Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment, and in particular to a photovoltaic-based mobile cold storage. Background Art

[0002] Due to the large size and weight of cold storage, most of the cold storage on the market currently adopts a fixed installation method. If the cold storage needs to be moved, it can only be completely dismantled and reassembled; there will inevitably be a large number of loss parts during the disassembly process, and the sealing performance of the reassembled cold storage body will be lower than that of the original cold storage. The mobile cold storage on the market is generally smaller in size, or more accurately, a larger freezer; in order to facilitate disassembly and transportation, the current mobile cold storage body is mostly installed with an assembled structure, which seriously affects the overall sealing and thermal insulation of the cold storage.

[0003] Chinese patent CN216924878U discloses a mobile cold storage, including a chassis, a storage body and a roller unit, the chassis is spaced apart from the ground, the storage body is fixed on the chassis, a plurality of roller units are arranged on the end surface of the chassis facing the ground, each roller unit is spaced apart, the plurality of roller units include a plurality of first units and at least one second unit, the plurality of first units are evenly arranged on the chassis along the edge of the end surface of the chassis, and each second unit is arranged in the middle of the chassis and away from the edge of the chassis.

[0004] The above scheme ensures the overall sealing and thermal insulation of the cold storage, making it easy to move and transport the cold storage through the roller unit. However, when loading and unloading items in the cold storage, the door of the cold storage still needs to be opened for staff to enter and take items, which will cause the cold air in the cold storage to overflow, so that the refrigeration equipment needs to prepare cold air again, increasing power consumption. In the prior art, it is usually necessary to extract the cold air in the cold storage in advance, but after the cold air in the cold storage is extracted, new air needs to be replenished, which will cause the cold air inside the cold storage to mix with the replenished air, thereby neutralizing the temperature of the cold air. Even if the collected cold air is released again in time, the effect is very poor, and the temperature in the cold storage still needs to be cooled again. Summary of the invention

[0005] In view of the above problems, a photovoltaic-based mobile cold storage is provided, in which storage bins arranged on both sides of an inner bin can store items. When a staff member needs to enter the outer shell to take out items, a mobile device drives the inner bin to move toward the second opening, so that the inner bin will move to one side of the second opening driven by the mobile device, and the first gear will engage with the second gear, and then the first rotary drive drives the second gear to rotate. Since the second gear and the first gear engage with each other, the first gear will also rotate after the second gear rotates, so that the first bin door and the second bin door will open synchronously, and since the side wall of the inner bin is in close contact with the inner wall of the outer shell, it is ensured that the cold air in the outer shell will not overflow. After the staff member enters the inner bin, the first rotary drive drives the first gear to rotate in the opposite direction through the second gear, the first bin door and the second bin door are closed, and the mobile device is activated again, ensuring that the cold air in the outer shell will not overflow while maintaining the initial temperature.

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] Reference Figure 1-Figure 4: A photovoltaic-based mobile cold storage comprises a shell 1, a photovoltaic panel and a sealing device 2; the sealing device 2 comprises an inner bin 21, a first gear 211, a first bin door 212, a moving device 22, a second gear 23, a second bin door 24 and a first rotating driver 25; the shell 1 is a rectangular structure, the inner bin 21 is movably arranged inside the shell 1 along the length direction of the shell 1, a first opening is opened on one side of the shell 1, a plurality of storage bins are arranged inside the shell 1, and the plurality of storage bins are symmetrically arranged about the inner bin 21 along the length direction of the shell 1; the first gear 211 is rotatably arranged on one side of the first opening; the first bin door 212 is fixedly arranged on one side of the first gear 211, and the first bin door 2 12 can be driven by the first gear 211 to rotate along the axis of the first gear 211, and the first compartment door 212 is arranged in the first opening; a second opening is opened on one side of the outer shell 1, and the second gear 23 is rotatably arranged on one side of the second opening, and the first gear 211 can mesh with the second gear 23; the second compartment door 24 is fixedly arranged on one side of the second gear 23, and the second compartment door 24 is arranged in the second opening; the moving device 22 is arranged at the bottom of the inner compartment 21, and the moving device 22 can drive the inner compartment 21 to move along the length direction of the outer shell 1; the first rotation driver 25 is fixedly arranged at the lower part of the second gear 23, and the first rotation driver 25 can drive the second gear 23 to rotate.

