Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this utility model without making creative efforts shall fall within the protection scope of this utility model.

[0030] Please refer to Figure 1 and Figure 2, the present utility model provides a technical solution: a corrosion-resistant low-voltage reactor, including a base 1. A plurality of solenoids 2 are installed on the upper surface of the base 1. A plurality of connecting feet 4 are electrically connected to the upper surface of the solenoids 2. A top plate 3 is installed on the upper surface of the plurality of solenoids 2. The connecting feet 4 penetrate through the top plate 3. Bolts 5 are threadedly connected to the surfaces of the plurality of connecting feet 4. Two foot plates 6 are electrically connected to the arc surface of the solenoids 2. A shielding structure 7 is provided on the upper surface of the top plate 3, achieving the effect of shielding the bolts 5 of the low-voltage reactor, thus minimizing the problem that the bolts 5 are corroded by rainwater and are difficult to remove due to thread slippage during the later disassembly process. A collecting structure 8 is provided on the upper surface of the top plate 3, achieving the effect of collecting the bolts 5 after disassembly. After the bolts 5 are centrally collected, it is convenient for later personnel to quickly pick up and install them, avoiding the situation of random placement and loss, reducing the maintenance cost and improving the work efficiency of personnel.

[0031] Next, specifically describe the specific settings and functions of its shielding structure 7 and collecting structure 8.

[0032] As Figures 2 - 5 shown, the shielding structure 7 includes a fixing frame 701. The lower surface of the fixing frame 701 is fixedly connected to the top plate 3. A circular tube 702 is fixedly connected to the inner wall of the fixing frame 701. A spring 703 is fixedly connected to the inner wall of the circular tube 702. A long rod 704 is slidably connected to the other end of the spring 703 in the inner wall of the circular tube 702. The lower end of the long rod 704 is fixedly connected to a connecting plate 705. Two protective boxes 706 are fixedly connected to both sides of the connecting plate 705. A plurality of bolts 5 are all located within the two protective boxes 706. A bent rod 707 is fixedly connected to the arc surface of the circular tube 702. A rotating frame 708 is fixedly connected to the upper surface of the connecting plate 705. A U-shaped rod 709 is rotatably connected to the inner wall of the rotating frame 708. The inner wall of the U-shaped rod 709 is slidably connected to the bent rod 707. When the U-shaped rod 709 is rotated to the arc surface of the bent rod 707, the bent rod 707 plays a role in temporarily positioning the expansion and contraction of the spring 703. Bottom grooves 710 are opened on the upper surface of the top plate 3 at positions corresponding to the two protective boxes 706. The protective boxes 706 are located within the bottom grooves 710. When the protective boxes 706 move into the bottom grooves 710, the bottom grooves 710 achieve the effect of positioning the protective boxes 706. Two pulling grooves 711 are evenly opened on both sides of the connecting plate 705. A sealing pad 712 is fixedly connected to the lower surface of the protective box 706. The lower surface of the sealing pad 712 abuts against the inner groove. When the protective box 706 drives the sealing pad 712 to move into the inner groove, the sealing pad 712 plays a role in improving the sealing performance of the protective box 706.

[0033] As Figure 5As shown, the collection structure 8 includes an inclined block 81. The lower surface of the inclined block 81 is fixedly connected to the top plate 3. The inclined surface of the inclined block 81 is fixedly connected to an acrylic box 82. One side of the acrylic box 82 is fixedly connected to an extension plate 83. A sliding hole 84 is formed on one side of the acrylic box 82. The inner wall of the sliding hole 84 is slidably connected to a driving frame 85. One side of the driving frame 85 relative to the inside of the acrylic box 82 is fixedly connected to a push plate 86. The driving frame 85 moves the push plate 86 to push the bolt 5 inside the acrylic box 82. The push plate 86 serves to facilitate the pushing out of the internal bolt 5. A strip bar 87 is fixedly connected to the inner wall of the sliding hole 84. The lower surface of the driving frame 85 is slidably connected to the strip bar 87. The driving frame 85 slides on the surface of the strip bar 87 inside the sliding hole 84. The strip bar 87 achieves the effect of increasing the friction strength between the driving frame 85 and the sliding hole 84 so that it can stop sliding to a certain extent.

[0034] Working principle: When a low-voltage reactor needs to be used, first install the base 1 and the connecting seat, and then connect the foot plate 6 to the equipment. During operation, due to the effect of electromagnetic induction in the circuit, there is a certain inductance. When the low-voltage reactor is connected to the circuit, the circuit impedance transformation can be realized by means of the power conversion unit, so as to realize the adjustment of high and low voltage and reactive power compensation and can play a role in preventing current changes. When rain falls, a protective film is wrapped on the surface of the solenoid 2, so that the rainwater will not invade the surface of the solenoid 2, and the external protective box 706 of the bolt 5 is used to block the rainwater. The rainwater on the surface of the top plate 3 is blocked again by the sealing pad 712 and the bottom groove 710, so as to avoid the rainwater invading and corroding the thread of the bolt 5 and causing the thread to slip. When the connecting foot 4 is replaced and maintained later, the connecting plate 705 is driven to pull away from the top plate 3 by means of the pulling groove 711. The protective box 706 drives the sealing pad 712 to disengage from the inner wall of the inner groove through the connecting plate 705. The bottom groove 710 achieves the effect of positioning the protective box 706. At this time, the bolt 5 is exposed, and the long rod 704 slides from the inner wall of the round tube 702 to squeeze the spring 703 through the connecting plate 705. At this time, the spring 703 is in a compressed state. After being lifted to a certain height, the U-shaped rod 709 is rotated through the rotating frame 708 to the arc surface of the bent rod 707. The bent rod 707 serves to temporarily position the expansion and contraction of the spring 703. Then the connecting plate 705 is released. At this time, due to the limit between the U-shaped rod 709 and the bent rod 707, the spring 703 is temporarily limited and cannot expand. After the bolt 5 is taken out and collected by the collection structure 8, the connecting foot 4 is maintained and replaced. After the replacement is completed and the bolt 5 is connected to the connecting foot 4, the U-shaped rod 709 is rotated through the rotating frame 708 to disengage from the bent rod 707. At this time, the spring 703 is in an expanded state, driving the long rod 704 to slide out of the round tube 702. The connecting plate 705 drives the protective box 706 to block the bolt 5 through the long rod 704. The sealing pad 712 is attached to the inner wall of the inner groove through the protective box 706. The sealing pad 712 serves to improve the sealing performance of the protective box 706, thereby blocking the bolt 5 again.

[0035] When it is necessary to collect the bolts 5, the bolts 5 are placed into the acrylic box 82 from the bottom of the extension plate 83. The inclined acrylic box 82 of the inclined block 81 quickly slides the bolts 5 to the inside. When in use, the driving frame 85 is moved towards the side close to the extension plate 83. The driving frame 85 slides on the upper surface of the bar 87 in the sliding hole 84. The bar 87 achieves the effect of increasing the frictional strength between the driving frame 85 and the sliding hole 84 so that the sliding can be stopped to a certain extent. The push plate 86 then pushes the bolts 5 in the acrylic box 82 to the position of the box opening through the driving frame 85. And through the continuous taking of the bolts 5, the push plate 86 can be moved again to push out the bolts 5 inside. The push plate 86 plays the role of facilitating the pushing out of the bolts 5 inside.
