[0065] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.

[0066] In order to improve the fresh-keeping performance of the refrigerated container for the goods inside the container, the present invention provides a refrigerated container 100. Figures 4 to 6 As shown, the refrigerated container 100 may include a box body 110, a power supply device 120, a shelf 130, an insulator 170 and a plurality of connectors 160, and the box body 110 may include a door 114, a wall panel 113, a top panel 111 and a bottom panel 112. The door 114, the wall panel 113, the top panel 111 and the bottom panel 112 may all be made of a heat-insulating material to improve the heat-insulating performance of the refrigerated container 100.

[0067] like Figure 4 As shown, the bottom plate 112 is located at the bottom of the box body 110 and may be in a rectangular shape. Figure 6As shown, the wall panel 113 is connected to the door 114 and both the wall panel 113 and the door 114 can extend upward from the upper surface of the bottom plate 112 along the height direction of the refrigerated container 100. In this embodiment, in order to facilitate the storage and retrieval of goods and enhance the fresh-keeping performance of the refrigerated container 100, the wall panel 113 can include a first wall panel, a second wall panel and a third wall panel. The door 114 is located at one end of the refrigerated container 100 and can be a double-door structure. The first wall panel can be located at the other end opposite to the door 114 along the length direction of the refrigerated container 100. The second wall panel and the third wall panel can be located on both sides of the central axis of the length direction of the refrigerated container 100, and the second wall panel and the third wall panel can be connected to the door 114, respectively. Of course, the location and structure of the door 114 and the location and structure of the wall panel 113 are not limited to the cases listed in this embodiment.

[0068] In order to ensure the overall sealing and fresh-keeping performance of the refrigerated container 100, Figure 4 As shown, a power supply device 120 may be further provided outside the box 110 and a refrigeration device 122 may be provided inside the box 110. Both the power supply device 120 and the refrigeration device 122 may be close to the first wall plate of the refrigerated container 100 opposite to the door 114. The refrigeration device 122 may include a refrigerator, which may supply air to the space inside the box 110, thereby reducing the temperature inside the box 110. The shelf 130 may be provided between the door 114 and the refrigeration device 122, so that the refrigeration device 122 may supply air toward the shelf 130, which is beneficial to the air circulation inside the shelf 130 and improves the fresh-keeping performance of the refrigerated container 100.

[0069] Furthermore, in order to better improve the preservation performance of the refrigerated container 100, the shelf 130 can be made of a conductive material, and the power supply device 120 can be electrically connected to the shelf 130. When the power supply device 120 energizes the shelf 130, the shelf 130 can generate a magnetic field of a certain intensity. The physiological metabolism of fresh goods and other goods in the magnetic field is greatly reduced, and food corruption and microbial activities are inhibited. In this way, the refrigerated container 100 can play a very good preservation role for the stored goods. Therefore, the refrigerated container 100 provided in this embodiment adopts the method of combining the refrigeration equipment 122 with the magnetic field, so that the storage time and preservation effect of the goods are greatly improved.

[0070] The shelf 130 can be used to load goods, and the shelf 130 is also arranged inside the box 110. Figures 1 to 6 The specific structure of the shelf 130 will be described.

[0071] like Figure 4 and Figure 5As shown, the shelf 130 may include a bottom frame 138, which is disposed above the bottom plate 112 of the box body 110 and connected to the bottom plate 112, and the goods may be directly placed on the bottom frame 138. The bottom frame 138 includes a bottom cross beam 139, a bottom longitudinal beam 140, and a floor 141. In order to make the bottom frame 138 have a sufficiently large supporting strength, the bottom cross beam 139 and the bottom longitudinal beam 140 may be arranged alternately, and the floor 141 is disposed above the bottom cross beam 139 and the bottom longitudinal beam 140 and connected to the bottom longitudinal beam 140 through a connecting member 160, which may be a bolt, and the goods may be placed on the floor 141. In order to facilitate the circulation of air at the bottom of the goods, the floor 141 may be a track-type floor, such as a T-shaped floor.

