Description

Technical Field

[0001] This utility model relates to the field of cable grounding system technology, and in particular to a base plate assembly and a cable grounding box having the base plate assembly. Background Technology

[0002] During the laying of high-voltage cables, grounding systems are installed at appropriate locations to conduct the induced voltage generated during cable operation to the ground, eliminating the adverse effects of overvoltage and overcurrent on cable line operation. The grounding system mainly consists of grounding boxes, grounding cables, return cables, etc.

[0003] Generally, the relevant cables pass through the bottom plate of the grounding box and enter the interior of the grounding box. In related technologies, through holes are made in the bottom plate for the cables to pass through, and then sealant is applied between the wall of the through hole and the cable to achieve a seal. However, different cables have different diameters. After smaller cables pass through the through hole, the gap between the cable and the wall of the through hole is larger, which requires more sealant and increases the cost. In addition, the larger gap between the cable and the wall of the through hole is not conducive to the adhesion of the sealant. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a base plate assembly that can be applied to cables of different sizes, saves on the use of sealant, and improves the adhesion of the sealant.

[0005] This utility model also proposes a cable grounding box having the above-mentioned base plate assembly.

Therefore, each cable pass coil is a removable structure. Depending on the cable diameter, the cable pass coil with the smaller inner diameter can be knocked off, allowing the cable to pass through the cable pass coil that matches the cable diameter. This satisfies the cable insertion requirement while ensuring that there is no large gap between the inner wall of the cable pass coil and the cable. This reduces the amount of sealant used, saves costs, improves the adhesion of the sealant, reduces the risk of sealant peeling off, and improves sealing performance.

[0010] According to some embodiments of the present invention, a plurality of connecting portions are provided between the cable coil with the largest inner diameter and the wall of the through hole, and arranged around the axis of the through hole.

[0011] According to some embodiments of the present invention, the thickness of the connecting portion is less than the thickness of the cable through coil, wherein the thickness directions of both the connecting portion and the cable through coil are parallel to the axial direction of the through hole.

[0012] According to some embodiments of the present invention, the base plate assembly includes an outer frame and a flap, the outer frame is provided with an opening, the flap is rotatably connected to the outer frame and can be lifted to cover the opening, and the through hole is formed in the flap.

[0013] According to some embodiments of the present invention, the flap includes a first flap and a second flap, one side of the first flap is rotatably connected to one side of the opening, and one side of the second flap is rotatably connected to the other side of the opening, and the first flap and the second flap are arranged side by side.

[0014] The through hole includes a first half-hole formed on the side of the first flap near the second flap, and a second half-hole formed on the side of the second flap near the first flap. Part of the structure of each cable through coil is disposed in the first half-hole, and other structures of each cable through coil are disposed in the second half-hole.

[0015] According to some embodiments of the present invention, the flap is configured to be able to flip upward relative to the outer frame and is restricted from flipping downward relative to the outer frame.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1 As shown, an embodiment of the present invention relates to a rainproof, highly sealed cable grounding box, which includes a box body 100 and electrical components (not shown) disposed inside the box body 100.

[0035] Combination Figure 1 and Figure 2 The box body 100 includes a side panel assembly 110, a door frame 120, a box door 130, a box cover 140, a storage shell 150, and a bottom plate assembly 160.

[0036] The side panel assembly 110 includes a rear side panel 111 and two side side panels 112. The rear ends of the two side side panels 112 are respectively connected to the two opposite ends of the rear side panel 111 in the horizontal direction, and the two side side panels 112 are spaced apart and arranged opposite each other.

[0037] The door frame 120 is connected to the front end of the two side panels 112. The door 130 is rotatably connected to the side panel assembly 110. When the door 130 is in the closed state, the door 130 covers the front side of the door frame 120.

[0038] The base plate assembly 160 is connected to the bottom of the side plate assembly 110.

