Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a protective structure for the bottom wiring hole of a charging pile. Background Technology

[0002] A charging pile is a power replenishment device for electric vehicles, typically fixed to the ground. The wiring hole for a charging pile is usually located at the bottom of its side wall. This wiring hole (a 200*100mm oblong hole) generally requires five independent 95 square millimeter wires (approximately 14-18mm in diameter). To prevent the cables from being cut by the charging pile plate and to prevent moisture from entering the charging pile and condensation due to high ground humidity, the wiring hole needs to be properly sealed after wiring.

[0003] The current practice is to spray expanding foam to cure and complete the sealing operation. However, this method has the following drawbacks: 1. The curing time of expanding foam is long, and if the cable shakes during the curing period, it may cause the sealing to fail; 2. Subsequent maintenance requires a long time to clean and re-spray expanding foam for sealing.

[0004] To address this, we designed a protective structure for the wiring holes at the bottom of the charging pile. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a protective structure for the bottom wiring hole of a charging pile.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective structure for the bottom cable threading holes of a charging pile includes a waist-shaped thick plate, wherein the waist-shaped thick plate has a plurality of cable threading holes spaced apart along its long axis for cable threading; and a flange plate is provided at one end of the waist-shaped thick plate.

[0008] Each of the threading holes is provided with a sealing sleeve fitted onto the cable to seal the gap between the cable and the threading hole.

[0009] The waist-shaped thick plate is composed of two half-waist-shaped thick plates spliced ​​together. Each half-waist-shaped thick plate has multiple semi-circular holes along its length on the splicing surface. When two half-waist-shaped thick plates are spliced ​​together, the corresponding semi-circular holes are joined together to form the threading hole.

[0010] The flange plate is composed of two flange halves spliced ​​together. The flange halves are integrally formed with the corresponding half-waist thick plate, and the two ends of the two flange halves in the same direction are fixedly connected by a bolt and nut assembly.

[0011] Furthermore, the sealing sleeve is composed of two symmetrical sealing half-sleeves spliced ​​together, with each sealing half-sleeve embedded in the semi-circular hole of the corresponding half-waist-shaped thick plate.

[0012] Furthermore, the splicing surface area of ​​the semi-waist-shaped thick plate is also provided with a sealing sheet.

[0013] Furthermore, the sealing sheet corresponding to the same half-waist-shaped thick plate is integrally formed with the sealing half-body.

[0014] Furthermore, the splicing surface of the semi-waist-shaped thick plate has a raised ridge in the planar area, and the sealing sheet has a groove that matches the raised ridge, with the groove fitting onto the raised ridge.

[0015] Furthermore, a sealing ring is provided on the inner surface of the flange plate.

[0016] Furthermore, the sealing ring has a beveled opening.

[0017] Furthermore, the opening is staggered from the joint of the two semi-waist-shaped thick plates.

[0018] Furthermore, the inner surface of the flange plate is provided with an fitting groove for fixing the sealing ring.

[0019] Furthermore, the flange plate is provided with a number of mounting holes spaced apart along its circumference for fixing to the side wall of the charging pile by self-tapping screws.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. It adopts a split waist-shaped thick plate, flange plate and sealing sleeve, and is quickly assembled by bolt and nut group. Compared with the existing technology, there is no need to wait for the foam to cure. This not only shortens the installation time, but also effectively ensures the sealing of the wire hole, and can also adapt well to the situation where the cable has been connected.

[0022] 2. The nested structure of protruding ridges and grooves blocks the water seepage path at the splice seam; and the sealing sheet and sealing half-body are integrally formed to eliminate the dead corners of leakage between cable holes and splice surfaces.

[0023] 3. The sealing sheet and the sealing half-sleeve are integrally molded, and the nested structure of convex ridges and grooves also improves the installation efficiency and overall consistency of the sealing sleeve. Attached Figure Description

[0030] Example 1, in conjunction with Appendix Figure 1-4 A protective structure for the bottom wiring hole of a charging pile, comprising:

[0031] Waist-shaped thick plate 1: It is composed of two symmetrical semi-waist-shaped thick plates 101 spliced ​​together. Each semi-waist-shaped thick plate 101 has multiple semi-circular holes 102 along the length direction on the splicing surface. When two semi-waist-shaped thick plates 101 are spliced ​​together, the corresponding semi-circular holes 102 are combined to form multiple wire-passing holes 11, which are used to pass through multiple independent cables (such as 95 square wire).

