidably connected to the limiting rod. The bottom end of the threaded sleeve is fixedly connected to the moving seat. A drive motor is fixedly installed on the side wall of the cold storage body, and the output shaft of the drive motor is coaxially connected to the threaded rod.

[0013] Compared with the prior art, this utility model provides a condensate drainage and collection structure for the top of a cold storage facility, which has the following beneficial effects:
[0014] 1. This utility model achieves efficient directional collection and rapid discharge of condensate through devices such as inclined plates, movable seats, water guide plates, flow channels, pressurized water discharge components, baffles, and collection seats. The inner arc design on both sides of the flow channel, combined with the tilt angle of the inclined plates, uses the surface tension of water to constrain the flow path of condensate and reduce cold air interference. The movable seat drives the water collection rod to slide in the flow channel, actively collecting and dispersing condensate. Together with the water guide plate, it forms a semi-enclosed collection space, isolating the direct impact of cold air. The pressurized water discharge component works with the baffle to automatically open the drainage when the movable seat reaches the collection seat. Compared with the traditional natural flow mode, it significantly improves the speed of condensate collection and discharge and avoids water accumulation.
[0015] 2. This utility model achieves stable storage, automatic flow control, and anti-icing functions for condensate through devices such as a water storage component, spring telescopic rod, sealing plate, and heating wire. The pressure-controlled drainage structure composed of the spring telescopic rod and sealing plate can precisely control the drainage timing and avoid leakage during non-collection stages. The heating wire adopts a low-temperature heating mode to prevent condensate in the moving base from freezing and clogging. The water storage component stores condensate after purification through a filter, and the drain pipe controlled by a solenoid valve facilitates secondary use and allows for on-demand discharge, ensuring continuous and stable operation of the system in low-temperature environments.

[0024] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.
[0025] This utility model provides a technical solution for a condensate drainage and collection structure at the top of a cold storage facility:
[0026] Please see Figures 1-7 A condensate drainage and collection structure for the top of a cold storage unit includes a cold storage body 1. Inclined plates 5 are installed at an angle between the two side walls of the cold storage body 1. Multiple guide grooves 11 are linearly and equidistantly opened on the bottom surface of the inclined plates 5. A movable seat 6 is slidably connected to the bottom surface of the inclined plates 5. A moving mechanism is installed on the inner top of the cold storage body 1, and the moving mechanism drives the movable seat 6 to slide. Multiple water collecting rods 12 are installed on the top surface of the movable seat 6, and each water collecting rod 12 is slidably connected in the corresponding guide groove 11. Two water guiding plates 13 are installed at an angle on both outer sides of the movable seat 6. A pressurized water discharge component is installed on the bottom surface of the movable seat 6. A collection seat 23 is fixedly installed on the side wall of the cold storage body 1. A baffle 22 is fixedly installed on the top surface of the collection seat 23. A water storage component is installed on the outer side of the cold storage body 1, and the water storage component is connected to the collection seat 23.
[0027] It should be noted that each guide channel 11 has an inward arc shape on both sides. Through the surface tension of the water itself, the possibility of condensate dripping off on its own can be reduced. Furthermore, through the inclined plate 5, the condensate can slide down into the collection seat 23 under its own gravity.
[0028] Furthermore, by sliding the water collecting rod 12 within the guide channel 11, condensate can be gradually accumulated and dripped onto the guide plate 13. As the guide plate 13 tilts, it automatically slides into the movable seat 6, completing the initial collection of condensate.
[0029] Furthermore, the pressurized water discharge assembly includes an outlet 18, which is located on the bottom surface of the movable seat 6. A fixed plate 15 is fixedly installed on the bottom surface of the movable seat 6. Multiple spring telescopic rods 16 are installed on the outer side of the fixed plate 15. A sealing plate 17 is slidably connected to the bottom surface of the movable seat 6. The sealing plate 17 is used to block the outlet 18. The telescopic end of each spring telescopic rod 16 is fixedly connected to the outer side of the sealing plate 17. The position of the sealing plate 17 corresponds to the baffle 22. The baffle 22 squeezes the sealing plate 17 and compresses the multiple spring telescopic rods 16, thereby opening the outlet 18 and realizing automatic drainage into the collection seat 23.
[0030] Furthermore, water inlets 19 are provided on both outer sides of the movable seat 6, and each water inlet 19 corresponds to a water guide plate 13. Multiple heating wires 14 are installed on both inner walls of the movable seat 6. It should be noted that the heating wires 14 adopt a low-temperature heating mode, and their heat only prevents the water in the movable seat 6 from freezing, and will not have a significant impact on the temperature of the cold storage body 1 itself.
[0031] Furthermore, the moving mechanism includes a limiting rod 7, which is installed between the inner walls of both sides of the cold storage body 1. The inner walls of both sides of the cold storage body 1 are rotatably connected to a threaded rod 8. The limiting rod 7 and the threaded rod 8 are both located above the inclined plate 5. The outer side of the threaded rod 8 is threadedly connected to a threaded sleeve 9, which is slidably connected to the limiting rod 7. The bottom end of the threaded sleeve 9 is fixedly connected to the moving seat 6. A drive motor 10 is fixedly installed on the side wall of the cold storage body 1, and the output shaft of the drive motor 10 is coaxially connected to the threaded rod 8.
[0032] The bottom surface of the threaded sleeve 9 is fixedly connected to the movable seat 6 through two connecting plates, and the inclined plate 5 is provided with a through groove for the movement of the connecting plate.
[0033] Furthermore, the water storage component includes a water storage tank 4, which is fixedly installed on the outside of the cold storage body 1. A drain pipe 20 is fixedly connected to the outside of the water storage tank 4, and a solenoid valve 21 is installed on the outside of the drain pipe 20. A filter 3 is fixedly connected to the top surface of the water storage tank 4, and a guide pipe 2 is connected to the top of the filter 3. The guide pipe 2 is connected to the collection seat 23. After the water is purified by the filter 3, it enters the water storage tank 4 for subsequent recycling.
[0034] Furthermore, each water collecting rod 12 has an inverted trapezoidal cross-section, and a trapezoidal groove 24 is provided in the collecting seat 23, and the guide pipe 2 is connected to the trapezoidal groove 24.
[0035] In practical use, the working principle of this utility model is as follows:
[0036] First, when the cold storage body 1 is running, water vapor condenses into condensate on the surface of the inclined plate 5. Because the two sides of the guide channel 11 are inwardly curved, the surface tension of the water reduces the self-dripping. The condensate flows along the guide channel 11 on the inclined plate 5.
[0037] When the drive motor 10 starts, it drives the threaded rod 8 to rotate. The threaded sleeve 9 moves along the limit rod 7 and drives the movable seat 6 to slide below the inclined plate 5 through the connecting plate. The connecting plate moves in the through groove. During the movement, the water collecting rod 12 slides in the guide groove 11 to accumulate condensate, which drips onto the guide plate 13 and enters the movable seat 6 through the inlet 19 along the guide plate 13.
[0038] When the moving seat 6 is above the collecting seat 23, the baffle 22 squeezes the sealing plate 17 to open the outlet 18, and the condensate flows into the collecting seat 23. After passing through the trapezoidal groove 24 and the guide pipe 2 to the filter 3, it enters the water storage tank 4. When it needs to be discharged, the solenoid valve 21 is opened and the water is discharged through the drain pipe 20. The heating wire 14 heats the water at a low temperature to prevent the water in the moving seat 6 from freezing, thus ensuring the stable operation of the device.
[0039] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
