DETAILED DESCRIPTION

[0031] See also Figures 1 to 4: The utility model provides a continuous heat preservation three-dimensional cold storage, including a cold storage body 1, a concave scraper 2, a cleaning mechanism and a driving device. The cold storage body 1 is arranged in a square shape; the concave scraper 2 is movably arranged in the cold storage body 1 along the length direction, and the outer side walls of the concave scraper 2 are respectively abutted against the inner side walls and the inner top wall of the cold storage body 1; the cleaning mechanism includes two mounting covers 8, two rectangular groove shells 9, two rotating shafts 10, two circular gears 11, two racks 12 and a cleaning roller 13; the two mounting covers 8 are respectively fixed on the lower sides of the two vertical ends of the concave scraper 2, and the two rectangular groove shells 9 are fixed on the inner bottom surface of the cold storage body 1 at intervals along the width direction, and the lower end of the mounting cover 8 and the inner side wall of the rectangular groove shell 9 are respectively fixed on the inner bottom surface of the cold storage body 1 at intervals along the width direction. The upper ends are both opened; the two rotating shafts 10 are respectively inserted and rotatably arranged on the side wall opposite to the mounting cover 8, the two circular gears 11 are correspondingly installed in the two mounting covers 8 and fixedly connected to the rotating shaft 10, the two racks 12 are respectively fixed on the inner bottom surfaces of the two rectangular groove shells 9, the racks 12 are meshed with the circular gears 11, the cleaning roller 13 is fixed between the two rotating shafts 10, and the side wall of the cleaning roller 13 is in contact with the inner bottom surface of the cold storage body 1; and the driving device is used to drive the concave scraper 2 to move along the length direction.

[0032] By bringing the concave scraper 2 into contact with the inner side wall and the inner top wall of the cold storage body 1, when the inside of the cold storage body 1 needs to be cleaned, the concave scraper 2 is driven to move by the driving device, so that impurities such as water drops adhering to the inner wall of the cold storage body 1 can be scraped off, which makes cleaning convenient, saves manpower and has high cleaning efficiency; at the same time, the movement of the concave scraper 2 will drive the installation cover 8 to move, thereby driving the circular gear 11 in the installation cover 8 to translate synchronously. Since the two circular gears 11 are respectively engaged with the two racks 12, at this time, the two circular gears 11 rotate, thereby driving the two rotating shafts 10 to rotate, thereby realizing the automatic displacement and rotation of the cleaning roller 13, and the inner bottom surface of the cold storage body 1 can be cleaned. There is a lot of garbage on the inner bottom surface of the cold storage body 1 and it is difficult to clean. The rotating cleaning roller 13 is used to make the cleaning effect better.

[0033] Among them, the continuous heat preservation three-dimensional cold storage is a common existing technology, and the structure of the cold storage body 1 is not introduced in detail here.

[0034] In this embodiment, the driving device includes two L-shaped frames 3, a screw rod 5, a driving motor 4, a threaded block 6 and a movable plate 7. The two L-shaped frames 3 are fixed on the inner top wall of the cold storage body 1 at intervals along the length direction; the two ends of the screw rod 5 are rotatably connected to the L-shaped frames 3; the output shaft of the driving motor 4 is fixedly connected to one end of the screw rod 5; the threaded block 6 is threadedly connected to the screw rod 5; the movable plate 7 is fixed on both sides of the threaded block 6, and the end of the movable plate 7 away from the threaded block 6 is fixedly connected to the inner side wall of the concave scraper 2.

[0035] By starting the driving motor 4, the screw rod 5 is driven to rotate. Since the screw rod 5 is threadedly connected to the threaded block 6, the threaded block 6 moves along the length direction, driving the concave scraper 2 to translate, so that impurities such as water drops adhering to the top wall and the inner side wall of the cold storage body 1 can be scraped off, which is convenient for cleaning, saves manpower and has high cleaning efficiency. At the same time, the concave scraper 2 will drive the cleaning mechanism to move, and then clean the inner bottom surface of the cold storage body 1.

[0036] In another embodiment, the driving device includes a second motor, and the output shaft of the second motor passes through any one of the mounting covers 8 and is coaxially fixedly connected to the corresponding circular gear 11 .

[0037] The circular gear 11 is directly driven to rotate by the second motor, thereby driving the cleaning roller 13 to rotate, and displaced in the length direction under the meshing action of the circular gear 11 and the rack 12, so that the mounting cover 8 is displaced accordingly, and then continues to drive the concave scraper 2 to move in the length direction, thereby cleaning the inner side wall, inner top wall and inner bottom surface of the cold storage body 1.

[0038] During use, the two embodiments can be combined to form a new embodiment according to actual needs, so that the drive motor 4 is set to drive the screw 5 to rotate and the second motor is set to drive the circular gear 11 to rotate, so that the drive motor 4 and the second motor are started at the same time by setting parameter control, thereby ensuring that the concave scraper 2 and the cleaning roller 13 move at the same time.

[0039] Furthermore, the rear sides of the two mounting covers 8 are fixedly connected with mounting frames 14 , and a baffle 15 is fixedly connected between the two mounting frames 14 . The baffle 15 is arranged to cover the outer side of the cleaning roller 13 .

[0040] By providing the baffle 15, it is possible to prevent the cleaned garbage from splashing when the cleaning roller 13 rotates to clean the garbage.

[0041] Furthermore, a scraping layer is fixed to the outer wall of the concave scraper 2, and the scraping layer is made of rubber. The scraping layer made of rubber has good friction with the inner wall surface of the cold storage body 1. On the one hand, compared with metal, the material can better protect the inner wall surface of the cold storage body 1 and keep it smooth; on the other hand, it can clean the water droplets and other garbage on the inner wall surface of the cold storage body 1 more cleanly.

[0042] Furthermore, the threaded block 6 and the movable plate 7, as well as the movable plate 7 and the concave scraper 2, are fixedly connected by welding, and the connection is firm.

[0043] Furthermore, a through hole is formed on the side wall of the mounting cover 8 , and the through hole is rotatably connected to the rotating shaft 10 via a bearing member, so as to facilitate the rotation of the rotating shaft 10 .

[0044] Specifically, a control switch 16 is fixedly connected to the inner wall of the cold storage body 1, and one end of the control switch 16 is electrically connected to the driving device, which is easy to operate and has an external power supply. The circuit involved is a prior art and can be fully implemented by those skilled in the art without further elaboration.

[0045] Furthermore, two positioning slide bars 17 are fixedly connected between the inner walls on both sides of the cold storage body 1. The two positioning slide bars 17 are respectively arranged to penetrate the two movable plates 7, so that the displacement of the two movable plates 7 is more stable.

[0046] Specifically, the L-shaped frame 3 is rotatably connected to one end of the screw rod 5 via a bearing seat, and can support and stabilize the rotation of the screw rod 5 .

[0047] Specifically, the lower end side wall of the mounting cover 8 is frictionally connected with the upper end side wall of the rectangular tank shell 9, so that the displacement of the mounting cover 8 is more stable.

[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
