Description

Technical Field

[0001] The invention relates to the technical field of special containers, and in particular to a multi-door and window heat-insulating special container suitable for use in cold environments. Background Art

[0002] Integrated systems such as water tanks and electronic equipment are generally placed in an insulation chamber for use, especially in cold environments. The insulation chamber is used to place electronic equipment and water tanks. First of all, the insulation chamber has a large space area and is suitable for placing more large water tanks and integrated electronic equipment. Secondly, a heating device can be installed in the insulation chamber to prevent the water in the water tank or the water pipes connecting the water tank from freezing. In addition, the door and wall materials used in the insulation chamber are more abundant and have good cold resistance. However, when exploiting shale oil fields, electronic equipment and water tanks are needed to ensure the safety and efficiency of oil field exploitation. The exploitation area of ​​the oil field is large, and both water tanks and electronic equipment need to be synchronized with the shale oil exploitation location, that is, the distance between the exploitation location and the insulation chamber cannot be too far apart. Therefore, the insulation chamber is a fixed structure. When changing the exploitation location, the insulation chamber needs to be dismantled or rebuilt near the exploitation location to exploit the oil field, which has low exploitation efficiency and increased exploitation costs.

[0003] When shale oil fields are mined in cold regions, equipment in integrated systems, such as water tanks and electronic equipment, are usually placed in an insulation chamber. This design not only ensures that the circulating water in the water tank cannot freeze, but also allows the water in the water tank to be preheated or maintained at a temperature by absorbing the heat generated by the electronic equipment when it is working, thereby reducing the need for additional heating and improving the energy efficiency of the overall system. The reason why integrated systems such as water tanks and electronic equipment are placed in an insulation chamber is that the insulation chamber provides enough space to accommodate large water tanks and other necessary equipment. Secondly, additional heating facilities can be installed in the insulation chamber to prevent the water in the water tank and the connecting water pipes from freezing due to low temperatures. In addition, the building materials used in the insulation chamber are not only of a wide variety, but also have good thermal insulation properties and can effectively withstand severe cold climates. However, in actual operations, in order to ensure the safety and efficiency of shale oil mining, electronic equipment and water tanks need to be synchronized with the mining location. This means that the insulation chamber must be located close to the mining site. Since the insulation chamber is a fixed structure, when the mining site is changed, it needs to be dismantled and rebuilt near the new mining location, which not only reduces mining efficiency but also increases costs. Summary of the invention

[0004] In order to ensure that the insulated box with multiple doors and windows has good thermal insulation performance, this basic solution provides a special insulated container with multiple doors and windows suitable for cold environments.

[0005] A multi-door and window insulated special container suitable for cold environments comprises a main box body, a water tank and equipment for use. The water tank is fixedly installed in the main box body, one end of the water tank is pressed against one side wall of the main box body, and the other end is pressed against the other side wall of the main box body; a maintenance area is arranged in the main box body, and the maintenance area is close to the water tank; an installation area is also arranged in the main box body, and the installation area is close to the maintenance area and far away from the water tank; equipment for use is arranged in the installation area; the size of the main box body is the standard size of the container; the main box body is made of multi-layer insulation wall panels, a rigid main frame and insulation doors ; The insulation door is made of multi-layer insulation board, and the insulation door includes the first insulation door, the second insulation door and the third insulation door; the load-bearing weight of the rigid main frame is not higher than 5000Kg; the opening direction of the first insulation door is toward the water tank, the opening direction of the second insulation door is toward the maintenance area, and the opening direction of the third insulation door is toward the installation area. The third insulation door is used to install and use equipment in the main box; the main box is used in the external environment of the main box within -20℃. When the equipment in the main box is powered off, the water tank will not freeze within 8 hours.

[0006] Beneficial effects: Compared with the existing technology, the existing technicians did not consider using containers for loading, because the load capacity, plane area and thermal insulation performance of containers are relatively poor compared with fixed insulation chambers. If the design of the standard size of the container is adopted, the water tank and the equipment used will almost occupy the plane area of ​​the container, and ordinary containers are single-door designs. If a single-door container is used, there cannot be an aisle area in the container. Without an aisle area, it is difficult for the staff to enter the container to install the equipment and water tank, and to inspect and repair the equipment and water tank. In addition, since the water tank and the equipment are heavy, when the skeleton structure of the ordinary container is used for loading, it is easy for the container to be overloaded and cause the container to crack.

