Description

Technical Field

[0001] This utility model relates to the field of cold storage defrosting technology, and in particular to a defrosting device. Background Technology

[0002] Cold storage, also known as refrigerated warehouse, is a type of warehouse that uses cooling facilities to create suitable humidity and low temperature conditions. It is specifically used for processing and storing agricultural and livestock products, allowing these products to escape the effects of climate, thereby extending their storage and preservation time, and ultimately regulating market supply. Cold storage is widely used in many fields.

[0003] Cold storage facilities typically develop frost on their surfaces during long-term use. Therefore, to ensure the efficiency of cold storage operations, regular defrosting is necessary. The most challenging part of defrosting is cleaning the frost on the roof. Conventional methods often involve manual labor using a long pole with a shovel at the end to scrape away the frost. This method is not only labor-intensive and time-consuming, but the scraped-off frost can also fall onto workers' heads and bodies, causing discomfort. Furthermore, the fallen frost on the ground increases subsequent cleanup work, making the overall cleaning process inconvenient. Utility Model Content

[0030] Reference Figure 1-4 This utility model provides an embodiment of a defrosting device, including a base 1. Four casters 2 are provided at the bottom of the base 1, located on both sides of the bottom of the base 1 near the ends. Each caster 2 has a wheel brake for positioning when not in use. A fixed frame 3 is fixedly connected to the top of the base 1. A lifting frame 5 is provided on one side of the fixed frame 3, and a lifting mechanism is provided between the fixed frame 3 and the lifting frame 5. Two sets of fixed frames 3, lifting frames 5, and lifting mechanisms are provided, located on both sides of the top of the base 1. A defrosting mechanism is provided on the lifting frame 5, and a receiving frame 15 is fixedly connected to the lifting frame 5. (See attached diagram.) Figure 1 As shown, the receiving rack 15 is located directly below the defrosting mechanism. Its function is to receive the frost that falls after defrosting the top of the cold storage. The top of the receiving rack 15 is open and the bottom is through-hole, which allows the falling frost to be concentrated in the middle and discharged from the bottom. One end of the bottom plate 16 is rotatably connected to one side of the bottom of the receiving rack 15 by a rotating part 17. The rotating part 17 can be a hinge, which is a conventional existing technology product and will not be described in detail. The bottom plate 16 can cover the bottom of the receiving rack 15, so that the falling frost can be collected in a concentrated manner during defrosting. After opening the bottom plate 16, the frost in the receiving rack 15 can be cleaned out.

[0031] The lifting mechanism includes a groove 6 on a fixed frame 3, a threaded rod 7 rotatably connected within the groove 6, and a lifting block 8 threadedly fitted onto the threaded rod 7. The threaded rod 7 is positioned at its contact point with the inner wall of the groove 6 via a bearing. The lifting block 8 and the groove 6 are nested and slidingly fitted. The threaded rod 7 can be a self-locking thread, which provides a self-locking effect after lifting adjustment, preventing it from rotating independently and causing the lifting mechanism to slip. The lifting block 8 is fixedly connected to the lifting frame 5. The fixed frame 3 has a placement slot 9, within which a motor 10 is fixedly installed. A mounting plate is welded to the motor 10. The mounting plate is fixed to the inner wall of the placement slot 9 by bolts. This is a conventional motor installation method and will not be described in detail. The output end of the motor 10 is fixedly connected to the threaded rod 7. The motor 10 can be a stepper motor. Stepper motors have a good self-locking effect. This combination with the threaded rod 7 can stably position the lifting frame 5 after lifting and adjusting, and it is not easy to slip, thus ensuring the stability of the structural positioning. When running, start the motor 10. The motor 10 drives the threaded rod 7 to rotate. The threaded rod 7 drives the lifting block 8 to rise and fall. This will drive the defrosting mechanism to rise and fit against the top of the cold storage, which will facilitate subsequent defrosting work.

[0032] The defrosting mechanism includes a rotating roller 11 rotatably connected to the lifting frame 5. The central axis of the rotating roller 11 is positioned and installed at the connection point with the lifting frame 5 via a bearing. A scraper 12 is fixedly connected to the outer surface of the rotating roller 11, as shown in the attached figure. Figure 1 As shown, multiple scrapers 12 are evenly distributed on the outer surface of the rotating roller 11. The function of the scrapers 12 is to scrape off the frost on the top of the cold storage when the rotating roller 11 rotates, thereby achieving convenient and stable defrosting of the top of the cold storage. The lifting frame 5 is provided with a second placement slot 13, and a second motor 14 is fixedly installed in the second placement slot 13. A mounting plate is welded to the second motor 14, and the mounting plate is fixed in the second placement slot 13 by bolts. This is a conventional motor fixing installation method, which will not be described in detail. The output end of the second motor 14 is fixedly connected to the central axis of the rotating roller 11. When running, the second motor 14 drives the rotating roller 11 to rotate, and the rotating roller 11 drives the scrapers 12 to revolve. When the scrapers 12 rotate to the top position, they can contact the frost on the top of the cold storage and scrape it off, thereby achieving convenient defrosting of the top of the cold storage.

[0033] A reinforcing rib 4 is fixedly connected between the top of the base 1 and the outer surface of the fixing frame 3. The setting of the reinforcing rib 4 can enhance the positioning stability of the fixing frame 3 structure.

[0034] One end of the bottom plate 16 is fixedly connected to a fixed shaft 18, and a fastening pin 19 is nested and rotatably connected to the fixed shaft 18. A retaining ring 20 is fixedly connected to one side of the outer surface of the receiving frame 15 near the bottom. The fastening pin 19 and the retaining ring 20 are fastened together, and there are two sets of fastening pins 19 and retaining rings 20. During operation, the fastening pin 19 is rotated to insert into the retaining ring 20, which fixes the bottom plate 16. Similarly, the fastening pin 19 is opened, which allows the bottom plate 16 to be rotated open, making it easy to clean the frost inside the receiving frame 15.

[0035] The top of the base 1 is equipped with a fixed box 21, and the fixed box 21 contains a controller 22 and a battery 23. The motor 10, motor 24, controller 22, and battery 23 are all electrically connected through connecting wires, which can realize the stable operation of the entire structure. The controller 22 can be in the form of a switch control button, which is a conventional technical product and will not be described in detail.

[0036] Working principle: When using the defrosting device, the lifting mechanism drives the lifting frame 5 to rise, and the lifting frame 5 drives the scraper 12 on the rotating roller 11 to rise and fit against the top of the cold storage. The second motor 14 is started, and the second motor 14 drives the rotating roller 11 to rotate. The rotating roller 11 drives the scraper 12 to revolve, and the scraper 12 can scrape down the frost on the top of the cold storage to complete the defrosting work. The scraped frost automatically falls into the receiving rack 15. After the defrosting work is completed, the fastening pin 19 is rotated to open the bottom plate 16, so that the frost in the receiving rack 15 can be cleaned out, and the cleaning work is completed.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
