Description

Technical Field

[0001] This application relates to the field of container house technology, and in particular to a container house with a radiation cooling film and a cooling film coating process. Background Technology

[0002] Container houses are a type of movable and reusable building product. They are also known as "modular container houses" or "container houses." They adopt modular design and factory production, using containers as basic units. They can be used individually or combined horizontally and vertically to create spacious living spaces, and can be stacked vertically.

[0003] Conventional container houses have a fixed frame structure. When it is necessary to temporarily increase the internal space of a container house, an additional container house needs to be set up and the two container houses are assembled together. However, such temporary additions often require specific space size requirements. Directly using two container houses requires transportation and hoisting, which is a cumbersome process. In addition, the land area occupied by two container houses is doubled, resulting in a waste of space resources. Summary of the Invention

[0004] To address the issues of cumbersome processes and wasted space resources when conventional container houses require temporary expansion, this application provides a container house with a radiant cooling film.

[0005] The container house with a radiative cooling film provided in this application adopts the following technical solution:

[0006] A container house with a radiative cooling film includes a base plate, side plates are perpendicularly provided on both sides of the base plate along its length, and door panels are perpendicularly provided at both ends of the base plate along its length.

One of the blades is provided with two pin sleeves that are distributed opposite each other in the vertical direction, and the other blade is fixed with a pin shaft. The pin shaft is located between the two pin sleeves and is coaxially distributed with the pin sleeves. Both ends of the pin shaft are threaded with a limiting shaft. The diameter of the limiting shaft is the same as the inner diameter of the pin sleeve. Each pin sleeve sidewall is threaded with a limiting screw. The end of the limiting screw passes into the pin sleeve and abuts against the limiting shaft perpendicularly.

[0012] Optionally, a knob is coaxially fixed to the limiting screw.

[0013] Optionally, the bottom surface of the cover plate is provided with a soft protective cover for covering the perimeter of the outdoor areas at the corresponding two outdoor areas.

[0014] Optionally, the top plate and the bottom plate are provided with angle steel on opposite sides, and the two outer sides of the angle steel are covered with a first elastic sealing gasket. The side walls of the first plate and the second plate are embedded with a second elastic sealing gasket. When the first plate and the second plate are arranged along the length of the bottom plate, the second elastic sealing gaskets on the first plate and the second plate abut against each other.

[0015] Optionally, a first sealing groove is provided on both sides of the first plate, and a second sealing groove corresponding to the first sealing groove is provided on both second plates. A third sealing groove is provided at the bottom of the second sealing groove.

[0038] The following is in conjunction with the appendix Figure 1-9 The present invention will be further described in detail below with reference to specific preferred embodiments.

[0039] In the description of this invention, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this invention. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the scope of protection of this invention.

[0040] This application discloses a container house with a radiative cooling film. For example... Figure 1 The container includes a base plate 1, with side plates 4 perpendicularly mounted on both sides along its length, and door panels 2 perpendicularly mounted at both ends along its length. Each door panel 2 is equipped with a safety door for personnel access. The door panels 2 and side plates 4 together form a usable area, and a top plate 3 is mounted on the door panels 2 and side plates 4. Both the top plate 3 and side plates 4 are coated with a radiative cooling film. The radiative cooling film can reflect sunlight and transfer heat to outer space via infrared radiation in the atmospheric window band, thereby reducing the indoor temperature of the container.

[0041] like Figure 1 and Figure 2 The side panel 4 includes two support plates 43, a first plate 41, and two second plates 42. The two support plates 43 correspond to the two door panels 2 respectively, and the top and bottom ends of each support plate 43 are fixed to the top plate 3 and the bottom plate 1 respectively. The two second plates 42 are distributed on both sides of the first plate 41 and are connected to each other by hinges. The top and bottom ends of the two second plates 42 are provided with sliding shafts 44 on the side away from the first plate 41. The top plate 3 and the bottom plate 1 are provided with sliding grooves 441 for the sliding shafts 44 to be inserted and moved.