[0007] This basic solution is different. First, this basic solution adopts a multi-door and window design, with the first, second and third insulation doors set on the main box body; the first insulation door opens toward the water tank, the second insulation door opens toward the maintenance area, and the third insulation door opens toward the equipment; compared with the single door and window design, there is no need to use a large area such as an aisle, which is equivalent to saving the limited space in the container to place the water tank and equipment; however, the prior art believes that when a multi-door and window design is adopted, the more doors there are, the lower the insulation effect in the container. This basic solution uses multi-layer insulation doors on the insulation door to improve the insulation performance of the insulation box and prevent the phenomenon that the more doors there are, the lower the insulation effect in the container.

[0008] Secondly, the water tank and the equipment occupy a large area. One end of the water tank is pressed against one side wall of the main box body, and the other end is pressed against the other side wall of the main box body. An installation area is set in the main box body, and the installation area is filled with equipment. A maintenance area is set between the water tank and the installation area, which can not only meet the installation and maintenance of the equipment, but also further utilize the limited space in the container, ensuring that the equipment and the water tank can be fixedly installed in the main box body.

[0009] Moreover, unlike ordinary containers, this embodiment adopts a rigid main frame, which has a good weight bearing capacity of no more than 5000Kg, and can meet the loading capacity of water tanks and equipment used;

[0010] At the same time, without installing a heating device and not using the heating device when the power is off, the main box is used in an external cold environment of less than -20°C. When the equipment in the main box is powered off, the water tank will not freeze within 8 hours and its thermal insulation performance is excellent.

[0011] Finally, the intelligent special container of this basic solution is adopted, and the size of the main box body of the special container is the standard size of the container, that is, it is mobile and highly flexible.

[0012] Preferably, the rigid main frame includes a bottom frame, a rectangular top frame, columns, multiple hanging ears and side frames; a rectangular structured space is formed between the bottom frame, the rectangular top frame, the columns and the side frames; the top end of the column is fixedly connected to the rectangular top frame, the bottom end is fixedly connected to the bottom frame, and the side frame is installed in the middle of the column; the hanging ears are fixedly installed on the bottom frame and the rectangular top frame respectively.

[0013] Beneficial effects: Compared with the frame of ordinary containers, the rigid main frame strengthens the stability and firmness of the overall structure of the whole special container by fixedly connecting the bottom frame, rectangular top frame, columns and side frames; secondly, the lifting ears are fixedly installed on the bottom frame and the rectangular top frame, so that the main box body can be lifted vertically by a crane and can also be moved horizontally, which improves the flexibility of the special container.

[0014] Preferably, the bottom frame includes multiple secondary beams, multiple supporting beams and multiple first main beams; the first main beams are fixedly connected in sequence to form a rectangular frame, the secondary beams are fixedly installed on the first main beams, the supporting beams are perpendicular to the secondary beams, and the head and tail ends of the supporting beams are fixedly installed on the first main beams; wherein the secondary beams include multiple first beams and multiple second beams; the two ends of the first beam are respectively fixedly connected to the first main beam and the supporting beam, and the first beam is used to support the water tank; the second beam passes through the supporting beam and is fixedly connected to the first main beam, and the second beam is used to support the equipment; the area between the first beam and the second beam is a maintenance area.

[0015] Beneficial effect: the bottom frame equivalent to the existing ordinary container is generally a rectangular structure, and then a bottom plate is installed on it; while this bottom frame combines the secondary beam, the supporting beam and the first main beam. The first beam is used to support the water tank, and the second beam is used to support the equipment. There is no other secondary beam between the first beam and the second beam. At this time, because this is the maintenance area, the load-bearing capacity of the area is small. Therefore, when the supporting strength for supporting the equipment and the water tank is reached, the secondary beam is not installed in the maintenance area, so as to reduce the weight of the entire box.

[0016] Preferably, a reinforcing rib is provided at the connection between the bottom frame and the column, one side of the reinforcing rib is fixedly connected to the column, and the other side of the reinforcing rib is fixedly connected to the bottom frame.

