Description

Technical Field

[0001] The invention belongs to the technical field of unit maintenance devices, and in particular relates to a visualized electromagnetic force rope. Background Art

[0002] In power plants, the units are inspected and maintained every year. In particular, hot work and some modification work in the wind tunnel of the generator may cause some metal gaskets, metal wires, metal chips and other metal foreign objects to fall into the stator slots. Due to the structure of the generator stator, some metal foreign objects are not cleaned up in time. During the operation of the generator, these "slippery fish" will threaten the insulation layer of the stator wire rods, and over time will damage the insulation of the stator wire rods, which may eventually cause the stator to be grounded during the operation of the generator, resulting in a generator tripping accident.

[0003] At present, even if some isolation and protection measures are adopted for hot work and some renovation work in the wind tunnel, these measures cannot 100% guarantee that no metal chips will fall into the stator wire rods. Once metal falls into the stator wire slot, the common solutions at this stage are: 1. Adsorption method: use a strong vacuum cleaner for comprehensive adsorption; 2. Forward purge: use low-pressure dry compressed air to clean one by one; 3. Use a flashlight and endoscope for comprehensive inspection. Although the current solution can clean most of the metal foreign matter to a certain extent, this method is time-consuming, requires a lot of human resources, and is also limited by space.

[0004] In the actual maintenance process, in addition to the special parts of the wind tunnel, there are also some electrical equipment modifications. There are many internal wirings in the cabinet, and the space is relatively narrow. Metal foreign objects will fall to the bottom of the cabinet, and it is very difficult to clean these metal foreign objects. However, if these metal foreign objects are not cleaned, there will be hidden dangers in the operation of the equipment. Faced with this situation of narrow space, some ordinary tooling has low work efficiency and hidden dangers in the operation of the equipment. Summary of the invention

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0037] like Figure 1 and Figure 2 As shown, the visualized electromagnetic force rope of this embodiment includes a controller, one end of the controller is connected to a guide tube, a rechargeable battery is installed in the controller, a coil group with an iron core is installed in the guide tube, a button switch group is electrically connected between the rechargeable battery and the coil group with the iron core, and a micro lens is installed at the end of the guide tube away from the controller.

[0038] The present invention utilizes the principle of endoscope to find the metal foreign matter that needs to be cleaned, utilizes the principle that the coil with iron core generates magnetism to attract the metal foreign matter, divides the coil with iron core into groups and arranges them in an array, controls the coils of different groups through multiple switches, and makes the coil group that needs to be magnetic generate magnetism.

[0039] The corresponding number of core coils and control buttons can be increased according to actual needs, and the length and inner diameter of the guide tube can be designed according to the specific application scenario.

[0040] The present invention can be used to clean metal foreign bodies in special narrow spaces, thus avoiding waste of manpower, greatly improving work efficiency, and effectively improving the stability of equipment operation.

[0041] The coils of the present invention are grouped, and each switch independently controls each group of coils, which has great flexibility. Even if a coil is damaged, it will not affect other groups of coils, and the fault tolerance rate is high.

[0042] The present invention adopts a plurality of coils which are placed close to each other so that their N poles and S poles are opposite to each other, and the two coils directly generate a strong magnetic field.

[0043] The present invention has a wide range of application scenarios and can be used in small and space-restricted areas, so it is popularizable.

[0044] The wiring of the invention is simple and reasonable, not easy to be damaged, and the size and model of the guide tube can be changed according to the needs.

[0045] The invention is easy to carry, and the power supply is a battery, so there is no need to take power for the device separately.

[0046] The present invention greatly improves the efficiency of cleaning metal foreign bodies in a narrow space, avoids waste of manpower, and improves work efficiency.

[0047] Furthermore, the controller is also equipped with a liquid crystal display screen, which is electrically connected to the micro lens, and the micro lens and the liquid crystal display screen are both electrically connected to a rechargeable battery. After the device is powered on, the foreign matter that needs to be cleaned is found through the frontmost micro lens, and the found foreign matter can be intuitively displayed on the liquid crystal display screen.

[0048] Specifically, the iron core coil group includes a plurality of iron core coils, and the button switch group includes a plurality of button switches. The frontmost iron core coil is electrically connected to the positive pole of the rechargeable battery through a button switch, the rear end of the front iron core coil is connected to the front end of the adjacent iron core coil on the rear side through an electric wire and then electrically connected to the positive pole of the rechargeable battery through a button switch, and the rear end of the rearmost iron core coil is electrically connected to the negative pole of the rechargeable battery.

[0049] By controlling each button switch, the energization of each coil with an iron core can be controlled respectively, so that the coil with an iron core at a determined position can be energized to absorb iron filings. In the present invention, each coil is grouped, and each switch independently controls each group of coils, which is highly flexible. Even if a coil is damaged, it will not affect other groups of coils, and the fault tolerance rate is high.

[0050] In order to facilitate the fixing of the coil with iron core, a plurality of component installation grooves are arranged in the guide tube, and the coil with iron core is installed in the component installation groove. Each coil with iron core is placed in each component installation groove separately to prevent interference between each other and loose circuit.

[0051] In this embodiment, the number of the iron core coil and the number of the button switches are both three.

[0052] In order to facilitate the adjustment of the direction of the guide tube, a connecting tube is connected between the guide tube and the controller, and the connecting tube is made of a flexible material. Since the connecting tube is flexible, the guide tube can be bent relative to the controller, so that the guide tube can be accurately inserted between the two stator bars.

[0053] Furthermore, a current limiting resistor is connected to the connection circuit of the rechargeable battery to prevent the situation where the coil resistance is too small and the circuit current is too large.

[0054] In order to conveniently control the direction of the micro lens, a pressure spring is also arranged in the guide tube, one end of the pressure spring is connected to the micro lens, and the other end of the pressure spring is connected to a direction controller, which is arranged on the controller. After the device is powered on, the foreign matter to be cleaned is found through the frontmost micro lens, and the pressure spring inside the device can be adjusted through the direction controller to control the direction of the micro lens to accurately find the metal foreign matter.

[0055] Wherein, the pressure spring is a torsion spring, the direction controller is a control ring sleeved on the controller, and the control ring is connected to the torsion spring.

[0056] After the circuit is designed, the iron core coil, pressure spring, micro lens and some cables can be installed in the component installation slot of the guide tube, and finally the guide tube is packaged as a whole. The rechargeable battery, current limiting resistor, button switch, LCD screen, direction controller and other components are installed in the controller, isolating the control part from the electromagnetic force rope to avoid the occurrence of difficult operation of the control part in complex environments.

[0057] Use scenarios:

[0058] A visual electromagnetic force rope is used in special narrow spaces, such as Figure 3As shown, in order to clean the iron filings between two stator bars in a narrow space in the vertical direction, the guide tube is first placed between the two stator bars. After the device is powered on, the foreign matter to be cleaned is found through the micro lens at the front end. The found foreign matter can be intuitively displayed on the LCD screen. The direction controller can also be used to adjust the pressure spring inside the device to control the direction of the micro lens to find the metal foreign matter. After the metal foreign matter is found, the iron core coil inside the guide tube is energized to generate magnetism by closing the button switch, which can immediately attract the metal foreign matter, and then the guide tube and the metal foreign matter are taken out.

[0059] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention.
