Description

Technical Field

[0001] The present invention relates to the technical field of circuit safety, and particularly to an anti-backfeeding power supply device. Background Art

[0002] At present, when the power grid is under maintenance, the general approach is to shut down the power supply system in the section where the maintenance line is located, and then maintenance personnel perform maintenance at high altitude. Using this method cannot guarantee the safety of maintenance personnel during maintenance because shopping malls, schools, and government agencies generally have their own power generation equipment, which will generate electricity during power outages, and there is a possibility of backfeeding into the power grid during the power generation process, making the maintenance line live and posing a safety hazard to maintenance personnel.

[0003] The existing methods to solve the above problems generally involve directly hanging a grounding wire on the maintenance section of the wire to avoid the maintenance area being energized due to power backfeeding. However, this method is very troublesome to operate, and since the wire is not completely parallel to the ground, it is sometimes inclined or sometimes bent downward in a certain arc, which is not conducive to hanging the grounding wire in such cases. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an anti-backfeeding power supply device that can facilitate the hanging of the grounding wire.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] An anti-backfeeding power supply device includes:

[0007] A wiring component, the wiring component includes a wiring main body, a pressing block, and a driving screw; a sliding groove and a pressing hole that communicate with each other are formed on the wiring main body, the pressing block is slidably fitted in the sliding groove, the driving screw is adapted to drive the pressing block to move towards the pressing hole, and a notch communicating with the pressing hole is further formed on the wiring main body;

[0008] A grounding component, the grounding component includes a connecting plate, an intermediate connecting member, and a grounding ring. The first end of the connecting plate is fixedly connected to the wiring main body, the second end of the connecting plate is hinged to the intermediate connecting member through a first hinge shaft, the grounding ring is hinged to the intermediate connecting member through a second hinge shaft, the first hinge shaft is perpendicular to the axis of the pressing hole, and the second hinge shaft is perpendicular to the first hinge shaft.

[0009] Further, the number of the connecting plates is two, the two connecting plates are arranged at intervals, the intermediate connecting member is located between the two connecting plates, and the first hinge shaft sequentially passes through one connecting plate, the intermediate connecting member, and the other connecting plate.

[0010] Further, two lugs are provided on the grounding ring, the intermediate connecting member is located between the two lugs, and the second hinge shaft is adapted to sequentially pass through one lug, the intermediate connecting member, and the other lug.

[0011] Further, a receiving hole is also formed in the wiring body, the receiving hole is located on one side of the sliding groove, and a reverse stop block and an elastic member are arranged in the receiving hole. The elastic member is adapted to abut the reverse stop block against the pressing block to prevent the pressing block from moving away from the pressing hole.

[0012] Further, a support surrounding frame is arranged on the wiring body, and the support surrounding frame is used to limit the movement of the pressing block in the depth direction of the sliding groove.

[0013] Further, a first anti-slip pattern is arranged in the pressing hole.

[0014] Further, one end of the pressing block facing the pressing hole is in a concave arc shape, and a second anti-slip pattern is arranged at one end of the pressing block facing the pressing hole.

[0015] Further, a first detachable insulating housing is arranged on the wiring assembly.

[0016] Further, a second detachable insulating housing is arranged on the grounding assembly.

The fixed housing surrounds the top edge and two side edges of the grounding ring. The detachable housing includes a first semi-tubular housing and a second semi-tubular housing. The first end of the first semi-tubular housing is hinged to the fixed housing, and the first end of the second semi-tubular housing is hinged to the fixed housing. The first ends of the first semi-tubular housing and the second semi-tubular housing face the same direction. The first semi-tubular housing and the second semi-tubular housing are respectively arranged on both sides of the bottom edge of the grounding ring, and the first semi-tubular housing and the second semi-tubular housing can be mutually clamped. Handles are arranged on both the first semi-tubular housing and the second semi-tubular housing.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: If there is an inclination angle between the wire and the ground, the intermediate connecting member and the grounding ring can rotate integrally around the first hinge shaft through the first hinge shaft, and finally the grounding ring is vertically oriented towards the ground, so as to facilitate the worker to hang the grounding wire. The above process assumes that the planes where the wiring assembly and the connecting plate are located are both vertical planes. If the planes where the wiring assembly and the connecting plate are located are inclined planes (intersecting with the vertical plane), at this time, the second hinge shaft can be used to make the plane where the grounding ring is located a vertical plane, so as to facilitate the hanging of the grounding wire.

