The terminology used in the description of the present disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0037] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0038] Please refer to Figure 1The static grounding box structure of the embodiment comprises a metal box 100 and a static grounding assembly; the metal box 100 is fixedly installed on the refueling island 10; an installation cavity 110 is formed in the metal box 100, and the installation cavity 110 is used for installing a refueling pump (not shown in the figure); the static grounding assembly is located in the installation cavity 110; the static grounding assembly comprises a plurality of wires 210, a plurality of conductive bolt connection assemblies 220, a grounding conductive pile 230, and a wire distribution conductive row 240; the grounding conductive pile 230 is vertically installed at the central position of the bottom of the metal box 100; the grounding conductive pile 230 is used for penetrating through the refueling island 10 and is conductively connected to the ground; the wire distribution conductive row 240 is transversely installed on the grounding conductive pile 230 and is conductively connected to the grounding conductive pile 230; the wire distribution conductive row 240 is spaced apart along the length direction and is provided with a plurality of connection positions; the plurality of conductive bolt connection assemblies 220 are fixedly installed on the inner circumferential wall of the metal box 100; and one conductive bolt connection assembly 220 is conductively connected to one connection position through one wire 210.

[0039] It can be understood that, since the grounding conductive pile 230 is vertically installed at the central position of the bottom of the metal box 100 and the plurality of conductive bolt connection assemblies 220 are fixedly installed on the inner circumferential wall of the metal box 100, the plurality of conductive bolt connection assemblies 220 can be transversely installed around the wire distribution conductive row 240 transversely installed on the grounding conductive pile 230; since the wire distribution conductive row 240 is spaced apart along the length direction and is provided with a plurality of connection positions, one conductive bolt connection assembly 220 is conductively connected to one connection position through one wire 210, so that the plurality of wires 210 are dispersed like rays, thereby making the wires 210 less likely to be entangled together, and reducing the occurrence of connection disorder.

[0040] It can be understood that, since the static grounding assembly is located in the installation cavity 110, that is, the wires 210 are kept in the installation cavity 110, the influence of external factors such as rain, frost and snow on the wires 210 is reduced. In addition, by penetrating the grounding conductive pile 230 through the refueling island 10, the wire distribution conductive row 240 is transversely installed on the grounding conductive pile 230, and after one conductive bolt connection assembly 220 is conductively connected to one connection position through one wire 210, the electric charge on the metal box 100 can be guided to the wire distribution conductive row 240 through the conductive bolt connection assemblies 220, and the wire distribution conductive row 240 can conduct static electricity to the ground through the wire distribution conductive row 240, thereby quickly releasing the static electricity on the refueling machine and improving the use safety of the refueling machine.

[0041] Please refer to Figure 2In some embodiments, the conductive bolt assembly 220 includes a fixing bolt 2210 and a locking nut 2220. The fixing bolt 2210 is welded to the inner wall of the metal cabinet 100, and the locking nut 2220 is threadedly locked with the fixing bolt 2210. The first end of the wire 210 is arranged between the locking nut 2220 and the fixing bolt 2210. It can be understood that, since the locking nut 2220 is threadedly locked with the fixing bolt 2210, and the first end of the wire 210 is arranged between the locking nut 2220 and the fixing bolt 2210, the connection strength between the conductive bolt assembly 220 and the first end of the wire 210 can be flexibly adjusted by screwing the locking nut 2220.

[0042] Referring to Figure 2 In some embodiments, the first end of the wire 210 is welded with a first conductive sleeve 2110. The fixing bolt 2210 passes through the first conductive sleeve 2110 and is threadedly locked with the locking nut 2220. It can be understood that, since the first conductive sleeve 2110 is welded on the first end of the wire 210, by making the fixing bolt 2210 pass through the first conductive sleeve 2110 and then threadedly locked with the locking nut 2220, the first conductive sleeve 2110 can be firmly installed on the fixing bolt 2210, thereby forming a stable electrical connection structure.

[0043] Referring to Figure 3 In some embodiments, the grounding conductive pile 230 includes an intermediate support 2310 and two side supports 2320. Each side support 2320 is welded with the intermediate support 2310, and the two side supports 2320 are symmetrically arranged. An electric wire tapping conductive row 240 is arranged at the end of the intermediate support 2310 and at the end of each side support 2320. It can be understood that, since each side support 2320 is welded with the intermediate support 2310, the intermediate support 2310 and each side support 2320 can form a close connection structure. Then, by arranging an electric wire tapping conductive row 240 at the end of the intermediate support 2310 and at the end of each side support 2320, the number of conductive positions can be increased, and the wire 210 can be more dispersedly arranged.

[0044] Referring to Figure 1 With Figure 3 In some embodiments, the arrangement direction of the electric wire tapping conductive rows 240 is consistent with the length direction of the metal cabinet 100. It can be understood that, since the arrangement direction of the electric wire tapping conductive rows 240 is consistent with the length direction of the metal cabinet 100, i.e., the plurality of electric wire tapping conductive rows 240 are arranged along the length direction of the metal cabinet 100, the electric wire tapping conductive rows 240 can be more evenly dispersed in the installation cavity 110, i.e., the positions of the conductive positions can be more dispersed.

