Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, and in particular to a test equipment storage panel structure and a fixed connection structure between the storage panel and the plant. Background Technology

[0002] To better meet the testing needs of ultra-large specimens for durability, lifespan, and aging verification under real natural environmental conditions, and to provide test basis for further performance analysis, correction, and optimization design of ultra-large specimens, ultra-large testing equipment is currently used to simulate natural environments such as high temperature, low temperature, and humidity to achieve temperature and humidity simulation tests.

[0003] It should be noted that ultra-large specimens can be specimens with large external dimensions, or a batch of specimens composed of multiple specimens with a large volume. Ultra-large specimens must have at least two of their length, width, and height exceeding 13m. Ultra-large testing equipment refers to testing equipment where the length, width, and height of the testing chamber all exceed 15m.

[0004] For ultra-large test equipment, depending on the test requirements, its interior needs to simulate high and low temperature and humid heat environment. At this time, the chamber of ultra-large test equipment (i.e., the tank chamber, or simply the chamber) is too large in volume and the temperature difference between the inside and outside of the chamber is large. The chamber of ultra-large test equipment is very prone to local deformation, which affects the overall sealing performance of the chamber and thus affects the reliability of the test.

[0005] Therefore, there is an urgent need to develop a technology that can solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to address the technical deficiencies of the existing technology by providing a storage plate structure for a testing equipment and a fixed connection structure between the storage plate and the factory building.

[0007] Therefore, this utility model provides a tray structure for a test device, which includes at least one tray unit that is a hexahedron;

[0008] The storage unit is a hollow, sealed shell;

[0009] The storage unit has an inner plate on the side facing the inner cavity of the testing equipment and an outer plate on the other side away from the inner cavity of the testing equipment.

[0010] Inner and outer panels are spaced apart;

[0011] The inner cavity of the panel unit is equipped with a polyurethane foam layer;

[0012] Of the remaining sides of the panel unit, excluding the inner and outer panels, at least two sides have concave portions and / or convex portions.

[0013] The lower sides of the concave and convex portions are provided with folded edges that protrude downwards;

[0014] An embedded hook lock is provided at the center of both the concave and convex parts;

[0015] Two embedded hook locks are located inside the cavity of the warehouse unit;

[0016] The inner panel has multiple nails on the side facing the outer panel;

[0017] Each nail has a limit baffle at the end furthest from the inner panel.

[0018] In addition, this utility model also provides a fixed connection structure between the warehouse panel and the factory building, which includes the roof beam of the factory building;

[0019] The roof beam of the factory building is connected to a panel unit in the panel structure of the test equipment as described above.

[0020] In addition, this utility model also provides another fixed connection structure between the warehouse panel and the factory building, which includes the factory building side beams;

[0021] The side beams of the factory building are connected to one side of the two panel units included in the panel structure of the test equipment as described above.

[0022] As can be seen from the technical solution provided by this utility model above, compared with the prior art, this utility model provides a tank plate structure for a test equipment and a fixed connection structure between the tank plate and the factory building. The structure is scientifically designed and applied to ultra-large test equipment. When the interior of ultra-large test equipment needs to simulate high and low temperature and humid heat environment, it can avoid the problem of local deformation of the tank body of ultra-large test equipment, ensure the overall sealing performance of the tank body, and thus ensure the reliable conduct of the test, which has great practical significance.

[0023] Furthermore, by applying this utility model, it is also beneficial to solve the problems that are very likely to occur in the tank body of test equipment (i.e., the tank body of test equipment that needs to simulate high and low temperature and humid heat environment) during construction and use, such as local deformation of the tank body, delamination of the tank body, and insufficient overall strength of the tank body.

[0042] Example 1.

[0043] See Figures 1 to 4 This utility model provides a test equipment panel structure, which is applied to the test equipment panel body (i.e., the test equipment panel body that needs to simulate high and low temperature and humidity environment), and includes at least one panel unit 1 as a hexahedron;

[0044] The storage unit 1 is a hollow, sealed shell;

[0045] The storage unit 1 has an inner plate 12 on the side facing the inner cavity of the storage chamber of the test equipment, and an outer plate 13 on the other side away from the inner cavity of the storage chamber of the test equipment.

