Description

Technical Field

[0001] This application relates to the field of bottle-making machine production technology, and in particular to a conductive polymer-based composite grounding device. Background Technology

[0002] Grounding devices are important components in electrical systems used to achieve electrical connection between equipment and the earth. They mainly consist of two parts: the grounding electrode, which is a metal conductor directly buried in the ground and in contact with the earth, such as round steel, angle steel, flat steel, steel pipe, etc. It can be artificially installed or can be a naturally existing metal component such as the foundation of a building.

[0003] Regarding the aforementioned technologies, the inventors believe that existing grounding devices using metal conductors are susceptible to corrosion after prolonged use due to external environmental factors such as rainwater, which affects the lifespan of the metal conductors. Utility Model Content

[0004] In order to improve the existing grounding devices using metal conductors, which are prone to corrosion after long-term use and thus affect the service life of the metal conductors, this application provides a conductive polymer-based composite grounding device.

[0005] The conductive polymer-based composite grounding device provided in this application adopts the following technical solution:

[0006] A conductive polymer-based composite grounding device includes: a buried box, wherein the buried box is buried below ground level;

[0007] The system includes a grounding electrode, which is disposed inside the underground box. The grounding electrode comprises a conductive polymer shell and a composite metal core disposed inside the conductive polymer shell.

[0008] Wherein: the conductive polymer shell is a polymer conductive structure with a continuous conductive path, and its outer layer has a corrosion-resistant protective structure to reduce the erosion of the internal composite metal core by external moisture and corrosive media.

[0009] The device includes a drive assembly for driving a grounding electrode into the ground. The drive assembly includes a sliding disc that is slidably disposed on the inner wall of the underground box, and the grounding electrode is fixed on the lower surface of the sliding disc.

[0010] Includes a threaded post (302) rotatably disposed on the bottom wall of the underground box and extending to the upper surface of the underground box, wherein a rotating disk is fixedly disposed at the top of the threaded post, and a crank is rotatably disposed on the upper surface of the rotating disk;

[0011] Wherein: the upper surface of the sliding disk is provided with a threaded hole that is threadedly connected to the outer surface of the threaded column;

[0012] The lower surface of the underground box has a first through hole for the grounding electrode to slide.

[0013] Optionally, the inner top wall and inner bottom wall of the underground box are fixed with two symmetrical limiting rods, and the upper surface of the sliding plate is provided with a sliding hole that is slidably connected to the outer surface of the two limiting rods.

[0014] By adopting the above technical solution and setting a limit rod, the stability of the sliding disk when sliding up and down is effectively guaranteed.

[0015] Optionally, the lower surface of the sliding disk is provided with a reinforcing component, which includes five ground cones fixed on the lower surface of the sliding disk, and the five ground cones and the grounding body are arranged in a circumferential array on the lower surface of the sliding disk. The lower surface of the buried box is provided with five second through holes for the five ground cones to slide.

[0016] By adopting the above technical solution and setting up ground cones, five ground cones can be simultaneously inserted into the ground as the sliding disc moves downward, thus improving the firmness of the grounding.

[0017] Optionally, the outer surface of the ground cone is symmetrically provided with two sets of sliding cavities, and a sealing piston plate is slidably provided on the inner wall of the sliding cavity. A barb block is fixed on the surface of the sealing piston plate, and a return spring is fixed on the surface of the sealing piston plate. The other end of the return spring is fixedly connected to the inner wall of the sliding cavity.

[0018] By adopting the above technical solution and setting up barbed blocks, the barbed blocks can be automatically extended after the ground cone is inserted into the ground, further improving the grounding stability.

[0019] Optionally, the ground cone has a cylindrical cavity inside, and the inner bottom wall of the cylindrical cavity has an air-filling channel, and the inner wall of the air-filling channel has an air-filling hole that communicates with the sliding cavity.

[0020] By adopting the above technical solution, and by setting up an inflation channel and an inflation hole, it is convenient to inflate the interior of the sliding cavity through the inflation hole, thereby facilitating the movement of the barb block.

[0021] Optionally, the reinforcement assembly further includes an inflatable airbag ring fixed to the lower surface of the sliding disk, and the inner top wall of the inflatable airbag ring is provided with an inflation tube extending into the cylindrical cavity.