[0045] Referring toFigure 3 In some embodiments, the end of the side bracket 2320 is in abutting arrangement with a portion of the corresponding line tapping conductive strip 240, and the side bracket 2320 and the corresponding line tapping conductive strip 240 are locked by the locking assembly 2330. It can be understood that, by arranging the end of the side bracket 2320 in abutting arrangement with a portion of the corresponding line tapping conductive strip 240, after the side bracket 2320 and the corresponding line tapping conductive strip 240 are locked by the locking assembly 2330, the side bracket 2320 and the corresponding line tapping conductive strip 240 can be in close contact with each other to form a tightly connected structure.

[0046] Referring to Figure 3 In some embodiments, the locking assembly 2330 includes a first locking bolt 2331 and a first nut 2332; the first locking bolt 2331 sequentially penetrates the side bracket 2320 and the corresponding line tapping conductive strip 240, and is threadedly locked to the first nut 2332. It can be understood that, since the first locking bolt 2331 sequentially penetrates the side bracket 2320 and the corresponding line tapping conductive strip 240, and is then threadedly locked to the first nut 2332, the connection strength between the side bracket 2320 and the corresponding line tapping conductive strip 240 can be flexibly adjusted by screwing the first nut 2332.

[0047] Referring to Figure 1 With Figure 3 In some embodiments, a second conductive sleeve ring 2120 is welded on the second end of the wire 210; the second conductive sleeve ring 2120 is located between the side bracket 2320 and the corresponding line tapping conductive strip 240, and is sleeved on the first locking bolt 2331. It can be understood that, by sleeving the second conductive sleeve ring 2120 located between the side bracket 2320 and the corresponding line tapping conductive strip 240 on the first locking bolt 2331, a tightly connected structure can be formed between the second conductive sleeve ring 2120 and the first locking bolt 2331 by screwing the first nut 2332.

[0048] In some embodiments, the first conductive sleeve ring 2110 and / or the second conductive sleeve ring 2120 is a galvanized sleeve ring. Specifically, the first conductive sleeve ring 2110 is a galvanized sleeve ring, or the second conductive sleeve ring 2120 is a galvanized sleeve ring, or both the first conductive sleeve ring 2110 and the second conductive sleeve ring 2120 are galvanized sleeve rings. Among them, the galvanized sleeve ring has stronger corrosion resistance, which can improve the conduction stability of the wire 210.

[0049] Referring to Figure 1In some embodiments, the metal cabinet 100 is provided with an electrostatic discharger 300 on the outer side wall thereof, which is close to the position on the metal cabinet 100 for mounting the refueling gun 400. It can be understood that, since the electrostatic discharger 300 is close to the position on the metal cabinet 100 for mounting the refueling gun 400, the refueling operator can more conveniently contact the electrostatic discharger 300 to release the electric charge on the refueling operator before refueling, so that the refueling operator is safer when operating the refueling gun 400.

[0050] Please refer to Figures 1 to 3 The present disclosure also provides a refueling machine, which comprises a refueling gun 400, a refueling pump (not shown in the figure) and the electrostatic grounding cabinet structure of any of the above embodiments; the refueling pump is installed in the mounting cavity 110, the oil outlet end of the refueling pump is communicated with the refueling gun 400, and the oil inlet end of the refueling pump is used to be communicated with the underground oil tank (not shown in the figure). It can be understood that, by applying the electrostatic grounding cabinet structure of the present disclosure to the refueling machine, since the electrostatic grounding assembly is located in the mounting cavity 110, i.e. the wires 210 are kept in the mounting cavity 110, the influence of external factors such as rain, snow and the like on the wires 210 is reduced. In addition, by making the grounding conductive pile 230 penetrate the refueling island 10, the wire distribution conductive row 240 is transversely installed on the grounding conductive pile 230, after being electrically connected by a wire 210 between one wire distribution position and one conductive bolt connection assembly 220 close to each other, the electric charge on the metal cabinet 100 can be guided to the wire distribution conductive row 240 through each conductive bolt connection assembly 220, and the wire distribution conductive row 240 then conducts the static electricity to the ground through the wire distribution conductive row 240, thereby quickly releasing the static electricity on the refueling machine to improve the use safety of the refueling machine.

[0051] Compared with the prior art, the present disclosure has at least the following advantages:

[0052] 1) Since the grounding conductive pile 230 is vertically installed at the central position of the bottom of the metal cabinet 100, and the plurality of conductive bolt connection assemblies 220 are fixedly arranged on the inner circumferential wall of the metal cabinet 100, the plurality of conductive bolt connection assemblies 220 can be transversely installed around the wire distribution conductive row 240 on the grounding conductive pile 230. Since the wire distribution conductive row 240 is spaced apart in the length direction, when one wire distribution position and one conductive bolt connection assembly 220 close to each other are electrically connected by a wire 210, the plurality of wires 210 are dispersed like rays, so that the wires 210 are less likely to be entangled together, thereby reducing the occurrence of wiring disorder.

[0053] 2) Since the grounding assembly is located in the installation cavity 110, that is, the wire 210 is kept in the installation cavity 110, the influence of external factors such as rain, frost and snow on the wire 210 is reduced. In addition, by making the grounding conductive pile 230 penetrate through the refueling island 10, the wire distribution conductive row 240 is transversely installed on the grounding conductive pile 230, after being conductively connected by a wire 210 between a conductive connection site and a conductive bolt connection assembly 220 close to each other, the charge on the metal case 100 can be guided to the wire distribution conductive row 240 through each conductive bolt connection assembly 220, and the wire distribution conductive row 240 then conducts the static electricity to the ground through the wire distribution conductive row 240, thereby quickly releasing the static electricity on the refueling machine to improve the use safety of the refueling machine.

[0054] The above-described embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for those skilled in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
