Description

Technical Field

[0001] This utility model belongs to the field of mounting bracket technology, specifically relating to a modular quick mounting bracket for substation secondary equipment, which is particularly suitable for the rapid positioning and installation of substation secondary equipment (such as relays, instruments, control modules, etc.) of different specifications. Background Technology

[0002] Secondary equipment in a substation refers to auxiliary equipment used in a substation to monitor, control, measure, protect, and regulate primary equipment (such as transformers, circuit breakers, disconnectors, and other equipment that directly participate in the production, transmission, and distribution of electrical energy). They do not directly handle high-voltage electrical energy, but rather are associated with the primary equipment through electrical or electronic signals to ensure the safe, stable, and efficient operation of the substation.

[0003] Substation secondary equipment mounting racks are supports used to install substation secondary equipment and accessories. According to structural type, they include frame-type mounting racks, cabinet-type mounting racks, and prefabricated mounting racks. Among them, prefabricated mounting racks adopt a modular design and are assembled from multiple prefabricated components. Prefabricated mounting racks have the advantages of convenient and quick installation. They can be quickly assembled on site, reducing installation time and workload, and also facilitating later maintenance and replacement.

[0004] However, existing prefabricated mounting racks are mostly designed with fixed dimensions and cannot be flexibly adjusted. When it is necessary to install secondary equipment of different specifications (such as differences in length, width, and thickness), it is necessary to replace the mounting rack with one of the corresponding dimensions. This results in poor versatility, increased equipment procurement costs, and frequent replacement of mounting racks will prolong on-site construction time and reduce installation efficiency.

[0005] To address the aforementioned issues, this utility model proposes a modular quick-installation frame for substation secondary equipment. Through an adjustable structure, it enables adaptation to secondary equipment of different specifications, while simultaneously ensuring installation stability and ease of operation. Utility Model Content

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1-4 The present invention provides the following technical solution: a modular quick installation frame for substation secondary equipment, including a support plate 1 for supporting the substation secondary equipment, and further including: side positioning plates 2 symmetrically fixed on both sides of the support plate 1, a flip plate 3 that can be flipped and connected to the side positioning plates 2, a pressure plate 4 that can be adjusted and connected to the free end of the flip plate 3, an adjustment component 5 for adjusting the height of the pressure plate 4, and a side clamping component 6 for clamping the substation secondary equipment from both sides.

[0041] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the adjustment component 5 includes: a first screw 51 fixed to the free end of the flip plate 3 and a first wing nut 52 installed on the protruding end of the first screw 51 by means of thread engagement, and the first screw 51 passes through the pressure plate 4. After adopting the above scheme, when using it, the substation secondary equipment to be installed is first placed on the support plate 1 to ensure that the equipment is in a suitable position between the two side positioning plates 2. The side positioning plates 2 can play a preliminary lateral limiting role for the equipment to prevent the equipment from shifting significantly to the left or right during the installation process.

[0042] Next, flip the flip plates 3 on both sides, so that the flip plates 3 rotate from the initial open state to the position covering the top of the secondary equipment. At this time, the pressure plate 4 connected to the free end of the flip plates 3 will be located above the equipment.

[0043] Since the first screw 51 passes through the pressure plate 4 and the first wing nut 52 is installed by threaded engagement, the height of the pressure plate 4 on the first screw 51 can be adjusted by rotating the first wing nut 52 using threaded transmission.

[0044] For example, when the first wing nut 52 is rotated clockwise, it will move downwards, pushing the pressure plate 4 closer to and pressing the top of the secondary equipment. Conversely, rotating it counterclockwise will loosen the pressure plate 4, making it easier to adjust the position of the pressure plate 4 to accommodate equipment of different heights. Thus, the pressure plate 4 can be used to longitudinally press and fix the equipment, preventing it from shaking up and down.

[0045] After longitudinal fixation is completed, the side clamping assembly 6 is used to apply clamping force to the substation secondary equipment from both sides to further enhance the lateral stability of the equipment and prevent the equipment from shifting left or right when it is running or subjected to external forces.

[0046] The initial positioning of the side positioning plate 2, the longitudinal pressing of the pressure plate 4 under the action of the adjustment component 5, and the lateral clamping of the side clamping component 6 work together to quickly and stably fix the substation secondary equipment on the mounting frame, achieving modular and rapid installation, which greatly improves installation efficiency and the stability of the equipment after installation.

