Description

Technical Field

[0001] The utility model relates to the technical field of safety protection of energy storage equipment, and in particular to an energy storage equipment box. Background Art

[0002] The safety protection design of energy storage battery systems has always been a key concern of the industry. With the continuous development of the energy storage market, fires in energy storage equipment boxes occur from time to time. However, since energy storage power stations are generally located in remote areas, when a fire occurs, it will take longer for firefighters to arrive at the scene. In order to ensure the personal and property safety of customers, it is necessary to design the energy storage equipment box to be fire-resistant and heat-insulated to reduce the impact of the fire to only affect a single equipment compartment and prevent it from spreading to other equipment compartments.

[0003] In order to solve the above problems, the prior art usually adopts a box structure with fireproof insulation board to block the heat flow in a single equipment compartment and avoid the thermal bridge effect, so as to improve the fire resistance and heat insulation performance of a single equipment compartment. However, due to the large size of the energy storage equipment box, the overall size of the fireproof insulation board also needs to be large, resulting in high processing costs and difficulty in installation and transportation of the fireproof insulation board. For this problem, the prior art often adopts a multi-section splicing method to realize the splicing and forming of the insulation board or insulation layer, but the splicing is prone to unreliable splicing or poor heat shielding effect at the splicing position, resulting in heat leakage and even loss of fire resistance of the corresponding equipment compartment. Utility Model Content

The two surfaces of the limiting protrusion used for matching and the end faces of the main body that avoid the limiting protrusion respectively form multiple matching surfaces, and the two limiting protrusions of any two refractory heat-insulating materials at the splicing position overlap in the thickness direction of the main body, and n=3.

[0010] Furthermore, the limiting protrusion is a rectangular protrusion, one limiting protrusion is provided at one end of the main body, and two limiting protrusions are provided at the other end of the main body.

At the same time, such a setting is conducive to reducing the situation where the two adjacent refractory insulation materials of the insulation layer are easily deformed at high temperatures, causing the joint to become larger or misaligned, and then causing the insulation effect to fail, which is conducive to improving the reliability, stability and safety of the fireproof insulation of the energy storage equipment box, and is conducive to reducing the impact on other equipment compartments when a single equipment compartment catches fire and ensuring the safety of the staff.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0042] like Figures 1 to 13 As shown, an embodiment of the utility model provides an energy storage device box, which includes a box structure 11 and a plurality of partitions 12, wherein the plurality of partitions 12 are arranged at intervals in the box structure 11 and divide the interior of the box structure 11 into a plurality of sequentially spaced equipment compartments, the box structure 11 and / or the partitions 12 have an insulation layer 101, and the insulation layer 101 is formed by splicing a plurality of sections of refractory heat-insulating materials 1011, and both ends of the refractory heat-insulating materials 1011 have splicing surfaces 108, and the two opposite splicing surfaces 108 of any two adjacent sections of refractory heat-insulating materials 1011 are bonded to each other, and the area of ​​the splicing surface 108 of the refractory heat-insulating materials 1011 is greater than the cross-sectional area of ​​the refractory heat-insulating materials 1011 in the thickness direction; wherein the splicing surface 108 includes n mating surfaces 1081, n is a positive integer, at least one mating surface 1081 is an arc-shaped curved surface, or at least one mating surface 1081 is a plane inclined relative to the thickness direction of the refractory heat-insulating material 1011.

[0043] In this embodiment, by setting up a heat insulation layer 101, it is prevented that when a certain equipment compartment of the energy storage equipment box catches fire, the heat is easily transferred to other equipment compartments and then affects the equipment in other equipment compartments, and the impact caused by the fire is reduced to only affect a single equipment compartment, and will not spread to other equipment compartments. The thermal layer is formed by splicing multiple sections of fire-resistant heat-insulating materials 1011, which avoids the situation in the prior art that the overall size of the fireproof insulation board needs to be adapted to the size of the energy storage equipment box, resulting in high processing costs and difficult installation and transportation of the fireproof insulation board. The operator assembles a heat insulation layer 101 of a suitable size in the partition 12 and / or the box structure 11 on the periphery of the equipment compartment that needs to be insulated according to the actual situation, so as to improve the convenience of processing and setting of the heat insulation layer 101 and reduce the processing and transportation costs on the basis of ensuring the heat insulation effect of the equipment compartment. On the other hand, the joint surface 108 of any two adjacent sections of refractory heat-insulating material 1011 is limited to ensure the reliability and stability of the joints between the refractory heat-insulating materials 1011, and to avoid the situation where heat easily overflows from the joint position. Furthermore, by limiting the area of ​​the joint surface 108 and limiting the setting of the matching surface 1081, it is beneficial to improve the blocking effect of the overflowing heat and extend the heat overflow path, and avoid the situation where the joint formed by the joint surface 108 of two adjacent sections of refractory heat-insulating material 1011 is parallel to the thickness direction of the insulation layer 101, and the heat easily overflows from the equipment compartment vertically along the joint, thereby reducing the heat transferred through the joint and improving the refractory and heat-insulating performance of the energy storage equipment box. At the same time, such a configuration is conducive to reducing the situation where two adjacent refractory insulation materials 1011 of the insulation layer 101 are easily deformed at high temperatures, causing the joints to become larger or misaligned, and then causing the insulation effect to fail. It is conducive to improving the reliability, stability and safety of the fire-resistant insulation of the energy storage equipment box, and is conducive to reducing the impact of a single equipment compartment on other equipment compartments when a fire occurs and ensuring the safety of the staff.