[0072] Meanwhile, in order to prevent the electricity from being conducted to the box body 110 of the refrigerated container 100 when the shelf 130 is powered on, the shelf 130 and the box body 110 need to be connected via the insulator 170. The insulator 170 may be made of a high insulation material, such as CPVC (chlorinated polyvinyl chloride). Figure 7 The structure of the connected bottom frame 138 and the bottom plate 112 is shown. An insulator 170 and a connecting plate 180 are provided between the bottom frame 138 and the bottom plate 112. A bottom reinforcing rib may be provided on one side of the bottom longitudinal beam 140. The bottom reinforcing rib may be L-shaped, and one side of the bottom reinforcing rib extending in the height direction of the refrigerated container 100 may be welded to the bottom longitudinal beam 140, and the other side of the bottom reinforcing rib extending in the width direction of the refrigerated container 100 may be connected to the insulator 170.

[0073] In order to enhance the insulation performance, the insulator 170 may include a first insulator 171, a second insulator 172 and a third insulator 173, and the first insulator 171, the second insulator 172 and the third insulator 173 may be stacked in sequence, and a connecting plate 180 is provided between the third insulator 173 and the bottom plate 112. In order to enable the first insulator 171, the second insulator 172 and the third insulator 173 to be stably stacked, a glue 164 may be provided between the first insulator 171 and the second insulator 172, and a glue 164 may be provided between the second insulator 172 and the third insulator 173, so that the first insulator 171, the second insulator 172 and the third insulator 173 can be connected to each other through the glue 164, thereby enhancing stability. The size of the third insulator 173 along the width direction of the refrigerated container 100 may be larger than the size of the first insulator 171 and the second insulator 172, so that the insulator 170 has better insulation performance.

[0074] The bottom reinforcing rib, the first insulator 171, the second insulator 172, the third insulator 173, the connecting plate 180 and the bottom plate 112 may be connected together through the first connecting member 161, the second connecting member 162 and the third connecting member 163 which are not in contact with each other. Specifically, the bottom reinforcing rib may be connected to the first insulator 171 and the second insulator 172 through the first connecting member 161, the second insulator 172, the third insulator 173 and the connecting plate 180 may be connected together through the second connecting member 162, and the connecting plate 180 may be connected to the bottom plate 112 through the third connecting member 163. Since the first insulator 171, the second insulator 172 and the third insulator 173 are stacked, a through hole may be provided in the second insulator 172, and the second connecting member 162 may be connected to the through hole, so that the second connecting member 162 may be connected to the second insulator 172 and the third insulator 173. In order to enhance the insulation performance of the second insulator 172 and enhance the structural strength of the second insulator 172 , glue 164 may be provided around the head of the second connector 162 in the through hole.

[0075] certainly, Figure 7 In the structure shown, glue 164 can be provided between the first insulator 171 and the second insulator 172, between the second insulator 172 and the third insulator 173, and around the head of the second connector 162. In an embodiment not shown in the figure, glue can be provided between the first insulator and the second insulator and / or around the head of the second connector, or glue can be provided between the second insulator and the third insulator and around the head of the second connector.

[0076] In order to enhance the connection strength between the connecting plate 180 and the bottom plate 112, the connecting plate 180 may be a steel plate, and the third connecting member 163 may be a screw, which may directly screw the steel plate and the bottom plate 112 together, thereby making the connection between the connecting plate 180 and the bottom plate 112 more secure.

[0077] In an embodiment not shown in the figure, an insulator may be provided between the shelf and the box, and the shelf, the insulator and the bottom plate may be connected by connectors. The connector may include a first connector and a second connector that are spaced apart, and the shelf may be connected to the insulator via the first connector, and the insulator may be connected to the box via the second connector. In this way, since an insulator is provided between the shelf and the box, and the first connector and the second connector are spaced apart, the electricity of the shelf will not be conducted to the box, thereby avoiding danger.

[0078] Furthermore, in order to more firmly fix the goods to the shelf 130, as Figure 1 and Figure 2As shown, the shelf 130 may also include at least two vertical beams and a cross beam. The vertical beam may extend upward from the upper surface of the bottom frame 138 along the height direction of the refrigerated container 100, and the cross beam is used to connect at least two vertical beams. The cross beam may be connected to the top of the vertical beam so that the interior of the shelf 130 has a sufficiently large accommodation space.

