Description

Technical Field

[0001] The utility model relates to the technical field of defrosting mechanisms, in particular to a defrosting mechanism for low-temperature storage. Background Art

[0002] With the rapid development of the cold chain logistics industry, low-temperature storage facilities play a crucial role in the storage of sensitive items such as food and medicine. However, in the long-term low-temperature environment, frost often forms inside the storage due to the condensation of water vapor in the air on the low-temperature surface. Therefore, the frost needs to be cleaned regularly.

[0003] Currently, when cleaning the frost, as in the patent with the authorized announcement number CN207894104U in the prior art, this utility model discloses a defrosting device for a small cold storage, including a defrosting box, a jet plate, and a water spray gun. The jet plate and the water spray gun are both arranged on the top of the defrosting box. The bottom of the jet plate is provided with a telescopic pipe and a fixed pipe, and the fixed pipe is nested in the telescopic pipe and embedded in the defrosting box. The bottom of the water spray gun is provided with a connecting pipe, and the connecting pipe is embedded in the water spray gun. The bottom end of the connecting pipe is provided with a fixed end head, and the connecting pipe is movably connected to the defrosting box through the fixed end head.

[0004] However, it is found in the use of this device that it is not convenient to collect the cleaned frost, and it is easy to cause water accumulation on the ground inside the storage after defrosting, increasing the complexity of cleaning the water later and reducing the convenience of use. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a defrosting mechanism for low-temperature storage that avoids water accumulation on the storage floor caused by defrosting and improves the convenience of defrosting treatment at different positions in the storage.

[0006] A defrosting mechanism for low-temperature storage of the present utility model includes a cover body and a rod brush. The rod brush is rotatably installed on the inner side wall of the cover body. It also includes a support device, a driving device, a collection device, a first motor, a first connecting arm, and a second connecting arm. The first motor is installed on the outer side wall of the cover body, and the output end of the first motor is connected to the rod brush. The bottom end of the first connecting arm is connected to the outer side wall of the cover body, and the top end of the first connecting arm is rotatably connected to the front end of the second connecting arm. The rear end of the second connecting arm is installed on the support device, and the support device is used to drive the second connecting arm to move and adjust. A driving device is arranged on the outer side wall of the second connecting arm, and the driving device is used to drive the first connecting arm to rotate and swing. The cover body is communicated with the collection device, and the collection device is used to collect the ice and frost. By driving the second connecting arm to move downward through the support device, the second connecting arm drives the rod brush to move downward to contact the storage ground. Then, the first motor drives the rod brush to rotate, so that the rod brush clears the ice and frost on the storage ground. At the same time, the collection device sucks air into the cover body, so that the ice and frost enter the collection device for storage, avoiding the situation of water accumulation on the storage ground caused by defrosting. When defrosting the storage wall and ceiling is required, the driving device drives the first connecting arm to swing and rotate to a horizontal angle and a vertical angle, so that the cover body moves to the side or the top, improving the convenience of the mechanism for defrosting different positions in the storage.

[0007] Preferably, the collection device includes a box body, a grille, a valve, a fan, and a hose. The grille is installed on the inner side wall of the box body.

The input end of the fan is communicated with the inside of the box body, and a filter screen is arranged on the input end of the fan. The input end of the hose is communicated with the inside of the cover body, and the output end of the hose is communicated with the box body. By sucking air into the box body through the fan, the box body sucks air into the cover body through the hose, so that the cover body collects the ice and frost cleared by the rod brush. The collected ice and frost are transported to the inside of the box body through the hose, so that the ice and frost are stored at the top end of the grille. The water after the ice and frost melt falls to the bottom of the box body, and the water is discharged by opening the valve, thereby improving the convenience of ice and frost collection and centralized treatment.

[0008] Preferably, the driving device includes a chassis, a worm, a worm gear, and a second motor. The chassis is installed on the outer side wall of the second connecting arm.

The worm is meshed with the worm gear. The second motor is installed on the outer side wall of the chassis, and the output end of the second motor is connected to the worm. By driving the worm to rotate through the second motor, the worm drives the first connecting arm to rotate through the meshing with the worm gear, so that the first connecting arm drives the cover body to move to different positions, improving the convenience of the mechanism for defrosting different positions in the storage.

[0009] Preferably, the support device includes a power device, an electric rotating table and a guide member. The electric rotating table is installed at the top end of the box body. The bottom end of the guide member is connected to the rotating end of the electric rotating table. The end of the second connecting arm is slidably installed on the guide member up and down through the power device. The power device drives the second connecting arm to slide up and down, so that the second connecting arm drives the cover body to move up and down for adjustment. The electric rotating table drives the guide member to rotate, so that the guide member drives the cover body to move to different positions, improving the flexibility of the movement and use of the cover body.

[0010] Preferably, the power device includes a lead screw and a third motor. The lead screw is rotatably installed on the inner side wall of the guide member. The third motor is installed at the top end of the guide member. The output end of the third motor is connected to the lead screw. The second connecting arm is fitted and screwed on the outer side wall of the lead screw. The third motor drives the lead screw to rotate, so that the lead screw drives the second connecting arm to move up and down, improving the convenience of the movement and adjustment of the cover body.

[0011] Preferably, it further includes a vehicle body, and the vehicle body is installed at the bottom end of the box body. The vehicle body drives the box body to move, improving the convenience of the overall movement and walking of the mechanism.

[0012] Preferably, it further includes a delivery pipe. The top end of the delivery pipe is communicated with the output end of the blower, and the bottom end of the delivery pipe is communicated with the inside of the box body. By providing the delivery pipe, it is convenient to discharge the water in the blower into the box body, reducing the accumulation of water in the blower.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The support device drives the second connecting arm to move downward, so that the second connecting arm drives the rod brush to move downward to contact the storage floor. Then, the first motor drives the rod brush to rotate, so that the rod brush clears the frost on the storage floor. At the same time, the collection device sucks air inside the cover body, so that the frost enters the collection device for storage, avoiding the situation of water accumulation on the storage floor caused by defrosting. When defrosting the storage wall and ceiling is required, the driving device drives the first connecting arm to swing and rotate to a horizontal angle and a vertical angle, so that the cover body moves to the side or the top, improving the convenience of the mechanism for defrosting different positions in the storage.
