Description

Technical Field

[0001] The present invention relates to the technical field of shielding of equipment or components against electric fields or magnetic fields, and in particular to an electromagnetic interference prevention device integrating power line communication and sensing. Background Art

[0002] In industrial sites, the distribution of power supply and distribution lines is similar to a network that gathers various interferences, and the interference can be easily spread to various places through circuit conduction, invading from the power line of the detection device to the inside of the instrument to cause interference. The most obvious phenomenon is the voltage mutation and AC power waveform distortion, which causes the high-order harmonics of the power frequency to be transmitted to the front-stage circuit of the equipment through the power line. For example, the thyristor in the voltage regulation or inverter circuit may cause high-power high-order harmonic interference, or the switching power supply may spread hundreds of kilohertz sharp pulse interference from the power line.

[0003] Existing equipment, such as a power line communication and sensing integrated device with anti-electromagnetic interference function (Announcement No. CN110996640B), still has the following shortcomings:

[0004] The above technical solution uses absorbing foam to protect electronic products from interference. However, relying solely on absorbing foam for protection cannot achieve stable protection of electronic products, and electromagnetic interference is still prone to occur.

[0005] Furthermore, the above technical solution does not have a corresponding ventilation protection device, which makes it difficult to dissipate the heat generated by the electronic equipment during normal operation. At the same time, absorbing foam is used for electromagnetic interference protection, making it even more difficult for the heat of the electronic equipment to dissipate.

[0006] In view of the above problems, the present invention document proposes a power line communication sensor integrated anti-electromagnetic interference device. Summary of the invention

[0042] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0044] Example 1

[0045] Reference Figure 1-Figure 12 The embodiment of the invention is a power line communication sensor integrated anti-electromagnetic interference device, comprising a box 1, and multiple vents 3 are evenly provided on the inner walls of both sides of the box 1 to ensure air circulation in the box to achieve heat dissipation effect. Two door panels 2 are symmetrically hinged at the opening of the box 1 to facilitate opening and closing the box. A partition 49 is fixedly installed inside the box 1 to separate the internal space of the box into two parts, upper and lower.

[0046] On both sides of the partition 49, a plurality of supporting mechanisms are symmetrically fixedly installed. Each supporting mechanism includes two guide rails 5, which are respectively installed on one side of the partition 49 and one inner wall of the box body 1. A limiting slide 6 is slidably connected in the guide rail 5, and the tops of the two limiting slides 6 extend into the box body 1, and a support plate 7 is fixedly installed together. The top of the support plate 7 is used to place electronic products, and two ventilation holes are symmetrically opened on the support plate 7 to further improve the heat dissipation effect. A fixing mechanism is installed on the top of the support plate 7 for clamping and positioning the electronic products.

[0047] The grounding mechanism is installed on one side of the box body 1, and one side thereof extends into the box body 1 and is respectively connected to a plurality of supporting mechanisms. The function of the grounding mechanism is to provide grounding protection for electronic products to reduce electromagnetic interference.

[0048] The ventilation mechanism is installed on the outside of the box body 1, and one side thereof extends into the box body 1 and penetrates the partition plate 49 to be connected with the partition plate 49. The ventilation mechanism can be a fan or other ventilation equipment to accelerate the air circulation in the box body and improve the heat dissipation efficiency.

[0049] Furthermore, the design of the supporting mechanism allows the support plate 7 to be easily pulled out. When the electronic product needs to be installed or maintained, the support plate 7 can be pulled outward by the handle 71 until the support plate 7 is completely moved out of the box 1. At this time, the first magnet 8 and the second magnet 10 will attract and engage each other, thereby braking and limiting the support plate 7 to prevent the support plate 7 from moving at will.

[0050] The design of the fixing mechanism ensures that the electronic products can be stably fixed on the support plate 7. The fixing mechanism includes two limit bars 29, which are symmetrically fixed on the top of the support plate 7. At the same time, a plurality of U-shaped binding plates 31 are also prepared, and the two sides of these U-shaped binding plates 31 can be respectively inserted into the two limit bars 29. After the electronic products are placed on the support plate 7, the electronic products can be bound and braked using a plurality of U-shaped binding plates 31. Then, the U-shaped binding plates 31 are clamped and positioned by the brake assembly. The brake assembly includes a pressure strip 30 slidably connected to the limit bars 29, as well as a plurality of nuts 32 and a fixing screw 33. By rotating the fixing screw 33, it can be moved downward under the threaded transmission of the nut 32, thereby driving the pressure strip 30 to move downward and clamping and positioning the U-shaped binding plate 31.

[0051] In the integrated anti-electromagnetic interference equipment of power line communication sensor, the design of grounding mechanism is crucial to protect electronic products from electromagnetic interference. We can implement the following grounding mechanism in detail:

[0052] First, we fix multiple grounding plates 11 on the top of each support plate 7. Multiple grounding contacts 111 are arranged in a matrix on the top of these grounding plates 11. These grounding contacts 111 can form good electrical contact with the electronic products placed on the grounding plates 11, ensuring that the electronic products can be grounded through the grounding plates 11.

