Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, in particular to a thermal insulation board. Meanwhile, the utility model also relates to an energy storage container using the thermal insulation board. Background Art

[0002] The energy storage container system is a new energy device that stores a large number of energy storage lithium batteries in a container to perform peak shaving and valley filling, frequency modulation and other functions. It has the advantages of easy installation, easy transportation and modularization. Since the lithium batteries inside the energy storage container are flammable and explosive, the container body needs to have sufficient structural strength to play a protective role, and the container body also needs to play a heat preservation function inside during normal operation to ensure the performance of the lithium battery.

[0003] However, the wall panels of existing energy storage container bodies are generally made of outer corrugated steel plates, inner steel plates and middle insulating rock wool boards. Not only do they have the problem of insufficient structural strength, but also the problem that in order to ensure the insulation effect, the thickness of the insulating rock wool board cannot be well controlled, which occupies a lot of usable space inside the container, thereby affecting the overall use effect of the energy storage container system. Utility Model Content

[0004] In view of this, the utility model aims to provide a thermal insulation board with better structural strength and thermal insulation effect.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0008] Furthermore, the raised portion includes a plurality of raised units arranged at intervals along the extension direction of the middle layer plate, and each of the raised units is spaced apart from the outer layer plate.

[0009] Furthermore, the protruding dimension of the protruding unit is between 30 mm and 50 mm; and / or, along the extension direction of the middle plate, the spacing dimension between two adjacent protruding units is between 50 mm and 110 mm.

[0010] Furthermore, the distance between the outer plate and the inner plate is not less than 50 mm.

[0011] Furthermore, the thickness of the middle layer plate is between 1.6 mm and 2.0 mm; and / or the thickness of the outer layer plate and the inner layer plate are both between 1.0 mm and 2.0 mm.

[0016] Secondly, the raised part is mainly composed of a plurality of raised units, which is conducive to improving the structural strength of the middle layer board itself, and then enhancing the structural strength of the insulation board as a whole, and the spacing between each raised unit and the outer layer board is conducive to increasing the filling amount of the fireproof insulation material and ensuring the insulation effect of the insulation board. The protruding size of the raised unit is between 30mm-50mm, and the spacing between two adjacent raised units is between 50mm-110mm, which is conducive to achieving a better strength enhancement effect on the middle layer board.

[0017] In addition, the spacing between the outer and inner panels is not less than 50mm, which can prevent the fireproof insulation material from being too small and affecting the insulation effect. The thickness of the middle panel is between 1.6mm and 2.0mm, which is conducive to ensuring the structural strength of the middle panel. At the same time, the thickness of the outer and inner panels is between 1.0mm and 2.0mm, which is conducive to ensuring the structural strength of the two, thereby ensuring that the insulation board has sufficient structural strength.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Embodiment 1

[0036] This embodiment relates to an insulation board, which, compared with the insulation board used for energy storage containers in the prior art, can have better structural strength and insulation effect while controlling the total thickness of the board body.

[0037] In terms of overall structure, Figures 1 to 3 As shown, the thermal insulation board of this embodiment includes an inner layer board 11 and an outer layer board 13 which are connected by buckling, and a middle layer board 12 arranged between the inner layer board 11 and the outer layer board 13 .

[0038] Among them, the middle layer board 12 includes a main board body 121 and a protrusion arranged on the main board body 121. The protrusion is formed by protruding from the main board body 121 toward the outer layer board 13, and the gap between the inner layer board 11 and the middle layer board 12, and the gap between the middle layer board 12 and the outer layer board 13 are filled with fireproof and heat-insulating materials.

[0039] Specifically, in this embodiment, as an exemplary structure. Figure 1 and Figure 2 As shown, the raised portion includes a plurality of raised units 122 arranged at intervals along the extension direction of the middle plate 12 , and each raised unit 122 is spaced apart from the outer plate 13 .

[0040] Here, it can be understood that the raised portion is mainly composed of a plurality of raised units 122, which is conducive to improving the structural strength of the middle layer board 12 itself, thereby enhancing the overall structural strength of the insulation board, and the spacing between each raised unit 122 and the outer layer board 13 is not only conducive to the filling of fireproof insulation materials, but also conducive to increasing the filling amount, thereby ensuring the insulation effect of the insulation board.

[0041] When implementing it, refer to Figure 3 As shown, as a preferred implementation form, in this embodiment, the protruding dimension H of the protruding unit 122 is between 30 mm and 50 mm. At the same time, along the extension direction of the middle plate 12, the spacing dimension L1 between two adjacent protruding units 122 is between 50 mm and 110 mm.

[0042] The advantage of such a setting is that it is conducive to achieving a better strength enhancement effect on the middle layer plate 12 by controlling the specific structural dimensions of the middle layer plate 12, and H can be specifically taken as 30mm, 36mm, 45.6mm or 50mm, etc., and L1 can be specifically taken as 50mm, 80mm or 110mm, etc., so as to achieve a relatively optimal structural enhancement effect.