[0046] Inner panel 12 and outer panel 13 are distributed at intervals;

[0047] It should be noted that the inner panel 12 is located inside the chamber of the testing equipment; the outer panel 13 is located outside the chamber of the testing equipment.

[0048] The inner cavity of the panel unit 1 is provided with a polyurethane foam layer 14;

[0049] Of the remaining sides of the panel unit 1, excluding the two sides where the inner and outer panels are provided, at least two sides are provided with recessed portions 21 and / or protruding portions 20.

[0050] A folded edge 16 is provided on the lower side of the concave portion 21 and the convex portion 20, protruding downwards;

[0051] It should be noted that, for example, see [link to relevant documentation]. Figure 1 , Figure 2 As shown, for a panel unit 1 located at the edge of one wall of the warehouse, concave portions 21 and convex portions 20 are respectively provided on its left and right sides, and a concave portion 21 is provided on its front side. Folded edges 16 are provided on the lower sides of the two concave portions 21 and the lower side of the convex portion 20. See also... Figure 9 , Figure 10 As shown, for a panel unit 1 located at the center of one wall of the warehouse, the left and right sides of the panel unit 1 can be provided with an inner concave part 21 and an outer convex part 20 respectively, and the front and rear sides can be provided with an inner concave part 21 and an outer convex part 20 respectively.

[0052] An embedded hook lock 15 is provided at the center of the concave part 21 and the convex part 20 respectively;

[0053] Two embedded hook locks 15 are located in the inner cavity of the warehouse unit 1;

[0054] The inner panel 12 has a plurality of (e.g., two) nails 17 on the side facing the outer panel 13;

[0055] Each nail 17 has a limit baffle 19 at the end away from the inner plate 12.

[0056] In this utility model, specifically, for the panel unit 1, the inner panel 12 is coated with a layer of high-temperature resistant adhesive 18 (specifically, a high-temperature resistant adhesive) on the side facing the outer panel 13 (i.e., the foamed surface, or the inner side).

[0057] It should be noted that the high-temperature adhesive 18 is an adhesive whose bonding performance does not fail at high temperatures (e.g., +120℃). It is used to firmly bond the inner panel 12 to the polyurethane foam layer 14. Any adhesive that meets this requirement is acceptable. It is a conventional adhesive and will not be described in detail here.

[0058] In this utility model, specifically, for the panel unit 1, the central axis of the folded edge 16 is perpendicular to the central axis of the embedded hook lock 15.

[0059] In this utility model, specifically, for the panel unit 1, the central axes of the two embedded hook locks 15 are located on the same straight line.

[0060] In this utility model, specifically, the polyurethane foam layer 14 fills the remaining gap in the inner cavity of the panel unit 1 (the remaining space in the inner cavity of the panel unit 1, excluding the space occupied by the embedded hook lock 15, high-temperature resistant adhesive 18, nail 17 and limiting baffle 19, i.e., the remaining gap).

[0061] It should be noted that, in this utility model, the function of the polyurethane foam layer 14 is to provide thermal insulation and break cold bridges, preventing heat transfer between the internal and external environments of the test chamber (i.e., the storage chamber used to install test equipment), thereby ensuring the thermal insulation function of the test chamber.

[0062] In practice, the embedded hook lock 15 is divided into two types: male and female. The male type embedded hook lock 15 and the female type embedded hook lock 15 are installed on the outer protrusion 20 and inner concave part 21 of the warehouse body, respectively. When the outer protrusion and inner concave parts of the two warehouse panel units are spliced, the nut in the male type embedded hook lock 15 is rotated so that the hook on it is hooked on the female type embedded hook lock 15 to realize the connection at the splicing point of the two warehouse panel units.

