Description
Technical Field
[0001] This utility model relates to the technical field of reactive power compensation boxes, specifically a fixing structure for a reactive power compensation box. Background Technology
[0002] Reactive power compensation boxes are crucial devices in power systems for optimizing reactive power distribution. They primarily improve power factor, reduce line energy loss, and stabilize voltage levels by compensating for reactive power, thereby enhancing power quality and supply efficiency. They are commonly used in industrial parks, residential areas, substations, and distribution transformer areas, playing a significant role in energy conservation, emission reduction, and power stabilization within the power grid. Reactive power compensation boxes typically include key components such as capacitors, filters, and control modules. Depending on requirements, they can be categorized into low-voltage and high-voltage reactive power compensation boxes, and their operation is monitored and dynamically adjusted using automation technology.
[0003] Utility model patent CN214255317U discloses a compensation box structure for low-voltage reactive power compensation in transformer substations. The structure includes a device body with lead screws on both sides of its inner wall. Slider blocks are located on the outer sides of both ends of the lead screws. A clamp is located between the two sliders on the same side. Limiting rods are located on both sides of the inner wall of the clamp. A movable seat is located on the outer side of the limiting rod. A buffer rod is located on one side of the movable seat, a fixed seat is located on one side of the buffer rod, and a protective pad is located on one side of the fixed seat. This utility model, through the arrangement of lead screws and clamps, allows a servo motor to drive the two lead screws to rotate, thereby adjusting the distance between the two clamps. This enables the compensation box to adapt to installations at different sizes. Simultaneously, when the clamps clamp the installation area, the buffer rods support and cushion the protective pad, which in turn clamps and protects the installation area, making the installation and disassembly of the compensation box more convenient.
[0004] The existing technology described above, in practical use, uses a servo motor to drive two lead screws to rotate, thereby causing two clamps to move relative to each other to hold and fix the installation part, effectively achieving the fixed installation of the reactive power compensation box. However, this technology has the following shortcomings: First, since the servo motor is the power source, its operation requires additional electrical energy, further increasing the energy consumption of the equipment. Furthermore, installation and disassembly operations may not be possible during power outages or power failures. Second, the lead screws are exposed to the elements for extended periods, making them susceptible to contamination by dust and impurities, leading to the accumulation of impurities on the screw threads, affecting the smooth movement of the slider, and thus increasing the difficulty of disassembly and subsequent maintenance. Based on these issues, we propose a fixing structure for the reactive power compensation box to further improve installation convenience, stability, and durability. Utility Model Content
[0005] The purpose of this utility model is to provide a fixing structure for a reactive power compensation box to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A fixed structure for a reactive power compensation box includes a support column, which is generally an outdoor utility pole. The support column is detachably connected to the reactive power compensation box body via a quick-release assembly. The quick-release assembly is used to realize the quick installation and disassembly of the box body. The rear side of the reactive power compensation box body is provided with four T-shaped suspension blocks arranged in a matrix. The T-shaped suspension blocks are used for suspension and fixation and cooperate with the quick-release assembly to achieve positioning. The quick-release assembly includes two fixed horizontal plates arranged symmetrically at the top and bottom. Support blocks are provided on the front side of the two fixed horizontal plates near the left and right ends. The support blocks are used to support the T-shaped suspension blocks. The top of the support blocks is provided with a T-shaped groove that is adapted to the T-shaped suspension blocks. The T-shaped groove is used to guide the T-shaped suspension blocks to slide in and restrict their horizontal displacement. Positioning members are provided on the rear side of the two fixed horizontal plates near the left and right ends to fix the T-shaped suspension blocks in the T-shaped grooves. The positioning members are used to lock the T-shaped suspension blocks to prevent them from falling out of the T-shaped grooves. Two connecting blocks are provided on the rear side of each of the two fixed horizontal plates, which are arranged symmetrically from left to right. The two connecting blocks on the fixed horizontal plates are connected to a fixed clamp. The fixed clamp is connected to a movable clamp by bolts and nuts. The movable clamp is used to adapt to the support column of different sizes. The movable clamp and the fixed clamp are clamped and fixed to the outside of the support column. The clamp structure realizes a stable connection between the quick-release component and the support column.