[0017] Beneficial effect: Since the two sides of the maintenance area are the water tank and the installation area, the load on these two sides is relatively large. In order to ensure that there is enough space to install the water tank and the equipment, and to further increase the load-bearing capacity of the main box, the reinforcing ribs are fixed and installed between the columns and the bottom frame, which not only saves space in the main box, but also fixes the bearing capacity of the columns and the bottom frame. At the same time, the cracking phenomenon is prone to occur first between the columns and the bottom frame. Through the design of the reinforcing ribs, the stability of the connection structure at this location is improved.

[0018] Preferably, the wall panel includes an outer skin, a first insulation board and an inner skin; the outer skin is fixedly connected to the outer surface of the rigid main frame, the inner surface of the rigid main frame is fixedly connected to the outer surface of the first insulation board, and the inner surface of the first insulation board is fixedly connected to the outer surface of the inner skin; wherein the first insulation board is a cotton rock board.

[0019] Beneficial effects: The thermal insulation effect is achieved by arranging multiple layers of wall panels such as an outer skin, a first insulation board and an inner skin; and the outer skin is arranged on the outer side of the rigid main frame, and the first insulation board is arranged on the inner side, which has a good thermal insulation effect, and the first insulation board is a cotton rock board, which has a good thermal insulation effect and a low cost; at the same time, the first insulation board is located between the inner skin and the rigid main frame and can also play a flame retardant role. Since most of the equipment used in the main box is electrical equipment, in order to prevent the electrical equipment from malfunctioning and burning, so as to burn the special container in a short time, the first insulation board is arranged between the inner skin and the rigid main frame, which can also play a flame retardant role.

[0020] Preferably, a thermal break bridge is provided on the first insulation board, and the inner skin is disconnected from the rigid main frame by the thermal break bridge, so as to block the heat exchange between the rigid main frame and the wall panel.

[0021] Beneficial effect: By setting a thermal break bridge, and setting the thermal break bridge between the main frame and the inner skin, rather than between the rigid main frame and the outer skin, this is because the equipment used in the box will generate heat by itself when in use. In order to achieve heat circulation in the box, a thermal break bridge is set between the rigid main frame and the inner skin, and the heat inside the container can be used for insulation. The existing technology sets a thermal break bridge between the rigid main frame and the outer skin. Although this can reduce the heat exchange between the external environment and the inside of the main box, this special container is mainly used in cold environments. If a thermal break bridge is set between the rigid main frame and the outer skin, ice is likely to form at the thermal break bridge, thereby reducing the thermal insulation performance of the main box.

[0022] Preferably, the thermal break bridge includes a first thermal break bridge and a second thermal break bridge; the wall panel consists of a bottom panel, a side panel and a top panel; the bottom end of the side panel is fixedly connected to the bottom panel, and the top end of the side panel is fixedly connected to the top panel; a rectangular structure is formed between the bottom panel, the side panel and the top panel; the first thermal break bridge and the second thermal break bridge are both arranged on the side panel, the first thermal break bridge is close to the top panel, and the second thermal break bridge is close to the bottom panel.

[0023] Beneficial effect: Heat-breaking bridges are arranged near the bottom plate and the top plate, which can prevent heat exchange between the external environment and the inside of the main box from happening in all directions, further improving the thermal insulation inside the main box.

[0024] Preferably, the thermal insulation door comprises an outer skin, a wood panel, a second thermal insulation board, a door panel frame and an inner skin; the outer skin, the wood panel, the second thermal insulation board, the door panel frame and the inner skin are fixedly connected in sequence; wherein the second thermal insulation board is an extruded board with a thickness of 55-75 mm.

[0025] Beneficial effects: The difference between the thermal insulation door and the wall panel and the rigid main frame is that the thermal insulation door uses wood board and the second thermal insulation board is located between the outer skin and the door panel frame, while the wall panel has the first thermal insulation board located between the rigid main frame and the inner skin; this is because the thermal insulation door is more for heat preservation and heat insulation, so the second thermal insulation board is located between the outer skin and the door panel frame. The second thermal insulation board is an extruded board, which not only has a good thermal insulation effect but also has a low cost; the thickness of the second thermal insulation board is 55-75mm, which not only has a good thermal insulation effect, but also avoids the second thermal insulation board from being too thick to reduce the thickness of the wood board, so that the thermal insulation door can also achieve anti-collision, that is, a strong anti-collision effect.

[0026] Preferably, a third thermal break bridge is provided on the thermal insulation door, and the third thermal break bridge is arranged on the outer surface of the second thermal insulation layer and is flush with the outer skin.