[0063] In this utility model, specifically, the embedded hook lock 15 is a mature connector with existing technology. For example, the YL-1168 model of the eccentric buckle produced by Yuhuan Yulong Refrigeration Machinery Factory can be used. This component can be used for connection and fixation at the joint when splicing the warehouse unit.

[0064] In this utility model, specifically, the inner plate 12 can be a stainless steel plate with a thickness of 1.5mm, because the inner plate 12 is located inside the test chamber (i.e., the storage body used to install test equipment). The environment inside the test chamber involves high temperature and high humidity. Using a stainless steel plate can prevent rusting.

[0065] In practice, the outer plate 13 can be a cold-rolled steel plate with a thickness of 1.5mm, and the surface of the steel plate is powder-coated to ensure the anti-static performance of the outer plate and the overall aesthetics of the test chamber.

[0066] In this utility model, specifically, the inner plate 12 has a stud 17 welded to its inner side facing the outer plate 13 by a spot welding process, and a high-temperature resistant adhesive 18 is applied to the inner side of the inner plate 12 to increase the adhesion of this surface.

[0067] In practice, a limiting baffle 19 is installed on the nail 17 by bolts;

[0068] In practice, the limiting baffle 19 can be made of a heat-insulating and high-strength epoxy resin board;

[0069] It should be noted that for each panel unit 1, after the polyurethane foam layer 14 inside it completes the foaming process, the surface where the high-temperature resistant adhesive 18 contacts the polyurethane foam layer 14 can form a high-strength area on the whole surface. At the same time, the limiting baffle 19 embedded inside the polyurethane foam layer 14 further provides the inner panel 12 with anti-detachment tension, which can greatly avoid local deformation caused by thermal expansion and contraction of the inner panel 12, and avoid the situation where the inner panel 12 separates from the insulation layer (i.e., the polyurethane foam layer 14).

[0070] It should be noted that the anti-detachment phenomenon is a phenomenon, and the root cause is the deformation of the tank body. For example, when conducting high and low temperature tests in the test chamber, the inner panel 12 is prone to local bulging, which in turn causes the inner panel 12 to detach from the polyurethane foam layer 14.

[0071] It should be noted that the reason why the inner panel 12 is able to be pulled apart is twofold: firstly, the surface of the inner panel 14 is coated with high-temperature resistant adhesive 18, which increases the connection between the inner panel 12 and the polyurethane foam layer 14, making it easier to form a whole and not easy to be pulled apart; secondly, the inner panel 12 is welded with nails 17, and the top of the nails 17 is fixed with a limiting baffle 19, which further increases the connection between the inner panel 12 and the polyurethane foam layer 14.

[0072] In this invention, when the panel structure includes multiple panel units 1, for any two panel units 1 that need to be connected, the protruding part 20 on one panel unit 1 is spliced ​​with the concave part 21 on the other panel unit 1, and a high and low temperature resistant sealing silicone is applied to the contact surface between the two to achieve sealing and bonding; therefore, the sealing performance of the joint between the two panel units can be guaranteed.

[0073] When three panel units 1 need to be spliced ​​together, the outward protrusion 20 on the first panel unit 1 is spliced ​​with the inward concave portion 21 on the second panel unit 1, and the inward concave portion 2 on the first panel unit 1 is spliced ​​with the outward protrusion 20 on the third panel unit 1.

[0074] In this utility model, specifically, when the warehouse panel structure includes multiple warehouse panel units 1, for any two warehouse panel units 1 that need to be connected, an outer mounting plate 3 is covered (e.g., welded) at the joint of the outer panels 13 on the two warehouse panel units.

[0075] In this utility model, specifically, when the warehouse panel structure includes multiple warehouse panel units 1, for any two warehouse panel units 1 that need to be spliced, the folded edge 16 on the outer protrusion 20 of one warehouse panel unit 1 is seamlessly welded to the folded edge 16 on the inner concave part 21 of the other warehouse panel unit 1.

[0076] In this utility model, specifically, when the warehouse panel structure includes multiple warehouse panel units 1, for any two warehouse panel units 1 that need to be spliced, the embedded hook lock 15 on the outer protrusion 20 of one warehouse panel unit 1 is connected to the embedded hook lock 15 on the inner concave part 21 of the other warehouse panel unit 1.

