Composite high strength material substation structure

Abstract

This utility model provides a substation frame made of composite high-strength material, relating to the field of substation frame technology, including a foundation, a support frame, and crossbeams. The support frame includes two sets of side braces and a reinforcing beam connecting the two sets of side braces. This utility model uses the two sets of side braces to jointly support the crossbeams, resulting in a larger effective support area at the bottom of the crossbeams. Furthermore, the two sets of side braces are interconnected by the reinforcing beam, improving the overall integrity of the structure. This prevents the two sets of side braces from tilting relative to each other under lateral loads, thus avoiding overall structural deformation. In addition, since the support frame and crossbeams are made of carbon fiber composite material, the strength of the substation frame is increased while its self-weight is reduced, thereby reducing the magnitude of settlement and further improving the stability of the structure. This makes the substation frame less prone to deformation under lateral loads and settlement caused by its own weight.

Description

Technical Field

[0001] This utility model relates to the field of substation structure technology, and in particular to a substation structure made of composite high-strength material. Background Technology

[0002] A substation frame refers to the structure used to support the incoming and outgoing lines and internal conductors within a substation; it is a crucial component of a substation.

[0003] The existing substation frame is supported by two sets of struts supporting the upper beam. The struts are only supported by the top beam, resulting in poor overall structure integrity. The struts are prone to tilting under large lateral wind loads, causing overall structural deformation. In addition, the existing substation frame is composed of steel pipes and structural steel components, resulting in a large overall self-weight. Over time, it is prone to significant settlement, leading to overall structural deformation and affecting structural stability. Utility Model Content

[0004] To address the technical problems of existing substation frames where the supports rely solely on the top beams for mutual support, resulting in poor overall structural integrity, and where the existing substation frames are composed of steel pipes and structural steel components, leading to a large overall self-weight and a tendency for significant settlement over time, this utility model provides a composite high-strength material substation frame.

[0005] The technical solution provided by this utility model embodiment is as follows:

[0006] This utility model provides a composite high-strength material substation frame, characterized in that it includes: a foundation, a support frame, and crossbeams;

[0007] The support frame includes two sets of side braces and a reinforcing beam connecting the two sets of side braces;

[0008] The side bracing includes two sets of support rods arranged in a figure-eight shape, a connecting beam connected in the middle of the two sets of support rods, and a mounting plate connected to the top of the two sets of support rods.

[0009] The reinforcing beam includes a set of horizontal bars and two sets of vertical bars connected to the bottom ends of the horizontal bars on both sides;

[0010] Flange rings are provided at the bottom of the support rod and the longitudinal rod, and flange rings are also provided on the connecting beam and at both ends of the cross rod;

[0011] Both the support frame and the crossbeam are made of carbon fiber composite material.

[0012] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0013] In this invention, two sets of side braces jointly support the crossbeam, resulting in a larger effective support area at the bottom of the crossbeam. Furthermore, the two sets of side braces are interconnected by reinforcing beams, improving the overall integrity of the structure. This prevents the two sets of side braces from tilting relative to each other due to lateral loads, thus avoiding overall deformation of the structure. In addition, since the support frame and crossbeam are made of carbon fiber composite material, the strength of the substation frame is improved while reducing its self-weight, thereby reducing the magnitude of settlement and further improving the stability of the structure. This makes the substation frame less prone to deformation under the settlement caused by lateral loads and self-weight. Attached Figure Description

[0028] like Figures 1 to 6 As shown, an embodiment of this utility model provides a substation frame made of composite high-strength material, including: a foundation 1, a support frame 2, and a crossbeam 3;

[0029] The support frame 2 includes two sets of side braces 21 and a reinforcing beam 22 connecting the two sets of side braces 21;

[0030] The side brace 21 includes two sets of support rods 21A arranged in a figure-eight shape, a connecting beam 21B connected in the middle of the two sets of support rods 21A, and a mounting plate 21C connected to the top of the two sets of support rods 21A.

[0031] The reinforcing beam 22 includes a set of horizontal bars 22A and two sets of vertical bars 22B connected to the bottom ends of the horizontal bars 22A.

[0032] Flange rings are provided at the bottom of the support rod 21A and the longitudinal rod 22B, and flange rings are also provided on the connecting beam 21B and at both ends of the cross rod 22A.

[0033] Both the support frame 2 and the crossbeam 3 are made of carbon fiber composite material.