[0039] like Figures 4 to 6 As shown, the base plate assembly 160 has through holes 1601 extending through the upper and lower sides of the base plate assembly 160, and a through structure 163 is provided within the through holes 1601. Further details can be found in [link to documentation]. Figure 6 The cable passage structure 163 includes multiple cable passage coils 1631. The inner diameters of the different cable passage coils 1631 are different. The multiple cable passage coils 1631 are coaxially arranged, and the cable passage coil 1631 with a larger inner diameter is arranged around the cable passage coil 1631 with a smaller inner diameter. A connecting part 1632 is provided between each two adjacent cable passage coils 1631, and between the cable passage coil 1631 with the largest inner diameter and the wall of the cable passage hole 1601.

[0040] It is understood that the multiple cable pass coils 1631 are concentric in structure, and all of the multiple cable pass coils 1631 are concentrically arranged with the through hole 1601. The cable pass coil 1631 can be a complete loop structure or a non-closed loop structure. Every two adjacent cable pass coils 1631 are connected by a connecting part 1632, and the cable pass coil 1631 with the largest inner diameter is connected to the wall of the through hole 1601 by the connecting part 1632.

[0041] In this embodiment, the connecting portion 1632 located between two adjacent cable loopers 1631 and the two cable loopers 1631 connected thereto are detachably connected. In other words, the connecting portion 1632 and the cable loopers 1631 connected thereto can be separated. Separation of the connecting portion 1632 and the cable loopers 1631 can be achieved by, but is not limited to, breaking the connection between the connecting portion 1632 and the cable loopers 1631. Of course, in other embodiments, one of the connecting portion 1632 located between two adjacent cable loopers 1631 and the two cable loopers 1631 connected thereto is detachably connected.

[0042] In addition, the connection portion 1632 between the cable coil 1631 with the largest inner diameter and the wall of the through hole 1601, and the cable coil 1631 and / or the wall of the through hole 1601 connected thereto are detachably connected.

[0043] In the base plate assembly 160 of this utility model, each cable pass coil 1631 is a removable structure. Depending on the cable diameter, the cable pass coil 1631 with a smaller inner diameter can be knocked off, allowing the cable to pass through the cable pass coil 1631 that matches the cable diameter. This satisfies the cable insertion requirement while ensuring that there is no large gap between the inner wall of the cable pass coil 1631 and the cable, thus reducing the amount of sealant used and saving costs.

[0044] Furthermore, a plurality of connecting portions 1632 are provided between each pair of adjacent cable pass coils 1631, arranged around the axis of the through hole 1601. This improves the reliability of the connection between each pair of adjacent cable pass coils 1631.

[0045] Similarly, a plurality of connecting portions 1632 are provided between the cable coil 1631 with the largest inner diameter and the wall of the through hole 1601, arranged around the axis of the through hole 1601. In this way, the reliability of the connection between the cable coil 1631 with the largest inner diameter and the wall of the through hole 1601 can be improved.

[0046] It should be noted that the thickness of the connecting portion 1632 is less than the thickness of the cable loop 1631, and the thickness directions of both the connecting portion 1632 and the cable loop 1631 are parallel to the axial direction of the through hole 1601. This allows the connecting portion 1632 to be knocked off relatively easily. The thickness of the connecting portion 1632 can be set between 1mm and 3mm.

[0047] The cable coil 1631, the connecting part 1632, and the wall of the through hole 1601 can be integrally formed.

[0048] It should be noted that, in order to accommodate more types of cables, the through hole 1601 does not have to be a regular circle; it can be other irregular structures.

[0049] like Figure 4 As shown, in some embodiments, the base plate assembly 160 is further provided with a closed groove 165, and the portion surrounded by the groove 165 is defined as a knockable cover 166. It is understood that the knockable cover 166 can be knocked down to form a cable pass-through opening on the base plate assembly 160, allowing other cables to pass through. Of course, when no additional cable is needed, the knockable cover 166 will not be knocked down, ensuring the sealing effect of the base plate assembly 160.

[0050] Combination Figure 4 and Figure 5 In some embodiments, the base plate assembly 160 includes an outer frame 161 and a flap 162. The outer frame 161 is provided with an opening. The flap 162 is rotatably connected to the outer frame 161 and can be lifted to cover the opening. A wire through hole 1601 is formed in the flap 162.

