[0001] This utility model relates to the field of modular installation technology of electrical equipment, and in particular to a detachable fixed bracket for a 10kV line switch terminal repair device. Background Technology
[0002] A typical FTU consists of a plastic housing and a plastic base plate. Its internal space is generally fixed. The internal components, including circuit boards, power modules, and capacitor modules, need to be arranged in the internal space of the FTU's plastic housing using brackets. However, the current bracket construction does not meet the standards, resulting in uneven placement of components, unstable brackets, and easy deformation and damage.
[0003] To address the aforementioned issues, existing patent (CN216121350U) discloses an internal support device for an FTU. A fixing plate is fixedly connected to the main support, and the fixing plate has several mounting holes. Small supports and mounting brackets are provided on the inner wall of the main support. Both the small supports and mounting brackets are mounted on mounting slots using screws, and both have threaded holes. Mounting blocks are fixedly connected to both the main support and the fixing plate. The mounting blocks can fix large capacitor modules. The main support is mounted on a plastic panel via the mounting plate. The fixing plate can mount power modules. The small supports can be mounted on the main support via mounting slots, and their positions can be adjusted. DC boards and capacitor modules can be mounted on the small supports. This device can address issues such as uneven component placement, unstable support, and prevents the main support from easily deforming or being damaged due to excessive component pressure.
[0004] However, the existing technologies mentioned above cannot effectively attenuate high-frequency micro-amplitude vibrations, which may cause internal components of the module to loosen or be damaged; the accumulation of dust and liquid may affect the normal operation of the equipment, and the failure to meet high protection standards limits the application of the equipment in complex environments. Utility Model Content
[0005] The purpose of this utility model is to provide a detachable fixing bracket for a 10kV line switch terminal repair device, which aims to solve the technical problems in the prior art where the inability to effectively attenuate high-frequency micro-amplitude vibrations can cause loosening or damage to internal components of the module; the accumulation of dust and liquids may affect the normal operation of the equipment; and the failure to meet high protection standards limits the application of the equipment in complex environments.
[0006] To achieve the above objectives, this utility model employs a detachable fixing bracket for a 10kV line switch terminal repair device, comprising a base frame, mounting ears, a hand-tightening wing nut, a bearing plate, and a silicone shock-absorbing pad. The mounting ears are fixedly connected to the base frame and located on the outside of the base frame. The hand-tightening wing nut is detachably connected to the mounting ears and located on the outside of the mounting ears. The bearing plate is fixedly connected to the base frame and located inside the base frame. The silicone shock-absorbing pad is fixedly connected to the bearing plate and located above the module bearing plate.
[0007] The silicone shock-absorbing pad has staggered protrusions and V-shaped grooves. The staggered protrusions are fixedly connected to the silicone shock-absorbing pad and are located on the outside of the silicone shock absorber. The V-shaped grooves are fixedly connected to the silicone shock-absorbing pad and are located on the outside of the staggered protrusions.
[0008] The base frame has a slot and a longitudinal track. The slot has a U-shaped profile and runs through the base frame. The longitudinal track is fixedly connected to the base frame and is located below the slot.
[0009] The base frame also includes a fixing rod and an opening / closing door. The fixing rod is fixedly connected to the base frame and located below the silicone shock-absorbing pad. The opening / closing door is rotatably connected to the fixing rod and located outside the fixing rod.
[0010] The base frame also includes a lock cylinder and a transparent window. The lock cylinder is detachably connected to the base frame and is located on the outside of the opening and closing door. The transparent window is fixedly connected to the opening and closing door and is located on the outside of the opening and closing door.
[0011] The support plate has heat dissipation holes and a trapezoidal cross-section. The heat dissipation holes are in a rectangular matrix and penetrate the support plate. The inner wall of the heat dissipation holes is designed to be inclined to form the trapezoidal cross-section.
[0012] This utility model discloses a detachable fixing bracket for a 10kV line switch terminal repair device. In practical use, the mounting ears are used for mounting and fixing the base frame. The mounting ears are fixed by the matching hand-tightening wing nuts and the reserved bolts. The module is installed in the base frame, and the bearing plate supports the module. The staggered protrusions on the surface of the silicone shock-absorbing pad convert the vertical vibration energy of the module into protrusion deformation dissipation, which can attenuate 20%-30% of high-frequency micro-amplitude vibration. The V-shaped groove guides dust or liquid in the silicone shock-absorbing pad to slide off, avoiding accumulation. This effectively solves the problems of ineffective attenuation of high-frequency micro-amplitude vibration and the impact of dust and liquid accumulation on the normal operation of the equipment.

Detailed Implementation
[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0020] Please see Figures 1 to 4This utility model provides a detachable fixing bracket for a 10kV line switch terminal repair device, including a base frame 1, mounting ears 2, a hand-tightened wing nut 3, a support plate 4, and a silicone shock-absorbing pad 5. The mounting ears 2 are fixedly connected to the base frame 1 and located on the outside of the base frame 1. The hand-tightened wing nut 3 is detachably connected to the mounting ears 2 and located on the outside of the mounting ears 2. The support plate 4 is fixedly connected to the base frame 1 and located inside the base frame 1. The silicone shock-absorbing pad 5 is fixedly connected to the support plate 4 and located above the module support plate 4. The silicone shock-absorbing pad 5 has staggered protrusions 501 and V-shaped grooves 502. The staggered protrusions 501 are fixedly connected to the silicone shock-absorbing pad 5 and located on the outside of the silicone shock absorber. The V-shaped grooves 502 are fixedly connected to the silicone shock-absorbing pad 5 and located on the outside of the staggered protrusions 501.