Detailed implementation manners

[0028] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] As Figure 2-5 shown, a reverse power supply prevention device provided by an embodiment of the present invention is shown, which can also be called a grounding wire clamp, a line protection wire clamp, or an insulating wire grounding ring. It includes a wiring assembly and a grounding assembly. The wiring assembly includes a wiring body 11, a pressing block 12, and a driving screw 13; a sliding groove 111 and a pressing hole 112 that communicate with each other are formed in the wiring body 11, the pressing block 12 is slidably fitted in the sliding groove 111, the driving screw 13 is adapted to drive the pressing block 12 to move towards the pressing hole 112, and a notch 113 that communicates with the pressing hole 112 is also formed in the wiring body 11. The grounding assembly includes a connecting plate 21, an intermediate connecting member 22, and a grounding ring 23. The first end of the connecting plate 21 is fixedly connected to the wiring body 11, the second end of the connecting plate 21 is hinged to the intermediate connecting member 22 through a first hinge shaft 31, the grounding ring 23 is hinged to the intermediate connecting member 22 through a second hinge shaft 32, the first hinge shaft 31 is perpendicular to the axis of the pressing hole 112, and the second hinge shaft 32 is perpendicular to the first hinge shaft 31. It should be noted that the above-mentioned perpendicular refers to a skew perpendicular relationship.

[0032] During use, the wiring assembly is connected to the wire 41 of the maintenance section, and the grounding wire is hung on the grounding assembly. Specifically as follows: through the notch 113 on the wiring body 11, the wire 41 enters the pressing hole 112 on the wiring body 11, and then the driving screw 13 is used to drive the pressing block 12 to move towards the pressing hole 112, so as to fixedly connect the wiring assembly to the wire 41. Then the grounding wire is hung on the grounding ring 23, thereby completing the grounding of the wire 41 in the maintenance section and avoiding the reverse power supply from injuring people.

[0033] During the above-mentioned use process, with reference to Figure 8, if the wire 41 has an inclination angle with the ground, after the wiring assembly is installed, it will also be in an inclined state under the influence of the inclined wire 41. Since the first hinge axis 31 is perpendicular to the axis of the wire pressing hole 112, the intermediate connecting member 22 and the grounding ring 23 can rotate integrally around the first hinge axis 31, and finally the grounding ring 23 is vertically oriented towards the ground, thus facilitating the worker to connect the grounding wire. The above process assumes that the planes where the wiring assembly and the connecting plate 21 are located are both vertical planes. If the planes where the wiring assembly and the connecting plate 21 are located are inclined planes (intersecting with the vertical plane), at this time, after the intermediate connecting member 22 and the grounding ring 23 rotate integrally around the first hinge axis 31, the plane where the grounding ring 23 is located will still intersect with the vertical plane. At this time, the grounding ring 23 can be rotated around the second hinge axis 32 to make the plane where the grounding ring 23 is located a vertical plane, thus facilitating the connection of the grounding wire.

[0034] The anti-toppling power supply device of the present invention can be conveniently connected to the wire 41 through the wiring assembly, and then two-axis adjustment is realized through the first hinge axis 31 and the second hinge axis 32, so that the plane where the grounding ring 23 is located is a vertical plane, thus facilitating the connection of the grounding wire.

[0035] As a preferred embodiment, referring to Figure 2 , the number of the connecting plates 21 is two, the two connecting plates 21 are arranged at intervals, the intermediate connecting member 22 is located between the two connecting plates 21, and the first hinge axis 31 sequentially passes through one connecting plate 21, the intermediate connecting member 22 and the other connecting plate 21. The above is the specific connection manner of the connecting plate 21 and the intermediate connecting member 22 in this embodiment. By such a setting method, the connection reliability between the intermediate connecting member 22 and the connecting plate 21 can be improved.

