Description

Technical Field

[0001] This invention relates to the field of conductive technology, and more specifically to a grounding grid connection device that is easy to construct. Background Technology

[0002] As an important safety protection facility in power systems and communication base stations, the grounding grid's main function is to safely introduce fault current or lightning current into the earth, thereby protecting equipment and personnel. The grounding grid is usually composed of multiple galvanized flat steel bars connected to each other, and needs to be reliably electrically connected to grounding rods (such as copper-clad steel grounding rods or galvanized grounding rods) inserted deep into the soil to reduce grounding resistance and improve current dissipation capacity. Currently, the connection between the flat steel bars and the grounding rods is mainly achieved by welding, such as electric welding or hot-melt welding.

[0003] When laying grounding grids in mountainous areas, there may be rocks deep in the soil, preventing the grounding rods from fitting snugly against the grid and creating a gap between them. Welding requires cutting conductive plates of appropriate length to connect the two, then relying on skilled welders using welding equipment and tools. The process involves multiple steps before and after welding, including positioning, fixing, and slag removal, which is time-consuming and difficult to achieve quickly. Furthermore, the flat steel has a near-rectangular cross-section, while the grounding rod is mostly circular, often resulting in only point or line contact after welding. This small contact area can easily lead to increased local resistance and affect the grounding effect. Therefore, we propose a grounding grid connection device that is easy to construct. Summary of the Invention

[0004] The purpose of this invention is to provide a grounding grid connection device that is easy to construct, in order to solve the problems mentioned in the background art, such as the grounding rod and grounding grid being fixed by welding, which requires professional personnel, is time-consuming and laborious to operate, and results in high grounding resistance after welding.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grounding grid connection device that is easy to construct, comprising:

[0006] A conductive plate, wherein a clamping assembly is slidably connected along its long side, the clamping assembly being used to press the flat steel constituting the grounding grid against the conductive plate;

[0007] A clamping assembly is detachably connected to one end of the conductive plate, and a grounding rod is clamped inside the clamping assembly;

[0008] The clamping assembly includes an adjusting block, a guide slider, and a clamping block. At least two of the adjusting blocks are slidably disposed on the conductive plate. The clamping block is connected to the lower surface of the adjusting block through the guide slider. The clamping block is used to press and fix the flat steel against the conductive plate. There is an adjusting member between the two adjusting blocks to adjust the spacing.

[0009] Preferably, the clamping block includes an inclined portion and a horizontal portion, the inclined portion is fixed to the lower surface of the guide slider, and one end of the inclined portion is integrally formed with a horizontal portion parallel to the conductive plate.

[0010] Preferably, the adjusting component includes one or more of the following: adjusting bolt, spring, and wire rope.

[0011] Preferably, the inner side of the adjusting block has a through hole that mates with the adjusting bolt.

[0012] Preferably, the clamping assembly includes a clamping block, a conductive groove, and a limiting pin. A connecting block is fixed to one side wall of the clamping block, and a connecting groove is formed on one end face of the connecting block. A connecting slider that can slide into the connecting groove is fixed to one end of the conductive plate. The conductive groove is formed on the other side wall of the clamping block to correspond to the grounding rod. The limiting pin is slidably disposed inside the conductive groove, and one end of the limiting pin cooperates with the connecting slider to restrict the movement of the connecting slider.

[0013] Preferably, the limiting pin includes an arc-shaped plate and a pin rod. The arc-shaped plate is disposed in the groove of the inner wall of the conductive groove, and the pin rod is fixed to one side wall of the arc-shaped plate. One end of the pin rod cooperates with a pin groove opened on one side wall of the connecting slider.

[0014] Preferably, ear plates are fixed to both ends of the clamping block, and clamping bolts are provided on the inner side of the ear plates. The two clamping blocks are clamped and fixed to the grounding rod by clamping bolts.

[0015] Preferably, a stop block for positioning the connecting slider is fixed at one end of the inner side of the connecting groove.

[0016] Preferably, at least two sets of connecting sliders are provided.