[0044] Specifically, the multiple sections of refractory heat-insulating materials 1011 of the heat-insulating layer 101 have the same shape, and the joints 108 of any two adjacent sections of refractory heat-insulating materials 1011 are in the same shape. This arrangement facilitates the processing of multiple refractory heat-insulating materials 1011 and the splicing of the heat-insulating layer 101. It is understandable that in other embodiments not shown in the figure, the multiple sections of refractory heat-insulating materials 1011 used to form the heat-insulating layer 101 may not be completely the same, and can be adaptively arranged according to the refractory heat-insulating performance required by different equipment compartments.

[0045] It is understandable that the limiting protrusion 10112 and the main body 10111 are integrally arranged, and the staff can obtain the required limiting protrusion 10112 by cutting and other processing on both ends of the refractory insulation material 1011.

[0046] Further, the refractory heat-insulating material 1011 includes a main body 10111 and limiting protrusions 10112 arranged at both ends of the main body 10111. The limiting protrusion 10112 located at one end of the refractory heat-insulating material 1011 and the limiting protrusion 10112 at one end of the refractory heat-insulating material 1011 adjacent thereto are limitedly matched, and the surface of the limiting protrusion 10112 used for matching forms a matching surface 1081; or, the limiting protrusion 10112 located at one end of the refractory heat-insulating material 1011 and the limiting protrusion 10112 at one end of the refractory heat-insulating material 1011 adjacent thereto and the end face of the main body 10111 are limitedly matched, and the surface of the limiting protrusion 10112 used for matching and the end face of the main body 10111 used for matching both form a matching surface 1081. With such arrangement, the limiting protrusion 10112 facilitates the design of the joint surface 108 of the refractory heat-insulating material 1011, and a special-shaped structure is made at the joint of different pieces of refractory heat-insulating material 1011, so that two adjacent refractory heat-insulating materials 1011 can be closely matched with each other, thereby increasing the mutual contact area at the joint and the length and complexity of the heat transfer path, and preventing heat from being directly conducted to the outside of the cabin through the joint. This is beneficial to ensuring and improving the refractory heat-insulating effect of the energy storage equipment box on the basis of improving the splicing efficiency of the insulation layer 101.

[0047] In such Figures 4 to 7 In the illustrated embodiment 1, a limiting protrusion 10112 is respectively provided at both ends of the main body 10111, and the two limiting protrusions 10112 are symmetrically arranged relative to the center of the main body 10111, and the cross-sectional shape of the limiting protrusion 10112 is a right triangle, the inclined surface of the right triangle forms a mating surface 1081, and the two ends respectively extend to the two side planes in the thickness direction of the main body 10111, and when two adjacent refractory heat-insulating materials 1011 are spliced, the two limiting protrusions 10112 of any two refractory heat-insulating materials 1011 at the splicing position overlap in the thickness direction of the main body 10111, and n=1.

[0048] In this embodiment, the joint surface 108 is formed by a matching surface 1081, which is the inclined surface of the limiting protrusion 10112 with a right triangle cross section, and the inclined surface is inclined relative to the cross section of the fire-resistant heat-insulating material in the thickness direction. This arrangement is conducive to improving the blocking effect of the joint position on the overflow heat and extending the heat overflow path, reducing the heat transferred through the joint, and improving the fire resistance and heat insulation of the energy storage device box.

