Description
Technical Field
[0001] This application relates to the field of strong electromagnetic pulse protection technology, and in particular to a comprehensive strong electromagnetic pulse protection device with detection and display functions. Background Technology
[0002] With the development of society, more and more electronic devices are being used in people's lives. However, many electronic devices are very sensitive to overvoltages such as lightning and surges.
[0003] Lightning electromagnetic pulse protection is a key focus of power line protection because components on power lines are easily induced by external lightning electromagnetic pulses, which can carry and conduct large amounts of high-voltage lightning surges, thereby affecting the powered electronic equipment.
[0004] If the power transmission line is introduced overhead, it will be under the threat of direct lightning strikes. When struck by lightning, the surge in the line circuit is extremely high. At this time, the damage of lightning electromagnetic pulse to electronic equipment will also increase significantly. Relying solely on lightning rods on buildings is no longer sufficient to meet the exact needs of various weak electrical equipment for lightning protection. Summary of the Invention
[0005] In view of this, the purpose of this application is to provide a comprehensive protection device for strong electromagnetic pulses with detection and display functions, so as to solve the technical problem that the existing single lightning rod lightning protection measures can no longer adequately meet the specific needs of lightning protection for various weak electrical equipment.

[0024] The support block is rotatably mounted on the outer shell and located below the locking plate, for supporting the locking plate;
[0025] The support block can rotate on its own to support the lock plate when the lock plate is in the locked position;
[0026] The limiting member is used to fasten the support block to the outer shell when the support block supports the lock plate in the locked position.
[0027] Furthermore, the limiting member is elastically slidably connected to the outer shell along the rotation center line of the support block via an elastic member;
[0028] The support block is provided with a slot for the limiting member to be inserted;
[0029] The elastic element is used to provide an elastic force for the limiting element to move in the direction of engaging the slot;
[0030] When the support block supports the locking plate in the locked position, the limiting member can be moved into the slot under the action of the elastic member to fasten the support block to the outer shell.
[0031] Furthermore, the elastic element is a spring;
[0032] The outer casing is provided with a sliding groove for the limiting component to slide.

[0039] Furthermore, both the downward pressure limiting groove and the upward support limiting groove are U-shaped groove structures;

[0046] Furthermore, the display module includes a first counting indicator light and a second counting indicator light.
[0047] As can be seen from the above technical solutions, the strong electromagnetic pulse integrated protection device with detection and display functions designed in this application uses the lower pressure limiting groove and the upper support limiting groove to position the inserted cable. Then, the cable is clamped and fixed by the second locking block of the locking plate. At the same time, the lower pressure limiting groove and the upper support limiting groove are closed to make the inside of the shell relatively sealed with the outside.

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0059] This application discloses a comprehensive protection device for strong electromagnetic pulses with detection and display functions.
[0060] Please see Figure 1 One embodiment of a comprehensive protection device for strong electromagnetic pulses with detection and display functions provided in this application includes:
[0061] The main body of the device, protective components, and detection components.
[0062] The main body of the device includes an outer shell 1, a shell cover 2, a protective cover 3, a locking plate 6, and a locking assembly.
[0063] The housing 1 has a chamber for installing the component 11 to be protected. The top of the housing 1 has an opening, and the housing cover 2 is closable and can be installed on the opening. The housing cover 2 can be installed on the opening by rotation, so as to control the opening or closing of the opening, so as to facilitate the arrangement or maintenance of the interior of the chamber.
[0064] The upper end of one side wall of the outer casing 1 is provided with several upper support limiting grooves 5 for cables to pass through. The upper end refers to the part of a certain width that reaches the upper edge of the side wall. The protective cover 3 is hinged to the cover 2 and can fit against one side wall of the outer casing 1. The lower end of the protective cover 3 is provided with several lower pressure limiting grooves 4 for cables to pass through, which correspond one-to-one with the upper support limiting grooves 5.
[0065] The locking plate 6 is slidably installed on one side wall of the outer casing 1 in a vertical direction, and is provided with a number of first locking blocks 7 and a number of second locking blocks 8.
[0066] The locking assembly is installed on the housing 1 and is used to lock the locking plate 6 when the locking plate 6 is in the locked position. When the locking plate 6 is in the locked position, a number of first locking blocks 7 press against the protective cover 3 attached to one side wall of the housing 1. At the same time, a number of second locking blocks 8 are inserted into the pressure limiting groove 4 one by one and clamp the cable passing through the groove 4.