[0017] Preferably, a guide groove is provided in the middle of the inner side of the conductive plate, and at least three guide sliders are evenly distributed along the long side of the adjusting block, and at least one of the guide sliders corresponds to the guide groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) This invention, by setting up a conductive plate, a pressing component, a clamping component, an adjusting block, a guide slider and a pressing block, avoids the traditional method of welding, which requires professional personnel and tools and results in a small contact area after welding, affecting resistivity. This invention has a rigid structure with high strength. During assembly, standard parts can be pre-produced and then installed on-site. Ordinary operators can install it, making the operation simple and efficient. After installation, there is a large conductive contact area between the grounding grid and the grounding rod, which can well ensure the grounding resistivity.

[0020] (2) By setting limit pins and multiple connecting sliders, the position of the clamping component can be adjusted adaptively according to the actual position of the grounding rod, thereby avoiding the clamping component being located only along the long side of the conductive plate. In this device, the clamping component can be arranged on the side wall of the conductive plate, thereby improving the coordination effect between the clamping component and different external grounding rod positions. It can also adjust the conductive plate from horizontal to vertical, which is conducive to connecting with the flat steel of the horizontal or vertical grounding grid, thus improving the practicality of the device.

[0021] (3) By setting up horizontal and inclined parts, it is not necessary to drill holes first when connecting flat steel and conductive plate, and then use the holes and fixing bolts to achieve the connection and fixation of the two. This device does not require drilling when connecting. Just adjust the distance between the two adjustment blocks to quickly press the conductive plate onto the flat steel, improve installation efficiency, and reduce the reduction of conductive area caused by drilling, which is conducive to ensuring stable grounding and conductivity.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-11 This invention provides a technical solution: a grounding grid connection device that is easy to construct, comprising:

[0036] The conductive plate 2 has a pressure-fixing component 3 slidably connected along its long side. The pressure-fixing component 3 is used to press the flat steel 1 that forms the grounding grid against the conductive plate 2.

[0037] The conductive plate 2 is preferably made of metal;

[0038] The clamping assembly 5 is detachably connected to one end of the conductive plate 2, and a grounding rod 4 is clamped inside the clamping assembly 5;

[0039] The grounding grid is composed of multiple flat steel bars 1 connected to each other. This device facilitates the electrical connection between the flat steel bars 1 and the grounding rod 4 through the conductive plate 2, so that the grounding current of the grounding grid can be better introduced into the soil by inserting the grounding rod 4 deeper into the soil.

[0040] The clamping assembly 3 includes an adjusting block 31, a guide slider 32, and a clamping block 33. At least two adjusting blocks 31 are slidably disposed on the conductive plate 2, so that they can be distributed along both sides of the flat steel 1 through two symmetrical adjusting blocks 31. The clamping block 33 is connected to the lower surface of the adjusting block 31 through the guide slider 32, and the flat steel 1 is pressed and fixed against the conductive plate 2 through the clamping block 33. There is an adjusting member between the two adjusting blocks 31 to adjust the spacing.

[0041] This avoids the reliance on professional personnel and specialized tools required by traditional welding methods, such as Figure 1 and Figure 2As shown, this invention uses pre-produced standard accessories, allowing ordinary operators to complete the installation during on-site construction. The operation is simple and efficient. During use, the distance between the two adjusting blocks 31 is adjusted by adjusting the adjusting component, which in turn moves the two clamping blocks 33 closer or further apart. When they are close together, they move against the flat steel 1 towards the conductive plate 2 until they come into close contact to achieve grounding and conductivity. When they are far apart, the connection between the flat steel 1 and the conductive plate 2 can be released for easy disassembly, replacement and maintenance later. In addition, some existing technologies use drilling and bolt fixing to connect the flat steel and the conductive plate. However, drilling requires professional tools and reduces the conductive cross-sectional area. The contact conductive area between the flat steel and the grounding rod with different cross-sections is also small, resulting in high resistance. Precise alignment is also required during connection.

[0042] Preferably, the clamping block 33 includes an inclined portion 331 and a horizontal portion 332. The inclined portion 331 is fixed to the lower surface of the guide slider 32, and one end of the inclined portion 331 is integrally formed with a horizontal portion 332 parallel to the conductive plate 2.

