Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration and fresh-keeping of fruits and vegetables, in particular to a grape storage rack for refrigeration. Background Art

[0002] Grapes, a nutritious fruit, are rich in sugar and water. However, during long-term storage, these components can easily become a breeding ground for microorganisms, leading to rot and resulting in economic losses. To ensure that grapes can deliver higher economic returns, refrigerated storage is commonly used to extend their freshness and shelf life while preserving their optimal taste and nutritional value. During refrigerated storage, in addition to the storage environment, ensuring the quality of the stored fruit is also crucial. Currently, maintaining the quality of stored fruit mainly relies on pre-warehousing sorting and culling. After storage, the fruit is typically stored in sealed boxes or dedicated turnover baskets. Due to the irregular shape of grapes, their placement is more complex than that of other fruits and vegetables. Using sealed boxes and turnover baskets for long-term storage hinders the dissipation of heat generated by the grapes' respiration, easily leading to localized overheating and accelerated fruit spoilage. If not detected in time, once the spoilage spreads, it can cause significant economic losses. Therefore, it is necessary to develop a refrigerated grape storage device that can detect and effectively avoid local overheating and can dissipate heat to stored fruits in time. Utility Model Content

[0003] In response to the above technical problems, the utility model provides a grape refrigeration storage rack that can detect whether local heat release occurs during the storage process of the fruit and make timely adjustments to solve the problem of local overheating during the storage process of grapes affecting the quality of the fruit.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a refrigerated grape storage rack, comprising a base and a support plate, the base being fixedly connected to the support plate, the support plate being rotatably connected to a plurality of rotating shafts and the rotating shafts vertically passing through the support plate, the base being fixedly connected to a motor, the motor being transmission-connected to the rotating shafts, automatic telescopic rods being fixedly connected at both ends of the rotating shafts, the upper and lower ends of the automatic telescopic rods being detachably connected to two symmetrically arranged trays through connecting rods, a temperature sensor being fixedly connected to the automatic telescopic rod, the temperature sensor temperature measuring probe extending to the middle of the tray, the temperature sensor being communicatively connected to a controller, and the motor being controlled by the controller.

[0005] Furthermore, the support plate is a hollow structure.

[0006] Furthermore, the motor output shaft extends into the support plate and is fixedly connected to a first sprocket, the middle part of the rotating shaft is located in the support plate and is fixedly connected to a second sprocket, the second sprocket is a double-layer wheel, the first sprocket and the second sprocket located at the bottom are connected by a chain transmission, and the two adjacent second sprockets are connected by the chain transmission.

[0007] Furthermore, a protective cover is connected to the tray. The main body of the protective cover is a semicircular structure, and a protective net is provided at one end in the middle of the tray. The temperature sensor probe extends into the interior of the protective cover.

[0008] Furthermore, the controller is communicatively connected to a wireless transceiver module, and the wireless transceiver module is communicatively connected to a mobile terminal.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The utility model connects the automatic telescopic rod through a rotating shaft, and two symmetrically placed trays are arranged at the upper and lower ends of the automatic telescopic rod, so that the fruits can be stored separately, and damage to the fruits caused by long-term accumulation of fruits can be avoided. The trays are driven to rotate by the rotating shaft, and the fruits stored therein are turned over as a whole, so that effective heat dissipation of the heat-prone area in the center of the bottom of the fruit is achieved, and local overheating can be avoided. The automatic telescopic rod is used to adjust the distance between the trays, which ensures that the distance between the two trays is close enough to avoid damage to the fruits when turning over, and ensures that heat dissipation will not be affected by the close distance between the trays during normal storage. The temperature measuring probe of the temperature sensor arranged at the bottom of the tray can realize reliable monitoring of the temperature of the fruit in the tray. At the same time, a semicircular protective cover is provided on the outside of the temperature measuring probe to avoid damage to the fruit in the tray. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 、 Figure 2 、 Figure 3 The shown grape storage rack for refrigeration includes a base 1 and a support plate 2. The base 1 is fixedly connected to the support plate 2. Several rotating shafts 5 are rotatably connected to the support plate 2 and the rotating shafts 5 vertically penetrate the support plate 2. A motor 3 is fixedly connected to the base 1. The motor 3 is transmission-connected to the rotating shaft 5. Automatic telescopic rods 6 are fixedly connected to both ends of the rotating shaft 5. The upper and lower ends of the automatic telescopic rod 6 are detachably connected to two symmetrically arranged trays 7 through connecting rods. A temperature sensor 9 is fixedly connected to the automatic telescopic rod 6. The temperature measuring probe of the temperature sensor 9 extends to the middle of the tray 7. The temperature sensor 9 is communicatively connected to the controller 13, and the motor 3 is controlled by the controller 13.

[0017] In order to facilitate the motor 3 to drive the rotating shafts 5 to rotate and realize the flipping of the pallet, the support plate 2 is a hollow structure, the output shaft of the motor 3 extends into the support plate 2 and is fixedly connected to the first sprocket 10, the middle part of the rotating shaft 5 is located in the plate and is fixedly connected to the second sprocket 11, the second sprocket 11 is a double-layer wheel, the first sprocket 10 and the second sprocket 11 at the bottom are connected by a chain 12, and the two adjacent second sprockets 11 are connected by a chain 12.

[0018] In order to avoid damaging the fruits at the bottom of the tray, a protective cover 8 is connected to the tray 7. The main body of the protective cover 8 is a semicircular structure, and a protective net is covered at one end in the middle of the tray 7. The temperature sensor 9 temperature measuring probe extends into the inside of the protective cover 8.

[0019] In order to improve the automation level of the device, the controller 13 is connected to the wireless transceiver module for communication, and the wireless transceiver module is connected to the mobile terminal for communication.

[0020] The specific working process of this utility model is as follows:

[0021] Arrange the storage racks reasonably inside the cold storage, place the fruits that need to be refrigerated on the tray 7, and use the temperature sensor 9 installed at the bottom of the tray 7 to accurately measure the storage temperature of the bottom center of the fruit and compare it with the standard value. When the system detects that the temperature of the fruit in the tray 7 is higher than the standard value within a certain period of time and the temperature difference reaches the preset value, a warning signal is sent to the mobile terminal through the wireless transceiver module. At the same time, the automatic telescopic rod 6 is shortened, and the motor 3 is started through the controller 13. The motor 3 drives the rotating shaft 5 to rotate through the cooperation of the first sprocket 10, the second sprocket 11 and the chain 12, thereby realizing the overall flipping of the fruit in the tray 7 and achieving effective heat dissipation of the overheated part. After the flip is completed, the motor 3 stops working, the automatic telescopic rod 6 extends, and the temperature sensor 9 continues to monitor in real time. When local overheating is detected again, repeat the above steps.