[0067] In this application, the upper end of the side wall of the outer shell 1 with the upper support limiting groove 5 is inclined, so the part of the protective cover 3 that is attached to it is also inclined. The inclined protective cover 3 part is more convenient to drive the first locking block 7 to press the inclined part of the protective cover 3 that is attached to the side wall of the outer shell 1 by sliding the locking plate 6.
[0068] The inserted cable is positioned using the downward limiting groove 4 and the upward limiting groove 5. Then, the cable is clamped and fixed by the second locking block 8 of the locking plate 6, which simultaneously seals the downward limiting groove 4 and the upward limiting groove 5, creating a relatively enclosed space between the interior of the outer casing 1 and the outside. This shielding method, which reduces the number and area of openings, minimizes the impact of electromagnetic pulses on the protected component 11. In this design, the locking of the protective cover 3, the clamping and fixing of the cable, and the downward limiting groove 4 and the upward limiting groove 5 are integrated into a single design and can all be accomplished through the cooperation of the locking plate 6 and the locking assembly. The overall structure is compact and flexible in use.
[0069] The protective assembly includes several filters 12 and a grounding block 13. The filters 12 are installed within the cavity, preferably corresponding one-to-one with the lower limiting groove 4 or the upper supporting limiting groove 5, i.e., each is applied to the cable that passes through. The input end of the filter 12 is used to connect the cable extending into the housing 1, its first output end is used to connect the component 11 to be protected, and its second output end is connected to the grounding block 13 via a conductive member 14. By installing the filter 12 between the cable and the component 11 to be protected, the filter 12 can only allow signals in a preset operating frequency band to pass through, suppressing electromagnetic pulse interference of other frequencies. Connected to the grounding block 13 via a conductive member, the filter 12 effectively grounds the induced current generated by the electromagnetic pulse to the ground without generating interference signals.
[0070] The detection components include an electromagnetic pulse detector, a controller 18, and a display module; the electromagnetic pulse detector is electrically connected to the conductive element 14; the controller 18 is electrically connected to the electromagnetic pulse detector and the display module. By coordinating the electromagnetic pulse detector 15 with the controller 18 to control the display module, the protective device can detect electromagnetic pulse interference and simultaneously display the number of electromagnetic pulse interference occurrences.
[0071] The above is Embodiment 1 of a comprehensive protection device for strong electromagnetic pulses with detection and display functions provided in this application. The following is Embodiment 2 of a comprehensive protection device for strong electromagnetic pulses with detection and display functions provided in this application. Please refer to the following for details. Figures 1 to 6 .
[0072] Based on the solution of Embodiment 1 above:
[0073] Furthermore, the locking component design includes support block 9 and limit member 10.
[0074] The support block 9 is rotatably mounted on the outer casing 1 and located below the locking plate 6 to support the locking plate 6. The support block 9 can rotate itself to support the locking plate 6 when the locking plate 6 is in the locked position, so as to restrict the locking plate 6 to the locked position.
[0075] The limiting member 10 is used to fasten the support block 9 and the outer shell 1 together when the support block 9 supports the locking plate 6 in the locked position, so as to fix the support block 9 and thus complete the locking of the locking plate 6.
[0076] Furthermore, the limiting member 10 is elastically slidably connected to the outer shell 1 along the rotation center line of the support block 9 via an elastic member, and the support block 9 is provided with a slot for the limiting member 10 to be inserted.
[0077] The elastic element provides elastic force to the limiting element 10 in the direction of engaging the slot. When the support block 9 supports the locking plate 6 in the locked position, the limiting element 10 can be moved into the slot under the action of the elastic element to fasten the support block 9 to the outer shell 1. During the unlocking operation, the limiting element 10 can be pressed until it exits the slot without affecting the rotation of the support block 9. Then the support block 9 rotates to release the support of the locking plate 6, and the locking plate 6 slides or slides under its own weight to release the pressure and fastening of the protective cover 3.
[0078] Furthermore, the elastic element is preferably designed as a spring. For ease of installation, a sliding groove can be provided inside the outer casing 1 for the limiting element 10 to slide. A portion of the limiting element 10 extends out of the outer casing 1 through one side of the sliding groove. The elastic element is installed in the sliding groove, with one end contacting and abutting against the limiting element 10, and the other end contacting and abutting against one side of the sliding groove. A slot is provided for the portion of the limiting element 10 extending out of the outer casing 1 to engage. The limiting element 10 can be designed as a sliding block portion that slides in the sliding groove, and an insert portion that connects to the sliding block plate and can be movably engaged in the slot. There can be two insert portions arranged symmetrically in a V-shape, and two corresponding slots are provided, one for each insert portion to engage.