[0053] At the four corners of the bottom of the grounding plate 11, we fixedly installed transmission poles 12. The bottom ends of the four transmission poles 12 all penetrate the support plate 7 and extend to the bottom of the support plate 7. In order to enhance the conductive effect, we fixedly connected the bottom ends of the two transmission poles 12 on the same side to the same conductive pole 13. One end of the conductive pole 13 is fixedly connected to a power receiving cover 14.

[0054] On one side inner wall of the box body 1, we symmetrically fixedly installed multiple power transmission boards 15. Two plugs 16 are symmetrically fixedly installed on one side of each power transmission board 15. One end of these plugs 16 extends into the corresponding power connection cover 14 and is electrically plugged with the power connection cover 14. In this way, the current on the grounding plate 11 can be transmitted to the power transmission board 15 through the power transmission rod 12, the conductive rod 13, the power connection cover 14 and the plug 16.

[0055] A guide rod is fixedly connected to the other side of the power transmission plate 15. A protective cover 19 is fixedly installed on one side of the box body 1. One end of multiple guide rods located on the same side extends into the protective cover 19 and is fixedly connected to the same first power transmission pole 17. A power connection plate 18 is fixedly connected to the bottom ends of the two first power transmission poles 17. A second power transmission pole 20 is fixedly installed on one side of the power connection plate 18.

[0056] One end of the second transmission pole 20 extends to the outside of the protective cover 19 and is connected to the ground insertion assembly. The ground insertion assembly includes a slide rail 23 fixedly mounted on one side of the protective cover 19. A transmission slide plate 25 is slidably connected to the slide rail 23, and a grounding pole 22 is fixedly mounted at the bottom of the transmission slide plate 25. One end of the second transmission pole 20 is electrically connected to a conductive ring 21, and the grounding pole 22 penetrates the conductive ring 21 and is in sliding electrical contact with the inner wall of the conductive ring 21.

[0057] A support plate 26 is fixedly installed on the top of the transmission slide plate 25. A plug rod 27 is slidably connected to the support plate 26. Two slots 24 are provided on one side of the slide rail 23. The plug rod 27 can be movably mounted with the two slots 24. At the same time, a compression spring 28 is also sleeved on the plug rod 27. The two ends of the compression spring 28 are fixedly connected to the plug rod 27 and one side of the support plate 26 respectively.

[0058] When the grounding rod 22 needs to be inserted into the ground for grounding, we can push the transmission slide plate 25 downward. In this way, the grounding rod 22 will be inserted into the ground. At the same time, when we move the insertion rod 27 to the position corresponding to the slot 24 below, we can release the insertion rod 27. At this time, the compression spring 28 in a stressed state will push the insertion rod 27 to move, so that the insertion rod 27 is inserted into the slot 24.

[0059] At this time, the current flowing out through the second transmission pole 20 can flow to the ground through the conductive ring 21 and the grounding pole 22. In this way, we can protect the electronic products from electromagnetic interference through grounding.

[0060] In the integrated anti-electromagnetic interference device for power line communication sensing, a specific ventilation mechanism is designed to achieve ventilation and heat dissipation in the box. The mechanism includes a carrier plate 34 fixedly mounted on the other side of the box. A conveying component is connected through the carrier plate 34 to convey external gas into the box.

[0061] The bottom of the delivery assembly is connected to a gas delivery pipe 36, the bottom end of which extends into the box and passes through the partition 49 to be fixedly connected to the partition 49. One end of the gas delivery pipe 36 is fixedly connected to the inner wall of the bottom of one side of the box. Four mounting pipes are fixedly installed on the gas delivery pipe 36, and the four mounting pipes are symmetrically arranged on both sides of the partition 49. In this way, the gas can be delivered to different positions in the box through the four mounting pipes.

[0062] Example 2

[0063] Reference Fig. 9 and Fig.10 This embodiment is based on the first embodiment. Regarding the integrated anti-electromagnetic interference device for power line communication sensing proposed in the first embodiment, in order to more effectively disperse the gas into the box, we fixedly installed rectangular tubes 37 on both sides of the partition 49. One side of the rectangular tube 37 is fixedly connected to the bottom inner wall of one side of the box. In the rectangular tube 37, we fixedly installed a plurality of nozzles 38 at equal intervals. The top ends of the two installation tubes on the same side extend into the corresponding rectangular tube 37 and are fixedly connected to the bottom inner wall of the rectangular tube 37.

[0064] When the conveying assembly is started, the external gas is sucked into the gas delivery pipe 36, and then conveyed to the rectangular tube 37 through the installation pipe. The gas entering the rectangular tube 37 is blown upward by multiple nozzles 38. Since the support plate 7 is provided with ventilation holes, the gas can drift upward through the ventilation holes to achieve a ventilation effect in the box. In this way, the electronic products can be effectively ventilated and heat-dissipated.

