Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite wallboard assembly, in particular to a modular substation composite wallboard connecting mechanism. BACKGROUND

[0002] Under the background of the accelerated construction of smart grids and new power systems, modular substations have become an important development direction for power infrastructure construction due to their prefabrication, assembly, and integration advantages, which effectively shorten the construction period and reduce operation and maintenance costs. As a key component of modular substations, composite wallboards and their connecting structures not only bear multiple functions such as wall structure bearing, sealing protection, and seismic and wind resistance, but also directly affect the overall safety, durability, and assembly efficiency of the substation.

[0003] In the construction of modular substations, composite wallboards are key components for building building envelope structures of substations, and the rationality and reliability of their connecting technology are crucial. Currently, the connecting methods of composite wallboards for modular substations mainly include various mechanical fastening, mortise and tenon splicing, and bonding, etc. to fix the composite wallboards on the foundation or adjacent composite wallboards to realize the construction of the structure. For example, some technologies use aluminum alloy frames to seal the edges, use self-tapping screws to fasten the double-sided fiber cement veneer and the structure filled with rock wool in the middle, and some use profile frames to insert the panel fixing part into the slotted side of the panel. These connecting technologies to some extent meet the basic installation needs of composite wallboards and realize the construction of wall structures.

[0004] However, the existing connecting technology has significant defects. Most connecting mechanisms only focus on the physical fixation of composite wallboards, but ignore the key considerations of electrical performance. When the substation is in a complex electromagnetic environment, the surface of the composite wallboard is easy to accumulate a large amount of electric charge due to static induction and equipment operation, forming a high static potential. When the electric charge accumulates to a certain extent, a significant potential difference will occur between the composite wallboard and the surrounding objects or equipment, which may cause discharge. This discharge not only may interfere with the normal operation of precision electronic equipment in the substation, causing data transmission errors, equipment malfunctions, etc., but in extreme cases, it may also cause electrical fires, posing a serious threat to the safe operation of the substation.

[0022] As Figures 1-7As shown, the modular substation composite wallboard connecting mechanism provided by the application comprises a connecting column 101, the side wall of the connecting column 101 is provided with a first clamping groove 102, the first clamping groove 102 is clamped with one side of the composite wallboard 1, the first clamping groove 102 prevents the composite wallboard 1 from moving in the direction perpendicular to the plate surface of the composite wallboard 1 itself, further comprising a clamping strip 103 and a pressing mechanism, the clamping strip 103 is arranged on the inner wall of the first clamping groove 102, the length direction of the clamping strip 103 is parallel to the length direction of the connecting column 101, the composite wallboard 1 is provided with a second clamping groove 104 in the length direction of the connecting column 101, the clamping strip 103 is clamped in the second clamping groove 104, and the clamping strip 103 is used to prevent the composite wallboard 1 from moving in the width direction of the connecting column 101; the pressing mechanism comprises a pressing block 105, a connecting rod mechanism and a top block 106, the pressing block 105 is arranged at the bottom end of the connecting column 101, one end of the connecting rod mechanism is connected with the pressing block 105, the other end of the connecting rod mechanism is connected with the top block 106, the top block 106 has electrical conductivity, and the top block 106 is electrically connected with the ground wire of the substation; when the composite wallboard 1 is clamped into the first clamping groove 102, the bottom end of the composite wallboard 1 is pressed on the pressing block 105, the pressing block 105 drives the top block 106 to move through the connecting rod mechanism, so that the top block 106 is pressed on the conductive sheet 107 on one side of the composite wallboard 1, and the pressure applied by the top block 106 to the conductive sheet 107 is towards the clamping strip 103.

[0023] The working principle of the above embodiment will be briefly described as follows: First, the foundation installation link is carried out: the connecting column 101 is fixedly connected on the foundation 404 of the substation through the bolt 8, and the connecting column 101 needs to be arranged in the vertical direction to provide a stable support foundation for the subsequent installation of the composite wallboard.

[0024] Then, the composite wallboard installation stage is entered: one side of the composite wallboard 1 is inserted into the first clamping groove 102 on the connecting column 101 in the length direction (i.e. the vertical direction) of the connecting column 101. In this process, the clamping strip 103 on the inner wall of the first clamping groove 102 will be accurately clamped into the second clamping groove 104 on the composite wallboard 1, and a limiting structure is initially formed to prevent the composite wallboard from deviating horizontally during the insertion process.

