Description

Technical Field

[0001] The utility model relates to the technical field of outdoor energy storage equipment, in particular to a wire passing structure for an outdoor integrated energy storage cabinet. Background Art

[0002] The outdoor integrated energy storage cabinet is a device used in industrial and commercial parks, groups and enterprises, shopping malls and office buildings, distributed photovoltaic, photovoltaic storage charging and testing power stations and other places. According to the different functions and models of the outdoor integrated energy storage cabinet, the outdoor integrated energy storage cabinet generally includes an electrical room and a battery room separated by a cabin partition. The electrical components in the electrical room and the battery room are electrically connected through wiring that passes through the cabin partition to achieve electrical conduction; during use, air convection often needs to be isolated between the electrical room and the battery room to prevent moisture in the electrical room from entering the battery room through the gaps in the cable holes, causing condensation on the battery and thus interfering with the normal operation of the battery. At present, the industry mainly achieves this by setting a cable connector 2 (such as Figure 1 As shown) or rubber protective ring 3 (as Figure 2 There are two ways to achieve the connection and fixation of the cable 4 on the cabin partition 1 (as shown). The former requires that rotation space for the cable connector 2 be reserved. The cable connector 2 occupies a large space, making it impossible to arrange the cable 4 compactly. In addition, the size of the terminal block 5 at the end of the cable is much larger than the cable diameter. If the terminal block 5 passes through the cable connector 2 normally, the connection between the cable 4 and the cable connector 2 will not be tightly pre-tightened, making it difficult to isolate the space convection. Furthermore, due to the limitation of the spacing between the cables, the installation of the cable connector 2 is difficult. It is also difficult to find a cable connector 2 of suitable size according to the cable diameter, which increases the difficulty of installing the cable 4. The latter requires cutting the center position of the rubber protective ring 3 when threading the wire, which will result in the middle part of the rubber protective ring 3 after threading the wire unable to be tightly pre-tightened, making it difficult to achieve the purpose of isolating air convection. In addition, when threading the wire with the rubber protective ring 3, it is easy to pull off the rubber protective ring 3 due to the influence of the pulling wire and the bending of the cable, thereby affecting the airflow isolation effect of the cabinet.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Please combine Figure 3-4 as well as Figure 6-7 The utility model discloses a wire-passing structure for an outdoor integrated energy storage cabinet with good airflow isolation effect and easy installation. The wire-passing structure is used to be installed on the cabin partition 1 of the outdoor integrated energy storage cabinet and corresponds to the wire-passing hole of the cabin partition 1, so as to provide a fixing part for the cable 4 passing through the wire-passing hole, and at the same time seal the wire-passing part to prevent the air in the two side cabins separated by the cabin partition 1 from generating convection at the wire-passing hole, thereby avoiding condensation on the battery. Specifically, the wire-passing structure of this embodiment includes a connecting pressure plate 100 and a flexible wire-passing plate 200. The connecting pressure plate 100 includes a first surface fixedly connected to the cabin partition 1 and a second surface facing away from the cabin partition 1. A mounting groove 110 is provided on the first surface, and a first through hole 120 is provided on the bottom surface of the mounting groove 110, which passes through the second surface and is connected to the wire-passing hole. The width or aperture of the first through hole 120 is smaller than the width or inner diameter of the mounting groove 110, so that the bottom surface of the mounting groove 110 forms a limiting step 130 at the edge of the first through hole 120. The flexible wire-passing plate 200 is embedded in the mounting groove 110 and abuts against the inner wall of the mounting groove 110 and the limiting step 130 respectively. In other words, by providing the mounting groove 110 and the first through hole 120 on the connecting pressure plate 100, the flexible wire-passing plate 200 can be limited to prevent the flexible wire-passing plate 200 from falling off the connecting pressure plate 100 when driven by the cable 4. The width or diameter of the flexible threading plate 200 is greater than the width or inner diameter of the threading hole, and the thickness of the flexible threading plate 200 is greater than the depth of the mounting groove 110. In this way, when the first surface of the threading pressure plate 100 is in contact with the cabin partition 1, the flexible threading plate 200 is deformed under the joint extrusion of the threading pressure plate 100 and the cabin partition 1. At the same time, the flexible threading plate 200 abuts against the edge of the threading hole to prevent the air between adjacent cabins from flowing through the edge of the threading hole and further through the mating part of the threading pressure plate 100 and the cabin partition 1, thereby preventing air convection between adjacent cabins.