[0049] In such Figures 8 to 10In the second embodiment shown, a limiting protrusion 10112 is respectively provided at both ends of the main body 10111, and the two limiting protrusions 10112 are symmetrically arranged relative to the center of the main body 10111, the limiting protrusion 10112 is a rectangular protrusion, one side of the rectangular protrusion in the thickness direction of the refractory heat-insulating material 1011 is flush with one side of the main body 10111 in the thickness direction of the refractory heat-insulating material 1011, the other side of the rectangular protrusion in the thickness direction of the refractory heat-insulating material 1011 is spaced from the other side of the main body 10111 in the thickness direction of the refractory heat-insulating material 1011, the two surfaces of the limiting protrusion 10112 for matching and the end faces of the main body 10111 that avoid the limiting protrusion 10112 respectively form a plurality of matching surfaces 1081, and the two limiting protrusions 10112 of any two refractory heat-insulating materials 1011 at the splicing position overlap in the thickness direction of the main body 10111, and n=3.

[0050] In this embodiment, the joint surface 108 is formed by three matching surfaces 1081, wherein two matching surfaces 1081 are respectively the end surface of the rectangular protrusion and the surface of one side parallel to the refractory heat-insulating material 1011 but not flush therewith, and the other matching surface 1081 is the end surface of the rectangular protrusion that avoids the refractory heat-insulating material 1011 in the thickness direction, wherein the matching surface 1081 formed by the surface of one side parallel to the refractory heat-insulating material 1011 but not flush therewith is parallel to the surface of one side of the refractory heat-insulating material 1011 in the thickness direction and perpendicular to the other two matching surfaces 1081. Such a setting is conducive to improving the blocking effect of the joint position on the overflow heat and extending the heat overflow path, reducing the heat transferred through the joint, and improving the fire resistance and heat insulation of the energy storage device box.

[0051] In such Figures 11 to 13 In the third embodiment shown, the limiting protrusion 10112 is a rectangular protrusion, one end of the main body 10111 is provided with a limiting protrusion 10112, and the other end of the main body 10111 is provided with two limiting protrusions 10112, and the sides of the two limiting protrusions 10112 located on the same side that are opposite to each other are respectively flush with the two sides in the thickness direction of the main body 10111, and a limiting groove is formed between the two limiting protrusions 10112 located on the same side and the end face of the main body 10111, the limiting protrusion 10112 of any refractory heat-insulating material 1011 and the limiting groove of the adjacent refractory heat-insulating material 1011 are limitedly matched, and the three limiting protrusions 10112 of any two refractory heat-insulating materials 1011 at the splicing position overlap in the thickness direction of the main body 10111, and n=5.

[0052] In this embodiment, the joint surface 108 is formed by five matching surfaces 1081, and the rectangular surface is the surface where the plurality of limiting protrusions 10112 and the two main bodies 10111 cooperate or join with each other. This arrangement is conducive to improving the blocking effect of the joint position on the overflow heat and extending the heat overflow path, reducing the heat transferred through the joint, and improving the fire resistance and heat insulation of the energy storage device box.

[0053] It can be understood that the design purpose of the joint is mainly to avoid the straight edges of two adjacent refractory insulation materials 1011 from contacting each other, so that heat can be directly transferred out through the gap. The special-shaped design of the joint structure can increase the complexity of the heat transfer path and make the joint tighter. At the same time, it can also constrain the positions of the spliced ​​refractory insulation materials to each other, and resist the deformation of the wall due to heat causing the deformation of the refractory insulation materials, which may lead to the failure of the refractory insulation. Other splicing schemes that can achieve the above-mentioned purpose, such as designing the joint position to be wavy, arc-shaped, etc., can be applied. The splicing scheme is not limited to Examples 1 to 3 proposed in the utility model.

[0054] In this embodiment, the box structure 11 and / or the partition 12 is a double-layer structure with a filling area 102, and the heat insulation layer 101 is filled in the filling area 102 of the double-layer structure. The energy storage device box also includes a frame structure, which is arranged in the filling area 102 and is composed of a plurality of columns, and the plurality of columns are distributed on both sides of the heat insulation layer 101 and are respectively connected to the two side walls of the filling area 102. The frame structure plays the role of installation positioning and support and limit for the box structure 11, the partition 12, and the heat insulation layer 101, which is conducive to facilitating the processing and forming of the energy storage device box while ensuring the fire-resistant and heat-insulating performance of the energy storage device box.

[0055] like Figures 1 to 13 As shown, the double-layer structure consists of an inner wall 103 and an outer wall 104, a filling area 102 is formed between the inner wall 103 and the outer wall 104, a plurality of columns located between the inner wall 103 and the insulation layer 101 are inner columns 132, the inner wall 103 is welded to the inner columns 132, a plurality of columns located between the outer wall 104 and the insulation layer 101 are outer columns, the outer wall 104 is welded to the outer columns, and the inner columns 132 are separated from the outer columns by the insulation layer 101.