[0043] Furthermore, as a preferred implementation form, in this embodiment, the spacing dimension L2 between the outer layer plate 13 and the inner layer plate 11 is not less than 50 mm, and the specific value of L2 can be 50 mm, 60 mm or 70 mm, etc., so as to avoid the filling amount of fireproof insulation material being too small to affect the insulation effect, and at the same time, it can also control the overall thickness of the insulation board not to be too large, thereby enhancing the product competitiveness of the insulation board.

[0044] In addition, in this embodiment, as a preferred implementation form, the thickness of the middle plate 12 is between 1.6 mm and 2.0 mm, and the thickness of the outer plate 13 and the inner plate 11 are both between 1.0 mm and 2.0 mm.

[0045] The advantage of such a configuration is that it helps to ensure the structural strength of the middle plate 12, the outer plate 13 and the inner plate 11 by controlling the specific thickness dimensions, thereby ensuring that the insulation board has sufficient structural strength. In addition, combined with the specific structural setting and specific dimensional design of the above-mentioned raised portion, the insulation board can have good structural strength and safety.

[0046] Of course, in this embodiment, the thickness dimension of the layer plate 12 can be specifically 1.6mm, 1.8mm or 2.0mm, etc., and the thickness dimensions of the outer layer plate 13 and the inner layer plate 11 can be specifically 1.0mm, 1.5mm or 2.0mm, etc., so as to achieve a relatively optimal structural reinforcement effect.

[0047] In addition, in this embodiment, as a preferred implementation form, the fireproof thermal insulation material adopts rock wool or polyurethane thermal insulation material, so as to control the production cost of the thermal insulation board by taking advantage of the mature and easy-to-buy characteristics of rock wool or polyurethane thermal insulation materials.

[0048] At the same time, as a preferred implementation form, in this embodiment, the middle plate 12 is made of corrugated steel plate, and at the same time, the outer plate 13 and the inner plate 11 are made of steel plate. The advantage of this arrangement is that the overall strength of the structure can be improved by combining the corrugated steel plate with the two layers of steel plates, which is also beneficial for controlling the production cost of the insulation board.

[0049] Specifically, the insulation board of this embodiment can achieve good insulation and fire resistance by attaching a layer of steel plate to the inner and outer sides of the corrugated steel plate (i.e., the middle plate 12, the specific value can be 2mm), and using a layer of rock wool filling inside and outside the corrugated steel plate, and ensuring that the total thickness of the rock wool filling reaches 50mm. When an explosion occurs, the inner steel plate (i.e., the inner plate 11) first absorbs a part of the shock wave and transmits it to the inner corrugated steel plate. The folded corrugated steel plate has a high impact resistance and bears the main impact. When it is transmitted to the outer steel plate (i.e., the outer plate 13, it can play a good buffering role).

[0050] The insulation board of this embodiment can improve the overall structural strength of the insulation board by adding a middle layer board 12 between the inner layer board 11 and the outer layer board 13 and providing a protrusion on the middle layer board 12. At the same time, the gap between the inner layer board 11 and the middle layer board 12 and the gap between the middle layer board 12 and the outer layer board 13 are filled with fireproof insulation materials, which can ensure the insulation performance of the insulation board, thereby making the insulation board have better structural strength and insulation effect.

[0051] It is understandable that the insulation board of this embodiment, from the appearance, its inner layer bar and outer layer plate 13 are both flat plate structures, and the visual effect is more beautiful. In terms of performance, the overall thickness of the board can be reduced while ensuring the insulation effect, making the insulation board more competitive in the market, or the insulation board of this embodiment can adjust its own thickness and insulation performance according to demand, and can also have a certain degree of explosion-proof function based on the improvement of structural strength and insulation effect.

[0052] Embodiment 2

[0053] This embodiment relates to an energy storage container, in which the insulation board in the first embodiment is used. Figure 4 As shown, the energy storage container of this embodiment further includes a bottom plate 21, a top plate and a plurality of side plates 22, and at least the top plate and each side plate 22 are made of an insulation plate.

[0054] Therefore, the overall structural strength and thermal insulation effect of the energy storage container can be ensured on the basis that the thermal insulation board has both good structural strength and thermal insulation effect.

[0055] At the same time, this embodiment also relates to an energy storage system, in which the above-mentioned energy storage container is configured. It is worth mentioning that the energy storage container in this embodiment mainly refers to a box for assembling electrical components such as battery packs, battery management systems, energy storage converters, inverters and distribution cabinets.

[0056] If necessary, the energy storage system of this embodiment can be understood as a containerized energy storage system, that is, including an energy storage container and electrical components such as a battery pack, a battery management system, an energy storage converter, an inverter, and a distribution cabinet.

[0057] The energy storage container and energy storage system of this embodiment, by setting the insulation board in Example 1, can utilize the advantages of the insulation board in having both good structural strength and insulation effect, improve the structural strength and insulation effect of the entire structure, and thus have better performance.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
