Detailed Implementation

[0023] This utility model discloses a dual-gun power supply device for mining cars. The following description, in conjunction with a preferred embodiment (Embodiment 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0024] See attached diagram. Figures 1 to 8 , Figures 1 to 4 The dual-gun power supply device for the mine car is shown from different perspectives. Figures 5 to 8 The partial structure of the dual-gun power supply device for the mining car is shown.

[0025] Example 1.

[0026] Preferably, the dual-gun power supply device for the mine car includes a base 100 and a first charging gun assembly 200 and a second charging gun assembly 300 symmetrically disposed on both sides of the base 100. The structure of the first charging gun assembly 200 is the same as that of the second charging gun assembly 300, wherein:

[0027] The base 100 includes a support column 110 and two support column protrusions 120 located on both sides of the top of the support column 110. The support column protrusions 120 are integrally formed with the support column 110. The support column protrusions 120 are provided with a protrusion 121 and a lifting ring 122. One side of the protrusion 121 is fixedly connected to the support column protrusion 120, and the other end of the protrusion 121 is fixedly connected to the lifting ring 122 so that the first connecting line 210 (or the second connecting line 310) is internally connected to the protrusion ring 122.

[0028] The first charging gun assembly 200 includes a first connecting line 210, a first charging gun 220 and a first charging box 230. One end of the first connecting line 210 is connected to the first charging gun 220 and the other end of the first connecting line 210 is connected to the first charging box 230. The first charging gun 220 is plugged into the first charging box 230.

[0029] The second charging gun assembly 300 includes a second connecting line 310, a second charging gun 320, and a second charging box 330. One end of the second connecting line 310 is connected to the second charging gun 320, and the other end of the second connecting line 310 is connected to the second charging box 330. The second charging gun 320 is plugged into the second charging box 330.

[0030] This design ensures that either the first connecting line 210 or the second connecting line 310 passes through the convex ring 122, and that there is sufficient spacing between the lifting ring 122 and the first charging box 230 or the second charging box 330. If the mine car accidentally drives away before completing charging, the first connecting line 210 or the second connecting line 310 is most likely to break at the lifting ring 122, rather than being pulled directly out of the first charging box 230 or the second charging box 330, thereby reducing safety hazards and meeting the high protection level standards for mining sites.

[0031] The base 100 also includes two support column extensions 130 located on both sides of the top of the support column 110, and the support column extensions 130 are integrally formed with the support column 110.

[0032] The support column extension 130 incorporates an electrochromic layer 131. Under normal charging conditions, the electrochromic layer 131 maintains its default color because the induced voltage at both ends does not reach a threshold. When an abnormally high induced voltage occurs (e.g., the output voltage of the connecting line is higher than standard), the induced voltage at both ends of the electrochromic layer 131 reaches the threshold and begins to change color. By observing whether the electrochromic layer 131 at the top of the base 100 changes color, the user can help determine if there is an abnormal charging condition and take timely measures to avoid potential safety hazards.

[0033] The first charging gun 220 is provided with a first charging gun positioning rod 221, and the first charging box 230 is provided with a first charging box interface 231. The first charging gun positioning rod 221 abuts against the first charging box interface 231, so that the first charging gun 220 can be inserted into the first charging box 230.

[0034] The second charging gun 320 is provided with a second charging gun positioning rod (not shown in the figure), and the second charging box 330 is provided with a second charging box interface (not shown in the figure). The second charging gun positioning rod abuts against the second charging box interface, so that the second charging gun 320 can be inserted into the second charging box 330.

[0035] The base 100 is made of insulating material.

[0036] It is worth mentioning that the specific components and other technical features of the electrochromic layer 131 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0037] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