[0077] It should be noted that, for any two warehouse panel units 1 that need to be spliced, when assembling the two warehouse panel units 1, the embedded hook locks 15 on both of them are locked and connected, thereby increasing the overall connection reliability of the two warehouse panel units 1.

[0078] In this utility model, specifically, when the panel structure includes multiple panel units 1, for any two panel units 1 that need to be spliced, the folded edge 16 on the outer protrusion 20 of one panel unit 1 and the folded edge 16 on the inner concave part 21 of the other panel unit 1 are seamlessly welded by using TIG (Tungsten Inert Gas Welding) welding method.

[0079] It should be noted that, for any two warehouse panel units 1 that need to be spliced, the expansion and contraction edges 16 at the inner panels 12 of the two warehouse panel units will be fully welded with TIG seamless welding. On the one hand, this makes the connection between the two warehouse panel units firm and effectively prevents the expansion and cracking problem that occurs under high and low temperatures. On the other hand, after full welding, an expansion joint can be formed here, which can effectively eliminate the local stress caused by the thermal expansion and contraction deformation of the inner panels of the warehouse panel units, thereby avoiding the occurrence of local deformation.

[0080] It should be noted that expansion joints are the recessed parts at the joint of two warehouse panel units. Their main function is to release the stress in the inner panel of the warehouse panel unit and prevent the warehouse panel unit from undergoing plastic deformation.

[0081] The basic structure of the expansion joint is a bevel formed by bending sheet metal around the edges of the warehouse panel unit. It is called an expansion joint because of its function. When two adjacent warehouse panel units are fully welded, the inner panel will have welding stress that needs to be released. The expansion and folding edge 16 obtained by bending sheet metal has both a certain strength and a certain amount of adjustability, which can release the stress of the inner panel during welding, thereby preventing deformation of the warehouse unit and the entire warehouse.

[0082] Example 2.

[0083] Based on the panel structure provided by this utility model, see [link / reference]. Figure 5 , Figure 6 As shown, this utility model also provides a fixed connection structure between the warehouse panel and the factory building, specifically a fixed connection structure between the warehouse panel and the roof beam of the factory building, which is applied to the warehouse body (i.e., the warehouse panel compartment) of the test equipment, and the warehouse body of the test equipment is located in a factory building;

[0084] The fixed connection structure between the warehouse panels and the factory building includes the factory building's roof beam 4;

[0085] The factory roof beam 4 is connected to a panel unit 1 in the panel structure of the test equipment as described above;

[0086] In this utility model, specifically, the connection between the roof beam 4 of the factory building and the panel unit 1 in the panel structure of the testing equipment is designed as follows:

[0087] The roof beam 4 of the factory building is connected to one end of the turnbuckle 6 via the second threaded rod 8;

[0088] The other end of the turnbuckle 6 is connected to one end of the first lead screw 7;

[0089] The other end of the first lead screw 7 is connected to a panel unit 1 in the panel structure of the test equipment;

[0090] The first lead screw 7 is located on the outer side of the portion between the turnbuckle 6 and the outer plate 13 of the panel unit 1, and is fitted with an insulation sleeve 9.

[0091] In practice, the upper end of the second lead screw 8 is threadedly fixed to a nut 2 after passing through the first through hole reserved on the roof beam 4 of the factory building.

[0092] The lower end of the second lead screw 8 is threadedly fixed to the threaded hole reserved at the upper end of the turnbuckle 6;

[0093] In practice, the upper end of the first lead screw 7 is threadedly fixed to the threaded hole reserved at the lower end of the turnbuckle 6;

[0094] The lower end of the first lead screw 7 passes through the second through hole reserved on the panel unit 1 and is threadedly fixed to two nuts 2.