[0027] Beneficial effect: The third thermal break bridge is arranged on the outer surface of the second insulation layer and is flush with the outer skin. Relative to the setting positions of the first thermal break bridge and the second thermal break bridge, since the insulation door includes the outer skin, the wood board, and the second insulation board in sequence, the wood board will block a certain amount of heat, and setting the third thermal break bridge here can also make the setting more convenient.

[0041] Embodiment 1

[0042] The present embodiment provides a multi-door and window insulated special container suitable for use in cold environments. In the present embodiment, the length of the special container is 5994-6000 mm, the width is 2395-2400 mm, and the height is 2598-2603 mm, which complies with the relevant ISO standards and meets the size of a 20-inch standard container.

[0043] like Figure 1 As shown, a multi-door and window insulated special container suitable for use in cold environments includes a main box body, which is made of multi-layer wall panels 5, a rigid main frame 6 and an insulated door 7. A water tank is fixedly installed in the main box body. A water tank is fixedly installed in the main box body, one end of the water tank is pressed against the front wall of the main box body, and the other end is pressed against the rear wall of the main box body. The insulated door 7 includes a first insulated door 7, a second insulated door 7 and a third insulated door 7; the load-bearing weight of the rigid main frame 6 is not higher than 5000Kg; the opening direction of the first insulated door 7 is toward the water tank, the opening direction of the second insulated door 7 is toward the maintenance area, and the direction of the third insulated door 7 is toward the installation area, and the third insulated door 7 is used to install and use equipment in the main box body.

[0044] The rigid main frame 6 includes a bottom frame 1, a rectangular top frame 3, columns, hanging ears and side frames 2. Specifically, Figure 2As shown, the bottom frame 1 includes 14 secondary beams 13, 2 support beams 14 and 4 first main beams 12. The 4 first main beams 12 are fixedly connected in sequence to form a rectangular frame, and the secondary beams 13 are fixedly installed on the first main beams 12, and the secondary beams 13 are evenly distributed inside the rectangular frame. The support beam 14 is perpendicular to the secondary beam 13, and both ends of the support beam 14 are fixedly installed on the first main beam 12, located in the middle of the frame. Among them, it is located on the left side of the frame, and 4 secondary beams 13 pass through the support beam 14, which is located on the right side of the frame. Five secondary beams 13 are fixedly installed between each support beam 14 and the first main beam 12. Among them, the secondary beam 13 includes multiple first beams 13 and multiple second beams 13; the two ends of the first beam 13 are respectively fixedly connected to the first main beam 12 and the support beam 14, and the first beam 13 is used to support the water tank; the second beam 13 passes through the support beam 14 and is fixedly connected to the first main beam 12, and the second beam 13 is used to support the equipment; the area between the first beam 13 and the second beam 13 is a maintenance area.

[0045] Specifically, no equipment is placed in the maintenance area. The maintenance area is for maintenance personnel to enter through the second insulation door 7, and can perform corresponding inspection and maintenance on the equipment used in the installation area. The first insulation door 7 and the third insulation door 7 are normally closed. The second insulation door 7 is used more frequently, and the size of the second insulation door 7 is just enough to accommodate an adult. Compared with the door of an ordinary container, the second insulation door 7 is smaller, so when it is opened for maintenance, the external temperature will not freeze the water tank in a short time. The first insulation door 7 is used to operate the water tank, such as adding water to the water tank.

[0046] The bottom frame 1 is used to support various equipment and water tanks, and in the special container designed with multiple doors and windows, a certain distance is left between the secondary beams 13 to ensure that the maintenance personnel can have a place to stand for maintenance. Compared with the single-door container, there is no need to leave an aisle, thereby greatly expanding the usable area and volume in the container. In this embodiment, the design of the bottom frame 1 must not only bear the weight of the entire upper equipment, but also be as small as possible to reduce the internal space occupied by the container. Therefore, in this embodiment, the main beam of the bottom frame 1 is a rectangular tube of 200*100*4mm, the secondary beam 13 is a cap beam of 80*80*60*4mm, and the middle support beam 14 is a rectangular tube of 100*60*4mm.

