Description

Technical Field

[0001] This utility model relates to the field of fault arc detection technology, specifically to a fault arc detection device that can be used with both AC and DC. Background Technology

[0002] Arc faults are a common but difficult-to-detect phenomenon in low-voltage power distribution networks and building circuits. Prolonged high-load operation of low-voltage power distribution lines, aging of lines, and damage to insulation layers can all easily lead to arc faults. Arc faults have become one of the main causes of electrical fires. To prevent such fires, the installation of appropriate protective products is commonly used.

[0003] In the prior art, Chinese utility model application number CN202122840275.4 discloses a fault arc detection device that can be used with both AC and DC, including a fault arc detection device body, an anti-interference device, and a positioning groove. The positioning groove is located on the right side of the front side of the fault arc detection device body. Arc-shaped grooves are formed at the bottom of both sides of the inner wall of the positioning groove. A plug-in block is inserted into the positioning groove. A through hole is formed inside the plug-in block. A positioning mechanism is set inside the through hole. This utility model can achieve good anti-interference by setting an anti-interference device on the front side of the fault arc detection device body.

[0004] However, the anti-interference device in this technical solution does not have an installation status display structure during installation. As a result, although the plug-in block is inserted into the positioning slot, the arc-shaped block of the positioning mechanism does not pop out and engage with the arc-shaped slot, which leads to unstable installation of the anti-interference device, increases the risk of misinstallation, and the plug-in block is inconvenient to disassemble, making it inconvenient to disassemble and maintain the anti-interference device. Therefore, we need to propose a fault arc detection device that can be used for both AC and DC. Utility Model Content

[0005] The purpose of this utility model is to provide a fault arc detection device that can be used with both AC and DC. By setting up a positioning structure to display the installation status, it is convenient to understand the installation status of the positioning structure and avoid the occurrence of misinstallation or loose installation. At the same time, the positioning mechanism facilitates the quick disassembly of the anti-interference device, thereby improving the convenience of maintenance of the anti-interference device and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fault arc detection device applicable to both AC and DC, comprising:

[0007] The main body of the fault arc detection device, and the anti-interference device installed on the main body of the fault arc detection device;

[0008] The mounting base for installing the anti-interference device has a mounting hole on the upper surface of the fault arc detection device body for inserting the mounting base. The mounting base is provided with a positioning mechanism to fix the mounting base in the mounting hole, so as to facilitate the quick installation and removal of the anti-interference device.

[0009] The fault arc detection device body is equipped with two sets of quick-locking mechanisms and mounting components for positioning the fault arc detection device body through the two sets of quick-locking mechanisms.

[0010] Preferably, the positioning mechanism includes a partition and two sets of connecting plates. Two sets of springs are provided on opposite sides of the two sets of connecting plates, and the ends of the two sets of springs away from the connecting plates are fixedly connected to the partition. A lever is fixedly connected to the upper end of one side of the two sets of connecting plates, and a positioning block penetrating the mounting base is fixedly connected to the lower end of one side of the two sets of connecting plates.

[0011] Preferably, the mounting base includes two sets of symmetrically arranged inserts. One side of each insert has a third through groove for mounting the partition. Both ends of the partition and the spring member are provided with locking blocks. One side of the third through groove has a locking slot for inserting the locking blocks.

[0012] Preferably, a first through groove is provided on the upper end of one side of the insert block for the sliding of the lever, and a second through groove is provided on the lower end of one side of the insert block for the sliding of the positioning block. The first through groove and the second through groove are connected by a third through groove. One set of insert blocks has multiple sets of protrusions on one side, and another set of insert blocks has a groove on one side for multiple sets of protrusions to be inserted.

[0013] Preferably, the inner wall of the mounting hole is symmetrically provided with two sets of guide grooves for the positioning block to slide, and the bottom of the guide groove is provided with a positioning hole for the positioning block to be inserted.

[0015] Preferably, the mounting component includes a base plate, both sides of which are provided with side grooves for inserting two sets of locking blocks, and the upper surface of the base plate is fitted with multiple sets of fixing bolts for fastening the base plate, and the lower surface of the fault arc detection device body is provided with a storage groove for embedding the base plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model mainly utilizes the cooperation between the mounting base, positioning mechanism, mounting hole, and the main body of the fault arc detection device. The positioning mechanism can be easily and quickly installed in the mounting hole, thereby allowing the mounting base to be installed in the mounting hole for rapid installation of the anti-interference device. Furthermore, by observing the opening and closing of the positioning mechanism, it is possible to determine whether the positioning mechanism has been installed, thus facilitating the assessment of installation stability. Simultaneously, pressing the positioning mechanism can easily release the locking of the mounting base, making it convenient to remove and maintain the anti-interference device, thus improving the ease of disassembly and assembly.

[0018] 2. This utility model utilizes the cooperation between the quick-locking mechanism and the mounting component. The mounting component is installed inside the cabinet by fixing bolts, thereby fitting the storage slot of the fault arc detection device body with the base plate.

[0023] 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.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a fault arc detection device applicable to both AC and DC, comprising:

[0025] The main body 1 of the fault arc detection device, and the anti-interference device 4 installed on the main body 1 of the fault arc detection device;

[0026] The mounting base 2 is used for installing the anti-interference device 4. The upper surface of the fault arc detection device body 1 is provided with a mounting hole 6 for the mounting base 2 to be inserted. The mounting base 2 is provided with a positioning mechanism 3 to fix the mounting base 2 in the mounting hole 6, so as to facilitate the quick installation and removal of the anti-interference device 4.

