Description

Technical Field

[0001] This utility model relates to the field of electrical fire protection technology, specifically to an electrical fire protection leakage detection device. Background Technology

[0002] Electrical fire protection refers to a fire protection method that uses electrical equipment and technical means to take measures such as prevention, monitoring, alarm, control and fire fighting to protect the safety of people's lives and property inside buildings or facilities. During the fire protection process, leakage current detectors are used to detect leakage current.

[0003] A search revealed a Chinese patent (CN219799717U) disclosing a fire-fighting electrical leakage detection device. When the battery needs replacing, the device first unscrews the screw, then pulls the horn, causing a limiting block to press against the positioning post and the telescopic spring, allowing the positioning post to enter the positioning groove. The pressing block can then be pulled out, at which point the telescopic spring returns to its original position, pushing the positioning post back to its original position. After the battery replacement is complete, the limiting block is slid into the limiting groove. When the limiting block slides to a certain position, it presses against the positioning post and the telescopic spring, causing the positioning post to enter the positioning groove. When the device slides to the bottom of the limiting groove, the telescopic spring returns to its original position, pushing the positioning pin into the positioning hole. At this time, the positioning pin positions the limiting block, preventing the spring on the pressure block from pushing it up again. The user does not need to press down on the pressure block. After that, tightening the screw will fix the pressure block, thus achieving the effect of easy battery replacement. However, the screw fixing method requires the bolt to be placed separately, which can easily lead to the loss of the screw, affecting the assembly of the fire protection electrical leakage detection device. In addition, the handle on the outside of the leakage detector is easy to slip and rotate, affecting the user's use. Therefore, we propose an electrical fire protection leakage detection device. Utility Model Content

[0004] The technical problem to be solved by this application is that the use of screw fixing requires the bolt to be placed separately, which can easily lead to the loss of the screw, affecting the assembly of the fire electrical leakage detection device, and the handle on the outside of the leakage detector is easy to slip and rotate, affecting the user's use.

[0005] To address the aforementioned technical problems, this application provides an electrical fire protection leakage detection device, comprising a leakage detector and a battery base with a battery placed on top. The lower end of the leakage detector is fitted with an anti-slip sleeve, and grooves are symmetrically formed on the surface of the lower end of the leakage detector. A fixing mechanism is provided inside the grooves to fix the battery base and the anti-slip sleeve.

[0006] In some embodiments, the fixing mechanism includes a side plate and a sliding plate. The side plate is installed at both ends of the top of the battery base and is slidably connected to the lower end of the groove. The sliding plate is slidably installed inside the groove. The sliding plate and the groove are connected by a limiting spring. A pressing block is installed at the middle of the surface of the sliding plate. A first locking block is installed at the upper end of the surface of the sliding plate. A second locking block is installed at the lower end of the surface of the sliding plate. A first locking groove adapted to the size of the second locking block is opened on the inner side of the side plate. A second locking groove adapted to the size of the first locking block is opened at the lower end of the inner side of the anti-slip sleeve.

[0007] In some embodiments, limit blocks are installed at the top and bottom of the groove, and limit grooves adapted to the size of the limit blocks are provided at the top and bottom of the slide plate.

[0008] In some embodiments, the bottom of the pressing block has a slope, and the top of the pressing block has an arc-shaped surface.

[0009] In some embodiments, a retaining ring is also installed at the upper end of the leakage current detector, and the bottom end of the retaining ring is in contact with the top end of the anti-slip sleeve.

[0010] In some embodiments, the outer side of the anti-slip sleeve is provided with a plurality of arc-shaped protrusions arranged in a circular array at equal intervals.

[0011] In some embodiments, two protruding strips are installed on the inner side of the anti-slip sleeve, and a groove adapted to the size of the protruding strips is provided at the lower end of the leakage current detector.

[0012] This utility model has at least the following beneficial effects:

[0013] When the battery or anti-slip cover needs to be replaced, push the pressing block inside the leakage current detector. The pressing block causes the sliding plate, the first locking block, and the second locking block to slide. The sliding plate compresses the limiting spring, and the first locking block disengages from the second locking groove inside the anti-slip cover, releasing the limiting position of the anti-slip cover. The second locking block disengages from the first locking groove on the upper side plate of the battery base, releasing the limiting position of the battery base. The anti-slip cover and battery can then be replaced. During installation, simply slip the anti-slip cover onto the lower end of the leakage current detector, press the pressing block, install the battery base with the battery on the bottom of the leakage current detector, and release the pressing block. The first locking block will lock into the second locking groove inside the anti-slip cover, and the second locking block will lock into the first locking groove on the upper side plate of the battery base, thus fixing the anti-slip cover and battery. The whole system is easy to assemble and less likely to lose parts. The addition of a fixing ring, a protrusion, and a groove further limits the anti-slip cover, preventing it from sliding up and down or rotating, increasing its stability, and making it convenient for users.

[0025] 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.

[0026] Example 1

[0027] Please see Figure 1-5This utility model provides a technical solution: an electrical fire protection leakage detection device, including a leakage detector 1 and a battery base 2 with a battery placed on top. The lower end of the leakage detector 1 is fitted with an anti-slip sleeve 4. Grooves 101 are symmetrically opened on the surface of the lower end of the leakage detector 1. A fixing mechanism 3 is provided inside the groove 101. The fixing mechanism 3 is used to fix the battery base 2 and the anti-slip sleeve 4.

