As shown in fig. 1 and 2, in one embodiment, a thermal insulation system 10 for a retractable loading and unloading cargo platform of a refrigerator is provided, which mainly comprises an outer wall 11 enclosing the refrigerator, wherein a low-temperature environment can be formed in a space enclosed by the outer wall 11 through a refrigeration system for storing cargo.

Further, as shown in fig. 2, the refrigeration house retractable loading and unloading cargo platform thermal insulation system 10 further includes a door 12. The outer wall 11 is provided with an opening 112, and as shown in fig. 3, the door leaf 12 is disposed at the opening 112. When the goods are not required to be loaded or unloaded, the door 12 is closed, and the cold in the refrigerator is stored in the refrigerator in a sealed manner. When cargo is to be loaded or unloaded, the door leaf 12 is opened, and the cargo in the container is sent into or out of the refrigerator through the opening 112.

As shown in fig. 2 and 3, a first heat insulating layer 14 and a protective layer 15 are sequentially stacked inside the outer wall 11 enclosing the refrigerator. The arrangement of the first heat preservation layer 14 improves the heat preservation effect of the refrigeration house, and the protective layer 15 plays a certain protection role in the heat preservation layer. The opening 112 is further provided with a door frame 13 and a door leaf sealing rubber strip 131 which are connected with each other, the door frame 13 is connected with the outer wall body 11, the door leaf sealing rubber strip 131 is tightly abutted against the door leaf 12, the side edge of the door frame 13 connected with the door leaf sealing rubber strip 131 is a partition sealing edge, a fracture is arranged on the protective layer 15 at the position contacting with the partition sealing edge, and the fracture divides the protective layer 15 into two parts which are mutually disconnected. Namely, the part of the protective layer 15, which is positioned in the cold storage, and the part of the protective layer, which is positioned outside the cold storage, are separated, so that the cold quantity in the cold storage is effectively prevented from being transmitted to the outside through the protective layer 15, the cold bridge at the door leaf 12 of the cold storage is prevented from occurring, the heat preservation effect of the cold storage is improved, the energy consumption is reduced, and the generation of condensed water is reduced. Thus, when the door 12 is closed, the inside of the refrigerator room is isolated from the outside.

Specifically, the door 12 can be provided with a door insulating layer and a sealing rubber strip, so that the heat insulating effect of the refrigeration house is further improved. When the door leaf 12 is in a closed state, as shown in fig. 2 and fig. 6, each edge of the door leaf 12 is in interference sealing with the door leaf sealing rubber strip 131 or the outer wall 11. And a closed space is formed, and the cold energy in the refrigeration house is stored in the closed space.

As shown in fig. 6 and 7, the first heat insulating layer 14 and the protective layer 15 may be disposed on the outer wall 11 above the opening 112, and when the door 12 is closed, the top end of the door 12 is sealed against the protective layer 15. And a fracture is also arranged on the protective layer 15, and when the door leaf 12 is closed, the position on the protective layer 15, which is in contact with and sealed with the door leaf 12, is the position where the fracture is arranged. Therefore, temperature transmission does not exist between the two parts of the protective layer 15 divided by the partition openings, and the cold energy in the refrigeration house is effectively prevented from being transmitted to the outside through the protective layer 15.

Further, in one embodiment, as shown in fig. 3 and 7, the weather-resistant sealant 16 can be disposed in the separation corresponding to the sealing edge of the partition or in the separation corresponding to the protective layer 15 on the outer wall 11 above the opening 112.

Not only the continuity and the strength of the protective layer 15 are ensured, but also the purpose of improving the heat preservation effect of the refrigeration house is achieved. And the weather-resistant sealant 16 can bear a low-temperature environment, and the sealing performance in the low-temperature environment is guaranteed.

Furthermore, a keel is arranged on the outer wall body 11, the protective layer 15 is connected with the keel through a screw, and the first heat-insulating layer 14 is formed between the protective layer 15 and the outer wall body 11 through secondary bubble filling. The shape enclosed by the protective layer 15 is the same as the shape enclosed by the outer wall 11. Here, the outer wall 11 is a structural layer that forms the closed space of the refrigerator together with the ground. For example, the exterior wall 11 may include peripheral side walls and a top wall. And the opening 112 may be provided on the sidewall.

Specifically, the door 12 is a lifting door. In order to improve the sealing performance, a groove 121 may be formed on the floor of the refrigerator, and when the door 12 is closed, the door 12 is lowered to be in interference sealing with the bottom surface of the groove 121.

Alternatively, the door leaf 12 may be configured as a door body structure with other opening forms, and is not limited in particular here. For example, the door leaf 12 can be moved to the left or right to open or close the opening 112 when space permits.