[0034] It should be noted that after the foundation 1 is formed, the two sets of side supports 21 are hoisted onto the foundation 1, and the anchor bolts pre-installed on the foundation 1 are inserted into the flange rings at the bottom of the support rod 21A. At this time, the nuts are screwed onto the anchor bolts to fix the two sets of side supports 21 on both sides of the foundation 1. Then, the reinforcing beam 22 is hoisted between the two sets of side supports 21, so that the anchor bolts pre-installed on the foundation 1 are aligned and inserted into the flange rings at the bottom of the longitudinal rod 22B, and the flange rings at both ends of the transverse rod 22A are aligned with the flange rings on the connecting beam 21B. At this time, the bottom of the longitudinal rod 22B can be fixedly connected to the foundation 1, and the two ends of the transverse rod 22A are fixedly connected to the connecting beam 21B, so that the reinforcing beam 22 provides transverse support between the two sets of side supports 21. Finally, the transverse beam 3 is hoisted onto the top of the two sets of support frames 2 and secured with bolts. By fixing both ends of the crossbeam 3 to the mounting plate 21C, the substation frame installation is completed. The two sets of side braces 21 jointly support the crossbeam 3, resulting in a large effective support area at the bottom of the crossbeam 3. Furthermore, the two sets of side braces 21 are connected to each other by the reinforcing beam 22, which improves the overall integrity of the structure and prevents the two sets of side braces 21 from tilting relative to each other due to lateral loads, thereby avoiding overall deformation of the structure. In addition, since the support frame 2 and the crossbeam 3 are made of carbon fiber composite material, the density of carbon fiber composite material is only 1 / 4 that of steel, while its tensile strength is 5 times that of steel. Therefore, while improving the structural strength of the substation, it also reduces the self-weight of the structure, thereby reducing the magnitude of settlement and further ensuring the stability of the structure.

[0035] Furthermore, the crossbeam 3 includes three sets of beam frames 31 and reinforcing rods 32 connecting two adjacent sets of beam frames 31. The beam frames 31 and reinforcing rods 32 form a triangular grid space structure. When the cable is hung at the bottom of the crossbeam 3, the crossbeam 3 of the grid space structure can evenly distribute the load it receives, has good mechanical properties, and avoids the crossbeam 3 from deforming under load.

[0036] Furthermore, both the support frame 2 and the crossbeam 3 are coated with epoxy resin. The epoxy resin coating has good mechanical strength and corrosion resistance, which effectively protects the outer surfaces of the support frame 2 and the crossbeam 3 and improves the service life of the structure.

[0037] Furthermore, the foundation 1 is an I-shaped structure. The I-shaped foundation 1 can jointly provide support and fixation for the bottom of the support rods 21A and the longitudinal rods 22B, ensuring the integrity of the foundation 1 itself while saving the volume of concrete and avoiding uneven settlement between the two sets of support rods 21A and longitudinal rods 22B.

[0038] Furthermore, the cross-section of the support rod 21A is circular, and an inner support plate is provided inside. Since the support rod 21A directly bears the longitudinal load of the upper crossbeam 3, it will be subjected to a large bending moment stress. The inner support plate provides support force in multiple directions to the support rod 21A from the inside, thereby strengthening the overall bending resistance of the support rod 21A and preventing the support rod 21A from deforming and being damaged under a large bending moment stress.

[0039] Furthermore, a ladder 23 is fixedly connected to one side of the side support 21 via several connectors. A pedestrian walkway 33 is fixedly connected inside the crossbeam 3. A protective net (not shown in the attached drawings) is installed on the outside of the ladder 23. Guardrails (not shown in the attached drawings) are installed on both sides of the pedestrian walkway 33. The ladder 23 allows workers to climb onto the crossbeam 3, and the pedestrian walkway 33 allows workers to walk along the inside of the crossbeam 3, thereby facilitating maintenance work on the cables hanging at the bottom of the crossbeam 3. Several sets of lighting lamps 34 are installed at the top of the crossbeam 3. The lighting lamps 34 are located directly above the pedestrian walkway 33. The lighting lamps 34 can provide illumination for the pedestrian walkway 33 at night, allowing people to see the surroundings of the pedestrian walkway 33 when maintaining cables, thus improving safety.

[0040] Furthermore, a wind speed sensor 35 is installed at the top of the crossbeam 3. The wind speed sensor 35 is connected to a remote monitoring and alarm system. The wind speed sensor 35 senses the wind speed and converts it into an electrical signal. Then, the wind speed value is obtained through circuit processing and calculation. The value is then sent to the monitoring and alarm system through wireless communication technology. The alarm system determines whether to trigger an alarm based on a preset threshold. This can be used to remotely monitor the wind speed around the power transmission line and prevent line tripping and other faults caused by high wind speeds.

[0041] Furthermore, a lightning rod 36 is installed at the top of the crossbeam 3. The lightning rod 36 is fixedly installed at the top of the crossbeam 3 by an insulating base. The conductor of the lightning rod 36 is connected to the ground downwards. The lightning rod 36 can introduce and disperse lightning into the surrounding ground, preventing lightning from being directly conducted to the crossbeam 3 and causing an accident.

[0042] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0043] In this invention, the crossbeam 3 is supported by two sets of side braces 21, resulting in a larger effective support area at the bottom of the crossbeam 3. The two sets of side braces 21 are connected to each other by a reinforcing beam 22, which improves the overall integrity of the structure. This prevents the two sets of side braces 21 from tilting relative to each other on the inside and outside sides due to lateral loads, thus avoiding overall deformation of the structure. In addition, since the support frame 2 and the crossbeam 3 are made of carbon fiber composite material, the strength of the substation frame is improved while the self-weight of the structure is reduced, thereby reducing the magnitude of settlement and further improving the stability of the structure. This makes the substation frame less prone to deformation under the settlement caused by lateral loads and self-weight.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