[0041] A photovoltaic panel is provided on the top of the outer shell 1, and the storage bin is used to store items. When the items in the storage bin need to be taken out, the moving device 22 drives the inner bin 21 to move to the side of the outer shell 1 where the second opening is provided. At this time, the first gear 211 and the second gear 23 are in a meshing state, so that when the second gear 23 rotates, the first gear 211 will also rotate synchronously, and then the first rotation driver 25 is started, and the first rotation driver 25 drives the second gear 23 provided on its output end to rotate, so that the first gear 211 will also be driven to rotate. Since the first bin door 212 is fixedly provided on one side of the first gear 211, and the second bin door 24 is fixedly provided on one side of the second gear 23, after the first gear 211 and the second gear 23 rotate, the first bin door 212 and the second bin door 24 will rotate, and then the staff can enter the inner bin 21. After confirming that no one is in the entry state, the staff can take out the first bin door 212 and the second bin door 24. A rotary driver 25 is activated again, the first rotary driver 25 drives the second gear 23 to rotate in the opposite direction, and the second gear 23 also drives the first gear 211 to rotate in the opposite direction, and the first bin door 212 and the second bin door 24 will be closed. Then the staff can drive the inner bin 21 to slide inside the outer shell 1 through the moving device 22. A retrieval slot is provided on the side of the inner bin 21 close to the storage bin, and the staff can take out the items in the storage bin through the retrieval slot. Since the first gear 211 is set on the inner bin 21, when the moving device 22 drives the inner bin 21 to move, the first gear 211 and the second gear 23 are disengaged. Only when the moving device 22 drives the inner bin 21 to move to the side of the outer shell 1 where the second opening is provided, the first gear 211 and the second gear 23 will be engaged. By setting the inner bin 21, the cold air in the outer shell 1 is isolated from the second opening, ensuring that the cold air in the outer shell 1 can maintain the initial temperature while not overflowing.

[0042] Reference Figure 2 and Figure 5 The moving device 22 includes a driving device 221, a synchronous wheel 222, a synchronous belt 223 and a protrusion 224; two synchronous wheels 222 are provided, and the two synchronous wheels 222 are arranged along the length direction of the outer shell 1, and the synchronous wheels 222 are rotatably arranged below the inner warehouse 21; the synchronous belt 223 is sleeved on the two synchronous wheels 222, and the synchronous belt 223 and the synchronous wheels 222 are transmission-matched; the protrusion 224 is fixedly arranged at the bottom of the inner warehouse 21, and a snap-in groove is opened on the synchronous belt 223, and the protrusion 224 is snap-fitted with the snap-in groove; the driving device 221 is arranged on one side of the synchronous wheel 222, and the driving device 221 can drive the synchronous wheel 222 to rotate.

[0043] When the driving device 221 is started, the synchronous wheel 222 will be driven to rotate by the driving device 221. Since the synchronous wheel 222 and the synchronous belt 223 are in transmission cooperation, the synchronous belt 223 will be driven to rotate by the synchronous wheel 222. Since the synchronous belt 223 is provided with a snap-in groove, and the snap-in groove is engaged with the protrusion 224, after the synchronous belt 223 rotates, the inner warehouse 21 can be driven to move by the synchronous belt 223.

[0044] Reference Figure 8 and Fig.10 The sealing device 2 also includes a sealing component 26, which includes a sealing ring 261, a trigger rod 262, a spring 263 and an electromagnet 264; the sealing ring 261 is arranged around the first compartment door 212 on a side of the inner compartment 21 where the first compartment door 212 is arranged; a groove is provided on the side where the first opening is provided in the inner compartment 21, and the trigger rod 262 can be slidably arranged in the groove along the depth direction of the groove, a trigger groove is provided at the bottom of the groove, and a conductive material is provided on the groove wall of the trigger groove, and the trigger rod 262 can slide with the trigger groove, a limit ring is provided on the trigger rod 262, and there is a gap between the limit ring and the bottom of the groove, and a contact is provided on the inner wall of the shell 1, and the contact can pass the current to the conductive material in the trigger groove through the trigger rod 262; the spring 263 is provided in the gap; the electromagnet 264 is provided on one side of the sealing ring 261, and a controller is provided in the inner compartment 21, and the trigger rod 262 controls the operation of the electromagnet 264 through the controller.

[0045] In order to ensure the sealing performance, when the moving device 22 drives the inner warehouse 21 to move to the side of the outer shell 1 where the second opening is opened, the trigger rod 262 on one side of the inner warehouse 21 will contact the inner wall of the outer shell 1, and the trigger rod 262 will contact the contact arranged on the inner wall of the outer shell 1. Since the contact is in a powered state, when the trigger rod 262 contacts the contact, the trigger rod 262 will also be energized. As the moving device 22 drives the inner warehouse 21 to continue to move, the trigger rod 262 will slide and cooperate with the trigger groove, and the spring 263 will be in a compressed state, so that the controller is turned on, and the controller energizes the electromagnet 264, and the electromagnet 264 generates an attraction to the inner wall of the outer shell 1. In this way, the inner wall of the outer shell 1 and the inner warehouse 21 will squeeze the sealing ring 261. Under the action of the sealing ring 261, the cold air in the outer shell 1 is not easy to overflow. The spring 263 arranged on the periphery of the trigger rod 262 can ensure that the trigger rod 262 and the trigger groove are disengaged when the inner warehouse 21 leaves the second opening side.

[0046] Reference Figure 8 and Fig.10 The sealing assembly 26 further includes an insulating sleeve 265; the insulating sleeve 265 is disposed in the gap along the axis of the trigger rod 262, and the insulating sleeve 265 is located between the spring 263 and the trigger rod 262.