[0025] When the composite wallboard 1 is continuously inserted to the bottom end abutting against the pressing block 105, the following effects will be generated: the bottom end of the composite wallboard 1 applies downward pressure to the pressing block 105 to drive the pressing block 105 to move downward along the connecting column 101. The downward movement of the pressing block 105 transmits power through the connecting rod mechanism to drive the top block 106 to move towards the side of the clamping strip 103, at this time, the top block 106 begins to approach the composite wallboard 1 to prepare for the subsequent electrical connection. When the bottom end of the composite wallboard 1 finally contacts the foundation 404, it indicates that the installation is in place, and at this time, the double functional effects are achieved:

[0026] First, in the mechanical limiting level: the bottom end driving block 105 of the composite wallboard 1 moves to the bottom end of the connecting column 101, and the connecting rod mechanism synchronously drives the top block 106 to move to be pressed on the conductive strip of the composite wallboard 1. At this time, the top block 106 applies pressure to the conductive sheet 107 in the direction thereof, so that the second clamping groove 104 on the composite wallboard 1 is tightly fitted with the clamping strip 103, and the limiting effect of the clamping strip 103 effectively prevents the displacement of the composite wallboard 1 along the width direction of the connecting column 101, and ensures the mechanical stability of the overall structure; second, in the conductive connection level: since the top block 106 is conductive and is electrically connected with the ground wire of the transformer substation, the conductive sheet 107 of the composite wallboard 1 forms a stable electrical connection path with the ground wire of the transformer substation through the top block 106. This design not only realizes the mechanical fixation of the composite wallboard, but also constructs a reliable grounding conductive system, which can timely guide away the static electricity or leakage current that may be generated by the composite wallboard, improve the power utilization safety factor of the transformer substation, and at the same time avoid equipment failure or safety hazards caused by static electricity accumulation.

[0027] Through the complete operation process and function realization, the connecting mechanism realizes the stable installation and limiting of the composite wallboard in the mechanical structure, and constructs a safe and reliable grounding path in the electrical function, and has structural stability and electrical safety, which can effectively meet the dual needs of wall connection and safe grounding in the construction of the transformer substation.

[0028] The modular composite wallboard connecting mechanism for the transformer substation can connect the composite wallboard 1 to the foundation 404 while ensuring that the conductive sheet 107 in the composite wallboard 1 is stably electrically connected with the ground wire of the transformer substation, thereby ensuring that the static electricity and induced charge on the composite wallboard 1 are quickly discharged, and avoiding the discharge phenomenon caused by potential difference.

[0029] On the basis of the above embodiment, in order to ensure that the top block 106 is tightly fitted with the conductive sheet 107 and ensure the stability of the electrical connection between the conductive sheet 107 in the composite wallboard 1 and the ground wire of the transformer substation.

[0030] As shown in Figures 2-4 and Figure 6 , wherein the connecting rod mechanism comprises a pull rod 201, the connecting column 101 is provided with a first sliding hole 203 along the length direction thereof and a first sliding groove 204 along the width direction thereof, the pull rod 201 is slidingly connected in the first sliding hole 203, the pull rod 201 is tightly matched with the first sliding hole 203, the top block 106 is provided with a second sliding groove 202 along the length direction of the pull rod 201, the top block 106 is slidingly connected outside the pull rod 201 through the second sliding groove 202, the top block 106 is slidingly connected in the first sliding groove 204, and the side wall of the pull rod 201 is provided with a wedge surface 205; when the pull rod 201 moves towards one end of the pressing block 105, the top block 106 moves towards one side of the conductive sheet 107 under the action of the wedge surface 205 and the second sliding groove 202.

