Description

Technical Field

[0001] The invention relates to power distribution construction technology, and in particular to a grounding lead device for power distribution network construction. Background Art

[0002] The distribution network refers to the power grid that receives electric energy from the transmission network or regional power plants and distributes it locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, towers, distribution transformers, electric poles, disconnectors, reactive power compensators and some ancillary facilities. When the distribution transformer is installed, it is usually supported and fixed by multiple sets of corner poles installed on the electric poles. In order to ensure the safety of the distribution transformer and the distribution network during the power transmission process and reduce the risk of electric shock, it is generally necessary to perform working grounding.

[0003] During the working grounding process of the distribution transformer and the distribution network, the working grounding wire of the neutral point on the low-voltage side of the transformer is usually connected to the grounding bar, and the grounding wire on the lightning arrester above the transformer is also connected to the grounding bar, so that the distribution transformer and the distribution network are safer in subsequent work, and the probability of electric shock accidents is effectively reduced. However, in actual application, the distribution transformer is mostly set outdoors, and the grounding wire and the grounding bar on the transformer and the lightning arrester are exposed to the external environment. Therefore, in the long-term working process, the fine sand or dust from the outside will directly adhere to the bolts and nuts used to connect the grounding wire and the grounding bar. The adhesion of fine sand or dust will form an uneven protective layer on the surface of the bolts and nuts, resulting in easy retention of moisture, especially in the thread grooves on the bolts and nuts, making the bolts and nuts prone to rust, and the rust generated will also spread to the grounding wire and the grounding bar to a certain extent, which not only increases the grounding resistance between the grounding wire and the grounding point of the distribution network, but also causes the connection of the grounding connection point to loosen and accelerates the rust of the connection point, making it impossible for the working grounding device to effectively protect the transformer and the distribution network from working grounding.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Embodiment 1:

[0038] See also Figure 1-Figure 7 A grounding lead device for distribution network construction includes a vertical plate 1 and a grounding wire 101 connected to the vertical plate 1. A protection box 2 is installed on one side of the vertical plate 1. The protection box 2 includes a fixed box body 21 and a movable box body 22;

[0039] The inner wall of the fixed box body 21 is fixedly connected with a receiving bar 3, a grounding bar 31 is installed on the surface of the receiving bar 3, a grounding lead 32 is fixedly connected to the bottom end of the grounding bar 31, the grounding lead 32 is insulated outside, a plurality of groups of mounting screw holes 33 are evenly spaced on the surface of the grounding bar 31 along its length direction, a connecting ring piece 34 is fixedly connected to the end of the grounding wire 101, a mounting bolt 35 is connected to the inner thread of the mounting screw hole 33, and a semicircular groove 36 respectively adapted to the grounding wire 101 and the grounding lead 32 is opened on one side of the fixed box body 21 and the movable box body 22, and a sealing gasket 37 is installed on the inner wall of the semicircular groove 36;

[0040] A locking unit is provided between the fixed box body 21 and the movable box body 22, and the locking unit is used to connect and fix the fixed box body 21 and the movable box body 22;

[0041] A connection unit is provided on the other side of the vertical plate 1, and the connection unit is used to connect and fix the vertical plate 1 to the electric pole.

[0042] In this embodiment, the locking unit includes right-angle grooves 4 respectively opened on both sides of the interior of the movable box body 22, the inner side surface of the right-angle groove 4 is slidably connected with a right-angle plate 41, the interior of the movable box body 22 is rotatably connected with a transmission gear 42, and the outside of the right-angle plate 41 is provided with transmission teeth 43. The two right-angle plates 41 are respectively meshed with the upper and lower sides of the transmission gear 42 through the transmission teeth 43, and the bottoms of the two right-angle plates 41 on the side away from each other are fixedly connected with a clamping block 44, and the surface of the fixed box body 21 is provided with a straight groove 45 connected to the right-angle groove 4, and the side of the inner wall of the straight groove 45 is provided with a clamping groove 46 adapted to the clamping block 44.

[0043] It should be added that the size of the straight groove 45 is consistent with the size of the vertical portion of the right-angle groove 4, and the size of the straight groove 45 is compatible with the block 44. The block 44 can move along the inner wall of the straight groove 45 to its inner end and translate into the inside of the slot 46.

[0044] In addition, the outside of the movable box body 22 is rotatably connected to an adjusting wheel 47 which is coaxially arranged with the transmission gear 42, and the surface of the movable box body 22 is fixedly connected to an anti-skid rubber pad 48 corresponding to the adjusting wheel 47. The anti-skid rubber pad 48 is provided to increase the rotational friction resistance between the adjusting wheel 47 and the surface of the movable box body 22, so that the resistance of the adjusting wheel 47 during rotation is greater, so that it can always maintain a stable state during normal operation.

[0045] In this embodiment, the connecting unit includes a fixing seat 5 symmetrically fixedly connected to the upper and lower ends of the surface of the vertical plate 1, and a plurality of connecting slots 51 are symmetrically provided on both sides of the surface of the fixing seat 5. Arc-shaped locking hoops 52 are symmetrically connected to the two sides of the outside of the fixing seat 5. Both ends of the arc-shaped locking hoops 52 are fixedly connected to fixing plates 53. The surfaces of the fixing plates 53 and the surfaces of the fixing seat 5 are provided with matching connecting slots 54. The connecting slots 54 on the fixing seat 5 pass through all the connecting slots 51. The size of the connecting slots 51 matches the fixing plates 53. The two fixing plates 53 are connected and fixed by connecting bolts 55 and connecting nuts 56.