[0022] By adopting the above technical solution and setting an inflatable airbag ring, the inflatable airbag ring can be squeezed during the downward movement of the sliding disc.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application, by setting up a grounding electrode, enables the grounding device to form a continuous conductive path during actual grounding by using conductive polymers such as polyaniline and polyacetylene as the matrix, and forming a columnar conductive polymer shell by adding inorganic fillers such as titanium dioxide and alumina. This effectively enhances the mechanical strength and corrosion resistance of the grounding electrode. At the same time, the built-in composite metal core serves as a supporting structure, improving the release of large currents. In the composite system, the conductive phase and the reinforcing phase form a three-dimensional conductive network, ensuring stable current conduction.

[0025] 2. This application sets up a driving component so that when the grounding device is actually grounded, the buried box is first placed into a pre-dug cylindrical pit, and then the rotating disc is turned by a crank. The rotation of the rotating disc drives the threaded column to rotate, and the rotation of the threaded column drives the sliding disc to move downward, thereby driving the grounding body to automatically insert into the ground, thus achieving the purpose of convenient grounding.

[0026] 3. By setting up reinforcement components, this application can drive five ground cones to insert into the ground during the downward movement of the sliding disc, effectively ensuring the stability after grounding. At the same time, when the sliding disc descends to a certain extent, it continues to descend, which can compress the inflatable airbag ring. This allows the air inside the inflatable airbag ring to enter the cylindrical cavity through the inflation pipe, and then enter the sliding cavity through the inflation channel and inflation hole. This compresses the sealing piston plate outward, thereby moving the hook block out of the sliding cavity and hooking it with the underground soil layer, thus further improving the stability and firmness after grounding.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a conductive polymer-based composite grounding device. (See attached image.) Figures 1 to 4 A conductive polymer-based composite grounding device includes: a buried box 100, which is buried below the ground. A grounding body 200 is provided inside the buried box 100. The grounding body 200 includes a conductive polymer shell 201 and a composite metal core 202 disposed inside the conductive polymer shell 201.

[0034] Reference Figure 3 In a preferred embodiment, the conductive polymer shell 201 is a columnar shell formed by adding inorganic fillers such as titanium dioxide and alumina to form a continuous conductive path using conductive polymer materials such as polyaniline and polyacetylene as the matrix.

[0035] Specifically, by using conductive polymer materials such as polyaniline and polyacetylene as the matrix to form a continuous conductive path, and by adding inorganic fillers such as titanium dioxide and alumina to form a columnar shell, the mechanical strength and corrosion resistance of the grounding electrode 200 are effectively enhanced.

[0036] In this application, by setting up a grounding electrode 200, the grounding device forms a continuous conductive path with conductive polymers such as polyaniline and polyacetylene as the matrix during actual grounding. The addition of inorganic fillers such as titanium dioxide and alumina forms a columnar conductive polymer shell 201, which can effectively enhance the mechanical strength and corrosion resistance of the grounding electrode 200. At the same time, the built-in composite metal core 202 serves as a support structure to improve the release of large currents. In the composite system, the conductive phase and the reinforcing phase form a three-dimensional conductive network to ensure stable current conduction.

[0037] The driving assembly 300 is used to drive the grounding body 200 into the ground. The driving assembly 300 includes a sliding disk 301 that is slidably disposed on the inner wall of the underground box 100. The grounding body 200 is fixed on the lower surface of the sliding disk 301. The driving assembly 300 also includes a threaded post 302 that is rotatably disposed on the inner bottom wall of the underground box 100 and extends to the upper surface of the underground box 100. A rotating disk 303 is fixed at the top of the threaded post 302. A crank is rotatably disposed on the upper surface of the rotating disk 303. A threaded hole is opened on the upper surface of the sliding disk 301 that is threadedly connected to the outer surface of the threaded post 302. A first through hole is opened on the lower surface of the underground box 100 for the grounding body 200 to slide.

[0038] Reference Figure 3The inner top wall and inner bottom wall of the underground box 100 are fixed with two symmetrical limiting rods 304, and the upper surface of the sliding plate 301 is provided with a sliding hole that is slidably connected to the outer surface of the two limiting rods 304.

[0039] Specifically, by setting the limit rod 304, the stability of the sliding disk 301 when sliding up and down is effectively guaranteed.