[0031] At the beginning, the pull rod 201 is located at the top of the first sliding hole 203, and due to the close fit between the pull rod 201 and the first sliding hole 203, the pull rod 201 can be prevented from sliding downward under the action of its own gravity, and the top block 106 can be prevented from being prematurely extended from the first sliding groove 204 to affect the installation of the composite wallboard 1. When the bottom end of the composite wallboard 1 drives the pressing block 105 to move towards the bottom end of the connecting column 101, the pressing block 105 drives the pull rod 201 to move towards the bottom end of the connecting column 101, and the pull rod 201 slides relative to the second sliding groove 202 on the top block 106. Until the wedge surface 205 on the pull rod 201 abuts against the edge of the second sliding groove 202, at this time, with the continuous movement of the pull rod 201 towards the bottom end of the connecting column 101, the wedge surface 205 drives the top block 106 to move along the length direction of the second sliding groove 202 towards the side of the composite wallboard 1 through the second sliding groove 202, and the pull rod 201 drives the top block 106 to move towards the side close to the composite wallboard 1, until the top block 106 is extended from the first sliding groove 204 and is pressed against the conductive sheet 107 of the composite wallboard 1, thereby ensuring that the top block 106 is closely attached to the conductive sheet 107, and ensuring the stability of the electrical connection between the conductive sheet 107 in the composite wallboard 1 and the ground wire of the transformer substation.

[0032] As a preferred solution, as shown in Figure 2 , Figure 3 and Figure 6 , wherein the top block 106 is provided with a conductive spring contact pin 3, and the conductive spring contact pin 3 can be extended and retracted along the width direction of the connecting column 101, one end of the conductive spring contact pin 3 abuts against the conductive sheet 107 of the composite wallboard 1, and the other end of the conductive spring contact pin 3 is electrically connected to the top block 106. By providing the conductive spring contact pin 3 on the top block 106, since the conductive spring contact pin 3 can be extended and retracted along the width direction of the connecting column 101, and the conductive spring contact pin 3 abuts against the conductive sheet 107 of the composite wallboard 1, even if the composite wallboard 1 slightly shakes relative to the connecting column 101, the stable electrical connection between the conductive sheet 107 of the composite wallboard 1 and the top block 106 can be ensured.

[0033] As a preferred solution, as shown in Figure 2 and Figure 7As shown in the drawing, the bottom end of the pull rod 201 is provided with a conductive plug 401, the ground 404 of the substation is provided with a conductive jack 402, the conductive jack 402 is electrically connected with the ground wire, the wedge surface 205 of the sidewall of the pull rod 201 is provided with a conductive contact block 403, the conductive contact block 403 is electrically connected with the conductive plug 401, when the composite wallboard 1 is driven by the pressing block 105 to move to the side close to the ground 404, the conductive plug 401 at the bottom end of the pull rod 201 is inserted into the conductive jack 402, at the same time, the conductive contact block 403 abuts against the conductive spring contact pin 3 and the top block 106 is pressed on the conductive sheet 107 of the composite wallboard 1. By setting the conductive plug 401 and the conductive jack 402, when the composite wallboard 1 is extruded by the pressing block 105 to move to the side close to the ground 404, the pull rod 201 moves to the side close to the ground 404 to drive the top block 106 to be pressed on the conductive sheet 107 of the composite wallboard 1, at the same time, the conductive plug 401 at the bottom end of the pull rod 201 moves downward to be inserted into the conductive jack 402 on the ground 404, the conductive contact block 403 on the pull rod 201 abuts against and is electrically connected with the conductive spring contact pin 3, and the conductive spring contact pin 3 and the top block 106 both abut against and are electrically connected with the conductive sheet 107 of the composite wallboard 1, therefore, after the conductive plug 401 is inserted into the conductive jack 402, the conductive sheet 107 in the composite wallboard 1 can automatically realize electrical connection with the ground wire, so as to realize rapid discharge of static electricity and induced charge on the composite wallboard 1.

By setting the compression spring 601 and the stop block 602, when the composite wall plate 1 is clamped into the first clamping groove 102 on the connecting column 101, the bottom end of the composite wall plate 1 abuts against the pressing block 105, the bottom end of the composite wall plate 1 applies downward pressure to the pressing block 105, thereby extruding the compression spring 601, the compression spring 601 applies downward elastic force to the stop block 602 after being extruded, thereby driving the pull rod 201 to move downward, the pull rod 201 drives the top block 106 to move, so that the top block 106 is pressed on the conductive sheet 107 of the composite wall plate 1, and under the action of the elastic force of the compression spring 601, the pressing block 105 always abuts against the bottom end of the composite wall plate 1, when the composite wall plate 1 is slightly dislocated relative to the connecting column 101, the spring elastic force can ensure that the pull rod 201 always drives the top block 106 to be pressed on the conductive sheet 107 of the composite wall plate 1, thereby improving the stability of the electrical connection between the composite wall plate 1 and the ground wire.