[0032] In one example, there are five threading holes 11.

[0033] Specifically, the diameter of the wire-passing hole 11 is larger than the diameter of the cable. Due to the uncertainty of the cable diameter (depending on the brand and standard), the diameter of the wire-passing hole 11 needs to be larger than the maximum diameter of the cable. Preferably, the diameter of the wire-passing hole 11 is designed to be 20±0.5mm.

[0034] As needed, for convenient installation of the waist-shaped thick plate 1, the size of the waist-shaped thick plate 1 is smaller than the size of the wire hole. Preferably, the size of the waist-shaped thick plate 1 is 195*95mm.

[0035] Flange plate 2: It is composed of two flange halves 201 spliced ​​together. The flange halves 201 are integrally formed with the corresponding semi-waist-shaped thick plate 101. The two ends of the two flange halves 201 in the same direction are fixedly connected together by bolt and nut assembly 6.

[0036] Depending on the requirements, the waist-shaped thick plate 1 and the flange plate 2 can be made of metal or plastic.

[0037] Sealing sleeve 3: Located inside the cavity of each wire-passing circular hole 11, it is composed of two symmetrical sealing half-sleeves 301 spliced ​​together. Each sealing half-sleeve 301 is embedded in the semi-circular hole 102 of the corresponding semi-waist-shaped thick plate 101 to seal the gap between the cable and the wire-passing circular hole 11.

[0038] Sealing plate 4: Located on the joint surface of the semi-waist-shaped thick plate 101, and integrally formed with the sealing half-sleeve 301 of the same semi-waist-shaped thick plate 101. The joint surface of the semi-waist-shaped thick plate 101 is provided with a protruding ridge 103, and the sealing plate 4 is provided with a matching groove 41. The groove 41 is fitted onto the protruding ridge 103 to enhance the sealing performance of the joint surface.

[0039] Sealing ring 5: Located on the inner surface of flange plate 2 and fixed by fitting groove 21. Sealing ring 5 has a beveled opening 51, and the opening 51 is staggered from the joint of the two semi-waist-shaped thick plates 101 to prevent moisture from seeping in.

[0040] Installation structure: The flange plate 2 has multiple mounting holes 22 spaced apart along the circumference, and is fixed to the side wall of the charging pile by self-tapping screws.

[0041] Assembly steps:

[0042] 1. The sealing half-sleeve 301 is pre-embedded into the semi-circular hole 102 of the semi-waist-shaped thick plate 101, so that the protrusion 103 fits into the groove 41;

[0043] 2. Place the cables into the semicircular holes 102 of the two semi-circular thick plates 101 respectively;

[0044] 3. Align the two semi-waist-shaped thick plates 101, and press the sealing sheet 4 firmly against the splicing surface;

[0045] 4. Tighten the two flange halves 201 with bolt and nut assembly 6 to complete the splicing and fixing of waist-shaped thick plate 1 and flange plate 2;

[0046] 5. Embed the sealing ring 5 into the fitting groove 21 of the flange plate 2;

[0047] 6. Secure the flange plate 2 to the outside of the wiring hole at the bottom of the charging pile side wall by passing the self-tapping screw through the mounting hole 22.

[0048] Example 2: A protective structure for the bottom wiring hole of a charging pile, which differs from Example 1 in that: the sealing ring 5 is formed by a C-shaped sealing strip (with a C-shaped cross section) surrounding the wiring hole at the bottom of the side wall of the charging pile, that is, the C-shaped sealing strip is engaged with the outside of the wiring hole at the bottom of the side wall of the charging pile.

[0049] In this embodiment, the inner plate surface of the flange plate 2 is not provided with a fitting groove 21.

[0050] In this example, the dimensions of the waist-shaped thick plate 1 should be smaller than those in Embodiment 1, preferably 190*90mm.