[0023] The flexible threading plate 200 is provided with a plurality of second through holes 210 that are connected to the first through hole 120 and the threading hole and are used to thread the cable 4. The aperture of the second through hole 210 is smaller than the diameter of the cable 4. In this embodiment, the flexible threading plate 200 is deformed when subjected to external forces (such as the pulling force of the cable 4 and the squeezing force of the cabin partition 1 and the threading pressure plate 100). Thus, when the cable 4 and the terminal 5 at the end of the cable 4 are inserted into the second through hole 210, the flexible threading plate 200 is squeezed by the cable 4 and the terminal 5, causing the second through hole 210 to deform, thereby expanding the second through hole 210 so that the terminal 5 and the cable 4 can pass through the second through hole 210 smoothly. Finally, the inner wall of the second through hole 210 partially restores the elastic deformation and presses the outer surface of the cable 4 to prevent air between adjacent compartments from flowing through the connection between the cable 4 and the flexible threading plate 200. In addition, a notch is provided on the side surface of the ring of the flexible threading plate that is connected to the second through hole. In this way, when the second through hole 210 is squeezed by the terminal 5, the gap provides conditions for the second through hole to become larger, reducing the difficulty of threading and fixing the cable and the terminal. In this embodiment, the flexible threading plate 200 is made of silicone or rubber material. In other embodiments, the flexible threading plate 200 can also be made of other common materials on the market that can produce plastic deformation, such as TPU (thermoplastic polyurethane) or EVA (ethylene-vinyl acetate copolymer) material. In addition, in one embodiment, a plurality of second through holes 210 are arranged in an array on the flexible threading plate 200, for example, a plurality of second through holes 210 are arranged in a square array on the flexible threading plate 200, or a plurality of second through holes 210 are arranged in a circular array on the flexible threading plate 200. Preferably, in this embodiment, the flexible threading plate 200 is provided with 2x3, i.e., 2 rows and 3 columns, a total of 6 second through holes 210.

[0024] It should be noted that the through-type pressure plate 100 of this solution mainly includes two forms. In one embodiment, a mounting groove 110 (such as Figure 5 As shown), in this structure, the thickness of the area outside the slot of the mounting groove 110 on the through-connecting pressure plate 100 is greater than the wall thickness of the area where the mounting groove 110 is located on the through-connecting pressure plate 100. The mounting groove 110 can be obtained by milling on the plate-shaped through-connecting pressure plate 100, or the through-connecting pressure plate 100 having the mounting groove 110 and the second through hole 210 can be obtained by punching. In another embodiment, the middle portion of the through-connecting pressure plate 100 is raised in the direction away from the cabin partition to form the mounting groove 110. Specifically, in this embodiment, a plate body of equal thickness is bent, deformed, and opened to obtain a through-connecting pressure plate 100 with equal thickness at all locations and having the mounting groove 110 and the second through hole 210 (as shown in FIG. Figure 6 As shown), the structure can also be obtained by forming a punch and opening a hole.