[0065] The specific structure of the conveying assembly includes an air cylinder 35 that penetrates the carrier plate 34 and is fixedly connected to the carrier plate 34. The bottom of the air cylinder 35 is fixedly connected to the other end of the air delivery pipe 36. A dustproof screen 40 is fixedly installed at the top opening of the air cylinder 35. An axial flow blade 41 is rotatably connected to the dustproof screen 40. A scraper rod 42 located above the dustproof screen 40 is fixedly installed on the axial flow blade 41, and the scraper rod 42 contacts the top of the dustproof screen 40.

[0066] A driving motor 39 is fixedly mounted on the top of the carrier plate 34. A synchronous wheel 43 is fixedly mounted on the output shaft of the driving motor 39 and the top of the axial flow blade 41. The two synchronous wheels 43 are connected to the same synchronous belt 44. When the driving motor 39 is started, the axial flow blade 41 can be driven to rotate through the transmission cooperation of the two synchronous wheels 43 and the synchronous belt 44.

[0067] The axial flow blades 41 generate suction when rotating, so that the external gas is sucked into the air cylinder 35, forming a directional wind force to be transported into the air delivery pipe 36. The dustproof screen 40 can filter the dust in the gas, so that the gas entering the box is in a clean state. At the same time, the scraper 42 can scrape the top of the dustproof screen 40 as the axial flow blades 41 rotate, thereby preventing the dust from clogging the dustproof screen 40.

[0068] In addition, in order to further improve the anti-electromagnetic interference capability of the device, we fixedly installed a mounting plate 47 on one side of the top of the support plate 7. A mounting frame 45 is fixedly installed on one side of the mounting plate 47. In the mounting frame 45, we fixedly installed a honeycomb shielding net 46 and two isolation mesh panels 48 located on both sides of the honeycomb shielding net 46. A mounting frame 4 is slidably mounted on the mounting frame 45, and the mounting frame 4 is fixedly mounted on one inner wall of the box body.

[0069] The isolation mesh plate 48 can filter the dust in the gas, and the honeycomb shielding mesh 46 can absorb the charge in the gas, thereby preventing the charge in the external gas from entering the box. In this way, the electronic products can be protected from electromagnetic interference.

[0070] Meanwhile, when installing or removing the support plate 7, the mounting frame 45 can be drawn out from the mounting frame 4. When the mounting frame 45 is moved out of the box along with the support plate 7, the isolation mesh plates 48 on both sides can be easily cleaned, thereby ensuring the continuous and effective operation of the equipment.

[0071] Working principle: first, pull the support plate 7 out of the box body 1, and make the first magnet 8 and the second magnet 10 be attracted, so as to brake and limit the support plate 7 to prevent the support plate 7 from moving at will. Then, the electronic product can be placed on the grounding plate 11, and then a plurality of U-shaped binding plates 31 are used to bind and brake the electronic product. After the two sides of the U-shaped binding plates 31 are respectively inserted into the corresponding limiting strip frames 29, by rotating a plurality of fixing screws 33, under the threaded transmission action of the corresponding nuts 32, the pressure strip 30 can be driven to move downward, and the plurality of U-shaped binding plates 31 can be clamped and positioned, so that the U-shaped binding plates 31 can stably bind the electronic product. Then, the support plate 7 can be pushed to move the electronic product into the box body 1. After all the electronic products are clamped and fixed and moved into the box 1, the two door panels 2 can be closed to put the numerous electronic products in a relatively closed state. Then, the grounding rod 22 can be inserted into the ground surface by pushing the transmission slide plate 25 downward, and when the plug 27 is moved to a position corresponding to the slot 24 below, the plug 27 can be released, and the compression spring 28 in a stressed state can push the plug 27 to move so that the plug 27 is inserted into the slot 24. At this time, after the interference current appears on the electronic product, the grounding plate 11 can be used to absorb it, and then it can be transmitted through the transmission rod 12, the conductive rod 13, the power connection cover 14, the plug 16, the transmission plate 15, the guide rod, the first transmission rod 17 and the second transmission rod 20, so that the current flows into the conductive ring 21, and then Afterwards, the grounding rod 22 inserted into the ground surface can lead the current into the earth, so as to realize the grounding protection of the electronic products. At the same time, the two-layer isolation mesh 48 can filter the dust in the gas, and the honeycomb shielding mesh 46 can absorb the charge in the gas, so as to prevent the charge attached to the external gas from entering the box body 1, so as to realize the electromagnetic interference protection of the electronic products. At the same time, when the support plate 7 is pulled, the installation frame 45 can be pulled out of the installation frame 4. When the installation frame 45 is moved out of the box body 1 along with the support plate 7, the isolation mesh 48 on both sides can be conveniently cleaned.
