Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an anti-interference AC filter. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. Filters can effectively filter out specific frequencies or frequencies outside of a power supply line to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency has been eliminated. In DC transmission systems, in order to filter out harmonics generated by the DC control system to avoid adverse effects on the AC transmission system, and to compensate for the reactive power consumed by the DC control system, a certain number of AC filters must be in operation during DC system operation. AC filters consist of capacitors, reactance, and resistors connected in series and parallel.

[0003] Currently, some anti-interference AC filters are used by connecting the input and output ports of the filter through connecting cables. When the connecting cables are installed and removed from the filter, they may be repeatedly bent, and friction may occur between the connecting cables and rigid pipes, which may lead to fatigue fracture of the connecting cables and affect their service life. Utility Model Content

[0004] The purpose of this invention is to provide an anti-interference AC filter to solve the problem that the service life of some connecting wires may be shortened due to repeated bending at the connection point with the filter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference AC filter, comprising a filter body, and further comprising:

[0006] Mounting plates are fixedly connected to both sides of the filter body, and connecting pipes are respectively provided on both sides of the filter body;

[0007] An adjustment assembly is disposed on the outside of the connecting pipe. The adjustment assembly includes a sliding tube disposed on one side of the connecting pipe, an adjustment ball is rotatably connected inside the sliding tube, an outer tube is fixedly connected to the outside of the adjustment ball, and a flexible tube is connected to the side of the outer tube away from the adjustment ball.

[0008] Preferably, the adjusting ball has a threading hole inside, and the outer tube has a pull rod slidably connected inside.

[0009] Preferably, a flexible plate is fixedly connected to one end of the pull rod, and a spring is sleeved on the outside of the pull rod, with one end of the spring welded to the outside of the pull rod.

[0010] Preferably, one end of the spring is welded to the inner wall of the outer tube, and the number of springs is set to two.

[0011] Preferably, a mounting plate is fixedly connected to the outside of the connecting pipe, and one side of the mounting plate is fixedly connected to one side of the filter body.

[0012] Preferably, a placement tube is fixedly connected to the side of the connecting tube away from the mounting plate, and the placement tube has multiple slots inside.

[0013] Preferably, a bolt is slidably connected to the outer side of the connecting pipe, and a tapered pipe is fixedly connected to one side of the bolt. The inner wall of the tapered pipe is threadedly connected to the outer side of the placement pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention features an adjustment component. The connecting wire enters the connecting tube through a threading hole and connects to the filter body. Under the action of the outer tube and the rotating ball, the placement angle of the rotating ball inside the sliding tube can be adjusted. At the same time, under the action of two flexible plates and spring force, the outer side of the connecting wire can be clamped and protected to prevent the connecting wire from bending or breaking. In addition, the flexible hose facilitates the adjustment of the placement position and angle of the connecting wire by the operator, preventing wear between the connecting wire and the inner wall of the rigid pipe, thereby extending the service life of the connecting wire.

[0021] 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.

[0022] Please see Figure 1-4 As shown, an anti-interference AC filter includes a filter body 1. The AC filter is mainly used to suppress or eliminate harmonic interference in AC circuits. Its working principle is based on the frequency selectivity of the circuit. By connecting inductors, capacitors, and resistors in series or parallel, a resonant circuit is formed, presenting high or low impedance to signals of specific frequencies, thereby achieving a filtering effect. This is existing technology, and the specific structure, working principle, and possible control and spatial arrangement methods of these technical features can be conventionally selected in this field, and will not be elaborated here. It also includes:

[0023] Mounting plates 2 are fixedly connected to both sides of the filter body 1. With the help of the two mounting plates 2, it is convenient for the staff to install and position the filter body 1. Connecting pipes 3 are respectively provided on both sides of the filter body 1. With the help of the connecting pipes 3, it is convenient for the staff to connect the input port and output port of the filter body 1.