[0027] The main body 1 of the fault arc detection device is equipped with two sets of quick-locking mechanisms 5 and mounting parts 9 for positioning the main body 1 of the fault arc detection device through the two sets of quick-locking mechanisms 5.

[0028] The positioning mechanism 3 includes a partition 31 and two sets of connecting plates 34. Two sets of springs 33 are provided on opposite sides of the two sets of connecting plates 34, and the ends of the two sets of springs 33 away from the connecting plates 34 are fixedly connected to the partition 31. A lever 35 is fixedly connected to the upper end of one side of the two sets of connecting plates 34, and a positioning block 36 penetrating the mounting base 2 is fixedly connected to the lower end of one side of the two sets of connecting plates 34. The spring 33 consists of a telescopic sleeve and a spring. The spring is sleeved on the outside of the telescopic sleeve, and the two ends of the telescopic sleeve are fixedly connected to opposite sides of the partition 31 and the connecting plate 34, respectively. At the same time, by pressing the lever 35, the two sets of connecting plates 34 are brought closer together, which facilitates the relative adjustment of the distance between the two sets of positioning blocks 36, so that the positioning blocks 36 can be stored in the second through groove 23, and the mounting base 2 can be pulled out of the mounting hole 6.

[0029] Mounting base 2 includes two sets of symmetrically arranged inserts 21. One side of the insert 21 is provided with a third through groove 24 for mounting the partition 31. Both ends of the partition 31 and the spring member 33 are provided with locking blocks 32. One side of the third through groove 24 is provided with a slot 25 for the locking blocks 32 to be inserted. By the locking blocks 32 on the partition 31 engaging with the slots 25 in the third through groove 24, the overall installation of the positioning mechanism 3 is convenient, thus facilitating the disassembly and assembly of the positioning mechanism 3. The overall structure is simple.

[0030] The upper end of one side of the insert block 21 is provided with a first through groove 22 for the lever 35 to slide, and the lower end of one side of the insert block 21 is provided with a second through groove 23 for the positioning block 36 to slide. The first through groove 22 and the second through groove 23 are connected by a third through groove 24. One set of insert blocks 21 is provided with multiple sets of protrusions 26 on one side, and another set of insert blocks 21 is provided with a groove 27 for multiple sets of protrusions 26 to be inserted into one side. The first through groove 22 facilitates the movement of the lever 35, the second through groove 23 facilitates the storage of the positioning block 36, and the third through groove 24 facilitates the installation of the connecting plate 34 and the partition plate 31. The overall structure is simple and reduces production costs.

[0031] Two sets of guide grooves 7 are symmetrically provided on the inner wall of the mounting hole 6 for the positioning block 36 to slide. The bottom of the guide groove 7 is provided with a positioning hole 8 for the positioning block 36 to be inserted. The guide groove 7 facilitates the guidance of the positioning block 36 of the positioning mechanism 3 before it is inserted into the positioning hole 8. The guide groove 7 is curved so that the mounting base 2 can be rotated 180 degrees and installed in the mounting hole 6. At the same time, the positioning block 36 needs to slide along the guide groove 7 into the positioning hole 8, which improves the stability of the mounting base 2 installed in the mounting hole 6.

[0032] Both sets of quick-locking mechanisms 5 include a bidirectional screw 51 and two sets of locking blocks 52. The two sets of locking blocks 52 are threaded to both ends of the bidirectional screw 51. The upper surface of the fault arc detection device body 1 is provided with a connecting groove 11 for the two sets of locking blocks 52 to slide. One end of the bidirectional screw 51 passes through the fault arc detection device body 1 and is fixed with a butterfly knob 53. Each connecting groove 11 is provided with a cover plate 12. By rotating the knob, the bidirectional screw 51 can be easily driven to rotate, thereby facilitating the relative movement of the two sets of locking blocks 52 so that the fault arc detection device body 1 can be installed on the mounting part 9. This improves the ease of disassembly and assembly of the fault arc detection device body 1. In addition, the cover plate 12 can prevent dust from falling on the bidirectional screw 51, thereby improving the service life of the bidirectional screw 51.

[0033] Mounting component 9 includes a base plate 91. Both sides of the base plate 91 have side grooves 93 for inserting two sets of locking blocks 52. Multiple sets of fixing bolts 92 for fastening the base plate 91 are inserted into the upper surface of the base plate 91. The lower surface of the fault arc detection device body 1 has a storage groove 10 for embedding the base plate 91. The base plate 91 can be easily installed in any position inside the cabinet by multiple sets of fixing bolts 92, thereby improving the flexibility of the installation position of the fault arc detection device body 1. At the same time, the cross-section of the side grooves 93 is trapezoidal, which facilitates the insertion of the locking blocks 52 to lock the fault arc detection device body 1.

[0034] In use, align the two sets of positioning blocks 36 with the upper ends of the two sets of guide grooves 7 on the mounting hole 6 and insert them. Press the anti-interference device 4 so that it moves along the guide grooves 7 with the mounting base 2 through the positioning blocks 36 and inserts into the mounting hole 6. After the mounting base 2 rotates 180 degrees, the positioning blocks 36 are inserted into the positioning holes 8 under the action of the spring 33. At the same time, the lever 35 moves away from each other, thus completing the positioning of the mounting base 2. The stability of the mounting base 2 can be judged by the position of the lever in the first through groove 22. When the two sets of levers abut against the side wall of the first through groove 22, it means that the positioning blocks 36 are inserted into the positioning holes 8 and the mounting base 2 is fixed. Otherwise, the positioning blocks 36 are not inserted into the positioning holes 8, so the installation position of the mounting base 2 needs to be readjusted to avoid the anti-interference device 4 falling off due to misinstallation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