[0046] It should be noted that when connecting the arc-shaped locking hoops 52, one end of the two arc-shaped locking hoops 52 is symmetrically inserted into the connecting slots 51 at symmetrical positions on the fixing base 5, and then the connecting bolts 55 are inserted from the connecting groove 54 port on one side of the fixing base 5 and extended from the other side of the fixing base 5, and then the connecting nuts 56 are tightened on the outside of the connecting bolts 55 to fix the two arc-shaped locking hoops 52.

[0047] During installation, the operator fits the arc-shaped locking hoops 52 on both sides to the appropriate positions on the electric pole, and then connects the fixing plates 53 on one side of the two arc-shaped locking hoops 52 by connecting bolts 55 and connecting nuts 56, and then inserts the fixing plate 53 on the other side into the connecting slot 51 on the fixing seat 5, and connects and fixes the fixing plate 53 on this side and the fixing seat 5 again by connecting bolts 55 and connecting nuts 56, thus completing the connection of the opposing plates 1;

[0048] After the vertical plate 1 is connected, the operator aligns the connection ring piece 34 at the end of the grounding wire 101 to be connected with the mounting screw hole 33 on the grounding bar 31 inside the fixed box body 21, and passes the end of the mounting bolt 35 through the connection ring piece 34 and is threadedly connected with the mounting screw hole 33, so that the grounding wire 101 can be connected to the grounding bar 31. After the grounding wire 101 is connected, the operator clamps the grounding wire 101 into the corresponding semicircular groove 36 on the fixed box body 21;

[0049] Afterwards, the operator aligns the movable box body 22 with the fixed box body 21 so that the end of the right-angle plate 41 and the block 44 can move into the straight groove 45, and then the operator turns the adjusting wheel 47, and the adjusting wheel 47 rotates to drive the transmission gear 42 to rotate. With the cooperation of the transmission teeth 43, the transmission gear 42 rotates to drive the right-angle plates 41 on both sides to move away from each other. When the right-angle plates 41 move, they drive the block 44 to move, so that the block 44 moves into the slot 46, thereby completing the connection between the movable box body 22 and the fixed box body 21.

[0050] Embodiment 2:

[0051] See also Figure 8 This embodiment provides a technical solution based on the above embodiment. The inner wall of the movable box body 22 is fixedly connected with right-angle guide plates 6 located on both sides of the semicircular groove 36. A guide groove 61 is formed between the right-angle guide plate 6 and the inner wall of the movable box body 22. The inner side surfaces of the guide grooves 61 on both sides are slidably connected with the same sealing plate 62. An extrusion spring 63 is fixedly connected between the end of the sealing plate 62 away from the semicircular groove 36 and the inner wall of the movable box body 22.

[0052] It should be added that the size of the sealing plate 62 corresponds to the semicircular groove 36 , and the sealing plate 62 can be moved to seal the upper and lower semicircular grooves 36 after assembly.

[0053] After the movable box body 22 is assembled with the fixed box body 21, when there is no grounding wire 101 inside the semicircular groove 36 at the position corresponding to the sealing plate 62, the assembly of the movable box body 22 and the fixed box body 21 will cause the sealing plate 62 to simultaneously close the two semicircular grooves 36 after splicing there. When the grounding wire 101 is provided there, when the movable box body 22 is close to the fixed box body 21, the movement of the sealing plate 62 is hindered, causing it to slide along the inner wall of the guide groove 61 and compress the extrusion spring 63, so that it will not hinder the normal routing of the grounding wire 101.

[0054] Embodiment 3:

[0055] See also Fig. 9 This embodiment provides a technical solution based on the above embodiments. A receiving groove 7 is provided on the surface of the movable box body 22. A desiccant box 71 is embedded in the inner wall of the receiving groove 7. The interior of the desiccant box 71 is filled with desiccant material. Corresponding vents 72 are provided on the top of the desiccant box 71 and the inner wall of the receiving groove 7. The vents 72 located inside the receiving groove 7 are connected to the interior of the movable box body 22.

[0056] It should be additionally explained that the outer side of the moisture absorption box 71 is provided with a sealing anti-slip cover.

[0057] During the installation process, the desiccant box 71 filled with desiccant material is inserted into the receiving groove 7 on the movable box body 22, and with the cooperation of the sealing and anti-slip cover, the connection between the desiccant box 71 and the movable box body 22 is relatively stable. In the subsequent working process, through the mutual cooperation between the desiccant box 71 and the vent 72 on the receiving groove 7, the residual moisture inside the protective box 2 can be removed by the desiccant material in the desiccant box 71, so that the inside of the protective box 2 can always remain dry.

[0058] Embodiment 4:

[0059] Please refer to 4. Fig. 9 This embodiment provides a technical solution based on the above embodiment. A sealing baffle 8 is provided on the outer side of the assembly end surface of the fixed box body 21, and a sealing baffle groove 81 matched with the sealing baffle 8 is provided on the outer side of the assembly end surface of the movable box body 22. The sealing baffle 8 can be inserted into the sealing baffle groove 81.

[0060] It should be noted that, through the mutual cooperation between the sealing baffle 8 and the sealing baffle groove 81, not only can the internal sealing of the movable box body 22 and the fixed box body 21 be better after assembly, but the two can also be easily aligned during assembly, thereby making the assembly of the protective box 2 more convenient.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
