Description

Technical Field

[0001] This invention relates to electrical connection technology, and more particularly to an integrated green electricity direct supply system that combines power generation, grid, load, and storage. Background Technology

[0002] The integrated power generation, grid, load, and energy storage system is a new power operation mode that plans power sources, grids, loads, and energy storage as a whole. Within this system, the primary power source is a network of clean energy, primarily wind and solar power, combined with energy storage. Backup power comes from the grid or other supplementary sources. The integrated system includes a wind-solar-energy storage network, substations, dedicated power lines for users, and multiple industrial users, with users connected to the grid through a common point. By integrating high-energy-consuming and high-emission enterprises with wind and solar power resources that cannot be connected to the grid, this system can promote low-carbon energy use by enterprises while increasing the local consumption rate of wind and solar power. The implementation of this integrated system requires the convergence of power from multiple regions via cables for unified control. During the cable convergence connection, the stability of the power supply and the progress of the power supply operation must be ensured. Summary of the Invention

The mounting base is disposed on the conductive block, and the cover plate is hinged to the mounting base via a hinge rod. The elastic element is disposed on the hinge rod. A conductive terminal extends through the mounting base to the middle of the mounting base. The first and second retaining elements are disposed in the middle of the mounting base, and a spring is provided between the first and second retaining elements. The first and second retaining elements are respectively installed in conjunction with different conductive terminals. The conductive terminals limit the external force applied by the spring to the first and second retaining elements. A retaining rod that cooperates with the first and second retaining elements is provided on the bottom surface of the cover plate. and an electrical connection terminal connected to the conductive base, wherein the electrical connection terminal is provided with a conductive element. The electrical connection terminal is located in the middle of the mounting base and is electrically connected to the conductive terminal. Pressing the cover plate applies pressure to the elastic element, causing the cover plate to drive the retaining rod to push the first retaining member and the second retaining member to compress the spring, and causing the lower end of the retaining rod to pass over the first retaining member and the second retaining member.

[0005] In this invention, the mounting base consists of a housing and a partition plate. The partition plate divides the interior of the housing into an upper mounting area and a lower mounting area. The conductive terminal is disposed in the lower mounting area, and the cover plate, elastic element, spring, first retaining element and second retaining element are disposed in the upper mounting area.

[0006] In this invention, the partition plate has a first through hole in the middle that mates with a conductive terminal, and the outer shell has a hinge hole that mates with a hinge rod and a movable hole that mates with a first retainer and a second retainer.

[0007] In this invention, the lower end of the retaining rod is provided with a retaining end, and the retaining end is provided with a guide slope and a blocking surface.

[0008] In this invention, the first retainer is composed of a first sliding post and a first sliding plate, and the second retainer is composed of a second sliding post and a second sliding plate, with the first sliding plate located at the upper end of the second sliding plate.

[0009] In this invention, the first sliding plate and the second sliding plate are respectively provided with retaining holes. The retaining holes are composed of a first arc region and a second arc region. The inner diameter of the first arc region is larger than the inner diameter of the second arc region. The inner diameter of the second arc region cooperates with the retaining rod. The maximum diameter of the retaining end is smaller than the inner diameter of the first arc region.

[0010] In this invention, the first sliding plate and the second sliding plate are respectively provided with sliding blocks. One side of the sliding block is provided with a positioning post and the other side is provided with an insertion plate. The positioning post is located in the middle of the spring. The conductive terminal is provided with an insertion groove that cooperates with the insertion plate.

[0011] In this invention, the electrical connection terminal is composed of a wrapping part and an electrical connection plate. The electrical connection plate is provided with a second through hole and symmetrically arranged third through holes. The second through hole cooperates with the retaining rod, and the third through hole cooperates with the conductive terminal for installation.

[0012] In this invention, the elastic element is composed of a transverse segment and symmetrically arranged first arc segment, connecting segment, spiral segment, inclined segment, second arc segment and vertical segment. The hinge rod is located in the middle of the spiral segment, and the transverse segment is in contact with the bottom surface of the cover plate.

[0013] In this invention, when the elastic element is in its natural state, the connecting section is kept in a vertical position; when the elastic element is subjected to pressure from the cover plate, the connecting section is kept in a horizontal position.

[0014] The integrated source-grid-load-storage green electricity direct supply system of this invention has the following beneficial effects: This integrated source-grid-load-storage green electricity direct supply system achieves electrical connection between multiple conductive components and conductive bases through conductive components, centrally aggregating power supply from different areas of the source-grid-load-storage system, thus realizing integrated power supply from the source-grid-load-storage system. During installation, the conductive components only require the first and second retaining members to cooperate with the conductive terminals of the conductive base. Furthermore, when connecting electrical connection terminals to conductive terminals, the position of the electrical connection terminals can be restricted by the retaining rod on the cover plate cooperating with the first and second retaining members. Installation and disassembly are achieved by pressing, which not only simplifies the electrical connection steps but also avoids unstable power transmission caused by loose bolts, thus accelerating the construction progress of the integrated source-grid-load-storage power supply system.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] like Figures 1 to 12 As shown, this integrated source-grid-load-storage green electricity direct supply system of the present invention includes a conductive base 1, a conductive component 2, and electrical connection terminals 3. The conductive component 2 is disposed on the conductive base 1, and the electrical connection terminals 3 are mounted on the conductive base 1 through the conductive component 2, maintaining multiple electrical connection terminals 3 electrically connected to the conductive base 1, and converging power from different areas through multiple cables. The conductive component 41 in this application can be a cable.