[0043] like Figure 3 As shown, the flat steel 1 can move towards the conductive plate 2 by contacting the two inclined portions 331 on both sides, thereby making it contact and fix it with the conductive plate 2, forming a large contact conductive area. The long sides of the two inclined portions 331 limit the side contact of the flat steel 1, which can prevent the flat steel 1 from twisting with the conductive plate 2, improve the stable fixing effect between the two, and ensure stable grounding conductivity. Furthermore, the horizontal portion 332 can prevent the flat steel 1 from falling directly when it accidentally detaches from the conductive plate 2. At this time, the clamping component 3 itself can still maintain the grounding path through its conductive material, forming a double safety guarantee.

[0044] Preferably, the adjusting component includes one or more of the following: adjusting bolt 34, spring, and wire rope;

[0045] The spacing between the two adjusting blocks 31 is easily adjustable, thereby allowing the two clamping blocks 33 to be moved closer or further apart. Whether using threaded locking, elastic clamping, or flexible tensioning, the spacing between the two adjusting blocks 31 can be easily adjusted, thereby controlling the clamping force of the clamping blocks 33 on the flat steel 1. This adapts to different construction scenarios and operating habits. Furthermore, when using a spring, both ends of the spring can be fixed to the two adjusting blocks 31, so that the spring force can pull the two adjusting blocks 31 closer together to adjust the spacing. When using a wire rope, one end of the wire rope can be fixed to one side wall of the adjusting block 31, and the other end of the wire rope can pass through the inside of another adjusting block 31. By pulling the wire rope, the adjusting block 31 can be moved closer to the other adjusting block 31, thereby adjusting the spacing.

[0046] Preferably, the adjusting block 31 has a through hole 35 on its inner side that mates with the adjusting bolt 34;

[0047] like Figure 2 and Figure 4 As shown, by rotating the nut of the adjusting bolt 34, the two adjusting blocks 31 are pushed closer together until the clamping block 33 presses the flat steel 1 onto the conductive plate 2, achieving quick locking and fixing. The structure is simple and reliable, with a large locking force, and is easy to disassemble and maintain.

[0048] Preferably, the clamping assembly 5 includes a clamping block 51, a conductive groove 56, and a limiting pin 57. A connecting block 54 is fixed to one side wall of the clamping block 51. A connecting groove 55 is opened on one end face of the connecting block 54. A connecting slider 22 that can slide into the inner side of the connecting groove 55 is fixed to one end of the conductive plate 2. The conductive groove 56 is opened on the other side wall of the clamping block 51 to correspond to the grounding rod 4. The inner wall of the conductive groove 56 is arc-shaped, which facilitates good contact with the grounding rod 4 with a circular cross-section, thereby increasing the conductive area and ensuring a stable grounding effect. One end of the limiting pin 57 cooperates with the connecting slider 22 to restrict the movement of the connecting slider 22.

[0049] like Figure 6 and Figure 7 As shown, by inserting the connecting slider 22 into the inner side of the connecting groove 55, and then inserting the limiting pin 57 from one side wall of the conductive groove 56 into the inner side of the connecting slider 22, the connecting slider 22 and the clamping block 51 can be quickly connected and fixed. In the later stage, this structure facilitates the adjustment of the position of the clamping block 51, so that the clamping block 51 can match the grounding rod 4 at different external positions. At the same time, the conductive plate 2 can be adjusted from horizontal to vertical to adapt to the horizontal or vertical arrangement of the flat steel 1.

[0050] Preferably, the limiting pin 57 includes an arc plate 571 and a pin 572. The arc plate 571 is disposed in the groove of the inner wall of the conductive groove 56, and the pin 572 is fixed to one side wall of the arc plate 571. One end of the pin 572 cooperates with the pin groove opened on one side wall of the connecting slider 22.

[0051] like Figure 7 , Figure 8 and Figure 9 As shown, during assembly, the arc plate 571 can be manually inserted into the inside of the groove so that one side wall of the arc plate 571 is flush with the inner wall of the conductive groove 56, thus preventing the outer surface of the grounding rod 4 from contacting the protrusion of the inner wall of the conductive groove 56. Furthermore, after the two clamping blocks 51 clamp the grounding rod 4 in the later stage, the arc plate 571 can be prevented from accidentally coming out of the inside of the groove, thereby allowing the pin 572 to be firmly inserted into the pin groove, restricting the movement of the connecting slider 22, and ensuring the stability of the connection between the clamping block 51 and the conductive plate 2.