[0042] like Figure 3 Each of the two second panels 42 has a recessed groove 45 on the side away from the first panel 41. The recessed groove 45 extends along the height direction of the second panel 42. A roller 46 is rotatably connected inside the recessed groove 45. A curtain 461 is wound on the roller 46. A pull rod 47 is connected to the head of the curtain 461. A pull groove 48 for the pull rod 47 to be inserted is opened on the side of the support plate 43 away from the door panel 2. A fixing component for fixing the pull rod 47 is provided on the support plate 43. When the first panel 41 is located outside the use area and forms an angle with the two second panels 42, the first panel 41 and the two second panels 42 enclose the outdoor area.

[0043] The fixing component includes a locking screw 49, which is threaded onto the inner wall of the support plate 43, and the end of the locking screw 49 passes into the pull groove 48 and abuts against the pull rod 47.

[0044] In the initial state, the support plate 43, the first plate 41, and the second plate 42 are arranged along the length of the base plate 1 to form the side plate 4. When the external area of ​​the enclosure needs to be constructed, the operator pushes the first plate 41 and the second plate 42 outward, so that the first plate 41 and the two second plates 42 form a U-shape. During the movement, the second plate 42 drives the sliding shaft 44 to move along the slide groove 441, and at the same time, the curtain 461 is pulled open to cover the area between the support plate 43 and the second plate 42. The material of the curtain 461 can be selected according to the usage environment and purpose of the enclosure, such as waterproof, ventilated, or sunshade.

[0045] like Figure 4 The top plate 3 has an adjustment groove 201 extending along its length. An adjustment seat 202 is slidably connected within the adjustment groove 201. A spindle 203 is vertically mounted on the adjustment seat 202, and a cover plate 5 is vertically inserted through the spindle 203. When the cover plate 5 is rotated to a position perpendicular to the top plate 3, it covers the area above the two outdoor areas. The operator can first adjust the position of the cover plate 5 by moving it, and then rotate the cover plate 5 to cover the two outdoor areas, thus providing both shielding and safety protection.

[0046] like Figure 1 and Figure 5 Two telescopic cylinders 204 are hinged to both ends of the cover plate 5 along its length. An anchor rod 205 is slidably connected inside each telescopic cylinder 204. A stud 206 is vertically provided on the side wall of the anchor rod 205. The stud 206 extends out of the telescopic cylinder 204, and a locking block 207 is threaded to one end of the stud 206. A waist-shaped groove 208 is provided on the telescopic cylinder 204 for the stud 206 to move. The operator can use tools such as a hammer to apply a downward force to the stud 206, causing the anchor rod 205 to insert downward into the soil. This restricts the rotation of the cover plate 5 and also shares the lateral load on the box-type house.

[0047] like Figure 6 Multiple hinges are spaced apart along the height of the first plate 41. Each hinge includes two blades 6, which are fixed to the side of the first plate 41 and the second plate 42 facing the use area, respectively. One blade 6 has two pin sleeves 61 distributed vertically opposite each other, and the other blade 6 has a pin shaft 62 fixed on it. The pin shaft 62 is located between the two pin sleeves 61 and is coaxial with the pin sleeves 61. Both ends of the pin shaft 62 are threaded to limit shafts 621. The diameter of the limit shaft 621 is the same as the inner diameter of the pin sleeve 61. Each pin sleeve 61 has a limit screw 63 threaded to its side wall. The end of the limit screw 63 passes into the pin sleeve 61 and abuts against the limit shaft 621 perpendicularly. A knob 631 is coaxially fixed on the limit screw 63.

[0048] When the limit screw 63 is separated from the limit shaft 621, the two blades can rotate freely. When the limit screw 63 abuts against the limit shaft 621, the rotation of the two blades is restricted, so that the first plate body 41 and the second plate body 42 are kept relatively fixed.

[0049] As Figure 4 , on the bottom surface of the cover plate 5 at the positions corresponding to the two outdoor areas, there is a soft protective cover 8 for covering the periphery of the outdoor area, and the protective cover 8 is in a U-shaped form.

[0050] The protective cover 8 extends downward beyond the first plate body 41 and the second plate body 42 to block the peripheries of the first plate body 41 and the second plate body 42, reducing the entry of dust, rainwater, etc. into the outdoor area; during storage, the operator folds the protective cover 8 and then presses it between the cover plate 5 and the top plate 3.