[0047] In this embodiment, the container has 4 columns, which are respectively located at the four ends of the rectangular frame formed by the four first main beams 12. The rectangular top frame 3 is flush with the rectangular frame formed by the four first main beams 12 and is located directly above the first main beams 12. The bottom end of the column is fixedly connected to the main beam, and the top end is fixedly connected to the rectangular top frame 3. The rectangular top frame 3, the columns, and the four main beams form a rectangular parallelepiped structure. Figure 3As shown, a reinforcing beam 32 is also fixedly installed in the middle of the rectangular top frame 3. In order to ensure that the rectangular top frame 3 and the reinforcing beam 32 can play a role in stabilizing the structure, while reducing its size to obtain more equipment placement space. In this embodiment, the rectangular top frame 3 is composed of 100*60*4mm rectangular tubes, and the reinforcing beam 32 is a 100*60*4 rectangular tube.

[0048] The lifting lugs include lower lifting lugs 11 and upper lifting lugs. There are 2 groups of lower lifting lugs 11, each with 2 pieces, which are fixedly mounted on the side walls of the main beams at the left and right ends. There are 3 groups of upper lifting lugs, each with 2 pieces, which are fixedly mounted on the left, middle and right ends of the rectangular top frame 3. Since it is necessary to place equipment in the rigid main frame 6, in order to save costs and meet the lifting strength, it is calculated that the weight of all equipment in the rigid main frame 6 is ≤5000kg; the lifting lugs are A05 type lifting lugs in accordance with GB / T 35981-2018 "Technical Specifications for Welding Lifting Lugs for Metallurgical Equipment", and the nominal lifting weight of the lifting lugs is 5t. In addition, 6 upper lifting lugs are set at the top to facilitate lifting, and 4 lower lifting lugs 11 are set at the bottom and are located at the left and right ends, respectively, which can facilitate the subsequent dragging of the special container body during transportation. Such a setting can not only save costs while meeting the lifting strength, but also facilitate lifting, and make the special container mobile and highly flexible.

[0049] The side frame 2 is a door frame 21, and the side frame 2 includes a first square tube and a second square tube. The difference between the first square tube and the second square tube is that the first square tube is a rectangular tube with holes, and the second square tube is a rectangular tube without holes. The first square tube includes a first vertical square tube and a first horizontal square tube. The top of the first vertical square tube is fixedly connected to the rectangular top frame 3, and the bottom end is fixedly connected to the main beam. The left end of the first horizontal square tube is fixedly connected to the column, and the right end is fixedly connected to the first vertical square tube. The first vertical square tube and the adjacent first horizontal square tube are in a "T" shape. There are two second square tubes, and their sides are fixedly installed on the main beam, the left end is fixedly connected to the first vertical square tube, and the right end is fixedly connected to the column.

[0050] like Figure 4 As shown, a bending reinforcement rib 4 is fixedly installed between the column and the main beam, and there are 8 bending reinforcement ribs 4. The upper arm of the bending reinforcement rib 4 is fixedly connected to the column, and the lower arm of the bending reinforcement rib 4 is fixedly connected to the top beam. This is because the stress at the connection position between the main beam and the column is relatively concentrated, and by fixing the bending reinforcement rib 4, the structural strength of the entire rigid main frame 6 is increased.

[0051] like Figure 5 and Figure 6As shown, in order to further improve the thermal insulation effect of the box, a wall panel 5 is installed outside the box of the special container. The wall panel 5 is used to insulate the outer layer of the box. The wall panel 5 includes an outer skin 51, a first thermal insulation board 54 and an inner skin. The outer skin 51 is located outside the rigid main frame 6, the first thermal insulation board 54 is located inside the rigid main frame 6, and the inner skin is located inside the box and close to the first thermal insulation board 54, that is, the box of the special container includes an outer skin 51, a rigid main frame 6, a first thermal insulation board 54 and an inner skin from outside to inside. The outer skin 51 is fixedly connected to the outer surface of the rigid main frame 6, the inner surface of the rigid main frame 6 is fixedly connected to the outer surface of the first thermal insulation board 54, and the inner surface of the first thermal insulation board 54 is fixedly connected to the outer surface of the inner skin. The first thermal insulation board 54 is a rock wool board. Compared with a high-density polyurethane foam board, the cost of a rock wool board is one-tenth of the cost of a high-density polyurethane foam board, and the rock wool board can also achieve a good thermal insulation effect. The thickness of the rock wool board is 75 mm, which not only improves the structural stability of the entire wall panel 5 while achieving a good thermal insulation effect, but also reduces the occupation of the volume space of the special container. In this embodiment, the thickness of the outer skin 51 and the inner skin are both 1.5 mm, which can improve the overall structural stability of the entire special container while meeting the requirements of protecting the thermal insulation layer and withstanding certain external impacts.