[0025] In one embodiment, the first through hole 120 is a square hole, a round hole, a waist hole or a polygonal hole with more than four sides. Preferably, in this embodiment, the first through hole 120 is a square hole, the second through hole 210 is a round hole, and the outer contour shape of the flexible threading plate 200 is adapted to the inner contour shape of the mounting groove 110 to prevent the flexible threading plate 200 from loosening in the mounting groove 110. The through-hole pressure plate 100 is screwed to the cabin partition 1, or the through-hole pressure plate 100 is welded to the cabin partition 1. Preferably, the through-hole pressure plate 100 is fixedly connected to the cabin partition 1 by a screw 140 provided at the edge of the notch of the mounting groove 110, and a waterproof nut is provided at the locking portion between the screw 140 and the cabin partition 1 to prevent the screw 140 from falling off from the cabin partition 1.

[0026] In one embodiment, the wire-passing structure further includes a pressure plate sealing ring 300, which is respectively attached to the first surface of the through-pressure plate 100 and the cabin partition 1 and surrounds the wire-passing hole of the cabin partition 1. By providing the pressure plate sealing ring 300, the gap at the connection portion between the through-pressure plate 100 and the cabin partition 1 can be sealed to prevent air from flowing in the gap at the connection portion between the through-pressure plate 100 and the cabin partition 1, thereby reducing air convection. Preferably, the pressure plate sealing ring 300 is made of silicone, rubber or TPU material. In addition, in this embodiment, the first surface of the through-pressure plate 100 is provided with an annular limiting groove 150 at the edge of the notch of the mounting groove 110, and the pressure plate sealing ring 300 is embedded in the annular limiting groove 150. The depth of the annular limiting groove 150 is less than the thickness of the pressure plate sealing ring 300, and the inner ring width or diameter of the annular limiting groove 150 is greater than the width or inner diameter of the wire-passing hole. By providing an annular limiting groove 150 on the first surface, the pressure plate sealing ring 300 can be limited in position, thereby avoiding the problem of insufficient sealing between the wire-passing structure and the cabin bulkhead 1 due to displacement of the pressure plate sealing ring 300 during installation of the wire-passing structure. By making the depth of the annular limiting groove 150 less than the thickness of the pressure plate sealing ring 300 and the inner ring width or diameter of the annular limiting groove 150 greater than the width or inner diameter of the threading hole, while ensuring that the pressure plate sealing ring 300 corresponds to the edge of the threading hole, the pressure plate sealing ring 300 is deformed by the combined extrusion of the cabin bulkhead 1 and the through-connecting pressure plate 100, thereby fully sealing the gap at the connection between the through-connecting pressure plate 100 and the cabin bulkhead 1. Furthermore, the pressure plate sealing ring 300 has a square ring structure, a circular ring structure, or a ring-shaped runway structure, and the inner contour of the annular limiting groove 150 is adapted to the outer contour of the pressure plate sealing ring 300. Preferably, the pressure plate sealing ring 300 is a square ring structure, and the annular limiting groove 150 is a square ring groove.

[0027] The above-mentioned wire-passing structure for the outdoor integrated cabinet for energy storage, by setting the connecting pressure plate 100 and the flexible wire-passing plate 200, when the cable 4 is installed, it is only necessary to embed the flexible wire-passing plate 200 into the installation groove 110 of the connecting pressure plate 100, align the connecting pressure plate 100 with the wire-passing hole and fix it on the cabin partition 1, and then use the deformable feature of the flexible wire-passing plate 200 to pass the cable 4 through the second through hole 210 of the flexible wire-passing plate 200 one by one, thereby realizing the installation of the cable 4 and reducing the cost. The difficulty of installing the cable 4 and the wire-passing structure is reduced, and the cable 4 is pressed by the inner surface of the second through hole 210 after passing through the second through hole 210. At the same time, the flexible wire-passing plate 200 is deformed under the joint extrusion of the cabin partition 1 and the through-hole pressure plate 100 to seal the gap between the edge of the wire-passing hole and the through-hole pressure plate 100, thereby achieving sealing of the wire-passing hole on the cabin partition 1 to avoid convection of air on both sides of the cabin partition 1 through the wire-passing hole, thereby improving the airflow isolation effect of the cabinet.

[0028] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