[0021] In this embodiment, the mounting ear 2 is pre-set with bolt holes. The mounting ear 2 is used for mounting and fixing the base frame 1. The mounting ear 2 is fixed by the matching hand-tightening wing nut 3 and the reserved bolt. The module is installed in the base frame 1. The bearing plate 4 supports the module. The silicone shock-absorbing pad 5 is made of customized silicone composite material and is integrally molded by molding process. The shock-absorbing pad has staggered protrusions 501 on the upper and lower surfaces. Through the staggered protrusions 501 on the surface of the silicone shock-absorbing pad 5, the vertical vibration energy of the module is converted into protrusion deformation dissipation, which can attenuate 20%-30% of high-frequency micro-amplitude vibration. The V-shaped groove 502 guides the dust or liquid in the silicone shock-absorbing pad 5 to slide off, avoiding accumulation. This can effectively solve the problems of ineffective attenuation of high-frequency micro-amplitude vibration and the impact of dust and liquid accumulation on normal equipment operation.
[0022] Furthermore, the base frame 1 has a slot 101 and a longitudinal track 102. The slot 101 has a U-shaped profile and passes through the base frame 1. The longitudinal track 102 is fixedly connected to the base frame 1 and is located below the slot 101.
[0023] In this embodiment, the U-shaped groove 101 allows the operator to insert their index and middle fingers with one hand to grasp the upper sides of the module. The edges of the groove 101 are rounded, and the inner wall of the groove 101 is provided with the longitudinal track 102. The center line of the groove 101 is aligned with the guide rail of the module shell. When the module is pulled out, the direction of force is automatically corrected so that it can be fixed inside the base frame 1, increasing its stability and avoiding skewing and jamming.
[0024] Furthermore, the base frame 1 also has a fixing rod 103 and an opening / closing door 104. The fixing rod 103 is fixedly connected to the base frame 1 and is located below the silicone shock-absorbing pad 5. The opening / closing door 104 is rotatably connected to the fixing rod 103 and is located outside the fixing rod 103.
[0025] In this embodiment, the opening and closing door 104 rotates around the fixed rod 103, and opening the opening and closing door 104 facilitates the setting and maintenance of the module after installation.
[0026] Furthermore, the base frame 1 also has a lock cylinder 105 and a transparent window 106. The lock cylinder 105 is detachably connected to the base frame 1 and is located on the outside of the opening and closing door 104. The transparent window 106 is fixedly connected to the opening and closing door 104 and is located on the outside of the opening and closing door 104.
[0027] In this embodiment, the door 104 can be opened by using the inspection key in conjunction with the lock cylinder 105, thereby ensuring the security of the door 104 and facilitating the observation of the installation module through the transparent window 106.
[0028] Furthermore, the support plate 4 has heat dissipation holes 401 and a trapezoidal cross section 402. The heat dissipation holes 401 are in a rectangular matrix and penetrate the support plate 4. The inner wall of the heat dissipation holes 401 is designed to be inclined to form the trapezoidal cross section 402.
[0029] In this embodiment, the support plate 4 is provided with the heat dissipation holes 401 in a rectangular matrix shape. The heat dissipation holes 401 allow cold air to flow vertically upward from the bottom, forming a continuous through-flow air duct that directly covers the heat-generating area of the module, avoiding local heat retention and reducing the surface temperature of the module. If the FTU chassis is equipped with a cooling fan, the heat dissipation holes 401 can form a synergistic effect with the airflow direction of the fan, further improving the heat dissipation efficiency. At the same time, the inclined design of the inner wall of the heat dissipation holes 401 not only prevents dust from falling vertically into the bracket, but also improves the bending strength of the support plate 4 through the trapezoidal cross section 402.
[0030] The beneficial effects of this utility model are as follows: The mounting ear 2 is used for the installation and fixation of the base frame 1. The mounting ear 2 is fixed by the matching hand-tightening wing nut 3 and the reserved bolt, thereby realizing the quick installation of the base frame 1. The guide rail of the module shell is aligned with the longitudinal rail 102, so that the module can be stably aligned and installed in the base frame 1. The bearing plate 4 supports the module. The staggered protrusions 501 on the surface of the silicone shock-absorbing pad 5 convert the vertical vibration energy of the module into protrusion deformation dissipation, which can attenuate 20%-30% of the high frequency. With slight vibration, the V-shaped groove 502 guides dust or liquid in the silicone damping pad 5 to slide off from the trapezoidal section 402 of the heat dissipation hole 401, preventing accumulation. The heat dissipation hole 401 is used to improve the heat dissipation efficiency of the module, thereby enabling convenient and stable installation of the fixed bracket and facilitating one-handed gripping of the module, preventing the module from slipping during installation or operation, effectively avoiding local heat retention in the module, reducing the surface temperature of the module, and effectively attenuating 20%-30% of high-frequency slight vibration by setting the silicone damping pad 5, protecting the module from vibration damage and improving equipment reliability.
[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