[0019] The conductive base 1 is provided with multiple conductive blocks 4, and each conductive block 4 is provided with symmetrically arranged conductive terminals 5. The conductive terminals 5 are provided with insertion slots 6, thereby restricting the positions of the first retaining member 7 and the second retaining member 8, allowing the first retaining member 7 and the second retaining member 8 to slide towards or away from each other. The conductive terminals 5 also restrict the spring 9 from pushing the first retaining member 7 and the second retaining member 8, preventing excessive movement of the first retaining member 7 and the second retaining member 8. Simultaneously, the first retaining member 7 and the second retaining member 8 restrict the position of the mounting base 10. Since the first retaining member 7 and the second retaining member 8 are located within the upper mounting area 11 of the mounting base 10, and the conductive terminals 5 pass through the partition 12 into the upper mounting area 11, while the first retaining member 7 and the second retaining member 8 are restricted by the spring 9 in the middle of the conductive terminals 5, the mounting base 10 is fixed to the conductive blocks 4, achieving installation without the need for other component structures to restrict the position of the mounting base 10.

[0020] The conductive component 2 is mounted on the conductive block 4. The conductive component 2 includes a mounting base 10, a cover plate 13, an elastic element 14, a first retaining element 7, and a second retaining element 8. The mounting base 10 is mounted on the conductive block 4. The cover plate 13 is hinged to the mounting base 10 via a hinge rod 15. The elastic element 14 is mounted on the hinge rod 15. When the cover plate 13 rotates, it can apply pressure to the elastic element 14, causing it to deform under pressure and maintain the elastic potential energy of the elastic element 14. When the first retaining element 7 and the second retaining element 8 are pressed, the retaining end 16 can be released from the restriction of the first retaining element 7 and the second retaining element 8. Under the elastic potential energy stored in the elastic element 14, the cover plate 13 is pushed to rotate, opening the upper mounting area 11.

[0021] The conductive terminal 5 extends through the mounting base 10 to the middle of the mounting base 10. The first retainer 7 and the second retainer 8 are disposed in the middle of the mounting base 10. A spring 9 is provided between the first retainer 7 and the second retainer 8. The spring 9 installed between the first retainer 7 and the second retainer 8 is in a slightly compressed state, so that the first retainer 7 and the second retainer 8 are forcefully installed in the upper mounting area 11.

[0022] The first retainer 7 and the second retainer 8 are respectively installed in conjunction with different conductive terminals 5. The conductive terminals 5 limit the external force applied to the first retainer 7 and the second retainer 8 by the spring 9. The bottom surface of the cover plate 13 is provided with a retaining rod 29 that cooperates with the first retainer 7 and the second retainer 8.

[0023] The mounting base 10 consists of a housing 17 and a partition 12. The partition 12 divides the interior of the housing 17 into an upper mounting area 11 and a lower mounting area 18. The conductive terminal 5 is disposed in the lower mounting area 18, and the cover plate 13, the elastic element 14, the spring 9, the first retaining element 7 and the second retaining element 8 are disposed in the upper mounting area 11.

[0024] The mounting base 10 is also provided with a first clearance opening 19 and a second clearance opening 20. The first clearance opening 19 is used to avoid the cover plate 13, while the second clearance opening 20 is used to avoid the electrical connection terminal 3. The height of the second clearance opening 20 matches the height of the sliding block 21, so that the electrical connection plate 22 is supported by the sliding block 21 and the second clearance opening 20.

[0025] A first through hole 23 is formed in the middle of the partition 12 to cooperate with the conductive terminal 5. The outer shell 17 is provided with a hinge hole 24 to cooperate with the hinge rod 15 and a movable hole 25 to cooperate with the first retainer 7 and the second retainer 8.

[0026] The lower end of the cover plate 13 is provided with a hinge block 26, and the center of the hinge block 26 is provided with a hinge hole 24 that mates with the hinge rod 15. The lower end of the cover plate 13 is also provided with a pressure plate 27, which is located within the second clearance opening 20. At the same time, an arc-shaped surface 28 is formed on one side of the cover plate 13 to facilitate the rotation of the cover plate 13.

[0027] The lower end of the retaining rod 29 is provided with a retaining end 16, on which a guide slope 30 and a blocking surface 31 are provided. The guide slope 30 pushes the first retaining member 7 and the second retaining member 8, causing the first retaining member 7 and the second retaining member 8 to move closer to each other, thereby compressing the spring 9.

