Technical Field

[0001] This utility model relates to the field of electrical protection technology for ancient buildings, specifically a circuit breaker for detecting electric arc in electrical fires in ancient buildings. Background Technology

[0002] Ancient buildings typically possess significant historical and cultural value, making the safety of their electrical systems paramount. Therefore, when providing electrical protection for the electrical equipment used in ancient buildings, fault arc detectors can promptly detect and warn of fault arcs in the electrical system, preventing fires caused by high-temperature burning, prolonged heat accumulation, and electrical sparks. During operation, they can monitor and manage parameters such as residual current and conductor temperature in the power distribution circuit in real time, ensuring the safe operation of the electrical system of ancient buildings and protecting cultural relics from damage.

[0003] Currently, existing arc detection circuit breakers for electrical fires in ancient buildings are mostly fixed to the electrical control cabinet using DIN rail mounting. However, considering that multiple arc detection circuit breakers are usually installed on the DIN rail simultaneously, during dense installation, adjacent arc detection circuit breakers may generate mutual electromagnetic interference due to being too close together. This affects the normal detection of electrical circuits in ancient buildings by the arc detection circuit breakers and increases the probability of detection errors. Therefore, to address the above problems, an arc detection circuit breaker for electrical fires in ancient buildings is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a circuit breaker for detecting electric arc in electrical fires in ancient buildings, in order to solve the problem mentioned in the background art that when two adjacent devices are used, they are prone to mutual electromagnetic interference.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An arc detection circuit breaker for electrical fires in ancient buildings includes a detection housing. A side groove is formed in the middle of the side of the detection housing. A slide bar is slidably connected to the rear side of the detection housing. A scale plate is fixedly connected to the upper front end of the slide bar. A side retaining frame is fixedly connected to the side of the slide bar away from the detection housing. A limiting slot is formed in the middle of the inner side of the side retaining frame. A carbon fiber modified partition is fitted inside the side retaining frame. A limiting guide rail is fitted inside the rear guide groove of the detection housing. An adjustment slot is formed below the front end of the slide bar. A pin is engaged inside the adjustment slot. An inner buckle plate is fixedly connected to the rear inner side of the side groove. A movable slide rod passes through the middle of the inner buckle plate. A chuck is fixedly connected to the front end of the movable slide rod. A spring is sleeved on the outside of the movable slide rod.

[0007] Preferably, an outward protrusion is fixedly installed at the middle position of the front end of the detection housing, and a digital display screen is provided at the left side of the front end of the outward protrusion.

[0008] Preferably, the top of the detection housing is provided with a wiring terminal, and the lower right corner of the detection housing is provided with an alarm. There are a total of 2 wiring terminals.

[0009] Preferably, the protruding plate at the rear end of the carbon fiber modified partition extends rearward through the interior of the limiting slot, and the protruding plate at the rear end of the carbon fiber modified partition is engaged with the inner side of the limiting guide rail.

[0010] Preferably, a plurality of the defined guide rails are arranged in an equidistant structure along the horizontal direction, the rear end of the movable slide rod extends into the reserved slide groove between the detection housing and the slide bar, and the rear end of the movable slide rod is fixedly connected to the pin, the front and rear ends of the spring are fixedly connected to the chuck and the inner buckle plate respectively, and two sets of slide bars are provided in each group of two, and the inner space of the side frame is equal in size to the thickness of the carbon fiber modified partition.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the carbon fiber modified partition, pin, slide bar, adjusting slot, side slot, and scale plate facilitate the assembly of multiple testing devices before the use of the arc detection circuit breaker for electrical fires in ancient buildings.

[0019] 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.

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] An arc detection circuit breaker for electrical fires in ancient buildings includes a detection housing 1. A side groove 3 is provided in the middle of the side of the detection housing 1. A slide bar 4 is slidably connected to the rear side of the detection housing 1. A scale plate 5 is fixedly connected to the upper front end of the slide bar 4. A side retaining frame 7 is fixedly connected to the side of the slide bar 4 away from the detection housing 1. A limiting slot 18 is provided in the middle of the inner side of the side retaining frame 7. A carbon fiber modified partition 13 is fitted inside the side retaining frame 7. A limiting guide rail 8 is fitted inside the guide groove at the rear end of the detection housing 1. An adjustment slot 6 is provided below the front end of the slide bar 4. A pin 14 is engaged inside the adjustment slot 6. An inner buckle plate 9 is fixedly connected to the rear inner side of the side groove 3. A movable slide rod 10 passes through the middle of the inner buckle plate 9. A chuck 11 is fixedly connected to the front end of the movable slide rod 10. A spring 12 is sleeved on the outside of the movable slide rod 10.