[0024] Adjustment component 4 facilitates the adjustment of the placement angle of the connecting cable by the operator, preventing excessive bending of the connecting cable and thus reducing its service life. Located on the outside of the connecting tube 3, adjustment component 4 includes a sliding tube 41 on one side of the connecting tube 3. The sliding tube 41 facilitates the connection and disassembly of the sliding tube 41 and the placement tube 12, thereby facilitating the connection and disassembly of the connecting cable. An adjusting ball 42 is rotatably connected inside the sliding tube 41. Both the outer side of the adjusting ball 42 and the inner wall of the sliding tube 41 are coated with a rubber coating, ensuring the adjusting ball 42 remains stable after angle adjustment. An outer tube 43 is fixedly connected to the outer side of the adjusting ball 42, facilitating the adjustment of the placement angle of the connecting cable. A flexible hose 44 connects to the side of the outer tube 43 away from the adjusting ball 42, allowing for easy adjustment of the placement angle of the connecting cable and preventing wear on the outer side of the connecting cable.

[0025] refer to Figure 2 , Figure 3 and Figure 4As shown, the adjusting ball 42 has a wire-passing hole 5 inside, which facilitates the connection of the connecting wire to the filter body 1. When the adjusting ball 42 rotates, it can also rotate part of the connecting wire. A pull rod 7 is slidably connected inside the outer tube 43. When the pull rod 7 moves, it can move the flexible plate 6. One end of the pull rod 7 is fixedly connected to the flexible plate 6, and a spring 8 is sleeved on the outside of the pull rod 7. One end of the spring 8 is welded to the outside of the pull rod 7, and the other end is welded to the inner wall of the outer tube 43. Under the elastic force of the spring 8, the flexible plate 6 can withstand the elastic force from the spring 8, allowing the flexible plate 6 to move to a designated position. The two flexible plates 6 can then clamp and position the connecting wire inside the outer tube 43. Two springs 8 are used. A mounting plate 9 is fixedly connected to the outside of the connecting tube 3. The mounting plate 9 facilitates the positioning and disassembly of the connecting tube 3 by the operator. The connecting tube 3 is fixedly connected to one side of the filter body 1. The side of the connecting tube 3 away from the mounting plate 9 is fixedly connected to the placement tube 12. Under the action of the placement tube 12, the connecting wire can be connected to the filter body 1 through the placement tube 12. The placement tube 12 has multiple slots 13 inside. The outer side of the connecting tube 3 is slidably connected to the bolt 10. Under the action of the bolt 10, when the bolt 10 rotates, it can drive the tapered tube 11 to move, thereby moving the tapered tube 11 to the designated position. The tapered tube 11 is fixedly connected to one side of the bolt 10. Under the action of the tapered tube 11, the placement tube 12 can be clamped. When the bolt 10 is rotated, the bolt 10 can drive the tapered tube 11 to move. Then, the smaller diameter end of the tapered tube 11 can apply a certain pressure to the placement tube 12, thereby causing a certain degree of deformation in the part of the placement tube 12 with slots 13, thereby positioning and clamping the sliding tube 41. The inner wall of the tapered tube 11 is threadedly connected to the outer side of the placement tube 12.

[0026] Working principle: When the operator needs to use the filter body 1 in this device, firstly, according to the actual needs, connect the connecting wires of the output port and input port of the filter body 1. First, let the connecting wire enter the interior of the outer tube 43 through the flexible tube 44. Then, pull the lever 7, which will compress the spring 8, thereby causing the flexible plate 6 to disengage from its initial position. Then, let the connecting wire pass through the wire hole 5, and let the connecting wire enter the interior of the connecting tube 3 through the sliding tube 41, thus connecting the connecting wire and the filter body 1. Then, the operator rotates the bolt 10, so that the bolt 10 can drive the tapered tube 11 to... The outer side of the placement tube 12 rotates, which simultaneously adjusts the position of the tapered tube 11 on the outer side of the placement tube 12. The smaller diameter end of the tapered tube 11 applies greater pressure to the part of the placement tube 12 with the slot 13, thereby allowing the sliding tube 41 to be tightly connected to the placement tube 12. Then, the operator rotates the adjusting ball 42, which can drive part of the connecting wire to adjust the angle, thereby preventing the connecting wire from being excessively bent, which would reduce the service life of the connecting wire. At the same time, the flexible hose 44 can provide a certain degree of protection for the connecting wire, so that the connecting wire will not break or detach.