[0079] Specifically, Figure 1 As shown, the vertical beam may include a first side vertical beam 133 and a second side vertical beam 134. The first side vertical beam 133 may be close to the door 114, and the second side vertical beam 134 may be far away from the door 114. The top of the first side vertical beam 133 and the top of the second side vertical beam 134 may be connected by a side cross beam 132. The bottom of the first side vertical beam 133 is connected to the bottom frame 138, and the bottom of the second side vertical beam 134 is connected to the bottom frame 138.

[0080] In order to facilitate ventilation and preservation and generate a magnetic field by powering on, a ventilation device can be provided in the frame formed between the first side vertical beam 133, the second side vertical beam 134, the side cross beam 132 and the bottom frame 138. The ventilation device can be a side louver 145a for side ventilation. Furthermore, in order to enable the goods to be stably connected to the shelf 130, a tying beam 151 is provided between the first side vertical beam 133, the second side vertical beam 134, the side cross beam 132 and the bottom frame 138. The tying beam 151 can be connected to each vertical beam and cross beam through a connecting piece 160, and the goods can be fixed to the tying beam 151. The tying beam 151 and the side louver 145a are arranged alternately, so that the interior of the shelf 130 can be sufficiently ventilated.

[0081] Furthermore, if Figure 2 As shown, the vertical beams may further include a first end vertical beam 135 and a second end vertical beam 136. The first end vertical beam 135 and the second end vertical beam 136 may be arranged opposite to each other along the width direction of the container. The second side vertical beam 134 and the first end vertical beam 135 may be connected together by a connecting member 160 (eg, Figure 6 The top of the first end beam 135 and the top of the second end beam 136 may be connected via an end cross beam 137, the bottom of the first end beam 135 is connected to a bottom frame 138, and the bottom of the second end beam 136 is connected to the bottom frame 138.

[0082] In order to facilitate ventilation and preservation and generate a magnetic field by powering on, a ventilation device may be provided in the frame formed between the first end beam 135, the second end beam 136, the end cross beam 137 and the bottom frame 138, and the ventilation device includes an end louver 145b and an air supply port 190 for ventilation of the end surface. The end louver 145b may be connected to the first end beam 135, the second end beam 136 and the end cross beam 137 respectively through a connecting member 160. The air supply port 190 may be located close to the refrigeration equipment 122 and may be connected to the bottom frame 138 through a connecting member 160, and the cold air generated by the refrigeration equipment 122 may enter the interior of the shelf 130 through the air supply port 190. Furthermore, in order to facilitate the maintenance of the refrigeration equipment 122, an inspection window 147 may be provided between the first end beam 135, the second end beam 136, the end cross beam 137 and the bottom frame 138. The inspection window 147 may include an openable window, which may be connected to the vertical beam via a hinge 148 and may be provided with a lock 149 to protect the refrigeration equipment 122 .

[0083] To secure high-altitude cargo, such as Figure 4 As shown, the top of the vertical beam and / or the cross beam may also be provided with a tying ring 152, and there may be multiple tying rings 152 for tying goods. The tying ring 152 may be connected to the top of the vertical beam and / or the cross beam by welding. In order to make it easier to tie the goods to the tying ring 152, a top beam 131 is provided on one side of the top of the vertical beam facing the inner side of the refrigerated container 100, as shown in FIG. Figure 1 As shown, the top beam 131 can be connected to the side beams 132 / end beams 137 through a connector 160, or can be directly welded to the side beams 132 / end beams 137. A tying ring 152 can also be provided on the top beam 131.

[0084] Furthermore, if Figure 3 As shown, an openable door 142 is provided at one end of the shelf 130 along the length direction of the refrigerated container 100 near the door 114. The door 142 includes a door panel 143 and a door reinforcement rib 144 for increasing the strength of the door panel 143. The top of the door panel 143 may be close to the top beam 131 of the shelf 130. In order to ensure the safety of the staff when opening the door 114 of the refrigerated container 100 and the door 142 of the shelf 130, as shown in FIG. Figure 6 As shown, the refrigerated container 100 further includes a control device, which may be disposed on the shelf 130 .