[0052] like Figure 7 and Figure 8 As shown, a thermal break bridge 52 is provided on the first insulation board 54, and the inner skin is disconnected from the rigid main frame 6 by the thermal break bridge 52. Specifically, the thermal break bridge 52 includes a first thermal break bridge 52 and a second thermal break bridge 52. The wall panels 5 of the special container body can be divided into a top panel 56, a side panel 55 and a bottom panel 57 according to their positions. The first thermal break bridge 52 is located on the side panel 55 and is close to the top panel 56; the second thermal break bridge 52 is located on the side panel 55 and is close to the bottom panel 57. Through this combined thermal insulation treatment, the special container can be prevented from exchanging heat with the outside world in all directions, and the structural changes ensure that the interior of the special container has good thermal insulation.

[0053] The insulation door 7 includes an outer skin 51, a wood board, a second insulation board, a door panel frame and an inner skin in sequence from the outside to the inside of the special container. The outer skin 51, the wood board, the second insulation board, the door panel frame and the inner skin are fixedly connected in sequence, which can be connected by glue or welding. The second insulation board is an extruded board with a thickness of 55-75mm. The insulation door 7 is provided with a third thermal break bridge 52, which is fixedly installed on the outer surface of the second insulation layer and is flush with the outer skin 51. The water tank is fixedly installed on the bottom plate 57 and is located inside the special container. The water tank is a stainless steel water tank with a length, width and height of 500mm, 2000mm and 2160mm respectively.

[0054] The beneficial effects of this embodiment

[0055] Compared with the existing technology, traditional insulation rooms usually adopt a fixed design, and do not consider the use of containers for loading. The main reason is that the load capacity, plane area and thermal insulation performance of ordinary containers are relatively insufficient. Specifically, if a standard-sized container is used, the water tank and the equipment used will almost occupy the entire plane area, while ordinary containers are mostly single-door designs, which will result in insufficient aisle space inside for staff to enter for installation and maintenance. In addition, due to the heavy weight of the water tank and the equipment used, the skeleton structure of the ordinary container may not be able to withstand such a large load, which can easily cause the container to crack.

[0056] This embodiment solves the above-mentioned problems and has the following characteristics: First, a multi-door and window design is used, in which a first insulation door, a second insulation door, and a third insulation door are set on the main box body. The first insulation door opens toward the water tank, which is convenient for filling and checking the water tank; the second insulation door opens toward the maintenance area, which is convenient for staff to perform equipment maintenance; the third insulation door opens toward the equipment in use, which is convenient for operation and monitoring. This multi-door and window design avoids the problem of setting up aisles that take up a lot of space, thereby saving the limited area in the container and allowing the water tank and equipment to be arranged more efficiently. Although the multi-door and window design may slightly reduce the insulation effect, the insulation performance is further improved by using multi-layer boards to make insulation doors.

[0057] Secondly, optimize the spatial layout: one end of the water tank is close to one side wall of the main box, and the other end is close to the other side wall to ensure that the water tank is firmly installed. A special installation area is set up in the main box, which is full of equipment. A maintenance area is set up between the water tank and the installation area, which not only meets the installation and maintenance needs of the equipment, but also makes full use of the limited space, ensuring that the equipment and water tank can be firmly fixed in the main box.

[0058] Moreover, the enhanced skeleton structure is different from ordinary containers. This embodiment adopts a rigid main skeleton, which has a stronger load-bearing capacity and a maximum load-bearing weight of up to 5,000 kg, which can meet the loading requirements of water tanks and equipment. The first beam is used to support the water tank, and the second beam is used to support the equipment. There is no other secondary beam between the first beam and the second beam. At this time, because this is a maintenance area, the load-bearing area is small. Therefore, when the support strength for supporting equipment and water tanks is reached, no secondary beam is installed in the maintenance area, so as to reduce the weight of the entire box. The reinforcing ribs are fixedly installed between the columns and the bottom frame, which not only saves space in the main box, but also fixes the bearing capacity of the columns and the bottom frame. At the same time, the cracking phenomenon is prone to occur first between the columns and the bottom frame. The design of the reinforcing ribs improves the stability of the connection structure there.