[0047] When the insulating sleeve 265 is not provided, when the spring 263 is compressed, the spring 263 is easily energized by the trigger rod 262, and the energized spring 263 will heat the trigger rod 262. In order to avoid the above situation, the insulating sleeve 265 is provided between the spring 263 and the trigger rod 262.

[0048] Reference Figure 5 and Figure 6 The driving device 221 includes a second rotation driver 2211, a gear ring 2212 and a third gear 2213; the second rotation driver 2211 is horizontally arranged on one side of the synchronous wheel 222; the third gear 2213 is fixedly arranged on the output end of the second rotation driver 2211; the gear ring 2212 is arranged on one side of the third gear 2213, the gear ring 2212 and the third gear 2213 are meshed with each other, the axis of the gear ring 2212 is colinear with the axis of the synchronous wheel 222, and the gear ring 2212 can drive the synchronous wheel 222 to rotate.

[0049] The second rotation driver 2211 is preferably a servo motor. When the synchronous wheel 222 is driven to rotate, the second rotation driver 2211 will start, and the second rotation driver 2211 drives the third gear 2213 arranged on its output end to rotate. Since the third gear 2213 and the gear ring 2212 are engaged with each other, when the third gear 2213 rotates, the gear ring 2212 will also be driven to rotate. It is worth noting that the diameter of the third gear 2213 needs to be smaller than the diameter of the gear ring 2212, so that the load of the initial operation of the second rotation driver 2211 can be reduced.

[0050] Reference Figure 5 and Figure 6 : The mobile device 22 also includes a safety component 225, which includes a rotating rod 2251 and a button 2252; one end of the rotating rod 2251 is fixedly arranged on the output end of the first rotation driver 25; two buttons 2252 are provided, and the two buttons 2252 are arranged around the axis of the rotating rod 2251.

[0051] When the first rotary driver 25 is started, the rotating rod 2251 will rotate synchronously with the output end of the first rotary driver 25. When the first compartment door 212 is in a fully open state and a closed state, the rotating rod 2251 will trigger the two buttons 2252 respectively. The triggered buttons 2252 will cut off the power of the first rotary driver 25, thereby ensuring the accuracy of opening and closing the first compartment door 212 and the second compartment door 24.

[0052] Reference Figure 5 and Figure 7: The moving device 22 also includes a support assembly 226, and the support assembly 226 includes a support plate 2261 and a roller 2262; the support plate 2261 is arranged in the ring of the synchronous belt 223, and the support plate 2261 is used to provide support for the synchronous belt 223; a plurality of rollers 2262 are provided, and the rollers 2262 are evenly arranged along the length direction of the support plate 2261.

[0053] When the moving device 22 drives the inner warehouse 21 to move, the weight of the inner warehouse 21 will act on the synchronous belt 223. If the synchronous belt 223 has no support, it will inevitably sink. In order to avoid the above situation, a support plate 2261 can be set under the synchronous belt 223 to provide support for the synchronous belt 223. At the same time, multiple rollers 2262 are set on the support plate 2261 to reduce the friction between the synchronous belt 223 and the support plate 2261.

[0054] Reference Figure 2 and Figure 3 The sealing device 2 also includes a ventilation component 214, which includes an air pipe 2141 and a fan 2142; the fan 2142 is arranged on one side of the outer shell 1; the two ends of the air pipe 2141 are respectively connected to the fan 2142 and the inner chamber 21.

[0055] After the staff enters the outer shell 1, the second compartment door 24 will be completely closed. In order to provide sufficient oxygen into the inner compartment 21, the fan 2142 will be started at this time. The fan 2142 blows air into the inner compartment 21 through the air pipe 2141. At the same time, an oxygen concentration sensor is provided in the inner compartment 21. When the oxygen concentration sensor detects that the oxygen concentration is lower than a certain value, the moving device 22 will drive the inner compartment 21 to move toward the second opening of the outer shell 1, and at the same time activate the first rotary drive 25. Under the action of the first rotary drive 25, the first compartment door 212 and the second compartment door 24 can be opened synchronously, thereby ensuring the life safety of the staff.

[0056] Reference Fig. 9 The sealing device 2 further includes a switch door 213; a plurality of switch doors 213 are provided, and the plurality of switch doors 213 are uniformly arranged along the height direction of the inner warehouse 21 on one side of the inner warehouse 21 close to the storage warehouse.

[0057] By providing the switch door 213 , the sealing of the inner compartment 21 can be ensured after the items are taken out, thereby preventing the cold air in the outer shell 1 from overflowing from the inner compartment 21 .

[0058] Reference Figure 2 : The sealing device 2 also includes a circulation pipe 27 and a partition 271; the partition 271 is arranged on the upper part of the inner warehouse 21; the circulation pipe 27 is arranged on the upper part of the partition 271 along the length direction of the outer shell 1.

[0059] When the inner compartment 21 moves, the air in the outer shell 1 will be squeezed by the inner compartment 21 , that is, the inner compartment 21 will divide the space in the outer shell 1 into two parts. The circulation pipe 27 is provided to ensure that the air in the two parts circulates with each other.

[0060] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