[0052] When changing the position of clamp 51 later, the two clamps 51 can be separated from each other and detached from the grounding rod 4 by loosening the clamping bolt 53. At this time, the arc plate 571 can be pulled out from the inside of the groove, thereby pulling the pin 572 out from the inside of the connecting slider 22. Then the position of clamp 51 can be adjusted to cooperate with the other connecting slider 22.

[0053] Preferably, ear plates 52 are fixed to both ends of the clamping block 51, and clamping bolts 53 are provided on the inner side of the ear plates 52. The two clamping blocks 51 are clamped and fixed to the grounding rod 4 by the clamping bolts 53.

[0054] like Figure 5 As shown, the grounding rod 4 can be quickly clamped and fixed by the two clamping blocks 51 approaching each other. The inner wall of the conductive groove 56 is arc-shaped, forming a large contact area with the circular cross-section grounding rod 4, resulting in good conductivity.

[0055] Preferably, a stop block for positioning the connecting slider 22 is fixed at one end of the inner side of the connecting groove 55;

[0056] like Figure 6 and Figure 7 As shown, this allows for positioning of one end of the connecting slider 22 after it is inserted into the inner side of the connecting groove 55, ensuring that the pin 572 can be properly inserted into the inner side of the pin groove. At the same time, the stop block can prevent the connecting slider 22 from accidentally sliding out of one end of the connecting groove 55.

[0057] Preferably, the connecting slider 22 is provided in four sets, and at least two sets are parallel to one long side of the conductive plate 2;

[0058] like Figure 9 As shown, the multi-position layout of the connecting sliders 22 allows the clamping assembly 5 to be fixed by selecting different connecting sliders 22 as needed, thereby flexibly adjusting the position of the clamping assembly 5 on the conductive plate 2 to better match the orientation of the external grounding rod 4. In addition, the conductive plate 2 can be changed from a horizontal state to a vertical state by using connecting sliders 22 in different directions to adapt to flat steel 1 with different orientations, significantly improving the versatility of the device. Figure 1 The diagram shown illustrates the first state of connection between the grounding grid and grounding rod 4 via this device. Figure 10 The image shown is a diagram of the second state. Figure 11 The image shown is a diagram of the third state.

[0059] Preferably, a guide groove 21 is provided in the middle of the inner side of the conductive plate 2, and at least three guide sliders 32 are evenly distributed along the long side of the adjusting block 31, and at least one guide slider 32 corresponds to the guide groove 21.

[0060] like Figure 4 and Figure 5As shown, after the position of the adjusting block 31 is adjusted, the clamping block 33 can be moved in a good manner. The multiple guide sliders 32 can ensure the connection strength between the clamping block 33 and the adjusting block 31. The cooperation between the guide groove 21 and the guide slider 32 can keep the two adjusting blocks 31 in a parallel state, so as to better abut against the two parallel sides of the flat iron.

[0061] The working principle and usage process of this invention are as follows: In use, according to the installation position of the flat steel 1 and the grounding rod 4, the clamping block 51 at one end of the conductive plate 2 is made to cooperate with one side of the grounding rod 4, and then another clamping block 51 is placed on the other side of the grounding rod 4. The two clamping blocks 51 are connected by clamping bolts 53 to hold the grounding rod 4 tightly and achieve fixation. The two adjusting blocks 31 slide along the conductive plate 2 to be arranged on both sides of the flat steel 1. The distance between the two adjusting blocks 31 is reduced by adjusting bolts 34, so that the flat steel 1 is held tightly by the pressing block 33. Since the inclined part 331 of the pressing block 33 is inclined, the flat steel 1 can be pressed tightly onto the conductive plate 2, thereby achieving a fixed cooperation between the flat steel 1 and the conductive plate 2 and completing the connection. This allows the flat steel 1 of the grounding grid to better conduct the grounding current into the soil depth through the grounding rod 4 deeply inserted into the soil.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