[0059] At the same time, the excellent thermal insulation performance is achieved by disconnecting the inner skin from the rigid main frame through a thermal bridge to block the heat exchange between the rigid main frame and the wallboard, and disconnecting the outer skin on the thermal insulation door from the door frame through a thermal bridge to block the heat exchange between the inside of the main box and the outside environment of the main box. Even without the installation of additional heating devices, the main box can be used normally in an environment within -20℃. In the event of a power outage, when the equipment in the main box stops working, the water tank will not freeze within 8 hours, demonstrating excellent thermal insulation performance.

[0060] Next, the first insulation board is a cotton rock board, and the second insulation board is an extruded board. Compared with the prior art that uses polyurethane foam board as the insulation board, its cost is lower, about one tenth of the price of polyurethane foam board, and can also meet the insulation effect of special containers.

[0061] Finally, high mobility and flexibility: The special container of this embodiment adopts the standard container size, has high mobility and flexibility, and is suitable for various working environments. At the same time, the lifting lugs are fixed on the bottom frame and the rectangular top frame, so that the main box body can be lifted vertically by a crane and can also be moved horizontally, which improves the flexibility of the special container. In summary, this basic solution effectively solves the shortcomings of traditional containers in terms of load capacity, space utilization and insulation through multi-door and window design, optimized space layout, enhanced frame structure and excellent insulation performance, and provides a more efficient, flexible and reliable special container.

[0062] Embodiment 2

[0063] like Fig. 9 As shown, unlike the previous embodiment, in this embodiment, a sealing strip is provided between the second thermal insulation door 8 and the wall. The sealing strip is attached to the second thermal insulation door 8. Specifically, the sealing strip is located on the door panel frame. Whether the door is opened or closed, the sealing strip will be touched and pressed. The sealing strip is provided with three claw grooves, each with a length of 1 cm. 3 The distance between two adjacent claw grooves is 2.8 cm. The claw groove at the bottom is 140 cm away from the bottom plate 57. A storage device is fixedly installed on the inner wall of the wall panel 5, and a spare sealing strip 108 is placed in the storage device. The sealing strip is a rubber strip.

[0064] When the sealing strip is oxidized and discolored, the sealing strip is torn open through the claw groove, and the spare sealing strip 108 falls down, so that the worker can quickly and conveniently replace the sealing strip.

[0065] Specifically, the storage device is located between the second heat preservation door 8 and the third heat preservation door 9. The storage device is fixedly mounted on the inner wall of the main box body. The storage device includes a spring 105 transmitter, a spring 105, a slide plate 106, and a support plate 107.

[0066] One end of the spring 105 is installed on one side of the spring 105 launcher, and the other end of the spring 105 is pressed against the slider. A spare sealing strip 108 is placed on the slider 106. The support plate 107 is used to support the slider 106, and the slider 106 is slidably connected to the support plate 107. Three locking holes are opened on the support plate 107, and the structure of the locking holes is consistent with the structure of the claw groove. The spring 105 launcher is also installed on the support plate 107, and the spring 105 launcher is used to pop out the spring 105 or lock the spring 105.

[0067] The locking device is fixedly mounted on the inner wall of the main box body and is located above the support plate 107. The locking device includes a first motor 101 and a locking rod 102. The first motor 101 is connected to the locking rod 102, and the movement direction of the locking rod 102 is toward the locking hole. Three claw needles 103 are fixedly connected to the bottom of the locking rod 102; the three claw needles 103 correspond to the three locking holes respectively. The first pressure sensor is fixedly mounted on the inner wall of the main box body, the first pressure sensor is close to the sealing strip, and is used to obtain the number of times the sealing strip is pressed. The installation position of the first sensor will not affect the opening and closing of the second thermal insulation door 8. When the number of times the sealing strip is pressed reaches a certain value, it is considered that the sealing strip has been damaged after being pressed by the second thermal insulation door 8, and the pressing sealing strip should be replaced. This value can be a conventional design, and the specific value is subject to the setting of the worker. The structure of the claw needle 103 is consistent with the structure of the claw groove. A placement hole is opened on the slide plate 106, and the second pressure sensor can be stored in the placement hole. The second pressure sensor and the surface of the slide plate 106 are flush. The second pressure sensor is used to obtain the pressure value on the slide plate 106 to determine whether the spare sealing strip 108 is placed on the slide plate 106. The first pressure sensor and the second pressure sensor are wirelessly connected to the first motor 101 respectively; the first motor 101 is wirelessly connected to the spring 105 transmitter.