Further, in one embodiment, as shown in fig. 2 and 3, the surface of the outer wall 11 surrounding the opening 112 is an opening sidewall 1121. Specifically, the opening sidewall 1121 may include two opposite left and right sidewalls and a top wall. The first thermal insulation layer 14 and the protective layer 15 both extend from the inner side of the outer wall 11 to the opening side wall 1121, and a weather-resistant sealant 16 is disposed between an end portion of the protective layer 15 extending to the opening side wall 1121 and the outer wall 11.

It is assumed that the two portions of the protective layer 15 divided by the interruption are defined as a first portion and a second portion, the first portion being located outside the interruption. The first portion extends to the opening sidewall 1121, and a weather-resistant sealant 16 is disposed between an end of the first portion extending to the opening sidewall 1121 and the outer wall 11. Thereby further avoiding that a small amount of the cold transferred to the first part is transferred to the outside via the outer wall 11. Avoiding the formation of cold bridges at the openings 112.

Similarly, as shown in fig. 6 and fig. 7, the protective layer 15 above the opening 112 also extends to the opening sidewall 1121 above the opening 112, and a weather-resistant sealant 16 may also be disposed between the end of the upper protective layer 15 extending to the opening sidewall 1121 and the outer wall 11.

In order to achieve the purpose of energy conservation and consumption reduction, the refrigeration house and the outdoor are isolated and insulated as much as possible, and the cold quantity in the refrigeration house is prevented from leaking. Particularly, in the process of loading and unloading goods, the door leaf 12 of the refrigeration house needs to be opened, and how to avoid the leakage of cold energy in the process is very important.

Thus, as further shown in fig. 2, in one embodiment, the exterior wall 11 is provided with a door seal 17 on the outside at the opening 112. The door seal 17 is used for isolating and preserving heat, and further prevents cold in the cold storage from being transmitted to the outside after the door leaf 12 is opened. Specifically, the size of the entrance of the dock seal 17 matches the size of the container, and when the container is withdrawn into the dock seal 17, the container collides with the sidewall of the entrance of the dock seal 17.

In the process of loading and unloading goods, after the container retreats into the door seal 17, the container can collide with the door seal 17, and even if the door leaf 12 of the refrigeration house or the door of the container is opened, the cold quantity in the refrigeration house can be blocked in the refrigeration house, so that the aim of heat preservation of the refrigeration house in the loading and unloading process is fulfilled.

Further, in one embodiment, as shown in fig. 1 and 2, in order to prevent the leakage of the cooling capacity in the refrigerator as much as possible. The freezer is further provided with a pass-through area 111 as a transition area for loading and unloading goods. Generally, the temperature of the hall region 111 is still low relative to the outdoor environment, and there is a certain temperature difference with the outdoor environment.

Further, as shown in fig. 1 and 2, in one embodiment, a foundation ditch 1111 is formed on the ground of the hall penetrating region 111, and the foundation ditch 1111 is correspondingly communicated with the opening 112. The foundation ditch 1111 mainly is used for arranging lifting equipment to adapt to cargo loading and unloading of containers with different heights. When the container is opposite to the foundation pit 1111 through the opening 112, the lifting device in the foundation pit 1111 can be adjusted to a proper height so as to carry the goods.

As shown in fig. 2, 4, 5 and 6, the ground of the parade region 111 is provided with a parade insulating layer 113, the side wall and the bottom wall of the foundation pit 1111 are provided with a foundation pit insulating layer 114, and the foundation pit insulating layer 114 is connected with the parade insulating layer 113 to form a second insulating layer.

Namely, a foundation pit insulating layer 114 is arranged in the foundation pit 1111, and the foundation pit insulating layer 114 is connected with the penetrating insulation layer 113 to form a complete insulating layer, so that the heat insulation in the refrigeration house is uninterrupted. Thereby avoiding the occurrence of a cold bridge in the through-hole area 111 caused by the arrangement of the foundation pit 1111. Namely, the foundation pit insulation layer 114 connected with the penetrating insulation layer 113 ensures the heat preservation capability at the foundation pit 1111. The whole ground of the hall penetrating area 111 is paved with the heat insulation layer, and the cold energy cannot be conducted out from the ground of the hall penetrating area 111.

Specifically, as shown in fig. 8, in one embodiment, the second insulating layer is disposed in a wall of the foundation pit corresponding to the through-hall area. The second heat-insulating layer comprises a steam-insulating film 118, an extruded polystyrene board 117, a waterproof ventilated film 116 and geotextile 115 which are sequentially stacked in the direction from bottom to top.