[0047] Preferably, by Figure 1 As shown, in this embodiment, it also includes a first rubber pad 41 that is bonded and fixed to the bottom surface of the pressure plate 4. After adopting the above solution, when the pressure plate 4 is adjusted to press the top of the secondary equipment by adjusting the component 5, the first rubber pad 41 that is bonded and fixed to the bottom surface of the pressure plate 4 will first contact the top surface of the equipment.

[0048] As the first wing nut 52 is continuously tightened, the first rubber gasket 41 undergoes elastic deformation under the pressure of the pressure plate 4, and fits tightly against the surface of the top of the equipment.

[0049] On the one hand, it can increase the friction between the pressure plate 4 and the equipment, and with the locking force of the first wing nut 52, further improve the stability of longitudinal fixation and effectively prevent the equipment from slipping at the top under vibration. On the other hand, the first rubber pad 41 can buffer the rigid pressure of the pressure plate 4 on the equipment, and avoid scratches or deformation of the equipment shell caused by the pressure plate 4 directly contacting the equipment, thus protecting the surface of the equipment.

[0050] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the side clamping assembly 6 includes: a second screw 61 installed on the flip plate 3 by means of threaded engagement, a side clamping plate 62 fixed to the clamping end of the second screw 61, and a handle 63 fixed to the end of the second screw 61. With the above solution, when in use, after the pressure plate 4 has completed the longitudinal pressing of the secondary equipment, the operator can achieve the lateral clamping and fixing of the equipment through the side clamping assembly 6. At this time, the second screw 61 of the side clamping assembly 6 has been installed on the flip plate 3 by means of threaded engagement, and its clamping end is connected to the side clamping plate 62, and the end is provided with a handle 63 for easy operation.

[0051] The operator holds the handle 63 and rotates it clockwise. Since the second screw 61 is threadedly engaged with the flip plate 3, the second screw 61 will move along the thread direction towards the side closer to the secondary equipment during the rotation, thereby driving the side clamp 62 fixed at its clamping end to move towards the side of the equipment in sync.

[0052] As the handle 63 continues to rotate, the side clamp 62 gradually comes into contact with the side of the equipment. If the handle 63 continues to be rotated, the side clamp 62 will generate a continuously increasing clamping force on the side of the equipment.

[0053] When both sides of the side clamping assembly 6 are operated until the side clamping plate 62 is tightly attached to the side of the equipment and the appropriate clamping force is reached, stop rotating the handle 63. At this time, the side clamping plates 62 on both sides form a stable clamping force on the secondary equipment from the lateral direction. In conjunction with the initial limiting effect of the side positioning plate 2, it can effectively limit the displacement of the equipment in the lateral direction and prevent the equipment from swaying left and right due to vibration and other factors during operation.

[0054] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the side clamping assembly 6 further includes a second rubber pad 621 that is bonded and fixed to the clamping surface of the side clamping plate 62. With the above solution, when the substation secondary equipment is clamped laterally by the side clamping assembly 6, as the handle 63 rotates, the second screw 61 drives the side clamping plate 62 to move closer to the side of the equipment. At this time, the second rubber pad 621 that is bonded and fixed to the clamping surface of the side clamping plate 62 will first contact the side of the equipment.

[0055] As the handle 63 continues to rotate, the clamping force of the side clamp 62 on the equipment gradually increases. Under the action of the clamping force, the second rubber pad 621 undergoes elastic deformation. This deformation allows the second rubber pad 621 to fit more closely to the contour of the side of the equipment. Even if there are slight unevennesses on the side of the equipment, the elasticity of the rubber can fill the gaps, thereby increasing the contact area between the side clamp 62 and the equipment, improving the friction, further enhancing the stability of the lateral clamping, and effectively preventing the equipment from slipping when subjected to external forces or vibrations.

[0056] Meanwhile, the second rubber pad 621 also plays a role in buffering and protection, avoiding direct rigid contact between the side clamp 62 and the side of the equipment. During the clamping process, it can disperse the clamping force and prevent damage such as scratches and dents on the side of the equipment due to excessive local pressure. It can play a very good protective role, especially for secondary equipment with fragile outer shell materials.

[0057] In addition, when vibration occurs during equipment operation, the elasticity of the second rubber pad 621 can absorb some of the vibration energy, reduce the rigid collision between the equipment and the side clamp 62, reduce the impact of vibration on the equipment connection parts, help maintain the long-term stability of the equipment installation, and extend the service life of the equipment.

[0058] Optionally, by Figure 1 and Figure 4As shown, this embodiment also includes: a fixing screw 8 fixed to the side positioning plate 2, the fixing screw 8 passing through the flip plate 3 and a second wing nut 9 installed at the protruding end of the fixing screw 8 by thread engagement. With the above solution, when in use, the flip plate 3 can be flipped around the fixing screw 8 as the axis, the second wing nut 9 limits the flip plate 3 from the side, and the friction between the flip plate 3 and the side positioning plate 2 ensures the stability of the flip plate 3.