[0051] As Figure 7 and Figure 8 , on the opposite sides of the top plate 3 and the bottom plate 1, there are angle steels 9 spaced relatively from the side plate 4. Both outer side surfaces of the angle steel 9 are covered with first elastic sealing gaskets 91, and the side plate 4 abuts against the first elastic sealing gaskets 91.

[0052] As Figure 6 , second elastic sealing gaskets 92 are embedded in the side walls of the first plate body 41 and the second plate body 42. When the first plate body 41 and the second plate body 42 are arranged along the length direction of the bottom plate 1, the second elastic sealing gaskets 92 on the first plate body 41 and the second plate body 42 abut against each other tightly.

[0053] The first elastic sealing gasket 91 increases the sealing performance between the angle steel 9 and the side plate 4, and at the same time blocks the gap between the curtain cloth 461 and the top plate 3. The second elastic sealing gasket 92 increases the sealing performance between the first plate body 41 and the second plate body 42.

[0054] As Figure 3 and Figure 6 , on both sides of the first plate body 41, there are first sealing grooves 101 penetrating up and down. On both of the two second plate bodies 42, there are second sealing grooves 102 corresponding to the first sealing grooves 101. At the bottom of the second sealing groove 102, there is a third sealing groove 103. A first sealing rod 104 is fixed in the first sealing groove 101. A second sealing rod 105 is slidably inserted in the second sealing groove 102. The second sealing rod 105 is connected to the bottom of the third sealing groove 103 through a spring 106, and a waterproof cloth 107 is connected between the second sealing rod 105 and the opposite first sealing rod 104.

[0055] When the outdoor area is opened, the waterproof cloth 107 is stretched, which causes the second sealing plate to pull the spring 106. The spring 106 is stretched and produces elastic deformation. The waterproof cloth 107 covers the corner between the first plate 41 and the second plate 42, further increasing the protective performance of the outdoor area. When the first plate 41 and the second plate 42 return to the side plate 4 state, the second sealing plate moves closer to the third sealing groove 103 under the elastic tension of the spring 106, causing the waterproof cloth 107 to gradually retract into the second sealing groove 102.

[0056] like Figure 8 and Figure 9 A positioning sleeve 71 is rotatably connected to the side wall of the angle steel 9. The rotation axis of the positioning sleeve 71 is horizontal and perpendicular to the length direction of the base plate 1. A positioning rod 72 passes through the positioning sleeve 71. The side wall of the second plate 42 is provided with a guide sleeve 73 for inserting the positioning rod 72. The guide sleeve 73 is higher than the angle steel 9. When the positioning rod 72 is inserted into the guide sleeve 73, the second plate 42 is perpendicular to the length direction of the base plate 1. When the outdoor area is unfolded, the operator rotates the positioning sleeve 71 upwards and then slides the positioning rod 72 into the guide sleeve 73. The position of the second plate 42 is further stabilized by the hinge.

[0057] The principle of a container house with a radiation cooling film: The operator can decide whether to unfold the outer area of ​​the house for temporary use according to actual needs. The outer area has the advantages of easy unfolding and good protection performance. Moreover, the side panel 4 serves as the common foundation for the use area and the outer area, resulting in high resource utilization.

[0058] This application also provides a cooling film coating process for a container house with a radiation cooling film, including the following steps:

[0059] S1. Ensure the substrate is clean, dust-free, and rust-free before construction.

[0060] S2. Stir the paint evenly and adjust the viscosity of the paint according to the coating tools and environment on site. If the viscosity is too high, dilute it with deionized water or purified water. The dilution ratio should be less than 10%. After stirring evenly, filter it with a filter screen.

[0061] S3. Use air atomization spraying, high-pressure airless spraying, brushing or roller coating.

[0062] S4. Two coats are required for application. The first coat should not be too thick, with a dry film thickness not exceeding 40 micrometers. The drying time should be no less than 30 minutes. The second coat can only be applied after the film is completely dry to the touch and free of any stickiness. After coating, the dry film thickness should be maintained at 100-150 micrometers. This coating process can improve the performance of the radiation cooling film.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless defined as herein.

[0064] The meaning of "and / or" as used in this application includes situations where each exists alone or both exist simultaneously.

[0065] The term "connection" as used in this application can mean a direct connection between components or an indirect connection between components through other components.