As shown in fig. 5, the thickness L1 of the foundation pit insulation layer 114 disposed in the bottom wall of the foundation pit 1111 is 50, the thickness L2 of the outer wall located inside the foundation pit insulation layer 114 is 70, and the thickness L3 of the outer wall located outside the foundation pit insulation layer 114 is 180.

Further, as shown in fig. 1 and 2, in one embodiment, the foundation pit 1111 includes a body region 1112 and an auxiliary region 1113 which are connected to each other. The body region 1112 is used for mounting a lifting device, and the body region 1112 is communicated with the opening 112. The number of the auxiliary regions 1113 is two, the two auxiliary regions 1113 are respectively located at two sides of the body region 1112, and the auxiliary regions 1113 are located at one end of the body region 1112 close to the opening 112. The side wall of the auxiliary area 1113 farthest from the other auxiliary area 1113 is an outer side wall, the distance between the two outer side walls is H, and H is larger than the width of a cabinet door of the container truck and is used for accommodating the cabinet door of the container truck with the door opening angle larger than 90 degrees to form a basically continuous unloading chain of the container truck.

During loading and unloading of goods, the door leaf 12 is opened first, and the container is then partly retracted into the foundation pit 1111, so that the container doors are located between the auxiliary areas 1113. The container door is opened after the container car has seated on the crash pad 18 at the opening 112, and the auxiliary area 1113 is provided to provide room for the opening of the container door. Thereby ensuring that the goods are always in a lower temperature environment. Need not to open the packing cupboard cabinet door in advance, avoid the condition of cold volume loss to take place.

In particular, when the door seal 17 is provided on the outside of the outer wall 11, the container door does not have to be opened before the container is withdrawn into the opening 112. The door leaf 12 can be opened only when the container is withdrawn between the door seal 17 and the opening 112, and then the container door is opened after the container door has been withdrawn into the opening 112. Thereby the freezer is in the isolated state with the external world all the time in whole process.

Of course, alternatively, if the cabinet door of the container is opened by ascending and descending, the auxiliary area 1113 may not be used. Especially, when the door 12 is a lifting door, the space of the refrigerator in the height direction is generally enough for the lifting and opening process of the cabinet door.

However, the auxiliary area 1113 satisfies the form that the doors of the cargo container are opened towards the left and right sides, and the application range of the refrigeration storage telescopic loading and unloading cargo platform heat preservation system 10 is widened.

Further, in one embodiment, as shown in fig. 1 and 2, the outer side of the outer wall 11 at the opening 112 is provided with a crash pad 18 for preventing the container truck from directly hitting the outer wall 11, and the crash pad 18 can move up and down relative to the outer wall 11.

Based on the foundation ditch 1111 includes the main body area 1112 and the auxiliary area 1113, the auxiliary area 1113 is located on both sides of the main body area 1112, that is, the ground height of the position of the outer wall 11 corresponding to the auxiliary area 1113 is low, during the process of loading and unloading goods, if a vehicle collides with the outer wall 11 outside the auxiliary area 1113, the impact force that the outer wall 11 needs to bear is large without the supporting function of the ground with equal height, and there is a risk of collision. Based on this, the crash pad 18 is arranged on the outer side of the opening 112 of the outer wall 11, and the crash pad 18 can move up and down relative to the outer wall 11, so that the crash pad 18 can adjust the bottom end of the foundation pit bottom structural plate located on the inner side of the outer wall 11, and the top end of the crash pad 18 is located on the foundation pit outer side structural wall. When the anti-collision pad 18 is impacted, the impact force can be transmitted to the foundation pit bottom structural plate, the outer wall body 11 is prevented from being completely borne by the foundation pit outer side structural wall, namely the outside of the foundation pit, and the impact resistance is improved.

Further, as shown in fig. 1 and 2, in one embodiment, the crash pad 18 is disposed on both left and right sides of the opening 112. Further improving the stability during impact.

And based on the crashproof pad 18 is adjustable in the position on the outer wall body, can adjust the position of crashproof pad 18 according to the different height dimensions of container car to the demand that adapts to different packing cupboard loading and unloading goods. The position of the crash pad 18 may be adjusted manually or automatically by a control system. For example, a positioning device is provided on the vehicle carrying the container, and when the container approaches, the crash pad 18 automatically adjusts to the proper position by sensing the position of the positioning device.

Further, in an embodiment, the door 12 is a lifting door, as shown in fig. 1, a groove 121 disposed on the ground of the freezer is located at one end of the auxiliary area 1113 close to the opening 112, the lifting door can be lowered to interfere with a bottom wall of the groove 121, and when the lifting door is closed, the lifting door interferes with the door frame for sealing.

When the door leaf 12 is closed, the door leaf 12 extends below the floor of the auxiliary area 1113, so that the cold in the halling area 111 is effectively isolated.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