[0028] The first retaining member 7 consists of a first sliding post 32 and a first sliding plate 33, and the second retaining member 8 consists of a second sliding post 34 and a second sliding plate 35, with the first sliding plate 33 located at the upper end of the second sliding plate 35. The first retaining member 7 and the second retaining member 8 have the same structure, but the heights of the first sliding plate 33 and the second sliding plate 35 are different.

[0029] The first sliding plate 33 and the second sliding plate 35 are respectively provided with retaining holes 36. The retaining hole 36 is composed of a first arc region 37 and a second arc region 38. The inner diameter of the first arc region 37 is larger than the inner diameter of the second arc region 38. The inner diameter of the second arc region 38 is matched with the retaining rod 29. The maximum diameter of the retaining end 16 is smaller than the inner diameter of the first arc region 37.

[0030] When the second arc region 38 and the second arc region 38 are engaged, that is, when the spring 9 is not pushed and compressed by the first retainer 7 and the second retainer 8, the second arc region 38 and the second arc region 38 engage to form a complete circle, and the inner diameter of the complete circle matches the diameter of the retaining rod 29. However, when the first arc region 37 and the second arc region 38 engage to form a complete circle, the inner diameter of the formed complete circle is larger than the diameter of the retaining rod 29, and also larger than the maximum diameter of the retaining end 16.

[0031] Sliding blocks 21 are provided on the first sliding plate 33 and the second sliding plate 35 respectively. A positioning post 39 is provided on one side of the sliding block 21 and an insertion plate 40 is provided on the other side. The positioning post 39 is located in the middle of the spring 9. The conductive terminal 5 is provided with an insertion groove 6 that cooperates with the insertion plate 40.

[0032] The lower end of the first sliding plate 33 forms a first sliding surface 54, and the upper end of the second sliding plate 35 forms a second sliding surface 55.

[0033] The insertion slot 6 and the insertion plate 40 cooperate to restrict the positions of the first retainer 7 and the second retainer 8, and also restrict the position of the mounting base 10.

[0034] Electrical connection terminal 3 is connected to conductive base 1. Electrical connection terminal 3 is provided with conductive element 41, which consists of contact end 42 and conductive rod 43. Insulating layer can be wrapped around conductive rod 43. Electrical connection terminal 3 consists of wrapping part 44 and electrical connection plate 22. A wrapping area 56 is formed in the middle of the wrapping part 44, and contact end 42 is disposed within the wrapping area 56. Electrical connection plate 22 is provided with a second through hole 45 and symmetrically arranged third through holes 46. The second through hole 45 cooperates with retaining rod 29, and the third through hole 46 cooperates with conductive terminal 5 for installation. The wrapping part 44 is used to wrap the contact end 42 on conductive element 41, thereby fixing electrical connection terminal 3 to conductive element 41.

[0035] The mounting base 10, cover plate 13, first retainer 7 and second retainer 8 are made of insulating material.

[0036] The elastic element 14 is composed of a transverse section 47 and symmetrically arranged first arc-shaped section 48, connecting section 49, spiral section 50, inclined section 51, second arc-shaped section 52 and vertical section 53. The hinge rod 15 is located in the middle of the spiral section 50, and the transverse section 47 is in contact with the bottom surface of the cover plate 13.

[0037] When the elastic element 14 is in its natural state, it keeps the connecting section 49 in a vertical position. When the elastic element 14 is pressed by the cover plate 13, it keeps the connecting section 49 in a horizontal position.

[0038] like Figure 12 The inclined section 51 on the elastic element 14 shown can limit the rotation angle of the cover plate 13. That is, the cover plate 13 is pushed to rotate by the connecting section 49 with elastic potential energy, keeping the upper mounting area 11 open. At this time, the electrical connection plate 22 is no longer restricted by the retaining rod 29 and the cover plate 13 and can be removed.

[0039] When installing the electrical connection terminal 3, the electrical connection terminal 3 is positioned in the middle of the mounting base 10 and is electrically connected to the conductive terminal 5. When the cover plate 13 is pressed, the cover plate 13 is pushed, and pressure is applied to the elastic member 14 through the cover plate 13, causing the cover plate 13 to drive the retaining rod 29 to push the first retaining member 7 and the second retaining member 8 to compress the spring 9. The first arc region 37 and the first arc region 37 form a complete circle, and the retaining end 16 at the lower end of the retaining rod 29 passes over the first retaining member 7 and the second retaining member 8, reaching the lower end of the first retaining member 7 and the second retaining member 8, thereby restricting the position of the electrical connection terminal 3.

[0040] When removing the electrical connection terminal 3, pressing the first retaining member 7 and the second retaining member 8 will push the cover plate 13 under the action of the elastic member 14 with elastic potential energy, keeping the cover plate 13 open. The retaining rod 29 will then disengage from the limiting positions of the first retaining member 7 and the second retaining member 8, allowing the electrical connection plate 22 to be removed from the conductive terminal 5. This facilitates the construction of an integrated power supply system for power generation, grid, load, and storage, and accelerates the construction progress.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