[0068] How to use this embodiment

[0069] like Fig.10 As shown, Fig.10It is a schematic diagram of the spring 105 popping out the slide plate 106; when the first pressure sensor obtains that the sealing strip is compressed for a certain number of times, it sends a signal to the first motor 101, the first motor 101 is driven, and the locking rod 102 moves upward and moves out of the locking hole; then the first motor 101 sends a signal to the spring 105 transmitter, the spring 105 transmitter pops out the spring 105, and pushes the slide plate 106, and the slide plate 106 is just located in the opening direction of the second insulation door 8, which is convenient for the worker to see. After the worker takes out the spare sealing strip 108, the worker restores the slide plate 106, that is, the slide plate 106 is pressed against the spring 105, and the spring 105 transmitter senses that the spring 105 is pressed, and the spring 105 is locked. When the second pressure sensor senses that there is no pressure on the slide plate 106, the first motor 101 does not drive the locking rod 102 to move downward. When the worker places other spare sealing strips 108 on the slide plate 106, the second pressure sensor sends a signal to the first motor 101, and the first motor 101 drives the locking rod 102 to move downward, and the claw needle 103 pierces the spare sealing strip 108. A claw groove is left on the sealing strip, and the claw needle 103 of the locking rod 102 is inserted into the locking hole to prevent the spare sealing strip 108 from moving at will due to the movement of the container, thereby fixing the spare sealing strip 108.

[0070] The beneficial effects of this embodiment

[0071] Since the second heat-insulating door 8 is opened and closed many times, the sealing strip is easily damaged. Once the sealing strip is damaged, the heat-insulating performance of the heat-insulating door 7 is reduced.

[0072] By arranging the first motor 101, the sliding rod, the storage device and the spare sealing strip 108 on the inner wall of the main box body, firstly, the plane area of ​​the main box body will not be occupied. The sealing strip is provided with a claw groove, which can facilitate the worker to tear off the damaged sealing strip.

[0073] Secondly, the first pressure sensor is used to record the number of times the sealing strip is pressed by the second insulation door 8. Once the number of times the sealing strip is damaged is reached, the first pressure sensor sends a signal to the first motor 101. At this time, the first motor 101 lifts the locking rod 102, and then the first motor 101 sends a pop-up signal to the spring 105 transmitter. The spring 105 transmitter pops up the spring 105 and pushes the slide bar. The slide bar slides on the support plate 107, and Fig.10 As shown, when the second thermal insulation door 8 is just slid to the opening direction, the staff can know in time that the sealing strip is damaged, and can quickly take the spare sealing strip 108 on the slide plate 106 to replace the original sealing strip. By allowing the staff to find out in time that the sealing strip is damaged and reminding the staff to replace the sealing strip in time, the thermal insulation effect of the second thermal insulation door 8 can be guaranteed, and the phenomenon of the thermal insulation performance of the main box body decreasing due to the number of times the second thermal insulation door 8 is opened and closed for a long time can be prevented.

[0074] Then, the worker pushes the slide plate 106 toward the spring 105 and presses against the spring 105, so that the spring 105 returns to the compressed position. The spring 105 transmitter locks the spring 105, that is, the worker can easily restore the slide plate 106. The worker puts the new spare sealing strip 108 on the restored slide plate 106 again. At this time, the second pressure sensor senses that there is an object pressing on the slide plate 106, and sends a signal to the first motor 101. The first motor 101 drives the locking rod 102, and the claw needle 103 inserts the sealing strip out of the claw groove and inserts it into the locking hole. In this way, not only does the worker not need to poke a claw groove on the sealing strip, but also improves the worker's work efficiency and reduces the worker's burden; and the claw needle 103 is inserted into the locking hole to fix the spare sealing strip 108, which has a fixing effect. Prevent the spare sealing strip 108 from falling out of the slide plate 106 during the handling and movement of the special container or when the worker accidentally touches it.