[0007] Preferably, three connecting vertical plates are provided between the two fixed horizontal plates, which are arranged equidistantly from left to right. The connecting vertical plates are used to vertically connect the upper and lower fixed horizontal plates to enhance the structural strength. A reinforcing horizontal plate is provided between two adjacent connecting vertical plates to horizontally connect the adjacent connecting vertical plates to prevent the frame from deforming.
[0008] Preferably, the positioning component includes a circular housing fixedly connected to the rear side of the fixed horizontal plate. The fixed connection can be achieved by bolts or welding. The circular housing is used to accommodate the circular rod and provide a sliding limit function. The circular rod is movably connected inside the circular housing. The circular rod is used to insert into the positioning groove to lock the T-shaped suspension block. The front end of the circular rod passes through the rear side of the fixed horizontal plate and is located in the T-shaped groove. The rear end of the circular rod passes through the inner wall of the circular housing and is connected to a pull block. The pull block is used to manually control the extension, retraction, and rotation of the circular rod.
[0009] Preferably, a positioning groove is provided on the rear side of the T-shaped suspension block, and the front end of the circular rod is inserted into the positioning groove. The positioning groove is used to cooperate with the front end of the circular rod to achieve mechanical locking.
[0010] Preferably, the outer wall of the circular rod, near the front end, is provided with an annular slider, and the outer wall of the annular slider is in contact with the inner wall of the circular shell.
[0011] Preferably, an internally threaded fixing tube is provided inside the circular housing near the rear end. The internally threaded fixing tube is used to cooperate with the external thread to fix the retracted position of the circular rod. The outer wall of the circular rod is provided with an external thread that matches the internally threaded fixing tube. When it is necessary to disassemble the reactive power compensation box body, the operator first pulls the pull block backward to move the circular rod backward and separate it from the positioning groove. Then, the operator rotates the pull block to make the external thread connect with the internally threaded fixing tube, thereby fixing the position of the circular rod and preventing the circular rod from resetting, so as to release the positioning of the T-shaped suspension block. After that, the operator moves the reactive power compensation box body upward to move the T-shaped suspension block out of the T-shaped groove, which makes it easier for the operator to disassemble the reactive power compensation box body.
[0012] Preferably, a spring is sleeved on the outer side of the circular rod. The spring provides elastic restoring force to push the circular rod into the positioning groove. The front end of the spring abuts against the rear side of the annular slider, and the rear end of the spring abuts against the front side of the internally threaded fixing tube.
[0013] Preferably, the concave surface of the fixed clamp is provided with a first rubber liner, which is used to increase the friction with the support column, and the concave surface of the movable clamp is provided with a second rubber liner, which is used to protect the surface of the support column and enhance the clamping stability.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The fixed structure of this reactive power compensation box replaces the existing servo motor drive structure with a manually operated quick-release component and mechanical positioning parts, avoiding additional power consumption. Moreover, the reactive power compensation box can still be installed and disassembled in the event of power failure or power outage, which significantly improves the safety of on-site operation and environmental adaptability.
[0015] 2. The fixing structure of this reactive power compensation box adopts a mechanical locking method with T-slot and elastic positioning component, replacing the traditional screw and slider structure. This avoids the jamming problem caused by dust and impurities in the screw threads, reduces the difficulty of equipment disassembly and maintenance, and extends the service life.
[0016] 3. The fixing structure of the reactive power compensation box, combined with the sliding guide design of the T-shaped suspension block and T-shaped groove, and the locking structure of the round rod driven by the spring, realizes the quick suspension positioning and locking of the reactive power compensation box, improving the efficiency of disassembly and assembly.