[0051] Understandably, the flap 162 is rotatably connected to the outer frame 161. The flap 162 is configured to be able to flip and adjust the angle. In this way, even if the cable passes through the base plate assembly 160 into the interior of the housing 100, the cable has greater freedom and can be easily inserted into different positions.

[0052] Specifically, the flap 162 includes a first flap 1621 and a second flap 1622. One side of the first flap 1621 is rotatably connected to one side of the opening, and one side of the second flap 1622 is rotatably connected to the other side of the opening. The first flap 1621 and the second flap 1622 are arranged side by side. The wire through hole 1601 includes a first half hole 1601a formed on the side of the first flap 1621 near the second flap 1622, and a second half hole 1601b formed on the side of the second flap 1622 near the first flap 1621. A portion of the structure of each cable coil 1631 is disposed in the first half hole 1601a, and the other portion of the structure of each cable coil 1631 is disposed in the second half hole 1601b.

[0053] It should be noted that the flap 162 is configured to flip upward relative to the outer frame 161 and is restricted from flipping downward relative to the outer frame 161. In this way, when the cable passes through the base plate assembly 160 into the housing 100, there is no need to worry about the flap 162 flipping downward and affecting the assembly.

[0054] Specifically, the first flap 1621 is rotatably connected to the outer frame 161 via the first hinge 1641. The first hinge 1641 is located on the upper side of the outer frame 161. One hinge of the first hinge 1641 is connected to the upper side of the outer frame 161, and the other hinge is connected to the upper side of the first flap 1621. When the first flap 1621 is in the closed state, the side wall of the first flap 1621 near its rotation axis is in contact with the side wall of the opening, and the side wall of the opening restricts the first flap 1621 from flipping downward.

[0055] Similarly, the second flap 1622 is rotatably connected to the outer frame 161 via the second hinge 1642. The second hinge 1642 is located on the upper side of the outer frame 161. One hinge of the second hinge 1642 is connected to the upper side of the outer frame 161, and the other hinge is connected to the upper side of the second flap 1622. When the second flap 1622 is in the closed state, the side wall of the second flap 1622 near its rotation axis is in contact with the side wall of the opening, and the side wall of the opening restricts the second flap 1622 from flipping downward.

[0056] like Figure 3 , Figure 4 As shown, in some embodiments, the upper surface of the base plate assembly 160 is provided with a raised protrusion 167 located on the rotation path of the door 130, and the raised protrusion 167 gradually increases in height along the closing direction of the door 130. In this way, during the closing process of the door 130, the door 130 is gradually pulled up, thereby making the door 130 more stable and reducing the risk of the door 130 shaking.

[0057] Specifically, the base plate assembly 160 is provided with two raised protrusions 167, which are arranged on the upper surface of the base plate assembly 160, one on the left and one on the right. This makes the left and right sides of the door 130 raised to a more consistent height.

[0058] like Figure 2 As shown, the storage shell 150 is provided on the side panel assembly 110 around its four sides, and the storage shell 150 covers the four sides of the side panel assembly 110. The lid 140 covers the four sides of the storage shell 150. When it rains, most of the rainwater can flow away along the lid 140, reducing the risk of entering the interior of the box 100.

[0059] In the cable grounding box of this utility model, the connecting part 1632 and the cable pass coil 1631 connected thereto can be separated. The connecting part 1632 between the cable pass coil 1631 with the largest inner diameter and the hole wall of the through hole 1601, and the cable pass coil 1631 connected thereto and the hole wall of the through hole 1601 are detachably connected. Therefore, each cable pass coil 1631 is a removable structure. Depending on the cable diameter, the cable pass coil 1631 with the smaller inner diameter can be knocked off, so that the cable can pass through the cable pass coil 1631 that matches the cable diameter. In this way, the cable insertion requirement is met, and at the same time, it can be ensured that there is no large gap between the inner wall of the cable pass coil 1631 and the cable. This can reduce the amount of sealant used, save costs, improve the adhesion of the sealant, reduce the risk of sealant falling off, and improve the sealing performance.