[0079] Furthermore, in order to better support the locking plate 6, an arc-shaped groove is provided on the lower surface of the locking plate 6, and one end of the support block 9 can extend into the arc-shaped groove and fit into the arc-shaped groove.
[0080] Furthermore, while the protective cover 3 is attached to one side wall of the outer shell 1, it also contacts and abuts against one side end face of the cover 2. The contact area is increased, and the stability of the fit is also better.
[0081] The part where the protective cover 3 and the shell cover 2 are hinged is an arc-shaped structure, which can better achieve the hinged fit.
[0082] Furthermore, both the downward limiting groove 4 and the upward limiting groove 5 are U-shaped groove structures, with their openings facing opposite directions for better cable positioning. When the protective cover 3 is attached to one side wall of the outer shell 1, the center of the arc-shaped inner wall of the downward limiting groove 4 coincides with the center of the arc-shaped inner wall of the upward limiting groove 5. One end of the second locking block 8 has a U-shaped groove design, and the outer surface of the second locking block 8 is attached to the inner surface of the downward limiting groove 4, with the center of the arc-shaped inner wall of the second locking block 8 after attachment coinciding with the center of the arc-shaped inner wall of the downward limiting groove 4.
[0083] During installation, such as Figure 6 As shown, the cable is inserted into the housing 1 through the upper limiting groove 5 and connected to the filter 12. Then, the housing cover 2 is flipped down so that the lower surface of the housing cover 2 fits against the upper surface of the housing 1.
[0084] Then, the protective cover 3 is flipped downwards, so that the protective cover 3 engages with the cable through the downward limiting groove 4. At the same time, the protective cover 3 achieves relative sealing between the outer shell 1 and the outside world through the outer surfaces of the outer shell 1 and the outer cover 2.
[0085] Rotating the support block 9 changes it from a horizontal to a vertical state. During this process, the support block 9 presses against the arc-shaped groove in the center of the lower surface of the locking plate 6, causing the locking plate 6 to gradually rise until the support block 9 is completely vertical. At this point, the limiting member 10 partially slides out of the outer shell 1 under the elastic action of the spring and engages with the slot on the side surface of the support block 9, so that the support block 9 maintains stable support for the locking plate 6. Meanwhile, the locking plate 6 is attached to the outer surface of the protective cover 3 through the first locking block 7, preventing the protective cover 3 from rotating. Simultaneously, the cable is further limited by the engagement of the second locking block 8 with the downward limiting groove 4, thus completing the installation of the cable.
[0086] Furthermore, the grounding block 13 is installed on the outer wall of the housing 1, and one end of the conductive element 14 passes through the housing 1 and is connected to the grounding block 13. Adjacent conductive elements 14 are connected to each other.
[0087] The conductive element 14 is a conductive rod. The conductive elements 14 are connected in series to avoid poor grounding caused by the breakage of a single conductive element 14, and to ensure that the filter 12 can always maintain good grounding.
[0088] Furthermore, the detection components are mounted on the grounding block 13, resulting in a more compact structure.
[0089] Furthermore, the display module includes a first counting indicator light 16 and a second counting indicator light 17.
[0090] The electromagnetic pulse detector 15 is connected to one end of the conductive element 14 via a wire, and the electromagnetic pulse detector 15 is electrically connected to the controller 18 via a wire. The controller 18 is electrically connected to the first counting indicator 16 and the second counting indicator 17 via wires respectively.
[0091] When a lightning strike generates an electromagnetic pulse, the abnormal electromagnetic pulse is conducted through the cable to the filter 12. The filter 12 transmits the filtered line signal to the component to be protected 11, while the abnormal electromagnetic pulse signal is transmitted through the conductor 14 to the grounding block 13 for grounding. During this process, the electromagnetic pulse detector 15 monitors the electromagnetic pulse signal on the conductor 14.
[0092] When the electromagnetic pulse detector 15 detects a magnetic pulse signal, it sends an electrical signal to the controller 18. The controller 18 controls the first counting indicator 16 on one side to light up sequentially. When all the first counting indicator 16 are lit, all the first counting indicator 16 are turned off at the same time, and the second counting indicator 17, which is closest to the electromagnetic pulse detector 15 and is not lit, lights up. The staff can read the actual number of electromagnetic pulse interferences by observing the number of first counting indicator 16 and second counting indicator 17 that are lit.
[0093] The above provides a detailed description of a comprehensive protection device for strong electromagnetic pulses with detection and display functions provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