[0095] Furthermore, the first lead screw 7 is threadedly fixed to two nuts 2, and these two nuts 2 are distributed on the inner and outer sides of the panel unit 1;

[0096] One nut 2 is connected to the lower end of the first lead screw 7 and is in tight contact with the outer surface of the inner plate 12 of the storage unit 1. The other nut 2 is connected to the middle section of the first lead screw 7 and is in tight contact with the outer surface of the outer plate 13 of the storage unit 1. Therefore, the first lead screw 7 can be reliably fixed to the inner and outer sides of the storage unit 1 by means of the two nuts 2 distributed inside and outside.

[0097] In practice, the insulation sleeve 9 is fitted over the outer side of the portion of the first lead screw 7 located between the turnbuckle 6 and the outer plate 13 of the panel unit 1.

[0098] It should be noted that the insulation sleeve 9 is installed on the outer surface of the first lead screw 7, and covers and conceals the entire visible length of the first lead screw 7. Since the entire visible length of the first lead screw 7 between the outer plate 13 and the turnbuckle 6 is enclosed within the insulation sleeve 9, heat insulation can be achieved between the inside and outside of the chamber of a test equipment (i.e., the chamber panel).

[0099] In practice, the overall shape of the factory roof beam 4 is "I" shaped and it is laid flat.

[0100] Example 3.

[0101] Based on the panel structure provided by this utility model, see [link / reference]. Figure 7 , Figure 8 As shown, this utility model also provides a fixed connection structure between the warehouse panel and the factory building, specifically a fixed connection structure between the warehouse panel and the side beam of the factory building, which is applied to the warehouse body (i.e., the warehouse panel compartment) of the test equipment, and the warehouse body of the test equipment is located in a factory building;

[0102] The fixed connection structure between the warehouse panel and the factory building includes the factory building side beam 5;

[0103] The side beam 5 of the factory building is connected to one side of the two panel units 1 included in the panel structure of the test equipment as described above;

[0104] In this utility model, specifically, the two panel units 1 in the panel structure of the test equipment are stacked one on top of the other.

[0105] In this utility model, specifically, the connection between the side beam 5 of the factory building and the two panel units 1 in the panel structure of the testing equipment is designed as follows:

[0106] The two outer plates 13 of the two panel units 1 of the panel structure of the test equipment are simultaneously connected to one side of the fixed plate 11;

[0107] The other side of the fixing plate 11 is connected to the first contact surface on the connecting bracket 10;

[0108] The second contact surface on the connecting bracket 10 is connected to one side (specifically, the upper side) of the factory building side beam 5;

[0109] The first contact surface and the second contact surface on the connecting bracket 10 are two planes that are vertically intersecting;

[0110] Specifically, the other side of the fixing plate 11 is welded to the first contact surface on the connecting bracket 10;

[0111] The second contact surface on the connecting bracket 10 is welded to one side (specifically, the upper side) of the factory building side beam 5.

[0112] Specifically, the fixing plate 11 is riveted and fixed to the two outer plates 13 in the two panel units 1 included in the panel structure of the test equipment;

[0113] Further, the fixing plate 11 is riveted and fixed to the two outer plates 13 in the two panel units 1 included in the panel structure through four blind rivets.

[0114] Specifically, the overall shape of the factory building side beam 5 is an "I" shape.

[0115] It should be noted that the outer mounting plate 3 is not installed in the area covered by the fixing plate 11 to ensure the close fit of the fixing plate 11 and the outer plate 13. After the two panel units 1 are assembled and leveled, the connecting bracket 10 is positioned and welded according to the actual distance between the outer plate 13 and the factory building side beam 5, and the connecting bracket 10 is welded to the fixing plate 11 and the factory building side beam 5 respectively.

[0116] Embodiment 4.

[0117] Based on the above-mentioned panel structure provided by the present utility model, the present utility model also provides a library body, which is used as the library body (i.e., the panel cabin) of the test equipment, and it includes a plurality of panel structures of the test equipment as described above;

[0118] In the present utility model, specifically, for any panel structure, the concave part 21 of one panel unit 1 thereof is connected to the convex part 20 of one panel unit 1 of the adjacent panel structure.