[0028] Furthermore, the fixing mechanism 3 includes a side plate 201 and a sliding plate 7. The side plate 201 is installed at both ends of the top of the battery base 2 and is slidably connected to the lower end of the groove 101. The sliding plate 7 is slidably installed inside the groove 101. The sliding plate 7 and the groove 101 are connected by a limiting spring 6. A pressing block 8 is installed at the middle of the surface of the sliding plate 7. A first locking block 9 is installed at the upper end of the surface of the sliding plate 7. A second locking block 11 is installed at the lower end of the surface of the sliding plate 7. A first slot 2011 adapted to the size of the second locking block 11 is opened on the inner side of the side plate 201. A second slot 403 adapted to the size of the first locking block 9 is opened at the lower end of the inner side of the anti-slip sleeve 4.

[0029] Limiting blocks 10 are installed at the top and bottom of the groove 101, and limiting grooves 701 that are adapted to the size of the limiting blocks 10 are provided at the top and bottom of the slide plate 7. The slide plate 7 is limited by the limiting blocks 10 and the limiting grooves 701, thereby increasing the stability of the slide plate 7.

[0030] The bottom of the pressing block 8 is provided with a slope, and the top of the pressing block 8 is provided with an arc surface. The slope and arc surface reduce the frictional resistance between the anti-slip sleeve 4 and the pressing block 8 when disassembling the anti-slip sleeve 4.

[0031] Furthermore, a fixing ring 5 is installed at the upper end of the leakage current detector 1. The bottom end of the fixing ring 5 is in close contact with the top end of the anti-slip sleeve 4. Multiple arc-shaped protrusions 401 are installed equidistantly and in a circular array on the outer side of the anti-slip sleeve 4. The anti-slip sleeve 4 is made of sponge material, and the arc-shaped protrusions 401 are made of rubber material. The arc-shaped protrusions 401 increase the friction with the user's palm and achieve an anti-slip effect. Two protrusions 402 are installed on the inner side of the anti-slip sleeve 4. A groove 102 that matches the size of the protrusions 402 is opened at the lower end of the leakage current detector 1. The protrusions 402 and the groove 102 limit the anti-slip sleeve 4 and prevent the anti-slip sleeve 4 from rotating on the surface of the leakage current detector 1.

[0032] When the battery or anti-slip sleeve 4 needs to be replaced, push the pressing block 8 into the leakage current detector 1. The pressing block 8 causes the sliding plate 7, the first locking block 9, and the second locking block 11 to slide. The sliding plate 7 compresses the limiting spring 6, and the first locking block 9 disengages from the second locking groove 403 inside the anti-slip sleeve 4, releasing the limiting of the anti-slip sleeve 4. The second locking block 11 disengages from the first locking groove 2011 on the upper side plate 201 of the battery base 2, allowing the anti-slip sleeve 4 and battery to be replaced. During installation, simply slip the anti-slip sleeve 4 onto the lower end of the leakage current detector 1, so that the protrusion 402 is located in the sliding groove 102 of the leakage current detector 1, and the inclined surface of the pressing block 8 is flush with the anti-slip sleeve 4. The top contact causes the pressing block 8 to slide into the leakage detector 1. The anti-slip sleeve 4 continues to slide, and the battery base 2 with the battery is installed at the bottom of the leakage detector 1. Then, the anti-slip sleeve 4 is slid upward so that the top of the anti-slip sleeve 4 fits against the bottom of the fixing ring 5. At this time, the pressing block 8 is not squeezed by the anti-slip sleeve 4. The rebound force of the limiting spring 6 causes the sliding plate 7, the first locking block 9 and the second locking block 11 to slide in opposite directions, so that the first locking block 9 is locked in the second locking groove 403 on the inner side of the anti-slip sleeve 4, and the second locking block 11 is locked in the first locking groove 2011 on the upper side plate 201 of the battery base 2, thereby fixing the anti-slip sleeve 4 and the battery.

[0033] Example 2

[0034] Please see Figure 6-8 This utility model provides a technical solution: Based on embodiment 1, this utility model provides another technical solution: The upper end of the leakage current detector 1 is fitted with a protective sleeve 12, and the lower end of the protective sleeve 12 is connected to the middle end of the leakage current detector 1 by an elastic rope 13. A bottom ring 14 is installed at the middle end of the leakage current detector 1 and above the elastic rope 13. The lower end of the inner side of the protective sleeve 12 is provided with a triangular ring protrusion 1201. The surface of the bottom ring 14 is provided with a positioning groove 1401 that matches the size of the protective sleeve 12 and the protrusion 1201. The protrusion 1201 is deformable and plays the role of fixing the protective sleeve 12. When the protective sleeve 12 is pulled upward, the protrusion 1201 deforms and disengages from the positioning groove 1401, thereby releasing the limitation of the protective sleeve 12. The protective sleeve 12 shields and protects the components at the upper end of the leakage current detector 1.

[0036] Please see Figure 9 and Figure 10 This utility model provides a technical solution: Based on the above embodiments, this utility model provides another technical solution: A collar 15 is installed in the middle of the leakage current detector 1. The collar 15 is located between the bottom ring 14 and the fixing ring 5. A hanging strap 16 is installed at one end of the collar 15. The hanging strap 16 is used to be put on the outside of the belt. The two ends of the hanging strap 16 are provided with Velcro that fits together. When not in use, the hanging strap 16 can be easily fixed to the outside of the belt by the Velcro, freeing the user's hands.