[0022] like Figure 1 As shown, an outward protrusion 2 is fixedly installed at the middle of the front end of the detection housing 1. A digital display screen 16 is provided at the left side of the front end of the outward protrusion 2. The digital display screen 16 is mainly used to monitor the data in real time during the detection process. A wiring terminal 15 is provided on the top of the detection housing 1. An alarm 17 is provided at the lower right corner of the detection housing 1. There are two wiring terminals 15. When the device detects an abnormal power consumption problem, the alarm 17 will sound an alarm to remind the user.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the protruding plate at the rear end of the carbon fiber modified partition 13 extends backward through the interior of the limiting slot 18. The protruding plate at the rear end of the carbon fiber modified partition 13 is engaged with the inner side of the limiting guide rail 8. The backward extension of the protruding plate allows the carbon fiber modified partition 13 to be auxiliaryly limited when inserted into the slot. Several limiting guide rails 8 are arranged equidistantly along the horizontal direction. The rear end of the movable slide rod 10 extends into the reserved groove between the detection housing 1 and the slide bar 4. The rear end of the movable slide rod 10 is fixedly connected to the pin 14. The front and rear ends of the spring 12 are fixedly connected to the chuck 11 and the inner buckle plate 9, respectively. There are two sets of slide bars 4, with two bars in each set. The inner space of the side frame 7 is equal to the thickness of the carbon fiber modified partition 13. The matching of inner and outer dimensions facilitates the precise mounting of the carbon fiber modified partition 13.

[0024] Workflow: The electrical power required for the start-up and operation of the detection equipment in this utility model comes from the main electrical control power system of the ancient building. Before installing the detection equipment into the corresponding electrical cabinet, it is necessary to ensure that the limiting guide rail 8 is pre-fixed therein. Before using the arc detection circuit breaker to perform fire detection on the electrical system inside the ancient building, multiple detection devices need to be fixed into the electrical cabinet. As each detection housing 1 is connected to the limiting guide rail 8 through the guide groove reserved on the back and fixed by the rebound buckle on the back, you can insert your hand into the inside of the side groove 3 and move the movable slide rod 10 forward through the chuck 11. It will move forward synchronously with the pin 14, separating from the single adjustment slot 6. Then, use the scale on the scale plate 5 for precise indication, firmly grasp the side frame 7 and pull the slide bar 4 outward. When it is pulled out to a suitable length range (such as 5-7cm), stop pulling the slide bar 4. At this time, the spring 12 begins to release and rebound, and the movable slide rod 10 moves backward with the pin 14. The pin 14 will re-engage with another adjustment slot 6. Connected together, the sliding bar 4 is limited. Then, aligned with the inside of the side frame 7 and the limiting slot 18, the carbon fiber modified partition 13 is inserted from front to back. After the outer protrusion of the rear end of the carbon fiber modified partition 13 penetrates the inside of the limiting slot 18 and is engaged in the limiting guide rail 8, the carbon fiber modified partition 13, as an electromagnetic shielding protection component, can be installed in place. This allows two adjacent arc detection circuit breakers to be installed relative to each other with a precise and appropriate installation spacing through the graduated separation assembly composed of the sliding bar 4, adjusting slot 6, side slot, and scale plate 5. At the same time, the two can also isolate the electromagnetic interference generated by each other during operation through the carbon fiber modified partition 13 installed on the side frame 7. Then, when the arc detection circuit breaker is connected to the electrical circuit of the ancient building through the terminal 15 and detects a problem with the operation of the electrical circuit of the ancient building, the arc detection circuit breaker will sound an alarm through the alarm 17 to monitor the management personnel of the ancient building, thereby achieving the purpose of fire prevention and electrical protection.

[0025] 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.