[0119] It should be noted that the specific connection method between the two panel units 1 in the two panel structures is the same as the connection method between the adjacent two panel units 1 in the panel structure of one test equipment as described above, and will not be elaborated here.

[0120] In the present utility model, specifically, the library body (i.e., the panel cabin) of the test equipment is located in a factory building.

[0121] In the present utility model, specifically, the library body (i.e., the test cabin) of the test equipment is a hollow and sealed library body.

[0122] It should be noted that, for this utility model, see [link to relevant documentation]. Figure 9 , Figure 10 As shown, when multiple panel units 1 are needed to form one wall of the test equipment's housing (i.e., the test chamber) (e.g., a vertically distributed wall, which is usually the side wall of the test chamber), the structural design of any panel unit 1 can include the following three cases:

[0123] First, if there are other panel units 1 to be spliced ​​on the front, back, left, and right sides of the panel unit 1 (for example, the panel unit located in the center), then the panel unit 1 includes six surfaces: inner panel 12, outer panel 13, two protruding parts 20 (distributed on two surfaces), and two concave parts 21 (distributed on two surfaces).

[0124] Second, if the panel unit 1 has three surfaces that need to be connected to other panel units 1, then one of the protruding or concave parts of the panel unit 1 is adjusted to be flat, and the material of the flat part is the same as that of the outer panel 13.

[0125] Third, if the warehouse panel unit 1 has two surfaces that need to be connected with other warehouse panel units 1, then two of the protruding or concave parts of the warehouse panel unit 1 are adjusted to be flat, and the material of the flat surface is the same as that of the outer panel 13.

[0126] In summary, the connection between the storage panels on the test equipment's storage body (i.e., the storage panel compartment) and the factory roof beam 4 and factory side beam 5 of this utility model has flexible adjustable spacing. Due to the large assembly tolerances in the assembly of ultra-large storage bodies and the construction of the factory, uneven spacing between the storage body's roof and side panels and the factory roof and side beams may occur. This connection method can adjust the installation spacing, effectively offsetting the tolerances in the construction of ultra-large storage bodies and factory buildings. Furthermore, it utilizes the existing steel beams of the factory (i.e., factory roof beam 4 and factory side beam 5) to strengthen the overall structure of the storage body, greatly reducing manufacturing costs.

[0127] It should be noted that, for this utility model, when applied to the tank body of the test equipment (i.e., the tank body of the test equipment that needs to simulate high and low temperature and humidity environment), due to the large internal volume of the large tank body and the large temperature difference between the inside and outside of the tank body, the ultra-large tank body is very prone to problems such as local deformation of the tank body, delamination of the tank body, and insufficient overall strength of the tank body during construction and use.

[0128] To address the issue of localized deformation of the cold storage panels, a splicing structure consisting of multiple cold storage panel units can be used. Each cold storage panel unit is equipped with an expansion joint formed by welding the folded edge. When the inner panel of the cold storage panel unit undergoes thermal expansion and contraction deformation, causing localized stress, the expansion joint can effectively eliminate the stress, thereby preventing localized deformation.

[0129] To address the issue of warehouse panel detachment, a layer of high-temperature resistant adhesive is applied to the inner panel of the warehouse panel unit before polyurethane foaming, which increases the adhesion of the inner panel. In addition, this invention also uses spot welding and nailing to install a limiting baffle on the inner panel of the warehouse panel unit. After the polyurethane foaming is completed, the limiting baffle can provide a certain tensile force to the inner panel, thereby effectively preventing the warehouse panel from detaching.

[0130] Regarding the issue of overall strength of the warehouse structure, this utility model can utilize the existing steel beams of the factory building (i.e., the factory building roof beam 4 and the factory building side beam 5) to enhance the strength of the warehouse structure after installation. Based on the above design, it can offset the manufacturing tolerances of the warehouse panels and factory building structure, flexibly meet the tolerance requirements of the installation position, and greatly save manufacturing costs compared with traditional installation methods.

[0131] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