[0040] In this application, by setting up a drive component 300, the grounding device first places the buried box 100 into a pre-dug cylindrical pit when it is actually grounded. Then, by turning the rotating disk 303 with a crank, the rotation of the rotating disk 303 drives the threaded column 302 to rotate. The rotation of the threaded column 302 drives the sliding disk 301 to move downward, thereby driving the grounding body 200 to automatically insert into the ground, thus achieving the purpose of convenient grounding.

[0041] Reference Figure 3 The lower surface of the sliding disk 301 is provided with a reinforcing component 400. The reinforcing component 400 includes five ground cones 401 fixed on the lower surface of the sliding disk 301. The five ground cones 401 and the grounding body 200 are arranged in a circumferential array on the lower surface of the sliding disk 301. The lower surface of the buried box 100 is provided with five second through holes for the five ground cones 401 to slide.

[0042] Specifically, by setting up ground cones 401, five ground cones 401 can be simultaneously inserted into the ground as the sliding disc 301 moves downward, thus improving the firmness of the grounding.

[0043] Reference Figure 3 and Figure 4 Two sets of sliding cavities are symmetrically opened on the outer surface of the ground cone 401, and a sealing piston plate 402 is slidably arranged on the inner wall of the sliding cavity. A barb block 403 is fixedly provided on the surface of the sealing piston plate 402, and a return spring 404 is fixedly provided on the surface of the sealing piston plate 402. The other end of the return spring 404 is fixedly connected to the inner wall of the sliding cavity.

[0044] Specifically, by setting up the barb block 403, the barb block 403 can be automatically extended after the ground cone 401 is inserted into the ground, further improving the grounding stability.

[0045] Reference Figure 3 and Figure 4 The ground cone 401 has a cylindrical cavity 405 inside, and the inner bottom wall of the cylindrical cavity 405 has an inflation channel 406. The inner wall of the inflation channel 406 has an inflation hole 407 that communicates with the sliding cavity.

[0046] Specifically, by setting up an inflation channel 406 and an inflation hole 407, it is convenient to inflate the interior of the sliding cavity through the inflation hole 407, thereby facilitating the movement of the barb block 403.

[0047] Reference Figure 3 and Figure 4 The reinforcement component 400 also includes an inflatable airbag ring 408 fixed on the lower surface of the sliding disk 301, and the inner top wall of the inflatable airbag ring 408 is provided with an inflation tube 409 extending into the cylindrical cavity 405.

[0048] Specifically, by setting an inflatable airbag ring 408, the inflatable airbag ring 408 can be squeezed during the downward movement of the sliding disc 301.

[0049] In this application, by setting up a reinforcement component 400, five ground cones 401 can be driven to insert into the ground during the downward movement of the sliding disc 301, effectively ensuring the stability after grounding. At the same time, when the sliding disc 301 descends to a certain extent, it continues to descend, which can compress the inflatable airbag ring 408, so that the air in the inflatable airbag ring 408 enters the cylindrical cavity 405 through the inflation pipe 409, and enters the sliding cavity through the inflation channel 406 and the inflation hole 407, which compresses the sealing piston plate 402 outward, thereby causing the barb block 403 to move out of the sliding cavity and hook onto the underground soil layer, thereby further improving the stability and firmness after grounding.

[0050] The implementation principle of the conductive polymer-based composite grounding device in this application embodiment is as follows: When the grounding device is actually grounded, the buried box 100 is first placed into the pre-dug cylindrical pit. Then, the rotating disk 303 is rotated by the crank handle. The rotation of the rotating disk 303 drives the threaded column 302 to rotate. The rotation of the threaded column 302 drives the sliding disk 301 to move downward, thereby driving the grounding body 200 to automatically insert into the ground, achieving the purpose of convenient grounding. Moreover, during the downward movement of the sliding disk 301, it can drive the five ground cones 401 to insert into the ground, effectively ensuring the stability after grounding. At the same time, when the sliding disk 301 descends to a certain extent, it continues to descend, which can compress the inflatable airbag ring 408. The air in the inflatable airbag ring 408 enters the cylindrical cavity 405 through the inflation pipe 409, and enters the sliding cavity through the inflation channel 406 and the inflation hole 407, squeezing the sealing piston plate 402 outward, thereby causing the barb block 403 to move out of the sliding cavity and hook onto the underground soil layer, thereby further improving the stability and firmness after grounding.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