[0059] In addition, the position of the flip plate 3 can be finely adjusted by rotating the second wing nut 9, thereby adjusting the friction between the flip plate 3 and the side positioning plate 2.

[0060] Preferably, by Figure 1 As shown, this embodiment also includes a back positioning plate 7 fixed to the top surface of the support plate 1. The back positioning plate 7 is used to position the substation secondary equipment from the back. A lead wire hole 71 is provided on the back positioning plate 7. With the above solution, when the substation secondary equipment is placed on the support plate 1, the back positioning plate 7 will accurately position it from the back of the equipment. The operator only needs to place the back of the equipment against the surface of the back positioning plate 7 to quickly determine the installation position of the equipment in the front-back direction, avoiding the equipment from being affected by the front-back placement offset and affecting subsequent wiring and operation. This greatly reduces the time for adjusting the equipment position and improves the convenience and accuracy of installation.

[0061] Meanwhile, since the secondary equipment of the substation needs to be connected to the lines during operation, the lead wire holes 71 set on the back positioning plate 7 play a key role. When the back of the equipment is fixed to the back positioning plate 7, the cables on the back of the equipment can be orderly passed through the lead wire holes 71. This not only organizes and guides the cables, preventing them from getting tangled and affecting the heat dissipation of the equipment or causing safety hazards, but also prevents the cables from being squeezed and damaged by the equipment or mounting bracket, thus ensuring the safety and stability of the line connection.

[0062] Components not described in detail in this article are existing technologies.

[0063] The working principle and usage process of this utility model: When using the quick installation frame of this utility model, first place the substation secondary equipment to be installed on the support plate 1, and ensure that the equipment is in a suitable position between the two side positioning plates 2. The side positioning plates 2 can play a preliminary lateral limiting role for the equipment, preventing the equipment from shifting significantly to the left or right during the installation process. Then, place the back of the equipment against the surface of the back positioning plate 7 to determine the installation position of the equipment in the front-back direction.

[0064] Next, flip the flip plates 3 on both sides, so that the flip plates 3 rotate from the initial open state to the position covering the top of the secondary equipment. At this time, the pressure plate 4 connected to the free end of the flip plates 3 will be located above the equipment.

[0065] Since the first screw 51 passes through the pressure plate 4 and the first wing nut 52 is installed by thread engagement, the height of the pressure plate 4 on the first screw 51 can be adjusted by rotating the first wing nut 52 using thread transmission.

[0066] For example, when the first wing nut 52 is rotated clockwise, the first wing nut 52 will move downward, pushing the pressure plate 4 to gradually approach and press the top of the secondary equipment; conversely, rotating counterclockwise will loosen the pressure plate 4, making it easier to adjust the position of the pressure plate 4 to adapt to equipment of different heights, thereby achieving longitudinal pressing and fixing of the equipment through the pressure plate 4 to prevent the equipment from shaking up and down.

[0067] After longitudinal fixation is completed, the side clamping assembly 6 is used to apply clamping force to the substation secondary equipment from both sides to further enhance the lateral stability of the equipment and prevent the equipment from shifting to the left or right when it is running or subjected to external force. The operator holds the handle 63 and rotates it clockwise. Since the second screw 61 is threadedly engaged with the flip plate 3, the second screw 61 will move along the thread direction towards the side closer to the secondary equipment during rotation, thereby driving the side clamping plate 62 fixed at its clamping end to move towards the side of the equipment in sync. As the handle 63 continues to rotate, the side clamping plate 62 gradually contacts the side of the equipment. If the handle 63 is rotated further, the side clamping plate 62 will generate a continuously increasing clamping force on the side of the equipment. When both sides of the side clamping assembly 6 are operated until the side clamping plate 62 is tightly attached to the side of the equipment and the appropriate clamping force is reached, the rotation of the handle 63 is stopped.

[0068] The initial positioning of the side positioning plate 2, the longitudinal pressing of the pressure plate 4 under the action of the adjustment component 5, and the lateral clamping of the side clamping component 6 work together to quickly and securely fix the substation secondary equipment on the mounting frame, achieving modular and rapid installation. This greatly improves installation efficiency and the stability of the equipment after installation. It is also suitable for various specifications of secondary equipment, eliminating the need to customize mounting frames for different equipment and reducing equipment procurement and replacement costs.

[0069] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