[0085] Specifically, the control device 146 may include a first contact 191 and a second contact 192, the first contact 191 may be arranged on the top beam 131 of the shelf 130, the second contact 192 may be arranged on the inner side of the door 114 facing the refrigerated container 100, and the first contact 191 and the second contact 192 are opposite to each other. The door panel 143 may be fixed to the door 114. When the door 114 is in a closed state, the first contact 191 and the second contact 192 are in contact, the power supply device 120 supplies power to the shelf 130, and the shelf 130 is in a powered state to generate a magnetic field. When the staff opens the door 114, the door 114 can drive the door panel 143 to rotate so that the door 114 and the door panel 143 are in an open state, the first contact 191 and the second contact 192 can be separated, and the shelf 130 is in a powered-off state, thereby preventing accidental electric shock when the personnel enter the box, and ensuring the safety of the personnel.

[0086] In order to prevent the electricity of the rack 130 in the powered state from being conducted to the box 110, Figure 6 and Figure 8 As shown, each vertical beam and cross beam of the shelf 130 is connected to each wall panel 113 and the door 114 via an insulator 170. The vertical beam in the figure can be any one of the first side vertical beam 133, the second side vertical beam 134, the side cross beam 132, the first end vertical beam 135, the second end vertical beam 136, the end cross beam 137 and the door 142. The second side vertical beam 134 is now taken as an example for explanation. The wall panel 113 can be a second wall panel and a third wall panel respectively located on both sides of the central axis of the length direction of the refrigerated container 100, or can be a first wall panel at one end of the refrigerated container 100 relative to the door 114 along the length direction of the refrigerated container 100. The wall panel 113 close to the second side vertical beam 134 is now taken as an example for explanation. The connection structure between the second side vertical beam 134 and the wall panel 113 is similar to the connection structure between the bottom frame 138 and the bottom plate 112.

[0087] Specifically, the insulator 170 may include a first insulator 171, a second insulator 172, and a third insulator 173, which may be stacked in sequence, and a connecting plate 180 may be provided between the third insulator 173 and the wall plate 113. In order to stably stack the first insulator 171, the second insulator 172, and the third insulator 173, a glue 164 may be provided between the first insulator 171 and the second insulator 172, and a glue 164 may be provided between the second insulator 172 and the third insulator 173, so that the first insulator 171, the second insulator 172, and the third insulator 173 can be connected to each other through the glue 164, thereby enhancing stability. The size of the third insulator 173 along the length direction of the refrigerated container 100 may be larger than the size of the first insulator 171 and the second insulator 172, so as to have better insulation performance.

[0088] The second side beam 134, the first insulator 171, the second insulator 172, the third insulator 173, the connecting plate 180 and the wall plate 113 can be connected together through the first connecting member 161, the second connecting member 162 and the third connecting member 163 which are not in contact with each other. Specifically, the second side beam 134 can be connected with the first insulator 171 and the second insulator 172 through the first connecting member 161, the second insulator 172, the third insulator 173 and the connecting plate 180 can be connected together through the second connecting member 162, and the connecting plate 180 can be connected with the wall plate 113 through the third connecting member 163. Since the first insulator 171, the second insulator 172 and the third insulator 173 are stacked, a through hole can be provided in the second insulator 172, and the second connecting member 162 can be connected to the through hole, so that the second connecting member 162 can be connected with the second insulator 172 and the third insulator 173. In order to enhance the insulation performance of the second insulator 172 and enhance the structural strength of the second insulator 172 , glue 164 may be provided around the head of the second connector 162 in the through hole.

[0089] certainly, Figure 8 In the structure shown, glue 164 can be provided between the first insulator 171 and the second insulator 172, between the second insulator 172 and the third insulator 173, and around the head of the second connector 162. In an embodiment not shown in the figure, glue can be provided between the first insulator and the second insulator and / or around the head of the second connector, or glue can be provided between the second insulator and the third insulator and around the head of the second connector.

[0090] In order to enhance the connection strength between the connecting plate 180 and the wall panel 113, the connecting plate 180 may be a steel plate, and the third connecting member 163 may be a screw, which may directly screw the steel plate and the wall panel 113 together, thereby making the connection between the connecting plate 180 and the wall panel 113 more secure.

[0091] According to a refrigerated container 100 provided by the present invention, a shelf 130 is arranged inside the box body 110 of the refrigerated container 100, and the shelf 130 is electrically connected to the power supply device 120.