[0036] Preferably, referring to Figure 2 , two lug ears 231 are provided on the grounding ring 23, the intermediate connecting member 22 is located between the two lug ears 231, and the second hinge axis 32 is adapted to sequentially pass through one lug ear 231, the intermediate connecting member 22 and the other lug ear 231. The above is the specific connection manner of the grounding ring 23 and the intermediate connecting member 22 in this embodiment. By providing two lug ears 231 for hinge cooperation, the influence on the grounding ring 23 body can be reduced.

[0037] Preferably, referring to Figure 4-5, a receiving hole 114 is further formed in the wiring body 11. The receiving hole 114 is located on one side of the sliding groove 111. A check block 115 and an elastic member 116 are arranged in the receiving hole 114. The elastic member 116 is adapted to abut the check block 115 against the pressing block 12 to prevent the pressing block 12 from moving away from the wire pressing hole 112. That is, by providing the check block 115, the loosening of the pressing block 12 can be avoided, thereby improving the connection reliability between the anti-backward power supply device of the present invention and the wire 41. It should be noted that the anti-backward principle of the check block 115 is realized by providing inclined teeth on the mating surfaces of the pressing block 12 and the check block 115, and its function is similar to that of a ratchet and pawl structure.

[0038] Preferably, referring to Figure 2 , a support surrounding frame 117 is arranged on the wiring body 11. The support surrounding frame 117 is used to limit the movement of the pressing block 12 along the depth direction of the sliding groove 111. By such a setting method, the pressing block 12 can be prevented from falling off from the sliding groove 111, thereby further improving the reliability of use.

[0039] Preferably, first anti-slip lines are arranged in the wire pressing hole 112. By arranging the first anti-slip lines, the phenomenon of the wire 41 slipping in the wire pressing hole 112 can be reduced, thereby improving the reliability of use.

[0040] Preferably, one end of the pressing block 12 facing the wire pressing hole 112 is in a concave arc shape, and second anti-slip lines are arranged at one end of the pressing block 12 facing the wire pressing hole 112. By the above setting method, the pressing block 12 can be more fitted with the wire 41, and at the same time, the second anti-slip lines are arranged on the pressing block 12 to further improve the reliability of the pressing block 12 pressing the wire 41.

[0041] Preferably, referring to Figure 1 , a first detachable insulating housing 14 is arranged on the wiring assembly. Through the first detachable insulating housing 14, a certain protection effect can be achieved, reducing electric shock accidents. At the same time, the first detachable insulating housing 14 also plays a role in protecting its internal structure and extending the service life. It should be noted that the purpose of being detachable is to allow the wire 41 to be smoothly inserted into the wire pressing hole 112.

[0042] Preferably, continuing to refer to Figure 1 , a second detachable insulating housing 24 is arranged on the grounding assembly. Specifically, referring to Figure 1-3 and Figure 6-7, the grounding ring 23 is trapezoidal, and the second detachable insulating housing 24 includes a fixed housing 241 and a detachable housing 242. The fixed housing 241 surrounds the top edge and both side edges of the grounding ring 23. The detachable housing 242 includes a first semi-tubular housing 2421 and a second semi-tubular housing 2422. The first end of the first semi-tubular housing 2421 is hinged to the fixed housing 241, and the first end of the second semi-tubular housing 2422 is hinged to the fixed housing 241. The first ends of the first semi-tubular housing 2421 and the second semi-tubular housing 2422 face the same direction. The first semi-tubular housing 2421 and the second semi-tubular housing 2422 are respectively disposed on both sides of the bottom edge of the grounding ring 23, and the first semi-tubular housing 2421 and the second semi-tubular housing 2422 can be mutually clamped. Handles 243 are provided on both the first semi-tubular housing 2421 and the second semi-tubular housing 2422. Similarly, by providing the second detachable insulating housing 24, it can play a role in protecting its internal structure and reducing the occurrence of electric shock accidents.

[0043] Specifically, when it is necessary to hang the grounding wire, the first semi-tubular housing 2421 and the second semi-tubular housing 2422 are separated through the handle 243, so as to expose the conductive part for hanging the grounding wire conveniently. When it is not necessary to hang the grounding wire, the first semi-tubular housing 2421 and the second semi-tubular housing 2422 are clamped to surround the conductive part, preventing birds, kite strings, fishing lines, etc. from touching it and causing electric shock accidents.

[0044] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