[0056] In this embodiment, when a fire occurs in a certain equipment compartment of the energy storage equipment box, the heat transfer path is the inner wall 103 of the equipment compartment → the inner column 132 → the middle insulation layer 101 → the outer column 131 → the outer wall 104, reducing the heat transferred from the inside of the equipment compartment to the outside through the joints, and ensuring the fire resistance and heat insulation performance of the equipment compartment. Furthermore, the inner column 132 is separated from the outer column 131 by the insulation layer 101, avoiding the situation where the inner column 132 and the outer column 131 are in direct contact and easily produce a "thermal bridge effect", thereby ensuring the fire resistance and heat insulation performance of the energy storage equipment box.

[0057] like Figure 6 , Fig. 9 and Fig.12 As shown, the inner wall surface 103 is composed of a plurality of sub-wall surfaces 1031, and a splicing position is formed between any two sub-wall surfaces 1031. The position where the splicing surfaces 108 of any two adjacent sections of refractory heat-insulating materials 1011 are attached to each other is a splicing position. When the splicing position is directly opposite to the splicing position in the thickness direction of the heat-insulating layer 101, an inner column 132 is arranged between the splicing position and the splicing position. This arrangement improves the supporting effect of the splicing of two adjacent sections of refractory heat-insulating materials 1011, avoids the situation where the splicing of the refractory heat-insulating materials 1011 is easy to loosen, resulting in the enlargement of the splicing seam and the reduction of the refractory heat-insulating effect, and ensures the reliability and stability of the splicing of the refractory heat-insulating materials 1011.

[0058] like Figure 5 , Figure 8 and Fig.11 As shown, the inner wall surface 103 is composed of a plurality of sub-wall surfaces 1031, and the position where the joint surfaces 108 of any two adjacent sections of refractory heat-insulating materials 1011 are attached to each other is the joint position, and when the joint position is directly opposite to one of the sub-wall surfaces 1031 in the thickness direction of the heat-insulating layer 101, inner side columns 132 are arranged on both sides of the joint position. This arrangement also improves the support for the joint position and the support effect for the joint of two adjacent sections of refractory heat-insulating materials 1011.

[0059] Specifically, the frame structure also includes a plurality of main columns 133, which are spaced apart on the side of the inner wall 103 away from the inner column 132. The inner wall 103 is composed of a plurality of sub-walls 1031. The main columns 133 are used to weld any two adjacent sub-walls 1031. In the width direction of the insulation layer 101, the plurality of outer columns and the plurality of main columns 133 correspond one to one.

[0060] In this embodiment, the inner wall 103 is welded with a plurality of inner columns 132 and a plurality of main columns 133 to form a complete inner wall, and the outer wall 104 is welded with a plurality of outer columns 131 to form a complete outer wall of the battery compartment. The heat insulation layer is filled between the inner and outer walls to reduce the diffusion of heat in the cabin to the outside. The arrangement of a plurality of main columns 133 facilitates the positioning and installation of the inner wall 103, and is also conducive to increasing the structural strength of the inner wall 103 after molding. Specifically, a plurality of outer columns 131 and a plurality of main columns 133 correspond one to one to ensure the support and positioning effect of the heat insulation layer 101.

[0061] Furthermore, the outer wall 104 is a corrugated plate wall and forms a plurality of spaced installation areas 1041 with the heat insulation layer 101, a plurality of outer columns are distributed in the plurality of installation areas 1041, and the outer wall 104 area between any two adjacent installation areas 1041 forms abutment sections, and the plurality of abutment sections are all in contact with the heat insulation layer 101. This arrangement is conducive to increasing the area of ​​the outer wall 104 and facilitating the installation of the outer columns 131, and the abutment sections are used to achieve the arrangement and contact of the plurality of heat insulation layers 101, thereby ensuring the positioning and installation effect of the outer wall 104 on the heat insulation layer 101.

[0062] Preferably, the inner circumferential direction of the outer wall 104 has an installation bend, the insulation layer 101 is located in the area surrounded by the installation bend and the outer wall 104, and the inner wall 103 is connected to the outer wall 104 through the installation bend and multiple main columns 133 to form a filling area 102.

[0063] Preferably, the frame structure is filled with fire-resistant heat-insulating material 1011. Such an arrangement is conducive to further improving the fire-resistant heat-insulating performance of the energy storage device box.

[0064] It is understandable that the refractory insulation material 1011 can be filled in different columns of the frame structure according to actual conditions, so as to reduce the overall refractory insulation design cost of the energy storage equipment box while ensuring the refractory insulation performance of the equipment compartment that needs insulation.
